Description

Technical Field

[0001] The utility model belongs to the technical field of roller processing, and in particular relates to a chamfering device for a roller. Background Art

[0002] Rollers are the main working parts and tools on the rolling mill that can make the rolled metal produce continuous plastic deformation. They are mainly composed of three parts: the roll body, the roll neck and the shaft head. The rolling mill usually uses the pressure generated by a pair or a group of rolls to roll the metal. In the process of producing rolls, in order to consider factors such as installation and plate shape control, the two ends of the rolls will be chamfered.

[0003] However, in the prior art, when a roller is chamfered using an ordinary lathe, it is necessary to first fix one end of the roller using a chuck and then use a turning tool to process the unfixed end of the roller. Due to the influence of factors such as the roller's own weight and the roller's large movement when it turns, the roller clamping, tool alignment and other operations take a long time. Therefore, a chamfering device for rollers is proposed. Utility Model Content

[0026] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings.

[0028] In this embodiment, the lifting assembly 1 includes a base 101, a leveling foot 102 is fixedly connected to the bottom of the base 101, a telescopic rod 103 is fixedly connected to the top of the base 101, a lifting frame 104 is fixedly connected between the telescopic ends of the telescopic rod 103, an end seat 105 is fixedly connected inside the base 101, a bidirectional lead screw 106 is movably connected between the end seats 105, a knob 107 is fixedly connected to one end of the bidirectional lead screw 106, a first support 108 is fixedly connected to the outer side of the bidirectional lead screw 106, a second support 109 is fixedly connected to the lower side of the lifting frame 104, and a support rod 110 is arranged between the first support 108 and the second support 109; the end seat 105 is rotatably connected to the bidirectional lead screw 106 The bidirectional lead screw 106 is connected to the first support 108 by threads, and the first support 108 and the second support 109 are both rotatably connected to the support rod 110; the horizontal degree of the device is adjusted by the leveling foot 102, the movable range of the lifting frame 104 is limited by the telescopic rod 103, and its lifting and lowering are guided, the movable range of the bidirectional lead screw 106 in the base 101 is limited by the end seat 105, and the bidirectional lead screw 106 is rotated by the knob 107. When the bidirectional lead screw 106 rotates relative to the end seat 105, its rotation will be transmitted to the lifting frame 104 through the first support 108, the support rod 110, and the second support 109, thereby driving the lifting frame 104 to rise and fall relative to the base 101.

[0029] In this embodiment: the reversing assembly 2 includes a transverse member that can drive one end of the roller to enter or leave the lathe chuck, a rotating member that can drive the roller to rotate horizontally to change the direction of the roller, and a limit member that can limit the horizontal rotation of the roller. The transverse member includes a guide rail 201 fixedly connected to the lifting assembly 1, a plug-in block 202 is movably connected to the guide rail 201, and a transverse frame 203 is arranged on one side of the plug-in block 202. The rotating member includes a carrier 204 fixedly connected to the transverse frame 203, a reversing frame 205 is arranged on the carrier 204, and a rotating shaft is fixedly connected to the lower side of the reversing frame 205 206, the outer side of the rotating shaft 206 is movably connected with the shaft seat 207, and the lower side of the reversing frame 205 is also fixedly connected with a load-bearing universal ball 208. The limiting member includes a limiting block 209 fixedly installed on the transverse frame 203, and a plug rod 210 is movably connected between the limiting blocks 209. The outer side of the plug rod 210 is movably connected with a spring 211, and one end of the plug rod 210 is fixedly connected with a handle 212; the plug block 202 and the transverse frame 203 are both slidably connected to the guide rail 201, the rotating shaft 206 is rotatably connected to the shaft seat 207, and the rotating shaft 206 and the limiting block 209 are both slidably connected to the plug rod 210 The movable range of the traverse frame 203 is limited by the guide rail 201, and the position of the traverse frame 203 on the guide rail 201 is locked by the plug-in block 202. Specifically, after the plug-in block 202 is removed from the guide rail 201, the traverse frame 203 can move laterally on the guide rail 201. After the plug-in block 202 is located on one side of the traverse frame 203 and connected to the guide rail 201, the traverse frame 203 will not be able to move laterally. A certain height difference is made between the reversing frame 205 and the traverse frame 203 by the carrier 204, and at the same time, the shaft seat 207 that can limit the movable range of the rotating shaft 206 is installed The reversing frame 205 is installed by the rotating shaft 206 to enable it to rotate relative to the carrier 204, and the load-bearing universal ball 208 is used to support both sides of the reversing frame 205 to prevent the reversing frame 205 from being deformed due to the load-bearing, and the insertion rod 210 is installed on the transverse frame 203 by the limit block 209. The rotation of the rotating shaft 206 is limited by the connection between the insertion rod 210 and the rotating shaft 206, and the movable range of the insertion rod 210 is limited by the spring 211 to prevent the insertion rod 210 from moving when it is not subjected to external force. The staff can easily pull the insertion rod 210 through the pull handle 212 to separate it from the rotating shaft 206.

[0030] In this embodiment: the support assembly 3 includes a roller frame 301 fixedly mounted on the reversing frame 205, and a roller 302 is movably connected inside the roller frame 301; the roller frame 301 is rotatably connected to the roller 302; the roller 302 is installed above the reversing frame 205 through the roller frame 301, and the roller 302 contacts the roller to be chamfered and lifts it up.

[0031] Working principle: When the device is installed and used for chamfering of the roll, after adjusting the distance between the two sets of support components 3 according to the size of the roll, the device is placed in the lathe, and then the roll is centered between the support components 3; after the placement is completed, the position of the device and the roll in the lathe is adjusted by moving the device as a whole, adjusting the height of each leveling foot 102, and turning the knob 107 to adjust the height of the lifting frame 104, so as to adjust the position of the device and the roll in the lathe, so as to adjust the side of the roll close to the lathe chuck adjacent to the chuck. The chuck is positioned at the same position as the roller, and the center line of the roller coincides with the center line of the chuck; after the adjustment is completed, the plug-in block 202 can be removed from the side of the chuck close to the chuck when the chuck is ready, and then the chuck is pushed to move the chuck toward the chuck, and the plug-in block 202 is placed on the guide rail 201 on the other side of the chuck, so that the chuck 203 cannot move again on the guide rail 201 after the movement. When the chuck 203 moves horizontally, one end of the roller will enter the chuck to a certain depth, so that the chuck can clamp the roller; wait for After the roller is clamped, the roller can be chamfered by a lathe according to the chamfering requirements; when one end of the roller is processed, the connection between the chuck and the roller can be separated, and then the roller can be separated from the chuck and the direction can be reversed without significantly moving the roller by removing the plug-in block 202, horizontally moving the transverse frame 203, horizontally pulling the plug-in rod 210 by the pull handle 212, rotating the reversing frame 205 by 180 degrees, resetting the plug-in rod 210, resetting the transverse frame 203, and resetting the plug-in block 202. And enter the chuck again to a certain depth, and then after the chuck clamps the roller again, the remaining chamfering work of the roller can be completed by the lathe; when it is necessary to continue chamfering other rollers of the same specification, the roller in the lathe can be separated from the chuck, and the plug-in block 202 can be removed, and then the transverse frame 203 can drive the processed roller to move transversely. After the roller is completely separated from the chuck, the processed roller can be removed, and the roller to be processed can be placed centrally on the support assembly 3, and then chamfered in the above manner.

[0032] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
