Description
Technical field
The utility model is related to the auxiliary tools in auto parts machinery assembling field, especially a kind of to be assembled for auto parts machinery
Auxiliary device.
Background technology
Existing piston of automobile and small axis are assembled, which belongs to high-precision part, processing essence
Degree is very high.The one end for clamping small axis usually using devices such as bench vice hydraulic cylinders in assembly at present, then assembles with piston again.It is existing
This method of clamping having is easy that small shaft workpieces is made to deform, attenuates, surface generation cut, these can all lead to workpiece report
It is useless, increase raw material usage amount, enterprise's production cost is caused to increase, reduces the market competitiveness.
Utility model content
The purpose of this utility model is that in place of making up the deficiencies in the prior art, provide a kind of reasonable design, using it is easy,
It is avoided that the impaired auxiliary device for auto parts machinery assembling of workpiece.
The purpose of this utility model is realized by following technological means：
A kind of auxiliary device for auto parts machinery assembling, it is characterised in that：Including bottom plate, riser, cam spanner, fixation
Set, expansion sleeve and end cap install a riser on bottom plate, and a cam spanner is installed at the back side of the riser, the cam spanner
Pull rod passes through riser and connects an expansion sleeve, and one small axis plug-in opening is coaxially made in the expansion sleeve, and expansion sleeve outside is same
Axle sleeve fills a fixing sleeve, which is mounted on the front of riser, and the contact surface of the fixing sleeve and expansion sleeve is inclined-plane, solid
Surely the front end outer side covered is co-axially mounted an end cap, and a through-hole being coaxially disposed with small axis plug-in opening is made on the end cap.
Moreover, front end outer side of the end cap screw thread engagement mounted on fixing sleeve.
The advantages of the utility model and good effect are：
1, the present apparatus is mainly made of bottom plate, riser, cam spanner, fixing sleeve, expansion sleeve and end cap, expansion sleeve and fixation
Set is contact of incline plane, and expansion sleeve can be moved with cam spanner, realize the locking of small axis, and the locking mode is simple and convenient, and
Speed is fast, can improve working efficiency.
2, the present apparatus uses tensioner cover locking, can avoid small shaft distortion or surface tear, and can in assembling process
To be set with rubber washer between end cap and piston, piston face is avoided to be scratched.Above-mentioned design can guarantee the quality of product, drop
Low rejection rate, saves raw material input, and economic cost is saved for enterprise.
3, the present apparatus is simple in structure, manufacture is easy, at low cost, and staff's manufacture capable of automatic assembling will not increase production
Cost.
4, the utility model, which is a kind of reasonable design, simple in structure, manufacture is easy, easy to use, highly practical is used for
The auxiliary device of auto parts machinery assembling, the present apparatus are designed exclusively for high-precision piston and the assembly of small axis, this dress is used
It sets and is not only able to prevent workpiece surface from deforming, workpiece quality meets the requirements of the customers after ensureing assembly, and can also reduce workpiece
Assembly difficulty, the operating process for simplifying staff, the assembling speed for improving workpiece.

Specific implementation mode
Embodiment of the utility model will be described in detail below with reference to the attached drawings；It should be noted that the present embodiment is narrative
, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of auxiliary device for auto parts machinery assembling, including bottom plate 5, riser 2, cam spanner 1, fixing sleeve 3, tensioner
7 and end cap 4 are covered, a riser is installed on bottom plate, a cam spanner, the pull rod 6 of the cam spanner are installed in the back side of the riser
Horizontally disposed, which passes through riser and connects an expansion sleeve, coaxially makes one small axis plug-in opening in the expansion sleeve, this rises
One fixing sleeve of fixed outside coaxial package, the fixing sleeve are mounted on the front of riser, the contact surface of the fixing sleeve and expansion sleeve
For inclined-plane.
It is co-axially mounted an end cap in the front end outer side of fixing sleeve, fixing sleeve is connect with end cap using screw thread engagement system.
A through-hole 8 being coaxially disposed with small axis plug-in opening is made on the end cap.
The application method of the utility model is：
Small axis is penetrated in small axis plug-in opening first, drives expansion sleeve to move using cam spanner, it is made to lock small axis.So
Piston 9 and nut are sleeved on small axis afterwards, piston and small axis can finally be fitted together using torque spanner.It is assembling
In the process, in order to avoid piston side wall is contacted with end cap and is damaged, can between end cap and piston coaxial package rubber washer.
