Abstract
The utility model provides a combined locating pin. An inner conical pin and an outer sleeve pipe are assembled, which forms the locating pin. The working surface of the inner conical pin is a conical surface. The inner circle surface of the outer sleeve pipe is also a conical surface. The conicity of the inner circle surface is the same as the conicity of the inner conical pin. An outer circle is a cylindrical surface and is provided with a through trough along the axial direction. One end or two ends of the inner conical pin are respectively also provided with a screw rod. The combined locating pin of the utility model has the advantages of reasonable design, safety, reliability, convenient usage, low requirement of accuracy for machining a pin hole, and exact and firm localization. The utility model can bear not only radial force but also axial force. The locating pin can be conveniently assembled and disassembled. The locating pin can also be repeatedly used for a plurality of times. A machine body can not be damaged.
Description
The utility model belongs to the fastening parts of using in location, relates in particular to a kind of combined type locating stud.
At present, the locating piece in the machinery all adopts whole circular cone pillar and column type locating stud, or driving fit bolt.Adopt this mode, all compare strict machining accuracy, geometric accuracy and the roughness requirement of pin and pin-and-hole.When locating as employing circular cone pillar pin 1 as shown in Figure 1, must process the cone type pin-and-hole (seeing accompanying drawing 2) that an its corresponding diameter up and down is respectively D and d on body, the processing of this pin-and-hole is comparatively complicated, must get out shoulder hole earlier (as the d in the accompanying drawing 2

3), and then twist successively with reamer such as carse, medium and small respectively and cut.And generally all operate by hand and finish, so cut in strand and often to occur roughness in the process and do not reach requirement, the aperture distortion, hole wall produces problems such as chatter mark, process the pin-and-hole of general cylindrical pin or the screw of driving fit bolt exactly, also must equally also there be above-mentioned quality problems by fraising again after the mechanical drilling.Though a kind of elastic positioning pin is arranged, this locating stud has a groove (see the locating stud 2 in accompanying drawing 3 and 4,11 is groove among the figure) in a tubular form vertically, and its pin-and-hole does not need any finishing, can use.But the poor rigidity of this pin, behind the workpiece location, its Location accuracy changes with external force.
The purpose of this utility model is to provide a kind of accurate positioning, and is safe and reliable, reusable, and do not damage body, and its pin-and-hole need not to repair the combined type locating stud that can lay.
The utility model combined type locating stud is achieved in that this locating stud is combined by interior taper pin and outer sleeve, the working surface of interior taper pin is conical surface, and the internal circular surfaces of outer sleeve also is conical surface, and its tapering is identical with interior taper pin, cylindrical is the cylndrical surface, has a groove vertically.
The tapering of taper pin is 1 in described in the utility model: 10-1: 50; The one or both ends of taper pin have screw rod in described; End at interior taper pin or screw rod has straight groove; On described screw rod, can be with plain cushion and buckle closure.
The utility model combined type locating stud is reasonable in design, and is safe and reliable, easy to use, low to the requirement on machining accuracy of pin-and-hole, and accurate positioning, firmly can bearing radial force, can bear axial force again, is convenient to loading and unloading, also can be repeatedly used, and not damage body.This locating stud is not only applicable to the location of light-duty machinery equipment such as metallurgical heavy machinery, weaving, equally also be applicable to steel structure it
Between the location.This kind locating stud is convenient to standardization and producing in serial form, and dissemination is arranged very much.
By embodiment the utility model combined type locating stud is further described with reference to the accompanying drawings.
Accompanying drawing 1 is the structural representation of existing circular cone pillar pin.
Accompanying drawing 2 is the processing schematic representation of circular cone pillar pin pin-and-hole.
Accompanying drawing 3 is the structural representation of existing elastic positioning pin.
Accompanying drawing 4 is the plan view of accompanying drawing 3.
Accompanying drawing 5 is the utility model embodiment 1 a structural representation.
Accompanying drawing 6 is embodiment 2 a structural representation.
Accompanying drawing 7 is embodiment 3 a structural representation.
Accompanying drawing 8 is the structural representation that an end has the interior taper pin of screw rod.
Accompanying drawing 9 is embodiment 4 a structural representation.
Can see that from accompanying drawing 5 the utility model is mainly combined by interior taper pin 3 and outer sleeve 4, the working surface of interior taper pin 3 is conical surface, and the internal circular surfaces of outer sleeve 4 also is conical surface, and its tapering is identical with interior taper pin 3, the cylindrical of outer sleeve 4 is the cylndrical surface, and has a groove vertically.During use, earlier outer sleeve 4 (big mouthful up) is put into and bored good positioning hole, then interior taper pin 3 (upside down little) is inserted in the outer sleeve 4, the big end of taper pin 3 in impacting with hammer again, force the external cylindrical surface enlarged-diameter of outer sleeve 4, and change along with the actual geometric configuration of pin-and-hole, body, outer sleeve 4 and interior taper pin 3 threes that make the location produce certain elastic deformation simultaneously and moltenly are one.The tapering of the combined type locating stud of this structure is 1: 30-1: for well, be mainly used in bearing radial force between 50, but be not suitable for the big occasion of vibration.The utility model embodiment 2 and 3 has proposed a kind of combined type locating stud that mainly is applicable to bearing radial force and the big occasion of vibration, sees also accompanying drawing 6,7 and 8.The characteristics of this locating stud are that the little head end at interior taper pin 3 has screw rod 7.During use, after the taper pin 3, on screw rod 7, put bullet pad 5 and nut 6 in packing into, in hammering, screw nut 6 in the taper pin 3 big ends, make it can not come off voluntarily.This kind locating stud convenient disassembly, its tapering is 1: 10-1: for well, should decide on the size of location parent between 50.For making the location even more ideal, in case of necessity, can be inserted in a buckle closure 10 and a plain cushion 9 again in the inboard of bullet pad 5, ask for an interview accompanying drawing 7.At this moment, the osculum end of outer sleeve 4 should utilize the distortion of plain cushion 9 that it is closely contacted with body a little more than body surface.For taper pin 3 in preventing rotates with nut 6, can offer straight groove 8 (seeing accompanying drawing 6-9) in the end of interior taper pin 3 or screw rod 6, in order to place the stop instrument.The utility model embodiment 4 also has a screw rod 7 at the big end of interior taper pin 3.During use, screw the nut 6 of little head end earlier, be inserted in buckle closure 10, bullet pad 5 and nut 6 and screw on the screw rod 7 of big end again and get final product.This kind locating stud can bearing radial force, can bear axial force again, and its using effect obviously is better than driving fit bolt.
