Detailed implementation mode

[0022] The following makes a detailed description of the specific implementation mode of the present invention in conjunction with the attached drawings.

[0023] Embodiment, as Figures 1-8 shown, the present invention provides a technical solution: a boring processing device for a planet carrier, including a base 8, a main body structure 1, a position-changing structure 2 and a limiting structure 3; the main body structure 1 is fixedly arranged in the middle of the upper wall at the left end of the base 8, the position-changing structure 2 is fixedly arranged at the rear end of the base 8, and the position-changing structure 2 is opposite to the main body structure 1, and the limiting structure 3 is fixedly arranged on the position-changing structure 2; the main body structure 1 is used for lifting and feeding during boring processing, and the position-changing structure 2 cooperates with the limiting structure 3 to realize automatic loading and unloading of the convex planet carrier and change the boring position during the boring processing of the planet carrier.

[0024] As a further solution of the present invention, the main body structure 1 includes a positioning plate 11, a lifting slide rail 12, a translational slide rail 13 and a boring machine main body 14; one end of the positioning plate 11 is vertically welded to the middle of the upper wall at the left end of the base 8, the lifting slide rail 12 is fixedly arranged in the middle of the right side wall of the positioning plate 11, the translational slide rail 13 is vertically arranged on the lifting slide rail 12, and the translational slide rail 13 moves up and down through the lifting slide rail 12, the boring machine main body 14 is fixedly arranged on the translational slide rail 13, and a boring tool is detachably arranged on the boring machine main body 14, and the boring machine main body 14 moves left and right through the translational slide rail 13; the lifting slide rail 12 drives the boring machine main body 14 to move up and down for feeding, the translational slide rail 13 drives the boring machine main body 14 to move left and right to adjust the position, and the boring machine main body 14 drives the boring tool to rotate for processing.

[0025] More specifically, through the orthogonal movement of the lifting slide rail 12 and the translational slide rail 13, the boring machine main body 14 has the ability of precise positioning in a two-dimensional plane, which can meet the boring requirements of multiple positions of the planet carrier.

[0026] As a further solution of the present invention, the transposition structure 2 includes a jib 21, a drive shaft 22, a first motor 23, a drive gear 24, a driven gear 25, and a transposition unit 26; the jib 21 is L-shaped, one end of the jib 21 is fixedly arranged on the upper wall at the rear end of the base 8, and the other end of the jib 21 is located above the translation slide rail 13. One end of the drive shaft 22 movably penetrates through the other end of the jib 21, and the drive shaft 22 can rotate. The first motor 23 is fixedly arranged on the lower wall at the other end of the jib 21 and is located behind the drive shaft 22. The drive gear 24 is fixedly arranged on the drive end of the first motor 23. The driven gear 25 is fixedly sleeved on the drive shaft 22, and the driven gear 25 meshes with the drive gear 24. The transposition unit 26 is fixedly arranged on the other end of the drive shaft 22 and is located below the boring machine main body 14. Driven by the first motor 23 on the jib 21, the drive gear 24 is driven to rotate and engage with the driven gear 25 to drive the drive shaft 22 to rotate, and then drive the transposition unit 26 to rotate.

[0027] More specifically, the transposition disk 261 is driven by the first motor 23 to rotate to meet the frequent transposition, loading, and unloading requirements during the processing of the planet carrier. Its service life is longer than that of flexible transmission methods such as belt transmission. The integrated design of the jib 21 and the base 8 enables the transposition structure 2 and the main body structure 1 to form a front-back dislocation layout in space, avoiding component interference and adapting to the layout requirements of medium and small-sized processing equipment.

[0028] As a further solution of the present invention, the transposition unit 26 includes a transposition disk 261, two pairs of adjustment seats 262, two pairs of adjustment bolts 263, two pairs of adjustment nuts 264, two pairs of second motors 265, and two pairs of transposition wheels 266; the transposition disk 261 is a circular structure, and two pairs of arc-shaped transposition ports 5 are equidistantly arranged on the side wall of the transposition disk 261. The transposition disk 261 is fixedly sleeved on the other end of the drive shaft 22, and the transposition port 5 can be opposite to the boring machine main body 14.

Two pairs of adjustment seats 262 are respectively movably embedded in the transposition slots 6.

Two pairs of adjustment nuts 264 are respectively movably embedded in the adjustment slot 7, and the adjustment nuts 264 are screwed with the adjustment bolts 263. Two pairs of second motors 265 are respectively fixedly arranged on the other ends of the adjustment seats 262. Two pairs of transposition wheels 266 are respectively fixedly arranged on the drive ends of the second motors 265, and the transposition wheels 266 can be located in the transposition slots 6. By rotating the transposition disk 261, the position of the transposition port 5 can be adjusted. Through the cooperation of the transposition port 5 and the first limiting ring 31, the planet carrier is driven to move for loading and transposition. By driving the transposition wheels 266 to rotate by the second motor 265, the planet carrier is driven to rotate by the engagement of the transposition wheels 266 with the tooth column part of the planet carrier to adjust the boring processing position.

[0029] More specifically, by adjusting the coordinated movement of the bolt 263 and the nut 264, it can be used for the transposition adjustment of the hole processing of planetary carriers of different specifications. The second motor 265 adopts a stepper motor or a servo motor, combined with precision gear transmission, to meet the multi-directional boring requirements of the planetary carrier. The rigid engagement transmission of the transposition wheel 266 and the tooth column of the planetary carrier avoids the slippage problem of traditional belt transmission.

[0030] As a further solution of the present invention, the limiting structure 3 includes a mounting rod 30, a first limiting ring 31, a mounting frame 32, a second limiting ring 33, a pair of guide arms 34, an intercepting arm 35, a third motor 36, a toggle arm 37, a pair of conveyor belt assemblies 38, a carrier frame 39 and a camera 40; one end of the mounting rod 30 is fixedly set on one end of the boom 21, the first limiting ring 31 is semi-annular, the first limiting ring 31 is fixedly set on the other end of the mounting rod 30, and the first limiting ring 31 is sleeved on the outside of the transposition disk 261, and the upper wall of the first limiting ring 31 is on the same as the upper wall of the transposition disk 261. On the horizontal plane, the mounting bracket 32 is concave, one end of the mounting bracket 32 is fixedly arranged on one end of the first limiting ring 31, the second limiting ring 33 is T-shaped, one end of the second limiting ring 33 is fixedly arranged on the other end of the mounting bracket 32, and the second limiting ring 33 has the same diameter as the first limiting ring 31, the other end of the second limiting ring 33 is opposite to the other end of the first limiting ring 31, and both ends of the second limiting ring 33 and the first limiting ring 31 are open, and the two openings correspond to the transposition groove 6 respectively, and one end of a pair of guide arms 34 is obliquely arranged on both ends of the mounting bracket 32. The intercepting arm 35 is detachably mounted between the other ends of the guide arms 34. The third motor 36 is fixedly mounted on the lower wall of the second limiting ring 33, and the driving end of the third motor 36 moves through the second limiting ring 33. One end of the toggle arm 37 is fixedly mounted on the driving end of the third motor 36. One end of a pair of conveyor belt assemblies 38 is respectively fixedly mounted on the other end of the first limiting ring 31 and the other end of the second limiting ring 33, and the conveyor belt assemblies 38 are relatively parallel to each other. One end of the carrier 39 is fixedly mounted on the lower wall of the first limiting ring 31 near one end and is located in front of the first limiting ring 31. The camera 40 is fixedly mounted On the other end of the carrier 39; the planetary carrier is carried and arranged by the conveyor belt assembly 38 and transported to the first limiting ring 31, so that the planetary carrier enters the transposition port 5 from between the first limiting ring 31 and the second limiting ring 33, and then moves the planetary carrier as the transposition disk 261 rotates. The camera 40 is used to visually determine the orientation of the planetary carrier and control the second motor 265 to drive the planetary carrier to rotate and adjust the boring processing position. The third motor 36 drives the toggle arm 37 to move the processed planetary carrier out of the mounting frame 32, and the guide arm 34 is used for unloading.

[0031] More specifically, the annular track formed by the first limiting ring 31 and the second limiting ring 33 ensures that the planetary carrier moves smoothly along the outer periphery of the transposition disk 261 to avoid positioning failure due to shaking. The camera 40 adopts industrial vision-based technology and cooperates with image processing algorithms to complete planetary carrier orientation recognition, angle adjustment feedback, and the swing path of the toggle arm 37 matches the planetary carrier gear column gap. Combined with the tilt angle design of the guide arm 34, automatic unloading is completed, which is more efficient than traditional manual unloading. The detachable design of the intercepting arm 35 allows the planetary carrier to be unloaded and then arranged and stacked on the guide arm 34.

[0032] As a further solution of the present invention, in order to enable automatic unloading, the toggle arm 37 is located between one pair of transposition openings 5, and the toggle arm 37 is swung by the third motor 36 to pass through one of the transposition openings 5 corresponding to the mounting bracket 32.

[0033] like Figure 5 As shown, as a further solution of the present invention, in order to be able to adjust the boring position, the camera 40 corresponds to one of the transposition ports 5 corresponding to the boring machine body 14.

[0034] like Figure 5 As shown, as a further solution of the present invention, the conveyor belt assembly 38 can sequentially convey the planet carrier to the transposition opening 5 of the transposition disk 261, and the planet carrier is moved in a circular shape on the first limiting ring 31 through the rotation of the transposition disk 261.

[0035] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0036] S1. After the base 8 is placed stably and the device is powered on, the planetary carrier with the protruding tooth column can be placed on the two conveyor belt assemblies 38. The tooth column is inserted between the two conveyor belt assemblies 38. The position of the planetary carrier with a larger diameter (the position for installing the planetary gear) is located above the conveyor belt assemblies 38 and locked in place. S2. The planet carrier is driven in the reverse direction by the conveyor belt assembly 38 to move toward the opening between the first limiting ring 31 and the second limiting ring 33 mounted by the mounting rod 30; the tooth column portion of the planet carrier is inserted into the transposition opening 5 of the transposition disk 261 in the transposition structure 2; S3, driving the first motor 23 on the boom 21, and the first motor 23 drives the driving gear 24 to rotate, and the engagement of the driving gear 24 with the driven gear 25 drives the driving shaft 22 to rotate, thereby driving the transposition disk 261 to rotate; the rotation of the transposition disk 261 drives the planetary carrier to move by means of the transposition opening 5, and the planetary carrier is supported by the transposition disk 261 and the first limiting ring 31, and the rotation of the transposition disk 261 can realize continuous loading; S4. The indexing plate 261 rotates to drive the planet carrier to a position opposite to the boring machine main body 14 in the main body structure 1. The boring machine main body 14 is driven to descend for boring feed by means of the lifting slide rail 12 on the positioning plate 11, and the boring machine main body 14 is driven to move left and right by the translation slide rail 13 to adjust the machining position of the boring tool. S5. Since the planet carrier may rotate during the rotation and movement of the indexing plate 261 and when the planet carrier enters the indexing opening 5 of the indexing plate 261, which may cause the position of the shaft hole where the planet gears of the planet carrier are installed to shift. As a result, after the planet carrier rotates to correspond to the boring machine main body 14, there may be a deviation in the boring machining position. Therefore, it can be determined by the imaging of the camera 40 on the carrier 39, and the second motor 265 in the indexing unit 26 in the indexing slot 6 is driven to drive the indexing wheel 266 to rotate. The indexing wheel 266 engages with the tooth column of the planet carrier to drive the planet carrier to rotate and adjust the machining position for alignment. S6. Boring machining can be carried out after the position is aligned. For example, if three planet gears are installed on the planet carrier, the indexing wheel 266 can be used to drive the planet carrier to rotate to achieve the machining of the shaft holes of the planet gears at three positions. S7. For planet carriers of different sizes, the diameters of the indexing plate 261, the first limiting ring 31, and the indexing opening 5, as well as the distance between the first limiting ring 31 and the indexing plate 261, can be set differently. At the same time, within a certain range, the adjusting nut 264 located in the adjusting slot 7 can be adjusted to move the adjusting seat 262 above the second motor 265 to adjust the position of the indexing wheel 266 in the indexing slot 6, so that the indexing wheel 266 can effectively contact the tooth column of the planet carrier. S8. After the boring machining of the planet carrier, as the indexing plate 261 rotates, the planet carrier is moved to the mounting frame 32. That is, the indexing opening 5 of the planet carrier part is opposite to the mounting frame 32. At this time, the third motor 36 on the second limiting ring 33 can be driven to drive the toggle arm 37 to rotate, so that the toggle arm 37 applies a force forward from the rear of the planet carrier to push the planet carrier out from the indexing plate 261, the first limiting ring 31, and the second limiting ring 33, and it slides out obliquely under the support of the two guide arms 34. An intercepting arm 35 can also be installed between the other ends of the two guide arms 34 to stack and arrange the machined planet carriers.
