Description

Technical Field

[0001] This utility model relates to the field of tool disc accessories technology, to a tool disc connecting bracket, and particularly to a tool disc connecting bracket with good structural stability and convenient installation and replacement operation. Background Technology

[0002] A cutter head connector is an adapter installed on equipment, connecting to the cutter or saw, and serving to transmit kinetic energy and securely fix it in place. The cutter head connector also functions to reduce noise, absorb vibration, and prevent loosening. A typical cutter head connector structure includes a main body for mounting the cutter head, which is usually fixed to the installation position via threaded connections or bolts. While direct threaded connections are convenient, the rotating cutter makes the connector prone to loosening, which not only generates noise but also risks damaging the equipment. Bolting the cutter head connector to the installation position is more cumbersome for installation and replacement, and prolonged operation (with the cutter rotating) can also cause the cutter to loosen.

[0003] Therefore, developing a cutter head connection bracket with good structural stability and convenient installation and replacement is of great practical significance. Utility Model Content

[0004] Due to the aforementioned defects in the existing technology, this utility model provides a cutter head connecting bracket with good structural stability and convenient installation and replacement operation, so as to solve the problems of cumbersome installation and replacement operation, easy loosening after long-term operation, and short service life of the existing cutter head connecting bracket.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cutter head connecting bracket includes a cutter head mounting post and a bracket fixing seat;

[0007] The cutter head mounting post is a tubular structure and is perpendicularly connected to the bracket fixing seat. The cutter head mounting post is equipped with a cutter head mounting edge assembly for mounting the cutter head. The bracket fixing seat has at least two bracket mounting countersunk holes that penetrate the bracket fixing seat (to avoid exposed bolts, reduce the risk of accidental bolt contact, and improve the overall aesthetics). The bracket fixing seat has an outward protrusion of the fixing seat connecting surface and an inner groove of the fixing seat connecting surface on the side away from the cutter head mounting post.

[0008] This utility model's cutter head connecting bracket has a reasonable structural design. The protruding post on the connecting surface of the fixed seat and the inner groove on the connecting surface of the fixed seat can cooperate with the pre-reserved concave-convex structure on the bracket mounting ring, achieving rapid alignment between the cutter head connecting bracket and the bracket mounting ring, which greatly improves the installation efficiency of the cutter head connecting bracket. At the same time, the protruding post on the connecting surface of the fixed seat acts like a positioning pin, cooperating with the bolts installed at the countersunk holes of the bracket mounting, which greatly increases the rotational stability of the cutter head in the longitudinal direction, reduces vibration during cutter head use, effectively improves product stability, and effectively extends product lifespan, making it highly promising for application.

[0009] As a preferred technical solution:

[0010] As described above, in a cutter head connecting bracket, the cutter head mounting edge assembly includes two annular cutter head mounting edges arranged at parallel intervals.

[0011] The mounting surfaces of the two annular cutter heads are inclined, and the mounting surfaces of the two annular cutter heads form a V-shape.

[0012] As described above, in a cutter head connecting bracket, the bracket fixing seat is a circular ring structure; and the cutter head mounting column is a circular tubular structure.

[0013] As described above, in a cutter head connecting bracket, the hollow structure after the cutter head mounting column is connected to the bracket fixing seat is integrated.

[0014] As described above, the cutter head connecting bracket has two countersunk holes, which are located on both sides of the bracket fixing seat.

[0015] As described above, in a cutter head connecting bracket, there are two protruding columns on the connecting surface of the fixing seat, and the two protruding columns are located on both sides of the bracket fixing seat. The straight line connecting the two protruding columns is perpendicular to the straight line connecting the two countersunk holes of the bracket.

[0016] There are two grooves in the connecting surface of the fixed seat, and the two grooves are located on both sides of the bracket fixed seat. The grooves are located between the protruding post of the connecting surface of the fixed seat and the countersunk hole of the bracket, and divide the space between the countersunk hole of the bracket and the protruding post of the connecting surface of the fixed seat equally.

[0017] As described above, a cutter head connecting bracket is mounted on a bracket mounting ring. The bracket mounting ring has a screw hole that matches the countersunk hole of the bracket mounting ring, a bracket mounting ring groove that matches the outer protrusion of the connecting surface of the fixed seat, and a bracket mounting ring protrusion that matches the inner groove of the connecting surface of the fixed seat.

[0018] After the bolt passes through the countersunk hole of the bracket, it is threaded into the screw hole on the bracket mounting ring, thus using the bolt to fix the cutter head connecting bracket to the bracket mounting ring.

[0019] The outer protrusion of the fixed seat connecting surface mates with the groove of the bracket mounting ring, and the inner groove of the fixed seat connecting surface mates with the protrusion of the bracket mounting ring, which enables quick alignment of the cutter head connecting bracket and the bracket mounting ring. This greatly improves the installation efficiency of the cutter head connecting bracket. The outer protrusion of the fixed seat connecting surface mates with the groove of the bracket mounting ring, and the inner groove of the fixed seat connecting surface mates with the protrusion of the bracket mounting ring, which can act like a positioning pin. In the longitudinal direction, it greatly increases the rotational stability of the cutter head, reduces the vibration generated during the use of the cutter head, effectively improves the stability of the product, and effectively extends the service life of the product.

[0020] As described above, in a cutter head connecting bracket, the outer protruding post of the fixing seat connecting surface is a cylindrical structure; the inner groove of the fixing seat connecting surface is a circular groove.

[0021] The above technical solution is only one feasible technical solution of this utility model. The protection scope of this utility model is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0022] Compared with the prior art, the above-mentioned utility model has the following advantages or beneficial effects:

[0023] (1) The cutter head connecting bracket of this utility model has a reasonable structural design. It can cooperate with the concave and convex structure reserved on the bracket mounting ring by using the protruding column on the connecting surface of the fixed seat and the groove on the connecting surface of the fixed seat to achieve quick alignment between the cutter head connecting bracket and the bracket mounting ring, which can greatly improve the installation efficiency of the cutter head connecting bracket.

[0024] (2) The tool disc connecting bracket of this utility model has a protruding column on the connecting surface of the fixed seat that can play a role similar to a positioning pin. It cooperates with the bolt installed at the countersunk hole of the bracket, which greatly increases the rotational stability of the tool disc in the longitudinal direction, reduces the vibration generated during the use of the tool disc, effectively improves the stability of the product, and effectively improves the service life of the product. It has great application prospects. Attached Figure Description
