[0019] See also Figure 1-3 The utility model provides an embodiment: an inner hole honing fastening device, including a base 1, a placement seat 2, a top cover 4 and a pressure cover 5. The base 1 is penetrated with a plurality of mounting holes, which can be installed and fixed with the honing machine by bolts. The top cover 4 is movably arranged above the base 1 through a first linear driving member 3. The first linear driving member 3 can be any one of an oil cylinder, an air cylinder, etc. The first linear driving member 3 is vertically fixed to the top of the base 1, and the output end is fixedly connected to the top cover 4. Through its extension and retraction, the top cover 4 is driven to move up and down, which is convenient for loading and unloading.

[0020] The placement seat 2 can be detachably mounted on the top of the base 1. Specifically, a positioning column 201 is fixed to the bottom end of the placement seat 2. A positioning through hole matching the positioning column 201 is penetrated through the center of the base 1. The positioning column 201 is a multi-prism structure, and in this embodiment it is a quadrangular prism structure. The positioning column 201 can be inserted into the positioning through hole to fix the placement seat 2 and the base 1 to avoid relative rotation.

[0021] The top of the placement seat 2 is provided with a placement groove that matches the workpiece 8 to be processed, and the middle of the positioning column 201 is penetrated by a through hole that is connected to the inside of the placement groove.

The second linear drive component 6 can be any one of an oil cylinder, an air cylinder, etc., and is horizontally installed on one side of the placement seat 2 through a mounting plate. A positioning hole 202 is provided on the side wall of the placement seat 2 to accommodate the output end of the second linear drive component 6 and extend to the inside. The output end of the second linear drive component 6 extends to the inside through the positioning hole 202, so that the workpiece 8 to be processed can be pressed against the inside of the placement seat 2 to avoid relative rotation between the workpiece 8 to be processed and the placement seat 2 when the outer surface of the workpiece 8 is cylindrical, thereby improving the stability of the workpiece 8 to be processed. In this embodiment, four positioning holes 202 are provided to facilitate the assembly of the placement seat 2. Furthermore, a top plate and a rubber pad can also be installed at the output end of the second linear drive component 6 to reduce wear.

[0023] A mounting hole matching the pressure cap 5 is provided at the center of the top cover 4. The pressure cap 5 can be detachably mounted inside the mounting hole of the top cover 4 to press the workpiece 8 downwards, and a through hole matching the inner hole to be processed of the workpiece 8 is provided at the center of the pressure cap 5. Specifically, the pressure cap 5 includes a cylinder 501 and a mounting portion 502 provided at the top edge of the cylinder 501. The mounting portion 502 is fixedly connected to the top cover 4 by bolts. Different pressure caps 5 can be replaced according to product needs. The cylinder 501 abuts against the edge of the workpiece 8 to be processed, and the workpiece 8 to be processed is pressed against the inside of the placement seat 2. The honing head of the honing machine can pass through the central through hole of the cylinder 501 to process the inner hole of the workpiece 8 to be processed.
