Description

Technical Field

[0001] The present invention relates to the technical field of metal surface treatment, and more specifically, to an automatic polishing device. Background Art

[0002] In the production process of round tubes, there is a surface polishing process. Whether it is a straight tube or a bent tube, especially for a bent tube with a curvature, if manual polishing is used, not only is the polishing efficiency low, but also the labor cost is high. In the prior art, polishing equipment is often used to polish bent tubes. The polishing equipment is usually set such that the polishing wheel rotates at a high speed, and there is a moving mechanism to transport the bent tube to the polishing wheel. When the bent tube contacts the polishing wheel, it rotates and displaces simultaneously, and the polishing wheel can perform full polishing on the outer surface of the bent tube.

[0003] However, the applicant has found that for the polishing equipment in the prior art, when polishing a bent tube with a curvature, since the polishing wheel usually rotates at a fixed position and relies on the self-rotation of the bent tube for surface grinding, and due to the irregular shape of the bent tube, in actual situations, the bent tube needs to be clamped on the moving mechanism in different position states for at least two grindings to ensure that all surface positions of the bent tube are ground, resulting in low polishing efficiency. In addition, during the polishing process, it is easy to have the problem that the polishing degree of the same bent tube is different, which cannot guarantee the polishing accuracy, and the surface defect rate is high, affecting the product quality.

[0004] Therefore, how to solve the problems of high surface defect rate and low polishing efficiency of the bent tubes polished by the polishing equipment in the prior art has become an important technical problem to be solved by those skilled in the art. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

For example, it 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 directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] The purpose of this specific embodiment is to provide an automatic polishing device, which can solve the problems of high defective rate of the surface effect of the polished elbow pipe and low polishing efficiency in the existing polishing devices.

[0049] Hereinafter, the embodiments will be described in detail with reference to the drawings. In addition, the embodiments shown below do not limit the content of the invention described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the invention described in the claims.

[0050] Please refer to Figures 1-2, an automatic polishing device provided in this embodiment includes a base 1, a turntable 2 rotatably connected to the base 1, a main driving mechanism for driving the turntable 2 to rotate back and forth, a polishing module 3 provided on the turntable 2 and used for polishing a round tube, and a manipulator for clamping the round tube and driving the round tube to displace. The polishing module 3 includes a polishing structure and a polishing power mechanism for driving the polishing structure to generate friction with the round tube. There are at least two groups of polishing modules 3, and all polishing structures are annularly arrayed around the rotation axis of the turntable 2. In this embodiment, three groups of polishing modules 3 are taken as an example for illustration, that is, the angle between each group of polishing modules 3 is 120°. The turntable 2 swings and rotates within a range of plus or minus 15°. The manipulator is selected as a common six-axis manipulator in the prior art. With such a setting, after the manipulator grabs a bent pipe product from the bin, it clamps the bent pipe and aligns it with the central position formed by all the polishing structures. The polishing power mechanism drives the polishing structure to rotate at a high speed. The manipulator drives the bent pipe to move along a trajectory set according to the shape of the bent pipe. At the same time, the main driving mechanism controls the turntable 2 to rotate back and forth within a certain angle range to form a swinging shape. The annularly arrayed polishing structures surround the circumference of the bent pipe. Driven by the turntable 2, the positions of the polishing structures change back and forth to complete the uniform polishing of the bent pipe. When the product trajectory reaches the end point, the manipulator then walks back along the product trajectory in the reverse direction. When it reaches the starting position of the product, the polishing module 3 stops operating. The manipulator puts the polished product back into the bin. After putting down the product, it moves above another product and grabs the material for polishing. This process is repeated in sequence. In this way, not only is the polishing efficiency high, but also the frequency of receiving polishing at each position of the bent pipe is the same, and the polishing is uniform, solving the problems of high defective rate of the surface effect of the bent pipe polished by the polishing equipment in the prior art and low polishing efficiency.

[0051] It should be noted that this automatic polishing device is not only applicable to the surface processing of straight pipes and bent pipes in round tubes, but also applicable to bathroom hardware, kitchen utensils, locks, etc.

[0052] As a specific embodiment, please refer to Figures 3-4, the turntable 2 is connected to the base 1 through a guide rail and pulley structure. The guide rail and pulley structure includes: a circular or arc-shaped main guide rail 5; a pulley group, including a plurality of deep groove ball bearings 6 slidingly connected to the inner ring of the main guide rail 5 and / or a plurality of pulleys 7 slidingly connected to the outer ring of the main guide rail 5. One of the base 1 and the turntable 2 is provided with the main guide rail 5, and the other is provided with a pulley group, and relative reciprocating sliding is generated between the main guide rail 5 and the pulley group. Specifically, it can be set that the main guide rail 5 is installed on the turntable 2, and the straight line where the axial direction of the main guide rail 5 is located coincides with the rotation axis of the turntable 2. Both the deep groove ball bearings 6 and the pulleys 7 are provided and installed on the base 1. The driving mechanism drives the turntable 2 and the base 1 to rotate relatively reciprocally, and relative reciprocating sliding is generated between the main guide rail 5 and the pulley group. With such a setting, both the deep groove ball bearings 6 and the pulleys 7 limit the main guide rail 5, and the turntable 2 can only rotate along the main guide rail 5 or the pulley group, and the relative sliding generated between the main guide rail 5 and the pulley group takes the main guide rail 5 itself as the trajectory.

[0053] Moreover, a groove 501 is provided on the inner ring of the main guide rail 5, and the deep groove ball bearing 6 is located in the groove 501 and generates relative sliding with the main guide rail 5. With such a setting, while the plurality of deep groove ball bearings 6 generate relative sliding within the inner ring of the main guide rail 5, a separation prevention structure that can prevent the two from separating in the horizontal direction is formed. In addition, a conical outer edge 502 protruding outward is provided on the outer ring of the main guide rail 5, and the pulley 7 is provided with a conical groove that fits the outer edge 502. With such a setting, the sliding fit between the main guide rail 5 and the pulley 7 is stable and reliable.

[0054] In a more specific embodiment, in order to facilitate the movement of the manipulator holding the bent pipe between the grinding structures on the turntable 2, the turntable 2 is provided with a first vacant opening and is in the shape of a fan ring with an acute central angle. The base 1 is provided with a second vacant opening corresponding to the first vacant opening. The main guide rail 5 is distributed along the turntable 2 and is arc-shaped. With such a setting, the turntable 2 and the base 1 are in a C shape, and the vacant parts on the turntable 2 and the base 1 provide a passing position for the manipulator, facilitating the movement of a longer bent pipe or other products along a set trajectory, and ensuring better assembly connection and coordinated use of the various structures in this automatic polishing equipment.

[0055] In a more specific embodiment, a strip groove 8 is provided on the turntable 2, and the main drive mechanism includes a first motor structure 9 mounted on the base 1, a sliding swing arm block 10 slidably connected to the strip groove 8, and a crank connecting rod structure connected between the first motor structure 9 and the sliding swing arm block 10, so that the first motor structure 9 drives the sliding swing arm block 10 to move back and forth along the strip groove 8, and the first motor structure 9 has a reduction motor. Due to the limiting guide effect formed by the cooperation between the main guide rail 5 and the pulley block, the turntable 2 can only slide along the pulley block and produce relative rotation with the base 1. Therefore, when the sliding swing arm block 10 moves in the strip groove 8, the force generated in other directions is transmitted to the turntable 2, which can only cause it to rotate back and forth within a small range. The turntable 2 is set to swing and rotate within a range of plus or minus 15 degrees. The crank-connecting rod structure includes a rocking eccentric 11, a seated outer spherical bearing 12, a connecting rod 13, and a spherical bearing 14. The first end of the rocking eccentric 11 is connected to the output shaft of the first motor structure 9. The first end of the connecting rod 13 is hinged to the second end of the rocking eccentric 11 via the seated outer spherical bearing 12. The second end of the connecting rod 13 is hinged to the sliding swing arm block 10 via the spherical bearing 14. The rotation axis of the rocking eccentric 11 and the rotation axis of the sliding swing arm block 10 are parallel to each other. This arrangement has a compact structure and flexible transmission.

[0056] As an alternative embodiment, please refer to Figures 5-6 The polishing module 3 also includes a first module housing 306, which is provided with a polishing structure including a polishing wheel 301. The polishing power mechanism includes a driven wheel 302 coaxially connected to the polishing wheel 301, a driving wheel 303 connected to the driven wheel 302 via a synchronous belt 305, and a second motor structure 304 that drives the driving wheel 303 to rotate. The driving wheel 303, the driven wheel 302, and the synchronous belt 305 are located in the first module housing 306, and the polishing wheel 301 and the second motor structure 304 are located outside the first module housing 306. The polishing wheel 301 can be, but is not limited to, a cloth wheel, a hemp wheel, a dry leaf wheel, a wing wheel, a nylon wheel, etc. The second motor structure 304 can be configured as a brake servo motor. This configuration makes the automatic polishing equipment more suitable for the types of products that need to be polished by the polishing wheel 301.

[0057] In addition, a second motor structure 304 is provided to communicate with the controller, and the controller controls the forward and reverse switching of the second motor structure 304 according to the torque of the second motor structure 304. During operation, the torque of each second motor structure 304 can be obtained in real time through the numerical control system where the controller is located, and the rotation direction of the polishing wheel 301 can be changed according to the different positions of the product to be polished, thereby saving polishing consumables.

[0058] As a preferred embodiment, please refer to Figures 5-6, it is provided that the automatic polishing device further includes a compensation module 4 for adjusting the radial distance of the grinding structure relative to the rotation axis of the turntable 2. The compensation module 4 is provided with several groups corresponding one-to-one with the polishing modules 3, that is, three groups are provided. With such a setting, since the grinding structure is a consumable, when the grinding structure is worn due to long-term use, or when there is a difference in size between the currently ground product and the previous product, the compensation module 4 can make up for the small gap between the grinding structure and the product, preventing the situation where the grinding structure is not in sufficient contact with the product.

[0059] Furthermore, the compensation module 4 is provided to include an auxiliary guide rail 401 fixed on the turntable 2 and having a length direction parallel to the moving direction of the grinding structure, an auxiliary slider 402 slidably connected to the auxiliary guide rail 401, a moving plate 403 fixed on the auxiliary slider 402, a ball screw structure 404 installed on the turntable 2, a third motor structure 405 for driving the moving plate 403 to reciprocate through the ball screw structure 404, and a second module housing 406. The ball screw structure 404, the auxiliary guide rail 401, and the auxiliary slider 402 are located in the second module housing 406. The moving plate 403 is slidably connected to the second module housing 406 and is connected with dust covers at both ends to hermetically shield the ball screw structure 404, the auxiliary guide rail 401, and the auxiliary slider 402. The third motor structure 405 is located outside the second module housing 406. The ball screw structure 404 is composed of a screw, a nut, steel balls, preloading sheets, a reverser, a dust protector, etc. Since it is a commonly used transmission element in the prior art, the detailed structure will not be elaborated here. The third motor structure 405 drives the screw to rotate. The moving plate 403 is fixed on the nut, and the polishing module 3 is connected to the moving plate 403. The third motor structure 405 is communicatively connected to the second motor structure 304 of the grinding power mechanism through a controller. The controller controls the operation and stop of the third motor structure 405 according to the torque of the second motor structure 304 of the grinding power mechanism. The manipulator is also communicatively connected to the controller. The third motor structure 405 can be set as a brake servo motor. In the actual application process, the torques of the three second motor structures 304 are monitored through the numerical control system where the controller is located. According to the torque feedback, each third motor structure 405 makes a reaction, and each polishing module 3 performs automatic forward or backward compensation without manual compensation until the polishing wheel 301 is used until the minimum diameter of the polishing wheel 301 set in advance in the numerical control system is reached. The numerical control system automatically alarms to remind to replace the grinding consumables and automatically returns to the maximum diameter position set in the numerical control system.

[0060] In the above embodiments, the working process of the automatic polishing equipment is as follows: at the beginning of grinding the product, while the three polishing wheels 301 are rotating, under the movement of the compensation module 4, they are pressed down to approach the product. After reaching the torque value set by the numerical control system where the controller is located, the manipulator starts to move along the product trajectory; when it reaches the starting position of the product again, that is, when the grinding is finished, the three polishing wheels 301, under the movement of the compensation module 4, retreat to the set position and stop rotating. The manipulator is also communicatively connected to the controller.

[0061] As a preferred embodiment, the automatic polishing equipment is further provided with a buffer and shock absorption structure between the main drive mechanism and the base 1, so as to absorb the machine vibration generated by the main drive mechanism, thereby preventing structural looseness and reduced rotational connection fit between the turntable 2 and the base 1 due to long-term vibration.

[0062] As an alternative embodiment, a rubber spring 15 is provided on the sliding swing arm block 10, and an arc-shaped slot 16 is provided on the base 1. The rubber spring 15 passes through the turntable 2 and is located in the arc-shaped slot 16. The rubber spring 15 slides along the arc-shaped slot 16 under the drive of the sliding swing arm block 10. The rubber spring 15 is located at the position where the drive mechanism transmits vibration to the main guide rail 5 and the pulley group, so as to block the vibration from being transmitted along the base 1 and the turntable 2 to the main guide rail 5 and the pulley group. The rubber spring 15 is in sliding contact with the arc-shaped slot 16 on the base 1, can be subjected to multi-directional loads at the same time, absorb vibration, and buffer and shock absorb. In this way, the rubber spring 15 functions as a buffer and shock absorption structure.

For the content not detailed in some embodiments, reference can be made to the same or similar content in other embodiments. The multiple solutions provided by the present invention include the basic solutions of themselves, which are independent of each other and do not restrict each other.
