Detailed Description

The invention is further described below with reference to the accompanying drawings:

as shown in fig. 1 to 3, a jig for quickly disassembling a chuck comprises a first mounting bracket 1, a second mounting bracket 2, a bottom support rod 3, a guide rod 4, a telescopic motor 5, a pressure head 6, a sliding block 7, a push rod 8 and a sliding plate 9, wherein the first mounting bracket 1 and the second mounting bracket 2 are arranged left and right, two ends of the bottom support rod 3 are respectively fixed on the first mounting bracket 1 and the second mounting bracket 2, two ends of the guide rod 4 are respectively fixed on the first mounting bracket 1 and the second mounting bracket 2, the guide rod 4 is provided with two sets and corresponds to the front side and the rear side of the upper part of the bottom support rod 3, the telescopic motor 5 is fixed at the right end of the first mounting bracket 1 and corresponds to the upper part of the guide rod 4, the sliding block 7 is slidably connected with the two sets of guide rods 4, a pressing block is fixed at the power output end of the telescopic motor 5 and corresponds to the left side of the sliding block 7, the left end of the push rod 8 is fixed at the right side of the sliding block 7, the lower end of the sliding plate 9 is slidably connected with the two sets of the guide rods 4, a guide groove 91 is arranged at the upper end of the sliding plate 9, the guide groove 91 corresponding to the lower end of the push rod 8, a vertical groove 21 is arranged on the second mounting bracket 2 corresponding to the push rod 8.

Dismantle the messenger at the epaxial chuck of needs pairing rotation, place the main shaft on slide 9, slide 9 can slide on guide arm 4, slide 9's position can carry out position adjustment according to the length of main shaft, the chuck is corresponding to vertical recess 21, the right-hand member of main shaft and the 2 tops of second installing support touch, under the drive of flexible motor 5, the briquetting drives slider 7 and ejector pin 8 right, ejector pin 8 stretches into in the main shaft and releases the chuck right and pass vertical recess 21, thereby realize the quick dismantlement of chuck, diameter size and central shaft position according to the rotating spindle, can choose not unidimensional slider 7 and ejector pin 8 for use, ensure that ejector pin 8 wears to establish in the rotating spindle.

In this design, still include the lantern ring 10, the lantern ring 10 sets up the left side at vertical recess 21, to the less rotating main shaft of some outside diameters, its external diameter is still little than vertical recess 21's width even, at this moment, can't touch rotating main shaft's right-hand member top on second installing support 2, consequently, adopt lantern ring 10 cover to establish rotating main shaft's right-hand member, the edge through the lantern ring 10 touches with 2 tops of second installing support, thereby when dismantling the chuck, rotating main shaft can not wear to establish vertical recess 21, rotating main shaft can normally fix in 2 left sides of second installing support, so that realize the dismantlement of chuck.
