Description

Technical Field

[0001] This utility model relates to the field of milling equipment technology, specifically to an internal pressure structure anti-chip jamming angle milling head. Background Technology

[0002] The internal pressure structure anti-chip jamming angle milling head is a specially designed machine tool accessory aimed at solving the chip jamming problem that may occur during the use of traditional angle milling heads. During machining, especially when performing deep hole drilling or machining complex curved surfaces, chips easily accumulate in the internal structure of the angle milling head, leading to chip jamming. This not only affects machining quality but may also damage the machine tool and the angle milling head.

[0003] The existing technology still has the following drawbacks in its use:

[0004] Existing angle milling heads typically use an external pressure plate and internal pin positioning structure, which poses significant safety risks. The harsh operating conditions of angle milling heads during machine processing, including the splashing of metal chips and other machining debris, cause the positioning plates to spring back unevenly, resulting in inaccurate positioning.

[0005] In view of this, we propose an internal pressure structure anti-chip jamming angle milling head to solve the existing problems. Utility Model Content

[0006] The purpose of this invention is to provide an internal pressure structure anti-chip jamming angle milling head to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an internal pressure structure anti-chip jamming angle milling head, including a drive tool holder, a clamping ring installed at the front end of the drive tool holder, a positioning pin sleeve connected to the lower end of the clamping ring, a cross pin connected to the lower end of the drive tool holder near the positioning pin sleeve, a positioning pin connected to one side of the positioning pin sleeve, a spring connected inward to the positioning pin, and an internally threaded cylindrical pin installed at the connection between the positioning pin sleeve and the clamping ring.

[0008] Preferably, a clamping ring nut is provided at the upper end of the clamping ring, an internal hexagon screw is installed between the clamping ring nuts, and a washer is installed on one side of the clamping ring nut.

[0009] Preferably, a graduated ring is installed at the front end of the drive tool holder.

[0010] Preferably, the locating pin sleeve has a lower cover installed on the side near the spring.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention, through the addition of a positioning pin and a built-in spring, significantly increases the reliability and service life of the positioning mechanism without altering its function or increasing costs. It also solves the problem of uneven return of the positioning paddle during the milling process, preventing installation issues caused by positioning failures and providing customers with a higher-quality product.

[0018] like Figure 1 and Figure 2 As shown, the present invention proposes an internal pressure structure anti-chip jamming angle milling head, including a drive tool holder 1. A clamping ring 3 is installed at the front end of the drive tool holder 1. The clamping ring 3 provides necessary support for the milling head, enabling it to withstand various forces and vibrations during the machining process and maintain a stable operating state. A positioning pin sleeve 2 is connected to the lower end of the clamping ring 3. The positioning pin sleeve 2 is used to install positioning pins 12 and other components. A horizontal pin 11 is connected to the lower end of the drive tool holder 1 near the positioning pin sleeve 2. The horizontal pin 11 is used to stably connect the positioning pin sleeve 2 and the drive tool holder 1. A positioning pin 12 is connected to one side of the positioning pin sleeve 2. The positioning pin 12 is used to achieve precise positioning of the milling head, thereby avoiding chip jamming. A spring 10 is connected inward to the positioning pin 12. An internally threaded cylindrical pin 9 is installed at the connection between the positioning pin sleeve 2 and the clamping ring 3.
