Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is as the effect of the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part and operation principle, manufacturing process and operation using method etc., be described in further detail, to help, those skilled in the art conceive utility model of the present utility model, technical scheme has more complete, accurate and deep understanding.
As Figure 1-3, a kind of positioner ensureing workpiece assembling concentricity, this device comprises handle 1, compresses boss 2, first alignment pin 3, second alignment pin 4 and cone pin 41.Conveniently alignment pin inserts in Workpiece fixing hole, and the profile of described handle 1, compression boss 2, first alignment pin 3 and the second alignment pin 4 is all cylindric, and described cone pin 41 is conical.Handle 1 is mutually vertical with compression boss 2, and the middle part of handle 1 is connected with the end winding support compressing boss 2.Compression boss 2 is connected with the end winding support of the first alignment pin 3 away from one end of handle 1.First alignment pin 3 is connected with the end winding support of the second alignment pin 4 away from the one end compressing boss 2.Second alignment pin 4 is fixedly connected with the large-diameter end of cone pin 41 away from one end of the first alignment pin 3.In order to ensure concentricity of workpiece, the axis of described compression boss 2, the axis of the first alignment pin 3, the axis of the second alignment pin 4 and the axis of cone pin 41 overlap.
Ensure a positioner for workpiece assembling concentricity, this device inserts in the fabrication hole on workpiece to be processed (needing to ensure the workpiece of concentricity), and the diameter of described second alignment pin 4 equals the internal diameter of fabrication hole.In order to ensure seamlessly transitting of cone pin 41 and the second alignment pin 4 junction, the major part cross section of described cone pin 41 is circular, and its radius equals the radius of the second alignment pin 4.In order to smoothly insert workpiece to be processed and can not scratch workpiece, the tip of described cone pin 41 is half round dot, the center line of half round dot and the dead in line of cone pin 41 tangent with the bus of cone pin 41.
In order to the concentricity of the workpiece (the first workpiece and second workpiece) mutually superposed two is consistent, the diameter of described first alignment pin 3 is greater than the diameter of the second alignment pin 4, and the diameter of the second alignment pin 4 equals the diameter of the fabrication hole on the workpiece of bottom in the workpiece of superposition mutually, the diameter of the first alignment pin 3 equals the diameter of the fabrication hole on the workpiece of the workpiece middle and upper part of superposition mutually.In order to be placed on by this device on workpiece to be processed, the diameter of described compression boss 2 is greater than the diameter of the first alignment pin 3.This device inserts in the fabrication hole of workpiece to be processed, the diameter of the first alignment pin 3 is consistent with the diameter of the fabrication hole of the workpiece be mated with the diameter of the second alignment pin 4, compressing boss 2 is pressed on workpiece to be processed due to Action of Gravity Field, effectively can ensure concentricity of workpiece like this, and practicality simple to operate, cost is low, reduces the working strength of workman, improves production efficiency.
As further improvement of the utility model, because the thickness of workpiece to be processed is different, therefore the length of the length of the first alignment pin 3 and the second alignment pin 4 should be set to Telescoping, and the maximum gauge of the maximum gauge of the first alignment pin 3 and the second alignment pin 4 all can not change; Therefore described first alignment pin 3 and the second alignment pin 4 are all be made up of with an expansion link being connected two sections of column structures two sections of column structures.The described axis of two sections of column structures and the axis of expansion link overlap, and the telescopic direction of expansion link is along axis direction.In order to increase the telescopic extensions of the first alignment pin 3 and the second alignment pin 4 and reduce the minimum length of the first alignment pin 3 and the second alignment pin 4, described two sections of column structures are hollow core structures, and the hollow that described expansion link is arranged on two sections of column structures is inner.
As further improvement of the utility model, in order to reduce the construction weight of positioner ensureing workpiece assembling concentricity, described handle 1, compressing between boss 2, first alignment pin 3, second alignment pin 4 and cone pin 41 and connected by welding manner.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.The protection domain that protection domain of the present utility model should limit with claims is as the criterion.
