Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of boring machine components, specifically to a boring machine spindle head. Background Technology
[0002] The spindle head of a boring machine is one of the key components of its performance. It is directly responsible for driving the boring tool to perform rotary cutting motion and bearing the cutting force. Its performance directly determines the accuracy and processing efficiency of boring.
[0003] Many factors can cause instability during machine tool processing. Therefore, enhancing the rigidity and stability of the spindle head plays a substantial role in improving the accuracy of the machine tool. Utility Model Content
[0004] To address the aforementioned problem of enhancing the rigidity and stability of the spindle head, this invention proposes a boring machine spindle head, comprising a main body, which is square in shape and hollow inside, with internal ribs; the main motor and gearbox of the spindle transmission mechanism are mounted at one end of the main body.
[0005] A further feature of this invention is that two windows for observation and installation are provided on one side surface of the main body.
[0006] A further feature of this invention is that the reinforcing wall is arranged in a grid pattern.
[0007] The beneficial effects of this utility model are as follows:
[0008] By incorporating a ribbed, grid-like ribbed wall within the main body, the stability of the main body is improved, significantly reducing the deformation of the spindle head due to heat and stress. Simultaneously, mounting the main motor at the end of the main body avoids placing the motor inside the spindle head, solving the motor heat dissipation problem, eliminating the need for a water chiller, and reducing costs.

[0016] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0017] This utility model proposes a boring machine spindle head, including a main body 1, wherein the main body 1 adopts HT
[0018] Made of 300 high-strength gray cast iron material and cast using environmentally friendly resin sand process.
[0019] The main body 1 is square and hollow inside, with reinforced walls 2 welded inside to enhance its structural strength. The main shaft transmission mechanism is located inside the main body 1, and includes a main motor and a gearbox. The main motor and gearbox are installed on the outside of one end of the main body 1, which avoids installing them on the inside of the main body 1. This allows for better heat dissipation of the main motor and eliminates the need to install a water chiller for cooling.
[0020] Two windows 11 are also provided on one side surface of the main body 1 for observation and installation, so as to be used for installation and observation during installation.
[0021] The reinforcing wall 2 is arranged in a grid pattern, that is, in a matrix pattern. The matrix-type reinforcing wall 2 is welded inside the main body 1, and the arrangement of the reinforcing wall 2 will not affect the main shaft transmission mechanism.
[0022] It should be noted that the internal structures of the main body 1 are arranged in a symmetrical manner.
[0023] In summary, this invention improves the stability of the main body 1 by setting a ribbed wall 2 inside the main body 1, thereby significantly reducing the deformation of the spindle head due to heat and stress. Simultaneously, installing the main motor at the end of the main body 1 avoids placing the motor inside the spindle head, solving the motor heat dissipation problem, eliminating the need for a water chiller, and reducing costs.
[0024] Although the present invention has been described with reference to preferred embodiments, various modifications can be made to it and components can be replaced with equivalents without departing from the scope of the present invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
