Description
Technical field
A kind of racket threader is the utility model is related to, especially a kind of tension-adjusting gear of racket threader.
Background technology
Racket threader, is the machine to racket threadings such as tennis racket, racket, wall ball rackets also known as " racket drawing machine "
Device.By taking racket as an example, it is initially threaded with hand, pure to have been manually done, and there are problems with：One is threading time length, separately
Outer one is that the line poundage worn is uneven, does not wear the line of high poundage.The braiding machine to grow up after the nineties applies to plumage
Ball top threads, and solves the problems, such as time and poundage, for example, the tension system application lever principle of weight threader, passes through adjusting
Weight on bar adjusts poundage.Although such tension system poundage is accurate, weight will be made by requiring to thread each time
It is horizontal positioned, certain error otherwise will be produced, this causes the threading speed of weight machine to be limited all the time.Hand-rail type threader uses bullet
Spring tension system, value of thrust is weighed by the deformation quantity of spring, locks head after reaching value of thrust, such design is significantly
The speed of threading is accelerated, and the price of hand-rail type threader can't how much higher than weight machine, thus also have at present very much
Place is still using this hand-rail type threader.Although hand-rail type threader accelerates the speed of threading, but by spring Lai
The threading poundage of measurement, since spring is easy to deform or there are elastic fatigue, causes threading poundage unstable, influences
The use of racket.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of fast automatic threading of auxiliary, and thread poundage accurate stable
Tension-adjusting gear, for racket threading, which adjusts tension force by the distance that Hall switch sensing pull wire head moves, and keeps away
The introducing of elastic system is exempted from.
To solve this technical problem, the utility model takes following scheme：
A kind of tension-adjusting gear of racket threader, including base and the anchoring for being fixed on base one end, it is described
Anchoring include console, be fixed on the controller of the console side, and inside the console
Motor and multiple Hall switch, the console are equipped with the first guide-track groove of hollow out, the control below the guide-track groove
Platform is internally provided with the first screw, and be slidably connected a pull wire head on first screw；
The motor is connected with the second screw, and described second screw one end connects nearly " L " shape connecting plate by nut
One end, the nut both ends are equipped with the connecting plate, and the other end of the connecting plate connects "T"-shaped part, passes through T " the shape parts
It is connected with the pull wire head, magnet is installed on the "T"-shaped part；
The Hall switch is fixedly mounted on the cross bar inside console, and the cross bar is slided with the pull wire head to be connected
Connect；
Start motor, drive connecting plate to be moved axially along the second screw by the second screw, the connecting plate other end is connected
Magnet on "T"-shaped part and the pull wire head being connected with "T"-shaped part correspondingly move, and the Hall switch on cross bar senses magnetic
After body is moved to calibration position, stop motor driving, and then realize the distance moved by Hall switch sensing pull wire head to adjust
Save tension force.
Further, the connecting plate is connected through the console with the "T"-shaped part, described at corresponding connecting plate
Console is equipped with the second guide-track groove, and second guide-track groove is set along the first guide-track groove direction.
Further, the pull wire head bottom is equipped with an elastic component, to protect the Hall switch.
Further, the elastic component is spring or shrapnel.
By using preceding solution, the utility model is adjusted by the distance that Hall switch sensing pull wire head moves
Tension force, avoids poundage wild effect present in spring tension system so that the performance of racket can perfectly be sent out
Wave.
Brief description of the drawings
Fig. 1 is the tension-adjusting gear side view for the racket threader that the utility model embodiment 1 provides；
Fig. 2 is the tension-adjusting gear top view for the racket threader that the utility model embodiment 1 provides.
Embodiment
Technical solutions of the utility model are further elaborated with reference to the accompanying drawings and examples, present embodiment can have
Different form and it is not understood as limited to explanation set forth herein.Identical reference numeral represents identical all the time in text
Element, similar reference numeral represent similar element.
Embodiment 1：
With reference to figure 1 and Fig. 2, the tension-adjusting gear of racket threader includes base 1 and the bracing wire for being fixed on base one end
Device, the anchoring include console 2, are fixed on the controller 3 of 2 side of console, and installed in the control
Motor 4 and 4 Hall switch 5 inside platform 2, the console 3 are equipped with the first guide-track groove 6 of hollow out, first guide rail
The console 3 of the lower section of groove 6 is internally provided with the first screw 7, and be slidably connected a pull wire head 8 on first screw 7, the drawing
8 afterbody of the end of a thread connects "T"-shaped part 9, and magnet 91 is installed on the "T"-shaped part 9.The motor 4 is connected with the second screw 10, institute
One end that 10 one end of the second screw connects nearly " L " shape connecting plate 11 by nut is stated, the nut both ends are equipped with the company
Fishplate bar 11, the other end of the connecting plate 11 are connected with the "T"-shaped part 9.
The Hall switch 5 is fixedly mounted on the cross bar 12 inside console 3, the cross bar 12 and the pull wire head
8 are slidably connected so that pull wire head 8 can slide axially along cross bar 12.
After starting motor 4, motor 4 is rotated drives connecting plate 11 to be moved axially along the second screw 10 by the second screw 10,
11 other end of connecting plate is connected the magnet 91 on "T"-shaped part 9 and correspondingly moved with the pull wire head 8 that "T"-shaped part 9 is connected,
After Hall switch 5 on cross bar 12 senses that magnet 91 is moved to calibration position, stop motor 4 and drive, and then realize by suddenly
The distance that your the sensing pull wire head 8 of switch 5 move adjusts tension force.
Above-mentioned " calibration position " can be installed on the position of "T"-shaped part 9 using device for measuring force in advance, carry out threading poundage
With the corresponding calibration of position, whether position is demarcated by 5 sensor magnet 91 of Hall switch in place after calibration is good, and then correspondingly control
The start and stop of switch.
The quantity of Hall switch is not limited to 4, or 3 or 5, is selected according to the situation of calibration position
Select.
Further, the connecting plate 11 is symmetrically arranged at the both sides of the console 2, and two pieces of connecting plates 11 are connected with nut
