Description

Technical Field

[0001] The utility model relates to the technical field of commutator processing equipment, in particular to a commutator production clamping tool. Background Art

[0002] The commutator, commonly known as the rectifier, is a component of a DC permanent magnet series-excited motor that allows the motor to continue rotating. Structurally, the commutator is a circular shape formed by several contact plates, which are connected to each tap on the rotor respectively. Two electrodes called brushes are connected to the outside to contact them, and only two of them are contacted at the same time. Without the function of the commutator, the motor will get stuck before half a circle and can only be used as an electric brake. The centrifugal force generated by the rotation of the motor is used as power to control the size of the starting resistance, so as to reduce the starting current of the motor, increase the starting torque, and enable the wound asynchronous motor to achieve brushless automatic operation. During the production process of the commutator, a grinding device is required to grind the burrs on the surface of the commutator.

[0003] For example, publication number CN212043895U discloses a new type of multifunctional commutator processing equipment, including a machine body, a partition net, a power plug board and a control panel are provided on the top plate of the machine body, a fixing plate is provided on the partition net, a first lifting column and a second lifting column are provided on both sides of the top plate of the machine body, a collection box is provided at the side end of the machine body, the collection box is embedded in the machine body, and a support plate is provided at the bottom of the machine body. This grinding table adopts a ring body clamping form, which occupies a small area. The commutator is driven to flip by a motor, which simplifies the grinding method of the commutator. A pulley and a support plate are provided at the bottom of the machine body. When grinding, the support plate provides support for the entire machine body, which can ensure the stability of the machine body and will not be affected by external forces. The waste generated during the grinding process will directly fall into the partition net and be uniformly processed through the collection box, effectively avoiding the problems of heavy workload and long time caused by manual cleaning.

[0004] Based on the search of patent numbers and combined with the deficiencies in the prior art, it is found that:
