Description

Technical Field

[0001] This utility model relates to the field of CNC drilling machine technology, specifically a CNC drilling machine fixing fixture. Background Technology

[0002] CNC drilling machines are mainly used for drilling, reaming, boring, and tapping. They are numerically controlled machine tools primarily used for drilling. Due to the development of machining centers, the vast majority of CNC drilling machines have been replaced by machining centers. They are the preferred choice in the automotive, locomotive, shipbuilding, aerospace, and construction machinery industries, especially for drilling various large parts with multiple holes, such as ultra-long stacked plates, longitudinal beams, structural steel, and tubular components.

[0003] A search revealed a CNC drilling machine fixing fixture disclosed in Chinese Patent Publication No. CN216298060U. The key technical features are as follows: This utility model includes a worktable, a support plate fixed to the top of the worktable, a first screw threaded through one side of the support plate, a first fixing block fixed to one side of the first screw, a slot on one side of the first fixing block, and an mounting block fixed to one side of the first fixing block by a second screw. By setting up the first screw, second fixing block, first clamping block, and protective pad, the operator places the workpiece on the worktable. By turning the first screws on both sides of the support plate, the movable blocks fixed to the two first fixing blocks slide on the slide rod, causing the two first fixing blocks to move relative to each other until the protective pad on one side of the second clamping block is in contact with both sides of the workpiece. Simultaneously, an electric push rod located on one side of the second fixing block pushes the first clamping block towards the workpiece position.

[0004] However, the existing technology lacks an adjustment mechanism, which makes it inconvenient to adjust the tilt angle of the workpiece and to make and process the inclined hole. In order to solve the deficiency of the lack of an angle adjustment mechanism in the existing technology, this application drives the worktable and other components to tilt by the first drive bar and the first support rod, so that the worktable drives the workpiece to rotate, thereby achieving the effect of adjusting the tilt angle of the workpiece. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The above-mentioned background technology addresses the shortcomings and defects of existing technologies, such as the lack of an angle adjustment mechanism.

[0007] Furthermore, the worktable has two first sliders slidably connected inside, and a first screw is rotatably connected inside.

[0008] Furthermore, the worktable has two second sliders slidably connected inside, and a second screw is rotatably connected inside.

[0009] Furthermore, the upper surface of the workbench is provided with four first sliding grooves and four second sliding grooves.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up components such as a first drive bar and a first support rod, and through the mutual cooperation between the first drive bar and the first support rod, enables the first drive bar and the first support rod to drive the worktable and other components to rotate, thereby achieving the effect of tilting the workpiece by setting up components such as the first drive bar and the first support rod. This solves the shortcomings of current technical solutions that lack adjustment mechanisms and are not convenient for adjusting the tilt angle of the workpiece.

[0015] 2. By setting a second drive bar and a second support rod, and through the cooperation between the second drive bar and the second support rod, the second drive bar can drive the lifting plate and other components to move up and down through the second support rod, thereby achieving the effect of adjusting the height of the worktable by setting a second drive bar and a second support rod.
