[0002] A hook is a common lifting tool, usually made of solid metal materials such as steel or alloy; its shape is similar to a bent hook, with one end connected to the lifting equipment and the other end used to hang or lift objects; a hook usually has a strong load-bearing capacity and durability, and can be used to lift heavy objects, suspend objects or perform lifting operations; hooks are widely used in construction sites, factories, ports and other places to lift goods, mechanical equipment, building materials, etc.; the design and size of the hook can be customized according to specific needs to meet the use requirements of different occasions.

[0003] During the processing of the hook, one end of the hook handle needs to be turned into an outer circle and threaded. The existing processing of the hook is generally clamped by claws. When processing special-shaped hooks, the center of gravity of the hook is offset from the center of the hook handle. The hook installed on the lathe spindle cannot be dynamically balanced, which will cause the hook handle to be out of round when processing. Therefore, we propose a hook processing tooling to solve the above problems. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-7 A hook processing tooling comprises a tooling body 1, one side of which is fixedly provided with an installation shaft 10. When the hook processing tooling is used, the three-turn chuck on the main shaft of the lathe clamps the installation shaft 10, and then the hook processing tooling is installed on the main shaft of the lathe. A first clamping plate 4 and a second clamping plate 5 are slidably connected to the inner side of the tooling body 1. A first rack 8 is fixedly provided on one side of the first clamping plate 4, and the first rack 8 is rectangularly distributed on the side of the first clamping plate 4 close to the second clamping plate 5. A first T-shaped hole 11 is opened on one side of the tooling body 1, and the first T-shaped hole 11 is rectangularly distributed on one side of the tooling body 1. The first rack 8 is slidably connected to the inner side of the first T-shaped hole 11, and the teeth on one side of the first rack 8 do not contact the inner side of the first T-shaped hole 11. The first rack 8 fixedly arranged at the corner of one side of the clamping plate 4 is slidably connected to the inside of the first T-shaped hole 11, so that the first clamping plate 4 is slidably connected to the inner side of the tooling body 1, and a second rack 9 is fixedly arranged on one side of the second clamping plate 5, and the second rack 9 is rectangularly distributed on the side of the second clamping plate 5 away from the first clamping plate 4. A second T-shaped hole 12 is opened on one side of the tooling body 1, and the second T-shaped hole 12 is rectangularly distributed on one side of the tooling body 1, the second rack 9 is slidably connected to the inside of the second T-shaped hole 12, and the teeth on one side of the second rack 9 do not contact the inner side of the second T-shaped hole 12, and the second rack 9 fixedly arranged at the corner of one side of the second clamping plate 5 is slidably connected to the inside of the second T-shaped hole 12, so that the second clamping plate 5 is slidably connected to the inner side of the tooling body 1.

[0035] A support shaft 6 is inserted into the tooling body 1, and the support shaft 6 is located between the first rack 8 and the second rack 9. A gear 7 is sleeved on the outside of the support shaft 6, and the gear 7 can rotate on the outside of the support shaft 6. The gear 7 is sleeved on the outside of the support shaft 6, so that the gear 7 is rotatably connected to the inside of the tooling body 1, and the gear 7 is meshed with the first rack 8, and the gear 7 is meshed with the second rack 9. A threaded column 17 is rotatably connected to the middle of the side of the first clamping plate 4 away from the second clamping plate 5. A threaded hole 16 is opened on one side of the tooling body 1, which is rotatably connected to the first clamping plate 4. The threaded column 17 on one side is threadedly connected to the inside of the threaded hole 16. When the hook is used to process the tool, the threaded column 17 threadedly connected to the tool body 1 is rotated to move toward the inside of the tool body 1. The threaded column 17 drives the first clamping plate 4 slidably connected to the inside of the tool body 1 to move toward the middle of the tool body 1. At the same time, the first clamping plate 4 drives the first rack 8 fixed on one side thereof to move toward the outside of the tool body 1. The first rack 8 drives the gear 7 meshing with it to rotate, and the gear 7 drives the second rack 9 meshing with it. The hook is moved toward the inside of the tooling body 1, so that the second clamping plate 5 slidably connected to the inside of the tooling body 1 moves toward the middle of the tooling body 1, and the hook is clamped inside the tooling body 1. Since the gear 7 rotatably connected to the inside of the tooling body 1 is meshed with the first rack 8 and the second rack 9 at the same time, the movement distance of the first clamping plate 4 and the second clamping plate 5 is always equal, so that the hook is clamped between the first clamping plate 4 and the second clamping plate 5 in the center of the tooling body 1, that is, it is ensured that the symmetry plane of the hook passes through the axis of the lathe spindle. The outer side of the tool body 1 is threadedly connected with a positioning screw 2, and the positioning screw 2 passes through the tool body 1. The positioning screw 2 is threadedly connected to the upper and lower surfaces of the tool body 1. By turning the positioning screw 2, the hook clamped inside the tool body 1 is positioned so that the hook handle axis of the hook coincides with the lathe spindle. By setting an opposing mechanism composed of a gear 7, a first rack 8 and a second rack 9, the hook is clamped in the center position of the tool body 1, which is beneficial to increase the speed of clamping the hook when processing the hook handle and improve the processing efficiency of the hook.

[0036] A U-shaped limiting plate 13 is fixedly provided on one side of the tooling body 1, and a limiting column 14 is fixedly provided on one side of the first T-shaped hole 11. A plurality of dynamic balance adjustment plates 3 are provided on the inner side of the U-shaped limiting plate 13. A limiting hole 18 is provided in the middle of the upper surface of the dynamic balance adjustment plate 3, and the limiting column 14 is penetrated in the limiting hole 18. A nut 15 is threadedly connected to the upper part of the limiting column 14. By tightening the nut 15 threadedly connected to the upper part of the limiting column 14, the nut 15 abuts against one side of the stacked dynamic balance adjustment plates 3, thereby fixing the dynamic balance adjustment plates 3. It is fixedly installed inside the C-shaped limit plate 13. When using the hook processing tooling, by adjusting the number of dynamic balance adjustment plates 3 fixedly installed on the inner side of the C-shaped limit plate 13, and the opposing mechanism composed of the gear 7, the first rack 8 and the second rack 9 cooperates with the first clamping plate 4 and the second clamping plate 5 to clamp the hook in the center position, so that when the hook handle of the hook coincides with the lathe shaft, the whole formed by the hook and the hook processing tooling reaches dynamic balance, avoiding large radial circular runout when the hook rotates, thereby avoiding the situation of out-of-roundness when processing the hook handle.
