Description

Technical Field

[0001] The present invention relates to the field of wire cutting processing, and particularly relates to a wire cutting group operation clamping device. Background Art

[0002] The existing clamping device for wire cutting of deep groove ball bearing groove R templates is as Figure 1 shown. The arrow direction is the wire cutting direction. Before processing, the operator first installs the pressing plate 1-4 on the end face of the bed body pad a1-1 by using the clamping bolt a1-3, places the upper part of the raw material a1-5 between the pressing plate 1-4 and the bed body pad a1-1, locks the raw material a1-5 on the bed body pad a1-1 by adjusting the clamping bolt a1-3, and then processes the deep groove ball R template 1-2 on the raw material a1-5 by wire cutting. Usually, the wire cutting for processing deep groove ball bearing groove R templates is to compile single-piece processing programs and process them one by one, which requires the operator to carefully control. Otherwise, the molybdenum wire will break, and even waste products will appear. While the processing efficiency is low, a large amount of raw materials will also be wasted. Moreover, the equipment cannot continue to work when there is no one to watch it at night.

[0003] In summary, the existing wire cutting operation clamping device has problems such as only being able to process single pieces during the wire cutting of deep groove ball bearing groove R templates, being prone to molybdenum wire breakage, resulting in a high scrap rate, low processing efficiency, and low automation level.

[0029] Working principle

[0030] Combined with Figures 2 to 4 To describe the working principle of a wire cutting group operation clamping device of the present invention:

[0031] First, the operator assembles the clamping device:

[0032] The upper groove R template 2-1 and the lower groove R template 2-2 are placed opposite to each other on the end faces of the two bed body pads b2-3. Multiple clamping members b2-6 are used to connect the upper groove R template 2-1 to one side of the bed body pad b2-3, and multiple clamping members b2-6 are used to connect the lower groove R template 2-2 to the other side of the bed body pad b2-3, so that a continuous sawtooth wave-shaped gap is formed between the sawtooth structures of the upper groove R template 2-1 and the lower groove R template 2-2.

[0033] Then, the operator clamps the raw material b2-7:

[0034] Both ends of the raw material b2-7 are respectively lapped on the end faces of the upper groove R template 2-1 and the lower groove R template 2-2. Multiple pressing members b2-4 are used to press one end of the raw material b2-7 against the upper groove R template 2-1, and multiple pressing members b2-4 are used to press the other end of the raw material b2-7 against the lower groove R template 2-2.

[0035] Finally, the operator performs wire cutting continuous group processing on the raw material b2-7:

[0036] The continuous sawtooth wave-shaped gap formed between the sawtooth structures of the upper groove R template 2-1 and the lower groove R template 2-2 is used as the wire walking path, and wire cutting processing operations are performed on the raw material b2-7 along the wire walking path by wire cutting.

[0037] By adopting the two-way cross idea, the stability of workpiece positioning is ensured, and the smoothness of the cutting line is ensured through two-way crossing. At the same time, after the workpiece is processed, it will not fall off, so there will be no wire clamping or wire breakage. At the same time, the edge of the previous workpiece after processing becomes the effective processing surface of the next product, and so on. Through program compilation, the group operation of products with different models and specifications is realized. After slow wire cutting and then fast wire cutting, the finished product processing can be completed.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
