[0002] Automobile shock absorber is a key component in the automobile suspension system. It absorbs and attenuates the vibration caused by uneven road surface or acceleration and deceleration of the vehicle through hydraulic or hydraulic means, thereby improving the driving smoothness and comfort of the vehicle. The piston rod is one of the core components of the shock absorber. It is the component connecting the cylinder and the piston, and is responsible for absorbing the energy during the compression and extension process of the shock absorber.

[0003] When processing some automobile shock absorber piston rods, it is often necessary to use a drilling machine to drill holes. The traditional way of drilling holes is to hold the piston rod by hand to drill holes. However, without the fixation of a clamp, it is very easy to cause the drilling position to be cheap. In addition, due to the material of some piston rods, the drilling process is slow, and long-term hand support can easily cause fatigue, and there are certain safety hazards. Utility Model Content

[0020] Among them, a second clamping rod 8 is fixedly connected to the surface of one side of the first connecting plate 6, and the second clamping rod 8 is against the inner wall of the piston rod body 2. A clamping mechanism 4 is provided on the surface of the first connecting plate 6 adjacent to the second clamping rod 8. The second clamping rod 8 can be against the lower side of the inner wall of the piston rod body 2, and the piston rod body 2 is pressed onto the workbench through the second clamping rods 8 on both sides.

[0021] In addition, the adjustment seat 5 includes a connecting block 51, a plate body arranged on the rear side of the connecting block 51 is installed on the bottom output end of the electric lifting device 3, a first connecting plate 6 is fixedly connected to the front surface of the connecting block 51, and a second screw 52 is arranged on the side wall surface of one side of the connecting block 51. The lifting and lowering of the electric lifting device 3 changes the height of the adjustment seat 5, thereby changing the height of the first connecting plate 6 and the second connecting plate 7 on both sides.

[0022] Moreover, a sliding rod 53 is provided on one side adjacent to the second screw rod 52, and a second connecting plate 7 is provided to slide on the sliding rod 53, and the second connecting plate 7 is penetrated on the second screw rod 52, and second nuts 9 are symmetrically provided on both sides of the second connecting plate 7 on the second screw rod 52, and the second connecting plate 7 can slide on the sliding rod 53, thereby changing the spacing between the second connecting plate 7 and the first connecting plate 6, so that piston rod bodies 2 of different lengths can be clamped.

[0023] In addition, a movable hole 71 is opened through the plate body of the second connecting plate 7, and the aperture of the movable hole 71 is larger than the outer diameter of the thread of the second screw rod 52. A second clamping rod 8 is fixedly connected to the surface of one side of the plate body of the second connecting plate 7. A clamping mechanism 4 is provided on the upper surface of the plate body of the second connecting plate 7. The movable hole 71 facilitates the second connecting plate 7 to not be restricted by the second screw rod 52 and only slide on the sliding rod 53. The through hole on one side of the movable hole 71 is used to be set to slide on the sliding rod 53, and the aperture of the through hole is consistent with the diameter of the sliding rod 53.

[0024] Moreover, the clamping mechanism 4 includes a first screw 41, which is symmetrically and vertically fixed on the upper end surfaces of the first connecting plate 6 and the second connecting plate 7 respectively.

[0025] In this embodiment, when using the drilling machine body 1 to drill a hole in the piston rod body 2, first place the piston rod body 2 on the workbench, loosen the second nut 9 and slide the second connecting plate 7 so that the distance between the second connecting plate 7 and the first connecting plate 6 is convenient for the piston rod body 2 to be placed in, and then fit the piston rod body 2 to the first connecting plate 6 so that the second clamping rod 8 on the first connecting plate 6 can be located in the inner cavity of the piston rod body 2, and then the second connecting plate 7 can be adjusted.

[0026] The second connecting plate 7 is slid on the sliding rod 53 so that the second clamping rod 8 on the second connecting plate 7 can enter the inner cavity on the other side of the piston rod body 2, and then the second nuts 9 on both sides of the second connecting plate 7 on the second screw rod 52 can be rotated so that the second nuts 52 can be fitted and tightened on both sides of the second connecting plate 7 to fix the second connecting plate 7.

[0027] At the same time, when tightening the first connecting plate 6 and the second connecting plate 7 on both sides, adjust the clamping mechanism 4, unscrew the first nuts 43 on both sides of the chuck 42 from the chuck, so that the chuck 42 can move up and down, and then adjust the chuck 42 to a suitable height so that the chuck 42 can be inserted into the side wall of the piston rod body 2, and then tighten the first nuts 43 on both sides so that the first clamping rod 421 can abut against the upper end of the inner wall of the piston rod body 2, thereby cooperating with the second clamping rod 8 to abut against the lower end of the inner wall to clamp and fix the piston rod body 2. In this way, piston rod bodies 2 of different lengths or diameters but with the same wall thickness and different sizes can be clamped and fixed.

[0028] Furthermore, a rubber layer is provided on the surface of the first clamping rod 421 and the second clamping rod 8 to prevent the workpiece from being damaged by the clamping.
