Abstract
The utility model relates to a special clamp tool for processing double bolt holes of a crawler belt, which is suitable for processing double bolt holes of the crawler belt. The special clamp tool is characterized in that a lever group comprises three levers, the levers are connected through pins and can move freely, and thus a part with a blank surface can be clamped; a positioning column and an adjusting hole are adopted to position the crawler belt, an eccentric cam drives the lever group and a press head to clamp and loosen the work piece, and the functions of a clamp and a drilling jig are combined. The processing can be completed through arranging the crawler belt in the tool, rotating the eccentric cam to drive the lever group to move, and clamping the work piece with the press head on the lever group. The part can be removed after processing when the eccentric cam is rotated reversely and the press head of the lever group is automatically loosened under the reacting force of springs.
Description
Technical field
The utility model is applicable to the processing of the two bolts hole of crawler belt joint in the tracked construction equipment ground-engaging element.
Background technology
Original processing technology is generally drill jig processing, and drill jig clamping part precision is low, is prone to part and drags pine and dimension overproof phenomenon, can't satisfy technology and production requirement.
The utility model content
The utility model is to overcome above-mentioned deficiency, the frock that is installed that adapts with it at the design feature design of the two bolts hole of crawler belt joint.
For realizing above purpose, take following technical scheme: this clamp fixture is made up of parts such as crawler belt joint, anchor clamps base plate, bushing plate, lever group, reference column, adjustment bolt, eccentric cam, pressure heads, it is characterized in that: the lever group is made up of three joint levers, connect with pin between the lever, the activity direction freedom, be convenient to the to be installed part of black skin utilizes reference column and adjusts bolt the crawler belt joint is played positioning action, utilizes eccentric cam to drive lever group and pressure head chucking and loosens workpiece.
The beneficial effects of the utility model: can utilize card engaging workpiece of frock, frock is in conjunction with two bolt hole drill jigs and crawler belt joint anchor clamps and one, and the processing crawler belt of high efficiency pinpoint accuracy saves bolt hole.
Description of drawings
As shown be tooling drawing.
1. crawler belt saves 2. anchor clamps base plates, 3. bushing plates, 4. lever groups, 5. reference columns 6. and adjusts bolt 7. eccentric cams 8. pressure heads
The specific embodiment
As shown in the figure, this clamp fixture is made up of parts such as crawler belt joint 1, anchor clamps base plate 2, bushing plate 3, lever group 4, reference column 5, adjustment bolt 6, eccentric cam 7, pressure heads 8, frock is placed on the upright drill workbench, adjust the position of clamp fixture, the corresponding back, position of the drill bit on the position that makes diplopore on the bushing plate 3 and the vertical drill is with T type bolting anchor clamps base plate 2.Crawler belt joint 1 is positioned on the jig frock, the position of reference column 5 and adjustment bolt 6 control parts, and eccentric cam 7 cramping lever groups 4 drive pressure heads 8 chucking parts and can process.After the completion of processing, only need opposite spin eccentric cam lever group to unclamp pressure head automatically under the reaction force of spring, part can unload.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
