Description

A kind of pressing cover tools ensureing concentricity
Technical field
The utility model belongs to transporation by plane technology, relates to a kind of device lining being accurately assembled to frock.
Background technology
Due to lining, drill bushing be fixture, the part commonly used very much of type frame, and its precision directly affects the positioning precision of whole fixture, type frame, and the effect of drill bushing is more obvious in drill jig, and its precision directly affects the precision of product.So the positional precision of guarantee lining, drill bushing is the most important thing.First the precision difference machining accuracy of lining and positioning precision two aspects of gland, present working ability can ensure the internal-and external diameter precision of lining, so machining accuracy is no problem, can meet use needs.But after lining machines, assembler during gland, cannot ensure concentricity in clamp and drill jig, thus just cannot ensure positioning precision, so aobvious particularly important of the accuracy of gland.A kind of novel pressing cover tools of exigence, ensures concentricity, improves the positioning precision of fixture, type frame, reduce repair rate, percent defective.
The content of invention
The object of invention
The utility model is to provide a kind of device lining being accurately assembled to frock, ensures hole and the concentricity of lining and the accuracy of position.
The technical scheme of invention
Ensure a pressing cover tools for concentricity, this pressing cover tools is made up of fastening body 1, handle 2, base 3.The tolerance that is fixedly slidably matched is adopted to be connected by fastening body 1 external diameter and bushing inner diameter, base 3 is positioned over below hole, and by the screw rod in fastening body 1 and base 3 screwed hole center centering, lining is made to be positioned at center, hole, then twisted by screw thread and all spare to power in lining, lining is pressed in locating hole accurately, thus ensure that concentricity, avoid overproof.
5. the effect of invention
Can accurately by lining centering press-in hole, easy to operate, the off-gage phenomenon after avoiding tool locating piece bores to be pressed into lining, thus improve positioning precision and the quality of frock.Simultaneously laborsaving, and efficiently, convenient and swift.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below the utility model is described in further details.Pressing cover tools (see Fig. 1) by 1, fastening body 2, handle 3, base form.The tolerance that is fixedly slidably matched is adopted to be connected by fastening body 1 external diameter and bushing inner diameter, fastening body 1 end head has screw thread, be connected with base 3 screwed hole by fastening body 1 screw thread, screw thread lifting is relied on to make lining evenly be pressed into locating hole, in use base 3 is positioned over below prepackage bush hole, and by the screw rod in fastening body 1 and base 3 screwed hole center centering, lining is made to be positioned at center, hole, then twisted by screw thread and all spare to power in lining, lining is pressed in locating hole accurately, thus ensure that concentricity, avoid overproof.
Using method of the present utility model is: when applying this instrument, first base 3 to be put into below hole and centering is had good positioning, secondly lining is loaded in fastening body 1, close tolerance by fastening body external diameter and lining cunning to be connected, then centering Hao Kong center fixing, lining centering is made to pre-install center, hole, power is all spared in lining with base 3 screw thread finally by turning fastening body 1, lining uniform stressed is pressed into center, hole, make not by the hard power in left and right, finally fastening body 1 is extracted from lining, thus ensure that concentricity.

Claims (1)

1. one kind ensures the pressing cover tools of concentricity, this pressing cover tools is made up of fastening body (1), handle (2), base (3), the tolerance that is fixedly slidably matched is adopted to be connected by fastening body (1) external diameter and bushing inner diameter, base (3) is positioned over below hole, and by the screw rod in fastening body (1) and base (3) screwed hole center centering, lining is made to be positioned at center, hole, then twisted by screw thread and all spare to power in lining, lining is pressed in locating hole accurately.
