Description

Technical Field

[0001] This utility model relates to the field of leveling automation, and in particular to a high-strength roller connecting key mechanism. Background Technology

[0002] The rotation of the upper and lower rollers of a leveling machine is generally driven synchronously by a transmission box. Referring to application number 202320457720.5, the patent title is: Spline-type universal docking mechanism and leveling machine with such mechanism. The connection between the transmission box and the rollers is achieved through a spline structure. However, spline connection requires manual docking, which is not conducive to the automation of production. In addition, the spline connection structure has weak connection strength and is prone to wear, resulting in a short service life. Utility Model Content

[0003] This utility model provides a high-strength roller connecting key mechanism to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-strength roller connecting key mechanism, comprising a cylindrical outer connecting column with an external fixing hole penetrating its center, a cylindrical inner connecting column with an internal fixing hole penetrating its center, and an elastic buffer assembly. The inner end face of the outer connecting column is uniformly recessed outwards to form several outer slots, and an outer retaining platform is formed between adjacent outer slots. The inner end face of the outer retaining platform is provided with an outer mating end face that slopes from one side wall of the outer retaining platform to the other side wall from the inside out. The outer end face of the inner connecting column is uniformly recessed inwards to form several inner slots, and adjacent inner slots are formed between the inner connecting column and the inner connecting column. An inner locking platform is formed between the two inner locking slots. The outer end face of the inner locking platform forms an inner mating end face parallel to the outer mating end face. The output end of the elastic buffer component elastically abuts against the outer end of the outer connecting post. When the inner connecting post and the outer connecting post are mated, the inner mating end face and the outer mating end face elastically abut against each other, causing the inner connecting post and the outer connecting post to rotate relative to each other. When the inner mating end face and the outer mating end face are separated from each other, the outer locking platform elastically inserts into the corresponding inner locking slot, and the inner locking platform elastically inserts into the corresponding outer locking slot, thereby causing the outer connecting post and the inner connecting post to rotate and lock together.

[0005] Preferably, the elastic buffer assembly includes a spring base with an internally and externally penetrating axial fixing hole in the center, a plurality of spring sleeves, and a plurality of springs. The inner end face of the spring base has a plurality of internally and externally oriented spring slots evenly distributed outside the axial fixing hole. The bottom wall of each spring slot has a sleeve through-hole penetrating the outer end face of the spring base. The outer end of the outer connecting post has a plurality of sleeve fixing holes. Each spring sleeve includes a cap, a spring sleeve integrally fixed to the inner end of the cap, and a spring sleeve integrally fixed to the... The spring sleeve has an inner fixed insertion portion that passes through the pin through hole and the spring slot hole. The fixed insertion portion is fixedly inserted into the pin fixed insertion hole. The diameter of the pin head and the diameter of the spring slot hole are both larger than the diameter of the pin through hole. The length of the spring sleeve is greater than the depth of the spring slot hole. The spring is sleeved outside the spring sleeve and installed inside the spring slot hole. The outer end of the spring abuts against the bottom wall of the spring slot hole, and the inner end of the spring abuts against the outer end face of the outer connecting post.

[0006] Preferably, there are four inner card slots and four inner card receiving platforms, and correspondingly, there are also four outer card slots and four outer card receiving platforms.

[0007] Preferably, the outer side wall of the inner connecting column is provided with an inner locking screw hole that communicates with the inner fixing insertion hole, and the outer side wall of the spring base is provided with an outer locking screw hole that communicates with the axial fixing insertion hole.

[0008] Compared with the prior art, when the outer connecting column and the inner connecting column are connected, there is no need for direct and precise docking and insertion. It is only necessary to rotate the outer connecting column and the inner connecting column relative to each other. When the inner docking end face and the outer docking end face are separated from each other, a mutual rotational locking can be achieved. This connection method can be implemented automatically, making it more flexible and convenient to use. In addition, the docking of the outer connecting column and the inner connecting column is achieved by the outer locking platform elastically inserting into the corresponding inner locking groove, and the inner locking platform elastically inserting into the corresponding outer locking groove. The locking is achieved by the locking groove and the locking platform, resulting in stronger locking and a more secure and tighter connection. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Please see Figures 1-5 The high-strength roller connecting key mechanism of this utility model includes an outer connecting post 10 that is cylindrical and has an outer fixing insertion hole 11 that penetrates through it internally and externally, an inner connecting post 20 that is cylindrical and has an inner fixing insertion hole 21 that penetrates through it internally and externally, and an elastic buffer component 30.

[0012] The inner end face of the outer connecting post 10 is uniformly recessed outward to form a plurality of outer slots 12. An outer contact platform 13 is formed between two adjacent outer slots 12. The inner end face of the outer contact platform 13 is provided with an outer contact end face 131 that slopes from one side wall of the outer contact platform 13 to the other side wall of the outer contact platform 13 from the inside out. The outer end face of the inner connecting post 20 is uniformly recessed inward to form a plurality of inner slots 22. An inner contact platform 23 is formed between two adjacent inner slots 22. The outer end face of the inner contact platform 23 forms an inner contact end face 231 that is parallel to the outer contact end face 131. The output end of the elastic buffer assembly 30 elastically abuts against the outer end of the outer connecting post 10. When the inner connecting post 20 mates with the outer connecting post 10, the inner mating end face 231 and the outer mating end face 131 elastically abut against each other, causing the inner connecting post 20 and the outer connecting post 10 to rotate relative to each other. When the inner mating end face 231 and the outer mating end face 131 disengage, the outer locking platform 13 elastically inserts into the corresponding inner locking groove 22, and the inner locking platform 23 elastically inserts into the corresponding outer locking groove 12, thereby causing the outer connecting post 10 and the inner connecting post 20 to rotate and lock together. The outer side wall of the inner connecting post 20 is provided with an inner locking screw hole 24 that communicates with the inner fixing insertion hole 21. In this embodiment, there are four inner locking grooves 22 and four inner locking platforms 23, and correspondingly, there are also four outer locking grooves 12 and four outer locking platforms 13. The planes containing both sides of the inner locking platform 23 pass through the central axis of the inner locking post 20, and the planes containing both sides of the outer locking platform 13 pass through the central axis of the outer locking post 10.

[0013] Specifically, the elastic buffer assembly 30 includes a spring base 31 with an internally and externally penetrating axial insertion hole 311 in the center, a plurality of spring sleeve pins 32, and a plurality of springs 33. The inner end face of the spring base 31 has a plurality of internally and externally oriented spring slots 312 evenly distributed outside the axial insertion hole 311. The bottom wall of the spring slot 312 has a sleeve pin through hole 313 penetrating the outer end face of the spring base 31. The outer end of the outer connecting post 10 has a plurality of sleeve pin insertion holes 15. The spring sleeve pin 32 includes a pin head 321, a spring sleeve post 322 integrally fixed to the inner end of the pin head 321, and a spring sleeve post integrally fixed to the spring sleeve post. The inner end of the spring base 322 has a fixed insertion portion 323. The spring sleeve 322 passes through the pin through hole 313 and the spring slot 312. The fixed insertion portion 323 is fixedly inserted into the pin fixed insertion hole 15. The diameter of the pin head 321 and the diameter of the spring slot 312 are both larger than the diameter of the pin through hole 313. The length of the spring sleeve 322 is greater than the depth of the spring slot 312. The spring 33 is sleeved outside the spring sleeve 322 and installed inside the spring slot 312. The outer end of the spring 33 abuts against the bottom wall of the spring slot 312, and the inner end of the spring 33 abuts against the outer end face of the outer connecting post 10. The outer side wall of the spring base 31 has an external locking screw hole 314 that communicates with the shaft fixed insertion hole 311. In this embodiment, the fixed insertion portion 323 is a screw, and the pin fixed insertion hole 15 is a screw hole.

[0014] In use, the output shaft 210 of the output gear 200 of the transmission box is fixedly inserted into the shaft fixing insertion hole 311. A locking screw is screwed into the outer locking screw hole 14, thereby locking the spring base 31 and the output shaft 210 together. The rotating shaft 310 at the end of the roller 300 passes through the rotating mounting hole 410 of the mounting bracket 400 and is fixedly inserted into the inner fixing insertion hole 21. A locking screw is screwed into the inner locking screw hole 24, thereby locking the inner connecting post 20 and the rotating shaft 310 together. The outer connecting post 10 and the inner connecting post 20 are mated together. When the outer connecting post 10 elastically compresses the spring 33, the inner mating end face 231 and the outer mating end face 131 elastically abut against each other, causing the inner connecting post 20 and the outer connecting post 10 to rotate relative to each other. When the inner mating end face 231 and the outer mating end face 131 disengage from each other, the outer locking platform 13 elastically inserts into the corresponding inner locking groove 22, and the inner locking platform 23 elastically inserts into the corresponding outer locking groove 12, thereby causing the outer connecting post 10 and the inner connecting post 20 to rotate and lock together. When the outer connecting post 10 is connected to the inner connecting post 20, there is no need for direct and precise docking and insertion. Simply rotate the outer connecting post 10 and the inner connecting post 20 relative to each other. When the inner docking end face 231 and the outer docking end face 131 disengage from each other, a mutual rotational locking mechanism can be achieved. This connection method can be implemented automatically, making it more flexible and convenient to use. In addition, the docking of the outer connecting post 10 and the inner connecting post 20 is achieved by the outer locking platform 13 being elastically inserted into the corresponding inner locking groove 22, and the inner locking platform 23 being elastically inserted into the corresponding outer locking groove 12. The locking mechanism of the groove and the locking platform achieves a rotational locking mechanism, resulting in stronger locking strength and a more secure and tight connection.

[0015] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
