Description

Technical Field

[0001] This application relates to the field of product clamping technology, specifically to a chuck and processing equipment. Background Technology

[0002] A chuck is used to hold the workpiece to be processed, ensuring that the workpiece maintains a stable position and orientation during processing. A rotary drive mechanism rotates the chuck and workpiece, thereby cooperating with the tool head to achieve engraving or cutting of the product.

[0003] In related technologies, chucks and rotary drives are typically connected by set screws. While this connection method can speed up the assembly and disassembly of the chuck and rotary drive to some extent, the reliability of set screw connections is relatively poor, especially under high torque conditions, where slippage or loosening is likely to occur. Furthermore, set screw connections are highly dependent on the assembly experience of the assembler; different tightening sequences, uniform force application, and force control can all lead to significant misalignment of the chuck and rotary drive shaft axes, thus affecting the machining accuracy of the workpiece.

[0101] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0102] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0103] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0104] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0105] This application proposes a processing equipment, which may be a laser engraving machine, a milling machine, a lathe, an industrial robot processing station, or a 3D printing composite processing equipment, and this application does not limit it.

[0106] Please refer to Figure 1In some embodiments, the processing equipment 1000 includes a processing platform 200, a tool head 300, a rotary drive 400, and a chuck 100. The processing platform 200 serves as the basic structure of the processing equipment 1000, supporting and connecting other structures within the equipment. Optionally, the processing platform 200 can also serve as a reference surface for workpiece fixation, providing positioning and stable support for the workpiece to be processed, ensuring that the workpiece's position does not shift during processing, thereby improving processing accuracy and consistency. In some feasible embodiments, the rotary drive 400 may be mounted on another base placed on the processing platform.

[0107] The machining platform refers to a general-purpose workbench that can be used for various machining methods. For example, a machining platform can be used for 3D printing, laser processing, cutting with a scalpel, and drawing with a pen, among other machining methods.

[0108] In 3D printing, the processing platform can be considered as the printing platform, which may include a heated bed, and may further include at least one of a printing panel located on the heated bed and a heated bed support for supporting the heated bed, wherein the heated bed support may elastically support the heated bed or fixedly support the heated bed and the printing panel.

[0109] Laser processing platforms may include laser pads on which the object to be laser-processed is placed. Optionally, if the processing equipment can perform both 3D printing and laser processing, the processing platform may include not only laser pads but also a heated bed, and even a printing panel. When laser processing is required, the laser pad can be placed on the heated bed; when 3D printing is required, the laser pad is removed and the printing panel is placed on the heated bed. Alternatively, the processing platform can also be a printing platform, allowing the equipment to engrave / cut the printed part while printing, or to engrave / cut the printed part on the printing platform after printing is complete.

[0110] The tool head 300 is located on one side of the machining platform 200. The tool head 300 is used for various processes such as material removal, shaping, and surface finishing of the workpiece. The type and function of the tool head 300 vary depending on the machining equipment 1000. For example, when the machining equipment 1000 is a laser engraving machine, the tool head 300 can be a laser head, which uses a laser to melt and cut the material to create intricate patterns and text on the material surface. When the machining equipment 1000 is a milling machine, the tool head 300 can be a milling cutter, which removes material and shapes the workpiece through rotary cutting, thereby forming complex shapes and contours on the workpiece surface. When the machining equipment 1000 is a lathe, the tool head 300 is a lathe tool, which is mainly used for rotary machining of the workpiece, thereby forming outer circles, inner holes, and threads on the workpiece surface.

[0111] A rotary drive 400 is mounted on the processing platform 200. The rotary drive 400 drives the chuck 100 to rotate, thereby cooperating with the tool head 300 to perform engraving or cutting on the product. The rotary drive 400 can be a motor, such as a stepper motor or servo motor, or a pneumatic motor, or any other drive device capable of providing rotational power; this application does not impose any limitations on this. The rotary drive 400 is provided with a drive shaft 410 for connecting to the chuck 100.

[0112] The chuck 100 is located on the machining platform 200 surface 311 facing the tool head 300 and is connected to the drive shaft 410 of the rotary drive 400. The chuck is used to clamp the workpiece to be machined to ensure that the workpiece can maintain a stable position and posture during the machining process.

[0113] Please refer to Figure 2 and Figure 3 In some embodiments, the chuck 100 includes a chuck base 1 and grippers 2. The chuck base 1 serves as the main structure of the chuck 100 and is used to support and connect the various component assemblies of the chuck 100. The chuck 100 is connected to the drive shaft 410 of the rotary drive 400 through the chuck base 1.

[0114] The gripper 2 is mounted on the chuck base 1 and can rotate with the chuck base 1 around the rotary drive 400. The gripper 2 is used to clamp the workpiece. The number of grippers 2 can be two, three, or four, and this application does not limit this. Exemplarily, in this application, three grippers 2 are provided and are evenly distributed at 120° on the chuck base 1. This ensures that a uniform clamping force is applied to the workpiece during the clamping process, thereby effectively preventing the workpiece from moving or deforming during processing.

[0115] To improve the versatility of the chuck 100, in some embodiments, the gripper 2 is movably disposed on the chuck base 1 and has the following relative position to the chuck base 1: Figure 2 The first position shown and as Figure 3 The second position shown is arranged radially along the chuck base 1, with the first and second positions being closer to the edge of the chuck base 1 compared to the second position. In practical applications, the operator can control the jaws 2 to move between the first and second positions according to the actual specifications of the workpiece, so that the chuck 100 can adapt to different workpiece shapes and sizes, improving the versatility of the chuck 100.

[0116] Understandably, in other embodiments, the gripper 2 may also have a third or fourth position relative to the chuck seat 1 that is different from the first and second positions, or may be infinitely adjustable (i.e., the gripper 2 may be located at any position in the radial direction of the chuck seat 1), thereby enabling the chuck 100 to better adapt to the shape, size and specifications of various parts and improve the versatility of the chuck 100.

[0117] The chuck 100 also includes a fixing member 5, which is used to lock the gripper 2 after it moves to a preset position, thereby ensuring the stability of the gripper 2 in clamping the workpiece. The fixing member 5 is used to detachably connect the gripper 2 to the chuck base 1 when the gripper 2 is in the first position or the second position, thereby ensuring the stable clamping of the workpiece by the gripper 2.

[0118] There are various ways in which the fixing member 5 can detachably connect the gripper 2 to the first position or the second position. In some embodiments, the fixing member 5 can also be a threaded member. Correspondingly, the gripper 2 and the chuck seat 1 are provided with threaded holes. When the gripper 2 slides to the first position or the second position, the operator can pass the threaded member through the threaded holes of the gripper 2 and the chuck seat 1 to fix the gripper 2 to the first position or the second position of the chuck seat 1.

[0119] In some embodiments, the fixing element can also be a magnetic element, with the jaws magnetically connected to the chuck seat. When the fixing element is a magnetic element, it can be a magnet, with magnets disposed on the chuck seat and the jaws. When the jaws move to the first position or the second position, the magnets of the jaws and the magnets of the chuck seat can attract each other, thereby fixing the jaws to the first position or the second position of the chuck seat.

[0120] The fixing element can also be an electromagnetic coil and a permanent magnet. One of the electromagnetic coil and the permanent magnet is located in the gripper, and the other is located in the chuck seat. When the gripper moves to the first position or the second position, the operator can energize the electromagnetic coil, so that the permanent magnet and the electromagnetic coil attract each other, thereby fixing the gripper in the first position or the second position of the chuck seat.

[0121] In some embodiments, the fixing member may also be at least two clamping blocks disposed at a first position and a second position. When the jaw moves to the first position and the second position, the two clamping blocks move closer to each other, thereby allowing the jaw to be fixed at the first position or the second position.

[0122] In some embodiments, the fixing member 5 may also include a snap-fit ​​member 5a, through which the gripper 2 is engaged with the chuck seat 1. Specifically, in this embodiment, the fixing member 5 includes a snap-fit ​​member 5a, one end of which is rotatably connected to the chuck seat 1, and the other end is provided with an engaging portion. The engaging portion is used to engage with the mating portion 21 of the gripper 2 to fix the gripper 2 to the chuck seat 1 when the gripper 2 moves to the first position or the second position. Compared with other connection methods, the snap-fit ​​member 5a has a faster disassembly speed, lower arrangement cost, and occupies less space in the chuck seat 1, which can effectively improve the space utilization rate of the chuck 100 for the processing equipment 1000.

[0123] Please refer to Figure 4 When the fixing member 5 is a snap-fit ​​member 5a, the structure of the snap-fit ​​part of the snap-fit ​​member 5a and the mating part 21 of the gripper 2 can be varied. In some embodiments, the snap-fit ​​part is a protrusion 51, and the mating part 21 includes a first slot 211 and a second slot 212. Compared with the second slot 212, the first slot 211 is closer to the center of the chuck 100. When the gripper 2 is in the first position, the snap-fit ​​part engages with the first slot 211; when the gripper 2 is in the second position, the snap-fit ​​part engages with the second slot 212. In this way, when the gripper 2 moves to the first position or the second position, the gripper 2 is fixed on the chuck seat 1. The setting of the first slot 211 and the second slot 212 can realize the quick disassembly and detachment of the gripper 2 on the chuck seat 1. On the other hand, the engagement of the slot and the protrusion 51 can increase the contact area between the snap-fit ​​member 5a and the gripper 2, and improve the stability of the snap-fit ​​member 5a for the snap-fit ​​connection.

[0124] Please refer to Figure 5 When the engaging part is a protrusion 51, in order to improve the stability of the connection between the engaging part and the mating part 21, in some embodiments, the angle α between the protrusion 51 and the buckle 5a is an acute angle. With the acute angle of the protrusion 51, the protrusion 51 will be tilted to a certain extent when it enters the first slot 211 or the second slot 212. This tilting makes the edge of the protrusion 51 more deeply embedded in the first slot 211 or the second slot 212 when the gripper 2 is subjected to external force (such as rotational force), thereby generating self-locking. This reduces the possibility that the engaging part and the mating part 21 will separate when the chuck 100 rotates, causing the gripper 2 to disengage from the chuck seat 1, and improves the reliability of the gripper 2 installation.

[0125] In addition to using the first and second slots, in some other embodiments, the first and second slots can be replaced with inclined slots with wedge-shaped bottom surfaces, thereby achieving stepless adjustment of the gripper on the chuck seat.

[0126] Understandably, due to the existence of processing errors, workpieces of the same shape and specifications may differ in length and size. In order to improve the stability of the gripper 2 in clamping a specific workpiece, in some embodiments, in addition to being able to make coarse adjustments to the position of the gripper 2 on the chuck seat 1, the operator can also make fine adjustments to the position of the gripper 2 according to the slight differences in the size of the workpiece after the gripper 2 is fixed.

[0127] For details, please refer to Figure 6 In this embodiment, the chuck holder 1 includes a base body 11, a movable component 12, and a driving component 13. The base body 11 is the main structure of the chuck holder 1, used to support and connect the various structural components of the chuck holder 1.

[0128] The movable member 12 is movably disposed on the base body 11 along the direction from the center to the edge of the chuck 100. In some embodiments, the base body 11 is provided with a first slide groove 111 extending along the direction from the center to the edge of the chuck 100. The movable member 12 is slidably disposed in the first slide groove 111. This ensures that the movable member 12 can move along a preset trajectory and improves the stability of the movable member 12 on the base body 11.

[0129] The gripper 2 is positioned above the movable component 12. One end of the latching member 5a is rotatably connected to the movable component 12, and the other end engages with the mating part 21 to fix the gripper 2 and the movable component 12 in place. The driving member 13 drives the movable component 12 to move. In practical applications, the operator can first manually adjust the gripper 2 to a first or second position according to the approximate shape of the workpiece, and then latch the gripper 2 and the movable component 12 using the latching member 5a. Afterward, the operator can adjust the movement of the movable component 12 using the driving member 13, and the movable component 12 drives the gripper 2 to move in a preset direction, thereby achieving a tight fit between the gripper 2 and the workpiece, reducing the fit gap 34 between the gripper 2 and the workpiece, improving the stability of the gripper 2 in holding the workpiece, reducing the swaying amplitude of the workpiece during the rotation of the chuck 100, and improving the processing accuracy of the processing equipment 1000.

[0130] Please refer to Figure 7 In some embodiments, the moving member 12 is provided with a second slide groove 122, and part of the gripper 2 extends into the second slide groove 122. The second slide groove 122 is used to guide the movement of the gripper 2 on the moving member 12, improve the smoothness of the gripper 2 sliding on the moving member 12, reduce the difficulty of adjusting the gripper 2, and improve the clamping efficiency of the chuck 100 for the workpiece.

[0131] Please refer to Figure 8To drive the moving component 12, the driving component 13 can be a motor, a cylinder, or a pneumatic motor; this application does not limit this. In some embodiments, the driving component 13 is disposed on the base body 11 and can rotate around the axis of the base body 11; the driving component 13 has a helical groove 131, and the moving component 12 has a protrusion 121 on the side facing away from the gripper 2, the protrusion 121 extending into the helical groove 131. When the driving component 13 rotates, the shape of the helical groove 131 guides the protrusion 121 to move along the helical path, thereby driving the moving component 12 to move along the direction from the center to the edge of the chuck 100, or from the edge to the center of the chuck 100. Compared with other driving methods, the helical structure is simple and occupies less space in the chuck 100, which can effectively reduce the size and manufacturing cost of the chuck 100.

[0132] To facilitate rotation of the drive component 13 by the operator, in some embodiments, the outer edge surface of the drive component 13 is provided with multiple outwardly protruding knurled structures 132. These knurled structures 132 can be outwardly protruding circular bumps 121, outwardly protruding rectangular bumps 121, or outwardly protruding cylindrical or other regular or irregular bumps 121; this application does not impose any limitations on these. The knurled structures 132 are used to increase the friction on the surface of the drive component 13, reduce the rotational resistance of the drive component 13 for the operator, lower the difficulty of rotating the drive component 13 for the operator, and improve the workpiece clamping efficiency.

[0133] To connect the chuck 100 to the rotary drive 400, the chuck base 1 typically has a shaft hole. The drive shaft 410 of the rotary drive 400 passes through the shaft hole of the chuck base 1 and is connected to the chuck base 1 by other connecting parts. Generally, to enable quick assembly and disassembly of the chuck 100 on the rotary drive 400, this connecting part is usually set as a threaded set screw. Although this connection method can speed up the assembly and disassembly of the chuck 100 and the rotary drive 400 to some extent, the reliability of the set screw connection is relatively poor, especially under high torque conditions, where it is prone to slippage or loosening.

[0134] Please refer to Figures 9 to 11 To solve the above problems, in one embodiment of this application, the chuck 100 further includes a pipe clamp structure 3 and a locking member 4, wherein the pipe clamp structure 3 includes a connecting part 31, a first clamping arm 32 and a second clamping arm 33, and at least one of the connecting part 31, the first clamping arm 32 and the second clamping arm 33 is fixedly connected to the chuck seat 1.

[0135] The first clamping arm 32, the second clamping arm 33, and the connecting part 31 form a clamping space 35. The clamping space 35 is connected to the rotating shaft hole of the chuck seat 1. The clamping space 35 is used for the drive shaft 410 of the rotary drive 400 to pass through. The drive shaft 410 can pass into the rotating shaft hole of the chuck seat 1 through the clamping space 35. The first clamping arm 32 and the second clamping arm 33 are disposed on opposite sides of the connecting portion 31. A gap 34 is formed between the end of the first clamping arm 32 away from the connecting portion 31 and the end of the second clamping arm 33 away from the connecting portion 31. A locking member 4 is disposed at the gap 34. The locking member 4 is used to adjust the size of the gap 34. When the gap 34 is reduced, the clamping space 35 is contracted, and the first clamping arm 32 and the second clamping arm 33 clamp the drive shaft 410 of the rotary drive member 400. When the gap 34 is restored, the clamping space 35 is restored, and the first clamping arm 32 and the second clamping arm 33 release the drive shaft 410 of the rotary drive member 400.

[0136] This application uses a locking element 4 to drive the first clamping arm 32 and the second clamping arm 33 to move closer or further away, thereby achieving the locking and releasing of the pipe clamp structure 3 on the output shaft of the chuck 100 drive component. In practical applications, operators can quickly disassemble and reassemble the chuck 100 on the chuck 100 drive component simply by operating the locking element 4, improving the assembly efficiency of the chuck 100 and the chuck 100 drive component. Simultaneously, because the first clamping arm 32 and the second clamping arm 33 maintain relative contact with the circumferential surface of the output shaft during the locking process, compared to other connection methods, such as set screw connections, the pipe clamp structure 3 of this application has a larger contact area with the output shaft, stronger anti-torsion performance, and less wobble of the chuck 100 relative to the output shaft when the output shaft rotates, resulting in higher machining accuracy.

[0137] The tube clamp structure 3 can be configured in various ways on the chuck seat 1. In some embodiments, the connecting part 31 can be connected to the chuck seat 1, and the first clamping arm 32 and the second clamping arm 33 can be spaced apart from the chuck seat 1. The locking member 4 can drive the tube clamp structure 3 to clamp the drive shaft 410 by moving the first clamping arm 32 and the second clamping arm 33 closer together. In some embodiments, the first clamping arm 32 or the first clamping arm 32 and the connecting part 31 can be connected to the chuck seat 1, and the locking member 4 can drive the tube clamp structure 3 to clamp the drive shaft 410 by moving the second clamping arm 33 closer to the first clamping arm 32. In other embodiments, the second clamping arm 33 or the second clamping arm 33 and the connecting part can be connected to the chuck seat 1, and the locking member 4 can drive the tube clamp structure 3 to clamp the drive shaft 410 by moving the second clamping arm 33 closer to the first clamping arm 32. This application does not limit this.

[0138] The locking element 4 can have various structures. In some embodiments, the locking element includes a bolt and a nut. One end of the bolt abuts against the first clamping arm, and the other end passes through the first clamping arm, the gap, and the second clamping arm, and engages with the nut. In practical applications, the operator can tighten the nut to drive the second clamping arm towards the first clamping arm, reducing the gap and clamping space, thereby driving the first and second clamping arms to grip the drive shaft. Conversely, the operator can also loosen the nut to relieve the pressure of the nut on the second clamping arm, allowing the second clamping arm to move away from the first clamping arm under its own elastic force, restoring the gap and clamping space, and releasing the drive shaft.

[0139] Please refer to Figure 11 In some embodiments, the locking member 4 may also include a pressure block 41 and a first connecting shaft 42, the first connecting shaft 42 passing through the first clamping arm 32, the gap 34, and the second clamping arm 33 in sequence; the first connecting shaft 42 has a first end extending out of the first clamping arm 32; the pressure block 41 is disposed at the first end, and the pressure block 41 is used to drive the first connecting shaft 42 to move along the direction from the second clamping arm 33 to the first clamping arm 32, so as to drive the second clamping arm 33 to move towards the side of the first clamping arm 32, thereby reducing the size of the gap 34 and the clamping space 35, and thus achieving the clamping of the first clamping arm 32 and the second clamping arm 33 on the drive shaft 410. Similarly, the pressure block 41 can also drive the first connecting shaft 42 to move along the direction from the first clamping arm 32 to the second clamping arm 33, thereby restoring the gap 34 and the clamping space 35 and releasing the drive shaft 410.

[0140] The pressure block 41 can move laterally to drive the first connecting shaft 42, or it can move longitudinally to drive the first connecting shaft 42, or it can rotate to drive the first connecting shaft 42; this application does not limit this. In some embodiments, the locking member 4 further includes a second connecting shaft 43, which is connected to the first end of the first connecting shaft 42; the pressure block 41 is connected to the second connecting shaft 43 and can rotate about the axis of the second connecting shaft 43 to contact or separate from the first clamping arm 32. Figure 9 As shown, when the pressure block 41 moves around the second connecting shaft 43 towards the first clamping arm 32, the pressure block 41 abuts against the first clamping arm 32, driving the first connecting shaft 42 and the second clamping arm 33 to move towards the first clamping arm 32, thus reducing the gap 34 and the clamping space 35, thereby achieving a tight grip on the drive shaft 410. Figure 10 As shown, when the pressure block 41 moves away from the first clamping arm 32 around the second connecting shaft 43, the pressure block 41 separates from the first clamping arm 32, and drives the first connecting shaft 42 and the second clamping arm 33 to move away from the first clamping arm 32. The gap 34 and the clamping space 35 are restored, thereby releasing the drive shaft 410.

[0141] Compared to horizontal movement, the rotational movement of the pressure block 41 has several advantages. First, it requires less space, reducing the space occupied by the pressure block 41 and improving the adaptability of the chuck 100 in confined spaces. Second, the rotational movement ensures a good fit between the pressure block 41 and the first clamping arm 32. This fit not only enhances the reliability of the locking member 4 in locking the first and second clamping arms 32 and 33, but also reduces slippage or displacement caused by poor contact. Third, the rotational setting reduces the torque of the pressure block 41, lowering the force required during operation, reducing the difficulty for the operator in locking the first and second clamping arms 32 and 33, and improving the assembly efficiency of the chuck 100 and the drive shaft 410.

[0142] To prevent the pressure block 41 from moving away from the first clamping arm 32 under the centrifugal force during the rotation of the chuck 100, which could cause the drive shaft 410 to disengage from the pipe clamp structure 3, the pressure block 41 needs to be locked when it reaches the locked state.

[0143] There are various ways to lock the pressure block 41. In some embodiments, a buckle can be provided on the pressure block 41. When the pressure block 41 approaches the first clamping arm 32, the buckle structure on the pressure block 41 engages with the buckle structure of the first clamping arm 32, thereby locking the pressure block 41 onto the first clamping arm 32. This reduces the possibility of the pressure block 41 separating from the first clamping arm 32 during the rotation of the chuck 100, and improves the locking reliability of the locking member 4 on the pipe clamp structure 3.

[0144] In some other embodiments, a cam structure may also be used to achieve self-locking of the pressure block's rotation. For details, please refer to... Figure 12 In this embodiment, the pressure block 41 is provided with a mounting hole 414, and the second connecting shaft 43 is disposed within the mounting hole 414, with the axis of the second connecting shaft 43 spaced apart from the axis of the mounting hole 414. The offset setting of the axis of the second connecting shaft 43 and the mounting hole 414 allows a "cam structure" to be formed between the pressure block 41 and the second connecting shaft 43. Under this structure, when the pressure block 41 rotates towards the locked state, the pressure block 41 can pass the "geometric dead point" of the cam structure and form a self-locking mechanism. In this way, the possibility of the pressure block 41 unlocking due to vibration when the chuck 100 rotates is reduced, and the reliability of the locking member 4 locking the pipe clamp structure 3 is improved. Moreover, compared with setting a buckle, the structure of offset setting of the axis of the second connecting shaft 43 and the mounting hole 414 is simpler, has lower manufacturing cost, and occupies less space in the chuck 100, which can effectively reduce the subsequent maintenance cost of the chuck 100 and improve the reliability of the installation of the chuck 100 and the drive shaft 410.

[0145] Please refer to Figure 13 and Figure 14To improve the stability of the connection between the pressure block 41 and the first clamping arm 32, in some embodiments, a platform surface 311 is provided on the outer side of the connecting portion 31; the pressure block 41 includes an arc segment portion 411 and a flat segment portion 412 connected together; when the locking member 4 is in the locked state, the arc segment portion 411 is in contact with the outer wall surface of the first clamping arm 32; the flat segment portion 412 is in contact with the platform surface 311. The platform surface 311 can reduce the stacking height of the pressure block 41 and the pipe clamp structure 3 when the pressure block 41 is in the locked state, thereby improving the space utilization rate of the chuck 100 for the processing equipment 1000. On the other hand, when the chuck 100 rotates at high speed, the pressure block 41 may have an axial displacement tendency due to centrifugal force. If only the arc segment portion 411 is used to contact the first clamping arm 32, its curved surface contact may slip due to slight displacement under vibration environment, reducing the self-locking effect of the pipe clamp structure 3 on the pressure block 41. The planar contact between the flat section 412 and the platform surface 311 can provide axial support reaction force for the pressure block 41, counteracting the axial displacement tendency of the pressure block 41 itself during the locking process, thereby reducing the possibility of the pressure block 41 being unlocked due to vibration when the chuck 100 rotates, and improving the reliability of the locking member 4 in locking the pipe clamp structure 3.

[0146] During rotation, the pressure block 41 will wear against the first clamping arm 32. When the pressure block 41 and the first clamping arm 32 wear excessively, the contact between the pressure block 41 and the first clamping arm 32 may no longer be tight, which will affect the stability and reliability of the pipe clamp structure 3 in locking the drive shaft 410.

[0147] Please refer to Figure 15 and Figure 16 To address the aforementioned issues, in some embodiments, the locking member 4 further includes a gasket 44, which is disposed between the pressure block 41 and the first clamping arm 32. This prevents direct contact between the pressure block 41 and the first clamping arm 32, thus avoiding wear on the first clamping arm 32 and improving the service life of the pipe clamp structure 3. Specifically, in this embodiment, the outer wall of the first clamping arm 32 is recessed 321 on the side facing the clamping space 35; the locking member 4 further includes a second connecting shaft 43 and a gasket 44, with the second connecting shaft 43 connected to the first connecting shaft 42; the pressure block 41 further includes a hinge portion 413, which is disposed on the side of the arc segment 411 away from the flat segment 412, and the connecting portion 31 is connected to the second connecting shaft 43; the connecting portion 31 is accommodated within the recess 321; the gasket 44 is sleeved on the outside of the first connecting shaft 42 and is located between the connecting portion 31 and the outer wall surface of the first clamping arm 32. Thus, when the pressure block 41 and the gasket 44 wear out, causing the pressure block 41 to be unable to fit tightly with the first clamping arm 32, thereby affecting the locking effect of the pressure block 41 on the pipe clamp structure 3, the operator only needs to replace the detachable pressure block 41 and the gasket 44 to restore the clamping state of the pressure block 41 and the first clamping arm 32, maintain the stability of the entire clamping system, and extend the service life of the pipe clamp structure 3.

[0148] Please refer to Figure 17 To accommodate the clamping block 41, in some embodiments, the thickness of the first clamping arm 32 is less than the thickness of the second clamping arm 33 along the radial direction of the chuck 100. This arrangement serves two purposes: firstly, since the first clamping arm 32 needs to engage with the clamping block 41, reducing the thickness of the first clamping arm 32 reduces the overall thickness of the pipe clamp structure 3 and the clamping block 41 after they engage, improving the space utilization of the chuck 100 within the processing equipment 1000. Secondly, reducing the thickness of the first clamping arm 32 reduces the weight on one side of the first clamping arm 32, reducing the impact of the clamping block 41 on the dynamic balance of the chuck 100 when positioned on the first clamping arm 32, reducing the relative wobble amplitude between the chuck 100 and the output shaft during rotation, and improving the processing accuracy of the processing equipment 1000.

[0149] To reduce the difficulty of the locking member 4 driving the first clamping arm 32 and the second clamping arm 33 to move closer or further apart, in some embodiments, the connecting part 31 is provided with a relief groove 312 on the side facing the clamping space 35. The relief groove 312 can provide relief for the second clamping arm 33 to move towards the first clamping arm 32, thereby reducing the difficulty of the second clamping arm 33 approaching the first clamping arm 32 without reducing the overall thickness of the pipe clamp structure 3, and reducing the difficulty of the locking member 4 locking the pipe clamp structure 3.

[0150] It should be noted that the above-described embodiments of the locking mechanism are all based on the first clamping arm being connected to the chuck seat, the second clamping arm being spaced apart from the chuck seat, and the pressure block being located on one side of the first clamping arm. In other possible embodiments of this application, the second clamping arm may be fixedly connected to the chuck seat, and the first clamping arm may be spaced apart from the chuck seat. In this case, the pressure block is located on one side of the second clamping arm. When the pressure block is pressed against the second clamping arm, it can drive the first connecting shaft and the first clamping arm to move towards the second clamping arm, thereby clamping the drive shaft. Alternatively, the pressure block can move away from the second clamping arm, thereby driving the first connecting shaft and the first clamping arm to move away from the second clamping arm, thereby releasing the drive shaft.

[0151] Simultaneously, when the locking element is in the locked state, the arc-shaped portion of the pressure block is in contact with the outer wall surface of the second clamping arm; the flat portion is in contact with the platform surface. Along the radial direction of the chuck, the thickness of the second clamping arm can also be less than the thickness of the first clamping arm, thereby maintaining the stability of the chuck's dynamic balance. Further details are omitted here.

[0152] In the description of the embodiments of this application, it should be noted that the orientation or positional relationship of the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and other indicators are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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 application.

[0153] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
