Description

[0002] The automotive fork shaft is an important component of the automotive transmission system. With the continuous development of the automotive industry, the structure of the fork shaft has become increasingly complex in order to meet industry demands.

[0003] In current automotive fork shaft manufacturing processes, laser cutting equipment is commonly used to cut metal materials. In the metal waste generated by laser cutting, in addition to visible metal chips, some molten metal droplets splash and scatter on the worktable surface. After the molten droplets cool, they form attached solidified slag. The solidified slag cannot be recycled, resulting in a large amount of raw material loss. At the same time, if the solidified slag accumulates on the worktable surface for a long time and forms protrusions, it can easily affect the stress distribution of the equipment, leading to a decrease in processing accuracy.

[0026] Please see Figures 6-9 Two sets of symmetrical cooling mechanisms 9 are respectively set on the long side of the waste port 3. The cooling mechanism 9 includes a duct 91. The duct 91 has an air channel 911 and an arc-shaped mounting groove 912. Air outlet 1 92, air outlet 2 93 and air outlet 3 94 are evenly opened on the duct 91 in sequence. Air outlet 1 92, air outlet 2 93 and air outlet 3 94 all pass through the duct 91 and are connected to the air channel 911. Air outlet 2 93 is a straight hole with its axis perpendicular to the axis of the duct 91. Air outlet 1 92 and air outlet 3 94 are inclined holes with their axes forming an angle with the axis of the duct 91. The axes of air outlet 1 92, air outlet 2 93 and air outlet 3 94 intersect.

[0027] Inside the mounting slot 912, a switching mechanism 95 is rotatably connected via bearings. The switching mechanism 95 includes a first switching cylinder 951 and a second switching cylinder 952. Both the first switching cylinder 951 and the second switching cylinder 952 are hollow structures.

The first through hole 9511 corresponds to the first air outlet 92, and the second through hole 9521 corresponds to the third air outlet 94. The axes of the first through hole 9511 and the second through hole 9521 are perpendicular to each other, and the second air outlet 93 is in a normally open state.

[0028] A connecting rod 96 is provided between switching cylinder 1 951 and switching cylinder 2 952, and the connecting rod 96 is fixedly connected to switching cylinder 1 951 and switching cylinder 2 952 respectively.

[0029] End caps 97 are fixedly installed at both ends of the air duct 91. A motor 98 is fixedly installed on the outside of the end cap 97 near the rotating clamping mechanism 7. The output end of the motor 98 passes through the corresponding end cap 97 and is fixedly connected to the switching cylinder 951.

[0030] A pipe connector 99 is installed on the side of the air duct 91 opposite to the air outlet 93, and the pipe connector 99 is connected to the air duct 911.

[0031] The lower end of the end cover 97 is fixedly connected to a slide table 10, which is slidably connected to the upper end of the machine tool 1. Bearing seats 11 are symmetrically installed on the long sides of the waste port 3. A lead screw 12 is rotatably connected to the bearing seat 11. A motor 13 is connected to the side of the lead screw 12 near the rotary clamping mechanism 7. The lead screw 12 is threadedly connected to the slide table 10. The motor 13 is fixedly installed on the upper end of the machine tool 1. The slide table 10, bearing seats 11, lead screw 12 and motor 13 form a lead screw transmission mechanism.

[0032] A drag chain 14 is installed on the side of the screw drive mechanism away from the waste port 3. An air pipe (not shown in the figure) is installed inside the drag chain 14. The air outlet end of the air pipe is connected to the pipe joint 99, and the air inlet end of the air pipe is connected to the air source. The air source is located outside the machine tool 1.

[0033] In Example 1, when the tube is cut using the laser cutting machine 5, some metal shavings will be generated. If the metal shavings remain at the processing position, the laser will perform secondary processing on the metal shavings, which will lead to a decrease in the accuracy of the finished fork shaft or even scrap. Therefore, it is necessary to clean up the generated shavings in a timely manner.

[0034] Before laser cutting begins, motor 82 is started, which drives the arc-shaped baffle 81 to rotate. Since the material to be processed on the fork shaft is a tube, when the laser processing position deviates from the central axis of the tube, the arc-shaped baffle 81 is rotated to the side closer to the laser processing position. Airflow enters the unshielded cooling mechanism 9, avoiding the situation where the processing point directly faces the airflow, causing the debris to be blocked by the tube body and difficult to blow away. The arc-shaped baffle 81 intercepts the splashing metal debris, preventing the shielded cooling mechanism 9 from being scratched.

[0035] Start the motor 13 of the unshielded cooling mechanism 9. The motor 13 drives the lead screw 12 to rotate. The lead screw 12 drives the slide table 10 to move. The slide table 10 drives the cooling mechanism 9 to move until the axis of the air outlet 93 intersects with the axis of the laser.

[0036] Airflow is supplied to the air pipe of the unobstructed cooling mechanism 9 through an external air source. The airflow flows along the air pipe through the pipe joint 99 and enters the air duct 911. The motor 3 98 is started, and the motor 3 98 drives the switching cylinder 1 951 to rotate. The switching cylinder 1 951 drives the switching cylinder 2 952 to rotate through the connecting rod 96, so that the through hole 1 9511 and the air outlet 1 92 are staggered, and the through hole 2 9521 and the air outlet 3 94 are staggered. The air outlet 1 92 and the air outlet 3 94 are in a closed state. Since the air outlet 2 93 is in a normally open state, the airflow entering the air duct 911 is discharged through the air outlet 2 93. The air outlet 2 93 plays a guiding role, causing the airflow to blow towards the laser cutting position.

[0037] The laser cutting machine 5 is started to process the pipe. During the processing, debris is generated. Meanwhile, another set of unshielded cooling mechanisms 9 continuously delivers airflow to the laser processing position. The airflow carries the debris towards the arc-shaped baffle 81 until the debris collides with the arc-shaped baffle 81, causing the debris to fall into the guide chute 6. The debris then slides further down the guide chute 6 into the recycling box, realizing the collection of metal debris. The operator can open the machine tool 1 to remove the recycling box for easy recycling.

[0038] It should be further explained that the length of the metal tube and the position of the laser processing are known, so the positioning of the cooling mechanism 9 can be completed by motor 413.

[0039] In Example 2, in addition to visible metal fragments, there are also molten metal droplets. Based on Example 1, the molten metal droplets are dispersed by the airflow, and the dispersed molten metal droplets are cooled by the airflow to form solid slag. The solid slag and fragments collide with the arc-shaped baffle 81, causing the slag and fragments to fall into the feed trough 6, thereby achieving the collection of slag and fragments.

[0040] Based on this, when a laser processes a concave structure on the surface of a tube, if the airflow is output through the outlet hole 2 93, which is a straight hole, it may cause debris or droplets to be squeezed into the concave structure by the airflow and difficult to detach.

[0041] At this time, motor 398 is started, which drives switching cylinder 1951 and switching cylinder 2952 to rotate, so that through hole 19511 is aligned with air outlet 192 or through hole 29521 is aligned with air outlet 394, so that air outlet 192 or air outlet 394 is connected. For example, air outlet 192 is connected. Therefore, when air outlet 192 is connected and air outlet 293 is in the normally open state, airflow flows out from air outlet 192 and air outlet 293 at the same time. Since the axes of air outlet 192, air outlet 293 and air outlet 394 intersect, the airflow from different air outlets collides, causing airflow fluctuation, thereby blowing out debris or droplets from the concave structure and improving processing accuracy.

[0042] Existing technologies typically employ multiple fans to cover a large processing area, resulting in a wide dispersion of blown debris that is difficult to recycle. Furthermore, the fans are fixed to one side of the processing area, which fixes the airflow direction and fails to meet the processing requirements of the fork shaft. By using a lead screw drive mechanism to move the cooling mechanism 9, the axis of the second air outlet 93 intersects with the laser axis, effectively controlling the flight direction of debris and molten metal droplets, facilitating their recovery, and requiring only one air source device, thus effectively reducing operating costs.

[0043] In Example 3, when laser processing is performed in the same area for a long time, the amount of molten metal increases, causing a large number of molten metal droplets to be blown towards the arc-shaped baffle 81 by the airflow. During this process, due to the increase in the amount of droplets, some droplets cannot be completely cooled before impacting the arc-shaped baffle 81, thus causing the droplets to adhere to the concave surface of the arc-shaped baffle 81. As the attached droplets cool, molten slag adheres to the arc-shaped baffle 81. The long-term accumulation leads to an increase in the weight of the arc-shaped baffle 81, increasing the load on the motor 82, affecting the rotation accuracy, and reducing the protective performance of the arc-shaped baffle 81.

[0044] Therefore, when the laser cutting machine 5 stops working, the starting motor 82 drives the arc-shaped baffle 81 to rotate. During the rotation, the cutting edge of the scraper 84 is collinear with the generatrix of the concave surface of the arc-shaped baffle 81. During the rotation of the arc-shaped baffle 81, the cutting edge of the scraper 84 scrapes against the concave side of the arc-shaped baffle 81, thereby scraping off the slag adhering to the arc-shaped baffle 81.

[0045] During laser processing, motor 398 is started, which continuously drives switching cylinder 1951 and switching cylinder 2952 to rotate, thereby causing air outlet 192 and air outlet 394 to alternately conduct. When the directional air outlet 293 is conducting, air outlet 192 and air outlet 394 alternately output airflow, increasing the turbulence effect of the airflow, thereby further dispersing the droplets. The dispersed droplets are easier to cool, effectively preventing droplets from adhering to the arc-shaped baffle 81 and promoting the recycling of metal waste.
