Description

Technical Field

[0001] The utility model relates to the technical field of flexible shaft processing, in particular to a flexible shaft end linting device used for flexible shaft processing. Background Art

[0002] In the field of automobiles or other mechanical equipment, flexible shafts are often used to transmit torque. In order to prevent the gap between the square head of the flexible shaft and the square hole of the coupling in the engine or output device from being too large, it is necessary to flock the surface of the flexible shaft. There are two main existing flocking methods. One is to wrap the wool thread around the outer periphery of the flexible shaft and then heat the wool thread to make the wool thread adhere to the outer periphery of the flexible shaft. The other is to coat the mixture of wool and flocking glue on the outer periphery of the flexible shaft, and then heat and cure the mixture of wool and flocking glue to form a flocking layer on the outer periphery of the flexible shaft. Although the second method is more convenient and quick in flocking the flexible shaft, the formed flocking layer will cover the end of the flexible shaft, so the end of the flexible shaft needs to be de-flocked.

[0003] For example, a Chinese patent document with publication number CN216858242U discloses a de-linting device for the end of a flexible shaft, comprising a fixing plate and a shell installed on the fixing plate, and an opening is provided on one side of the shell, a fixing seat is installed inside the shell, a clamping mechanism, a positioning mechanism, a de-linting mechanism, a driving mechanism, and a de-linting length control mechanism are respectively provided on the fixing seat, a de-linting mechanism is respectively provided inside the fixing seat for de-linting the flexible shaft, the de-linting mechanism comprises a three-jaw chuck and a cutter, the three-jaw chuck is sleeved on the driving mechanism, and the cutter is installed on the three-jaw chuck through a cutter mounting block.

[0004] In the above technical solution, the delinting length control mechanism drives the flexible shaft to push in or out the cutter to achieve delinting of the end of the flexible shaft. However, the delinting length control mechanism drives the flexible shaft to move a constant distance, so that the delinting length of the end of the flexible shaft is also constant. However, in actual use, when connected to different devices, the requirements for the length of the end of the flexible shaft are not consistent.

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

[0019] like Figures 1 to 4As shown, the utility model discloses a soft shaft end linting device for soft shaft processing, comprising a machine table 1, a fixed table 2 and a movable table 3 are arranged on the machine table 1, a wire hole 21 for the soft shaft to pass through is arranged on the fixed table 2, a horizontally symmetrical top connecting seat 4 and a bottom connecting seat 5 are arranged on the movable table 3, a top V-shaped cutter head 41 and a bottom V-shaped cutter head 51 are connected to the top connecting seat 4 and the bottom connecting seat 5 respectively, an indentation area is formed between the top V-shaped cutter head 41 and the bottom V-shaped cutter head 51, a pressing mechanism is arranged on the movable table 3, and the pressing mechanism is used to drive the top connecting seat 4 and the bottom connecting seat 5 to move. The connecting seat 5 moves toward each other so that the top V-shaped blade 41 and the bottom V-shaped blade 51 make indentations on the surface of the flexible shaft. A moving mechanism is provided on the fixed table 2, and the moving mechanism is used to drive the relative movement between the moving table 3 and the fixed table 2 so that the flocking layer at the end of the flexible shaft can be peeled off. A fixed-length mechanism is provided between the top connecting seat 4 and the bottom connecting seat 5. The fixed-length mechanism is used to position the length of the flexible shaft passing through the wire hole 21 to adjust the distance between the end of the flexible shaft and the indentation area, thereby realizing the adjustment of the de-pilling length of the end of the flexible shaft to better meet the actual production and processing requirements.

[0020] In this embodiment, the specific structure of the fixed length mechanism includes a connecting flange 61 symmetrically fixed to the moving platform 3, an adjusting screw 62 is provided between the connecting flanges 61 on both sides, the adjusting screw 62 is driven by a corresponding motor, a moving seat 63 is sleeved on the outer periphery of the adjusting screw 62, the moving seat 63 and the adjusting screw 62 form a threaded fit, guide rods 64 are provided on both sides of the adjusting screw 62, the guide rods 64 pass through the moving seat 63, a positioning seat 65 is provided on the moving seat 63, a positioning hole 651 is provided in the positioning seat 65, and the positioning hole 651 is opposite to the wire hole 21, and by rotating the adjusting screw 62, the moving seat sleeved on the outer periphery of the adjusting screw 62 and capable of forming a threaded fit 63, can move along the direction of the adjusting screw 62 under the guidance of the guide rod 64, so as to drive the positioning seat 65 to move. Therefore, by driving the positioning seat 65 to move, the distance of the flexible shaft inserted into the positioning hole 651 can be adjusted, so that the distance between the end of the flexible shaft and the indentation area can be adjusted, so as to achieve the adjustment of the depilatory length of the end of the flexible shaft. It can be seen that when the positioning seat 65 moves to fit with the bottom V-shaped cutter head 51, it is the minimum depilatory length, and the maximum depilatory length depends on the moving distance of the moving platform 3. By driving the positioning seat 65 to move by adjusting the screw 62, the movement of the positioning seat 65 is more precise.

[0021] In this embodiment, the specific structure of the pressure mechanism includes a mounting seat 71, which is movably connected to the moving platform 3, and a pressure cylinder 72 is fixed on the mounting seat 71. The moving platform 3 is located on a side facing away from the top connecting seat 4 and the bottom connecting seat 5 and is movably connected with a top transmission rod 73 and a bottom transmission rod 74. One end of the top transmission rod 73 is movably connected to the output end of the pressure cylinder 72, and the other end is movably connected to the bottom transmission rod 74. The top transmission rod 73 and the bottom transmission rod 74 are respectively provided with a top flange 731 and a bottom flange 741, and the top flange 731 and the bottom flange 741 are respectively movably connected to the top connecting seat 4 and the bottom connecting seat 5. The top connecting seat 4 and the bottom connecting seat 5 are respectively provided with a top slide and a bottom slide. The machine 1 is provided with a top guide rail 75 and a bottom guide rail 76 corresponding to the top slide and the bottom slide, and the top slide and the bottom slide are respectively coupled to the top guide rail 75 and the bottom guide rail 76, and form a sliding fit with each other.

[0022] By controlling the extension and retraction of the output end of the pressure cylinder 72, the top transmission rod 73 is driven to rotate. Since the top transmission rod 73 is movably connected to the bottom transmission rod 74, the bottom transmission rod 74 can be driven to rotate at the same time. Therefore, as the top transmission rod 73 and the bottom transmission rod 74 rotate, the top guide rail 75 and the bottom guide rail 76 respectively slide with the top slide groove and the bottom slide groove to guide the movement path of the top connecting seat 4 and the bottom connecting seat 5, so that the top connecting seat 4 and the bottom connecting seat 5 can move between them. Moving toward or away from each other, when the top connecting seat 4 and the bottom connecting seat 5 move toward each other, the top V-shaped blade head 41 and the bottom V-shaped blade head 51 can be pressed on the surface of the flexible shaft respectively to form an indentation on the surface of the flexible shaft. At this time, the moving platform 3 is driven by the moving mechanism to move, so that the flocking layer at the end of the flexible shaft can be peeled off. The peeling principle is the same as the stripping principle of the wire stripping pliers. In addition, it should be noted that when the flocking layer at one end of the flexible shaft is peeled off by the moving mechanism driving the moving platform 3, the other end of the flexible shaft should be clamped by manual holding or mechanical clamping.

[0023] In this embodiment, the specific structure of the moving mechanism includes a pushing cylinder 81, which is fixed to the fixed table 2, and the output end of the pushing cylinder 81 is connected to the moving table 3. A slide rail 82 is provided on the fixed table 2, and a slide 83 corresponding to the slide rail 82 is provided on the moving table 3. The slide 83 is coupled to the slide rail 82 and can form a sliding fit between the two. After the top V-shaped cutter head 41 and the bottom V-shaped cutter head 51 press an indentation on the surface of the soft shaft, the output end of the pushing cylinder 81 is extended to drive the moving table 3 to move, so that the flocking layer at the end of the soft shaft can be peeled off, and during the movement of the moving table 3, the slide 83 and the slide rail 82 can form a sliding fit, which guides the movement of the moving table 3 and makes the movement of the moving table 3 more stable.

[0024] In this embodiment, a spacing is provided between the top guide rail 75 and the bottom guide rail 76, and the top V-shaped blade head 41 and the bottom V-shaped blade head 51 extend toward each other respectively. The reserved spacing can provide an installation space for the installation of the fixed-length mechanism, and by extending the top V-shaped blade head 41 and the bottom V-shaped blade head 51 toward each other respectively, the installed fixed-length mechanism can be prevented from interfering with the movement of the top V-shaped blade head 41 and the bottom V-shaped blade head 51 toward the flexible shaft, thereby affecting the formation of indentations on the surface of the flexible shaft.

[0025] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
