Description

Technical Field

[0001] This utility model relates to the field of motor shaft machining technology, specifically a cutting device for machining motor shafts. Background Technology

[0002] As a transmission component that enables the conversion of electrical energy into mechanical energy, the machining accuracy of the motor shaft directly determines the stability of the motor's power output, transmission efficiency, and service life. It is widely applicable to diverse fields such as industrial drives, new energy vehicles, home appliances, and aerospace.

[0003] Reference patent document: Patent publication number CN215545310U, patent publication date 2022-01-18, discloses a cutting device for machining motor shafts, including a machine tool. One side wall of the machine tool is rotatably connected to a first clamping plate unit. A cutting unit is provided on one side of the first clamping plate unit. An adjustable center unit is fixedly installed at the top of one side of the machine tool. The motor shaft is placed between the first clamping plate unit and the adjustable center unit. The clamping plate in the first clamping plate unit and the center in the adjustable center unit are fixed to the motor shaft by the control button on the machine tool. The first motor, the second electric telescopic rod and the second motor in the cutting unit cause the circular blade to cut the outer wall of the motor shaft. At the same time, the third motor in the adjustable center unit drives the motor shaft to rotate, thereby automatically adjusting and cutting the motor shaft.

[0004] Although the aforementioned patent solves the problem of manual hand-held processing through the clamping unit, in the case of machining the motor shaft, where the workpiece needs to rotate and move axially simultaneously, it requires multiple manual interventions to adjust the angle of the motor shaft, which reduces processing efficiency. In addition, a large amount of debris is generated during cutting, which usually falls directly onto the machining table, forcing the machine to be stopped for cleaning and processing to resume after a period of time. If the accumulated debris enters the guide rails, bearings and other moving parts of the equipment, it will affect the service life of the equipment.

[0005] Therefore, this utility model provides a cutting device for machining motor shafts. Utility Model Content

[0006] To address the inefficiencies caused by manual adjustment of workpiece angles during complex cutting operations, and the lack of effective online chip removal, this invention aims to provide a cutting device for motor shaft machining.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for machining motor shafts, comprising a machining table, two symmetrically distributed machine bases fixedly mounted at the bottom of the machining table, a mounting frame fixedly mounted on one side of the top of the machining table, a cutting device mounted in the middle of the mounting frame, and a cutting mechanism provided on the upper part of the machining table for cutting the motor shaft. The cutting mechanism includes: The adjustment assembly includes a cylinder fixedly installed in the middle of one side of the mounting bracket, a sliding frame slidably provided on one side of the top of the processing table, a three-jaw chuck rotatably installed on one side of the sliding frame, a rotating shaft fixedly installed in the middle of one end of the three-jaw chuck, a fixed frame fixedly installed on one side of the top of the processing table, a driven gear rotatably installed in the middle of the fixed frame, a drive assembly provided on one side of the driven gear, a connecting plate fixedly installed on the drive end of the cylinder, and one end of the rotating shaft rotatably installed in the middle of one side of the connecting plate. The cleaning component, located at the bottom of the machining table, is used to collect waste generated during cutting.

[0008] Preferably, the cleaning assembly includes a vacuum cleaner fixedly installed on one side of the bottom of the mounting frame, a plurality of equally spaced sliding grooves are provided on the upper part of the processing table, the lower part of the sliding frame is slidably locked in the middle of the sliding grooves, a vacuum pipe is fixedly installed on one side of the processing table, the vacuum pipe is connected to the sliding grooves, and the other end of the vacuum pipe is fixedly installed on the drive end of the vacuum cleaner.

[0009] Preferably, the drive assembly includes a motor frame fixedly mounted on one side of the fixed frame, a drive motor fixedly mounted on the top of the motor frame, a drive gear fixedly mounted on the drive end of the drive motor, and the drive gear and the driven gear meshing with each other.

[0013] Beneficial effects This invention provides a cutting device for machining motor shafts. Compared with the prior art, it has the following advantages: 1. This application can use the set adjustment component to drive the connecting plate with the cylinder, thereby driving the rotating shaft and sliding frame to move axially. At the same time, the drive motor transmits the rotational power to the rotating shaft and the three-jaw chuck through the meshing of the drive gear and the sliding fit between the drive block and the waist-shaped hole. This allows the workpiece to be rotated by the three-jaw chuck for circumferential cutting while also being precisely fed axially. The two work together to make the cutting process of the motor shaft continuous, stable and efficient, significantly improving the processing efficiency and processing quality.

[0014] 2. During the cutting process, the metal chips generated fall onto the surface of the machining table and are guided into the chute by a triangular guide block. Subsequently, the vacuum cleaner is activated and quickly sucks the waste chips collected in the chute into the dust collection bin through the suction pipe. This enables automatic and centralized collection and cleaning of waste chips, effectively avoiding the impact of waste chip accumulation on machining accuracy and equipment operation, while maintaining a clean working environment and reducing the burden of manual cleaning.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a cutting device for machining motor shafts, including a machining table 11. Two symmetrically distributed machine bases 1 are fixedly mounted on the bottom end of the machining table 11. The machine bases 1 are welded structures made of Q235 steel, and the center distance between the two machine bases 1 is 1200mm to ensure the stability of the device during operation. A mounting bracket 12 is fixedly mounted on one side of the top of the machining table 11. A cutting device 13 is mounted in the middle of the mounting bracket 12. The cutting device 13 uses a CNC carbide milling head, model XK7132. A cutting mechanism 2 is provided on the upper part of the machining table 11 for cutting the motor shaft. The cutting mechanism 2 includes: The adjustment assembly 21 includes a cylinder 211 fixedly installed in the middle of one side of the mounting bracket 12. The cylinder 211 is a standard SC63×200 cylinder, which can drive the workpiece to achieve axial feed movement. A sliding frame 2181 is slidably provided on one side of the top of the machining table 11. A three-jaw chuck 218 is rotatably installed on one side of the sliding frame 2181. The three-jaw chuck 218 is a K11250 self-centering chuck. A rotating shaft 217 is fixedly installed in the middle of one end of the three-jaw chuck 218. A fixing bracket 215 is fixedly installed on one side of the top of the machining table 11. A driven gear 2161 is rotatably mounted in the middle of the fixed frame 215. A drive assembly is provided on one side of the driven gear 2161. A connecting plate 212 is fixedly mounted on the drive end of the cylinder 211. One end of the rotating shaft 217 is rotatably mounted in the middle of one side of the connecting plate 212. The cylinder 211 drives the connecting plate 212 to move the rotating shaft 217, thereby pushing or pulling the sliding frame 2181 to move. This, in turn, drives the three-jaw chuck 218 holding the motor shaft to move axially, thereby adjusting the horizontal position of the motor shaft. The cleaning component 22 is located at the lower part of the machining table 11 and is used to collect waste generated during cutting.

[0022] The cleaning component 22 includes a vacuum cleaner 224 fixedly installed on one side of the bottom of the mounting bracket 12. The vacuum cleaner 224 is a CV-100 industrial vacuum cleaner, equipped with a 10L capacity dust collection bin, which can achieve continuous operation. The upper part of the processing table 11 has multiple equally spaced slide grooves 221. The lower part of the sliding frame 2181 is slidably locked in the middle of the slide groove 221. A suction pipe 223 is fixedly installed on one side of the processing table 11. The suction pipe 223 is connected to the slide groove 221. The other end of the suction pipe 223 is fixedly installed on the drive end of the vacuum cleaner 224. When cutting generates waste chips, they will fall into the slide groove 221. At this time, the vacuum cleaner 224 works and sucks the waste chips that have fallen into the slide groove 221 into the dust collection bin through the suction pipe 223 for collection.

[0023] The drive assembly includes a motor frame 213 fixedly mounted on one side of the fixed frame 215. The motor frame 213 is an L-shaped steel structure. A drive motor 214 is fixedly mounted on the top of the motor frame 213. The drive motor 214 is a Y100L-2 type three-phase asynchronous motor. A drive gear 216 is fixedly mounted on the drive end of the drive motor 214. The drive gear 216 and the driven gear 2161 are meshed and connected to each other.

[0024] Two symmetrically distributed drive blocks 2171 are fixedly installed on the outer side of the rotating shaft 217. Both drive blocks 2171 are slidably locked in the middle of the driven gear 2161. The middle of the driven gear 2161 has an oblong hole that mates with the drive blocks 2171. When the cylinder 211 pushes the rotating shaft 217 to move axially, the drive blocks 2171 can slide in the oblong hole. At the same time, the torque is transmitted through the keyway to ensure that the rotating shaft 217 can rotate synchronously while moving.

[0025] Multiple guide blocks 222 are fixedly installed at the top of the processing table 11. The cross-section of the multiple guide blocks 222 is triangular, and the guide blocks 222 can guide the falling debris into the slide groove 221 for easy removal.

[0026] A baffle 225 is fixedly installed on one side of the top of the processing table 11. The height of the baffle 225 is two-thirds of the height of the three-jaw chuck 218. The height setting of the baffle 225 can cover the debris while making it convenient for the operator to fix the motor shaft to one side of the three-jaw chuck 218.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] During operation, in the machining process of the motor shaft, the workpiece to be machined is first clamped and fixed by the three-jaw chuck 218. After the device is started, the drive motor 214 starts to work, driving the drive gear 216 at its output end to rotate. The drive gear 216 meshes with the driven gear 2161 rotatably mounted on the fixed frame 215, thereby transmitting power to the driven gear 2161. Since one end of the rotating shaft 217 slides with the waist-shaped hole in the middle of the driven gear 2161 through the drive block 2171, it can allow axial movement while transmitting torque. Therefore, the rotation of the driven gear 2161 can drive the rotating shaft 217 and the three-jaw chuck 218 to rotate together, realizing the circumferential cutting motion of the workpiece. At the same time, the cylinder 211 is activated, pushing the connecting plate 212 to move axially, which in turn drives the rotating shaft 217 and the sliding frame 2181 to slide along the slide groove 221 on the machining table 11. By extending and retracting the cylinder 211, the position of the workpiece in the axial direction can be adjusted to achieve axial feed and meet the cutting requirements of different positions. During the cutting process, metal chips will fall onto the surface of the machining table 11. Since the top of the machining table 11 is equipped with multiple triangular guide blocks 222, the chips can be effectively guided into the slide groove 221. At this time, the vacuum cleaner 224 installed at the bottom of the mounting frame 12 starts to work, and sucks the chips in the slide groove 221 into the dust collection bucket through the vacuum pipe 223 connected to it, thus completing the timely collection and cleaning of waste materials and keeping the machining area clean.
