Description

Technical Field

[0001] This utility model relates to the field of spindle maintenance technology, and specifically to a spindle maintenance device. Background Technology

[0002] The machine tool spindle is the component that drives the workpiece or cutting tool to rotate. It is one of the key functional components of CNC machine tools, and its reliability level directly affects the overall reliability, processing efficiency, and processing accuracy of the machine.

[0003] A prior art spindle maintenance device, such as the utility model patent document with authorization announcement number "CN216781199U" and patent name "a maintenance and lubrication device for CNC spindle", discloses a spindle maintenance device including two base fabric layers, a placement area between the two base fabric layers, a fragrance piece in the placement area, and an elastic line in the shape of a ring around the two base fabric layers to clamp the fragrance piece.

[0004] The aforementioned patent document states that the sponge can lubricate the main shaft by moving the spiral linear motion of the annular body, but it cannot repeatedly lubricate a specific section of the main shaft, thus reducing the practicality of the device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by proposing a spindle maintenance device. This device solves the technical problem mentioned in the background art: the existing spindle maintenance device uses the spiral linear movement of a ring to drive a sponge to lubricate the spindle, which cannot repeatedly lubricate a specific section of the spindle, thus reducing the practicality of the device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A spindle maintenance device includes two parallel support plates, a movable ring slidably disposed between the two support plates, the movable ring having a hollow structure at its axis and a gear disk coaxially rotatably connected to one side of the movable ring, the gear disk having a hollow structure at its axis, the gear disk having a plurality of lubrication components for lubricating and applying oil to the spindle, and the movable ring having a drive component for driving the gear disk to rotate.

[0008] Working principle:

[0009] First, place the spindle requiring maintenance in the hollow structure between the moving ring and the gear plate. Then, the lubrication components can be placed close to the outer circumferential surface of the spindle. Next, the operator starts the drive assembly, which drives the gear plate to rotate. The rotation of the gear plate drives several lubrication components, which can lubricate the outer circumferential surface of the spindle. Then, the operator can change the position of the gear plate by changing the position of the moving ring, thereby changing the position of the lubrication components on the gear plate and thus expanding the area where the lubrication components lubricate the spindle.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, a lubrication component is provided, which can be closely attached to the outer circumferential surface of the spindle, thereby enabling the lubrication component to apply oil to the outer surface of the spindle.

[0012] Secondly, a drive assembly is provided, which can drive the gear plate to rotate. The rotation of the gear plate synchronously drives the lubrication assembly to rotate, so that the lubrication assembly can rotate on the outer surface of the spindle, thereby expanding the lubrication area that the lubrication assembly can apply oil to the spindle.

[0013] Third, a moving ring is provided. By driving the moving ring, the gear plate can be moved. The movement of the gear plate can drive the lubrication assembly to move along the spindle axis, thereby expanding the lubrication operation area of ​​the lubrication assembly on the spindle.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example:

[0021] like Figure 1 As shown, a spindle maintenance device includes two parallel support plates 1, with a movable ring 2 slidably disposed between the two support plates 1. A moving assembly for driving the movable ring 2 to move is disposed between the two support plates 1. The moving assembly includes a screw 20, a guide rod 21, two sliders 22, and a second motor 23. The screw 20 is rotatably disposed between the two support plates 1, and the guide rod 21 is fixed between the two support plates 1 and parallel to the screw 20. The two sliders 22 are respectively screwed to the screw 20 and slidably disposed on the guide rod 21. Both sliders 22 are fixedly connected to the outer ring of the movable ring 2. The second motor 23 is fixedly disposed on one of the support plates 1, and the output end of the second motor 23 is fixedly connected to the screw 20. The second motor 23 can drive the screw 20, and the rotation of the screw 20 can drive the sliders 22, so that the two sliders 22 can move between the two support plates 1, and in turn, the two sliders 22 can drive the movable ring 2 to move between the two support plates 1.

[0022] like Figure 1 and Figure 2 As shown, the moving ring 2 has a hollow structure at its axis, and a gear disk 3 is coaxially rotatably connected to one side of the moving ring 2. The gear disk 3 also has a hollow structure at its axis, and the inner diameter of the hollow structure of the gear disk 3 is larger than the inner diameter of the hollow structure of the moving ring 2. The main shaft can be placed in the hollow part of the axis of the moving ring 2 and the gear disk 3, which facilitates the lubrication operation of the main shaft by the subsequent lubrication assembly. The inner diameter of the hollow structure of the moving ring 2 is larger than the diameter of the main shaft to be lubricated. The moving ring 2 has several sliding grooves 16, and the inner ring of the gear disk 3 has a snap-fit ​​groove 17. Sliding blocks 18 are slidably installed in each of the sliding grooves 16. The engagement of the snap-fit ​​grooves 17 and the sliding blocks 18 facilitates the rotation of the gear disk 3 on the moving ring 2. The sliding blocks 18 are slidably connected to the snap-fit ​​grooves 17, and bolts 19 are screwed onto each of the sliding blocks 18. The bolts 19 are threaded to the inner wall of the sliding grooves 16, and the sliding blocks 18 in the sliding grooves 16 can be fixed by the bolts 19.

[0023] like Figure 2 and Figure 3As shown, the gear disk 3 is equipped with several lubrication components for lubricating the spindle. The lubrication components include a rotating rod, an oiling roller 5, and a spring telescopic rod 6. The rotating rod is hinged to the gear disk 3. The oiling roller 5 is rotatably mounted on the rotating rod and passes through the hollow space between the moving ring 2 and the gear disk 3. One end of the spring telescopic rod 6 is hinged to the gear disk 3, and the other end is hinged to the rotating rod. The cooperation between the rotating rod and the spring telescopic rod 6 allows the oiling roller 5 to fit tightly against the outer circumferential surface of the spindle. The spring telescopic rod 6 provides a certain buffer space. The outer wall of the oiling roller 5 is covered with a sponge 7. The oiling roller 5 has a placement cavity 8 for placing lubricating oil. The surface of the oiling roller 5 has several through holes 9 that are connected to the placement cavity 8. The lubricating oil in the placement cavity 8 can be transferred to the sponge 7 on the outer surface of the oiling roller 5 through the through holes 9. The oiling point of the oiling roller 5 into the placement cavity 8 can be sealed when the oiling roller 5 is working to prevent the lubricating oil in the placement cavity 8 from overflowing when the oiling roller 5 rotates.

[0024] like Figure 1 and Figure 4 As shown, the moving ring 2 is equipped with a drive assembly for driving the gear disk 3 to rotate. The drive assembly includes two rotating shafts 10, two gears 11, a first motor 12, two sprockets 13, and a chain 14. The two rotating shafts 10 horizontally pass through the moving ring 2 and are rotatably connected to the moving ring 2. The two gears 11 are respectively fixed on the two rotating shafts 10. The outer ring of the gear disk 3 has a toothed groove 15, and both gears 11 mesh with the toothed groove 15. The rotation of the rotating shafts 10 drives the gear disk 3 to rotate. The gear 11 on the rotating shaft 10 rotates, and the rotation of the gear 11 can cooperate with the tooth groove 15 on the gear disk 3 to drive the gear disk 3. The first motor 12 is fixed on the moving ring 2 and the output end of the first motor 12 is fixed to one of the rotating shafts 10. The two sprockets 13 are respectively fixed on the two rotating shafts 10. The chain 14 is sleeved on the outer ring of the two sprockets 13. The rotating shaft 10 is driven by the first motor 12. The rotating shaft 10 drives the two rotating shafts 10 to rotate synchronously through the sprockets 13 and the chain 14.

[0025] Working principle:

[0026] First, the operator places the spindle requiring lubrication in the hollow structure of the moving ring 2. The spring telescopic rod 6 automatically extends and retracts according to the curvature of the spindle surface, pushing the rotating rod 4 to make the oiling roller 5 tightly adhere to the outer circumferential surface of the spindle, ensuring contact between the oiling roller 5 and the outer surface of the spindle. Then, the operator starts the first motor 12, which drives one of the rotating shafts 10 to rotate. This rotating shaft 10 drives the sprocket 13 and the chain 14, so that the two rotating shafts 10 rotate synchronously. Consequently, the two gears 11 on the two rotating shafts 10 rotate synchronously. The rotation of the two gears 11 drives the gear disk 3 to rotate on the moving ring 2. The rotation of the gear disk 3 drives the rotating rod 4 and the spring telescopic rod 6 on the gear disk 3 to rotate along the spindle axis. Thus, the oiling roller 5 on the rotating rod 4 can perform oiling and lubrication operations on the outer circumferential surface of the spindle.

[0027] When the operator needs to increase the lubrication area of ​​the oiling roller 5, the operator starts the second motor 23, which drives the screw 20. The screw 20 drives the slider 22, so that the moving ring 2 moves along the axis of the main shaft under the action of the two sliders 22, thereby increasing the lubrication area of ​​the oiling roller 5 on the main shaft.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
