Description
Technical field
The utility model relates to a kind of welding tooling, is specifically related to a kind of tailor-welding tool of excavator connecting rod.
Background technology
In excavator connecting rod production process, because the parts of its connecting rod of composition are many, so manufacturing process is very loaded down with trivial details, making in the prior art excavator connecting rod is all generally to rule and locate or rely on the method that allowance is amplified to complete by operating personnel, be difficult to like this batch production, cause the quality of the connecting rod of producing unstable, element precision is also very low.
Summary of the invention
Utility model object: the purpose of this utility model is for the deficiencies in the prior art, and the tailor-welding tool of the excavator connecting rod welding after a kind of parts of composition excavator connecting rod can being fixed according to position relationship entirety is provided.
Technical scheme: the utility model provides a kind of tailor-welding tool of excavator connecting rod, comprise base, on described base, be fixed with the first locating dowel and the second locating dowel, the upper end of described the first locating dowel and the second locating dowel is provided with fixed head, described fixed head is fixed in the first locating dowel and the second locating dowel by fixture, and described the first locating dowel middle part cover has a packing ring.
Further, described fixed head comprises upper guide plate and gland, wherein said upper guide plate is provided with the hole adapting with the first locating dowel and the second locating dowel, on described two holes, cover respectively and be fixed with gland, on described gland, there is the hole adapting with fixture, upper guide plate can be fixed in two locating dowels by gland like this, has effectively prevented that upper guide plate from sliding on lead, has avoided because the fixing not fastening problem that is welded with error causing of the part of excavator connecting rod.
Further, institute's fixture comprises the stud of two groups of M20 and the hex nut of M20, one end of the stud of wherein said each M20 is separately fixed at the center at the first locating dowel and the second locating dowel top, can guarantee that so whole frock is fixed together each part of excavator connecting rod closely in the time of welding, can not produce displacement and cause the position of welding inaccurate.Adopt the good fixing effect of the screw bolt and nut of this specification, be more suitable for whole frock.
Further, between described the first locating dowel and base and upper guide plate, be lined with respectively pad, like this can be according to the height of the width adjustment frock of part, also effectively increase fixing effect simultaneously, make between the first locating dowel and base and upper guide plate be connected more fastening.
Further, described base is provided with at least one base pad, can be applicable to like this excavator connecting rod of different model, and the height of base pad also can be adjusted according to demand.
Further, described base plate is lined with two, can guarantee that like this panel of excavator connecting rod can be arranged in frock stably, thus convenient welding.
Operation principle: when the utility model uses, first the axle bed of excavator connecting rod is arranged in the first locating dowel, again the bearing of excavator connecting rod is enclosed within the second locating dowel, finally the panel of excavator connecting rod is placed between axle bed and bearing, be fixed by upper guide plate, gland and fixture, the relative position when axle bed of excavator connecting rod, bearing and panel are fixed to finished product welds.
Beneficial effect: compared with prior art, the utility model is easy and simple to handle in the time that soldering part clamps, and positioning precision is high, has greatly promoted operating efficiency and machining accuracy, has guaranteed the quality of product, has reduced production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is working state figure of the present utility model.
The specific embodiment
Below technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
embodiment 1:as depicted in figs. 1 and 2, a kind of tailor-welding tool of excavator connecting rod, comprise base 1, the first locating dowel 2 and the second locating dowel 3 are installed on base 1, the upper end of the first locating dowel 2 and the second locating dowel 3 is provided with fixed head 4, fixed head 4 comprises upper guide plate 41 and gland 42, and wherein said upper guide plate 41 is provided with the slightly large hole of diameter than the first locating dowel 2 and the second locating dowel 3, can make like this upper guide plate 41 be enclosed within the first locating dowel 2 and the second locating dowel 3, on two holes, cover respectively and be fixed with gland 42, on gland 42, there is the hole adapting with fixture 5, wherein, fixture 5 comprises the stud of two groups of M20 and the hex nut of M20, wherein one end of the stud of each M20 is separately fixed at the center at the first locating dowel 2 and the second locating dowel 3 tops, the diameter of the stud of the hole on gland 42 and fixture 5 adapts, gland 42 can be through the other end of stud, the nut of fixture 5 can screw in from the other end of stud like this, fixed head 4 is fixed on to the upper end of the first locating dowel 2 and the second locating dowel 3.Between the first locating dowel 2 and base 1 and upper guide plate 41, being lined with pad 7, the first locating dowel 2 middle part covers has a packing ring 6, is also provided with two base pad 8 on base 1 between two locating dowels.
Before welding, fixture 5 is unclamped, take off fixed head 4.Then take out pad 7 and packing ring 6.So far, the first locating dowel and the second locating dowel that are arranged on base in frock, have only been retained.
The lower axle bed of excavator connecting rod is first inserted in the first locating dowel 2, then is inserted in the upper axle bed of packing ring 6 and excavator connecting rod.Gap between such two axle beds is controlled by packing ring, does not need so too much technology and installation time, also can obtain accurate locating effect.Then the bearing of excavator connecting rod is inserted in to the second locating dowel 3, excavator connecting rod panel is vertically placed in two base pad 8, the two ends of excavator connecting rod panel contact with bearing with the axle bed of excavator connecting rod respectively.Finally fixed head 4 installed to the upper end of the first locating dowel 2 and the second locating dowel 3 and be pressed in panel upper end, then the nut of fixture 5 is screwed in and screwed fixing fixed head 4, the position of the position of axle bed, bearing and panel that makes excavator connecting rod in excavator connecting rod finished product, complete after each parts clamping of excavator connecting rod, each parts are welded.
