Abstract
A constant velocity universal joint cover seat binding-off device is composed of a clamping seat part and a clamp part, wherein, the clamping seat part comprises a base and a sleeve ring fixed on the external edge of the base. The clamp part comprises a conical pressure head, a large positioning sleeve and a pressure bar both connected inside the inner chamber of the conical pressure head. A ring groove is preset between the base of the clamping seat part and the sleeve ring. The inside of the ring groove is axially provided with extruding blocks at intervals. A sliding fit is provided between the large positioning sleeve of the clamp part and the pressure bar. The pressure bar located above a lower positioning sleeve is fixedly provided with a small positioning sleeve. A spring is equipped between the large positioning sleeve and the small positioning sleeve. Compared with the prior art, the cover seat is ensured not to suffer deformation resulted from hard pressure due to the facts that the extruding blocks distributed along the periphery of the clamping seat part cooperate with the conical pressure head of the upper clamp part and the cover seat is cooperating with the large positioning sleeve, the spring, the small positioning sleeve and the pressure bar. Furthermore, accurate assembly positioning and stroke control can be realized by adjusting the inner conical face depth of the conical pressure head and the pressure stroke of the spring. The assembly quality and the work efficiency of products are significantly improved.
Description
Technical field:
The utility model belongs to CV joint for car assembly equipment field, is specifically related to a kind of constant velocity cardan joint cover seat closing device.
Background technology:
Be furnished with bolt when VL type constant velocity cardan joint uses, the cover seat adopts interference fit.At present the closing device that uses is by deck with fix two parts and forms, wherein the deck part by base, be fixed on the lasso on the outer platform edge of base, fix part by the awl pressure head and be connected big positioning sleeve, the depression bar of boring the pressure head inner chamber.The jackscrew extruding that it closes up and adopts the base top periphery promotes the cover seat with fixing big positioning sleeve partly then and docks the realization closing in workpiece cover mouth.Because the extruding force at each position was unbalanced during jackscrew was adjusted, and fixes part and lack corresponding stroke and cooperate, cause closing in quality and closing in efficient low, influence the use service life of product.
The utility model content:
The purpose of this utility model is exactly the problem that existing closing device occurs in the constant velocity cardan joint assembling process, and the constant velocity cardan joint cover seat closing device of a kind of accurate positioning, highly effective is provided.
Its technical scheme is: be made up of deck and fixing two parts, wherein deck partly comprises base, is fixed on the base lasso on platform edge outward, big positioning sleeve, depression bar that the holding division branch comprises the awl pressure head and is connected awl pressure head inner chamber, it is characterized in that: between the base of deck part and lasso, be preset with cannelure, crushing block is installed in the cannelure vertically at interval; The big positioning sleeve and the depression bar that fix part are slidingly matched, and are fixed with little positioning sleeve on the depression bar above the following positioning sleeve, are provided with spring between the big or small positioning sleeve.
Described crushing block is the overall structure of default 3-20 the axial notch in top.Described crushing block is 3～20 combining structures that briquetting is spaced apart, and each crushing block is connected on the lasso by bolt and extension spring.
The utility model compared with prior art, deck has partly increased along the crushing block of circumferential distribution and has cooperated with the holding division reference cone pressure head on top, realized the balanced contraction of workpiece cover mouth periphery, cover seat and being used of positioning sleeve, spring, little positioning sleeve and depression bar greatly simultaneously, guaranteed that cover seat can not be subjected to rigid pressure and is out of shape, in addition by adjusting the awl pressure head inner conical surface degree of depth and spring pressure stroke, can realize the accurate location and the Stroke Control of assembling, improve the assembly quality of product greatly, reduce labour intensity, operate simple and effective more.
Description of drawings:
Fig. 1 is a kind of structural representation of duty of exemplary embodiments.
The specific embodiment:
In conjunction with Fig. 1, constant velocity cardan joint cover seat closing device is made up of two parts, workbench 11, base 1, lasso 2, extension spring suspension ring 3, extension spring 4, briquetting 5 are formed the deck parts, and big positioning sleeve 7, compression spring 8, little positioning sleeve 9, awl pressure head 6, depression bar 14 compositions fix part.Base 1 is fixed on the workbench 11, base 1 is a step broadening formation cylindrical tube shape, lasso 2 is installed on base 1 outside boss, and it is fastening with screw, lasso 2 tops are fixed with extension spring suspension ring 3, briquetting 5 is contained in the groove between base 1 and the lasso 2, is connected to lasso 2 secure fit by extension spring 4.The top of the step of falling trumpet type awl pressure head 6 is connected with hydraulic press pressure head 10, awl pressure head 6 inner chamber compression column with fixed 14, and little positioning sleeve 9 is fixed on depression bar 14 tops, by spring 8 and bottom nut big positioning sleeve 7 is limited in the depression bar 14 bottom effective travels downwards.
The course of work is, cover seat 13 is enclosed within on the lower port of big positioning sleeve, constant velocity cardan joint (workpiece) 12 is put into the deck part, hydraulic press pressure head 10 is descending, awl pressure head 6 is descending with hydraulic press pressure head 10, and descending process medi-spring 8 is compressed, and workpiece is produced pressure, make that workpiece and base 1 are sturdy, it is crooked to prevent that it from producing under the effect of external force.The conical surface of final awl pressure head 6 contacts with briquetting 5 (being cut into 12 lobes by integral body) and forces it to shrink to the center, the local generation of cover seat plastic deformation under the effect of briquetting 5, large end face up to awl pressure head 6 contacts with the end face of lasso 2, and awl pressure head 6 can't continue descending again, and closing in work is finished.Hydraulic press pressure head 10 is up, and briquetting 5 resets under the pulling of extension spring 4, takes out workpiece.
