Description
Technical Field
The utility model belongs to the technical field of machining, and particularly relates to a fixture for fixing a base of a position marker.
Background
The position marker is a core device of the aircraft guide head, and has the main functions of providing angular coordinate information in the motion process for the aircraft, generating corresponding guidance signals and adjusting the flight direction of an aircraft system, thereby realizing the functions of capturing and tracking targets and the like. The sensor of the coordinator is mounted on the coordinator base. The base structure of the marker shown in fig. 1 and 2 comprises a cylinder mounting frame 101, wherein a window 102 is formed around the upper part of the cylinder mounting frame 101, and a transverse positioning plate 103 is arranged on the inner ring of the cylinder mounting frame 102 close to the lower part. The transverse positioning plate 103 is provided with a pair of rectangular holes 104 and a pair of through holes 105, and the bottom inner ring of the cylinder mounting frame 102 is provided with a circle of mounting grooves 106.
After the base of the positioner is molded, a workpiece is required to be transversely or vertically fixed on a processing turntable, then the workpiece is driven to rotate, and the workpiece is subjected to operations such as deburring, polishing and the like through a processing machine tool. Because the whole member cylinder structure of the position marker base, the conventional fixing mode is to clamp the bottom of the workpiece by using three-jaw pneumatic grippers, but the workpiece has a certain height, and the clamping force of the three-jaw pneumatic grippers is large, so that the bottom of the workpiece is easy to deform in the processing process.
Disclosure of Invention
In view of the above problems, an objective of the present utility model is to provide a fixture for fixing a marker base, which aims to solve the above technical problems.
The utility model adopts the following technical scheme:
the fixture comprises a center cylinder, a coaxial flower head is arranged at the head end of the center cylinder, a plurality of protruding blocks are arranged on the periphery of the flower head in a circle, a pair of guide limiting blocks and a pair of threaded holes are arranged on the end face of the flower head, the fixture further comprises a circular chuck, a pair of long screws penetrate through the circular chuck, the tail ends of the long screws are threaded sections, and the long screws are used for being screwed into the threaded holes.
Further, the outer side face of the guide limiting block is locked with a side block through a bolt, and the width of the side block is matched with the width of a window, located near the side block, of the position marker base.
Further, arc chamfers are arranged at two ends of the top of the guide limiting block.
The beneficial effects of the utility model are as follows: in this structure, through design and the flower head of the adaptation of locator base bottom, and have a pair of guide stopper on the flower head, further can be spacing avoid work piece course of working to rotate to make full use of two through-holes that work piece itself inside had, set up two screw holes on the flower head, push down the work piece with circular chuck, and pass the through-hole with long screw rod and screw in to the screw hole, realize fixing work piece and frock, this structural design is reasonable, the structural feature of work piece itself has been fully utilized, the installation is fixed firm, the work piece is difficult for deformation.

Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
In order to illustrate the technical scheme of the utility model, the following description is made by specific examples.
As shown in fig. 3, the fixture for fixing the marker base provided by the embodiment comprises a central cylinder 1, a coaxial flower head 2 is arranged at the head end of the central cylinder 1, a plurality of protruding blocks 3 are arranged on the periphery of the flower head 2, a pair of guide limiting blocks 4 and a pair of threaded holes 5 are arranged on the end face of the flower head 2, the fixture further comprises a circular chuck 6, a pair of long screws 7 penetrate through the circular chuck 6, the tail ends of the long screws 7 are threaded sections, and the long screws 7 are used for being screwed into the threaded holes 5.
When the tool is used, the bottom of the workpiece is aligned with the flower head, the convex blocks on the periphery of the flower head are embedded into the groove on the bottom of the workpiece, the guide limiting block just penetrates through the rectangular hole of the workpiece to form limiting, and the two ends of the top of the guide limiting block are provided with arc chamfers so as to penetrate. Then the round chuck covers the top of the workpiece by using the round chuck, two long screws penetrate through the round chuck, the direction of the round chuck is adjusted, the two long screws can penetrate through the through holes of the workpiece and are screwed into the threaded holes on the flower head, and finally the long screws are screwed up to fix the workpiece. And then, the central cylinder is arranged on a chuck of the processing equipment. This mounting means, through design and the flower head of marker base bottom adaptation, and have a pair of guide stopper on the flower head, further can spacing avoid work piece course of working to rotate, and make full use of two through-holes that work piece itself inside had, set up two screw holes on the flower head, push down the work piece with circular chuck, and pass the through-hole with long screw rod and screw in to the screw hole, realize fixing work piece and frock, this structural design is reasonable, the structural feature of work piece itself has been fully utilized, the installation is fixed firm, the work piece is difficult for deformation.
As a preferable structure, the outer side surface of the guide limiting block 4 is locked with a side block 8 through a bolt, and the width of the side block 8 is matched with the width of a window, which is positioned near the side block, of the position marker base. In the structure, the two side blocks 8 have the functions, firstly, after the side blocks are installed, the side blocks can be just clamped on the window, and the surface workpieces can be further limited to rotate relatively; in addition, the outermost end of the edge block is positioned in the window, and even if the long screw rod is loose, the edge block can press the limiting workpiece to a certain extent, so that the workpiece is prevented from being separated from the flower head, and the safety is ensured.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
