Embodiment 1

[0045] see figure 1 and figure 2 , a processing jig 200 of this embodiment can be applied to the processing of the guide arm 100. Through one-time clamping and positioning, the processing of both sides of the guide arm 100 can be realized, which reduces processing errors, reduces labor intensity, and improves production efficiency.

[0046] In this embodiment, a guide arm 100 to be processed is also provided. The guide arm 100 is applied to the installation suspension of automobiles. The guide arm 100 is a long square shape. After bending, the guide arm 100 is Z-shaped, and the center line of symmetry of the guide arm 100 is located in the length direction of the guide arm 100 .

[0047] The guide arm 100 includes three sections connected in sequence along the length direction. The three sections are the short cross arm 110, the vertical arm 120 and the long cross arm 130. The long cross arm 130 is set at the end far away from the short cross arm 110. There are 140 roll ea...

Embodiment 2

[0057] see Figure 1 to Figure 5 , a processing jig 200 of this embodiment can be applied to the processing of the guide arm 100. Through one-time clamping and positioning, the processing of both sides of the guide arm 100 can be realized, which reduces processing errors, reduces labor intensity, and improves production efficiency. This embodiment is an improvement made on the technical basis of the above-mentioned embodiment 1. Compared with the above-mentioned embodiment 1, the difference lies in:

[0058] Please refer to Figure 5 and Figure 6 , in this embodiment, for the convenience of description, one of the two positioning mechanisms 221 is described. The driving assembly 2210 in the positioning mechanism 221 includes a transmission shaft 2210b, a driving seat 2210d and a first driving member 2210a.

[0059] Wherein, the transmission shaft 2210b is rotatably installed on the driving seat 2210d, and the two ends of the transmission shaft 2210b respectively extend to ...

Embodiment 3

[0068] see Figure 1 to Figure 5 , a processing jig 200 of this embodiment can be applied to the processing of the guide arm 100 . This embodiment is an improvement made on the technical basis of the above-mentioned embodiment 2. Compared with the above-mentioned embodiment 2, the difference lies in:

[0069] Please refer to Figure 5 and Figure 7 In this embodiment, the driving assembly 2210 includes two transmission shafts 2210b, a driving seat 2210d and a first driving member 2210a, the two transmission shafts 2210b are slidably disposed on the driving seat 2210d, and the two transmission shafts 2210b are mirror images of each other. Wherein, the ends of the two transmission shafts 2210b that are close to each other are provided with external threads with opposite rotation directions, and the ends of the two transmission shafts 2210b that are far away from each other are respectively provided with clamping blocks 2211 .

[0070] In order to prevent the transmission shaf...

Abstract

The invention provides a machining clamp and machining equipment, and relates to the technical field of machining. The machining clamp comprises a base, a clamping structure and a grip structure. The clamping structure comprises two positioning mechanisms, the two positioning mechanisms are distributed along the symmetric center line of the base in the length direction, and the two positioning mechanisms are used for positioning a guide arm, so that the symmetric center line of the guide arm coincides with the symmetric center line of the base in the length direction; each of the two positioning mechanisms comprises a driving assembly and two clamping blocks, the two clamping blocks are arranged on the driving assembly, the two clamping blocks are symmetrically arranged about the symmetrical center line of the base in the length direction, and a first driving part drives the two clamping blocks to be close to or away from each other; and the grip structure is arranged on the base and used for clamping the positioned guide arm. According to the machining clamp, the two side faces of the guide arm can be machined at the same time through one-time clamping and positioning, the machining error is few, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing fixture and processing equipment. Background technique [0002] The guide arm is generally used in the installation suspension of automobiles. It is Z-shaped in structure. One end of the guide arm is provided with a roll ear, and the section connected to the roll ear is a cross arm section. The opposite sides of the cross arm section need to be processed flat. face for easy assembly. [0003] In the prior art, the guide arm is bent into a Z-shape by a steel bar, and the two sides of the cross-arm section are reserved for machining. When processing, one of the sides of the cross-arm section needs to be Machining is performed, and then the other side is machined using this side as the datum plane. Therefore, the guide arm needs to be processed twice, and then multiple times of clamping and positioning are required, resulting in large processing errors, ...
