Description

Technical Field

[0001] This utility model belongs to the field of laser inspection tooling technology, specifically relating to a long strip clamping tooling for laser inspection instruments. Background Technology

[0002] Laser inspection fixtures are precision measurement and inspection devices based on laser technology, widely used in industrial manufacturing, automated production, and quality control. They utilize the high directionality, monochromaticity, and coherence of lasers to achieve non-contact, high-precision (typically micrometer-level) measurement and inspection functions. Common types include laser ranging fixtures, laser centering fixtures, laser contour scanning fixtures, and laser mark detection fixtures, each suitable for different scenarios such as distance measurement, mechanical axis centering, surface contour scanning, and mark recognition.

[0003] There is a long strip workpiece that needs to have its hole spacing, hole diameter and flatness inspected on one side. Due to its long size, the inspection instrument needs to scan back and forth on the inspection surface of the workpiece, which takes a long time. However, due to its narrow width, the inspection instrument has an excessive inspection range in the width direction, which makes it unable to fully utilize the inspection instrument and affects efficiency.

[0004] One existing inspection fixture has a fixed clamping plate on one side of a long strip, and a horizontally moving clamping plate on the other side via a cylinder. If two fixtures are arranged symmetrically, the size is too large to be placed in the inspection area of ​​the laser detector.

[0005] To address the aforementioned issues, this application proposes a long strip clamping fixture for laser detectors. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, this utility model provides a long strip clamping fixture for laser detectors, which is characterized by its small size, compact structure, and ease of use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamping fixture for a long strip of a laser detector, comprising a fixed base, on which multiple clamping mechanisms are provided along the length of the long strip. Each clamping mechanism includes two first elevation blocks symmetrically fixed to the fixed base and a placement plate mounted on the upper ends of the two first elevation blocks. Symmetrical fixed clamping plates are provided on both sides of the upper end of the placement plate. A second elevation block is fixed in the middle of the upper end of the placement plate. A symmetrically sliding inclined platform is provided on the second elevation block. A movable clamping plate, which cooperates with the fixed clamping plates to clamp the long strip, is fixed to the outer side of the inclined platform. An equilateral trapezoid is provided between the two inclined platforms. A clamping cylinder, with its output end penetrating the second elevation block and fixedly connected to the equilateral trapezoid by a long screw, is provided on the fixed base via a cylinder slot. When the clamping cylinder pushes upward, the movable clamping plate disengages from the fixed clamping plate through the equilateral trapezoid and the inclined platform. A lifting positioning strip is provided at the end of the clamping mechanism near the outlet end of the long strip.

[0008] As a preferred technical solution of this utility model, the second shim block is fixed to the placement plate by bolts and has a groove at its upper end for horizontal sliding of the two inclined platforms.

[0009] As a preferred technical solution of this utility model, symmetrical U-shaped strips are fixed on the inclined surface of the inclined platform, and U-shaped grooves are provided on both inclined surfaces of the equilateral trapezoid to slide with the U-shaped strips.

[0010] As a preferred technical solution of this utility model, the long screw is fixedly connected to the equilateral trapezoid and the output end of the clamping cylinder, and the long screw also slides through the second shim block.

[0011] As a preferred technical solution of this utility model, the clamping mechanism has a slot for the positioning bar to move along the vertical direction on the placement plate of the positioning bar, and a positioning cylinder with the exhalation end fixed to the positioning bar is fixed in the cylinder slot.

[0012] As a preferred embodiment of this utility model, the length of the positioning strip is greater than the length between the two symmetrically arranged clamping plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are: two long strips can be placed on the placement plate at the same time, and then the clamping cylinder is placed in the middle of the lower part of the placement plate. When the clamping cylinder is activated, it can drive the two inclined platforms on the inner side to move synchronously to clamp the two long strips, reducing the space occupied; the positioning strip and positioning cylinder set on one side can facilitate the rapid positioning of the long strips on the production line, ensuring the clamping accuracy on the tooling, and facilitating the continued feeding after inspection.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1 - Figure 6This utility model provides the following technical solution: a clamping fixture for a long strip of a laser detector, comprising a fixed base 1 bolted to the detection area of ​​the detector, a fixed base 1 having multiple clamping mechanisms along the length of the long strip, the clamping mechanisms including two first raising blocks 2 symmetrically fixed to the fixed base 1 and a placement plate 3 mounted on the upper ends of the two first raising blocks 2, both the first raising blocks 2 and the placement plate 3 being bolted to the fixed base 1, symmetrical fixed clamping plates 4 being bolted to the upper sides of the placement plate 3, a second raising block 5 being bolted to the middle of the upper end of the placement plate 3, the second raising block 5 having symmetrically sliding inclined platforms 6, and a movable clamping plate fixed to the outside of the inclined platform 6, which cooperates with the fixed clamping plates 4 to clamp the long strip. 7. An equilateral trapezoid 8 is provided between the two inclined platforms 6. A clamping cylinder 9 is provided on the fixed base 1 through the cylinder groove 101, with its output end passing through the second shim block 5 and fixedly connected to the equilateral trapezoid 8 by a long screw 10. When the clamping cylinder 9 is pushed up, the equilateral trapezoid 8 and the inclined platform 6 drive the moving clamping plate 7 to disengage from the fixed clamping plate 4 and release it from the clamping of the long strip. The clamping mechanism end near the outlet end of the long strip is provided with a lifting positioning bar 11. The positioning bar 11 is perpendicular to the fixed clamping plate 4. This fixture can clamp two long strips at the same time. The inclined platforms on both sides are driven to move synchronously by the central cylinder to achieve compact clamping. The positioning bar and cylinder are used on one side to ensure rapid positioning and accuracy, which facilitates continued feeding after inspection and improves the efficiency of the production line.

[0025] Specifically, the second shim block 5 is fixed to the placement plate 3 by bolts and has a groove 501 at its upper end for horizontal sliding of the two inclined platforms 6. The groove 501 improves the stability of the inclined platform 6, thereby ensuring the reliability of the clamping of the moving clamping plate 7.

[0026] Specifically, symmetrical U-shaped bars 601 are fixed on the inclined surface of the inclined platform 6, and U-shaped grooves 801 are provided on both inclined surfaces of the equilateral trapezoid 8 to slide with the U-shaped bars 601. The U-shaped grooves 801 and U-shaped bars 601 ensure the transmission effect between the inclined platform 6 and the equilateral trapezoid 8.

[0027] Specifically, the long screw 10 is fixedly connected to the equilateral trapezoid 8 and the output end of the clamping cylinder 9. The long screw 10 drives the equilateral trapezoid 8 and the clamping cylinder 9 to rise and fall synchronously. A through hole for the long screw 10 to slide is provided in the second shim block 5.

[0028] Specifically, in order to ensure the stability of the positioning strip 11, the clamping mechanism has a slot on the vertical direction of the placement plate 3 for the positioning strip 11 to move. A positioning cylinder 12 with the exhalation end fixed to the positioning strip 11 is fixed in the cylinder slot 101. After the positioning strip 11 rises, it does not completely leave the slot. After it falls, it is located in the slot and is lower than the upper surface of the placement plate 3.

[0029] Specifically, in order for the positioning strip 11 to reliably block the two long strips, the length of the positioning strip 11 is greater than the length between the two symmetrically arranged clamping plates 4, so as to avoid insufficient blocking and causing the long strips to tilt.

[0030] The working principle and usage process of this utility model are as follows: On the production line, the detector is set on the production line, and this fixture is installed in the detection area of ​​the detector via a fixing base 1. Figure 2 - Figure 3 As shown, the long strip flows in from the left and flows out from the right, with the positioning strip 11 and positioning cylinder 12 as shown in the figure located at the outflow end;

[0031] When the fixture is released, the clamping cylinder 9 is in the upward position, and the two moving clamping plates 7 in the middle approach each other. During the test, the positioning cylinder 12 drives the positioning strip 11 to protrude from the placement plate 3. Then the long strip flows into the fixture along the upper surface of the placement plate 3. The positioning strip 11 positions one end of the long strip. At this time, the clamping cylinder 9 moves down, and the clamping cylinder 9 drives the equilateral trapezoid 8 to move down. The equilateral trapezoid 8 drives the inclined platforms 6 at both ends to move outward at the same time through the U-shaped groove 801 and the U-shaped strip 601. The inclined platforms 6 drive the moving clamping plates 7 to move and cooperate with the fixed clamping plates 4 to clamp the long strip from both sides. Then, the tester is used for testing.

[0032] After the inspection is passed, the positioning cylinder 12 drives the positioning strip 11 to move down, and the clamping cylinder 9 pushes up to release the long strip plate, and the inspected long strip plate flows out of the tooling.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
