Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of numerical control machine tools, in particular to a Y-axis movement compression-resistant side wall seat and a numerical control machine tool. BACKGROUND

[0002] The Y-axis movement compression-resistant side wall seat is a basic structure for supporting the gantry of the numerical control machine tool and components such as the electric spindle on the gantry. The compression resistance of the side wall seat mainly depends on the material strength, spatial structure and loss of the relative movement structure (slide rail). The material strength and spatial structure of the side wall seat have been very mature, and have quite strong compression resistance. The Y-axis movement of the gantry on the slide rail of the side wall seat has a great compression test on the side wall seat. At present, the commonly used method is to reduce the friction resistance between the slide of the gantry and the slide rail of the side wall seat to improve the compression resistance of the side wall seat to the Y-axis movement. In addition to the material selection of the slide rail and the slide, lubrication between the two is also necessary. Reducing wear is a manifestation of improving the compression resistance of the side wall seat to the Y-axis movement, and can also improve the precision of the Y-axis movement of the gantry, that is, improve the machining precision of the numerical control machine tool.

[0003] At present, the common lubrication method between the slide rail and the slide is to directly spray lubricating oil on the surface of the slide rail, such as the patent with the announcement number CN217096599U. Another method is to fill lubricating grease in the blind hole on the surface of the slide rail, and the slide contacts the lubricating grease to achieve the purpose of lubrication. The former has a large weight of the gantry, which causes the slide to closely fit with the slide rail. The lubricating oil directly added on the surface of the slide rail is difficult to enter between the slide and the slide rail, resulting in large loss of lubricating oil and frequent replenishment of lubricating oil. The latter is sufficient in the early stage of lubrication, but after a period of operation, the lubricating grease is consumed, resulting in insufficient lubrication, and the lubricating grease needs to be replenished frequently and in time. SUMMARY

[0004] The purpose of the present application is to provide a Y-axis movement compression-resistant side wall seat and a numerical control machine tool to solve the above-mentioned deficiencies in the prior art.

[0007] Further, the protrusion is a rolling ball rollingly arranged on the inner wall of the sliding ring and rollingly matched with the corresponding helical groove.

[0013] The application further provides a numerical control machine tool comprising two Y-axis movement pressure-resistant side wall seats arranged side by side, and the two ends of the portal frame are slidably arranged on the seat bodies of the two Y-axis movement pressure-resistant side wall seats.

[0015] Since the Y-axis movement pressure-resistant side wall seat has the above-mentioned effects, the numerical control machine tool containing the Y-axis movement pressure-resistant side wall seat should also have corresponding effects. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0026] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

A vertical counterbore hole 3 is arranged on each slide rail 2 and spaced apart along the length direction. The slide rail 2 is screwed on the seat body 1 through the bolts 4 sunk in the counterbore holes 3. The gantry 6 is slidably connected to the seat body 1 through the sliding seat 5 at the bottom of the gantry 6 and the slide rail 2. A plurality of lubricating units 7 corresponding to the counterbore holes 3 are arranged on each slide rail 2 and spaced apart along the length direction. The lubricating unit 7 is assembled so as to extrude and apply the lubricant 7.10 filled in the counterbore hole 3 to the bottom of the sliding seat 5 when the sliding seat 5 slides to the corresponding counterbore hole 3.

[0028] In the above technical solution, the Y-axis movement pressure-resistant side wall seat provided by the present application directly fills the lubricant 7.10 into the counterbore hole 3 for mounting the bolt 4. The lubricating unit 7 is arranged at each counterbore hole 3. When the sliding seat 5 of the gantry 6 slides to the corresponding counterbore hole 3, the lubricating unit 7 applies pressure to the lubricant 7.10 filled in the counterbore hole 3 to extrude and apply the lubricant 7.10 to the bottom of the sliding seat 5, thereby realizing the lubricating effect between the sliding seat 5 and the slide rail 2. When the sliding seat 5 slides away from the counterbore hole 3, the pressure of the lubricating unit 7 on the lubricant 7.10 is removed, and the remaining lubricant 7.10 is retained in the counterbore hole 3, thereby realizing the automatic and timely extrusion of the lubricant 7.10 in a long time span, and the lubricant 7.10 in the counterbore hole 3 does not need to be frequently supplemented.

[0029] As a preferred technical scheme of the present application, the lubricating unit 7 comprises a piston 7.1, a columnar rod 7.2, an abutting wheel 7.4, a cam 7.5, a sliding ring 7.6 and an elastic member 7.8, wherein the piston 7.1 is slidingly connected in the length direction of the countersunk hole 3 in the countersunk hole 3, and the lubricant 7.10 is filled in the countersunk hole 3 above the piston 7.1. The columnar rod 7.2 is rotationally connected to the side of the slide rail 2 and penetrates the side wall of the countersunk hole 3, and two helical grooves 7.3 are arranged on the circumferential surface of the columnar rod 7.2, the two helical grooves 7.3 are opposite in rotation direction and are connected in communication at one end opposite to each other.

Specifically, the abutting portion is in the shape of an ellipse as a whole, and the elastic convex arc portions 7.41 are made of a material having a rebounding performance, such as rubber. The cam 7.5 is coaxially fixedly connected to the other end of the columnar rod 7.2, when the two elastic convex arc portions 7.41 of the abutting wheel 7.4 do not abut against the piston 7.1, the convex portion of the cam 7.5 is upwardly located on the moving path of the gantry 6; further, the gantry 6 is provided with a let-in groove 7.9 corresponding to the cam 7.5 on the bottom of the front and back sides of the gantry 6 in the sliding direction of the slide rail 2, before the sliding seat 5 completely covers the corresponding countersunk hole 3, the convex portion of the cam 7.5 enters the let-in groove 7.9, and the cam 7.5 cannot be forced to rotate, when the sliding seat 5 completely covers the corresponding countersunk hole 3, the cam 7.5 reaches the end of the let-in groove 7.9 and abuts against the sliding seat 5 (the end wall of the let-in groove 7.9), so that the cam 7.5 starts to rotate, ensuring that the lubricant 7.10 cannot be squeezed out of the countersunk hole 3 before being completely covered by the sliding seat 5, thereby causing excessive loss of the lubricant 7.10. The sliding ring 7.6 is slidingly sleeved on the columnar rod 7.2, specifically, a sliding groove is formed in the seat body 1, a sliding block is fixedly connected to the sliding ring 7.6, and the sliding ring 7.6 is slidingly connected to the seat body 1 in a sliding block and sliding groove cooperation manner, the sliding ring 7.6 is slidingly connected to the seat body 1 in the length direction of the columnar rod 7.2, a protrusion 7.7 is arranged on the inner wall of the sliding ring 7.6, and the protrusion 7.7 is movably arranged in the helical groove 7.3. Specifically, the protrusion 7.7 is fixedly connected to the inner wall of the sliding ring 7.6, and the protrusion 7.7 is in sliding cooperation with the helical groove 7.3; preferably, the protrusion 7.7 is a rolling ball, the rolling ball is rollingly embedded on the inner wall of the sliding ring 7.6, and the rolling ball is in rolling cooperation with the corresponding helical groove 7.3.The process of restoring the deformation of the elastic member 7.8 drives the protrusion 7.7 on the sliding ring 7.6 to move to the place where the two spiral grooves 7.3 are connected; preferably, the two spiral grooves 7.3 are connected at the end close to the cam 7.5, the elastic member 7.8 is a compression spring, the compression spring is sleeved on the columnar rod 7.2, one end of the compression spring is in abutment with the sliding rail 2, and the other end is in abutment with the sliding ring 7.6; alternatively, the two spiral grooves 7.3 are connected at the end away from the cam 7.5, the elastic member 7.8 is a compression spring, the compression spring is sleeved on the columnar rod 7.2, one end of the compression spring is in abutment with the cam 7.5, and the other end is in abutment with the sliding ring 7.6. Specifically, the counterbore 3 comprises a first hole section 3.1 and a second hole section 3.2 connected in sequence from top to bottom, the diameter of the first hole section 3.1 is larger than that of the second hole section 3.2, the screw rod of the bolt 4 passes through the second hole section 3.2 and is screwed to the seat body 1, the nut of the bolt 4 is in abutment with the bottom of the first hole section 3.1, and the bolt 4 and the abutment wheel 7.4 are both located in the first hole section 3.1.

[0030] In the above technical solution, for the lubricating unit 7 at the position of the slide rail 2 where the slide 5 of the gantry 6 does not slide, the elastic force of the elastic member 7.8 makes the protrusion 7.7 on the sliding ring 7.6 located at the position where the two spiral grooves 7.3 are connected, the convex part of the cam 7.5 faces upward, the convex part is located in the sliding path of the slide 5 of the gantry 6, and the two elastic convex arcs 7.41 of the abutting wheel 7.4 do not abut against the piston 7.1, at this time, the abutting wheel 7.4 does not exert upward force on the piston 7.1, and the lubricant 7.10 is located in the counterbore 3 above the piston 7.1; when the slide 5 of the gantry 6 slides in the first direction to a certain counterbore 3, before the slide 5 completely covers the counterbore 3, the convex part of the cam 7.5 enters the relief groove 7.9 on the front side of the forward direction of the gantry 6, the cam 7.5 cannot be forced to rotate, the extrusion wheel cannot exert extrusion force on the piston 7.1, and the lubricant 7.10 cannot be squeezed out of the counterbore 3 in advance to cause excessive loss; when the slide 5 completely covers the corresponding counterbore 3, the convex part of the cam 7.5 reaches the end of the relief groove 7.9 and abuts against the slide 5 (the end wall of the relief groove 7.9), so that the cam 7.5 starts to rotate in the positive direction, the cam 7.5 drives the column 7.2 to rotate, on one hand, the column 7.2 rotates relative to the sliding ring 7.6 and the protrusion 7.7, one of the spiral grooves 7.3 on the column 7.2 cooperates with the protrusion 7.7 to make the sliding ring 7.6 move relative to the axial direction of the column 7.2, so that the elastic member 7.8 is elastically deformed to store energy, on the other hand, the cam 7.5 drives the abutting wheel 7.4 to rotate through the column 7.2, the elastic convex arc 7.41 of the abutting wheel 7.4 starts to abut against the piston 7.1, the piston 7.1 squeezes the lubricant 7.10 above to the bottom surface of the slide 5, and because the lubricant 7.10 is blocked by the slide 5 and the lubricant 7.10 itself cannot be compressed, as the extrusion force between the elastic convex arc 7.41 of the abutting wheel 7.4 and the piston 7.1 becomes larger and larger, the elastic convex arc 7.41 is extruded and deformed to offset the excessive extrusion on the piston 7.1; when the slide 5 slides away and partially exposes the counterbore 3, the convex part of the cam 7.5 enters the relief groove 7.9 on the rear side of the forward direction of the gantry 6, the convex part of the cam 7.5 is released from the extrusion limitation of the bottom of the gantry 6, the elastic force of the elastic member 7.8 is released at this time, so that the sliding ring 7.6 reversely slides and resets relative to the slide rod, the protrusion 7.7 on the sliding ring 7.6 moves to the position where the two spiral grooves 7.3 are connected in the corresponding spiral groove 7.3, so that the column 7.2 reversely rotates, the column 7.2 drives the cam 7.5 and the abutting wheel 7.4 to reversely rotate and reset, the elastic convex arc 7.41 of the abutting wheel 7.4 withdraws the extrusion on the piston 7.1, so that the lubricant 7.10 cannot be squeezed out of the counterbore 3 after the counterbore 3 starts to expose the slide 5, and the excessive loss of the lubricant 7.10 is avoided, at the same time, the deformation of the elastic convex arc 7.41 is restored, then the slide 5 completely slides away from the counterbore 3, and when the slide 5 reaches the next counterbore 3, the lubrication process described above is repeated.

[0031] When the gantry 6 slides in the opposite direction of the first direction, the slide 5 can make the corresponding cam 7.5 of the lubricating unit 7 covered by the counterbore 3 first reverse, drive the column 7.2 to reverse, on the one hand, the other helical groove 7.3 on the column 7.2 and the protrusion 7.7 on the sliding ring 7.6 move together, also make the sliding ring 7.6 move to make the elastic member 7.8 elastically deformed to store energy, on the other hand, the column 7.2 drives the extrusion wheel to reverse, the other elastic convex arc part 7.41 of the extrusion wheel and the piston 7.1 extrusion fit to extrude the lubricant 7.10 to the bottom surface of the slide 5, and after the slide 5 slides away from the counterbore 3 and withdraws from the extrusion of the convex part of the cam 7.5, the elastic force of the elastic member 7.8 is released to reset the slide rod, the protrusion 7.7 on the sliding ring 7.6 moves in the corresponding helical groove 7.3 to make the column 7.2 rotate, the column 7.2 drives the cam 7.5 and the extrusion wheel to rotate to reset. That is, no matter which direction the gantry 6 slides on the slide rail 2, the lubricating unit 7 can be normally triggered. It should be noted that the above-mentioned forward rotation and reverse rotation do not correspond to the clockwise direction of rotation, but only represent the opposite direction of rotation.

[0032] The present application also provides a numerical control machine tool, comprising two parallelly arranged Y-axis movement pressure-resistant side wall seats, both ends of the gantry 6 are simultaneously slidably arranged on the seat body 1 of the two Y-axis movement pressure-resistant side wall seats, and the numerical control machine tool using the Y-axis movement pressure-resistant side wall seat is protected by the present application.

[0033] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
