Problems solved by technology

At present, most of the fixtures used adopt the positioning method of two sides and one pin. The design of the fixture is relatively complicated, and the number of parts is large. In order to match the palms of different specifications, it is necessary to replace the V-shaped block and the pressing block of different specifications. The design of the V-shaped block is complicated, and The compression head on the compression block is easy to break, causing potential safety hazards. In addition, the mold change operation takes a long time, especially because the product processing and debugging are difficult, requiring operators to have rich experience

Abstract

The invention discloses a fixing device for processing tooth palm journals. The fixing device comprises a chuck, a positioning plate, clamping jaws, a positioning block, a pressing arm seat and a pressing arm, wherein the positioning plate is arranged on the chuck; the clamping claws moving towards the center are arranged on two sides of the positioning plate; clamping jaw positioning pins are arranged on the opposite side faces of the clamping jaws; a positioning block at one sides of jaw side elevations is arranged on the center line of the positioning plate; a radial positioning pin is arranged on the positioning block; the pressing arm seat is arranged on one side of the positioning block; the pressing arm extending towards the positioning block is arranged at the top end of the pressing arm base; the pressing arm is hinged to the top end of the pressing arm seat, and the pressing arm rotates around the pressing arm seat; and a locking structure is arranged on the pressing arm to fix the pressing arm and the pressing arm seat. According to the fixing device, the structural design is reasonable, the machining difficulty is reduced, by means of the self-centering function of thechuck, the repeated positioning precision of a workpiece is high, and the production quality can be improved; the operation is simple, the replacement is quick, and the debugging time is shortened; the accessory can be replaced, and the device is suitable for products of different sizes; and the product processing and debugging difficulty is low, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a fixture for machining palm journals. Background technique [0002] The palm is the main part of the roller cone bit. Due to its extremely irregular shape, it is necessary to use a special fixture to fix it to the processing equipment when machining the journal. At present, most of the fixtures used use the positioning method of two sides and one pin. The design of the fixture is relatively complicated, and the number of parts is large. In order to match the palms of different specifications, it is necessary to replace the V-shaped block and the pressing block of different specifications. The design of the V-shaped block is complicated, and The pressing head on the pressing block is easy to break, causing potential safety hazards. In addition, the mold changing operation takes a long time, especially because the product processing and debugging are more difficult, requiring operators to have rich experience.
