Description

TECHNICAL FIELD

[0001] The present application relates to the mechanical technical field, and particularly to a machining assembly, a machining device and a machining equipment. BACKGROUND

[0002] At present, an intelligent cutting machine usually provides pressure to a cutting knife through a motor or a spring to realize pushing power of the cutting knife, so that the cutting knife can cut or carve according to a preset cutting depth. Similarly, an intelligent drawing machine is the same. The motor pressing scheme is relatively complex and high in cost, and the spring pressing scheme is low in compatibility and cannot realize the conversion from cutting paper to cutting wood board within a certain stroke range. CONTENT OF THE UTILITY MODEL

[0003] To solve the above problems, the present application provides a machining assembly, which uses a magnetic part and an elastic part to realize large-range pressure adjustment within a short stroke range, improve the compatibility of the machining assembly, and reduce the cost of the machining assembly. In addition, the present application also provides a machining device and a machining equipment carrying the machining assembly, and the specific solutions are as follows.

[0004] In the first aspect, the present application provides a machining assembly for connecting a cutting knife or a pen holder. The machining assembly comprises:

[0005] a first base having an opening for connecting the cutting knife or the pen holder;

[0006] a first magnetic part fixed to the bottom of the first base and a second magnetic part opposite to the first magnetic part along a first direction and close to the opening of the first base for connecting the cutting knife or the pen holder;

[0007] an elastic part connected with the first base and extending along the first direction for connecting the cutting knife or the pen holder;

[0008] the cutting knife or the pen holder moves along the first direction to drive the second magnetic part and the elastic part to move along the first direction.

[0009] The first base is arranged to fix the first magnetic member and movably connect the cutting knife or the pen holder. The second magnetic member and the elastic member are arranged to be connected with the cutting knife or the pen holder. Since the second magnetic member and the elastic member are arranged in the first direction, when the cutting knife or the pen holder moves in the first direction, the length of the elastic member and the distance between the first magnetic member and the second magnetic member change. Thus, the elastic deformation force of the elastic member and the magnetic force of the first magnetic member and the second magnetic member can act on the cutting knife or the pen holder to provide working pressure for the cutting knife or the pen holder. Through the cooperation of the first magnetic member, the second magnetic member and the elastic member, the cutting knife or the pen holder is provided with a pushing force in the first direction, and the cutting knife or the pen holder can provide different sizes of pressure to the workpiece to be processed.

[0010] For example, when the cutting knife is needed to be used for cutting operation and a larger cutting force is needed, the cutting head of the cutting knife contacts the surface of the workpiece to be cut. Under the reaction force of the workpiece to be cut, the cutting knife can move away from the workpiece to be cut, i.e. move towards the first base, and compress the elastic member to a certain extent. At this time, the polarities of the first magnetic member and the second magnetic member can be set to be the same, so that the repulsive force generated by the first magnetic member and the second magnetic member pushes the cutting knife to move towards the workpiece to be cut, so as to increase the pressure of the cutting knife on the workpiece to be cut, thereby realizing the cutting effect.

[0011] When the cutting knife is needed to be used for cutting operation and a smaller cutting force is needed, the elastic member itself can be directly used to realize the force applying effect. When the cutting is not needed, the polarities of the first magnetic member and the second magnetic member can be set to be opposite, so that the attractive force generated by the first magnetic member and the second magnetic member can overcome the elastic recovery force of the elastic member, and make the cutting knife move towards the first base to move away from the workpiece to be cut.

[0012] The machining assembly provided by the application controls the machining assembly to apply pressure to the cutting knife or the pen holder through the cooperation of the elastic member, the first magnetic member and the second magnetic member, realizes a wide range of pressure adjustment in a short stroke range, improves the compatibility of the machining assembly, and the machining assembly has a simple structure and can reduce the cost of the machining assembly.

[0013] In an embodiment, the polarities of the first magnetic member and the second magnetic member are the same.

[0014] In the embodiment, the polarities of the first magnetic member and the second magnetic member are set to be the same, so that a repulsive force is formed between the first magnetic member and the second magnetic member, which makes the cutting knife or the pen holder move towards the workpiece to be processed or have a tendency to move towards the workpiece to be processed, and can increase the pushing force of the cutting knife or the pen holder.

[0015] In an embodiment, the two magnetic members are opposite in magnetism, and when the distance between the first magnetic member and the second magnetic member is less than or equal to a preset threshold, the first magnetic member and the second magnetic member are attracted to each other to reduce the thrust of the machining assembly.

[0016] In the embodiment, the polarity of the first magnetic member and the second magnetic member is opposite, so that an attractive force is formed between the first magnetic member and the second magnetic member. Thus, when the distance between the first magnetic member and the second magnetic member is less than or equal to a preset threshold, the attractive force can cause the cutting knife or the pen holder and the part connected to the first magnetic member to be close to each other or have a tendency to be close to each other, so as to reduce the thrust of the machining assembly. The preset threshold is a critical value, and the size of the preset threshold can be adjusted according to different actual needs. The preset threshold can be input manually or calculated automatically by a controller.

[0017] In an embodiment, at least one of the first magnetic member and the second magnetic member is an electromagnet.

[0018] In the embodiment, at least one of the first magnetic member and the second magnetic member is an electromagnet, so that by adjusting the polarity of the electromagnet, the relative distance between the first magnetic member and the second magnetic member can be diversified, and the machining assembly can be applied to different pressure application scenarios.

[0054] Please see Figure 1 , Figure 1 The structural schematic diagram of the processing equipment 300 provided in an embodiment of the present application is shown.

[0055] As Figure 1 shown, the processing equipment 300 provided by the present application comprises a processing platform 301, a guide 302, a manufacturing device 303 and a processing device 200. The processing platform 301 is used to carry a component to be processed. The guide 302 is fixed relative to the processing platform 301, the manufacturing device 303 is slidably connected to the guide 302, and the processing device 200 is installed on the manufacturing device 303. That is, the manufacturing device 303 can move relative to the processing platform 301 to drive the processing device 200 to move relative to the processing platform 301, so as to process the component to be processed carried on the processing platform 301. Exemplarily, the guide 302 is a guide rail, which extends in the vertical direction and is perpendicular to the surface of the processing platform 301.

[0056] The manufacturing device 303 is provided with a connecting portion, and the processing device 200 comprises a processing assembly 100 provided with a mounting portion (not shown in the figure), and the connecting portion corresponds to the mounting portion, so as to connect the processing assembly 100 on the manufacturing device 303. That is, the manufacturing device 303 and the processing assembly 100 are detachably connected. In another embodiment, the manufacturing device 303 and the processing assembly 100 can be integrally arranged.

[0057] Please refer to Figure 2 , wherein Figure 2 is a structural schematic diagram of the manufacturing device 303 provided in an embodiment of the present application.

[0058] As shown in Figure 2 , in an embodiment, the manufacturing device 303 comprises a 3D printing head, and the processing device 300 belongs to a 3D printing device. The 3D printing head is used to move relative to the processing platform 301 under the action of the guide 302 according to a preset printing path, and at the same time, extrude a molten printing consumable towards the processing platform 301, so as to print a three-dimensional object in a layer-by-layer manner. The processing device 200 can be used as an accessory part of the 3D printing head, and is used to process the part to be processed on the processing platform 301 along with the movement of the 3D printing head. Exemplarily, the working part of the processing device 200 comprises a cutting knife 201, that is, the processing device 200 can be used to cut the part to be processed carried on the processing platform 301.

[0059] It should be noted that in the above embodiment, the specific form of the manufacturing device 303 and the specific form of the working part of the processing device 200 are only used as an exemplary introduction, and do not represent the specific form of the manufacturing device 303 and the processing device 200 in other embodiments of the present application. For example, in another embodiment, the manufacturing device 303 can be arranged as a laser head provided with an output laser. At this time, the processing device 300 is arranged as a laser processing device 300, and the processing device 200 can also process the part to be processed on the processing platform 301 along with the movement of the laser head. The working part of the processing device 200 can also be arranged as a pen holder used to connect a pen. At this time, the processing device 200 can be used to draw the part to be processed carried on the processing platform 301.

[0060] For the convenience of introduction, the manufacturing device 303 is taken as a 3D printing head, and the working part of the processing device 200 is taken as a cutting knife 201 in the subsequent introduction of the present application.

[0061] Please refer to Figures 3 to 6 , wherein Figure 3 is a sectional structural schematic diagram of the processing assembly 100 provided in an embodiment of the present application. Figure 4 is a structural schematic diagram of the processing assembly 100 and the cutting knife 201 provided in an embodiment of the present application. Figure 5This is a schematic cross-sectional view of the processing component 100 and the cutting blade 201 provided in one embodiment of this application; Figure 6 This is an exploded view of the processing component 100 and the cutting blade 201 provided in one embodiment of this application.

[0062] like Figures 3 to 6 As shown, the processing assembly 100 provided in this application includes a first base 10, a first magnetic element 20, a second magnetic element 30, and an elastic element 40. The first base 10 has an opening and is used to connect a cutting blade 201. In one embodiment, the cutting blade 201 includes a connected main body 2011 and a working head 2012. The main body 2011 can be configured as the blade shank of the cutting blade 201, and the working head 2012 can be configured as the cutting tip of the cutting blade 201. The first base 10 is used to movably connect the main body 2011 of the cutting blade 201. The first magnetic element 20 is fixed to the bottom of the first base 10, meaning the first base 10 also serves to fix the first magnetic element 20. The first magnetic element 20 and the second magnetic element 30 are spaced apart along a first direction 001. The second magnetic element 30 is disposed opposite to the first magnetic element 20 along the first direction 001 and is located near the opening of the first base 10. The first direction 001 is the direction from which the bottom of the base moves away from or towards the opening, i.e., the vertical direction. The second magnetic element 30 is closer to the working platform than the first magnetic element 20. The second magnetic element 30 is used to connect to the cutting blade 201. This connection can be direct or indirect. The elastic element 40 is connected to the first base 10, i.e., fixed relative to it. The elastic element 40 extends along the first direction 001 and is used to connect to the cutting blade 201. This connection is generally indirect. The cutting blade 201 moves along the first direction 001, thereby causing the second magnetic element 30 and the elastic element 40 to move along the first direction 001.

[0063] The first base 10 is arranged to fix the first magnetic member 20 and movably connect the cutting knife 201. The second magnetic member 30 and the elastic member 40 are arranged to be connected with the cutting knife 201. Since the second magnetic member 30 and the elastic member 40 are arranged in the first direction 001, when the cutting knife 201 moves in the first direction 001, the length of the elastic member 40 and the distance between the first magnetic member 20 and the second magnetic member 30 change. Thus, the elastic deformation force of the elastic member 40 and the magnetic force of the first magnetic member 20 and the second magnetic member 30 can act on the cutting knife 201 to provide working pressure for the cutting knife 201. Through the cooperation of the first magnetic member 20, the second magnetic member 30 and the elastic member 40, the cutting knife 201 is provided with a pushing force in the first direction 001, and the cutting knife 201 can provide different sizes of pressure to the workpiece to be processed. Since the elastic coefficient of the elastic member 40 cannot be adjusted, if only the elastic member 40 is used to adjust the pressure of the cutting knife 201, the pushing force provided by the machining assembly 100 and the compression stroke distance of the elastic member 40 are approximately linearly related, and the machining assembly 100 cannot provide a larger change in the pushing force in a shorter compression stroke range. Therefore, the first magnetic member 20 and the second magnetic member 30 are arranged to cooperate with the elastic member 40, and the compression amount of the elastic member 40 and the magnetic force between the first magnetic member 20 and the second magnetic member 30 are controlled to control the relative position between the second magnetic member 30 and the first base 10, thereby controlling the pushing force provided by the machining assembly 100. Thus, the pushing force output by the machining assembly 100 can have a larger change in a shorter stroke range, thereby saving the compression stroke and reducing the length of the machining assembly 100 in the first direction 001, which is beneficial to realize the miniaturization of the machining assembly 100.

[0064] For example, when the cutting knife 201 needs to be used for cutting work and a larger cutting force is required, the working head of the cutting knife 201 contacts the surface of the workpiece to be cut, and under the reaction force of the workpiece to be cut, the cutting knife 201 can move away from the workpiece to be cut, i.e., move towards the first base 10, and compress the elastic member 40 to a certain extent. At this time, the first magnetic member 20 and the second magnetic member 30 can be arranged to have the same polarity, so that the repulsive force generated by the first magnetic member 20 and the second magnetic member 30 pushes the cutting knife 201 to move towards the workpiece to be cut, so as to increase the pressure of the cutting knife 201 on the workpiece to be cut, thereby realizing the cutting effect.

[0065] When the cutting operation needs to be performed by the cutting knife 201 and a small cutting force is required, the elastic member 40 itself can directly achieve the effect of force application through the deformation recovery force. When the cutting operation is not required, the polarity of the first magnetic member 20 and the second magnetic member 30 can be set to be opposite, so that the attractive force generated by the first magnetic member 20 and the second magnetic member 30 can overcome the deformation recovery force of the elastic member 40, and the cutting knife 201 can move towards the first base 10 to move away from the workpiece to be cut.

[0066] The machining assembly 100 provided in the application can control the pressure applied to the cutting knife 201 or the pen holder by the elastic member 40, the first magnetic member 20 and the second magnetic member 30, and a wide range of pressure adjustment can be achieved within a short stroke range, which improves the compatibility of the machining assembly 100. In addition, the machining assembly 100 has a simple structure and can reduce the cost of the machining assembly 100.

[0067] In an embodiment, the polarity of the first magnetic member 20 and the second magnetic member 30 is the same.

[0068] In the embodiment, the polarity of the first magnetic member 20 and the second magnetic member 30 is set to be the same, so that a repulsive force is formed between the first magnetic member 20 and the second magnetic member 30, which can make the cutting knife 201 or the pen holder move towards the workpiece to be machined or have a tendency to move towards the workpiece to be machined, and the thrust force of the cutting knife 201 or the pen holder can be increased.

[0069] In an embodiment, the polarity of the first magnetic member 20 and the second magnetic member 30 is opposite, and when the distance between the first magnetic member 20 and the second magnetic member 30 is less than or equal to a preset threshold value, the first magnetic member 20 and the second magnetic member 30 are attracted to reduce the thrust force of the machining assembly 100.

[0070] In the embodiment, the polarity of the first magnetic member 20 and the second magnetic member 30 is set to be opposite, so that an attractive force is formed between the first magnetic member 20 and the second magnetic member 30. When the distance between the first magnetic member 20 and the second magnetic member 30 is less than or equal to a preset threshold value, the attractive force can make the part of the cutting knife 201 or the pen holder connected to the first magnetic member 20 and the first base 10 close to each other or have a tendency to close to each other, so as to reduce the thrust force of the machining assembly 100. The preset threshold value is a critical value, and the size of the preset threshold value can be adjusted according to different actual needs. The preset threshold value can be input manually or calculated automatically by a controller.

[0071] In an embodiment, at least one of the first magnetic member 20 and the second magnetic member 30 is an electromagnet.

[0072] In the embodiment, at least one of the first magnetic member 20 and the second magnetic member 30 is an electromagnet, so that by adjusting the polarity of the electromagnet, the relative distance between the first magnetic member 20 and the second magnetic member 30 can be diversified, and the machining assembly 100 can be applied to different pressure application scenarios.

[0073] For example, the first magnetic member 20 fixed to the first base 10 is an electromagnet. By energizing or de-energizing the electromagnet, the polarity of the electromagnet can be changed, so as to adjust the magnetic force between the first magnetic member 20 and the second magnetic member 30. Further, by changing the current flowing into the electromagnet, the magnitude of the magnetic force between the first magnetic member 20 and the second magnetic member 30 can also be controlled, so as to further control the magnitude of the pressure provided to the component to be machined. That is, by adjusting the polarity and the magnitude of the magnetic force of the electromagnet, the relative distance between the first base 10 and the second magnetic member 30 can be diversified, and the machining assembly 100 can be applied to different scenarios.

[0074] It should be noted that the structure in which the first magnetic member 20 fixed to the first base 10 is an electromagnet in the above embodiment is only an exemplary introduction, and in another embodiment, the second magnetic member 30 can also be an electromagnet. By using two electromagnets, more diversified control of the relative distance between the second magnetic member 30 and the first base 10 can be achieved. In yet another embodiment, the first magnetic member 20 and the second magnetic member 30 can both be permanent magnets. At this time, the elastic member 40, the first magnetic member 20 and the second magnetic member 30 cooperate to provide pressure to the component to be machined.

[0075] In an embodiment, the number of elastic members 40 is two, and the two elastic members 40 are coaxially arranged, and the elastic coefficients of the two elastic members 40 are different. It can be understood that by arranging two coaxially arranged elastic members 40 and setting the elastic coefficients of the two elastic members 40 to be different, the machining assembly 100 can achieve more gradient adjustment of the pressure magnitude.

[0076] Further, the diameters of the two elastic members 40 are different. For ease of introduction, one of the elastic members 40 is defined as a first elastic member 40, and the other elastic member 40 is defined as a second elastic member 40, and the first elastic member 40 is arranged on the periphery of the second elastic member 40. That is, the diameter of the first elastic member 40 is smaller than the diameter of the second elastic member 40. The elastic coefficient of the first elastic member 40 is greater than the elastic coefficient of the second elastic member 40.

[0077] It should be noted that the number of elastic members 40 and the relationship between each elastic member 40 in the above embodiment is only an exemplary introduction, and in other embodiments, the number of elastic members 40 can be three, four, five, etc., each elastic member 40 can be different in diameter and / or length, different in material, etc., which is not particularly limited in the present application.

[0078] In an embodiment, the elastic member 40 is a compression spring.

[0079] In an embodiment, the machining assembly 100 further comprises a second base 50 opposite the first base 10 along the first direction 001, the second magnetic member 30 is arranged on the side of the second base 50 facing the first base 10, and the first magnetic member 20 is arranged on the side of the first base 10 facing the second base 50.

[0080] In an embodiment, the cutting knife 201 is detachably connected to the machining assembly 100.

[0081] In an embodiment, the first base 10 comprises a through hole 21 extending through itself along the first direction 001, and the cutting knife 201 or the pen holder comprises a main body portion 2011 and a working head 2012 connected together, the end of the main body portion 2011 away from the working head 2012 is arranged in the through hole 21 and is in sliding connection with the first base 10. The end of the main body portion 2011 close to the working head 2012 is in detachable fixed connection with the second base 50. Thus, when the main body portion 2011 slides relative to the first base 10 along the first direction 001, the second base 50 can be moved relative to the first base 10, thereby adjusting the distance between the first base 10 and the second base 50.

[0082] In the embodiment, by arranging the through hole 21 on the first base 10 and making the main body portion 2011 of the cutting knife 201 or the pen holder pass through the through hole 21 to be in sliding connection with the first base 10, and arranging the end of the main body portion 2011 close to the working head 2012 to be in detachable fixed connection with the second base 50, the cutting knife 201 or the pen holder can be nested in the first base 10 and the second base 50, thereby making the machining device 200 compact in structure, facilitating the miniaturization design of the machining device 200.

[0083] When the machining device 200 provided by the present application continues to move towards the component to be machined, the working head 2012 of the cutting knife 201 further compresses the elastic member 40 to a certain extent, the first magnetic member 20 and the second magnetic member 30 are close to each other, and the magnetic force between the first magnetic member 20 and the second magnetic member 30 starts to interact. The machining device 200 provided by the present application can control the relative position between the working head 2012 of the cutting knife 201 and the first base 10 by controlling the compression amount of the elastic member 40 and the magnetic force between the first magnetic member 20 and the second magnetic member 30, so as to control the cutting state of the working head 2012 and the size of the cutting force.

[0084] For example, in an embodiment, the polarities of the first magnetic member 20 and the second magnetic member 30 are the same, and the machining device 200 provided by the present application moves towards the object to be cut and makes the working head 2012 contact and abut against the object to be cut, and the elastic member 40 is continuously compressed to a first state, a second state and a third state. In the first state, the distance between the first magnetic member 20 and the second magnetic member 30 is relatively far, at this time the magnetic force between the first magnetic member 20 and the second magnetic member 30 does not work, the working head 2012 only provides pressure for cutting work through the restoring force of the deformation of the elastic member 40, at this time the working head 2012 can cut relatively thin objects to be cut such as paper. In the second state, the distance between the first magnetic member 20 and the second magnetic member 30 is relatively close, the repulsive force between the first magnetic member 20 and the second magnetic member 30 starts to act on the working head 2012 and the first base 10, so that the cutting knife 201 has a tendency to move the working head 2012 towards the object to be cut in the first direction 001, the working head 2012 realizes cutting work under the pressure provided by the cooperation of the elastic member 40, the first magnetic member 20 and the second magnetic member 30, at this time the working head 2012 can cut relatively thick objects to be cut. In the third state, the elastic member 40 reaches the compression limit, the distance between the first magnetic member 20 and the second magnetic member 30 is infinitely close, at this time the working head 2012 is mainly provided with pressure by the repulsive force between the first magnetic member 20 and the second magnetic member 30, at this time the working head 2012 can cut relatively thick objects to be cut such as wood boards.

[0085] In another embodiment, the processing device 200 provided by the present application is provided with a plurality of cutting knives 201, and the polarities of the first magnetic member 20 and the second magnetic member 30 in one of the cutting knives 201 are opposite. When the cutting knife 201 moves towards the object to be cut and the working head 2012 contacts and abuts against the object to be cut, the elastic member 40 is continuously compressed to continuously bring the first magnetic member 20 and the second magnetic member 30 closer to each other. When the distance between the first base 10 and the second base 50 is less than or equal to a preset threshold, the attractive force between the first magnetic member 20 and the second magnetic member 30 is greater than the deformation restoring force of the elastic member 40, and the working head 2012 is stably positioned at a position relatively close to the first base 10, so that the cutting knife 201 can be retracted to be in a non-cutting state, thereby avoiding interference of the cutting knife 201 with the cutting operation of the adjacent cutting knife 201.

[0086] It can be understood that, by the cooperation of the elastic member 40, the first magnetic member 20 and the second magnetic member 30, the positions of the first base 10 and the second base 50 are controlled, so that a wide range of pressure adjustment can be realized in a short stroke, the compatibility of the processing device 200 is improved, and the cutting state of the working head 2012 can be controlled. In addition, the structure is simple, and the cost is relatively low. The processing device 200 can smoothly transition from the approximately linear pressure range provided by the elastic member 40 to the nonlinear pressure range provided by the first magnetic member 20 and the second magnetic member 30, so as to ensure the cutting stability of the cutting knife 201 and improve the cutting effect of the cutting knife 201.

[0087] It should be noted that the nesting of the cutting knife 201 and the processing assembly 100 in the above-mentioned embodiments is only an exemplary introduction, and in other embodiments, the cutting knife 201 can be arranged outside the processing assembly 100 and directly or indirectly connected with the processing assembly 100, and the pushing force can also be provided to the cutting knife 201.
