Description

Technical Field

[0001] This utility model relates to the field of knurling device technology, and in particular to a track knurling device. Background Technology

[0002] Tracks, typically suspended tracks, are common industrial tools used to transfer or move items or equipment over specific distances. To facilitate the sliding of materials or equipment, tracks are usually made of aluminum alloy. For example, a suspended robot uses an aluminum alloy track, which is suspended in the air, similar to an I-beam structure. The robot is suspended on the track via a suspension mechanism, and its drive wheels abut against the bottom of the track. The rotation of these drive wheels allows the entire robot to move along the track.

[0003] The bottom of the track makes rolling contact with the drive wheel. The outer surface of the drive wheel is made of a material with sufficient friction (such as rubber). Even if the bottom of the track has a common flat structure, there can be enough friction between the drive wheel and the track so that the drive wheel can rotate and drive the robot to move.

[0004] However, by appropriately modifying the structure of the bottom of the track, without changing the overall structure of the robot's drive mechanism (power of the drive motor, preload of the drive mechanism and track, etc.), the friction between the drive wheels and the track can be increased, enabling heavier robots to move on the track or increasing the robot's movement speed on the track.

[0005] However, there is currently no device for knurling the outer bottom of aluminum alloy tracks that have already been installed and suspended. Therefore, it is necessary to provide a track knurling device that can treat the outer bottom of tracks in the above-mentioned situation. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a track knurling device that can knurl the bottom of an installed and suspended aluminum alloy track to increase the roughness of the track's outer bottom, thereby facilitating the movement of the drive wheels of the track-mounted robot.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a track knurling device, comprising a knurling mechanism and a drive mechanism.

[0008] The knurling mechanism includes a mounting base and at least two suspension components and at least one set of knurling cutters mounted on the mounting base.

[0009] Each suspension assembly is used to connect the mounting base and the track, and the drive mechanism cooperates with the mounting base to allow the mounting base to slide along the length of the track;

[0010] Each knurling cutter assembly is connected to the mounting base and makes contact with the bottom outer edge of the track. The movement of the mounting base drives each knurling cutter assembly to perform knurling treatment on the bottom outer edge of the track.

[0011] The principle of this utility model:

[0012] The aluminum alloy track, similar to an I-beam structure, has left and right sides. Therefore, this application provides at least two suspension components to suspend the entire knurling mechanism on the track from both sides. The suspension components can adopt the suspension mechanism structure of the applicant's prior patent application (CN202311830833.6) to ensure that the entire knurling mechanism has a downward gripping force along the track. The drive mechanism can adopt the drive mechanism described in the aforementioned patent, which can drag the mounting base along the track, causing the components mounted on the mounting base to move along the track. Each knurling cutter group connected to the mounting base then has an upward compressing force along the track under the action of the suspension components, allowing each knurling cutter group to perform knurling treatment on the outer bottom of the track as the entire knurling mechanism moves along the track.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The knurling device of this application can knurl the bottom of the installed track to increase the friction of the track and facilitate the subsequent use of the robot.

[0015] Furthermore, there are two sets of knurling cutters, which are spaced apart along the width of the track.

[0016] Furthermore, each knurling cutter assembly includes a connecting post and at least one knurling cutter rotatably connected to the connecting post. The axes of each knurling cutter are arranged side by side along the length of the track, and the connecting post and the mounting base are detachably connected.

[0017] Furthermore, the connection position between the connecting column and the mounting base can be adjusted.

[0018] Furthermore, there are four suspension components, which are arranged in a rectangular pattern on the track and form a hanging space. Each knurling cutter group is located within the hanging space or within the projection of the hanging space.

[0019] Furthermore, the suspension assembly includes a connecting frame and a set of sliding wheels mounted on the connecting frame. The connecting frame and the mounting base are adjustable and fixed, and the set of sliding wheels slides into the track. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] like Figure 1 , 2 As shown, a track knurling device includes a knurling mechanism 200 and a drive mechanism. The knurling mechanism 200 includes a mounting base 210 and at least two suspension components 230 and at least one knurling cutter set 250 disposed on the mounting base 210. Each suspension component 230 is used to connect the mounting base 210 and the track 100. The drive mechanism cooperates with the mounting base 210 to allow the mounting base 210 to slide along the length direction of the track 100. Each knurling cutter set 250 is connected to the mounting base 210 and makes pressing contact with the outer bottom of the track 100. The movement of the mounting base 210 drives each knurling cutter set 250 to perform knurling treatment on the outer bottom of the track 100.

[0027] Understandably, the aluminum alloy track 100 is similar to an I-beam structure, with left and right sides. Therefore, this application provides at least two suspension components 230 to hang the entire knurling mechanism 200 on the track 100 from both sides. The suspension components 230 can adopt the suspension mechanism structure of the applicant's prior patent application (CN202311830833.6) to ensure that the entire knurling mechanism 200 has a downward gripping force along the track 100. The drive mechanism can adopt the drive mechanism described in the aforementioned patent, which can drag the mounting base 210 to move along the length of the track 100, driving the components mounted on the mounting base 210 to move along the track 100. Each knurling cutter group 250 connected to the mounting base 210 has an upward pressing force along the track 100 under the action of the suspension components 230, so that when the entire knurling mechanism 200 moves along the track 100, each knurling cutter group 250 can perform knurling treatment on the outer bottom of the track 100.

[0028] In this application, to ensure a uniform distribution of the clamping force of the knurling mechanism 200 on the track 100, four suspension components 230 are provided. These four suspension components 230 are rectangularly distributed on the track 100, forming a hanging space. Each knurling cutter group 250 is located within or within the projection of the hanging space. The four suspension components 230 effectively apply two downward pressures in the front and rear directions along the length of the track 100, and simultaneously apply two downward pressures on the left and right sides of the track 100. This ensures that the four downward pressures applied by the knurling mechanism 200 on the track 100 are evenly distributed, resulting in smoother and more balanced knurling operation.

[0029] Since the knurling cutter assembly 250 and each suspension assembly 230 clamp the bottom of the track 100 from the bottom and top directions respectively, in order to make the clamping force (preload) adjustable, each suspension assembly 230 of this application includes a connecting frame 231 and a sliding wheel assembly 232 provided on the connecting frame 231. The connecting frame 231 and the mounting base 210 are adjustable and fixed, and the sliding wheel assembly 232 slides in cooperation with the inside of the track 100.

[0030] like Figure 1As shown, the two connecting frames 231 corresponding to the two suspension components 230 located on the same side of the track 100 are combined into a total fixed frame 240. The fixed frame 240 is connected to the mounting base 210 below by multiple connecting bolts 233. By changing the connection depth between the connecting bolts 233 and the mounting base 210, the connection gap width between the fixed frame 240 and the mounting base 210 can be changed. The fixed frame 240 is provided with two sliding wheel groups 232. Each sliding wheel group 232 includes a pressing sliding wheel 2322 for sliding connection with the bottom of the track 100 and an auxiliary sliding wheel 2321 for sliding connection with the inner side wall of the track 100. The axial direction of the pressing sliding wheel 2322 is parallel to the length direction of the track 100. The pressing sliding wheel 2322 cooperates with the track 100 to provide downward pressure for use with the knurling cutter group 250. The axial direction of the auxiliary sliding wheel 2321 is set in a direction perpendicular to the track 100. The auxiliary sliding wheel 2321 can be used to guide the entire knurling mechanism 200 to slide along the track 100.

[0031] To ensure that the knurling cutter set 250 performs knurling on the bottom of the track 100 while rolling, it is necessary to ensure that the knurling cutter set 250 mates with the track 100 at the bottom. The number of knurling cutter sets 250 can be one, multiple sets spaced apart along the length of the track 100, multiple sets arranged along the width of the track 100, or multiple sets arbitrarily placed on the bottom of the track 100.

[0032] Since the track-mounted robot to be coupled on track 100 has two drive wheels, the two drive wheels are arranged side by side along the width direction of track 100 at the bottom of track 100 to fit the left and right sides of track 100. It can be seen that the contact position of the drive wheels is near the left and right sides of the bottom of track 100. Therefore, when performing knurling operation on the bottom of track 100, the corresponding positions of track 100 need to be processed. Therefore, the number of knurling cutter sets 250 in this application is two. The two knurling cutter sets 250 are distributed at intervals along the width direction of track 100, and respectively perform knurling treatment on the left and right sides of the bottom of track 100.

[0033] The knurling cutter assembly 250 can use existing knurling cutters, which can be selected according to the application scenario, such as M0.3, M0.5, 1.0, 1.5, etc. During installation, simply ensure that each knurling cutter assembly 250 is located below the track 100 and has an upward pressing force along the track 100.

[0034] In this application, each knurling cutter assembly 250 includes a connecting post 252 and at least one knurling cutter 251 rotatably connected to the connecting post 252. A knurling cutter assembly 250 with a single knurling cutter 251 is a single-wheel extrusion knurling cutter assembly 250, and a knurling cutter assembly 250 with two knurling cutters 251 is a double-wheel extrusion knurling cutter assembly 250. For example... Figure 4As shown, each knurling cutter group 250 of this application is provided with two knurling cutters 251. The axes of the two knurling cutters 251 are arranged side by side along the length of the track 100. Each knurling cutter 251 is rotatably connected to the upper part of the connecting post 252. The lower part of the connecting post 252 is detachably connected to the mounting base 210.

[0035] like Figure 1 , 2 As shown, the mounting base 210 is provided with two slots 217 for inserting two connecting posts 252. Each slot 217 has multiple locking bolts 215 on its side wall. When connecting, the connecting post 252 is inserted into the corresponding slot 217, and each locking bolt 215 is rotated to lock the connecting post 252 and the slot 217, thus completing the fixed connection between the connecting post 252 and the mounting base 210 and ensuring that the installation position of the hob 251 above the connecting post 252 is adapted.

[0036] Since the lengths of the connecting posts 252 of different models of knurling cutter sets 250 vary, and the knurling cutter set 250 and the suspension assembly 230 can adjust the preload of the knurling mechanism 200 and the track 100 when in use, the connection position of each connecting post 252 and the mounting base 210 in this application is adjustable.

[0037] Specifically, such as Figure 1 , 2 As shown in Figures 3 and 4, each slot 217 has an adjusting bolt 216 at its bottom. By rotating the adjusting bolt 216 and changing the height of the upper end of the adjusting bolt 216 in the slot 217, the upper end of the adjusting bolt 216 contacts the lower part of the connecting post 252, thereby making the depth of the connecting post 252 in the slot 217 adjustable. This also allows for the installation of connecting posts 252 and slots 217 of different lengths.

[0038] Since the knurling mechanism 200 needs to move under the action of the drive mechanism, in order to facilitate the connection between the drive mechanism and the mounting base 210, this application provides connecting buckles 220 at both the front and rear positions of the mounting base 210 along the length direction of the track 100. By connecting with the connecting buckles 220 at different positions, the knurling mechanism 200 can be driven to move at both ends along the length direction of the track 100.

[0039] The mounting base 210 of this application plays a connecting role, requiring the insertion of connecting posts 252 and the connection of fixing brackets 240. Therefore, this application designs the structure of the mounting base 210.

[0040] like Figure 1 , 2As shown in Figures 3 and 4, the mounting base 210 includes a body 211 with a through-slot structure. The body 211 has two sets of opposing sidewalls. At the ends of one set of opposing sidewalls of the body 211, outwardly extending load-bearing plates 212 are respectively provided. Multiple reinforcing structures 214 are provided between the bottom of the load-bearing plate 212 and the outer wall of the body 211. A fixing bracket 240 is located above the corresponding load-bearing plate 212 and connected to it. Corresponding connecting buckles 220 are fixed to the outside of the other set of opposing sidewalls of the body 211. Two columnar structures 213 are connected to the bottom of the body 211. Each columnar structure 213 has a groove, and each groove, together with the through-slot of the body 211, forms a corresponding slot 217 for connecting the insertion of the column 252. Adjusting bolts 216 are threadedly connected to the bottom of each columnar structure 213 and are evenly distributed on the sidewalls of the columnar structures 213, threadedly connected to the columnar structures 213. The mounting base 210 of this application has better support and is also conducive to the installation and replacement of components. This makes the connection between the knurling mechanism 200 and the track 100 more reasonable and the force more balanced, avoiding excessive local preload and ensuring the smooth movement of the knurling mechanism 200 on the track 100.

[0041] The principle of this application:

[0042] Install two pre-set knurling cutter sets 250 on the mounting base 210. The knurling cutter sets 250 are located at the bottom of the track 100 and abut against the outer bottom of the track 100. Then, hang two fixing brackets 240 on the track 100 above the bottom of the track 100. By adjusting the tightness of each connecting bolt 233 on the fixing bracket 240 and the mounting base 210, ensure that the entire knurling mechanism 200 and the track 100 have suitable preload. The connecting buckle 220 on the mounting base 210 is connected to the drive rope / chain, etc. The drive rope / chain is dragged manually or by machine (winding machine, etc.) to achieve the function of the drive mechanism, so as to drive the entire knurling mechanism 200 to move on the track 100 and perform knurling treatment on the outer bottom of the track 100.

[0043] Of course, the drive mechanism can also be the drive mechanism in the applicant's prior patent application (CN202311830833.6), in which the drive mechanism can be mounted on the track 100, and the connecting buckle 220 is directly connected to the first hinge support of the drive mechanism. The drive mechanism can move along the track 100, thereby dragging the knurling mechanism 200 to move along the track 100 to process the outer bottom of the track 100. Alternatively, the drive mechanism can be any other device that can drag the knurling mechanism 200 to move.

[0044] The knurling device of this application can knurl the bottom of the installed track 100, increasing the friction of the track 100 and facilitating the subsequent use of the robot.
