Description

Work clamping fixture

technical field

The utility model relates to the technical field of clamping mechanisms, in particular to a workpiece clamping and fixing device.

Background technique

In the production process, it is usually necessary to use a clamping mechanism to clamp the workpiece or product to facilitate the assembly or transportation of the workpiece or product. Most of the current clamping mechanisms have a briquetting block and a base, and the distance between the briquetting block and the base is usually adjusted by screw driving, so as to realize the clamping of workpieces or products between the briquetting block and the base. However, this kind of clamping mechanism needs to rotate the screw rod when clamping the workpiece or product, which makes its clamping operation complicated, and its work efficiency will be greatly reduced when performing frequent clamping and loosening operations.

Utility model content

The main purpose of the utility model is to provide a workpiece clamping and fixing device for the above problems, which has a simple structure and is convenient for clamping workpieces.

In order to achieve the above object, the utility model adopts the following technical solutions: a workpiece clamping and fixing device, which is characterized in that it includes a base, a cylinder, a gear box, and a left clamping arm and a right clamping arm; the gear box is fixed on On the base, there are openings on both sides of the gear box for the extension of the left clamping arm and the right clamping arm, the top of the gear box is provided with a workpiece placement platform, and the left clamping arm and the right clamping arm One end of the tight arm is respectively installed in the inside of the gear box through the rotating shaft, and the gears meshing with each other are respectively fixed on the two rotating shafts, one of the rotating shafts extends outwards and is connected with one end of the connecting rod, and the other end of the connecting rod It is connected with the piston rod of the cylinder, and the cylinder is fixed on the base; the ends of the left clamping arm and the right clamping arm are respectively fixed with connection plates, and the connection plates are connected with adjustment blocks by bolts, and the adjustment The ends of the blocks are bolted with spacers. Compared with the prior art, this device drives the left and right clamping arms to clamp and fix the workpiece through the cylinder and the intermeshing gears. The structure is simple, and the workpiece can be loaded and unloaded quickly and stably, which improves the work efficiency and reduces labor strength.

Preferably, the upper part of the workpiece placement platform is fixed with a limit mechanism, and there are two limit mechanisms. The limit mechanism includes a limit bolt and a support block, and the limit bolt is fixed on the workpiece placement platform through a support block. One end of the limit bolt cooperates with the inner side of the left clamping arm and the right clamping arm.

The beneficial effects of the utility model are: compared with the prior art, the device drives the left and right clamping arms to clamp and fix the workpiece through the cylinder and the gears meshing with each other. The structure is simple, and the workpiece can be loaded and unloaded quickly and stably. Improve work efficiency and reduce labor intensity.

Detailed ways

The specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. As shown in Figures 1 and 2, a workpiece clamping and fixing device includes a base 1, a cylinder 2, a gear box 3, a left clamping arm 4, and a right clamping arm 5; the gear box is fixed on the base , there are openings on both sides of the gear box for the extension of the left clamping arm and the right clamping arm, and the top of the gear box is provided with a workpiece placement platform 6, so that the left clamping arm and the right clamping arm can go up After swinging, the upper workpiece is clamped, and one end of the left clamping arm and the right clamping arm are installed in the inside of the gear box through the rotating shaft respectively, and mutually meshing gears 7 are respectively fixed on the two rotating shafts, one of which rotates The axial extension is connected with one end of the connecting rod 8, and the other end of the connecting rod is connected with the piston rod of the air cylinder, and the air cylinder is fixed on the base. The ends of the left clamping arm and the right clamping arm are respectively fixed with connecting plates 9 , the connecting plates are connected with adjusting blocks 10 through bolts, and the ends of the adjusting blocks are connected with pads 11 through bolts.

Further, in order to prevent the left clamping arm and the right clamping arm from swinging too much, the upper part of the workpiece placement platform is fixed with a limit mechanism. There are two limit mechanisms, and the limit mechanism includes a limit bolt 12 and a support block 13. The limit bolt is fixed on the workpiece placement platform through a support block, and one end of the limit bolt cooperates with the inner side of the left clamping arm and the right clamping arm.

Working principle: When in use, place the device on the processing table, the cylinder is in the retracted state, the left clamping arm and the right clamping arm are in the open state, place the workpiece on the workpiece placement platform, start the cylinder, and the cylinder Drive the connecting rod to move to the right, the connecting rod drives the rotating shaft to rotate, and the two gears rotate relative to each other, so that the left clamping arm and the right clamping arm clamp the workpiece placed on the platform, and finally process the fixed workpiece. The device drives the left and right clamping arms to clamp and fix the workpiece through the cylinder and the gears meshing with each other. The structure is simple, and the workpiece can be loaded and unloaded quickly and stably, which improves the work efficiency and reduces the labor intensity.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
