Abstract

The utility model discloses a universal fixture for processing boxes, which comprises at least two clamping mechanisms capable of clamping a to-be-processed box. Each clamping mechanism is formed by symmetrically connecting two right angle type bending arms capable of moving along a radial direction of each clamping mechanism. The universal fixture adopts the movable bending arms to adjust length of the clamping mechanisms, and leads the clamping mechanisms to clamp boxes with different specification sizes. Compared with original single fixtures, the universal fixture has high utilization and universality and is simpler and easier for processing and manufacturing.

Further, described two bending arms are fixedly connected by a plate, and described two bending arms removably connect with described connecting plate respectively.

Particularly, described connecting plate is a hollow structure, described two bending arms are sheathed on the two ends of described connecting plate respectively, are equipped with the locating hole of a plurality of arranged radiallys on described connecting plate and the bending arm, and described connecting plate is fixedlyed connected by the reference column that is arranged in the corresponding locating hole with the bending arm.

Further, be provided with micro-adjusting mechanism between the clamping face of described clamping device and casing to be processed, described micro-adjusting mechanism comprise cushion block, with described cushion block be fixed on the casing to be processed holding screw and pass to the adjustment screw that terminates in described cushion block in box house to be processed, the bending end of described bending arm clamping casing to be processed is provided with the through hole corresponding with described holding screw.

Further, described micro-adjusting mechanism also comprises the saddle shaped washer of being located between described adjustment screw and the casing.

The universal fixturing that the utility model provides, utilize its movably the bending arm adjust the length of clamping device, but make the casing of its clamping different specification size, more original fixing anchor clamps, its utilization rate height, have versatility, this clamp structure is also simple than original anchor clamps simultaneously, is easier to processing and manufacturing.

The specific embodiment

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Please refer to Fig. 2 to Fig. 4, universal fixturing 1 and casing 2 clamping schematic diagrames to be processed among the utility model embodiment.The described universal fixturing 1 that is used for casing processing comprises at least two clamping devices 11 that can clamp casing 2 to be processed, and described clamping device 11 can be formed by connecting along square bending arm 111 symmetries that the clamping device radial direction moves by two.The universal fixturing 1 that the utility model provides, utilize its movably bending arm 111 adjust the length of clamping device 11, but make the casing of its clamping different specification size, more original single anchor clamps, its utilization rate height, have versatility, this clamp structure is also simple than original anchor clamps simultaneously, is easier to processing and manufacturing.

Below each part of present embodiment is further described in detail.

With reference to Fig. 5 to Fig. 8, described two bending arms 111 are fixedly connected by a plate 112, and described two bending arms 111 removably connect with described connecting plate 112 respectively.Particularly, as shown in FIG., described connecting plate 112 is a hollow structure, described two bending arms 111 are sheathed on the two ends of described connecting plate 112 respectively, described connecting plate 112 is provided with first locating hole 1121 of a plurality of arranged radiallys, described bending arm 111 is provided with second locating hole 1111 of a plurality of arranged radiallys, and described connecting plate 112 is fixedlyed connected by the reference column 113 that is arranged in the corresponding locating hole with bending arm 111.When the casing of need clamping different size, take off reference column 113, bending arm 111 relative connecting plates 112 are stretched or the suitable displacement of indentation, first locating hole 1121 on the connecting plate 112 and second locating hole 1111 on the bending arm 111 also can relatively move at this moment, reference column 113 passed move the first corresponding locating hole 1121 of back and connecting plate 112 can be retightened with bending arm 111 with second locating hole 1111 and be connected, thereby realize the adjustment of clamping device length, but make the casing of its clamping different size, improved the utilization rate of anchor clamps.
