Description

SENSING ELEMENT POSITION ADJUSTMENT SYSTEM

Field of the Invention

The present invention relates to a position adjustment system that enables remote adjustment of the position of the sensing element that enables the workpiece to be sensed in a system where processing is performed on the workpiece.

State of the Art

A lathe chuck, which ensures that the workpiece is held firmly during the process and thus helps in machining, is used in systems such as the CNC lathe, which provides the process of turning the workpiece by turning the same after cutting. There are usually two proximity sensors as sensing element in the chuck puller roller, which is connected with the chuck and helps to clamp the workpiece so as to keep the same stable. The main task of these sensors is to check the clamping state of the workpiece of the chuck and to determine that if the clamping is sufficient, there is no problem in the rotation of the chuck and starting the system. As long as the diameter value of the workpieces does not change during the operations, the position of these sensors is not required to change. However, if the workpiece to be processed has a different diameter value, the position setting of the relevant sensor must be re-adjusted due to the change in the final position of the chuck jaws. This adjustment process is performed manually by the user/operator by entering the lathe machine. Therefore, before each different diameter workpiece is processed, the user must enter the machine and re-adjust the sensor position by turning the nut on the proximity sensor with a wrench. This situation causes both the workload and the total processing time to increase and an unsafe operation for the user.

In a patent document numbered US 11117237B2, which is in the state of the art, a machine tool provided with spindle having measurement function is described. Said machine tool includes: a hollow spindle including a hollow portion along an axial direction; a plurality of chuck claws openably mounted at a distal end portion of the hollow spindle, and configured to hold a workpiece; an operation rod inserted into the hollow portion of the hollow spindle in a movable manner, and configured to close the plurality of chuck claws with movement of the operation rod toward one side in the axial direction and open the plurality of chuck claws with movement of the operation rod toward the other side in the axial direction; and a measuring apparatus that is configured to measure an opening dimension of the plurality of chuck claws based on a movement amount of the operation rod, can be a stroke sensor.

In the mentioned document, there is no mention of a solution for adjusting the position of the measuring device by remote control and preventing the user from entering the machine for position adjustment.

As a result, in a system where processing is applied on the workpiece, especially the CNC lathe, there is a need to develop a position adjustment system that allows the detection of the clamping state of the workpiece and allowing the system to operate, allowing the physical position of the sensing or measuring element to be adjusted by remote control, thus preventing the user from needing to enter the system before applying any different workpieces.

Aim of the Invention

The present invention relates to a position adjustment system which fulfills the abovementioned requirements, eliminates all disadvantages and brings some additional advantages.

Another aim of the present invention is to obtain an effective and safe position adjustment system, which prevents the user/operator from entering the system and manually adjusting the position of the sensing/measurement element before applying any operation on different workpieces, and to increase the user's safety.

Another aim of the preseny invention is to obtain an efficient position adjustment system that reduces the workload and processing times during measurement with different workpieces. Another aim of the present invention is to obtain an effective position adjustment system that reduces user- induced errors and increases the accuracy of the measurement process.
