Problems solved by technology

[0005] However, for the first type of abrasive belt grinding tool, since the abrasive belt needs to be driven by the driving roller to produce rotation, the driving roller set on the working head And driven rollers cause the structure of the working head to be complicated, and further make the volume of the whole working head larger, and it is inconvenient to use in some places with small workpiece environments (such as corners, etc.)
For the second type of abrasive belt grinding tool, due to the use of a non-closed abrasive belt, in actual work, the abrasive belt that plays a grinding role is only limited to the middle part of the entire abrasive belt, thereby reducing the utilization rate of the abrasive belt.
Moreover, also because the middle part of the abrasive belt has been used as a grinding part, when the middle part is ground flat, the whole abrasive belt cannot continue to be used, resulting in a limited service life of the abrasive belt

Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] see figure 1 , a preferred embodiment of the present invention discloses an abrasive belt grinding tool, which is suitable for surface grinding of a workpiece 4 with a curved surface (see FIG. 3, mainly involving a tubular profile). The abrasive belt grinding tool includes a main machine 1 and a working head 2 installed on the main machine 1 . The main engine 1 here is a power tool that can output rotating and reciprocating torque. This power tool has been widely used in the industry, such as the multifunctional machine produced by companies such as FEIN and BOSCH. Its structure and principle are located in the main engine 1. The motor drives the eccentric wheel connected to the motor to rotate, and the shift fork connected to the eccentric wheel is driven by the eccentric rotation of the eccentric wheel to generate rotationa...

Abstract

The invention relates to an abrasive belt type grinding tool which comprises a main machine for outputting a rotating and reciprocating torque, and working heads (2,5,6,7,8) detachably arranged on the main machine (1), wherein the working heads (2,5,6,7,8) comprise connecting parts (21,51,61,71,81) and at least two support ends (231,241,641,642,741,742,841,842); the support ends (231,241,641,642,741,742,841,842) support and guide a closed annular abrasive belt (3); and the annular abrasive belt (3) and the working heads (2,5,6,7,8) are jointly driven by the main machine (1) to rotate and reciprocate. The abrasive belt type grinding tool can grind workpiece with curved surfaces, in particular to surfaces of tubular sections.

Description

technical field [0001] The invention relates to a grinding tool, in particular to an abrasive belt grinding tool using an abrasive belt working head, which is used for grinding the surface of a tubular profile workpiece. Background technique [0002] A belt machine is one of the commonly used grinding tools, mainly for grinding the surface of a workpiece (such as wood, etc.), removing burrs and making it smooth, and then it can be used normally. However, the belt sander or sander that is used to grind the surface of the workpiece usually has a larger sanding plane, and a larger sandpaper is pasted on the sanding plane, resulting in a larger volume of the sander or sander. Large, it is only suitable for large-area flat profile surface grinding, and for profiles with a small area and curved surfaces, such as common tubular profiles, such a belt machine or sander cannot be used. [0003] Therefore, in response to this demand, the industry has designed miniaturized abrasive bel...
