Embodiment 1

[0025] A fine-tuning fine-boring tool holder, which consists of: a tool holder body 1 with a blade holder 2 inside, the blade holder is a sliding body with a rectangular groove, and the tool holder body Fine-tuning bolts 5, cylindrical pins 6, and countersunk screws 4 are respectively installed on the front end surface. One side of the knife holder body has a slope, and the hexagon socket head screw 3 is installed on the slope. The knife holder body The inclined surface on the other side is equipped with an adjustment block 8, and the lower plane of the adjustment block is equipped with a hexagon socket head screw 7.

Embodiment 2

[0027] According to the fine-tuning fine boring tool holder described in Embodiment 1, the adjustment precision of the fine-tuning bolt is Φ0.01mm / grid, and the radial adjustment stroke is 0.3mm.

Embodiment 3

[0029] A fine-tuning and fine-tuning boring tool holder and an adjustment method thereof. The method firstly fixes the fine-tuning boring tool holder and the tool, installs the fine-tuning boring tool holder accurately, and fixes the tool on the tool holder by tightening the hexagon socket flat head screw;

[0030] To adjust the fine-tuning boring tool seat, when adjusting the axial direction, use a wrench to adjust the rotation and length of the hexagon socket head screw, thereby changing the compression degree of the adjustment block and changing the axial position of the tool seat; on the fine-tuning boring tool seat , by adjusting the compression degree of the adjustment block, the axial S1=±1.5mm adjustment range can be realized;

[0031] During the radial adjustment, it is adjusted by the fine-tuning bolt, and the scale display structure shows that the adjustment accuracy is Φ0.01mm / grid, and the radial adjustment amount is S2=0.3mm, so as to change the radial position of...

Abstract

The invention relates to a fine adjustment fine boring tool apron and an adjustment method. Currently, most boring toolholders produced in China do not have the function of displaying numerical value type fine adjustment, only can perform simple axial and radial adjustment, utilizes thread transmission mechanisms to perform rough adjustment of mechanisms through the screw stretching length, and are lower in adjustment accuracy. The fine adjustment fine boring tool apron comprises a tool apron body (1), wherein a blade bearing (2) is arranged in the tool apron body and is a slip mass provided with a rectangular groove; a fine adjustment bolt (5), a straight pin (6) and a sunk screw (4) are mounted on the front end face of the tool apron body respectively; an oblique plane is arranged on one side of the tool apron body; a hexagon socket button head screw (3) is mounted on the oblique plane; an adjustment block (8) is matched with the oblique plane on the other side of the tool apron body; a hexagon sunk screw (7) is mounted on the lower surface of the adjustment block. The invention is applicable to fine adjustment fine boring tool aprons.

Description

Technical field: [0001] The invention relates to a fine-tuning fine boring tool holder and an adjusting method. Background technique: [0002] At present, most of the boring tool holders produced in China do not have the function of displaying numerical fine-tuning, and can only perform simple axial and radial adjustments. The threaded transmission mechanism is used to perform rough adjustment of the mechanism through the screw extension length, and the adjustment accuracy is relatively low. Low. The fine-tuning fine boring tool holder is a composite boring tool spare part used in the semi-finishing and finishing machining of holes in the machinery manufacturing industry. This type of product is widely used in composite processing such as complex stepped holes and chamfering in one time in the automotive and other industries. , In mechanical manufacturing and processing, high speed and high precision have become an inevitable trend of development. This product has improved...
