[0001] The utility model relates to the technical field of tooling inspection tools, in particular to a reduction gear box casting inspection tool. Background Art

[0002] The reducer housing casting gauge is a tool used to inspect and measure the reducer housing castings. Since the reducer housing plays an important role in transmission and support in the industrial field, its quality and precision are crucial to the performance of the entire mechanical system. The main purpose of the casting gauge is to ensure that the size, shape and quality of the reducer housing castings meet the design requirements.

[0003] However, in the prior art, the size of the reducer housing is generally measured using tools such as a tape measure. When the reducer housing has an irregular outer surface, measurement is difficult, and accurate data cannot be obtained only by visual observation and tape measure measurement, which is defective. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problem that in the prior art, the size of the reducer case is generally measured by tools such as a tape measure, and when the reducer case has an irregular outer surface, measurement is difficult, and accurate data cannot be obtained only by naked eye observation and tape measure measurement, and a reducer case casting inspection fixture is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a reduction gear case casting inspection fixture, comprising a bottom support plate, the upper surface of the bottom support plate near the two ends is fixedly connected to a support column, the relative surfaces of the two support columns are rotatably connected to a screw rod through a rotating shaft, one side surface of one of the support columns is fixedly connected to a motor, the output end of the motor is fixedly connected to one end of the screw rod, the outer surface of the screw rod is threadedly connected to a moving block, the lower surface of the moving block is fixedly connected to a push plate, the relative surfaces of the two support columns are fixedly connected to the two ends of a limiting slide rail, and a back plate is provided on one side surface of the other support column, and a limiting ring is fixedly connected to one side surface of the back plate, and a ruler is slidably embedded in the inner part of the limiting ring.

[0006] Furthermore, two support blocks are fixedly connected to the upper surface of the bottom support plate, and adjustment grooves are provided on the upper surfaces of the two support blocks. Two universal wheels are embedded inside the two adjustment grooves, and a pad is fixedly connected to one side surface of the four universal wheels.

[0007] Furthermore, the upper surfaces of the pad close to both sides are fixedly connected with baffles, and the two baffles are arranged opposite to each other.

[0008] Furthermore, a spring is fixedly connected to one side surface of the back plate, one end of which is fixedly connected to the outer surface of another support column, and a telescopic rod is fixedly connected to one side surface of the back plate, the other end of which is fixedly connected to the outer surface of the support column.

[0009] Furthermore, the inner wall surface of the spring is sleeved on the outer surface of the telescopic rod.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] 1. In the utility model, when in use, the workpiece to be inspected is placed on the upper surface of the bottom support plate close to the back plate, the angle of the workpiece is adjusted, and then the motor drives the lead screw to rotate. Under the action of the thread and the limit slide rail, the moving block drives the push plate to move, pushing the workpiece to slide on the upper surface of the bottom support plate until one side surface of the workpiece fits with the back plate, the motor stops working, the ruler moves synchronously with the push plate, and slides inside the limit ring. After the motor stops working, the limit ring and the ruler are used to read the size of the workpiece. The operation is simple and can be applied to reducer cases of different specifications.

[0012] 2. In the utility model, the workpiece is placed on the upper surface of the pad. When the push plate pushes the workpiece, the workpiece transmits kinetic energy to the pad, so that the pad slides under the action of four universal wheels. The adjustment groove on the upper surface of the support block controls the moving range of the pad. After the workpiece is placed on the upper surface of the pad, there is no need to manually fine-tune the angle of the workpiece, which saves manpower and improves the detection efficiency of the workpiece. When the back plate is squeezed by the workpiece, the spring compresses the stroke to absorb kinetic energy and increase the service life of parts. The telescopic rod limits the moving trajectory of the back plate to avoid tilting of the back plate and ensure the accuracy of the measurement data. The spring is sleeved on the outer surface of the telescopic rod to avoid bending and deformation after being acted upon by external force, thereby ensuring the normal operation of parts.

[0021] In this embodiment, when in use, the workpiece to be inspected is placed on the upper surface of the bottom support plate 1 close to the back plate 9, the angle of the workpiece is adjusted, and then the motor 7 drives the screw 3 to rotate. Under the action of the thread and the limiting slide rail 6, the moving block 4 drives the push plate 5 to move, pushing the workpiece to slide on the upper surface of the bottom support plate 1 until one side surface of the workpiece fits with the back plate 9. The motor 7 stops working, and the ruler 12 moves synchronously with the push plate 5 and slides inside the limiting ring 11.

Under the action of the thread and the limit slide rail 6, the moving block 4 drives the push plate 5 to move, and the workpiece is placed on the upper surface of the pad 15. When the push plate 5 pushes the workpiece, the workpiece transmits kinetic energy to the pad 15, so that the pad 15 slides under the action of four universal wheels 17. The adjustment groove 14 opened on the upper surface of the support block 13 controls the movement range of the pad 15 until one side surface of the workpiece fits with the back plate 9. The motor 7 stops working, and the ruler 12 moves synchronously with the push plate 5 and slides inside the limit ring 11. After the motor 7 stops working, the limit ring 11 and the ruler 12 are used to read. When the back plate 9 is squeezed by the workpiece, the spring 8 compresses the stroke to absorb kinetic energy, and the telescopic rod 10 limits the movement trajectory of the back plate 9. The spring 8 is sleeved on the outer surface of the telescopic rod 10 to prevent the spring 8 from bending.
