Abstract
The utility model relates to a general fixture for crankshaft drilling and milling and used in a crankshaft drilling and milling processing machine tool. The general fixture comprises a clamp body, a compress block, a fixture and a locating block, wherein a piston of an oil cylinder fixed on the fixture body is connected with a compress rod; one end of a connecting rod is connected with the compress rod, and the other end thereof is connected with a connecting rod seat; a press rod is fixed on the compress rod; and the locating block is connected with a locating block rest. When the general clamp is in use, the oil cylinder runs and the piston on the oil cylinder moves upwardly to drive the compress rod to move taking a shaft pin as an axle center, so that the press rod is in contact with the connecting rod journal of the crankshaft at first, and the connecting rod journal is compressed on the locating block of the clamp. When a press block mounted on the compress rod is compressed on the king journal of the crankshaft, the crankshaft can be completely positioned on the clamp. The utility model has the advantages of simple design, convenient use, lower cost, good use effect, high processing precision and convenient operation.

Background technology
The brill of bent axle mills processing usually with its trunnion location, use connecting rod neck orientation, because of its production process complexity, need a large amount of anchor clamps to guarantee the high accuracy and the high efficiency of Production of Crankshaft, a large amount of anchor clamps have increased the cost of Production of Crankshaft to Production of Crankshaft, the adjustment of anchor clamps has also brought huge auxiliary time of production to Production of Crankshaft, and adjustment needs certain technical requirements to anchor clamps simultaneously.
The utility model content
Goal of the invention of the present utility model will provide a kind of easy to use exactly, regulates fast, and the bent axle brill that is used for of low production cost mills the universal fixturing of processing.Technical solution of the present utility model is such: a kind of bent axle brill that is used for mills the universal fixturing of processing, a kind of bent axle brill that is used for mills the universal fixturing of processing, form by clamp body, compact heap, anchor clamps and locating piece, it is characterized in that being fixed on the piston of clamp body upper cylinder and connecting compressor arm, one end of connecting rod is connecting compressor arm, the other end of connecting rod is connected with connecting rod base, is fixing depression bar on the compressor arm, and locating piece is connected with the locating piece bearing.During use, size according to institute's machining crankshafts, adjust the size and the distance of universal fixturing, install the bent axle of required processing, the operation oil cylinder, piston on the oil cylinder moves upward, driving compressor arm is axe movement with the pivot pin, makes depression bar at first contact the connecting rod neck of bent axle, the connecting rod neck is pressed on the locating piece of anchor clamps, after being installed in briquetting on the compressor arm and compressing the trunnion of bent axle, bent axle will have been located on anchor clamps fully.When adjusting anchor clamps, only need unclamp the T type screw on the anchor clamps, press the distance mobile anchor clamps on workbench between the location trunnion of crankshaft two end, satisfy the clamping requirement of anchor clamps, just can finish the adjustment of anchor clamps according to the replaceable compact heap of the variation of main bearing journal size.The use the beneficial effects of the utility model are, jig Design is simple, and is easy to use, and cost is lower, and result of use is good, and the machining accuracy height is convenient to operation.
Description of drawings
Fig. 1 is the front view of the utility model on workbench.
Fig. 2 is Figure 1A-A cutaway view.
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
Among Fig. 1, anchor clamps 3 and rear jig 2 are located on workbench 1 by being installed on the workbench 1 positioning key 4, and locating piece 19 is connected with the dovetail guide form with locating piece bearing 21.Depression bar 6 is fixed on the compressor arm 15 by bolt 5, and spring 10 is installed on the depression bar 6.
Among Fig. 2, anchor clamps 3 usefulness T type screws 22 are fixed on the workbench 1, anchor clamps 3 are by clamp body 24, piston 14, connecting rod 16, compressor arm 15, compact heap 17, the anchor clamps 18 of V-type and locating piece 19 are formed, anchor clamps 18 can to bent axle axially, horizontal direction and vertical side's location, piston 14 is installed in the oil cylinder 30 on the clamp body 24, use oil cylinder cover 13 up and down, 23 compress, piston 14 is connected with compressor arm 15 usefulness bearing pins 26, one connecting rod base 27 is installed on clamp body 24, connecting rod 16 and connecting rod base 27, compressor arm 15 usefulness bearing pins 31,32 connect, anchor clamps 18 are installed on the clamp body 24, on the next door of anchor clamps 18, anchor clamps locating piece 19 and locating piece bearing 21 are installed on clamp body 24, its effect is to the bent axle axial location, locating piece 19 is connected with the dovetail guide form with locating piece bearing 21, with screw 20 lockings.Hydraulic oil enters oil cylinder from the joint 11 on the clamp body 24, piston 14 moves upward, the hydraulic oil on piston 14 tops is pushed back fuel tank by joint 12, compressor arm 15 is the center of circle with bearing pin 26, under the pulling of connecting rod 16, clockwise rotate, simultaneously, connecting rod 16 can be that the center of circle clockwise rotates with bearing pin 26 also, when compressor arm 15 turns to certain angle, be installed in the connecting rod neck that depression bar 6 on the compressor arm 15 at first contacts bent axle, spring 10 is compressed, and bent axle is that the center of circle rotates counterclockwise with the trunnion center line, the connecting rod neck is pressed on the locating piece 19 of anchor clamps, after being installed in briquetting 17 on the compressor arm 15 and compressing the trunnion of bent axle, bent axle will have been located on anchor clamps fully, when anchor clamps need be opened, and joint 12 oil-feeds, joint 11 oil returns, its principle is just in time opposite with clamping.
More stable in order to make bent axle add man-hour, in the corresponding place of workbench 1 rear jig 2 has been installed, be used to clamp crankshaft two end.Do not have locating piece 19 these covering devices on the rear jig 2, all the other structures are identical with anchor clamps 3, and operation principle also is the same, the oil-feed of rear jig 3, anchor clamps 2 is same oil pipe fuel feeding, same oil pipe oil return, like this, rear jig 3, anchor clamps 2 are anchor clamps and having opened simultaneously just.
Among Fig. 3, in conjunction with Fig. 1 and Fig. 2, when needs are processed the bent axle of different model, adjustment to anchor clamps, only need unclamp the T type screw 22 on rear jig 3, the anchor clamps 2, press distance between the location trunnion of crankshaft two end on workbench, move before and after anchor clamps, unclamp screw 20, the height of adjustable whole locating piece 19 unclamps screw 28, can adjust the circumferentially front and back position of location of bent axle, unclamp screw 29, locking nut 8, can adjust the circumferentially position, the left and right sides of location of bent axle, the replaceable compact heap 17 of the variation of main bearing journal size satisfies the clamping requirement of anchor clamps.Like this, only need to change compact heap 17, the clamping and positioning that just can satisfy all bent axles has basically required.
