Description
Technical field
The utility model relates to cross axle processing, particularly a kind of clamping device for processing cross axle.
Background technology
Cross axle is the parts realizing varied angle power transmission, and for needing the position changing transmission axis direction, it is " joint " parts of the universal driving device of automobile driving system, and cross axle is one of cross shaft rigid universal joint key component.When vehicle travels, the direction of transmitting due to moment of torsion is consistent, and the Impact direction of cross axle is also consistent, in the course of time, causes the uneven wear of trunnion journal, and As time goes on, the stressed one side of cross axle just can be worn and torn increasing, grooving, to such an extent as to looseness is made sound.
The lubricating grease of cross axle can note the needle bearing of trunnion journal from lubricating cup, play bearing lubrication effect, reduce the friction of bearing, but the oil circuit of existing cross axle lubricating cup is straight, cause cross axle easily to produce centrifugal force when high-speed motion, to such an extent as to inject lubricating grease in lubricating cup because of high temperature dilution and can be got rid of.And be at present all first to get on the bus out positioning spigot at lathe to the processing of cross shaft hole, on milling machine, then process two ends and the centering of cross axle, and then process on lathe, manufacturing procedure is many, long processing time, and efficiency is low.In addition owing to not using special frock clamp at present, make the workpiece spindle hole site precision that processes low.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides the clamping device for processing cross axle that a kind of structure is simple, easy to operate and cross axle steadiness is good.
The purpose of this utility model is achieved through the following technical solutions: a kind of clamping device for processing cross axle, it comprises upper shell and lower house, hollow-core construction is in the middle part of described upper shell and lower house, and all arcuate socket is offered on four sidewalls of upper shell and lower house, multiple connecting portion is provided with on described upper shell lower end outside wall and on the lateral wall of lower house upper end, connecting portion offers the through hole that connecting bolt passes, upper shell and lower house link together by described connecting bolt, a projection is provided with in the middle part of described lower house, projection offers the groove of a placement cross axle, described upper shell is provided with multiple screwed hole, the housing screw compressing cross axle is installed in described screwed hole.
Arcuate socket on described upper shell is semi-circular hole, and the arcuate socket on lower house is semi-circular hole, and after described upper shell and lower house are connected, two semi-circular hole form a circular port.
Described screwed hole is four, and four screwed holes are evenly distributed on circumferentially same.
Described groove matches with the lower limb of the center axis body of cross axle.
The utility model has the following advantages: clamping device of the present utility model, be provided with upper shell, lower house, lower house is provided with the groove placing cross axle, upper shell is provided with the housing screw compressing cross axle, thus cross axle can not be moved in process, make it have good steadiness, thus ensure that the machining accuracy of cross axle; And the structure of whole device is simple, it is very convenient to operate.

Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Fig. 1 ~ Fig. 3, a kind of clamping device for processing cross axle, it comprises upper shell 1 and lower house 2, hollow-core construction is in the middle part of described upper shell 1 and lower house 2, and arcuate socket 3 is all offered on four sidewalls of upper shell 1 and lower house 2, multiple connecting portion 4 is provided with on described upper shell 1 lower end outside wall and on the lateral wall of lower house 2 upper end, connecting portion 4 offers the through hole that connecting bolt 5 passes, upper shell 1 and lower house 2 link together by described connecting bolt 5, a projection 6 is provided with in the middle part of described lower house 2, the groove 9 of a placement cross axle 7 is offered on protruding 6, described upper shell 1 is provided with multiple screwed hole, the housing screw 8 compressing cross axle 7 is installed in described screwed hole.
In the present embodiment, arcuate socket 3 on described upper shell 1 is semi-circular hole, arcuate socket 3 on lower house 2 is semi-circular hole, after described upper shell 1 and lower house 2 are connected, two semi-circular hole form a circular port, the diameter of circular port is greater than the diameter of the connecting axle of cross axle, is adding man-hour, and the connecting axle of cross axle is through circular port.
In the present embodiment, described screwed hole is four, and four screwed holes are evenly distributed on circumferentially same, are screwed by housing screw 8, and the center axis body of cross axle compresses by four housing screws 8, makes it rotate, moves, thus ensure that machining accuracy.
In the present embodiment, described groove 9 matches with the lower limb of the center axis body of cross axle 7, during use, only need be placed in groove 9 by the center axis body of cross axle 7, then close upper shell 1, and by connecting bolt 5 by upper shell and lower house locking, and then lock housing screw 8, like this, just further add the firm fixed of cross axle 7, ensure that machining accuracy.
The course of work of the present utility model is as follows: be placed in groove 9 by the center axis body of cross axle 7, then close upper shell 1, and by connecting bolt 5, upper shell 1 and lower house 2 are locked, and then lock housing screw 8, cross axle 7 compresses by housing screw 8, it is made to move, and then this clamping device is arranged on lathe, and then lathe completes the processing of two ends connecting axle corresponding to cross axle and centre bore, and then by this clamping device 90-degree rotation, complete the processing of cross axle other two ends connecting axle and centre bore, because cross axle cannot move relative to clamping device, thus the precision of the centre bore making cross axle get on lathe is high, thus ensure that the machining accuracy of cross axle.
