Description

Technical Field

[0001] This utility model relates to the technical field of parts inspection equipment, specifically a clamping device for parts inspection. Background Technology

[0002] In industrial production, parts inspection is a crucial step in ensuring product quality. To accurately inspect parts, clamping devices are typically used to hold them in place so that the inspection equipment can stably measure various parameters of the parts.

[0003] In the parts inspection production process, it is necessary to clearly distinguish between inspected and uninspected parts for subsequent classification and management. However, most existing clamping devices for parts inspection only have simple clamping functions and lack the ability to mark and distinguish parts. At the same time, the surface of the chuck is usually covered with a rubber layer to protect the parts and increase friction. However, during long-term use, the rubber layer will gradually wear down or even be damaged due to frequent contact and friction with the parts. Since the chuck is integrated with the fixing structure, when the rubber layer has a problem, it is not possible to replace the rubber layer separately; the entire chuck must be replaced. Therefore, a clamping device for parts inspection is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device for parts inspection, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping device for part inspection, comprising an operating table, a sealing gasket fixed on the top of the operating table, a placement groove provided on the inner side of the sealing gasket, and a first part placed on the inner side of the placement groove;

[0006] A clamping assembly is provided on one side of the operating table, which is used to clamp and fix the first part to be inspected;

[0007] A marking component is provided on one side of the clamping assembly;

[0008] The marking assembly includes a connecting rod, one side of which is fixed with a metal post by bolts, and the metal post has a pointed tip at its bottom.

[0009] The clamping assembly includes a cylinder and two limiting frames. A rotating rod is hinged to one side of the limiting frame, a support rod is fixed to one end of the rotating rod, a pressure rod is fixed to one side of the support rod, a sleeve is provided on the outside of the pressure rod, and a rubber layer is fixed on the outside of the sleeve.

[0010] A push plate is fixed to the end of the cylinder push rod, and slide rods are fixed to both ends of the top of the push plate.

[0011] Preferably, the rotating rod has a groove on the side away from the rubber layer, and the sliding rod is slidably connected to the inner side of the groove.

[0012] Preferably, the connecting rod is fixed to one side of one of the support rods, the limiting frame is fixed to the top of the operating table, and the pressure rod is connected to the sleeve by bolts.

[0013] Preferably, the bottom of the operating table has two guide rods fixed, the bottom of the guide rods has a limit ring fixed, and one side of the push plate is slidably connected to the outside of the guide rods through a linear bearing.

[0014] Preferably, the bottom of the operating table is bolted to a base, and the cylinder is fixed to the bottom of the inner wall of the base.

[0015] Preferably, the top of the operating table is provided with an air hole, which is located inside the sealing gasket.

[0016] Preferably, as described above, a second part is welded to the top of the first part, and when the rubber layer contacts the top of the first part, the first part and the second part are in a state to be tested.

[0017] Preferably, the base has a through hole on one side, which is used for the air tube to pass through and communicate with the air hole.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0019] 1. Place the first part and the second part in the placement groove inside the sealing gasket on the top of the operating table. As the slide rod slides in the groove, it drives the rotating rod to rotate around the hinge point with the limit frame, thereby causing the support rod and the pressure rod to move synchronously. Finally, the rubber layer approaches and contacts the top of the first part, applying pressure to the first part to achieve stable and reliable clamping and fixing, ensuring that the first part and the second part will not move in the test state, and ensuring the accuracy of the test results.

[0020] Second, the pressure bar is connected to the sleeve by bolts, making it easier and faster to replace the sleeve and rubber layer. When the rubber layer is worn or damaged, a new sleeve can be replaced simply by removing the bolts, which reduces maintenance costs and time and improves the overall service life of the equipment.

[0021] Third, after the clamping assembly completes the clamping action, the support rod synchronously drives the connecting rod and the metal column to move towards the top of the first part, so that the tip of the bottom of the metal column contacts the first part and generates a dot mark. This can clearly distinguish between tested and untested parts, avoid confusion between parts, facilitate subsequent classification and management of parts, and eliminate the need for additional power sources for dot marking, thus improving the standardization and orderliness of the production process.

[0032] Example

[0033] Please see Figure 1-6 This utility model provides a technical solution: a clamping device for part inspection, including an operating table 1, a sealing gasket 9 fixed on the top of the operating table 1, a placement groove 8 provided on the inner side of the sealing gasket 9, and a first part 3 placed inside the placement groove 8; a clamping assembly 2 is provided on one side of the operating table 1, which is used to clamp and fix the first part 3 to be inspected; the operator places the first part 3 to be inspected in the placement groove 8 on the top of the operating table 1, the placement groove 8 plays a preliminary positioning role for the part, the sealing gasket 9 surrounds the outside of the placement groove 8 to ensure that an effective sealing area can be formed when the part is clamped, and a marking assembly 6 is provided on one side of the clamping assembly 2;

[0034] The marking component 6 includes a connecting rod 61, with a metal column 62 fixed to one side of the connecting rod 61 by bolts. The metal column 62 has a pointed tip at the bottom. When the support rod 26 moves downward with the clamping action, it will drive the entire marking component 6 to move downward synchronously. The pointed tip fixed to the bottom of the metal column 62 will also descend and press a tiny indentation or marking point on the surface of the first part 3 or the second part 4 to complete the inspection and marking. Items that fail the inspection will directly enter the scrap box, and no additional power source is needed for marking.

[0035] The clamping assembly 2 includes a cylinder 21 and two limiting frames 211. A rotating rod 29 is hinged to one side of the limiting frame 211. A support rod 26 is fixed to one end of the rotating rod 29. A pressure rod 27 is fixed to one side of the support rod 26. A sleeve 212 is provided on the outside of the pressure rod 27. A rubber layer 28 is fixed on the outside of the sleeve 212. The rubber layer 28 provides a flexible contact surface, which can effectively clamp the parts without scratching the surface of the parts. A push plate 24 is fixed to the push rod end of the cylinder 21. Slide rods 25 are fixed to both ends of the top of the push plate 24. Lubricating oil is applied to the slide rods 25 and the slide groove 210 regularly. The top of the slide rod 25 is inserted into the slide groove 210 of the rotating rod 29. Since the middle part of the rotating rod 29 is hinged to the limiting frame 211, the upward movement of the slide rod 25 will slide in the slide groove 210, forcing one end of the rotating rod 29 to rotate downward.

[0036] A groove 210 is provided on the side of the rotating rod 29 away from the rubber layer 28. The sliding rod 25 is slidably connected to the inner side of the groove 210. The connecting rod 61 is fixed to one side of one of the support rods 26. The limiting frame 211 is fixed to the top of the operating table 1. The pressure rod 27 is connected to the sleeve 212 by bolts. When the rotating rod 29 rotates downward, it drives the support rod 26 at its end and the pressure rod 27 at its lower end to move downward together.

[0037] Two guide rods 23 are fixed at the bottom of the operating table 1. A limit ring 22 is fixed at the bottom of the guide rod 23. One side of the push plate 24 is slidably connected to the outside of the guide rod 23 through a linear bearing. When the cylinder 21 is activated, its push rod extends and pushes the push plate 24 to move upward along the guide rod 23. The guide rod 23 and the limit ring 22 ensure the stability of the movement trajectory of the push plate 24 and prevent it from tilting.

[0038] The bottom of the operating table 1 is connected to the base 7 by bolts. The cylinder 21 is fixed to the bottom of the inner wall of the base 7. The top of the operating table 1 has an air hole 10, which is located inside the sealing gasket 9.

[0039] The first part 3 is welded to the top of the second part 4, which is mainly used to test the airtightness of the connection between the first part 3 and the second part 4. When the rubber layer 28 contacts the top of the first part 3, the first part 3 and the second part 4 are in the test state. A through hole is opened on one side of the base 7. The through hole is used for the air tube to pass through and communicate with the air hole 10. One end of the air hole 10 is connected to a positive pressure detector (not shown in the figure) through a hose. Its model is ATEQF620. The test air pressure of the first part 3 and the second part 4 is 3.5±0.1 bar. The leakage is not greater than 2ml / min. The test time is: inflation ≥20s, pressure holding ≥60s, test ≥20s. The test interval for the same part is not less than 1 minute.

[0040] Working principle: The first part 3 and the second part 4, which are welded together and are to be inspected, are placed in the placement groove 8 inside the sealing gasket 9 on the top of the operating table 1. At this time, the first part 3 is in the initial positioning state.

[0041] When it is necessary to clamp the first part 3, the cylinder 21 starts to work, and its push rod end pushes the push plate 24. One side of the push plate 24 is slidably connected to the outside of the guide rod 23 through a linear bearing. The bottom of the guide rod 23 is fixed with a limit ring 22 and fixed to the bottom of the operating table 1. Under the guidance of the guide rod 23, the push plate 24 moves linearly along the guide rod 23 to ensure the stability of the movement process.

[0042] As the slide bar 25 slides within the slide groove 210, it drives the rotating rod 29 to rotate around the hinge point with the limit frame 211. The support rod 26 fixed at one end of the rotating rod 29 moves accordingly, and the pressure rod 27 fixed on one side of the support rod 26 also moves synchronously. The outer side of the pressure rod 27 is connected to the sleeve 212 by bolts, and the outer side of the sleeve 212 is fixed with a rubber layer 28. Finally, the rubber layer 28 approaches and contacts the top of the first part 3, applying pressure to the first part 3 to achieve clamping and fixing. At this time, the first part 3 and the second part 4 are in the state of waiting to be tested. The pressure rod 27 is connected to the sleeve 212 by bolts, which facilitates replacement and maintenance.

[0043] After the clamping assembly 2 completes the clamping action, the support rod 26 synchronously drives the connecting rod 61 and the metal column 62 to move towards the top side of the first part 3, so that the tip of the bottom of the metal column 62 contacts the first part 3 and generates a dot mark on the outside of the first part 3, which can distinguish between tested and untested parts.

[0044] After the test is completed, the push rod of cylinder 21 retracts, causing the push plate 24 to move in the opposite direction along the guide rod 23, and the slide rod 25 slides in the opposite direction in the slide groove 210, causing the rotating rod 29 to rotate in the opposite direction, thereby causing the support rod 26, the pressure rod 27 and the rubber layer 28 to move away from the first part 3, loosening the clamping on the first part 3. At this time, the tested part can be removed.

[0045] In summary, the first part 3 and the second part 4 are placed in the placement groove 8 inside the sealing gasket 9 on the top of the operating table 1. As the slide rod 25 slides in the slide groove 210, it drives the rotating rod 29 to rotate around the hinge point with the limit frame 211, thereby causing the support rod 26 and the pressure rod 27 to move synchronously. Finally, the rubber layer 28 approaches and contacts the top of the first part 3, applying pressure to the first part 3 to achieve stable and reliable clamping and fixing, ensuring that the first part 3 and the second part 4 will not move in the test state, thus ensuring the accuracy of the test results.

[0046] The pressure rod 27 is connected to the sleeve 212 by bolts, making it easier and faster to replace the sleeve 212 and the rubber layer 28. When the rubber layer 28 is worn or damaged, the new sleeve 212 can be replaced simply by removing the bolts, which reduces maintenance costs and time and improves the overall service life of the equipment.

[0047] After the clamping assembly 2 completes the clamping action, the support rod 26 synchronously drives the connecting rod 61 and the metal column 62 to move towards the top of the first part 3, so that the tip of the bottom of the metal column 62 contacts the first part 3 and generates a dot mark, which can clearly distinguish between tested and untested parts, avoid parts confusion, facilitate subsequent classification and management of parts, and does not require additional power source for dot marking, thus improving the standardization and orderliness of the production process.
