Description

Technical Field

[0001] The utility model relates to the field of machine tools, in particular to a slider clamping structure of a gantry machining center and a machine tool comprising the slider clamping structure of the gantry machining center. Background Art

[0002] In the field of machine tools, the Y-axis of the gantry machining center is driven by a gear rack and the slide saddle is an integrated type. The linear rail slider can only be installed on the inside of the gear and needs to be pressed. In the prior art, one method is to install a pressure block, but a through hole is opened on the pressure block and a threaded hole is opened on the slide saddle. The screws need to lock the pressure block from the bottom to the top on the inside of the slide saddle, thereby pressing the linear rail slider. Due to the space limitation on the inside and the inability to observe, the installation is time-consuming and labor-intensive, and the locking torque cannot be guaranteed; another method is to directly cancel the pressure block and only lock the linear rail slider with screws. The disadvantage of this method is that it cannot guarantee the effective contact between the reference surface of the linear rail slider and the bearing surface of the slide saddle. Even if it is effectively contacted during installation, the position of the linear rail slider may change after the machine tool has been running for a period of time, resulting in unstable machine tool accuracy.

[0024] Figure 1-Figure 2 The utility model discloses a slider clamping structure of a gantry machining center, which includes a linear rail 10, a driving assembly 20, a saddle 30, a slider 40, a second locking member 50, a pressing block 60, a locking member 70 and a gasket 80.

[0025] In this embodiment:

[0026] The linear rail 10 is mounted on the crossbeam 90 .

[0027] The driving assembly 20 includes a motor 21, a reducer 22, a gear 23, and a rack 24. The rack 24 is installed on the crossbeam 90 and is located on one side of the linear rail 10. The length direction of the rack 24 is parallel to the length direction of the linear rail 10. The reducer 22 is installed on the shaft of the motor 21, and the gear 23 is installed on the shaft of the reducer 22. The motor 21 drives the gear 23 to move along the length direction of the rack 24.

[0028] The driving assembly 20 is in transmission connection with the saddle 30. The motor 21 drives the gear 23 to move along the length direction of the rack 24, and drives the saddle 30 to move along the length direction of the linear rail 10. The saddle 30 is provided with a groove portion 31 on the side facing the slider 40. The groove portion 31 is provided with a bearing surface 311. The saddle 30 is also provided with a through hole for cooperating with the locking member 70 and a second through hole for cooperating with the second locking member 50.

[0029] The slider 40 is installed on the rail 10 and is located in the groove portion 31. The slider 40 is provided with a second threaded hole. The extension direction of the second threaded hole is in the same straight line as the extension direction of the second through hole. The width of the groove portion 31 is greater than the width of the slider 40, leaving sufficient space for the installation of the pressure block 60.

[0030] The second locking member 50 is sequentially inserted into the second through hole and the second threaded hole, and is used to position the saddle 30 and the slider 40 during the initial installation, and is used to finally press and lock the saddle 30 and the slider 40. In this embodiment, there are multiple second through holes, second threaded holes, and second locking members 50, each second through hole corresponds to a second threaded hole, and each second locking member 50 is set in a second threaded hole. The second locking member 50 is a screw, a nut, a bolt, or a screw.

[0031] The pressing block 60 is arranged in the groove portion 31 and is located on one side of the slider 40 . The pressing block 60 is provided with a threaded hole. The extension direction of the threaded hole is in the same straight line as the extension direction of the through hole, so as to make the slider 40 abut against the bearing surface 311 of the saddle 30 .

[0032] The locking member 70 is sequentially inserted into the through hole and the threaded hole, and the locking member 70 is rotated to make the slider 40 abut against the bearing surface 311, thereby pressing the slider 40, ensuring that the reference surface of the slider 40 is in effective contact with the bearing surface 311 of the saddle 30. After the machine tool runs for a period of time, the position of the slider 40 relative to the saddle 30 will not change, ensuring the stability of the machine tool precision. In this embodiment, the locking member 70 is a screw, a nut, a bolt or a screw.

[0033] The gasket 80 is located between the bearing surface 311 and the slider 40 and is used to adjust the vertical accuracy of the YZ axis.

[0034] When the present application is used, the saddle 30 is first installed on the slider 40 through the second locking member 50, but the second locking member 50 is not locked. Then, the threaded hole on the pressure block 60 is aligned with the through hole of the saddle 30 by observation, and the locking member 70 is installed from top to bottom on the outside of the saddle 30, and the locking member 70 is locked on the outside at a specified torque by a torque wrench. Thus, in the process of locking the pressure block 60, the slider 40 can be close to the bearing surface 311 of the saddle 30. Finally, the second locking member 50 is locked at a specified torque with a torque wrench to lock the slider 40, so that the saddle 30 can run stably for a long time. The present application can be directly observed during installation, and the installation is fast and convenient. The present application can use a torque wrench to lock the screws at a specified torque to ensure the stability of the machine tool accuracy. In addition, when adjusting the machine tool accuracy, it is often necessary to loosen and lock the pressure block 60, which is convenient to disassemble and saves a lot of installation time.

[0035] The present application also relates to a machine tool including the above-mentioned gantry machining center slide block clamping structure.

[0036] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications and improvements can be made, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the utility model, and all of them belong to the protection scope of the utility model.
