Description

Technical Field

[0001] This utility model relates to the field of grinding machines, and in particular to an automatic calibration mechanism for a double-end grinding machine. Background Technology

[0002] A grinding machine is a machine tool that uses abrasives to grind workpieces to obtain the desired shape, size, and precision machined surface. The function of a grinding machine is to perform highly precise grinding with very small surface roughness. It can perform high-efficiency grinding. There are many types of grinding machines, and the double-end grinding machine is one of them.

[0003] A double-end face grinder is a machine tool used to grind both ends of a circular workpiece simultaneously. During the processing of a double-end face grinder, it is necessary to calibrate the grinding position of the circular workpiece so that it is at the same horizontal height as the grinding wheel. However, currently, the grinding position calibration of the circular workpiece requires manual rotation of the throttle for adjustment. Each calibration requires multiple rotations for fine adjustment, resulting in a lengthy and cumbersome operation process and reducing the calibration speed of the grinding position of the circular workpiece. To address this issue, we propose an automatic calibration mechanism for double-end face grinders. Utility Model Content

[0004] The purpose of this invention is to provide an automatic calibration mechanism for a double-end face grinder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic calibration mechanism for a double-end face grinder includes a machining table. Two grinder bodies are mounted on the upper surface of the machining table. An adjustment platform is located above the machining table. Two fixing components are located on the outside of the adjustment platform. A drive cover is fixedly mounted on the bottom surface of the machining table. A servo motor is fixedly mounted on the bottom surface of the drive cover. A transmission screw is mounted on the output end of the servo motor. A transmission screw plate is threadedly connected to the outer surface of the transmission screw. An adjustment plate is connected to the outer surface of the transmission screw plate. The upper surface of the adjustment plate is connected to the bottom surface of the adjustment platform. A support plate is connected to the outer surface of the machining table. A controller is mounted on the outer surface of the support plate.

[0007] In a further embodiment, each of the two fixing members includes a fixing plate fixedly installed on one side of the adjustment platform, a fixing cover fixedly installed on the side of the two fixing plates that are far apart from each other, a cylinder fixedly installed on the inner sidewall of each of the two fixing covers, and a sliding plate fixedly installed on the telescopic end of each of the two cylinders.

[0008] In a further embodiment, a fixing clamp is fixedly installed on one side of each of the two sliding plates that are close to each other, and a sliding hole is opened on one side of each of the two fixing plates that are close to each other. The outer surfaces of the two sliding plates are slidably connected to the inner walls of the two sliding holes respectively.

[0009] In a further embodiment, an arc-shaped groove is formed on the upper surface of the adjustment platform, and a circular workpiece is placed on the inner bottom wall of the arc-shaped groove.

[0010] In a further embodiment, the inner wall of the drive cover has two limiting holes, and the inner walls of the two limiting holes are slidably connected to limiting blocks. The sides of the two limiting blocks that are close to each other are connected to the outer surface of the adjustment plate.

[0011] In a further embodiment, a rectangular opening is provided on the upper surface of the processing table, the inner wall of the rectangular opening is slidably connected to the outer surface of the adjustment plate, a bearing ring is embedded in the inner bottom wall of the drive cover, and the outer surface of the transmission screw is connected to the inner ring of the bearing ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the operation of the servo motor under the drive cover, can precisely drive the transmission screw to rotate. In addition, with the help of the transmission screw plate, it can drive the adjustment plate to perform precise transmission, and drive the adjustment table and the circular workpiece to slowly adjust their height. The circular workpiece can be stably adjusted to the same level as the grinding wheel, which improves the calibration speed of the grinding position of the circular workpiece. Then, with this mechanism, the operator only needs to place the circular workpiece on the adjustment table, fix it with the fixing parts, and start the servo motor to quickly complete the lifting and lowering calibration of the adjustment table without repeated manual adjustment, which will make the calibration process much simpler.

Each grinder body 2 has an electrically driven base, enabling grinding of the workpiece through movement of the grinder body 2. This is a conventional grinder structure. An adjustment table 3 is located above the processing table 1, and two fixing parts 5 are located on the outside of the adjustment table 3. A drive cover 8 is fixedly mounted on the bottom surface of the processing table 1, and a servo motor 801 is fixedly mounted on the bottom surface of the drive cover 8. A transmission screw 803 is mounted on the output end of the servo motor 801, and a transmission screw plate 804 is threadedly connected to the outer surface of the transmission screw 803. The outer surface of the transmission screw plate 804 is connected to... An adjustment plate 7 is connected, with its upper surface connected to the bottom surface of the adjustment table 3. A support plate 12 is connected to the outer surface of the processing table 1, and a controller 13 is installed on the outer surface of the support plate 12. The processing table 1 can support the entire mechanism and the two grinding machine bodies 2. The two grinding machine bodies 2 can perform double-end grinding.

The controller 13 is used to control the operation of the servo motor 801 and other components, realizing the automated control of the calibration process.

[0023] In a further embodiment, each of the two fixing members 5 includes a fixing plate 501 fixedly installed on one side of the adjusting table 3. A fixing cover 502 is fixedly installed on the side of the two fixing plates 501 that are far apart from each other. A cylinder 503 is fixedly installed on the inner side wall of each of the two fixing covers 502. The cylinder 503 can be connected to an external air source device. A sliding plate 506 is fixedly installed on the telescopic end of each of the two cylinders 503. A fixing clamp 505 is fixedly installed on the side of the two sliding plates 506 that are close to each other. A sliding hole 504 is opened on the side of the two fixing plates 501 that are close to each other. The outer surface of the two sliding plates 506 is slidably connected to the inner wall of the two sliding holes 504 respectively. The fixing plate 501 serves to support the fixing cover 502. The telescopic end of the cylinder 503 drives the sliding plate 506 and the fixing clamp 505 to slide, thereby clamping and fixing the circular workpiece 4 placed on the adjusting table 3, preventing the circular workpiece 4 from shifting during grinding and calibration, and ensuring processing accuracy and operational safety.

[0024] In a further embodiment, the upper surface of the adjusting table 3 is provided with an arc-shaped groove 11, and a circular workpiece 4 is placed on the inner bottom wall of the arc-shaped groove 11. The inner wall of the drive cover 8 is provided with two limiting holes 10, and the inner walls of the two limiting holes 10 are slidably connected with limiting blocks 9. The sides of the two limiting blocks 9 that are close to each other are connected to the outer surface of the adjusting plate 7. The upper surface of the processing table 1 is provided with a rectangular opening 6, and the inner wall of the rectangular opening 6 is slidably connected to the outer surface of the adjusting plate 7. The inner bottom wall of the drive cover 8 is inlaid with a bearing ring 802, and the outer surface of the transmission screw 803 is connected to the inner ring of the bearing ring 802. The arc-shaped groove 11 can be used to place the circular workpiece 4. Through the sliding cooperation between the rectangular opening 6 and the adjusting plate 7, and the cooperation between the limiting holes 10 and the limiting blocks 9 on the inner wall of the drive cover 8, the movement of the adjusting plate 7 can be guided and limited, ensuring that the adjusting table 3 rises and falls smoothly. The bearing ring 802 will make the transmission screw 803 rotate stably.

[0025] The working principle of this utility model is as follows: First, the circular workpiece 4 is placed above the arc groove 11. At this time, the two fixing parts 5 are activated to clamp and fix the circular workpiece 4 from both sides, so that the circular workpiece 4 will not be displaced during the subsequent calibration process. Then, the servo motor 801 is activated, which can drive the transmission screw 803 and the transmission screw plate 804 to perform threaded transmission. The transmission screw plate 804 will drive the adjustment table 3 to rise and fall smoothly through the adjustment plate 7. When the adjustment table 3 rises and falls, it will also drive the circular workpiece 4 to move up and down until the two ends of the circular workpiece 4 are at the same level as the grinding wheels of the two grinding machine bodies 2. Then, the grinding position of the circular workpiece 4 is quickly calibrated, which facilitates its grinding process.
