Description

Technical Field

[0001] This application belongs to the field of workpiece grinding technology, specifically a grinding fixture and grinding machine that work together with a grinding machine. Background Technology

[0002] When grinding the circumferential surface of a cylindrical workpiece, a typical grinding machine uses two opposing positioning axes to coaxially support the center of both ends of the workpiece. The two positioning axes are then driven to rotate, causing the workpiece to rotate as well. During this rotation, the grinding head contacts the circumferential surface of the workpiece to achieve grinding. However, in this method, the positioning axes can only make near-point contact with the ends of the workpiece during rotation, meaning the contact area is too small. Therefore, it is very easy for the positioning axes to slip during the process of driving the workpiece. Thus, it is necessary to explore another grinding fixture. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by setting slots on the fixture body to achieve the clamping function, and by setting a chuck on the fixture body to cooperate with the grinding machine drive, thereby solving the problem of how to prevent slippage during the process of driving the workpiece by the positioning axis.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A grinding fixture for use with a grinding machine includes a fixture body with a through hole in the center and a slot on the fixture body. One end of the slot extends into the through hole, and the other end extends out of the fixture body. A locking pin is provided on the fixture body, perpendicular to the axis of the through hole. A screw hole is provided on the fixture body, with its axis parallel to the locking pin. The slot extends through both ends of the screw hole, and at least one end of the screw hole is located outside the fixture body. A screw is screwed into the screw hole from outside the fixture body.

[0006] Preferably, the clamp body is cylindrical, the through hole is coaxial with the clamp body, and the slot penetrates the upper and lower end faces of the clamp body.

[0007] Preferably, the clamp body has a first notch on one side of the slot, and one end of the screw hole extends from the first notch to the outside of the clamp body.

[0008] Preferably, the inner wall of the through hole is provided with a protrusion, which is parallel to the axis of the through hole.

[0009] Preferably, a through hole is provided radially between the two ends of the locking pin.

[0010] Preferably, a second notch is provided between the two ends of the locking pin, and the inner surface of the second notch has a smooth structure.

[0011] Preferably, the clamp body is made of stainless steel.

[0012] A grinding machine using the above-mentioned grinding fixture includes a grinding machine body. A fixed seat and a sliding seat are respectively provided at opposite ends of the upper surface of the grinding machine body. The sliding direction of the sliding seat faces the fixed seat. A first conical column is rotatably provided on the fixed seat, and a second conical column is provided on the sliding seat. The first and second conical columns face each other and are coaxial. A rotating ring coaxial with the first conical column is rotatably provided on the fixed seat. A shift pin is fixedly provided on the rotating ring facing the sliding seat. The shift pin is parallel to the first conical column, and the distance from the shift pin to the axis of the first conical column is less than the distance between the chuck pin and the center of the through hole.

Detailed Implementation

[0021] like Figure 1-5As shown, a grinding fixture for use with a grinding machine includes a fixture body 1, a through hole 2 in the center of the fixture body 1, a slot 3 on the fixture body 1, one end of the slot 3 extending into the through hole 2 and the other end extending out of the fixture body 1, a locking pin 4 on the fixture body 1, the locking pin 4 being perpendicular to the axis of the through hole 2, a screw hole 5 on the fixture body 1, the axis of the screw hole 5 being parallel to the locking pin 4, the slot 3 passing through both ends of the screw hole 5, at least one end of the screw hole 5 being located outside the fixture body 1, and a screw 10 being screwed into the screw hole 5 from outside the fixture body 1.

[0022] In this embodiment, when in use, the two ends of the workpiece 20 are first passed through the through holes 2. Then, screws 10 are screwed into the screw holes 5 so that the fixture body 1 clamps the circumferential surface of the workpiece 20. Then, the fixture body 1 and the workpiece 20 are placed coaxially between the first tapered column 14 and the second tapered column 15 on the grinding machine body 11. Then, the grinding machine body 11 pushes the sliding seat 13 toward the fixed seat 12 and fixes the sliding seat 13 to the grinding machine body 11. At this time, the first tapered column 14 and the second tapered column 15 clamp the two ends of the workpiece 20. Then, the rotating ring 16 is rotated. The push pin 17 on the rotating ring 16 pushes the column 4 as the rotating ring 16 rotates, so that the workpiece 20 rotates around the axis of the first tapered column 14 of the grinding machine body 11. During the rotation, the telescopic rod 18 on the grinding body 11 is extended, so that the grinding stone 19 on the telescopic rod 18 contacts the workpiece 20, and the workpiece 20 is ground. The workpiece 20 is ground by moving the locking pin 4 through the lever 17.

[0023] As a preferred embodiment, the clamp body 1 is cylindrical, the through hole 2 is coaxial with the clamp body 1, and the slot 3 penetrates the upper and lower end faces of the clamp body 1.

[0024] After this setup, the workpiece 20 is inserted into the through hole 2, and then screwed into the screw hole 5 by screw 10, which reduces the width of the slot 3, thereby allowing the fixture body 1 to hold the workpiece 20.

[0025] As a preferred embodiment, the clamp body 1 has a first notch 6 on one side of the slot 3, and one end of the screw hole 5 extends from the first notch 6 to the outside of the clamp body 1. The purpose of providing the first notch 6 is to reduce the thickness of one side of the slot 3, so that the screw 10 can compress the width of the slot 3 after being screwed into the screw hole 5, thereby achieving the function of clamping the workpiece 20.

[0026] As a preferred embodiment, the inner wall of the through hole 2 is provided with a protrusion 7, which is parallel to the axis of the through hole 2. By providing the protrusion 7, the friction between the through hole 2 and the workpiece 20 can be increased during the clamping process.

[0027] As a preferred embodiment, a through hole 9 is provided radially between the two ends of the locking pin 4. By providing the through hole 9, the locking pin 4 can be moved by inserting the lever 17 into the through hole 9, thus preventing slippage.

[0028] As a preferred embodiment, a second notch 8 is provided between the two ends of the locking pin 4, and the inner surface of the second notch 8 has a smooth structure. The second notch 8 is also provided to prevent slippage when the lever 17 moves the locking pin 4.

[0029] As a preferred embodiment, the clamp body 1 is made of stainless steel. This makes the clamp body 1 more flexible.

[0030] A grinding machine using the above-mentioned grinding fixture includes a grinding machine body 11. A fixed seat 12 and a sliding seat 13 are respectively provided at opposite ends of the upper surface of the grinding machine body 11. The sliding direction of the sliding seat 13 faces the fixed seat 12. A first conical column 14 is rotatably mounted on the fixed seat 12, and a second conical column 15 is mounted on the sliding seat 13. The first conical column 14 and the second conical column 15 face each other and are coaxial. A rotating ring coaxial with the first conical column 14 is rotatably mounted on the fixed seat 12. 16. A lever 17 is fixedly mounted on the side of the rotating ring 16 facing the sliding seat 13. The lever 17 is parallel to the first conical column 14. The distance from the lever 17 to the axis of the first conical column 14 is less than the distance between the locking pin 4 and the center of the through hole 2. A grinding stone 19 is provided on the upper surface of the grinding machine body 11 via a telescopic rod 18. The telescopic direction of the telescopic rod 18 is perpendicular to the first conical column 14 and located between the first conical column 14 and the second conical column 15. When the rotating ring 16 rotates, a motor (not shown) is generally used. The motor is installed in the fixed seat. A first gear is coaxially mounted on the rotating ring 16, and a second gear meshing with the first gear is mounted on the output shaft of the motor, thus driving the rotating ring 16 to rotate.
