Description

Technical Field

[0001] The utility model relates to the technical field of axially movable motors, and specifically relates to an axially movable motor. Background Technique

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. It is divided into a motor and a generator. In the modern metal processing process, a motor is required to rotate and move the tool axially horizontally during cutting and grinding. Therefore, axially movable motors are very frequently used in mechanized production. With the progress of technology, the types of axially movable motors are also increasing.

[0003] In response to this, Chinese Patent No. CN201199658Y proposes an axially movable motor, which overcomes the defects in the prior art such as being restricted by the dovetail groove of the carriage, the upper and lower seats of the carriage, and the matching accuracy of the screw and nut, having a complex structure, a large volume, many assembly processes, a large driving force, and a high production cost. It is suitable for supporting various equipment with a connecting tailstock and turning, milling, and planing machine tools.

[0004] However, when the above technical solution is implemented, the motor body is connected and installed to the bottom carriage. When axially moving, a mechanism is required to move the motor body on the carriage to realize the axial movement of the motor output end. During the movement, the floor area between the motor and the bottom carriage continuously expands. Although the floor area is reduced when not working, a certain moving area still needs to be reserved during work, which is not conducive to installation on workstations with small dimensions. In response to this, this design proposal presents an axially movable motor. Content of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide an axially movable motor to solve the problem that the axially movable motor needs a connecting structure and the motor to move relative to each other during axial movement, increasing the floor area.

[0006] To achieve the above purpose, the utility model proposes an axially movable motor, which includes a machine shell, a reduction motor, and an axial movement mechanism installed outside the machine shell.

[0007] The axial movement mechanism includes a protective cover installed at one end of the casing. A sleeve shaft is rotatably provided on one side of the protective cover. A first limit card slot is provided at one end of the sleeve shaft. A moving shaft is inserted through the inner wall of the first limit card slot. A groove is provided on the outer wall of the moving shaft. A first limit card block is fixedly provided at one end of the moving shaft, and the outer wall of the first limit card block is inserted and connected with the inner wall of the first limit card slot. A limit piece is sleeved on the outer wall of the moving shaft, and the outer wall of the limit piece is rotatably connected with the inner wall of the groove. A sleeve is fixedly provided at the edge of one side of the protective cover, and an electric telescopic rod is fixedly provided on the inner wall of the sleeve.

[0008] In one example, the output end of the electric telescopic rod is fixedly connected with one side of the limit piece, and an installation screw rod is fixedly provided at the other end of the moving shaft.

[0009] In one example, the reduction motor is installed on the inner wall of the casing.

[0010] In one example, a docking groove is provided at the edge of one end of the casing. A clamping ring is fixedly provided at the edge of the other side of the protective cover, and the outer wall of the clamping ring is inserted and connected with the inner wall of the docking groove.

[0011] In one example, a rubber gasket is fixedly provided on one side of the inner wall of the clamping ring, and the inner wall of the rubber gasket is in contact with one side of the inner wall of the docking groove.

[0012] In one example, a second limit card slot is provided at the other end of the sleeve shaft, and a second limit card block is fixedly provided at the output end of the reduction motor.

[0013] In one example, the outer wall of the second limit card block is inserted and connected with the inner wall of the second limit card slot. Installation plates are fixedly provided on both sides of the bottom of the casing.

[0014] In one example, a switch panel is fixedly provided on one side of the outer wall of the casing. The electric telescopic rod and the reduction motor are both electrically connected to an external power supply through the switch panel.

[0015] The axial moving motor proposed by the present utility model can bring the following beneficial effects:

[0016] For this axial moving motor, by setting the axial movement mechanism, while the reduction motor drives the sleeve shaft and the moving shaft to rotate, the electric telescopic rod is started to push the limit piece to move together, and drives the moving shaft to move in the axial direction. And the limit piece is rotatably connected with the groove on the moving shaft, which limits it while not affecting the rotation of the moving shaft, realizing the axial movement of the output end of the motor. There is no need to move the motor and the machine base, reducing the installation area of the motor equipment, which is beneficial to the installation of the equipment on machines with more sizes.

Specific embodiments

[0024] In order to more clearly illustrate the overall concept of the present utility model, the following is a detailed description by way of example in conjunction with the drawings in the specification.

[0025] The embodiments are as follows:

[0026] The present utility model provides an axially movable motor as Figures 1-5 shown, including a machine shell 1, a reduction motor 3, and an axial movement mechanism 2 installed outside the machine shell 1;

[0027] The axial movement mechanism 2 includes a protective cover 201 installed at one end of the housing 1. A sleeve shaft 202 is rotatably provided on one side of the protective cover 201. A first limit card slot 203 is opened at one end of the sleeve shaft 202. A moving shaft 204 is inserted through the inner wall of the first limit card slot 203. A groove 205 is opened on the outer wall of the moving shaft 204. A first limit card block 206 is fixedly provided at one end of the moving shaft 204, and the outer wall of the first limit card block 206 is inserted and connected with the inner wall of the first limit card slot 203. A limit piece 207 is sleeved on the outer wall of the moving shaft 204, and the outer wall of the limit piece 207 is rotatably connected with the inner wall of the groove 205. A sleeve 208 is fixedly provided at the edge of one side of the protective cover 201. An electric telescopic rod 209 is fixedly provided inside the sleeve 208. When the first limit card block 206 is inserted into the first limit card slot 203 at one end of the sleeve shaft 202, the outer wall of the first limit card block 206 is completely in contact with the inner wall of the first limit card slot 203. When the sleeve shaft 202 is driven by the reduction motor 3, it will drive the first limit card block 206 to rotate synchronously, and then drive the moving shaft 204 at one end to rotate synchronously. And the outer wall of the limit piece 207 is rotatably connected with the inner wall of the groove 205. At the same time, the moving shaft 204 is limited by the inner wall of the groove 205. When the moving shaft 204 rotates through the limit piece 207, the limit piece 207 can also drive the moving shaft 204 to move when moving back and forth. When the moving shaft 204 moves, the first limit card block 206 slides in the first limit card slot 203.

[0028] The output end of the electric telescopic rod 209 is fixedly connected with one side of the limit piece 207. An installation screw rod 210 is fixedly provided at the other end of the moving shaft 204. The installation screw rod 210 is mainly used for installing the tool and the grinding piece;

[0029] Further, the reduction motor 3 is installed on the inner wall of the housing 1.

[0030] A docking groove 4 is opened at the edge of one end of the housing 1. A clamping ring 5 is fixedly provided at the edge of the other side of the protective cover 201, and the outer wall of the clamping ring 5 is inserted and connected with the inner wall of the docking groove 4. The clamping ring 5 is located on the other side of the protective cover 201 and protrudes at its edge.

[0031] A rubber gasket 6 is fixedly provided on one side of the inner wall of the clamping ring 5, and the inner wall of the rubber gasket 6 is in contact with one side of the inner wall of the docking groove 4. When the clamping ring 5 is completely inserted into the docking groove 4, the rubber gasket 6 is completely clamped into the docking groove 4 and is extruded with the inner wall of the docking groove 4, so that the clamping ring 5 is not easily separated during the operation of the motor;

[0032] Further, a second limit card slot 7 is provided at the other end of the sleeve shaft 202, and a second limit card block 8 is fixedly provided at the output end of the reduction motor 3. When installing the protective cover 201, it is necessary to rotate the angle to lock the second limit card slot 7 at the other end of the sleeve shaft 202 with the second limit card block 8 at the output end of the reduction motor 3, so that the sleeve shaft 202 can be rotated when the motor is driven.

[0033] The outer wall of the second limit card block 8 is inserted and connected with the inner wall of the second limit card slot 7. Installation plates 9 are fixedly provided on both sides of the bottom of the machine shell 1, and screw holes are provided in the installation plates 9 to facilitate the installation of the machine shell 1 on the machine equipment through the screw holes.

[0034] Working principle: When using the axially movable motor in this design solution, first install the reduction motor 3 through the machine shell 1, and install it on the machine equipment through the screw holes provided in the installation plates 9 at the bottom of the machine shell 1. When the motor is in use, install the tool through the installation screw 210. Then, when cutting and grinding the workpiece, the protective cover 201 is snapped into the docking groove 4 at one end of the machine shell 1 through the snap ring 5, so that the rubber gasket 6 is squeezed against it and fixed in the docking groove 4. At this time, the second limit card block 8 at the output end of the reduction motor 3 is snapped into the second limit card slot 7 at one end of the sleeve shaft 202. Drive the machine shell 1 of the motor to rotate the sleeve shaft 202, so that the moving shaft 204 rotates accordingly. The moving shaft 204 is stuck in the first limit card slot 203 at the other end of the sleeve shaft 202 through the first limit card block 206 and rotates together with the rotation of the sleeve shaft 202. Then, start the electric telescopic rod 209 in the sleeve 208 to push the limit piece 207 to move, so that it drives the moving shaft 204 to move axially, realizing the axial movement of the tool. During the whole process, the reduction motor 3 and the machine shell 1 are fixed in place without moving, only the axial movement of the output end is carried out, and there is no need to reserve the space position for the motor to move, reducing the floor area and being beneficial to the installation of the motor equipment.
