Description

Technical Field

[0001] The utility model belongs to the technical field of compressors, and particularly relates to a core height measuring device for a refrigeration compressor. Background Technique

[0002] During the assembly process of a refrigeration compressor, it is necessary to ensure that the assembly height of the core meets the design requirements, which can avoid interference and collision between the core and other components, thereby preventing shutdown or damage caused by mechanical failures. A reasonable assembly height helps to reduce vibration and noise during the operation of the compressor and improve the stability and reliability of the equipment.

[0003] At present, the height detection of the refrigeration compressor core commonly uses the method of manual detection. When detecting, a reference plane is determined, and the distance from the component to the reference plane is measured by a height detection instrument to obtain the measured value of the assembly height, and the measured value is compared with the design value to judge whether it meets the requirements. However, manual detection has low accuracy, high work intensity, low production efficiency, and there will also be missed detections and quality hidden dangers. Summary of the Invention

[0030] Next, in combination with Figures 1 to 5 , through specific embodiments and their application scenarios, a core height measuring device for a refrigeration compressor provided by an embodiment of the present utility model will be described in detail.

[0031] A core height measuring device for a refrigeration compressor includes a bottom plate 15, and the bottom plate 15 is connected to a first support plate 2 through a plurality of first support rods 1. As Figure 1 and Figure 3 shown, 4 support columns 16 are fixedly connected below the bottom plate 15, and angle steels are fixedly connected to the corners where the support columns 16 are connected to the bottom plate 15, further improving the stability of the measuring device. A first long waist hole 201 is provided at the corner of the first support plate 2, and the end of the first support rod 1 is connected to the first support plate 2 through a bolt. Through the first long waist hole 201, the first support plate 2 can move along the long axis direction of the first long waist hole 201.

[0032] Above the first support plate 2, a second support plate 4 is connected through a plurality of second support rods 3, and a plurality of measuring members 5 are arranged on the second support plate 4. As Figure 2 and Figure 3 shown, the first support plate 2 is fixedly connected to the second support plate 4 through 4 second support rods 3, and a measuring member support 6 is connected to the second support plate 4. The measuring member support 6 is arranged above the second support plate 4. When the measuring member support 6 is located above the second support plate 4, the measuring member 5 is fixedly connected to the measuring member support 6. Three measuring holes 401 are provided on the second support plate 4. Among them, two measuring holes 401 are arranged in parallel, and the other measuring hole 401 is arranged vertically. The measuring holes 401 are correspondingly arranged below the measuring member 5. In some embodiments, the measuring member support 6 can also be fixedly connected to the lower surface of the second support plate 4, and the measuring member 5 fixedly connected to the measuring member support 6 can directly perform measurement. Among them, the measuring member support 6 is in an L shape, and a measuring member 5 is fixedly connected to the vertical part of the measuring member support 6. A second long waist hole 601 is provided on the horizontal part of the measuring member support 6, and two bolts pass through the second long waist hole 601 and are connected to the second support plate 4. Preferably, the measuring member 5 is a displacement sensor, which can measure the displacement of the measuring guide rod 9 in the vertical direction.

[0033] It can be understood that by setting the first long waist hole 201, the movement of the first support plate is facilitated, and the setting of the second long waist hole 601 facilitates the movement of the measuring piece 5. When measuring, the positions of the first support plate 2 and the measuring piece 5 can be adjusted to meet the measurement of the movement assembly height of compressors of different models, thereby further improving the adaptability of the device.

[0034] A change plate 7 is provided on the first support plate 2 below the measuring member 5, and a plurality of measuring guide rods 9 are sleeved on the change plate 7. Figure 3 and Figure 4 As shown, three mounting grooves 701 are arranged on the mold-changing plate 7, and the connecting tube 8 includes a tube body and a connecting plate 801 arranged at one end of the tube body, and the shape of the connecting plate 801 is adapted to the mounting groove 701. The connecting tube 8 passes through the through hole provided in the mounting groove 701 and the connecting plate 801 is placed in the mounting groove 701, and the connecting plate 801 is fixed to the mold-changing plate 7 by bolts. At the same time, the tube body of the connecting tube 8 passes through the first support plate 2. The measuring guide rod 9 is sleeved in the connecting tube 8. The measuring guide rod 9 includes a rod body and a limiting edge 901 arranged at one end of the rod body. When the measuring guide rod 9 is inserted into the connecting tube 8, the limiting edge 901 prevents the measuring guide rod 9 from continuing to fall under the action of gravity. As shown Figure 4 As shown, the mold-changing plate 7 is a convex structure, and a through mounting hole 202 is provided on the first support plate 2. The protruding portion of the mold-changing plate 7 is adapted to the mounting hole 202, and the area of ​​the base portion of the mold-changing plate 7 is larger than the area of ​​the mounting hole 202. The protruding portion of the mold-changing plate 7 is placed in the mounting hole 202, and is fixed to the first support plate 2 by bolts at the base portion. The mold-changing plate 7 is fixed to the first support plate 2 by bolts for easy disassembly. In order to meet the measurement requirements of different compressors, the positions of the mounting grooves 701 of different mold-changing plates 7 are different, so that the positions of the measuring guide rods 9 are different, so as to meet the measurement requirements of different compressors 12.

[0035] A third support plate 10 that can be raised and lowered is provided between the measuring guide rod 9 and the bottom plate 15. Figure 1 , Figure 2 and Figure 5 As shown, four limit blocks 11 are fixedly connected to the upper surface of the third support plate 10, and the limit blocks 11 pass through the connecting plate 1201 at the bottom of the compressor 12, thereby limiting the movement of the compressor 12. Four guide rods 13 are fixedly connected below the third support plate 10, and the guide rods 13 improve the stability of the third support plate 10 when it rises. Among them, the guide rods 13 pass through the bottom plate 15 and can slide up and down. A lifting mechanism 14 is arranged on the bottom plate 15, and the lifting mechanism 14 passes through the bottom plate 15 and is fixedly connected to the bottom plate 15. Optionally, the lifting mechanism 14 can be any one of a pneumatic push rod, an electric push rod and a hydraulic push rod. The lifting and lowering of the third support plate 10 can be achieved by fixing the movable end of the lifting mechanism 14 to the lower surface of the third support plate 10, thereby achieving the lifting and lowering of the compressor 12. In addition, asFigure 5 As shown, a limit seat 17 is also fixedly connected to the bottom plate 15, and the limit seat 17 is located below the third support plate 10. When the third support plate 10 contacts the limit seat 17, the third support plate 17 cannot continue to descend. At the same time, the position of the third support plate 10 when contacting the limit seat 17 can be used as the initial position of the third support plate 10 during measurement.

[0036] When using the measuring device of the utility model to measure the height of the movement, it is necessary to first adjust the position of the measuring guide rod 9 and the measuring piece 5 by moving, so that the measuring piece 5 can measure the displacement of the measuring guide rod 9, and make the measuring guide rod 9 face the measuring point on the movement of the compressor 12. In the initial state, the end faces of the measuring ends 902 of the three measuring guide rods 9 are kept in the same horizontal plane under the action of gravity, and at this time, the third support plate 10 is in the initial position. The compressor 12 is raised by controlling the lifting mechanism 14 until the movement of the compressor 12 contacts the measuring end 902, and the measuring guide rod 9 is displaced upward after contacting the movement.

[0037] It should be noted that the lifting mechanism 14 is electrically connected to the control device, and the lifting height of the lifting mechanism 14 can be set by the control device. Preferably, the bottom of the shell of the compressor 12 is used as the reference surface during measurement, and the distance from the reference surface to the measuring end 902 in the initial state is the lifting height set by the lifting mechanism 14. The distance from the measuring point on the movement to the reference surface is the assembly height measurement value to be measured. Figure 5 As shown, a placement platform 1001 is provided on the third support plate 10 . When the compressor 12 is placed on the placement platform 1001 , the bottom of the outer shell of the compressor 12 contacts the upper surface of the placement platform 1001 , so the reference surface is also the upper surface of the placement platform 1001 .

[0038] When the compressor 12 rises to the highest point of the set height, it is the final state of the measurement. At this time, the movement of the compressor 12 contacts the measuring guide rod 9 and causes it to move upward. The measuring piece 5 measures the displacement value of the measuring guide rod 9 from the initial state to the final state, which is the height measurement value from the measuring point of the movement of the compressor 12 to the reference plane. The measuring piece 5 is electrically connected to the control device, and the control device automatically compares the height measurement value with the pre-set height design value. If the height measurement value is within the range of the height design value, the movement height meets the requirements; if the height measurement value is not within the range of the height design value, the movement height does not meet the requirements and needs to be reassembled.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
