The removable structure is the cover plate pin hole being arranged on cover plate.
The adjusting rod is the bolt being threadedly connected on cover plate.
Be provided with the cover plate for for the installation of working shaft guiding movement and limit the installation that working shaft circumferentially rotates
Hole.
A kind of technical scheme of test tool of the present invention is：A kind of test tool, including axis are vertically extending
Overcoat and guiding movement be assemblied in working shaft in overcoat, be correspondingly arranged in overcoat and the working shaft circumferential side wall for treating
The shearing perforation that test pin loads, the test tool also include pin shearing test servicing unit, the pin shearing test auxiliary dress
Put including the cover plate vertically extending for the thickness of slab by removable structure and the removable assembly connection of overcoat, set on cover plate
Have for positioning adjustable adjusting rod that block coordinates and upper and lower in the axial direction with working shaft.
The removable structure is the cover plate pin hole being arranged on cover plate, is provided with the upper surface of the overcoat and cover plate
Overcoat pin hole corresponding to pin hole, the cover plate are fixed on by the tight fit of pin and cover plate pin hole and overcoat pin hole
Put outside.
The adjusting rod is the bolt being threadedly connected on cover plate.
Be provided with the cover plate for for the installation of working shaft guiding movement and limit the installation that working shaft circumferentially rotates
Hole.
Beneficial effects of the present invention are：One kind pin shearing test servicing unit, including the lid with the removable assembly connection of overcoat
Plate, upper and lower adjustable adjusting rod for positioning block cooperation in the axial direction with working shaft is provided with cover plate, this is auxiliary
Help device to be connected by removable structure with overcoat, may apply on the pin shear test frock of different size, pass through adjusting rod
Regulation on the working shaft progress axial direction of different pin shear test frocks is positioned, in order to overcoat shearing perforation and work
The alignment of axle shearing perforation in the vertical direction, and the versatility of the servicing unit is realized, save cost.
Further, it is provided on the cover board that working shaft guiding movement is installed and limits what working shaft circumferentially rotated
Mounting hole, with reference to the adjusting rod positioning to working shaft in the axial direction, it is ensured that overcoat shearing perforation is with working shaft shearing perforation upper
It is aligned while on lower direction and circumference, so as to the loading of pin to be detected.

Embodiment
A kind of structural representation of test tool as shown in Figure 3-4, including the vertically extending overcoat 5 of axis and is led
It is correspondingly arranged in the circumferential side wall of the working shaft 6 being assemblied in movement in overcoat, overcoat 5 and working shaft 6 and is filled for pin to be detected
The overcoat shearing perforation 7 and working shaft shearing perforation 8 entered, overcoat shearing perforation 7 and working shaft shearing perforation 8 are formed when being aligned to be sheared for pin
The test hole of experiment, dismountable pin shearing test auxiliary mould is provided with overcoat 5, and pin shearing test auxiliary mould includes position
The cover plate 9 with 5 removable assembly connection of overcoat in the upper end of overcoat 5, have on cover plate 9 and positioned in the axial direction with working shaft 6
Block coordinates the adjusting rod being aligned in the vertical direction in order to working shaft shearing perforation 8 and overcoat shearing perforation 7, is adjusted in the present embodiment
Pole be threadedly connected to it is on cover plate 9 and extend into the inner chamber of overcoat 5 be used for working shaft 6 axially position block coordinate
Bolt 10, the bolt penetration hole 13 installed for bolt 10, cover plate pin hole 14 are provided with cover plate 9 and is oriented to for working shaft upper end
Mounting hole 15 that is installing and limiting the flat that working shaft 6 rotates in circumferential direction, on the upper surface of overcoat 5 with cover plate pin hole
14 are correspondingly arranged on overcoat pin hole, and cover plate 9 is removable by the tight fit of pin 12 and cover plate pin hole 14 and overcoat pin hole
Assembly connection is on overcoat 5.The upper end of working shaft 6 have be adapted with the geomery of mounting hole 15 can guiding movement flat post
The installation bar portion 6-1 of shape, lower end are the cut part 6-2 being adapted with the inner chamber of overcoat 5, and cut part 6-2 upper surface is formed and spiral shell
The stopping surface 11 that the positioning block of bolt 10 in the axial direction coordinates, the mounting hole 15 of flat and the installation bar portion 6-1 of flat column
To coordinating to carry out positioning block in circumferential direction to working shaft 6, it is ensured that the shearing perforation 8 of overcoat shearing perforation 7 and working shaft is upper
