Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Example 1: a high-precision metal band sawing machine stable in operation comprises a base 1, a workbench 2, a fixed clamping block, a movable clamping block 3, a saw wheel frame 4, a vertical frame 5, a sliding block 6, a clamping wheel 7 and a band saw 8, and further comprises a threaded rod 9, a pressing plate 10, a clamping wheel mounting block 11, a clamping wheel shaft 12 and a wheel shaft nut 13, wherein the threaded rod is arranged on one side of the workbench far away from the fixed clamping block and the movable clamping block in the width direction, the two threaded rods are respectively and symmetrically distributed on two sides of the center line of the workbench in the length direction, pressing plate through holes for the threaded rods to pass through are formed in the positions, corresponding to the threaded rods, of two sides of the pressing plate in the length direction, locking nuts are connected to the threaded rod through threads, the clamping wheel mounting block is fixedly connected to the side face of the sliding block, a waist-shaped groove 14 is formed in the clamping wheel mounting block, threads are arranged at one end of the clamping, the size of the clamping wheel shaft is matched with the kidney-shaped groove, the clamping wheel shaft penetrates through the kidney-shaped groove, a wheel shaft nut is tightly matched with the surface of the clamping wheel mounting block, and the band saw is close to the upper surface of the workbench.

After the embodiment is adopted, the pressing plate is used for pressing down raw materials or parts, the raw materials or the parts are fixed left and right by matching with the original fixed clamping blocks and the original movable clamping blocks, the effect is good, and the jumping in the machining process is prevented. The number of the locking nuts is set according to different requirements, for example, only one locking nut is set for each threaded rod, the pressing plate is used for being lapped on raw materials or parts and the locking nut is used for preventing jumping, but the cylindrical parts such as pipes with thin wall thickness are driven to rotate by the aid of devices such as the chuck, friction can be generated between the pressing plate and the parts, and therefore two locking nuts are preferably arranged on each threaded rod and are respectively located above and below the pressing plate, so that the height of the pressing plate can be adjusted according to requirements, and the height of the pressing plate can be maintained. The clamping wheel is arranged on the clamping wheel mounting block, the waist-shaped groove is formed in the clamping wheel mounting block, threads are arranged at one end of the clamping wheel shaft and used for connecting the wheel shaft nut, the clamping wheel is located at the other end of the clamping wheel shaft, the size of the clamping wheel shaft is matched with the waist-shaped groove, the clamping wheel shaft penetrates through the waist-shaped groove, the wheel shaft nut is tightly matched with the surface of the clamping wheel mounting block, the distance between the clamping wheels can be adjusted according to different band saws, and the universality of equipment is improved.
