[0001] The utility model relates to the technical field of motor parallelism detection, in particular to a rotary DD motor parallelism detection tooling. Background Technique

[0002] The end face of the motor housing or pump housing has high flatness and roughness requirements. After machining the end face and the step face in one clamping, further finishing such as grinding is still required. When performing subsequent finishing such as grinding on the end face, the parallel accuracy relative to the step face must be well controlled, otherwise it will affect the running-in state and service life of the hydraulic motor or hydraulic pump.

Specific embodiments

[0024] In order to have a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described with reference to the accompanying drawings.

[0025] Embodiment 1

[0026] As Figures 1-5 shown, the present utility model provides a technical solution: a rotary DD motor parallelism detection tooling, including a rotating base 1, a rotating platform 2 disposed on the upper part of the rotating base 1, and a connecting component 3 disposed on the upper part of the rotating base 1. The connecting component 3 includes a disassembly and assembly mechanism 31 disposed on the upper part of the rotating base 1. An auxiliary mechanism 32 is disposed on the upper part of the rotating base 1, and a fixing hole is disposed at the bottom of the rotating base 1. The disassembly and assembly mechanism 31 includes a bearing retaining ring 311 connected to the lower part of the rotating platform 2. A bearing 313 is connected to the lower part of the bearing retaining ring 311. A lower bearing retaining ring 312 is connected to the upper part of the rotating base 1. A placing table 314 is disposed on the upper part of the rotating platform 2. A positioning groove 315 is formed on the upper part of the rotating platform 2. A positioning block 316 is disposed on the inner wall of the positioning groove 315. A clamping groove 317 is formed on one side of the positioning block 316. A magnet 318 is fixedly connected to the inner wall of the clamping groove 317. An installation groove 319 is formed inside the rotating platform 2. An installation block 3110 is slidably connected to the inner wall of the installation groove 319. A clamping rod 3111 is fixedly connected to one side of the installation block 3110. A connecting rod 3112 is movably connected to one side of the rotating platform 2. A spring 3113 is fixedly connected to the inner wall of the installation groove 319.

[0027] In this embodiment, a plurality of threaded holes are formed in the upper part of the placing table 314, and the upper part of the positioning block 316 is fixedly connected to the placing table 314. Through the cooperation of the rotating base 1, the bearing pressing ring 311, the bearing lower pressing ring 312, the bearing 313, the rotating platform 2, and the placing table 314, the error generated when manually moving the height gauge can be effectively reduced, and the working efficiency can be greatly improved, and the operation burden can be reduced.

[0028] Further, one end of the spring 3113 is fixedly connected to the mounting block 3110, and the inner end of the connecting rod 3112 is fixedly connected to the mounting block 3110. Through the cooperation of the positioning block 316, the positioning groove 315, the clamping rod 3111, the clamping groove 317, the mounting block 3110, the connecting rod 3112, and the spring 3113, it is convenient for manual replacement of the placing table 314, and it is prevented that the threaded holes formed in the upper part of the placing table 314 are worn after repeated use and the workpiece cannot be fixed.

[0029] Furthermore, the clamping rod 3111 is made of iron material, and the clamping rod 3111 movably penetrates through the rotating platform 2 and is clamped with the clamping groove 317. Under the action of the suction force of the magnet 318, the clamping effect of the clamping rod 3111 and the clamping groove 317 can be better, so that the placing table 314 can be more stable during use.

[0030] When the device is in use, first, manually assemble the rotating base 1, the bearing 313, and the rotating platform 2 together. Then, fix the rotating base 1 on a flat marble through the fixing holes at the bottom. Next, place the motor to be measured on the placement table 314 and lock it tightly with corresponding bolts through the surface threaded holes. Place the height gauge on one side and take readings on the end face of the motor to be measured. Rotate the rotating platform 2 and then observe the change in the readings of the height gauge to measure the parallelism of the motor end face. Compared with placing the motor on the marble and then moving the height gauge around the motor for one week and observing the readings, this mechanism has higher precision, can avoid errors caused by manual pushing, and using this tooling can also reduce the operation difficulty and labor intensity, greatly improving the work efficiency. Further, when it is necessary to disassemble the placement table 314, first, manually pull the connecting rod 3112 outward to drive the mounting block 3110 to move outward, so that the clamping rod 3111 fixedly connected to one side of the mounting block 3110 can move outward, and then the clamping rod 3111 can be separated from the clamping groove 317. Subsequently, the placement table 314 can be manually taken out upward, which is convenient for manual replacement of the placement table 314 and can prevent the threaded holes opened on the upper part of the placement table 314 from being worn after multiple uses and unable to fix the workpiece. When it is necessary to install the placement table 314, only need to manually pull the connecting rod 3112 outward, then match the positioning block 316 fixedly connected to the lower part of the placement table 314 with the positioning groove 315, and then release the connecting rod 3112. Under the action of the elastic force of the spring 3113, the mounting block 3110 can move inward, so that the clamping rod 3111 can be clamped with the clamping groove 317, and then the placement table 314 can be fixed, and the replacement operation is simple and convenient, which is convenient for manual operation.

[0031] Embodiment 2

[0032] On the basis of Embodiment 1, a preferred embodiment of a rotary DD motor parallelism detection tooling provided by the present utility model is as Figures 1 to 5 shown: The auxiliary mechanism 32 includes a rotating rod 321 rotatably connected to the outer end of the connecting rod 3112. The inner side of the rotating rod 321 is fixedly connected with a positioning rod 322. The outer side of the rotating platform 2 is provided with a positioning hole 323, and the outer side of the rotating platform 2 is provided with a groove 324.

[0033] In this embodiment, the positioning rod 322 is clamped in the positioning hole 323, and the positioning rod 322 is adapted to the groove 324. Through the cooperation of the rotating rod 321, the positioning rod 322, the positioning hole 323, and the groove 324, the clamping rod 3111 can be stopped at a position away from the clamping groove 317, so that the hands of the operator can be freed, and it is more convenient for the operator to disassemble and assemble the placement table 314.

[0034] When the connecting rod 3112 moves outward, since the rotating rod 321 is rotatably connected to the outer end of the connecting rod 3112, the outward movement of the connecting rod 3112 can cause the rotating rod 321 to move outward, and thus the positioning rod 322 fixedly connected to the inner side of the rotating rod 321 can move outward. When the positioning rod 322 moves outward and separates from the positioning hole 323, by manually rotating the rotating rod 321 and matching the positioning rod 322 with the groove 324, and at the same time under the action of the elastic force of the spring 3113, the clamping rod 3111 can stay at a position away from the clamping groove 317, so that the worker can free his hands, and it is more convenient for the worker to disassemble and assemble the placing table 314.
