Technical Field

[0001] This utility model relates to the field of motor assembly technology, and in particular to a motor worm gear mounting device. Background Technology

[0002] A worm gear is a gear with one or more helical teeth that meshes with a worm wheel to form an interlocking gear pair. The worm gear can be mounted on the output shaft of a motor, and the motor drives the worm gear to rotate.

[0003] Existing worm gear mounting devices mainly rely on a cylinder to drive a push rod to press the worm gear onto the motor output shaft. The accuracy of this method depends primarily on the precision of the cylinder itself, which may result in significant differences in the assembly dimensions between the worm gear and the motor shaft. Utility Model Content

[0004] The technical solution to be solved by this utility model is to provide a motor worm gear mounting device with high installation accuracy.

[0005] The technical solution adopted by this utility model is: a motor worm gear mounting device, which includes a controller, a base plate, a motor fixing mechanism mounted on the base plate for fixing the motor, a pressing mechanism mounted on the base plate for pressing the worm gear into the motor, and a cover for covering the fixing mechanism and the pressing mechanism. The pressing mechanism includes a fixing plate fixed to the floor, an electric cylinder fixed to the fixing plate, a connecting plate mounted on the output shaft of the electric cylinder, a pressure plate fixed to the connecting plate, a pressure sensor connected to the pressure plate at one end, a push plate connected to the other end of the pressure sensor, a guide post mounted between the pressure plate and the push plate, and a sleeve. A spring is mounted on the guide post, with one end abutting against the pressure plate and the other end against the push plate. A push shaft is also mounted on the push plate to press the worm gear into the motor. A first laser displacement sensor is mounted on the connecting plate to position the connecting plate. A first light-blocking plate matching the first laser displacement sensor is mounted on the base plate. A second laser displacement sensor for positioning the push plate is mounted on the motor fixing mechanism. A second light-blocking plate matching the second laser displacement sensor is mounted on the push plate. The electric cylinder, pressure sensor, first laser displacement sensor, and second laser displacement sensor are all electrically connected to the controller.

[0006] Preferably, the motor fixing mechanism includes a fixing seat with a groove for inserting the motor, a stop for abutting the rear end of the motor, and a straightening plate for adjusting the position of the stop, with the second laser displacement sensor fixed on one side of the fixing seat.

[0007] Preferably, the cover has an opening at the front and gratings on both sides of the opening, and the gratings are electrically connected to the controller.

[0008] Preferably, the cover is provided with detachable transparent panels on the front, back, and top sides for easy observation by the user.

[0009] Preferably, handles are provided on the bottom plates on both sides of the cover.

[0010] Preferably, shock-absorbing pads are provided at the four corners of the bottom of the base plate.

[0011] Compared with the prior art, the present invention has the following advantages: by using the first laser displacement sensor and the second laser displacement sensor to detect the position of the connecting plate and the push plate, and by combining the pressure sensor to detect the pressure of the extruding worm, it is possible to better determine whether the worm is installed in place, resulting in higher overall installation accuracy.

[0012] This fixing mechanism allows for easy fixation of the motor, and the position of the stop can be adjusted according to the size of the motor, resulting in high overall adaptability.

[0013] A cover is installed, and a light grating is placed at the opening of the cover. This can effectively prevent users from putting their hands into the device when it is working, reducing safety hazards.

[0014] The transparent panel allows users to view the device's operation from different directions and also facilitates maintenance.

[0015] Handles are provided on both sides of the base plate, which makes it easy for users to lift the entire device and move it.

[0016] Shock-absorbing pads are installed at the four corners of the base plate, so that the overall vibration of the device is smaller when it is working, thereby making the installation accuracy of the worm gear higher. Attached Figure Description

[0023] The base plate 1 has shock-absorbing pads 22 at its four bottom corners, and handles 21 are provided on the floor on both sides of the cover 2.

[0024] Cover 2 is fixed on base plate 1 and is used to cover the fixing mechanism and pressing mechanism. Cover 2 has an opening at the front and transparent plates 20 on both sides and top of cover 2 for easy observation by the user.

[0025] The fixing mechanism includes a fixing base 16, a stop block 17, and a straightening plate 18, wherein:

[0026] The mounting base 16 is fixed on the base. The mounting base 16 is provided with a groove for embedding the motor and a mounting slot for the mounting part on the stop block 17 to extend into.

[0027] The mounting part of the stop block 17 extends into the mounting groove, and the position of the mounting part of the stop block 17 in the mounting groove can be adjusted according to the size of the motor. Then, it is locked onto the fixed seat 16 by the locking member. When the motor is installed on the fixed seat 16, one end of the stop block 17 will abut against the rear end of the motor.

[0028] The straightening plate 18 is used to abut against the other end of the stop block 17 and is fixed to the fixing seat 16 by a locking member;

[0029] The pressing mechanism includes a fixed plate 3, an electric cylinder 4, a connecting plate 5, a pressure plate 6, a pressure sensor 7, a push plate 8, a guide column 9, a spring 10, a push shaft 11, a first laser displacement sensor 12, a first light-blocking plate 13, a second laser displacement sensor 14, and a second light-blocking plate 15, wherein:

[0030] The fixing plate 3 is fixed on the base and has a through hole in the middle for the power supply cylinder 4 to extend into and install.

[0031] The electric cylinder 4 is mounted on the fixed plate 3, which has an output shaft. Since the electric cylinder 4 is a conventional product of the prior art, it will not be described in detail here.

[0032] The connecting plate 5 is connected to the output shaft of the electric cylinder 4 via a floating connector, and the two sides of the connecting plate 5 are also slidably connected to the fixed plate 3 via guide rods;

[0033] Pressure plate 6 is fixed on connecting plate 5;

[0034] Pressure sensor 7, model LSZ-F03A, is mounted on pressure plate 6 on one side and push plate 8 on the other side, and can detect the pressure between the two.

[0035] A guide post 9 is provided between the push plate 8 and the pressure plate 6, that is, the push plate 8 and the pressure plate 6 can move relative to each other. One end of the guide post 9 is fixed on the pressure plate 6, and the other end can slide along the through hole on the push plate 8. A spring 10 is also sleeved on the guide post 9. One end of the spring 10 abuts against the pressure plate 6, and the other end of the spring 10 abuts against the push plate 8.

[0036] Push shaft 11, fixed on push plate 8, is used to press the worm gear and then press the worm gear into the output shaft of the motor;

[0037] The first laser displacement sensor 12, model HG-C1050, is fixed on one side of the connecting plate 5. The first light-blocking plate 13 is fixed on the base. When the connecting plate 5 moves forward with the output shaft of the electric cylinder 4, it will match the first light-blocking plate 13, and the position of the connecting plate 5 can be located at this time.

[0038] The second laser displacement sensor 14, model HG-C1050, is fixed on one side of the fixed base 16. The second light-blocking plate 15 is fixed on the push plate 8. In this way, when the push plate 8 moves forward with the output shaft of the electric cylinder 4, it will match the second laser displacement sensor 14, and the position of the push plate 8 can be located.

[0039] The controller, used to control the electric cylinder 4, pressure sensor 7, first laser displacement sensor 12 and second laser displacement sensor 14, is a conventional controller in the prior art, so it is not described in detail in this application;

[0040] The working principle of this embodiment is as follows: When the electric cylinder 4 is working, it will drive the output shaft to move, which in turn will drive the connecting plate 5 and the pressure plate 6 to move, and then drive the push plate 8 and the push shaft 11 to move, thereby pressing the worm into place through the push shaft 11. The first laser displacement sensor 12 can detect the position of the connecting plate 5 and the pressure plate 6, the second laser displacement sensor 14 can detect the position of the push plate 8 and the push shaft 11, and the pressure sensor 7 can detect the pressure between the pressure plate 6 and the push plate 8. Based on these three sensors, it is possible to determine whether the worm has been pressed into place.

[0041] Example 2:

[0042] The difference from Embodiment 1 is that in Embodiment 2, gratings 19 are provided on both sides of the opening at the front of the cover 2. The gratings 19 are model NA-N12. In this way, the gratings 19 can be used to identify whether an object has been inserted into the cover 2. That is, when the device is running, the gratings 19 are turned on to prevent the user's hand from being inserted into the cover 2, which greatly reduces the safety hazard.
