Description

Technical Field

[0001] The present invention relates to the technical field of gear shaft box processing, and more particularly to a gear shaft box body processing positioning device. Background Art

[0002] Gearboxes are an essential component of mechanical transmission systems. Their primary function is to transmit power from the input to the output through a series of gears and shafts. Because gearboxes must withstand high loads and operate at high speeds, their machining demands high precision and quality.

[0003] There are many processing steps in the gear shaft box. Among them, in the rough machining milling step, the milling machine needs to perform multi-angle processing on the gear shaft box to process the required holes, slots, etc. There are usually through holes on the surface of the gear shaft box. These holes are called bearing seat holes, which are used to install bearings, gear shafts and other components. Some bearing seat holes pass through the gear shaft box horizontally or vertically, and some bearing seat holes pass through the gear shaft box at an angle. When the gear shaft box has both straight bearing seat holes and inclined bearing seat holes, the processing requirements and processing costs of the milling machine will increase significantly. When processing existing gear boxes with straight and inclined bearing seat holes, if you don’t want to adjust the angle of the drill bit, you must adjust the placement angle of the workpiece. In most cases, the angle adjustment of the workpiece requires manual control of the positioning device and change of the positioning method. This makes the processing efficiency of gear shaft boxes with multiple bearing seat holes low, time-consuming and manpower-consuming, and the precision error is large. Therefore, it is necessary to propose a gear shaft box body processing positioning device to solve the above problems. Summary of the Invention

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. When processing bearing seat holes with different inclination angles, the cutter head can be used to reach the corresponding height, and the U-shaped rod can be pushed to the appropriate height by the push rod. Then, the U-shaped rod can be driven to slide toward the inside of the workbench during the feeding process of the processing mechanism, squeezing and lifting the inclined plane block to raise the support column, thereby driving the support plate to rotate, and then the workpiece mechanism installed on the top of the support plate can be tilted synchronously. The originally inclined bearing seat hole on the box can be transformed into a horizontal hole, which is convenient for the cutter head processing. Moreover, the U-shaped rod can still support the inclined plane block after lifting the inclined plane block, avoiding the shaking and falling of the positioning mechanism during the cutter head processing of the inclined hole, improving the overall stability and ensuring the processing accuracy.

[0019] 2. Due to the large size and heavy weight of the workpiece mechanism, the pressure on the shaft block at the rotation point of the base and the support plate is enormous, and it is very easy to be damaged after long-term use. Therefore, a buffer mechanism is installed on the top surface of the workbench, below the support plate, which can buffer the reset of the support plate, reduce the impact, and make the support plate reset smoothly, reducing the pressure on the shaft block. Taking advantage of the different volumes of different box models, the number of turns of the screw is different, so that the lifting plate descends to different heights, the degree of compression of the pressure rod on the lifting frame is different, and the depth of the closing plate entering the partition is different. The number of through-holes closed by the closing plate is different. When the piston squeezes the hydraulic oil in the buffer chamber, the flow of hydraulic oil through the through-holes changes, and finally the damping strength of the buffer mechanism changes to adapt to the corresponding box model, thereby better reducing the impact force on the workpiece mechanism.

[0020] 3. The rotation of the support plate can also drive the connecting rod to swing, and the connecting rod drives the slide bar to descend. The slide bar pulls the cleaning motor down through the adjustment frame and the connecting arm, so that the brush head reaches the position where it can clean the corresponding bearing seat hole, and then through the cooperation of the traveling gear and the rack, the brush head is brought close to the workpiece mechanism for cleaning operation.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0034] For example 1, please refer to Figures 1 to 10As shown, the present invention discloses a gear shaft box processing and positioning device, including a support mechanism 1, the support mechanism 1 includes a workbench 11, a first slide groove 12 is provided at one end of the top of the workbench 11, two support columns 17 are symmetrically installed inside the workbench 11, the top of the support column 17 is provided with an adjustment groove 18, and an inclined block 19 is fixed on the inner side of the support column 17;

A support rod 25 and a U-shaped rod 26 are slidably connected to the interior of the cabinet 21. The support rod 25 and the U-shaped rod 26 are fixed vertically.

[0036] A positioning mechanism 3 is mounted on the top surface of the workbench 11. The positioning mechanism 3 includes a base 31 and a support plate 32 mounted on the top surface of the workbench 11. A plurality of shaft blocks 33 are equidistantly mounted on one end of the bottom surface of the support plate 32. The shaft blocks 33 are rotatably connected to the top surface of the base 31. Two sliding buttons 34 are symmetrically mounted on the other end of the bottom surface of the support plate 32. The sliding buttons 34 are slidably connected to the corresponding adjustment slots 18. A plurality of positioning heads 393 are symmetrically provided on the top surface of the support plate 32.

[0037] The workpiece mechanism 4 is mounted on the top surface of the support plate 32 . The workpiece mechanism 4 includes a box body 41 mounted on the top surface of the support plate 32 . A plurality of positioning holes 44 are provided at the bottom of the box body 41 . The positioning heads 393 are engaged and connected in the corresponding positioning holes 44 .

[0038] The support mechanism 1 also includes a first electric push rod 13 installed inside the first slide groove 12. The output end of the first electric push rod 13 is installed on the bottom side of the cabinet 21. A second slide groove 14 is provided at the other end of the top surface of the workbench 11. Two racks 15 are symmetrically installed in the second slide groove 14. Two first springs 16 are symmetrically installed inside the workbench 11. The support column 17 is elastically connected to the inside of the workbench 11 through the first spring 16.

[0039] The processing mechanism 2 also includes a second electric push rod 23 installed inside the lifting groove 22, and a cutter head 24 is installed at the output end of the second electric push rod 23. Two second springs 27 are symmetrically installed inside the cabinet 21, and the support rod 25 and the U-shaped rod 26 are elastically connected to the inside of the cabinet 21 through the second springs 27.

[0040] The positioning mechanism 3 also includes two positioning arms 35 symmetrically installed on the top surface of the support plate 32. The top of the positioning arm 35 is threadedly connected to a screw 36, and the bottom surface of the screw 36 is rotatably connected to a pressure plate 37. The pressure plate 37 contacts the top surface of the box body 41. The interior of the positioning arm 35 is slidably connected to a lifting plate 38, and the lifting plate 38 is threadedly connected to the screw 36. A lifting frame 39 is fixed to the outside of the lifting plate 38. The lifting frame 39 is slidably connected to the inside of the support plate 32 and the positioning arm 35, and the bottom of the lifting frame 39 passes through the bottom surface of the support plate 32. A pressure rod 391 is fixed to the bottom end of the lifting frame 39, and a magnet 392 is installed on the side surface of the bottom end of the pressure rod 391.

[0041] The workpiece mechanism 4 further includes a straight hole 42 and an oblique hole 43 provided on the box body 41 .

[0042] In the initial state, the support plate 32 is placed horizontally, and the support column 17 is connected to the slide button 34 through the adjustment slot 18; under the elastic force of the second spring 27, the support rod 25 and the U-shaped rod 26 are in the highest position, that is, the front end of the U-shaped rod 26 is above the inclined block 19.

[0043] The worker places the box 41 on the top surface of the support plate 32. The positioning holes 44 on the bottom surface of the box 41 and the positioning heads 393 on the top surface of the support plate 32 are engaged with each other, which can not only accurately locate the position of the box 41, but also play a preliminary fixation role to reduce the shaking of the box 41. After the box 41 is positioned, it will be between the two positioning arms 35. The worker turns the screw 36, and the screw 36 drives the pressure plate 37 to descend toward the top surface of the box 41, so that the pressure plate 37 presses the box 41, further stabilizing the workpiece mechanism 4, and preventing the box 41 from shifting, shaking, and other problems during the processing. Start the second electric push rod 23, which drives the cutter head 24 to slide in the lifting groove 22, thereby adjusting the position of the cutter head 24 (so that the cutter head 24 is aligned with the processing position of the straight hole 42. In this solution, the straight hole 42 is processed first by default), and then start the first electric push rod 13. The first electric push rod 13 pushes the cabinet body 21 to slide in the first slide groove 12, so that the cabinet body 21 approaches the box body 41, thereby processing the straight hole 42 on the box body 41. During the sliding process of the cabinet body 21 in the first slide groove 12, the U-shaped rod 26 will be driven to slide into the interior of the workbench 11. Since the U-shaped rod 26 is above the inclined block 19, it will not conflict with the inclined block 19, so the support column 17 will not move.

[0044] When the inclined hole 43 on the box body 41 needs to be processed (the inclined hole 43 is inclined at a certain angle and penetrates the box body 41. Since the cutter head 24 is a horizontal feed, if you want to process the inclined hole 43, you need to turn the inclined hole 43 into a horizontal state), first, the second electric push rod 23 drives the cutter head 24 to descend until the cutter head 24 descends to a height that can process the inclined hole 43. During this process, the cutter head 24 will contact and press down the push rod 25 at the bottom of the lifting slot 22, causing the push rod 25 to slide downward. The push rod 25 drives the U-shaped rod 26 to descend and compresses the second spring 27. The U-shaped rod 26 descends to the same height as the inclined block 19. As the first electric push rod 13 drives the cabinet 21 toward the box body 41, the cabinet 21 drives the U-shaped rod 26 to contact the inclined block 19. The side of the inclined block 19 is inclined, and the U-shaped rod 26 squeezes the inclined block 19 to lift it. The inclined block 19 drives the support column 17 upward, and the support column 17 stretches the first spring 16. The support column 17 lifts one side of the support plate 32, causing the shaft block 33 on the other side of the support plate 32 to rotate around the top of the base 31. At the same time, the slide button 34 slides in the adjustment slot 18. The support plate 32 causes the workpiece mechanism 4 on top of it to tilt until the inclined hole 43 becomes horizontal. After that, the processing mechanism 2 reaches the processing position and begins processing the inclined hole 43.

[0045] When the cabinet 21 drives the cutter head 24 to advance, the U-shaped rod 26 will always be at the bottom of the inclined plane block 19 after completing lifting the inclined plane block 19, thereby supporting the inclined plane block 19 and preventing the support column 17 and the inclined plane block 19 from falling, thereby ensuring that when the cutter head 24 processes the inclined hole 43, the support plate 32 keeps the inclined hole 43 in a horizontal state.

[0046] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10 The top surface of the workbench 11 is provided with a buffer mechanism 5, which includes a box body 51 installed on the top surface of the workbench 11. A buffer chamber 52 and two side chambers 54 are provided inside the box body 51. The bottom ends of the two side chambers 54 are communicated with both sides of the bottom end of the buffer chamber 52. A piston 53 and a third spring 55 are installed in the buffer chamber 52. The piston 53 is elastically connected to the buffer chamber 52 through the third spring 55, and the top end of the piston 53 contacts the bottom surface of the support plate 32. A partition 56 is installed in the buffer chamber 52, and a plurality of through holes 57 are provided on the partition 56. The box body 5 1 is installed inside. A closing plate 58 and a fourth spring 592 are fixed to the outer end of the closing plate 58. The closing plate 58 and the wedge 59 are elastically connected to the box body 51 through the fourth spring 592. The bottom end of the pressure rod 391 contacts the wedge 59. The top surface of the wedge 59 is provided with a plurality of grooves 591 at equal intervals. An inclined groove 593 is provided on the side of the box body 51. A fifth spring 594 and an iron block 595 are installed in the inclined groove 593. The iron block 595 is elastically connected to the inside of the inclined groove 593 through the fifth spring 594. A protrusion 596 is fixed to the bottom surface of the iron block 595.

[0047] From the perspective of processing efficiency, the various joints in the current milling equipment move very quickly, which can greatly shorten the adjustment time of positioning devices, cutting tools and other equipment, thereby improving processing efficiency. Since the workpiece mechanism 4 is generally large in size and heavy in mass, the support plate 32 needs to be reset after driving the workpiece mechanism 4 to tilt. During the resetting process, in order to reduce the rotational pressure of the shaft block 33 and reduce the vibration of the workpiece mechanism 4 and improve the service life of the mechanism, a buffer mechanism 5 is provided on the top surface of the workbench 11 and below the support plate 32. The top of the piston 53 always contacts the bottom surface of the support plate 32. When the support plate 32 tilts, the third spring 55 inside the buffer chamber 52 pushes the piston 53 to rise from the inside of the buffer chamber 52, so that the top of the piston 53 always contacts the support plate 32. During the rising process of the piston 53, the hydraulic oil in the two side chambers 54 will also flow into the buffer chamber 52 (the buffer chamber 52 is divided into two upper and lower chambers by the partition 56, the piston 53 and the third spring 55 are in the upper chamber, the bottom of the side chamber 54 is connected to the lower chamber of the buffer chamber 52, and the hydraulic oil in the side chamber 54 enters the upper chamber from the lower chamber through the through hole 57 of the partition 56). When the U-shaped rod 26 is reset, the inclined block 19 loses its support, and the weight of the workpiece mechanism 4 will cause the support plate 32 to reset immediately, thereby driving the support column 17 to reset immediately. If this series of resets is not buffered, the vibration and damage to the equipment and workpiece will be very large. Therefore, during the reset process of the support plate 32, the piston 53 will also be pushed to slide into the buffer chamber 52. The piston 53 compresses the third spring 55 and squeezes the hydraulic oil in the buffer chamber 52 into the side chamber 54. However, due to the limited aperture of the through hole 57, the flow of the hydraulic oil can be slowed down, thereby absorbing most of the impact in the above process, so that the support plate 32 can be reset smoothly, reducing the shaking of the equipment and the workpiece.

[0048] Different models of box bodies 41 have different volumes, and thus different impact forces on the positioning mechanism 3, thus requiring different buffering forces of the buffer mechanism 5. Therefore, the buffering forces of the buffer mechanism 5 need to be automatically adjusted according to the differences in the workpiece mechanism 4. The different volumes of the box body 41 can be directly reflected in the stroke of the screw 36 driving the pressure plate 37 to press the box body 41 (the number of turns of the screw 36 is different). For different models of box bodies 41, during the rotation of the screw 36, the screw 36 will also drive the lifting plate 38 to descend. The different number of turns of the screw 36 will result in different descending heights of the lifting plate 38. The lifting plate 38 will drive the pressure rod 391 to descend through the lifting frame 39. The descent of the pressure rod 391 will squeeze the wedge block 59. At the same time, the magnet 392 on the side of the pressure rod 391 drives the iron block 595 in the inclined slot 593 to slide outward. The iron block 595 stretches the fifth spring 594, causing the protrusion 596 at the bottom of the iron block 595 to lose its restriction on the closing plate 58, so that the pressure rod 391 squeezes the wedge block. 59, the wedge block 59 drives the closing plate 58 to push into the interior of the partition 56, so that the closing plate 58 closes a corresponding number of through holes 57, reducing the flow of hydraulic oil through the through holes 57 (a plurality of through holes 57 are provided on the partition 56, and the closing plate 58 can only close the through holes 57 in its own moving direction in turn. Therefore, even if the closing plate 58 penetrates into the partition 56 to the maximum extent, it will not close all the through holes 57, that is, the role of the closing plate 58 is to reduce or increase the number of open through holes 57, so as to change the flow of hydraulic oil in the buffer chamber 52 within a certain period of time, thereby absorbing the impact force and achieving a buffering effect), thereby improving the damping strength of the buffer mechanism 5, and compressing the fourth spring 592 during the sliding process of the wedge block 59 into the box body 51.

[0049] As the support plate 32 rotates via the shaft block 33, the pressure rod 391 simultaneously moves in a circular motion, moving away from the wedge 59 and the chute 593. The iron block 595 loses the influence of the magnet 392, and under the elastic force of the fifth spring 594, the protrusion 596 at the bottom of the iron block 595 immediately engages with the corresponding groove 591 on the top surface of the closing plate 58, preventing the closing plate 58 from sliding outward. When the pressure rod 391 rotates back in a circular motion, the magnet 392 again drives the iron block 595 outward, which again stretches the fifth spring 594 and disengages the protrusion 596 from the groove 591. However, at this point, the bottom of the pressure rod 391 abuts against the wedge 59, preventing the closing plate 58 from sliding outward from the partition 56. When the rotary screw 36 causes the lifting plate 38 to rise, thereby driving the pressure rod 391 to rise, since the pressure rod 391 separates before the wedge block 59 and the iron block 595 is always under the magnetic influence of the magnet 392, the closing plate 58 and the wedge block 59 are first ejected by the fourth spring 592, and the iron block 595 is reset later.

[0050] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 10An adjustment mechanism 6 is installed on the outside of the shaft block 33. The adjustment mechanism 6 includes two mounting rings 61 fixed to the outside of the shaft block 33. One end of a connecting rod 62 is installed in each mounting ring 61, and a mounting ring 61 is also installed on the other end of the connecting rod 62. The mounting ring 61 at the other end of each connecting rod 62 is rotatably connected to a sliding rod 63.

[0051] A cleaning mechanism 7 is installed in the second slide 14. The cleaning mechanism 7 includes a shell 71 whose bottom is slidably connected to the second slide 14. A main slide 72 is provided on the side of the shell 71 facing the box body 41. Side slides 73 are symmetrically provided on both sides of the shell 71. A cleaning motor 74 is slidably connected in the main slide 72. A brush head 75 is installed at the output end of the cleaning motor 74.

[0052] The workpiece mechanism 4 will generate a lot of debris during the processing, which needs to be cleaned in time. Therefore, a cleaning mechanism 7 is provided on the top surface of the workbench 11. In the initial stage, the brush head 75 is at the same height as the straight hole 42, which is convenient for cleaning the straight hole 42. When the cutter head 24 processes the inclined hole 43, the support plate 32 is tilted by the rotation of the shaft block 33, and the rotation of the shaft block 33 drives the mounting ring 61 on the outside of the shaft block 33 to rotate, thereby driving the connecting rod 62 to swing. The connecting rod 62 drives the slide bar 63 to swing through another set of mounting rings 61. The slide bar 63 slides with the adjustment frame 77. During the swinging process of the slide bar 63, the connecting arm 76 is pulled downward by the adjustment frame 77 and slides relative to the adjustment frame 77. The mounting ring 61 at the end of the slide bar 63 rotates relative to the slide bar 63. The connecting arm 76 slides in the side slide 73 and drives the cleaning motor 74 to descend, and the cleaning motor 74 drives the brush head 75 to descend, so that the brush head 75 reaches a position where it can clean the inclined hole 43, and then the traveling motor 78 inside the shell 71 drives the bevel gear 79 to rotate, and the bevel gear 79 drives the traveling gear 791 to rotate through the connecting shaft 792, and the traveling gear 791 engages with the rack 15, thereby driving the shell 71 in the second slide groove 14 to approach the workpiece mechanism 4, so that the brush head 75 hits the inclined hole 43, and then cleans the inclined hole 43.
