Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure resistance testing devices, and in particular to a pressure resistance testing device for die-cast boxes that is easy to observe. Background Technology
[0002] Die-cast enclosures refer to metal shells or packages manufactured through a die-casting process, commonly used in the automotive, machinery, and electronics industries. They typically utilize lightweight metal materials such as aluminum alloys, magnesium alloys, and zinc alloys. With the increasing demand for aluminum alloy and other lightweight alloy enclosures in the automotive, machinery, and electronics industries, ensuring their structural strength and compressive strength has become crucial.
[0003] Currently, existing compressive strength testing methods involve placing the die-cast housing directly on a platform and using a pressure-applying assembly at the top to conduct a pressure test. However, placing the die-cast housing directly on the platform during pressure testing may cause it to slip and shift, leading to inaccurate test results. Furthermore, existing testing equipment presents inconvenient data acquisition challenges. Therefore, those skilled in the art have proposed a more easily observable compressive strength testing device for die-cast housings to address the problems mentioned in the background section. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easy-to-observe pressure testing device for die-cast boxes. This device can assist in clamping and fixing the outer walls of die-cast boxes of different sizes, improve the stability of the pressure testing process, and facilitate data reading.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A pressure resistance testing device for a die-casting box that is easy to observe includes a base, a top plate fixedly mounted on the upper surface of the base, a hydraulic rod fixedly mounted at the midpoint of the upper surface of the top plate, an extrusion plate fixedly mounted at the lower output end of the hydraulic rod, auxiliary fixing components for auxiliary clamping of the die-casting box installed on both sides of the inner wall of the base, and a pressure sensor embedded between the two auxiliary fixing components at the midpoint of the upper surface of the base.
[0007] Furthermore, the lower output end of the hydraulic rod penetrates the lower end face of the top plate, and the extrusion plate is located between the two sides of the inner wall of the base.
[0008] Furthermore, the auxiliary fixing assembly includes two telescopic rods and a clamping plate. The two telescopic rods are respectively fixedly installed at the front and rear ends of one side of the outer wall of the clamping plate, and the other end of the telescopic rod is fixedly connected to the side wall of the base. A screw is rotatably connected to the midpoint of the outer wall of the side of the clamping plate connected to the telescopic rod through a bearing. The screw is threadedly sleeved with the side wall of the base.
[0009] Furthermore, a sliding groove is provided at the midpoint of the outer wall on the other side of the clamping plate, and a second screw is rotatably installed in the sliding groove. Both ends of the second screw are threaded with linkage blocks, and clamping blocks are fixedly installed on one side of the outer wall of both linkage blocks.
[0010] Furthermore, one end of the second screw passes through the front end face of the clamping plate and is fixedly provided with a torsion block, and a ruler plate is fixedly provided at both the front and rear ends of the upper end of the clamping plate.
[0011] Furthermore, the pressing plate above the ruler plate has positioning holes corresponding to the upper and lower parts of the ruler plate.
[0012] Furthermore, the base adopts an upward-facing U-shaped structure, and the pressure sensor is connected to a display terminal.
[0013] This utility model has the following beneficial effects:
[0014] 1. The present invention proposes a pressure resistance testing device for die-casting boxes that is easy to observe. By setting auxiliary fixing components on both sides of the upper end of the base, the auxiliary fixing components can be adapted to the size and specifications of the die-casting box to achieve the auxiliary clamping and fixing effect of the die-casting box, avoiding the displacement and shaking of the die-casting box during pressure resistance testing, and improving the stability of the test.
[0015] 2. The present invention proposes a pressure resistance testing device for die-cast boxes that is easy to observe. By adding a vertical ruler plate for measuring displacement distance on the auxiliary fixing component, the ruler plate is provided with accurate scale numbers. When conducting pressure resistance testing on the die-cast box, the pressure distance can be read according to the ruler plate, and the applied pressure can be read according to the pressure sensor, thereby facilitating the reading of the penetration pressure value and the deformation displacement value of the box.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figure 1 An embodiment of this utility model provides a pressure resistance testing device for a die-casting box that is easy to observe. It includes a base 5, a top plate 2 fixedly installed on the upper surface of the base 5, a hydraulic rod 1 fixedly installed at the midpoint of the upper surface of the top plate 2, an extrusion plate 8 fixedly installed at the lower output end of the hydraulic rod 1, auxiliary fixing components 4 for auxiliary clamping of the die-casting box installed on both sides of the inner wall of the base 5, a pressure sensor 6 embedded between the two auxiliary fixing components 4 at the midpoint of the upper surface of the base 5, the base 5 adopts an upward-facing U-shaped structure, and the pressure sensor 6 is connected to a display end.
[0024] Specifically, the hydraulic rod 1 is used to press down the extrusion plate 8 to perform a pressure test on the die-casting box placed below, thus completing the pressure resistance test of the die-casting box. The pressure sensor 6 on the base 5 can detect the pressure applied to the die-casting box when it is placed on the base 5, which is convenient and quick to read.
[0025] Reference Figure 1 The lower output end of the hydraulic rod 1 passes through the lower end face of the top plate 2, and the extrusion plate 8 is located between the two sides of the inner wall of the base 5.
[0026] Specifically, the extrusion plate 8 always moves vertically up and down on the upper part of the base 5, and the outer walls on both sides play an auxiliary limiting role, while also having a certain protective function.
[0027] Reference Figures 2-4 The auxiliary fixing component 4 includes two telescopic rods 402 and a clamping plate 403. The two telescopic rods 402 are respectively fixedly installed at the front and rear ends of one side of the outer wall of the clamping plate 403, and the other end of the telescopic rods 402 is fixedly connected to the side wall of the base 5. A screw 401 is rotatably connected to the midpoint of the outer wall of the side of the clamping plate 403 connected to the telescopic rods 402 through a bearing. The screw 401 is threadedly connected to the side wall of the base 5.
[0028] Specifically, during use, by twisting the No. 1 screw 401 to rotate it, it moves to one side along the outer wall of the base 5. Since one end of the No. 1 screw 401 is rotatably connected to the clamping plate 403, and the clamping plate 403 is restricted by the two telescopic rods 402 at the front and rear ends, the clamping plate 403 will not rotate. Finally, under the push of the No. 1 screw 401, the auxiliary extrusion and fixing effect on the outer wall of the die-casting box is achieved.
[0029] Reference Figures 2-4 A sliding groove 7 is provided at the midpoint of the outer wall on the other side of the clamping plate 403. A second screw 408 is rotatably installed in the sliding groove 7. A linkage block 407 is threadedly connected to the front and rear ends of the second screw 408. A clamping block 405 is fixedly installed on one side of the outer wall of the two linkage blocks 407.
[0030] Specifically, by twisting the second screw 408 to rotate, the second screw 408 is a double-ended screw with two linkage blocks 407 threadedly connected to the front and rear ends of the double-ended screw. During the rotation of the double-ended screw, the relative displacement of the two linkage blocks 407 is completed, thereby achieving the auxiliary clamping and fixing effect in the front and rear directions.
[0031] Reference Figures 2-4 One end of the second screw 408 passes through the front end face of the clamping plate 403 and is fixedly provided with a torsion block 404. The front and rear ends of the upper end of the clamping plate 403 are fixedly provided with ruler plates 406. The pressing plate 8 above the ruler plate 406 is provided with positioning holes 3 corresponding to the upper and lower ends of the ruler plate 406.
[0032] Specifically, the torsion block 404 designed at the front end of the second screw 408 makes it easy for users to twist by hand, making it more convenient to use; while the ruler plate 406 at the upper end has a scale on its front surface. When the upper extrusion plate 8 moves to the upper surface of the die-casting box, the current scale value is recorded. Then, when pressure is applied for pressure resistance testing, the deformation is judged according to the change of the scale value, which is convenient for users to observe and read.
[0033] Working principle: When in use, the die-casting box is first placed on the upper part of the base 5 between the two auxiliary fixing components 4. Then, by turning the first screw 401, it is rotated to move to one side along the outer wall of the base 5 and push the clamping plate 403 to complete the auxiliary squeezing and fixing effect on the outer wall of the die-casting box. Meanwhile, turning the second screw 408 completes the relative displacement of the two linkage blocks 407, thereby achieving the auxiliary clamping and fixing effect in the front and rear directions.
[0034] After the auxiliary clamping and fixing of the die-casting box is completed, the upper hydraulic rod 1 is used to push the lower extrusion plate 8 to perform a downward pressure test on the upper end of the die-casting box. The pressure reading is obtained from the pressure sensor 6 on the base 5 and the displacement deformation is read from the scale on the ruler 406.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
