Description
Technical field
The utility model is related to screw compressor field, more particularly to a kind of scroll compression machine crankshaft bent neck clamping work
Dress.
Background technology
The clamping method of the bent neck of existing scroll compression machine crankshaft is：1st, adjustment scroll chuck and the machine tool chief axis centre of gyration
Eccentric throw to needing size；2nd, workpiece is reset, because the refitting precision of scroll chuck is 0.1mm, not reaching workpiece accuracy will
Ask, it is necessary to according to the eccentric size of the eccentric throw error transfer factor scroll chuck of processing workpiece；The shortcoming of this clamping method：1st, due to
The refitting precision of scroll chuck is ± 0.05mm, does not reach workpiece accuracy requirement, and each clamping is needed according to the inclined of processing workpiece
Eccentric size of the heart away from error transfer factor scroll chuck；2nd, processing efficiency is low, and such precision bent axle can not be produced in batches.
Utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provide a kind of simple in construction, behaviour
Make the bent neck clamping tooling of convenient, practical scroll compression machine crankshaft.
The utility model is realized in the following way：
A kind of bent neck clamping tooling of scroll compression machine crankshaft, it is characterised in that：Including disk fixed seat 1, positioning sleeve 2,
The centre of the disk fixed seat 1 offers mounting hole 11；By being interval with some clamping fixture blocks in the disk fixed seat 1
12；Some clamping fixture blocks 12 are centered on the center of circle of mounting hole 11, by ring type array way in disk fixed seat 1；It is described
Radial direction of the clamping fixture block 12 along disk fixed seat 1 is slided and fixed；The positioning sleeve 2 is provided with to match with mounting hole 11
Lower stationary cylinder 21；The upper surface of the lower stationary cylinder 21, which is upwardly extended, is formed with stationary cylinder 22；It is described
Provided with the clamping hole 23 matched with bent axle 4 in positioning sleeve 2；Fixed cylinder 22 is provided with screw hole 24；The spiral shell
Silk hole 24 is connected with clamping hole 23；The screw hole 24 is provided with holding screw 3.
Further, the race diameter of fixed cylinder 22 is more than the race diameter of lower stationary cylinder 21.
Further, the end of the holding screw 3 is welded with the layers of copper matched with bent axle 4.
The beneficial effects of the utility model are：Simple in construction, easy to operate, practical, efficiency high, clamping effect is good.
Brief description of the drawings

Fig. 2 the utility model structure decomposition figures.
Embodiment
In conjunction with accompanying drawing, the utility model embodiment is described in detail：
As shown in Figure 1 and Figure 2, the bent neck clamping tooling of a kind of scroll compression machine crankshaft, including disk fixed seat 1, positioning sleeve
2, the centre of disk fixed seat 1 offers mounting hole 11；By being interval with some clamping fixture blocks 12 in disk fixed seat 1；It is some
Clamping fixture block 12 is centered on the center of circle of mounting hole 11, by ring type array way in disk fixed seat 1；The edge of clamping fixture block 12
The radial direction of disk fixed seat 1 is slided and fixed；Positioning sleeve 2 is provided with the lower stationary cylinder matched with mounting hole 11
21；The upper surface of lower stationary cylinder 21, which is upwardly extended, is formed with stationary cylinder 22；It is provided with and the phase of bent axle 4 in positioning sleeve 2
The clamping hole 23 of matching；Upper stationary cylinder 22 is provided with screw hole 24；Screw hole 24 is connected with clamping hole 23；Screw hole 24
It is provided with holding screw 3.
The race diameter of stationary cylinder 22 is more than the race diameter of lower stationary cylinder 21 on the utility model, convenient solid
Fixed and clamping.
The end of the utility model holding screw 3 is welded with the layers of copper matched with bent axle 4, in order to avoid the surface quilt of bent axle 4
Scratch.
The cylindrical gap of the utility model clamping hole 23 and the position point of bent axle 4 is 0.01mm.
During operation, disk fixed seat 1 is fixed on the machine tool chief axis centre of gyration, positioning sleeve 2 passes through some clamping fixture blocks
12 are clamped fixation, then by the clamping of holding screw 3 to positioning sleeve 2, and screw is upward to facilitate fixed crankshaft 4；By bent axle 4
The debris of surface and the endoporus of positioning sleeve 2 is cleaned out；Bent axle 4 is put into positioning sleeve 2, the shaft shoulder is leaned against on the end face of positioning sleeve 2；
Lock holding screw 3, the eccentric throw of adjustment clamping fixture block 12 and the machine tool chief axis centre of gyration is to needing size；Bent axle 4 is reset, then
The bent axle 4 of secondary processing is with the eccentric throw error of bent axle 4 of preceding time processing in 0.006mm, and error is small.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical fields, are similarly included in scope of patent protection of the present utility model.
