Description

Technical Field

[0001] The invention relates to the technical field of gear processing, and in particular to a high-precision gear punching device. Background Art

[0002] During the gear production process, it is often necessary to drill holes on the gears to meet requirements such as installing pins, reducing weight, and achieving specific functions.

[0003] There are some problems with existing gear punching equipment. For example, it is difficult to ensure the punching accuracy. During the punching process, due to factors such as gear vibration and inaccurate positioning, the position deviation of the punched holes is large, which affects the subsequent assembly and performance of the gear.

[0004] Therefore, it is necessary to use pin blocks or the like to fit into the tooth grooves of the gears to clamp and fix the gears. However, since the pin blocks are usually arranged around the gears to be clamped and are limited by the structure, the circumferential positions of the pin blocks are usually fixed. However, since the number of teeth on the gears is not fixed, it is impossible to ensure that each pin block fits exactly into the tooth groove, which affects the fixing effect of the gears.

[0005] In addition, a lot of debris is usually generated during the process of drilling holes in gears. If it is not cleaned in time, the accuracy of drilling will be affected. Since different gears have different requirements for materials, sizes, and apertures, it is necessary to flexibly adjust the drill pipe speed. Due to the influence of the speed, the distribution range of the debris generated is different. Therefore, the conventional vacuum adsorption method cannot achieve a good cleaning effect.

After the pressure applied by the drill rod fixes the gear, the rotation of the drill rod is controlled to drill holes in the gear.

[0018] 3. By setting up a drilling dust removal structure, the fixed ring drives the first swing arm and the second swing arm to rotate in a circle. In the process of the first swing arm and the second swing arm driving the magnetic component to rotate in a circle, an annular magnetic range can be formed to attract and clean the metal debris scattered from the drilling hole.

DETAILED DESCRIPTION

[0020] like Figure 1-9 As shown, a high-precision gear punching equipment comprises a base 1, the upper end of which is provided with a pressure fixing structure, the pressure fixing structure comprises a plurality of first L-shaped blocks 7 which are symmetrically arranged and can slide the same distance after being pressed, the first L-shaped block 7 is provided with an adapting structure, the adapting structure comprises a first tooth block 15 and a second tooth block 16, the first tooth block 15 and the second tooth block 16 can be combined and enter into the tooth groove of the gear 6 to stabilize the gear 6, and can also be stabilized by inserting the protruding serrations of the gear 6 by deflecting towards each other, the upper end of the base 1 is provided with a supporting slide plate 3 which can slide up and down with a limit position, the supporting slide plate 3 is provided with a punching and dust removal structure, the punching and dust removal structure comprises a rotatable drill rod 37, the two ends of the drill rod 37 are respectively provided with a first swing rod 25 and a second swing rod 29 with adjustable deflection angles, and the ends of the first swing rod 25 and the second swing rod 29 are provided with magnetic components which can attract debris generated by drilling. When the present invention is in use, the gear 6 is placed above the first L-shaped block 7, and the support slide plate 3 is controlled to move downward. The support slide plate 3 drives the drill rod 37 to move downward, and the drill rod 37 presses against the gear 6, thereby triggering the pressure fixing structure to work. The first L-shaped block 7 simultaneously and synchronously moves toward the center of the gear 6, and the adaptation structure works. When the first tooth block 15 and the second tooth block 16 are directly opposite to the tooth groove of the gear 6, they are directly inserted into the tooth groove. When the first tooth block 15 and the second gear 18 at the other position are opposite to the protruding sawtooth of the gear 6, the first tooth block 15 and the second gear block 16 are synchronously swung to both sides and inserted into the adjacent tooth grooves on both sides of the sawtooth to fix the gear 6. Therefore, by arranging the first tooth block 15 and the second tooth block 16 that can be opened and closed, gears with different numbers of teeth can be fixed. 6 can achieve a better fixing effect. The gear 6 has different requirements on the rotation speed of the drill rod 37 due to the material, size, aperture, etc. The drilling and dust removal structure can be controlled to work according to the rotation speed of the drill rod 37. By adjusting the deflection angle of the first swing rod 25 and the second swing rod 29, the distance between the magnetic component and the drill rod 37 is changed to ensure that the magnetic component has a better attraction and cleaning effect on the generated debris. At the same time, the drill rod 37 is against the center position of the gear 6. After the pressure applied by the drill rod 37 fixes the gear 6, the rotation of the drill rod 37 is controlled to drill the gear 6. Since the first L-shaped block 7 moves toward the center of the gear 6 at the same time and synchronously, the center positioning effect of the gear 6 is good, which can effectively avoid the drill rod 37 from causing deviation in the drilling position of the central output shaft of the gear 6.

[0021] The pressure fixing structure also includes a sliding bracket 11 arranged at the upper end of the base 1, and the lower end of the sliding bracket 11 is fixedly connected to a sleeve rod 14, and the upper end of the base 1 is provided with a sleeve 13 slidably connected to the sleeve rod 14, and a first spring 10 sleeved and connected to the sleeve 13 is provided between the sliding bracket 11 and the base 1, and a second L-shaped block 8 fixedly connected to the first L-shaped block 7 is slidably arranged on the sliding bracket 11, and the lower end of the second L-shaped block 8 is rotatably connected to a support rod 9, and one end of the support rod 9 is rotatably arranged on the base 1.

[0022] like Figure 2 and 3 As shown, when the gear 6 above the first L-shaped block 7 is compressed, the sleeve rod 14 at the lower end of the sliding bracket 11 slides downward along the inner wall of the sleeve 13, and the first spring 10 is compressed and retracted. At the same time, since the pivot point of one end of the support rod 9 is fixed, the support rod 9 at the upper end of the base 1 deflects inward toward each other. When the support rod 9 deflects downward synchronously, since the length of the support rod 9 is fixed, it can drive the first L-shaped block 7 and the second L-shaped block 8 to move along the inner wall of the sliding bracket 11, so as to center the gear 6 above the first L-shaped block 7.

[0023] The second L-shaped blocks 8 are symmetrically and equidistantly arranged on the sliding bracket 11 , and a sliding pin 12 slidably connected to the inner wall of the sliding bracket 11 is arranged at the lower end of the second L-shaped block 8 .

[0024] like Figure 2 and 3 As shown, when the second L-shaped block 8 moves along the inner wall of the sliding bracket 11 at the same time and distance, the sliding pin 12 plays a role in limiting the sliding of the second L-shaped block 8 .

[0025] The adapting structure also includes a first rotating rod 24 and a second rotating rod 23 rotatably connected to the inner wall of the first L-shaped block 7, the first tooth block 15 and the second tooth block 16 are fixedly arranged on the first rotating rod 24 and the second rotating rod 23 respectively, the upper ends of the first tooth block 15 and the second tooth block 16 are coaxially fixedly provided with a first gear 19 and a second gear 18 respectively, and the first gear 19 and the second gear 18 are meshed with each other, the inner wall of the first L-shaped block 7 is slidably connected with a spur rack 17 meshing with the first gear 19, one end of the spur rack 17 is fixedly connected with a sliding column 21, a sliding shaft block 20 slidably connected to the sliding column 21 is fixedly arranged on the first L-shaped block 7, and a second spring 22 sleeved and connected to the sliding column 21 is arranged between the sliding shaft block 20 and the spur rack 17.

[0026] like Figure 5 and 6 As shown, when the first tooth block 15 and the second tooth block 16 are directly opposite to the tooth groove of the gear 6, the two are fitted and directly placed in the tooth groove. When the first tooth block 15 and the second gear 18 at the other position are directly opposite to the protruding sawtooth of the gear 6, the first tooth block 15 and the second tooth block 16 are synchronously swung to both sides and placed in the adjacent tooth grooves on both sides of the sawtooth to fix the gear 6. When the first tooth block 15 and the second tooth block 16 are synchronously swung to both sides, they respectively drive the first rotating rod 24 and the second rotating rod 23 to rotate. The first rotating rod 24 and the second rotating rod 23 respectively drive the first gear 19 and the second gear 18 to rotate. When the first gear 19 rotates, it can drive the spur rack 17 to slide. The spur rack 17 drives the sliding column 21 to slide along the inner wall of the sliding shaft block 20. The second spring 22 is compressed. By setting the second spring 22, the first tooth block 15 and the second tooth block 16 can be reset to ensure that the two remain in a fitted state when they are not affected by external force.

[0027] The drilling and dust removal structure also includes a motor 4 arranged on a supporting slide plate 3, and the output shaft of the motor 4 is respectively fixed with a fixing ring 32 and a mounting column 33, the first swing arm 25 and the second swing arm 29 are both rotatably set on the fixing ring 32, and the drill rod 37 is set on the mounting column 33.

[0028] like Figure 1As shown, the motor 4 is working, the output shaft of the motor 4 drives the fixed collar 32 and the mounting column 33 to rotate, the mounting column 33 drives the drill rod 37 to rotate to drill the gear 6, and the fixed collar 32 drives the first swing rod 25 and the second swing rod 29 to rotate in a circle.

[0029] One end of the mounting column 33 is fixedly connected to a mounting plate 31, and an electric telescopic rod 30 is arranged on the mounting plate 31. The output end of the electric telescopic rod 30 is fixedly connected to a fixing rod 27, and both ends of the fixing rod 27 are respectively provided with latches 28. The inner walls of the first swing rod 25 and the second swing rod 29 are both provided with sliding grooves 34, and the latches 28 at both ends of the fixing rod 27 are respectively arranged in the sliding grooves 34 of the first swing rod 25 and the second swing rod 29.

[0030] like Figure 8 As shown, the mounting plate 31 supports and fixes the electric telescopic rod 30. When the angle between the first swing rod 25 and the second swing rod 29 needs to be adjusted, the electric telescopic rod 30 can be controlled to work, and the electric telescopic rod 30 drives the fixing rod 27 to move toward each other, and the fixing rod 27 drives the latches 28 at both ends to move downward respectively. When the latches 28 slide in the slide grooves 34 along the first swing rod 25 and the second swing rod 29, since one end of the first swing rod 25 and the second swing rod 29 is rotatably set on the fixing collar 32, when the latches 28 slide in the slide grooves 34 along the first swing rod 25 and the second swing rod 29, the angle between the first swing rod 25 and the second swing rod 29 can be changed, thereby changing the distance between the magnetic component and the drill rod 37, ensuring that the magnetic component has a better effect of attracting and cleaning the generated debris.

[0031] One end of the base 1 is fixedly connected to a support slide column 2, and the support slide column 2 is slidingly arranged with the inner wall of the support slide plate 3. The upper end of the support slide column 2 is fixedly provided with a hydraulic cylinder 5, and the output end of the hydraulic cylinder 5 is arranged on the support slide plate 3.

[0032] like Figure 1 As shown, the support slide column 2 supports and fixes the hydraulic cylinder 5. When the output end of the hydraulic cylinder 5 works, it can drive the support slide plate 3 to slide up and down along the support slide column 2, thereby adjusting the drilling depth of the drill rod 37 on the gear 6.

[0033] A fixing frame 35 is disposed at the lower end of the supporting slide plate 3 , and pulleys 36 are respectively disposed at both ends of the fixing frame 35 and are slidably connected to both ends of the supporting slide column 2 .

[0034] like Figure 7 As shown, the fixing frame 35 supports and fixes the pulley 36 , and the pulleys 36 are respectively arranged at both ends of the supporting slide column 2 , thereby limiting and assisting the sliding of the supporting slide plate 3 .

[0035] The magnetic component includes a magnet 26 , and the surface of the magnet 26 is smooth.

[0036] like Figure 8 As shown, the magnet 26 is used to absorb the generated metal debris, and the smooth surface can facilitate the removal of all the metal debris.

[0037] The working process of the present invention is as follows: when the present invention is in use, the gear 6 is placed above the first L-shaped block 7. When the output end of the hydraulic cylinder 5 works, the support slide plate 3 can be driven to slide along the support slide column 2 to limit the upper and lower positions. The support slide plate 3 drives the drill rod 37 to move downward, and the drill rod 37 presses the gear 6 downward. When the gear 6 above the first L-shaped block 7 is compressed, the sleeve rod 14 at the lower end of the sliding bracket 11 slides downward along the inner wall of the sleeve 13, and the first spring 10 shrinks under pressure. At the same time, since the pivot point of one end of the support rod 9 is fixed, the support rod 9 at the upper end of the base 1 deflects inwardly toward each other. When the support rod 9 deflects downward synchronously, since the length of the support rod 9 is fixed, the first L-shaped block 7 and the second L-shaped block 8 can be driven to move along the inner wall of the sliding bracket 11 to center the gear 6 above the first L-shaped block 7.

[0038] When the first tooth block 15 and the second tooth block 16 are directly opposite to the tooth groove of the gear 6, the two are fitted and directly placed in the tooth groove. When the first tooth block 15 and the second gear 18 at the other position are opposite to the protruding sawtooth of the gear 6, the first tooth block 15 and the second tooth block 16 are synchronously swung to both sides and placed in the adjacent tooth grooves on both sides of the sawtooth to fix the gear 6. When the first tooth block 15 and the second tooth block 16 are synchronously swung to both sides, they respectively drive the first rotating rod 24 and the second rotating rod 23 to rotate. The first rotating rod 24 and the second rotating rod 23 respectively drive the first gear 19 and the second gear 18 to rotate. When the first gear 19 rotates, it can drive the spur rack 17 to slide. The spur rack 17 drives the sliding column 21 to slide along the inner wall of the sliding shaft block 20, and the second spring 22 is compressed. Therefore, by setting the openable and closable first tooth block 15 and the second tooth block 16, a better fixing effect can be achieved for gears 6 with different numbers of teeth.

[0039] The gear 6 has different requirements on the rotation speed of the drill rod 37 due to the material, size, aperture, etc. The different rotation speeds of the drill rod 37 generate different ranges of metal debris. Therefore, in order to achieve better cleaning efficiency for the metal debris, the electric telescopic rod 30 can be controlled to work, and the electric telescopic rod 30 drives the fixed rod 27 to move toward each other, and the fixed rod 27 drives the pins 28 at both ends to move downward respectively. When the pins 28 slide in the slide groove 34 along the first swing rod 25 and the second swing rod 29, since one end of the first swing rod 25 and the second swing rod 29 is rotatably set on the fixed collar 32, when the pins 28 slide in the slide groove 34 along the first swing rod 25 and the second swing rod 29, the angle between the first swing rod 25 and the second swing rod 29 can be changed, thereby changing the distance between the magnetic component and the drill rod 37, ensuring that the magnetic component has a better attraction and cleaning effect on the generated debris.

[0040] The motor 4 works, and the output shaft of the motor 4 drives the fixed collar 32 and the mounting column 33 to rotate, and the mounting column 33 drives the drill rod 37 to rotate to drill the gear 6, and the fixed collar 32 drives the first swing arm 25 and the second swing arm 29 to rotate in a circle. The first swing arm 25 and the second swing arm 29 drive the magnetic components to rotate in a circle to form an annular magnetic range, which attracts and cleans the metal debris scattered from the drilling, and the cleaning effect is better. The number of magnetic components on the circumference of the mounting column 33 can be set according to needs.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
