Description

Technical Field

[0001] The present invention relates to the technical field of post - processing of artificial stone plates, and particularly to a floating power head for processing artificial stone plates. Background Art

[0002] In the field of stone processing, especially in the post - processing technology of artificial stone countertops such as kitchen washbasins, it is often necessary to open a variety of functional holes and grooves inside the plates, including basin holes for embedding washbasins, stove holes for installing gas stoves, faucet holes for fixing faucets, etc. In addition, it is also necessary to carry out fine processing on the outer edge of the plate according to design requirements, such as cutting curves, oblique lines or irregular contours required for special - shaped countertops. To ensure a smooth transition between the notch edge and the installation components (such as washbasins), it is also necessary to perform rounding or chamfering on the edge of the basin hole or stove hole. During processing, the artificial stone plate is usually horizontally fixed on the workbench, and the power head completes the cutting operation according to the preset path and size.

[0003] The current mainstream driving schemes mostly adopt multi - degree - of - freedom robotic arms or XYZ three - dimensional linear driving systems, and their mechanical structures are based on gantry frames, column - beam combinations or slide - rail - slide - rail units, which belong to the general technologies in the industry. However, the existing technologies have the following limitations:

[0004] (1) Limited motion dimensions: The driving mechanism only supports linear motion in a single direction. For example, when processing a rectangular basin hole, the power head needs to move alternately in the horizontal or vertical direction and cannot achieve multi - direction composite motion;

[0005] (2) Inefficient replacement of the grinding and cutting terminal: The grinding and cutting terminals (such as cutting tool heads, grinding heads) carried by the power head need to be manually disassembled and replaced, which is difficult to meet the requirements of multi - process continuous processing;

[0006] (3) Prominent structural interference problems: When performing internal decoration operations on basin holes / stove holes, the large size of the power head directly affects the moving range. Most existing power heads use three - jaw chucks to cooperate with universal interfaces to fix the grinding and cutting terminals, and the driving motor is coaxially designed with the power head shaft, resulting in redundant overall axial dimensions and restricting the operation flexibility in narrow spaces. Summary of the Invention

[0041] One of the above technical solutions has the following beneficial effects:

[0042] 1. Break through the limitation of motion dimension and realize composite machining: The traditional driving mechanism only supports linear motion in a single direction, while this solution endows the grinding and cutting terminal with axial self-adaptive ability. Combining the rotation transmission of the terminal driving mechanism and the grinding and cutting terminal, higher-precision machining of rectangular, special-shaped holes and grooves, and curved surfaces can be completed. For example, in the high-precision machining of basin holes, the grinding and cutting terminal can, on the basis of a multi-degree-of-freedom robotic arm or an XYZ three-dimensional linear driving system, fine-tune the axial feed depth through the outer shell to avoid the motion blind area caused by the too large size of the power head in the traditional solution.

[0044] 3. Compact structure, eliminating interference risks: The terminal drive mechanism and the grinding and cutting terminal are driven in a non-coaxial drive form to form a non-coaxial layout. Compared with the traditional coaxial motor design, the overall axial dimension is significantly reduced. Moreover, the axial micro-floating of the outer shell further compresses the axial space requirement for tool operation, enabling the grinding and cutting terminal to perform high-precision finishing processing on the internal area of the basin hole / furnace hole.

Detailed Embodiments

[0051] The technical solutions of the present invention will be further described below in conjunction with the drawings and through specific embodiments.

[0052] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0053] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0054] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] A floating power head for artificial stone plate processing, comprising a mounting base 1, a terminal drive mechanism 2, a nested cylinder and a grinding and cutting terminal 5;

[0056] The mounting base 1 is provided with the terminal drive mechanism 2, and the terminal drive mechanism 2 drives the grinding and cutting terminal 5 to rotate self - sufficiently for processing in a non - coaxial drive form;

[0057] The nested cylinder includes an outer shell 4, an inner shell 3 and an output shaft 6;

[0058] A floating air pipe 7 is communicated inside the outer shell 4, and the floating air pipe 7 drives the inner shell 3 and the output shaft 6 to float along the axial direction of the outer shell 4 in a pneumatic retracting and extending form by supplying or withdrawing air to the outer shell 4;

[0059] A replacement air pipe 8 is communicated inside the inner shell 3, and the replacement air pipe 8 drives the output shaft 6 to realize the disassembly or installation of the grinding and cutting terminal 5 by supplying or withdrawing air to the inner shell 3 and combining the action of a return spring 9.

[0060] As Figure 1-2As shown in the figure, through the unique design of the nested cylinder, the floating power head realizes the floating function of the power head in the axial direction. The floating air pipe 7 drives the inner shell 3 and the output shaft 6 to perform floating motion along the axial direction in the form of pneumatic retraction and extension. The combination of this floating function and the rotation motion of the terminal drive mechanism enables the power head to achieve multi-directional composite motion during the processing of artificial stone plates. For example, when processing a rectangular basin hole, the power head can not only achieve large-scale linear motion in the horizontal or vertical direction by installing the mounting seat 1 on a multi-degree-of-freedom robotic arm or an XYZ three-dimensional linear drive system, but also perform small-scale floating adjustment in the axial direction, so as to better perform fine processing on the plate, breaking through the limitation that the traditional drive mechanism only supports linear motion in a single direction.

[0061] At the same time, the replacement air pipe 8 inside the inner shell 3 realizes the automatic disassembly or installation of the grinding and cutting terminal through ventilation or air intake, combined with the action of the return spring 9. When the grinding and cutting terminal needs to be replaced, the replacement air pipe 8 is ventilated, overcoming the elastic force of the return spring 9, driving the output shaft 6 to act, and separating the grinding and cutting terminal from the power head; after the replacement is completed, the replacement air pipe 8 takes in air, and under the action of the return spring 9, the output shaft 6 resets, firmly installing the new grinding and cutting terminal on the power head. This process reduces manual intervention, greatly improves the efficiency of replacing the grinding and cutting terminal, and meets the requirements of multi-process continuous processing.

[0062] Furthermore, the terminal drive mechanism adopts a non-coaxial drive form, such as the form of a motor, a belt, and a pulley to drive the grinding and cutting terminal to rotate. This design makes the drive shaft of the terminal drive mechanism and the rotating shaft of the power head not in the same horizontal plane, forming a non-coaxial layout, effectively reducing the overall axial dimension of the power head. When performing internal decoration operations on the basin hole / furnace hole, the smaller power head size can move flexibly in a narrow space, avoiding structural interference problems and improving operation flexibility.

[0063] In summary, one technical solution in this technical solution has the following beneficial effects:

[0064] 1. Break through the limitation of motion dimensions and achieve composite processing: The traditional drive mechanism only supports linear motion in a single direction, while this solution endows the grinding and cutting terminal 5 with axial self-adaptive ability. Combined with the rotational transmission of the terminal drive mechanism 2 and the grinding and cutting terminal 5, higher-precision processing of rectangular, special-shaped holes and grooves, and curved surfaces can be completed. For example, in the high-precision processing of basin holes, the grinding and cutting terminal 5 can, on the basis of a multi-degree-of-freedom robotic arm or an XYZ three-dimensional linear drive system, fine-tune the axial feed depth through the outer shell 4, avoiding the motion blind area caused by the too large size of the power head in the traditional solution.

[0065] 2. High-efficiency tool change, supporting multi-process integration: By utilizing the combined action of air pressure and the return spring 9, the replacement time of the grinding and cutting terminal 5 is significantly shortened, remarkably improving the processing efficiency. Meanwhile, the same power head can be adapted to various grinding and cutting terminals 5 such as cutting, grinding, and chamfering, meeting the full-process requirements of table hole opening, edge trimming, surface polishing, etc., and reducing the equipment downtime.

[0066] 3. Compact structure, eliminating interference risks: The terminal drive mechanism 2 and the grinding and cutting terminal 5 are driven in a non-coaxial drive form, forming a non-coaxial layout. Compared with the traditional coaxial motor design, the overall axial dimension is significantly reduced. Moreover, the axial micro-floating of the outer shell 4 further compresses the axial space requirement for the tool operation, enabling the grinding and cutting terminal 5 to perform high-precision finishing processing on the inner area of the basin hole / furnace hole.

[0067] Further description, the outer shell 4 includes a cylinder liner 41 and a seal 42;

[0068] The cylinder liner 41 is fixedly installed on the mounting seat 1. The cylinder liner 41 is sleeved outside the inner shell 3, and there is an air storage space between the inner wall of the cylinder liner 41 and the outside of the inner shell 3. The seal 42 is arranged in the air storage space along the circumference of the inner shell 3 outside the cylinder barrel 32. The seal 42 divides the air storage space into a first air storage chamber 43 and a second air storage chamber 44;

[0069] The cylinder liner 41 is provided with the floating air pipes 7 respectively communicating with the first air storage chamber 43 and the second air storage chamber 44. The two floating air pipes 7 are respectively used for ventilating or deflating the first air storage chamber 43 and the second air storage chamber 44, and pushing the inner shell 3 and the output shaft 6 to move axially along the cylinder liner 41 in a pneumatic retracting and extending form, realizing the axial floating of the inner shell 3 and the output shaft 6.

[0070] The outer shell 4 realizes the axial self-adaptive floating of the grinding and cutting terminal 5 through the linkage of double-chamber air pressure drive and the seal 42. The specific process is as follows:

[0071] As Figure 5 shown, when the floating air pipe 7 communicating with the first air storage chamber 43 ventilates it, and the floating air pipe 7 communicating with the second air storage chamber 44 deflates it, the gas pressure pushes the seal 42 to move along the inner wall of the cylinder liner 41 towards the second air storage chamber 44, compressing the volume of the second air storage chamber 44; when the floating air pipe 7 communicating with the second air storage chamber 44 ventilates it, and the floating air pipe 7 communicating with the first air storage chamber 43 deflates it, the gas pressure pushes the seal 42 to move along the inner wall of the cylinder liner 41 towards the first air storage chamber 43, compressing the volume of the first air storage chamber 43. The movement of the seal 42 forces the connected inner shell 3 and output shaft 6 to move axially relative to the cylinder liner 41. Meanwhile, the axial displacement range of the grinding and cutting terminal 5 connected to the output shaft 6 can be accurately controlled by controlling the air pressure range of the two floating air pipes 7.

[0072] To further illustrate, the inner shell 3 includes a mounting barrel 31 and a cylinder 32;

[0073] The installation cylinder 31 includes an outer sleeve 311 and an inner sleeve 312;

[0074] The output shaft 6 includes a mounting push rod 61 and a piston push rod 62;

[0075] The outer sleeve 311 is sleeved on the outside of the inner sleeve 312, and the mounting push rod 61 is movably installed inside the inner sleeve 312. The outer sleeve 311, the inner sleeve 312 and the mounting push rod 61 are coaxially rotatable, and the inner sleeve 312 and the mounting push rod 61 can both move axially relative to the outer sleeve 311, and the mounting push rod 61 can move axially relative to the inner sleeve 312.

[0076] The cylinder barrel 32 and the inner sleeve 312 are connected by a transmission structure 33. The cylinder sleeve 41 is sleeved on the outside of the cylinder barrel 32. The cylinder barrel 32 can move axially relative to the cylinder sleeve 41. Combined with the transmission effect of the transmission structure 33, the inner sleeve 312 and the mounting push rod 61 can move axially relative to the outer sleeve 311.

[0077] The piston push rod 62 is movably installed inside the cylinder 32, and the piston push rod 62 can move axially relative to the cylinder 32. The piston push rod 62 and the installation push rod 61 are coaxially arranged, and the return spring 9 is installed in the circumference of the piston push rod 62 and the installation push rod 61;

[0078] The cylinder barrel 32 is sealedly connected to a cylinder rear cover 34 at one end away from the inner sleeve 312, and a replacement air cavity 35 is provided between the interior of the cylinder rear cover 34 and the mounting push rod 61, and the replacement air cavity 35 is connected to the replacement air pipe 8;

[0079] The replacement air pipe 8 is used to ventilate or collect air in the replacement air chamber 35, and in a pneumatically driven form, pushes or withdraws the piston push rod 62 and the installation push rod 61 in turn, and combines the action of the reset spring 9 to achieve the disassembly or installation of the grinding and cutting terminal 5.

[0080] Specifically, pneumatic drive replaces manual operation, which greatly reduces the replacement time. The specific process is as follows:

[0081] like Figure 2 and Figure 5As shown, when the replacement air pipe 8 is connected, compressed gas enters the replacement air chamber 35 of the cylinder rear cover 34, pushing the piston ejector rod 62 to move axially along the cylinder barrel 32. Since the piston ejector rod 62 and the installation ejector rod 61 are coaxially arranged, the piston ejector rod 62 pushes the installation ejector rod 61 to move axially along the installation cylinder 31 until one end of the installation ejector rod 61 is completely exposed outside the installation cylinder 31, facilitating the replacement of the grinding and cutting terminal 5. After replacement, the replacement air chamber 35 exhausts and relieves pressure, and the piston ejector rod 62 and the installation ejector rod 61 are respectively reset under the action of the return spring 9, completing the replacement of the grinding and cutting terminal 5.

[0082] Further explanation, a first limiting portion 313 protrudes in the middle inside the inner sleeve 312, and a second limiting portion 611 protrudes on the outer peripheral surface of the installation ejector rod 61. The first limiting portion 313 is arranged close to the outer shell 4, and the second limiting portion 611 is arranged away from the outer shell 4;

[0083] When the inner sleeve 312 moves towards the end away from the outer shell 4, the first limiting portion 313 and the second limiting portion 611 are in contact with each other, causing the inner sleeve 312 and the installation ejector rod 61 to move together;

[0084] When the installation ejector rod 61 moves towards the end away from the outer shell 4, the first limiting portion 313 and the second limiting portion 611 move away from each other, causing the installation ejector rod 61 to move independently.

[0085] The installation cylinder 31 realizes the precise axial floating and rapid installation and disassembly of the installation ejector rod 61 through a double-sleeve coaxial limiting structure. The specific process is as follows:

[0086] As Figure 2 and Figure 4 shown, when the cylinder barrel 32 moves axially along the cylinder liner 41, the inner sleeve 312 is driven to move axially relative to the outer sleeve 311 through the transmission structure 33. Through the contact between the first limiting portion 313 and the second limiting portion 611, the axial displacement range of the installation ejector rod 61 and the grinding and cutting terminal 5 is jointly controlled.

[0087] When installation and disassembly are required, when the installation ejector rod 61 receives the thrust of the piston ejector rod 62 and moves axially relative to the inner sleeve 312, the first limiting portion 313 and the second limiting portion 611 are separated, allowing the installation ejector rod 61 to independently extend out of the inner sleeve 312, realizing the exposure of the quick-release interface on the installation ejector rod 61 during replacement for facilitating the replacement of the grinding and cutting terminal 5. After the thrust of the piston ejector rod 62 is withdrawn, the grinding and cutting terminal 5 is quickly retracted and quickly locked under the action of the return spring 9.

[0088] Further explanation, the transmission structure 33 includes a transmission cylinder 331 and a ball bearing 332;

[0089] The transmission cylinder body 331 is sleeved outside the piston push rod 62, and the transmission cylinder body 331 is not connected to the piston push rod 62, and the piston push rod 62 can axially move relative to the transmission cylinder body 331;

[0090] One end of the transmission cylinder body 331 abuts against the inner sleeve 312, and the transmission cylinder body 331 and the inner sleeve 312 are coaxially rotatably arranged;

[0091] A middle part in the cylinder barrel 32 protrudes to form a partition part 321, and there is a moving gap between the other end of the transmission cylinder body 331 and the partition part 321;

[0092] A buffer sliding cavity 30 is formed by enclosing between the inner wall of the outer sleeve 311, the inner sleeve 312, the transmission cylinder body 331 and the partition part 321. The ball bearing 332 is installed in the buffer sliding cavity 30. The ball bearing 332 is sleeved outside the transmission cylinder body 331, and the inside of the ball bearing 332 is connected to the transmission cylinder body 331, and the inside of the ball bearing 332 is connected to the cylinder barrel 32.

[0093] Specifically, the transmission structure 33 realizes the functions of axial floating buffering and rotational power transmission through the collaborative design of the transmission cylinder body 331 and the ball bearing 332:

[0094] As Figure 5 shown, when air is collected into the first air storage cavity 43 and air is supplied to the second air storage cavity 44, driving the cylinder barrel 32 and the seal 42 to move closer to the transmission cylinder body 331, the moving gap is reduced and the partition part 321 at the middle end inside the cylinder barrel 32 abuts against the transmission cylinder body 331, and the transmission cylinder body 331 abuts against the inner sleeve 312 again, and the axial thrust is sequentially transmitted to the transmission cylinder body 331 and the inner sleeve 312. The movement of the inner sleeve 312 drives the installation push rod 61 and the grinding and cutting terminal to move together, realizing the axial floating of the grinding and cutting terminal 5.

[0095] When the terminal driving mechanism 2 drives the outer sleeve 311 and the inner sleeve 312 to rotate together, since the transmission cylinder body 331 abuts against the inner sleeve 312 and is not connected to the piston push rod 62, the transmission cylinder body 331 is driven to rotate together, while the piston push rod 62 does not rotate; further, since the inside of the ball bearing 332 is connected to the transmission cylinder body 331 and the inside of the ball bearing 332 is connected to the cylinder barrel 32, the cylinder barrel 32 does not rotate either.

[0096] For further explanation, there is a first buffer air cavity between the side of the partition part 321 close to the rear end of the piston push rod 62 and the piston push rod 62, and the return spring 9 is arranged in the first buffer air cavity.

[0097] Specifically, as Figure 5As shown, when the piston push rod 62 is pushed by the compressed gas in the replacement air chamber 35, the piston push rod 62 will move towards the direction of the mounting push rod 61, thereby compressing the gas in the first buffer air chamber, and at the same time, the return spring 9 is compressed. In this way, the first buffer air chamber and the return spring 9 work together to absorb the impact force and reduce the rigid collision between the piston push rod 62 and the mounting push rod 61. At the same time, the change in the gas pressure in the first buffer air chamber can adjust the movement speed of the piston push rod 62 to achieve dynamic pressure compensation. When the replacement air chamber 35 exhausts and relieves pressure, the return spring 9 resumes, causing the piston push rod 62 to reset.

[0098] For further illustration, a plurality of slide rails 314 are provided inside the outer sleeve 311 along its circumferential direction, and the plurality of slide rails 314 are all arranged along the axial direction of the outer sleeve 311;

[0099] A plurality of sliders 315 are formed to protrude from the outside of the inner sleeve 312 along its circumferential direction. The plurality of sliders 315 are connected to the plurality of slide rails 314 in a one-to-one correspondence, and the inner sleeve 312 slides along the axial direction of the outer sleeve 311 through the sliders 315 and the slide rails 314.

[0100] Specifically, as Figure 4 shown, the installation cylinder body 31 adopts an inner and outer double-cylinder nested structure. On the one hand, the outer sleeve 311 forms a sliding fit with the sliders 315 of the inner sleeve 312 through the slide rails 314 to realize the flexible movement of the inner sleeve 312 along the axial direction of the outer sleeve 311; and the inner sleeve 312 abuts against the cylinder barrel 32 through the transmission structure 33 to ensure that the forward and backward movement of the cylinder barrel 32 can be transmitted to the inner sleeve 312 and the mounting push rod 61. When the cylinder barrel 32 is axially floated by air pressure, the inner sleeve 312 slides along the slide rails 314 of the outer sleeve 311 through the sliders 315, which not only maintains the continuity of rotational power transmission but also allows the mounting push rod 61 to axially displace. On the other hand, the one-to-one connection of the plurality of sliders 315 and the plurality of slide rails 314 also enables the inner sleeve 312 to realize synchronous coaxial rotation with the outer sleeve 311 under the drive of the terminal drive mechanism 2.

[0101] For further illustration, a top sleeve 10 is installed at one end of the piston push rod 62 close to the mounting push rod 61;

[0102] A second buffer air chamber is formed between one side of the first limiting portion 313 close to the top sleeve 10 and the top sleeve 10, and the return spring 9 is arranged inside the second buffer air chamber.

[0103] In the above-mentioned operation of replacing the grinding and cutting terminal 5, as Figure 4As shown, when the piston push rod 62 pushes the top sleeve 10 forward, the top sleeve 10 compresses the return spring 9 and squeezes the gas in the second buffer air chamber. The gas pressure and the spring deformation jointly absorb the impact kinetic energy. When the piston push rod 62 retracts, the return spring 9 extends reversely to push the top sleeve 10 back to its initial state.

[0104] For further illustration, at one end of the installation push rod 61 away from the piston push rod 62, a plurality of jaws 11 are installed. The plurality of jaws 11 are installed inside the inner sleeve 312 in a telescopically openable and closable manner. On the circumferential surface inside the inner shell 3, there are inclined surfaces matching the plurality of jaws 11.

[0105] Specifically, as Figure 4 shown, a plurality of jaws 11 are installed at the front end of the push rod, and the jaws 11 are in contact with the inclined surface on the inner wall of the inner sleeve 312. When the piston push rod 62 pushes the push rod forward through the elastic member 9, the jaws 11 expand outward along the inclined surface of the inner sleeve 312, and the tips of the jaws 11 release the processing shaft of the grinding and cutting terminal 5. When operating in the reverse direction, the push rod retracts, the elastic member 9 resets, and the jaws 11 retract and close along the inclined surface and tightly clamp the grinding and cutting terminal 5.

[0106] That is, the plurality of jaws 11 achieve self-centering clamping through the inclined surface self-locking structure. When replacing the tool, only the processing shaft of the grinding and cutting terminal 5 needs to be inserted and pulled out at the end of the push rod, without the need for additional screw or wrench operations, improving the replacement efficiency of the grinding and cutting terminal 5.

[0107] For further illustration, the terminal driving mechanism 2 includes a terminal driving motor 21, a belt 22, and a pulley 23;

[0108] A pulley 23 is installed on both the driving shaft of the terminal driving motor 21 and the outside of the nested cylinder. A main bearing 12 is installed between the outside of the nested cylinder and the mounting seat 1. The belt 22 is sleeved on the outer wheel surfaces of the two pulleys 23. The terminal driving motor 21 is used to drive the nested cylinder to rotate on the mounting seat 1.

[0109] As Figure 1-2 shown, the driving shaft of the terminal driving motor 21 is connected to the outside of the nested cylinder through the pulley 23 and the belt 22. At the same time, a main bearing 24 is also installed on the outside of the nested cylinder to form a transmission system on the mounting seat 1, so that the output shaft of the terminal driving motor 21 and the rotating shaft of the grinding and cutting terminal 5 on the output shaft 6 inside the nested cylinder are not on the same straight line, forming a non-coaxial transmission structure 33 to reduce structural interference.

[0110] The technical principle of the present invention has been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be construed in any way as a limitation on the protection scope of the present invention. Based on the explanations herein, those skilled in the art can readily conceive of other specific embodiments of the present invention without creative efforts, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
