Description

Technical Field

[0001] The present application relates to the technical field of abrasive belt machines, and more specifically, to a movable abrasive belt mechanism, a four-station abrasive belt machine, and a control method. Background Art

[0002] A belt sander is a mechanical device used for grinding and polishing, and is widely used in woodworking and metal processing.

[0003] The belt sander uses a motor to drive a pulley to rotate, thereby driving a first sanding belt tensioned on the pulley to move, and the first sanding belt rubs against the workpiece to complete the sanding operation on the workpiece. For example, application number 202310807028.5 discloses a belt sander, including a frame, on which a first pulley, a second pulley, a third pulley, a fourth pulley, and a first sanding belt are provided; in the horizontal direction, the third pulley is located between the first pulley and the second pulley; the third pulley is located lower than the first pulley and the second pulley; the fourth pulley is lower than the second pulley, and in the horizontal direction, the second pulley and the fourth pulley are located on the same side of the third pulley. The first sanding belt of the belt sander has a first winding method, and the first sanding belt passes through the first pulley, the second pulley, the third pulley, and the fourth pulley in sequence.

[0004] At least one of its drawbacks is that the sanding belt machine is not suitable for grinding multiple workpieces at the same time, resulting in low machine efficiency. Therefore, it is necessary to design a multi-station sanding belt machine.

[0005] The technical difficulty of the multi-station sanding belt machine lies in the need to grind workpieces at multiple stations at the same time. Due to the inconsistent surface tolerances of the unground workpieces themselves, as well as the deviation in the position of the first sanding belt of the sanding belt machine itself and the inconsistent tolerance of the fixture, it is easy to cause straightness deviations between multiple workpieces and the surface of the first sanding belt when they are ground at the same time. For example, some workpieces rub closely against the surface of the first sanding belt, while some workpieces are separated from the surface of the first sanding belt, making some workpieces prone to grinding failure.

[0006] Therefore, the existing technology needs to be improved. Summary of the Invention

[0065] See also Figure 1The present embodiment provides a movable sanding belt mechanism, which includes: a main body 100, a plurality of polishing wheel assemblies 200, a plurality of rollers 300 and a Y-axis moving mechanism 400. The main body 100 includes a first sanding belt 110, which is used to connect to a workpiece 500 to grind the workpiece 500. The polishing wheel assembly 200 is movably arranged on the main body 100. The roller 300 is spaced apart from the polishing wheel assembly 200. The polishing wheel assembly 200 and the roller 300 are both used to install the first sanding belt 110, so that the first sanding belt 110 forms a plurality of convex grinding platforms 120 arranged in a straight line. The Y-axis moving mechanism 400 is driven and connected to the polishing wheel assembly 200. The Y-axis moving mechanism 400 is used to drive the polishing wheel assembly 200 to move along the Y direction to adjust the pressure between the grinding platform and the workpiece 500.

[0066] In this embodiment, a plurality of polishing wheel assemblies 200 and a plurality of rollers 300 are connected to the first abrasive belt 110 to form a plurality of convex polishing platforms 120 arranged in a straight line. The plurality of convex polishing platforms 120 arranged in a straight line can simultaneously polish a plurality of workpieces 500 to improve work efficiency. During the polishing process, the workpiece 500 can be controlled to rotate around the convex polishing platform 120, and the side of the workpiece 500 can be polished, or it can be applied to the polishing of annular, circular or spherical workpieces 500. The Y-axis moving mechanism 400 is connected to the polishing wheel assembly 200 for driving. The Y-axis moving mechanism 400 can drive the polishing wheel assembly 200 to move along the Y direction, where the Y direction refers to the direction perpendicular to the workpiece 500 when the workpiece 500 is located in front of the polishing wheel assembly 200.

[0067] Multiple unpolished workpieces 500 can be clamped by the chuck mechanism 600 at the same time and abut against the convex grinding platform 120. Due to the inconsistent surface tolerances of the workpieces 500 themselves, as well as the position deviation of the first grinding belt 110 of the grinding belt machine itself and the inconsistent fixture tolerances, it is easy to cause some workpieces 500 and the surface of the first grinding belt 110 to have straightness deviations, that is, some workpieces 500 are tightly rubbed against the surface of the first grinding belt 110, and some workpieces 500 are not tightly rubbed against or detached from the surface of the first grinding belt 110. For the workpieces 500 that are not tightly rubbed against or detached from the surface of the first grinding belt 110, the convex grinding platform 120 corresponding to the workpiece 500 will be driven by the Y-axis moving mechanism 400 to approach the workpiece 500, so that the workpiece 500 and the convex grinding platform 120 maintain a certain pressure. For example, a pressure sensor can be provided on the chuck mechanism 600, which can monitor the actual pressure F1 between the workpiece 500 and the convex grinding platform 120. The preset pressure between the workpiece 500 and the convex grinding platform 120 can be pre-set to F0. When the monitored actual pressure F1 is less than the preset pressure F0, the Y-axis moving mechanism 400 can be controlled to drive the convex grinding platform 120 toward the workpiece 500, increasing the pressure between the workpiece 500 and the convex grinding platform 120 so that the actual pressure F1 is within the range of the preset pressure F0. Alternatively, when the monitored actual pressure F1 is greater than the preset pressure F0, the Y-axis moving mechanism 400 can be controlled to drive the convex grinding platform 120 away from the workpiece 500, reducing the pressure between the workpiece 500 and the convex grinding platform 120 so that the actual pressure F1 is within the range of the preset pressure F0. When the monitored actual pressure F1 is within the preset pressure F0, the Y-axis moving mechanism 400 can be controlled to remain stationary.

[0068] Therefore, this embodiment drives the convex grinding platform 120 to move through the Y-axis moving mechanism 400, which can automatically adjust the pressure between the workpiece 500 and the convex grinding platform 120, avoid grinding failure between the workpiece 500 and the convex grinding platform 120, and realize simultaneous grinding operations of multiple workpieces 500, which can improve grinding efficiency and grinding quality.

[0069] Specifically, see Figure 2 The Y-axis moving mechanism 400 includes: a Y-direction driving source 410 and a Y-direction sliding assembly 420 . The Y-direction sliding assembly 420 is arranged along the Y-direction and is used to connect the Y-direction driving source 410 and the polishing wheel assembly 200 .

[0070] In this embodiment, the Y-direction drive source 410 is driven and connected to the polishing wheel assembly 200 via the Y-direction sliding assembly 420. For example, the Y-direction drive source 410 can drive the Y-direction sliding assembly 420 to move along the Y-direction, so as to drive the polishing wheel assembly 200 to move along the Y-direction, and then realize the movement of the convex grinding platform 120 along the Y-direction. For example, the convex grinding platform 120 can be driven to move toward the side of the workpiece 500, so that the pressure between the convex grinding platform 120 and the workpiece 500 increases, or the convex grinding platform 120 can be driven to move away from the side of the workpiece 500, so that the pressure between the convex grinding platform 120 and the workpiece 500 decreases.

[0071] Specifically, see Figure 3 The Y-direction driving source 410 includes: a Y-direction motor 411, a Y-direction screw rod 412, a sliding nut 413 and a nut sliding seat 414. The Y-direction screw rod 412 is transmission-connected to the Y-direction screw rod 412, the sliding nut 413 is threadedly connected to the Y-direction screw rod 412, and the sliding nut 413 is connected to the polishing wheel assembly 200 via the Y-direction sliding assembly 420 to realize that the Y-direction motor 411 drives the polishing wheel assembly 200 to move along the Y-direction.

[0072] In this embodiment, the Y-direction motor 411 can drive the Y-direction screw 412 to rotate, and the Y-direction screw 412 can drive the sliding nut 413 to move along the Y-direction. The sliding nut 413 can be connected to the polishing wheel assembly 200, thereby driving the polishing wheel assembly 200 to move along the Y-direction. The nut sliding seat 414 is slidably connected to the sliding nut 413 to ensure that the sliding nut 413 moves in a directional manner within the nut sliding seat 414, thereby preventing the convex polishing platform 120 from deviating during movement.

[0073] Specifically, see Figure 3 The sliding nut 413 includes: a nut body 415, a nut cap body 416 and a nut column 417. The nut body 415 is threadedly connected to the Y-direction screw rod 412.

[0074] The nut cap body 416 is triangular in shape and has a plurality of threaded holes thereon for fixed connection with the Y-direction sliding assembly 420. The nut cap body 416 is embedded in the sliding cavity 418 of the nut sliding seat 414 and is slidably connected to the sliding cavity 418.

[0075] In this embodiment, during the installation of the sliding nut 413, the nut column 417 can be inserted into the Y-direction slider 422 of the Y-direction sliding assembly 420, so that the nut cap body 416 is in contact with the Y-direction slider 422, and the installation is convenient. Therein, a number of threaded holes are provided on the nut cap body 416, and the nut cap body 416 can be fixedly connected to the Y-direction slider 422 by screws, and the nut cap body 416 is embedded in the sliding cavity 418 of the nut sliding seat 414. When the Y-direction motor 411 drives the sliding nut 413 to move, the sliding nut 413 can be directed in the sliding cavity 418 to prevent the convex grinding platform 120 from offset during movement.

[0076] Specifically, see Figure 3 The Y-direction sliding assembly 420 includes: a Y-direction slide rail 421 and a Y-direction slider 422 . The Y-direction slide rail 421 is arranged along the Y direction.

When the Y-direction motor 411 drives the Y-direction slider 422 to move, the Y-direction slider 422 drives the polishing wheel assembly 200 to move in a directional manner along the Y-direction slide rail 421.

[0078] Specifically, see Figure 3 and Figure 4 The polishing wheel assembly 200 includes: a polishing wheel base 210, a set of bearings 220 and a polishing wheel body 230.

The bearing 220 is installed on the polishing wheel base 210, and the polishing wheel body 230 is embedded in the bearing 220 and is rotatably connected to the polishing wheel base 210. A first sanding belt 110 is wound around the polishing wheel body 230. When the first sanding belt 110 moves, the polishing wheel body 230 can rotate along the polishing wheel base 210 through the bearing 220.

[0080] Specifically, see Figure 2The polishing wheel base 210 includes: a base bottom plate 211 and a base bracket 212. The base bottom plate 211 is fixed to the Y-axis slider 422 of the Y-axis moving mechanism 400, and the base bottom plate 211 is fixedly connected to the sliding nut 413 of the Y-axis moving mechanism 400. The base bracket 212 is fixed to the base bottom plate 211, and the base bracket 212 is rotatably connected to the polishing wheel body 230.

[0081] In this embodiment, the base bottom plate 211 is fixed on the Y-direction slider 422, and the base bottom plate 211 can be directed along the Y-direction slide rail 421 through the Y-direction slider 422, and the base bottom plate 211 can be fixedly connected to the nut column 417. Specifically, the nut column 417 is embedded in the base bottom plate 211.

[0082] Specifically, see Figure 4 The base bracket 212 includes: a bracket body 213, a group of long holes 214 and an upper positioning cover 215. The bracket body 213 has a bracket vertical plate 216 and a lower positioning cover 217 arranged at the bottom of the bracket vertical plate 216.

When the actual monitored pressure is greater than the preset pressure, the Y-axis moving mechanism 400 corresponding to the workpiece 500 can be controlled to drive the polishing wheel assembly 200 to move backward (away from the side of the workpiece 500) to reduce the pressure between the workpiece 500 and the first sanding belt 110; when the actual monitored pressure is less than the preset pressure, the Y-axis moving mechanism 400 corresponding to the workpiece 500 can be controlled to drive the polishing wheel assembly 200 to move forward (toward the side of the workpiece 500) to increase the pressure between the workpiece 500 and the first sanding belt 110, thereby automatically adjusting the pressure between the workpiece 500 and the convex grinding platform 120 to avoid grinding failure between the workpiece 500 and the convex grinding platform 120.

[0087] Example 3:

[0088] Based on the four-station sanding machine of the above embodiment, please refer to Figure 6 This embodiment provides a control method for a four-station sanding machine, which includes the following steps:

[0089] Presetting a preset pressure between each workpiece 500 and the convex grinding platform 120;

[0090] monitoring the actual pressure between each workpiece 500 and the convex grinding platform 120;

[0091] Determine whether the monitored actual pressure meets the pre-stored first condition. When the monitored actual pressure meets the pre-stored first condition, control the Y-axis moving mechanism 400 to drive the convex grinding platform 120 to move so that the actual pressure is within the preset pressure range. The first condition is that the actual pressure is outside the preset pressure range.

[0092] In this embodiment, a preset pressure is pre-set between each workpiece 500 and the convex grinding platform 120, and the preset pressure can be a range value. The actual pressure between each workpiece 500 and the convex grinding platform 120 is monitored. For example, the actual pressure between the workpiece 500 and the convex grinding platform 120 can be obtained by the pressure sensor on the chuck mechanism 600. The chuck mechanism 600 can include 4 clamping members, which are used to clamp the workpiece 500. Each clamping member can be provided with a corresponding pressure sensor to measure the actual pressure between the workpiece 500 and the convex grinding platform 120. When the actual pressure of a workpiece 500 is lower than the lower limit of the preset pressure, the Y-axis moving mechanism 4 corresponding to the workpiece 500 can be controlled. 00 drives the polishing wheel assembly 200 to move forward (toward the side of the workpiece 500) to increase the pressure between the workpiece 500 and the first sanding belt 110. When the actual pressure of a workpiece 500 is greater than the upper limit of the preset pressure, the Y-axis moving mechanism 400 corresponding to the workpiece 500 can be controlled to drive the polishing wheel assembly 200 to move backward (away from the side of the workpiece 500) to reduce the pressure between the workpiece 500 and the first sanding belt 110, thereby automatically adjusting the pressure between the workpiece 500 and the convex grinding platform 120 to avoid grinding failure between the workpiece 500 and the convex grinding platform 120.
