Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of the utility model swivel joint;
Fig. 4 is the structural representation of the utility model transit joint.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of stud mounting tool as shown in Figure 1 and Figure 2, comprise the joint for connecting stud and pneumatic impact wrench, joint comprises the swivel joint 1 connected with stud and the transit joint 2 connected with pneumatic impact wrench rifle head, swivel joint 1 and transit joint 2 pass through thread connection, and between swivel joint 1 with transit joint 2, being provided with the alignment pin 3 both being radially connected, the rotation that alignment pin can realize transit joint and swivel joint links.
Further, as shown in Figure 3, the inside, front end of swivel joint 1 is provided with the first internal thread segment 11 matched with stud external screw thread, the inside, rear end of swivel joint 1 is provided with the second internal thread segment 12 matched with transit joint 2, second internal thread segment 12 is radially provided with the first pin-and-hole 13 matched with alignment pin 3, first pin-and-hole 13 is mounting hole, and the diameter of the first pin-and-hole 13 and the diameter of alignment pin 3 match.First pin-and-hole 13 adopts mounting hole, can provide the buffering of one section of rotary distance when rotated.
Further, as shown in Figure 4, transit joint 2 comprises the first cylindrical section 21 matched with swivel joint 1 and the second cylindrical section 22 matched with pneumatic impact wrench rifle head and the transition round platform 23 connecting first, second cylindrical section 21,22.
Further, the outer surface of the first cylindrical section 21 is provided with the external screw thread matched with the second internal thread segment 12, and the first cylindrical section 21 is radially provided with the second pin-and-hole 211 matched with alignment pin 3, second pin-and-hole 211 is manhole, and the diameter of the second pin-and-hole 211 and the diameter of alignment pin 3 match.
Further, the center of the first cylindrical section 21 end is inwardly provided with the blind hole 212 of band cone angle, and be placed with steel ball 4 in blind hole 212, the diameter of steel ball 4 is greater than the degree of depth of blind hole 212, and after stud connects with swivel joint 1, between the end of stud and steel ball 4, form point cantact; When point cantact can reduce rotation, the frictional force of stud end face, effectively reduces the impact of pneumatic impact wrench inverse time on stud screw-down torque.
Further, the end of the second cylindrical section 22 is inwardly provided with the endoporus 221 matched with pneumatic impact wrench rifle head vertically, and endoporus 221 is provided with the aperture 222 corresponding with the clamping steel ball of pneumatic impact wrench rifle head diametrically.
Concrete using method is as follows:
First transit joint is passed through together with thread connection with swivel joint, and insert alignment pin; Again steel ball is put into the blind hole of the band cone angle of transit joint front end from the front opening of swivel joint, be screwed in swivel joint until the end face of stud abuts to steel ball needing the stud installed, the other end of transit joint is connected with pneumatic impact wrench, again stud installation end is aimed at installing hole and start pneumatic impact wrench, stud is screwed in screwed hole, rear reversion pneumatic impact wrench tightened by stud, and frock is separated with stud.
In sum, the utility model is by connecting stud with swivel joint, swivel joint is connected with transit joint and is realized the interlock that rotates by alignment pin, transit joint connects with pneumatic impact wrench rifle head again, is realized the installation of stud, after installation by the rotating forward of pneumatic impact wrench, during pneumatic impact wrench reversion, alignment pin makes transit joint reverse together with swivel joint, because the first pin-and-hole on swivel joint is mounting hole, can provide the buffering of one section of rotary distance; Simultaneously stud is when connecting with swivel bolt, and the end face of stud and the steel ball of transit joint realize point cantact, the frictional force of stud end face during to reduce rotation.Whole tool structure is simple, easy to use, effectively can reduce the impact of pneumatic impact wrench reversion on stud screw-down torque, ensure that screw-down torque when stud is installed.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
