Description

Technical Field

[0001] This utility model belongs to the field of motor housing testing technology, and in particular relates to a motor housing explosion-proof pressure resistance testing device. Background Technology

[0002] In the production and processing of motors, it is often necessary to use a casing to protect the internal components of the motor. Common motor casings are often made of aluminum alloy, and the surface of the casing is mostly made of heat dissipation fins. Although aluminum alloy casings have a certain pressure resistance, they need to undergo pressure resistance testing after they are manufactured before they can be put into use.

[0003] Existing pressure resistance testing methods mainly involve applying external force to the motor casing and observing whether the casing deforms or is damaged under a fixed pressure. However, there are various models and specifications of motors, and the motor needs to be fixed when performing pressure resistance testing. General testing equipment can often only perform specialized testing on one type of motor. Utility Model Content

[0004] This utility model provides a motor housing explosion-proof pressure resistance testing device, which aims to solve the problem that general testing equipment can often only perform specialized tests on motors of one specification.

[0005] This utility model is implemented as follows: an explosion-proof pressure-resistant testing device for motor housing, including a base and two mounting mechanisms, both of which are disposed on the base and are symmetrically arranged about the centerline of the base in the length direction.

[0006] The mounting mechanism includes a transverse groove that extends vertically along the length of the base and is formed on one side of the upper surface of the base. A threaded rod is laterally rotatably connected to the middle of the inner surface of the transverse groove. A threaded sleeve is threadedly connected to the outer surface of the threaded rod. A slider adapted to the length of the transverse groove is laterally slidably connected inside the transverse groove along the width of the base. A through groove adapted to the threaded sleeve is formed laterally through the middle of the side surface of the slider. The threaded sleeve is vertically slidably connected inside the through groove. Bolt slots are formed vertically along the length of the base on the upper surface of the slider and at both ends of the threaded rod.

[0007] Preferably, the bottom end of the bolt groove is expanded outward to form a recessed groove.

[0008] Preferably, the two ends of the two threaded rods are rotatably connected to the two side surfaces of the base and extend outward, and the outer surfaces of the two threaded rods and located on the outer side of the base are fixedly connected to a torsion block.

[0009] Preferably, extension blocks are fixedly connected to both ends of both sides of the base, and uprights are fixedly connected to the upper surfaces of the multiple extension blocks, with a top plate fixedly connected to the top of the multiple uprights laterally.

[0010] Preferably, the top plate has multiple vertically extending mounting holes in the middle of its upper surface, and each mounting hole has a hydraulic rod fixedly connected vertically inside, with a lower pressure plate fixedly connected to the bottom end of each hydraulic rod.

[0011] Preferably, the outer surfaces of the plurality of uprights are vertically slidably connected with guide sleeves, and the plurality of guide sleeves are fixedly connected to the side surface of the lower pressure plate. Beneficial effects

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: an explosion-proof pressure-resistant testing device for motor housing, including a base 1 and two mounting mechanisms. Both mounting mechanisms are set on the base 1 and are symmetrically arranged about the center line of the length direction of the base 1.

[0020] Both mounting mechanisms have the same structure, specifically including a transverse groove 2 that is vertically opened along the length of the base 1 on one side of the upper surface of the base 1. A threaded rod 3 is laterally rotatably connected to the middle of the inner surface of the transverse groove 2. A threaded sleeve 4 is threadedly connected to the outer surface of the threaded rod 3. A slider 5 that is adapted to the length of the transverse groove 2 is laterally slidably connected to the inside of the transverse groove 2 along the width of the base 1. A through groove 15 that is adapted to the threaded sleeve 4 is laterally opened in the middle of the side surface of the slider 5. The threaded sleeve 4 is vertically slidably connected to the inside of the through groove 15. Bolt grooves 7 that are set along the length of the base 1 are vertically opened on the upper surface of the slider 5 and at both ends of the threaded rod 3.

[0021] In this embodiment, the mounting mechanism of the device can adjust the position of the slider 5 according to the actual motor model being tested. When the position of the slider 5 needs to be adjusted, the threaded rod 3 is rotated, and the threaded rod 3 drives the threaded sleeve 4 to move along its length direction, thereby synchronously driving the slider 5 to move along the width direction of the base 1, adjusting the multiple bolt slots 7 to the appropriate position. Since the bolt slots 7 are set along the length direction of the base 1, the device can be adapted to motors of various specifications and models.

[0022] Furthermore, the bottom ends of multiple bolt grooves 7 are all expanded outward to form sinkholes.

[0023] In this embodiment, the groove prevents the bottom bolt from protruding from the lower surface of the slider 5.

[0024] Furthermore, the two ends of the two threaded rods 3 are rotatably connected to the two side surfaces of the base 1 and extend outwards, and the outer surfaces of the two threaded rods 3 and located on the outside of the base 1 are fixedly connected to the torsion blocks 8.

[0025] In this embodiment, the torsion block 8 facilitates the rotation of the threaded rod.

[0026] Furthermore, guide rods 6 are fixedly connected to both ends of the transverse groove 2 in the horizontal direction, and sliding holes corresponding to and adapted to the guide rods 6 are opened through both ends of the slider 5 in the horizontal direction. The slider 5 is slidably connected to the outer surface of the two guide rods 6 through the two sliding holes.

[0027] In this embodiment, the guide rod 6 serves to guide and support, ensuring that the slider 5 does not deviate or otherwise deviate.

[0028] Furthermore, extension blocks 9 are fixedly connected to both ends of the two sides of the base 1, and uprights 10 are fixedly connected vertically to the upper surfaces of the multiple extension blocks 9, and top plates 11 are fixedly connected horizontally to the top ends of the multiple uprights 10.

[0029] Multiple mounting openings are vertically through the middle of the upper surface of the top plate 11. Each mounting opening is vertically fixed with a hydraulic rod 12, and the bottom end of each hydraulic rod 12 is horizontally fixed with a lower pressure plate 13.

[0030] In this embodiment, after the motor is fixed, the extension of multiple hydraulic rods 12 can drive the lower pressure plate 13 to descend, and the lower pressure plate 13 can be used to perform a pressure test on the motor housing.

[0031] Furthermore, guide sleeves 14 are vertically slidably connected to the outer surfaces of multiple uprights 10, and multiple guide sleeves 14 are fixedly connected to the side surfaces of the lower pressure plate 13.

[0032] In this embodiment, the guide sleeve 14 can guide and limit the lower pressure plate 13 so that it always remains in a horizontal state.

[0033] The working principle and usage process of this utility model: After the utility model is installed, the installation mechanism of the device can adjust the position of the slider 5 according to the actual motor model being tested. When it is necessary to adjust the position of the slider 5, rotate the threaded rod 3. The threaded rod 3 drives the threaded sleeve 4 to move along its length direction, thereby synchronously driving the slider 5 to move along the width direction of the base 1, adjusting the multiple bolt slots 7 to the appropriate position. At the same time, because the bolt slots 7 are set along the length direction of the base 1, the device can be adapted to motors of various specifications and models.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
