Technical Field

[0001] The utility model relates to the technical field of mechanical transmission, in particular to a translation mechanism. Background Art

[0002] Mechanical transmission refers to the method of transferring an object to another place by mechanical means. There are many ways of mechanical transmission, among which the most common one is translation transmission.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0033] Embodiment 1:

[0034] A translation mechanism includes a guide rail 1 and a slider 2. The slider 2 is slidably connected to the inside of the guide rail 1. The top and bottom of the slider 2 are fixedly connected to steel bars 3. The inside of the guide rail 1 is fixedly installed with a roller 4 used in conjunction with the steel bar 3. A driving device 5 is fixedly installed on one side of the guide rail 1. A transmission gear 6 is fixedly installed on the output end of the driving device 5. The bottom of the transmission gear 6 is meshed with a tooth plate 7. One side of the tooth plate 7 is fixedly connected to one side of the slider 2. A plurality of storage racks 8 are arranged on one side of the slider 2.

[0035] In this embodiment, it is considered that there are many types of existing mechanical transmission methods, but most of them have a problem. The object is heavy and is prone to shaking during the transmission process, causing the object to fall, affecting the transmission efficiency. Therefore, by setting a translation mechanism, when the driving device 5 drives the gear to rotate, the gear will drive the toothed plate 7 to move, and the toothed plate 7 will drive the slider 2 to slide inside the guide rail 1, and at the same time drive the triangular support frame 11 and the storage rack 8 to move, and transmit the objects on the storage rack 8. In the process, the guide rail 1 itself will limit the movement trajectory of the slider 2, and the roller 4 and the steel bar 3 will also limit the movement trajectory, so that the movement mode of the slider 2 is changed from sliding to rolling, thereby effectively improving the stability during the transmission process, and then achieving the effect of improving the transmission efficiency;

[0036] The problem that there are many types of existing mechanical transmission methods, but most of them have a problem, that is, the objects are heavy and are prone to shaking during the transmission process, causing the objects to fall and affecting the transmission efficiency;

[0037] It should be noted that the driving device 5 is a servo motor, which has strong power and can rotate in both directions to control the slider 2 to move left and right.

[0038] Preferably, the slider 2 and the steel bar 3 are formed into one piece by die casting.

[0039] In this embodiment, the slider 2 and the steel bar 3 are pre-die-casted to form an integral whole, which can save processing costs and reduce manual operation time. At the same time, the die-casting method can make the two fit perfectly, thereby improving the accuracy of the fit.

[0040] Preferably, the steel bar 3 is cylindrical in shape and fits tightly against the inner wall of the roller 4 .

[0041] In this embodiment, by setting the steel bar 3 to be cylindrical, the surface of the steel bar 3 exposed on the outside of the slider 2 can be closely fitted with the inner wall of the roller 4, thereby improving the accuracy of the fit between the two, thereby achieving the effect of improving the stability during the transmission process.

[0042] Preferably, a triangular support frame 11 is fixedly installed at the bottom of the storage rack 8 , and one side of the triangular support frame 11 is fixedly connected to one side of the slider 2 .

[0043] In this embodiment, by providing the triangular support frame 11, the stability of the rack 8 can be improved. When the items are placed on the rack 8, the rack 8 will not shake, thereby improving the stability during the transportation process.

[0044] Preferably, the driving device 5 is a servo motor.

[0045] In this embodiment, the driving device 5 is selected as a servo motor, which has a strong power output and can also have high stability during the emergency stop process. In comparison, it is more suitable for safe and stable transmission.

[0046] Embodiment 2:

[0047] On the basis of the first embodiment, the translation mechanism in this embodiment can improve the stability by changing the sliding mode of the slider 2 to rolling mode, but considering that the spacing between the rollers 4 is too large, it will also affect the transmission effect, and setting too many rollers 4 will cause waste of materials. In this application, the number of rollers 4 is several, and screws 9 are set on one side of the roller 4, and the roller 4 is fixed to the inner wall of the guide rail 1 by the screws 9.

[0048] Preferably, the inner wall of the guide rail 1 is provided with a plurality of threaded holes 10 for use with the screws 9, and the spacing between the rollers 4 can be adjusted by cooperating between the screws 9 and different threaded holes 10.

[0049] In this embodiment, it is taken into consideration that too large a spacing between the rollers 4 will also affect the transmission effect, and setting too many rollers 4 will cause waste of materials. Therefore, by setting screws 9 and threaded holes 10, the spacing between the rollers 4 can be adjusted by disassembling the rollers 4, and the number of rollers 4 can also be appropriately increased or decreased to make the number of rollers 4 the most preferred, thereby avoiding waste of materials and improving stability during the transmission process.

[0050] Working principle: When the driving device 5 drives the gear to rotate, the gear will drive the tooth plate 7 to move, and the tooth plate 7 will drive the slider 2 to slide inside the guide rail 1, and at the same time drive the triangular support frame 11 and the storage rack 8 to move, and transmit the items on the storage rack 8. In the process, the guide rail 1 itself will limit the movement trajectory of the slider 2. At the same time, the roller 4 and the steel bar 3 will also limit the movement trajectory, so that the movement mode of the slider 2 is changed from sliding to rolling, thereby effectively improving the stability during the transmission process, thereby achieving the effect of improving the transmission efficiency.

[0051] It should be noted that the drive device 5 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art, and the specific composition and principle of the power supply of the drive device 5 are clear to those skilled in the art, so they are not described in detail.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
