Description

Technical Field

[0001] The utility model relates to the technical field of polytetrafluoroethylene sealing component processing, in particular to a robot automatic material distributing and taking device. Background Art

[0002] PTFE sealing ring is a common sealing material, which is made of tetrafluoroethylene and has excellent chemical corrosion resistance, low friction coefficient and good high temperature resistance. PTFE sealing ring needs to be polished during the processing so that it can fit the workpiece better after actual installation. The existing polishing equipment has generally low polishing efficiency, and both material laying and material removal need to be done manually.

[0003] The Chinese patent with the authorization announcement number CN214603756U discloses a processing device for polytetrafluoroethylene seals, a processing device for polytetrafluoroethylene seals, comprising a base plate, the upper part of the base plate is fixedly connected to a support plate, the lower part of the support plate is fixedly connected to an electric telescopic rod, the lower end of the electric telescopic rod is fixedly connected to a grinding mechanism, the lower part of the support plate is provided with a discharging mechanism, the end of the bracket away from the electric telescopic rod is fixedly connected to a first rack, the inner side wall of the support plate is fixedly connected to a flat plate, the upper part of the base plate is fixedly connected to a guide frame through a support leg, and the upper end surface of the guide frame is fixedly connected to a placement cylinder. The utility model relates to the technical field of seal processing devices. The processing device for polytetrafluoroethylene seals solves the problem that the existing seal processing device needs to be repeatedly operated to clamp and replace the processed seals, which reduces the processing efficiency, and is inconvenient to grind the outer wall of the seal to improve the quality.

[0004] However, the device still has shortcomings: the device cannot grind the upper and lower surfaces of the seal, and the device needs to support the workpiece. If the seal is an O-shaped structure, if the support is too large, it is easy for its edge to be unable to be grinded. If the support is too small, the seal is easy to slide along the periphery of the support. Therefore, the scope of application of the device is relatively small. Utility Model Content

[0018] By setting a turntable that can be disassembled and replaced, it is possible to grind seals with different outer diameters. The seal is automatically moved to the processing point by moving the turntable. By setting grinding wheel A and grinding wheel B, the seal falls on grinding wheel A, so that grinding wheel B contacts the upper surface of the seal. Grinding wheel A and grinding wheel B rotate at high speed in opposite directions, thereby grinding the upper and lower surfaces of the seal at the same time.
