Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plate processing, in particular to a plate double-face chamfering tool, device and method. BACKGROUND

[0002] In the field of plate processing, especially in the production and application process of metal plates, the processing quality of the plate edges directly affects the assembly accuracy, use safety and appearance quality of the products. Due to the functional requirements or auxiliary requirements of product design, the scenario of chamfering the edge part of the steel plate is increasing. For example, in the products such as mechanical equipment shell and precision instrument frame, in order to avoid the sharp edges causing harm to personnel, the edge of the steel plate needs to be rounded and chamfered; in the plate splicing assembly scenario, in order to ensure the tightness of welding or bolt connection, a bevel chamfer of a specific angle needs to be set according to the assembly gap requirement; and in part of high-precision part processing, even different depths of chamfering need to be realized on different sections of the same plate edge according to the complex design drawing. As can be seen, the chamfering of the edge of the steel plate has shown the characteristics of multi-specification and differentiation, and the requirements for chamfering size accuracy and angle consistency are also increasing.

[0003] However, at the present stage, there are still significant technical pain points in the double-face polishing and multi-specification chamfering processing of the plate edges, which are difficult to meet the efficiency, stability and flexibility requirements of industrial production. Firstly, the stability and consistency of double-face polishing processing are poor. The plate edge double-face polishing equipment commonly used in the industry at present mostly adopts the structural design of fixed polishing wheel set cooperating with linear conveying mechanism. On the one hand, due to the deviation of the flatness of the plate, vibration of the conveying mechanism or insufficient positioning accuracy in the conveying process, the contact pressure of the plate edge and the polishing wheel is uneven, which further causes local over-polishing or insufficient polishing, so that the double-face polishing effect of the same batch or even the same plate edge is different; on the other hand, the polishing wheel of the traditional polishing equipment is difficult to realize automatic compensation after wear, and frequent manual shutdown adjustment of the polishing wheel position or replacement of the polishing wheel is required, which not only reduces the production efficiency, but also further aggravates the instability of the polishing quality, making it difficult to ensure the consistency of mass plate processing.

[0004] Secondly, the existing processing equipment is difficult to adapt to different specifications of chamfering. The current processing equipment for chamfering the edge of the steel plate is mostly single-specification special equipment, i.e. a device can only realize chamfering of a fixed depth. When different specifications of chamfering need to be processed, complex parameter adjustment needs to be performed again, which not only consumes time and effort, but also easily causes chamfering precision not to meet the design requirements due to adjustment errors.

[0005] In summary, in the field of plate edge processing, how to develop an integrated processing technology that can simultaneously realize stable and consistent double-sided polishing processing and flexible adaptation to different specifications of chamfering processing has become a key problem to be solved in the current industry, and it is of great significance to improve plate processing quality, improve production efficiency and reduce production cost.

DETAILED DESCRIPTION

[0023] The present application will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present application and implement it, but the embodiments are not limiting to the present application.

[0024] Embodiment one:

[0025] Referring to Figure 1 and Figure 2As shown, the plate double-side chamfering tool in the embodiment comprises a mounting frame 100, a driver 200 arranged on the mounting frame 100, and a chamfering mechanism 300 comprising a cutting assembly 310 and a limiting assembly 320. The cutting assembly 310 comprises a rotary connecting shaft 311, a support seat 313, two cutting modules 314 and a guide wheel 315. One end of the rotary connecting shaft 311 is connected to a working end of the driver 200, and the other end extends along the length direction of the support seat 313 to penetrate through the support seat 313. An outer surface of the support seat 313 is provided with external threads. The two cutting modules 314 and the guide wheel 315 are both sleeved and connected to the extended end of the rotary connecting shaft 311, wherein the guide wheel 315 is located between the two cutting modules 314, and the two cutting modules 314 are symmetrically arranged to synchronously chamfer both sides of a plate to be machined 500. The limiting assembly 320 comprises a connecting sleeve 321 and a limiting plate 322. An inner surface of the connecting sleeve 321 is provided with internal threads 3211, which can be rotatably sleeved on the outer surface of the support seat 313. The limiting plate 322 is arranged on a side of the connecting sleeve 321 facing the cutting modules 314, and moves synchronously with the support seat 313 and can abut against the side wall of the plate to be machined 500 to adjust the relative position of the cutting modules 314 and the plate to be machined 500.

[0026] The plate double-side chamfering tool, device and method can directly adjust the relative position of the cutting modules 314 and the plate according to different chamfering groove depth requirements through the adjusting function of the limiting assembly 320 during the chamfering process, without the need to replace complex components, thereby covering various processing scenes from shallow grooves to deep grooves, greatly improving the adaptation ability of the device to different processing requirements, and being especially suitable for industrialized production scenes of multi-batch and multi-specification plate chamfering.

[0027] Meanwhile, the structure design can quickly complete the relative position calibration, significantly shorten the preparation period of specification switching, effectively improve the overall processing efficiency, avoid the error risk caused by manual debugging, and ensure the consistency of different batches of processing. Moreover, the limiting assembly 320 limits the relative position in real time, ensures that the cutting modules 314 always maintain the preset processing depth during the processing process, effectively avoids the depth deviation, improves the flatness and precision of the chamfering groove, reduces the subsequent polishing and other secondary processing procedures, and reduces the overall processing cost.

[0028] The plate double-side chamfering tool in the embodiment further comprises a floating force control mechanism 400 and a control mechanism, and the mounting frame 100 is connected to the floating force control mechanism 400. The floating force control mechanism 400 provides controllable floating power and displacement compensation capability for the entire driving and processing module. On the one hand, the floating force control mechanism 400 can drive the mounting frame 100 to drive the chamfering mechanism 300 to adjust the displacement in real time, so as to avoid processing defects caused by rigid contact. On the other hand, the floating force control mechanism 400 can ensure that the contact pressure between the cutting module 314 and the edge of the plate is always stable during the processing process by presetting a constant pressure, so as to avoid excessive cutting caused by excessive pressure and insufficient cutting caused by insufficient pressure, and to provide protection for uniform cutting of plates of different materials.

[0029] In the embodiment, the mounting frame 100 is a basic bearing component of the tool, which provides a stable mounting reference and support frame for the driver 200, the chamfering mechanism 300 and other structures. By fixing the relative positions of various components, it ensures that the power output by the driver 200 can be stably transmitted to the chamfering mechanism 300, and at the same time avoids cutting deviation caused by component shaking during processing. It is the basic premise to ensure the stability of the overall structure of the tool and the processing precision, and provides reliable structural support for the cooperative work of subsequent components.

[0030] Specifically, the mounting frame 100 in the embodiment comprises a floating connecting plate 110, a driving connecting frame 120 and a locking ring 130. One side of the floating connecting plate 110 is connected to the working end of the floating force control mechanism 400, and the other side is connected to the driving connecting frame 120. The driving connecting frame 120 is provided with a connecting groove matched with the shape of the driver 200. The locking ring 130 is detachably connected to the driving connecting frame 120 through a plurality of connecting pins 140, so as to lock the driver 200 in the connecting groove.

[0031] The floating connecting plate 110 can drive the whole driving connecting frame 120 and the connected driver 200 and the chamfering mechanism 300 to make a small floating adjustment through cooperation with the floating force control mechanism 400. The driving connecting frame 120 is provided with a connecting groove matched with the shape of the driver 200. Through the shape matching design, the positioning and installation of the driver 200 can be quickly realized, the coaxiality of the driver 200 with the rotating connecting shaft 311 after installation is ensured, the power transmission loss or eccentric rotation of the rotating connecting shaft 311 caused by installation deviation is avoided, and the stable power transmission is ensured. The locking ring 130 is detachably connected to the driving connecting frame 120 through a plurality of connecting pins 140. After the driver 200 is placed in the connecting groove, the driver 200 is firmly locked in the connecting groove through the fixing action of the locking ring 130, so as to prevent the position deviation of the driver 200 caused by vibration or stress during processing. Meanwhile, the detachable design facilitates the later maintenance and replacement of the driver 200, and the whole mounting frame 100 does not need to be disassembled, thereby reducing the operation difficulty of equipment operation and maintenance.

[0032] As shown in Figure 3 and Figure 4 , the driver 200 in the embodiment provides continuous and stable rotary polishing driving force for the rotation of the rotating connecting shaft 311. The specific type of the driver 200 is not limited in the present application. The chamfering mechanism 300 is used to chamfer the double sides of the plate to be processed 500. The cooperation of the internal cutting assembly 310 and the limiting assembly 320 realizes the functions of cutting processing and accurate positioning, respectively. The rotating connecting shaft 311 in the cutting assembly 310 receives the power transmitted by the driver 200 to stably rotate around the axis, and serves as the installation carrier of the cutting module 314 and the guide wheel 315, which can synchronously transmit power to the two cutting modules 314 to ensure that the rotation speeds of the two cutting modules 314 are consistent. The support seat 313 not only provides radial support for the rotating connecting shaft 311 to avoid radial deviation of the rotating connecting shaft 311 during high-speed rotation, but also forms cooperation with the internal thread 3211 of the connecting sleeve 321 through the external thread arranged on the outer surface of the support seat 313 to provide a transmission basis for the position adjustment of the limiting assembly 320, and limits the axial movement of the rotating connecting shaft 311 through the structural strength to ensure the stability of the cutting process. The two symmetrical cutting modules 314 are sleeved on the extended end of the rotating connecting shaft 311 and rotate at high speed under the driving of the rotating connecting shaft 311 to cut the edge of one side or both sides of the plate to be processed 500. The guide wheel 315 is located between the two cutting modules 314 and is in contact with the surface of the plate to be processed 500 during the processing process. On one hand, the guide wheel 315 plays a guiding role to guide the plate to move smoothly along the preset path and avoid the cutting position deviation caused by the deviation of the plate during the conveying process. On the other hand, the guide wheel 315 limits the relative distance between the plate and the cutting module 314 through the contact with the plate to further improve the accuracy of the processing position.

[0033] Further, the support seat 313 in the embodiment comprises a mounting portion 3131 and a threaded portion 3132 connected to each other, the mounting portion 3131 is connected to the rotary connecting shaft 311 through the bearing 312, and a grease nipple is arranged on the mounting portion 3131, and the external thread structure is arranged on the threaded portion 3132. Among them, the mounting portion 3131 is used to provide stable radial support for the rotary connecting shaft 311, which is connected with the rotary connecting shaft 311 through the bearing 312, which can not only reduce the friction resistance when the rotary connecting shaft 311 rotates at high speed, avoid the wear of the components caused by rigid contact, but also limit the radial movement of the rotary connecting shaft 311, ensure that it always rotates coaxially, and further ensure that the cutting module 314 and the guide wheel 315 arranged on the shaft end rotate stably, prevent the machining defects such as uneven chamfer depth and edge burr caused by shaft body offset. At the same time, the grease nipple arranged on the mounting portion 3131 provides a convenient channel for long-term lubrication of the bearing 312: the operator can inject lubricating grease into the inside of the bearing 312 through the grease nipple, continuously reduce the friction loss between the inner and outer rings and the rolling elements of the bearing 312, avoid the bearing 312 from generating high temperature, abnormal sound and even jamming due to dry friction, significantly prolong the service life of the bearing 312, reduce the frequency of tool downtime maintenance, and ensure the continuity of the machining process. The threaded portion 3132 and the internal thread 3211 of the connecting sleeve 321 in the limiting assembly 320 form a precise fit to form a threaded transmission pair. When it is necessary to adjust the relative position of the cutting module 314 and the plate to be machined 500 to adapt to different chamfer groove depth requirements, the connecting sleeve 321 can be driven to move smoothly along the axis direction of the threaded portion 3132 through the engagement transmission between threads, and then the limiting plate 322 is adjusted in position. Further, the characteristics of threaded transmission not only can realize precise control of position adjustment, but also can lock the position of the connecting sleeve 321 after adjustment by relying on the self-locking property of the thread, avoid the displacement of the connecting sleeve 321 due to vibration during machining, ensure the stable and reliable abutment and limiting of the limiting plate 322 to the plate, and provide guarantee for the precision consistency of different specifications of chamfer machining.

[0034] Further, the outer surface of the connecting sleeve 321 in the embodiment is provided with a scale 3212, and the cutting assembly 310 is also provided with a pointer 317, which is connected to the mounting portion 3131 and points to the scale 3212 to feedback the relative position of the cutting module 314 and the plate to be machined 500. The scale 3212 on the outer surface of the connecting sleeve 321 is marked with the displacement scale in the axial direction in numerical form, and each scale unit corresponds to the accurate change amount of the relative position of the cutting module 314 and the plate edge. Specifically, each grid in the embodiment represents a chamfer depth adjustment of 0.1 mm. The pointer 317 is fixedly connected to the mounting portion 3131 of the support seat 313, and the tip thereof always points to the scale 3212 area of the connecting sleeve 321 to form a dynamic indication reference. When the connecting sleeve 321 is rotated to adjust the position of the limiting component 320, the connecting sleeve 321 moves in the axial direction along the threaded portion 3132 of the support seat 313, and at this time, the relative position of the pointer 317 and the connecting sleeve 321 changes. The relative distance between the cutting module 314 and the plate to be machined 500 can be directly read through the numerical value of the scale 3212 pointed by the pointer 317, so that the visualization and quantitative control of position adjustment are realized.

[0035] Further, in the embodiment, the chamfer mechanism 300 further comprises an anti-disengagement piece 316 connected to the end portion of the rotating connecting shaft 311 and abutting against the cutting module 314. Specifically, the anti-disengagement piece 316 is an axial limiting structure of the cutting module 314 and the guide wheel 315 sleeved on the extended end of the shaft body. Since the cutting module 314 needs to rotate at high speed with the rotating connecting shaft 311 during machining and will generate a continuous cutting impact force with the edge of the plate to be machined 500, if only the sleeving cooperation of the shaft body and the module is relied on, the cutting module 314 will easily move in the axial direction of the rotating connecting shaft 311 or even fall off from the shaft end due to centrifugal force and impact force, which will cause equipment failure or safety hazards. After the anti-disengagement piece 316 is fixed to the shaft end by screw connection, clamping or other ways, it abuts against the outer side surface of the cutting module 314, which can provide the cutting module 314 with continuous and stable axial constraint force, completely eliminate the risk of axial movement or falling off of the module, and ensure the overall assembly stability of the cutting assembly 310.

[0036] Referring to Figure 5As shown, the cutting module 314 includes a tool holder 3141, a plurality of blades 3142, and a plurality of locking screws 3143, the tool holder 3141 is sleeved and connected to the rotating connecting shaft 311, and the plurality of blades 3142 are uniformly and spacedly connected to the tool holder 3141 through the plurality of locking screws 3143. Specifically, the tool holder 3141 serves as the mounting base of the blades 3142 and rotates synchronously with the rotating connecting shaft 311; the plurality of blades 3142 are uniformly and spacedly fixed on the tool holder 3141 through the locking screws 3143 to form a ring-shaped cutting structure, which can continuously and uniformly cut the edge of the plate; and the locking screws 3143 can firmly lock the position of the blades 3142 to prevent the blades 3142 from loosening or deviating due to vibration or stress during high-speed cutting, and facilitate the replacement and angle adjustment of the blades 3142 to adapt to the chamfering processing requirements of different specifications. The specific shape and number of the blades 3142 are not limited in the present application, and in the actual processing process, the cutting module 314 with different shapes or numbers of blades 3142 can be replaced according to the chamfering requirements of the test piece.

[0037] The connecting sleeve 321 in the limiting assembly 320 is threadedly connected with the outer thread of the support seat 313, can rotate around the outer surface of the support seat 313, and can drive the operator to move along the length direction of the support seat 313 by rotating the connecting sleeve 321, thereby synchronously driving the limiting plate 322 to move, thereby providing an operable adjusting structure for adjusting the relative position of the cutting module 314 and the plate. The adjusting mode of the thread cooperation has the characteristics of high adjusting precision and stable position locking, and avoids the position deviation caused by vibration after adjustment. The limiting plate 322 is arranged on the side of the connecting sleeve 321 facing the cutting module 314 and moves synchronously with the connecting sleeve 321. Before processing, the limiting plate 322 can be abutted against the side wall of the plate to be processed by adjusting, and the distance between the cutting module 314 and the plate edge is indirectly limited by the abutment limiting of the plate. When chamfering grooves with different depths need to be processed, the position of the limiting plate 322 can be adjusted by rotating the connecting sleeve 321, so that the depth of the cutting module 314 cutting into the plate can be changed without replacing the cutting module 314 or other complex components. At the same time, during the processing process, the limiting plate 322 continuously abuts against the side wall of the plate to form real-time limitation to the movement path of the plate, thereby avoiding the fluctuation of the cutting depth caused by vibration or conveying deviation of the plate, ensuring that the cutting module 314 always maintains the preset processing depth, thereby ensuring the flatness and precision of the chamfering groove and reducing the subsequent secondary processing requirements.

[0038] Referring to Figures 6 to 9As shown, the limiting plate 322 includes an assembly part 3221 and a stop part 3222, the internal thread structure is arranged on the inner wall of the assembly part 3221, the stop part 3222 is arranged on the side of the assembly part 3221 towards the cutting module 314, and the cross-sectional diameter of the stop part 3222 is greater than that of the assembly part 3221, so as to abut against the plate to be processed 500. Based on the above structure, the limiting plate 322 not only realizes stable connection with the connecting sleeve 321, but also accurately completes the abutting and limiting of the plate to be processed 500. Specifically, the internal thread structure arranged on the inner wall of the assembly part 3221 can be precisely engaged with the external thread of the connecting sleeve 321, so as to firmly fix the limiting plate 322 on the side of the connecting sleeve 321 towards the cutting module 314. This threaded connection mode not only ensures the synchronous movement of the limiting plate 322 and the connecting sleeve 321, but also avoids the deviation or loosening of the limiting plate 322 when adjusting the position of the connecting sleeve 321; at the same time, the detachability of the threaded connection also facilitates the replacement of the suitable limiting plate 322 according to the plate specifications in the later period, or the separate replacement of the limiting plate 322 after wear, without the need to disassemble the entire limiting assembly 320, thereby reducing the maintenance cost and operation difficulty.

[0039] As the limiting unit directly contacting the plate to be processed 500, the stop part 3222 has a cross-sectional diameter greater than that of the assembly part 3221, which can ensure sufficient and stable contact area with the side wall of the plate. During the position adjustment stage before processing, the stop part 3222 moves with the assembly part 3221 to abut against the side wall of the plate, limits the lateral displacement of the plate through its own structural strength, indirectly locks the relative distance between the cutting module 314 and the edge of the plate, and then determines the processing depth of the chamfer groove; during the processing process, the stop part 3222 continuously maintains the abutting state with the side wall of the plate, which can effectively offset the lateral deviation force generated during the plate conveying process due to vibration and conveying deviation, prevent the plate from deviating from the preset processing path to cause the cutting depth to fluctuate, and ensure that the cutting module 314 always processes chamfering with the preset depth.
