Example (b):

referring to fig. 1 and 2, a grinding running-in mechanism 1 suitable for a potentiometer according to a preferred embodiment of the present invention includes a housing 101, a driving assembly and a transmission assembly. Wherein, be formed with the cavity of its drive assembly of holding in the casing 101 to set up the holding hole that communicates the cavity at the top of casing 101, be used for drive assembly's setting, make the 2 matches of potentiometer to be handled set up behind the top surface of casing 101, potentiometer 2 can correspond with drive assembly and match, and accomplish the grinding running-in of 2 drive mechanism of potentiometer under drive assembly and drive assembly's combination drive.

Specifically, the housing 101 in the preferred embodiment is a box-shaped structure, the top surface of which is horizontally disposed, at least one receiving hole is formed on the top surface, and a plurality of connecting members 106 are disposed on the top surface at intervals around the receiving hole for connecting and fixing the potentiometer 2 on the top surface of the housing 101. In the preferred embodiment, the connecting members 106 are connecting bolts arranged at intervals, and it is understood that the connecting members 106 may be arranged in other forms, such as magnetic attraction, snap, press, etc., as long as reliable fixing of the potentiometer 2 during grinding and running-in process is ensured.

Further, the driving assembly in the preferred embodiment includes actuators 102 disposed in the housing 101, which are disposed in one-to-one correspondence with the receiving holes, and can output the rotating operation process to the outside and correspondingly control the direction, rate, period, etc. of the rotation. In the preferred embodiment, the actuator 102 is a correspondingly arranged servomotor, the output shaft of which is arranged coaxially to the axis of the receiving bore and corresponds to a transmission assembly in the receiving bore, so that the transmission assembly can transmit a transmission torque to the transmission of the potentiometer 2.

In a preferred embodiment, the transmission assembly is as shown in fig. 2, and includes an adapting shaft 103 coaxially embedded in the accommodating hole, one end of the adapting shaft 103 matches with the output end of the driving assembly, and the other end thereof is provided with at least two pin holes 1031, so that at least two positioning pins 201 arranged on the transmission mechanism of the potentiometer 2 can simultaneously match with the pin holes 1031 on the adapting shaft 103, thereby completing the corresponding matching of the transmission mechanism and the transmission assembly and realizing the corresponding transmission of the torque of the driving assembly.

It will be appreciated that in practice, the adapter shaft 103 may be coupled to the output of the drive assembly (e.g., a servo motor) in a variety of alternative ways, such as flange coupling, pin coupling, screw coupling, etc. However, since the above connection is troublesome to replace the adapter shaft 103, in the preferred embodiment, the connection between the adapter shaft 103 and the drive unit is achieved by coaxially matching the non-rotating body boss 1032 with the fitting groove, and the fitting tolerance between the two is more preferably H7/H6.

In specific implementation, the arrangement positions of the non-rotating body boss 1032 and the embedding groove can be interchanged, that is, the arrangement position of the non-rotating body boss 1032 can be at the end of the transfer shaft 103, or at the end of the output end of the transmission assembly, and the embedding groove is the same. Because the non-revolving body boss 1032 is just embedded in the embedding groove, the relative rotation between the transfer shaft 103 and the output end of the transmission assembly cannot occur after the mutual matching. Correspondingly, the other end of the transfer shaft 103 is simultaneously matched with at least two positioning pins 201, so that relative rotation cannot occur between the transfer shaft 103 and the transmission mechanism of the potentiometer 2, only synchronous movement is possible, and thus, reliable transmission of the transmission assembly can be fully ensured.

As shown in fig. 3, the potentiometer 2 in the preferred embodiment is shown in fig. 3 and includes a housing and a gear train disposed within the housing, as well as other components that mate with the gear train. A mounting plate 202 is disposed on one side of the potentiometer 2, and a plurality of connecting holes 203 are preferably formed on the mounting plate 202, so that the potentiometer 2 can be correspondingly fixed on the top surface of the housing 101 after the connecting holes 203 are correspondingly matched with the corresponding connecting members 106. Correspondingly, the transmission mechanism of the potentiometer 2 is provided with at least two positioning pins 201, for example, two positioning pins 201 shown in fig. 3, on a side close to the mounting plate 202, the two positioning pins 201 are arranged in parallel at intervals, one end of each positioning pin is matched with the transmission shaft of the transmission mechanism, and the other end of each positioning pin extends out of the surface of the housing, so that when the mounting plate 202 is correspondingly mounted on the top surface of the housing 101, each positioning pin 201 is respectively matched and embedded in the pin hole 1031 at the top of the adapting shaft 103, and the transmission shaft is rapidly matched with the adapting shaft 103.

Through the corresponding setting of the pin hole 1031 on the end of the transfer shaft 103, the positioning pin 201 on the potentiometer 2 can be effectively utilized, and the grinding running-in of the potentiometer 2 can be quickly completed on the basis.

Further preferably, the casing 101 is further provided with a control box 105 corresponding to the actuator 102, which is connected to the actuator 102 by a cable, and can switch between normal rotation and reverse rotation of the actuator 102, accurately set the number of rotations and rotation speed of the actuator 102, and perform periodic operation according to a certain rule (i.e., determine the execution cycle of the actuator). Therefore, the control parameters of the potentiometer 2 in grinding running-in can be correspondingly changed, the accuracy and the standard of the grinding running-in are ensured, a plurality of potentiometers 2 in the same batch can operate by adopting the same grinding running-in parameters, the accuracy of the production and the assembly of the potentiometers 2 is improved, and the yield is improved.

In a preferred embodiment, the method of use of the abrasive running-in mechanism is preferably as follows:

(1) the setting of the actuating mechanism 102 in the shell 101 and the arrangement of the transmission assembly in the accommodating hole are completed, and the matching of the transmission assembly and the output end of the actuating mechanism 102 is realized; then correspondingly debugging the grinding running-in mechanism to enable the grinding running-in mechanism to be in a state to be operated;

(2) the potentiometer 2 is matched with the connecting piece 106 on the shell 101 through the connecting hole 203 on the mounting plate 202 of the potentiometer, so that the potentiometer 2 is fixed on the shell 101, and at least two positioning pins 201 on the transmission mechanism of the potentiometer 2 are matched into pin holes 1031 on the adapter shaft 103;

(3) setting grinding running-in parameters of the potentiometer 2 in the control box 105, and controlling the execution mechanism 102 to work according to the grinding running-in parameters to drive a transmission mechanism of the potentiometer 2 to grind and run in;

(4) after the potentiometer 2 is completely ground and run in, the actuator 102 is automatically stopped, and then the potentiometer 2 is correspondingly removed from the housing 101 and the next potentiometer 2 is correspondingly replaced.

During actual setting, can prefer simultaneously to be provided with a plurality of holding holes on the same grinding running-in mechanism 1 to be provided with drive assembly and drive assembly respectively, even if must grind running-in mechanism 1 and can realize the grinding running-in of a plurality of potentiometers 2 simultaneously, also perhaps when carrying out the grinding running-in of one of them potentiometers 2, can correspond installation other potentiometers 2 to this practices thrift the grinding running-in time of potentiometers 2, promotes the production efficiency of potentiometers 2.
