Description

Technical Field

[0001] This utility model relates to the field of inspection tools, and in particular to an inspection tool for a stator sleeve of a cycloidal hydraulic motor. Background Technology

[0002] Cycloidal hydraulic motors, as a key actuator in hydraulic systems, play an important role in converting the liquid pressure energy provided by the hydraulic pump into the mechanical energy of the output shaft. The stator sleeve of a cycloidal hydraulic motor is a key component in a cycloidal motor.

[0003] In the traditional inspection process of stator sleeves for cycloidal hydraulic motors, specialized equipment is usually used to ensure that the accuracy of the parts meets the design requirements. However, this equipment inspection method has certain limitations, mainly in that the inspection cycle is long. The stator sleeve needs to be installed on the equipment and then a series of measurement and calibration operations are performed, which is often time-consuming. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cycloidal hydraulic motor stator sleeve inspection tool, which solves the problem of long inspection cycle for cycloidal hydraulic motor stator sleeves.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stator sleeve inspection fixture for a cycloidal hydraulic motor, comprising a stator inspection body, a mandrel disposed in the middle of the front side of the stator inspection body, a positioning pin disposed above the mandrel, and a pin disposed below the mandrel, the positioning pin and the pin being on the same vertical plane of the stator inspection body, and screws being provided through the upper and lower ends of the rear side of the stator inspection body, the front ends of the upper and lower screws being threadedly connected to the rear side of the positioning pin and the pin respectively.

[0006] Preferably, a double-ended stud is transversely disposed between the mandrel and the stator inspection body, the front side of the double-ended stud is threadedly connected to the stator inspection body, and the rear side of the double-ended stud is threadedly connected to a nut.

[0007] Preferably, a second washer is provided between the rear side of the double-ended stud and the stator inspection body, and the nut is provided on the rear side of the second washer.

[0008] Preferably, a handball is fixedly connected to the rear end of the double-ended stud.

[0009] Preferably, washers are provided at the contact points between the upper and lower screws and the stator inspection point.

[0010] Preferably, a washer is provided on one side of the pin, and the rear end of the washer is disposed inside the stator inspection body.

[0011] Beneficial effects

[0012] This utility model provides a cycloidal hydraulic motor stator sleeve inspection fixture. Compared with the prior art, it has the following advantages:

[0013] In this invention, by setting positioning pins and latches, during the inspection of the motor stator sleeve, the positioning pins and latches on the front side of the stator inspection fixture are respectively inserted into the pin tooth hole and bolt hole of the stator sleeve. The positioning pins and latches represent the positions of the pin tooth hole and bolt hole of the cycloidal hydraulic motor stator sleeve, respectively. Their relative positional relationship directly reflects the relative position of these two key holes on the stator sleeve. By simultaneously inserting the positioning pins and latches, the correct position of the stator sleeve on the inspection fixture can be ensured, thereby enabling accurate positional detection. In addition, since the positioning pins and latches are on the same vertical plane, it is also possible to detect whether the pin tooth hole and bolt hole are perpendicular to the vertical surface of the stator sleeve. The design of this inspection fixture simplifies the inspection steps, making the inspection process of the stator sleeve faster and significantly shortening the inspection cycle of the cycloidal hydraulic motor stator sleeve.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 This utility model provides two technical solutions, specifically including the following embodiments:

[0021] Example 1:

[0022] A cycloidal hydraulic motor stator sleeve inspection fixture includes a stator inspection body 1. A spindle 8 is disposed in the middle of the front side of the stator inspection body 1. A positioning pin 3 is disposed above the spindle 8, and a pin 9 is disposed below the spindle 8. It should be noted that the positioning pin 3 and the pin 9 represent the positions of the pin tooth hole and the bolt hole of the cycloidal hydraulic motor stator sleeve, respectively. Their relative positional relationship directly reflects the relative positional accuracy of these two key holes on the stator sleeve. The positioning pin 3 and the pin 9 are located on the same vertical plane of the stator inspection body 1. By inserting the positioning pin 3 and the pin 9 simultaneously, the correct position of the stator sleeve on the inspection body can be ensured, thereby enabling accurate positional detection. Screws 5 are provided through the upper and lower ends of the rear side of the stator inspection body 1. The front ends of the two screws 5 are threaded to the rear sides of the positioning pin 3 and the pin 9, respectively.

[0023] During operation, in the process of inspecting the motor stator sleeve, the positioning pin 3 and the bolt 9 on the front side of the stator inspection fixture 1 are inserted into the pin tooth hole and bolt hole of the stator sleeve, respectively. By inserting the positioning pin 3 and the bolt 9 at the same time, the correct position of the stator sleeve on the inspection fixture can be ensured, thereby enabling accurate positional testing. In addition, since the positioning pin 3 and the bolt 9 are on the same vertical plane, it is also possible to check whether the pin tooth hole and the bolt hole are perpendicular to the vertical surface of the stator sleeve. The inspection fixture is simple to operate and can be used without professional skills, reducing the skill requirements for operators.

[0024] Example 2:

[0025] Based on Embodiment 1, a double-ended stud 10 is transversely inserted between the mandrel 8 and the stator inspection body 1. The front side of the double-ended stud 10 is threadedly connected to the stator inspection body 1, and the rear side of the double-ended stud 10 is threadedly connected to a nut 7. A washer 6 is provided between the rear side of the double-ended stud 10 and the stator inspection body 1. The nut 7 is located behind the washer 6. The washer 6 is used to prevent the nut 7 from directly pressing on the stator inspection body 1 and to protect the surface of the inspection body from damage. A ball joint 11 is fixedly connected to the rear end of the double-ended stud 10. Washers 4 are provided at the contact positions of the upper and lower screws 5 and the stator inspection body 1. A washer 2 is provided on one side of the pin 9. The rear end of the washer 2 is inserted through the interior of the stator inspection body 1. The washer 2 limits the maximum insertion depth of the pin 9 and ensures that the pin 9 does not over-insert into the stator sleeve, thereby avoiding possible damage to the internal structure of the stator sleeve.

[0026] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
