Description
Technical Field
The utility model relates to a motor manufacturing field, in particular to stator core pressure equipment is with expanding cover.
Background
At present, in the manufacturing process of small and medium-sized motors, the press mounting of stator cores is a very critical process which is difficult to ensure the quality stability and has high labor intensity, and the good quality of the stator cores directly influences the performance and the quality stability of the motors. Especially in the motor production enterprises of various types and small batch. An existing expansion sleeve for press mounting of a stator core is characterized in that a plurality of arc-shaped sheets 11 are enclosed into a barrel shape as shown in figure 1, in order to enable the arc-shaped sheets to protect the barrel shape and enable the upper end and the lower end to contract and expand at a certain distance along the radial direction, spring columns 12 are connected to the inner sides of the arc-shaped sheets 11, and the spring columns 12 which are separated between the two arc-shaped sheets 11 are connected through springs 13.
SUMMERY OF THE UTILITY MODEL
The utility model provides a stator core pressure equipment is with the cover that expands has solved the cover structure complicacy that expands that is used for stator core pressure equipment to use, and the defect of troublesome and inefficiency of production and processing.
The technical scheme of the utility model is realized like this:
stator core pressure equipment is with expanding cover, including upper and lower both ends equal open-ended staving, the upper end of staving is big-end-up's toper opening, the side upper end of staving is even has seted up a plurality of decurrent upward cracks, upward crack does not extend to the side lower extreme of staving, the medial surface and the lateral surface of intercommunication staving crack upward, the side lower extreme of staving is even has seted up a plurality of ascending lower cracks, the lower crack does not extend to the side upper end of staving, the medial surface and the lateral surface of lower crack intercommunication staving, upward crack and lower crack staggered arrangement.
Further, the lower end of the upper slot is an arc-shaped port, and the upper end of the lower slot is an arc-shaped port.
Further, the number of the upper slots and the number of the lower slots are three.
The utility model has the advantages that: the utility model is a whole body, and can keep the barrel shape without foreign objects, and the whole body can realize the contraction and expansion along the radial direction with a certain distance through the upper seam and the lower seam; in addition the utility model discloses simple structure mainly opens on the staving open the seam with under open the seam can, production is simple, production efficiency is high.
