Description

Technical Field

[0001] This invention belongs to the field of conveying equipment technology, and specifically relates to a camshaft conveying device. Background Technology

[0002] Camshafts are commonly used workpieces, and camshaft transfer and conveying are common operational methods. Existing camshaft transfer and conveying equipment has a narrow range of applicable workpieces and cannot meet the requirements of large-scale industrial production. In addition, existing conveyors lack the necessary devices to handle impurities and debris on the workpiece surface, and the camshafts also lack necessary positioning devices during the conveying process, making it difficult to accurately clamp the workpieces during transport.

[0003] Existing patent number (CN207748410U) discloses a camshaft conveyor, including a frame, a support plate on the top of the frame, a conveyor chain mounted on the top surface of the frame, brackets evenly distributed on the conveyor chain, workpiece placement slots on the brackets, and a positioning device for positioning the workpieces on the brackets on the conveyor chain. This conveyor transports camshafts via the chain; simultaneously, the positioning device positions the camshafts during transport, ensuring that the camshafts are positioned to the same specifications.

[0004] However, the above-mentioned application requires the conveyor to be repeatedly started and stopped each time it is clamped, which affects the life of the equipment. Furthermore, the accuracy of the plate chain conveyor is difficult to guarantee, while the clamping accuracy requirement of the camshaft is high, which can easily cause the camshaft to deviate when it is clamped. Summary of the Invention

[0005] The purpose of this invention is to provide a camshaft conveying device to solve the problem of...

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] A camshaft conveying device includes a support frame and a lifting frame. A drive motor is mounted on the support frame, and multiple rocker arms are symmetrically arranged on both sides of the support frame. The output shaft of the drive motor is drivenly connected to one of the rocker arms, and the two sides of the lifting frame are rotatably connected to the multiple rocker arms.

[0008] The rocker arm includes a first rotating rod and a rocker arm. A fixed seat is fixedly connected to the support frame. The first rotating rod is rotatably mounted on the fixed seat. The output shaft of the drive motor is connected to the first rotating rod in a transmission manner. The rocker arm is fixedly connected to the free end of the first rotating rod. A second rotating rod is rotatably mounted on the rocker arm. The second rotating rod is rotatably mounted on the lifting frame.

[0009] The upper ends of the support frame and the lifting frame are each equipped with a plurality of limit seats at equal intervals. The limit seats are used to support the camshaft and prevent the camshaft from rotating.

[0010] Further specifying, it also includes a limiting mechanism, which includes a limiting plate with a sliding rail. The lifting frame includes a first frame and a first base plate. The second rotating rod is rotatably mounted on the first frame. A first sliding groove is formed at the lower end of the first base plate. The first frame is laterally slidably mounted in the first sliding groove. The limiting plate has a sliding rail. A connecting rod is fixedly connected to the first base plate. A guide rod is fixedly connected to the connecting rod and slidably mounted in the sliding rail. When the lifting frame lowers or raises the camshaft, the limiting plate slides vertically along the sliding rail. This structural design, through the cooperation of the sliding rail and the guide rod, ensures that when the lifting frame raises the camshaft on the support frame, it moves linearly upward. After the camshaft disengages from the limiting seat, the guide rod enters the arc-shaped rail until the camshaft is above the next set of limiting seats. Then, the lifting frame moves linearly downward, preventing the camshaft from colliding with the limiting seats during transmission and causing misalignment.

[0011] Further specifying, the upper end of the first base plate has a second sliding groove, and a first support plate is fixedly connected to the first base plate within the second sliding groove. A first screw is rotatably mounted on the first support plate, and two first sliders are screwed onto the first screw at intervals. A first mounting plate is slidably mounted between the two first screws and the two first sliders. The first mounting plate is slidably mounted within the second sliding groove, and the corresponding limiting seat is fixedly connected to the first mounting plate. This structural design, through the first screw and the first mounting plate, allows the position of the limiting seat to be adjusted, and the first mounting plate to be detachable, enabling the replacement of the corresponding limiting seat for different specifications of camshafts, thereby accommodating various camshaft specifications.

[0012] Further defined, the sliding track comprises two straight segments and two arc segments. The two arc segments are located at the upper and lower ends of the limiting seat, respectively, and the two straight segments are located at the left and right ends of the limiting seat, respectively. A tangent segment connects the arc segments and the straight segments, and the radius of the arc segment is the same as the rotation radius of the rocker arm. This structural design, by setting the arc segments and straight segments, allows the lifting frame to move upward along the straight segments when lifting the camshaft on the support frame. After the camshaft disengages from the limiting seat, the guide rod enters the arc segment until the camshaft is above the next set of limiting seats. Then, the lifting frame moves downward along the straight segments and re-enters the arc segments, completing a single rotation. This prevents the camshaft from colliding with the limiting seat during transmission, thus avoiding misalignment.

[0013] Furthermore, a guide plate is fixedly connected to the support frame, and one end of the camshaft rests against the guide plate. This structural design, by setting the guide plate, provides lateral positioning of the camshaft during transmission.

[0014] Furthermore, an electromagnet is mounted on the guide plate, which is used to correct the lateral position of the camshaft. This structural design, by placing an electromagnet at the end of the transmission device, uses a battery to briefly attract the camshaft, thereby ensuring the lateral positioning of the camshaft, and then uses a mechanical gripper for clamping, resulting in more accurate positioning.

[0015] Further specifying, the support frame has a third sliding groove on the side away from the guide plate. A second support plate is fixedly connected to the support frame within the second sliding groove. A second screw is rotatably mounted on the second support plate. Two second sliders are screwed onto the second screw at intervals. A second mounting plate is slidably mounted between the two second screws and the two second sliders. The second mounting plate is slidably mounted within the second sliding groove. The corresponding limiting seat is fixedly connected to the second mounting plate. This structural design, through the second screw and the second mounting plate, allows the position of the limiting seat to be adjusted, and the second mounting plate to be detachable. This allows for the replacement of the corresponding limiting seat for different camshaft specifications, thus accommodating various camshaft sizes.

[0016] Furthermore, the support frame has a mounting groove on the side near the guide plate, and a third mounting plate is bolted to the support frame within the mounting groove. The corresponding limiting seat is mounted on the third mounting plate. This structural design, by providing a detachable third mounting plate, allows for the replacement of the corresponding limiting seat for different camshaft specifications, thus accommodating various camshaft sizes.

[0017] The invention employing the above technical solution has the following advantages:

[0018] 1. Through the cooperation of the support frame, lifting frame, rocker arm and limit seat, the lifting frame is intermittently fed by multiple rocker arms. There is no need to start and stop repeatedly during the transmission process, and the clamping point of the camshaft is fixed, so it is not easy to deviate during clamping.

[0019] 2. Through the cooperation of the sliding rail and the guide rod, when the lifting frame lifts the camshaft on the support frame, the lifting frame moves upward along the straight section. After the camshaft disengages from the limit seat, the guide rod enters the arc section. When the camshaft is above the next set of limit seats, the lifting frame moves downward along the straight section and enters the arc section again to complete a single rotation. This prevents the camshaft from colliding with the limit seat during transmission and causing misalignment.

[0020] 3. Through the mutual cooperation of the first screw, the second screw, the first mounting plate, the second mounting plate and the third mounting plate, the corresponding limit seats can be replaced or adjusted for camshafts of different specifications, thereby adapting to camshafts of various specifications.

[0036] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0037] like Figures 1-7 As shown, a camshaft conveying device of the present invention includes a support frame 1 and a lifting frame 2. A drive motor 3 is installed on the support frame 1, and multiple rocker arms 4 are symmetrically arranged on both sides of the support frame 1. The output shaft of the drive motor 3 is connected to one of the rocker arms 4 in a transmission connection. Both sides of the lifting frame 2 are rotatably connected to the multiple rocker arms 4. A transmission plate is fixedly installed on the top of the support frame 1.

[0038] The rocker arm 4 includes a first rotating rod 41 and a rocker arm 42. A fixed seat 11 is fixedly connected to the support frame 1. The first rotating rod 41 is rotatably mounted on the fixed seat 11. The output shaft of the drive motor 3 is connected to the first rotating rod 41 in a transmission connection. The rocker arm 42 is fixedly connected to the free end of the first rotating rod 41. A second rotating rod 43 is rotatably mounted on the rocker arm 42. The second rotating rod 43 is rotatably mounted on the lifting frame 2.

[0039] Multiple limit seats 5 are installed at equal intervals on the upper ends of the support frame 1 and the lifting frame 2. The limit seats 5 are used to support the camshaft 6 and prevent the camshaft 6 from rotating.

[0040] See Figure 2 and Figure 4 It also includes a limiting mechanism, which includes a limiting plate 7 with a sliding rail. The lifting frame 2 includes a first frame 21 and a first base plate 22. A second rotating rod 43 is rotatably mounted on the first frame 21. A first sliding groove is provided at the lower end of the first base plate 22. The first frame 21 is slidably mounted laterally in the first sliding groove. A sliding rail is provided on the limiting plate 7. A connecting rod 23 is fixedly connected to the first base plate 22. A guide rod 24 is fixedly connected to the connecting rod 23 and is slidably mounted in the sliding rail. When the lifting frame 2 lowers or raises the camshaft 6, the limiting plate 7 slides vertically along the sliding rail. With this structural design, through the cooperation of the sliding track and the guide rod 24, when the lifting frame 2 lifts the camshaft 6 on the support frame 1, the lifting frame 2 moves straight upward. After the camshaft 6 disengages from the limit seat 5, the guide rod 24 enters the arc track. When the camshaft 6 is above the next set of limit seats 5, the lifting frame 2 moves straight downward, preventing the camshaft 6 from colliding with the limit seat 5 during transmission and causing misalignment.

[0041] See Figure 3 The upper end of the first base plate 22 is provided with a second sliding groove. A first support plate 25 is fixedly connected to the first base plate 22 within the second sliding groove. A first screw 26 is rotatably mounted on the first support plate 25. Two first sliders 27 are screwed onto the first screw 26 at intervals. A first mounting plate 28 is slidably mounted between the two first screws 26 and the two first sliders 27. The first mounting plate 28 is slidably mounted within the second sliding groove. A corresponding limiting seat 5 is fixedly connected to the first mounting plate 28. This structural design, through the first screw 26 and the first mounting plate 28, allows the position of the limiting seat 5 to be adjusted, and the first mounting plate 28 to be detachable. The corresponding limiting seat 5 can be replaced for different specifications of camshafts 6, thus adapting to various specifications of camshafts 6.

[0042] See Figure 3 The sliding track includes two straight segments 71 and two curved segments 72. The two curved segments 72 are located at the upper and lower ends of the limiting seat 5, respectively, and the two straight segments 71 are located at the left and right ends of the limiting seat 5, respectively. A tangent segment 73 connects the curved segments 72 and the straight segments 71. The radius of the curved segment 72 is the same as the rotation radius of the rocker arm 42. With this structural design, by setting the curved segments 72 and the straight segments 71, when the lifting frame 2 lifts the camshaft 6 on the support frame 1, the lifting frame 2 moves upward along the straight segments 71. After the camshaft 6 disengages from the limiting seat 5, the guide rod 24 enters the curved segments 72 until the camshaft 6 is above the next set of limiting seats 5. Then, the lifting frame moves downward along the straight segments 71 and re-enters the curved segments 72, completing a single rotation. This prevents the camshaft 6 from colliding with the limiting seats 5 during transmission and causing misalignment.

[0043] See Figure 1 A guide plate 12 is fixedly connected to the support frame 1, and one end of the camshaft 6 rests against the guide plate 12. This structural design, by setting the guide plate 12, provides lateral positioning for the camshaft 6 during transmission.

[0044] See Figure 1 An electromagnet 13 is installed on the guide plate 12. The electromagnet 13 is used to correct the lateral position of the camshaft 6. This structural design, by setting the electromagnet 13 at the end of the transmission device, uses the battery iron to briefly attract the camshaft 6, thereby ensuring the lateral positioning of the camshaft 6. Then, the mechanical claw is used for clamping, making the positioning more accurate.

[0045] See Figure 3A third sliding groove is provided on the side of the support frame 1 away from the guide plate 12. A second support plate 14 is fixedly connected to the support frame 1 within the second sliding groove. A second screw 15 is rotatably mounted on the second support plate 14. Two second sliders 16 are screwed onto the second screw 15 at intervals. A second mounting plate 17 is slidably mounted between the two second screws 15 and the two second sliders 16. The second mounting plate 17 is slidably mounted within the second sliding groove. A corresponding limiting seat 5 is fixedly connected to the second mounting plate 17. This structural design, through the second screw 15 and the second mounting plate 17, allows the position of the limiting seat 5 to be adjusted, and the second mounting plate 17 to be detachable. The corresponding limiting seat 5 can be replaced for different specifications of camshafts 6, thus adapting to various specifications of camshafts 6.

[0046] See Figure 3 A mounting groove is provided on the side of the support frame 1 near the guide plate 12. A third mounting plate 18 is bolted to the support frame 1 within the mounting groove, and a corresponding limiting seat 5 is mounted on the third mounting plate 18. This structural design, by providing a detachable third mounting plate 18, allows for the replacement of the corresponding limiting seat 5 for different specifications of camshafts 6, thereby accommodating various specifications of camshafts 6.

[0047] The usage principle and method of this embodiment are as follows:

[0048] According to the specifications of the camshaft 6, different first mounting plates 28, second mounting plates 17 and third mounting plates 18 are replaced to replace different limit seats 5. Then, the first screw 26 and the second screw 15 are used for adjustment so that the first slider 27 or the second slider 16 drives the corresponding limit seat 5 to move, thereby adjusting the distance between the limit seats 5 in the same row.

[0049] After the adjustment is completed, place the camshaft 6 at the feed end of the conveying device. At this time, the camshaft 6 is located on the limiting seat 5 of the support frame 1.

[0050] Start drive motor 3, rocker arm 4 rotates clockwise, see reference. Figure 2 and Figure 4 In the initial position, both the rocker arm 4 and the lifting frame 2 are parallel to the support frame 1, and the guide rod 24 is located on the straight section 71. After the rocker arm 4 is lifted upwards, refer to... Figure 5 and Figure 6 Due to the limitation of the straight section, the lifting frame 2 vertically lifts the camshaft 6 on the support frame 1, and the camshaft 6 disengages from the transmission plate. (See reference...) Figure 7 Guide rod 24 enters arc segment 72;

[0051] When the rocker arm approaches the support frame 1 four times, the guide rod 24 re-enters the straight section 71, and the camshaft 6 descends in a straight line. When the rocker arm 4 rotates 180°, the camshaft 6 engages with the limit seat 5 on the support frame 1. The rocker arm 4 continues to rotate 180° back to the starting position. Multiple rotations form intermittent feeding. When the camshaft 6 reaches the clamping point, the battery iron briefly attracts the camshaft 6, thereby ensuring the lateral positioning of the camshaft 6.

The specific embodiments described are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
