The content recorded therein is considered to be a part of the disclosure of this application, and a part of its content is hereby incorporated by reference. Technical field
[0003] The utility model relates to the technical field of electronic cutting machines, specifically to cutting components and electronic cutting machines. Background art

[0005] The cutting assembly generally includes a support assembly, a tool support frame, and a driver. The tool support frame is structured with a tool clamping mechanism. Among them, the support assembly can move horizontally along a guide rod, the tool support frame can move vertically relative to the support assembly, and the tool clamping mechanism is used to fix the working tool.
[0006] The cutting component of the manufacturing device assembly disclosed in the patent document CN111065500A includes a support member, a support member moving device, a spring, and a motor. The support member is movably connected to a support rod, the support member moving device is connected to the support member, and the spring acts on the support member moving device and the support member. The support member moving device includes a rack and pinion transmission mechanism. The spring includes two non-linear springs and a balance spring, and the motor is coupled to the rack and pinion transmission mechanism. Such a cutting component has deficiencies such as complex mechanism, poor stability, high production and assembly costs, and large volume. Summary of the invention
[0007] An object of this application is to overcome the deficiencies of the existing cutting components, such as complex mechanism, poor stability, high production and assembly costs, and large volume. This is solved by driving the working tool with a screw-nut mechanism and elastically transmitting the driving force through an elastic coupling member.
[0008] The technical solution adopted in this application is as follows:
[0009] Cutting component, including a support, a support member, a tool holding mechanism, a motor, and a drive connection member; the support member is movably connected to the support, the tool holding mechanism is configured on the support member for mounting a working tool, the motor is mounted on the support for driving the support member; the drive connection member includes a lead screw portion directly configured or at least indirectly connected to the output shaft of the motor, a nut member assembled on the lead screw portion, and one or more elastic coupling members connecting the nut member and the support member; the motor drives the working tool to move relative to the support through the drive connection member, and when driving the working tool along the working direction, the driving force is elastically transmitted by the elastic coupling member.
[0010] This application uses a lead screw and nut mechanism to drive the working tool, with a simple structure, stable and reliable operation, fast response, good economy. When driving the working tool along the working direction, the driving force is elastically transmitted by the elastic coupling member, which can ensure the control and adjustment of the cutting force between the working tool and the workpiece, simplify the number and installation structure of the elastic elements, and achieve stable control.
[0011] Further, the elastic coupling member includes a connecting member and a spring. The support member is connected to the nut member through the connecting member, and the support member can move relative to the connecting member with a limited stroke. The spring is installed on the connecting member and acts on the support member and the nut member. The connecting member plays a role in connection and guiding, and also plays a role in force transmission when lifting the working tool. The spring installed on the connecting member can well define its position so that it can transmit elastic drive to the support member.
[0012] Further, the support member is provided with a drive base, the drive base is provided with a movable hole, the lead screw portion passes through the movable hole and is screwed to the nut member, the connecting member connects the side of the drive base and the nut member, and the support member can move relative to the connecting member with a limited stroke. The spring is installed on the connecting member and acts on the drive base and the nut member. The structure of the drive base facilitates the installation of the drive connection member and receives the elastic force transmission of the spring to provide the stability and buffering function of the structure and optimize the structure layout; the connecting member connecting the side of the drive base and the nut member can position and guide the nut member.
[0013] Further, a reinforcing member is fixedly connected to the upper side of the drive base, the connecting member connects the reinforcing member and the nut member, and the spring acts on the drive base and the nut member. The reinforcing member can increase the structural strength of the drive base, optimize the acting forces generated by the working tool and the motor on the drive base, and improve the stability of the support member.
[0014] Furthermore, the driving base is integrally formed horizontally on the upper part of the supporting member, and the motor is arranged in the lower space of the driving base with the output shaft facing upward. The integral horizontal formation of the driving base and the upper part of the supporting member ensures a stable structure and simplifies the production process, such as by using integral forming methods like injection molding. With the motor output shaft facing upward, it can be compactly arranged under the driving base, achieving efficient use of space.
[0015] Furthermore, the tool holding mechanism is constructed on the front side of the lower end of the supporting member. The arrangement of the tool holding mechanism and the driving base enables better transmission of the driving force of the motor, improving the response efficiency.
[0016] Furthermore, the supporting member includes a vertically extending supporting member body. The driving base is constructed on the upper rear side of the supporting member body, and the width of the supporting member body is at least two-thirds of the width of the support base. The width design of the supporting member body blocks the connection structure between the supporting member and the support base, making the front surface of the cutting component neat and beautiful.
[0017] Furthermore, the support base includes a support base body with a motor installation area constructed thereon, and a support base cover installed on the upper side of the support base body for fixing the motor. The support base body is constructed with a guiding installation channel perpendicular to the movement direction of the supporting member. With the above structure, it is convenient for the stable installation of the motor, and at the same time, the structure is compact and simple.
[0018] Furthermore, the tool holding mechanism includes a clamping seat, a locking control, and a connecting rod member. The clamping seat has a clamping channel communicating the upper end and the lower end, and a coupling groove penetrating the side wall of the clamping seat and the clamping channel. The side wall of the clamping seat located at a preset distance from the first side of the coupling groove is constructed with an elastic deformation portion. The connecting end of the locking control is hinged to the first side of the coupling groove of the clamping seat, so that the locking control can approach or move away from the outside of the clamping seat. The connecting rod member is respectively hinged to the second side of the coupling groove and near the connecting end of the locking control. By controlling the locking control to approach or move away from the clamping seat, the position of the first side of the coupling groove relative to the second side is changed, causing the elastic deformation portion of the clamping seat to elastically deform and change the inner diameter of the clamping channel, thereby realizing the clamping or release of the tool. The tool holding mechanism realizes the clamping or release of the tool by constructing an elastic deformation portion on the side wall of the clamping seat at a preset position relative to the coupling groove, and by controlling the locking control to utilize the elastic deformation characteristics of the elastic deformation portion to change the inner diameter of the clamping channel, reducing the parts of the tool holding mechanism and simplifying the structure.

[0037] The present application generally relates to a cutting component a and an electronic cutting machine, such as Figure 17An embodiment of the present application is shown, which includes that the electronic cutting machine main body 7 is provided with a working area 700, the cutting component a is installed on the working area 700 through the first guide rod 701 and the second guide rod 702, the cutting component a is in transmission connection with a driving mechanism (not shown) inside the main machine 7 through a transmission belt 705, the driving mechanism drives the cutting component a to reciprocate along the first guide rod 701 and the second guide rod 702 through the transmission belt 705. The driving mechanism (not shown) is not an improvement content of the present application and will not be specifically described. Door structures for opening or closing the working area 700 are respectively arranged on the front side and the upper side of the main machine 7.
[0038] See Figures 1 to 6 , the cutting component a of the present application includes: a support 5, a support member 4, a tool holding mechanism 1', a motor m and a driving connection member m'; the support member 4 is movably connected to the support 5, the tool holding mechanism 1' is constructed on the support member 4 for installing a working tool n, the motor m is installed on the support 5 for driving the support member 4; the driving connection member m' includes a lead screw portion m.11 directly constructed or at least indirectly connected to the output shaft m.1 of the motor, a nut member m.2 assembled on the lead screw portion m.11, and one or more elastic coupling members m.3 connecting the nut member m.2 and the support member 4; the motor m drives the working tool n to move relative to the support 5 through the driving connection member m', and when driving the working tool n along the working direction, the driving force is elastically transmitted by the elastic coupling member m.3.
[0039] The working tool n can be a cutting tool, such as Figures 1 to 6 shown, and of course it can also be other tools used in combination, such as a drawing pen.
[0040] Such as Figure 5 shown, the lead screw portion m.11 is a threaded portion directly constructed on the output shaft m.1 of the motor. For example, the lead screw portion m.11 and the output shaft m.1 of the motor are an integral structure. This structure has no intermediate connecting member, high precision, good stability and compact structure. Of course, in other embodiments, the lead screw portion m.11 and the output shaft m.1 of the motor are integrally formed by welding. In some other embodiments, the lead screw portion m.11 and the output shaft m.1 of the motor are two components and are connected through a connecting member, such as a screw, a keyway fit and other well-known connection methods.
[0041] Such as Figures 4 to 6 shown, the support member 4 is movably connected to the support 5 through a guide rod 4.2.
[0042] The motor m is a stepper motor, a servo motor, or other well-known motors. The drive control of the motor m is not an improvement of the present application, and those skilled in the art can achieve it through the control means of the prior art.
[0043] This application uses a lead screw nut mechanism to drive the working tool n. The mechanism is simple, stable and reliable, with fast response and good economy. When driving the working tool n along the working direction, the driving force is elastically transmitted by the elastic coupling member m.3, which can ensure the control and adjustment of the cutting force between the working tool n and the workpiece, simplify the number and installation structure of elastic elements, and achieve stable control.
[0044] See Figures 1 to 6 , the elastic coupling member m.3 includes a connecting member m.311 and a spring m.32. The support member 4 is connected to the nut member m.2 through the connecting member m.311, and the support member 4 can move relative to the connecting member m.31 with a limited stroke. The spring m.32 is installed on the connecting member m.311 and acts on the support member 4 and the nut member m.2. The connecting member m.31 plays a role of connection and guidance, and also plays a role of force transmission when lifting the working tool n. The spring m.32 installed on the connecting member m.311 can well limit its position so as to transmit elastic drive to the support member 4.
[0045] Specifically, in one embodiment, the connecting member m.31 can movably pass through the lower end of the flange hole of the nut member m.2 to connect the support member 4, and a limiting structure for preventing the nut member m.2 from disengaging is provided on the upper side of the flange hole m.21 of the nut member m.2.
[0046] One embodiment of the connecting member m.31 is a bolt, and the bolt is threadedly connected to the support member 4, that is, the support member 4 is provided with a threaded hole for connecting with the bolt. When lifting the working tool n, the head of the bolt limits the highest moving position of the support member 4 and transmits the lifting force. That is, when lifting the working tool n, the motor m drives the nut member m.2 to move upward. When the nut member m.2 abuts against the head of the bolt, the support member 4 is driven to lift.
[0047] In other embodiments, the connecting member m.31 can also be a connecting column. The connecting column is separately connected to the support member 4, such as threaded connection, fitting connection (such as interference fitting), or the connecting column is integrally connected to the support member 4, such as integrally formed, welded, etc. The connecting column passes through the upper side of the flange hole m.21 of the nut member m.2 and is connected to the upper end of the connecting column through a limiting terminal, such as a nut, a pin, etc.
[0048] In Figures 1 to 6 the illustrated embodiment, three elastic coupling members m.3 are configured and arranged at intervals along the circumference around the axis of the lead screw portion m.11. Three can ensure good force stability. Of course, in other embodiments, the number can be other values, such as two or more than four. The connection stability between the overall support member 4 and the nut member m.2 is good.
[0049] See Figures 1 to 7, the support member 4 is provided with a driving base 4.1. The driving base 4.1 is provided with a movable hole 4.10. The lead screw portion m.11 passes through the movable hole 4.10 and is screwed to the nut member m.2. The connecting member m.31 connects the flange hole m.21 on the side of the driving base 4.1 and the nut member m.2, and the support member 4 can move relative to the connecting member m.31 with a limited stroke. The spring m.32 is installed on the connecting member m.31 and acts on the driving base 4.1 and the nut member m.2. The structure of the driving base 4.1 facilitates the installation of the driving connection member m', and accepts the elastic force transmission of the spring m.32 to provide the structural stability and buffering function, and optimize the structural layout; the connecting member m.31 connecting the side of the driving base 4.1 and the nut member m.2 can position and guide the nut member m.2.
[0050] A reinforcing member m.5 is fixedly connected to the upper side of the driving base 4.1. The connecting member m.31 connects the reinforcing member m.5 and the nut member m.2, and the spring m.32 acts on the driving base 4.1 and the nut member m.2. The reinforcing member m.5 can increase the structural strength of the driving base 4.1, optimize the acting force generated by the working tool n and the motor m on the driving base 4.1, and improve the stability of the support member 4. The reinforcing member m.5 and the driving base 4.1 can be connected by connecting members such as screws.
[0051] See Figures 1 to 4 and Figure 7 , the side of the driving base 4.1 is provided with a reinforcing wall 4.11 extending upward. The inner side of the reinforcing wall 4.11 is constructed into a space 4.11 for installing the reinforcing member m.5.
[0052] In one embodiment, the surface of the driving base 4.1 is flat, and the reinforcing member m.5 is plate-shaped.
[0053] In one embodiment, the support member 4 is injection-molded, and the reinforcing member m.5 is a metal part. With this structure, the support member 4 is easy to manufacture, and the reinforcing member m.5 can ensure the structural strength and stability of the driving base 4.1.
[0054] The driving base 4.1 is integrally formed horizontally on the upper part of the support member 4. The motor m is arranged in the lower space of the driving base 4.1 with the output shaft m.1 facing upward. The horizontal integral molding of the driving base 4.1 and the upper part of the support member 4 ensures the structural stability and simplifies the production process, such as integral molding such as injection molding; the output shaft m.1 of the motor m is compactly arranged upward on the lower side of the driving base 4.1 to achieve efficient use of space.
[0055] The tool holding mechanism 1' is constructed on the front side of the lower end of the support member 4. The arrangement of the tool holding mechanism 1' and the driving base 4.1 can make the driving force of the motor m be transmitted better and improve the response efficiency.
[0056] See Figures 1 to 7 , the support member 4 includes a vertically extending support member body 4', the drive base 4.1 is constructed at the upper rear side of the support member body 4', and the width of the support member body 4' is at least two-thirds of the width of the support 5. The width of the support member body 4' is designed to block the connection structure between the support member 4 and the support 5, making the front side surface of the cutting member neat and beautiful.
[0057] See Figures 1 to 6 , the support 5 includes a support body 5.1 constructed with a motor installation area 500, and a support cover 5.2 installed on the upper side of the support body 5.1 for fixing the motor m. The support body 5.1 is constructed with guiding installation channels 501 and 502 perpendicular to the movement direction of the support member 4. With the above structure, it is convenient for the stable installation of the motor m, and at the same time, the structure is compact and simple.
[0058] See Figures 2 to 7 , a guiding assembly hole 4.20 is provided at the rear side of the support member body 4', and the guiding assembly hole 4.20 is slidably connected through a guiding rod 4.2. Of course, in order to ensure the sliding fit, a sliding sleeve 4.3 cooperating with the guiding rod 4.2 is installed in the guiding assembly hole 4.20.
[0059] In an embodiment, two groups of guiding assembly holes 4.20 and guiding rods 4.2 are provided.
[0060] As Figures 5 to 7 shown, the lower end of the guiding rod 4.2 is installed at the guiding rod installation part 5.11 of the support body 5.1, and the upper end is installed at the support cover 5.2. An avoidance hole 4.12 corresponding to the guiding rod 4.2 is provided on the drive base 4.1.
[0061] As Figure 5 and Figure 7 shown, a position detection element s1 for detecting the position of the support member 4 is installed on the front side of the support body 5.1, and a triggering part s2 for triggering the detection element s1 is correspondingly provided at the rear side of the support member body 4'. The position detection element s1 is a prior art.
[0062] See Figures 8 to 16, the tool holding mechanism 1' of the present application includes: a clamping seat 1, a locking control 2 and a link member 3; the clamping seat 1 has a clamping channel 100 communicating the upper and lower ends, and a coupling groove 10 penetrating the side wall of the clamping seat 1 and the clamping channel 100. An elastic deformation portion 10' is formed on the side wall of the clamping seat 1 at a preset distance from the first side 101 of the coupling groove 10; the connecting end of the locking control 2 is hinged to the first side 101 of the coupling groove 10 of the clamping seat 1, so that the locking control 2 can approach or move away from the outside of the clamping seat 1; the link member 3 is respectively hinged to the second side 102 of the coupling groove 10 and the vicinity of the connecting end of the locking control 2; by controlling the locking control to approach or move away from the outside of the clamping seat 1, the position of the first side 101 of the coupling groove 10 relative to the second side 102 is changed, so that the elastic deformation portion 10' of the clamping seat 1 undergoes elastic deformation to change the inner diameter of the clamping channel 100, realizing the clamping or release of the tool.
[0063] Specifically, when the locking control 2 is turned towards the clamping seat 1, the side of the clamping seat 1 close to the coupling groove 10 is pulled, so that the elastic deformation portion 10' undergoes elastic deformation to reduce the inner diameter of the clamping channel 100, realizing the clamping of the working tool n. When the locking control 2 is turned away from the clamping seat 1, the elastic deformation portion 10' is released, so as to restore the normal state of the clamping channel 100 and release the clamping of the working tool n. The user can install or remove the tool n from above.
[0064] The tool holding mechanism 1' forms an elastic deformation portion 10' on the side wall of the clamping seat 1 at a preset distance from the coupling groove 10. By controlling the locking control 2 and utilizing the elastic deformation characteristics of the elastic deformation portion 10', the inner diameter of the clamping channel 100 is changed to realize the clamping or release of the tool, reducing the parts of the tool holding mechanism and simplifying the structure.
[0065] In order to realize the locking of the locking control 2, the hinge axis of the connecting end of the locking control 2 and the clamping seat 1 is ax1, the hinge axis of the link member 3 and the second side 102 is ax2, and the hinge axis of the link member 3 and the locking control 2 is ax3. Among them, the hinge axis ax3 is closer to the free end of the locking control 2 than the hinge axis ax1. In this way, when the locking control 2 approaches the clamping seat 1, the effect of self-locking can be realized, preventing the locking control 2 from moving to release the tool.
[0066] Such as Figure 8 and Figure 9As shown, the elastic deformation part 10' is located on the side wall of the clamping seat 1 opposite to the coupling groove 10. In this application, "the side wall of the clamping seat 1 located at a preset distance from the coupling groove 10 is configured with the elastic deformation part 10'" means that the distance between the elastic deformation part 10' and the coupling groove 10 can ensure that the part of the clamping seat 1 on the first side (101) of the coupling groove 10 can be manipulated by the locking control 2 to force the elastic deformation part 10' to undergo elastic deformation, so that the first side 101 of the coupling groove 10 moves relative to the second side 102, changing the inner diameter of the clamping channel 100. It can be easily understood that the greater the distance between the elastic deformation part 10' and the first side 101 of the coupling groove 10, the easier the elastic deformation of the elastic deformation part 10'. However, since the clamping seat 1 is connected to the tool support member 4 of the cutting member a, the maximum position is the position adjacent to the tool support member 4. The preferred position is that the elastic deformation part 10' is arranged at the position directly opposite to the coupling groove 10 and adjacent to the directly opposite position. Of course, as described above, the position where the elastic deformation part 10' of this application is provided is not limited to the above-mentioned preferred position, as long as it satisfies "it can ensure that the part of the clamping seat 1 on the first side (101) of the coupling groove 10 can be manipulated by the locking control 2 to force the elastic deformation part 10' to undergo elastic deformation, so that the first side 101 of the coupling groove 10 moves relative to the second side 102".
[0067] In some embodiments, the connecting end of the locking control 2 is provided with a first hinge groove 1011, and the connecting rod member 3 is hinged in the first hinge groove 1011, such as by a pin shaft. The second side 102 is provided with a second hinge groove 1021, and the other end of the connecting rod member 3 is hinged in the second hinge groove 1021, such as by a pin shaft. With the above structure, the structure of the tool holding mechanism is made compact and simple.
[0068] In some embodiments, the outer side of the clamping seat 1 adjacent to the locking control 2 is configured to be arc-shaped, and the part of the locking control 2 that cooperates with it is also arc-shaped. In this way, the locking control 2 can be closer to the locking control 2 to ensure the clamping force on the tool, and at the same time, better utilize the dead swing position of the locking control 2 to achieve self-locking. At the same time, it has both aesthetic appearance and reduces space occupation.
[0069] In some embodiments, a concave position 103 is configured on the surface of the clamping seat 1 close to (in the clamping state) the degree of freedom of the locking control 2, and the free end of the locking control 2 does not closely adhere to the clamping seat 1 to facilitate the user's finger to manipulate the locking control 2.
[0070] In some embodiments, a vertical notch groove 100' is configured on the inner side of the clamping seat 1, and the wall body of the notch groove 100 is configured as at least a part of the elastic deformation part 10', making the elastic deformation of this part greater by using a simple structure to reduce the wall thickness.
[0071] As attached Figure 8 and Figure 9As shown, in some embodiments, the cross-section of the notch groove 100' is U-shaped. Adopting this shape structure can optimize the force when the notch groove 100' is squeezed, and will not cause excessive local force and fracture.
[0072] Of course, in some embodiments, no notch groove 100' is provided on the inner side of the elastic deformation part 10', as long as the material for manufacturing the elastic deformation part 10' meets the elastic requirements.
[0073] In some embodiments, the elastic deformation part 10' is formed by reducing the thickness of the side wall of the clamping seat 1, that is, the thickness of the side wall of this part is smaller than that of the adjacent part, so that the elastic deformation of this part is larger than that of the adjacent part.
[0074] See Figure 8 、 Figure 9 and Figure 10 , in some embodiments, the clamping seat 1 and the tool support member 4 of the cutting member a are integrated. For example, they are integrally formed with plastic or metal materials.
[0075] Of course, in other embodiments, the clamping seat 1 and the tool support member 4 are manufactured separately and then connected together through a connecting member such as a screw or a connecting process such as welding.
[0076] In some embodiments, a clamping part for increasing adhesion is arranged inside the clamping seat 1, and the clamping part contacts at least a part of the tool n; the clamping part is specifically one or more flexible strips, protrusions, etc., such as made of silica gel or rubber, and is fixed inside the clamping seat 1 by means of a connecting member such as a screw, an adhesive, an inlay, etc. The clamping part plays a role in clamping the tool n to prevent the tool from moving upward during operation.
[0077] In some other embodiments, a plurality of vertical fitting grooves are provided inside the clamping seat 1, and a flexible clamping strip (not shown in the figure) is assembled in the fitting grooves, and the flexible clamping strip protrudes from the inner surface of the clamping seat 1.
[0078] The fitting groove is provided with a radial limiting structure, referring to the dovetail groove structure shown in Figure 6 or the T-shaped groove structure.
[0079] Of course, for the convenience of assembly, the fitting groove communicates with at least one end of the clamping seat 1 at least.
[0080] In a preferred embodiment, the upper end of the fitting groove is non-open, because during use, the force of the tool on the clamping part is upward, which can limit the upward movement of the flexible clamping strip.
[0081] In Figures 10 to 10In the shown solution, a flexible interlayer 104 is arranged inside the clamping seat 1, and the interior of the flexible interlayer 104 constitutes the clamping channel 100. The flexible interlayer 104 can be made of materials such as silica gel, rubber, resin materials, etc. that can increase the clamping friction. The flexible interlayer 104 plays a role in better clamping the tool n and preventing the tool from moving upward during operation.
[0082] In some embodiments, a number of limiting protrusions (not shown) are configured on the inner side of the flexible interlayer 104. The limiting protrusions can be a number of spaced-apart limiting ribs, bumps, or special-shaped protrusions, etc. The limiting protrusions play an effect of increasing the clamping friction.
[0083] In some embodiments, the clamping seat 1 is made of plastic material, and the flexible interlayer 104 is formed in the clamping seat 1 by secondary injection molding. Of course, it can also be made separately and then assembled.
[0084] An embedding groove 105 for positioning the flexible interlayer 104 can be configured on the clamping seat 1, which can prevent the flexible interlayer 104 from rotating. In some embodiments, the embedding groove 105 is configured with a radial limiting structure, such as Figure 13 the shown dovetail groove structure, or the T-shaped groove structure. When the flexible interlayer 104 is injection molded, a limiting rib structure 1042 is filled at the embedding groove 105.
[0085] Such as Figure 13 shown, in some embodiments, when the flexible interlayer 104 is injection molded, a notch filling portion 1041 is filled at the notch groove 100’. The notch filling portion 1041 plays a role in blocking the notch groove 100’ and does not affect the elastic deformation of the elastic deformation portion 10’.
[0086] See Figures 10 to 12 , a limiting step 104’ is arranged at the upper part of the inner side of the clamping seat 1, and the flexible interlayer 104 is injection molded under the limiting step 104’. Of course, the notch groove 100’ penetrates through the limiting step 104’, and the notch filling portion 1041 extends along the notch groove 100’ above the limiting step 104’.
[0087] In other embodiments, one or more flexible clamping portions (not shown in the figure) can be arranged on the side wall of the clamping channel 100.
[0088] See Figures 14 to 16, Another implementation of the tool holding mechanism provided by the present application includes a clamping seat 1, a locking control 2, and a link member 3; the clamping seat 1 has a clamping channel 100 communicating the upper and lower ends, and coupling portions 10a vertically extending to the upper and lower sides of the side wall of the clamping seat 1. The side wall of the clamping seat 1 located at a preset distance from the coupling portion 10a is configured with an elastic deformation portion 10'; the connecting end of the locking control 2 is hinged to the first side 101' of the coupling portion 10a of the clamping seat 1, so that the locking control 2 can approach or move away from the outside of the clamping seat 1; the link member 3 is respectively hinged to the second side 102 of the coupling portion 10a and near the connecting end of the locking control 2; by controlling the locking control to approach or move away from the clamping seat 1, the elastic deformation portion 10' of the clamping seat 1 undergoes elastic deformation to change the inner diameter of the clamping channel 100, realizing tool clamping or release. The coupling portion 10a receives the position change of the first side 101' when the inner diameter of the clamping channel 100 changes.
[0089] Specifically, when the locking control 2 is turned towards the direction of approaching the clamping seat 1, the side of the clamping seat 1 near the coupling portion 10a is pulled, so that the elastic deformation portion 10' undergoes elastic deformation to reduce the inner diameter of the clamping channel 100, realizing the clamping of the tool n. When the locking control 2 is turned away from the direction of approaching the clamping seat 1, the elastic deformation portion 10' is released, so as to restore the normal state of the clamping channel 100 and release the clamping of the tool n. The user can install or remove the tool n from above. In this implementation, the position setting of the elastic deformation portion 10' relative to the coupling portion 10a is the same as the setting requirement of the elastic deformation portion 10' relative to the coupling groove 10 in the present application. Specifically, the relevant content of the elastic deformation portion 10' relative to the coupling groove 10 can be referred to.
[0090] The connection manner of the locking control 2 with the link member 3 and the clamping seat 1 is the same as or similar to the connection manner in other embodiments of the present application.
[0091] The tool holding mechanism realizes tool clamping or release by constructing an elastic deformation portion 10' on the side wall of the clamping seat 1 located at a preset distance from the coupling portion 10a, and by controlling the locking control 2 to utilize the elastic deformation characteristics of the elastic deformation portion 10' to change the inner diameter of the clamping channel 100, reducing the parts of the tool holding mechanism and simplifying the structure.
[0092] The elastic deformation portion 10' can also be formed by reducing the thickness of the side wall of the clamping seat 1, so that the elastic deformation of this part is larger than that of the adjacent parts.
[0093] Certainly, in other embodiments, a vertical notch groove 100' is constructed on the inner side of the clamping seat 1, and the wall of the notch groove 100 is configured as at least a part of the elastic deformation portion 10'. The cross-section of the notch groove 100 is preferably U-shaped.
[0094] On the other hand, a flexible interlayer 104 is disposed within the clip holder 1, and the interior of the flexible interlayer 104 constitutes the clamping channel 100. The material selection of the flexible interlayer 104 can be known from other embodiments. For example, materials such as silica gel, rubber, and resin that can increase the clamping friction can be used.
[0095] Specifically, the clip holder 1 is made of a plastic material, and the flexible interlayer 104 is formed within the clip holder 1 by secondary injection molding. Of course, it can also be made separately and then assembled. The specific manufacturing method is the same as or similar to other embodiments of the present application.
[0096] Figures 14 to 16 As shown, in one solution of the coupling portion 10a, the clip holder 1 is provided with a vertical coupling groove 10, and the flexible interlayer 104 is provided with a filling portion 1043 that fills the coupling groove 10. The coupling groove 10 and the filling portion 1043 filled in the flexible interlayer 104 constitute the coupling portion 10a. The filling portion 1043 is a flexible material and does not affect the position change of the first side 101'.
[0097] In other embodiments, the flexible interlayer 104 covers the inner side of the coupling groove 10 without extending into the interior of the coupling groove 10.
[0098] Reference Figures 14 to 16 , in another solution of the coupling portion 10a, the clip holder 1 is provided with a vertical coupling groove 10, and the coupling groove 10 is coated or filled with a flexible material (not shown). The flexible material and the coupling groove 10 constitute the coupling portion 10a. It can be understood that the flexible material of this solution can be fixed in the coupling groove 10 by injection molding, bonding, etc.
[0099] Another solution of the coupling portion 10a (not shown) is that the coupling portion 10a is an elastically deformable structure formed by a reduced thickness structure of the side wall of the clip holder 1. As in other embodiments of the present application, the construction method of the elastic deformation portion 10'. Of course, the thinner the thickness of the coupling portion 10a, the better.
[0100] See Figure 17 As shown in the electronic cutting machine, the guiding installation channels 501 and 502 of the cutting member a are respectively movably installed to the working area 700 through the first guide rod 701 and the second guide rod 702. The belt installation channel 503 of the cutting member a is in transmission connection with a driving mechanism (not shown) inside the main body 7 through a transmission belt 705. The driving mechanism drives the cutting member a to reciprocate along the first guide rod 701 and the second guide rod 702 through the transmission belt 705. The driving mechanism (not shown) is not an improvement content of the present application and will not be specifically described. Door structures for opening or closing the working area 700 are respectively provided on the front side and the upper side of the main body 7. A cover a' can also be disposed outside the cutting member a to protect the cutting member a.
