Description

Technical Field

[0002] In the existing processing and production of automobile parts, in order to improve product quality and durability of automobile parts, grinding is a necessary processing method. Since it is the grinding treatment of the inner wall of the flow channel in the metal parts, the inner wall of the flow channel is made smooth by fine grinding of the inner wall of the flow channel, which can effectively reduce the probability of impurities adhering to the inner wall of the flow channel, which is beneficial to ensure the smooth flow of the fluid in the flow channel.

[0003] In the prior art, the grinding process of the slender flow channels inside the metal parts of automobiles is usually achieved by driving the grinding balls through a reciprocating pull rope. Since there is usually a curved structure in the flow channel, the pull rope is likely to come into contact with the curved part of the inner wall of the flow channel during the pulling process. The pull rope rubs against the inner wall of the flow channel, which can easily cause abnormal wear to the inner wall of the flow channel during the grinding process. In addition, due to the deflection of the pull rope in the flow channel, it is difficult for the grinding ball to move stably along the central axis of the flow channel, resulting in unbalanced force applied by the grinding ball, affecting the grinding effect.

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0041] Embodiment: This embodiment provides a conveniently adjustable grinding device for automobile parts processing, see Figure 1 - Fig.10Specifically, it includes a machine table 1, a fixture 102 is installed on the top of the machine table 1, two driving mechanisms 2 arranged on the outside of the fixture 102 are installed on the top of the machine table 1, and the driving mechanism 2 includes a first frame 201, a clamping member 202 is fixedly installed on the first frame 201, a pull rod 203 pointing to the clamp 102 is slidably installed in the first frame 201, and the clamping member 202 is also fixedly installed on the pull rod 203, a gear rod 204 arranged parallel to the pull rod 203 is slidably installed on the first frame 201, a servo motor 205 is fixedly installed on the first frame 201, and a fan gear 206 meshing with the gear rod 204 is fixedly installed on the driving shaft of the servo motor 205, and the meshing states of the gear rods 204 and the fan gears 206 in the two driving mechanisms 2 are oppositely arranged, when the gear rod 204 and the fan gear 206 in one driving mechanism 2 are meshed, the gear rod 204 and the fan gear 206 in the other driving mechanism 2 are not meshed. The grinding mechanism 3 is connected between the two driving mechanisms 2, and the grinding mechanism 3 includes a hose 301 firmly clamped between the clamping members 202 on the two first frames 201, and a plurality of positioning balls 302 arranged equidistantly are fixedly installed on the hose 301, and the positioning balls 302 include a first fixed cylinder 3021 fixedly sleeved on the outside of the hose 301, and a balloon 3022 is fixed around the outside of the first fixed cylinder 3021, and the outer surface of the balloon 3022 is provided with an anti- Smooth grinding pattern, the balloon 3022 is connected to the hose 301, the hose 301 is externally connected to an air pump, a plurality of positioning balls 302 are movably interspersed with a pull rope 303 arranged side by side with the hose 301, the pull rope 303 is movably interspersed in the first fixed tube 3021, a plurality of equidistantly arranged grinding balls 304 are fixedly installed on the pull rope 303, the positioning balls 302 and the grinding balls 304 are staggered, and the two ends of the pull rope 303 are firmly clamped by the clamping parts 202 on the two pull rods 203 respectively.

[0042] During the processing of automobile metal parts, some automobile metal parts are opened with long and narrow flow channels inside. These flow channels are usually used for the flow of fluids such as gas and liquid. During the production and processing, the inner wall of the flow channel is polished to make the inner wall of the flow channel smooth, and the probability of impurities adhering to the inner wall of the flow channel is reduced, which can ensure the smooth flow of the fluid in the flow channel. When using the device to polish the inner wall of the flow channel in the metal part, the staff connects the device to an external power supply so that the external power supply provides power support for the device. The staff places the automobile metal part on the clamp 102 and clamps it with the clamp 102 to ensure that the metal part is in a stable state. The staff adjusts the position of the two driving mechanisms 2 so that the two driving mechanisms 2 are respectively facing the two ports of the flow channel. Then, the staff inserts the grinding mechanism 3 of the appropriate size into the flow channel.

[0043] The grinding mechanism 3 passes through one end of the flow channel and passes through the other end of the flow channel. The staff firmly clamps the two ends of the hose 301 through the clamping members 202 fixedly installed on the first frame 201 in the two driving mechanisms 2, and firmly clamps the two ends of the pull rope 303 through the clamping members 202 on the pull rods 203 in the two driving mechanisms 2. A plurality of positioning balls 302 fixedly installed on the hose 301 and a plurality of grinding balls 304 fixedly installed on the pull rope 303 are evenly distributed in the flow channel. A grinding ball 304 is arranged between two adjacent positioning balls 302, and a grinding ball 304 is arranged between two adjacent grinding balls 303. A positioning ball 302 is arranged between the grinding balls 304. When the grinding mechanism 3 is inserted into the flow channel, the air pump connected to the hose 301 is powered on and started, and high-pressure gas is injected into the hose 301 through the air pump. Under the continuous filling of high-pressure gas, the balloon 3022 continues to expand and is finally firmly supported inside the flow channel to fix the position of the positioning ball 302. The outer surface of the balloon 3022 is provided with anti-slip wear patterns, which can effectively improve the friction resistance between the outer surface of the balloon 3022 and the inner wall of the flow channel, and to a certain extent improve the firmness and stability of the expanded support of the balloon 3022 in the flow channel.

[0044] Since the pull rope 303 is movably interspersed between the first fixed cylinders 3021 in the multiple positioning balls 302, the multiple positioning balls 302 can support the pull rope 303. When the device is started for grinding processing, the servo motors 205 in the two drive mechanisms 2 are powered on and started. After the servo motors 205 are powered on and started, the fan gear 206 fixedly connected to its drive shaft is driven to rotate. Then, with the help of the engagement between the fan gear 206 and the gear rod 204, the gear rod 204 is driven to move. During the movement of the gear rod 204, the pull rod 203 is driven to move synchronously. Under the clamping fixation of the clamping piece 202 on the pull rod 203, the pull rope 303 is pulled, driving the grinding ball 304 to move in the pull rope 303, and the pull rods 203 in the two drive mechanisms 2 will pull the pull rope 303 away. When the pull rods 203 move in the direction away from the flow channel port, the two pull rods 203 will not apply a pulling action on the pull rope 303 at the same time, and the pulling action applied by the two pull rods 203 on the pull rope 303 is performed alternately. When the gear rod 204 and the fan gear 206 in one of the driving mechanisms 2 are meshed, the gear rod 204 and the fan gear 206 in the other driving mechanism 2 are not in a meshing state. As a result, when one of the servo motors 205 drives the pull rod 203 to move away from the flow channel port, the other servo motor 205 will not apply a driving action to the corresponding pull rod 203. The pull rods 203 in the two driving mechanisms 2 alternately apply a pulling action in opposite directions to the pull rope 303, so that the numerous grinding balls 304 can reciprocate at a high frequency in the flow channel, thereby realizing the grinding process of the inner wall of the flow channel.

[0045] When the pull rope 303 is pulled back and forth, since the pull rope 303 is supported by many positioning balls 302, the pull rope 303 can be prevented from contacting the inner wall of the flow channel, so that the pull rope 303 is relatively stably located at the central axis position of the flow channel. Under the connection of the pull rope 303, the polishing ball 304 can stably and frequently reciprocate between two adjacent positioning balls 302 along the central axis of the flow channel, so as to prevent the polishing ball 304 from deflecting toward the inner wall on one side of the flow channel, resulting in uneven polishing effect, which is beneficial to ensuring the stability of the polishing processing of the inner wall of the flow channel by the multiple polishing balls 304 fixed on the pull rope 303. After the polishing of the corresponding inner wall of the flow channel within the moving range of the polishing ball 304 is completed, the position of the polishing mechanism 3 is readjusted so that the reciprocating movement trajectory of the adjusted polishing ball 304 can cover the previously unpolished position, thereby realizing comprehensive, stable and refined polishing of the inner wall of the flow channel.

[0046] In the specific implementation process, Figure 1 , Fig. 9 and Fig.10 As shown, a grille plate 101 is fixedly installed on the top of the machine 1, a clamp 102 is fixedly installed in the middle position of the top of the grille plate 101, and a collection box 103 is slidably installed in the machine 1 and is arranged directly below the grille plate 101, and the top of the collection box 103 is connected to the grille plate 101. During the use of the device, since the clamp 102 is fixedly installed in the middle position of the top of the grille plate 101, and the collection box 103 is arranged at the bottom of the grille plate 101, the metal debris generated by the grinding process above can pass through the holes in the grille plate 101 and fall into the collection box 103 below. After the processing is completed, the metal debris collected in the collection box 103 is cleaned by pulling it out, which can avoid the metal debris generated by the grinding process from accumulating on the top of the machine 1 and being difficult to clean, which is conducive to ensuring the neatness and stability of the device during long-term operation.

[0047] In the specific implementation process, Figure 6As shown, the clamping member 202 includes two symmetrically arranged slot boxes 2021, in which double-headed screws 2022 are rotatably installed, and two ends of the double-headed screws 2022 are threadedly screwed with symmetrically arranged sliders 2023, and the threads at both ends of the double-headed screws 2022 are in opposite directions. A clamping block 2024 is fixedly connected between the sliders 2023 located on the same side in the two slot boxes 2021, and a transmission belt 2025 is transmission-connected between the two double-headed screws 2022. During the use of the device, when the clamping member 202 is used to clamp and fix the hose 301 and the pull rope 303, a turning handle is fixedly installed at the end of the double-headed screw 2022. The staff places the hose 301 or the pull rope 303 between the two clamping blocks 2024 in the corresponding clamping member 202, and then turns the turning handle to drive the double-headed screw 2022 to rotate. Next, the two double-headed screws 2022 rotate synchronously. Since the threads at both ends of the double-headed screws 2022 are in opposite directions, the sliding blocks 2023 symmetrically arranged at both ends of the double-headed screws 2022 are driven to move synchronously relative to each other by virtue of the meshing of the threads during the rotation of the double-headed screws 2022, thereby causing the two symmetrically arranged clamping blocks 2024 to move synchronously relative to each other, thereby clamping the hose 301 or the pull rope 303 inserted between the two clamping blocks 2024. Since both ends of the two clamping blocks 2024 are driven to move, a closed U-shaped surrounding structure can be formed during the clamping process, which is beneficial to improving the clamping firmness of the driving mechanism 2 to the hose 301 and the pull rope 303. The clamping block 2024 has a certain thickness, which increases its contact surface with the hose 301 or the pull rope 303, and can further improve the firmness of the hose 301 and the pull rope 303 being clamped and fixed.

[0048] In the specific implementation process, Figure 7As shown, the grinding ball 304 includes a second fixed tube 3041 fixedly sleeved on the outside of the pull rope 303, and the outside of the second fixed tube 3041 is sleeved with a spherical grinding stone 3042, the outer surface of the spherical grinding stone 3042 is set to a spherical structure, the spherical grinding stone 3042 is divided into two hemispherical structures along the central axis of the second fixed tube 3041, and the hemispherical structures are inlaid with magnetically attracted magnets 3043, the hose 301 is movably inserted in the second fixed tube 3041, the outside of the pull rope 303 is integrated with an air pipe, and the outer surface of the air pipe is evenly opened with dust suction holes, the air pipe is connected to the dust suction device, and when the device is used, the outer size of the spherical grinding stone 3042 is In order to adapt to the internal dimensions of the flow channel that needs to be polished, the spherical grinding stone 3042 is arranged as two hemispherical structures inside the polishing ball 304, and with the help of the magnetic attraction of the magnet 3043 embedded in each hemispherical structure, the two hemispherical structures can form a spherical structure after being assembled, which can effectively improve the convenience of disassembly and replacement of the spherical grinding stone 3042, and facilitate replacement of the appropriate spherical grinding stone 3042 according to the internal dimensions of the flow channel during the polishing process, which can effectively improve the flexibility and applicability of the device. The two ends of the second fixed cylinder 3041 are arranged as an outwardly expanding structure, so that the spherical grinding stone 3042 is not easy to fall off from the second fixed cylinder 3041 after installation.

[0049] When the grinding ball 304 moves back and forth to grind the inner wall of the flow channel, the dust suction device connected to the air pipe on the pull rope 303 is powered on and started to suck the air in the air pipe. Since dust suction holes are evenly opened on the outer surface of the air pipe, under the suction of the air flow, the metal debris generated by the grinding enters the air pipe through the dust suction holes under the influence of the air flow, and enters the dust suction device along the air pipe, actively completing the collection and processing of the metal debris, avoiding the accumulation of metal debris in the flow channel and affecting the subsequent grinding, which is beneficial to improving the effect of the device on the grinding of the internal flow channel of metal parts. At the same time, by actively extracting the metal debris, it is beneficial to improve the convenience of collecting the metal debris after the grinding process is completed.

[0050] In the specific implementation process, Figure 5 , Fig. 9 and Fig.10As shown, a slide rail 4 surrounding the outside of the grid plate 101 is fixedly installed on the top of the machine 1, and a sliding adjustment mechanism 5 located below the driving mechanism 2 is installed on the slide rail 4. The sliding adjustment mechanism 5 includes a bearing plate 501 pointing to the clamp 102 and perpendicularly arranged at the corresponding side of the slide rail 4, and two rollers 502 clamped on the outside of the slide rail 4 are rotatably installed at the bottom of the bearing plate 501, and a bolt 503 pointing to the outer surface of the slide rail 4 is threadedly screwed on the bearing plate 501. During the use of the device, since the slide rail 4 is surrounded by the outside of the grid plate 101, the front and rear sides of the slide rail 4 are horizontally arranged, the left and right sides of the slide rail 4 are longitudinally arranged, and the adjacent sides of the slide rail 4 are arranged as an arc structure, and a device is installed below each driving mechanism 2. The sliding adjustment mechanism 5 disposed on the slide rail 4, when in use, the rollers 502 are clamped on both sides of the slide rail 4, and the position of the carrier plate 501 can be moved by sliding, and the position of the driving mechanism 2 can be adjusted, so that when the device is in use, the staff can flexibly adjust the positions of the two driving mechanisms 2 according to the positions of the flow channel ports on the metal parts, so that the device can be suitable for the flow channel grinding processing inside metal parts of different specifications. When the position adjustment of the carrier plate 501 is completed, the staff rotates the bolt 503, and drives the bolt 503 to move toward the slide rail 4 with the help of the engagement of the thread, and finally squeezes it on the outer surface of the slide rail 4 to fix the position of the carrier plate 501, so that the driving mechanism 2 can be firmly fixed after the position adjustment.

[0051] In the specific implementation process, Figure 5 As shown, a calibration mechanism 6 is connected between the driving mechanism 2 and the sliding adjustment mechanism 5, and the calibration mechanism 6 includes a second frame 601 slidably mounted on the carrier plate 501, the first frame 201 is mounted in the second frame 601, a first screw 602 arranged parallel to the carrier plate 501 is rotatably mounted, and the first screw 602 is threadedly screwed with the second frame 601, the first frame 201 is slidably mounted in the second frame 601, a second screw 603 arranged vertically is rotatably mounted at the bottom of the second frame 601, and the second screw 603 is threadedly screwed with the first frame 201. During the use of the device, the worker can adjust the position of the calibration mechanism 601 by means of the meshing of the threads. When the staff rotates the first screw 602, the position of the driving mechanism 2 on the supporting plate 501 can be adjusted. When the staff rotates the second screw 603, the position height of the driving mechanism 2 can be adjusted, which is beneficial to further improve the applicability of the device. At the same time, by adjusting the position and height of the driving mechanism 2, the clamping piece 202 on the pull rod 203 can face the port of the flow channel when clamping the pull rope 303, so that the pull rope 303 can move stably along the center position of the flow channel port when being pulled back and forth, which is beneficial to ensure the stability of the device pulling the pull rope 303 to drive the plurality of grinding balls 304 to move back and forth in the flow channel for grinding processing.

[0052] Specifically, the working principle and operation method of the present invention are as follows:

[0053] The staff firmly clamps the automobile metal parts to be polished on the fixture 102, moves the driving mechanism 2 to the appropriate position by sliding the supporting plate 501 along the slide rail 4, and firmly fixes the position of the supporting plate 501 by rotating the bolt 503. Then, the position of the driving mechanism 2 is finely adjusted by rotating the first screw 602 and the second screw 603 in the calibration mechanism 6, so that the clamping piece 202 on the pull rod 203 is aligned with the port of the flow channel. The staff inserts the polishing mechanism 3 into the flow channel and leads the two ends of the polishing mechanism 3 out from the two ends of the flow channel. The two ends of the hose 301 are firmly clamped by the clamping pieces 202 on the first frame 201 in the driving mechanism 2 outside the two ports of the flow channel. Then, the air pump is started to press the air into the balloon. 3022 is blown, and the balloon 3022 is supported in the flow channel after being inflated, so that the positions of many positioning balls 302 are firmly fixed in the flow channel. Then the staff starts the servo motor 205 to drive the fan gear 206 to rotate, and with the help of the engagement of the fan gear 206 and the gear rod 204, the pull rod 203 is driven to pull the pull rope 303 to move back and forth in the flow channel, driving the grinding ball 304 to move back and forth between two adjacent positioning balls 302 in the flow channel at a high frequency, and the inner wall of the flow channel is ground. During the grinding process, the dust suction device is powered on and started, and the metal debris generated by grinding in the flow channel is sucked and collected through the air pipe integrated on the outside of the pull rope 303. Some metal debris will also pass through the holes on the grid plate 101, fall down and be collected in the collection box 103.
