AI Technical Summary
Due to the gaps in the front and rear connecting parts of traditional cylinders, there are gaps in processing and assembly factors, which lead to wear and impact under high-frequency action, resulting in larger aperture or thinner pin diameter, increasing the empty stroke of the cylinder and affecting the accuracy of the fork action.
Using a cylinder connection structure including a first adjustable joint and a second adjustable joint, the clamping pin shaft is locked to prevent impact wear by installing a plurality of screws for adjusting the degree of clamping and a pin shaft that penetrates the mounting on these joints.
It effectively prevents impact wear caused by high-frequency action of the pin shaft, avoids the problem of larger pin hole diameter or thinner pin diameter, maintains the stability of the empty stroke of the cylinder, and ensures the accuracy of the fork movement.

Abstract
Description
Technical Field
[0001] The utility model relates to a connection structure, in particular to a cylinder connection structure, belonging to the technical field of cylinder connection. Background Technique
[0002] The fork cylinder used on the pipe sticking machine drives the fork to pick up the straws transported by the rotary drum one by one and press them accurately onto the two glue dots ejected in the previous process on the surface of the Tetra Pak box to complete the sticking of the straws. For the fork cylinder, the main test comes from the wear and impact between the front and rear moving connection parts caused by the high-frequency action of the fork cylinder. For the traditional front and rear connection parts of the cylinder, most of them drill holes in the joint or the tailstock and insert the pin shaft. Then there will inevitably be a gap between the pin shaft and the hole due to processing and assembly factors. And this gap will cause wear quickly due to the back-and-forth impact under the high-frequency reciprocating motion. The result is either that the hole diameter becomes larger due to friction and impact, or the diameter of the contact part between the pin shaft and the hole becomes thinner, resulting in an increase in the idle stroke of the cylinder and the fork not moving in place. In view of the above problems, the utility model proposes a new solution. Content of the Utility Model
[0003] The main purpose of the utility model is to solve the deficiencies of the prior art and provide a cylinder connection structure.
[0004] The purpose of the utility model can be achieved by adopting the following technical solutions:
[0005] A cylinder connection structure includes a cylinder, and a first adjustable joint and a second adjustable joint are respectively installed at both ends of the cylinder. A plurality of screws for adjusting the clamping degree are installed on both the first adjustable joint and the second adjustable joint, and a pin shaft is installed through both the first adjustable joint and the second adjustable joint.
[0006] Furthermore, both the first adjustable joint and the second adjustable joint include a connection seat.
[0007] Furthermore, a U-shaped first clamping plate and a second clamping plate are symmetrically arranged on the connection seat, and one end of the first clamping plate and the second clamping plate is connected to the connection seat.
[0008] Furthermore, pin holes matching with the pin shaft are respectively formed through the first clamping plate and the second clamping plate.
[0009] Furthermore, screw holes matching with the screws are respectively formed on the first clamping plate and the second clamping plate, and the pin holes and the screw holes are perpendicular to each other.
[0010] Advantageous technical effects of the present utility model: According to the cylinder connection structure of the present utility model, through the settings of the first adjustable joint, the second adjustable joint and the screw, the pin shaft penetrating and installed on the first adjustable joint and the second adjustable joint can be locked and clamped by tightening the screw, so that the pin shaft and the first adjustable joint or the second adjustable joint become an integrally and tightly fitted body, thereby preventing the front and back movement of the pin shaft caused by the high-frequency movement of the cylinder, resulting in impact wear. At the same time, it also avoids the problem that the pin hole becomes larger in diameter due to friction and impact, or the diameter of the contact part between the pin shaft and the pin hole becomes thinner, resulting in an increase in the empty stroke of the cylinder and the fork movement not in place.

[0015] To make the technical solutions of the present utility model clearer and more definite to those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings, but the embodiments of the present utility model are not limited thereto.
[0016] As Figures 1 - 3As shown in the figure, the cylinder connection structure provided in this embodiment includes a cylinder 1. First adjustable joints 2 and second adjustable joints 3 are respectively installed at both ends of the cylinder 1. A plurality of screws 5 for adjusting their clamping degree are installed on both the first adjustable joint 2 and the second adjustable joint 3. A pin shaft 4 is installed through both the first adjustable joint 2 and the second adjustable joint 3. Through the settings of the first adjustable joint 2, the second adjustable joint 3 and the screw 5, the pin shaft 4 installed through the first adjustable joint 2 and the second adjustable joint 3 can be locked and clamped by tightening the screw 5, so that the pin shaft 4 and the first adjustable joint 2 or the second adjustable joint 3 become an integrally and tightly matched body, thereby preventing the front and back movement of the pin shaft 4 caused by the high-frequency movement of the cylinder 1, resulting in impact wear. At the same time, it also avoids the problem that the pin hole 104 becomes larger in diameter due to friction and impact, or the diameter of the contact part between the pin shaft 4 and the pin hole 104 becomes thinner, resulting in an increase in the dead stroke of the cylinder 1 and the fork movement not being in place.
[0017] Both the first adjustable joint 2 and the second adjustable joint 3 include a connection seat 101. U-shaped first clamping plates 102 and second clamping plates 103 are symmetrically arranged on the connection seat 101. One ends of the first clamping plate 102 and the second clamping plate 103 are connected to the connection seat 101. Through the setting of the connection seat 101, the installation of the first clamping plate 102 and the second clamping plate 103 can be facilitated.
[0018] Pin holes 104 that cooperate with the pin shaft 4 are respectively formed through both the first clamping plate 102 and the second clamping plate 103. Through the setting of the pin holes 104, the pin shaft 4 can pass through the first clamping plate 102 and the second clamping plate 103 conveniently.
[0019] Screw holes 105 that cooperate with the screws 5 are respectively formed in both the first clamping plate 102 and the second clamping plate 103. The pin holes 104 and the screw holes 105 are perpendicular to each other. Through the setting of the screw holes 105, it is convenient to cooperate with the screws 5 during use. When the screws 5 are screwed into the screw holes 105 during use, the opening degree of the U-shaped first clamping plate 102 and the second clamping plate 103 can be adjusted, so as to adjust the clamping degree of the pin shaft 4 in the pin hole 104.
[0020] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent replacements or changes, all belong to the protection scope of the present invention.
