Description

Technical Field

[0001] This utility model relates to the field of stator processing technology, and in particular to a stator housing removal and positioning fixture. Background Technology

[0002] The existing motor includes a housing, rotor, stator, shaft, and end cover. The housing is a hollow cylindrical structure with one open side. Both the stator and rotor are housed within the housing, with the stator fixed inside. Several locking blocks, spaced circumferentially along the outer wall of the housing, are integrally injection-molded for securing the housing. Each locking block has through-holes for bolts and a recessed groove on its top surface for the bolt head to be inserted. The rotor rotatably mounts within the stator. The end cover seals the open side of the housing, enclosing the rotor within it. The shaft is fixed to the rotor, with one end of the shaft extending beyond the end cover. In this type of motor, the housing and stator are integrally injection-molded. Before injection molding, the stator is manufactured independently and then placed in an injection mold to integrally mold the housing. After the housing and stator are injection-molded, the injection molding process needs to be inspected for quality. If the injection molding is found to be substandard, the housing is placed on a machining machine and ground down using a grinding wheel. The stator is then re-molded in the injection mold.

[0003] An existing machining machine for processing housings includes a machining table. The top surface of the machining table is equipped with several clamping blocks that hold the housings in place. These clamping blocks are evenly spaced circumferentially, forming a clamping space within which the housing is placed. The clamping blocks are mounted on the machining table in a manner that allows them to move relative to or away from each other towards the center of the clamping space. A grinding head, capable of vertical movement and circumferential rotation, is mounted above the clamping space on the machining table. In operation, the housing is first placed in the clamping space and held in place by the clamping blocks, with the open side of the housing facing upwards. The grinding head descends to the open end of the housing and grinds its surface. After grinding, the grinding head descends to the outer side wall of the housing and performs circumferential grinding. During side grinding, the operator frequently rotates the housing to ensure the clamping parts of the blocks are ground. After side grinding, the housing is flipped over so that the open side faces downwards, and the grinding head then grinds the unground end face of the housing. However, this polishing method requires stopping the machine and having the worker rotate the shell circumferentially when polishing the sides of the shell, which is time-consuming. Furthermore, the entire shell must be polished before the next shell can be polished, resulting in low work efficiency.

[0004] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a positioning fixture for removing stator housings, so as to solve the problem of low working efficiency of existing housings during grinding.

[0006] To achieve its purpose, this utility model adopts the following technical solution:

[0007] A stator housing removal positioning fixture includes a processing table with a positioning structure for positioning and mounting the housing. The positioning structure has a first positioning structure and a second positioning structure, which are arranged laterally at intervals. The first positioning structure has a support structure and a clamping structure. The support structure consists of several support blocks that are aligned one-to-one with each snap-fit ​​component of the housing and on which the snap-fit ​​components are placed. The clamping structure has several clamping rods suspended horizontally above each support block and several corresponding drive devices that control the rotation and lifting of the clamping rods. The top surface of the processing table has a mounting hole at the second positioning structure. Several circumferentially distributed limiting rods are erected inside the processing table, with their lower ends inside the processing table and their upper ends passing through the mounting hole and out of the top surface of the processing table. A translation drive device is installed on the processing table to control the translation of each limiting rod towards and away from the center of the mounting hole. The mounting hole, the limiting rods, and the translation drive device constitute the second positioning structure.

[0008] The aforementioned processing table is a hollow square base.

[0009] The top surface of the aforementioned processing table has an embedding through hole at the first positioning structure, into which the end face of the outer shell is partially embedded. Each support block is located outside the embedding through hole and is evenly spaced around it.

[0010] The aforementioned support block is in the form of a cylindrical block, which matches the diameter of the bolt through hole of the snap-fit ​​block on the outer shell. A support protrusion ring is provided on the outer side wall of the aforementioned cylindrical block for the snap-fit ​​block of the outer shell to support.

[0011] The end of the clamping rod near the embedded through hole is locked with a clamping block that is vertically set and whose lower end can be embedded in the receiving groove of the snap-fit ​​block. The end of the clamping rod away from the embedded through hole is equipped with the aforementioned driving device.

[0012] The aforementioned driving device is a rotary pressing cylinder, which is vertically installed in the hollow space of the processing table. The upper end of the rotary pressing cylinder extends out of the top surface of the processing table, and the output end of the rotary pressing cylinder is set upward and fixedly engaged with the clamping rod.

[0013] The aforementioned mounting hole is a circular through hole, and the aforementioned limiting rod is a cylindrical rod body. There are three limiting rods, which are evenly spaced around the periphery.

[0014] The aforementioned translation drive device has a swing arm linkage mechanism that drives each limiting rod to move towards and away from the center of the mounting hole, and a swing arm drive device that controls the movement of the swing arm linkage mechanism. The aforementioned swing arm linkage mechanism is located in the hollow space of the processing table, and the aforementioned swing arm drive device is located outside the processing table.

[0015] The aforementioned swing arm linkage mechanism includes a swing arm, a rotary disk, a connecting rod, and a driving rod. The swing arm driving device is a translation cylinder, with the left-right direction defined by the transverse arrangement of the first and second positioning structures. The second positioning structure is located on the right side. The translation cylinder is horizontally fixed to the outside of the front side of the processing table along the left-right direction, and its output end faces right. The swing arm has a first connecting rod and a second connecting rod. The first connecting rod is inclined to the right from front to back, and its front end is connected to the output end of the translation cylinder. The second connecting rod is inclined to the left from front to back, and its rear end is connected to the front end of the first connecting rod. The rear end of the second connecting rod is located to the left and rear of the front end of the first connecting rod, and its rear end is connected to the rotary disk. The rotating disk is connected to the inner top surface of the processing table. A connecting cylinder that runs vertically through the mounting hole is fitted inside the mounting hole. The bottom surface of the connecting cylinder is locked to the rotating disk. The rotating disk has a vertically through opening at the position of the connecting cylinder. The limiting rod is vertically positioned within the hollow cavity and opening of the connecting cylinder. The lower end of the limiting rod is connected to the first end of the driving rod. The second end of the driving rod extends out of the rotating disk and is suspended below the inner top surface of the processing table. The connecting shaft is located between the driving rod and the rotating disk. The first end of the connecting shaft is connected to the first end of the driving rod. The second end of the connecting shaft is connected to the rotating disk. The connecting shaft and the driving rod form a flared structure that gradually expands from the inside to the outside.

[0016] The top surface of the processing table has several mounting slots spaced apart in the circumferential direction and connected to the mounting holes at the second positioning structure. The bottom of the mounting slot is provided with a limiting rod that can move horizontally along the radial direction of the mounting hole and can be pressed against the outer wall of the outer shell.

[0017] In this novel stator housing removal and positioning fixture, the housing is placed within the range of support blocks on the top surface of the processing table, with the open side of the housing facing upwards. Each support block passes through the bolt holes of the locking blocks on the housing, and the clamping structures are correspondingly pressed into the respective receiving grooves, thus achieving housing positioning. Then, the grinding head is lowered to the open end of the housing and the open end face is ground. After grinding, the grinding head is lowered to the outer side wall of the housing for circumferential grinding. After grinding the side wall of the housing... Next, move the outer casing and place it on the top surface of the processing table at the position corresponding to the mounting hole, with the open side of the outer casing facing down. Extend each limiting rod into the hollow cavity of the outer casing. Start the translation drive device, which drives each limiting rod to spread out and press against the inner side wall of the outer casing to limit the outer casing. Then, the grinding head grinds the un-grinded end face of the outer casing. After grinding, the translation drive device resets, the limiting rods come together, and the stator with the ground outer casing removed is taken out. Finally, the stator is put back into the injection mold for processing. Compared to existing technologies, this method offers several advantages. First, the supporting and clamping structures limit the outer shell by restricting the locking block. Since these structures do not obstruct the outer side of the shell, the grinding head does not need to rotate the shell when grinding its outer side and open end. The grinding head can separate the locking block from the shell by moving around the supporting and clamping structures, achieving overall shell grinding. Second, the outer side, open end, and un-grinded end face of the shell can be ground simultaneously by the first and second positioning structures on the processing table, resulting in higher grinding efficiency and overall work efficiency. Furthermore, the positioning of the shell by the first and second positioning structures during processing enhances the grinding precision. Attached Figure Description

[0019] Figure 2 This is another structural schematic diagram of the present invention. Detailed Implementation

[0020] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0021] Stator housing removal positioning fixture, such as Figures 1-2 As shown, the device includes a processing table 1, which is a hollow square base. The processing table 1 has a positioning structure for positioning and installing the outer shell. The positioning structure has a first positioning structure and a second positioning structure, which are arranged laterally at intervals. A grinding head that can be raised and lowered and rotated circumferentially is installed on the processing table above the first and second positioning structures. The specific structure of the grinding head and the method by which the grinding head grinds the outer shell inside the first and second positioning structures are well known to those skilled in the art and will not be described in detail here.

[0022] With the first and second positioning structures arranged laterally as the left-right direction, the second positioning structure is located on the right. The first positioning structure has a support structure and a clamping structure. The support structure consists of several support blocks 2 that are aligned one-to-one with each snap-fit ​​component of the outer shell and on which the snap-fit ​​components are placed. Specifically, the top surface of the processing table 1 has an embedded through hole 100 at the first positioning structure, into which the end face of the outer shell is partially embedded and connected to the hollow cavity of the processing table 1. Each support block 2 is located outside the embedded through hole 100 and is evenly spaced around it. The support block 2 is a cylindrical block, and the diameter of the bolt through hole of the snap-fit ​​component on the outer shell matches the diameter of the bolt through hole. The outer side wall of the cylindrical block has a support protrusion ring 21 for the snap-fit ​​component of the outer shell to support. The number of snap-fit ​​components of the outer shell matches the number of support blocks and corresponds one-to-one. There are three snap-fit ​​components of the outer shell and three support blocks 2. In application, the outer shell is placed within the range of each support block, so that the support block passes through the bolt holes of the snap-fit ​​block on the outer shell, until the snap-fit ​​block of the outer shell is stacked on the top surface of the support protrusion ring 21, so that the snap-fit ​​block of the outer shell is limited to the support block 2.

[0023] The clamping structure has several clamping rods 3 suspended horizontally above each support block 2 and several corresponding drive devices for controlling the rotation and lifting of the clamping rods 3. Specifically, the clamping rods 3 are strip-shaped rods that extend radially along the embedded through hole 100. The end of the clamping rod 3 near the embedded through hole 100 is locked with a clamping block 31 that is vertically set and whose lower end can be embedded in the receiving groove of the snap-fit ​​block. That is, the clamping block 31 and the support block 2 are arranged vertically opposite each other. The end of the clamping rod 3 away from the embedded through hole 100 is equipped with the drive device, which is a rotary pressing cylinder 4. The rotary pressing cylinder 4 is vertically installed in the hollow space of the processing table 1. The upper end of the rotary pressing cylinder 4 extends out of the top surface of the processing table 1, and the output end of the rotary pressing cylinder 4 is set upward and fixedly engaged with the clamping rod 3. When in use, the rotary pressing cylinder is activated, which drives the pressing block 31 to move down, pressing the pressing block onto the snap-fit ​​block, so that the outer shell is not easily shifted during processing; after processing is completed, the rotary pressing cylinder is reset, the pressing block 31 moves up and rotates out of the range above the support block 2, so that the next outer shell can be placed into the range of each support block 2.

[0024] The top surface of the processing table 1 has an installation hole 200 connected to the hollow cavity of the processing table at the second positioning structure. Several limiting rods 5 are erected in the processing table 1, which are circumferentially distributed and whose lower ends are inside the processing table 1 and whose upper ends pass through the installation hole 200 to the outside of the top surface of the processing table 1. Specifically, the installation hole 200 is a circular through hole and the limiting rod 5 is a cylindrical rod. Preferably, there are three limiting rods 5, which are evenly spaced around the top surface.

[0025] The processing table 1 is equipped with a translation drive device that controls the movement of each limiting rod 5 toward and away from the center of the mounting hole 200. The mounting hole 200, each limiting rod 5, and the translation drive device constitute the second positioning structure. Specifically, the translation drive device has a swing arm linkage mechanism 6 that drives each limiting rod 5 to move toward and away from the center of the mounting hole 200, and a swing arm drive device that controls the movement of the swing arm linkage mechanism 6. The swing arm linkage mechanism 6 is located in the hollow space of the processing table 1, and the swing arm drive device is located outside the processing table 1. That is, the swing arm linkage mechanism 6 has a swing arm 61, a rotary disk 62, a connecting rod 63, and a driving rod 64. The aforementioned swing arm drive device is a translation cylinder 7, which is horizontally fixed to the front side of the processing table 1 in the left-right direction, with its output end facing right. The swing arm 61 has a first connecting rod 611 and a second connecting rod 612. The first connecting rod 611 is inclined to the right from front to back, and its front end is connected to the output end of the translation cylinder 7. The second connecting rod 612 is inclined to the left from front to back, and its rear end is connected to the front end of the second connecting rod 612. The rear end of the second connecting rod 612 is located to the left rear of the front end of the first connecting rod 611, and its rear end is connected to the rotary disk 62. The turntable 62 is flat against the inner top surface of the processing table 1. A connecting cylinder 11, which extends vertically, is fitted inside the mounting hole 200. The bottom surface of the connecting cylinder 11 is locked to the turntable 62. The turntable 62 has a vertically extending opening at the position of the connecting cylinder 11. That is, the top surface of the turntable 62 has a locking groove recessed at the position of the connecting cylinder 11. The lower end of the connecting cylinder 11 extends into the locking groove, and the bottom surface of the connecting ventilation 11 is locked to the bottom of the locking groove. The limiting rod 5 is vertically positioned within the range of the connecting cylinder 11 and the opening. The connecting rod 63 and the driving rod 64 are both strip-shaped rods. The lower end of the limiting rod 5 is connected to the inner end of the driving rod 64. The connecting rod 64 extends out of the rotating disk 62 and is suspended below the inner top surface of the processing table. The connecting rod 63 is located between the connecting rod 64 and the rotating disk 62. The inner end of the connecting rod 63 is connected to the inner end of the connecting rod 64, and the outer end of the connecting rod 63 is connected to the rotating disk 62. The connecting rod 63 and the connecting rod 64 form a flared structure that gradually expands from the inside to the outside. That is, the inner end of the connecting rod has a first connecting hole that runs vertically through it, and the inner end of the connecting rod 64 has a second connecting hole that runs vertically through it at the position of the connecting rod 63. The connecting rod 64 is connected to the connecting rod by connecting bolts passing through the first connecting hole and the second connecting hole in sequence.In the initial state, the three limiting rods converge toward the center of the mounting hole 200, placing the outer casing on the top surface of the processing table 1. Simultaneously, the outer casing passes through the three limiting rods 5, and the output end of the translation cylinder 7 moves to the right, causing the front end of the swing arm 61 to move to the right. The rear end of the swing arm 61 drives the rotating disk 62 to rotate clockwise, and the connecting rod 62 rotates clockwise as well. This causes the inner end of the connecting rod 62 to drive the driving rod 64 to move, thereby causing the limiting rods 5 to move closer to the inner wall of the outer casing. Each limiting rod is relatively dispersed and presses against the inner wall of the outer casing, limiting the outer casing and making it difficult for it to move during processing. Conversely, after the outer casing is processed, the output end of the translation cylinder moves to the left, and the rotating disk rotates counterclockwise, thereby causing the limiting rods to converge relatively, making it easier to remove the outer casing.

[0026] In this novel stator housing removal positioning fixture, the housing is placed within the range of the support blocks 2 on the left side of the top surface of the processing table 1, with the open surface of the housing facing upwards. Each support block 2 passes through the bolt holes of the locking blocks on the housing, at which point the lower end of the housing is partially embedded in the insertion port. The conveying end of the rotating pressing cylinder 4 rotates, causing each clamping block 31 to rotate above its respective receiving groove. The output end of the rotating pressing cylinder moves downwards, pressing each clamping block into its corresponding receiving groove, thus achieving housing positioning. Then, the grinding head descends to the open end of the housing and grinds the open end face of the housing. After grinding... The grinding head is lowered to the outer wall of the housing and circumferentially ground. After the side wall of the housing is ground, the housing is moved and placed at the position corresponding to the mounting hole on the right side of the top surface of the processing table 1, with the open side of the housing facing down. Each limiting rod 5 is inserted into the hollow cavity of the housing. The translation cylinder 7 is activated, which drives each limiting rod to spread out and press against the inner side wall of the housing to limit the housing. The grinding head then grinds the unground end face of the housing. After grinding, the translation cylinder 7 is reset, and each limiting rod 5 is brought together. The stator with the ground housing removed is taken out and finally placed into the injection mold for processing again. Compared to existing technologies, this method offers several advantages. First, the supporting and clamping structures limit the outer shell by restricting the locking block. Since these structures do not obstruct the outer side of the shell, the grinding head does not need to rotate the shell during grinding. The grinding head can move around the supporting and clamping structures to separate the locking block from the shell, achieving overall shell grinding. Second, after grinding the outer side and open end of the shell, the shell can be placed within the second positioning structure of the processing table to grind the unground end face. At this point, the completely unground shell can be placed within the first positioning structure for simultaneous grinding, allowing for simultaneous grinding of the outer side, open end, and unground end face, resulting in higher grinding efficiency and work efficiency. Furthermore, the positioning of the shell by the first and second positioning structures during processing ensures better grinding accuracy.

[0027] In this invention, preferably, the top surface of the processing table 1, located at the second positioning structure, has several mounting grooves spaced circumferentially and connected to the mounting holes 200. The bottom of each mounting groove has a limiting rod 8 that can move horizontally along the radial direction of the mounting holes 200 and abut against the outer wall of the outer casing. Specifically, the mounting groove is a strip-shaped groove extending radially along the mounting holes. The mounting groove has an adjusting section and an extending section. The width of the adjusting section is greater than the width of the extending section. The extending section is located between the limiting rod 8 and the adjusting section. The bottom of the adjusting section has several adjusting holes 300 recessed into it. The rod 8 has an adjusting part 81 and a tightening part 82. The width dimension of the tightening part 82 is smaller than the width dimension of the adjusting part 81. The adjusting part 81 is embedded in the adjusting section and the length of the adjusting part 81 is shorter than the length of the adjusting section. The top surface of the adjusting part 81 has a vertically penetrating strip hole 400. The strip hole 400 is vertically aligned with each adjusting hole 300. The adjusting part 81 is locked to the bottom of the mounting groove by adjusting bolts passing through the strip hole 400 and one adjusting hole 300 in sequence. The outer end of the tightening part 82 is embedded in the protruding section and the inner end of the tightening part 82 extends into the mounting hole 200 and is tightened against the outer wall of the outer shell. In application, the limiting rod 8 is placed in the mounting groove, so that the clamping part 82 is pressed against the outer wall of the housing. The adjusting part 81 is locked in the adjusting section using the adjusting bolt, thus limiting the outer side of the housing. This, in conjunction with the limiting rod 5, provides clamping force to both the inner and outer sides of the housing, resulting in more stable housing positioning and greater precision during grinding. Furthermore, the limiting rod 8 is radially adjustable, which is beneficial for processing housings of different sizes. Also, the width of the clamping part 82 is smaller than the width of the adjusting part 81, making it less likely for the limiting rod 8 to slip out of the mounting groove.

[0028] The product form of this utility model is not limited to the illustrations and embodiments in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of this utility model.
