DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1 , Figure 2As shown in Figure 4, in this embodiment, the clamping mechanism for high-precision aluminum guide rail cutting includes a base plate 1, which is characterized in that: a mounting plate 2 is fixedly installed on the top outer wall of the base plate 1, and a clamping assembly 7 is installed on both sides of the mounting plate 2. The clamping assembly 7 includes a receiving block 701 fixedly connected to one side of the top outer wall of the mounting plate 2, and one side of the top outer wall of the mounting plate 2 is rotatably connected to two screw rods 703, and the two screw rods 703 are threadedly sleeved with the same extrusion frame 704, and two symmetrically arranged baffles 705 are slidably connected in the extrusion frame 704. The inner walls at both ends of the extrusion frame 704 are rotatably connected to the same bidirectional screw rod 706, and the two baffles 705 are respectively threadedly sleeved on the two ends of the bidirectional screw rod 706. The top outer wall of the receiving block 701 is provided with two symmetrically arranged accommodating grooves 702, and the two baffles 705 are respectively slidably inserted into the two accommodating grooves 702.

[0024] A sprocket 708 is coaxially fixed to the outer wall of the top of two screw rods 703 on one side, and the two sprockets 708 are sleeved with the same chain 709.

[0025] The positions of the two baffles 705 are adjusted according to the width of the guide rail to be cut, and the bidirectional screw rod 706 is driven to rotate in the extrusion frame 704 by the rotating rod 707. The two baffles 705 sliding in the extrusion frame 704 will be driven by the bidirectional screw rod 706 to move toward each other, thereby ensuring that the two baffles 705 can fit exactly on the two sides of the guide rail. Then the guide rail is passed through the two clamping assemblies 7, and then the extrusion frame 704 and the two baffles 705 are driven toward the guide rail by the screw rod 703. At this time, the extrusion frame 704 cooperates with the receiving block 701 to tightly fix the upper and lower sides of the guide rail.

[0026] like Figure 1 and Figure 3 As shown, a mounting block 4 is fixedly connected to both sides of the top outer wall of the mounting plate 2, and the two mounting blocks 4 are rotatably connected to the same rotating shaft 3. A bevel gear 5 is fixedly provided at both ends of the rotating shaft 3, and a bevel gear 2 8 is fixedly provided at the two screw rods 703 at one end. The two bevel gears 5 are respectively meshed with the two bevel gears 2 8.

[0027] The thread grooves of the two screw rods 703 at one end have the same parameters except for the opposite rotation directions. Since the two screw rods 703 at one end will be driven by the bevel gear 2 8 to rotate in opposite directions, if their rotation directions are opposite, it can ensure that the two extrusion frames 704 move in the same direction.

[0028] The transmission wheel 6 drives the rotating shaft 3 to rotate between the two mounting blocks 4, and the two bevel gears 1 5 will also rotate synchronously with the rotating shaft 3. The bevel gear 1 5 can drive the two bevel gears 2 8 to rotate in the opposite direction through meshing, and then the two screw rods 1 703 connected to the bevel gear 2 8 will also rotate. This screw rod 1 703 can drive the other two screw rods 1 703 to rotate synchronously through the sprocket 708 and the chain 709. At this time, the two extrusion frames 704 will be driven to be extruded toward the track.

[0029] like Figure 2 As shown, the outer walls of one side of the two extrusion frames 704 are rotatably connected to a rotating rod 707 , and the rotating ends of the two rotating rods 707 are coaxially fixed to two bidirectional screw rods 706 , respectively. The bidirectional screw rods 706 can be controlled to rotate by the rotating rod 707 .

[0030] like Figure 1 As shown, a transmission wheel 6 is fixedly sleeved in the middle of the rotating shaft 3, and the diameter of the transmission wheel 6 is much larger than the diameter of the rotating shaft 3, which can increase the rotating force arm of the rotating shaft 3, thereby making the driving process more labor-saving.

[0031] The utility model provides a clamping mechanism for high-precision aluminum rail cutting, and the specific working principle is as follows:

[0032] When the device is working, first adjust the position of the two baffles 705 according to the width of the guide rail to be cut, and drive the bidirectional screw rod 706 to rotate in the extrusion frame 704 through the rotating rod 707. The two baffles 705 sliding in the extrusion frame 704 will be driven by the bidirectional screw rod 706 to move towards each other, thereby ensuring that the two baffles 705 can just fit the two sides of the guide rail. Then, the guide rail is passed through the two clamping assemblies 7, and then the extrusion frame 704 and the two baffles 705 are driven to approach the guide rail through the screw rod 1 703. At this time, the extrusion frame 704 cooperates with the receiving block 701 can tightly fix the upper and lower surfaces of the guide rail. The driving process is that the transmission wheel 6 drives the rotating shaft 3 to rotate between the two mounting blocks 4, and the two bevel gears 5 will also rotate synchronously with the rotating shaft 3. The bevel gear 5 can drive the two bevel gears 8 to rotate in the opposite direction through meshing, and then the two screw rods 1 703 connected to the bevel gear 2 8 will also rotate. This screw rod 1 703 can drive the other two screw rods 1 703 to rotate synchronously through the sprocket 708 and the chain 709. At this time, the two extrusion frames 704 will be driven to be extruded toward the track.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
