Technical Field
[0001] This utility model relates to the field of rack processing technology, and in particular to a rack cutting device. Background Technology
[0002] In many fields of modern industrial production, racks are widely used as a key mechanical transmission component. Whether in the manufacture of precision instruments or the operation of large mechanical equipment, racks play an important role in converting rotary motion into linear motion or vice versa. The quality and precision of their specifications have a crucial impact on the overall performance of the equipment.
[0003] In the actual production process of racks, it is often necessary to cut long racks into small segments of a certain length according to different usage scenarios and equipment requirements. However, according to actual needs, racks need to be cut into segments of different lengths. Existing rack cutting devices can only cut racks into segments of a single length and cannot adjust the length of the rack cutting as needed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies that can only cut racks into small segments of a single length and cannot adjust the cutting length of the rack as needed, and to propose a rack cutting device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rack and pinion cutting device is designed, including a support frame. A slide rail is fixedly connected to the upper end of the support frame. A first movable plate is slidably connected to the slide rail. A notch is opened at the upper end of the support frame. A second movable plate is slidably inserted into the support frame. An adjusting component that drives the second movable plate to move horizontally is rotatably connected to the support frame. A scale is connected to the second movable plate. A mounting block is fixedly connected to one end of the second movable plate. A pressure sensor is connected to the mounting block. A support plate is fixedly connected to one side of the support frame. Two parallel roller limiting components are connected between the support plate and the support frame.
[0006] Preferably, the adjusting element is a threaded rod.
[0007] Preferably, the second movable plate and the mounting block are an integral structure.
[0008] Preferably, both sides of the support frame are fixedly connected to a debris collection mechanism. The debris collection mechanism includes a first connecting plate, one end of which is fixedly connected to the support frame, and the other end of which is fixedly connected to an open box. The upper end of the open box has a slot.
[0009] Preferably, the first movable plate is connected to a limiting mechanism for fixing the rack. The limiting mechanism includes a second connecting plate, one end of which is fixedly connected to the first movable plate, and the other end of which is fixedly connected to a fixed box. A movable block is slidably connected inside the fixed box. A spring is fixedly connected to the upper end of the movable block, one end of which is fixedly connected to the fixed box. A third connecting plate is fixedly connected to the bottom end of the movable block. One end of the third connecting plate extends outside the fixed box and is fixedly connected to a pressing block, which is located above the support plate.
[0010] Preferably, the extrusion block is a stainless steel block.
[0011] The rack cutting device proposed in this utility model has the following advantages: By rotating the adjusting component as needed, the second movable plate moves horizontally. A scale measures the distance the second movable plate moves, which in turn moves the mounting block. The mounting block then moves the pressure sensor, adjusting the distance between the pressure sensor and the notch, thereby adjusting the cutting length of the rack. Attached Figure Description

[0014] 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.
[0015] Example 1: Refer to Figure 1-3 A rack and pinion cutting device includes a support frame 1, a slide rail 2 fixedly connected to the upper end of the support frame 1, a first movable plate 3 slidably connected to the slide rail 2, an electric telescopic rod 4 connected to the upper end of the slide rail 2 to drive the first movable plate 3 to move vertically, a cutting machine 5 fixedly connected to the first movable plate 3, a notch 6 opened at the upper end of the support frame 1, the notch 6 cooperating with the cutting machine 5, a second movable plate 7 slidably inserted into the support frame 1, an adjusting member 8 rotatably connected to the support frame 1 to drive the second movable plate 7 to move horizontally, the adjusting member 8 being a threaded rod, a scale 10 connected to the second movable plate 7, a mounting block 9 fixedly connected to one end of the second movable plate 7, the second movable plate 7 and the mounting block 9 being an integral structure, a pressure sensor 11 connected to the mounting block 9, a support plate 12 fixedly connected to one side of the support frame 1, the upper end of the support plate 12 being flush with the upper end of the notch 6, and two parallel roller limiting members 13 connected between the support plate 12 and the support frame 1.
[0016] Work process: The rack conveyor pushes the rack, and one end of the rack passes between two roller limiters 13. After the two roller limiters 13 come into contact with the rack, they limit it. The rack conveyor continues to push the rack to move. After the rack moves a certain distance, it comes into contact with the pressure sensor 11 on the mounting block 9. After the pressure sensor 11 detects the pressure, the rack conveyor stops conveying the rack. When the cutting machine 5 is powered on and started, the electric telescopic rod 4 is also powered on and started. After the electric telescopic rod 4 is started, it drives the first movable plate 3 to move downwards by a set distance and then resets. After the first movable plate 3 moves, it drives the cutting machine 5 to move. During the downward movement, the cutting machine 5 contacts the rack and cuts it. After the first movable plate 3 moves upwards and resets, it drives the cutting machine 5 to move upwards and resets. One end of the cut rack contacts the support frame 1, and the other end of the rack contacts the pressure sensor 11. The middle area of the rack is in a suspended state. The cut rack falls downwards under its own weight. Rotate the adjusting component 8 as needed. After the adjusting component 8 rotates, the second movable plate 7 moves in the horizontal direction. The scale 10 measures the moving distance of the second movable plate 7. The second movable plate 7 drives the mounting block 9 to move. The mounting block 9 drives the pressure sensor 11 to move. Adjust the distance between the pressure sensor 11 and the notch 6 to adjust the cutting length of the rack.
[0017] Example 2: During the cutting process of the toothed rack of the cutting machine 5, the debris generated during the cutting process splashes and is inconvenient to collect. (Refer to...) Figure 3 As another preferred embodiment of this utility model, the difference from embodiment 1 is that both sides of the support frame 1 are fixedly connected to a debris collection mechanism 14. The debris collection mechanism 14 includes a first connecting plate 141. One end of the first connecting plate 141 is fixedly connected to the support frame 1, and the other end of the first connecting plate 141 is fixedly connected to an open box 142. The upper end of the open box 142 is provided with a slot 143. The first connecting plate 141 fixes the open box 142. The open box 142 is located outside the recess 6 and collects the debris generated during the cutting process to reduce debris splashing.
[0018] Example 3: During the cutting process of the rack, the rack is prone to movement. (Refer to...) Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a limiting mechanism 15 for fixing the rack is connected to the first movable plate 3. The limiting mechanism 15 includes a second connecting plate 151. One end of the second connecting plate 151 is fixedly connected to the first movable plate 3, and the other end of the second connecting plate 151 is fixedly connected to a fixed box 152. A movable block 153 is slidably connected inside the fixed box 152. A spring 154 is fixedly connected to the upper end of the movable block 153. One end of the spring 154 is fixedly connected to the inside of the fixed box 152. A third connecting plate 155 is fixedly connected to the bottom end of the movable block 153. One end of the third connecting plate 155 extends to the outside of the fixed box 152 and is fixedly connected to a pressing block 156. The pressing block 156 is located above the support plate 12 and is a stainless steel block. When the first movable plate 3 moves downward, it drives the second connecting plate 151 to move. The second connecting plate 151 drives the fixed box 152 to move. The fixed box 152 drives the spring 154 to move. The spring 154 drives the movable block 153 to move. The movable block 153 drives the third connecting plate 155 to move. The third connecting plate 155 drives the pressing block 156 to move. After the pressing block 156 moves downward a certain distance, it contacts the rack. After the first movable plate 3 continues to move downward, it presses the spring 154 through the fixed box 152. The spring 154 generates elastic force after being pressed. The elastic force generated by the spring 154 pushes the third connecting plate 155 downward, thereby limiting the pressing block 156 to the rack and preventing the rack from moving during the cutting process, thus improving the rack cutting effect.
[0019] 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.
