DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figures 1-5 The present invention provides a technical solution: a clamping workbench for hardware processing, comprising a workbench 1, a bracket 2 is fixedly connected to the lower surface of the workbench 1, a clamping mechanism 3 is arranged on the upper surface of the workbench 1, a lifting mechanism 4 is arranged on the upper surface of the workbench 1, and a positioning mechanism 5 is arranged on the upper surface of the workbench 1;

[0025] The positioning mechanism 5 includes a positioning block 501, a second bolt 502, a positioning box 503, a limiting plate 504, a limiting hole 505, a spring 506, a clamping block 507 and a positioning pin 508. The upper surface of the workbench 1 is fixedly connected with the positioning block 501, the inner side of the positioning block 501 is penetrated by the second bolt 502, the inner surface of the positioning block 501 is fixedly connected with the positioning box 503, the upper surface of the positioning box 503 is fixedly connected with the limiting plate 504, the surface of the limiting plate 504 is provided with a limiting hole 505, the inner surface of the positioning box 503 is fixedly connected with the spring 506, the other end of the spring 506 is fixedly connected with the clamping block 507, the upper surface of the clamping block 507 is fixedly connected with the positioning pin 508, through the positioning block 501, the second bolt 502, the positioning box 503, the limiting plate 504, the limiting hole 505, the spring 506, the clamping block 507 and the positioning pin 508 The setting is that when in use, the hardware is put in, and the positioned hardware squeezes the positioning pin 508, and the block 507 compresses the spring 506 to move backward, thereby providing a certain buffer and adaptation space for the positioning of the hardware. When the placement is completed, the elastic force of the spring 506 will push the block 507 and the positioning pin 508 to make them tightly against the hardware to achieve stable positioning. The limit plate 504 is fixed to the upper surface of the positioning box 503, and the limit hole 505 opened thereon is used to limit the movement range of the positioning pin 508 to ensure that it moves within the specified range. The block 507 can ensure that the positioning pin 508 does not extend excessively, thereby ensuring the accuracy and stability of positioning. Another set of positioning boxes 503 is fixedly connected to the surface of one side of the connecting block 404, and the two sets of positioning boxes 503 correspond to each other. Through the setting of the two sets of positioning mechanisms 5, the hardware can be accurately, stably and flexibly positioned.

[0026] Furthermore, there are two sets of brackets 2, which are symmetrically arranged with respect to the central axis of the workbench 1. With the arrangement of the brackets 2, more balanced and stable support can be provided during use. The symmetrical structure can ensure that the load borne by the workbench 1 is evenly distributed on the two brackets 2, avoiding the situation where the workbench 1 tilts or becomes unstable due to excessive unilateral force.

[0027] Furthermore, the clamping mechanism 3 includes a support column 301, a first bolt 302, a clamping table 303, a sliding groove 304, a sliding block 305, a clamping block 306, an anti-slip block 307, a threaded rod 308, a grip 309 and a fixed block 310. The upper surface of the workbench 1 is fixedly connected with the support column 301. The first bolt 302 penetrates through the inner side of the support column 301. The upper surface of the support column 301 is fixedly connected with the clamping table 303. A sliding groove 304 is formed on one side surface of the clamping table 303. The inner surface of the sliding groove 304 is slidably connected with the sliding block 305. One side surface of the sliding block 305 is fixedly connected with the clamping block 306. One side surface of the clamping block 306 is fixedly connected with the anti-slip block 307. One side surface of the sliding block 305 is fixedly connected with the threaded rod 308. The other end of the threaded rod 308 is fixedly connected with the grip 309. The surface of the clamping table 303 is fixedly connected with the fixed block 310. With the arrangement of the support column 301, the first bolt 302, the clamping table 303, the sliding groove 304, the sliding block 305, the clamping block 306, the anti-slip block 307, the threaded rod 308, the grip 309 and the fixed block 310, during use, the first bolt 302 is passed through the threaded hole formed on the surface of the support column 301 and the threaded hole formed on the surface of the workbench 1 and tightened and fixed. The grip 309 is rotated to drive the threaded rod 308 to rotate, so that the sliding block 305 moves along the sliding groove 304. The sliding groove 304 formed on the surface of the clamping table 303 provides guidance and limitation for the sliding of the sliding block 305, ensuring that the movement direction of the sliding block 305 is accurate and stable. The clamping block 306 gradually moves, and finally the hardware is tightly clamped between the two anti-slip blocks 307. The anti-slip block 307 can prevent the workpiece from slipping during the clamping process. The sliding block 305 can smoothly slide in the sliding groove 304, thereby driving the clamping block 306 to adjust its position. The anti-slip block 307 increases the friction between the clamping block 306 and the hardware, and can effectively prevent the article from slipping.

[0028] Furthermore, there are two sets of support columns 301, which are symmetrically arranged with respect to the central axis of the clamping table 303. With the arrangement of the two sets of support columns 301, during use, the symmetrical layout of the support columns 301 helps to improve the balance of the entire clamping mechanism 3. During the clamping operation, the position of the hardware may shift or uneven external forces may act on it. The symmetrical support structure can better resist these unstable factors, keeping the clamping table 303 always in a horizontal state, thereby ensuring the accuracy and reliability of the clamping.

[0029] Further, there are two sets of sliding grooves 304, which are symmetrically arranged with respect to the central axis of the clamping table 303. The inner wall size of the sliding groove 304 matches the outer wall size of the sliding block 305. Through the settings of the sliding groove 304 and the sliding block 305, during use, the movement of the clamping block 306 can be made more stable.

[0030] Further, there are two sets of anti-sliding blocks 307. One side surface of the anti-sliding block 307 is provided with anti-slip strips, and multiple groups of anti-slip strips are evenly distributed on the surface of the anti-sliding block 307. Through the setting of the anti-sliding block 307, during use, the two sets of anti-sliding blocks 307 can increase the contact area with the hardware part. The two sets of anti-sliding blocks 307 respectively provide frictional forces on both sides, thereby providing a larger contact area and further increasing the clamping stability.

[0031] Further, the lifting mechanism 4 includes a fixing plate 401, a lifting groove 402, a lifting block 403, a connecting block 404, a moving tooth block 405, a gear 406, a rotating shaft 407, a handle 408 and a supporting plate 409. The upper surface of the workbench 1 is fixedly connected with the fixing plate 401. The inner surface of the fixing plate 401 is provided with the lifting groove 402. The inner surface of the lifting groove 402 is slidably connected with the lifting block 403. The surface of the lifting block 403 is fixedly connected with the connecting block 404. One side surface of the connecting block 404 is fixedly connected with the moving tooth block 405. The outer surface of the moving tooth block 405 is engaged with the gear 406. The inner surface of the gear 406 is fixedly connected with the rotating shaft 407. One end of the rotating shaft 407 is fixedly connected with the handle 408. The upper surface of the workbench 1 is fixedly connected with the supporting plate 409. Through the settings of the fixing plate 401, the lifting groove 402, the lifting block 403, the connecting block 404, the moving tooth block 405, the gear 406, the rotating shaft 407, the handle 408 and the supporting plate 409, when it is necessary to raise the positioning mechanism 5, rotate the handle 408 to drive the rotating shaft 407 to rotate the gear 406. At the same time, the moving tooth block 405 drives the connecting block 404 to move upward, so as to raise the positioning mechanism 5. When the hardware part is placed, the handle 408 can be rotated in the reverse direction, so that the connecting block 404 drives the positioning mechanism 5 to move downward, thereby clamping the hardware part.

[0032] Further, there are two sets of lifting grooves 402 on the inner surface of the fixing plate 401. The inner wall size of the lifting groove 402 matches the outer size of the lifting block 403. Through the settings of the lifting groove 402 and the lifting block 403, during use, the close fit between the lifting block 403 and the lifting groove 402 can reduce the gap of the lifting block 403 in the lifting groove 402, can reduce the shaking and swinging amplitude of the lifting block 403 during movement, improve the lifting precision, and can also reduce the noise and wear generated due to the gap, and extend the service life of the lifting mechanism 4.

[0033] Furthermore, multiple groups of positioning blocks 501 are arranged on the outer surface of the positioning box 503, and are respectively distributed at the four corners of the positioning box 503. Through the arrangement of the positioning blocks 501, when in use, the multiple groups of positioning blocks 501 increase the number of contact points, thereby dispersing the pressure generated during positioning and improving durability and stability.

[0034] Furthermore, there are multiple groups of limiting holes 505 distributed at equal intervals on the surface of the limiting plate 504, and the inner wall size of the limiting hole 505 is consistent with the outer wall size of the positioning pin 508. Through the setting of the limiting hole 505 and the positioning pin 508, when in use, the limiting hole 505 and the positioning pin 508 fit tightly, which can prevent the positioning pin 508 from shaking in the limiting hole 505, thereby ensuring the accuracy and stability of positioning.

[0035] Working principle: first, turn the handle 408 to drive the rotating shaft 407 to rotate the gear 406, and at the same time, move the tooth block 405 to drive the connecting block 404 to move upward, so that the positioning mechanism 5 rises, put in the hardware, and the positioned hardware squeezes the positioning pin 508, and the clamping block 507 will compress the spring 506 to move backward, thereby providing a certain buffer and adaptation space for the positioning of the hardware. When the placement is completed, when the hardware is placed, the handle 408 can be rotated in the opposite direction, so that the connecting block 404 drives the positioning mechanism 5 to move downward, and the elastic force of the spring 506 will push the clamping block 507 and the positioning pin 508 to make them tightly against the hardware to achieve stable positioning. The limit plate 504 is fixed to the upper surface of the positioning box 503, and the limit hole 505 opened on the surface of the limit plate 504 is used to limit the movement range of the positioning pin 508 The clamping block 506 is used to clamp the hardware components 305 and the fixing block 307 to the fixing plate 308. The fixing block 506 is used to clamp the hardware components 305 and the fixing plate 308 to the fixing plate 308.
