Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a metal stamping calibration device. Background Technology

[0002] In the metal stamping process, the dimensional accuracy and positional accuracy of stamped parts directly affect product quality and subsequent processing. Therefore, calibration equipment is often needed to calibrate the position of workpieces or dies during the metal stamping process. In the field of metal stamping, the performance of calibration equipment directly affects the dimensional accuracy, geometric tolerances and production efficiency of stamped parts.

[0003] However, current metal stamping calibration devices typically have the following problems:

[0004] The probe position adjustment of existing calibration devices mostly relies on manual operation, such as moving it horizontally or vertically by using knobs or lead screws. This method is not only inefficient, but also difficult to achieve high-precision positioning. For stamped parts with complex shapes, it is often necessary to repeatedly adjust multiple components, which is time-consuming and labor-intensive. In addition, the calibration probes of traditional devices are usually fixed and cannot be adaptively adjusted according to the curvature or special angle of the stamped part, resulting in limited calibration coverage and easy omission of key detection points.

[0005] Secondly, many calibration devices lack automated drive mechanisms. Adjusting the arm spacing and moving the movable seat all require manual operation, making it difficult to integrate with automated production lines. In mass production, frequent manual intervention not only reduces production efficiency but may also affect the consistency of calibration results due to human error. In addition, the structural design of traditional devices is often designed for stamped parts of specific sizes. When product specifications change, the entire set of fixtures or calibration components need to be replaced, resulting in a serious lack of flexibility and adaptability of the equipment.

[0006] Therefore, how to provide a metal stamping calibration device that can achieve multi-dimensional precise adjustment, high degree of automation and stable structure is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] One objective of this invention is to provide a metal stamping calibration device. This invention can achieve high-precision calibration of metal stamping parts through a multi-dimensional automated adjustment structure and low-friction motion design, solving the problems of inconvenient adjustment, low precision, and poor adaptability of traditional devices.

[0008] A metal stamping calibration device according to an embodiment of the present invention includes a support, a support arm, and a movable seat;

[0009] The support has a first sliding groove through it, and the rear side of the support arm has a slider integrally formed. The slider is slidably installed in the first sliding groove. Both sets of support arms are symmetrically installed on the front side of the support through the slider. The two sets of support arms have a second sliding groove through them. The movable seat has a first calibration probe embedded in it. The first calibration probe passes through the second sliding groove.

[0010] Two sets of support arms are symmetrically equipped with lead screw seats at both ends of their outer walls. A first lead screw is rotatably installed in the lead screw seat. A first screw hole is opened through the upper part of the movable seat. The first lead screw passes through the first screw hole and the threads are engaged with each other.

[0011] An electric push rod is fixedly installed on the top of the movable seat. An adjustment rod is detachably installed on the top of the electric push rod. A second calibration probe is vertically embedded at one end of the adjustment rod.

[0012] Furthermore, a second lead screw is rotatably installed in the first slide groove. The outer walls on both sides of the second lead screw are provided with threads of opposite directions. The slider is provided with a second threaded hole that cooperates with the second lead screw. The rotation of the second lead screw drives the two sets of support arms to move synchronously towards or away from each other.

[0013] Furthermore, a first servo motor is fixedly installed on one side of the outer wall of the support, and the output shaft of the first servo motor is connected to the second lead screw to drive the second lead screw to rotate.

[0014] Furthermore, a second servo motor is fixedly installed at the front end of the support arm. The output shaft of the second servo motor is connected to the first lead screw for driving the first lead screw to rotate in order to adjust the longitudinal position of the movable seat.

[0015] Furthermore, a screw is fixedly installed on the top of the electric push rod, and a through hole is provided on the adjusting rod for the screw to pass through. One end of the screw that passes through the through hole is fixedly connected to the adjusting rod by a fastening nut, so as to realize the adjustable angle installation of the adjusting rod.

[0016] Furthermore, rollers are movably embedded on both sides of the bottom of the support arm, which can reduce friction when the support arm moves laterally.

[0017] Furthermore, bearings are provided at both ends of the first slide groove and inside the lead screw seat. The second lead screw and the first lead screw are rotatably mounted in the first slide groove and the lead screw seat respectively through two sets of bearings.

[0018] The beneficial effects of this utility model are:

[0019] This invention enables high-precision longitudinal movement within the second slide groove of the support arm via a movable seat driven by a first lead screw and a second servo motor. Combined with a first calibration probe, it allows for precise vertical calibration of the stamped part. Simultaneously, the combination of an electric push rod and an adjustable rod allows the second calibration probe to be finely adjusted in height via the electric push rod, and the detection angle can be adjusted via the screw and fastening nut, meeting the calibration requirements of complex curved surfaces or multiple angles and significantly expanding the applicability of the device.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] refer to Figure 1-4 A metal stamping calibration device includes a support 1, a support arm 3 and a movable seat 8;

[0028] The support 1 has a through groove 2, which guides the sliding of the support arm 3. The support arm 3 has an integrally formed slider 16 on the rear side, which is adapted to the first groove 2 and is slidably installed in the first groove 2. The two sets of support arms 3 are symmetrically installed on the front side of the support 1 through the slider 16, so that the support arms 3 can move laterally on the support 1 stably.

[0029] A second lead screw 14 is rotatably mounted in the first slide groove 2. The outer walls of the second lead screw 14 are provided with threads of opposite directions. The slider 16 is provided with a second threaded hole 17 that mates with the second lead screw 14. When the second lead screw 14 rotates, the two sets of support arms 3 can be driven to move synchronously towards or away from each other because the threads on both sides rotate in opposite directions. In order to realize the rotation of the second lead screw 14, a first servo motor 15 is fixedly mounted on the outer wall of one side of the support 1. The output shaft of the first servo motor 15 is connected to the second lead screw 14 for transmission. The rotation direction of the second lead screw 14 is controlled by the forward and reverse rotation of the first servo motor 15, thereby realizing the lateral movement adjustment of the support arm 3.

[0030] It should be noted that, in order to reduce the friction when the second lead screw 14 rotates, bearings are provided at both ends of the first slide groove 2. The second lead screw 14 can be rotatably installed in the first slide groove 2 through these two sets of bearings. At the same time, in order to reduce the friction when the support arm 3 moves laterally, rollers 18 are movably embedded on both sides of the bottom of the support arm 3. The rollers 18 roll in contact with the surface of the support 1, making the movement of the support arm 3 smoother.

[0031] refer to Figure 1-4 The two sets of support arms 3 have a second sliding groove 4 through them. The movable seat 8 has a first calibration probe 9 through it. The first calibration probe 9 passes through the second sliding groove 4, which allows the movable seat 8 to move longitudinally along the second sliding groove 4 on the support arm 3.

[0032] Among them, two sets of support arms 3 are symmetrically installed with lead screw seats 5 at both ends of the outer wall. A first lead screw 6 is rotatably installed in the lead screw seat 5. A first screw hole 19 is opened through the upper part of the movable seat 8. The first lead screw 6 passes through the first screw hole 19 and the threads are meshed with each other. A second servo motor 7 is fixedly installed at the front end of the support arm 3. The output shaft of the second servo motor 7 is connected to the first lead screw 6 for transmission. When the second servo motor 7 works, it drives the first lead screw 6 to rotate. Since the first lead screw 6 is threadedly engaged with the first screw hole 19 on the movable seat 8, the longitudinal position adjustment of the movable seat 8 on the support arm 3 is realized.

[0033] Similarly, in order to reduce the friction when the first lead screw 6 rotates, a bearing is provided in the lead screw seat 5, through which the first lead screw 6 is rotatably mounted in the lead screw seat 5.

[0034] refer to Figure 1-4An electric push rod 10 is fixedly installed on the top of the movable seat 8. A screw 20 is fixedly installed on the top of the electric push rod 10. A through hole 13 is opened on the adjusting rod 11 for the screw 20 to pass through. One end of the screw 20 that passes through the through hole 13 is fixedly connected to the adjusting rod 11 by a fastening nut 21.

[0035] In this way, the angle of the adjusting rod 11 can be adjusted. When the angle of the adjusting rod 11 needs to be adjusted, simply loosen the fastening nut 21, rotate the adjusting rod 11 to the appropriate angle, and then tighten the fastening nut 21. The second calibration probe 12 is vertically embedded at one end of the adjusting rod 11 for calibration and detection of the metal stamping process.

[0036] Working principle: During the metal stamping calibration process, the lateral position of the support arm 3 needs to be adjusted according to the size of the stamped part and the calibration requirements. The first servo motor 15 is started. Assuming the first servo motor 15 rotates in the forward direction, its output shaft drives the second lead screw 14 to rotate in the forward direction. Since the threads on both sides of the second lead screw 14 rotate in opposite directions, the sliders 16 on both sides, driven by the second lead screw 14, will move synchronously towards each other along the first slide groove 2, thereby bringing the two sets of support arms 3 closer together. For example, when calibrating a smaller metal stamped part, the support arms 3 can be adjusted to a suitable distance in this way. Conversely, if the first servo motor 15 rotates in the forward direction, the second servo motor 15 rotates in the forward direction, causing the two sets of support arms 3 to move closer together. When the first servo motor 15 rotates in the opposite direction, the second lead screw 14 also rotates in the opposite direction. The slider 16 will move synchronously in opposite directions along the first slide groove 2, and the two sets of support arms 3 will move away from each other. For example, for larger metal stamping parts, the support arms 3 can be adjusted to a suitable distance to meet the calibration requirements of stamping parts of different sizes. After the lateral position of the support arms 3 is adjusted, the longitudinal position of the movable seat 8 needs to be adjusted. The second servo motor 7 is started. If the second servo motor 7 rotates in the forward direction, its output shaft drives the first lead screw 6 to rotate in the forward direction. Since the first lead screw 6 is threaded into the first screw hole 19 on the movable seat 8, the movable seat 8 will move along the first screw hole 19. The second slide 4 moves upward. For example, when the first calibration probe 9 needs to be near the upper surface of the stamping die for calibration, the position of the movable seat 8 can be adjusted in this way. If the second servo motor 7 rotates in the reverse direction, the first lead screw 6 rotates in the reverse direction, and the movable seat 8 will move downward along the second slide 4. For example, when the first calibration probe 9 needs to be near the lower surface of the stamping part for calibration, the movable seat 8 can be adjusted to a suitable longitudinal position. After the position of the movable seat 8 is adjusted, it may be necessary to adjust the angle and height of the adjusting rod 11. First, loosen the fastening nut 21 and manually rotate the adjusting rod 11 so that one end of it... The second calibration probe 12 is aligned with the position to be calibrated, and then the fixing nut 21 is tightened to fix the angle of the adjusting rod 11. Then, the height of the second calibration probe 12 is adjusted by controlling the extension and retraction of the electric push rod 10. When the electric push rod 10 extends, the adjusting rod 11 and the second calibration probe 12 on it move upward; when the electric push rod 10 retracts, the adjusting rod 11 and the second calibration probe 12 on it move downward. For example, when calibrating the side of the stamping die, the extension and retraction of the electric push rod 10 can be adjusted to keep the second calibration probe 12 at a suitable distance from the side of the die for accurate calibration testing.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
