Description
Technical field
The utility model relates to a kind of downswing machine, particularly relates to a kind of lever downswing machine.
Background technology
Downswing machine is main force's equipment in optics cold working industry, its pressuring method is all direct press type, due to structural reason, objective reality pressure axis positional precision is unstable, the stressed interference that the gap of pressure axis and shaft room causes the idle running of process and pressure axis and axle sleeve friction to cause, regulate inconvenient in addition.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of lever downswing machine, and it is reliable, without idle running and without interference, easy to adjust.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of lever downswing machine, it is characterized in that, it comprises pedestal, framework, crane span structure, guide rod, bearing block, support arm, press rods, rotating shaft, adjusting device, moving cylinder, determine cylinder, frame installation is on pedestal, guide rod is fixed on framework, one end of support arm passes through rotating shaft, bearing block is installed on pedestal, the other end of support arm is connected with press rods, determining cylinder is fixed on crane span structure, one side of moving cylinder location guide, adjusting device comprises the first adjustment screw, the second adjustment screw, the 3rd adjustment screw, the first adjustment screw is connected with an end of guide rod, the second adjustment screw is connected with bearing block, the 3rd adjustment screw is connected with the top of guide rod.
Positive progressive effect of the present utility model is: the thorough degree of the utility model lever downswing machine has been overturned the compression system structure of former downswing machine, changing direct press type is lever, make the forcing shaft position adjust knot more convenient, stability improves, reliable, and the structural idle running that disappeared Chu, reduced interference, make machining eyeglass in a kind of more reliable and more stable machining state, improved the machining accuracy of eyeglass, also the expansion for the range of work of eyeglass provides condition.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model lever downswing machine.
The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the utility model lever downswing machine comprises pedestal 1, framework 2, crane span structure 3, guide rod 4, bearing block 5, support arm 6, press rods 7, rotating shaft 8, adjusting device, moving cylinder 10, determine cylinder 11, framework 2 is arranged on pedestal 1, guide rod 4 is fixed on framework 2, one end of support arm 6 is by rotating shaft 8, bearing block 5 is installed on pedestal 1, the other end of support arm 6 is connected with press rods 7, determining cylinder 11 is fixed on crane span structure 3, one side of moving cylinder 10 location guides 4, adjusting device comprises the first adjustment screw 9a, the second adjustment screw 9b, the 3rd adjustment screw 9c, the first adjustment screw 9a is connected with an end of guide rod 4, the second adjustment screw 9b is connected with bearing block 5, the 3rd adjustment screw 9c is connected with the top of guide rod 4.
The operation principle of the utility model lever downswing machine is as follows: press rods is for positioning eyeglass etc., support arm is for the driving pressure bar, adjusting device, for press rods is carried out to adjusting and the locking of three-dimensional, can also be regulated the initial pressure of press rods.The thorough degree of the utility model lever downswing machine has been overturned the compression system structure of former downswing machine, changing direct press type is lever, make the forcing shaft position adjust knot more convenient, stability improves, reliable, and the structural idle running that disappeared Chu, reduced interference, make machining eyeglass in a kind of more reliable and more stable machining state, improved the machining accuracy of eyeglass, also the expansion for the range of work of eyeglass provides condition.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
