Abstract
A kind of machined part, particularly a kind of fixture for being used to clamp plastic part, including base, it is characterised in that：The base top is provided with clamping plate, the clamping plate bottom is connected by connecting portion with base, the clamping plate has several upward projections vertically, and base top position corresponding with above-mentioned projection has groove, the groove and the hole that male cooperation Formation cross-section is in " O " shape.Distinctive feature of the present utility model is:Plastic part clamping is processed again on the fixture, machining accuracy is high, and error is small.
Description
Technical field
A kind of machined part is the utility model is related to, particularly a kind of fixture for being used to clamp plastic part.
Background technology
In field of machining, plastic part is a kind of great part of difficulty of processing, because working of plastics has resilience,
Run into external force easily to deform upon, clamping error and assembling indifference easily occur during processing, therefore prior art is in processing plastic part
When error it is larger.
Utility model content
The purpose of this utility model is to provide a kind of fixture, plastic part clamping is processed again on the fixture,
Machining accuracy is high, and error is small.
Realizing the technical scheme of the utility model purpose is：A kind of fixture for being used to clamp plastic part, including base, its
It is characterised by：The base top is provided with clamping plate, and the clamping plate bottom is connected by connecting portion with base, and the clamping plate has vertically
There are several upward projections, base top position corresponding with above-mentioned projection has groove, the groove and male cooperation shape
It is in the hole of " O " shape into section.
And the bottom of institute's groove has positioning key.
And there is gap between the clamping plate and base, there is adjusting gasket to be placed in the gap.
And the raised top is provided with through hole, has fastener to be arranged in the through hole.
And the both ends of the clamping plate have positioning hole, there is bolt through the positioning hole and be connected with whorl of base.
The utility model has the advantage of:1. working of plastics clamping on fixture after pass through the fastenings at top, bottom
Positioning key and the triple fixations of clamping plate, it will not be subjected to displacement during processing, machining accuracy is high.2. regulation is set between clamping plate and base
Pad and the dynamics that clamping is controlled by bolt, clamping error is reduced, so as to improve the precision of processing.
Brief description of the drawings
Fig. 1 is a kind of structural representation for being used to clamp the fixture of plastic part.
Embodiment
Referring to Fig. 1, the utility model is described further below with reference to embodiment.
A kind of machined part, particularly a kind of fixture for being used to clamp plastic part, including base 1, its feature exist
In：The top of base 1 is provided with clamping plate 2, and the bottom of clamping plate 2 is connected by connecting portion 3 with base 1, and the clamping plate 2 has vertically
There are several upward projections 2.1, the top of base 1 has groove 1.1, the groove 1.1 with above-mentioned raised 2.1 corresponding position
The hole that section is in " O " shape is cooperatively formed with projection 2.1.
During work, plastic part to be processed is placed in groove 2.1 with raised 1.1 holes cooperatively formed, tightening projection
The fastener 5 at top, the bolts at two ends 7 by adjusting clamping plate 2 reach the purpose of regulation clamping dynamics.
Working of plastics clamping on fixture after by the 2 triple fixations of the fastenings 5 at top, the positioning key 4 of bottom and clamping plate,
It will not be subjected to displacement during processing, machining accuracy is high.
And the bottom of institute's groove 1.1 has positioning key 4.
The positioning key 4 of the bottom of groove 1.1 closes with the recesses in parts to be processed side wall, so as to realize the mesh of positioning
's.
Further technical scheme can have gap between the clamping plate 2 and base 1, have adjusting gasket 6 to be placed in this
In gap.
Adjusting gasket 6, which is placed in the gap, can control the clamping dynamics of clamping plate 2, avoid dynamics it is excessive cause it is to be processed
Part deforms upon, and effectively reduces clamping error so as to improve machining accuracy.
And raised 2.1 top is provided with through hole, there is fastener to set 5 in the through hole.
Fastener is tightened, gives parts to be processed one lower pressure from top, its stability in process can be improved.
Further technical scheme can also be that the both ends of the clamping plate 2 have positioning hole, have bolt 7 to pass through the positioning hole
And it is threadedly coupled with base 1.
By regulating bolt 7 so as to reach the purpose of regulation clamping dynamics, simple in construction, effect is good.
