Abstract
Description
Technical Field
[0001] This utility model relates to the field of machine tool gearbox technology, and in particular to a machine tool gearbox housing. Background Technology
[0002] Most CNC machine tool spindles are equipped with shiftable gearboxes. As an important component of CNC machine tool equipment, the spindle gearbox plays a role in transmitting power. It expands the versatility of the machine tool by switching between high and low speeds through the shifting mechanism. It can perform high-speed light cutting to process flexible materials in high-speed gears, and can also meet the needs of low-speed heavy cutting (high cutting force) to process hard materials in low-speed gears.
[0003] Traditional gearbox housings are generally composed of a cover and a body, which have high processing requirements and are difficult to process. Typically, the cover and body need to be rough-machined independently first, and then the cover and body are connected together with bolts and tapered pins and then machined to the corresponding dimensions at the same time. In addition, there is only one way to connect the gearbox to the main shaft box, which is to fix the gearbox to the main shaft box with bolts, resulting in poor compatibility. Utility Model Content
[0004] The purpose of this utility model is to provide a machine tool gearbox housing to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A machine tool gearbox housing includes an integrally formed shell. Each of the corresponding side walls of the shell has a boss with a first mounting hole. The top of the shell has a motor connection platform with an input end inside. The bottom of the shell has an output end. The bottom surface of the shell around the output end has several second mounting holes. One side wall of the shell adjacent to the side walls containing the bosses has a first assembly window. Both side walls containing the bosses have second assembly windows. The first and second assembly windows communicate with the inner cavity of the shell.
[0006] Preferably, the machine tool gearbox housing further includes a transition plate, the transition plate having a through groove, a plurality of third mounting holes at the outer periphery of the through groove, and a plurality of fourth mounting holes at the edge of the transition plate. The transition plate is mounted to the bottom of the housing by bolts connecting the third mounting holes and the second mounting holes. The output end is located in the through groove and passes through the through groove. The transition plate is mounted to the top of the spindle box by bolts and the fourth mounting holes.
[0007] Preferably, the boss is positioned close to the side wall where the first assembly window is located, and the second assembly window is positioned away from the side wall where the first assembly window is located. The boss and the first assembly window are adjacent to each other on the same side wall of the housing.
[0008] Preferably, the dimensions of the second assembly windows on both sides are larger than those of the first assembly windows.
[0009] Preferably, both the first and second assembly windows are provided with sealing ring grooves and screw holes.
[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model simplifies the machining process and improves machining efficiency by using a one-piece molded gearbox housing, allowing for one-time clamping and machining. Two different installation methods can be achieved by using a boss and a transition plate: one method involves directly mounting the gearbox to the top of the headstock via the transition plate; the other involves inserting the gearbox portion into the headstock and fixing it to the side of the headstock via the boss. These two connection methods can be flexibly adjusted and selected according to requirements and actual conditions, improving the gearbox's adaptability. Attached Figure Description

Detailed Implementation
[0013] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.
[0014] Example 1 like Figure 1-6 As shown, a machine tool gearbox housing includes an integrally formed shell 1. Bosses 2 are provided on corresponding side walls of the shell 1. First mounting holes 3 are provided on the bosses 2. A motor connection platform 4 is provided at the top of the shell 1, with an input end 5 inside the motor connection platform 4. An output end 6 is provided at the bottom of the shell 1. Several second mounting holes 9 are provided on the bottom surface of the shell 1 surrounding the output end 6. A first mounting window 7 is provided on one side wall of the shell 1 adjacent to the side walls where the two bosses 2 are located. Second mounting windows 8 are provided on both side walls of the shell 1 where the two bosses 2 are located. The bosses 2 are positioned closer to the side wall where the first mounting window 7 is located, and the second mounting windows 8 are positioned away from the side wall where the first mounting window 7 is located. The bosses 2 and the first mounting windows 7 are adjacent to each other on the same side wall of the shell 1.
[0015] The first assembly window 7 and the second assembly window 8 are connected to the inner cavity of the housing 1. The dimensions of the second assembly windows 8 on both sides are larger than those of the first assembly window 7.

[0016] The drive motor 10 is mounted on the motor connecting platform 4 by bolts. The motor output shaft is connected to the input end 5 for transmission. The transmission gear is inserted into the housing 1 through the first assembly window 7 and the second assembly window 8 for assembly. After assembly, the plexiglass is sealed on the first assembly window 7 and the second assembly window 8 by sealing rings and screws to prevent the lubricating oil inside the gearbox from overflowing. The gear structure inside the gearbox is existing technology and will not be described in detail here.
[0017] The machine tool gearbox housing also includes a transition plate 11. A through groove 12 is provided on the transition plate 11.
