The specific embodiment
As is known, in ceramic tile cutter, at the lower end of tool rack 1, engraving tool is installed.Typically, engraving tool is the shape of the wheel R being made up of hard metal, and is arranged on the bottom of tool rack main body 1a, and control crank 1b is from tool rack main body 1a.
Tool rack main body 1a is connected slit 2 longitudinally to be run through, and perforation slit 2 forms the sliding seat of the guide rod (not shown) of ceramic tile cutter.Because guide rod has square-section conventionally, therefore the inside of slit 2 also has at least two and is parallel to each other and smooth lateral sliding surface 2 ' (Fig. 2).Tool rack 1 conventionally for example, by light metal alloy (aluminium) by molded and subsequently working surface is carried out to finishing and make: the shape and size of slit and relative slidingsurface 2 ' are therefore fixed.
According to the utility model, a side surface in two side surfaces 2 ' of slit has cut portion 3, and this cut portion makes it possible to approach adjacent housing chamber 4.Housing chamber 4 is as the seat portion of backing roll 5, and this backing roll 5 is for example rotatably arranged on rotating dog 6 by two bearings 5 '.Roller 5 is preferably by making than the more ductile material of guide rod, to can not damage the surface of described guide rod; For example, roller 5 for example, is made up of the plastic material (, special teflon) of self-lubricating.
Rotating dog 6 engages with the retaining hole being arranged in the terminal block of support 7 by its end then.
In addition, support 7 has two through hole 7a and 7b, and these two through hole 7a and 7b are formed in the end block of the axis that is orthogonal to rotating dog 6.In through hole 7a and 7b, will insert fastening and adjustment screw 8a and 8b, these fastening and adjustment screw 8a and 8b and the respective screw hole 9(Fig. 3 being correspondingly formed in tool rack main body) engage.These screwed holes are preferably placed at two relative bight places of support 7, and it has the top plan view shape of general rectangle; Under any circumstance, hole 7a and 7b do not aim on the same side of support 7, thereby the power that tightens is distributed in preferably rack body and is therefore distributed on roller 5, and do not produce torque, this torque trends towards causing the main body rotation of support with respect to tool rack 1a, thus cause support to produce not expecting to have lax.
Preferably, between the main body of tool rack 1a and support 7, be furnished with elastic device (not shown), this elastic device is arranged to, and the constraint that opposing is caused by fastening and adjustment screw 8a and 8b, promotes support away from tool rack.Elastic device is for example the form of spring washer, this elastic washer by key on the bar of fastening and adjustment screw 8a and 8b.
Once roller 5 fits together with support 7, and this assembly has been installed on the housing chamber 4 of tool rack main body (Fig. 1), roller 5 is placed with outstanding from cut portion 3 a little, and rest guide rod (in the time being inserted through slit 2) above, thereby cause limiting a supporting directrix of tool rack 1.Thus, in a slit, define two relative static directrixes of guide rod, thus limit lateral movement: on the one hand, the inner surface 2 ' of tool rack, and, on the other hand, the bus of roller 5.When therefore tool rack between moving period, will produce transverse guidance on guide rod, it can slide on the one hand, rolls on the other hand.
During tool rack slides on guide rod, in order to complete the maximum support of roller 5 on guide rod, in the various swing attitudes that can take at described tool rack, the axis of rotating dog 6 is arranged according to the angle that is no more than 30 degree with respect to axis of support, that is to say, this axis during engraving step through instrument R and perpendicular to ceramic tile.This attitude makes, and the rotation of pin 6 keeps being mainly orthogonal to the direction of advance of tool rack during carving, and therefore, roller cooperates with guide rod with almost desirable rotation mode.
Due to the past along with the time, the wearing and tearing that produce by sliding have reduced the diameter of roller 5, the roller certainly slidingsurface 2 ' in guide rod and slit weares and teares before, therefore can act on fastening and adjustment screw 8a and 8b, support is shifted near slightly to tool rack main body 1a, thereby overcome the reaction of spring assembly (for example, Belleville washer).By this way, even can controlled mode recover little lax, described little lax may due to the diameter of roller 5 reduce be created in slit.
Consider the guidance accuracy that can reach in any state of wear of tool rack, for instrument, also preferably suitably form and think the accuracy that himself realizes identical magnitude.
For this purpose, according to a preferred variation, tool rack is equipped with lubricating system, for example, and the lubricating system of describing in the Italian utility model NO.270567 with the applicant's name application.
Particularly, preferably, on the same side for the support of device for installing and adjusting, recessed and microscler seat portion is set in order to receive compressible tank 10, described compressible tank 10 is used as lubricating can.
Tank 10 can obtain by molded thin plastic sheet, and has smooth wall, alternatively on this smooth wall, is furnished with the wall of thin type, to form a kind of semicylindrical bottle.In one end of columnar bottle, be provided with short transfer passage, this bottle has bottleneck 10a, and this bottleneck prevents that in the situation that not having overvoltage oil from flowing from columnar bottle.At the other end place of transfer passage, define the 10b of cone-shaped chamber with spout 10c, on the summit of the 10b of this cone-shaped chamber, be formed with oil transportation hole.As shown in drawings, tank 10 is arranged on by simple joint in the seat portion of tool rack, note the chamber with spout to be arranged on bottom, and sprocket hole is inserted in transfer passage 11.Described passage 11 obtains in the thickness of tool rack main body 1a, and connects the bottom of fangs and the seat portion (Fig. 6) of actual instrument (the wheel R that, hard metal is made).
Therefore to be arranged to the seat portion of tank 10 itself be microscler to preferred device, and have from the rotation of wheel R and radially extend out and towards the longitudinal axis of the main body 1a of tool rack.
In the situation that there is no tank 10, the transfer passage 11 that leads to the outside of tool rack can also be used for introducing the delivery end of oil feeder.On the contrary, in the time that tank exists and is provided with oil, the lubricated of engraving wheel R can easily be realized by promoting a little flexible bottle, to increase the pressure in it and force oil to overcome the bottleneck in transfer passage temporarily, until flow out sprocket hole.
Preferably verified, can be by providing conveying lever 12 to improve above-mentioned layout.In fact, according to environmental condition, bottleneck 10a and the 10b of cone-shaped chamber are set and may be not enough to prevent the freely transferring oil from spout 10c, this may cause the too early consumption of the lubricating oil of drum-shaped chamber 10.Bar 12 is the form of thin semi-rigid core, has the diameter that is slightly smaller than nozzle holes 10c, but also is equipped with porous surface, and this porous surface can be from the 10b of cone-shaped chamber oil suction, and by capillarity, oil is delivered to the other end.Preferably, bar 12 is made up of the stranded core of the metal that is equipped with soft bristle, and example is bristle pipe cleaner as is known.
Bar 12 is incorporated in passage 11, and wherein one end contacts with cutting wheel R, and the other end is inserted in the 10b of cone-shaped chamber, thus close jet hole 10c partly.
Be proved to be outstanding, bar 12 is transported to cutting wheel R by capillarity by the oil of appropriate amount, thereby prevents that oil from overflowing from tank 10.
Fig. 7 A to Fig. 7 C shows the installation steps that tank 10 are mounted to tool rack: first, according to the direction of aiming at the central axis of passage 11, bar 12 is inserted in nozzle holes 10c; Then, tank is rotated into and is assemblied in its portion, meanwhile, bar 12 is bent to certain angle.
Should be able to be expressly understood from the above description, allow ideally to realize according to device of the present utility model the object that preface proposes.Particularly, can easily be regulated according to tool rack of the present utility model, and therefore, can be along with the time keep in the past its slip precision on guide rod.The correction lubricated (being provided with the suitable lubricating coupler being embedded in tool rack) of also taking turns by engraving as one man and has synergistically realized the accuracy of engraving.
But, should be understood that, protection domain of the present utility model is not restricted to the above concrete structure providing, but can extend to any other structure that can realize same function.
Particularly, although shown the preferred form of device, do not get rid of the supporting bracket that backing roll can be all set in the both sides of tool rack.In view of its cost bringing and complexity, doubling of adjusting device is not strict essential, although it allows to realize the more advantages aspect degree of regulation and symmetry.
