Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically a stable and high-precision polishing device. Background Technology

[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical methods to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface.

[0003] In existing polishing machines, the polishing wheel is connected to a motor at one end. For example, a polishing machine with publication number CN111890209B includes a frame, a polishing wheel mechanism, and a working platform. The polishing wheel mechanism includes a lifting structure fixed to the frame, on which a polishing wheel assembly is fixed, and the lifting structure drives the polishing wheel assembly to move up and down. The polishing wheel assembly includes a connecting plate, on which a guide post is arranged laterally. Both ends of the guide post are fixed to the connecting plate, and a sliding plate is slidably connected to the middle of the guide post. A first driving assembly is connected to the sliding plate to drive its sliding. The first driving assembly is fixed to the connecting plate, and a first motor is fixed to the end face of the sliding plate away from the guide post. The polishing wheel is connected to the output shaft of the first motor.

[0004] As can be seen from the attached diagram of the above scheme, one end of the polishing wheel is connected to the output shaft of the first motor, and the other end is suspended. Since the motor will vibrate when it is working, the polishing wheel will also vibrate. When the polishing wheel polishes the surface of the workpiece, the vibration will affect the polishing accuracy, resulting in poor polishing effect. Furthermore, when the workpiece to be polished is wide, a longer polishing wheel is required. The longer polishing wheel will vibrate more during use, which will make it impossible to perform the polishing work.

[0005] Therefore, it is necessary to optimize the structure of existing polishing machines. Utility Model Content

[0006] This utility model discloses a stable and high-precision polishing device to solve the technical problem of vibration affecting precision.

[0007] To solve the above-mentioned technical problems, the present invention proposes the following optimized technical solution: A stable and high-precision polishing device includes a frame, a polishing wheel mounted on the frame, an auxiliary wheel rotatably mounted on the frame, and a drive assembly for driving the polishing wheel to rotate. The polishing wheel and the auxiliary wheel are arranged vertically opposite each other. The frame has an inverted U-shaped single-sided hanger. The drive assembly is located at one end of the single-sided hanger. The output shaft of the drive assembly is connected to one end of the polishing wheel, and the other end of the polishing wheel is rotatably connected to the other end of the single-sided hanger.

[0008] Furthermore, the frame is provided with two connecting ears which are oppositely arranged, and both ends of the auxiliary wheel are respectively connected to the two connecting ears through bearings.

[0009] Furthermore, the driving component includes a first motor, a speed reducer and a transmission belt. The first motor and the speed reducer are both fixed on the frame. The transmission belt is sleeved on the output shaft of the first motor and the input shaft of the speed reducer, and the output shaft of the speed reducer is connected to one end of the polishing wheel.

[0010] Furthermore, it further includes a lifting component which is arranged on the frame and is used to drive the polishing wheel to lift.

[0011] Furthermore, the lifting component includes a second motor, a丝杆 (it should be "screw rod" in English) and a lifting plate. The second motor is fixed on the frame. The screw rod is connected to the output shaft of the second motor. The lifting plate is connected to the screw rod through a screw rod seat. The driving component, the single-sided hanger and the polishing wheel are all arranged on the lifting plate.

[0012] Furthermore, the numbers of the driving component, the polishing wheel, the auxiliary wheel and the single-sided hanger are all set to two groups. The first group of the driving component, the polishing wheel, the auxiliary wheel and the single-sided hanger are used to polish one side of the workpiece, and the second group of the driving component, the polishing wheel, the auxiliary wheel and the single-sided hanger are used to polish the other side of the workpiece.

[0013] Furthermore, the first group of polishing wheels are located above the auxiliary wheels and are used to polish the upper surface of the workpiece; the second group of polishing wheels are located below the auxiliary wheels and are used to polish the lower surface of the workpiece.

[0014] The utility model has the following beneficial effects compared with the prior art: The utility model is provided with an inverted "U"-shaped single-sided hanger. Both ends of the polishing wheel are respectively connected to the driving component and one end of the single-sided hanger. Since the other end of the polishing wheel is connected to the single-sided hanger, the single-sided hanger has a supporting effect on the polishing wheel. Compared with the setting where one end of the polishing wheel is suspended, the polishing wheel is more stable during operation, so that the polishing accuracy is higher and the polishing effect is better.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] See Figures 1-4 A stable and high-precision polishing device includes a frame 1, a polishing wheel 2 mounted on the frame 1, an auxiliary wheel 3 rotatably mounted on the frame 1, and a drive assembly for driving the polishing wheel 2 to rotate. The polishing wheel 2 and the auxiliary wheel 3 are arranged vertically opposite each other. The frame 1 is provided with an inverted "U"-shaped single-sided hanger 4. The drive assembly is located at one end of the single-sided hanger 4. The output shaft of the drive assembly is connected to one end of the polishing wheel 2, and the other end of the polishing wheel 2 is rotatably connected to the other end of the single-sided hanger 4.

[0022] Since one end of the polishing wheel 2 is connected to the drive assembly, when the drive assembly drives the polishing wheel 2 to rotate, the vibration of the drive assembly is also transmitted to the polishing wheel 2. Since the other end of the polishing wheel 2 is connected to the single-sided hanger 4, the single-sided hanger 4 has a stabilizing effect on the polishing wheel 2, which can greatly reduce the vibration of the polishing wheel 2, thereby making the polishing wheel 2 more precise and ensuring the stability of the polishing wheel 2 over a longer period of time.

[0023] In this embodiment, the frame 1 is provided with two connecting ears positioned opposite each other, and the two ends of the auxiliary wheel 3 are respectively connected to the two connecting ears by bearings. When the workpiece is clamped between the auxiliary wheel 3 and the polishing wheel 2, the polishing wheel 2 rotates to drive the workpiece to move, and the movement of the workpiece can drive the auxiliary wheel 3 to rotate. Therefore, the rotating arrangement of the auxiliary wheel 3 facilitates the movement of the workpiece.

[0024] In this embodiment, the drive assembly includes a first motor 5, a reducer 6, and a transmission belt. The first motor 5 and the reducer 6 are both fixed on the frame 1. The transmission belt is sleeved on the output shaft of the first motor 5 and the input shaft of the reducer 6. The output shaft of the reducer 6 is connected to one end of the polishing wheel 2.

[0025] In this embodiment, a lifting assembly is also included. The lifting assembly is disposed on the frame 1 and is used to drive the polishing wheel 2 to move up or down so that the polishing wheel 2 moves closer to or further away from the auxiliary wheel 3, thereby adjusting the distance between the polishing wheel 2 and the auxiliary wheel 3 to match workpieces of different thicknesses.

[0026] In this embodiment, the lifting assembly includes a second motor 7, a lead screw 8, and a lifting plate 9. The second motor 7 is fixed on the frame 1. The lead screw 8 is connected to the output shaft of the second motor 7. The lifting plate 9 is connected to the lead screw 8 via a lead screw 8 seat. The drive assembly, the single-sided hanger 4, and the polishing wheel 2 are all disposed on the lifting plate 9. Specifically, the drive assembly and the single-sided hanger 4 are fixed on the lifting plate 9, and one end of the polishing wheel 2 is connected to the drive assembly and the other end is connected to the single-sided hanger 4.

[0027] In this embodiment, the number of the driving assembly, the polishing wheel 2, the auxiliary wheel 3, and the single-sided hanger 4 are all set in two groups. The first group of the driving assembly, polishing wheel 2, auxiliary wheel 3, and single-sided hanger 4 is used to polish one side of the workpiece, and the second group of the driving assembly, polishing wheel 2, auxiliary wheel 3, and single-sided hanger 4 is used to polish the other side of the workpiece. That is, the workpiece passes through the first group and the second group of polishing structures in sequence. The workpiece first passes through the gap between the polishing wheel 2 and the auxiliary wheel 3 in the first group, and then passes through the gap between the polishing wheel 2 and the auxiliary wheel 3 in the second group. When the first group and the second group are working, only the polishing wheel 2 vibrates, and the auxiliary wheel 3 does not vibrate, thereby ensuring higher polishing accuracy. Most existing polishing machines use two polishing wheels 2, one above the other, with the workpiece passing between them. When the two polishing wheels 2 polish the workpiece simultaneously, the vibration is greater, resulting in low accuracy and poor polishing effect. This application uses two sets of staggered polishing structures, which greatly reduces vibration when polishing the top or bottom of the workpiece, thereby greatly improving accuracy.

[0028] In this embodiment, the first set of polishing wheels 2 is located above the auxiliary wheel 3 and is used to polish the upper surface of the workpiece; the second set of polishing wheels 2 is located below the auxiliary wheel 3 and is used to polish the lower surface of the workpiece. That is, the staggered arrangement of the polishing wheels on both the upper and lower surfaces significantly reduces vibration compared to polishing both surfaces simultaneously, thereby greatly improving accuracy.

[0029] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
