Description

Technical Field

[0001] The utility model relates to the technical field of band sawing equipment, in particular to a centering clamping device for a band sawing machine. Background Art

[0002] At present, in the band saw cutting industry, the cutting of round bars and round tubes mostly uses hydraulic clamping vises to clamp and position the workpieces. Usually, there is a fixed vise (or micro-motion vise) on the right and a movable vise on the left. The movable vise moves the bar / tube workpiece radially toward the fixed vise to achieve clamping and positioning of the workpiece, and then the rotating band saw blade cuts the workpiece as the work feed progresses.

[0003] However, for long bars / tubes, this clamping method often causes misalignment due to the length of the bars / tubes. Generally, the bars / tubes must be swung manually several times to make the tail straight for normal clamping. This is especially inconvenient when replacing bars / tubes of different diameters. In addition, bars / tubes transmitted from the production line are generally transmitted through V-shaped rollers for automatic centering and cannot be directly connected to the sawing machine, which is inconvenient to operate. Utility Model Content

[0004] The utility model aims to provide a centering and clamping device for a band sawing machine, which can realize the conveying and clamping and positioning of long materials, and solve the problems existing in the prior art that the centering and clamping of workpieces cannot be realized and the workpieces outputted from the production line cannot be directly docked.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a centering clamping device for a band saw, comprising:

[0006] matrix;

[0007] A left vise, which is arranged on one side of the base body;

[0008] a right vise, which is disposed on the other side of the base body;

[0009] A gear assembly, wherein one side of the gear assembly is provided with a left rack connected to the bottom of the left vise, and the other side of the gear assembly is provided with a right rack connected to the bottom of the right vise;

[0010] The power assembly is arranged on the outside of the base body and connected with the left vise.

[0011] Furthermore, a left sliding block located in the base body is provided below the left vise, and the middle part of the outer side of the left sliding block is connected to the power assembly.

[0012] Further, the left rack is located at one side below the left sliding block.

[0013] Furthermore, a right slider located in the base is provided below the right vise, and a right rack is provided on one side below the right slider.

[0014] Furthermore, guide rails corresponding to the left slider and the right slider are arranged in the base body.

[0015] Furthermore, the structures of the left and right vises are symmetrical, the inner sides of which are vertical structures, and both are L-shaped structures.

[0016] Further, the central axis of the gear assembly is connected to the base.

[0017] According to an embodiment of the present disclosure, the power assembly is a hydraulic cylinder.

[0018] The centering clamping device of the band sawing machine of the utility model realizes the centering and synchronous clamping of the workpiece by the left vise and the right vise through the transmission of the gear assembly and the left rack and the right rack. The power assembly is installed on the left side of the base body, and the piston rod of the power assembly is connected to the left slider under the left vise. When the piston rod moves to the right, the left slider is pushed to move to the right. The left vise is connected and installed above the left slider, and the left end of the left rack is connected and installed in front of it. The left vise and the left rack move to the right together with the left slider. At this time, the left rack drives the gear assembly to rotate, and the transmission gear of the gear assembly drives the right rack to move to the left in the opposite direction. Since the gear rack transmission is synchronous, the centering strokes of the left rack and the right rack are consistent, that is, they move synchronously symmetrically with respect to the center line. The right end of the right rack is connected and installed behind the right slider, and the right vise is connected and installed on the right slider. In this way, when the right rack moves to the left, the right vise is simultaneously driven to move to the left through the right slider.

[0019] In summary, the centering clamping device of the band sawing machine of the utility model is pushed by the power assembly to clamp to the right, and the left and right vises realize centering synchronous movement to clamp the workpiece. Conversely, when the power assembly is pulled to the left to release, the left and right vises realize centering synchronous movement to release the workpiece. Regardless of clamping or releasing the workpiece, the positioning center of the workpiece is always unchanged, and the workpiece output by the production line can be directly connected to realize the conveying and clamping positioning of long materials.

The left vise 2 and the right vise 5 are symmetrical in structure, and the inner side thereof is a vertical structure to clamp the surface of the workpiece. The cross-sections of the left vise 2 and the right vise 5 are both L-shaped structures, and the structural design is reasonable to ensure stable clamping of the workpiece.

[0028] Among them, in this embodiment, a left slider 3 located in the base 1 is provided below the left vise 2. Preferably, the left vise 2 is connected to the left slider 3 by bolts to ensure the stability of the movement of the two. The middle part of the outer side of the left slider 3 is connected to the power assembly 9, and the power assembly 9 is arranged on the outer side of the base 1. Preferably, the power assembly 9 is a hydraulic cylinder. Driven by the power assembly 9, the left slider 3 moves, and the left vise 2 moves accordingly.
