Description

  The present invention provides a guide device used for a linear guide part or a curved guide part of a machine tool or various industrial robots on a track rail of the guide device when laying on a base part such as a bed or a column of the machine device. The present invention relates to a jig for continuously temporarily fixing or continuously driving a closing cap to a plurality of bolt mounting holes.

  Conventionally, as a guide device constituting a guide portion of a machine tool or various industrial robots, a linear or arc-shaped track rail having a ball rolling surface formed along the longitudinal direction, and a number of the track rails are provided. What is comprised from the movement block assembled | attached via the ball | bowl is known. The moving block has a load rolling surface facing the ball rolling surface of the track rail, and a large number of balls rolling while applying a load between the load rolling surface and the rolling surface of the track rail. A circulation path for infinite circulation is provided. By circulating the ball in the infinite circulation path, the moving block can continuously move over the entire length of the track rail.

  Usually, the track rail is fixed by fastening a fixing bolt to a base portion such as a bed or a column of a machine tool or the like. For this reason, a bolt mounting hole for allowing the fixing bolt to pass through at a predetermined interval along the longitudinal direction is formed through the track rail. If the head of the fixing bolt protrudes on the track rail, it becomes an obstacle when the moving block moves along the track rail, so the inside of the bolt mounting hole is formed in two steps, a small diameter portion and a large diameter portion. The small diameter portion is formed with an inner diameter slightly larger than the nominal diameter of the bolt, and the large diameter portion is formed with an inner diameter slightly larger than the bolt head. That is, the large diameter portion serves as a housing portion for the bolt head, and the bolt head is prevented from projecting to the surface of the track rail.

  On the other hand, in order to prevent foreign matter adhering to the track rail from entering the inside of the moving block, a seal member that is in sliding contact with the track rail is provided around the moving block. These seal members eliminate foreign matter adhering to the surface of the track rail as the moving block moves. If a bolt mounting hole is provided in the track rail, the foreign matter is moved through the bolt mounting hole. There is a possibility of intruding inside. Further, since the seal member is in contact with the surface of the track rail with a certain tightening force, if there is a bolt mounting hole, the tip end portion of the seal member rubs against the opening edge of the bolt mounting hole. There is also an inconvenience that the member deteriorates early.

  For this reason, when the guide device is used in an environment in which foreign matter is likely to adhere to the track rail, for example, as shown in Patent Document 1, a closing cap is press-fitted into the bolt mounting hole of the track rail, The bolt mounting hole is closed with a closing cap. As a specific press-fitting method, after lightly pushing the end of the closure cap into the bolt mounting hole, place the backing plate on the closure cap, repeatedly hitting the backing plate with a tool such as a hammer, etc. A method of completely burying in the mounting hole is employed. Accordingly, it is expected that the upper surface of the closing cap press-fitted into the bolt mounting hole is flush with the surface of the track rail, thereby enhancing the sealing between the seal member and the track rail.

WO2015 / 033486

  In driving the blocking cap into the bolt mounting hole, it is necessary to first perform a temporary fixing operation to lightly push the blocking cap into each bolt mounting hole. If the closing cap is press-fitted with the bolt mounting hole tilted, the outer periphery of the closing cap is slightly scraped off to generate shavings (burrs). It will be necessary to carry out in addition. For this reason, in the temporary fixing operation, it is necessary to push the closing cap straight into the bolt mounting hole, but since there are a plurality of bolt mounting holes along the longitudinal direction of the track rail, the temporary fixing operation of the blocking cap is performed. If this is done carefully, there is a problem that the working time for one track rail becomes long.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a closure cap without causing unevenness of operation for a plurality of bolt mounting holes provided in a track rail of a guide device. It is an object of the present invention to provide a temporary fixing jig for a closing cap that can be temporarily fixed continuously.

  Another object of the present invention is to provide a closing cap driving jig capable of quickly and continuously driving a closing cap into a plurality of bolt mounting holes without causing uneven operation. .

  That is, the present invention is a jig for continuously temporarily closing a closing cap with respect to a plurality of bolt mounting holes provided at predetermined intervals on a track rail of a guide device. A guide body assembled via a moving body and movable relative to the track rail; a cap loading hole fixed to the guide body and opposed to the bolt mounting hole; and a plurality of cap loading holes in the cap loading hole A stack member for accumulating and accommodating a closure cap, and a guide groove that is fixed to the guide body and that forms a wedge-shaped space along the longitudinal direction of the track rail, are provided on the track rail from the cap loading hole. A push-in member that introduces the supplied closure cap into the wedge-shaped space as the guide body moves, and presses the closure cap against the bolt mounting hole. There.

  Further, the driving jig of the present invention has a finishing function added to the temporary fixing jig, and further includes a closing cap pressed against the track rail and pressed into the bolt mounting hole by the pressing member. A finishing member that is pressed to embed the blocking cap in the bolt mounting hole is provided.

  According to the temporary fixing jig of the present invention, the closing cap is supplied onto the track rail from the cap loading hole as the guide body moves with respect to the track rail, and the pushing member moves the blocking cap against the bolt mounting hole. Since the pressing is performed, the closing cap can be temporarily and temporarily fixed to a plurality of bolt mounting holes provided in the track rail.

  According to the present invention, the closing member is embedded in the bolt mounting hole with the closure cap temporarily fixed to the bolt mounting hole, so that the plurality of bolt mounting holes provided in the track rail are Thus, the closure cap can be driven quickly and continuously.

  Furthermore, since the guide body travels with a certain accuracy with respect to the track rail, such accuracy is reflected in the pushing of the closing cap by the jig, and temporarily fixes the plurality of closing caps to the bolt mounting holes without unevenness of work. Alternatively, it can be completely driven.

  Hereinafter, a temporary fixing jig and a driving jig for a closure cap of a bolt mounting hole according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 shows an example of a guide device to which a temporary fixing jig and a driving jig for a closing cap according to the present invention can be applied. This linear guide device is composed of a track rail 1 disposed on a base portion such as a bed, and a moving block 2 assembled to the track rail 1 through a number of rolling elements (balls or rollers) 3. The moving block 2 can move freely on the track rail 1.

  The track rail 1 is formed in a substantially rectangular cross section, and a total of four rolling surfaces 10 along which the rolling elements roll are formed along the longitudinal direction. Two rolling surfaces 10 are formed on each side surface of the track rail 1, and there are an obliquely upward rolling surface and an obliquely downward rolling surface. The track rail 1 is formed with a plurality of bolt mounting holes 11 at appropriate intervals in the longitudinal direction, and the track rail 1 is covered by fixing bolts (not shown) inserted into the bolt mounting holes 11. It is fixed on the base part which is a mounting surface.

  On the other hand, the moving block 2 is fixed to a block body 4 having a mounting surface 41 of a movable body such as a table and a tap hole 42 into which a fixing bolt of the movable body is screwed, and both front and rear end faces of the block body 4. The lid 5 is fixed to the block body 4 so that an infinite circulation path for the rolling elements is provided in the moving block 2. . The rolling element applies a load between the track rail and the block body 4 while circulating in the endless circuit. Further, a seal member 6 slidably mounted on the track rail 1 is attached to the lid 5, and dust or the like adhering to the track rail 1 is moved into the moving block 2 as the moving block 2 moves. Preventing intrusion.

  FIG. 2 is a cross-sectional view showing a state in which the track rail 1 is fixed on the base portion 8 using the fixing bolt 7, and the left-right direction in FIG. 2 corresponds to the longitudinal direction of the track rail 1. As shown in the figure, a bolt mounting hole 11 for inserting the fixing bolt 7 through the track rail 1 is formed in two stages of a small diameter portion 11a and a large diameter portion 11b, and the fixing bolt 7 is tapped on the base portion 8. When fastened to the hole 80, the head of the fixing bolt 7 is accommodated in the large-diameter portion 11 b of the bolt mounting hole 11. For this reason, hexagon socket head bolts are used as the fixing bolts 7.

  In order to prevent foreign matter from entering the bolt mounting hole 11 during use of the linear guide device, after the fastening of the fixing bolt 7 is completed and the track rail 1 is fixed to the base portion 8, a disk is inserted into the bolt mounting hole 11. A cylindrical cap 70 is press-fitted so that the large-diameter portion 11 b of the bolt mounting hole 11 is blocked above the fixing bolt 7. Thereby, the adhesiveness with respect to the track rail 1 of the sealing member 6 fixed to the front and rear ends of the moving block 2 in the moving direction is improved, and foreign matter enters the moving block 2 from the outside, or from the moving block 2 to the outside. It is possible to prevent the lubricant from leaking out as much as possible. Since the track rail 1 is made of steel, the closing cap 70 is made of a material having a hardness lower than that of the track rail 1. For example, synthetic resin such as polyacetal (POM), metal such as gun metal and aluminum, etc. Is used.

  The maximum outer diameter of the closing cap 70 is set to be slightly larger than the inner diameter of the large diameter portion 11b of the bolt mounting hole 11, and the closing cap 70 is adapted to the opening edge of the bolt mounting hole 11 to moderately When pressed, the closing cap 70 is temporarily fixed in a state of protruding onto the track rail 1 without sinking into the bolt mounting hole 11. When a larger pressing force is applied to the blocking cap 70 temporarily fixed to the bolt mounting hole, the blocking cap 70 sinks into the large-diameter portion 11b of the bolt mounting hole 11, and the top plate surface of the blocking cap 70 71 and the upper surface 12 of the track rail 1 form a continuous plane. Thereby, the mounting of the closing cap 70 to the bolt mounting hole 11 is completed.

  In the temporary fixing jig of the present invention, after the track rail 1 is fastened to the base portion 8 using the fixing bolt 7, the closing cap 70 is continuously connected to the plurality of bolt mounting holes 11 of the track rail 1. Used for temporary fixing.

  FIG. 3 shows an example of an embodiment of a temporary fixing jig to which the present invention is applied. The temporary fixing jig 9 includes a guide member 90 assembled to the track rail 1 through a large number of rolling elements, and a stack member 91 that is fixed to the guide member 90 and stores a plurality of closing caps 70 in a stacked manner. And a pushing member 92 that is fixed to the guide body 90 and presses the closing cap 70 supplied from the stack member 91 onto the track rail 1 against the bolt mounting hole 11. In FIG. 3, the temporary fixing jig 9 is drawn in half along the longitudinal direction of the track rail 1 so that the internal structure of the temporary fixing jig 9 can be easily grasped.

  The guide body 90 is assembled to the track rail 1 through a large number of rolling elements, and can freely move along the track rail 1. The guide body 90 is formed using the moving block 2. However, in FIG. 3, the pair of lids 5 attached to the moving block 2 is omitted, and only the portion corresponding to the block main body 4 is drawn. A through hole for supplying the closing cap 70 to the track rail 1 is formed in the center of the guide body 90. The through hole is provided at a position facing the bolt mounting hole 11 when the guide body 90 is moved along the track rail 1.

  The stack member 91 includes a cartridge case 91a in which the closing cap 70 is accommodated, and a holder 91b for mounting the cartridge case 91a to the guide body 90. The cartridge case 91a is detachable from the holder 91b. By replacing the cartridge case 91a, a plurality of closing caps 70 can be easily supplied to the temporary fixing jig 9. Yes.

  Note that the stack member 91 is not necessarily composed of the cartridge case 91a and the holder 91b, and the closing cap 70 is provided for each stack member 91 in which the cartridge case 91a and the holder 91b are integrated. You may make it load by work.

  The cartridge case 91a is formed in a cylindrical shape, and a loading hole for stacking and storing a plurality of closing caps 70 penetrates vertically. The closing cap 70 is packed into the loading hole from the upper end of the cartridge case 91a, and is supplied onto the track rail 1 from the lower end of the loading hole. A holding claw that is curved toward the center of the loading hole is provided around the loading hole at the lower end of the cartridge case 91a, and the closing cap 70 is prevented from falling out of the loading hole by the holding claw. Has been. A lid member 91c for closing the loading hole is fixed to the upper end of the cartridge case 91a, and a coil spring 91d is provided between the lid member 91c and the closure cap 70. Therefore, the closing cap 70 is stacked in the loading hole in a state of being biased toward the holding claw.

  On the other hand, the holder 91b is provided with a cylindrical support portion 90a for supporting the cartridge case 91a. When the cartridge case 91a is inserted into the support portion 90a, the lower end of the cartridge case 91a is inserted into a through hole provided in the center of the guide body 90, and the blocking cap 70 stored in the cartridge case 91a is moved through the track. It can be supplied on the rail 1.

  FIG. 4 is a perspective view showing the pushing member 92. The pushing member 92 is a plate-like member that is slightly narrower than the width of the track rail 1 and is elongated along the longitudinal direction of the track rail 1, and the track provided with the bolt mounting holes 11. It is arranged in the gap between the upper surface of the rail 1 and the guide body 90. A tap hole 92a into which a mounting bolt is screwed is formed on the surface of the pushing member 92 facing the guide body 90. A cap receiving hole 92b is provided in the center of the pushing member 92, and the closing cap 70 supplied from the stack member 91 is dropped into the cap receiving hole 92b. An annular raised portion 92 c is provided around the cap receiving hole 92 b facing the guide body 90. When the cartridge case 91a is attached to the holder 91b, the holding claw located at the lower end of the cartridge case 91a comes into contact with the pushing member, and the raised portion 92c pushes the holding claw outward in the radial direction of the cartridge case 91a. Press towards. As a result, the holding cap 70 held by the holding claw is released, and the closing cap 70 is dropped from the cartridge case 91a into the cap receiving hole 92b.

  FIG. 5 is a view showing a bottom surface 92 e of the pushing member 92 facing the track rail 1. A concave groove-shaped guide groove 92d is provided on the bottom surface 92e of the push-in member 92. The guide groove 92d allows the closure cap 70, which has been dropped into the cap receiving hole 92b from the cartridge case 91a, to pass through the track rail 1. The function of pushing into the bolt mounting hole 11 is exhibited. The guide groove 92d is adjacent to the cap receiving hole 92b, is deepest at the connecting portion with the cap receiving hole 92b and has a wide groove width, and becomes shallower and narrower as the distance from the cap receiving hole 92b increases. That is, a wedge-shaped space that gradually narrows along the longitudinal direction of the track rail is formed between the track rail and the guide groove.

  As shown in FIG. 6, when the guide groove 92d is observed from the longitudinal direction of the push-in member 92, the entrance of the guide groove 92d opened in the cap receiving hole 92b is the center in the width direction of the push-in member 92. The depth is deepest and gradually becomes shallower as it approaches both ends of the pushing member 92. In FIG. 4, the bottom surface 92e formed on a plane is hatched so that the boundary between the bottom surface 92e of the pushing member 92 and the guide groove 92d is clear.

  The bottom surface 92e of the pushing member 92 is not in contact with the track rail 1 in a state where the pushing member 92 is fixed to the guide body 90, and a gap is formed between them. When the pushing member 92 is moved in the longitudinal direction of the track rail 1 together with the guide body 90, the closing cap 70 is pushed by the guide groove 92d and pushed into the bolt mounting hole of the track rail 1. However, since there is a gap between the bottom surface 92e of the pushing member 92 and the track rail 1, the closing cap 70 is not completely pushed into the bolt mounting hole 11, and the upper portion of the closing cap is The temporarily fixed state slightly protrudes on the track rail.

  A two-dot chain line in FIG. 6 shows the closing cap 70 placed on the track rail 1, and shows a state before the closing cap 70 is temporarily fixed to the bolt mounting hole 11. The size of the entrance of the guide groove 92d that opens in the cap receiving hole 92b is set to be slightly larger than the outer shape of the closing cap 70 in contact with the track rail 1 (two-dot chain line in FIG. 6). Yes. Therefore, when the pushing member 92 is moved on the track rail 1, the closing cap 70 in contact with the track rail 1 does not get caught on the inner peripheral wall of the cap receiving hole 92b, and does not enter the guide groove 92d. You can enter.

  On the other hand, the size of the entrance of the guide groove 92d opened in the cap receiving hole 92b is set smaller than the size of the two closed caps 70 stacked on the track rail 1. Therefore, when a plurality of closing caps dropped from the cartridge case 91a are stacked on the track rail 1, when the pushing member 92 is moved on the track rail 1, the lowermost closing cap The second closing cap 70 stacked on the 70 (first closing cap) is caught by the inner peripheral wall of the cap receiving hole 92b and cannot enter the guide groove 92d. That is, when the temporary fixing jig 9 is moved on the track rail 1, the first closing cap that is in contact with the track rail 1 among the plurality of closing caps 70 stacked in the cap receiving hole 92b. Only 70 is pushed into the bolt mounting hole 11 of the track rail 1 by the guide groove 92d.

  Further, as shown by a one-dot chain line in FIG. 5, when the first closing cap 70 is not yet pushed into the bolt mounting hole 11 and is present in the guide groove 92d, the second closing cap 70 70 partially overlaps with the first closing cap 70, and the second closing cap 70 is configured to exist inside the cap receiving hole 92 b without contacting the track rail 1. .

  Next, an operation of temporarily fixing the closing cap to the bolt mounting hole 11 of the track rail using the temporary fixing jig 9 will be described.

  After the work of fixing the track rail 1 of the guide device to the base portion 8 is completed, before the moving block 2 of the guide device is assembled to the track rail 1, first, the temporary fixing jig 9 is attached to the track. Mount on rail 1. The temporary fixing jig 9 is attached to the track rail 1 by assembling the guide body 90 to the track rail 1 from the end in the longitudinal direction of the track rail 1. Thereby, the temporary fixing jig 9 can freely move along the track rail 1.

  Next, the cartridge case 91a is inserted into the support portion 90a of the holder 91b. As shown in FIG. 7, a holding claw 91e is provided at the lower end of the cartridge case 91a, and when the cartridge case 91a is inserted into the support portion 90a of the holder 91b, the closing cap 70 has the holding claw 91e. Is held in the cartridge case 91a. When the cartridge case 91a is pressed toward the track rail 1 from this state, the holding claws 91e located at the lower end of the cartridge case 91a are inserted into the cap receiving holes 92b of the pushing member 92 as shown in FIG. Abut against the periphery. At this time, the holding claw 91e is pressed outwardly in the radial direction of the cartridge case 91a by a raised portion 92c provided around the cap receiving hole 92b, and the holding claw 91e is displaced to displace the closing cap 70. The dropout regulation is lifted. Thereby, the plurality of closing caps 70 in the cartridge case 91a are dropped into the cap receiving holes 92b of the pushing member 92 in a stacked state.

  When the closing cap 70 is thus supplied from the cartridge case 91a onto the track rail 1, the temporary fixing jig 9 is moved along the track rail 1 in the direction of the arrow A as shown in FIG. Move. As a result, the first closing cap 70 a in contact with the track rail 1 enters the guide groove 92 d of the pushing member 92. At this time, the second closing cap 70b is locked to the inner peripheral surface of the cap receiving hole 92b, does not enter the guide groove 92d, and is stacked on the first closing cap 70a. The second closing cap 70 b is not in contact with the track rail 1.

  When the temporary fixing jig 9 is further moved in the direction of arrow A from this state, the first closing cap 70a that has entered the guide groove 92d is pressed toward the upper surface 12 of the track rail 1 by the pushing member 92. When the bolt mounting hole 11 of the track rail 1 reaches just below the guide groove 92d, the closing cap 70a is pushed into the bolt mounting hole 11 of the track rail 1. Then, as shown in FIG. 10, when the guide groove 92 d has passed over the bolt mounting hole 11, the closing cap 70 a is pushed into the large diameter portion 11 a of the bolt mounting hole 11.

  However, as described above, in the temporary fixing jig 9 of this embodiment, since a gap is provided between the bottom surface 92e of the pushing member 92 and the top surface 12 of the track rail, as shown in FIG. The upper portion of the closing cap 70 a pushed into the bolt mounting hole 11 slightly protrudes from the upper surface 12 of the track rail 1. Therefore, a separate finishing operation is required to completely push the closing cap 70 into the bolt mounting hole 11 so that the top plate surface 71 of the closing cap 70 and the upper surface 12 of the track rail 1 are matched.

  On the other hand, as shown in FIG. 10, when the first closing cap 70a is pushed into the bolt mounting hole 11, the overlap between the first closing cap 70a and the second closing cap 70b is eliminated, The second closing cap 70 b enters the guide groove 92 d of the pushing member 92. Thereby, the preparation which pushes in a closure cap with respect to the 2nd bolt attachment hole which exists in the advancing direction (arrow line A direction) of the said guide body 90 is completed. At this time, the third closing cap is locked to the inner peripheral surface of the cap receiving hole 92b, does not enter the guide groove 92d, and is stacked on the second closing cap 70a.

  Therefore, when this temporary fixing jig 9 is used, the temporary fixing jig 9 is moved only in one direction along the track rail 1, and the plurality of closing caps 70 incorporated in the stack member 91 are moved to the track. It becomes possible to temporarily fix the plurality of bolt mounting holes 11 existing in the rail 1 continuously.

  At this time, since the movement accuracy of the guide body with respect to the track rail is equivalent to that of the movement block in the guide device, the position accuracy of the pushing member with respect to the bolt mounting hole reflects the movement accuracy of the guide body. It becomes possible to push the closing cap into each of the plurality of bolt mounting holes without any work and temporarily fix it.

  Further, the guide groove 92d is formed in a concave curved shape along the width direction of the track rail 1, and is deepest at the center in the width direction of the pushing member 92 and gradually approaches the both end portions of the pushing member 92. When the closing cap 70 is pushed into the bolt mounting hole 11 with the movement of the guide body 90, the guide groove 92d is in contact with two places near the diameter portion of the closing cap 70, as the guide body 90 moves. The closing cap 70 is pressed. Therefore, when the closing cap 70 is pushed into the bolt mounting hole 11 of the track rail 1, it is possible to prevent the closing cap 70 from being pressed in a tilted state as much as possible. Therefore, it is possible to prevent a problem that the ceiling surface 71 of the closing cap 70 is inclined with respect to the upper surface 12 of the track rail 1 at the time of temporary fixing. It is possible to prevent a problem in which the periphery of the cap 70 is partially cut off and burrs are generated.

  In addition, the linear guide apparatus shown in FIG. 1 is an illustration, Comprising: The guide apparatus which can apply the press-fitting jig of this invention is not restricted to this.

  In the embodiment described above, the guide groove 92d of the push-in member 92 is provided only on one side of the cap receiving hole 92c, and the temporary fixing jig 9 is indicated by the arrow A in FIG. It is possible to push the closing cap into the bolt mounting hole only when it is moved in the direction. However, if a pair of guide grooves 92d are provided opposite to each other with the cap mounting hole 92c interposed therebetween, the closure cap 70 can be bolted even when the temporary fixing jig 9 is moved in the anti-A direction. It can be pushed into the mounting hole 11.

  Next, a closing cap driving jig to which the present invention is applied will be described.

  In the temporary fixing jig 9 described with reference to FIGS. 3 to 11, the pushing member 92 is not in contact with the track rail 1, and the pushing member 92 is formed in the bolt mounting hole 11 of the track rail 1. Even when passing directly above, the closing cap 70 is not completely pushed into the bolt mounting hole 11, and the closing cap 70 is in a temporarily fixed state protruding slightly on the track rail 1. The driving jig of the present invention is an extension of the temporary fixing jig 9 described above, and a closing cap 70 temporarily fixed to the bolt mounting hole 11 by the pushing member 92 is attached to the bolt mounting hole 11. A finishing member for embedding is provided.

  FIG. 12 is a sectional view showing an example of a closing cap driving jig to which the present invention is applied. The driving jig 100 is obtained by adding a finishing member 93 to the temporary fixing jig 9 described above, and the configuration other than the finishing member 93 is substantially the same as the temporary fixing jig 9. However, a pair of guide grooves 92d are provided in the pushing member 92 in opposite directions with the cap mounting hole 92c interposed therebetween, and the driving jig 100 can be moved in any direction along the longitudinal direction of the track rail 1. Even when it is moved, the closing cap 70 can be pushed into the bolt mounting hole 11. Therefore, among the configurations of the driving jig 100, the same configurations as those of the temporary fixing jig 9 described above are denoted by the same reference numerals as those of the embodiment of the temporary fixing jig 9 in FIG. Description of is omitted.

  A pair of finishing members 93 are provided on the guide body 90 that is freely movable along the track rail 1. These finishing members 93 are arranged so as to sandwich the pushing member 92 with respect to the longitudinal direction of the track rail 1 (left and right direction in FIG. 12). Each finishing member 93 is a roller that is pivotally supported by the guide body 90, and the axial direction of the rotation shaft of the finishing member 93 matches the width direction of the track rail 1 (the depth direction in FIG. 12). The outer peripheral surface of each finishing member 93 formed in a roller shape is in pressure contact with the upper surface 12 of the track rail 1 in which the bolt mounting hole 11 is formed, and when the guide body 90 moves along the track rail 1. The finishing member 93 rolls on the upper surface 12 of the track rail 1. The axial length of the finishing member 93 is set larger than the diameter of the bolt mounting hole 11, that is, the diameter of the closing cap 70.

  When the driving jig 100 is moved along the longitudinal direction of the track rail 1, it is dropped onto the track rail 1 from the cap receiving hole 92 b of the pushing member 92, as with the temporary fixing jig 9. The closing cap 70 enters the guide groove 92d of the pushing member 92, and when the bolt mounting hole 11 reaches just below the guiding groove 92d, the closing cap 70 is pushed into the bolt mounting hole 11 of the track rail 1. It is. Since a gap is provided between the bottom surface 92e of the pushing member 92 and the top surface 12 of the track rail, the closing cap 70 is not pushed completely into the large diameter portion 11a of the bolt mounting hole 11, The upper part is in a temporarily fixed state in which the upper surface 12 of the track rail 1 slightly protrudes.

  In the driving jig 100 of this embodiment, since the finishing member 93 is disposed adjacent to the pressing member 92, when the driving jig 100 is further moved with respect to the track member 1, The finishing member 93 rides on the top plate surface 71 of the closing cap in the temporarily fixed state, rolls on the top surface 71, and presses the closing cap 70 against the bolt mounting hole 11. Since the finishing member 93 is supported by the guide body 90 and pressed against the upper surface 12 of the track rail 1, when the finishing member passes over the closing cap, the closing cap enters the bolt mounting hole 11. The top plate surface 71 of the closing cap 70 and the upper surface 12 of the track rail 1 are matched to form a single surface.

  For this reason, only by moving the driving jig 100 in one direction along the track rail 1, a plurality of closing caps 70 built in the stack member 91 are connected to a plurality of bolt mounting holes existing in the track rail 1. It is possible to embed the blocking cap 70 in the bolt mounting hole 11 by temporarily temporarily fixing the belt 11 and performing a finishing driving operation.

  Further, in the driving jig 100 shown in FIG. 12, since the pair of guide grooves 92d and the pair of finishing members 93 are provided with the cap mounting hole 92c interposed therebetween, the driving jig 100 is used as the track rail 1. The closure cap 70 accommodated in the stack member 91 is continuously temporarily fixed to the bolt mounting hole 11 of the track rail 1 and further finished. Work can be done.

  Therefore, if the driving jig 100 for the closing cap 70 of the present invention is used, the closing cap 70 can be quickly and continuously applied to the plurality of bolt mounting holes 11 arranged in the track rail 1 without causing unevenness of work. It is possible to drive and match the top plate surface 71 of the closing cap 70 and the upper surface 12 of the track rail 1 without any step.

  The axial length of the finishing member formed in a roller shape is set to be larger than the diameter of the bolt mounting hole 11, and even if the closing cap 70 is not present, the finishing member 93 is Since it is possible to pass directly above the bolt mounting hole 11, the driving jig 100 can freely move in any of the longitudinal directions with respect to the track rail 1.

  In the driving jig 100 according to the present invention, the finishing member 93 may be any member as long as it presses the closing cap 70 in a temporarily fixed state while being pressed against the track rail 1, The shape of the finishing member 93 is not limited to the roller shape shown in FIG. For example, as shown in FIG. 13, a convex curved finish surface 93a that is curved along the longitudinal direction of the track rail 1 is provided adjacent to the guide groove 92d of the pushing member, and the finish surface 93a is provided to the finish member. 93 may be pressed against the upper surface 12 of the track rail 1. Further, by setting the width of the finished surface 93a that matches the width direction of the track rail 1 to be larger than the diameter of the bolt mounting hole 11, the finished surface can be obtained even when the closing cap 70 is not present. Since 93a can pass directly above the bolt mounting hole 11 without being caught by the bolt mounting hole 11, the driving jig 100 can freely move in any of the longitudinal directions with respect to the track rail 1. Is possible.

  Further, in the driving jig 100 shown in FIG. 12, a pair of guide grooves 92d and a pair of finishing members 93 are provided across the cap mounting hole 92c, and the driving jig 100 is arranged in the longitudinal direction of the track rail 1. In any direction, the closing cap 70 can be driven in, but the guide groove 92d and the finishing member may be provided only on either side of the cap mounting hole 92c. Good. In this case, the driving jig functions only when moved on the track rail 1 in one direction, and drives the closing cap 70 into the bolt mounting hole 11.
