Description

Technical Field

[0001] This utility model relates to the field of tool maintenance technology, specifically a tool maintenance mechanism for CNC machine tools. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. The information is input into the CNC device via an information carrier, and after processing, the CNC device sends out various control signals to control the movement of the machine tool's cutting tools. The machine tool automatically processes parts according to the shape and size required by the drawings. However, the large amount of cutting caused by the machine tool will cause certain damage to the cutting tools. Therefore, it is necessary to maintain the cutting tools. To this end, a tool maintenance mechanism for CNC machine tools is proposed.

[0003] A search revealed that prior art, publication number CN221363734U, discloses a tool maintenance mechanism for CNC machine tools, comprising: a housing, a clamping plate, and an oiling mechanism. The oiling mechanism includes a lifting frame, with an oil box fixedly installed inside the lifting frame. An oiling sponge roller is mounted on the top of the lifting frame via a return spring, and an oil-absorbing cotton strip extending into the oil box is fixedly installed at the bottom of the oiling sponge roller. The clamping plate has equidistant clamping holes inside, and a clamp is movably mounted inside the clamping holes. This invention uses the return spring to drive two sets of oiling sponge rollers to elastically return, allowing the oiling sponge rollers to elastically return and adhere to the surfaces of tools of different specifications and irregular tools when oiling them. This ensures that the oiling sponge rollers can oil the surfaces of tools of different specifications and irregular tools, avoiding oiling dead zones and improving the tool oiling and maintenance effect.

[0004] However, the aforementioned patent uses an adjustable clamping tool to clamp and maintain tools of different specifications. But the aforementioned patent uses a hoisting method to install the tool and perform oiling maintenance. In this case, the rotating column drives the tool inside the clamping plate to rotate. Because the clamping device uses a spring-pressed clamping block to fix the tool, the tool in the hoisting method will shake during the rotation, which will cause the tool to collide with the oiling sponge roller during the rotation, causing the oiling sponge roller to break and affecting its use. Therefore, a tool maintenance mechanism for CNC machine tools is proposed. Utility Model Content

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-5 This utility model provides a technical solution:

[0035] A tool maintenance mechanism for CNC machine tools, comprising:

[0036] The base 1 is used to support the maintenance box 2, and the side wall of the base 1 is equipped with a controller 4;

[0037] The clamping mechanism 6 is located inside the curing box 2 and is used to clamp and fix the CNC tool during curing.

[0038] A support and stabilization mechanism 7, located below the clamping mechanism 6, is used to support the tool clamped and fixed inside the clamping mechanism 6; and

[0039] An oiling mechanism 5 is used to oil the tools held inside the clamping mechanism 6. A door 3 is mounted on the exterior of the maintenance box 2 via a hinge.

[0040] By setting the clamping mechanism 6 inside the curing box 2, the CNC fixture is fixed by the clamping mechanism 6, and a support and stabilizing mechanism 7 is set below the clamping mechanism 6 to support the fixed tool. The support and stabilizing mechanism 7 supports the tool clamped and fixed inside the clamping mechanism 6, so as to prevent the tool from shaking when the clamping mechanism 6 is driven to rotate, causing the tool to collide with the oiling sponge roller 28, which would damage the equipment and affect the oiling and curing of the tool.

[0041] The stabilizing mechanism 7 includes:

[0042] Support base 13 is disposed below clamping mechanism 6 via connecting column 15;

[0043] The compression seat 14, which is provided on the inner surface of the support seat 13 by means of a support spring, is used to support the tool inserted inside the clamping mechanism 6.

[0044] The inner bottom surface of the extrusion seat 14 is made of mesh to facilitate the flow of lubricating oil flowing down the surface of the tool through the extrusion seat 14 to the interior of the support seat 13. The bottom surface of the support seat 13 is provided with an oil drain hole, and a removable sealing plug is provided inside it.

[0045] The support base 13 is positioned below the clamping mechanism 6 via the connecting column 15, and the inner surface of the support base 13 is connected to the extrusion seat 14 via a support spring. The inner bottom surface of the extrusion seat 14 is mesh-like. When the tool is inserted into the clamping hole 19 inside the clamping plate 16, the bottom end of the tool presses downward against the extrusion seat 14. After the tool is installed, clamped, and fixed, the tool is in a vertical position. When the clamping plate 16 is driven to rotate the tool, the tool will not shake, ensuring the stability between the tool and the oiling sponge roller 28.

[0046] Clamping mechanism 6 includes:

[0047] The clamping plate 16 is located on the outside of the upright 8 and at the top of the connecting column 15. The clamping plate 16 has clamping holes 19 equidistantly arranged inside. The clamping blocks 20 are movably arranged inside the clamping holes 19. The clamping blocks 20 are connected to the inner wall of the placement grooves 17 equidistantly opened inside the clamping plate 16 through clamping springs 18.

[0048] The outer arc surface of the upright post 8 is provided with a through groove 12. The retaining plate 16 is sleeved on the outside of the upright post 8, and the center thread of the retaining plate 16 is sleeved on the thread of the outer arc surface of the lead screw 9. The top of the upright post 8 is provided with a first servo motor 10 for driving the lead screw 9 to rotate. The bottom end of the upright post 8 passes through the curing box 2 and the base 1 and is keyed to the output shaft of the second servo motor 11 provided inside the base 1, for driving the retaining plate 16 to drive the clamped tool to rotate.

[0049] Furthermore, placement slots 17 are equidistantly provided inside the card plate 16, and each placement slot 17 is provided with a clamping block 20 for clamping the tool. The tool inserted into the clamping hole 19 is squeezed and fixed by the elastic force of the clamping spring 18, thereby clamping and fixing the tool. This allows for clamping of tools of different specifications, increasing the applicability of this utility model.

[0050] Furthermore, the lead screw 9 is rotatably mounted inside the upright 8. The first servo motor 10 and the second servo motor 11 are model MSMF012L1U2M, which can be purchased online according to actual use. They are not within the scope of protection of this application. The first servo motor 10 drives the lead screw 9 to rotate, causing the retaining plate 16, which is threaded onto the outside of the lead screw 9, to rise and fall. The position of the retaining plate 16 is adjusted to maintain tools of different lengths.

[0051] Oiling mechanism 5 includes:

[0052] The grooves 21 are symmetrically opened on the inner walls of both sides of the curing box 2, and a partition is provided in the middle of the grooves 21.

[0053] The lifting rod 22 is provided on both sides of the inner partition of the groove 21, and the working end of the lifting rod 22 is provided with a lifting block 23, which is slidably disposed inside the groove 21;

[0054] The telescopic rod 24, which is set on the side wall of the lifting block 23, is used to drive the oiling sponge roller 28 set inside the bracket 26 to extend and retract.

[0055] An oil box 25 is provided on the side opposite to the oiling sponge roller 28 of the bracket 26, which absorbs the lubricating oil inside to the inside of the oiling sponge roller 28 through the oil-absorbing cotton strip 27.

[0056] Finally, an oiling mechanism 5 is also installed inside the maintenance box 2, which can be adjusted according to the height of the clamping plate 16. The lifting block 23 is driven to rise and fall by the lifting rod 22, which in turn drives the bracket 26 at the working end of the telescopic rod 24 on the side wall of the lifting block 23 to rise and fall. The oiling sponge roller 28 is connected to the oil box 25 through the oil-absorbing cotton strip 27. The oil-absorbing cotton strip 27 absorbs the lubricating oil inside the oil box 25 into the oiling sponge roller 28, and then the oiling sponge roller 28, which is set to rotate at the front end of the drive bracket 26, applies oil to the tool inserted into the clamping plate 16, thereby achieving oiling and maintenance of the tool.

[0057] Working principle: When CNC tools need to be maintained, open the box door 3 and insert the tools into the clamping holes 19 on the surface of the clamping plate 16. When the tools are inserted into the clamping holes 19, the bottom end presses against the pressing seat 14 connected by the support spring inside the support seat 13. After pressing, the clamping block 20 connected by the clamping spring 18 inside the clamping plate 16 clamps and fixes the tools.

[0058] After the tool is fixed, the working end of the lifting rod 22 is extended by the controller 4. The controller 4 is model XD2-16R-E, and the lifting rod 22 and telescopic rod 24 are model TGA-500-10-12V. They can be purchased online according to actual needs and are not within the scope of protection of this application. The position of the lifting block 23 is adjusted to ensure that when the working end of the telescopic rod 24 is extended, the oiling sponge roller 28 is in contact with the side wall of the fixed tool. The second servo motor 11 drives the upright rod 8 to rotate, which drives the clamping plate 16 to rotate. When the tool rotates, it squeezes the oiling sponge roller 28, and the lubricating oil inside the oiling sponge roller 28 adheres to the surface of the tool, thus achieving the need for tool maintenance.

[0059] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
