Description

Technical Field:

[0001] This application relates to the technical field of boring machines, and particularly to a contact oiling device applicable to the boring bar of a boring machine. Background Art:

[0002] During the movement of the boring machine, the boring bar of the boring machine is installed in the spindle box and often undergoes telescopic movement. To reduce the mechanical friction of the boring bar in the spindle box, the boring bar needs to be lubricated to ensure smooth operation. Limited by the internal space of the spindle box where the boring bar is located, the equipment accommodated in the spindle box is limited, and the volume of the lubrication device cannot be too large.

[0003] Currently, there are two ways to lubricate the boring bar:

[0004] First, lubrication is carried out by directly dripping oil droplets through an oil pipe. Although this method is simple, the dripping position of the oil droplets is uncertain, the lubrication is uneven, and the oil droplets may splash during the dripping process, easily contaminating the internal space of the spindle box.

[0005] Second, although the ring sleeve contact lubrication scheme has uniform coating, the ring sleeve is always in contact with the boring bar, which will cause continuous frictional heat generation when lubrication is lacking. Content of the Utility Model:

[0006] To solve the above technical problems, the present utility model provides a contact oiling device applicable to the boring bar of a boring machine, and the technical problem to be solved is: the lubricating oil droplets for the boring bar are likely to contaminate the internal space of the spindle box, and continuous frictional heat generation will occur when lubrication is lacking, affecting the machining quality of the boring machine. To solve the above technical problems, the technical solution adopted by the present utility model is:

[0007] A contact oiling device applicable to the boring bar of a boring machine, comprising:

[0008] An oil cylinder movement mechanism, with a reset detection magnetic switch and a protrusion detection magnetic switch respectively arranged at both ends of the outer wall of the oil cylinder movement mechanism;

[0009] An application mechanism for applying oil to the boring bar, and the application mechanism is connected to the oil cylinder movement mechanism;

[0010] A main solenoid valve, a branch solenoid valve, and a lubrication pump. The lubrication pump is connected to the oil port of the oil cylinder movement mechanism through a pipeline in sequence after being connected to the main solenoid valve, and the lubrication pump is connected to the application mechanism through a pipeline in sequence after being connected to the main solenoid valve and the branch solenoid valve to perform the oil injection work on the application mechanism;

[0011] A control device electrically connected to the reset detection magnetic switch, the protrusion detection magnetic switch, the main solenoid valve, the branch solenoid valve, and the lubrication pump.

[0012] Furthermore, the oil cylinder motion mechanism includes an oil cylinder body, a piston, and a piston connecting rod. The piston is arranged in the oil cylinder body in a sliding structure manner. One end of the piston is fixedly connected to one end of the piston connecting rod, and the other end of the piston connecting rod extends outwards through the oil cylinder body and is connected to the coating mechanism.

[0013] A return spring is sleeved outside the piston connecting rod between the piston and the oil cylinder body.

[0014] An oil inlet of the oil cylinder is provided on the oil cylinder body on the side of the piston away from the return spring. The oil inlet of the oil cylinder is connected to the main solenoid valve through a pipeline.

[0015] An oil cylinder return detection magnetic switch and an oil cylinder extension detection magnetic switch are respectively connected to the upper and lower ends outside the oil cylinder body.

[0016] Furthermore, the coating mechanism includes a connecting base, and a sponge is fixedly arranged inside the connecting base.

[0017] Furthermore, an oil inlet is provided on one side of the connecting base, and the oil inlet is connected to the branch solenoid valve through a pipeline.

[0018] Furthermore, an oil storage buffer mechanism is communicatively arranged in the pipeline connecting the oil cylinder body and the main solenoid valve.

[0019] Furthermore, the oil storage buffer mechanism includes an oil storage buffer bottle and a tee base. The oil storage buffer bottle is connected to one path of the tee base, and the other two paths of the tee base are respectively connected to the main solenoid valve and the oil cylinder body through pipelines.

[0020] The beneficial effects of the present utility model are as follows: By means of the branch solenoid valve, a small amount of oil is always maintained in the coating mechanism to lubricate the boring bar, thereby reducing the friction force and wear. Moreover, the oil cylinder motion mechanism and the coating mechanism share the same lubricating pump, and at the same time, the device is separated from the lubricating working surface of the boring bar and the remaining lubricating oil is recovered, reducing the space occupied by more power source devices, facilitating placement in a narrow main spindle box for boring bar lubrication, achieving uniform lubrication of the boring bar, and having high practicability.

[0029] To make the purpose, technical solution and advantages of the implementation of the present utility model clearer, the present utility model will now be further described in detail with reference to the accompanying drawings and the following embodiments, so that the public can better master the implementation method of the present utility model. The specific implementation plan of the present utility model is as follows:

[0030] A contact type oiling device applicable to the boring bar of a boring machine, including an oil cylinder movement mechanism 2. At both ends of the outer wall of the oil cylinder movement mechanism 2, a reset detection magnetic switch 9 and an extension detection magnetic switch 10 are respectively arranged. The oil cylinder movement mechanism 2 is connected to a coating mechanism 1 for oiling the boring bar 21. The lubricating pump 20 is connected to the oil port of the oil cylinder movement mechanism 2 through a pipeline in sequence after being connected to the main solenoid valve 19. The lubricating pump 20 is connected to the coating mechanism 1 through a pipeline in sequence after being connected to the main solenoid valve 19 and the branch solenoid valve 18 for injecting oil into the coating mechanism 1; a control device 5 electrically connected to the reset detection magnetic switch 9, the extension detection magnetic switch 10, the main solenoid valve 19, the branch solenoid valve 18 and the lubricating pump 20; the branch solenoid valve 18 ensures that there is always a small amount of oil in the coating mechanism 1 to lubricate the boring bar 21, thereby reducing the friction force and wear; and the oil cylinder movement mechanism 2 and the coating mechanism 1 share a lubricating pump 20, and at the same time, the device is separated from the boring bar lubrication working surface and the lubricating oil surplus is recovered, reducing the space occupied by more power source devices, facilitating placement in a narrow main spindle box for boring bar lubrication, realizing uniform lubrication of the boring bar, and having high practicability.

[0031] Specifically, the oil cylinder movement mechanism 2 includes an oil cylinder block 11, a piston 13, and a piston connecting rod 15. The piston 13 is arranged in the oil cylinder block 11 in a sliding structure manner. One end of the piston 13 is fixedly connected to the piston connecting rod 15 in a fixed structure manner, and the other end of the piston connecting rod 15 extends outward through the oil cylinder block 11 and is connected to the coating mechanism 1. A return spring 14 is sleeved outside the piston connecting rod 15 between the piston 13 and the oil cylinder block 11, and the return spring 14 is used for the return action of the piston 13. An oil cylinder oil inlet 12 is arranged on the oil cylinder block 11 on the side of the piston 13 away from the return spring 14, and the oil cylinder oil inlet 12 is connected to the main solenoid valve 19 through a pipeline. A return detection magnetic switch 9 and a protrusion detection magnetic switch 10 are respectively connected to the upper and lower ends outside the oil cylinder block 11, and the protrusion and retraction of the piston connecting rod 15 are detected by the two magnetic switches to transmit signals to the control device 5.

[0032] It should be noted that the coating mechanism 1 includes a connection base 6, and a sponge 7 is fixedly arranged in the connection base 6, and the boring bar is lubricated by the oil in the sponge. An oil inlet 8 is arranged on one side of the connection base 6, and the oil inlet 8 is connected to the branch solenoid valve 18 through a pipeline.

[0033] It should be elaborated that an oil storage and buffer mechanism 3 is connected in the pipeline connecting the oil cylinder block 11 and the main solenoid valve 19 to provide temporary storage of lubricating oil and buffer for the oil injection pressure.

[0034] Specifically, the oil storage and buffer mechanism 3 includes an oil storage and buffer bottle 16 and a three-way base 17. The oil storage and buffer bottle 16 is connected to one path of the three-way base 17, and the other two paths of the three-way base 17 are respectively connected to the main solenoid valve 19 and the oil cylinder block 11 through pipelines.

[0035] The working principle and process of the present utility model are as follows:

[0036] Specifically, when in use, as Figure 6 shown in the process flow chart, in combination with Figures 1-5After the initialization of the machine tool control device 5, the reset detection magnetic switch 9 and the extended detection magnetic switch 10 are checked to confirm that the working position is normal. After the check is normal, the oil injection program is executed. The branch solenoid valve 18 and the main solenoid valve 19 are opened simultaneously, and the lubricating pump 20 is started. Using the pressure during oil supply, the piston 13 moves downward under the extrusion of the lubricating oil, and the piston connecting rod 15 drives the coating mechanism 1 to move downward, contacting the boring bar 21 of the boring machine, and the lubricating oil is coated on the boring bar 21. At the same time, the extended detection magnetic switch 10 installed outside the cylinder block 11 of the oil cylinder will give the detected in-place signal to the machine tool control device 5 along with the extension movement of the piston 13; the lubricating pump 20 continues to work for a small set time, and the excess oil is pumped into the oil storage buffer bottle 16 for storage. Subsequently, the branch solenoid valve 18, the main solenoid valve 19 and the lubricating pump 20 are closed simultaneously; when the oil in the coating mechanism is gradually released, the branch solenoid valve 18 is opened to continue to supply a small amount of oil to the coating mechanism 1; when the oil injection time ends, the branch solenoid valve 18 is closed, and the main solenoid valve 19 is opened. The piston 13 is reset under the action of the return spring 14, and the excess oil in the pipeline is recycled into the lubricating pump 20. When the piston 13 reaches the initial position, the reset detection magnetic switch 9 is triggered to give an in-place signal for the control device 5 to judge whether the coating mechanism 1 has disengaged from the lubricating working surface. Subsequently, the main solenoid valve 19 is closed, and a basic oil injection program ends, completing the lubrication of the boring bar of the boring machine by the device.
