Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to an integrated device for automatic detection of phase angle of DP double-tooth rack. Background Technology

[0002] The automotive steering input shaft has broad application prospects and large usage volume. However, its installation and use requirements are high. It requires that the phase angle of each double-tooth rack tooth surface be consistent during manufacturing to ensure uniform fluctuation clearance during assembly.

[0003] Since the phase angle of the double tooth surface is a spatial rotation angle relationship, it is difficult to measure manually using an angle ruler. Using special inspection tools involves low efficiency in full inspection and there is a risk of missed or incorrect inspections. Special inspection tools can only be used for functional purposes and do not affect differentiation, but they require high precision and cannot meet the measurement requirements. Therefore, normal processing and inspection are based on coordinate measuring machine (CMM). CMM can ensure measurement accuracy, but it takes a long time, has limited resources, and has high investment costs, which affects the rapid adjustment on the double tooth rack processing site. Moreover, if there is a need for rapid product selection, CMM cannot achieve this. Therefore, a detection device that can quickly judge on the production and selection site is needed. To this end, we propose an integrated automatic detection device for the phase angle of DP double tooth rack to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated device for automatic phase angle detection of DP double-tooth rack includes a housing. A support plate is fixedly connected to the inner wall of the housing. A first servo rotation mechanism and a second servo rotation mechanism are fixedly connected to the upper surface of the support plate. An angle sensor and a positioning and leveling mechanism are fixedly connected to the upper surface of the support plate. Two toothed seat bases are fixedly connected to the upper surface of the support plate. A first product fixture is fixedly installed at the output end of the first servo rotation mechanism, and a second product fixture is fixedly installed at the output end of the second servo rotation mechanism. An NG material channel is fixedly installed on the inner wall of the housing, and an angle display is placed on the upper surface of the housing.

[0007] In a further embodiment, the positioning and leveling mechanism includes a linear sliding guide rail, a measuring seat, and a reference surface plate angle gauge.

[0008] In a further embodiment, both the first servo rotation mechanism and the second servo rotation mechanism include a servo rotation driver, a measuring seat, and a reference plane angle gauge.

[0009] In a further embodiment, both the first product fixture and the second product fixture include a three-jaw clamping mechanism, a bearing rotation mechanism, a coupling, and a center.

[0010] In a further embodiment, the NG channel is located below the pallet, and the positioning and leveling mechanism is located in front of the two toothed seats.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This device, through the cooperation of an angle display, a first servo rotation mechanism, a second servo rotation mechanism, a positioning and leveling mechanism, and an angle sensor, facilitates rapid measurement, reduces measurement waiting time, and improves measurement efficiency. The measurement results of each workpiece can be displayed on the angle display without the need for a series of complex calculations. The measurement operation is faster and simpler than coordinate measuring machine (CMM), eliminating the need for manual measurement by operators, reducing the risk of manual judgment, and avoiding false detections and missed detections. The operator only needs to place the material cart full of workpieces in the designated position and press the position switch. The equipment automatically measures and records the data to form a database, and the detection data is stored in the background for easy monitoring and analysis of the processing capacity data.

[0024] The working principle of this utility model is as follows:

[0025] In use, the worker first places the trolley filled with material in the loading area. After the trolley is in place, the sensor detects the positioning signal and sends an energizing signal to the electromagnet to position the trolley. After the trolley is positioned, the worker presses the confirmation button, and the system sends a positioning signal to the robot. The robot automatically grabs the workpiece between the first product fixture 10 and the second product fixture 11, and then clamps and positions the product. Subsequently, through the design of the positioning and leveling mechanism 5 and the angle sensor 9, the phase angle of the two tooth surfaces can be measured. After the phase angle measurement is completed, qualified parts are automatically grabbed by the robot and placed into the processing equipment for processing and production, while unqualified parts are automatically transferred to the NG material channel 4.
