The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figures 1 to 6; the utility model comprises outer baffle 1 and interior arm-tie 2 for the assembly that cavity structure with holes is carried out to closed protective in ball blast technique; outer baffle 1 comprises circular slab 1-1, manual nut 1-2, adjusts pad 1-3, three limited block 1-4 and O-ring seal 1-5; circular slab 1-1 center is provided with manhole 1-1-1; manual nut 1-2 is T-shaped structure, and its inside, lower end is provided with screwed hole 1-2-1.Adjust pad 1-3 between circular slab 1-1 and manual nut 1-2, the center of adjusting pad 1-3 is provided with through hole, and this through hole and manhole 1-1-1 are staggered relatively.Three limited block 1-4 are 120 ° of uniform weldings each other on the inner surface circumference of circular slab 1-1, and O-ring seal 1-5 sticks on the inner surface circumference of circular slab 1-1, and is enclosed within the periphery that three limited block 1-4 form.Under unassembled state, circular slab 1-1, manual nut 1-2 and adjustment pad 1-3 are in state separated from one another.
Interior arm-tie 2 comprises rectangular slab 2-1, screw rod 2-2 and screw 2-3, and rectangular slab 2-1 upper end is provided with screw hole, and this screw hole hole heart equates apart from the distance at the distance at rectangular slab 2-1 center and the centre-to-centre spacing circular slab 1-1 center of three limited block 1-4.Screw 2-3 welds through this screw hole and with rectangular slab 2-1, and screw rod 2-2 is weldingly fixed on the center of rectangular slab 2-1.The equal diameters of the length of rectangular slab 2-1 and circular slab 1-1.
As shown in Figure 7, on the right side wall with the workpiece 3 of cavity, there is a unthreaded hole that needs shutoff protection.Concrete application the utility model, for when ball blast technique is carried out the assembly of closed protective to cavity structure with holes, selects the slightly larger in diameter of circular slab 1-1 in the ball blast protection assembly for the treatment of shutoff unthreaded hole diameter.
First, interior arm-tie 2, along treating that the unthreaded hole of shutoff puts into the inside of cavity workpiece 3, is then vertically placed rectangular slab 2-1, grasped screw rod 2-2 and it is extracted from unthreaded hole, make screw rod 2-2 and unthreaded hole coaxial, and the upper/lower terminal of rectangular slab 2-1 is adjacent to unthreaded hole madial wall respectively.After this, with tool tong, replace and holding, clamp the root of screw rod 2-2, and keep its invariant position with respect to unthreaded hole.
Circular slab 1-1 is enclosed within to screw rod 2-2 by manhole 1-1-1 upper, and three limited block 1-4 is placed among the unthreaded hole inwall of cavity workpiece 3.In turn adjustment pad 1-3 and manual nut 1-2 are enclosed within to screw rod 2-2 above again, and rotate manual nut 1-2 by hand, manual nut 1-2 is threaded with screw rod 2-2 by screwed hole 1-2-1.
In the process of hand rotary manual nut 1-2, screw rod 2-2 can rotate under the moment of torsion of frictional force drives together with rectangular slab 2-1, until the screw 2-3 on rectangular slab 2-1 is blocked by any one the limited block 1-4 on outer baffle 1.Along with manual nut 1-2 is tight with being threaded of screw rod 2-2, adjustment pad 1-3 between circular slab 1-1 and manual nut 1-2 is compressed gradually, simultaneously, the unthreaded hole both sides of cavity workpiece 3 are also clamped by circular slab 1-1 and rectangular slab 2-1 respectively, and O-ring seal 1-5 is also adjacent to the unthreaded hole outer wall of cavity workpiece 3.When manual nut 1-2 will be torqued-up to tool tong and be stepped up, taking off tool pincers, change into and lift circular slab 1-1 with hand rest.Until this ball blast protection assembly is locked the wallboard of the unthreaded hole both sides of cavity workpiece 3 under the effect of stiction; in the time of cannot coming off; hand is removed from the below of circular slab 1-1, completed the ball blast shutoff protection process that rail vehicle truck enclosed cavity parts is exposed to circular hole.
