Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for sheet metal processing, and specifically to a sheet metal clamping and fixing fixture. Background Technology

[0002] During sheet metal processing, reliable clamping and fixing of the sheet metal is necessary to ensure processing accuracy and stability. Existing sheet metal clamping fixtures have revealed many problems in practical applications. Some fixtures use complex mechanical linkage structures or hydraulic / pneumatic systems to clamp the sheet metal. While these fixtures can meet clamping requirements to a certain extent, their complex structure and numerous parts result in high manufacturing costs, as well as high maintenance difficulty and costs. Some clamping fixtures also suffer from unstable clamping force. When the clamping force is insufficient, the sheet metal is prone to displacement or loosening during sheet metal processing, especially during high-speed cutting and heavy-duty stamping operations. This not only leads to decreased processing accuracy, dimensional deviations, and unacceptable surface roughness, but in severe cases, it can also cause workpiece scrap, resulting in waste of raw materials and processing costs. Therefore, it is necessary to design a sheet metal clamping and fixing fixture that is simple in structure, easy to operate, and has a stable and reliable clamping force. Summary of the Invention

[0003] The purpose of this utility model is to provide a plate clamping and fixing fixture to solve the related problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: including a plate support base, a limiting protrusion disposed on one side of the plate support base, and an installation groove disposed on the other side of the plate support base, wherein a set of locking devices for cooperating with the limiting protrusion to clamp the plate is provided in the installation groove; Furthermore, the locking device includes a left slider and a right slider, and a driving slider for driving the left slider and the right slider to move relative to each other is provided between the left slider and the right slider. Both sides of the driving slider are provided with active wedges, and the left slider and the right slider are provided with driven wedges adapted to the active wedges. A driving component for driving the driving slider to move downward is also provided.

[0005] To ensure the plate is clamped, the drive assembly includes a drive bolt, the drive slider is provided with a drive countersunk hole, and there is a left and right sliding gap between the drive countersunk hole and the drive bolt. The bottom of the mounting groove is provided with a set of threaded holes that are adapted to the drive bolt along the groove direction.

[0006] To achieve automatic reset, a retraction component is provided between the left and right sliders to drive the left and right sliders to move in opposite directions.

[0007] Preferably, the retraction assembly includes locking posts respectively disposed on the front and rear sides of the left and right sliders, and an annular spring sleeved between the two locking posts on the same side.

[0008] To prevent the annular spring from falling off, each of the locking posts is provided with a limiting groove that is compatible with the annular spring.

[0009] Furthermore, the annular spring is provided with an anti-detachment plate, which includes a vertical plate and hook-shaped parts symmetrically arranged at the upper and lower ends of the vertical plate and adapted to the outer diameter of the annular spring.

[0010] To facilitate fixing, the plate support is provided with a set of countersunk holes, and fixing bolts for locking the plate support onto the machine tool processing table are provided in the countersunk holes.

[0011] The beneficial effects of this utility model are as follows: Based on the principle of wedge transmission, this utility model uses a driving bolt to drive the driving slider downwards. During the clamping process, the left slider and the second left side wall of the mounting groove simultaneously push the right slider towards the plate, thus firmly clamping the plate between the right slider and the limiting protrusion. This utility model has a simple structure, is easy to operate, and has a stable and reliable clamping force, effectively preventing the plate from loosening or shifting during processing. This utility model uses only mechanical transmission, which greatly simplifies the structure compared to traditional complex hydraulic and pneumatic clamping systems, reducing the use of many parts and effectively lowering manufacturing and maintenance costs. The retraction component automatically drives the left and right sliders to retract in opposite directions after the plate is processed, allowing the right slider to quickly move away from the limiting protrusion, making room for the next plate and facilitating rapid loading, thus improving work efficiency. This process requires no additional manual intervention, greatly shortening the loading preparation time. Simultaneously, the limiting slot and anti-detachment plate work together to ensure that the ring spring will not detach from the clamping post. Attached Figure Description

[0019] like Figure 1-7 As shown, a sheet metal clamping and fixing fixture includes a sheet metal support 1, a limiting protrusion 2 located on the right side of the sheet metal support 1, and a mounting groove 11 located on the left side of the sheet metal support 1 and parallel to the limiting protrusion 2. A set of locking devices 3 are provided in the mounting groove 11 for cooperating with the limiting protrusion 2 to clamp the sheet metal. The width from the first left side wall 21 of the limiting protrusion 2 to the second right side wall 111 of the mounting groove 11 is shorter than the width of the sheet metal. The locking devices 3 push the sheet metal to the right, thereby cooperating with the limiting protrusion 2 to firmly clamp the sheet metal.

[0020] To achieve clamping, the locking device 3 includes a left slider 31 and a right slider 32 disposed in the mounting groove 11. A driving slider 33 is disposed between the left slider 31 and the right slider 32 to drive the left slider 31 and the right slider 32 to move relative to each other. The upper ends of the left slider 31 and the right slider 32 are higher than the upper end surface of the plate support 1, so as to cooperate with the limiting protrusion 2 to achieve clamping. Both sides of the driving slider 33 are provided with active wedges 331, and both the left slider 31 and the right slider 32 are provided with driven wedges 37 adapted to the active wedges 331. A driving assembly 34 is also provided to drive the driving slider 33 to move downward. The drive assembly 34 includes a drive bolt 341. The drive slider 33 is provided with a drive countersunk hole 332, and a left and right sliding gap 35 is left between the drive countersunk hole 332 and the drive bolt 341. The bottom of the mounting groove 11 is provided with a set of threaded holes 12 that are adapted to the drive bolt 341 along the groove direction. The number of locking devices 3 can be selected according to the length of the plate. By turning the drive bolt 341 downwards, the drive slider 33 moves downwards, and then the active wedges 331 on both sides push the driven wedges 37 on the left slider 31 and the right slider 32 respectively, thereby pushing the left slider 31 and the right slider 32 to move in opposite directions. When the left slider 31 slides to the left and abuts against the second left side wall 112 of the mounting groove 11 and can no longer slide, the drive bolt 341 is turned downwards again. The left slider 31 abuts against the second left side wall 112 and remains stationary. The left slider 31 and the second left side wall 112 cooperate to provide a rightward thrust, so that the drive slider 33 moves downwards to squeeze the left slider 31 and the right slider 32, and slides to the right together with the right slider 32 to push the plate, thereby cooperating with the limiting protrusion 2 to firmly clamp the plate.

[0021] To facilitate material loading, a retraction assembly 36 is provided between the left slider 31 and the right slider 32 to drive them to move towards each other. The retraction assembly 36 includes locking posts 361 respectively located on the front and rear sides of the left slider 31 and the right slider 32, and an annular spring 362 sleeved between the two locking posts 361 on the same side. When the sheet material is processed, the drive bolt 341 is loosened. The two annular springs 362 contract, causing the left slider 31 and the right slider 32 to move towards each other and retract. This causes the right slider 32 to move to the left, away from the limiting protrusion 2, thus facilitating the placement of the next sheet material on the support base 1, achieving rapid material loading and improving work efficiency. The annular structure of the annular spring 362 ensures uniform deformation during contraction, stably driving the left slider 31 and the right slider 32 to move synchronously towards each other. Each locking post 361 is provided with a limiting groove 3611 adapted to the annular spring 362. The annular spring 362 is provided with an anti-detachment locking plate 363, which includes a vertical plate 3631 and hook-shaped portions 3632 symmetrically arranged at the upper and lower ends of the vertical plate 3631 and adapted to the outer diameter of the annular spring 362. The limiting groove 3611 locks the annular spring 362 to prevent it from slipping, while the anti-detachment locking plate 363 hooks the upper and lower ends of the annular spring 362 between the two locking posts 361, preventing the annular spring 362 from popping out of the limiting groove 3611 when it retracts, thus ensuring that the annular spring 362 cannot detach from the locking post 361.

[0022] To facilitate fixing this utility model on a machine tool processing table, a set of countersunk holes 13 are provided on the plate support 1, and fixing bolts 131 for locking the plate support 1 on the machine tool processing table are provided in the countersunk holes 13.

[0023] The working principle of this utility model is as follows: First, place the left end of the plate with the right end attached to the limiting protrusion 2 on the plate support seat 1. Then, turn the drive bolt 341 downward to drive the right slider 32 to firmly clamp the plate. After the plate is processed, loosen the drive bolt 341 and take out the plate. The left slider 31 and the right slider 32 move towards each other and retract under the action of the retraction component 36. Then, put in the next plate for processing.
