Embodiment 1

[0027] In the present invention, the number of the edge support positioning device and the universal support, as well as the number of the base frame and the splicing blocks of the bracket are changed according to the size of the parts. The flexible clamp in this embodiment, such as figure 1 Shown is a flexible fixture that contains six edge support positioning devices and eight universal supports to illustrate the technical solution of the present invention.

[0028] The specific implementation process is as follows:

[0029] combine figure 2 , the base frame 1 adopts a splicing structure, and the length and width dimensions can be adjusted by increasing or decreasing the number of length blocks 1-3 and width blocks 1-4. According to the size of the parts, determine the number of length blocks 1-3 and width blocks 1-4 of the base frame 1 to complete the splicing of the base frame.

[0030] Edge support device 2 such as image 3 As shown, it includes a slider 2-1, a horiz...

Abstract

The invention discloses a flexible clamp suitable for positioning and clamping complex curved surfaces of parts. The flexible clamp comprises a base frame, edge positioning and supporting devices, universal supports, support brackets and supporting parts in various types, wherein the edge positioning and supporting devices are arranged on base frame guide rails and have the actions of positioning and supporting the edges of the parts; the support brackets are arranged in the base frame and used for mounting the universal supports and adjusting the positions of the universal supports; the universal supports are adjustable in angle and height and can be adapted to supporting the complex curved surfaces of the parts; and the supporting parts are in various types, are arranged on the corresponding universal supports, are in contact with the curved surfaces of the parts and have the actions of positioning and supporting the parts. The flexible clamp is suitable for positioning and clamping the complex curved surfaces of the parts, can replace a special clamp and a special tool, has good adaptation to the parts with the complex curved surfaces and poor rigidity, and thus the special clamp is prevented from being designed and manufactured in the production process. The flexible clamp is higher in flexibility and operability, has a simple structure and is low in cost.

Description

technical field [0001] The invention relates to the field of processing automotive interior parts, in particular to a flexible clamp suitable for positioning and clamping complex curved surfaces of parts. Background technique [0002] Automotive interior parts are an important part of the car, and the interior parts of different models often have great differences in shape and structure. With the introduction of new models and the continuous acceleration of replacement, the production of automotive interior parts is developing in the direction of multiple varieties and small batches. [0003] Due to the thin wall thickness, complex curved surface, large structural size, and poor rigidity of automotive instrument panels and other interior parts, they are easily deformed during machining, so it is necessary to make corresponding fixtures. However, in the case of multi-variety and small-batch production, the cost of fixtures is relatively high. Realizing the flexible clamping...
