Abstract
The utility model relates to the technical field of press machines, and in particular relates to a separated connecting rod mechanism which has high machining precision and low machining difficulty and is convenient to maintain. The separated connecting rod structure comprises a connecting rod body; a screw rod mounting hole is formed in the connecting rod body; an inner barrel is inserted into the screw rod mounting hole in a matched manner; and the end part, connected with the connecting rod body, of the inner barrel is fixed by a piston and a gland. According to the separated connecting structure disclosed by the utility model, as the inner barrel is arranged in the mounting hole and all internal threads connected with screw rods are arranged on the inner barrel, the machining difficulty of the connecting rod body is reduced and the machining precision of the internal threads is accurately ensured as well, so that the die-filling height of the press machine is accurately ensured, and simultaneously, the separated structural design is also convenient for arrangement of a casting technique of connecting rods.
Description
Technical field
The utility model relates to the press technologies field, particularly a kind of machining accuracy height, and difficulty of processing is low, the split bar linkage structure of the press machine of being convenient to safeguard.
Background technique
The market demand of large-tonnage high-speed fine press is increasing at present, and also more and more higher to the requirement of press machine height of packing compact and height of packing compact regulated quantity, this has proposed very high requirement to press connecting rod.The adjusting of press machine height of packing compact mainly is that worm and gear drives ball screw, by being threaded to realize between ball screw and the connecting rod, because the height of packing compact regulated quantity of large high-speed fine press is big and required precision is high, be threaded length and precision to ball screw and connecting rod have proposed very high requirement, especially the internal thread of connecting rod, the man-hour difficulty is bigger adding.For integral type connecting rod in the past, the screw thread difficulty of processing is bigger, and precision can't guarantee, and is difficult for sand removal when connecting the blank casting.
The model utility content
The utility model provides a kind of mounting or dismounting easy to maintenance at the problem that prior art exists, and difficulty of processing is low, is convenient to regulate the split bar linkage structure of press arrangement height.
The purpose of this utility model is to realize like this, a kind of split bar linkage structure comprises connecting rod shank, is provided with the screw rod mounting hole in the connecting rod shank, cooperate in the described screw rod mounting hole to be embedded with interior swivel nut, the end that described interior swivel nut is connected with connecting rod shank is fixed by piston and gland.
Adopt split bar linkage structure of the present utility model, by interior swivel nut is set, in all being arranged on, the internal thread that will be connected with screw rod on the swivel nut, reduced the difficulty of processing of connecting rod shank in mounting hole, can also accurately guarantee the machining accuracy of internal thread, thereby accurately guarantee the press machine height of packing compact; Simultaneously, the split-type design structure also is convenient to internal thread sand removal processing.
Fixedly connected for ease of interior swivel nut, the upper end of described screw rod mounting hole is the unthreaded hole that cooperates with screw clearance, the underpart is provided with the step hole for swivel nut in installing, the swivel nut cooperation is inlaid in the step hole in described, the outer end of interior swivel nut is provided with for the counter sink that piston is installed, the swivel nut periphery is connected with the cooperation mounting hole drive fit of connecting rod shank in described, piston cooperates to be installed in the counter sink, the outer end is fixed by gland, and described gland end is provided with some be used to the bolt that is fixed gland and piston.In this structure, the screw rod mounting hole is divided into the section of being threaded on the swivel nut in the unthreaded hole section on top and the bottom, has made things convenient for the adjusting of screw rod setting height(from bottom), thereby makes press connecting rod adapt to different height of packing compact requirements, has enlarged the using scope of press machine.
Be further to improve the quality of fit of connecting rod and screw rod, described piston and interior swivel nut are connected is circumferentially with high-pressure seal ring.During installation, be equipped with high pressure oil at the fitting surface place that is threaded and reduce matching gap between the screw thread, improve the precision of press machine when punching press.
Description of drawings
Fig. 1 is of the present utility model minute attachment structure schematic representation.
Wherein, 1 connecting rod shank; Swivel nut in 2; 3 pistons; 4 seal rings; 5 glands; 6 bolts; 7 screw rods.
Embodiment
Be illustrated in figure 1 as split bar linkage structure of the present utility model, comprise connecting rod shank 1, be provided with the screw rod mounting hole in the connecting rod shank 1, cooperate in the screw rod mounting hole to be embedded with interior swivel nut 2, the end that interior swivel nut 2 is connected with connecting rod shank 1 is fixing by piston 3 and gland 5.Adopt split bar linkage structure of the present utility model, by swivel nut 2 in mounting hole, arranging, in all being arranged on, the internal thread that will be connected with screw rod 7 on the swivel nut 2, reduced the difficulty of processing of connecting rod shank 1, can also accurately guarantee the machining accuracy of internal thread, thereby accurately guarantee the press machine height of packing compact; Simultaneously, the split-type design structure also is convenient to internal thread sand removal processing.
Fixedly connected for ease of interior swivel nut 2, the upper end of screw rod mounting hole is the unthreaded hole with screw rod 7 Spielpassung, the underpart is provided with the step hole for swivel nut 2 in installing, interior swivel nut 2 cooperations are inlaid in the step hole, the outer end of interior swivel nut 2 is provided with for the counter sink that piston 3 is installed, interior swivel nut 2 peripheries are connected with the cooperation mounting hole drive fit of connecting rod shank 1, and piston 3 cooperates the interior outer end of installation counter sink fixing by gland 5, and gland 5 ends are provided with some be used to the bolt 6 that is fixed gland 5 and piston 3.In this structure, the screw rod mounting hole is divided into the section of being threaded on the swivel nut 2 in the unthreaded hole section on top and the bottom, has made things convenient for the adjusting of screw rod setting height(from bottom), thereby makes press connecting rod adapt to different height of packing compact requirements, has enlarged the using scope of press machine.
Be further to improve the quality of fit of connecting rod and screw rod, piston 3 and interior swivel nut 2 are connected is circumferentially with high-pressure seal ring 4.During installation, be equipped with high pressure oil at the fitting surface place that is threaded and reduce matching gap between the screw thread, improve the precision of press machine when punching press.
The utility model is not limited to above-described embodiment; every on the basis of the disclosed technological scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characteristicss wherein, these replacements and distortion are all in the scope of the utility model protection.
