Description

Technical Field

[0001] This utility model relates to the field of boring machine spindle compensation technology, specifically to an automatic compensation system for a large boring machine spindle. Background Technology

[0002] A patent document with publication number CN215432763U discloses a thermal expansion compensation system for the slide of a heavy-duty CNC floor-type milling and boring machine. This system primarily addresses the problem of thermal expansion of the slide in existing milling and boring machines affecting the machining accuracy of the machine tool. Its key feature is that the spindle is fixed to the front end of the slide, and the data acquisition device includes a grating ruler and a reading head. The reading head is fixed to the front end of the slide, and the grating ruler is fixed to the spindle box. This compensation system automatically monitors and compensates for positional changes caused by thermal expansion of the slide front end using the grating ruler, thereby ensuring that the position of the machine tool spindle is not affected by the thermal expansion of the slide and guaranteeing the machining accuracy of the machine tool.

[0003] However, in the actual operation of large boring machines, the spindle is subjected to a variety of complex external forces. There are still some shortcomings in the design of the support and buffer components. When the spindle is subjected to a large external impact, its stability may be affected. Without buffer protection, the spindle and related components will be subjected to excessive stress, which may accelerate the wear of the components. Therefore, optimization and improvement can be carried out.

[0004] Therefore, this utility model proposes an automatic compensation system for the spindle of a large boring machine to solve the above problems. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, not all embodiments, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0020] Example 1: Please refer to Figures 1 to 2 An automatic compensation system for a large boring machine spindle includes a main body 1, a spindle box mounting base 2, and a torque motor 3. The main body 1 is fixedly mounted on the spindle box mounting base 2, and the torque motor 3 is fixedly mounted inside the spindle box mounting base 2. The system also includes a compensation component 4, a fixing component 5, and a buffer component 6. The compensation component 4 is mounted on the main body 1, the fixing component 5 is fixedly mounted on one side of the main body 1, and the buffer component 6 is fixedly mounted on the fixing component 5.

[0021] The rotating spindle 401 in the compensation assembly 4 is fixedly installed in the spindle box mounting base 2. A second mounting base 402 is fixedly installed on the other end of the spindle box mounting base 2. A gear 403 is provided at the bottom of the rotating spindle 401.

[0022] When in use, start the equipment, the torque motor 3 starts to run, driving the rotating spindle 401 in the spindle box fixed seat 2 to rotate. The gear 403 at the bottom of the rotating spindle 401 rotates accordingly, providing basic power for subsequent processing. At this time, the compensation component 4 enters the initial working state, and the main body of the equipment 1 is kept stable by relying on the spindle box fixed seat 2, ready to carry out boring machine processing operations.

[0023] Example 2: Based on Example 1, please refer to... Figures 2 to 3 Hydraulic brake devices 404 are fixedly installed on both sides of the rotary spindle 401 in the compensation component 4, and a boring machine spindle box 405 is fixedly installed on the other side of the rotary spindle 401. A gyroscope sensor 406 is installed inside the boring machine spindle box 405.

[0024] The boring machine spindle box 405 in the compensation component 4 drives a machining axis 407. A workpiece model 408 is set on one side of the machining axis 407 and is set on the worktable 409.

[0025] During operation, as the rotary spindle 401 rotates continuously, it drives the boring machine spindle box 405 to run. During the machining process, the gyroscope sensor 406 inside the boring machine spindle box 405 monitors the horizontal position change of the spindle box in real time. When it is necessary to adjust the speed of the rotary spindle 401 or stop it, the hydraulic brake device 404 takes effect. At the same time, the boring machine spindle box 405 drives the machining axis 407 to machine the workpiece model 408 placed on the worktable 409. Once the gyroscope sensor 406 detects that the spindle box tilts due to gravity or other factors, it will output a signal. After receiving the signal, the system converts the signal through a compensation algorithm and applies it to the torque motor 3, driving the gear set to rotate around the main rotary axis 3, thereby adjusting the pitch angle of the boring machine spindle box 405 and compensating for the sag to ensure machining accuracy.

[0026] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The bottom end of the support telescopic cylinder 501 in the sturdy component 5 is provided with a second motor 502, the top of the support telescopic cylinder 501 is provided with a support frame 503, and a buffer pad 504 is fixedly provided on the support frame 503.

[0027] The first buffer cylinder 601 in the buffer assembly 6 is evenly arranged inside the buffer pad 504, and the second buffer cylinder 602 is embedded outside the first buffer cylinder 601. A spring 603 is fixedly arranged inside the second buffer cylinder 602.

[0028] In use, the second motor 502 drives the support telescopic cylinder 501 to extend and retract according to the actual needs of the equipment operation, thereby adjusting the position of the top support frame 503 and buffer pad 504 to provide stable support for the main body 1 of the equipment. When the equipment is subjected to a large external force impact during processing, the first buffer cylinder 601, the second buffer cylinder 602 and the spring 603 in the buffer pad 504 work together. The external force first acts on the first buffer cylinder 601, and the first buffer cylinder 601 moves in the second buffer cylinder 602, compressing the spring 603. The elastic force of the spring 603 buffers and absorbs the external force, effectively reducing the stress on the spindle and related components inside the equipment, improving the stability of the spindle, extending the service life of the equipment, and ensuring the continuous and stable operation of the equipment and the smooth progress of processing.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
