Description

Technical Field

[0001] The utility model relates to the technical field of hardware tool processing, in particular to a fixing device for pliers processing. Background Art

[0002] Pliers are tools used to clamp, hold or pull objects, or to cut something. They are usually V-shaped and usually consist of three main parts: handles, jaws and jaws. Fixtures used for pliers processing are usually called fixtures. Fixtures are mechanical devices used to fix workpieces for processing or assembly. They provide stable support and positioning, allowing the pliers to maintain accurate position and posture during processing.

[0003] After searching, the utility model patent with the publication number CN216399027U discloses a fixed tooling for pliers grinding equipment, including a workbench, a fixing mechanism, a grinding mechanism and a controller. A vertical plate is vertically fixed on the top right side of the workbench, and the grinding mechanism is fixed on the left side of the vertical plate. The fixing mechanism includes a circular turntable and a plurality of fixing components uniformly fixed on the top of the circular turntable along the circumferential direction. The bottom of the circular turntable is connected to the top of the workbench through a first rotating component. The fixing component includes a fixing block and a lifting plate. The bottom end of the fixing block is connected to the top of the lifting plate through a second rotating component. The bottom of the lifting plate is connected to the circular turntable through a first telescopic component. A first groove is downwardly arranged on the top of the fixing block, and a second groove is downwardly arranged on the right side of the bottom of the first groove. The left side wall of the first groove is connected to a fixing rod through an electric telescopic rod.

[0004] However, in the implementation of the relevant technology, it was found that the following problems exist: the fixing tool of the existing pliers grinding equipment can fix the pliers mouth by turning on the electric telescopic rod until the fixing rod fixes the bottom end of the pliers mouth, but this method requires starting multiple electric telescopic rods at the same time. The starting of multiple electric telescopic rods may cause uneven fixing force, so that some parts of the pliers mouth may be over-fixed, while other parts may not reach sufficient fixing force. Therefore, a fixing device for pliers processing is needed. Utility Model Content

[0023] See also Figures 1 to 4 The utility model provides a technical solution for a fixing device for processing pliers: a fixing device for processing pliers, comprising a circular turntable 1 and a plurality of grooves 11 equidistantly arranged in an annular shape on the top of the circular turntable 1, two fixing plates 4 are symmetrically arranged inside the plurality of grooves 11, and a protective layer is fixedly connected to the opposite sides of the two fixing plates 4, and the material of the protective layer can be rubber or foam material, and the rubber has good compression resistance, wear resistance and elasticity, and can effectively buffer and absorb external impact force, and protect the contact surface of the pliers, and the foam material can provide a soft buffering effect, protect the contact surface of the pliers, and has the characteristics of shock absorption and sound insulation, and is used to protect the contact surface of the pliers, and the inner wall of the circular turntable 1 is provided with an installation cavity;

[0024] The interior of the installation cavity is provided with a driving mechanism 2 and a positioning mechanism 3 which is driven by the driving mechanism 2 to simultaneously move two fixing plates 4 in a plurality of grooves 11 relative to each other to fix the pliers.

[0025] Specifically, the driving mechanism 2 includes a motor 21, which is fixed to the inner bottom wall of the installation cavity. The output end of the motor 21 is fixedly connected to a rotating shaft 22, and the top of the rotating shaft 22 is fixedly connected to a large bevel gear 23. The top of the large bevel gear 23 is meshed with a plurality of small bevel gears 24. The bottom of the large bevel gear 23 is symmetrically fixedly connected to two vertical rods 5, and the bottom ends of the two vertical rods 5 are sleeved with buffer beads 51. The inner bottom wall of the installation cavity is provided with an annular groove 52 for the buffer beads 51 to slide, and the inner cavity of the annular groove 52 is semicircular. The top of the large bevel gear 23 is meshed with a plurality of small bevel gears 2. Starting the motor 21 drives the rotating shaft 22 to rotate at the output end, and the rotation of the rotating shaft 22 drives the large bevel gear 23 to rotate and mesh with the plurality of small bevel gears 24. When the large bevel gear 23 rotates, a buffer bead 51 is arranged at its bottom, and the sliding of the buffer bead 51 in the annular groove 52 can play a role of shock absorption, and can reduce the impact force caused by the suspension of the rotation of the large bevel gear 23. To a certain extent, the buffer bead 51 can reduce the excessive fixation of the fixed plate 4 on the pliers.

[0026] More specifically, the positioning mechanism 3 includes a plurality of bidirectional threaded screws 31, both ends of which are rotatably connected to the inner wall of the installation cavity, and the plurality of bidirectional threaded screws 31 are respectively fixed to the inner walls of a plurality of small bevel gears 24, and the outer walls of the plurality of bidirectional threaded screws 31 are threadedly connected to two displacement blocks 32, and the tops of the two displacement blocks 32 are fixedly connected to a spacer block 33, and the bottom of the groove 11 is provided with a rectangular groove 111 for the spacer block 33 to slide left and right, and the rectangular groove 111 is connected to the interior of the installation cavity, and the fixing plate 4 is fixed to the top of the spacer block 33. The rotation of the plurality of small bevel gears 24 drives the plurality of bidirectional threaded screws 31 to rotate, so that the two displacement blocks 32 move relative to each other on the outer walls of the plurality of bidirectional threaded screws 31, so that the fixing plate 4 on the top of the spacer block 33 gradually approaches until the bottom end of the pliers mouth is fixed, so that the simultaneous fixing of multiple pliers mouths can be completed, which can help ensure that multiple pliers mouths are fixed at the same time and are evenly stressed during the fixing process, so that the fixing result is more balanced and stable.
