Abstract
The utility model relates to a pull rod tool for a balance arm, and belongs to the technical field of engineering equipment manufacturing. The pull rod tool comprises a bottom plate (1), wherein movable nuts (2) are arranged on the left and right sides of the top of the bottom plate (1); fixed die holders (3) are arranged on the movable nuts (2); positioning modules (4) are arranged on the fixed die holders (3); the positioning modules (4), the fixed die holders (3) and the movable nuts (2) are fixed together with the bottom plate (1) through bolts (5); a pin shaft (6) is arranged in the center of each positioning module (4); the lower end of each pin shaft (6) is connected with the corresponding movable nut (2). According to the pull rod tool for the balance arm, the parallelism and the center distance of ear plates at the two ends of a pull rod can be effectively ensured, and the quality of a product and the production efficiency are greatly improved.
Description
Technical field
The utility model relates to a kind of counter-jib pull bar frock, belongs to technical field of engineering machinery.
Background technology
Tower machine, i.e. " derrick crane ", claims again by " tower crane ", is a kind of crane gear for construction.In general tower machine comes to be divided into by functions: basis, tower body, jacking, turn round, hoist, the part such as counter-jib, crane arm, trolley, tower top, drivers' cab, luffing.Counter-jib is used for holding torque balance, and it mainly comprises arm joint and pull bar.Pull bar mainly consists of the otic placode at middle bar body and two ends, and in process of production, the depth of parallelism of its two ends otic placode and centre-to-centre spacing are difficult to be guaranteed pull bar in the past, affected final pull bar quality, and production efficiency are lower.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of counter-jib pull bar frock is provided, and the depth of parallelism and centre-to-centre spacing that it can effectively guarantee pull bar two ends otic placode, improved product quality and production efficiency greatly.
The purpose of this utility model is achieved in that a kind of counter-jib pull bar frock, it comprises base plate, the left and right sides, described base plate top is provided with traveling nut, on described traveling nut, be provided with fixedly die holder, on described fixedly die holder, be provided with locating module, described locating module, fixedly die holder and traveling nut fix by bolt and base plate, and described locating module center is provided with bearing pin, and described bearing pin lower end is connected with traveling nut.
Compared with prior art, the utlity model has following beneficial effect:
A kind of counter-jib pull bar of the utility model frock, the depth of parallelism and centre-to-centre spacing that it can effectively guarantee pull bar two ends otic placode, improved product quality and production efficiency greatly.
