Abstract
The utility model discloses an engine test bench coupling wheel pin disassembly tool. The engine test bench coupling wheel pin disassembly tool is structurally characterized in that the engine test bench coupling wheel pin disassembly tool is a cylinder, the upper end of the cylinder is provided with a hexagon nut, a through groove is formed in the lower end of the cylinder, the groove width of the through groove is larger than the thickness of a coupling wheel pin cap by 1mm, the groove depth of the through groove is larger than the height of the coupling wheel pin cap by 1mm, and the external diameter of the cylinder disassembly tool is less than the inner diameter of a pin through hole in a test bench coupling wheel set by 1mm. When the test bench coupling wheel set is disassembled, the front end of the engine test bench coupling wheel pin disassembly tool is inlaid in the pin through hole of the coupling wheel set, and then a coupling wheel pin is fixed by using a wrench, and finally a nut on a thread segment of the coupling wheel pin is rotated by using another wrench, and meanwhile assembly or disassembly can be facilitated. The engine test bench coupling wheel pin disassembly tool has the advantages of being simple to manufacture, convenient to use, and capable of performing fastening or the disassembly after the engine test bench coupling wheel pin disassembly tool sleeves the head of the coupling wheel pin, solving the problem that the head of the coupling wheel pin is difficult to fix, and effectively improving assembly efficiency of a test bench.
Description
Technical field
The utility model belongs to machine tool, is specifically related to a kind of to the instrument that wheel pin is dismantled in threst stand.
Background technology
At engine, dispatch from the factory in performance test program, must adopt dynamometer machine to detect the power output of engine, now engine will be by being connected with dynamometer machine centering wheels.During connection, must guarantee that the concentricity of engine and two axis of dynamometer machine, in the scope of allowable tolerance, could measure engine property indices objective and accurately.But after having tested, when engine is separated with dynamometer machine, very difficult to wheel pin on wheels of dismounting.This is because be counter sink to the installing hole on wheels, while dismantling wheel pin, is difficult to its head to fix, and causes dismounting inconvenience, length consuming time.
The utility model proposes a kind ofly easily to wheel pin extracting tool, can solve the fixing difficult problem to wheel plunger portion, and using method is simple, can reduce the working time, effectively increases work efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of threst stand to wheel pin extracting tool.
For realizing the method that its object adopts, be: extracting tool is cylinder, cylindrical upper end is hexagonal (hexagon)nut, cylindrical lower end has groove, the groove width of groove is greater than the thickness 1mm to wheel lug cap, the groove depth of groove is greater than the height 1mm to wheel lug cap, and the cylindrical external diameter of extracting tool is less than test-bed to the pin punch inside diameter 1mm in wheels.
The beneficial effect of feature of the present utility model and generation is, wheel pin extracting tool is made simply, very easy to use, be sleeved on and can carry out fastening or dismounting to wheel pin head, solved the fixing difficult problem of wheel pin head, test-bed efficiency of assembling is effectively improved.
Accompanying drawing explanation
Fig. 1 is surface structure sketch of the present utility model.
Fig. 2 is that the utility model is implemented theory structure schematic diagram.
Fig. 3 is that the utility model is implemented illustration.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, structure of the present utility model is further described.
Threst stand is to wheel pin extracting tool, and its structure is: extracting tool 1 is cylinder, and cylindrical upper end is hexagonal (hexagon)nut, and cylindrical lower end has groove.The groove width of groove is greater than the thickness 1mm to wheel lug cap 2; The groove depth of groove is greater than the height 1mm to wheel lug cap; The cylindrical external diameter of extracting tool is less than test-bed to the 4 internal diameter 1mm that bore a hole of the pin in wheels.
When need to be to wheels be docked or being dismantled in threst stand, extracting tool front end is bumped in the pin perforation in wheels, now the groove of extracting tool front end just in time with to wheel lug cap engages, then utilize spanner to fix wheel pin, finally, with the nut of another spanner rotation to wheel pin thread section, now can conveniently assemble or dismantle.
