In any case, the ball clamp holder of this chain form or ball shielding can, it as fuse, utilizes ball resin to annotate the shrinkable characteristic in back at mould when moulded resin, and ball can be rotated.According to different types of resin, need considerable time just can make ball realize turnability sometimes, sometimes may not realize turnability stably, also then can not realize turnability sometimes.
The invention solves the clamp holder of the traditional rolling element of utilization or the difficulty of shielding can, the ball shielding can of chain form or the problem that the ball clamp holder exists have been solved, proposed above this point, the purpose of this invention is to provide a kind of endless clamp holder and manufacture method thereof, not only make this clamp holder can be very easy to make, and, rolling element can not break away from, utilization is got up and also is very easy to, and available automatic mode is assembled to clamp holder in the guiding device and goes, and rolling element can rotate reliably very reposefully.
Summary of the invention
Thus, according to one aspect of the present invention, provide a kind of endless clamp holder of guiding device, this endless clamp holder comprises: several rolling elements, and it is arranged in predetermined interval, at the interior side roll of the track of an endless; Resin connector with a flexibility, it has spacer portion and linking department, spacer portion is spaced apart corresponding rolling element, linking department then links together these spacer portion, to keep these rolling elements to be in alignment and can rotate, this resin connector is to make with the method for injection moulding, rolling element is then as fuse, the size changing rate of the resin that is adopted before and after absorption oil or suction is greater than shaping shrinkage rate, have between resin connector and rolling element at interval, this gap is to produce after the processing that absorbs oil or water.
Further, according to another aspect of the present invention, a kind of manufacture method of endless clamp holder is provided, annotate the resin connector with mould, this resin connector is keeping several rolling elements, the method that mould is annotated is as fuse rolling element, the resin that is adopted is after the processing through absorption oil or water, its size changing rate is greater than shaping shrinkage rate, between resin connector and corresponding rolling element, has the gap, rolling element is rotated, method be the resin connector after in mould, taking out, carry out the processing of oil suction or suction.
According to the present invention, be used for mould to annotate the resin of resin connector, must be a kind of before and after through the processing that absorbs oil or water, its size changing rate is greater than the resin of shaping shrinkage rate.Through absorbing the poor of size changing rate before and after the processing of oil or water and shaping shrinkage rate, be preferably in 0.1～2.0% the scope, more particularly 0.5～1.5%.Size changing rate before and after absorbing oil or water treatment is when the difference of shaping shrinkage rate is in 0.1～2.0% scope, and rolling element can have extraordinary rotating property, owing between resin connector and the rolling element, after oil suction or water treatment, produced the interval really.In addition, it is excessive big that size changing rate before and after oil suction or water treatment becomes, and when having surpassed shaping shrinkage rate big or small, consider the problem that rolling element spins off from the resin connector before and after oil suction or suction processing, yet according to inventor's experiment, the difference maximum of this size changing rate and shaping shrinkage rate only reaches about 2～3%, do not worry under so big or small degree the problem that rolling element can spin off from the resin connector.
Here, size changing rate before and after oil suction or the water treatment is a percentaeg (elongation), this percentaeg is to calculate like this, that is: resin connector (endless clamp holder) is deducting the length (length handle before) of resin connector (endless clamp holder) before oil suction or water through the length after oil suction or the water treatment (length after handling), compare with the length of resin connector (endless clamp holder) before oil suction or water treatment (length before handling) again, and the shaping shrinkage is a numerical value of using the following formula according to JIS K6911.5.7 to calculate.
Shaping shrinkage rate={ (size of die size-formed article) ÷ die size } * 100
In addition, about being used for the resin of moulded resin connector, according to the present invention, the resin connector of die casting must move on the rolling element track of endless together reposefully with rolling element, and this endless track is the supporting surface of guiding device, for this reason, the resin of resin connector need have flexibility, the Shore hardnes figure of this resin is preferably in 35～75 the scope, and optimal hardness numerical value is 40～60.
Resin with such flexibility applicable to manufacturing resin connector, for instance, the elastomer that polyamide-based is arranged, as the elastomer of pebax (trade name of making by Toray company), polyester base, as the elastomer of the elastomer of the elastomer of Hytrel (trade name of making by Toray and Dupont company), the elastomer that also has polyurethane, styryl, alkylene and picture flexible PVC or the like.In addition, in these elastomers, consider size changing rate, anti-chemistry and specific elongation etc. after the characteristic of resin connector, particularly ductility and deformability, oil suction or the suction, polyamide-based or polyester based elastomeric are the materials that pushes away the most still.In addition, consider the time cycle, that is: after oil suction or suction processing, specific elongation reaches the full time of closing state, and in other words, the size change is the steady state time of (dimensionally stable time), and the elastomer of polyester base is only.
In addition, according to the present invention, use ball or roller as rolling element in the guiding device, ball is suitable in the endless clamp holder of guiding device of requirement smooth sliding, and roller then preferably is used on the endless clamp holder of the guiding device that need apply bigger load.
In the process of making the endless clamp holder, according to the present invention, adopted in oil suction or suction and handled the resin of the size changing rate of front and back greater than shaping shrinkage rate, the resin connector that keeps several rolling elements is used as the fuse mould to these rolling elements and is annotated and form, after the resin connector is taken out from mould, for rolling element rotates needed gap, between resin connector and corresponding rolling element, just formed, method is to make the resin connector stand oil suction or suction processing.
Here, about being carried out the injection mould notes as fuse, several rolling elements can adopt the method for injection molding of inserting described in each above-mentioned Japan Patent.These patents have: patent gazette No.JP-B-6-56181, patent gazette No.JP-A-5-52217, the patent gazette No.JP-A-5-126149 of Japanese unexamined, the patent gazette No.JP-A-5-196036 of Japanese unexamined and the patent gazette No.JP-A-5-196037 of Japanese unexamined of Japanese unexamined of the examination of Japan.
In addition, make corresponding rolling element can realize rotating in the endless clamp holder that mould is annotated about the processing of oil suction or suction, various ways can be arranged, a kind of is that an endless clamp holder that takes out from mould is dipped in oil or the water; The way that also has be mist of oil or water mist spray above the endless clamp holder that from injection molding, takes out; A kind of way is the endless clamp holder that takes out from mould, under predetermined heating and pressurized conditions, carries out oil suction or suction; Another way is that the endless clamp holder that takes out from injection molding is placed in the environment of high-temperature; Also can be placed on the endless clamp holder that from injection molding, takes out in the atmosphere, place one period predetermined time cycle, perhaps other acceptable way.However, the best way is, the endless clamp holder that takes out from injection molding is dipped in oil or the water goes, and best bet is that the endless clamp holder is immersed in the oil the inside.
In addition, or treatment conditions about oil suction under this condition or suction processing, can select suitable and suitable condition according to kind and other similar condition of the method for handling, the resin that adopted, for example, according to adopting the endless clamp holder is immersed in way in oil or the water, usually, under the condition of 50 ℃ of conventional soaking temperatures, the endless clamp holder is soaked a few minutes to several hrs, and this condition also will be according to the kind of resin and different certainly.
The processing of oil suction or suction is can rotate for the rolling element that makes the endless clamp holder that mould annotates, had turnability although handle rolling element by oil suction, rolling element is still assembled like before, to play the guiding role, for example on the rolling element endless clamp holder surface after treatment through the oil suction processing, adhere to one deck wet oil, equally, also can occur in the suction treatment surface that is dipped in the water, preferably be fitted on guiding device and get on refilling after wiping attached to lip-deep moist layer.
In the process that oil suction is handled, the oil that adopts can be lubricant oil, grease or the semisolid petroleum lubricant of liquid, other has greasy property and material can adopt, for example, wish most that the fluid lubricant that adopts is the lubricant oil with mineral oil based of greasy property, the lubricant oil of synthetic oil-base, the oiling agent of emulsified liquid base, the oiling agent of liquid metal base, water base oiling agent, and other oiling agent.
When oil suction or suction processing, the elongation before and after the endless clamp holder is handled, just, the elongation of resin connector, after the process regular hour, the state that can reach capacity, however, when oil suction or suction are handled, be not the state that the general requirements elongation will reach capacity, 0.1% just enough as long as elongation has met or exceeded at least, preferably meet or exceed the length before 0.3% the processing, simultaneously, rolling element can freely rotate with respect to the resin connector and get final product.
But, when being assembled to after oil suction or suction dispose, the endless clamp holder goes in the guiding device and when not reaching capacity state, for no reason the resin connector of clamp holder will extend after having absorbed the lubricant oil that is used in the guiding device, up to having reached saturation state.Therefore, consider that the endless clamp holder influences the danger that it slides reposefully in guiding device, correspondingly, oil suction or suction are handled preferably the elongation of endless clamp holder and are close to saturation state and carry out, just are assembled in the guiding device then and go.Correspondingly, according to this viewpoint, the resin that is adopted about the resin connector, consider productivity, the polyester based elastomeric has a relatively short time cycle makes the elongation state (dimensionally stable time) that reaches capacity when oil suction is handled, the time is shorter, so be very desirable.
In addition, according to endless clamp holder of the present invention, the chamfering targeting part is slightly all arranged at two ends of resin connector, when on the track of the endless of supporting surface, moving with guiding device, particularly when the fore-end of endless clamp holder moves to the path of change direction of endless track or when moving out from the path that changes direction, the endless clamp holder can be by chamfering targeting part leading by fore-end.
At end, resin connector two ends chamfering targeting part slightly is like this design, that is: the track of considering the endless that the supporting surface by guiding device constitutes is in the radius of curvature that changes place, direction path, determines the size of radius of curvature and shape thereof or the like.By the chamfering targeting part being set at end, resin connector two ends on slightly, in the reciprocatory motion of guiding device, the endless clamp holder can move forward and backward on any one direction very reposefully.
Furtherly, the length of the endless clamp holder that mould is annotated is to determine like this, that is: consider the length of the endless track of the guiding device that is adopted, when guiding device is that the track length of large scale and endless is when very big, the endless clamp holder can be divided into 2 sections, 3 sections or several sections, like this, the mould mold size of annotating this endless clamp holder just can reduce.In addition, in this case, under the situation that is divided into several endless clamp holders, slightly all be provided with the chamfering targeting part at the end at each resin connector two ends.
According to the present invention, when annotating the resin connector, mould makes fuse with rolling element, this resin connector is just supporting rolling element after taking out from mould, the resin connector shrinks according to the size of shrinkage, the resin connector will stand oil suction or suction is handled, and the resin connector expands according to size changing rate after oil suction or suction processing.In addition, size changing rate before and after oil suction or suction are handled is greater than shaping shrinkage rate, correspondingly, the swell increment of the part around the rolling element surpasses the size around the rolling element, consequently, produced the gap between rolling element and resin connector, like this, rolling element can have good turnability infalliblely.
