Description

Technical Field

[0001] The utility model belongs to the field of automobile maintenance tools, and particularly relates to a cross shaft dismounting tool. Background Art

[0002] The cross shaft type rigid universal joint is a common mechanical transmission element, mainly used to connect two components with different axes in the transmission system.

[0003] The cross shaft is between the important components of the cross shaft type rigid universal joint. When one end of the universal joint rotates, the torque is transmitted to the other end through the cross shaft, and power can be effectively transmitted even if there is an angular deviation between the two shafts.

[0004] Currently, when disassembling the cross shaft, usually the cross shaft type rigid universal joint is placed on two cushion blocks, and a hammer is used in cooperation with a tool to strike the cross shaft, and the bearing housing is pushed out by the cross shaft. After the bearing housing is pushed out, the cross shaft can be easily removed.

[0005] Since the cushion blocks cannot stably support the cross shaft type rigid universal joint, during the knocking process, the cross shaft type rigid universal joint is prone to shaking, and if not careful, the bearing will be damaged.

[0006] Therefore, we propose a cross shaft dismounting tool to solve the above problems. Content of the Utility Model

[0007] Aiming at the problem that currently, when disassembling the cross shaft, usually a cushion block is used to support the cross shaft type rigid universal joint. Since the cushion block cannot stably support the cross shaft type rigid universal joint, during the knocking process, the cross shaft type rigid universal joint is prone to shaking, and if not careful, the bearing will be damaged, the utility model provides a cross shaft dismounting tool.

[0008] The solution adopted by the utility model to solve its technical problems is: a cross shaft dismounting tool, including a first base, a second base, a rotating arm, and a support member. A short support plate and a long support plate are welded on the top of the first base. The short support plate and the long support plate are arranged in parallel, one in front of the other, and a notch is opened at the upper end of the long support plate;

[0009] The support member is detachably installed between the short support plate and the long support plate for supporting the shaft part of the cross shaft type rigid universal joint;

[0010] The rotating arm is located above the support member. One end of the rotating arm is rotatably connected to the top end of the short support plate, and the other end is arranged in the notch;

[0011] The second base is arranged on one side of the first base, and two support seats are welded on its top. A groove for supporting the universal joint fork is arranged on the top of the support seat.

[0012] Preferably, through holes are respectively formed in the short support plate and the long support plate.

[0013] Preferably, the support member is a high-strength screw rod. The front and rear ends of the high-strength screw rod respectively pass through the front and rear through holes and are respectively threadedly connected with two fastening nuts.

[0014] Preferably, a fixing nut is mounted on the rotating arm, and an adjusting bolt is threadedly connected inside the fixing nut.

[0015] Preferably, it further includes two connecting bolts and two sleeves. The two sleeves are respectively welded on the second base. One end of the connecting bolt is welded on the first base, and the other end thereof passes through the sleeve. Threaded sections of the connecting bolts are threadedly connected with two clamping nuts, and the two clamping nuts are respectively arranged at two ends of the sleeve.
