Description

Technical Field

[0001] The invention relates to the technical field of automobile component manufacturing, in particular to an automobile component aluminum profile surface finishing device and a finishing process. Background Art

[0002] Aluminum profiles for automotive parts are a type of aluminum alloy profiles specifically used in the field of automobile manufacturing. They have the remarkable characteristics of being light and high-strength. They are widely and indispensable in the production and manufacturing of many key parts such as automobile body frames, engine parts, interior trim strips, etc. The surface finishing of aluminum profiles for automotive parts is very important. The main reasons are many. First, in the production and processing of aluminum profiles for automotive parts, such as cutting, stamping, forging and other links, due to the limitations of processing parameters or the accuracy of the mold, it is easy to produce burrs on the surface. These burrs are attached to the surface of aluminum profiles like small thorns. As a high-precision product, the quality and appearance requirements of automobile parts are very high. The burrs on the surface of untrimmed aluminum profiles will seriously damage the appearance of the car. Trimming can make its surface smooth and bright, greatly improving the overall beauty and grade of the car and enhancing its market competitiveness. Secondly, automotive parts require high precision during the assembly process. Excess burrs on the surface of aluminum profiles may cause assembly difficulties and interfere with the assembly accuracy of parts. Trimming can ensure precise assembly, make the dimensional accuracy of aluminum profiles higher, ensure that parts can be accurately assembled, and improve the overall quality and safety of the car.

[0003] At present, aluminum profiles for automobile parts are usually polished by four-sided polishing machines. It consists of a precise linear conveying system and polishing components in four directions. The aluminum profile relies on a conveyor belt or a conveyor device to move steadily from one end of the machine to the other end in a straight line. During the conveying process, the four polishing surfaces of the upper, lower, left and right sides work simultaneously. The polishing head of each polishing surface is driven by a motor to rotate the polishing wheel at high speed. With the appropriate polishing medium, the surface of the aluminum profile is ground and polished to remove processing marks and burrs, improve the finish, and effectively promote the processing progress and quality improvement of aluminum profile parts in automobile production.

[0004] Existing four-sided polishing machines are usually installed horizontally. In some production workshops, especially those with limited site area but ample height space, traditional horizontally placed linear conveyor four-sided polishing machines will take up too much ground space. In terms of equipment layout, because it requires a certain length of ground space, it is easy to cause difficulties in workshop planning with limited site area. For example, when placing the equipment, it is necessary to reserve a long ground area to place it, which makes the already stretched ground space of the workshop be occupied in large quantities, and easily makes the spatial layout of the production workshop tight. Summary of the invention

[0005] The purpose of the present invention is to provide an automobile component aluminum profile surface finishing device and a finishing process to solve the problem that the existing four-sided polishing machine is usually installed horizontally, which takes up too much ground space and easily makes the space layout of the production workshop with limited site area tight.

[0015] Preferably, the back side of the support seat is provided as a guiding inclined surface, and the bottom wall of the movable groove is provided with a rotating groove for the buffer rotating plate to rotate.

[0018] B. Start the clamping assembly to move upward, thereby driving the clamped aluminum profile to move upward, and transport the aluminum profile from the bottom of the linear polishing machine to the polishing area in a vertical direction;

[0019] C. The aluminum profile passes through the linear polishing machine from bottom to top. Multiple limit frames on the surface of the linear polishing machine restrict the aluminum profile to move vertically upward. The linear polishing machine deburrs and polishes the aluminum profile.

[0020] D. When the aluminum profile is polished and removed from the upper end of the linear polishing machine, the unloading assembly will transport the polished aluminum profile away.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 12 , the present invention provides a technical solution.

[0040] A surface finishing device for aluminum profiles of automobile parts, comprising a support seat 1 and a linear polisher 2. The linear polisher 2 is vertically installed at the top end of the support seat 1. The surface of the linear polisher 2 is equipped with a plurality of limit frames 3 arranged and distributed along the vertical direction. The limit frames 3 are used to limit the moving direction of the aluminum profile. A loading assembly is installed in the support seat 1, and a unloading assembly is installed at the top end of the linear polisher 2.

[0041] The loading assembly in the support seat 1 transports the aluminum profile upward from the lower end of the linear polishing machine 2 in the vertical direction, so that the aluminum profile passes through the linear polishing machine 2 from bottom to top, and the linear polishing machine 2 performs a deburring and grinding operation on it. During this process, the movement of the aluminum profile is restricted by the limit frame 3 to ensure that it can only move vertically upward to prevent the aluminum profile from deviating from the grinding path. After grinding is completed, the aluminum profile is moved out from the upper end of the linear polishing machine 2 and then transported away by the unloading assembly.

[0042] The equipment integrates loading and unloading components, realizing the automated process of aluminum profiles from entering the equipment to starting grinding to output after grinding is completed. The loading component transports the aluminum profiles from the bottom to the grinding area in a vertical direction, reducing the labor intensity and operating errors of manual loading; the unloading component can transport the polished aluminum profiles away, avoiding manual high-altitude unloading, effectively ensuring the personal safety of operators and improving the stability and accuracy of unloading operations, which is conducive to realizing large-scale continuous production.

[0043] The feeding assembly includes a feeding track 15 and a clamping assembly. The clamping assembly can be moved up and down and installed on the surface of the feeding track 15. When the aluminum profile moves to the lower end of the linear polishing machine 2, the clamping assembly clamps the surface of the aluminum profile and then moves upward to transport the aluminum profile from the bottom to the polishing area in the vertical direction. There are two groups of feeding assemblies, and the two groups of feeding assemblies are arranged in a staggered manner so that the clamping assemblies on the two feeding assemblies do not interfere with each other when moving up and down. By setting two staggered feeding tracks 15, during continuous polishing, the two feeding assemblies alternately drive the aluminum profile to be transported upward, which can reduce the downtime of the equipment during polishing. At the same time, although the linear polishing machine 2 with its own roller to drive the aluminum profile to move and transport is provided in the prior art, there is still the possibility that the aluminum profile slides down under the action of gravity. By alternately conveying the aluminum profile upward by the two feeding assemblies, the aluminum profile conveyed upward can move one after another, and the aluminum profile at the lower end can support the aluminum profile at the upper end, further preventing the aluminum profile from sliding down under the action of gravity.

[0044] When the first clamping assembly moves up, the first aluminum profile is transported from the bottom to the polishing area in the vertical direction, and a space for an aluminum profile is vacated. Then, the second aluminum profile is placed at the bottom end of the first aluminum profile and clamped by the second clamping assembly. Then, the first clamping assembly is released, and the second clamping assembly is moved up to drive the second aluminum profile to move upward. At the same time, the first clamping assembly moves down to prepare to clamp the next aluminum profile, and so on, for continuous transportation. Because the lower end of the first aluminum profile follows the second aluminum profile, there is no need to worry that the first aluminum profile will fall out of the linear polishing machine 2.

[0045] The clamping assembly includes a loading slider 17, two electric push rods 18 and two clamping arms 19. The loading slider 17 can be moved up and down and installed on the surface of the loading rail 15. The two electric push rods 18 are rotatably arranged on both sides of the loading slider 17. The telescopic ends of the two electric push rods 18 are fixedly connected to the two clamping arms 19 respectively, and the two clamping arms 19 are symmetrically arranged. The electric push rods 18 are telescopically driven to drive the clamping arms 19 to move horizontally to achieve clamping of the aluminum profile. During the up and down movement of the two clamping assemblies, when the downward clamping assembly is operating, the electric push rod 18 is rotated to drive the clamping arms 19 to rotate to a vertical downward state. At the same time, with the help of the synergistic effect of the two electric push rods 18, the two clamping arms 19 are forced to approach each other and move toward each other, so that the distance between the two clamping arms 19 is smaller than the distance between the two clamping arms 19 corresponding to the upward clamping assembly. In this way, the purpose of the downward clamping component avoiding the upward clamping component can be achieved without interfering with the upward movement of the aluminum profile clamped by the upward clamping component.

[0046] The surface of the loading rail 15 has a sliding groove for the loading slider 17 to move up and down, and a threaded rod 16 is rotatably connected in the sliding groove. The threaded rod 16 movably penetrates the surface of the loading slider 17, and the threaded rod 16 and the loading slider 17 are threadedly connected. A second motor 21 is installed on the surface of the support seat 1. The output end of the second motor 21 movably penetrates the surface of the loading rail 15 and is coaxially fixedly connected to the end of the threaded rod 16. The threaded rod 16 is driven to rotate by starting the second motor 21. Due to the threaded action between the threaded rod 16 and the loading slider 17, the loading slider 17 can be driven to move up and down.

[0047] As required, anti-skid pads 20 are fixedly mounted on opposite ends of the two clamping arms 19 to increase the stability of the clamping arms 19 in clamping the aluminum profile.

[0048] Furthermore, the surface of the loading slider 17 is rotatably connected to a rotating disk 33, and two electric push rods 18 are respectively fixedly arranged on both sides of the loading slider 17. The surface of the rotating disk 33 is coaxially fixedly connected to a first gear 34, and the surface of the loading slider 17 is rotatably connected to a second gear 35. The second gear 35 and the first gear 34 are meshingly connected. A third motor 36 is installed on the surface of the loading slider 17, and the output end of the third motor 36 movably passes through the surface of the loading slider 17 and is coaxially fixedly connected to the second gear 35. By starting the third motor 36, the second gear 35 is driven to rotate, and the rotation of the second gear 35 drives the first gear 34 to rotate, and the rotation of the first gear 34 drives the electric push rod 18 to rotate, thereby controlling the rotation of the clamping arm 19.

[0049] In a conventional setting, the two loading assemblies are arranged in an alternating manner. Compared with the clamping arm 19 on the loading assembly that is closer to the loading position, the clamping arm 19 on the loading assembly that is farther from the loading position is longer. As long as it is ensured that no matter how far the loading track 15 is from the loading position, the clamping arm 19 can effectively clamp the aluminum profile with its corresponding length.

[0050] Furthermore, the surface of the support seat 1 is equipped with a first conveyor 11, and a plurality of aluminum profiles are vertically transmitted to the first conveyor 11, and then sequentially transported to the lower end of the linear polishing machine 2 by the first conveyor 11, so that continuous operation can be achieved. Two limit horizontal plates 12 are provided on the surface of the support seat 1, which are respectively located on both sides of the first conveyor 11. The limit horizontal plates 12 are used to prevent the aluminum profile from detaching from the surface of the first conveyor 11. Furthermore, auxiliary frames 14 are respectively installed on the two inner walls of the support seat 1, and second conveyors 22 are respectively installed on the surfaces of the two auxiliary frames 14. The second conveyor 22 can also provide a forward force to the position of the aluminum profile close to the upper end, so as to prevent the vertically placed aluminum profile from being too long and prone to tipping over only when there is forward power at the bottom.

[0051] A limit vertical plate 13 is installed on the surface of the support seat 1 , and the limit vertical plate 13 is provided to prevent the aluminum profile from crossing the lower end loading position of the linear polishing machine 2 when moving on the first conveyor 11 .

[0052] The unloading assembly includes a support rod 6, a connecting arm 7 and an electric mechanical claw 8. The support rod 6 is rotatably installed on the top of the linear polishing machine 2. The middle part of the connecting arm 7 is fixedly connected to the top of the support rod 6. The electric mechanical claw 8 is fixedly suspended on the surface of the connecting arm 7, and the electric mechanical claw 8 can be located directly above the aluminum profile moving upward. By rotating the support rod 6, the electric mechanical claw 8 can be driven to rotate accordingly, so that the electric mechanical claw 8 is placed directly above the aluminum profile moving upward. When the aluminum profile moves upward between the clamping jaws of the electric mechanical claw 8, the electric mechanical claw 8 immediately clamps the aluminum profile. At this time, the aluminum profile also happens to move out of the main body of the linear polishing machine 2 from the upper end of the linear polishing machine 2. Then the support rod 6 is rotated to drive the electric mechanical claw 8 to rotate. During the rotation, the electric mechanical claw 8 drives the clamped aluminum profile to move away, thereby making room for the next aluminum profile to move out. Then the electric mechanical claw 8 releases the clamping of the aluminum profile and rotates back to the initial position to drive the next aluminum profile to move away. According to needs, two electric mechanical claws 8 can be installed for alternating use.

[0053] The top of the linear polishing machine 2 is fixedly connected to a support frame 4, and the support frame 4 and the support rod 6 are rotatably connected. The support rod 6 is supported by the support frame 4. A first motor 5 is fixedly installed on the top of the linear polishing machine 2. The output end of the first motor 5 is coaxially fixedly connected to the bottom end of the support rod 6. The support rod 6 is driven to rotate by starting the first motor 5.

[0054] A guide track 9 is installed on the back surface of the linear polishing machine 2. The guide track 9 is used to guide the sliding direction of the aluminum profile. When the electric mechanical claw 8 rotates to drive the clamped aluminum profile to move away, the aluminum profile moves to the upper end position of the guide track 9. Then the electric mechanical claw 8 releases the clamping of the aluminum profile, allowing the aluminum profile to fall into the inner cavity of the guide track 9 and slide downward along its inner cavity. This can prevent the aluminum profile from falling in an unstable position.

[0055] A buffer component for receiving the aluminum profile is disposed on the back of the support seat 1. When the aluminum profile falls onto the buffer component along the guide track 9, the buffer component can buffer the falling potential energy of the aluminum profile to prevent the aluminum profile from being damaged due to falling.

[0056] The buffer assembly includes a buffer plate 24 and a buffer rotating plate 25. The buffer rotating plate 25 is rotatably connected to the buffer plate 24. A movable groove 28 for the buffer plate 24 and the buffer rotating plate 25 to move up and down is provided on the back of the support seat 1. A buffer spring 27 is installed between the buffer plate 24 and the groove wall of the movable groove 28. The width of the buffer rotating plate 25 is greater than the width of the aluminum profile, and the buffer rotating plate 25 is located directly below the lower opening of the guide track 9, so as to ensure that the lower end of the aluminum profile can be completely in contact with the buffer rotating plate 25 when it falls from the guide track 9. When the aluminum profile falls to the buffer rotating plate 25 When the buffer plate 24 and the buffer rotating plate 25 are lowered, the buffer rotating plate 25 can rotate, and the rotation of the buffer rotating plate 25 can guide the aluminum profile to move obliquely downward to prevent it from directly hitting the back of the support seat 1.

[0057] The back side of the support seat 1 is set as a guide slope 10, and the bottom wall of the movable groove 28 is cooperated with a rotating groove 26 for the buffer rotating plate 25 to rotate. By providing the rotating groove 26, the rotation angle of the buffer rotating plate 25 can be limited as needed, and it can be coordinated with the inclination angle of the guide slope 10 to make the aluminum profile transition naturally. When the buffer rotating plate 25 rotates to guide the aluminum profile to move obliquely downward, the aluminum profile will be guided to fall on the guide slope 10, and then slide along the surface of the guide slope 10, which can facilitate a smooth connection with the next process, and with the help of the rotation of the buffer rotating plate 25, the aluminum profile can fall smoothly to the surface of the guide slope 10, effectively preventing the occurrence of serious impact.

[0058] Both ends of the buffer rotating plate 25 are fixedly connected with connecting shafts 31, and the ends of the two connecting shafts 31 are coaxially fixedly connected with square rods 32 that penetrate the buffer plate 24. The buffer plate 24 has a circular cavity for the square rod 32 to rotate. The two side walls of the movable groove 28 are cooperated with to open square slide grooves 29 for the square rod 32 to move up and down, and the bottom walls of the two square slide grooves 29 are cooperated with to open circular rotating grooves 30 for the square rod 32 to rotate. Through such an arrangement, when the buffer rotating plate 25 and the buffer plate 24 move downward, the square rod 32 will be driven to move downward along the track of the square slide groove 29. When the square rod 32 moves from the square slide groove 29 to the circular rotating groove 30, the buffer rotating plate 25 can rotate.

[0059] A buffer torsion spring 23 is fixedly connected between the buffer rotating plate 25 and the buffer flat plate 24. By setting the buffer torsion spring 23, the buffer rotating plate 25 will twist the buffer torsion spring 23 when it rotates. When the buffer torsion spring 23 is twisted, it will generate an elastic force in the opposite direction of the twisting, thereby further buffering the aluminum profile. At the same time, after the aluminum profile slides off the buffer rotating plate 25, the buffer rotating plate 25 can automatically reset. After the buffer rotating plate 25 is reset, under the elastic force of the buffer spring 27, the buffer flat plate 24 and the buffer rotating plate 25 will move upward and reset, and can continue to buffer the next aluminum profile.

[0060] The specific scheme is as follows: loading preparation: a plurality of aluminum profiles are placed vertically on the first conveyor 11 assembled on the surface of the equipment support seat 1, and the first conveyor 11 conveys the aluminum profiles until they are blocked by the limit vertical plate 13. At this time, the aluminum profiles are at the loading position at the lower end of the linear polishing machine 2, and the first conveyor 11 is stopped. By starting the electric push rod 18 to retract, the clamping arm 19 is driven to move toward each other to clamp the aluminum profiles;

[0061] Loading process: start the second motor 21, the second motor 21 drives the threaded rod 16 to rotate, so that the rotating threaded rod 16 drives the loading slide block 17 to move upward, and then drives the clamping assembly holding the aluminum profile to move upward, and the aluminum profile is transported from the bottom of the linear polishing machine 2 to the polishing area in the vertical direction. When a space for aluminum profile is vacated, start the first conveyor 11 to transport the second aluminum profile to the loading position at the lower end of the linear polishing machine 2, and it will be at the bottom of the first aluminum profile, and then clamped by the second clamping assembly, and then release the previous clamping assembly, the second clamping assembly moves upward to drive the second aluminum profile, and at the same time the first clamping assembly moves downward to prepare to clamp the next aluminum profile, and continuous conveying is performed alternately in this way. During this period, the downward clamping assembly drives the clamping arm 19 to rotate to a vertical downward state by rotating the electric push rod 18, and the two electric push rods 18 cooperate to move the two clamping arms 19 toward each other, reducing the distance to avoid the upward clamping assembly;

[0062] Grinding operation: The aluminum profile passes through the linear polishing machine 2 from bottom to top. Multiple limit frames 3 on the surface of the linear polishing machine 2 limit the moving direction of the aluminum profile so that it can only move vertically upward. The linear polishing machine 2 performs a deburring and grinding operation on the aluminum profile;

[0063] Unloading process: After the aluminum profile is polished and moved out from the upper end of the linear polishing machine 2, the electric mechanical claw 8 clamps the aluminum profile, and then the first motor 5 is started to drive the support rod 6 to rotate. The support rod 6 rotates to rotate the electric mechanical claw 8 suspended on the surface of the connecting arm 7, driving the aluminum profile to move away, making room for the next aluminum profile to move out. When the electric mechanical claw 8 rotates and drives the aluminum profile to move to the upper end of the guide track 9, the electric mechanical claw 8 is released, and the aluminum profile falls into the inner cavity of the guide track 9, slides down along the inner cavity, and then rotates back to the initial position;

[0064] Buffering and sliding connection: the aluminum profile falls onto the buffer assembly along the guide track 9, and the lower end of the aluminum profile contacts the buffer rotating plate 25. Under the action of gravity, the buffer rotating plate 25 and the buffer flat plate 24 move downward, compressing the buffer spring 27. The buffer spring 27 generates elastic force to slow down the falling speed of the aluminum profile to achieve buffering. After the buffer flat plate 24 and the buffer rotating plate 25 descend, the buffer rotating plate 25 rotates to guide the aluminum profile to move obliquely downward. When the buffer rotating plate 25 rotates, the buffer torsion spring 23 is twisted. The buffer torsion spring 23 generates elastic force for further buffering and enables the buffer rotating plate 25 to automatically reset. The buffer rotating plate 25 rotates to make the aluminum profile fall on the guide inclined surface 10 and slide down along the surface of the guide inclined surface 10, which is convenient for connection with the next process. The connecting shafts 31 and square rods 32 at both ends of the buffer rotating plate 25 cooperate with the buffer flat plate 24 to achieve the movement and rotation of the buffer rotating plate 25 and the buffer flat plate 24.
