The fixture has the advantages of reasonable structure, convenient clamping, accurate positioning, reliable fixation, great saving of processing steps, great improvement of processing efficiency, easy alignment when the front and the back of the workpiece are clamped repeatedly, guaranteed processing precision and improved production quality, and the front and the back of the fixture body are respectively used for processing the two faces of the workpiece.
Description
Technical Field
The utility model relates to a fixture, in particular to a fixture for processing an ultrathin fireproof gasket.
Background
Fireproof gaskets are often provided with concave-convex annular structures and are thinner, and can be produced in a sheet stamping mode, but when the caliber of the fireproof gasket is larger and ultrathin is needed, the sheet stamping mode cannot ensure the machining precision of the size, and the fireproof gasket is difficult to produce. If the machining mode is adopted for production, because no ideal special fixture exists at present, the machining steps are complicated, the production efficiency is low, alignment is not easy to occur when the front and the back of the workpiece are clamped repeatedly, the machining error is increased, and the yield is affected.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides the special fixture for the ultrathin fireproof gasket, which is convenient to process efficiently.
The novel tool comprises a disc-shaped tool main body, wherein an annular positioning bulge is arranged on the front surface of the tool main body, the outer diameter of the annular positioning bulge is correspondingly matched with the inner diameter of a washer to be processed, a connecting hole is formed in the center of the front surface of the tool main body, a front pressing plate for pressing and fixing the washer to be processed can be connected to the connecting hole through a bolt, an annular groove is formed in the back surface of the tool main body, the size specification of the annular groove is correspondingly matched with the size of the groove of the washer to be processed, a pressing ring for pressing 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 surface of the tool main body through a bolt.
The fixture has the advantages of reasonable structure, convenient clamping, accurate positioning, reliable fixation, great saving of processing steps, great improvement of processing efficiency, easy alignment when the front and the back of the workpiece are clamped repeatedly, guaranteed processing precision and improved production quality, and the front and the back of the fixture body are respectively used for processing the two faces of the workpiece.
The utility model is further described below with reference to the drawings and the detailed description.

Detailed Description
As shown in fig. 1 to 3, an annular positioning protrusion 2 is arranged on the front surface of a disc-shaped tool main body 1, the outer diameter of the annular positioning protrusion 2 is correspondingly matched with the inner diameter of a workpiece 8, a connecting hole 3 is arranged in the center of the front surface of the tool main body 1, and a front pressure plate 4 for pressing and fixing the workpiece 8 can be connected to the connecting hole 3 through bolts. The back surface of the tool main body 1 is provided with an annular groove 5, the size specification of the annular groove 5 is correspondingly matched with the groove size of the workpiece 8, the pressing ring 6 for pressing the workpiece 8 is fixed by an edge pressing plate 7, and the edge pressing plate 7 can be connected with the edge of the back surface of the tool main body 1 through bolts.
When in processing and use, a blank of a gasket to be processed, namely a workpiece 8 is clamped on the front side of the tool main body 1, as shown in fig. 4, specifically, the inner diameter of the workpiece 8 is correspondingly sleeved on the annular positioning bulge 2, then the front side pressing plate 4 can be connected to the connecting hole 3 through bolts, the workpiece 8 is pressed and fixed, and the part of the workpiece 8 to be processed on the surface can be machined. After the completion, take down work piece 8, place work piece 8's recess correspondence in frock main part 1 reverse side's annular groove 5 again, clamping ring 6 pushes down work piece 8's outer lane, can fix clamping ring 6 through bolted connection at frock main part 1 reverse side edge's edge clamp plate 7, as shown in fig. 5, then can carry out the machining to the work piece 8 of this face and wait to process the position.
In the embodiment, a redundant ring groove 9 is further arranged on the back surface of the tool main body 1 adjacent to the inner diameter of the annular groove 5, the redundant ring groove 9 is communicated with the annular groove 5, and the concave depth is smaller than that of the annular groove 5. Therefore, the tool 8 is convenient to take and place, the tool operation space is larger during machining, and machining is more convenient and accurate.
