The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] like Figure 1-5 As shown, the utility model is a multi-station industrial tool grinder, including a workbench, on which are arranged a material loading and unloading device 1, a dividing and rotating material transporting device 2, a tool support assembly 3 and a plurality of grinding mechanisms 4, the plurality of grinding mechanisms 4 are adjacently arranged around the dividing and rotating material transporting device 2, the dividing and rotating material transporting device 2 includes a plurality of grinding fixtures 5, the number of the grinding fixtures 5 is the same as that of the tool support assembly 3, the tool support assembly 3 can support the tool on the grinding fixture 5, a plurality of grinding stations cooperate with a plurality of grinding mechanisms 4 one by one, and the plurality of grinding mechanisms 4 can grind the tool in different processes.

[0026] Through the setting of multiple stations, the grinding tools that need to go through multiple grinding processes can be distributed to multiple grinding mechanisms 4. Each grinding mechanism 4 implements different grinding processes, thereby improving the grinding efficiency and avoiding the traditional situation of repeatedly replacing the grinding wheel, thereby realizing fully automated grinding processing.

[0027] The indexing and rotating material transporting device 2 further comprises an indexing turntable mechanism, a material rotating mechanism and a lifting and lowering driving mechanism. The moving end of the material rotating mechanism is fixedly connected to the grinding fixture 5 .

[0028] By setting the material rotating mechanism, the material on the grinding fixture 5 can be rotated, and each surface of the tool can be accurately ground.

[0029] By setting the indexing turntable mechanism, the grinding fixture 5 can be driven to perform indexing rotation to cooperate with the next grinding mechanism 4 to perform grinding.

[0030] By setting the lifting drive mechanism, the grinding fixture 5 can be driven to perform lifting movement, and the tool on the grinding fixture 5 can be placed on the tool holder assembly 3.

[0031] The number of the grinding mechanisms 4 is three, the number of the grinding fixtures 5 is four, and the three grinding mechanisms 4 and the material loading and unloading devices 1 are matched with the four grinding fixtures 5 one by one respectively.

[0032] By setting four groups of grinding fixtures 5, three groups of grinding mechanisms 4 and material loading and unloading devices 1 are respectively arranged in front, behind, left and right of the indexing and rotating material conveying device 2, ensuring that the three groups of grinding mechanisms 4 and the grinding mechanisms 4 and material loading and unloading devices 1 do not interfere with each other.

[0033] The grinding mechanism 4 includes a main mounting frame 41, a multi-axis driving module, a grinding assembly and a force unloading mechanism. The multi-axis driving module includes a Z-axis lifting module 43. The grinding assembly is fixedly connected to the moving end of the Z-axis lifting module 43. The force unloading mechanism is fixedly arranged on the Z-axis lifting module 43, and the force unloading mechanism is arranged above the grinding assembly. The lower end of the force unloading mechanism is fixedly connected to the grinding assembly.

[0034] By setting the Z-axis lifting module 43, the grinding assembly can be effectively driven to move up and down.

[0035] The force unloading mechanism comprises a force unloading mounting frame 421 and a force unloading elastic member, and the upper end of the force unloading elastic member is fixedly arranged on the force unloading mounting frame 421 .

[0036] There are two unloading spring members, and the pulling force of the unloading mechanism can be further increased by using the two unloading spring members. The unloading force is larger, and the pressure of the grinding assembly on the Z-axis lifting module 43 is further reduced.

[0037] The force-releasing spring member is a constant-force magnetic spring 422 .

[0038] By setting the constant force magnetic spring 422, a constant upward pulling force can be provided during the movement of the grinding component, thereby achieving effective force unloading, effectively reducing the load of the Z-axis lifting module 43, and preventing the Z-axis lifting module 43 from lifting and lowering under high load for a long time, which affects the service life of the components.

[0076] First, the material is loaded from the material loading and unloading device 1, and the grinding fixture 5 clamps it, and the tool is moved to different grinding mechanisms 4 in turn to perform different processing steps.

[0077] The three grinding mechanisms 4 grind the tools in different processes at the same time, and process the three tools in different processes respectively at the same time. Compared with the traditional integrated system, the grinding wheel is frequently replaced, and the grinding efficiency is higher.

[0078] During the grinding process, the lifting drive mechanism controls the grinding fixture 5 to rotate, and then descends to place the tool on the tool holder to continue grinding, thereby ensuring the flexibility of grinding.

[0079] After the grinding is completed by the multiple grinding mechanisms 4, the material is unloaded through the material loading and unloading device 1, and the grinding is completed.

[0080] From the above, it can be seen that the beneficial effect of the utility model is: adopting its mechanism can effectively solve the problem of low working efficiency of the grinder in the prior art due to only having one working head. After completing one process, the next process needs to select a grinding wheel from the grinding wheel library for replacement processing, which has the problem of low grinding efficiency. By using this product structure, multiple grinding mechanisms 4 cooperate with the indexing and continuous material transport device, and can continuously process multiple tools in different processes, effectively improving the grinding efficiency, and can effectively avoid the single working head, and the need for frequent replacement of the single head for processing, thereby ensuring the grinding precision requirements, which is conducive to improving the competitiveness of the enterprise.
