[0024] like Figures 1-7As shown, a linear tool magazine includes a tool magazine support 1, a tool magazine body 2, a drive unit 3, and a protective component 4. Several tool magazine bodies 2 are arranged in a straight line at intervals on the tool magazine support 1. This linear arrangement of tool magazine bodies 2 is suitable for tool changing operations on multi-spindle machine tools. The drive unit 3 is mounted on the tool magazine support 1 and connected to the machine tool crossbeam 9. It drives the tool magazine support 1 and the tool magazine bodies 2 to move in a straight line, thereby moving the tool magazine bodies 2 to the tool changing position of the spindle and resetting them back to the storage position after tool changing. The protective component... 4 includes a protective door 41 and a roller assembly 42. The protective door 41 is hinged to the front end of the tool magazine support 1 and can rotate back and forth. It has contact parts 411 on both sides facing downward.

The roller 423 is rotatably connected to the fixed shaft 422 and is used to contact the contact part 411.
[0025] The working principle of this utility model is as follows: When the machine tool spindle changes tools, the drive device 3 drives the tool magazine bracket 1, the tool magazine body 2, and the protective door 41 to move toward the tool changing position. The tool magazine body 2 extends from the storage position, thus facilitating the replacement of new tools by the machine tool spindle. After the machine tool spindle has finished changing tools, the drive device 3 drives the tool magazine bracket 1, the tool magazine body 2, and the protective door 41 to move toward the storage position for reset. During the reset process, when the contact parts 411 on both sides of the protective door 41 contact the rollers 423, the protective door 41 can rotate backward around the hinge axis due to the obstruction of the rollers 423, cooperating with the front end of the machine tool crossbeam 9 to achieve a sealing effect, which can protect the internal tool magazine body 2, prevent chips from splashing into the tool magazine body 2 when the machine tool is working, ensure the cleanliness of the tool magazine body 2, and avoid damaging the tool cutting edge and affecting the tool accuracy. This utility model has a simple structure, reducing manufacturing and maintenance costs.
[0026] Optionally, a number of hinges 5 are provided between the protective door 41 and the tool magazine bracket 1. The first hinge 5 is fixedly connected to the front end of the tool magazine bracket 1, and the second hinge 5 is fixedly connected to the lower part of the protective door 41.
[0027] Optionally, the drive unit 3 includes a ball screw assembly 31 and a servo motor 32. The ball screw assembly 31 is mounted on the tool magazine support 1 along the moving direction of the tool magazine body 2. The output shaft of the servo motor 32 is connected to the lead screw of the ball screw assembly 31. A nut seat 311 is mounted on the nut of the ball screw assembly 31, and an L-shaped support plate 6 is mounted on the nut seat 311. The L-shaped support plate 6 is fixedly connected to the machine tool crossbeam 9. The servo motor 32 drives the lead screw of the ball screw assembly 31 to rotate, thereby causing the tool magazine support 1 and the tool magazine body 2 to move in a straight line relative to the nut seat 311, the L-shaped support plate 6, and the machine tool crossbeam 9. As needed, the servo motor 32 moves the tool magazine support 1 to the corresponding position, thereby facilitating the replacement of new tools by the machine tool spindle.
[0028] Optionally, linear slide rails 7 are installed on both sides of the tool magazine support 1 along the moving direction of the tool magazine body 2. A fixed seat 8 is installed on the slider of the linear slide rail 7. The fixed seat 8 is fixedly connected to the machine tool crossbeam 9. The linear slide rail 7 can provide precise guidance for the tool magazine support 1 and the tool magazine body 2.
[0029] Optionally, the tool magazine support 1 includes several longitudinal square steel tubes 11 and several transverse square steel tubes 12, which are arranged in a crisscross pattern and fixedly connected. The crisscross arrangement of the longitudinal square steel tubes 11 and transverse square steel tubes 12 results in a stable structure that is not easily deformed, thus ensuring the safety of tool storage and the accuracy of tool changing operations.
[0030] Optionally, each tool magazine body 2 includes a base plate 21 and multiple clamping slots 22 for mounting tool holders. The base plate 21 is fixed on the tool magazine bracket 1, and the multiple clamping slots 22 are distributed in a linear array on the base plate 21.
