Floating type pressure plate structure

Abstract

The utility model relates to a floating type pressure plate structure, which consists of a feeding table, a feeding plate, a pressure column seat, a fixing bolt, a floating sleeve, a floating shaft, a spring, a pressure plate bearing seat, a cylindrical pin and a bearing, and is characterized in that when a thin workpiece feeding plate is used, the edge of the feeding plate is easy to warp and deform, the floating shaft floats upwards, and the spring on the surface of the floating shaft shrinks upwards, so that the thin workpiece feeding plate is fixed. When the feeding disc rotates, a downward force is generated, so that the feeding disc is prevented from buckling deformation, when the feeding disc rotates, a bearing for pressing the feeding disc also rotates, the friction loss of the feeding disc is reduced, the structural design is simple and reasonable, the service life of the feeding disc is prolonged, the grinding deformation of the feeding disc is avoided, and meanwhile, the stability of workpiece machining is also improved.

Description

Technical Field

[0001] The utility model relates to the field of pressing a thin workpiece feeding plate, in particular to a floating pressing plate structure. Background Art

[0002] At present, when a double-end surface grinder is grinding a thin workpiece, the thickness of the feed plate used is also very thin. Because the working environment of the feed plate is very complex and the feed plate is very thin, the edge of the feed plate is easily warped and deformed. After the feed plate is deformed, not only the service life of the feed plate is reduced, but also the processing accuracy of the workpiece is affected. Therefore, it is necessary to design a clamping structure that can not only ensure the processing quality of the workpiece, but also effectively improve the service life of the feed plate. Summary of the invention

[0003] The technical solution adopted by the utility model to solve the above-mentioned problems is: a floating pressure plate structure, which is composed of a feeding platform, a feeding plate, a pressure column seat, fixing bolts, a floating sleeve, a floating shaft, a spring, a pressure plate bearing seat, a cylindrical pin, and a bearing, and is characterized in that: the feeding platform is placed horizontally, a feeding plate is installed on the feeding platform, and the feeding plate is kept horizontal after installation, evenly distributed pressure column seats are installed on the edge of the feeding platform, a floating sleeve is installed on the pressure column seat, the floating sleeve and the pressure column seat are connected and fixed by fixing bolts, a floating shaft is installed in the circular hole of the floating sleeve, a pressure plate bearing seat is installed at the thread at the bottom of the floating shaft, a spring is installed between the floating sleeve and the pressure plate bearing seat, and the spring is wrapped around the outer surface of the floating shaft, a bearing is installed at the groove at the bottom of the pressure plate bearing seat, and the bottom of the bearing is in close contact with the feeding plate, and the cylindrical pins are installed in the circular holes on both sides of the groove of the pressure plate bearing seat to fix the bearing.

[0004] The utility model adopts the above structure and the floating pressure plate structure, which not only increases the service life of the feeding plate, but also avoids the grinding deformation of the feeding plate, and also improves the stability of workpiece processing.

[0008] The utility model is further described below in conjunction with the accompanying drawings:

[0009] like Figure 1, Figure 2 As shown, the utility model relates to a floating pressure plate structure, which consists of a feeding platform 1, a feeding plate 2, a pressure column seat 3, a fixing bolt 4, a floating sleeve 5, a floating shaft 6, a spring 7, a pressure plate bearing seat 8, a cylindrical pin 9, and a bearing 10. It is characterized in that: the feeding platform 1 is placed horizontally, the feeding plate 2 is installed on the feeding platform 1, and the feeding plate 2 is ensured to be horizontal after installation, and evenly distributed pressure column seats 3 are installed on the edge of the feeding platform 1, and a floating sleeve 5 is installed on the pressure column seat 3, and the floating sleeve 5 and the pressure column seat 3 is connected and fixed by fixing bolts 4, a floating shaft 6 is installed in the round hole of the floating sleeve 5, a pressure plate bearing seat 8 is installed at the thread at the bottom of the floating shaft 6, a spring 7 is installed between the floating sleeve 5 and the pressure plate bearing seat 8, and the spring 7 is wrapped around the outer surface of the floating shaft 6, a bearing 10 is installed at the groove at the bottom of the pressure plate bearing seat 8, and the bottom of the bearing 10 is in close contact with the feed tray 2, and the cylindrical pin 9 is installed in the round holes on both sides of the groove of the pressure plate bearing seat 8 to fix the bearing 10.

[0010] When the utility model is in use, the feed tray 2 is first installed horizontally on the feed platform 1, and the height of the floating shaft 6 is adjusted to make the bearing 10 in close contact with the feed tray 2. When the feed tray 2 starts to rotate to feed, the bearing 10 in close contact with the feed tray 2 also rotates with the rotation of the feed tray 2, thereby forming a relative motion to reduce the friction loss of the feed tray 2. When the edge of the feed tray 2 begins to warp and deform, the pressure plate bearing seat 8 will drive the floating shaft 6 to move upward, and the spring 7 on the surface of the floating shaft 6 will also shrink upward. The contraction of the spring 7 will generate a downward force, and this force will make the deformation of the feed tray 2 disappear.

[0011] The utility model adopts the above structure and the floating pressure plate structure, which not only increases the service life of the feeding plate, but also avoids the grinding deformation of the feeding plate, and also improves the stability of workpiece processing.
