Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, and more specifically, to a high-precision processing device for inner holes of shaft parts. Background Art

[0002] Shaft inner hole processing is a commonly used processing method in mechanical processing. The inner hole has different functions on different parts, and different inner hole structures have different requirements for their precision and smoothness. In the process of inner hole processing, it will first be processed with a fine drill bit, and then the drill bit diameter will be gradually increased to process the inner hole. Since the drill bit processing will make the inner hole surface rough and uneven, the inner hole surface needs to be further polished after the inner hole is processed to make the inner hole surface smooth. In the existing technology, when high-precision shaft inner hole processing equipment processes the shaft inner hole, most of them are single processing stations to process a separate shaft, and the shaft cannot achieve the effect of automatic loading and unloading. The slow time of manual loading and unloading leads to reduced equipment processing efficiency, and there are safety hazards in manual loading and unloading.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a high-precision processing device for the inner hole of shaft parts, including a body and a grinding component arranged on the body, the body is provided with a mounting ring, a limit plate is rotatably arranged in the mounting ring and is in contact with the inner wall thereof, the limit plate has a plurality of clamping grooves in an annular array, the mounting ring has a plurality of clamping plates corresponding to the plurality of clamping grooves in an annular array, the limit plate has a plurality of clamping cylinders in an annular array, and the plurality of clamping cylinders are respectively fixedly connected to the plurality of clamping plates, and loading components and discharge ports are respectively arranged on both sides of the plurality of clamping grooves, and a pushing component corresponding to the discharge port is arranged in the clamping groove.

[0006] Preferably, the loading assembly includes a feed plate with a feed trough, and two push plates rotatably arranged on a mounting ring, the two push plates are arranged corresponding to the two side walls of the feed trough, the push plate has a circular array with a number of trough bodies corresponding to the shaft diameter, a servo motor for driving a number of push plates to rotate is arranged on the machine body, and the end of the feed trough is arranged to be inclined downward toward the limit plate.

[0007] Preferably, the pusher assembly includes a push plate corresponding to the side wall of the shaft, and an elastic member is provided on one side of the push plate, and the elastic member has elastic potential energy for pushing the push plate away from the axis of the limiting disk.

[0008] The utility model has the following beneficial effects:

[0009] When the equipment is operating, the staff places the shaft in the feed trough and starts the equipment. When the limit plate rotates to correspond to the clamping groove and the feed trough, the shaft is pushed toward the clamping groove through the groove bodies on the two push plates. After the shaft is transported to the clamping groove, the limit plate is continued to be rotated so that the clamping groove corresponds to the clamping plate, the clamping cylinder is started to push the clamping plate to fix the shaft in the clamping groove, and then the inner hole of the shaft is polished by the polishing assembly.

[0017] In the above embodiment, it should be noted that a motor for driving the limit plate 3 to rotate is installed on the body 1, and the grinding assembly is a prior art. The grinding assembly and the motor are not shown in the figure. When the limit plate 3 rotates, the clamping groove 4 corresponds to the loading assembly 8, and then the shaft body is pushed into the clamping groove 4 through the loading assembly 8, and then the limit plate 3 is rotated to make the clamping groove 4 correspond to the clamping plate 6, and the clamping cylinder 7 is started to push the supporting plate to fix the shaft in the clamping groove 4, and then the inner hole of the shaft is processed by the grinding assembly on the body 1. After the processing is completed, the limit plate 3 is rotated, so that the equipment can load and unload multiple shafts at the same time.
