Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical production, and in particular relates to a positioning device for producing tractor cylinder covers. Background Art

[0002] When machining the cylinder head of an engine, the three outer surfaces of the cylinder head are usually milled out using a process platform, and then the three sides of the cylinder head are clamped using the plane structure of the machine tool to fix the position of the cylinder head before machining the cylinder head. However, when the three outer surfaces of the cylinder head are clamped using a plane, the cylinder head tends to move forward or backward during the machining process, so the positioning reliability is not strong, the positioning accuracy is not high, and the contact area between the cylinder head and the positioning device is large. When the cylinder head moves, friction occurs between the cylinder head and the plane, which easily leaves scratches on the outer surface of the cylinder head.

[0003] Application number "CN202222156954.4" records "a cylinder head installation positioning device, comprising: a positioning device, an extension device and a linkage plate, wherein the positioning device is provided in two, the two positioning devices are symmetrically arranged, the extension device is fixed between the two positioning devices, and the linkage plate is slidably connected to the two positioning devices."

[0004] The above patent is based on a cylinder head installation and positioning device, which can solve the problem that the cylinder head needs to be tightly fitted with the cylinder body during installation with high precision, and has certain requirements for installation accuracy. The existing installation method is that the manual installation accuracy is poor and it is easy to have poor sealing.

This device can install and position cylinder heads of different sizes and models.

[0005] The above patent can install and position cylinder heads of different sizes and models, but the device has not optimized the positioning accuracy during the overall processing. The structure of the device may not be perfect in terms of not causing scratches, resulting in low practicality of the device. Utility Model Content
