[0035] As shown in the figure, an integrated multi-core PTC heater heat sink assembly tooling has a main structure that adopts a conventional structure similar to a small punch press. The overall planning scheme is first to set two left and right support columns 4 fixedly supported on the ground in the vertical direction on the floor of the production workshop, and set a horizontal lower fixed partition 14 at the lower part of the space between the two support columns 4, and set a horizontal upper fixed partition 3 and a guide partition 5 at the upper part. The two ends of the upper fixed partition 3 are directly fixedly installed on the upper ends of the two support columns 4 through a pressure plate 31, and the two ends of the lower fixed partition 14 are fixedly supported and installed on the support columns on both sides through fixed support blocks 15 respectively. The two ends of the guide partition 5 are respectively slidably installed on the support columns 4 on both sides through guide sleeves 6, and the two ends of the guide partition move up and down along the support columns through the guide sleeves;

[0036] A fixed clamping plate 17 is fixedly installed above the lower fixed partition 14, and a movable clamping plate 12 is arranged in cooperation with the front side of the fixed clamping plate 17, and the multiple core tubes 20 of the multi-core PTC heater are clamped in parallel and limitedly by the movable clamping plate 12 and the fixed clamping plate 17; a pressing plate 2 is fixedly installed below the guide partition 5, and the front section of the pressing plate 2 is provided with multiple guide grooves penetrating up and down corresponding to the positions of the multiple core tubes 20, and the pressing plate 2 is fitted on each core tube 20 through each guide groove, and slides downward along each core tube 20 , press the heat sink 21, push it to be assembled on the core tube, so that the supporting column 4 constitutes a guide column structure; the width of the guide groove is larger than the width of the core tube 20, and smaller than the maximum width of the flanged boss of the heat sink of the multi-core PTC heater, so that the pressure plate can smoothly press the heat sink; a vertical cylinder 1 is fixedly installed in the vertical direction above the upper fixed partition 3, and after the telescopic rod of the vertical cylinder 1 passes through the upper fixed partition 3, the lower end is fixedly connected to the guide partition 5, and the vertical cylinder provides power for the guide partition to slide up and down.

[0037] Specifically, the front edge of the fixed clamping plate 17 is extended to the outside of the lower fixed partition 14, and a plurality of recessed slots 171 are provided. A plurality of plug blocks 121 are provided at positions corresponding to the slots 171 on the edge of the movable clamping plate 12. The outer side surface of one side of each plug block 121 and the corresponding inner side surface of the corresponding slot 171 constitute the lateral limiting clamping surfaces of the core tube 20. Each plug block 121 is inserted into the corresponding slot 171 to cooperate and clamp the core tube 20.

[0038] A horizontal guide plate 13 is fixedly connected to the front side of the lower fixed partition 14, and a horizontal cylinder 10 is fixedly installed above the guide plate 13. The rear end of the telescopic rod of the horizontal cylinder 10 is fixedly connected to the front side of the movable clamping plate 12.

Correspondingly, one outer side surface of the insert block 121 is the outer clamping surface of the core tube 20, and the other outer side surface is the guiding outer bevel. When the horizontal cylinder drives the movable splint to be inserted into the slot through the insert block, the insert block is inserted along the guiding inner bevel of the slot through the guiding outer bevel, so that the insert block has a tendency to clamp the core tube laterally while being inserted longitudinally. The structure is simple, stable and reliable, and easy to operate.

[0040] The longitudinal depth of the slot 171 is consistent with the width of the core tube 20. The rear side surface of the movable clamp 12 is located between adjacent plug blocks 121 and cooperates with the inner bottom surface of the slot 171 to form the longitudinal limiting surfaces on both sides of the core tube 20; the four sides of the core tube have limiting clamping surfaces, which further improves the reliability of clamping and positioning.

A positioning plate 7 is fixedly arranged above the middle fixed partition 8, and the front edge of the positioning plate 7 also extends to the outside of the middle fixed partition 8, and limiting grooves are arranged in number and position corresponding to the slots 171 on the fixed clamping plate 17, and the limiting grooves support the core tube through clearance fit; after the lower end of the core tube is inserted into the positioning groove through the electrode sheet, the middle part is then inserted into the limiting groove to improve the clamping balance performance, and at the same time, the upper surface of the positioning plate 7 can be used as the heat sink assembly positioning surface of the upper section of the core tube. When the first heat sink is slid and assembled from top to bottom along the core tube, it slides to the upper surface of the positioning plate 7 and stops in position, and the structure is simple and compact.

[0043] The guide groove of the front section of the pressing plate 2 is also arranged on the part of the entity extending from the front edge of the pressing plate 2 to the outside of the guide partition 3, and an upwardly concave process groove is arranged on the lower surface of the pressing plate 2 between adjacent guide grooves, so as to reduce weight and save energy;

[0044] Furthermore, a vertical bracket 19 is respectively arranged on the outer side of the left and right supporting columns 4, and an infrared safety protection grating 18 is respectively installed on the inner side of the upper section of the bracket 19, which is safe and reliable.

[0045] A vertical support column 16 is connected below the mounting plate, a transition connection block 11 is arranged on the front side of the movable clamping plate, and the rear end of the horizontal cylinder telescopic rod is fixedly connected to the transition connection block 11, so that the mechanical support is stable.

[0048] The second step is to position and place two heat sinks on the upper ends of the six core tubes respectively;

[0049] The third step is to start the vertical cylinder to drive the guide baffle to move downward, and the pressure plate moves downward along the core tube through the guide groove, pushing the two heat sinks to move downward along the six core tubes to the guide plate at the same time, and then driving the guide baffle and the pressure plate to reset;
