Abstract
The utility model relates to a composite positioning and clamping balancing clamp for a clutch pressure plate, and aims to eliminate the influence caused by the unavailability of a dynamic balancing machine for positioning clearance compensation and achieve high balancing repeatability precision of a processed pressure plate. The balancing clamp adopts the specific structure that a clamp body is positioned through a mandrel and then fixed with the balancing machine through screws I; an upper cover is mounted on an elastic expansion ring through screws II; the lower end of a nut in threaded connection with the mandrel is placed in a hollow cavity formed by the elastic expansion ring and the upper cover; thrust ball bearings are mounted on the nut; and the elastic expansion ring enters an expansion surface through a guide surface of the clamp body, and is laterally positioned through round pins. The utility model has the benefits that the balancing clamp eliminates the influence caused by the unavailability of the dynamic balancing machine for positioning clearance compensation, and achieves high balancing repeatability precision of the processed pressure plate; the performance of a clutch assembly is improved; and not only is the labor intensity of employees reduced, but also the work efficiency is improved.
Description
Technical field
The utility model belongs to the auto parts machinery field.
Background technology
Traditional machining frock design, the positioning principle of employing is six point locations, and avoids the location as far as possible.Use the most typical plane and two pits location that has, in order to prevent the location, a register pin is a straight pin in its two pin, and another register pin must adopt the chamfered edge latch structure.Because the influence in the right alignment of register pin, position degree and gap, location, its bearing accuracy can only reach about 0.02～0.05mm.The positioning accuracy request of transient equilibrium frock design and the measure of taking are in the design of clutch cover and plate assembly transient equilibrium frock, if adopt this plane and two pits location, then bearing accuracy can not satisfy technological requirement, even the positioning error of 0.02mm, also can make the amount of unbalance (relevant) about assembly generation 200gmm with the quality of assembly, and the total requirement of product amount of unbalance is also only about 100gmm, in other words, even the product amount of unbalance is 0, because the positioning error of frock also can be substandard product with the specification product erroneous judgement.
Because dynamic balance accuracy technological requirement height, in order to meet the demands, the transient equilibrium lathe has all adopted autocompensation installation to eliminate the right alignment of register pin, the influence of position error, but it can not eliminate the influence in gap, location, also the situation that bearing accuracy does not reach technological requirement will occur in the actual production.
Summary of the invention
The purpose of this invention is to provide in a kind of elimination dynamic balancing machine the location noncompensable influence in gap, make the platen after the processing, the compound location that the balance repeatable accuracy is good clamps clutch pressure plate balance anchor clamps.
The utility model concrete structure is:
A, body are fixed by screw I and equilibrator by back, mandrel location;
B, loam cake are installed on the elastic piston ring by the screw II, and the nut lower end that is connected with mandrel thread places in the cavity of being made up of elastic piston ring and loam cake, and thrust ball bearing is installed;
C, elastic piston ring enter the tensioner face by the guide surface on the body, and by location, straight pin side.
The utility model is equipped with O type circle on elastic piston ring is enclosed within mandrel on the mandrel.
The beneficial effects of the utility model are:
1, adopt compound location to clamp clutch pressure plate balance anchor clamps and eliminated in the dynamic balancing machine the location noncompensable influence in gap,
Platen balance repeatable accuracy after the processing is good.
Because what these anchor clamps adopted is the mode that tensioner is located in piston ring and body guiding earlier again, adopt the straight pin location simultaneously between elastic piston ring and body, make the piston ring radial axis not have relativity shift, thereby can as common piston ring location, not produce locating bias.Solve the transient equilibrium lathe and can not eliminate the influence in gap, location.
2, the clutch assembly performance is improved.
Because the amount of unbalance of platen occupies very big proportion in clutch assembly, so the transient equilibrium accuracy of platen has played conclusive effect to the comfortableness of clutch assembly and car load.
3, alleviated staff labor intensity, increased work efficiency.
Since nut thrust ball bearing all has been installed up and down, make in the nut rotation at work and reduced friction force between loam cake and elastic piston ring, therefore alleviated personnel labor, improved work efficiency.
Description of drawings
Fig. 1 is the utility model structure cut-open view.
Embodiment
The utility model concrete structure is:
A, body 1 are fixed by screw I 3 and equilibrator by back, mandrel 10 location;
B, loam cake 8 are installed on the elastic piston ring 9 by screw II 4, and nut 6 lower ends that are threaded with mandrel 10 place in the cavity of being made up of elastic piston ring 9 and loam cake 8, and thrust ball bearing 7 is installed;
C, elastic piston ring 9 enter tensioner face 12 by the guide surface on the body 1 11, and by location, straight pin 2 sides.
The utility model is equipped with O type circle 5 on elastic piston ring 9 is enclosed within mandrel 10 on the mandrel 10.
Body is fixed with equilibrator by back, mandrel location, and elastic piston ring is connected with loam cake, nut bearing etc. through screw and is one, and elastic piston ring enters the inclined-plane tensioner after the guiding of body guiding, improved bearing accuracy.The rotation nut is equipped with thrust ball bearing and O RunddichtringO up and down, makes and can increase work efficiency in tensioner with when unclamping.Rotate when downward at nut, elastic piston ring is by the effect spreading on body guide surface and inclined-plane, makes clamping work pieces.
At first this body and function screw is linked to each other with equilibrator, and the right alignment that detects the flatness of last working surface of body and spigot surface with dial gauge respectively is in the technological requirement scope.Detect qualified back the balance anchor clamps are done compensation correction.
