The sliding block 4 of cooperation, the fixed block 7 and the clamp system for being used to fix bump leveller 11 on the sliding block 4 are arranged on, and set
It is used for the spacing adjusting mechanism of spacing regulation between the fixed block 7 and the sliding block 4；
The spacing adjusting mechanism include be arranged on the fixed block 7 the first fixing hole 15, be arranged on the sliding block 4
The second fixing hole 12 that is upper and matching with first fixing hole 15, is fixed through first fixing hole 15 and described second
Hole 12 and for the adjusting rod 2 of adjusting slider 4 and the spacing of fixed block 7.
The clamp system includes being arranged on the first fore-set 6 on the fixed block 7, and be arranged on the sliding block 4 and
The second fore-set 5 for clamping the bump leveller 11 is engaged with first fore-set 6；And first fore-set 6 and second pushes up
The mirror image each other of post 5.
The sliding equipment includes two parallel grooves 14 being arranged on the base body 1, and it is parallel described to be arranged on two
Gate pedestal 9 in chute 14, and the both ends of the gate pedestal 9 insert in the chute 14 and with the shape of the chute 14
Shape mutually agrees with, and the sliding block 4 is set on the gate pedestal 9.
First fixing hole 15 is through hole, and second fixing hole 12 is screwed hole, and the adjusting rod 2 is bolt.
The front end of first fore-set 6 sets the fixed column 13 being engaged with the bump leveller 11, the fixed column 13 and institute
The internal diameter gap for stating the inner ring 113 of bump leveller 11 coordinates, and the diameter of first fore-set 6 is more than the inner ring of the bump leveller 11
113 internal diameter.
The both sides of described one end of bump leveller 11 set mounting ear 111, and hole 112 is threaded on the mounting ear 111, described
Vibrating sensor is connected by screw with the mounting ear 111.
The fixed block 7 and the sliding block 4 are the platy structure that side is in isosceles trapezoid.
The bolt used in the present embodiment works as the first fixing hole and uses screwed hole for the threaded rod that one end is turret head
When, the hand of spiral in the second fixing hole is opposite to that, and then realizes that sliding block leans on to fixed block when ensuring to rotate in one direction
Closely, sliding block away from fixed block, and then realizes the compression and removal to bump leveller during reverse rotation；The chute used in the embodiment
For rectangle chute, while lubricating oil or graphite linings can be coated wherein in order to ensure the effect of slip, reduce the frictional force of slip,

The second fixing hole is designed as through hole in the embodiment, i.e. the unthreaded hole being commonly called as, and set in sliding block outer wall correspondence position
Existing nut is put, is welded thereon, while in order to reduce the difficulty of processing, the aperture of the second fixing hole of setting is greater than
The aperture of first fixing hole so that the welding of nut has larger tolerance；And the base body used is somebody's turn to do for rectangular parallelepiped structure
Structure is beneficial to set the component such as fixed block and chute on base body, and in order to keep the stationarity of base body, in base
Corner below body sets support block, avoids base body from directly being contacted with test desktop and causes jiggly phenomenon；Support
The friction shim set below block, can increase the steadiness of base body, and avoid support block from being contacted firmly with desktop, cause to draw
Trace damages.
Application method of the present utility model：Passing through swivel bolt so that sliding block is translated by gate pedestal on chute, from
And the distance between two fore-sets is adjusted, the inner ring of one end of bump leveller is inserted in the fixed column of fore-set front end, then rotates spiral shell
Bolt so that sliding block moves to the direction of fixed block so that another fixed column inserts the other end of bump leveller, passes through two fore-sets
Bump leveller is fixed, is then arranged on vibrating sensor on the mounting ear of bump leveller, can be to test bump leveller.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement
The scope of protection of the utility model is also should be regarded as with retouching.
