Description

TECHNICAL FIELD

[0001] The utility model relates to tooling technical field especially relates to a grinding tube placing tooling. BACKGROUND

[0002] The characteristics of silicon carbide grinding tube: extremely low abrasion, can prevent material pollution, suitable for various grinding and dispersion occasions, extremely high grinding efficiency, extremely long service life, and lower comprehensive operation cost. Silicon carbide has the above characteristics and is widely used in the field of grinding technology, but the silicon carbide material has the characteristics of being fragile, so rigid impact should be avoided during production and transportation of silicon carbide grinding tube, thereby reducing the probability of breaking of silicon carbide grinding tube.

[0003] The existing silicon carbide grinding tube placing tooling is mostly fixedly arranged, and a small number of upper surfaces are bonded with elastic rubber pads to improve the buffering performance. Although the rubber pad can improve the buffering performance, the buffering performance is still poor. The grinding tube made of silicon carbide material often needs to be placed on the placing tooling with the help of a crane and other auxiliary tools. The worker needs to control the falling distance when the crane is hoisted. If the worker is not skilled or absent-minded, the grinding tube is likely to drop too much, and the silicon carbide grinding tube and the placing tooling are likely to produce rigid impact, causing the grinding tube to break. The ordinary spring arrangement can improve the buffering performance of the placing tooling, but it is difficult to stably fix the silicon carbide grinding tube. The spring is likely to deform under stress, and it is difficult to process the silicon carbide grinding tube. UTILITY MODEL CONTENTS

[0004] In view of the above defects, the utility model aims at providing a grinding tube placing tooling which can place the grinding tube, improve the buffering performance to avoid rigid impact between the grinding tube and the placing tooling, thereby avoiding the stress breakage of the silicon carbide grinding tube.

[0012] This utility model provides a grinding tube placement fixture, including a base, with several elastic support devices arranged above the base. The elastic support devices improve the buffering performance of the grinding tube placement fixture while providing support for the grinding tube, reducing the probability of rigid collisions during the placement of the silicon carbide grinding tube. Each elastic support device includes a sleeve, a lifting rod, a compression spring, a threaded column, a first nut, a second nut, and a support frame. The bottom end of the sleeve is fixedly connected to the base, and a compression spring is installed inside the sleeve, which helps improve the buffering performance. A lifting rod is arranged above the compression spring, and the sleeve is slidably fitted onto the outside of the lifting rod. The lifting rod, in conjunction with the compression spring, facilitates lifting and lowering. The sliding connection of the sleeve to the lifting rod ensures that the lifting rod can only move up and down within the sleeve and cannot rotate, thus preventing... The lifting rod's movement direction deviates; a threaded column is fixedly connected to the top of the lifting rod, with a first nut fitting on the threaded column. An external thread of the same type as the threaded column is located above the sleeve, with a second nut fitting on the external thread. The first nut is rotatably connected to the second nut above it. This rotatable connection allows both the first and second nuts to rotate independently. The engagement of the first nut with the threaded column and the second nut with the external thread restricts the movement of the lifting rod. Furthermore, rotating the first nut independently after the second nut engages with the external thread allows adjustment of the support frame's height, facilitating the horizontal placement of the grinding tube. With the lifting rod's movement restricted, the support frame provides stable support during grinding tube processing. The top of the threaded column is fixedly connected to the bottom of the support frame, which facilitates the placement of the grinding tube and provides support. Attached Figure Description
