Detailed Description
The invention will be further described with reference to the following drawings and specific embodiments:
the utility model provides a be used for handling material machine gripping apparatus slip sleeve nut assembly and disassembly tools, includes handle 1, support ring 2, locating pin 3.
The handle 1 is a cylinder with one end being a curved surface, and one end of the curved surface is fixedly connected with the cambered surface at the center of the support ring 2.
The support ring 2 is a semicircular ring, the outer side of the cambered surface at the center of the semicircular ring is fixedly connected with the handle 1, and two ends of the central line of the end surface of the semicircular ring are fixedly connected with the positioning pins 3 respectively.
The locating pin 3 is a cylinder, one end of the locating pin 3 is fixedly connected with one surface of the support ring, and the other end of the locating pin is arranged in any two locating holes of the sliding sleeve nut at a distance of 120 degrees.
The clearance between the positioning pin 3 and the positioning hole is less than 0.25mm, and the external rotating force is transmitted.
The length of the positioning pin 3 is 10mm, the length is longer than the depth of the positioning hole, and the positioning pin can be taken out when the positioning pin is broken.
