The device constructed or detected, also referred to as fixture.The quality of fixture design has also just directly influenced the processing of processing object
Efficiency and machining accuracy propose higher want especially for the higher processing object of requirement on machining accuracy to the design of fixture
It asks.The prior art usually utilizes the cylindrical turning endoporus or increase work of scroll chuck folder thin-wall workpiece when processing thin-wall workpiece
Skill rib workpieces processing outer circle, but due to thin-wall workpiece (especially wall thickness 5mm thin-wall workpieces below) poor rigidity itself, processing
Process easily deforms, and particularly, there is following defect using the prior art as manufacturing process：1, the deformation of workpiece itself can influence
The dimensional accuracy and form accuracy of workpiece, the difficulty of cutting endoporus can be greatly increased by increasing technique rib；2, because workpiece wall is more thinly-sliced
Workpiece thermal deformation can be caused by cutting heat, and workpiece size is made to be difficult to control；3, it under the action of cutting force in particular back force, easily produces
Raw vibration, noise and deformation, directly affect the dimensional accuracy, geometric tolerance and surface roughness of workpiece.
Utility model content
The utility model is directed to deficiency in the prior art, and providing one kind can avoid thin-wall workpiece from deforming, and improve simultaneously
The vehicle clamper of processing efficiency.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals, a kind of vehicle clamper, packet
Chuck body is included, round positioning disk is provided on the processing end face of the chuck body, the circle positioning disk is provided centrally with
Spring block clamping device and the positioning device being located on around spring block clamping device, the spring block clamping device
Include the sliding block for end cap and being internally provided with the clamping seats of ladder-like cavity, and be arranged at step structure,
It is provided with wedge type block in the cavity of the clamping seats, the inner support spring being connect with end cap, position are equipped in the opening of wedge type block front end
The inclined-plane coordinated with sliding block is provided at the outer cornice of wedge type block both sides, the end of the wedge type block is provided with and spring block
The jacking block of clamping device cooperation, the positioning device includes positioning seat and the pull rod with briquetting, and positioning is provided in positioning seat
Structure, pull rod pass through positioning seat and the retaining spring in positioning seat to be connect with round positioning disk.
In said program, it is preferred that the chuck body is bolted to connection with round positioning disk.
In said program, it is preferred that the junction of the circle positioning disk and positioning seat is provided with spring catch, can keep
The stability of aperture size, and can quickly adjust the gap between positioning surface.
In said program, it is preferred that be provided with tension spring on the sliding block lug boss.
In said program, it is preferred that the location structure includes steel ball and steel ball positioning sleeve, is used for the positioning of pull rod.
Compared with prior art, the utility model has the advantages that：By inner support spring, wedge type block and sliding block
Between cooperation, by sliding block swelling workpiece to be processed, and positioning device is coordinated to position, passes through three-jaw card in the prior art
The mode of the outer circle of disk folder thin-wall workpiece clamps workpiece to be processed, avoids because workpiece wall is thin, clamps and occur from outer circle
Workpiece deflection it is serious, so as to avoid because workpiece deformation occur workpieces processing dimensional accuracy, geometric tolerance, Yi Jibiao
Not the problem of surface roughness does not reach requirement, meanwhile, clamping process is also more simple and efficient, improves working efficiency, reduction in the numbers of seconds.

Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
Referring to Fig. 1 to Fig. 5, vehicle clamper, including chuck body 1 are provided with circle on the processing end face of the chuck body 1
Positioning disk 2, which is characterized in that the circle positioning disk 2 is provided centrally with spring block clamping device and is located on spring cunning
Positioning device around block clamping device, the spring block clamping device include with end cap 31 and being internally provided with ladder
The clamping seats 32 of shape cavity, and the sliding block 33 that is arranged at step structure, are provided in the cavity of the clamping seats and carve
Shape block 34, the opening of 34 front end of wedge type block is interior to be equipped with the inner support spring 35 being connect with end cap, is located at the outer eaves of 34 both sides of wedge type block
The inclined-plane 341 coordinated with sliding block is provided at mouthful, the end of the wedge type block 34 is provided with to be coordinated with spring block clamping device
Jacking block 5, the positioning device includes positioning seat 41 and the pull rod 43 with briquetting 42, and location structure is provided in positioning seat,
