The utility model provides a spindle dish mounting structure.
Referring to fig. 1 to 6, the spindle disk mounting structure includes a support 100, a driving mechanism and a fixing mechanism; the driving mechanism comprises a power device 210, a driving gear 220, a spindle shaft 230 and a driven gear 240; wherein, the driving gear 220 is fixed with the output shaft of the power device 210; one end of the spindle shaft 230 is rotatably installed in the limit hole of the support 100, and the side wall of the spindle shaft 230 is used for connecting the outer spindle disc 400; a mounting hole is formed in the center of the driven gear 240, the mounting hole is fixedly sleeved on the spindle shaft 230, and the driven gear 240 is meshed with the driving gear 220; the securing mechanism includes a snap ring 310; a snap ring 310 is installed at one end of the spindle shaft 230 far from the support 100, and a side of the snap ring 310 near the driven gear 240 is provided with a pin shaft 311, and the pin shaft 311 is detachably inserted into a pin hole on the outer spindle disk 400.
The technical scheme of the utility model among, because spindle shaft 230 and driven gear 240 fixed connection, spindle shaft 230 follows driven gear 240 rotatoryly, snap ring 310 and spindle shaft 230 fixed connection simultaneously to snap ring 310 follows spindle shaft 230 rotatoryly. And because the pin shaft 311 is provided on the snap ring 310 and the pin shaft 311 is inserted into the pin hole on the outer spindle disk 400, the outer spindle disk 400 will rotate following the snap ring 310. Compared with the traditional spindle disk mounting structure, the spindle disk mounting structure of the scheme does not need to consider the position relation between the pin hole and the pin shaft 311 when the external spindle disk 400 is mounted, and the pin shaft 311 only needs to be inserted into the pin hole when the clamping ring 310 is mounted. The snap ring 310 is small, lightweight, and easy to rotate relative to the outer spindle disk 400, thus allowing for easier installation. Moreover, because the spindle shaft 230 and the outer spindle disk 400 rotate along with the driven gear 240, the outer spindle disk 400 is static relative to the spindle shaft 230, and does not move relative to the spindle shaft 230, so that the friction resistance does not need to be overcome to do work, the energy is saved, the friction temperature rise is avoided, and the situation that the spindle shaft 230 is abraded is avoided.
Specifically, the spindle shaft 230 is formed with a set of first keyways; the clamping ring 310 extends along the peripheral wall to the central axis direction to form a group of limiting grooves, and the number and the positions of the limiting grooves correspond to those of the first key grooves; each limiting groove is provided with a limiting block 312, the cross section of each limiting block 312 is L-shaped, and a thimble 313 is connected in each limiting block 312 through a spring; one end of the thimble 313 far away from the limit block 312 is connected with a moving block 314, the moving block 314 is slidably mounted in the limit groove, and one end of the moving block 314 far away from the thimble 313 is detachably inserted into the first key groove of the spindle shaft 230. The spring in the limit block 312 pushes the thimble 313, the thimble 313 pushes the moving block 314 to move towards the inner part 310 of the snap ring, and one end of the moving block 314 far from the thimble 313 is gradually inserted into the first keyway of the spindle shaft 230, so that the snap ring 310 and the spindle shaft 230 are connected into a whole. The connection mode can be realized through the elasticity of the spring, and the operation is more convenient.
In an embodiment of the present invention, a wedge 315 is formed on a side of the moving block 314 away from the driven gear 240; the securing mechanism further includes a disassembly block 320; the disassembling block 320 is in a circular truncated cone shape, and a through hole is formed along the central shaft of the disassembling block 320; the detaching block 320 is slidably fitted over the spindle shaft 230. When the outer spindle plate 400 needs to be removed, the dismounting block 320 is only pushed to the clamping ring 310, and in the process that the dismounting block 320 moves towards the clamping ring 310, the inclined surface of the dismounting block 320 jacks up the wedge-shaped table 315 towards the outer side of the clamping ring 310, so that the moving block 314 is gradually pulled out of the first key groove, and the clamping ring 310 is disconnected from the spindle shaft 230. Snap ring 310 and outer spindle disk 400 may then be sequentially removed from spindle shaft 230. Compared with the traditional spring bolt structure, the structure is more convenient to operate and saves labor.
Specifically, a bearing 110 is disposed in the limiting hole of the support 100, an outer ring of the bearing 110 is fixed to the support 100, and an inner ring of the bearing 110 is fixed to the spindle shaft 230. By arranging the set of bearings 110, the friction force between the spindle shaft 230 and the support 100 can be effectively reduced, and the spindle shaft 230 is protected from abrasion.
Preferably, the driven gear 240 is connected with the spindle shaft 230 by a flat key. The spindle shaft 230, which is connected to the driven gear 240 by a flat key, is more convenient to remove for repair or replacement than a fixed connection.
Preferably, the number of the first key grooves on the spindle shaft 230 is not less than two, and the first key grooves are uniformly distributed along the circumferential direction of the spindle shaft 230. The at least two first key slots can more firmly connect the snap ring 310 and the spindle shaft 230, so as to avoid slipping in the working process.
Preferably, the number of the bearings 110 is not less than two. The bearing 110 with no less than two sets can optimize the stress of the spindle shaft 230 in the support 100, so that the spindle shaft 230 rotates more smoothly.
Preferably, the stop block 312 is bolted to the snap ring 310. The connection mode is simple to operate, and the limiting block 312, the thimble 313 or the moving block 314 can be conveniently detached for overhaul or replacement. The support 100 is connected with an external mechanism; the limiting holes on the support 100 are arranged along the horizontal direction, so that the outer spindle plate 400 is easier to mount.
