Description
Technical Field
The utility model relates to a positioning disk with a front surface and a back surface which are tightly pressed.
Background
Some parts need compress tightly the processing other end through one end location, because of waiting to process the part location end and have the hole, and there is the installation screw hole around the hole, but do not use the step face that conventional positioning disk compressed tightly from the front, and prop the hole clamping with general three-jaw chuck, lead to the hole to warp easily, or because of the clamping degree of depth causes the machining dimension unstability inadequately even not hard up to cause the part processing unqualified, be difficult to satisfy the machining precision requirement.
Disclosure of Invention
An object of the utility model is to overcome the above-mentioned not enough and provide a positioning disk that openly installation reverse side compressed tightly, simple structure, location are accurate, the dismantlement is convenient.
The technical scheme of the utility model is that: the positioning disc comprises a circular truncated cone-shaped positioning disc body, wherein a cylinder used for being fixed on a lathe spindle chuck is arranged on the upper plane of the positioning disc body, a circular truncated cone-shaped positioning end used for being fixedly installed with a part to be machined is arranged on the lower plane of the positioning disc body, the end face of a circular ring is fixedly sleeved outside the cylinder, the end face of the circular ring divides the cylinder into a clamping end and an extension section used for facilitating screwing of a screw tool from top to bottom, and a plurality of installation through holes used for being fixedly installed with the part to be machined are symmetrically arranged on the positioning disc body; the positioning disc body, the circular ring end face, the clamping end, the positioning end and the extension section to-be-machined parts are on the same central line.
The diameter of the cylinder is D1, the diameter of positioning disc body is D2, the diameter of positioning end is D3, D2 > D3 > D1.
The distance between the two opposite mounting through holes is L, and L is larger than D3.
The outer diameter of the end face of the circular ring is 2-5 mm larger than the outer diameter of the cylinder.
The beneficial effects of the utility model reside in that: the structure is simple, the positioning is accurate, and the disassembly is convenient; the location end passes through the excircle and treats that the cooperation of processing part hole realizes fixing a position, passes the positioning disk mounting hole through the screw and twists and treat that the processing part realizes compressing tightly, realizes that the front installation reverse side compresses tightly, the other one end of processing part.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a top view of the present invention;
FIG. 3 is a diagram illustrating the usage status of the present invention;
in the drawing, the positioning disc comprises a positioning disc body 1, a part to be machined 2, a circular ring end face 3, a clamping end 4, a positioning end 5, a mounting through hole 6, a mounting through hole 7 and an extension section.
Detailed Description
In fig. 1, the utility model discloses a positioning disk body 1 of round platform shape, the plane is equipped with the cylinder that is used for fixing on the lathe spindle chuck on positioning disk body 1, the lower plane is equipped with the location end 5 that is used for and waits to process 2 fixed mounting's round platform shape of part. The circular ring end face 3 is fixedly sleeved outside the cylinder. The circular ring end surface 3 divides the cylinder into a clamping end 4 and an extension section 7 for facilitating the screwing tool from top to bottom. A plurality of mounting through holes 6 used for being fixedly mounted with the part 2 to be processed are symmetrically arranged on the positioning disc body 1. The positioning disc body 1, the circular ring end face 3, the clamping end 4, the positioning end 5 and the extension section 7 are positioned on the same central line of the part 2 to be processed. The diameter of the cylinder is D1, the diameter of the positioning disc body 1 is D2, the diameter of the positioning end 5 is D3, and D2 is more than D3 and more than D1. The distance between two opposite mounting through holes 6 is L, L > D3. The utility model has simple structure, accurate positioning and convenient disassembly; the location end passes through the excircle and treats that the cooperation of processing part hole realizes fixing a position, passes the positioning disk mounting hole through the screw and twists and treat that the processing part realizes compressing tightly, realizes that the front installation reverse side compresses tightly, the other one end of processing part.
In fig. 2, 4 mounting through holes 6 for fixing and mounting the part 2 to be processed are symmetrically arranged on the positioning plate body 1. The positioning disc body 1, the circular ring end face 3, the clamping end 4, the positioning end 5 and the extension section 7 are positioned on the same central line of the part 2 to be processed. The outer diameter of the circular ring end face 3 is 2-5 mm larger than the outer diameter of the cylinder.
In fig. 3, the utility model discloses a clamping end 4 is fixed on horizontal lathe spindle chuck. The clamping end 4 is clamped by the horizontal lathe spindle chuck, the end face of a clamping jaw of the horizontal lathe spindle chuck is flatly attached to the circular ring end face 3 between the clamping end 4 and the extension section, and the axis of the positioning disc body 1 is guaranteed to be concentric with the rotating axis of the lathe chuck. The part 2 to be processed is attached to the outer circle of the positioning end 5 through an inner hole of the part 2 to be processed, and the part 2 to be processed is locked through the back face by using a screwdriver or an internal hexagonal wrench handle screw. The positioning end 5 is in clearance fit with the part to be processed 2, and the clearance is smaller than 0.01, so that the processing precision is ensured. The rotatory drive of horizontal lathe's main shaft the utility model discloses rotatory, and then drive and treat that processing part 2 is rotatory, realize treating the processing of the other one end of processing part 2.
