And a return spring is fixed between the bottom surface of the bearing seat and the base.

And anti-skid thread grooves are fixed on the top surface of the U-shaped bearing plate and the bottom surface of the n-shaped pressing plate.

The base is fixed with a power supply interface and an external air pump interface, the base is fixed with a control panel, and a driving motor control switch, a lifting cylinder control button and a telescopic cylinder adjusting button are fixed on the control panel.

The utility model discloses has positive effect: the utility model discloses a structure sets up rationally, the simple operation, it not only can as required angle modulation inclination, can remove as required moreover to can satisfy the bent axle drilling demand of different situation, can remove at same angle moreover, thereby can accomplish the drilling demand that is in on the same straight line, be favorable to improving the efficiency of processing and the precision of drilling, the suitability is strong and the practicality is good.

Drawings

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the following specific embodiments, taken in conjunction with the accompanying drawings, in which:

fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

(example 1)

Fig. 1 shows a specific embodiment of the present invention, wherein fig. 1 is a schematic structural diagram of the present invention.

Referring to fig. 1, an angle-adjustable crankshaft drilling clamping device comprises a base 1, a bracket 2 arranged on the base, a clamping structure 3 arranged on the bracket, a bearing seat 4 arranged on the bracket, a lifting cylinder 6 fixed between the middle of the bearing seat and the middle of the bracket and having one end connected to the bracket via a rotating shaft 5, a piston shaft of the lifting cylinder connected to the middle of the bottom surface of the bearing seat via a movable shaft 7, an adjusting groove 8 arranged on the bearing seat and perpendicular to the movable shaft, a transmission screw 9 arranged in the adjusting groove, a driving motor 10 connected to the transmission screw and fixed to the side of the bearing seat, a slide block 11 arranged in the adjusting groove and connected to the transmission screw by screw thread, the clamping structure 3 comprises a clamping seat 31 and a U-shaped bearing plate 32 fixed on the clamping seat 31, a clamping support rod 33 is arranged on the clamping seat, an n-shaped pressing plate 34 is fixed on the clamping support rod, a telescopic cylinder 35 is fixed between the clamping support rod and the clamping seat, the n-shaped pressing plate is clamped and pressed on the U-shaped bearing plate under the action of the telescopic cylinder to clamp and position the crankshaft, and the clamping seat is fixed on the sliding block.
