Description

Technical Field

[0001] This application relates to the field of motor processing technology, and in particular to motor disassembly fixtures. Background Technology

[0002] As a core power device in the industrial field, the connection structure between the motor housing and the end cover typically uses a rolled edge of the housing to securely connect with the connecting groove of the end cover to ensure sealing and mechanical strength. During motor repair, testing, or component replacement, it is necessary to separate the motor housing from the end cover to inspect the internal components.

[0003] Currently, when it is necessary to disassemble the housing and end cap of such motors, a combination of manual operation and general-purpose tools is commonly used. Operators typically use flathead screwdrivers, pry bars, or other sharp hand tools to attempt to insert them into the connecting groove formed by the edges of the housing and end cap. By repeatedly prying and applying leverage, the rolled edge structure is gradually pried open or deformed and enlarged, ultimately achieving separation of the housing and end cap.

[0004] Regarding the aforementioned technologies, the inventors believe that when operators apply excessive prying force to the connecting groove of the motor housing and end cover using sharp tools, there is a risk of slippage injuring the operator or damaging the workbench. Improper use of force may lead to operator hand fatigue or injury. Utility Model Content

[0005] The purpose of this application is to provide a motor disassembly fixture to improve the risk of slippage and injury to the operator or damage to the workbench when the operator applies excessive prying force to the connecting groove of the motor housing and end cover using sharp tools, and the problem that improper force may cause operator hand fatigue or injury.

[0006] The motor disassembly fixture provided in this application adopts the following technical solution: The motor disassembly fixture includes a base with a mounting seat for placing the motor. Above the base is a pressure seat corresponding to the motor. A retaining plate corresponding to the connection groove between the motor housing and the end cover is rotatably mounted in the pressure seat. The end of the retaining plate has a tip that fits into the connection groove of the motor housing. The top of the pressure seat has a movable seat that moves the pressure seat downwards. Below the movable seat is a push plate that pushes the retaining plate to rotate. When the retaining plate rotates, the tip pries open the portion of the housing that is engaged in the connection groove of the end cover, thus separating the end cover from the housing.

[0007] By adopting the above technical solution, the tip of the clamping plate can fit into the connection slot of the motor housing. The moving seat at the top of the pressure seat can drive the pressure seat to move down during the downward pressing process driven by the driving cylinder. The push plate below the moving seat pushes the clamping plate to rotate during the downward movement of the pressure seat. This allows the tip to pry open the part of the housing that is clamped into the end cover connection slot when the clamping plate rotates, thereby separating the end cover from the housing. Through the prying action of the tip, the disassembly of the motor end cover and housing can be completed efficiently and stably, improving disassembly efficiency and reducing the difficulty and risks of manual operation.

[0008] Optionally, the base is provided with a column that is slidably connected to the movable seat. The outer wall of the column is provided with an elastic element that abuts against the movable seat and the base. The mounting seat has a mounting groove that fits against the end of the motor. The mounting groove has a positioning protrusion that corresponds to the hole at the end of the motor housing. The mounting seat has support rods on both sides that correspond to the pressure seat. The top of the support rod is threaded with a long-shank bolt. When the pressure seat moves down, it abuts against the top of the long-shank bolt. The top of the long-shank bolt corresponds to the top of the motor on the mounting seat.

[0009] By adopting the above technical solution, the elastic element 1 on the outer wall of the column abuts against the movable seat and the base. During the downward movement of the movable seat, the elastic element 1 is compressed. After disassembly, the elastic force of the elastic element 1 can assist the movable seat and the pressure seat in resetting, saving the manpower and time required for resetting. The positioning protrusion in the mounting groove corresponds to the hole at the end of the motor housing, which can accurately position the motor and ensure that the motor is in the correct position on the mounting seat. The long shank bolt on the support rod limits the downward movement of the pressure seat and prevents the pressure seat from moving too far downward and damaging the motor.

[0010] Optionally, the pressure seat has a positioning groove corresponding to the end cover of the motor, and the inner side wall of the positioning groove has a fixing groove corresponding to the card plate. The card plate is rotatably connected to the inner side wall of the fixing groove. The push plate is inserted into the fixing groove and abuts against the card plate. The pressure seat has a positioning rod facing the moving seat. The bottom of the moving seat has a sliding hole corresponding to the positioning rod, and the positioning rod is slidably connected to the sliding hole.

[0011] By adopting the above technical solution, the positioning groove through the pressure seat corresponds to the end cover of the motor, ensuring that the end cover remains stable during disassembly and facilitating the accurate application of the clamping plate and the tip to the connecting groove position. The clamping plate is rotatably connected to the inner wall of the fixed groove, providing a support point for the clamping plate to rotate, allowing the clamping plate to rotate flexibly within the fixed groove and accurately engage with the connecting groove of the motor housing. When the moving seat moves down, the pushing plate moves down with the moving seat and abuts against the clamping plate. The pressure seat abuts against the long shank bolt, and the pushing plate continues to move down, pushing the clamping plate to rotate, thereby enabling the tip to pry the connecting groove part of the housing.

[0012] Optionally, a limiting hole is provided on the inner wall of the sliding hole, and a limiting block is provided on the top of the positioning rod to fit against the inner wall of the limiting hole.

[0013] By adopting the above technical solution, the limiting hole opened on the inner side wall of the sliding hole fits with the limiting block extended from the top of the positioning rod. The limiting block slides in the limiting hole, which can prevent the positioning rod from disengaging from the sliding hole, ensuring that the positioning rod and the sliding hole always remain connected, and preventing the pressure seat and the moving seat from separating and falling.

[0014] Optionally, the bottom of the movable seat is provided with a positioning post that is inserted into the positioning groove. The positioning post has a clearance groove that corresponds to the card plates on both sides. Several positioning rods and sliding holes are arranged around the positioning post.

[0015] By adopting the above technical solution, the positioning column can further position the pressure seat, ensuring that the position of the pressure seat and the motor end cover are accurately aligned. At the same time, the positioning groove provides sufficient space for the rotation of the clamping plate, avoiding interference from the positioning column on the rotation of the clamping plate, so that the clamping plate can rotate smoothly in the fixed groove, and realize the prying of the connection groove between the top and the end cover.

[0016] Optionally, the outer side of the positioning rod is provided with an elastic element two that abuts against the pressure seat and the moving seat.

[0017] By adopting the above technical solution, the elastic element 2 set on the outside of the positioning rod abuts against the pressure seat and the moving seat. When the moving seat drives the pressure seat to move down, the pressure seat abuts against the long shank bolt, and the elastic element 2 is compressed. After disassembly, the elastic element 2 pushes the pressure seat and the moving seat to reset, realizing the automatic reset function of the pressure seat, reducing manual operation steps and improving work efficiency.

[0018] Optionally, the pressure seat is provided with a fixing post outside the fixing groove, and the fixing post is connected to an elastic element three that passes through the fixing groove and is connected to the card plate.

[0019] By adopting the above technical solution, after the push plate pushes the card plate to rotate and completes the disassembly action, when the moving seat moves upward with the drive end of the drive cylinder, the elastic force of the elastic element three causes the card plate to automatically reset and return to the initial position, which facilitates the next disassembly operation.

[0020] Optionally, the end of the push plate near the card plate is inclined, and the side of the card plate away from the positioning groove has an inclined surface corresponding to the inclined surface of the push plate.

[0021] By adopting the above technical solution, when the inclined surface of the push plate contacts the inclined surface of the clamping plate, the guiding effect of the inclined surface transforms the linear motion of the push plate into the rotational motion of the clamping plate, reducing the frictional resistance during the pushing process, making the rotation of the clamping plate more flexible, improving the smoothness and efficiency of the disassembly operation, and at the same time, avoiding the clamping plate from jamming or being damaged due to uneven force, thus improving the reliability and stability of the tooling.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The tip of the card plate can fit into the connection slot of the motor housing. The moving seat on the top of the pressure seat can move the pressure seat downward during the driving cylinder. The push plate below the moving seat pushes the card plate to rotate during the downward movement of the pressure seat, so that the tip prys open the part of the housing that is stuck in the end cover connection slot when the card plate rotates, thereby separating the end cover from the housing. 2. After the push plate rotates the card plate to complete the disassembly action, when the moving seat moves upward with the drive end of the drive cylinder, the elastic force of the elastic element three causes the card plate to automatically reset and return to the initial position, which facilitates the next disassembly operation. 3. When the inclined surface of the push plate contacts the inclined surface of the clamping plate, the guiding effect of the inclined surface converts the linear motion of the push plate into the rotational motion of the clamping plate, reducing the frictional resistance during the pushing process, making the rotation of the clamping plate more flexible, and improving the smoothness and efficiency of the disassembly operation.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4This application will be described in further detail below.

[0026] Motor disassembly tooling, refer to Figure 1 and Figure 2 The system includes a base 1, on which a mounting seat 11 for placing a motor 2 is bolted. A pressure seat 3 corresponding to the motor 2 is located above the base 1. A movable seat 4, which moves downwards along with the pressure seat 3, is located on top of the pressure seat 3. A column 12 is bolted to the base 1, and the column 12 passes through the movable seat 4 and is slidably connected to a sliding hole on the movable seat 4. An elastic element 121, which is a spring, is installed on the outer wall of the column 12 and abuts against the movable seat 4 and the base 1. The elastic element is driven by a drive cylinder (not shown in the figure) mounted on a bracket (not shown) on one side of the base 1. The drive end (not shown) drives the moving seat 4 to move toward the pressure seat 3; the pressure seat 3 is rotatably provided with a clamping plate 31 corresponding to the position of the connecting groove 23 between the housing 21 of the motor 2 and the end cover 22. The end of the clamping plate 31 is provided with an integrally formed tip 311. The tip 311 fits into the position of the connecting groove 23 of the housing 21 of the motor 2. A push plate 41 is inserted below the moving seat 4 to push the clamping plate 31 to rotate. When the clamping plate 31 rotates, the tip 311 pries open the part of the housing 21 that is stuck in the connecting groove 23 of the end cover 22, so that the end cover 22 is separated from the housing 21.

[0027] Reference Figure 1 and Figure 4 The mounting base 11 has a mounting groove 111 that fits with the end of the motor 2. A positioning protrusion 112 corresponding to the hole at the end of the outer casing 21 of the motor 2 is inserted into the mounting groove 111. The positioning protrusion 112 is inserted into the hole at the outer end of the motor 2 to fix the position of the motor 2. Support rods 13 corresponding to the pressure seat 3 are fixed to the base 1 on both sides of the mounting base 11 with bolts. A long shank bolt 131 is threaded to the top of the support rod 13. When the pressure seat 3 moves down, it abuts against the top of the long shank bolt 131, which facilitates the push plate 41 to push the clamping plate 31 to rotate. The top of the long shank bolt 131 corresponds to the top of the motor 2 on the mounting base 11.

[0028] Reference Figure 2 and Figure 3A positioning groove 32 corresponding to the end cover 22 of the motor 2 is provided through the pressure seat 3. A fixing groove 33 corresponding to the clamping plate 31 is opened on the inner side wall of the positioning groove 32. The clamping plate 31 and the inner side wall of the fixing groove 33 are rotatably connected by a rotating shaft. The pushing plate 41 is inserted into the fixing groove 33 and abuts against the clamping plate 31. A positioning rod 34 is threadedly connected to the pressure seat 3 facing the moving seat 4. A sliding hole 42 corresponding to the positioning rod 34 is opened at the bottom of the moving seat 4. The positioning rod 34 is slidably connected to the sliding hole 42. A limit hole 43 is opened on the inner side wall of the sliding hole 42. A limit block 341 that fits against the inner side wall of the limit hole 43 is integrally formed on the top of the positioning rod 34 to prevent the pressure seat 3 from disengaging from the moving seat 4. The movable seat 4 has a positioning post 44 welded to its bottom, which is inserted into the positioning groove 32. The positioning post 44 has a clearance groove 441 corresponding to the clamping plates 31 on both sides. The positioning rod 34 and the sliding hole 42 are arranged around the positioning post 44. An elastic element 35 is arranged on the outside of the positioning rod 34 to abut against the pressure seat 3 and the movable seat 4. The elastic element 35 is a spring. When the movable seat 4 moves down, the pressure seat 3 abuts against the long shank bolt 131, and the elastic element 35 is compressed. At the same time, the push plate 41 moves down and pushes the clamping plate 31 to rotate, prying open the connection position of the connecting groove 23 between the outer shell 21 of the motor 2 and the end cover 22. After disassembly, the elastic element 35 pushes the pressure seat 3 and the movable seat 4 to reset.

[0029] Reference Figure 2 and Figure 3 The pressure seat 3 is located outside the fixed groove 33 and is threadedly connected to the fixed post 36. An elastic element 37, which passes through the fixed groove 33 and is connected to the clamping plate 31, is connected to the fixed post 36. The elastic element 37 is a spring. After the push plate 41 pushes the clamping plate 31 to rotate and complete the disassembly action, when the moving seat 4 moves upward with the drive end of the drive cylinder, the elastic element 37 pulls the clamping plate 31 back to its original position. The end of the push plate 41 near the clamping plate 31 is set with an inclined surface. The side of the clamping plate 31 away from the positioning groove 32 is provided with an inclined surface 312 corresponding to the inclined surface of the push plate 41. When the inclined surface of the push plate 41 contacts the inclined surface 312 of the clamping plate 31, the guiding effect of the inclined surface converts the linear motion of the push plate 41 into the rotational motion of the clamping plate 31, reduces the frictional resistance during the pushing process, makes the rotation of the clamping plate 31 more flexible, and improves the smoothness and efficiency of the disassembly operation.

[0030] The implementation principle of this application embodiment is as follows: After fixing the motor 2 onto the mounting base 11, the drive section of the drive cylinder pushes the moving base 4, which in turn moves the pressure base 3 downwards, causing the pressure base 3 to abut against the long-handled bolt 131. The positioning groove 32 of the pressure base 3 corresponds to the position of the end cover 22 of the motor 2. The tip 311 of the clamping plate 31 engages with the connection position of the connecting groove 23 between the outer shell 21 of the motor 2 and the end cover 22. As the moving base continues to move downwards, the push plate pushes the clamping plate 31 to rotate, causing the tip 311 to pry open the connection position of the connecting groove 23 between the outer shell 21 of the motor 2 and the end cover 22. This achieves the separation of the end cover 22 from the outer shell 21. Through the prying action of the tip 311 of the clamping plate 31, the disassembly of the end cover 22 and the outer shell 21 of the motor 2 can be completed efficiently and stably, improving disassembly efficiency and reducing the difficulty and risks of manual operation.
