Description

Technical Field

[0001] The invention relates to the technical field of steering wheel frame processing, in particular to a finishing device for processing automobile parts. Background Art

[0002] The steering wheel is a wheel-shaped device that controls the direction of travel. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft.

[0003] The current steering wheel frame is generally formed by aluminum alloy casting. After the steering wheel frame is cast, burrs are easily left at the connection between the upper and lower dies after the lower die of the die-casting mold is separated, so deburring and trimming processing is usually required. However, when deburring the annular grip plate in the steering wheel frame, it is generally necessary to use a grinding shaft to process the internal and external parts, which makes the overall processing efficiency low. At the same time, the annular cylindrical grip plate structure in the steering wheel frame will be attached with aluminum alloy debris inside and outside during the processing. The existing conventional dust removal methods such as blowing and suction can only be performed from one side, which is easy to cause debris. If the aluminum alloy debris is not cleaned thoroughly, it is easy to cause scratches on the steering wheel outer wrapping material during the subsequent foaming process of the steering wheel frame and the subsequent use of the steering wheel. In addition, during the casting process, the thin plate area between the steering wheel frame's grip structure and the steering column connecting structure below is prone to produce large casting stress during the solidification process of the casting due to uneven or too thin wall thickness, thereby causing deformation, and further resulting in non-parallelism between the steering wheel frame's grip structure and the steering column connecting structure below, making the steering wheel difficult to steer in actual use. Therefore, a finishing device for automobile parts processing is proposed. Summary of the invention

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example, see Figures 1 to 9 A finishing device for processing automobile parts, comprising a processing table 1 and a placement seat 2 for finishing a steering wheel skeleton 3, wherein a simulated steering column 4 for positioning is fixedly connected to the top of the placement seat 2, and a parallelism detection component for detecting the steering wheel skeleton 3 is connected to the outer side wall of the bottom end of the placement seat 2;

[0034] Furthermore, the top of the processing table 1 is fixedly connected to the bottom of the placement seat 2, and a plurality of limit frame plates 5 are fixedly connected to the top of the placement seat 2.

If the annular plane where the annular handle of the steering wheel skeleton 3 is located is not parallel to the annular plane where the ranging infrared sensor 7 is located (during the circular motion of the ranging infrared sensor 7, it is judged whether the measured distances of the two planes are consistent. If there is local casting stress deformation, the distance measured by the ranging infrared sensor 7 at the deformation should be greater than or less than the standard distance), it means that the upper and lower planes of the steering wheel skeleton 3 are not parallel, that is, there is casting stress deformation in the steering wheel skeleton 3.

[0036] The above advantages are as follows: in this way, the distance measuring infrared sensor 7 can be used to measure whether the plane of the annular handle of the steering wheel skeleton 3 is parallel to it by circular rotation, and unqualified products can be screened out before further processing of the steering wheel skeleton 3, thereby avoiding waste of processing resources and ensuring the qualified rate of the products;

[0037] The top of the processing table 1 is fixedly connected to an annular electric control guide rail 9 through two hydraulic push rods 8. The inner side walls of the annular electric control guide rail 9 are respectively connected to two processing sleeve rings through two guide slide seats 11. The processing sleeve rings are composed of two processing semi-rings 13. Two dressing rollers 17 for deburring the inner and outer sides of the steering wheel skeleton 3 are arranged in the two processing semi-rings 13 located in the front. The top of the dressing roller 17 is fixedly connected to a docking shaft 18. Two electromagnetic semi-rings 21 are arranged on the outer side wall of the top of the docking shaft 18. A limited axis semi-ring 26 is arranged on the inner side wall of the electromagnetic semi-ring 21. Reset components are arranged on both sides of the electromagnetic semi-ring 21.

Ring slide groove, the inner side wall of the semi-ring slide groove is fixedly connected to the outer side wall of the axis limiting semi-ring 26 through the arc-shaped slide plate 25, and the inner side wall of the axis limiting semi-ring 26 is provided with a plurality of limiting grooves adapted to the limiting front tip 19. The reset assembly is composed of a sliding column 23 and a reset spring 24. The inner side wall of the processing semi-ring 13 located at the front upper part is fixedly connected with a docking plate 20, and the docking plate 20 is provided with two docking holes larger than the diameter of the docking shaft 18. The side wall of the docking plate 20 is fixedly connected to the end of the sliding column 23 through the mounting plate, and the outer side wall of the electromagnetic semi-ring 21 is slidably connected to the outer side wall of the sliding column 23 through the sleeve plate 22. The reset spring 24 is sleeved on the outer side wall of the sliding column 23, and the two ends of the reset spring 24 are respectively fixedly connected to the two sleeve plates 22;

[0039] It should be noted that: when the steering wheel skeleton 3 is trimmed and deburred, the hydraulic push rod 8 is used to drive the annular electric control guide rail 9 to move down to the outside of the annular handle of the steering wheel skeleton 3, and then the two processed half rings 13 are controlled by the electric hinge 12 to rotate and merge on the outer wall of the annular handle of the steering wheel skeleton 3. During this process, the docking shaft 18 will be inserted into the docking hole of the docking through plate 20 and enter between the two electromagnetic half rings 21. At this time, the electromagnetic half ring 21 is in an energized state. After the two electromagnetic half rings 21 are energized, they exert magnetic repulsion on each other to separate, and the two The dressing rollers 17 are respectively located on the inner and outer sides of the annular grip of the steering wheel skeleton 3, and then the power circuits of the two electromagnetic half rings 21 are disconnected. Under the elastic force of the reset spring 24, the two sleeve plates 22 are driven to slide on the sliding column 23, and then the two electromagnetic half rings 21 are driven to move toward each other, so that the two electromagnetic half rings 21 drive the axis limiting half ring 26 to press against the outer side wall of the top of the docking shaft 18, and then the two control motors 14 below are started, and the dressing rollers 17 are driven to rotate slowly through the drive shaft 15, thereby driving the docking shaft 1 The limiting front tip 19 on the shaft limiting half ring 28 rotates slowly, and the limiting front tip 19 rotates slowly and turns into the limiting groove on the inner arc side wall of the shaft limiting half ring 26 (when the limiting front tip 19 rotates slowly, when it rotates to the limiting groove of the shaft limiting half ring 26, the limiting front tip 19 is pressed into the matching limiting groove because the shaft limiting half ring 26 has a pressing force on the docking shaft 18), so that the limiting front tip 19 and the shaft limiting half ring 26 are matched and matched, and the arc-shaped slide plate 25 is used to ensure that the docking shaft 18 is limited in rotation in the two electromagnetic half rings 21 after being pressed, so as to ensure To ensure the stability of high-speed rotation during the subsequent finishing and deburring process, after the finishing grinding roller 17 increases the speed to the deburring processing standard, the annular electric control guide rail 9 is started to control the guide slide seat 11 to slide slowly on its inner wall, and the inner and outer sides of the annular grip of the steering wheel skeleton 3 are deburred and finished. When encountering the upper and lower connection parts of the steering wheel skeleton 3, the electric hinge 12 is used to open and pass. At the same time, the grinding component 10 will extend downward to perform deburring and finishing on the lower part and other parts of the steering wheel skeleton 3. This is a prior art and will not be described in detail here.

[0040] Based on the above advantages, the two dressing rollers 17 can be controlled by the combination of the processing half ring 13 to perform deburring and dressing processing on the inner and outer sides of the annular grip of the steering wheel skeleton 3, so that the processing feed rate is constant. Compared with the existing shaft processing which requires constantly changing the processing feed rate on the annular ring, the processing difficulty is reduced, so that the overall processing efficiency is improved;

[0041] A cleaning assembly is provided in the two processing semi-rings 13 at the rear; further, the cleaning assembly is composed of an arc-shaped dust hood 27 and a receiving arc-shaped cavity plate 28, the two arc-shaped dust hoods 27 are arranged opposite to each other, the arc-shaped dust hood 27 and the receiving arc-shaped cavity plate 28 are connected to each other, the outer wall of the receiving arc-shaped cavity plate 28 is fixedly connected to the inner wall of the processing semi-ring 13 at the rear, and a high-pressure air pump for sucking processing debris is provided in the receiving arc-shaped cavity plate 28;

[0042] It should be noted that: during the processing, the electric hinge 12 will also control the two processing half rings 13 at the rear to merge, so that the two arc-shaped dust suction covers 27 are directly facing the processing parts inside and outside the annular handle of the steering wheel skeleton 3, and then the high-pressure air pump in the receiving arc-shaped cavity plate 28 is started to simultaneously realize the suction and cleaning of the processing debris on the processing parts inside and outside the annular handle of the steering wheel skeleton 3;

[0043] The above benefits are: to avoid the situation that after one side is cleaned, when cleaning the other side, the debris will run to the side of the initial cleaning when encountering the airflow, resulting in incomplete cleaning, thus ensuring efficient and comprehensive cleaning of processing debris;

[0044] When the present invention is used, the hole for docking with the steering column under the steering wheel skeleton 3 to be repaired is inserted and installed on the simulated steering column 4, and the limiting frame plate 5 is used to limit the entire steering wheel skeleton 3, which is an existing conventional limiting technical means, and then the electric control rotating ring 6 on the outer wall of the placement seat 2 is started to drive multiple ranging infrared sensors 7 to rotate. The ranging infrared sensors 7 can measure the distance between the plane where they are located and the plane where the annular handle of the steering wheel skeleton 3 is located. If the annular plane where the annular handle of the steering wheel skeleton 3 is located is not parallel to the annular plane where the ranging infrared sensors 7 are located (in the ranging During the circular motion of the infrared sensor 7, it is judged whether the distances of the two measured planes are consistent. If there is local casting stress deformation, the distance measured by the infrared sensor 7 at the deformation location should be greater or less than the standard distance), indicating that the upper and lower planes of the steering wheel skeleton 3 are not parallel, that is, there is casting stress deformation in the steering wheel skeleton 3. In this way, the infrared sensor 7 can be used to measure whether the plane where the annular handle of the steering wheel skeleton 3 is parallel to it by circular rotation, and unqualified products can be screened out before further processing of the steering wheel skeleton 3, avoiding waste of processing resources and ensuring the qualified rate of the products.

[0045] When the steering wheel skeleton 3 is trimmed and deburred, the hydraulic push rod 8 is used to drive the annular electric control guide rail 9 to move down to the outside of the annular handle of the steering wheel skeleton 3, and then the two processing half rings 13 are controlled by the electric hinge 12 to rotate and merge on the outer wall of the annular handle of the steering wheel skeleton 3. During this process, the docking shaft 18 will be inserted into the docking hole of the docking through plate 20 and enter between the two electromagnetic half rings 21. At this time, the electromagnetic half ring 21 is energized. After the two electromagnetic half rings 21 are energized, they exert magnetic repulsion on each other to separate. The two trimming grinding rollers 17 will be respectively located on the inner and outer sides of the annular handle of the steering wheel skeleton 3, and then disconnected. When the two electromagnetic half rings 21 are powered on, the two sleeve plates 22 will slide on the sliding column 23 under the elastic force of the reset spring 24, thereby driving the two electromagnetic half rings 21 to move toward each other, so that the two electromagnetic half rings 21 drive the limiting half ring 26 to press against the outer side wall of the top end of the docking shaft 18, and then start the two control motors 14 below to drive the dressing roller 17 to rotate slowly through the drive shaft 15, thereby driving the limiting front tip 19 on the docking shaft 18 to rotate slowly, and the limiting front tip 19 slowly rotates and enters the limiting groove on the inner arc side wall of the limiting half ring 26 (the limiting front tip 19 is slowly rotating). During the rotation process, when it rotates to the limiting groove of the axis limiting half ring 26, the limiting front tip 19 is pressed into the matching limiting groove because the axis limiting half ring 26 has a pressing force on the docking shaft 18), and the limiting front tip 19 and the axis limiting half ring 26 are adapted to each other, and the arc-shaped slide plate 25 is used to ensure that the docking shaft 18 is limited in rotation in the two electromagnetic half rings 21 after pressing, so as to ensure the stability of high-speed rotation in the subsequent finishing and deburring process. After the finishing grinding roller 17 increases the speed to the deburring processing standard, the annular electric control guide rail 9 is started to control the guide slide seat 11 to slide slowly on its inner wall, so as to grip the annular steering wheel frame 3. The inner and outer sides are deburred and trimmed. When encountering the upper and lower connecting parts of the steering wheel skeleton 3, the electric hinge 12 is used to open and pass through. At the same time, the grinding component 10 will extend downward to perform deburring and trimming on the lower part and other parts of the steering wheel skeleton 3. This is a prior art and will not be described in detail here. In this way, the two trimming grinding rollers 17 can be controlled by combining the processing half ring 13 to perform deburring and trimming on the inner and outer sides of the annular handle of the steering wheel skeleton 3, so that the processing feed rate is constant. Compared with the existing shaft processing that requires constantly changing the processing feed rate on the ring, the processing difficulty is reduced, and the overall processing efficiency is improved;

[0046] During the processing, the electric hinge 12 will also control the two rear processing half rings 13 to merge, so that the two arc-shaped dust hoods 27 are facing the processing parts inside and outside the annular handle of the steering wheel skeleton 3, and then the high-pressure air pump in the receiving arc-shaped cavity plate 28 is started to simultaneously realize the suction and cleaning of the processing debris on the processing parts inside and outside the annular handle of the steering wheel skeleton 3, so as to avoid the situation that after one side is cleaned, when cleaning the other side, the debris encounters the airflow and runs to the side of the initial cleaning, resulting in incomplete cleaning, thereby ensuring the efficient and comprehensive cleaning of the processing debris.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
