Description

Technical Field

[0001] This application relates to the field of screw machining technology, and in particular to a tooling device for machining screw drills. Background Technology

[0002] Currently, most screw drills consist of a bypass valve assembly, an anti-drop assembly, a motor assembly, a universal joint assembly, and a drive shaft assembly. Among them, the universal joint assembly contains a bent joint with a curved structure and a housing with an inclined surface.

[0003] The existing process for processing elbow joints involves manually marking lines on the workpiece multiple times and then performing turning operations through multiple clamping and setups. This process involves rotating the workpiece multiple times during roughing, adjusting the machine tool angle, and machining surfaces at different angles to gradually approach the design dimensions.

[0004] The existing technical solutions mentioned above have the following drawbacks: they rely on manual marking, multiple clamping and adjustment, have a high proportion of preparation time, long processing cycles, and are controlled by manual experience, making it difficult to guarantee the consistency of mass production. Utility Model Content

[0005] This application provides a tooling device for machining screw drills in order to accurately and efficiently process and shape them.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A tooling device for machining screw drills includes a mounting column, which is a metal cylinder. A cylindrical receiving hole is provided on the end face of the mounting column. The receiving hole connects the two end faces of the mounting column. The axis of the receiving hole passes through the axis of the mounting column, and the intersection of the two axes is located outside the mounting column. There is an angle between the axis of the receiving hole and the axis of the mounting column.

[0008] By adopting the above technical solution, and by setting the mounting column and the receiving hole opened on the end face of the mounting column, when machining the screw drill workpiece, the mounting column is sleeved on the peripheral wall of the screw drill workpiece through the receiving hole. The mounting column is placed and clamped in the three-jaw chuck of the lathe. The receiving hole, which has an angle between its axis and the axis of the mounting column, allows the screw drill bending joint to be machined to be coaxial with the three-jaw chuck, which facilitates subsequent machining, reduces the preparation time of manual scribing, multiple clamping and adjustment, and shortens the machining cycle. At the same time, it allows the tooling to adapt to the machining requirements of the screw drill bending structure, reduces the situation of controlling the workpiece machining progress by manual experience, and improves the machining efficiency of the screw drill workpiece.

[0009] Optionally, the end face of the mounting post is marked with the location of the bend.

[0010] By adopting the above technical solution, the bending point position is marked, and during processing, the bending point position marked on the tooling end face is aligned with the bending point of the screw drill workpiece. By adjusting the distance between the tooling end face and the workpiece end face, the bending center axis of the two is made to coincide, ensuring that the curvature reference of the bending structure processing is unified and avoiding shape errors caused by bending point offset.

[0011] Optionally, the inner wall of the receiving hole is provided with an adjustable notch, which connects the receiving hole and the outer wall of the mounting column, and the adjustable notch is provided with openings on both ends of the mounting column.

[0012] By adopting the above technical solution, and by setting an adjustable notch, the screw drill workpiece can be easily placed into the receiving hole. When the chuck retracts, the mounting column is subjected to external force, and the gap in the peripheral wall allows it to deform, so that the tooling fits tightly against the workpiece surface, thereby clamping the workpiece, reducing the possibility of workpiece displacement during processing, and ensuring processing accuracy and stability.

[0013] Optionally, the walls of the receiving hole are smoothed.

[0014] By adopting the above technical solution and smoothing the wall of the receiving hole, the inner wall of the receiving hole fits tightly with the surface of the workpiece when machining the screw drill workpiece. The smooth wall of the receiving hole can reduce the possibility of damaging the surface of the screw drill workpiece.

[0015] Optionally, the end face of the mounting column is provided with four scales arranged in a cross shape around the axis of the mounting column.

[0016] By adopting the above technical solution, and by setting a scale, four scales are evenly distributed at equal angles on the end face of the mounting column with the axis of the mounting column as the center. Among them, two relatively distributed scales represent 0° and 180° respectively. When clamping, by aligning the corresponding angle lines of the mounting column and the screw drill workpiece, it can be ensured that the rotation reference of the two is consistent, reducing the machining position errors caused by angle deviation, thereby reducing the number of clamping times and improving the machining efficiency of the screw drill workpiece.

[0017] In summary, this application has the following technical effects:

[0018] 1. By setting up a mounting post and a receiving hole on the end face of the mounting post, when machining the screw drill workpiece, the mounting post is sleeved on the peripheral wall of the screw drill workpiece through the receiving hole. The mounting post is then placed and clamped in the three-jaw chuck of the lathe. The receiving hole, which has an angle between its axis and the axis of the mounting post, allows the screw drill bent joint to be machined to be coaxial with the three-jaw chuck, which facilitates subsequent machining, reduces the preparation time for manual scribing, multiple clamping and adjustment, and shortens the machining cycle. At the same time, it allows the tooling to adapt to the machining requirements of the screw drill bent structure, reduces the need to control the workpiece machining progress based on manual experience, and improves the machining efficiency of the screw drill workpiece.

[0019] 2. By setting an adjustable notch, the screw drill workpiece is easily placed into the receiving hole. When the chuck retracts, the mounting post is subjected to external force, and the gap in the peripheral wall allows it to deform, so that the tooling fits tightly against the workpiece surface, thereby clamping the workpiece, reducing the possibility of workpiece displacement during processing, and ensuring processing accuracy and stability.

[0020] 3. By setting a scale, four scales are evenly distributed at equal angles on the end face of the mounting post with the mounting post axis as the center. Among them, two oppositely distributed scales represent 0° and 180° respectively. When clamping, by aligning the corresponding angle lines of the mounting post and the screw drill workpiece, it can be ensured that the rotation reference of the two is consistent, reducing the machining position errors caused by angle deviation, thereby reducing the number of clamping times and improving the machining efficiency of the screw drill workpiece.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses a tooling device for machining screw drills, referring to... Figure 1 The tooling device includes a mounting column 1, which is a metal cylinder. A receiving hole 2 is formed on the inward-facing end of the mounting column 1, connecting both ends of the mounting column 1. The receiving hole 2 is cylindrical and has a smooth wall to reduce the possibility of damaging the surface of the screw drill workpiece. The axis of the receiving hole 2 passes through the axis of the mounting column 1, and there is an angle between the axis of the receiving hole 2 and the axis of the mounting column 1. The intersection of the axis of the receiving hole 2 and the axis of the mounting column 1 is located outside the mounting column. The mounting column 1 is fitted onto the peripheral wall of the screw drill workpiece through the receiving hole 2. The mounting column 1 is placed in the three-jaw chuck of a lathe, and the mounting column 1 is clamped by the three-jaw chuck, so that the screw drill bend to be processed is coaxial with the three-jaw chuck, facilitating subsequent processing of the screw drill. Compared with manual processing, auxiliary processing using the mounting column 1 can improve processing efficiency.

[0026] Combination Figure 1 and Figure 2The end face of mounting column 1 is marked with the position of the bend (not shown in the figure). During processing, the position of the bend marked on the end face of the tooling is aligned with the bend of the screw drill workpiece. By adjusting the distance between the end face of the tooling and the end face of the workpiece, the bending center axis of the two is made to coincide, ensuring that the curvature reference of the bending structure is consistent and avoiding shape errors caused by the offset of the bend.

[0027] Combination Figure 1 and Figure 2 An adjustable notch 3 is provided on the periphery of the receiving hole 2. The adjustable notch 3 connects the outer periphery of the mounting column 1 and the inner wall of the receiving hole 2. The length direction of the adjustable notch 3 is parallel to the axis of the mounting column 1. The adjustable notch 3 has openings on both ends of the mounting column 1. The adjustable notch 3 facilitates the insertion of the screw drill workpiece into the receiving hole 2. When the chuck retracts, the mounting column 1 is subjected to external force, and the gap in the periphery allows it to deform, so that the tooling fits tightly against the surface of the workpiece, thereby clamping the workpiece, reducing the possibility of workpiece displacement during processing, and ensuring processing accuracy and stability.

[0028] Combination Figure 1 and Figure 2 The end face of the mounting post 1 is cross-shaped with four graduations 4. The four graduations 4 are evenly spaced at equal angles around the axis of the mounting post 1. Two opposite graduations 4 represent 0° and 180° respectively. During clamping, by aligning the corresponding angle lines of the mounting post 1 and the screw drill workpiece, the rotation reference of the two is ensured to be consistent, reducing the machining position errors caused by angle deviation, thereby reducing the number of clamping operations and improving the machining efficiency of the screw drill workpiece.
