Detailed Description

The present utility model will be further described in the following to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present utility model easy to understand.

As shown in fig. 1 to 3, a cylinder housing part plane machining device comprises a tool base 1 for placing a cylinder housing 2, a spherical boss 8 arranged on the tool base 1 and assembled with the cylinder housing 2 through a pin, an L-shaped positioning block 3 arranged on the tool base 1 and manually rotating the right end of the cylinder housing 2 to be in contact with the right end of the cylinder housing 2, and a cylinder 4 arranged on the side end surface of the tool base 1 and used for propping against the L-shaped positioning block 3 and the cylinder housing 2.

The tool base 1 is provided with a V-shaped block positioning 11 for automatically aligning the central axis of the outer circle.

The V-shaped block positioning 11 is a sunken type sinking positioning, so that the lower end of the actuator cylinder shell 2 is perfectly matched with the tool base 1.

The axial positions of the central hole of the tool base 1 and the actuating cylinder shell 2 are kept consistent.

The spherical boss 8 cooperates in a point contact mode when clamping with the cylinder 4, and compared with a surface contact mode, the spherical boss is better in protecting parts, and deformation of the parts caused by clamping after reference deviation in the machining process is avoided.

The semi-automatic positioning and clamping fixture for machining the surface and the upper surface hole of the part of the actuator cylinder shell 2 is characterized in that the central axis of the outer circle is automatically aligned by utilizing the principle of positioning 11 of a V-shaped block on the fixture base 1, and then the positioning surface is aligned by the L-shaped positioning block 3, so that the position requirements of the machined surface and the central hole axis are ensured, and finally pneumatic clamping is realized, wherein the spherical surface of the spherical boss 8 is utilized to be fixed with a clamping mechanism in a point contact manner, so that the position requirements of the part on the fixture can be ensured, the part is prevented from directly contacting with a clamping device, and the machined surface of the part is damaged.

The L-shaped positioning block 3 is provided with a cover 6 which fixes the L-shaped positioning block 3 on the tool base 1 through a plurality of groups of bolts 5.

The utility model provides a general semi-automatic positioning and clamping tool for a cylinder shell belt processing surface part, which solves the problems of secondary damage to the part and time and labor waste in clamping caused by the traditional clamping mode while ensuring the position requirement.

The cover 6 is internally provided with a spring 9 which is matched with the L-shaped positioning block 3 and used for controlling the stroke of the L-shaped positioning block 3.

The cover 6 is provided with a travel locating pin 7 for controlling the limit travel of the L-shaped locating block 3.

When no part is clamped, the L-shaped positioning block 3 is positioned at the maximum stroke under the action of the spring 9, wherein the limit position is controlled by the stroke positioning pin 7, so that the stroke cannot be exceeded.

When the parts are clamped, the L-shaped positioning block 3 is contracted in stroke, the spring 9 is in a compressed state, and the parts are slightly rotated manually so as to meet the requirement of no clearance, and the position accuracy is ensured.
