Description

Technical Field

[0001] This utility model relates to the field of SMC insulation board processing technology, and in particular to a device for pinpoint punching of SMC insulation boards. Background Technology

[0002] SMC insulation boards are mainly made of unsaturated resin, low-shrinkage additives, fillers, and other additives. They also feature low water absorption, dimensional stability, and minimal warping, which can solve the shortcomings of wooden, steel, and plastic meter boxes, such as easy aging, easy corrosion, poor insulation, and short lifespan.

[0003] A search revealed that CN216543696U discloses a device for precisely positioning and fixing SMC insulation boards. This utility model provides a device for precisely positioning and fixing SMC insulation boards. The device includes: a first support frame; the first support frame is located on the top of the lower part of the left and right sides of the support base; a placement frame, with square grooves on both the left and right sides of the upper inner side of the first support frame, and the placement frame slidingly disposed within these square grooves; and a first handle, located on the front wall of the placement frame. When the operator activates a cylinder, the cylinder moves a pressure block, and the punching tubes on the left and right sides of the bottom of the pressure block punch holes in the SMC insulation board.

[0004] When this technical solution is used, the punch tube and the pressure block are integrated into a single structure and set at the output end of the cylinder. Under long-term use, the friction between the punch tube and the plate will cause the punch tube to wear, which will gradually reduce the diameter of the punch tube, affecting the dimensional accuracy and quality of the punching. It is also very inconvenient to replace it easily.

[0005] To address this, we propose a device for pinpoint punching of SMC insulation boards. Utility Model Content

The top of the punching tube has a connecting part for installation with the connecting groove and the snap-fit ​​block, and the connecting part includes a connector located at the top axial position of the punching tube.

[0008] Furthermore, both ends of the connecting groove are provided with sliding grooves, and the snap-fit ​​block is slidably connected to the inner wall of the sliding groove. The snap-fit ​​block has an arc-shaped structure, the connector head is adapted to the connecting groove, the first protrusion and the first groove are adapted to each other, and the snap-fit ​​block and the snap-fit ​​groove are adapted to each other.

[0009] Furthermore, a first bevel gear is fixedly connected to the bottom axial position of the rotating shaft, and rotating holes are opened at both ends of the rotating shaft. A first lead screw is rotatably connected to the inner wall of the rotating hole. A second bevel gear is fixedly connected to the axial position of the first lead screw near the rotating shaft. The first bevel gear and the second bevel gear mesh with each other. An adjusting rod is threaded to the outer wall of the first lead screw and slidably connected to both ends of the pressure block.

[0027] Example 1: A device for punching holes at specific points on an SMC insulating board, such as... Figure 1 As shown, the punching equipment includes a main body, which comprises a support base 1, a support frame 2, a placement frame 3, a cylinder 4, a pressure block 5, and a punching tube 6. The support frame 2 is fixedly connected to the top of the support base 1, with sliding grooves at both ends. The placement frame 3 has guide rails at both ends, which are slidably connected to the inner wall of the sliding grooves. The top of the placement frame 3 has a placement slot for placing sheet metal, with through slots at both ends. A handle for pulling is provided on the outer wall of the placement frame 3. The cylinder 4 is fixedly connected to the top of the support frame 2 via a motor frame. On the opposite wall, the pressure block 5 is set at the output end of the cylinder 4, and the punching tube 6 is set at the bottom of the pressure block 5 and located in the axial position of the through groove. (The part in parentheses is the prior art, which will not be elaborated here.) When punching is required, pull the handle on the placement frame 3. At this time, the placement frame 3 is pulled out by sliding in the slide groove through the guide rail on it, and the plate is placed into the placement groove on it. Then, push the placement frame 3 to the end by the handle. At this time, the cylinder 4 is turned on. The cylinder 4 starts and drives the pressure block 5 to rise and fall, and then drives the punching tube 6 to rise and fall to punch the plate.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, the bottom of the pressure block 5 has connecting grooves 13 at both ends, and fixing components for installation are provided at both ends of the connecting grooves 13. The fixing components include snap-fit ​​blocks 14 that are slidably connected to both ends of the connecting grooves 13. The fixing components also include a first knob 7, a rotating shaft 15, a first lead screw 16, and an adjusting rod 17 for adjusting the position of the snap-fit ​​blocks 14. The first knob 7 is located at the top of the pressure block 5, the rotating shaft 15 is located at the bottom axial position of the first knob 7, and the first lead screw 16 is located at both ends of the rotating shaft 15. A first bevel gear 18 and a second bevel gear 19 that mesh with each other are provided at the axial positions close to the rotating shaft 15 and the first lead screw 16. The adjusting rod 17 is slidably connected to both ends of the inner wall of the pressure block 5 and threadedly connected to the first lead screw 16. The lead screw 16 is fixedly connected to the outer wall of the adjusting rod 17 on one side of the snap-fit ​​block 14. The rotating shaft 15 is driven to rotate by the first knob 7, and the first bevel gear 18 and the second bevel gear 19 mesh with each other to drive the first lead screw 16 to rotate, which in turn drives the adjusting rod 17 threaded on it to move. The movement of the adjusting rod 17 can drive the snap-fit ​​block 14 to move. The top of the punched tube 6 is provided with a connecting part that is installed with the connecting groove 13 and the snap-fit ​​block 14. The connecting part includes a connector 9 located at the axial position of the top of the punched tube 6. The connector 9 has snap-fit ​​grooves 10 at both ends. The connector 9 is inserted into the connecting groove 13, and the snap-fit ​​block 14 is snapped into the snap-fit ​​groove 10 on the connector 9 to fix the first knob 7.

[0029] like Figure 3 , Figure 5 and Figure 6As shown, both ends of the connecting groove 13 are provided with sliding grooves, and the snap-fit ​​block 14 is slidably connected to the inner wall of the sliding groove. The snap-fit ​​block 14 has an arc-shaped structure. The connecting groove 13 and the sliding groove are provided with first grooves at their opposite ends. The connector 9 is provided with first protrusions at both ends. The connector 9 is adapted to the connecting groove 13, the first protrusions are adapted to the first grooves, and the snap-fit ​​block 14 is adapted to the snap-fit ​​groove 10.

[0030] A first bevel gear 18 is fixedly connected to the bottom axial position of the rotating shaft 15. Rotating holes are opened at both ends of the rotating shaft 15. A first lead screw 16 is rotatably connected to the inner wall of the rotating hole, and a second bevel gear 19 is fixedly connected to the first lead screw 16 at the axial position near the end of the rotating shaft 15. An adjusting rod 17 is threaded to the outer wall of the first lead screw 16 and slidably connected to both ends of the pressure block 5.

[0031] When the perforated tube 6 needs to be installed, the connector 9 on the perforated tube 6 is inserted into the connecting groove 13. At this time, the insertion direction of the connector 9 is limited by the insertion of the first protrusion and the first groove. Then, the first knob 7 is rotated. The first knob 7 drives the first bevel gear 18 to rotate through the rotating shaft 15, and then drives the second bevel gear 19 meshing with it to rotate. The second bevel gear 19 can then drive the adjusting rod 17 threadedly connected to the first lead screw 16 to slide. The movement of the adjusting rod 17 causes the locking blocks 14 on both sides to move closer and lock into the locking groove 10 on the connector 9 for fixation. When disassembly is required, simply rotate the first knob 7 in the opposite direction, and then drive the locking blocks 14 to move out of the locking groove 10, so that the perforated tube 6 can be pulled out.

[0032] The fixed components and connecting parts allow for easy installation and disassembly of the perforated tube 6. When the perforated tube 6 is damaged, it can be easily replaced, preventing the perforated tube 6 from gradually wearing down over a long period of use, which would cause the diameter of the perforated tube 6 to decrease and affect the dimensional accuracy and quality of the punching.

[0033] like Figure 4 , Figure 7 and Figure 8 As shown, the top and bottom of the snap-fit ​​block 14 are provided with multiple sliding holes arranged in a circular pattern. The inner wall of the sliding hole is slidably connected to the insertion rod 23. Both ends of the inner wall of the snap-fit ​​groove 10 are provided with insertion cavities 11. The insertion rod 23 is adapted to the insertion cavity 11. The inner wall of the insertion cavity 11 is provided with multiple elastic rings 12 arranged in a linear pattern. The elastic ring 12 has a circular ring structure. The insertion rod 23 is inserted into the insertion cavity 11 to further fix the connector 9 and squeeze the elastic ring 12. The elastic ring 12 is squeezed and deformed to fill the gap between the insertion rod 23 and the insertion cavity 11, thereby increasing the friction between the two.

[0034] A through hole is provided on one side of the snap-fit ​​block 14, which extends to the outer wall of the pressure block 5. A sliding seat 20 and a second lead screw 21 are provided in the through hole. A second knob 8 for adjustment is fixedly connected to one end of the sliding seat 20 at an axial position.

[0035] The inner walls on both sides of the sliding seat 20 are provided with second grooves, and the outer walls of the second lead rod 21 are provided with second protrusions at both ends. The second protrusions are slidably connected to the inner walls of the second grooves. One end of the second lead rod 21 passes through the through hole and is rotatably connected to the inner wall of the snap-fit ​​block 14. The design of the second protrusion and the second groove can limit the relative rotation between the sliding seat 20 and the second lead rod 21, and the second lead rod 21 can rotate synchronously with the sliding seat 20.

[0036] A pressing block 22 is slidably connected to the inner wall of the snap-fit ​​block 14. The cross-sections of the upper and lower ends of the pressing block 22 are inclined, and a through threaded hole is opened in the pressing block 22. The second lead screw 21 is threadedly connected to the inner wall of the threaded hole.

[0037] A pressure block 25 is fixedly connected to one end of the plug rod 23 near the extrusion block 22. The cross-section of the pressure block 25 is inclined and fits against the extrusion block 22. A return spring 24 is provided on the wall surface opposite to the pressure block 25 and the snap-fit ​​block 14. The return spring 24 is sleeved on the outer wall of the plug rod 23.

[0038] When the locking block 14 moves into the locking groove 10 and engages, the second lead screw 21 moves synchronously with the locking block 14 and slides within the sliding seat 20. At this time, rotating the second knob 8 causes the pressing block 22, which is threaded onto the sliding seat 20 and the second lead screw 21, to slide within the locking block 14. The pressing block 22 moves and presses against the pressure block 25 through its inclined surface. The insertion rod 23 on the pressure block 25 is slidably connected to the sliding hole. The pressing against the pressure block 25 causes the insertion rod 23 to move and be inserted into the insertion cavity 11 on the locking groove 10 for fixation. When disassembly is required, simply rotate the second knob 8 in the opposite direction to move the pressing block 22 in the opposite direction. At this time, under the elastic force of the return spring 24, the insertion rod 23 can be moved out of the insertion cavity 11.

[0039] The elastic ring 12 and the plug rod 23 are designed to withstand the stress at the connection point in multiple directions through the insertion of the plug rod 23, thereby improving the stability of the connection point. Furthermore, the elastic ring 12 can increase the friction between the plug rod 23 and the plug cavity 11, further enhancing the stability of the connection point.

[0040] The working principle of this utility model is as follows: When punching is required, pull the handle on the placement frame 3. At this time, the placement frame 3 is pulled out by sliding in the groove through the guide rail on it, and the plate is placed into the placement groove on it. Then, push the placement frame 3 to the end by using the handle. At this time, the cylinder 4 is activated. The cylinder 4 drives the pressure block 5 to rise and fall, and then drives the punching tube 6 to rise and fall to punch the plate. When the punching tube 6 needs to be installed, the connector 9 on the punching tube 6 is inserted into the connecting groove 13. At this time, the insertion direction of the connector 9 is limited by the insertion of the first protrusion and the first groove. Then, turn the first knob 7. The first knob 7 drives the first bevel gear 18 to rotate through the rotating shaft 15, and then drives the second bevel gear 19 meshing with it to rotate. The second bevel gear 19 can drive the adjusting rod 17 threadedly connected to the first lead screw 16 to slide. The movement of the adjusting rod 17 causes the locking blocks 14 on both sides to move closer and lock into the connector 9. The locking block 14 is fixed in the locking groove 10. When the locking block 14 moves into the locking groove 10 and locks in, the second screw 21 moves synchronously with the locking block 14 and slides in the sliding seat 20. At this time, the second knob 8 is turned. The second knob 8 can drive the pressing block 22 threaded on it to slide in the locking block 14 through the sliding seat 20 and the second screw 21. The pressing block 22 can press the pressure block 25 through its inclined surface. The insertion rod 23 on the pressure block 25 is slidably connected in the sliding hole. The pressing of the pressure block 25 can drive the insertion rod 23 to move and insert into the insertion cavity 11 on the locking groove 10 for fixation. When disassembly is required, the second knob 8 is turned in the opposite direction to drive the pressing block 22 to move in the opposite direction. At this time, under the action of the return spring 24, the insertion rod 23 can be moved out of the insertion cavity 11. The first knob 7 is turned in the opposite direction to drive the locking block 14 to move from the locking groove 10, so that the punch tube 6 can be pulled out.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
