detailed description

The structures, proportions, sizes, etc. shown in the accompanying drawings of the description are only used to cooperate with the content disclosed in the description, for those who are familiar with this technology to understand and read, and are not used to limit the limited conditions that the utility model can be implemented, so It has no technical substantive meaning, and any modification of structure, change of proportional relationship or adjustment of size shall still fall within the scope of the disclosure of this utility model without affecting the functions and objectives of this utility model. within the range covered by the technical content. At the same time, terms such as "upper", "lower", "front", "rear", and "middle" quoted in this specification are only for the convenience of description, and are not used to limit the practicable scope of the present utility model. The change or adjustment of the relative relationship between the range and the technical content shall also be regarded as the implementable scope of the present utility model without substantive changes in the technical content.

As shown in Figures 1-3, the utility model is a cylinder clamping device, which includes a bottom plate 1, on which two uprights 21, 22 are arranged, between which two uprights 21, 22 are connected The beam 3 is detachably connected to the two columns 21 and 22. The crossbeam 3 is pierced with a vertical screw rod 31, the screw rod 31 is screwed with the crossbeam 3, the bottom end of the screw rod 31 is provided with a briquetting block 4, and the bottom surface of the briquetting block 4 is provided with multiple 41 presser feet. Because the presser foot 41 protrudes from the pressing block 4, it can also effectively play a pressing role when the top surface of the cylinder body is uneven. When the screw rod 31 rotates relative to the beam 3, the pressing block 4 moves up and down. The bottom plate 1 is provided with a plurality of positioning pins 11 and a plurality of support bodies 12, the top surface of the support body 12 is a plane, and the positioning pins 11 are used for positioning with the process holes on the cylinder body, and the support bodies 12 plays a supporting role to the cylinder body part, and keeps the cylinder body in a stable state when it is clamped. One side of the top surface of the bottom plate is provided with at least one limiting plate 13, through which the clamping position of the cylinder body can be preliminarily determined, which brings convenience to the operation of the staff and improves work efficiency.

In this embodiment, with reference to Fig. 1 and Fig. 2, an auxiliary plate 5 that can rotate in the horizontal direction is provided at both ends of the pressing block 4, and a plurality of presser feet 41 are respectively provided on the bottom surface of the auxiliary plate 5. . The auxiliary plate 5 can facilitate the adjustment of the position of the presser foot 41, improve the flexibility of use, and better compress the cylinder body. Further, the presser feet 41 are connected to the auxiliary plate 5 through screws, that is, the heights of the presser feet 41 are all adjustable.

In this embodiment, in order to facilitate the rotation of the screw rod 31 , a rotating rod 32 is fixed on the upper end of the screw rod 31 , and the rotating rod 32 is perpendicular to the screw rod 31 . In other embodiments, the end of the screw 31 can be designed to have a non-circular cross-section, and the screw 31 can be rotated by an auxiliary tool such as a wrench.

In order to facilitate the taking and placing of the cylinder body during use, as shown in Figures 1 and 2, one end of the crossbeam 3 is hinged to a column 21, and the other end of the crossbeam 3 is provided with a hook 33, which can be hooked on another On a column 22. When the cylinder body needs to be clamped, first turn the crossbeam 3 to other positions, let the cylinder body be put down directly from the top of the device, and then turn the crossbeam 3 so that the hook 33 is connected with the column 22. Specifically, bolts and other parts can be used to connect with the cylinder body. The column 22 cooperates to compress the hook 33 on the column 22 to ensure the working position.

In this embodiment, the bottom plate 1 is provided with a spacer 6 , and the positioning pin 11 and the support body 12 are both installed on the spacer 6 . The spacer 6 can be provided with a plurality of positioning holes and other structures, and then the positioning pins 11 and the support body 12 can be installed in different positions according to actual usage needs. The positions of the positioning pin 11 and the support body 12 in the present invention are determined according to actual needs. In this embodiment, as shown in FIG. 3 , two pads 6 are arranged relatively parallel, and positioning pins 11 and support bodies 12 are respectively provided on the two pads 6 .

Combined with Figure 1-Figure 4, when the device is in use, turn the rotating rod 32 so that the presser foot 41 is at a high position, and then turn the crossbeam 3 to let the cylinder 7 be put in from above, and put one side of the cylinder 7 against the limit plate 13 to preliminarily define the position, and then fine-tune the position of the cylinder 7 to allow the positioning pin 11 to be inserted into the process hole of the cylinder 7, and at the same time allow the support body 12 to effectively support the part of the cylinder 7 for final positioning. After the position of the cylinder block 7 is determined, turn the beam 3 again to allow the hook 33 to be connected with the column 22, and turn the rotating rod 32 after confirming that it is correct. Along with the rotation of rotating rod 32, presser foot 41 can be pressed against on the cylinder block 7, and simultaneously the worker adjusts the position of presser foot 41 at any time to allow a plurality of presser feet 41 to carry out effective contact with cylinder body 7 top surface, and the presser foot 41 The position can also be adjusted in height at any time as needed. Because the thread fit itself has a self-locking effect, when the presser foot 41 effectively presses the cylinder 7, the cylinder 7 is clamped on the device, so that subsequent processing can be performed. After the corresponding processing is completed, the cylinder body 7 is removed from the device according to the reverse operation of the above steps.

In summary, the utility model is a clamping device for a cylinder body, which can solve the problem of low work efficiency of clamping the cylinder body. Therefore, the utility model effectively overcomes some practical problems in the prior art and thus has high utilization value and use significance.
