Description

Technical Field

[0001] This utility model relates to the field of engine piston manufacturing technology, specifically to an automatic clamping device and clamping components for engine piston manufacturing. Background Technology

[0002] As a major component of the engine, the piston reciprocates at high speed to meet the engine's power requirements. During the piston production process, the finished semi-finished products need to be placed on a transport vehicle. Once the transport vehicle is full of semi-finished piston products, the workers use a mobile transport vehicle to transport the semi-finished piston products to the next process.

[0003] According to a public announcement (CN116198975B) regarding an automatic clamping device and clamping component for engine piston production, the aforementioned application uses a U-shaped canvas belt as the clamping component to support and hold the piston. When the piston falls onto the canvas belt, the canvas belt, under the weight of the piston, automatically closes and tightens to surround the outer wall of the piston. At the same time, two extended crossbeams rotate synchronously towards the side where they close together, via pins around the corresponding hinge grooves. This allows for adjustment according to different sizes of piston semi-finished products, accommodating the clamping and transfer of piston semi-finished products of different sizes without the need for additional adjustment equipment, thus reducing production costs.

[0004] However, although the canvas belt surrounds the piston to some extent, the piston is wrapped in the canvas belt in a parallel state. If it encounters vibration, shaking, acceleration or deceleration during the transfer process, the piston is prone to rolling or sliding inside the canvas belt, causing its position to shift and fall out of the canvas belt, affecting the safety and reliability of the transfer. Utility Model Content

[0005] The purpose of this invention is to provide an automatic clamping device and clamping components for engine piston production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic clamping device for engine piston production, comprising a column, a turntable having multiple arrayed mounting slots on its side wall, a clamping component being provided inside the mounting slot, the clamping component comprising two sets of crossbeams, the two sets of crossbeams being symmetrically arranged, and the ends of the two sets of crossbeams being hinged to the inner wall of the mounting slot, an arc-shaped plate being fixedly connected to the side wall of the crossbeam, an arc-shaped groove being provided on the side wall of the arc-shaped plate, a slider being slidably connected to the inner wall of the arc-shaped groove, a rotating plate being fixedly connected to the side wall of the slider, the side wall of the end of the rotating plate being hinged to the side wall of the crossbeam, and a canvas belt being fixedly connected between the two sets of rotating plates.

[0007] Preferably, a dispersing component is provided on the side wall of the column. The dispersing component includes a bracket, which is fixedly connected to the side wall of the column. A through hole is opened on the surface of the bracket, and an electric telescopic rod is fixedly connected in the through hole. A mounting bracket is fixedly connected to the bottom end of the electric telescopic rod. A groove is opened on the surface of the mounting bracket, and two sets of symmetrically arranged extrusion blocks are slidably connected inside the groove. The two sets of extrusion blocks are threadedly connected by a bidirectional threaded rod.

[0008] Preferably, the bottom surfaces of the two sets of crossbeams are fixedly connected with extension rods, and multiple sets of arrayed railings are fixedly connected to the opposite side walls of the extension rods, with the railings on both sides arranged in a toothed, staggered pattern.

[0009] Preferably, the surface of the slider is provided with a through hole, and a positioning rod is slidably connected in the through hole, the end of the positioning rod being fixedly connected to the inner wall of the arc-shaped groove.

[0010] Preferably, the slider is elastically connected to the inner wall of the arc-shaped groove by a return spring.

[0011] Preferably, a second motor is fixedly connected to the side wall of the mounting bracket, the output shaft of the second motor passes through and is rotatably connected to the inner wall of the groove, and the output shaft of the second motor is fixedly connected to the end of the bidirectional threaded rod.

[0012] Preferably, a base is fixedly connected to the bottom surface of the column, and a placement groove is provided on the top of the column. A motor is fixedly connected inside the placement groove, and the output shaft of the motor is fixedly connected to the bottom surface of the turntable.

[0013] Compared with the prior art, the present invention provides an automatic clamping device and clamping components for engine piston production, which has the following advantages:

[0014] 1. The automatic clamping device and clamping components for engine piston production utilize the piston's gravity to bring two sets of crossbeams closer together. At this time, one end of the rotating plate rotates downward around the hinge point with the crossbeam. Guided by the positioning rod, the slider overcomes the spring force of the return spring and slides downward into the arc groove, causing the rotating plate and canvas belt to tilt towards the inside of the crossbeam. The piston slides towards the inside of the crossbeam as the canvas belt tilts, and its end fits against the interlocking rails. The canvas belt provides flexible clamping force, and the rails prevent the piston from shaking and falling during clamping, ensuring the safety and reliability of the transfer.

[0015] 2. The automatic clamping device and clamping components for engine piston production, by activating the dispersing component, extend the electric telescopic rod, adjust the height position of the mounting frame, and allow the extrusion block to enter between the two sets of crossbeams. The motor drives the bidirectional threaded rod to rotate, causing the two sets of extrusion blocks to move simultaneously in opposite directions. After the extrusion block contacts the opposite side wall of the crossbeam, it pushes the crossbeam to move synchronously, opening the crossbeams that have come together. As the degree of opening of the crossbeam increases, it overcomes the elastic force of the return spring and the weight of the piston. The rotating plate drives one side of the canvas belt to move upwards in the arc groove, causing the piston to slide off the surface of the canvas belt, completing the piston release, so that subsequent processing operations can be carried out.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: an automatic clamping device and clamping components for engine piston production, including a column 1, a base 11 fixedly connected to the bottom surface of the column 1, and a turntable 2 rotatably connected to the top surface of the column 1. The column 1 serves as the supporting structure for the entire device, fixing and supporting the turntable 2. The base 11 allows the entire device to be stably placed on the ground or other supporting surface. A placement groove 12 is provided on the top of the column 1, and a motor 13 is fixedly connected inside the placement groove 12. The output shaft of the motor 13 is fixedly connected to the bottom surface of the turntable 2. Multiple sets of arrayed mounting grooves 21 are provided on the side wall of the turntable 2, and clamping components 3 are arranged inside the mounting grooves 21. The placement groove 12 is used to install the motor 13, and the output shaft of the motor 13 provides power for the rotation of the turntable 2, thereby driving the clamping components 3 to rotate and realizing the transfer of the piston.

[0022] like Figures 2-3 As shown, the clamping component 3 includes two sets of crossbeams 31, which are symmetrically arranged and whose ends are hinged to the inner wall of the mounting groove 21. The crossbeams 31 provide support for the entire clamping component 3. An arc-shaped plate 32 is fixedly connected to the side wall of the crossbeam 31. An arc-shaped groove 33 is provided on the side wall of the arc-shaped plate 32. A slider 34 is slidably connected to the inner wall of the arc-shaped groove 33. A rotating plate 35 is fixedly connected to the side wall of the slider 34. The side wall of the end of the rotating plate 35 is hinged to the side wall of the crossbeam 31. The arc-shaped groove 33 provides a track for the slider 34 to slide, so that the rotating plate 35 can rotate at an angle along the hinge point with the crossbeam 31. A canvas belt 36 is fixedly connected between the two sets of rotating plates 35. The canvas belt 36 is used to wrap the piston, providing a flexible clamping force to prevent the piston from being damaged during transportation. The slider 34 has a through hole on its surface, and a positioning rod 37 is slidably connected in the through hole. The end of the positioning rod 37 is fixedly connected to the inner wall of the arc-shaped groove 33. The positioning rod 37 is used to guide the slider 34, limit the sliding range of the slider 34, and ensure the accuracy and stability of its movement. The slider 34 and the inner wall of the arc-shaped groove 33 are elastically connected by a return spring 38. The return spring 38 provides elastic force, allowing the slider 34 to return to its initial position when no external force is applied, so that the canvas belt 36 remains parallel before wrapping the piston.

[0023] like Figures 2-3 As shown, extension rods 39 are fixedly connected to the bottom surfaces of the two sets of crossbeams 31. Multiple arrays of railings 310 are fixedly connected to the opposite side walls of the extension rods 39, with the railings 310 arranged in a toothed, staggered pattern. When the two sets of crossbeams 31 approach each other, the railings 310 interlock and contact the end of the piston, preventing the piston from shaking and falling off during clamping.

[0024] In summary, when the piston falls, the canvas belt 36 wraps around it, providing a flexible clamping force. Under the weight of the piston, the two sets of crossbeams 31 move closer together. One end of the rotating plate 35 rotates downward at the hinge point with the crossbeam 31. Under the guidance of the positioning rod 37, the slider 34 slides downward toward the arc-shaped groove 33 and overcomes the elastic support of the return spring 38, causing the rotating plate 35 and the canvas belt 36 to tilt toward the inside of the crossbeam 31. The piston tilts along with the canvas belt 36 and slides toward the inside of the crossbeam 31, with its end fitting against the interlocking railings 310, thus preventing the piston from shaking and falling during the clamping process.

[0025] like Figure 2 , Figure 4As shown, a dispersing component 4 is provided on the side wall of the column 1. The dispersing component 4 is used to open the closely spaced crossbeams 31. The dispersing component 4 includes a bracket 41, which is fixedly connected to the side wall of the column 1. The surface of the bracket 41 has a through hole, and an electric telescopic rod 42 is fixedly connected to the through hole. The bottom end of the electric telescopic rod 42 is fixedly connected to a mounting bracket 43. The bracket 41 serves to support and position the electric telescopic rod 42. The electric telescopic rod 42 can extend and retract as needed, and the height position of the mounting bracket 43 can be adjusted by extending or shortening, so that the extrusion block 45 can enter between the two sets of crossbeams 31. The surface of the mounting bracket 43 has a groove 44, and two sets of symmetrically arranged extrusion blocks 45 are slidably connected inside the groove 44. The groove 44 provides a sliding track for the extrusion block 45, allowing the extrusion block 45 to slide in a specific direction within the groove 44.

[0026] like Figure 2 , Figure 4 As shown, the two sets of extrusion blocks 45 are threaded together by a bidirectional threaded rod 46. A second motor 47 is fixedly connected to the side wall of the mounting bracket 43. The output shaft of the second motor 47 passes through and is rotatably connected to the inner wall of the groove 44. The output shaft of the second motor 47 is fixedly connected to the end of the bidirectional threaded rod 46. Driven by the second motor 47, the bidirectional threaded rod 46 rotates, causing the two sets of extrusion blocks 45 threaded together to move simultaneously in opposite directions. Through the contact between the extrusion blocks 45 and the opposite side walls of the crossbeam 31, the crossbeam 31 is pushed to move synchronously, opening the crossbeam 31 that has come together. As the degree of opening increases, it overcomes the elastic force of the return spring 38 and the weight of the piston, causing the rotating plate 35 to move one side of the canvas belt 36 upwards towards the arc-shaped groove 33, thereby causing the piston to slide off the surface of the canvas belt 36.

[0027] In this invention, during use, the automatic clamping device is stably placed in a suitable working position via the base 11. The motor 13 is started, causing the turntable 2 to rotate to a suitable initial position, so that the canvas belt 36 of one set of clamping components 3 is directly below the piston discharge port, ready to receive the piston.

[0028] As the engine piston falls from the discharge port onto the canvas belt 36, its weight causes the two sets of crossbeams 31 to move closer together. At this point, one end of the rotating plate 35 rotates downward about the hinge point with the crossbeam 31. Guided by the positioning rod 37, the slider 34 overcomes the elastic force of the return spring 38 and slides downward into the arc-shaped groove 33. This causes the rotating plate 35 and the canvas belt 36 to tilt inward toward the crossbeam 31. The piston slides inward toward the crossbeam 31 as the canvas belt 36 tilts, and its end comes into contact with the interlocking rails 310. The canvas belt 36 provides a flexible clamping force, and the rails 310 prevent the piston from shaking or falling during clamping, thus achieving stable clamping of the piston.

[0029] Motor 13 operates continuously, driving turntable 2 to rotate and transferring the clamping component 3, which holds the piston, to the designated processing or handling position. During this process, the canvas belt 36 and the railing 310 maintain stable clamping of the piston, ensuring that the piston will not fall or be damaged during transfer.

[0030] Once the clamping component 3 rotates to the designated position, the dispersing component 4 is activated. First, the electric telescopic rod 42 extends, adjusting the height of the mounting bracket 43 so that the extrusion block 45 enters between the two sets of crossbeams 31. Then, the motor 47 drives the bidirectional threaded rod 46 to rotate, causing the two sets of extrusion blocks 45 to move simultaneously in opposite directions. After the extrusion block 45 contacts the opposite sidewall of the crossbeam 31, it pushes the crossbeam 31 to move synchronously, opening the crossbeams 31 that have come together. As the degree of opening of the crossbeam 31 increases, overcoming the elasticity of the return spring 38 and the weight of the piston, the rotating plate 35 moves one side of the canvas belt 36 upwards towards the arc-shaped groove 33, causing the piston to slide off the surface of the canvas belt 36, completing the piston release for subsequent processing operations.

[0031] After completing one cycle of piston clamping, transfer, and release, motor 13 rotates turntable 2 again, rotating the next set of empty clamping components 3 to below the piston discharge port, repeating the above steps to achieve continuous automatic clamping and transfer of the engine piston.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
