Description

Technical Field

[0001] This utility model relates to the field of lubricating oil level monitoring technology, and more specifically, to an automatic lubricating oil level monitoring device for industrial robots. Background Technology

[0002] An industrial robot is a multi-purpose, reprogrammable, automated control manipulator with three or more programmable axes used in industrial automation. To adapt to different applications, the mechanical interface of the robot's last axis is usually a connecting flange, which can be fitted with different tools or end effectors. A welding robot is a type of industrial robot with a welding clamp or welding gun attached to the flange of its last axis, enabling it to perform welding, cutting, or thermal spraying. The storage capacity in the gearbox of a welding robot directly affects its normal operation.

[0003] Most existing welding robots monitor the lubricating oil level in gearboxes by opening windows on the gearbox for observation. While this method achieves the desired monitoring effect, it is prone to errors when monitored by personnel reading the readings, and requires frequent observation to promptly replenish lubricating oil in gearboxes that are low on lubricating oil. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic lubricating oil level monitoring device for industrial robots. By setting up a monitoring mechanism, the device can replenish oil to the gearbox in a timely manner without the need for the user to frequently observe the oil level, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic lubricating oil level monitoring device for industrial robots, comprising a connecting pipe, a flange plate at the bottom of the connecting pipe, a plurality of bolts at the top of the flange plate, one end of each bolt penetrating the flange plate and extending to the outside of the flange plate, an input pipe on one side of the connecting pipe, one end of the input pipe penetrating the connecting pipe and extending into the connecting pipe, a through hole at the top of the connecting pipe, and a monitoring mechanism disposed inside the through hole.

[0006] In a preferred embodiment, the monitoring mechanism includes a connecting rod, a float is provided at the bottom of the connecting rod, and a connecting plate is provided at the top of the connecting rod.

[0007] In a preferred embodiment, the bottom of the connecting plate is symmetrically provided with fixing plates, one of the fixing plates is provided with an alarm on one side, and both fixing plates are provided with grooves on their tops.

[0008] In a preferred embodiment, a magnet is disposed inside one of the grooves, a protective pad is disposed on top of the magnet, an iron block is disposed on top of the protective pad, and the top of the iron block is connected to the bottom of the connecting plate.

[0009] In a preferred embodiment, a wireless switch is disposed inside another of the grooves, a protective sleeve is disposed on the top of the wireless switch, a connecting block is disposed inside the protective sleeve, and the top of the connecting block is connected to the bottom of the connecting plate.

[0010] In a preferred embodiment, a placement groove is provided on the front side of the connecting plate, and a scale plate is provided inside the placement groove.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] By incorporating a monitoring mechanism, the lubricating oil level in the gearbox can be monitored directly using the monitoring mechanism instead of observing through a window on the gearbox after the gearbox is installed with the device via flange plates and bolts. This monitoring method not only achieves the desired monitoring effect but also minimizes monitoring errors and allows for timely replenishment of lubricating oil to gearboxes with insufficient lubrication without frequent observation. This rational design significantly improves the reliability and safety of gearboxes equipped with this device, thus greatly enhancing the practicality of the device. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As attached Figure 1-4 The device shown is an automatic lubricating oil level monitoring device for industrial robots. It includes a connecting pipe 1 with a flange plate 2 at its bottom. The connecting pipe 1 is placed in a suitable installation position on the gearbox by the flange plate 2. Several bolts 3 are provided on the top of the flange plate 2, with one end of each bolt 3 penetrating the flange plate 2 and extending to the outside of the flange plate 2. The connecting pipe 1 is installed in the corresponding position on the gearbox by the cooperation of the flange plate 2 and the bolts 3. Washers can be added to the bolts 3 to improve stability after use. An inlet pipe 4 is provided on one side of the connecting pipe 1, with one end of the inlet pipe 4 penetrating the connecting pipe 1 and extending into the connecting pipe 1. Lubricating oil is injected through the inlet pipe 4. A cap can be added to the end of the inlet pipe 4 outside the connecting pipe 1 to close the inlet pipe 4. A through hole is opened at the top of the connecting pipe 1, and a monitoring mechanism is installed inside the through hole.

[0020] As attached Figure 1 , 2As shown in Figures 3 and 4, the monitoring mechanism includes a connecting rod 5. A float 6 is installed at the bottom of the connecting rod 5, and a connecting plate 7 is installed at the top of the connecting rod 5. The addition of the float 6 provides a certain buoyancy to the monitoring mechanism, while the addition of the connecting plate 7 limits the downward movement distance of the connecting rod 5. A fixing plate 8 is symmetrically arranged at the bottom of the connecting plate 7. An alarm 9 is installed on one side of one of the fixing plates 8. A groove is opened at the top of both fixing plates 8. The bottom of the fixing plate 8 is connected to the top of the connecting pipe 1. The addition of the alarm 9 will sound an alarm to warn the user when the liquid level is low. A magnet 10 is installed inside one of the grooves. A protective pad 11 is installed on the top of the magnet 10. An iron block 12 is installed on the top of the protective pad 11. The top of the iron block 12 is connected to the bottom of the connecting plate 7. The cooperation between the magnet 10 and the iron block 12 is used to control the float. As the liquid level drops, the iron block 12 enters a groove on the top of one of the fixing plates 8 through the magnetic force of the magnet 10. The addition of a protective pad 11 prevents the iron block 12 from directly contacting the magnet 10 and causing damage to the magnet 10. The protective pad 11 is made of rubber. A wireless switch 13 is installed inside another groove. A protective sleeve 14 is installed on the top of the wireless switch 13. A connecting block 15 is installed inside the protective sleeve 14. The top of the connecting block 15 is connected to the bottom of the connecting plate 7. With the addition of the wireless switch 13 and the connecting block 15, after the magnet 10 contacts the iron block 12, the connecting block 15 simultaneously contacts the wireless switch 13 to turn on the alarm 9. The protective sleeve 14 on the connecting block 15 prevents the connecting block 15 from directly contacting the wireless switch 13 and causing damage to the wireless switch 13.

[0021] As attached Figure 2 , 3 As shown in Figure 4, a placement groove is provided on the front side of the connecting plate 7, and a scale plate 16 is provided inside the placement groove. The addition of the scale plate 16 makes it convenient for users to read the liquid level in the gearbox.

[0022] The working principle of this utility model is as follows: When using this device, first place the connecting pipe 1 on the corresponding installation position of the gearbox through the flange plate 2. After placement, screw multiple bolts 3 into the flange plate 2 in sequence to restrict the position of the connecting pipe 1 and the flange plate 2. After the restriction is completed, the installation of the device is completed. At this time, the monitoring mechanism located in the connecting pipe 1 can monitor the liquid level in the gearbox. When the liquid level in the gearbox drops, the float 6 drives the connecting rod 5 and the connecting plate 7 to move down synchronously. After the connecting plate 7 moves down to the moving position, the iron block 12 and the connecting block 15 at the bottom of the connecting plate 7 respectively enter the groove opened on the top of their corresponding fixing plate 8. When the connecting block 15 enters the groove, it contacts the wireless switch 13, forcing the wireless switch 13 to open the alarm 9 to warn the user that the liquid level in the gearbox is too low. When injecting lubricating oil, it can be injected simply through the injection pipe 4.

[0023] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
