Description

Technical Field

[0001] The utility model relates to an arc-shaped guide rail, in particular to an arc-shaped guide rail driven by a gear rack. Background Art

[0002] In the process of automated material transportation and processing, closed-loop annular guide rails are generally used. The carrier plate used to place the material can make circular motion along the annular guide rail under the drive of the motor. However, in non-standard automated processing equipment, it is often necessary to embed a processing mechanism in the closed-loop annular guide rail, that is, the closed-loop annular guide rail needs to be interrupted. At present, there are also such guide rails on the market, but this guide rail is basically a straight line. For the processing of some special products, it is often necessary to use curved rails and linear guide rails to guide and transmit the carrier plate. The advantage of the curved rail is that it can smoothly transition between two sections of linear guide rails, which is convenient for the carrier plate to make reciprocating motion. However, the limiting structure is easy to get stuck on the curved rail, resulting in uneven movement of the carrier plate. In response to this problem, the inventor designed an arc guide rail driven by a gear rack. Utility Model Content

[0003] The purpose of the utility model is to provide an arc-shaped guide rail driven by a gear rack, which has a simple structure, a reasonable design, can be embedded in various processing mechanisms for use, and the load-bearing plate can slide smoothly on the curved rail and the straight rail, and has the advantages of good stability, thereby solving the problems raised by the above technical background.

[0027] See also Figures 1 to 3The present invention provides an embodiment of a gear rack driven arc guide rail, the arc guide rail comprising:

[0028] The guide rail body 1 is provided with two guide rail bodies 1. The two guide rail bodies 1 are arranged at intervals. The two guide rail bodies 1 are provided to make the arc guide rail more stable and meet the load-bearing requirements of different products. The guide rail body 1 includes a curved rail 11 and straight rails 12 arranged at both ends of the curved rail 11. Both sides of the curved rail 11 and the straight rail 12 are provided with limiting slide grooves 13. The limiting slide grooves 13 are distributed along the length direction of the curved rail 11 and the straight rail 12. In a specific implementation, the cross section of the limiting slide groove 13 is U-shaped;

[0029] The rack body 2 is arranged on one side of the guide rail body 1. The rack body 2 includes a curved tooth 21 and straight teeth 22 arranged at both ends of the curved tooth 21. The straight teeth 22 are arranged parallel to the straight rail 12.

[0030] The carrying plate 3 is located above the guide rail body 1 and the rack body 2 and is used to place products. In order to facilitate the installation of a jig for carrying items (not shown in the figure), a mounting hole 31 is opened on the carrying plate 3;

[0031] The limiting structure 4 is arranged at the bottom of the bearing plate 3 and is limitedly connected to the guide rail body 1. The limiting structure 4 includes two groups of limiting wheels 41 that can slide along the limiting groove 13. Each of the limiting wheels 41 is rotatably mounted on the limiting shaft 42, and the limiting wheel 41 can rotate along the radial direction of the limiting shaft 42. The limiting shaft 42 is connected to the bearing plate 3 at one end away from the limiting wheel 41, and a bearing step 44 for bearing the gravity of the bearing plate 3 is provided on the limiting shaft 42 along its circumferential direction. When the bearing plate 3 moves to the curved rail 11, the limiting wheels 41 on the inner side of the curved rail 11 abut against the curved rail 11. This can increase the friction between the limiting wheel 41 and the curved rail 11, which can achieve the purpose of deceleration, and at the same time can also meet the needs of the carrying plate 3 slowly passing through the curved rail 11, ensuring that the carrying plate 3 slides smoothly on the curved rail 11, and improving its stability. The limiting wheel 41 is a centering roller, and the limiting wheel 41 is provided with a slope surface 43 adapted to the limiting slide groove 13, which can reduce the contact area between the limiting wheel 41 and the limiting slide groove 13, thereby reducing friction and ensuring that the carrying plate 3 runs quickly and stably. The centering roller has the effects of high precision, good stability, high speed, and is not easy to loosen, and its use in this embodiment has a better effect;

[0032] The driving structure 5 includes a motor 51 fixedly mounted on the carrier plate 3. The output end of the motor 51 passes through the carrier plate 3 from top to bottom and is connected to the gear body 52. ​​The gear body 52 is engaged with the rack body 2. When the motor 51 drives the gear body 52 to rotate, the carrier plate 3 can move back and forth along the length direction of the rack body 2. In this way, the arc guide rail in the utility model can be embedded in the processing mechanism of various equipment for use, which is highly practical.

[0033] The arc guide rail in the present invention also includes a base plate 6, which is used to install the guide rail body 1 and the rack body 2. The guide rail body 1 and the rack body 2 can be detachably installed on the base plate 6, specifically by using detachable screws to facilitate replacement of the guide rail body 1 and the rack body 2 that are prone to wear.

[0034] In this embodiment, it should be noted that the motor 51 is a servo motor, which has high precision and good working stability and can control the carrier plate 3 to stop at any position of the guide rail body 1 to meet different user requirements.
