[0039] The utility model provides a kind of clamping mechanism 320, it is applied to processing equipment, for clamping installation processing head.It can be understood that the above processing equipment is not limited to a certain specific type of processing equipment, such as can be laser processing equipment, machine tool or machining center etc..The type of processing head clamped by clamping mechanism 320 is also not limited to a certain specific type, such as can be needle knife, turning tool, hob, cutting knife, brush or other types of processing head etc..The specific structure of clamping mechanism 320 is described below.

[0040] In the embodiments of the utility model, as shown in Figures 1 to 4 The clamping mechanism 320 includes a bracket 321, a clamp 322, a buckle 323 and a trigger 324.

[0041] The bracket 321 is provided with an opening slot 3211 for mounting the processing head; the clamp 322 is hinged with the bracket 321, for closing or opening the opening slot 3211; the buckle 323 is arranged on the bracket 321, for buckling with the free end of the clamp 322 when the clamp 322 closes the opening slot 3211, to clamp and fix the processing head located in the opening slot 3211; the trigger 324 is rotationally connected with the bracket 321 and transmissionally connected with the buckle 323; the trigger 324 can drive the buckle 323 to move relative to the bracket 321, to clamp or disengage the clamp 322.

[0042] In the embodiment, the bracket 321 plays a role of mounting and supporting various components (such as a clamp, a machining head, etc.), and when applied to a machining device, the bracket 321 can be mounted on a tool pressure control mechanism, or a feeding driving mechanism, or a rack of the machining device, etc. One side of the bracket 321 is provided with an open slot 3211, and the machining head is mounted at the open slot 3211, and the clamp 322 is used to close or open the open slot 3211 to realize the clamping or releasing function of the machining head.

[0043] Specifically, one end of the clamp 322 is hinged to the bracket 321, and the free end thereof can move close to or away from the bracket 321 to close or open the open slot 3211, and when the clamp 322 moves to close the open slot 3211, the free end of the clamp 322 is clamped by the buckle 323, so that the clamping and mounting function of the machining head is realized. When it is necessary to dismount or replace the machining head, the buckle 323 is driven to move relative to the bracket 321 by the trigger 324 to be separated from the free end of the clamp 322, so as to release the restriction on the clamp 322, and then release the clamping restriction on the machining head, so that the function of dismounting the machining head is realized.

[0044] It can be understood that in actual application, the specific structure of the buckle 323 can be determined according to actual conditions, such as a block shape, a strip shape, a rod shape or other special shapes, as long as the buckle 323 can be buckled with the clamp 322. In actual application, the specific structure of the trigger 324 can also be determined according to actual conditions, as long as the trigger 324 can drive the buckle 323 to move relative to the bracket 321 when triggered, for example, a wrench structure, a knob structure, a buckle structure or a key structure, etc. which are convenient for the operator to operate, so as to improve the dismounting convenience of the machining head.

[0045] In summary, in the clamping mechanism of the technical scheme, the bracket 321 is provided with the open slot 3211, the clamp 322, the buckle 323 and the trigger 324 are arranged on the bracket 321, the clamp 322 is hinged to the bracket 321, so that the clamp 322 can rotate relative to the bracket 321 to close or open the open slot 3211. When the clamp 322 rotates to close the open slot 3211, the buckle 323 can be buckled with the clamp 322 to clamp the clamp 322, so that the clamp 322 can clamp the machining head in the open slot 3211 to realize the mounting of the machining head. When it is necessary to dismount the machining head, the operator can trigger the trigger 324 to drive the buckle 323 to be separated from the clamp 322, so as to release the clamping force on the machining head and realize the dismounting of the machining head. In this way, compared with the existing screwing mode for mounting the machining head, the mounting operation is simplified, and the mounting convenience of the machining head is improved.

[0046] In an embodiment of the present application, as shown in Figures 1 to 4 the buckle 323 is rotationally connected with the bracket 321.

[0047] With this configuration, when the trigger 324 is triggered, the fastener 323 can be driven to rotate relative to the bracket 321 so as to engage or disengage with the clamp 322.

[0048] Optionally, the fastener 323 is rotatably connected to the bracket 321 via the first connecting pin 3251. When the trigger 324 is triggered, it drives the fastener 323 to rotate around the first connecting pin 3251.

[0049] Specifically, the fastening member 323 includes a fastening part 3232 and a first transmission part 3231 respectively disposed at both ends of its rotation center. The fastening part 3232 is located on one side of the opening groove 3211 for engaging with the clamp 322. The first transmission part 3231 is connected to the trigger member 324 for driving the fastening part 3232 to move closer to or away from the clamp 322.

[0050] Understandably, the fastener 323 is rotatably connected to the bracket 321 via the first connecting pin 3251. The fastening part 3232 and the first transmission part 3231 are respectively located on both sides of the first connecting pin 3251. The trigger 324 is connected to the first transmission part 3231 and can drive the fastener 323 to rotate around the first connecting pin 3251 by driving the first transmission part 3231 to move, thereby driving the fastening part 3232 to move closer to or away from the opening slot 3211 so as to engage or disengage from the clamp 322.

[0051] Optionally, the fastener 323 has a plate-like structure, with one end being the fastening part 3232 and the other end being the first transmission part 3231, and the first connecting pin 3251 is located approximately in the middle of the fastener 323.

[0052] Furthermore, such as Figures 1 to 3 The fastening part 3232 has a slot 32321 on the side facing the opening slot 3211, and the free end of the clamp 322 has a protrusion 3221 for holding and engaging in the slot 32321.

[0053] With this configuration, when the machining head needs to be installed, it is first placed in the opening slot 3211, and then the clamp 322 is rotated to close the opening slot 3211. At the same time, the locking protrusion 3221 at the free end of the clamp 322 engages in the locking groove 32321 of the fastening part 3232, thereby limiting the clamp 322 to clamp the machining head. When the machining head needs to be removed, the trigger 324 drives the fastening part 323 to rotate through the first transmission part 3231, causing the fastening part 3232 to move away from the clamp 322, thereby disengaging the locking groove 32321 from the locking protrusion 3221, thus unlocking the clamp 322 to release the machining head.

[0054] To further improve the installation convenience, in an embodiment, the trigger member 324 is a wrench, so that the worker can directly achieve the locking and releasing functions of the tool by turning the wrench. Alternatively, the trigger member 324 is hinged to the support 321 through a second connecting pin 3252, and the worker turns the wrench around the second connecting pin 3252 to drive the clamping member 323 to move. Figures 2 to 5 The slot wall of the clamping slot 32321 is provided with an abutting surface 3232a; when the clamping hoop 322 moves towards the open slot 3211, the clamping protrusion 3221 can extend into the clamping slot 32321 and abut against the abutting surface 3232a to drive the clamping member 3232 to move towards the open slot 3211.

[0055] In this way, when the clamping hoop 322 is turned to close the open slot 3211, the clamping protrusion 3221 of the clamping hoop 322 abuts against the abutting surface 3232a and drives the clamping member 3232 to move towards the open slot 3211, so that the clamping protrusion 3221 is completely clamped into the clamping slot 32321 and is clamped and matched with the clamping slot 32321, thereby achieving the clamping and matching of the clamping member 323 and the clamping hoop 322.

[0056] In this embodiment, the clamping hoop 322 can be directly turned to the position where the clamping member 323 is clamped to close the open slot 3211, without the need for additional driving of other components to move, thereby further simplifying the operation and improving the installation convenience.

[0057] In an embodiment of the present application, the trigger member 324 is a wrench, so that the worker can directly achieve the locking and releasing functions of the tool by turning the wrench. Alternatively, the trigger member 324 is hinged to the support 321 through a second connecting pin 3252, and the worker turns the wrench around the second connecting pin 3252 to drive the clamping member 323 to move. Figures 1 to 4 The trigger member 324 is a wrench, so that the worker can directly achieve the locking and releasing functions of the tool by turning the wrench. Alternatively, the trigger member 324 is hinged to the support 321 through a second connecting pin 3252, and the worker turns the wrench around the second connecting pin 3252 to drive the clamping member 323 to move.

[0058] Specifically, the wrench has a hand-held portion 3242 and a second transmission portion 3241 which are separately arranged on both sides of the rotation center of the wrench, and the second transmission portion 3241 is connected with the first transmission portion 3231 through a third connecting pin 3253. It can be understood that the third connecting pin 3253 is located at one end of the wrench away from the hand-held portion 3242, and the second connecting pin 3252 is closer to the third connecting pin 3253 relative to the end of the hand-held portion 3242, so that the force arm on the side of the hand-held portion 3242 is increased, thereby achieving the function of further saving labor.

[0059] In actual application, the worker can turn the hand-held portion 3242 to make the wrench rotate around the second connecting pin 3252, and at the same time, the second transmission portion 3241 drives the first transmission portion 3231 to move through the third connecting pin 3253, so that the clamping member 323 rotates around the first connecting pin 3251, thereby driving the clamping member 3232 to be uncoupled from the clamping hoop 322, and making the clamping hoop 322 rotate relative to the support 321 to open the open slot 3211, so as to place the machining head in the open slot 3211 or take the machining head in the open slot 3211.

[0060] To further simplify the operation, in an embodiment, the trigger member 324 is a wrench, so that the worker can directly achieve the locking and releasing functions of the tool by turning the wrench. Alternatively, the trigger member 324 is hinged to the support 321 through a second connecting pin 3252, and the worker turns the wrench around the second connecting pin 3252 to drive the clamping member 323 to move. Figure 3The elastic member 326 is arranged at the joint between the clamping hoop 322 and the support 321, and is used to drive the clamping hoop 322 to move away from the opening slot 3211 when the clamping hoop 322 is separated from the buckling member 323.

[0061] In this way, when the user drives the trigger 324 to drive the buckling member 323 to separate from the clamping hoop 322, the clamping hoop 322 will automatically open the opening slot 3211 under the elastic force of the elastic member 326, without the need for the staff to manually open the clamping hoop 322, further simplifying the operation of the staff and improving the convenience of disassembling and assembling the machining head.

[0062] As an example, the elastic member 326 is a torsion spring.

[0063] In order to further improve the installation reliability of the machining head, in an embodiment, the clamping hoop 322 is provided with a soft rubber pad 3222 on the side wall facing the opening slot 3211. Figure 3 Figure 4 The clamping hoop 322 is provided with a soft rubber pad 3222 on the side wall facing the opening slot 3211.

[0064] By arranging the soft rubber pad 3222, the rigid contact between the clamping hoop 322 and the outer wall of the machining head is avoided, the contact area with the outer wall of the machining head can be increased, the surface pressure can be reduced, and the installation reliability of the machining head can be ensured. At the same time, the soft rubber pad 3222 can also absorb the vibration during the machining of the machining head, prevent the vibration from being transmitted to the clamping hoop 322, and play a certain vibration and noise reduction effect.

[0065] Optionally, the soft rubber pad 3222 can be a rubber pad or a silica gel pad.

[0066] In an embodiment of the present application, the clamping mechanism 320 further comprises a machining head recognition assembly 327 arranged on the support 321, and the machining head recognition assembly 327 is located on one side of the opening slot 3211. Figure 1 Figure 3 Figure 6 Figure 7 The clamping mechanism 320 further comprises a machining head recognition assembly 327 arranged on the support 321, and the machining head recognition assembly 327 is located on one side of the opening slot 3211.

[0067] By arranging the machining head recognition assembly 327 on one side of the opening slot 3211, different types of machining heads can be identified, so that the machining mode or other parameter settings are not matched with the installed machining head.

[0068] Specifically, the machining head recognition assembly 327 comprises at least two mechanical sensors 3271, each mechanical sensor 3271 has a detection pressure rod 3271a which can be pressed; the number of pressed detection pressure rods 3271a corresponds to different types of machining heads.

[0069] ​​​​In actual application, the detection pressure rods 3271a of the mechanical sensor 3271 protrude in the opening slot 3211, when the machining head is installed to the opening slot 3211, different machining heads press different detection pressure rods 3271a correspondingly, so that the type of the machining head can be determined according to the pressing condition of the detection pressure rods 3271a.

[0070] For example, taking the brush 340 and the fine cutter 330 as examples, the outer wall of the brush sleeve of the brush 340 is cylindrical, and the outer shell of the fine cutter 330 is provided with an annular groove 331, so that when the brush 340 is installed to the opening slot 3211, the brush sleeve presses both of the detection pressure rods 3271a, and the machining head is identified as the brush; when the fine cutter 330 is installed to the opening slot 3211, the corresponding detection pressure rod 3271a of the annular groove 331 of the fine cutter shell is not pressed, and among the two detection pressure rods 3271a, one is pressed, and the other is in the original position, and the machining head is identified as the fine cutter.

[0071] In some other embodiments, the machining head recognition assembly 327 can adopt a photoelectric sensor to identify different types of machining heads by infrared photoelectric sensing.
