Description
Technical field
The invention belongs to machinery manufacturing technology field, it is related to a kind of positioning and clamping device, it is more particularly to a kind of to be used for case
The aligning positioning in internal hole and the application method of clamping device and the device.
Background technology
In machinery industry, box parts are usually as fundamental parts when assembling, axle, bearing, gear, end cap, set etc.
Component assembly makes each parts keep correct mutual alignment relation in casing.Therefore, the machining accuracy pair of box parts
Service life, performance and the precision of machine have important influence.Box parts are generally casting, structure and complex-shaped, rigidity
Poor, working position is more, difficulty is big, therefore box parts need to use special fixture when being processed on Digit Control Machine Tool mostly.
How box parts are quickly and correctly positioned on fixture is to ensure casing class part processing precision, improve processing efficiency
Key.Therefore in machinery industry, it is necessary to which a kind of can be according to the positioning of the endoporus automatic aligning of casing and the device clamped, to incite somebody to action
Casing is positioned and is fixed on fixture, to complete the processing of casing.
The content of the invention
Present invention aim to address positioning precision of the box parts in the prior art on fixture is low；Casing is easily pressed from both sides
Tight device is blocked；Positioning and clamping efficiency are low；Clamping device part is difficult to change, the problem of cost is higher there is provided one kind it is convenient,
Efficiently the aligning that casing endoporus automatic aligning is positioned and is clamped on fixture is positioned and clamping device.
The purpose of the present invention is achieved through the following technical solutions:
A kind of aligning positioning and clamping device for casing endoporus, the device includes base, clamp body, stud and handle
Hand；Wherein, stud is located in the screwed hole of base top, stud bottom connection big steel ball；It is uniformly distributed on base external cylindrical surface
