Description

Technical Field

[0001] The utility model relates to the technical field of sealing detection, in particular to an axial fixed-displacement motor sealing detection device. Background Technique

[0002] A fixed-displacement motor is a hydraulic motor with a constant theoretical output displacement per revolution, having a series of characteristics such as low noise, high efficiency, small volume, light weight, long service life, complete variable forms, low energy consumption, and adaptability to a variety of hydraulic media. After the motor is installed, in order to ensure the normal operation of the motor and meet safety standards, it is necessary to detect the sealing performance of the motor, so a motor sealing detection device will be used. During the use process, the mold will be pressed down by a hydraulic rod. However, the existing motor sealing detection device lacks a protective device on the periphery, which is likely to press the hands of the detection personnel, and the risk factor is relatively high. Moreover, when installing the mold on the existing detection device, screws are generally used to fix the mold. This fixing method is relatively troublesome when replacing, and it is necessary to unscrew the screws for replacement. For this reason, we propose an axial fixed-displacement motor sealing detection device to solve the above problems. Content of the Utility Model

Limit rods 4 are fixedly installed at the four corners of the top of the detection device main body 1, and the limit rods 4 penetrate through the four corners of the pressing plate 5;

[0031] The protection component is installed on both sides of the protective frame 2;

[0032] The fixing component is arranged between the detection device main body 1 and the pressing plate 5.

[0033] The protection component includes a moving plate 6. The moving plate 6 is arranged on both sides of the protective frame 2. Two sets of upper and lower sliding grooves 9 are opened on both sides of the protective frame 2. Two sets of upper and lower sliders 8 are fixedly installed on the side of the moving plate 6 close to the protective frame 2. The sliders 8 are embedded in the sliding grooves 9 and are slidably connected with the sliding grooves 9. One side of the moving plate 6 is hinged with a protection plate 7. According to Figure 2 As shown, by embedding the slider 8 in the sliding groove 9 and being slidably connected with the sliding groove 9, and hinging one side of the moving plate 6 with the protection plate 7, the function of storing the protection plate 7 is realized, and the protection plate 7 can be stored on both sides of the protective frame 2 when the protection plate 7 is not in use.

[0034] Magnets are arranged on the surface of the side of the protection plate 7 away from the moving plate 6. According to Figure 3 As shown, by arranging magnets on the surface of the side of the protection plate 7 away from the moving plate 6, the function that the protection plates 7 can automatically adsorb when the two protection plates 7 are close to each other is realized, which is very convenient when opening and closing the two protection plates 7 and improves the convenience of the device.

[0035] The length of the protection plate 7 is equal to half of the width of the protective frame 2. According to Figure 2 As shown, by the length of the protection plate 7 being equal to half of the width of the protective frame 2, the function that the two protection plates 7 can completely block the front end of the protective frame 2 is realized.

[0036] The fixing component includes a bottom plate 10. There are two sets of bottom plates 10, which are respectively installed on the top of the detection device main body 1 and the bottom of the pressing plate 5 by screws. The two sets of bottom plates 10 are arranged in two symmetrical sets. A mold 11 is arranged on the top of the bottom plate 10, and a motor main body 12 is placed in the mold 11. Slots 14 are opened on both sides of the mold 11. Support plates 13 are fixedly installed on both sides of the top of the bottom plate 10. A handle 15 is arranged on the outside of the support plate 13, and the handle 15 penetrates through the support plate 13. Limit rings 16 are fixedly installed at both ends of one side of the handle 15, and a spring 17 is connected between the limit ring 16 and the support plate 13, and the spring 17 is sleeved outside the handle 15. The other end of the limit ring 16 is fixedly installed with a plug rod 18, and the plug rod 18 is inserted into the slot 14. According to Figure 4As shown, a spring 17 is connected between the limit ring 16 and the support plate 13, and the spring 17 is sleeved outside the handle 15. The other end of the limit ring 16 is fixedly installed with a plug rod 18, and the plug rod 18 is inserted into the slot 14, realizing the function that the limit ring 16 can resist the mold 11 through the elastic force of the spring 17, which is beneficial to improving the convenience of installation.

[0037] The lengths and diameters of the slot 14 and the plug rod 18 are the same. According to Figure 4 As shown, by making the lengths and diameters of the slot 14 and the plug rod 18 the same, the function that the slot 14 and the plug rod 18 fit perfectly is realized, enabling the mold 11 to be more stable and not shake when fixed, and improving the stability during detection.

[0038] Working principle: First, place the mold 11 on the top of the bottom plate 10, then pull the handles 15 on both sides outwards. The handles 15 can drive the limit ring 16 and the plug rod 18 to move outwards simultaneously. The limit ring 16 will squeeze the spring 17. After the mold 11 is completely placed on the bottom plate 10, release the handles 15. The spring 17 will release its elastic force to push the limit ring 16 and the plug rod 18, and the plug rod 18 will be inserted into the slot 14 to fix the mold 11. Then, install another set of molds 11 at the bottom of the pressing plate 5 in the same way. Then, place the motor main body 12 inside the mold 11. Slide the moving plates 6 on both sides of the protective frame 2 forward to make the sliders 8 slide in the sliding grooves 9. After moving to one end of the sliding groove 9, rotate the protective plate 7. The two protective plates 7 will be attracted together due to the magnetic adsorption force. Then, start the hydraulic rod 3. The output end of the hydraulic rod 3 will drive the pressing plate 5 to press downwards, and the two sets of molds 11 will be combined together. At this time, the sealing detection can be carried out through the detection device main body 1. The above is the entire working principle of the present utility model.
