Description

Technical Field

[0001] The invention relates to the technical field of machine tool auxiliary equipment, and in particular to a waste chip cleaning device for a gear processing machine tool. Background Art

[0002] During the production process of gears, machine tools are usually used to process the gears. First, the gear blank is placed on the workbench of the machine tool. The spindle drives the tool to rotate, and the tool contacts the gear blank, thereby cutting the gear blank to form a gear product.

[0003] When cutting gear blanks, a large amount of waste chips will be generated. At the same time, the use of cutting fluid also increases the complexity of waste chip treatment. The traditional way of dealing with waste chips is to use an air gun to spray the inside of the machine tool after the gear processing is completed, so that the waste chips are blown to the bottom of the machine tool. Then, when the waste chips accumulate to a certain amount, the operator uses tools such as iron hooks or iron rakes to clean the waste chips. This cleaning method is highly dependent on manual labor and is inefficient. At the same time, the cutting fluid and waste chips are mixed together during the processing of the machine tool, which is difficult to separate. The cleaning process is prone to waste of cutting fluid and environmental pollution.

[0004] In order to solve the above problems, there is an urgent need for a device that can automatically clean up waste chips and keep the processing environment clean, so as to improve gear production efficiency and reduce production costs. Summary of the invention

[0007] By adopting the above technical solution and setting up a waste chip cleaning device, when producing and processing gears, the material blank is fixed on the workbench, and the workbench slides on the first sliding mechanism so that the workpiece approaches the spindle body, and the spindle body clamps the tool and rotates at high speed. At the same time, the spindle body slides on the second sliding mechanism so that the spindle drives the tool to contact the material blank to process the blank raw material. While the tool is in contact with the material blank, the workbench and the spindle body are constantly moving, so that different positions of the material blank are processed to form gear parts. During the processing, the tool rotates to cut the material blank, generating a large amount of waste chips that gather on the workbench. At the same time, during the processing, When cutting gear parts, the oil spray unit will spray cutting fluid on the surface of the tool and the workpiece, thereby cooling the tool and the workpiece to improve the surface quality of the workpiece and extend the service life of the tool. At this time, a mixture of waste chips and cutting fluid gathers on the surface of the worktable; the waste chips and cutting fluid on the surface of the worktable are sprayed by the cleaning mechanism, so that the waste chips and cutting fluid are blown onto the separation mechanism under the worktable, and the separation mechanism filters the cutting fluid and waste chips.

By arranging multiple cutting fluid nozzles on the high-pressure oil pipe, the cutting fluid is sprayed out from the cutting fluid nozzles to form a high-pressure liquid flow, which is sprayed onto the tool and the workpiece respectively to cool the tool and the workpiece. At the same time, after the processing is completed, the workbench is moved and the cutting fluid nozzle sprays cutting fluid onto the workbench, so that the waste chips on the workbench can be blown off to the separation mechanism under the workbench, thereby realizing the cleaning of the waste chips.

[0010] In a specific feasible implementation scheme, the separation mechanism includes a conveyor, which is fixedly arranged above the oil tank body, and the conveyor includes a conveyor bracket, a conveyor roller, a conveyor belt and a drive motor.

[0015] By adopting the above technical solution and setting up a fixed cleaning component, when carrying out gear production and processing, an external high-pressure gas source inputs high-pressure gas into the high-pressure gas pipe, and the high-pressure gas is ejected through a high-pressure nozzle.

[0041] The implementation principle of the waste chip cleaning device of the gear processing machine tool of the first embodiment of the present application is as follows: when producing and processing gears, the material blank is fixedly placed on the workbench 13, and the workbench 13 slides on the first sliding mechanism 121, so that the workpiece approaches the spindle body 142, and the spindle body 142 clamps the tool and rotates at high speed. At the same time, the spindle body 142 slides on the second sliding mechanism 143, so that the spindle body 142 drives the tool to contact with the material blank, and the blank raw material is processed. While the tool is in contact with the material blank, the workbench 13 and the spindle body 142 are constantly moving. Thus, different positions of the material blank are processed to form gear parts. During the processing, the tool rotates to cut the material blank, generating a large amount of waste chips and gathering on the workbench 13. At the same time, during processing, the high-pressure oil pump 161 extracts cutting fluid from the cutting fluid tank 15 and pumps it into the high-pressure oil pipe 162. The cutting fluid is sprayed from the cutting fluid nozzle 163 to form a high-pressure liquid flow. The high-pressure liquid flow is sprayed onto the tool and the workpiece respectively to cool the tool and the workpiece. When the workbench 13 is moved, the high-pressure liquid flow blows the waste chips on the workbench 13 onto the conveyor 31 below. After the processing is completed, the tool is removed, the brush 22 is clamped on the spindle body 142, the spindle body 142 and the workbench 13 are moved, so that the brush 22 contacts the workbench 13. During the movement of the workbench 13 and the spindle body 142, the brush 22 cleans different positions of the workbench 13 and cleans the waste chips that are not blown clean onto the conveyor 31. The waste chips on the conveyor 31 are mixed with the cutting fluid, and the cutting fluid flows down from the filter holes 3131 on the conveyor belt 313 and flows into the cutting fluid tank 15 for circulation. The waste chips gather on the conveyor belt 313, and the drive motor 314 is started, which drives the conveyor roller 312 to rotate. The conveyor belt 313 follows the movement of the conveyor roller 312, and the conveyor belt 313 transports the waste chips to the waste chip briquetting machine 41 outside the machine tool body 1.

[0042] In the initial state, the hydraulic station 415 drives the second hydraulic cylinder 4132 to extend, so that the side plate 4131 blocks the side wall of the mold frame 411. Then, the hydraulic station 415 drives the first hydraulic cylinder 4121 to contract, so that the top plate 4123 is opened, and the waste chips are discharged from the output end of the conveyor belt 313 and fall into the inner cavity of the mold frame 411. When the waste chips fill the inner cavity of the mold frame 411, the first hydraulic cylinder 4121 extends, and one end of the top plate 4123 rotates around the opposite side walls of the mold frame 411, and the other end is located in the mold frame 411, The part is blocked, and then the push hydraulic cylinder 4141 extends, and the push hydraulic cylinder 4141 drives the push plate 4142 to slide along the inner cavity of the mold frame 411 to compress the waste chips. The side plate 4131 and the top plate 4123 limit the waste chips to prevent the waste chips from leaking out of the inner cavity of the mold frame 411. Under the extrusion of the push plate 4142, the waste chips are pressed into dense waste chip blocks, which reduces the gaps between the waste chips and combines the waste chips together, reducing the space occupation, and preventing the waste chips from being scattered everywhere during the transportation and recycling process, thereby improving the cleanliness of the production and processing environment. Finally, the second hydraulic cylinder 4132 contracts, driving the side plate 4131 to rise upward, and the side wall of the mold frame 411 opens. A waste chip collection vehicle can be set on the outside of the side plate 4131 assembly 413, and the push hydraulic cylinder 4141 pushes the waste chip blocks out of the inner cavity of the mold frame 411 and into the waste chip collection vehicle, and the waste chip collection vehicle collects and stores the waste chip blocks.
