Description

Technical Field

[0001] The utility model relates to the technical field of automobile flexible shaft processing, in particular to an end chamfering device for automobile flexible shaft processing. Background Technique

[0002] In the fields of automobiles or other mechanical equipment, flexible shafts are often used to transmit torque. The flexible shaft is similar in shape to a screw rod and is provided with threaded steel wires on the outside, and the pitch is fixed. During the processing of the flexible shaft, chamfering is required at the end of the flexible shaft.

[0003] For example, the Chinese patent document with the publication number CN219520707U discloses a chamfering device for automobile half shaft processing, including a chamfering device and a support frame. The support frame is installed on the side of the debris box away from the chamfering device, and a limiting plate is installed above the support frame. A servo motor, a lead screw, a slider one and a placing plate are installed inside the support frame. Optical rods are installed at both ends of the slider one. A telescopic motor is installed inside the placing plate, and a slider two is installed inside the telescopic motor. A limiting ring is installed at the top of the slider two.

[0004] In the above technical solution, the telescopic motor pushes the slider two and the limiting ring to clamp the half shaft. The servo motor drives the lead screw to rotate, and then drives the slider one and the placing plate to slide along the lead screw and the optical rod. Then, through the placing plate, the limiting ring and the half shaft slide left and right, so that the half shaft reaches the specified position, and chamfering treatment of the half shaft can be conveniently and quickly achieved.

[0005] However, in the actual use process, due to the different sizes of the flexible shafts and the constant size of the limiting ring, different sizes of flexible shafts cannot be clamped, so chamfering processing of different sizes of flexible shafts cannot be carried out, and there are certain limitations in the scope of use. Summary of the Invention

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] Such as Figures 1 to 4As shown in the figure, the utility model discloses an end chamfering device for automobile flexible shaft processing, which includes a bottom plate 1. On the bottom plate 1, there are a first mounting seat 2 and a second mounting seat 3 arranged at intervals. The first mounting seat 2 is provided with a through hole 21 for the flexible shaft 100 to pass through. On the side of the first mounting seat 2 facing the second mounting seat 3, there is a clamping block 4 that can move radially. There are multiple clamping blocks 4 and they are evenly distributed in a circle. By moving the clamping block 4 radially, the clamping of flexible shafts 100 with different sizes can be achieved. A driving shaft is rotatably connected to the second mounting seat 3. A cutter head 5 is fixedly sleeved on the outer periphery of the driving shaft. A cutter head 6 that can move radially is provided on the cutter head 5. The driving shaft is connected to a first motor 7, and the first motor 7 is used to drive the driving shaft to rotate. When chamfering flexible shafts 100 with different sizes, by moving multiple clamping blocks 4 in the radial direction to match flexible shafts 100 with different sizes, the clamping of flexible shafts 100 with different sizes can be realized, and the chamfering processing of flexible shafts 100 with different sizes can be achieved, so that the applicable range can be expanded. And by arranging multiple clamping blocks 4, the clamping stability of the flexible shaft 100 can be improved. In addition, during the process of multiple clamping blocks 4 moving towards the flexible shaft 100, the flexible shaft 100 can be pushed towards the center, so as to realize the centering of the flexible shaft 100 and ensure the chamfering quality of the end of the flexible shaft 100.

[0022] In this embodiment, the principle of multiple clamping blocks 4 moving synchronously in the radial direction is as follows: A connecting plate 8 is fixed on the first mounting seat 2. An installation cavity 81 is provided in the connecting plate 8. A rotatable turntable 9 is provided in the installation cavity 81. A through first arc-shaped guiding hole 91 is provided on the turntable 9. A second arc-shaped guiding hole 82 is provided on the connecting plate 8. The second arc-shaped guiding hole 82 is located above the first arc-shaped guiding hole 91. There is a deviation angle between the second arc-shaped guiding hole 82 and the first arc-shaped guiding hole 91. A moving block 10 is provided between the turntable 9 and the connecting plate 8. A guiding rod 11 is provided on the moving block 10. Both ends of the guiding rod 11 extend towards the second arc-shaped guiding hole 82 and the first arc-shaped guiding hole 91 respectively and are coupled with the second arc-shaped guiding hole 82 and the first arc-shaped guiding hole 91 respectively. One end of the moving block 10 away from the guiding rod 11 extends out of the installation cavity 81 as a connecting end. The clamping block 4 is fixed to the connecting end. By rotating the turntable 9, since both ends of the guiding rod 11 are coupled with the second arc-shaped guiding hole 82 and the first arc-shaped guiding hole 91 respectively, and there is a deviation angle between the second arc-shaped guiding hole 82 and the first arc-shaped guiding hole 91, after the turntable 9 rotates, the guiding rod 11 can be driven to move along the path of the second arc-shaped guiding hole 82 through the first arc-shaped guiding hole 91. Thus, the clamping block 4 connected to the connecting end of the moving block 10 can move radially, so that it can quickly contact flexible shafts 100 with different sizes and realize the quick clamping or release of flexible shafts 100 with different sizes;

[0023] Among them, the specific structure for driving the turntable 9 to rotate is that a driving cylinder 12 is provided on the first mounting seat 2. A connection port 83 communicating with the mounting cavity 81 is provided on the peripheral wall of the connection disk 8. A connection flange 92 extending from the connection port 83 to the outside of the mounting cavity 81 is provided on the turntable 9. The output end of the driving cylinder 12 is rotatably connected to the connection flange 92. Therefore, by the telescopic movement of the output end of the driving cylinder 12, the turntable 9 can be driven to rotate clockwise and counterclockwise. In this way, through the rotation of the turntable 9, a plurality of clamping blocks 4 can be synchronously driven to move radially, realizing the rapid clamping or release of soft shafts 100 of different sizes.

[0024] In this embodiment, a guiding groove 84 formed by downward depression is further provided in the mounting cavity 81. The guiding groove 84 is located between adjacent first arc-shaped guiding holes 91. A guiding block 93 extending towards the guiding groove 84 is provided on the turntable 9. The guiding block 93 is coupled to the guiding groove 84 and can form a guiding fit therebetween. When the turntable 9 rotates, the guiding block 93 coupled in the guiding groove 84 can move along the path of the guiding groove 84, thereby forming a guiding fit therebetween, so as to be able to guide the rotation of the turntable 9 and ensure the stability of the turntable 9 during rotation.

[0025] In this embodiment, a roller 41 is further rotatably connected to the clamping block 4. Through the rotatably connected roller 41, after the roller 41 abuts against the soft shaft 100, it can clamp the soft shaft 100 while reducing the wear on the end of the soft shaft 100. And the roller 41 is rotatably connected in the axial direction, so as to ensure the stability of the clamping of the soft shaft 100 by the roller 41.

[0026] In this embodiment, the structure that enables the tool head 6 to move radially is as follows: on the side of the tool disc 5 facing the first mounting seat 2, there are symmetrically arranged mounting flanges 13. A lead screw 14 is rotatably connected between adjacent mounting flanges 13. Guide rods 15 are provided on both sides of the lead screw 14. A tool holder 16 that can form a threaded fit with the lead screw 14 is fixedly sleeved on the outer periphery of the lead screw 14. The tool holder 16 is provided with guide holes corresponding to the guide rods 15. A second motor 17 is provided at one end of the lead screw 14. The second motor 17 is used to drive the lead screw 14 to rotate. The tool head 6 is connected to the tool holder 16. Therefore, after the end of the flexible shaft 100 to be chamfered passes through the through hole 21 of the first mounting seat 2, the driving cylinder 12 drives the turntable 9 to rotate, driving the clamping block 4 to move radially. After the flexible shaft 100 is centered and clamped by the roller 41, the second motor 17 drives the lead screw 14 to rotate, so that the tool holder 16 sleeved on the outer periphery of the lead screw 14 and forming a threaded fit can move along the direction of the lead screw 14 under the guiding action of the guide hole and the guide rod 15 until the tool head 6 abuts against the end of the flexible shaft 100. Different sizes of flexible shafts 100 can be adapted to achieve chamfering processing of flexible shafts 100 of different sizes. Subsequently, the first motor 7 drives the drive shaft to rotate, enabling the tool head 6 to rotate around the flexible shaft 100, thus completing the chamfering processing of the end of the flexible shaft 100.

[0027] This specific embodiment is only an interpretation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
