Description

Technical Field

[0001] This utility model belongs to the field of profile processing technology, and in particular relates to a novel dual encoder structure. Background Technology

[0002] Encoder feedback feeding is a commonly used feeding method in profile processing. Compared with gear and rack or lead screw and nut feeding methods, encoder feedback feeding has a simple structure, is easy to use, and is inexpensive.

[0003] Currently available encoders have the following problems when used:

[0004] 1. In practical use, traditional encoders usually have a metering wheel structure installed inside the encoder. During use, slippage with the material is inevitable, which leads to inaccurate encoder feedback data. Therefore, the impact of slippage cannot be avoided during use.

[0005] 2. In practical applications, most encoders are installed on top of the support structure. Once external force is transmitted to the encoder, it can easily cause the shaft to bend or the bearings inside the encoder to be damaged. Therefore, it can cause unexpected damage to the encoder during application. Utility Model Content

[0006] The purpose of this invention is to provide a novel dual encoder structure to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A novel dual encoder structure includes a base, an outer slider is slidably installed inside the base, two holes are opened inside the outer slider, and an inner slider is slidably installed inside the holes respectively. An encoder structure assembly is provided on one side of each inner slider.

[0008] Preferably, a rear plate is mounted on one side of the outer slider, and a spring is provided between the inner slider and the rear plate.

[0009] Preferably, the inner slider has a waist-shaped hole inside, and the outer slider has a pin hole inside, with a pin installed in the pin hole.

[0010] Preferably, the encoder includes an upper bracket on which the encoder is mounted, and a lower bracket on one side of the upper bracket. The upper bracket and the lower bracket are mounted on one end of the inner slider. A bearing is installed inside the lower bracket, and a metering wheel is installed inside the bearing. A connecting pin is fixedly connected to the inner hole of the metering wheel. A coupling is installed between the connecting pin and the encoder and the input shaft.

[0011] Preferably, the lower support includes a support rear plate, and a support front plate is installed on one side of the support rear plate.

[0012] Preferably, a rod is installed on one side of the base, and the rod is connected to the inner slider by an elastic traction member.

[0013] Preferably, the upper support includes a horizontal plate A, a horizontal plate B, and a vertical plate, wherein the horizontal plate A, the horizontal plate B, and the vertical plate are welded together.

[0014] The novel dual encoder structure of this utility model has the following advantages:

[0015] 1. This novel dual encoder structure avoids slippage by installing an inner slider, an outer slider, and an encoder assembly inside the base. The outer slider is installed inside the base, and the inner slider is installed inside the outer slider. The encoder assembly is installed outside both the inner and outer sliders. This dual encoder system, combined with a PLC program, detects slipping encoders and effectively filters out slipping data. Data from the non-slipping encoders is then used to obtain accurate encoder feedback data, thus avoiding the impact of slippage during use.

[0016] 2. This novel dual encoder structure, by installing an upper bracket, lower bracket, measuring wheel, connecting pin, and coupling on the outside of the encoder, avoids damage to the encoder. It uses two brackets: one to mount the encoder and the other to mount the measuring wheel. The measuring wheel is connected to the lower bracket via bearings and then to the encoder input shaft via a coupling. The material only contacts the measuring wheel, preventing unexpected forces, such as lateral forces, from being transmitted to the encoder input shaft. Rotational forces are transmitted to the input shaft via the coupling, thus avoiding bending of the encoder shaft or damage to the internal bearings caused by external forces, especially lateral forces. The main force is borne by the lower bracket and its bearings, preventing accidental damage to the encoder during application. Attached Figure Description

[0028] To better understand the purpose, structure, and function of this utility model, the following detailed description of a novel dual encoder structure is provided in conjunction with the accompanying drawings.

[0029] like Figure 1-4 As shown, this utility model discloses a novel dual encoder structure, including a base 9. The base 9 facilitates the installation of an outer slider 10 and an inner slider 6 inside. The outer slider 10 is slidably installed inside the base 9. Two holes are opened inside the outer slider 10, and the inner slider 6 is slidably installed inside each hole. An encoder 1 assembly is provided on one side of each inner slider 6. By installing the inner slider 6, outer slider 10, and encoder 1 inside the base 9, two encoder 1 systems are used. Combined with a PLC program to detect slipping encoder 1 data, slipping data can be effectively filtered out, avoiding the impact of slippage during use.

[0030] A back plate 8 is installed on one side of the outer slider 10, and a spring 7 is provided between the inner slider 6 and the back plate 8. The presence of the spring 7 facilitates the connection between the inner slider 6 and the back plate 8.

[0031] The inner slider 6 has a waist-shaped hole 17 inside, and the outer slider 10 has a pin hole 18 inside. A pin is installed in the pin hole 18. Because the pin hole 18 is provided, it is convenient to install the pin inside the pin hole 18.

[0032] The encoder 1 includes an upper bracket 2, on which the encoder 1 is mounted. A lower bracket 5 is mounted on one side of the upper bracket 2. The upper bracket 2 and the lower bracket 5 are mounted on one end of an inner slider 6. A bearing 4 is installed inside the lower bracket 5, and a measuring wheel 14 is installed inside the bearing 4. A connecting pin 11 is fixedly connected to the inner hole of the measuring wheel 14. A coupling 3 is installed between the connecting pin 11 and the input shaft 19 of the encoder 1. By installing the upper bracket 2, the lower bracket 5, the measuring wheel 14, the connecting pin 11, and the coupling 3 on the outside of the encoder 1, the encoder 1 is mounted on one bracket, and the measuring wheel 14 is mounted on the other bracket. The measuring wheel 14 is connected to the lower bracket 5 through the bearing 4, and then connected to the encoder 1 and the input shaft 19 through the coupling 3. The material is always only in contact with the measuring wheel 14. Accidental forces, mainly the forces, are borne by the lower bracket 5 and the bearing 4 therein. Therefore, accidental damage to the encoder will not occur during application.

[0033] The lower bracket 5 includes a bracket rear plate 13, and a bracket front plate 12 is installed on one side of the bracket rear plate 13. Because of the bracket rear plate 13 and the bracket front plate 12, it is convenient to install the lower bracket 5 on the outside of the bearing 4.

[0034] A rod 15 is installed on one side of the base 9. The rod 15 is connected to the inner slider 6 by an elastic traction member 16. Because an elastic traction member is provided, it is convenient to connect the rod 15 to the inner slider 6.

[0035] The upper support 2 includes a horizontal plate A21, a horizontal plate B23, and a vertical plate 22. The horizontal plate A21, the horizontal plate B23, and the vertical plate 22 are welded together. The vertical plate 22 facilitates the connection and fixation of the flat plate A, the horizontal plate B23, and the vertical plate 22 by welding.

[0036] The working principle of this new dual encoder structure is as follows: When using encoder 1, the dual encoder 1 first needs to be moved to the designated position. After moving to the designated position, it is then installed using fasteners. To avoid accidental damage to the encoder, two sets of encoders 1 are installed. This is achieved by installing an upper bracket 2, a lower bracket 5, a metering wheel 14, a connecting pin 11, and a coupling 3 on the outside of encoder 1. Two brackets are used simultaneously; one bracket mounts the encoder 1, and the other mounts the metering wheel 14. The metering wheel 14 is then connected to the lower bracket 5 via a bearing 4, and finally connected to the input shaft 19 on the outside of encoder 1 via coupling 3. This ensures that the material only contacts the metering wheel 14, avoiding contact with unexpected forces. Lateral forces are not transmitted to the input shaft 19 of encoder 1. The rotational force is transmitted to the input shaft 19 via coupling 3, thus preventing external forces, especially lateral forces, from driving the input shaft 19 of encoder 1. The upper part of the encoder 1 may cause bending of the shaft or damage to the bearing 4 inside the encoder 1. The main force is borne by the lower bracket 5 and the bearing 4 therein, so it will not cause accidental damage to the encoder during application. Secondly, in order to avoid slippage, the inner slider 6, outer slider 10 and encoder 1 assembly are installed inside the base 9. The outer slider 10 is installed inside the base 9, and the inner slider 6 is installed inside the outer slider 10. The inner slider 6 has a waist-shaped hole inside, and the pin hole 18 is opened on the outside of the outer slider 10. At the same time, the encoder 1 assembly is installed on the outside of the inner slider 6 and the outer slider 10. In this way, two sets of encoder 1 systems are used. Then, the PLC program is used to detect the slipping encoder 1. This can effectively filter out the slipping data. Then, the data of the non-slipping encoder 1 is used to obtain accurate encoder 1 feedback data. Therefore, the influence caused by slippage can be avoided during use.
