Description

Technical Field

[0001] The utility model relates to the technical field of rotor assembly, in particular to an assembly mechanism for a rotor housing and a partition frame. Background Technique

[0002] In recent years, with the rapid development of power electronics technology, microelectronics technology, and new motor control theory, brushless DC motors have been rapidly developed and widely used. The magnetic tiles of existing brushless DC motors are fixed on the inner wall of the rotor housing by glue. To ensure that the intervals between adjacent magnetic tiles are equal, fixed blocks are usually placed between two adjacent magnetic tiles as spacing media. The existing fixed blocks are mainly inserted and installed manually. This method mainly depends on the experience and proficiency of workers, with low assembly efficiency. Moreover, during the insertion process of the fixed blocks, the magnetic tiles are likely to shift in position, resulting in uneven distribution of the glue layer between the magnetic tiles and the rotor housing, thus reducing the overall quality of the motor and affecting the output performance and service life of the motor. Content of the Utility Model

[0003] The utility model aims to provide an assembly mechanism for a rotor housing and a partition frame to improve the installation efficiency and installation accuracy of the partition frame in the rotor housing, thereby improving the installation quality of subsequent magnetic tiles.

[0004] To achieve the above object, the utility model adopts the following technical scheme: An assembly mechanism for a rotor housing and a partition frame includes a support frame, a conveying mechanism, and a feeding mechanism arranged on the support frame. The feeding mechanism is located above the conveying mechanism. The conveying mechanism is used for horizontally conveying the rotor housing, and the feeding mechanism is used for vertically conveying the partition frame. The conveying mechanism includes a conveying sprocket and a conveying tooling located on the conveying sprocket. The feeding mechanism includes a feeding frame and an intermittent feeding assembly. The intermittent feeding assembly includes a first control cylinder and a second control cylinder distributed vertically. Blocks are arranged at the ends of the output shafts of the first control cylinder and the second control cylinder.

[0005] The principle and advantages of this solution are:

[0006] In actual application, this solution realizes the automatic feeding of the rotor housing and the partition frame through the conveying mechanism and the feeding mechanism respectively. Through the cooperation between the conveying tooling and the intermittent feeding component, the placement position of the partition frame is accurately controlled in both the horizontal and vertical dimensions to achieve precise automatic assembly. Compared with manual operation, it significantly improves the assembly efficiency of the rotor housing and the partition frame, reduces the dependence on the experience and proficiency of workers, and makes the production process more standardized and efficient. At the same time, this solution installs the partition frame before installing the magnetic sheet. Compared with the prior art of first installing the magnetic sheet and then inserting the fixing block, this solution greatly reduces the risk of subsequent magnetic sheet position deviation, ensures the uniformity of the spacing between adjacent magnetic sheets, and also avoids the problem of uneven distribution of the adhesive layer between the magnetic sheet and the rotor housing that may be caused by manual operation. The uniform distribution of the adhesive layer helps to enhance the fixing strength of the magnetic sheet, improving the assembly accuracy and overall quality of the motor.

[0007] Furthermore, clamping components for positioning the rotor housing are symmetrically arranged on both sides of the support frame. The clamping components include driving cylinders and clamping blocks.

[0008] The position of the rotor housing on the conveying tooling is further adjusted and determined through the clamping components to ensure precise alignment between the rotor housing and the partition frame, realizing precise assembly of the two and guaranteeing production efficiency.

[0009] Furthermore, stop components for stopping the conveying tooling are evenly arranged on the support frame. The stop components include sensors, stop cylinders, and stop seats arranged at the end of the output shaft of the stop cylinders.

[0010] Through the cooperation of the sensors, stop cylinders, and stop seats, it is ensured that each conveying tooling stops moving when it reaches below the feeding mechanism for the assembly process. And compared with the frequent start and stop of the entire conveying sprocket, which consumes time and energy and exacerbates the start and stop wear of components, intercepting the conveying tooling through the stop components can effectively ensure production continuity and be more economical.

[0011] Furthermore, guide rods are circumferentially and evenly distributed on the feeding frame, and the guide rods cooperate with the positioning notches on the partition frame.

[0012] The cooperation between the above guide rods and the positioning notches on the partition frame ensures that the installation positions of the partition frames in each rotor housing are consistent, which is conducive to realizing the standardization of subsequent magnetic sheet assembly and ensuring the consistency of product quality.

[0013] Furthermore, a jacking component is arranged below the support frame corresponding to the feeding frame. The jacking component is used to jack up the conveying tooling and the rotor housing thereon.

[0014] The transfer tooling and the rotor housing thereon are lifted upward by the lifting assembly to between the clamping assemblies on both sides, so that the transfer tooling is disengaged from the transfer sprocket, facilitating the effective clamping of the rotor housing by the clamping assemblies, achieving secondary positioning, and avoiding the shaking and offset of the rotor housing caused by the relative movement between the transfer tooling and the transfer sprocket during the assembly of the partition frame, which may lead to assembly errors and affect the assembly efficiency and quality.

[0015] Further, the end of the clamping block facing the partition frame is V-shaped.

[0016] The V-shaped end of the clamping block can naturally guide the centering of the rotor housing, which helps the rotor housing to be positioned quickly and accurately. At the same time, the V-shaped structure can be applied to the clamping of rotor housings of different specifications and sizes, eliminating the need for frequent replacement of the clamping block and improving production efficiency.

[0017] Further, a sliding assembly is provided between the clamping block and the end of the output shaft of the driving cylinder. The sliding assembly includes a slide rail and a sliding seat, and the sliding seat is connected to the output shaft of the driving cylinder.

[0018] With the sliding assembly as an intermediate transmission structure, moving along the slide rail is beneficial to ensuring the movement stability of the clamping block and preventing position offset, which may prevent the rotor housing from being adjusted to the correct assembly position.

[0024] The following is a further detailed description through specific embodiments:

[0025] The reference numerals in the drawings of the specification include: a partition frame 1, an annular bottom plate 11, partition plates 12, positioning notches 13, a support frame 2, a conveying mechanism 3, conveying sprockets 31, a conveying tooling 32, a feeding mechanism 4, a feeding frame 41, guide rods 42, a first control cylinder 43, a second control cylinder 44, a stop block 45, a stopping assembly 5, an inductor 51, a stopping cylinder 52, a stopping seat 53, a clamping assembly 6, a driving cylinder 61, clamping blocks 62, a lifting assembly 7, a lifting cylinder 71, a transmission plate 72, a sliding assembly 8, a sliding seat 81, and a slide rail 82.

[0026] As shown in the Figure 1 accompanying drawings, the structure schematic diagram of the partition frame 1 is shown. The partition frame 1 includes an annular bottom plate 11 and partition plates 12 vertically and annularly arranged on the annular bottom plate 11. A plurality of arc-shaped positioning notches 13 are provided on the annular bottom plate 11.

[0027] The embodiment is basically as shown in the Figures 2 - 5 accompanying drawings: An assembly mechanism for a rotor housing and a partition frame includes a support frame 2, a conveying mechanism 3 and a feeding mechanism 4 arranged on the support frame 2. The feeding mechanism 4 is located above the conveying mechanism 3. The conveying mechanism 3 is used for horizontally conveying the rotor housing, and the feeding mechanism 4 is used for vertically conveying the partition frame 1. The conveying mechanism 3 includes conveying sprockets 31 and a conveying tooling 32 located on the conveying sprockets 31. The conveying sprockets 31 are driven by a motor to perform a rotary motion. The conveying sprockets 31 and the conveying tooling 32 have a rolling friction therebetween. The main structure of the conveying tooling 32 is a rectangular tray. The feeding mechanism 4 includes a feeding frame 41 and an intermittent feeding assembly. The intermittent feeding assembly includes a first control cylinder 43 and a second control cylinder 44 distributed in sequence from top to bottom. Stopping blocks 45 are provided at the end parts of the output shafts of the first control cylinder 43 and the second control cylinder 44. The stopping block 45 on the first control cylinder 43 has a U-shaped structure, which is convenient for the stopping block 45 to be inserted between adjacent partition plates 12. The first control cylinder 43 and the second control cylinder 44 are controlled by a PLC program to perform an interleaved motion to realize the intermittent feeding of the partition frame 1.

[0028] Guide rods 42 are circumferentially and evenly distributed on the feeding frame 41. The guide rods 42 protrude into the feeding frame 41. The guide rods 42 cooperate with the positioning notches 13 on the partition frame 1. In this way, the installation positions of the partition frames 1 in each rotor housing are ensured to be consistent, which is beneficial to realizing the standardization of subsequent magnetic sheet assembly and ensuring the consistency of product quality.

[0029] As Figure 4As shown in the figure, a number of stop components 5 for stopping the transfer tooling 32 are evenly fixed on the support frame 2. The stop components 5 are located at the bottom of the transfer sprocket 31. The stop component 5 includes an inductor 51, a stop cylinder 52, and a stop seat 53 provided at the end of the output shaft of the stop cylinder 52. The induction signal of the inductor 51 is transmitted to the PLC program, and the stop cylinder 52 is controlled and driven by the PLC program. By cooperating the inductor 51 with the stop cylinder 52 and the stop seat 53, it is ensured that each transfer tooling 32 stops moving when it reaches below the feeding mechanism 4 for the assembly process. Moreover, compared with the frequent start and stop of the whole transfer sprocket, which consumes time and energy and aggravates the start and stop wear of components, stopping the transfer tooling 32 by the stop component 5 can effectively ensure production continuity and be more economical.

[0030] Clamping components 6 for positioning the rotor housing are symmetrically provided on both sides of the support frame 2. The clamping component 6 includes a driving cylinder 61 and a clamping block 62. The end of the clamping block 62 facing the partition frame 1 is V-shaped; by further adjusting and determining the position of the rotor housing on the transfer tooling 32 through the clamping component 6, it is ensured that the rotor housing is accurately aligned with the partition frame 1 to achieve precise assembly of the two. At the same time, the V-shaped structure at the end of the clamping block 62 can have a guiding effect on the rotor, which helps the rotor housing to be quickly and accurately positioned. Moreover, the V-shaped structure can be suitable for clamping rotor housings of different specifications and sizes, without the need to frequently replace the clamping block 62, improving production efficiency.

[0031] The support frame 2 is also provided with a lifting component 7 at the position corresponding to the feeding frame 41 below. The lifting component 7 is used to lift the transfer tooling 32 and the rotor housing thereon. The lifting component 7 includes a lifting cylinder 71 fixed on the support frame 2. The end of the output shaft of the lifting cylinder 71 is connected to a transmission plate 72. By the lifting component 7, the rotor housing is lifted upward between the clamping components 6 on both sides, so that the transfer tooling 32 is separated from the transfer sprocket 31, which is convenient for the clamping component 6 to effectively clamp the rotor housing for secondary positioning, avoiding assembly errors caused by the shaking and offset of the rotor housing due to the relative movement between the transfer tooling 32 and the transfer sprocket 31 all the time, and ensuring the assembly quality.

[0032] Preferably, a sliding component 8 is further provided between the clamping block 62 and the end of the output shaft of the driving cylinder 61. The sliding component 8 includes a slide rail 82 and a sliding seat 81. The sliding seat 81 is fixed on the output shaft of the driving cylinder 61; by using the sliding component 8 as an intermediate transmission structure, the movement of the clamping block 62 along the slide rail 82 is beneficial to ensure the movement stability of the clamping block 62 and prevent position deviation so that the rotor housing cannot be adjusted to the correct assembly position.

[0033] The specific implementation process is as follows:

[0034] In specific applications, the rotor housing is clamped by a manipulator and placed on the initial transfer tooling 32. The transfer sprocket 31 is driven by a motor to rotate, and drives the transfer tooling 32 and the rotor housing thereon to perform horizontal transportation through rolling friction. When the transfer tooling 32 moves to the inductor 51, the inductor 51 transmits an induction signal to the PLC program. The PLC program sends a driving signal to the stop cylinder 52, the first control cylinder 43, and the second control cylinder 44. The stop cylinder 52 raises the stop seat 53 to position the rotor housing directly below the feeding rack 41. At the same time, the second control cylinder 44 drives the block 45 thereon to contract, causing the partition frame 1 to fall into the rotor housing. Then, the second control cylinder 44 drives the block 45 to reset to prevent the partition frame 1 from continuing to fall. After the second control cylinder 44 resets, the first control cylinder 43 drives the block 45 thereon to contract, and the partition frame 1 at the bottom of the feeding rack 41 falls onto the block 45 of the second control cylinder 44 to wait for the next assembly. After the rotor housing and the partition frame 1 are assembled, the stop cylinder 52 drives the stop seat 53 to descend, and the transfer tooling 32 continues to move to the next station driven by the friction of the transfer sprocket 31; the subsequent rotor housings are driven by the transfer tooling 32 to repeat the above operation process for the assembly of the partition frame 1.

[0035] The above are only embodiments of the present invention, and common general technical solutions and / or characteristics in the solutions are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application shall be subject to the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
