Description

Technical Field

[0001] The utility model relates to the technical field of boring devices, in particular to a component boring device. Background Art

[0002] Boring is a metal cutting process used to machine the inner hole of a workpiece. A boring device is a mechanical device or tool used to perform this process. Boring is performed on the basis of an existing hole. It is usually used to machine holes with high precision or large diameter. The tool used in the boring process is usually called a boring tool.

[0003] The boring bar needs to be replaced frequently when the boring tool is in use. When replacing the boring bar, the existing boring tool needs to loosen the locking mechanism with a wrench and tighten it again after replacement. The operation is relatively complicated, resulting in longer downtime and may increase the risk of boring bar wear. Utility Model Content

A positioning hole is provided at the side wall of the boring bar. A through groove is also provided at the side wall of the tool holder, and an annular groove is provided at the outer wall. An installation chamber penetrating the annular groove and the slot hole is provided inside the tool holder; the installation chamber is connected to the through groove. The mounting part includes a pressing plate; the pressing plate is arranged on the annular groove, the orientation of the pressing plate corresponds to the through groove one by one, a positioning column is connected to one end of the pressing plate close to the tool holder, the positioning column passes through the installation chamber, and cooperates with the positioning hole by sliding between the slot hole and the annular groove; a spring is wound around one end of the positioning column close to the pressing plate, and a positioning block is also connected to the side wall of the positioning column; an adjustment surface is provided on the positioning block. A second spring is arranged on the inner wall of the through slot; the other end of the second spring is connected to a stopper; the stopper maintains a horizontal moving track through the through slot, one end of the stopper extends to the outside of the tool holder, the other end extends into the installation chamber, and is provided with an adjustment surface second that cooperates with the adjustment surface one of the positioning block.

DETAILED DESCRIPTION

[0020] Embodiment 1

[0021] like Figure 1-6As shown, a component boring device proposed by the utility model includes a tool holder 1, a slot hole 101 is provided at the front end of the tool holder 1, and a plurality of mounting parts are arranged along the outer periphery of the slot hole 101; a boring bar 6 is inserted into the slot hole 101; the boring bar 6 is installed and disassembled by cooperating with the mounting parts. A positioning hole 601 is provided at the side wall of the boring bar 6. A through groove 2 is also provided at the side wall of the tool holder 1, and an annular groove 102 is provided at the outer wall. An installation chamber 103 penetrating the annular groove 102 and the slot hole 101 is provided inside the tool holder 1; the installation chamber 103 is connected to the through groove 2.

[0022] The mounting part includes a pressing plate 7; the pressing plate 7 is arranged on the annular groove 102, and the orientation of the pressing plate 7 corresponds one-to-one to the through groove 2; the end of the pressing plate 7 close to the tool holder 1 is connected with a positioning column 9, the positioning column 9 passes through the mounting chamber 103, and cooperates with the positioning hole 601 by sliding between the slot 101 and the annular groove 102; a spring 10 is wound around the end of the positioning column 9 close to the pressing plate 7, and a positioning block 11 is also connected to the side wall of the positioning column 9; an adjustment surface 1 is arranged on the positioning block 11.

[0023] A spring 2 3 is provided on the inner wall of the through slot 2; the other end of the spring 2 3 is connected to a stopper 4; the stopper 4 maintains a horizontal moving trajectory through the through slot 2, one end of the stopper 4 extends to the outside of the tool holder 1, and the other end extends into the installation chamber 103, and is provided with an adjustment surface 2 that cooperates with the adjustment surface 1 of the positioning block 11.

[0024] The boring bar 6 can be easily replaced by pressing the pressing plate 7 and moving the stop block 4, replacing the traditional complicated operation of loosening the locking mechanism with a wrench and then tightening it after replacement, which greatly shortens the operation time and reduces the risk of boring bar wear.

[0025] Embodiment 2

[0026] like Figure 1-6 As shown, a component boring device proposed by the utility model, compared with the first embodiment, this embodiment also includes: two groups of mounting parts are symmetrically arranged about the slot hole 101, so that the fixing of the boring rod 6 is more stable. The horizontally movable stopper 4 is slidably connected to the through slot 2, and its adjustment surface 2 is an inclined structure, so that when the positioning block 11 moves downward, the stopper 4 can be easily pushed to move horizontally and compress the spring 2 3. The spring 2 3 is arranged on the high side of the adjustment surface 2, so that the spring 2 3 will not interfere with the movement of the positioning block 11. A limiting rod 5 is provided at the side wall of the through slot 2, and a through hole is opened at the side wall of the stopper 4. The limiting rod 5 passes through the stopper 4 through the through hole to ensure that the stopper 4 will not be skewed when the stopper 4 is moved. A silicone pad 8 is connected to the end of the pressing plate 7 away from the tool holder 1, which is convenient for pressing the positioning column 9. One end of the spring 10 is connected to the pressing plate 7, and the other end is connected to the side wall of the annular groove 102.

[0027] The working principle of the utility model is as follows: when the boring bar 6 needs to be replaced, first, the stopper 4 is moved along the limiting rod 5 to one side of the spring 2 3, at which time the spring 2 3 is compressed, the spring 10 rebounds, and the positioning block 11 moves toward the direction of the pressing plate 7 under the action of the spring 10, and when the positioning block 11 moves to the top of the stopper 4, the stopper 4 is released to make the spring 2 3 rebound, so that the adjustment surface 2 on the stopper 4 abuts against the positioning block 11. At this time, the positioning column 9 is separated from the positioning hole 601, so that the old boring bar 6 can be taken out from the slot 101, and the new boring bar 6 can be reinserted into the slot 101.

[0028] After the new boring bar 6 is placed, the pressing plate 7 is pressed toward the slot 101 through the silicone pad 8, so that the spring 10 is compressed, and the positioning block 11 is driven to move toward the slot 101, so that the adjustment surface 1 and the adjustment surface 2 are abutted, and the stopper 4 is pushed to move along the limit rod 5 toward the side of the spring 2 3, so that the spring 2 3 is compressed. When the positioning block 11 moves to the bottom of the stopper 4, the spring 2 3 is reset and pushes the stopper 4 to move outward and clamp the positioning block 11, so that the positioning column 9 is limited and inserted in the positioning hole 601. At this time, the replacement of the boring bar 6 is completed.

[0029] The boring bar 6 can be easily replaced by pressing the pressing plate 7 and moving the stop block 4, replacing the traditional complicated operation of loosening the locking mechanism with a wrench and then tightening it after replacement, which greatly shortens the operation time and reduces the risk of boring bar wear.

[0030] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
