Description

Technical Field

[0001] The present invention relates to the technical field of flash removal equipment, and particularly relates to a flash removal device for the production of automotive rubber fittings. Background Art

[0002] Automotive rubber fittings are an essential and important part of automobiles, and are widely used in various systems such as engines, chassis, and bodies. Rubber fittings ensure the normal operation of each component of the automobile and the stable and reliable overall performance with their good elasticity, wear resistance, oil resistance, aging resistance, as well as excellent sealing, shock absorption, and sound insulation properties. During the molding process of rubber fittings, burrs and flash and other defects often occur at their edges. These flash not only affect the appearance quality of rubber fittings, making them look less delicate and beautiful, reducing the grade and market competitiveness of products, but also affect the assembly accuracy and sealing performance of rubber fittings. Therefore, removing the flash of automotive rubber fittings is one of the key process steps to ensure the manufacturing quality and performance of automobiles and improve the overall quality of automotive products.

[0003] Existing rubber fitting flash removal devices mainly rely on cutting tools or scraping tools to remove the flash during use. However, when the flash on the edge of rubber fittings is large and thick, simply relying on tools to remove the flash is not only time-consuming and laborious, but also difficult to ensure the flatness of flash removal, resulting in low flash removal efficiency and poor effect of the device.

[0004] Based on the above situation, the present invention proposes a flash removal device for the production of automotive rubber fittings with high flash removal efficiency. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Reference to an embodiment in this text means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0028] Embodiment 1 A burr removal device for the production of automotive rubber fittings, as Figures 1-3 shown, comprising a frame 1, a control box 11, a scraping assembly 12, a placing turntable 13, a limiting bracket 1301, a screw 1302, a motor 14, an installer 15, a storage tank 16, a pipeline 17, a limiting wheel 18 and an adjusting assembly 19. The lower part of the frame 1 is fixedly connected with the control box 11. The upper part of the front side of the frame 1 is provided with the scraping assembly 12. The middle part of the frame 1 is fixedly connected with the motor 14. The output end of the motor 14 is fixedly connected with the placing turntable 13. The middle part of the placing turntable 13 is rotatably connected with screws 1302 which are equidistantly distributed in a circle. The front side of the placing turntable 13 is slidably connected with limiting brackets 1301 which are equidistantly distributed in a circle. The limiting brackets 1301 are threadedly connected with the adjacent screws 1302. The left side of the control box 11 is fixedly connected with the installer 15. The upper and lower parts of the front side of the installer 15 are both provided with storage tanks 16. A pipeline 17 is fixedly connected and communicated between the rear sides of the upper and lower storage tanks 16. The left side of the frame 1 is provided with the adjusting assembly 19. The adjusting assembly 19 is fixedly connected with the pipeline 17. The discharging end of the pipeline 17 is fixedly connected with two limiting wheels 18, one in the front and one in the rear.

[0029] As Figures 1-3 shown, an electric valve is installed in the middle of the pipeline 17.

[0030] As Figures 1-3 shown, uniformly distributed leakage holes are formed in the middle of the limiting wheel 18.

[0031] When a worker needs to remove the flash from a circular automotive rubber fitting, the rubber fitting can be first sleeved on the three limiting brackets 1301, and then the screw rod 1302 is rotated forward to drive the three limiting brackets 1301 to move outward until the three limiting brackets 1301 are all in contact with the inner wall of the rubber fitting and limit and fix the rubber fitting. Next, the adjusting assembly 19 can be used to adjust the limiting wheels 18 and the discharge end of the pipeline 17 to appropriate positions and fix them. At this time, the two limiting wheels 18 will be in contact with the left edge of the rubber fitting, and the burrs and flash on the outer edge of the rubber fitting are located between the two limiting wheels 18. Then, the scraping assembly 12, the motor 14 and the electric valve on the pipeline 17 can be started. The scraping assembly 12 will adjust the self - carried scraper to be in contact with the outer edge of the rubber fitting, and the motor 14 will drive the placing rack 13, the limiting brackets 1301 and the rubber fitting, etc. to rotate clockwise, so that the scraper on the scraping assembly 12 can remove the burrs and flash on the outer edge of the rubber fitting. During this period, if the burrs and flash on the rubber fitting are small and thin, the storage tank 16 will spray dry - ice particles through the pipeline 17. The dry - ice particles will not only quickly cool and embrittle the burrs and flash, but also cause the burrs and flash to fall off from the rubber fitting by impact. The uniformly distributed leakage holes opened on the limiting wheels 18 are used to avoid excessive blocking of the dry - ice particles sprayed by the pipeline 17. If the burrs and flash on the rubber fitting are large and thick, the two limiting wheels 18 will leave scratches at the roots of the burrs and flash during the rotation of the rubber fitting, and the dry - ice particles sprayed by the pipeline 17 will cause more serious embrittlement of the scratched parts of the burrs and flash, so as to facilitate the subsequent complete removal of the flash by the scraper on the scraping assembly 12. After the flash removal is completed, the motor 14 and the electric valve on the pipeline 17 can be first closed, and then the limiting brackets 1301, the pipeline 17, the scraping assembly 12 and other components can be reset through components such as the screw rod 1302 and the adjusting assembly 19, and the rubber fitting can be removed.

[0032] Embodiment 2 On the basis of Embodiment 1, as Figure 1 and Figure 4 shown, it further includes a supporting mechanism. The supporting mechanism is arranged on the placing rack 13. The supporting mechanism includes an installation box frame 2, an expansion tube 21 and an air pump 22. The installation box frame 2 is fixedly connected to the left part of the placing rack 13. The expansion tube 21 is stored inside the installation box frame 2. An air pump 22 is fixedly connected to the lower part of the installation box frame 2. The air pump 22 is fixedly connected to and communicates with the expansion tube 21.

[0033] When workers need to remove the burrs of annular rubber fittings with a hollow interior and an opening on the inner side, such as a steering wheel cover, they can first pull out the expansion tube 21 from the installation box frame 2, evenly lay the expansion tube 21 inside the rubber fitting, and then start the air pump 22. The air pump 22 will inject external air into the expansion tube 21, and the expansion tube 21 will immediately expand and fill the interior of the rubber fitting. In this way, the expanded expansion tube 21 can provide additional support for the rubber fitting with a hollow interior, thus preventing the rubber fitting with a hollow interior from being easily deformed by external forces and affecting the subsequent burr removal. After the burr removal is completed, the worker can first discharge the gas inside the expansion tube 21 through the air pump 22. The expansion tube 21 will then shrink and return to its original state. Then, the shrunk expansion tube 21 can be taken out of the rubber fitting and put back into the installation box frame 2.

[0034] As Figure 1 and Figure 5 shown, it further includes an adaptation mechanism. The adaptation mechanism is arranged on the limit bracket 1301. The adaptation mechanism includes a connecting frame 3, a rotating rod 31, and a rotating bar 32. The connecting frame 3 is fixedly connected to the front end of the limit bracket 1301. A rotating bar 32 is rotatably connected to the side of the connecting frame 3 away from the limit bracket 1301. A rotating rod 31 is fixedly connected to the front side of the rotating bar 32.

[0035] When workers need to remove the burrs of small annular rubber fittings such as O-rings, they can first rotate the three rotating rods 31 and the rotating bar 32 forward by 90° and become horizontally front and back. The rotating rod 31 and the rotating bar 32 can only rotate up to 90° due to the structural limitation of the connecting frame 3. Then, the small annular rubber fitting can be put on the three rotating rods 31, and the three rotating rods 31 can be moved outward by the screw 1302 until the three rotating rods 31 are all in contact with the inner wall of the rubber fitting and limit and fix the rubber fitting. In this way, it can adapt to various small-sized annular rubber fittings and limit and fix them, facilitating the subsequent burr removal of the rubber fittings. And since the burrs and flash of the small annular rubber fittings are usually small, only the dry ice particles ejected through the pipe 17 are needed to remove the burrs. After the burr removal is completed, the worker can first remove the rubber fitting from the three rotating rods 31, and then rotate the rotating rods 31 backward by 90° to reset and re-lock them on the connecting frame 3.

[0036] As Figure 1 and Figure 6 shown, it further includes a cleaning mechanism. The cleaning mechanism is arranged on the frame 1. The cleaning mechanism includes a spraying frame 4, an air guide pipe 41, and a fan 42. The spraying frame 4 is fixedly connected to the front side of the frame 1. Fans 42 are fixedly connected to the left and right sides of the middle of the frame 1. An air guide pipe 41 is fixedly connected and communicated between the fan 42 and the spraying frame 4.

[0037] When the burrs of rubber accessories are removed, the removed burrs and flash will be separated from the rubber accessories and fall into the middle of the frame 1. At this time, the worker can start the fan 42, which will allow the outside air to enter the spray rack 4 through the air duct 41 and spray it backwards. The gas sprayed backwards will cause the fallen burrs and flash to move backwards and fall into the external collection component on the rear side of the frame 1, so that the burrs and flash that fall on the frame 1 can be cleaned in time, thereby preventing the burrs from being blown away by the wind and polluting the working environment, thereby affecting the health of the workers. After the burr removal is completed, the fan 42 can be turned off.

[0038] like Figure 7 and Figure 8 As shown, a fixing mechanism is also included, which is arranged on the limiting bracket 1301. The fixing mechanism includes a threaded sleeve 5 and a limiting bracket 51. The threaded sleeve 5 is fixed to the outside of the limiting bracket 1301, and the front side of the threaded sleeve 5 is threadedly connected to the limiting bracket 51.

[0039] Since the limit bracket 1301 is fixedly connected to the threaded sleeve 5 on the outside, when the worker puts the rubber accessory on the three limit brackets 1301, the rubber accessory is actually put on the three threaded sleeves 5. When the worker rotates the screw 1302 forward to move the three limit brackets 1301 and the threaded sleeve 5 outward and limit and fix the rubber accessory, the limit frame 51 can also be rotated forward according to the thickness of the rubber accessory, so that the limit frame 51 rotates forward and moves backward and clamps the rubber accessory in the front and back directions. In this way, it can adapt to rubber accessories of different thicknesses and clamp and fix them, thereby avoiding the front and back deviation of the rubber accessory during the rotation process and affecting the subsequent burr removal. After the burr removal is completed, the limit frame 51 can be reset while rotating in the opposite direction and moving forward.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
