[0047] The utility model provides a tool 330 is applied to processing equipment, can adjust the length of protruding of the needle of knife, in order to better control the cutting thickness, satisfy the processing thickness demand of different workpieces. 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 and so on. The type of the needle of tool 330 is not limited to a certain specific type, such as can be needle knife, turning tool, hob or other types of tool and so on. The specific structure of tool 330 is explained below.

[0048] In the utility model embodiment, as shown in Figures 1 to 4 The tool 330 includes a tool body 331, a needle assembly 332, and an adjusting mechanism.

[0049] The tool body 331 is provided with a mounting cavity 331a and an outlet 331b communicating with the mounting cavity 331a; the needle assembly 332 is movably arranged in the mounting cavity 331a, and the needle assembly 332 has a needle 3321 that can protrude out of the outlet 331b; the adjusting mechanism is rotatably installed on the tool body 331 and is in transmission connection with the needle assembly 332; rotating the adjusting mechanism can drive the needle assembly 332 to move axially to adjust the length of the needle 3321 protruding out of the outlet 331b; wherein the adjusting mechanism can be fixed in position relative to the tool body 331 when rotated to any position.

[0050] The cutter body 331 serves to support and install components (e.g., the cutter needle assembly 332, the adjusting mechanism) in the cutter 330. The cutter body 331 is provided with a mounting cavity 331a and an extension opening 331b. The cutter needle assembly 332 is installed in the mounting cavity 331a and can move in the mounting cavity 331a, so that the cutter needle 3321 can extend out of the extension opening 331b or retract into the mounting cavity 331a from the extension opening 331b. It can be understood that, when the cutter 330 is shipped, the cutter needle 3321 can be retracted into the mounting cavity 331a to prevent damage to the cutter needle 3321 during transportation or handling. When the cutter 330 needs to be used, the cutter needle 3321 needs to be extended out of the extension opening 331b to contact the workpiece for processing. When the processing requirements of different cutting thicknesses of the workpiece are encountered, the length of the cutter needle 3321 extending out of the extension opening 331b needs to be adjusted to adapt to different processing requirements. Based on this, the adjusting mechanism is rotatably installed on the cutter body 331. The adjusting mechanism is in transmission connection with the cutter needle assembly 332, so that when the adjusting mechanism rotates relative to the cutter body 331, the cutter needle assembly 332 can be driven to move axially in the mounting cavity 331a, and in turn the cutter needle 3321 can be driven to extend out of the extension opening 331b. The adjusting mechanism can be limitingly fixed with the cutter body 331 when rotated to any position. In this way, when the length of the cutter needle 3321 extending out of the extension opening 331b reaches the required length, the rotation of the adjusting mechanism is stopped, so that the adjusting mechanism is fixed with the cutter body 331, and in turn the cutter needle 3321 is kept at the required extension position. In this way, the adjustment purpose of the extension length of the cutter needle 3321 is achieved.

[0051] It should be noted that, in the embodiment, the rotation movement of the adjusting mechanism is used to drive the cutter needle assembly 331 to move axially, and the adjusting mechanism can be limitingly fixed with the cutter body 331 when rotated to any position, so that stepless adjustment of the extension length of the cutter needle 3321 can be achieved. Compared with the gear adjustment mode in the related art, the adjustment of the embodiment is more flexible, the adjustment accuracy is higher, the adjustment range is wider, and the embodiment can be applied to more application scenarios.

[0052] It can be understood that the transmission connection mode of the adjusting mechanism and the cutter needle assembly 332 can be determined according to actual conditions, such as threaded transmission, screw-nut transmission, gear-rack transmission, slider combination transmission or other transmission modes, as long as the adjusting mechanism can drive the cutter needle assembly 332 to move in the mounting cavity 331a. The specific transmission mode is not limited herein.

[0053] In actual application, the adjusting mechanism can be a rotating cap or a handle.

[0054] When the adjusting mechanism is rotated to any position, it can be fixed in position relative to the cutter body 331. It can be understood that the adjusting mechanism and the cutter body 331 have an interference force therebetween. When the adjusting mechanism is not subjected to external force, the adjusting mechanism and the cutter body 331 are relatively fixed through the interference force therebetween. When the adjusting mechanism is subjected to external force to overcome the interference force therebetween, the adjusting mechanism can relatively move with the cutter body 331 to drive the needle 3321 to extend and retract. When the adjusting mechanism is adjusted to the required position, the external force on the adjusting mechanism is released. At this time, the adjusting mechanism is relatively fixed with the cutter body 331 under the action of the interference force, so that the needle 3321 is kept at the position, thereby ensuring the reliability of the position adjustment of the needle 3321 and preventing the needle 3321 from moving.

[0055] In actual application, the interference force between the adjusting mechanism and the cutter body 331 can be realized by increasing the friction force at the matching position of the two, or a damping member can be arranged between the two, or a clamping groove and buckle structure can also be arranged. The specific interference matching mode can be determined according to actual conditions, which is not limited here.

[0056] In summary, in the cutter 330 of the technical scheme of the utility model, the cutter body 331 is provided with a mounting cavity 331a and an extension outlet 331b, a movable needle assembly 332 is mounted in the mounting cavity 331a, the needle assembly 332 has a needle 3321 which can extend out of the extension outlet 331b, a rotatable adjusting mechanism is mounted on the cutter body 331, the adjusting mechanism is in transmission connection with the needle assembly 332, so that when the adjusting mechanism is rotated, the needle assembly 332 can be driven to move axially, and the needle 3321 is driven to extend out of the extension outlet 331b. The adjusting mechanism can be fixed in position relative to the cutter body 331 when rotated to any position, so that the needle 3321 can be kept at the required extension length position, the stepless adjustment function of the extension length of the needle 3321 is realized, the adjustment flexibility of the extension length of the needle 3321 is improved, and the cutting thickness can be better controlled, thereby meeting the processing thickness requirements of different workpieces.

[0057] In an embodiment of the present application, as Figures 2 to 4 The cutter 330 further comprises a damping member 336 connected between the adjusting mechanism and the cutter body 331, so as to interfere with the relative movement of the adjusting mechanism and the cutter body 331.

[0058] By setting the damping member 336 between the adjusting mechanism and the cutter body 331, the interference function between the adjusting mechanism and the cutter body 331 is realized, so that the adjusting mechanism and the cutter body 331 are kept in a relatively fixed state when there is no external force. When it is necessary to adjust the length of the needle 3321, the adjusting mechanism is rotated relative to the cutter body 331 by an external force (such as manual or automatic equipment), which drives the needle assembly 332 to move in the installation cavity 331a to adjust the needle 3321 to the desired position, and then releases the external force acting on the adjusting mechanism. The adjusting mechanism is fixed with the cutter body 331 under the action of the damping member 336, so that the needle 3321 remains in the adjusted position.

[0059] In actual application, the damping member 336 can be a soft member clamped between the adjusting mechanism and the cutter body 331 to buffer the movement of the adjusting mechanism. As an example, the damping member 336 can be a rubber ring, a silica gel ring, etc.

[0060] In order to optionally improve the adjustment flexibility, in an embodiment of the present application, the adjusting mechanism includes an adjusting cap 333 and a transmission member 334, the adjusting cap 333 is sleeved on the outside of the cutter body 331 and threadedly cooperates with the cutter body 331; the damping member 336 is clamped between the inner wall of the adjusting cap 333 and the outer wall of the cutter body 331; the transmission member 334 is movably arranged on the cutter body 331 and transmissionally connects the adjusting cap 333 and the needle assembly 332. Figures 1 to 4

[0061] The adjusting cap 333 serves as a driving member for the rotation operation of the worker, and the transmission member 334 serves to transmit the power of the adjusting cap 333 to the needle assembly 332. The adjusting cap 333 is sleeved on the outside of the cutter body 331 and threadedly cooperates with the cutter body 331 to facilitate the rotation operation of the worker. Optionally, the inner wall of the adjusting cap 333 is provided with a first inner thread 3331, and the outer wall of the cutter body 331 is provided with a first outer thread 33111, the first inner thread 3331 and the first outer thread 33111 threadedly cooperate, so that when the adjusting cap 333 is rotated, the adjusting cap 333 will move axially relative to the cutter body 331, and then the transmission member 334 can be axially moved, so that the needle assembly 332 is axially moved, realizing the function of converting the rotation movement of the adjusting cap 333 into the axial movement of the needle 3321.

[0062] Optionally, anti-slip patterns 3333 can be provided on the outer wall of the adjusting cap 333 to facilitate the operation of the worker.

[0063] ​The damping member 336 is clamped between the inner wall of the adjusting cap 333 and the outer wall of the cutter body 331, and can be understood as interfering with the relative movement of the adjusting cap 333 and the cutter body 331. As an example, the damping member 336 is a sealing ring, and the outer wall of the cutter body 331 is provided with a mounting groove 331d, and the sealing ring is mounted in the mounting groove 331d and abuts against the inner wall of the adjusting cap 333. In this way, the adjusting cap 333 will always press the sealing ring during rotation, so that the adjusting cap 333 can be fixed relative to the cutter body 331 when rotated to any position, achieving the purpose of stepless rotary adjustment.

[0064] In actual application, the specific structure of the transmission member 334 can be determined according to actual conditions, such as a cylindrical structure, a block structure or a rod structure, etc. As long as it can ensure that the power of the adjusting cap 333 is transmitted to the cutter needle assembly 332.

[0065] As an example, one end of the transmission member 334 extends into the mounting cavity 331a to abut against the cutter needle assembly 332, and the other end of the transmission member 334 is arranged outside the cutter body 331 to be in transmission connection with the adjusting cap 333.

[0066] It can be understood that the cutter needle assembly 332 is located inside the cutter body 331, and the adjusting cap 333 is located outside the cutter body 331. By connecting one end of the transmission member 334 to the cutter needle assembly 332 by extending into the mounting cavity 331a, and connecting the other end of the transmission member 334 to the adjusting cap 333 outside the cutter body 331, the operator can rotate the adjusting cap 333 outside to adjust the length of the cutter needle 3321 to extend, simplifying the adjustment operation of the operator.

[0067] Optionally, as Figures 2 to 4 , the transmission member 334 is in a cylindrical structure; the outer wall of the cutter needle assembly 332 is provided with a limiting surface 33221, the transmission member 334 is sleeved outside the cutter needle assembly 332 and abuts against the limiting surface 33221; and one end of the transmission member 334 away from the limiting surface 33221 is arranged in the adjusting cap 333 and is in threaded connection with the adjusting cap 333.

[0068] The outer wall of the cutter needle assembly 332 is provided with a limiting surface 33221, and the transmission member 334 is sleeved outside the cutter needle assembly 332 so that the end of the transmission member 334 abuts against the limiting surface 33221, so that when the transmission member 334 moves axially, the cutter needle assembly 332 can be pushed to move axially. One end of the transmission member 334 away from the limiting surface 33221 extends out of the cutter body 331 and is in connection with the adjusting cap 333, so that when the adjusting cap 333 rotates, the transmission member 334 can be driven to move axially, achieving the function of driving the cutter needle assembly 332 to move axially.

[0069] The transmission member 334 is arranged in the interior of the adjusting cap 333, and the outer wall of the transmission member 334 is optionally provided with a second external thread 3341, and the inner wall of the adjusting cap 333 is provided with a second internal thread 3332, and the two are connected through the threaded cooperation of the second external thread 3341 and the second internal thread 3332.

[0070] It can be understood that the cutter 330 can be adjusted to an initial position (for example, a position flush with the plane of the outlet 331b) when it is shipped from the factory, so as to facilitate subsequent adjustment of the staff to the length of the needle 3321. When the lengths of different needles 3321 are different, the transmission member 334 can be adjusted to drive the needle assembly 332 to move, so that the different length needles 3321 are moved to the initial position (for example, a position flush with the plane of the outlet 331b), so as to eliminate the influence of different length needles 3321 and realize the factory calibration function.

[0071] Optionally, as Figures 2 to 4 , the adjusting mechanism further comprises a locking member 335 for limiting the relative movement of the transmission member 334 and the adjusting cap 333.

[0072] As can be seen from the foregoing embodiments, the transmission member 334 is in threaded cooperation with the adjusting cap 333, so that when the adjusting cap 333 is rotated, the transmission member 334 will move relative to the adjusting cap 333. After the transmission member 334 adjusts the needle 3321 to the initial position (i.e. factory calibration), the transmission member 334 and the adjusting cap 333 are locked and fixed by the locking member 335, so that the transmission member 334 can rotate together with the adjusting cap 333. At this time, the transmission member 334 and the adjusting cap 333 can be equivalent to a whole structure, and when they rotate relative to the cutter body 331, they can directly transmit the power of the adjusting cap 333 to the needle assembly 332, reducing the loss of intermediate power transmission and improving the adjustment accuracy.

[0073] Optionally, the locking member 335 is a screw.

[0074] In an embodiment of the present application, as Figures 2 to 4 , the cutter 330 further comprises a limiting ball 337, the outer wall of the cutter body 331 is provided with a limiting hole 331c, and the inner circumferential wall of the adjusting cap 333 is provided with an annular clamping groove 333a, the limiting ball 337 is clamped in the limiting hole 331c and is in sliding cooperation with the annular clamping groove 333a; the axial width of the annular clamping groove 333a is greater than the diameter of the limiting ball 337, so that the adjusting cap 333 can move axially relative to the limiting ball 337.

[0075] In the embodiment, the limiting hole 331c is arranged on the outer wall of the cutter body 331, the annular clamping groove 333a is arranged on the inner wall of the adjusting cap 333, and the limiting ball 337 is clamped in the limiting hole 331c. When the adjusting cap 333 is sleeved on the cutter body 331, the limiting ball 337 can be clamped in the annular clamping groove 333a, so as to limit the axial movement of the adjusting cap 333. Specifically, the axial width of the annular clamping groove 333a is greater than the diameter of the limiting ball 337, so that when the adjusting cap 333 rotates circumferentially relative to the cutter body 331, the axial ends of the annular clamping groove 333a are respectively abutted with the limiting ball 337, thereby realizing the stroke limiting function of the adjusting cap 333 in the axial direction.

[0076] Optionally, as Figures 2 to 4 , the limiting hole 331c is a through hole penetrating through the side wall of the cutter body 331, and the side of the limiting ball 337 away from the annular clamping groove 333a abuts against the transmission member 334.

[0077] During installation, the limiting ball 337 is first installed in the limiting hole 331c from the outside, then the adjusting cap 333 is installed on the cutter body 331, the inner wall of the adjusting cap 333 covers the limiting ball 337 to prevent the limiting ball 337 from falling out of the limiting hole 331c from the outside, and then the transmission member 334 is inserted into the cutter body 331. During installation of the transmission member 334 towards the needle 3321, the side wall of the transmission member 334 pushes the limiting ball 337 to the annular clamping groove 333a, so that the limiting ball 337 is clamped in the limiting hole 331c and the annular clamping groove 333a, thereby realizing installation of the limiting ball 337.

[0078] In order to optionally improve the installation reliability of the limiting ball 337, the end of the transmission member 334 is provided with a guide surface 3342, which is arranged in a slope, so as to push the limiting ball 337 to the annular clamping groove 333a.

[0079] In an embodiment of the application, as Figures 1 to 2 , the outer peripheral wall of the cutter body 331 is provided with a scale mark groove 331e, and the adjusting cap 333 is provided with an open window 333b corresponding to the scale mark groove 331e.

[0080] By arranging the scale mark groove 331e and the open window 333b, the worker can rotate the adjusting cap 333 according to the scale mark, and can directly judge the length of the needle 3321 extending out by the mark of the scale mark groove 331e, which optionally improves the operation convenience of the worker.

[0081] In an embodiment of the application, as Figures 2 to 4The needle assembly 332 further comprises a thimble 3322, a sliding sleeve 3323, a magnetic member 3324 and an elastic member 3325. The thimble 3322 is arranged in the installation cavity 331a and extends out of the one end of the cutter main body 331 away from the outlet 331b. The adjusting mechanism is in transmission connection with the thimble 3322. The sliding sleeve 3323 is arranged in the installation cavity 331a and is in connection with the thimble 3322 and the needle 3321 at the two axial ends thereof. The magnetic member 3324 is arranged in the sliding sleeve 3323 and is used for magnetically attracting the needle 3321. The elastic member 3325 is sleeved on the outside of the needle 3321 and is used for providing a driving force for the movement of the sliding sleeve 3323 away from the outlet 331b.

[0082] The structure of the needle assembly 332 is illustrated in the embodiment. The thimble 3322 is in transmission connection with the adjusting mechanism and is used for driving the axial movement of the needle 3321. The sliding sleeve 3323 is used for connecting the thimble 3322 and the needle 3321. The elastic member 3325 is sleeved on the outside of the needle 3321. The elastic member 3325 can provide an elastic force for the sliding sleeve 3323 away from the outlet 331b. The thimble 3322 abuts against the sliding sleeve 3323 towards the outlet 331b to limit the position of the sliding sleeve 3323 in the installation cavity 331a, thereby controlling the position of the needle 3321.

[0083] In actual application, when the adjusting cap 333 is rotated, the transmission member 334 can drive the thimble 3322 to move towards the outlet 331b, thereby driving the sliding sleeve 3323 to move towards the outlet 331b to push the needle 3321 to extend out of the outlet 331b. At this time, the elastic member 3325 is compressed. When the adjusting cap 333 is reversely rotated to drive the transmission member 344 to move away from the outlet 331b, the sliding sleeve 3323 moves away from the outlet 331b under the elastic restoring force of the elastic member 3325, thereby driving the thimble 3322 to move away from the outlet 331b to abut against the transmission member 344. At this time, the needle 3321 moves away from the outlet 331b under the magnetic attraction force of the magnetic member 3324 to shorten the extension length of the needle 3321. In this way, the extension length of the needle 3321 can be adjusted by rotating the adjusting cap 333.

[0084] Optionally, in some embodiments, as shown in FIG. 6, the two ends of the needle 3321 are respectively provided with bearings 3326. One bearing 3326 is arranged in the sliding sleeve 3323 and the other bearing 3326 is arranged in the cutter main body 331. The elastic member 3325 is arranged between the two bearings 3326.

[0085] It can be understood that the two bearings 3326 support the two ends of the needle 3321. One bearing 3326 is mounted on the sleeve 3323, and the bearing 3326 can move axially with the sleeve 3323 to push the needle 3321 to move axially. The other bearing 3326 is mounted on the tool body 331, and the needle 3321 can pass through the bearing 3326 to move in and out.

[0086] Optionally, the elastic member 3325 is a spring, and the two ends are connected to the two bearings 3326, respectively.

Specifically, the tool head cap 3312 abuts and limits the bearing 3326 installed on the tool body 331. The extension port 331b on the tool head cap 3312 is coaxial with the inner hole of the bearing 3326, so that the needle 3321 can be extended from the extension port 331b.

[0089] Optionally, the tool head cap 3312 is in interference fit with the sleeve rod 331.

[0090] Optionally, the end surface of the tool head cap 3312 away from the sleeve rod 3311 is a plane. In this way, the initial position of the tip of the needle 3321 can be aligned with the end surface of the tool head cap 3312 when the tool 330 is shipped. By using the plane end surface as a reference for alignment, the difficulty of calibration when shipped can be optionally reduced, and the lift efficiency can be improved.
