It can be carried out adjustment, for crankshaft, a large amount of crankshaft is all the weight of equivalent ring applied by special, special crankshaft
There are particularity, be generally difficult to be applied to other crankshafts, special crankshaft caused once to detect completion, it is matching use work as
It is just useless to measure ring, can only scrap, cause serious waste.
Summary of the invention
For disadvantages described above, the purpose of the utility model is to provide a kind of combined type equivalent rings, it is intended to solve the prior art
The technical issues of middle equivalent ring weight cannot be adjusted.
In order to solve the above technical problems, the technical solution of the utility model is:
A kind of combined type equivalent ring, including ring body and several clump weights, ring body outer wall middle are equipped with annular groove, ring body
Side wall is equipped with several first pin holes, and clump weight is equipped with main part, and the bottom of main part is equipped with interconnecting piece, and interconnecting piece can accommodate
In in annular groove, interconnecting piece is equipped with for the second pin hole corresponding with the first pin hole, and main body section is in the bottom of interconnecting piece two sides
The outer wall of portion and ring body matches.
Wherein, several first pin holes are even number, and are uniformly arranged around the center of ring body.
Wherein, ring body includes the semicircular ring of two docking, is bolted at the docking of two halves annulus.
Wherein, it is two at the docking of two halves annulus, is connected to the center pair that the bolt at two docking surrounds ring body
Claim.
Wherein, one end of semicircular ring is equipped with protrusion, and the other end is equipped with the card slot to match with protrusion.
After above-mentioned technical proposal, the beneficial effects of the utility model are:
Since the utility model combined type equivalent ring includes ring body and several clump weights, ring body outer wall middle is equipped with ring
The interconnecting piece of shape slot, clump weight is contained in annular groove, and is fixed with ring body by fixed pin, and main body section is in interconnecting piece two sides
Bottom and the outer wall of ring body match, so that quick installation of the clump weight in ring body is realized, by installing not in ring body
Clump weight with weight comes, and realizes the tune to equivalent ring overall weight by the combination of the clump weight of ring body and different weight
Section, and clump weight is dismounted easily in ring body, and the two stability after assembly is high.
It since several first pin holes are even number, and uniformly arranges around the center of ring body, allows clump weight with right
One group claimed is installed in ring body, so that the center of gravity of the equivalent ring after combination is always positioned at ring body center, guarantees the matter of equivalent ring
Amount.
Since ring body includes the semicircular ring of two docking, it is bolted at the docking of two halves annulus, so that ring body can
To be applied to because being integrally formed and on the crankshaft that cannot be pressed.
In conclusion the utility model solves the technical issues of equivalent ring weight cannot be adjusted in the prior art, this
Utility model combined type equivalent ring can carry out free adjustment to the weight of equivalent ring, to meet to different types of crankshaft
Use demand reduces the production cost of equivalent ring, while also there is the utility model quality to stablize, and can be used in integrated molding
Crankshaft product the advantages of.
Detailed description of the invention
Fig. 1 is that a kind of one structure of combined type equivalent ring embodiment of the utility model splits schematic diagram；

In figure, 1- ring body, 10- annular groove, the first pin hole of 11-, 12- semicircular ring, 120- bolt, 121- protrusion, 122- card
Slot, 2- clump weight, 20- main part, 21- interconnecting piece, the second pin hole of 210-, 3- fixed pin.
Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
The orientation when orientation being related in this specification is worked normally with a kind of combined type equivalent ring of the utility model
Subject to, orientation when its storage and transport is not limited, is only represented opposite positional relationship, is not represented absolute positional relationship.
Embodiment one:
As shown in Figure 1, a kind of combined type equivalent ring, including ring body 1 and several clump weights 2,1 outer wall middle of ring body is set
There is annular groove 10,1 side wall of ring body is equipped with several first pin holes 11, and the first pin hole 11 is consistent with the axis direction of ring body 1, the
One pin hole 11 is connected to the two sides of ring body 1, and runs through annular groove 10；
As shown in Figure 1, clump weight 2 includes being integrally machined molding main part 20 and 21 two parts of interconnecting piece, interconnecting piece 21
Bottom end face be circular arc type, can match with the outer wall of ring body 1, interconnecting piece 21 is located at the middle of 21 bottom of interconnecting piece,
The second pin hole 210 is machined on interconnecting piece 21, the second pin hole 210 is through-hole.
As shown in Figure 1, clump weight 2 is in ring body 1 when installing, interconnecting piece 21 can completely into in annular groove 10, second
Pin hole 210 is aligned with the first pin hole 11,20 bottom of main part two at circular arc type end side can press up against in ring body 1 be located at ring
On the outer wall of 10 two sides of shape slot, fixed pin 3 is inserted into the first pin hole 11 and the second pin hole 210, to realize clump weight 2
With being fixedly connected for ring body 1.
As shown in Figure 1, the total weight of equivalent ring is the sum of the weight of 3 three of ring body 1, clump weight 2 and fixed pin, right
When the equivalent ring of different weight is arranged in pairs or groups, the weight of ring body 1 be it is fixed, by select different weight clump weight 2, with ring
Body 1 is combined, to meet the use needs to equivalent ring.
As shown in Figure 1, the first pin hole 11 is circumferentially arranged in ring body 1, and the sum of the first pin hole 11 is even number, this
Sample guarantee is divided into one group for all first pin holes 11 in same ring body 1 two-by-two, two the first pin holes 11 in a group with
The central symmetry of ring body 1 is arranged, and when deploying weight, the weight of equivalent ring is equal to ring body 1, one and assembles pouring weight 2 such equivalent ring
And the sum of the weight of one group of 3 three of fixed pin, one, which assembles pouring weight 2, is symmetrically mounted in ring body 1, ensure that equivalent ring entirety
Center is consistent with 1 center of ring body.
Embodiment two: the present embodiment and embodiment one the difference is that, as shown in Fig. 2, ring body 1 is combined type, by
