Description
Technical field
The utility model relates to the Machining Technology field, and specifically a kind of easy to operate, accurate positioning also can improve the horizontal lathe positioning tool of workpiece precision and quality.
Background technology
In the parts machining process, has the circular shaft that two external diameters vary in size on existing many parts, and the requirement on machining accuracy of circle concentricity is in 0.05, and two circular shafts can't adopt a procedure to machine, can only adopt the processing of twice manufacturing procedure, this just needs positioning tool that workpiece is located accurately, and at present normal three-jaw gripping or the general frock of adopting carried out the clamping requirement that all is beyond one's reach, and systematic error is larger.
Summary of the invention
The purpose of this utility model is the defective for prior art, a kind of easy to operate, accurate positioning is provided and can improves the horizontal lathe positioning tool of workpiece precision and quality.
The purpose of this utility model solves by the following technical programs:
A kind of horizontal lathe positioning tool, comprise base, the middle part that it is characterized in that described base is provided with the tapering mandrel that is fixedly installed, the middle part of tapering mandrel is provided with the screwed hole of opening upwards, tapering mandrel upper cover is provided with elastic expansion sleeve, elastic expansion sleeve is fixedly linked by bolt and the tapering mandrel that is complementary with screwed hole, and the inwall of elastic expansion sleeve is provided with the conical surface that the outer wall with the tapering mandrel is complementary.
Described base is provided with regulates supporting, and described adjusting supporting axle centered by the tapering mandrel is evenly distributed on the base.
The inboard of described adjusting supporting is provided with the stud corresponding with it, and the lower end of stud is fixedly installed on the base, and the top of stud is provided with an end and is positioned at the pressing plate of regulating the supporting top, and the top of stud is provided with packing ring and the nut of fixation clip.
Described base is provided with locating pad, and locating pad is positioned at all sides of tapering mandrel and is fixed on the base by slotted countersunk flat head screw.
The utility model has the following advantages compared to existing technology:
The tapering mandrel outer wall that the utility model adopts and the inwall of elastic expansion sleeve all have tapering, when elastic expansion sleeve is subject to downward pressure, the external diameter of elastic expansion sleeve can support greatly, thereby the outer wall of elastic expansion sleeve and the endoporus of workpiece are fitted tightly, in order to eliminate on the workpiece for the endoporus of location and the gap between the frock, thereby the reduction systematic error has been guaranteed the axiality requirement of workpiece 0.05 when improving the product processing progress.
Simple in structure, the easy to operate and accurate positioning of positioning tool of the present utility model has reduced the fraction defective of product, suitable promoting the use of when having improved Product Precision and quality.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is use view of the present utility model.
Wherein: 1-base; 2-tapering mandrel; 3-screwed hole; 4-elastic expansion sleeve; 5-bolt; 6-regulate and support; 7-stud; 8-pressing plate; 9-packing ring; 10-nut; 11-locating pad; 12-slotted countersunk flat head screw; 13-workpiece.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Shown in Fig. 1-2: a kind of horizontal lathe positioning tool, comprise base 1, be provided with the tapering mandrel 2 that is fixedly installed at the middle part of base 1, the middle part of tapering mandrel 2 is provided with the screwed hole 3 of opening upwards, be covered with elastic expansion sleeve 4 on the tapering mandrel 2, elastic expansion sleeve 4 is fixedly linked by bolt 5 and the tapering mandrel 2 that is complementary with screwed hole 3, and the inwall of elastic expansion sleeve 4 is provided with the conical surface that the outer wall with tapering mandrel 2 is complementary.Be provided with the adjusting that axle is evenly distributed on the base 1 centered by tapering mandrel 2 at base 1 in addition and support 6, the inboard of regulating supporting 6 is provided with the stud corresponding with it 7, the lower end of stud 7 is fixedly installed on the base 1, the top of stud 7 is provided with an end and is positioned at the pressing plate 8 of regulating supporting 6 tops, the other end of pressing plate 8 is used for fixing workpiece 13, and the top of stud 7 is provided with packing ring 9 and the nut 10 of fixation clip 8; Also be provided with simultaneously the locating pad 11 for location workpiece 13 on base 1, locating pad 11 is positioned at all sides of tapering mandrel 2 and is fixed on the base 1 by slotted countersunk flat head screw 12.
Use state of the present utility model as shown in Figure 2, at first with pressing plate 8 removal from the stud 7, then workpiece 13 is nested with on the outer wall of elastic expansion sleeve 4, the bottom surface of workpiece 13 is dropped on the locating pad 11, regulate the height of supporting 6 according to the Height Adjustment of workpiece 13 locating surfaces, then pressing plate 8 is installed in the position that also locks pressing plates 8 with packing ring 9 and nut 10 on the stud 7 and fixes workpiece 13; Adjust at last the bolt 5 on the elastic expansion sleeve 4, so that the external diameter of elastic expansion sleeve 4 becomes large, thereby the outer wall of elastic expansion sleeve 4 and the endoporus of workpiece 13 are fitted tightly, in order to eliminate on the workpiece 13 for the endoporus of location and the gap between the frock, thereby the reduction systematic error has guaranteed that the axiality of workpiece 13 reaches in 0.05 when improving the product processing progress.
