Description

Technical Field

[0001] The present invention belongs to the technical field of module oil injection, and more specifically, relates to a linear module with an automatic oil injection function. Background Art

[0002] A linear module is an automated upgrade unit that realizes the linear motion of a load through the combination of various units, which can make the automated motion of the load more flexible and the positioning more accurate.

[0003] The structure of a linear module mainly includes a guide rail and a sliding table that reciprocates along the guide rail. The sliding table needs to be regularly oiled to reduce the frictional resistance and frictional wear during its operation and ensure the stability of the operation. The existing measures for oiling the sliding table are to open an oil injection port on the sliding table for manual oil injection during shutdown or to connect the oil injection port to an external oil pump through an oil pipe to achieve oil injection. However, in the above measures, the operation of manual oil injection is time-consuming and laborious, and if the operation is improper, it will cause oil leakage, resulting in the pollution of the linear module. Moreover, the oil pipe needs to be limited by a drag chain. During the process of the drag chain following the high-speed movement of the sliding table, it will squeeze the oil pipe, causing the oil pipe to rupture and leak oil, affecting the oil injection of the sliding table, and thus it is difficult to ensure the stability of the sliding table during operation.

[0004] Therefore, how to design an oil injection measure that can facilitate the oil injection of the sliding table has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that the existing measures for oiling the sliding table have poor oil injection effect and it is difficult to ensure the stability of the sliding table during operation.

[0006] To achieve the above purpose, the present invention provides a linear module with an automatic oil injection function, including a guide rail, a motion module, and an oil injection module;

[0007] One end of the guide rail has a mounting plate;

[0008] The motion module includes a sliding table connected to the guide rail and a sliding table drive unit for driving the sliding table to reciprocate along the guide rail. An oil injection joint is provided at one end of the sliding table;

[0009] The oil injection module includes an oil cylinder and a piston rod. The oil cylinder is fixedly arranged on the side of the mounting plate facing the oil injection joint. One end of the piston rod with a piston is axially movably connected to the inside of the oil cylinder, and an oil delivery channel is provided inside the piston rod;

[0010] The oil injection joint can be connected to the oil cylinder through the oil delivery channel.

[0011] Optionally, the oil delivery channel includes a first channel and a second channel that are sequentially arranged in the piston column along a direction away from the oil cylinder. An oil inlet hole for communicating with the oil cylinder is provided in the first channel, and the second channel communicates with the first channel.

[0012] Optionally, the second channel is a flat oil nozzle adapted to the structure of the oil injection joint.

[0013] Optionally, a limiting plate is provided on the outer wall of the end of the piston column away from the oil cylinder. A spring for resetting the piston column is connected to the limiting plate, and one end of the spring is fixedly connected to the oil cylinder.

[0014] Optionally, a first sealing ring, a second sealing ring, and a third sealing ring for preventing oil leakage are sequentially arranged in the oil cylinder along its oil outlet direction.

[0015] Optionally, one end of the oil cylinder away from the piston column is communicated with an oil inlet pipe, and one end of the oil inlet pipe penetrates and extends beyond the mounting plate for communicating with an external oil pump.

[0016] Optionally, the external oil pump has an oil pump drive unit, and the oil pump drive unit is communicatively connected to the slide drive unit.

[0017] Optionally, an oil inlet channel communicating with the oil injection joint is provided in the slide, and the oil inlet channel is used to deliver the oil to the lubrication area to be lubricated of the slide.

[0018] Optionally, the guide rail includes a frame, a first track, and a second track, and the first track and the second track are oppositely and parallelly arranged on the frame.

[0019] The beneficial effects of the present invention are as follows:

[0020] The linear module with an automatic oil injection function proposed by the present invention is provided with an oil injection joint at one end of the slide, and an oil cylinder and a piston column axially movably connected in the oil cylinder are provided on the side of the mounting plate facing the oil injection joint. When the slide moves to the position of the oil cylinder under the drive of the slide drive unit, the oil injection joint can communicate with the oil cylinder through the oil delivery channel in the piston column, so as to facilitate oil injection into the slide. Compared with the existing measures for oil injection into the slide, the slide of the linear module of the present invention can be automatically oil-injected under the drive of the slide drive unit, and can avoid the problem of oil leakage caused by improper operation or structural defects. The oil injection effect is good, so as to ensure the stability of the slide during operation.

[0049] Referring to Figures 1-4 , an embodiment of the present invention provides a linear module with an automatic oil injection function, including a guide rail, a motion module and an oil injection module;

[0050] One end of the guide rail has a mounting plate 1;

[0051] The motion module includes a slide table 2 connected to the guide rail and a slide table drive unit for driving the slide table 2 to reciprocate along the guide rail. One end of the slide table 2 is provided with an oil injection joint 3;

[0052] The oil injection module includes an oil cylinder 4 and a piston rod 5. The oil cylinder 4 is fixedly arranged on the side of the mounting plate 1 facing the oil injection joint 3. One end of the piston rod 5 with a piston is axially movably connected to the inside of the oil cylinder 4, and the piston rod 5 has an oil delivery channel;

[0053] The oil injection joint 3 can be communicated with the oil cylinder 4 through the oil delivery channel.

[0054] In one embodiment, the guide rail includes a frame 6, a first rail 7, and a second rail 8. The first rail 7 and the second rail 8 are arranged opposite and parallel to each other on the frame 6. Specifically, the slide table is mounted on the first rail and the second rail, and the slide table drive unit is arranged inside the slide table to drive the slide table to reciprocate on the first rail and the second rail.

[0055] In one embodiment, an oil inlet passage communicating with the oil injection joint 3 is arranged inside the slide table 2. The oil inlet passage is used to transport the oil fluid to the lubrication area to be lubricated of the slide table 2.

[0056] In one embodiment, the oil delivery passage includes a first passage 9 and a second passage 10 that are sequentially arranged inside the piston rod 5 along the direction away from the oil cylinder 4. An oil inlet hole 11 for communicating with the oil cylinder 4 is arranged inside the first passage 9, and the second passage 10 communicates with the first passage 9.

[0057] In a specific embodiment, the second passage 10 is a flat head oil nozzle adapted to the structure of the oil injection joint 3.

[0058] In one embodiment, a limiting plate 51 is arranged on the outer wall of the end of the piston rod 5 away from the oil cylinder 4. A spring 12 for resetting the piston rod 5 is connected to the limiting plate 51, and one end of the spring 12 is fixedly connected to the oil cylinder 4.

[0059] Specifically, when the slide table is driven by the slide table drive unit to drive the oil injection joint close to the oil injection module and dock with the flat head oil nozzle, it can further push the piston rod towards the oil cylinder direction, causing the spring to compress and the oil inlet hole to be exposed inside the oil cylinder. The oil injection joint communicates with the oil cylinder, and after the oil fluid enters the oil injection joint through the oil delivery passage, it is injected into the slide table. After the oil injection is completed, the oil injection joint retracts, and the spring drives the piston rod to reset, the oil inlet hole moves away from the oil cylinder, and the oil cylinder returns to the closed state, waiting for the next oil injection operation.

[0060] In a specific embodiment, a first sealing ring 13, a second sealing ring 14, and a third sealing ring 15, all of which are used to prevent oil fluid leakage, are sequentially arranged inside the oil cylinder 4 along its oil outlet direction.

[0061] In a specific embodiment, an oil inlet pipe 16 is connected to the end of the oil cylinder 4 away from the piston rod 5. One end of the oil inlet pipe 16 penetrates and extends beyond the mounting plate 1 for communicating with an external oil pump.

[0062] In a specific embodiment, the external oil pump has an oil pump drive unit, and the oil pump drive unit is communicatively connected to the slide table drive unit. The slide table drive unit is communicatively connected to the host computer. Thus, when the host computer outputs a control signal to the slide table drive unit, the slide table drive unit can transmit the control signal to the oil pump drive unit, so that the slide table drive and the external oil pump drive are carried out simultaneously, avoiding the situation of oil injection failure caused by insufficient oil fluid volume in the oil cylinder, and realizing efficient oil injection for the slide table.

[0063] In a specific embodiment, the external oil pump further has an oil output monitoring unit, and the oil output monitoring unit is communicatively connected to the host computer for controlling the amount of oil output by the external oil pump.

[0064] The linear module with an automatic oil injection function proposed by the present invention is provided with an oil injection joint at one end of the slide table, and an oil cylinder and a piston column axially movably connected in the oil cylinder are arranged on the side of the mounting plate facing the oil injection joint. When the slide table moves to the position of the oil cylinder driven by the slide table driving unit, the oil injection joint can communicate with the oil cylinder through the oil delivery channel in the piston column, so as to facilitate the oil injection of the slide table.

[0065] Furthermore, by communicatively connecting the oil pump driving unit with the slide table driving unit, the slide table driving enables the simultaneous operation of the slide table driving and the external oil pump driving, avoiding the occurrence of oil injection failure caused by insufficient oil volume in the oil cylinder, and realizing efficient oil injection of the slide table.

[0066] Compared with the existing measures for oil injection of the slide table, the slide table of the linear module of the present invention can be automatically oil-injected under the drive of the slide table driving unit, and can avoid the problem of oil leakage caused by improper operation or structural defects. The oil injection effect is good and the efficiency is high, so as to ensure the stability of the slide table during operation.
