Description
Technical Field
The utility model relates to a machining equipment technical field, concretely relates to tooth processing locking frock is attacked in multiple gear combination.
Background
In the modern machining field, the gear machining production process is gradually and finely accelerated, a technical scheme of group synchronous machining is generally adopted for accelerating the gear tapping efficiency, necessary clamping tools are lacked on the existing parallel clamping machining scheme, namely, for processing a plurality of parallel grouped gears, accurate positioning, internal stress balance machining and firm clamping need to be kept, and therefore the clamping tools need to be specially designed to assist the gear tapping production efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose: to the technical demand among the background art, we design a tooth processing locking frock is attacked in multi-gear combination, can wait to attack the tooth gear with the accurate series connection of gear centre bore with the polylith to assemble the clamp shaft through the position sleeve and splice polylith gear with the correction gear machining gesture, get rid of the processing internal stress that attacks the tooth process and produce to the gear, the clamping is swift high-efficient, and the location is accurate, simple and practical.
The technical scheme adopted for solving the problems is as follows:
a multi-gear combined tapping, processing and locking tool comprises a clamping shaft, a positioning sleeve and a locking nut.
The clamping shaft comprises a clamping part, a shaft shoulder and a positioning part which are integrally arranged, the clamping part is fixedly connected with a three-jaw chuck of a machine tool and is tightly attached to the shaft shoulder, the positioning part is in shaft hole sleeve positioning with a central hole of a gear to be tapped in a transition fit mode, rectangular grooves are uniformly and annularly arrayed on the periphery of the positioning part and are used for matching with positioning keys arranged on the inner wall of the central hole of the positioning sleeve and accurately clamping the gear, a thread section is further arranged at the front end of the positioning part and is used for matching with a locking nut to lock the positioning sleeve,
the positioning sleeve comprises a positioning plate and positioning keys, the positioning keys are integrally arranged on the inner wall of the central hole of the positioning plate in an annular array and correspond to the rectangular grooves in one-to-one mode, the positioning keys are in clearance fit with the side walls of the rectangular grooves and are in transition fit with the bottoms of the rectangular grooves,
the locking nut is in threaded connection with the threaded section, and a gasket is further sleeved on the contact surface of the locking nut and the positioning plate of the positioning sleeve.
Furthermore, the height of the positioning key is smaller than the depth of the rectangular groove, so that the positioning key does not touch the central hole of the gear penetrating and sleeved on the positioning part when being matched with the rectangular groove in a positioning mode.
Furthermore, the rectangular groove of the positioning part can also correspond to a key groove formed in the central hole of the gear, and the positioning key with a heightened design is in clearance fit with the rectangular groove to limit the rotational freedom degree of the gear.
The utility model has the advantages that:
this tooth processing locking frock is attacked in combination of multiple gears can treat the polylith and attack the tooth gear and establish ties with the gear centre bore accuracy to attach the clamping shaft through the position sleeve cooperation and splice polylith gear in order to correct the gear machining gesture, get rid of the internal stress of processing that attacks the tooth process and produce to the gear, the clamping is swift high-efficient, fixes a position accurately, simple and practical.
