Description

Technical Field

[0001] This utility model belongs to the technical field of mill accessories, specifically relating to a cutter head adapter plate. Background Technology

[0002] Currently, many grinding machine brands have emerged in the floor polishing market. The abrasive block slots of each brand are very different, which means that grinding block construction teams need to select abrasive blocks according to the grinding machine slots, thus limiting the selection of abrasive blocks; or they need to stock up on grinding machines of different brands, increasing equipment investment. In order to solve this problem, this solution was developed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a cutter head adapter plate, which improves the versatility and utilization of the mill by setting an adapter plate that can be adapted to two types of grinding blocks.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cutter head adapter plate, wherein the adapter plate has a plurality of first strip holes arranged in a ring at intervals, the length direction of the first strip holes facing the center of the adapter plate, the adapter plate has a plurality of round holes arranged in a ring at intervals along the center of the adapter plate, the adapter plate has a plurality of second strip holes arranged in a ring at intervals along the center of the adapter plate, the length direction of the second strip holes being arranged along the edge line of the adapter plate, and the first strip holes, round holes and second strip holes are arranged alternately.

[0005] Furthermore, each group has three circular holes arranged in a pyramid shape, and each circular hole has a limiting post on one side, which is also arranged in a pyramid shape.

[0006] Furthermore, the inner wall of the second strip-shaped hole has a limiting ring near the opening, and the limiting ring has an arc-shaped notch in the middle of its length direction.

[0007] Furthermore, there are three first strip holes, three sets of round holes, and three second strip holes.

[0008] Furthermore, the adapter plate has a through hole in the middle, and an annular channel is provided around the opening of the through hole, with a magnet ring provided inside the annular channel.

[0009] Furthermore, an alignment notch is formed on any surface of the adapter plate near the inner circumferential surface.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In this invention, two different grinding block slots exist simultaneously on the same adapter plate: a first strip hole and a round hole, and a second strip hole is a mounting hole for mounting onto the mill. The adapter plate of this solution can switch between two different grinding blocks, which improves the versatility and utilization of the mill and effectively reduces the investment in mill equipment.

[0016] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0017] like Figure 1-3 As shown, this embodiment provides a cutter head adapter plate, which has a first strip hole 1, a round hole 2 and a second strip hole 3, and the first strip hole 1, the round hole 2 and the second strip hole 3 are arranged at intervals.

[0018] The adapter plate has three annularly spaced first strip holes 1. The length direction of the first strip holes 1 is towards the center of the adapter plate, and the width of the first strip holes 1 gradually increases from the outer end to the inner end.

[0019] The adapter plate has three sets of circular holes 2 arranged in a ring around the center of the adapter plate. There are three sets of circular holes 2, with three circular holes 2 in each set. The three circular holes 2 are arranged in a pyramid shape, with two circular holes 2 facing outward and one circular hole 2 facing inward. The circular holes 2 are countersunk holes. Each circular hole 2 has a limit post 21 on one side. The limit post 21 is used for limiting and aligning during mating.

[0020] The adapter plate has three second strip holes 3 arranged in a ring along the center of the plate. The length of the second strip holes 3 is along the edge of the adapter plate. The inner side wall of the second strip hole 3 has a limiting ring 31 near the opening. The limiting ring 31 has an arc-shaped notch 32 in the middle of its length direction for easy locking. The second strip holes 3 are mounting holes for connecting the adapter plate and the mill.

[0021] The adapter plate has a through hole in the middle, and an annular channel is provided around the opening of the through hole. Specifically, one side of the annular channel penetrates the inner circumference of the adapter plate to form an alignment notch. A magnetic ring 4 is provided in the annular channel. The magnetic ring 4 is locked by screws or glue. The magnetic ring 4 provides a magnetic attraction when the adapter plate is installed on the mill, making it easy to tighten the screws without manual dragging.

[0022] In this solution, two different grinding block slots exist on the same adapter plate: the first slot 1 and the round slot 2. The second slot 3 is a mounting hole for mounting onto the mill. The adapter plate of this solution can switch between the two different slots of grinding blocks at will, which improves the versatility and utilization of the mill and effectively reduces the investment in mill equipment.

[0023] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
