All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
As shown in fig. 1 and 2, a rectangular frame fixture comprises a fixed base 1 and a tooling frame 2, wherein the fixed base 1 is obliquely arranged with the ground, a plurality of sub-snap bases 12 are fixed on the inclined plane of the fixed base 1, the sub-snap bases 12 further enhance the connection strength through rib plates 11, and the sub-snap bases 12 are provided with bolt holes. A plurality of primary and secondary buckle bolts 21 are fixed on the tool rack 2, the primary and secondary buckle bolts 21 are arranged along the direction of the inclined plane of the fixed base 1, and the primary and secondary buckle bolts 21 are arranged in bolt holes of the primary and secondary buckle base 12. The pressing mechanisms 4 are arranged on the two side edges of the tool rack 2 in a sliding mode, the pressing mechanisms 4 arranged in a sliding mode can be positioned and pressed in a sliding mode according to specific positions on the frame, and the pressing mechanisms can be pressed in a sliding mode by specifically combining the shape and process characteristics of the frame, so that high freedom positioning and clamping are achieved, and the problem that the pressing mechanisms 4 need to be detached and adjusted in position due to the fact that certain positions are not prone to being clamped is solved.
The pressing mechanism 4 comprises a sliding seat 42, a push-pull locking clamp 41, a fixing block 43 and an air cylinder 44, wherein the sliding seat 42 is slidably arranged in the sliding groove 25 of the tooling rack, a through hole is formed in the sliding seat 42, the push-pull locking clamp 41 is fixed on the outer side surface of the sliding seat 42, the telescopic end of the push-pull locking clamp 41 is arranged in the through hole, the fixing block 43 is fixed on the end surface of the sliding seat 42, and the air cylinder 44 is arranged on the fixing block 43. When the push-pull type locking clamp 41 is pushed or pulled, the telescopic end thereof passes through the through hole of the sliding seat 42 and abuts against the inner wall of the sliding groove 25, thereby fixing the pressing mechanism 4. The position of the pressing mechanism 4 can be conveniently and quickly adjusted by the design, so that a proper position is selected to be pressed and fixed according to the specific condition of the frame.
Further, the assembly of a snap base 12 and a snap pin 21 is a limited point. According to the utility model, two limiting points are arranged on the upper sides of the fixed base 1 and the tool rack 2, and two limiting points are arranged on the lower sides of the fixed base 1 and the tool rack 2, so that the tool rack 2 is integrally placed on the inclined surface of the fixed base 1 and is in limiting connection with the snap fastener base 12 through the snap fastener bolt 21.
Further, the snap-fit bolt 21 is provided with a stepped pin shaft with a large upper section and a small lower section, the lower section of the snap-fit bolt 21 is arranged in the bolt hole of the snap-fit base 12, and the end surface of the upper section of the snap-fit bolt 21 is arranged to be tightly attached to the end surface of the snap-fit base 12.
