Description

Technical Field

[0001] This utility model relates to the field of casting inspection technology, specifically a casting inspection device. Background Technology

[0002] Precision casting refers to the general term for processes that produce castings with precise dimensions. Compared to traditional sand casting, precision casting produces castings with more accurate dimensions and better surface finish. It includes investment casting, ceramic mold casting, metal mold casting, pressure casting, and lost foam casting. Precision casting, also known as lost-wax casting, produces precise, complex products that closely resemble the final shape of the part. These parts can be used directly with little or no machining and are a near-net-shape forming advanced process. Castings produced through precision casting are also called precision castings.

[0003] Patent CN222288007U discloses a device for detecting the airtightness of aluminum alloy die castings, relating to the field of airtightness testing technology. The device includes a cylinder with a placement cavity and a lifting cavity inside. A first screw is rotatably mounted on the bottom inner wall of the placement cavity, near both sides. Limiting blocks are threaded onto the surface of the first screw, and a lifting plate is fixed between the limiting blocks. In this invention, when the airtightness of the casting fails the test, a second motor drives the second screw to rotate via a third and fourth gear. The rotation of the second screw, through the limiting components, causes the convex plate to descend. An electric push rod then pushes an arc plate, which in turn pushes the casting at the top of the convex plate out of the discharge hole. Once the casting passes the test, it can be removed from the convex plate, thus facilitating the classification of qualified and unqualified castings and improving testing efficiency.

[0004] However, the above-disclosed casting inspection devices generally have low inspection efficiency and limited freedom, and cannot perform multi-angle, repeated inspections of castings, lacking a high degree of freedom inspection structure. Utility Model Content

[0005] The purpose of this utility model is to provide a casting inspection device to solve the problems of the general detection efficiency and degree of freedom of existing casting inspection devices, the inability to perform multi-angle and repeated inspections of castings, and the lack of a high degree of freedom detection structure.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a casting inspection device, comprising an annular operating table, a rotating cavity being formed at the top of the operating table, and an annular toothed plate being rotatably mounted inside the rotating cavity; a lifting cylinder being installed in the middle of the operating table, and a lifting platform being provided at the output end of the lifting cylinder; a detection device being provided at the top of the annular toothed plate, the detection device comprising an adjusting cylinder and a mounting bracket installed at the output end of the adjusting cylinder, an inner rotating tube being rotatably mounted in the middle of the mounting bracket, an outer rotating tube being movably mounted on the outer wall of the inner rotating tube, symmetrical swing columns being fixedly arranged on both sides of the inner rotating tube, swing frames being movably mounted at both ends of the swing columns, a support being fixedly arranged at the top of the swing frame, and a sensor being installed at the end of the support.

The output end of the first motor is equipped with a first drive gear that meshes with the first deflection gear, and the output end of the second motor is equipped with a second drive gear that meshes with the second deflection gear.

[0009] As a further improvement of this utility model: a T-shaped groove is provided at the bottom of the mounting bracket, and a T-shaped rail that matches it is fixedly provided at the top of the inner rotating tube; a convex ring is provided on the outer wall of the inner rotating tube, and a groove that matches it is provided on the inner wall of the outer rotating tube.

[0010] As a further improvement of this utility model: a control panel is provided on the outer wall of the operating table, an annular limiting rail is provided at the bottom of the annular toothed plate, and a limiting groove that cooperates with it is provided at the top of the rotating cavity.

[0011] As a further improvement of this utility model: a rotary motor is installed at the bottom of the operating table, and a rotary gear that meshes with the annular toothed plate is installed at the output end of the rotary motor.

[0024] The following will be combined with the appendix Figures 1 to 7 The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This utility model provides an improved casting inspection device, such as... Figures 1-7 As shown, the device includes an annular operating platform 1, with a rotating cavity 101 at the top of the operating platform 1. An annular toothed plate 102 is rotatably installed inside the rotating cavity 101. A lifting cylinder 2 is installed in the middle of the operating platform 1, and a lifting platform 201 is provided at the output end of the lifting cylinder 2. A detection device 3 is provided on the top of the annular toothed plate 102. The detection device 3 includes an adjusting cylinder 302 and a mounting bracket 301 installed at the output end of the adjusting cylinder 302. An inner rotating tube 303 is rotatably installed in the middle of the mounting bracket 301. An outer rotating tube 306 is movably installed on the outer wall of the inner rotating tube 303. Symmetrical swing columns 317 are fixedly installed on both sides of the inner rotating tube 303. Swing frames 318 are movably installed at both ends of the swing columns 317. A bracket 320 is fixedly installed on the top of the swing frame 318. A sensor 321 is installed at the end of the bracket 320.

[0026] This invention allows the testing device 3 to rotate freely via the annular toothed plate 102, and the height of the casting to be tested can be freely adjusted via the lifting platform 201.

[0027] See appendix Figure 4 -Appendix Figure 7 A deflection gear 309 is installed on the outer wall of the inner rotating tube 303, and a linkage 310 is installed on the outer wall of the outer rotating tube 306.
