Abstract
Description
Technical Field
[0001] This application relates to the field of material conveying, and in particular to a high-speed rectangular motion mechanism. Background Technology
[0002] Material handling often involves transporting individual materials from one process to another. Currently, this is usually done manually, transferring materials one by one, which is labor-intensive.
[0003] Existing rectangular motion mechanisms are usually implemented through complex linkage mechanisms or servo control systems. Although these mechanisms can achieve rectangular trajectory motion, they are complex in structure and have high manufacturing costs.
[0004] Therefore, it is necessary to design a high-speed rectangular motion mechanism with a simple structure that facilitates the conveying of materials. Utility Model Content
[0005] To facilitate the conveying of individual materials, this application provides a high-speed rectangular motion mechanism.
[0006] This application provides a high-speed rectangular motion mechanism, which adopts the following technical solution:
[0007] A high-speed rectangular motion mechanism includes a worktable with a turntable rotatably connected to it. The turntable has a groove on its surface, and a cam is fixedly positioned at the center of the groove. The inner wall of the groove mates with the outer wall of the cam. A moving block is positioned between the groove and the cam, and the moving block is slidably connected to the turntable. A sliding plate is mounted on the moving block. A moving assembly on the worktable enables the sliding plate to move linearly. A connecting shaft is coaxially fixedly connected to the center of the top of the cam. A first connecting rod is fixedly connected to the end of the connecting shaft. A second connecting rod is rotatably connected to the end of the first connecting rod away from the connecting shaft. A third connecting rod is rotatably connected to the end of the second connecting rod away from the first connecting rod. A connecting member is fixedly connected to the end of the third connecting rod away from the second connecting rod. The connecting member is located above the sliding plate. A limiting assembly is provided on the sliding plate to restrict the linear movement of the connecting member. An execution plate is positioned at the end of the connecting member away from the third connecting rod.
[0008] By adopting the above technical solution, the turntable rotates, and the cam rotates along with the turntable. Under the action of the outer wall of the cam and the inner wall of the wheel groove, the sliding plate is limited by the moving component, causing the moving block to reciprocate linearly along the width direction of the worktable, thereby causing the sliding plate to reciprocate linearly. During the rotation of the cam, the connecting shaft, the first connecting rod, the second connecting rod and the third connecting rod drive the connecting member to move. The connecting member is limited by the limiting component on the sliding plate, causing the connecting member to reciprocate linearly along the length direction of the worktable. Under the action of the sliding plate, the connecting member causes the execution plate to make rectangular movements. The structure is simple and convenient for conveying materials.
[0009] Optionally, the moving component includes two slide rails arranged along the width direction of the worktable. The bottom of the sliding plate is provided with two sliding blocks that cooperate with the slide rails. The sliding blocks have sliding grooves that cooperate with the slide rails. The slide rails are located in the sliding grooves and are movably connected to the sliding blocks.
[0010] By adopting the above technical solution, during the rotation of the cam and the movement of the connecting block under force, since the connecting block is fixedly connected to the sliding plate, the sliding plate moves under force, and the sliding block moves along the slide rail, thereby limiting the movement of the sliding plate and making the sliding plate only move along the width direction of the worktable.
[0011] Optionally, the limiting component includes a limiting block, which is arranged along the length of the worktable. The limiting block has a limiting groove that mates with a connecting member. The connecting member is located in the limiting groove and is movably connected to the limiting block.
[0012] By adopting the above technical solution, during the rotation of the cam, the connecting member is moved by the connecting shaft, the first connecting rod, the second connecting rod and the third connecting rod. The force transmitted by the third connecting rod of the connecting member moves the connecting member. Under the action of the upper limit groove of the limiting block, the connecting member moves along the limiting groove.
[0013] Optionally, the worktable is equipped with a drive motor for driving the turntable to rotate, and the output shaft of the drive motor is coaxially and fixedly connected to the turntable.
[0014] By adopting the above technical solution, the drive motor works to drive the turntable and the cam on the turntable to rotate, and the working speed of the entire rectangular motion mechanism is controlled by the rotation speed of the output shaft of the drive motor.
[0015] In summary, this application includes at least one of the following beneficial technical effects:
[0016] When the turntable rotates, the cam rotates along with it. Under the action of the outer wall of the cam and the inner wall of the wheel groove, the sliding plate is limited by the moving component, causing the moving block to reciprocate linearly along the width of the worktable. This causes the sliding plate to reciprocate linearly. During the rotation of the cam, the connecting shaft, the first connecting rod, the second connecting rod, and the third connecting rod drive the connecting member to move. The connecting member is limited by the component on the sliding plate, causing it to reciprocate linearly along the length of the worktable. Under the action of the sliding plate, the connecting member causes the actuator plate to make a rectangular motion. The structure is simple and convenient for conveying materials.

[0021] The present application will be further described in detail below with reference to all the accompanying drawings.
[0022] This application discloses a high-speed rectangular motion mechanism.
[0023] Reference Figure 1 and Figure 2 A high-speed rectangular motion mechanism includes a worktable 1, a turntable 2 rotatably connected to the worktable 1, a wheel groove 21 formed on the surface of the turntable 2, a cam 3 fixedly positioned at the center of the wheel groove 21, the inner wall of the wheel groove 21 engaging with the outer wall of the cam 3, a moving block 4 positioned between the wheel groove 21 and the cam 3, the moving block 4 slidably connected to the turntable 2, a sliding plate 5 mounted on the moving block 4, a moving assembly on the worktable 1 for linear motion of the sliding plate 5, and a connecting rod coaxially fixedly connected to the center of the top of the cam 3. A connecting shaft 31 is fixedly connected to a first connecting rod 61 at one end. A second connecting rod 62 is rotatably connected to the end of the first connecting rod 61 away from the connecting shaft 31. A third connecting rod 63 is rotatably connected to the end of the second connecting rod 62 away from the first connecting rod 61. A connecting piece 6 is fixedly connected to the end of the third connecting rod 63 away from the second connecting rod 62. The connecting piece 6 is located above the sliding plate 5. A limiting component is provided on the sliding plate 5 to limit the linear movement of the connecting piece 6. An execution plate 7 is provided at the end of the connecting piece 6 away from the third connecting rod 63. When the turntable 2 is rotated, the cam 3 rotates along with the turntable 2. Under the action of the outer wall of the cam 3 and the inner wall of the wheel groove 21, the sliding plate 5 is limited by the moving component, causing the moving block 4 to reciprocate linearly along the width direction of the worktable 1, thereby causing the sliding plate 5 to reciprocate linearly. During the rotation of the cam 3, the connecting member 6 is driven to move through the connecting shaft 31, the first connecting rod 61, the second connecting rod 62 and the third connecting rod 63. The connecting member 6 is affected by the limiting component on the sliding plate 5, causing the connecting member 6 to reciprocate linearly along the length direction of the worktable 1. Under the action of the sliding plate 5, the connecting member 6 causes the actuator plate 7 to make rectangular movements. The structure is simple and convenient for conveying materials.
[0024] Reference Figure 3The worktable 1 is equipped with a drive motor 11 that drives the turntable 2 to rotate. The output shaft of the drive motor 11 is coaxially and fixedly connected to the turntable 2. The drive motor 11 drives the turntable 2 and the cam 3 on the turntable 2 to rotate. The working speed of the entire rectangular motion mechanism is controlled by the rotation speed of the output shaft of the drive motor 11.
[0025] Reference Figure 1 and Figure 2 The moving assembly includes two slide rails 12, which are arranged along the width direction of the worktable 1. Two sliding blocks 51, which cooperate with the slide rails 12, are provided at the bottom of the sliding plate 5. Each sliding block 51 has a sliding groove that cooperates with the slide rail 12. The slide rail 12 is located within the sliding groove and is movably connected to the sliding block 51. When the cam 3 rotates and the connecting block moves under force, because the connecting block is fixedly connected to the sliding plate 5, the sliding plate 5 moves under force, and the sliding blocks 51 move along the slide rails 12, thereby limiting the movement of the sliding plate 5 so that it can only move along the width direction of the worktable 1.
[0026] Reference Figure 1 and Figure 2 The limiting component includes a limiting block 52, which is arranged along the length of the worktable 1. The limiting block 52 has a limiting groove that mates with the connecting member 6. The connecting member 6 is located within the limiting groove and is movably connected to the limiting block 52. During the rotation of the cam 3, the connecting member 6 is moved via the connecting shaft 31, the first connecting rod 61, the second connecting rod 62, and the third connecting rod 63. The force transmitted by the third connecting rod 63 moves the connecting member 6, and under the action of the limiting groove in the limiting block 52, the connecting member 6 moves along the limiting groove.
[0027] The implementation principle of a high-speed rectangular motion mechanism in this application embodiment is as follows: the turntable 2 is rotated, and the cam 3 rotates along with the turntable 2. Under the action of the outer wall of the cam 3 and the inner wall of the wheel groove 21, the sliding plate 5 is limited by the moving component, so that the moving block 4 moves linearly back and forth along the width direction of the worktable 1, thereby causing the sliding plate 5 to move linearly back and forth. During the rotation of the cam 3, the connecting member 6 is driven to move through the connecting shaft 31, the first connecting rod 61, the second connecting rod 62 and the third connecting rod 63. The connecting member 6 is acted upon by the limiting component on the sliding plate 5, so that the connecting member 6 moves linearly back and forth along the length direction of the worktable 1. Under the action of the sliding plate 5, the connecting member 6 causes the execution plate 7 to make rectangular motion. The structure is simple and convenient for conveying materials.
[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
