Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for corner cutting and arc cutting machines, specifically to a positioning device for an electric corner cutting and arc cutting machine. Background Technology

[0002] Electric corner-cutting and arc-rounding machines, as key equipment for processing workpiece corners and arcs, have been widely used due to their high-efficiency cutting capabilities and convenient operation. The core function of this type of equipment is to precisely cut angles and form arcs on workpieces according to preset processing parameters. Accurate workpiece positioning during processing is a crucial prerequisite for ensuring the final dimensional accuracy, shape consistency, and workpiece pass rate, directly determining the smoothness of subsequent assembly processes and the overall quality level of the product. However, most mainstream electric corner-cutting and arc-rounding machines on the market currently rely on manual cutting by workers, depending on the operator's experience for manual calibration. During calibration, human error (such as deviations in stop position adjustment or inconsistent insertion depth of positioning pins) can easily lead to positioning datum shifts, directly resulting in workpieces that fail to meet the requirements of high-precision assembly and high-quality appearance. The generation of a large number of defective products not only increases the waste of raw materials and production costs but may also delay the production cycle, affecting the company's market competitiveness. Utility Model Content

[0003] The purpose of this invention is to provide a positioning device for an electric corner cutting and arc cutting machine, which solves the technical problems of low accuracy of workpiece corner cutting and reliance on operator experience in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A positioning device for an electric corner-cutting and rounding machine includes a support frame on which the corner-cutting and rounding machine is fixedly mounted; it also includes a moving component, an angle adjustment component, and a marking component; the moving component is mounted on the support frame and is used to move the workpiece horizontally and longitudinally; the angle adjustment component is disposed on the moving component and is used to adjust the tilt angle of the workpiece relative to the corner-cutting and rounding machine; the marking component is used to project marking lines onto the workpiece.

[0005] Preferably, the movable component is a cross slide mounted on the support frame.

[0006] Preferably, the angle adjustment component includes a scale plate and an adjustment plate, the scale plate being fixedly mounted on the movable component, and the adjustment plate being rotatably mounted on the movable component.

[0007] Preferably, the adjusting plate is provided with an L-shaped limiting member, and the workpiece is installed on the adjusting plate and locked on the L-shaped limiting member.

[0008] Preferably, a limiting block is provided on the support frame, the limiting block being used to limit the longitudinal movement distance of the moving component.

[0009] Preferably, the marking component is a laser emitter, and a marking sticker is provided at the end of the laser emitter. A cutting groove is provided on the marking sticker, and the laser emitted by the laser emitter is projected onto the surface of the workpiece through the cutting groove to form a marking line.

[0010] In this invention, the positioning device fundamentally solves the problem of insufficient positioning accuracy in traditional electric corner-cutting and arc-circling machines through multi-dimensional structural collaboration. On one hand, the cooperation between the scale plate and the adjustment plate in the angle adjustment component allows for precise measurement of the adjustment plate's rotation angle, avoiding angle deviations caused by experience-based adjustments in traditional mechanical limiters. On the other hand, the marking component projects marking lines via laser, visually mapping the cutting datum onto the workpiece surface, ensuring accuracy before cutting. Combined with the rigid positioning of the workpiece by the L-shaped limiter (or limit pin), it ensures precise alignment of the workpiece with the cutting datum each time it is installed. Simultaneously, the lateral movement of the moving component can be fixed with fasteners, achieving repeated accurate positioning after adjustment. During subsequent batch processing, only accurate positioning of the workpiece on the adjustment plate is required, avoiding processing deviations caused by manual calibration errors and mechanical wear drift. This significantly improves the consistency of workpiece corner and arc dimensions, reducing the defect rate.

[0011] The marking component uses laser-projected marking lines to quickly verify positioning accuracy, avoiding the cumbersome process of trial cutting to confirm positioning required by traditional equipment. Even inexperienced operators can complete the setup by following the simple steps of "positioning - calibration - fixing," significantly lowering the barrier to entry for using the equipment and reducing operational errors.

[0012] Improving processing efficiency and reducing production costs: In batch processing scenarios, this device enables "one-time calibration, repeated use," significantly shortening processing preparation time. After the initial calibration, subsequent workpieces only need to be accurately positioned on the adjustment plate using L-shaped limiters (or limit pins) for direct batch cutting. There's no need to readjust the position and angle of the moving components before each processing run. Compared to traditional equipment that requires recalibration every time a workpiece is changed, this significantly saves debugging time and improves processing efficiency. Simultaneously, precise positioning reduces raw material waste caused by processing deviations. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 The positioning device for an electric corner rounding machine shown includes a support frame 1, with the corner rounding machine 2 fixedly installed at the top center of the support frame 1. It also includes a moving component 3, an angle adjustment component 4, and a marking component 5. A set of moving components 3, angle adjustment components 4, and marking components 5 are respectively arranged on both sides of the corner rounding machine 2; one side is used for cutting right angles, and the other side is used for cutting rounded corners.

[0015] The moving component 3 is mounted on the support frame 1 and is used to move the workpiece 6 horizontally and longitudinally. The moving component 3 is a cross slide table set on the support frame 1. This cross slide table is a commercially available product, and its structure will not be described in detail in this manual. The lateral movement part can be fixed with fasteners to ensure accurate and repeatable positioning after adjustment. Of course, to improve the convenience of adjustment, an electric cross slide table can also be used.

[0016] An angle adjustment component 4 is mounted on the moving component 3 and is used to adjust the tilt angle of the workpiece 6 relative to the corner-cutting arc machine 2, thereby achieving the cutting of angles of different sizes. The angle adjustment component 4 includes a scale plate 40 and an adjustment plate 41. The scale plate 40 is fixedly mounted on the top of the moving component 3, and the adjustment plate 41 is rotatably mounted on the moving component 3 via bolts that also function as pins. After adjusting the adjustment plate 41 to the specified angle, the bolts are tightened to fix the adjustment plate 41 and maintain this position. The angle of rotation of the adjustment plate 41 is measured using the scale plate 40, improving the accuracy of the adjustment.

[0017] An L-shaped limiting member 42 is provided on the adjusting plate 41. The workpiece 6 is mounted on the adjusting plate 41 and locked onto the inner edge of the L-shaped limiting member 42. Alternatively, multiple limiting pins can be used to replace the L-shaped limiting member 42 to achieve positioning of the workpiece 6. The longitudinal movement of the moving component 3 can be either manually pushed or electrically driven.

[0018] A limiting block 7 is fixedly installed on the support frame 1. The limiting block 7 is used to limit the longitudinal movement distance of the moving component 3. Another extreme position of the longitudinal movement of the moving component 3 is when it contacts the chamfering and rounding machine 2.

[0019] The marking component 5 is used to project marking lines onto the workpiece 6. The marking component 5 is a laser emitter, and a marking sticker or marking cover is provided at the end of the laser emitter. A cutting groove is provided on the marking sticker or marking cover. The laser emitted by the laser emitter is projected onto the surface of the workpiece 6 through the cutting groove to form marking lines.

[0020] When the end of the limiting moving component 3 abuts against the limiting block 7, the lateral movement of the moving component 3 and the angle of the angle adjusting component 4 are adjusted so that the marking line emitted by the laser emitter is projected onto the surface of the workpiece 6. Then, the lateral movement of the adjusting component 3 and the angle of the angle adjusting component 4 are fixed. Subsequently, the workpiece 6 only needs to be accurately positioned and installed on the adjusting plate 41 to repeat batch precision cutting. When adjustment is required, the above steps are repeated.

[0021] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
