Description

Technical Field

[0001] This utility model belongs to the field of motor assembly technology, specifically relating to a motor assembly structure for a vacuum cleaner. Background Technology

[0002] In the manufacturing of vacuum cleaner floor brushes, gears typically need to be press-fitted onto the motor's output shaft. Currently, manual assembly is commonly used: an operator places the gear sleeve onto the motor shaft and then applies axial impact or pressure based on experience to complete the press-fit.

[0003] However, this manual pressing process makes it difficult to precisely control the axial pressing depth of the gears. Due to differences in operating habits and work experience among different operators, the pressing depth of the gears cannot be consistently achieved, resulting in poor consistency in key dimensions of the assembled products, which directly affects the fitting accuracy and operational smoothness of the transmission components. Utility Model Content

[0004] This utility model provides a motor assembly structure for a vacuum cleaner, which solves the defect of manual gear pressing in the prior art, which leads to the inability to achieve a stable and uniform pressing depth of the gears, thus affecting the product qualification rate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a motor assembly structure for a vacuum cleaner, comprising: Support platform; The feeding assembly includes a movable plate movably disposed on the top of the support platform, a carrier plate fixed on the top of the movable plate, and a limiting mechanism disposed on the top of the carrier plate, the limiting mechanism being used to limit the built-in motor. The pressing assembly includes a pressing frame mounted above the feeding assembly, a lifting plate vertically mounted at the bottom of the pressing frame, and a pressing mechanism fixed at the bottom of the lifting plate. The pressing mechanism is used to press the gear onto the motor shaft.

[0006] Ideally, the limiting mechanism includes a carrier groove formed on the top of the carrier plate, a limiting groove circumferentially arranged on the side wall of the carrier groove, and a limiting post inserted into the limiting groove, with the motor placed in the carrier groove and abutting against the limiting post.

[0007] Optimally, the pressing mechanism includes a fixed plate fixed to the bottom of the lifting plate, a pressing sleeve fixed to the bottom of the fixed plate, a slot formed on the side of the pressing sleeve near the fixed plate, a through groove formed at the bottom of the slot and penetrating the pressing sleeve, an inner pressing column locked in the slot, and an outer pressing column integrally connected to the bottom of the inner pressing column and penetrating the through groove.

[0008] Optimally, the feeding assembly further includes a first cylinder mounting plate and a second cylinder mounting plate fixed at intervals on the top of the support platform, a linear cylinder fixed on the first cylinder mounting plate and the second cylinder mounting plate, a connecting plate fixed on one side of the moving plate and connected to the linear cylinder, and an avoidance groove formed at the bottom of the moving plate.

[0009] Optimally, the feeding assembly further includes a slide rail fixed to the top of the support platform and a slider slidably mounted on the slide rail, with the moving plate fixed to the slider.

[0010] Optimally, the feeding assembly further includes a first support plate and a second support plate fixed to the top of the support platform, a first limiting rod fixed to the first support plate and cooperating with the movable plate, a contact plate fixed to one side of the movable plate, and a second limiting rod fixed to the second support plate and cooperating with the contact plate.

[0011] Optimally, the pressing assembly further includes a guide post fixed between the support platform and the pressing frame, a guide sleeve sleeved on the guide post and fixed to the lifting plate, and a pressing cylinder fixed to the top of the pressing frame and connected to the lifting plate.

[0012] Optimally, the pressing assembly further includes a third limiting rod that is height-adjustably mounted on the top of the support platform and cooperates with the lifting plate.

[0013] Optimally, the pressing assembly further includes a threaded rod fixed to the bottom of the third limiting rod and screwed onto the support platform, and a limiting nut screwed onto the threaded rod and abutting against the upper surface of the support platform.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model's motor assembly structure for vacuum cleaners uses a movable carrier plate to support and position the motor and gears, and utilizes pressure columns for axial pressing. This achieves precise and consistent control of the gear pressing depth, eliminates differences caused by manual operation, ensures consistent product quality, and improves the product assembly qualification rate.

[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0017] like Figure 1 , 2 The diagram shows a schematic of the motor assembly structure for a vacuum cleaner according to this invention, typically used to press-fit gears onto the output shaft of a motor. The assembly structure includes a support platform 1, a feeding assembly mounted on top of the support platform 1, and a pressing assembly mounted above the feeding assembly. The feeding assembly carries the motor and gear to be pressed, and the pressing assembly presses the gear placed on the motor output shaft into place.

[0018] The feeding assembly includes a slide rail 2, a slider 3, a moving plate 4, a carrier plate 5, a carrier groove 6, a limiting groove 7, a limiting post 8, a clearance groove 9, a first cylinder mounting plate 10, a second cylinder mounting plate 11, a linear cylinder 12, a connecting plate 13, a first support plate 14, a first limiting rod 15, a second support plate 16, a second limiting rod 17, and a contact plate 18. There are two slide rails 2, which are fixed to the top of the support platform 1 by screws, and the two slide rails 2 are spaced apart on the upper surface of the support platform 1. The slider 3 is slidably mounted on the slide rail 2, and the moving plate 4 is fixed to the top of the slider 3 by screws. By setting up the mutually cooperating slide rails 2 and slider 3, the stability of the moving plate 4 is improved.

[0019] like Figure 3 As shown, the first cylinder mounting plate 10 and the second cylinder mounting plate 11 are fixed to the top of the support platform 1 by screws and are spaced apart. The first cylinder mounting plate 10 and the second cylinder mounting plate 11 are both corner plates (the corner plate is composed of two plates that are integrally connected and perpendicular to each other, one of which is fixed to the top of the support platform 1 by screws, and the other plate is perpendicular to the support platform 1).

[0020] The two ends of the linear cylinder 12 are fixed to the first cylinder mounting plate 10 and the second cylinder mounting plate 11, respectively. A commercially available Airtac series cylinder can be used for the linear cylinder 12. The connecting plate 13 is fixed to one side of the movable plate 4 by screws and is connected to the piston rod of the linear cylinder 12. The linear cylinder 12 drives the movable plate 4 to move. A clearance groove 9 is formed on the lower surface of the movable plate 4. When the movable plate 4 reciprocates, it avoids the position of the second cylinder mounting plate 11 below, preventing interference.

[0021] like Figure 4 As shown, the carrier plate 5 is fixed to the top of the movable plate 4 by screws. When the linear cylinder 12 moves the movable plate 4, the movable plate 4 will move the carrier plate 5 synchronously, thereby transferring the motor. A slot 6 is formed on the top of the carrier plate 5 to hold the motor to be assembled. Limiting slots 7 are arranged around the side walls of the slot 6, with an included angle of 120° between every two adjacent sets of limiting slots 7. Limiting posts 8 are inserted into the limiting slots 7 and then fixed to the carrier plate 5 by welding. During actual assembly, the operator places the motor in the slot 6. At this time, the outer wall of the motor housing abuts against the limiting posts 8, which limit the internal motor and prevent motor displacement during press-fitting.

[0022] The first support plate 14 is fixed to the support platform 1 by screws. The first limiting rod 15 is fixed to the first support plate 14 and cooperates with the side wall of the movable plate 4. The first limiting rod 15 limits the pressing position of the movable plate 4 to ensure that the movable plate 4 is directly below the pressing position and avoids misalignment during pressing.

[0023] The second support plate 16 is fixed to the top of the support platform 1 by screws. The second limiting rod 17 is fixed to the second support plate 16. The contact plate 18 is fixed to one side of the moving plate 4 by welding and cooperates with the second limiting rod 17. The second limiting rod 17 limits the material picking position of the moving plate 4, making it convenient for the operator to pick up and put down materials.

[0024] The pressing assembly includes guide posts 19, guide sleeves 20, lifting plates 21, top plates 22, pressing cylinders 23, first fixing plates 24, second fixing plates 25, pressing sleeves 26, slots 27, through slots 28, inner pressing posts 29, outer pressing posts 30, threaded rods 31, limit nuts 32, and third limit rods 33. There are two guide posts 19, which are vertically fixed to the top of the support platform 1 by welding. The top plate 22 is fixed to the top of the two guide posts 19 by welding. The cylinder body of the pressing cylinder 23 is fixed to the top plate 22 by screws. The piston rod of the pressing cylinder 23 passes through the through hole of the top plate 22 and is connected to the lifting plate 21 through a floating joint. The pressing cylinder 23 drives the lifting plate 21 to descend.

[0025] To improve the stability of the lifting plate 21, the guide sleeve 20 is embedded on both sides of the lifting plate 21 and sleeved on the guide column 19. When the lifting plate 21 is lifted, the guide sleeve 20 is lifted synchronously along the axial direction of the guide column 19.

[0026] like Figure 5 As shown, the first fixing plate 24 is fixed to the bottom of the lifting plate 21, and the second fixing plate 25 is fixed to the bottom of the first fixing plate 24. The pressure sleeve 26 is fixed to the bottom of the second fixing plate 25 by screws. The slot 27 is opened on the side of the pressure sleeve 26 near the second fixing plate 25, and the through groove 28 is opened at the bottom of the slot 27 and passes through the pressure sleeve 26 vertically (the diameter of the slot 27 is larger than the diameter of the through groove 28).

[0027] The inner pressure column 29 is inserted into the slot 27 of the pressure sleeve 26, and the outer pressure column 30 is integrally connected to the bottom of the inner pressure column 29 and passes through the through slot 28. The lifting plate 21 is driven to descend by the lowering cylinder 23, and the gear is pressed onto the output shaft of the motor through the outer pressure column 30. The pressure sleeve 26 protects the inner pressure column 29 and the outer pressure column 30 to prevent deformation of the pressure column.

[0028] The top of the support platform 1 has a threaded hole, and the threaded rod 31 is screwed into the threaded hole of the support platform 1. The third limiting rod 33 is fixed to the top of the threaded rod 31 and is set in the vertical direction. By screwing the threaded rod 31, the height of the third limiting rod 33 can be adjusted. When the lifting plate 21 descends, the third limiting rod 33 limits the descent of the lifting plate 21 to prevent it from descending too far and damaging the motor. By setting the mutually cooperating threaded hole and threaded rod 31, the operator can easily adjust the height of the third limiting rod 33 according to the pressing depth.

[0029] The limiting nut 32 is screwed onto the threaded rod 31 and abuts against the upper surface of the support platform 1 to limit the threaded rod 31 after it has been screwed on.

[0030] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
