Description

Technical Field

[0001] This invention belongs to the field of precision machining and relates to a clamping and positioning device for a moving mechanism and an auxiliary machining device. Background Technology

[0002] With the continuous improvement of product precision requirements and production efficiency, the existing processing methods mostly adopt the method of first processing a rough datum and then using the rough datum for processing. If the precision of the part is too high, it is necessary to add a fine machining datum and a fine machining process. This process requires multiple clamping, which makes it difficult to guarantee the precision of the part, greatly increases the part processing time, and requires higher technical skills from the processing personnel. Summary of the Invention

[0003] To address the aforementioned technical problems in the prior art, this invention proposes a clamping, positioning, and auxiliary processing device for a movable mechanism, the specific technical solution of which is as follows: A clamping, positioning, and auxiliary processing device for a movable mechanism includes a square box, a positioning module, and a fixing module. The positioning module is fixedly mounted on the square box by bolts, and the fixing module is located on the opposite side of the positioning module, with the distance between the two being adjustable. The positioning module is provided with several pads for supporting the workpiece.

[0004] Furthermore, the positioning module also includes a substrate, and the pads include a first pad, a second pad, and a third pad. The first pad and the third pad are arranged on both sides of the substrate surface, and the second pad is located in the middle area of ​​the substrate surface.

[0005] Furthermore, the first and third pads adopt a concave structure.

[0006] Furthermore, the fixing module includes a pressure plate and a clamping assembly, wherein the pressure plate is fixed to the end of the clamping assembly.

[0007] Furthermore, the clamping assembly includes a bolt and nut structure and a connecting rod, which is fixedly connected to the nut and moves axially along the bolt as the nut rotates.

[0008] Furthermore, the pressure plate is fixed to the end of the connecting rod and is disposed corresponding to the surface of the substrate.

[0009] The beneficial effects of this invention include: 1. By using a single clamping method, the machining accuracy of both ends of the part can be guaranteed to meet the design requirements when the part is too long, and as many faces as possible can be machined, reducing the time spent on multiple clamping operations and thus reducing the machining time.

[0010] 2. The positioning module is used to position the workpiece, and the fixing module is used to fix the workpiece. When machining the workpiece, you only need to calibrate the workpiece and process it according to the predetermined program after tool setting. The accuracy of the workpiece is guaranteed by the machine tool and the quality of the blank, which reduces the technical dependence on the operator. Even if the operator is not familiar with the workpiece, the machining accuracy can be guaranteed.

[0011] 3. It has a simple structure and high reliability. Compared with traditional clamping methods, it has high processing efficiency and can achieve a unified positioning datum for all machined surfaces of the part. Attached Figure Description

Detailed Implementation

[0013] To make the objectives, technical solutions, and technical effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figures 1 to 3 As shown, this embodiment of a clamping, positioning, and auxiliary processing device for a movable mechanism includes a square box 1, a positioning module 2, and a fixing module 3. The square box 1 and the positioning module 2 are connected by bolts. Before processing, the square box 1 is fixed on the worktable of a horizontal machining center, and then the positioning module 2 is connected to the square box 1.

[0015] like Figures 4 to 6 As shown, the positioning module 2 includes a base plate 4, a first pad 5, a second pad 6, and a third pad 7. Each pad is arranged on the base plate 4 according to the shape of the workpiece and processing requirements, and is used for positioning and correction of the workpiece to ensure processing accuracy. In one embodiment, the first pad 5 and the third pad 7 may adopt a concave structure to prevent the workpiece placed therein from shifting out from both sides.

[0016] like Figure 7As shown, the fixing module 3 includes a pressure plate 8 and a clamping assembly 9. The clamping assembly 9 includes a bolt and nut structure and a connecting rod that moves with it. The connecting rod is fixed to the nut, and the pressure plate 8 is fixed to the end of the connecting rod. By pre-tightening or loosening the nut, the workpiece can be quickly clamped or released through the pressure plate 8.

[0017] During processing, the workpiece is placed on the positioning module 2, and after calibration, it is clamped by the fixing module 3, and then tool setting and processing can be performed.
