Description

Technical Field

[0001] The utility model relates to the technical field of metal connectors, in particular to a clamping workbench for metal connector processing with an adjustable processing surface. Background Art

[0002] The existing clamping and fixing device is difficult to adjust after clamping and fixing the metal connector. If the angle of the metal connector needs to be changed, the metal connector needs to be clamped and fixed again, which is a complicated operation.

[0003] In order to solve the above problem, there is a solution for a clamping device for processing a metal connector that is easy to adjust the angle (Announcement No. CN217668490U), in which the two clamping blocks are driven to move in opposite directions by a driving component, and the metal connector is placed between the two clamping blocks. The two clamping blocks are then driven to move in relative directions by the driving component to clamp and fix the metal connector; when the angle of the metal connector needs to be adjusted, the shell is driven by the adjustment component, and the metal connector located on the upper surface of the shell is rotated to a preset angle.

[0004] However, the above solution uses the elastic force of the spring to control the two clamping blocks to clamp the metal connector, but the stability of the spring clamping is insufficient. When the metal connector is cut and polished, the metal connector is easy to loosen, and it is difficult to ensure the processing accuracy. Utility Model Content

[0005] The utility model aims to provide a clamping workbench for metal connector processing with an adjustable processing surface, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping workbench for metal connector processing with adjustable processing surface, comprising an assembly plate, a bracket rotatably connected to the surface of the assembly plate, a threaded barrel fixedly connected to the upper end of the bracket, and a stud screwed inside the threaded barrel, a fixed column connected to the upper end of the stud, and a push-pull sleeve and a limit ring sleeved on the fixed column;

[0007] The bracket can rotate, thereby enabling the chuck to rotate. When the chuck clamps the metal connector, the metal connector can also rotate, so that the metal connector can be processed in a circular manner.

[0008] An extension arm, wherein two extension arms are arranged and fixedly connected to the surface of the threaded barrel, a transmission rod is rotatably connected to the surface of the extension arm, a chuck is rotatably connected to the upper end of the transmission rod, a control rod is rotatably connected between the push-pull sleeve and the transmission rod, and the rotation of the stud can drive the control rod to open or close, thereby controlling the distance between the two chucks and tightening the metal connector.

[0009] Furthermore, a plurality of rotating handles are fixedly connected to the surface of the threaded barrel, and the rotating handles can be used to manually control the rotation of the metal connector, so that the metal connector can be processed more flexibly.

[0010] Furthermore, a screwing ring is fixedly connected to the lower end of the stud, and using the screwing ring saves effort when screwing the stud, and the operation of clamping and releasing the metal connector is more convenient.

[0011] Furthermore, a bearing is installed inside the assembly plate, and the bracket is fixedly connected to the inner ring of the bearing, so that the flexibility of the chuck rotation is improved by the bearing. A gear ring is fixedly connected to the surface of the bracket, and the rotation of the chuck can be automatically controlled by using a motor and a gear.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The stud is rotated by twisting the ring, and the stud moves in the threaded barrel. The control rod is used to drive the corresponding transmission rod to rotate. The transmission rod controls the chuck to clamp the metal connector, which makes the metal connector more stable. When the metal connector is cut, the metal connector will not deviate, thereby improving the processing accuracy of the metal connector.

[0014] (2) The rotation of the clamped metal connector can be manually controlled by the rotating handle, so that the metal connector can be processed locally in detail. The rotation of the metal connector can be automatically controlled by the motor and gear, so that the metal connector can be processed comprehensively. The combination of manual and automatic can make the metal connector more flexible. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] An extension arm 14 is provided with two extension arms 14 and fixedly connected to the surface of the threaded tube 5. A transmission rod 15 is rotatably connected to the surface of the extension arm 14. A chuck 12 is rotatably connected to the upper end of the transmission rod 15. A control rod 11 is rotatably connected between the push-pull sleeve 10 and the transmission rod 15. When the fixed column 9 moves up and down, the transmission rod 15 can be opened or pulled by the control rod 11, so that the transmission rod 15 can control the opening and closing of the chuck 12.

[0025] In this embodiment, if Figure 1 As shown, a plurality of rotating handles 6 are fixedly connected to the surface of the threaded barrel 5. The plurality of rotating handles 6 facilitates manual and continuous control of the rotation of the threaded barrel 5.
