Description

Technical Field

[0001] This utility model relates to the field of metal clamping carriers, specifically a metal clamping carrier with a thin-walled shell that is resistant to deformation. Background Technology

[0002] Metal clamping carriers are key functional components of metal clamping tools (or fixtures). Their main function is to effectively fix, position, and transmit force on metal workpieces (such as metal wires, metal sheets, metal frames, etc.) by connecting with testing machines, machine tools, or other processing equipment. This ensures that the workpiece remains stable during processing such as stretching, cutting, welding, and assembly, preventing displacement, slippage, or deformation, thereby guaranteeing processing accuracy and product quality.

[0003] Existing technologies for metal clamping carriers used in thin-walled shell processing still have certain drawbacks. When clamping thin-walled shells, traditional metal clamping carriers apply clamping force directly to the outer circle or end face of the thin-walled shell. Due to the small contact area and excessive pressure per unit area, the thin-walled shell is prone to local plastic deformation, resulting in clamping damage or deformation. Utility Model Content

[0004] The purpose of this utility model is to provide a metal clamping carrier for processing thin-walled shells that is resistant to deformation, in order to solve the problem mentioned in the background art that when traditional metal clamping carriers clamp thin-walled shells, the clamping force is directly applied to the outer circle or end face of the thin-walled shell. Due to the small contact area, the pressure per unit area is too large, which easily leads to plastic deformation in local areas of the thin-walled shell, resulting in clamping damage or deformation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant thin-walled shell metal clamping carrier, comprising a thin-walled shell clamping carrier, wherein a rotating opening and closing disc is provided on the surface of the thin-walled shell clamping carrier, the bottom surface of the rotating opening and closing disc is directly connected to a drive motor, the drive motor is located at the center of the bottom surface of the thin-walled shell clamping carrier, fixed supports are provided on both sides of the bottom surface of the thin-walled shell clamping carrier on the drive motor, a processing table is provided on the top of the rotating opening and closing disc, positioning slide rails are provided on the outer periphery of the processing table in four directions on the surface of the thin-walled shell clamping carrier, positioning sliders are provided on the positioning slide rails, a movable seat is provided above the positioning sliders, the movable seat is connected to a flexible clamp through a connecting rod, and a central positioning hole is provided at the center of the surface of the processing table.

[0006] In a further embodiment, the movable seat and the positioning slider are fixedly connected by a second fixing screw, and the cross-section of the positioning slider is designed as a concave structure.

[0007] In a further embodiment, one end of the connecting rod is fixedly connected to the movable seat by a first fixing screw, and the cross-section of the movable seat is set as a U-shaped structure.

[0008] In a further embodiment, the flexible clamp and the connecting rod are connected by an assembly block, and the assembly block and the connecting rod are fixedly connected by a third fixing screw.

[0009] In a further embodiment, the flexible clamp includes an elastic protrusion and a return spring. The inner end of the elastic protrusion is provided with a sealing plug, and the elastic protrusion is fixedly connected to the interior of the flexible clamp by the return spring. The bottom surface of the flexible clamp is provided with a sliding post, and the lower end of the sliding post passes through the sliding groove and slides into the angle limiting groove to slide and connect with the rotating opening and closing disc.

[0010] In a further embodiment, a fixing post is provided on the surface of the thin-walled shell clamping carrier at a position on the outer periphery of the rotating opening and closing disc and intersecting with the positioning slide rail. A fixing ear is provided on the outer periphery of the processing table at a position aligned with the fixing post, and the fixing ear and the fixing post are fixedly connected by hexagonal socket head cap screws.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The clamping action of the flexible chuck in this utility model is achieved by rotating the opening and closing disc to drive the sliding column, causing the flexible chuck to open and close. At the same time, it drives the moving seat to slide, changing the axial clamping to radial clamping and reducing radial deformation. This structure can disperse the clamping force of the flexible chuck, which can not only ensure the stability of the flexible chuck, but also prevent excessive clamping force. In addition, the inner end face of the flexible chuck is provided with multiple elastic protrusions. The elastic protrusions can be used to fix the thin-walled shell without damage, while dispersing the clamping force of the flexible chuck and preventing the thin-walled shell from being damaged or deformed during the clamping process.

Positioning sliders 4 are provided on the positioning slide rails 5. The table 6 is equipped with a movable seat 3, which is connected to the flexible chuck 2 via a connecting rod 16. A center positioning hole 14 is provided at the center of the surface of the processing table 6. The flexible chuck 2 is opened and closed by rotating the opening and closing disc 9. The movement of the rotating opening and closing disc 9 is controlled by the drive motor 11. The installation height of the thin-walled shell clamping carrier 1 is supported by the fixed bracket 12. The processing table 6 is used to place the thin-walled shell. The positioning slide rail 5 is used to position the sliding path of the positioning slider 4. The positioning slider 4 is used to install and fix the movable seat 3. The movable seat 3 is used to install the flexible chuck 2. The flexible chuck 2 is used to clamp and position the thin-walled shell.

[0024] The movable base 3 and the positioning slider 4 are fixedly connected by a second fixing screw 20, and the positioning slider 4 has a concave cross-section. The second fixing screw 20 is used to fix the movable base 3 and the positioning slider 4 together. One end of the connecting rod 16 is fixedly connected to the movable base 3 by a first fixing screw 19, and the movable base 3 has a U-shaped cross-section. The first fixing screw 19 is used to fix one end of the connecting rod 16 to the movable base 3 together. The flexible clamp 2 is connected to the connecting rod 16 by an assembly block 17, and the assembly block 17 is fixedly connected to the connecting rod 16 by a third fixing screw 24. The assembly block 17 is used to assemble and connect the flexible clamp 2 and the connecting rod 16 together.

[0025] The flexible chuck 2 includes an elastic protrusion 15 and a return spring 23. The inner end of the elastic protrusion 15 is provided with a sealing plug 22, and the elastic protrusion 15 is fixedly connected to the interior of the flexible chuck 2 by the return spring 23. The bottom surface of the flexible chuck 2 is provided with a sliding post 8, and the lower end of the sliding post 8 passes through the sliding groove 7 and slides into the angle limiting groove 21 to slide and connect with the rotating opening and closing plate 9.

Alternatively, the inner ring positioning mechanism can be installed in the center positioning hole 14 to position the inner ring of the thin-walled shell. The drive motor 11 converts electrical energy into mechanical energy to drive the rotating opening and closing plate 9 to rotate in the forward direction, so that the sliding column 8 moves along the path of the angle limiting groove 21, driving the flexible chuck 2 to perform a clamping action inward.

The elastic protrusion 15 increases the elasticity of the surface of the flexible chuck 2, dispersing the clamping force, thereby clamping and positioning the thin-walled shell.
