Description

Technical Field

[0001] This utility model relates to the field of plate chamfering technology, and in particular to a plate rhombus arc milling machine. Background Technology

[0002] During the manufacturing process, burrs often appear on the edges and corners of workpieces and holes. These burrs not only affect the appearance quality of the workpiece but may also adversely affect subsequent processes and even the performance of the workpiece. Therefore, chamfering the edges of workpieces is an important and indispensable step in the machining process. Chamfering not only helps remove burrs but also improves the mechanical strength of the workpiece and enhances assembly accuracy, especially in precision machining processes with stringent requirements.

[0003] Traditional chamfering machines primarily process the edges of workpieces using beveling, typically resulting in a straight-edged profile. While these machines can fulfill basic chamfering requirements in most cases, they have certain design limitations. Existing chamfering machines generally lack the ability to round off the diagonal edges of workpieces. This means that when processing workpieces with complex shapes or requiring higher precision, the diagonal edges often retain sharp right angles or edge defects, failing to meet the requirements of specific applications. For example, the existing technology represented by the pneumatic chamfering machine with patent number CN 217475341 U, although capable of effectively performing straight chamfering operations, cannot achieve the desired rounded chamfer effect for certain workpieces, especially thin sheet materials, due to its design limitations. For a long time, this design deficiency has made processing workpieces requiring rounded chamfers on their diagonal edges difficult.

[0004] Based on this, the inventor proposes an innovative design to overcome the shortcomings of existing chamfering machines. By using a circular arc milling machine to process the diagonal edges of the workpiece, the sharp right-angled edges at the diagonal of the workpiece can be processed into smooth circular arc shapes, thereby effectively removing burrs, improving the appearance of the workpiece, and enhancing its performance and assembly accuracy.

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] A sheet metal corner milling machine includes a rotating mechanism, a rotating cutter head assembly, an edge trimming assembly, and a guide assembly.

The cutter head assembly is opposite to the notch, and a gap is maintained between them. The guide assembly includes a fixing member and a guide member that moves along the fixing member. The fixing member is fixedly connected to the edge trimming assembly. The rotating cutter head assembly is fixedly connected to the guide assembly. During the guiding movement, the notch at the end of the plate body can move to be on the same plane as the cutter head assembly. The end cutter of the cutter head assembly is an arc shape capable of cutting sheet metal.

[0007] Furthermore, the rotary cutter head assembly also includes a base fixedly connected to the rotary mechanism, the cutter head assembly is mounted on the base, and the rear end of the cutter head assembly is connected to the drive shaft of the rotary mechanism; the cutter head assembly includes a rotary shaft platform, the front end of the rotary shaft platform is provided with at least one opening, an arc-shaped cutter is assembled in the opening, and the arc-shaped cutter protrudes outside the rotary shaft platform.

[0008] Furthermore, the plate is triangular in shape, and assembly seats are provided on the outer sides of the two edge plates on the plate; wherein, the two edge plates and the two assembly seats are symmetrically arranged on both sides of the straight line formed by the notch of the triangular plate and the center of the third side; the fixing parts on the guide are correspondingly installed on the assembly seats.

[0009] Furthermore, the fixing component is a base, on which a guide post is loaded. A spring is provided on the outside of the guide post, and the spring abuts against the base. The guide component is a guide sleeve sleeved on the corresponding guide post. A limiting assembly pin is provided on the guide sleeve along the guide post.

At the same time, a connecting plate is provided between the two guide sleeves. An extension plate is provided on the outside of the connecting plate. A slot is provided on the base body, and the extension plate is locked in the slot and tightly assembled with the base body.

[0010] Furthermore, it also includes an adjustment assembly for cutting the curvature of the sheet metal; the adjustment assembly includes an adjusting threaded rod extending through the seat into the slot, and an internal thread that is threaded to the end of the extended plate and connected to the adjusting threaded rod, while a sliding guide rail is matched between the side wall of the extended plate and the inner side of the slot.

[0011] Furthermore, it also includes a fixing pin that passes through the base and the extension plate assembly, and a fine-tuning slot on the base for fixing the movement of the pin.

[0012] The beneficial effects of this utility model are:

[0013] (1) Mainly completes the arc-shaped machining of the diagonal edges of the workpiece to make it into an arc shape;

[0014] (2) The design mainly uses a combination of a rotary cutter head assembly, an edge trimming assembly, and a guide assembly. The rotary cutter head adopts a special arc-shaped cutter head.

[0027] Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings; many specific details are set forth in the following description in order to provide a full understanding of this utility model; however, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0029] It should be noted that the directional terms such as up, down, front, back, left, and right used in this application are all in the form of... Figure 1 Based on the orientation shown, the present invention will be further described below with reference to the accompanying drawings.

[0030] Please see Figures 1-8 This utility model includes a rotating mechanism 1, and also includes a rotating cutter head assembly 2, an edge-aligning assembly 3, and a guide assembly 4. The rotating cutter head assembly 2 includes a cutter head assembly 201 connected to the drive shaft of the rotating mechanism 1. The edge-aligning assembly 3 includes a plate 301, on which two edge plates 302 for aligning with the two sides of the processed material are protruding, and a notch 204 is provided at the end of the plate 301. The cutter head assembly 201 is opposite to the notch 204, and a gap 304 is maintained between them. The guide assembly 4 includes a fixing member 401 and a guide member 402 that moves along the fixing member 401. The fixing member 401 is fixedly connected to the edge-aligning assembly 3. The rotating cutter head assembly 2 is fixedly connected to the guide assembly 4. When the guide assembly 4 moves, the notch 204 at the end of the plate 301 can move to be on the same plane as the cutter head assembly 201. The cutter head at the end of the cutter head assembly 201 is arc-shaped and can cut the material.

[0031] This technology relates to a high-efficiency sheet metal workpiece processing equipment, mainly composed of a rotating mechanism 1, a rotating cutter head assembly 2, an edge-aligning assembly 3, and a guide assembly 4. The rotating cutter head assembly 2 includes a cutter head assembly 201 connected to the drive shaft of the rotating mechanism 1. The cutter head assembly 201 rotates under the drive of the rotating mechanism 1, thereby completing the precision processing of the edges of the sheet metal workpiece. The edge-aligning assembly 3 consists of a plate body 301 with two protruding edge plates 302 for precisely aligning the two sides of the sheet metal. A notch 204 is provided at the end of the plate body 301, and the rotating cutter head assembly 201 is opposite to this notch 204. When the sheet metal is placed on the edge-aligning assembly 3, the diagonal edges of the sheet metal extend into the notch 204 and are exposed for positioning, ensuring that the exposed portion of the sheet metal is directly perpendicular to the rotating cutter head assembly 2.

[0032] The guide assembly 4 consists of a fixing member 401 and a guide member 402 that moves along the fixing member 401. The fixing member 401 is tightly fixedly connected to the edge-flush assembly 3, ensuring that the edge-flush assembly 3 and the fixing member 401 are assembled as a single unit. The rotating cutter head assembly 2 is precisely fixedly connected to the guide assembly 4, ensuring that the rotating cutter head assembly 2 is firmly connected to the guide assembly 4 during operation, thus guaranteeing the stability and accuracy of the cutter head assembly 201 during processing. The end of the cutter head assembly 201 is equipped with an arc-shaped cutter body, specially designed to cut sheet metal. The arc design of the cutter body ensures precise arc-shaped machining of the edges of the sheet metal workpiece.

[0033] In terms of working principle, when the guide assembly 4 moves, the end notch 204 of the plate 301 can move to be on the same plane as the end of the cutter head assembly 201. This process ensures that the end of the cutter head assembly 201 contacts the exposed part of the plate, and begins to perform arc-shaped machining on the edge of the plate workpiece. As the cutter head assembly 201 rotates, the cutter body continuously cuts the surface of the plate, gradually machining the original edge of the plate workpiece into a smooth, flat arc shape. The entire process not only removes burrs and irregular shapes from the plate edge, but more importantly, it makes the plate edge smoother, suitable for subsequent splicing or use.

[0034] Specifically, the rotary cutter head assembly 2 is one of the core components of this invention. It includes a base 202 fixedly connected to the rotary mechanism 1. The base 202 has a plate-like structure. The cutter head assembly 201 is mounted on the front end of the base 202, and the rear end of the cutter head assembly 201 is connected to the drive shaft of the rotary mechanism 1. The main function of the base 202 is to ensure a stable connection between the cutter head assembly 201 and the rotary mechanism 1, ensuring the efficient operation of the entire rotary system. During the driving process of the rotary mechanism 1, the power of the rotary mechanism 1 is transmitted to the rotary cutter head assembly 2 through the base 202, thereby driving the cutter head assembly 201 to rotate for machining.

[0035] The core structure of the cutter head assembly 201 includes a rotary table 203. The rotary table 203 is located at the center of the cutter head assembly 201 and is mechanically fixed to the drive shaft of the rotating mechanism 1. Multiple openings 303 are provided at the front end of the rotary table 203 for mounting arc-shaped cutting tools 205. Each opening 303 houses one arc-shaped cutting tool 205; the arc design of the tool is intended to achieve precise arc-shaped cutting of the edges of the sheet metal workpiece. The outer portion of the arc-shaped cutting tool 205 protrudes from the rotary table 203, ensuring that the tool can contact the edges and corners of the sheet metal workpiece during rotation.

[0036] These arc-shaped cutting tools 205 are mounted on the side of the rotary table 203 and rotate during the rotation of the rotary table 203. As the rotary table 203 rotates, the exposed arc-shaped cutting tools 205 continuously act on the edges and corners of the sheet metal workpiece in a rotating manner. These cutting tools can precisely contact the exposed edges and corners of the sheet metal workpiece to perform machining, completing the arc-shaped cutting of the edge of the sheet metal workpiece. Specifically, during the rotation of the cutter head assembly 201, a continuous rotary cutting path is formed by the arc-shaped cutting tools 205 at different positions, which ensures that the diagonal edges of the sheet metal workpiece are smoothly and uniformly machined into a smooth arc shape.

[0037] Regarding the specific design of plate 301, plate 301 is triangular in shape, and assembly seats 305 are provided on the outer sides of two edge plates 302 on plate 301. The two edge plates 302 and the two assembly seats 305 are symmetrically arranged on both sides of the straight line formed by the notch 204 and the center of the third side of the triangular plate 301. The fixing members 401 on the guide member 402 are correspondingly installed on the assembly seats 305 for fixation. Specifically, the notch 204 and the center point of the third side of the triangular plate 301 form a straight line, designed to provide a precise positioning reference line. This symmetrical layout ensures that the positions of the two edge plates 302 and the assembly seats 305 are symmetrical and precise, thereby ensuring that the sheet metal workpiece can be accurately aligned and positioned on plate 301. When the sheet metal workpiece is placed, its two sides are fixed by the edge plates 302, forming a clamping and alignment mechanism to ensure the stability of the sheet metal workpiece during processing. Furthermore, the fixing members 401 on the guide member 402 achieve stable installation through docking with the assembly seats 305. The matching design of the fixing member 401 and the assembly base 305 ensures that the guide assembly 4 can be firmly assembled with the edge-flush assembly 3, providing a stable guiding function. Specifically, the assembly base 305 not only provides a stable connection platform, but also, through its matching with the fixing member 401 of the guide member 402, allows the guide member 402 to move along a fixed path, thereby guiding the rotary cutter head assembly 2 to precisely process the sheet metal workpiece.

[0038] In this design, the core structure of the guide assembly 4 includes several important components, such as the base 403, guide post 404, spring 405, guide sleeve 406, limiting assembly pin 407, connecting plate 410, extension plate 411, and slot 412. These components together form a precise guiding system, ensuring that the notch 204 of the edge-aligning assembly 3 moves relative to the rotating cutter head assembly 2 in a precise displacement on the same plane under the action of the guide assembly 4. The base 403 is the basic component of the guide assembly 4, serving to support and fix the edge-aligning assembly 3. The guide post 404 on the base 403 is installed in a suitable position, and a spring 405 is fitted on the outside of the guide post 404. The spring 405 provides elastic support, ensuring that the guide post 404 maintains appropriate pressure and position during movement, preventing excessive offset or loosening of the guide post 404. The guide post 404 is one of the key components of the guiding system, with a spring 405 mounted on its outside. One end of the spring 405 abuts against the base 403, and the other end provides a counterforce. The function of the spring 405 is to maintain the initial position of the guide post 404 and provide sufficient elastic support when the guide assembly 4 moves, allowing the guide sleeve 406 to move smoothly and stably along the guide post 404. The guide post 404 ensures that the guide member 402 (guide sleeve 406) moves accurately along a predetermined trajectory, avoiding any unnecessary deviation. The guide member 402 consists of the guide sleeve 406 sleeved on the guide post 404. The guide sleeve 406 is a sliding component in the guide system; it surrounds the guide post 404, allowing the guide post 404 to move smoothly within the guide sleeve 406. A limiting assembly pin 407 is provided on the guide sleeve 406 along the direction of the guide post 404. The function of the pin is to limit the range of movement of the guide sleeve 406 on the guide post 404. By setting the limiting position of the pin, it can be ensured that the relative movement of the guide sleeve 406 and the guide post 404 does not exceed a predetermined range, thereby ensuring the accuracy and stability of the guide system. The guide sleeve 406 is provided with a limiting assembly pin 407, while the guide post 404 is provided with a hole 408 to accommodate the assembly pin 407. The assembly pin 407 moves along a trajectory within the hole 408, and an abutment portion 409 is provided on the outer side of the pin and the upper end of the hole 408. The design of the abutment portion 409 allows the pin to contact the limiting part at the upper end of the hole 408 during movement, thereby limiting the range of movement of the guide sleeve 406, preventing excessive displacement, and ensuring that the guide sleeve 406 remains stable on the guide post 404. A connecting plate 410 is provided between the two guide sleeves 406. The function of the connecting plate 410 is to fix the two guide sleeves 406 together, maintain an appropriate distance between them, and ensure that the guide sleeves 406 remain parallel during movement. An extension plate 411 is provided on the outer side of the connecting plate 410, and the extension plate 411 cooperates with the slot 412 of the seat 202. The extension plate 411 is inserted into the seat 202 through the slot 412 and is tightly assembled with the seat 202, thereby ensuring the stability and accuracy of the connecting plate 410 and the guide sleeve 406.The base 202 is provided with a slot 412 for receiving the extension plate 411. After the extension plate 411 is inserted into the slot 412, it can be tightly assembled with the base 202, ensuring that the guide assembly 4 does not shift or loosen during operation. The slot 412 is designed to ensure the fixed relationship between the connecting plate 410 and the guide sleeve 406, so that the entire guide system can operate stably and reduce vibration or errors during operation.

[0039] The above describes the overall structure assembly and working principle of this utility model.

[0040] In order to further adjust and meet the curvature cutting requirements of sheet metal workpieces, this processing equipment also includes an adjustment component 5 for sheet metal curvature cutting. The adjustment component 5 includes an adjusting threaded rod 501 extending through the base 202 into the slot 412, and an internal thread 502 that is threadedly connected to the adjusting threaded rod 501 at the end of the extension plate 411. At the same time, a sliding guide rail 503 is matched between the side wall of the extension plate 411 and the inner side of the slot 412. That is, the sliding guide rail 503 on the inner side of the extension plate 411 and the slot 412 are engaged, and the threaded connection between the adjusting threaded rod and the extension plate 411 is engaged. During the rotation of the adjusting threaded rod 501, the extension plate 411 will move along the direction of the sliding guide rail 503. In turn, the extension plate 411 will drive the integrated guide component 4 and the edge-aligning component 3 to move, so that the notch 204 has an oblique displacement stroke relative to the rotating cutter head, which allows the curvature of the workpiece to be adjusted during cutting to meet the required requirements.

[0041] Meanwhile, the adjustment assembly 5 also includes a fixing pin 504 for use. The fixing pin 504 passes vertically through the base 202 and is assembled with the extension plate 411. The base 202 has a fine-tuning slot 505 for moving the fixing pin 504. The purpose of the fixing pin 504 is mainly to ensure the stability of the extension plate 411 when it moves along the sliding guide rail 503 and to limit the movement of the extension plate 411, so as to ensure that the distance between the arc-shaped tool 205 and the notch 204 is too large and the final processing of the sheet metal workpiece cannot be achieved.

[0042] Meanwhile, a handle 506 is provided on the plate 301 in the direction away from the edge plate 302.

[0043] The rotating mechanism 1 is designed to be vertical, such as... Figure 6As shown, the rotating mechanism 1 includes a vertical frame 102, inside which is a rotating body 103 and a controller 104. In this technology, after the sheet metal workpiece is placed on the edge-aligning assembly 3 for positioning from top to bottom, the rotating body 103 inside the vertical frame 102 is simultaneously activated by the controller 104 to drive the rotating cutter head assembly 2. By pressing down on the sheet metal workpiece, the edge-aligning assembly 3 is driven to make the sheet metal workpiece exposed in the notch 204 part contact the arc-shaped cutter 205, thus completing the final processing.

[0044] Meanwhile, in the design of the rotating mechanism 1, an insertion hole is provided at the back end of the adjusting threaded rod 501. The main function of the insertion hole is to insert a column, which facilitates the rotation of the adjusting threaded rod 501 and thus controls the displacement of the extension plate 411.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
