Description

Technical Field

[0001] This utility model relates to the field of clay model processing technology, and in particular to a multi-axis linkage positioning fixture for clay model processing. Background Technology

[0002] Clay models are solid scale models or full-size models made using industrial clay. They are mainly used for refining, reviewing, and showcasing the design of products (especially vehicles). During the clay model making process, the clay needs to be scraped after the initial clay model has been fixed.

[0003] A search revealed a Chinese patent publication number CN215240738U, which discloses a rapid positioning device for industrial design clay models. This patent uses a hydraulic rod to drive the support plate to rise and fall while a motor drives a screw to rotate and adjust the height of the adjustment disc, thereby achieving support and positioning for different models. However, the clay model requires scraping and other operations in different positions during the modification process. In this process, the user needs to change the model's posture to adjust the relative position between themselves and the clay model in order to process and modify different positions of the clay model. Due to the large weight of the clay model, the labor intensity is high. Utility Model Content

[0027] Example 1

[0028] A multi-axis linkage positioning fixture for clay model processing, such as Figures 1 to 3 As shown, the system includes a base 1. A first linear drive mechanism 2 is mounted on the top outer wall of the base 1. A second linear drive mechanism 3 is mounted on the moving end of the first linear drive mechanism 2. An electric turntable 4 is mounted on the moving end of the second linear drive mechanism 3. A support plate 5 for supporting the clay model is fixed to the rotating end of the electric turntable 4. The moving directions of the first linear drive mechanism 2 and the second linear drive mechanism 3 are perpendicularly intersecting. Two sets of clamping assemblies are mounted on the outer wall of the support plate 5, and the two sets of clamping assemblies are perpendicular to each other. A telescopic rod 15 is mounted on the inner wall of the base 1. The telescopic end of the telescopic rod 15 is fixedly connected to the bottom outer wall of the first linear drive mechanism 2. Guide rods 17 that slide vertically with the base 1 are fixed at both ends of the bottom outer wall of the first linear drive mechanism 2. An operation panel for operating and controlling the first linear drive mechanism 2, the second linear drive mechanism 3, the electric turntable 4, the telescopic rod 15, and the clamping assemblies is provided on one side of the base 1.

[0029] The first linear drive mechanism 2 includes a guide frame 12 and a threaded rod 13. The threaded rod 13 is rotatably connected to the inner wall of the guide frame 12. A drive motor for driving the threaded rod 13 to rotate is provided at one end of the guide frame 12. A moving platform 14 is slidably fitted on the inner wall of the guide frame 12. The moving platform 14 is threadedly fitted to the outer wall of the threaded rod 13. The second linear drive mechanism 3 has the same structure as the first linear drive mechanism 2. Two parallel moving grooves 18 are opened on the top outer wall of the base 1. Limit blocks are slidably fitted on the inner wall of the moving grooves 18. Another set of guide rods 17 are fixed on the bottom outer walls of both ends of the guide frame 12 in the second linear drive mechanism 3, which are vertically slidably fitted with the limit blocks. Folded protective covers 16 are provided on the top inner wall of the guide frame 12 and the top inner wall of the moving grooves 18. The two ends of the folded protective covers 16 on the top inner wall of the guide frame 12 are respectively connected to the inner wall of the guide frame 12 and the moving platform 14. The two ends of the folded protective covers 16 on the top inner wall of the moving grooves 18 are respectively connected to the limit blocks and the inner wall of the moving grooves 18.

[0030] The clamping assembly includes two sliding grooves 6 and a moving block 9. The two sliding grooves 6 are opened opposite to each other on the outer wall of the base 1. The moving block 9 is slidably engaged with the inner wall of the sliding groove 6. The inner wall of the sliding groove 6 is opened opposite to each other with a limiting groove 7. The moving block 9 is limited and slidably engaged with the inner wall of the limiting groove 7. A guide groove 8 is opened on one side of the inner wall of the sliding groove 6. A motor-bidirectional lead screw structure for driving the moving block 9 to move along the guide groove 8 is provided on the inner wall of the guide groove 8. A clamping rod 10 is fixedly connected to the top outer wall of the moving block 9. The clamping rod 10 is made of silicone material.

[0031] When fixing the clay model, the clay model is placed on the center of the top outer wall of the support plate 5. The motor-double-acting screw mechanism drives multiple moving blocks 9 to move along the sliding groove 6 towards the center of the support plate 5, so that the clamping rod 10 contacts the side wall of the clay model to clamp and fix the clay model. During the processing, the user controls the first linear drive mechanism 2, the second linear drive mechanism 3, the electric turntable 4, and the telescopic rod 15 through the operation panel to adjust the posture, position, and height of the model as needed. When adjusting the posture of the model, the electric turntable 4 drives the support plate 5 to rotate and change the angle of the model; when adjusting the position of the model, the electric turntable 4 drives the support plate 5 to rotate and change the angle of the model. The machine drives the threaded rod 13 to rotate, causing the moving table 14 to move along the guide frame 12. The model position is adjusted through the cooperation of the first linear drive mechanism 2 and the second linear drive mechanism 3. When adjusting the model height, the telescopic rod 15 pushes the first linear drive mechanism 2, the second linear drive mechanism 3, the electric turntable 4 and the support plate 5 to move upward as a whole. The guide rod 17 provides auxiliary guidance and support for the first linear drive mechanism 2 and the second linear drive mechanism 3. The folding protective cover 16 encloses the guide frame 12 and the moving groove 18 to prevent the sludge from the machining from falling into the guide frame 12 and the moving groove 18.

[0032] By incorporating a first linear drive mechanism 2, a second linear drive mechanism 3, an electric turntable 4, a telescopic rod 15, a guide rod 17, and a moving groove 18, the posture, position, and height of the model can be adjusted as needed, allowing users to easily scrape different parts of the clay model.

[0033] By providing a folding protective cover 16, the guide frame 12 and the moving groove 18 can be sealed off, preventing the sludge from the machining process from falling into the guide frame 12 and the moving groove 18.

[0034] Example 2

[0035] A multi-axis linkage positioning fixture for clay model processing is provided in this embodiment, which is based on embodiment 1 and makes the following improvements, such as... Figures 3 to 4As shown, the top outer wall of the movable block 9 has two parallel connecting holes. The bottom outer wall of the clamping rod 10 is fixedly connected to a connecting rod 19. The connecting rod 19 is inserted into one connecting hole, and a sealing plug 11 is inserted into the inner wall of the other connecting hole. The connecting rod 19 has a sliding cavity inside. Both ends of the inner wall of the sliding cavity are slidably connected to limit ball heads 20. The two limit ball heads 20 are connected to the same spring 21. The inner wall of the connecting hole is provided with an arc-shaped groove that cooperates with the limit ball head 20.

[0036] During processing, the clamping rod 10 will partially obstruct the clay model. If it is necessary to process these obstructed parts, the moving block 9 can be driven away from the clay model by a certain distance, and the positions of the clamping rod 10 and the sealing block 11 can be interchanged. At this time, the moving block 9 is driven to reset and clamp the clay model. At this time, the contact position between the clamping rod 10 and the clay model changes, which facilitates the processing of the clay model. When the clamping rod 10 is connected to the connecting hole, the connecting rod 19 is inserted into the connecting hole. The connecting hole squeezes the limiting ball head 20, causing the limiting ball head 20 to retract into the connecting rod 19. The spring 21 is compressed and deformed. When the limiting ball head 20 is aligned with the arc groove, the spring 21 pushes the limiting ball head 20 into the arc groove to fix the clamping rod 10.

[0037] By incorporating a sealing plug 11, a connecting rod 19, a limiting ball head 20, and a spring 21, the position of the clamping rod 10 can be easily adjusted, preventing the clamping rod 10 from obstructing part of the clay model and making it impossible to scrape and process the obstructed area.

[0038] Working principle: When fixing the clay model, the clay model is placed on the center of the top outer wall of the support plate 5. The motor-bidirectional screw mechanism drives multiple moving blocks 9 to move along the sliding groove 6 towards the center of the support plate 5, so that the clamping rod 10 contacts the side wall of the clay model to clamp and fix the clay model. During the processing, the user controls the first linear drive mechanism 2, the second linear drive mechanism 3, the electric turntable 4, and the telescopic rod 15 through the operation panel to adjust the posture, position, and height of the model as needed. When adjusting the posture of the model, the electric turntable 4 drives the support plate 5 to rotate and change the angle of the model; when adjusting the position of the model, the drive motor drives the screw rod 13 to rotate, causing the moving table 14 to move along the guide frame 12. The adjustment of the model position is achieved through the cooperation of the first linear drive mechanism 2 and the second linear drive mechanism 3; when adjusting the height of the model, the telescopic rod 15 pushes the first linear drive mechanism 2, the second linear drive mechanism 3, the electric turntable 4, and the support plate 5 to move upward as a whole, and the guide rod 17... The first linear drive mechanism 2 and the second linear drive mechanism 3 provide auxiliary guidance and support; the folding protective cover 16 encloses the guide frame 12 and the moving groove 18 to prevent the sludge from falling into the guide frame 12 and the moving groove 18 during processing; during processing, the clamping rod 10 will partially obstruct the sludge model. If it is necessary to process these obstructed parts, the moving block 9 can be driven away from the sludge model by a certain distance, and the positions of the clamping rod 10 and the sealing block 11 can be interchanged. At this time, the moving block 9 is driven to reset and clamp the sludge model. At this time, the contact position between the clamping rod 10 and the sludge model changes, which facilitates the processing of the sludge model. When the clamping rod 10 is connected to the connecting hole, the connecting rod 19 is inserted into the connecting hole, and the connecting hole squeezes the limiting ball head 20, causing the limiting ball head 20 to retract into the connecting rod 19. The spring 21 is compressed and deformed. When the limiting ball head 20 is aligned with the arc groove, the spring 21 pushes the limiting ball head 20 into the arc groove to fix the clamping rod 10.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
