n location axle, the even interval setting of circumferencial direction of circle center edge with the center of carousel respectively, the location axle sets up along vertical direction, and the number of N is the same with the number in the PCD hole of wheel, and the lower extreme of location axle is connected with the connecting rod, the outside end of connecting rod is connected with the fixing base is articulated through the pivot, the lower extreme of connecting rod is provided with the slider, the slider slides the cartridge in the guiding hole that corresponds, and when the carousel clockwise rotation, each location axle is synchronous to be expanded to the outside, and the wheel is arranged in on the fixing base, and each location axle cartridge respectively is in the PCD hole of the wheel that corresponds.

Furthermore, above-mentioned carousel locking device sets up in the fixing base and coaxial the screw rod that sets up in the through-hole including setting up the through-hole in the carousel and along vertical direction, and on the nut screwed on the screw rod, the lower terminal surface of nut contacted with the up end of carousel, the through-hole is coaxial with the carousel mutually.

The utility model has the advantages that: when the turntable rotates clockwise, the sliding blocks slide outwards in the guide holes relatively, so that the connecting rods synchronously swing outwards, the positioning shafts synchronously move outwards, the turntable is locked and fixed through the turntable locking device until the specification of a circle formed by the positioning shafts corresponds to the PCD hole positions of the wheels, and the positions of the positioning shafts are kept unchanged. After the wheels are placed on the fixed seats, the positioning shafts are inserted into the PCD holes of the corresponding wheels to position the wheels, and then the dynamic balancing machine starts to drive the fixed seats to drive the wheels to rotate, so that dynamic balance testing is performed. In a similar way, when the reverse rotation carousel, each location axle moves to the inboard in step, conveniently adjusts the PCD size to the wheel of different specifications, has improved the production efficiency of wheel.

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.
