A steerable guide wheel mechanism

Abstract

This utility model discloses a steerable guide wheel mechanism, including: a base and a steering assembly; the base includes a control box and a fixing ear fixedly installed on its upper end and both sides respectively; the steering assembly includes a movable plate movably installed on the upper end of the base and fixing columns fixedly installed on both sides of the movable plate. In this steerable guide wheel mechanism, the left and right guide discs installed on one side of the main guide wheel and the auxiliary guide wheel on the movable plate can turn with the rotation of the main guide wheel and the auxiliary guide wheel. After turning, the bearings at the inner ends of the left or right guide discs ensure that the wire harness is biased towards the inner end of the left or right guide disc during self-rotation during transport, thereby reducing friction of the wire harness during transport in the inner end of the left or right guide disc during turning, thus avoiding the problem of wire harness friction breakage. Simultaneously, the inner circular opening at one end of the lead wire sleeve can also reduce friction during transport when the wire harness at its inner end is biased to one side through the arc edge.

Description

Technical Field

[0001] This utility model relates to the field of guide wheel technology, specifically a steerable guide wheel mechanism. Background Technology

[0002] In the manufacturing industries of cables, enameled wires, or wire harnesses, guide rollers are used to guide the winding of wire harnesses. Most guide rollers used for winding have a steering adjustment structure to ensure uniform winding during the winding process.

[0003] Existing steerable guide wheel mechanisms, such as the steerable cable guide wheel mechanism disclosed in announcement number CN221116484U, although they can prevent the cable from swaying or rubbing against the cable outlet during the turning process, thus avoiding cable wear or breakage, are not convenient for automatic turning adjustment and cannot guarantee smoothness and ease of turning. Therefore, we propose a steerable guide wheel mechanism. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A steerable guide wheel mechanism includes: a base and a steering assembly; the base includes a control box and a fixed lug fixedly mounted on its upper end and both sides respectively; the steering assembly includes a movable plate movably mounted on the upper end of the base, fixed columns fixedly mounted on both sides of the movable plate, bearings fixedly mounted on both fixed columns, a left guide plate and a right guide plate fixedly mounted on the outer ends of the bearings on both sides respectively, a fixed frame fixedly mounted on the upper end of the movable plate, a main guide wheel and a secondary guide wheel rotatably connected to both sides of the fixed frame, a fixed rod fixedly mounted on one side of the base, and a lead wire sleeve fixedly mounted on the upper end of the fixed rod.

[0007] Preferably, one end of the lead sleeve is also provided with an inner circular opening.

[0008] Preferably, a driven gear is fixedly installed on the upper end of the movable plate, and a driving gear is meshed on the outer end of the driven gear. A groove is also provided on one side of the base, and a reduction motor is fixedly installed in the groove. The upper end of the reduction motor is fixedly connected to the driving gear.

[0009] Preferably, the left guide disk has recesses on both the upper and lower sides, and the right guide disk has protrusions fixedly installed on both the upper and lower sides, with the protrusions matching the recesses.

[0010] Preferably, the bottom of the movable plate is provided with multiple sets of restraint grooves, and each restraint groove is movably installed with ball bearings.

[0011] Preferably, the movable plate and the base are respectively provided with threaded holes and mounting holes, and screws are movably installed in the threaded holes and mounting holes.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] 1. In this utility model, the left and right guide discs installed on one side of the main guide wheel and the auxiliary guide wheel on the movable plate can turn with the main guide wheel and the auxiliary guide wheel. After turning, the bearings at the inner end of the left or right guide disc ensure that the wire harness is biased towards the inner end of the left or right guide disc during the self-rotation of the guide during transportation. This reduces the friction of the wire harness during transportation at the inner end of the left or right guide disc during the turning process, so as to avoid the problem of wire harness friction breakage. At the same time, the inner round opening provided at one end of the lead wire sleeve can also reduce the friction during transportation when the wire harness at its inner end is biased to one side through the arc edge.

[0014] 2. In this utility model, the driven gear driven by the active gear reduction and the ball bearing installed in the binding groove at the bottom of the movable plate can also ensure the smoothness and ease of the movable plate's steering adjustment, and avoid the problem of tearing the wire harness during transportation due to excessive rotation or shaking.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a steerable guide wheel mechanism.

[0025] Example 1:

[0026] Combination Figure 1-5As shown, the present invention provides a steerable guide wheel mechanism, comprising: a base 100 and a steering assembly 200; the base 100 includes a control box 101 and a fixing ear 102 fixedly installed on its upper end and both sides respectively; the steering assembly 200 includes a movable plate 201 movably installed on the upper end of the base 100, fixing columns 202 fixedly installed on both sides of the movable plate 201, bearings 203 fixedly installed on both sides of the fixing columns 202, a left guide plate 204 and a right guide plate 205 fixedly installed on the outer ends of the bearings 203 respectively, a fixing frame 206 fixedly installed on the upper end of the movable plate 201, a main guide wheel 207 and a secondary guide wheel 208 rotatably connected to both sides of the fixing frame 206, a fixing rod 209 fixedly installed on one side of the base 100, and a lead wire sleeve 210 fixedly installed on the upper end of the fixing rod 209, one end of the lead wire sleeve 210 also having an inner... The upper end of the movable plate 201 is fixedly installed with a driven gear 212, and the outer end of the driven gear 212 is also meshed with a driving gear 213. A groove 214 is also opened on one side of the base 100, and a reduction motor 215 is fixedly installed in the groove 214. The upper end of the reduction motor 215 is fixedly connected to the driving gear 213. The upper and lower sides of the left guide plate 204 are also provided with recesses 216. The upper and lower sides of the right guide plate 205 are also fixedly installed with protrusions 217, and the protrusions 217 and recesses 216 are matched. Multiple sets of binding grooves 218 are arranged at the bottom of the movable plate 201, and ball bearings 219 are movably installed in each binding groove 218. Threaded holes 220 and mounting holes 221 are respectively opened in the movable plate 201 and the base 100. Screws 222 are movably installed in the threaded holes 220 and mounting holes 221.

[0027] Specifically, in the production industries of cables, enameled wires, or wire harnesses, guide wheels are used to guide the winding of wire harnesses. Most guide wheels used for winding have a steering adjustment structure to ensure uniform winding. The left guide plate 204 and right guide plate 205 installed on one side of the main guide wheel 207 and auxiliary guide wheel 208 on the movable plate 201 of the base 100 can rotate with the main guide wheel 207 and auxiliary guide wheel 208. After rotation, the bearing 203 at the inner end of the left guide plate 204 or right guide plate 205 ensures... The wire harness is biased towards the inner end of the left guide disk 204 or the right guide disk 205 to guide its self-rotation during transport, thereby reducing the friction of the wire harness during transport in the inner end of the left guide disk 204 or the right guide disk 205 during turning, so as to avoid the problem of wire harness friction breakage. At the same time, the inner circular opening 211 provided at one end of the lead wire sleeve 210 can also reduce the friction during transport when the wire harness at its inner end is biased to one side. In addition, the driven gear 212 driven by the drive gear 213 and the ball bearing 219 installed in the binding groove 218 at the bottom of the movable plate 201 are also included. This also ensures the smoothness and ease of adjustment during the rotation of the movable plate 201, preventing tearing of the conveyed wire harness due to excessive rotation or shaking. The geared motor 215 in the groove 214 mainly drives the drive gear 213, which in turn drives the driven gear 212 and the movable plate 201 to rotate, thereby achieving the rotation of the main guide wheel 207 and the auxiliary guide wheel 208 at the upper end of the movable plate 201. The geared motor 215 maintains an electrical connection with the control box 101. The auxiliary guide wheel 208 installed at the front end of the main guide wheel 207 is mainly used to guide the conveyed wire harness. The wiring harness is guided to the inner end of the main guide wheel 207. The notch 216 and the convex edge 217 that match and connect the left guide plate 204 and the right guide plate 205 are mainly used to ensure a tight connection between the left guide plate 204 and the right guide plate 205, thereby avoiding the problem of the conveyed wiring harness coming off between the left guide plate 204 and the right guide plate 205. The screw 222 installed between the movable plate 201 and the base 100 is mainly used as the central axis in the steering adjustment of the movable plate 201, so as to improve the stability of the movable plate 201 on the upper end of the base 100 during steering.

[0028] Working principle and usage process of this utility model:

[0029] When the geared motor 215 at the upper end of the base 100 drives the drive gear 213, the drive gear 213 will synchronously reduce the speed of the driven gear 212 and the movable plate 201 at the outer end. After the movable plate 201 is smoothly and easily turned by the drive gear 213 at the upper end and the ball bearings 219 and screws 222 at the bottom, the left guide plate 204, right guide plate 205, main guide wheel 207 and auxiliary guide wheel 208 at its upper end will be adjusted synchronously. During the turning of the left guide plate 204 and right guide plate 205, the wire harness in the traction lead sleeve 210 is deflected to one side of the inner round opening 211 at the rear end. The wire harness between the left guide plate 204 and right guide plate 205 will be deflected to the upper end of the left guide plate 204 or right guide plate 205 on the left and right sides according to the turning direction, so as to drive the left guide plate 204 or right guide plate 205 to rotate during the conveying at the upper end of the left guide plate 204 or right guide plate 205, so as to reduce the friction during the conveying of the wire harness.

[0030] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
