Description

Technical Field

[0001] This utility model relates to the field of cylinder technology, specifically to a cylinder with stable oil injection. Background Technology

[0002] A cylinder is a cylindrical metal component that guides a piston in a linear reciprocating motion within its casing. In an engine cylinder, air expands, converting thermal energy into mechanical energy; in a compressor cylinder, gas is compressed by a piston, increasing its pressure. The casing of turbines, rotary piston engines, and similar devices is also commonly referred to as a "cylinder." Applications of cylinders include: printing (tension control), semiconductors (spot welding machines, chip grinding), automation control, robotics, and more.

[0003] In the use of cylinders, some cylinders require a relatively stable forward movement. However, traditional cylinders are not easy to maintain stability when moving forward. Therefore, oil-filled cylinders are needed to compensate for this and maintain the stability of the stroke by adding oil.

[0004] However, the refueling cylinder requires the installation of an oil injection component, which is cumbersome to install, has low installation efficiency, and requires good sealing during use.

[0005] Therefore, a cylinder with stable oil injection is needed. Utility Model Content

[0006] The purpose of this invention is to provide a cylinder with stable oil injection, so as to solve the problems mentioned in the background art, such as the cumbersome installation of the oil injection components, low installation efficiency, and the need to ensure good sealing during use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cylinder with stable oil injection, comprising a rear cylinder cover and a base plate, wherein an installation mechanism is fixedly installed on the top surface of the base plate; the installation mechanism includes a fixing sleeve, a retaining ring is fixedly provided on the inner wall of the fixing sleeve, the bottom end face of the fixing sleeve is fixedly connected to the top surface of the base plate, a sealing ring is installed in compression contact on the top surface of the base plate, an installation component is fixedly installed on the top surface of the sealing ring, a bearing sleeve is fixedly installed on the inner wall of the installation component, an installation ring is fixedly installed on the inner wall of the bearing sleeve, a slot is fixedly provided on the side of the installation ring, a sliding sleeve is fixedly installed on the inner bottom surface of the installation component, a sliding rod is slidably installed on the inner wall of the sliding sleeve, and two limiting blocks are installed on the side of the sliding rod.

[0008] Preferably, an oiling component is fixedly installed on the inner wall of the mounting ring, an mounting plate is fixedly installed on the bottom end face of the mounting ring, and a wedge block is fixedly installed on the bottom end face of the mounting plate. There are six wedge blocks, all installed on the bottom end face of the mounting plate, and the included angle between every two wedge blocks is sixty degrees.

[0009] Preferably, a groove is fixedly provided on the side of the wedge block, and slide rails are provided on both the upper and lower sides of the inner wall of the groove.

[0010] Preferably, the inner wall of the slide rail and the inner wall of the limiting block are adapted to each other.

[0011] Preferably, a fixing member is fixedly installed on the side of the rear cylinder head, and the fixing member is fastened to the side of the device by fastening bolts. A tie rod is fixedly installed on the side of the rear cylinder head, and a first connecting pipe is fixedly installed on the top surface of the base plate. The top surface of the first connecting pipe is snapped into the bottom surface of the refueling component.

[0012] Preferably, a front cylinder head is fixedly installed on the end face of the pull rod, and a connecting plate is fixedly installed on the end face of the cylinder push rod.

[0013] Preferably, a second connecting pipe is fixedly installed on the top surface of the refueling component.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) When installing the oil filling component to the cylinder, align the bottom face of the oil filling component with the first connecting pipe and press down on the oil filling component. At the same time, engage the wrench with the bayonet and rotate the mounting ring. The mounting ring drives the mounting plate to rotate, which in turn drives the wedge block to rotate. The wedge block, through the sliding groove and sliding rail, cooperates with the limiting block to push the sliding rod to slide on the inner wall of the sliding sleeve, further extending the mounting part and gradually pressing and contacting the retaining ring opened on the inner wall of the fixed sleeve. When the sliding rod further slides on the inner wall of the sliding sleeve until the sliding rod abuts against the inner wall of the retaining ring, stop rotating the mounting ring to complete the installation of the oil filling component. This solves the problems of cumbersome installation of oil filling components, low installation efficiency, and the need to ensure good sealing during use, thereby improving installation efficiency and further improving the stability of cylinder oil filling.

[0016] 2) During the installation of the oil filling component, the sealing ring of the cylinder is pressed against the top surface of the base plate, thus providing a sealed protection for the connection between the oil filling component and the cylinder. At the same time, the bottom surface of the oil filling component is snapped into the first connecting pipe to form a secondary seal, further improving the sealing effect of the device. Moreover, during installation, only the mounting ring needs to be rotated, making the installation convenient and quick, with high installation efficiency and good sealing performance, which can improve the sealing performance of the device during oil filling and further extend the service life of the device.

[0031] Specifically, during the installation of the refueling component 812, the sealing ring 804 is pressed against the top surface of the base plate 6, thereby providing a sealing protection for the connection between the refueling component 812 and the cylinder. At the same time, the bottom surface of the refueling component 812 is engaged with the first connecting pipe 7 to form a secondary seal, further improving the sealing effect of the device. Moreover, during installation, only the mounting ring 809 needs to be rotated, making the installation convenient, quick, efficient, and with good sealing performance.
