Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. 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.

Traditional frame anchor clamps, because the various sizes of square tube frame, shape are various, the clamping structure of its design is just more complicated, often is provided with a plurality of fixture on one set of frock frame 2. When meeting the frame of different motorcycle types, just need to change corresponding anchor clamps this time, and what bring along is the waste of manpower, the time cost resource that frequently changes anchor clamps and lead to thereupon to still need debug after changing anchor clamps, can spend more manpower and time cost again. Of course, also have some work anchor clamps that make things convenient for the change relatively among the prior art, it often is the level setting, and in order to guarantee stability, often adopt bolted connection, compact heap to compress tightly modes such as spacing and prescribe a limit to, relatively speaking, the dismouting has certain convenience, but still is simple fast inadequately, and the mode of connecting fixedly like this still wastes time and energy when the dismouting.

According to the rectangular frame clamp, the fixed base 1 and the ground are obliquely arranged, and the fixed base 1 and the tool rack 2 are connected and limited at positions through a simple structure comprising the snap fastener base 12 and the snap fastener bolt 21. The simple structure of slope arrangement and latch connection, easy realization when guaranteeing that frock frame 2 is stable firm installing on unable adjustment base 1, can change through the dismouting of the realization frock frame 2 of convenient and fast of mode of latch connection again.

When a rectangular pipe frame in multiple states is encountered, the tool rack 2 is only required to be separated from the snap fastener bolt 21 and the snap fastener base 12 on the fixing base 1 along the inclined plane direction of the fixing base 1, and the tool rack 2 in a new state is replaced, so that the cost and time for manufacturing the same part of fixtures are greatly reduced, and meanwhile, the waste of manpower and time cost resources caused by frequently replacing the fixtures and the debugging cost and replacing the fixtures on an automatic production line when the frame state is switched is also reduced.

The two sides of the tooling frame 2 are provided with a plurality of side baffles 23, the positions of the tooling frame 2 can be limited by the side baffles 23 when the tooling frame 2 is replaced, and the tooling frame is prevented from moving and dislocating, so that the installation can be completed by quickly and accurately aligning the bolt holes of the snap fastener base 12.

Set up two at least clamping mechanism 3 on one of them side of frock frame 2, in order to guarantee the stability of frame installation on frock frame 2, set up clamping mechanism 3, can be so that one side top tight side shield 23 of frame, then one side supports tightly through clamping mechanism 3 in addition to realize the fixed of frame.

The clamping mechanism 3 adopts a push-pull type clamp, the push-pull type clamp is convenient to operate, the clamping force is large, and the stable and firm clamping of the frame is easy to realize.

The top of the tooling rack 2 is provided with a hook 22, the hook 22 can fix the frame, and the clamping mechanism 3 is combined to realize more reliable fixation.

Further, the lower end of the tool rack 2 is provided with a hidden fixing bottom plate 24. The lower side of the tool rack 2 is provided with a groove, the inner wall of the groove is connected with a fixing bottom plate 24 through a hinge connecting piece 241, and the hinge connecting piece can rotate by 90 degrees. In the initial state, the fixed base plate 24 is accommodated in the groove; when the lower side of the frame needs to be fixed, the fixing bottom plate 24 is rotated to be turned by 90 degrees and then fixed, and the fixing bottom plate 24 can support and fix the lower side of the frame. The design enriches the clamping mode of the tool rack 2 and can clamp various types of frames.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
