Embodiment

[0018] The present patent can be further clearly understood through the following specific embodiments, but they do not limit the present patent.

[0019] Embodiment 1: A multi-parameter detection device for aluminum profiles, comprising: two bases 1 arranged at intervals along the length direction of the workpiece 100 to be measured and at least two carriers 12 arranged at intervals between the two bases 1. The workpiece 100 mounted on the carrier 12 is located between the two bases 1. A movable plate 2 that can move along the length direction of the workpiece 100 to be measured is mounted on each of the two bases 1. A support seat 3 is mounted on each of the two movable plates 2 that can approach or move away from each other. The horizontal part 301 of the support seat 3 is movably mounted on the movable plate 2 and can move along the length direction of the workpiece 100 to be measured. A first displacement sensor 4 is arranged outside one end of the horizontal part 301 of the support seat 3 facing away from the workpiece 100 to be measured. The body part 41 of the first displacement sensor 4 is mounted on the movable plate 2. The sensing part 42 of the first displacement sensor 4 faces the horizontal part 301 of the corresponding support seat 3 and is used to sense the displacement amount of the support seat 3. At least one first elastic member 5 is arranged between the horizontal part 301 of the support seat 3 and the body part 41 of the corresponding first displacement sensor 4. When the first elastic member 5 is in a natural relaxed state, the distance between the horizontal part 301 of the support seat 3 and the sensing part 42 of the corresponding first displacement sensor 4 is the largest. The other end of the horizontal portion 301 of the support base 3 is formed with a vertically extending vertical portion 302. On the side of the vertical portion 302 facing the workpiece 100 to be measured, a detection plate 15 is provided at intervals. One surface of the detection plate 15 is used to contact the end face to be measured of the workpiece 100 to be measured. A sleeve 161 is vertically installed at the center of the other surface of the detection plate 15. The other end of the sleeve 161 connected to the detection plate 15 extends towards the vertical portion 302 of the support base 3 and a spherical groove 162 is formed inside it. A spherical portion 171 at one end of a connecting rod 17 is embedded in the spherical groove 162 and is in rotational contact with the inner wall of the spherical groove 162. The other end of the connecting rod 17 is installed on the vertical portion 302 of the support base 3. When the detection plate 15 is not in contact with the workpiece 100 to be measured, the vertical portion 302 and the detection plate 15 are parallel to each other. A second displacement sensor 18 is installed on the vertical portion 302. The sensing end of the second displacement sensor 18 faces the detection plate 15 and is used to sense the displacement generated by the detection plate 15; When detecting a standard workpiece, specifically: the two first cylinders are changed from the contracted state to the extended state. During this process, through the two connecting plates, the two movable plates are driven as a whole to move towards the standard workpiece, so that the two detection plates are respectively in contact with the end faces of the standard workpiece to be measured. After that, the two detection plates continue to move towards the middle so that the detection plates are in extrusion contact with the end faces of the standard workpiece to be measured. The rotatable detection plate can be in surface contact with the end face of the standard workpiece to be measured. The second displacement sensor senses the distance between it and the detection plate. The first displacement sensor and the second displacement sensor sense the distance between them and the detection plate, and indirectly characterize the magnitude of the rotation amplitude of the detection plate with this distance. For a standard workpiece that is parallel to the detection plate in the natural state, the detection plate does not rotate during the measurement process, that is, the value sensed by the second displacement sensor is zero. At the same time, the detection plate presses the vertical portion of the support plate, and the horizontal portion of the support plate moves towards the first displacement sensor, and each generates a displacement value that can be sensed by the displacement sensor.

[0020] An installation groove 121 for embedding the workpiece 100 to be measured is formed on the upper surface of each of the above-mentioned carriers 12, and the distance between the two inner walls of the installation groove 121 is greater than the width of the workpiece 100 to be measured. A second cylinder 14 is installed on the side surface of the carrier 12 and outside the installation groove 121. A push block 141 is installed on the piston rod of the second cylinder 14 that can expand and contract in the width direction of the workpiece 100 to be measured. The push block 141 is used to be in extrusion contact with the side surface of the workpiece 100 to be measured; In use, first measure the standard workpiece. Install the standard workpiece on the carrier seat and make it embed in the installation groove on the carrier seat. At this time, the standard workpiece is located between the detection plates of the two bases. Then, synchronously start the second cylinders on each carrier seat, so that the second cylinders are changed from the contracted state to the extended state. The push blocks on the piston rods of the second cylinders push the standard workpiece so that the surfaces on the same side of it are all in contact with an inner side wall of the corresponding installation groove, thereby ensuring the straightness of the standard workpiece in the length direction, that is, making the end faces at both ends of the standard workpiece parallel to the vertical parts of the extrusion seats and the fixed seats.

[0027] The body part 41 of the above-mentioned first displacement sensor 4 is installed on the upper surface of the movable plate 2 through a support block 9. One end of the first elastic member 5 is connected to the support block 9.

[0028] The above-mentioned workpiece 100 to be measured is an aluminum profile.

[0029] Embodiment 2: A multi-parameter detection device for aluminum profiles, comprising: two bases 1 arranged at intervals along the length direction of a workpiece 100 to be measured, and at least two carrier seats 12 arranged at intervals between the two bases 1. The workpiece 100 to be measured installed on the carrier seats 12 is located between the two bases 1. A movable plate 2 that can move along the length direction of the workpiece 100 to be measured is installed on each base 1. A support seat 3 is installed on each of the two movable plates 2 that can approach each other or move away from each other. The horizontal part 301 of the support seat 3 is movably installed on the movable plate 2 and can move along the length direction of the workpiece 100 to be measured. A first displacement sensor 4 is arranged on the outer side of one end of the horizontal part 301 of the support seat 3 facing away from the workpiece 100.

The sensing part 42 of the first displacement sensor 4 faces the horizontal part 301 of the corresponding support seat 3 and is used to sense the displacement amount of the support seat 3. At least one first elastic member 5 is arranged between the horizontal part 301 of the support seat 3 and the body part 41 of the corresponding first displacement sensor 4. When the first elastic member 5 is in a natural relaxed state, the distance between the horizontal part 301 of the support seat 3 and the sensing part 42 of the corresponding first displacement sensor 4 is the largest; The other end of the horizontal part 301 of the support seat 3 forms a vertical part 302 extending upward. A detection plate 15 is arranged at intervals on one side of the vertical part 302 facing the workpiece 100 to be measured. One surface of the detection plate 15 is used to contact the end face to be measured of the workpiece 100 to be measured. A sleeve 161 is vertically installed at the center of the other surface of the detection plate 15. The other end of the sleeve 161 connected to the detection plate 15 extends toward the vertical part 302 of the support seat 3 and a spherical groove 162 is formed inside it. A spherical part 171 at one end of a connecting rod 17 is embedded in the spherical groove 162 and is in rotatable contact with the inner wall of the spherical groove 162. The other end of the connecting rod 17 is installed on the vertical part 302 of the support seat 3. When the detection plate 15 is not in contact with the workpiece 100 to be measured, the vertical part 302 and the detection plate 15 are parallel to each other. A second displacement sensor 18 is installed on the vertical part 302. The sensing end of the second displacement sensor 18 faces the detection plate 15 and is used to sense the displacement amount generated by the detection plate 15; Next, the perpendicularity and length of the workpiece to be measured are detected in the same manner as the workpiece to be measured in sequence. The values sensed by the first displacement sensor and the second displacement sensor for each workpiece to be measured are obtained, and the value is compared with the zero value. If the difference between the two values exceeds the set threshold, the workpiece to be measured is judged as unqualified. In this way, the measurement of the length of the workpiece and the qualitative detection of the perpendicularity of the end face of the workpiece can be realized simultaneously, so as to screen out qualified products that meet the requirements for both length and end face perpendicularity, greatly improving the detection efficiency and not causing damage to the workpiece.

[0030] At least one second elastic member 191 is disposed on each side of the sleeve 161 between the detection plate 15 and the support plate 3.

[0031] Each of the above-mentioned second elastic members 191 is sleeved on a guide post 192. The other end of the guide post 192 connected to the detection plate 15 passes through the mounting through hole 11 opened on the vertical portion 302 of the support plate 3 and is in clearance fit with the inner wall of the mounting through hole 11.

[0035] The body portion 41 of the above-mentioned first displacement sensor 4 is mounted on the upper surface of the movable plate 2 through a support block 9. One end of the first elastic member 5 is connected to the support block 9.

[0036] The workpiece 100 to be measured is an aluminum profile.

[0037] The movable plate 2 and the upper surface of the base 1, and the horizontal portion 301 of the support base 3 and the upper surface of the movable plate 2 are both connected by at least one set of slide rails 61 and sliders 62 in cooperation.

[0038] The vertical portion 302 of the support base 3 extending upward from the end of the horizontal portion 301 of the support base 3 opposite to the first displacement sensor 4 is used to press the detection plate 15.

[0039] A first cylinder 7 is mounted on the side surface of the base 1. The piston rod of the first cylinder 7 is connected to the movable plate 2 through a connecting plate 8.

[0040] There are two first elastic members 5, which are respectively located on both sides of the sensing portion 42 of the first displacement sensor 4.

[0041] The working principle of the present invention is as follows: During use, first measure the standard workpiece. Install the standard workpiece on the carrier seat and make it embed in the installation groove on the carrier seat. At this time, the standard workpiece is located between the detection plates of the two bases. Then, synchronously start the second cylinders on each carrier seat, so that the second cylinders change from the contracted state to the extended state. The push blocks on the piston rods of the second cylinders push the standard workpiece so that the surfaces on the same side of it are in contact with an inner side wall of the corresponding installation groove, thereby ensuring the straightness of the standard workpiece in the length direction, that is, making the end faces at both ends of the standard workpiece parallel to the vertical parts of the extrusion seat and the fixed seat; When detecting the standard workpiece, specifically: change the two first cylinders from the contracted state to the extended state. During this process, drive the two movable plates as a whole to move towards the standard workpiece through the two connecting plates respectively, so that the two detection plates are in contact with the end faces of the to-be-detected ends of the standard workpiece. Then, the two detection plates continue to move towards the middle so that the detection plates are in extrusion contact with the end faces of the to-be-detected ends of the standard workpiece. The rotatable detection plate can be in surface contact with the end face of the to-be-detected end of the standard workpiece. The second displacement sensor senses the distance between it and the detection plate, and the first displacement sensor and the second displacement sensor sense the distance between them, and indirectly characterize the magnitude of the rotation amplitude of the detection plate with this distance. For the standard workpiece that remains parallel to the detection plate in the natural state, the detection plate does not rotate during the measurement process, that is, the value sensed by the second displacement sensor is zero. At the same time, the detection plate extrudes the vertical part of the support plate, and the horizontal part of the support plate moves towards the first displacement sensor, and each generates a displacement value that can be sensed by the displacement sensor; Next, then successively detect the perpendicularity and length of the to-be-detected workpieces in the same way as the to-be-detected workpieces, obtain the values sensed by the first displacement sensor and the second displacement sensor for each to-be-detected workpiece, and compare this value with the zero value. If the difference between the two values exceeds the set threshold, then judge the to-be-detected workpiece as unqualified. In this way, it is possible to simultaneously measure the length of the workpiece and qualitatively detect the perpendicularity of the workpiece end face, so as to screen out the qualified products whose length and end face perpendicularity both meet the requirements, greatly improving the detection efficiency and not causing damage to the workpiece.

[0042] When using the above aluminum profile multi-parameter detection equipment, it can simultaneously measure the length of the workpiece and qualitatively detect the perpendicularity of the workpiece end face, so as to screen out the qualified products whose length and end face perpendicularity both meet the requirements, greatly improving the detection efficiency and not causing damage to the workpiece.
