Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-6The utility model provides a technical solution: a lubrication device for a CNC lathe, comprising a first screw barrel 2, the first screw barrel 2 is threadedly connected to a second screw barrel 3, a sponge 10 is installed in the second screw barrel 3, the sponge 10 is filled with lubricating oil, and an extrusion component for extruding the sponge 10 is installed on the first screw barrel 2.

[0023] The extrusion assembly includes a cylinder 6, which is fixedly mounted on the top of the first screw barrel 2. The output end of the cylinder 6 is connected to a cylinder rod 7, which extends into the interior of the first screw barrel 2 and is fixedly mounted with a push plate 9, which is adapted to the second screw barrel 3 and slidably matched with the inner wall of the second screw barrel 3. The outer peripheral cover of the cylinder 6 is provided with a shell 1, which is fixedly mounted with the first screw barrel 2. The shell 1 plays a role in protecting the cylinder 6.

[0024] The bottom of the second screw barrel 3 is fixedly installed with a lubricating base plate 4, which can be deformed and is made of elastic material. The bottom of the lubricating base plate 4 is evenly fixedly installed with multiple brush fixing components 5, which include a hollow screw groove 16, which is fixedly matched with the bottom surface of the lubricating base plate 4, and the bottom of the hollow screw groove 16 is threadedly connected with a hollow screw 15, which passes through the hollow screw groove 16, and a baffle is fixedly installed at the bottom of the hollow screw 15 to prevent the hollow screw 15 from completely entering the hollow screw groove 16. Three arc plates 18 are fixedly installed on the top of the hollow screw 15, and the three arc plates 18 are arranged in a circumferential array. The three arc plates 18 are respectively concave in the direction away from the hollow screw groove 16, ensuring that the hollow screw 15 moves upward to drive the three arc plates 18 to tighten toward the center of the space it forms, so that the hollow screw 15 moves upward to drive the three arc plates 18 to deform and fix the brush.

[0025] The top of the hollow screw 15 gradually tilts from the outer edge to the inner edge to form a slope, and the bottom of the arc plate 18 is provided with a slope. The slope at the bottom of the arc plate 18 is fixedly matched with the slope at the top of the hollow screw 15 to further ensure that when the hollow screw 15 moves upward, it simultaneously drives the three arc plates 18 to tighten toward the center of the space formed by it.

[0026] A hollow base 17 is fixedly installed between the tops of the three arc-shaped plates 18. The cross section of the hollow base 17 is an I-shaped, and the hollow base 17 is fixedly installed with the lubricating base plate 4. The lubricating base plate 4 is provided with through holes 14 having the same number as the hollow bases 17, and the through holes 14 are connected to the corresponding hollow bases 17.

[0027] On the top of the lubricating bottom plate 4, an inner bottom plate 13 is placed. Through holes are provided on the inner bottom plate 13, and the number of the through holes is the same as that of the through holes 14. The through holes correspond to the through holes 14 one by one. The sponge 10 is placed on the inner bottom plate 13. Three solid rods 11 are fixedly installed on the top of the lubricating bottom plate 4. The solid rods 11 pass upward through the inner bottom plate 13 and are sleeved with hollow sleeve rods 12. The bottom of the hollow sleeve rod 12 is fixedly and cooperatively installed with the inner bottom plate 13. A perforation 8 allowing the hollow sleeve rod 12 to pass through is provided on the push plate 9. When replacing the sponge 10, the hollow sleeve rod 12 is pulled upward. The hollow sleeve rod 12 drives the inner bottom plate 13 to move upward, and the inner bottom plate 13 drives the sponge 10 to move upward, so as to replace the sponge 10.

[0028] A screw sleeve 20 is provided at the top of the second screw cylinder 3. A screw groove 19 is provided at the bottom inside the first screw cylinder 2. The screw groove 19 is threadedly connected with the screw sleeve 20.

[0029] The working principle of a lubricating device for a numerical control lathe provided by the present utility model is as follows:

[0030] During use, first install a new brush. The brush handle of the brush is inserted into the inside of the hollow base 17 through the hollow screw 15. The hollow screw 15 is rotated clockwise to make the hollow screw 15 move upward. The upward movement of the hollow screw 15 drives the three arc-shaped plates 18 to tighten towards the center position of the space forming the clamping space for the brush handle, so as to fix the brush handle of the brush.

[0031] While the hollow screw 15 moves upward, it generates a pressure on the hollow base 17 through the arc-shaped plate 18. The hollow base 17 deforms the lubricating bottom plate 4. The deformation of the lubricating bottom plate 4 exerts a pressure on the inner bottom plate 13. Thus, the inner bottom plate 13 squeezes the sponge 10 upward. Therefore, a small amount of lubricating oil in the sponge 10 quickly infiltrates the new brush along the through holes on the inner bottom plate 13 and the through holes 14 on the lubricating bottom plate 4. Thus, the new brush before lubrication operation is pre-infiltrated to prevent the new brush from directly performing the lubrication operation and causing wear to the parts to be lubricated without being infiltrated with lubricating oil.

[0032] When lubricating the numerical control lathe, the air cylinder 6 is started. The air cylinder 6 drives the air cylinder rod 7 to move downward. The air cylinder rod 7 pushes the push plate 9 to move downward. The perforation 8 on the push plate 9 passes through the hollow sleeve rod 12 and moves downward along the inner wall of the second screw cylinder 3 and contacts the sponge 10 on the inner bottom plate 13. The push plate 9 continues to move downward to squeeze the sponge 10. The lubricating oil inside the sponge 10 passes through the through holes on the inner bottom plate 13 and flows into the hollow base 17 through the through holes 14, so that the lubricating oil continuously wets the brush, facilitating the brush to lubricate the numerical control lathe.

[0033] When the brush is severely worn and needs to be replaced, only need to rotate the hollow screw 15 counterclockwise. By moving downward through the hollow screw 15, the clamping of the brush by the three arc-shaped plates 18 can be released. At this time, take out the brush, and then repeat the above operation to replace the new brush.

[0034] When the sponge 10 needs to be replaced, hold the first screw cylinder 2 with the left hand and turn the second screw cylinder 3 counterclockwise with the right hand, so that the two are separated. At this time, pull the hollow sleeve rod 12 upward. The hollow sleeve rod 12 drives the inner bottom plate 13 to move upward, and the inner bottom plate 13 drives the sponge 10 to move upward as well, so as to replace the sponge 10.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
