Description

Technical Field

[0001] This utility model relates to the field of stator processing, specifically a stator processing device for cycloidal hydraulic motors. Background Technology

[0002] As a key component in the hydraulic system, the stator of a cycloidal hydraulic motor directly affects the motor's performance and service life due to its machining accuracy and surface quality. During stator machining, grinding and finishing processes are typically required, generating a large amount of metal shavings. To prevent shavings from splashing and polluting the working environment, and to avoid safety hazards to operators, a Chinese utility model patent (publication number: CN219819066U) discloses a general-purpose stator core grinding device for motor production. This device uses several baffles to block the shavings generated during grinding, reducing splashing. After contacting the baffles, the shavings fall into a collection chamber located inside the baffles, and then into a collection box connected to the lower side of the collection chamber. This effectively collects the grinding shavings and reduces shavings splashing.

[0003] However, the above-mentioned device still has some shortcomings in use: Specifically, there is a certain gap between two adjacent baffles. During the actual processing, the flying debris may fly out from these gaps, resulting in poor protection. At the same time, some debris falls onto the worktable and needs to be manually cleaned by the staff to fall into the collection chamber, which increases the workload of the staff. Therefore, in order to address the above situation, a cycloidal hydraulic motor stator processing device is proposed. Utility Model Content

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a device for processing the stator of a cycloidal hydraulic motor. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A cycloidal hydraulic motor stator processing device includes a base 1 and a support rod 6. A rectangular cavity 101 is provided on the base 1. A notch 102 is provided on the bottom surface of the inner wall of the rectangular cavity 101. A through groove 103 communicating with the rectangular cavity 101 is provided on the top of the base 1. A protective shell 3 is slidably fitted on the through groove 103.

[0028] An electric push rod 2 is provided on the bottom surface of the inner wall of the rectangular cavity 101. There are two electric push rods 2, and the moving ends of the two electric push rods 2 are fixedly connected to the outer wall of the protective shell 3.

[0029] A fixing block 4 is fixed to the bottom surface of the inner wall of the rectangular cavity 101. A material drop groove 401 is opened on the top of the fixing block 4. The material drop groove 401 is connected to the notch 102. An assembly groove 402 is opened on one side of the outer wall of the fixing block 4. A collection box 5 is slidably fitted on the assembly groove 402. A moving wheel 501 is provided at the bottom of the collection box 5. There are four moving wheels 501, which are distributed in a rectangular shape at the bottom of the collection box 5.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The base 1 has a support 9 on its top, and the support 9 has a grinding mechanism.

[0031] The grinding mechanism includes an electric lead screw module at the bottom of the fixed bracket 9. A lifting cylinder is fixed to the moving end of the electric lead screw module, and a grinding machine is fixed to the moving end of the lifting cylinder, which can lower the grinding machine to complete the grinding process on the stator core.

[0032] Reference Figure 2 , Figure 3 and Figure 4 The protective shell 3 is a cylindrical structure in the shape of a ring. The outer wall of the protective shell 3 is interference-fitted with a limit ring. The moving end of the electric push rod 2 is connected to the limit ring. The inner wall of the protective shell 3 is provided with a rubber pad.

[0033] The rubber pad installed on the inner wall of the protective shell 3 can buffer the debris generated during the grinding operation and protect the inner wall of the protective shell 3.

[0034] Reference Figure 1 , Figure 2 and Figure 3 Both sides of the outer wall of the support rod 6 are fixed with fixing rods 7. The fixing rods 7 are cylindrical in shape. The end of the fixing rod 7 away from the support rod 6 is fixed to the inner wall of the material drop trough 401. The end of the support rod 6 that passes through the through groove 103 is provided with a positioning mechanism 8.

[0035] Among them, the cylindrical fixing rod 7 can prevent the falling debris from accumulating on the fixing rod 7, thereby improving the debris collection efficiency. At the same time, the positioning mechanism 8 is used to fix the placed stator core to prevent movement during the grinding operation.

[0036] Accordingly, the composition structure of the positioning mechanism 8 is the same as that of the positioning component in the prior art (announcement number: CN219819066U), and will not be described in detail here.

[0037] Reference Figure 1 , Figure 2 and Figure 3The fixed block 4 is provided with a limiting component, which includes a rod fixed to the outer wall of the fixed block 4. A limiting plate is fitted on the rod with clearance. When the collection box 5 is inserted into the assembly groove 402 and cooperates with the discharge groove 401, the limiting plate is in contact with the surface of the collection box 5.

[0038] When the collection box 5 is pushed into the material discharge trough 401, the outer wall of the collection box 5 is flush with the side of the fixing block 4. At this time, the limiting plate is rotated and comes into contact with the outer wall of the collection box 5, which can limit the collection box 5.

[0039] Reference Figure 2 The outer wall of the collection box 5 is equipped with a handle.

[0040] Among them, the collection box 5 is made easy for staff to pick up by the addition of a handle.

[0041] Working principle: When in use, first connect the power supply and switch to the electrical equipment in this device. After placing the stator core to be processed on the positioning mechanism 8 for positioning, turn on the switch of the electric push rod 2. The electric push rod 2 will work to make the protective shell 3 slide and rise along the through groove 103. The grinding mechanism will be operated to perform grinding. The debris generated during the grinding process is completely blocked by the protective shell 3 and falls into the collection box 5 through the through groove 103 for collection. The staff can periodically remove the collection box 5 from the material drop trough 401 to centrally process the collected debris.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
