Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of numerical control lathe, in particular to a slant bed numerical control lathe with high operation stability. BACKGROUND

[0002] The slant bed numerical control lathe is a highly automated metal cutting machine tool, which is mainly used for machining various rotary parts, such as shafts, discs, sleeves and other parts. Due to its precision in machining, it is widely used in mechanical manufacturing, automobiles, aerospace, electronics and many other fields. Compared with traditional flat bed lathes, slant bed numerical control lathes have many advantages, of which the most obvious advantage is that due to its inclined structure, the generated chips are not easy to remain in the guide rail during turning, and the chips will naturally slide down the bed slope under the action of gravity, thereby reducing the wear of the guide rail and improving the service life and machining accuracy of the machine tool.

[0003] The slant bed numerical control lathe mainly consists of a bed, a clamping assembly, a tail tower assembly, a tool tower assembly, a multi-directional moving assembly and a numerical control system, etc. The clamping assembly and the tail tower assembly are located directly above the chip removal port of the bed, and the tool tower assembly and the multi-directional moving assembly are in an inclined state on the side. When the clamping assembly clamps the workpiece and rotates at high speed, the tail tower assembly will be tightly pressed against the other end of the workpiece according to the length of the workpiece, thereby enhancing the stability of the workpiece fixation. The tool tower assembly will be driven by the multi-directional moving assembly to perform complex and precise machining on the workpiece. The multi-directional moving assembly drives the tool tower assembly to move in the Z-axis, X-axis and Y-axis directions, thereby making the tool tower assembly more flexible and the workpiece more precise.

[0004] However, in order to prevent thermal deformation of the workpiece during machining, cold water or coolant is sprayed at the machining site for cooling. At this time, once the combination of chips and liquid splashes onto the bed slope, due to the viscosity and surface tension of the liquid, they will quickly adhere to the lathe and are not easy to naturally slide down. Currently, the slant bed numerical control lathe is equipped with telescopic inclined plates on the surface of each axial guide rail. On the one hand, the telescopic inclined plates can effectively reduce the splashing of chips into the guide rail; on the other hand, as the telescopic inclined plates continuously extend and retract, the part of the chips adhered to the surface of the telescopic inclined plates will be scraped off by the extrusion action between the telescopic inclined plates, so that the surface of the telescopic inclined plates is relatively clean and tidy.

[0005] However, it is inevitable that the high and low difference between the plates will exist in order to complete the telescopic operation, which will cause the upper layer plate to push the debris on the surface of the lower layer plate together, and due to the viscosity and surface tension of the liquid on the surface of the debris, part of the debris will be attached to the surface of the lower layer plate in a linear shape after being pushed by the upper layer plate (this situation often occurs on the telescopic inclined plate in the Z-axis direction due to the transverse telescopic design of the telescopic inclined plate in the Z-axis direction), and long-term accumulation will cause the adhesion layer to become thicker and more firmly adhered, and the later cleaning is very laborious, and too much debris will even seriously affect the stability and precision of the tool turret assembly operation. Although the hard scraper used to clean the debris can remove most of the attached debris, the hard scraper is difficult to adapt to the high and low difference between the plate joints, so that the telescopic inclined plate located in the lower layer is blocked by the upper telescopic inclined plate and cannot fully contact the hard scraper, and the surface of the lower telescopic inclined plate still has debris, and the position of the tool turret assembly after each machining is different, that is, the length of the telescopic inclined plate is not fixed each time, and the hard scraper with fixed size is difficult to adapt to such changes, resulting in unsatisfactory scraping effect.

[0006] In view of the above problems, it is urgent to make innovative design on the basis of the original operation stable inclined bed body numerical control lathe. SUMMARY

[0009] Preferably, the hanging rail is hung in the numerical control case in a suspended manner through a hanging rod; The hanging rail is parallel to the telescopic inclined plate. The length of the hanging rail is greater than twice the length of the telescopic inclined plate.

[0010] Preferably, the top end of the material placing table is provided with an inner groove. The upper surfaces of the inner groove and the material receiving plate are covered with sponge soft pads. One end of the inner groove is provided in an inclined manner close to the inside of the numerical control case.

[0011] Preferably, a fixed plate is fixed between the upper ends of the first and second sliding plates. A return tension spring is connected between one end of the fixed plate and the inner wall of the numerical control case through an iron ring. The distance between the first and second sliding plates is greater than the length of the telescopic inclined plate.

[0012] Preferably, the scraping assembly further comprises a control spring fixed at one end of the elastic water hose and one side of the lower end of the first sliding plate. One side of the telescopic inclined plate is fixed with a limiting piece. The limiting piece is composed of an arc-shaped auxiliary plate and a round rod located at the center position of the arc-shaped auxiliary plate. One end of the elastic water hose is bent along the inner arc track of the arc-shaped auxiliary plate and passes around the round rod.

[0013] Preferably, the inner walls of the elastic water hose are uniformly provided with a plurality of groups of shaped steel wires. The plurality of groups of shaped steel wires are coaxially distributed on the inner wall half of the elastic water hose. The length of the shaped steel wire is consistent with the length of the elastic water hose.

[0014] Preferably, the material receiving assembly further comprises a second sliding block fixed on both sides of the material receiving plate. The second sliding block is composed of a rectangular plate and a sliding column fixed at one end of the rectangular plate. The other end of the rectangular plate is fixedly connected with the side edge of the material receiving plate.

[0015] Preferably, the bottom end of the second sliding plate is fixed with a moving plate. The lower end of the material receiving plate and the top end of the moving plate are rotationally connected through a shaft column. The other side of the moving plate is fixed with a first sliding block.

[0016] Preferably, one side of the suspension rail is provided with two groups of sliding grooves. One group of the sliding grooves is matched with the first sliding block.

[0017] Preferably, a side rail groove is formed on one side of the inner wall of the numerical control case. The side rail groove is parallel to the telescopic inclined plate. The size of the side rail groove is adapted to the size of the slide post in the second sliding block.

[0018] Compared with the prior art, the present application has the following advantages: 1.

Compared with the traditional hard scraper, the flexible elastic water belt has strong self-adaptability and ideal adhesion effect with the telescopic inclined plate, effectively reducing the accumulation of scrap on the surface of the lower plate and enhancing the stability and travel accuracy of the equipment during operation. In addition, the cooperation of the position control spring and the limiting piece can make the extension length of the elastic water belt adapt to the extension length of the telescopic inclined plate each time, no matter where the telescopic inclined plate stays each time, the elastic water belt can cover the telescopic inclined plate transversely, compared with the traditional hard scraper with fixed size, the length of the elastic water belt can be self-adapted, which can effectively reduce the contact gap between the elastic water belt and the telescopic inclined plate, and make the scraping effect of the adhering scrap more ideal.

[0019] 2. The present application uses the weight of the workpiece to press the receiving plate, so that the second sliding plate slides along the hanging rail, and the second sliding block slides along the other group of sliding slots in the side rail groove and the suspension rail, the second sliding block is affected by the change of the track of the other group of sliding slots in the side rail groove and the suspension rail, and rotates to drive the receiving plate to rotate, and places the workpiece on the placing table.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0032] Please refer to Figures 1 to 10 The present application provides a technical solution: a slant bed numerical control lathe with high operation stability, which comprises a numerical control machine box 1, an object placing table 4 fixed on the front of the numerical control machine box 1, and a telescopic slant plate movably arranged in the numerical control machine box 1, and further comprises: a hanging rail 2 fixed on the upper end of the numerical control machine box 1; a scraping assembly driven by the weight of a workpiece to adaptively extend the height difference and extension width of the telescopic slant plate; a material receiving assembly with flexible feeding function driven by the weight of a workpiece; In a specific implementation, the numerical control machine box 1 is composed of a bed, a clamping assembly, a tail tower assembly, a tool tower assembly, a multi-directional movement assembly, and a numerical control system, and the layout and electrical connection relationship of each assembly are consistent with the prior art, and the present application will not be described in detail. In addition, the "Z-axis direction", "X-axis direction" and "Y-axis direction" mentioned in the present application are also consistent with the axis direction of the prior art. In addition, it should be noted that the present application is commonly used to process regular solid shafts, discs and other workpieces. Such parts are heavy, and the part to be turned often has a large amount of waste, and the finished workpiece still has a heavy weight. The present application uses the weight of the workpiece to complete the flexible feeding and scraping of the waste.

[0033] The scraping assembly includes a first sliding plate 6 slidingly arranged at the top end of the hanging rail 2 and an elastic water belt 5 fixed to the lower end of the first sliding plate 6 and expanding the surface by internal interference to fully adhere to the telescopic inclined plate. In a specific implementation, the elastic water belt 5 is made of PU material, which has high strength and tear resistance, and is not easy to be damaged by scraping with waste, and is elastic. The water injected into the elastic water belt 5 is in an interference state, which ensures that the elastic water belt 5 is in an expanded state, so that the elastic water belt 5 can fully adhere to the surface of the telescopic inclined plate.

[0034] The receiving assembly includes a second sliding plate 8 slidingly arranged at the top end of the hanging rail 2, a receiving plate 12 movably arranged above the chip removal port of the numerical control machine box 1, and a suspension rail 3 fixed to the inner wall of the numerical control machine box 1 and rotating the receiving plate 12 by adaptively changing the track.

[0035] In a specific implementation, in the initial state, that is, the state where the receiving plate 12 is not affected by the weight of the workpiece, the receiving plate 12 should be located below the clamping assembly, ready to receive the cut workpiece falling onto the receiving plate 12. As shown in Figure 9 and Figure 10 It can be clearly seen from the drawings that the upper end of the receiving plate 12 is designed as an arc plate, which can effectively reduce the risk of rolling of the workpiece after falling on the receiving plate 12, and the workpiece can also roll down more smoothly along the arc surface of the arc plate of the receiving plate 12 when the receiving plate 12 is rotated to dump the material later.

[0036] The hanging rail 2 is suspended in the numerical control machine box 1 by the hanging rod; In a specific implementation, the hanging design of the hanging rail 2 can prevent the first sliding plate 6 and the second sliding plate 8 from colliding with the clamping assembly in the numerical control machine box 1 when sliding.

[0037] The hanging rail 2 is parallel to the telescopic inclined plate; In practice, when the first slide plate 6 and the second slide plate 8 slide along the track of the hanging rail 2, it can be ensured that the movement trajectory of the elastic water belt 5 and the receiving plate 12 can conform to the telescopic inclined plate, especially the elastic water belt 5 can always remain in contact with the surface of the telescopic inclined plate.

[0038] The length of the hanging rail 2 is more than twice the length of the telescopic inclined plate.

[0039] In practice, the first slide plate 6 and the second slide plate 8 slide together inside the same set of hanging rails 2, which ensures that when the elastic water hose 5 slides to the end of the telescopic ramp, the second slide plate 8 will not detach from the hanging rails 2.

[0040] The top of the shelf 4 has an inner groove; In specific implementation, as shown in the appendix Figure 3 As shown, when the receiving plate 12 is rotating and pouring material, it is flush with the top surface of the shaping wire 14, so that the workpiece can slide smoothly into the inner groove.

[0041] The inner groove and the upper surface of the receiving plate 12 are both covered with sponge pads; In practice, the sponge pad prevents the workpiece from being damaged by excessive impact when it falls onto the receiving plate 12 and into the inner groove.

[0042] One end of the inner groove is inclined near the inside of the CNC machine housing 1.

[0043] In practice, when the workpiece enters the inner groove, it tends to slide automatically into the groove due to the influence of its inclined surface, which prevents the workpiece from rebounding and falling off due to the rebound force.

[0044] A fixing plate 9 is fixed between the upper ends of skateboard number 1 (6) and skateboard number 2 (8); In practice, the fixing plate 9 fixes the first slide plate 6 and the second slide plate 8 together, so that the receiving plate 12 can drive the first slide plate 6 and the second slide plate 8 to slide along the inner rail 2 at the same time while being moved by the weight of the workpiece.

[0045] A reset spring 13 is connected between one end of the fixed plate 9 and the inner wall of the CNC machine housing 1 by an iron ring; In practice, when the fixed plate 9 moves diagonally downward, the reset spring 13 can be stretched. After the workpiece is unloaded, the fixed plate 9 can be automatically returned to its original position by the rebound of the reset spring 13, preparing for the next material receiving. It should be noted that a square groove with sufficient space should be provided inside the CNC machine housing 1 at the position corresponding to the reset spring 13, so that the reset spring 13 will not rub unnecessarily against the CNC machine housing 1 when it is stretched.

[0046] The distance between skateboard number 6 and skateboard number 8 is greater than the length of the telescopic ramp.

[0047] In specific implementation, the sufficient space distance between the first sliding plate 6 and the second sliding plate 8 does not hinder the operation of the whole device.

[0048] The scraping assembly further comprises a control spring 7 fixed at one end of the elastic hose 5 and one side of the lower end of the first sliding plate 6. In specific implementation, the control spring 7 provides power for the rebound of one end of the elastic hose 5, so that the extension length of the elastic hose 5 can be shortened more easily.

[0049] The telescopic inclined plate is fixed on one side of a limiting piece 10; The limiting piece 10 is composed of an arc-shaped auxiliary plate and a round rod located at the center of the arc-shaped auxiliary plate; In specific implementation, it is necessary to point out that in the prior art, one end of the X-axis telescopic inclined plate is fixed on one of the plates in the Z-axis telescopic inclined plate, and the tool turret assembly is fixed on the surface of the X-axis telescopic inclined plate, so that the tool turret assembly can move along the X-axis, and the X-axis telescopic inclined plate can move along with the Z-axis telescopic inclined plate, so that the tool turret assembly can also move along the Z-axis. On this premise, one end of the limiting piece 10 is fixed on the surface of the same plate in the Z-axis telescopic inclined plate as one end of the X-axis telescopic inclined plate, so that the limiting piece 10 cannot move along the X-axis, but can move along the Z-axis.

[0050] One end of the elastic hose 5 is bent along the inner arc track of the arc-shaped auxiliary plate and passes around the round rod.

[0051] In specific implementation, the surfaces of the arc-shaped auxiliary plate and the round rod are polished and polished, so that the friction between the elastic hose 5 and the limiting piece 10 is small when bending, and the elastic hose 5 can be bent more easily.

[0052] The inner wall of the elastic hose 5 is uniformly provided with a plurality of groups of shaping steel wires 14; The plurality of groups of shaping steel wires 14 are coaxially arranged on one half of the inner wall of the elastic hose 5; The length of the shaping steel wire 14 is consistent with the length of the elastic hose 5.

[0053] In specific implementation, the shaping steel wire 14 provides a certain supporting force for the elastic hose 5, so that the half side of the elastic hose 5 not in contact with the telescopic inclined plate will not be excessively expanded. The addition of the shaping steel wire 14 makes the elastic hose 5 not lack the extrusion force on the telescopic inclined plate because the whole is too soft. The other half side of the elastic hose 5 remains in an expanded state and is tightly attached to the surface of the telescopic inclined plate.

[0054] The material receiving assembly further comprises a second sliding block 16 fixed on both sides of the material receiving plate 12; The second sliding block 16 is composed of a rectangular plate and a sliding column fixed at one end of the rectangular plate; The other end of the oblong plate is fixedly connected with the side edge of the receiving plate 12.

[0055] In the specific implementation, as shown in Figs. 1 and 2, the second sliding block 16 and the receiving plate 12 form an obvious angle, and when the second sliding block 16 slides along the other set of sliding grooves in the suspension rail 3 and the side rail groove 17, the second sliding block 16 is pulled obliquely upward when the trajectories of the two change, so that the receiving plate 12 is passively rotated to achieve the unloading operation. Figure 9 and Figs. 1 and 2, the second sliding block 16 and the receiving plate 12 form an obvious angle, and when the second sliding block 16 slides along the other set of sliding grooves in the suspension rail 3 and the side rail groove 17, the second sliding block 16 is pulled obliquely upward when the trajectories of the two change, so that the receiving plate 12 is passively rotated to achieve the unloading operation. Figure 10 In the specific implementation, as shown in Figs. 1 and 2, the second sliding block 16 and the receiving plate 12 form an obvious angle, and when the second sliding block 16 slides along the other set of sliding grooves in the suspension rail 3 and the side rail groove 17, the second sliding block 16 is pulled obliquely upward when the trajectories of the two change, so that the receiving plate 12 is passively rotated to achieve the unloading operation.

[0056] The bottom end of the second sliding plate 8 is fixedly connected with the moving plate 11. The lower end of the receiving plate 12 and the top end of the moving plate 11 are rotationally connected through a shaft column. In the specific implementation, the receiving plate 12 can be rotated alone, and the moving plate 11 is not affected thereby.

[0057] The other side of the moving plate 11 is fixedly connected with the first sliding block 15.

[0058] The suspension rail 3 is provided with two sets of sliding grooves on one side. One set of the sliding grooves is matched with the first sliding block 15. One set of the sliding grooves is parallel to the telescopic inclined plate. In the specific implementation, the first sliding block 15 slides along one set of the sliding grooves, and the sizes of the two are matched, so that the moving plate 11 moves along the predetermined trajectory, and the moving direction of the moving plate 11 is consistent with the moving direction of the elastic water belt 5, and the overall trajectory operation mode is more in line with the requirements.

[0059] The other set of the sliding grooves is matched with the sliding column in the second sliding block 16. In the specific implementation, the sliding column slides in the other set of the sliding grooves, and the sizes of the two are matched.

[0060] One end of the other set of the sliding grooves is parallel to the telescopic inclined plate, and the other end of the other set of the sliding grooves is in an obliquely upward bent state.

[0061] In the specific implementation, as shown in Figs. 1 and 2, when the second sliding block 16 slides along the section of the sliding groove away from the placement table 4, the opening of the receiving plate 12 can remain in a vertically upward state, and the workpieces in the receiving plate 12 are not easy to fall, and when the second sliding block 16 encounters the section of the sliding groove close to the placement table 4, the second sliding block 16 is passively rotated by the obliquely upward pulling of the section of the sliding groove, so as to achieve the rotating and unloading operation of the receiving plate 12. Figure 2 and Figs. 1 and 2, when the second sliding block 16 slides along the section of the sliding groove away from the placement table 4, the opening of the receiving plate 12 can remain in a vertically upward state, and the workpieces in the receiving plate 12 are not easy to fall, and when the second sliding block 16 encounters the section of the sliding groove close to the placement table 4, the second sliding block 16 is passively rotated by the obliquely upward pulling of the section of the sliding groove, so as to achieve the rotating and unloading operation of the receiving plate 12. Figure 3 In the specific implementation, as shown in Figs. 1 and 2, when the second sliding block 16 slides along the section of the sliding groove away from the placement table 4, the opening of the receiving plate 12 can remain in a vertically upward state, and the workpieces in the receiving plate 12 are not easy to fall, and when the second sliding block 16 encounters the section of the sliding groove close to the placement table 4, the second sliding block 16 is passively rotated by the obliquely upward pulling of the section of the sliding groove, so as to achieve the rotating and unloading operation of the receiving plate 12.

[0062] The inner wall of the numerical control machine box 1 is provided with a side rail groove 17 on one side. The side rail groove 17 is parallel to the telescopic inclined plate. The size of the side rail groove 17 is matched with the size of the sliding column in the second sliding block 16.

[0063] In a specific implementation, the design of the side rail groove 17 enables the slide post in the other set of the second slide block 16 to slide along the inside thereof, thereby increasing the stability of the two ends of the receiving plate 12 when moving, and the track change of the side rail groove 17 is completely consistent with that of the other set of the slide groove in the suspension rail 3.

[0064] Working principle: when using the inclined bed numerical control lathe with high stability, first, the mains electricity is connected to the overall device to power on, and the workpiece is processed, the specific operation and programming method are consistent with the existing mature technology, and the present application will not be elaborated here. During the processing, the position of the tool tower changes constantly, the limiting piece 10 moves with the connecting plate between the X-axis and the Y-axis, that is, the connecting plate drives the limiting piece 10 and the moving direction of the telescopic inclined plate is consistent, when the distance between the tool tower and the clamping assembly is farther, the limiting piece 10 pulls the elastic water belt 5, the extension length of the elastic water belt 5 increases, and the control spring 7 is stretched, when the distance between the tool tower and the clamping assembly is closer, under the rebound of the control spring 7 and the pushing action of the limiting piece 10, the extension length of the elastic water belt 5 decreases, and one side of the elastic water belt 5 always keeps close to the surface of the telescopic inclined plate, and due to the expansion state of the elastic water belt 5, the elastic water belt 5 is tightly attached to the upper plate and the lower plate in the telescopic inclined plate, the workpiece is cut off by the tool after processing, or is pushed out of the clamping assembly by the ejector, after the workpiece falls onto the receiving plate 12, the receiving plate 12 is passively moved downward under the influence of the weight of the workpiece, the two sets of the second slide block 16 drive the moving plate 11 to slide along the inside of the other set of the slide groove in the suspension rail 3 and the side rail groove 17, at the same time, the first slide block 15 slides along the inside of one set of the slide groove in the suspension rail 3, the second slide plate 8 slides along the inside of the suspension rail 2, the second slide plate 8 pulls the first slide plate 6 through the fixed plate 9, so that the first slide plate 6 synchronously slides along the inside of the suspension rail 2, the reset tension spring 13 is stretched, the first slide plate 6 drives the elastic water belt 5 to move along the surface of the telescopic inclined plate, and the waste attached to the surface of the inclined plate is pushed to the chip pocket, and the receiving plate 12 containing the workpiece is close to the placement table 4, the slide posts in the two sets of the second slide block 16 are simultaneously affected by the track change of the side rail groove 17 and the other set of the slide groove in the suspension rail 3, and suddenly move to the oblique upper side, at the same time, the moving track of the moving plate 11 does not change, so that the second slide block 16 drives the receiving plate 12 to rotate, so that the workpiece in the receiving plate 12 rolls into the placement table 4, after the workpiece leaves the receiving plate 12, the fixed plate 9 is pulled back to the original position under the rebound of the reset tension spring 13, and the elastic water belt 5 and the receiving plate 12 also return to the original position.
