Abstract
Description
Technical Field
[0001] The utility model relates to a tooling fixture, in particular to a fixture for processing ultra-thin fireproof washers. Background Art
[0002] Fireproof gaskets are often provided with concave-convex annular structures and are relatively thin. They can be produced by sheet stamping. However, when the diameter of the fireproof gasket is large and needs to be ultra-thin, sheet stamping cannot guarantee the processing accuracy of the size and is difficult to produce. If it is produced by machining, since there is no ideal special fixture at present, not only the processing steps are cumbersome, the production efficiency is low, and it is difficult to align the workpiece when repeatedly clamping the front and back sides, the processing error increases, and the yield rate is affected. Summary of the invention
[0003] In view of the deficiencies in the prior art, the utility model provides a special tooling fixture for ultra-thin fireproof washers which is convenient for efficient processing.
[0004] The utility model comprises a disc-shaped tooling body, on the front side of which an annular positioning protrusion is arranged, the outer diameter of the annular positioning protrusion corresponds to the inner diameter of a washer to be processed, a connecting hole is arranged at the center of the front side of the tooling body, and a front pressing plate used for pressing and fixing the washer to be processed can be connected to the connecting hole by bolts; an annular groove is arranged on the back side of the tooling body, the size of the annular groove corresponds to the size of the groove of the washer to be processed, and a pressure ring which is also used for pressing and fixing the washer to be processed is fixed by an edge pressing plate, and the edge pressing plate can be connected to the edge of the back side of the tooling body by bolts.
[0005] The utility model has a reasonable structure and is convenient for clamping. The front and back sides of the tooling body are respectively used for two-side processing of the workpiece. The positioning is accurate and the fixation is reliable. The processing steps are greatly saved, and the processing efficiency is greatly improved. In addition, it is easy to align when the front and back sides of the workpiece are repeatedly clamped, the processing accuracy is guaranteed, and the production quality is improved.
[0006] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] like Figures 1 to 3 As shown, an annular positioning protrusion 2 is provided on the front of the disc-shaped tool body 1, and the outer diameter of the annular positioning protrusion 2 corresponds to the inner diameter of the workpiece 8. A connecting hole 3 is provided at the center of the front of the tool body 1, and a front pressure plate 4 for clamping and fixing the workpiece 8 can be connected to the connecting hole 3 by bolts. An annular groove 5 is provided on the back of the tool body 1, and the size of the annular groove 5 corresponds to the size of the groove of the workpiece 8. A pressure ring 6 for clamping the workpiece 8 is fixed by an edge pressure plate 7, and the edge pressure plate 7 can be connected to the edge of the back of the tool body 1 by bolts.
[0013] When processing and using, the blank of the gasket to be processed, that is, the workpiece 8 is clamped on the front side of the tooling body 1, such as Figure 4 As shown, specifically, the inner diameter of the workpiece 8 is correspondingly sleeved on the annular positioning protrusion 2, and then the front pressure plate 4 can be connected to the connection hole 3 by bolts to press and fix the workpiece 8, and then the part of the workpiece 8 to be processed on this surface can be machined. After completion, the workpiece 8 is removed, and then the groove of the workpiece 8 is correspondingly placed in the annular groove 5 on the back side of the tooling body 1, and the pressure ring 6 presses the outer ring of the workpiece 8. The edge pressure plate 7 connected to the back side edge of the tooling body 1 by bolts can fix the pressure ring 6, as shown in FIG. Figure 5 As shown, the part to be processed of the workpiece 8 on this surface can then be machined.
[0014] In this embodiment, a redundant annular groove 9 is further provided on the reverse side of the tool body 1 adjacent to the inner diameter of the annular groove 5, and the redundant annular groove 9 is connected to the annular groove 5 and has a recessed depth smaller than the annular groove 5. This not only facilitates the placement and removal of the workpiece 8, but also provides a larger tool operating space during machining, making machining more convenient and accurate.
