The utility model discloses simple structure facilitates the use, has avoided balanced piston to take place the turn-ups of lip's the condition when the assembly, has improved assembly qualification rate and assembly efficiency greatly to manufacturing cost has been reduced.
Description
Technical Field
The utility model relates to a derailleur field especially relates to a buncher's balanced piston assembly direction frock.
Background
When the clutch assembly of the continuously variable transmission is used for press mounting of the balance piston on production line equipment, the lip of the piston is made of rubber ACM materials, so that the hardness is soft, the guide angle of a to-be-mounted fitting piece is not enough to complete the guide, the rubber lip flanging is easily generated in the press mounting process, the yield is low, and the production beat and the cost are influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems in the prior art, the utility model provides a buncher's balanced piston assembly direction frock.
The utility model provides a buncher's balanced piston assembly direction frock, including the direction barrel, the direction barrel includes pre-installation section, changeover portion and adaptation section, the changeover portion is connected the pre-installation section with the adaptation section, pre-installation section internal diameter is greater than adaptation section internal diameter, the changeover portion internal diameter is held to adaptation section by the pre-installation section and is reduced gradually, adaptation section internal diameter is the same with the internal diameter of waiting to install the fitting piece.
As a further improvement, the free end of the adaptive section is provided with a limit part adapted to the edge of the fitting piece to be mounted.
The utility model has the advantages that: when the balance piston is pressed and assembled, the adaptive section of the guide cylinder body is arranged on the fitting piece to be installed, the balance piston is inserted from the preassembly section of the guide cylinder body, the balance piston can be easily installed in the preassembly section due to the fact that the inner diameter of the preassembly section is large, when the balance piston is pressed downwards, the balance piston can pass through the transition section and the adaptive section and finally enters the fitting piece to be installed, the lip mouth of the balance piston gradually shrinks inwards in the installation process, and therefore flanging can be avoided in the pressing process, and the assembly qualification rate is guaranteed.

Detailed Description
As shown in fig. 1 and fig. 2, the utility model discloses a buncher's 5 assembly direction frocks of balanced piston, including direction barrel 1, direction barrel 1 includes pre-installation section 2, changeover portion 3 and adaptation section 4, changeover portion 3 is connected pre-installation section 2 with adaptation section 4, 2 internal diameters of pre-installation section are greater than 4 internal diameters of adaptation section, 3 internal diameters of changeover portion are reduced to 4 ends of adaptation section by 2 ends of pre-installation section gradually, 4 internal diameters of adaptation section are the same with the internal diameter of waiting to install fitting piece 6.
During installation, the end part of the adaptive section 4 of the guide cylinder body 1 is butted with the fitting piece 6 to be installed, then the balance piston 5 is inserted into the preassembly section 2 of the guide cylinder body 1, the preassembly section 2 is large in inner diameter, so the installation is easier, the balance piston 5 is pressed down afterwards, the transition section 3 is used for connecting the preassembly section 2 and the adaptive section 4, the inner diameter of the transition section is gradually reduced, the lip 51 of the balance piston 5 is gradually contracted inwards along with the continuous pressing down of the balance piston 5, and finally the transition section 4 enters the fitting piece 6 to be installed, so the flanging condition of the lip 51 is avoided, the assembly qualification rate is greatly improved, and the assembly efficiency is also improved.
In this technical scheme, 4 free ends in adaptation section are equipped with and treat spacing portion 41 of installation fitting piece 6 edge adaptation, and its edge of treating installation fitting piece 6 all can set up the direction fillet, and 4 tip in adaptation section are equipped with the spacing portion 41 with the adaptation of direction fillet, can be better with treat that installation fitting piece 6 docks, guarantee that the internal diameter is the same.
The utility model discloses simple structure facilitates the use, has avoided balanced piston 5 to take place the turn-ups of lip 51 the condition when the assembly, has improved assembly qualification rate and assembly efficiency greatly to manufacturing cost has been reduced.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
Claims (2)
1. The utility model provides a buncher's balanced piston assembly direction frock which characterized in that: the guide cylinder comprises a guide cylinder body, wherein the guide cylinder body comprises a preassembly section, a transition section and an adaptation section, the transition section is connected with the preassembly section and the adaptation section, the inner diameter of the preassembly section is larger than that of the adaptation section, the inner diameter of the transition section is gradually reduced from the end of the preassembly section to the end of the adaptation section, and the inner diameter of the adaptation section is the same as that of a fitting piece to be installed.
