Description

Technical Field

[0001] This invention relates to the field of gearbox machining technology, specifically a gearbox drilling and positioning device. Background Technology

[0002] A gearbox is a transmission tool whose functions include: acceleration and deceleration (commonly known as a gearbox); changing the direction of transmission, for example, using two bevel gears to transmit force perpendicularly to another rotating shaft; changing the torque; under the same power conditions, the faster the gear rotates, the smaller the torque on the shaft, and vice versa; clutch function, such as a brake clutch; and power distribution, such as enabling one engine to drive multiple loads.

[0003] In the machining of gearboxes, the prototype or some parts of the gearbox need to be drilled to install the gear shaft. In modern production, drilling of gearboxes is usually done on an assembly line. Workpieces are conveyed to the drilling device at equal intervals, automatically positioned, and then drilled. However, placing the workpieces on the conveyor line is still usually done manually. Assembly line workers need to manually position the workpieces in the correct position so that the drilling surface is aligned with the drilling machine before placing them on the conveyor line. This machining method is still relatively labor-intensive, reduces production efficiency, and manual placement introduces a certain degree of error.

[0004] Therefore, in order to solve the above-mentioned technical problems in the prior art, a gear shaft box drilling positioning device is proposed. Summary of the Invention

[0029] The present invention has the following beneficial effects:

[0030] 1. This gearbox drilling positioning device, during the final positioning and drilling process where the workpiece is conveyed to the drilling device by the roller conveyor, utilizes multiple pre-positioning steps to place any workpiece stacked on the roller conveyor into the correct position where the required drilling surface faces the drilling device and is clamped by the first positioning mechanism. Therefore, during the loading process, manual workpiece alignment is unnecessary, reducing labor costs, improving production efficiency, and minimizing errors caused by manual placement.

[0031] 2. This gearbox drilling and positioning device, during the conveying process, first addresses the possibility of rectangular block workpieces having vertical length, width, or height surfaces. For workpieces in one of these situations, it tilts the workpiece onto the roller conveyor, changing it to one of the other two placement states. Then, through the cooperation of the roller conveyor and multiple baffles, and by pushing and rotating one side of the workpiece, the workpiece is eventually positioned horizontally or slightly tilted in one direction. Finally, two clamping plates in the second positioning mechanism first freely rotate in one direction to fit against the left and right inclined surfaces of the workpiece, and then rotate in opposite directions to a horizontal position, placing the workpiece horizontally.

[0032] 3. In the last positioning process before the gearbox drilling positioning device is conveyed to the first positioning mechanism, the height of the horizontally placed workpiece is first detected. If the workpiece is not facing the correct surface of the drilling device, it is clamped and rotated to ensure that the workpiece is finally correctly positioned. Attached Figure Description

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0046] Example 1

[0047] To achieve the positioning and drilling of workpiece 100 without relying on manual placement of workpiece 100 onto roller conveyor 210, instead relying on manual or automatic mechanical unloading to arbitrarily stack workpiece 100 onto roller conveyor 210, the positioning of workpiece 100 can be automatically completed. Example 1 is proposed.

[0048] Please see Figures 1-11 A gearbox drilling and positioning device includes a worktable 200, on which a roller conveying device 210, a drilling device 300 and a first positioning mechanism 400 are provided. The roller conveying device 210 is used to convey a workpiece 100, and the first positioning mechanism 400 is used to fix the workpiece 100 so that the drilling device 300 can drill holes in the workpiece 100.

[0049] Two second positioning mechanisms 500 are symmetrically arranged on the worktable 200 for correcting the tilted workpiece 100. The second positioning mechanism 500 includes a second cylinder 510 arranged on the worktable 200. A first mounting seat 520 is arranged on the piston rod of the second cylinder 510. A slide block 530 is slidably arranged in the first mounting seat 520. A rotating shaft 540 is rotatably arranged on the slide block 530. A clamping plate 550 is arranged on the rotating shaft 540.

[0050] The two clamps 550 are rotated and attached to the two ends of the inclined workpiece 100, and then rotated in opposite directions to adjust the workpiece 100 to a horizontal position.

[0051] The first positioning mechanism 400 includes two first cylinders 410 symmetrically arranged on the worktable 200, and a first clamp 420 is provided on the piston rod of each of the two first cylinders 410.

[0052] The second positioning mechanism 500 also includes a return spring 560 disposed in the first mounting base 520, with the two ends of the return spring 560 connected to the slide 530 and the inner wall of the first mounting base 520, respectively.

[0053] The first mounting base 520 has a gathering groove 570, which is funnel-shaped with its opening facing the clamping plate 550.

[0054] The second positioning mechanism 500 also includes a first stop component 590 disposed on the worktable 200, the first stop component 590 being located between the clamping plate 550 and the first positioning mechanism 400;

[0055] The first stop assembly 590 includes a third cylinder 591 disposed on the worktable 200, and a baffle 592 is disposed on the piston rod of the third cylinder 591.

[0056] In this embodiment: workpiece 100 represents the prototype or part of the gearbox during the machining process, specifically determined by the various machining methods of the gearbox, and the most conventional rectangular block-shaped workpiece 100 is selected as an example. Figure 11 As shown, the workpiece 100 in state c1 is in the correct orientation. Here, the x-plane is the front, the y-plane is the side, and the z-plane is the top. At this time, the z-plane is the plane that needs to be aligned with the drilling device 300. The workpiece 100 as a whole should be kept horizontal so that it can be held by the two first clamps 420.

[0057] First, as shown in the figure, the workpiece 100, which is placed at an angle, is blocked when it reaches the position of the baffle 592. At this time, the roller conveyor 210 continues to operate. Through the friction of multiple rollers below the workpiece 100, the workpiece 100 can gradually approach the rear end face of the baffle 592, thereby straightening the workpiece 100.

[0058] Furthermore, a second positioning mechanism 500 is provided to assist in aligning the workpiece 100. Two second cylinders 510 operate simultaneously, causing the two clamping plates 550 to approach the workpiece 100. Since the two clamping plates 550 can rotate freely, they will respectively abut against the left and right inclined surfaces of the workpiece 100. Then, the two second cylinders 510 drive the two clamping plates 550 to continue moving towards the center. At this time, as the clamping plates 550 slide relative to the converging groove 570 until they slide into the converging groove 570, under the constraint of the funnel-shaped opening of the converging groove 570, when the semi-circular end of the clamping plate 550 slides through the funnel-shaped opening and finally enters the rectangular segment of the converging groove 570, the rectangular segment fits with the end of the clamping plate 550, thus gradually aligning the clamping plate 550 to a horizontal position during this process. The workpiece 100, clamped by the two clamping plates 550, slides relative to them, thereby being aligned to a horizontal position. The return spring 560 serves to support the position of the slide block 530 when the second cylinder 510 does not further drive the clamping plate 550 closer to the workpiece 100.

[0059] Then, the third cylinder 591 drives the baffle 592 to rise to make way for the workpiece 100. The workpiece 100 stops at the first clamp 420 under the conveying of the roller conveyor 210. After the two first cylinders 410 drive the two first clamps 420 to hold the workpiece 100, the drilling device 300 drills holes in the workpiece 100.

[0060] It should be noted that the roller conveyor 210 can be driven by a motor to operate multiple rollers. As conventional technical means, the specific structure and working principle of the roller conveyor 210 and the drilling device 300 will not be described in detail.

[0061] Example 2

[0062] Since the two clamping plates 550 can rotate freely away from the gathering groove 570, they can better fit on the left and right sides of the workpiece 100. Therefore, it is necessary to ensure that the left clamping plate 550 rotates clockwise first and then counterclockwise back, and the right clamping plate 550 rotates counterclockwise first and then clockwise back. To ensure the accuracy of the rotation process, Embodiment 2 is proposed.

[0063] This embodiment is an improvement upon Embodiment 1. For details, please refer to [link / reference]. Figures 2-11 The second positioning mechanism 500 also includes two limiting components 580 symmetrically arranged in the first mounting base 520. The two limiting components 580 are used to restrict the clamping plate 550 from rotating unidirectionally toward the end face of the workpiece 100 when the slide 530 is not displaced relative to the first mounting base 520, and to restrict the clamping plate 550 from rotating unidirectionally in the opposite direction when the slide 530 is displaced relative to the first mounting base 520.

[0064] The limiting component 580 includes a turntable 581, on which two pawls 582 are rotatably mounted, a ratchet 584 is mounted on a rotating shaft 540, and two spring plates 583 are also mounted on the turntable 581.

[0065] The teeth of the two ratchet wheels 584 are in opposite directions, and in the lower limiting assembly 580, the ratchet wheel 584 is engaged with both pawls 582, while in the upper limiting assembly 580, the ratchet wheel 584 is disengaged from the two pawls 582.

[0066] The limiting assembly 580 also includes a transmission rod 585 disposed on the rotating shaft 540, a non-transmission groove 586 and a transmission groove 587 connected in the turntable 581, a guide groove 588 disposed in the first mounting base 520, and the turntable 581 is slidably connected in the guide groove 588.

[0067] In the lower limiting assembly 580, the transmission rod 585 is located in the non-transmission groove 586, while in the upper limiting assembly 580, the transmission rod 585 is located in the transmission groove 587.

[0068] In this embodiment, taking the two limiting components 580 on the left as an example, the two limiting components 580 on the right are completely mirror-symmetrical. The teeth of the two ratchet wheels 584 mounted on the rotating shaft 540 are opposite in direction. When the slide 530 is in the rightmost position relative to the first mounting seat 520 under the support of the return spring 560, the two turntables 581 are respectively located at the rightmost position of the two guide grooves 588, which are Z-shaped. At this time, the lower ratchet wheel 584 engages with the two lower pawls 582, while the upper ratchet wheel 584 is located above and does not contact the two upper pawls 582.

[0069] At this time, after the clamping plate 550 contacts the end point of the workpiece 100, it can only rotate clockwise under the limiting action of the lower limiting component 580. At this time, the lower ratchet 584 does not jam with the lower pawl 582, and the pawl 582 is continuously moved by the ratchet 584 under the elastic force of the spring plate 583.

[0070] When the second cylinder 510 further pushes the first mounting seat 520, the slide 530 moves to the left relative to the first mounting seat 520 due to the resistance of the workpiece 100 itself. At this time, the two turntables 581 slide to the left of the two guide grooves 588 respectively, and the positions of the two turntables 581 drop.

[0071] At this point, the upper ratchet 584 engages with the two upper pawls 582, while the lower ratchet 584 does not contact the two lower pawls 582. Under the limiting action of the upper limiting component 580, the rotating shaft 540 can only drive the clamping plate 550 to rotate counterclockwise, thereby causing the workpiece 100 to be aligned.

[0072] Furthermore, to ensure that the pawl 582 maintains a good engagement with the ratchet 584 and does not jam when the turntable 581 moves up and down relative to the ratchet 584, transmission rods 585 are installed at both the upper and lower ends of the rotating shaft 540. The non-transmission groove 586 is located on the upper side of the turntable 581, while the transmission groove 587 is located on the lower side, with a smooth transition between them. The positions of the transmission groove 587 and the non-transmission groove 586 on the lower side are reversed. The non-transmission groove 586 is larger than the transmission rod 585, and the transmission groove 587 fits into the polygonal transmission rod 585.

[0073] When turntable 581 is located on the right side of guide groove 588, shaft 540 rotates. The lower transmission rod 585 will not drive the lower turntable 581 to rotate. Although the upper turntable 581 is disengaged from ratchet 584 and will not limit shaft 540, it will rotate under the drive of shaft 540. Therefore, when turntable 581 slides to the left side of guide groove 588, the upper turntable 581 descends, and the pawl 582 on it will not get stuck with ratchet 584.

[0074] The same applies to the lower turntable 581. At this time, the lower turntable 581 disengages from the ratchet 584 and does not obstruct the counterclockwise rotation of the shaft 540, but it will maintain synchronous rotation with the shaft 540.

[0075] It should be noted that the above working principle is based on the premise that the workpiece is held at 100°. Figure 11 In state c2 or b2, if the workpiece 100 is in state c1 or b1, the two clamping plates 550 will not rotate, but will only keep the workpiece 100 in a straight position under the drive of the second cylinder 510.

[0076] Example 3

[0077] To place the workpiece 100 in the center on the roller conveyor 210 to facilitate the operation of the second positioning mechanism 500, Embodiment 3 is proposed;

[0078] This embodiment is an improvement upon embodiment 2. For details, please refer to [link / reference]. Figures 2-11 The workbench 200 is also equipped with a third positioning mechanism 600 for positioning the workpiece 100 in the middle of the roller conveyor 210. The third positioning mechanism 600 is located behind the second positioning mechanism 500.

[0079] The third positioning mechanism 600 includes two fourth cylinders 610 symmetrically arranged on the worktable 200, and each of the piston rods of the two fourth cylinders 610 is provided with a push plate 620.

[0080] The third positioning mechanism 600 also includes a second stop component 630 disposed between the push plate 620 and the second positioning mechanism 500. The structure of the second stop component 630 is the same as that of the first stop component 590.

[0081] In this embodiment: when the workpiece 100 is conveyed to the second stopping component 630, the workpiece 100 is stopped by the second stopping component 630, and the roller conveyor 210 continues to run, so that the workpiece 100 tends to be aligned. At this time, the two fourth cylinders 610 drive the two push plates 620 to move towards the middle, so that the workpiece 100 can be placed in the middle position.

[0082] It should be noted that a force sensor can be installed on the push plate 620. When the two fourth cylinders 610 push the two push plates 620 and the reaction force from the workpiece 100 reaches a certain level, the fourth cylinders 610 are controlled to stop running to avoid damaging the workpiece 100.

[0083] Example 4

[0084] like Figure 11 As shown, the actual placement posture of the workpiece 100 may be b1, b2, b3, b4, c1, c2, c3, c4. In order to enable all workpieces 100 to reach the state of b1, b2 or c1, c2, so as to facilitate the operation of the second positioning mechanism 500, embodiment 4 is proposed.

[0085] This embodiment is an improvement upon embodiment 3. For details, please refer to [link / reference]. Figures 2-11 The workbench 200 is also equipped with a fourth positioning mechanism 700, which is located behind the third positioning mechanism 600.

[0086] The fourth positioning mechanism 700 includes two limiting plates 710 and a fifth cylinder 720 disposed on the worktable 200. A push rod 730 is disposed on the piston rod of the fifth cylinder 720.

[0087] The fourth positioning mechanism 700 also includes a third stop component 740 disposed between the limit plate 710 and the third positioning mechanism 600. The structure of the third stop component 740 is the same as that of the first stop component 590.

[0088] In this embodiment: when c1 or b1 stops in front of the third stopping component 740, the fifth cylinder 720 drives the push rod 730 to move to the left without contacting the workpiece 100. The workpiece 100 in states c2 and b2 will be touched by the push rod 730 and tend to be leveled. The workpiece 100 in states c3, c4 and b3, b4 will be pushed by the push rod 730 to contact the left limiting plate 710, and then pushed by the push rod 730 to rotate to states c2 and b2.

[0089] Example 5

[0090] Workpiece 100 may also have placement orientations a1, a2, a3, and a4;

[0091] This embodiment is an improvement upon embodiment 4. For details, please refer to [link / reference]. Figures 1-11 The workbench 200 is also equipped with a baffle 220 and a fourth stop assembly 800. The fourth stop assembly 800 is located behind the fourth positioning mechanism 700, and the baffle 220 is located behind the fourth stop assembly 800.

[0092] The fourth stop component 800 has the same structure as the first stop component 590.

[0093] In this embodiment: before entering the workbench 200, the b1, b2, b3, b4, c1, c2, c3, and c4 can pass through due to the obstruction of the baffle 220, while a1, a2, a3, and a4 will be pushed down by the baffle 220 and pass through in the state of b1, b2, b3, b4, c1, c2, c3, and c4.

[0094] By using the equally spaced reciprocating lifting and lowering of the fourth stopping component 800, several workpieces 100 are stopped behind the fourth stopping component 800 and pass through one by one. Here, a limiter track can be added to the front side of the fourth stopping component 800 so that only one workpiece 100 can pass through at a time.

[0095] Example 6

[0096] The horizontal workpiece 100 placed by the second positioning mechanism 500 may be in state c1 or b1. In order to rotate the workpiece 100 in state b1 to state c1, embodiment 6 is proposed.

[0097] This embodiment is an improvement upon embodiment 5. For details, please refer to [link / reference]. Figures 2-11 The worktable 200 is also provided with a fifth positioning mechanism 900, which is located between the second positioning mechanism 500 and the drilling device 300. The fifth positioning mechanism 900 includes a slide rod 910 that is slidably disposed on the worktable 200. The worktable 200 is also provided with a pressure sensor 920.

[0098] Two sixth cylinders 930 are symmetrically arranged on the worktable 200. A second mounting seat 940 is provided on the piston rod of each of the two sixth cylinders 930. A motor 950 is provided inside each of the two second mounting seats 940. A second clamp 960 is provided on the output shaft of each of the two motors 950.

[0099] In this embodiment: when the workpiece 100 in state b1 passes through the slide bar 910, it will be pushed upward and contact the pressure sensor 920. At this time, the pressure sensor 920 can control the roller conveyor 210 to stop when the workpiece 100 is conveyed to the position of the second clamp 960 through an electrical signal. After the two sixth cylinders 930 drive the two second clamps 960 to hold the workpiece 100, the two motors 950 drive the workpiece 100 to rotate to state c1.
