Description

Technical Field

[0001] This utility model belongs to the field of heat sink processing, specifically relating to a positioning fixture for liquid cooling heat sink processing. Background Technology

[0002] Liquid cooling heat sink machining positioning fixtures are specialized tooling equipment used to accurately position and fix liquid cooling heat sinks during machining processes such as milling, drilling, and welding. Their core function is to ensure machining accuracy, improve efficiency, and protect the structural integrity of the heat sink.

[0003] Existing heat sink processing positioning fixtures typically require placing the sheet material to be processed on a clamping platform and clamping and fixing it by pressing the jaws together. However, when clamping sheets with inclined edges, traditional positioning fixtures have difficulty fitting the clamping blocks according to the inclination angle of the sheet end face. When clamping inclined sheets, the fixture can only fit a portion of the sheet end face, which may cause the sheet to loosen during processing. When the inclined sheet end face is thin, single-point clamping may cause the sheet to deform, affecting the processing of the sheet. Utility Model Content

[0004] To overcome the problems of unstable clamping of inclined plates and potential damage to plates due to small clamping surface when using heat sink processing positioning fixtures, a liquid cooling heat sink processing positioning fixture is proposed.

[0005] The technical solution of this utility model is as follows: a liquid cooling heat sink processing positioning fixture, including a box and a support base. The support base is fixedly connected to the upper center of the box. Four electric cylinders are equidistantly distributed around the support base and fixedly connected to the upper inner wall of the support base. A movable plate is fixedly connected to the output end of the electric cylinder. A slide rail is fixedly connected to the front and rear ends and the center of the left and right ends of the support base. A sliding hole is opened through the movable plate near the support base. The sliding hole is adapted to the slide rail. A fixing block is fixedly connected to the upper end of the movable plate. A ball head is fixedly connected to the center of the fixing block near the support base. A ball cup is installed on the outer wall of the ball head. A clamping block is fixedly connected to the end of the ball cup near the support base. Two electric cylinders are fixedly connected to the upper edge of the box. Movable rods are fixedly connected to the output ends of the electric cylinders. Dovetail grooves are opened at the lower end of the movable rods and are symmetrically distributed in the front and back. A slider is slidably installed in the dovetail groove. A fixing rod is fixedly connected to the lower end of the front and rear sliders.

[0006] Furthermore, grooves are provided through the four corners of the upper end of the support base, and electric suction cups are fixedly connected in the grooves. A controller is installed at the lower end of the support base, and the controller is electrically connected to the electric cylinder.

[0007] Furthermore, a vacuum pump is fixed to the inner wall of the box, and the vacuum pump is connected to the air pipe of the electric suction cup.

[0008] Furthermore, a door is hinged at the front opening of the box, and the lower end of the clamping block is flush with the upper end of the electric suction cup.

[0009] Furthermore, the end of the clamping block furthest from the support is hinged with symmetrically distributed limiting rods, and the end of the fixing block closest to the support is provided with limiting holes, with the limiting rods and limiting holes being compatible.

[0010] Furthermore, symmetrical limiting sleeves are fixed to the upper edge of the housing, and a limiting post is fixed to the lower end of the movable rod, with the limiting post and the limiting sleeve being compatible.

[0011] Furthermore, the fixing rods correspond one-to-one with the support seats, and the lower end of the fixing rod is fixed with a rubber pad to the end of the clamping block near the support seat.

[0012] The beneficial effects of this utility model are as follows: The output end of the electric cylinder one can drive the movable plate to move along the slide rail, thereby allowing the clamping block to move closer to or away from the support seat. The ball head and ball cup can tilt the clamping block. The output end of the electric cylinder two can drive the movable rod to move up and down, allowing the fixed rod to move closer to or away from the support seat. Pushing the fixed rod causes it to move left and right along the dovetail groove. Compared with the existing heat sink processing positioning fixture, the added ball joint structure can offset the tilt angle of the clamping block when it clamps the plate, allowing the clamping block to fit against the end face of the plate, improving the clamping effect on plates with tilted end faces and avoiding damage to the plate. The added fixed rods can move away from or closer to each other along the dovetail groove. The movable rod can drive the fixed rod to move downward, allowing the fixed rod to fit against and press against the upper end of the plate, further improving the clamping effect on the plate.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-6 This utility model provides an embodiment of a liquid cooling heat sink processing positioning fixture, including a housing 1 and a support base 2. The support base 2 is fixedly connected to the center of the upper end of the housing 1. Four electric cylinders 6 are equidistantly distributed around the support base 2 and fixedly connected to the inner wall of the upper end of the support base 2. A movable plate 5 is fixedly connected to the output end of the electric cylinders 6. Slide rails 7 are fixedly connected to the center of the front and rear ends and the left and right ends of the support base 2. A sliding hole 8 is opened through the movable plate 5 near the support base 2. The sliding hole 8 is adapted to the slide rail 7. The upper end of the movable plate 5 is fixedly connected to... Fixed block 4, ball head 9 is fixedly connected to the center of one end of fixed block 4 near support base 2, ball cup 10 is installed on the outer wall of ball head 9, clamping block 3 is fixedly connected to one end of ball cup 10 near support base 2, electric cylinder 13 symmetrically connected to the upper edge of box 1, movable rod 14 is fixedly connected to the output end of electric cylinder 13 respectively, dovetail groove 15 symmetrically distributed in the left and right and front and back is opened at the lower end of movable rod 14, slider 16 is slidably installed in dovetail groove 15, and fixed rod 17 is fixedly connected to the lower end of the front and rear slider 16.

[0022] The output end of electric cylinder 6 can drive the movable plate 5 to move along the slide rail 7, thereby moving the clamping block 3 closer to or away from the support seat 2. The ball head 9, in conjunction with the ball cup 10, can tilt the clamping block 3, which can better fit the plate with an inclined end face and increase the contact area between the clamping block 3 and the plate. The output end of electric cylinder 13 can drive the movable rod 14 to move up and down, which can move the fixed rod 17 closer to or away from the support seat 2. Pushing the fixed rod 17 can move the fixed rod 17 left and right along the dovetail groove 15, which can adjust the spacing between the fixed rods 17, making it easier to press and clamp the plate, improving the clamping effect of the plate and avoiding damage to the plate.

[0023] Please see Figure 3In this embodiment, slots are provided through the four corners of the upper end of the support base 2. An electric suction cup 20 is fixedly connected to the slots at the upper end of the support base 2. A controller is installed at the lower end of the support base 2. The controller is electrically connected to the electric cylinder 6. In use, the slots in the support base 2 can provide installation space for the electric suction cup 20. The controller can synchronously control the electric cylinder 6. A vacuum pump 21 is fixedly connected to the inner wall of the housing 1. The vacuum pump 21 is connected to the air pipe of the electric suction cup 20. In use, the vacuum pump 21 can evacuate the electric suction cup 20, so that the electric suction cup 20 can adsorb and fix the plate.

[0024] Please see Figures 2-6 In this embodiment, a door is hinged to the front opening of the box 1, and the lower end of the clamping block 3 is flush with the upper end of the electric suction cup 20. When in use, the box 1 can be opened through the door to facilitate maintenance of the equipment inside the box 1. The end of the clamping block 3 away from the support base 2 is hinged with symmetrically distributed limiting rods 12. The end of the fixing block 4 near the support base 2 is provided with a limiting hole 11. The limiting rod 12 is adapted to the limiting hole 11. When in use, the outer wall of the limiting rod 12 slides against the inner wall of the limiting hole 11, which can improve the stability of the movement of the clamping block 3.

[0025] Please see Figure 6 In this embodiment, a symmetrically positioned limiting sleeve 19 is fixedly connected to the upper edge of the housing 1. A limiting post 18 is fixedly connected to the lower end of the movable rod 14. The limiting post 18 is adapted to the limiting sleeve 19. In use, the movable rod 14 can move up and down by the limiting post 18 in conjunction with the limiting sleeve 19, which can improve the stability of the up and down movement of the movable rod 14. The fixed rod 17 corresponds one-to-one with the support base 2. A rubber pad is fixedly connected to the lower end of the fixed rod 17 and the end of the clamping block 3 near the support base 2. In use, the rubber pad fixed to the clamping block 3 and the fixed rod 17 can prevent damage to the plate during clamping.

[0026] During operation, firstly, place the plate to be fixed on the upper part of the support base 2, adjust the position of the plate, and preliminarily adjust the tilt angle of the clamping block 3 according to the tilt angle of the plate end face, so that the clamping block 3 is as parallel as possible to the tilt angle of the end face. Start the four electric cylinders 6 through the controller, so that the controller controls the output end of the electric cylinder 6 to retract and drive the clamping block 3 close to the end face of the plate. Then, wait for the clamping block 3 to fit against the four sides of the plate and stabilize, and then turn off the electric cylinder 6. Then, start the vacuum pump 21 and wait for the vacuum pump 21 to evacuate the electric suction cup 20 to complete the fixation of the lower end of the plate. Finally, according to the width of the plate, push the fixing rod 17 along the dovetail groove 15, adjust the spacing of the fixing rod 17, start the electric cylinder 13, wait for the output end of the electric cylinder 13 to retract and drive the fixing rod 17 to fit against and press the plate, and then turn off the electric cylinder 13 to complete the clamping and fixing of the plate.

[0027] Through the above steps, the output end of electric cylinder 6 can drive the movable plate 5 to move along the slide rail 7, thereby moving the clamping block 3 closer to or away from the support seat 2. The ball head 9, in conjunction with the ball cup 10, can tilt the clamping block 3, increasing the contact area between the clamping block 3 and the plate. The output end of electric cylinder 13 can drive the movable rod 14 to move up and down, allowing the fixed rod 17 to move closer to or away from the support seat 2. Pushing the fixed rod 17 causes it to move left and right along the dovetail groove 15, adjusting the spacing between the fixed rods 17. This solves the problem that the heat sink processing positioning fixture is unstable when clamping plates with tilted end faces, and that the small clamping surface may damage the plates.
