Description

Technical Field

[0001] This invention relates to the technical field of motor core stacking jigs, specifically a detachable and reusable motor core stacking jig. Background Technology

[0002] During the manufacturing process of motor stator core stacking, a stacking jig is required as a positioning tool to allow the laminations to be stacked layer by layer to form the stator core.

[0003] In the existing technology, when stacking several laminations, in order to reduce the deformation of the laminations caused by inaccurate stacking, in addition to ensuring the coaxiality of the laminations, it is also necessary to align the slots on the laminations. Currently, positioning posts are often set on the stacking fixture to enable the laminations to be aligned quickly and accurately. However, the slot shapes on different types of laminations are different. Therefore, in actual use, it is necessary to design and manufacture a stacking fixture that conforms to the slot shape of the laminations, which has the disadvantages of low versatility and high cost. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a detachable and reusable motor core stacking jig.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

The lower bevel gear is sleeved and fixed to the upper part of the connecting sleeve, and the upper bevel gear is sleeved and fixed to the upper part of the shaft. Both the shaft and the connecting sleeve are rotatably connected to the support frame.

[0011] As a preferred embodiment of the present invention, the transmission assembly includes a transmission rod, one end of which is fitted with a transmission gear, and the transmission rod has a spline hole that slides with the spline portion, so that the transmission rod can drive the rotating rod to rotate.

[0012] As a preferred embodiment of the present invention, the drive unit includes a lifter and a transmission cylinder. The transmission cylinder is provided with a transmission groove, and a set of transmission teeth that can mesh with the transmission gear are provided on the inner wall of the transmission groove. The lifter is installed on the top of the middle partition plate, and the piston rod of the lifter is connected to the transmission cylinder.

[0013] As a preferred embodiment of the present invention, the transmission component includes a cylindrical support and a plurality of push plates connected to the outer wall of the cylindrical support and tangent to the cylindrical support. The end of the push plate away from the cylindrical support is bent to form a limiting baffle. An annular protrusion is provided on one side of the cylindrical support, and positioning ring grooves matching the annular protrusion are provided at both ends of the support column.

[0014] As a preferred embodiment of the present invention, the adjustment unit further includes a connecting arm connected to the movable rod, a contact head connected to the connecting arm, and a control rod rotatably connected to the base plate. The upper end of the control rod is connected to the cylindrical bracket, the lower end of the control rod protrudes from the base plate and is connected to the control device, and the contact head abuts against the push plate, so that the push plate can push the contact head to move.

[0015] As a preferred embodiment of the present invention, the supporting cylinder further includes an upper cylinder disposed at the top of the middle partition and a lower cylinder disposed at the bottom of the middle partition. The lower cylinder has a sliding through hole on its outer wall that slides with the movable rod. The upper cylinder has a reserved opening at its top that slides with the transmission cylinder.

[0016] As a preferred embodiment of the present invention, the middle partition plate and the top of the lower cylinder are both provided with mounting protrusions, and the middle partition plate and the bottom of the upper cylinder are both provided with mounting ring grooves that match the mounting protrusions.

[0017] As a preferred embodiment of the present invention, the movable support plate is provided with an L-shaped groove that provides installation space for the positioning fan and the coaxial reversing assembly, and the two ends of the connecting spring are respectively connected to the movable support plate and the lower cylinder.

[0018] The beneficial effects of this invention are:

[0019] 1. This type of detachable and reusable motor core stacking fixture uses a rotating transmission component and a connecting spring to move a movable rod and adjust the position of the movable support plate. The movable support plate maintains the coaxiality of the laminations. The positioning fan is a V-shaped positioning structure that can fit with the trapezoidal opening. When stacking laminations, the positioning fan can align the slots on the laminations. The drive unit can drive the coaxial reversing component through the transmission component to adjust the opening of the positioning fan. It can be used to position slots with different trapezoidal openings, making it more versatile and reducing the cost waste caused by designing and manufacturing different stacking fixtures.

[0020] 2. This type of detachable and reusable motor core stacking jig is suitable for use with laminations of different inner diameters because the position of the movable support plate can be adjusted. After the laminations are stacked to form the motor core, the position of the movable support plate can be adjusted to detach it from the motor core. When lifting the motor core, the movable support plate can prevent damage to the inner wall of the motor core.

[0021] 3. This type of detachable and reusable motor core stacking jig uses a lifting device to drive the transmission cylinder to rise and fall. By using transmission teeth that can mesh with the transmission gear, the transmission gear rotates, which in turn drives the transmission rod to rotate. This allows for simultaneous adjustment of the opening of multiple positioning fans, saving time.

[0022] 4. This type of detachable and reusable motor core stacking jig utilizes the splined section and splined hole to enable the rotating transmission rod to drive the rotating rod to rotate, and the transmission rod will not obstruct the movement and disassembly of the movable support plate.

[0023] 5. This type of detachable and reusable motor core stacking fixture has a movable rod and a movable support plate that are detachably connected. Therefore, by removing the movable support plate, the entire positioning unit can be removed and stored, which is beneficial for the reuse of the positioning unit. Furthermore, the versatility of the device can be further improved by replacing the positioning unit.

[0024] 6. This type of detachable and reusable motor core stacking jig, with its set mounting protrusion and mounting ring groove, can maintain the coaxiality of the lower cylinder, middle partition and upper cylinder, so that the lower cylinder, middle partition and upper cylinder can be stably and quickly assembled together, and disassembly is convenient, which is beneficial to later maintenance.

[0039] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0040] Example: Figures 1-3 As shown, the present invention discloses a detachable and reusable motor core stacking fixture, comprising a support cylinder 1 and a base plate 2 disposed at the bottom of the support cylinder 1. The support cylinder 1 includes a middle partition 14, a driving unit is disposed at the top of the middle partition 14, and an adjustment unit 7 is disposed below the middle partition 14. The adjustment unit 7 includes a movable rod 72 and a support column 77. The upper and lower ends of the support column 77 are provided with transmission components for driving the movable rod 72 to move. The base plate 2 is used to support the laminations.

[0041] The positioning unit 3 is located on the outside of the support cylinder 1. The positioning unit 3 includes a movable support plate 31, a positioning fan for aligning the slots on the punch, and a coaxial reversing assembly for adjusting the opening of the positioning fan. The movable support plate 31 is detachably connected to the movable rod 72 via a connector 32. The movable rod 72 is fitted with a connecting spring 75.

[0042] The transmission component 6 is connected to the coaxial reversing component and is driven to rotate by the drive unit.

[0043] In this embodiment, the movable rod 72 and the movable support plate 31 are detachably connected. A connection hole is provided at one end of the movable rod 72 outside the lower cylinder 12. One end of the connector 32 is connected to the movable support plate 31, and the other end is provided with a connector block that can be inserted into the connection hole. After the connector block is inserted into the connection hole, the movable rod 72 and the movable support plate 31 can be connected together using bolts and nuts. By removing the nuts, the entire positioning unit 3 can be removed and stored, which is beneficial for the reuse of the positioning unit 3. The versatility of the device can also be further improved by replacing the positioning unit 3.

[0044] It should be noted that the detachable connection between the movable rod 72 and the movable support plate 31 described above is only one embodiment, and other embodiments may also be adopted.

[0045] Among them, such as Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the positioning fan includes a positioning page 33, a positioning page 34, and a shaft 35. Positioning page 33 and positioning page 34 each have a connecting sleeve 331 and a connecting sleeve 2 on one side, allowing the shaft 35 to pass through. The upper part of the connecting sleeve 331 protrudes beyond the positioning page 33, and the shaft 35 is fixedly connected to the connecting sleeve 2. The shaft 35 and the connecting sleeve 331 are rotatably engaged. Positioning page 33 and positioning page 34 form a V-shaped positioning structure that can fit against the trapezoidal opening. During stacking of laminations, the V-shaped positioning structure allows the slots on the laminations to be aligned. Furthermore, by adjusting the angle between positioning page 33 and positioning page 34, slots with different trapezoidal openings can be positioned, resulting in higher versatility and reducing cost waste caused by designing and manufacturing different stacking jigs.

[0046] Specifically, the coaxial reversing assembly includes a support frame 36 connected to the movable support plate 31, a rotating rod 39 rotatably connected to the support frame 36, and two bevel gears 38. One end of the rotating rod 39 located outside the movable support plate 31 is provided with a spline portion 391, and the other end of the rotating rod 39 is connected to a bevel gear 37 that meshes with the first bevel gear 38. The lower bevel gear 38 is sleeved and fixed to the upper part of the connecting sleeve 331, and the upper bevel gear 38 is sleeved and fixed to the upper part of the shaft 35. Both the shaft 35 and the connecting sleeve 331 are rotatably connected to the support frame 36.

[0047] The rotating rod 39 drives the bevel gear 37 to mesh with the two bevel gears 38, so that the two bevel gears 38 rotate in opposite directions. The two bevel gears 38 drive the connecting sleeve 331 and the shaft 35 respectively, so that the connecting sleeve 331 and the shaft 35 rotate in opposite directions, thereby adjusting the angle between the positioning page 33 and the positioning page 34, and realizing the adjustment of the opening of the positioning fan.

[0048] Among them, such as Figure 3 , Figure 9 and Figure 10 As shown, the transmission assembly 6 includes a transmission rod 61, one end of which is fitted with a transmission gear 62. The transmission rod 61 has a spline hole 611 that slides with the spline portion 391, so that the transmission rod 61 can drive the rotating rod 39 to rotate. By utilizing the spline portion 391 and the spline hole 611, the rotating transmission rod 61 can drive the rotating rod 39 to rotate. The transmission rod 61 will not obstruct the movement and disassembly of the movable support plate 31.

[0049] In this embodiment, the spline hole 611 may or may not pass through the transmission rod 61, as long as it provides sufficient space for the sliding of the spline portion 391.

[0050] Among them, such as Figure 3 and Figure 9 As shown, the drive unit includes a lifter 4 and a transmission cylinder 5. The transmission cylinder 5 is provided with a transmission groove 51, and a set of transmission teeth 52 that can mesh with the transmission gear 62 are provided on the inner wall of the transmission groove 51. The lifter 4 is installed on the top of the middle partition 14, and the piston rod of the lifter 4 is connected to the transmission cylinder 5. The transmission teeth 52 are distributed radially. The lifter 4 drives the transmission cylinder 5 to rise and fall. The transmission teeth 52 that can mesh with the transmission gear 62 cause the transmission gear 62 to rotate. The transmission gear 62 drives the transmission rod 61 to rotate, so that the opening of multiple positioning fans can be adjusted at the same time, which can save time.

[0051] In this embodiment, the lifting device 4 can be electrically controlled, pneumatically controlled, or hydraulically controlled; the type of lifting device 4 is not limited here.

[0052] Among them, such as Figure 3 and Figure 9 As shown, the transmission component includes a cylindrical bracket 76 and several push plates 78 connected to the outer wall of the cylindrical bracket 76 and tangent to the cylindrical bracket 76. The end of the push plate 78 away from the cylindrical bracket 76 is bent to form a limiting baffle 79. The cylindrical bracket 76 has an annular protrusion 761 on one side, and both ends of the support column 77 are provided with positioning ring grooves 771 that match the annular protrusion 761. The annular protrusion 761 and the positioning ring grooves 771 can be used to quickly assemble the cylindrical bracket 76 and the support column 77 together; the limiting baffle 79 is used to limit the contact head 74.

[0053] Among them, such as Figure 2 , Figure 3 , Figure 11 and Figure 12As shown, the adjustment unit 7 also includes a connecting arm 73 connected to the movable rod 72, a contact head 74 connected to the connecting arm 73, and a control rod 71 rotatably connected to the base plate 2. The upper end of the control rod 71 is connected to the cylindrical bracket 76, and the lower end of the control rod 71 protrudes from the base plate 2 and is connected to the control device. The contact head 74 abuts against the push plate 78, so that the push plate 78 can push the contact head 74 to move.

[0054] The control device drives the control rod 71 to rotate, which in turn drives the support column 77. The support column 77 then drives the transmission component on it to rotate. The push plate 78 pushes the contact head 74, causing the movable rod 72 to move outward from the lower cylinder 12. At the same time, the connecting spring 75 is in a stretched state. The movable rod 72 drives the movable support plate 31 to move, and the position of the movable support plate 31 is adjusted. When the movable support plate 31 is adjusted to a suitable position, it is used to maintain the coaxiality of the laminations. After the laminations are stacked to form the motor core, the control device drives the control rod 71 to rotate in the opposite direction. The movable rod 72 moves inward from the lower cylinder 12 under the force of the connecting spring 75, allowing the movable support plate 31 to detach from the motor core. This prevents the movable support plate 31 from damaging the inner wall of the motor core when it is lifted. Since the position of the movable support plate 31 is adjustable, it is suitable for laminations with different inner diameters.

[0055] In this embodiment, the control device can be a motor or a handle, and therefore is not marked in the drawings. The control lever 71 is rotated by the motor or the rotating handle.

[0056] Among them, such as Figure 3 and Figure 9 As shown, the supporting cylinder 1 also includes an upper cylinder 11 located at the top of the middle partition 14 and a lower cylinder 12 located at the bottom of the middle partition 14. The lower cylinder 12 has a sliding through hole on its outer wall that slides with the movable rod 72. The upper cylinder 11 has a reserved opening at its top that slides with the transmission cylinder 5. The upper cylinder 11 has a through hole on its outer wall for installing the transmission rod 61. The transmission rod 61 is rotatably connected to the upper cylinder 11 through a bearing. The sliding through hole allows the movable rod 72 to move smoothly. The reserved opening allows the transmission cylinder 5 to rise and fall smoothly.

[0057] Specifically, the lower cylinder 12 is also provided with a support partition 13 to support the transmission components and support columns 77, thereby improving the stability of the transmission components and support columns 77 during rotation.

[0058] Among them, such as Figure 3 and Figure 9As shown, the top of the middle partition plate 14 and the lower cylinder 12 are both provided with mounting protrusions 16, and the bottom of the middle partition plate 14 and the upper cylinder 11 are both provided with mounting ring grooves 15 that match the mounting protrusions 16. By using the mounting protrusions 16 and mounting ring grooves 15, the coaxiality of the lower cylinder 12, the middle partition plate 14 and the upper cylinder 11 can be maintained, so that the lower cylinder 12, the middle partition plate 14 and the upper cylinder 11 can be stably and quickly assembled together, and disassembly is convenient, which is beneficial for later maintenance.

[0059] Among them, such as Figures 2-4 As shown, the movable support plate 31 has an L-shaped groove 311 that provides installation space for the positioning fan and the coaxial reversing assembly. The two ends of the connecting spring 75 are respectively connected to the movable support plate 31 and the lower cylinder 12. The L-shaped groove 311 provides space for the installation of the positioning fan and the coaxial reversing assembly, and also facilitates the adjustment of the opening degree of the positioning fan.

[0060] In this embodiment, the upper part of the movable support plate 31 is provided with a receiving hole that communicates with the L-shaped groove 311 for installing the rotating rod 39. The receiving hole needs to be large enough to allow the rotating rod 39 with the spline part 391 to pass through smoothly.

[0061] During operation, the lifting device 4 drives the transmission cylinder 5 to rise and fall. The transmission gear 52, which meshes with the transmission gear 62, causes the transmission gear 62 to rotate the transmission rod 61. The splined portion 391 and splined hole 611 enable the rotating transmission rod 61 to rotate the rotating rod 39, thus operating the coaxial reversing assembly and adjusting the opening of the positioning fan. After adjusting the opening (ensuring that positioning page 1 33 and positioning page 2 34 are in contact with the trapezoidal opening), the control device drives the control rod 71 to rotate. The control rod 71 then drives the support column 77, which in turn drives the transmission components on it. The rotating mechanism pushes the contact head 74 via the push plate 78, causing the movable rod 72 to move outward from the lower cylinder 12. Simultaneously, the connecting spring 75 is in a stretched state. The movable rod 72 drives the movable support plate 31 to move, adjusting the movable support plate 31 to a suitable position. Then, the laminations are fitted onto the movable support plate 31, which is used to maintain the coaxiality of the laminations. After the laminations are stacked to form the motor core, the control device drives the control rod 71 to rotate in the opposite direction. Driven by the elastic force of the connecting spring 75, the movable rod 72 moves inward from the lower cylinder 12, allowing the movable support plate 31 to detach from the motor core. The motor core can then be lifted using the equipment.

[0062] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
