The inlet end and the control end of the valve group are respectively connected to the external oil circuit, and the outlet end of the valve group is connected to the electric spindle through the oil circuit.

[0010] A connecting socket is provided on the top of the ram, and the cooling pipeline connected to the electric spindle is positioned through the connecting socket.

[0011] A protective cover is provided at the front end of the ram, and the length of the protective cover covering the ram is greater than the maximum length of the ram extending out of the wall protection.

[0012] A scraping plate is provided on the inner surface of the opening of the wall protection, and the scraping plate is slidably matched with the protective cover.

[0013] The high-speed spindle box suitable for wall protection in this application adopts the above structure and has the following advantages:

[0014] 1. The ram is driven by a linear motor and can move at high speed, improving processing efficiency;

[0015] 2. The ram adopts a hollow frame structure, which can be used for water or air ventilation to meet the functions of electric spindle cooling, ring spraying, taper hole cleaning, tool holder blowing, airtight protection, etc., saving the external space of the machine tool;

[0016] 3. The moving position of the ram is fed back through the grating ruler, and the stroke is closed-loop controlled to improve the processing accuracy;

[0017] 4. The protective cover is used in conjunction with the scraper plate to keep the chips and coolant in the processing area of ​​the wall protection, thus protecting the equipment and environment outside the processing area;

[0018] 5. The spindle box is equipped with a guide rail lock, which can lock the guide rail in an emergency to limit the movement of the spindle box and play a safety role. At the same time, buffers and stop blocks are installed on both sides of the spindle box to limit the travel of the spindle box. The buffer can absorb part of the energy and reduce the impact.

[0019] 6. A valve group is installed at the end of the spindle box to control the loosening and broaching action of the electric spindle. Since the valve group is directly installed on the slide and is close to the electric spindle, it reacts quickly and has a short response time. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figures 1 to 4 As shown, a high-speed spindle box suitable for wall protection is provided at the opening of the wall protection 13, and the spindle box includes an electric spindle 3, a ram 8 and a guide rail 9; Figure 3As shown, the ram 8 is a hollow frame structure, and the electric spindle 3 is connected to the front end of the ram 8 through the spindle mounting hole 8-1; a protective sheet 12 is connected to the lower surface of the ram 8, and a linear motor 11 is connected to the protective sheet 12; two guide rails 9 are arranged in parallel on the bottom surface of the ram 8, and the guide rails 9 are located on both sides of the linear motor 11, and the sliders of the guide rails 9 and the base of the linear motor 11 are respectively connected to fixed positions of the machine tool.

[0026] A guide rail lock 10 is connected to the ram 8 , and a locking portion of the guide rail lock 10 is connected to a sliding rail portion of the guide rail 9 . The guide rail lock 10 can be locked when the spindle box is not moving, thereby ensuring the stability of the structure.

[0027] A stop block 5 and a buffer 6 are provided at the two extreme positions on the side surface of the slide 8. When the spindle box needs to stop urgently, the buffer 6 first collides with the external limit structure to absorb part of the kinetic energy and reduce the impact. Then the stop block 5 contacts the external limit structure to realize the stopping function at the extreme position.

[0028] A grating ruler 7 is provided on the side surface of the ram 8 and is arranged along the bottom edge of the ram 8 in the length direction. The grating ruler 7 can timely feedback the feed amount, thereby realizing closed-loop control of the electric spindle.

[0029] A valve group 4 is provided at the rear end of the slide 8. The valve group 4 is composed of several control valves. The inlet end and the control end of the valve group 4 are respectively connected to the external oil circuit. The outlet end of the valve group 4 is connected to the electric spindle 3 through the oil circuit. The valve group 4 controls the loosening and drawing action of the spindle.

[0030] A pipe socket 1 is provided on the top of the ram 8, and the cooling pipe connected to the electric spindle 3 is positioned through the pipe socket 1. In addition to the cooling pipe, other water pipes, circuits and other structures can also be positioned through the pipe socket 1 to ensure the stability of each accessory during operation.
