DETAILED DESCRIPTION

[0023] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0024] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0025] In the description of the present application, it should be noted that the terms used herein are only for the purpose of describing the specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For the convenience of description, the size of each part shown in the drawings is not drawn according to the actual proportional relationship. The technology, method and equipment known to those skilled in the art may not be discussed in detail, but under appropriate circumstances, the technology, method and equipment should be regarded as part of the authorized description. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, and not as a limitation. Therefore, other examples of exemplary embodiments can have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0026] As shown in the accompanying drawings Figure 1 , the accompanying drawings Figure 2 , and the accompanying drawings Figure 3 , a kind of forked executor position buffer device, including cylinder 4, first end plate 8 and second end plate 3, first end plate 8 and second end plate 3 are respectively arranged at the both ends of cylinder 4, sliding seal is provided with plug plate 6 in cylinder 4, plug plate 6 is connected with plug rod 5, plug rod 5 and second end plate 3 sliding seal together, further include bushing seat 9 and sealing plug 7, first end plate 8 is provided with first through-hole 801, second end plate 3 is provided with breathing port, bushing seat 9 is arranged on first end plate 8, bushing seat 9 is barrel-shaped, and second through-hole 901 is formed at the barrel bottom of bushing seat 9, the aperture of first through-hole 801 is less than the aperture of second through-hole 901, sealing plug 7 is arranged on plug rod 5, and sealing plug 7 is located between first end plate 8 and plug plate 6.

[0027] In the position buffer device, two cavities can be formed, the first cavity 80 is formed between the plug plate 6 and the first end plate 8, and the second cavity 90 is formed in the bushing seat 9. When the sealing plug 7 does not enter the second cavity 90, the first cavity 80 and the second cavity 90 are in a state of communication. When the sealing plug 7 enters the second cavity 90, the first cavity 80 and the second cavity 90 are in a state of non-communication. Since the aperture of the first through-hole 801 is less than the aperture of the second through-hole 901, the exhaust speed of the first through-hole 801 and the second through-hole 901 is also different. Since the first cavity 80 and the second cavity 90 are divided, the first cavity 80 and the second cavity 90 can be used for exhaust. Therefore, in the device, the first cavity 80 and the second cavity 90 are used for exhaust. The first cavity 80 enters and exits the gas through the first through-hole 801, and the second cavity 90 enters and exits the gas through the second through-hole 901. The speed of the first cavity 80 entering and exiting the gas is less than the speed of the second cavity 90 entering and exiting the gas. When the executor performs the last position, the exhaust is performed through the first through-hole 801, and the exhaust speed is relatively slow, so that the last position can be buffered.

[0028] When the buffer device works, the first cavity 80 and the second cavity 90 are used for exhaust,

[0029] As shown in the accompanying drawings Figure 1 , the accompanying drawings Figure 2 , and the accompanying drawings Figure 3 , the plug plate 6 is provided with a second sealing ring 10.

[0030] The function of the second sealing ring 10 is to ensure the sealing between the plug plate 6 and the cylinder 4.

[0031] As shown in the accompanying drawings Figure 1 , the accompanying drawings Figure 2 , and the accompanying drawings Figure 3As shown, the sealing plug 7 is provided with a first sealing ring 11.

[0032] The first sealing ring 11 is used to ensure the sealing between the sealing plug 7 and the bushing seat 9.

[0033] As shown in Figs. 1, 2 and 3, the plug plate 6 is parallel to the first end plate 8 and the second end plate 3. Figure 1 Figure 2 As shown in Figs. 1, 2 and 3, the first end plate 8 is parallel to the second end plate 3. Figure 3 As shown in Figs. 1, 2 and 3, the plug plate 6 is parallel to the first end plate 8 and the second end plate 3.

[0034] Figure 1 As shown in Figs. 1, 2 and 3, the first end plate 8 is parallel to the second end plate 3. Figure 2 Figure 3 As shown in Figs. 1, 2 and 3, the plug plate 6 is parallel to the first end plate 8 and the second end plate 3.

[0035] As shown in Figs. 1, 2 and 3, the first end plate 8 is parallel to the second end plate 3. Figure 1 Figure 2 As shown in Figs. 1, 2 and 3, the plug plate 6 is parallel to the first end plate 8 and the second end plate 3. Figure 3 As shown in Figs. 1, 2 and 3, the first end plate 8 is parallel to the second end plate 3.

[0036] Figure 1 As shown in Figs. 1, 2 and 3, the plug plate 6 is parallel to the first end plate 8 and the second end plate 3. Figure 2 Figure 3 As shown in Figs. 1, 2 and 3, the first end plate 8 is parallel to the second end plate 3.

[0037] As shown in Figs. 1, 2 and 3, the plug plate 6 is parallel to the first end plate 8 and the second end plate 3. Figure 1 Figure 2 As shown in Figs. 1, 2 and 3, the first end plate 8 is parallel to the second end plate 3. Figure 3 As shown in Figs. 1, 2 and 3, the plug plate 6 is parallel to the first end plate 8 and the second end plate 3.

[0038] Figure 1 Figure 2 Figure 3 Figure 1 As shown in Figs. 1, 2 and 3, the first end plate 8 is parallel to the second end plate 3.

[0039] First, the first through hole 801 and the second through hole 901 are simultaneously supplied with air, which drives the plug plate 6 to move leftward, and the first cavity 80 and the second cavity 90 are combined into a whole (i.e. connected), and the breathing port on the second end plate 3 is naturally discharged; at this time, the valve is opened.

[0040] Then, the air supply is stopped, the spring in the spring module 1 is reset, which drives the plug plate 6 to move rightward, and the breathing port is naturally supplied with air.

[0041] When the valve is closed to the last 8° or so, the plunger enters the bushing seat 9, and the first cavity 80 and the second cavity 90 become independent and disconnected.

[0042] The compressed air in the second cavity 90 is directly discharged from the second through hole 901, and the compressed air in the first cavity 80 is discharged from the first through hole 801. Since the first cavity 80 has a large space but the first through hole 801 is small, the exhaust speed is low, which slows down the closing action of the plug plate 6, thereby generating a buffering effect.
