Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of equipment detection, and particularly relates to a workpiece detection device. Background Art
[0002] Equipment in modern production is often assembled from multiple components. In order to improve product quality, components are uniformly detected during the process of leaving the factory. To ensure effective assembly in the assembly section, it is necessary to detect and control the position accuracy of multiple holes on the product, so as to avoid defective workpieces flowing into the market and causing problems such as inability to assemble smoothly and difficulty in repair and replacement during the use of workpieces.
[0003] The existing product detection process is mostly completed manually. Traditional workpiece detection uses an offline detection method. First, the workpiece needs to be taken off the production line, manually detected, and then put back on the production line. And a cylinder is directly used to drive the thimble for detection, so as to detect whether each hole is drilled through one by one with the thimble, and judge indirectly through the magnetic opening signal of the cylinder. This method not only has low efficiency, low accuracy, affects the production rhythm, poor stability, but also has more misdetection situations.
[0004] In view of the above situation, it is urgent to design a detection device to solve the problems of low efficiency and poor accuracy of offline detection. Realize fast online detection of workpieces and improve the detection accuracy. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a workpiece detection device to solve the problems of low detection accuracy and low efficiency mentioned in the above background art. The following technical solutions are provided: A workpiece detection device, comprising:
[0006] A bracket, on one side of the bracket is provided a conveyor line, at one end of the conveyor line is provided a lifting assembly for lifting the workpiece to be detected, and a workpiece stop block is further provided on one side of the lifting assembly;
[0007] A sliding group is arranged at the upper end of the bracket, and a clamping group is arranged at one end of the sliding group, and the clamping group is used for transporting the workpiece;
[0008] A detection mechanism is arranged below the clamping group, and the detection mechanism is used for detecting the workpiece.
[0009] In this technical solution, the working steps of the device are as follows: First, the workpiece is stopped by the stop block on the conveyor line, and the lifting mechanism lifts the workpiece. Second, the clamping group grabs the workpiece to the upper end of the detection mechanism through a pneumatic gripper. Third, the detection mechanism rises to detect whether all four hole positions in the workpiece are through holes. Fourth, after the judgment is completed, the detection mechanism returns to its original position, the workpiece is reset through the sliding group and the clamping group, the lifting mechanism descends, the blocking block releases, and the workpiece flows to the next station.
[0010] In any of the above technical solutions, further, the sliding group is fixedly arranged on one side of the bracket. The sliding group is provided with a slider, and the slider is pushed by a first air cylinder fixed on the other side of the bracket. The clamping group includes a second air cylinder, which is fixedly arranged below the slider. A pneumatic gripper is arranged at the lower end of the second air cylinder, and the pneumatic gripper is used for clamping the workpiece to be detected. A workpiece fixing plate is also arranged directly below the pneumatic gripper, and the workpiece fixing plate is horizontally and fixedly arranged on the bracket.
[0011] In this technical solution, both the sliding group and the clamping group adopt pneumatic transmission. Pneumatic transmission has advantages such as fast response and low cost. Moreover, when the workpiece fixing plate transports the workpiece from the bracket to the upper end of the detection mechanism, the workpiece is clamped on the workpiece fixing plate, thus ensuring the accuracy and stability of the next detection.
[0012] In any of the above technical solutions, further, the detection mechanism includes a detection air cylinder, which is fixedly arranged at the lower end face of the workpiece fixing plate. A second fixing plate is fixedly arranged at the lower end of the detection air cylinder. Limiting cylinders are evenly arranged at the four corners of the second fixing plate. A sliding rod is slidably arranged in the middle of the second fixing plate, and a spring is arranged between the sliding rod and the second fixing plate. There are four sliding rods, and a thimble is fixedly arranged at the upper end of the sliding rod. The upper end of the thimble passes through the upper end of the workpiece fixing plate.
[0013] The lower end of the sliding rod passes through one side of the second fixing plate, and the lower ends of two adjacent sliding rods are connected with a connecting piece. A small hole is arranged in the middle of the connecting piece. A photoelectric sensor is also arranged at the lower end face of the second fixing plate, and the photoelectric sensor is flush with the middle position of the two connecting pieces.
[0014] In this technical solution, through the vertically arranged sliding rods, with thimbles arranged at the upper ends of the sliding rods and connecting pieces arranged at the lower ends, and a small hole is opened in the middle of the connecting piece. When the thimble passes through the detection hole in the workpiece, the spring force keeps the sliding rod and the thimble in place. At this time, the small holes in the middle of the two lower connecting pieces are flush. At this time, the light source emitted by the photoelectric sensor can pass horizontally, so as to further distinguish the rising distance of each thimble by whether the light can pass through, and quickly detect the through holes opened in the workpiece.
[0015] The detection air cylinder drives the second fixing plate to rise, and the four thimbles also rise together to detect whether the four hole positions are all through holes. If they are all through holes, the holes in the middle of the two connecting pieces are at the same level, and the photoelectric transmissive sensor is in the "ON" state; if one of them is not a through hole, the holes in the middle of the two connecting pieces are not at the same level, and the photoelectric transmissive sensor is in the "OFF" state.
[0016] In this device, the detection of the small hole position of the connecting piece by the sensor is used to indirectly realize the detection of the vertical through holes in the workpiece, reducing the difficulty coefficient of sensor detection and increasing the detection accuracy.
[0017] The beneficial effects of the present utility model are as follows: Through the slide bar arranged in the vertical direction, and a thimble is arranged on the slide bar. The detection cylinder drives the second fixed plate to rise, and the four thimbles also rise together to detect whether all four holes are through holes. If they are all through holes, the middle holes of the two connecting pieces are at the same horizontal level, and the photoelectric transmissive sensor is in the "ON" state; if one of them is not a through hole, the middle holes of the two connecting pieces are not at the same horizontal level, and the photoelectric transmissive sensor is in the "OFF" state. The detection of the vertical through holes in the workpiece is realized by the on-off of the photoelectric transmissive sensor during detection, which reduces the difficulty coefficient of sensor detection and increases the detection accuracy.
