Description

Technical Field

[0001] This application relates to the technical field of automotive flange detection and fixation, and in particular, to an automotive flange detection and fixation device. Background Technique

[0002] A flange is also called a flange plate or a flange. A flange is a part that connects pipes to each other and to valves, and is connected to the pipe end. There are holes in the flange, and bolts are used to tightly connect the two flanges. Gaskets are used to seal between the flanges. Flanges are divided into threaded connection (screwed) flanges, welded flanges, and ferrule flanges. A flange connection or a flange joint refers to a detachable connection composed of a flange, a gasket, and bolts connected to each other as a set of combined sealing structures. Flanges are always used in pairs. Threaded flanges can be used for low-pressure pipelines, and welded flanges are used for pressures above four kilograms. A sealing gasket is added between the two flange plates, and then the bolts are tightened. Flanges of different pressures have different thicknesses, and the bolts they use are also different. When pumps and valves are connected to pipelines, the local parts of these equipment are also made into corresponding flange shapes, which are also called flange connections. Flange connections are convenient to use and can withstand relatively large pressures. In industrial pipelines, flange connections are widely used. The structure of existing automotive flanges is complex.

[0003] Before the existing automotive flanges leave the factory for use, their strength and shape need to be detected. During the detection process, the flanges need to be fixed. The existing flanges are generally clamped by tooling fixtures. This clamping method is generally carried out under the two sides of the flange. This clamping method may scratch the surface of the flange, affect the subsequent use of the flange, and reduce the safety during the flange detection process. Therefore, those skilled in the art have provided an automotive flange detection and fixation device to solve the problems raised in the above background technique. Utility Model Content

[0004] To solve the problems raised in the above background technique, this application provides an automotive flange detection and fixation device.

[0005] An automotive flange detection and fixation device provided by this application adopts the following technical solutions:

[0006] An automotive flange detection and fixation device includes a base, a fixing table is fixedly connected above the base, and a limiting table is fixedly connected above the fixing table;

[0007] There are two support rods. The two support rods slide inside the base. A threaded rod is rotatably inserted into the inside of the two support rods. One end of the two threaded rods is fixedly connected with a handrail;

[0008] A bidirectional lead screw is rotationally arranged inside the base. Both of the two support rods are threadedly sleeved on the surface of the bidirectional lead screw, and the two support rods slide in opposite directions.

[0009] A limiting component, which is provided with two groups, and the two groups of the limiting components are respectively arranged on the surfaces of the two threaded rods.

[0010] In some embodiments, a baffle is fixedly connected to one side of the limiting platform, a limiting plate is arranged on one side of the baffle, and the limiting plate slides on the upper surface of the limiting platform.

[0011] In some embodiments, two sliders are fixedly connected to the lower side of the limiting plate. The two sliders slide inside the limiting platform. One side of each of the two sliders is fixedly connected to a tension spring, and one end of each of the two tension springs is fixedly connected to the inner wall of the limiting platform.

[0012] In some embodiments, limiting blocks are fixedly connected to both sides of the two support rods. Two limiting chutes are symmetrically formed inside the base, and the two limiting blocks respectively slide on the inner walls of the two limiting chutes.

[0013] In some embodiments, the limiting component includes lifting blocks respectively threadedly sleeved on the surfaces of the two threaded rods. Guide rods are rotatably inserted into one side of each of the two lifting blocks. One end of each of the two guide rods is fixedly connected to a pressing block, and the two pressing blocks are respectively located on both sides above the limiting platform.

[0014] In some embodiments, limiting blocks are fixedly connected to both sides of the two lifting blocks. The two limiting blocks respectively slide in a fitting manner on the inner walls of the two support rods.

[0015] In summary, the present application includes the following beneficial technical effects:

[0016] (1) When a worker needs to detect an automotive flange, the worker will place it vertically above the limiting platform. The lower part of the flange will be in contact with the outer wall above the limiting platform. The worker rotates the bidirectional lead screw, and the rotation of the bidirectional lead screw drives the two support rods to slide inside the base. Then the worker rotates the two handrails respectively, and the two handrails drive the two threaded rods to rotate. During the rotation of the two threaded rods, the limiting component will descend. When the lower parts of the two limiting components come into contact with the upper part of the flange, the two limiting components and the limiting platform form a triangular structure, fixing the flange between the two limiting components and the limiting platform. In this way of fixing, by clamping the outer surface of the flange, scratching on both sides of the flange is reduced, and both outer surfaces of the flange are exposed on the outside, which is convenient for detecting the positioning holes of the flange and improves the detection efficiency.

[0017] (2) The inside of the lifting block is engaged with the threaded rod. The lifting block slides along the surface of the support rod. The lifting block drives the guide rod and the pressing block to lift and lower. When the lower sides of the two pressing blocks are in contact with the outer wall of the flange, the guide rod will rotate following the pressing block, increasing the stability of the contact between the outer wall of the pressing block and the outer wall of the flange. During the lifting and lowering process of the lifting block, both sides of the lifting block will be in contact with the inner wall of the support rod, and the limit clamping blocks on both sides of the lifting block will be inserted into the inside of the support rod to slide, increasing the contact area between the support rod and the lifting block, making it not easy to skew during the sliding process of the lifting block and increasing its stability.

Detailed Description of the Embodiment

[0023] The following is a further detailed description of the present application in combination with the attached Figures 1-4 drawings.

[0024] The embodiment of the present application discloses an automobile flange detection and fixing device. Referring to Figures 1-4 , an automobile flange detection and fixing device includes a base 1, a support rod 6, a bidirectional lead screw 7 and a limit component 8. A fixed table 2 is fixedly connected above the base 1, a limit table 3 is fixedly connected above the fixed table 2. There are two support rods 6, and the two support rods 6 are slidably located inside the base 1. A threaded rod 61 is rotatably inserted into the inside of the two support rods 6. One end of the two threaded rods 61 is fixedly connected with a handrail 62. The bidirectional lead screw 7 is rotatably arranged inside the base 1. The two support rods 6 are both threadedly sleeved on the surface of the bidirectional lead screw 7, and the two support rods 6 slide in opposite directions. There are two groups of limit components 8, and the two groups of limit components 8 are respectively arranged on the surfaces of the two threaded rods 61;

[0025] In the implementation process, when workers need to inspect the automotive flange, they will place it vertically above the limiting platform 3. The lower part of the flange will be in contact with the outer wall above the limiting platform 3. The worker rotates the bidirectional lead screw 7, and the rotation of the bidirectional lead screw 7 adjusts the sliding of the two support rods 6 inside the base 1. Then, the worker rotates the two handrails 62 respectively, and the two handrails 62 drive the two threaded rods 61 to rotate. During the rotation of the two threaded rods 61, the limiting component 8 will descend. When the lower parts of the two limiting components 8 come into contact with the upper part of the flange, the two limiting components 8 and the limiting platform 3 form a triangular structure, fixing the flange between the two limiting components 8 and the limiting platform 3. In this way of fixing, by clamping the outer surface of the flange, scratching on both sides of the flange is reduced, and both outer surfaces of the flange are exposed outside, facilitating the inspection of the positioning holes of the flange and improving the inspection efficiency.

[0026] Among them, a baffle 4 is fixedly connected to one side of the limiting platform 3, a limiting plate 5 is arranged on one side of the baffle 4, and the limiting plate 5 slides on the upper surface of the limiting platform 3. The baffle 4 and the limiting plate 5 have the same shape. When the worker places the flange above the limiting platform 3, the back of the flange will be in contact with one side of the baffle 4, and then another part of the flange will be in contact with the outer wall of the limiting plate 5, increasing the stability of the flange placed above the limiting platform 3.

[0027] Preferably, two sliders 51 are fixedly connected to the lower part of the limiting plate 5, and the two sliders 51 slide inside the limiting platform 3. One side of each of the two sliders 51 is fixedly connected to a tension spring 52, and one end of each of the two tension springs 52 is fixedly connected to the inner wall of the limiting platform 3. When the worker places the flange above the limiting platform 3 and between the baffle 4 and the limiting plate 5, there is a telescopic rod inside the tension spring 52, and the tension spring 52 pulls the limiting plate 5 to slide towards the direction close to the flange, increasing the stability of the contact between the limiting plate 5 and the outer wall of the flange.

[0028] Specifically, limiting blocks 63 are fixedly connected to both sides of the two support rods 6. Two limiting chutes 11 are symmetrically arranged inside the base 1, and the two limiting blocks 63 slide on the inner walls of the two limiting chutes 11 respectively. The limiting blocks 63 increase the contact area between the support rods 6 and the base 1, and the base 1 limits the sliding position of the limiting blocks 63 through the limiting chutes 11, increasing the stability of the sliding of the support rods 6 and the limiting blocks 63 inside the base 1.

[0029] More specifically, the limiting component 8 includes lifting blocks 81 respectively threadedly sleeved on the surfaces of the two threaded rods 61. One side of each of the two lifting blocks 81 is rotatably inserted with a guide rod 82, and one end of each of the two guide rods 82 is fixedly connected with a pressing block 83. The two pressing blocks 83 are respectively located on both sides above the limiting platform 3;

[0030] The inside of the lifting block 81 is engaged with the threaded rod 61. The lifting block 81 slides along the surface of the support rod 6. The lifting block 81 drives the guide rod 82 and the pressing block 83 to lift and lower. When the lower sides of the two pressing blocks 83 are in contact with the outer wall of the flange, the guide rod 82 will rotate following the pressing block 83, increasing the stability of the contact between the outer wall of the pressing block 83 and the outer wall of the flange.

[0031] Further, in the implementation process, limiting blocks 84 are fixedly connected to both sides of the two lifting blocks 81. The two limiting blocks 84 respectively slide in contact with the inner walls of the two support rods 6. During the lifting process of the lifting block 81, both sides of the lifting block 81 will be in contact with the inner walls of the support rods 6. The limiting blocks 84 on both sides of the lifting block 81 will be embedded in the support rods 6 and slide, increasing the contact area between the support rods 6 and the lifting block 81, making it difficult for the lifting block 81 to skew during the sliding process and increasing its stability.

[0032] The implementation principle of an automobile flange detection and fixing device according to an embodiment of the present application is as follows: When a worker needs to detect an automobile flange, the worker will place it vertically above the limiting platform 3. The lower part of the flange will be in contact with the upper outer wall of the limiting platform 3. The worker rotates the bidirectional lead screw 7. The rotation of the bidirectional lead screw 7 adjusts the two support rods 6 to slide inside the base 1. Then the worker rotates the two handrails 62 respectively. The two handrails 62 drive the two threaded rods 61 to rotate. During the rotation of the two threaded rods 61, the limiting assembly 8 will descend. When the lower parts of the two limiting assemblies 8 come into contact with the upper part of the flange, the two limiting assemblies 8 and the limiting platform 3 form a triangular structure, fixing the flange between the two limiting assemblies 8 and the limiting platform 3. In this way of fixing, by clamping the outer surface of the flange, scratching of the two side surfaces of the flange is reduced, and the two outer side surfaces of the flange are both exposed outside, facilitating the detection of the positioning holes of the flange and improving the detection efficiency.
