Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0059] It should be noted that the directional words such as "up, down, front, back, left, right, inside, outside" below are all defined based on the drawings in the specification.

[0060] The core of the utility model is to provide a transmission shaft tube chamfering device, which can realize the automatic processing process of the tube chamfering to improve the processing efficiency of the transmission shaft tube chamfering and can also adapt to the processing of the chamfering of transmission shaft tubes of different sizes.

[0061] Please refer to Figure 1 , Figure 2 and Figure 3 A transmission shaft tube chamfering device includes a workbench 1, a control device, a driving device, a moving plate 3, a fixed plate 4, a tool assembly 5, a feeding assembly 6, a clamping assembly 7 and an adjusting assembly 8.

[0062] Specifically, the driving device, the tool assembly 5, the feeding assembly 6, the clamping assembly 7, and the adjusting assembly 8 are all connected to the control device, and the operating status of the driving device, the tool assembly 5, the feeding assembly 6, the clamping assembly 7 and the adjusting assembly 8 are controlled by the control device. The workbench 1 is provided with a guide rail 2 extending along its length direction, and is also provided with a driving device for driving the movable plate 3 to slide along the guide rail 2 and a fixed plate 4 arranged at one end of the guide rail 2. The driving device is controlled by the control device to drive the movable plate 3 to slide along the guide rail 2, thereby driving the various components on the movable plate 3 to move synchronously.

[0063] The tool assembly 5, the feeding assembly 6, the clamping assembly 7 and the adjusting assembly 8 are each provided with two groups, one group is arranged on the movable plate 3 and moves synchronously with the movable plate 3, and the other group is arranged on the fixed plate 4. The two groups of tool assemblies 5 are movably arranged at the outer ends of the corresponding movable plate 3 and the fixed plate 4 along the length direction of the workbench 1 to adapt to the transmission shaft shaft tubes of different lengths and realize the rapid positioning of the shaft tubes of different lengths. The two groups of feeding assemblies 6 are arranged at the inner ends of the corresponding movable plate 3 and the fixed plate 4. By setting the feeding assembly 6, the automatic feeding process of the shaft tube can be realized under the control of the control device. The two groups of adjusting assemblies 8 are liftable and arranged at the corresponding movable plate 3 and the fixed plate 4, and are located on the outer side of the clamping assembly 7. The adjusting assembly 8 is controlled by the control device to adjust the shaft tube on the feeding assembly 6 to the correct position. The two groups of clamping assemblies 7 are liftable and arranged at the corresponding movable plate 3 and the fixed plate 4, and are located on the outer side of the feeding assembly 6. The clamping assembly 7 is controlled by the control device to position the shaft tube on the feeding assembly 6 to prevent the shaft tube from moving during the chamfering process.

[0064] When it is necessary to chamfer the shaft tube, the control device first controls the moving plate 3 to drive a group of tool assemblies 5, feeding assemblies 6, clamping assemblies 7 and adjustment assemblies 8 to move to a position corresponding to the length of the shaft tube, and then controls the feeding assembly 6 to perform an automatic loading process. When the shaft tube is loaded, the adjustment assembly 8 is controlled to operate, and after the shaft tube is adjusted to the correct position, the clamping assembly 7 is controlled to operate, so that the clamping assembly 7 positions the shaft tube after the adjusted position, and then the adjustment assembly 8 is controlled to operate to leave a position for the tool assembly 5, and the tool assembly 5 is further controlled to operate to perform internal and external chamfering on the shaft tube. After the processing is completed, it runs to the initial position to prepare for the next chamfering of the shaft tube. The above-mentioned device can realize the full automation of the chamfering process of the transmission shaft shaft tube and improve the efficiency of the chamfering of the transmission shaft shaft tube.

[0065] Among them, both ends of the transmission shaft tube need to be chamfered, so the same equipment is used on both sides of the transmission shaft tube, and each component on the movable plate 3 can be moved to adapt to the different size requirements of the transmission shaft tube.

[0066] The transmission shaft tube chamfering device arranged in the above manner can be applied to the chamfering of transmission shaft tubes of different lengths, can realize the fully automated process of the transmission shaft tube chamfering, and improve the efficiency of the transmission shaft tube chamfering.

[0067] In the above embodiment, the driving device includes a first servo motor and a screw rod. The first servo motor is arranged at one end of the workbench 1 and is connected to the control device. The screw rod is connected to the output end of the first servo motor and is arranged parallel to the guide rail 2. A moving block connected to the moving plate 3 is provided on the screw rod.

[0068] It should be noted that a screw is provided below the movable plate 3 to connect the first servo motor, so that the components on the movable plate 3 can be moved under the action of the screw according to the length of the transmission shaft tube, so as to realize rapid positioning of the transmission shaft tube, thereby adapting to transmission shaft tubes of different lengths.

[0069] Among them, in this embodiment, the driving device is configured in this way, but in practical applications, there is no limitation to this, as long as the above-mentioned technical effects can be achieved.

[0070] In the above situation, the tool assembly 5 includes a mounting seat 51, a first motor 52 and a cutter head 53. The first motor 52 is arranged on the mounting seat 51. The output end of the first motor 52 is connected to the cutter head 53. The output end of the first motor 52 is extended and retracted in a direction parallel to the guide rail 2. The first motor 52 is connected to the control device.

[0071] It can be understood that the inner and outer cutter heads 53 on the tool assembly 5 can simultaneously perform inner and outer chamfering of the plane. When the drive shaft tube is adjusted to the correct position and fixed, the first motor 52 is controlled by the control device to drive the cutter head 53 to rotate, thereby performing inner and outer chamfering on the drive shaft tube.

[0072] Furthermore, both the movable plate 3 and the fixed plate 4 are provided with a linear rail 9 parallel to the guide rail 2 , and the mounting seat 51 is driven by a second motor 54 to move along the linear rail 9 , and the second motor 54 is connected to the control device.

[0073] It should be noted that when the transmission shaft tube is adjusted to the correct position and fixed, the control device controls the second motor 54 to run, driving the mounting seat 51 to move forward along the linear rail 9, and at the same time controls the first motor 52 to run, driving the cutter head 53 to rotate, and chamfering the transmission shaft tube inside and outside. When the chamfering of the transmission shaft tube is completed, the mounting seat 51 is controlled to withdraw backward through the second motor 54, and the clamping assembly 7 is controlled to loosen, so that the feeding assembly 6 starts to run, and the loading, adjustment, fixing and processing actions are repeated.

[0074] In the above embodiment, the feeding assembly 6 includes a support plate 61, a second servo motor 62, an angle speed regulator 63, a swing arm 64 and a placement plate 65. The support plate 61 is vertically arranged at the inner ends of the movable plate 3 and the fixed plate 4. The second servo motor 62 is installed on the movable plate 3 and the fixed plate 4. The output end of the second servo motor 62 is connected to the angle speed regulator 63. The second servo motor 62 and the angle speed regulator 63 are both connected to the control device. One end of the swing arm 64 is rotatably connected to the output end of the angle speed regulator 63, and the other end of the swing arm 64 is connected to the placement plate 65 arranged parallel to the support plate 61. The upper end surfaces of the placement plate 65 and the support plate 61 are provided with multiple corresponding operating grooves.

[0075] It can be understood that the transmission shaft tube enters the operating groove through the rotation of the feeding assembly 6, and the control device controls the operation of the second servo motor 62 and controls the angle speed regulator 63. The angle speed regulator 63 drives the swing arm 64 to rotate 360 ​​degrees. The swing arm 64 is connected to the placement plate 65, so the placement plate 65 also moves 360 degrees with the swing arm 64, thereby transporting the transmission shaft tube from one operating groove to the next operating groove, and further controlling the adjustment assembly 8 to adjust the transmission shaft tube so that the transmission shaft tube is adjusted to the correct position.

[0076] On the basis of the above-mentioned embodiment, the clamping assembly 7 includes a mounting bracket 71, a pneumatic booster cylinder 72 and a chuck 73. The mounting bracket 71 is vertically arranged on the movable plate 3 and the fixed plate 4. The pneumatic booster cylinder 72 is arranged on the mounting bracket 71 and is connected to the control device. The pneumatic booster cylinder 72 is located above the support plate 61. The output end of the pneumatic booster cylinder 72 can be moved up and down. The chuck 73 is connected to the output end of the pneumatic booster cylinder 72, and an arc groove is provided at the end of the chuck 73.

[0077] It should be noted that when the transmission shaft tube adjusted to the correct position needs to be chamfered, the control device controls the air pressure booster cylinder 72 to operate, so that the output end of the air pressure booster cylinder 72 moves downward, so as to drive the chuck 73 to move downward, until the arc groove of the chuck 73 abuts against the transmission shaft tube, so that the transmission shaft tube is fixed, and the movement of the transmission shaft tube during the chamfering process can be avoided. The tool assembly 5 is further controlled to perform chamfering on both ends of the transmission shaft tube at the same time. After the chamfering of the transmission shaft tube is completed, the air pressure booster cylinder 72 is controlled to operate, so that the output end of the air pressure booster cylinder 72 moves upward, so as to drive the chuck 73 to move upward, until the chuck 73 is separated from the transmission shaft tube and there is no interference between the two.

[0078] In the above embodiment, a guide rod is provided on the clamp 73, and a through hole matching with the guide rod is provided on the mounting bracket 71.

[0079] It is understandable that two guide rods are provided on both sides of the chuck 73. When the control device controls the operation of the air pressure booster cylinder 72, the output end of the air pressure booster cylinder 72 will not deflect when moving up and down, so as to ensure that the chuck 73 can be smoothly abutted and clamped with the transmission shaft tube.

[0080] In practical applications, other guiding methods may also be used without limitation, as long as the above-mentioned technical effects can be achieved.

[0081] Please refer to Figure 2 and Figure 3 The adjustment assembly 8 arranged on the movable plate 3 includes a first cylinder 81 and an adjustment block 82. The first cylinder 81 is arranged on the mounting bracket 71 and is located on the outside of the air pressure boosting cylinder 72 and above the support plate 61. The first cylinder 81 is connected to the control device. The output end of the first cylinder 81 can be moved up and down. The adjustment block 82 is arranged at the output end of the first cylinder 81, and the inner bottom of the adjustment block 82 has a taper.

[0082] It should be noted that after the feeding assembly 6 completes the feeding of the drive shaft tube, the control device controls the first cylinder 81 to operate, so that the output end of the first cylinder 81 moves downward to drive the adjustment block 82 to move downward until the adjustment block 82 abuts against the end of the drive shaft tube, and continues to control the output end of the first cylinder 81 to move downward to adjust the position of the drive shaft tube. When the adjustment assembly 8 completes the position adjustment of the drive shaft tube, the air pressure booster cylinder 72 is controlled to operate, so that the output end of the air pressure booster cylinder 72 moves downward to drive the chuck 73 to move downward until the arc groove of the chuck 73 abuts against the drive shaft tube so that the drive shaft tube is fixed. Then, the first cylinder 81 is controlled to operate, so that the output end of the first cylinder 81 moves upward to drive the adjustment block 82 to move upward, thereby providing space for the operation of the tool assembly 5.

[0083] The adjustment assembly 8 on the movable plate 3 is used to adjust the front and rear position of the transmission shaft tube. When the transmission shaft tube enters the operating slot, the first cylinder 81 presses down to drive the adjustment block 82, and the slope of the adjustment block 82 allows the transmission shaft tube to move to the right.

[0084] Please refer to Figure 2 , Figure 3 and Figure 5 The adjustment assembly 8 arranged on the fixed plate 4 includes a second cylinder 83 and a spring piece 84. The second cylinder 83 is arranged on the mounting bracket 71 and is located on the outside of the air pressure boosting cylinder 72 and above the support plate 61. The second cylinder 83 is connected to the control device. The output end of the second cylinder 83 can be moved up and down. The spring piece 84 is arranged at the output end of the second cylinder 83, and the inner side of the spring piece 84 has a taper.

[0085] It can be understood that when the feeding assembly 6 completes the feeding of the drive shaft tube, the control device controls the operation of the second cylinder 83 to move the output end of the second cylinder 83 downward to drive the spring piece 84 to move downward to a position corresponding to the spring piece 84 and the end of the drive shaft tube, and the spring piece 84 abuts against the end of the drive shaft tube. When the output end of the second cylinder 83 continues to move downward, the conical surface of the spring piece 84 will squeeze the drive shaft tube to the left, so that the end of the drive shaft tube abutting against the adjustment block 82 moves from the slope of the adjustment block 82 to the plane of the adjustment block 82.

[0086] Among them, the adjustment block 82 is a right-angled trapezoidal structure, and the slope is located at the lower end of the side close to the transmission shaft shaft tube. The spring piece 84 is a right-angled triangle structure, and the inclined surface is located on the side close to the transmission shaft shaft tube. In this embodiment, the adjustment block 82 and the spring piece 84 are arranged in this way, but in actual application, there is no limitation to this, as long as the above-mentioned technical effect can be achieved.

[0087] Furthermore, the spring piece 84 has a certain elasticity to meet the pressure exerted by the adjustment block 82 through the transmission shaft tube in the next process, thereby avoiding the spring piece 84 and the adjustment block 82 from breaking during the downward movement.

[0088] When using the adjustment component 8 to adjust the position of the drive shaft tube, the control device first controls the output end of the first cylinder 81 to move downward to drive the adjustment block 82 to move downward, and the end of the drive shaft tube contacts the slope of the adjustment block 82, and the drive shaft tube moves to the right under the squeezing of the slope of the adjustment block 82, and then controls the output end of the second cylinder 83 to move downward to drive the spring plate 84 to move downward, so that the inclined surface of the spring plate 84 abuts against the end of the drive shaft tube, and the spring plate 84 can push the drive shaft tube to the left to ensure that the front and rear positions of the drive shaft tube are in a correct operating position. Once the drive shaft tube contacts the flat surface of the adjustment block 82, it will no longer move to complete the adjustment of the position of the drive shaft tube.

[0089] When the adjustment component 8 completes the position adjustment of the transmission shaft tube, the air pressure booster cylinder 72 is controlled to operate so that the output end of the air pressure booster cylinder 72 moves downward to drive the chuck 73 to move downward until the arc groove of the chuck 73 abuts against the transmission shaft tube, and the air pressure of the air pressure booster cylinder 72 is used to fix the transmission shaft tube. Then, the first cylinder 81 and the second cylinder 83 are controlled to operate so that the output ends of the first cylinder 81 and the second cylinder 83 move upward to drive the adjustment block 82 and the spring 84 to move upward, thereby providing space for the operation of the tool assembly 5.

[0090] In the above embodiment, the control device is connected to the operation screen 10, and the operation screen 10 is provided with a plurality of operation buttons.

[0091] It should be noted that the control device is started through the operation panel 10 to control various components.

[0092] In summary, the drive shaft tube chamfering device provided by the utility model starts the feeding assembly 6 through the operating screen 10, so that the drive shaft tube enters the operating groove through the rotation of the feeding assembly 6, controls the adjustment assembly 8 to adjust the front and rear position of the drive shaft tube, controls the clamping assembly 7 to move downward to clamp the drive shaft tube, controls the adjustment assembly 8 to reset to the initial position, controls the inner and outer cutter heads 53 on the tool assembly 5 to simultaneously perform inner and outer chamfering of the plane, and after completion, controls the clamping assembly 7 to rise, controls the feeding assembly 6 to operate again, and transfers the completed drive shaft tube to the next operating groove until the drive shaft tube falls into the unloading frame.

[0093] The transmission shaft tube chamfering device of the utility model can automatically load, adjust, press, chamfer and unload materials. The fully automated process from loading to chamfering to final unloading does not require manual operation, only watching, and one person can watch multiple machines.
