Description

Technical Field

[0001] The utility model relates to the field of sawing equipment, in particular to a self-locking fixing device of a multi-segment saw clamp. Background Art

[0002] Long materials, such as bundles of bamboo and wood, require a multi-segment saw to cut and process them into products. The typical structure of an existing multi-segment saw consists of a frame, several clamps, a cutting mechanism, and a control unit. The clamps are mounted on the frame in a horizontally spaced sequence, with the cutting mechanism mounted on one side of the clamps. To operate, the clamps are first adjusted to the desired spacing, then the bundle of bamboo strips is placed horizontally between all the clamps, where they are clamped securely. The control unit then controls the cutting mechanism to move toward the clamps, automatically completing the cutting of the material.

[0003] After the existing multi-segment saw is adjusted and shifted, the clamp is usually fixed by screw locking. However, this fixing method requires manual operation, which is time-consuming and labor-intensive. Utility Model Content

[0006] When a spring is connected between the movable pressure plate and the clamp connecting seat, the spring is in a stretched state, which can provide the movable pressure plate with a pulling force to move in the direction of the clamp connecting seat, so that the movable pressure plate can be pressed and fixed on the frame connecting rod. Since the frame connecting rod is fixedly connected to the multi-segment saw frame, the positioning of the clamp connecting seat and the multi-segment saw clamp is achieved; when a spring is connected between the movable pressure plate and the anti-slip limit member, the spring is in a compressed state, which can provide the movable pressure plate with a thrust to move in the direction of the clamp connecting seat, so that the movable pressure plate can be pressed and fixed on the frame connecting rod, thereby achieving the positioning of the clamp connecting seat and the multi-segment saw clamp.

Furthermore, the telescopic mechanism preferably adopts a cylinder or a hydraulic cylinder. In the specific implementation process, the first through hole is a strip-shaped stroke hole, so that the multi-segment saw clamp can move along the length direction of the strip-shaped stroke hole to adjust its position.

[0016] The following is a detailed description of the best embodiment of the self-locking fixing device of the multi-segment saw clamp of the present invention with reference to the accompanying drawings: Example 1

[0017] like Figure 1 As shown, a self-locking fixing device of a multi-segment saw clamp comprises a clamp connecting seat 10 fixedly connected to the multi-segment saw clamp, a frame connecting rod 20 fixedly connected to the multi-segment saw frame and a movable pressure plate 30 arranged opposite to the clamp connecting seat 10; the movable pressure plate 30 and the clamp connecting seat 10 are respectively arranged on both sides of the frame connecting rod 20; a connecting rod 40 is passed through the movable pressure plate 30, and the end of the connecting rod 40 facing the clamp connecting seat 10 is fixedly connected to the clamp connecting seat 10, and an anti-slip stopper 50 is fixed on the other end of the connecting rod 40; a spring 60 is connected between the movable pressure plate 30 and the anti-slip stopper 50 (or between the movable pressure plate 30 and the clamp connecting seat 10), and the elastic force of the spring 60 is used to realize the compression and fixation between the movable pressure plate 30 and the frame connecting rod 20;

[0018] The clamp connection base 10 is further provided with a telescopic mechanism 70; the telescopic mechanism 70 includes a telescopic rod 71, which is parallel to the connecting rod 40; the frame connecting rod 20 is located on the telescopic path of the telescopic rod 71, and the frame connecting rod 20 is provided with a first through hole 21 for the outer end of the telescopic rod 71 to movably pass through, and the outer end of the telescopic rod 71 is fixedly connected to the movable pressing plate 30;

[0019] Furthermore, there is only one connecting rod 40 and two telescopic mechanisms 70 , and the two telescopic mechanisms 70 are evenly distributed on the periphery of the connecting rod 40 . Example 2

[0020] The self-locking fixing device of the multi-segment saw clamp of embodiment 2 is different only in that: Figure 2 As shown, there is only one telescopic mechanism 70 and two connecting rods 40 , and the two connecting rods 40 are evenly distributed on the periphery of the telescopic mechanism 70 .

[0021] Both Example 1 and Example 2 have a dual positioning structure of the multi-segment saw clamp.

[0022] The first-level multi-segment saw clamp positioning structure is realized by "movable pressure plate 30, connecting rod 40, anti-slip stopper 50 and spring 60", and the working mechanism is: when the spring 6 is connected and arranged between the movable pressure plate 30 and the clamp connecting seat 10, the spring 60 is kept in a stretched state, which can provide the movable pressure plate 30 with a pulling force to move in the direction of the clamp connecting seat 10, so that the movable pressure plate 30 can be pressed and fixed on the frame connecting rod 20, thereby realizing the positioning of the clamp connecting seat 10 and the multi-segment saw clamp; when the spring 60 is connected and arranged between the movable pressure plate 30 and the anti-slip stopper 50, the spring 60 is kept in a compressed state, which can provide the movable pressure plate 30 with a thrust to move in the direction of the clamp connecting seat 10, so that the movable pressure plate 30 can be pressed and fixed on the frame connecting rod 20, thereby realizing the positioning of the clamp connecting seat 10 and the multi-segment saw clamp.

[0023] The second-level multi-segment saw clamp positioning structure is realized by a telescopic mechanism, and the working mechanism is: when the telescopic rod of the telescopic mechanism 70 is contracted, it can drive the movable pressure plate 30 to move toward the clamp connecting seat 10, and press the movable pressure plate 30 and the frame connecting rod 20 together, thereby realizing the positioning of the clamp connecting seat 10 and the multi-segment saw clamp; when the telescopic rod 71 is stretched, it can drive the movable pressure plate 30 to move away from the clamp connecting seat 10, so that the movable pressure plate 30 is separated from the frame connecting rod 20, and the position of the clamp connecting seat 10 and the multi-segment saw clamp can be freely adjusted.

[0024] Of course, the self-locking fixture of the multi-segment saw clamp can also achieve positioning of the multi-segment saw clamp solely by means of the "movable pressure plate 30, connecting rod 40, anti-slip stopper 50, and spring 60"; in this case, the telescopic mechanism 70 can be omitted. However, it is preferred that the "movable pressure plate 30, connecting rod 40, anti-slip stopper 50, and spring 60" and the telescopic mechanism 70 are provided simultaneously.

[0025] The numbers of the telescopic mechanisms 70 and the connecting rods 40 are not limited to the specific numbers shown in the drawings, and they can be adjusted as needed.

[0026] The self-locking fixing devices of the multi-segment saw clamps of Example 1 and Example 2 can be improved as follows:

[0027] (1) If Figure 1 、 Figure 2 As shown, the telescopic mechanism 70 preferably adopts a pneumatic cylinder or a hydraulic cylinder.

[0028] (2) If Figure 1 、 Figure 2 As shown, the first through hole 21 is a strip-shaped travel hole, so that the multi-segment saw clamp can move along the length direction of the strip-shaped travel hole to adjust its position.

[0029] (3) If Figure 1 、 Figure 2 As shown, the anti-slip block 50 is a locking nut, and the anti-slip block 50 is threadedly engaged with the connecting rod 40 to achieve a fixed connection. Of course, the anti-slip block 50 can be but is not limited to a locking nut, and the anti-slip block and the connecting rod 40 can be fixedly connected in any form.

[0030] (4) If Figure 1 、 Figure 2 As shown, the movable pressure plate 30 is provided with a second through hole for the outer end of the telescopic rod 71 to movably pass through, and the telescopic rod 71 is provided with a first limiting nut 711 and a second limiting nut 712 at both ends of the second through hole. The first limiting nut 711 and the second limiting nut 712 are respectively threadedly engaged with the telescopic rod 71, thereby pressing and fixing the movable pressure plate 30 between the first limiting nut 711 and the second limiting nut 712, thereby achieving a fixed connection between the movable pressure plate 30 and the telescopic rod 71. Of course, the movable pressure plate 30 and the connecting rod 40 can be fixed in any form.

[0031] (5) A washer 80 is sleeved on the telescopic rod 71 on the side of the movable pressing plate 30 facing the frame connecting rod 20. Of course, the washer 80 can also be omitted in the present invention.

[0032] (6) If Figure 1 、 Figure 2 As shown, the spring 60 is coaxially sleeved on the connecting rod 40. Of course, the spring 60 can also be arranged on the side of the connecting rod 40.
