Description

Technical Field

[0001] The utility model relates to the field of mechanical manufacturing, in particular to a centering device for parts of a crankshaft. Background Art

[0002] In addition to transmitting torque to the camshaft, the functions of the gears at both ends of the existing engine crankshaft also need to meet the accuracy of power output for fuel supply and gas distribution. Therefore, during assembly, it is necessary to ensure the angular position of the gears. When assembling the gears, manual assembly is generally carried out through an auxiliary tooling for positioning. However, during the process of manually assembling the gears using the auxiliary tooling, due to inaccurate angular positioning of the crankshaft workpiece and inaccurate gear positioning, the angular position of the gears deviates, which in turn affects the accuracy of engine fuel supply and gas distribution. In order to ensure the stability of the assembly process and the quality after assembly, there is an urgent need for a mechanism to improve the gear assembly effect. Content of the Utility Model

[0003] To solve the above problems, the utility model discloses a gear assembly positioning and anti-mistake device for a crankshaft.

[0004] The specific technical solution is as follows:

[0005] A gear assembly positioning and anti-mistake device for a crankshaft is provided with a bottom plate. A V-shaped support seat is arranged on the bottom plate. An angular positioning seat is arranged on one side of the rear end of the V-shaped support seat. A crankshaft axial positioning seat is arranged on one side of the rear end of the angular positioning seat. A gear axial positioning seat is arranged on one side of the rear end of the crankshaft axial positioning seat. A cylinder positioning seat is arranged on one side of the rear end of the gear axial positioning seat. A cylinder is arranged on the cylinder positioning seat. A gear positioning mechanism is also arranged on the bottom plate.

[0006] A position sensor is arranged on the angular positioning seat. A position controller is arranged at the end of the bottom plate. The position controller is connected to the cylinder and the position sensor through a solenoid valve.

[0007] A guide rail is arranged on the bottom plate. The gear positioning mechanism includes a gear support frame that can slide on the guide rail. The upper cross-section of the gear support frame is circular. Gear positioning keys are circumferentially distributed on the circle.

[0008] The advantages of the utility model are: there is no manual adjustment link, and the assembly accuracy is further improved through direct transportation by the gear positioning mechanism. A cylinder is set to ensure that the gear positioning mechanism will not interfere with the crankshaft before the crankshaft is placed. Description of the Drawings

[0011] Figure 3 is the left view of Figure 1 . Specific embodiments

[0012] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0013] An anti-misalignment device for assembling and positioning a crankshaft gear is provided with a bottom plate 1, on which a V-shaped support seat 2 is arranged. An angular positioning seat 3 is arranged on one side at the rear end of the V-shaped support seat 2. A crankshaft axial positioning seat 4 is arranged on one side at the rear end of the angular positioning seat 3. A gear axial positioning seat 5 is arranged on one side at the rear end of the crankshaft axial positioning seat 4. A cylinder positioning seat 6 is arranged on one side at the rear end of the gear axial positioning seat 5. A cylinder 6a is arranged on the cylinder positioning seat. A gear positioning mechanism 7 is also arranged on the bottom plate 1.

[0014] A position sensor 3a is arranged on the angular positioning seat. A position controller 8 is arranged at the end of the bottom plate. The position controller 8 is connected to the cylinder 6a and the position sensor 3a through a solenoid valve 8a.

[0015] A guide rail 11 is arranged on the bottom plate 1. The gear positioning mechanism 7 includes a gear support frame 9 that can slide on the guide rail. The upper cross-section of the gear support frame 9 is circular, and gear positioning keys 10 are circumferentially distributed on the circle.

[0016] The working principle of the present utility model is as follows: Place the crankshaft workpiece on the main body of the present application, and at the same time make the crankshaft connecting rod lean against the angular positioning seat. At this time, the position sensor on the angular positioning seat generates a signal (indicating that the position of the crankshaft has been placed correctly and waiting for assembly) and transmits it to the position controller. The position controller controls the cylinder to retract through the solenoid valve to ensure that the gear positioning mechanism can slide on the guide rail. Then place the gear to be assembled in the gear positioning keys. At this time, the gear is directly opposite to the center of the crankshaft end. Continue to move the gear support frame on the guide rail to make the gear lean against the crankshaft end, and then push the gear in to complete the assembly.
