Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing jigs, and particularly relates to a hardware processing jig. Background Art

[0002] Hardware refers to various metal devices made of metals such as gold, silver, copper, iron, and tin through processing, casting, forging, etc. Hardware has a wide range of applications in many fields such as daily life, construction, machinery manufacturing, and electronic equipment. Its quality and performance have an important impact on the stability and reliability of related products.

[0003] The existing Chinese patent: A hardware processing jig, patent number: CN221390736U, includes an operating table. Two sliding grooves I are opened on the upper surface of the operating table. Two support frames are arranged above the operating table. A connecting plate is fixedly connected to the inner wall of each support frame. Springs arranged at equal distances are fixedly connected to the outer surface of each connecting plate. An activity plate is arranged above each support frame. By setting components such as support frames, connecting plates, and springs, the corresponding support frame is driven to move through a fixed block. The support frame drives the connecting plate to move. At the same time, the connecting plate drives the spring and the activity plate to move synchronously. The activity plate and the anti-slip sleeve are in contact with the hardware, and the activity plate compresses the corresponding spring. At the same time, the activity plate drives the H-shaped plate to slide on the inner wall of the limit groove I, so that the hardware is surrounded and clamped by the activity plate, thereby achieving the effect that the device can clamp hardware with various shapes and adaptively clamp.

[0004] However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: The above processing jig compresses the spring through the activity plate so that it can clamp irregular metal parts. When processing the hardware, if the force application direction is the same as the spring compression direction, the spring will be compressed, and then the activity plate will be separated from the workpiece, resulting in the hardware not being clamped tightly, and the clamping stability is poor.

[0024] In the embodiments of the present application, by providing a fixture for processing hardware parts, the technical problem that the above-mentioned fixture compresses the spring through the movable plate so that it can clamp irregular metal parts, and when processing the hardware parts, if the force application direction is consistent with the spring compression direction, the spring will be compressed, and then the movable plate will be separated from the workpiece, resulting in the inability to clamp the hardware parts and poor clamping stability is effectively solved. By rotating the support table for angle adjustment, and then rotating the first unidirectional threaded rod to make the second snap ring clamp the first snap ring to fix the support table, the effect of being able to adjust the angle according to the processing requirements is achieved. By rotating the clamping plate to complete the locking and unlocking of the clamping rod, the clamping rod can have two states of sliding and fixing. Even if a force is applied to the hardware part along the spring compression direction during processing after the clamping rod clamps the hardware part, the clamping rod will not slide, achieving the effect of improving the clamping stability.

[0025] Embodiment

[0026] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 And Figure 7As shown, the technical solution in the embodiment of the present application effectively solves the above technical problem that the processing fixture compresses the spring through the movable plate so that it can clamp irregular metal parts. When processing hardware parts, if the force application direction is consistent with the spring compression direction, the spring will be compressed, and then the movable plate will disengage from the workpiece, resulting in the hardware parts not being clamped tightly and the clamping stability being poor. The general idea is as follows:

[0027] In view of the problems existing in the prior art, the present utility model provides a hardware part processing fixture, which includes a support table 1. A bidirectional threaded rod 9 is rotatably installed on the support table 1. Clamping mechanisms are symmetrically and slidably installed on the support table 1. The clamping mechanisms include sliding seats 2, clamping rods 3, first springs 4, locking rods 5, clamping plates 6, second springs 7 and transmission rods 8. The two sliding seats 2 are threadedly connected to the two ends of the bidirectional threaded rod 9. The sliding seats 2 are slidably installed on the support table 1. A plurality of clamping rods 3 are slidably installed inside the sliding seats 2. The first springs 4 are fixedly installed at the side ends of the clamping rods 3. The two locking rods 5 are symmetrically and rotatably installed at the side ends of the sliding seats 2.

[0028] A plurality of bayonets are symmetrically formed on the clamping rods 3. A rubber pad is fixedly installed at the side end of the clamping rod 3. A plurality of bumps on the sliding seat 2 correspond to the bayonets of the clamping rods 3. The clamping plate 6 is slidably installed inside the sliding seat 2. The two second springs 7 are symmetrically fixedly installed between the clamping plate 6 and the sliding seat 2. The pull rod of the clamping plate 6 passes through the sliding seat 2 and protrudes. A card slot is formed on the contact surface between the side end of the locking rod 5 and the sliding seat 2. A clamping block on the clamping plate 6 corresponds to it.

[0029] The transmission rod 8 is rotatably installed inside the sliding seat 2. The transmission rod 8 drives the two locking rods 5 to rotate through bevel gears. A knob is fixedly installed on the transmission rod 8. An opening is formed on the sliding seat 2 to expose the knob. A fixing plate 11 is rotatably installed at the bottom end of the support table 1. A first snap ring 12 is fixedly installed on the support table 1. A first one-way threaded rod 14 is rotatably installed on the fixing plate 11. A second snap ring 13 is slidably installed on the fixing plate 11. The second snap ring 13 is threadedly connected to the first one-way threaded rod 14. A clamping plate 16 is slidably installed on the fixing plate 11. A second one-way threaded rod 15 is rotatably installed on the fixing plate 11. The second one-way threaded rod 15 is threadedly connected to the clamping plate 16.

[0030] Working principle:

[0031] First step, when in use, place the lower part of the fixed plate 11 above the tabletop, and rotate the second one-way threaded rod 15 counterclockwise. Since the second one-way threaded rod 15 is threadedly connected to the clamping plate 16, rotating the second one-way threaded rod 15 counterclockwise will cause the clamping plate 16 to slide upward, so that the clamping plate 16 and the second one-way threaded rod 15 clamp the tabletop from the upper and lower ends. Rotate the turntable 1 according to the required angle for processing, so that the turntable 1 rotates around the side end of the fixed plate 11. When the turntable 1 rotates to the required angle, rotate the first one-way threaded rod 14 counterclockwise. Since the first one-way threaded rod 14 is threadedly connected to the second clamping ring 13, rotating the first one-way threaded rod 14 counterclockwise will cause the second clamping ring 13 to slide towards the first clamping ring 12 until the second clamping ring 13 is completely fitted with the first clamping ring 12. The second clamping ring 13 will clamp the first clamping ring 12 to fix the turntable 1. By rotating the turntable 1 for angle adjustment and then rotating the first one-way threaded rod 14 to make the second clamping ring 13 clamp the first clamping ring 12 to fix the turntable 1, the effect of being able to adjust the angle according to the processing requirements is achieved.

[0032] Second step, in the initial state, the side ends of the clamping rods 3 are in the same plane. The two locking rods 5 clamp all the clamping rods 3 from the upper and lower directions. After fixing the support table 1, place the hardware to be processed between the two sliding seats 2. If the shape of the hardware is a regular square, rotate the bidirectional threaded rod 9 clockwise. Since the two sliding seats 2 are threadedly connected to the two ends of the bidirectional threaded rod 9, rotating the bidirectional threaded rod 9 clockwise will cause the two sliding seats 2 to slide inward simultaneously, so that the clamping rods 3 at both ends clamp the two ends of the hardware. Since the clamping rods 3 are clamped by the two locking rods 5, the clamping rods 3 will not slide. If the hardware to be processed is irregular, first pull the clamping plate 6 outward, so that the clamping plate 6 leaves the side end of the locking rod 5 against the elastic force of the second spring 7. During this process, if the rotation angle of the locking rod 5 does not reach a multiple of 90 degrees, the bayonet of the locking rod 5 will not correspond to the block of the clamping plate 6. Then rotate the knob on the transmission rod 8 clockwise, and the transmission rod 8 will simultaneously rotate the two locking rods 5 through the bevel gears. The rotation of the two locking rods 5 will cause them to disengage from the clamping rods 3. Then rotate the bidirectional threaded rod 9 to make the sliding seats 2 slide inward, so that the clamping rods 3 contact the hardware. At this time, the clamping rod 3 that first contacts the hardware will compress the first spring 4 at its side end after being resisted, and the remaining clamping rods 3 will continue to slide under the push of the sliding seats 2 and the first spring 4 until they contact the hardware. After all the clamping rods 3 clamp the hardware, rotate the transmission rod 8 counterclockwise to drive the two locking rods 5 to reverse and reset to clamp all the clamping rods 3 and fix the positions of all the clamping rods 3. After the locking rods 5 are reset, the clamping plate 6 will reset and clamp the locking rods 5 under the elastic force of the two second springs 7. By rotating the clamping plate 6, the locking and unlocking of the clamping rods 3 are completed, so that the clamping rods 3 can have two states of sliding and fixing. After the clamping rods 3 clamp the hardware and are locked by the locking rods 5, even if force is applied to the hardware in the spring compression direction during processing, the clamping rods 3 will not slide, achieving the effect of improving the clamping stability.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
