Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning manufacturing, in particular to an air-conditioning pipeline pressure plate detection tool. Background Art

[0002] During the production process of air conditioners, the air conditioning pipe pressure plate plays an important role in fixing and protecting the pipes. Its quality and installation accuracy directly affect the performance and reliability of the air conditioner. However, the current inspection of air conditioning pipe pressure plates and pressure plate joints mostly relies on manual visual inspection and simple manual measuring tools. This inspection method is inefficient, inaccurate and prone to human errors. In order to better connect the pressure plate joints and air conditioning pipes, the pressure plate needs to be inspected by inspectors after production to avoid deviations in the installation holes or hole diameters that do not meet the requirements.

[0003] For example, Chinese patent CN216925947U discloses a special-shaped pressure plate inspection tool for air-conditioning pipelines, including a mounting block, a blocking column, a sealing assembly and a fixing assembly; the mounting block is provided with a clearance hole for the connecting screw to pass through; the blocking column is connected to the mounting block, and the axial direction of the blocking column is parallel to the axial direction of the clearance hole, and the blocking column is used to be inserted into the vent; the sealing assembly is connected to the blocking column, and the sealing assembly is used to block the gap between the blocking column and the inner wall of the vent; the fixing assembly is connected to the mounting block, and the fixing assembly is used to fix the special-shaped pressure plate.

[0004] The existing inspection tooling usually uses an inspection ruler to inspect the installation hole position of the pressure plate joint. During the inspection process, the pressure plate is prone to position displacement, and this inspection method is prone to produce errors of a certain angle, and the inspection efficiency is low. The existing air-conditioning pipeline pressure plate inspection tooling cannot meet the production requirements of air-conditioning pipeline pressure plates. To address the above problems, an air-conditioning pipeline pressure plate inspection tooling is proposed. Utility Model Content

A through hole 13 is opened through the top of the detection platform 11, and a slide groove 12 is opened through one end of the top of the detection platform 11. The two sides of the movable seat 18 are slidably connected to the inner side of the slide groove 12. The interior of the detection platform 11 is fixedly connected to a limit cylinder 112, and a piston rod 113 is provided on the top of the limit cylinder 112, and a limit protrusion 114 is fixedly installed on the top of the piston rod 113.

[0023] The following is a detailed description of the specific settings and functions of this embodiment: the fixing mechanism 1 is composed of a limiting protrusion 114, a clamping plate 110 and a rubber pad 111. The rubber pad 111 can avoid damage to the pressure plate during clamping, and can limit and clamp the pressure plate to be tested. At the same time, the mounting hole of the pressure plate to be tested is located in the detection position. The fixing mechanism 1 can quickly and accurately fix the air-conditioning pipe pressure plate to avoid displacement of the pressure plate position during the detection process.

[0024] Example 2: Figure 1 、 Figure 2 and Figure 4As shown, the hole position detection mechanism 2 includes a lifting cylinder 22, a support plate 23, a positioning probe 26, a protective shell 27 and a vertical pipe 210. The bottom end of the lifting cylinder 22 is fixedly connected to the top of the support plate 23, the top of the support plate 23 is fixedly installed with a microprocessor 25, the top of the protective shell 27 is fixedly connected to the bottom of the microprocessor 25, the top of the vertical pipe 210 is fixedly connected to the top wall of the protective shell 27, and the inner wall of the vertical pipe 210 is slidably connected to the outer wall of the top end of the positioning probe 26, the inside of the protective shell 27 is fixedly connected to a pressure sensor 28, and one end of the pressure sensor 28 is fixedly connected to a probe 29, one end of the probe 29 passes through the vertical pipe 210 and extends into the interior of the vertical pipe 210, the top of the lifting cylinder 22 is fixedly installed with a support frame 21, the bottom end of the support frame 21 is fixedly installed with the top of the detection platform 11, the two ends of the support frame 21 are symmetrically fixedly connected to the limit rod 24, and the inner wall of one end of the support plate 23 is slidably connected to the outer wall of the limit rod 24.

[0025] The effect achieved by the entire embodiment is that the hole position detection mechanism 2 adopts the combination of the positioning probe 26 and the pressure sensor 28. When the positioning probe 26 is inserted into the mounting hole, the pressure sensor 28 detects the resistance change during the insertion process through the probe 29. If there is a deviation in the mounting hole position or the hole diameter does not meet the requirements, the pressure sensor 28 will output an abnormal signal to the microprocessor 25, thereby judging the accuracy of the mounting hole position and quickly and accurately detecting the hole position accuracy of the air-conditioning pipe pressure plate.

[0026] The usage and working principle of this device: When the device detects the hole position of the pressure plate joint of the air-conditioning pipeline, first select the limiting protrusion 114 and the positioning probe 26 of the appropriate diameter according to the aperture of the hole to be measured, install the limiting protrusion 114 at the top position of the piston rod 113, and open the limiting cylinder 112 through the controller. The limiting cylinder 112 drives the limiting protrusion 114 to move upward through the piston rod 113 until the limiting protrusion 114 passes through the through hole 13 and reaches the top of the detection platform 11. At this time, the pressure plate to be measured is placed on the detection platform 11, and the limiting protrusion 114 passes through the hole position of the pressure plate. At this time, the clamping motor 14 is turned on by the controller, and the clamping motor 14 drives the driving gear 15 to rotate, thereby rotating the driven gear 16 and the screw rods 17 at both ends, so that the movable seat 18 and the fixed plate 19 slide along the slide groove 12, and the driving gear is controlled by the clamping motor 14 The rotation direction of 15 can make the two fixing plates 19 move in opposite directions (move towards each other or move away from each other). At this time, the two fixing plates 19 move towards each other along the detection platform 11 and approach the pressure plate to be tested until the two clamping plates 110 clamp the pressure plate to be tested. Through the combination of the limiting protrusion 114, the clamping plate 110 and the rubber pad 111, the rubber pad 111 can avoid damage to the pressure plate during clamping, and can limit and clamp the pressure plate to be tested. At the same time, the mounting hole of the pressure plate to be tested is located at the detection position (the bottom of the positioning probe 26). The air-conditioning pipeline pressure plate can be quickly and accurately fixed by the fixing mechanism 1, avoiding the position deviation of the pressure plate during the detection process, facilitating the hole position detection mechanism 2 to detect the air-conditioning pipeline pressure plate, and improving the detection efficiency. At the same time, the detection tooling can easily adapt to the hole position detection needs of air-conditioning pipeline pressure plates of different sizes and hole diameters, and has a wide range of applications.

[0027] After the air-conditioning pipe pressure plate is fixed, the limit cylinder 112 drives the limit protrusion 114 to move downward to the bottom of the through hole 13, and the lifting cylinder 22 and the pressure sensor 28 are turned on by the controller. The lifting cylinder 22 drives the support plate 23 and the positioning probe 26 to move vertically downward. The positioning probe 26 and the pressure sensor 28 are matched. The diameter of the positioning probe 26 matches the standard diameter of the mounting hole of the air-conditioning pipe pressure plate. When the positioning probe 26 is inserted into the mounting hole, the pressure sensor 28 detects the change in resistance during the insertion process through the probe 29. If there is a deviation in the mounting hole position or the hole diameter does not meet the requirements, the pressure sensor 28 will output an abnormal signal to the microprocessor 25, thereby judging the accuracy of the mounting hole position. The hole position detection mechanism 2 can quickly and accurately detect the hole position accuracy of the air-conditioning pipe pressure plate, improve detection efficiency and accuracy, reduce human errors, and ensure the quality of air-conditioning products.
