Description

Technical Field

[0001] The utility model relates to the field of metal processing clamping, in particular to a clamping assembly for metal part processing. Background Technique

[0002] Metal processing refers to the process of processing and forming metal materials through methods such as machining, hot working, and cold working. During the processing of metal parts, in order to facilitate the processing of workers, clamping components are usually used to fixedly clamp the metal parts to be processed to prevent the metal parts from sliding during the processing. The clamping assembly for metal part processing is a component used to fix and hold metal workpieces during the processing. The clamping assembly plays a crucial role in the metal part processing, which can ensure the stability and accuracy of the workpiece, and improve the processing efficiency and quality.

[0003] For manual operation of columnar metal processing, the existing clamping assemblies generally have a small contact area with the workpiece, cause relatively large damage to the surface of tubular workpieces, and the workpiece clamping is unstable, affecting the processing size and appearance of the workpiece. Therefore, we propose a clamping assembly for metal part processing.

[0004] The purpose of the utility model is to realize the clamping of metal workpieces by the relative movement between the fixture and the fixture locking structure through the screw rod movement structure. Content of the Utility Model

The fixture includes clip pieces, inclined clip pieces, a clip piece base, and a clip piece connection ring. One surface of the clip piece base is fixedly connected with the clip piece connection ring. The other end of the clip piece connection ring is fixedly connected with six inclined clip pieces in an inclined manner. The six inclined clip pieces are evenly distributed in a circumferential manner. The other ends of the inclined clip pieces are fixedly connected with six clip pieces.

Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-5 , a clamping assembly for metal part processing, including a mounting table 3, a fixture, a fixture locking structure and a lead screw structure. Four mounting connection holes 4 are respectively penetrated through the four corners of the mounting table 3. One surface of the mounting table 3 is fixedly connected with the fixture locking structure. A fixture is arranged inside the fixture locking structure. One end of the base of the fixture passes through the mounting table 3 and is fixedly connected with one end of the lead screw structure. The fixture includes a collet 1, an inclined collet 10, a collet base 12 and a collet connection ring 13. One surface of the collet base 12 is fixedly connected with the collet connection ring 13. The other end of the collet connection ring 13 is inclined and fixedly connected with six inclined collets 10. The six inclined collets 10 are evenly distributed in a circle. The other end is fixedly connected with six collets 1. Each inclined collet 10 corresponds to each collet 1. The inclined collet 10 is made of a high-strength and high-toughness material that can undergo plastic deformation. During processing and installation, the connection strength between the inclined collet 10 and the collet connection ring 13 is ensured.

[0025] Further, on one inner surface of the collet 1, silicone rubber is fixedly connected to the collet 1. The silicone rubber 14 is made of a material with high friction and wear resistance. When connected to the workpiece, it keeps the clamping stable and does not wear the workpiece.

[0026] Further, the fixture locking structure includes a locking housing 2 and a locking conical tube 11. One surface of the mounting table 3 is fixedly connected with the locking housing 2. The locking conical tube 11 is an irregular conical tube with a large diameter at one end and a small diameter at the other end. The small-diameter end of the locking conical tube 11 is fixedly connected to the inside of the locking housing 2 and on one surface of the mounting table 3. The irregular shape of the locking conical tube 11 makes the clamping a variable process when the fixture moves inward.

[0027] Further, the lead screw structure includes a leg 5, a support plate 7, a lead screw 8, a handle 9, and a threaded hole 16. On the opposite side of the mounting table 3 fixedly connected to the fixture locking structure, the leg 5 is fixedly connected. The other end of the leg 5 is fixedly connected to the support plate 7. A threaded hole 16 is provided at the center of the support plate 7. One end of the lead screw 8 passes through the threaded hole 16 and is fixedly connected to the clip base 12. The other end of the lead screw 8 is fixedly connected to the handle 9. When the lead screw 8 is rotated, the threaded hole 16 enables the lead screw 8 to move left and right relative to the support plate 7, thereby realizing the relative movement of the fixture.

[0028] Further, between the support plate 7 and the clip base 12, a nut 6 is coaxially connected to the lead screw 8. Between the support plate 7 and the handle 9, a left-handed nut 15 is coaxially connected to the lead screw 8. The thread directions of the nut 6 and the left-handed nut 15 are different. When the support plate 7 is rotated and clamped, vibrations generated during metal workpiece processing may cause the fixture to loosen. The nut 6 and the left-handed nut 15 have an effect of limiting and locking the support plate 7.

[0029] Working principle: The mounting table 3 of the clamping assembly is bolted and installed on the metal processing workbench. During use, the workpiece is placed between the clips 1. Rotating the handle 9 drives the support plate 7 to move the fixture relative to the locking conical tube 11 into the locking conical tube 11. According to the structure of the locking conical tube 11, the inclined clips 10 contract inward, thereby clamping the workpiece. Rotating the nut 6 and the left-handed nut 15 moves them toward the support plate 7 to lock the lead screw structure. After the metal workpiece processing is completed, rotating the nut 6 and the left-handed nut 15 loosens the support plate 7, and rotating the handle 9 in the other thread direction moves the fixture out of the locking conical tube 11, thereby loosening the workpiece after processing and taking out the workpiece.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
