Description

Technical Field

[0001] This utility model relates to the field of spindle box machining and positioning fixtures, specifically to a CNC machine tool spindle box machining and positioning fixture. Background Technology

[0002] The CNC machine tool spindle box machining positioning fixture is an auxiliary device specifically designed for the machining process of CNC machine tool spindle boxes. Its core function is to ensure that the spindle box maintains the correct position and posture during machining through precise positioning and stable clamping, thereby meeting the requirements of high-precision machining.

[0003] Traditional CNC machine tool spindle box machining positioning fixtures mostly rely on adjusting the position of the fixture and then placing the spindle box on top for fixation. However, they cannot adjust the position of the fixture according to the height. Fixed fixtures can only fix the spindle box in place, but some shaking will still occur during the machining process, which will affect the machining effect.

[0004] Therefore, it is necessary to invent a CNC machine tool spindle box machining and positioning fixture to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning fixture for machining CNC machine tool spindle boxes. By opening the first small cylinder switch, the connecting frame and the eccentric pressure roller are pushed, causing the eccentric pressure roller to press on the support plate. This allows the pressure head at the front end of the pressure plate to press down on the top of the spindle box, thereby strengthening the overall positioning stability. Simultaneously, by opening the second small cylinder on both sides, the push plate is pushed to squeeze the roller and the movable block, causing the movable block to rotate on the support seat. This causes the rear side of the movable block to lift up while the front pressure block presses down on the outside of the spindle box, thereby strengthening the fixation. This solves the problem mentioned in the background art of traditional CNC machine tool spindle box machining positioning fixtures, which mostly fix the spindle box by adjusting the position of the fixture, but cannot adjust the position of the fixture according to the height. Similarly, fixed fixtures can only fix the spindle box in place, but some shaking will still occur during the machining process, which will affect the machining effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC machine tool spindle box machining positioning fixture, including a fixture base for supporting the entire positioning fixture;

[0007] Mounting slots are all formed on the upper surface of the tooling base. First sliders are slidably connected to the inside of both sides of the mounting slots. A screw is fixedly connected to the upper end of the first slider. A handle is threaded to the outside of the screw. A support plate is rotatably connected above the handle. A movable shaft runs through the inside of the support plate, and the inner end of the movable shaft is fixedly connected to the inner side of the pressure plate. A pressure head is fixedly installed below the front end of the pressure plate. A movable frame is hinged to the upper rear side of the pressure plate. A first small cylinder is fixedly connected to the outer side of the movable frame. A connecting frame is hinged to the output end of the first small cylinder. An eccentric pressure roller is fixedly connected to the lower part of the connecting frame.

[0008] The second slider slides inside the tooling base. A second fastening nut is threaded to the rear side of the second slider. A support base is fixedly connected to the front side of the second slider. A movable block is hinged to the rear side of the support base. A pressure block is fixedly connected to the inner front end of the movable block. A roller is rotatably connected to the rear side of the movable block. A second small cylinder is fixedly connected to the lower rear side of the support base. A push plate is fixedly connected to the output end of the second small cylinder.

[0009] Preferably, a washer is fitted around the outside of the screw, and a first fastening nut is threaded onto the upper part of the washer.

[0010] Preferably, the screw passes through the support plate and the pressure plate, and the pressure plate is rotatably connected to the support plate.

[0011] Preferably, the eccentric pressure roller is located inside the pressure plate and is rotatably connected to the pressure plate, with one side of the eccentric pressure roller abutting against the upper part of the support plate.

[0012] Preferably, the push plate is attached to the back of the support base, and the outer side of the push plate is at an angle.

[0013] Preferably, a third slider is slidably connected to the rear inner side of the tooling base, and a positioning seat is fixedly connected above the third slider.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention, through the arrangement of a handle, support plate, movable shaft, pressure plate, pressure head, movable frame, first small cylinder, connecting frame, eccentric pressure roller, movable block, pressure block, and push plate, not only clamps and fixes the spindle box according to its height but also enhances the stability of the positioning. By rotating the handle according to the height of the spindle box, the entire support plate and pressure plate are raised and lowered. When raised to the required height, the first small cylinder switch is turned on to push the connecting frame and eccentric pressure roller, so that the eccentric pressure roller presses on the support plate, and the pressure head at the front end of the pressure plate presses down on the top of the spindle box, thereby enhancing the overall stability of the positioning. At the same time, by opening the second small cylinder on both sides, the push plate is pushed to squeeze the roller and movable block, so that the movable block rotates on the support seat, causing the rear side of the movable block to tilt up while the front pressure block presses down on the outside of the spindle box, thereby enhancing the fixation.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-6 The CNC machine tool spindle box machining positioning fixture shown includes a fixture base 1, which is used to support the entire positioning fixture;

[0027] Mounting slots 2 are all opened on the upper surface of the tooling base 1. The two sides of the mounting slot 2 are slidably connected to the first slider 3. The upper end of the first slider 3 is fixedly connected to the screw 4. The screw 4 is threadedly connected to the handle 7. The upper part of the handle 7 is rotatably connected to the support plate 8. The inside of the support plate 8 is through the movable shaft 9, and the inner end of the movable shaft 9 is fixedly connected to the inner side of the pressure plate 10. The pressure head 11 is fixedly set below the front end of the pressure plate 10. The upper rear side of the pressure plate 10 is hinged to the movable frame 12. The outer side of the movable frame 12 is fixedly connected to the first small cylinder 13. The output end of the first small cylinder 13 is hinged to the connecting frame 14. The lower part of the connecting frame 14 is fixedly connected to the eccentric pressure roller 15.

[0028] The second slider 16 slides inside the tooling base 1. A second fastening nut 17 is threadedly connected to the rear side of the second slider 16. A support base 18 is fixedly connected to the front side of the second slider 16. A movable block 19 is hinged to the rear side of the support base 18. A pressure block 20 is fixedly connected to the inner front end of the movable block 19. A roller 21 is rotatably connected to the rear side of the movable block 19. A second small cylinder 22 is fixedly connected to the lower rear side of the support base 18. A push plate 23 is fixedly connected to the output end of the second small cylinder 22. Turning on the first small cylinder 13 pushes the connecting frame 14 and the eccentric pressure roller 15, causing the eccentric pressure roller 15 to press on the support plate 8, and causing the pressure head 11 at the front end of the pressure plate 10 to press down on the top of the spindle box, thereby strengthening the overall positioning stability. At the same time, by turning on the second small cylinder 22 on both sides, the push plate 23 is pushed to squeeze the roller 21 and the movable block 19, causing the movable block 19 to rotate on the support seat 18, causing the rear side of the movable block 19 to lift up while the front pressure block 20 presses on the outside of the spindle box, thereby strengthening the fixation.

[0029] like Figure 1 and Figure 2 As shown, a washer 5 is sleeved on the outside of the screw 4, and a first fastening nut 6 is threaded on the top of the washer 5. When the first fastening nut 6 is loosened, the first slider 3 can move inside the tooling base 1. When the first fastening nut 6 is tightened, the first slider 3 will be fixed inside the tooling base 1. The distance of the first slider 3 in the tooling base 1 can be adjusted according to the length of the spindle box.

[0030] like Figure 2As shown, the screw 4 passes through the support plate 8 and the pressure plate 10. The pressure plate 10 is rotatably connected to the support plate 8. By rotating the handle 7, the support plate 8 and the pressure plate 10 can be raised and lowered to adjust the height of the spindle box. The pressure plate 10 rotates inside the support plate 8, which causes the subsequent eccentric pressure roller 15 to rotate and push the rear side of the pressure plate 10 to tilt up. At the same time, the front pressure head 11 will press tightly on the top of the spindle box.

[0031] like Figure 3 As shown, the eccentric pressure roller 15 is located inside the pressure plate 10 and is rotatably connected to the pressure plate 10. One side of the eccentric pressure roller 15 abuts against the support plate 8. When the first small cylinder 13 pushes the eccentric pressure roller 15 to flip, the protruding part of the eccentric pressure roller 15 abuts against the support plate 8, thereby causing the rear side of the pressure plate 10 to tilt up and the front pressure head 11 to press against the top of the spindle box.

[0032] like Figure 4 and Figure 5 As shown, the push plate 23 is attached to the back of the support base 18. The outer side of the push plate 23 is at an angle. By opening the switch of the second small cylinder 22, the push plate 23 is pushed up and down. Since the outer side of the push plate 23 is at an angle, the roller 21 and the movable block 19 are squeezed and lifted up on the back side of the support base 18. At the same time, the pressure block 20 on the front side will press on the outside of the spindle box to enhance stability.

[0033] like Figure 1 and Figure 6 As shown, a third slider 24 is slidably connected to the rear side of the tooling base 1. A positioning seat 25 is fixedly connected above the third slider 24. The distance between the third slider 24 and the tooling base 1 is adjusted by the third slider 24. The positioning seat 25 is used to hold the spindle box and enhance the stability of the positioning.

[0034] The working principle of this practical tool is as follows: First, adjust the distance between the two sets of first sliders 3, second sliders 16, and third sliders 24 according to the length and width of the CNC machine tool spindle box. After adjusting the position, tighten the first fastening nut 6 and the second fastening nut 17 to limit and fix them. Next, according to the height of the spindle box, rotate the handle 7 on the outside of the screw 4 to drive the entire support plate 8 and pressure plate 10 to rise and fall. When the required height is reached, place the spindle box on top of the tooling base 1, with its rear side abutting against the outside of the positioning seat 25. Then, turn on the switch of the first small cylinder 13 to push the connecting frame 14 and the eccentric pressure roller 15. The eccentric pressure roller 15 is flipped so that its protruding position abuts against the support plate 8, causing the rear side of the pressure plate 10 to tilt up. This allows the front pressure head 11 to press against the top of the spindle box, enhancing the overall positioning stability. Then, by opening the switch of the second small cylinder 22 on the outside of the support base 18, the push plate 23 is pushed up and down. The outer side of the push plate 23 is at an angle, which squeezes the roller 21 and the movable block 19 to tilt up on the rear side of the support base 18. At the same time, the front pressure block 20 presses against the outside of the spindle box, enhancing stability. This completes the process of using the CNC machine tool spindle box machining positioning fixture.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
