Description

Technical Field

[0001] This invention relates to the field of conventional lathe technology, and more specifically, to a multifunctional protective structure for conventional lathes. Background Technology

[0002] A general-purpose lathe is a horizontal lathe capable of machining various types of workpieces such as shafts, discs, and rings using multiple processes. It is commonly used to machine the internal and external rotating surfaces, end faces, and various internal and external threads of workpieces. With appropriate cutting tools and accessories, it can also perform drilling, reaming, tapping, and knurling. The general-purpose lathe is the most widely used type of lathe.

[0003] The State Intellectual Property Office has published an invention patent application with application number CN02267618X entitled "A Novel Ordinary Lathe." This novel ordinary lathe solves the problems of existing ordinary lathes, such as low spindle speed, inconvenient gear shifting, limited selectable spindle gears, and inability to achieve optimal cutting speed. It includes a spindle, a spindle drive motor, a transparent optical disc on the spindle, and a photoelectric switch located at a position corresponding to the transparent optical disc. The photoelectric switch is connected to a spindle speed display controller. The spindle drive motor is a variable frequency motor and is connected to a variable frequency speed controller. The spindle speed display controller consists of a programmable controller and a display device.

[0004] Currently, in the actual use of ordinary lathes, a large amount of debris is inevitably generated during machining, and this debris will fly everywhere. The aforementioned patent does not have a protective structure to block the flying debris from ordinary lathes. The flying debris can easily injure people at close range, and there is a technical problem that it cannot effectively block and protect against the debris. Therefore, this invention proposes a multi-functional protective structure for ordinary lathes. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional protective structure for ordinary lathes, which solves the technical problem of how to block and protect against chips when machining workpieces on ordinary machine tools, and has multifunctional technical effects.

[0006] A multifunctional protective structure for a conventional lathe includes a lathe body and a protective cover mounted on the lathe body. A sealed protective door is hinged to an opening on one side of the protective cover. An observation window is provided on the sealed protective door. An electric cylinder, a fan, and a collection box are installed on the inner side of the sealed protective door. A scraper is bolted to the output end of the electric cylinder. The scraper is equipped with a bristle brush, and the outer surface of the bristle brush abuts against the observation window and the sealed protective door, respectively.

[0007] The top of the collection box is connected to a material discharge chute, the input end of the blower is connected to the collection box, and the inside of the collection box is equipped with multiple filter screens, all of which are located between the input end of the blower and the material discharge chute.

[0008] The material discharge trough plate is provided with an inclined surface, and the bottom end of the inclined surface is provided with a connecting part, which is connected to the collection box.

[0009] The top of the collection box is inclined with a material discharge chute plate, and the side of the material discharge chute plate is set on the upper end surface of the collection box through a hinge seat;

[0010] One end of the material discharge trough is connected to the arc-shaped material discharge cylinder, the bottom end of the material discharge cylinder is connected to the collection box, and the other end is provided with an arc-shaped rod. The arc-shaped rod is movably embedded in the arc-shaped cylinder, and a spring is provided in the arc-shaped cylinder. The bottom end of the arc-shaped rod is connected to the spring, and the bottom end of the arc-shaped cylinder is provided on the support base.

[0011] The center of the arc of the material discharge cylinder, the arc rod, and the arc cylinder is located at the rotation center of the hinge seat;

[0012] The input end of the blower is connected to the collection box, and the inside of the collection box is equipped with multiple filter screens, all of which are located between the input end of the blower and the discharge chute plate.

[0013] An auxiliary sliding rod is installed on the inner side of the sealed protective door. The outer surface of the auxiliary sliding rod slides through the inside of the scraper, and the auxiliary sliding rod is located between the observation window and the material discharge chute.

[0014] The bottom of one side of the collection box is connected to a drain pipe, and an electric valve is installed on the drain pipe.

[0015] The collection box is equipped with an inclined plate inside, and both the inclined plate and the pipe are located on the side of the filter screen away from the input end of the fan.

[0016] The outer side of the sealed protective door is provided with a handle groove.

[0017] A sliding door is slidably provided on the protective cover on the opposite side of the sealed protective door. A limit block is provided on the upper surface of the protective cover. The limit block is connected to the sliding door through a limit rod. The limit rod is detachably connected to the side of the scraper.

[0018] The limiting rod includes a connecting rod, and two vertical columns, one vertically arranged at both ends of the connecting rod. The first vertical column is detachably connected to the limiting block, and the second vertical column passes horizontally through the sliding door and is detachably connected to the scraper.

[0019] The technical effects and advantages of this invention are as follows:

[0020] (1) Compared with the prior art, the protective cover, observation window and closed sealed protective door can block the debris generated during the processing of ordinary lathe, prevent the debris from flying to the outside of ordinary lathe and injuring the workers and other equipment around it, so as to better protect the workers and other equipment around it, and improve the protective effect and relative safety of ordinary lathe.

[0021] The electric cylinder, scraper, and brush can clean the debris and dirt that adheres to the observation window due to the blockage of debris. The fan, collection box, discharge chute, and filter screen can also collect the debris cleaned from the protective cover and the observation window. It has multiple functions and is easy to use.

[0022] (2) This solution incorporates an electric cylinder, which offers the following technical advantages:

[0023] First, the electric cylinder is combined with the material discharge chute. Under the action of the electric cylinder, the scraper moves back and forth. Since the material discharge chute is set at an angle, the bottom of the scraper will gradually contact one end of the material discharge chute and press it down. The spring in the arc-shaped cylinder is compressed. When the scraper returns to its original position, the material discharge chute rises. This makes the material discharge chute move up and down in an arc shape, which promotes the vibration of the material discharge chute and makes the metal chips enter the material discharge cylinder more smoothly, thus completing the collection of metal chips. The design concept is ingenious.

[0024] Secondly, the electric cylinder is combined with the limit rod. When the sliding door needs to be opened, the second vertical column is inserted into the side of the scraper. Driven by the scraper, the sliding door moves. When the sliding door needs to be closed during processing, the second vertical column is separated from the scraper, and the first vertical column is embedded in the limit block. This realizes the automation of the opening and closing of the sliding door and saves manpower. Attached Figure Description

Detailed Implementation

[0033] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0034] Example 1

[0035] See Figures 1-3 , Figure 6 , Figure 7 A multi-functional protective structure for a common lathe includes a lathe body 1 and a protective cover 2 installed on the lathe body 1. A sealed protective door 3 is hinged to an opening on one side of the protective cover 2. An observation window 4 is provided on the sealed protective door 3. An electric cylinder 5, a fan 6 and a collection box 7 are installed on the inner side of the sealed protective door 3. A scraper 8 is installed on the output end of the electric cylinder 5 by bolts. A fluff brush 9 is provided on the scraper 8, and the outer surface of the fluff brush 9 abuts against the observation window 4 and the sealed protective door 3 respectively.

[0036] The top of the collection box 7 is connected to the discharge chute 10, the input end of the blower 6 is connected to the collection box 7, and the inside of the collection box 7 is provided with multiple filter screens 11, and the multiple filter screens 11 are all located between the input end of the blower 6 and the discharge chute 10.

[0037] The material discharge chute has an inclined surface, and the bottom end of the inclined surface has a connecting part, which is connected to the collection box 7.

[0038] An auxiliary slide rod 12 is installed on the inner side of the sealed protective door 3. The outer surface of the auxiliary slide rod 12 slides through the inside of the scraper 8, and the auxiliary slide rod 12 is located between the observation window 4 and the material discharge chute 10.

[0039] A drain pipe 13 is connected to one side of the bottom of the collection box 7, and an electric valve is installed on the drain pipe 13.

[0040] The collection box 7 is equipped with an inclined plate 14, and both the inclined plate 14 and the pipe 13 are located on the side of the filter screen 11 away from the input end of the fan 6.

[0041] A handle groove 15 is provided on the outside of the sealed protective door 3.

[0042] A sliding door 23 is slidably provided on the other side of the protective cover 2 opposite to the sealed protective door 3. A limit block 21 is provided on the upper end surface of the protective cover 2. The limit block 21 is connected to the sliding door 23 through a limit rod 22. The limit rod 22 is detachably connected to the side of the scraper 8.

[0043] The purpose of this design is to facilitate installation and disassembly, and to enable extensive manual operation when a conventional lathe needs repair, making it convenient and quick.

[0044] The limiting rod 22 includes a connecting rod 221 and two vertical columns 222 and 223 respectively vertically arranged at both ends of the connecting rod 221. The vertical column 222 is detachably connected to the limiting block 21, and the vertical column 223 passes horizontally through the sliding door 23 and is detachably connected to the scraper 8.

[0045] An arc-shaped groove is provided on the limiting block 21, and the first vertical column 222 is embedded in the arc-shaped groove. The center of the arc-shaped groove is at the center of the second vertical column 223. When the second vertical column 223 rotates, it can drive the first vertical column 222 to move in the arc-shaped groove, realizing the process of connecting and separating the first vertical column 222 from the limiting block 21.

[0046] The specific working process of this invention:

[0047] By opening the sealed protective door 3, the workpiece to be processed can be placed on the lathe body 1 as needed, and then the sealed protective door 3 can be closed. The protective cover 2, observation window 4 and closed sealed protective door 3 of this protective structure can block the debris generated during the processing of the ordinary lathe, preventing the debris from flying to the outside of the ordinary lathe and injuring the workers and other surrounding equipment. It avoids the impact of debris on the workers' bodies and does not easily pollute the working environment outside the ordinary lathe, thus providing better protection for the workers and other surrounding equipment, improving the protective effect and relative safety of the ordinary lathe.

[0048] The electric cylinder 5 drives the scraper 8 and the brush 9 to reciprocate linearly, cleaning and removing dust, debris and other dirt adhering to the inside of the observation window 4 and the side near the lathe body 1, keeping the observation window 4 clean and allowing staff to observe the relevant situation inside the protective cover 2 without manual cleaning, reducing labor intensity, saving time and effort. Moreover, its protective structure has multiple functions, improving the efficiency of ordinary lathe operation. While the electric cylinder 5 drives the scraper 8 to move, the scraper 8 also slides and rubs on the auxiliary slide rod 12. The auxiliary slide rod 12 can provide a certain degree of auxiliary support and stability for the scraper 8. The observation window 4 is an existing transparent tempered glass window, which is convenient for personnel to observe the internal processing of ordinary lathe. This application will not elaborate further.

[0049] The top of the collection box 7 is connected to the discharge chute plate 10. The input end of the blower 6 is connected to the collection box 7. The collection box 7 is equipped with multiple filter screens 11, and the multiple filter screens 11 are located between the input end of the blower 6 and the discharge chute plate 10. The bottom side of the collection box 7 is connected to the drain pipe 13, and the drain pipe 13 is equipped with an electric valve. The collection box 7 is equipped with an inclined plate 14, and the inclined plate 14 and the drain pipe 13 are located on the side of the filter screens 11 away from the input end of the blower 6.

[0050] While the electric cylinder 5 drives the scraper 8 to move, the blower 6 and the discharge chute 10 can, as needed, suck and carry away the debris cleaned by the scraper 8 and the brush 9, as well as the debris in the protective cover 2, and transport them to the collection box 7. Multiple filters 11 can filter and separate the air carrying debris entering the collection box 7, intercepting and retaining the debris in the collection box 7. The air filtered by the filters 11 is discharged from the collection box 7 under the continued action of the blower 6. The blower 6, the collection box 7 and the filters 11 of this protective structure can also effectively collect the debris cleaned from the protective cover 2 and the observation window 4. It has multiple functions and is easy to use. The existing electric valve can be used to open the drain pipe 13 to discharge the debris in the collection box 7.

[0051] Example 2

[0052] See Figure 1 , Figures 5-7 The top of the collection box 7 is inclined with a material discharge chute 10, and the side of the material discharge chute is set on the upper surface of the collection box 7 through a hinge seat 73.

[0053] One end of the material discharge chute 7 is connected to the arc-shaped material discharge cylinder 72, the bottom end of the material discharge cylinder 72 is connected to the collection box 7, and the other end is provided with an arc-shaped rod 74. The arc-shaped rod 74 is movably embedded in the arc-shaped cylinder 75. A spring is provided in the arc-shaped cylinder 75, the bottom end of the arc-shaped rod 74 is connected to the spring, and the bottom end of the arc-shaped cylinder 75 is provided on the support base 76.

[0054] The arc centers of the material discharge cylinder 72, the arc rod 74, and the arc cylinder 75 are set at the rotation center of the hinge seat 73;

[0055] The input end of the blower 6 is connected to the collection box 7. The collection box 7 is equipped with multiple filter screens 11, and the multiple filter screens 11 are located between the input end of the blower 6 and the discharge chute 10.

[0056] In actual operation, under the action of electric cylinder 5, scraper 8 moves back and forth. Since the discharge trough 10 is inclined, the bottom end of scraper 8 will gradually contact one end of discharge trough 10 and press it down. The spring in arc cylinder 75 is compressed. When scraper 8 returns to its original position, discharge trough 10 rises. This makes discharge trough 10 realize the arc motion of up and down, which promotes the vibration of discharge trough 10. The vibration process promotes the metal chips to enter the discharge cylinder 72 more smoothly, thus completing the collection of metal chips.

[0057] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
