Description

Technical Field

[0001] The utility model relates to the technical field of stop cylinders, in particular to a stop cylinder with a buffering effect. Background Art

[0002] In an automatic production line, in order to stop the pallets and workpieces on the production line at each workstation, a stop cylinder is often used for blocking and positioning, so the stop cylinder is also called a blocking cylinder. Since its working stroke is fixed, it is also called a fixed-stroke rod cylinder. When compressed air enters the cylinder, it can push the piston to rise, drive the stop rod to drop, and return the pallet to the production line so that the next workpiece can pass through. When the cylinder is deflated, the stop rod returns to its original position and rises under the action of the torsion spring, causing the pallet to move up, disconnecting the production line and blocking the passage of the workpiece.

[0003] During use, the impact force generated by the lifting of the pallet will directly act on the cylinder, which will be absorbed and borne by the cylinder, affecting the service life of the stop cylinder. Therefore, it is particularly important to design a new stop cylinder with a buffering effect to solve the above-mentioned technical defects and improve the practicality of the overall stop cylinder with a buffering effect.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0024] A stop cylinder with a buffering effect comprises a cylinder body 1, a mounting plate 2 is fixedly connected to the top of the cylinder body 1, a stopper 4 is connected to the mounting plate 2 through a mounting assembly 3, and a buffer assembly 5 is provided at the bottom of the stopper 4 and on both sides of the mounting assembly 3;

[0025] There are mounting grooves 201 at the four corners inside the mounting plate 2, and the inside of the four groups of mounting grooves 201 are all threaded. Two groups of rotating blocks 401 are fixedly connected to the top of the stopper 4, and the inside of the two groups of rotating blocks 401 are rotatably connected to rolling wheels 402.

[0026] Specifically, first, the cylinder body 1 is installed under the pallet, and the cylinder body 1 can drive the block 4 to move, and then the block 4 can drive the pallet to rise and fall. At this time, the installation component 3 connects the block 4 and the cylinder body 1. When the pallet is lifted or lowered, the force it generates acts on the block 4. At this time, the rolling wheel 402 rotates between the two groups of rotating blocks 401, which has a certain buffering effect on the block 4. At the same time, the block 4 has a secondary buffering effect through the buffer component 5 when it is lifted or lowered, which can effectively reduce the force on the block 4 when the pallet is lifted or lowered, thereby improving the service life of the stop cylinder.

[0027] Among them, see Figure 1-Figure 3 , the mounting plate 2 is connected with a stopper 4 through a mounting assembly 3;

[0028] The mounting assembly 3 is used to stably mount the stopper 4. The specific structure of the mounting assembly 3 is as follows:

[0029] The mounting assembly 3 includes two sets of rotating plates 301, a connecting shaft 302, a mounting seat 303, a connecting ring 304, a connecting column 305, a limit block 306, an adjusting rod 307 and a limit seat 308. The two sets of rotating plates 301 are respectively fixedly connected to the top of the mounting plate 2 and are located on the left and right sides of the stop block 4. The connecting shaft 302 is rotatably connected between the two sets of rotating plates 301 and the stop block 4. The top of the mounting plate 2 and the front of the two sets of rotating plates 301 are fixedly connected with the mounting seat 303. The top of the mounting seat 303 is fixedly connected to the mounting plate 2. A connecting ring 304 is fixedly connected, and a connecting column 305 is slidably connected inside the connecting ring 304. Two groups of limit blocks 306 are fixedly connected to the front of the mounting seat 303. An adjusting rod 307 is provided at the top of the mounting plate 2 and between the two groups of limit blocks 306. A limit seat 308 is connected to the top of the mounting seat 303 and behind the adjusting rod 307 through two groups of bolts. The top of the connecting column 305 is connected to the stop block 4, and the driving shaft of the cylinder body 1 passes through the mounting seat 303 and is connected to the connecting column 305.

[0030] Specifically, the stopper 4 is connected through the mounting assembly 3. When the stopper 4 is subjected to the force generated when the pallet is lifted or lowered, the stopper 4 rotates between the two sets of rotating plates 301 through the connecting shaft 302. When in use, the connecting column 305 is driven by the driving shaft of the cylinder body 1 to slide inside the connecting ring 304. At this time, the mounting seat 303 supports the connecting ring 304, and the limit block 306 supports the adjusting rod 307.

[0031] See also Figure 1-Figure 3 , buffer components 5 are provided at the bottom of the stopper 4 and on the left and right sides of the mounting component 3;

[0032] The buffer assembly 5 is used to buffer the stopper 4. The specific structure of the buffer assembly 5 is as follows:

[0033] The buffer assembly 5 includes two groups of buffer seats 501, a sliding groove 502, a first connecting block 503, a second connecting block 504 and a connecting rod 505. The two groups of buffer seats 501 are respectively fixedly connected to the top of the mounting plate 2 and are located on the left and right sides of the mounting assembly 3. Sliding grooves 502 are opened inside the two groups of buffer seats 501. Buffer columns are fixedly connected inside the two groups of sliding grooves 502. Buffer springs are sleeved on the outside of the two groups of buffer columns. The left and right sides of the bottom of the stopper 4 are fixedly connected with the first connecting block 503. The outsides of the two groups of buffer columns are slidably connected with the second connecting block 504. A connecting rod 505 is rotatably connected between the first connecting block 503 and the second connecting block 504.

[0034] Specifically, the buffer assembly 5 has a buffering effect on the block 4. When the block 4 is subjected to a force, the block 4 drives the first connecting block 503 to rise, and then pulls the second connecting block 504 through the connecting rod 505, so that the second connecting block 504 moves inside the sliding groove 502 and on the outside of the buffer column at the same time, and the buffer spring is squeezed by the second connecting block 504, thereby buffering the block 4, thereby preventing the impact force generated when the pallet is lifted and lowered from directly acting on the cylinder body 1.

[0035] In this embodiment, the implementation scenario is specifically as follows: in actual use, the cylinder body 1 is first installed under the pallet, and the cylinder body 1 can drive the block 4 to move, and then the block 4 can drive the pallet to rise and fall. At this time, the installation component 3 connects the block 4 and the cylinder body 1. When the pallet is lifted or lowered, the force generated by it acts on the block 4. At this time, the rolling wheel 402 rotates between the two groups of rotating blocks 401, which has a certain buffering effect on the block 4. At the same time, the block 4 has a secondary buffering effect through the buffer component 5 when it is lifted or lowered, which can effectively reduce the force on the block 4 when the pallet is lifted or lowered, thereby improving the service life of the stop cylinder. Compared with the existing stop cylinder with buffering effect, the utility model can improve the overall practicality of the stop cylinder with buffering effect through design.
