Description

Machine tool workpiece clamping detection device

Technical Field

The utility model relates to a lathe work piece detects technical field, especially relates to a lathe work piece clamping detection device.

Background

When a factory processes a tiny cylindrical workpiece into a metal sheet, the workpiece is generally vertically arranged on the table top of a machine tool, then the end face of the workpiece is milled, as shown in fig. 1 and fig. 2 of the attached drawings of the specification, after the milling processing of the end face of the workpiece is completed, a small-sized cutting tool is lowered to the initial point of the first highest processing position of the workpiece, the cutting tool horizontally cuts a circle around the side face of the workpiece and returns to the initial point, the sheet is cut off from the workpiece and is transported away, then the cutting tool is adjusted to the next processing plane in the direction of a processing coordinate Z, and so on, another sheet is cut off from the workpiece by the cutting tool, the operation is circulated until the material is processed, and an operator controls the cutting tool to reset to the first highest processing position and then to change a new workpiece. In the machining process, after each slice is cut, an operator needs to collect the cut slices and check whether a machine tool controller prompts to change materials, and if so, the operator is allowed to change the materials.

However, sometimes, due to carelessness of an operator, the machine tool controller does not wait for the prompt of changing to a new material, and the operation of changing the new material is not fed back to the machine tool controller, so that the machining coordinate is not reset to the highest first machining position, and after a machining program is started, the cutter is collided to the workpiece because the cutter is lower than the correct cutting position, so that the workpiece, the spindle and the machine tool are damaged. In order to solve the problem, some manufacturers use a three-dimensional probe to detect whether the position of a workpiece is correct before machining every time, but the three-dimensional probe is expensive, and a dry battery is needed for power supply during operation, so that the overall use cost is high.

Detailed Description

As shown in fig. 3, an embodiment of the present invention provides a machine tool workpiece clamping detection device, which includes a machine tool table 1, a tool setting gauge 2, and a mounting seat 3. The machine tool table board is characterized in that a workpiece position 11 is arranged on the machine tool table board 1, the workpiece position 11 is used for placing a workpiece 100 to be machined, the mounting seat 3 is used for mounting a cutter, the mounting seat 3 can move above the machine tool table board 1 along the X, Y and Z axes of working coordinates, the mounting seat 3 can control the cutter to cut the workpiece 100, and the workpiece 100 is cut into a plurality of thin slices.

As shown in fig. 3 to 4, the tool setting gauge 2 is mounted on the machine tool table top 1, and when an object contacts the tool setting gauge 2, the tool setting gauge 2 sends a signal to a controller of the machine tool. Be connected with actuating mechanism on the mount pad 3, actuating mechanism can drive mount pad 3 is in 1 top translation of lathe mesa, also can drive mount pad 3 and go up and down or go up and down in tool setting appearance 2 department in work piece position 11, wherein actuating mechanism can be arm or lead screw slip table guide rail module. The mounting seat 3 is detachably provided with a detection tube 4, the detection tube 4 extends downwards along the vertical direction, wherein the detection tube 4 is generally made of a bendable tube not easy to rebound, such as a hollow aluminum tube or a copper tube, the diameter of the tube is close to that of a copper wire, and the tube can be easily bent and does not rebound. In the case where the mount 3 mounts the probe tube 4 and the workpiece 100 is placed on the workpiece site 11, the probe tube 4 is set to have a length capable of colliding with the workpiece 100 during translation from the reset height over the workpiece 100 and colliding with the workpiece 100 during translation from the non-reset height over the workpiece 100.

As shown in fig. 3-5, the probe tube 4 moves with the mounting base 3 and sequentially passes over the workpiece position 11 and the tool setting gauge 2, in actual use, the mounting base 3 is firstly provided with a tool for cutting the workpiece, after the mounting base 3 cuts the workpiece 100 into a plurality of thin slices, an operator puts a new workpiece 100 on the workpiece 11, and then replaces the tool with the probe tube 4, and the vertical distance from the bottom end of the probe tube 4 which is not collided to the top end of the tool setting gauge 2 is set as a. When the operator changes the machine tool controller to a new material after prompting, the machining coordinate of the mounting base 3 is reset to the highest first machining position, and the mounting base 3 is at the normal working height, the bottom end of the probe tube 4 is now higher than the workpiece 100, the probe tube 4 passes over the workpiece 100, and the probe tube 4 does not collide with the workpiece 100, the probe tube 4 is always kept in a vertically downwardly extended state, when the detection tube 4 passes through the tool setting gauge 2, the mounting seat 3 drives the detection tube 4 to move downwards by a distance A, at the moment, the detection tube 4 is contacted with the tool setting gauge 2, the tool setting gauge 2 sends a signal to a controller of the machine tool, the controller of the machine tool receives the signal and judges that the mounting seat 3 is in a normal position, the mounting seat 3 returns to the position of the operator when the probe tube 4 is installed before, the operator replaces the probe tube 4 with a tool, and the next round of cutting of the workpiece 100 is started.

When the machine tool controller is not prompted to change to a new material due to the carelessness of the operator, and the machining coordinate of the mounting seat 3 is not reset to the highest first machining position, when the mounting seat 3 is in an abnormal position, the bottom end of the detection tube 4 is lower than the top end of the workpiece 100, the mounting base 3 passes through the workpiece position 11, the probe tube 4 touches the workpiece 100, the probe tube 4 is bent by the reaction force of the workpiece 100, then the mounting seat 3 drives the probe tube 4 to leave the workpiece 100 and move above the tool setting gauge 2, when the probe tube 4 is located above the tool setting gauge 2, the mounting seat 3 drives the detection tube 4 to move downwards for a distance A, at the moment, because the detection tube 4 is in a bent state, the detecting tube 4 with tool setting appearance 2 is in the state of keeping apart mutually, tool setting appearance 2 can not detect there is the object contact. The machine tool controller does not receive a contact signal of the tool setting gauge 2, the machine tool controller judges that the mounting seat 3 is in an abnormal position, operation negligence exists for an operator, in this case, an alarm can be sent by an external alarm device to prompt the operator to adjust the mounting seat 3 and the machine tool, at the moment, the operator needs to reset the machining coordinate of the mounting seat 3 to the highest first machining position, the probe tube 4 is replaced by a tool, and the next round of cutting of the workpiece 100 is restarted. Whether the detection tube 4 is bent due to the fact that the workpiece 100 is touched or not is detected, whether the position of the mounting seat 3 is located at a normal height or not is determined, the situation that the mounting seat 3 or a machine tool is damaged due to improper operation of an operator is avoided, the detection tube 4 is low in cost, the new detection tube 4 can be replaced in time after the workpiece 100 is bent due to collision, and use cost is reduced compared with the use of a three-dimensional probe.

As shown in fig. 3 to 5, the mounting base 3 includes a main body 31 and a main shaft 32, the main shaft 32 is mounted at the bottom end of the main body 31, the probe tube 4 is detachably mounted on the main shaft 32, and the main body 31 controls the main shaft 32 to rotate.
