Description

Technical Field

[0001] The invention belongs to the field of machining tool setting equipment, and in particular relates to an automatic screening system for the use status of a transfer tool. Background Art

[0002] In the process of machining production, when some smaller factories with fewer equipment need to process multiple products, they often need to frequently replace tools to process different products due to limited tool magazines and the limited number of machine tools. When replacing products, the tools of old products on the machine tools need to be removed for temporary storage. When they need to be used again, they need to be manually proofread and then replace the tools in use on the machine tools. For some factories with a high frequency of product replacement, workers need to send the removed tools to the tool magazine, and tool maintenance personnel manually proofread the wear of tools for different products. They also need to manually clean the iron filings on the tools and move them one by one to the tool setting instrument for tool setting screening and debugging, which is a huge workload.

[0003] The existing tool setting instrument only has the function of tool setting, and cannot complete automatic loading, automatic calibration and screening. When there are too many types of tools and the replacement frequency is too high, a lot of manual work is required, the production rhythm will be reduced, and the error rate will increase.

[0004] The patent document with application number "CN201621477622.4" discloses a high-sensitivity tool setting instrument, including a column, a base, a standard seat located on the base, a glass scale grating, a grating reading head, a Z-axis moving block and a bracket connected to the Z-axis moving block; the grating reading head further includes a left side plate, a right side plate, a base plate, an aperture plate, a left convex lens, a right convex lens and an indicator grating located directly below the aperture plate, the two ends of the base plate are respectively fixed to the upper ends of the left side plate and the right side plate, the indicator grating is connected to the lower ends of the left side plate and the right side plate, the aperture plate is located between the base plate and the indicator grating, and the indicator grating has a first line strip area and a second line strip area arranged in parallel; a left infrared light emitter and a right infrared light emitter are installed on the lower surface of the base plate, a left through hole and a right through hole are opened on the aperture plate, and the left convex lens is located between the left infrared light emitter and the left through hole. The tool setter in the comparative document still has a traditional vertical tool setter structure, which still requires manual operation when loading and unloading materials, and does not have an automatic sorting function, and cannot shorten the production cycle.

[0049] Next, the working principle of an automatic nuclear screening system for the use status of a transfer tool in this embodiment is described in detail so that those skilled in the art can better understand the present invention:

[0050] During use, the machine tool operator first places the replaced tools on the tool cart 100. When placing them, each row needs to be filled with tool holders 110 and the direction of the clearance grooves 111 is consistent with the width direction of the tool cart 100. If there are not enough tools, empty tool holders 110 are placed to fill the vacancies in each row. Then the tool cart 100 is pushed to the loading port 220, so that the docking port 131 is docked with the loading port 220. Then the pushing assembly 300 can push the tool holders 110 into the circulation channel 210 in the form of a whole row, and the pull rod 211 drives the rotating head 212 to extend into the clearance groove 111. At this time, the direction of the block 213 is consistent with the pull rod 211. The block 213 can extend from the side of the connector 123 into the slot 121. When the elastic block 214 on the block 213 is inserted into the positioning slot 124, the pull rod 211 stops moving. At this time, the block 213 rotates 90 degrees to a state perpendicular to the pull rod 211. Then the pull rod 211 moves forward to pull the tool holder 110 into the working area of ​​the air blowing device 700. The block 213 drives the tool sleeve 120 to rotate 180 degrees, so that the air blowing device 700 blows off the iron filings on the tool. Then the pull rod 211 continues to move forward to the working area of ​​the tool setting instrument 800. The block 213 drives the tool sleeve 120 to rotate 180 degrees, so that the tool setting instrument 800 is used to calibrate it. If the degree of wear of the tool is within a predetermined range, it is considered qualified. The pull rod 211 drives the tool holder 110 where the tool is located to move to the discharge port 240 and is blocked by the second blocking portion 620 or the previous tool holder 110 located at the rejection port 230. Then the clamping block 213 rotates to a state parallel to the pull rod 211 and withdraws from the clamping slot 121 to continue pulling the next tool holder 110. When the tool holders 110 on the second conveyor belt 600 accumulate to a total width that is consistent with the width of the discharge port 240, the pull rod 211 drives the rotating head 212 to move to the waiting area 630, and the second conveyor belt 600 starts to transport the entire row of tool holders 110 to the storage area 630. The tool holder 110 is transferred to the end of the second fence 610 for storage; if the degree of wear of the tool is outside the predetermined range, it is considered unqualified and needs to be replaced or adjusted, then the pull rod 211 drives the tool holder 110 where the tool is located to move to the anti-slip plate 530 at the rejection port 230, and then the rejection plate 400 pushes the tool holder 110 into the first fence 510 and is blocked by the first blocking part 520. When the width of the tool holder 110 where the unqualified tool is located accumulates to a full row, the first conveyor belt 500 starts to transfer the rows of tool holders 110 to the end of the first blocking part 520 for storage, waiting for the tool administrator to take them to replace or adjust the tool.

[0051] To sum up, the tool cart 100 in this embodiment can be docked with the circulation channel 210 and the tool holder 110 can be automatically pushed into the circulation channel 210 by the pushing assembly 300. A blowing device 700 and a tool setting instrument 800 are provided along the circulation channel 210. Through the pull rod 211 and the rotating head 212, the tool holder 110 can carry the tool through the blowing device 700 and the tool setting instrument 800 in turn and clean and calibrate the tool. Finally, the tool holder 110 is rejected and screened by the rejection plate 400, the first conveyor belt 500 and the second conveyor belt 600, so that over-worn tools and qualified tools are diverted, replacing manual cleaning, calibration and screening of tools, saving time and labor costs.
