Description

Technical Field

[0001] This utility model relates to the field of metal forging processing technology, and more specifically, to a clamping device for metal forging processing. Background Technology

[0002] Metal forgings are produced by processing metal billets through forging, causing plastic deformation to obtain workpieces or blanks with specific mechanical properties, shapes, and dimensions. This process eliminates casting defects such as porosity, optimizes the microstructure, and preserves intact metal flow lines, resulting in forgings typically exhibiting superior mechanical properties compared to castings of the same material. However, when drilling holes in metal forgings, clamping equipment is required for secure fixing.

[0003] There are many types of existing metal forgings. When machining racks and gears, clamping equipment is required. This equipment often uses a plate-like structure to hold the metal forgings on both sides. However, metal forgings come in various shapes, and many have smooth protrusions. When clamping these forgings with a plate-like structure, only the most prominent protrusions are contacted, which can easily lead to shaking and slippage during machining. Therefore, we propose a clamping device for machining metal forgings. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a clamping device for metal forging processing, so as to solve the technical problem that the current equipment is not stable enough when clamping metal forgings with smooth protrusions.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a clamping device for metal forging processing, comprising a cabinet installed on both sides of a panel and a motor installed inside the cabinet. The output end of the motor is fixedly connected to a worm gear, and the other end of the worm gear is rotatably connected to the inner wall of the cabinet. The worm gear is meshed with multiple worm wheels, and a screw is fixedly connected through the center of each worm wheel. One end of the screw is rotatably connected to the inner wall of the cabinet. The screw is meshed with a threaded sleeve through an external thread groove. A mounting block is fixedly connected to both the top and bottom ends of the threaded sleeve. One end of the mounting block is fixedly connected to an elastically telescopic clamping structure, and the other end of the clamping structure extends to the outside of the cabinet. The multiple clamping structures are arranged in two parallel groups on the upper and lower parts of one side wall of the outside of the cabinet, and each group of clamping structures is evenly distributed on a horizontal plane.

[0006] Preferably, a guide block is connected to one side of the screw sleeve, the guide block is provided with a guide hole that passes through both sides, a guide rod is inserted into the guide hole, and one end of the guide rod is fixedly connected to the inner wall of the cabinet.

[0007] Preferably, the clamping structure includes a connecting rod and a clamping rod. One end of the connecting rod is fixedly connected to the mounting block. The clamping rod has a cavity inside, and one end of the clamping rod is sleeved on the other end of the connecting rod through the cavity. The other end of the clamping rod extends through to the outside of the cabinet.

[0008] Preferably, the clamping structure further includes a spring connected between the other end of the clamping rod and the connecting rod.

[0009] Preferably, the end of the clamping rod is provided with a clamping claw, which is composed of three identical claws, and the three claws are arranged in a ring at equal intervals at the end of the clamping rod. Each claw is a cuboid structure with a sloping surface on one side, and the width of the face of the claw away from the clamping rod is smaller than the width of the face of the sloping surface near the clamping rod. The sloping surface is located near the center of the end of the clamping rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model features multiple elastically extendable clamping structures at various points, driven simultaneously by a drive component consisting of a motor, worm gear, worm wheel, screw, and screw sleeve. These multiple clamping structures press against various positions on the upper and lower parts of the metal forging, simultaneously providing clamping and partial locking effects. With this utility model, the metal forging is less prone to shaking or slipping after being fixed.

[0012] 2. Existing clamping structures use flat or round heads, which cannot effectively fix metal forgings with toothed grooves because they can only contact the outer wall of the grooves. This invention addresses this by setting clamping claws at the end of the clamping rod. The inclined structure of the three claws is inserted into the toothed grooves on the surface of the metal forging to form a fixation, which acts as a locking mechanism. Furthermore, the insertion of multiple clamping claws into various parts of the metal forging makes it more difficult for the metal forging to move, thus optimizing the fixing effect on the forging.

[0021] like Figures 1 to 7 As shown, this utility model relates to a clamping device for processing metal forgings, comprising a cabinet 101 mounted on both sides of a panel 1 and a motor 2 mounted inside the cabinet 101. The output end of the motor 2 is connected to a worm gear 201 via a coupling, and the other end of the worm gear 201 is rotatably connected to the inner wall of the cabinet 101. The worm gear 201 is meshed with five worm wheels 3, and a screw 301 is bolted through the center of each worm wheel 3. One end of the screw 301 is connected to the cabinet 101. The inner wall is rotatably connected, and the screw 301 is engaged with the screw sleeve 302 through the external thread groove. The top and bottom ends of the screw sleeve 302 are both bolted to the mounting block 303. One end of the mounting block 303 is bolted to the elastically telescopic clamping structure 4, and the other end of the clamping structure 4 extends through to the outside of the cabinet 101. Multiple clamping structures 4 are arranged in two parallel groups on the upper and lower parts of one side wall of the outside of the cabinet 101, and each group of clamping structures 4 is evenly distributed on the horizontal plane. This utility model sets multiple elastically telescopic clamping structures 4 at multiple points, and drives them simultaneously through a driving component composed of motor 2, worm 201, worm wheel 3, screw 301 and screw sleeve 302. Multiple clamping structures 4 are pressed against various positions on the upper and lower parts of the metal forging, simultaneously achieving the effects of clamping and partial locking, making it less likely for the metal forging to shake after being fixed.

[0022] In embodiments of this utility model, to keep the screw sleeve 302 moving in a straight line, such as... Figure 4As shown, this utility model discloses the specific structure of the guide block 304. The guide block 304 is bolted to one side of the threaded sleeve 302. The guide block 304 has guide holes 305 penetrating both sides. A guide rod 306 is inserted into the guide holes 305, and one end of the guide rod 306 is bolted to the inner wall of the cabinet 101. When the threaded sleeve 302 moves, the guide block 304 moves accordingly. Simultaneously, the guide rod 306 provides a channel for the guide holes 305 to move, ensuring that the guide block 304 can only move linearly along the guide rod 306. Therefore, while restricting the rotation of the threaded sleeve 302, the threaded sleeve 302 moves linearly along the direction of the guide rod 306, ensuring the linear movement of the clamping structure 4 and preventing damage to the metal forging from the oblique clamping structure 4.

[0023] As another embodiment of this utility model, to understand how the clamping structure 4 elastically expands and contracts, as follows: Figure 5 As shown, this utility model discloses the specific structure of the clamping structure 4. The clamping structure 4 includes a connecting rod 401 and a clamping rod 402. One end of the connecting rod 401 is bolted to the mounting block 303. The clamping rod 402 has a cavity inside, and one end of the clamping rod 402 is sleeved on the other end of the connecting rod 401 through the cavity. The other end of the clamping rod 402 extends through the outside of the cabinet 101. The clamping structure 4 also includes a spring 403, which is welded between the clamping rod 402 and the other end of the connecting rod 401. In this utility model, the clamping rod 402 slides on one end of the connecting rod 401 through the cavity. The spring 403 pushes the clamping rod 402 to return to its original position after movement. When the clamping rod 402 contacts the metal forging, the spring 403 is compressed, and the clamping rod 402 slides on the connecting rod 401 as a buffer, thereby avoiding the situation where the clamping rod 402 is too rigid when in contact with the metal forging, which could lead to damage to the metal forging.

[0024] It is worth noting that the clamping rod 402 has a clamping claw 404 at its end. The clamping claw 404 consists of three identical claws, which are equidistantly arranged in a ring at the end of the clamping rod 402. Each claw is a cuboid structure with a bevel 405 on one side, and the width of the face of the claw away from the clamping rod 402 is smaller than the width of the face of the bevel 405 near the clamping rod 402. The bevel 405 is located near the center of the end of the clamping rod 402. Figure 6 and Figure 7As shown, the existing clamping structure has a flat or round head at one end. When facing a metal forging with toothed grooves, it can only contact the outer wall of the toothed groove, which cannot play a good role in fixing it. This utility model sets a clamping claw 404 at the end of the clamping rod 402. The inclined surface 405 of the three claws is inserted into the toothed groove on the surface of the metal forging to form a fixation, which plays a locking role in the toothed groove. Furthermore, by inserting multiple clamping claws 404 into various parts of the metal forging, the metal forging is more difficult to shake, thus optimizing the fixing effect of the forging.

[0025] Working Principle: This embodiment provides a clamping device for metal forging processing. During use, turning on motor 2 drives worm gear 201 to rotate, which in turn drives worm wheel 3 to rotate. Worm wheel 3 then drives screw 301 to rotate. Screw 301 applies rotational force to threaded sleeve 302. Threaded sleeve 302 rotates along guide rod 306 through guide hole 305 on guide block 304, converting the rotational force into linear motion force. Threaded sleeve 302 slides along screw 301, driving connecting rod... When 401 moves, the connecting rod 401 drives the clamping rod 402 to move via the spring 403. The clamping rod 402 presses against the metal forging. Upon contact, the spring 403 is compressed, and the clamping rod 402 slides through the cavity at one end of the connecting rod 401 for buffering. The clamping rod 402, which is in close contact with the metal forging, drives the clamping claw 404 to clamp the metal forging. The three claws of the clamping claw 404 are inserted into the tooth grooves or keys on the surface of the metal forging via the inclined surface 405 to fix the metal forging.

[0026] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
