Description
Technical field
The utility model relates to screw thread verticality and detects, and is specifically related to a kind of screw thread verticality detection device of engine cylinder cap bolt.
Background technology
In the actual production process of engine cylinder cap bolt, general enterprises is due to the limitation of production equipment, the screw thread verticality of engine cylinder cap bolt is made to be difficult to control, cause the verticality out-of-size scope of bolt bearing end face double thread center line, use the cylinder bolt that these screw thread verticalities exceed standard, allow between engine cylinder cover and cylinder body and obtain good sealing effectiveness, must increase pretightning force, this will cause bolt to connect overload.
Utility model content
The purpose of this utility model is the screw thread verticality detection device providing a kind of engine cylinder cap bolt, and the utility model structure is simple, can detect the screw thread verticality of engine cylinder cap bolt fast.
The technical scheme that the utility model relates to:
The screw thread verticality detection device of engine cylinder cap bolt, is made up of clock gauge, clock gauge retainer plate, gland screw, spring capping, wedge shape thimble, wedge shape pushing block, spring, retainer plate, standard thread seat, cylinder bolt to be measured.
Six sides of described retainer plate all have through hole, and the other end in hole leads to top.
Wedge shape pushing block is had in the sidewise hole of described retainer plate, spring is equipped with in the outside of wedge shape pushing block, the outside of spring is pushed down by spring capping, when the screw thread verticality detection device of engine cylinder cap bolt does not work, under the elastic force effect of spring, wedge shape pushing block is forced into innermost position, and described spring capping is glanded screw and is fixed on retainer plate.
Have circular hole in described spring capping, the bar portion of clock gauge is arranged in circular hole, fixes with clock gauge retainer plate, and the gauge outfit of clock gauge contacts with wedge shape pushing block.
Described wedge shape thimble is vertically mounted in the hole of retainer plate, and when the screw thread verticality detection device of engine cylinder cap bolt does not work, the upper surface of retainer plate is exposed at the top of wedge shape thimble.
There is the inclined-plane of 45 ° the lower end of described wedge shape thimble, there is the inclined-plane of 45 ° the inner end of wedge shape pushing block, the lower end of wedge shape thimble and the inner end of wedge shape pushing block facing each other, when moving down under the External Force Acting that wedge shape thimble is subject to vertically downward, promote the outwards movement of wedge shape pushing block, after the power on wedge shape thimble that is applied to is cancelled, under the elastic force effect of spring, wedge shape pushing block can move inwards, promotes wedge shape thimble and moves up.
The upper supporting end face of described standard thread seat reaches the standard-required of testing tool relative to the verticality of thread center's line.
The utility model has the advantages that: structure is simple, can detect the screw thread verticality of engine cylinder cap bolt fast.
Accompanying drawing explanation
Fig. 1 is complete section structural representation of the present utility model.
Fig. 2 is plan structure schematic diagram of the present utility model.
Fig. 3 is the complete section structural representation of the utility model when screw thread verticality detects.
Wherein: 1. clock gauge, 2. clock gauge retainer plate, 3. gland screw, 4. spring capping, 5. wedge shape thimble, 6. wedge shape pushing block, 7. spring, 8. retainer plate, 9. standard thread seat, 10. cylinder bolt to be measured.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, the screw thread verticality of engine cylinder cap bolt detects dress and is made up of clock gauge 1, clock gauge retainer plate 2, gland screw 3, spring capping 4, wedge shape thimble 5, wedge shape pushing block 6, spring 7, retainer plate 8, standard thread seat 9, cylinder bolt to be measured 10 the utility model.
Six sides of described retainer plate 8 all have through hole, the other end in hole leads to top, there is wedge shape pushing block 6 the inside of sidewise hole, spring 7 is equipped with in the outside of wedge shape pushing block 6, the outside of spring 7 is pushed down by spring capping 4, and spring capping 4 is glanded screw 3 and is fixed on retainer plate 8, when the screw thread verticality detection device of engine cylinder cap bolt does not work, under the elastic force effect of spring 7, wedge shape pushing block 6 is forced into innermost position; Have circular hole in described spring capping 4, the bar portion of clock gauge 1 is arranged in circular hole, and fix with clock gauge retainer plate 2, the gauge outfit of clock gauge 1 contacts with wedge shape pushing block 6.
Described wedge shape thimble 5 is vertically mounted in the hole of retainer plate 8, and when the screw thread verticality detection device of engine cylinder cap bolt does not work, the upper surface of retainer plate 8 is exposed at the top of wedge shape thimble 5; There is the inclined-plane of 45 ° the lower end of described wedge shape thimble 5, there is the inclined-plane of 45 ° the inner end of wedge shape pushing block 6, the lower end of wedge shape thimble 5 and the inner end of wedge shape pushing block 6 facing each other, when moving down under the External Force Acting that wedge shape thimble 5 is subject to vertically downward, promote the outwards movement of wedge shape pushing block 6, after cancelling the power be applied on wedge shape thimble 5, under the elastic force effect of spring 7, wedge shape pushing block 6 can move inwards, promotes wedge shape thimble 5 and moves up.
In the utility model, the screw thread verticality detection device of engine cylinder cap bolt is put into standard thread seat 9 upper surface, cylinder bolt 10 to be measured rotates a few circle through after the endoporus of retainer plate 8, clock gauge 1 is returned to zero, six numerical value showing display are allowed to be zero, then cylinder bolt 10 to be measured is tightened, after allowing cylinder bolt 10 to be measured reach the pretightning force of its regulation, read the reading of six tables, in six tables, three tables are wherein arranged symmetrically with other three tables, three, the reading of clock gauge symmetrical is separately subtracted each other, the maximum numerical value of difference is exactly the verticality of thread center and stressed workplace.
