Abstract
The invention belongs to the technical field of machine tool clamps, and particularly relates to a tool special for milling key grooves in general engine crankshafts. The tool comprises a transverse clamping part and a longitudinal clamping part, wherein the transverse clamping part comprises an installing bottom plate, multiple installing bases and hydraulic cylinders, multiple centres and limiting blocks are installed on the installing bases, and the movable ends of the hydraulic cylinders are connected with the centres; the longitudinal clamping part comprises multiple brackets, rotating clamping jaws and air cylinders, the rotating clamping jaws are installed on the brackets, and the rotating clamping jaws are driven by the air cylinders to act to clamp the crankshafts. By the utilization of the technical scheme, the key grooves in the multiple general engine crankshafts can be machined at the same time. According to the particular machining process mode, the multiple general engine crankshafts are fixed through the centres on the installing bases, the hydraulic cylinders are started at the same time to clamp the general engine crankshafts, the main purpose is to prevent the parts from moving left and right, the crankshafts are supported by the brackets, the rotating clamping jaws are driven by the air cylinders to act to clamp the crankshafts so that the crankshafts can be prevented from vertically playing, in this way, the key grooves in the multiple general engine crankshafts can be machined at the same time, the working efficiency is improved, and the production cost is reduced.
Description
Technical field
The invention belongs to lathe technical field of tooling clamps, particularly relate to a kind of logical machine crankshaft keyseat special tooling.
Background technology
Keyway on logical machine crankshaft is mainly used for coordinating with flat key, and the shortcoming of keyway is the intensity weakening axle, general only in the employing of stressed less position.The keyway of logical machine crankshaft is generally processed on Digit Control Machine Tool, and the structure due to keyway is simple but requirement on machining accuracy is higher, the processing of general employing milling machine.But existing milling machine processing adopts the keyway of a single process logical machine crankshaft usually, and cannot process in batch, production efficiency is low, considerably increases cost.
Summary of the invention
The problem to be solved in the present invention is the keyway that the processing of existing milling machine adopts a single process logical machine crankshaft usually, and cannot process in batch, production efficiency is low, considerably increases cost.
In order to solve the problems of the technologies described above, the invention provides following scheme: logical machine crankshaft keyseat special tooling, comprise horizontal clamping part and longitudinal clamping part, horizontal clamping part comprises mounting base, many group mount pads and hydraulic cylinder, mount pad is provided with many group thimbles and limited block, hydraulic cylinder movable end connecting ejector pin; Longitudinal clamping part comprises organizes bracket, turn claw and cylinder more, and turn claw is arranged on bracket, and cylinder drives turn claw action clamping bent axle.Utilize technique scheme can process keyway on multiple logical machine crankshaft simultaneously.Concrete processing mode is: utilize the thimble on mount pad to fix multiple logical machine crankshaft, and simultaneously primer fluid cylinder pressure is clamped, and this mainly prevents part from moving left and right, and utilizes limited block to limit it further move left and right fixing for logical machine crankshaft.Meanwhile, multiple bent axle is organized bracket more respectively and is held up, and cylinder drives turn claw action clamping bent axle, the upper and lower play of bent axle can be prevented, the object of the keyway simultaneously processed on multiple logical machine crankshaft can be reached like this, increase work efficiency, reduce production cost.
Further, the distance between described two adjacent groups thimble is 30 ~ 50cm, avoids two adjacent groups part to process and produces interference, such as, process scrap iron from splashing and scratch adjacent logical machine crankshaft.
Further, between described hydraulic cylinder, Timing Belt is installed, can further ensures that hydraulic cylinder works is synchronous.
Further, be provided with sliding tray and be arranged on the slide rail on lathe below described bracket, sliding tray and slide rail activity coordinate, and are convenient to the position of bracket.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the plan structure schematic diagram that machine crankshaft keyseat special tooling embodiment is led in the present invention.
Detailed description of the invention
As shown in Figure 1: logical machine crankshaft keyseat special tooling, comprise horizontal clamping part and longitudinal clamping part, horizontal clamping part comprises mounting base 1, many group mount pads 2 and hydraulic cylinder 3, and mount pad 2 is provided with many group thimbles 4 and limited block 5, hydraulic cylinder 3 movable end connecting ejector pin 4; Longitudinal clamping part comprises organizes bracket, turn claw 7 and cylinder more, and turn claw 7 is arranged on bracket, and cylinder drives turn claw 7 action clamping bent axle.Distance between described two adjacent groups thimble 4 is 30 ~ 50cm.Between hydraulic cylinder 3, Timing Belt is installed.The slide rail being provided with sliding tray 10 below bracket and being arranged on lathe, sliding tray 10 and slide rail activity coordinate.
Add man-hour, utilize technique scheme can process keyway on multiple logical machine crankshaft simultaneously.Concrete processing mode is: utilize the thimble 4 on mount pad 2 to fix multiple logical machine crankshaft, and simultaneously primer fluid cylinder pressure 3 clamp, and this mainly prevents part from moving left and right, and utilizes limited block 5 to be fixed by logical machine crankshaft to limit it further to move left and right.Meanwhile, multiple bent axle is organized bracket more respectively and is held up, and cylinder drives turn claw 7 action clamping bent axle, the upper and lower play of bent axle can be prevented, the object of the keyway simultaneously processed on multiple logical machine crankshaft can be reached like this, increase work efficiency, reduce production cost.Distance between two adjacent groups thimble 4 is 30 ~ 50cm, avoids two adjacent groups part to process and produces interference, such as, process scrap iron from splashing and scratch adjacent logical machine crankshaft.Between hydraulic cylinder 3, Timing Belt is installed, further can ensures that hydraulic cylinder 3 works synchronously.The slide rail being provided with sliding tray 10 below bracket and being arranged on lathe, sliding tray 10 and slide rail activity coordinate, and are convenient to the position of bracket.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; also should be considered as protection scope of the present invention, these all can not affect effect of the invention process and practical applicability.
