Description

Technical Field

[0001] This utility model relates to the field of post-processing technology for artificial stone slabs, and in particular to a floating power head for processing artificial stone slabs. Background Technology

[0002] In the stone processing industry, especially in the post-processing of artificial stone countertops such as kitchen sinks, it is often necessary to create various functional grooves and openings inside the slabs. These include basin holes for embedding sinks, stove holes for installing gas stoves, and faucet holes for fixing faucets. Furthermore, the outer edges of the slabs need to be finely processed according to design requirements, such as cutting curves, bevels, or irregular contours for specially shaped countertops. To ensure a smooth transition between the groove edges and the installed components (such as sinks), the edges of the basin holes or stove holes also need to be rounded or chamfered. During processing, the artificial stone slabs are usually fixed horizontally on a workbench, and a power head completes the cutting operation according to a preset path and dimensions.

[0003] Current mainstream drive solutions mostly employ multi-degree-of-freedom robotic arms or XYZ three-dimensional linear drive systems. Their mechanical structures are based on gantry frames, column-beam combinations, or slide rail-slide rail units, representing common industry technologies. However, existing technologies have the following limitations:

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

[0005] (2) Inefficient replacement of grinding and cutting terminals: The grinding and cutting terminals (such as cutting heads and grinding heads) mounted on the power head need to be manually disassembled and replaced, which makes it difficult to meet the needs of continuous multi-process processing.

[0006] (3) Structural interference problem is prominent: When performing internal finishing operations on the basin / furnace holes, the excessive size of the power head directly affects the range of movement. Most existing power heads use a three-jaw clamp with a universal interface to fix the grinding and cutting end, and the drive motor and the power head shaft are designed to be coaxial, resulting in redundant overall axial dimensions and limiting the operational flexibility in confined spaces. Utility Model Content

[0007] The purpose of this invention is to propose a floating power head for processing artificial stone slabs, so as to solve the technical problems of limited motion dimensions, inefficient replacement of grinding and cutting ends, and prominent structural interference problems in existing artificial stone slab power heads.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] A floating power head for processing artificial stone slabs includes a mounting base, a terminal drive mechanism, a nested cylinder, and a grinding and cutting end.

[0010] The mounting base is equipped with the terminal drive mechanism, which drives the grinding and cutting terminal to rotate for processing in a non-coaxial drive manner;

[0011] The nested cylinder includes an outer shell, an inner shell, and an output shaft;

[0012] The outer shell is connected to a floating air pipe. The floating air pipe drives the inner shell and the output shaft to float along the axial direction of the outer shell by pneumatically extending or retracting air into or out of the outer shell.

[0013] The inner shell is connected to a replacement air pipe. The replacement air pipe, by supplying or depriving air to the inner shell and in conjunction with the action of a return spring, drives the output shaft to achieve the disassembly or installation of the grinding and cutting terminal.

[0014] Preferably, the housing includes a cylinder liner and a seal;

[0015] The cylinder liner is fixedly installed on the mounting base. The cylinder liner is sleeved on the outside of the inner shell, and a gas-carrying space is left between the inner wall of the cylinder liner and the outside of the inner shell. The sealing element is provided in the gas-carrying space along its circumference on the outside of the inner shell. The sealing element divides the gas-carrying space into a first gas-carrying chamber and a second gas-carrying chamber.

[0016] The cylinder liner has floating air pipes that are respectively connected to the first air chamber and the second air chamber. The two floating air pipes are used to supply air to the first air chamber and the second air chamber or to draw air from them, so as to push the inner shell and the output shaft to move together along the axial direction of the cylinder liner in a pneumatic manner, thereby realizing the floating of the inner shell and the output shaft in the axial direction.

[0017] Preferably, the inner shell includes a mounting cylinder and a cylinder barrel;

[0018] The mounting cylinder includes an outer sleeve and an inner sleeve;

[0019] The output shaft includes a mounting rod and a piston rod;

[0021] The cylinder and the inner sleeve are connected by a transmission structure. The cylinder sleeve is fitted on the outside of the cylinder. The cylinder can move axially relative to the cylinder sleeve. Combined with the transmission action of the transmission structure, both the inner sleeve and the mounting push rod can move axially relative to the outer sleeve.

[0022] The piston rod is movably mounted inside the cylinder. The piston rod can move axially relative to the cylinder. The piston rod and the mounting rod are coaxially arranged. The return spring is installed circumferentially on both the piston rod and the mounting rod.

[0023] The cylinder barrel is sealed to a cylinder rear cover at the end away from the inner sleeve. A replacement air chamber is provided between the inside of the cylinder rear cover and the mounting push rod. The replacement air chamber is connected to the replacement air pipe.

[0024] The replacement air tube is used to supply or withdraw air to the replacement air chamber. It is pneumatically driven to sequentially push or retract the piston rod and the mounting rod, and in conjunction with the action of the return spring, to realize the disassembly or installation of the grinding and cutting terminal.

[0025] Preferably, the inner sleeve has a first limiting part protruding from the middle, and the mounting rod has a second limiting part protruding from the outer peripheral surface. The first limiting part is located close to the outer shell, and the second limiting part is located away from the outer shell.

[0026] When the inner sleeve moves away from the outer shell, the first limiting part and the second limiting part abut against each other, causing the inner sleeve and the mounting rod to move together;

[0027] When the mounting rod moves away from the housing, the first limiting part and the second limiting part move away from each other, allowing the mounting rod to move independently.

[0028] Preferably, the transmission structure includes a transmission cylinder and a ball bearing;

[0029] The transmission cylinder is sleeved outside the piston rod, and the transmission cylinder is not connected to the piston rod. The piston rod can move axially relative to the transmission cylinder.

[0030] One end of the transmission cylinder abuts against the inner sleeve, and the transmission cylinder and the inner sleeve are coaxially rotatable.

[0031] The middle part of the cylinder protrudes to form a partition, and the other end of the transmission cylinder has a moving gap with the partition;

[0032] The inner wall of the outer sleeve, the inner sleeve, the transmission cylinder, and the partition form a buffer sliding cavity. The ball bearing is installed in the buffer sliding cavity. The ball bearing is sleeved on the outside of the transmission cylinder, and the inside of the ball bearing is connected to the transmission cylinder and the inside of the ball bearing is connected to the cylinder.

[0033] Preferably, a first buffer air chamber is provided between the side of the separator near the rear end of the piston rod and the piston rod, and the first buffer air chamber contains the return spring.

[0034] Preferably, the outer sleeve has multiple slide rails arranged along its circumferential direction inside, and the multiple slide rails are all arranged along the axial direction of the outer sleeve;

[0035] The outer side of the inner sleeve protrudes in a circumferential direction to form multiple sliders, and the multiple sliders are connected to the multiple slide rails in a one-to-one correspondence.

[0036] Preferably, a top sleeve is installed at one end of the piston rod near the mounting rod;

[0037] A second buffer air chamber is formed between the first limiting part and the top sleeve on the side near the top sleeve, and the reset spring is built into the second buffer air chamber.

[0038] Preferably, a plurality of grippers are installed at the end of the mounting rod away from the piston rod. The plurality of grippers are retractably and openably installed inside the inner sleeve. The circumferential surface inside the inner shell is provided with an inclined surface that matches the plurality of grippers.

[0039] Preferably, the terminal drive mechanism includes a terminal drive motor, a belt, and a pulley;

[0040] Both the drive shaft of the terminal drive motor and the outside of the nested cylinder are equipped with pulleys. A main bearing is installed between the outside of the nested cylinder and the mounting base. The pulleys are sleeved on the outer surfaces of the two pulleys. The terminal drive motor is used to drive the nested cylinder to rotate on the mounting base.

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

[0042] 1. Overcoming motion dimension limitations to achieve composite machining: Traditional drive mechanisms only support linear motion in a single direction, while this solution endows the grinding terminal with axial adaptive capability. Combining the terminal drive mechanism and the rotary transmission of the grinding terminal, it can complete the machining of rectangular, irregularly shaped holes and grooves, as well as curved surfaces with higher precision. For example, in the high-precision machining of basin holes, the grinding terminal can, based on a multi-degree-of-freedom robotic arm or an XYZ three-dimensional linear drive system, finely adjust the axial feed depth through the outer shell, avoiding the motion blind spots caused by the excessive size of the power head in traditional solutions.

[0043] 2. High-efficiency tool changing, supporting multi-process integration: Utilizing pneumatic pressure combined with a return spring, the time for changing grinding and cutting ends is significantly shortened, greatly improving processing efficiency. Simultaneously, the same power head can be adapted to various grinding and cutting ends such as cutting, grinding, and chamfering, meeting the needs of the entire process, including table opening, edge trimming, and surface polishing, reducing equipment downtime.

[0044] 3. Compact structure, eliminating interference risks: The terminal drive mechanism and the grinding terminal are driven in a non-coaxial manner, forming a non-coaxial layout. Compared with the traditional coaxial motor design, the overall axial dimension is significantly reduced. Moreover, the slight axial floating of the housing further compresses the axial space requirements of the tool operation, enabling the grinding terminal to perform high-precision finishing of the internal areas of the basin hole / furnace hole.

Detailed Implementation

[0051] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0052] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0053] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0054] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] A floating power head for processing artificial stone slabs includes 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 equipped with the terminal drive mechanism 2, which drives the grinding and cutting terminal 5 to rotate for processing in a non-coaxial drive manner.

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

[0058] The outer shell 4 is connected to a floating air pipe 7. 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 by pneumatically opening or closing air to the outer shell 4.

[0059] The inner shell 3 is connected to a replacement air pipe 8. The replacement air pipe 8, by supplying or depriving air to the inner shell 3 and in conjunction with the action of the return spring 9, drives the output shaft 6 to realize the disassembly or installation of the grinding and cutting terminal 5.

[0060] like Figure 1-2As shown, this floating power head achieves axial floating functionality through a unique nested cylinder design. The floating air pipe 7 drives the inner shell 3 and output shaft 6 to float axially via pneumatic retraction and extension. This floating function, combined with the rotational motion of the terminal drive mechanism, enables the power head to achieve multi-directional composite motion during the processing of artificial stone slabs. For example, when processing rectangular basin holes, the power head can not only achieve large-amplitude linear motion in the transverse or longitudinal direction by mounting the mounting base 1 on a multi-degree-of-freedom robotic arm or an XYZ three-dimensional linear drive system, but also perform small-amplitude floating adjustments axially, thereby better refining the processing of the slabs and breaking through the limitation of traditional drive mechanisms that only support linear motion in a single direction.

[0061] Meanwhile, the replacement air pipe 8 inside the inner shell 3, through air supply and de-airing, combined with the action of the return spring 9, enables the automatic disassembly or installation of the grinding and cutting terminal. 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 separate the grinding and cutting terminal from the power head; after replacement, the replacement air pipe 8 de-airs, and under the action of the return spring 9, the output shaft 6 returns to its original position, firmly installing the new grinding and cutting terminal onto the power head. This process reduces manual intervention, greatly improves the efficiency of grinding and cutting terminal replacement, and meets the needs of multi-process continuous processing.

[0062] Furthermore, the terminal drive mechanism adopts a non-coaxial drive form, such as a motor, belt, and pulley to drive the grinding terminal to rotate. This design ensures that the drive shaft of the terminal drive mechanism and the power head rotation shaft are not on the same horizontal plane, forming a non-coaxial layout, which effectively reduces the overall axial dimension of the power head. When performing internal finishing operations on pot holes / furnace holes, the smaller power head size allows for flexible movement in confined spaces, avoiding structural interference problems and improving operational flexibility.

[0063] In summary, one of the technical solutions presented in this paper has the following beneficial effects:

[0064] 1. Overcoming motion dimension limitations to achieve composite machining: Traditional drive mechanisms only support linear motion in a single direction, while this solution endows the grinding terminal 5 with axial adaptive capability. Combined with the rotary transmission of the terminal drive mechanism 2 and the grinding terminal 5, it can complete the machining of rectangular, irregularly shaped holes and grooves, as well as curved surfaces with higher precision. For example, in the high-precision machining of basin holes, the grinding terminal 5 can, based on a multi-degree-of-freedom robotic arm or an XYZ three-dimensional linear drive system, finely adjust the axial feed depth through the outer shell 4, avoiding the motion blind spots caused by the excessive size of the power head in traditional solutions.

[0065] 2. High-efficiency tool changing, supporting multi-process integration: Utilizing pneumatic pressure combined with the return spring 9, the replacement time of the grinding and cutting terminal 5 is significantly shortened, greatly improving processing efficiency. At the same time, the same power head can be adapted to various grinding and cutting terminals 5 such as cutting, grinding, and chamfering, meeting the needs of the entire process such as table opening, edge trimming, and surface polishing, reducing equipment downtime.

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

[0067] To further explain, the outer casing 4 includes a cylinder liner 41 and a seal 42;

[0068] The cylinder liner 41 is fixedly installed on the mounting base 1. The cylinder liner 41 is sleeved on the outside of the inner shell 3, and a gas-carrying space is left between the inner wall of the cylinder liner 41 and the outside of the inner shell 3. The outer side of the cylinder barrel 32 is provided with the sealing element 42 in the gas-carrying space along the circumference of the inner shell 3. The sealing element 42 divides the gas-carrying space into a first gas-carrying chamber 43 and a second gas-carrying chamber 44.

[0069] The cylinder liner 41 is provided with floating air pipes 7 that are respectively connected to the first air chamber 43 and the second air chamber 44. The two floating air pipes 7 are respectively used to supply air to the first air chamber 43 and the second air chamber 44, so as to push the inner shell 3 and the output shaft 6 to move together along the axial direction of the cylinder liner 41 in a pneumatic manner, thereby realizing the floating of the inner shell 3 and the output shaft 6 in the axial direction.

[0070] The outer casing 4 achieves axial adaptive floating of the grinding terminal 5 through dual-chamber air pressure drive and linkage with the sealing element 42. The specific process is as follows:

[0071] like Figure 5 As shown, when the floating air pipe 7 connected to the first air chamber 43 supplies air to it, and the floating air pipe 7 connected to the second air chamber 44 supplies air to it, the gas pressure pushes the sealing element 42 along the inner wall of the cylinder liner 41 toward the second air chamber 44, compressing the volume of the second air chamber 44; when the floating air pipe 7 connected to the second air chamber 44 supplies air to it, and the floating air pipe 7 connected to the first air chamber 43 supplies air to it, the gas pressure pushes the sealing element 42 along the inner wall of the cylinder liner 41 toward the first air chamber 43, compressing the volume of the first air chamber 43. The movement of the sealing element 42 forces the connected inner shell 3 and output shaft 6 to move axially relative to the cylinder liner 41. At the same time, the axial displacement range of the grinding terminal 5 connected to the output shaft 6 can be precisely controlled by controlling the air pressure range of the two floating air pipes 7.

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

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

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

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

[0076] The cylinder 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 32. The cylinder 32 can move axially relative to the cylinder sleeve 41. Combined with the transmission action of the transmission structure 33, both the inner sleeve 312 and the mounting rod 61 can move axially relative to the outer sleeve 311.

[0077] The piston rod 62 is movably mounted inside the cylinder 32. The piston rod 62 can move axially relative to the cylinder 32. The piston rod 62 and the mounting rod 61 are coaxially arranged. The return spring 9 is installed circumferentially on both the piston rod 62 and the mounting rod 61.

[0078] The cylinder barrel 32 is sealed to a cylinder rear cover 34 at the end away from the inner sleeve 312. A replacement air chamber 35 is provided between the inside of the cylinder rear cover 34 and the mounting push rod 61. The replacement air chamber 35 is connected to the replacement air pipe 8.

[0079] The replacement air pipe 8 is used to supply or withdraw air to the replacement air chamber 35. In a pneumatically driven manner, it sequentially pushes or retracts the piston rod 62 and the mounting rod 61, and in conjunction with the return spring 9, realizes the disassembly or installation of the grinding and cutting terminal 5.

[0080] Specifically, by replacing manual operation with pneumatic drive, the replacement time is significantly reduced. 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 rod 62 to move axially along the cylinder 32. Since the piston rod 62 and the mounting rod 61 are coaxially arranged, the piston rod 62 pushes the mounting rod 61 to move axially along the mounting cylinder 31 until one end of the mounting rod 61 is completely exposed outside the mounting cylinder 31, facilitating the replacement of the grinding terminal 5. After replacement, the replacement air chamber 35 is depressurized and the piston rod 62 and the mounting rod 61 are reset by the action of the return spring 9, thus completing the replacement of the grinding terminal 5.

[0082] To further explain, the inner sleeve 312 has a protrusion at the middle to form a first limiting part 313, and the mounting rod 61 has a protrusion on its outer peripheral surface to form a second limiting part 611. The first limiting part 313 is located close to the outer shell 4, and the second limiting part 611 is located away from the outer shell 4.

[0083] When the inner sleeve 312 moves away from the outer shell 4, the first limiting part 313 and the second limiting part 611 abut against each other, causing the inner sleeve 312 and the mounting rod 61 to move together.

[0084] When the mounting rod 61 moves away from the end of the housing 4, the first limiting part 313 and the second limiting part 611 move away from each other, allowing the mounting rod 61 to move independently.

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

[0086] like Figure 2 and Figure 4 As shown, when the cylinder 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. The contact between the first limiting part 313 and the second limiting part 611 jointly controls the axial displacement range of the mounting push rod 61 and the grinding end 5.

[0087] When installation and disassembly are required, the mounting rod 61 receives the thrust of the piston rod 62 and moves axially relative to the inner sleeve 312. The first limiting part 313 separates from the second limiting part 611, allowing the mounting rod 61 to extend independently out of the inner sleeve 312. This exposes the quick-release interface on the mounting rod 61 during replacement, facilitating the replacement of the grinding terminal 5. After the thrust of the piston rod 62 is released, the return spring 9 enables rapid retraction and locking of the grinding terminal 5.

[0088] To further explain, the transmission structure 33 includes a transmission cylinder 331 and a ball bearing 332;

[0089] The transmission cylinder 331 is sleeved on the outside of the piston rod 62, and the transmission cylinder 331 is not connected to the piston rod 62. The piston rod 62 can move axially relative to the transmission cylinder 331.

[0090] One end of the transmission cylinder 331 abuts against the inner sleeve 312, and the transmission cylinder 331 and the inner sleeve 312 are coaxially rotatable.

[0091] The middle part of the cylinder 32 protrudes to form a partition 321, and the other end of the transmission cylinder 331 has a moving gap with the partition 321.

[0092] The inner wall of the outer sleeve 311, together with the inner sleeve 312, the transmission cylinder 331, and the partition 321, forms a buffer sliding cavity 30. The ball bearing 332 is installed in the buffer sliding cavity 30. The ball bearing 332 is sleeved on the outside of the transmission cylinder 331, and the inside of the ball bearing 332 is connected to the transmission cylinder 331. The inside of the ball bearing 332 is also connected to the cylinder 32.

[0093] Specifically, the transmission structure 33 achieves axial floating buffering and rotational power transmission functions through the coordinated design of the transmission cylinder 331 and the ball bearing 332.

[0094] like Figure 5 As shown, when air is drawn into the first air chamber 43 and air is introduced into the second air chamber 44, the cylinder 32 and the seal 42 move closer to the transmission cylinder 331. The moving gap is reduced and the partition 321 at the middle of the cylinder 32 abuts against the transmission cylinder 331. The transmission cylinder 331 abuts against the inner sleeve 312, and the axial thrust is transmitted to the transmission cylinder 331 and the inner sleeve 312 in sequence. The movement of the inner sleeve 312 drives the mounting rod 61 and the grinding end to move together, realizing the axial floating of the grinding end 5.

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

[0096] To further explain, a first buffer air chamber is provided between the partition 321 and the piston rod 62 on the side near the rear end of the piston rod 62, and the return spring 9 is built into the first buffer air chamber.

[0097] Specifically, such as Figure 5As shown, when the piston rod 62 is pushed by the compressed gas in the replacement chamber 35, the piston rod 62 moves towards the mounting rod 61, thereby compressing the gas in the first buffer chamber, and simultaneously compressing the return spring 9. In this way, the first buffer chamber and the return spring 9 work together to absorb the impact force and reduce the rigid collision between the piston rod 62 and the mounting rod 61. At the same time, the change in gas pressure in the first buffer chamber can adjust the movement speed of the piston rod 62, achieving dynamic pressure compensation. When the replacement chamber 35 is depressurized, the return spring 9 returns to its original position, causing the piston rod 62 to return to its original position.

[0098] To further explain, the outer sleeve 311 has multiple slide rails 314 arranged along its circumferential direction inside, and the multiple slide rails 314 are all arranged along the axial direction of the outer sleeve 311.

[0099] The inner sleeve 312 has multiple sliders 315 protruding outward along its circumferential direction. The multiple sliders 315 and the multiple slide rails 314 are connected in a one-to-one correspondence. 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, such as Figure 4 As shown, the mounting cylinder 31 adopts an inner and outer double-cylinder nested structure. On the one hand, the outer cylinder 311 forms a sliding engagement with the slider 315 of the inner cylinder 312 through the slide rail 314, realizing the flexible movement of the inner cylinder 312 along the axial direction of the outer cylinder 311. Moreover, the inner cylinder 312 abuts against the cylinder 32 through the transmission structure 33, ensuring that the forward and backward movement of the cylinder 32 can be transmitted to the inner cylinder 312 and the mounting push rod 61. When the cylinder 32 floats axially driven by air pressure, the inner cylinder 312 slides along the slide rail 314 of the outer cylinder 311 through the slider 315, maintaining the continuity of rotational power transmission and allowing the mounting push rod 61 to move axially. On the other hand, the one-to-one connection of multiple sliders 315 and multiple slide rails 314 enables the inner cylinder 312 and the outer cylinder 311 to rotate synchronously and coaxially under the drive of the terminal drive mechanism 2.

[0101] To further explain, a top sleeve 10 is installed at one end of the piston rod 62 near the mounting rod 61;

[0102] The first limiting part 313 forms a second buffer air cavity between the side of the first limiting part 313 near the top sleeve 10 and the top sleeve 10, and the second buffer air cavity contains the reset spring 9.

[0103] Following the above operation of replacing the grinding and cutting terminal 5, as follows: Figure 4As shown, when the piston 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 chamber. The gas pressure and spring deformation together absorb the impact kinetic energy. When the piston rod 62 retracts, the return spring 9 extends in the opposite direction to push the top sleeve 10 back to its initial state.

[0104] To further explain, a plurality of grippers 11 are installed at the end of the mounting rod 61 away from the piston rod 62. The plurality of grippers 11 are retractably and openably installed inside the inner sleeve 312. The inner shell 3 has an inclined surface on its inner circumferential surface that matches the plurality of grippers 11.

[0105] Specifically, such as Figure 4 As shown, multiple grippers 11 are installed at the front end of the push rod, and the grippers 11 contact the inclined surface of 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 grippers 11 expand outward along the inclined surface of the inner sleeve 312, and the tips of the grippers 11 release the processing axis of the grinding terminal 5; in the reverse operation, the push rod retracts, the elastic member 9 resets, and the grippers 11 retract along the inclined surface to close and tightly clamp the grinding terminal 5.

[0106] That is, multiple grippers 11 achieve self-centering clamping through a sloping self-locking structure. When changing tools, it is only necessary to insert or remove the processing shaft of the grinding terminal 5 to the end of the push rod, without the need for additional screws or wrenches, thus improving the replacement efficiency of the grinding terminal 5.

[0107] To further explain, the terminal drive mechanism 2 includes a terminal drive motor 21, a belt 22, and a pulley 23;

[0108] Both the drive shaft of the terminal drive motor 21 and the outside of the nested cylinder are equipped with pulleys 23. A main bearing 12 is installed between the outside of the nested cylinder and the mounting base 1. The pulleys 23 are sleeved on the outer surfaces of the two pulleys 23. The terminal drive motor 21 is used to drive the nested cylinder to rotate on the mounting base 1.

[0109] like Figure 1-2 As shown, the drive shaft of the terminal drive motor 21 is connected to the outside of the nested cylinder through pulley 23 and belt 22. At the same time, a main bearing 24 is also installed on the outside of the nested cylinder, forming a transmission system on the mounting base 1. This ensures that the output shaft of the terminal drive motor 21 and the rotation shaft of the grinding 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, reducing structural interference.

[0110] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
