Description

Technical Field

[0001] The invention relates to a double-sided rack guide rail device. Background Art

[0002] Conventional guide rails are only used as guide devices, and conventional gear rack meshing is only used as a transmission device. Combining racks with guide rails to realize transmission and guiding mechanisms with both transmission and guiding functions has been applied in products. This kind of rack guide rail with both transmission and guiding functions generally has gear teeth machined on one side of the guide rail, or the guide rail and the rack are connected together. This rack guide rail with gear teeth on one side can meet the needs of conventional linear guides, circular guides, or closed runway-shaped route guides composed of linear and circular arc segments. However, for curved guide rails with S-shaped turns, the slider running on the guide rail, and its gear meshing with the single-sided gear teeth of the guide rail are sometimes on the inside of the guide rail and sometimes on the outside of the guide rail. This situation is very inconvenient for the slider to turn, increases the precision requirements of the meshing single-sided gear guide rail, and also increases the variety and specifications of the guide rail. Summary of the invention

[0003] The object of the present invention is to provide a double-sided rack guide device, which reduces the difficulty of processing a single rack guide and improves the stability and reliability of the transmission guide. At the same time, it is more convenient for the steering of the guide combination combining straight lines and circular arcs.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A double-sided rack guide rail device comprises a conducting body. Two corresponding toothed belts and two corresponding guide rails are arranged on both sides of the conducting body along the guiding direction.

[0006] Preferably, the conductive body comprises a guide seat and a transmission part, the transmission part is located at the top of the guide seat, the two corresponding guide rails are provided on both sides of the guide seat, and the two corresponding toothed belts are provided on both sides of the transmission part.

[0007] Preferably, the guide seat and the transmission part of the conductive body are integrally formed.

[0008] Preferably, the guide seat and the transmission part transmitted to the main body are connected by screws.

[0009] Preferably, the guide seat of the conductive body includes two guide seat units formed by a combination of two separate parts, and gear teeth are provided on the corresponding outer sides of each guide seat unit; the transmission part includes two transmission part units formed by a combination of two separate parts, and guide rails are provided on the corresponding outer sides of each transmission part unit.

[0010] Preferably, the conductive body comprises a base, and corresponding rack guide rail units are respectively connected to two sides of the base, and gear teeth are provided on one side of the rack guide rail unit, and a guide rail is provided on the other side.

[0011] Preferably, the guide rail device is annular, linear or arc-shaped.

[0012] Preferably, the guide rail device is a curved type formed by combining a straight line type and an arc type.

[0013] The beneficial effects of the present invention are as follows: the double-sided rack guide rail device of the present invention provides gear teeth and guide rails that can drive on both sides, which makes it easier for the slider running on the guide rail to turn in any direction, especially for the curved rack guide rail with an S-shaped bend, which is more conducive to the slider turning in any direction, thereby improving the flexibility of the production line and achieving higher reliability and stability in the transmission of the production line.

[0022] The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of the present invention, so it is necessary to explain them first.

[0023] like Figures 1 to 7As shown, a double-sided rack guide device comprises a conducting body 1, and two corresponding toothed belts and two corresponding guide rails are arranged along the two sides of the conducting body in the guiding movement direction.

[0024] like Figures 1 to 4 As shown, the conducting body 1 is roughly in the shape of an "I", narrow at the top and wide at the bottom, and includes a guide seat 11 and a transmission part 12. The transmission part 12 is located above the guide seat 11, and two corresponding guide rails 111 are provided on both sides of the guide seat 11. The rails are roughly V-shaped, and can also be plane-shaped, cylindrical-shaped or arc-shaped, etc. The two corresponding toothed belts 121 are provided on both sides of the transmission part 12. The transmission part and the two toothed belts provided therewith form a double-sided rack.

[0025] When the slider runs on the guide rail, the V-shaped guide rail is used for guidance, and the gear teeth are used to mesh with the driving gear of the slider running thereon for transmission.

[0026] like Figure 1 As shown, the double-sided rack guide rail device of the present invention can be a linear type, and the guide seat 11 and the transmission part 12 of the conductive body 1 are integrally formed. Figure 6 As shown, the guide seat and the transmission part can also be two independent parts connected by screws 10.

[0027] like Figure 3 As shown, the double-sided rack guide rail device of the present invention can be a circular ring type. Figure 4 As shown, the double-sided rack guide rail device of the present invention can be an arc shape. Figure 5 As shown, the double-sided rack track device of the present invention is a curved type, and the curved type is any combination of a straight line type and an arc type.

[0028] Another embodiment of the present invention is: the guide seat of the conductive body includes two guide seat units formed by a separate assembly, and two guide rails are provided on the corresponding outer sides of each guide seat unit; the transmission part includes two transmission part units formed by a separate assembly, and two gear teeth are provided on the corresponding outer sides of each transmission part unit.

[0029] like Figure 7 and Figure 8 As shown in FIG. 1 , another embodiment of the present invention is shown. The conductive body 1 includes a base 101. Corresponding rack guide rail units 102 are connected to both sides of the base 101. One side of the rack guide rail unit 102 is provided with gear teeth, and the other side is provided with a guide rail. This embodiment is a double-sided rack guide rail composed of two sets of single-sided rack guide rails installed on the base at a certain distance. Figure 7 The gear teeth are on the inside. Figure 8 The gear teeth are on the outside.

[0030] The two sides of the present invention can simultaneously perform gear meshing transmission. Such a transmission guide device reduces the difficulty of processing a single rack guide rail. Since the double-sided rack guide rail has two sets of gear racks that mesh simultaneously to drive the slider to move, this makes the transmission guide of the production line more reliable and stable. At the same time, it is easier to turn the slider device running on the combined guide rail combining straight lines and circular arcs.
