Description

Technical Field

[0001] This utility model relates to the field of cutting tool processing technology, specifically a tool cutting edge fixing device. Background Technology

[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. The vast majority of cutting tools are machine-made, but some are hand-made. During the production process of cutting tools, fixing devices are needed to stably clamp and position the tools so that patterns can be engraved on the tools and the cutting edges can be polished to give the tools specific physical properties and thus optimize their performance.

[0003] According to the tool cutting edge fixing device disclosed in announcement number CN221658766U, a machining table is included. A surrounding plate is fixedly installed on the top of the machining table. A drive motor is fixedly installed on the outer side of the surrounding plate. A telescopic column is movably installed on the inner side of the surrounding plate. A connecting plate is fixedly installed at one end of the telescopic column. A connecting column is fixedly installed at one end of the connecting plate. A pressure sensor is fixedly installed at one end of the connecting column. A fixing plate is fixedly installed on one side of the pressure sensor. The beneficial effect of this utility model is that the telescopic column is extended and retracted by the drive motor, thereby fixing the tool in sequence by the connecting plate, the connecting column, the pressure sensor, the fixing plate, and the fixing fixture. When the fixing fixture is tightly attached to the tool, the telescopic column continues to extend and retract. At this time, since the length of the fixing plate and the fixing fixture remains unchanged, the pressure sensor at the connecting column generates pressure, and the pressure of fixing the tool at the fixing fixture can be measured.

[0004] The device calculates the optimal fixing pressure for grinding after multiple measurements, making it easier for workers to grind and fix tools of the same thickness, thus increasing their comfort. According to the instruction manual and attached drawings, the collection groove at the top of the processing table can collect the grinding debris, but it needs to be manually cleaned by the workers, increasing their cleaning time.

[0028] Reference Figures 1 to 5 A baffle 10 is symmetrically fixedly installed at the top of the inside of the processing table 1, and the baffle 10 is located directly above the conveyor belt 8.

[0029] The above solution is adopted: the baffle 10 is made of stainless steel plate and is fixed to the processing table 1 by countersunk bolts to prevent material from overflowing. One end of the baffle 10 is coated with Teflon coating. The Teflon coating has a low coefficient of friction, which can reduce the adsorption of impurities on the surface.

[0030] Reference Figures 1 to 5 Inside the processing table 1 and directly below the conveyor belt 8, a scraper 14 is rotatably connected and positioned above the collection box 11. Rotating shafts 15 are symmetrically fixed at both ends of the scraper 14. A protective shell 16 is fixedly installed at one end of the processing table 1. An adjusting disc 18 for adjusting the cleaning angle of the scraper 14 is rotatably connected to one end of the protective shell 16. The rotating shaft 15 passes through the protective shell 16 and is fixedly installed with the adjusting disc 18. A limiting gear 17 is rotatably connected inside the protective shell 16 and is fixedly installed with the rotating shaft 15.

[0031] The above scheme is adopted: the scraper 14 is made of polyurethane, the rotating shafts 15 at both ends are made of steel and form a clearance fit with the bearing seats (6203ZZ bearings) on both sides of the processing table 1, the adjusting plate 18 is made of gray cast iron, the limiting gear 17 is keyed to the rotating shaft 15, the limiting block 20 is made of steel and forms a clearance fit with the empty groove 19, the return spring 22 is made of steel and provides locking force, pulling the connecting rod 21 can make the limiting block 20 disengage from the tooth groove of the limiting gear 17, and after rotating the adjusting plate 18 to the target angle, it is released, and the limiting block 20 is relocked under the action of the return spring 22.

[0032] The working principle of this utility model is as follows: When the cutting edge of the tool is processing on the fixture assembly 2, the generated waste chips fall into the collection groove 4 below. The rotating motor 9 is started, and its output shaft drives the active roller shaft 7 to rotate. The active roller shaft 7 drives the driven roller shaft 6 to rotate synchronously via the transmission belt 8. The transmission belt 8 is located directly below the collection groove 4, and the waste chips fall directly onto it. During operation, the transmission belt 8 transports the waste chips to the collection box 11. The collection box 11 is slidably engaged with the processing table 1 via the bottom locking slide rod 13, facilitating installation and disassembly. The operator only needs to pull the handle 12 to remove the collection box 11 to clean the waste chips, greatly reducing the time and workload of manual waste chip collection. When adjusting the angle of the scraper 14, the connecting rod 21 is pulled, and the connecting rod 21 drives the limit block 20 to... The return spring 22 slides and compresses within the slot 19, causing the limit block 20 to disengage from the tooth groove of the limit gear 17, thus releasing the lock on the scraper 14. At this time, the adjustment disc 18 is rotated, and the adjustment disc 18 drives the scraper 14 to rotate via the rotating shaft 15. The tilt angle of the scraper 14 is adjusted according to the adhesion of impurities on the surface of the conveyor belt 8. After adjustment, the connecting rod 21 is released, and under the elastic force of the return spring 22, the limit block 20 is re-engaged into the tooth groove of the limit gear 17, fixing the angle of the scraper 14. The baffle 10 at the top of the inside of the processing table 1 prevents waste chips from splashing to the outside of the conveyor belt 8. The scraper 14 with the adjusted angle can fit more closely to the surface of the conveyor belt 8, effectively scraping away the adhering impurities when the conveyor belt 8 is running, ensuring the cleanliness of the conveyor belt 8 and maintaining the smooth transmission of waste chips.
