Description

Technical Field

[0001] This utility model relates to the field of chuck technology, and in particular to a positioning device for machine tool chucks. Background Technology

[0002] Machine tool chuck positioning devices play a crucial role in the manufacturing industry, and are widely used in precision machining and automated production. With the continuous improvement of machining requirements, higher demands are being placed on the accuracy and flexibility of chuck positioning devices. In recent years, with the rapid development of intelligent and automated technologies, new positioning devices, through optimized design, can improve positioning accuracy, work efficiency, and adaptability, meeting more complex machining needs. In the future, machine tool chuck positioning devices will develop towards greater intelligence, higher precision, and greater flexibility, promoting the further development of intelligent manufacturing.

[0003] A search revealed an existing patent (publication number: CN221583401U) that discloses a machine tool chuck positioning device, comprising: an outer frame; first lead screws threadedly connected to both sides of the outer frame, a clamping block fixedly connected to the right end of the first lead screw, a limit plate fixedly connected to the left end of the first lead screw, a first bevel gear rotatably connected inside the outer frame, the first bevel gear being threadedly connected to the first lead screw, and a second bevel gear rotatably connected inside the outer frame. This utility model provides a machine tool chuck positioning device where the rotation of the second bevel gear drives the rotation of a third bevel gear, which in turn drives the rotation of a fourth bevel gear, which in turn drives the rotation of the first bevel gear. The rotation of the first bevel gear causes the first lead screw to move to the right. At this point, the two sets of first lead screws drive the clamping block to clamp and position the chuck. The same method can be used to clamp and position a fixed disc. This mechanism allows for rapid positioning of the chuck and the fixed disc.

[0004] However, in actual use, the fixed disc cannot be adjusted in position. This inability to adjust the position of the fixed disc has several adverse effects on the machine tool chuck positioning device. First, accuracy is limited because the inability to fine-tune the workpiece position may lead to machining errors and affect product quality. Second, adaptability is poor; the fixed disc cannot flexibly handle workpieces of different shapes or sizes, increasing production cycle and cost. Furthermore, this design lacks flexibility and cannot quickly respond to changing production demands, reducing production efficiency. The fixed structure also limits the development of automation levels, affecting the overall intelligence of the production line and reducing the advantages of automated production.

[0037] The card assembly is located inside the limit assembly, and the limit assembly limits the card assembly.

[0038] in,

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the lateral movement assembly includes first support rods 1 symmetrically slidably connected to both sides of the second support rod 2, which limit the second support rod 2. A first support plate 11 is fixedly connected to the outer wall of one end of the first support rod 1, supporting and fixing the first support plate 11. A first motor 12 is fixedly connected to the outer wall of the first support plate 11 near the first support rod 1, supporting and fixing the first motor 12. A first sprocket 13 is rotatably connected to the outer wall of the first support plate 11 away from the first support rod 1, supporting and fixing the first sprocket. 13 is used for limiting. The top rotating end of the first sprocket 13 is fixedly connected to the output end of the first motor 12. The first lead screw 14 is rotatably connected to the inner side of the first support rod 1. The first lead screw 14 passes through the first support plate 11 and is fixedly connected to the bottom rotating end of the first sprocket 13. The first motor 12 drives the first lead screw 14 to rotate through the first sprocket 13. The outer side of the middle section of the first lead screw 14 is threaded with the first moving table 15. The first lead screw 14 drives the first moving table 15 to move laterally. The first moving table 15 is fixedly connected to the second support rod 2. The first moving table 15 supports and fixes the second support rod 2.

[0040] like Figures 1 to 4As shown, the longitudinal moving assembly includes a second support plate 21 fixed to the top of one side of the second support rod 2. The second support rod 2 supports and fixes the second support plate 21. A second motor 22 is fixedly connected to the outer wall of the second support plate 21 near the second support rod 2, supporting and fixing the second motor 22. A second sprocket 23 is rotatably connected to the outer wall of the second support plate 21 away from the second motor 22, limiting the movement of the second sprocket 23. The rotating end of the second sprocket 23 near the second motor 22 is fixedly connected to the output end of the second motor 22. The second motor 22 drives the second sprocket 23 to move closer to the second motor 22. The rotating end on the side rotates. The second support rod 2 is rotatably connected to the inner side of the second lead screw 24. The second support rod 2 limits the second lead screw 24, allowing the second lead screw 24 to rotate inside the second support rod 2. The end of the second lead screw 24 near the second sprocket 23 passes through the second support plate 21 and is fixedly connected to the rotating end of the second sprocket 23. The second sprocket 23 drives the second lead screw 24 to rotate. The outer side of the middle section of the second lead screw 24 is threadedly connected to the second moving platform 25. The second lead screw 24 limits the second moving platform 25 and drives the second moving platform 25 to move. The outer walls on both sides of the second support rod 2 are provided with first sliding grooves 27.

[0041] Limiting rods 26 are fixedly connected to both sides of the bottom of the second moving platform 25. The limiting rods 26 are engaged with the first sliding groove 27. The first sliding groove 27 limits the limiting rods 26, and at the same time, the limiting rods 26 limit the second moving platform 25.

[0042] like Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the limiting assembly includes a limiting sleeve 3 fixed to the top of the second moving platform 25. The limiting sleeve 3 is supported and fixed by the second moving platform 25. Three through holes 31 are provided in the middle section of the limiting sleeve 3. Limiting balls 32 are slidably connected to the inner side of each through hole 31, limiting the limiting balls 32 through the through holes 31. The two ends of the through holes 31 are tapered, limiting the limiting balls 32 and preventing them from falling out. A retaining ring 33 is fixedly connected to the top of the limiting sleeve 3, supporting and fixing the retaining ring 33. A sliding sleeve 34 is slidably connected to the outer side of the limiting sleeve 3. The limiting sleeve 3 limits the sliding sleeve 34, allowing the sliding sleeve 34 to slide outside the limiting sleeve 3. An extension chamber 35 is provided inside the sliding sleeve 34. By providing the extension chamber 35 inside the sliding sleeve 34, the outward movement of the limiting ball 32 can be increased. A groove 36 is provided at the top of the sliding sleeve 34. A spring 37 is fixedly connected inside the groove 36. The groove 36 supports and fixes the spring 37. The top end of the spring 37 is fixedly connected to the bottom of the retaining ring 33. The retaining ring 33 limits the top of the spring 37. A second sliding groove 38 is evenly distributed inside the limiting sleeve 3.

[0043] like Figure 9 and Figure 10 As shown, the clamping plate assembly includes a clamping platform 4 slidably connected to the inner side of the limiting sleeve 3. The clamping platform 4 is limited by the limiting sleeve 3. A groove 41 corresponding to the limiting ball 32 is opened on the outer side of the bottom of the clamping platform 4. The limiting ball 32 and the groove 41 are engaged with each other, thereby fixing the limiting sleeve 3 and the clamping platform 4 relatively. A clamping rod 42 corresponding to the second sliding groove 38 is fixedly connected to the outer wall of the clamping platform 4. The second sliding groove 38 and the clamping rod 42 are engaged with each other, thereby limiting the angle of the clamping platform 4.

[0044] Specifically, the positioning device originally intended for machine tool chucks is used as follows:

[0045] First, pull the sliding sleeve 34 upward, and at the same time compress the spring 37 through the sliding sleeve 34. The sliding sleeve 34 also drives the range extender 35 to move to the top, thereby aligning the range extender 35 with the limit ball 32, so that the limit ball 32 can move into the range extender 35.

[0046] Rotate the clamping platform 4 to align the locking rod 42 fixed on the outer wall of the clamping platform 4 with the second sliding groove 38 inside the limiting sleeve 3, and insert the clamping platform 4 into the limiting sleeve 3. Then, release the sliding sleeve 34 and push the sliding sleeve 34 to the bottom with the retaining ring 33 as the stress point through the spring 37. The sliding sleeve 34 squeezes the limiting ball 32, forcing the limiting ball 32 to move into the through hole 31, and causing the through hole 31 to move into the slot 41, thereby locking and fixing the limiting sleeve 3 and the clamping platform 4.

[0047] When moving the position of the clamping platform 4, the first motor 12 first drives the first lead screw 14 to rotate via the first sprocket 13, and the first lead screw 14 drives the first moving platform 15 to move laterally. Then, the second motor 22 drives the second lead screw 24 to rotate via the second sprocket 23, and the second lead screw 24 drives the second moving platform 25 to move longitudinally, thereby adjusting the position of the clamping platform 4.

[0048] 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.
