Description

Technical Field

[0001] The utility model belongs to the technical field of winding stator assembly equipment, in particular to a winding stator assembly pressing device. Background Art

[0002] After the winding stator assembly parts are assembled, they need to be pressed with a hydraulic press. The hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes.

[0003] Since conventional hydraulic presses use one-handed operation to press down, it is easy to make the wrong operation mode of holding one hand on the product and pressing down with the other hand, which may cause the hand to be easily crushed. In addition, the adjustment of the downward pressure amplitude of the hydraulic press also requires the use of a screwdriver to screw multiple screws to adjust, resulting in the problem of poor practicality of conventional hydraulic equipment for winding stator assembly.

[0004] To this end, we propose a winding stator assembly clamping device to solve the above problems. Utility Model Content

Pressing the two start switches with both hands at the same time drives the hydraulic press to press down, effectively avoiding the accident of one hand pressing the other hand; during the pressing process, the pressure is sensed by the pressure sensor, and the pressure is analyzed by the intelligent device to control and stop the hydraulic press pressing drive to protect the stator; the threaded knob is loosened to loosen the lifting seat, and then the height of the lifting seat is adjusted, and the height of the limit switch is adjusted by the lifting seat, and then the threaded knob is tightened. When the limit switch is squeezed during the pressing process of the hydraulic press, the limit switch is used to disconnect the hydraulic press pressing drive, which is convenient for adjusting the pressing range of the hydraulic press, and further improves the safety factor of the hydraulic press.

[0008] Preferably, a scale is provided on the side of the hydraulic press, the lower end of the scale is fixedly connected to the hydraulic press, and the lifting seat is in movable contact with the scale. When adjusting the height of the lifting seat, the height parameters of the lifting seat can be conveniently observed through the scale of the scale.

[0010] Preferably, the lifting seat further comprises a pointer, and the pointer is fixedly connected to the seat body. The pointer is used to point to the scale of the scale, so as to facilitate observation of the specific scale.

[0011] Preferably, the nut includes a threaded block and a spring, one end of the spring is fixedly connected to the threaded block. After the threaded knob is loosened, the threaded block acts on the seat body through the spring, so that the lifting seat and the hydraulic press maintain a certain friction force, which is convenient for preventing the lifting seat from accidentally sliding down during adjustment.

[0012] Preferably, the threaded knob comprises a knob and a bolt, wherein the bolt is symmetrically fixedly connected to the outer end of the knob. Twisting the knob drives the bolt to rotate, and the two nuts are tightened or loosened through the bolt.

When the hydraulic press is in the process of pressing down, the power-off switch is used to disconnect the pressing driving power supply of the hydraulic press, so as to conveniently control the pressing amplitude of the hydraulic press.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Press the two start switches with both hands at the same time to drive the hydraulic press to work downward, effectively avoiding the accident of one-handed operation pressing the other hand; during the downward process, use the pressure sensor to sense the pressure, analyze the pressure through the intelligent device, control and shut down the downward drive of the hydraulic press to protect the stator; loosen the threaded knob to loosen the lifting seat, then adjust the height of the lifting seat, adjust the height of the limit switch through the lifting seat, and then tighten the threaded knob.
