Description
Technical Field
The utility model relates to a field of spanner instrument fatigue test, concretely relates to ratchet spanner turns to life-span fatigue test machine.
Background
The ratchet wrench is a manual screw tightening and loosening tool, a steering button is usually arranged on various ratchet wrenches, and the ratchet wrench can rotate in one direction through the steering button. The steering button is easy to damage and cannot be used due to malfunction because of small volume, complex structure, adoption of powder metallurgy or zinc alloy die casting and the like. Therefore, it is necessary to develop a fatigue testing device for a steering button, which can replace human hands to test the service life of the steering button after repeated rotation and reversing, and is convenient for enterprises to improve the product.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a ratchet spanner and turn to fatigue test machine in life-span, have inspection convenient and fast, greatly alleviate test intensity of labour and improve the characteristics of inspection efficiency.
The purpose of the utility model is accomplished through following technical scheme: the fatigue testing machine for the steering life of the ratchet wrench mainly comprises a testing platform, wherein a fixing support is arranged on the left side of the testing platform, the ratchet wrench is fixed on the fixing support through a clamp, an air cylinder is arranged on the right side of the testing platform, the left end of a deflector rod is connected with a steering button on the ratchet wrench, the deflector rod is fixed on the fixing support through a deflector rod steering pin, the right end of the deflector rod is fixedly connected with the air cylinder, and the deflector rod rotates up and down under the driving of the air cylinder so as to drive the steering button to rotate left; an induction type counter is arranged right above the air cylinder and used for recording the rotation times of the deflector rod.
Furthermore, the steering button is provided with a small hole, and a steering poking pin is inserted into the small hole and is used for fixedly connecting the poking rod with the steering button.
The utility model has the advantages that:
1. manual tests are replaced, so that the labor intensity and the inspection efficiency of the tests are greatly reduced;
2. according to the detection data and the damage condition, the product structure design is improved in a targeted manner;
3. the defects in the assembly link are found in advance, and the field improvement is carried out in time;
4. the powder metallurgy or zinc alloy die casting of each batch can be subjected to fatigue test firstly during incoming material inspection, and is put into use after being verified to be qualified, so that the loss caused by batch recall due to serious poor quality is effectively avoided.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals: the device comprises a test platform 1, a clamp 2, a ratchet wrench 3, a steering poking pin 4, a poking rod steering pin 5, a poking rod 6, an air cylinder 7, an induction type counter 8, a fixed support 9 and a steering button 10.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawings, the fatigue testing machine for the steering life of the ratchet wrench mainly comprises a testing platform 1, wherein a fixing support 9 is arranged on the left side of the testing platform 1, the ratchet wrench 3 is fixed on the fixing support 9 through a clamp 2, an air cylinder 7 is arranged on the right side of the testing platform 1, the left end of a shifting rod 6 is connected with a steering button 10 on the ratchet wrench 3, the shifting rod 6 is fixed on the fixing support 9 through a shifting rod steering pin 5, the right end of the shifting rod 6 is fixedly connected with the air cylinder 7, and the shifting rod 6 rotates up and down under the driving of the air cylinder 7 so as to drive the steering button 10; an induction type counter 8 is arranged right above the air cylinder 7 and used for recording the rotation times of the deflector rod 6 (the induction type counter 8 counts once when the deflector rod 6 ascends or descends, and thus the steering times of the steering button 10 are recorded); the steering button 10 is provided with a small hole (the diameter of the small hole is matched with that of the steering poking pin 4), and the steering poking pin 4 is inserted into the small hole and is used for fixedly connecting the poking rod 6 with the steering button 10.
Preferably, the front end and the rear end of the ratchet wrench 3 are fixed on the fixing bracket 9 through the clamps 2.
The utility model discloses a working process: before the test is started, a small hole is drilled in a steering button of the ratchet wrench, the diameter of the small hole is matched with that of a steering poking pin, the front end and the rear end of the ratchet wrench are fixed on a fixed support through clamps, the steering poking pin is inserted into the small hole, the steering button is fixedly connected with a poking rod, the air cylinder is started, the poking rod rotates up and down under the driving of the air cylinder to drive the steering button to rotate in a left-right reversing mode simultaneously, the action of rotating the steering button left and right when a hand uses the ratchet wrench is simulated, an induction type counter counts once when the poking rod ascends or descends, the steering times of the steering button are equivalently obtained, and the fatigue life of the steering button is tested.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
