Detailed Description
The present invention will be further described with reference to fig. 1 to 5.
A variable PCD wheel dynamic balancing machine self-positioning device, comprising: the dynamic balancing machine 1 is characterized in that a fixed seat 4 is coaxially arranged at the upper end of a main shaft 2 of the dynamic balancing machine; the rotary table 5 is rotatably arranged in the fixed seat 4 through a bearing 13, the rotary table 5 is coaxial with the fixed seat 4, and N guide holes 11 are uniformly arranged on the rotary table 5 at intervals along the circumferential direction; the rotary table locking device is arranged in the fixed seat 4 and used for locking and fixing the rotary table 5 relative to the fixed seat 4; n location axle 8, set up along the even interval of circumferencial direction as the centre of a circle with the center of carousel 5 respectively, location axle 8 sets up along vertical direction, the number of N is the same with the number in the PCD hole of wheel 3, the lower extreme of location axle 8 is connected with connecting rod 7, the outside end of connecting rod 7 is connected with fixing base 4 is articulated through pivot 6, the lower extreme of connecting rod 7 is provided with slider 12, slider 12 slides the cartridge in the guiding hole 11 that corresponds, when carousel 5 clockwise turning, each location axle 8 is synchronous to the outside and is expanded, wheel 3 is arranged in on fixing base 4, each location axle 8 cartridge respectively in the PCD hole of wheel 3 that corresponds. According to the specification of the wheel 3, the rotary disc 5 is rotated, when the rotary disc 5 rotates clockwise, the sliding blocks 12 slide outwards relatively in the guide holes 11, so that the connecting rods 7 synchronously swing outwards, the positioning shafts 8 synchronously move outwards, the rotary disc 5 is locked and fixed through the rotary disc locking device until the specification of a circle formed by the positioning shafts corresponds to the PCD hole positions of the wheel 3, and the position of the positioning shafts 8 is kept unchanged.
