Figure 7 is another structural schematic diagram of the clamping member in the clamping device of the working component provided in an embodiment of the present application. Figure 8 is a structural schematic diagram of the bracket in the clamping device of the working component provided in an embodiment of the present application. The clamping device 10 of the working component may include a bracket 100 and a clamping member 200. The bracket 100 can support the working component, and the clamping member 200 can clamp the working component mounted on the bracket 100.

[0037] The bracket 100 may include a support portion 120 and a main body portion 140, and the support portion 120 and the main body portion 140 are fixedly connected. The support portion 120 is located on the outside of the main body portion 140, and the support portion 120 and the main body portion 140 are fixedly connected to each other to form a step structure. The support portion 120 may include a mounting hole 122 and a rotation groove 124, and the mounting hole 122 and the rotation groove 124 are connected to each other. The mounting hole 122 passes through the support portion 120 along one end of the support portion 120 toward the other end of the support portion 120, and the mounting hole 122 can be used to install operating components. The mounting hole 122 passing through the support portion 120 along one end of the support portion 120 toward the other end of the support portion 120 can be understood as: the mounting hole 122 passes through the support portion 120 along the top end of the support portion 122 toward the bottom end of the support portion 120.

[0038] The rotation groove 124 is provided on the side of the support portion 120, which can also be understood as the rotation groove 124 being provided on the outer surface of the support portion 120. The side of the support portion 120 connects one end of the support portion 120 and the other end of the support portion 120, and the rotation groove 124 is located at a corner of the support portion 120. The side of the support portion 120 connecting one end of the support portion 120 and the other end of the support portion 120 can be understood as: the side of the support portion 120 connects the top end of the support portion 120 and the bottom end of the support portion 120, or the side of the support portion 120 is the portion where the top end of the support portion 120 and the bottom end of the support portion 120 are connected to each other.

[0039] In an optional embodiment of the present application, the support portion 120 further includes an axial hole 126, which is in communication with the rotation slot 124. In the embodiment of the present application, there are two axial holes 126, and the two axial holes 126 are arranged opposite to each other.

[0040] In an optional embodiment of the present application, the support portion 120 further includes a fourth mounting slot 128 , which is in communication with the rotation slot 124 , and is adjacent to one of the two shaft holes 126 .

[0041] Among them, the operating component is, for example, one of a pen, a carving knife, and a letter cutting knife.

[0042] The clamping member 200 may include a rotating portion 220 and a clamping portion 240. The rotating portion 220 and the clamping portion 240 are fixedly connected, for example, integrally formed, and may be injection molded using a mold. The rotating portion 220 is disposed within the rotating groove 124 and is rotatable relative to the support portion 120 within the rotating groove 124, thereby switching the clamping member 200 between a clamping state and a non-clamping state.

[0043] When the clamping member 200 is in the clamping state, the end of the clamping portion 240 away from the rotating portion 220 is clamped to the support portion 120, and a portion of the rotating portion 220 is embedded in the mounting hole 122. As shown in Figures 3 and 4, the clamping portion 240 away from the rotating portion 220 is clamped to the support portion 120, which can be understood as an interference fit between the clamping portion 220 and the support portion 120. It should be noted that the fitting method between the clamping portion 220 and the support portion 120 is not limited to an interference fit; a snap fit can also be used, or a snap fit can be added to the interference fit between the clamping portion 220 and the support portion 120. The portion of the rotating portion 220 embedded in the mounting hole 122 can be understood as the portion of the rotating portion 220 in the mounting hole 122 being able to contact the working component installed in the mounting hole 122, and the portion of the rotating portion 220 embedded in the mounting hole 122 can directly press the working component installed in the mounting hole 122. Because the end of the clamping portion 240 away from the rotating portion 220 is clamped to the support portion 120, the clamping portion 240 and the rotating portion 220 jointly clamp the working component installed in the mounting hole 122, effectively clamping the working component installed in the mounting hole 122. Furthermore, by directly inserting the rotating portion 220 into the mounting hole 122 to squeeze the working component, and by combining the clamping portion 240 with the support portion 120 to achieve indirect clamping of the working component, the working component is clamped together by both direct and indirect methods. Compared to a method of clamping the working component alone, this embodiment of the present application can effectively reduce deformation of the clamping portion 240 and the rotating portion 220, thereby improving the clamping effect of the working component.

[0044] When the clamping member 200 is in a non-clamping state, the clamping portion 240 and the support portion 120 are disengaged, and the rotating portion 220 is located in the rotating groove 124. As shown in Figure 1, the disengagement of the clamping portion 240 and the support portion 120 can be understood as the clamping portion 240 and the support portion 120 are not matched, or in other words, not clamped. The rotating portion 220 is located in the rotating groove 124 can be understood as the rotating portion 220 is not embedded in the mounting hole 122, thereby facilitating the replacement of operating parts. In other optional embodiments of the present application, when the clamping member 200 is in a non-clamping state, the length of the rotating portion 240 located in the mounting hole 122 is less than the length of the rotating portion 240 located in the mounting hole 122 when the clamping member 200 is in the clamping state.

[0045] In an optional embodiment of the present application, when the clamping member 200 is in the clamping state, the rotating portion 220 is provided with a clamping structure 221 to enable the portion of the rotating portion 220 located within the mounting hole 122 to more effectively clamp the working component. When the clamping member 200 is in the clamping state, the end of the clamping portion 240 away from the rotating portion 220 is clamped to the support portion 120, and the clamping structure 221 is located within the mounting hole 122. When the clamping member 200 is in the unclamping state, the clamping portion 240 and the support portion 120 are disengaged, and the clamping structure 221 is located within the rotating groove 124. In other words, when the clamping member 200 is in the unclamping state, the length of the rotating portion 240 located within the mounting hole 122 is less than the length of the rotating portion 240 located within the mounting hole 122 when the clamping member 200 is in the clamping state.

[0046] In an optional embodiment of the present application, the clamping structure 221 may include a plurality of clamping strips protruding from the inner surface of the rotating portion 220 , and the plurality of clamping strips are arranged at intervals along one end of the support portion 120 toward the other end of the support portion 120 .

[0047] In an optional embodiment of the present application, the plurality of clamping bars are configured as an arc-shaped structure on a surface away from the rotating portion 220, and the plurality of clamping bars are configured to be concave toward the rotating portion 220. When the plurality of clamping bars of the present embodiment are pressed against the working component installed in the mounting hole 122, the contact area with the working component can be increased, thereby further improving the clamping effect on the working component installed in the mounting hole 122.

[0048] In an optional embodiment of the present application, the rotating portion 220 includes a curved surface 222 , and the curved surface 222 is concavely disposed toward the rotating portion 220 . The plurality of clamping bars are disposed on the curved surface 222 .

[0049] The rotating portion 220 can rotate relative to the support portion 120 in the rotating groove 124 via the rotating shaft. The clamping device 10 such as a working component further includes a rotating shaft 300 connecting the rotating portion 220 and the support portion 120. The rotating portion 220 can rotate relative to the support portion 120 around the rotating shaft 300.

[0050] The rotating portion 220 may be provided with an axial hole 223. The rotating portion 220 may further include a first mounting slot 224, a second mounting slot 225, and a third mounting slot 226. The first mounting slot 224 communicates with the axial hole 223, the second mounting slot 225 communicates with the axial hole 223, and the third mounting slot 226 communicates with the second mounting slot 225. In an optional embodiment of the present application, the rotating portion 220 may further include one or more weight-reducing slots 227 disposed on the end surface of the rotating portion 220, and one or more weight-reducing slots 228 disposed on the inner surface of the rotating portion 220. The weight-reducing slots 227 and 228 can reduce the weight of the rotating portion 220, thereby saving material.

[0051] A portion of the rotating shaft 300 can be disposed within the shaft hole 223, the first mounting groove 224, and the second mounting groove 225, while another portion of the rotating shaft 300 can be disposed within the two shaft holes 126. The ends of the rotating shaft 300 are respectively disposed within the two shaft holes 126. The rotating shaft 300 may include a first shaft body 320, a second shaft body 340, and a third shaft body 360. A portion of the first shaft body 320 is disposed within the shaft hole 223 and the second mounting groove 225, while another portion of the first shaft body 320 is disposed within one of the two shaft holes 126. The second shaft body 340 is disposed within the first mounting groove 224. The third shaft body 360 is disposed within the other of the two shaft holes 126. The third shaft body 360, the second shaft body 340, and the first shaft body 320 are fixedly connected, such as being integrally disposed. The second shaft body 340 is located between the first shaft body 320 and the third shaft body 360 . The diameter of the first shaft body 320 is smaller than that of the second shaft body 340 . The diameter of the second shaft body 340 is smaller than that of the third shaft body 360 .

[0052] In order to distinguish the shaft hole 126 from the shaft hole 223 , the shaft hole 223 may be defined as a first shaft hole, and the shaft hole 126 may be defined as a second shaft hole.

[0053] In an optional embodiment of the present application, the clamping device 10 of the working component further includes an elastic member 400, one end of the elastic member 400 is fixedly connected to the support portion 120, and the other end of the elastic member 400 is fixedly connected to the rotating portion 220. The elastic member 400 may include a first fixing portion 420, an elastic portion 460, and a second fixing portion 440. The first fixing portion 420, the elastic portion 460, and the second fixing portion 440 are connected in sequence. The first fixing portion 420 is fixedly connected to the support portion 120, the second fixing portion 440 is fixedly connected to the rotating portion 220, and the elastic portion 460 is sleeved on the rotating shaft 300.

[0055] 9 , which is a diagram illustrating a process of clamping a working component by a clamping device of the working component provided in an embodiment of the present application. First, S1 : prepare the working component and the clamping device of the working component, wherein the clamping device of the working component needs to be in a non-clamped state.

[0056] Then S2: align the working component and the mounting hole of the clamping device, and install the working component into the mounting hole.

[0057] Then S3: after the working component is installed in the installation hole, the clamping member of the clamping device is rotated along a predetermined direction, such as the X direction.

[0058] Finally, S4: the clamping member and the support portion of the bracket are matched, such as by interference fit, so as to clamp the working component in the mounting hole.

[0059] As shown in Figure 10, Figure 10 is a schematic diagram of a portion of the structure of the machining equipment provided in an embodiment of the present application. The machining equipment 1 includes a working component 20 and a clamping device 10, which is used to clamp and clamp the working component 20. The clamping device can be referred to above and will not be described in detail here.

[0060] As shown in Figure 11, Figure 11 is a schematic diagram of a portion of the structure of the mechanical processing equipment provided in an embodiment of the present application. The mechanical processing equipment 1 may further include a housing 30 and a cover plate 40. The housing 30 may include an opening 31 and a cavity 32, and the opening 31 and the cavity 32 are connected. The cover plate 40 and the housing 30 are rotatably connected, that is, the cover plate 40 can be rotated relative to the housing 30, so as to cover the opening 31 or open the opening 31. In particular, when the cover plate 40 covers the opening 31, the cover plate 40 closes the cavity 32.

[0061] 1 to 10 , the clamping device 10 is disposed within the cavity 32 of the housing 30, and the clamping member 200 of the clamping device 10 is disposed adjacent to the opening 31 of the housing 30. When the cover 40 rotates relative to the housing 30 to open the opening 31, the clamping member 200 of the clamping device 10 can be displayed through the opening 31, thereby facilitating an operator to operate the clamping member 200 through the opening 31, such as by operating the holding portion 240 of the clamping member 200, to switch the clamping member 200 between a clamped state and a non-clamped state.

[0062] When the clamping member 200 is in the fully opened state, or if the opening formed between the clamping member 200 and the bracket 100 is too large, the clamping member 200 may interfere with the housing 30 or the cover 40. This may at least increase the size of the housing 30, or even the size of the cover 40. For this reason, in order to reduce the size of the housing 30, or in other words, to reduce the space within the housing 30, in an optional embodiment of the present application, the elastic member 400 can limit the clamping member 200.

[0063] For example, the first fixing portion 420 is fixedly connected to the support portion 120, the second fixing portion 440 is fixedly connected to the rotating portion 220, and the elastic portion 460 is sleeved on the rotating shaft 300. Thus, the elastic member 400 can maintain the opening between the clamping member 200 and the bracket 100, such as the support portion 120, within a predetermined angle range. For example, FIG1 and FIG9 illustrate the position of the clamping member 200 relative to the bracket 100. Furthermore, the elastic member 400 ensures that when the clamping member 200 is in the open position, the opening of the clamping member 200 relative to the bracket 100 is not excessively large, thereby reducing or even eliminating interference between the clamping member 200 and the housing 30 and / or the cover 40. Therefore, when designing the housing 30 and the cover 40, compared to a solution in which the clamping member interferes with the housing, the embodiment of the present application can reduce the impact of the clamping member 200 on the size of the housing 30, thereby reducing the size of the housing 30 and even the size of the cover 40.

[0064] For example, the elastic member 400 can maintain the clamping member 200 within a preset angle range relative to the bracket 100, such as the opening between the support portion 120, such as the preset angle range of the opening is 30 degrees to 90 degrees. In an optional embodiment, the preset angle range of the opening is 45 degrees to 60 degrees.

[0065] It can be understood that the mechanical processing equipment defined in the embodiments of the present application can be understood as workpiece processing equipment.

[0066] The above is a detailed introduction to the clamping device and machining equipment of the working parts provided in the embodiments of the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for technical personnel in this field, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
