Description

Technical Field

[0001] The present invention relates to the technical field of end - cover milling, and particularly to a milling device for machining the end - cover surface of a bearing. Background Technique

[0002] The main bearing cover of a diesel engine is a very important component in a diesel engine, usually used to support the crankshaft of the engine and ensure its normal operation. The main function of the main bearing cover is to fix and support the main bearing, and its connection with the engine body can withstand the huge load generated during the operation of the engine. When machining the end - cover surface of the main bearing of a diesel engine, inclined - plane milling is required. In the prior art, when milling the inclined plane of the main bearing cover, the main bearing cover is only clamped by a simple fixture, with poor positioning effect. After milling the inclined plane, the main bearing cover needs to be replaced, and then the inclined - plane milling continues. The disassembly and assembly are inconvenient, which is not conducive to mass production, and it is difficult to control the dimensions during the inclined - plane milling process. Summary of the Invention

[0003] In view of the above - mentioned technical problems, the technical solution adopted by the present invention is: a milling device for machining the end - cover surface of a bearing, including a main body mechanism. The main body mechanism includes a chassis, and there are two clamping mechanisms for placing and clamping the bearing end - cover and a milling mechanism for batch - milling the bearing end - cover arranged on the main body mechanism.

[0004] The main body mechanism includes a lifting seat. An upper fixed disk is fixedly installed on the chassis, and a rotating frame is rotatably installed on the upper fixed disk.

[0005] The milling mechanism includes a milling column, and a plurality of milling cutters are detachably and fixedly installed on the milling column.

[0006] Furthermore, the main body mechanism further includes a rotating motor fixedly installed on the upper fixed disk. A motor gear is fixedly installed on the motor shaft of the rotating motor. A transfer gear is rotatably installed on the upper fixed disk. An internal gear ring is fixedly installed on the rotating frame. The internal gear ring meshes with the transfer gear, and the transfer gear meshes with the motor gear. A lifting electric cylinder is fixedly installed on the upper fixed disk. The output end of the lifting electric cylinder is fixedly installed with the lifting seat, and the lifting seat is slidably installed with the upper fixed disk.

[0007] The rotating motor drives the motor gear to rotate, thereby driving the internal gear ring and the rotating frame to rotate through the transfer gear. When the milling mechanism mills the inclined plane of the bearing end - cover in the clamping mechanism below it, at this time, the bearing end - cover to be machined is clamped into another clamping mechanism. After the milling mechanism finishes machining the bearing end - cover in the clamping mechanism below it, the rotating frame rotates 180 degrees to transfer the bearing end - cover to be machined below the milling mechanism, and so on.

[0008] Further, the clamping mechanism includes a clamping table fixedly installed on the rotating frame. A flipping frame is rotatably installed on the clamping table. The flipping frame is provided with a waist-shaped hole, and a frame rotation knob is arranged in the waist-shaped hole. The flipping frame is detachably connected to the clamping table through the frame rotation knob.

[0009] Further, a number of side knobs are rotatably installed on both sides of the clamping table through threads, and side pressing blocks are rotatably installed on the side knobs.

[0010] Further, a number of worm knobs and worm gear frames are rotatably installed on the flipping frame. The worm knobs are meshed with the worm gear frames, and rollers are rotatably installed on the worm gear frames.

[0011] Further, an inner table is fixedly installed inside the clamping table. Two outer inclined plane blocks are slidably installed on the inner table. The outer inclined plane blocks are provided with inclined planes. A pushing knob is rotatably installed on the flipping frame through threads. An upper inclined plane block is rotatably installed on the pushing knob. The upper inclined plane block is provided with two inclined planes. The upper inclined plane block is slidably installed with the flipping frame.

[0012] During use, unscrew the frame rotation knob, lift the flipping frame. The flipping frame rotates relative to the clamping table. Place nine bearing end caps into the clamping table. Two of the bearing end caps are located on the left side of the inner table, and seven bearing end caps are located on the right side of the inner table. Then turn down the flipping frame and fix the flipping frame on the clamping table through the frame rotation knob. Then rotate the pushing knob to drive the upper inclined plane block to descend. The upper inclined plane block pushes the two outer inclined plane blocks to slide outwards through the inclined planes, so as to push the bearing end caps through the outer inclined plane blocks, making each bearing end cap close to each other. Then twist the side knobs to drive the side pressing blocks to move inwards, and press the bearing end caps on the chassis through the side pressing blocks. Then rotate the worm knobs to drive the worm gear frames to rotate, and press the bearing end caps through the rollers, so as to realize the clamping of the bearing end caps in all directions. When milling the bearing end caps, there is mainly vertical vibration. Through the self-locking of the worm knobs and the worm gear frames, the stability of the milling process of the bearing end caps is ensured.

[0013] Further, the milling mechanism further includes a lifting table fixedly installed on the lifting seat. A lead screw motor is fixedly installed on the lifting table. A lead screw is rotatably installed on the lifting table. The lead screw is fixedly installed with the motor shaft of the lead screw motor. A sliding block is slidably installed on the lifting table. The sliding block forms a screw drive with the lead screw. A milling motor is fixedly installed on the sliding block. The motor shaft of the milling motor is fixedly installed with the milling column.

[0014] The lead screw motor rotates to drive the lead screw to rotate, thereby driving the sliding block to slide along the lifting table. The milling motor drives the milling column and the milling cutter to rotate, and the milling cutter mills the inclined planes of the nine bearing end caps on the clamping mechanism below it.

Detailed implementation manners

[0027] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0028] Example: Refer to Figures 1 - 10 , a milling device for machining the surface of a bearing end cover, including a main body mechanism. The main body mechanism includes a chassis 101. There are two clamping mechanisms for placing and clamping the bearing end cover 4 and a milling mechanism for batch milling of the bearing end cover 4 on the main body mechanism;

[0029] The main body mechanism includes a lifting seat 109. An upper fixed disk 103 is fixedly installed on the chassis 101, and a rotating frame 102 is rotatably installed on the upper fixed disk 103;

[0030] The milling mechanism includes a milling column 306, and a plurality of milling cutters 307 are detachably and fixedly installed on the milling column 306.

[0031] As Figure 2 , Figure 3 shown, the main body mechanism further includes a rotating motor 105 fixedly installed on the upper fixed disk 103. A motor gear 106 is fixedly installed on the motor shaft of the rotating motor 105. An intermediate gear 107 is rotatably installed on the upper fixed disk 103. An internal gear ring 108 is fixedly installed on the rotating frame 102. The internal gear ring 108 meshes with the intermediate gear 107, and the intermediate gear 107 meshes with the motor gear 106. A lifting electric cylinder 104 is fixedly installed on the upper fixed disk 103. The output end of the lifting electric cylinder 104 is fixedly installed with the lifting seat 109, and the lifting seat 109 is slidably installed with the upper fixed disk 103.

[0032] The rotating motor 105 drives the motor gear 106 to rotate, thereby driving the internal gear ring 108 and the rotating frame 102 to rotate through the intermediate gear 107. When the milling mechanism performs bevel milling on the bearing end cover 4 in the clamping mechanism below it, the bearing end cover 4 to be processed is clamped into another clamping mechanism at this time. After the milling mechanism finishes processing the bearing end cover 4 in the clamping mechanism below it, the rotating frame 102 rotates 180 degrees to transfer the bearing end cover 4 to be processed below the milling mechanism, and so on.

[0033] As Figures 4 - 7 shown, the clamping mechanism includes a clamping table 201 fixedly installed on the rotating frame 102. A flipping frame 202 is rotatably installed on the clamping table 201. A waist-shaped hole is provided on the flipping frame 202, and a frame rotation knob 205 is arranged in the waist-shaped hole. The flipping frame 202 is detachably connected to the clamping table 201 through the frame rotation knob 205.

[0034] As Figures 4 - 7 shown, a number of side knobs 204 are rotatably installed on both sides of the clamping table 201 through threads, and side pressing blocks 203 are rotatably installed on the side knobs 204.

[0035] As Figures 4 - 7 shown, a number of worm knobs 210 and worm gear racks 211 are rotatably installed on the flipping frame 202. The worm knobs 210 are engaged with the worm gear racks 211, and rollers 212 are rotatably installed on the worm gear racks 211.

[0036] As Figures 4 - 7 shown, an inner table 206 is fixedly installed inside the clamping table 201. Two outer bevel blocks 207 are slidably installed on the inner table 206. The outer bevel blocks 207 are provided with slopes. A pushing knob 208 is rotatably installed on the flipping frame 202 through threads, and an upper bevel block 209 is rotatably installed on the pushing knob 208. The upper bevel block 209 is provided with two slopes, and the upper bevel block 209 is slidably installed with the flipping frame 202.

[0037] During use, turn the rotary frame knob 205 to lift the flipping frame 202. The flipping frame 202 rotates relative to the clamping table 201, and nine bearing end caps 4 are placed into the clamping table 201. Two of the bearing end caps 4 are located on the left side of the inner table 206, and seven bearing end caps 4 are located on the right side of the inner table 206. Then, turn the flipping frame 202 down and fix the flipping frame 202 on the clamping table 201 through the rotary frame knob 205. Subsequently, turn the pushing knob 208 to drive the upper inclined block 209 to descend. The upper inclined block 209 pushes two outer inclined blocks 207 to slide outwards through the slope, thereby pushing the bearing end caps 4 through the outer inclined blocks 207 to make each bearing end cap 4 closely adhere to each other. Then, twist the side knob 204 to drive the side pressing block 203 to move inwards, and press the bearing end caps 4 onto the chassis 101 through the side pressing block 203. Subsequently, turn the worm knob 210 to drive the worm gear frame 211 to rotate, and press the bearing end caps 4 through the rollers 212, thereby realizing the clamping of the bearing end caps 4 in all directions. When milling the bearing end caps 4, there is mainly vertical vibration. Through the self-locking of the worm knob 210 and the worm gear frame 211, the stability of the milling process of the bearing end caps 4 is ensured.

[0038] As Figures 8 - 10 shown, the milling mechanism further includes a lifting table 301 fixedly installed on the lifting seat 109. A lead screw motor 303 is fixedly installed on the lifting table 301. A lead screw 302 is rotatably installed on the lifting table 301. The lead screw 302 is fixedly installed with the motor shaft of the lead screw motor 303. A sliding block 304 is slidably installed on the lifting table 301. The sliding block 304 forms a screw drive with the lead screw 302. A milling motor 305 is fixedly installed on the sliding block 304. The motor shaft of the milling motor 305 is fixedly installed with a milling column 306.

[0039] The rotation of the lead screw motor 303 drives the rotation of the lead screw 302, thereby driving the sliding block 304 to slide along the lifting table 301. The milling motor 305 drives the rotation of the milling column 306 and the milling cutter 307, and the milling cutter 307 performs inclined surface milling on the nine bearing end caps 4 on the clamping mechanism below it.

[0040] The working principle of a milling device for machining the bearing end cover surface disclosed in the present invention is as follows: When in use, turn the turning frame knob 205 to lift the turning frame 202. The turning frame 202 rotates relative to the clamping table 201, and nine bearing end covers 4 are placed into the clamping table 201. Among them, two bearing end covers 4 are located on the left side of the inner table 206, and seven bearing end covers 4 are located on the right side of the inner table 206. Then, turn the turning frame 202 down and fix the turning frame 202 on the clamping table 201 through the turning frame knob 205. Then, rotate the pushing knob 208 to drive the upper inclined surface block 209 to descend. The upper inclined surface block 209 pushes the two outer inclined surface blocks 207 to slide outwards through the inclined surface, so as to push the bearing end covers 4 through the outer inclined surface blocks 207, making each bearing end cover 4 close to each other. Then, twist the side knob 204 to drive the side pressing block 203 to move inwards, and press the bearing end covers 4 on the chassis 101 through the side pressing block 203. Then, rotate the worm knob 210 to drive the worm gear frame 211 to rotate, and press the bearing end covers 4 through the rollers 212, thereby realizing the clamping of the bearing end covers 4 in all directions. When milling the bearing end covers 4, there is mainly vertical vibration. Through the self-locking of the worm knob 210 and the worm gear frame 211, the stability during the milling process of the bearing end covers 4 is ensured. Rotate the driving motor 105 to drive the motor gear 106 to rotate, and then drive the internal gear ring 108 and the rotating frame 102 to rotate through the intermediate gear 107. The screw motor 303 rotates to drive the screw 302 to rotate, thereby driving the sliding block 304 to slide along the lifting table 301. The milling motor 305 drives the milling column 306 and the milling cutter 307 to rotate, and the milling cutter 307 performs inclined surface machining on the nine bearing end covers 4 on the clamping mechanism below it. When the milling mechanism performs inclined surface machining on the bearing end covers 4 in the clamping mechanism below it, at this time, the bearing end cover 4 to be machined is clamped into another clamping mechanism. When the milling mechanism finishes machining the bearing end covers 4 in the clamping mechanism below it, the rotating frame 102 rotates 180 degrees to transfer the bearing end cover 4 to be machined below the milling mechanism, and so on.
