Description

Technical Field

[0001] This utility model belongs to the field of cylinder block detection technology, specifically relating to a comprehensive position detection device for an air conditioning compressor cylinder block. Background Technology

[0002] As the "heart" of a modern air conditioning system, the performance of the air conditioning compressor directly determines the overall cooling efficiency and operational reliability of the unit. The compressor exchanges heat by compressing low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure state, driving a refrigeration cycle. In this precise energy conversion process, the cylinder, as the core component of the compressor, not only forms the compression chamber for the working medium, but its structural precision also directly affects the overall energy efficiency, vibration and noise levels, and service life of the unit.

[0003] The relative positional accuracy of characteristic structures such as threaded holes, rivet holes, spring holes, and suction ports distributed on the cylinder end face is a key factor in ensuring the precise assembly of various compressor components. Deviations in the relative positions of these hole systems will cause changes in the fit clearances of critical components such as valve plates and cylinders during assembly, leading to a chain reaction of refrigerant leakage, abnormal wear, and other problems. Therefore, precise positional detection of various hole systems during manufacturing is a crucial aspect of quality control.

[0004] Currently, the industry commonly employs a combined inspection solution using image measuring instruments (EMAs) and coordinate measuring machines (CMMs): the EMA detects the relative positions of end face holes, while the CMM's rotating probe performs the positioning measurements of spatial hole systems such as spring holes and air intake holes. While this solution meets accuracy requirements, it has significant limitations: the use of multiple devices complicates the inspection process, CMM positioning requires manual intervention, and the inspection cycle can take tens of minutes. In high-paced automated production environments, this discrete inspection method has become a bottleneck restricting production efficiency, making it difficult to achieve real-time feedback and process control of quality data.

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, one aspect of this utility model is to provide a comprehensive position detection device for an air conditioning compressor cylinder block. The detection device includes a base plate, a side hole detection component, and an end hole detection component. The side hole detection component and the end hole detection component are disposed on the same plane as the base plate. The side hole detection component includes a guide seat, a first internally threaded cylindrical pin, a side hole plug gauge, and a side hole plug gauge hole. The end hole detection component includes a positioning plate, a second internally threaded cylindrical pin, a detection hole, and a detection pin. The guide seat is fixedly connected to the base plate via the first internally threaded cylindrical pin. The side hole plug gauge hole is disposed on the guide seat, and the direction of the side hole plug gauge hole is horizontal to the guide seat. The side hole plug gauge is movably disposed within the side hole plug gauge hole. The positioning plate is fixedly connected to the base plate via the second internally threaded cylindrical pin. The detection hole is disposed on the positioning plate, and the direction of the detection hole is perpendicular to the guide seat. The detection pin is movably disposed within the detection hole.

[0006] Preferably, the base plate further includes a foot, which is threadedly connected to the base plate and fixedly mounted on the base plate. The foot is located on the opposite side of the side hole detection component and the end hole detection component.

[0007] Preferably, the side hole detection assembly includes a positioning hole and a cylindrical end set screw. The positioning hole is located at the end of the guide seat away from the base plate. The positioning hole is perpendicular to the side hole plug gauge. The positioning hole communicates with the side hole plug gauge hole. The cylindrical end set screw is screwed into the positioning hole. The length of the cylindrical end set screw is greater than the depth of the positioning hole.

[0008] Preferably, the side hole plug gauge includes a positioning groove, which is disposed on the side hole plug gauge. The positioning groove is positioned horizontally to the side hole plug gauge hole and is oriented towards the positioning hole.

[0009] Preferably, the positioning groove is an O-shaped groove.

[0011] Preferably, the end face detection assembly further includes a center pin, which is disposed at the center of the positioning plate and is fixedly connected to the positioning plate. The center pin is fixedly connected to the base plate through a third internal thread cylindrical pin, and at least two sets of the third internal thread cylindrical pin are provided.

[0012] Preferably, the end face detection assembly further includes a positioning pin and a rivet avoidance hole detection pin.

The second internal thread positioning pin is provided between the second internal thread cylindrical pins, and the third internal thread positioning pin is provided in two sets of third internal thread cylindrical pins.

[0014] The beneficial effects of this utility model are as follows: Modular design improves operational and warehousing efficiency: The modular design of the inspection device is achieved through the detachable design between the side hole inspection device, end hole inspection device and positioning plate. This design allows the device to be disassembled and stored when not in use, which significantly saves storage space. When in use, it can be quickly assembled and put into inspection, which greatly improves the deployment flexibility and management convenience of the equipment.

[0015] Integrated testing doubles efficiency: The device integrates multiple side hole plug gauges, enabling simultaneous and one-time testing of side holes at different angles. This eliminates the cumbersome process of measuring and repeatedly positioning each hole individually, a traditional method. This integrated testing mode significantly shortens the testing time for a single product, resulting in a significant improvement in overall testing efficiency.

[0016] Multi-functionality and improved equipment utilization and versatility: This integrated device effectively replaces the inspection tasks that previously required multiple specialized inspection equipment (such as imagers, coordinate measuring machines, etc.), achieving "multi-functionality in one machine". This not only reduces the dependence on multiple expensive equipment and procurement costs, but also greatly improves the utilization rate and return on investment of a single device.

[0017] Adjustable structure broadens application range: By adopting a design combining positioning plate and base plate, and allowing for the replacement of positioning plates of different thicknesses, the device can flexibly adapt to changes in the distance between the side hole and the end face of the product. This adjustable and expandable structural design allows one device to cover the testing needs of various product specifications, significantly expanding the applicability of the device and reducing the cost of repeatedly investing in special inspection tools due to changes in product models.

[0018] In summary, this utility model, through its modular, integrated, and adjustable design, has successfully achieved a leap in testing efficiency and optimized equipment utilization, perfectly meeting the urgent needs of modern production sites for efficient, accurate, and flexible testing, and providing strong support for accelerating production pace and controlling costs.
