Description

Technical Field

[0001] This utility model relates to a grooving device, and in particular to a grooving device for arc-shaped plates. Background Technology

[0002] In the manufacturing of curved sheet metal parts, milling is often required to allow them to be bent into curved shapes. However, traditional milling methods typically rely on manual operation, with workers manually holding milling cutters. Because manual operation cannot guarantee the stability of the cutting tool or precise control of its position, it often results in uneven milled grooves, inconsistent depths, or even skewing on the sheet surface. This not only affects the processing quality but also increases production costs and time. Furthermore, while existing mechanized equipment offers some automation, it still lacks dedicated clamping and positioning systems for curved sheet metal parts; therefore, most operations and adjustments still depend on manual labor. Utility Model Content

[0003] This utility model provides a grooving device for arc plates, which aims to solve the problems of low accuracy, poor efficiency and lack of dedicated clamping and positioning system in the prior art of manual milling.

[0005] Material stop assembly, pressure plate assembly, milling device and moving mechanism;

[0006] The moving mechanism includes a slide rail fixedly mounted on a base, a slider slidably connected to the slide rail and fixedly connected to the milling device, wherein one end of the screw is connected to a handle, and the other end is connected to the slider in sequence through a bearing, a bearing mounting plate, a connecting plate, and a base plate. Threaded plates one and two are fixedly mounted on a limiting block and threadedly engaged with the screw. The pressure plate assembly includes a support plate vertically fixed to a baffle plate. The top of the support plate has a pair of ear holes, wherein the ear hole away from the direction of the workpiece is hinged to a hinged ear plate by a pin.

The Y-shaped end of the connecting arm is hinged to the handle and the ear hole of the support plate near the direction of the workpiece. A pressure head is fixedly mounted on the other end of the connecting arm.

[0007] Preferably, the slide rail is fixed to the base by a pad two, and the height of the pad two is not less than the thickness of the plate to be processed.

[0008] Preferably, the travel range of the limiting block is matched with the length of the machining groove.

[0010] Preferably, the bottom of the pressure head is provided with anti-slip texture, and the clamping surface is adapted to the contour of the workpiece being processed.

[0011] Preferably, the milling device includes a motor, a first gear, a belt, a second gear, and a milling cutter. The motor drives the first gear to rotate, and the belt drives the second gear to rotate synchronously. The second gear transmits power to the spline-connected milling cutter through an interference-fit connecting shaft, thereby realizing the high-speed rotational cutting motion of the milling cutter.

[0012] Preferably, a cover plate is provided on the outer side of the gear two, and the cover plate is fixedly connected to the base two by bolts.

Connecting plate 204 is fixedly connected to bearing mounting plate 209 by bolts.

[0032] The milling device 100 includes a base plate 106, which is fixedly connected to a slider 210. A baffle 113 is fixedly connected below the base plate 106 to prevent chip splashing during milling. The baffle 113 extends to cover the machining area of ​​the milling cutter 105.

The milling cutter 105 is connected to the connecting shaft 112 by spline.

[0033] Working Principle: The arc plate grooving device disclosed in this utility model positions the workpiece between the first baffle plate 302 and the second baffle plate 303 of the baffle assembly 300. The handle 403 of the pressure plate assembly 400 drives the pressure head 402 to clamp the workpiece through a lever-linkage mechanism. The start motor 101 drives the first gear 107 to the second gear 109 via the belt 108, which in turn drives the milling cutter 105 to rotate at high speed through the connecting shaft 112. At the same time, the handle 201 is rotated to make the screw 202 rotate, pushing the slider 210 to move linearly along the slide rail 211, thus driving the entire milling device 100 to complete the feed milling. The baffle plate 113 prevents debris from flying, and the cover plate 102 protects the transmission components. Through mechanical linkage, the positioning, clamping, milling and feed operations are integrated to ensure the accuracy and efficiency of arc plate grooving.
