Problems solved by technology

[0004] However, superhard functional ceramics are typical hard and brittle materials, which are difficult to process, have low material removal efficiency, and the service life of processing tools is not long. It is difficult to effectively suppress microscopic cracks, deterioration, damage and other defects on the device surface. The yield and The use performance cannot be effectively guaranteed, and the existing grinding machine tools are not enough to process curved workpieces that meet the requirements, so the improvement of the grinding machine needs to be solved urgently

Embodiment 1

[0033] Such as figure 1 , figure 2 As shown, the superhard material curved surface grinding and polishing processing device includes a first feed shaft 3, a second feed shaft 2, a first rotary shaft 1, a second rotary shaft 4, a third rotary shaft 5, a tool 7, and a workpiece holder holding device 6 and connecting plate 19; wherein, one end of the first rotary shaft 1 is coaxially connected with a cutter 7, and the cutter 7 is a grinding wheel, and the first rotary shaft 1 is slidingly connected with the second feed shaft 2, and by driving the second feed Shaft 2 enables the first rotary shaft 1 to reciprocate axially along the second feed shaft 2; the first feed shaft 3 is arranged perpendicular to the axis of the second feed shaft 2; Sliding connection, by driving the first feed shaft 3 to make the second rotary shaft 4 reciprocate axially along the first feed shaft 3; the third rotary shaft 5 is perpendicular to the axis of the second rotary shaft 4 and connected through ...

Embodiment 2

[0036] On the basis of Embodiment 1, the workpiece clamping device 6 is set as a vacuum gripper system, and a cooling liquid device is set near the tool 7 .

[0037] The vacuum gripper system facilitates the disassembly and clamping of the workpiece 8 to be processed, and the cooling liquid device realizes the cooling of the tool 7 and the contact point with the tool 7 .

Embodiment 3

[0039] On the basis of Embodiment 1, the workpiece clamping device 6 is connected to one end of the first rotary shaft 1 , and the tool 7 is connected to one end of the third rotary shaft 5 .

[0040] This solution is suitable for vertical machine tools. At this time, the first rotary shaft 1 should be driven at a low speed when it is working, and the third rotary shaft 5 should be driven at a high speed when it is working.

Abstract

The invention discloses a super-hard material curved surface grinding and polishing machining device, and the problem that a traditional grinding machine cannot better grind a curved-surface workpieceis solved. The device comprises a first feeding shaft, a second feeding shaft, a first rotating shaft, a second rotating shaft, a third rotating shaft, a cutter and a workpiece clamping device. The first feeding shaft is connected with the second rotating shaft in a sliding mode, the second rotating shaft is connected with the third rotating shaft, one end of the third rotating shaft is connectedwith the workpiece clamping device, the axis of the first feeding shaft is perpendicular to that of the second feeding shaft, the first rotating shaft is connected to the second feeding shaft in a sliding mode, and one end of the first rotating shaft is connected with the cutter. The super-hard material curved surface grinding and polishing machining device has the advantages of being capable ofmachining spherical or aspheric curved surfaces and concave curved surfaces, being high in machining precision and good in surface quality and the like.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a grinding and polishing device for superhard material curved surfaces. Background technique [0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oil stones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machine tools, abrasive belt grinders, grinding machines and polishing machine etc. [0003] With the increase in the number of high-precision and high-hardness mechanical parts, as well as the development of precision casting and precision forging processes, the performance, variety and output of grinding machines are constantly improving and increasing; common grinding machines include cylindrical grinding machines and internal grinding machines. , surface grinder,...
