Description

Technical Field

[0001] This utility model relates to the field of copper tube processing technology, and in particular to a copper tube aperture detection device. Background Technology

[0002] Currently, the industry mostly uses manual caliper measurement or go / no-go gauge inspection to inspect the diameter of copper tubes. Manual caliper measurement relies on the operator's experience, which is not only inefficient and difficult to meet the inspection needs of mass production, but also prone to human error due to manual reading, resulting in unstable inspection accuracy. Although go / no-go gauge inspection can quickly determine whether the diameter is qualified, it cannot obtain specific dimensional deviation data of the diameter, which is not conducive to the adjustment and optimization of subsequent production processes. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes a copper tube aperture detection device.

[0004] This utility model discloses a copper pipe aperture detection device, including an equipment cabinet. A lower fixture and a manual lifting module are installed on the top of the equipment cabinet. A copper pipe is fixed inside the lower fixture. An advance and retraction drive cylinder is installed on the drive end of the manual lifting module. The extension and retraction end of the advance and retraction drive cylinder is connected to a baffle. A detection head is installed on the outer end face of the baffle. The outer end of the detection head is provided with a conical head to be inserted into the opening of the copper pipe. A distance sensor is also installed on the top of the equipment cabinet. The distance sensor corresponds to the baffle to detect the distance between the baffle and the detection end of the distance sensor.

[0005] Furthermore, a pressure module is also installed at the top of the equipment cabinet. The pressure module includes a bracket installed at the top of the equipment cabinet, and a pressure drive cylinder is installed at the end of the bracket.

[0006] Furthermore, an upper fixture is installed on the telescopic end of the downward-pressing drive cylinder. The upper fixture is located directly above the lower fixture. The lower fixture and the upper fixture are compatible, and fixture grooves that are compatible with copper tubes are opened on adjacent end faces.

[0007] Furthermore, a workbench is installed at the top of the equipment cabinet, and the lower fixture is installed at the top of the workbench.

[0008] Furthermore, an audible and visual alarm is installed at the top of the equipment cabinet to sound an alarm and light warning when substandard copper pipes are detected.

[0009] Furthermore, the manual lifting module includes a frame body, with a lead screw rotatably connected to the inside of the frame body via a bearing seat. The lead screw is threadedly connected to a screw drum, and the outer end face of the screw drum is connected to a lifting seat. The lifting seat and the frame body are slidably connected via a linear guide rail. The forward and backward drive cylinder is mounted on the surface of the lifting seat, and a handwheel is connected to the top of the lead screw.

[0010] The beneficial effects of this utility model are as follows: By setting an advance and retraction drive cylinder to drive a detection head with a conical head in conjunction with a distance sensor, the copper tube aperture detection can be completed automatically and specific dimensional deviation data can be obtained without manual reading. This not only eliminates the dependence on operator experience and greatly improves detection efficiency to meet the needs of mass production and ensures stable detection accuracy, but also provides a reliable basis for subsequent production process adjustment and optimization based on the obtained deviation data. It effectively makes up for the shortcomings of low efficiency and unstable accuracy of manual caliper measurement and the inability to obtain deviation data by go / no-go gauge detection.

[0018] Reference Figure 1-6This utility model proposes a copper tube aperture testing device, including a cabinet 1. A workbench 10 is horizontally mounted on the top of the cabinet 1. A lower fixture 2 is fixedly mounted at the center of the top of the workbench 10. The top of the lower fixture 2 has a semi-circular fixture groove that perfectly matches the outer contour of the copper tube 11. A wear-resistant rubber pad is adhered to the inner wall of the fixture groove. This not only prevents direct contact between the copper tube 11 and the fixture groove, thus avoiding surface scratches, but also allows for the adaptation and clamping of copper tubes 11 with different diameter deviations within the allowable range through the elastic deformation of the rubber. To further improve the stability of the copper tube 11 during the testing process, a [further details about the device are needed]. There is a pressing module 8, which consists of a bracket 81 and a pressing drive cylinder 82. The pressing drive cylinder 82 is installed vertically downward at the cantilever end of the bracket 81, and the telescopic end of the pressing drive cylinder 82 is coaxially connected to an upper fixture 9. The bottom of the upper fixture 9 is also provided with a semi-circular fixture groove. The fixture groove is the same size as the fixture groove of the lower fixture 2 and is directly opposite to it. When the piston rod of the pressing drive cylinder 82 extends downward, the upper fixture 9 will move downward accordingly, forming a complete circular clamping cavity together with the lower fixture 2, which firmly fixes the copper tube 11 in it, preventing the copper tube 11 from shifting or shaking during the detection process, and ensuring detection accuracy.

[0019] On the top of the equipment cabinet 1, near the lower fixture 2, a manual lifting module 3 is installed. This module includes a frame, a lead screw, a lead drum, a lifting seat, and a handwheel. The frame is vertically fixed to the top of the equipment cabinet 1. Inside, a lead screw is rotatably supported by two bearing seats. The lead screw is threaded to the outside of the lead drum, and the outer end face of the lead drum is fixedly connected to the lifting seat. The lifting seat slides against the frame via linear guides on both sides. The linear guides are high-precision ball bearing guides, which effectively reduce friction during the movement of the lifting seat, ensuring the smoothness and positional accuracy of the lifting action. The forward and backward drive cylinder 4 is horizontally mounted. On the outer side of the lifting seat, the telescopic end faces the copper tube 11, and a baffle 5 is fixedly connected to the end. On the end face of the baffle 5 away from the forward and backward drive cylinder 4, a detection head 6 is coaxially mounted. The outer end of the detection head 6 is designed as a conical head 61. The maximum diameter of the conical head 61 matches the standard hole diameter of the copper tube 11 to be tested. When the piston rod of the forward and backward drive cylinder 4 extends, the conical head 61 will move towards the opening of the copper tube 11. If the hole diameter of the copper tube 11 meets the standard, the conical head 61 can be smoothly inserted into the opening. If the hole diameter is too small, the conical head 61 will be blocked by the opening of the copper tube 11 and cannot be fully inserted.

[0020] To accurately detect the position of the baffle 5 and thus determine whether the diameter of the copper tube 11 is qualified, a distance sensor 7 is installed at the top of the equipment cabinet 1, corresponding to the position of the baffle 5. This sensor uses the laser ranging principle and has a measurement accuracy of ±0.01mm. Its detection end faces the side of the baffle 5 and can detect the distance between the baffle 5 and the sensor detection end in real time. Before the equipment is in normal operation, a standard calibration is performed: a copper tube 11 with a standard diameter is fixed between the upper and lower fixtures. By manually rotating the handwheel of the manual lifting module 3, the height of the lifting seat is adjusted so that the conical head 61 of the detection head 6 is at the same level as the opening of the copper tube 11. Then, the piston rod of the forward and backward drive cylinder 4 is extended. The process continues until the conical head 61 is fully inserted into the opening of the standard copper tube 11. At this point, the distance value detected by the distance sensor 7 is recorded and set as the standard distance value. In subsequent batch testing, for each copper tube 11 to be tested, the same steps are followed to fix and drive the detection head 6 into the tube. The distance sensor 7 will then detect the distance to the baffle 5 again. If the detected value is consistent with the standard distance value or within the allowable error range, the diameter of the copper tube 11 is deemed acceptable. If the detected value is greater than the standard distance value, it indicates that the conical head 61 is not fully inserted, the diameter of the copper tube 11 is too small, and it is deemed unacceptable. An audible and visual alarm is also installed at the top of the equipment cabinet 1. This alarm is electrically connected to the signal output terminal of the distance sensor 7. When the distance value detected by the distance sensor 7 exceeds the acceptable range, a trigger signal is sent to the audible and visual alarm. The alarm then emits a piercing alarm sound and simultaneously illuminates a red warning light, promptly reminding the operator to sort out the unacceptable copper tubes 11, thereby improving testing efficiency and sorting accuracy.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
