Technical Field

[0001] This utility model belongs to the field of electrolytic aluminum production technology, and specifically relates to a vertical band saw clamping device. Background Technology

[0002] When performing high and low jaw sawing operations on anode guide rods, a vertical band saw must be used for auxiliary production. During the clamping and tightening process, the vertical band saw uses a fixed-point clamping method for the clamping jaws. When sawing larger workpieces, the lifting point of the load is exactly at the clamping jaw cylinder, and the hook of the overhead crane is prone to colliding with the cylinder, causing damage to the cylinder. Utility Model Content

[0003] The purpose of this utility model is to provide a clamping device for a vertical band saw, which aims to solve the problem in the above-mentioned background art where the hook of the overhead crane collides with the cylinder container, causing damage to the cylinder.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A clamping device for a vertical band saw includes a vertical band saw with a main frame and a cutting assembly. The main frame is equipped with a clamping mechanism, which includes a support column and a fixed column arranged parallel to each other on the main frame. The top of the support column is provided with a crossbeam rotatably connected to it. A cylinder is provided vertically along the crossbeam. The piston rod of the cylinder passes through the crossbeam, and the end of the piston rod is provided with a pressure head. One end of the crossbeam is detachably connected to the fixed column.

[0006] Furthermore, the end of the crossbeam is provided with a limiting groove, the top of the fixed column is provided with a groove and a limiting mechanism, the limiting mechanism includes a limiting rod for passing through the limiting groove, a pressure plate and a threaded sleeve, one end of the limiting rod passes through the groove and is hinged to the groove, the upper part of the limiting rod is provided with a threaded part, the threaded sleeve is sleeved on the limiting rod and threadedly connected to the threaded part, and the pressure plate is slidably sleeved on the limiting rod between the threaded sleeve and the fixed column.

[0007] The limiting rod rotates vertically into the limiting groove, and the threaded sleeve is rotated by the hand lever, thereby pressing the pressure plate against the crossbeam.

[0008] Furthermore, the bottom of the pressure head is provided with a clamping component, which includes a support rod and a pressure foot. The support rod is located below the crossbeam and parallel to the crossbeam. The pressure foot is located at the bottom of the support rod, and multiple pressure feet are arranged at intervals along the length of the support rod.

[0009] Furthermore, the support rod has an elongated groove at its bottom, and the pressure foot includes a positioning sleeve, as well as a pressure block, a screw, and a slider connected in sequence. The slider is slidably connected to the elongated groove, and the positioning sleeve is fitted on the outside of the screw and threadedly engaged with the screw. The top of the positioning sleeve has an inverted conical structure, and the positioning sleeve adjusts and fixes the position of the pressure foot.

[0010] Compared with the shortcomings and deficiencies of the prior art, the present invention has the following beneficial effects.

[0011] 1. This utility model provides a clamping device for a vertical band saw. The support column, fixed column and crossbeam are combined into a gate-shaped structure to form a stable support. The cylinder is set on the crossbeam. The cylinder drives the piston rod to move the pressure head to clamp the workpiece. One end of the crossbeam is rotatably connected to the support column, and the other end is detachably connected to the fixed column. When the overhead crane lifts the workpiece, the crossbeam is rotated to the side away from the fixed column to facilitate the overhead crane to lift the workpiece, prevent the hook from colliding with the cylinder and ensure production safety.

[0012] 2. A clamping component is set at the bottom of the pressure head. The combination structure of the support plate and multiple pressure feet allows the pressure feet to be adjusted on the support plate, which facilitates precise alignment between the pressure feet and the anode steel claw and helps the pressure feet to stably clamp the anode steel claw.
