Description

Technical Field

[0001] This utility model belongs to the field of grinding machine technology, and specifically relates to a grinding disc oscillation mechanism for a double-end vertical grinding machine. Background Technology

[0002] In the machining process of a double-end vertical grinder, oscillating feeding is a commonly used feeding method. It involves placing the workpiece in an oscillating grinding disc (clamp) and allowing it to pass through the grinding wheel in an arc-shaped trajectory, thus achieving double-end grinding of the workpiece. This feeding method is widely used in workpiece machining scenarios where a large machining surface is required due to its large machining surface area and high precision.

[0003] However, the grinding disc oscillation mechanism in existing double-end vertical grinders has a problem with its height being unadjustable. Since different grinder models may have different grinding head heights, existing oscillating feeding mechanisms cannot adapt to different grinder models. In practical applications, if the height of the grinding head does not match the height of the oscillation mechanism, the workpiece cannot enter the grinding zone correctly, thus affecting the grinding effect and machining quality.

[0004] To address this issue, the current common practice is to customize the oscillating feeding mechanism on a one-to-one basis, meaning the oscillating mechanism is tailored to the specific height of each grinding machine. However, this approach not only increases production costs but also reduces production efficiency. Each time a grinding machine is changed or the grinding head height is adjusted, the oscillating mechanism needs to be re-customized, which wastes time and resources and increases the company's operating costs.

[0005] Therefore, designing a grinding disc oscillation mechanism for a double-end vertical grinding machine with adjustable height is of significant practical importance and market demand. Summary of the Invention

[0006] To address the shortcomings of the existing technology, this utility model provides a grinding disc oscillation mechanism for a double-end vertical grinder to solve the aforementioned problems.

[0008] Furthermore, an adjusting arm is horizontally arranged on the grinding disc, and a gearbox with an open bottom is provided at the end of the adjusting arm. An adjusting shaft is passed through the top of the gearbox, and a small gear is provided at the bottom of the adjusting shaft. Two large gears that mesh with the small gear are rotatably arranged on the top of the inner wall of the gearbox. The bottom of the two large gears are respectively coaxially provided with screws that are screwed to the end of the rocker arm. Two guide pins are vertically arranged on the top of the inner wall of the gearbox. The end of the rocker arm is provided with pin holes that correspond one-to-one with the guide pins. A turntable is provided at the top of the adjusting shaft, and a scale plate surrounding the turntable is provided on the gearbox.

[0009] Furthermore, a handle insertion hole is provided at the top axis of the turntable.

The overall structure is compact, easy to operate, and effectively improves the efficiency and precision of grinding processes. Attached Figure Description

[0020] To better understand this utility model, the following is in conjunction with... Figures 1 to 4 The embodiments of this utility model will be explained in detail below.

[0021] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all relative to the direction of the text. Figure 1 The directions are based on "front, back, left, right, up, down".

[0022] This utility model discloses a grinding disc oscillation mechanism for a double-end vertical grinder, comprising a housing 1 with an open top, designed to provide stable support and installation space. A sliding cover 2 is provided on the top of the housing 1, connected to the housing 1 via a telescopic part 3. This telescopic part 3 can be a cylinder, hydraulic cylinder, or electric push rod, etc., and its main function is to adjust the height of the cover 2, thereby adjusting the height of the entire oscillation mechanism.

[0023] Inside the cover 2, there is a horizontal plate 4, on which a rotating shaft 5 extends out of the cover 2 and is vertically mounted. At the top of the rotating shaft 5, a horizontal rocker arm 6 is connected, and at the end of the rocker arm 6, a grinding disc 7 for clamping the workpiece is mounted. Thus, when the rotating shaft 5 rotates, the rocker arm 6 and the grinding disc 7 will swing accordingly, feeding the workpiece into the grinding area.

[0024] To achieve the rotation of the rotating shaft 5, an eccentric gear 8 is horizontally mounted on the cross plate 4. A first connecting rod 9 is hinged to the eccentric gear 8, and a second connecting rod 10 is hinged to the end of the first connecting rod 9. The second connecting rod 10 is fixedly connected to the rotating shaft 5. In this way, when the eccentric gear 8 rotates, the rotating shaft 5 and the rocker arm 6 can swing through the transmission of the connecting rod.

[0025] To drive the rotation of the eccentric gear 8, a transmission shaft 11 is vertically threaded through the horizontal plate 4. A transmission gear 12, meshing with the eccentric gear 8, is located at the top of the transmission shaft 11. The bottom end of the transmission shaft 11 is designed as a splined shaft. A bushing 13, fitted onto the splined shaft, is housed inside the housing 1, and a drive unit 14 drives the bushing 13 to rotate. Thus, when the drive unit 14 is operating, the rotation of the eccentric gear 8 can be driven through the transmission shaft 11 and the transmission gear 12. Figure 1 As shown, the drive unit 14 is preferably a motor, which is driven by a gear transmission to drive the bushing 13 and its splined shaft to rotate synchronously.

[0026] To further improve the applicability of the present invention, an adjusting arm 15 is provided on the grinding disc 7, and the end of the adjusting arm 15 is connected to a gearbox 16 with an open bottom. An adjusting shaft 17 is passed through the top of the gearbox 16, and a small gear 18 is provided at the bottom end of the adjusting shaft 17. Two large gears 19 are rotatably provided on the top of the inner wall of the gearbox 16, each meshing with the small gear 18. A screw 20 is coaxially provided at the bottom of each of the two large gears 19, which is screwed to the end of the rocker arm 6. In this way, when the adjusting shaft 17 is rotated, the position of the screw 20 at the end of the rocker arm 6 can be adjusted through the transmission of the small gear 18 and the large gears 19, thereby changing the height of the grinding disc 7.

[0027] For easy adjustment, a turntable 22 is provided at the top of the adjusting shaft 17, and a scale 23 surrounding the turntable 22 is provided on the gearbox 16. In this way, the height of the grinding disc 7 can be precisely adjusted by observing the scale 23. In addition, to facilitate the rotation of the turntable 22, a handle insertion hole 24 is provided at the top axis of the turntable 22, and a handle can be inserted to rotate the turntable 22.

[0028] To improve the stability of the entire swing mechanism, several adjustable feet 25 are installed at the bottom of the housing 1, allowing for adjustment of the housing 1's level as needed. Simultaneously, to increase the weight of the entire swing mechanism and thus enhance stability, a counterweight water tank 26 is installed inside the housing 1. When the swing mechanism needs to be moved, water can be released to reduce its weight; and after the position is confirmed, water can be added to further secure the swing mechanism and prevent it from shaking during processing.

[0029] To reduce friction and wear during transmission, a bearing 28 is installed between the transmission shaft 11 and the horizontal plate 4. Meanwhile, to fix components such as the eccentric gear 8, the rotating shaft 5, and the bushing 13, corresponding bearing seats 30 are installed on the horizontal plate 4.

[0030] The usage and principle of this utility model:

[0031] In use, first, adjust the height of the cover 2 and the swing mechanism via the telescopic part 3 according to the height of the grinding head, so that the swing trajectory of the grinding disc 7 matches the grinding area. Then, adjust the height of the grinding disc 7 as needed, precisely by rotating the turntable 22 and observing the scale 23. Next, after confirming that the position of the swing mechanism is stable, add water to the counterweight water tank 26 to increase stability. Finally, start the drive unit 14, which drives the rotating shaft 5 and the rocker arm 6 to swing through the transmission shaft 11, transmission gear 12 and eccentric gear 8, sending the workpiece into the grinding area for processing. After processing is completed, turn off the drive unit 14, remove the workpiece, and proceed to the next round of processing. When it is necessary to move the swing mechanism, first release water from the counterweight water tank 26 to reduce its weight before moving it.
