A new three-dimensional micrometer probe
To the top of a pair of bellows one of one of the axial force of 12, z direction of the two pairs of bellows subjected to radial force, and the y axis, both of a pair of bellows a certain resistance to rotation around the y-axis features. Measuring the force and moment are all of these make Shu head end contacts with the workpiece, the workpiece when the probe from the right, the various force and torque and to automatically return to zero when the displacement is not large (eg less than 200 ~ Lm),[link widoczny dla zalogowanych], a slight rotation around the y-axis and the displacement of an ideal linear circuit can change the pulse method is ideally equivalent compensation Park, corner of Abbe error caused by the presence of. Meanwhile, the combined effects of six bellows, but also play a role in guiding the direction along the work. Similarly,[link widoczny dla zalogowanych], the direction of the other. 2. Probe zero damping and locking mechanism to ensure the http header has a good dynamic characteristics and promote its ability to quickly return to zero, the damping body rinse the first set, as shown in Figure 1, 8,9. Block damping damping bodies immersed in methyl silicone oil silicone oil box, the other side of the body through the damper rod connected with the core. The shaved a total of two damper lock when you need a certain direction, you can suck through the electromagnetic suction ball-side institutions 1o l1, and the ball end and the lock lever 12, even as one body with the central core 15 connected to implements a direction of the lock,[link widoczny dla zalogowanych], while allowing freedom of movement set the other two directions, y, z directions of each set of three locking mechanism, all through the lock lever and the core bulk connections. Zero solenoid locking mechanism is installed on top of the main shell. 3. Balance of body weight http header in the upper part of the probe device and optical interferometry measuring rod and central core lower body weight added to the bellows, in order to ensure that the central core body is made up of six flexible bellows determined by their own free Ideally, the use of the extension spring probe 5 (total 4) and to link the central core in order to maintain body weight balance. Extension spring and the center of the top shell to link the bottom with the nut 4 is connected to a balance transfer. Cylinder head screw nut 2 and 4 almost matched tone, 2 3 and balance through the block off associated support plate 1, 1 and the bulk connection with the central core. Block off one end and the supporting plate 3 1 phase fixed, the other side of the rectangular slot with the nut 4 match. 2 Turn the cylinder head screws, nuts, does not follow the turning 4, but only with the screw 2 production relative axial movement. Thus, the length of the spring balance can be adjusted, resulting in changes in elastic force, to adjust the balance of the day in the four probe extension spring, located in the central position of the core body of the four vertices, the use of comprehensive adjustment is required. I. Displacement sensor probe body shown in Figure 1 Figure 2 and Figure 3, the head of the Department of measuring body for precision three-dimensional displacement sensing small displacement measuring device, application of the device can simultaneously five. y, z displacement in three directions precision measurement. As long as the touch probe moves, the central core will drive the upper body three-dimensional interferometer while the size of the amount of movement of its mobile, can be ugly. y, z three changes of interference fringes reflected. There are three mirrors, fixed on the shell installed in the probe, and can be adjusted, adjust, y, z three Fangxiang Hu plane mirror,[link widoczny dla zalogowanych], adjust the size of the signal interference fringes. Finally, the photoelectric conversion by the PIN-FET receiver preamplifier components and converted into electrical signals, and then changes the electrical signal for further processing, can achieve displacement sensing probe. Be pointed out that; if the probe direction and the displacement measured Jing, y, z axis at any angle, its displacement by the three directions the last three sets of independent displacement values calculated by a formula that is: aR = '/; + A; + A;. He-Ne single-mode fiber coherent beam 7 through 0.6328pm introduced by the fixed slot, thus reducing the temperature on lap 3 of the probe. Barium agency head also set limit. To achieve anti-collision protection,[link widoczny dla zalogowanych], the upper measuring rod 17 made of spherical, and their insurance with the lower measuring rod 16 made of cylindrical sets, sets of spherical and cylindrical parts connected by screws. When the probe is less than 1N, the above two connections, when the force is greater than lN when relative rotation occurs between the two, thereby protecting the internal probe related to part Buzhi Yu excessive force storm damaged more detailed description of this a new type of three-dimensional micrometer probe. Repeated experiments show that this two-way contact rinse head duplicate measurement accuracy is better than the total pension d = 0.43m. Due to space constraints, this analysis of specific structural principle, computing, and the base surface of the probe accuracy test Dengjun NES introduced.
