Description

Technical Field

[0001] This utility model relates to the field of roller processing technology, and in particular to a double-end lathe with automatic upper and lower rollers. Background Technology

[0002] In industrial production, rollers are important transmission and support components, widely used in papermaking, printing, textiles, packaging, conveying and other fields. The machining accuracy at both ends of the rollers directly affects the operational stability and service life of the equipment. For the machining of the roller ends, double-end lathes have become the mainstream machining equipment due to their advantage of being able to perform simultaneous machining at both ends in one clamping.

[0003] In the current process of machining rollers on double-end lathes, the loading and unloading process is still generally carried out manually. The roller blanks to be processed are manually moved to the fixture position of the double-end lathe for loading and unloading. This manual loading and unloading method has the following problems: First, the machining cycle of double-end lathes is usually short, while the manual loading and unloading process involves multiple steps such as handling, positioning, clamping, and disassembly, which takes a long time and causes the equipment to be in a waiting state frequently, making it difficult to achieve automated production; Second, the manual handling process is not only extremely labor-intensive, but also prone to damage to the rollers due to workpiece slippage and collision, reducing the yield rate of roller processing. Utility Model Content

[0004] To address one or more of the aforementioned problems, this utility model provides a double-end lathe with automatic upper and lower rollers.

[0005] According to one aspect of the present invention, an automatic double-end lathe with upper and lower rollers includes: a lathe frame, a machining assembly, two load-bearing assemblies, and a pusher assembly.

[0006] The machining assembly is installed in the middle of the lathe frame, and two load-bearing assemblies are respectively set on the two sides of the machining assembly. The pusher assembly is installed on either load-bearing assembly.

[0007] The load-bearing component includes a support plate and a support base. The support plate is provided with a V-shaped part. The bottom end of the support base is fixedly connected to the lathe frame, and the support plate is slidably connected to the support base.

[0008] The pushing assembly includes a second moving device mounted on a support plate. The moving end of the second moving device is equipped with a pushing plate. The pushing plate pushes an unprocessed roller on a V-shaped part into the processing assembly through the second moving device to complete the roller loading. Meanwhile, the processed roller in the processing assembly is simultaneously pushed onto another V-shaped part to complete the roller unloading.

[0009] In some embodiments, the V-shaped component includes a fixed frame fixedly connected to a support plate and two half-Y-shaped plates. The fixed frame has a mounting groove, and the vertical ends of the two half-Y-shaped plates are fixedly connected to the mounting groove. The inclined ends of the two half-Y-shaped plates are located above the fixed frame, and a gap is left between the two half-Y-shaped plates.

[0010] In some implementations, guide pads are installed on the inclined ends of both half-Y plates.

[0011] In some embodiments, a detector is mounted on the mounting bracket, and through slots matching the detector are provided on both the semi-Y-shaped plate and the guide pad.

[0012] In some embodiments, a fixed seat is fixedly connected to the upper surface of the support base, and a slide rail is fixedly connected to the bottom surface of the support plate, with the slide rail slidably connected to the fixed seat.

[0013] In some embodiments, the machining assembly includes two spindle boxes and two turret structures. The bottom ends of the two spindle boxes are mounted on the lathe frame, and the two turret structures are respectively located on opposite sides of the two spindle boxes, and the two turret structures are symmetrical.

[0014] In some embodiments, the first moving device is selected from electric actuators, pneumatic cylinders, or hydraulic cylinders.

[0015] In some embodiments, a mounting block is mounted on the second moving device, and the second moving device is detachably mounted to the support plate by means of the mounting block and bolts.

[0016] In some embodiments, the end of the pusher plate away from the second moving device is located above the V-shaped member, and a silicone plate is fixedly connected to the pusher surface of the pusher plate.

[0017] In some embodiments, the second moving device is a linear slide, a ball screw module, or a hydraulic cylinder.

[0018] The beneficial effects of this utility model are as follows: 1. This utility model, through the cooperative arrangement of the bearing component and the pushing component, can drive the pushing plate to push the roller to be processed on the V-shaped part to the processing component, and at the same time push the processed roller in the processing component to the bearing component on the other side, so as to realize the synchronous completion of loading and unloading actions, with a high degree of automation. It solves the problems of cumbersome and time-consuming manual loading and unloading steps and the mismatch with the short processing cycle of double-end lathes. It also reduces the damage such as roller slippage and collision caused by manual handling, and effectively improves the yield of roller processing. 2. By setting up a support base, slide rail, fixed base, and first moving device, the support plate and V-shaped parts can be moved precisely to the loading and unloading positions of the spindle box, ensuring the stability of the loading and unloading process. The V-shaped parts of the load-bearing components adopt a design of half Y-shaped plate and polyethylene guide pad, which can reduce the friction when the roller moves, ensure smooth movement, and avoid scratches on the roller surface. In addition, by adding a silicone plate to the pushing surface of the pusher plate, damage caused by hard contact with the roller during the pushing process can be prevented.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively. Example 1

[0021] Please see Figures 1 to 3 As shown, this utility model provides a double-end lathe with automatic upper and lower rollers, including a lathe frame 1, a processing component 2, two load-bearing components 3 and a pusher component 4.

[0022] The machining component 2 is installed in the middle of the lathe frame 1, and two load-bearing components 3 are respectively set on the two sides of the machining component 2. The pusher component 4 is installed on any one of the load-bearing components 3.

[0023] The load-bearing component 3 includes a support plate 31 and a support base 37. The support plate 31 is provided with a V-shaped part, and the bottom end of the support base 37 is fixedly connected to the lathe frame 1, while the support plate 31 is slidably connected to the support base 37.

[0024] The cylindrical roller is supported by a V-shaped component, which is applicable to rollers of different diameters. The support plate 31 is placed above the lathe frame 1 via the support base 37, which enables the roller supported by the V-shaped component on the support plate 31 to have the same feeding height as the processing component 2.

[0025] The pushing assembly 4 includes a second moving device 41 mounted on the support plate 31. The moving end of the second moving device 41 is equipped with a pushing plate 43. The pushing plate 43 pushes an unprocessed roller on a V-shaped part into the processing assembly 2 in a transverse direction through the second moving device 41 to complete the roller loading. Meanwhile, the processed roller in the processing assembly 2 is simultaneously pushed onto another V-shaped part to complete the roller unloading.

[0026] In the process of loading and unloading the rollers, the rollers are placed on a V-shaped part, and the rollers are moved on the V-shaped part to the processing assembly 2 by means of the moving end of the second moving device 41. At this time, the rollers that have been processed in the processing assembly 2 will be moved from the processing assembly 2 to another V-shaped part under the pushing action of the rollers in the current moving state, while the unprocessed rollers will be loaded into the processing assembly 2 for processing.

[0027] Based on the above embodiments, the V-shaped component includes a fixed frame 32 fixedly connected to the support plate 31 and two half-Y plates 34. The fixed frame 32 has an installation groove 33. The vertical ends of the two half-Y plates 34 are fixedly connected to the installation groove 33. The inclined ends of the two half-Y plates 34 are located above the fixed frame 32, and a gap is left between the two half-Y plates 34.

[0028] The two half-Y plates 34 can form a Y-shaped structure. The mounting groove 33 completes the connection between the fixing frame 32 and the half-Y plate 34, and the inclined part of the half-Y plate 34 abuts against the roller to support it.

[0029] Furthermore, guide pads 35 are installed on the inclined ends of both half-Y plates 34.

[0030] To further improve the stability of the roller during movement and reduce surface scratches during roller movement, the guide pad 35 is made of polyethylene, which can reduce the friction when the roller moves laterally, has strong self-lubricating properties, and can achieve smooth roller movement without additional lubrication.

[0031] Preferably, a detector 36 is installed on the fixing frame 32, and through grooves 38 matching the detector 36 are opened on the semi-Y plate 34 and the guide pad 35.

[0032] By using the through groove 38, the detection end of the detector 36 can directly detect the inside of the V-shaped part, which can monitor in real time whether there is a roller on the V-shaped part. The detector 36 uses an inductive proximity sensor, which determines the presence of the roller by sensing the electromagnetic induction change of the metal conductor.

[0033] Furthermore, the machining assembly 2 includes two spindle boxes 21 and two turret structures 22. The bottom ends of the two spindle boxes 21 are mounted on the lathe frame 1. The two turret structures 22 are respectively located on opposite sides of the two spindle boxes 21, and the two turret structures 22 are symmetrical.

[0034] Both spindle boxes 21 contain a spindle, a servo motor and a transmission mechanism, which can rotate independently or synchronously to achieve simultaneous processing at both ends. They are also equipped with hydraulic or pneumatic clamps for clamping the rollers.

[0035] Both turret structures 22 are equipped with cutting tools, and the turret structures 22 are equipped with a moving structure that can move the turret structures 22 to one side when loading and unloading the spindle box 21, so as to avoid the cutting tools on the turret structures 22 obstructing the roller when loading and unloading the roller.

[0036] Preferably, the second moving device 41 is equipped with a mounting block 42, and the second moving device 41 is detachably mounted on the support plate 31 via the mounting block 42 and bolts.

[0037] Both the mounting block 42 and the support plate 31 are equipped with through holes, and the mounting block 42 can be fixed to the support plate 31 with bolts and nuts, thereby completing the connection between the second moving device 41 and the support plate 31.

[0038] Furthermore, the end of the pusher plate 43 away from the second moving device 41 is located above the V-shaped part, and a silicone plate is fixedly connected to the pusher surface of the pusher plate 43.

[0039] The pusher plate 43 moves laterally to push the roller on the V-shaped part for feeding, and the silicone plate on the pushing surface of the pusher plate 43 can prevent scratches from occurring when the pusher plate 43 comes into hard contact with the roller.

[0040] Preferably, the second moving device 41 is a linear slide, a ball screw module, or a hydraulic cylinder.

[0041] Linear slides, ball screw modules, or hydraulic cylinders are all linear mobile devices. Conventional methods can be used for fixing and heat dissipation. This application does not make any improvements to this part. Those skilled in the art can implement it using conventional technical means.

[0042] The second moving device 41 is used to drive the pusher plate 43 to move, thereby completing the feeding of the roller.

[0043] With the coordinated arrangement of the bearing component 3 and the pushing component 4, the pushing component 4 can drive the pushing plate 43 to push the roller to be processed on the V-shaped part to the processing component 2. At the same time, it can push the processed roller in the processing component 2 to the bearing component 3 on the other side, realizing the synchronous completion of loading and unloading actions. It has a high degree of automation and solves the problems of cumbersome and time-consuming manual loading and unloading steps and the mismatch with the short processing cycle of the double-end lathe. It also reduces the damage caused by roller slippage and collision due to manual handling, and effectively improves the yield of roller processing.

[0044] The working principle of this embodiment is as follows: In use, the roller to be processed is first hoisted onto the V-shaped part of one of the bearing components 3 by a crane or electric hoist. The second moving device 41 is started, and the second moving device 41 drives the pusher plate 43 to move. The pusher plate 43 pushes the unprocessed roller on the V-shaped part into the processing component 2. At this time, the two spindle boxes 21 of the processing component 2 can clamp and fix the two ends of the roller. At the same time, the cutting tools on the two turret structures 22 perform synchronous processing on the two ends of the roller. During the processing, the V-shaped part of the other bearing component 3 is in a waiting state for unloading.

[0045] After the roller processing is completed, the above loading operation is repeated. The unprocessed roller on the V-shaped part is pushed into the processing component 2 by the pusher plate 43. The unprocessed roller will abut against the processed roller and push it. The processed roller in the processing component 2 is pushed to the V-shaped part of another bearing component 3 to complete the unloading. At the same time, a new unprocessed roller is loaded into the processing component 2. This cycle is repeated to realize automatic loading and unloading and continuous processing of rollers. The whole process does not require frequent manual handling of rollers, which greatly improves processing efficiency, reduces labor intensity, reduces the damage to rollers caused by manual handling, and improves the yield of roller processing. Example 2

[0046] The difference between this embodiment and Embodiment 1 is that: Figures 1 to 3 As shown, a fixed seat 371 is fixedly connected to the upper surface of the support base 37, and a slide rail 372 is fixedly connected to the bottom surface of the support plate 31, and the slide rail 372 is slidably connected to the fixed seat 371.

[0047] With the help of the fixed seat 371 and the slide rail 372, the support plate 31 can slide horizontally on the support seat 37. That is to say, whether it is loading or unloading, the support plate 31 will drive the V-shaped part to move to the loading and unloading position of the spindle box 21 to receive the material, ensuring the stability of loading and unloading.

[0048] A first moving device 373 is installed on the bottom surface of the support plate 31, and the telescopic end of the first moving device 373 is installed on the support base 37. The first moving device 373 is selected as an electric push rod, a pneumatic cylinder, or a hydraulic cylinder.

[0049] The support plate 31 moves away from the main shaft box 21 by extending the telescopic end of the first moving device 373, and the support plate 31 moves closer to the main shaft box 21 by retracting the telescopic end of the first moving device 373, so as to receive the material from the roller.

[0050] The working principle of this embodiment is as follows: First, place the roller to be processed on the V-shaped part of one of the bearing components 3, start the first moving device 373, the telescopic end of the first moving device 373 extends, pushes the support plate 31 to slide horizontally on the support seat 37, so that the V-shaped part moves to the loading position of the spindle box 21.

[0051] Next, the second moving device 41 is started, which drives the pusher plate 43 to move. The pusher plate 43 pushes the unprocessed roller on the V-shaped part into the processing assembly 2. At this time, the two spindle boxes 21 of the processing assembly 2 clamp and fix the two ends of the roller, and the cutting tools on the two turret structures 22 perform synchronous processing on the two ends of the roller.

[0052] During the processing, the V-shaped part of another bearing component 3 moves to the unloading position of the spindle box 21 under the action of the first moving device 373 to wait for unloading.

[0053] After the roller processing is completed, the second moving device 41 is started again to push the new unprocessed roller into the processing assembly 2. The new roller abuts against the processed roller and pushes it, and the processed roller in the processing assembly 2 is pushed to the V-shaped part of another bearing assembly 3 to complete the unloading. At the same time, the new unprocessed roller is loaded into the processing assembly 2. Then the telescopic end of the first moving device 373 retracts, so that the support plate 31 drives the V-shaped part back to the initial position. This cycle is repeated to realize the automatic loading and unloading and continuous processing of the roller.

[0054] The entire process eliminates the need for frequent manual handling of the rollers, improving processing efficiency, reducing labor intensity, minimizing roller damage, and increasing yield.

[0055] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
