Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing equipment, and in particular to a bending boring tool. Background Technology
[0002] In existing technologies, when machining elbows on a boring machine, it is inconvenient to fix them because they are irregularly shaped parts. Even if existing fixtures are used to fix them, the fixation is not stable, which can easily lead to large machining errors during machining, affecting the quality of the machined elbows. Moreover, using existing fixtures to fix such elbows is time-consuming, labor-intensive, and inefficient. To solve the above problems, a new fixture is needed to fix elbows. Utility Model Content
[0003] The purpose of this utility model is to provide a bending head boring fixture to solve the problems of inconvenience in fixing bending heads when machining them with existing boring machines and poor stability after fixing.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A bending head boring fixture includes a base plate, a rotating disk, a bending support mechanism, and a bending clamping and fixing mechanism. The rotating disk is rotatably mounted on the top surface of the base plate. The rotating disk and the base plate are positioned by a locating pin located at the center. A rotating disk clamping mechanism is also provided next to the rotating disk on the top surface of the base plate. The bending support mechanism includes a support base with a bending placement groove on its top surface. The bending clamping and fixing mechanism includes a support rod, a horizontal pressure plate, and a first clamping screw. The support rod is vertically mounted on one side of the top surface of the rotating disk. The horizontal pressure plate is horizontally mounted, with one end connected to the support rod and the other end located above the support base. The first clamping screw is vertically mounted in the middle of the horizontal pressure plate, and a first clamping nut is provided above the first clamping screw. The bottom surface of the first clamping nut contacts the horizontal pressure plate.
[0005] A new elbow fixing fixture was designed. To fix it, simply place the elbow in the placement slot on top of the support base, and then tighten the first clamping nut downwards. As the first clamping nut moves downwards, it can clamp the elbow on top of the support base, making it easier to process. Moreover, since the support base is set on a rotating disk, the position of the support base can be adjusted by rotating the turntable, allowing workers to quickly clamp the elbow in the bend placement slot on top of the support base. During processing, the rotating disk is first fixed in its general position using the fixing pin in the middle, and then the rotating disk clamping mechanism is used to clamp it, avoiding large processing errors after processing.
[0006] As a further preferred embodiment of this utility model, the rotating disk clamping mechanism includes an "L"-shaped clamping plate and a second clamping screw. One end of the horizontal section of the "L"-shaped clamping plate is located above the rotating disk. The second clamping screw is vertically arranged in the middle of the horizontal section of the "L"-shaped clamping plate. A second clamping nut is also provided on the upper part of the second clamping screw. The bottom surface of the second clamping nut contacts the top surface of the horizontal section of the "L"-shaped clamping plate.
[0007] As a further preferred embodiment of this utility model, the rotary disc clamping mechanism has two or more sets.
[0008] As a further preferred embodiment of this utility model, the curved pipe placement groove is V-shaped.
[0009] As a further preferred embodiment of this utility model, the horizontal pressure plate includes a connecting section, a transition section, and an expanded pressing range section. The transition section is composed of two parallel transition section rods. The connecting section is located at the outer end of the transition section to connect the two parallel transition section rods. The support rod is located at the connecting section. The expanded pressing range section is located at the inner end of the transition section and is composed of two expanded pressing range section rods arranged in a figure-eight shape. The connection point between the expanded pressing range section rods and the transition section rods is the point where the distance between the two expanded pressing range section rods is the smallest.
[0010] The expanded clamping range section of the rod, arranged in a figure-eight shape, can more stably press down on the bend after being pressed down.
[0011] As a further preferred embodiment of this invention, the connecting segment is arc-shaped.
[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. It can easily and quickly fix elbows.
[0013] 2. Once the elbow is properly secured, it exhibits good stability. Attached Figure Description

The bottom surface of the first clamping nut 6 is in contact with the horizontal pressure plate 42.
[0024] A new elbow fixing fixture was designed. For fixing, simply place the elbow in the slot on top of the support base, then tighten the first clamping nut downwards. As the first clamping nut moves downwards, it clamps the elbow on top of the support base, facilitating processing. Furthermore, since the support base is mounted on a rotating disk, rotating the disk adjusts the position of the support base, allowing workers to quickly and easily clamp the elbow into the bend slot on top of the support base. During processing, first, the fixing pin in the center of the rotating disk is used to fix the overall position of the rotating disk, and then the rotating disk clamping mechanism is used to clamp it, preventing damage after processing. Significant processing errors occurred. Specific Implementation Example 2
