Description

Double station modular grinding and polishing machine

technical field

The patent of the present invention relates to a mechanical processing machine tool, and more specifically, to a dual-station modular grinding and polishing machine tool.

Background technique

For mass-produced parts or parts with complex shapes that need to be polished and polished, if manual polishing is used, the polishing quality cannot be guaranteed. At the same time, with the rising labor cost, the harm to the human body due to the harsh working environment must also be considered.

At present, grinding and polishing of castings can be carried out by grinding and polishing robots or special machine tools for grinding and polishing. The advantage of the grinding and polishing robot is that the grinding and polishing accuracy is high, and the disadvantage is that the teaching time of the grinding and polishing robot is long, and the investment cost of the enterprise is large. The special machine tool for grinding and polishing has the advantages of high efficiency, low cost, less one-time investment, and easy maintenance. With the continuous development of the social economy and the acceleration of the production rhythm of industrial products, it is urgent to design a high-efficiency casting grinding and polishing machine tool with double stations.

[CN 201520372094.5] A dual-station grinding and polishing integrated machine is invented, which realizes rough polishing and fine polishing, and improves the work efficiency of fixture polishing. However, this machine can only be used to polish and polish wooden furniture, and cannot be used to polish and polish metal castings.

[201610756990.0] invented a machine tool with a double-station worktable, including a base and a gantry mounted on the base. Two processing tables are used to process workpieces of different specifications. The feature of this invention is the use of a gantry frame, a set of driving power devices and two processing tables, and the structure is quite different from the structure proposed in this patent.

SUMMARY OF THE INVENTION

A grinding and polishing machine tool with double stations is designed, the same station is responsible for different grinding and polishing positions of the workpiece, and the two stations work in an assembly line, which significantly improves the grinding and polishing efficiency of castings. At the same time, the dual-station machine tool adopts a modular design, which can greatly shorten the manufacturing cycle of the machine tool and reduce maintenance costs.

A dual-station modular grinding and polishing machine tool comprises a bed module 1 , a left worktable module 2 , a right worktable module 3 , a left spindle module 4 , and a right spindle module 5 .

This double-station grinding and polishing machine tool adopts the modular design idea, and decomposes a machine tool that can complete complex grinding and polishing tasks into multiple sub-modules with independent functions, and each module cooperates with each other to complete all grinding and polishing needs. This design idea is based on two reasons, the expansion of machine tool functions and the quick maintenance and replacement of a certain module during use.

This double-station machine tool, its bed module includes two parts, a horizontal bed and a vertical bed, which can be cast as a whole by a unified casting method, or the horizontal bed and the vertical bed can be cast separately, and then Mechanical assembly. It is difficult to process with one-piece casting, but the stability of the bed is good; the horizontal bed and the vertical bed are cast separately, which can make processing convenient, and both have their own advantages and disadvantages.

This double-station machine tool is designed with a left worktable module and a right worktable module. The two modules share two horizontal guide rails. Both the left worktable module and the right worktable module can move along the horizontal guide rails. The purpose of this design is to It not only ensures that the worktable module has enough space for horizontal movement, but also enables the left and right worktable modules to share a horizontal guide rail, thereby increasing the stability of the grinding and polishing process, thereby improving the grinding and polishing quality. The left worktable module and the right worktable module are respectively equipped with rotary worktables, driven by the rotary motor, the castings that need to be polished can be rotated to a specified angle.

On the left and right sides of the vertical bed of this double-station machine tool, a left spindle module and a right spindle module are respectively installed. The left spindle module and the right spindle can move up and down along the vertical guide. The left horizontal movement motor and the left rotation motor in the left spindle module can respectively drive the grinding and polishing tool to move horizontally and rotate. In this way, the grinding and polishing tool itself has 3 degrees of freedom, and the casting to be polished and polished has 2 degrees of freedom. Therefore, each workpiece of this dual-station modular grinding and polishing machine is actually a 5-degree-of-freedom grinding and polishing unit, which can complete Grinding and polishing requirements for any complex parts.

In this double-station machine tool, the left spindle module and the right spindle module can be installed with grinding tools or polishing tools respectively according to the requirements of grinding or polishing, so as to complete the specified grinding or polishing tasks for castings.

Compared with the prior art, the advantage of the present invention is that the double-station, double-spindle machine tool can not only perform grinding or polishing operations on two castings at one time, but also can process or only process one casting in sequence according to the needs. Under the premise of meeting the rigidity requirements, the machine tool occupies a small area, reduces the cost and improves the processing efficiency. At the same time, in terms of the machine tool bed, according to the actual processing conditions, the horizontal bed and vertical bed can be cast as a whole by unified casting or can be cast separately, and then mechanically assembled.
