The utility model discloses set upright or straight and lead the coupling, guarantee that the correct assembly of coupling angle puts in place, compress tightly the assembly effect inside and outside reaching, greatly reduced quality risk and rework cost.
Description
Technical field
The utility model belongs to Automobile Assembling Technology frock technical field, and in particular to one kind is used for built-up crankshaft ventilation duct
The frock of joint.
Background technology
In prior art, the connecting tube assembly tooling of engine is telescopic independent percussion mode, easily causes to tap change
Shape, causes connecting tube to reveal, and body can be caused to scrap when serious, so that doing over again, manufacturing cost increases.
The content of the invention
In order to solve above-mentioned technical problem, the utility model devises a kind of for built-up crankshaft ventilation pipe joint
Frock, righting is carried out to pipe joint and is oriented to, so as to ensure connect pipe joint will not be struck partially, reach inside and outside compression fit
Effect, is so greatly lowered quality risk and rework cost.
In order to solve above-mentioned technical problem, the utility model employs below scheme：
A kind of frock of pipe joint of divulging information for built-up crankshaft, it is characterised in that：Including center-pole and screw thread positioning sleeve；Institute
State screw thread positioning sleeve to be arranged on the center-pole outer cylinder, and form an annular space therebetween to clamp simultaneously righting-oriented
Pipe joint.
Further, the center-pole is a stepped stem structure；One end head diameter of the center-pole is maximum, pars intermedia
Point it is machined with external thread structure the screw thread positioning sleeve is installed, other end diameter is minimum coordinating with the pipe joint.
Further, the center-pole is the stepped stem of hollow structure.
Further, be machined with female thread structure in one end set of the screw thread positioning sleeve, the screw thread positioning sleeve it is another
Clamping part is machined with the outer cylinder of end.
Further, the clamping part is processing a pair of planar on the screw thread positioning sleeve outer cylinder and vis-a-vis.
During work, first the center-pole and the screw thread positioning sleeve are assemblied together, then should by pipe joint insertion
Frock；Then by the frock centering installing port with the pipe joint, the center club head is tapped, the pipe joint is loaded
In installing port；Finally, the frock is extracted.
The frock for being used for built-up crankshaft ventilation pipe joint has the advantages that：
（1）The utility model designs ingenious, low manufacture cost；Simple structure, is easy to promote, compact conformation, uses, safeguards
It is convenient.
（2）The utility model inside increases the center-pole being oriented to, and outside increases screw thread positioning sleeve and escorted, during percussion pair
Pipe joint carries out righting and is oriented to, so as to ensure that pipe joint will not be struck partially, it is ensured that correctly assembling in place, reaches pipe joint angle
Inside and outside compression fit effect, greatly reduces quality risk and rework cost.

Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described further：
Fig. 1 to Fig. 4 shows a kind of frock of pipe joint of divulging information for built-up crankshaft, including center-pole 1 and screw thread positioning
Set 2.On the centrally disposed outer cylinder of bar 1 of screw thread positioning sleeve 2, and annular space receiving clamping pipe joint 3 is formed therebetween
To play a part of righting-oriented to pipe joint 3, as shown in Figure 3 and Figure 4.The structure of pipe joint 3 is as shown in Figure 5.
Center-pole 1 is a stepped stem structure, as shown in figure 1, one end head diameter of center-pole 1 is maximum, center-pole 1
Mid portion is machined with external thread structure 11 to install screw thread positioning sleeve 2, the other end diameter of center-pole 1 it is minimum with pipe joint
3 coordinate.In order to mitigate weight, center-pole 1 controls the stepped stem of structure in may be selected.
The structure of screw thread positioning sleeve 2 as shown in Fig. 2 be machined with female thread structure 22 in one end set of screw thread positioning sleeve 2 with
With the cooperating of external thread structure 11 of the mid portion of center-pole 1, relative processing on the other end outer cylinder of screw thread positioning sleeve 2
There is a pair of planar as clamping part 21 to facilitate operation.
During work, first center-pole 1 and screw thread positioning sleeve 2 are assemblied together, then pipe joint 3 is inserted into the frock；Then
By the frock centering installing port with pipe joint 3, the head of center-pole 1 is tapped, pipe joint 3 is fitted in installing port；Finally, extract
The frock.
The utility model inside increases the center-pole being oriented to, and outside increases screw thread positioning sleeve and escorted, and is striking frock
When hitting, righting is carried out to pipe joint and is oriented to, so as to ensure that pipe joint will not be struck partially, it is ensured that pipe joint angle is correctly assembled to
Position, reaches inside and outside compression fit effect, is so greatly lowered quality risk and rework cost.
In the utility model, screw thread positioning sleeve is close to center-pole, can carry out detachable replacing, and the advantage of do so has two
Individual benefit；
1., easily manufactured, if being made as monoblock type, interior grooves cannot be processed, and lathe cannot be clamped and washed；
2., use, it is easy to maintenance, if guiding centre bar or screw thread positioning sleeve are damaged, can individually be changed,
Without the need for integral replacing.
Exemplary description is carried out to the utility model above in conjunction with accompanying drawing, it is clear that realization of the present utility model is not received
The restriction of aforesaid way, if the various improvement that method design of the present utility model and technical scheme are carried out are employed, or without
Improve and design of the present utility model and technical scheme are directly applied to into other occasions, in protection domain of the present utility model
It is interior.
