Problems solved by technology

The hole saw is installed on a power tool with rotary output such as an electric drill, and can efficiently complete the processing of the hole at one time. However, due to the limitation of its rotary output form, the hole saw can usually only be constructed as a hollow section The saw blade is circular, so it is only suitable for processing circular holes, and it cannot be processed for those holes with sudden changes in hole shape and non-smooth transition

Embodiment Construction

[0027] Such as Figure 1 to Figure 6 As shown, the power tool 10 of the present invention drives the working element in an oscillating manner to process the workpiece 8. The casing of the working head area of ​​the power tool 10 supports an output shaft 2, and the output shaft 2 is driven by the vibrating support 1 around its longitudinal direction. The axis reciprocates with a small yaw angle and high frequency, and the shaft end of the output shaft 2 is equipped with a hole opener 20, combined with Figure 7 to Figure 9 , the hole saw 20 includes a fastening portion 21 having a receptacle 23 for mounting to the vibratory tool 10, the receptacle 23 defining a longitudinal axis Y around which the hole saw 20 can Driven in vibration, the fastening part 21 is connected with a hollow tool 22 having a material processing region 22', the direction of feed of the tool 22 in the workpiece being machined is substantially parallel to the longitudinal axis Y. The cutter 20 can be confi...

Abstract

The invention provides a tapper used for an oscillation tool, and the tapper comprises a fastening part, wherein the fastening part is provided with a receiver used for being installed on the oscillation tool, the receiver limits a longitudinal axis, and the tapper can be driven around the longitudinal axis in a vibration mode. The tapper also comprises a cutter which is connected with the fastening part and is provided with a material processing area, wherein the feeding direction of the cutter in a processed workpiece is substantially parallel to the longitudinal axis, and the material processing area is constructed into triangle, square or pentacle on the circumference. The application occasion of the oscillation tool is enlarged by arranging the tapper on the oscillation tool, and the tapping efficiency on the workpiece is improved. In addition, the tapper installed on the oscillation tool can be constructed into cutter forms, such as triangle, square and the like, and the limitation that the tapper is only suitable for tapping round holes in the prior art can be broken through.

Description

technical field [0001] The invention relates to a power tool, in particular to a power tool whose power output shaft oscillates back and forth at a high frequency and small yaw angle and drives a tool mounted on it to perform material removal operations in a vibrating manner. Background technique [0002] Oscillating tools, also known as multi-function tools, have multiple functions according to the different types of accessories installed on their working heads, such as saw blades for sawing, sand discs for grinding, etc., and their working principle is: Oscillation The driver drives the accessory installed on its working head to reciprocate and swing at high frequency with a small yaw angle to perform material removal operations. [0003] Among them, the oscillating tool equipped with a saw blade is widely used in sawing operations of various plates, pipes, etc., and has the advantages of high cutting efficiency, convenient operation, and flexible application to various oc...
