Description

Technical Field

[0001] The present invention relates to the field of measuring and machining technology, in particular to a measuring machine and an electrical machining production system thereof. Background Art

[0002] With the continuous development of industrialized production and the continuous innovation of intelligent technology, the production methods of enterprises have also undergone tremendous changes. The production process has been continuously evolving from manual production to intelligent and automated production. However, the automated production in existing technologies still generally suffers from excessive human intervention. The existing high-conductivity blade electromachining micro-hole intelligent production line is equipped with a measuring machine, which is used to automatically measure the three-dimensional surface of the tooling blade or formed electrode. However, due to the different structures of the tooling blade and the formed electrode, the tooling blade or formed electrode needs to be installed by converting the structure. In addition, most of the installation processes are relatively complicated and still require manual operation to clamp the tooling blade or formed electrode to the measuring machine. This inevitably complicates the clamping structure of the measuring machine and makes the operation time-consuming and labor-intensive.

[0003] For example, the four-jaw self-centering chuck in the prior art is called a manual four-jaw self-centering chuck for machine tools. It consists of a disc body, four small bevel teeth, and a pair of jaws. The four small bevel teeth are engaged with the coil wire, and the back of the coil wire has a flat thread structure, and the jaws are equally installed on the flat thread. When the small bevel teeth are turned with a wrench, the coil wire rotates, and the flat thread on its back causes the jaws to move toward or out of the center at the same time. Because the pitch of the flat rectangular thread on the coil wire is equal, the four jaws move the same distance, which has the effect of automatic centering. However, it cannot accurately position and clamp the tooling blades and forming electrodes clamped by the robot arm, and still requires manual operation, which makes the work process time-consuming and labor-intensive.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The purpose of the present invention is to provide a measuring machine and its electrical machining production system to solve the problems existing in the above-mentioned prior art. By setting a chuck mechanism, the chuck can be used to quickly complete the rapid positioning and clamping of the tooling blade and the forming electrode, and it is convenient for the robot to quickly clamp and disengage the tooling blade and the forming electrode, which greatly shortens the production cycle and thus improves production efficiency. It can reduce human intervention, improve production accuracy, and ensure product quality.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 8As shown, this embodiment provides a measuring machine, including a part placement table 29 and a laser sensor 30 for detecting the shape of a part. A chuck 1 for clamping various parts is provided on the part placement table 29. The chuck 1 includes a clamping surface 2, a positioning hole 4 provided on the clamping surface 2, and a plurality of clamping jaws 3 movable radially along the positioning hole 4. The clamping jaws 3 are evenly spaced around the outer periphery of the positioning hole 4, and the clamping jaws 3 are connected to a clamping jaw 3 driving mechanism for driving them to gather toward the positioning hole 4. The preferred chuck 1 adopts a pneumatic chuck 1 structure, and the corresponding clamping jaw 3 driving mechanism adopts a cylinder, etc. A track for supporting the movement of the clamping jaw 3 is provided on the clamping surface 2. The chuck 1 is equipped with a chuck mechanism 6. The chuck mechanism 6 includes an annular clamping groove 5 for clamping by a manipulator and located outside the positioning hole 4. One end of the annular clamping groove 5 is provided with a chuck section 7 inserted into the positioning hole 4, and the chuck section 7 is provided with a limit ring 8 abutting on the clamping surface 2 at a position close to the annular clamping groove 5, and the claw 3 abuts on the outer peripheral wall of the limit ring 8. Preferably, the inner wall of the claw 3 is adapted to the limit ring 8 so that the claw 3 can be fitted with the limit ring 8, and there is a gap between the claw 3 and the annular clamping groove 5 for the robot to insert. The other end of the annular clamping groove 5 is fixed on a tooling matched with various parts. Furthermore, a number of equally spaced protrusions are provided on the top of the claw 3, which abut on the limit ring 8 along the circumferential direction, thereby fully reducing the obstruction to the robot inserting the annular clamping groove 5. The laser sensor 30 is arranged close to the clamping surface 2, and its sensing probe is facing each part. The measuring machine 12 is also equipped with a computer and a PLC. The measuring program is manually debugged on the computer according to the part shape and the parts of interest. The master control system automatically loads the measuring program to the measuring machine 12 according to the type of part to be measured, and then automatically performs three-dimensional shape measurement on the part. The hole positions are redistributed according to the measured three-dimensional shape, and the processing coordinates and production processing codes are calculated.

[0034] First, by setting the positioning hole 4, the manipulator with the chuck mechanism 6 is moved to the positioning hole 4, and the chuck section 7 is quickly inserted into the positioning hole 4, and the limiting ring 8 connected to the chuck section 7 is abutted on the clamping surface to complete the positioning of the chuck mechanism 6 and the parts it carries, ensuring its stability in the subsequent clamping process. By moving the claw 3, it moves along the radial direction of the positioning hole 4 and evenly abuts on the outer peripheral wall of the limiting ring 8 along the circumferential direction, gradually clamping and fixing the chuck mechanism 6 to ensure the stability of the chuck mechanism 6 and the parts it carries when the chuck 1 is moved. Furthermore, since there is a gap between the clamping claw 3 and the annular clamping groove 5 for the robot to insert, the other end of the annular clamping groove 5 is fixed on the tooling that matches various parts, so that the robot will not be restricted by the clamping claw 3 when clamping the chuck mechanism 6 to move to the positioning hole 4, or when moving the chuck mechanism 6 out of the positioning hole 4, so that the robot can flexibly clamp the chuck mechanism 6 and move it, thereby greatly shortening the production cycle and improving production efficiency, which can not only reduce human intervention, but also improve production accuracy and ensure product quality.

[0035] Among them, the part placement table 29 is provided with a base 31 which is movably arranged along the X-axis direction, and the base 31 is equipped with a base 31 driving mechanism for driving it to move along the X-axis direction. Preferably, the base 31 driving mechanism adopts a screw structure, and a base 32 which is movably arranged along the Y-axis direction is provided on the base 31, and the base 32 is equipped with a base 32 driving mechanism for driving it to move along the Y-axis direction. Preferably, the base 32 driving mechanism adopts a screw structure, and the chuck 1 is rotatably connected to the base 32. The base 32 is provided with a chuck 1 driving mechanism for driving the chuck 1 to rotate. The rotation axis of the chuck 1 is perpendicular to the X-axis and the Y-axis. By moving the chuck 1 along the X-axis direction with the base 31, the distance between the laser sensor 30 and the part to be measured can be adjusted, and by moving the chuck 1 along the Y-axis direction with the base 32, the contour scanning of the top and right part of the part to be measured is realized. The chuck 1 is rotatably connected to the base 32 for rotating the part to be measured, so as to expand the measurement range of the part to be measured and improve the accuracy of detection.

[0036] In addition, a sensor placement platform is provided on one side of the part placement platform 29, and the laser sensor 30 is movably installed on the part placement platform 29 along the Z-axis direction. Preferably, the laser sensor 30 is installed on the sensor support seat 33, and the sensor placement platform is provided with a sensor track that extends vertically and slides with the sensor support seat 33, and the laser sensor 30 is equipped with a sensor driving mechanism for driving it to move along the Z-axis direction. On the one hand, the laser sensor 30 is moved along the Z-axis direction and set on the sensor placement platform to adjust the height of the laser sensor 30 and the measured part to realize scanning of the entire structure of the measured part. On the other hand, by setting the laser sensor 30 on the sensor placement platform to separate it from the part placement platform 29, the laser sensor 30 only forms a movement on the Z-axis, reducing the setting of cables and avoiding the vibration of the laser sensor 30 when the base 31 on the part placement platform 29 moves.

[0037] Furthermore, the original equipment uses point laser to detect a total of 800 points of the part shape. The distance between points is large. Each time it moves to each measurement point, it needs to stop and then trigger the laser to collect data. This requires at least 800 moves. The trajectory program is also complicated, and the measurement data points are few. It cannot restore the actual shape of the part to a high degree. Then, the laser sensor 30 uses a line laser displacement sensor. The width range of the line laser displacement sensor is 30 to 39 mm. The laser it emits is composed of 3200 points. The interval between each point is 0.0125 mm, so as to fully increase the measurement data points and restore the actual shape of the part to a high degree.

[0038] As a preferred line laser sensor 30, an incremental encoder trigger is used, and a pulse signal input to the encoder signal input terminal is accepted as a trigger. The pulse signal is the signal output by the incremental encoder. The incremental encoder triggers the collection of the contour of the part according to the moving distance of the part. The structure is simple and easy to implement, and the signal transmission distance is long and the reliability is high.

[0039] Moreover, the incremental encoder triggers the collection of the contour of the part according to the distance the part moves along the Y-axis (screw structure). The servo mechanism of the Y-axis (screw structure) is equipped with a grating scale and forms a full closed-loop mode with the servo mechanism. The servo mechanism has its own pulse output port. The pulse position output in the full closed-loop mode is the actual position of the grating scale. The pulse output port of the servo driver of the servo mechanism is connected to the line laser controller of the line laser sensor 30. The line laser controller is matched with the Y-axis and together triggers the collection of the contour of the part at the required fixed interval, further ensuring the accuracy of restoring the actual shape of the part.

[0040] As a preferred embodiment of the present invention, the number of refinement points set in the line laser controller is 25. Every 25 pulses trigger the acquisition of a part's contour, and continuous scanning is performed to fully improve measurement efficiency. Specifically, the servo driver outputs a pulse indicating that the Y-axis (screw structure) has stepped 0.001mm. The number of refinement points set in the line laser controller is 25, which means that every 25 pulses of 0.025mm trigger the acquisition of a contour, and the scanning is continuous. There is no need to stop to trigger the acquisition, and only the part needs to be scanned in several parts. The program trajectory is reduced from 800 points to 9 parts. Since the line laser sensor 30 forms a closed loop with the motion control system, the grating scale pulse of the motion control system's Y axis is fed back to the line laser controller. The pulse output is 2500 pulses in AB phase 4-times frequency mode, which means that the Y axis has 10,000 pulses per revolution. The Y axis lead screw has a 10mm pitch, so the stroke of one pulse is 1μm. The subdivision number is set to 25 in the line laser controller. The line laser controller triggers the line laser sensor 30 every time it collects 25 pulses. The distance between each contour is 0.025mm, and the line laser contour data interval is 0.025mm. Therefore, the collected data points are 0.025mm apart in the X and Y directions. In this way, the interval accuracy between points can restore the real object to a high degree. As shown in Table 1:

[0041]

[0042] Table 1

[0043] Furthermore, the existing CNC system of the measuring machine 12 was upgraded to support direct and rapid data reading from the line laser sensor 30. Using the line laser sensor's high-speed data communication commands, the currently measured contour data can be quickly output to the computer via the controller. The data transmitted to the computer can be processed simultaneously with the line laser sensor's 30 measurement. The data processing process is as follows: delete invalid points → splice the graphics → calculate the coordinates of each point. After splicing, the part contains 24,847,200 point data points, highly recreating the main contours of the part. Hole locations are then redistributed based on the positions of machining points and feature points.

[0044] Existing measurement data algorithms have been upgraded to support processing of millions of point cloud data. After the upgrade, the CMM 12 boasts repeatable positioning accuracy better than ±0.005mm, with a modeling time of <4 minutes and a total measurement time of <8 minutes. Compared to traditional contact measurement methods and point laser sensors, this significantly reduces workpiece inspection time and improves measurement accuracy and efficiency. The CMM 12 utilizes a Panason icA6B servo for its motion control and a KEYENCE high-precision 2D laser displacement sensor for its measurement. The control system utilizes an industrial computer, ensuring system stability and reliability without crashes. The industrial computer boasts 16GB of memory and 1TB of storage capacity, ensuring sufficient information and data storage and processing capabilities.

[0045] In addition to being able to scan the shape and appearance of parts, the measuring machine 12 also has a self-calibration function. By scanning the standard block, it calculates the deflection angle and Y-axis parallelism of the linear laser sensor 30. The standard block is designed based on the EROWA fixture, and the parallelism of the six faces is ≤0.01mm, and the verticality is ≤0.01mm.

[0046] The entire electrical machining production system completes the measurement of a certain side of the part through Y-axis movement, and then adjusts the spatial position of the part through the X-axis, Z-axis and C-axis. The three-dimensional data measurement of the part is completed in multiple cycles, realizing automatic measurement of the three-dimensional surface of the blade; the measured data is deleted, spliced ​​and calculated in sequence to generate a 3D point cloud model, and the hole positions are distributed according to the distance between the hole and the characteristic part on the part or the relative relationship with other holes. The intersection coordinates of the hole position and the 3D point cloud model are obtained to complete the adaptive planning of the hole position; the calculated intersection coordinates are saved as a coordinate file, and the coordinate file of the part is read by the master control system to calculate and generate a processing program and send it to the corresponding processing machine tool, adjust the processing process and complete the adaptive drilling.

[0047] Furthermore, an electromachining production system is provided, comprising a first ground rail and a second ground rail 13 extending in the same direction and butted at their ends. The first ground rail is symmetrically provided with a number of electric spark forming machines 9 along two sides perpendicular to its extension direction. The second ground rail 13 is symmetrically provided with a number of electric spark punching machines 15 along two sides perpendicular to its extension direction. A measuring machine 12 is provided between the electric spark punching machine 15 and the electric spark forming machine 9 on one side. The measuring machine 12 is used to detect the shape of parts. A part transfer area and an operating table 19 are provided between the electric spark punching machine 15 and the electric spark forming machine 9 on the other side. The operating table 19 has an embedded computer and display, and an emergency stop and reset control box is provided on the surface of the operating table 19. Next to the operating table 19, and with the measuring machine 12, the part transfer area, and the operating table 19 all located at the position where the first and second ground rails 13 are opposite each other, the first and second ground rails 13 are respectively movably provided with a first manipulator 10 and a second manipulator 14 for clamping tooling for various parts. The preferred first and second manipulators 10 and 14 are both equipped with finger cylinders and solenoid valve control boxes. The finger cylinders are connected to the solenoid valves via air pipes, enabling the grasping of part tooling 22. The manipulators are connected to the manipulator control cabinet via data and power cables. A programming handle for the manipulators is connected to the outside of the control cabinet. To ensure safety, a safety fence is installed on the outermost side of the entire electromachining production system.

[0048] The parts transfer area is located next to the operating table 19 and includes a spare conveyor belt 21, a finished product conveyor belt 20, a to-be-processed conveyor belt 18, a recovered electrode conveyor belt 16, and an electrode conveyor belt 17, which are sequentially arranged along the extension direction of the first and second ground rails 13. A transition conveyor belt 11 is provided between the parts transfer area and the first or second ground rail 13, and between the measuring machine 12 and the first or second ground rail 13. This forms a loading area or temporary storage area for different items. The first manipulator 10 and the second manipulator 14 are both rotatably provided with a clamp, and the two ends of the clamp are respectively provided with a finger cylinder for clamping the part tooling 22 and the electrode wire tooling 26. The finger cylinder is detachably connected to the clamping section of the clamping head mechanism 6. By rotating the clamp, different clamping tasks can be completed at different positions. The two fixtures are a first fixture 23 and a second fixture respectively installed on the first manipulator 10 and the second manipulator 14. An axial hole 24 for rotating with the first manipulator 10 is provided in the middle position of the first fixture 23, and a first finger cylinder 28 and a second finger cylinder 25 for clamping the part tooling 22 and the electrode wire tooling 26 are provided at both ends respectively.

An axial hole 24 for rotating with the second manipulator 14 is provided in the middle position of the second fixture, and a third finger cylinder and a fourth finger cylinder for clamping the part tooling 22 and the electrode wire tooling 26 are respectively provided at both ends.
