Description

Automatic alignment structure for machining tool and sleeve

This work is about the assembly of machining center tools, especially an automatic alignment structure of machining center tools and their sleeves.

According to the generally known machining tool and sleeve assembly structure, the tool can be a boring tool, a turning tool, a milling tool, a hinge tool, a drill bit, a rotary file, a chamfering tool, a dovetail tool, etc., one end of the tool is provided with a shank, the other end is provided with a tool body, the outer periphery of the shank is provided with a flat cut surface, one end of the sleeve is provided with a tool hole, the outer periphery of the sleeve is provided with a plurality of screw holes connected to the tool hole, and a tightening bolt is screwed in each of the screw holes.

When the tool is assembled with the sleeve, the shank of the tool is inserted into the tool hole of the sleeve, and the tool is manually rotated for calibration and adjustment so that the tool body faces a specific direction and the flat surface of the tool is aligned with the multiple screw holes of the sleeve. Then, each of the tightening bolts is tightened against the flat surface of the tool to fix the tool on the sleeve.

However, the tool and sleeve assembly structure of the known processing machine tool requires manual rotation of the tool for calibration and adjustment during assembly before each clamping bolt can be tightened to the flat cut surface of the tool to complete the assembly between the tool and the sleeve. Therefore, the operation of assembling the tool to the sleeve is cumbersome and time-consuming, and the assembly efficiency is low. This is obviously not an ideal design and needs to be improved and broken through.

The author of this invention, in view of the above-mentioned shortcomings of the known machining center tool and its sleeve assembly structure, came up with the idea of creating this invention. After much discussion and trial production of samples, as well as many revisions and improvements, this invention was launched.

The invention provides a processing machine tool and its sleeve automatic alignment structure, comprising: a tool, one end of which is provided with a shank, and the other end of which is provided with a tool body, the end of the shank away from the tool is provided with a guiding bevel; and a sleeve, which is provided with a set end, the set end is provided with a tool hole, the tool hole is just for the shank of the tool to be inserted, the outer periphery of the sleeve is provided with a pin hole penetrating the tool hole, the pin hole is provided for a positioning pin to be inserted, so that the positioning pin passes through the tool hole, the outer periphery of the sleeve is at the set end At least one screw hole is provided between the tool and the pin hole, and at least one locking bolt is screwed on the screw hole; when the tool and the sleeve are assembled, the shank of the tool is inserted into the tool hole of the sleeve, and the guide bevel of the tool and the outer periphery of the locating pin slide against each other, driving the tool to automatically rotate and find the position, until the guide bevel of the tool and the outer periphery of the locating pin are tangentially abutted to achieve accurate alignment, and then the locking bolt is screwed to tighten the outer periphery of the tool to fix the tool on the sleeve.

The main purpose of the automatic alignment structure of the tool and sleeve of the creative processing machine is that when the tool and the sleeve are assembled, the tool can automatically rotate to find the position and align easily, so as to achieve simple and fast assembly and improve work efficiency.

The following is a further description of the preferred embodiment of this invention in conjunction with the diagram, in the hope that people familiar with the relevant technology of this invention can implement it according to the description in this manual.

First, please refer to the first to sixth figures, which show the automatic alignment structure of the tool and sleeve of the processing machine, including: a tool 10 and a sleeve 20.

The tool 10 has a handle 11 at one end and a tool body 12 at the other end. The end of the handle 11 away from the tool 10 is provided with a guiding bevel 111, and the slope θ of the guiding bevel 111 is 20 degrees to 60 degrees. In this embodiment, the handle 11 is a round rod, and the slope θ of the guiding bevel 111 is 30 degrees. The end of the tool body 12 away from the handle 11 is provided with a tool head 121. The tool 10 can be a boring tool, a turning tool, a milling tool, a hinge tool, a drill bit, a rotary file, a chamfering tool, a dovetail tool, etc.

The sleeve 20 is provided with a set end 21, and the set end 21 is provided with a tool hole 22, and the tool hole 22 is just for the shank 11 of the tool 10 to be inserted. The outer periphery of the sleeve 20 is provided with a pin hole 23 that penetrates the tool hole 22, and the pin hole 23 is provided for a positioning pin 24 to be inserted, so that the positioning pin 24 penetrates the tool hole 22. The outer periphery of the sleeve 20 is provided with at least one screw hole 25 between the set end 21 and the pin hole 23, and the at least one screw hole 25 is provided for at least one clamping bolt 26 to be screwed. In this embodiment, the positioning pin 24 is a round rod shape, and the outer periphery of the sleeve 20 is provided with two screw holes 25 between the set end 21 and the pin hole 23, and the two screw holes 25 are provided for two clamping bolts 26 to be screwed.

When the tool 10 and the sleeve 20 are assembled, please refer to Figures 7 and 8, insert the shank 11 of the tool 10 into the tool hole 22 of the sleeve 20, and during the insertion process, the guiding bevel 111 of the tool 10 contacts the locating pin 24, and the guiding bevel 111 of the tool 10 and the outer periphery of the locating pin 24 slide against each other, driving the tool 10 to automatically rotate and find its position until the guiding bevel 111 of the tool 10 is tangentially abutted against the outer periphery of the locating pin 24, so that the tool 10 is accurately aligned, and then the tightening bolt 26 is tightened to tighten the outer periphery of the tool 10 with a tool, and the guiding bevel 111 of the tool 10 is tangentially abutted against the outer periphery of the locating pin 24, so as to increase the fixing and anti-rotation capabilities, so that the tool 10 is stably fixed on the sleeve 20, and the assembly is completed.

The structure of the above specific embodiment can obtain the following benefits:

The invention relates to a processing machine tool and its sleeve automatic alignment structure. When the tool 10 and the sleeve 20 are assembled, the guiding bevel 111 of the tool 10 contacts the positioning pin 24. The guiding bevel 111 of the tool 10 and the outer periphery of the positioning pin 24 slide against each other, driving the tool 10 to automatically rotate and find the position, and aligning is easy, so as to achieve simple and fast assembly, improve work efficiency, and enhance convenience and practicality.
