Description

Technical Field

[0001] The utility model is applicable to the field of road construction material production equipment and provides a suspended swing type curbstone rounded corner fine grinding device. Background Art

[0002] A curbstone is a road marking stone used to mark the boundaries of roads. It is often used to isolate different roads. In order to highlight the boundary function, curbstones are generally installed and laid with part of the road surface exposed. In actual production, the edges of the curbstones exposed to the ground are usually rounded. The rounded edges are not only more beautiful, but also will not cause accidents due to overly sharp edges. In our company's past production plans, arc-shaped cutters are usually used to cut the right-angled edges of curbstones longitudinally to make them rounded. However, the rounded surface produced by this direct pull-cutting method is too rough, and longitudinal cuts will appear, affecting the appearance. At the same time, the longitudinal cutting method will cause the cutter to be subjected to greater force, and it is more likely to be damaged after long-term use. Summary of the invention

[0003] To this end, the utility model provides a suspended swinging curb stone rounded corner fine grinding device, which uses an angle grinder unit to grind the edge of the curb stone base. By fixing multiple angle grinder units on the same grinder fixing plate, the fixed plate driving device drives the grinder fixing plate to swing in an arc through the swing unit, so that the grinder fixing plate can drive the angle grinder unit to grind the edge of the curb stone base in an arc direction.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a suspended swing type curbstone rounded corner fine grinding device, comprising:

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] For example, see the attached Figure 1 The utility model provides a suspended swing type curbstone rounded corner fine grinding device, comprising a curbstone conveyor line 1 for transporting a curbstone substrate 6 to be processed. The curbstone conveyor line 1 adopts a conventional assembly line conveyor belt form, which can be stopped or run according to the working conditions. In this way, when the curbstone substrate 6 reaches the processing position, the curbstone conveyor line 1 will temporarily stop and continue to run after the processing is completed. A rounded corner fine grinding module 3 is arranged above the curbstone conveyor line 1, as shown in the attached Figure 2 As shown, the fillet fine grinding module 3 includes a support frame 31, and the support frame 31 is provided with a curbstone positioning contact block 37 facing the curbstone conveying line 1. The curbstone positioning contact block 37 is used to locate the curbstone processing position. At the same time, the support frame 31 is rotatably provided with a grinder fixing plate 32, and the support frame 31 is fixedly provided with a fixing plate driving device 35. The fixing plate driving device 35 is connected to the grinder fixing plate 32 through a swing unit driving connection. The fixing plate driving device 35 is a reduction motor. The swing unit includes a rotating driving plate 33 and a swing connecting rod 34. The grinder fixing plate 32 is provided with a plurality of angle grinder units 36, as shown in the attached Figure 3As shown, the angle grinder unit 36 ​​includes an angle grinder linear drive device 361, which is driven by an angle grinder motor 362, which is driven by an angle grinder head 363, which is a felt grinding head. The felt grinding head has a good grinding effect and a smoother grinding surface. The reduction motor drives the rotating drive plate 33 to rotate, and the rotating drive plate 33 drives the swing connecting rod 34. The swing connecting rod 34 finally drives the grinder fixed plate 32 to make a periodic arc swing, so that the grinder fixed plate 32 is fixed. The plate 32 can carry the rounded corner grinding head 363 to round the edge of the curbstone base 6 along the arc direction. The linear drive device 361 of the angle grinder can adopt a linear motor or other device that can accurately control the displacement. After the rounded corner grinding head 363 is worn, the angle grinding motor 362 is moved by the linear drive device 361 of the angle grinder to ensure that the rounded corner grinding head 363 is always in the best working position; the curbstone conveyor line 1 is directly connected to the rounded corner fine grinding module 3 through the lifting device 2, and the lifting device 2 is fixedly arranged on the curbstone conveyor line 1. The lifting device 2 is driven and connected to the support frame 31 to drive the rounded corner fine grinding module 3 to rise and fall. The lifting device 2 includes at least two screw lifts and a lifting drive motor. In this embodiment, a solution of two screw lifts is adopted. The two screw lifts are driven and connected by a synchronous lifting coupling, and one of the screw lifts is driven and connected to the lifting drive motor. Such a structure can ensure the synchronous lifting between multiple screw lifts, increase the lifting stability, and the rounded corner fine grinding module 3 and the curbstone conveyor line 1 are connected. Several limiting guide rods 4 are also provided, which are fixedly connected to the curbstone conveyor line 1 and slidably connected to the support frame 31. The purpose of the limiting guide rods 4 is to improve the lifting stability and avoid deviation after long-term use. A curbstone limiting module 5 is provided on one side of the curbstone conveyor line 1. The curbstone limiting module 5 includes a push plate linear drive device, which is driven by a curbstone correction push plate. The curbstone correction push plate can push the curbstone base 6 on the curbstone conveyor line 1 to the angle grinder unit 36.

[0023] The working principle of this embodiment is as follows:

[0024] First, the rounded corner fine grinding module 3 is adjusted to a suitable height by the lifting device 2, and then the curbstone substrate 6 to be processed begins to be conveyed along the curbstone conveyor line 1. When the curbstone substrate 6 is conveyed to the bottom of the rounded corner fine grinding module 3, the curbstone substrate 6 is pushed to the other side edge and abuts against the curbstone positioning contact block 37 by the curbstone correction push plate of the curbstone limiting module 5. At this time, the fixed plate driving device 35 is started, and the grinder fixed plate 32 begins to drive the rounded corner grinding head 363 of the angle grinder unit 36 ​​to perform reciprocating arc grinding on the edge of the curbstone substrate 6, until the rounded corner processing of the edge of the curbstone substrate 6 is completed and then transferred to the next process through the curbstone conveyor line 1.
