Abstract
The invention discloses a maintenance device for a bite block of an offset press. The maintenance device comprises an operating rod, a connecting rod and a chuck, wherein one end of the connecting rod is vertically connected with the middle part of the operating rod; the other end of the connecting rod is provided with the chuck; pits are respectively and evenly formed in positions, near the edge, on the upper end face of the chuck; a permanent magnet material fills in each pit; a protrusion is arranged along the axial direction of the middle part of the working end face of the chuck; two semicircular grooves are formed along the axial direction of the outer wall of the working end face; an opening is formed in a position, at the outer side wall of the working end face, on each semicircular groove; the semicircular grooves are symmetric along the center of the chuck; another lower end face of the chuck is an assembly end face; a hinge pin used for assembly is arranged along the axial direction of the assembly end face. Only the protrusion on the working end face of the chuck needs to be aligned with the through hole of the bite block, the bite block can be removed; the removed bite block is absorbed on the working end face of the chuck, and cannot drop; the maintenance time of the offset press is effectively shortened by the maintenance device, and the maintenance efficiency of the offset press can be improved by 5-6 times.
Description
Technical field
The present invention relates to offset press tooth row's spring and impression tooth row bite-block installing/dismounting device.
Background technology
At present, offset printing is the major way of printing, and because print speed printing speed is fast, the multiple advantages such as printing quality is relatively stable, and the whole print cycle is short, books and periodicals, newspaper and quite a few commercial printing are all in employing offset printing.But offset press needs monthly to maintain once, offset lithographic machine dens in dente row bite-block is the pith of printing paper product, the printing quality quality of product has 50% to be arrange coordinating between bite-block by tooth to decide, each lithographic press has 36 tooth rows, a tooth row has 150 bite-blocks, the dismounting of current bite-block and install and use normal screws cutter, cost is needed to remove and install for 10 hours each replacing when maintenance tooth arranges bite-block, when pulling down bite-block because being subject to the effect of bite-block spring force, accidentally bite-block will fall into equipment, need to take much time searching, bite-block belongs to special-shaped parts and removes and installs very difficult.
Summary of the invention
For the deficiencies in the prior art, the present invention aims to provide a kind of offset press bite-block apparatus for examination and repair, is convenient to the bite-block dismounting of offset press or installs.
For solving the problems of the technologies described above, the technical solution used in the present invention, a kind of offset press bite-block apparatus for examination and repair, comprise action bars, coupling bar, chuck, coupling bar one end connects with vertical in the middle part of action bars, the other end of coupling bar installs chuck, the described chuck upper surface place of keeping to the side evenly is provided with pit, permanent-magnet material is equipped with in pit, projection is provided with vertically at the middle part of operative end surface, two semicircle grooves are provided with vertically at operative end surface outer wall, semicircle groove forms opening at operative end surface lateral wall, described semicircle groove is symmetrical along the chuck center of circle, another lower surface of described chuck is assembled end, the bearing pin for assembling is provided with vertically in assembled end.
Action bars two ends are provided with end cap.
This end cap can be made up of the hardness copper material less relative to steel part or Other Engineering material.
This end cap is used for auxiliary assembling bite-block and other parts.
Adopt technique scheme, when carrying out bite-block dismounting, only chuck operative end surface projection need be aimed at the through hole of bite-block, two semicircle grooves of chuck operative end surface aim at the projection on bite-block body, then 90 degree, counterclockwise turning operation bar, just bite-block can be pulled down, be equipped with permanent-magnet material in pit due to chuck operative end surface, so the bite-block pulled down is adsorbed on chuck operative end surface, can not drop, when in like manner assembling bite-block, first by bite-block
Be placed on chuck operative end surface, then will send into installation position, 90 degree, clockwise turning operation bar, just can install bite-block, and this device effectively shortens maintenance, the repair time of offset press, can improve the mainteinance repair efficiency 5-6 times of offset press.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of chuck;
In accompanying drawing: protruding 32 pit 33 semicircle grooves of 1 action bars 2 coupling bar 3 chuck 31
34 bearing pin 4 end caps.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As Fig. 1, shown in Fig. 2, coupling bar 2 one end connects with vertical in the middle part of action bars 1, namely in the middle part of action bars 1, a screwed hole is processed, in coupling bar 2 one end machining screw, then action bars 1 is connected with coupling bar 2 is vertical, the other end of coupling bar 2 installs chuck 3, the described chuck 3 upper surface place of keeping to the side evenly is provided with four pits 32, chuck 3 upper surface is operative end surface, pit 32 is cylindrical, permanent-magnet material is equipped with in pit 32, because chuck 3 is processed by steel, such chuck 3 also has magnetic, protruding 31 are provided with vertically at the middle part of operative end surface, projection 31 is also cylindrical, protruding 31 play the role of positioning when dismantling bite-block, two semicircle grooves 33 are provided with vertically at operative end surface outer wall, semicircle groove 33 forms opening at operative end surface lateral wall, this opening is convenient to the projection blocked when dismantling bite-block or exit on bite-block body, described semicircle groove 33 is symmetrical along chuck 3 center of circle, can not be overlapping with pit 32 during certain processing semicircle groove 33, semicircle groove 33 is positioned at two pit 32 middle parts, another lower surface of described chuck 3 is assembled end, the bearing pin 34 for assembling is provided with vertically in assembled end, on the end face of coupling bar 2 correspondence, process and assemble hole, is fixed in pilot hole by bearing pin 34, just chuck 3 can be fixed on coupling bar 2.
Action bars 1 two ends are provided with end cap 4; the copper alloy that end cap 4 adopts hardness relatively low is made; in the repair and maintenance process of offset press; end cap 4 is for beaing some precision parts; can play in installation and debugging process and mounting and adjusting is carried out to high-precision accessory, and play the effect of protection high accuracy accessory.
