Abstract
The utility model discloses an adaptive connection device for a hollow axle and an ultrasonic flaw-detecting machine. The device comprises a probe arrangement cylinder, a front connecting disk, clamping jaws and a rocker arm assembly, wherein the probe arrangement cylinder is connected with the front connecting disk; three groups of clamping jaws are arranged on the front connecting disk; the rocker arm assembly is in threaded connection with the probe arrangement cylinder. The matched connection of a hollow vehicle axle and an adapter is realized. The device has a simple and practical structure.
Description
Technical field
The utility model relates to a kind of coupling arrangement, particularly a kind of for the adaptive coupling arrangement of tubular shaft ultrasonic flaw-detecting machine, is to guarantee that ultrasonic probe enters in tubular shaft smoothly, guarantees the correct position key component of flaw detection smoothly of probe.
Background technology
At present, the hole-bored axle from end to end that the tubular shaft internal diameter that we visit is 30～80mm, every walking 30000～400000km need to make regular check on.Because the axletree of existing operation is different from traditional axletree, it is hole-bored axle from end to end.When portable tubular shaft ultrasonic test equipment is detected a flaw, the inner hole surface that flaw detection surface of contact is hole-bored axle from end to end, and because the car model of current domestic operation is various, and hollow axle end installation accessories complexity, situation is different, so, need to design supporting adapter, complete flaw detection operation according to the different inner diameters of hole-bored axle from end to end and axle head state.And then being connected of vehicle hole-bored axle from end to end and adapter also just needs special coupling arrangement.
Summary of the invention
For achieving the above object, realize being connected of vehicle hole-bored axle from end to end and adapter, it is a kind of for the adaptive coupling arrangement of tubular shaft ultrasonic flaw-detecting machine that the utility model provides, comprise feeler lever placing tube, anterior terminal pad, claw and rocker arm assembly, feeler lever placing tube is connected with anterior terminal pad, three groups of claws are set on anterior terminal pad, and described rocker arm assembly is threaded with feeler lever placing tube.
Further, rocker arm assembly comprises handle and travelling nut, and described handle is arranged on the front end of travelling nut to drive travelling nut to rotate.
Further, claw comprises that fore paw end part, pawl arm divide and rear solid end end part, and the pawl arm of described claw divides by rotating shaft and is arranged on anterior terminal pad.
Further, travelling nut is provided with annular groove, and the rear solid end end part of claw is arranged in the annular groove on travelling nut; In the rear solid end end part of claw, bearing is installed.
By technique scheme, the utility model is a kind of realizes being connected of vehicle hole-bored axle from end to end and adapter for the adaptive coupling arrangement of tubular shaft ultrasonic flaw-detecting machine, simple and practical.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation for the adaptive coupling arrangement of tubular shaft ultrasonic flaw-detecting machine of the utility model;
Fig. 2 is a kind of structural representation being connected with adapter for the adaptive coupling arrangement of tubular shaft ultrasonic flaw-detecting machine of the utility model;
Embodiment
One is as shown in Figure 1-2 for the adaptive coupling arrangement of tubular shaft ultrasonic flaw-detecting machine, comprise feeler lever placing tube 1, anterior terminal pad 2, claw 3 and rocker arm assembly 4, feeler lever placing tube 1 is connected with anterior terminal pad 2, three groups of claws 3 are set on anterior terminal pad 2, and described rocker arm assembly 4 is threaded with feeler lever placing tube 1.Rocker arm assembly 4 comprises handle 5 and travelling nut 6, and described handle 5 is arranged on the front end of travelling nut 6 to drive travelling nut 6 to rotate.Claw 3 comprises that fore paw end part, pawl arm divide and rear solid end end part, and the pawl arm of described claw (3) divides by rotating shaft and is arranged on anterior terminal pad 2.Travelling nut 6 is provided with annular groove, and the rear solid end end part of claw 3 is arranged in the annular groove on travelling nut 6.In the rear solid end end part of claw 3, bearing 7 is installed.
The now adaptive coupling arrangement of the ultrasonic flaw-detecting machine of design, is to guarantee that ultrasonic probe enters in tubular shaft smoothly, guarantees the correct position key component of flaw detection smoothly of probe.
The function of adaptive coupling arrangement is in the time of flaw detection, by manually probe placement cylinder 1 being directed to tubular shaft adapter 8 end face of flange place coarse alignments, then rotating hand 5 travels forward travelling nut 6 to drive three rocking arm automated movements, aligning clamping, and provide certain clamping force, complete defectoscope, adapter 8 and hollow shaft alignement and link together, for ultrasonic feeler lever provides flaw detection passage the enclosed environment relative with.
Concrete operations are as follows:
A operating personnel only need rotate 45 degree to clockwise direction by handgrip 5, actual namely motionless by being fixed on interior silk braid in feeler lever placing tube 1, rotate travelling nut 6 ﹙ to timing direction and make silk braid move horizontally backward 2 millimeters apart from female ﹚ 45 degree of shape spiral shell can to complete clamping object.
B is when silk braid moves, and the handtailor bearing being arranged on rocker arm assembly 4 moves in the female ﹚ ring groove of shape spiral shell at travelling nut 6 ﹙ simultaneously, thereby and three rocking arms of promotion move realization clamping inwards.
The anterior terminal pad 2 of C is designed with adapter 8 flange localization parts and forms a hook-shaped, when operation, defectoscope is tangled adapter 8 flanges with structure herewith, has realized concentric locating simultaneously, and then turning handle is realized and being clamped.
The foregoing is only better enforcement one example of the present utility model, be not limited to the utility model, all any modifications of making, be equal to replacement and improvement etc., within being all contained in protection domain of the present utility model within the utility model spirit and principle.
