Description

TECHNICAL FIELD

[0001] The utility model belongs to motor rotor slotting technical field, concretely relates to a kind of positioning device for motor rotor slotting. BACKGROUND

[0002] Motor rotor is a key component in motor, and it is the core component of motor with stator, and in the process of motor operation, rotor is responsible for the conversion between mechanical energy and electrical energy, currently, motor rotor needs to use special positioning device for motor rotor slotting when producing, to process it;

[0003] The existing positioning device for motor rotor slotting usually relies on the triangular chuck and the top column of the traditional lathe to fix the rotor. Although this method can achieve the fixation of the motor rotor to some extent, there are still some problems in actual operation. Since the motor rotor will be subjected to axial pressure during slotting, this unilateral stress condition is easy to cause the rotor to deviate axially or even to separate, thereby affecting its stability. SUMMARY

[0004] Therefore, the utility model provides a positioning device for motor rotor slotting, which can adaptively support motor rotors of different diameters through the cooperation of the supporting mechanism, the moving assembly and the driving assembly, enhance the axial support stiffness of the motor rotor, completely eliminate the risk of axial deviation or separation caused by unilateral stress during slotting, and keep the rotor in a stable state during slotting.

[0005] To solve the above technical problems, the utility model provides a positioning device for motor rotor slotting, which includes a slotting machine and a supporting mechanism arranged at the upper end of the slotting machine. The supporting mechanism includes guide rods symmetrically arranged at both sides of the upper end of the slotting machine. Two guide rods at the same end are both connected with arc-shaped guide plates through sliding. The middle part of the opposite inner side surface of the two arc-shaped guide plates is provided with a linear guide rail. The linear guide rail is connected with a linear guide plate through sliding. Two adjusting rods are movably arranged at both sides of the two arc-shaped guide plates. The middle part of the adjusting rod is rotatably connected with a rotating sleeve. The two ends of the linear guide plate are respectively connected with one end of the adjacent adjusting rod on the same side through sliding. The slotting machine is provided with a moving assembly for driving the arc-shaped guide plates to move synchronously up and down. The linear guide rail is provided with a driving assembly for driving the linear guide plate to move up and down. The positioning device can adaptively support motor rotors of different diameters, enhance the axial support stiffness of the motor rotor, completely eliminate the risk of axial deviation or separation caused by unilateral stress during slotting, keep the rotor in a stable state during slotting, and be suitable for the rapid switching processing of rotors of various specifications, thereby significantly improving the production efficiency and processing consistency.

[0006] The moving component includes fixed plates respectively set at both ends of the grooving machine. Both ends of the upper part of the grooving machine are rotatably connected to the fixed plates on the same side. The screws are threadedly connected to the screw holes set in the middle of the adjacent arc-shaped guide plates on the same side, thereby driving the arc-shaped guide plates and their auxiliary mechanisms to move vertically.

[0007] The moving component also includes mounting cavities located at the upper end of the grooving machine near the lower end of each lead screw. Each mounting cavity is equipped with a motor, and the output shaft of the motor is fixedly connected to the adjacent lead screw on the same side, thus providing a drive source for the lead screw.

[0008] The drive assembly includes threaded rods that are rotatably connected to the linear guide rails. The threaded rods are threadedly connected to threaded holes in the middle of the adjacent linear guide plates on the same side, thus serving as the drive mechanism.

[0009] The drive assembly also includes a second motor, which is respectively located at one end of the linear guide rail. The output shaft of the second motor is fixedly connected to one end of the adjacent threaded rod on the same side, thus providing a drive source for the threaded rod.

[0010] Both of the inner sides of the two arc-shaped guide plates are equipped with baffles to prevent machining debris from splashing.

[0011] The baffles are all angled downwards from the outside in, which guides the debris to slide off.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. First, the operator fixes the motor rotor to be slotted onto the slotting machine. Then, according to the size of the motor rotor to be slotted, the moving component and the drive component are started in sequence, thereby driving the arc-shaped guide plate to rise and fall synchronously along the guide rod, and at the same time pushing the linear guide plate to move vertically along the linear guide rail. During the movement of the linear guide plate, the adjusting rod will be affected by the combined force of the arc-shaped guide plate and the linear guide plate, thus changing its position. This adaptively supports motor rotors of different diameters, enhances the axial support rigidity of the motor rotor, and completely eliminates the risk of axial displacement or separation caused by unilateral force during the slotting process. This ensures that the rotor is always in a stable state during slotting. It is also suitable for the rapid switching of processing of rotors of various specifications, significantly improving production efficiency and processing consistency. At the same time, the inclined design of the baffle plate can both block the splashing of processing debris and guide the debris to slide outward.

[0014] 2. The rotation of the motor's output shaft drives the lead screw to rotate. When the lead screw rotates, it drives the arc-shaped guide plate to rise and fall synchronously along the guide rod, thereby driving the arc-shaped guide plate and its auxiliary mechanisms to move vertically.

[0015] 3. The rotation of the motor's second output shaft drives the threaded rod to rotate synchronously. When the threaded rod rotates synchronously, it pushes the linear guide plate to move vertically along the linear guide rail, providing a driving source for the threaded rod.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figures 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] This embodiment provides a positioning device for slotting motor rotors, such as... Figures 1-4The diagram shows a grooving machine 100 and a support mechanism mounted on its upper end. The grooving machine 100 is a machine tool. The support mechanism includes guide rods 200 symmetrically arranged on both sides of the upper end of the grooving machine 100. Arc-shaped guide plates 201 are slidably connected between the two guide rods 200 at the same end. Linear guide rails 202 are provided in the middle of the opposite inner surfaces of the two arc-shaped guide plates 201. The linear guide rails 202 are perpendicular to the arc-shaped guide plates 201. Linear guide plates 203 are slidably connected within each linear guide rail 202. Adjusting rods 204 are movably arranged on both sides between the guide plates 201. The two ends of the adjusting rods 204 are respectively located in the adjacent arc-shaped guide plates 201 on the same side. The middle of the adjusting rods 204 is rotatably connected to the rotating sleeves 205. The two ends of the linear guide plates 203 are respectively slidably engaged with one end of the adjacent adjusting rods 204 on the same side. The grooving machine 100 is equipped with a moving component for driving the arc-shaped guide plates 201 to move up and down synchronously. The linear guide rail 202 is equipped with a driving component for driving the linear guide plates 203 to move up and down.

[0024] First, the operator fixes the motor rotor to be slotted onto the slotting machine 100. Then, according to the size of the motor rotor to be slotted, the moving component and the driving component are activated in sequence, thereby driving the arc-shaped guide plate 201 to rise and fall synchronously along the guide rod 200, and at the same time pushing the linear guide plate 203 to move vertically along the linear guide rail 202. During the movement of the linear guide plate 203, the adjusting rod 204 will be subjected to the combined force of the arc-shaped guide plate 201 and the linear guide plate 203, and its position will change, thereby adaptively supporting motor rotors of different diameters, enhancing the axial support rigidity of the motor rotor, and completely eliminating the risk of axial displacement or separation caused by unilateral force during the slotting process. This ensures that the rotor is always in a stable state during slotting, and is suitable for rapid switching processing of rotors of various specifications, significantly improving production efficiency and processing consistency. At the same time, the inclined design of the baffle plate 500 can both block the splashing of processing debris and guide the debris to slide outward.

[0025] like Figures 1-4 As shown, the moving assembly includes fixed plates 300 respectively disposed at both ends of the grooving machine 100. Both ends of the upper part of the grooving machine 100 are rotatably connected to the fixed plates 300 on the same side. Both ends of the upper part of the grooving machine 100 are provided with rotating grooves for providing rotational support for the lead screws 301 between the fixed plates 300 on the same side. The lead screws 301 are threadedly connected to the threaded holes provided in the middle of the arc-shaped guide plates 201 on the same side. The moving assembly also includes mounting cavities respectively disposed at the upper end of the grooving machine 100 near the lower end of each lead screw 301. Each mounting cavity is provided with a motor 302. The output shaft of the motor 302 is fixedly connected to the lead screw 301 on the same side.

[0026] The output shaft of motor 302 rotates to drive the lead screw 301 to rotate. When the lead screw 301 rotates, it drives the arc-shaped guide plate 201 to rise and fall synchronously along the guide rod 200, thereby driving the arc-shaped guide plate 201 and its auxiliary mechanism to move vertically.

[0027] like Figures 1-4 As shown, the drive assembly includes threaded rods 400 rotatably connected to linear guide rails 202. A rotating hole is provided between the upper and lower ends of the inner cavity of linear guide rails 202 to provide rotational support for the threaded rods 400. The threaded rods 400 are threadedly connected to threaded holes provided in the middle of adjacent linear guide plates 203 on the same side. The drive assembly also includes a second motor 401 respectively provided at one end of linear guide rails 202. The output shaft of the second motor 401 is fixedly connected to one end of the adjacent threaded rods 400 on the same side.

[0028] The output shaft of motor 401 rotates to drive the threaded rod 400 to rotate synchronously. When the threaded rod 400 rotates synchronously, it pushes the linear guide plate 203 to move vertically along the linear guide rail 202, providing a driving source for the threaded rod 400.

[0029] like Figure 1 As shown, the upper ends of the opposite inner sides of the two arc-shaped guide plates 201 are provided with baffles 500. The baffles 500 are inclined downward from the outside to the inside. The inclined design of the baffles 500 can both block the splashing of processing debris and guide the debris to slide down.

[0030] The working principle of the positioning device for slotting a motor rotor provided by this utility model is as follows: First, the operator fixes the motor rotor to be slotted onto the slotting machine 100. Then, according to the size of the motor rotor to be slotted, the operator starts motor one 302 and motor two 401 in sequence. The output shaft of motor one 302 rotates, driving the lead screw 301 to rotate. When the lead screw 301 rotates, it drives the arc-shaped guide plate 201 to rise and fall synchronously along the guide rod 200. At the same time, the output shaft of motor two 401 rotates, driving the threaded rod 400 to rotate synchronously. When the threaded rod 400 rotates synchronously, it pushes the linear guide plate 203 to move vertically along the linear guide rail 202. During the movement of the linear guide plate 203, the adjusting rod 204 will be subjected to the combined force of the arc guide plate 201 and the linear guide plate 203, thereby changing its position. This adaptively supports motor rotors of different diameters, enhances the axial support stiffness of the motor rotor, and completely eliminates the risk of axial displacement or separation caused by unilateral force during grooving. This ensures that the rotor remains stable during grooving and is suitable for rapid switching of rotors of various specifications, significantly improving production efficiency and processing consistency. At the same time, the inclined design of the baffle plate 500 can both block the splashing of processing debris and guide the debris to slide outward.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
