Description

Technical Field

[0001] This utility model relates to the field of mechanical parts manufacturing technology, and in particular to a tension adjustment device for a polishing wheel for parts. Background Technology

[0002] Polishing is an important process in machining, which can improve the surface finish of parts, remove surface defects, improve appearance quality, or enhance certain functional characteristics. During polishing, a drive motor drives the polishing assembly to rotate, which in turn drives the polishing belt, drive shaft, and drive wheel to rotate successively. Thus, the polishing belt continuously moves to polish the parts. Since the polishing belt will wear out after long-term operation, it will affect the polishing effect. It is necessary to adjust the tension of the polishing belt in a timely manner. The existing adjustment method is cumbersome and will affect the downtime of the polishing machine and the polishing efficiency.

[0003] To address the aforementioned issues, a tension adjustment device for a polishing wheel for parts has been developed. Utility Model Content

[0005] The technical solution of this utility model is as follows: a tension adjustment device for a polishing wheel of a part, comprising a base, a motor mounted on the upper rear side of the base, a polishing assembly connected to the output shaft of the motor, the polishing assembly including a driving wheel, a driven wheel, a polishing belt, and a transmission shaft, the transmission shaft being connected to the output shaft of the motor, the transmission shaft also being rotatably connected to the left front part of the base, the driving wheel being connected to the right side of the transmission shaft, the driven wheel being connected to the left side of the transmission shaft, the polishing belt being sleeved between the driven wheel and the driving wheel, the motor output shaft being rotatably connected to the front part of the base, the polishing assembly being rotatably connected to the front part of the base, and a tension adjustment device mounted on the front part of the base. The tension adjustment assembly includes a connecting platform, which is connected to the upper part of the base. A bracket is connected to the upper rear side of the connecting platform. A positioning pin is slidably connected between the left and right sides of the bracket. A slide rod is connected to the upper front side of the connecting platform. A tensioning rod is slidably connected to the slide rod. A directional handle is also slidably connected to the slide rod. The directional handle is located below the tensioning rod. The rear side of the directional handle is in contact with the positioning pin. A lead screw is rotatably connected to the directional handle. The lead screw is threadedly connected to the tensioning rod. A rocker arm is connected to the upper part of the lead screw. A tensioning wheel is rotatably connected to the front of the tensioning rod. The tensioning wheel is in contact with the polishing belt.

[0006] Further explanation: It also includes a calibration mechanism, which includes a connecting plate. The connecting plate is connected to the tension adjustment assembly. The connecting plate is connected to the tension adjustment assembly by two first bolts. A connecting pipe is connected to the connecting plate. A calibration plate is connected to the front side of the connecting pipe. Alignment wheels are rotatably connected to both the front and rear parts of the calibration plate. The alignment wheels are slidably connected to the polishing belt.

[0007] Further explanation: It also includes a shock absorption mechanism, which includes a first pressure plate. The first pressure plate is connected to both the upper and lower sides of the front of the drive shaft. The second pressure plate is connected to both the upper and lower sides of the front of the drive wheel by a second bolt. The second pressure plate is also connected to both the upper and lower sides of the front of the driven wheel by a second bolt.

[0009] To further clarify, the connecting pipe is made of a rigid material.

[0010] To further explain, the first pressure plate and the second pressure plate can provide buffering and shock absorption for the drive shaft, the driving wheel, and the driven wheel.

[0011] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model is equipped with a tension adjustment component, a sliding directional handle, and a positioning pin for locking and positioning. The movement of the directional handle drives the tension rod and tension wheel to move. The tension wheel presses against the polishing belt, thereby adjusting the polishing belt to a suitable tension state. At the same time, the rocker arm can be rotated to make the lead screw rotate, which in turn drives the tension rod and tension wheel to move, thereby fine-tuning the position of the tension wheel. This helps to enhance the accuracy of the tension wheel pressing down on the polishing belt, making it easier to adjust the polishing belt to a more precise tension level, which helps to ensure the polishing effect.

[0013] 2. This utility model is equipped with a calibration mechanism. By fixing the position of the centering wheel, the centering wheel limits the polishing belt, so that the polishing belt will be in a central moving position. At the same time, a shock absorption mechanism is set up to absorb the shock of the adjacent first pressure plate and second pressure plate through dampers and springs, thereby enhancing the overall stability of the device.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0021] Example 1

[0022] A tension adjustment device for a polishing wheel for parts, such as Figure 1 and Figure 2As shown, the system includes a base 1, a motor 2 mounted on the upper rear side of the base 1, and a polishing assembly 3 connected to the output shaft of the motor 2. The polishing assembly 3 includes a drive wheel, a driven wheel, a polishing belt, and a drive shaft. The output shaft of the motor 2 is connected to the drive shaft. A drive shaft is also rotatably connected to the left front of the base 1. A drive wheel is connected to the right drive shaft, and a driven wheel is connected to the left drive shaft. A polishing belt is fitted between the driven wheel and the drive wheel. The output shaft of the motor 2 is rotatably connected to the front of the base 1, and the polishing assembly 3 is rotatably connected to the front of the base 1. A tension adjustment assembly 4 is mounted on the front of the base 1, and the tension adjustment assembly 4 includes a connecting platform 41. The connecting platform 41 is connected to the upper part of the base 1. A bracket 42 is connected to the upper rear side of the connecting platform 41. A positioning pin 43 is slidably connected between the left and right sides of the bracket 42. A slide rod 45 is connected to the upper front side of the connecting platform 41. A tensioning rod 46 is slidably connected to the slide rod 45. A directional handle 44 is also slidably connected to the slide rod 45. The directional handle 44 is located below the tensioning rod 46. The rear side of the directional handle 44 is in contact with the positioning pin 43. A lead screw 47 is rotatably connected to the directional handle 44. The lead screw 47 is threadedly connected to the tensioning rod 46. A rocker arm 48 is connected to the upper part of the lead screw 47. A protective sleeve is provided on the rocker arm 48. A tensioning wheel 49 is rotatably connected to the front of the tensioning rod 46. The tensioning wheel 49 is in contact with the polishing belt.

[0023] It should be noted that parts polishing is an important process in machining, which can improve the surface finish of parts, remove surface defects, improve appearance quality, or enhance certain functional characteristics. During parts polishing, motor 2 is first started. The output shaft of motor 2 rotates, driving the right-side drive shaft, which in turn rotates the drive wheel, subsequently driving the polishing belt, driven wheel, and left-side drive shaft to rotate. This continuous movement of the polishing belt polishes the parts. Since the polishing belt will wear down over time, affecting the polishing effect, the tension adjustment component 4 can be used to adjust the polishing belt to a suitable tension. The directional handle 44 is slid to a suitable height and locked in place using the positioning pin 43. The movement of the directional handle 44 will drive the tension rod 46 and the tension wheel 49 to move. The tension wheel 49 presses against the polishing belt, thereby adjusting the polishing belt to a suitable tension state. To further enhance the accuracy of the tension wheel 49, the rocker arm 48 can be rotated, causing the lead screw 47 to rotate, which in turn drives the tension rod 46 and the tension wheel 49 to move, thereby fine-tuning the position of the tension wheel 49. This helps to enhance the accuracy of the tension wheel 49 pressing down on the polishing belt, making it easier to adjust the polishing belt to a more precise tension level, which helps to ensure the polishing effect.

[0024] Example 2

[0025] Based on Example 1, such as Figure 1 and Figure 3As shown, it also includes a calibration mechanism 5, which includes a connecting plate 51. The tension adjustment assembly 4 is connected to the connecting plate 51. The connecting plate 51 is connected to the tension adjustment assembly 4 by two first bolts 52. The connecting plate 51 is connected to a connecting pipe 53, which is made of rigid material. The front side of the connecting pipe 53 is connected to a calibration plate 54. The front and rear parts of the calibration plate 54 are rotatably connected to centering wheels 55, and the centering wheels 55 are slidably connected to the polishing belt.

[0026] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a shock-absorbing mechanism 6, which includes a first pressure plate 61. The first pressure plate 61 is connected to both the upper and lower sides of the front of the drive shaft. The second pressure plate 64 is connected to both the upper and lower sides of the front of the drive wheel by a second bolt 65. The second pressure plate 64 is also connected to both the upper and lower sides of the front of the driven wheel by a second bolt 65. A damper 62 is connected between the second pressure plate 64 and the adjacent first pressure plate 61. A spring 63 is connected inside the damper 62. The first pressure plate 61 and the second pressure plate 64 can buffer and dampen the drive shaft, drive wheel, and driven wheel.

[0027] It should be noted that, in order to prevent the polishing belt from shifting from the predetermined positions of the driving and driven wheels after long-term operation, the polishing belt can be centered by the calibration mechanism 5. During the movement of the tension rod 46, the connecting plate 51, connecting pipe 53 and calibration plate 54 will move successively. By fixing the position of the centering wheel 55, the centering wheel 55 limits the polishing belt, so that the polishing belt will be in the centered moving position. Since the driving wheel, driven wheel and transmission shaft will vibrate during the movement, this vibration will limit the stability of the polishing assembly 3 during operation. The damper 62 and spring 63 can be used to dampen the vibration of the adjacent first pressure plate 61 and second pressure plate 64, thereby enhancing the overall stability of the device.

[0028] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
