Description

Technical Field

[0001] This application relates to the technical field of motors, and specifically to a housing for a reduction motor. Background Art

[0002] A reduction motor refers to an integrated body of a reducer and a motor. Such an integrated body is usually also called a gear reduction motor or a gear reduction electric motor, and is usually supplied as a complete set after being integrally assembled by a professional reducer manufacturer. Reduction motors are widely used in the steel industry, machinery industry, etc. The advantages of the popular micro reduction motors in the 21st century are simplified design and space saving, while the power, reduction ratio, and torque do not decrease. A reduction motor generally achieves the effect of increasing torque and reducing speed by combining gears of different sizes inside the reduction motor with a power device such as an electric motor, an internal combustion engine, or other high-speed rotating devices.

[0003] The existing patent (publication number: CN208369395U) discloses a micro spiral bevel reduction motor, including a housing, a top shell, and an electric motor. The top shell is located at the top of the housing, the electric motor is located inside the housing, a speed limiting runner is snap-connected inside the top shell, a first transmission wheel and a second transmission wheel are arranged inside the speed limiting runner, and the second transmission wheel is snap-connected to the first transmission wheel. The first transmission wheel is snap-connected to the rotating shaft of the electric motor. A third transmission wheel is snap-connected to the top of the speed limiting runner, a transmission shaft is embedded at the top of the third transmission wheel, and a transmission spiral bevel is snap-connected to the top of the transmission shaft.

[0004] The above-mentioned comparative document points out that by setting the speed limiting runner, the first transmission wheel, and the second transmission wheel, it is convenient to reduce the speed through the mutual transmission of gears to meet the need for speed reduction. By setting the fixing seat and the snap plate, it is convenient to disassemble and replace the reduction motor by snap-connecting the housing buckle with the fixing seat without the need to fix it with bolts again. However, when the housing buckle is snap-connected with the fixing seat in this device, there is no limiting device after installation, which is likely to cause looseness during use. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, this application provides a housing for a reduction motor, which has the advantages of being convenient for installing the reduction motor, etc., and solves the problems that by setting the speed limiting runner, the first transmission wheel, and the second transmission wheel, it is convenient to reduce the speed through the mutual transmission of gears to meet the need for speed reduction. By setting the fixing seat and the snap plate, it is convenient to disassemble and replace the reduction motor by snap-connecting the housing buckle with the fixing seat without the need to fix it with bolts again. However, when the housing buckle is snap-connected with the fixing seat in this device, there is no limiting device after installation, which is likely to cause looseness during use.

[0006] To achieve the above object, the present application provides the following technical solution: A deceleration motor housing, including a fixed seat, a deceleration motor and a limit plate. Both sides inside the fixed seat are provided with dovetail grooves. Two first through holes are provided on both sides of the fixed seat. A chute is provided on one side of each of the two dovetail grooves. A slide bar is slidably connected inside each of the four first through holes in pairs. One side of each pair of the four slide bars is fixedly connected to a slide plate. One end of each of the two slide plates away from the slide bar is fixedly connected to a first plug board.

[0007] Two dovetail tenons distributed in a mirror image are fixedly connected to the outer wall of the deceleration motor. A first slot is provided on one side of each of the two dovetail tenons. Two second slots distributed in a mirror image are provided at the upper end of the limit plate. Two second through holes are provided on both sides of the limit plate.

[0008] Through the above solution, through the cooperation of the dovetail groove and the dovetail tenon, and the linkage design of components such as the slide bar, the slide plate and the first plug board, a stable connection between the deceleration motor and the fixed seat is achieved. By sliding the slide bar in the through hole and moving the slide plate in the chute, the position of the first plug board can be conveniently adjusted to accurately insert it into the first slot of the deceleration motor. This design ensures a tight fit between the deceleration motor and the fixed seat, improves the stability of the fixation, and since the sliding and plugging methods are adopted, the deceleration motor housing can be conveniently disassembled when maintenance or replacement is required.

[0009] Further, two springs are fixedly connected to the bottom ends of the two first plug boards. A pull ring is fixedly connected to one end of each pair of the four slide bars away from the slide plate. One end of each pair of the four springs away from the slide plate is fixedly connected to the fixed seat.

[0010] Through the above solution, the design of the pull ring enables the user to more conveniently pull the slide bar, thereby controlling the movement of the slide plate and the first plug board. The tension of the spring can, to a certain extent, maintain the tight contact between the first plug board and the slot, thereby enhancing the connection stability between the deceleration motor and the fixed seat.

[0011] Further, two second plug boards distributed in a mirror image are fixedly connected to the bottom end of the fixed seat. Two positioning holes are provided inside each of the two second plug boards.

[0012] Through the above solution, the design of the second plug board increases the contact area between the fixed seat and other components or the mounting surface, thereby improving the overall stability. The existence of the positioning holes enables the second plug board to be accurately positioned with other components.

[0013] Further, bolts are slidably connected inside the four second through holes. One end of the four bolts, which are grouped in pairs, away from the second through holes is fixedly connected to a first mounting bracket and a second mounting bracket respectively. Two lock tongues distributed in a mirror image are fixedly connected to one side of the first mounting bracket, and two lock catches distributed in a mirror image are fixedly connected to one side of the second mounting bracket.

[0014] Through the above solution, by the sliding of the bolts in the second through holes and in cooperation with the first mounting bracket and the second mounting bracket, a mechanical locking mechanism can be realized.

[0015] Further, both of the dovetail tenons are slidably arranged inside the dovetail grooves, and both of the first insertion plates are slidably arranged inside the first insertion slots.

[0016] Through the above solution, the sliding fit design of the dovetail grooves and the dovetail tenons ensures the positioning accuracy of the reduction motor on the fixed seat. This helps to reduce the performance degradation or damage risk caused by assembly errors. The sliding assembly method makes the assembly and disassembly of components easier. Users can install or disassemble the components in place with a simple sliding action without using complex tools or performing cumbersome operations.

[0017] Further, both of the second insertion plates are slidably arranged inside the second insertion slots.

[0018] Through the above solution, the second insertion plates can be slidably arranged inside the second insertion slots, making the installation and disassembly process of the fixed seat and other components simpler and faster. Users only need to align the second insertion plates and slide them into the second insertion slots to complete the installation without using complex tools or performing cumbersome fixing operations.

[0019] Further, all four bolts are slidably arranged inside the positioning holes.

[0020] Through the above solution, the bolts are slidably arranged inside the positioning holes, which can ensure the precise fit between the bolts and the positioning holes. This design enables the bolts to be stably fixed in the positioning holes, avoiding structural instability caused by position deviation or loosening.

[0021] Further, both of the lock tongues are slidably arranged inside the lock catches.

[0022] Through the above solution, the design of the lock tongues being slidably arranged inside the lock catches allows for quick and simple locking and unlocking operations. Users only need to slide the lock tongues to achieve the cooperation or separation with the lock catches, thereby quickly fixing or releasing the relevant components.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] The deceleration motor housing realizes a stable connection between the deceleration motor and the fixed seat through the cooperation of dovetail grooves and dovetail tenons, as well as the linkage design of components such as sliding rods, sliding plates, and first plug plates. By sliding the sliding rod in the through hole and moving the sliding plate in the sliding groove, the position of the first plug plate can be conveniently adjusted to accurately insert it into the first slot of the deceleration motor. This design ensures a tight fit between the deceleration motor and the fixed seat, improving the stability of fixation. Since the sliding and plugging methods are adopted, the deceleration motor housing can be easily disassembled when maintenance or replacement is required. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3, A speed reduction motor housing in this embodiment includes a fixed seat 1, a speed reduction motor 10, and a limiting plate 13.

One end of the two sliding plates 6 away from the sliding rods 5 is fixedly connected with a first insertion plate 7. By sliding the sliding rods 5 in the through holes and moving the sliding plates 6 in the sliding grooves 4, the position of the first insertion plate 7 can be conveniently adjusted.

[0034] Please refer to Figure 1 , Figure 2 and Figure 5 , Two dovetail tenons 11 distributed in a mirror image are fixedly connected to the outer wall of the speed reduction motor 10. A first insertion slot 12 is provided on one side of each of the two dovetail tenons 11. Two second insertion slots 14 distributed in a mirror image are provided at the upper end of the limiting plate 13. Two second through holes 15 are provided on both sides of the limiting plate 13. Through the cooperation of the dovetail groove 2 and the dovetail tenon 11, as well as the linkage design of components such as the sliding rods 5, the sliding plates 6, and the first insertion plate 7, a stable connection between the speed reduction motor 10 and the fixed seat 1 is achieved.

[0035] Please refer to Figure 2 , Figure 3 and Figure 5 , Two springs 8 are fixedly connected to the bottom ends of the two first insertion plates 7. One end of each group of two of the four sliding rods 5 away from the sliding plates 6 is fixedly connected with a pull ring 9. One end of each group of two of the four springs 8 away from the sliding plates 6 is fixedly connected with the fixed seat 1. The design of the pull ring 9 enables the user to more conveniently pull the sliding rods 5, thereby controlling the movement of the sliding plates 6 and the first insertion plates 7. The tension of the springs 8 can, to a certain extent, maintain the close contact between the first insertion plates 7 and the insertion slots, thereby enhancing the connection stability between the speed reduction motor 10 and the fixed seat 1. Two second insertion plates 16 distributed in a mirror image are fixedly connected to the bottom end of the fixed seat 1. Two positioning holes 17 are provided inside each of the two second insertion plates 16. The design of the second insertion plates 16 increases the contact area between the fixed seat 1 and other components or the mounting surface, thereby improving the overall stability. The existence of the positioning holes 17 enables the second insertion plates 16 to be accurately positioned with other components. Four pins 18 are internally slidably connected in the four second through holes 15. One end of each group of two of the four pins 18 away from the second through holes 15 is respectively fixedly connected with a first mounting bracket 19 and a second mounting bracket 21. Two locking tongues 20 distributed in a mirror image are fixedly connected to one side of the first mounting bracket 19. Two locking buckles 22 distributed in a mirror image are fixedly connected to one side of the second mounting bracket 21. By sliding the pins 18 in the second through holes 15 and cooperating with the first mounting bracket 19 and the second mounting bracket 21, a mechanical locking mechanism can be achieved.

[0036] Please refer to Figure 4 andFigure 5 , both dovetail tenons 11 are slidably arranged inside the dovetail groove 2, and both first insertion plates 7 are slidably arranged inside the first insertion slots 12. The sliding fit design of the dovetail groove 2 and the dovetail tenons 11 ensures the positioning accuracy of the reduction motor 10 on the fixing base 1. This helps to reduce the performance degradation or damage risk caused by assembly errors. The sliding assembly method makes the assembly and disassembly of components easier. Users can install or disassemble the components in place through simple sliding actions without using complex tools or performing cumbersome operations. Both second insertion plates 16 are slidably arranged inside the second insertion slots 14. The ability of the second insertion plates 16 to be slidably arranged inside the second insertion slots 14 makes the installation and disassembly process of the fixing base 1 and other components simpler and faster. Users only need to align the second insertion plates 16 and slide them into the second insertion slots 14 to complete the installation without using complex tools or performing cumbersome fixing operations. All four pins 18 are slidably arranged inside the positioning holes 17. The pins 18 being slidably arranged inside the positioning holes 17 can ensure the precise fit between the pins 18 and the positioning holes 17. This design enables the pins 18 to be stably fixed in the positioning holes 17, avoiding structural instability caused by position deviation or loosening. Both locking tongues 20 are slidably arranged inside the lock catches 22. The design of the locking tongues 20 being slidably arranged inside the lock catches 22 allows for quick and simple locking and unlocking operations. Users only need to slide the locking tongues 20 to achieve the cooperation or separation with the lock catches 22, thereby quickly fixing or releasing the relevant components.

[0037] In this embodiment, for the housing of the reduction motor, through the cooperation of the dovetail groove 2 and the dovetail tenons 11, and the linkage design of components such as the slide bar 5, the slide plate 6, and the first insertion plate 7, a stable connection between the reduction motor 10 and the fixing base 1 is achieved. By the sliding of the slide bar 5 in the through hole and the movement of the slide plate 6 in the sliding groove 4, the position of the first insertion plate 7 can be conveniently adjusted to accurately insert it into the first insertion slot 12 of the reduction motor 10. This design ensures a tight fit between the reduction motor 10 and the fixing base 1, improving the stability of the fixation. Since the sliding and plugging methods are adopted, when the housing of the reduction motor 10 needs to be repaired or replaced, it can be conveniently disassembled.

[0038] It should be noted that the slide plate 6 is fixedly connected to the fixing base 1 through a spring 8, and the first insertion plate 7 is pushed into the first insertion slot 12 by the tension of the spring 8.

[0039] The working principle of the above embodiment is as follows:

[0040] Place the reduction motor 10 on the fixed seat 1, ensure that the two dovetail tenons 11 are aligned with the dovetail groove 2, and slide the dovetail tenons 11 to make them fully inserted into the dovetail groove 2 to achieve the preliminary positioning of the reduction motor 10 on the fixed seat 1. Pull the pull ring 9 to make the slide bar 5 slide outwards in the first through hole 3, driving the slide plate 6 to move in the chute 4. During the movement, the spring 8 is stretched to reserve potential energy for the subsequent insertion action. When the first insertion plate 7 moves to a position aligned with the first insertion slot 12 on the reduction motor 10, release the pull ring 9. The tension of the spring 8 causes the first insertion plate 7 to be quickly pushed into the first insertion slot 12 to achieve a stable connection between the reduction motor 10 and the fixed seat 1. Place the limit plate 13 above the reduction motor 10, ensure that the second insertion plate 16 is aligned with the second insertion slot 14, and slide the second insertion plate 16 to make it fully inserted into the second insertion slot 14 to achieve the preliminary installation of the limit plate 13. Slide the pin 18 into the positioning hole 17 through the second through hole 15 to ensure the precise fit between the pin 18 and the positioning hole 17. The other ends of the pin 18 are respectively connected to the first mounting bracket 19 and the second mounting bracket 21. At this time, the locking tongue 20 has been slidably arranged inside the lock catch 22 to complete the mechanical locking.
