Description

Technical Field

[0001] This utility model relates to the field of positioning and clamping technology for aluminum substrate processing, specifically to a positioning and clamping device for aluminum substrate processing. Background Technology

[0002] Positioning and clamping devices for aluminum substrate processing are tooling equipment designed to accommodate the thinness and high thermal conductivity of aluminum substrates. They achieve rapid positioning and stable clamping of the substrate through mechanical or pneumatic structures and are widely used in processing steps such as drilling, cutting, and milling.

[0003] When using existing positioning and clamping devices for aluminum substrate processing...

[0004] (1) The lifting adjustment accuracy is low, and it relies on manual operation or simple transmission structure. It is difficult to accurately control the height of the aluminum substrate according to the processing requirements, which leads to the relative position deviation between the processing equipment and the substrate and affects the processing accuracy.

[0005] (2) The clamping mechanism is not stable enough. Most of the transmission components such as ball screws are fixed at one end. When running at high speed, radial runout is likely to occur, and the clamping force is unevenly distributed, which can easily cause the aluminum substrate to shift or the surface to scratch.

[0006] To address the above problems, this utility model provides a positioning and clamping device for aluminum substrate processing. Utility Model Content

[0007] The purpose of this invention is to provide a positioning and clamping device for aluminum substrate processing. This invention has high-precision lifting and adjustment, stable and symmetrical clamping, and safety protection functions, thereby solving the problems of low lifting accuracy, poor clamping stability, and insufficient operational safety of existing devices.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a positioning and clamping device for aluminum substrate processing, comprising an operating table and a lifting assembly. The operating table has a groove in the middle, and the lifting assembly is fixedly connected to the middle of the bottom of the groove. The lifting assembly includes a first servo motor, one end of which is fixedly connected to a first transmission rod, and one end of the first transmission rod is fixedly connected to a threaded sleeve. A threaded rod is threadedly connected to the middle of the threaded sleeve, and a lifting table is fixedly connected to the top of the threaded rod.

[0009] Furthermore, a limiting rod is fixedly connected to the inner bottom of the operating table groove, and a lifting rod is slidably connected to the middle of the limiting rod. One end of the lifting rod is connected to the lifting platform, which achieves the function of guiding and limiting the lifting platform, preventing deviation during the lifting process, and improving the lifting accuracy.

[0010] Furthermore, a fixed platform is fixedly connected to one edge of each side of the top of the operating table. A second servo motor is fixedly connected inside the fixed platform. A second transmission rod is fixedly connected to one end of the second servo motor. A limit platform is fixedly connected to one edge of each side of the top of the operating table, which achieves the function of providing a symmetrical installation reference for the second servo motor and the ball screw, and ensuring the synchronization of the transmission structures on both sides.

[0011] Furthermore, a ball screw is fixedly connected to one end of the second transmission rod, and a nut is engaged with the surface of the ball screw. One end of the ball screw is fixedly connected to the limiting platform, which achieves the positioning and support of both ends of the ball screw, reduces radial runout during high-speed rotation, and improves transmission stability and accuracy.

[0012] Furthermore, a connecting rod is fixedly connected to the surface of the nut, and a clamping plate is fixedly connected to one end of the connecting rod, thereby converting the rotational motion of the ball screw into the linear motion of the clamping plate, achieving the function of precise clamping and resetting of the aluminum substrate.

[0013] Furthermore, a soft pad is fixedly connected to one side of the clamping plate. The soft pad is made of rubber, which increases the friction of the clamping surface to prevent the substrate from sliding, while avoiding rigid contact that could cause scratches on the surface of the aluminum substrate.

[0014] Furthermore, a protective plate is fixedly connected to one side of the operating table, and an inspection window is fixedly connected to the front of the operating table. This achieves the purpose of blocking the splashing of processing debris to ensure operational safety, while also facilitating the observation of the operating status of internal components and making maintenance convenient.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The present invention provides a positioning and clamping device for aluminum substrate processing.

[0017] (1) By using the lifting group and the combination of the limit rod and the lifting rod, the automatic high-precision lifting adjustment of the lifting platform can be realized when the personnel operate the device, so as to ensure that the aluminum substrate and the processing equipment are in the best relative position and improve the processing size accuracy.

[0018] (2) By setting up a symmetrically distributed second servo motor, ball screw, limit stage and clamping plate with soft pad, the aluminum substrate can be clamped in both directions when the personnel operate the device. The clamping force is uniform and stable, which not only avoids substrate displacement but also protects its surface and improves the reliability of device operation. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To solve the problem of how to effectively position and adjust the technology, such as Figure 1-5 As shown, the following preferred technical solutions are provided:

[0027] A positioning and clamping device for aluminum substrate processing includes an operating table 1 and a lifting assembly 2. The operating table 1 has a groove in the middle, and the lifting assembly 2 is fixedly connected to the middle of the bottom of the groove. The lifting assembly 2 includes a first servo motor 201, a first transmission rod 202 is fixedly connected to one end of the first servo motor 201, a threaded sleeve 203 is fixedly connected to one end of the first transmission rod 202, a threaded rod 204 is threadedly connected to the middle of the threaded sleeve 203, and a lifting platform 7 is fixedly connected to the top of the threaded rod 204.

[0028] Specifically, when operating the device, the operator first places the aluminum substrate to be processed on the top of the lifting platform 7, and then starts the first servo motor 201 through the control system to drive all components to work together to complete the lifting and clamping actions.

[0029] Furthermore, such as Figure 3 As shown, the following preferred technical solutions are provided:

[0030] A limiting rod 3 is fixedly connected to the bottom of the groove of the operating table 1. A lifting rod 4 is slidably connected to the middle of the limiting rod 3. One end of the lifting rod 4 is connected to the lifting platform 7. The purpose of this design is to use the sliding cooperation between the limiting rod 3 and the lifting rod 4 to provide stable guidance for the lifting platform 7, avoid uneven force on the threaded rod 204 which would cause the lifting platform 7 to tilt, and ensure that the aluminum base plate always remains horizontal.

[0031] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0032] Fixed platforms 5 are fixedly connected to one edge of each side of the top of the operating platform 1. A second servo motor 6 is fixedly connected inside the fixed platform 5. A second transmission rod is fixedly connected to one end of the second servo motor 6. Limiting platforms 15 are fixedly connected to one edge of each side of the top of the operating platform 1. The purpose of this design is to make the fixed platform 5 and the limiting platform 15 form a symmetrical support structure, ensuring that the mounting axes of the second servo motor 6 and the ball screw 8 on both sides are collinear, thus providing a structural basis for synchronous clamping.

[0033] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0034] One end of the second transmission rod is fixedly connected to a ball screw 8, and a nut 9 is engaged with the surface of the ball screw 8. One end of the ball screw 8 is fixedly connected to the limiting platform 15. The purpose of this design is to fix the end of the ball screw 8 away from the motor through the limiting platform 15, forming a two-end support structure. Compared with single-end fixing, this can significantly reduce the deflection of the ball screw 8 and reduce vibration and offset during transmission.

[0035] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0036] A connecting rod 10 is fixedly connected to the surface of the nut 9, and a clamping plate 11 is fixedly connected to one end of the connecting rod 10. The purpose of this design is to transmit the linear movement of the nut 9 through the connecting rod 10, so that the clamping plate 11 can accurately fit the side of the aluminum substrate. At the same time, it is convenient to replace the clamping plate 11 of different specifications according to the size of the aluminum substrate, thereby improving the adaptability of the device.

[0037] Furthermore, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0038] A soft pad 12 is fixedly connected to one side of the clamping plate 11. The soft pad 12 is made of rubber. The purpose of this design is that the rubber soft pad 12 has a certain elasticity, which can conform to the surface contour of the aluminum substrate when clamping, increase the coefficient of friction, and buffer the impact of the clamping force on the substrate to avoid surface scratches or pressure damage.

[0039] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:

[0040] A protective plate 13 is fixedly connected to one side of the operating table 1, and an inspection window 14 is fixedly connected to the front of the operating table 1. The purpose of this design is that the protective plate 13 can prevent metal chips generated during drilling, milling and other processing from flying to the side. The inspection window 14 is made of tempered glass, which allows the operator to observe the operating status of the lifting assembly 2 and the ball screw 8 without stopping the machine, and to detect abnormalities in time.

[0041] Working principle: When the device is running, the height of the lifting assembly 2 is first adjusted according to the thickness of different aluminum substrates to adapt to the processing requirements of aluminum substrates of different thicknesses and sizes. The aluminum substrate to be processed is placed on the top of the lifting platform 7, and the first servo motor 201 is started. The first servo motor 201 drives the threaded sleeve 203 to rotate through the first transmission rod 202. The threaded sleeve 203 engages with the threaded rod 204 to drive the lifting platform 7 upward. The lifting rod 4 slides synchronously along the limit rod 3 to guide the lifting platform 7 until the aluminum substrate rises to the preset processing height, at which point the first servo motor 201 stops and locks. Then, the device starts... The second servo motors 6 on both sides rotate synchronously in opposite directions, driving the ball screw 8 to rotate via the second transmission rod. The nut 9 moves along the ball screw 8 towards the center line of the operating table 1, driving the clamping plate 11 to move synchronously closer via the connecting rod 10. When the rubber pad 12 is tightly attached to both sides of the aluminum substrate and the preset clamping force is reached, the second servo motor 6 stops locking, completing the positioning and clamping of the aluminum substrate. After processing, the second servo motor 6 rotates in the opposite direction, driving the clamping plate 11 to reset. The first servo motor 201 runs in the opposite direction, causing the lifting platform 7 to descend, allowing the operator to remove the processed aluminum substrate. Throughout the process, the protective plate 13 provides safety protection, and the operator can observe the operating status of the internal components in real time through the inspection window 14 to ensure stable operation of the device.
