Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to a clamp for high-precision hardware processing. Background Art

[0002] Precision hardware specifically refers to the hardware processing category with higher precision requirements in the hardware industry. During the processing of precision hardware, it is often necessary to use a clamp to clamp the workpiece. The existing clamp usually has two symmetrical clamps on the processing table, and uses two clamps to clamp the workpiece from both sides. However, this type of clamp is more suitable for workpieces with relatively regular shapes, such as square workpieces. When facing irregularly shaped workpieces, especially bent hardware such as L-shaped hexagonal screwdrivers and angle steels, due to the special shape of the bent workpiece, simply relying on two clamps to clamp from both sides is prone to problems such as workpiece deflection and loosening, resulting in unstable clamping effect, affecting subsequent processing accuracy and product quality.

[0019] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0020] Existing clamps usually use two clamps to clamp the workpiece from both sides. When facing irregularly shaped workpieces, especially bent hardware such as L-shaped hexagonal screwdrivers and angle steels, this type of clamp is prone to problems such as workpiece deflection and loosening when simply relying on two clamps to clamp from both sides, resulting in unstable clamping effect, affecting subsequent processing accuracy and product quality.

[0021] To solve the defects of the above fixture when clamping the bent workpiece, please refer to Figures 1-4 The utility model provides a high-precision hardware processing fixture, which can perform targeted clamping on bent workpieces and improve the stability of bent workpieces during processing. The fixture is based on a processing table 1. A pillar 2 is fixedly installed on the top of the processing table 1. Two steering rods 3 are provided on the outer rotating sleeve of the pillar 2, and a locking cap 7 is threadedly installed on the top of the pillar 2. The locking cap 7 is used to lock the two steering rods 3. The outer side of the steering rod 3 is slidably connected to a translation seat 4. A rotating shaft 5 is rotatably installed at the center position of the top of the translation seat 4. A clamping member 6 is provided on the top of the rotating shaft 5. The clamping member 6 is used to clamp the bent workpiece. The two clamping members 6 can be fixed from both ends of the workpiece respectively. A limiting member 8 is provided on one side of the top of the translation seat 4. The limiting member 8 is used to fix the rotating shaft 5. Due to different working The bending angles of the workpiece are different. The two steering rods 3 can be rotated to the angle corresponding to the workpiece, and then the locking caps 7 are tightened to fix the two steering rods 3. Then the sliding seat 4 drives the clamping parts 6 to slide, and the two clamping parts 6 are slid to correspond to the two ends of the workpiece. Then the clamping parts 6 are rotated to align the clamping parts 6 with the extension direction of the workpiece, and then the two ends of the bent workpiece can be placed in the two clamping parts 6 respectively, and then the clamping parts 6 are fixed and placed by the limit parts 8. The clamping parts 6 rotate automatically, and finally the clamping parts 6 are driven to clamp the two ends of the workpiece, so that stable clamping of the bent workpiece can be achieved, which is suitable for workpieces with different bending angles.

[0022] In order to prevent the clamping member 6 from rotating automatically, refer to Figure 3The limit block 84 can limit the rotation of the rotating shaft 5, thereby preventing the clamping member 6 from rotating, thereby enhancing the stability of the workpiece on the clamping member 6.

[0023] Since the lengths of different bending workpieces may be different, in order to ensure that both ends of the workpiece can fall into the two clamping members 6, an insertion rod 10 is inserted into the interior of the translation seat 4, and one end of the insertion rod 10 passes through the translation seat 4 and is threadedly installed with an anti-slip cap 11. A plurality of slots 9 for inserting the insertion rod 10 are provided on the steering rod 3, and the plurality of slots 9 are distributed equidistantly laterally. When adjusting the position of the clamping member 6, the translation seat 4 can be pulled to slide on the steering rod 3. When the clamping member 6 is adjusted to the specified position, the insertion rod 10 is inserted into the translation seat 4, and the insertion rod 10 can pass through the corresponding slot 9. Then the anti-slip cap 11 is tightened on the insertion rod 10, which can fix the translation seat 4 and prevent the translation seat 4 from automatically sliding on the steering rod 3, so as to achieve stable clamping of bent workpieces of different specifications by the equipment.

[0024] In order to achieve the clamping effect of the above-mentioned clamping member 6 on the workpiece, the clamping member 6 is set to a clamping seat 61 fixedly installed on the upper end of the rotating shaft 5, and threaded rods 62 are threadedly installed on both sides of the clamping seat 61. The ends of the threaded rods 62 are rotatably connected to the clamping plates 63, and the bottom of the clamping plates 63 are slidably connected to the inner bottom wall of the clamping seat 61. After the above-mentioned adjustment of the position and angle of the clamping member 6, the workpiece can fall into the clamping seat 61, and then the threaded rod 62 is rotated to push the clamping plates 63 to slide. The two clamping plates 63 slide toward the workpiece to clamp the workpiece, thereby achieving fixation of the workpiece.
