Description

Technical Field

[0001] This invention relates to the field of impact testing technology, and in particular to a device for testing the impact performance of ship components. Background Technology

[0002] For impact performance testing of ship steel plates, the core equipment is the pendulum impact testing machine. This equipment is used to test the toughness of steel plates. The placement of the specimen during the testing process is crucial. The core requirements are: the notch of the specimen should face away from the pendulum cutting edge, the specimen should be in close contact with the support of the testing equipment, and the symmetrical plane of the notch on the specimen should be aligned with the center plane of the two supports. Therefore, in order to ensure the accuracy of the specimen placement, the staff will use a "centering template" to assist in observation and positioning. For small specimens, shims are also needed to adjust the positional relationship between the specimen and the support. This results in low specimen placement efficiency, and the placement operation relies on auxiliary tools. The error of human observation of the specimen position will affect the accuracy of the measurement data of the testing equipment.

[0003] Therefore, the present invention provides a device for testing the impact performance of ship components to meet the requirements. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a testing device for the impact performance of ship components. By setting a positioning mechanism, the side baffle can position the end of the steel plate sample so that when the end of the steel plate sample abuts against the side baffle, the notch on the steel plate sample is exactly located at the center of the two supports. This eliminates the need for operators to use a "centering template" to observe and determine the position of the notch. This setting not only improves the efficiency of steel plate sample placement but also ensures the accuracy of the steel plate sample placement position, thereby improving the accuracy of the equipment's testing. The above setting can solve the problem of low sample placement efficiency and reliance on auxiliary tools in the current testing equipment, which affects the accuracy of the measurement data.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An impact performance testing device for ship components includes a base and a steel plate sample. Two supports are fixedly connected to one side of the top of the base, and a bracket is fixedly connected to the other side of the top of the base. A control mechanism is fixedly connected to the bracket, and a drive mechanism is mounted on the top of the bracket. A pendulum is fixedly connected to one end of the drive mechanism, and a pendulum hammer is fixedly connected to the bottom of the pendulum. A scale is fixedly connected to one end of the drive mechanism near the pendulum, and a locking mechanism and a positioning mechanism are fixedly connected to the top of the scale. The positioning mechanism is used to fix the relative position between the supports and the steel plate sample, and the positioning mechanism is connected to the supports.

[0006] Optionally, the positioning mechanism includes two positioning plates fixedly connected to the top of the two supports, with a first positioning frame and a second positioning frame slidably connected to the top of the two positioning plates respectively, and the steel plate sample placed on the top of the two positioning plates.

[0007] Optionally, the top of the positioning plate is provided with a sliding groove, and the bottom of the first positioning frame and the second positioning frame are both fixedly connected with a sliding plate, which is limited to sliding within the sliding groove.

[0008] Optionally, a pull plate is fixedly connected to the side of the first positioning frame and the second positioning frame away from each other, and the pull plate is perpendicular to the first positioning frame and the second positioning frame.

[0009] Optionally, both the first positioning frame and the second positioning frame have a rectangular outline, and an arc-shaped plate is fixedly connected to the side of the first positioning frame away from the second positioning frame. The arc-shaped plate has a circular arc outline.

[0010] Optionally, a side baffle is fixedly connected to the side of the second positioning frame away from the first positioning frame, and the side baffle extends from one side of the second positioning frame and fits against the end of the steel plate sample.

[0011] Optionally, a front baffle and a rear baffle are fixedly connected to both ends of the positioning plate, the front baffle is close to the steel plate sample, and the outer wall of the steel plate sample is in contact with the inner wall of the front baffle.

[0012] Optionally, a limiting cylinder is fixedly connected to the inner wall of the rear baffle, and a spring is fixedly connected inside the limiting cylinder. The first positioning frame and the second positioning frame are both connected to the limiting cylinder through the spring.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a positioning mechanism, firstly, when the staff places the steel plate sample on top of the support, the side baffle can position the end of the steel plate sample so that when the end of the steel plate sample abuts against the side baffle, the notch on the steel plate sample is exactly located at the center of the two supports. The staff does not need to use a "centering template" to help observe and judge the position of the notch. This setting can not only improve the efficiency of placing the steel plate sample, but also ensure the accuracy of the steel plate sample placement position, thereby improving the accuracy of the equipment detection. Secondly, after the steel plate sample is placed, a clamping force can be applied to the steel plate sample under the action of the spring. Under the action of the clamping force, the steel plate sample is clamped and fixed between the front baffle and the second positioning frame and the first positioning frame. This setting can improve the stability after the steel plate sample is placed, thereby avoiding the positional deviation of the steel plate sample due to equipment shaking or collision by the staff, and further improving the accuracy of the measurement data of the testing equipment. Finally, both the first and second positioning frames slide within the grooves on the top of the positioning plate via sliding plates, and both the first and second positioning frames are powered by springs. Therefore, under the elastic force of the springs, the first and second positioning frames can adaptively adjust according to the thickness of the steel plate sample, thereby clamping and fixing steel plate samples of different sizes. Compared with existing technologies, this setting eliminates the need for operators to adjust the position of the steel plate sample using shims, improving the ease of use of the equipment.

[0023] like Figures 1 to 3 As shown, an embodiment of the present invention provides a test device for the impact performance of ship components, including a base 1 and a steel plate sample 22. Two supports 2 are fixedly connected to one side of the top of the base 1, and a bracket 3 is fixedly connected to the other side of the top of the base 1. A control mechanism 4 is fixedly connected to the bracket 3, and a drive mechanism 5 is installed on the top of the bracket 3. A pendulum 6 is fixedly connected to one end of the drive mechanism 5, and a pendulum 7 is fixedly connected to the bottom of the pendulum 6. A scale 8 is fixedly connected to one end of the drive mechanism 5 near the pendulum 6, and a locking mechanism 9 is fixedly connected to the top of the scale 8.

[0024] In the above structure, the pendulum 7 passes through the middle of the two supports 2 during its swing. Therefore, the steel plate sample 22 is placed on top of the two supports 2. When the pendulum 7 swings towards the supports 2, it can impact the steel plate sample 22. At this time, the value generated by the pendulum 7 impacting the steel plate sample 22 will be displayed on the scale 8 for easy observation and recording by the staff. In this technical solution, the drive mechanism 5 is used to drive the pendulum 6 to swing, the locking mechanism 9 is used to lock and fix the pendulum 6, and the control mechanism 4 is used to allow the staff to operate the drive mechanism 5 and the locking mechanism 9. The working principle of the drive mechanism 5 and the locking mechanism 9 in cooperation with the pendulum 6 is disclosed as prior art and will not be described in detail here.

[0025] As one implementation method in this embodiment, such as Figures 1 to 7As shown, the positioning mechanism is used to fix the relative position between the support 2 and the steel plate sample 22. The positioning mechanism is connected to the support 2 and includes two positioning plates 10 fixedly connected to the top of the two supports 2. The top of the two positioning plates 10 is slidably connected to the first positioning frame 15 and the second positioning frame 19, respectively. The steel plate sample 22 is placed on the top of the two positioning plates 10. The two ends of the positioning plates 10 are fixedly connected to the front baffle 11 and the rear baffle 12, respectively. The front baffle 11 is close to the steel plate sample 22, and the outer side wall of the steel plate sample 22 is in contact with the inner wall of the front baffle 11. The inner wall of the rear baffle 12 is fixedly connected to the limiting cylinder 13, and the limiting cylinder 13 is fixedly connected to the spring 14. The first positioning frame 15 and the second positioning frame 19 are both connected to the limiting cylinder 13 through the spring 14. The top of the positioning plate 10 is provided with a sliding groove 21. The bottom of the first positioning frame 15 and the second positioning frame 19 are both fixedly connected to the sliding plate 18, which slides within the sliding groove 21.

[0026] In the above structure, the two positioning plates 10 are respectively installed on the top of the two supports 2 by screws. The front baffle 11 and the rear baffle 12 are fixed at both ends of the positioning plates 10 respectively. The thickness of the front baffle 11 is greater than that of the rear baffle 12. The front baffle 11 is used to position the steel plate sample 22. During the placement of the steel plate sample 22, the operator places the notched side of the steel plate sample 22 against the inner wall of the front baffle 11. After the steel plate sample 22 is placed, the inner wall of the front baffle 11 can assist in positioning one side of the outer wall of the steel plate sample 22.

[0027] Furthermore, a first positioning frame 15 and a second positioning frame 19 are slidably mounted on the top of the two positioning plates 10, respectively. The first positioning frame 15 is installed on the positioning plate 10 near the outside of the testing equipment. When the operator places the steel plate sample 22, it first contacts the first positioning frame 15. Since the first positioning frame 15 and the second positioning frame 19 are connected to the rear baffle 12 by springs 14, the first positioning frame 15 and the second positioning frame 19 always have the power to move towards the front baffle 11 under the elastic force of the springs 14. With this arrangement, after the steel plate sample 22 passes through the first positioning frame 15 and the second positioning frame 19 in sequence, a clamping force can be applied to the steel plate sample 22 under the elastic force of the springs 14. Under the action of the clamping force, the steel plate sample 22 is clamped and fixed between the front baffle 11 and the second positioning frame 19 and the first positioning frame 15. This arrangement can improve the stability of the steel plate sample 22 after it is placed, thereby avoiding the positional deviation of the steel plate sample 22 due to equipment shaking or collisions by the operator, and improving the accuracy of the measurement data of the testing equipment.

[0028] Furthermore, according to the requirements of the standard sample, the length and height of the steel plate sample 22 are fixed. However, the thickness of the small-sized steel plate sample 22 is less than that of the standard steel plate sample 22. Therefore, in order to make this equipment applicable to steel plate samples 22 of different sizes, the first positioning frame 15 and the second positioning frame 19 can both slide on the top of the positioning plate 10. The distance between the first positioning frame 15 and the second positioning frame 19 and the front baffle 11 is also adjusted during the sliding process, so as to be applicable to steel plate samples 22 of different thicknesses. Specifically, the first positioning frame 15 and the second positioning frame 19 are both limited to sliding in the slide groove 21 on the top of the positioning plate 10 by the sliding plate 18, and the first positioning frame 15 and the second positioning frame 19 are both subjected to sliding power by the spring 14. Therefore, under the elastic force of the spring 14, the first positioning frame 15 and the second positioning frame 19 can make adaptive adjustments according to the thickness of the steel plate sample 22, thereby clamping and fixing steel plate samples 22 of different sizes. Compared with the existing technology, this setting eliminates the need for the operator to adjust the position of the steel plate sample 22 with shims, and improves the convenience of using the equipment.

[0029] In this embodiment, as Figures 1 to 7 As shown, a pull plate 17 is fixedly connected to the side of the first positioning frame 15 and the second positioning frame 19 away from each other. The pull plate 17 is perpendicular to the first positioning frame 15 and the second positioning frame 19. The first positioning frame 15 and the second positioning frame 19 are both rectangular in shape. An arc plate 16 is fixedly connected to the side of the first positioning frame 15 away from the second positioning frame 19. The arc plate 16 has a circular arc shape. A side baffle 20 is fixedly connected to the side of the second positioning frame 19 away from the first positioning frame 15. The side baffle 20 extends from one side of the second positioning frame 19 and fits against the end of the steel plate sample 22.

[0030] As described above, the first positioning frame 15 and the second positioning frame 19 can clamp and fix the steel plate sample 22 under the elastic force of the spring 14. In order to further improve the positioning effect of the first positioning frame 15 and the second positioning frame 19 on the steel plate sample 22, an arc plate 16 is provided on one side of the first positioning frame 15. The arc plate 16 has a circular arc contour and is located on the outside of the first positioning frame 15. When the worker holds the steel plate sample 22 and approaches the first positioning frame 15, the steel plate sample 22 will squeeze the first positioning frame 15 and automatically move backward to avoid the steel plate sample 22 under the guiding action of the circular arc contour of the arc plate 16, so that the steel plate sample 22 can pass directly through the first positioning frame 15.

[0031] Furthermore, a side baffle 20 is installed on the second positioning frame 19. The side baffle 20 is perpendicular to the end face of the second positioning frame 19. This arrangement creates a 90-degree angle between the end faces of the side baffle 20 and the second positioning frame 19. When the operator pushes one end of the steel plate sample 22 to the position of the side baffle 20, the side baffle 20 not only blocks the steel plate sample 22 to inform the operator that the position of the steel plate sample 22 has been completed, but also positions the end of the steel plate sample 22 so that when the end of the steel plate sample 22 abuts against the side baffle 20, the notch on the steel plate sample 22 is exactly located at the center of the two supports 2. The operator does not need to use a "centering template" to observe and judge the position of the notch. This arrangement not only improves the efficiency of placing the steel plate sample 22, but also ensures the accuracy of the placement position of the steel plate sample 22, thereby improving the accuracy of the equipment testing.

[0032] Furthermore, pull plates 17 are installed on the outer sides of both the first positioning frame 15 and the second positioning frame 19. The pull plates 17 allow workers to manually pull the first positioning frame 15 and the second positioning frame 19 to change their positions. In addition, the first positioning frame 15, the arc plate 16, the pull plate 17 and the slide plate 18, as well as the second positioning frame 19, the side baffle 20, the pull plate 17 and the slide plate 18 are all integrally formed sheet metal structures. In actual production, they are integrally injection molded using a mold. This structural design makes the positioning mechanism production process simple and the manufacturing cost low.

[0033] The working principle of the technical solution provided by this invention is as follows: In use, the operator adjusts the rotating lever 6 through the control mechanism 4, causing the lever 6 to rotate to the locking mechanism 9 position under the drive of the drive mechanism 5. Then, the locking mechanism 9 locks and fixes the lever 6. After the lever 6 is fixed, the operator holds the steel plate sample 22 and inserts it between the front baffle 11 and the first positioning frame 15 with the notched side of the steel plate sample 22 against the inner wall of the front baffle 11. During the insertion process, the steel plate sample 22 will be squeezed by the arc-shaped contour of the arc plate 16 under the guidance of the first positioning frame 15. Positioning bracket 15 automatically moves backward to avoid the steel plate sample 22, allowing the steel plate sample 22 to pass directly through the first positioning bracket 15. When the end face of the steel plate sample 22 is pushed to the position of the side baffle 20, the side baffle 20 not only blocks the steel plate sample 22 to inform the staff that the position of the steel plate sample 22 has been completed, but also positions the end of the steel plate sample 22 so that when the end of the steel plate sample 22 abuts against the side baffle 20, the notch on the steel plate sample 22 is exactly located between the two supports. At the center of seat 2, there is no need for staff to use a "centering template" to observe and judge the position of the notch. This setting not only improves the efficiency of placing the steel plate sample 22, but also ensures the accuracy of the placement position of the steel plate sample 22. After the steel plate sample 22 is placed, the spring force of spring 14 can apply a clamping force to the steel plate sample 22. Under the action of the clamping force, the steel plate sample 22 is clamped and fixed between the front baffle 11 and the second positioning frame 19 and the first positioning frame 15. This setting can improve the stability of the steel plate sample 22 after placement, thereby avoiding the positional deviation of the steel plate sample 22 due to equipment shaking or collisions by staff, and improving the accuracy of the measurement data of the testing equipment. After the steel plate sample 22 is fixed on the top of the support 2, the staff can use the control mechanism 4 to operate the locking mechanism 9 to release the fixing effect on the swing arm 6. At this time, the swing arm 6 will swing towards the steel plate sample 22 and impact the steel plate sample 22. The value generated by the pendulum 7 impacting the steel plate sample 22 will be displayed on the scale 8 for easy observation and recording by the staff.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
