Description

Technical Field

[0001] This application relates to the field of clamping and conveying equipment, and in particular to a clamping and conveying device for processing. Background Technology

[0002] In the field of machining, clamping devices are crucial. With the development of manufacturing, the requirements for machining accuracy and efficiency are increasing, and the performance of clamping devices affects machining quality and speed. A good clamping device can ensure stable clamping and transport of workpieces, which is of great significance to a company's production efficiency and competitiveness.

[0003] In traditional machining, the conventional method for clamping and moving workpieces involves using ordinary fixed fixtures. The workpiece is placed on the machining table and held in place by the fixture. These fixtures are suitable for workpieces with regular shapes and fixed dimensions. Then, a single-track clamping mechanism is used to move the workpiece by gripping it with single-track jaws.

[0004] Minor dimensional deviations may occur in the production of workpieces of the same type, but these deviations do not affect the normal use of the workpieces. However, traditional fixed clamps cannot adaptively adjust the clamping force according to workpieces of the same type but with slight dimensional differences, resulting in unstable workpiece clamping. Single-track clamping mechanisms have a limited conveying range and cannot adjust the clamping and conveying range according to different types of workpiece sizes, exhibiting low adaptability. Utility Model Content

[0005] To address the issues of traditional fixed clamps being unable to adaptively adjust clamping force based on minute dimensional deviations of the same type of workpiece, resulting in unstable clamping, and single-track clamping mechanisms being unable to adjust the clamping range according to the size of different workpieces, this application provides a clamping and conveying device for machining.

[0006] The material clamping and conveying device for processing provided in this application adopts the following technical solution: A material clamping and conveying device for processing includes a processing table. Two clamping rails are arranged parallel above the processing table. A first drive mechanism is provided on both sides of the clamping rails to drive the two clamping rails to move in center or out of center. An elastic clamping assembly for clamping workpieces is provided on each adjacent side of the two clamping rails. Lifting components for driving the first drive mechanism to rise and fall are provided on both sides of the processing table. A second drive mechanism for driving the elastic clamping assembly to move with the workpiece is also provided on one side of the processing table.

[0007] By adopting the above technical solution, the first drive mechanism moves the two clamping tracks to center or decenter, allowing adjustment of the clamping range according to different workpiece sizes; the elastic clamping component can adaptively adjust the clamping force to stably clamp workpieces with slight dimensional deviations; the lifting component can drive the first drive mechanism to raise and lower, realizing the raising and lowering of the two clamping tracks; after the workpiece clamping and lifting is completed, the second drive mechanism is activated to drive the elastic clamping component to move the workpiece, realizing the transport of the workpiece. This solution improves the adaptability and flexibility of the clamping device and ensures the stability of workpiece processing.

[0008] Optionally, the first drive mechanism includes a first servo motor, a bidirectional lead screw fixed to the output end of the first servo motor, and two symmetrically threaded connecting blocks connected to the bidirectional lead screw. The first servo motor is arranged perpendicular to the length direction of the processing table. The bidirectional lead screw is provided with a mounting shell, and one end of the bidirectional lead screw passes through and rotates on the mounting shell. The tops of the two connecting blocks are respectively fixed to two clamping rails, and the bottoms of the two connecting blocks slide inside the mounting shell.

[0009] By adopting the above technical solution, the first servo motor drives the bidirectional lead screw to rotate, which in turn drives the two connecting blocks to move symmetrically on the bidirectional lead screw, thereby realizing the centering or decentering movement of the two clamping tracks. The clamping range can be adjusted according to the size of the workpiece.

[0010] Optionally, the elastic clamping assembly includes a connecting plate disposed on the clamping track and elastic clamping members fixed on the connecting plate near the workpiece side. Multiple sets of elastic clamping members are provided, and the multiple sets of elastic clamping members are fixed on the connecting plate along the length direction of the connecting plate and at uniform intervals.

[0011] By adopting the above technical solution, multiple sets of elastic clamping components are evenly spaced along the length of the connecting plate, which can simultaneously clamp multiple workpieces placed on the processing table, effectively improving the working efficiency of the clamping device and enabling the clamping operation of multiple workpieces to be completed at one time.

[0012] Optionally, the elastic clamping member includes a first guide rail fixed to the connecting plate, a first slider sliding on the first guide rail, a gripper fixed to the first slider, a snap-fit ​​groove formed on the side of the gripper near the workpiece, and two springs disposed on the side of the connecting plate away from the workpiece. A mounting plate is fixed to the side of the first guide rail away from the workpiece, and the bottom of the mounting plate is fixed to the connecting plate. The snap-fit ​​groove is used to snap the edge of the workpiece to achieve clamping and fixing of the workpiece. The two springs are respectively located on both sides of the end of the first guide rail away from the workpiece, and the two ends of the springs are respectively fixed to the slider and the mounting plate.

[0013] By adopting the above technical solution, the gripper can slide along the first guide rail with the cooperation of the first guide rail and the first slider. The locking groove can lock onto the edge of the workpiece to achieve clamping and fixing of the workpiece. The spring enables the gripper to adaptively adjust the clamping force according to the slight difference in workpiece size, thereby stabilizing the clamping of the workpiece and avoiding the problem of unstable clamping due to slight deviations in workpiece size.

[0014] Optionally, the lifting component is a double-headed cylinder, and the piston rod of the double-headed cylinder is fixed to the bottom of the mounting shell to drive the first driving mechanism to move up and down to realize the lifting of the two clamping rails.

[0015] By adopting the above technical solution, the piston rod of the double-headed cylinder is fixed at the bottom of the mounting shell, which can drive the first drive mechanism to move up and down, realize the lifting and lowering of the two clamping rails, and facilitate the subsequent transportation of the workpiece using the second drive mechanism.

[0016] Optionally, the second drive mechanism includes a second servo motor, a lead screw fixed to the output end of the second servo motor, a receiving plate fixed to the lead screw nut, and two sets of limiting mechanisms symmetrically arranged on the receiving plate. The second servo motor is arranged parallel to the length direction of the processing table. A baffle is provided at the end of the lead screw away from the second servo motor. The lead screw rotates on the baffle. The limiting mechanism cooperates with the centering or decentering movement and lifting movement of the two clamping rails. The two connecting plates are respectively connected to the two sets of limiting mechanisms, so that the second drive mechanism drives the two sets of elastic clamping components to move to realize the transportation of the workpiece.

[0017] By adopting the above technical solution, the second servo motor drives the lead screw to rotate, causing the receiving plate to move, which in turn drives the elastic clamping assembly to move the workpiece along the clamping track. The limiting mechanism can cooperate with the centering or decentering movement and lifting movement of the two clamping tracks, enabling the second drive mechanism to adapt to changes in the movement of the clamping tracks without affecting the transportation of the workpiece.

[0018] Optionally, the limiting mechanism includes a second guide rail fixed to the receiving plate, a second slider sliding on the second guide rail, a connecting rod fixed to the second slider, a stop post fixed to the connecting rod, and a sleeve sliding on the connecting rod. The connecting plate is sleeved on the connecting rod, and the connecting plate is located between the sleeve and the stop post.

[0019] By adopting the above technical solution, the second guide rail and the second slider can be configured to coordinate the centering or decentering movements of the two clamping rails. The connecting plate is sleeved on the connecting rod and located between the sleeve and the stop post, which can ensure the stability and accuracy of the lifting of the elastic clamping assembly during the lifting process of the clamping rails.

[0020] Optionally, a support platform is provided on both sides of the processing table. The support platform is used to fix the double-headed cylinder, and a mounting block for connecting the baffle and the second servo motor is fixed on the support platform near the second drive mechanism.

[0021] By adopting the above technical solution, the support platform can fix the double-headed cylinder, ensuring stable operation of the double-headed cylinder to drive the first drive mechanism to move up and down, thereby raising and lowering the two clamping tracks. The mounting block on the support platform near the second drive mechanism fixes the baffle and the second servo motor, ensuring stable operation of the second drive mechanism, and thus ensuring that the elastic clamping assembly moves stably with the workpiece.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The first drive mechanism drives the two clamping tracks to move in the center or out of the center, which can adjust the clamping range according to different types of workpiece sizes, thus solving the problem that the single track clamping mechanism cannot adjust the clamping and conveying range according to different types of workpiece sizes; 2. The elastic clamping component in the elastic clamping assembly can adaptively adjust the clamping force according to workpieces of the same type but with slight differences, so as to achieve stable clamping of the workpiece. This improves the problem that traditional fixed clamps cannot adjust the clamping force according to workpieces with slight differences in size, resulting in unstable clamping. 3. The lifting component drives the first drive mechanism to rise and fall, and in conjunction with the second drive mechanism, drives the elastic clamping assembly to move the workpiece, which can realize the conveying of the workpiece at different heights and positions, and improve the flexibility of the clamping device.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a clamping and conveying device for processing.

[0028] Reference Figure 1 and Figure 2 A material handling and conveying device for machining includes a machining table 1, two clamping rails 2, two sets of first drive mechanisms 3, two sets of elastic clamping assemblies 4, two sets of lifting components 5, and a second drive mechanism 6. The workpiece is placed on the machining table 1 along its length.

[0029] Reference Figure 1 Two clamping rails 2 are arranged parallel to each other above the machining table 1, with each clamping rail 2 located on either side of the workpiece. Two sets of first drive mechanisms 3 are respectively arranged on both sides of the clamping rails 2 along the length of the machining table 1, used to drive the two clamping rails 2 to move in a centered or decentered manner. Two sets of elastic clamping components 4 are respectively arranged on adjacent sides of the two clamping rails 2, so that when the two clamping rails 2 move in a centered manner through the first drive mechanism 3, the two elastic clamping components 4 are driven to move in a centered manner simultaneously, thereby realizing the elastic clamping and fixing of the workpiece.

[0030] Reference Figure 1 Two lifting components 5 are respectively arranged on both sides of the processing table 1 along its length. They are used to drive the first drive mechanism 3 to rise and fall, thereby driving the clamping track 2, which elastically clamps the workpiece, to rise and fall, facilitating subsequent workpiece transportation. The second drive mechanism 6 is located on one side of the processing table 1 and is used to drive the elastic clamping assembly 4 to move with the workpiece, realizing workpiece transportation. The lifting components 5 drive the first drive mechanism 3, the clamping track 2, and the elastic clamping assembly 4 to rise and fall, and the second drive mechanism 6 drives the elastic clamping assembly 4 to move with the workpiece, enabling the workpiece to be transported at different heights and positions, improving the flexibility of the clamping device.

[0031] Traditional single feeding tracks have fixed dimensions, requiring manual replacement when feeding workpieces of different sizes, which is cumbersome, time-consuming, and labor-intensive. In contrast, the first drive mechanism 3 enables the two clamping tracks 2 to move centered or offset, allowing adjustment of the clamping range according to different workpiece sizes, thus improving the adaptability of the clamping device. Fixed clamps can be unstable when clamping workpieces with slight differences, causing them to fall during transport and severely impacting transport efficiency. Compared to traditional fixed clamps, the elastic clamping component 4 can adaptively adjust to minor dimensional differences in the same type of workpiece due to processing technology, achieving stable clamping.

[0032] Reference Figure 3 The first drive mechanism 3 includes a first servo motor 31, a bidirectional lead screw 32, two connecting blocks 33, and a mounting housing 34. The first servo motor 31 is the power source for the entire first drive mechanism 3, and the thread direction of the bidirectional lead screw 32 is symmetrically arranged about its middle portion. The first servo motor 31 and the mounting housing 34 are arranged along the same straight line, which is perpendicular to the length direction of the processing table 1. One end of the bidirectional lead screw 32 is fixed to the output end of the first servo motor 31, and the other end of the bidirectional lead screw 32 passes through the mounting housing 34 and is rotatably connected to the inner wall of the mounting housing 34. The two connecting blocks 33 are symmetrically threaded onto the bidirectional lead screw 32, and the tops of the two connecting blocks 33 are respectively fixed to the two clamping rails 2. In addition, the bottoms of the two connecting blocks 33 can slide within the mounting housing 34 to ensure the smooth movement of the connecting blocks 33 and avoid shaking or displacement.

[0033] Reference Figure 1 and Figure 3 When the first servo motor 31 is started to rotate forward, the two connecting blocks 33 are centered due to the threaded connection between the bidirectional lead screw 32 and the two connecting blocks 33. When the two connecting blocks 33 move in center, they can drive the two clamping rails 2 to move in center, and drive the two elastic clamping components 4 to move in center to achieve elastic clamping of the workpiece.

[0034] Reference Figure 1 and Figure 3 When the first servo motor 31 is started to reverse, the two connecting blocks 33 are moved away from the center due to the threaded connection between the bidirectional lead screw 32 and the two connecting blocks 33. When the two connecting blocks 33 move away from the center, they can drive the two clamping tracks 2 to move away from the center, thereby releasing the elastic clamping effect of the two elastic clamping components 4 on the workpiece.

[0035] Reference Figure 3In this embodiment, the lifting component 5 is a double-headed cylinder with two piston rods fixed to the bottom of the mounting housing 34. When the double-headed cylinder is activated, the extension and retraction of the piston rods drives the first drive mechanism 3 to move up and down, thereby realizing the lifting and lowering of the two clamping rails 2.

[0036] Reference Figure 4 The elastic clamping assembly 4 includes a connecting plate 41 and elastic clamping members 42. The connecting plate 41 serves as the mounting base for the elastic clamping members 42, and is positioned on the clamping track 2 to provide support for them. Multiple sets of elastic clamping members 42 are fixed to the connecting plate 41 near the workpiece, with each set evenly spaced along the length of the connecting plate 41. This arrangement allows for the simultaneous clamping of multiple workpieces placed on the processing table 1, effectively improving the working efficiency of the clamping device and enabling the processing of multiple workpieces at once.

[0037] Reference Figure 4 The elastic clamping component 42 includes a first guide rail 421, a first slider 422, a gripper 423, a locking groove 424, two springs 425, and a mounting plate 426. The first guide rail 421 is fixed to the connecting plate 41, providing a track for the sliding of the first slider 422. The first slider 422 slides freely on the first guide rail 421. The gripper 423 is fixed to the first slider 422, and moves accordingly when the first slider 422 moves. The locking groove 424 is located on the side of the gripper 423 closest to the workpiece, used to engage the edge of the workpiece for clamping and fixing. The mounting plate 426 is located on the side of the first guide rail 421 furthest from the workpiece, and is fixed to both the first guide rail 421 and the connecting plate 41. The two springs 425 are located on opposite sides of the first guide rail 421 furthest from the workpiece, and their ends are fixed to the slider and the mounting plate 426, respectively.

[0038] Reference Figure 1 and Figure 4 When the first drive mechanism 3 drives the two clamping tracks 2 to move in a centered position, it will in turn drive the two elastic clamping components 4, which are respectively set on the two clamping tracks 2, to move in a centered position. When the gripper 423 contacts the workpiece, due to the slight difference in the size of the workpiece, the gripper 423 will drive the first slider 422 to slide on the first guide rail 421. At this time, the spring 425 will be compressed or stretched, thereby generating an elastic force. This elastic force can adaptively adjust the clamping force to ensure stable clamping of the workpiece.

[0039] Reference Figure 5The second drive mechanism 6 includes a second servo motor 61, a lead screw 62, a receiving plate 63, two sets of limiting mechanisms 64, and a baffle 65. The second servo motor 61 is the power source for the second drive mechanism 6, and its use allows for precise control of speed and direction. The lead screw 62 is fixed to the output end of the second servo motor 61, and the receiving plate 63 is fixed to the nut of the lead screw 62. The length of the lead screw 62 can be determined according to the preset workpiece transport distance. The baffle 65 is located at the end of the lead screw 62 furthest from the second servo motor 61, and the lead screw 62 rotates on the baffle 65, which provides support and limits the movement of the lead screw 62. The two sets of limiting mechanisms 64 are symmetrically arranged on the receiving plate 63 and are used to coordinate with the centering or decentering movement and lifting movement of the two clamping rails 2.

[0040] Reference Figure 1 and Figure 5 When the second servo motor 61 starts, it drives the lead screw 62 to rotate. As the lead screw 62 rotates, the nut of the lead screw 62 moves linearly along the lead screw 62, thereby driving the receiving plate 63 to move. In addition, the two connecting plates 41 are respectively connected to two sets of limiting mechanisms 64, so that the second drive mechanism 6 can move the two sets of elastic clamping components 4 to realize the conveying of the workpiece.

[0041] Reference Figure 5 The limiting mechanism 64 includes a second guide rail 641, a second slider 642, a connecting rod 643, a stop post 644, and a sleeve 645. The second guide rail 641 is fixed to the receiving plate 63, providing a track for the sliding of the second slider 642. The connecting rod 643 is fixed to the second slider 642, and moves accordingly when the second slider 642 moves. The stop post 644 is fixed to the connecting rod 643, serving to block and limit movement. The sleeve 645 slides on the connecting rod 643, and a connecting plate 41 is sleeved on the connecting rod 643, positioned between the sleeve 645 and the stop post 644. This arrangement ensures that the movement range of the connecting plate 41 on the connecting rod 643 is limited, while also allowing the limiting mechanism 64 to coordinate with the movement of the clamping track 2.

[0042] Reference Figure 1 Support platforms 7 are provided on both sides of the processing table 1. The support platforms 7 are used to fix the double-headed cylinder and ensure its stability. In addition, a mounting block 8 for connecting the baffle 65 and the second servo motor 61 is fixed on the support platform 7 near the second drive mechanism 6. The mounting block 8 plays a connecting and fixing role to ensure the normal operation of the second drive mechanism 6.

[0043] Initially, the workpiece is arranged along the length of the processing table 1, with two clamping rails 2 positioned on either side of the workpiece. The first servo motor 31 is started to rotate forward, causing the first drive mechanism 3 to move the two clamping rails 2 in a centered position, achieving elastic clamping and fixing of the workpiece. Then, the piston rod of the double-headed cylinder is extended to lift the two clamping rails 2, thereby lifting the clamped workpiece and placing it above the processing table 1. Finally, the second servo motor 61 is started to rotate forward, causing the second drive mechanism 6 to move the elastic clamping assembly 4 to transport the workpiece.

[0044] When the second drive mechanism 6 transports the workpiece to the preset position, the first servo motor 31 is activated to reverse, causing the first drive mechanism 3 to move away from the center along with the two clamping tracks 2, releasing the workpiece from its clamping position. After the workpiece is released, the piston rod of the double-headed cylinder is retracted, moving the two clamping tracks 2 back to their original height. Then, the second servo motor 61 is activated to reverse, causing the second drive mechanism 6 to move the two tracks back to their original position.

[0045] The implementation principle of the clamping and conveying device for machining according to an embodiment of this application is as follows: The first driving mechanism 3 adjusts the distance between the two clamping tracks 2, accommodating workpieces of different sizes and expanding the clamping and conveying range. The elastic clamping assembly 4 utilizes the elastic force of the spring 425 to adaptively adjust the clamping force according to slight differences in workpiece size, ensuring stable clamping of the workpiece. The lifting component 5 enables the clamping tracks 2 to operate at different heights, increasing the flexibility of the device. The second driving mechanism 6 and the limiting mechanism 64 realize the conveying of the workpiece and ensure the stability of the conveying process. Compared with traditional fixed fixtures and single-track clamping mechanisms, this device improves adaptability and stability, effectively solves the problems existing in traditional devices, and improves the efficiency and quality of machining.
