Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a drilling fixture for flanged parts. Background Technology

[0002] With the development of the manufacturing industry, the requirements for the precision and efficiency of parts processing are constantly increasing, and traditional drilling methods can no longer meet the processing needs of complex parts. Therefore, slant hole drilling fixtures have emerged and continue to develop with technological advancements. The main principle of slant hole drilling fixtures is to use specific structures and devices to enable the drill bit to drill into the workpiece at a predetermined angle and position, thereby achieving the processing of slant holes. Its structure typically includes a base, support plate, angle adjustment mechanism, clamping mechanism, and other parts.

[0003] When drilling angled holes in parts, the part must first be placed on an inclined base, and the drill jig should be as close as possible to the drilling position to ensure that the drill bit enters the workpiece at a precise angle and position. For products with flanges, due to the complex shape of the parts and limited installation space, the drill jig needs to be moved a certain distance via a slide table during installation to avoid the flanges. After the product is installed, it is then returned to the drilling position. During the drill jig reset process, wear and other issues can reduce positional accuracy, leading to quality problems. At the same time, the movement of the drill jig wastes time and reduces production efficiency. Summary of the Invention

[0004] Purpose of the utility model: In order to overcome the shortcomings of the prior art, this utility model requests protection for a drilling jig for flanged parts.

[0005] Technical solution: The drilling fixture for flanged parts disclosed in this utility model includes:

[0006] The base is fixed to the drilling rig platform and is equipped with an inclined fixing frame;

[0007] The base plate is bolted and fixed to the inclined fixing frame. The protruding part of the flange part corresponds to the inclined back side of the base plate and is positioned by the part positioning pin. The inclined front side of the base plate is open and fitted with a drill sleeve. The drill sleeve corresponds to the drilling position of the drilling machine and the drilling position of the flange part.

[0008] A fixed clamp includes a clamp base, a drive arm, and a pressing arm. The clamp base is bolted to a base plate. The drive arm is equipped with a handle. The pressing arm moves perpendicular to the base plate. By pushing the handle, the pressing arm is controlled to press the flange part tightly against the base plate.

[0009] Furthermore, the base is provided with bolting holes for bolting and fixing to the drilling rig platform.

[0010] Furthermore, the inclined back side of the base plate is provided with a positioning groove corresponding to the protruding part of the flange component.

[0011] Furthermore, a chip removal port is provided on the base plate at the position between the drill bushing and the flange component, and extends out to the bottom of the base plate.

[0012] Furthermore, a pad is provided between the clamp and the base plate.

[0013] Furthermore, the driving end of the extrusion arm is provided with a pressing head, and the extrusion cross section of the pressing head gradually increases from the extrusion arm to the flange zero.

[0014] Furthermore, the driving end of the extrusion arm is provided with a fixing nut, and the driving end of the pressing head is provided with a fixing screw that matches the thread of the fixing nut. The pressing force of the pressing head on the flange part is adjusted by the thread connection depth.

[0015] Beneficial effects: Compared with the prior art, the advantages of this utility model are as follows: the prefabricated inclined fixing frame ensures the tilt angle; the base plate and the base are positioned by pin holes and fastened by threads; the drill jig is embedded in the base plate and coaxial with the center of the drilling machine; the flange parts are installed on the clamp through the back of the inclined base and quickly fastened by the fixing clamp, thereby avoiding the situation of the drill jig sliding due to limited installation space and improving the convenience of installation; at the same time, it improves the accuracy of processing and the increase in production efficiency.
