Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, and more specifically, to a dust-proof device for machining machine tool accessories. Background Technique

[0002] A machine tool is a machine for manufacturing machines and machinery, also known as a mother machine or a tool machine. It plays a significant role in the construction of national economic modernization and is an indispensable equipment in the manufacturing industry. Machine tools are widely used in the manufacturing industry and are suitable for the processing of various metal materials.

[0003] During the process of machining metal materials by a machine tool, a large amount of dust and debris are easily generated. Therefore, it is necessary to set up dust-proof and dust-removing equipment to purify the processing environment. The existing dust-proof equipment generally directly removes dust through a dust-removing mechanism, sucks dust from the processing area through a dedicated dust suction channel, and plays a dust-proof effect. However, the single dust suction type has low dust-removing efficiency. It has a good cleaning effect on the dust scattered in the air, but the dust removal effect on the dust adhering to the surface of metal materials is poor. In view of this, we propose a dust-proof device for machining machine tool accessories. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a dust-proof device for machining machine tool accessories to solve the technical problem of poor dust removal effect of the current single adsorption type dust removal device.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A dust-proof device for machining machine tool accessories, including a lifting table, a front box, a rear box and a dust collection pipe. The lifting table is slidably installed at the front end of the column of the machine tool. A bottom pocket is provided on the lower end surface of the lifting table. A material placing table is fixed in the middle of the upper end surface of the lifting table. The rear box is snap-fitted and installed at the rear end of the upper end surface of the lifting table. An adapter slot is provided on the front end surface of the rear box. The dust collection pipe is installed through the upper side inside the adapter slot. The front box is fixed at the front end of the upper end surface of the lifting table. Exhaust windows are provided at both ends inside the front box. A voltage conversion box is fixed in the middle inside the front box. An electric telescopic rod is provided at the upper end of the voltage conversion box. A piston sheet is slidably installed on the upper side inside the voltage conversion box, and the lower end of the electric telescopic rod is connected to the piston sheet. A gas supply pipe is installed through the lower end of the voltage conversion box, and the lower end of the gas supply pipe communicates with the inside of the bottom pocket.

[0006] When the utility model is in use, the metal fittings are placed on the material placing table. When a large amount of dust and debris are generated during the hole opening process by the drill bit, the dust removal fan and the exhaust pump inside the bottom pocket are started during the processing. The exhaust pump injects air into the pressure conversion box through the air supply pipe, and then the air flow is discharged from the exhaust window to the processing area through the circulation pipe, blowing the dust to the rear box. The negative pressure generated by the dust removal fan adsorbs. The dust collection pipe is connected to the processing area. The air flow blown to the rear box is gathered by the poly sail and then discharged to the dust removal fan and the dust removal filtering mechanism in the bottom pocket through the dust collection pipe and the conduit. Through the above spraying and adsorption, the dust prevention and cleaning of the processing area are completed. The spraying method makes the metal debris and dust attached to the surface of the workpiece rise, and then the dust removal is completed through adsorption, ensuring the quality of dust prevention and removal. When the air flow enters the pressure conversion box, the passage of the circulation pipe is closed by closing the solenoid valve, and then the air flow is continuously injected to increase the internal air pressure. When the preset value is reached, the passage of the circulation pipe of the solenoid valve is opened, so that the high-pressure air flow is discharged outward through the exhaust window. During the exhaust process, the electric telescopic rod can be started to drive the piston piece to descend to maintain the stable air pressure of the outward sprayed air flow. The intermittent spraying method can be adopted to increase the air pressure of each spray, ensuring the dust removal quality while preventing large-sized metal debris from contaminating the surface of the metal workpiece and affecting the processing quality.

[0007] Preferably, a sliding sleeve is fixed to the rear end face of the lifting table, and the sliding sleeve is slidably clamped to the front end of the column of the machine tool. The lifting table is slidably installed on the column of the machine tool through the sliding sleeve to maintain the lifting stability of the lifting table.

[0008] Preferably, conduits are installed through both sides of the rear end of the lifting table, and the lower ends of the conduits communicate with the inside of the bottom pocket. The lower ends of the conduits are connected to the air inlets of the dust removal fan inside the bottom pocket.

[0009] Preferably, docking ports are opened on the lower sides of both ends of the rear box, and the upper ends of the conduits are inserted into the corresponding docking ports. The docking ports are connected to the upper ends of the conduits, so that the negative pressure adsorption force of the dust removal fan is transmitted to the inside of the rear box.

[0010] Preferably, the lower side of the adapter slot is docked with the rear end of the material placing table, and a poly sail is provided on the upper side of the adapter slot. The adapter slot is clamped and fitted to the material placing table to make the dust removal area correspond to the processing area.

[0011] Preferably, the poly sail is designed in an arc shape, and the poly sail corresponds to the exhaust window of the front box. The front end of the dust collection pipe penetrates and connects to the center of the poly sail. The poly sail designed in an arc shape makes the sprayed air flow gather after passing through the arc surface of the poly sail and then concentrate on the dust collection pipe.

[0012] Preferably, circulation pipes are installed through both sides of the inner bottom end of the pressure conversion box, and the circulation pipes communicate with the exhaust window of the front box. A solenoid valve is provided at the front end of the circulation pipe. The opening and closing of the passage of the circulation pipe can be completed through the solenoid valve, and the circulation pipe guides the air flow to be discharged outward through the exhaust window.

[0013] Preferably, the outer side of the piston piece is wrapped with a sealing sleeve, and the sealing sleeve fits the inner wall of the transformer box, enhancing the connection tightness between the piston piece and the inner wall of the transformer box through the sealing sleeve.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By designing the front box and the rear box, the metal fittings are placed on the material placing table. When dust debris is generated during hole opening, the dust removal fan and the exhaust pump inside the bottom pocket are started. The exhaust pump injects air into the transformer box through the air supply pipe, and then the air flow is discharged from the exhaust window to the processing area through the flow pipe, blowing the dust towards the rear box. The negative pressure generated by the dust removal fan adsorbs. The air flow blown towards the rear box is gathered by the gathering sail and then discharged to the dust removal fan and the dust removal filtering mechanism in the bottom pocket through the dust collection pipe and the conduit. Through the above spraying and adsorption, the dust prevention and cleaning of the processing area are completed. The spraying makes the metal debris and dust attached to the surface of the workpiece rise, and then the dust removal is completed through adsorption, ensuring the quality of dust prevention and removal.

[0016] 2. The present utility model also designs the transformer box. When the air flow enters the transformer box, the passage of the flow pipe is closed by closing the solenoid valve, and then the air flow is continuously injected to increase the internal air pressure. When the preset value is reached, the passage of the flow pipe of the solenoid valve is opened, so that the high-pressure air flow is discharged outwards through the exhaust window. During the exhaust process, the electric telescopic rod can be started to drive the piston piece to descend to maintain the air pressure stability of the outwardly sprayed air flow. Through the intermittent spraying method, the air pressure of a single spray can be increased, ensuring the dust removal quality and preventing large-sized metal debris from contaminating the surface of the metal workpiece and affecting the processing quality.
