[0035] The utility model embodiment discloses a piston clamping tool, see attached Figure 1-5 , the piston clamping tool comprises:

[0036] A fixing member 1, and a movable member 2 movably connected to the fixing member;

[0037] The fixing member 1 is provided with a groove, and one or more through holes 11 are provided at the bottom of the groove. One end of the fixing member 1 away from the opening of the groove is connected to one or more first elastic components 12 located in the through hole 11;

[0038] One end of the movable part 2 is provided with one or more limit rods 21, and the end of the limit rod 21 is provided with a limit block 22, and the other end of the movable part 2 is connected to a driving cylinder;

[0039] A first opening 13 is provided on at least one side of the fixing member 1, and a second opening 23 corresponding to the first opening 13 is provided on the side of the movable member 2. When the movable member 2 is embedded in the groove, the limiting rod 21 passes through the through hole 11 and the first elastic member 12, so that the first opening 13 and the second opening 23 are combined to form at least one piston clamping groove; when the movable member 2 is driven by the driving cylinder to move out of the groove, the limiting block 22 compresses the first elastic member 12 until the piston to be clamped enters the piston clamping groove.

[0040] Specifically, the piston clamping tool is used in the process of transporting the piston of the plastic bottle, and is preferably arranged in the piston transporting equipment; at the initial station, the piston to be clamped is pushed into the piston clamping tool through the cooperation of the driving component (such as a cylinder) in the piston transporting equipment, wherein the movement direction of the piston pushed by the driving component is perpendicular to the movement direction of the piston clamping tool; and then the driving cylinder arranged at one end of the movable part 2 is used to transport the piston clamping tool holding the piston to the piston installation station, such as Figure 1 As shown, at this time, the movable part 2 is embedded in the groove, and the first elastic component 12 is in a natural state; after the piston is installed, the piston clamping tool is returned to the initial position by the driving cylinder, such as Figure 2 As shown, at this time, the movable part 2 is driven by the driving cylinder to move out of the groove, and the first elastic component 21 is in a compressed state, thereby realizing that the piston clamping tool clamps the piston back and forth between the initial position and the piston installation position. In one embodiment of the utility model, the piston clamping tool is only provided with a first opening 13 on one side of the fixed part 1, and a second opening 23 is provided on one side of the movable part 2 corresponding to the first opening 13, thereby forming a piston clamping groove, and the piston transportation equipment is provided with a driving component to achieve the clamping of a single piston; in another embodiment of the utility model, the piston clamping tool is provided with a first opening 13 on both sides of the fixed part 1, and two second openings 23 are correspondingly provided on both sides of the movable part 2, thereby forming two piston clamping grooves, and the piston transportation equipment is provided with two driving devices to achieve the clamping of two pistons. Further, the first elastic component 12 is a spring.

[0041] Preferably, both sides of the fixing part 1 are provided with fixing blocks 14, and the fixing blocks 14 are vertically connected to the sides of the fixing part 1. When the driving cylinder drives the movable part 2 to move out of the groove, the fixing blocks 14 are blocked by the baffle 3 on which the piston clamping tool equipment is installed, thereby limiting the displacement of the fixing part 1.

[0042] Specifically, the installed piston clamping tool equipment is a piston transport equipment, which is provided with a baffle 3, which is used to fix the fixing part 1. When the driving cylinder drives the piston clamping tool to return to the initial position, the fixing block 14 is clamped by the baffle 3, so that the fixing part 1 no longer moves; the driving cylinder continues to drive the movable part 2 to move, so that the limit block 22 compresses the first elastic part 12 until a piston clamping groove is formed into which the clamped piston can enter; further, the fixing block 14 can be set to a rectangular structure, and the thickness of the fixing block 14 is consistent with the thickness of the fixing part 1.

[0043] Preferably, the side of the fixing block 14 facing the baffle 3 is connected to a second elastic component 141, which is used to buffer the impact between the fixing block 14 and the baffle 3 and provide a certain degree of elastic space. The second elastic component 141 can be a spring, an elastic pad or a combination of a spring and an elastic pad.

[0044] In one embodiment of the utility model, the piston clamping tool is provided with two piston clamping grooves. When the piston clamping tool clamps two pistons of different sizes, the two fixing blocks 14 are not at the same height in the radial direction, and the fixing block 14 on the side where the relatively smaller piston is located is axially closer to the first opening 13 than the fixing block 14 on the side where the relatively larger piston is located; that is, the position at which the fixing block 14 is arranged is related to the size of the piston. The smaller the piston, the closer the axial position of the fixing block is to the first opening 13; accordingly, the two baffles 3 arranged in cooperation with the piston holding tool are not at the same height in the radial direction, and the baffles on the side of the relatively smaller piston are closer to the first opening 13. The plate 3 is axially closer to the driving cylinder than the baffle plate 3 on the side of the relatively large piston; in addition, the second elastic component 141 on the side of the relatively large piston is a spring and a first elastic pad connected to the spring, and the spring is connected to the fixing block 14, and the second elastic component 141 on the side of the relatively small piston is a second elastic pad, that is, the setting type of the second elastic component 141 is also related to the size of the piston. The larger the piston, the larger the elastic space required. Therefore, the second elastic component 141 on the side of the larger piston is provided with a spring on the basis of the first elastic pad to increase the elastic displacement of the fixing member 1 in the limited state, so as to ensure that the piston smoothly enters the piston clamping groove. It should be noted that the spring connected to the first elastic pad is not marked in the attached figure.

[0045] In another embodiment of the present invention, when the piston clamping tool clamps two pistons of the same size, the two fixing blocks 14 are at the same height in the radial direction; the type of the second elastic component 141 can be selected according to the size of the piston, and this embodiment is not limited to this.

[0046] Preferably, the fixing member 1 is provided with first openings 13 on both sides, and the movable member 2 is provided with two second openings 23 corresponding to the first openings 13, so as to form two piston clamping grooves. Specifically, the size and shape of the first openings 13 on both sides of the fixing member 1 can be the same or different. Similarly, the size and shape of the two second openings 23 of the movable member 2 can be the same or different, thereby forming two same or different piston clamping grooves to meet the needs of different working conditions. Figure 6 An embodiment of the utility model provides a piston clamping tool, which includes two piston clamping grooves of the same size and shape.

[0047] Preferably, the first opening 13 and the second opening 23 are both arc-shaped, and the first opening 13 and the second opening 23 are combined to form a circular piston clamping groove; further, the first opening 13 includes a first arc surface 131 and a first chamfer 132, the first arc surface 131 is a quarter arc surface opening outward, and the first chamfer 132 is provided at the connection between the first arc surface 131 and the side surface of the fixing member 1, and the second opening 23 includes the second arc surface 231, a straight line An extension surface 232, a second chamfer 233 and a third chamfer 234, the second arc surface 231 is a semicircular arc surface opening outward, the straight extension surface 232 is tangent to the second arc surface 231, and is connected to an end of the second arc surface 231 away from the first arc surface 131, the second chamfer 233 is arranged at the connection between the straight extension surface 232 and the side surface of the movable part 2, and the third chamfer 234 is arranged at the connection between the second arc surface 231 and the side surface of the movable part 2.

[0048] Preferably, the movable part 2 is provided with a working groove 24 with a hollow structure at one end close to the driving cylinder, which is convenient for holding the piston clamping tool and installing it on the piston transportation equipment, and is also beneficial for the installation and fixation of the driving cylinder. The end surface of the working groove 24 connected to the driving cylinder is provided with one or more mounting holes 241, and the movable part 2 is fixedly connected to the driving cylinder through the mounting holes by bolts or other fixing parts; further, the working groove 24 is set to one or two, and the mounting holes 241 are provided with two.

[0049] Preferably, the through hole 11, the first elastic component 12 and the limiting rod 21 are all provided in two, which reduces the cost and simplifies the structure, and ensures that when the movable part 2 is driven by the driving cylinder to return to its original position, the fixed part 1 is evenly stressed to avoid the problem of deflection.

[0050] Preferably, the fixing member 1 comprises a first splicing member 151 and a second splicing member 152 which are connected to each other. The first splicing member 151 and the second splicing member 152 are spliced ​​to form the groove. Since the end of the movable member 2 can be embedded in the groove, the fixing member 1 is formed by splicing two parts for easy installation. The first splicing member 151 (or the second splicing member 152) can be installed first, then the movable member 2 is arranged, and finally the second splicing member 152 (or the first splicing member 151) is installed in this order to ensure that the groove of the fixing member 1 matches the end of the movable member 2.

[0051] It should be noted that the embodiments of the present invention have better practicability and do not impose any form of limitation on the present invention. Any technician familiar with the field may use the technical content disclosed above to change or modify it into an equivalent effective embodiment. However, any modification or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
