Description
Technical field
The utility model belongs to jig technical field, particularly relates to a kind of bent axle drilling machine special fixture.
Background technology
Bent axle, when drilling machine machining center hole, needs to carry out clamping to workpiece.Existing clamping tool is that to adopt the device such as screw to carry out machinery by fixture fixing.Because bent axle shape is special, there is clamping difficulty when clamping in existing fixture, positioning precision is poor, complex operation, and labour intensity is large, and repeated clamping precision is difficult to the shortcoming ensured.In process, particularly there is the drawback that workpiece rotates by cutting force.
Utility model content
Problem to be solved in the utility model is that existing drilling machine clamping bent axle adopts the device such as screw to carry out machinery to fix, and because bent axle shape is special, existing fixture exists clamping difficulty when clamping, positioning precision is poor, complex operation, labour intensity is large, and repeated clamping precision is difficult to ensure.
In order to solve the problems of the technologies described above, the utility model provides following scheme: bent axle drilling machine special fixture, comprises base, tailstock, bracing frame, thimble, hydraulic cylinder, fore-set, spring and tapered sleeve; Floor installation is on lathe, base tail end upper surface mounted tailstock along its length, tailstock installs thimble, thimble connecting fluid cylinder pressure, base vertically installs bracing frame, and bracing frame is provided with bent axle standing groove, thimble pilot hole, and base installs tapered sleeve with bent axle standing groove opposite position, on tailstock along its length and be positioned at bent axle lower end run through bracing frame install fore-set, pocketed springs on fore-set.The utility model is the special fixture on Crankshaft Machining drilling machine, and because the structure of bent axle, shape are special, so common clamping tool positioning precision is poor, complex operation, repeated clamping precision is difficult to ensure.Utilize bracing frame, tapered sleeve, thimble that whole bent axle is positioned clamping in the utility model.Concrete installation way is: be first placed in bent axle standing groove by the one end processed that do not need of bent axle, hydraulic cylinder drives thimble to move, and ensure that thimble presses to bent axle, now the processing end of bent axle moves gradually until withstand tapered sleeve, prevents bent axle from moving left and right.Simultaneously hydraulic cylinder drives tailstock to move, and fore-set is also moved to the left, and the spring on fore-set maintains static, and can apply reaction force like this to bracing frame, forces bracing frame to be clamped by bent axle, prevents the upper and lower play of bent axle.
Further, described tailstock is " U " shape structure, and hydraulic cylinder and thimble are all erected at its opening part, and " U " shape structure is convenient to the installation of hydraulic cylinder and thimble.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model bent axle drilling machine special fixture embodiment.
Detailed description of the invention
As shown in Figure 1: bent axle drilling machine special fixture, base 1, tailstock 2, bracing frame 3, thimble 4, hydraulic cylinder 5, fore-set 6, spring 7 and tapered sleeve 8 is comprised; Base 1 is arranged on lathe, base 1 tail end upper surface mounted tailstock 2 along its length, tailstock 2 is installed thimble 4, thimble 4 connecting fluid cylinder pressure 5, base 1 vertically installs bracing frame 3, and bracing frame 3 is provided with bent axle standing groove 9, thimble pilot hole, and base 1 installs tapered sleeve 8 with bent axle standing groove 9 opposite position, on tailstock 2 along its length and be positioned at bent axle lower end and run through bracing frame 3 and fore-set 6 is installed, pocketed springs 7 on fore-set 6.The utility model is the special fixture on Crankshaft Machining drilling machine, and because the structure of bent axle, shape are special, so common clamping tool positioning precision is poor, complex operation, repeated clamping precision is difficult to ensure.Utilize bracing frame 3, tapered sleeve 8, thimble 4 that whole bent axle is positioned clamping in the utility model.Concrete installation way is: be first placed in bent axle standing groove 9 by the processing one end that do not need of bent axle, hydraulic cylinder 5 drives thimble 4 to move, and ensure that thimble 4 presses to bent axle, now the processing end of bent axle moves gradually until withstand tapered sleeve 8, prevents bent axle from moving left and right.Simultaneously hydraulic cylinder 5 drives tailstock 2 to move, and fore-set 6 is also moved to the left, and the spring 7 on fore-set 6 maintains static, and can apply reaction force like this to bracing frame 3, forces bracing frame 3 to be clamped by bent axle, prevents the upper and lower play of bent axle.
Further, described tailstock 2 is " U " shape structure, and hydraulic cylinder 5 and thimble 4 are all erected at its opening part, and " U " shape structure is convenient to the installation of hydraulic cylinder 5 and thimble 4.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; also should be considered as protection domain of the present utility model, these all can not affect effect and the practical applicability of the utility model enforcement.
