Saw blade carrier clamping device with self-centering

Abstract

The invention provides a saw blade bearing and clamping device with an automatic centering function. The saw blade bearing and clamping device comprises a mounting base, a driver, a stationary shaft sleeve, a sliding shaft, a first butting block and a centering alignment mechanism. The stationary shaft sleeve is provided with a hollow structure with two ends open, and arranged on the mounting base. The driver is arranged at one end of the stationary shaft sleeve, the sliding shaft is slidingly arranged in the hollow structure of the stationary shaft sleeve, one end of the sliding shaft is connected to the output end of the driver, the other end of the sliding shaft extends out of the other end of the stationary shaft sleeve to form a bearing end, and the first butting block is detachably mounted at the bearing end. The centering alignment mechanism comprises an elastic part and a bearing sleeve part, one end, away from the stationary shaft sleeve, of the bearing sleeve part gradually diminishes towards the direction away from the stationary shaft sleeve to form a reducing surface bearing portion, the bearing sleeve part is sleeved on the sliding shaft slidably, the elastic part constantly drives the bearing sleeve part to move toward the direction away from the stationary shaft sleeve, and a saw blade is sleeved on the reducing surface bearing portion and clamped between the stationary shaft sleeve and the first butting block.

Description

Technical field [0001] The invention relates to the field of saw blade processing, in particular to a saw blade carrying and clamping device with automatic centering, which is suitable for being installed on a saw blade processing machine and carrying and clamping and positioning the saw blade. Background technique [0002] With the continuous development of the economy, the continuous progress of science and technology and the continuous advancement of the industrial modernization process, the processing and manufacturing industries in the industrial field are moving towards mechanization, intelligence, high integration and high efficiency, and they are in the tool maintenance , The processing field is particularly important. [0003] As we all know, circular saw blades are an indispensable processing tool in the machinery manufacturing industry. In order to improve the wear resistance of circular saw blades, generally in addition to reasonable design on the material and manufactu...

Problems solved by technology

[0004] In the above-mentioned process of welding or grinding the alloy welding piece on the circular saw blade, the circular saw blade needs to be loaded and clamped and positioned. However, on the one hand, the circular saw blade in the prior art The structure of the mechanism for carrying and clamping and positioning the saw blade is extremely complicated, and it is prone to unreliable clamping and positioning, and it is easy to loosen, which seriously affects the processing quality of the circular saw blade, and the operation of carrying and clamping and positioning is extremely cumbersome and inefficient. There are also defects that are difficult to install, difficult to control, large energy consumption and difficult to maintain, which greatly increases the cost of saw blade production and processing; The existing processing conditions cannot eliminate this error. If the load-bearing hole of the saw blade is sleeved on the cylindrical load-bearing part, there must be a fit gap, resulting in that the centerline of the saw blade does not coincide with the centerline of the load-bearing part, making During the rotation of the saw blade, the center line of the saw blade will deviate and swing, which makes the rotation of the saw blade extremely unstable, resulting in poor consistency in the processing of the alloy welding piece on the saw blade, which seriously affects the alloy welding on the saw blade. The quality of the processing of the slices
