Description

Technical Field

[0001] The utility model belongs to the technical field of processing equipment for cycloidal hydraulic motors, and particularly relates to a positioning tooling for a stator of a cycloidal hydraulic motor. Background Technique

[0002] A cycloidal hydraulic motor is a positive displacement hydraulic motor, which mainly consists of key components such as a stator, a rotor, and a distribution plate. Among them, the stator has a special inner contour curve, usually a closed curve composed of multiple arcs. The rotor makes a planetary motion inside the stator. During the assembly process of the cycloidal hydraulic motor, the stator needs to be accurately positioned inside the housing. If parameters such as the central position and the axis perpendicularity of the stator deviate, it will cause uneven gaps between the rotor and the stator. Therefore, a positioning tooling for the stator of the cycloidal hydraulic motor is required to position and clamp it during assembly.

[0003] However, during the use of the existing positioning tooling for the stator of the cycloidal hydraulic motor, it is not convenient for precise positioning. Operators need to spend more time understanding the working principle and operation process of the tooling, which increases the operation difficulty and time cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a positioning tooling for a stator of a cycloidal hydraulic motor. By setting a positioning mechanism, it solves the problem that during the use of the existing positioning tooling for the stator of the cycloidal hydraulic motor, it is not convenient for precise positioning, and operators need to spend more time understanding the working principle and operation process of the tooling, thus increasing the operation difficulty and time cost.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a positioning tooling for a stator of a cycloidal hydraulic motor, which includes a tooling support plate. A positioning mechanism and a clamping mechanism are arranged on the tooling support plate;

[0007] A plurality of support legs are fixedly connected to the bottom of the tooling support plate. The positioning mechanism includes a positioning component and a driving component. The positioning component includes a plurality of rectangular support blocks fixedly connected to the top of the tooling support plate. Two sliding rods are fixedly connected between the plurality of rectangular support blocks. Two moving plates are slidably connected to the outer walls of the two sliding rods. A rotating shaft one is rotatably connected to the top of the tooling support plate, and a gear is fixedly connected to the outer wall of the rotating shaft one.

[0008] Furthermore, racks are fixedly connected to the tops of the two moving plates, and L-shaped limiting plates are fixedly connected to the tops of the two moving plates. One side of each of the two racks away from each other slidably penetrates through the two L-shaped limiting plates respectively.

[0009] Furthermore, a plurality of second rotating shafts are rotatably connected to the top of the tooling support plate. Limiting rollers are fixedly connected to the outer walls of the plurality of second rotating shafts. The mutually remote sides of the two racks respectively slide and extend into the plurality of limiting rollers.

[0010] Furthermore, the driving assembly includes a hydraulic cylinder disposed below the tooling support plate. Two hydraulic cylinder fixing sleeves are fixedly connected to the outer wall of the hydraulic cylinder. The tops of the two hydraulic cylinder fixing sleeves are fixedly connected to the tooling support plate.

[0011] Furthermore, a sliding groove is formed in the tooling support plate. A connecting plate is fixedly connected to the output shaft of the hydraulic cylinder. The top of the connecting plate slidably penetrates through the sliding groove and is fixedly connected to the moving plate.

[0012] Furthermore, the clamping mechanism includes support rods respectively fixedly connected to the tops of the two connecting plates. Clamping plates are fixedly connected to the mutually approaching sides of the two support rods.

[0013] Furthermore, placing plates are fixedly connected to the mutually approaching sides of the two clamping plates. Buffer gaskets are fixedly connected to the mutually approaching sides of the two clamping plates.

[0014] The utility model has the following beneficial effects:

[0015] 1. By providing a positioning mechanism, when tooling a hydraulic motor is required, the hydraulic motor to be tooled can be placed on the placing plate. Start the hydraulic cylinder on the hydraulic cylinder fixing sleeve. The hydraulic cylinder drives the moving plate on the right side to move leftward through the connecting plate. When the moving plate moves leftward, it drives the placing plate on the right side to move leftward through the gear and the rack. The two placing plates approach each other to complete precise centering positioning, so that the assembly error of the hydraulic motor caused by inaccurate placement plate position can be minimized to the greatest extent, thereby ensuring that the relative position relationship between the components inside the hydraulic motor after assembly is more accurate, which helps to improve the performance and working efficiency of the hydraulic motor;

[0016] 2. By providing a clamping mechanism, when positioning the hydraulic motor, due to the mutual approach of the moving plates, the clamping plates on the two support rods also approach each other. After positioning is completed, the two buffer gaskets will stably clamp the hydraulic motor. The clamping of the clamping plates further restricts the degree of freedom of the hydraulic motor from the side, keeping the hydraulic motor in a stable position in three-dimensional space and ensuring that its position accuracy is effectively maintained. Moreover, the buffer gaskets can also adapt to the possible irregular shape or surface roughness of the hydraulic motor housing, making the clamping force more evenly distributed on the surface of the hydraulic motor and further enhancing stability.

[0017] Certainly, when implementing any product of the utility model, it is not necessarily required to simultaneously achieve all the above-mentioned advantages. Brief Description of the Drawings

[0027] Please refer to Figures 1-5As shown in the figure, the utility model relates to a positioning tooling for a cycloid hydraulic motor stator, which comprises a tooling support plate 1. A positioning mechanism 2 and a clamping mechanism 3 are arranged on the tooling support plate 1. A plurality of support legs 101 are fixedly connected to the bottom of the tooling support plate 1. The positioning mechanism 2 comprises a positioning component 21 and a driving component 22. The positioning component 21 comprises a plurality of rectangular support blocks 211 fixedly connected to the top of the tooling support plate 1. Two slide bars 212 are fixedly connected between the plurality of rectangular support blocks 211. Two moving plates 213 are slidably connected to the outer walls of the two slide bars 212. A first rotating shaft 214 is rotatably connected to the top of the tooling support plate 1. A gear 215 is fixedly connected to the outer wall of the first rotating shaft 214. Rack bars 216 are fixedly connected to the tops of the two moving plates 213. L-shaped limiting plates 217 are fixedly connected to the tops of the two moving plates 213. The two rack bars 216 slide through the two L-shaped limiting plates 217 respectively on the sides away from each other. A plurality of second rotating shafts 218 are rotatably connected to the top of the tooling support plate 1. Limiting rollers 219 are fixedly connected to the outer walls of the plurality of second rotating shafts 218. The two rack bars 216 slide and extend into the plurality of limiting rollers 219 respectively on the sides away from each other. The driving component 22 comprises a hydraulic cylinder 221 arranged below the tooling support plate 1. Two hydraulic cylinder fixing sleeves 222 are fixedly connected to the outer wall of the hydraulic cylinder 221. The tops of the two hydraulic cylinder fixing sleeves 222 are fixedly connected to the tooling support plate 1. A chute 223 is formed in the tooling support plate 1. A connecting plate 224 is fixedly connected to the output shaft of the hydraulic cylinder 221. The top of the connecting plate 224 slides through the chute 223 and is fixedly connected to the moving plate 213. By setting the positioning mechanism, the assembly error of the hydraulic motor caused by the inaccurate position of the placement plate can be minimized, so as to ensure that the relative position relationship between the internal components of the hydraulic motor after assembly is more accurate, which helps to improve the performance and working efficiency of the hydraulic motor.

[0028] The clamping mechanism 3 comprises support rods 301 respectively fixedly connected to the tops of the two connecting plates 224. Clamping plates 302 are fixedly connected to the sides of the two support rods 301 close to each other. A placement plate 303 is fixedly connected to the side of each of the two clamping plates 302 close to the other. Buffer gaskets 304 are fixedly connected to the sides of the two clamping plates 302 close to each other. By setting the clamping mechanism, the clamping of the clamping plates 302 further restricts the freedom degree of the hydraulic motor from the side, so that the hydraulic motor maintains a stable position in the three-dimensional space, ensuring that its position accuracy is effectively maintained. Moreover, the buffer gaskets 304 can also adapt to the possible irregular shape or surface roughness of the hydraulic motor housing, making the clamping force more evenly distributed on the surface of the hydraulic motor, further enhancing the stability.

[0029] A specific application of this embodiment is as follows: When in use, first place the device at the corresponding position, place the hydraulic motor to be tooled on the placing plate 303, start the hydraulic cylinder 221 on the hydraulic cylinder fixing sleeve 222. The hydraulic cylinder 221 drives the moving plate 213 on the right side to move leftward through the connecting plate 224. When the moving plate 213 moves leftward, it drives the placing plate 303 on the right side to move leftward through the gear 215 and the rack 216. The two placing plates 303 approach each other to complete precise centering positioning, so as to minimize the assembly error of the hydraulic motor caused by inaccurate placement plate position, thereby ensuring that the relative position relationship between the components inside the hydraulic motor after assembly is more accurate, which helps to improve the performance and working efficiency of the hydraulic motor. When positioning the hydraulic motor, due to the approaching of the moving plates 213, the clamping plates 302 on the two support rods 301 also approach each other. After positioning, the two buffer gaskets 304 will firmly clamp the hydraulic motor. The clamping of the clamping plates 302 further restricts the freedom degree of the hydraulic motor from the side, keeping the hydraulic motor in a stable position in three-dimensional space and ensuring that its position accuracy is effectively maintained. Moreover, the buffer gaskets 304 can also adapt to the possible irregular shape or surface roughness of the hydraulic motor housing, making the clamping force more evenly distributed on the surface of the hydraulic motor and further enhancing stability.
