Description

Technical Field

[0001] The utility model relates to the processing of printer parts, in particular to the detection of a roller plate of a large printer. Background Art

[0002] The long flat plate on the large printer is equipped with rollers, which are used to guide the paper so that the paper entering the printer can smoothly exit the printer. There are a number of rollers on the long flat plate, which are distributed along the length of the long flat plate, and the rolling direction of the rollers is perpendicular to the length of the long flat plate. In production, after the rollers are installed, the long flat plate needs to be checked to determine whether the horizontality of the long flat plate is within the allowable error range. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a detection platform for detecting the horizontality of long flat plates.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a printer plate horizontality detection platform, including a frame installed on a workbench, a horizontal guide rail arranged on the frame, and a slide table slidingly matched with the horizontal guide rail. The frame is provided with a product positioning structure, and the slide table is provided with a detection instrument. The detection instrument is located below the product positioning structure. The frame is provided with a driving unit for driving the slide table to linearly displace along the horizontal guide rail. The product positioning structure includes a fixed support table and a movable support table mechanism installed on the frame. The movable support table mechanism includes a screw mechanism and a movable support table. The movable support table is connected to the screw nut of the screw mechanism.

[0005] According to the above technical solution, one end of the long flat plate is placed on a fixed support platform, and the other end is placed on a movable support platform. The driving unit drives the slide to translate along the horizontal guide rail, and the detection instrument moves accordingly to detect the horizontality of the long flat plate above it. The detection result is fed back to the main control unit, and the main control unit displays the result on a display (the display can be placed on a workbench, and the main control unit is located in a chassis and placed on the workbench), and the display represents the detection result in the form of a curve. The reference line of the curve is the ideal horizontal straight line of the long flat plate. As the detection instrument translates along the long flat plate, the curve displayed by the display fluctuates up and down relative to the reference line, and the fluctuation amplitude is within the allowable range, indicating that the horizontality of the long flat plate is qualified, otherwise, it is unqualified. As an option, the detection instrument uses a distance sensor. The ideal horizontality of the long flat plate is that the long flat plate maintains a fixed distance from the translation distance sensor, and the fixed distance is the reference line. In fact, the distance between the long flat plate and the translation distance sensor will fluctuate, and the fluctuation amplitude is within the allowable range, indicating that the horizontality of the long flat plate is qualified.

[0006] Driven by the lead screw mechanism, the movable support table translates, and the distance between it and the fixed support table is adjusted to accommodate long and flat plates of different lengths.

[0007] The frame includes a pair of vertical side plates and a vertical cross plate fixed between the pair of vertical side plates. The horizontal guide rail is fixed on the side wall of the vertical cross plate. The fixed support table is fixed on the top of the vertical cross plate. The movable support table mechanism is located behind and above the vertical cross plate.

[0008] The lead screw of the lead screw mechanism is pivotally connected to the middle vertical plate. The lead screw mechanism motor is installed on the middle vertical plate through a connecting rod. The lead screw mechanism motor is connected to the lead screw. The lead screw nut is embedded in the movable support. The movable support is fitted on a pair of horizontal guide rods. One end of the horizontal guide rod is connected to the middle vertical plate, and the other end is connected to a vertical side plate. The movable support table is installed on the movable support. The lead screw mechanism motor drives the lead screw to rotate. The lead screw drives the movable support to translate along a pair of horizontal guide rods through the lead screw nut, and the movable support table translates with the movable support.

[0009] The movable support is provided with a guide block with a concave cross section. The movable support table is provided with a convex structure. The convex structure cooperates with the concave structure of the guide block. The movable support table is provided with a strip hole, and a long bolt is fitted in the strip hole. The long bolt connects the movable support table and the guide block. The movable support table is provided with a horizontal support surface, and the horizontal support surface is at the same height as the support surface of the fixed support table. In order to make the horizontal support surface of the movable support table at the same height as the support surface of the fixed support table, a level is placed on the horizontal support surface and the support surface of the fixed support table. The long bolt is loosened, and the height of the movable support table is adjusted. When the level is horizontal, the long bolt is tightened to fix the relative position of the movable support table and the movable seat.

[0010] A locking screw is screwed on one side wall of the movable support table. One end of the locking screw can abut against the side wall of the convex structure. A dial is provided on the other side wall of the movable support table. When adjusting the height of the movable support table, the operator uses his left hand to slightly lift and lower the movable support table through the dial. When the level is horizontal, the operator uses his right hand to tighten the locking screw so that one end of the locking screw abuts against the side wall of the convex structure. In this way, the relative position between the movable support table and the movable support is temporarily fixed. Then, the long bolt is tightened to fix the relative position between the movable support table and the movable support.

[0011] The driving unit is a synchronous belt mechanism, which includes a synchronous belt pulley mounted on the frame, a synchronous belt motor connected to one synchronous belt pulley, a synchronous belt engaged with the synchronous belt pulley, a connecting cross plate provided at the bottom of the sliding table, and the synchronous belt is fixedly connected to the connecting cross plate. A pressing plate presses the synchronous belt against the connecting cross plate to achieve the fixed connection between the synchronous belt and the connecting cross plate. The synchronous belt motor is mounted on a vertical side plate through a motor base. The synchronous belt motor drives the synchronous belt pulley, the synchronous belt pulley drives the synchronous belt, and the synchronous belt drives the sliding table, and the sliding table translates under the guidance of the horizontal guide rail.
