Description

Technical Field

[0001] The utility model relates to the technical field of machine tool spindle boxes, in particular to a ram type machine tool spindle box with an inclined gasket for adjusting the distance of rolling guide rails. Background Art

[0002] The ram type machine tool spindle box is an important part of the machine tool. It is usually used to carry and drive the tool for processing. In the ram type machine tool, the spindle box is not only responsible for providing power, but also for adjusting the movement speed and direction of the tool to ensure the processing accuracy. The ram type machine tool spindle box is widely used in various precision processing fields, such as aerospace, mold manufacturing, and automobile manufacturing. They are able to handle complex processing tasks, especially when processing hard-to-process materials such as carbide and high-temperature alloys.

[0003] Common ram-type machine tool spindle boxes are connected by plug-in cooperation between guide rails and sliders, but this method makes it inconvenient to adjust the distance between the ram and the saddle and cannot be accurately assembled. The distance between the ram and the saddle may cause vibration during the processing, thereby affecting the processing accuracy. If this distance is too large, the ram may not be able to remain stable when moving, resulting in increased processing errors. At the same time, since the distance between the ram and the saddle is not convenient to adjust, metal fragments or chips will accumulate between the two during processing, which will accelerate wear and shorten the service life of the machine tool. It cannot meet the working requirements of the ram-type machine tool spindle box. For this reason, a ram-type machine tool spindle box with an inclined gasket to adjust the rolling guide rail distance is proposed. Utility Model Content

[0033] See also Figures 1 to 11 A ram 2 is inserted inside the slide saddle 1, and a cylinder seat 3 is installed on both sides of the top of the slide saddle 1. A balance cylinder 4 is installed on the outer end of the cylinder seat 3, and a universal joint 5 is installed on the outer end of the balance cylinder 4;

[0034] A support seat 6 is installed at the middle position of the top of the slide saddle 1. A reducer 7 is installed on the top of the support seat 6. A feed motor 8 is installed at the outer end of the reducer 7.

[0035] The pressing block 9 is installed on the left and right sides of the front part of the saddle 1. A first fixing block 10 is installed on the inner side of the left pressing block 9. A first oblique pad 11 is installed on the bottom of the first fixing block 10. Second fixing blocks 12 are installed at the four corners of the bottom of the inner cavity of the saddle 1.

Then, by adjusting the insertion depth of the first inclined pad 11, the first inclined pad 11 and the second guide rail slider 20 can be fully fitted, thereby eliminating the distance between the second rolling guide rail 18, so that the fitting clearance can be effectively eliminated to ensure that the ram 2 moves smoothly, has the best running straightness and accuracy, is easy to assemble, and saves time and effort, and can greatly reduce the assembly and inspection costs. After eliminating the fitting clearance, the vibration between the ram 2 and the saddle 1 during processing can be reduced, the processing accuracy is improved, the ram 2 can remain stable during movement, and the processing error is reduced. At the same time, since the distance between the ram 2 and the saddle 1 is adjustable, metal fragments or chips caused by processing will not accumulate between the two, which slows down wear and increases the service life of the machine tool.
