Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding equipment technology, and in particular to a sanding belt anti-deviation installation structure. Background Technology
[0002] Abrasive belts, as important flexible grinding tools, are widely used in various grinding equipment. However, belt misalignment is a long-standing problem during operation. Belt misalignment refers to the phenomenon where the abrasive belt deviates from its preset track and moves axially during transmission. Misaligned belts cause abnormal friction and scraping against the machine frame, not only rapidly wearing down the belt edges and causing premature breakage, but also damaging expensive rollers and bearings, increasing maintenance costs. Secondly, belt misalignment directly leads to deterioration of processing quality. The unstable contact area between the belt and the workpiece prevents uniform grinding, easily causing defects such as chatter marks and grooves on the workpiece surface, and even leading to dimensional deviations and increased scrap rates. Utility Model Content
[0003] This utility model addresses the issue of belt misalignment during existing belt grinding processes by proposing a belt misalignment prevention installation structure to alleviate the problem.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The first end of the adjusting rod is fixedly connected to the movable working end of the adjusting cylinder. The deflection guide plate is fixedly installed on the second bracket, and a guide groove is provided on the deflection guide plate. The extension direction of the guide groove forms an angle with the axis of the adjusting cylinder.

[0006] Preferably, the sanding belt anti-deviation installation structure also includes a sliding seat, on which a sliding groove is provided. The extension direction of the sliding groove is parallel to the axis of the adjusting cylinder. A slider is fixedly connected to the adjusting rod, and the slider matches the sliding groove to form a sliding connection between the adjusting rod and the sliding seat.
[0007] Preferably, the guide block is a cylinder, and the guide block is rotatably connected to the adjusting rod.
[0008] Preferably, the width of the guide groove corresponds to the outer diameter of the guide block.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-2 A sanding belt anti-deviation installation structure includes a first bracket 1 and a second bracket 2. The second bracket 2 is located above the first bracket 1, and a second belt roller 3 is rotatably connected to the second bracket 2. A first belt roller 4 is installed at the bottom of the first bracket 1 and is rotatably connected to the first bracket 1 via a first rotating shaft 41. The first belt roller 4 and the second belt roller 3 are arranged parallel to each other. The sanding belt 16 is sleeved between the second belt roller 3 and the first belt roller 4, and the second belt roller 3 and the first belt roller 4 support and convey the sanding belt 16.
[0023] Furthermore, the second support 2 is connected to the first support 1 via a support cylinder 15. The axis of the support cylinder 15 is perpendicular to the axis of the second belt roller 3. The support cylinder 15 drives the second support 2 to move relative to the first support 1, thereby adjusting the distance between the second belt roller 3 and the first belt roller 4 to achieve tensioning of the abrasive belt 16. In this embodiment, the axes of the second belt roller 3 and the first belt roller 4 are horizontally arranged, while the axis of the support cylinder 15 is vertically arranged.
[0024] Furthermore, the anti-deviation installation structure for the abrasive belt in this embodiment also includes a third bracket 11, which is integrally cast with the first bracket 1. A motor 13 is fixedly mounted on the third bracket 11. The output shaft of the motor 13 is fixedly connected to a second rotating shaft 141 via a coupling. The second rotating shaft 141 is rotatably connected to the third bracket 11, and a drive wheel 14 is fixedly sleeved on the second rotating shaft 141. A first rotating shaft 41 at one end of the first belt roller 4 extends to the third bracket 11 and is rotatably connected to it. A rotating wheel 42 is fixedly sleeved on the first rotating shaft 41. (Reference) Figure 4 The second rotating shaft 141 is arranged parallel to the first rotating shaft 41, and the rotating wheel 42 is connected to the drive wheel 14 by a synchronous belt 12 to realize the synchronous rotation of the rotating wheel 42 and the drive wheel 14.
[0025] In this embodiment, both the rotating wheel 42 and the drive wheel 14 are gears, the synchronous belt 12 is a toothed belt, and the motor 13 is a servo motor. The motor 13 drives the rotation of the drive wheel 14, thereby realizing the rotation of the rotating wheel 42 and the first belt roller 4. (Reference) Figure 3 The sanding belt 16 is tightly fitted between the first belt roller 4 and the second belt roller 3. The rotation of the first belt roller 4 can generate the rotation of the second belt roller 3 and the conveying action of the sanding belt 16, thereby realizing the sanding work of the sanding belt 16.
[0026] In this embodiment, the first belt roller 4 is a rubber roller, and rubber has a high coefficient of friction. As the drive wheel, the first belt roller 4 can generate frictional force with the sanding belt 16, transmitting torque to the sanding belt 16 to a large extent, preventing slippage and ensuring smooth operation. Simultaneously, the rubber's elasticity absorbs vibrations generated when the sanding belt 16 contacts the workpiece, making the grinding process smoother and improving surface finish. The second belt roller 3 is a steel roller. Steel rollers have high hardness and are not easily deformed, ensuring system rigidity. Furthermore, the good thermal conductivity of metal helps dissipate the heat generated by the sanding belt 16 during grinding.
[0027] Furthermore, the anti-deviation installation structure for the sanding belt in this embodiment includes an anti-deviation structure, which comprises an adjusting cylinder 5, an adjusting rod 6, and a deflection guide plate 8. The adjusting cylinder 5 is fixedly installed on the first bracket 1 via a fourth bracket 10, and the axis of the adjusting cylinder 5 is parallel to the axis of the supporting cylinder 15. The upper end of the adjusting cylinder 5 is a movable working end, and the first end of the adjusting rod 6 is fixedly connected to the upper end of the adjusting cylinder 5. The adjusting cylinder 5 is used to drive the adjusting rod 6 to move in the vertical direction.
[0028] The aforementioned deflection guide plate 8 is fixedly connected to the side of the second bracket 2. A guide groove 81 is provided on the deflection guide plate 8. The second end of the adjusting rod 6 extends above the first bracket 1, and a guide block 62 is rotatably connected to the second end of the adjusting rod 6. The guide block 62 is cylindrical and rotatably connected to the adjusting rod 6. The guide block 62 is located inside the guide groove 81, and the width of the guide groove 81 corresponds to the outer diameter of the guide block 62. The guide block 62 can slide inside the guide groove 81, forming a sliding connection between the guide block 62 and the deflection guide plate 8.
[0029] In this embodiment, the guide groove 81 is inclined, that is, the extension direction of the guide groove 81 forms an angle with the vertical direction. When the guide block 62 moves in the vertical direction, the guide block 62 can push the deflection guide plate 8 to deflect.
[0030] In this embodiment, a sliding seat 7 is fixedly provided on the side of the first bracket 1. The sliding seat 7 is provided with a sliding groove that extends vertically. A slider 61 is fixedly connected to the adjusting rod 6. The slider 61 matches the sliding groove to form a sliding connection between the adjusting rod 6 and the sliding seat 7. The sliding seat 7 is used to guide the adjusting rod 6 vertically, which is beneficial for the stable movement of the adjusting rod 6 in the vertical direction.
[0031] This anti-deviation installation structure for the sanding belt also includes a controller and a hydraulic-electric control valve. The hydraulic-electric control valve controls the working state of the adjusting cylinder 5 by controlling the flow direction and flow rate of hydraulic oil. An optical sensor 9 is fixedly installed on the top of the first bracket 1. The optical sensor 9 is electrically connected to the signal input terminal of the controller, and the hydraulic-electric control valve is electrically connected to the signal output terminal of the controller. The optical sensor 9 is used to detect the position of the sanding belt 16. The optical sensor 9 has a built-in light emitter and light receiver. The light emitter emits infrared light, which is reflected by the sanding belt 16 and then detected by the light receiver, thus determining the position of the sanding belt 16. The optical sensor 9 can convert the light signal into an electrical signal, forming a control signal. The controller can adjust the working state of the adjusting cylinder 5 by regulating the hydraulic-electric control valve.
[0032] In this embodiment, the working principle of the sanding belt anti-deviation installation structure is as follows: the motor 13 drives the drive wheel 14 to rotate, and the drive wheel 14 drives the rotating wheel 42 and the first belt roller 4 to rotate via the synchronous belt 12, thereby forming the conveying action of the sanding belt 16 and realizing the sanding work of the sanding belt 16. During the sanding process, the sanding belt 16 may deviate from its position. The optical sensor 9 can detect the position of the sanding belt 16. When the sanding belt 16 deviates, the optical sensor 9 can generate a control signal, and the controller controls the working state of the adjusting cylinder 5. The adjusting cylinder 5 can drive the adjusting rod 6 to move in the vertical direction. The guide block 62 can slide inside the guide groove 81. The guide block 62 pushes the deflecting guide plate 8 in the vertical direction to adjust the position of the second bracket 2 and the second belt roller 3. The second belt roller 3 can wobble slightly, giving the sanding belt 16 a lateral force that runs inward (for example, if the sanding belt 16 runs in the first direction, the end of the second belt roller 3 in the first direction is raised), thereby preventing the sanding belt 16 from running off-center or correcting the sanding belt 16 from running off-center.
[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
