During the production process of mechanical workpieces, the workpieces need to be tested for compression resistance. Compression resistance testing is the process of determining its endurance and stability when subjected to pressure loads. It is an important testing step after the production of mechanical workpieces is completed, so as to ensure that the quality of the workpiece material can meet production needs.

[0024] When in use, the second electric telescopic rod 11 is used to push the slide plate 19 to slide in the first slide groove 14, and the movement of the slide plate 19 drives the connected clamping plate 20 to move, and at the same time drives the telescopic sleeve 13 to follow the movement, so that the mechanical workpiece can be clamped and fixed on the upper surface of the lower pressure plate 12, avoiding the problem of the workpiece being easily deviated and dislodged during the downward pressing process. Two sets of springs 15 are arranged inside the telescopic sleeve 13. When the telescopic sleeve 13 is subjected to pressure, the springs 15 will be squeezed by the limit columns 16 to move the telescopic sleeve 13 downward, thereby avoiding the problem that the workpiece is small and easily causes damage to the clamping plate.

[0025] Please refer to Figure 1A sleeve 7 is provided on the outside of the support column 3, and two groups of sleeves 7 are provided. A connecting block 10 is connected to one side of the sleeve 7. The lower surface of the connecting block 10 is connected to a first electric telescopic rod 8. The lower opposite bank of the first electric telescopic rod 8 is fixedly installed on the upper surface of the base 1. The connecting block 10 is driven downward by the first electric telescopic rod 8, which can drive the sleeve 7 to slide on the surface of the support column 3.

[0030] Working principle: The utility model is a pressing device for compressive testing of workpieces used in mechanical processing. First, the mechanical workpiece to be tested is placed on the lower pressure plate 12, and then the slide plate 19 is pushed to slide in the first slide groove 14 by the second electric telescopic rod 11. The movement of the slide plate 19 drives the integrated clamping plate 20 to move, and at the same time drives the telescopic sleeve 13 to move, so that the mechanical workpiece can be clamped and fixed on the upper surface of the lower pressure plate 12, and then the connecting block 10 is driven downward by the first electric telescopic rod 8, which can drive the sleeve 7 to slide on the surface of the support column 3, and the protective cover 9 is driven downward by the movement of the sleeve 7, so that the lower pressure plate 12 can be covered on the inside, and then the upper pressure plate 4 is driven downward by the hydraulic rod 5 to pass through the through hole opened on the protective cover 9 to squeeze the mechanical workpiece for compressive testing.

[0031] When the workpiece is small and the telescopic sleeve 13 exceeds the height of the workpiece, the upper pressure plate 4 will first press on the upper end of the telescopic sleeve 13 when pressing down. By arranging two sets of springs 15 inside the telescopic sleeve 13, when the telescopic sleeve 13 is subjected to pressure, the springs 15 will be squeezed by the limit columns 16 to make the telescopic sleeve 13 move downward on the outside of the clamp 20, thereby avoiding the problem that the workpiece is small and the clamp is easily damaged.
