Description

Technical Field

[0001] The present invention relates to the technical field of trimming devices, and more specifically, to a trimming device and method for machining automotive parts. Background Art

[0002] The braking system is an important part of an automobile, which mainly includes brake pads, brake discs, brake calipers, etc. The main material of the brake disc is gray cast iron. During the manufacturing process of the brake disc, due to factors such as material deformation, some burrs may be generated on the edge or surface. Before assembly, the brake disc needs to be polished to remove the burrs. Usually, a grinding machine is used for this purpose. During the grinding process of the brake disc by the grinding machine, cutting fluid is usually sprayed to cool the brake disc and the grinding head. During the grinding process, the burrs will separate from the brake disc along with the cutting fluid, so the cutting fluid will be mixed with burrs (i.e., metal chips). In order to reuse the cutting fluid, a filter screen is usually used to filter it. After the cutting fluid passes through the filter screen, it is collected, and the metal chips remain on the surface of the filter screen. After standing for a period of time, they are discharged from the filter screen. However, there is often cutting fluid remaining on the surface of the metal chips. If the cutting fluid on them is not removed as much as possible, it will cause loss of the cutting fluid.

[0003] For example, a cutting fluid circulating and filtering device disclosed in the patent with the publication number CN220296754U. Although this device is provided with a separation box for collecting the cutting fluid sprayed by the nozzle and filtering the cutting fluid under the action of a separation net to prevent waste residues and impurities from mixing in the cutting fluid and affecting the cooling effect of the cutting fluid on the workpiece, in actual use, since the separation net is fixedly inclined in the separation box, the impurities and residues in the cutting fluid will roll along the separation net and fall into the collection box, and there is still cutting fluid remaining on the surface of the impurities and residues, which will cause loss of the cutting fluid. Therefore, it needs to be improved. Summary of the Invention

The metal chips on the filter plate slide along the filter plate and fall to the bottom end of the filter plate; S4. The rotation of the rotating shaft drives the extension plate to rotate, driving the upper frame and the lower frame to continuously rise and fall, causing the metal chips in the upper frame to vibrate, thereby separating the cutting fluid from the metal chips. The metal chips remain in the upper frame, and the cutting fluid passes through the upper frame and falls into the lower frame. S5. The rotation of the rotating shaft drives the rotation of multiple rotating shafts, thereby causing the rotation of multiple impellers, promoting the gas flow in the cylinder body, the upper frame, and the lower frame, and accelerating the flow of the cutting fluid in the second connecting pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, through the arrangement of the vibrating member, the metal chips located on the filter plate can generate vibrations to promote the separation of the cutting fluid on the metal chips.

Detailed implementation manners

[0029] To further understand the content of the present invention, the present invention will be described in detail in combination with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention rather than limiting it.

[0030] The following will Figures 1-11 make a further detailed description of this embodiment.

[0031] Please refer to Figures 1-6, A trimming device for machining automotive parts in this embodiment includes a cabinet 100. There is a cavity inside the cabinet 100. An upper partition 110 and a lower partition are oppositely arranged inside the cavity. The upper partition 110 and the lower partition divide the cavity into an upper cavity, a middle cavity and a lower cavity from top to bottom. A grinding part for grinding parts is arranged in the upper cavity. The grinding part includes a movable grinding head and a spray pipe. The upper partition 110 is provided with a plurality of liquid flow holes 111 for cutting fluid to flow through. The upper partition 110 is also provided with a plurality of liquid storage pipes 300 communicating with the liquid flow holes 111. A filtering component is provided on the lower partition through a first connecting pipe 403. The filtering component includes a cylinder body 310 with an open bottom end. A filtering cavity 600 is arranged inside the cylinder body 310. A frame 610 is arranged inside the filtering cavity 600. A filter plate 611 is arranged between the frames 610. A scraping part is arranged inside the filtering cavity 600. The scraping part is used to push the metal debris on the frame 610 onto the filter plate 611; A vibrating part is also arranged inside the filtering cavity 600. The vibrating part is used to make the filter plate 611 vibrate, so that the metal debris on the filter plate 611 falls to the bottom end; A plurality of discharge grooves 810 communicating with the bottom end of the filter plate 611 are arranged on the side wall of the cylinder body 310. A liftable receiving part is arranged outside the cylinder body 310. A driving part is arranged inside the filtering cavity 600. The driving part is used to drive the receiving part to lift and lower; The receiving part includes an upper frame 410 with an open top end and a lower frame 420 arranged at its bottom end. The lifting and lowering of the receiving part is used to control the opening and closing of the discharge groove 810 so that the metal debris on the filter plate 611 falls into the receiving part. The lifting and lowering of the receiving part is also used to drive the metal debris in the upper frame 410 to vibrate, so that the cutting fluid falls into the lower frame 420; A plurality of second connecting pipes 401 communicating with the cylinder body 310 are arranged inside the lower frame 420. A suction part is also arranged inside the filtering cavity 600. The suction part is used to drive the air flow inside the filtering cavity 600 to promote the cutting fluid in the lower frame 420 to flow into the filtering cavity 600.

[0032] In this embodiment, the grinding part further includes fixed claws arranged in the upper cavity. When trimming automotive parts, first, the automotive parts are fixed by the fixed claws, and then the burrs on the automotive parts are ground by moving the grinding head. Cutting fluid is sprayed through the spray pipe to cool the grinding head and the automotive parts. The burrs break away from the automotive parts to form metal debris. The metal debris flows through the liquid flow holes 111 with the cutting fluid into the liquid storage pipes 300. There is an openable and closable valve in the liquid storage pipes 300. After finishing grinding the automotive parts, the valve in the liquid storage pipes 300 is opened. The cutting fluid and metal debris in the liquid storage pipes 300 flow into the filtering cavity 600 through the first connecting pipe 403, and then the valve in the liquid storage pipes 300 is closed; Part of the cutting fluid and metal chips fall above the filter plate 611. After the cutting fluid passes through the filter plate 611, it falls into the lower cavity from the lower opening of the cylinder body 310. The remaining part of the cutting fluid and metal chips will fall above the frame 610. Under the action of the scraping member, the cutting fluid and metal chips are made to fall above the filter plate 611. Under the action of the vibrating member, the metal chips and cutting fluid on the filter plate 611 and the frame 610 vibrate, accelerating the separation of the cutting fluid on the metal chips. Since the filter plate 611 is inclined, the metal chips on the filter plate 611 will move towards its bottom end; Under the action of the driving member, the upper frame 410 and the lower frame 420 can reciprocate up and down. When the upper frame 410 moves down to expose the discharge slot 810, the metal chips at the bottom end of the filter plate 611 can fall into the upper frame 410 through the discharge slot 810. A filter screen 500 communicating with the lower frame 420 is provided at the bottom end of the upper frame 410. During the reciprocating up and down movement of the upper frame 410 and the lower frame 420, the metal chips in the upper frame 410 can be vibrated, promoting the separation of the cutting fluid from the metal chips and passing through the filter screen 500 into the lower frame 420; Under the action of the suction member, the air in the filter chamber 600, the upper frame 410 and the lower frame 420 can flow, thereby promoting the cutting fluid in the lower frame 420 to enter the cylinder body 310 through the second connecting pipe 401 and fall into the lower cavity from the lower opening of the cylinder body 310, so that the filtered cutting fluid can be collected for subsequent use; Among them, through the setting of the vibrating member, the metal chips on the filter plate 611 can be vibrated to promote the separation of the cutting fluid on the metal chips. Compared with the existing ones, this embodiment can reduce the cutting fluid attached to the metal chips, thereby reducing the loss of cutting fluid; Among them, through the setting of the scraping member, it can push the metal chips and cutting fluid flowing to the upper part of the frame 610 to make them fall onto the filter plate 611 for filtration; Among them, through the setting of the driving member, the upper frame 410 and the lower frame 420 can reciprocate up and down, so that the metal chips at the bottom end of the filter plate 611 can fall into the upper frame 410 through the discharge slot 810, and the metal chips in the upper frame 410 can be vibrated to promote the separation of the cutting fluid from the metal chips and enter the lower frame 420; Among them, through the setting of the suction member, the air in the filter chamber 600, the upper frame 410 and the lower frame 420 can flow, thereby promoting the cutting fluid in the lower frame 420 to enter the cylinder body 310 through the second connecting pipe 401 and fall into the lower cavity from the lower opening of the cylinder body 310; Among them, a liquid storage box 130 for storing cutting fluid is provided on the cabinet body 100. The spray pipe is communicated with the liquid storage box 130. A transmission pipe 200 communicated with the liquid storage box 130 is provided in the lower cavity. A liquid extraction pump is provided in the liquid storage box 130. The liquid extraction pump can drive the filtered cutting fluid in the lower cavity into the liquid storage box 130 for subsequent use. In order to connect the cabinet body 100 to the ground, installation parts 140 are provided at both sides of the bottom end of the cabinet body 100. The installation parts 140 can be detachably connected to the ground through bolts.

[0033] Combined with Figures 3-11 As shown, in this embodiment, a rotatable rotating shaft 830 is provided in the filtering cavity 600. The scraping member includes a scraping plate 930 provided on the rotating shaft 830. One side surface of the scraping plate 930 is attached to the frame 610. The scraping plate 930 rotates to push the metal chips on the frame 610 onto the filter plate 611.

[0034] In this embodiment, a top cover is provided at the upper end of the cylinder body 310. A motor 430 for driving the rotation of the rotating shaft 830 is provided on the top cover. Starting the motor 430 drives the rotation of the rotating shaft 830. The rotation of the rotating shaft 830 can drive the rotation of the scraping plate 930. Since one side surface of the scraping plate 930 is attached to the frame 610, the metal chips gathered on the frame 610 can be pushed to move and fall onto the filter plate 611.

[0035] Combined with Figures 6-9 As shown, in this embodiment, a rotatable swing rod 710 is provided on the filter plate 611 through a second torsion spring. Opposite protrusion columns 711 are provided on the swing rod 710. The scraping plate 930 rotates and contacts the protrusion columns 711 to drive the swing rod 710 to swing, so that the swing rod 710 pushes the metal chips on the filter plate 611.

[0036] In this embodiment, a rotatable swing shaft 700 is provided in the middle of the swing rod 710. The bottom end of the swing shaft 700 penetrates through the filter plate 611. The second torsion spring is provided at the lower end of the filter plate 611. Under the torsion of the second torsion spring, without external force, the swing rod 710 can maintain a state at a fixed angle; Among them, when the scraping plate 930 rotates and contacts the protrusion columns 711, the swing rod 710 can be swung. The swing rod 710 can contact the metal chips on the filter plate 611 and move them to the bottom end of the filter plate 611 for subsequent discharge; Specifically, in order to prevent the scraping plate 930 from contacting both protrusion columns 711 on the swing rod 710 at the same time, a groove for the protrusion columns 711 to pass through is provided on the scraping plate 930. Thus, when the scraping plate 930 rotates, the scraping plate 930 will only contact one of the two protrusion columns 711, and then drive the swing rod 710 to swing.

[0037] Combined withFigures 6-9 As shown, in this embodiment, a plurality of protruding blocks 601 are oppositely arranged in the filtering cavity 600. The vibrating member includes a swinging plate 940 provided on the scraping plate 930. One end of the swinging plate 940 is provided with a rotatable knocking plate 941 through a first torsion spring. The swinging shaft 700 rotates to drive the knocking plate 941 to strike the protruding block 601, thereby causing the cylinder body 310 to vibrate.

[0038] In this embodiment, when the scraping plate 930 rotates, it can drive the swinging plate 940 to rotate. The rotation of the swinging plate 940 drives the knocking plate 941 to rotate. When the knocking plate 941 contacts the protruding block 601, it can cause the cylinder body 310 to vibrate. Since the knocking plate 941 is rotatably connected to the swinging plate 940, after the knocking plate 941 contacts the protruding block 601, the knocking plate 941 can rotate around the swinging plate 940, causing the swinging plate 940 to disengage from the protruding block 601. Under the torque action of the first torsion spring, the knocking plate 941 can reset to wait for subsequent impacts on the protruding block 601.

[0039] Combined with Figures 3-8 As shown, in this embodiment, an upper limit ring 820 and a lower limit ring 400 are oppositely arranged on the outer wall of the cylinder body 310. The upper limit ring 820 is used to limit the lifting distance of the upper frame 410, and a spring 402 for pushing the lower frame 420 to move upward is provided on the lower limit ring 400.

[0040] In this embodiment, through the setting of the lower limit ring 400, the spring 402 can be installed on the outer wall of the cylinder body 310 so that the spring 402 can push the lower frame 420 to move upward. Through the setting of the upper limit ring 820, the distance of the upper frame 410 during lifting can be limited, that is, when the top end of the upper frame 410 contacts the upper limit ring 820, the upper frame 410 cannot continue to move upward to prevent it from falling off the cylinder body 310; Specifically, the inner walls of the lower limit ring 400 and the upper limit ring 820 are provided with internal threads, and the outer side wall of the cylinder body 310 is provided with external threads that cooperate with them. The lower limit ring 400 and the upper limit ring 820 are respectively detachably installed on the outer side wall of the cylinder body 310 through threads.

[0041] Combined with Figures 3-9As shown, in this embodiment, arc-shaped grooves 800 communicating with the filter chamber 600 are oppositely provided at the outer sidewall of the cylinder body 310. An arc-shaped block 520 extending into the filter chamber 600 through the arc-shaped groove 800 is provided at the sidewall of the upper frame 410. A first horizontal groove 521 and a second horizontal groove 523 are provided at the inner wall of the arc-shaped block 520. An inclined groove 522 communicating with the first horizontal groove 521 and the second horizontal groove 523 is also provided at the inner wall of the arc-shaped block 520. The driving member includes an extension plate 920 provided on the rotating shaft 830. The extension plate 920 can slide in the first horizontal groove 521, the second horizontal groove 523, and the inclined groove 522. The extension plate 920 sliding in the first horizontal groove 521, the second horizontal groove 523, and the inclined groove 522 is used to drive the arc-shaped block 520 to move up and down.

[0042] In this embodiment, the first horizontal groove 521 and the second horizontal groove 523 are not at the same height. The inclined groove 522 communicates with the two. When the extension plate 920 rotates from the first horizontal groove 521 along the inclined groove 522 into the second horizontal groove 523, due to a certain height difference between the first horizontal groove 521 and the second horizontal groove 523, the extension plate 920 will squeeze the arc-shaped block 520 to move it downward, thereby driving the upper frame 410 and the lower frame 420 to move downward. At this time, the discharge groove 810 is exposed, and the metal debris at the bottom end of the filter plate 611 can fall into the upper frame 410 through the discharge groove 810. The spring 402 is squeezed by the downward-moving lower frame 420. When the extension plate 920 continues to rotate and disengages from the second horizontal groove 523, under the elastic force of the spring 402, the upper frame 410 and the lower frame 420 will move upward, thereby causing the metal debris in the upper frame 410 to vibrate, promoting the cutting fluid to shed the metal debris and fall into the lower frame 420; Among them, there is a certain distance between the oppositely arranged arc-shaped blocks 520. When the rotating shaft 830 stops rotating, the extension plate 920 will not be located on any arc-shaped block 520. Thus, the upper frame 410 can be located at the bottom end of the upper limit ring 820. At this time, the sidewall of the upper frame 410 can block the discharge groove 810. In order to control the position where the extension plate 920 stops, the motor 430 uses a servo motor; Specifically, when the extension plate 920 stops at the gap between the arc-shaped blocks 520, under the elastic force of the spring 402, the upper frame 410 will move upward to the bottom end of the upper limit ring 820. At this time, the extension plate 920 is at the same height as the first horizontal groove 521, so that the extension plate 920 can extend into the first horizontal groove 521 when it rotates; Among them, when the spring 402 pushes the upper frame 410 to move upward and is at the top, the arc-shaped block 520 abuts against the top of the arc-shaped groove 800 (i.e., the lower end of the filter plate 611). Thus, when the upper frame 410 moves downward, the blockage of the discharge groove 810 can be released, so that the metal debris at the bottom end of the filter screen 500 can be discharged into the upper frame 410 through the discharge groove 810.

[0043] Combined with Figures 3-8 As shown in the figure, in this embodiment, the upper frame 410 includes a first semi-circular frame. One side of the first semi-circular frame is hinged with a second semi-circular frame, and a bolt for connecting the second semi-circular frame is provided on the other side of the first semi-circular frame.

[0044] In this embodiment, one side of the first semi-circular frame is hinged to the second semi-circular frame, forming a structure similar to a clamp between them. When it is necessary to fix the upper frame 410 to the outer wall of the cylinder body 310, the first semi-circular frame and the second semi-circular frame can be moved to a position parallel to the arc-shaped groove 800, and then the first semi-circular frame and the second semi-circular frame are rotated to make them approach each other, so that the arc-shaped block 520 on the first semi-circular frame passes through an arc-shaped groove 800, and the arc-shaped block 520 on the second semi-circular frame passes through another arc-shaped groove 800, and they are fixed by bolts. When it is necessary to remove the upper frame 410 from the outer wall of the cylinder body 310, the fixation between them can be released by bolts, and then the second semi-circular frame is rotated to move it away from the first semi-circular frame, so that the arc-shaped block 520 is disengaged from the arc-shaped groove 800, so that the upper frame 410 can be detached from the outer wall of the cylinder body 310, and the metal debris located in the first semi-circular frame and the second semi-circular frame can be taken out; Among them, the lower partition board includes a placement board 120 located inside the cabinet body 100 and a plug-in board 121 for installing the cylinder body 310. The plug-in board 121 is detachably installed on the placement board 120 by countersunk head screws. The two ends of the first communication pipe 403 are respectively detachably connected to the liquid storage pipe 300 and the cylinder body 310 through joints, and the two ends of the second communication pipe 401 are also respectively detachably connected to the cylinder body 310 and the lower frame 420 through joints. Before removing the plug-in board 121 from the placement board 120, the connection between the first communication pipe 403 and the cylinder body 310 can be released. Before removing the upper frame 410 from the cylinder body 310, the connection between the second communication pipe 401 and the cylinder body 310 can be released.

[0045] Combined with Figures 3-11 As shown in the figure, in this embodiment, a first sealing plate 531 is provided on the first semi-circular frame. The first sealing plate 531 is lifted and lowered to cooperate with the upper limit ring 820 to close the upper end opening of the first semi-circular frame.

[0046] In this embodiment, through the setting of the first sealing plate 531, the upper end opening of the first semi-circular frame can be closed, so as to prevent the metal debris in the first semi-circular frame from escaping from its upper end opening during the continuous lifting and lowering of the upper frame 410; Among them, the first sealing plate 531 and the first semi-circular frame are detachably connected by screws. After the upper frame 410 is installed on the cylinder body 310, the first sealing plate 531 can be installed at the upper side opening of the first semi-circular frame; Specifically, the first sealing plate 531 is slightly smaller than the first semi-circular frame. When the first sealing plate 531 moves downward, it can contact the upper limit ring 820. At this time, the amount of gas in the upper frame 410 and the lower frame 420 is constant. Under the action of the suction member, the gas in the upper frame 410 can flow through the discharge groove 810 into the filtration chamber 600, and the gas in the lower frame 420 will enter the cylinder body 310 through the second connecting pipe 401, creating a negative pressure in the upper frame 410 and the lower frame 420, thereby promoting the flow of the cutting fluid in the lower frame 420. When the first sealing plate 531 moves upward and detaches from the upper limit ring 820, the outside air can supplement into the first semi-circular frame.

[0047] As shown in Figures 3-9 In this embodiment, a fixed ring frame 840 is provided in the cylinder body 310. A plurality of rotatable rotating shafts are provided in the fixed ring frame 840. The suction member includes an impeller 911 provided on the rotating shaft. The rotation of the impeller 911 is used to drive the gas flow in the filtration chamber 600, the upper frame 410, and the lower frame 420. A synchronizing member for driving the rotation of the plurality of rotating shafts is also provided in the cylinder body 310.

[0048] In this embodiment, when the rotating shaft rotates, it can drive the impeller 911 located thereon to rotate, thereby making the air in the filtration chamber 600, the upper frame 410, and the lower frame 420 flow, promoting the cutting fluid in the lower frame 420 to enter the cylinder body 310 through the second connecting pipe 401 and fall into the lower cavity from the lower end opening of the cylinder body 310; Specifically, the rotating shaft is rotatably installed on the fixed ring frame 840 through bearings; Among them, through the setting of the synchronizing member, when the rotating shaft 830 rotates, it can drive the plurality of rotating shafts to rotate accordingly, without the need for multiple power sources.

[0049] As shown in Figures 3-9 In this embodiment, the synchronizing member includes a first gear 900 provided on the rotating shaft 830. A second gear 910 meshing with the first gear 900 is provided on the rotating shaft. The rotation of the first gear 900 is used to drive the rotation of the plurality of second gears 910.

[0050] In this embodiment, the tooth number ratio of the first gear 900 to the second gear 910 is 10:1. Thus, when the first gear 900 rotates one circle, the second gear 910 can rotate ten circles, thereby accelerating the rotation speed of the impeller 911. Moreover, four impellers 911 are provided. Thus, the pressure generated when the impellers 911 rotate can be increased, thereby accelerating the rate at which the cutting fluid enters the cylinder body 310 through the second connecting pipe 401.

[0051] The present invention also provides a usage method of the above-mentioned trimming device for automobile part processing, including the following specific steps: S1. Fix the automotive part in the upper cavity, move the grinding head to grind the burrs on the automotive part, and the spray pipe sprays cutting fluid to cool down the automotive part and the grinding head. While the cutting fluid is flowing, it drives the metal chips to fall off the automotive part. The cutting fluid and the metal chips fall onto the upper partition plate 110 and gather into the liquid storage pipe 300 along the liquid flow holes 111; S2. Open the valve in the liquid storage pipe 300. The metal chips and the cutting fluid in the liquid storage pipe 300 enter the cylinder body 310 through the first connecting pipe 403 and fall onto the frame 610 and the filter plate 611. The cutting fluid passes through the filter plate 611 and falls into the lower cavity, and then close the valve in the liquid storage pipe 300; S3. Start the motor 430 to drive the rotating shaft 830 to rotate, so that the scraping plate 930 rotates. The scraping plate 930 pushes the metal chips gathered on the frame 610 onto the filter plate 611. While the scraping plate 930 is rotating, it drives the swing shaft 700 and the knocking plate 941 to rotate. The knocking plate 941 impacts the raised block 601 to make the cylinder body 310 vibrate. The metal chips on the filter plate 611 slide along the filter plate 611 and fall to the bottom end of the filter plate 611; S4. The rotating shaft 830 rotates to drive the extension plate 920 to rotate. When the extension plate 920 passes through the inclined groove 522 from the first horizontal groove 521 and rotates into the second horizontal groove 523, the arc-shaped block 520 drives the upper frame 410 and the lower frame 420 to move downward. The downward movement of the upper frame 410 exposes the discharge groove 810. The metal chips at the bottom end of the filter plate 611 can fall into the upper frame 410 through the discharge groove 810. The extension plate 920 continues to rotate. When the extension plate 920 falls off the second horizontal groove 523, under the elastic force of the spring 402, the upper frame 410 and the lower frame 420 move upward. Repeat this process continuously to make the metal chips in the upper frame 410 vibrate, promoting the separation of the cutting fluid from the metal chips. The metal chips remain in the upper frame 410, and the cutting fluid passes through the upper frame 410 and falls into the lower frame 420; S5. The rotating shaft 830 rotates to drive the first gear 900 to rotate. The first gear 900 rotates to drive the second gear 910 to rotate, and then drives a plurality of rotating shafts to rotate, and finally makes a plurality of impellers 911 rotate, promoting the gas flow in the filter chamber 600, the upper frame 410 and the lower frame 420, and accelerating the flow of the cutting fluid in the second connecting pipe 401.

[0052] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
