Description

Technical Field

[0001] This utility model relates to the field of workpiece support platform technology, specifically a multi-degree-of-freedom workpiece support platform for laser rapid prototyping machines. Background Technology

[0002] Laser rapid prototyping machines are advanced equipment that integrate laser technology, CAX technology, automatic control technology, and new materials technology. They use principles such as photopolymerization three-dimensional modeling, layered solid manufacturing, selective laser sintering, and laser cladding to rapidly transform design models into physical prototypes. They feature high manufacturing efficiency, flexible design, and high processing precision, which can significantly shorten product development cycles, meet complex and unique design requirements, and reduce costs. During the operation of a laser rapid prototyping machine, a support platform is required to support the workpiece.

[0003] A search revealed Chinese patent CN212264431U, which discloses a workpiece support platform for a riveting machine. The platform includes a base plate with a rotating rod rotatably mounted at its top center. A placement plate is concentrically connected to the top of the rotating rod. The top of the placement plate has three sets of center-pointing strip openings arranged in a ring. A threaded rod is rotatably mounted within each opening on the top of the placement plate, with one end extending through the placement plate and fixedly fitted with a knob. A threaded sleeve is threaded onto the outer side of the threaded rod, and guide blocks are fixedly connected to both sides of the threaded sleeve. A clamping seat is fixedly mounted at the top of the threaded sleeve. A U-shaped connecting rod is fixedly mounted on the side wall of the placement plate. This invention allows for better clamping of the entire device, facilitating the subsequent riveting process. Furthermore, it allows for angle adjustment and fixation after the workpiece is clamped, further simplifying the process.

[0004] However, the above design still has shortcomings. When the workpiece support platform is used to support the workpiece of a laser rapid prototyping machine, it is difficult to freely adjust the fixed workpiece, which makes it inconvenient to process the workpiece and reduces the processing efficiency of the workpiece.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0006] The purpose of this invention is to provide a multi-degree-of-freedom workpiece support platform for laser rapid prototyping machines, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-degree-of-freedom workpiece support platform for a laser rapid prototyping machine, comprising a support, an installation cavity inside the support, a hydraulic push rod installed inside the installation cavity, a worktable fixedly connected to the output end of the hydraulic push rod, limit grooves extending from both sides of the top of the support into the interior, a limit vertical plate movably disposed inside the limit groove, and the top of the limit vertical plate fixedly connected to the lower surface of the worktable, limit sliding grooves on both sides of the limit groove, a limit slider movably disposed inside the limit sliding groove, and the limit slider fixedly connected to the outer wall of the limit vertical plate, a first forward and reverse motor installed inside the worktable, a threaded rod fixedly connected to the output end of the first forward and reverse motor, a moving block threadedly connected to the outer wall of the threaded rod, a crossbar movably disposed through the lower surface of the moving block, a transmission block fixedly connected to the top of the moving block, and a placement plate fixedly connected to the top of the transmission block.

[0008] As a further embodiment of this utility model: a first limiting plate is fixedly connected to both sides of the top of the placement plate, and a second forward and reverse motor is installed on the right side inside the placement plate, with a bidirectional screw fixedly connected to the output end of the second forward and reverse motor.

[0009] As a further embodiment of this utility model: a threaded block is threadedly connected to the outer wall of the bidirectional screw, and a limit rod is movably provided through the lower end surface of the threaded block.

[0010] As a further embodiment of this utility model: a connecting block is fixedly connected to the top of the threaded block, and a second limiting plate is fixedly connected to the top of the connecting block.

[0011] As a further embodiment of this utility model: the top of both the second limiting plate and the first limiting plate are provided with a limiting screw threaded through, and the bottom of the limiting screw is fixedly connected to a limiting block.

[0012] As a further embodiment of this utility model: a control panel is installed on the front end face of the support, a bracket is fixedly connected to the bottom of the support, and support blocks are fixedly connected to the four corners of the bottom of the bracket.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-5This utility model provides an embodiment of a multi-degree-of-freedom workpiece support platform for a laser rapid prototyping machine, comprising a support 3, an installation cavity 21 inside the support 3, a hydraulic push rod 22 installed inside the installation cavity 21, and a worktable 2 fixedly connected to the output end of the hydraulic push rod 22. Limiting grooves 24 are formed on both sides of the top of the support 3 extending into the interior. Limiting vertical plates 23 are movably arranged inside the limiting grooves 24, and the top of the limiting vertical plates 23 is fixedly connected to the lower surface of the worktable 2. The limiting grooves 24 have openings on both sides... The limiting slide 25 has a limiting slider 26 inside, and the limiting slider 26 is fixedly connected to the outer wall of the limiting vertical plate 23. The worktable 2 is equipped with a first forward and reverse motor 11. The output end of the first forward and reverse motor 11 is fixedly connected to a threaded rod 10. The outer wall of the threaded rod 10 is threadedly connected to a moving block 14. A crossbar 12 is movably provided through the lower end surface of the moving block 14. A transmission block 13 is fixedly connected to the top of the moving block 14. A placement plate 1 is fixedly connected to the top of the transmission block 13.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, during use, after the workpiece is fixed, the first forward and reverse motor 11 can be started through the control panel 5. The output end of the first forward and reverse motor 11 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 drives the moving block 14 to move. The movement of the moving block 14 drives the placement plate 1 to move through the transmission block 13, thereby facilitating the adjustment of the horizontal position of the workpiece. At the same time, the output end of the hydraulic push rod 22 drives the worktable 2 to move. The movement of the worktable 2 drives the placement plate 1 to move, thereby facilitating the adjustment of the height position of the workpiece. By facilitating the horizontal and vertical position adjustment of the fixed workpiece, it is easier to process the workpiece, thereby improving the processing efficiency of the workpiece. This solves the problem that when the above-mentioned workpiece support platform is applied to the workpiece support of the laser rapid prototyping machine, it is difficult to freely adjust the fixed workpiece, which makes it inconvenient to process the workpiece and reduces the processing efficiency of the workpiece.

[0029] Specifically: By setting the limiting groove 24 and the limiting vertical plate 23, when the worktable 2 moves, it will drive the limiting vertical plate 23 to move inside the limiting groove 24, which can improve the stability of the worktable 2 during the movement process. Through the cooperation of the limiting slide 25 and the limiting slider 26, the limiting vertical plate 23 can be limited to prevent the limiting vertical plate 23 from detaching from the limiting groove 24.

[0030] First limiting plates 8 are fixedly connected to both sides of the top of the placement plate 1. A second forward and reverse motor 18 is installed on the right side inside the placement plate 1. A bidirectional screw 20 is fixedly connected to the output end of the second forward and reverse motor 18. A threaded block 17 is threadedly connected to the outer wall of the bidirectional screw 20. A limiting rod 19 is movably provided through the lower end surface of the threaded block 17. A connecting block 16 is fixedly connected to the top of the threaded block 17. A second limiting plate 15 is fixedly connected to the top of the connecting block 16. A limiting screw 7 is threadedly provided through the top of both the second limiting plate 15 and the first limiting plate 8. A limiting block 9 is fixedly connected to the bottom of the limiting screw 7. A control panel 5 is installed on the front end face of the support 3. A bracket 4 is fixedly connected to the bottom of the support 3. Support blocks 6 are fixedly connected to the four corners of the bottom of the bracket 4.

[0031] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, in use, the workpiece is first placed between two adjacent first limiting plates 8 and second limiting plates 15. Each placement plate 1 has two sets of first limiting plates 8 and second limiting plates 15, which can simultaneously fix two workpieces, thereby further improving the processing efficiency of the workpiece. When it is necessary to fix the workpiece, the output end of the second forward and reverse motor 18 can drive the bidirectional screw 20 to rotate. The rotation of the bidirectional screw 20 drives the two threaded blocks 17 to move in a direction away from each other. The movement of the two threaded blocks 17 drives the two second limiting plates 15 to move in a direction away from each other through the two connecting blocks 16. Together with the first limiting plate 8, the two sides of the workpiece are effectively limited and fixed. Then, the limiting screw 7 is rotated to drive the limiting block 9 to move downward until the limiting block 9 contacts the top of the workpiece and limits and fixes it again. By facilitating the fixation of the two sides and the top of the workpiece, the fixing effect of the workpiece can be effectively improved.

[0032] Working principle: In this application, after the workpiece is fixed, the first forward and reverse motor 11 can be started through the control panel 5. The output end of the first forward and reverse motor 11 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 drives the moving block 14 to move. The movement of the moving block 14 drives the placement plate 1 to move through the transmission block 13, thereby facilitating the adjustment of the horizontal position of the workpiece. At the same time, the output end of the hydraulic push rod 22 drives the worktable 2 to move. The movement of the worktable 2 drives the placement plate 1 to move, thereby facilitating the adjustment of the height position of the workpiece. By facilitating the horizontal and vertical position adjustment of the fixed workpiece, it is easier to process the workpiece, thereby improving the processing efficiency. Secondly, the workpiece is placed between two adjacent first limiting plates 8 and second limiting plates 15, and... Each placement plate 1 has two sets of first limiting plates 8 and second limiting plates 15, which can simultaneously fix two workpieces, thereby further improving the workpiece processing efficiency. When it is necessary to fix the workpiece, the output end of the second forward and reverse motor 18 can drive the bidirectional screw 20 to rotate. The rotation of the bidirectional screw 20 drives the two threaded blocks 17 to move in a direction away from each other. The movement of the two threaded blocks 17 drives the two second limiting plates 15 to move in a direction away from each other through the two connecting blocks 16. Together with the first limiting plate 8, the two sides of the workpiece are effectively limited and fixed. Then, the limiting screw 7 is rotated to drive the limiting block 9 to move downward until the limiting block 9 contacts the top of the workpiece and limits and fixes it again. By facilitating the fixation of the sides and top of the workpiece, the fixation effect of the workpiece can be effectively improved.
