Description

Technical Field

[0001] The present application relates to the technical field of tool cleaning, and in particular to a tool cleaning device and a tool cleaning system for a machining center. Background Art

[0002] In the field of mechanical processing, machining centers are widely used for precision processing of various parts. During the processing, the tool is in direct contact with the workpiece, and will inevitably be contaminated with a large amount of chips, oil and other pollutants generated during the processing. If these pollutants cannot be removed in a timely and effective manner, they will have many adverse effects on the performance and life of the tool and the quality of the subsequent processed workpiece.

[0003] Most of the existing devices use a simple spray structure to spray the cleaning liquid on the surface of the tool through a nozzle, and use a rotating mechanism to drive the tool to rotate to achieve multi-directional cleaning. However, this type of device has many defects: the tool is composed of multiple spiral blades, and spiral tool grooves are formed between adjacent spiral blades. When there are stubborn adhesives (such as sintered metal chips, hardened oil stains, etc.) in the spiral tool grooves, the existing cleaning devices may not be able to effectively remove them. These stubborn stains may be formed during high-temperature processing, and it is difficult to decompose and rinse them off with conventional cleaning fluids and cleaning methods alone. Therefore, there is an urgent need to develop a more efficient, intelligent, precise and environmentally friendly tool cleaning device for machining centers to overcome the defects of the existing technology, improve the overall level of tool cleaning, and ensure the stable operation and processing quality of the machining center. Summary of the invention

[0004] The purpose of the present application is to provide a tool cleaning device and a tool cleaning system for a machining center in order to improve the tool cleaning efficiency.

[0005] In the first aspect, a tool cleaning device for a machining center provided in the present application adopts the following technical solution: it includes a machine tool body, a support frame on which the machine tool body is installed, a plurality of rotating tables rotatably connected to the support frame, a first cleaning rod and a second cleaning rod installed on the rotating table, and a rotating assembly and a lifting assembly installed on the support frame, wherein the end of the first cleaning rod is rotatably connected to the end of the second cleaning rod, the first cleaning rod and the second cleaning rod are both connected to the lifting assembly, the first cleaning rod and the second cleaning rod are driven to rotate by the lifting assembly, so that the angle formed by the first cleaning rod and the second cleaning rod changes, and the rotating assembly is used to drive the rotating table to rotate, so that the orientation of the first cleaning rod and the second cleaning rod changes.

[0006] By adopting the above scheme, the ends of the first cleaning rod and the second cleaning rod are rotatably connected to each other, and the angle formed by the two cleaning rods can be changed in conjunction with the lifting component. During actual cleaning, the angle between the cleaning rods can be flexibly adjusted according to the different shapes and sizes of the tools, so as to better fit the tool surface and ensure that all parts can be effectively covered, thereby enhancing the comprehensiveness and accuracy of cleaning; the rotating component is used to drive the rotating table to rotate, and the first cleaning rod and the second cleaning rod are tilted, so that the first cleaning rod and the second cleaning rod can better adapt to the spiral angle of the tool. When the tool rotates, the cleaning rod can apply a scraping force to the tool in the spiral direction, thereby removing sintered metal chips and hardened oil stains.

[0007] Preferably, the lifting assembly includes a first sliding rod and a second sliding rod passing through the rotating table, a first lifting rod and a second lifting rod passing through the supporting frame, a first connecting rod respectively hinged to the first sliding rod and the first lifting rod, and a second connecting rod respectively hinged to the second sliding rod and the second lifting rod, the first sliding rod passes through the second sliding rod, the second lifting rod passes through the first lifting rod, the first lifting rod and the second lifting rod are connected by a sliding key, the supporting frame is provided with a first power source and a second power source, the output end of the first power source is fixedly connected to the end of the first lifting rod, and the output end of the second power source is fixedly connected to the second lifting end.

[0008] By adopting the above scheme, in the environment of a machining center where space is relatively limited, the structure of the lifting assembly can be made more compact by passing the first slide bar through the second slide bar and the second lifting rod through the first lifting rod. During the operation of the cleaning device, the first cleaning rod will be subjected to various forces, such as contact force with the tool. These forces need to be transmitted and balanced through the lifting assembly. The through-structure between the first slide bar and the second slide bar, and the first lifting rod and the second lifting rod can evenly distribute the force between these rods. When the cleaning rod is subjected to a large reaction force from the tool, this force can be transmitted to the entire lifting assembly through the connection between the first slide bar and the second slide bar, and due to their through-relationship, the force can be dispersed in multiple directions, avoiding the situation where excessive local force causes damage to components.

[0009] The articulated connection adopts a ball hinge connection, which provides three degrees of freedom of movement between components. When the turntable rotates, the connecting rod system composed of the first sliding rod, the second sliding rod, the first connecting rod, the second connecting rod, the first lifting rod and the second lifting rod changes, so that the force transmission between the rods changes in space. The ball hinge makes the connecting rod system more flexible.

[0010] Preferably, the second cleaning rod is provided with an arc-shaped notch, and the end of the second cleaning rod can abut against the inner wall of the tool spiral groove, and the tool spiral groove is located at the arc-shaped notch.

[0011] By adopting the above solution, since the outer edge of the spiral surface of the spiral knife groove is tilted, the arc-shaped notch can accommodate the tilted edge, so that the end of the second cleaning rod can better abut against the spiral knife groove.

[0012] Preferably, the end of the second cleaning rod is rotatably connected to the rotating table, the first cleaning rod is provided with a first slide groove, the second cleaning rod is provided with a second slide groove, the end of the first slide rod is slidably connected to the first slide groove, and the end of the second slide rod is slidably connected to the second slide groove.

[0013] By adopting the above solution, the end of the first slide bar is slidably connected to the first slide groove, and the end of the second slide bar is slidably connected to the second slide groove. This sliding connection mode enables the cleaning rod to adjust the position and angle under the drive of the lifting assembly. When the first slide bar and the second slide bar are in the lifting process, the sliding in the slide groove can drive the cleaning rod to move accordingly.

[0014] Preferably, the end of the second cleaning rod is rotatably connected to the first connecting rod, the rotating table is rotatably connected to the second connecting rod, the second connecting rod rotates with the first connecting rod, the first connecting rod is provided with a third sliding groove, the third sliding groove is provided with a first supporting assembly, the first supporting assembly is rotatably connected to the rotating table, and the first supporting assembly has at least two component forces perpendicular to the plane where the first connecting rod and the second connecting rod are located.

[0015] By adopting the above solution, the first connecting rod, the second connecting rod, the second cleaning rod and the rotating table form a four-bar mechanism, which extends the force area of ​​the second cleaning rod force system and enhances the left and right stability of the screw mechanism, which is equivalent to increasing the stability of the second cleaning rod.

[0016] Preferably, the first support assembly includes a support block slidably connected to the third slide groove, at least two first support rods rotatably connected to the support block, and at least two first sleeves rotatably connected to the rotating table, the first support rod is slidably connected to the first sleeve, the first support rod and the first sleeve are provided with a first spring, and the first spring forces the first support rod to move toward the first slide rod.

[0017] By adopting the above scheme, the support block is slidably connected to the third slide groove of the first connecting rod, which enables the support block to slide freely in the slide groove. When the first connecting rod moves, the position of the support block will change accordingly, and its sliding movement can be adaptively adjusted according to the movement state of the cleaning rod; because the spiral surface of the tool spiral groove is inclined and the spiral rises, the first cleaning rod in contact with it will be subjected to three-directional force components, one of which is perpendicular to the plane where the first cleaning rod and the second cleaning rod are located, but due to the existence of the first support rod and the first sleeve, the stability of the entire force system is better maintained, wherein when the first connecting rod moves with the second cleaning rod, the first connecting rod will press the first spring downward during the movement, so that the first support rod and the first sleeve have a better support effect.

[0018] Preferably, the rotating assembly includes a rotating sleeve rotatably connected to the support frame, a plurality of folding rods fixedly connected to the rotating sleeve, and a worm gear fixedly connected to the rotating sleeve. The support frame is rotatably connected to a worm and a lever hinged to the folding rod. The lever is slidably connected to the rotating table. The rotating sleeve sliding key is connected to the first lifting rod. The support frame is provided with a third power source for driving the worm to rotate.

[0019] By adopting the above solution, the rotating table, the rotating sleeve and the lever constitute a spatial force system. When the rotating sleeve rotates, the lever drives the rotating table to rotate, so that the vertical plane where the first cleaning rod and the second cleaning rod are located is tilted to adapt to the spiral surface of the spiral knife groove.

[0020] Preferably, the support frame is provided with a spray pipe, and the spray pipe is oriented toward the central symmetric point of the plurality of rotating tables.

[0021] By adopting the above scheme, spraying mainly removes those attachments on the tool that are relatively easy to remove.

[0022] In a second aspect, the present application provides a tool cleaning system, which includes, in addition to the above-mentioned machining center tool cleaning device, Tool database, which contains the structural parameters of different types of tools; A control unit capable of controlling the first power source, the second power source, the third power source and the spindle output status; Recording unit, obtains the tool model clamped by the spindle of the machining center; The mapping unit obtains the tool structure parameters of the corresponding model from the tool database according to the tool model recorded by the recording unit, and outputs the control signals of the first power source, the second power source, the third power source and the spindle to the control unit; The specific process is as follows: each time the spindle obtains a tool from the tool magazine, the recording unit records the obtained tool model, and after the spindle processing is completed, the tool is moved above the tool cleaning device of the machining center, and the mapping unit obtains the tool model from the recording unit, and transmits the control signal of the corresponding tool stored in advance to the control unit, and the control unit controls the output status of the first power source, the second power source, the third power source and the spindle, so that the inclination angle and the angle of the first cleaning rod and the second cleaning rod match the corresponding tool. By adopting the above technical solution, the tool database records the structural parameters of different types of tools. These structural parameters cover key information such as tool shape (such as straight edge, spiral edge, etc.), size (length, diameter, etc.), blade angle, etc. By establishing such a database, detailed data basis is provided for the subsequent precise implementation of cleaning operations according to specific tool models; The mapping unit obtains the tool structure parameters of the corresponding tool model from the tool database based on the tool model recorded by the recording unit, and then sends the control signal of the corresponding tool cleaning stored in advance to the control unit. It essentially realizes the key conversion process from tool identification to cleaning control signal generation; through multiple experiments and multiple adjustments, the control signals of different tool cleaning processes are obtained.

[0023] Through close collaboration between various units and an orderly cleaning process, the tool cleaning system makes full use of the tool structure parameter information to achieve intelligent and precise cleaning of tools of different types. It is expected to solve the problems of insufficient versatility and unstable cleaning effect in the traditional tool cleaning process, and improve the overall level of tool cleaning in machining centers.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The angle between the first cleaning rod and the second cleaning rod is controlled by the lifting assembly, which can adapt to the width of the spiral knife groove of different types of tools, so that the first cleaning rod and the second cleaning rod can move along the spiral knife groove with the maximum space, thereby improving the cleaning effect and adaptability; the first connecting rod and the second connecting rod are connected by a ball hinge, which can adapt to the spatial change of the connection between the lifting assembly and the cleaning rod when the rotating table rotates, and ensure that the first sliding rod and the second sliding rod move along the plane where the cleaning rods are located; the first connecting rod, the second connecting rod and the first supporting rod are coordinated with each other, and the force of the first spring is used to offset part of the force component, so that the force system is stable, the rod is prevented from bending, and the stability and reliability of the device are improved.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 -Attached Fig. 9 This application is described in further detail.

[0029] The embodiment of the present application discloses a tool cleaning device for a machining center.

[0030] Example 1, reference Figure 1 , Figure 2 and Figure 3, comprising a machine tool body 1, a support frame 2 mounted on a mobile platform of the machine tool body 1, three rotating tables 3 distributed at equal angles and rotatably connected to the supporting frame 2, a first cleaning rod 31 and a second cleaning rod 32 mounted on the rotating table 3, and a rotating assembly 6 and a lifting assembly 5 mounted on the supporting frame 2, the rotating table 3 can slide toward the central symmetric point, the ends of the first cleaning rod 31 and the second cleaning rod 32 are rotatably connected, and the lifting assembly 5 is respectively connected to the first cleaning rod 31 and the second cleaning rod 32, so that the angle between the first cleaning rod 31 and the second cleaning rod 32 can be controlled by the lifting assembly 5 , so as to adapt to the spiral tool groove width of different types of tools. The rotating component 6 is connected to the lifting component 5 with a sliding key. The rotating component 6 is respectively connected to the three rotating tables 3. When the rotating component 6 rotates, the three can rotate toward the same side, thereby changing the inclination direction of the plane where the first cleaning rod 31 and the second cleaning rod 32 are located, so that the ends of the first cleaning rod 31 and the second cleaning rod 32 can move better along the tool groove, reducing scratches on the tool groove. The lifting component 5 can rotate with the rotating component 6. The support frame 2 is provided with a spray pipe 4, and the spray pipe 4 faces the central symmetrical point of several rotating tables 3.

[0031] refer to Figure 4 , Figure 5 and Figure 6The lifting assembly 5 includes a first connecting rod 53 and a second connecting rod 54, a first lifting rod 51 and a second lifting rod 52 rotatably connected to the support frame 2, and a first sliding rod 56 and a second sliding rod 55 slidably connected to the rotating table 3. The first cleaning rod 31 is provided with a first sliding groove 311, and the first sliding rod 56 is slidably connected to the first sliding groove 311 through a pin. The second cleaning rod 32 is provided with a second sliding groove 321, and the second sliding rod 55 is slidably connected to the second sliding groove 321 through a pin. One end of the second cleaning rod 32 is rotatably connected to the rotating table 3. Since both ends of the second cleaning rod 32 are constrained, when the second sliding rod 55 is stationary, the movement of the first cleaning rod 31 will not affect the second cleaning rod 32, and only the angle between the first cleaning rod 31 and the second cleaning rod 32 can be adjusted; since only one end of the first cleaning rod 31 is constrained by about When the first slide bar 56 is stationary, the second slide bar 55 can affect the position of the first cleaning rod 31. After the model of the tool is determined, the first cleaning rod 31 and the second cleaning rod 32 are adjusted to the preset positions so that the first cleaning rod 31 and the second cleaning rod 32 can partially move along the tool spiral groove. The support frame 2 is fixedly connected with a first power source 57 and a second power source 58 that respectively drive the first lifting rod 51 and the second lifting rod 52 to move. In this embodiment, the first power source 57 and the second power source 58 are electric push rods, and can also be hydraulic push rods, screw tables, etc.; since the outer edge of the spiral surface of the spiral knife groove is warped, in order to prevent the second cleaning rod 32 from interfering with the rotation of the tool, an arc-shaped notch 322 is provided on the second cleaning rod 32, and the arc-shaped notch 322 can accommodate the warping of the spiral knife groove.

[0032] refer to Figure 5 and Figure 6 The two ends of the first connecting rod 53 are respectively connected to the first lifting rod 51 and the first sliding rod 56 through ball hinges, and the two ends of the second connecting rod 54 are respectively connected to the second lifting rod 52 and the second sliding rod 55 through ball hinges. The first lifting rod 51 passes through the second lifting rod 52, and the first lifting rod 51 and the second lifting rod 52 are connected by a sliding key. Since the lifting assembly 5 drives three groups of first cleaning rods 31 and second cleaning rods 32 at the same time, when the rotating assembly 6 rotates the rotating table 3, the connection between the lifting assembly 5 and the first cleaning rod 31 and the second cleaning rod 32 will undergo spatial changes. The multi-degree-of-freedom of the ball joint can better adapt to such changes in the spatial structure, so that the first sliding rod 56 and the second sliding rod 55 can also move along the plane where the first cleaning rod 31 and the second cleaning rod 32 are located.

[0033] refer to Figure 4The second cleaning rod 32 end is rotatably connected to the first connecting rod 33, the rotating table 3 is rotatably connected to the second connecting rod 34, the second connecting rod 34 rotates with the first connecting rod 33, the second connecting rod 34 has a third sliding groove 331, and a supporting block 332 is slidably connected in the third sliding groove 331. The supporting block 332 is fixedly connected to the limiting plates 333 on both sides, and the limiting plates 333 abut against the side of the second connecting rod 34. The limiting plates 333 on both sides are rotatably connected to the first supporting rod 35, and the rotating table 3 is rotatably connected to two first sleeves 36. One end of the first supporting rod 35 extends into the first sleeve 36 and can move along the first sleeve 36. A first spring is provided between the first supporting rod 35 and the first sleeve 36. The plane where the two first supporting rods 35 are located is aligned with the first sleeve 36. The planes where the first connecting rod 33 and the second connecting rod 34 are located are perpendicular. The first connecting rod 33 moves along with the second cleaning rod 32. The first spring will be compressed during the movement of the first connecting rod 33. The reaction force of the spring becomes stronger and stronger during the compression of the first spring, so that the supporting force of the first support rod 35 becomes stronger and stronger. Since the spiral knife groove is a curved surface, when the first cleaning rod 31 abuts against the spiral groove, the first cleaning rod 31 will be subjected to a force perpendicular to the curved surface, which can be divided into three component forces. One component force is perpendicular to the plane where the first cleaning rod 31 and the second cleaning rod 32 are located. This component force will cause the rod in the force system to bend. Under the action of the first spring, the first support rod 35 can offset this component force, so that the entire force system is in a stable state.

[0034] refer to Figure 7 and Figure 8 The rotating assembly 6 includes a rotating sleeve 61 rotatably connected to the support frame 2, a folding rod 62 fixedly connected to the rotating sleeve 61, and a worm wheel 64 fixedly connected to the rotating sleeve 61. The support frame 2 is rotatably connected with a worm 65 and a lever 63 hinged on the folding rod 62. The rotating sleeve 61 is sleeved on the first lifting rod 51, and the rotating sleeve 61 is connected to the first lifting rod 51 with a sliding key. One end of the lever 63 is slidably connected to the rotating table 3, and the other end is connected to the rotating sleeve 61 through a ball hinge. In this way, the rotating table 3, the lever 63 and the rotating sleeve 61 constitute a spatial force system. When the rotating sleeve 61 rotates, it can drive the three rotating tables 3 to rotate synchronously and in the same direction at the same time. A third power source 66 for driving the worm 65 to rotate is provided on the support frame 2. In this embodiment, the third power source 66 takes a motor as an example. On the one hand, the worm 65 and the worm wheel 64 have a low transmission ratio and can more accurately control the rotation angle of the rotating sleeve 61. On the other hand, they also have a self-locking function.

[0036] Taking the cleaning of the T100 tool as an example, the machining center starts the machining task, and the spindle selects the T100 tool from the tool magazine for machining according to the program instructions. At this time, the recording unit synchronously records the model of the tool clamped by the spindle; when the spindle completes the machining task of the tool, according to the coordinate positioning system of the machining center, the tool is moved to a specific position above the tool cleaning device. This position is precisely designed to ensure that the various components of the cleaning device and the tool cooperate effectively; after the mapping unit obtains the tool model "T100" from the recording unit, it retrieves its corresponding structural parameters in the tool database, specifically, the total length of the tool is 200mm, the blade length is 50mm, the handle diameter is 25mm, the blade shape is spiral and the helix angle is 30 degrees; the data obtained based on multiple tests and entered into the mapping unit are The third power source 66 controls the worm 65 to rotate 14 circles, so that the worm wheel 64 rotates 25.6°, so that the plane where the first cleaning rod 31 and the second cleaning rod 32 are located is tilted 30°, and the output end of the first power source 57 moves downward by 45mm, driving the first cleaning rod 31 to rotate to an angle of 40 degrees with the horizontal direction. The second power source 58 pushes the second cleaning rod 32 to extend 100mm and form an angle of 70 degrees with the first cleaning rod 31. The spindle rotates slowly at a speed of 12 rpm and moves up and down at 140mm / min, so that the first cleaning rod 31 and the second cleaning rod 32 can move along the tool groove.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
