Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to motor assembly equipment. Background Art

[0002] In today's society, electrical equipment is used more and more widely. The application of motors is not only reflected in industrial production and manufacturing, but also in people's daily life. The motor includes a motor casing, a rotor and a stator inside the casing, and end covers at both ends of the casing. When assembling the motor, the end covers need to be assembled with the casing.

[0003] Assembly equipment is required for motor assembly. Since motor products on different platforms have different diameters, different assembly tools are required when the diameter changes due to the different motor diameters. Therefore, tools of different sizes need to be made and managed, which creates requirements for assembly jigs. In the past, positioning jigs were customized for products of different diameters to meet the requirements, which would increase costs and complicate jig management. Utility Model Content

[0004] The utility model aims to provide a motor assembly device to solve the problem in the background technology that motor products with different diameter specifications need to be individually customized with corresponding jigs, which increases costs and makes management of multiple jigs complicated.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a motor assembly device, including a mold frame body, the mold frame body includes a lower mold plate, an upper mold plate and two columns, the two columns are respectively fixedly installed on both sides of the upper surface of the lower mold plate, and linear sleeves are installed through both ends of the upper mold plate. The linear sleeves are slidably installed on the outer surfaces of the columns at the same side positions. A universal positioning lower mold group is fixedly installed at the middle position of the upper surface of the lower mold plate, and two fixed plates are fixedly installed on the upper surface of the lower mold plate. The two fixed plates are respectively located on both sides of the universal positioning lower mold group, and a motor is fixedly installed on the side of one of the fixed plates, and a bidirectional threaded rod is rotatably installed between the two fixed plates, and the output shaft of the motor is connected to the bidirectional threaded rod. One end of the threaded rod is fixedly connected, and threaded plates are threadedly installed on the outer surfaces of the two sections of the thread of the two-way threaded rod, and a number of push-pull rods are fixed on the opposite surfaces of the two threaded plates. The push-pull rods slide through and extend into the interior of the universal positioning lower module and are fixedly installed with a positioning disk. The inner wall of the universal positioning lower module is provided with a receiving groove for accommodating the positioning disk. A cylinder connecting head is fixedly installed at the middle position of the upper template, and a combined upper mold is installed at the bottom end of the cylinder connecting head. The combined upper mold is located directly above the universal positioning lower module, and a sliding seat is slidably provided on the outer surface of one of the columns, and a contact switch is fixedly installed on the upper surface of the sliding seat, and a resistance rod is fixedly installed on the lower surface of the upper template, and the resistance rod is located directly above the contact switch.

[0006] By adopting the above solution, the motor is electrically connected to the external power supply, and the contact switch is electrically connected to the external cylinder.

[0007] In the above scheme, it should be noted that by setting the lower template, the upper template, and the column, the universal positioning lower template and the assembly upper template are used together. The assembly upper template and the universal positioning lower template are arranged relative to each other up and down to ensure concentricity. The universal positioning lower template cooperates with the two-way threaded rod and the clamping plate to fix and clamp the shell, and is compatible with motor shell products of different diameters on different platforms, reducing the production and management of tooling and fixtures of various diameters, achieving rapid changeover, and reducing labor costs. The sliding seat is used in conjunction with the contact switch and the resistance rod. When the upper template moves downward for assembly, the resistance rod moves downward synchronously, and when the resistance rod touches the contact switch, the surface reaches the standard position for press-fitting, which can effectively avoid excessive or inadequate press-fitting, and the sliding seat can adjust its position by moving up and down through the fixed tooth plate and the movable tooth plate, and can be adaptively adjusted according to the different press-fitting requirements of different products.

[0008] As a preferred implementation, a column blocking piece is fitted on the top of the column, and a fixing screw is threadedly installed between the column blocking piece and the column.

[0009] By adopting the above scheme, the diameter of the column baffle is larger than the diameter of the column. The column baffle is fixed to the top of the column by a fixing screw, which can limit the upper template and prevent the upper template from separating from the column when moving upward. The column baffle can be removed by unscrewing the fixing screw, and then the upper template can be slid upward to remove it, which is convenient for disassembly and assembly.

[0010] As a preferred embodiment, a plurality of guide rods are fixedly mounted on the side of the lower template, and the threaded plate is slidably mounted on the outer surfaces of the plurality of guide rods at the same side.

[0011] By adopting the above scheme, when the bidirectional threaded rod rotates to drive the threaded plate to move, the threaded plate will slide on the surface of the guide rod. The setting of the guide rod can support and guide the movement process of the threaded plate to improve the smoothness of movement.

[0012] As a preferred embodiment, a second accommodating groove is opened on the lower surface of the inner wall of the universal positioning lower module, and a pushing plate is arranged inside the second accommodating groove, and a pushing rod is fixedly installed on the lower surface of the pushing plate. The pushing rod slides through the universal positioning lower module and the lower template and is fixedly installed with a handle.

[0013] By adopting the above scheme, the push plate is used in conjunction with the push rod. After the assembly operation, the push rod can be driven by the handle to drive the push plate to move upward, and then the assembled motor can be pushed upward and the universal positioning lower module can be pushed out, which is convenient for material removal operation.

[0014] As a preferred embodiment, a notch is provided on the surface of the column where the sliding seat is located, and a fixed tooth plate is fixedly installed on the inner wall of the notch. A movable tooth plate is movably provided under the sliding seat, and the movable tooth plate and the fixed tooth plate are engaged with each other for use.

[0015] By adopting the above solution, the sliding seat is locked when the fixed tooth plate and the movable tooth plate are engaged, and the sliding seat cannot slide on the surface of the column. When the movable tooth plate and the fixed tooth plate are disengaged, the sliding seat is unlocked, and the sliding seat can slide up and down on the surface of the column.

[0016] As a preferred embodiment, an extension block is fixedly installed on the lower surface of the sliding seat, a sliding rod is slidably installed on the extension block, an operating plate is fixedly installed on one end of the sliding rod, the other end of the sliding rod is fixedly connected to a movable tooth plate, and a spring is fixedly installed between the extension block and the movable tooth plate.

[0017] With the above solution, the sliding rod is used in conjunction with the spring. When the sliding rod pulls the movable tooth plate to disengage from the fixed tooth plate, the spring is in a deformed state. Therefore, the elastic force of the spring can be used to drive the movable tooth plate to quickly reset and mesh with the fixed tooth plate.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The motor assembly equipment is used by setting a lower template, an upper template, and a column to cooperate with a universal positioning lower mold and an assembly upper mold. The assembly upper mold and the universal positioning lower mold are arranged relative to each other to ensure concentricity. The universal positioning lower mold cooperates with a bidirectional threaded rod and a clamping plate to fix and clamp the shell. It is compatible with motor shell products of different diameters on different platforms, reduces the production and management of tooling and fixtures of various diameters, realizes rapid changeover, and reduces labor costs.

[0020] The motor assembly equipment is used in conjunction with a contact switch and a resistance rod by setting a sliding seat. When the upper template moves downward for assembly, the resistance rod moves downward synchronously, and when the resistance rod touches the contact switch, the surface reaches the standard press-fitting position, which can effectively avoid excessive press-fitting or inadequate press-fitting. The sliding seat can adjust its position by moving up and down through a fixed tooth plate and a movable tooth plate, and can be adaptively adjusted according to the different press-fitting requirements of different products.

At this time, the contact switch 15 will control the external cylinder to stop working or move upward, which can prevent excessive or inadequate press-fitting. When the upper template 2 is reset, the handle is operated upward, and the handle will drive the push rod 20 to drive the push plate 21 to move upward, and then the assembled product will be pushed out of the universal positioning lower mold 5.
