Abstract
The utility model discloses a tool used for disassembling an oil pump testing taper sleeve. The tool comprises a taper sleeve (1) and a tip cone (3), the taper sleeve (1) is provided with an internal thread stepped hole, a connection seat (2) is in screw joint with a shaft through the internal thread stepped hole, the tip cone (3) passes through a central threaded hole of the connection seat (2) and falls into the stepped hole of the taper sleeve (1), a torque acts on the tip cone (3), and the tip core falls off through axial movement pressure pressing against a cam shaft and generated by screw of a screw thread pair of the tip cone (3). By using the tool provided by the utility model, the oil pump testing taper sleeve can be disassembled in a labor-saving, rapid and safe manner, the attrition rate of the tool is extremely low, the operation efficiency is raised by over 50%, the service life is raised by one time, and accidents such as three-jaw puller bounce and taper sleeve flying do not occur.
Description
Technical field
The utility model relates to a kind of frock for dismounting oil pump test tapered sleeve, especially for removing and installing the tapered sleeve that is used for connecting oil pump test stand shaft coupling in fuel injection camshaft conical surface place.
Background technology
The frock that has dismounting oil pump test tapered sleeve now mainly is the Three-claw pull-horse frock, acts on the outer step of tapered sleeve location by three-jaw when Three-claw pull-horse uses, and directly moment of torsion is done work in addendum cone, and the malleation camshaft generation pressure that moves axially of addendum cone comes off tapered sleeve.Three-claw pull-horse is a kind of general tool of unloading, be easy to buy in dynamo-electric market, the weak point of this frock is to use inconvenient, install and apply in the power process and skid easily, and frock itself rebounds easily, shake certainly, security is relatively poor, in addition, because Three-claw pull-horse mostly is tool steel as its material of finished product instrument, heat treatment hardness is bigger, therefore very big to the cylindrical fine positioning surface damage of tapered sleeve itself, had a strong impact on service life.Three-claw pull-horse is because its design characteristics addendum cone length must surpass three-jaw length, addendum cone length is big especially like this, mass ratio is bigger, usually greater than 2kg, for loss of weight, the critical component addendum cone diameter of Three-claw pull-horse itself reduces, and its ability of transmitting moment of torsion weakens greatly, also just required great effort the consequence that long-term use causes exposed addendum cone shaft radial deformation to cause frock to be scrapped easily during use relatively.
Summary of the invention
Task of the present utility model is the weak point at existing Three-claw pull-horse, and a kind of frock that can dismantle the oil pump test tapered sleeve laborsaving, quick, safely is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of frock for dismounting oil pump test tapered sleeve, comprise, tapered sleeve 1 and addendum cone 3, it is characterized in that tapered sleeve 1 is one by being shaped on the internal thread stepped hole with Connection Block 2 coaxial being spirally connected, addendum cone 3 falls in the stepped hole of tapered sleeve 1 by Connection Block 2 screwed hole of centre, do work in addendum cone 3 by moment of torsion, addendum cone 3 screw thread pair spirals produce moves axially pressure, and tapered sleeve is come off.
The utility model has following beneficial effect than prior art.
The utility model utilizes the latching characteristics of screw thread pair to replace the three-jaw of three-point fix pattern.The diameter of thread of big addendum cone, need not three-jaw just can do work in addendum cone by moment of torsion, move axially pressure and can realize fast, dismantle safely coming off of oil pump test tapered sleeve through what addendum cone screw thread pair spiral produced, and the length of addendum cone, can shorten more than 2/3 than Three-claw pull-horse, the weight ratio Three-claw pull-horse reduces more than 2/3.Increase the effective transfer function power of the diameter of thread of addendum cone, operate more laborsaving, operating efficiency improves more than 50%, in the use, because the mutual constraint of screw thread pair, the distortion of addendum cone and tapered sleeve is minimum, and the frock proportion of goods damageds are extremely low, improve service life more than 1 times, can not be similar to the accident of Three-claw pull-horse bounce-back and tapered sleeve fly bomb.
Description of drawings
Fig. 1 is the structure schematic three dimensional views of the utility model dismounting oil pump test tapered sleeve frock.
Fig. 2 is the structure central cross-sectional view of the utility model dismounting oil pump test tapered sleeve frock.
Among the figure: 1 tapered sleeve, 2 Connection Blocks, 3 addendum cones, 4 spanners, 5 straight pins, 6 blind holes, 7 conical through-holes.
The specific embodiment
Consult Fig. 1, Fig. 2.In the following embodiments, constitute this dismounting oil pump test tapered sleeve frock, comprise tapered sleeve 1, Connection Block, addendum cone 3 and spanner 4.Tapered sleeve 1 is by being shaped on the internal thread stepped hole, Connection Block 2 coaxial Luo connect be one.Tapered sleeve 1 inner headed face adopts female thread structure, and Connection Block 2 cylindrical steps adopt external thread structure and aforementioned tapered sleeve 1 female thread structure to form screw thread pair.Connection Block 2 through holes adopt female thread structure, and addendum cone 3 external screw threads and aforementioned Connection Block 2 internal threads are formed screw thread pair.Addendum cone 3 falls in the stepped hole of tapered sleeve 1 by Connection Block 2 screwed hole of centre.Addendum cone 3 upper ends are shaped on square or regular hexagon swivel head.Be shaped on 4 liang of symmetries of corresponding spanner in the upper surface of Connection Block 2 and pull two blind holes 6 of mouthful straight pin 5.Mode or alternate manner that swivel head also can adopt radial hole to insert the pin rod are realized rotation.Be used for spanner 4 A/Fs and addendum cone 3 squares or the regular hexagon swivel head width coupling of dismounting Connection Block 2, keep matched in clearance.
During dismounting oil pump test tapered sleeve, manual or adopt spanner 4 rotation addendum cones 3 upper ends to be processed into square or regular hexagon swivel head, addendum cone 3 is screwed in the Connection Block 2, the active force moment of torsion that screws in addendum cone 3 transmits, addendum cone 3 axially-movables in tapered sleeve 1, when the top conical through-hole 7 by tapered sleeve 1 stepped hole lower end of addendum cone 3, are contacted after the fuel injection camshaft, addendum cone 3 screw thread pair spirals produce moves axially pressure, the coming off of dismounting oil pump test tapered sleeve.Tapered sleeve 1 separates with Connection Block, two the straight pin 5 that can connect firmly by spanner 4 head lower surfaces, and over against two blind holes 6 of inserting Connection Block 2 upper surface correspondences, turn spanner 4 namely takes out Connection Block 2, finishes whole unloading process.
