Abstract
The utility model provides a floating squeeze head which comprises a squeeze head seat fixed on a press; the head of the squeeze head is provided with a chamfer angle; the floating squeeze head further comprises a cavity body axially arranged along the squeeze head seat at the end of the squeeze head seat, which is opposite to the press, and a connecting rod arranged at the head of the squeeze head and inserted into the cavity body; the connecting rod and the cavity body are in clearance fit; and the squeeze head seat and the head of the squeeze head are in movable connection. The floating squeeze head reduces the gap between the two work pieces after press mounting and improves press mounting precision and yield.
Description
Technical field
The utility model relates to a kind of press-loading device, particularly relates to a kind of unsteady pressure head that is used to press-fit workpiece.
Background technology
Press-fiting at present all kinds of pressure heads that use in the process, great majority are fixing pressure head, pressure head comprise be fixed on press seaming chuck seat and with the pressure head head of pressing head seat one, in the process that two workpiece is fitted in together, wherein a workpiece be placed on another workpiece above, to aim between two workpiece, but the pressure head head can only vertical motion, in press-fiting the process of workpiece, be difficult to be placed on above the workpiece card close, two workpiece after that press-fits tend to produce big slit, if but reduce the slit by strengthening press pressure, can cause the workpiece crushing, and in the actual mechanical process, it or not too big that precision improves.Therefore can cause a lot of waste products after the processing, influence production efficiency.Particularly when the workpiece that has chamfering is pressed fit into another part workpiece, even the pressure head head is provided with chamfering, pressure head head and the workpiece that has chamfering are fitted, but after having press-fited, still big slit can be produced between two workpiece, the requirement of work can't be satisfied.
Summary of the invention
The purpose of this utility model is to provide the slit between a kind of two workpiece that make after having press-fited to reduce, and improves the unsteady pressure head that press-fits precision.
A kind of unsteady pressure head of the utility model, comprise and be fixed on press seaming chuck seat and the pressure head head that is connected with pressing head seat, the pressure head head is provided with chamfering, comprise that also described pressing head seat is provided with the connecting portion that is provided with the described axially extending bore of insertion along the through hole and the pressure head head of the axial setting of pressing head seat with respect to an end of press, described connecting portion and axially extending bore are matched in clearance.
The utility model is compared with prior art: because connecting portion and axially extending bore are matched in clearance, in the process that press-fits, guarantee that the pressure head head is having certain amount of exercise in the radial direction, the chamfering energy automatic capturing of pressure head head, can fit with being pressed the chamfering on the workpiece, make by the contact-making surface of the workpiece of pressing workpiece to be mated and fit, gap between two workpiece after press-fiting is reduced, precision reaches the requirement of technology, raising press-fits precision, is provided with spring and bar hole between pressure head head and the pressing head seat simultaneously, makes the pressure of press suitable, can not damage workpiece by pressure, improve the yield rate of product.
Description of drawings
The structural representation of a kind of unsteady pressure head that Fig. 1 provides for the utility model.
The specific embodiment
With embodiment the present invention is described in further detail with reference to the accompanying drawings below:
As shown in Figure 1, a kind of unsteady pressure head that the utility model provides, comprise and be fixed on press seaming chuck seat 1 and the pressure head head 2 that is connected with pressing head seat 1, pressure head head 2 is provided with chamfering 21, comprise that also described pressing head seat 1 is provided with the connecting rod 22 that is provided with the cavity 11 that inserts described pressing head seat 1 along the through hole and the pressure head head 2 of the axial setting of pressing head seat with respect to an end of press, described connecting rod 22 is a matched in clearance with the cavity 11 of pressing head seat 1, described pressing head seat 1 and pressure head head 2 guarantee that for flexibly connecting pressing head seat 1 and pressure head head 2 have certain amount of exercise on radial direction and axial direction.
In the present embodiment, unsteady pressure head also comprises the through hole that radially is provided with along pressing head seat 1 and connecting rod 22, and the radial direction through hole of described pressing head seat 1 and described cavity 11 intersect.Also comprise the connecting portion that is used for fixing pressure head head 2 and pressing head seat 1, described connecting portion passes outer surface, cavity 11 and the described connecting rod 22 of pressing head seat 1 successively, be arranged in the radial direction through hole of pressing head seat 1, connecting portion is a bearing pin 4 under the preferable case, the two ends of bearing pin 4 are provided with back-up ring 3, the through hole of described connecting rod 22 is a bar hole 5, and described bar hole 5 is the axial settings along connecting rod 22.The elastomeric element of pressing head seat 1 in cavity 11 is being set, and under the preferable case, described elastomeric element is a spring 6, described spring 6 is positioned at repeatedly on the bar 22, when unsteady pressure head was in original state, spring did not stress, and bearing pin 4 is arranged in the end of bar hole 5 away from pressure head head 2.When driving pressure head, press presses down, when pressure head head 2 contacts with workpiece, workpiece is to the reaction force of pressure head head 2, pressure head head 2 is moved upward, be arranged in bar hole 5 end near pressure head heads 2 up to bearing pin 4, spring 6 is subjected to the pressure of pressure head head 2 simultaneously, when the pressure balance of the elastic force of spring 6 and pressure head head 2, pressure head head 2 ability press-fit workpiece along with press presses down.Owing to spring 6 is set and bar hole 5 can guarantee that the pressure of press is suitable, the frictional force that only need overcome two workpiece contact-making surface inwalls get final product, thereby assurance can not damaged workpiece by pressure.
In press-fiting the process of workpiece, because described connecting rod 22 is a matched in clearance with the cavity 11 of pressing head seat 1, guarantee that pressure head head 2 is having certain amount of exercise in the radial direction, can be by chamfering 21 centerings, the chamfering 21 of pressure head head is fitted with the chamfering of being pressed workpiece, pressed workpiece and another workpiece alignment, press drives pressure head head 2 and presses down, pressure head head 2 is contacted with pressing workpiece, when the elastic force of spring 6 reaches balance, press drives pressure head head 2 to be continued to press down, and overcomes the frictional force of two workpiece contact-making surface inwalls, and two workpiece are press fit into together.
The specific embodiment of the above is a better embodiment of the present utility model, is not to limit concrete practical range of the present utility model with this, and scope of the present utility model comprises and is not limited to this specific embodiment; The equivalence variation that all shapes according to the utility model, structure are done all comprises in the protection domain of the present utility model.
