In the present embodiment, there are the positioning region 33 for being located at 31 top of shell, positioning region 33 is in the form of slot at lock chamber 32 edge,
Its width is just identical as the connecting rod of mounting base 72.
In the present embodiment, 32 wall surface of lock chamber is covered with the ceramic wearing coat of spraying, to avoid ball pin 71 and lock chamber
32 interference damages.
In the present embodiment, electronic control module is also connected with display 43.
Fig. 1,2 are please referred to, in the assembly test device work of this spiral, firstly, assembler fills the bulb of ball pin 71
In the ball-and-socket for entering mounting base 72, meanwhile, a trundle 531 is inserted into pin hole 711.Hereafter, the ball pin 71 that will be completed
It is put into lock chamber 32 with mounting base 72, in the upper end of lock chamber 32, the connecting rod of mounting base 72 is embedded in positioning region 33, thus
Fixation when installing top cover 73 in subsequent assembly is realized in limit, while being convenient for the positioning of assembler；In the lower end of lock chamber 32,
In the rotation slot of the bottom insertion driving section 53 of ball pin 71, while the also insertion just of its trundle 531 for passing through pin hole 711.This
Afterwards, assembler starts test device by the switch of electronic control module, and test motor 42 drives torductor 41 to rotate, torque
The rotation of measuring instrument 41 is converted into driving section 53 by the cone tooth of first gear 51 and second gear 52 commutation in reversing arrangement
Horizontally rotate, driving section 53 drives chimeric trundle 531 in the inner by its rotation slot and finally ball pin 71 driven to install
It is rotated under the limitation of 72 ball-and-sockets of seat, the torsion that the active force for the spring 74 that ball pin 71 fills after overcoming under the rotary action starts turning
Square is its driving torque, which changes with the pressure and degree of spring 74.Meanwhile assembler is successively by spring 74 and top cover 73
In the pre- upper end opening for being mounted in mounting base 72.Hereafter, assembler operates mounting device 2 and falls, until the convex ridge of mounting portion 23
Mutually chimeric with the groove of top cover 73, assembler starts installation motor 22, and installation motor 22 drives mounting portion 23 to rotate, formed
The movement of screw thread is tightened, top cover 73 is to be screwed into mounting base 72 to realize the installation automated, while being screwed into top cover 73, spring
74 apply elastic force by pressure and to ball pin 71.As spring 74 applies elastic force, i.e. spring 74 and mounting base 72 to ball pin 71
Ball-and-socket the frictional resistance of the bulb of ball pin 71 is increased, driving torque needed for ball pin 71 overcomes the frictional resistance increases,
This torque i.e. detected by torductor 41, when torductor 41 detect driving torque reach design value when,
Electronic control module controls mounting device 2, test device shuts down and completes installation, at this time the mechanics parameter of the ball pin assembly of output,
In particular driving torque is required numerical value, has the advantages that accuracy height, high degree of automation, without subsequent detection.This
Afterwards, assembler operates mounting device 2 and rises, and ball pin assembly is taken out, what each device can be assembled next time after resetting
Circulation.During the work time, the first displacement coder 61 and the second displacement coder 62 can be by torductors 41 and peace
The phase angular dimensions that dress motor 22 rotates is delivered to electronic control module, and when device resets, test motor 42 and installation motor 22 are in electricity
It controls to pass through to rotate under the control of module and the phase position of rotation section 53 and mounting portion 33 is returned back into original state, is i.e. assembly every time
Each position before beginning is all determining and constant, convenient for the positioning of operator, can effectively improve production efficiency.Meanwhile being
It prevents mounting device 2 from damaging screw thread to the over-tightened of top cover 73, in production, the overload of torque force limiting device 24 can be set
Value, after the installation torque of screw thread exceeds overload values, friction plate, which starts to skid, is not transferred to peace for the rotation for installing motor 22
Dress portion 23, to carry out effective screw thread protection.
Only preferred embodiments of the present invention will be described for above embodiments, not to the spirit and scope of the present invention
It is defined, without departing from the design concept of the invention, ordinary people in the field makes technical solution of the present invention
All variations and modifications, each fall within protection scope of the present invention, the claimed technology contents of the present invention, whole note
It carries in detail in the claims.
