Description
Technical Field
The utility model relates to a scriber technical field, especially a scriber cutter quick replacement device.
Background
The thickness of a scribing cutter of the scribing machine is very thin, and the processed workpiece is generally high in hardness, particularly the workpiece such as ceramic is easy to wear when the scribing cutter is put in the working process; if the dicing saw is not replaced in time, a large error occurs in the dicing saw, and therefore the dicing saw is often replaced with a tool. When an existing dicing saw is used for tool changing, a nut is generally directly used for screwing, although the nut is simple, the nut can rub the end face of a blade when being screwed, so that the performance of the blade is affected, and meanwhile, due to the fact that the thickness of the blade is small, appropriate pretightening force is needed, deformation and breakage caused by excessive extrusion of the blade are avoided; the current use generally requires the use of a torque wrench for the determination.
Disclosure of Invention
To the above circumstances, for solving the problem that exists among the prior art, the utility model aims at providing a scribing machine cutter quick replacement device, can effectively solve the inconvenient problem of scribing cutter change.
The technical scheme includes that the device comprises a transversely placed mounting shaft, a mounting disc is fixed on the mounting shaft, a blade is sleeved on the mounting disc, an annular extrusion disc is sleeved on the mounting shaft, and the left side face of the extrusion disc can press the blade; a plurality of grooves are uniformly distributed on the circumference of the right side surface of the extrusion disc; an annular positioning disc capable of moving left and right is sleeved on the mounting shaft, a plurality of guide rods are uniformly distributed on the circumference of the positioning disc, the left ends of the guide rods can be arranged in grooves of the extrusion disc, nuts are mounted at the right ends of the guide rods, and a pressure spring positioned between the nuts and the positioning disc is sleeved on each guide rod; the right-hand member of positioning disk is equipped with the arch, has run through between installation axle and the arch to have positioning bolt.
The utility model discloses it is convenient to dismantle, does not hinder the blade, and pretension control is convenient simultaneously, does not need the regulation of relapse, has improved efficiency.

Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model comprises a transversely placed installation shaft 1, a mounting plate 2 is fixed on the installation shaft 1, a blade 3 is sleeved on the mounting plate 2, an annular extrusion plate 4 is sleeved on the installation shaft 1, and the blade 3 can be pressed tightly by the left side surface of the extrusion plate 4; a plurality of grooves 5 are uniformly distributed on the right side surface of the extrusion disc 4; an annular positioning disk 6 capable of moving left and right is sleeved on the mounting shaft 1, a plurality of guide rods 7 are uniformly distributed on the circumference of the positioning disk 6, the left ends of the guide rods 7 can be placed in the grooves 5 of the extrusion disk 4, nuts are mounted at the right ends of the guide rods 7, and a pressure spring 8 positioned between the nuts and the positioning disk 6 is sleeved on each guide rod 7; the right end of the positioning disk 6 is provided with a bulge 9, and a positioning bolt 10 penetrates between the mounting shaft 1 and the bulge 9.
For more convenient positioning and installation of the positioning bolt 10, the cross section of the right end of the mounting shaft is square.
In order to realize the adjustment of the pressure and avoid shaking, a plurality of nuts are arranged on each guide rod 7.
In order to better realize the installation and the positioning of the blade 3, the installation disc 2 is in a step shape, the diameter of the left side is larger than that of the right side, and the blade 3 is sleeved on the right side part of the installation disc 2.
When the utility model is used, firstly, the mounting disc 2 is fixedly mounted with the mounting shaft 1; when a cutter is specifically installed, firstly, the blade 3 needs to be sleeved on the installation disc 2, and the central hole of the blade 3 is sleeved at the right end of the installation disc 2, referring to fig. 2, at this time, the right side of the blade 3 exceeds the right end face of the installation disc 2; then the extrusion disc 4 is sleeved on the mounting shaft 1; then the positioning plate 6 is sleeved on the mounting shaft 1; and the left ends of a plurality of guide rods 7 on the positioning plate 6 are arranged in corresponding grooves 5 on the extrusion plate 4.
At the moment, the guide rod 7 is sleeved with the pressure spring 8 positioned between the nut and the positioning disc 6, so that when the positioning disc 6 is extruded leftwards, the tension spring is stretched, and the extrusion force between the extrusion disc 4 and the blade 3 can be conveniently adjusted by adjusting the position of the nut.
After the bulge 9 on the positioning disk 6 is also sleeved on the mounting shaft 1, the positioning bolt 10 penetrates through the bulge 9 on the positioning disk 6 and the right end of the rotating shaft at the moment, and the nut is screwed, so that the whole cutter can be mounted.
Because the mounting disc 2 is fixed, the positioning disc 6 is fixed with the mounting shaft 1 through the positioning bolt 10, and the extrusion disc 4 rotates with the positioning disc 6 through the guide rod 7 and the groove 5, the extrusion disc 4 and the mounting disc 2 can rotate with the mounting shaft 1; and the blade 3 is clamped tightly by the extrusion disc 4 and the mounting disc 2 through the force of the pressure spring 8.
Because the dynamics of pressure spring 8 has been adjusted in advance, consequently when installing at every turn, need not use torque wrench, can make the pretightning force of blade 3 reach the standard, improved work efficiency.
When needs are dismantled, press positioning disk 6 at first to extract positioning bolt 10, positioning disk 6, extrusion dish 4 can take out this moment, thereby carry out the change of cutter, and simple quick can not produce and skid, have avoided the wearing and tearing to blade 3.
The utility model realizes the extrusion of the blade 3 by arranging the extrusion disc 4, then applies force and positions by the positioning disc 6, and is installed by the positioning bolt 10 between the positioning disc 6 and the installation shaft 1, thereby avoiding the abrasion between each part and the blade 3 when in installation and disassembly; simultaneously, the pre-tightening force for installing the blade 3 can be conveniently controlled, a torque wrench does not need to be frequently used, and the efficiency is improved.
