The special tool is simple in structure and wide in application range, can meet the repairing requirements of T-shaped grooves of the mining headstock with various specifications of specific shapes, and is simple, clear, visual, economical and practical in whole operation.
Description
Technical Field
The utility model relates to an adjustable milling tool for a head frame T-shaped groove, which is mainly used for repairing and processing the head frame T-shaped groove for mines with specific shapes and multiple specifications.
Background
The T-shaped groove of the mining headstock is used for assembling a connecting bolt for mounting a mining conveyor transmission device, and the position requirements of the anti-rotation inner groove of the bolt of the headstock and the through hole of the bolt are high. The anti-rotation inner groove is processed on the machine head frame part, the bolt through hole is processed on the machine head frame part, and position errors are easily generated between the anti-rotation inner groove and the machine head frame part, so that the connecting bolt cannot be installed; the traditional processing method is that a T-shaped groove milling cutter with a fixed diameter is used for repairing, and is limited by different specifications of T-shaped grooves, so that the processing requirement cannot be ensured; secondly, flame is used for cutting the interference part of the bolt, so that the quality requirement cannot be met.
Disclosure of Invention
The utility model aims to provide an adjustable milling tool for a T-shaped groove of a machine head frame, so as to realize the repairing and processing process of the T-shaped groove of the machine head for mines with specific shapes and multiple specifications.
The key technology of the utility model is as follows: the tool comprises a tool handle, a lower slide block, a compression screw, an indexable alloy blade, an upper slide block and a compression screw; the indexable alloy blade is respectively connected and fastened with the lower sliding block and the upper sliding block through a cutter pressing screw; the lower slide block and the upper slide block are connected with the key groove of the knife handle through keys and are fastened through compression screws; the headstock is fixed with a machine tool workbench through a pressing plate bolt; the knife handle is connected with a main shaft of the machine tool through a blind rivet arranged at the rear end of the knife handle;
The lower slide block and the upper slide block can be selected according to the outline size of a part to be processed, and when the T-shaped groove H of the headstock is milled, the cutting radius of the indexable alloy blade can be adjusted by the sliding of the lower slide block and the upper slide block and the fastening of a compression screw;
When in use, the machine head frame is placed on a machine tool workbench, and is fixed with the machine tool workbench by using a pressing plate bolt; and the rear end of the cutter handle is provided with a blind rivet which is connected with a main shaft of the machine tool, and the milling can be realized by pressing the blind rivet by a pressing screw after the lengths of the upper sliding block and the lower sliding block are adjusted to be proper according to the size and the cutting amount of a T-shaped groove to be processed of the machine head frame.
The beneficial effects of the utility model are as follows:
1. the repairing and processing process of T-shaped grooves of the headstock with specific shapes and various specifications can be realized; 2. the degree of dependence of the repair of the T-shaped groove of the headstock on the specification of a T-shaped groove tool can be reduced; 3. the precision requirement of replacing flame cutting by machining the T-shaped groove of the headstock at the repairing moment can be met;
the technical scheme of the utility model is described in detail below with reference to the accompanying drawings and the specific embodiments.

FIG. 1 is a schematic diagram of the milling operation of a T-shaped slot of a headstock of the present utility model;
FIG. 2 is a front view of the initial dimensions of the adjustable milling tool for the T-shaped groove of the headstock of the present utility model;
Fig. 3 is a front view of the adjustable dimension of the milling tool for the T-shaped groove of the headstock.
In the figure: 1 knife handle, 2 lower slide block, 3 compression screw, 4 indexable alloy blade, 5 upper slide block, 6 compression screw and 7 headstock.
Detailed Description
As shown in fig. 1, 2 and 3, before repairing the T-shaped groove of the headstock, the headstock is placed on a machine tool workbench, and is fixed with the machine tool workbench by using a pressing plate bolt; the indexable alloy blade is respectively fastened in the blade mounting grooves of the upper sliding block and the lower sliding block by a cutter pressing screw; the keys of the upper sliding block and the lower sliding block are arranged in the key groove of the cutter handle and are slightly fastened by the compression screw to prevent falling off; loading the cutter handle into a main shaft of a machine tool, and locking; measuring the dimension H of the T-shaped groove of the headstock, measuring the initial dimension D1 of the milling tool, determining the machining allowance, adjusting the extension delta L of the upper sliding block and the lower sliding block, and fastening a compression screw after the dimension D2 of the milling tool meets the machining requirement, so that the milling of the T-shaped groove can be realized.
It should be understood that the detailed description of the technical solution of the present utility model, given by way of preferred embodiments, is illustrative and not restrictive. Modifications and substitutions for some technical features of the embodiments may be made by those skilled in the art on the basis of the present description, and the essence of the corresponding technical solutions does not deviate from the spirit and scope of the technical solutions of the embodiments.
