Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a grinding equipment for general mechanical equipment manufacturing. Background Technology

[0002] A grinding machine is a device that uses mechanical force and abrasives to grind, polish, and refine the surface of a workpiece, and is suitable for various processing applications. Its working principle is based on the interaction between the abrasive and the workpiece surface; the abrasive continuously rubs and grinds the workpiece surface to achieve the desired processing effect.

[0003] Belt sanders are widely used in the machining field due to their advantages of high grinding efficiency, good product quality, and ease of use. However, when using a benchtop belt sander to grind workpieces, the sanding belt cannot be adjusted in angle, which requires constantly turning the workpiece over for adjustment when grinding workpieces with beveled surfaces, increasing the workload. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for general mechanical equipment manufacturing, which can adjust the angle of the abrasive belt, and helps to grind the inclined surface of the workpiece without turning the workpiece over, thereby reducing the workload.

[0005] To achieve the above objectives, a grinding device for general mechanical equipment manufacturing is provided, comprising a base, a mounting bracket fixedly connected to the upper end of the base, a drive motor and a controller on one side of the mounting bracket, and a control mechanism on the other side of the mounting bracket. The drive motor, controller, and control mechanism are all fixedly mounted on the upper end of the base. A gearbox is fixedly connected to the end of the mounting bracket facing the control mechanism, and the output shaft of the gearbox passes through the mounting bracket and is rotatably connected to it. An adjustment motor is fixedly connected to the end of the gearbox away from the mounting bracket, and the output end of the adjustment motor is connected to the input shaft of the gearbox via a coupling. A drive wheel is provided on the side of the mounting bracket facing the control mechanism, and the drive wheel is rotatably connected to the mounting bracket via a rotating shaft. An electric push rod is located on the side of the drive wheel away from the mounting bracket, with one end of the electric push rod rotatably connected to the mounting bracket and the other end of the electric push rod fitted with a connecting block. A limiting groove penetrating the mounting bracket is provided on the mounting bracket. A transmission plate is fixedly connected to the output shaft of the gearbox, and a connecting rod is fixedly connected to the surface of the transmission plate, passing through and sliding within the limiting groove. A slide is fixedly connected to the end of the connecting rod away from the transmission plate. A grinding wheel is located between the connecting block and the slide, with its central pivot rotatably connected to the connecting block. The central part of the grinding wheel slides within the slide. A sanding belt is provided on the outer surfaces of the drive wheel and the grinding wheel, with one end of the sanding belt wrapping around the surfaces of the drive wheel and the grinding wheel and connected end-to-end. The angle of the sanding belt can be adjusted, which helps to grind the inclined surfaces of the workpiece without turning it over, reducing workload.

[0006] According to the aforementioned grinding equipment for general mechanical equipment manufacturing, the mounting frame is provided with two sets of clamping rollers on the side facing the control mechanism. Each set of clamping rollers has two rollers, and the grinding belt passes through both sets of clamping rollers. Both sets of clamping rollers clamp the inner and outer surfaces of the grinding belt. The clamping rollers fix the position of the grinding belt portion between the grinding wheel and the drive wheel, ensuring that only a portion of the grinding belt changes position when the angle of the grinding belt is adjusted, thus preventing interference between the grinding belt and the structure of the equipment.

[0007] According to the aforementioned grinding equipment for general mechanical equipment manufacturing, the output end of the drive motor is fixedly connected to a drive pulley, and the output end of the drive motor is connected to the middle of the drive pulley via a key. A driven pulley is located directly above the drive pulley, and the middle of the driven pulley is connected to the shaft of the drive wheel via a key. A belt is provided on the surfaces of the drive pulley and the driven pulley, with one end of the belt successively wrapping around the surfaces of the drive pulley and the driven pulley and connected end-to-end. A tensioning mechanism is installed on the mounting frame, and the tensioning mechanism tensions the pulleys from their outer surfaces. The belt, through the transmission between the drive pulley and the driven pulley, drives the drive wheel via the drive motor, thereby controlling the grinding belt to grind the workpiece.

[0008] According to the aforementioned grinding equipment for general mechanical equipment manufacturing, the tensioning mechanism comprises a tensioning wheel, a hand-tightening bolt, an internally threaded cylinder, and a wheel frame. The wheel frame is located on the side of the mounting frame facing the belt. The tensioning wheel is installed in the wheel frame and is rotatably connected to the wheel frame via a rotating shaft. The tensioning wheel contacts the outer side of the belt to tension it. The internally threaded cylinder is welded to the middle of the end of the wheel frame away from the belt. The hand-tightening bolt is located at one end of the mounting frame, passes through the mounting frame, and is rotatably connected to it. One end of the hand-tightening bolt extends into the internally threaded cylinder, and the hand-tightening bolt is threadedly connected to the internally threaded cylinder. Rotation of the hand-tightening bolt causes it to enter or exit the internally threaded cylinder, thereby adjusting the tension of the belt by the tensioning wheel.

[0009] According to the aforementioned grinding equipment for general mechanical equipment manufacturing, the mounting frame has a groove on its surface facing the wheel frame. A slider is fixedly connected to one end of the wheel frame facing the mounting frame, and the slider extends into the groove and is slidably connected to the groove. The cooperation between the slider and the groove improves the stability of the grinding mechanism during movement and prevents changes in the angle of the grinding mechanism from affecting its cooperation with the belt.

[0010] According to the aforementioned grinding equipment for general mechanical equipment manufacturing, a pressure sensor is installed between the electric push rod and the connecting block. The pressure sensor detects the squeezing force exerted on the connecting block by the electric push rod and the grinding belt, and is used to detect whether the grinding belt is tensioned. The pressure sensor enables the electric push rod to automatically tension the grinding belt, avoiding the need for manual adjustment of the tension after the angle of the grinding belt has been adjusted.

[0011] The above solution has the following advantages: by increasing the output torque of the motor through the gearbox, the transmission plate is driven to rotate, causing the grinding wheel to rise or fall. In conjunction with the clamping roller to limit the grinding belt, the belt located on the side of the clamping roller away from the drive roller tilts upward or downward, thereby fitting against the upper or lower inclined surface of the workpiece for grinding, reducing the need to turn the workpiece over, and reducing the workload.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

The connecting rod 22 passes through the limiting groove 23 and slides in the limiting groove 23. A slide 14 is fixedly connected to the end of the connecting rod 22 away from the transmission plate 19. A grinding wheel 13 is provided between the connecting block 2 and the slide 14. The central shaft of the grinding wheel 13 is rotatably connected to the connecting block 2. The central part of the grinding wheel 13 slides in the slide 14. A grinding sand belt 1 is provided on the outer surface of the drive wheel 9 and the grinding wheel 13. One end of the grinding sand belt 1 passes around the surface of the drive wheel 9 and the grinding wheel 13 and is connected end to end.

[0023] The mounting bracket 7 has two sets of clamping rollers 4 on the side facing the control mechanism 6. Each set of clamping rollers 4 has two rollers, through which the abrasive belt 1 passes. Both sets of clamping rollers 4 clamp the inner and outer surfaces of the abrasive belt 1. The clamping rollers 4 fix the position of the abrasive belt 1 between the grinding wheel 13 and the drive wheel 9, ensuring that only a portion of the abrasive belt 1 changes position when the angle is adjusted, thus preventing interference between the abrasive belt 1 and the equipment structure.

[0024] A drive pulley 17 is fixedly connected to the output end of the drive motor 8, and the output end of the drive motor 8 is connected to the middle of the drive pulley 17 via a key. A driven pulley 15 is located directly above the drive pulley 17, and the middle of the driven pulley 15 is connected to the shaft of the drive wheel 9 via a key. A belt 20 is provided on the surface of the drive pulley 17 and the driven pulley 15, and one end of the belt 20 passes around the surface of the drive pulley 17 and the driven pulley 15 in sequence and is connected end to end. A tensioning mechanism 16 is installed on the mounting bracket 7, and the tensioning mechanism 16 tensions the pulleys from the outer surface of the pulleys. The belt 20 drives the drive motor 8 to drive the drive wheel 9 through the drive pulley 17 and the driven pulley 15, thereby controlling the grinding belt 1 to grind the workpiece.

[0025] The tensioning mechanism 16 consists of a tensioning wheel 24, a hand-tightening bolt 26, an internally threaded cylinder 27, and a wheel frame 28. The wheel frame 28 is located on the side of the mounting frame 7 facing the belt 20. The tensioning wheel 24 is installed in the wheel frame 28 and is rotatably connected to the wheel frame 28 via a rotating shaft.

The hand-tightening bolt 26 is located at one end of the mounting frame 7 and passes through the mounting frame 7, rotatably connecting to the mounting frame 7. One end of the hand-tightening bolt 26 extends into the internally threaded cylinder 27 and is threadedly connected to the internally threaded cylinder 27.

A slider 25 is fixedly connected to one end of the wheel frame 28 facing the mounting bracket 7, and the slider 25 extends into the groove 21 and is slidably connected to the groove 21. The cooperation between the slider 25 and the groove 21 improves the stability of the grinding mechanism when it moves, and prevents the angle of the grinding mechanism from changing, which would affect the cooperation with the belt 20.

[0027] A pressure sensor 3 is installed between the electric push rod 10 and the connecting block 2. The pressure sensor 3 detects the squeezing force exerted on the connecting block 2 by the electric push rod 10 and the abrasive belt 1, and is used to detect whether the abrasive belt 1 is tensioned. The pressure sensor 3 enables the electric push rod 10 to automatically tension the abrasive belt 1, avoiding the need for manual adjustment of the tension after the angle of the abrasive belt 1 is adjusted.

[0028] Working principle: During use, depending on whether the inclined surface of the workpiece to be ground is an upper or lower inclined surface, the adjusting motor 12 is activated and its rotation direction is changed. The gearbox 11 increases the output torque of the adjusting motor 12, which drives the transmission plate 19 to tilt upward or downward, causing the grinding wheel 13 to rise or fall. With the limit of the belt 20 by the clamping roller 4, the grinding belt 1 located on the side of the clamping roller 4 away from the drive roller tilts upward or downward. Then, the workpiece is brought close to the grinding belt 1, and the angle of the grinding belt 1 is adjusted by the adjusting motor 12 until the grinding belt 1 is in contact with the inclined surface of the workpiece. Then, the electric push rod 10 extends and drives the grinding wheel 13 to move through the connecting block 2, which tensions the grinding belt 1. The pressure sensor 3 detects the tension of the grinding belt 1. Finally, the drive motor 8 is activated, and the drive wheel 9 drives the grinding belt 1 to grind the workpiece through the belt 20.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
