Description

Technical Field

[0001] The invention relates to the technical field of parts cutting, and in particular to a processing and cutting device suitable for parts of printing equipment. Background Art

[0002] The core components of printing equipment include printing rollers, printed circuit boards, inking units, etc. In order to ensure printing quality, the processing quality of its core components is particularly important. Taking the processing technology of printing rollers as an example, it is specifically based on the grinding method in the cutting process. Please refer to the relevant content in the publication number CN112405146A.

[0003] Specifically for the printing roller, first of all, its size / volume is large and the grinding accuracy requirement is high. If the centerless grinding method is adopted, the grinding parameters of the workpiece to be processed are controlled by only two grinding wheels. However, due to the continuous contact and cutting between the grinding wheels in the overall grinding process, the workpiece to be processed will vibrate significantly, and the vibration will directly affect the grinding process. If the "forced fixation" method is adopted, the vibration amplitude of the workpiece to be processed will be interfered by the connecting rod / fixing structure. On the one hand, it will interfere with the overall grinding process and cause deviations in the processing accuracy of the printing roller surface. On the other hand, because the mass of the workpiece to be processed is large, the impact of the vibration under the large mass state is "magnified", such as directly increasing the workload of the connecting rod / fixing structure, and even causing the connecting rod / fixing structure to break. This application proposes a solution. Summary of the invention

[0004] The purpose of the present invention is to provide a processing and cutting device suitable for printing equipment parts, especially for the cutting process of the printing roller, one of the core components of the printing equipment. Firstly, because the workpiece is large in size and requires high grinding accuracy, in actual processing, the fixing method of the workpiece to be processed will affect the processed workpiece and increase the workload of the workpiece to be processed. If the centerless grinding method is adopted, the vibration generated by it will directly affect the grinding process.

[0007] A ventilation hose is arranged between the first pneumatic component and the second pneumatic component, the mounting platform is on the machine body assembly, and a supporting cylinder is installed on the mounting platform. The top end position of the supporting cylinder output shaft is fixedly connected to the bottom support platform, and the roller to be processed is arranged in the middle position between the assembly frame and the bottom support platform.

[0008] It is further configured as follows: four supporting feet are installed on one side of the corner portion, a roller is rotatably installed on each of the supporting feet, and the roller is inclined along the length direction of the roller to be processed.

[0009] It is further configured as follows: the assembly frame and the bottom support are arranged in a direction from top to bottom, and the assembly frame performs linear movement in a vertical direction through a vertical driving structure, and the first pneumatic component is installed on the assembly frame.

[0010] It is further configured as follows: a connecting rod arranged along the length direction of the roller to be processed is rotatably installed in the internal position of the corner portion, and a coil spring and a driving gear are respectively installed on the connecting rod along the direction from the corner portion to the sliding portion, one end of the coil spring is installed in the internal position of the corner portion, and one end of the connecting rod is rotatably installed on the center point of the outer wall of one end of the sliding portion.

[0011] It is further configured as follows: a straight gear plate meshed with a driving gear is slidably mounted in a vertical direction inside the auxiliary table, and the straight gear plate is symmetrically arranged along a direction perpendicular to the length of the roller to be processed.

[0012] It is further configured as follows: the upper arc plate and the lower arc plate are arranged in a direction from top to bottom, the lower end position of one of the straight gear plates is fixedly connected to the upper arc plate, and the lower curved surfaces of the upper arc plate and the lower arc plate match the outer curved surface of the roller to be processed.

However, the roller and the lower arc plate will not directly interfere with the grinding process of the processing roller by the main / auxiliary grinding wheel assembly. The purpose is to maintain the grinding position of the processing roller relative to the main / auxiliary grinding wheel assembly to ensure the preset processing requirements of the processing roller;

[0017] 2. Based on the above content, the roller to be processed is hydraulically supported by a supporting cylinder, but the key content is: limiting the setting direction of the lower arc plate and the roller relative to the roller to be processed, wherein the roller cooperates with the corner part for directional deflection, and the sliding part slides slightly in the vertical direction relative to the processing process of the roller to be processed, and according to the angular deflection process of the corner part relative to the sliding part, "actively causes" the air pressure change in the two pneumatic components, and by actively balancing the air pressure change in the two pneumatic components, the roller adapts to the rotational deflection angle and the inclination angle along the lateral direction of the roller to be processed. The key purpose is to maintain the relative position of the roller to be processed relative to the main / auxiliary grinding wheel assembly, to maintain the processing accuracy during the grinding process, to avoid the influence of vibration on the processing accuracy, and to not interfere with the overall centerless grinding process.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: For the cutting process of the printing cylinder, one of the core components of the printing equipment, firstly, because the workpiece is large in size and the grinding accuracy requirement is high, but in actual processing, the fixing method of the workpiece to be processed will affect the processed workpiece and increase the workload of the workpiece to be processed. If the centerless grinding method is adopted, the vibration generated by it will directly affect the grinding process. The following technical solutions are proposed:

[0029] Reference Figures 1 to 7The processing and cutting device adapted for printing equipment parts in this embodiment includes a body assembly 1, an auxiliary grinding wheel assembly 2, a main grinding wheel assembly 3, a mounting table 6 and a vertical driving structure 4. The auxiliary grinding wheel assembly 2 and the main grinding wheel assembly 3 are arranged on the body assembly 1 in a facing manner, and a roller to be processed is arranged between the auxiliary grinding wheel assembly 2 and the main grinding wheel assembly 3;

[0030] The machine body assembly 1 is provided with a roller assembly corresponding to the roller to be processed, and the roller assembly includes a bottom support platform 5, a mounting platform 6, an assembly frame 9, a first pneumatic assembly 10 and a second pneumatic assembly 13. The assembly frame 9 is symmetrically provided with lateral transverse plate assemblies 8 along the length direction of the roller to be processed on both sides thereof. The lateral transverse plate assembly 8 is provided with a corner portion 801 and a sliding portion 802. The corner portion 801 and the sliding portion 802 are rotatably connected. The sliding portion 802 is slidably connected in the vertical direction in the assembly frame 9 through the first pneumatic assembly 10. An auxiliary platform 11 is installed on the corner portion 801. An upper arc plate 12 and a lower arc plate 18 corresponding to the auxiliary platform 11 are provided at the lower side of the assembly frame 9.

[0031] A ventilation hose is arranged between the first pneumatic component 10 and the second pneumatic component 13, the mounting platform 6 is on the machine body assembly 1, and a supporting cylinder 7 is installed on the mounting platform 6, the top end position of the output shaft of the supporting cylinder 7 is fixedly connected to the bottom support platform 5, the roller to be processed is arranged in the middle position between the assembly frame 9 and the bottom support platform 5, four supporting feet are installed on one side of the corner part 801, and a roller is rotatably installed on each supporting foot, and the roller is inclined along the length direction of the roller to be processed.

[0032] Basic principle: This invention mainly focuses on the cutting process of the printing roller, one of the core components of the printing equipment, based on the centerless grinding process. Figure 1 and Figure 2 The roller to be processed is placed in the middle of the auxiliary grinding wheel assembly 2 and the main grinding wheel assembly 3. The grinding wheel structures in the auxiliary grinding wheel assembly 2 and the main grinding wheel assembly 3 are rotated in a directional manner, so that the curved surface of the roller to be processed can be synchronously ground, and the roller to be processed can be synchronously driven to move in a directional manner. This part is not described in detail in the present invention.

[0033] It should be noted that: in the conventional centerless grinding process, only the distance between the auxiliary grinding wheel assembly 2 and the main grinding wheel assembly 3 is required to match the grinding process parameters. There is no fixed clamping structure for the roller to be processed. Therefore, in the present invention, a limiting structure for the roller to be processed is mainly set. First, the bottom support 5 is driven to move up to a specific position by the supporting cylinder 7, and the assembly frame 9 is driven downward by the vertical driving structure 4. The purpose is to initially maintain the processing position of the roller to be processed relative to the auxiliary grinding wheel assembly 2 and the main grinding wheel assembly 3, thereby completing the limiting process of the roller to be processed.

[0034] Embodiment 2: Based on the technical content in Embodiment 1, a supplementary description is given to the limiting process of the roller to be processed:

[0035] The assembly frame 9 and the bottom support platform 5 are arranged in a direction from top to bottom, and the assembly frame 9 performs linear movement in the vertical direction through the vertical driving structure 4. The first pneumatic component 10 is installed on the assembly frame 9. A connecting rod 16 arranged along the length direction of the roller to be processed is rotatably installed in the inner position of the corner portion 801. The connecting rod 16 is respectively installed with a coil spring 17 and a driving gear 15 in the direction from the corner portion 801 to the sliding portion 802. One end of the coil spring 17 is installed in the inner position of the corner portion 801, and one end of the connecting rod 16 is rotatably installed at the center point of the outer wall of one end of the sliding portion 802. A straight gear plate 14 meshing with the driving gear 15 is slidably installed in the vertical direction at the inner position of the auxiliary table 11. The wheel plate 14 is symmetrically arranged along the length direction of the roller to be processed, the upper arc plate 12 and the lower arc plate 18 are arranged in the direction from top to bottom, the lower end position of one of the straight gear plates 14 is fixedly connected to the upper arc plate 12, the lower curved surfaces of the upper arc plate 12 and the lower arc plate 18 match the outer curved surface of the roller to be processed, the second pneumatic component 13 is installed on the upper arc plate 12, and the end position of the output shaft of the second pneumatic component 13 is arranged on the upper curved surface position of the lower arc plate 18, the end of the output shaft of the second pneumatic component 13 is arranged as a sphere, and the output shaft of the second pneumatic component 13 is movably connected to the lower arc plate 18, and the center point position of the output shaft of the second pneumatic component 13 is on the same horizontal axis as the center points of the upper and lower arc plates 18.

[0036] Because the roller to be processed is placed in the middle of the auxiliary grinding wheel assembly 2 and the main grinding wheel assembly 3, the vibration generated during the grinding process will directly affect the overall processing accuracy. Therefore, it is necessary to supplement and improve the limiting method proposed in the first embodiment, as shown below:

[0037] S1: The rollers connected to each support leg rotate in the same direction as the roller to be processed, but cannot directly interfere with the linear movement of the roller to be processed. Therefore, it is necessary to ensure that each roller is tilted at a small angle along the linear movement direction of the roller to be processed;

[0038] S2: As shown in the first embodiment, the roller to be processed will vibrate in an undirected manner during the overall grinding process, or there are differences in the grinding process of the roller to be processed by the auxiliary grinding wheel assembly 2 and the main grinding wheel assembly 3, which will affect the rotation mode of the roller. For this, the corner portion 801 and the sliding portion 802 in the lateral cross plate assembly 8 are rotationally connected, and it is necessary to ensure that the position of the rotation point between the corner portion 801 and the sliding portion 802 is in the same vertical plane as the direction of the center point of the roller to be processed, so that when there are differences in the grinding process of the roller to be processed, the overall corner portion 801 will deflect at an angle;

[0039] And if Figure 5As shown, the lateral transverse plate assembly 8 needs to be symmetrically arranged along the length direction of the roller to be processed, and its purpose is to adapt to the lateral angle deflection that may occur during the grinding process of the roller to be processed. For this purpose, it is necessary to ensure that the sliding portion 802 in the lateral transverse plate assembly 8 is restricted by the roller to be processed to slide in the vertical direction. This section is mainly used to introduce the adaptive activity process of the lateral transverse plate assembly 8 relative to the roller to be processed;

[0040] S3: In combination with S1 and S2, in the grinding process, firstly, the initial position of the roller to be processed needs to be limited by the supporting oil cylinder 7 and the vertical driving structure 4. In this process, the roller and the lower arc plate 18 will contact the surface of the roller to be processed, and the first pneumatic component 10 needs to be further used to adjust the setting position of the roller and the lower arc plate 18. Therefore, it can be understood that: firstly, the first pneumatic component 10 needs to be supplemented with air and pressurized to ensure that the roller contacts the roller to be processed first, and secondly, the second pneumatic component 13 needs to be supplemented with air and pressurized to ensure that the lower arc plate 18 contacts the roller to be processed. In order to ensure that the angular rotation of the auxiliary table 11 in the corner portion 801 is not interfered, a notch corresponding to the auxiliary table 11 is provided on the assembly frame 9;

[0041] S4: Combined with the contents of S1 to S3, when the overall lateral transverse plate assembly 8 undergoes a lateral angular deflection due to the vibration of the roller to be processed, the lateral transverse plate assembly 8 at the left or right position slides slightly in the vertical direction in the assembly frame 9. Similarly, the corner portion 801 will also undergo an angular deflection due to the vibration of the roller to be processed and the sliding portion 802. In this process, the angular deflection action of the corner portion 801 first drives the coil spring 17 to rotate and is compressed and deformed. In this process, under the action of the elastic potential energy of the coil spring 17, it will also drive the connecting rod 16 to rotate slightly and drive the driving gear 15 to rotate, and drive one of the straight gear plates 14 to move downward through the meshing relationship, refer to Figure 7, the upper guard plate 12 is driven to continue to move downward by the straight gear plate 14 in this position, which can drive the lower arc plate 18 to further contact the roller to be processed, but the lower arc plate 18 is difficult to move due to the resistance of the roller to be processed, thereby causing the second pneumatic component 13 to be compressed and contracted. For this, reference can be made to the conventional pneumatic rod structure. The first pneumatic component 10 and the second pneumatic component 13 are essentially pneumatic rods. Therefore, it is explained that: when the second pneumatic component 13 is compressed and contracted, the internal gas is compressed, and because a ventilation hose is provided between the first pneumatic component 10 and the second pneumatic component 13, the second pneumatic component 13 is compressed and contracted. The compressed gas in the pneumatic component 13 is transferred to the first pneumatic component 10, so that the first pneumatic component 10 further provides downward pressure on the sliding portion 802 in the lateral cross plate assembly 8, so that the roller further contacts the roller to be processed. It can be understood that: although the roller to be processed is limited by the roller and the lower arc plate 18, the overall limiting process is active, and specifically needs to be coordinated with the processing process of the roller to be processed to perform small and adaptive activities, that is, to maintain the processing position of the roller to be processed, and avoid excessive interference with the grinding process of the roller to be processed, thereby achieving the purpose of ensuring the processing accuracy.

[0042] In summary: the cutting process of the printing roller, one of the core components of the printing equipment, is based on the centerless grinding process, but the difference is that: it is not to limit the processing roller in a directly fixed manner, but to limit the processing roller in a movable manner based on the lower arc plate and the bottom support table. It is specifically aimed at the vibration generated by the roller to be processed during the grinding process, and the position change of the roller to be processed during the processing "actively causes" the air pressure change in the two pneumatic components. By actively balancing the air pressure changes in the two pneumatic components, the roller adapts to the rotation angle of the roller to be processed and the inclination angle along the lateral direction. The key purpose is to maintain the relative position of the roller to be processed with respect to the main / auxiliary grinding wheel assembly, to maintain the processing accuracy during the grinding process, to avoid the influence of vibration on the processing accuracy, and will not interfere with the overall centerless grinding process.
