Technical Field

[0001] This utility model relates to the field of gear shaft machining, and in particular to a bidirectional turning device for wear-resistant gear shafts. Background Technology

[0002] Wear-resistant gear shafts are widely used in various transmission systems. Generally, wear-resistant gear shafts consist of shaft segments of different diameters. During the turning process, only the different shaft segments need to be geared. These gear shafts are all formed using turning machine tools. However, in existing technologies, when gearing shaft segments of different diameters, it is necessary to constantly control the distance between the cutting tool and the shaft segment to be geared. Generally, the position of the cutting tool needs to be manually adjusted to create different gears. Furthermore, current methods all use a single-sided gearing approach, which severely impacts machining efficiency. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1:

[0026] Reference Figure 1-6A bidirectional turning device for wear-resistant gear shafts includes a support frame 1, a support plate 2 fixedly mounted on the top of the support frame 1, a rotary table 3 movably mounted on the support plate 2, and a clamping block 4 rotating under the action of a controller. Multiple clamping blocks 4 are slidably mounted on the upper surface of the rotary table 3, generally no fewer than three, to clamp the bottom of a vertically positioned wear-resistant gear shaft 13 and to clamp wear-resistant gear shafts 13 of different diameters. A support column 5 is also fixed to the lower surface of the support plate 2, and the bottom of the support column 5 is detachably connected to the middle of a connecting plate 6. A lifting cylinder 7 is symmetrically arranged on the support plate 2. During gear turning, the lifting cylinder 7 can move up and down continuously, thus driving a turning mechanism 8 to move up and down, located on both sides of the rotary table 3. The upper part of each lifting cylinder 7 is equipped with the turning mechanism 8. Each lifting cylinder 7 has its bottom passing through the support plate 2 and is fixedly connected to the movable column 9. The bottom of each movable column 9 is also rotatably connected to both ends of the connecting plate 6. A vertical side plate 10 is also fixed on the support plate 2. A pre-tightening cylinder 11 is also fixed on the vertical side plate 10. A conical seat 12 is fixed to the telescopic end of the pre-tightening cylinder 11. The wear-resistant gear shaft 13 to be processed is fitted between the conical seat 12 and the rotary table 3. Through the above scheme, it can first adapt to the tooth profile processing of wear-resistant gears 13 with different diameters. Moreover, a turning mechanism 8 is set on the upper part of each lifting cylinder 7, so that bidirectional tooth opening is formed on both sides of the rotary table 3, which improves the tooth opening efficiency of the wear-resistant gear shaft 13. The turning mechanism 8 can move up, down, left, and right. This process can continuously adapt to the processing of shaft segments with different diameters. The turning mechanism 8 can also rotate with the movable column 9, which facilitates the replacement of the cutting tool 84.

[0027] See Figure 6 The upper surface of the rotary table 3 is provided with multiple sliding grooves 14, and each sliding groove 14 is equipped with a clamping block 4. Each clamping block 4 can slide in the sliding groove 14, and each sliding groove 14 has a limiting groove 15 on both sides. Both sides of each clamping block 4 extend into the limiting groove 15. The limiting groove 15 mainly plays a stabilizing role, which can ensure that the clamping block 4 will not detach from the sliding groove 14 during the sliding process.

[0028] Each groove 14 is also provided with a first spring 16. One end of the first spring 16 is fixedly connected to the end of the groove 14, and the other end is fixedly connected to the clamping block 4. The first spring 16 mainly plays a pre-tightening role. During the processing, when the wear-resistant gear shaft 13 with a larger diameter is moved away from the center of the shaft, each clamping block 4 will move away from the center. This process continuously compresses the first spring 16, and under the action of the first spring 16, the wear-resistant gear shaft 13 can be clamped, so that it will not shake during rotation.

[0029] See Figure 2-3The top of the support column 5 is also provided with a threaded hole 17, which is connected to a screw. The screw is fixedly installed on the upper surface of the pre-tightening seat 18, and the pre-tightening seat 18 is located below the connecting plate 6. In this way, the connecting plate 6 can be detachably installed on the support column 5 through the pre-tightening seat 18.

[0030] The connecting plate 6 is also provided with sleeves 19 at both ends. Each sleeve 19 is rotatably connected to the corresponding movable column 9, and each movable column 9 is fixedly provided with a rotating arm 20. The rotating arm 20 is located below the support plate 2.

[0031] Two telescopic electric cylinders 21 are horizontally movably arranged below the support plate 2, and the telescopic end of each telescopic electric cylinder 21 is movably connected to one end of the corresponding rotating arm 20. The two telescopic electric cylinders 21 are horizontally movably installed on the support plate 2. When the telescopic end of the telescopic electric cylinder 21 extends or retracts, it can drive the rotating arm 20, which will drive the movable column 9 to rotate, thus adjusting the angle of the turning mechanism 8.

[0032] See Figure 3-5 The turning mechanisms 8 are symmetrically arranged on the corresponding lifting cylinders 7. Each turning mechanism 8 includes a top frame 80. Two guide columns 81 are fixedly arranged in the middle of the top frame 80. A movable seat 82 is movably arranged between the two guide columns 81. The movable seat 82 can move left and right along the guide columns 81 under the action of the drive cylinder 86. A turning shaft 83 is fixedly mounted on one side of the movable seat 82. A cutting tool 84 and a probe 85 are detachably arranged at the ends of the turning shaft 83. The cutting tool 84 mainly performs turning during the up and down lifting process, while the probe 85 mainly plays a detection role. Taking the left probe 85 as an example, when turning the first gear, the cutting tool 84 begins to move down with the lifting cylinder 7 to turn the gear. When the upper probe 85 contacts the upper end face, pressure is detected. At this time, the probe 85 will control the external controller, and the external controller will control the lifting cylinder 7 to move left and right. Moving upwards, the left probe 85 prevents the second gear from being machined. During this process, the right probe 85 mainly detects the distance from the second gear. That is, when the right probe 85 contacts the upper surface of the second gear, it detects a change in pressure. At this time, the right cutting tool 84 will not descend but will rise in the opposite direction. This ensures that the second gear will not be machined. This not only allows for machining from both sides simultaneously but also protects adjacent gears. During the machining process, the rotary table 3 will not rotate. It will only rotate once after machining a pair of teeth. When machining the second gear, both sides move away from each other and then move down to the position of the second gear, repeating the machining process of the first gear. This not only protects the first gear but also ensures the safety of the third or fourth gear below. The moving seat 82 is also fixedly connected to the telescopic end of the drive cylinder 86, which is fixedly mounted on the top frame 80.

[0033] The probe rod 85 is a pressure probe rod, and the sensing end of the probe rod 85 is connected to the signal of an external controller. During the tooth-opening process, the probe rod 85 mainly controls its up and down position based on pressure changes.

[0034] The extension and retraction end of the drive cylinder 86 is also fitted with a second spring 87. One end of the second spring 87 is fixedly connected to the inner side of the top frame 80, and the other end is fixedly connected to the moving seat 82. During the tooth opening process, the second spring 87 can buffer the impact of the cutting tool 84 and better protect the cutting tool 84.

[0035] One probe rod 85 is located above the corresponding cutting tool 84, and the other probe rod 85 is located below the corresponding cutting tool 84. This can better protect the upper and lower adjacent gears of the current gear. This method is suitable for the case where the diameters of adjacent shaft segments are different. When the diameters of adjacent gears are the same, the probe rod 85 can be omitted.

[0036] The principle of this utility model is as follows:

[0037] First, the wear-resistant gear shaft 13 to be processed is placed between the clamping blocks 4. The clamping blocks 4 clamp the bottom of the wear-resistant gear shaft 13. Then, the pre-tightening cylinder 11 drives the tapered seat 12 downward to fix the workpiece. At this time, the telescopic electric cylinder 21 starts to work, so that the movable column 9 drives the turning mechanism 8 to rotate a certain angle, so that the turning shaft 83 is close to the workpiece. Then, under the action of external control, the lifting cylinder 7 drives the turning mechanism 8 to move down to the designated position, and then turning is performed. During the turning process, the drive cylinder 86 can control the left and right movement of the cutting tool 84, that is, to control the turning depth. The length of the vertical tooth opening is controlled by the probe rod 85, and the probe rod 85 can ensure that the tooth opening of adjacent shaft sections will not affect each other. After each pair of teeth is opened, it is retracted and then rotated a certain angle to repeat the above process.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
