Work clamp matched with universal miller and used for milling seam faces of glass molds

Abstract

The invention discloses a work clamp matched with a universal miller and used for milling seam faces of glass molds. The universal miller comprises a miller main shaft and a miller working platform. The work clamp comprises a baseboard, a first adjustment support, a second adjustment support, a guide rail seat, a fixed mold clamping seat, a movable mold clamping seat and a screw, wherein the baseboard is arranged on the miller working platform, the first adjustment support and the second adjustment support are arranged at the two ends of the baseboard, at least one first adjustment pressing plate and one second adjustment pressing plate are arranged on the top portion of the first adjustment support and on the top of the second adjustment support, the guide rail seat is fixedly arranged on the middle portion of the baseboard, a pair of guide rails are formed on the guide rail seat, the fixed mold clamping seat corresponds to the movable mold clamping seat, a screw sliding sleeve is configured on the movable mold clamping seat, one end of the screw is connected with the fixed mold clamping seat, the other end of the screw is matched with the screw sliding sleeve, and a screw manipulation handle is fixedly arranged on the end portion, extending out of the screw sliding sleeve, of the screw. The work clamp matched with the universal miller and used for milling the seam faces of the glass molds is convenient to manufacture, to use and to maintain, cheap, capable of meeting the requirement of machining concave arc surfaces on the seam faces of the glass molds, high in machining efficiency, not heavy in working strength, and is suitable for molds of different standards. Further, by means of the work clamp, the glass molds do not loose when the glass molds are milled with milling cutters.

Description

technical field [0001] The invention belongs to the technical field of tooling fixtures, and in particular relates to a tooling fixture for joint face milling of glass molds matched with a universal milling machine. Background technique [0002] Fixtures play a very important role in the production of industrial products, and the processing of glass molds is no exception. The so-called tooling fixture refers to special equipment or tools used to clamp or position workpieces in machining to meet certain process requirements. Fixtures usually need to meet the requirements of no interference during product production, accurate and reliable positioning, and convenient operation. Since the tooling fixture has the exclusive characteristics of manufacturing a certain product, the degree of generalization is low, and it is often made by the manufacturer of the product. Glass mold manufacturers are also mostly equipped with various tooling fixtures in a self-made way. Because glas...

Problems solved by technology

[0003] In the existing technology, there are mainly two processing methods for processing concave arc surfaces on the joint surface of glass molds; one is to file them out with a file by experienced workers (fitters), but this manual method has the disadvantages of high labor intensity and The lack of low efficiency and difficult to guarantee quality; the second is to use CNC machining center milling, although this method can make up for the lack of manual file processing of the former to a certain extent, but due to the need to start from the programming theory, an arc or called The arc segment is converted into several straight segments, so the finish of the milled surface is poor and the milling efficiency is still low

In addition, due to the large investment of CNC machining centers, if an expensive machining center is purchased only for milling the concave arc surface of the joint surface of the glass mold, it will undoubtedly cause a waste of equipment resources, and as an ordinary glass manufacturer, the expensive CNC Machining centers are often prohibitive (due to large investment in preparation)

[0004] Undoubtedly, the use of ordinary universal milling machine to mill the joint surface of glass mold can effectively make up for the lack of the above two processing methods. However, due to the lack of tooling fixtures for reliable clamping of glass molds that are matched with universal milling machines, Therefore, the industry still has no choice but to rely on manual processing, that is, the workers use files to file the joint surface.
