[0022] The utility model provides a honing fixture, such as Figure 1-3 As shown, it includes a honing seat 1, an upper positioning assembly and a lower positioning assembly. The honing seat 1 is provided with an upper positioning hole and a lower positioning hole. The axis of the upper positioning hole and the axis of the lower positioning hole are collinear. The upper positioning assembly is installed on the upper positioning hole, and the lower positioning assembly is installed on the lower positioning hole. The upper positioning assembly and the lower positioning assembly can be respectively inserted into the two ends of the center hole of the product 4 to clamp the product, so that the center line of the product 4 is collinear with the axis of the upper positioning hole, which can realize fast and accurate positioning of the clamping part, thereby meeting the coaxial requirements of the machine tool tool and the center hole of the product 4, suitable for positioning and clamping of large-scale products, and improves clamping efficiency; the existing clamping device generally clamps the two end faces of the product. Since the side walls of some products are thin, it is easy to affect the tolerance size of the center hole of the product during clamping. Therefore, the upper positioning assembly and the lower positioning assembly can be respectively inserted into the two ends of the center hole of the product to vertically press the product 4 up and down. When positioning and pressing the product 4, it will not cause adverse effects such as dimensional deformation to the porous product 4, and the size of the product 4 will not rebound after the clamping structure is loosened.

[0023] In the embodiment of the present invention, it is further preferred that the upper positioning assembly includes a clamping block 2 and a locking member. One end of the clamping block 2 can be inserted into the center hole of the product 4 through the upper positioning hole. The center line of the clamping block 2, the axis of the upper positioning hole, and the center line of the product 4 are collinear. The locking member is used to lock the clamping block and the honing seat. The locking member is a locking nut 3. The honing seat 1 is also provided with a locking hole. The locking hole is connected to the upper positioning hole, and the axis of the locking hole is perpendicular to the axis of the upper positioning hole. One end of the locking nut 3 passes through the locking hole and abuts against the clamping block 2. The clamping block 2 is inserted into the center hole of the product 4 to clamp the product 4. The clamping block 2 plays an auxiliary supporting role to prevent the upper end of the product 4 from swinging due to the cutting force of the tool when the tool rotates. The locking nut 3 locks the clamping block 2 to prevent the product 4 from moving up and down.

[0024] In an embodiment of the present invention, it is further preferred that the lower positioning assembly includes a machine positioning shaft 8 and a pad 5. One end of the machine positioning shaft 8 can be inserted through the lower positioning hole into the center hole of the product 4.
