Abstract
Description
Technical Field
[0001] This utility model relates to the field of workpiece fixing technology, and in particular to a mechanism for clamping from both sides simultaneously. Background Technology
[0002] When welding automotive parts, clamping mechanisms are needed to fix the parts to facilitate subsequent welding operations. However, current clamping mechanisms cannot fix both sides of the automotive parts simultaneously, which affects work efficiency. Therefore, it is necessary to design a clamping mechanism that can clamp both sides at the same time. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mechanism that clamps both sides simultaneously.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a clamping mechanism on both sides, including a mounting base, a cylinder fixedly connected to the lower end of the mounting base, connecting seats fixedly connected to both protruding ends of the cylinder, a clamping arm rotatably connected inside the connecting seat, connecting plates fixedly connected to both the front and rear sides of the clamping arm, a fixing pin penetrating through the connecting plate, and the fixing pin rotatably connected to the mounting base; a clamping block fixedly connected to the end of the clamping arm away from the connecting seat; a support block fixedly connected to the upper end of the mounting base, the support block corresponding to the clamping block.
[0005] As a further description of the above technical solution:
[0006] The lower end of the cylinder is fixedly connected to an air passage connector, and there are two air passage connectors.
[0007] As a further description of the above technical solution:
[0008] A stop block is fixedly connected to the front side of the connecting plate, and a nut is threaded onto the circumferential surface of the fixing pin.
[0009] As a further description of the above technical solution:
[0010] Positioning baffles are fixedly connected to the front ends of the clamping arms located on the left and the right.
[0011] As a further description of the above technical solution:
[0012] The clamping block is L-shaped, and the end of the clamping block near the support block is made of rubber material.
[0013] As a further description of the above technical solution:
[0014] A pressure sensor is fixedly connected inside the front end of the mounting base.
[0015] This utility model has the following beneficial effects:
[0016] Compared with existing technologies, this dual-side clamping mechanism, through the arrangement of cylinders, connecting seats, clamping arms, fixing pins, and clamping blocks, allows for simultaneous clamping of automotive parts during welding. First, the part to be welded is placed on the support block. Then, the cylinder extends, and with the cooperation of the connecting seat, the two clamping arms rotate around the fixing pin, thereby moving the clamping block closer to the support block. After the clamping block contacts the part, the part is then fixed with the cooperation of the support block. Since there are two clamping arms and two clamping blocks, both sides of the part can be clamped and fixed simultaneously, thus improving the fixing efficiency of the part.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figure 1-3The present invention provides a dual-sided clamping mechanism, comprising a mounting base 1, a cylinder 2 fixedly connected to the lower end of the mounting base 1, and connecting seats 3 fixedly connected to both protruding ends of the cylinder 2. A clamping arm 4 is rotatably connected inside the connecting seat 3, and connecting plates 5 are fixedly connected to both the front and rear sides of the clamping arm 4. A fixing pin 6 passes through the connecting plate 5 and is rotatably connected to the mounting base 1. In use, the fixing pin 6 passes through the connecting plate 5 and the mounting base 1, thus facilitating the connection of the clamping arm 4 and the mounting base 1 with the cooperation of the connecting plate 5. A clamping block 7 is fixedly connected to the end of the clamping arm 4 away from the connecting seat 3; a support block 8 is fixedly connected to the upper end of the mounting base 1, corresponding to the clamping block 7.
[0024] In use, the parts to be welded are placed on the support block 8, and then the cylinder 2 extends. With the cooperation of the connecting seat 3, the two clamping arms rotate around the fixing pin 6, thereby driving the clamping block 7 to move closer to the support block 8. After the clamping block 7 contacts the parts, the parts can be fixed with the cooperation of the support block 8. Since there are two clamping arms 4 and two clamping blocks 7, the parts can be clamped and fixed on both sides at the same time, thereby improving the fixing efficiency of the parts. Conversely, when the cylinder 2 retracts, the two clamping arms 4 open, which moves the clamping block 7 away from the workpiece, thereby releasing the fixation of the workpiece.
[0025] The lower end of cylinder 2 is fixedly connected to an air passage connector 12. There are two air passage connectors 12. During operation, by setting the air passage connectors 12, it is convenient to connect to an external air source.
[0026] A stop block 11 is fixedly connected to the front side of the connecting plate 5, and a nut is threaded onto the circumferential surface of the fixing pin 6. During operation, after the fixing pin 6 passes through the mounting base 1 and the connecting plate 5, the nut is tightened. With the cooperation of the stop block 11, the fixing pin 6 can be blocked, thus facilitating the tightening of the nut.
[0027] Positioning baffles 9 are fixedly connected to the front ends of the clamping arm 4 on the left and the clamping arm 4 on the right. During operation, by setting the positioning baffles 9, the clamping block 7 can be limited, which is conducive to the clamping block 7 corresponding to the support block 8.
[0028] The clamping block 7 is L-shaped, and the end of the clamping block 7 near the support block 8 is made of rubber. During operation, the L-shaped clamping block 7 makes it easy to install on the clamping arm 4. At the same time, the rubber material at the end of the clamping block 7 near the support block 8 reduces damage to the parts when clamping them.
[0029] A pressure sensor 10 is fixedly connected inside the front end of the mounting base 1. During operation, by setting the pressure sensor 10, the placement of the parts can be sensed under the action of the pressure sensor 10, which is beneficial for subsequent clamping operations.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
