[0050] The involute bevel gear assembly position adjustment tool 10 proposed in the present invention is a tool for adjusting the assembly position of involute bevel gears that has a simple structure, is easy to adjust, and is time-saving and effective. It aims to overcome the problem that the axial and radial assembly position steps of gears in the prior art are complicated and difficult to adjust, and replaces the traditional method of manually adjusting the assembly position of involute bevel gears, thereby improving the adjustment efficiency.

[0051] like Figures 2 to 5 As shown, the mounting base 100 is an I-shaped structure. The mounting base 100 is located below the pinion ball screw mechanism 400 and the pinion gear box 500, and the mounting base 100 is located on one side of the large gear ball screw mechanism 200. The mounting base 100 is mainly used to install and locate the position of the pinion ball screw mechanism 400 and the position of the large gear ball screw mechanism 200.

[0052] In this embodiment, the mounting base 100 is connected to the first positioning mounting plate 210 of the large gear ball screw mechanism 200 through the connecting member 110. Specifically, the connecting member 110 is a right-angle connecting block, which is respectively connected to the bottom plate of the mounting base 100 and the first positioning mounting plate 210 of the large gear ball screw mechanism 200 through bolts. In this way, the connection by bolts can facilitate assembly and subsequent disassembly and maintenance.

[0053] like Figure 2 , Figure 3 , Figure 6 , Figure 7 as well as Figure 8As shown, the large gear ball screw mechanism 200 includes a first positioning mounting plate 210, a first slide plate 220, a first linear guide rail 230 and a first ball screw 240. The first positioning mounting plate 210 is connected to one side of the mounting base 100. The first linear guide rail 230 and the first ball screw 240 are respectively located between the first positioning mounting plate 210 and the first slide plate 220. The first slide plate 220 is slidingly connected to the first positioning mounting plate 210 through the first linear guide rail 230. The first ball screw 240 is arranged on the first positioning mounting plate 210. The first slide plate 220 is connected to the slider 241 of the first ball screw 240.

[0054] like Figure 2 , Figure 3 , Fig. 9 as well as Fig.10 As shown, the large gear offset adjustment mechanism 300 includes a gear mounting seat 310, a movable block 320 and a lifting bolt 330. The bottom of the gear mounting seat 310 is connected to the first slide plate 220. The movable block 320 is used to install and fix the large gear 20. The movable block 320 is slidably set on the gear mounting seat 310. The lifting bolt 330 is screwed into and penetrates the gear mounting seat 310 and is screwed to the movable block 320.

[0055] like Figure 2 , Figure 3 , Fig.11 as well as Fig.12 As shown, the pinion ball screw mechanism 400 includes a second positioning mounting plate 410, a second slide plate 420, a second linear guide rail 430 and a second ball screw 440. The second positioning mounting plate 410 is installed on the mounting base 100 and the second positioning mounting plate 410 is adjacent to the first positioning mounting plate 210. The second linear guide rail 430 and the second ball screw 440 are respectively located between the second positioning mounting plate 410 and the second slide plate 420. The second slide plate 420 is slidably connected to the second positioning mounting plate 410 through the second linear guide rail 430. The second ball screw 440 is arranged on the second positioning mounting plate 410. The second slide plate 420 is connected to the slider 441 of the second ball screw 440.

[0056] like Figure 2 , Figure 3 As shown in FIG. 13 , the bottom of the small gear box 500 is connected to the second slide plate 420 . The small gear box 500 is used to install and fix the small gear 30 . The small gear box 500 is arranged adjacent to the gear mounting seat 310 so that the small gear on the small gear box 500 and the large gear on the gear mounting seat 310 are meshed and assembled with each other.

[0057] The above-mentioned arc bevel gear assembly position adjustment tool 10 relatively installs and fixes the first positioning mounting plate 210 and the second positioning mounting plate 410 through the mounting base 100 to form a stable and firm assembly position adjustment tool platform. The large gear is installed on the gear mounting seat 310 through the movable block 320. Since the movable block 320 is slidably arranged on the gear mounting seat 310, the lifting bolt 330 is screwed into the gear mounting seat 310 on the one hand, and on the other hand, it passes through the gear mounting seat 310 and is screwed with the movable block 320, so that when the lifting bolt 330 is turned clockwise, the movable block 320 is lifted, and when the lifting bolt 330 is turned counterclockwise, the movable block 320 is lowered, thereby adjusting the position of the large gear in the radial direction, that is, adjusting the offset distance of the large gear. The position of the gear mounting seat 310 can be adjusted along the sliding direction of the first linear guide 230 through the first ball screw 240, thereby adjusting the position of the large gear in the axial direction. Similarly, the pinion ball screw mechanism 400 is also implemented in the axial direction, and the position of the pinion gear box 500 can be adjusted along the sliding direction of the second linear guide 430 through the second ball screw 440, thereby adjusting the position of the pinion gear in the axial direction, so that the pinion gear 30 on the pinion gear box 500 and the large gear 20 on the gear mounting seat 310 are meshed and assembled with each other, and the adjustment can be repeated multiple times to make the assembly position of the pinion gear and the large gear of the spiral bevel gear structure accurate. The above-mentioned spiral bevel gear assembly position adjustment tool has a simple structure, convenient adjustment, time-saving and high efficiency.

[0058] Please refer again Figures 6 to 8 In one embodiment, the gear ball screw mechanism 200 further includes a plurality of fixing grooves 250, and the plurality of fixing grooves 250 are arranged on the first positioning mounting plate 210 at equal intervals. Figure 3 As shown, the first slide plate 220 is slidably abutted against the top of each fixing groove 250. The fixing grooves 250 support the first slide plate 220 and share the pressure of the first linear guide rail 230. Figure 3 As shown, on the other hand, when the gear mounting seat 310 is connected to the first positioning mounting plate 210, it is often connected and fixed by a fastening bolt. At this time, the screw portion of the fastening bolt can be avoided in the fixing groove 250. In this way, by reasonably arranging the spacing of each fixing groove 250 and designing the mounting screw hole at the bottom of the gear mounting seat 310 to correspond to the corresponding fixing groove 250, a better avoidance of the fastening bolt can be achieved, so that the gear mounting seat 310 can be better and stably connected to the first positioning mounting plate 210.

[0059] Furthermore, the large gear ball screw mechanism 200 further includes a first adjustment wrench 260, a first measuring piece 270 and a first scale 280. The first adjustment wrench 260 is connected to the first ball screw 240, and the first adjustment wrench 260 is used to drive the first ball screw 240 to rotate. The first scale 280 is mounted on the side of the first positioning mounting plate 210, and one end of the first measuring piece 270 is mounted on the side of the first slide 220, and the other end is located above the scale of the first scale 280. In this way, when the first slide 220 moves, the first measuring piece 270 moves relative to the first scale 280, so that the moving distance of the first slide 220 can be known.

[0060] It can be understood that the large gear ball screw mechanism includes the first slide plate 220, the fixing groove 250, the first linear guide rail 230, the first ball screw 240, the first adjustment wrench 260, the first measuring piece 270, the first scale 280, the first positioning mounting plate 210 and other parts. The fixing groove 250, the first linear guide rail 230, and the first ball screw 240 are installed on the first positioning mounting plate 210 through a connecting member, and the first slide plate 220 is connected to the fixing groove 250 by a fastening bolt. When a person turns the first adjustment wrench 260, the circular motion of the first ball screw 240 is converted into the linear motion of the first slide plate 220, thereby realizing the change of the axial displacement of the large gear.

[0061] like Fig. 9 , Fig.10 , Figures 14 to 17 As shown, in one embodiment, the gear mounting seat 310 has a mounting notch 311, the movable block 320 covers the mounting notch 311, and the movable block 320 is provided with a large gear mounting opening 321, which is used to penetrate the large gear 20 mounted on the movable block 320, that is, the large gear 20 is mounted on the movable block 320 and penetrates the large gear mounting opening 321. In one embodiment, the gear mounting seat 310 has a mounting plane 312 and a debugging plane 313, the mounting plane 312 and the debugging plane 313 are arranged opposite to each other, wherein the debugging plane 313 faces the pinion 30. The movable block 320 includes a mounting layer 322, a movable layer 323, and a limiting ring 324 which are integrally formed, the mounting layer 322 is located on one side of the mounting plane 312 and abuts against the mounting plane 312, the movable layer 323 is located in the mounting notch 311, the limiting ring 324 is located on one side of the debugging plane 313, and the limiting ring 324 is used to limit and abut against the large gear 20.

[0062] Please refer again Fig.11 and Fig.12 In one embodiment, the pinion ball screw mechanism 400 further includes a plurality of limit grooves 450, and the plurality of limit grooves 450 are arranged on the second positioning mounting plate 410 at equal intervals. Figure 2 and Figure 3 As shown, the second slide plate 420 is slidably abutted against the top of each limiting groove 450. The limiting grooves 450 play a role in supporting the second slide plate 420 and sharing the pressure of the second linear guide rail 430; Figure 3 As shown, on the other hand, when the pinion gear box 500 is connected to the second positioning mounting plate 410, it is often connected and fixed by a fastening bolt. At this time, the screw rod part of the fastening bolt can be avoided in the limiting groove 450. In this way, by reasonably arranging the spacing of each limiting groove 450 and designing the mounting screw hole at the bottom of the pinion gear box 500 to correspond to the corresponding limiting groove 450, a better avoidance of the fastening bolt can be achieved, so that the pinion gear box 500 can be stably connected to the second positioning mounting plate 410.

[0063] Furthermore, the pinion ball screw mechanism 400 further includes a second adjustment wrench 460, a second measuring piece 470 and a second scale 480. The second adjustment wrench 460 is connected to the second ball screw 440, and the second adjustment wrench 460 is used to drive the second ball screw 440 to rotate. The second scale 480 is mounted on the side of the second positioning mounting plate 410, and one end of the second measuring piece 470 is mounted on the side of the second slide 420, and the other end is located above the scale of the second scale 480. In this way, when the second slide 420 moves, the second measuring piece 470 moves relative to the second scale 480, so that the moving distance of the second slide 420 can be known.

[0064] It can be understood that the pinion ball screw mechanism includes the second slide plate 420, the second positioning mounting plate 410, the second ball screw 440, the second measuring piece 470, the second scale 480, the limit groove 450, the second linear guide 430, the second adjustment wrench 460 and other parts. The limit groove 450, the second linear guide 430, and the second ball screw 440 are installed on the second positioning mounting plate 410 through a connecting member, and the second slide plate 420 is connected to the limit groove 450 through a fastening bolt. A person turns the second adjustment wrench 460 to convert the circular motion of the second ball screw 440 into the linear motion of the second slide plate 420, thereby realizing the change of the axial displacement of the pinion.

[0065] like Fig.18 , Fig.19 as well as Fig. 20As shown, in order to achieve precise adjustment of the assembly position, in one embodiment, the spiral bevel gear assembly position adjustment tool further includes a laser distance measurement mechanism 600, and the laser distance measurement mechanism 600 includes an X-axis laser distance measurement sensor 610, a Y-axis laser distance measurement sensor 620, and a Z-axis laser distance measurement sensor 630. The X-axis laser distance measurement sensor 610 is used to measure the actual displacement of the small end face of the small gear 30 when adjusting the axial distance of the small gear 30. The Y-axis laser distance measurement sensor 620 is used to measure the actual displacement of the small end face of the large gear 20 when adjusting the axial distance of the large gear 20. The Z-axis laser distance measurement sensor 630 is used to measure the actual displacement of the offset distance of the large gear 20 when adjusting the large gear 20.

[0066] To facilitate assembly and debugging, in one embodiment, the laser distance measuring mechanism 600 further includes a distance measuring bracket 640, which is disposed adjacent to the mounting base 100, and the X-axis laser distance measuring sensor 610 and the Y-axis laser distance measuring sensor 620 are disposed on the distance measuring bracket 640. Furthermore, the distance measuring bracket 640 can also be connected to the mounting base 100 through a connector, so that the integrity of the entire tooling equipment can be achieved.

[0067] In one embodiment, the probe of the X-axis laser ranging sensor 610 faces the small end face of the pinion gear 30. In one embodiment, the probe of the Y-axis laser ranging sensor 620 faces the small end face of the large gear 20. It should be noted that the pinion gear 30 and the large gear 20 are both spiral bevel gears. Due to the particularity of their structure, according to the principle of cone, the spiral bevel gear has a large end and a small end, and the surface where the pinion gear 30 and the large gear 20 contact each other is the end face of the small end.

[0068] Furthermore, in one embodiment, the spiral bevel gear assembly position adjustment tool further includes a visual inspection mechanism 700, which is disposed on the distance measuring bracket 640, and is used to detect the contact marks between the tooth surface of the large gear 20 and the tooth surface of the small gear 30. The visual inspection mechanism 700 is also electrically connected to the computer equipment in the background, and is used to send the data of the contact marks collected and detected to the background computer for automatic program analysis, and the background computer analyzes the image features of the contact marks, and solves the assembly position adjustment parameters, so that the operator can adjust the large gear ball screw mechanism 200, the large gear offset adjustment mechanism 300 and the small gear ball screw mechanism 400 according to the assembly position adjustment parameters. The adjustment is completed until the actual tooth surface contact mark meets the optimal solution calculated by the program.

[0069] In one embodiment, the visual inspection mechanism 700 includes a light source 710 and an industrial camera 720, which are respectively mounted on the distance measuring bracket 640, and the light source 710 is directed toward the contact area between the tooth surface of the large gear 20 and the tooth surface of the small gear 30, and the lens of the industrial camera 720 is directed toward the contact area. In this way, the contact mark of the tooth surface is accurately detected with the cooperation of the light source 710 and the industrial camera 720.

[0070] It can be understood that the spiral bevel gear assembly position adjustment tool is equipped with an automatic detection mechanism, which includes a visual detection mechanism 700 and a laser distance measurement mechanism 600. The laser distance measurement mechanism 600 includes an X-axis laser distance measurement sensor 610, a Y-axis laser distance measurement sensor 620, a Z-axis laser distance measurement sensor 630 and other components. The X-axis laser distance measurement sensor 610 is used to measure the actual displacement of the small end face when adjusting the axial distance of the small gear, and can also record the vertical change of the small end face of the tested gear relative to the rotating axis; it should be noted that the rotating axis refers to the rotating axis of the tested gear. In this embodiment, it should be the rotating axis of the small gear. The purpose of recording the change is because the axial adjustment is completed by turning the hand wheel and observing the scale coefficient. The laser displacement sensor will record the actual displacement change of the small end face of the tested gear, and determine whether the manual adjustment is accurate based on the change, thereby forming a closed-loop control of the adjustment amount based on the laser sensor and the scale. The Y-axis laser ranging sensor 620 is used to measure the actual displacement of the small end face when adjusting the axial distance of the large gear, and can also record the change in the verticality of the small end face of the tested gear relative to the rotating axis. Similarly, it should be noted that the rotating axis refers to the rotating axis of the tested gear. In this embodiment, it should be the rotating axis of the large gear. The Z-axis laser ranging sensor 630 is installed in the top area of ​​the gear mounting seat 310, and is used to measure the actual displacement of adjusting the offset distance of the large gear, and can also record the circular runout of the rotating axis of the tested gear. The purpose of recording the circular runout is because the offset distance adjustment is completed by adding a gasket of a certain thickness. The laser displacement sensor will record the actual radial displacement change of the tested gear shaft, and determine whether the thickness of the manually added gasket is accurate based on the change, thereby forming a closed-loop control of the adjustment amount based on the laser sensor and the adjustment gasket. The visual inspection mechanism 700 includes components such as a light source 710 and an industrial camera 720 . The industrial camera 720 has a lens. Under the illumination of the light source 710 , the industrial camera 720 is used to accurately detect the contact marks on the tooth surface.

[0071] Furthermore, in one embodiment, the specific idea of ​​using the spiral bevel gear assembly position adjustment tooling of each of the above embodiments to complete the adjustment process is:

[0072] (1) Install the pinion and gear of the gear assembly to be inspected on the spiral bevel gear assembly position adjustment tooling equipment, and apply red lead on the tooth surfaces of the gears to be inspected, that is, apply red lead on the tooth surfaces of the pinion and gear;

[0073] (2) Start driving the gears to roll against each other. During the rolling process, the industrial camera 720 will take photos of the contact marks, and the laser distance measuring mechanism 600 will record the corresponding parameters;

[0074] (3) The background program automatically analyzes the contact mark image features and solves the assembly position adjustment parameters;

[0075] (4) The person uses the result as the preset adjustment amount and begins to use the tooling to adjust the assembly position;

[0076] (5) Repeat steps (2) to (4) until the actual tooth surface contact mark meets the optimal solution calculated by the program.

[0077] The adjustment process of the large and small gear axial and large gear offset positions of the spiral bevel gear assembly position adjustment tool of the present invention is described as follows:

[0078] The axial position adjustment method adopted in this scheme is a closed-loop control adjustment method based on a laser distance sensor and a scale. For the adjustment method of the axial position of the large gear: after the preset adjustment amount is known, it is necessary to first loosen the fastening bolts before adjustment, and then turn the adjustment wrench to drive the ball screw. At this time, the circular motion of the screw is converted into the horizontal motion of the slide along the linear guide direction. The axial displacement is given by observing the change in the reading of the measuring piece on the scale. At the same time, the laser distance sensor will measure the distance of the small end face of the large gear in real time, and make a difference between the actual displacement measured and the displacement given by turning the adjustment wrench. The difference is used as the second preset adjustment amount, and the adjustment wrench is turned again to start the second adjustment. This cycle is repeated until the actual displacement measured is equal to the preset adjustment amount, and then the fastening bolts are re-tightened. The adjustment method for the axial position of the small gear is the same as the above process.

[0079] The offset distance position adjustment method adopted in this scheme is a closed-loop control adjustment method based on a combination of a ranging laser sensor and a standard specification gasket. For the offset distance position adjustment method of the large gear: after the preset adjustment amount is known, it is necessary to first loosen the fastening bolts and turn the lifting bolts before adjustment. At this time, a gap will be generated between the movable block and the mounting surface of the mounting seat. Secondly, a person manually adds an adjustment gasket of a certain specification to the gap, and turns the lifting bolts again to lower the movable block and press it with the adjustment gasket. At the same time, the Z-axis laser ranging sensor 630 will measure the axial cylindrical surface of the large gear in real time, and subtract the actual displacement measured from the thickness of the adjustment gasket added by the person, and use the difference as the second preset adjustment amount. Turn the lifting screw again to start the second adjustment, and repeat this cycle until the actual displacement measured is equal to the preset adjustment amount, and then re-tighten the fastening bolts.

[0080] It can be understood that the above-mentioned embodiments of the present invention are based on the idea of ​​precise adjustment of the axial assembly position of the closed-loop bevel gear based on the ranging laser sensor and the scale, and the idea of ​​using the adjustment hand wheel to drive the ball screw mechanism to achieve the change of the axial adjustment amount of the bevel gear. These two ideas are helpful for understanding the creation of the present invention, and are also the innovative points of the creation of the present invention that stand out from the prior art.

[0081] In summary, the advantages of various embodiments of the present invention are:

[0082] 1) The adjustment device has a simple and reliable structure, and the bevel gear offset and axial position adjustment are highly efficient;

[0083] 2) Use industrial camera 720 to obtain contact mark images to make contact mark identification more accurate;

[0084] 3) Flexible measurement accuracy: the accuracy of the adjustment amount can be changed by changing the accuracy of the scale and laser ranging sensor;

[0085] 4) Save labor costs.

[0086] At the same time, the present invention has been proven to be feasible through experiments, simulations, and use, and the equipment construction has been completed with good results. The present invention can be used to build similar spiral bevel gear test bench scenarios.

[0087] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
