Description

Technical Field

[0001] This utility model relates to the field of automobile conveying equipment technology, and more specifically, to a skid-handled inspection device. Background Technology

[0002] Skids are used in automobile production lines for carrying and transporting car bodies. Many car models utilize skids for positioning and transporting car bodies during the transfer process. After a period of use, skids inevitably experience positional deviations or wear, causing issues such as car bodies not falling into place or jamming. Therefore, skids need to be inspected using gauges at regular intervals.

[0003] Currently, the market uses ground-fixed inspection fixtures, which need to be fixed to the ground, thus allowing only fixed locations for skid testing. When a skid malfunctions far from the fixture, it needs to be transported to the fixture for inspection. Therefore, existing technology has the following limitations:

[0004] 1. Large space occupation; it needs to be permanently installed on a ground base, occupying the effective production area of ​​the workshop.

[0005] 2. Poor inspection mobility; the skid must be moved to a fixed station for inspection, making it impossible to conduct real-time inspection next to the production line, thus resulting in a lag in feedback on quality issues.

[0006] 3. High maintenance costs; foundation settlement can cause inaccurate testing benchmarks, so ground-fixed gauges need to be self-calibrated frequently, and because they are fixed to the ground, it is difficult to replace mechanically worn parts.

[0007] 4. Limited applicability; a single inspection tooling is only suitable for specific types of workpieces and is difficult to adapt to flexible production line layout adjustments (such as the transformation and upgrading of automobile production lines). Utility Model Content

[0008] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0009] To at least partially solve the above problems, this utility model provides a skid-handled inspection device, comprising: a structural frame, at least one positioning mechanism, and at least one detection mechanism;

[0010] The structural frame is used to install the positioning and detection mechanisms;

[0011] The positioning mechanism, installed on the structural frame, is used for positioning between the structural frame and the skid;

[0012] The testing mechanism, located on the structural frame, is used to calibrate the fulcrum on the skid.

[0013] Preferably, the structural frame consists of at least two first rods and at least two second rods, with one end of the second rod connected to one of the first rods and the other end connected to the other first rod or the end of the other second rod; the positioning mechanism is located at the bottom of the first rod or the bottom of the second rod.

[0014] Preferably, the two first rods connected by the second rod are parallel to each other.

[0015] Preferably, the first rod is arranged along the length direction of the skid, and the second rod is arranged along the width direction of the skid.

[0016] Preferably, there are two first rods and four second rods. The two first rods are arranged in parallel, one end of the second rod is connected to one of the first rods, and the other end is connected to the other first rod. The four second rods are arranged in parallel with each other.

[0017] Preferably, the positioning mechanism consists of a positioning element, a connecting plate, and two third rods. The third rods are arranged vertically, with their tops connected to the bottom of the structural frame and their bottoms connected to the top of the connecting plate. The two third rods are parallel and connected to each other by the connecting plate. The connecting plate has a connecting hole, and the positioning element is connected to the skid through the connecting hole at the top of the connecting plate.

[0018] Preferably, the positioning component consists of a positioning pin and a support ring. A nut is provided on the top of the positioning pin. The positioning pin passes through the connecting hole and extends into the skid. The nut is located on the top of the connecting plate. The support ring is sleeved on the outside of the positioning pin and located below the connecting plate. The connecting plate is connected to the skid through the support ring.

[0019] Preferably, the positioning element further includes a limiting element, which is disposed at the bottom of the connecting plate.

[0020] Preferably, the detection mechanism is provided with at least one fourth rod, the bottom of which is connected to the top of the detection mechanism and the top of which is connected to the structural frame, and the detection mechanism is provided with positioning holes.

[0021] Preferably, it also includes a handheld mechanism, which is disposed on the structural frame.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] With the above-mentioned mechanism design, the structural frame can be disassembled when not in use, eliminating the need for permanent installation in a fixed location, thereby significantly reducing the workshop's footprint. Because it can be assembled on-site, all components of the structural frame can be replaced, greatly reducing the maintenance cost of the inspection tool.

[0024] Before use, construct the structural frame according to the vehicle model or the position of the support points on the skid, and adjust the positions of the positioning mechanism and the detection mechanism on the structural frame. Because the structural frame, positioning mechanism, and detection mechanism can all be assembled on-site, they can be assembled according to different skids or vehicle models, thus allowing the fixture to adapt to different vehicle designs and, consequently, to the layout adjustments of flexible production lines.

[0025] During use, the structural frame can be manually moved directly to the skid to be inspected. The aluminum alloy structural frame makes the whole structure lightweight, reducing the weight of manual handling. In addition, to facilitate manual handling, a hand-held mechanism can be set on the structural frame, thereby further improving the moving and inspecting capabilities of the instrument.

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0036] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0037] like Figures 1-7 As shown, this utility model provides a sled-handled inspection device, including: a structural frame 1, at least one positioning mechanism 2 and at least one detection mechanism 3;

[0038] Structural frame 1 is used to install positioning mechanism 2 and detection mechanism 3. The shape of structural frame 1 can be changed and adjusted according to skid 4 or vehicle structure. Structural frame 1 is usually made of aluminum alloy.

[0039] Positioning mechanism 2 is installed on structural frame 1 and is used for positioning between structural frame 1 and skid 4;

[0040] The testing mechanism 3 is set on the structural frame 1 and is used to calibrate the fulcrum on the skid 4.

[0041] There are usually two detection mechanisms 3, namely a front support detection mechanism and a rear support detection mechanism. The detection mechanisms are connected as a whole by the structural frame 1, so that the relative position between the two detection mechanisms 3 is fixed, thereby realizing the position detection of the support point on the skid 4.

[0042] It also includes a handheld mechanism 5, which is mounted on the structural frame 1.

[0043] The detection mechanism 3 is equipped with at least one fourth rod 31. The bottom of the fourth rod is connected to the top of the detection mechanism 3, and the top is connected to the structural frame 1. Depending on the vehicle model and the skid 4, some detection mechanisms 3 can be directly installed on the structural frame 1, such as... Figure 3 As shown, some testing mechanisms 3 need to be installed on the structural frame 1 via a fourth rod 31 as an extension rod, such as... Figure 2As shown, the fourth rod 31 can be made of aluminum alloy. Its connection to the structural frame 1 and the detection mechanism 3 can be achieved using screws and angle irons, enabling quick installation and ensuring sufficient strength at the connection point. The detection mechanism 3 is provided with positioning holes for calibrating the fulcrum on the skid 4, such as... Figure 2 and Figure 3 As shown, the fulcrum or the fulcrum on the skid 4 can pass through the positioning hole to determine whether the fulcrum has shifted.

[0044] The working principle and beneficial effects of the above technical solution: Through the above mechanism design, the structural frame 1 can be disassembled when not in use, without the need for permanent installation in a fixed place, thereby greatly reducing the workshop area occupied. Because it can be assembled on site, the components of the structural frame 1 can all be replaced, greatly reducing the maintenance cost of the inspection tool.

[0045] Before use, construct the structural frame 1 according to the vehicle model or the position of the support point on the skid 4, and adjust the positions of the positioning mechanism 2 and the detection mechanism 3 on the structural frame 1. Since the structural frame 1, positioning mechanism 2 and detection mechanism 3 can all be assembled on-site, the structural frame 1, positioning mechanism 2 and detection mechanism 3 can be assembled according to different skids 4 or vehicle models, so that the fixture can adapt to different vehicle designs, and thus adapt to the layout adjustment of flexible production lines.

[0046] During use, the structural frame 1 can be manually moved directly to the skid 4 to be inspected. The structural frame 1 is made of aluminum alloy, which can make the whole lightweight and reduce the weight of manual handling. At the same time, in order to facilitate manual handling, a hand-held mechanism 5 can be set on the structural frame 1, thereby further improving the moving and inspecting capabilities of the inspection tool.

[0047] Furthermore, the structural frame 1 consists of at least two first rods 11 and at least two second rods 12. One end of the second rod 12 is connected to one of the first rods 11, and the other end is connected to the other first rod 11, or to the end of the other second rod 12. Both the first rods 11 and the second rods 12 are made of aluminum alloy, and both the first rods 11 and the second rods 12 can be detachably connected by a combination of angle iron and screws.

[0048] As needed, the first rod 11 can be extended by connecting the ends of screws and angle iron, and the second rod 12 can also be extended by connecting the ends of screws and angle iron. This allows the first rod 11 and the second rod 12 to have the same length for easy assembly; the lengths can also be different to distinguish the installation positions (as in the following embodiments).

[0049] The first rod 11 and the second rod 12 can be arbitrarily combined according to the shape of the vehicle model or the skid 4, and the positioning mechanism 2 is located at the bottom of the first rod 11 or the bottom of the second rod 12.

[0050] Furthermore, the two first rods 11 connected by the second rod 12 are parallel to each other. Usually, the length of the first rod 11 is greater than the length of the second rod 12. The length of the first rod 11 should not be shorter than the distance between the two farthest support points on the skid 4. The parallel first rods 11 can serve as main rods, and the second rod 12 can serve as secondary rods between the main rods, serving to connect the two first rods 11 together. The second rods 12 can be parallel to each other, or they can cross in an X-shape, or they can connect between the two first rods 11 in a W-shape.

[0051] Furthermore, the first rod 11 is arranged along the length direction of the skid 4, and the second rod 12 is arranged along the width direction of the skid 4. This allows the structural frame 1 to form a regular rectangular frame, which is convenient for assembly and storage (it is not necessary to process the end face of the second rod 12 into a bevel).

[0052] Furthermore, as one of many embodiments, there are two first rods 11 and four second rods 12. The two first rods 11 are arranged in parallel, one end of each second rod 12 is connected to one of the first rods 11, and the other end is connected to the other first rod 11. The four second rods 12 are arranged in parallel to each other. Figure 6 As shown, this forms a stable rectangular frame structure.

[0053] Furthermore, the positioning mechanism 2 consists of a positioning element 21, a connecting plate 22, and two third rods 23. The third rods 23 are arranged vertically and are used to support the structural frame 1. The third rods 23 can be made of aluminum alloy. The top of the third rod 23 is connected to the bottom of the structural frame 1, and the bottom of the third rod 23 is connected to the top of the connecting plate 22. The two third rods 23 are parallel and connected to each other through the connecting plate 22. The connecting plate 22 is provided with a connecting hole. The positioning element 21 is connected to the skid 4 through the connecting hole at the top of the connecting plate 22, thereby realizing the positioning of the inspection tool on the skid 4.

[0054] Furthermore, as one of many embodiments, the positioning component 21 consists of a positioning pin 211 and a support ring 212. A nut is provided on the top of the positioning pin 211. The positioning pin 211 passes through the connecting hole and extends into the skid 4. The nut is located on the top of the connecting plate 22. The support ring 212 is sleeved on the outside of the positioning pin 211 and located below the connecting plate 22. The positioning pin 211 can be installed and fixed on the connecting plate 22 by means of the nut and the support ring 212. Since the nut rests on the top surface of the connecting plate 22, the distance of the positioning pin 211 extending below the connecting plate 22 can be adjusted by adjusting the position of the nut on the positioning pin 211. The support ring 212 is usually an elastic element, such as a rubber sleeve, used to fix the positioning pin 211 from below the connecting plate 22. When the connecting plate 22 is connected to the skid 4 through the support ring 212, the support ring 212 can not only play a supporting role but also a shock absorption role.

[0055] Furthermore, if only a single positioning element 21 is provided, the fixture is prone to shaking or rotation. Therefore, the number of positioning mechanisms 2 or positioning elements 21 is usually increased to improve the stability of the fixture. As one of many embodiments, without increasing the number of positioning mechanisms 2 or positioning elements 21, the positioning element 21 also includes a limiting element 24. The limiting element 24 is typically an n-shaped structure, such as... Figure 4 and Figure 5 As shown, the limiting member 24 is located at the bottom of the connecting plate 22. The limiting member 24 can be engaged with the truss or other structure of the skid 4, thereby assisting the positioning pin 211 in limiting its position. Typically, each connecting plate 22 has two limiting members 24, located below the two third rods 23 respectively, as shown. Figure 4 and Figure 5 As shown.
