Description

Technical Field

[0001] The utility model relates to a measuring device in the field of machining, and particularly relates to a pressing mechanism for a disk-tooth copper sleeve. Background Art

[0002] A copper sleeve needs to be pressed into the central hole of a disk-tooth sleeve. In the prior art, a suitable pressing head is usually equipped on a press to press the copper sleeve into the central hole of the disk-tooth sleeve. Usually, the disk-tooth sleeve is positioned on a fixture, and then the copper sleeve is aligned and pressed in. However, since the copper sleeve and the central hole are in a tightly fitting state with smooth surfaces, and the edge of the copper sleeve itself is also relatively smooth, the copper sleeve is likely to slip during the pressing process, resulting in an inclined pressing situation. This often leads to improper installation of the part and low quality, and even the part is unqualified for installation and directly scrapped. Summary of the Utility Model

[0003] The utility model aims to provide a pressing mechanism for a disk-tooth copper sleeve that can improve the assembly quality of the copper sleeve and the disk-tooth sleeve.

[0004] A pressing mechanism for a disk-tooth copper sleeve in this solution includes a press and a pressing fixture. A pressing head is provided on the press. The pressing fixture includes a base, a guide body, a guide post, and a compression spring. The guide body is vertically fixed on the base. The guide post is slidably arranged in the inner cavity of the guide body. The top of the guide body is open, and the top of the guide post can extend out of the opening. The compression spring is also arranged in the guide body and abuts against the bottom of the guide post. A guide hole is opened at the top of the guide post, and a guide block is provided on the pressing head. The guide block is adapted to the guide hole.

[0005] The central hole of the disk-tooth sleeve is sleeved on the guide post exposed outside the guide body. The port of the central hole of the disk-tooth sleeve is stuck on the guide body. The copper sleeve is placed above the central hole. When the press works, the pressing head presses down. The guide block of the pressing head enters the guide hole, so that the pressing head moves along the direction of the guide hole. After the pressing head clamps the copper sleeve, it is smoothly pressed into the central hole of the disk-tooth sleeve.

[0006] Further, the guide body includes a first guide body and a second guide body. The bottom of the first guide body is fixed on the base, and an internal thread groove is provided at its top. The bottom of the second guide body is provided with an external thread post, and a concave platform is provided at the opening of its top. A clamping platform is arranged in the inner cavity of the second guide body, and a corresponding protrusion is provided on the bottom column of the guide post. The first guide body and the second guide body are threadedly connected through the internal thread groove and the external thread post. The guide body is made into a split structure of the first guide body and the second guide body, which is convenient for the installation of the guide post and the compression spring in the cavity. The guide post slides upward in the inner cavity of the second guide body and is stuck by the clamping platform, playing a limiting role.

[0007] Further, a stop nut is provided at the bottom of the first guide body, the bottom end of the compression spring abuts against the stop nut, and the top end abuts against the bottom of the guide post. The stop nut is used to seal the bottom of the cavity of the first guide body, which facilitates the disassembly of the compression spring in the cavity.

[0008] Further, a through hole is provided in the middle of the base. The stop nut includes a nut head and a nut body. One end of the nut body is provided with the nut head, and the other end is provided with a compression spring groove. The outer wall of the compression spring groove is provided with an external thread, and the side wall of the nut body is closely fitted with the inner wall of the through hole of the base. The compression spring groove is used to place and limit the bottom of the compression spring, and the close fit between the nut body and the base is convenient for fixing, making the structure of the guide body more stable.

[0009] Further, the pressure head includes a pressure head body and a pressure head post. An installation hole is provided on the pressure head body; one end of the pressure head post is the pressure head body, and the other end is the guide block. A pressure platform is provided at the connection between the pressure head post and the pressure head body. The installation hole is used to install it on the press, the pressure head post is used for radial positioning of the copper sleeve, the pressure platform is used for axial positioning of the copper sleeve, and the guide block plays a guiding role.

[0010] Further, the pressure head body, the pressure head post and the guide block are of an integrally formed structure, and the integrally formed structure works more stably.

[0011] The advantages of the present utility model are as follows: Under the action of the guide block and the guide hole, the pressure head can ensure that the working path of its downward pressure does not deviate. Under the limitation of the pressure head, the copper sleeve can be smoothly pressed in. Under the limitation of the press-fitting tooling, the disk tooth sleeve can maintain stability when the copper sleeve is pressed in. Under the collaborative action of the pressure head and the press-fitting tooling, the copper sleeve can be smoothly pressed into the central hole of the disk tooth sleeve, and a high installation quality can be ensured.
