Technical field
The invention belongs to Pneumatic Transmission apparatus field, be specifically related to a kind of back springing type air cylinder.
Background technique
In existing Pneumatic Transmission equipment, air cylinder is common power transmitting apparatus, mainly comprise cylinder body, piston rod and piston, piston is driven by the to-and-fro motion of piston rod, thus transferring power, existing air cylinder, the power transmitted continuous print often, but for the processing (such as: the surface Machining of intermittence) of some special process, required transmission of power has gap and regular transmission, just can reach the processing request required for us, in order to the special processing request of meeting a cassation, owing to lacking suitable power transmitting apparatus, people adopt the processing having carried out special process by hand usually, but work in-process, efficiency is low is apparent, and for the regular manufacturing procedure of some complexity, when amount of finish is larger, manual operations often can make mistakes, great difficulty is brought to machinery production.
Summary of the invention
What the present invention solved is need intermittent surface Machining for some, adopts manual operations, cause its efficiency low and the problem of often makeing mistakes owing to lacking suitable power transmitting apparatus.
In order to solve the problems of the technologies described above, the invention provides following technological scheme: a kind of back springing type air cylinder, comprise cylinder body and piston rod, cylinder body comprises earthen pipe, cylinder cap and cylinder head, cylinder head is run through in one end of piston rod, piston is provided with in earthen pipe, helical spring and rubber cushion cover is also provided with in described earthen pipe, rubber cushion cover is the annular ring of hollow, internal diameter size and the helical spring external diameter size of cushion collar match, cushion collar is embedded in piston, and helical spring is connected with cushion collar and the piston rod running through cylinder head respectively.
In this programme, air enters in earthen pipe, the state of high pressure is formed in earthen pipe, promote piston advances forward, cylinder head is run through in one end of piston rod, helical spring is connected with cushion collar and the piston rod running through cylinder head respectively, cushion collar is embedded in piston, make piston, helical spring moves together with piston rod, piston rod drives piston energy reciprocating, piston is under helical spring drive, can automatically reply, because spring is flexible member, and piston is embedded with cushion collar, when being returned to initial position, there is the more stable resilience time, a period of time can be cushioned when upper once piston advances forward, thus the transmission of intermittent motion can be realized.
Further, be provided with a chamber in described piston, chamber is provided with the open channel towards piston rod, and piston rod is provided with round table-like dop, and the large footpath of dop is greater than the diameter of piston rod, and dop is located in chamber, and open channel passes through for piston rod only.Piston rod is reciprocating, because piston rod is provided with round table-like dop, dop also moves reciprocatingly along piston rod, and drive piston to move together, owing to being provided with towards the open channel of piston rod in piston, and open channel passes through for piston rod only, dop is made not depart from piston when chamber indoor moving, when piston rod does return motion, dop in chamber first can move to the notch place of chamber with piston rod, piston is drawn close to the dop at chamber notch place gradually under the effect of air-flow, extend the resilience time of piston, thus make the passing time of intermittent motion longer.
Further, described helical spring is columniform rectangular cross-section Compress Spring, spring absorb energy many, manufacturability and fatigability good.
Further, described helical spring one end is embedded in cushion collar, and both being linked and packed is simple.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of back springing type air cylinder of the present invention embodiment 1;
Fig. 2 is the schematic diagram of a kind of back springing type air cylinder of the present invention embodiment 2.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Embodiment 1
As shown in Figure 1, a kind of back springing type air cylinder, comprise cylinder body and piston rod 3, cylinder body comprises earthen pipe 1, cylinder cap 2 and cylinder head 3, cylinder head 2 is run through in one end of piston rod 3, piston 4 is provided with in earthen pipe 1, helical spring 5 and rubber cushion cover is also provided with in earthen pipe 1, rubber cushion cover is the annular ring of hollow, the internal diameter size of cushion collar and the external diameter size of helical spring 5 match, cushion collar is embedded in piston 4, helical spring 5 is connected with cushion collar and the piston rod 3 running through cylinder head respectively, helical spring 5 is columniform rectangular cross-section Compress Spring, one end of helical spring 5 is embedded in cushion collar.
In the present embodiment, air enters in earthen pipe 1, the state of high pressure is formed in earthen pipe 1, promote piston 4 to travel forward, cylinder head 2 is run through in one end of piston rod 3, helical spring 5 is connected with cushion collar and the piston rod 3 running through cylinder head respectively, cushion collar is embedded in piston 4, make piston 4, helical spring 5 moves together with piston rod 3, piston rod 3 drives piston 4 energy reciprocating, piston 4 is under the drive of helical spring 5, can automatically reply, because helical spring 5 is flexible member, and piston 4 is embedded with cushion collar, when being returned to initial position, there is the more stable resilience time, a period of time can be cushioned when upper once piston 4 travels forward, thus the transmission of intermittent motion can be realized.In addition, helical spring 5 is columniform rectangular cross-section Compress Spring, and the energy that spring absorbs is many, and manufacturability and fatigability are good, and one end of helical spring 5 is embedded in cushion collar, and both are linked and packed simply.
Embodiment 2
As shown in Figure 2, a kind of back springing type air cylinder described in the present embodiment, its structure is substantially the same manner as Example 1, difference is: be provided with a chamber 10 in piston 4, chamber 10 is provided with the open channel towards piston rod 3, and piston rod 3 is provided with round table-like dop 11, and the large footpath of dop 11 is greater than the diameter of piston rod 3, dop 11 is located in chamber 10, and open channel passes through for piston rod 3 only.
The principle of said structure is such: piston rod 3 is reciprocating, because piston rod 3 is provided with round table-like dop 11, dop 11 also moves reciprocatingly along piston rod 3, and drive piston 4 to move together, owing to being provided with towards the open channel of piston rod 3 in piston 4, and open channel passes through for piston rod 3 only, piston 4 is not departed from when making dop 11 mobile in chamber 10, when piston rod 3 does return motion, dop 11 in chamber 10 first can move to the notch place of chamber 10 with piston rod 3, piston 4 is drawn close to the dop 11 at chamber 10 notch place gradually under the effect of air-flow, extend the resilience time of piston 4, thus make the passing time of intermittent motion longer.
