[0002] Casting products are products made through a metal heat treatment process called casting. Generally, liquid metal is poured into a casting cavity that conforms to the shape of the part. After cooling and solidification, the part or blank is obtained. Die casting is a type of pressure casting. Using a pressure casting machine equipped with a casting mold, molten metal such as copper, zinc, aluminum, or aluminum alloy is poured into the feed inlet of the die casting machine. The machine then presses and casts copper, zinc, aluminum, or aluminum alloy parts of the shape and size specified by the mold. Die casting is an important component of motors. During production, to ensure the normal operation of the motor, the strength of the castings needs to be tested; therefore, a motor casting strength testing device is required.

[0003] Existing strength testing equipment for motor castings has several drawbacks. It is inconvenient to test the strength at different locations on the casting, the stability of the casting is not high enough, and the assessment of the strength performance of the casting is not accurate enough.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] like Figures 1 to 4 As shown, this motor casting strength testing equipment includes a worktable 1. A threaded adjusting rod 2 is installed on the inner wall of the worktable 1, a first drive motor 3 is installed on the outer wall of the threaded adjusting rod 2, a placement platform 4 is installed on the outer wall of the threaded adjusting rod 2, and a first slider 5 is installed on the side wall of the placement platform 4. The threaded adjusting rod 2 is movably connected to the worktable 1, and the threaded adjusting rod 2 forms a rotating structure with the worktable 1 through the first drive motor 3. The placement platform 4 is threadedly connected to the threaded adjusting rod 2, and the placement platform 4 forms a sliding structure with the worktable 1 through the first slider 5. When using the device, the first drive motor 3 is started to drive the threaded adjusting rod 2 to rotate. Under the drive, the first slider 5 drives the placement platform 4 to move left and right on the worktable 1, so that the casting moves left and right, which facilitates the testing of the strength at different positions on the casting.

[0026] The device includes an electric push rod 6 mounted on the side wall of the placement platform 4, a fixing plate 7 mounted on the side wall of the electric push rod 6, a bidirectional threaded rod 8 mounted on the inner wall of the fixing plate 7, a second drive motor 9 mounted on the outer wall of the bidirectional threaded rod 8, and a clamping plate 10 mounted on the outer wall of the bidirectional threaded rod 8. A detector 11 is mounted on the top of the worktable 1. The bidirectional threaded rod 8 and the fixing plate 7 form a rotating structure through the second drive motor 9, and the fixing plate 7 and the placement platform 4 form a telescopic structure through the electric push rod 6. The clamping plate 10 is set around the central axis of the fixing plate 7 and is threadedly connected to the bidirectional threaded rod 8. When using the device, the electric push rod 6 is activated to move the fixing plates 7 on both sides closer together to fix the left and right sides of the casting. Then, the second drive motor 9 is activated to rotate the bidirectional threaded rod 8, and the clamping plates 10 on both sides move closer together to fix the upper and lower sides of the casting, thereby improving the stability of the casting.

[0027] To further explain, such as Figure 4 As shown, a heating box 12 is installed on the inner wall of the placement platform 4, a buckle 13 is installed on the outer wall of the heating box 12, a second slider 14 is installed on the side wall of the heating box 12, a fan 15 is installed on the inner wall of the heating box 12, a heating wire 16 is installed on the inner wall of the heating box 12, and a filter screen 17 is installed on the top of the heating box 12. The heating box 12 and the placement platform 4 form a sliding structure through the second slider 14, and the inner wall of the placement platform 4 is slotted. The heating wire 16 is symmetrically arranged around the central axis of the heating box 12, and the heating... The chamber 12 is engaged with the workbench 1. When using the device, the fan 15 blows air upwards, and the heating wires 16 on both sides heat the air blown by the fan 15 and heat the casting to test the strength of the casting at different temperatures, so as to more accurately evaluate the strength performance of the casting. At the same time, the filter screen 17 can prevent debris from entering the fan 15. When the internal components of the heating chamber 12 need to be replaced or maintained, simply unlock the buckles 13 on both sides of the heating chamber 12 and then pull the heating chamber 12 outwards.

[0028] When using this motor casting strength testing equipment, first move the device to a suitable position, then place the casting to be tested on the placement platform 4. Next, activate the electric push rod 6 to push the two fixing plates 7 closer together, securing the left and right sides of the casting. Then, activate the second drive motor 9 to rotate the bidirectional threaded rod 8, moving the two clamping plates 10 closer together to secure the top and bottom sides of the casting. Then, activate the fan 15 and heating wire 16. The heating wire 16 converts the air blown by the fan 15 into hot air, heating the casting at different temperatures. Simultaneously, the filter screen 17 prevents debris from entering the fan 15. The casting is then inspected using detector 11. When it is necessary to test the strength of different positions on the casting, simply start the first drive motor 3 to drive the threaded adjusting rod 2 to rotate, and drive the placement table 4 to slide left and right on the worktable 1 through the first slider 5, thereby moving the casting. When it is necessary to replace or maintain the internal components of the heating box 12, simply unlock the buckles 13 on both sides of the heating box 12 that are fixed on the placement table 4, and then pull the heating box 12 outward to remove it. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
