[0002] A centerless grinder is a type of grinder that does not require the axis of the workpiece to be positioned for grinding. It is mainly composed of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece holder. The grinding wheel is actually responsible for grinding, the adjusting wheel controls the rotation of the workpiece and the feed speed of the workpiece, and the workpiece holder supports the workpiece during grinding. These three parts can be coordinated in several ways, but the principles are the same except for stopping grinding.

[0003] The existing centerless grinders require manual adjustment of the distance between the grinding wheel and the guide wheel during the grinding process of the workpiece. After the adjustment is completed, the workpiece can be ground. The structure is complex and requires skilled workers to operate. Some construction workers are not skilled enough, resulting in errors and mechanical damage, making it inconvenient to position and lift the workpiece, reducing the speed and efficiency of the device grinding, and bringing inconvenience to the user's work. Therefore, we need to upgrade and transform based on the existing technology. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 - Figure 5 As shown, a centerless grinder for automatically aligning the size of a workpiece provided in this embodiment includes a device body 1, the device body 1 includes a bed 2, a grinding wheel frame 4, a guide wheel frame 7 and a placement table 9 are installed on the bed 2 in sequence, a grinding wheel dresser 5 is installed in the grinding wheel frame 4, a feed handwheel 3 is installed at one end of the grinding wheel dresser 5, a grinding wheel head 8 is installed below the feed handwheel 3, a guide wheel dresser 6 is installed in the guide wheel frame 7, a mounting plate 11 is installed above the placement table 9, a support arm 12 and a support frame 20 are arranged above the mounting plate 11, a card slot 15 is opened on the inner side wall of the support arm 12, a double-pointed splint 16 is installed in the card slot 15, a card plate 18 is clamped above the double-pointed splint 16, a movable slot 21 is opened in the support frame 20, a fixed plate 22 is installed in the movable slot 21, an electric push rod 24 is arranged in the fixed plate 22, and a positioning plate 25 is connected to the upper end of the electric push rod 24.

[0026] Preferably, an electric turntable 10 is installed above the placement table 9, and the upper end of the electric turntable 10 is connected to the mounting plate 11. By setting the electric turntable 10, the device can be rotated and adjusted, which increases the connectivity and intimacy between the devices and provides convenience for users. The support arm 12 is symmetrically arranged at both ends, and a connecting column 13 is fixedly arranged on the outer wall of the support arm 12. A spring 14 is fixedly sleeved on the connecting column 13. By setting the spring 14, the support arm 12 can be buffered when in use, thereby preventing the support arm 12 from breaking due to a large force during the placement of the workpiece 28.

[0027] Preferably, the support arm 12 and the card plate 18 are provided with screw holes 17, and the screw holes 17 are screwed with bolts 19, which can fix and limit the card plate 18, ensure the safety of the card plate 18 when in use, and prevent the card plate 18 from falling off when in use. The upper and lower ends of the double-pointed splint 16 are provided with snap-in grooves, and the double-pointed splint 16 is movably snap-fitted with the card plate 18 and the snap-in groove 15, which can fix and limit the double-pointed splint 16, ensure the safety of the double-pointed splint 16 when in use, and prevent it from falling off. In the event of falling, a slide bar 23 is installed on the upper end of the fixed plate 22, and a slide groove 26 is opened in the positioning plate 25. The slide bar 23 is slidably installed in the slide groove 26, which can guide the moving direction of the fixed plate 22 to avoid the position displacement of the fixed plate 22 during the movement. A clamping groove 27 is opened inside the upper end of the positioning plate 25, and a workpiece 28 is placed in the clamping groove 27. The workpiece 28 is movably connected to the clamping groove 27, which can position and clamp the workpiece 28 to avoid the workpiece 28 falling off.
