Description

Technical Field

[0001] This utility model belongs to the field of vertical drill bushing technology, and more specifically, it relates to a vertical drill bushing for machining aerospace parts. Background Technology

[0002] A vertical drill bushing is a metal sleeve fixed to a fixture with a high-precision guide hole inside. It is specifically designed to guide tools such as drill bits and reamers to drill vertically. In the aerospace field, high-precision drilling is required when manufacturing components such as aircraft engine blades and fuselage frames. Vertical drill bushings are indispensable tools because they ensure that the drill bit remains vertical during the drilling process, thereby improving product quality and reliability.

[0003] Based on existing technology, it has been found that when using existing vertical drill bushings, the vertical drill bit is usually in close contact with the top of the workpiece during machining. The accumulation of chips will increase the friction between the drill bit and the chips, increase the cutting resistance and generate high temperature, and increase the risk of drill bit jamming or uneven force, thus affecting drilling accuracy. In addition, existing vertical drill bushings are usually installed on the locator by threading. When drilling continuously in areas with uneven surfaces, it is not possible to easily adjust the height of the vertical drill bushing to meet the drilling requirements, resulting in poor practicality. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a vertical drill bushing for machining aerospace parts. This solves the problems of existing vertical drill bushings where the vertical drill bit typically adheres to the top of the workpiece during machining, leading to chip accumulation and increased friction between the drill bit and chips, thus affecting drilling accuracy. Furthermore, existing vertical drill bushings cannot easily adjust their height to suit drilling needs, resulting in poor practicality.

[0005] This utility model discloses a vertical drill bushing for machining aerospace parts, achieved through the following specific technical means:

[0006] A vertical drill bushing for machining aerospace parts includes a guide part, a positioning part, a fixing part, and a locking part;

[0007] The guide part is mounted on the positioning part; the fixing part is located on the top of the positioning part and is connected to the guide part; the locking part is located on the fixing part and is connected to the guide part.

[0008] The guide portion includes: a main body; a circular hole is provided inside the main body;

[0009] The fixing part includes: a fixing member, which is configured as a circular ring structure; a main body is slidably installed inside the fixing member; a contact member is provided on the top of the fixing member below; the side of the contact member contacts the main body;

[0011] Furthermore, the guide portion also includes: a chip removal groove;

[0012] The chip removal groove is located on the bottom side of the main body; there are three sets of chip removal grooves in total.

[0013] Furthermore, the positioning part includes: a positioning element and a mounting rod;

[0014] The positioning component has a circular hole; a main body is slidably installed inside the circular hole of the positioning component; a fixing component is fixedly installed on the top of the positioning component; and the mounting rod is fixedly installed on both sides of the positioning component.

[0015] Furthermore, the positioning part also includes: a screw and a clamping member;

[0016] The screw is positioned in the middle of the positioning member; a rotating handle is provided on the screw; the clamping member is located on the left and right sides of the positioning member; the clamping member is slidably mounted on the mounting rod; the clamping member is mounted on the screw.

[0017] Furthermore, the top of the contact element is configured with an inclined structure; the side of the contact element is provided with an arc-shaped groove; and the contact element is made of an elastic material.

[0018] Furthermore, the fixing part also includes: a connecting rod;

[0019] The connecting rod is fixedly installed between the fixing parts on the upper and lower sides; a locking part is slidably installed on the connecting rod.

[0020] Furthermore, the top of the inner groove is configured as an inclined structure.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In this device, a chip removal hole is provided. The chip removal groove is opened at the bottom of the main body, so that when drilling, the waste chips generated during use can be directly discharged through the chip removal groove, avoiding the accumulation of waste chips around the hole, reducing the friction between waste chips and drill bit, preventing drill bit jamming or uneven force, reducing drill bit shaking and wear during drilling, extending the service life of drill bit, and improving drilling accuracy.

[0023] 2. This device includes a fixing component and a locking component. The fixing component is fixedly installed at the bottom of the positioning component, while the locking component is connected to the fixing component via a spring. During use, by pulling the locking component upwards, it moves on the connecting rod and compresses the spring, allowing for free adjustment of the sliding depth of the main body within the positioning component. This ensures better contact between the bottom of the main body and the workpiece. The spring then resets, causing the locking component to move. The top of the inner groove of the locking component contacts the inclined surface of the top of the contact component, thus squeezing the contact component and locking the main body in position. This makes operation more convenient and practical. Attached Figure Description
