Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, and in particular to a riveting connection device for motor housing. Background Technology

[0002] In the field of motor manufacturing, the motor housing is a core structural component, and the reliability of the connection between its various components directly affects the motor's sealing performance, vibration resistance, and service life. Currently, the connection between motor housing components is mainly achieved through riveting, which uses rivets or stamping deformation to achieve interference or semi-interference fits. This method features high connection strength, no need for additional fasteners, and simple process. However, in existing technologies, when pressing the motor housing, a press is usually used to press the motor housing and the motor together. During the operation, a second pressing is used to flatten the bottom edge of the motor housing inward, achieving a sealed connection between the motor housing and the motor. During the pressing process, the fixture is usually manually flipped. First, the side of the fixture with the conical ring faces upward. After the first pressing, the bottom edge of the motor housing adapts to the conical ring and shrinks downward and inward. Then, the fixture is flipped over so that the side with the conical ring faces downward, and a second pressing is performed to press the bottom edge of the motor housing inward to form a flat surface. However, in this process, the fixture needs to be flipped over and its position adjusted between each two pressings, which takes up a lot of time and is inefficient. Summary of the Invention

[0022] Reference Figures 1-10This invention provides a riveting connection device for a motor housing, comprising: a fixed housing 1, a pressing mechanism 2 mounted on an upper base 101 of the fixed housing 1, a positioning seat 3 fixedly connected to a base 102 of the fixed housing 1 located directly below the pressing mechanism 2, the positioning seat 3 being used to fix the motor, a sliding plate 4 slidably mounted on the upper side of the base 102, the positioning seat 3 being located in a groove opened in the middle of the sliding plate 4, and a first cylinder 6 and a second cylinder 7 being provided on both sides of the sliding plate 4, the output ends of the two first cylinders 6 located on the same line and symmetrically arranged. The output ends of the two second cylinders 7 on both sides are located on the same line and are symmetrically arranged. The lower sides of the first cylinder 6 and the second cylinder 7 are equipped with a first mounting base 8 that can move synchronously with the sliding plate 4. The output end of the first cylinder 6 is equipped with a first pressing fixture 9, and the output end of the second cylinder 7 is equipped with a second pressing fixture 10. The first pressing fixture 9 and the second pressing fixture 10 are both slidably connected to the sliding plate 4. A guide rail mechanism 5 that drives the sliding plate 4 to move along the line connecting the first cylinder 6 and the second cylinder 7 is assembled and connected between the sliding plate 4 and the base 102. In this embodiment, the fixed housing 1 consists of an upper seat 101 and a base 102. A side plate 103 is provided on the side of the upper seat 101. The positioning seat 3 is used to fix the motor 15. The pressing mechanism 2 is located directly above the motor housing 151. The pressing mechanism 2 includes a pressing head 23. The pressing mechanism 2 controls the pressing head to descend and reset, thereby pressing the motor housing 151 and the motor 15 together. A straight groove is provided in the middle of the sliding plate 4. When the sliding plate 4 slides, the groove of the sliding plate 4 slides relative to the positioning seat 3. The first cylinder 6 and the second cylinder 7 are located on the two side edges of the sliding plate. When the first cylinder 6 and the second cylinder 7 work, their output ends extend towards the positioning seat 3. The first mounting seat 8 is slidably connected to the base 102. A linear guide rail is provided between the first pressing fixture 9 and the second pressing fixture 10 and the sliding plate 4. The linear guide rail can also be a straight groove. The first and second pressing fixtures 10 can move linearly towards the center of the sliding plate 4. When the sliding plate 4 moves, the first pressing fixtures 9 and 10 follow the sliding plate 4. The first cylinder 6 and the second cylinder 7 drive the first pressing fixtures 9 and 10 to move linearly. When the sliding plate 4 moves, the first pressing fixtures 9 and 10 drive the first cylinder 6 and the second cylinder 7 to move. At the same time, the first mounting base 8 moves simultaneously with the first cylinder 6 and the second cylinder 7. The guide rail mechanism 5 is used to drive the sliding plate 4, and simultaneously realizes the sliding plate 4 to move along the line connecting the first cylinder 6 and the second cylinder 7. The first cylinder 6 and the second cylinder 7 are located on one side of the sliding plate 4. At the same time, the moving direction of the sliding plate 4 is parallel to the side direction of the sliding plate 4 where the first cylinder 6 and the second cylinder 7 are mounted. The moving direction of the output ends of the first cylinder 6 and the second cylinder 7 is perpendicular to the moving direction of the sliding plate 4.

[0023] During the press-fitting of the motor housing, the motor housing is first placed above the positioning seat 3 to fix it in place. Then, the guide rail mechanism 5 controls the first press-fitting fixture 9 to be aligned with the positioning seat 3. The first cylinder 6 brings the first press-fitting fixture 9 closer to the motor housing. Then, the press-fitting mechanism 2 controls the press head 23 to press down, completing the first press-fitting. Then, the press head 23 of the press-fitting mechanism 2 resets, the first cylinder 6 resets, and the guide rail mechanism 5 drives the sliding plate 4 to move, so that the second press-fitting fixture 10 on the upper side of the sliding plate 4 is aligned with the positioning seat 3. Then, the second cylinder 7 brings the second press-fitting fixture 10 closer to the motor housing, and the press head 23 of the press-fitting mechanism 2 descends, performing a second press-fitting of the motor housing 151 and the motor 15. No operator needs to adjust the press-fitting tools.

[0024] Reference Figure 1 and Figure 8 The positioning base 3 includes a lower positioning block 31 fixed to the base 102. A through hole is provided in the middle of the lower positioning block 31. An upper positioning block 32 is vertically slidably connected within the through hole of the lower positioning block 31. A mounting platform 33 for positioning the motor is fixedly connected to the upper side of the upper positioning block 32. A first spring 34 is assembled and connected between the lower side of the mounting platform 33 and the lower positioning block 31. In this embodiment, the positioning base 3 is further defined. The first spring 34 reduces the pressure exerted on the motor housing by the pressing mechanism 2. Furthermore, three columns are provided on the upper part of the mounting platform 33 to fix the motor housing.

[0025] Reference Figures 2-3 The guide rail mechanism 5 includes a base plate 51 mounted between the base 102 and the sliding plate 4. A slide rail 52 is mounted and connected to the upper side of the base plate 51. The sliding plate 4 is slidably connected to the base plate 51 and the slide rail 52. A linear drive member 53 is mounted and connected to the sliding plate 4 on one side of the base plate 51. The linear drive member 53 drives the sliding plate 4 to move linearly along the slide rail 52. A soft limit mechanism 54 is mounted and connected to the other side of the base plate 51.

[0026] Reference Figure 5The linear drive component 53 includes a second mounting base 531 fixedly connected to the rear side of the base 102. A third cylinder 532 is mounted on the upper side of the second mounting base 531. A push plate 533, which is fixedly mounted to the sliding plate 4, is mounted on the output end of the third cylinder 532. In this embodiment, the sliding plate 4 is driven by the third cylinder 532. The second mounting base 531 is used to mount the third cylinder 532. The third cylinder 532 can also be directly mounted to the base 102. The base 102 is provided with an extension plate extending outward from the third cylinder 532 to fix the third cylinder 532. The base plate 51 is used to mount the slide rail 52. A soft limiting mechanism 54 prevents the sliding plate 4 from moving excessively and causing danger. When the sliding plate 4 accidentally loses control of the third cylinder 532, the soft limiting mechanism 54 can buffer the sliding plate 4 and restrict the sliding plate 4 above the base plate 51 to prevent it from sliding out.

[0027] Reference Figure 3 and Figure 7 The soft limiting mechanism 54 includes a first clamping plate 541 fixedly connected to the edge of the base plate 51. A second clamping plate 542, slidably connected to the base plate 51, is provided on the inner side of the first clamping plate 541. A second spring 543 is assembled and connected between the second clamping plate 542 and the first clamping plate 541. A limiting rod 544, which passes sequentially through the second spring 543 and the first clamping plate 541, is fixedly connected to the second clamping plate 542. In this embodiment, the soft limiting mechanism 54 is further described. The second spring 543 is provided between the first clamping plate 541 and the second clamping plate 542. When the sliding plate 4 impacts the second clamping plate, the impact force can be released through the elastic deformation of the second spring 543. The limiting rod 544 can be a screw. One end of the limiting rod 544 is fixed to the second clamping plate 542, and the other end passes through the first clamping plate 541, which can restrict the first clamping plate 541 from moving linearly.

[0028] Reference Figure 2 , Figure 5 and Figure 6 The first pressing fixture 9 includes a first fixture plate 91 slidably connected to the sliding plate 4. A first fixture shell 92 with a semi-cylindrical cavity is fixedly connected to the upper side of the first fixture plate 91. The two first fixture shells 92 are arranged symmetrically. When the two first fixture shells 92 are close together, they form a cylindrical cavity to accommodate the motor. The upper and lower parts of the two first fixture shells 92 are provided with semi-circular arc slots concentric with the central axis. The upper part of the semi-circular arc slot of the upper first fixture shell 92 is a semi-conical slot that radiates outward.

[0029] The second pressing fixture 10 includes a second fixture plate 1001 slidably connected to the sliding plate 4. A second fixture shell 1002 with a semi-cylindrical cavity is fixedly connected to the upper side of the second fixture plate 1001. The two second fixture shells 1002 are arranged symmetrically. When the two second fixture shells 1002 are close together, they form a cylindrical cavity to accommodate the motor. The upper and lower parts of the two second fixture shells 1002 are provided with semi-circular arc slots concentric with the central axis.

[0030] It should be specifically noted that the motor housing is placed on top of the motor before press fitting, with the lower edge of the motor housing located on top of the first tooling housing 92. The upper surfaces of the first tooling housing 92 and the second tooling housing 1002 are flush. During press fitting, the first tooling housing 92 is first closed, and the upper part of the motor fits tightly against the semi-circular arc slot. When the press head of the press fitting mechanism 2 presses down, the motor housing moves downward relative to the motor. Since the upper part of the semi-circular arc slot of the first tooling housing 92 is a semi-conical shape that radiates outwards, the motor housing... The groove forms a tapered contraction opening that tapers inward during the downward pressing process of the motor housing. During the second pressing, the second tooling shell 1002 closes to the motor housing. After closing, the semi-circular arc groove of the second tooling shell 1002 fits tightly against the upper part of the motor. Since the tapered contraction opening has already been formed during the first pressing, during the second pressing, under the pressure of the pressure head 23, the lower edge of the motor housing contacts the second tooling shell 1002, and the tapered contraction opening is flattened and riveted to the motor.

[0031] Reference Figure 3 The pressing mechanism 2 includes a third mounting base 21 assembled and connected to the middle of the upper seat 101. A fourth cylinder 22 is assembled and connected to the third mounting base 21, and a pressure head 23 is assembled and connected to the output end of the fourth cylinder 22. In this embodiment, the third mounting base 21 is used to install the fourth cylinder 22, and the fourth cylinder 22 controls the lifting and lowering of the pressure head 23.

[0032] Reference Figure 3 The side plate 103 is equipped with an air source treatment component 11 and a controller 12, and the front side of the base 102 is equipped with a control switch 13. In this embodiment, the controller 12 is a pneumatic programmable intelligent controller, the air source treatment component 11 is used to control the air source pressure, clean and filter the air source moisture, and provide cylinder lubrication; the control switch 13 is used to control the operation of the first cylinder 6, the second cylinder 7, the third cylinder 532, and the fourth cylinder 22.

[0033] Specific work process: Before pressing the motor housing, connect the air source and turn on the pneumatic programmable intelligent controller 12 to set the pressing pressure and pressing time for segmented pressing. The motor 15, whose housing 151 was pre-pressed manually in the previous process, is correctly placed and secured through the three columns of the positioning seat 3. Simultaneously, press the left and right start buttons on the control switch 13. The first cylinders 6 on both sides push the first pressing fixture 9 towards the center. After closing, align the motor housing pressing cover 14 with the center of the motor housing 151 and place it above the motor housing 151. Press the left and right start buttons on the control switch 13 again. The controller 12 outputs a signal, and the fourth cylinder 22 at the top pushes the pressing head 23 downwards, pressing the motor housing 151 for the first time. After pressing for 1.3 seconds, the pressing head 23 retracts and is removed. The motor housing is press-fitted with cover 14; similarly, after pressing the control switch 13 again, the first press-fitting fixture 9, which has closed, separates to both sides. The third cylinder 532 pushes the sliding plate 4 forward to the predetermined position so that the second press-fitting fixture 10 moves to the same line as the motor 15. The second cylinder 7 moves the second press-fitting fixture 10 towards the center. When it is closed and completely covers the motor housing 151, the motor housing press-fitting cover 14 is placed on the motor housing and the operation switch is pressed again; the fourth cylinder 22 at the top extends again. After pressing for 0.4 seconds, the second riveting is completed; after the two rivetings are completed, the second cylinder 7 is reset; the sliding plate 4 returns to its position under the drive of the third cylinder 532; the press-fitted motor semi-finished product is removed; then the next motor housing 151 is riveted to the motor 15, and the above process is repeated.

[0034] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
