Description

Technical Field

[0001] The utility model relates to the field of sawing equipment, in particular to a clamp positioning device for a multi-segment saw. 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

[0004] The purpose of the utility model is to provide a clamp positioning device for a multi-segment saw.

[0005] The technical solution for achieving the purpose of the utility model is: a clamp positioning device for a multi-segment saw, comprising a first clamp connecting member fixedly connected to the clamp of the multi-segment saw, a frame connecting rod fixedly connected to the frame of the multi-segment saw, and a second clamp connecting member located on a side of the frame connecting rod away from the first clamp connecting member;

[0006] The second clamp connector remains stationary relative to the multi-segment saw clamp;

[0007] A telescopic mechanism is installed on one of the first clamp connecting member and the second clamp connecting member, and a first through hole for a telescopic rod of the telescopic mechanism to freely pass through is provided on the other clamp connecting member;

[0008] The frame connecting rod is also provided with a second through hole for the telescopic rod to pass freely;

[0009] The telescopic rod passes through the second through hole and the first through hole in sequence and is provided with an end stopper at its end, and the end stopper cannot pass through the first through hole;

[0010] The clamp positioning device further comprises a spring, wherein the spring compression limit is located between the other clamp connecting member and the frame connecting rod, and one end of the spring close to the frame connecting rod is fixedly connected to the telescopic rod.

[0011] The clamp positioning device for a multi-segment saw of the present invention comprises a device wherein when the telescopic rod of the telescopic mechanism is retracted inward, the telescopic rod drives the spring and the end stop to move toward the frame connecting rod, the spring being always in a compressed state. When the spring contacts the frame connecting rod, the contraction force of the telescopic rod and / or the elastic force of the spring causes the ends of the spring to be respectively pressed and fixed to the frame connecting rod and the other clamp connecting member, thereby achieving positioning of the multi-segment saw clamp. When the telescopic rod of the telescopic mechanism is extended outward, the telescopic rod drives the spring to move away from the frame connecting rod, separating the spring from the frame connecting rod and releasing the multi-segment saw clamp. Furthermore, when the spring is pressed against the frame connecting rod to achieve positioning of the multi-segment saw clamp, even if the air supply of the telescopic mechanism fails (ie, insufficient air supply), the elastic force of the spring can still press the ends of the spring against the frame connecting rod and the other clamp connecting member, thereby ensuring the fixation of the multi-segment saw clamp.

[0012] Preferably, the spring is coaxially sleeved on the telescopic rod. Of course, the spring is not limited to being sleeved on the telescopic rod, and it can also be arranged on the side of the telescopic rod.

[0013] Preferably, a gasket is provided at one end of the spring near the frame connecting rod; the gasket is fixedly connected to the telescopic rod and cannot pass through the second through-hole; the spring compression limiter is located between the other clamp connector and the gasket. In this case, the end of the spring near the frame connecting rod can be fixedly connected to the telescopic rod via the gasket. Furthermore, the gasket is annular and coaxially mounted on the telescopic rod. Of course, the clamp positioning device of the multi-segment saw of the present invention can also be equipped with no gasket.

[0014] Preferably, the second clamp connection member can be fixedly connected to the first clamp connection member via a plurality of fixing rods. Furthermore, there can be multiple fixing rods that are evenly distributed around the periphery of the telescopic mechanism.

[0015] Preferably, the second through hole 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.

[0016] The telescopic mechanism can be a pneumatic cylinder or an oil cylinder.

[0017] Preferably, the end stop is a locking nut, and the end stop is threadedly matched with the telescopic rod to achieve a fixed connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Combine Figure 1 and Figure 2 A clamp positioning device for a multi-segment saw includes a first clamp connector 10 fixedly connected to a clamp of the multi-segment saw, a frame connecting rod 20 fixedly connected to a frame of the multi-segment saw, and a second clamp connector 30 located on a side of the frame connecting rod 20 facing away from the first clamp connector 10;

[0022] The second clamp connector 30 remains stationary relative to the multi-segment saw clamp;

[0023] The first clamp connecting member 10 is provided with a telescopic mechanism 40 , and the second clamp connecting member 30 is provided with a first through hole 31 for the telescopic rod 41 of the telescopic mechanism 40 to freely pass through;

[0024] The frame connecting rod 20 is also provided with a second through hole 21 for the telescopic rod to freely pass through;

[0025] The telescopic rod 41 passes through the second through hole 21 and the first through hole in sequence and is provided with an end stopper 50 at its end. The end stopper 50 cannot pass through the first through hole 31.

[0026] The clamp positioning device further includes a spring 60 , which is compressed and located between the second clamp connector 30 and the frame connecting rod 20 , and one end of the spring 60 close to the frame connecting rod 20 is fixedly connected to the telescopic rod 41 .

[0027] like Figure 1 As shown, when the telescopic rod 41 of the telescopic mechanism 40 contracts inwardly, the telescopic rod 41 drives the spring 60 and the end stop 50 to move toward the frame link 20, and the spring 60 is always in a compressed state. When the spring 60 moves to contact the frame link 20, under the action of the contraction force of the telescopic rod 41 and / or the elastic force of the spring 60, the two ends of the spring 60 are respectively pressed and fixed on the frame link 20 and the second clamp connecting member 30, thereby realizing the positioning of the multi-segment saw clamp; Figure 2As shown, when the telescopic rod 41 of the telescopic mechanism 40 is stretched outward, the telescopic rod 41 drives the spring 60 to move away from the frame connecting rod 20, so that the spring 60 is separated from the frame connecting rod 20, and the multi-segment saw clamp is released.

[0028] Of course, the telescopic mechanism 40 may also be mounted on the second clamp connector 30 , and the first clamp connector 10 may be provided with a first through hole for the telescopic rod 41 of the telescopic mechanism 40 to freely pass through.

At this time, the end of the spring 60 near the frame connecting rod 20 can be fixedly connected to the telescopic rod 41 through the gasket 70. Further, as Figure 1 、 Figure 2 As shown, the gasket 70 is an annular structure and is coaxially sleeved on the telescopic rod 41. Of course, the clamp positioning device of the multi-segment saw of the present invention can also be provided with the gasket 70.

[0031] Preferably, Figure 1 、 Figure 2 As shown, the second clamp connection member 30 can be fixedly connected to the first clamp connection member 10 through a plurality of fixing rods 80. Figure 1 、 Figure 2 As shown, there can be multiple fixing rods 80 evenly distributed around the periphery of the telescopic mechanism 40. Of course, the second clamp connector 30 can also be directly fixedly connected to the multi-segment saw clamp, in which case the fixing rod 80 is not required. The number of telescopic mechanisms 40 is not limited to one as shown in the drawings, and its number can be adjusted as needed. The number of fixing rods 80 is also not limited to two as shown in the drawings, and its number can be increased or decreased as needed.

[0032] Preferably, Figure 1 、 Figure 2 As shown, the second 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.

[0033] The telescopic mechanism 40 may be a pneumatic cylinder or an oil cylinder.

[0034] Preferably, Figure 1 、 Figure 2 As shown, the end stop 50 is a locking nut, and the end stop 50 is threadedly engaged with the telescopic rod 41 to achieve a fixed connection.
