Detailed Description

The present invention will be further described with reference to the following examples, which should not be construed as limiting the invention.

In order to better understand the present invention, please refer to fig. 1 to 3, the driving plate inclined hole processing and fixing device includes a base, a fixing base plate 1 and a pressing plate 2, wherein the base is surrounded by a left side plate 3, a right side plate 3, a front support 4 and a rear wall plate 5 to form a rectangle for supporting the fixing base plate 1. The top surfaces of the left and right side plates 3 are inclined surfaces and are provided with semicircular grooves 6. The top surface of the front support 4 is provided with a height adjusting column, specifically, a washer 8 with a vertical threaded hole 7 is fixedly arranged on the top surface of the front support 4, a bolt 9 is screwed into the vertical threaded hole 7, the height of the bolt 9 is fixed through a locking nut 10 on the bolt 9, and the top end of the bolt 9 is fixedly connected with a cushion block 11. The top surface of the back wall plate 5 is fixed with a replacing block 12 through a transverse connecting screw, and the upper surface of the replacing block 12 is an inclined surface, and the inclined angle of the inclined surface is matched with the angle of an inclined hole 14 to be processed on a driving plate 13.

The fixed bottom plate 1 is a rectangular plate, cylindrical side shafts 15 are arranged on two sides of the rectangular plate, and the fixed bottom plate 1 is pivoted with the left side plate 3 and the right side plate 3 through the cylindrical side shafts 15 and the grooves 6. A first avoidance through hole 16 and a first fixing hole 17 are formed in the fixing bottom plate 1, and a connecting section at the bottom of the driving disc 13 extends into the first avoidance through hole 16 and is fixedly connected with the fixing bottom plate 1 through the first fixing hole 17 by a fixing bolt. The height of the front support 4 of the base is lower than the height of the rear wall panel 5. The front edge of the bottom of the fixed bottom plate 1 is processed into a chamfer angle which is supported by a cushion block 11 on the front support 4. The replacement block 12 on the rear wall panel 5 is supported on the bottom rear edge of the fixed base plate 1.
