Description

Technical Field

[0001] The utility model relates to the technical field of cylinders and discloses a cylinder piston with a buffer function. Background Art

[0002] The cylinder is a pneumatic component. A piston and a piston rod are arranged inside the cylinder. The piston and the piston rod are connected to each other. When compressed air is introduced into the cylinder, the piston can move inside the cylinder under the action of pneumatic force, thereby driving the piston rod to move. Different components can be installed on the end of the piston rod outside the cylinder to complete tasks such as clamping.

[0003] The existing cylinder piston is usually provided with a magnetic ring on the outside, and a corresponding sensor is provided on the cylinder. The position of the cylinder piston can be obtained according to the position of the magnetic ring, and the cylinder piston is prevented from colliding with the inner wall of the cylinder through the corresponding control component. However, when the corresponding sensor or sensing component fails, the piston is likely to collide with the inner wall of the cylinder and be damaged by a large impact. The outer wall of the cylinder piston is usually embedded with a sealing ring for sealing. The sealing ring may be detached from the outer wall of the cylinder piston and damaged when the cylinder piston moves, thereby affecting the airtightness between the cylinder piston and the cylinder. Utility Model Content

[0004] The purpose of the utility model is to provide a cylinder piston with a buffering function in view of the above-mentioned problems and shortcomings, so as to effectively protect the plug body and better ensure the stability of the sealing ring installation.

[0005] A cylinder piston with a buffering function comprises a plug body, and sealing rings are arranged on the left and right sides of the plug body;

[0006] The left and right ends of the outer wall of the plug body are provided with grooves, and the two sealing rings are respectively embedded and connected in the two grooves. Ring plates are provided on the left and right sides of the plug body, and the ring plates are connected to the plug body. Buffer components are provided on the outside of the two ring plates. The left and right sides of the outer wall of the plug body are provided with a plurality of limiting grooves distributed in an annular shape and at equal intervals. The limiting grooves pass through the adjacent sealing rings. A plurality of limiting rods are connected to the inner side of the ring plate, and the limiting rods are inserted into the adjacent limiting grooves.

[0007] Preferably, a magnetic ring is embedded and installed in the middle of the outer wall of the plug body.

[0008] Preferably, a piston rod is provided in the middle of the plug body, a plurality of threaded holes equidistantly distributed in a ring shape are opened on the left and right sides of the outer wall of the plug body, a plurality of bolts are threadedly connected on the ring plate, and the bolts are screwed into the adjacent threaded holes.

[0009] Preferably, the buffer assembly comprises a buffer pad and a rubber ring, and the buffer pad is welded to an outer side of the ring plate.

[0010] Preferably, the rubber ring is welded between the buffer pad and the outer portion of the ring plate.

[0011] Beneficial effects of the utility model:

[0012] Before the use of the cylinder piston with buffer function, grooves are opened on the left and right ends of the outer wall of the plug body, and two sealing rings are respectively welded inside the two grooves to ensure that the limiting grooves on the sealing rings correspond to the opening positions on the plug body. The grooves can limit the sealing rings to a certain extent. Several bolts are threadedly connected on the ring plate. The limiting rods correspond to the limiting grooves and the bolts correspond to the threaded holes. At this time, the bolts are screwed into the threaded holes to complete the connection between the ring plate and the plug body. At the same time, the limiting rods are inserted into the corresponding limiting grooves. The limiting rods can limit the sealing rings, thereby preventing the subsequent plug body from falling out of the grooves when moving inside the cylinder.

[0013] The plug body and the piston rod are both located inside the cylinder. When the plug body is located inside the cylinder, the sealing ring on the plug body can fit with the inner wall of the cylinder. The magnetic ring arranged on the plug body cooperates with the sensor arranged on the cylinder to display the position of the plug body, thereby controlling the plug body not to collide with the cylinder wall and be damaged. This is the prior art. When a failure occurs to a related control component inside the cylinder, since the buffer pad fits onto the outer side of the ring plate, the rubber ring is welded between the buffer pad and the outer side of the ring plate, and the material of the buffer pad and the rubber ring are both rubber, the rubber can achieve a buffering effect. The buffer pads on the ring plates on the left and right sides of the plug body can effectively buffer the left and right sides of the plug body to a certain extent, thereby protecting the plug body. The rubber ring can protect the area around the ring plate and effectively enhance the stability of the buffer pad. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figures 1 to 3 As shown, the present application is a cylinder piston with a buffering function, comprising a plug body 1, and sealing rings 3 are provided on the left and right sides of the outside of the plug body 1;

[0019] The left and right ends of the outer wall of the plug body 1 are provided with grooves 6, and the two sealing rings 3 are respectively embedded and connected in the two grooves 6. The left and right sides of the plug body 1 are provided with ring plates 5, and the ring plates 5 are connected to the plug body 1. The two ring plates 5 are provided with buffer components on the outside. The left and right sides of the outer wall of the plug body 1 are provided with a plurality of limiting grooves 7 distributed in an annular shape and at equal intervals, and the limiting grooves 7 penetrate the adjacent sealing rings 3. The inner side of the ring plate 5 is connected with a plurality of limiting rods 8, and the limiting rods 8 are inserted into the adjacent limiting grooves 7;

[0020] A piston rod 2 is provided in the middle of the plug body 1, and a plurality of threaded holes 9 are opened on the left and right sides of the outer wall of the plug body 1 and are distributed in an annular shape and at equal intervals. A plurality of bolts 10 are threadedly connected to the ring plate 5, and the bolts 10 are screwed into the adjacent threaded holes 9. A magnetic ring 4 is embedded and installed in the middle of the outer wall of the plug body 1;

[0021] Before the cylinder piston with buffer function is used, grooves 6 are opened at the left and right ends of the outer wall of the plug body 1, and two sealing rings 3 are respectively welded inside the two grooves 6. Figure 3 As shown, it is ensured that the limiting groove 7 on the sealing ring 3 corresponds to the position of the opening on the plug body 1, and the groove 6 can limit the sealing ring 3 to a certain extent. A plurality of bolts 10 are threadedly connected to the ring plate 5. The limiting rod 8 corresponds to the limiting groove 7 and the bolt 10 corresponds to the threaded hole 9. At this time, the bolt 10 is screwed into the threaded hole 9 to complete the connection between the ring plate 5 and the plug body 1. When the connection between the ring plate 5 and the plug body 1 is completed, the limiting rod 8 is inserted into the corresponding limiting groove 7. The limiting rod 8 can limit the sealing ring 3, thereby preventing the plug body 1 from falling out of the groove 6 when it moves inside the cylinder later.

[0022] The buffer assembly includes a buffer pad 11 and a rubber ring 12. The buffer pad 11 is welded to the outer side of the ring plate 5, and the rubber ring 12 is welded between the buffer pad 11 and the outer side of the ring plate 5.

The control component on the cylinder controls the plug body 1 not to collide with the cylinder wall and be damaged, which is the prior art. When the relevant control components inside the cylinder fail, since the buffer pad 11 fits against the outer side of the ring plate 5, the rubber ring 12 is welded between the buffer pad 11 and the outer side of the ring plate 5, and the material of the buffer pad 11 and the rubber ring 12 are both rubber, the rubber can achieve a buffering effect, and the buffer pad 11 on the ring plates 5 on the left and right sides of the plug body 1 can effectively buffer the left and right sides of the plug body 1 to a certain extent, thereby protecting the plug body 1, and the rubber ring 12 can protect the area around the ring plate 5, and effectively enhance the stability of the buffer pad 11.
