Description

Technical Field

[0001] This invention belongs to the field of motor assembly technology, specifically an automated anti-misalignment pressing device for motor stator and plastic housing. Background Technology

[0002] In the motor assembly process, the coaxial pressing of the motor stator and the plastic housing is a key process. Usually, the motor stator is first positioned and fixed on the worktable, and then the plastic housing is aligned and placed above the stator. The pressing mechanism drives the housing to move downward along the axis, so that the stator is smoothly pressed into the inner cavity of the plastic housing to complete the reliable assembly of the components.

[0003] Most existing press-fitting devices adopt a split positioning structure, which requires separate clamping and fixing of the motor stator and the plastic shell. This not only makes the positioning process cumbersome and the work efficiency low, but also easily leads to misalignment of the stator and the shell due to the two positioning errors, resulting in problems such as misalignment, jamming, or even cracking of the plastic shell. It is difficult to meet the accuracy and efficiency requirements of automated continuous production. Summary of the Invention

[0008] Preferably, the bottom of the base is symmetrically and fixedly connected to two guide rods, and two guide plates are movably sleeved on the outside of the two guide rods. A drive motor is fixedly installed at the bottom of the base, and a drive shaft is fixedly connected to the drive motor. The bottom end of the drive shaft is fixedly connected to a chassis located between the two guide plates. Two movable rods are rotatably connected at equal angles at the bottom of the chassis. The ends of the two movable rods away from the chassis are rotatably connected to the bottom of the two guide plates respectively.

[0009] Preferably, each of the two sliding frames is fixedly connected to a column at its bottom, and each of the two columns is fixedly connected to a base block at its bottom end. Each of the two guide plates is provided with a through hole, and each of the two columns passes through the two through holes respectively.

[0010] Preferably, two annular grooves are symmetrically fixedly sleeved on the inner side of the through hole, and multiple balls are provided at equal angles on the inner side of the two annular grooves, with each ball abutting against the outer wall of the column.

[0011] Preferably, the top of the base is symmetrically fixedly connected to two guide columns, the lifting plate is movably sleeved on the outside of the two guide columns, a top plate is fixedly connected between the top ends of the two guide columns, a hydraulic cylinder is fixedly installed at the bottom of the top plate, and the top of the lifting plate is fixed to the output end of the hydraulic cylinder.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this invention, starting the drive motor can move two guide plates, which facilitates the two V-shaped clamping plates to come closer together and clamp the motor stator on the top of the base. At the same time, it can also make the two V-shaped clamping plates come closer together and clamp the plastic shell on the bottom of the lifting plate, which facilitates the quick fixation of the motor stator and the plastic shell. By starting the hydraulic cylinder, the lifting plate can be driven to descend stably, which facilitates the smooth pressing of the motor stator into the inner cavity of the plastic shell.

[0017] 2. This invention, through the cooperation between the mounting plate and the sliding frame, as well as the bolts and the abutment frame, allows the V-shaped clamping plate one to be replaced as needed. This facilitates the V-shaped clamping plate two to clamp the motor stator while also clamping the plastic housing, thus making it easy to adapt to the press-fitting between motor stators and plastic housings of different specifications.

[0018] 3. The invention allows the two V-shaped clamps to be pushed downwards by the descent of the plastic shell, which facilitates the removal of the two V-shaped clamps from the outside of the motor stator, thereby making it easier to avoid the plastic shell for smooth pressing.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example 1, by Figures 1-7 The present invention relates to an automated anti-misalignment pressing device for a motor stator and a plastic housing, comprising a base 1, a plurality of pillars 6 fixedly connected to the bottom of the base 1, guide grooves 5 on both sides of the top of the base 1, a fixing mechanism 2 on the base 1, and a replacement mechanism 3 and a lifting assembly 4 on the fixing mechanism 2.

[0031] In Embodiment 2, based on Embodiment 1, the fixing mechanism 2 includes a lifting plate 201 horizontally positioned above the base 1. Two V-shaped clamping plates 203 are symmetrically arranged at the bottom of the lifting plate 201. Two V-shaped clamping plates 204 are arranged above each of the two guide grooves 5. Guide plates 207 are slidably connected to the inner sides of each of the two guide grooves 5. The two V-shaped clamping plates 204 are respectively installed on the sides of the two guide plates 207 that are close to each other. A sliding groove 2016 is provided at the bottom of the lifting plate 201. A sliding rod 2017 is fixedly connected to the inner side of the sliding groove 2016. Two sliding frames 208 are symmetrically and movably sleeved on the outer side of the sliding rod 2017. Two V-shaped clamps 203 are respectively installed on the sides of the two sliding frames 208 that are close to each other. Two guide rods 205 are symmetrically fixedly connected to the bottom of the base 1. Two guide plates 207 are movably sleeved on the outside of the two guide rods 205. A drive motor 2013 is fixedly installed at the bottom of the base 1. A drive shaft 2012 is fixedly connected to the drive motor 2013. The bottom end of the drive shaft 2012 is fixedly connected to a chassis 206 located between the two guide plates 207. Two movable rods 2014 are rotatably connected at equal angles to the bottom of the chassis 206. The two movable rods 2014 are away from the chassis 206. One end of each slide frame 208 is rotatably connected to the bottom of two guide plates 207. A column 2011 is fixedly connected to the bottom of each slide frame 208. A base block 2015 is fixedly connected to the bottom of each column 2011. Each guide plate 207 has a through hole 2018. Each column 2011 passes through one of the two through holes 2018. Two annular grooves 2019 are symmetrically fitted inside the through holes 2018. Multiple balls 2020 are evenly spaced on the inner sides of the two annular grooves 2019. Each ball 2020 abuts against the outer wall of the column 2011, passing through the through hole 2018 and the annular groove. The cooperation between body 2019 and ball bearing 2020 avoids direct contact between guide plate 207 and column 2011, thus avoiding affecting the relative movement between them. Two guide columns 202 are symmetrically fixedly connected to the top of base 1. Lifting plate 201 is movably sleeved on the outside of the two guide columns 202. A top plate 2010 is fixedly connected between the top ends of the two guide columns 202. A hydraulic cylinder 209 is fixedly installed at the bottom of the top plate 2010. The top of lifting plate 201 is fixed to the output end of hydraulic cylinder 209. The two guide columns 202 are used to limit and guide the lifting plate 201, playing a role in preventing misalignment.

[0032] First, place the motor stator and the plastic housing on the top of the base 1 and the bottom of the lifting plate 201 respectively, so that the motor stator is located between the two V-shaped clamps 204 and the plastic housing is located between the two V-shaped clamps 203. Then, start the drive motor 2013, drive the drive shaft 2012 to rotate, and drive the chassis 206 to rotate. Through the two movable rods 2014, drive the two guide plates 207 to slide along the two guide round rods 205 respectively, while the two V-shaped clamps 204 move closer to each other.

[0033] When the two guide plates 207 move, the two columns 2011 drive the two sliding frames 208 to slide along the sliding rod 2017 respectively. At the same time, the two V-shaped clamps 203 move closer to each other. When the two V-shaped clamps 204 clamp the motor stator, the two V-shaped clamps 203 clamp the plastic shell, thus achieving rapid fixation of the motor stator and the plastic shell.

[0034] When the hydraulic cylinder 209 is activated, it drives the lifting plate 201 to slide downwards along the two guide columns 202, and drives the plastic shell to descend, finally pressing the motor stator smoothly into the inner cavity of the plastic shell.

[0035] In Example 3, based on Example 1, the replacement mechanism 3 includes a mounting plate 301 fixed to the outside of the V-shaped clamp 203. An abutment frame 302 is fixedly sleeved on the outside of the mounting plate 301. The mounting plate 301 passes through the sliding frame 208, and the abutment frame 302 abuts against the sliding frame 208. A bolt 303 is installed between the mounting plate 301 and the sliding frame 208.

[0036] First, the mounting plate 301 is inserted through the slide frame 208 until the abutment frame 302 abuts against the slide frame 208. Then, the bolts 303 are tightened to fix the mounting plate 301 to the slide frame 208, thus realizing the installation of the V-shaped clamp 203. When the bolts 303 are loosened, the V-shaped clamp 203 can be disassembled and replaced. When the V-shaped clamp 204 clamps the motor stator, the V-shaped clamp 203 can clamp the plastic shell, which can adapt to the press-fitting between motor stators and plastic shells of different specifications.

[0037] In Example 4, based on Example 1, the lifting assembly 4 includes a side plate 401 fixed to the outside of the guide plate 207. Two L-shaped round rods 404 are symmetrically fixedly connected between the side plate 401 and the guide plate 207. A movable plate 402 is movably sleeved between the two L-shaped round rods 404. A connecting plate 405 is fixedly connected between the movable plate 402 and the V-shaped clamping plate 204. Two springs 406 are symmetrically fixedly connected between the movable plate 402 and the side plate 401. The two springs 406 are respectively sleeved on the outside of the two L-shaped round rods 404. Limiting rings 403 are fixedly sleeved on the outside of each of the two L-shaped round rods 404. The movable plate 402 abuts against the bottom of the two limiting rings 403.

[0038] When the lifting plate 201 lowers the plastic shell, it pushes the two V-shaped clamps 204 downwards, so that the two V-shaped clamps 204 pass through the two guide grooves 5 respectively, thereby removing the two V-shaped clamps 204 from the outside of the motor stator, thus avoiding the plastic shell for smooth pressing.

[0039] When the V-shaped clamp 204 descends, the connecting plate 405 drives the movable plate 402 to slide downward along the two L-shaped round rods 404. At this time, both springs 406 are compressed. When the lifting plate 201 rises, the V-shaped clamp 204 can rise and reset under the action of the spring force of the spring 406.
