The purpose of positioning is to be able to process it and ensure that it will not move during the machining process, resulting in machining failure. A clamp is needed to fix the raw materials.

[0003] Chinese patent CN220660046U discloses a mechanical processing positioning device. The mechanical processing positioning device uses a lever to exert force on the inner gear ring to make it rotate, and the gear rack mechanism converts the rotation into linear motion, so that the four claws can be gathered at the same time and stroke, and then the rotating handle is rotated to lock the lever, so as to achieve rapid self-centering of relatively regular workpieces.

DETAILED DESCRIPTION

[0044] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0045] See also Figure 1-Figure 10 As shown, a mechanical processing positioning device with an angle adjustment function includes a chassis 100, which is a hollow disc. The chassis 100 is provided with four groups of slide grooves 101 equidistantly distributed along its circumferential direction. A clamping claw 200 is slidably fitted in the slide groove 101. A placement plate 102 is rotatably provided on the chassis 100, and two sliders 107 are symmetrically provided on the side of the placement plate 102. The chassis 100 is provided with an annular slide groove 106 for the slider 107 to slide, and the chassis 100 is provided with an angle adjustment mechanism 300 capable of horizontally rotating the placement plate 102.

[0046] When positioning the parts to be processed, the parts are placed on the placement plate 102, and the four groups of jaws 200 are driven so that the jaws 200 can move radially on the chassis 100, thereby being suitable for clamping workpieces of different sizes. The angle adjustment mechanism 300 can adjust the horizontal rotation angle of the placement plate 102, thereby being able to adjust the angle of the workpiece placed on the placement plate 102, so that the four groups of jaws 200 can fully clamp and position the workpiece, which is convenient for processing the workpiece and solves the problem of unstable clamping caused by the mismatch between the clamping angle of the workpiece and the jaws 200.

[0047] See also Figure 4-Figure 6 As shown, the angle adjustment mechanism 300 includes a fixed block 301, a screw rod 302, a threaded block 303, a limit rod 304 and an adjustment rod 306. Two adjustment rods 306 are provided, one end of each of the two adjustment rods 306 is rotatably connected to the bottom surface of the placement plate 102, and the two adjustment rods 306 are mirror-imaged along the diameter of the placement plate 102. The fixed block 301 is fixed on the chassis 100, one end of the screw rod 302 is rotatably connected to the fixed block 301, and the other end of the screw rod 302 rotates to penetrate the side wall of the chassis 100 and extends outward. The screw rod 302 is provided with two sections of threads with opposite screw directions, and the threaded blocks 303 are provided with two threads and are threadedly sleeved on the screw rod 302. The two threaded blocks 303 are respectively located at two different sections of threads. The other ends of the two adjusting rods 306 are rotatably connected to the two threaded blocks 303. One end of the limit rod 304 is fixedly provided on the side of the fixed block 301, and the other end thereof is fixedly connected to the inner wall of the chassis 100. The limit rod 304 is arranged parallel to the screw rod 302, and the threaded block 303 is provided with a limit through hole for limiting the movement of the limit rod 304.

[0048] When it is necessary to adjust the clamping angle of the workpiece on the placement plate 102, the screw rod 302 is rotated to drive the two threaded blocks 303 to move in opposite directions of the screw rod 302 by the rotation of the screw rod 302. Since the two adjustment rods 306 are rotatably connected to the two threaded blocks 303 respectively, when the threaded blocks 303 move, the adjustment rods 306 will push the placement plate 102 to rotate around its center, thereby changing the angle of the placement plate 102. The limiting rods 304 and the limiting perforations ensure that the threaded blocks 303 move linearly on the screw rod 302 to prevent them from rotating, thereby ensuring the accuracy of the adjustment, so that the workpiece on the placement plate 102 matches the clamping angle of the claws 200.

[0049] See also Figure 8-Figure 10 As shown, the clamping claw 200 includes a clamping plate 201, a vertical plate 202, a sliding plate 203 and a mounting plate 207;

[0051] When positioning the workpiece on the placement plate 102, the clamping plates 201 are moved closer to each other by driving the clamping claws 200 to clamp and position workpieces of different sizes. The buffer member provides a buffer force for clamping, and the height adjustment assembly 400 is used to adjust the height of the clamping plate 201 to meet the clamping requirements of workpieces of different heights.

[0052] See also Figure 8 As shown, the buffer component includes a slide bar 204, a spring 205 and a limit adjustment block 206. One end of the slide bar 204 is fixedly connected to the side of the clamping plate 201, and the other end of the slide bar 204 slides through the mounting plate 207 and extends outward. The spring 205 is sleeved on the slide bar 204, and the two ends of the spring 205 are respectively abutted against the sides of the clamping plate 201 and the mounting plate 207. The limit adjustment block 206 is threadedly arranged at one end of the slide bar 204 that passes through the mounting plate 207 and extends outward.

[0053] When the clamping plate 201 clamps and positions the workpiece, the spring 205 is compressed to provide a buffer force for clamping. The setting of the slide rod 204 enables the spring 205 to move in the horizontal direction without deviation. The limit adjustment block 206 is used to adjust the compression amount of the spring 205, thereby adjusting the size of the clamping force.

[0054] See also Fig. 9 and Fig.10 As shown, the height adjustment component 400 includes a limit slider 403, an adjustment slide rod 404 and a locking nut 405, one end of the adjustment slide rod 404 is fixed on the clamping plate 201 and close to the side of the vertical plate 202, the vertical plate 202 is provided with an adjustment groove 401 for the adjustment slider 404 to slide, the other end of the adjustment slide rod 404 slides through the adjustment groove 401, the locking nut 405 is threadedly sleeved on one end of the adjustment slide rod 404 passing through the adjustment groove 401, the limit slider 403 is symmetrically provided with a pair, and is fixed on the mounting plate 207 and close to the side of the vertical plate 202, the side of the vertical plate 202 is provided with a limit slider 402 for the limit slider 403 to slide, and the number of the limit slider 402 is the same as that of the limit slider 403 and corresponds one to one.

[0055] The adjusting slide bar 404 slides up and down in the adjusting slot 401 . By adjusting the position of the adjusting slide bar 404 in the adjusting slot 401 and fixing the locking nut 405 , the height of the clamping plate 201 can be adjusted to meet the clamping requirements of workpieces of different heights.

[0056] See also Figure 5 and Figure 6 As shown, the screw rod 302 passes through the side wall of the chassis 100 and an operating panel 305 is fixedly provided at one end thereof extending outward.
