Description

Technical Field

[0001] This invention relates to the technical field of clutch assembly. More specifically, this invention relates to a fixing device for riveting a driven disc to a friction plate. Background Technology

[0002] In the existing technology, when riveting the clutch driven plate assembly, two friction plates need to be attached to the upper and lower sides of the driven plate respectively. Then, the two friction plates are fixed to the driven plate by a riveting machine to complete the riveting process. However, there are relatively many fixing holes on the friction plates and the driven plate, making it difficult to align the friction plates and the fixing holes on the driven plate manually. Moreover, both friction plates need to be aligned with the driven plate at the same time, which further increases the alignment difficulty. At the same time, some impurities remain on the surface of the friction plates during the production process. As a result, after the friction plates are riveted to the driven plate, some impurities will be trapped between the friction plates and the driven plate. This will cause the impurities to fall off during subsequent use, resulting in loosening and seriously affecting the performance.

[0003] The above-described background information is intended to enhance understanding of the background of this invention and should not be construed as an admission that it is prior art known to those skilled in the art. Summary of the Invention

[0018] It also achieves the goal of cleaning impurities on the lower and upper friction plates through the bellows and the impurity removal hood, avoiding the problem of poor stability caused by impurities after riveting. Furthermore, the lower friction plate, the driven disc body and the upper friction plate are separated by the first fixing block, which improves the efficiency of impurity removal.

[0038] The auxiliary unit includes a fifth telescopic cylinder 2024 and a first slider 2025; the fifth telescopic cylinder 2024 is fixedly connected to the right side of the first connecting frame 203; the telescopic end of the fifth telescopic cylinder 2024 is fixedly connected to the first slider 2025; the first slider 2025 is slidably connected to the first spline shaft 202.

[0039] The anti-deviation unit includes a third connecting frame 2026 and a limiting block 2027; the third connecting frame 2026 is bolted to the first fixing block 204 located on the front left; a limiting block 2027 is fixedly connected to the upper left and upper right parts of the third connecting frame 2026.

[0040] The drive unit includes a motor 2028, a first spur gear 2029, and a second spur gear 2030; the motor 2028 is bolted to the upper right side of the support plate 1; the output shaft of the motor 2028 is fixedly connected to the first spur gear 2029; the lower outer side of the round rod 201 is fixedly connected to the second spur gear 2030; the second spur gear 2030 meshes with the first spur gear 2029.

[0041] During preparation, the external riveting machine is manually installed behind the support plate 1. Then, the lower friction plate 4 is placed below the connecting plate 3 and simultaneously fitted onto the outside of the four positioning rods 208, ensuring the lower side of the lower friction plate 4 contacts the first fixing block 204. Next, the driven disc bushing 6 is fitted downwards onto the outside of the first splined shaft 202, and the driven disc body 5 is fitted onto the outside of the four positioning rods 208, ensuring the lower side of the driven disc body 5 contacts the lower friction plate 4, thus aligning the lower friction plate 4 and the driven disc body 5. Then, the upper friction plate 7 is fitted onto the outside of the four positioning rods 208, ensuring the lower side of the upper friction plate 7 contacts the upper side of the driven disc body 5, thus aligning the lower friction plate 4, the driven disc body 5, and the upper friction plate 7 simultaneously. Then, the second telescopic cylinder 2010 drives the second linkage block 2011 downwards, and the second linkage block 2011 drives the second splined shaft 202... 013 moves downward, the second spline shaft 2013 drives the second connecting frame 2014 to move downward, the second connecting frame 2014 drives the second fixing block 2015 to move downward, so that the second fixing block 2015 moves downward to contact the upper friction plate 7. At the same time, the six second fixing blocks 2015 and the six first fixing blocks 204 simultaneously clamp the lower friction plate 4, the driven disk body 5 and the upper friction plate 7, and the clamping positions are all staggered from the positions where the lower friction plate 4, the driven disk body 5 and the upper friction plate 7 need to be riveted. Meanwhile, the second spline shaft 2013 moves downward and is sleeved on the outside of the third linkage block 2016. In use, the lower friction plate 4, the driven disk body 5 and the upper friction plate 7 are quickly positioned and aligned by the four positioning rods 208, avoiding the problem of manually aligning the fixing holes of the lower friction plate 4, the driven disk body 5 and the upper friction plate 7, and improving the riveting efficiency.

[0042] During the alignment process, while the driven disk body 5 contacts the lower friction plate 4, the driven disk bushing 6 is supported on the upper side of the first slider 2025, thereby providing support force to the middle of the driven disk body 5 and improving the stability of the clamping and riveting process. Since the relative positions of different driven disk bushings 6 and driven disk bodies 5 in the vertical direction are different, some driven disk bodies 5 do not contact the first slider 2025 after contacting the lower friction plate 4. At this time, the fifth telescopic cylinder 2024 drives the first slider 2025 to move and adjust the height position of the first slider 2025 to adapt to the support of driven disk bushings 6 with different relative positions.

[0043] After the lower friction plate 4, driven disc body 5, and upper friction plate 7 are positioned and clamped, the third telescopic cylinder 2019 drives the third fixing block 2018 to slide to the left in the first sliding sleeve 2017, so that the third fixing block 2018 moves away from the round rod 201, stopping the fixing of the round rod 201. Then, the fourth telescopic cylinder 2022 drives the fourth fixing block 2021 to slide forward in the second sliding sleeve 2020, so that the fourth fixing block 2021 moves away from the fifth fixing block 2023, stopping the fixing of the fifth fixing block 2023, thereby stopping the fixing of the sleeve 2012. Then, the motor 2028 is started, and the motor 2028 drives the first spur gear 2029 to rotate. The first spur gear 2029 drives the second spur gear 2030 to rotate, and the second spur gear 2030 drives the round rod. Rotation of rod 201 causes the first support frame 205 to rotate, which in turn causes the parts on the support frame 205 to rotate. This causes the four positioning rods 208 to simultaneously rotate the lower friction plate 4, the driven disc body 5, and the upper friction plate 7. Simultaneously, rod 201 causes the first spline shaft 202 to rotate, which in turn causes the second spline shaft 2013 to rotate. The second spline shaft 2013 causes the stationary sleeve 2012 to rotate, which in turn causes the second connecting frame 2014 to rotate. The second connecting frame 2014 causes the second fixing block 2015 to rotate. Rod 201 also causes the first connecting frame 203 to rotate, which in turn causes the first fixing block 204 to rotate, thus causing the first fixing block 2015 to rotate. 04 and the second fixing block 2015 rotate together with the lower friction plate 4, the driven disc body 5, and the upper friction plate 7. During this process, the external riveting machine sequentially rivets the lower friction plate 4, the driven disc body 5, and the upper friction plate 7, except for the holes where the four positioning rods 208 contact. Then, the first telescopic cylinder 206 drives the first linkage block 207 to move downward. The first linkage block 207 drives the positioning rods 208 away from the lower friction plate 4, the driven disc body 5, and the upper friction plate 7. Then, the lower friction plate 4, the driven disc body 5, and the upper friction plate 7 continue to rotate through the first fixing block 204 and the second fixing block 2015. The external riveting machine rivets the remaining positions of the lower friction plate 4, the driven disc body 5, and the upper friction plate 7, thereby completing the riveting process. In use, the first... A telescopic cylinder 206 drives the positioning rod 208 away from the lower friction plate 4, the driven disc body 5, and the upper friction plate 7. Then, an external riveting machine completely rivets the lower friction plate 4, the driven disc body 5, and the upper friction plate 7 together. This eliminates the need to remove the lower friction plate 4, the driven disc body 5, and the upper friction plate 7 and perform secondary riveting on the remaining fixing blocks, thus reducing process steps and improving efficiency. At the same time, before clamping the lower friction plate 4, the driven disc body 5, and the upper friction plate 7, the third fixing block 2018 and the fourth fixing block 2021 lock the round rod 201 and the sleeve 2012 respectively, avoiding the problem of poor stability caused by the misalignment of the first fixing block 204 and the second fixing block 2015 when clamping the lower friction plate 4, the driven disc body 5, and the upper friction plate 7.At the same time, avoid interfering with the riveting process;

[0044] When the lower friction plate 4 is manually inserted onto the four positioning rods 208, the groove of the lower friction plate 4 engages with the limiting block 2027. After the positioning rods 208 move away from the lower friction plate 4, the driven disc body 5, and the upper friction plate 7, the clamping force of the first fixing block 204 and the second fixing block 2015 causes the lower friction plate 4, the driven disc body 5, and the upper friction plate 7 to rotate, which may cause misalignment. At this time, the first fixing block 204 drives the third connecting frame 2026 to perform circular motion, and the third connecting frame 2026 drives the limiting block 2027 to rotate. The positioning block 2027 performs circular motion. The limiting block 2027 drives the lower friction plate 4 to rotate through the groove. The lower friction plate 4 drives the driven disk body 5 and the upper friction plate 7 to rotate through the fixed rivets, thereby improving rotational stability. In use, the lower friction plate 4 is clamped and fixed by the limiting block 2027 to avoid the problem of misalignment of the fixing holes caused by the first fixing block 204 and the second fixing block 2015 directly driving the lower friction plate 4, the driven disk body 5 and the upper friction plate 7 to rotate through the clamping force, thereby avoiding the phenomenon of riveting failure.

[0045] Implementation Plan 2

[0046] Based on implementation plan 1, such as Figure 1-3 and Figure 9-10 As shown, the dust removal assembly includes an air box 301, a dust removal hood 302, and an expansion unit; the air box 301 is bolted between the middle of the two connecting rods 2 on the left; the dust removal hood 302 is bolted between the middle of the two connecting rods 2 on the right; and an expansion unit is connected to the upper inner side of each of the four positioning rods 208.

[0047] The expansion unit located on the front right side includes a spring telescopic rod 303, a second slider 304, a third sliding sleeve 305, a fourth linkage block 306, and an electric push rod 307. Four spring telescopic rods 303 are fixedly connected to the upper inner side of the positioning rod 208 located on the front right side. A second slider 304 is fixedly connected between the telescopic ends of every two adjacent spring telescopic rods 303. Both second sliders 304 are slidably connected to the positioning rod 208. A third sliding sleeve 305 is welded to the rear inner side of the positioning rod 208. A fourth linkage block 306 is slidably connected to the inner side of the third sliding sleeve 305. An electric push rod 307 is fixedly connected to the right inner side of the positioning rod 208, and the electric push rod 307 is located below the third sliding sleeve 305. The telescopic end of the electric push rod 307 is fixedly connected to the fourth linkage block 306. The upper surface of the fourth linkage block 306 is an inclined surface, and the contact surface between the second slider 304 and the fourth linkage block 306 is also an inclined surface.

[0048] First, connect the external air intake pipe to the input end of the bellows 301 and the external air suction pipe to the output end of the impurity removal hood 302. After the lower friction plate 4 is fitted onto the positioning rod 208 and supported on the first fixed block 204, the electric push rod 307 drives the fourth linkage block 306 to move upward. Since the contact surface between the fourth linkage block 306 and the second slider 304 is inclined, the fourth linkage block 306 pushes the second slider 304 to move and compresses the elastic telescopic rod 303, so that the lower second slider 304 passes through the positioning rod 208. Then, manually fit the driven disc body 5 onto the positioning rod 208 and support it on the lower second slider 304. Then, the fourth linkage block 306 continues to move upward, so that the upper second slider 304 passes through the positioning rod 208. Then, manually fit the upper friction plate 7 onto the positioning rod 208 and support it on the upper second slider 304. At this time, the lower friction plate 4... The driven disc body 5 and the upper friction plate 7 are spaced apart from each other. Then, the positioning rod 208 drives the lower friction plate 4, the driven disc body 5 and the upper friction plate 7 to rotate. The bellows 301 delivers airflow to the right, and the impurity removal cover 302 draws in the airflow, thereby cleaning the impurities on the lower friction plate 4 and the upper friction plate 7. This avoids the problem of poor stability caused by impurities after riveting. Then, the electric push rod 307 drives the fourth linkage block 306 to move back to its original position. The elastic telescopic rod 303 rebounds and drives the second slider 304 to move back to its original position, so that the driven disc body 5 and the upper friction plate 7 automatically slide down and fit together. In use, the bellows 301 and the impurity removal cover 302 clean the impurities on the lower friction plate 4 and the upper friction plate 7, avoiding the problem of poor stability caused by impurities after riveting. The first fixing block 204 separates the lower friction plate 4, the driven disc body 5 and the upper friction plate 7, improving the impurity removal efficiency.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application.
