Description

Technical Field

[0001] This utility model relates to the field of lathe technology, and in particular to a gear machining lathe. Background Technology

[0002] Gears are typically machined using a lathe, where a cutting tool is used to cut the gear blank to form the gear product.

[0003] When a cutting tool cuts a gear blank, it generates a large amount of waste chips. The traditional way to deal with waste chips is to use an air gun to blow the lathe after the gear is machined, so that the waste chips are blown down to the bottom of the lathe and then swept away. Often, a certain amount needs to be accumulated before using tools such as iron rakes to sweep them away. This method is highly dependent on manual labor and is not very efficient. In addition, using an air gun to blow away waste chips can easily blow them into rotating parts, which will cause wear on the rotating parts. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a gear machining lathe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gear processing lathe includes a frame and a fixed frame. The fixed frame is fixedly installed at the top of the frame. A vertically arranged back plate is fixedly connected to one top side of the fixed frame. A fixed end is fixedly installed on one side of the top of the fixed frame. A top block is fixedly installed on the other side of the top of the fixed frame. A contact switch is installed on the side wall of the top block near the fixed end. A slide rail is fixedly installed at the top of the fixed frame between the fixed end and the top block. A movable end is slidably connected on the slide rail. A collection mechanism including the movable block is provided between the fixed end and the movable end.

[0007] A first fixing block is fixedly installed horizontally at the bottom of the fixed end, and a second fixing block is fixedly installed horizontally at the bottom of the movable end. Three movable blocks are slidably connected to the bottom of the first fixing block and the top of the second fixing block.

[0008] Preferably, the side wall of the fixing frame away from the back plate is provided with an inclined side, and a collection bin is movably provided on the frame below the inclined side.

[0009] Preferably, a chuck is fixedly installed at the top of the fixed end, and a feed box is fixedly installed at the top of the movable end.

[0010] Preferably, a first motor is fixedly installed on the top of the fixing frame on one side of the fixed end, and the output end of the first motor is fixedly connected to a screw threaded to the center of the bottom of the movable end.

[0011] Preferably, the first fixed block, the second fixed block, and the movable block have the same structure, all of which are inclined at the bottom and top and horizontal in the middle. The bottom of the horizontal section of the first fixed block has two sliding grooves. The top of the horizontal section of the second fixed block is fixedly connected to two sliders that are adapted to the two sliding grooves. The top of the horizontal section of the movable block is fixedly connected to two sliders that are adapted to the two sliding grooves. The bottom of the horizontal section of the movable block has two sliding grooves. The first fixed block, the second fixed block, and the movable block are slidably connected in pairs through sliders and sliding grooves.

[0012] Preferably, two mounting blocks are symmetrically installed on the side of the back plate near the fixed frame, and a hollow rotating rod is rotatably installed between the opposite surfaces of the two mounting blocks. A long strip nozzle is provided on the side of the rotating rod near the fixed frame.

[0013] Preferably, the nozzle is connected to the hollow structure of the rotating rod, a second motor is installed in one mounting block, the output shaft of the second motor is fixedly connected to one end of the rotating rod, and an air pipe connected to the rotating rod is provided in another mounting block, the air pipe being connected to an external fan.

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

[0015] This utility model features a collection mechanism that slides between the first fixed block, the second fixed block, and the movable block, and is always kept below the cutter and chuck by the movement of the movable end. This ensures continuous collection of waste chips, preventing them from falling into the rotating parts and causing damage. It eliminates the need for workers to use an air gun to blow them away, resulting in high collection efficiency and strong stability.

[0016] This invention, by setting a rotating rod and a nozzle, allows the movable end to touch a contact switch when it moves to the side of the top block, away from the fixed end. The contact switch activates an external controller that controls a second motor to rotate the rotating rod until the nozzle is tilted and aligned with the movable block, thus blowing away the collected debris. The nozzle is also driven to rotate horizontally and vertically, allowing it to thoroughly blow away the debris. Before the contact switch activates, when processing gears, the nozzle is aligned with the gear blank to cool the tool and blank, improving processing quality and reducing damage to the tool and gear.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-7 A gear processing lathe includes a frame 1 and a fixed frame 3. The fixed frame 3 is fixedly installed at the top of the frame 1. A vertically arranged back plate 31 is fixedly connected to one top side of the fixed frame 3. A fixed end 5 is fixedly installed on one side of the top of the fixed frame 3. A top block 8 is fixedly installed on the other side of the top of the fixed frame 3. A contact switch is installed on the side wall of the top block 8 near the fixed end 5. A slide rail 6 is fixedly installed at the top of the fixed frame 3 between the fixed end 5 and the top block 8. A movable end 7 is slidably connected on the slide rail 6. A collection mechanism 11 including a movable block 14 is provided between the fixed end 5 and the movable end 7.

[0027] A first fixing block 12 is fixedly installed horizontally at the bottom of the fixed end 5, and a second fixing block 13 is fixedly installed horizontally at the bottom of the movable end 7. Three movable blocks 14 are slidably connected to the bottom of the first fixing block 12 and the top of the second fixing block 13. The contact switch is electrically connected to an external controller, as are the first motor 9 and the second motor. When the movable end 7 moves to the side of the top block 8, away from the fixed end 5, the side wall of the movable end 7 touches the contact switch. The action of the contact switch controls the second motor to rotate, causing the rotating rod 18 to rotate until the nozzle 19 is tilted and aligned with the movable block 14, thus blowing away the collected waste. The nozzle 19 is also driven to rotate horizontally and vertically, allowing it to thoroughly blow away the waste. Before the contact switch is activated, when the gear is being processed, the nozzle 19 is aligned with the gear blank to blow air and cool the tool and blank, improving processing quality and reducing damage to the tool and gear. The collection mechanism 11 can slide through the cooperation between the first fixed block 12, the second fixed block 13, and the movable block 14, and is always kept below the tool and chuck by the action of the movable end 7, ensuring continuous collection of waste and preventing it from falling into the rotating parts and causing damage. There is no need for workers to use an air gun for blowing, resulting in high collection efficiency and strong stability.

[0028] As a technical optimization of this utility model, the side wall of the fixed frame 3 away from the back plate 31 is provided with an inclined side 4, and the frame 1 below the inclined side 4 is movably provided with a collection chamber 2. When the waste chips generated by gear processing fall onto the top of the first fixed block 12, the second fixed block 13 and the movable block 14, they are blown into the collection chamber 2 by the nozzle 19 for collection. The collection chamber 2 is replaceable, and the inclined side 4 facilitates the falling of waste chips.

[0029] As a technical optimization of this utility model, a chuck is fixedly installed at the top of the fixed end 5, and a feed box is fixedly installed at the top of the movable end 7. The chuck is used to fix the gear blank, and the feed box is used to drive the tool to move and perform cutting and other machining on the blank.

[0030] As a technical optimization of this utility model, a first motor 9 is fixedly installed on the top of the fixing frame 3 on one side of the fixed end 5. The output end of the first motor 9 is fixedly connected to a screw 10 that is threaded to the bottom center of the movable end 7. The rotation of the first motor 9 drives the screw 10 to rotate, and the rotation of the screw 10 drives the movable end 7 to slide back and forth along the slide rail 6.

[0031] As a technical optimization of this utility model, the first fixed block 12, the second fixed block 13, and the movable block 14 have the same structure, all of which are inclined at the bottom and top and horizontal in the middle. The bottom of the horizontal section of the first fixed block 12 is provided with two sliding grooves 16. The top of the horizontal section of the second fixed block 13 is fixedly connected with two sliders 15 that are adapted to the two sliding grooves 16. The top of the horizontal section of the movable block 14 is fixedly connected with two sliders 15 that are adapted to the two sliding grooves 16. The bottom of the horizontal section of the movable block 14 is provided with two sliding grooves 16. The first fixed block 12, the second fixed block 13, and the movable block 14 are slidably connected in pairs through the sliders 15 and the sliding grooves 16. During the reciprocating sliding of the movable end 7 along the slide rail 6, the movable end 7 first slides towards the fixed end 5, driving the feed box to process the blank. When the movable end 7 moves, it drives the second fixed block 13 to move and causes the slider 15 to slide along the groove 16 at the bottom of an adjacent movable block 14. When the slider 15 slides to the end of the groove 16, it can push the movable block 14 to move along the second movable block 14 and cause the slider 15 at the top of the second movable block 14 to slide along the groove 16 at the bottom of the third movable block 14. This process is repeated until the second fixed block 13 and the three movable blocks 14 are stacked and slide below the first fixed block 12. When the movable end 7 moves away from the fixed end 5, it slides in the opposite direction, causing the second fixed block 13 and the three movable blocks 14 to slide out of the first fixed block 12 and finally reset. This ensures that the first fixed block 12, the second fixed block 13, and the movable blocks 14 can always be kept below the chuck and the feed box to collect waste, preventing waste from falling onto rotating parts such as the slide rail 6 and causing wear to the rotating parts.

[0032] As a technical optimization of this utility model, two mounting blocks 17 are symmetrically installed on the side of the back plate 31 near the fixed frame 3. A hollow rotating rod 18 is rotatably installed between the opposite surfaces of the two mounting blocks 17. A long strip nozzle 19 is provided on the side of the rotating rod 18 near the fixed frame 3. The nozzle 19 can blow away the waste collected on the first fixed block 12, the second fixed block 13, and the movable block 14 through an external fan, so that the waste is blown into the collection chamber 2. Since the rotating rod 18 can rotate, the first fixed block 12, the second fixed block 13, and the movable block 14 can be thoroughly blown away, reducing the residue of waste. In addition, the blowing can cool down the gear cutting tool, which is beneficial to protecting the tool and gear.

[0033] As a technical optimization of this utility model, the nozzle 19 is connected to the hollow structure of the rotating rod 18. A second motor is installed in one mounting block 17, and the output shaft of the second motor is fixedly connected to one end of the rotating rod 18. An air pipe connected to the rotating rod 18 is provided in another mounting block 17, and the air pipe is connected to an external fan. The second motor can drive the rotating rod 18 to rotate so that the nozzle 19 can fully blow the first fixed block 12, the second fixed block 13 and the movable block 14 and cool the cutting tool. Since the rotation angle of the rotating rod 18 does not exceed 180 degrees, the installation of the air pipe does not need to consider the winding problem caused by rotation. It only needs to be directly connected to the rotating rod 18 and leave a cavity in another mounting block 17 larger than the diameter of the air pipe to meet the movement of the air pipe.

[0034] In use, the gear blank is mounted on the chuck, and the first motor 9 is controlled to rotate. The rotation of the first motor 9 drives the screw 10 to rotate. The rotation of the screw 10 drives the movable end 7 to move along the slide rail 6 towards the fixed end 5. During the movement, the movable end 7 drives the second fixed block 13 to move and causes the slider 15 to slide along the slide groove 16 at the bottom of an adjacent movable block 14. When the slider 15 slides to the end of the slide groove 16, it can push the movable block 14 to move along the second movable block 14 and cause the slider 15 at the top of the second movable block 14 to slide along the slide groove 16 at the bottom of the third movable block 14. This process is repeated until the second fixed block 13 and the three movable blocks 14 are stacked and slide down to the bottom of the first fixed block 12. After they are in place, the feed box starts the tool to process the gear blank. The processing waste falls onto the first fixed block 12, the second fixed block 13 and the movable block 14 for collection. The nozzle 19 is aimed at the gear blank to blow air and cool the tool and the blank.

[0035] After processing, the first motor 9 reverses and drives the movable end 7 away from the fixed end 5. The reverse sliding causes the second fixed block 13 and the three movable blocks 14 to slide out from under the first fixed block 12 in sequence and finally reset and unfold. Finally, the side wall of the movable end 7 touches the contact switch. The contact switch action controls the second motor to rotate through the external controller, which drives the rotating rod 18 to rotate until the nozzle 19 is tilted and aligned with the movable block 14, blowing away the collected waste. It also drives the nozzle 19 to rotate in the horizontal and vertical directions, so that the nozzle 19 can thoroughly blow away the waste. The waste blown away by the nozzle 19 falls through the inclined side 4 and into the collection chamber 2 for collection.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
