Description

A four-sided grinding head for a multifunctional five-axis machine tool

technical field

The utility model relates to the technical field of mobile phone shell surface grinding and polishing, in particular to a four-sided grinding head for a multifunctional five-axis machine tool.

Background technique

At present, there are two kinds of grinding heads on the market: pneumatic grinding heads and electric grinding heads. The pneumatic grinding heads are driven by compressed air, and the electric grinding heads are driven by motors. The surface of the shell is physically ground and polished. As shown in Figure 1, the electric grinding head in the prior art is installed on a five-axis manipulator, which includes four motors 1 and four grinding sheets 3, each motor 1 correspondingly drives a grinding sheet 3 The mobile phone case 4 is polished by rotation, and the grinding sheet 3 is on the same plane, and the grinding head is rotated by another motor 2, but the disadvantage of the electric grinding head with this structure is that multiple motors need to be installed in the grinding head , The motor speed is high during grinding, but the cable of the motor restricts the grinding head from being able to rotate continuously at 360 degrees. The price of the grinding head is expensive, and because the grinding piece is a single independent rotation, the grinding area of the grinding piece is small during grinding, so the grinding piece will be consumed very quickly. The grinding sheet needs to be replaced again, and the grinding efficiency is very low.

Another type of pneumatic grinding head is generally used on a six-axis robot, but the six-axis robot has poor rigidity and can only make one product at a time. The head is very difficult to do. Moreover, the disadvantages of the pneumatic grinding head are high energy consumption and high noise, and it can be used by hand or mounted on a six-axis robot or five-axis grinding machine.

2. The grinding plate of the present invention rotates on the rectangular frame through two sets of driving devices. The driving device includes a rotating shaft, a driving bevel gear, a driven bevel gear and a running wheel. There are four driven bevel gears. And corresponding to the four rotating wheels, the driving bevel gear rotates under the drive of the rotating shaft, and the driven bevel gear is meshed with the driving bevel gear, that is, the driving bevel gear can drive the four driven bevel gears to rotate, thus Drive the rotating wheels to rotate respectively, and the rotating wheels can respectively drive the grinding plate to rotate. The driving mode of the grinding plate and the two rotating wheels is a four-link movement structure. The four-sided grinding plate of the utility model is driven by a conical gear mechanism, and the four-sided grinding plate The two rotate in opposite directions to ensure the balance of the torque, thereby offsetting the vibration caused by the unbalanced force. Therefore, the utility model does not need to be equipped with a motor to drive the grinding plate to rotate, which greatly reduces the processing cost.

3. The utility model uses a rectangular grinding plate to grind the mobile phone case. Since the grinding plate rotates, the whole grinding plate is used to polish the mobile phone case. The grinding area that can be used for grinding is large and will not be concentrated in Grinding at one point greatly prolongs the replacement time of the grinding plate, makes the grinding plate more wear-resistant, does not need to replace the grinding plate frequently, and greatly improves the processing efficiency.

4. The utility model is provided with a driven wheel in the middle of the rectangular frame body, and the driven wheel is rotatably installed on the rectangular frame body and connected with the grinding plate, thereby improving the rigidity of the grinding plate during grinding.
