Description

Technical Field

[0001] The invention relates to a tooling die for processing annular reinforcing ribs, in particular to a universal die for processing radial threaded holes and water flow grooves on annular reinforcing ribs. Background Art

[0002] Many rotary metal shell products are equipped with metal annular ribs. In order to facilitate the assembly of the annular ribs and the products, some parts must be pre-processed on the annular ribs, such as cross-line marking, radial threaded holes, and water flow channels. When there are many ribs and the batch is large, if the traditional work steps are used and completed separately, it will take a lot of time and manpower, and the size of the holes or water flow channels processed on the ribs will be out of tolerance, making it difficult to ensure the processing quality of the ribs, resulting in a large number of ribs being scrapped. The traditional working steps are as follows: the first step is for the fitter to place the annular reinforcement blank on the work platform, align the workpiece, and use a steel ruler, a square ruler, and a stylus to draw cross lines and hole position lines on the end face of the workpiece, which serve as a reference for the subsequent processing of threaded holes, water troughs, and arc-shaped notches; the second step is to use a vise to fix the reinforcement, place the sample tooling for making water troughs at the actual position of the reinforcement trough, clamp and fix it, and make the water trough according to the holes on the tooling; the third step is to fix the reinforcement on the magnetic drill work platform, and make the threaded bottom hole according to the hole position line. This processing method has many steps, cumbersome operations, and low processing efficiency, and is particularly unsuitable for mass production of reinforcements. Summary of the invention

[0003] The invention provides a universal die for machining radial threaded holes and water flow channels with stepped annular reinforcement ribs, which solves the technical problems of numerous machining steps, poor machining consistency and low machining efficiency in the existing step-by-step machining of parts on annular ribs.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A universal mold for processing radial threaded holes and water flow grooves with stepped annular reinforcement ribs comprises a circular mold base and a zigzag plug plate frame, an inner annular boss is arranged on the circular mold base, and line sample columns are arranged at intervals of 90 degrees on the top surface of the inner annular boss, an annular clamping groove is arranged on the top surface of the circular mold base outside the inner annular boss, an annular stepped reinforcement rib is clamped in the annular clamping groove, the annular inner raised step of the annular stepped reinforcement rib is abutted against the inner annular boss arranged on the circular mold base, a radial threaded hole drilled through hole is arranged on the side wall of the inner annular boss, an arc groove is arranged on the lower step of the zigzag plug plate frame, the circular mold base is clamped in the arc groove, an plug plate through hole is arranged on the upper step of the zigzag plug plate frame, a plug plate is movably plugged in the plug plate through hole, a water flow groove drilled through hole is arranged on the inner side end of the plug plate, and a top screw is arranged between the plug plate and the zigzag plug plate frame.

[0006] A workpiece pressing plate is arranged on the top surface of the outer ring of the annular mold base.

[0007] The universal mold of the present invention completes three working steps of marking the cross positioning line, processing the radial threaded holes on the inner wall of the annular rib and processing the axial water flow groove on the tooling at one time. Compared with the traditional process, the processing qualification rate is significantly improved, the cost is greatly reduced, the processing efficiency is significantly improved, and it is particularly suitable for mass production.

[0015] The present invention is described in detail below in conjunction with the accompanying drawings:

[0016] A universal mold for processing radial threaded holes and water flow grooves with stepped annular reinforcement ribs, comprising a circular mold base 1 and a zigzag plug-in plate frame 8, an inner annular boss 2 is arranged on the circular mold base 1, and marking sample columns 6 are arranged at intervals of 90 degrees on the top surface of the inner annular boss 2. When the annular stepped reinforcement rib 4 is placed on the mold, the marking of the cross positioning line can be completed accurately and quickly through these four marking sample columns 6; an annular clamping groove 3 is arranged on the top surface of the circular mold base 1 outside the inner annular boss 2, and an annular stepped reinforcement rib 4 is clamped in the annular clamping groove 3. As long as the annular stepped reinforcement rib 4 is placed in the annular clamping groove 3, the marking task can be quickly completed, and the annular inner convex step 5 of the annular stepped reinforcement rib 4 is abutted against the inner annular boss 2 arranged on the circular mold base 1, and a radial threaded hole drilled through hole 7 is arranged on the side wall of the inner annular boss 2, and a radial threaded hole drilled through hole 7 is drilled on the inner side surface of the inner annular boss 2 pre-arranged on the circular mold base 1. By setting the drilling position of the radial threaded hole to be punched on the workpiece product, the radial threaded hole on the inner wall of the workpiece can be accurately and quickly processed. The drill bit of the electric drill drills the radial threaded hole 7 to drill the radial threaded hole 16 on the inner wall of the annular stepped reinforcing rib 4; an arc groove 9 is provided on the lower step of the zigzag plug-in plate rack 8, and the annular mold base 1 is clamped in the arc groove 9, and a plug-in plate through hole 10 is provided on the upper step of the zigzag plug-in plate rack 8. 0 is movably connected with a plug plate 11, and a water flow groove drill hole 12 is set on the inner side end of the plug plate 11, and a top screw 13 is set between the plug plate 11 and the zigzag plug plate frame 8; after the top screw 13 is loosened, the position between the zigzag plug plate frame 8 and the circular mold base 1 can be easily adjusted, and the drilling position of the axial water flow groove 15 on the annular stepped reinforcement rib 4 can be conveniently positioned. The drill bit of the electric drill drills the axial water flow groove 15 on the annular stepped reinforcement rib 4 through the water flow groove drill hole 12.
