Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a precision tooling for a cavity box product. Background Art

[0002] During the mechanical processing, it is often necessary to process box-type products containing cavities. Because the middle part of the box contains a cavity, the side walls of the cavity box-type products are easily deformed during the processing, which leads to large dimensional deviations of the finished products. In addition, the appearance requirements of cavity box-type products are high. If a clamp is used during the processing, it is easy to clamp the surface of the product. Therefore, the industry usually uses direct mold opening to process cavity box-type products. However, the mold opening method has low processing accuracy and is not suitable for high-precision product requirements. Utility Model Content

The machine program controls the vacuum suction mechanism to suck the cover plate tightly, and controls the elastic side push mechanism to automatically press the product. The product's outer shape surface is used as the fine positioning, and the molding cavity is used as the rough positioning and clamping to ensure high-precision dimensions without clamping the product.

[0018] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively with reference to the relevant drawings. Several embodiments of the utility model are given in the drawings. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] See also Figures 1 to 3 The embodiment of the utility model provides a cavity box product precision tooling, including a base 10, a plurality of elastic side-thrusting mechanisms 20 arranged at the upper end of the base 10, a positioning plate 30 arranged at the pushing side of the elastic side-thrusting mechanism 20, and a cover plate 40 arranged at the upper end of the positioning plate 30, and side-thrusting holes 31 are provided at the positions corresponding to the positioning plate 30 and each of the elastic side-thrusting mechanisms 20, and a plurality of molding cavities 32 are spaced apart in the middle of the positioning plate 30, and each of the side-thrusting holes 31 is connected to one of the molding cavities 32.

[0022] The above-mentioned cavity box product is precisely tooled, and the cover plate 40 is loaded with the product into the molding cavity 32 of the positioning plate 30 on the base 10. The machine program controls the vacuum suction mechanism to suck the cover plate 40 tightly, and controls the elastic side push mechanism 20 to automatically press the product. At this time, the product's outer shape surface is used as the fine positioning, and the cavity surface of the molding cavity 32 is used as the rough positioning and clamping, which can ensure high-precision dimensions and will not clamp the product.

[0023] In one embodiment of the utility model, a plurality of positioning posts 50 are provided on the edge of the upper end of the positioning plate 30 , and a first positioning hole 41 is provided at a position corresponding to each positioning post 50 on the cover plate 40 to facilitate installation and positioning of the cover plate 40 and the positioning plate 30 .
