[Prior Art] Lathes are mainly used in metal processing. The principle is to use motor power to drive the head and drive the rotation and intrusion, resulting in __. The simple county bed structure generally includes the transmission supervisor and the rotating read miscellaneous. With this _ there is a knife holder for the __ knife. As shown in the first figure, the conventional knife holder 10 is provided with a cutter groove n on the side, and the cutter slot ^ can be placed in the car 12' and the car 13 is screwed into the cutter continent by a plurality of turning tools. . When the _ car does not scale the rotation, the car cutter 12 will turn the height of the towel. If the turning tool 12 is aligned with the center height of the workpiece, or the turning tool 12 is not at a level of sound relative to the center of the workpiece, the turning operation may cause problems such as turning of the turning tool or the workpiece, and the cutting is not easily eliminated. In order to solve the workpiece (four degrees) in the micro-calibration position, the spacer 14 is placed in the tool slot 11 below the turning tool 2, and the height of the turning tool 12 is adjusted by the thickness of the spacer 14. Those skilled in the art know that the choice of the thickness of the gasket 14 depends on the experience of the operating technician. The steps of the turning tool adjustment will become very troublesome, and it is difficult to fine-tune the height of the turning tool 12, so the turning of the turning tool is performed. Quasi-problem. [New content] This case proposes an improvement scheme to solve the ugly problem that the conventional knife holder faces when adjusting the height of the turning tool. The improved scheme includes: · M325184 a fixed base fixed to the bed of the lathe; The nesting, the god-tool slot, is provided for the car, and the tool is recorded at the front of the fixed base, so that the tool can be nested between the two (4) a moving joint structure; a displacement adjusting component disposed at a top of the base and connected to the knife seat for controlling the linear movement of the tool rear seat; - a positioning component disposed on the pedestal base The tool insert provides a force to position the tool insert at an intended height. The effect of the present invention is to rotate the adjusting bolt to adjust the height of the tool insert and the turning tool, so that the turning tool tip is at the level of the work h is off, and the # turning tool is positioned with the above positioning component when the desired position is fixed. Rotating the shackle _ The program for the height of the turning tool is very easy to read and implement, and the height of the turning tool can be fine-tuned to make the relative position of the turning tool and the center of the workpiece as close as possible within the accuracy range. [Embodiment] The embodiment of the lathe tool holder shown in Figures 2, 3 and 4 includes a fixed base 20, a tool insert 30, a displacement adjusting assembly 4A, and a positioning assembly 5''. The fixed base 20 is fixed to a bed base of a lathe (not shown). The front portion of the cutter rear seat 3 is provided with a cutter groove 31, and the cutter 32 is provided on the towel, and is fixed by a plurality of lock members 33 provided on the top of the cutter insert 3Q. The tool rear seat 3 is disposed at a front portion of the fixed base 2, and has an engagement structure 35 for moving the tool holder 30 up and down along the fixed base 2''. The joint structure 35 is realized by the dovetail groove 351 and the dovetail seat 352 in the embodiment of the present invention. The displacement adjusting component 4 is disposed at the top of the fixed base 2〇 and connected to the tool insert 3〇, and the M325184 controls the tool insert 3〇 to move up and down to adjust the position of the turning tool 32. The main function is to pass through the axially-removed screw 42 in the axial direction, and the positioning block 41 is fixed to the top of the fixed base 20 with the locking component side. The tool is inserted into the lion threaded hole. Please refer to the fifth figure at the same time. Rotating the adjusting bolt 42 can make the tool green 3〇 move up and down linearly, and then change the height of the turning tool 32. At the same time, referring to the sixth item, the above-mentioned fixed 5G system is _tool nesting and positioning is placed on a positioning bolt 51 which is intended to be placed on the fixed base 3, and is oriented inward. When the lock is applied, the above-mentioned joint structure 35 is provided with a pressing force, so that the cutter seat is fixed. In the embodiment, the positioning bolt 51 acts in a direction opposite to the above-mentioned dovetail groove 351 and the tailstock seat 352. The tailing groove, such as the inner side-side side-filling block 52, is mainly used to eliminate the groove between the seat and the seat. In the gap, the positioning screw 51 described above applies a lateral force to the filling block 52, and the filling block 1 is forced to the tailstock to achieve the purpose of fixing the tool insert 30. As shown in the fifth and sixth figures, the adjustment of the adjusting bolt 42 can adjust the height of the tool insert 3〇 and the turning tool 32. When the turning tool 32 is at the desired height, the tool is embedded by the positioning component 5〇 described above. The seat is fixed. In the example shown in the seventh figure, the turning tool 32 is at the level of the position of the turning tool tip relative to the center axis of the workpiece 6, that is, the turning tool 32 is aligned with the height of the center of the workpiece. Of course, the turning tool 32 can be adjusted to an intended height relative to the center of the workpiece as needed for processing. The method of adjusting the height of the turning tool 42 to adjust the height of the turning tool 32 is very convenient to implement and operate, and the height of the turning tool 32 can be finely adjusted to make the relative position of the turning tool 31 and the center of the workpiece as close as possible. Inside. Although the present case is illustrated by a preferred embodiment, those skilled in the art can make various forms of change without departing from the spirit and scope of the case. The above embodiments are only used to illustrate the case, and non-M325184 is used to limit the case. The track is still a miscellaneous god of the county _ miscellaneous changes or changes to apply for patent scope.
