Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts detection, and in particular relates to a workpiece height detection device. Background Art

[0002] In the production process of automobile parts, product quality requires good dimensional stability. Due to technical defects and deficiencies, the dimensional stability of some products is difficult to meet the quality requirements, and even leads to the outflow of defective products due to dimensional deviation. In the production process, the rubber gaskets in the gasketing process are dark in appearance and the gaskets are easy to stick to each other, which is not easy to find when the gaskets are put on manually. Once defective automobile workpieces or unqualified automobile workpieces flow into the assembly line, it will affect the performance and safety of the car. Therefore, in order to avoid the outflow of unqualified automobile workpieces, the usual countermeasures are: add a process of 100% detection of key dimensions by manual measurement tools after processing and before packaging. However, this method of manually using measurement tools to detect automobile workpieces is not only inefficient, but also prone to problems such as missed detection and wrong detection, making it difficult to ensure the quality of automobile workpieces. Utility Model Content

[0003] In summary, in order to overcome the deficiencies of the prior art, the utility model provides a workpiece height detection device.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a workpiece height detection device, comprising a detection mechanism, a feeding mechanism and a material shifting mechanism for controlling the movement of the workpiece, the detection mechanism comprising a detection platform, a first discharging mechanism for conveying a qualified workpiece gauge and a second discharging mechanism for conveying a unqualified workpiece gauge are respectively arranged on both sides of the detection platform, the feeding mechanism is arranged in parallel with the first discharging mechanism, a limited end is arranged at the other end of the feeding mechanism relative to the feed port, a feeding port is arranged at the side of the limited end corresponding to the detection platform, the material shifting mechanism is arranged at the other side of the limited end relative to the feed port, the material shifting mechanism comprises a clamping assembly for pushing the workpiece gauge to move forward and backward and an electric slide rail for driving the clamping assembly to move left and right, the detection mechanism also comprises a mounting frame arranged on the other side of the detection platform relative to the feeding mechanism and a pneumatic displacement sensor for detecting whether the height of the assembled workpiece is within a set range by up and down displacement, the pneumatic displacement sensor is arranged above the detection platform, and a control cabinet for controlling the material shifting mechanism and the pneumatic displacement sensor is arranged next to the mounting frame.

[0005] By adopting the above technical solution, multiple inspection fixtures are arranged on the feeding mechanism, and the inspection fixtures are placed with workpieces to be inspected and height gaskets (taking the workpiece assembled with the height gasket as an example, it can also be used for other assembled workpieces to be inspected by height difference). The clamping component moves the inspection fixture at the limit end forward to the inspection table, and the moving component of the pneumatic displacement sensor moves down to contact the top of the workpiece in the inspection fixture. The sensor compares the displacement distance of the moving component with the set range to determine whether the workpiece is qualified. If qualified, the clamping component clamps the qualified workpiece and connects the inspection fixture to the first discharging mechanism through the electric slide rail. If unqualified, it moves to the second discharging mechanism, and then the clamping component resets and moves backward, and then the electric slide rail drives the clamping mechanism to reset. When the electric slide rail is reset, the feeding mechanism continues to send the next inspection fixture to the limit end and repeats the above steps; automated detection is performed to determine whether the number of height gaskets is accurate, thereby avoiding the human influence caused by manual product recognition fatigue in visual selection, improving selection efficiency and product quality stability, and improving the recognition rate of defective products.

[0006] The utility model is further configured that: the control cabinet comprises a display screen and a control button for setting a setting range of the pneumatic displacement sensor.

[0007] By adopting the above technical solution, the setting range of the dynamic displacement sensor can be adjusted according to different workpieces to be detected, thereby improving the applicability of the detection device, and the detection is made more accurate through visual operation on the display screen.

[0008] The utility model is further configured as follows: a detection station is arranged on the detection table, a proximity switch is arranged at a position of the mounting frame corresponding to the detection station, and a gauge positioning member for positioning a workpiece gauge is arranged above the proximity switch.

[0009] By adopting the above technical solution, the clamping mechanism drives the gauge forward until it abuts against the gauge positioning piece, and determines whether the gauge is in place through the proximity switch, ensuring that the top of the workpiece in the gauge is aligned with the moving component that starts the displacement sensor, thereby improving the accuracy of detection.

[0010] The utility model is further configured as follows: the mounting frame includes an upper and lower adjustment rail and a first mounting platform movably arranged on the upper and lower adjustment rails, the pneumatic displacement sensor is arranged on the first mounting platform, and a first adjustment component for adjusting and positioning the height of the first mounting platform is arranged on one side of the first mounting platform.

[0011] By adopting the above technical solution, it can be used to detect workpieces of different heights, has a wider applicability, is adjusted through the first adjusting component, has a simple structure, and is easy to operate.

[0012] The utility model is further configured as follows: a second mounting platform and a second adjustment component for adjusting and positioning the height of the second mounting platform are also provided on the upper and lower adjustment rails; the second mounting platform is arranged below the first mounting platform; and the inspection fixture positioning member is detachably connected to the second mounting platform.

[0013] By adopting the above technical solution, it can be used to detect workpieces of different specifications. When the workpiece is small, the inspection fixture on which the workpiece is loaded also needs to be replaced. Therefore, the inspection fixture positioning piece can be disassembled and replaced with other shapes, and its height can be adjusted. It is simple to assemble and has wide applicability.

[0014] The utility model is further configured as follows: a mounting base plate, a front and rear adjustment rail and a mounting slide are arranged below the mounting frame, the front and rear adjustment rail is arranged on the mounting base plate, the mounting slide is movably arranged on the front and rear adjustment rail, and a third adjustment component for adjusting and positioning the front and rear position of the mounting slide is arranged on one side of the mounting slide.

[0015] By adopting the above technical solution, the installation slide can be adjusted forward and backward, and the positioning can be performed or released through the third adjustment component. The front and rear adjustment rails and the installation slide are directly connected by sliding with dovetail grooves, making their movement and adjustment more stable.
