[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0043] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.
[0044] The following is combined with Figure 1-4 The present application is further described.
[0045] Reference Figure 1-Figure 3 , is a clamping device provided in the present application, which includes a workbench 1, and the workbench 1 has a bearing surface 11 for bearing a workpiece. A first bracket 2, a first clamping mechanism 3, a second bracket 4 and a second clamping mechanism 5 are arranged on the bearing surface 11 of the workbench 1. Among them, the first bracket 2 is fixedly arranged on the workbench 1, and the first clamping mechanism 3 is arranged on the first bracket 2. The first clamping mechanism 3 includes a bidirectional screw 31 rotatably arranged on the first bracket 2 and parallel to the bearing surface 11, a first nut 32 respectively threadedly engaged with the outer side of the threads of the bidirectional screw 31 with different rotation directions, a first clamping member 33 respectively arranged on the first nut 32, and a first limit assembly 34 for limiting the first nut 32 to move in a straight line. The second bracket 4 is arranged on the first bracket 2; the second clamping mechanism 5 includes a second screw rod 51 rotatably arranged on the second bracket 4 and perpendicular to the bearing surface 11, a second nut 52 rotatably arranged on the second screw rod 51 at one end facing the bearing surface 11, a second clamping member 53 arranged on the second nut 52, and a second limiting assembly 54 for limiting the second nut 52 to move in a straight line.
[0046] The above settings ensure that the first clamping mechanism 3 and the second clamping mechanism 5 are used to fix the workpiece during workpiece processing. The first clamping mechanism 3 and the second clamping mechanism 5 fix the workpiece in directions parallel to the load-bearing surface 11 and perpendicular to the load-bearing surface 11, respectively, so that the workpiece has fixing forces in at least two directions during the processing, thereby achieving a stable and reliable fixing effect on the workpiece, and the fixing forces in two mutually perpendicular directions can adapt to the processing of workpieces of different shapes and sizes, thereby improving the adaptability of the clamping device.
[0047] A support leg 61 is fixedly provided at the bottom of the workbench 1 to provide stable support. A rubber seat 62 is provided at the bottom of the support leg 61. The rubber seat 62 is in direct contact with the ground to improve the anti-slip ability.
[0048] Reference Figure 2The first bracket 2 includes a first fixed block 21 fixedly arranged on the bearing surface 11, the first fixed block 21 is in an elongated shape and its length direction is parallel to the axial direction of the bidirectional screw 31, the first limiting assembly 34 includes a first limiting groove 341 opened on the first fixed block 21 along the axial direction of the bidirectional screw 31, the bidirectional screw 31 is rotatably arranged in the first limiting groove 341, and the first nut 32 is slidably arranged in the first limiting groove 341. More specifically, the first limiting groove 341 is located on the inner wall of both ends of the bidirectional screw 31, and the first bearings 35 are fixedly embedded therein, and the two ends of the bidirectional screw 31 are respectively fixedly inserted into the inner rings of the two first bearings 35 to realize the function of the bidirectional screw 31 being rotatably arranged in the first limiting groove 341 through the first bearing 35. The first nut 32 refers to a structure threadedly fitted on the outside of the bidirectional screw 31, which can also be called a threaded sleeve. When the bidirectional screw 31 is rotated, the first nut 32 can only move along the axial direction of the bidirectional screw 31 due to the limiting effect of the first limiting groove 341, thereby driving the two first clamping members 33 to move closer to or away from each other, so as to fix the workpiece along the axial direction of the bidirectional screw 31.
[0049] In an optional embodiment, one end of the bidirectional screw rod 31 passes through the first fixed block and forms a first end 311, and a first knob 312 is fixed to the first end 311. A first rubber layer is provided on the first knob 312 to facilitate the operator to turn it. In other optional embodiments, anti-slip grooves may also be designed on the first rubber layer.
[0050] Reference Figure 2 and Figure 3 In an optional embodiment, the first clamping member 33 is plate-shaped. In an optional embodiment, the first clamping member 33 has a first side surface 331 facing the fixed block, and the first side surface 331 abuts against the first fixed block 21. The first clamping member 33 has a first end surface 311 facing the bearing surface 11, and the first end surface 311 abuts against the bearing surface 11. This setting ensures the accuracy of the first clamping member 33 during movement to ensure stable and reliable clamping of the workpiece, especially when clamping a plate-shaped workpiece, because the two side surfaces of the workpiece are generally parallel to the facing surfaces of the two first clamping members 33 when placing the plate-shaped workpiece, the setting of ensuring that the first side surface 331 abuts against the first fixed block 21 and the first end surface 311 abuts against the bearing surface 11 can ensure that the first clamping member 33 moves strictly along the axial direction of the bidirectional screw 31, reduce displacement errors, and improve the stability of the workpiece when it is fixed.
[0051] In one of the optional embodiments, the dimension of the first side surface 331 along the axial direction of the second screw rod 51 is greater than or equal to the dimension of the first fixing block 21 along the axial direction of the second screw rod 51. This ensures that the first side surface 331 is in full contact with the first fixing block 21 to increase the contact limiting area, thereby improving the stability of the movement of the first clamping member 33.
[0052] Reference Figure 2 and Figure 3 At least two second clamping mechanisms 5 are provided, and the second clamping mechanisms 5 are spaced apart along the axial direction of the bidirectional screw rod 31. When welding is required, the two second clamping mechanisms 5 can fix different workpieces respectively to meet more diverse usage requirements and improve applicability.
[0053] Reference Figure 2 and Figure 3 The second bracket 4 includes a second fixed block 41 disposed on the side of the first bracket 2 away from the bearing surface 11 and an extension platform 42 fixedly disposed on the second fixed block 41 and parallel to the bearing surface 11. The second clamping mechanism 5 includes a second screw rod 51 threadedly penetrating the extension platform 42 and disposed perpendicular to the bearing surface 11, a second nut 52 rotatably disposed at one end of the second screw rod 51 facing the bearing surface 11, a second clamping member 53 disposed on the second nut 52, and a second limit assembly 54 for limiting the second nut 52 from moving in a straight line. More specifically, a second bearing 55 is fixedly disposed on the second clamping member 53, and the end of the second screw rod 51 is plugged and fixed to the inner ring of the second bearing 55.
[0054] Reference Figure 3 and Figure 4 The second limiting assembly 54 includes a second limiting groove 541 provided on the second fixing block 41 along the axial direction of the second screw rod 51, and a second limiting block 542 is provided on the second nut 52, and the second limiting block 542 is slidably disposed in the second limiting groove 541. The second clamping member 53 is bolted to the second nut 52. A second knob 511 is provided at one end of the second screw rod 51 away from the second nut 52, and a second rubber layer is provided on the outside of the second knob 511.
[0055] When the second screw rod 51 is rotated, the threaded cooperation between the second screw rod 51 and the extension platform 42 drives the second nut 52 to rise or fall. The second nut 52 can only move in a direction perpendicular to the bearing surface 11 under the limiting action of the second limit block 542, thereby driving the second clamping member 53 to rise or fall, thereby completing the limiting of the workpiece in the direction perpendicular to the bearing surface 11.
[0056] The above description is only a partial implementation method of the embodiments of the present application and does not constitute any form of limitation on the application. The protection scope of the embodiments of the present application is not limited thereto. Any simple modifications, equivalent changes and modifications that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the embodiments of the present application should be covered within the protection scope of the embodiments of the present application.
