Abstract
A self-locking fixing device comprises an upper frame and a lower base, wherein a fixing plate is vertically arranged between the upper frame and the lower base, a sliding groove is formed in the middle of the fixing plate, the sliding plate is mutually connected with the fixing plate in a sliding mode through the sliding groove, and a longitudinal spring is vertically arranged on the lower bottom surface of the upper frame and is mutually connected with the sliding plate; this application passes upper frame and sliding plate surface in required spacing firm work piece and contacts each other to continuously push down, make the stopper extrude horizontal spring and contract automatically, treat that the work piece pushes down highly be less than when the stopper, the stopper just carries out high spacing through horizontal spring auto-eject to the work piece.
Description
Technical Field
The utility model relates to the technical field of tools, in particular to a self-locking fixing device.
Background
Generally, when a workpiece is processed, a fixing jig is needed to fix the workpiece, so that the workpiece quality is prevented from being affected by deviation generated in the processing production process, and for some workpieces with precision requirements, not only the whole workpiece needs to be fixed, but also the processing precision needs to be ensured, so that the precision requirements are met, and the product quality is prevented from being affected.
Disclosure of Invention
In order to solve the above problems, the present invention provides a self-locking fixing device.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a self-locking fixing device, includes upper frame and lower base, its characterized in that: the upper frame is characterized in that a fixed plate is vertically arranged between the upper frame and the lower base, a sliding groove is formed in the middle of the fixed plate, the sliding plate is in sliding connection with the fixed plate through the sliding groove, the upper frame is of a hollow structure and is provided with a transverse spring, the whole limiting block is of a trapezoidal structure and penetrates through the inner side surface of the upper frame to be connected with the transverse spring, and a longitudinal spring is vertically arranged on the lower bottom surface of the upper frame and is connected with the sliding plate.
Furthermore, the outer side surfaces of the upper frame and the lower base are arc-shaped or rectangular structures.
Furthermore, 4-6 fixing plates are vertically arranged between the upper frame and the lower base.
Furthermore, 1-2 transverse springs are arranged inside the upper frame.
Furthermore, 1-2 longitudinal springs are vertically arranged on the lower bottom surface of the upper frame.
The utility model has the beneficial effects that: this application passes frame and sliding plate surface in required spacing firm work piece and contacts each other, and continuously push down, because the stopper is whole to be the trapezoidal body structure, can laminate its tangent plane and push down when the work piece pushes down, make stopper extrusion transverse spring shrink automatically, treat that the work piece pushes down highly be less than when the stopper, the stopper just pops out through transverse spring auto-eject, it is highly spacing to carry out the work piece, meanwhile longitudinal spring makes the further firm effect of playing the work piece of sliding plate shrink, the improvement product quality has been reached, guarantee the beneficial effect of operation precision.

Reference numerals: the device comprises a lower base 1, a fixed plate 2, an upper frame 3, a sliding groove 21, a sliding plate 22, a longitudinal spring 23, a transverse spring 31 and a limiting block 32.
Detailed Description
In order to make the technical solution of the present invention more apparent, the present invention is further described with reference to the following embodiments.
As shown in fig. 1 to 3, a self-locking fixing device according to an embodiment of the present invention includes an upper frame 3 and a lower base 1, and is characterized in that: the upper frame 3 is vertically provided with a fixed plate 2 between the lower base 1, the middle part of the fixed plate 2 is provided with a sliding groove 21, the sliding plate 22 is connected with the fixed plate 2 through the sliding groove 21 in a sliding manner, the inside of the upper frame 3 is of a hollow structure and is provided with a transverse spring 31, the whole limiting block 32 is of a trapezoidal structure and penetrates through the inner side surface of the upper frame 3 to be connected with the transverse spring 31, and the lower bottom surface of the upper frame 3 is vertically provided with a longitudinal spring 23 and is connected with the sliding plate 22.
Further, the outer side surfaces of the upper frame 3 and the lower base 1 are arc-shaped or rectangular structures.
Furthermore, 4-6 fixing plates 2 are vertically arranged between the upper frame 3 and the lower base 1.
Further, 1-2 transverse springs 31 are arranged inside the upper frame 3.
Further, 1-2 longitudinal springs 23 are vertically arranged on the lower bottom surface of the upper frame 3.
As shown in fig. 1-3, when the application is needed to limit and stabilize a workpiece, the workpiece to be limited and stabilized is firstly passed through the upper frame 3 and contacted with the surface of the sliding plate 22, and is continuously pressed downwards, because the whole limiting block 32 is of a trapezoidal structure, the workpiece can be attached to the tangent plane and pressed downwards when pressed downwards, the limiting block 32 is enabled to extrude the transverse spring 31 to automatically contract, when the workpiece is pressed downwards to a height lower than the limiting block 32, the limiting block 32 is automatically popped out through the transverse spring 31 to limit the height of the workpiece, then the workpiece is stopped to be pressed downwards, the longitudinal spring 23 is enabled to drive the sliding plate 22 to rebound and contract, the workpiece is further driven to act on the lower bottom surface of the limiting block 32, the workpiece is stabilized by the mode, the beneficial effects of improving the product quality and ensuring the operation precision are achieved.
The above embodiments may be combined with each other and further implemented without being mutually opposed.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
