Description

Technical Field

[0001] The utility model relates to the technical field of motor production, in particular to a pressure-applying device for fixing a motor shaft core. Background Art

[0002] Servo motors can control speed and position with high accuracy, and can convert voltage signals into torque and speed to drive the controlled object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft.

[0003] The servo motor rotor includes a rotor core, a shaft core and copper wire wrapped around the outside, wherein the shaft core is pressed and clamped into the middle mounting hole of the rotor core by a pressure device. During this process, it is necessary to ensure that the shaft core is pressed vertically downward, and the length of the shaft core extending out of the rotor core needs to be strictly controlled and the size must be uniform. During the pressure process, the rotor core is clamped into a limit ring that matches its size. After processing, the rotor core is difficult to pull out, so auxiliary equipment is needed to facilitate the removal of the rotor core. Utility Model Content

[0008] The limiting assembly limits the rotor core to facilitate the insertion of the shaft core into the installation hole. Pressing down the rocker plate facilitates the lifting ring to be lifted, so that the ejector rod ejects the rotor core in the limiting clamping ring, thereby facilitating the rapid removal of the rotor core after the shaft core is installed.

[0009] In a preferred embodiment of the utility model, a clamping hole cooperating with the ejector rod is opened at the bottom of the limit clamping ring, and the top end of the ejector rod is clamped in the clamping hole at the bottom of the limit clamping ring, and the end thereof is lower than the top of the clamping hole;

[0010] The ejector rod rises and acts on the bottom of the rotor core in the limiting clamp ring, thereby facilitating the ejection of the internal rotor core and loosening it, so as to facilitate the removal work after the processing is completed.

[0011] In a preferred embodiment of the utility model, a clamping shaft is fixedly arranged on the inner side of the connecting frame, a plug hole cooperating with the clamping shaft on the inner side of the connecting frame is opened on the side of the seesaw, and one end of the seesaw is located at the bottom of the lifting ring.

[0012] In a preferred embodiment of the utility model, an observation hole is vertically opened on the side of the pressure tube, and the end of the locking screw contacts the outer side of the adjusting screw;

[0013] The observation hole is mainly used to adjust the height of the internal adjusting screw, so as to confirm the distance from the bottom end of the adjusting screw to the bottom of the contact ring and effectively control the distance from the end of the shaft core to the surface of the rotor core.

[0014] The beneficial effects of the utility model are:

[0015] The motor shaft core is fixed with a pressure device to limit the rotor core and guide the shaft core that needs to be pressurized to ensure that it is pressed vertically downward. The length of the shaft core reserved outside the rotor core can be controlled by adjusting the screw. After the shaft core is pressurized into the inside of the rotor core, the seesaw is pressed down to lift the lifting ring so that the ejector rod ejects the rotor core in the limiting clamping ring, thereby realizing rapid material removal.

The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0023] like Figure 1-5 The shown pressure-applying device for fixing the motor shaft core comprises a processing table 1, a support frame 2, a hydraulic press 3, a pressure-applying device 4 and a limiting assembly 5. The support frame 2 is fixedly arranged on the top of the processing table 1, the hydraulic press 3 is installed on the top of the support frame 2, the pressure-applying device 4 is sleeved on the telescopic end of the hydraulic press 3, the limiting assembly 5 is arranged on the upper surface of the processing table 1, the pressure-applying device 4 comprises a sleeve 41, a pressure tube 42, an adjusting screw 43, a locking screw 44 and a contact ring 45. The sleeve 41 is sleeved on the telescopic end of the hydraulic press 3, the pressure tube 42 is fixedly arranged at the bottom of the sleeve 41, the adjusting screw 43 is arranged on the inner side of the top of the pressure tube 42, the locking screw 44 is arranged on the outer side of the pressure tube 42, and the contact ring 45 is fixedly arranged at the bottom end of the pressure tube 42.

[0024] Specifically, the limiting assembly 5 includes a connecting frame 51, a seesaw 52, ​​a limiting snap ring 53, a fixed tube 54, a lifting ring 55 and an ejector rod 56. The seesaw 52 is movably connected to the connecting frame 51, the fixed tube 54 is fixedly connected to the processing table 1, the limiting snap ring 53 is fixedly arranged on the top of the fixed tube 54, the lifting ring 55 is sleeved on the outside of the limiting snap ring 53, the ejector rod 56 is fixedly arranged on the inner side of the bottom of the lifting ring 55, the bottom of the limiting snap ring 53 is provided with a clamping hole matched with the ejector rod 56, the top of the ejector rod 56 is clamped in the clamping hole at the bottom of the limiting snap ring 53, and its end is lower than the top of the clamping hole, a clamping shaft is fixedly arranged on the inner side of the connecting frame 51, a jack matched with the inner clamping shaft of the connecting frame 51 is opened on the side of the seesaw 52, ​​one end of the seesaw 52 is located at the bottom of the lifting ring 55, an observation hole is vertically opened on the side of the pressing tube 42, and the end of the locking screw 44 contacts the outer side of the adjusting screw 43.

[0025] In this embodiment, the adjusting screw 43 is first adjusted according to the length of the shaft core that needs to extend out of the end of the rotor core. After loosening the locking screw 44, the adjusting screw 43 can be rotated in the pressure tube 42. The distance from the adjusting screw 43 to the bottom of the contact ring 45 can be effectively judged according to the observation hole on the side of the pressure tube 42, thereby confirming the length of the shaft core extending out of the end face of the rotor core. Subsequently, the locking screw 44 is tightened to prevent the position of the adjusting screw 43 from changing during the pressure application process. Subsequently, the rotor core is placed on the inner side of the top of the limiting clamp 53, and one end of the shaft core is clamped into the mounting hole at the top of the rotor core, and the other end is clamped into the bottom of the pressure tube 42. Since the inner diameter of the pressure tube 42 matches the diameter of the shaft core, the pressure tube 42 can be used to guide the shaft core to ensure that the hydraulic press 3 is pressed vertically downward into the rotor core when pressure is applied.

[0026] Furthermore, the hydraulic press 3 applies pressure, and the pressure device 4 is pressed down under the action of the hydraulic press 3, so that the shaft core is inserted into the rotor core until the bottom of the contact ring 45 fits with the upper surface of the rotor core. After the pressure is applied, the rotor core is stuck in the limiting clamp ring 53 and is difficult to remove. At this time, the outer end of the seesaw 52 is pressed down to rotate it around the inner clamping axis of the connecting frame 51 until one end of the seesaw 52 is tilted. Since one end of the seesaw 52 is located at the bottom of the lifting ring 55, the seesaw 52 is pressed down to lift the lifting ring 55, thereby causing the ejection rod 56 to rise, and act on the bottom of the rotor core through the clamping hole at the bottom of the limiting clamp ring 53, thereby ejecting the rotor core, making it easier to remove the material.

[0027] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.
