Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of machine tool fixture auxiliary devices, specifically referring to an air blowing auxiliary structure for a sinusoidal magnetic table used in thread rolling. Background Technology
[0002] Sine magnetic tables are precision fixtures commonly used in grinding machines. They can be used for precision grinding of inclined surfaces of workpieces such as thread rolling dies and die tops. By adjusting the tilt angle, they provide a precise machining reference for the workpiece to ensure the machining accuracy of key features such as the thread rolling die tooth profile.
[0003] However, during the machining process, existing sinusoidal magnetic stages are prone to leaving coolant and iron filings on the contact surface between their fixed base and the machine tool table. The liquid adsorption force formed by the coolant increases the resistance to removing, disassembling, and moving the magnetic stage, affecting machining efficiency and easily damaging the stage's precision due to forced prying. Furthermore, existing sinusoidal magnetic stages lack a dedicated air-blowing cleaning structure for their fixed base, making it impossible to actively remove impurities from the contact surface using airflow; manual wiping is the only option, resulting in poor cleaning effectiveness and cumbersome operation. Therefore, there is an urgent need for an air-blowing auxiliary structure that can efficiently remove coolant and iron filings from the contact surface and facilitate easy removal and disassembly of the sinusoidal magnetic stage. Utility Model Content
[0004] This utility model provides an air-blowing auxiliary structure for a sinusoidal magnetic table used in thread rolling, which aims to solve the problems mentioned in the background art by blowing air onto the mating surface through an air inlet located on the side wall of the fixed base, a main flow channel and multiple branch flow channels that are interconnected internally, and multiple air outlets that penetrate the bottom surface.
[0005] The purpose of this utility model is achieved as follows: an air-blowing auxiliary structure for a sinusoidal magnetic table used in thread rolling is integrated on a fixed base of the sinusoidal magnetic table, comprising: An air inlet is located on the side wall of the fixed base; An airflow channel is located inside the fixed base and includes a main flow channel and multiple branch flow channels that are interconnected. One end of the main flow channel is connected to the air inlet, one end of each branch flow channel is connected to the main flow channel, and the other end of each branch flow channel penetrates the bottom surface of the fixed base to form multiple air outlets.
[0006] The present invention is further configured such that each of the branch channels includes a horizontal extension section and a vertical extension section, the upper end of the vertical extension section is connected to the horizontal extension section, and the lower end of the vertical extension section forms the air outlet.
[0007] The present invention is further configured such that the inner diameter of the airflow channel gradually decreases along the direction from the main flow channel to the branch flow channel.
[0008] The present invention is further configured to include a buffer groove provided on the bottom surface of the fixed base, the buffer groove being opened on the outer periphery of each of the air outlets and communicating with the air outlets.
[0009] The present invention is further configured such that the buffer groove is an annular groove coaxially arranged with the corresponding air outlet.
[0010] The present invention is further configured to include a guide groove disposed on the bottom surface of the fixed base, the guide groove being connected to the air outlet.
[0011] The present invention is further configured such that the guide channel is composed of crisscrossing channels, covering the entire bottom surface of the fixed base, and each channel is connected to the air outlet and extends to the edge of the bottom surface of the fixed base.
[0012] By adopting the above technical solution, the beneficial effects that this utility model can achieve are: 1. By coordinating the air inlet, main flow channel and multi-branch flow channel, the airflow is evenly distributed to each air outlet on the bottom surface of the fixed base, realizing full-area air blowing on the contact surface, which improves the cleaning coverage of coolant and iron filings.
[0013] 2. The airflow channel features a gradually narrowing diameter design, which allows the airflow to be naturally pressurized during transmission before being ejected from the outlet, thus improving the removal of residual impurities from the bonding surface.
[0014] 3. The airflow is buffered by the buffer groove and guided by the crisscrossing guide grooves, allowing the airflow to spread evenly and impurities to be discharged quickly, thus improving the overall efficiency of air blowing cleaning. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figures 1-3 : Example 1:
[0018] This embodiment provides an air-blowing auxiliary structure for a sinusoidal magnetic table used in thread rolling, integrated on a fixed base 2 of the sinusoidal magnetic table 1, including: Air inlet 3 is located on the side wall of the fixed base 2; The airflow channel 4 is located inside the fixed base 2. It includes a main flow channel 40 and multiple branch flow channels 41 that are interconnected. One end of the main flow channel 40 is connected to the air inlet 3, one end of each branch flow channel 41 is connected to the main flow channel 40, and the other end of each branch flow channel 41 penetrates the bottom surface of the fixed base 2 to form multiple air outlets 5.
[0019] The fixed base 2 is a rectangular block component made of magnetically conductive metal material. This magnetic conductivity is compatible with the sinusoidal magnetic table 1, ensuring that the fixed base 2 can be attracted and positioned by the machine tool's magnetic worktable without affecting the original magnetic clamping function of the sinusoidal magnetic table 1. An airflow channel 4 is integrally formed inside the fixed base 2. An air inlet 3 is opened on the side wall, and multiple air outlets 5 are opened on the bottom surface. The air inlet 3 is a circular through hole used to connect to an external compressed air pipeline and is compatible with the connector of the external compressed air pipeline. The airflow channel 4 consists of a main flow channel 40 and multiple branch flow channels 41 that are interconnected. The main flow channel 40 is a straight circular hole that extends horizontally inward along the length of the fixed base 2 from the air inlet 3 on the side wall. One end of each branch flow channel 41 connects to the end of the main flow channel 40, and the other end penetrates the bottom surface of the fixed base 2, forming an air outlet 5. The branch channels 41 are symmetrically distributed along the end of the main channel 40, and their number corresponds one-to-one with the number of air outlets 5. The symmetrical distribution ensures that the airflow is evenly delivered to different positions on the bottom surface of the fixed base 2. The connection between the branch channels 41 and the main channel 40 is made with a rounded transition to reduce airflow resistance.
[0020] Each branch channel 41 includes a horizontal extension section 410 and a vertical extension section 411. The horizontal extension section 410 extends horizontally into the fixed base 2 from its connection with the main channel 40. The upper end of the vertical extension section 411 connects to the end of the horizontal extension section 410, and the lower end of the vertical extension section 411 penetrates the bottom surface of the fixed base 2, forming an air outlet 5. The connection between the horizontal extension section 410 and the vertical extension section 411 is a rounded transition. The airflow is guided from the main channel 40 to the corresponding position of the air outlet 5 through the horizontal extension section 410, and then the airflow is vertically guided to the bottom surface of the fixed base 2 through the vertical extension section 411, so that the airflow direction of the air outlet 5 is perpendicular to the contact surface.
[0021] The airflow channel 4 adopts a gradually decreasing inner diameter structure. The main flow channel 40 has the largest inner diameter, the horizontal extension section 410 of the branch flow channel 41 has a smaller inner diameter than the main flow channel 40, and the vertical extension section 411 has a smaller inner diameter than the horizontal extension section 410. After compressed air enters from the inlet 3, it flows sequentially through the main flow channel 40, the horizontal extension section 410, and the vertical extension section 411. As the inner diameter of the channel gradually decreases, the airflow pressure increases step by step, and finally, when it is ejected from the outlet 5, it forms a high-speed airflow with strong impact force.
[0022] A buffer groove 6 is provided on the bottom surface of the fixed base 2. The buffer groove 6 is a circular concave step, which is formed on the outer periphery of each air outlet 5, coaxially arranged with the air outlet 5, and connected to the air outlet 5. The diameter of the buffer groove 6 is larger than the diameter of the air outlet 5, and the depth of the groove is smaller than the length of the air outlet 5. The high-pressure airflow ejected from the air outlet 5 first enters the buffer groove 6, and completes buffering and diffusion within the groove space to form a uniform airflow layer before spreading outward, avoiding concentrated airflow impact that could cause incomplete local purging.
[0023] The bottom surface of the fixed base 2 is also provided with a guide channel 7. The guide channel 7 is connected to the air outlet 5 and is used to guide the airflow and blown-out material to be discharged in a preset direction. The guide channel 7 is composed of multiple horizontal and vertical channels 70, which form a grid-like layout on the bottom surface of the fixed base 2, covering the entire bottom surface area. One end of each channel 70 is connected to the buffer groove 6, and the other end extends to the edge of the bottom surface of the fixed base 2. After diffusion, the airflow in the buffer groove 6 flows towards the bottom edge along the guide channel 7 connected to it, while carrying the blown-out coolant and iron filings out of the contact area.
[0024] The working principle of this utility model is as follows: When it is necessary to remove or detach the sinusoidal magnetic table 1, the magnetic attraction of the machine tool table is turned off, and the external compressed air pipeline is connected to the air inlet 3 on the side wall of the fixed base 2 and compressed air is introduced. The compressed air enters the main channel 40 through the air inlet 3, and is transmitted along the main channel 40 to the horizontal extension section 410 of the branch channel 41, and then flows to the air outlet 5 through the vertical extension section 411. During the flow process, the air pressure increases step by step as the inner diameter of the airflow channel 4 gradually decreases. After the high-pressure airflow is ejected from the air outlet 5, it first enters the buffer groove 6 for buffer diffusion, forming a uniform airflow layer, and then diffuses along the guide groove 7 connected to the buffer groove 6 to the entire bottom surface of the fixed base 2, blowing the coolant and iron filings at the contact surface away from the bottom edge along the guide groove 7. After the coolant and iron filings at the contact surface are completely blown away, the additional adsorption force between the contact surfaces disappears, and the operator can easily remove or move the sinusoidal magnetic table 1 from the machine tool table.
[0025] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
