Description

Technical Field

[0001] This utility model relates to the field of slide cylinders with quick replacement of magnetic sealing rings. Background Technology

[0002] In the field of automation equipment, slide cylinders are widely used as core actuators in scenarios such as workpiece positioning, handling, and clamping. The sealing rings of traditional slide cylinders are usually installed using snap-fit, threaded, or interference fit.

[0003] However, traditional magnetic sliding cylinders rely solely on magnetic force to fix the sealing ring. When subjected to high vibration, strong impact, or high-frequency reciprocating motion, the magnetic force is insufficient to constrain the position of the sealing ring, which can easily lead to displacement, deformation, or even detachment of the sealing ring. Under complex working conditions, such as high temperature, high dust, and humid environments, traditional magnetic sealing rings are prone to demagnetization of the magnet, adsorption of impurities, or material aging, which can reduce sealing performance and fixing effect. Although traditional magnetic sealing rings are easy to replace quickly, they lack positioning assistance, making it difficult to ensure accurate alignment during installation. This can lead to localized poor sealing due to misalignment of the sealing ring, increasing the probability of repeated adjustments and secondary maintenance.

[0004] Therefore, we propose a slide cylinder with a magnetically attached seal ring for quick replacement. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a slide cylinder for quick replacement of magnetic sealing rings. Through the lead screw and threaded sleeve transmission structure in the positioning component, the lead screw and threaded sleeve cooperate with the first connecting bar and the second connecting bar of the linkage mechanism. Rotating the knob can drive the threaded sleeve to move back and forth. Through the connecting rod, the abutment bar is pushed to extend or retract along the slide bar. After the abutment bar is embedded in the groove at the rear end of the connecting block, a lateral clamping force can be applied to the mounting component containing the magnetic sealing ring from both sides, which makes up for the inadequacy of simple magnetic attraction under vibration and impact conditions and prevents the sealing ring from shifting or falling off.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A slide cylinder with a magnetic seal ring for quick replacement includes a slide cylinder assembly, a mounting component is provided at the rear end of the slide cylinder assembly, and positioning components are provided at the left and right ends of the mounting component.

[0008] The positioning component includes a mounting block, a limiting ring fixedly connected to the front end of the mounting block, a plurality of equidistant sliding rods slidably connected inside the limiting ring, an abutment strip fixedly connected to the front end of each sliding rod, a second connecting rod fixedly connected to the inner end of each abutment strip, a lead screw rotatably connected to the middle of the mounting block, a threaded sleeve threadedly connected to the rear end of the lead screw through the limiting ring, and a first connecting rod fixedly connected to the outer end of the threaded sleeve, each corresponding to one of the second connecting rods. A connecting rod is hinged between the second connecting rod and the first connecting rod.

[0009] Furthermore, a knob is fixedly connected to the outer end of the mounting block, and the knob is fixedly connected to the lead screw.

[0010] Furthermore, the slide cylinder assembly includes two symmetrically arranged connecting blocks, with a guide rod fixedly connected between the two connecting blocks. A piston rod fixedly connected to the connecting blocks is provided on the rear side of the guide rod, and a high-precision slider is slidably connected to the middle of the piston rod. The middle of the high-precision slider is slidably connected to the guide rod.

[0011] Furthermore, two symmetrical rubber anti-collision strips are fixedly connected to the inner end of the connecting block.

[0012] Furthermore, the mounting assembly includes a fixing mounting strip adapted to the connecting block, and the front end of the fixing mounting strip is fixedly connected to a magnetic external sealing ring adapted to the piston rod.

[0013] Furthermore, the rear end of the connecting block is provided with a groove that matches the abutment strip.

[0014] Furthermore, the magnetic external sealing ring is slidably connected to the high-precision slider.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. This solution utilizes a lead screw and threaded sleeve transmission structure in the positioning component. The lead screw and threaded sleeve cooperate with the first connecting bar and the second connecting bar of the linkage mechanism. Rotating the knob can drive the threaded sleeve to move back and forth. The connecting bar pushes the abutment bar to extend or retract along the slide bar. After the abutment bar is embedded in the groove at the rear end of the connecting block, it can apply a lateral clamping force to the mounting component containing the magnetic sealing ring from both sides. This compensates for the inadequacy of simple magnetic attraction under vibration and impact conditions, preventing the sealing ring from shifting or falling off. For example, in high-frequency reciprocating motion scenarios, mechanical clamping and magnetic attraction form a dual constraint, improving sealing reliability.

[0017] 2. This solution uses the installation components to coordinate with the positioning components. When replacing the magnetic external sealing ring, you only need to manually turn the knob to drive the gap between the multiple abutment strips to reduce the distance. The old sealing ring can be directly removed and the new part installed without the need for screwdrivers or other tools, which greatly shortens the maintenance time. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] Reference Figures 1-5 As shown, the slide cylinder for quick replacement of magnetic sealing ring in a preferred embodiment of the present invention includes a slide cylinder assembly 1, an installation assembly 2 is provided at the rear end of the slide cylinder assembly 1, and positioning assemblies 3 are provided at the left and right ends of the installation assembly 2.

[0027] The positioning component 3 includes a mounting block 301. A limiting ring 302 is fixedly connected to the front end of the mounting block 301. Multiple equally spaced slide rods 310 are slidably connected inside the limiting ring 302. An abutment strip 309 is fixedly connected to the front end of the slide rod 310. A second connecting strip 308 is fixedly connected to the inner end of the abutment strip 309. A lead screw 303 is rotatably connected to the middle of the mounting block 301. The rear end of the lead screw 303 passes through the limiting ring 302 and is threadedly connected to a threaded sleeve 305. A first connecting strip 306, corresponding one-to-one with the second connecting strip 308, is fixedly connected to the outer end of the threaded sleeve 305. A connecting rod 307 is hinged between the second connecting strip 308 and the first connecting strip 306.

[0028] A knob 304 is fixedly connected to the outer end of the mounting block 301, and the knob 304 is fixedly connected to the lead screw 303.

[0029] This solution is achieved through the collaboration of components such as knob 304, lead screw 303, screw sleeve 305, first connecting bar 306, connecting rod 307, second connecting bar 308, slide bar 310, and abutment bar 309. Rotating the knob 304 drives the lead screw 303 to rotate. The lead screw 303 and the threaded sleeve 305 are driven by the thread, causing the threaded sleeve 305 to move. Through the linkage mechanism composed of the first connecting bar 306, the connecting rod 307 and the second connecting bar 308, the abutment bar 309 is pushed to extend along the slide bar 310 and embed into the rear groove of the connecting block 101. A lateral clamping force is applied to the mounting assembly 2 from both sides to compensate for insufficient magnetic attraction and prevent the magnetic external sealing ring 202 from shifting or falling off. This is achieved by the knob 304, lead screw 303, threaded sleeve 305, first connecting bar 306, connecting rod 307, second connecting bar 308, slide bar 310, abutment bar 309, fixed mounting bar 201 and magnetic external sealing ring 202. When replacing, turn the knob 304 to rotate the lead screw 303, which drives the screw sleeve 305 to move. Through the linkage mechanism, the abutment strip 309 retracts, releasing the clamping of the fixed mounting strip 201. Thus, the magnetic external sealing ring 202 can be directly removed and installed without tools, achieving quick replacement.

[0030] The slide cylinder assembly 1 includes two symmetrically arranged connecting blocks 101. A guide rod 102 is fixedly connected between the two connecting blocks 101. A piston rod 103 is fixedly connected to the connecting blocks 101 on the rear side of the guide rod 102. A high-precision slider 105 is slidably connected to the middle of the piston rod 103. The middle of the high-precision slider 105 is slidably connected to the guide rod 102.

[0031] Two symmetrical rubber anti-collision strips 104 are fixedly connected to the inner end of the connecting block 101.

[0032] Mounting assembly 2 includes a mounting strip 201 adapted to the connecting block 101, and a magnetic external sealing ring 202 adapted to the piston rod 103 is fixedly connected to the front end of the mounting strip 201.

[0033] The rear end of the connecting block 101 has a groove that matches the abutment strip 309.

[0034] The magnetic external sealing ring 202 is slidably connected to the high-precision slider 105.

[0035] Specific implementation process: When the slide cylinder for quick replacement of magnetic sealing rings is working, the positioning component 3 first takes effect. The operator rotates the knob 304, which drives the lead screw 303 to rotate. The lead screw 303 engages with the threaded sleeve 305, causing the sleeve 305 to move back and forth along the lead screw 303. As the sleeve 305 moves, it pushes the abutment bar 309 to extend or retract along the slide rod 310 through the first connecting bar 306, the connecting rod 307, and the second connecting bar 308. When the abutment strip 309 is embedded in the groove at the rear end of the connecting block 101, a lateral clamping force is applied to the mounting component 2, including the magnetic external sealing ring 202, from both sides. This compensates for the inadequacy of simple magnetic attraction under vibration and impact conditions, ensuring that the magnetic external sealing ring 202 will not shift or fall off under complex conditions. In the mounting component 2, the fixed mounting strip 201 is adapted to the connecting block 101, and the magnetic external sealing ring 202 is fixed to the front end of the fixed mounting strip 201 and adapted to the piston rod 103. When the magnetic external sealing ring 202 needs to be replaced, the knob 304 is turned to retract the abutment strip 309, and the old sealing ring can be directly removed and the new part installed without the need for screwdrivers or other tools, achieving quick replacement. When the slide cylinder assembly 1 is working, the piston rod 103 performs telescopic movement under the action of external power, and the high-precision slider 105 slides along the guide rod 102 and the piston rod 103 to achieve linear movement of the slide. The rubber anti-collision strip 104 at the inner end of the connecting block 101 can act as a buffer when the slide table moves to the limit position, reducing the impact of collision. The magnetic external sealing ring 202 is slidably connected to the high-precision slider 105 to ensure the sealing of the piston rod 103 during the movement of the slide table, prevent gas leakage, and ensure the stable and efficient operation of the slide table cylinder.
