Abstract
The utility model relates to a laser-assisted positioning electronic measuring tape of a dynamic wheel balancer, which relates to an electronic measuring tape of a dynamic wheel balancer. The dynamic wheel balancer can be used for assisting the sticking of the electronic measuring tape of a balanced block and help solve the problem that the length of a rotating rod at a tape head restricts the work of the electronic measuring tape when the electronic measuring tape is used for measuring the diameter of a wheel. Two ends of a tape rod are fixedly connected with the tape head and a first potentiometer. A first laser tube protecting sleeve is fixedly arranged in the tape head. A spotted laser tube is fixedly arranged in the first laser tube protecting sleeve. The tape rod is fixedly connected with a first drawing wire by a drawing wire bracket. The first drawing wire is wound on a potentiometer wheel after extending past a steering wheel. The potentiometer wheel is fixedly connected with a second potentiometer. One end of a second drawing wire is wound on a potentiometer wheel, and the other end thereof is fixedly connected with a pull spring. A horizontal-line-type laser tube is fixedly arranged on a laser tube fixing seat. An electromagnet is fixedly connected with a machine case by an electromagnet fixing bracket. The electromagnet is provided with a friction block. When the electronic measuring tape is used for measuring the size of a cone body at the inner side of a wheel rim, the measurement is free from the restriction of the diameter of the wheel. When the balanced block is stuck, light spots generated by the laser tube are utilized for indicating the position of an unbalanced block.
