[0003] A rolling guide is currently disclosed, which includes a box body, the box body includes a flow channel running through the middle for the flow of rods, and the box body is also equipped with guide rollers for guiding the rods. Generally, two guide rollers are provided and the distance between the two guide rollers, that is, the diameter of the rod, needs to be ensured; the rod is guided to flow out from between the two guide rollers and the two guide rollers are ensured to be in contact with the rod to guide the rod to enter and exit the roller hole relatively accurately.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0027] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] The embodiment of the present application discloses a rolling guide which can still ensure accurate guidance of the rod after long-term use.

[0029] Reference Figure 1 and Figure 2A rolling guide includes a base 1, on which a box body 2 is installed. The box body 2 includes a flow hole 21 that runs through the middle for allowing rods to pass through. The left end of the flow hole 21 is a discharge port 212, and the right end of the flow hole 21 is a feed port 211. In order to facilitate the rods to enter the flow hole 21, a trumpet tube 3 connected to the feed port 211 is installed on the box body 2, and the trumpet tube 3 can accurately guide the rods to enter the flow hole 21.

[0030] Reference Figure 2 and Figure 3 A plurality of guide roller mechanisms 4 are installed on the box body 2 at one side of the discharge port 212. In the present embodiment, the number of the guide roller mechanisms 4 is three. A feeding area 22 for the rods to pass through is formed between the three guide roller mechanisms 4. The three guide roller mechanisms 4 are evenly arranged around the feeding area 22. The box body 2 is also equipped with a driving mechanism 5 connected to the three guide roller mechanisms 4. The driving mechanism 5 can drive the three guide roller mechanisms 4 to synchronously approach / move away from the feeding area 22.

[0031] Reference Figure 2 and Figure 3 The three guide roller mechanisms 4 have the same structure. Take the lowest guide roller mechanism 4 as an example: the guide roller mechanism 4 includes a fine-tuning assembly 41 installed on the box body 2. The fine-tuning assembly 41 is rotatably connected to a guide roller 42. The fine-tuning assembly 41 is configured to drive the guide roller 42 to approach / move away from the material feeding area 22. Specifically, the axis of each guide roller 42 is perpendicular to the axis of the material flow hole 21. Each guide roller 42 includes an inner concave ring portion 421 on the outer wall. The inner concave ring portion 421 is configured to be able to match with the outer circumferential wall of the rod.

[0032] After long-term use, the three guide rollers 42 may be evenly worn, that is, the three guide rollers 42 are worn to the same extent. In this regard, the driving mechanism 5 can be used to drive the multiple guide rollers 42 to synchronously approach / move away from the feeding area 22 to adjust the positions of the multiple guide rollers 42 to ensure that the rods can still be accurately guided.

[0033] In addition, the three guide rollers 42 may also be subjected to uneven wear, that is, the three guide rollers 42 may be worn to different amounts. To this end, the fine-tuning assembly 41 may be used to adjust the position of a single guide roller 42 to ensure that the rod can be accurately guided.

[0034] Of course, in actual use, the driving mechanism 5 and the multiple fine-tuning components 41 can be used in combination to flexibly adjust the multiple guide rollers 42.

[0035] Reference Figure 2 and Figure 4 The driving mechanism 5 includes a connecting seat 51 and a connecting ring 52 at the end. The inner hole of the connecting ring 52 is a section of the material flow hole 21. The connecting seat 51 is equipped with a rotatable worm 53. Figure 1 The worm 53 is connected to a knob 54, and the worm 53 can be rotated by turning the knob 54. A rotatable worm wheel 55 is installed on the outer wall of the connecting ring 52 through a bearing. The worm wheel 55 and the worm 53 are meshed and the worm wheel 55 and the worm 53 can be self-locking; the connecting ring 52 is also equipped with a transmission assembly 56, the worm wheel 55 is connected to the transmission assembly 56, and the transmission assembly 56 is connected to multiple fine-tuning assemblies 41.

[0036] Reference Figure 4 and Figure 5 , Figure 5 It is a cross-sectional schematic diagram of the connecting ring 52, and the transmission component 56 includes a linkage ring 561, which is fixedly connected to the worm gear 55 and is coaxially arranged with the worm gear 55, and can rotate together with the worm gear 55, and is connected to the end gear 564, and the linkage ring 561 and the end gear 564 can rotate together; a connecting hole 521 is opened on the connecting ring 52 corresponding to each fine-tuning component 41, and each connecting hole 521 is rotatably connected to a connecting rod 562 through a bearing, and each connecting rod 562 is installed with a linkage gear 563, and the connecting rod 562 and the linkage gear 563 can rotate together, and each linkage gear 563 is meshed with the end gear 564; each connecting rod 562 is connected to the fine-tuning component 41, and the rotation of the connecting rod 562 can drive the fine-tuning component 41 to move back and forth, thereby driving the guide roller 42 to approach or move away from the feeding area 22.

[0037] Turning the knob 54 drives the worm 53 to rotate, thereby driving the worm wheel 55 to rotate. The rotation of the worm wheel 55 will drive the end gear 564 to rotate through the linkage ring 561, thereby driving the three linkage gears 563 to rotate. The rotation of the three linkage gears 563 will drive the three connecting rods 562 to rotate, thereby driving the three fine-tuning components 41 to move and then drive the three guide rollers 42 to move closer to or away from the feeding area 22.

[0038] Reference Figure 6 and Figure 7 The three fine-tuning components 41 have the same structure. Take the structure of the lowest fine-tuning component 41 as an example: the fine-tuning component 41 includes a telescopic connecting arm 411, a connecting ring 52 with a sliding hole 522, and a connecting ring 52 with a sliding hole 522. Figure 5 The sliding hole 522 is a square hole, the telescopic connecting arm 411 is slidably connected to the sliding hole 522, the telescopic connecting arm 411 is provided with a threaded hole 5622, the cross-section of the telescopic connecting arm 411 is square outside and circular inside, the connecting rod 562 has a threaded portion 5621, and the threaded portion 5621 is connected to the threaded hole 5622; the guide roller 42 is rotatably connected to the telescopic connecting arm 411.

[0039] The rotation of the connecting rod 562 drives the telescopic connecting arm 411 to move back and forth, thereby driving the guide roller 42 to move. It should be noted that as long as the guide roller 42 moves a small distance, the adjustment requirement can be met.

[0040] Reference Figure 6 and Figure 7 The telescopic connecting arm 411 includes a sub-arm 4111 slidably connected to the sliding hole 522, a threaded hole 5622 is opened on the sub-arm 4111, a sub-arm 4112 is installed on the sub-arm 4111 and the sub-arm 4112 can slide relative to the sub-arm 4111; a plurality of docking holes 41111 are opened on the sub-arm 4111, and a plurality of docking holes 41121 are opened on the sub-arm 4112, and the docking holes 41111 and the docking holes 41121 are connected to each other with a locking piece, and the locking piece is preferably a detachable pin.

[0041] The lock between sub-arm 1 4111 and sub-arm 2 4112 can be released by removing the locking piece. At this time, the overall length of the telescopic connecting arm 411 can be changed by sliding sub-arm 2 4112 so that the position of a single guide roller 42 can be adjusted. Then, the locking piece can be reinstalled to lock sub-arm 1 4111 and sub-arm 2 4112.

[0042] Reference Figure 8 In order to control the distance of synchronous movement of the three guide rollers, a scale ring 23 is installed on the connection seat 51, and the scale ring 23 is arranged around the knob 54, and the knob 54 has a pointer 24. The user can control the rotation angle of the knob 54 based on the comparison between the pointer 24 and the scale ring 23.

[0043] The implementation principle of a rolling guide in the embodiment of the present application is: Turning the knob 54 drives the worm 53 to rotate, thereby driving the worm wheel 55 to rotate. The rotation of the worm wheel 55 will drive the end gear 564 to rotate through the linkage ring 561, thereby driving the three linkage gears 563 to rotate. The rotation of the three linkage gears 563 will drive the three connecting rods 562 to rotate, thereby driving the three telescopic connecting arms 411 to move back and forth, thereby driving the three guide rollers 42 to synchronously approach or move away from the feeding area 22.

[0044] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
