[0014] (III) Beneficial effects

[0015] The utility model provides a clamping tool for a self-drilling screw forming die, which has the following beneficial effects:

[0016] (1) The motor drives the rotation of the bidirectional threaded rod, and the clamp plate performs bidirectional movement under the action of the bidirectional threaded rod, and the stability of the movement direction is ensured by the positioning rod. The inner cavity design of the clamp plate enables the fixed column and spring 1 to be correctly placed. The elastic action of spring 1 enables the clamp plate to generate appropriate reaction force when it moves. The design of the sliding block plays an important role in the clamping process. The roller on the sliding block reduces friction and improves the clamping effect. At the same time, the movement of the sliding block is also controlled by the movement of the clamp plate, ensuring stable operation. The coordination of these structures achieves the effect of clamping different molds, solves the problem of mold clamping and positioning in industrial production, and improves production efficiency.

[0017] (2) The sliding block is connected to the connecting block through a sliding groove, and a top block and a damper are installed on the connecting block. When the sliding block moves, the connecting block moves in the sliding groove, and through the cooperation of the top block and the damper, a damping effect is generated when an external force is applied, thereby slowing down the speed of the sliding block. At the same time, the elastic effect of spring 2 works in coordination with the damper to play a role in buffering and shock absorption. This structural coordination ensures the stability and reliability of the system during operation, effectively solves the impact and vibration problems caused by changes in external forces during operation, and improves the service life and safety of the equipment.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] Embodiment 1: A clamping tool for a drilling screw forming mold comprises a workbench 1, with two pairs of fixed blocks 2 fixedly connected to the top of the workbench 1, a motor 3 is fixedly connected to the outer wall of the fixed block 2 on one side, and a bidirectional threaded rod 4 is fixedly connected to the output end of the motor 3. At the same time, the bidirectional threaded rod 4 is rotatably connected between the pair of fixed blocks 2, and the outer walls of both ends of the bidirectional threaded rod 4 are threadedly connected with a clamping plate 5, and a positioning rod 6 is fixedly connected between the fixed blocks 2 on the other side, and the other end of the clamping plate 5 is slidably connected to the outer wall of the positioning rod 6, an inner cavity 7 is opened inside the positioning rod 6, and at the same time, fixed columns 8 are fixedly connected inside the positioning rods 6 on both sides, and a pair of sliding blocks 10 are slidably connected to the outer wall of the fixed column 8, and a roller 11 is rotatably connected inside the other end of the sliding block 10, and the sliding block 10 is of a special shape, and the roller 11 is rotatably connected to the inside of one side of the inclined surface, and springs 9 are arranged at both ends of the fixed column 8, and at the same time, one end of the spring 9 is fixedly connected to the inner cavity 7, and the other end of the spring 9 is fixedly connected to the outer wall of the sliding block 10, and the spring 9 is slidably connected to the outside of the fixed column 8.

[0026] Under the action of the motor 3, the rotation of the bidirectional threaded rod 4 drives the reverse movement of the clamping plates 5 on both sides. At the same time, the movement direction of the clamping plates 5 is kept stable through the limit of the positioning rod 6. Inside the clamping plates 5, the movement of the sliding block 10 is controlled by the clamping plates 5, and the movement of the roller 11 reduces the friction with the mold and reduces damage. For large molds, the sliding blocks 10 on both sides will be pushed to move to both sides, and the spring 9 will be squeezed at the same time, so that the sliding blocks 10 are firmly stuck on the mold. This design ensures the stable clamping of the mold and realizes the rapid replacement of the mold through simple operation, thereby improving production efficiency and work efficiency.

[0027] Embodiment 2: The difference between this embodiment and embodiment 1 lies in that, a slide groove 16 is provided on the top of the two side clamps 5, and the slide groove 16 corresponds to the inner cavity 7, and a connecting block 14 is fixedly connected to the top of the sliding blocks 10 on both sides, and the connecting block 14 corresponds to the slide groove 16, and the connecting block 14 is slidably connected in the slide groove 16, and a pair of top blocks 12 are fixedly connected to the two sides of the top of the clamps 5, and a damper 13 is fixedly connected to the inner wall of the top block 12, and the end of the damper 13 is fixedly connected to the connecting block 14, and a spring 2 15 is fixedly connected between the two side connecting blocks 14, a groove is provided in the middle of the workbench 1, and a baffle 17 is provided in the groove, and a plurality of holes are provided on the baffle 17, and a refrigeration box 18 is provided at the bottom of the workbench 1, and the refrigeration box 18 corresponds to the baffle 17.

[0028] During the clamping process, the movement of the sliding block 10 causes the connecting block 14 to move in the slide groove 16, while squeezing the dampers 13 on the top blocks 12 on both sides, slowing down the movement of the connecting block 14. The damper 13 not only slows down the movement of the connecting block 14, but also pulls the spring 2 15 when the connecting block 14 moves, and cooperates with the elastic force of the spring 2 15 to buffer the clamping force of the sliding block 10, thereby protecting the mold and improving the product quality. After the casting is completed, the cold air is released through the refrigeration box 18 at the bottom of the workbench 1, and the mold is cooled through the holes on the baffle 17, so that rapid demoulding is achieved and production efficiency is accelerated.

[0029] When working, first place the mold in the middle of the two side clamps 5, and start the motor 3. Under the action of the motor 3, the bidirectional threaded rod 4 is driven to rotate. When the bidirectional threaded rod 4 rotates, the clamps 5 at both ends will be driven to move in the opposite direction. At the same time, the clamps 5 are limited by the positioning rods 6 when moving, so that the clamps 5 always keep the same direction when moving. When the clamps 5 move inward, they will drive a pair of sliding blocks 10 inside themselves to move. According to the size of the mold, they will first contact the rollers 11 on the sliding blocks 10, and the friction will be reduced by the rollers 11 to reduce damage. When the mold is large, the sliding blocks 10 on both sides will be pushed to move to both sides. At the same time, the rollers 11 will squeeze the springs 9 at both ends when moving. At this time, the resilience of the springs 9 will firmly clamp the sliding blocks 10 on the mold, and then clamp them through the clamps 5 on both sides, making the mold more stable. Through their cooperation, the mold can be realized. The invention can achieve the effect of clamping and fixing different molds, and also facilitate the replacement of molds and improve work efficiency. While fixing the mold, the sliding block 10 will drive the connecting block 14 on itself to move in the slide groove 16 during the clamping process. When the connecting block 14 moves to both sides, it will squeeze the dampers 13 on the top blocks 12 on both sides, and the movement of the connecting block 14 will be slowed down by the damping force of the damper 13. When the connecting block 14 moves, it will not only squeeze the damper 13, but also pull the spring 2 15, and cooperate with the elastic force of the spring 2 15 to buffer the supporting force of the sliding block 10. Through their cooperation, the effect of protecting the mold is achieved, the product quality is improved, and the work efficiency is accelerated. After the casting is completed, the cold air is released through the refrigeration box 18 at the bottom of the workbench 1, and the mold is cooled through the holes on the baffle 17, thereby achieving the effect of rapid demoulding.
