Description

Technical Field

[0001] The utility model relates to the technical field of motor casings, in particular to a quick-disassembly mechanism for a motor casing. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magneto-electrical rotation torque. Motors are divided into DC motors and AC motors according to the power supply used. Most motors in the power system are AC motors, which can be synchronous motors or asynchronous motors. The motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines.

[0003] The housing and back cover of an existing motor are usually connected by bolts, and the number of bolts is multiple. Therefore, when the internal components of the motor are damaged and need to be repaired or replaced, the back cover and the housing need to be separated. Since the bolts need to be removed one by one, the separation of the back cover and the housing of the motor is not fast enough. At the same time, the bolts are prone to rust in a humid environment, which will have a certain impact on the maintenance of the motor. Utility Model Content

[0004] The utility model aims to solve the shortcoming in the prior art that the rear cover and the housing of the motor cannot be separated quickly enough, and provides a motor housing quick-disassembly mechanism.

[0006] As a preferred implementation, the outer surface of the extruded sheet is fixedly connected to a limiting block, the number of the limiting blocks is two, and a limiting groove matching the limiting block is formed inside the connecting block.

[0007] As a preferred implementation, one end of the pull rod is fixedly connected to a pull block, and the shell is provided with a positioning groove, and the number of the positioning grooves is two.

[0008] As a preferred embodiment, a mounting mechanism is provided on one side of the fixing mechanism, and the mounting mechanism comprises a rear cover, and a connecting ring is fixedly connected to one end of the rear cover close to the shell.

[0010] As a preferred implementation, positioning posts are fixedly connected to the outer surface of the connecting ring, and the number of the positioning posts is two.

[0011] As a preferred embodiment, the back cover is provided with two screw grooves.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] The utility model provides a fixing mechanism so that the housing and the back cover of the motor can be quickly separated and installed, so that the rotor and other components in the housing can be repaired or replaced, thereby improving the convenience of maintenance of the motor.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a motor housing quick-release mechanism, comprising: a fixing mechanism 1, the fixing mechanism 1 comprises a shell 11, a fixing groove 12 is provided on the shell 11, a connecting block 13 is fixedly connected to the top of the shell 11, a clamping block 14 is penetrated inside the connecting block 13, the clamping block 14 is slidably connected to the connecting block 13, an extrusion sheet 15 is fixedly connected to one end of the clamping block 14, a pull rod 16 is fixedly connected to the side of the extrusion sheet 15 away from the clamping block 14, and the pull rod 16 penetrates the connecting block 13. Internally, the pull rod 16 is slidably connected to the connecting block 13, and a spring 17 is sleeved on the outer surface of the pull rod 16. The two ends of the spring 17 are respectively fixedly connected to the outer surface of the extrusion sheet 15 and the inner wall of the connecting block 13. The outer surface of the extrusion sheet 15 is fixedly connected to a limiting block 18, and the number of the limiting blocks 18 is two. A limiting groove that matches the limiting block 18 is opened inside the connecting block 13, and one end of the pull rod 16 is fixedly connected to a pull block 19. A positioning groove 101 is opened on the shell 11, and the number of the positioning grooves 101 is two.

[0027] In this embodiment, by providing a fixing mechanism 1, the shell 11 and the back cover 21 can be easily disassembled and installed, and a spring 17 is provided. By utilizing the characteristic that the spring 17 can generate elastic force when compressed by the extrusion sheet 15, the card block 14 can be automatically reset when the shell 11 is connected to the back cover 21, so that the card block 14 can automatically and tightly engage with the card slot 24 provided on the plug block 23 to maintain the stability of the connection between the shell 11 and the back cover 21. In addition, two limit blocks 18 are provided, and a limit slot that matches the limit block 18 is provided inside the connecting block 13. Therefore, the special-shaped card block 14 will not rotate slightly when reset due to the twisting effect of the spring 17, thereby ensuring the accuracy of the engagement connection between the card block 14 and the plug block 23.

[0028] Example 2

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, a mounting mechanism 2 is provided on one side of the fixing mechanism 1, and the mounting mechanism 2 includes a back cover 21, and a connecting ring 22 is fixedly connected to one end of the back cover 21 close to the shell 11, and an insert block 23 is fixedly connected to the outer surface of the connecting ring 22, and a card slot 24 that fits with the card block 14 is provided on the insert block 23, and a positioning column 25 is fixedly connected to the outer surface of the connecting ring 22, and the number of the positioning columns 25 is two, and a screwing groove 26 is provided on the back cover 21, and the number of the screwing groove 26 is two.

[0030] In this embodiment, by providing the installation mechanism 2, it can be easier to connect the back cover 21 to the shell 11, and the two positioning posts 25 can be used in conjunction with the two positioning grooves 101, so that the plug block 23 can be positioned and installed. When the positioning post 25 is placed at the counterclockwise end of the positioning groove 101, the plug block 23 is just placed at the counterclockwise end of the fixing groove 12, and the back cover 21 can be conveniently rotated through the two screw grooves 26 until the plug block 23 is engaged and connected with the card block 14.

[0031] Working principle:

[0032] like Figure 1-Figure 5 As shown, when the utility model is in use, if it is necessary to separate the rear cover 21 from the housing 11, the pull block 19 can be pulled to indirectly drive the card block 14 to disengage from the card slot 24 provided on the plug block 23, so that the rear cover 21 can be separated from the housing 11. If it is necessary to install the rear cover 21, the plug block 23 can be positioned and installed by the positioning column 25. The maintenance personnel can turn their eyes sideways so that the positioning column 25 is installed at the counterclockwise end of the positioning groove 101. When the positioning column 25 completely enters the positioning groove 101, the plug block 23 will enter the counterclockwise end of the fixing groove 12. At this time, the back cover 21 is rotated clockwise by screwing the groove 26, and then the plug block 23 will also rotate clockwise, and squeeze the card block 14 into the connecting block 13 while rotating. At this time, the extrusion sheet 15 will compress the spring 17 and make the spring 17 generate elastic force. When the plug block 23 contacts the clockwise end of the fixing groove 12, the elastic force of the spring 17 will be released instantly and the card block 14 will be automatically reset. At this time, the card block 14 will automatically fit tightly with the card groove 24 opened on the plug block 23 under the guidance of the two limit blocks 18, so as to complete the convenient connection between the back cover 21 and the shell 11.
