Problems solved by technology

[0003] It can be seen from the above that the traditional rotary table drilling method mainly has the following problems: 1. Every workpiece needs to manually draw a line to find the center of the circle. Obviously, the efficiency of manually drawing a line to find the center of the circle will be very low. The product scrap rate is also high; 2. In order to make the drill bit to process the equal-round through hole C, the turntable to be drilled must be raised. The traditional spacer can play a role in raising the height, but the position of the spacer needs to be constantly changed according to the position of the drilled hole , Lock the pressure plate-loosen the pressure plate-adjust the cushion block-relock the pressure plate again, such an operation step needs to be operated many times for a product, which is a waste of time, the production efficiency is very low, and the labor intensity of the staff is also very high; 3. Drilling machine The drill bit is aligned with the center of the circle with the naked eye, and there will be errors to some extent. There is no self-correction function in the processing process, and the precision of the processed product is relatively poor. If the error is large, the product will be scrapped directly; 4. A drilling machine cannot independently complete the turntable. For processing, the diameter of the drill bit is a fixed value. The drill bit of the traditional drilling machine cannot pass through the equal-circle through hole A to expand the equal-circle through-hole B. To expand the hole, the boring tool of the boring machine is required. The boring tool has a telescopic function and can pass through the equal-circle through-hole A for processing. Equal round through hole B, but frequent tool setting is required in this process; generally there are nine equal round through holes A on the turntable, that is to say, nine times of tool setting are required to process one turntable, which is labor-intensive and time-consuming, which is greatly reduced again. Product production efficiency; in addition, the enterprise needs to purchase two sets of equipment, and the processing cost is high; 5. The product needs to be transported from the drilling machine to the boring machine, and the minimum size of the turntable of the tablet press is 40 kg. The manpower, material resources, and The time and cost will reduce the production efficiency of the enterprise again; 6. The tool setting of the boring machine is a technical work, and there is a high requirement for the experience of the master

Embodiment 1

[0072] A method for drilling a turntable of a tablet press, wherein the isocircular through holes on the turntable 1 of the tablet press include the following processing steps:

[0073] a. The lower hole reference plate 23 is prepared in advance, and the middle position of the lower hole reference plate 23 is fixed with a connecting rod 22; the lower hole reference plate 23 is pre-opened with a lower substrate through hole 231 corresponding to the equal circular through hole C131;

[0074] b. Set the turntable to be drilled on the connecting rod 22, and the turntable to be drilled after being inserted has no degree of freedom in the horizontal direction;

[0075] c. Cover the upper hole reference plate, and the upper base plate through-hole corresponding to the isocircular through hole A is pre-opened on the upper hole reference plate. When placing the upper hole reference plate, it is necessary to align the upper base plate through hole The through holes of the lower substrat...

Embodiment 2

[0085] This embodiment is based on embodiment 1. The assembly in step e of embodiment 1 is fixed on the workbench 33 of the drilling machine 3 through the index plate 5 with the claw 51, and the claw 51 on the index plate 5 is locked. The lower hole reference plate 23 is tightened, and the chassis 52 of the index plate 5 is fixed on the workbench 33 of the drilling machine 3 by bolts. The assembly is placed on the claws, the claw screw is adjusted to lock the assembly, and the crank handle of the indexing plate is turned to adjust the rotation angle of the assembly. The indexing plate with claws is the prior art. The claws are used to fix the assembly on the workbench, and the indexing plate is used to adjust the rotation angle of the assembly. The operation is simple and convenient, and the time for the drill bit to align with the center of the circle can be shortened ,Shorten the production cycle.
