Description

Technical Field

[0001] This invention belongs to the field of worm gear reducer manufacturing technology, specifically a drilling device for manufacturing worm gear reducers. Background Technology

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

[0003] During the manufacturing process of worm gear reducers, drilling is required on the surface of the housing for subsequent assembly. However, existing drilling methods for worm gear reducers still have significant drawbacks: 1. Worm gear reducers are relatively enclosed housings, and their surfaces have through holes for mounting the worm gear. When drilling the reducer surface, debris and impurities generated can enter the reducer through these through holes, affecting subsequent assembly and use; 2. Existing drilling devices generally only fix the bottom of the reducer, and the fixing method is usually bolt fixing. This makes disassembly and reassembly of the reducer cumbersome and affects drilling efficiency.

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

[0005] The purpose of this invention is to address the problem that drilling holes in the housing surface of worm gear reducers is necessary during manufacturing for subsequent assembly. However, existing drilling methods for worm gear reducers have significant drawbacks. A worm gear reducer is a relatively enclosed housing, and its surface has through holes for mounting the worm gear. When drilling the reducer surface, debris and impurities can enter the reducer through these through holes, affecting subsequent assembly and use.

[0033] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1 - Figure 10As shown, a drilling device for manufacturing a worm gear reducer includes a machining box 1. A pushing mechanism 2 is disposed inside the left side of the machining box 1. The pushing mechanism 2 includes a U-shaped movable seat 201, which is slidably installed inside the machining box 1. A hydraulic cylinder 202 is disposed on the left side wall of the U-shaped movable seat 201, and the hydraulic cylinder 202 is disposed on the left outer wall of the machining box 1. Two hydraulic cylinders 202 are provided, allowing the U-shaped movable seat 201 to move more smoothly horizontally left and right. Simultaneously, the two hydraulic cylinders 202... 2. A controller is used to simultaneously activate two hydraulic cylinders 202, thereby moving the C-shaped movable seat 201. A rotary motor 203 is installed inside the lower right side of the C-shaped movable seat 201. A spur gear 204 is installed at the power output end of the rotary motor 203. A spur gear 205 is meshed with the right side of the spur gear 204. The spur gear 205 is rotatably mounted on the C-shaped movable seat 201 via a rotating shaft 206. A placement platform 207 is installed at the upper end of the rotating shaft 206, allowing the placement platform to... The placement platform 207 can rotate inside the U-shaped movable base 201 via a pivot 206. A mounting box 210 is rotatably mounted inside the upper right side of the U-shaped movable base 201 via a pivot 209. An annular rotating support plate 208 is provided on the lower surface of the placement platform 207, and the lower end of the annular rotating support plate 208 is rotatably mounted inside the lower right side of the U-shaped movable base 201. The annular rotating support plate 208 can support the placement platform 207 without affecting its rotation, thus raising the placement platform. To ensure the stability of the 207, the upper surface of the mounting box 210 is provided with an annular rotating support plate 211, and the upper end of the 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 rotating shaft 209 and the annular rotating support plate 211 are T-shaped and L-shaped, respectively. The special shape of the rotating shaft 209 and the annular rotating support plate 211 can stably install the mounting box 210 inside the upper end of the U-shaped moving seat 201 without affecting the rotation of the mounting box 210.

[0035] The pushing mechanism 2 is internally equipped with a clamping and fixing mechanism 3, an adjusting mechanism 4, and a rotating mechanism 5. The clamping and fixing mechanism 3 includes a dual-axis motor 301, and there are two dual-axis motors 301. The two dual-axis motors 301 are respectively located in the middle of the placement platform 207 and the mounting box 210. The power output end of the two dual-axis motors 301 is provided with a threaded rod 302. The circumferential surface of the four threaded rods 302 is provided with a moving block 303. The two dual-axis motors 301 are controlled by the same controller, so that the two dual-axis motors 301 can start at the same time, thereby driving the four threaded rods 302 to rotate at the same time. The side of the four moving blocks 303 away from the dual-axis motors 301 is provided with a U-shaped moving plate 304. The four U-shaped moving plates 304 are fixedly connected to a vertical plate 306 through a connecting plate 305. The four vertical plates 306 are respectively located at the left and right ends of the front and rear sides of the reducer housing 6.

[0036] It should be noted that the U-shaped movable plate 304 is designed so that the inner ends of the front and rear sides of the U-shaped movable plate 304 are connected to the movable block 303. As a result, 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 come into contact with the threaded rod 302 and the outer wall of the placement platform 207. This allows the U-shaped movable plate 304 to smoothly drive the vertical plate 306 to move horizontally through the connecting plate 305.

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

[0038] It should be noted that by rotating the threaded rod 401, the L-shaped limiting plate 411 can move downwards. Then, the lower surface of the protruding end of the L-shaped limiting plate 411 will contact the surface of the reducer housing 6. The clamping and fixing mechanism 3 then operates, causing the vertical plates 306 to move closer together. This results in the four L-shaped limiting plates 411 respectively abutting against the upper and lower ends of the left and right sides of the reducer housing 6, fixing the reducer housing 6 onto the placement platform 207. Simultaneously, the fixing effect on the upper and lower sides is the same, and the upper part of the reducer housing 6 will not shift. Shaking affects the drilling effect, and because of the worm gear transmission in the adjustment 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 401 and the threaded rod 408 to rotate in the opposite direction, which further improves the fixing effect of the L-shaped limit plate 411. In addition, the four sets 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, the drilling work is not affected.

[0039] The rotating mechanism 5 includes a telescopic cylinder 501. The telescopic end of the telescopic cylinder 501 is hinged to a mounting rod 503 via a hinge shaft. A circular sealing block 504 is rotatably mounted on the side of the mounting rod 503 away from the telescopic cylinder 501. A reducer housing 6 is placed on the upper surface of the placement platform 207. Worm gear mounting grooves 7 are provided on the left and right sides of the upper part and the front and rear sides of the lower part of the reducer housing 6. Four circular sealing blocks 504 are respectively inserted into the four worm gear mounting grooves 7. The telescopic cylinder 501 is located inside the vertical plate 306. 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 near the end of the telescopic cylinder 501. 505, the slider 505 is slidably installed inside the arc-shaped slide groove 506. The arc-shaped slide groove 506 provides the slider 505 with room to move, allowing the slider 505 to move inside the arc-shaped slide groove 506. The side of the circular sealing block 504 closest to the reducer housing 6 is made of soft material such as rubber or sponge. This ensures that the circular sealing blocks 504 on both the front and rear sides are not obstructed by the protruding parts of the reducer housing 6 before moving laterally to the concentric shaft of the worm gear mounting groove 7 on both the front and rear sides. This allows the circular sealing blocks 504 to move smoothly to the worm gear mounting groove 7. Afterwards, according to the characteristics of this section of the circular sealing block 504, it returns to its initial state, thereby closing the worm gear mounting groove 7.

[0040] It should be noted that after the circular sealing block 504 is inserted into the worm gear mounting groove 7 and seals it, it can prevent the debris generated during drilling from entering the reducer housing 6 through the worm gear mounting groove 7 and 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 along the path of the mounting rod 503, it is only necessary to start the telescopic cylinder 501. 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 around the circular sealing block 504 as the center. It will rotate along the path of the arc-shaped slide groove 506 through the slider 505, so that the mounting rod 503 leaves the initial position and can drill a hole in the reducer housing 6.

[0041] A drilling mechanism 8 is installed inside the right side of the processing box 1. The drilling mechanism 8 includes a square mounting plate 801, which is fixedly installed inside the right side of the processing box 1 by bolts, allowing the drilling mechanism 8 to be disassembled as a whole for easy maintenance. A stepper motor 802 is installed on the inner bottom wall of the square mounting plate 801. A spur gear 3 803 is installed at the power output end of the stepper motor 802. A spur gear 4 804 is installed on the left side of the spur gear 3 803. A threaded rod 4 805 is installed in the middle of the spur gear 4 804. A lifting sealing plate 806 is threadedly connected to the circumferential surface of the threaded rod 4 805. A drilling device 807 is slidably installed on the left side wall of the lifting sealing plate 806 via a movable block. The drilling device 807 is prior art and will not be described in detail. A water spray pipe 808 is installed above the drilling device 807, which can spray water to drill holes. Coolant is sprayed out to cool the drill bit and flush away the generated debris, preventing it from scattering around and affecting the work. An electric cylinder 9 is installed at the rear end of the lifting sealing plate 806, and the telescopic end of the electric cylinder 9 is connected to the rear side wall of the drilling equipment 807. The electric cylinder 9 can push the drilling equipment 807 to move horizontally back and forth, allowing the drilling equipment 807 to drill more positions on the surface of the reducer housing 6. U-shaped lifting plates 809 are provided on both the upper and lower sides of the lifting sealing plate 806. The left and right sides inside 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 U-shaped lifting plate 809 can keep the lifting groove on the left side of the square mounting plate 801 closed without affecting the vertical movement of the lifting sealing plate 806, preventing the lifting groove from being exposed and allowing the debris generated during drilling to enter the lifting groove and affect the use of the internal parts.

[0042] It should be noted that both the front and rear sides of the machining box 1 are hinged with sealed doors. To make the internal structure of the machining box 1 easier to observe, the front sealed door of the machining box 1 is not shown in the figure. Therefore, when the reducer housing 6 is placed inside the machining box 1 for drilling, the machining box 1 is closed by the sealed door to prevent debris and impurities from being scattered in the working environment and contaminating it. Also not shown in the figure are the drainage channel on the bottom right side of the machining box 1 and the drain outlet at the rear right side, which can discharge coolant and debris and impurities from the box through the drainage channel and the drain outlet.

[0043] When using this invention, firstly, the reducer housing 6 to be drilled is placed on the placement platform 207 inside the processing box 1. Then, the threaded rod 401 is rotated by the knob 403. The rotation of the threaded rod 401 drives the worm gear 404 to rotate. The rotation of the worm gear 404 drives the worm wheel 405 and the worm gear 406 to rotate. The rotation of the worm gear 406 drives the worm wheel 407 and the threaded rod 408 to rotate. The simultaneous rotation of the threaded rod 401 and the threaded rod 408 can drive the lifting block 409, the 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 adjustment mechanisms 4 are rotated so that the four sets of L-shaped limiting plates 411 abut against the upper surface of the four corners of the reducer housing 6 respectively.

[0044] Two dual-axis motors 301 are started. The dual-axis motors 301 drive the threaded rod 302 to rotate, causing the moving block 303, U-shaped moving plate 304, connecting plate 305 and vertical plate 306 to move towards the reducer housing 6. At the same time, the vertical plate 306 drives the L-shaped limiting plate 411 to move towards the reducer housing 6, 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 placement platform 207. At the same time, the vertical plate 306 also drives the four circular sealing blocks 504 to move, inserting the four circular sealing blocks 504 into the four worm gear mounting slots 7 respectively, sealing the worm gear mounting slots 7. At this time, the placement and fixing of the reducer housing 6 is completed.

[0045] Start the hydraulic cylinder 202 and the drilling equipment 807. The hydraulic cylinder 202 drives the U-shaped moving seat 201 to move horizontally to the right, which in turn drives the reducer housing 6 to approach the drilling equipment 807, so that the drilling equipment 807 can drill holes on the surface of the reducer housing 6. Start the stepper motor 802, which drives the spur gear 804 and the threaded rod 805 to rotate through the spur gear 3 803, which in turn drives the lifting sealing plate 806 and the drilling equipment 807 to move vertically. Start the electric cylinder 9, which can drive the drilling equipment 807 to move horizontally back and forth on the lifting sealing plate 806, so that the drilling equipment 807 can drill holes in a certain area on the right side of the reducer housing 6.

[0046] Start the rotary motor 203. The rotary motor 203 drives the spur gear 205 and the rotating shaft 206 to rotate via the spur gear 204. This causes the rotating shaft 206 to rotate the placement platform 207. The placement platform 207 then drives the mounting box 210, the clamping and fixing mechanism 3, the adjusting mechanism 4, the rotating mechanism 5, and the reducer housing 6 to rotate laterally. After rotating 90 degrees counterclockwise, the front of the reducer housing 6 can be rotated to the right for drilling. Then, continue rotating 90 degrees counterclockwise to rotate the left side of the reducer housing 6 to the right for drilling. When drilling is needed on the rear side of the reducer housing 6, it needs to be rotated 180 degrees clockwise. After resetting, rotate 90 degrees clockwise to drill holes on the rear side. This rotation method is because the placement platform 207 and the mounting box 210 are equipped with a dual-axis motor 301. To avoid the wires of the dual-axis motor 301 getting tangled, the placement platform 207 cannot rotate more than 180 degrees in one direction. After drilling holes on the surface of the reducer housing 6, the dual-axis motor 301 works, driving 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 processing box 1 for subsequent use.
