[0062] This utility model proposes a clamping device 100.

[0063] Please see Figure 1 and Figure 3In one embodiment of the present invention, the clamping device 100 includes a clamping assembly 10 and a positioning assembly 20. The clamping assembly 10 includes a base 11 and a pressing member 12. The base 11 is provided with a material-carrying surface 1111. The pressing member 12 is disposed opposite to the material-carrying surface 1111 and can be close to or away from the material-carrying surface 1111. The positioning assembly 20 includes a blocking member 21 connected to the base 11. Part of the structure of the blocking member 21 protrudes from the material-carrying surface 1111 toward the pressing member 12.

[0064] The clamping device 100 proposed in this application embodiment can be used in processing equipment for clamping workpieces; wherein, the processing equipment can be a laser processing equipment that uses laser to perform at least one laser processing operation such as welding, cutting, engraving and cleaning, or it can be an inkjet printing equipment or a machining equipment that uses cutting tools for processing, etc.

[0065] The clamping device 100 includes a clamping assembly 10 for clamping workpieces and a positioning assembly 20 for positioning workpieces. The clamping assembly 10 includes a base 11 and a pressure member 12. The base 11 serves as the mounting foundation for the clamping assembly 10 and is provided with a loading surface 1111 for supporting the workpiece. The pressure member 12 is disposed opposite to the loading surface 1111 along a first direction X, and the pressure member 12 can move closer to or further away from the loading surface 1111 along the first direction X. A clamping space for clamping the workpiece is formed between the pressure member 12 and the loading surface 1111. Optionally, the first direction X can be a vertical direction, and the normal direction of the loading surface 1111 extends along the vertical direction. Of course, depending on the workpiece clamping and processing requirements, the first direction X can be deviated from the vertical direction or set to a horizontal direction. For ease of explanation, this embodiment uses the first direction X as the vertical direction for explanation. The pressure member 12 is disposed above the base 11 and can be raised and lowered.

[0066] The clamping device 100 also includes a drive assembly 13, which is used to drive the pressing component 12 to rise and fall. The drive assembly 13 can be configured as an electric drive module, a cylinder drive module or a hydraulic cylinder drive module, etc., for automatically driving the pressing component 12 to rise and fall; or, the rising and falling of the pressing component 12 can be controlled by manual drive, which is not limited here.

[0067] The positioning assembly 20 includes a stop 21 disposed on the base 11. A portion of the stop 21 protrudes from the loading surface 1111. When a workpiece needs to be clamped, at least a portion of the workpiece is placed on the loading surface 1111, and the edge of the workpiece is pressed against the stop 21 to achieve workpiece positioning. Subsequently, the clamping assembly 10's pressing member 12 clamps the workpiece. The overall clamping process is convenient and improves the ease of workpiece clamping. Optionally, the stop 21 can be configured as, but is not limited to, a long strip structure, a columnar structure, or a block structure.

[0068] Optionally, the stop 21 can be located outside the pressing area or within the pressing area of ​​the pressing member 12. When the stop 21 is set in the pressing area of ​​the pressing member 12, the protrusion height of the stop 21 can be set to be less than the thickness of the workpiece, or a clearance can be provided on the pressing member 12 to avoid the stop 21, or the stop 21 can be set to be liftable in the following embodiments, which is not limited here.

[0069] See also Figures 1 to 4 In one embodiment, the base 11 is provided with a mounting groove 1112 located on the material loading surface 1111. Part of the structure of the baffle 21 is provided in the mounting groove 1112 and can be movably arranged in the direction close to or away from the pressure member 12. The baffle 21 has a positioning state protruding from the material loading surface 1111 and a avoidance state retracted to below the material loading surface 1111.

[0070] In this embodiment, a mounting groove 1112 is provided on the base 11, and at least a portion of the structure of the stop member 21 is disposed in the mounting groove 1112. The stop member 21 can move up and down relative to the base 11 in a direction close to or away from the pressure member 12. This arrangement can adjust the height of the stop member 21 protruding from the loading surface 1111 according to the thickness of the workpiece, avoiding interference with the pressure member 12 or the processing head during subsequent processing due to excessive protrusion of the stop member 21. In addition, when there is no need to position the workpiece, such as during a straight-through continuous feeding process, the stop member 21 can be completely retracted below the loading surface 1111 to keep the stop member 21 in an avoidance state to avoid interference with the workpiece.

[0071] Optionally, a drive module can be set to drive the stop 21 to rise and fall, or the protrusion height of the stop 21 can be manually adjusted; or the stop 21 can be set in the pressing area of ​​the pressing member 12. When the pressing member 12 presses down close to the loading surface 1111, the stop 21 is pressed down. In the following embodiment, a first elastic member 22 can be set to drive the pressing member 12 to rise.

[0072] Please see Figure 5 In one embodiment, the positioning component 20 further includes a first elastic member 22, which acts between the base 11 and the stop member 21, and is used to drive the stop member 21 to protrude from the loading surface 1111.

[0073] In this embodiment, the positioning component 20 further includes a first elastic element 22 for driving the stop member 21 upward. The first elastic element 22 can be configured as a compression spring, positioned on the side of the stop member 21 opposite to the pressure member 12; or, the first elastic element 22 can be configured as a spring sheet, with one end connected to the base 11 and the other end connected to or positioned on the side of the stop member 21 opposite to the pressure member 12. In this configuration, the first elastic element 22 can apply an upward elastic force to the stop member 21, allowing the stop member 21 to automatically protrude from the material loading surface 1111 and maintain the required protrusion height.

[0074] Please see Figure 5 In one embodiment, the first elastic element 22 is configured as a spring sheet, one end of which is connected to the base 11; the other end of which is connected to the stop member 21, or is disposed on the side of the stop member 21 opposite to the pressure member 12.

[0075] In this embodiment, the first elastic element 22 is configured as a spring sheet, with one end connected to the base 11. For example, the base 11 has a back surface facing away from the loading surface 1111, and the mounting groove 1112 penetrates the loading surface 1111 and the back surface. The stop element 21 can protrude from the back surface in a direction away from the loading surface 1111, and one end of the spring sheet is fixed to this back surface; alternatively, the lower end of the stop element 21 is always located inside the mounting groove 1112, and the spring sheet can be fixed to the side wall or bottom wall of the mounting groove 1112. The other end of the spring sheet can be connected to the stop element 21, or the other end of the spring sheet can be located on the side of the stop element 21 facing away from the pressure element 12. The spring sheet is in a state of elastic bending deformation, thereby giving it a tendency to elastically recover towards the loading surface 1111, so as to apply an upward elastic force to the stop element 21.

[0076] Optionally, the positioning component 20 may include two or more springs. For example, the stop member 21 has two spaced ends, each end of which is provided with at least one spring; or, multiple springs are provided along the circumference of the stop member 21 so that the stop member 21 is subjected to balanced force.

[0077] See also Figure 4 and Figure 6 In one embodiment, the clamping device 100 further includes a locking and releasing structure 30, which is disposed on the base 11 and configured to lock the stop 21 when the stop 21 is in the avoidance state.

[0078] In this embodiment, the clamping device 100 further includes a locking and releasing structure 30 for locking the stop member 21 in an avoidance state. The locking and releasing structure 30 can be configured as a magnetic attraction structure, a snap-fit ​​structure, or a clamping structure, etc. With this configuration, when it is not necessary for the stop member 21 to protrude from the loading surface 1111, the stop member 21 retracts to below the loading surface 1111, and the locking and releasing structure 30 locks the stop member 21, preventing the stop member 21 from protruding from the loading surface 1111 and interfering with the workpiece or other devices.

[0079] See also Figure 4 and Figure 6 In one embodiment, the side wall of the material stop 21 is provided with a slot 211, and the locking and releasing structure 30 is provided with a snap-fit ​​member 31. The snap-fit ​​member 31 is movably disposed and has a locked position and an unlocked position. The direction of movement of the snap-fit ​​member 31 is perpendicular to the direction of movement of the material stop 12. When the material stop 21 is in the avoidance state, the snap-fit ​​member 31 engages with the slot 211 in the locked position.

[0080] In this embodiment, a slot 211 is provided on the side wall of the stop 21, and a latching member 31 that can engage with the slot 211 is provided in the locking and releasing structure 30. When the stop 21 retracts to the avoidance state, the latching member 31 is engaged in the slot 211 to lock the stop 21, preventing the stop 21 from protruding from the loading surface 1111. The locking strength is high and the locking state is relatively stable. The movement of the latching member 31 between the locked and unlocked positions can be manually controlled by the user; or automatically driven and controlled by an electric drive module, a cylinder drive module, or other structures; or, in the following embodiment, by providing an inclined surface 314 on the latching member 31 to engage with the stop 21, when the stop 21 retracts to the avoidance state, the stop 21 drives the latching member 31 to move from the locked position to the unlocked position; by providing a second elastic member 32, the latching angle moves from the unlocked position to the locked position.

[0081] See also Figure 4 and Figure 6 In one embodiment, the locking and releasing structure 30 further includes a second elastic member 32, which acts between the base 11 and the latching member 31 to drive the latching member 31 from the unlocked position to the locked position.

[0082] In this embodiment, the locking-releasing structure 30 further includes a second elastic member 32 for driving the latching member 31 from the unlocked position to the locked position. The second elastic member 32 can be configured as a compression spring, tension spring, magnetic spring, or sheet spring, and is not limited thereto. Before the stop member 21 retracts to the avoidance state and is locked by the locking-releasing structure 30, the locking-releasing structure 30 is in the unlocked position to avoid interfering with the stop member 21. At this time, the second elastic member 32 is in an elastically deformed state. Then, after the stop member 21 retracts to the avoidance state, the second elastic member 32 automatically drives the latching member 31 from the unlocked position to the locked position to engage with the stop member 21. There is no need to drive the latching member 31 to the locked position by manual, electric, or pneumatic control. The structure is simple and easy to use.

[0083] See also Figure 4 and Figure 5 In one embodiment, the base 11 is provided with a limiting structure 113. Along the movement direction of the snap-fit ​​member 31, the limiting structure 113 is located on one side of the snap-fit ​​member 31 and is provided with a limiting hole 1131. Part of the structure of the second elastic member 32 is provided in the limiting hole 1131.

[0084] In this embodiment, a limiting structure 113 is provided on the base 11. The limiting structure 113 is located on one side of the snap-fit ​​member 31 along its direction of movement and has a limiting hole 1131 with an opening facing the snap-fit ​​member 31. A portion of the structure of the second elastic member 32 is disposed in the limiting hole 1131 of the limiting structure 113. This arrangement can limit the second elastic member 32, reduce the risk of the second elastic member 32 falling off, and prevent the second elastic member 32 from deviating from its direction of movement.

[0085] See also Figure 4 and Figure 6 In one embodiment, the latching member 31 is provided with an inclined surface 314 on the side facing the material loading surface 1111. During the process of the material blocking member 21 moving to the avoidance state, it abuts against the inclined surface 314 and moves relative to the inclined surface 314 to drive the latching member 31 to move from the locked position to the unlocked position.

[0086] In this embodiment, the latching member 31 is provided with an inclined surface 314, which is inclined towards the material loading surface 1111 along the direction from the locked position to the unlocked position. During the process of the material stop 21 retracting to the avoidance state, the material stop 21 can abut against the inclined surface 314 and move relative to the inclined surface 314 during the continuous retraction, so as to drive the latching member 31 from the locked position to the unlocked position. With this configuration, the latching member 31 is moved to the unlocked position at the same time as the material stop 21 retracts to the avoidance state. This can avoid the latching member 31 interfering with the material stop 21, and there is no need to set up other driving structures 53 to drive the latching member 31 to the unlocked position before the material stop 21 retracts to the avoidance state. The structure is simple, the driving control steps are reduced, and the ease of use is improved.

[0087] See also Figure 1 and Figure 6 In one embodiment, the snap-fit ​​member 31 includes a snap-fit ​​portion 311, a connecting portion 312, and a pressing portion 313. Along the movement direction of the snap-fit ​​member 31, the two ends of the connecting portion 312 are respectively connected to the snap-fit ​​portion 311 and the pressing portion 313. The snap-fit ​​portion 311 is used to snap-fit ​​with the stop member 21. The pressing portion 313 is provided to protrude from the side of the base 11 at least when the snap-fit ​​member 31 is in the locked position.

[0088] In this embodiment, the latching member 31 includes a latching portion 311, a connecting portion 312, and a pressing portion 313 arranged along the movement direction (i.e., the second direction Y) of the latching member 31. One end of the connecting portion 312 is connected to the latching portion 311, and the other end of the connecting portion 312 is connected to the pressing portion 313. Optionally, the connecting portion 312 can be disposed on the side of the stop member 21 facing away from the pressing member 12, or it can be disposed on the side of the stop member 21. The latching portion 311 is configured to engage with the latching groove 211 of the stop member 21, and the pressing portion 313 protrudes from the side of the base 11 at least when the latching member 31 is in the locked position. With this configuration, when it is necessary to release the latching member 31 from the locking position to the stop member 21, the latching member 31 can be moved from the locked position to the unlocked position by pressing the pressing portion 313. When it is necessary for the latching member 31 to move to the unlocked position to avoid interfering with the process of the stop member 21 moving to the avoidance state, the latching member 31 is also moved from the locked position to the unlocked position by pressing the pressing part 313. Of course, in some embodiments, when it is necessary for the latching member 31 to move to the unlocked position to avoid interfering with the process of the stop member 21 moving to the avoidance state, this can be achieved by providing an inclined surface 314 on the latching member 31 to cooperate with the stop member 21 in the above embodiment, thereby improving ease of use.

[0089] Optionally, in some embodiments, the base 11 includes a material carrier plate 111 and a first enclosure plate 112. The material carrier plate 111 is provided with a bearing surface and a mounting groove 1112. The mounting groove 1112 is disposed through the material carrier plate 111. Along the movement direction of the snap-fit ​​member 31, the first enclosure plate 112 is located on one side of the material carrier plate 111. The pressing part 313 can be inserted through the first enclosure plate 112 to protrude outward.

[0090] Optionally, in some embodiments, an installation space 45 for mounting the snap-fit ​​31 can be provided in the base 11 to limit the snap-fit ​​31; or, the snap-fit ​​31 can be mounted on the base 11 using locking accessories such as bolts. For example, a slot extending along the movement direction of the snap-fit ​​31 can be provided on the connecting part 312, the bolt can pass through the slot, one end of the bolt can be connected to the base 11, and the bolt head can be located on the side of the connecting part 312 opposite to the material loading surface 1111, so as to prevent the snap-fit ​​31 from falling off.

[0091] Please see Figure 1 In one embodiment, the clamping device 100 further includes two guide rails 40 arranged side by side, and the two ends of the base 11 are slidably connected to the two guide rails 40 respectively.

[0092] In this embodiment, two guide rails 40 are arranged side by side in the clamping device 100. The arrangement direction of the two guide rails 40 (i.e., the third direction Z in the figure) is perpendicular to the extension direction of the guide rails 40 (i.e., the second direction Y in the figure). This allows the two ends of the base 11 of the clamping assembly 10 to be slidably connected to the two guide rails 40 respectively. A slider can be connected to the end of the base 11 to cooperate with the guide rail 40 to form a guide rail 40 slider mechanism. In this case, the guide rail 40 can be configured as a ball bearing guide rail 40, dovetail guide rail 40, or similar structures. Alternatively, a first rolling element 14 can be provided at the end of the base 11 to roll and cooperate with the guide rail 40. This arrangement allows the clamping assembly 10 to slide along the extension direction of the guide rail 40 (i.e., the second direction Y in the figure) to adjust its position. The two guide rails 40 together guide and limit the sliding process of the clamping assembly 10 from both ends, preventing the clamping assembly 10 from deviating from the sliding direction and improving the stability of the clamping assembly 10 during the sliding process.

[0093] See also Figure 7 and Figure 11 In one embodiment, the clamping assembly 10 further includes a first rolling element 14 connected to the end of the base 11; the first rolling element 14 is supported on the guide rail 40 and can roll relative to the guide rail 40 to allow the clamping assembly 10 to slide along the guide rail 40.

[0094] In this embodiment, a rotatably mounted first rolling element 14 is connected to the end of the base 11. The first rolling element 14 can be directly connected to the base 11, or a connecting structure 15 can be provided at the end of the base 11 for mounting the first rolling element 14. The first rolling element 14 is supported on the guide rail 40 and can roll along the guide rail 40 to allow the clamping assembly 10 to slide along the guide rail 40. This arrangement results in rolling friction between the clamping assembly 10 and the guide rail 40, which helps reduce the frictional force between them, allowing the clamping assembly 10 to slide more smoothly and stably. Optionally, the first rolling element 14 can be configured as a roller, ball, or other structure. Optionally, a rolling groove 431 can be provided on the guide rail 40, allowing the first rolling element 14 to be positioned and guided within the rolling groove 431, preventing it from deviating from the direction of movement.

[0095] See also Figure 7 and Figure 13In one embodiment, the guide rail 40 includes a top plate 41, a first side plate 42, and a support base 43. The first side plate 42 is connected to one side of the top plate 41. The support base 43 is connected to the side of the first side plate 42 away from the top plate 41 and is disposed opposite to the top plate 41. The support base 43, the first side plate 42, and the top plate 41 enclose an installation space 45. The first rolling element 14 is located in the installation space 45 and is supported by the support base 43.

[0096] In this embodiment, the guide rail 40 includes a top plate 41, a first side plate 42, and a support base 43. The top plate 41 and the support base 43 are arranged opposite each other in the vertical direction (i.e., the first direction X), and the top plate 41 is located above the support base 43. The first side plate 42 is used to connect the top plate 41 and the support base 43. The top plate 41, the first side plate 42, and the support base 43 enclose and form an installation space 45 for accommodating the first rolling element 14. The installation space 45 can be located on the side of the first side plate 42 facing the other guide rail 40, or it can be located on the side of the first side plate 42 facing away from the guide rail 40. By placing the first rolling element 14 in the installation space 45 and supporting it on the support base 43, the stability of the mating structure between the first rolling element 14 and the guide rail 40 is improved. Furthermore, by covering most of the surface of the first rolling element 14 with the guide rail 40, a dustproof function can be effectively achieved, preventing foreign objects from adhering between the first rolling element 14 and the support base 43.

[0097] See also Figure 7 , Figure 11 as well as Figure 13 In one embodiment, the guide rail 40 has a top surface 411 and a brake surface 412 facing each other, and the base 11 spans over the top surface 411; the clamping assembly 10 also includes a connecting structure 15 and a brake element 16, the connecting structure 15 is connected to the end of the base 11 and extends from the base 11 toward the brake surface 412; the brake element 16 is connected to the connecting structure 15 and is disposed opposite to the brake surface 412; the clamping device 100 also includes a lifting mechanism 50, the lifting mechanism 50 is connected to the base 11 and is used to drive the base 11 to move the connecting structure 15 and the brake element 16 toward or away from the brake surface 412.

[0098] In this embodiment, the guide rail 40 is provided with an upward-facing top surface 411 and a downward-facing brake surface 412, and the mounting space 45 is located below the brake surface 412. The clamping assembly 10 includes a connecting structure 15 connected to the end of the base 11, part of which is lower than the brake surface 412. The clamping assembly 10 also includes a brake element 16 connected to the connecting structure 15. The brake element 16 is located in the mounting space 45 and is positioned opposite to the brake surface 412. When the position of the clamping assembly 10 needs to be adjusted, the brake element 16 is spaced apart from the brake surface 412. When the position of the clamping assembly does not need to be adjusted, the lifting mechanism 50 raises the base 11, causing the clamping assembly 10 to float upwards. At this time, the first rolling element 14 is spaced apart from the support base 43, and the brake element 16 abuts against the brake surface 412. The static friction between the brake element 16 and the brake surface 412 locks the clamping assembly onto the guide rail 40, preventing the clamping assembly 10 from continuing to slide and ensuring that the clamping assembly 10 is in a stable clamping position. Optionally, the brake component 16 may be made of a material with a high coefficient of surface friction, such as rubber, asbestos or other materials, and a rough texture may be provided on the surface of the brake component 16 to improve friction.

[0099] Optionally, the lifting mechanism 50 can be configured as a cylinder or hydraulic cylinder lifting mechanism, or a motor lead screw 132 mechanism, etc. Of course, it can also be configured as a combination of the mounting base 51 and the pressing structure 52 in the following embodiment, which is not limited here.

[0100] Optionally, the clamping assembly 10 is provided with a first rolling element 14, which is rotatably connected to a portion of the connecting structure 15 located below the brake surface 412, so that the first rolling element 14 can be located in the mounting space 45 below the brake surface 412. When the first rolling element 14 is supported on the support base 43, the first rolling element 14 is spaced apart from the brake surface 412.

[0101] Please see Figure 8 In one embodiment, the base 11 has a through hole opposite to the top surface 411; the lifting mechanism 50 includes a mounting base 51, a pressing structure 52, and a driving structure 53. The mounting base 51 is disposed on the surface of the base 11 opposite to the top surface 411. The pressing structure 52 is vertically mounted on the mounting base 51 and passes through the through hole, abutting against the top surface 411. The driving structure 53 is disposed on the mounting base 51 and drives the pressing structure 52 to move relative to the mounting base 51, so that the mounting base 51 drives the base 11 to move in a direction closer to or away from the top surface 411.

[0102] In this embodiment, the lifting mechanism 50 includes a mounting base 51 connected to the base 11, and a pressing structure 52 and a driving structure 53 disposed on the mounting base 51. The mounting base 51 is fixed to the side of the base 11 facing away from the top surface 411 of the guide rail 40, while the pressing structure 52 passes through a through hole in the base 11, with one end of the pressing structure 52 abutting against the top surface 411 of the guide rail 40. It is understood that in practical applications, the guide rail 40 is fixed to the frame of the processing equipment, and its position remains fixed, thereby keeping the position of the pressing structure 52 relatively fixed. When the driving structure 53 drives the pressing structure 52 and the mounting base 51 to move relative to each other, it drives the mounting base 51 relative to the pressing structure 52. The guide rail 40 moves up and down, thereby driving the base 11 to move up and down, so that the connecting structure 15, the brake component 16, and the first rolling component 14 and other structures move up and down together; when the drive structure 53 drives the mounting seat 51 to drive the base 11 and the brake component 16 and other structures to rise, the brake component 16 abuts against the brake surface 412 to lock the clamping assembly 10; when the drive structure 53 drives the mounting seat 51 to drive the base 11 and the brake component 16 and other structures to fall, the brake component 16 moves away from the brake surface 412 to release the lock on the clamping assembly 10.

[0103] Optionally, the drive structure 53 can be equipped with a cam structure 531 rotatably connected to the mounting base 51. The cam surface of the cam structure 531 abuts against the pressing structure 52. When the cam structure 531 rotates, the distance between the axis of rotation of the cam structure 531 and the pressing structure 52 changes, thus generating relative motion between the mounting base 51 and the pressing structure 52. Alternatively, the drive structure 53 can also be configured as a cylinder drive structure 53. The cylinder body is connected to the mounting base 51, and the piston rod of the cylinder is connected to or abuts against the pressing structure 52. When the piston rod extends or retracts, it can generate relative motion between the mounting base 51 and the pressing structure 52. Of course, the drive structure 53 can also be configured with other structural types, which are not limited here.

[0104] Please see Figure 9 and Figure 10 In one embodiment, the drive structure 53 is rotatably connected to the mounting base 51 and is provided with a cam structure 531, which abuts against the pressing structure 52.

[0105] In this embodiment, the drive structure 53 includes at least a cam structure 531. Optionally, the drive structure 53 may also include a handle 532 connected to the cam structure 531, extending the rotation arm via the handle 532 to drive the cam structure 531 to rotate. The pressing structure 52 is provided with a drive part for abutting against the cam structure 531. The end of the pressing structure 52 away from the guide rail 40 can be used as the drive part, or the pressing structure 52 can include a main structure 521 and a drive part protruding from the side of the main structure 521. The cam structure 531 abuts against the side of the drive part opposite to the guide rail 40. Under the gravity of the base 11, the mounting base 51, and the cam structure 531, the cam structure 531 always maintains contact with the drive part of the pressing structure 52. When the cam structure 531 rotates, the distance between the axis of rotation of the cam structure 531 and the pressing structure 52 changes, which causes relative movement between the mounting base 51 and the pressing structure 52, thereby driving the base 11 to rise and fall. The structure is simple and easy to operate.

[0106] In some embodiments, the clamping device 100 includes two sets of lifting mechanisms 50, which are respectively disposed at both ends of the clamping assembly 10, so that both ends of the clamping assembly 10 can be lifted to lock with the two guide rails 40 respectively. Optionally, a connecting rod 54 can be provided to connect the drive structures 53 of the two sets of lifting mechanisms 50, for example, the connecting rod 54 can be connected to the handles 532 of the two drive structures 53, so that the two drive structures 53 can operate synchronously.

[0107] Please see Figure 9 and Figure 10 In one embodiment, the mounting base 51 is provided with a guide hole 511 opposite to the through hole, and the side wall of the mounting base 51 is provided with a guide groove 512 communicating with the guide hole 511. The pressing structure 52 includes a main structure 521 and a pushing structure 522. The main structure 521 passes through the guide hole 511 and the through hole, and the pushing structure 522 passes through the guide groove 512. Part of the pushing structure 522 is located in the guide hole 511 and abuts against the main structure 521, and another part of the pushing structure 522 is located outside the mounting base 51 and abuts against the cam structure 531.

[0108] In this embodiment, the pressing structure 52 includes a main body structure 521 for abutting against the guide rail 40 and a pushing structure 522 for cooperating with the driving structure 53. The main body structure 521 passes through the through hole and abuts against the guide rail 40, and a portion of the main body is disposed in the guide hole 511 of the mounting base 51, so that the pressing structure 52 is stably connected to the mounting base 51, which can prevent the pressing structure 52 from deviating from the direction of movement during the relative movement of the mounting base 51. The pushing structure 522 includes a driving part protruding from the side of the main body structure 521. The driving part passes through the guide groove 512 of the mounting base 51 so that the driving part is located outside the mounting base 51. The cam structure 531 of the driving structure 53 is located outside the mounting base 51 and abuts against the driving part.

[0109] Optionally, the portion of the push structure 522 located in the guide hole 511 abuts against the main structure 521. The push structure 522 can abut against the end of the main structure 521, or the push structure 522 can be connected to the side of the main structure 521.

[0110] Please see Figure 10 In one embodiment, the push structure 522 includes a first push member 5221 and a second push member 5224. The first push member 5221 is provided with a push portion 5223 that abuts against the end of the main structure 521. The second push member 5224 is connected to the first push member 5221. The second push member 5224 passes through the guide hole 511 and abuts against the cam structure 531. Along the length direction of the push structure 522, the connection position of the second push member 5224 with the first push member 5221 is adjustable.

[0111] In this embodiment, the pushing structure 522 includes a first pushing member 5221 and a second pushing member 5224 connected together. The first pushing member 5221 includes a connected insertion portion 5222 and a pushing portion 5223, with the pushing portion 5223 abutting against the end of the main body structure 521 facing away from the guide rail 40. The second pushing member 5224 is angled to and connected to the insertion portion 5222 of the first pushing member 5221. A portion of the structure of the second pushing member 5224 extends outward through the clearance groove 5216 of the main body guide rail 40 and the guide groove 512 of the mounting base 51 to serve as a driving part that abuts against the cam structure 531. In this configuration, the cam structure 531 applies a pushing force to the second pushing member 5224, causing the second pushing member 5224 to drive the first pushing member 5221 to generate a pressing force on one side of the guide rail 40, thus pressing the first pushing member 5221 against the main body structure 521.

[0112] Optionally, a screw hole can be provided in the second pusher 5224, and the insertion part 5222 of the first pusher 5221 can be configured as a screw and threadedly connected to the screw hole; alternatively, a mounting hole can be provided in the insertion part 5222 of the first pusher 5221, so that the second pusher 5224 can be inserted into the mounting hole; of course, the first pusher 5221 and the second pusher 5224 can also adopt a snap-fit ​​or other connection method, which is not limited here.

[0113] Please see Figure 10 In one embodiment, the main structure 521 is provided with a insertion hole 5215, and the side wall of the main structure 521 is provided with a clearance groove 5216 communicating with the insertion hole 5215; the insertion part 5222 of the first pusher 5221 is inserted into the insertion hole 5215, and the pusher part 5223 is located outside the insertion hole 5215 and abuts against the end of the main structure 521; the second pusher 5224 passes through the clearance groove 5216 and is connected to the insertion part 5222. In this arrangement, the insertion part 5222 is inserted into the insertion hole 5215, while the second pusher 5224 passes through the clearance groove 5216 on the side wall of the main structure 521, which helps to improve the connection stability between the pusher structure 522 and the main structure 521, and the pusher structure 522 and the main structure 521 are not easily separated.

[0114] In one embodiment, the second pusher 5224 is adjustable in the connection position of the insertion portion 5222 along the length direction of the pusher structure 522.

[0115] In this embodiment, by changing the connection position of the second pusher 5224 on the insertion part 5222, the distance between the second pusher 5224 and the pusher part 5223 can be adjusted, thereby adjusting the pushing force applied by the cam structure 531 to the main structure 521 through the pusher structure 522, thereby adjusting the pressure of the pressing structure 52 on the guide rail 40, as well as the squeezing force and friction between the brake member 16 and the brake surface 412 when locking the clamping assembly 10.

[0116] Optionally, the first pusher 5221 and the insertion part 5222 can be threaded together, allowing the first pusher 5221 to move along the length of the insertion part 5222 by rotating relative to the insertion part 5222, thereby adjusting the connection position. For example, the second pusher 5224 can be a bolt, with the bolt head serving as the pusher part 5223 that abuts against the end of the main structure 521, and the screw serving as the insertion part 5222 inserted into the guide hole 511 and threadedly connected to the first pusher 5221. Alternatively, the first pusher 5221 and the insertion part 5222 can be locked together by a set screw, or multiple mounting holes can be provided in the insertion part 5222, with the first pusher 5221 passing through different mounting holes to adjust the connection position.

[0117] Please see Figure 10 In one embodiment, the main structure 521 includes a connector 5211, a third elastic member 5212, and a pressure head 5213. The connector 5211 is vertically and vertically inserted through the guide hole 511 and the through hole. The side wall of the connector 5211 is provided with a limiting step 5214 facing the guide rail 40. The pressure head 5213 is located at one end of the connector 5211 facing the guide rail 40 and abuts against the top surface 411. The third elastic member 5212 is located between the limiting step 5214 and the pressure head 5213.

[0118] In this embodiment, the main structure 521 includes a connector 5211, a third elastic member 5212, and a pressure head 5213. The connector 5211 is vertically and vertically inserted through the guide hole 511 and the through hole. The pressure head 5213 abuts against the guide rail 40. The third elastic member 5212 is positioned between the pressure head 5213 and the limiting step 5214 of the connector 5211 and is in a compressed state. The third elastic member 5212 can apply a preload to the pressure head 5213 and an upward elastic force to the connector 5211 to ensure that the connector 5211 and the pushing structure 522 maintain a stable abutment relationship.

[0119] In one embodiment, the end of the pressing structure 52 that abuts against the top plate 41 is provided with a pressing head 5213, which is made of an elastic material.

[0120] This configuration avoids rigid contact between the pressure structure 52 and the guide rail 40. When the pressure head 5213 and the guide rail 40 come into contact, the pressure head 5213 can undergo elastic deformation, thus preventing damage to the guide rail 40.

[0121] See also Figure 7 and Figure 11 In one embodiment, the connecting structure 15 includes a first block 151 and a second block 152 connected to each other. The first block 151 is connected to the base 11 and is located on the side of the guide rail 40 opposite to the other guide rail 40. The second block 152 is disposed opposite to the brake surface 412, and the brake member 16 and the first rolling member 14 are respectively connected to the second block 152.

[0122] In this embodiment, the guide rail 40 forms an installation space 45 by enclosing the top plate 41, the first side plate 42, and the support base 43. A connecting structure 15 is provided in the clamping assembly 10 and connected to the end of the base 11. The connecting structure 15 includes a first block 151 and a second block 152. The base 11 spans above the top surface 411 of the guide rail 40, such that the first block 151 is located on the side of the guide rail 40 facing away from the other guide rail 40. The second block 152 can be directly connected to the surface of the first block 151 facing the installation space 45, or it can be connected to the first block 151 via a third block 153 as described in the following embodiment. The first rolling element 14 and the brake element 16 are both connected to the second block 152. This configuration is equivalent to the clamping assembly 10 covering the outside of the guide rail 40, which helps to improve the connection stability between the clamping assembly 10 and the guide rail 40, making the sliding process of the clamping assembly 10 relative to the guide rail 40 more stable. In addition, the connecting structure 15 can also shield the installation space 45 inside the guide rail 40, improving dust prevention.

[0123] Optionally, the connection method between the brake component 16 and the second block 152 can be, but is not limited to, bonding or snap-fitting. In one embodiment, the second block 152 is provided with a snap-fit ​​groove, and the end of the brake component 16 is snapped into the snap-fit ​​groove, making it easy to assemble and disassemble.

[0124] See also Figure 7 and Figure 11 In one embodiment, the connecting structure 15 further includes a third block 153, with the first block 151 and the second block 152 spaced apart and respectively connected to the two ends of the third block 153; the guide rail 40 further includes a second side plate 44, which is connected to the side of the top plate 41 near the first block 151 and is located between the first block 151 and the second block 152.

[0125] In this embodiment, the connecting structure 15 includes a first block 151, a second block 152, and a third block 153. The third block 153 is connected to the first block 151 and the second block 152 respectively, and is located at the end of the first block 151 and the second block 152 away from the brake surface 412, so that the first block 151 and the second block 152 are spaced apart along the arrangement direction of the two guide rails 40 (i.e., the third direction Z in the figure). The guide rail 40 also includes a second side plate 44 disposed opposite to the first side plate 42. The second side plate 44 is connected to the top plate 41 and spaced apart from the support base 43 to form a clearance opening communicating with the installation space 45 between the second side plate 44 and the support base 43. The second block 152 can pass through the clearance opening so that the first rolling element 14 and the brake element 16 are disposed in the installation space 45, and the second side plate 44 is located between the first block 151 and the second block 152. The second side plate 44 can improve the dustproof capability of the installation space 45, and also help to improve the connection strength and stability between the clamping assembly 10 and the guide rail 40.

[0126] See also Figure 7 and Figure 11 In one embodiment, the clamping assembly 10 further includes a second rolling element 17, which is rotatably connected to the second block 152, and the rolling surface of the second rolling element 17 abuts against the side wall of the mounting space 45.

[0127] In this embodiment, the clamping assembly 10 further includes a second rolling element 17 rotatably connected to the second block 152. The axis of rotation of the second rolling element 17 extends along the first direction X. The second rolling element 17 is located in the mounting space 45 and abuts against the side wall of the mounting space 45. For example, the second rolling element 17 can abut against the first side plate 42. Alternatively, in some embodiments, the guide rail 40 is provided with a second side plate 44, and the second rolling element 17 can also abut against the second side plate 44. With this configuration, when the clamping assembly 10 slides relative to the guide rail 40, the second rolling element 17 can also roll along the guide rail 40, which is beneficial for limiting the clamping assembly 10 in the third direction Z and improving the stability of the clamping assembly 10 sliding relative to the guide rail 40, thus preventing the clamping assembly 10 from deviating from the direction of movement during sliding due to uneven force on the clamping assembly 10.

[0128] Please see Figure 8 In one embodiment, the drive assembly 13 includes a nut 131 and a lead screw 132. The nut 131 is connected to the pressure member 12, and the lead screw 132 passes through the nut 131 and engages with the nut 131. One end of the lead screw 132 passes through the nut 131 and engages with the nut 131, and the other end of the lead screw 132 is connected to the base. Along the movement direction of the pressure member 12, the lead screw remains fixed relative to the base.

[0129] In this embodiment, the drive assembly 13 in the clamping assembly 10 for driving the pressing member 12 to rise and fall includes a nut 131 and a lead screw 132. The nut 131 is connected to the pressing member 12, and the lead screw 132 extends along the direction of movement of the pressing member 12 (i.e., the first direction X in the figure) and is rotatably inserted through the nut 131 to engage with it. The lead screw 132 remains fixed relative to the base 11 in the first direction X. By driving the lead screw 132 to rotate, the nut 131 can be moved along the direction of movement of the pressing member 12, causing the pressing member 12 to move closer to or away from the loading surface 1111 of the base 11.

[0130] Optionally, in the following embodiments, a rotating mechanism can be connected to the lead screw 132 to manually drive the lead screw 132 to rotate. Alternatively, a drive motor or rotary cylinder can be directly connected to the lead screw 132, or the drive motor and rotary cylinder can be connected to the lead screw 132 via a transmission structure such as gear drive, belt drive, linkage drive, or chain drive to achieve automatic rotation of the lead screw 132. No limitation is imposed here.

[0131] Optionally, the pressure member 12 is provided with a connecting hole for installing the nut 131, so that the nut 131 can be interference-fitted into the connecting hole, or fixed into the mounting hole by means of bonding or other methods; in some embodiments, the hole wall of the connecting hole is provided with a first limiting groove, and the outer wall of the nut 131 is provided with a second limiting groove corresponding to the first limiting groove, and a positioning pin 135 is provided to be engaged in the first limiting groove and the second limiting groove to ensure that the nut 131 will not rotate in the connecting hole.

[0132] Alternatively, a snap ring 136, a shoulder screw, or other structure can be used to keep the nut 131 and the pressure member 12 in a relatively fixed position in the direction of movement of the pressure member 12, so as to prevent the nut 131 from moving relative to the pressure member 12 in the direction of movement of the pressure member 12, which would prevent the pressure member 12 from pressing the workpiece well.

[0133] See also Figure 5 and Figure 8 In one embodiment, the drive assembly 13 includes two sets of nuts 131 and lead screws 132 respectively disposed at both ends of the pressure member 12. The drive assembly 13 also includes a transmission mechanism 133 connecting the two lead screws 132. The transmission mechanism 133 is used to make the two lead screws 132 rotate synchronously.

[0134] In this embodiment, the drive assembly 13 includes a mating structure of two sets of lead screws 132 and nuts 131. One set of lead screws 132 and nuts 131 is located at one end of the pressure member 12, and the other set is located at the other end of the pressure member 12. The arrangement of two sets of lead screws 132 and nuts 131 improves the stability of the pressure member 12's movement. Simultaneously, the two lead screws 132 are connected by a transmission mechanism 133, ensuring that the two lead screws 132 rotate synchronously, guaranteeing that both ends of the pressure member 12 rise and fall synchronously and maintain a consistent moving distance, thus preventing the pressure member 12 from tilting. This arrangement also reduces the need for drive mechanisms to rotate the lead screws 132; by driving one lead screw 132 to rotate, the other lead screw 132 can be driven to rotate synchronously, simplifying the overall structure of the clamping assembly 10 and improving driving convenience.

[0135] Optionally, the transmission mechanism 133 can be configured as a synchronous belt transmission mechanism 133, a chain transmission mechanism 133, or a gear transmission mechanism 133, etc., and is not limited thereto. In one embodiment, pulleys 1331 are sleeved on both lead screws 132, and the synchronous belt 1332 is wound around the two pulleys 1331. When one lead screw 132 rotates, it drives the other lead screw 132 to rotate through the synchronous belt transmission mechanism 133. Optionally, a fixed seat 134 can be provided on the base 11, and the pulleys 1331 can be rotatably mounted on the fixed seat 134.

[0136] Please see Figure 8 In one embodiment, the drive assembly 13 further includes a rotating wheel 137 connected to one end of the lead screw 132.

[0137] In this embodiment, the lead screw 132 can be manually driven to rotate. Rotating the rotating wheel 137 drives the lead screw 132 to rotate, which in turn drives the nut 131 to raise and lower the pressure member 12. The rotating wheel 137 also increases the rotation arm, making it easier to drive the lead screw 132 to rotate. This manual drive eliminates the need for motors or cylinders, simplifying the structure. Of course, in some embodiments, a motor or cylinder can be included alongside the rotating wheel 137 to achieve greater control versatility and flexibility, meeting different usage requirements.

In this case, the processing head is set as a laser output head. Optionally, the laser processing equipment can also be equipped with structures such as cutting tools, so that the laser processing equipment can also use cutting tools to perform processing, in order to meet different processing needs and improve compatibility.
