It is also called a clamp. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process in the process can be called a fixture.

[0003] The existing plate clamp design has certain limitations in terms of operational flexibility and work efficiency. Traditional clamps mostly adopt a one-sided fixed and one-sided movable mode. When dealing with plates of different sizes, this design requires a larger moving stroke to achieve precise clamping, which results in a longer clamping process and affects the overall efficiency of the production process. Utility Model Content

[0004] The technical problem to be solved by the utility model is that in the prior art, when clamping plates of different specifications, a large moving stroke is required to achieve precise clamping, which leads to a long clamping process. For this reason, we propose a quick plate clamp.

[0006] Preferably, a connecting disk is installed at one end of the screw rod away from the clamping block, and a handle is installed on one side of the connecting disk.

[0007] Preferably, a groove is provided on the surface of the round block, and a plurality of balls are installed inside the groove, and the balls cooperate with the inner diameter of the round groove.

[0008] Preferably, both sides of the guide rail are provided with slide grooves, and a sliding block is installed on the side of the clamping block close to the guide rail, and the sliding block is slidably connected to the inside of the slide groove.

[0009] Preferably, a through groove is provided at the top of the sliding block, a plurality of rotating shafts are installed inside the through groove, auxiliary wheels are rotatably connected to the surfaces of the rotating shafts, and guide grooves for use with the auxiliary wheels are provided at the top and bottom of the sliding groove.

[0010] Preferably, a first gasket is installed on a side of the limiting block close to the clamping block.

[0011] Preferably, a second gasket is installed on one side of the clamping block close to the limiting block.

[0012] Technical effects and advantages of the utility model:

[0013] In the utility model, by using the clamping block and the limit block in coordination, after the plate is placed on the top of the guide rail, it is first preliminarily positioned by the limit block, so that the plate is as close to the base plate as possible, thereby reducing the travel required for the clamping block to move, so that the clamping block can contact the plate more quickly when clamping the plate, accelerating the clamping process and improving the efficiency of the clamping operation.

[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1-Figure 5As shown, the utility model provides a technical solution: a sheet material quick clamp, including a guide rail 1, a plurality of jacks 2 are provided on the top of the guide rail 1, a limiting column 3 is inserted inside the jack 2, a limiting block 4 is inserted on the top of the limiting column 3, a base plate 5 is installed at one end of the guide rail 1, a screw rod 6 is connected to the inner thread of the base plate 5, a clamping block 7 is installed at one end of the screw rod 6, a round block 10 is installed at the end of the screw rod 6 close to the clamping block 7, a round groove 11 used in conjunction with the round block 10 is provided inside the clamping block 7, a connecting plate 8 is installed at the end of the screw rod 6 away from the clamping block 7, a handle 9 is installed on one side of the connecting plate 8, a sheet material is placed on the top of the guide rail 1, and after the position is determined, the plate material is clamped by the limiting column 3 and the jack. 2 is inserted to initially limit the plate, and then the plate is abutted by inserting the limit block 4 with the limit column 3, and then the rotation of the screw 6 is controlled by the handle 9 and the connecting plate 8, and the sliding connection between the round block 10 and the round groove 11 is used to prevent the clamping block 7 from rotating when the screw 6 rotates, and at the same time, the clamping block 7 clamps the plate. Through the coordinated use of the clamping block 7 and the limit block 4, after the plate is placed on the top of the guide rail 1, it is first initially positioned by the limit block 4, so that the plate is as close to the substrate 5 as possible, thereby reducing the travel required for the clamping block 7 to move, so that the clamping block 7 can contact the plate more quickly when clamping the plate, accelerate the clamping process, and improve the efficiency of the clamping operation.

[0023] Reference Figure 4 As shown, in this embodiment: a groove 12 is provided on the surface of the round block 10, and a plurality of balls 13 are installed inside the groove 12. The balls 13 are used in conjunction with the inner diameter of the circular groove 11. By providing the groove 12 and installing the balls 13, the balls 13 are in contact with the inner wall of the circular groove 11 when the round block 10 rotates, reducing the contact area between the round block 10 and the circular groove 11, thereby reducing the friction force when the screw 6 rotates, making it more convenient for users to use and speeding up the clamping speed.

[0024] Reference Figure 6 As shown, in this embodiment: slide grooves 15 are provided on both sides of the guide rail 1, and a slider 14 is installed on the side of the clamping block 7 close to the guide rail 1. The slider 14 is slidably connected to the inside of the slide groove 15. Through the sliding connection between the slider 14 and the slide groove 15, the moving trajectory of the clamping block 7 is limited to prevent the clamping block 7 from tilting when moving.

[0025] Reference Figure 6 As shown, in this embodiment: a through groove 16 is provided on the top of the slider 14, a plurality of rotating shafts 17 are installed inside the through groove 16, and an auxiliary wheel 18 is rotatably connected to the surface of the rotating shaft 17. Guide grooves 19 used in conjunction with the auxiliary wheels 18 are provided on the top and bottom of the slide groove 15. By installing the auxiliary wheels 18 and using the guide grooves 19 in conjunction with each other, the resistance of the slider 14 when sliding inside the slide groove 15 is reduced, so as to facilitate the movement of the clamping block 7.

[0026] Reference Figure 1 and Figure 3 As shown, in this embodiment: a first gasket 20 is installed on the side of the limit block 4 close to the clamping block 7, and a second gasket 21 is installed on the side of the clamping block 7 close to the limit block 4. The setting of the first gasket 20 and the second gasket 21 can protect the plate during clamping. The first gasket 20 and the second gasket 21 are both made of rubber material, which can effectively prevent the wear of the plate.

[0027] Working principle: the user places the plate on the top of the guide rail 1, and after determining the position, the plate is initially limited by plugging the limit column 3 with the socket 2, and then the plate is abutted by plugging the limit block 4 with the limit column 3, and then the rotation of the screw 6 is controlled by the handle 9 and the connecting plate 8. The sliding connection between the round block 10 and the round groove 11 prevents the clamping block 7 from rotating when the screw 6 rotates, and at the same time enables the clamping block 7 to clamp the plate. The sliding connection between the slider 14 and the slide groove 15 limits the moving trajectory of the clamping block 7 to prevent the clamping block 7 from tilting when moving. The installation of the auxiliary wheel 18 and the coordinated use of the guide groove 19 make the slider 14 in the slide groove 15 The resistance when the parts slide is reduced to facilitate the movement of the clamping block 7. By opening the groove 12 and installing the ball 13, the ball 13 contacts the inner wall of the circular groove 11 when the round block 10 rotates, reducing the contact area between the round block 10 and the circular groove 11, thereby reducing the friction when the screw 6 rotates, making it more convenient for users to use and speeding up the clamping speed. Through the coordinated use of the clamping block 7 and the limit block 4, after the plate is placed on the top of the guide rail 1, it is first initially positioned by the limit block 4, so that the plate is as close to the substrate 5 as possible, thereby reducing the travel required for the clamping block 7 to move, so that the clamping block 7 can contact the plate more quickly when clamping the plate, speeding up the clamping process and improving the efficiency of the clamping operation.
