Abstract

The utility model relates to a quick clamping positioner of gear belongs to product processing technology field. This positioner is divided into two parts: 3 positioning blocks, 3 adapter seats and locking screws; the positioning surface of one end of the positioning block is matched with the groove of the adapter and fixed through a locking screw, and the other end of the positioning block is provided with a positioning rod matched with a pitch circle of the part. The positioning device utilizes the chuck of the machine tool to provide clamping force, directly acts on the pitch circle of the part, quickly and reliably clamps the part, enables the disc part and the planetary gear part to directly and reliably clamp through the positioning device, does not need to additionally align the pitch circle during machining, and saves a large amount of labor cost and production period.

Description

Quick clamping and positioning device for gear
Technical Field
The utility model relates to a quick clamping positioner of gear belongs to product processing technology field.
Background
For disk parts and planetary gear parts, clamping in a magnetic sucker mode is needed when an inner hole is ground; meanwhile, in order to ensure the depth and uniformity of the carburized layer of the tooth part, the pitch circle of the part needs to be aligned during processing, the parts are different in state after heat treatment, the part pitch circle needs to be manually aligned and then processed, the efficiency is low, the labor intensity is high, and scientific research and production tasks are severely restricted.
Disclosure of Invention
The utility model aims at providing a gear rapid clamping and positioning device which can be directly connected with a machine tool chuck interface and directly center the pitch circle of a part; the positioning block can be quickly replaced aiming at different modulus parts, so that the machining efficiency can be effectively improved, and the machining cost is reduced.
The utility model discloses a concrete technical scheme does: the positioning device comprises 3 positioning blocks, 3 adapter seats and locking screws; each positioning block, the adapter and the locking screw form a group, the three groups are formed, the positioning surface at one end of each positioning block is matched with one adapter groove and is fixed through the locking screw, and the other end of each positioning block is provided with a positioning rod matched with a part pitch circle; the lower end of the positioning rod of the positioning block is provided with a step or an arc adapter; two threaded holes are arranged on two sides or one side of the groove of the adapter, and the threaded holes are equidistant from the center of the adapter.
The positioning device provides clamping force with the chuck of the machine tool itself.
The clamping force directly acts on the pitch circle of the part to clamp the part quickly and reliably.
The diameter of the positioning rod at the top end of the positioning block can be changed according to different modulus of the part.
The lower end of the positioning rod of the positioning block is provided with a step or an arc for switching.
The bottom end of the adapter is connected with the machine tool chuck.
The utility model has the advantages that: the positioning device utilizes the chuck of the machine tool to provide clamping force, directly acts on the pitch circle of the part, quickly and reliably clamps the part, enables the disc part and the planetary gear part to directly and reliably clamp through the positioning device, does not need to additionally align the pitch circle during machining, and saves a large amount of labor cost and production period.

Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1-4, the positioning device for rapidly clamping and positioning the gear is divided into two parts: 3 positioning blocks, 3 adapter seats and locking screws; the positioning device comprises 3 positioning blocks, 3 adapter seats and locking screws; each positioning block, the adapter and the locking screw are in a group of three groups, the positioning surface at one end of each positioning block is matched with one adapter groove and is fixed by the locking screw, and the other end of each positioning block is provided with a positioning rod matched with a part pitch circle; and (5) clamping the pitch circle of the part during processing. The lower end of the positioning rod of the positioning block is provided with a step or an arc adapter; two threaded holes are arranged on two sides or one side of the groove of the adapter, and the threaded holes are equidistant from the center of the adapter.
The lower end of the positioning rod of the positioning block is provided with a step or arc switching to prevent the interference with the tooth top of a part during processing.
Two threaded holes are formed in two sides or one side of the groove of the adapter, and the threaded holes are equidistant from the center of the adapter.
The diameter of the positioning rod at the top end of the positioning block can be changed according to different modulus of parts, and the bottom end of the adapter is connected with the chuck of the machine tool.
The technical scheme of the utility model is not limited to the internal grinding machine, other machine tools with clamping discs, no matter mechanical clamping discs or hydraulic clamping discs, the positioning device in the form can be adopted for quick positioning; the invention is equally applicable to helical gears.
