Description

Technical Field

[0001] This utility model relates to the field of collet processing technology, specifically a collet inner hole processing device. Background Technology

[0002] The opening of the inner hole of the collet usually requires multiple processing steps. Among them, deburring the edge of the inner hole of the collet, especially the end face of the clamping hole and the edge of the slot, is a key process to ensure clamping accuracy, prevent scratching the workpiece, and avoid stress concentration that leads to cracking.

[0003] To avoid altering the inner hole or slot size during deburring, magnetic polishing machines are currently used to deburr the inner hole edges and slotted edges of collets. This is done by pouring the collet into a container filled with magnetic steel needles, adding water, and then driving the magnetic steel needles to rotate at high speed. The magnetic steel needles come into contact with the collet during rotation, thus polishing the edges of small holes. However, the magnetic polishing machines currently in use require manual separation of the collet and magnetic steel needles after polishing, which is quite time-consuming.

[0004] A search revealed a magnetic grinding device disclosed in patent application publication number CN106737116B, which includes a grinding barrel and a filter screen installed inside the grinding barrel. The filter screen separates the workpiece from the magnetic steel needle and automatically pours out the workpiece.

[0005] However, due to the high-speed rotation of the magnetic steel needles, the surface will be slightly magnetized and water will adhere to it, causing some magnetic steel needles to stick to the outside of the collet or the filter screen, increasing the workload of steel needle sieving during subsequent cleaning; and after the steel needles are carried away, the number of magnetic steel needles in the magnetic grinder will decrease, which may affect the next batch of collet burr grinding. Utility Model Content

[0006] The purpose of this utility model is to provide a collet inner hole processing device. By setting a canopy on the top of the magnetic grinder to install a filter screen lifting structure and a magnetic attraction structure, after the collet is retrieved, the magnetic attraction structure sweeps above the filter screen and the collet, attracting the magnetic steel needles adhering to the collet and the filter screen, reducing the amount of steel needles carried away from the grinding equipment. After the collet is manually unloaded, the magnetic steel needles on the surface of the magnetic rod are removed and returned to the grinding pool of the magnetic grinder.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a collet inner hole processing device, comprising a magnetic grinding machine for grinding burrs on the edge of the collet inner hole, wherein the magnetic grinding machine is provided with a filter screen capable of retrieving the ground collet and a connecting structure for longitudinally sliding the filter screen within the grinding pool of the magnetic grinding machine, the top of the magnetic grinding machine is fixed with a canopy by a support rod, a lifting structure for driving the filter screen to rise and fall is installed above the canopy, and a magnetic suction structure capable of removing magnetic steel needles from the surface of the filter screen and the collet is installed below the canopy.

A guide ring that can reduce the friction between the cable and the canopy is fixed in the through hole. The two ends of the cable pass through the two sets of through holes respectively and are bolted to the horizontal rods of the two connecting rods respectively.

[0010] Preferably, the lifting structure further includes a rotating motor, which is mounted on the lower surface of the ceiling by screws. A winding plate is fixed to the output end of the rotating motor, and the cable is wound around the outer wall of the winding plate.

[0011] Preferably, the winding plate is arranged in an I-shape, and the cable is wound around the outer wall of the winding plate at least once.

[0012] Preferably, the magnetic attraction structure includes a magnetic rod and a swinging structure capable of driving the magnetic rod to swing.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a collet inner hole processing device, including a magnetic grinding machine 1 for grinding burrs on the edge of the collet inner hole, the magnetic grinding machine 1 is provided with a filter screen 2 for retrieving the ground collet, and a connecting structure 3 for longitudinally sliding the filter screen 2 in the grinding pool of the magnetic grinding machine 1, the top of the magnetic grinding machine 1 is fixed with a canopy 4 by a support rod, a lifting structure 5 for driving the filter screen 2 to rise and fall is installed above the canopy 4, and a magnetic suction structure 6 for removing magnetic steel needles from the surface of the filter screen 2 and the collet surface is installed below the canopy 4.

[0020] After the magnetic grinding machine 1 finishes grinding the burrs inside the collet, the built-in filter screen 2 uses the lifting structure 5 to retrieve the collet from the grinding pool. The magnetic attraction structure 6 sweeps across the surface of the retrieved collet to attract the magnetic steel needle.

[0021] The connecting structure 3 includes a frame 301 fixed to the edge of the filter screen 2. Connecting rods 302 are fixed to the upper surfaces of both ends of the frame 301. The connecting rods 302 are arranged in an inverted L shape. A guide rod 303 is fixed to one end of the horizontal rod of the connecting rod 302. Guide blocks 304 are fixed to both sides of the outer wall of the magnetic grinding machine 1. The guide rod 303 is slidably connected in the guide block 304.

[0022] The frame 301 at the edge of the filter screen 2 provides rigid support, and the guide rod 303 at the end of the connecting rod 302 is embedded in the guide block 304 fixed to the side wall of the grinder to form a vertical slide rail. This ensures that the filter screen 2 remains stable during lifting and lowering, moves vertically along a predetermined path, and avoids shaking or tilting.

[0023] The lifting structure 5 includes a cable 501. The upper surface of the canopy 4 has two sets of through holes 502 for the cable 501 to pass through. A guide ring 503 is fixed in the through hole 502 to reduce the friction between the cable 501 and the canopy 4. The two ends of the cable 501 pass through the two sets of through holes 502 respectively and are bolted to the horizontal rods of the two connecting rods 302 respectively.

[0024] The cable 501 passes through the guide ring 503 inside the through hole 502 of the ceiling 4, and its two ends are respectively attached to the horizontal bars of the connecting rods 302 on both sides. The guide ring 503 is arranged in a ring and has a circular longitudinal section. During lifting and lowering, the cable 501 transmits tension or lowers the filter screen 2 through the guide ring 503.

[0025] The lifting structure 5 also includes a rotating motor 504, which is installed on the lower surface of the ceiling 4 by screws. The output end of the rotating motor 504 is fixed with a winding plate 505, and the cable 501 is wound around the outer wall of the winding plate 505.

[0026] The winding plate 505 is arranged in an I-shape, and the cable 501 is wound around the outer wall of the winding plate 505 at least once.

[0027] A rotating motor 504 drives an I-shaped winding plate 505 to rotate. A cable 501 is wound in the groove of the winding plate 505, with at least one turn providing sufficient friction. Rotating the motor 504 forward winds up the cable 501, lifting the filter screen 2; rotating the motor 504 in reverse releases the cable 501, causing the filter screen 2 to descend due to gravity. The I-shaped design prevents the cable 501 from slipping out of the groove, ensuring reliable lifting.

[0028] The magnetic attraction structure 6 includes a magnetic rod 601 and a swinging structure capable of driving the magnetic rod 601 to swing. The swing structure includes a rotating motor 602 and a mounting plate 603 that provides a mounting position for the rotating motor 602. One end of the magnetic rod 601 is rotatably connected to the bottom of the mounting plate 603 via a rotating shaft. The rotating motor 602 is mounted on the top of the mounting plate 603 by screws. The output end of the rotating motor 602 is fixedly connected to the rotating shaft of the magnetic rod 601.

[0029] The magnetic rod 601 generates a strong magnetic field, and the rotating motor 602 of the oscillating structure drives the magnetic rod 601 to oscillate horizontally around its axis. When the filter screen 2, carrying the collet, rises above the water surface, the oscillating magnetic rod 601 sweeps across the surface of the filter screen 2 and the collet, using magnetic force to attract and remove any magnetic steel needles that are weakly magnetized or adhered to by water, thus reducing the number of magnetic steel needles flowing into the next process.

[0030] The magnetic attraction structure 6 also includes a lifting mechanism 7 that provides lifting power to the magnetic rod 601 so that the collet can unload material from the filter screen 2; The lifting mechanism 7 includes an electric push rod 701 installed on the top of the ceiling 4. A connecting plate 702 is fixed to the telescopic end of the electric push rod 701. Straight rods 703 are fixed to both ends of the connecting plate 702. The straight rods 703 penetrate the ceiling 4 and are slidably connected to the ceiling 4. The bottom ends of the two sets of straight rods 703 are respectively fixedly connected to both ends of the mounting plate 603.

[0031] The electric push rod 701 extends and retracts, causing the connecting plate 702 and the straight rod 703 fixed thereto to move up and down. The straight rod 703 slides through the ceiling 4. Specifically, when the electric push rod 701 retracts, the straight rod 703 and the connecting plate 702 move downwards, the mounting plate 603 moves downwards, and the magnetic rod 601 approaches the filter screen 2 or the collet to sweep and adsorb.

[0032] The electric push rod 701 extends, the straight rod 703 and the connecting plate 702 move upward, the mounting plate 603 moves upward, and the magnetic rod 601 is lifted, providing operating space for manual removal of the collet and avoiding interference.

[0033] In use, the collet is inserted into the grinding tank of the magnetic grinder 1 for deburring of the inner hole. The grinding structure of the magnetic grinder 1 is the same as that of the prior art and will not be described in detail. After grinding, the motor 504 is rotated to wind up the cable 501, and the filter screen 2 carrying the collet is vertically lifted out of the grinding tank through the connecting rod 302. When the electric push rod 701 retracts, the straight rod 703 and the connecting plate 702 move downwards, the mounting plate 603 moves downwards, the magnetic rod 601 comes into contact with the filter screen 2 or the collet, the rotating motor 602 starts, causing the magnetic rod 601 to rotate, and the magnetic rod 601 sweeps and adsorbs the filter screen 2 and the collet above. After adsorption is completed, the electric push rod 701 extends, the straight rod 703 and the connecting plate 702 move upward, the mounting plate 603 moves upward, and the magnetic rod 601 is lifted, providing operating space for manual removal of the collet and avoiding interference; The steel needles adsorbed on the surface of magnetic rod 601 are manually peeled off and recycled into the grinding tank to maintain the concentration of steel needles. Rotating motor 504 releases cable 501, causing filter screen 2 to descend and return to its original position, ready for the next batch of processing.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
