Embodiment Construction
[0021] Below in conjunction with accompanying drawing this patent is further described:
[0022] Such as figure 1 , figure 2 , image 3 The bottom connection method of the base 12 shown is consistent with the connection method of the middle chamber of the valve body. The upper part uses locking screws 14 to connect the connecting brackets 6 on both sides. , the other side is a keyway structure, the purpose is to facilitate the driving connection) and the eccentric cam 4 is connected by key 15 for transmission, the adjustment rod 7 and the guide rod 10 are connected by threads, the adjustment rod 7 and the eccentric cam 4 are in high pair contact, and the guide rod 10 and base 12 increase reciprocating spring 11 and all are installed in support 6 inboards. The lower end of the guide rod 10 is threaded to connect the slope bottom plate 16, and at the same time, ball joints are used to connect the grinding plate 18 on both sides of the slope bottom plate 16, and the limit scr...

The invention belongs to grinding tools, and particularly relates to a small-diameter top-assembling ball valve body grinding tool. The small-diameter top-assembling ball valve body grinding tool includes a base, a bracket is fixed to the base, a transmission shaft assembly is arranged on the bracket, an eccentric cam is connected to the transmission shaft assembly in a sleeving mode, an adjustment rod is arranged below the eccentric cam, and the adjustment rod can be driven by the eccentric cam to perform reciprocating motion. A guide sleeve is arranged below the adjustment rod, and a guide rod is arranged in the guide sleeve. A reciprocating spring is arranged between the guide rod and the base, and a top-assembling ball valve body is arranged at the tail end of the guide rod. The small-diameter top-assembling ball valve body grinding tool has the effects that the structure is ingenious and operation is easy, the fit performance is good in the tool grinding process, the service lifeof the tool is long, and the work intensity of operators during use is reduced.
Description
technical field [0001] The invention belongs to a grinding tool, in particular to a grinding tool for a small-diameter top-mounted ball valve body. Background technique [0002] Small-bore top-entry valve body parts are symmetrically distributed in a small space and compact valve cavity with a certain slope due to the smoothness of the sealing surface as high as Ra0.2. The traditional grinding method cannot be used to grind the sealing surface. [0003] In view of the above situation, how to use the existing valve chamber with compact structure and limited space to carry out research on sealing surface grinding has become the primary problem facing the manufacture of small diameter top entry ball valve body. Contents of the invention [0004] Aiming at the defects of the prior art, the invention provides a small-diameter top-mounted ball valve body grinding tool. [0005] The technical solution of the present invention is: a small-diameter top-mounted ball valve body grin...
