[0003] In order to increase the smoothness of sliding and reduce the friction between the stator and the mover of the linear motor, the staff needs to add lubricating oil. However, the operation of manually adding lubricating oil by the staff is too frequent, which will cause too much lubricating oil to be added, resulting in too much lubricating oil leaking from the connecting seat and causing waste of lubricating oil. Content of the Utility Model

[0012] Firstly, according to the installation width of the connection seats at both ends of the stator, the connection blocks at both ends of the oil collecting cabinet are pulled by the telescopic rod and the telescopic spring. The connection blocks stretch the telescopic rod and the telescopic spring to generate tensile stress. When the connection blocks are pulled to the width of the connection seats, the clamping blocks are clamped at both ends of the connection seats. At this time, the tensile stress of the telescopic rod and the telescopic spring causes the clamping blocks to approach both ends of the connection seats and clamp the oil collecting cabinet at both ends of the connection seats. At the same time, the wear-resistant lining plate can increase the clamping and fixing friction force between the clamping blocks and the connection seats, enhancing the stability of clamping and fixing. The telescopic rod and the telescopic spring can be used for clamping and fixing connection seats with different widths.

[0013] The filter screen plate is slidably clamped inside the oil collecting cabinet between two groups of fixed seats through the clamping slide rod. The filter screen plate can filter metal particles in the lubricating oil leaking from the stator, increasing the purity of the lubricating oil and its service life. At the same time, the clamping slide rod facilitates the replacement and cleaning of the filter screen plate. Then, the sealing plate is slidably connected inside the oil collecting cabinet. The sealing blocks on the outer periphery of the sealing plate and the sealing groove inside the oil collecting cabinet can seal the oil collecting cabinet, reducing the leakage of lubricating oil. The oil collecting cabinet can prevent excessive lubricating oil addition by the staff due to excessive operation, thus avoiding waste of lubricating oil. At the same time, the clamping blocks at both ends of the oil collecting cabinet facilitate the installation and disassembly of the oil collecting cabinet. By removing the sealing plug at the bottom of the oil collecting cabinet, it is convenient for the staff to take out the lubricating oil inside the oil collecting cabinet.

[0021] Refer to Figures 1 to 4, in the embodiment of the present utility model, an oil-collecting linear motor includes a linear motor body 1. The linear motor body 1 includes a stator 11 and a mover 12 slidably connected to the top of the stator 11. Connecting seats 13 are symmetrically and fixedly provided at both ends of the stator 11, and oil outlet pipes 14 are symmetrically arranged at one end of the connecting seats 13. An oil-collecting assembly 2 is arranged at one end of the connecting seat 13. The oil-collecting assembly 2 includes an oil-collecting cabinet 21 and oil inlet holes 22 symmetrically opened at one end of the oil-collecting cabinet 21 and close to one end of the connecting seat 13. The oil inlet holes 22 are adapted to the oil outlet pipes 14. A discharge hole 23 for discharging lubricating oil is opened at the bottom end of the oil-collecting cabinet 21, and a sealing plug 24 is inserted at the bottom end of the discharge hole 23. Connecting blocks 25 are arranged at both ends of the oil-collecting cabinet 21, and a clamping block 26 fixedly connected to and abutting against the connecting seat 13 is fixedly provided at one end of the connecting block 25. A filtering assembly 3 for filtering lubricating oil impurities is arranged inside the oil-collecting cabinet 21.

[0022] Refer to Figure 1 and Figure 4 , at one end of the oil-collecting cabinet 21 close to the connecting block 25, a telescopic rod 28 fixedly connected to the connecting block 25 is fixedly provided, and a telescopic spring 29 for providing clamping force is sleeved on the outer periphery of the telescopic rod 28. The telescopic rods 28 are symmetrically arranged at one end of the connecting block 25, and a wear-resistant lining plate 27 for increasing the stability of the oil-collecting cabinet 21 and the connecting seat 13 is fixedly provided at one end of the clamping block 26.

[0023] Refer to Figure 2 and Figure 3 , the filtering assembly 3 includes fixing seats 31 symmetrically and fixedly installed inside the oil-collecting cabinet 21. A filter mesh plate 32 is slidably connected inside the oil-collecting cabinet 21 at one end of the fixing seat 31. A clamping slide rod 33 slidably connected to the fixing seat 31 is fixedly provided at one end of the filter mesh plate 32, and the clamping slide rods 33 are symmetrically fixedly provided at both ends of the filter mesh plate 32. A sealing plate 34 for sealing the oil-collecting cabinet 21 is slidably connected at one end of the oil-collecting cabinet 21, and sealing blocks 36 for increasing the sealing performance of the oil-collecting cabinet 21 are evenly fixedly provided on the outer periphery of the sealing plate 34. A sealing groove 35 for embedding the sealing blocks 36 is opened inside the oil-collecting cabinet 21.

[0024] The working principle of the present utility model is as follows: First, according to the installation width of the connecting seats 13 at both ends of the stator 11, the connecting blocks 25 at both ends of the oil collecting cabinet 21 are pulled by the telescopic rod 28 and the telescopic spring 29. The connecting block 25 stretches the telescopic rod 28 and the telescopic spring 29 to generate tensile stress. When the connecting block 25 is pulled to the width of the connecting seat 13, the clamping blocks 26 are clamped at both ends of the connecting seat 13. At this time, the tensile stress of the telescopic rod 28 and the telescopic spring 29 makes the clamping blocks 26 approach both ends of the connecting seat 13 and clamp and fix the oil collecting cabinet 21 at both ends of the connecting seat 13. At the same time, the wear-resistant lining plate 27 can increase the clamping and fixing friction force between the clamping block 26 and the connecting seat 13, and increase the stability of clamping and fixing. The telescopic rod 28 and the telescopic spring 29 can be clamped and fixed according to the connecting seats 13 of different widths. After that, the filter screen plate 32 is slidably clamped into the middle of the two fixing seats 31 inside the oil collecting cabinet 21 through the clamping slide rod 33. The filter screen plate 32 can filter out the metal particles in the lubricating oil leaking from the inside of the stator 11, increase the purity of the lubricating oil, and increase the service life. At the same time, the clamping slide rod 33 can facilitate the replacement and cleaning of the filter screen plate 32. After that, the sealing plate 34 is slidably connected to the inside of the oil collecting cabinet 21. The sealing block 36 on the outer periphery of the sealing plate 34 and the sealing groove 35 inside the oil collecting cabinet 21 can seal the oil collecting cabinet 21, reduce the leakage of the lubricating oil. The oil collecting cabinet 21 can reduce the situation that the staff adds too much lubricating oil due to excessive operation, which in turn leads to waste of lubricating oil. At the same time, the clamping blocks 26 at both ends of the oil collecting cabinet 21 can facilitate the installation and disassembly of the oil collecting cabinet 21. By removing the sealing plug 24 at the bottom of the oil collecting cabinet 21, it is convenient for the staff to take out the lubricating oil in the oil collecting cabinet 21.
