Description

Technical Field

[0001] The utility model relates to the technical field of spindle heads, and specifically relates to a new type of spindle head horizontally installed. Background Technique

[0002] During the assembly of existing lathes, due to the self-characteristics of 45-degree lathes, there are problems in the hoisting and assembly of spindle heads, such as difficult fixation and inhumane precision adjustment. The main problem is that the self-weight of the spindle head will slide down on the 45-degree inclined plane, which causes difficulties in assembly.

[0003] However, for smooth chip evacuation and the safety of the folding cover, the bed body has to be made at 45 degrees. The spindle installation surface at the same angle as the linear guide (hard guide) has higher technical requirements during processing, such as flatness, parallelism, and geometric tolerances. Without corresponding technical requirements, the precision problems between the installed spindle and the turret will be infinitely magnified. Therefore, a new type of horizontally installed spindle head is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] The present invention provides a technical solution, a new type of horizontally installed spindle head. Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , including:

[0027] A spindle head 1 and a base 3. The spindle head 1 is arranged at the upper end of the base 3. An adjustment block 2 is arranged at the front side of the upper end of the base 3. Two top through holes 6 are arranged at the upper end of the adjustment block 2;

[0028] An oval hole 4 is arranged at the front end of the left side of the adjustment block 2. A side screw hole 5 is arranged at the front end of the right side of the adjustment block 2;

[0029] A bottom screw hole 9 is arranged inside the upper end of the base 3. A fixing bolt 12 is installed inside the top through hole 6. A pulling-back bolt 10 is arranged inside the oval hole 4. The pulling-back bolt 10 penetrates through the oval hole 4 and extends into the spindle head 1, and the pulling-back bolt 10 is connected with the spindle head 1 through threaded cooperation. A pushing bolt 11 is installed inside the side screw hole 5;

[0030] A gasket 13 is arranged between the spindle head 1 and the base 3.

[0031] Please refer to Figure 2 , the fixing bolt 12 penetrates through the top through hole 6 and extends into the bottom screw hole 9, and the fixing bolt 12 is connected with the bottom screw hole 9 through threaded cooperation. The fixing bolt 12 is used to fix the adjustment block 2.

[0032] Please refer to Figure 2 , the pushing bolt 11 is connected with the side screw hole 5 through threaded cooperation. The pushing bolt 11 rotates and moves back and forth inside the side screw hole 5.

[0033] Please refer to Figure 4 and Figure 5 , limit strips 7 are arranged on both the front and rear sides of the lower end of the adjustment block 2, and the limit strips 7 are integrally formed with the adjustment block 2.

[0034] Please refer to Figure 4 and Figure 5, two limiting grooves 8 are provided at the upper end of the base 3 and below the lower end of the adjustment block 2, and the limiting grooves 8 are integrally formed with the base 3. The limiting strip 7 is adapted to the limiting grooves 8, and the combination of the limiting strip 7 and the limiting grooves 8 improves the fixing stability of the adjustment block 2.

[0035] In this solution: for precision adjustment, a gasket 13 is installed at one end of the turret. The height of the turret can be adjusted by grinding the height of the gasket 13, making the precision adjustment more convenient; in the machining process, the simple machining process and relatively simple machining precision provide conditions for cost reduction. First, the installation surface of the original spindle head 1 and the base 3 is designed as a horizontal plane. Before hoisting the spindle head 1, the installation surface on the base 3 is first subjected to scraping process. The purpose of this is first to remove the micro-rust on the casting surface, and second, the scraped installation surface reduces the contact area with the spindle head 1, making the locking force more concentrated and the locking more firm. Most importantly, this process can effectively ensure the flatness of the spindle installation surface and provide a benchmark for the overall precision of the machine tool; the biggest advantage of the horizontally installed spindle head 1 compared to the 45-degree inclined installed spindle head 1 is that the overall rigidity is better and the precision is relatively stable; in the subsequent assembly process, the precision adjustment is also relatively simple. When the parallelism between the spindle and the Z-axis is not good, the yaw of the spindle head 1 can be controlled by the pull-back bolt 10 and the push bolt 11 on the adjustment block 2, thereby controlling the parallelism with the Z-axis; when there is a deviation between the center height of the Z-axis and the tailstock and the spindle, only the gasket 13 of the turret and the tailstock needs to be taken out and ground.
