Description

Technical Field

[0001] This utility model relates to a testing device for sheet metal and pipe materials, and more particularly to a testing device with a variable scanning angle. Background Technology

[0002] Currently, in the field of ultrasonic testing, encoders are generally fixedly mounted on probe holders. When inspecting plates or pipes, the probe moves parallel to the surface or inner wall of the plate or pipe under manual or automatic drive to perform ultrasonic flaw detection. Because the encoder is fixed, the probe generally moves longitudinally or laterally to achieve front-to-back or left-to-right scanning of the plate or pipe. However, in some specific applications, such as when operating space is limited, the probe needs to move obliquely to achieve a complete scan of the plate or pipe. Existing fixed testing devices cannot meet this testing requirement. Therefore, a new ultrasonic testing device with a variable scanning angle needs to be designed to improve the applicability of the testing device. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a variable scanning angle detection device that can change the scanning angle of the detection device and improve its applicability by allowing the angle between the encoder and the probe holder to be variable.

[0004] The present invention discloses a variable scanning angle detection device, comprising a probe assembly and an encoder assembly. The probe assembly includes a probe holder and a probe mounted on the probe holder. The encoder assembly includes an encoder housing, an encoder body located inside the encoder housing, a first roller connected to the input shaft of the encoder body, and an encoder connector connecting the encoder housing and the probe holder. A connecting shaft is provided on the probe holder. The encoder connector includes a connector body hinged to the encoder housing. A connecting hook is provided at one end of the connector body. The connecting hook includes a fixing part fixed at one end to the connector body, and a movable part connected to the other end of the fixing part. A first locking bolt is provided on the movable part, passing through the movable part and threadedly connected to the fixing part. The connecting shaft is located between the fixing part and the movable part.

[0005] The advantage of this variable scanning angle detection device lies in its probe holder, which features a connecting shaft. The encoder connector includes a connector body hinged to the encoder housing. One end of the connector body has a connecting hook, which includes a fixed part fixed to the connector body at one end and a movable part connected to the other end. The movable part has a first locking bolt threaded to the fixed part. The connecting shaft is positioned between the fixed part and the movable part. The fixed part, movable part, and first locking bolt allow the connector body to rotate around the connecting shaft. The operator can adjust the tightness between the encoder connector and the connecting shaft using the first locking bolt. This allows adjustment of the angle between the encoder and the probe holder to adapt to the workpiece being scanned. This enables the operator to perform left-right and forward-backward scanning as with conventional probes, and also to adjust the encoder angle for oblique translational scanning. In addition, by adjusting the first locking bolt, the operator can loosen the connection between the encoder connector and the connecting shaft. In this way, the encoder can adjust the scanning angle in real time according to the surface shape of the workpiece being scanned, so as to adapt it to the irregular curved surface, thereby improving the applicability of the detection device.

[0006] Furthermore, in the variable scanning angle detection device of this utility model, the probe fixing frame includes a fixed beam, a movable beam and a connecting beam. One end of the connecting beam is fixedly set at the end of the fixed beam, and the other end of the connecting beam passes through the through hole at the end of the movable beam and slides with the movable beam. A second locking bolt for locking the movable beam is also provided on the movable beam, and the connecting shaft is set at the end of the fixed beam.

[0007] The fixed beam, connecting beam, and movable beam form a portal frame for connecting the probe and encoder connectors. The movable beam allows the probe holder to accommodate different probe models, further enhancing its versatility. The second locking bolt secures the movable beam to the connecting beam.

[0008] Furthermore, in this utility model of a variable scanning angle detection device, a probe holder is provided on the probe fixing frame, and the probe is mounted on the probe holder.

[0009] The probe mount design makes it easier for operators to install the probe.

[0010] Furthermore, in this utility model, the variable scanning angle detection device includes a probe base, a probe mounting groove on the bottom surface of the base, a cable transmission port on the top of the probe mounting groove, the probe being installed in the probe mounting groove, and a tightening bolt threaded to the side wall of the base being provided, the end of the tightening bolt contacting the probe.

[0011] The probe mounting slot facilitates probe installation by operators, the cable transmission port facilitates cable routing, and the tightening bolts allow the probe to be firmly pressed against the inner wall of the probe mounting slot, thus securing the probe and enabling the probe mounting slot to accommodate probes of different sizes.

[0012] Furthermore, in this utility model of a variable scanning angle detection device, a probe input port communicating with a probe mounting groove is provided on the front side of the probe base, and a probe baffle is provided on the outer side of the probe input port. The two ends of the probe baffle are fixedly connected to the base body by bolts.

[0013] The probe input port makes it easy for operators to install the probe into the probe mounting slot. The probe baffle limits the probe's position. During installation, tightening the bolts presses the probe firmly against the probe baffle, thus securing the probe.

[0014] Furthermore, in the variable scanning angle detection device of this utility model, roller assemblies are respectively provided on the left and right sides of the probe base. The roller assembly includes a roller mounting plate fixedly connected to the probe base, and a second roller is provided at the bottom end of the roller mounting plate.

[0015] The roller assembly allows the probe assembly to roll on the board surface, thereby reducing friction between the probe assembly and the board and making it easier to move on the board surface.

[0016] Furthermore, in the variable scanning angle detection device of this utility model, a rotating shaft is provided on the encoder housing, a connecting plate is provided on the side of the connecting body, the surface of the connecting plate is provided with a connecting hole adapted to the rotating shaft, and the end of the rotating shaft passes through the connecting hole and is connected to the encoder housing.

[0017] The design of the rotating shaft and connecting plate enables the hinge connection between the connector body and the encoder housing.

[0018] Furthermore, in the variable scanning angle detection device of this utility model, a spring is sleeved on the rotating shaft, and positioning grooves are provided on the surfaces of the encoder housing and the connecting body. The two ends of the spring are respectively set in the positioning grooves on the surfaces of the encoder housing and the connecting body.

[0019] The spring design allows the encoder assembly to make close contact with the plate surface, enabling the first roller to rotate as the detection device moves, which in turn drives the input shaft of the encoder body to rotate, thus achieving encoding. The positioning groove provides positioning for the spring.

[0020] Furthermore, in the variable scanning angle detection device of this utility model, the inner surfaces of the fixed part and the movable part are respectively provided with clamping grooves adapted to the connecting shaft.

[0021] The clamping groove enables the positioning and clamping of the connecting shaft.
