Abstract
Description
Technical Field
[0001] The utility model relates to the field of machinery, in particular to pendulum impact tests, and more particularly to a waste sample collection device for a pendulum impact testing machine. Background Art
[0002] A pendulum impact testing machine is a device used to measure the impact toughness value of metal and non-metal materials and detect the impact resistance ability of materials. After the material is made into a specimen with a notch in the middle according to the standard, it is placed in the impact testing machine, and the impact resistance energy value of the material is measured through the impact of the pendulum. In the prior art, after the specimen is impacted, it is sent to a waste sample collection box through a transmission belt. All specimens are placed in a waste collection box, which is not convenient for later manual re-inspection or traceability. With the increase in the types of materials, the requirements for material analysis also increase. After the impact test, the specimens need to be re-inspected and analyzed. When all specimens are placed in a waste collection box, it is difficult to complete this work. If the specimens are re-inspected immediately after a test, the test efficiency will be greatly reduced. Summary of the Invention

A receiving funnel is arranged on the base, and the receiving funnel is located above the waste box. A detection switch is arranged on the inner wall of the receiving funnel. The control end of the motor and the signal output end of the detection switch are both connected to a controller.
[0005] Further, any one of the waste boxes is connected to the annular guide rail through two guide posts. Two guide holes matching with the guide posts are arranged at the bottom of any one of the waste boxes. The guide posts are fixedly arranged on the slider.

[0014] The present utility model will be further described below in conjunction with embodiments, but the present utility model is not limited to these embodiments. Any similar structure and its similar changes of the present utility model shall be included in the protection scope of the present utility model. The use of directions such as up, down, front, back, left, and right in the present utility model is only for convenient and clear description and does not limit the technical solution of the present utility model.
[0015] As Figures 1 - 5 shown, a waste sample collection device for a pendulum impact testing machine according to the present utility model includes a base 1. A ring-shaped conveying device is arranged on the base 1. The ring-shaped conveying device includes a ring-shaped guide rail 2, a ring-shaped chain 3, a driving sprocket 4, a driven sprocket 5, a motor 6 and a speed reducer 7 arranged on the base 1. The ring-shaped chain 3 is located inside the ring-shaped guide rail 2. The driving sprocket 4 and the driven sprocket 5 are connected to the inside of the ring-shaped chain 3. The output shaft of the motor 6 is connected to the driving sprocket 4 through the speed reducer 7. A plurality of sliders are arranged at intervals along the circumference on the ring-shaped guide rail 2. A waste material box 8 is detachably connected to any one of the sliders respectively. The ring-shaped chain 3 is connected to each slider through a connecting piece. A receiving funnel 9 is arranged on the base 1. The receiving funnel 9 is located above the waste material box 8. A detection switch 10 is arranged on the inner wall of the receiving funnel 9. The control end of the motor 6 and the signal output end of the detection switch 10 are both connected to a controller (not shown in the figure).
[0016] Further, each waste box 8 is respectively connected to the annular guide rail 2 through two guide posts 11. Two guide holes cooperating with the guide posts 11 are provided at the bottom of each waste box 8. The guide posts 11 are fixedly arranged on the slider. The guide posts 11 pass downward through the slider and form a sliding pair along the circumferential direction of the annular guide rail 2 with the annular guide rail 2.
[0017] Further, the detection switch 10 is a photoelectric induction switch.
[0018] Further, the number of the waste boxes 8 is 48.
[0019] Specifically, the annular conveying device, the annular guide rail 2, the annular chain 3, the driving sprocket 4, the driven sprocket 5, the motor 6, the speed reducer 7, the detection switch 10, the photoelectric induction switch, etc. in this embodiment all adopt well-known solutions in the prior art, which are already understood by those skilled in the art and will not be elaborated here.
[0020] The working principle of this embodiment:
[0021] In this embodiment, there are a total of 48 waste boxes 8, and each waste box 8 holds 3 specimens, with a total of 144 (corresponding to the test quantity of the existing full-automatic impact testing machine with a low-temperature box). Each waste box 8 has its own corresponding position or number, which is convenient for later re-inspection and traceability.
[0022] Waste collection process: In the previous process, after the specimen is impacted, it is conveyed through the transmission belt and falls into the receiving funnel 9. The photoelectric induction switch counts, sends the signal to the controller, and the specimen falls into the waste box 8. When the counting quantity reaches 3, the controller starts the motor 6 of the annular conveying device, and conveys the next waste box 8 to the lower part of the receiving funnel 9 at a specified interval to continue the test. The utility model collects the specimens in multiple boxes through the annular conveying device and counts through the photoelectric induction switch, which greatly facilitates the later manual re-inspection and traceability and does not affect the normal test efficiency.
[0023] There are two positioning holes at the bottom of the waste box 8. The waste box 8 is placed and fixed on the annular conveying device through the guide posts 11, which is convenient for manual picking and placing, and also ensures that there will be no displacement during the conveying process.
