Description

Engineering machinery connecting rod special tooling
Technical field
It the utility model is related to a kind of machinery processing apparatus, more particularly to a kind of engineering machinery connecting rod special tooling.
Background technology
, it is necessary to ensure the axiality of positioning linkage rod pipe when the small-sized connecting rod of engineering machinery installs circular positioning linkage rod pipe additional, if During installation there is deviation in two axle center, may result in product deviation, influences the product quality after processing, causes product rejection, mesh Preceding generally use casting grinding tool mode completes preparatory processing, then carries out the secondary finishing of turning, ensures related axiality and chi Very little alignment tolerance, processing charges are of a relatively high.
Utility model content
The purpose of this utility model is to overcome existing defect, a kind of engineering machinery connecting rod special tooling is proposed, to bone rod Welding is grouped in the additional circular positioning linkage rod pipe of type connecting rod, by setting locating piece, alignment pin, makes bone after welding manufacture Rod type connecting rod is positioned in the margin of tolerance, ensures the positioning precision of frock size and the axiality of link tube, the utility model weldering Connect and be unlikely to deform, reduce processing cost.
The utility model is realized using following technical scheme:
A kind of engineering machinery connecting rod special tooling, including base, cushion block, locating piece and alignment pin, cushion block are separately positioned on Base both ends, cushion block both sides are provided with locating piece, and alignment pin level runs through locating piece, is set between alignment pin and locating piece tight Firmware.
Described, cushion block is symmetricly set on the both ends of base, and locating piece is symmetricly set on the both sides of cushion block, base both ends position The center line for putting corresponding alignment pin overlaps.
Described, positioning hole is set on the outside of cushion block.
Described, base selects I-steel or channel-section steel, is shaped as rectangle.
Alignment pin is against on locating piece through link tube, is fastened by fastener, the corresponding alignment pin of base end positions Center line overlap, making the axis of link tube of correspondence position, the both ends of bone rod type connecting rod ride over base two on the same line On the cushion block at end, the middle section of bone rod type connecting rod and the axis of link tube in same level, positioning hole on the outside of cushion block with Through hole on bone rod type connecting rod is corresponding, for positioning the position of bone rod type connecting rod and link tube, ensures the positioning accurate of frock size The axiality of degree and link tube.
The beneficial effects of the utility model are:
(1) engineering machinery connecting rod special tooling described in the utility model, be provided with the cushion block being arranged symmetrically, locating piece, Alignment pin, avoid ensureing using long connecting rod design the axiality of postwelding through hole, reduce processing cost.
(2) engineering machinery connecting rod special tooling described in the utility model, is provided with positioning hole, and positioning hole connects with bone rod type Through hole on bar is corresponding, and the middle section of bone rod type connecting rod and the axis of link tube ensure frock size in same level Positioning precision, it is unlikely to deform after welding.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As Figure 1-5, engineering machinery connecting rod special tooling described in the utility model, including base 1, cushion block 2, positioning Block 3 and alignment pin 4, cushion block 2 are separately positioned on the both ends of base 1, and the both sides of cushion block 2 are provided with locating piece 3, and the level of alignment pin 4 is passed through Locating piece 3 is worn, fastener is set between alignment pin 4 and locating piece 3;Cushion block 2 is symmetricly set on the both ends of base 1, and locating piece 3 is right Claim the both sides for being arranged on cushion block 2, the center line of the corresponding alignment pin 4 of the end positions of base 1 overlaps;The outside of cushion block 2 is set Put positioning hole 5;Base 1 selects channel-section steel, is shaped as rectangle.
Alignment pin 4 is against on locating piece 3 through link tube 6, is fastened by fastener, and the end positions of base 1 are corresponding to determine The center line of position pin 4 overlaps, and making the axis of link tube 6 of correspondence position, the both ends of bone rod type connecting rod 7 ride on the same line On the cushion block 2 at the both ends of base 1, the middle section of bone rod type connecting rod 7 and the axis of link tube 6 are in same level, the outside of cushion block 2 Positioning hole 5 it is corresponding with the through hole 8 on bone rod type connecting rod 7, for positioning the position of bone rod type connecting rod 7 and link tube 6, ensure work Fill the positioning precision of size and the axiality of link tube 6.
It is of the present utility model as described below using process:Alignment pin is against on locating piece through link tube, by fastener Fastening, bone rod type connecting rod is ridden on cushion block, and the through hole on bone rod type connecting rod overlaps with positioning hole, inserts suitable locating rod, Welding is grouped in circular positioning linkage rod pipe additional to bone rod type connecting rod.
Certainly, the above is only preferred embodiment of the present utility model, it is impossible to is considered as being used to limit to this practicality newly The scope of embodiments of type.The utility model is also not limited to the example above, and those skilled in the art are in this reality With equivalent change and improvement made in new essential scope etc., patent covering scope of the present utility model all should be belonged to It is interior.
