to achieve these goals, the utility model adopts following technical scheme: a kind of racket anti-torsional strength testing machine, comprise frame and the control panel that is arranged on described frame, the left support bar, the right support bar, the disk arm of force, locating device, the racket handle fixture handles, the racket clamping fixture, pointer, the racket gripper cylinder, Left Angle rule and right corner degree rule, described locating device is fixed on described frame, the described disk arm of force is fixed on described locating device, the described disk arm of force also is connected with racket handle fixture handles and pointer, described left support bar and described right support bar all are arranged at the below of described pointer, and Left Angle rule and right corner degree rule are pointed to respectively in the two ends, left and right of described pointer, described left support bar and described right support bar are connected with respectively left cylinder and right cylinder, described racket gripper cylinder is arranged at above described racket clamping fixture.
As a kind of improvement of the utility model racket anti-torsional strength testing machine, be provided with test/return button, release/clamping button, left and right cylinder switch bar and power switch button on described control panel.
As a kind of improvement of the utility model racket anti-torsional strength testing machine, it is inner that described left cylinder and described right cylinder all are arranged at described frame.
As a kind of improvement of the utility model racket anti-torsional strength testing machine, described locating device comprises base and backstay, and the right and left of described base is respectively arranged with aperture.
As a kind of improvement of the utility model racket anti-torsional strength testing machine, be provided with aperture on described left cylinder and described right cylinder.
With respect to prior art, the utility model adopts the disk arm of force, and because disk rotates howsoever, the arm of force is all the same, can not change because of angle, thereby improve the precision of test; And the utility model can reverse on both sides, thereby avoid only single anti-torsional strength on one side of surveying, can not reflect reliably the problem of the anti-torsional strength of whole racket, and can make design or make the racket person and can effectively grasp the quality of its racket and divide equally intensity.In addition, the utility model can apply fixing torsion on racket handle, and the deformation intensity in the time of therefore can being used for the test racket and being subject to reversing judges the anti-torsional strength of racket whereby.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model and beneficial effect thereof are further described, but embodiment of the present utility model is not limited to this.
as shown in Figure 1, a kind of racket anti-torsional strength testing machine that the utility model provides, comprise frame 1 and the control panel 2 that is arranged on frame 1, left support bar 3, right support bar 4, the disk arm of force 5, locating device 6, racket handle fixture handles 7, racket clamping fixture 8, pointer 9, racket gripper cylinder 10, Left Angle rule 11 and right corner degree rule 12, locating device 6 is fixed on frame 1, the disk arm of force 5 is fixed on locating device 6, the disk arm of force 5 also is connected with racket handle fixture handles 7 and pointer 9, left support bar 3 and right support bar 4 all are arranged at the below of pointer 9, and Left Angle rule 11 and right corner degree rule 12 are pointed to respectively in the two ends, left and right of pointer 9, left support bar 3 and right support bar 4 are connected with respectively left cylinder and right cylinder, racket gripper cylinder 10 is arranged at racket clamping fixture 8 tops.
Wherein, be provided with test/return button, release/clamping button, left and right cylinder switch bar and power switch button on control panel 2.
Left cylinder and right cylinder all are arranged at frame 1 inside.
Locating device 6 comprises base 61 and backstay 62, and the right and left of base 61 is respectively arranged with aperture.
Be provided with aperture on left cylinder and right cylinder.
During concrete the use, at first regulate the clamp distance of racket clamping fixture 8 according to the length of racket, then, racket handle fixture handles 7 is unscrewed, racket handle is passed racket clamping fixture 8 be inserted in the handle fixture, the other end of racket is placed on racket clamping fixture 8.Then screw racket handle fixture handles 7, racket handle is fixed in locating device 6.
Then, the power switch button on control panel 2 is got to the position of " opening ", then will be discharged/the clamping button gets to " clamping " position, the other end of racket compressed.
Then, rotate as required left and right cylinder switch bar.If select the cylinder on the left side to test, steel cable is passed in the aperture on the locating device 6 left cylinders of insertion; As a same reason, if select the cylinder on the right to test, steel cable is walked around in the aperture on the locating device 6 right cylinders of insertion.
Then, the chamber door 13 on frame 1 is opened, can be seen left cylinder, right cylinder and wire rope, then counterweight is hung on wire rope, close upper chamber door 13.
Then, to test/the return button gets to " test " position, at this moment, if wire rope is to insert in the aperture of left cylinder, the left support bar 3 that is connected with left cylinder is because the weight of counterweight moves down, thereby cause the circular arm of force 5 towards the left side to lower swing, pointer 9 just can be indicated the windup-degree of racket on Left Angle rule 11.In like manner, if wire rope is to insert in the aperture of right cylinder, the right support bar 4 that is connected with right cylinder is because the weight of counterweight moves down, thereby causes the circular arm of force 5 towards the right to lower swing, and pointer 9 just can be indicated the windup-degree of racket on right corner degree rule 12.So, complete test.
In a word, the utility model adopts the disk arm of force 5, and because disk rotates howsoever, the arm of force is all the same, can not change because of angle, thereby improve the precision of test; And the utility model can reverse on both sides, thereby avoid only single anti-torsional strength on one side of surveying, can not reflect reliably the problem of the anti-torsional strength of whole racket, and can make design or make the racket person and can effectively grasp the quality of its racket and divide equally intensity.In addition, the utility model can apply fixing torsion on racket handle, and the deformation intensity in the time of therefore can being used for the test racket and being subject to reversing judges the anti-torsional strength of racket whereby.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned implementation method.Therefore the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although this instructions has used some specific terms, these terms do not consist of any restriction to the utility model just for convenience of description.
