Description

Technical Field

[0001] The utility model relates to the technical field of motor base processing, in particular to a horizontal processing fixture used for motor base processing. Background Art

[0002] The motor base mainly needs to process the foot plane, foot hole, outlet plane, outlet hole, eyelet hole, grounding hole and end hole. The processing parts are distributed on the outer periphery and upper and lower end faces of the motor base. At present, a foot milling machine, two radial drills and an outlet milling machine are needed to complete the processing of the motor base. Among them, the foot milling machine is used to complete the processing of the base foot plane and foot hole. A radial drill is used to complete the processing of the base eyelet hole, grounding hole and front end hole. The outlet milling machine is used to complete the processing of the outlet plane. Another radial drill is used to complete the processing of the outlet hole of the base.

[0003] The existing horizontal processing fixture for processing the motor base is usually fixed in the end hole by the bolts on the fixture when in use. The bolts are at the bottom of the fixture, which is inconvenient to twist and the process is complicated, which seriously delays the processing efficiency. In addition, although the existing horizontal processing fixture for processing the motor base has a fixture similar to a centering chuck, in actual use, the fixture is only opened outward from the inside of the motor base and is only fixed by tension. When processing the outlet and the bottom part of the motor base, a force will be applied to the side of the motor base, which often causes the motor base to be skewed and misaligned, seriously affecting the processing accuracy. Therefore, the existing horizontal processing fixture for processing the motor base has the disadvantages of low efficiency and poor fixing effect. Utility Model Content
