It includes a mounting block with two symmetrically mounted fixing structures. Each fixing structure comprises a mounting base rod, a fixing block, and a mounting shaft. The fixing block is mounted on the outer end of the mounting base rod. Two mounting shafts are symmetrically mounted on the mounting base rod. A limit baffle is provided at the upper end of the mounting block, simultaneously located at the upper ends of both mounting base rods. A connecting block is provided at the lower end of the limit baffle, and an anti-detachment block is provided at the lower end of the connecting block. Two limit springs are symmetrically mounted at both ends of the anti-detachment block. This utility model, a spring positioning and clamping mechanism based on CNC machine tools, belongs to the field of positioning and clamping mechanisms. By setting up fixing structures, limit baffles, fixing toothed plates, and limit springs, their mutual cooperation simplifies the steps of fixing parts, thereby ultimately improving the efficiency of part fixing.

[0004] The following problems also exist in this solution: when adjusting the two mounting base rods to limit the ring part, the two mounting base rods need to be adjusted separately, which is cumbersome. In addition, the height of the mounting base rods is fixed, which is not convenient for limiting ring parts of different heights. Therefore, there are certain drawbacks.

[0005] Therefore, in order to solve the above problems, this application provides a spring positioning and clamping mechanism based on CNC machine tools. Utility Model Content

[0008] Preferably, the outer ring surface of the adjusting bolt is threadedly connected to the inside of the operating table, and the top of the adjusting bolt is rotatably connected to the bottom of the fixed seat. Fixed rods are symmetrically installed on the bottom of the operating table on both sides of the adjusting bolt, and the top end of the fixed rod passes through the operating table and is connected to the bottom of the fixed seat.

[0009] Preferably, a groove is formed on the top of the fixed seat between the two sliding grooves, a support rod is installed between the two inner side walls of the groove, a movable block is installed on the outer ring surface of the support rod, the outer ring surface of the support rod is slidably connected to the inside of the movable block, and compression springs are installed on both sides of the support rod on the outside of the movable block.

[0010] Preferably, a limiting plate is installed on the top of the movable block, a pull ring is installed on one outer end of the limiting plate, a first limiting tooth groove is installed on both bottom ends of the limiting plate, and a second limiting tooth groove is installed on one top end of the slider. The first limiting tooth groove and the second limiting tooth groove are mirror images of each other.

[0011] Preferably, limit grooves are formed on both inner side walls of the slide, and limit rods are installed on both outer side surfaces of the slider, respectively located inside the two limit grooves.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This spring positioning and clamping mechanism based on CNC machine tools allows the height of the fixed base to be changed by rotating the adjusting bolt, thereby adjusting the height of the slider and the limiting block. This facilitates the fixing of ring-shaped parts of different heights. When the limiting plate moves away from the two sliders, the first limiting tooth groove and the second limiting tooth groove at both ends of the bottom of the limiting plate separate, thereby releasing the restriction on the slider sliding inside the groove. By pulling the sliding rod to move inside the adjusting groove, the movable plate is moved synchronously. When the movable plate moves, it squeezes the cylindrical block through the inclined grooves at both ends, thereby driving the two sliders to move relative to or in opposite directions. This facilitates the synchronous adjustment of the movement of the two sliders to limit the movement of tubular parts, making the operation more convenient. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1 - Figure 6 This application will be described in further detail.

[0023] A spring positioning and clamping mechanism based on a CNC machine tool, referring to Figure 1 - Figure 6The system includes an operating platform 1. Support legs 2 are installed at the four corners of the bottom of the operating platform 1. Adjusting bolts 3 are installed at the bottom of the operating platform 1. One end of the top of the adjusting bolts 3 passes through the operating platform 1 and is installed with a fixed seat 4. Slide grooves 401 are symmetrically opened at both ends of the top of the fixed seat 4. Slide sliders 5 are installed inside the slide grooves 401. Limit blocks 6 are installed at one end of the slide sliders 5. Support frames 7 are symmetrically installed at both ends of the top of the operating platform 1. A top plate 8 is installed between the tops of the support frames 7. Adjusting grooves 801 are symmetrically opened at the top of the top plate 8. Slide rods 9 are installed inside the adjusting grooves 801. Movable plates 10 are installed at the bottom of the slide rods 9 and below the top plate 8. Inclined grooves 1001 are symmetrically opened at both ends of the top of the movable plates 10. Cylindrical blocks 11 are installed at the top of the slide sliders 5 and inside the inclined grooves 1001.

[0024] Reference Figure 2 The outer ring surface of the adjusting bolt 3 is threadedly connected to the inside of the operating table 1, and the top of the adjusting bolt 3 is rotatably connected to the bottom of the fixed seat 4. By rotating the adjusting bolt 3, the height of the fixed seat 4 can be changed, thereby adjusting the height of the slider 5 and the limit block 6, which facilitates the fixing of ring parts of different heights. Fixed rods 12 are symmetrically installed at the bottom of the operating table 1 and on both sides of the adjusting bolt 3. The top end of the fixed rod 12 passes through the operating table 1 and is connected to the bottom of the fixed seat 4. By setting two sets of fixed rods 12, the stability of the lifting and lowering of the fixed seat 4 is increased.

[0025] Reference Figure 3 - Figure 5 A groove 402 is formed on the top of the fixed base 4 between the two sliding grooves 401. A support rod 13 is installed between the two inner side walls of the groove 402. A movable block 14 is installed on the outer ring surface of the support rod 13. The outer ring surface of the support rod 13 is slidably connected to the inside of the movable block 14. Compression springs 15 are installed on both sides of the movable block 14 on the outside of the support rod 13. When the movable block 14 moves towards one end of the groove 402, it will compress one of the compression springs 15. A limit plate 16 is installed on the top of the movable block 14. A pull ring 17 is installed on one end of the limiting plate 16. The bottom ends of the limiting plate 16 are equipped with first limiting grooves 18. By pulling the pull ring 17 outward, the movable block 14 can be moved through the limiting plate 16. The top end of the slider 5 is equipped with a second limiting groove 19. The first limiting groove 18 and the second limiting groove 19 are mirror images of each other. When the limiting plate 16 moves away from the two sliders 5, the first limiting grooves 18 and the second limiting grooves 19 at the bottom ends of the limiting plate 16 separate, thereby releasing the restriction on the slider 5 to slide inside the slide groove 401.

[0026] Reference Figure 5 - Figure 6Limiting grooves 403 are provided on both inner side walls of the slide groove 401. Limiting rods 20 are installed on both outer sides of the slider 5 and inside the two limiting grooves 403 respectively. When the slider 5 moves inside the slide groove 401, it synchronously drives the limiting rods 20 on both sides to slide inside the two limiting grooves 403. The stability of the slider 5 movement is increased by setting the limiting rods 20.

[0027] Reference Figure 1 - Figure 3 The bottom ends of the slide rod 9 are slidably connected to the interior of the two adjustment slots 801, and the top of the movable plate 10 is in contact with the bottom of the support frame 7. By pulling the slide rod 9 to move inside the adjustment slot 801, the movable plate 10 is moved synchronously. The contact between the movable plate 10 and the bottom of the support frame 7 increases its movement stability. When the movable plate 10 moves, it will squeeze the cylindrical block 11 to move through the inclined slots 1001 at both ends, thereby driving the two sliders 5 to move relative to or in opposite directions, which makes it easy to adjust the movement of the two sliders 5 synchronously to limit the tubular parts.

[0028] The implementation principle of a spring positioning clamping mechanism based on a CNC machine tool according to an embodiment of this application is as follows: During the use of this clamping mechanism, the height of the fixed seat 4 can be changed by rotating the adjusting bolt 3, thereby adjusting the height of the slider 5 and the limiting block 6, which facilitates the fixing of ring parts of different heights. By setting two sets of fixing rods 12, the stability of the lifting of the fixed seat 4 is increased. By pulling the pull ring 17 outward, the movable block 14 can be moved through the limiting plate 16. When the movable block 14 moves towards one end of the support rod 13 in the groove 402, it will compress the compression spring 15 on one side. When the limiting plate 16 moves away from the two sliders 5, the first limiting tooth groove 18 and the second limiting tooth groove 19 at both ends of the bottom of the limiting plate 16 separate, thereby releasing the restriction on the slider 5 sliding inside the groove 401. By pulling the slide bar 9 to move inside the adjusting groove 801, the movable plate 10 is moved synchronously. The movable plate 10 is in contact with the bottom of the support frame 7, which increases its movement stability. When the movable plate 10 moves, it will squeeze the cylindrical block 11 through the inclined grooves 1001 at both ends, thereby driving the two sliders 5 to move relative to each other or in opposite directions. When the slider 5 moves inside the sliding groove 401, it will synchronously drive the limiting rods 20 on both sides to slide inside the two limiting grooves 403. By setting the limiting rods 20, the stability of the slider 5 movement is increased, which makes it easier to adjust the movement of the two sliders 5 synchronously to limit the tubular parts. The operation is more convenient. After the two sliders 5 are adjusted, the pull ring 17 is released, the compression spring 15 is reset, and the first limiting tooth groove 18 is engaged with the second limiting tooth groove 19, thereby limiting the slider 5.
