Technical Field

[0001] This utility model belongs to the field of laser cutting technology, specifically, it relates to a transmission lubrication device for a laser cutting machine. Background Technology

[0002] The transmission mechanism of a laser cutting machine is a core component ensuring precise cutting and efficient operation. During operation, all moving parts require continuous lubrication to reduce friction loss and prevent component wear and jamming. Existing laser cutting machine transmission lubrication systems mostly use a single oil supply line, lacking a targeted diversion and uniform distribution structure. This results in insufficient lubrication of all parts, leading to inadequate lubrication of some critical moving parts. Furthermore, impurities in the lubricating oil can easily clog oil lines or scratch the surfaces of transmission components. Traditional devices lack effective filtration and maintenance structures, requiring frequent disassembly and cleaning of the entire unit. This not only affects the normal operating efficiency of the equipment but also increases maintenance costs and operational difficulty, severely restricting the long-term stable use of the laser cutting machine.

The oil outlet connector is connected to the oil distributor in sequence via a connector one, an oil supply pipe one, a connector two, and a right-angle connector. The tee is connected in series between the oil supply pipe one and the connector one, dividing the lubrication oil path into two paths. One side of the oil distributor is connected to the lubrication felt wheel via a sealing connector and a lubrication pipe one, and the other side is connected to the slider via a lubrication pipe two and a quick-connect connector.

[0021] like Figures 1 to 3 As shown, a transmission lubrication device for a laser cutting machine includes a lubrication pump 1, an oil inlet 2, a tee 4, an oil distributor 9, a lubrication felt wheel 13, and a slider 16.

The tee 4 is connected in series between the oil supply pipe 5 and the connector 3, dividing the lubrication oil path into two paths. One side of the oil distributor 9 is connected to the lubrication felt wheel 13 through a sealing connector 11 and a lubrication pipe 12, and the other side is connected to the slider 16 through a lubrication pipe 14 and a quick-connect connector 15. A limit switch is installed on the slider 16.

[0022] The oil inlet nozzle 2 includes an oil inlet pipe 204, a filter pipe 203, and a connecting pipe 202. The filter pipe 203 has a filter element inside and a leakage hole 205 on its wall. The oil inlet pipe 204 is connected to the oil inlet connector 101 through the filter pipe 203 and the connecting pipe 202. The oil inlet nozzle 2 has a cleaning port 201 with a removable sealing cap. The filter pipe 203, the oil inlet pipe 204, and the connecting pipe 202 are all detachably connected.

[0023] A pressure switch 8 is installed between the right-angle connector 7 and the oil distributor 9 to monitor the oil circuit pressure. A grease metering element 10 is installed between the oil distributor 9 and the sealing connector 11 to measure the amount of lubricating oil delivered. One end of the lubrication pipe 12 extends into the interior of the lubrication felt wheel 13, and the other end is fixedly connected to the sealing connector 11. The lubrication felt wheel 13 is rotatable to evenly distribute the lubricating oil. The two lubrication circuits separated by the tee 4 have the same structure and are both equipped with an oil distributor 9, a lubrication felt wheel 13, and a slider 16.

[0024] The oil inlet connector 101 is fixedly installed at the oil inlet end of the lubrication pump 1, and the oil outlet connector 102 is fixedly installed at the oil outlet end. The oil inlet connector 101 is sealed and connected to the oil inlet nozzle 2 through a pipeline to realize the introduction of lubricating oil.

[0025] The oil inlet nozzle 2 consists of an oil inlet pipe 204, a filter pipe 203, and a connecting pipe 202, which are connected by a detachable threaded connection. A columnar filter element is embedded inside the filter pipe 203, and several leakage holes 205 are evenly opened around the pipe wall. The oil outlet end of the oil inlet pipe 204 is inserted into one end of the filter pipe 203, and the other end of the filter pipe 203 is connected to the connecting pipe 202. The end of the connecting pipe 202 away from the filter pipe 203 is connected to the oil inlet connector 101. A cleaning port 201 is opened on the side wall of the oil inlet nozzle 2, and a detachable sealing cap is threaded to the cleaning port 201 to facilitate regular cleaning of filter element impurities.

[0026] The oil outlet connector 102 of the lubrication pump 1 is fixed to the connector 3 by threads. The end of the connector 3 away from the oil outlet connector 102 is sealed to the main interface of the tee 4. The two branch interfaces of the tee 4 are respectively connected to two oil supply pipes 5 with the same structure to realize the diversion of lubricating oil circuit.

[0027] The end of each oil supply pipe 5 furthest from the tee 4 is threaded to the connector 6. The connector 6 is fixed to one end of the right-angle connector 7. The other end of the right-angle connector 7 is connected to the input end of the pressure switch 8 through a flange. The output end of the pressure switch 8 is sealed to the input end of the oil distributor 9 for real-time monitoring of oil circuit pressure and feedback of abnormal signals.

[0028] The two output ports of the oil distributor 9 correspond to two oil supply branches: one branch is connected to the sealing joint 11 through the grease metering element 10. The grease metering element 10 adopts a gear-type metering structure to accurately count the amount of lubricating oil delivered. The end of the sealing joint 11 away from the oil distributor 9 is fixed to the lubrication pipe 12. The free end of the lubrication pipe 12 extends into the shaft of the lubrication felt wheel 13 and is sealed to the rotating shaft of the lubrication felt wheel 13. The lubrication felt wheel 13 is rotatably mounted on the part to be lubricated in the transmission mechanism of the laser cutting machine through a bracket. The other output port of the oil distributor 9 is connected to the lubrication pipe 14. The lubrication pipe 14 is detachably connected to the oil inlet of the slider 16 through the quick-connect connector 15. The slider 16 is slidably mounted on the side of the transmission mechanism through the guide rail. It has a lubricating oil diversion channel inside. A limit switch is fixedly mounted on the side wall of the slider 16. The limit switch is electrically connected to the drive component of the slider 16.

[0029] Workflow

[0030] When the laser cutting machine is started and the transmission mechanism requires lubrication, the device operates as follows:

[0031] Lubricating oil is injected from the oil inlet pipe 204 of the oil inlet 2, flows through the oil inlet pipe 204 and enters the filter pipe 203. Impurities are intercepted by the filter element inside the filter pipe 203, and the oil permeates through the leakage hole 205 into the gap between the filter pipe 203 and the connecting pipe 202. Then it is transported to the oil inlet connector 101 through the connecting pipe 202 and finally enters the lubrication pump 1.

[0032] After the lubrication pump 1 starts, it pressurizes the lubricating oil. The pressurized lubricating oil is output from the oil outlet connector 102, passes through the connector 3 and enters the tee 4. The tee 4 then evenly distributes the lubricating oil to the two oil delivery pipes 5.

[0033] The lubricating oil in each oil supply pipe 5 flows through connector 6 and right-angle connector 7 to pressure switch 8. Pressure switch 8 monitors the oil pressure in real time. If the pressure exceeds the preset range, an alarm signal is triggered. The lubricating oil continues to flow through oil distributor 9 to achieve secondary diversion.

[0034] After being diverted by the oil distributor 9, one stream of lubricating oil enters the grease metering element 10. After the grease metering element 10 counts the amount delivered, it is injected into the lubricating felt wheel 13 through the sealing joint 11 and the lubrication pipe 12. The lubricating felt wheel 13 rotates synchronously under the drive of the transmission mechanism, and the adsorbed lubricating oil is evenly applied to the meshing surface or sliding surface of the transmission mechanism.

[0035] Another stream of lubricating oil flows into lubrication pipe 14 through oil distributor 9, and enters the diversion channel of slider 16 through quick connector 15. The limit switch controls slider 16 to slide along guide rail according to the operating status of transmission mechanism, so that lubricating oil is evenly distributed to each lubrication area of ​​transmission mechanism to complete full lubrication.

[0036] Maintenance and debugging:

[0037] Regularly open the sealing cap of the cleaning port 201 of the oil inlet 2, remove the filter tube 203, and take out the filter element for cleaning or replacement to prevent impurities from clogging the leak hole 205 and affecting the oil supply efficiency; observe the lubricating oil consumption through the reading of the grease meter 10, and adjust the output pressure of the lubrication pump 1 according to the lubrication requirements of the transmission mechanism to ensure sufficient oil supply without waste; regularly check the sensitivity of the pressure switch 8. If a pressure alarm occurs, check whether the pipeline is blocked or the joint is leaking, and repair it in time; when the lubrication felt wheel 13 is severely worn, it can be replaced by disassembling the connection between the lubrication tube 12 and the sealing joint 11 to ensure uniform lubrication.

[0038] Working principle:

[0039] When lubricating the transmission of the laser cutting machine, oil is first introduced through the oil inlet 2. The lubricating oil first enters the filter tube 203 through the oil inlet pipe 204, and then enters the connecting pipe 202 and the oil inlet 2 after being filtered by the filter element and the leakage hole 205 inside the filter tube 203. It then enters the lubrication pump 1 through the oil inlet connector 101. After being pressurized, it is output from the oil outlet connector 102, and enters the oil distributor 9 through the connector 1 3, tee 4, oil supply pipe 1 5, connector 2 6, and right angle connector 7. Then, a part of the lubricating oil enters the lubrication felt wheel 13 through the sealing connector 9 and the lubrication pipe 2 12. The rotation of the lubrication felt wheel 13 distributes the lubricating oil to the transmission mechanism to lubricate it. A part of the lubricating oil enters the slider 16 through the lubrication pipe 2 14 and the quick connector 15. A limit switch is installed on the slider 16. The limit switch controls the slider 16 to slide, so that the lubricating oil is distributed evenly.

[0040] The tee 4 divides the lubrication circuit into two parts, left and right. The two parts have the same structure. The top of the oil supply pipe 5 is connected to the tee 4, and the bottom is connected to the connector 6. The connector 6 is connected to the right-angle connector 7. A pressure switch 8 is installed between the right-angle connector 7 and the oil distributor 9. A grease metering element 10 is installed between the oil distributor 9 and the sealing connector 11. One end of the lubrication pipe 12 extends into the interior of the lubrication felt wheel 13, and the other end is connected to the sealing connector 11.
