[0002] During the production and processing of bevel gears, it is necessary to fix the tooth blank of the bevel gear and process the tooth grooves on the outer edge of the bevel gear through a gear shaping machine or a slotting machine. The existing positioning mechanism for bevel gear processing has a cumbersome installation structure when in use, requires multi-step positioning, increases installation errors, and is difficult to achieve one-click clamping, which is not conducive to automated production. In addition, when processing the tooth grooves of the bevel gear blank, a large amount of iron chips are generated, which are difficult to collect. At the same time, the iron chips are more likely to fall into the positioning structure, causing the positioning structure to get stuck, and in severe cases, it is easy to cause indentations on the surface of the bevel gear.

By utilizing the lever principle and combining the conical structure of the cone block, the pressure plate presses the tooth blank while the expansion block squeezes and positions the inner ring of the tooth blank through pressure extrusion, thereby achieving the technical effect of one-click clamping, which is beneficial to the automatic processing of the bevel gear tooth groove; in addition, the pre-action principle is adopted to clean the debris after the bevel gear is processed through a magnetically controlled chip collection mechanism.

At this time, the end of the first rocker close to the positioning groove is tilted upward, and this end rotates out of the coverage range of the positioning groove without affecting the movement of the push rod; When in use, the pressure plate is pressed to the upper surface of the gear blank. During this process, the upper surface of the gear blank squeezes the lower end of the pressing block, and the pressing block is pressed upward, so that the end of the third rocker plate overcomes the return spring and moves up. According to the lever principle, when the pressure plate is fully pressed onto the upper surface of the gear blank, the third rocker plate drives the second rocker plate, and the second rocker plate drives the first rocker plate. During this process, the two ends of the second rocker plate adaptively extend and retract, so that the first rocker plate moves down close to one end of the push rod, and one end of the first rocker plate rotates and presses down into the positioning groove, and presses the push rod downward again a short distance, thereby moving the cone block down to tighten the sliding plate, so that the expansion block squeezes and positions the inner ring of the gear blank, and the expansion block expands and squeezes the inner ring of the positioning gear blank, determines the radial reference of the gear blank, and the pressure plate presses the upper surface of the gear blank, fixes the gear blank on the rotating disk, determines the axial reference of the gear blank, and realizes the technical effect of one-button clamping.

During the tooth groove processing of the tooth blank, the inclined blowing plate blows air toward the tooth groove processing to remove iron chips. The rotating motor is started, and the rotating magnetic disk continuously absorbs the blown-off iron chips and transfers the iron chips to the chip collection groove. The part of the magnetic disk that is transferred out of the chip collection groove is scraped off the iron chips on its surface by the scraper plate. The scraped iron chips fall into the chip collection groove and are uniformly processed after processing, thereby achieving the technical effect of timely cleaning of iron chips.

A push rod 25 is provided on the inner side of the pressing plate 23 for coaxial sliding. A limiting plate 29 is provided on the upper part of the push rod 25.

The outer wall of the push rod 25 is evenly distributed with positioning grooves 30. The circumferentially distributed positioning grooves 30 are arranged in a linear array along the axial direction of the push rod 25. The lower wall of the pressure plate 23 is evenly distributed with movable grooves 31. The movable grooves 31 pass through the inner side of the pressure plate 23.

The first rocker plate 34, the second rocker plate 35, and the third rocker plate 36 are respectively rotatably arranged in the movable groove 31. The rotation axes of the first rocker plate 34, the second rocker plate 35, and the third rocker plate 36 are on the same horizontal plane. The first rocker plate 34 is arranged on a side of the movable groove 31 close to the positioning groove 30.

The second rocker plate 35 is rotatably connected to the first rocker plate 34 is away from one end of the push rod 25, the third rocker 36 is rotatably connected to the end of the second rocker 35 away from the first rocker 34, the two ends of the second rocker 35 are telescopic structures, and a pressing block 37 is provided at the lower part of the end of the third rocker 36 away from the second rocker 35, and the lower part of the pressing block 37 is arc-shaped; the upper wall of the movable groove 31 is connected to the reset spring 32, and the lower end of the reset spring 32 is connected to the reset plate 33, and the reset plate 33 is movably provided above the end of the third rocker 36 away from the second rocker 35.

[0022] Working principle and workflow: In the initial state, the hydraulic telescopic column 7 is in a fully retracted state. Under the elastic action of the pressure spring 27, the limiting plate 29 contacts the upper part of the pressure plate 23, and the push rod 25 moves away from the pressure plate 23; under the elastic action of the return spring 32, the return plate 33 pushes one end of the third rocker 36, so that the rotation connection end of the third rocker 36 and the second rocker 35 is tilted upward, and then the rotation connection end of the second rocker 35 and the first rocker 34 is at the bottom. At this time, the end of the first rocker 34 close to the positioning groove 30 is tilted upward, and the end is rotated out of the coverage range of the positioning groove 30 without affecting the movement of the push rod 25; the magnetic sheet 22 and the magnetic ring 43 are attracted to each other, the cone block 15 is at the upper end of the center tube 12, and the extrusion slider 21 is at the lower end of the extrusion slide 20, so that the sliding plate 16 slides into the center tube 12, and the circumferential diameter formed by the outer edge of the expansion block 17 is the minimum value.

[0023] When in use, the device is used in conjunction with a manipulator to put the gear blank 10 onto the extrusion type inner shaft positioning assembly 3, and then the hydraulic telescopic column 7 is started, and the hydraulic telescopic column 7 pushes the extrusion mechanism 9 to move downward, and the electromagnetic plate 26 gradually extends into the inner ring of the gear blank 10 and the center tube 12. At this time, the electromagnetic plate 26 is energized to generate magnetism, and the electromagnetic plate 26 absorbs the magnetic sheet 22, so that the electromagnetic plate 26 and the cone block 15 form a whole. Under the elastic action of the pressure spring 27, the push rod 25 pushes the cone block 15 to move downward, and the cone block 15 moves downward to squeeze the sliding plate. 16, the extrusion slider 21 moves upward relatively in the extrusion chute 20, so that the sliding plate 16 uniformly distributed on the circumference slides toward the outside of the center tube 12 under the restriction of the limit groove 14, and the tightening block 17 is squeezed outward, and the copper foil 18 is squeezed and fitted with the inner ring of the gear blank 10 until the pressure plate 23 is pressed to the upper surface of the gear blank 10. In this process, the upper surface of the gear blank 10 squeezes the lower end of the pressing block 37, and the pressing block 37 is pressed upward to make the end of the third rocker 36 overcome the reset spring 32 and move upward. According to the principle of lever, when the pressing block 17 is pressed, the lower end of the pressing block 37 is pressed upward. When the plate 23 is completely pressed onto the upper surface of the gear blank 10, the third rocker 36 drives the second rocker 35, and the second rocker 35 drives the first rocker 34. During this process, the two ends of the second rocker 35 adaptively extend and retract, causing the first rocker 34 to move downward close to the end of the push rod 25. One end of the first rocker 34 rotates and presses down into the positioning groove 30, and the push rod 25 is pressed down again for a short distance, thereby causing the cone block 15 to move downward to press the sliding plate 16, so that the expansion block 17 squeezes the inner ring of the positioning gear blank 10, and the copper foil 18 is compressed. It is in close contact with the gear blank 10, avoiding the pressure of the expansion block 17 directly acting on the inner side of the gear blank 10, reducing indentations or scratches, and at the same time increasing the friction between the gear blank 10 and the copper foil 18, improving the anti-loosening ability of the expansion block 17 and enhancing the positioning reliability; the expansion block 17 expands and squeezes the inner ring of the positioning gear blank 10, determining the radial reference of the gear blank 10, and the pressure plate 23 presses the upper surface of the gear blank 10, so that the gear blank 10 is fixed on the rotating disk 11, determining the axial reference of the gear blank 10, and achieving the technical effect of one-button clamping.

[0024] Then, a slotting machine is used to process the tooth grooves of the gear blank 10. During this process, the main power motor can be used to rotate the extrusion type inner shaft positioning assembly 3 to adapt to the slotting position, and the follower type pressing assembly 4 that presses the gear blank 10 follows the rotation on the connecting frame 2. At the same time, the air pump 42 is started, and air is blown toward the tooth groove processing position through the inclined blowing plate 8 to remove iron chips. The rotating motor 40 is started, and the rotating magnetic disk 41 continuously absorbs the blown-off iron chips and carries them to the chip collecting groove 38. The part of the magnetic disk 41 that rotates out of the chip collecting groove 38 is scraped off the iron chips on its surface by the scraping plate 39. The scraped iron chips fall into the chip collecting groove 38 and are uniformly processed after processing, thereby achieving the technical effect of timely cleaning the iron chips. At the same time, the setting of the pressing plate 23 covers the upper opening of the gear blank 10, so that the iron chips cannot fall into the interior of the extrusion type inner shaft positioning assembly 3, thereby ensuring its positioning effect. After the processing of a single gear is completed, the hydraulic telescopic column 7 contracts and moves upward, the pressure plate 23 moves upward, and under the elastic action of the return spring 32, one end of the third rocker 36 moves downward, thereby driving the first rocker 34 to reset through the second rocker 35. The end of the first rocker 34 close to the push rod 25 no longer presses the positioning groove 30. When the pressure plate 23 drives the push rod 25 to move upward, the electromagnetic plate 26 attracts the magnetic sheet 22, driving the cone block 15 to move upward synchronously, thereby causing the extrusion slide 21 to slide relatively in the extrusion chute 20, thereby pulling the circular The expansion blocks 17 evenly distributed around the circumference are retracted toward the center tube 12 and no longer squeeze the inner ring of the positioning gear blank 10 until the electromagnetic plate 26 drives the cone block 15 to move up to the upper end of the center tube 12. The electromagnetic plate 26 is powered off and demagnetized. At this time, the magnetic sheet 22 and the magnetic ring 43 are attracted to each other again, so that the cone block 15 is at the upper end of the center tube 12, and the extrusion type inner shaft positioning assembly 3 and the follower type clamping assembly 4 are reset synchronously; then the processed gear is removed by the robot, and the next gear blank 10 is put onto the extrusion type inner shaft positioning assembly 3.

[0025] The above is the overall workflow of the present invention. Just repeat this step next time you use it.
