DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of the utility model.

[0022] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0023] Please refer to Figure 1 A kind of cutter structure for cutting edge of aluminum plate for precision cutting, the core component of the present technical device is consistent with prior art device, and it is processing table 1.In actual application, processing table 1 is usually composed of complete table top, support leg, support roller and the like structure.For the convenience of demonstration, the present device only retains the table top structure, to facilitate determining the relative position of the parts of the device.

[0024] In prior art device, the upper end of processing table 1 is fixedly connected with a support seat, and the upper end of the support seat is provided with a conical groove.A front and rear axial cutting wheel 2 is arranged at the upper end of the conical groove, and the cutting wheel 2 is embedded in the conical groove.Through the meshing action between the conical groove and the cutting wheel 2, the edge of the aluminum plate is rolled, so that the technical effect of completing edge cutting by using the cutting wheel 2 is achieved.

[0025] Referring to Figure 1 , Figure 2 , Figure 3 It is shown that, compared with the prior art device, the present device is specially provided with a fixing frame 4, which is in fixed connection with the processing table 1.

[0026] The fixing frame 4 is provided with a through slot, which is specially designed to accommodate the cutting wheel 2, so that the cutting wheel 2 can be placed on the inner side of the fixing frame 4.

[0027] To ensure that the cutting wheel 2 has the ability of spontaneous rotation according to the actual processing requirements, the present device is designed with a follow-up shaft 7 coaxially fixedly connected with the cutting wheel 2.In the case that the cutting wheel 2 needs to rotate spontaneously, the effective control of the cutting wheel 2 can be realized through the cooperation of the corresponding driving equipment and the follow-up shaft 7.

[0028] It should be particularly pointed out that whether the cutting wheel 2 needs to rotate spontaneously or not, it should be kept in close proximity to the support seat.Combined with the supporting effect of the support seat on the workpiece to be processed, the normal operation of the cutting wheel 2 can be ensured.Therefore, if an error occurs during the processing, the cutting process can be quickly stopped by adjusting the distance between the cutting wheel 2 and the support seat, so as to ensure the accuracy of cutting.

[0029] Therefore, the device is provided with a rotatingly connected positioning frame 3 outside the follow-up shaft 7, and the upper end of the positioning frame 3 is fixedly connected with a positioning rod. The upper end of the fixed frame 4 is provided with a positioning hole, and the positioning rod can be inserted into the positioning hole. Through the cooperation of the positioning hole and the positioning rod, the sliding connection between the cutting wheel 2 and the fixed frame 4 is realized to control the distance between the cutting wheel 2 and the support seat.

[0030] It should be pointed out that in actual operation, if the workpiece to be processed is between the cutting wheel 2 and the support seat, it will cause a position conflict between the workpiece to be processed and the cutting wheel 2 and the support seat, and then a significant upward pushing force will be exerted on the cutting wheel 2. In order to ensure that the cutting wheel 2 and the support seat maintain a proper distance during cutting and prevent the cutting wheel 2 from being unable to complete the cutting task due to upward movement, the device is designed to constrain the upper end of the positioning rod, so that it protrudes from the fixed frame 4, and the part of the upper end of the positioning rod protruding from the fixed frame 4 is connected with the limiting mechanism to realize the movable connection.

[0031] Specifically, the limiting mechanism is composed of an upper and lower axial limiting shaft 14, which is firmly connected with the upper end surface of the fixed frame 4. The limiting shaft 14 is provided with an upper-end-opened sliding groove 15, and the limiting shaft 14 is also provided with a limiting groove 16 communicating with the sliding groove 15.

[0032] In addition, the inside of the limiting shaft 14 is configured with a cooperating ring 12 rotatably connected with the positioning rod, and the outside of the limiting shaft 14 is sleeved with a driving ring 11. Under this configuration, through the connecting shaft 17 fixedly connected between the cooperating ring 12 and the driving ring 11, the diameter of the connecting shaft 17 is equal to the width of the sliding groove 15 and smaller than the width of the limiting groove 16. Such a design enables the connecting shaft 17 to move linearly up and down inside the sliding groove 15, and to rotate around its own central axis without moving up and down inside the limiting groove 16. Therefore, the device can change the position of the connecting shaft 17 by rotating the cooperating ring 12, thereby realizing precise control of the height of the cutting wheel 2.

[0033] It must be pointed out that in actual operation, the device is in an initial state, and the cooperating ring 12 is moved downward, so that the connecting shaft 17 is at the same horizontal plane as the limiting shaft 14. At this time, by rotating the cooperating ring 12, the height of the positioning rod, i.e. the height of the cutting wheel 2, can be fixed, which ensures that the cutting wheel 2 and the support seat maintain a small distance and ensures the smooth progress of the cutting operation. In actual application, if the aluminum plate deviates from the predetermined path and causes cutting failure, the device can rotate the cooperating ring 12 so that the connecting shaft 17 is at the same vertical plane as the sliding groove 15. At this time, the upward pushing force exerted by the workpiece to be processed on the cutting wheel 2 will cause the cutting wheel 2 to move upward, and the connecting shaft 17 will be located inside the sliding groove 15.

[0034] Further, in order to ensure that the cutting wheel 2 can respond quickly and prevent the cutting wheel 2 from contacting the aluminum plate when the cutting wheel 2 rotates spontaneously, the device is provided with a tension spring II 8 at the upper end of the positioning frame 3, the two ends of the tension spring II 8 are respectively connected with the inner wall of the fixed frame 4 and the positioning frame 3, thereby providing an upward driving force for the positioning frame 3.

[0035] Specifically, in order to realize the control of the rotation of the driving ring 11, the device is provided with a follow-up plate 5 fixedly connected with the driving ring 11 on one side.

[0036] For details, please refer to Figure 1 and Figure 5 In order to ensure effective monitoring of the aluminum plate processing process and ensure that the device can detect the deviation of the aluminum plate during movement in time, the device is provided with a contact plate 10 on the left and right sides of the cutting wheel 2. In addition, the two contact plates 10 are fixedly connected through a common mounting frame 9.

[0037] On the basis of this configuration, a tension spring I 13 is arranged on the left and right sides of the mounting frame 9, and the two ends of the tension spring I 13 are respectively rotatably connected with the processing table 1 and the mounting frame 9. Through the action of the tension spring I 13, it is ensured that the contact plate 10 always maintains contact with the side edge of the aluminum plate. Each contact plate 10 has a tendency to move towards the aluminum plate. When the cutting of the aluminum plate is wrong, the distance difference between the two contact plates 10 will increase significantly. By measuring the distance difference between the two contact plates 10, the monitoring of the aluminum plate processing process can be realized.

[0038] In order to ensure that the device can automatically terminate the cutting process to reduce losses when cutting errors occur, the device is specially designed with a support rod 20 arranged between the two tension springs. The support rod 20 is rotatably connected with the processing table 1 and is connected with the mounting frame 9 through a key. Under this structure, when the distance deviation between the two contact plates 10 causes the mounting frame 9 to deflect, by limiting the transmission connection between the support rod 20 and the follow-up plate 5, the movement of the support rod 20 can be used to drive the cooperating ring 12 to rotate, thereby realizing the technical effect of separating the cutting wheel 2 from the support seat.

[0039] Further, the support rod 20 and the follow-up plate 5 are transmissionally connected through a pull rope 6.

[0040] Further, one side of the follow-up plate 5 is provided with a rope wheel, and the pull rope 6 is wound outside the rope wheel. The outer side of the rope wheel is wound with two pull ropes 6 in opposite helical directions. One end of the pull rope 6 is fixedly connected with the follow-up plate 5, and the other end is fixedly connected with the rope wheel. Therefore, no matter which direction the rope wheel rotates, there will always be a pull rope 6 that increases the number of turns wound on the rope wheel, providing a rotating power for the follow-up plate 5.

[0041] Further, the upper end of the support rod 20 is connected with the driving gear 18 through a key connection device, the driving gear 18 is matched with the transmission gear set 19, and then transmission connection is realized with the rope wheel. In this way, the transmission gear set 19 can enlarge the proportional relationship between the rotation range of the support rod 20 and the rope wheel, and ensure the accuracy of the device. When a small distance difference appears between the two contact plates 10, the cooperation ring 12 can be controlled to rotate, so that the cutting process is timely stopped.

[0042] In the practical application process of the utility model:

[0043] Firstly, the operator needs to press the positioning rod downward to ensure that the cooperation ring 12 is tightly matched with the upper end surface of the fixed frame 4. Then, the follow-up plate 5 is rotated, so that the connecting shaft 17 is accurately embedded into the limiting groove 16;

[0044] Then, the device will be started and normally operated. At this time, the cutting wheel 2 will be embedded into the tapered groove of the support seat to realize the cutting operation of the aluminum plate to be processed;

[0045] Then, with the continuous processing, if the aluminum plate to be processed is offset due to external force, a distance difference will be generated between the two contact plates 10. At this time, the support rod 20 will be synchronously rotated, the rope wheel will also be synchronously rotated, and then the follow-up plate 5 is correspondingly rotated;

[0046] Finally, with the rotation of the follow-up plate 5 driving the driving ring 11, the connecting shaft 17 will gradually be in the same vertical plane with the sliding groove 15. At this time, the elastic potential energy accumulated in the tension spring II 8 is released, so that the cutting wheel 2 is bounced upward.

[0047] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
