Description

Technical Field

[0001] This utility model belongs to the field of powder metallurgy production technology, specifically relating to a drilling fixture for powder metallurgy parts. Background Technology

[0002] Powder metallurgy is a process technology that uses metal powders (or mixtures of metal and non-metal powders) as raw materials, followed by forming and sintering, to manufacture metallic materials, composite materials, and various types of products. Powder metallurgy shares similarities with ceramic production, both belonging to powder sintering technology; therefore, a range of new powder metallurgy technologies can also be applied to the preparation of ceramic materials. Due to its advantages, powder metallurgy has become a key to solving new materials problems and plays a crucial role in the development of new materials.

[0003] Powder metallurgy requires high-temperature sintering followed by room-temperature cooling during production. During this process, thermal expansion and contraction can cause errors in various dimensions, affecting assembly accuracy. Therefore, secondary processing is required for the main assembly dimensions after forming, such as the inner diameter of holes and shafts. However, currently, this is mainly done manually using machine tools for drilling, which is inefficient. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A drilling fixture for powder metallurgy parts includes a frame body and an X-axis assembly and a Y-axis assembly mounted on the frame body. A drilling assembly is mounted on the Y-axis assembly, and the X-axis assembly and Y-axis assembly are used to drive the drilling assembly to move along the X-axis and Y-axis, respectively.

[0006] The drilling assembly includes a third drive element and a pneumatic clamp connected to the third drive element, the pneumatic clamp being connected to a drill bit; the pneumatic clamp is used to clamp / release the drill bit;

[0007] The frame body is also equipped with a fixing component and a tool changing component; the tool changing component includes a tool head holder and several replacement drill bits disposed on the tool head holder.

[0008] Furthermore, the pneumatic clamp includes a pneumatic base and at least two sets of air passages disposed within the pneumatic base. The air passages are connected to an air shaft, and the air shaft is provided with a plurality of air blocks. When high-pressure gas is introduced into the air shaft, the air blocks push outward to clamp the drill bit.

[0009] Furthermore, the fixing component includes a fixing bracket and a driving leg and a clamping leg mounted on the fixing bracket. The head of the clamping leg is fixedly connected to a clamping block, and the driving leg is also rotatably connected to a limiting leg.

[0010] Furthermore, the frame body is also provided with a platform, and the platform has a contour groove, in which the part to be processed is placed.

[0011] Furthermore, the X-axis assembly includes an X-axis bracket and a first drive element and an X-axis slider disposed within the X-axis bracket, the X-axis slider being fixedly connected to the Y-axis assembly.

[0012] Furthermore, the Y-axis assembly includes a Y-axis bracket and a second drive element mounted on the Y-axis bracket. The second drive element is connected to a Y-axis slider, and the Y-axis slider is fixedly connected to a drilling assembly.

[0013] Furthermore, the first driving element, the second driving element, and the third driving element are motors.

[0014] The beneficial effects of this utility model are:

[0015] 1. Improve production efficiency: With the automatic descent function of the Y-axis, the operator only needs to place the powder metallurgy parts to be processed into the contour groove of the table, and after clamping with the fixing component, the machine will automatically complete the downward drilling, which greatly improves production efficiency.

[0016] 2. Automatic quick tool change: The drill bit assembly is equipped with an air passage and an air expansion shaft. By venting air, the drill bit can be quickly clamped and released. Combined with the cutter head holder placed on the machine frame, the required drill bit can be quickly changed.

[0017] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.
