Description

Technical Field

[0001] This utility model relates to the technical field of hardness testing auxiliary equipment, and more specifically, to a quick clamping and positioning fixture for steel ball hardness testing samples. Background Technology

[0002] In the production process of steel balls, hardness testing is a crucial quality control step, as the test results directly affect the performance and lifespan of the steel balls. During hardness testing, the steel balls need to be positioned to ensure they do not shift during the testing process and to guarantee the accuracy of subsequent test results. However, existing technologies have the following shortcomings:

[0003] After the steel balls are tested, regardless of whether the hardness test is qualified, the operators usually manually remove the tested steel balls from the fixture and then classify the qualified and unqualified steel balls. After such a long operation, the workload of the operators will be large and the actual work efficiency will be reduced.

[0004] Therefore, there is an urgent need for a quick clamping and positioning fixture for steel ball hardness testing samples to solve the above problems. Utility Model Content

[0027] Example:

[0028] like Figure 1-5As shown, this embodiment proposes a rapid clamping and positioning fixture for steel ball hardness testing samples, including a base 1, a U-shaped frame 2 fixedly connected to the top of the base 1, a connecting shaft 3 horizontally fixedly connected to the U-shaped frame 2, a bearing plate 4 rotatably mounted on the connecting shaft 3, a cylindrical block 5 fixedly connected to the center of the top of the bearing plate 4, and a notch 6 formed on the upper surface of the cylindrical block 5. The steel ball to be tested is placed on the cylindrical block 5, with part of the steel ball located within the notch 6 for initial positioning. A bracket 7 is fixedly connected to the back of the U-shaped frame 2. A first electric push rod 8 is fixedly installed on the lower surface of the upper part of the bracket 7. A mounting plate 9 is fixedly connected to the push rod end of the first electric push rod 8. A positioning ring 10 is fixedly connected to the front end of the mounting plate 9. The positioning ring 10 is located above the cylindrical block 5. The inner diameter of the positioning ring 10 is smaller than the diameter of the cylindrical block 5. When the first electric push rod 8 is activated, the mounting plate 9 and the positioning ring 10 are moved downwards, so that the positioning ring 10 abuts against the outer surface of the steel ball, thereby positioning the steel ball. A first fixing plate 11 and a second fixing plate are fixedly connected to the top of the base 1. 12. Two guide rods 13 are fixedly connected between the first fixing plate 11 and the second fixing plate 12. After the steel ball completes the hardness test, the first electric push rod 8 drives the mounting plate 9 and the positioning ring 10 to move upward, releasing the fixation of the steel ball. A second electric push rod 14 is fixedly connected to the right side surface of the first fixing plate 11. A vertical plate 15 is fixedly connected to the push rod end of the second electric push rod 14. A columnar part 16 is fixedly connected to the back of the vertical plate 15 near the upper end. If the hardness test of the steel ball is qualified, the second electric push rod 14 is activated, and the second guide rod 13 drives the steel ball to move upward. The electric push rod 14 drives the vertical plate 15 to move to the right, and the column 16 follows the vertical plate 15 to move horizontally to the right. The bottom of the bearing plate 4 is fixedly connected to the connecting plate 17, which has a through-hole 18. The column 16 is located in the through-hole 18, which is lower on the left and higher on the right. As the column 16 moves in the through-hole 18, it can drive the bearing plate 4 to rotate clockwise through the cooperation of the column 16 and the connecting plate 17. The bearing plate 4 itself is higher on the left and lower on the right, so that the steel ball can be separated from the column block 5.

[0029] like Figure 1 and Figure 2 As shown, the front and rear ends of the bearing plate 4 are respectively fixedly connected to a first baffle 19 and a second baffle 20. The first baffle 19 and the second baffle 20 are at the same height. The upper surface of the first baffle 19 is located above the cylindrical block 5. The first baffle 19 and the second baffle 20 cooperate to prevent the steel ball from falling from the front and rear of the bearing plate 4 and play a guiding role.

[0030] like Figure 1As shown, two symmetrically distributed limiting frames 21 are fixedly connected to the top of the base 1. A collection box 22 is set inside the limiting frame 21. The two collection boxes 22 are located directly below the left and right end faces of the support plate 4, respectively. The two limiting frames 21 can limit the two collection boxes 22 to prevent the collection boxes 22 from shifting. When the support plate 4 rotates, the steel balls can be collected through the collection boxes 22.

[0031] like Figure 1 and Figure 2 As shown, the two guide rods 13 are symmetrically distributed about the central axis of the first fixed plate 11. The vertical plate 15 is slidably sleeved on the two guide rods 13. The two guide rods 13 can provide auxiliary guidance for the vertical plate 15 and ensure the stability of the vertical plate 15 during movement.

[0032] like Figure 1 and Figure 2 As shown, the front and rear ends of the bearing plate 4 are in contact with the U-shaped frame 2, which can prevent the bearing plate 4 from shifting back and forth.

[0033] The working principle of the above embodiment is as follows: The first electric push rod 8 and the second electric push rod 14 are electrically connected. The steel ball to be tested is placed on the cylindrical block 5, so that part of the steel ball is located in the notch 6, and the steel ball is initially positioned. Then, the first electric push rod 8 is activated, which drives the mounting plate 9 and the positioning ring 10 to move downward, so that the positioning ring 10 abuts against the outer surface of the steel ball, thereby positioning the steel ball. The operator can use a handheld hardness tester to test the hardness of the steel ball. After the hardness test is completed, the first electric push rod 8 drives the mounting plate 9 and the positioning ring 10 to move upward, releasing the fixation of the steel ball. If the hardness test of the steel ball is qualified, the second electric push rod 14 is activated, which drives the vertical plate 15 to move to the right. The cylindrical component 16 follows the vertical plate 15 and moves horizontally to the right. While the cylindrical component 16 moves in the inclined opening 18, it cooperates with the connecting plate 17 to drive the bearing... When the carrier plate 4 rotates clockwise, its left side is higher than its right side, allowing the steel ball to detach from the cylindrical block 5. The first baffle 19 and the second baffle 20 work together to prevent the steel ball from falling from the front or back of the carrier plate 4. Qualified steel balls slide down the inclined carrier plate 4 into the collection box 22 on the right. Conversely, if the steel ball fails the hardness test, the second electric push rod 14 moves the vertical plate 15 to the left, causing the cylindrical component 16 to move horizontally to the left. As the cylindrical component 16 moves within the inclined opening 18, it works in conjunction with the connecting plate 17 to rotate the carrier plate 4 counterclockwise, making it lower on the left and higher on the right. The steel ball detaches from the cylindrical block 5, and the unqualified steel ball slides into the collection box 22 on the left. This automatic sorting of qualified and unqualified steel balls eliminates the need for manual sorting and effectively reduces the workload of workers.

[0034] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
