Description
Technical field
The invention belongs to Workpiece clamping device field.
Background technology
When drilling gear end face at present, more using coupling gear fixed tooth shape, it is impossible to which fixture is detected in itself, can only
According to being adjusted to fixture again after the product actual measurement for processing, fixed gear is positioned using welding manner again after adjusting,
The reason for fixture after welding is because of internal stress causes deformation, and fixture is very unstable using process, and the debugging clamper time is long, product matter
Amount is unstable, and qualification rate is relatively low.
Authorization Notice No. is the patent document of CN102275080B, discloses a kind of device, including base and is arranged on
Fixture combination on the base, the fixture combination include fulcrum bearing, locating piece, resilient sleeve, pull bar, alignment pin, briquetting with
And location key seat, the upper horizontal of the fulcrum bearing is shelved with gear, and the locating piece is stuck in the keyway of the gear, described
The spherical head of alignment pin is horizontally inserted between two teeth of the gear to prevent gear from rotating, and the upper end of the resilient sleeve is through
In the endoporus of the gear, tapered tail of the pull bar from the top down through resilient sleeve and pull bar struts the upper end of resilient sleeve
Positioned with the zero-clearance for realizing gear and resilient sleeve, the lower end of the pull bar is stretched into the base, and the briquetting is pressed in the tooth
The top of wheel.The fixture that the technical scheme solves welding is very unstable using process, and the debugging clamper time is long, and product quality is not
Stabilization, qualification rate is relatively low.But the technical scheme makes the method that resilient sleeve deforms come fixed gear using pull bar, because in pull bar
There is gap between portion and resilient sleeve, when pull bar is inserted, if excessive to the active force of resilient sleeve, where the above-mentioned gap of resilient sleeve
Part can fit with pull bar, cause resilient sleeve to disperse the lateral pressure of inner ring gear, not reach fixed effect.
The content of the invention
When the fixed gear of prior art presence is solved it is an object of the invention to provide a device, retaining element group pair
