[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] Example 1

[0019] See also Figures 1 to 3In the embodiment of the present invention, the automatic lifting device for automobile transmission shaft workpiece 2 includes a ground workbench 1, automobile transmission shaft workpiece 2 and underground track rod 3. The ground workbench 1 is placed on the ground, and the underground track rod 3 is built into the ground. A track groove 4 is opened inside the underground track rod 3, and a cross bar 10 is provided on the side of the underground track rod 3. The cross bar 10 is used to limit the automobile transmission shaft workpiece 2 to improve the activity stability of the automobile transmission shaft workpiece 2. A track support plate 5 is movable inside the track groove 4. The bottom end of the automobile transmission shaft workpiece 2 moves on the track support plate 5. The top of the automobile transmission shaft workpiece 2 passes through the underground track rod 3 and the ground workbench 1 and extends to the top of the ground workbench 1. Two sets of pulleys 6 are respectively provided on the side of the underground track rod 3 near the top and bottom ends. The two sets of pulleys 6 guide the wire rope 7 respectively, so that the wire rope 7 can be guided and moved in the desired direction. The track support plate 5 The upper part is provided with a steel wire rope 7, and the inner wall of the track groove 4 is provided with a fixed shaft 8 near the top position. One end of the steel wire rope 7 is fixed on the fixed shaft 8, and a winch 9 built into the ground is provided next to the underground track rod 3. The other end of the steel wire rope 7 passes through the underground track rod 3 and extends to the winch 9 position after passing through two sets of slide grooves and is wound around the winch 9. The steel wire rope 7 is provided on the track support plate 5 to drive the track support plate 5 to move up and down. During operation, the winch 9 is first started to reel it up, which will drive the steel wire rope 7 to reel in. The reeling movement of the steel wire rope 7 will pull the track support plate 5 upward, so that the track support plate 5 can move upward along the underground track rod 3 on the underground track rod 3. In this way, the track support plate 5 drives the automobile transmission shaft workpiece 2 to move online, so that the automobile transmission shaft workpiece 2 is automatically lifted, thereby achieving the effect of automatically lifting the height of the automobile transmission shaft workpiece 2, without manual operation, avoiding the danger caused by manual cooperation operation, and also reducing labor intensity.

[0020] Example 2

[0021] See also Figures 1 to 3 In the embodiment of the present invention, a placement groove 11 is opened on the side of the underground track rod 3 near the top, and a pulley 6 is built into the placement groove 11. The pulley 6 is placed in the placement groove 11. This eliminates the need to tilt the steel wire rope 7 on the underground track rod 3, so that the steel wire ropes 7 on both sides of the automobile transmission shaft workpiece 2 are parallel to the automobile transmission shaft workpiece 2, greatly improving the activity stability of the track support plate 5 and the automobile transmission shaft workpiece 2. The other pulley 6 is installed on the side of the underground track rod 3 near the bottom through a fixed seat. One pulley 6 is located at the top of the underground track rod 3, and the other pulley 6 is located at the bottom of the underground track rod 3. This can drive the steel wire rope 7 to increase the activity range of the track support plate 5 to the maximum.
