Abstract
The utility model relates to a pulling tool for an internal-thread taper pin, which comprises a pulling rod, a holding part and a pull head, wherein threads are arranged on at least one end of the pull head, the pull head is connected with the taper pin through the threads, and the other end of the pull head is connected with the bottom of the pulling rod. According to specifications of taper pins needing to be pulled, pull heads of different specifications are provided. The holding part is sleeved on the pulling rod to slide in a reciprocating mode, and the top of the pulling rod is provided with a limited block for limiting the continuous sliding of the holding part. In use, the limited block is hit by the holding part, and the internal-thread taper pin is pulled through inertia force. With the structure, the pulling tool enables various internal-thread taper pins to be disassembled conveniently and quickly, is easy in operation, has reliable performance, and is particularly suitable for the disassembling of mass internal-thread taper pins.
Description
Technical field
The utility model belongs to the technical field of hardware ﹠ tools, and specifically, the utility model relates to a kind of taper pin with internal thread pulling tool.
Background technology
Taper bolt is a securing member commonly used in the machine-building, generally cooperates with bolt to be used for being connected of two parts.After the faying face that it is vertically mounted on two parts is close to together in the taper hole of strand system.Because taper bolt and taper hole can be realized not having the gap and cooperate, institute is so that the relative position of two parts obtains unique fixing.Ressemble after the dismounting, can recover the fixing relative position of two parts exactly by taper bolt.The dismounting of taper bolt generally is it to be launched from its segment with the cylinder instrument, for the taper bolt that is contained in obstructed conical bore or can't launch from its small end by design of part restriction, just adopt taper pin with internal thread, the big end of this taper bolt has screwed hole, taper bolt is pulled out by screwed hole with corresponding bolts and backing plate.But there are some problems in this method: 1, the concrete structure according to two part combinations will be equipped with corresponding bolts and backing plate, and the instrument of rotating bolt; 2, because the reach of taper pin with internal thread is limited, the diameter of thread is less, and screw thread may be damaged in unloading process; 3, the take-down time is slower, incompatible than the dismounting of taper pin with internal thread in enormous quantities.
The utility model content
Technical problem to be solved in the utility model provides a kind of taper pin with internal thread pulling tool, dismantles taper pin with internal thread easily and fast.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of taper pin with internal thread pulling tool, and it has comprised dead man, grip part and pull head; Described pull head at least at one end is provided with screw thread, and by the described taper bolt that is threaded, its other end connects the bottom of described dead man, according to the specification that will work the taper bolt that pulls out, is equipped with the pull head of different size; Described grip part is socketed on described the dead man and reciprocatingly slides, and is provided with the limited block that slip is continued in the described grip part of restriction at the top of described dead man; During use, grip part bump limited block utilizes inertia force to rise and pulls out taper pin with internal thread.
Described grip part is a rotary structure, and the diameter at its both ends is greater than the diameter at its middle part.
By being threaded, be provided with screwed hole between described pull head and described the dead man in the bottom of described dead man, corresponding described pull head with play the position that dead man is connected and be provided with screw thread.
Also being provided with a limited block described dead man upper bottom portion, slides in zone between described two limited blocks, described grip part.
Advantage of the present utility model is to adopt this kind structure, specification according to taper pin with internal thread is equipped with corresponding pull head, during use, grip part bump limited block, utilize inertia force to rise to pull out taper pin with internal thread, the multiple taper pin with internal thread of dismounting that can be easily and fast, simple to operate, dependable performance is particularly suitable for the dismounting of taper pin with internal thread in enormous quantities.
Description of drawings
Fig. 1 is the utility model structural representation;
Mark among the above-mentioned figure is: 1, grip part; 2, play dead man; 3, pull head; 4, limited block.
The specific embodiment
Contrast accompanying drawing below,, the specific embodiment of the present utility model is described in further detail by description to embodiment.
As shown in Figure 1, a kind of taper pin with internal thread pulling tool of the utility model, it has comprised dead man 2, grip part 1 and pull head 3; This pull head 3 at least at one end is provided with screw thread, and by the described taper bolt that is threaded, its other end connects the bottom of described dead man 2, according to the specification that will work the taper bolt that pulls out, is equipped with the pull head 3 of different size; Grip part 1 has been socketed on the dead man 2 and has reciprocatingly slided, and is provided with the described grip part 1 of restriction at the top of playing dead man 2 and continues the upwards limited block 4 of slip; During use, grip part 1 this limited block 4 of bump utilizes inertia force to rise and pulls out taper pin with internal thread.
And this grip part 1 is rotary structure, and the diameter at its both ends is convenient to grip greater than the diameter at its middle part like this, prevents in use grip part 1 slippage from hand.
Pull head 3 with rise between the dead man 2 by being threaded, be provided with screwed hole in the bottom of playing dead man 2, corresponding pull head 3 be provided with screw thread with playing the position that dead man 2 is connected, by being threaded, make things convenient for the switching of pull head 3.
Also being provided with a limited block 4 in dead man 2 upper bottom portion, slides in zone between two limited blocks 4, grip part 1.
The utility model adopts said structure, specification according to taper pin with internal thread is equipped with corresponding pull head 3, during use, grip part 1 bump limited block 4, utilize inertia force to rise to pull out taper pin with internal thread, the multiple taper pin with internal thread of dismounting that can be easily and fast, simple to operate, dependable performance is particularly suitable for the dismounting of taper pin with internal thread in enormous quantities.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
