Description

Technical Field

[0001] The utility model relates to the technical field of wear-resistant cast ball detection, in particular to a high-chromium cast ball detection device. Background Art

[0002] Wear-resistant steel balls, also known as wear-resistant media for grinders, are consumables. Their main purpose is to grind materials to make them finer to meet usage standards. They are mainly used in mines, power plants, cement plants, steel mills, silica sand plants, coal chemical industries and other fields. The annual consumption of steel balls in the world is 30-50 million tons, of which China consumes 3-5 million tons, making it a major steel ball consumer. After the production of wear-resistant steel balls is completed, they need to be tested to eliminate unqualified products. Usually, the hardness, diameter, surface and roundness of the steel balls need to be tested, and hardness testing is a destructive performance test, which is usually performed using a special hardness tester.

[0003] In the prior art, when testing the hardness of wear-resistant steel balls, the cast balls are usually fixed and then pressed down using a hardness tester. It is inconvenient to adjust the position of the wear-resistant cast balls and it is impossible to perform multi-position testing on them, which has great limitations. For this reason, we have developed a high chromium cast ball testing device. Utility Model Content

[0007] A testing platform, wherein a support seat is fixedly connected to the top of the testing platform, a placement seat is fixedly connected to the top of the support seat, a plurality of balls are installed on the inner wall of the placement seat, and the plurality of balls are arranged in a ring shape as a whole;

[0008] A support frame, the support frame is fixed on the top of the testing platform, the support frame is rotatably connected to a rotating shaft, a driving wheel is installed on the rotating shaft, the driving wheel is located directly below the placement seat, and one end of the rotating shaft passing through the support frame is fixedly connected to a locking wheel;

[0010] Based on the above technical solution, its use principle and the technical effects produced are as follows:

After moving to the appropriate position, the deflection rod is released, so that the elastic force of the elastic member drives the limit block to be stuck in the tooth gap of the locking wheel, so that the driving wheel can be locked to prevent it from rotating during the test process, and when the next adjustment is needed, the deflection rod can be pulled again.

[0020] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0021] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0022] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.);

[0023] An active connection is a connection in which parts or components are fixed so that they can move relative to each other.

Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. It should be noted that the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.

[0034] According to the concept of this application, Figures 1 to 4 To describe an embodiment of a high-chromium cast ball detection device for hardness testing of large high-chromium wear-resistant cast balls. Specifically, the high-chromium cast ball detection device is constructed as an integrated structure, which has three components such as a detection table 1, a support frame 5 and a connecting plate 9. Through the mutual cooperation of the set placement seat 3, the ball 4, the driving wheel 7 and other structures, the wear-resistant cast ball can be driven to rotate on the placement seat 3, which is convenient for detecting different positions of the cast ball through the set hardness tester 15, thereby improving the accuracy of the detection, and through the mutual cooperation of the set deflection rod 10, the locking wheel 8, the limit block 11, the elastic member 12 and other structures, the driving wheel 7 can be locked or unlocked to prevent it from rotating during the detection process.

[0035] Combination Figure 1-4 As shown, the utility model provides a high chromium cast ball detection device, comprising:

[0036] A testing table 1, the top of the testing table 1 is fixedly connected to a support seat 2, the top of the support seat 2 is fixedly connected to a placement seat 3, a plurality of balls 4 are installed on the inner wall of the placement seat 3, and the plurality of balls 4 are arranged in a ring shape as a whole;

[0037] A support frame 5 is fixed on the top of the testing platform 1. A rotating shaft 6 is rotatably connected to the support frame 5. A driving wheel 7 is installed on the rotating shaft 6. The driving wheel 7 is located directly below the placement seat 3. One end of the rotating shaft 6 that passes through the support frame 5 is fixedly connected to a locking wheel 8.

[0038] The connecting plate 9 is fixed on the supporting seat 2 , and a deflection rod 10 is rotatably connected to the side wall of the connecting plate 9 , one end of the deflection rod 10 is fixedly connected to a limiting block 11 , and an elastic member 12 is fixedly connected to the side wall of the deflection rod 10 .

[0039] The testing platform 1 is mainly used to provide support. According to the technical solution of the present application, a support arm 13 is also fixedly connected to the top of the testing platform 1. An electric telescopic rod 14 is installed on the support arm 13. A hardness tester 15 is installed at the bottom end of the electric telescopic rod 14. Both the electric telescopic rod 14 and the hardness tester 15 are powered by an external power supply. By starting the electric telescopic rod 14 to drive the hardness tester 15 to move downward, the surface hardness of the cast ball can be tested.

[0040] The placement seat 3 is mainly used to place and position the wear-resistant cast ball. In some embodiments, the cross-sectional shape of the placement seat 3 can be set to a ring shape, a square shape or a polygonal shape. According to the technical solution of the present application, the placement seat 3 is set to a ring shape as a whole, and the inner wall of the placement seat 3 is adapted to the spherical arc surface, so that the wear-resistant cast ball fits with the placement seat 3 and is easy to position.

One of the rotating shafts 6 passes through the support frame 5, and the end through which it passes is also fixedly connected to a handle 16. Turning the handle 16 drives one of the rotating shafts 6 to rotate, and then the two rotating shafts 6 rotate simultaneously in the same direction through the provided belts and pulleys.

[0042] According to the technical solution of the present application, there are four driving wheels 7, which are arranged in a rectangular shape as a whole, and are made of rubber material. When the two rotating shafts 6 rotate at the same time, the driving wheels 7 are driven to rotate accordingly, thereby driving the wear-resistant cast ball to rotate on the placement seat 3, which is convenient for detecting different positions of the cast ball through the set hardness tester 15, thereby improving the accuracy of the detection.

[0045] Specifically, when it is necessary to test the wear-resistant cast ball, first place the wear-resistant cast ball on the placement seat 3 so that it contacts the ball 4, then start the electric telescopic rod 14 to drive the hardness tester 15 to move downward, so that the surface hardness of the cast ball can be tested, and then turn the handle 16 to drive one of the rotating shafts 6 to rotate, and then use the belt and pulley to make the two rotating shafts 6 rotate in the same direction at the same time, so as to drive the four driving wheels 7 to rotate at the same time, and use the friction between the driving wheel 7 and the wear-resistant cast ball to drive the wear-resistant cast ball to rotate on the placement seat 3, so as to facilitate the detection of different positions of the cast ball through the set hardness tester 15, thereby improving the accuracy of the detection. After moving to the appropriate position, release the deflection rod 10, so that the elastic force of the elastic member 12 drives the limit block 11 to be stuck in the tooth gap of the locking wheel 8, so as to lock the driving wheel 7 to prevent it from rotating during the detection process. When the next adjustment is needed, pull the deflection rod 10 again.
