Description

Technical Field

[0001] The utility model belongs to the technical field of machining, and particularly relates to a four-axis drilling and milling tooling. Background Art

[0002] The four-axis dividing head drills holes, taps threads, mills the end faces of short-axis products, etc. Each processing requires multiple clampings, and after processing, it is easy to cause large form and position tolerances of the workpieces. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a four-axis drilling and milling tooling aiming at the deficiencies of the above-mentioned prior art. It can complete the processing of the end face of the workpiece under one clamping and ensure the form and position tolerances at both ends of the part.

[0004] The technical solution adopted by the utility model is: a four-axis drilling and milling tooling, including a working plate, on which four V-shaped grooves are formed. An end face positioning block is fixedly installed between two V-shaped grooves, and both ends of the end face positioning block are respectively located at the edges of the two V-shaped grooves close to each other. A locking hole is also formed in the middle between the two V-shaped grooves. A locking rod that is threadedly engaged with it is provided in the locking hole. A pressing strip is installed on the upper part of the locking rod, and a locking nut is provided at the end of the locking rod. Both ends of the pressing strip are aligned with the edges of the two V-shaped grooves away from each other.

[0005] Preferably, positioning grooves are formed at both ends of the end face positioning block.

[0006] Preferably, a spring is sleeved on the locking rod between the pressing strip and the working plate.

[0007] The beneficial effects of the utility model are as follows: The utility model adopts V-shaped clamping pressure, and can perform operations such as drilling, tapping, and milling on four workstations at one time. During the four-axis processing, it can effectively reduce the auxiliary time of multiple clampings, improve production efficiency, and at the same time ensure the form and position tolerances at both ends of the part.

[0010] The following will further describe the utility model in detail with reference to the drawings and specific embodiments.

[0011] Embodiment

[0012] As Figure 1As shown in the figure, the four-axis drilling and milling tooling provided in this embodiment includes a working plate 1, which is extended on the working surface of a four-axis indexing head. Four V-shaped grooves 2 are formed on the working plate 1. An end face positioning block 3 is fixedly installed between two V-shaped grooves 2. Both ends of the end face positioning block 3 are located at the edges of the two V-shaped grooves 2 close to each other, and end face positioning grooves are respectively opened at both ends of the end face positioning block 3. A locking hole is also opened in the middle between the two V-shaped grooves 2. A locking rod 4 that is threadedly engaged with it is provided in the locking hole. A pressing strip 5 is installed on the upper part of the locking rod 4, and a locking nut 6 is provided at the end of the locking rod 4. Both ends of the pressing strip 5 are aligned with the edges of the two V-shaped grooves 2 away from each other; a spring is sleeved on the locking rod 4 between the pressing strip 5 and the working plate 1.

[0013] During use, the outer cylindrical surface of the short-axis part is placed in the V-shaped groove 2, and the end face of the workpiece is positioned by the end face positioning block 3. After the workpiece is loaded into the V-shaped groove 2, the locking nut 6 is rotated to drive the locking rod 4 and the pressing strip 5 to displace, so that the pressing strip 5 presses against the outer cylindrical surface of the workpiece, realizing V-shaped clamping of the workpiece. After the processing is completed, the locking nut 6 is loosened, the pressing strip 5 leaves the workpiece, and the processed workpiece can be taken off.

[0014] The above is only the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and inventive concept provided by the present invention should be covered within the protection scope of the present invention.
