[0003] The existing positioning fixture clamps the two ends of the heat dissipation stamping part by rotating the studs, and the positioning effect is general. The vibration during the grinding process can easily loosen the heat dissipation stamping part. The excessive clamping force at both ends causes the heat dissipation stamping part to deform, affecting the workpiece processing quality. Utility Model Content

[0006] Furthermore, the limiting assembly includes a connecting ring and a positioning plate, the connecting ring is threadedly connected to the outer side walls of the positive and negative studs, the connecting rings are distributed at both ends of the positive and negative studs, the connecting rings are symmetrically arranged, the positioning plate is fixedly connected to the upper part of the connecting ring, and the positioning plate is arranged in an isosceles trapezoid.

[0007] Furthermore, the clamping assembly includes a cylinder, an adjustment plate and a rotating baffle, the cylinder passes through the sleeve and is fixedly connected inside the sleeve, the adjustment plate is fixedly connected to the symmetrical telescopic end of the cylinder, and the rotating baffle is rotatably connected to one end of the cylinder away from the telescopic end.

[0008] Furthermore, a limiting plate is fixedly connected between the symmetrical opposite side walls of the sleeve, the limiting plate is symmetrically arranged with the positive and negative studs as the center, and the upper wall of the limiting plate is in contact with the bottom wall of the positioning piece.

[0009] Furthermore, a through hole is opened inside the rotating baffle.

[0010] After adopting the above structure, the beneficial effects of the utility model are as follows: for the assembled stamped heat sink, the bottom of its two ends or the bottom of the middle position are limited, and the freedom of its left and right directions is limited by the rotationally adjustable limit component. It can also be suitable for clamping stamped heat sinks of different widths, and then the front and rear directions of the stamped heat sink are automatically limited by the clamping component to achieve clamping of the bottom of the stamped heat sink, thereby improving the positioning effect during processing.

[0016] like Figure 1-3 As shown, a positioning jig for rotary grinding of heat dissipation stamping parts comprises positive and negative studs 1 and a sleeve 2. The sleeve 2 can be rotatably connected to the two end surfaces of the positive and negative studs 1. The sleeve 2 is symmetrically arranged with the positive and negative studs 1 as the center. It also comprises a limiting component 3 and a clamping component 4. The limiting component 3 is movably connected to the outer side walls of the positive and negative studs 1. As the positive and negative studs 1 rotate, the limiting component 3 moves in opposite directions for adjustment, and is used for axially limiting the heat dissipation stamping parts evenly spaced apart on the positive and negative studs 1. The clamping component 4 passes through the sleeve 2 and is movably connected to the two ends of the sleeve 2, and is used for axially clamping the heat dissipation stamping parts perpendicular to the positive and negative studs 1.

[0017] like Figure 1As shown, in order to limit different positions of the bottom of the stamped heat sink, the limiting assembly 3 includes a connecting ring 5 and a positioning piece 6. The connecting ring 5 is threadedly connected to the outer side wall of the positive and negative studs 1. The connecting rings 5 ​​are distributed at both ends of the positive and negative studs 1. The connecting rings 5 ​​are symmetrically arranged. The positioning piece 6 is fixedly connected to the upper part of the connecting ring 5. The positioning piece 6 is arranged in an isosceles trapezoid. By rotating the connecting ring 5, the symmetrical connecting rings 5 ​​move in opposite directions, and the position of the positioning piece 6 is adjusted so that the positioning piece 6 can be inserted into the middle of the bottom of the stamped heat sink or both sides of the bottom, so as to limit the left and right movement of the stamped heat sink.

[0018] In order to increase the movement stability of the positioning piece 6 and support the heat dissipation stamping part, a limiting plate 10 is fixedly connected between the opposite side walls of the symmetrical sleeve 2. The limiting plate 10 is symmetrically arranged with the positive and negative studs 1 as the center, and the upper wall of the limiting plate 10 contacts the bottom wall of the positioning piece 6.

[0019] like Figure 3 As shown, in order to further limit the stamped heat sink, the clamping assembly 4 cooperates with the limiting assembly 3 to achieve the positioning of the stamped heat sink. The cylinder 7 passes through the sleeve 2 and is fixedly connected to the sleeve 2. The adjusting plate 8 is fixedly connected to the symmetrical telescopic end of the cylinder 7. The rotating baffle 9 is rotatably connected to the end of the cylinder 7 away from the telescopic end. The cylinder 7 is telescopically adjusted to drive the adjusting plate 8 to move, pushing one side of the stamped heat sink toward the side of the rotating baffle 9, positioning the stamped heat sink between the rotating baffle 9 and the adjusting plate 8, and realizing the positioning processing of the stamped heat sink.

[0020] A through hole 11 is provided inside the rotating baffle 9, and the rotating baffle 9 can be rotated and adjusted. The through hole 11 inside the rotating baffle 9 can also be used to realize bolt connection and installation of the device, so as to assemble, connect and fix the device.

[0021] During specific use, the operator rotates the positive and negative studs 1 to adjust the position of the symmetrical positioning plates 6, so that the symmetrical positioning plates 6 are inserted into the gap between the bottom of the assembled stamped heat sink, limiting the freedom of the stamped heat sink in the left and right directions, and driving the symmetrical cylinders 7 to contract, so that the adjustment plate 8 contacts one side of the stamped heat sink, pushing it to slide along the length direction of the positioning plate 6 and contacting the rotating baffle 9, so that the stamped heat sink is clamped between the rotating baffle 9 and the adjustment plate 8, limiting the freedom of the stamped heat sink in the front and back directions, and realizing the bottom clamping and positioning of the stamped heat sink.

[0022] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents.
