Description

Technical Field

[0001] This application relates to the field of parts processing, and in particular to a portable spinning device for processing cylindrical parts. Background Technology

[0002] Spinning is a process that uses rotating tools (such as rollers or cutters) to apply pressure to the surface of a workpiece to process parts. Some spinning devices are easy to move and are suitable for on-site processing.

[0003] Some existing portable spinning devices require workers to hold the part to be processed and place it under the spinning roller when processing cylindrical parts. The part is processed by controlling the contact between the roller and the surface of the part. However, manually picking up the part is quite dangerous. Some devices use clips to fix the part, but this method is inconvenient to fix the part because the clips are small. Moreover, the spinning tool is difficult to move during the spinning process, and it is not possible to process different parts of the part, which reduces the practicality of the device. Utility Model Content

[0004] This application provides a portable spinning device for machining cylindrical parts. When machining cylindrical parts, the device can fix the parts to prevent the parts from shifting during machining. The fixing method is simple. When spinning cylindrical parts, different positions of the parts can be spun, which improves the practicality of the device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a portable spinning device for machining cylindrical parts, the device comprising:

[0006] ontology;

[0007] A bidirectional lead screw is mounted on both sides of the inner wall of the body via bearings, and two sleeves are threaded on the outer surface of the bidirectional lead screw. The bidirectional lead screw can rotate via bearings. There are two thread grooves with different helical directions on the outer surface of the bidirectional lead screw, and the two sleeves are respectively connected to the two thread grooves with different helical directions on the outer surface of the bidirectional lead screw.

[0008] Two limiting plates are fixedly set on the outer surfaces of the two bidirectional lead screws respectively, and one side of the two limiting plates is slidably set on one side of the inner wall of the main body. The two limiting plates can slide on one side of the inner wall of the main body, so that when the bidirectional lead screw rotates in different directions, the two sleeves move in relative or opposite directions on the outer surface of the bidirectional lead screw.

[0009] Two support plates are fixedly mounted on the outer surfaces of the two sleeves respectively, and a first sleeve rod is fixedly mounted on one side of each of the two support plates. The two sleeves move relative to each other, and the two arc-shaped plates move relative to each other through the two support plates.

[0010] Two second sleeve rods are movably embedded on one side of two first sleeve rods, and an arc-shaped plate is fixedly provided at the opposite end of each of the two second sleeve rods. The two second sleeve rods can slide on the inner wall of the two first sleeve rods respectively.

[0011] As a further improvement of this application: a turntable is fixedly provided on one side of the bidirectional lead screw, and baffles are fixedly sleeved on the outer surfaces of the two second sleeve rods. The two second sleeve rods slide to the inner walls of the two first sleeve rods, and the two baffles squeeze the two springs respectively at this time.

[0012] As a further improvement of this application: springs are fixedly provided on the opposite sides of the two baffles, and the two springs are respectively movably sleeved on the outer surfaces of the two second sleeve rods. When the two springs are compressed, they will generate opposite forces.

[0013] As a further improvement of this application: a protective box is provided on one side of the main body by screws, and a bidirectional motor is installed on one side of the main body. The protective box protects its internal structure, preventing it from being exposed and damaged. The protective box can be removed by rotating the screws.

[0014] As a further improvement of this application: the output shaft of the bidirectional motor is fixedly provided with a rotating rod, and a gear is fixedly sleeved on the outer surface of the rotating rod. When the external power switch of the bidirectional motor is turned on, the output shaft of the bidirectional motor can rotate in both directions, so that the rotating rod drives the gear to rotate in different directions.

[0015] As a further improvement of this application: a rack is meshed on the outer surface of the gear, and the rack is slidably disposed on the side of the body close to the protective box. The rotating rod drives the gear to rotate, which further causes the rack to move.

[0016] As a further improvement of this application: a transmission plate is fixedly provided on one side of the rack, and a hydraulic rod is installed on one side of the transmission plate. When the rack slides to different positions on one side of the body, the transmission plate drives the spinning roller to move to different positions.

[0017] As a further improvement of this application: the output end of the hydraulic rod is provided with a spinning roller, and handles are provided on both sides of the main body. When the switch of the hydraulic rod is turned on, the output end of the hydraulic rod is controlled to drive the spinning roller to press down, so that the roller on the spinning roller contacts the surface of the part and spins the surface of the part. The handles make it convenient for the operator to lift the main body for easy carrying.

[0018] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0019] 1. In this application, when machining a cylindrical part, the main body's door is opened, and two second sleeve rods can slide along the inner walls of the two first sleeve rods, pushing two arc-shaped plates to both sides. This causes the two second sleeve rods to slide to the inner walls of the two first sleeve rods, and the two baffles at this time compress the two springs. When the two springs are compressed, they generate a counterforce. At this time, the cylindrical part is placed in the middle position of the two arc-shaped plates. The compression of the two arc-shaped plates is released, and the counterforce generated by the two springs pushes the two baffles, further causing the two second sleeve rods to push the two arc-shaped plates, so that the two arc-shaped plates clamp the part. The outer surface of the bidirectional lead screw has two different spirals. The two sleeves are connected to two threaded grooves with different helical directions on the outer surface of the double-acting screw, and the two limiting plates can slide on one side of the inner wall of the main body. Thus, when the double-acting screw rotates in different directions, the two sleeves move in relative or opposite directions on the outer surface of the double-acting screw. At this time, the double-acting screw is rotated by rotating the turntable clockwise, which further causes the two sleeves to move relative to each other. The two arc-shaped plates are moved relative to each other by the two support plates. When the turntable is difficult to rotate, the two arc-shaped plates fix the cylindrical part inside the main body. Thus, the part is fixed during the machining of the cylindrical part, preventing the part from shifting during machining. The fixing method is simple.

[0020] 2. In this application, when spinning cylindrical parts, by turning on the switch of the hydraulic rod, the output end of the hydraulic rod is controlled to drive the spinning roller to press down, so that the roller on the spinning roller contacts the surface of the part, and the surface of the part is spun. When the external power switch of the bidirectional motor is turned on, the output shaft of the bidirectional motor can rotate in both directions, so that the rotating rod drives the gear to rotate in different directions. Furthermore, when the rack slides to different positions on one side of the body, the spinning roller is moved to different positions through the transmission plate. The handle makes it easy for the operator to lift the body. Thus, when spinning cylindrical parts, spinning can be performed on different positions of the part, improving the practicality of the device. Attached Figure Description

[0029] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways than those described herein, and therefore this application is not limited to the specific embodiments disclosed in the following specification.

[0031] Example 1, such as Figures 1 to 7 As shown, this application provides a portable spinning device for machining cylindrical parts, the device comprising:

[0032] Ontology 1;

[0033] The bidirectional lead screw 201 is mounted on both sides of the inner wall of the body 1 via bearings, and two sleeves 202 are threaded on the outer surface of the bidirectional lead screw 201. The bidirectional lead screw 201 can rotate via bearings. There are two thread grooves with different helical directions on the outer surface of the bidirectional lead screw 201. The two sleeves 202 are respectively connected to the two thread grooves with different helical directions on the outer surface of the bidirectional lead screw 201.

[0034] Two limiting plates 203 are respectively fixedly set on the outer surface of two bidirectional screws 201, and one side of the two limiting plates 203 is slidably set on one side of the inner wall of the body 1. The two limiting plates 203 can slide on one side of the inner wall of the body 1, so that when the bidirectional screws 201 rotate in different directions, the two sleeves 202 move in relative or opposite directions on the outer surface of the bidirectional screws 201.

[0035] Two support plates 204 are fixedly mounted on the outer surfaces of two sleeves 202 respectively, and a first sleeve rod 205 is fixedly mounted on the opposite side of each of the two support plates 204. The two sleeves 202 move relative to each other, and the two arc-shaped plates 207 move relative to each other through the two support plates 204.

[0036] Two second sleeve rods 206 are respectively movably embedded on one side of two first sleeve rods 205, and an arc-shaped plate 207 is fixedly provided at the opposite end of each of the two second sleeve rods 206. The two second sleeve rods 206 can slide on the inner wall of the two first sleeve rods 205 respectively.

[0037] like Figures 1 to 7 As shown, a turntable 2 is fixedly installed on one side of the bidirectional lead screw 201, and baffles 208 are fixedly sleeved on the outer surfaces of the two second sleeve rods 206. The two second sleeve rods 206 slide to the inner wall of the two first sleeve rods 205, and the two baffles 208 squeeze the two springs 209 respectively at this time.

[0038] like Figures 1 to 7 As shown, springs 209 are fixedly installed on opposite sides of the two baffles 208. The two springs 209 are respectively movably sleeved on the outer surfaces of the two second sleeve rods 206. When the two springs 209 are squeezed, they will generate opposite forces.

[0039] like Figures 1 to 7 As shown, a protective box 3 is installed on one side of the main body 1 by screws, and a bidirectional motor 301 is installed on one side of the main body 1. The protective box 3 protects its internal structure and prevents it from being exposed and damaged. The protective box 3 can be removed by turning the screws.

[0040] like Figures 1 to 7 As shown, a rotating rod 302 is fixedly installed on the output shaft of the bidirectional motor 301, and a gear 303 is fixedly sleeved on the outer surface of the rotating rod 302. When the external power switch of the bidirectional motor 301 is turned on, the output shaft of the bidirectional motor 301 can rotate in both directions, so that the rotating rod 302 drives the gear 303 to rotate in different directions.

[0041] like Figures 1 to 7 As shown, a rack 304 is meshed on the outer surface of the gear 303. The rack 304 is slidably disposed on the side of the body 1 near the protective box 3. The rotating rod 302 drives the gear 303 to rotate, which further causes the rack 304 to move.

[0042] like Figures 1 to 7 As shown, a transmission plate 305 is fixedly installed on one side of the rack 304, and a hydraulic rod 306 is installed on one side of the transmission plate 305. When the rack 304 slides to different positions on one side of the body 1, the transmission plate 305 drives the spinning roller 307 to move to different positions.

[0043] like Figures 1 to 7 As shown, the output end of the hydraulic rod 306 is equipped with a spinning roller 307, and the two sides of the main body 1 are equipped with handles 308. When the switch of the hydraulic rod 306 is turned on, the output end of the hydraulic rod 306 is controlled to drive the spinning roller 307 to press down, so that the roller on the spinning roller 307 contacts the surface of the part and spins the surface of the part. The handles 308 make it convenient for the operator to lift the main body 1 for easy carrying.

[0044] Working principle: When machining a cylindrical part, the door of the main body 1 is opened, and the two second sleeve rods 206 can slide on the inner walls of the two first sleeve rods 205 respectively, pushing the two arc-shaped plates 207 to both sides, so that the two second sleeve rods 206 slide to the inner walls of the two first sleeve rods 205. At this time, the two baffles 208 squeeze the two springs 209 respectively. When the two springs 209 are squeezed, they will generate a counterforce. At this time, the cylindrical part is placed in the middle position of the two arc-shaped plates 207. The squeezing of the two arc-shaped plates 207 is released, and the two springs 209 generate... The opposing force pushes the two baffles 208, which in turn causes the two second sleeve rods 206 to push the two arc-shaped plates 207, clamping the parts together. The outer surface of the bidirectional lead screw 201 has two threaded grooves with different helical directions. The two sleeves 202 are connected to these grooves on the outer surface of the bidirectional lead screw 201, and the two limiting plates 203 can slide on one side of the inner wall of the body 1. Therefore, when the bidirectional lead screw 201 rotates in different directions, the two sleeves 202 move in opposite or relative directions on the outer surface of the bidirectional lead screw 201. At this time, through the forward and reverse rotation... The clockwise rotation of turntable 2 drives the bidirectional lead screw 201 to rotate, further causing the two sleeves 202 to move relative to each other. The two support plates 204 cause the two arc-shaped plates 207 to move relative to each other. When turntable 2 is difficult to rotate, the two arc-shaped plates 207 fix the cylindrical part inside the body 1, thus fixing the part during machining and preventing displacement. The fixing method is simple. During the spinning process of the cylindrical part, by opening the switch of hydraulic rod 306, the output end of hydraulic rod 306 drives the spinning roller 307 downwards, causing the spinning roller to spin. The roller on the pressure roller 307 contacts the surface of the part and performs spinning processing on the part surface. When the external power switch of the bidirectional motor 301 is turned on, the output shaft of the bidirectional motor 301 can rotate in both directions, causing the rotating rod 302 to drive the gear 303 to rotate in different directions. Furthermore, when the rack 304 slides to different positions on one side of the body 1, the transmission plate 305 drives the spinning roller 307 to move to different positions. The handle 308 makes it easy for the operator to lift the body 1. Thus, when spinning cylindrical parts, spinning processing can be performed on different positions of the part, improving the practicality of the device.

[0045] The above are merely preferred embodiments and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
