[0008] Preferably, buffer pads are evenly installed on the top of the base, and the buffer pads are evenly distributed in a cross shape on the base, and the cross-section of the buffer pads is circular.

[0009] Preferably, anti-skid bumps are evenly installed on opposite sides of the clamping plate, and the cross-section of the anti-skid bumps is trapezoidal, and the anti-skid bumps are distributed at equal intervals on the clamping plate.

[0010] Preferably, the auxiliary clamping mechanism includes a limiting guide groove opened at the top of the base, and a roller is installed inside the limiting guide groove, the top of the roller extends to the outside of the base, and a clamping block is installed at the top of the roller, and one side of the clamping block is connected to one side of the guide block.

[0011] Preferably, four limiting guide grooves are provided, and the limiting guide grooves are distributed in an X shape on the base, and the width of the clamping block is matched with the inner width of the clamping plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the shock-absorbing clamping mechanism for the electric hydraulic hammer not only realizes multi-directional clamping of the workpiece, but is also suitable for workpieces of different sizes;

[0014] (1) Through the telescopic effect of the electric telescopic rod, the two clamping plates are brought closer to each other, so as to achieve the left and right clamping effect on the workpiece, and with the cooperation of the limit guide groove, the clamping block, etc., the other two sides of the workpiece are further clamped, so as to increase the clamping contact area of ​​the workpiece, so as to further ensure the stability of the workpiece during the forging process. At the same time, this clamping method can adapt to workpieces of different sizes, and utilize the effect of the ball to increase the contact friction between the clamping plate and the workpiece, so as to improve the clamping stability. At the same time, since the movement of the clamping block does not require the cooperation of additional electrical equipment, the use cost of the structure is reduced;

[0026] Specifically, Figure 1 , Figure 2 As shown, when in use, the cushion pad 10 is deformed to absorb the hammer pressure, thereby reducing the rigid impact between the workpiece and the base 1 to avoid damage to the bottom end of the workpiece;

[0027] The top of the base 1 is equipped with an electric hydraulic hammer body 2, and fixing plates 3 are installed on both sides of the top of the base 1 below the electric hydraulic hammer body 2, and electric telescopic rods 6 are installed on the inner sides of the fixing plates 3, and a clamping plate 4 is installed on one side of the electric telescopic rod 6;

[0028] The opposite sides of the clamping plate 4 are evenly installed with anti-skid protrusions 11, and the cross-section of the anti-skid protrusions 11 is trapezoidal, and the anti-skid protrusions 11 are evenly spaced on the clamping plate 4;

[0029] Specifically, Figure 2 , Figure 4 As shown, when in use, the anti-slip protrusion 11 acts to further increase the contact friction between the workpiece and the clamping plate 4, thereby improving the clamping stability of the workpiece;

[0030] Guide rods 7 are installed at both ends of the clamping plate 4 close to the fixed plate 3, and one end of the guide rod 7 penetrates the outside of the fixed plate 3, and guide grooves 9 are evenly opened at both ends of the inside of the clamping plate 4;

[0031] There are two groups of guide grooves 9, and each group has four guide grooves. The guide grooves 9 are symmetrically distributed about the central axis of the clamping plate 4. The guide block 8 forms a left-right sliding structure with the clamping plate 4 through the action of the guide grooves 9.

[0032] Specifically, Figure 3 , Figure 4 As shown, when in use, the guide groove 9 is used to limit the moving direction and moving distance of the guide block 8;

[0033] The guide grooves 9 are connected with guide blocks 8, and one side of the guide blocks 8 is provided with an auxiliary clamping mechanism 5;

[0034] The auxiliary clamping mechanism 5 includes a limiting guide groove 501 provided at the top of the base 1, and a roller 503 is installed inside the limiting guide groove 501, the top of the roller 503 extends to the outside of the base 1, and a clamping block 502 is installed at the top of the roller 503, and one side of the clamping block 502 is connected to one side of the guide block 8;

[0035] There are four limiting guide grooves 501, which are distributed in an X shape on the base 1, and the width of the clamping block 502 is adapted to the inner width of the clamping plate 4;

Since the roller 503 is always located inside the limiting guide groove 501, and the limiting guide groove 501 is distributed obliquely, the four 504 move inward, so that the guide blocks 8 are close to each other, so that the clamping block 502 contacts and clamps the other two sides of the workpiece, so as to increase the clamping and fixing area of ​​the workpiece, so that the workpiece is pushed to the center point, and workpieces of different sizes are limited;

[0040] Finally, when the workpiece is fixed, the hammer head in the electro-hydraulic hammer body 2 is started to move up and down to achieve the forging effect on the workpiece.
