[0028] like Figure 1 As shown in Figure 14, a clamping device for grinding long shaft parts includes a body 1, a sleeve 2, a bushing 5, an indexing plate 6, a knurled handle 7, a clamping rod 11, a spring B12, and a clamping sleeve 14. The body 1 includes a support 101 and a square iron 102. The support 101 is L-shaped and fixed at the right end of the top of the square iron 102. The vertical part of the support 101 protrudes from the top of the square iron 102. A horizontal sleeve 2 is installed on the left side inside the square iron 102, and a horizontal bushing 5 is installed on the right side inside the square iron 102. An indexing plate 6 is installed in the bushing 5. The outer circle of one end of the indexing plate 6 has six notches, and the inner circle has two keyways. The outer circle of one end of the indexing plate 6 is exposed outside the square iron 102, and the outer circle of this end of the indexing plate 6 is located below the vertical part of the support 101.

[0029] A vertically oriented positioning pin 9 is installed in the support 101 of the main body 1. A knurled handle 7 is installed on the upper part of the positioning pin 9. The positioning pin 9 and the knurled handle 7 are fixed by a cylindrical pin 8. A clamping rod 11 and a clamping sleeve 14 are installed in the middle position inside the square iron 102. A spring B12 is installed inside the square iron 102 between the head of the clamping rod 11 and the clamping sleeve 14. The rod body of the clamping rod 11 passes through the spring B12 and the clamping sleeve 14. The end of the rod body of the clamping rod 11 is threadedly connected to the star-shaped handle 3. The arrangement direction of the clamping rod 11 and the clamping sleeve 14 is perpendicular to the direction of the long shaft-like parts. The adjacent bottom positions of the clamping rod 11 and the clamping sleeve 14 can clamp the top two sides of the long shaft-like parts. On the side of the star-shaped handle 3, a screw a4 is threadedly connected to the square iron 102.

[0030] The support 101 contains a spring A10. The shaft part of the positioning pin 9 passes through the spring A10. The spring A10 is located above the pin part of the positioning pin 9. The pin part of the positioning pin 9 can be inserted into any notch of the indexing plate 6.

[0031] Above the clamping rod 11 and above the clamping sleeve 14, two spaced screws b13 are threaded onto the square iron 102; a waist-shaped groove is provided on the head of both the clamping rod 11 and the clamping sleeve 14, and the ends of the two screws b13 are pressed against the corresponding waist-shaped grooves on their respective sides.

[0032] During use, the main body 1, star-shaped handle 3, indexing plate 6, knurled handle 7, positioning pin 9, clamping rod 11, and clamping sleeve 14 are all variable structures. During machining, long shaft-type parts are placed in sleeve 2 and indexing plate 6. These long shaft-type parts have a spline structure, with the splined portion positioned in two keyways within the inner circle of indexing plate 6. The machining position of the part can be adjusted by matching the keyway position with indexing plate 6. The pin portion of positioning pin 9, under the action of spring A10, engages with a corresponding notch on indexing plate 6 to position indexing plate 6. After the position is adjusted and fixed, screw a4 is tightened so that the end of screw a4 passes through the bushing 5. The indexing plate 6 is fixed by passing through the hole and pressing it against it. Then, the star handle 3 is rotated, which drives the clamping rods 11 and clamping sleeves 14 on both sides of the part to move towards the shaft of the part. The star handle 3 tightens the clamping rods 11 and clamping sleeves 14. The bottom positions of the adjacent clamping rods 11 and clamping sleeves 14 clamp the top two sides of the long shaft part, fixing the workpiece and preventing it from rotating. Then, the clamping rods 11 and clamping sleeves 14 are tightened with two screws b13 to complete the clamping and fixing of the long shaft part. The positioning fixture device has the main body 1 as the main structure and the indexing plate 6, positioning pin 9 and clamping rod 11 as auxiliary structures, which effectively realizes the rapid clamping of long shaft parts.
