Description

Adjustable Lathe Tool Holder

technical field

The utility model relates to the field of lathe equipment, in particular to a tool rest, in particular to an adjustable lathe tool rest.

Background technique

The current lathe tool holders use spacers to adjust the height of the turning tool. Tool setting is a very important step in lathe processing. Inaccurate installation height of the turning tool will indirectly change the various geometric angles of the turning tool, thus It affects the quality of the cutting process, but it is not easy to get a good turning tool, and most of the lathes nowadays use shims to adjust the height of the turning tool, which is not accurate and time-consuming. As we all know, the height of the knife is combined by the accumulation of spacers, but the backing blade has specifications, and the spacers of each specification are certain, so it is difficult to use spacers to make the height of the turning tool equal to the central axis of the lathe Yes, we also have a deep understanding when actually installing the knife. The height of the knife tip is a little lower than the central axis, but the spacer on it is too high, and it cannot be aligned with the center at all. In addition, the spacer is superimposed. Wait for it to be done. When the turning tool clamps the nut on the tool holder, the gasket will be compressed, reducing the height of the tool tip, and during turning, the strong cutting force on the turning tool will cause the gasket to compress the tool tip and reduce it.

Using the traditional tool setting method, that is, adjusting the height of the turning tool through the combination of pad blades has disadvantages such as low efficiency, poor accuracy, and inconvenience, and the height of the turning tool installation will directly affect the processing quality and accuracy of the workpiece and the turning tool. The life of itself, now requires a device that quickly and accurately aligns the turning tool with the center of the workpiece without the need for a backing insert.

Utility model content

The utility model aims to solve the problems existing in the above-mentioned prior art, and provides an adjustable lathe tool rest, which solves the current problems of low tool setting efficiency and poor precision, and meets the needs of fast and accurate tool setting during processing.

The technical solution adopted by the utility model to solve the technical problems: this adjustable lathe tool holder includes a lower working block, a groove is arranged on the lower working block, a rotatable adjusting rod is arranged obliquely on the lower working block, and the adjusting rod Through the groove, the part of the adjustment rod located in the groove is a threaded connection part, the threaded connection part is connected with the adjustment block, the top of the lower working block is provided with an inclined surface, the inclination angle of the inclined surface is consistent with the inclination angle of the adjustment rod, and the inclined surface There is a tool fixing seat fitted therewith, the upper part of the adjustment block is fixed on the tool fixing seat, the side end of the tool fixing seat is provided with a tool slot for placing a turning tool, and the tool fixing seat is provided with a fixing screw for fixing the tool. After setting in this way, the traditional tool setting method of inserting the blade is abandoned, and the movement of the tool fixing seat is driven by the operation of the adjusting rod. Errors and variables. At this time, due to the inclined plane fit between the lower working block and the tool fixing seat, the tool fixing seat moves forward and backward by rotating the adjustment rod, so the forward and backward movement of the tool fixing seat achieves the purpose of increasing the height, thereby adjusting the car. The purpose of knife height greatly improves the efficiency of knife setting.

A rotating head is provided on the part of the adjusting rod protruding from the lower working block, and the surface of the rotating head is provided with stripes for increasing friction. The swivel head with stripes makes it easy to control the rotation of the adjustment lever and improve work efficiency.

A cover plate is fixed on the end surface of the lower working block close to the rotating head. The cover plate effectively prevents foreign matter and dust from entering the groove and affecting the operation of the adjusting rod.

There is a square groove on the tool fixing seat, and the upper part of the adjustment block is located in the square groove. There are screws on the tool fixing seat. surface. The square groove can effectively limit and fix the adjustment block. It is also more labor-saving when the adjustment block drives the tool holder, which reduces the pressure of the screw and increases the service life of the tool holder. The screw is lower than the upper surface of the joint to make the tool holder more stable and avoid Accidents occur because the tool holder is not clamped securely.

The beneficial effects of the utility model are: the structure of the utility model is reasonable and compact, and by changing the original manual adjustment of the knife into the control of the adjustment rod, there is no need to use the pad blade to adjust the height, only need to control the adjustment rod to control the height of the tool holder, which is different from the traditional Compared with the turning tool, it has the advantages of fast tool setting, no need to pad the blade, and protects the chuck, which is suitable for promotion.
