Description

Technical Field

[0001] This utility model relates to the field of automotive handle processing technology, and in particular to an automotive handle processing clamping device. Background Technology

[0002] Car door handles, often called door grabbers or door tactile handles, are primarily used for opening and closing car doors. They are typically designed with a horizontal pull-out mechanism, an ergonomic design that allows the driver to open the door with minimal effort and in the most comfortable posture.

[0003] A search revealed a patent (application number: 202020475702.6) disclosing a "clamping device for processing automotive handles." This device effectively fixes and supports the handle, and allows the operator to easily apply force to open the clamping device, thereby facilitating adjustment of the handle's position and improving work efficiency. However, this device has some problems during operation:

[0004] First, the device mainly relies on the front and rear clamps to hold the car handlebars close to each other. This clamping method has fewer support points and is not very stable. Furthermore, under the action of the spring, it is difficult to control the clamping force on the car handlebars. Excessive elasticity can easily damage the car handlebars, while insufficient elasticity can cause the car handlebars to fall off. Utility Model Content

A connecting frame is welded to the bottom outer wall of the clamp, and a column is welded to the bottom outer wall of the connecting frame. A worm gear is fixedly connected to the outer wall of the column, and a worm is engaged with the outer wall of the worm gear.

[0008] Preferably, the outer clamping plate includes symmetrically distributed side clamping blocks and an end clamping block disposed between the two side clamping blocks.

[0010] Preferably, the outer wall of the top of the base is welded with symmetrically distributed support frames, and the worm gear is rotatably connected to the inner walls of the two support frames.

[0011] Preferably, the top outer wall of the clamp has symmetrically distributed vertical grooves, and the outer clamping plate is slidably connected to the inner wall of the vertical grooves.

[0012] Preferably, the outer walls on both sides of the clamp are provided with transverse grooves, and the inner clamping plate is slidably connected to the inner wall of the transverse groove.

[0013] Preferably, the top outer wall of the clamp is provided with a car handle body, and both the outer clamp plate and the inner clamp plate are tightly attached to the outer wall of the car handle body.

[0014] Preferably, handrails are welded to both ends of the bottom outer wall of the clamp.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The car handle processing clamping device designed in this paper has two sets of outer clamping plates and inner clamping plates, which can clamp both the outer and inner walls of the car handle, increase the support points for the car handle, improve the positioning effect, and ensure the stability of the car handle during the processing.

The outer clamping plate 3 includes symmetrically distributed side clamping blocks 11 and an end clamping block 10 disposed between the two side clamping blocks 11.

[0027] In this embodiment, two sets of outer clamping plates 3 and inner clamping plates 5 are designed so that both the outer and inner walls of the car handle can be clamped, increasing the support points for the car handle, providing good positioning effect, and ensuring the stability of the car handle during the processing.

[0029] In this embodiment, with the cooperation of the lead screw 2 and the double-headed cylinder 4, the positions of the outer clamping plate 3 and the inner clamping plate 5 can be adjusted respectively. This not only makes it suitable for different sizes of car handlebars, but also controls the inner clamping plate 5 and the outer clamping plate 3 to fit against the inner and outer walls of the car handlebars. This allows for proper control of the clamping force of the car handlebars, preventing them from falling off or being damaged.

A worm gear 8 is fixedly connected to the outer wall of the column 7, and a worm 9 is engaged with the outer wall of the worm gear 8.

[0031] In this embodiment, under the transmission cooperation of worm 9 and worm wheel 8, rotating worm 9 can control worm wheel 8 to drive the car handle on fixture 1 to rotate, which makes it convenient to adjust the processing angle of car handle and has the feature of self-locking, reducing the difficulty for operators to process car handle.

[0032] Reference Figure 1 The bottom outer wall of the column 7 is fixedly connected to the chassis 14, and the outer wall of the chassis 14 is rotatably connected to the base 13.

[0033] Reference Figure 1 The base 13 has symmetrically distributed support frames 12 welded to the top outer wall, and the worm gear 9 is rotatably connected to the inner walls of the two support frames 12.

[0034] Reference Figure 2 and Figure 4 The top outer wall of the clamp 1 has symmetrically distributed vertical grooves 15, and the outer clamping plate 3 is slidably connected to the inner wall of the vertical grooves 15.

[0037] Reference Figure 3 Handrails 18 are welded to both ends of the bottom outer wall of fixture 1.

[0038] Working principle: First, the car handlebar is placed on the fixture 1. The double-headed cylinder 4 pushes the inner clamping plate 5 to fit against the inner wall of the car handlebar. Then, the outer clamping plate 3 is moved to fit against the outer wall of the car handlebar by rotating the lead screw 2, thus completing the positioning of the car handlebar on the fixture 1. During the processing, the worm gear 8 can be rotated by rotating the worm 9, which in turn drives the car handlebar on the fixture 1 to rotate, thereby adjusting the processing angle of the car handlebar.
