Description

Technical Field

[0001] The utility model relates to the technical field of horizontal machining centers, and specifically, to a clamping mechanism of a horizontal machining center with a protection function. Background Technique

[0002] A horizontal machining center refers to a machining center with a spindle axis parallel to the workbench, which is mainly applicable to machining box-shaped parts. Its working principle is that after the workpiece is clamped once on the machining center, the computer can automatically select different tools, automatically change the spindle speed of the machine tool, and sequentially complete the machining of multiple processes on multiple surfaces of the workpiece.

[0003] After retrieval, the utility model patent with the publication number of CN218110052U discloses a clamping mechanism for a horizontal machining center, including a workbench. Clamping mechanisms are arranged on both the left and right sides of the upper end surface of the workbench. Both clamping mechanisms include a support seat and a mounting disk. The mounting disk is rotatably installed on the support seat. A rotating shaft is arranged on the mounting disk. The left rotating shaft extends outwards through the support seat, and a driving motor is connected to the outer end of the left rotating shaft. The driving motor is connected to an external power supply. T-shaped plates are slidably arranged on both the upper and lower sides of the two mounting disks. Chute grooves are correspondingly opened on the two mounting disks for multiple T-shaped plates. Clamping plates are detachably arranged on multiple T-shaped plates. Mounting plates are correspondingly arranged on multiple clamping plates for the T-shaped plates. The T-shaped plates and the mounting plates are connected by bolts; the design of the clamping plate facilitates the clamping of raw materials of different models; the design of the sliding block facilitates the clamping of raw materials of different lengths; the design of the protective cover protects the driving motor.

[0004] However, the above patent still has the following deficiencies: When machining a columnar workpiece fixed between the two mounting disks, the generated waste chips and coolant are likely to enter the adjustment groove, affecting the threaded transmission between the adjustment shaft and the sliding block; in addition, when the clamping plate clamps the columnar workpiece, the generated waste chips and coolant are also likely to enter the chute groove, affecting the smooth movement of the T-shaped plate. For this reason, we propose a clamping mechanism of a horizontal machining center with a protection function. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a clamping mechanism of a horizontal machining center with a protection function.

A second protective shell 19 is fixedly connected to the side surface of the support base 8 and located outside the brake motor 10.

[0031] In this embodiment, the double-shaft motor 14 is used to drive the two threaded rods 15 to rotate. Through the threaded cooperation between the two threaded rods 15 and the two telescopic columns 16, the two telescopic columns 16 move synchronously closer or synchronously farther away.

[0042] Working principle: When in use, first, the workbench 1 is installed on the horizontal machining center through the cooperation of the mounting base 24, the mounting holes 25 and the bolts, and the columnar workpiece to be clamped is placed between the two mounting disks 11. Then, the servo motor 4 is started to drive the bidirectional lead screw 3 to rotate. Through the threaded cooperation between the bidirectional lead screw 3 and the two sliding seats 5, the two sliding seats 5 approach each other. The sliding seat 5 drives the moving plate 6, the L-shaped bracket 7, the support seat 8 and the mounting disk 11 to move, so that the end faces of the two mounting disks 11 are in contact with the end faces of the columnar workpiece. Then, the biaxial motor 14 is started to drive the two threaded rods 15 to rotate. Through the threaded cooperation between the two threaded rods 15 and the two telescopic columns 16, the two telescopic columns 16 approach each other. Thus, the telescopic column 16 drives the L-shaped clamping frame 17 and the clamping plate 18 to move, and the clamping plate 18 is used to clamp and fix the columnar workpiece. Finally, the workpiece is machined by the horizontal machining center. In addition, the brake motor 10 is started to drive the mounting disk 11 and the columnar workpiece to rotate, so as to adjust the machined surface, and that's it.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
