Description

The cutter spindle latch-up structure of tire sander

Technical field

The utility model relates to a kind of latch-up structure, relates in particular to a kind of cutter spindle latch-up structure of tire sander.

Background technology

The tire sander structure of present prior art, as shown in Figure 1, but mainly be provided with the traversing platform 31 of a level toward polyslip in a support 3, be provided with a pivot block that can back and forth pivot 32 in this traversing platform 31, one cutter drives motor 4 is located on this traversing platform 31, the power output shaft of this cutter drives motor 4 is in conjunction with a driving wheel 41, this driving wheel 41 is connected assembly 42 (belt) via one and is connected a driven pulley 43, and this driven pulley 43 is connected in a reconditioning cutter 5 through a change gear box 51 with a cutter spindle 52, and is provided with the outer cover 53 of a tool chip discharging tube 531 in these reconditioning cutter 5 peripheries; One support 33 is located at this support 3 sides, is provided with a tire CD-ROM drive motor 6 in this support 33, and this tire CD-ROM drive motor 6 can drive a wheel rim main shaft 72 that combines with wheel rim 7 via a reduction gear box 71.

During operation, tire to be grinding is sleeved on wheel rim 7 peripheries and inflation is expanded its, utilizing this tire CD-ROM drive motor 6 to drive this wheel rim main shaft 72 via reduction gear box 71 rotates, this tire to be grinding is produced synchronously in wheel rim main shaft 72 peripheries to rotate, simultaneously, cutter drives motor 4 is via being connected this cutter spindle 52 of assembly 42 interlocks, can make reconditioning cutter 5 produce high speed rotating, cooperate the slippage of this traversing platform 31 and the rotation of pivot block 32, make this reconditioning cutter 5 can form the slippage of a suitable radian in this tire periphery to be grinding, using this tire periphery of reconditioning makes it smooth, be beneficial to follow-up glue or the repairing work of covering, the chip that the reconditioning tire is produced then can be discharged by the chip discharging tube 531 of outer cover 53; Yet, in the said structure, its reconditioning cutter 5 is via change gear box 51 and cutter spindle 52 interlocks, this cutter spindle 52 is then via driven pulley 43, be connected assembly 42 and be connected with the driving wheel 41 of cutter drives motor 4, because this reconditioning cutter more than 5 pivots with nut and is packed in the output shaft of change gear box 51, described output shaft and cutter spindle 52 synchronous interlocks, and there is no any latch-up structure in the associated junction structure of this cutter drives motor 4 and cutter spindle 52, therefore this reconditioning cutter 5 can freely pivot under the nature that is not subjected to external force, thus, whenever maintenance maybe need be changed reconditioning cutter 5 and during the assembly of desire dismounting locking cutter, this reconditioning cutter 5 is easy to produce the rotation of non-expectation, have a strong impact on the carrying out of above-mentioned field-strip, so, more common situation is at present, the operator must be directly or indirectly to fix this reconditioning cutter 5 by aid on the other hand, to avoid it in aforesaid operations, to rotate, dismantle this locked assembly with another handheld tool again, so mode of operation not only causes greatly inconvenience and puzzlement in the operation, also influences the efficient and the quality of maintenance activity.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As shown in Figure 1, be the tire sharpening machine structure of prior art, its main composition with and disappearance, as previously mentioned, repeated description no longer herein.

Fig. 2 is a D structure schematic diagram of the present utility model, simultaneously with reference to Fig. 3, each plan view of 4, can clearly find out, the utility model is mainly based on the structure of aforementioned Fig. 1, its main difference is: a cutter spindle 54 is located in the change gear box 51, its end stretches out and combines with driven pulley 43, on this cutter spindle 54, at least be provided with a detent 541, this detent 541 can (can be parallel surface by having at least one flat bevel on pattern, non-parallel face, square, regular hexagon, octagon .... wait the axial section of positive plural polygon) shaft part form, all the other supports 3, cutter drives motor 4, reconditioning cutter 5, tire CD-ROM drive motor 6 and wheel rim 7 wait each main position and dependency structure thereof, and then the structure with earlier figures 1 is identical; Other has a locking tool 1 to be located near detent 541 places; In implementing illustration, this is arranged on two parallel flat bevels of 43 of aforesaid driving wheels 41, driven pulley, be provided with a dog point 11 in its end towards detent 541, be an end notches in graphic, be provided with relative detent 541 and the flat chamfered edge established in this dog point 11; One locking tool driven unit, 2 (can be a pneumatic cylinder) connection is located at this locking tool 1, it can be connected combination with this locking tool 1 by a drive rod 21, and in being provided with the guide rod 22 default guide hole on the guide sliding base 23 respectively that is parallel to drive rod 21 on this locking tool 1 in addition, drive this positioning fixture 1 slippage by this locking tool driven unit 2 with drive rod 21, cooperate the guiding reconditioning cutter of these guide rods 22 can make the dog point 11 of locking tool 1 produce stable effect with respect to cutter spindle 54 displacement effects;

Fig. 5,6 respectively moves schematic diagram for locking tool of the present utility model, shown in this two figure, when the drive rod 21 of this locking tool driven unit 2 extends, the dog point 11 of locking tool 1 discharges detent 541 away from cutter spindle 54, the driving wheel 41 of cutter drives motor 4 can be via being connected assembly 42 (belt) interlock driven pulley 43 at this moment, but make these cutter spindle that combines with driven pulley 43 54 gang speed-variation gear-boxes 51 and drive reconditioning cutter 5 high speed rotating, so that carry out reconditioning operation (action of all the other each structures, it is described then to please refer to earlier figures 1); And use when wearing and tearing because of permanent when 5, this cutter drives motor 4 is shut down, and the drive rod 21 of locking tool driven unit 2 shrinks, but the dog point 11 convergence systems that make this locking tool 1 are placed in the detent 541 of cutter spindle 54, utilize the relatively flat bevel of the flat chamfered edge clip of dog point 11 in cutter spindle 54, can keep within bounds this cutter spindle 54, make and to rotate, 5 on this reconditioning cutter forms location (can't the pivot) effect identical with cutter spindle 54 via the linking of change gear box 51, so that change the maintenance activity of reconditioning cutter 5.
