Description

Technical Field

[0001] The invention belongs to the technical field of machine tool processing, in particular to a multi-axis vertical CNC machine tool. Background Art

[0002] A CNC lathe is a high-precision, high-efficiency automated machine tool that can be used to process complex workpieces such as straight cylinders, oblique cylinders, arcs, and various threads, grooves, worms, etc. Multi-spindle vertical CNC lathes are designed to meet the needs of simultaneous processing of multiple workpieces. They can process multiple workpieces at the same time in the same lathe. Multi-spindle vertical CNC special-purpose lathes are usually used for processing parts of special shapes. During processing, the workpiece generally does not rotate, but is processed by the relative movement of the tool and the workpiece. With the rapid development and industrial upgrading of China's manufacturing industry, the market demand and industry prospects of CNC processing technology are constantly expanding.

[0003] Since multi-axis vertical machine tools can control the blades more flexibly when processing blanks, it is necessary to ensure the smoothness of their rotating joints. However, when the cutter head is performing cutting, drilling and other tasks, some of the residual slag separated from the blank will diffuse into the air, and then gradually adhere to the rotating joints of the tool control arm. After working for a long time, it will cause serious wear on the joints, and even the problem of excessive slag accumulation and jamming the joints, so improvements are needed.

[0009] Furthermore, the outer surface of the adsorption slide rod is slidably connected to the inner cavity of the facing arc plate through a through hole, the end of the adsorption slide rod close to the cutting blank is fixedly connected with a pressure-sensitive end, the end of the propulsion hose close to the cutting blank is mutually squeezed with the outer surface of the facing arc plate, the end of the propulsion hose away from the cutting blank is slidably connected to the inner wall of the fixed sleeve through a plug-in sleeve, and the end of the spring washer away from the plug-in sleeve is fixedly connected to the inner wall of the fixed sleeve. The upper surface of the longitudinal slide plate is slidably connected to the top of the inner wall of the outer protective shell through a moving roller, the outer surface of the propulsion thin rod is slidably connected to the inner wall of the guide slide cylinder through a sleeve wheel, and a through groove is opened at the axis of the inner cavity of the guide slide cylinder, and the top of the propulsion rod tube is slidably connected to the top of the inner wall of the outer protective shell.

[0010] Furthermore, the clamping device includes a support plate, adsorption mesh holes are evenly opened at the axis center of the inner cavity of the support plate, an axial pull cylinder is fixedly connected at the axis center of the lower surface of the support plate, a spring pull rope is evenly arranged in the inner cavity of the axial pull cylinder, a bent slide rod is fixedly connected to the end of the spring pull rope away from the axial pull cylinder, a sliding clamp is fixedly connected to the top of the bent slide rod, a pressure rod is evenly arranged in the inner cavity of the sliding clamp, and a height adjustment frame is evenly arranged on the side of the support plate.

There are four sliding clamps, the outer surface of the bending slide rod is slidingly connected to the inner wall of the support plate through the guide slide groove, and the bottom of the height adjustment frame is fixedly connected to the bottom of the inner wall of the outer protective shell. The top of the height adjustment frame is slidingly connected to the side of the support plate through the transfer slide groove, the end of the spring pull rope away from the bending slide rod extends to the inside of the axial pull tube through the through opening, and the end of the spring pull rope away from the bending slide rod is slidingly connected to the inner wall of the axial pull tube through the reel.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. When the cutting tool is cutting, drilling and other operations, some of the residual slag detached from the cutting blank will diffuse into the air, and then gradually adhere to the rotating joints of the cutting parts. After working for a long time, it will cause serious wear on the joints, and even the problem of too much slag accumulating and getting the joints stuck. In order to solve the above problems, an adsorption slide bar for guiding the airflow is set around the cutting blank, so that the debris detached from the cutting blank is settled downward with the airflow, greatly reducing the amount of debris floating in the area above the outer protective shell, thereby protecting the rotating joints of the cutting parts.

[0014] 2. When the modified slide rod is performing adsorption work, the stamping motor can drive the adsorption slide rod to continuously hit the side of the cutting blank by controlling the sliding of the propulsion hose, so that the accumulated debris on the upper surface of the cutting blank can be shaken off, thereby achieving the effect of cleaning the residual debris of the cutting blank. Since the threaded rotating rod is located inside the propulsion hose, when the mesh of the adsorption slide rod is blocked, the adsorption slide rod can be replaced to quickly ensure that the modified slide rod always has the adsorption effect to avoid affecting the subsequent processing work.

[0015] 3. The device uses four sliding clamps to synchronously clamp the middle of the cutting blank. Before the sliding clamp fixes the cutting blank, a test pressure rod is first used to squeeze the cutting blank relative to the pressure rod. As the pressure rod shrinks to the sliding clamp, the pulling speed of the axial pull cylinder is reduced, thereby avoiding the problem of excessive pulling of the axial pull cylinder causing indentations on the side of the cutting blank due to excessive clamping. At the same time, the clamping equipment is protected to avoid overload damage to the axial pull cylinder.

[0016] 4. The device can rotate the adsorption slide rod relative to the support plate at a certain angle by twisting the support plate, thereby expanding the action range of each adsorption slide rod from a straight line to a fan-shaped range, improving the adsorption effect of the adsorption slide rod, and using centrifugal force to throw the large pieces of residual material cut off from the upper surface of the support plate to the bottom of the inner wall of the outer protective shell, thereby eliminating the interference factor of the accumulated residual material on the cutting knife.

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0028] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a multi-axis vertical CNC machine tool, comprising a machine tool outer box 1, a cutting component 3 is arranged on the top of the inner wall of the machine tool outer box 1, a clamping device 4 is arranged at the axis of the bottom of the inner wall of the machine tool outer box 1, and a cutting blank 7 is arranged in the middle of the clamping device 4;

[0029] The machine tool outer box 1 includes an outer protective shell 11, and side baffles 12 are rotatably connected to the left and right sides of the inner wall of the outer protective shell 11, a shutter cylinder 13 is fixedly connected to the top of the front of the outer protective shell 11, and a front baffle 14 is slidably connected to the inner wall of the shutter cylinder 13, a searchlight 2 is arranged in the middle of the inner wall of the outer protective shell 11, and drainage devices 5 are symmetrically arranged on the left and right sides of the bottom of the inner wall of the outer protective shell 11;

[0030] The cutting component 3 includes a fixed frame 31 and a longitudinal slide plate 33. The front and rear sides of the lower surface of the fixed frame 31 are symmetrically provided with transverse guide rails 32. The inner wall of the transverse guide rail 32 is slidably connected with a propulsion rod cylinder 36. The bottom end of the output shaft of the propulsion rod cylinder 36 is fixedly connected with a guide slide cylinder 35. The two sides of the lower surface of the longitudinal slide plate 33 are symmetrically provided with propulsion thin rods 34. The propulsion thin rods 34 can only drive the related components below to slide in a directional manner along the grooves passing through the guide slide cylinder 35. In order to ensure that the propulsion thin rod 34 can slide stably, the propulsion thin rod 34 is located inside the guide slide cylinder 35, and a pulley sleeve is put on to lower the propulsion thin rod The friction resistance between 34 and the inner wall of the guide slide 35, and the pushing rod 34 can slide vertically without the problem of tilting or misalignment relative to the guide slide 35. The bottom end of the pushing rod 34 is fixedly connected with a main rotating joint 37, and the bottom of the outer surface of the main rotating joint 37 is fixedly connected with a secondary rotating joint 38 through a rotating plate. The bottom of the secondary rotating joint 38 is symmetrically provided with a torque motor 39 through a rotating plate, and the outer surface of the output shaft of the torque motor 39 is fixedly connected with a cutting cutter 310. The rotation directions of the main rotating joint 37 and the secondary rotating joint 38 are staggered to ensure that the degree of freedom of the cutting cutter 310 is high enough.

[0031] The drainage device 5 includes a veneer arc plate 51, and modified sliding rods 6 are symmetrically arranged on both sides of the inner cavity of the veneer arc plate 51. The side of the modified sliding rod 6 away from the veneer arc plate 51 is fixedly connected to a clustering push plate 52, and both sides of the outer surface of the clustering push plate 52 are fixedly connected to the outer surface of the veneer arc plate 51 through spring belts 53. The end of the modified sliding rod 6 away from the veneer arc plate 51 is slidably connected to a fixed sleeve 54, and the end of the fixed sleeve 54 away from the modified sliding rod 6 is fixedly connected to a stamping motor 55.

[0032] The modified slide bar 6 includes an adsorption slide bar 61, the inner wall of which is slidably connected with a propulsion hose 63, the end of the propulsion hose 63 away from the adsorption slide bar 61 is slidably connected with a plug-in sleeve 65, the outer surface of the plug-in sleeve 65 is fixedly connected with a spring washer 64, the inner wall of the plug-in sleeve 65 is fixedly connected with an embedded fixing disk 67 at one end close to the adsorption slide bar 61, the middle part of the inner cavity of the embedded fixing disk 67 is fixedly connected with a built-in motor 66, the outer surface of the output shaft of the built-in motor 66 is fixedly connected with a threaded rotating rod 68, and the top end of the propulsion hose 63 has an outer shell to ensure that when the propulsion hose 63 slides out from the inside of the fixed sleeve 54, the adsorption slide bar 61 can be pushed toward the direction close to the cutting blank 7 by pushing the cluster push plate 52.

[0033] The outer surface of the adsorption slide bar 61 is slidably connected with the inner cavity of the facing arc plate 51 through the through hole. The end of the adsorption slide bar 61 close to the cutting blank 7 is fixedly connected with the pressure-sensitive end 62. The end of the propulsion hose 63 close to the cutting blank 7 is mutually squeezed with the outer surface of the facing arc plate 51. The end of the propulsion hose 63 away from the cutting blank 7 is slidably connected with the inner wall of the fixed sleeve 54 through the plug-in sleeve 65, and the end of the spring washer 64 away from the plug-in sleeve 65 is fixedly connected with the inner wall of the fixed sleeve 54. The upper surface of the longitudinal slide plate 33 is slidably connected with the top of the inner wall of the outer protective shell 11 through the moving roller, the outer surface of the propulsion thin rod 34 is slidably connected with the inner wall of the guide slide 35 through the sleeve wheel, and a through groove is opened at the axis of the inner cavity of the guide slide 35, and the top of the propulsion rod tube 36 is slidably connected with the top of the inner wall of the outer protective shell 11.

[0034] Before using the device to machine the cut blank 7, first open the side baffles 12 on the left and right sides, and retract the front baffle 14 through the front roller shutter 13, and then place the cut blank 7 at the axis of the clamping device 4 to complete the loading work. Figure 3 As shown, the three sides of the machine tool outer box 1 are then completely closed, and the internal cutting components 3 and drainage devices 5 are controlled by corresponding remote control devices to start machine tool processing.

[0035] The longitudinal sliding plate 33 fits against the top of the inner wall of the outer protective shell 11 and slides laterally, thereby driving the two ends of the guide slide 35 to slide along the transverse guide rail 32 through the pushing rod 34. Since the height of the guide slide 35 is fixed, the equipment below the main rotating joint 37 can slide downward relative to the guide slide 35 by pushing the pushing rod 34 downward. A cutting groove for guiding the longitudinal sliding of the pushing rod 34 is opened at the axis of the guide slide 35, and the guide slide 35 itself is installed in a longitudinal setting, so the cutting knife 310 will not have the problem of being unable to move to a dead angle in the plane during the cutting process.

[0036] The rotation directions of the main rotating joint 37 and the auxiliary rotating joint 38 are staggered with each other, which can ensure that the cutting tool 310 can deflect freely. The cutting tool 310 on the corresponding side is rotated at high speed by the torque motor 39, so that the cutting tool 310 can cut the outer surface of the cutting blank 7, and the cutting tool 310 on the non-working side can be used as a spare tool.

[0037] After the cutting blank 7 is placed on top of the clamping device 4, the stamping motors 55 located on both sides push the modified slide bar 6 outward through the fixed sleeve 54. At this time, the propulsion hose 63 slides outward from the inner wall of the fixed sleeve 54. Since the propulsion hose 63 is a hose, under the thrust of the plug-in sleeve 65, the propulsion hose 63 will drive the adsorption slide bar 61 to be pushed forward when it slides outward, but the spring washer 64 on the outer surface of the plug-in sleeve 65 will continue to be squeezed. After the cluster push plate 52 is pushed by the end of the propulsion hose 63, the adsorption slide bar 61 will be pushed in the direction of the side of the cutting blank 7, so the adsorption slide bar 61 will clamp the cutting blank 7 through the pressure-sensitive end 62.

[0038] During the cutting operation, the built-in motor 66 located at the top of the inner wall of the propulsion hose 63 drives the threaded rotating rod 68 to rotate counterclockwise at high speed, so that the mesh of the adsorption slide bar 61 has adsorption capacity, thereby draining the debris generated by the cutting downward to prevent dust residue from floating in the air and spreading to the upper part of the outer protective shell 11, and the stamping motor 55 can indirectly stop the stamping work, so that the propulsion hose 63 and the adsorption slide bar 61 are pulled back to the initial position under the squeezing action of the spring washer 64, and the elastic potential energy of the spring will push the adsorption slide bar 61 to continuously hit the side of the middle cutting blank 7, so that the cutting blank 7 shakes off the debris accumulated on the outer surface, thereby removing the debris remaining on the cutting blank 7.

[0039] Example 2, please refer to Figure 1-Figure 9 The present invention provides a technical solution: on the basis of embodiment 1, the clamping device 4 includes a support plate 41, and adsorption mesh holes 44 are evenly opened at the axis center of the inner cavity of the support plate 41, and an axis pull cylinder 43 is fixedly connected at the axis center of the lower surface of the support plate 41, and the inner cavity of the axis pull cylinder 43 is evenly provided with a spring pull rope 45, and the end of the spring pull rope 45 away from the axis pull cylinder 43 is fixedly connected to a bent slide rod 46, and the top of the bent slide rod 46 is fixedly connected to a sliding clamp block 47, and the inner cavity of the sliding clamp block 47 is evenly provided with a pressure rod 48, and the side of the support plate 41 is evenly provided with a height adjustment frame 42.

[0040] The bottom of the inner wall of the veneer arc plate 51 is fixedly connected to the upper surface of the support plate 41, the bottom of the cutting blank 7 is pressed against the axis of the upper surface of the support plate 41 through the adsorption mesh 44, and the outer surface of the sliding clamp 47 is pressed against the outer surface of the cutting blank 7 through the pressure rod 48. There are four sliding clamps 47, the outer surface of the bending slide 46 is slidably connected to the inner wall of the support plate 41 through the guide slide, and the bottom of the height adjustment frame 42 is fixedly connected to the bottom of the inner wall of the outer protective shell 11. The top of the height adjustment frame 42 is slidably connected to the side of the support plate 41 through the transfer slide, the end of the spring pull rope 45 away from the bending slide 46 extends to the inside of the axial pull tube 43 through the through opening, and the end of the spring pull rope 45 away from the bending slide 46 is slidably connected to the inner wall of the axial pull tube 43 through the reel.

[0041] After the cutting blank 7 is placed at the axis center of the upper surface of the support plate 41, the support plate 41 stabilizes the bottom of the cutting blank 7 through the adsorption effect of the adsorption mesh 44 in the middle, and then the axial pull tube 43 at the bottom synchronously contracts the spring pull ropes 45 around it. At this time, the bent slide rod 46 pulls the sliding clamp 47 to fit the arc surface of the cutting blank 7, and finally the pressure rod 48 is pressed into the inside of the sliding clamp 47 by the side of the cutting blank 7, and the sliding clamp 47 fits the cutting blank 7 to clamp it.

[0042] The height-adjusting frame 42 can adjust the actual height of the support plate 41, and the ball at its end can roll in the side groove of the support plate 41 through rolling friction, thereby deflecting the support plate 41, and then causing the adsorption slide bar 61 to rotate at a certain angle relative to the support plate 41, thereby expanding the actual range of action of the adsorption slide bar 61.

[0043] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
