Description

Technical Field

[0001] This invention relates to the field of gripping device technology, specifically to an automated mechanical gripping device for machining and manufacturing. Background Technology

[0002] With the development of science and technology, mechanical automation plays an increasingly important role in many fields. In the production process, anything that changes the shape, size, position and properties of the production object is a major part of the production process. Nowadays, many factory workshops use a large number of automated equipment to replace manual labor, which is very convenient and greatly improves work efficiency. Mechanical automated gripping devices are used in the mechanical processing and manufacturing process.

[0003] A mechanical automated gripping device disclosed in CN211137176U uses a servo motor to drive a first gear to rotate. The first gear drives two first racks to move simultaneously. The first racks drive corresponding moving seats to move. The moving seats slide in a fixed hole and drive an adjusting column to move. This causes the adjusting column to drive a corresponding buffer clamping plate. The two buffer clamping plates clamp the item. The adjusting column continues to move and presses a compression spring. The elasticity of the compression spring can drive the buffer clamping plates to clamp and fix the item. By rotating a rotating rod, the rotating rod drives a second gear to rotate. The second gear drives two second racks to move. The second racks drive a corresponding connecting rod to move. The connecting rod drives a corresponding limiting seat to move. The limiting seat presses a corresponding spring and slides out of the limiting groove, thus releasing the fixing of the adjusting column. Moving the adjusting column allows it to slide in the fixed groove, thus adjusting the extension distance of the gripping device. Releasing the rotating rod causes the spring's elasticity to drive the limiting seat into the limiting groove, thus fixing the position of the adjusting column in the fixed groove.

[0004] In a mechanical automated gripping device for machining and manufacturing disclosed in CN216302605U, a second motor is started, which drives the threaded rod to rotate, thereby allowing the moving block to move left and right on the surface of the slide bar, and thus moving the mechanical claw left and right. A hydraulic cylinder is started to push the mechanical claw up and down. A third motor is started, which drives the worm gear to rotate, and the worm gear transmits to the worm wheel, which rotates to drive the mechanical claw to open or close. After the machine stops operating, the first motor is started according to the time set by the controller. The first motor drives the first gear to rotate, and with the cooperation of the rack and pinion, it drives the lubrication mechanism to move on the surface of the slide bar. At the same time, the micro oil pump is started, the electronic flow valve is opened, and the lubricating oil in the oil box flows into the upper oil passage of the upper slide bar seat, then into the lower oil passage of the lower slide bar seat, and is discharged from the oil outlet to lubricate the surface of the slide bar. The electronic flow valve automatically closes after detecting that the amount of lubricating oil is sufficient.

[0005] The above solution also has some problems in use: the shape of the gripping component is fixed and requires manual adjustment, which is time-consuming. When gripping workpieces of different sizes and shapes, the contact area of ​​gripping is insufficient or the gripping specifications are not easy to adjust. At the same time, the mechanical friction between the drive components is large during long-term operation, which requires lubrication. However, lubrication requires adjusting each valve individually, which is not convenient for quick and comprehensive lubrication.

[0006] Therefore, we propose an automated mechanical gripping device for machining and manufacturing to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an automated mechanical gripping device for machining and manufacturing, to solve the problems mentioned above. In the existing automated mechanical gripping devices on the market, the gripping parts have fixed shapes and require individual manual adjustment, which is time-consuming. When gripping workpieces of different sizes and shapes, the gripping contact area is insufficient or the gripping specifications are not easy to adjust. At the same time, the friction between the mechanical parts is large during long-term operation, which requires lubrication. However, lubrication requires adjusting each valve individually, which is not convenient for quick and comprehensive lubrication.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a mechanical automated gripping device for machining and manufacturing, comprising a mounting plate, wherein a boom is connected to the top of the mounting plate, and the bottom of the boom is connected to the center of the top surface of the mounting plate via a vertical rod, and a connecting frame is fixed to the outside of the boom, wherein the bottom of the connecting frame is rotatably connected to the top of the mounting plate.

[0009] Also includes:

[0010] The bottom of the mounting plate is provided with a horizontal groove, and a first reciprocating screw is connected to the bearing in the horizontal groove, and a moving block is symmetrically threaded on the first reciprocating screw.

[0011] The bottom bearing of the movable block is connected to a second reciprocating screw, and the bottom of the second reciprocating screw is threadedly connected to the top of the gripper, and the top of the gripper is slidably connected to a limit post, while the top of the limit post is fixed to the bottom of the movable block.

[0012] A vertical rod is connected to the bottom center of the boom via a through bearing, and the bottom of the vertical rod is connected to the top of the mounting plate.

[0013] The top of the mounting plate has symmetrical bearings on the left and right sides connected to gears, and the middle of the gears is connected to the switch valve through a sprocket mechanism. The switch valve is installed on the outlet at the bottom of the storage box, and the outlet of the storage box is connected to the lubrication channel through a connecting pipe. The lubrication channel is opened on the inner wall of the moving block.

[0014] Preferably, a first motor is installed on the outside of the right side of the mounting plate, and the output end of the first motor is connected to a crossbar. The crossbar is connected to the left and right sides inside the mounting plate through a bearing, and the middle part of the crossbar is connected to a first reciprocating screw through a first ratchet assembly. This way, after the first motor drives the crossbar to rotate, the crossbar will drive the first reciprocating screw to rotate through the first ratchet assembly.

[0015] Preferably, the first reciprocating screw forms a unidirectional rotation structure through the crossbar and the first ratchet assembly, and the moving block forms a horizontal movement structure through the first reciprocating screw and the cross groove, so that the first reciprocating screw will drive the moving block to slide after rotation.

[0016] Preferably, the left and right ends of the crossbar are connected to the rotating rod below via a sprocket mechanism, and the rotating rod is connected to the bottom of the mounting plate via a through bearing. The end of the rotating rod is connected to the telescopic rod via a second ratchet assembly, and the telescopic rod is connected to the bottom of the mounting plate via a bearing. At the same time, the end of the telescopic rod is connected to the top of the second reciprocating screw via a bevel gear connector, so that the crossbar drives the rotating rod to rotate via the sprocket mechanism, the rotating rod drives the telescopic rod to rotate via the second ratchet assembly, and the telescopic rod drives the second reciprocating screw to rotate via the bevel gear connector.

[0017] Preferably, the telescopic rod drives the second reciprocating screw on the moving block to rotate synchronously, and the sliding space between the limiting post and the gripper is a rectangular structure. The gripper forms a vertical sliding structure through the second reciprocating screw and the limiting post. Moreover, the gripper is set to an "L" shape, so that when the second reciprocating screw drives the gripper to move, the limiting post will maintain the stability of the gripper.

[0018] Preferably, the gripper has grooves evenly spaced on its side, and a buffer plate is connected in the groove. The buffer plate is configured as a "T" shape, and a spring is installed between the buffer plate and the groove. The buffer plate forms a clamping and buffering structure through the groove and the spring, so that when the buffer plate comes into contact with the workpiece, it will slide in the groove and compress the spring.

[0019] Preferably, a second motor is embedded inside the boom, and the output end of the second motor is connected to a vertical rod. The bottom of the vertical rod is connected to the top of the mounting plate through a third ratchet assembly, so that after the second motor drives the vertical rod to rotate, the vertical rod will drive the mounting plate to rotate through the third ratchet assembly.

[0020] Preferably, the upper outer side of the vertical rod is connected to the equidistant toothed disc via a fourth ratchet assembly, and the outer side of the equidistant toothed disc has protruding teeth distributed at equal intervals. Furthermore, gears are connected to both the left and right sides of the equidistant toothed disc, so that after the vertical rod drives the equidistant toothed disc to rotate via the fourth ratchet assembly, the equidistant toothed disc will drive the gears to rotate.

[0021] Preferably, a torsion spring is installed between the bottom of the gear and the top of the mounting plate, and the gear forms a reciprocating rotation structure through the equidistant toothed disc and the torsion spring. The gear drives the switch valve through the sprocket mechanism to form a switching structure, so that the rotation of the gear will reverse the torsion spring, thereby driving the switch valve to open and close through the sprocket mechanism.

[0022] Compared with existing technologies, the beneficial effects of the automated mechanical gripping device for machining and manufacturing of the present invention are as follows: During use, the gripping component is moved open and closed by the moving block, thereby adjusting the gripping width. Furthermore, the rotation of the second reciprocating screw allows the gripping component to slide up and down, thus adjusting the gripping height. The buffer plate and spring reduce the impact on the gripped workpiece, making it suitable for gripping workpieces of various specifications. Adjustment is convenient. The vertical rod can drive the entire mounting plate to rotate, thereby adjusting the gripping angle. Moreover, the reciprocating rotation of the gears can automatically open and close the switching valve, thereby delivering lubricating oil to the lubrication channel. The entire working area is lubricated through the movement of the moving block. Specific details are as follows:

[0023] 1. After the first motor drives the crossbar to rotate in the forward direction, the crossbar will drive the first reciprocating screw to rotate through the first ratchet assembly. After the first reciprocating screw rotates, it will drive the moving block to slide. The moving block will drive the gripper to move synchronously, thereby adjusting the gripping width. When the crossbar rotates in the reverse direction, it will drive the rotating rod to rotate through the sprocket mechanism. The rotating rod will drive the telescopic rod to rotate through the second ratchet assembly. After the telescopic rod rotates, it will drive the second reciprocating screw to rotate through the bevel gear connector. After the second reciprocating screw rotates, with the cooperation of the limiting post, the gripper will slide vertically, thereby adjusting the gripping height. This allows for the gripping of workpieces of different specifications. The adjustment is convenient and quick, giving the gripping device good adaptability.

[0024] 2. After the second motor drives the vertical rod to rotate forward, the vertical rod will drive the mounting plate to rotate via the third ratchet assembly, thereby adjusting the gripping angle. After the vertical rod rotates in the reverse direction, it will drive the equidistant toothed disc to rotate via the fourth ratchet assembly. The equidistant toothed disc will intermittently mesh with the outer gear, thereby driving the gear to rotate. After the gear rotates, it will reverse the torsion spring. When the equidistant toothed disc and the gear are not meshing, the torsion spring will drive the gear to rotate back, thereby causing the gear to reciprocate. After the gear rotates, it will drive the switch valve to open and close via the sprocket mechanism, thereby evenly delivering lubricating oil to the lubrication channel inside the moving block, thus lubricating the moving parts. As the moving block slides, it can lubricate the entire moving area, reduce wear, and facilitate operation. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-8 This invention provides a technical solution: an automated mechanical gripping device for machining and manufacturing, comprising a mounting plate 1, with a lifting arm 2 connected to the top of the mounting plate 1, and the bottom of the lifting arm 2 connected to the center of the top surface of the mounting plate 1 via a vertical rod 20. A connecting frame 3 is fixed to the outer side of the lifting arm 2, and the bottom of the connecting frame 3 is rotatably connected to the top of the mounting plate 1. Figure 1 As shown, during use, the outer side of the boom 2 is connected to the mounting plate 1 via the connecting frame 3. The connecting frame 3 can rotate on the top of the mounting plate 1, and the bottom of the boom 2 is connected to the top of the mounting plate 1 via the vertical rod 20.

[0036] The bottom of the mounting plate 1 has a horizontal groove 8, and a first reciprocating screw 7 is connected to the bearing in the horizontal groove 8. A moving block 9 is symmetrically threaded onto the first reciprocating screw 7. A first motor 4 is mounted on the outside right side of the mounting plate 1, and the output end of the first motor 4 is connected to a crossbar 5. The crossbar 5 passes through a bearing and connects to the left and right sides inside the mounting plate 1. The middle part of the crossbar 5 is connected to the first reciprocating screw 7 via a first ratchet assembly 6. The first reciprocating screw 7 forms a unidirectional rotation structure through the crossbar 5 and the first ratchet assembly 6. The moving block 9 forms a horizontal movement structure through the first reciprocating screw 7 and the horizontal groove 8. Figure 1 As shown, when gripping, the first motor 4 on the mounting plate 1 is started, and the first motor 4 will drive the crossbar 5 to rotate. After the crossbar 5 rotates, it will drive the first reciprocating screw 7 to rotate in the cross groove 8 through the first ratchet assembly 6 on the outer side of the middle. After the first reciprocating screw 7 rotates, it will drive the moving block 9 to move relative to each other. The movement of the moving block 9 will drive the gripping component 10 to move synchronously, thereby adjusting the gripping width.

[0037] The bottom bearing of the movable block 9 is connected to a second reciprocating screw 14, and the bottom of the second reciprocating screw 14 is threadedly connected to the top of the gripper 10. The top of the gripper 10 is slidably connected to a limit post 15, and the top of the limit post 15 is fixed to the bottom of the movable block 9. The left and right ends of the crossbar 5 are connected to the rotating rod 11 below via a sprocket mechanism. The rotating rod 11 is connected to the bottom of the mounting plate 1 via a bearing, and the end of the rotating rod 11 is connected to the telescopic rod 13 via a second ratchet assembly 12. The telescopic rod 13 is bearing-connected to the bottom of the mounting plate 1, and the end of the telescopic rod 13 is connected to the top of the second reciprocating screw 14 via a bevel gear connector. The telescopic rod 13 drives the second reciprocating screw 14 on the movable block 9 to rotate synchronously. The sliding space between the limit post 15 and the gripper 10 is rectangular, and the gripper 10 forms a vertical sliding structure through the second reciprocating screw 14 and the limit post 15. Figure 1-3 As shown, after the first motor 4 drives the crossbar 5 to reverse, the first ratchet assembly 6 is in a disengaged state. The two sides of the crossbar 5 will drive the rotating rod 11 to rotate through the sprocket mechanism. After the rotating rod 11 rotates, it will drive the telescopic rod 13 to rotate through the second ratchet assembly 12. After the telescopic rod 13 rotates, it will drive the second reciprocating screw 14 to rotate through the bevel gear connector. After the second reciprocating screw 14 rotates, it will drive the gripper 10 to move vertically. The limiting post 15 can maintain the stability of the gripper 10 when it moves. After the gripper 10 moves, the gripping height can be adjusted, so as to adapt to workpieces of different sizes.

[0038] The gripper 10 is configured with an "L"-shaped structure. Grooves 16 are evenly spaced on the side of the gripper 10, and buffer plates 17 are connected to the grooves 16. The buffer plates 17 are configured with a "T"-shaped structure, and springs 18 are installed between the buffer plates 17 and the grooves 16. The buffer plates 17, through the grooves 16 and the springs 18, form a clamping and buffering structure. Figure 1 and Figure 3-4 As shown, when the gripper 10 grips, the buffer plate 17 will flexibly adjust according to the shape of the workpiece, so that the buffer plate 17 can better fit the outside of the workpiece. When the buffer plate 17 is subjected to force, it will compress the spring 18 and slide inside the groove 16, thereby avoiding hard contact and damage to the workpiece.

[0039] A second motor 19 is embedded inside the boom 2, and the output end of the second motor 19 is connected to a vertical rod 20. The bottom of the vertical rod 20 is connected to the top of the mounting plate 1 via a third ratchet assembly 21. The vertical rod 20 is connected to the middle of the bottom surface of the boom 2 via a bearing, and the bottom of the vertical rod 20 is connected to the top of the mounting plate 1. Figure 1 and Figure 5As shown, when the angle needs to be adjusted during the gripping process, the second motor 19 in the boom 2 is started. The second motor 19 will drive the vertical rod 20 to rotate. After the vertical rod 20 rotates, it will drive the mounting plate 1 to rotate through the third ratchet assembly 21, thereby adjusting to the appropriate gripping angle.

[0040] Gears 24 are symmetrically connected to the left and right bearings on the top of the mounting plate 1. The middle of the gears 24 is connected to the switch valve 26 via a sprocket mechanism. The switch valve 26 is installed on the outlet at the bottom of the storage box 27. The outlet of the storage box 27 is connected to the lubrication channel 28 via a connecting pipe. The lubrication channel 28 is located on the inner wall of the moving block 9. The upper outer side of the vertical rod 20 is connected to the equidistant gear plate 23 via the fourth ratchet assembly 22. The equidistant gear plate 23 has teeth evenly distributed on its outer side. Gears 24 are connected to both the left and right sides of the equidistant gear plate 23. A torsion spring 25 is installed between the bottom of the gear 24 and the top of the mounting plate 1. The gears 24 form a reciprocating rotation structure through the equidistant gear plate 23 and the torsion spring 25. The gears 24 drive the switch valve 26 via the sprocket mechanism to form a switching structure. Figure 1 and Figure 5-8 As shown, during long-term operation, the mechanical wear between components is significant, necessitating lubrication. At this time, the second motor 19 drives the vertical rod 20 to reverse, the third ratchet assembly 21 is disengaged, and the vertical rod 20 drives the equidistant gear 23 to rotate via the fourth ratchet assembly 22. The equidistant gear 23 intermittently meshes with the outer gear 24, causing the gear 24 to rotate. The rotation of the gear 24 reverses the torsion spring 25. When the equidistant gear 23 and gear 24 are disengaged, the torsion spring 25 drives the gear 24 to rotate back, causing the gear 24 to reciprocate. The rotation of the gear 24 then drives the switch valve 26 to open and close via the sprocket mechanism, evenly delivering the lubricating oil from the storage tank 27 to the lubrication channel 28 inside the moving block 9, thereby lubricating the moving block 9 and the first reciprocating screw 7 and reducing mechanical wear.

[0041] Working principle: When using this automated mechanical gripping device for machining and manufacturing, such as Figure 1-8As shown, firstly, during gripping, the first motor 4 on the mounting plate 1 is started, which drives the crossbar 5 to rotate. The crossbar 5 drives the first reciprocating screw 7 to rotate in the transverse groove 8 through the first ratchet assembly 6. After the first reciprocating screw 7 rotates, it drives the moving block 9 to move relative to it. The movement of the moving block 9 will drive the gripping part 10 to move synchronously, thereby adjusting the gripping width. After the first motor 4 drives the crossbar 5 to reverse, the first ratchet assembly 6 is in a disengaged state, and the crossbar 5 will drive the rotating rod 11 to rotate through the sprocket mechanism. After the rotating rod 11 rotates, it drives the telescopic rod 13 to rotate through the second ratchet assembly 12. The telescopic rod 13 drives the second reciprocating screw 14 to rotate through the bevel tooth connector. The second reciprocating screw 14 drives the gripping part 10 to move vertically, and the limiting post 15 can maintain the stability of the gripping part 10 when it moves. After the gripping part 10 moves, the gripping height can be adjusted, so as to adapt to workpieces of different sizes.

[0042] When adjusting the angle, the second motor 19 is started, which drives the vertical rod 20 to rotate. After the vertical rod 20 rotates, it drives the mounting plate 1 to rotate through the third ratchet assembly 21, thereby adjusting to a suitable gripping angle. During lubrication, the second motor 19 drives the vertical rod 20 to reverse, and the third ratchet assembly 21 is in a disengaged state. The vertical rod 20 drives the equidistant toothed disc 23 to rotate through the fourth ratchet assembly 22. After the equidistant toothed disc 23 rotates, it intermittently meshes with the gear 24, thereby driving the gear 24 to rotate. After the gear 24 rotates, it reverses the torsion spring 25. When the equidistant toothed disc 23 and the gear 24 are not meshed, the torsion spring 25 drives the gear 24 to rotate back, thereby causing the gear 24 to reciprocate. After the gear 24 rotates, it drives the switch valve 26 to open and close through the sprocket mechanism, thereby evenly delivering the lubricating oil in the storage box 27 to the lubrication channel 28 inside the moving block 9, thereby lubricating the moving block 9 and the first reciprocating screw 7, reducing mechanical wear, and thus completing a series of tasks.
