Description

Technical Field

[0001] This utility model belongs to the field of polishing machine technology, specifically relating to a double-head polishing auxiliary machine with a swing function. Background Technology

[0002] In modern automobile manufacturing, automated polishing processes are widely used to treat the surfaces of aluminum products such as rear quarter window trim strips and decorative panels in order to improve production efficiency and product quality, in order to achieve a bright and smooth finish.

[0003] Existing polishing auxiliary machines are typically quite simple in function, only able to install one set of cloth wheels for polishing operations. In actual operation, in order to meet specific polishing process requirements, the polishing auxiliary machine needs to perform a certain oscillating motion in the spindle direction to ensure more even contact with the product surface and improve the polishing effect.

[0004] Currently, this oscillating motion is generally achieved by controlling the A2 axis of the industrial robot to swing. However, long-term, high-frequency oscillation can damage the robot's A2 axis, increasing maintenance costs and shortening the robot's lifespan. Furthermore, due to the single-set roller operation, the rollers need to be replaced frequently, affecting overall work efficiency. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in the existing technology by proposing a double-head polishing auxiliary machine with a swing function that features a simple structure, high stability, improved polishing quality, and reduced cloth wheel replacement cycle.

[0006] This utility model can be achieved through the following technical solutions:

[0007] A dual-head polishing auxiliary machine with a swing function includes:

[0008] frame;

[0009] Both the drive mechanism and the cloth wheel are mounted on the frame. The drive mechanism is connected to the cloth wheel and is used to drive the cloth wheel to rotate.

[0010] A swing support frame is fixedly installed on both sides of the frame, and a connection structure consisting of a slider and a linear guide rail is provided between the frame and the swing support frame.

[0011] A geared motor is mounted on the frame. The output end of the geared motor is connected to the frame through a transmission assembly. When the geared motor is working, it drives the frame to reciprocate along the direction of the linear guide rail through the transmission assembly, thereby driving the cloth wheel to reciprocate synchronously.

[0012] As a further improvement of this utility model, the transmission assembly includes:

[0013] An eccentric block is disposed at the output end of the geared motor;

[0014] A mating block, which is installed inside the eccentric block;

[0015] A mounting base is provided on the frame;

[0016] The connecting rod has its two ends connected to the mating block and the fixed seat, respectively.

[0017] As a further improvement of this utility model, the eccentric block is provided with a T-shaped groove, and the mating block is set as a T-shaped block that matches the shape of the T-shaped groove. The eccentric block is driven to rotate by the reduction motor, which drives the mating block to rotate synchronously. During the rotation of the mating block, the frame is moved by the connecting rod.

[0018] As a further improvement of this utility model, the surface of the mating block has a scale for adjusting its position in the T-groove. By adjusting the position of the mating block in the T-groove, the connecting rod is driven to swing to adjust the swing distance of the frame.

[0019] As a further improvement of this utility model, the driving mechanism includes:

[0020] The main motor is housed within the frame.

[0021] The main shaft is installed inside the frame, the cloth wheels are installed at both ends of the main shaft, and the main motor is connected to the main shaft via a belt pulley drive.

[0022] As a further improvement of this utility model, the bearing for the rotation of the main shaft is configured as a sealed deep groove ball bearing.

[0023] As a further improvement of this utility model, the frame is also provided with a dustproof plate, which covers the top of the cloth wheel.

[0024] As a further improvement of this utility model, the frame is also provided with a spray gun mounting bracket, which is positioned toward the cloth wheel and used to mount the spray gun.

[0025] As a further improvement of this utility model, the top of the swing support frame is also provided with a transition plate, and the swing support frame is connected to an external industrial robot or other CNC equipment through the transition plate.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. Improve polishing quality: The robot uses a pre-programmed path to make the polishing wheel 110 fit the product. As the reciprocating oscillation mechanism starts to operate, the polishing wheel 110 begins to oscillate axially according to the preset amplitude. The high-frequency small-amplitude oscillation generates more friction between the product to be polished and the polishing wheel 110, which increases the cutting force and makes the surface of the polishing wheel 110 wear more evenly, thus further improving the polishing quality.

[0028] 2. Extend the service life of the cloth wheels: Since two sets of cloth wheels can be installed at both ends of the main shaft, not only is the working efficiency improved, but the cloth wheel replacement cycle is also effectively reduced, thus reducing maintenance costs;

[0029] 3. Reduced risk of robot damage: The robot no longer relies on the high-frequency oscillation of its A2 axis to achieve the oscillation function during the polishing process, thereby reducing the risk of damage caused by long-term high-frequency use and extending the robot's service life.

Detailed Implementation

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0037] like Figure 1-5 As shown, this utility model provides a dual-head polishing auxiliary machine with a swing function, comprising:

[0038] 100 racks;

[0039] The drive mechanism and the cloth wheel 110 are both mounted on the frame 100. The drive mechanism is connected to the cloth wheel 110 in a transmission and is used to drive the cloth wheel 110 to rotate.

[0040] The swing support frame 120 is fixedly installed on both sides of the frame 100, and a connecting structure consisting of a slider and a linear guide rail 130 is provided between the frame 100 and the swing support frame 120. The swing support frame 120 is provided to provide stable support for the swinging motion of the frame 100.

[0041] The geared motor 140 is mounted on the frame 100. The output end of the geared motor 140 is connected to the frame 100 through a transmission assembly. When the geared motor 140 is working, it drives the frame 100 to reciprocate along the direction of the linear guide rail 130 through the transmission assembly, thereby driving the cloth wheel 110 to reciprocate synchronously.

[0042] The polishing auxiliary machine provided in this embodiment has at least the following advantages:

[0043] 1. Improve polishing quality: The robot uses a pre-programmed path to make the polishing wheel 110 fit the product. As the reciprocating oscillation mechanism starts to operate, the polishing wheel 110 begins to oscillate axially according to the preset amplitude. The high-frequency small-amplitude oscillation generates more friction between the product to be polished and the polishing wheel 110, which increases the cutting force and makes the surface of the polishing wheel 110 wear more evenly, thus further improving the polishing quality.

[0044] 2. Extend the service life of cloth wheel 110: Since two sets of cloth wheels 110 can be installed at both ends of the main shaft 200, it not only improves working efficiency, but also effectively reduces the replacement cycle of cloth wheel 110 and reduces maintenance costs.

[0045] 3. Reduced risk of robot damage: The robot no longer relies on the high-frequency oscillation of its A2 axis to achieve the oscillation function during the polishing process, thereby reducing the risk of damage caused by long-term high-frequency use and extending the robot's service life.

[0046] Preferably, the transmission assembly includes:

[0047] An eccentric block 150 is located at the output end of the geared motor 140;

[0048] The mating block 160 is installed inside the eccentric block 150;

[0049] A mounting base 170 is mounted on the frame 100;

[0050] The connecting rod 180 is connected at both ends to the mating block 160 and the fixed seat 170, respectively.

[0051] Specifically, the eccentric block 150 has a T-shaped groove, and the mating block 160 is a T-shaped block that matches the shape of the T-shaped groove. When the geared motor 140 starts, its output shaft drives the eccentric block 150 to rotate. Since the central axis of the eccentric block 150 does not coincide with the output axis of the geared motor 140, the rotation of the eccentric block 150 will produce an eccentric motion. The mating block 160 will move up and down along the T-shaped groove as the eccentric block 150 rotates. As the mating block 160 moves, the connecting rod 180 pushes or pulls the frame 100, causing the frame 100 to reciprocate along the linear guide rail 130. This reciprocating motion drives the cloth wheel 110 to swing synchronously, thereby realizing high-frequency small-amplitude oscillation during the polishing process.

[0052] Preferably, the mating block 160 has a scale on its surface and is used to adjust its position in the T-groove. By adjusting the position of the mating block 160 in the T-groove, the connecting rod 180 is driven to swing to adjust the swing distance of the frame 100, thereby achieving precise control of the swing distance of the frame 100, ensuring the consistency and uniformity of the polishing process, thereby improving the surface quality and smoothness of the final product. On the other hand, it can also meet the polishing requirements of different products, improving the versatility and flexibility of the equipment.

[0053] Preferably, the drive mechanism includes:

[0054] The main motor 190 is installed inside the frame 100;

[0055] The main shaft 200 is installed inside the frame 100. The cloth wheels 110 are installed at both ends of the main shaft 200. The main motor 190 is connected to the main shaft 200 through the belt pulley 191. After the main motor 190 is started, it drives the main shaft 200 to rotate through the belt pulley 191, thereby realizing the rotation of the cloth wheels 110.

[0056] Preferably, the bearing for the rotation of the spindle 200 is a sealed deep groove ball bearing 201, which is well adapted to the working conditions of mechanical polishing.

[0057] Preferably, the frame 100 is also provided with a dustproof plate 210, which covers the top of the cloth wheel 110. The dustproof plate 210 can reduce the dust generated during the polishing process and improve the working environment of the operator.

[0058] Preferably, the frame 100 is also provided with a spray gun mounting bracket 220. The spray gun mounting bracket 220 is set towards the cloth wheel 110 and is used to mount the spray gun. By uniformly spraying coolant or lubricant through the spray gun, the temperature of the cloth wheel 110 when rotating at high speed can be effectively reduced, wear can be reduced, and the service life of the cloth wheel 110 can be extended.

[0059] Preferably, the top of the swing support frame 120 is also provided with a transition plate 230, through which the swing support frame 120 is connected to an external industrial robot or other CNC equipment.
