Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to a dual-motor driven automated stamping flipping mechanism. Background Technology

[0002] In the field of stamping, especially in scenarios where stamping is required on both sides or at multiple angles of a workpiece, a dual-motor driven automated stamping tilting mechanism is the core equipment for achieving workpiece posture adjustment and continuous processing. Existing dual-motor driven stamping tilting mechanisms typically consist of a conveyor assembly, a tilting drive assembly, a clamping assembly, and a stamping execution assembly. Their working logic is generally as follows: the workpiece is conveyed to a designated station via a conveyor belt; after the workpiece is fixed by the clamping assembly, the tilting drive assembly rotates the workpiece to the target angle; the stamping assembly then completes the stamping operation; and finally, the processed workpiece is conveyed to the next process via a conveyor belt.

[0003] However, in practical applications, the dual-motor driven automatic stamping turning mechanism in the above technical solution still has the following defects: traditional stamping clamping generally lacks an overpressure protection mechanism. When the clamping force exceeds the set value, it is easy to damage the hydraulic components. In addition, the lubrication of the mechanical rotating parts requires regular manual maintenance, which increases the maintenance cost of the equipment. Therefore, it is necessary to provide a dual-motor driven automatic stamping turning mechanism to solve the above problems. Summary of the Invention

[0015] As a preferred embodiment of the present invention, the clamping unit includes: a piston groove, formed inside the side plate, with a first piston member slidably connected inside the piston groove; a push rod, one end of which is fixed to the side of the first piston member, and the other end of which is fixed to a clamp; a piston cylinder, connected to the side of the side plate, and communicating with each set of piston grooves through a main channel; a second piston member, slidably connected inside the piston cylinder, and connected to the inner wall of the piston cylinder through a first compression spring; and a slide rod, slidably connected to the end of the piston cylinder, with the end of which is connected to the second piston member.

[0016] As a preferred embodiment of the present invention, a roller is installed at the end of the slide rod away from the piston cylinder, and a cam is installed on the surface of the inner ratchet, with the roller slidably connected to the surface of the cam.

[0017] As a preferred embodiment of the present invention, the adjusting unit includes: an adjusting groove formed on the side of the piston cylinder, the end of the adjusting groove being connected to a secondary flow channel, the end of the secondary flow channel extending to the connection between the side plate and the inner ratchet; a third piston member slidably connected to the piston cylinder inside away from the second piston member; and an adjusting rod threadedly connected to the end of the piston cylinder, the inner end of the adjusting rod being connected to the surface of the third piston member via a second compression spring.

[0018] As a preferred embodiment of the present invention, the stamping unit includes: a sliding member slidably connected to the lower top of the machine tool; a linear motor mounted on the upper end face of the machine tool, wherein the side of the sliding member is rigidly connected to the moving end of the linear motor, and the linear motor is used to drive the sliding member to perform reciprocating linear motion along the horizontal axis of the machine tool; a hydraulic cylinder, wherein the cylinder body of the hydraulic cylinder is fixedly connected to the bottom of the sliding member; and a stamping head, wherein the stamping head is detachably connected to the output end of the hydraulic cylinder.

[0019] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0020] 1. This invention realizes fully automated integrated operation of workpiece transfer, flipping, clamping, stamping, and unloading. Through the cyclic rotation of four sets of carriers and the first and second conveyor belts with height differences, the continuous flow processing of workpieces is completed without manual intervention in loading, unloading, and flipping operations, which improves the automation level and production efficiency of stamping processing. The internal ratchet and pawl cooperation structure can accurately position the rotation angle of the drive shaft, ensuring that the carrier can be stably stopped at any angle to meet the multi-angle stamping requirements of workpieces.

[0021] 2. The automatic clamping and loosening of the fixture is achieved through the mechanical cooperation of the roller and cam and hydraulic transmission; and the clamping force of the fixture can be flexibly adjusted with the help of the adjustment unit to adapt to the clamping requirements of workpieces of different materials and thicknesses, avoiding the problems of deformation of soft thin-walled workpieces and loosening of hard heavy workpieces.

[0022] 3. It has overpressure unloading and automatic lubrication functions. When the hydraulic pressure in the piston cylinder exceeds the set value, the third piston slides to open the unloading channel. The hydraulic oil flows through the secondary channel to lubricate the rotating parts of the side plate and the inner ratchet. This not only avoids damage to the workpiece caused by the clamp due to overpressure, but also reduces the wear of mechanical parts and extends the service life of the equipment.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0032] See Figures 1-5 A dual-motor driven automated stamping flipping mechanism, comprising:

[0033] Machine tool 1, wherein a first conveyor belt 11 and a second conveyor belt 12 are respectively installed at both ends of the machine tool 1;

[0034] Rotary unit 2 is rotatably connected to machine tool 1 and is used to drive the workpiece to rotate.

[0035] The clamping unit 3 is slidably connected inside the rotating unit 2 and is used to cooperate with the rotating unit 2 to realize the automatic clamping and loosening of the workpiece;

[0036] The stamping unit 5 is slidably connected to the machine tool 1 and is used to stamp the workpiece on the rotating unit 2.

[0037] In one embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the rotating unit 2 includes: a driving component 21, which is installed on the side of the machine tool 1; a driving shaft 22, which is rotatably connected to the machine tool 1 and whose end is connected to the output end of the driving component 21; and a carrying rack 24, which is installed on the surface of the driving shaft 22. The carrying rack 24 is provided in four sets, and side plates 25 are installed at both ends of the four sets of carrying racks 24.

[0038] Furthermore, the horizontal height of the first conveyor belt 11 is higher than that of the second conveyor belt 12; the carrier 24 is provided with a stamping hole 241, and the surface of the carrier 24 is provided with anti-slip texture 242; an inner ratchet 26 is fixed on the inner wall of the machine tool 1, a rotating disk 23 is fixed on the surface of the drive shaft 22, a pawl 27 is rotatably connected to the rotating disk 23, the end of the pawl 27 is engaged in the ratchet groove of the inner ratchet 26, and a spring piece 28 for limiting the pawl 27 is fixed on the side of the rotating disk 23.

[0039] By adopting the above technical solution, automated transfer, flipping, clamping, and integrated stamping operations of the workpiece during the stamping process are achieved, effectively improving the automation level and production efficiency of stamping processing. Specifically, when processing the workpiece, it is first placed on the first conveyor belt 11, and the first conveyor belt 11 is started. The workpiece is transported to the corresponding carrier 24 via the first conveyor belt 11. The anti-slip texture 242 can increase the friction between the workpiece and the carrier 24, preventing the workpiece from shifting during flipping and stamping, and ensuring processing accuracy.

[0040] The drive unit 21 is activated, causing the drive shaft 22 to rotate the workpiece on its surface via the carrier 24. The side plates 25 on both sides of the carrier 24 can limit the workpiece, improving the stability of the workpiece during processing. Simultaneously, as the drive shaft 22 rotates, it drives the pawl 27 to rotate synchronously via the rotating disk 23, allowing the pawl 27 to slide inside the inner ratchet 26. The spring plate 28 continuously applies elastic pressure to the pawl 27, ensuring that the pawl 27 and the ratchet groove of the inner ratchet 26 remain stably engaged, improving the reliability of the positioning mechanism. The mating structure of the inner ratchet 26 and the pawl 27 allows for precise positioning of the rotation angle of the drive shaft 22, ensuring that the carrier 24 can rotate stably to any angle, allowing the stamping unit 5 to stamp the workpiece at different angles. Compared to traditional manual flipping or single-station stamping equipment, this solution not only reduces the intensity of manual operation and minimizes the impact of human factors on processing accuracy, but also enables multi-angle stamping of workpieces, making it more widely applicable.

[0041] In one embodiment of the present invention, such as Figure 5As shown, the clamping unit 3 includes: a piston groove 31, which is formed inside the side plate 25, and a first piston member 32 is slidably connected inside the piston groove 31; a push rod 33, one end of which is fixed to the side of the first piston member 32, and the other end of which is fixed to a clamp 34; a piston cylinder 36, which is connected to the side of the side plate 25 and communicates with each set of piston grooves 31 through the main channel 35; a second piston member 37, which is slidably connected inside the piston cylinder 36, and the second piston member 37 is connected to the inner wall of the piston cylinder 36 through a first compression spring 39; a slide rod 38, which is slidably connected to the end of the piston cylinder 36, and the end of which is connected to the second piston member 37. A roller 381 is installed at the end of the slide rod 38 away from the piston cylinder 36, and a cam 261 is installed on the surface of the inner ratchet 26. The roller 381 is slidably connected to the surface of the cam 261.

[0042] By adopting the above technical solution, the clamping action and the rotation action are linked and coordinated, eliminating the need for an additional independent clamping drive source. The specific working process is as follows: When the drive component 21 drives the drive shaft 22 and the carrier 24 to rotate, the clamping unit 3 on the carrier 24 will rotate around its axis along with the drive shaft 22. At this time, the roller 381 at the end of the slide bar 38 always slides against the inner ratchet 26 fixed to the inner wall of the machine tool 1. Figure 4 As shown, when the carrier 24 rotates to the workpiece receiving position (i.e., the docking position with the first conveyor belt 11), the roller 381 gradually slides to the distal end of the cam 261, causing the roller 381 to slide onto the cam 261 on the surface of the inner ratchet 26. Under the action of the cam 261 and the roller 381, the slide rod 38 pushes the second piston 37 to slide towards the main channel 35 inside the piston cylinder 36. At the same time, the second piston 37 stretches the first compression spring 39. Under the squeezing action of the second piston 37, the hydraulic oil in the piston cylinder 36 is diverted through the main channel 35 to each set of piston grooves 31. The hydraulic oil pushes the first piston 32 to slide in the piston groove 31, and then drives the clamp 34 to move towards the workpiece through the push rod 33, so that the clamp 34 clamps the workpiece, making it easier for the stamping unit 5 to stamp the workpiece.

[0043] After the workpiece completes the stamping process at the preset angle, the output end of the drive unit 21 continues to drive the drive shaft 22 to rotate, and the carrier 24 then drives the workpiece to rotate to the unloading station, that is, to rotate above the second conveyor belt 12. The height difference design between the first conveyor belt 11 and the second conveyor belt 12 (the height difference is 30-80mm), together with the cyclic rotation of the four sets of carriers 24, realizes the smooth flow of workpieces.

[0044] The carrier 24 rotates the workpiece to the side of the second conveyor belt 12. During this process, the roller 381 at the end of the slide bar 38 gradually slides from the distal end to the proximal end of the cam 261, and the tension of the first compression spring 39 is gradually released. Under the elastic force of the first compression spring 39, the second piston 37 slides away from the main flow channel 35, and a negative pressure is formed inside the piston cylinder 36. At this time, the hydraulic oil in each set of piston grooves 31 flows back to the piston cylinder 36 through the main flow channel 35 under the action of negative pressure. The first piston 32 slides in the opposite direction along the piston groove 31 under the drive of the hydraulic oil return, and pulls the clamp 34 away from the workpiece through the push rod 33, realizing the automatic release of the workpiece.

[0045] When the carrier 24 rotates to the unloading station where it connects with the second conveyor belt 12, the workpiece slides onto the second conveyor belt 12 under its own weight and the rotational inertia of the carrier. The second conveyor belt 12 then transports the processed workpiece to the subsequent process. At the same time, since there are four sets of carriers 24, the remaining empty carriers 24 will continue to perform a cycle of clamping, rotating, and releasing the workpiece, realizing continuous and automated processing of the workpiece.

[0046] The clamping surface of the fixture 34 is connected to a flexible anti-slip pad, which increases the friction with the workpiece and prevents indentations or scratches on the workpiece surface during clamping. The machine tool 1 is also equipped with a position sensor, which detects the rotational position of the carrier 24 in real time and transmits the position signal to the equipment control system. The control system precisely controls the start / stop of the drive component 21 and the working state of the stamping unit 5 based on the position sensor signal, achieving precise coordination of the actions of each mechanism.

[0047] In one embodiment of the present invention, such as Figure 5 As shown, the adjustment unit 4 includes: an adjustment groove 41, which is opened on the side of the piston cylinder 36, and the end of the adjustment groove 41 is connected to a secondary flow channel 42, the end of the secondary flow channel 42 extending to the connection between the side plate 25 and the inner ratchet 26; a third piston member 43, which is slidably connected to the inside of the piston cylinder 36 away from the second piston member 37; and an adjustment rod 44, which is threadedly connected to the end of the piston cylinder 36, and the inner end of the adjustment rod 44 is connected to the surface of the third piston member 43 through a second compression spring 45.

[0048] By adopting the above technical solution, the clamping force of the fixture 34 can be flexibly adjusted to meet the clamping requirements of workpieces of different materials and thicknesses, effectively improving the adaptability of the equipment. Specifically, when it is necessary to process workpieces of different specifications, the operator can rotate the adjusting rod 44 to move the adjusting rod 44 along the axis of the piston cylinder 36. Then, the end of the adjusting rod 44 pushes or pulls the third piston 43 to slide inside the piston cylinder 36 through the second compression spring 45.

[0049] When the adjusting rod 44 is rotated clockwise, it moves into the piston cylinder 36, pushing the third piston 43 to stretch the second compression spring 45 and move towards the second piston 37. At this time, the third piston 43 will squeeze the hydraulic oil chamber in the piston cylinder 36, increasing the pressure in the chamber. This will generate greater pressure on the first piston 32, which in turn will drive the clamp 34 to generate greater clamping force through the push rod 33, so as to meet the stable clamping requirements of workpieces with high hardness and heavy weight, and prevent such workpieces from loosening or shifting during the stamping process.

[0050] When the adjusting rod 44 is rotated in the opposite direction, the adjusting rod 44 retracts outward from the piston cylinder 36. The adjusting rod 44 drives the third piston 43 to move away from the second piston 37 through the second compression spring 45. The volume of the hydraulic oil chamber in the piston cylinder 36 increases, the pressure in the chamber decreases, and the clamping force applied to the workpiece by the corresponding clamp 34 decreases. This is suitable for workpieces with softer materials and thinner thickness, and prevents workpiece deformation due to excessive clamping force.

[0051] When clamping the workpiece, the second piston 37 slides into the piston cylinder 36 and pressurizes the hydraulic oil inside the piston cylinder 36. When the pressure inside the piston cylinder 36 reaches the set value, the third piston 43 slides to the other end of the piston cylinder 36 under the pressure of the hydraulic oil and compresses the second compression spring 45. When the third piston 43 slides, the port of the adjusting groove 41 is exposed, so the hydraulic oil inside the piston cylinder 36 flows out from the secondary flow channel 42 through the adjusting groove 41 and finally flows to the connection between the side plate 25 and the inner ratchet 26, and the meshing part between the inner ratchet 26 and the pawl 27, providing lubrication for the relative rotation of the two, reducing mechanical wear, and realizing pressure unloading of the hydraulic system, avoiding damage to hydraulic components due to excessive pressure, and ensuring the safety and stability of the clamping unit 3. Once the hydraulic oil pressure drops below the set threshold, the elastic restoring force of the second spring 45 will push the third piston 43 to slide in the opposite direction, re-seal the port of the adjusting groove 41, restore the hydraulic system to normal pressure, and ensure the clamping force of the clamp 34 is stable.

[0052] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the stamping unit 5 includes:

[0053] Sliding member 51 is slidably connected to the lower top of machine tool 1;

[0054] A linear motor 52 is mounted on the upper end face of the machine tool 1. The side of the sliding member 51 is rigidly connected to the moving end of the linear motor 52. The linear motor 52 is used to drive the sliding member 51 to perform reciprocating linear motion along the horizontal axis of the machine tool 1.

[0055] Hydraulic cylinder 53, the cylinder body of which is fixedly connected to the bottom of sliding member 51;

[0056] A stamping head 54 is detachably connected to the output end of a hydraulic cylinder 53.

[0057] By adopting the above technical solution, high-precision and high-flexibility control of the stamping action is achieved, meeting the stamping processing requirements of different workpieces at different positions. The specific working process is as follows: When the position sensor detects that the carrier 24 has driven the workpiece to rotate to the preset stamping position and completed the clamping action, it will transmit the signal to the equipment control system. The control system will then start the linear motor 52. The moving end of the linear motor 52 drives the sliding part 51 to move along the horizontal axis of the machine tool 1, which in turn drives the hydraulic cylinder 53 and the stamping head 54 to move horizontally, realizing precise adjustment of the stamping position and adapting to the processing requirements of workpieces of different sizes or different stamping points of the same workpiece. After the stamping head 54 moves to the target stamping position, the control system controls the hydraulic cylinder 53 to start. The output end of the hydraulic cylinder 53 drives the stamping head 54 to move downward in a straight line, and the stamping head 54 performs stamping processing on the workpiece on the carrier 24. The setting of the stamping hole 241 not only provides the movement space for the stamping head 54, but also plays a certain guiding role in the downward trajectory of the stamping head 54, improving the stamping accuracy.

[0058] After stamping is completed, the output end of the hydraulic cylinder 53 drives the stamping head 54 to return to its original position. The stamping head 54 and the output end of the hydraulic cylinder 53 are detachably connected. The operator can replace the stamping head 54 with different shapes and specifications, such as round stamping head, square stamping head, and patterned stamping head, according to the stamping process requirements of the workpiece, thus expanding the applicability of this mechanism.

[0059] The working principle of this invention is as follows: The workpiece is conveyed to the carrier 24 via the first conveyor belt 11. The anti-slip texture 242 and the side plate 25 ensure the initial stable positioning of the workpiece. The start-up drive 21 drives the drive shaft 22 and the carrier 24 to rotate. The inner ratchet 26 and the pawl 27 cooperate to achieve precise angular positioning of the carrier 24. During the rotation, the clamping unit 3 rotates synchronously with the carrier 24. The roller 381 at the end of the slide bar 38 slides along the surface of the inner ratchet 26. When it reaches the stamping station, the roller 381 is in contact with the distal end of the cam 261, pushing the second piston 37 to squeeze the hydraulic oil. This causes the hydraulic oil to drive the fixture 34 to clamp the workpiece through the main channel 35. By rotating the adjusting rod 44, the pressure of the hydraulic chamber inside the piston cylinder 36 can be changed to adapt to the clamping force requirements of different workpieces. In case of overpressure, unloading can be achieved to lubricate the cam 261 and the side plate 25. After the carrier 24 rotates to the stamping station, the output end of the hydraulic cylinder 53 drives the stamping head 54 to move downward in a straight line, and the stamping head 54 performs stamping processing on the workpiece on the carrier 24. After processing, the carrier 24 rotates to the side of the second conveyor belt 12, the roller 381 slides to the proximal end of the cam 261, the first compression spring 39 resets and drives the hydraulic oil to flow back, the clamp 34 is released, and the workpiece moves to the next station via the second conveyor belt 12, realizing continuous operation of workpiece transfer, flipping, clamping, stamping and unloading.
