The following is a brief description of the content expressed in the drawings of this manual and the marks in the drawings:

Fig. 1 is the structural representation of the utility model.

Marked among the figure are: 1, workbench, 2, workpiece, 3, pressure plate, 4, support pad, 5, screw rod, 6, adjusting nut, 7, gap.

Detailed ways

The specific implementation of the present utility model will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

The workpiece clamping device of the utility model, as shown in Fig. 1, is used for clamping the workpiece on the workbench 1, and is a clamping device with simple structure and flexible and convenient use. The device includes a pressing plate 3, a screw 5 and a spacer 4. The workbench 1 using this device is made up of a plurality of work boards, and a gap 7 is provided between each work board, and the size of the gap 7 can be passed by the screw rod 5 . After determining the position of the workpiece 2 to be processed, pass the screw 5 at the appropriate corresponding position, connect the lower end of the screw 5 to the stopper, and use the stopper to clamp the screw 5 on the bottom surface of the workbench to prevent the screw 5 from going up and down. move. The pressing plate 3 is sleeved on the screw rod 5 located on the upper part of the workbench 1 to compress the workpiece 2 . Above the pressure plate 3, the upper end of the screw rod 5 is provided with an adjustment nut 6 that limits the position of the pressure plate 3; according to the thickness of the workpiece 2, the position of the pressure plate 3 is adjusted, and one end of the pressure plate 3 is pressed on the workpiece 2, and the other end is provided with a supporting pad 4 , to pad the other end of the pressing plate 3, so that the pressing plate 3 has a better pressing force on the workpiece 2.

The supporting cushion block 4 in the utility model is a stepped structure, which can be applied to workpieces of different thicknesses. The support pad 4 is provided with multi-stage steps, and also can be provided with a plurality of stepped support pads 4 of different grades and heights according to actual usage conditions, which is convenient for use.

The hole set on the screw rod 5 on the pressure plate 3 can be a through hole or a threaded hole, preferably a threaded hole, which is threaded with the threaded hole on the screw rod 5. The use of the threaded hole can make the clamping effect on the workpiece more stable and ensure accurate processing.

In the utility model, the pressing plate 3 has a strip structure, which is convenient for processing and manufacturing, and the strip is similar to a lever structure, which is convenient for clamping. The threaded hole is located in the middle of the pressing plate 3, which is convenient for coordinating the effects of both ends, and placing the workpiece and the supporting pad 4.

The workpiece clamping device of the utility model has the advantages of simple structure, convenient manufacture and use, and low cost. The position can be moved on the same workbench, and it is suitable for clamping workpieces of different sizes, and the clamping is flexible; On different workbenches, it has good versatility and reduces hidden costs; with the use of stepped support pads 4, it can be used to clamp workpieces of different thicknesses, reduce the number of pads, reduce space occupation, easy to store and use, and has a strong practicality.

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned method, as long as various insubstantial improvements or direct improvements are made by adopting the method concept and technical solutions of the utility model. Those applied to other occasions are all within the protection scope of the present utility model.
