Description
Technical field
This utility model belongs to the making field of table tennis, especially relates to a kind of table tennis thickness measure mechanism.
Background technology
Match table tennis has ball weight, diameter and the standard of thickness of clear stipulaties table tennis, making two hemispheres the to be ensured wall thickness of table tennis is equal, and in order to ensure that table tennis has consistent elasticity, its everywhere wall thickness want uniformity, i.e. when the standard ball of table tennis drops down onto table top from 30 centimetres of destage face eminence, bounce amount should be about 23 centimetres.Traditional detection method generally judges generally by artificial experience, and not only cost of labor is high, and degree of accuracy cannot be guaranteed, and affects the quality of final finished.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides and a kind of measures that efficiency is high, accuracy of measurement is high table tennis thickness measure mechanism.
This utility model solves its technical problem and be the technical scheme is that a kind of table tennis thickness measure mechanism, including the support member in dome-type and the mobile bar that is movably connected with support member, the sidewall of described support member is provided with multiple through hole, the top of this support member is provided with baffle plate, the centre of this baffle plate is provided with the perforate running through baffle plate, described mobile bar enters in the hollow cavity of support member at least partially across this perforate, the bottom of described mobile bar is fixedly connected with multiple inductive component, this inductive component includes expansion link, it is located at sensor block and the sensor of expansion link end, described inductive component is distributed in the cavity of support member with the center of support member radially for starting point, sensor block may pass through through hole and table tennis hemisphere contact internal walls to be measured；Described mobile bar is provided with the monitoring center for calculating table tennis hemisphere thickness, and this monitoring center is electrically connected with sensor.
Table tennis hemisphere to be measured is placed in platform, it is positioned at below device, support member moves down the inwall making its outer wall fit in table tennis hemisphere to be measured, mobile bar moves down drive expansion link extruding sensor block, the outer wall of sensor block is contacted with the inwall of table tennis hemisphere, the squeeze pressure that sensor block is subject to by the sensor being located on sensor block is sent to monitoring center, owing to the sensitivity of sensor is higher, when the wall thickness that sensor block touches is thicker, the squeeze pressure that sensor block is subject to is bigger, when the wall thickness that sensor block touches is relatively thin, the squeeze pressure that sensor block is subject to is less, monitoring center can be by calculating the size that squeeze pressure changes into wall thickness, thus the thickness of table tennis hemisphere detected intuitively.
Further, described baffle plate extends formation convex edge laterally, and this convex edge offsets with table tennis hemisphere end face to be measured.This convex edge can offset with platform, it is to avoid device produces too much extruding to table tennis hemisphere and deforms.
Further, described mobile bar connecting dynamic assembly, this Power Component can drive the upper and lower motion of mobile bar.
Further, the outer wall of described sensor block is adaptive with the inwall of table tennis hemisphere.Sensor block is more preferable with the laminating degree of table tennis hemisphere, and avoids it is produced crimp.
The beneficial effects of the utility model are, simple in construction, and automaticity is high, and certainty of measurement is high, and measuring speed is fast, has saved cost of labor.

Detailed description of the invention
In order to make those skilled in the art be better understood from this utility model scheme, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is carried out clear, complete description, obviously, described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all should belong to the scope of this utility model protection.
With reference to shown in Fig. 1-3, a kind of table tennis thickness measure mechanism, including support member 1 and mobile bar 2, mobile bar 2 is movably connected in the top of support member 1 by connector.Support member 1 is in hollow hemisphere type structure, it is internally formed dome-type cavity 13, multiple through hole 11 is offered on the curved wall of support member 1, the top of support member 1 is provided with baffle plate 12, the upper opening of cavity 13 is hidden by this baffle plate 12, and baffle plate 12 circumferentially extending have protrude from the convex edge 122 that cavity 13 is arranged.The centre of baffle plate 12 is provided with the perforate 121 running through baffle plate 12, mobile bar 2 can pass in and out in cavity 13 through this perforate 121, the bottom of mobile bar 2 is fixedly connected with multiple inductive component, inductive component includes expansion link 31, sensor block 32 and sensor, one end of expansion link 31 is connected on mobile bar 2, the other end of expansion link 31 connects sensor block 32, and the outer wall of sensor block 32 has suitable cambered structure with the inwall of table tennis hemisphere 4, and sensor block 32 can protrude from support member 1 through through hole 11.Multiple inductive components, centered by the centre of sphere of support member 1, are distributed in the dome-type cavity 13 of bracing frame 1 radially.
The top of mobile bar 2 connects a Power Component, and this Power Component can drive the upper and lower motion of moving member 2 at a certain time interval.Mobile bar 2 is provided with monitoring center 21, and monitoring center 21 includes computing module, and the pressure that sensor is experienced can be converted into the wall thickness data of table tennis hemisphere 4 by this computing module, and this monitoring center 21 is electrically connected respectively with each sensor.
Operation principle of the present utility model is, table tennis hemisphere 4 to be measured is placed on and has and on the platform of table tennis hemisphere 4 outer wall adaptation groove, support member 1 is placed in table tennis hemisphere 4, bottom surface, convex edge 122 offsets with the end face of table tennis hemisphere 4, the outer wall of support member 1 matches with the inwall of table tennis hemisphere 4, open Power Component, mobile bar 2 through through hole 11 move down drive expansion link 31 outwardly against, sensor block 32 protrudes from the inwall of support member 1 extruding table tennis hemisphere 4 through through hole 11, owing to the thickness of table tennis hemisphere 4 is the most different, the squeeze pressure that sensor block 32 is subject to varies in size, the sensor being electrically connected with each sensor block 32 respectively by the pressure conduction experienced to monitoring center 21, by computing module, squeeze pressure changed into wall thickness numerical value, complete the measurement of table tennis hemisphere 4 thickness.
