Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, and particularly relates to a detection fixture for metal profiles. Background Art

[0002] At present, after the aluminum alloy profiles are extruded, it is necessary to detect their contour dimensions, etc. During conventional detection, external scanners or three-coordinate measuring machines are usually used. However, these methods can basically only be used for laboratory detection. It is necessary to manually or mechanically transport the profiles to the laboratory. The waiting time for the detection results is relatively long. Moreover, due to the long transportation distance, when the cooling is insufficient, the profiles may deform during transportation, resulting in inaccurate detection results. In addition, there is a problem of long time consumption from submitting the samples for inspection to obtaining the detection results, making it difficult to obtain the contour dimension data of the profiles in all aspects on site in a timely manner, resulting in a lag in production feedback and possibly a higher defect rate.

Detailed implementation manners

[0036] To make the above - mentioned objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be described in detail below in conjunction with the accompanying drawings and specific implementation manners. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0037] In the description of the present utility model, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise specifically defined.

[0038] In the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0039] The preferred implementation manners of the present utility model will be described in detail below with reference to the accompanying drawings.

[0040] See Figures 1 to 9As shown in the figure, this example provides a detection fixture tooling for metal profiles. The detection fixture tooling includes a base workbench 1, and a first limiting mechanism 2, a second limiting mechanism 3, a third limiting mechanism 4, and a fourth limiting mechanism 5 which are respectively arranged on the base workbench 1. The first limiting mechanism 2 is used to support and limit the metal profile 9 from the bottom, the second limiting mechanism 3 is used to support and limit the metal profile 9 from the side, the third limiting mechanism 4 is used to limit the metal profile 9 in the horizontal direction, and the fourth limiting mechanism 5 is used to limit the metal profile 9 from top to bottom.

[0041] There are multiple second limiting mechanisms 3 which together enclose an accommodation space 6. The first limiting mechanism 2 is located below the accommodation space 6, and the third limiting mechanism 4 is located on the side of the accommodation space 6. The second limiting mechanism 3 includes an open state and a closed state, and the fourth limiting mechanism 5 includes a retracted state and a limiting state. When the second limiting mechanism 3 is in the open state, the accommodation space 6 has a first volume, the fourth limiting mechanism 5 is in the retracted state and has a part away from the accommodation space 6; when the second limiting mechanism 3 is in the closed state, the accommodation space 6 has a second volume, the fourth limiting mechanism 5 is in the limiting state and has a part close to the accommodation space 6, and the first volume is larger than the second volume.

[0042] The accommodation space 6 with a relatively large first volume can allow the metal profile 9 to freely enter and exit, while the accommodation space 6 with a relatively small second volume can prevent the metal profile 9 from freely entering and exiting; and the volume size of the accommodation space 6 can be adjusted by controlling the states of the second limiting mechanism 3 and other limiting mechanisms.

[0043] In this example, when the fourth limiting mechanism 5 is in the retracted state, the orthographic projection of the fourth limiting mechanism 5 is located outside the orthographic projection of the accommodation space 6; when the fourth limiting mechanism 5 is in the limiting state, a part of the orthographic projection of the fourth limiting mechanism 5 is located within the range of the orthographic projection of the accommodation space 6, which is beneficial to the convenience of the metal profile 9 entering and exiting the accommodation space 6 and at the same time increases the stability when limiting the metal profile 9.

[0044] The first limiting mechanism 2 includes a first base 21 and at least two positioning protrusions 22 formed on the first base 21. The orthographic projections of the at least two positioning protrusions 22 on the base workbench 1 do not overlap with each other; further, there are at least two first limiting mechanisms 2 which are arranged in sequence along the length direction of the accommodation space 6.

[0045] The second limiting mechanism 3 includes a first limiting component 31 and a second limiting component 32 which are oppositely arranged. The first limiting component 31 and the second limiting component 32 respectively include a second base 331, a sliding member 332 slidably arranged on the second base 331, and a clamp 333 installed on the sliding member 332. The sliding member 332 has a first position and a second position. When the second limiting mechanism 3 is in the open state, the sliding member 332 is located at the first position. When the second limiting mechanism 3 is in the closed state, the sliding member 332 is located at the second position. Among them, the clamps of the first limiting component 31 may be the same as or different from those of the second limiting component 32. Whether the clamps of the two limiting components are the same depends on whether the two sides of the outer contour of the metal profile are the same. If the outer contours of the two sides are the same, the clamp structures of the two limiting components are also the same. If the outer contours of the two sides are different, the clamp structure on the corresponding side is adjusted according to the specific shape of the outer contour to fit the outer contour shape and achieve close fitting support and limitation. Further, the first limiting component 31 and the second limiting component 32 respectively further include a locking component. The locking component includes a first locking pin 334, a first locking hole (not shown) formed on the sliding member 332, and a second locking hole 335 and a third locking hole 336 respectively formed on the second base 331. When the first locking pin 334 is respectively inserted into the first locking hole and the second locking hole 335, the sliding member 332 is located at the first position. When the first locking pin 334 is respectively inserted into the first locking hole and the third locking hole 336, the sliding member 332 is located at the second position.

[0046] The third limiting mechanism 4 includes a third base 41 provided on the base workbench 1 and formed with a through hole (not shown), a limiting rod 42 slidably arranged in the through hole and formed with a fourth locking hole 421, and a second locking pin 43 provided on the third base 41 and capable of moving. The limiting rod 42 includes a locked state and a free sliding state. When the second locking pin 43 is inserted into the fourth locking hole 421, the limiting rod 42 is in the locked state. When the second locking pin 43 disengages from the fourth locking hole 421, the limiting rod 42 is in the free sliding state. The extending direction of the second locking pin 43 intersects with the extending direction of the limiting rod 42, for example, they can be arranged perpendicular to each other.

[0047] The fourth limiting mechanism 5 includes a fourth base 51 disposed on the base workbench 1, a third locking pin 52 rotatably disposed on the fourth base 51, the third locking pin 52 includes a locking rod 521 extending in a first direction, and a locking cap 522 disposed at one end of the locking rod 521 and extending in a second direction, the first direction is different from the second direction, and the rotation axis of the third locking pin 52 is parallel to the length direction of the accommodation space 6. Further, the fourth limiting mechanism 5 also includes a rotating connection member 53, a latch (not shown) and a rotating handle 54, the rotating connection member 53 is rotatably disposed on the fourth base 51 (for example, the rotating connection member 53 can be rotatably disposed at the upper end of the fourth base 51 through a hinge, etc.), the third locking pin 52 and the rotating handle 54 are both disposed on the rotating connection member 53, a fifth locking hole 511 is formed on the fourth base 51, and a sixth locking hole 531 corresponding to the fifth locking hole 511 is formed on the rotating connection member 53, and the latch can be inserted into the fifth locking hole 511 and the sixth locking hole 531 respectively.

[0048] In this example, a plurality of second limiting mechanisms 3 extend along the length direction of the base workbench 1 .

[0049] The inspection tooling also includes a go / no-go gauge 7 and a lifting hanger 8 respectively arranged on the base workbench 1 . The go / no-go gauge 7 is arranged outside the accommodating space 6 . There are multiple lifting hangers 8 , which respectively extend along the width direction of the base workbench 1 .

[0050] The go and no-go gauge in this example is a type of gauge that can be purchased commercially and used as a measurement standard for inspecting large quantities of products. Currently, in actual production, it is very troublesome to measure large quantities of products one by one using measuring tools (such as vernier calipers, micrometers and other graduated measuring tools). Qualified products have a measurement range, and all products within this range are qualified. Go gauges and no-go gauges can be used for measurement.

[0051] The lifting hanger 8 in this example can be used as a point of application of a cable or other force of a lifting device. For example, a rope can be put on the lifting hanger. At least four of them can be provided, which are respectively located at the four corners of the base workbench, which is conducive to achieving stability and safety during lifting and facilitates the transportation of the inspection and testing tooling to the preset position for inspection.

[0052] See also Figures 1 to 9As shown, in this example, a plurality of second limiting mechanisms 3 are arranged along the length direction of the base workbench, for example, there are 5. Each second limiting mechanism 3 includes a first limiting component and a second limiting component arranged oppositely, and a gap is formed between them. And they jointly constitute a receiving space 6 in the length direction of the base workbench 1. At the same time, the third limiting mechanism 4 and the fourth limiting mechanism 5 are independently arranged side by side with the first limiting component 31 or the second limiting component 32, and the first limiting mechanism 2 is arranged in the middle of them. After the metal profile 9 is placed in, the first limiting mechanism 2 supports the metal profile 9 from the bottom and provides a certain limiting effect. The second limiting mechanism 3 clamps the metal profile 9 from both sides. The third limiting mechanism 4 limits the metal profile 9 from the side along the horizontal direction. The fourth limiting mechanism 5 applies a force from the top to realize the limitation of the metal profile 9 from the top;

[0053] The following further describes the limiting and / or supporting effects of the second limiting mechanism 3, the third limiting mechanism 4, and the fourth limiting mechanism 5 in different states:

[0054] See Figure 2 and Figure 6 As shown, it schematically shows the schematic diagrams of the second limiting mechanism in the open state and the closed state. Among them, Figure 2 is the open state. The sliding member 332 is located at the rear of the second base 331 and abuts against the rear limiting baffle 337. At this time, the first locking pin 334 is inserted into the second locking hole, and the third locking hole 336 is in the exposed state. Preferably, a slide rail can be arranged on the second base 331, and the sliding member 332 is slidably installed on the slide rail, which is beneficial to better guiding; Figure 6 is the closed state. The sliding member 332 is located at the front of the second base 331 and abuts against the front limiting baffle 337. At this time, the first locking pin 334 is inserted into the third locking hole, and the second locking hole 335 is in the exposed state. After the clamp 333 moves forward, the volume of the receiving space is reduced, and the clamp can realize the clamping limitation and support of the metal profile.

[0055] See Figure 3 and Figure 7 As shown, it schematically shows the schematic diagrams of the third limiting mechanism in different states. Among them, Figure 3 is the yielding state. At this time, the limiting rod 42 of the third limiting mechanism retracts backward, the second locking pin 43 is pulled up, and the fourth locking hole 421 is in the exposed state. Further, the second locking pin 43 can be a bolt, and the limiting rod 42 is locked or released by rotating up or down, so as to realize the fixing or free movement of the limiting rod 42, such as free sliding; Figure 7The limiting state is that the limiting rod 42 of the third limiting mechanism extends forward, and the second locking pin 43 is inserted into the fourth locking hole to fix the locking rod 42, which can form a metal profile as shown in FIG. Figure 9 The interference limit state shown in .

[0056] See also Figure 4 and Figure 8 As shown, it schematically shows the fourth limiting mechanism in different states, wherein: Figure 4 In the yielding state, the locking rod 521 extends in the vertical direction, the locking cap 522 extends in the horizontal direction, the rotating handle 54 extends in the horizontal direction, a part of the rotating connecting member 53 is away from the upper end of the fourth base 51, and the third locking pin 52 is disengaged from the fifth locking hole 511 and the sixth locking hole 531, thereby achieving yielding of the metal profile as a whole; Figure 8 In the limited position state, at this time, the locking rod 521 extends in the horizontal direction, the locking cap 522 extends in the vertical direction, the rotating handle 54 extends in the vertical direction, the rotating connecting member 53 is in contact with the upper end of the fourth base 51, and the third locking pin 52 is respectively inserted in the fifth locking hole 511 and the sixth locking hole 531, so as to limit the metal profile as a whole, and can form a metal profile as shown in FIG. Figure 9 The interference limit state shown in .

[0057] In summary, the utility model innovatively provides an improved metal profile inspection and inspection tooling, which realizes rapid positioning of metal profiles such as aluminum profiles through multi-point positioning and / or support. Specifically, the improved inspection and inspection tooling is provided with limiting mechanisms for the outer contours of the metal profiles, such as the bottom, sides, and top, and they are all integrated on the base workbench, which greatly reduces the space occupation and can be carried and used at the profile processing site, which is conducive to rapid detection and rapid acquisition of various aspects of the profile dimension data of the profile, etc., and is convenient for timely grasping the production status and timely feedback, and reducing the processing defect rate; in particular, in the inspection and inspection tooling of the utility model, multiple limiting mechanisms respectively have different states, and the metal profiles are limited and allowed to pass through respectively through the control of different states. The operation is simple and easy to implement, which is conducive to ensuring the stability of the workpiece during the profile detection process and reducing the negative impact on the profile, thereby ensuring the accuracy of the detection results.
