Embodiment approach 1

[0012] A flexible finishing device for hole surface, comprising a whetstone rod 1, a bracket 2, a core frame 3, a cover plate 4 and a top sleeve 5, the bracket 2, the core frame 3 and the cover plate 4 are connected together by bolts, and the The root of the whetstone rod 1 is covered with a top sleeve 5, which is placed in the radial hole on the bracket, and can expand and contract along the radial hole.

[0013] Put the whole device into the inside of the machined hole, and start the motor at the same time, and the motor transmits the torque to the bracket 2 through the coupling. After the support 2 rotates and the rotational speed reaches a certain value, the whetstone rod 1 placed in the radial hole of the support 2 acts on the surface of the hole with a certain pressure to realize the finishing process of the surface of the hole. If the automatic feeding device is added, the finishing process of the entire hole surface can be realized.

[0014] The outer diameter and inn...

Embodiment approach 2

[0021] A hole surface flexible finishing device, the outer diameter of the bracket 2 is Φ160mm, the inner diameter of the bracket 2 is Φ120mm, the outer diameter of the mandrel 3 is Φ80mm, and the number of meshes of the whetstone rod 1 is 320. The specific steps are:

[0022] 1. Place the hole surface finishing device in the hole to be processed.

[0023] 2. Turn on the power, turn on the governor, and set the speed value of bracket 2 to 500r / min through the governor.

[0024] 3. Start the flexible finishing device, and the bracket 2 starts to rotate and process the hole surface.

[0025] 4. After processing, take out the device.

[0026] The surface roughness value after testing and processing can reach Ra0.3μm.

Embodiment approach 3

[0028] A flexible finishing device for hole surface, the outer diameter of the bracket 2 is Φ160mm, the inner diameter is Φ120mm, the outer diameter of the mandrel 3 is Φ80mm, and the mesh number of the whetstone rod 1 is 320. The specific steps are as follows:

[0029] 1. Place the hole surface finishing device in the hole to be processed.

[0030] 2. Turn on the power, turn on the governor, and set the speed value of bracket 2 to 800r / min through the governor.

[0031] 3. Start the flexible finishing device, and the bracket 2 starts to rotate and process the hole surface.

[0032] 4. After processing, take out the device.

[0033] The surface roughness value after testing and processing can reach Ra0.25μm.

Abstract

A hole surface flexible finishing device, which belongs to the technical field of mechanical parts surface finishing, is characterized in that it uses the centrifugal principle to control processing parameters externally in real time to achieve flexible, automatic and controllable processing, and can automatically A device for processing the surface of holes such as curved holes, stepped holes, and special-shaped holes. The processing device adjusts the force between the oilstone rod and the hole surface by externally controlling the motor speed, so as to realize constant pressure processing and ensure the uniformity of processing; flexible The skinning head has a certain degree of flexibility and can pass through curved holes and special-shaped holes of a certain size. The surface finishing device has a simple structure, a small footprint, convenient control, and easy automation.

Description

technical field [0001] The invention relates to a hole surface flexible finishing processing device, which belongs to the technical field of surface finishing processing of mechanical parts, and particularly relates to the finishing processing technology of non-free abrasive tools on the surface of holes, especially the hole surfaces of curved holes, stepped holes, deep holes, special-shaped holes, etc. finishing process. Background technique [0002] The surface quality of parts plays a crucial role in the performance and life of mechanical products, and some surface defects are the direct cause of abnormal machine operation and even paralysis. In the surface finishing of parts, the surface finishing of holes is relatively difficult, especially the surface of holes such as stepped holes, curved holes, and special-shaped holes. Therefore, how to effectively solve the problem of finishing the hole surface is of great significance for improving the quality of parts and produc...
