It is accurate and reliable, it is substantially and does percussion by personnel are practical and complete quality verification, many parameters are all not fixed, theoretically strike
When hitting speed increases by 1 times, energy increases by 4 times, so, consistency during in order to ensure to examine every time, it is necessary to correct selected impact
When speed.
Therefore it is badly in need of a kind of test equipment of a set of durable test device as hammer tap test, is surveyed with complete realize
Examination requirement, while improve efficiency and accuracy.
Invention content
The purpose of the present invention is exactly the above problem in order to solve the prior art, provides a kind of hammer and taps fatigue test
Machine ensures that test parameter meets the requirements and controllably, makes the reliability height of test result, repdocutbility high.
In order to achieve the above object, the technical solution that the present invention takes is as follows：
A kind of hammer taps fatigue tester, including cross connecting rod, accumulation of energy connecting rod, compressed spring, bearing spider, rotation horse
Reach, rotate cam, bearing support adjustment mechanism and rack, the cross connecting rod tail portion is abutting stem, one end of abutting stem with
Accumulation of energy connecting rod is hinged, and the protruding portion of the other end and rotation cam connects, and is fixed in rack in the middle part of cross connecting rod and freely turns
It is dynamic；The accumulation of energy connecting rod other end is fixed on bearing spider, and compressed spring is fixed on accumulation of energy connecting rod, when accumulation of energy connecting rod to
Compressed spring is compressed by thrust when moving afterwards；The rotation cam and the rotation axis connection of rotation motor；The branch
It holds branch seat adjusting mechanism with bearing spider to be connected, control taps speed；Bearing spider, rotation motor and bearing support adjustment mechanism
It is both secured in rack.
Further, the cross connecting rod uses telescopic clamping pattern, can test different length, the hammer of weight strikes
Hit test.
Further, the hammer taps fatigue tester and further includes speed sensor, with bearing support adjustment mechanism
Connection.Speed sensor measures the actual speed tapped, adjusts bearing support adjustment mechanism to change the initial of compressed spring
Decrement controls the speed of percussion with this.Further, the speed sensor is sensed using contactless high speed optoelectronic
Device.
Beneficial effects of the present invention：
This set durable test device of hammer percussion fatigue tester provided by the invention, completely realizes test request,
Efficiency and accuracy are improved simultaneously, is embodied in the following aspects：
1st, hammer percussion speed is adjustable, utilizes eccentric wheel mechanical structure and accurate compressed spring energy storage, transient burst of energy
It is converted into hammer and taps kinetic energy, reach test requirements document velocity interval.
2nd, speed is tapped, passes through contactless high speed optoelectronic sensor speed sensor, finding speed.
3rd, frequency is tapped, using the rotating speed of accurate Frequency Converter Control motor, realizes that hammer taps the variation of frequency.
4th, the diversity of sample using telescopic clamping pattern, can test different length, the hammer of weight is tapped and surveyed
Examination.
5th, autostop reaches and is damaged in setting number or hammer test process, photoelectric sensor and electrometer can be used
Number device, ensures autostop.
Hammer provided by the invention taps fatigue tester and brings far-reaching influence to the product laboratory of quality authentication
Power and economic benefit.

Specific embodiment
As shown in Figure 1, hammer provided by the invention, which taps fatigue tester, includes cross connecting rod 1, accumulation of energy connecting rod 2, compression
Spring 3, bearing spider 4, rotation motor 5, rotation cam 6, bearing support adjustment mechanism 7, speed sensor 8 and rack, institute
1 tail portion of cross connecting rod stated is abutting stem 101, and one end of abutting stem 101 and accumulation of energy connecting rod 2 are hinged, the other end and rotation cam 6
Protruding portion connect, the middle part of cross connecting rod 1, which is fixed in rack, to be freely rotated；2 other end of accumulation of energy connecting rod is fixed
In on bearing spider 4, compressed spring 3 is fixed on accumulation of energy connecting rod 2, and compressed spring 3 is pushed away when accumulation of energy connecting rod 2 moves backward
Power and compress；The rotation axis connection of the rotation cam 6 and rotation motor 5；The bearing support adjustment mechanism 7 and bearing
Bearing 4 is connected with speed sensor 8, and control taps speed；Bearing spider 4, rotation motor 5,7 and of bearing support adjustment mechanism
Speed sensor 8 is both secured in rack.
Further, the cross connecting rod uses telescopic clamping pattern, can test different length, the hammer of weight strikes
Hit test.
Speed sensor 8 is connect with bearing support adjustment mechanism 7 and bearing spider 4, measures the actual speed of percussion, is adjusted
Bearing support adjustment mechanism 7 is saved to change the initial compression amount of compressed spring 3, the speed of percussion is controlled with this.Further, institute
The speed sensor stated uses contactless high speed optoelectronic sensor.
It is as follows that hammer provided by the invention taps fatigue tester operation principle：
The hammer that need to be tested is mounted on to the head of cross connecting rod 1；
Rotation cam 6 drives rotation by rotation motor 5, and the protrusion of rotation cam 6 is 601 and the abutting stem of cross connecting rod
101 end thereof contacts so as to which cross connecting rod 1 be driven to rise, make the abutting stem 101 of cross connecting rod that accumulation of energy connecting rod 2 be pushed to move backward,
So as to which compressed spring 3 be made to be compressed by thrust, the energy savings of 5 rotation forces cross connecting rod 1 of motor are got up；
It is disengaged when rotation motor 5 is rotated further up to rotating cam 6 and the abutting stem 101 of cross connecting rod, and cross at this time
The other end of the abutting stem 101 of connecting rod can forward be pushed together by compressed spring 3 of the accumulation of energy connecting rod 2 Jing Guo accumulation of energy, cause cross
Connecting rod 1 moves downward, and reaches the action of hammer percussion；The adjustment of rotational speed by adjusting control rotation motor 5 of the testing machine is surveyed
The percussion frequency of examination, therefore the FREQUENCY CONTROL of the percussion of the equipment is convenient, stablizes；
It taps speed and changes the big of its energy storage by adjusting the decrement of the change compressed spring 3 of bearing support adjustment mechanism 7
Small to be controlled, the speed control method of the equipment simply easily adjusts.
