Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a cutting equipment for processing general parts. Background Technology

[0002] In the field of general parts processing, the demand for cutting and processing round tubular components (such as automotive exhaust pipes and mechanical drive shafts) is increasing. Because these components have a circular cross-section, traditional cutting equipment faces two major technical challenges: first, the smooth surface of the tubing makes it difficult for conventional fixing structures to achieve stable positioning, easily leading to deviation during cutting; second, if metal debris and laser processing gases (such as ozone and metal vapor) generated during the cutting process are not collected in a timely manner, they will not only pollute the working environment but may also affect the health of operators.

[0003] According to the patent "A Cutting Equipment for Processing Automotive Parts" published in CN220761367U, the angle of the laser emitter is adjusted through the meshing transmission of gears and screws, solving the cutting requirements of inclined parts. However, this solution has obvious shortcomings in the processing of round tube parts. Metal shavings generated during cutting accumulate directly on the workbench surface, requiring frequent manual cleaning. Furthermore, no protective plates were designed for laser processing, posing a risk of laser reflection injury to operators during cutting. Additionally, the cutting gases were not filtered, failing to meet environmental and safety standards.

[0004] Therefore, we propose a cutting device for general parts processing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the direct accumulation of metal shavings on the workbench surface during cutting, requiring frequent manual cleaning, the lack of a protective plate for laser processing, the risk of laser reflection injury to operators during cutting, and the failure to filter the cutting gas, which does not meet environmental and safety standards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A general-purpose parts processing cutting device includes an operating table with an internal cavity and an opening at the center of the top, the front and back sides of which are also provided with slots; two fixed limiting mechanisms fixedly disposed on both sides of the top of the operating table for limiting the processing of cylindrical parts; a mobile laser cutting machine disposed between the two fixed limiting mechanisms for cutting the cylindrical parts fixed by the two fixed limiting mechanisms; and a collection structure disposed inside the cavity of the operating table for collecting debris and gas generated during cutting. A negative pressure recovery mechanism is located at the connection of the collection structure and consists of a drive unit, a connecting component, and a filter component. The filter component is connected to the drive unit, which is used to adsorb gas and generate negative pressure. The filter component is used to filter the adsorbed gas. The connecting component connects the negative pressure recovery mechanism to the collection structure and the operating table. A protective structure is located inside the operating table and is used to protect the mobile laser cutting machine during cutting.

[0007] As a preferred embodiment of this utility model, the fixed limiting mechanism includes: Two bottom inclined seats are symmetrically fixed on the top of the operating table for limiting the movement of round tube processing parts; The top mounting base has an opening facing downwards and beveled sides, and is used to fix the top of round tube-shaped machined parts; A fixing bracket is fixedly installed on the top of the operating table and located on the outside of the bottom inclined seat; The pneumatic rod is fixedly installed on the top of the fixed limiting mechanism, and its output end is connected to the top fixed seat to drive the top fixed seat to move up and down.

[0008] As a preferred embodiment of this utility model, the collecting structure includes: The waste recycling bin has openings on its top and right side walls for feeding waste and reserving installation positions, respectively, and has a storage cavity inside for storing waste. A sealing groove is provided on the front of the waste recycling bin; A door panel is located on the front of the waste recycling bin; A sealing plug is provided on the back side wall of the door panel and is used to be inserted into the sealing groove.

[0009] As a preferred embodiment of this utility model, the driving unit includes: Negative pressure pumps are used to create a negative pressure environment; A connecting pipe is installed in the waste recycling bin to connect the waste recycling bin to the negative pressure pump, thereby creating a negative pressure environment inside the waste recycling bin.

[0010] As a preferred embodiment of this utility model, the filtering component includes: An installation pipe is installed between the connecting pipe and the negative pressure pump to connect the negative pressure pump and the connecting pipe, so that the installation pipe, the connecting pipe and the negative pressure pump are connected in communication. Glass fiber filter, polytetrafluoroethylene filter, and activated carbon filter are arranged sequentially from left to right inside the installation tube to filter the gas passing through the installation tube.

[0011] As a preferred embodiment of this utility model, the connecting component includes: A connector, installed between the collection structure opening and the operating table opening, gradually narrows from top to bottom, and is used to collect exhaust gas and waste debris. A barrier net is installed on the inner wall of the storage cavity of the waste recycling bin to prevent waste from entering the connecting pipe.

[0012] As a preferred embodiment of this utility model, the protective structure includes: Two glass-based composite protective panels are installed in two slots on the workbench for protection during processing. Two connecting rods are respectively set at the bottom of both sides of the two glass-based composite protective panels; Two electric push rods are respectively located at the bottom of the two connecting rods, and are used to drive the connecting rods and the glass-based composite protective plate to perform lifting and lowering operations.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this utility model, the bottom inclined seat and the top fixed seat of the fixed limiting mechanism can form a limiting structure for clamping the round tube processing parts. The inclined surface of the bottom inclined seat fits the curved surface of the round tube, and the inclined side design of the top fixed seat can adapt to the top contour of round tubes of different diameters. Then, the top fixed seat is driven to move up and down by the pneumatic rod to achieve dual axial and circumferential fixation of the round tube.

[0014] The coordinated design of the collection structure and the negative pressure recovery mechanism can efficiently process the debris and gas generated during the cutting process. The waste debris collection box directly receives the cutting debris through the top opening. The negative pressure environment formed by the connecting pipe and the negative pressure pump can draw the debris and gas into the installation pipe. After multi-layer filtration by glass fiber filter, polytetrafluoroethylene filter and activated carbon filter, the metal particles and harmful gases (such as ozone) are purified in stages.

[0015] The glass-based composite protective plate of the protective structure is driven to rise and fall by an electric push rod. It can cover the slot of the operating table during cutting, blocking laser reflection and flying debris. The glass-based composite protective plate forms a composite protective layer by doping with metal oxides (such as cerium oxide and neodymium oxide) or by magnetron sputtering technology. It can achieve high OD value protection (OD7+) for specific wavelengths (such as 1064 nm and 532 nm), and can even resist ultraviolet lasers (such as 355 nm), avoiding laser damage to the operator's eyes. At the same time, the linkage design between the connecting rod and the electric push rod can flexibly adjust the protective height according to processing needs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Example like Figure 1-5 As shown, this utility model provides a technical solution: a cutting device for general parts processing, including an operating table 10, the operating table 10 having an internal cavity and an opening at the center of the top, with slots on the front and back sides of the opening; two fixed limiting mechanisms 40, fixedly arranged on both sides of the top of the operating table 10, for limiting the round tube-shaped processing parts; and a mobile laser cutting machine 50, arranged between the two fixed limiting mechanisms 40, for cutting the round tube-shaped processing parts fixed by the two fixed limiting mechanisms 40. The collecting structure 20 is located inside the receiving cavity of the operating table 10 and is used to collect debris and gas generated during cutting. The negative pressure recovery mechanism 60 is located at the connection of the collecting structure 20 and consists of a driving part, a connecting assembly, and a filtering assembly. The filtering assembly is connected to the driving part. The driving part is used to adsorb gas and generate negative pressure. The filtering assembly is used to filter the adsorbed gas. The connecting assembly connects the negative pressure recovery mechanism 60 to the collecting structure 20 and the operating table 10. The protective structure 30 is located inside the operating table 10 and is used to provide protection when the mobile laser cutting machine 50 is cutting.

[0023] After the cylindrical processing parts are placed between two fixed limiting mechanisms 40 and clamped, the mobile laser cutting machine 50 moves along the guide rail to the cutting position. The material is melted or vaporized by a high-energy laser beam to complete the cutting. The debris and gas generated during the cutting process fall into the collection structure 20 below through the top opening of the operating table 10. At the same time, the negative pressure generated by the negative pressure recovery mechanism 60 draws the debris and gas into the filter assembly for purification. The protective structure 30 rises during cutting to block laser reflection and spatter, protecting the safety of the operator.

[0024] The fixed limit mechanism 40 includes: Two bottom inclined seats 401 are symmetrically fixed on the top of the operating table 10 for limiting the movement of round tube processing parts; The top fixing seat 402 has an opening facing downwards and beveled sides, and is used to fix the top of the round tube-shaped machined parts; The mounting bracket 403 is fixedly installed on the top of the operating table 10 and located on the outside of the bottom inclined seat 401; The pneumatic rod 404 is fixedly installed on the top of the fixed limiting mechanism 40, and its output end is connected to the top fixed seat 402 to drive the top fixed seat 402 to move up and down.

[0025] When a cylindrical part is placed between two bottom inclined seats 401, the inclined surface of the bottom inclined seat 401 fits against the outer surface of the cylindrical part, providing initial support. The air rod 404 drives the top fixed seat 402 to move downward, and its two inclined sides contact the top of the cylindrical part and apply pressure, forming a four-point support structure with two points at the bottom and two points at the top. This structure evenly distributes pressure through four-point contact, effectively limiting the axial displacement and circumferential rotation of the cylindrical part, and ensuring the stability of the part during the cutting process.

[0026] Collection structure 20 includes: The waste recycling bin 201 has openings on its top and right side walls for feeding waste and reserving installation positions, respectively, and has a storage cavity inside for storing waste. A sealing groove 202 is provided on the front of the waste recycling bin 201; Door panel 203 is located on the front of waste recycling bin 201; The sealing plug-in block 204 is set on the back side wall of the door panel 203 and is used to be inserted into the sealing groove 202.

[0027] The cutting debris and gas fall into the storage chamber of the waste recycling bin 201 through the opening at the top of the operating table 10. The negative pressure recycling mechanism 60 forms an airflow channel through the opening on the right side wall to suck out the gas and fine particles. When it is necessary to clean the waste, the door panel 203 is pulled outward to disengage the sealing plug 204 from the sealing groove 202, and the storage chamber can be opened for cleaning. The sealing structure ensures that there is no leakage during operation.

[0028] The drive unit includes: Negative pressure pump 608 is used to generate a negative pressure environment; The connecting pipe 603 is installed in the waste recycling bin 201 to connect the waste recycling bin 201 and the negative pressure pump 608, thereby creating a negative pressure environment inside the waste recycling bin 201.

[0029] After the negative pressure pump 608 is started, it draws air from the waste recycling box 201 through the connecting pipe 603, creating a negative pressure inside the box. Under the action of the pressure difference, the debris and gas at the top opening of the operating table 10 are sucked into the waste recycling box 201. Larger particles settle at the bottom of the storage chamber due to gravity, while the gas enters the filter assembly through the connecting pipe 603 for processing.

[0030] The filtering components include: The mounting pipe 604 is disposed between the connecting pipe 603 and the negative pressure pump 608, and is used to connect the negative pressure pump 608 and the connecting pipe 603, so that the mounting pipe 604, the connecting pipe 603 and the negative pressure pump 608 are connected. Glass fiber filter element 605, polytetrafluoroethylene filter element 606 and activated carbon filter element 607 are arranged sequentially from left to right inside the mounting tube 604 to filter the gas passing through the mounting tube 604.

[0031] After the airflow containing debris and gas enters the installation pipe 604 through the connecting pipe 603, it first passes through the glass fiber filter element 605, whose fine fiber structure intercepts larger particles such as metal debris; then, the polytetrafluoroethylene filter element 606 further filters submicron particles and some aerosols; finally, the activated carbon filter element 607 removes odors, organic pollutants and harmful gases such as ozone from the gas through adsorption, and the purified air is discharged through the negative pressure pump 608.

[0032] The connection components include: A connector 601 is installed between the opening of the collection structure 20 and the opening of the operating table 10. It gradually narrows from top to bottom and is used to collect exhaust gas and waste debris. A barrier net 602 is installed on the inner wall of the storage cavity of the waste recycling bin 201 to prevent waste from entering the connecting pipe 603.

[0033] The narrowing structure of connector 601 creates a Venturi effect, accelerating the flow speed of exhaust gas and debris, allowing them to enter the collection structure 20 more efficiently. The barrier mesh 602 is made of fine metal mesh or porous material, allowing gas to pass through while blocking larger debris particles, preventing them from entering the connecting pipe 603 and causing pipe blockage or damage to the negative pressure pump 608.

[0034] The protective structure 30 includes: Two glass-based composite protective panels 301 are installed in two slots of the operating table 10 respectively for protection during processing; Two connecting rods 302 are respectively set at the bottom of both sides of the two glass-based composite protective plates 301; Two electric push rods 303 are respectively installed at the bottom of the two connecting rods 302, and are used to drive the connecting rods 302 and the glass-based composite protective plate 301 to perform lifting and lowering operations.

[0035] Before the cutting operation begins, the electric push rod 303 pushes the glass-based composite protective plate 301 up through the connecting rod 302 until it completely covers the slot of the operating table 10. The metal oxide coating in the glass-based composite protective plate 301 absorbs or reflects lasers of specific wavelengths, such as 1064nm. Its high light transmittance ≥70% ensures that the operator can clearly observe the cutting process. When the cutting is completed or the workpiece needs to be replaced, the electric push rod 303 drives the protective plate down to expose the slot for operation.

[0036] Summary of the overall working principle of the equipment 1. Fixed limit mechanism 40 working process Initial state: The gas spring 404 is in the retracted state, and the distance between the top fixed seat 402 and the bottom inclined seat 401 is at its maximum.

[0037] Loading and positioning: Round tube parts are placed on the inclined surfaces of two bottom sloping seats 401 to form two-point support.

[0038] Clamping process: The air rod 404 extends, driving the top fixed seat 402 to descend. Its two inclined sides contact the top of the round tube, forming two additional support points. Finally, the axial and circumferential limits of the round tube are achieved through four-point contact between the bottom two points and the top two points, preventing displacement or rotation during cutting.

[0039] 2. Cutting Operation Process Laser cutting: The mobile laser cutting machine 50 moves along the guide rail to the preset cutting position, and the high-energy laser beam is focused on the surface of the round tube to complete the cutting by melting or vaporizing the material.

[0040] Synchronous protection: Before cutting, the electric push rod 303 drives the glass-based composite protective plate 301 to rise, covering the slot of the operating table 10 to block laser reflection and flying debris.

[0041] 3. Debris and Gas Handling Process Negative pressure adsorption: When the negative pressure pump 608 is started, a negative pressure is formed in the waste recycling box 201 through the connecting pipe 603. The debris and gas generated by cutting are accelerated by the connecting part 601 and then enter the collection structure 20.

[0042] Three-stage filtration: Barrier mesh 602: Intercepts larger particles to prevent them from entering the pipes; Glass fiber filter element 605: filters metal debris in the millimeter range; PTFE filter element 606 + activated carbon filter element 607: respectively filter submicron particles and gaseous pollutants such as ozone and metal vapor.

[0043] Purified exhaust: The treated clean air is discharged from the equipment through negative pressure pump 608.

[0044] Waste removal: Turn off the negative pressure pump 608, open the door panel 203, and remove the waste from the storage chamber.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
