Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the vehicle radiator quick positioning welding fixture provided in this embodiment includes a base 1, an L-shaped support platform 2 is installed on the base 1, and a worktable 3 and a side positioning mechanism 16 are installed on the transverse table surface of the support platform 2.

[0029] Two slide blocks 5 are symmetrically installed on the worktable 3 along its length direction. A porous flexible positioning platform 6 is provided above the worktable 3. The bottom of the porous flexible positioning platform 6 is formed with sliders that slide and cooperate with the two slide blocks 5 respectively, so that the porous flexible positioning platform 6 can reciprocate along the length direction of the worktable 3 through the cooperation of the sliders and the slide blocks 5, that is, the porous flexible positioning platform 6 can move along the X-axis direction on the worktable 3.

[0030] The porous flexible positioning platform 6 has a sliding mounting groove along the length of the worktable 3. A threaded rod 7 is installed in the sliding mounting groove along its length. The two ends of the threaded rod 7 are fixed to the inner walls of the sliding mounting groove by bearings. The threaded rod 7 can rotate in the sliding mounting groove by bearings. A sleeve 8 with its threaded engagement is also fitted on the threaded rod 7. The upper part of the sleeve 8 is located in the sliding mounting groove and there is a gap between it and the inner wall of the sliding mounting groove. The bottom of the sleeve 8 is fixedly connected to the surface of the worktable 3. Therefore, when the threaded rod 7 rotates, since the sleeve 8 is fixed to the surface of the worktable 3, that is, the sleeve 8 does not move, the threaded rod 7 is displaced along the length of the sleeve 8. At the same time, the porous flexible positioning platform 6 is displaced along the length of the worktable 3 by the slider and the slide block 5 at the bottom of the porous flexible positioning platform 6.

[0031] Therefore, in order to enable the porous flexible positioning platform 6 to achieve displacement in the X-axis direction, a worm gear mechanism 9 is installed at one end of the threaded rod 7. The worm gear mechanism 9 adopts existing mature worm gear technology, including a worm wheel and a worm. The worm wheel is fixedly fitted at one end of the threaded rod 7, the worm is perpendicular to the threaded rod 7, and one end of the worm meshes with the worm wheel. The other end of the worm extends out of the edge of the porous flexible positioning platform 6 and is equipped with an adjusting turntable 10. By manually rotating the adjusting turntable 10, the adjusting turntable 10 drives the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the worm fixedly fitted with it to rotate. The worm achieves displacement through the sleeve 8 that is threaded with it, thereby realizing the displacement control of the porous flexible positioning platform 6 in the X-axis direction by adjusting the turntable 10.

[0032] The porous flexible positioning platform 6 has four positioning clamps 11 arranged in a square on its surface. Each of the four positioning clamps 11 has an installation platform formed at its bottom. Each installation platform has four installation holes arranged in a square. The installation holes match the fixing holes on the porous flexible positioning platform 6, so that the positioning clamps 11 can be quickly installed and removed from the porous flexible positioning platform 6.

[0033] Each of the positioning clamping seats 11 has a support seat 12 formed on one side of the mounting platform at the bottom. Each positioning clamping seat 11 has a top surface pressing mechanism 13 fixedly installed on the rear side. The top surface pressing mechanism 13 includes a mounting seat, a top surface pressing cylinder, and a pressing component. The mounting seat is fixed on the upper part of the positioning clamping seat 11, and the top surface pressing cylinder is fixed on the bottom of the mounting seat. The mounting seat is hollow inside, and the telescopic rod of the top surface pressing cylinder is located inside the mounting seat. The pressing component is hinged to the mounting seat through a hinge. The telescopic rod of the top surface pressing cylinder is connected to the hinge through a connector. The pressing component can be flipped up and pressed down by the extension and retraction of the telescopic rod of the top surface pressing cylinder. After the pressing component is pressed down, it corresponds to the support seat 12 on the positioning clamping seat 11.

[0034] Among them, two positioning clamping seats 11 located on the same side of the workbench 3 along the length direction are equipped with positioning blocks 14 on the inner side wall near the support seat 12. On the other two positioning clamping seats 11 on the same side, corresponding to the positioning blocks 14, side clamping mechanisms 15 are installed. The side clamping mechanism 15 includes a side clamping cylinder and a clamping seat. The clamping seat corresponds to the positioning hole. Both the support block and the positioning hole are conductive.

[0035] By integrating the top pressing mechanism 13, the side pressing mechanism 15, the support base 12 and the positioning block 14 onto the positioning clamping base 11, a positioning clamping base 11 can still have the function of positioning and clamping the workpiece after being quickly assembled on the multi-hole flexible positioning platform 6, thus enabling it to be used to clamp radiators within a certain length and width range.

[0036] The side positioning mechanism 16 includes a lifting base 1601, a lifting cylinder 1602, a lifting plate 1603, and a lifting rod 1604. Two lifting bases 1601, two lifting cylinders 1602, two lifting plates 1603, and two lifting rods 1604 are provided. Two lifting bases 1601 are symmetrically installed on both sides of the support platform 2. An adjusting groove 1607 is provided on the support platform 2 at the bottom of the lifting base 1601. An adjusting roller 1606 is provided within the adjusting groove 1607 and slides within it. The adjusting roller 1606 is connected to the bottom of the lifting base 1601 via a rotating shaft. A fixing screw 1608 is provided on the side wall of the lifting base 1601. Several connecting holes 1609 are provided on the side wall of the support platform 2 along the length of the support platform 2, corresponding to the height of the fixing screw 1608. The lifting base 1601 is fixed to the side wall of the support platform 2 by connecting the fixing screw 1608 to the connecting holes 1609. A lifting rod 1604 is installed through one side of the lifting fixed seat 1601, and the bottom of the other side is fixedly connected to the lifting cylinder 1602. The telescopic rod of the lifting cylinder 1602 passes through the lifting fixed seat 1601. The lifting rod 1604 is slidably engaged with the lifting fixed seat 1601. Connecting seats 1605 are formed on both sides of the lifting plate 1603. The two lifting plates 1603 are arranged vertically aligned. One of the connecting seats 1605 located on both sides of the same end of the lower lifting plate 1603 is fixedly connected to the end of the telescopic rod of the lifting cylinder 1602, and the other connecting seat 1605 is fitted on the lifting rod 1604 and is slidably engaged with the lifting rod 1604. The connecting seats 1605 located on the upper lifting plate 1603 and the corresponding lifting rod 1604 are fixedly connected to the end of the lifting rod 1604. The lifting rods 1604 and the lifting cylinder 1602 of the two lifting fixed seats 1601 are distributed in an X-shape.

[0037] Limiting wheels 17 are respectively installed on the two end surfaces of the two lifting plates 1603, and the limiting wheels 17 are located on the side close to the porous flexible positioning platform 6;

[0038] An infrared calibration mechanism 18, adjustable along the direction of the support rod 4, is also installed at the end of the support rod 4 on the vertical platform of the support platform 2. The infrared calibration mechanism 18 includes a support guide rail 1801 and a sliding seat 1802 that slides with the support guide rail 1801. An infrared calibrator 1803 is installed on the surface of the sliding seat 1802. An adjusting screw 1804 that is threadedly connected to the bottom of the sliding seat 1802 is threaded through it. One end of the adjusting screw 1804 is rotatably fixed to the inner wall of the end of the support guide rail 1801, and the other end extends out of the support guide rail 1801 and is connected to an adjusting knob 1805. The calibration light of the infrared calibrator 1803 is directed between the porous flexible positioning platform 6 and the side positioning mechanism 16.

[0039] In use, the positions of the four positioning clamping seats 11 on the multi-hole flexible positioning platform 6 are roughly adjusted according to the size of the heat sink to be processed. After the adjustment is completed, the lifting plate 1603 of the side positioning mechanism 16 is raised, and the workpiece is placed on the support seat 12 of the four positioning clamping seats 11. The workpiece is positioned by the limiting stop wheel 17 on the raised lifting plate 1603 in the X-axis direction and by the positioning block 14 in the Y-axis direction. After the positioning is completed, the top pressing mechanism 13 and the side pressing mechanism 15 work to press the workpiece. Then the side positioning mechanism 16 is lowered, and the infrared rays emitted by the infrared calibrator 1803 are observed to be aligned with the weld. If they are not aligned, the multi-hole flexible positioning platform 6 is finely adjusted in the X-axis direction by rotating the adjusting turntable 10 so that the infrared rays emitted by the infrared calibrator 1803 are aligned with the weld, thus completing the clamping and starting automatic welding.

Any modifications and substitutions based on the technical solutions and utility model concepts provided by the present utility model should be covered within the protection scope of the present utility model.
