Abstract
The utility model discloses a special detaching tool for a hinge pin with a threaded hole. The special detaching tool comprises a threaded rod, a supporting base, an adjusting cushioning cylinder and a threaded sleeve. The supporting base, the adjusting cushioning cylinder and the threaded sleeve are installed on the threaded rod in a sleeved mode. External threads are arranged at one end of the threaded rod and matched with the threaded hole. The threaded sleeve is in threaded connection with the threaded rod. Compared with an existing detaching tool, the threaded rod and nut structure is adopted, acting force and reactive force are utilized, people only need to rotate the threaded sleeve to take out the hinge pin with the threaded hole from a narrow space easily, in this way, labor intensity is relieved, labor efficiency is improved, and the steel plate pin is prevented from damage caused by brute-force detaching.
Description
Technical field
The utility model relates to a kind of extracting tool, relates in particular to a kind of removal tool special with screw bearing pin.
Background technology
At present present assembling and engineering repair works dismantle the connecting pin of the leaf springs such as existing automobile, mostly adopt machinery to impact rough power dismounting, and labour intensity is large, also large to the damage of steel plate pin.
Present passenger vehicle is more and more pursued comfortableness and security.This just requires the barycenter of passenger vehicle more and more lower, and passenger vehicle is from high-low plate to low entrance with low-floor transition.Like this, under passenger-carrying chassis, the space of parts is more and more less.For example, bearing before city bus rear spring, squeezes between rear guard and middle visitor's door, and upper and lower space, front and back all only has narrow 200mm left and right.Steel plate pin wants left and right to split out, the space of at all not exerting oneself, and hammer cannot be thrown away with strength.
Utility model content
The problem existing for above-mentioned prior art, the utility model object is to provide a kind of bolt and nut structure that adopts, and utilizes active force and reaction force, at narrow space, takes out the removal tool special with screw bearing pin.
The technical solution of the utility model is: a kind of removal tool special with screw bearing pin, comprise screw rod, supporting seat, spacer cylinder and swivel nut, described supporting seat, spacer cylinder, swivel nut are set on screw rod successively, described screw rod one end is provided with the external screw thread matching with screw, and described swivel nut is connected with screw flight;
As preferably, described spacer cylinder is fixedly connected with swivel nut, described supporting seat and the clamping of spacer cylinder;
As preferably, described spacer cylinder is stretching structures for multiple pad cylinder compositions;
As preferably, the square that described bolt head is standard specification or hexagon;
As preferably, described swivel nut head is six side's outer nut shapes.
The beneficial effects of the utility model are: adopt bolt and nut structure, utilize active force and reaction force, only need to rotate swivel nut, just can easily take out in narrow space band screw bearing pin, alleviate labour intensity, improved efficiency, avoided rough power dismounting to cause damage to steel plate pin.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1. screw rod; 2. supporting seat; 3. spacer cylinder; 4. swivel nut.
The specific embodiment
Embodiment: as a kind of embodiment of the present utility model, a kind of removal tool special with screw bearing pin as shown in Figure 1, comprise screw rod 1, supporting seat 2, spacer cylinder 3 and swivel nut 4, described supporting seat 2, spacer cylinder 3, swivel nut 4 is set on screw rod 1 successively, described spacer cylinder 3 is fixedly connected with swivel nut 4, described supporting seat 2 and 3 clampings of spacer cylinder, described spacer cylinder 3 is the stretching structure of multiple pad cylinder compositions, be equivalent to extension bar, bearing pin (as the automobile steel plate spring pin) dismounting that can be used for growing, described swivel nut 4 is threaded with screw rod 1, described swivel nut 4 heads are six side's outer nut shapes, convenient with spanner rotation swivel nut 4.
Utilize the screw thread of the fuel filler neck of spring piot, be connected with the bolt head of the utility model screw rod 1, withstand leaf spring bearing with supporting seat 2, rotation swivel nut 4, supporting seat 2 and swivel nut 4 are axially motionless, screw rod 1 drives steel plate pin to move outward under the reaction force of swivel nut 4, and so repeatedly, steel plate pin has just been pulled out.
The relation of the pretightning force F of screw thread and screw-down torque M can simply be denoted as T=0.2 × F × d, the diameter that d is screw thread.
According to active force and reaction force principle, the pretightning force F=5 × T/d of the pulling capacity=screw rod 1 of bearing pin.
We know, the diameter of general bearing pin screw thread only has Centimeter Level unit (the screw 10-20mm of steel plate pin), a unskilled labour active force of strength by arm in 10kgf, and pulling capacity has just been exaggerated hundreds of times.Like this, drawing bearing pin is just easier.
Above a kind of removal tool special with screw bearing pin provided by the utility model has been carried out to detailed introduction, applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, to change of the present utility model and improvement, will be possible, and can not exceed design and the scope of accessory claim defined, in sum, this description should not be construed as restriction of the present utility model.
Claims (5)
1. the removal tool special with screw bearing pin, it is characterized in that: comprise screw rod, supporting seat, spacer cylinder and swivel nut, described supporting seat, spacer cylinder, swivel nut are set on screw rod successively, described screw rod one end is provided with the external screw thread matching with screw, and described swivel nut is connected with screw flight.
2. a kind of removal tool special with screw bearing pin according to claim 1, its feature is being: described spacer cylinder is fixedly connected with swivel nut, described supporting seat and the clamping of spacer cylinder.
