Abstract
The utility model discloses a double-end stud assembling tool, comprising a tool body. A screwed hole is axially arranged at the lower end of the tool body upwards, and the problems that the traditional tooling is easy to wear, a double-end stud is easy to loose along with the loosing of the tooling and the labor intensity is high are solved. In the utility model, the backing phenomenon of the double-end stud can be prevented, the assembly of the double-end stud can be rapidly realized, the assembling efficiency is high, the labor intensity is obviously reduced, and the double-end stud assembling tool is indispensable for mechanical assembly.
Description
Technical field
The utility model relates to a kind of machine-building instrument, specifically is a kind of studs assembly tool.
Background technology
What the assembling of faying faces connection studs such as compressor crank shaft casing, cylinder block was adopted in the past is geotechnique's dress, at first with two spanners two nuts be added on the bolt, and tight, then the bottom nut is screwed into studs to be assembled one end, makes bottom nut spiral shell and connecting bolt and studs; Twisting two nut rotation drive studs with two spanners and assembling, after studs is fastening, is unclamping nut fast, take off frock with spanner again, the assembling action of studs is finished.The problem that the method for geotechnique dress exists is that two nuts are stressed repeatedly, fragile, studs also the time regular meeting unclamp and become flexible along with frock, and the method labour intensity is big, inefficiency.
The utility model content
The technical problems to be solved in the utility model provides a kind of studs assembly tool, solves that traditional geotechnological holding tool is easy to wear, studs unclamps along with frock and loosening and the big problem of labour intensity.
The technical solution of the utility model is:
A kind of studs assembly tool comprises body of tool, boosting-rod, and the lower end of described body of tool axially upwards has screwed hole.
The top of described screwed hole has locating hole, and the aperture of locating hole is greater than the aperture of screwed hole, and is interconnected with screwed hole; The top of described locating hole is provided with the upper surface.
The top of described screwed hole has installing hole, and the aperture of installing hole is less than the aperture of screwed hole, and is interconnected with screwed hole.
The screw thread of described screwed hole and the threads engaged on the studs.
The top of described locating hole has installing hole, and the aperture of installing hole is less than the aperture of locating hole, and is interconnected with locating hole.
In the described installing hole ejector pin is installed, the bottom of ejector pin is goed deep in the screwed hole.
In the described installing hole ejector pin is installed, the bottom of ejector pin is goed deep in the locating hole.
Operation principle of the present utility model is: an end of studs to be assembled is screwed in the screw of machinery to be assembled, the other end of studs is screwed in the screwed hole of body of tool, top with body of tool is screwed in the draw-in groove of boosting-rod then, both hands rotation boosting-rod drives studs and is screwed in the screw of machinery to be assembled, the fastening back counter-rotating of studs boosting-rod, body of tool screws down from studs, finishes the studs assembling.
The aperture of locating hole described in the utility model is greater than the aperture of screwed hole, and the top of locating hole is equipped with ejector pin, guaranteed that the top of studs can be not stuck in screwed hole, reduced the frictional force of studs and screwed hole.
The utility model is compared with traditional assembly tool, has the following advantages:
1, efficiency of assembling improves, and shortens the production cycle, reduces cost;
2, safe in process is reliable;
3, simple, convenient;
4, instrument simplicity of design, the recycling rate of waterused height;
5, guarantee product quality, operative employee's technical ability is required also to reduce greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the installation diagram of the used studs of crankcase.
Fig. 3 is the installation diagram of the used studs of cylinder block.
The specific embodiment
A kind of studs assembly tool (see figure 1), comprise body of tool 1, boosting-rod 2, the lower end of body of tool 1 axially upwards has screwed hole 3, and the top of screwed hole 3 has locating hole 4, the aperture of locating hole 4 is greater than the aperture of screwed hole 3, and is interconnected with screwed hole 3; The top of locating hole 4 has installing hole, and installing hole and locating hole 4 are interconnected, and ejector pin 5 is installed in the installing hole, and the bottom of ejector pin 5 is goed deep in the locating hole 4.
The assembling (see figure 2) of the used studs of crankcase a: end of studs to be assembled 6 is screwed in the screw of crankcase 7, the other end of studs 6 is screwed in the screwed hole 3 of body of tool 1, top with body of tool 1 is screwed in the draw-in groove of boosting-rod 2 then, both hands rotation boosting-rod 2 drives studs 6 and is screwed in the screw of crankcase 7, studs 6 fastening back counter-rotating boosting-rods 2, body of tool 1 screws down from studs 6, finish the assembling of studs 6, studs 6 can not unclamp and unclamps with assembly tool when assembly tool unclamped.
The assembling (see figure 3) of the used studs of cylinder block a: end of studs to be assembled 6 is screwed in the screw of cylinder block 8, the other end of studs 6 is screwed in the screwed hole 3 of body of tool 1, top with body of tool 1 is screwed in the draw-in groove of boosting-rod 2 then, both hands rotation boosting-rod 2 drives studs 6 and is screwed in the screw of cylinder block 8, studs 6 fastening back counter-rotating boosting-rods 2, body of tool 1 screws down from studs 6, finish the assembling of studs 6, studs 6 can not unclamp and unclamps with assembly tool when assembly tool unclamped.
The utility model can prevent the setback of studs, can realize the assembling of studs simultaneously faster, the efficiency of assembling height, and labour intensity obviously reduces, and is the indispensable instrument of machinery assembling.
