[0001] The utility model relates to the technical field of electric cylinders, in particular to a transverse electric cylinder mechanical system. Background Art

[0002] With the rapid development of electronic lateral movement of warp knitting machines in China, the lateral movement mechanism of warp knitting machines has gradually changed from a mechanical lateral movement mechanism (chain block, disc, etc.) to an electronic lateral movement system. Since the servo motor cannot directly achieve lateral reciprocating motion, the lateral movement electric cylinder mechanism has emerged accordingly. At present, the lateral movement electric cylinder used in the field of electronic lateral movement of warp knitting machines is mostly driven by a servo motor to drive the lead screw to achieve the reciprocating motion of the comb bar.

[0003] During the operation of the screw rod, constant friction will generate high temperature and wear. After a period of use, there will be gaps in the screw rod that affect the accuracy. To ensure accuracy, the screw rod needs to be replaced continuously. Utility Model Content

A servo motor is fixedly mounted in the servo motor mounting seat. The main shaft of the servo motor is connected to the screw drive through a coupling. The screw is horizontally inserted into the hollow part of the piston in the electric cylinder body, and the screw part of the screw drives the piston through the screw nut. A piston oil filling port is provided on the piston, and the piston oil filling port is connected to the hollow part of the piston. An oil outlet is provided at the bottom end of the middle part of the electric cylinder body.

[0007] In addition, a preferred structure is that the connecting shaft of the screw rod is mounted on the screw rod mounting seat through a nut and a bearing to prevent the screw rod from moving forward and backward to ensure the accuracy of the screw rod movement.

[0008] In addition, a preferred structure is that the piston oil filling port is connected to an oil nozzle via a thread, the oil nozzle is connected to an oil pump via an oil pipe, and the oil pump pumps the lubricating oil in the oil pot into the piston oil filling port.

[0011] In addition, a preferred structure is that the screw nut on the screw is fixedly connected to the piston via a screw.

[0012] The beneficial effects of the utility model are:

[0013] The utility model adopts the oil circulation method to cool and lubricate the screw rod, adds an external oil pump, injects clean lubricating oil at room temperature through the piston oil filling port, fills the piston with lubricating oil, and the screw rod is installed inside the piston so that the screw rod is always lubricated with lubricating oil during the action process, and the excess lubricating oil will return to the oil pot through the oil drain port at the bottom of the cylinder body and take away the heat generated by the friction of the screw rod, so that the electric cylinder will not generate a lot of heat during operation, prolonging the service life of related rubber accessories, and the screw rod is immersed in the lubricating oil, which greatly reduces the mechanical wear of the screw rod and increases its service life.

[0015] In the figure: 1 piston oil filling port; 2 electric cylinder body; 3 electric cylinder base; 4 servo motor mounting seat; 5 screw mounting seat; 6 piston; 7 oil drain port; 8 screw. DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Reference Figure 1 The mechanical system of the transverse electric cylinder includes a servo motor mounting seat 4, which is sealed and fixedly mounted on one side of the electric cylinder body 2. A servo motor is fixedly mounted in the servo motor mounting seat 4. The main shaft of the servo motor is connected to the screw rod 8 through a coupling. The screw rod 8 is horizontally inserted in the hollow part of the piston 6 in the electric cylinder body 2, and the screw part of the screw rod 8 drives the piston 6 through a screw nut, wherein the screw nut on the screw rod 8 is fixedly connected to the piston 6 through a screw, and a piston oil filling port 1 is arranged on the piston 6, and the piston oil filling port 1 is communicated with the hollow part of the piston 6, and an oil outlet 7 is arranged at the bottom end of the middle part of the electric cylinder body 2.

[0018] Among them, the electric cylinder body 2 is horizontally installed and fixed on the frame through the electric cylinder base 3, and the connecting shaft of the screw rod 8 is installed on the screw rod mounting seat 5 through a nut and a bearing to prevent the screw rod from moving back and forth to ensure the accuracy of the screw rod movement.

[0019] Moreover, the piston oil filling port 1 is connected with an oil nozzle through a thread, and the oil nozzle is connected to the oil pump through an oil pipe. The oil pump pumps the lubricating oil in the oil pot into the piston oil filling port 1, and the oil outlet 7 is connected with an oil nozzle through a thread, and the oil nozzle returns to the oil pot after filtering through the oil pipe.

[0020] In this embodiment, the main shaft of the servo motor is connected to the screw rod 8 through a coupling to drive the screw rod 8 to rotate, and at the same time, the screw rod 8 drives the piston 6 to move through the screw rod nut to achieve reciprocation.

[0021] At the same time, an oil circulation method is adopted to cool and lubricate the screw rod 8. An external oil pump is added to inject clean lubricating oil at room temperature through the piston oil filling port 1, so that the inside of the piston 6 is filled with lubricating oil. The screw rod 8 is installed inside the piston 1, so that the screw rod 1 is always lubricated with lubricating oil during the action process. The excess lubricating oil will return to the oil pot through the oil drain port 7 at the bottom of the electric cylinder body 2, and at the same time take away the heat generated by the friction of the screw rod, so that the electric cylinder body 2 will not generate a lot of heat during operation, extending the service life of related rubber accessories, and the screw rod is immersed in the lubricating oil, which greatly reduces the mechanical wear of the screw rod and increases its service life.

[0022] Among them, the oil pump pumps the lubricating oil in the oil pot into the interior of the piston 6 through the piston oil filling port 1, so that the screw rod 8 is immersed in the lubricating oil, and the excess lubricating oil will flow out of the piston 6 into the electric cylinder body 2, and then flow out into the oil pot after being filtered through the oil drain port 7 at the bottom of the electric cylinder body 2, thereby realizing the recycling of the lubricating oil.

[0023] The entire transverse electric cylinder mechanical system not only soaks the screw rod 8 in lubricating oil, greatly reducing the mechanical wear of the screw rod 8 and increasing its service life, but also takes away the heat generated by the friction of the screw rod 8, so that the electric cylinder body 2 does not generate a large amount of heat during operation, thereby extending the service life of related rubber accessories.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
