Description

Technical Field

[0001] The invention belongs to the technical field of worm gear reducer manufacturing, and in particular relates to a drilling device for manufacturing worm gear reducers. Background Art

[0002] A worm gear reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque.

[0003] During the manufacturing process of the worm gear reducer, it is necessary to drill holes on the surface of the shell for subsequent assembly. However, the existing worm gear reducer still has significant defects when drilling holes. 1. The worm gear reducer is a relatively closed shell, and at the same time, a through hole for installing the worm gear is opened on its surface. At this time, when drilling holes on the reducer surface, debris and impurities generated will enter the reducer through the through hole, affecting subsequent assembly and use; 2. The existing drilling device generally only fixes the bottom of the reducer, and the fixing method is generally bolt fixing, which is more troublesome when disassembling and fixing the reducer, affecting the working drilling efficiency.

[0004] Therefore, we propose a drilling device for manufacturing worm gear reducers to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0033] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1 - Figure 10As shown in the figure, a drilling device for manufacturing a worm and worm gear reducer includes a processing box 1. Inside the left side of the processing box 1, there is a pushing mechanism 2. The pushing mechanism 2 includes a U-shaped moving seat 201. The U-shaped moving seat 201 is slidably installed inside the processing box 1. On the left side wall of the U-shaped moving seat 201, there is a hydraulic cylinder 202, and the hydraulic cylinder 202 is arranged on the left outer wall of the processing box 1. There are two hydraulic cylinders 202, so that the U-shaped moving seat 201 can move horizontally left and right more smoothly. At the same time, the two hydraulic cylinders 202 are controlled by one controller, so that the two hydraulic cylinders 202 can be started simultaneously, and then drive the U-shaped moving seat 201 to move. Inside the lower right side of the U-shaped moving seat 201, there is a rotary motor 203. On the power output end of the rotary motor 203, there is a first spur gear 204. The right side of the first spur gear 204 is meshed and connected with a second spur gear 205. The second spur gear 205 is rotatably installed on the U-shaped moving seat 201 through a first rotating shaft 206. At the upper end of the first rotating shaft 206, there is a placing table 207, so that the placing table 207 can rotate inside the U-shaped moving seat 201 through the first rotating shaft 206. Inside the upper right side of the U-shaped moving seat 201, an installation box 210 is rotatably installed through a second rotating shaft 209. On the lower surface of the placing table 207, there is a first annular rotating support plate 208, and the lower end of the first annular rotating support plate 208 is rotatably installed inside the lower right side of the U-shaped moving seat 201. The first annular rotating support plate 208 can support the placing table 207 while not affecting the rotation of the placing table 207, and improve the stability of the placing table 207. On the upper surface of the installation box 210, there is a second annular rotating support plate 211, and the upper end of the second annular rotating support plate 211 is rotatably installed inside the upper right side of the U-shaped moving seat 201. The cross-sections of the second rotating shaft 209 and the second annular rotating support plate 211 are T-shaped and L-shaped respectively. The settings of the second rotating shaft 209 and the second annular rotating support plate 211 with special shapes can stably install the installation box 210 inside the upper end of the U-shaped moving seat 201, and at the same time, do not affect the rotation of the installation box 210;

[0035] Inside the pushing mechanism 2, there are a clamping and fixing mechanism 3, an adjusting mechanism 4 and a rotating mechanism 5. The clamping and fixing mechanism 3 includes a double-shaft motor 301, and there are two double-shaft motors 301. The two double-shaft motors 301 are respectively arranged in the middle inside the placing table 207 and the installation box 210. On the power output ends of the two double-shaft motors 301, there are first threaded rods 302. On the circumferential surfaces of the four first threaded rods 302, there are moving blocks 303. Here, the two double-shaft motors 301 are controlled by the same controller, so that the two double-shaft motors 301 can be started simultaneously, and then drive the four first threaded rods 302 to rotate simultaneously. On the sides of the four moving blocks 303 away from the double-shaft motors 301, there are U-shaped moving plates 304. The four U-shaped moving plates 304 are fixedly connected with vertical plates 306 through connecting plates 305. The four vertical plates 306 are respectively arranged at the left and right ends of the front and back sides of the reducer housing 6;

[0036] It should be noted that the setting of the U-shaped movable plate 304 enables the inner ends of the front and rear sides of the U-shaped movable plate 304 to be connected to the movable block 303, and then when the movable block 303 drives the U-shaped movable plate 304 to move horizontally left and right, the U-shaped movable plate 304 will not hit the threaded rod 302 and the outer wall of the placement table 207, so that the U-shaped movable plate 304 can smoothly drive the vertical plate 306 to move horizontally through the connecting plate 305.

[0037] The adjusting mechanism 4 and the rotating mechanism 5 are both provided with four groups. The adjusting mechanism 4 includes a threaded rod 2 401. A worm 1 404 is provided at the upper end of the threaded rod 2 401. The right side of the worm 1 404 is meshed with a worm wheel 1 405. A worm 2 406 is provided in the middle of the worm wheel 1 405. The left side of the rear end of the worm 2 406 is meshed with a worm wheel 2 407. The lower end of the worm wheel 2 407 is provided with a threaded rod 3 408. The circumferential surfaces of the threaded rod 2 401 and the threaded rod 3 408 are both threadedly connected with a lifting block 409. An L-shaped limit is fixedly installed between the two lifting blocks 409 through a connecting plate 2 410. The positioning plate 411, the second threaded rod 401 and the third threaded rod 408 are all rotatably mounted on the surface of the vertical plate 306 through the fixing block 402, the front and rear ends of the second worm gear 406 are rotatably mounted inside the vertical plate 306, the circumferential surface of the upper end of the second threaded rod 401 is provided with a knob 403, and the four groups of adjustment mechanisms 4 are respectively arranged on the upper and lower sides between the two vertical plates 306 on the left and the upper and lower sides between the two vertical plates 306 on the right. The two upper L-shaped limiting plates 411 abut against the left and right sides of the upper end of the reducer housing 6, and the two lower L-shaped limiting plates 411 abut against the left and right sides of the lower end of the reducer housing 6;

[0038] It should be noted that by rotating the threaded rod 2401, the L-shaped limit plate 411 can be moved downward, and then the lower surface of the protruding end of the L-shaped limit plate 411 will contact the surface of the reducer housing 6, and then the clamping and fixing mechanism 3 will work, so that the vertical plates 306 are close to each other, and then the four L-shaped limit plates 411 are respectively abutted against the upper and lower ends on the left and right sides of the reducer housing 6, fixing the reducer housing 6 on the placement table 207, and at the same time, the fixing effects on the upper and lower sides are the same, and the upper part of the reducer housing 6 will not be affected. The shaking affects the drilling effect, and because of the worm gear transmission set in the adjusting mechanism 4, when the L-shaped limit plate 411 is subjected to the reverse action of the reducer housing 6, the L-shaped limit plate 411 cannot drive the threaded rod 2 401 and the threaded rod 3 408 to rotate in the opposite direction, which further improves the fixing effect of the L-shaped limit plate 411, and the four groups of L-shaped limit plates 411 will not block the drilling position around the worm gear mounting groove 7 in the reducer housing 6, that is, when the reducer housing 6 is fixed, it will not affect the drilling work.

[0039] The rotating mechanism 5 includes a telescopic cylinder 501, the telescopic end of the telescopic cylinder 501 is hinged with a mounting rod 503 through a hinge shaft, and a circular sealing block 504 is rotatably installed on the side of the mounting rod 503 away from the telescopic cylinder 501. The upper surface of the placement table 207 is placed with a reducer housing 6, and the left and right sides of the upper part and the front and rear sides of the lower part of the reducer housing 6 are provided with worm gear mounting grooves 7. Four circular sealing blocks 504 are respectively inserted into the inside of the four worm gear mounting grooves 7. The telescopic cylinder 501 is arranged inside the vertical plate 306, and an arc-shaped mounting plate 502 is provided on one side of the vertical plate 306, and an arc-shaped sliding groove 506 is provided on one side of the arc-shaped mounting plate 502. A slider is provided on the side wall of the mounting rod 503 close to one end of the telescopic cylinder 501 505, the slider 505 is slidably installed in the interior of the arc-shaped slide groove 506. The setting of the arc-shaped slide groove 506 provides space for the slider 505 to move, so that the slider 505 can move inside the arc-shaped slide groove 506. Among them, the side of the circular sealing block 504 close to the reducer housing 6 is made of soft materials such as rubber or sponge, so that the circular sealing blocks 504 on the front and rear sides will not be blocked by the protruding parts of the reducer housing 6 before they move laterally to the concentric axes of the worm gear mounting grooves 7 on the front and rear sides. The circular sealing blocks 504 can move smoothly to the worm gear mounting groove 7, and then return to the initial state according to the characteristics of the circular sealing block 504 at this section, thereby closing the worm gear mounting groove 7;

[0040] It should be noted that after the circular sealing block 504 is inserted into the inside of the worm gear mounting groove 7 and sealed, it can prevent the debris generated during drilling from entering the inside of the reducer housing 6 through the worm gear mounting groove 7, affecting the subsequent use of the reducer housing 6. At this time, the circular sealing block 504 will have a certain limiting effect. Then, when it is necessary to drill a hole on the surface of the reducer housing 6 on the path of the mounting rod 503, it is only necessary to start the telescopic cylinder 501, and the telescopic cylinder 501 drives the mounting rod 503 to move. Because the circular sealing block 504 has a positioning effect at this time, when the telescopic cylinder 501 pushes the mounting rod 503 to move, the mounting rod 503 will rotate with the circular sealing block 504 as the center of the circle, and rotate on the path of the arc-shaped slide groove 506 through the slider 505, so that the mounting rod 503 leaves the initial position, and the reducer housing 6 can be drilled.

[0041] A drilling mechanism 8 is provided inside the right side of the processing box 1. The drilling mechanism 8 includes a square mounting plate 801, and the square mounting plate 801 is fixedly installed on the right side of the processing box 1 by bolts, so that the drilling mechanism 8 can be disassembled as a whole, which is convenient for maintenance of the drilling mechanism 8. A stepper motor 802 is provided on the inner bottom wall of the square mounting plate 801, and a spur gear three 803 is provided at the power output end of the stepper motor 802. A spur gear four 804 is provided on the left side of the spur gear three 803, and a threaded rod four 805 is provided in the middle of the spur gear four 804. The circumferential surface of the threaded rod four 805 is threadedly connected to a lifting sealing plate 806. A drilling device 807 is slidably installed on the left side wall of the lifting sealing plate 806 through a movable block. The drilling device 807 is a prior art and will not be described in detail. A water spray pipe 808 is provided above the drilling device 807, which can be used for drilling. The coolant is sprayed out at the same time to cool the drill bit and wash away the generated debris to prevent the debris from floating around and affecting the work. The rear end of the lifting sealing plate 806 is provided with an electric cylinder 9, and the telescopic end of the electric cylinder 9 is connected to the rear side wall of the drilling device 807. The setting of the electric cylinder 9 can push the drilling device 807 to move horizontally back and forth, so that the drilling device 807 can drill more positions on the surface of the reducer housing 6. The upper and lower sides of the lifting sealing plate 806 are provided with U-shaped lifting plates 809. The left and right sides of the interior of the U-shaped lifting plate 809 are in contact with the upper and lower ends of the left side of the square mounting plate 801. The setting of the U-shaped lifting plate 809 can always close the lifting groove on the left side of the square mounting plate 801 without affecting the vertical movement of the lifting sealing plate 806, so as to prevent the lifting groove from being exposed, so that the debris generated during drilling enters the lifting groove and affects the use effect of the internal parts.

[0042] It should be noted that sealed doors are hingedly provided on the front and rear sides of the processing box 1. In order to observe the internal structure of the processing box 1 more intuitively, the sealed door in front of the processing box 1 is not drawn in the figure. Therefore, when the reducer housing 6 is placed in the processing box 1 for drilling processing, the processing box 1 is closed by the sealed door to prevent debris and impurities from floating in the working environment and polluting the working environment. Also not drawn in the figure are the diversion drainage groove on the right bottom plate of the processing box 1 and the drainage port at the right rear end, which can discharge the coolant and debris impurities out of the box through the diversion drainage groove and the drainage port.

[0043] When the present invention is in use, first, the reducer housing 6 to be drilled is placed on the placing table 207 inside the processing box 1. Then, the second threaded rod 401 is rotated by the knob 403. The rotation of the second threaded rod 401 drives the first worm 404 to rotate. The rotation of the first worm 404 drives the first worm gear 405 and the second worm 406 to rotate. The rotation of the second worm 406 drives the second worm gear 407 and the third threaded rod 408 to rotate. The simultaneous rotation of the second threaded rod 401 and the third threaded rod 408 can drive the lifting block 409, the second connecting plate 410, and the L-shaped limiting plate 411 to move vertically downward, so that the lower surface of the protruding end of the L-shaped limiting plate 411 abuts against the end of the reducer housing 6. Then, the other three adjusting mechanisms 4 are rotated, so that the four L-shaped limiting plates 411 respectively abut against the upper surfaces at the four corners of the reducer housing 6;

[0044] Start the two double-shaft motors 301. The double-shaft motors 301 drive the first threaded rod 302 to rotate, so that the moving block 303, the U-shaped moving plate 304, the first connecting plate 305, and the vertical plate 306 move towards the reducer housing 6. The vertical plate 306 also drives the L-shaped limiting plate 411 to move towards the reducer housing 6 at the same time, so that the vertical surface of the L-shaped limiting plate 411 abuts against the surface of the reducer housing 6, thereby fixing the reducer housing 6 on the placing table 207. At the same time, the vertical plate 306 will also drive the four circular sealing blocks 504 to move at the same time, and insert the four circular sealing blocks 504 into the four worm gear and worm mounting grooves 7 respectively to close the worm gear and worm mounting grooves 7. At this time, the placement and fixing work of the reducer housing 6 is completed;

[0045] Start the hydraulic cylinder 202 and the drilling device 807. The hydraulic cylinder 202 works to drive the U-shaped moving seat 201 to move horizontally to the right, and then带动 the reducer housing 6 to approach the drilling device 807, so that the drilling device 807 drills the surface of the reducer housing 6. By starting the stepping motor 802, the stepping motor 802 drives the fourth straight gear 804 and the fourth threaded rod 805 to rotate through the third straight gear 803, and then带动 the lifting and sealing plate 806 and the drilling device 807 to move vertically. By starting the electric cylinder 9, the drilling device 807 can be带动 to move horizontally back and forth on the lifting and sealing plate 806, so that the drilling device 807 can drill a certain area on the right side of the reducer housing 6;

[0046] Start the rotating motor 203, which drives the spur gear 2 205 and the rotating shaft 1 206 to rotate through the spur gear 1 204, so that the rotating shaft 1 206 drives the placement table 207 to rotate, and the placement table 207 drives the installation box 210, the clamping and fixing mechanism 3, the adjustment mechanism 4, the rotating mechanism 5 and the reducer housing 6 to rotate horizontally. After rotating ninety degrees counterclockwise, the front of the original reducer housing 6 can be rotated to the right for punching. Then continue to rotate ninety degrees counterclockwise to rotate the left side of the original reducer housing 6 to the right for punching. When it is necessary to punch a hole on the back side of the reducer housing 6, it is necessary to rotate one hundred and eighty degrees clockwise. After the degree is reset, rotate it clockwise ninety degrees to punch holes on the back side. This rotation method is because a dual-axis motor 301 is provided inside the placement table 207 and the installation box 210. In order to avoid the wires of the dual-axis motor 301 from being entangled, the placement table 207 cannot rotate more than one hundred and eighty degrees in one direction. Then, after the drilling of the surface of the reducer housing 6 is completed, the dual-axis motor 301 works to drive the vertical plate 306 away from the reducer housing 6, so that the L-shaped limit plate 411 no longer contacts the reducer housing 6. After losing the clamping and fixing effect on the reducer housing 6, the reducer housing 6 can be taken out from the inside of the processing box 1 for subsequent use.
