[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0025] A fast and convenient fixture for machining centers, see Figures 1 to 3 , comprising a base 1, a group of clamping mechanisms 2 are symmetrically arranged on the surface of the base 1, a group of fixing frames 3 are symmetrically fixed on the top of the group of clamping mechanisms 2, and a top-supporting mechanism 4 is arranged inside the fixing frame 3;

[0026] The push mechanism 4 includes a pressure strip 401, which is engaged with the inside of the clamping mechanism 2. A group of pressure strips 401 is provided inside the clamping mechanism 2. The ends of a group of pressure strips 401 are respectively connected to a slide bar 1 402 and a slide bar 2 403, wherein one end of the pressure strip 401 is T-shaped, and a group of pressure strips 401 are respectively formed integrally with the slide bar 1 402 and the slide bar 2 403. The slide bar 1 402 and the slide bar 2 403 are externally movable sleeved with a limiting groove frame 404. Furthermore, the slide bar 1 402 and the slide bar 2 403 are engaged with each other in parallel inside the limiting groove frame 404. The bottom of the limiting groove frame 404 is on the same horizontal line as the bottom of the pressure strip 401, and the top of the limiting groove frame 404 is connected to a hydraulic cylinder 405. The utility model effectively drives the limit slot frame 404 to move downward through the hydraulic cylinder 405, thereby driving the sliding bar 1 402 and the sliding bar 2 403 inside the limit slot frame 404 to move downward, and then driving the pressure bar 401 to move downward, so that the pressure bar 401 and the processing object can be quickly fitted together, and the processing object can be effectively limited. The activation of a single hydraulic cylinder 405 makes it easy to limit the two ends of the processing object in a group of clamping frames 206 on the same side at the same time, thereby improving the limiting efficiency.

[0027] It is worth noting that the clamping mechanism 2 includes an electric push rod 201, which is arranged on the inner wall of the base 1. The movable end of the electric push rod 201 is connected to a movable slot frame 202. Furthermore, the movable slot frame 202 forms a telescopic structure with the base 1 through the electric push rod 201. There are two groups of electric push rods 201. A motor 203 is provided on the surface of the movable slot frame 202. The movable end of the motor 203 is connected to a forward and reverse screw rod 204. A group of threaded blocks 205 are symmetrically sleeved on the surface of the forward and reverse screw rods 204. Furthermore, the motor 203 forms a threaded transmission structure with the threaded block 205 through the forward and reverse screw rods 204. A clamping frame 206 is fixed to the top of the threaded block 205, wherein a clamping slot is opened on the side of the clamping frame 206, and the pressure strip 401 is movably engaged with the inside of the clamping slot on the side of the clamping frame 206. In the utility model, the electric push rod 201 effectively drives the movable slot frame 202 to move, thereby adjusting the spacing between a group of movable slot frames 202, and then effectively drives the forward and reverse screw rods 204 to rotate through the motor 203, thereby driving a group of threaded blocks 205 on the same side to move away from or closer to each other, and then adjusting the spacing between a group of clamping frames 206 on the same side, which can be adapted to clamp processing objects of different sizes, thereby improving the applicability of the clamp.

[0028] Working principle: The fixture is installed on the workbench of the machining center through the base 1. The position of the bracket 206 is adjusted according to the size of the workpiece to be clamped. First, the electric push rod 201 drives the movable slot frame 202 to move, so as to adjust the spacing between a group of movable slot frames 202. Then, the motor 203 drives the positive and negative screw rods 204 to rotate, so as to drive a group of threaded blocks 205 on the same side to move away from or close to each other, and then adjust the spacing between a group of brackets 206 on the same side. At this time, the workpiece can be clamped appropriately. When the bracket 206 moves to the middle of the fixed frame 3, the pressure strip 401 will not affect The translation of the bracket 206, when the bracket 206 moves toward the end of the fixed frame 3, can drive the pressure strip 401 and the slide bar 1 402 and the slide bar 2 403 to translate. During the movement, the slide bar 1 402 and the slide bar 2 403 are still engaged in the limit slot frame 404, and the horizontal stability of the pressure strip 401 can still be maintained. Then, the limit slot frame 404 is driven downward by the hydraulic cylinder 405, thereby driving the slide bar 1 402 and the slide bar 2 403 inside the limit slot frame 404 to move downward, and then driving the pressure strip 401 to move downward, so that the pressure strip 401 can be quickly fitted with the processing object, and the processing object can be limited by the top, so as to complete the fixation of the processing object.
