Description

Technical Field

[0001] This utility model relates to the field of engine production equipment technology, and in particular to a positioning device for tightening shock absorbers. Background Technology

[0002] The crankshaft is the most important component in an engine. It bears the force transmitted from the connecting rods and converts that force into torque, which is then output through the crankshaft to drive other engine accessories. When adding fuel to the engine, the shock absorbers need to be tightened. However, relative slippage between the shock absorbers and the crankshaft can cause angular problems, preventing them from being properly positioned and fixed to the engine. Current technologies mostly use a flywheel mounted on the shock absorber, and then use the flywheel to position it against the engine. However, this method is not suitable for all engines, such as range-extended engines. Some range-extended engines cannot use flywheel positioning, and using a flywheel for positioning requires a large operating space and is costly. Utility Model Content

[0003] The technical problem to be solved by this utility model is that some engines cannot use the flywheel to position the shock absorber, and using the flywheel for positioning requires a large operating space and is costly. This utility model provides a positioning device for tightening the shock absorber.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] The disc bearing is mounted on one side of the mounting plate, and the tightening gun is mounted on the other side. The tightening gun is used to tighten the shock absorber.

[0008] The variable frequency motor is installed at the lower end of the mounting plate, on the same side as the tightening gun.

[0018] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0019] Example 1

[0020] like Figure 1-2 As shown, this embodiment provides a positioning device for tightening a shock absorber. This positioning device is installed beside the engine roller conveyor to fix the shock absorber, thus achieving relative fixation between the shock absorber and the engine crankshaft. The positioning device includes: a chuck 1, a mounting plate 2, a disc bearing 3, a variable frequency motor 4, and a tightening gun 5. The chuck 1 is connected to the disc bearing 3 and is used to clamp the shock absorber. The disc bearing 3 is mounted on one side of the mounting plate 2, and the tightening gun 5 is mounted on the other side. The tightening gun 5 is used to tighten the shock absorber. The variable frequency motor 4 is installed at the lower end of the mounting plate 2, on the same side as the tightening gun 5. In this embodiment, the chuck 1 passes through the mounting plate 2 and connects to the tightening gun 5. After the chuck 1 is clamped to the process hole of the shock absorber, the tightening gun 5 can be used to tighten the shock absorber to ensure a secure fixation.

[0021] In this embodiment, the chuck 1 is connected to the disc bearing 3 via a spring rod 6 and a rotating shaft 7, with the rotating shaft 7 sleeved on the spring rod 6. The chuck 1 includes a toothed plate 11 and a base plate 12. The base plate 12 is mounted on the spring rod 6, and the toothed plate 11 is mounted in the middle position of the base plate 12. The toothed plate 11 includes several stops 13. Specifically, the chuck 1 contacts the shock absorber. The position of the chuck 1 can be adjusted via the spring rod 6 and the rotating shaft 7 so that the toothed plate of the chuck 1 can be aligned with the process hole of the shock absorber. The chuck 1 includes four stops 13, which are distributed around the toothed plate 11 for clamping the shock absorber.

[0022] like Figure 2 As shown, in this embodiment, the mounting plate 2 is also provided with a pinion 8, which meshes with the disc bearing 3; wherein, the pinion 8 is connected to the variable frequency motor 4 through a connecting shaft. Specifically, the variable frequency motor 4 is mounted on the motor mounting plate, one end of the connecting shaft is connected to the motor mounting plate, and the other end passes through the mounting plate 2 and is connected to the shaft of the pinion 8, driving the variable frequency motor 4. When the variable frequency motor 4 rotates, the pinion 8 can be driven to rotate under the action of the connecting shaft.

[0023] This embodiment provides a positioning device for tightening a shock absorber. The positioning device is installed next to the engine roller conveyor. It uses a chuck to contact the shock absorber, and a variable frequency motor drives a meshing pinion and a disc bearing to rotate. Under the action of the rotating shaft, the connected chuck rotates and clamps the shock absorber. The variable frequency motor continues to drive the chuck forward, pushing the teeth in the chuck into the process holes of the shock absorber. This controls the tightening gun to tighten the screws, thereby fixing the shock absorber and achieving relative fixation between the shock absorber and the engine crankshaft. No additional flywheel is needed for shock absorber fixation, it is suitable for all engines, and does not occupy extra space in the engine bay.

[0024] The working principle of this utility model is as follows: The positioning device is installed next to the engine roller conveyor. The chuck 1 is brought into contact with the shock absorber. The variable frequency motor 4 is turned on, and the variable frequency motor 4 rotates, driving the pinion 8 to rotate. Since the pinion 8 meshes with the disc bearing 3, the rotation of the pinion 8 will drive the disc bearing 3 to rotate as well. Under the action of the spring rod 6 and the rotating shaft 7, the connected chuck 1 is rotated to lock the shock absorber. The variable frequency motor 4 continues to drive the forward push of the insert teeth 11 in the chuck 1 into the process hole of the shock absorber. The tightening gun 5 is controlled to tighten the screw, thereby fixing the shock absorber and achieving relative fixation between the shock absorber and the engine crankshaft.

[0025] Example 2

[0026] Example 1 implements a system where a variable frequency motor 4 pneumatically drives two meshing pinions 8 and a disc bearing 3 to rotate. Under the action of a spring rod 6 and a rotating shaft 7, the connected chuck 1 rotates and clamps the shock absorber. The variable frequency motor 4 continues to drive the chuck 1 forward, pushing the teeth 11 in the chuck 1 into the process holes of the shock absorber, thereby fixing the shock absorber and achieving relative fixation between the shock absorber and the engine crankshaft. However, this requires manual intervention to first make contact between the chuck 1 and the shock absorber before turning on the variable frequency motor 4, which is somewhat cumbersome and only allows for fixing in a single engine position, lacking flexibility. Therefore, based on Example 1, this example designs an additional drive device combined with a positioning device for tightening the shock absorber to achieve automatic drive, fixing, and tightening of the shock absorber in multiple engine positions, thus achieving multi-engine position fixation of the shock absorber.

[0027] In this embodiment, the drive unit includes a base, a cylinder, and a slide rail. The positioning device is mounted on the drive unit via a connecting plate. Driven by the cylinder, the positioning device moves forward along the slide rail to contact the shock absorber and then fixes the shock absorber, thus achieving automatic drive and fixation. Furthermore, the drive unit can achieve automatic drive in the X, Y, and Z directions, enabling the fixing of shock absorbers in multiple locations across different models, thereby improving work efficiency.

[0028] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
