Abstract
The utility model relates to a metal plate punching limiting tool, which is characterized by comprising a substrate, wherein the substrate is provided with two limiting parts; the same sides of the two limiting parts are provided with a limiting plane A and a limiting plane B respectively; the limiting plane A is vertical to the limiting plane B; and the substrate is hinged with a limiting rotary block through a hinge shaft. The metal plate punching limiting tool has the advantages of simple structure, convenience in use, capability of increasing the processing accuracy and high positioning speed.
Description
Technical field
The utility model belongs to the positioning tool technical field, particularly relates to a kind of for metallic plate punching limiting tool.
Background technology
Generally need in the machine-building process to use positioning fixture, positioning fixture is used for fixing processing object, makes it to occupy correct position, to accept processing or to detect.At present, before machining hole on the metallic plate, need to carry out spacing to metallic plate, in the conventional art, utilize after anchor clamps are fixedly clamped rectangular metal plate, punching on metallic plate, the hole that punching press is different, need to adjust manually clamping angle and the position of metallic plate, in the adjustment process, with the different sides of rectangular metal plate as positioning datum, rectangular metal plate side mismachining tolerance can affect drilling precision, and utilizing the clamp metallic plate is a loaded down with trivial details process, and metallic plate conversion position location need to spend long time, and working (machining) efficiency is low.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to use, can improve machining accuracy, the fast metallic plate punching limiting tool of locating speed.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of metallic plate punching limiting tool, it is characterized in that: comprise substrate, described substrate is provided with two limiting sections, have respectively spacing plane A and spacing plane B on the same side of described two limiting sections, described spacing plane A is mutually vertical with spacing plane B, passes through the hinged spacing switch block of hinge on the described substrate.
The utility model can also adopt following technical scheme:
The axis of the hinge of the spacing switch block of described connection is perpendicular to described spacing plane A.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, namely be provided with two limiting sections at substrate, have respectively orthogonal spacing plane A and spacing plane B on two limiting sections, pass through the hinged spacing switch block of hinge at substrate, can be all take spacing plane A as benchmark in the different hole of rectangular metal plate processing, avoided the mismachining tolerance of rectangular metal plate side that metallic plate punching precision is impacted, spacing switch block can the top laminated metal sheet, also can sink to by rotation the bottom of metallic plate, make the side top of metallic plate press spacing plane B, realized utilizing the different hole of same datum plane punching press, positioning accuracy is high, and compares conventional brace, both can carry out spacing to the different station of metallic plate by the rotary spacing switch block, convenient and swift, improved working (machining) efficiency.
Description of drawings
Fig. 1 and Fig. 2 are respectively the structural representations of two duties of the present utility model;
Fig. 3 is the top view of Fig. 1.
Among the figure: 1, substrate; 2, workbench; 3, limiting section; 4, hinge; 5, spacing switch block; 6, rectangular metal plate; 7, drift.
A, spacing plane; B, spacing plane.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1 Fig. 2 and Fig. 3, a kind of metallic plate punching limiting tool.Comprise substrate 1, substrate 1 is installed on the workbench 2 of punch press, substrate 1 is provided with two limiting sections 3, have respectively spacing plane A and spacing plane B on the same side of two limiting sections 3, spacing plane A is mutually vertical with spacing plane B, by hinge 4 hinged spacing switch blocks 5, the axis of hinge 4 is perpendicular to spacing plane A on the substrate 1.
Operation principle of the present utility model:
Need to process four hole a, b, c, d on the rectangular metal plate 6, two adjacent side of rectangular metal plate 6 are L1 and L2, and the line of centres of the line of centres of hole a, b and hole c, d has two drifts 7 perpendicular to L1 on the stamping machine.Before the metallic plate punching press, fitted in the L1 limit of rectangular metal plate 6 and the spacing plane A on the frock, the top, L2 limit of rectangular metal plate 6 is pressed on the end of spacing fragment of brick 5, and the other end of spacing fragment of brick 5 is supported on the workbench 2, drift 7 is finished punching press action, makes portal a, b; Rotary stopper fragment of brick 5, make spacing fragment of brick 5 integral body sink to the below of rectangular metal plate 6, promote rectangular metal plate 6 along spacing plane A, fit with spacing plane A all the time in the L1 limit of rectangular metal plate 6, the top, L2 limit of rectangular metal plate 6 is pressed on the spacing plane B, drift 7 is finished punching press action, makes portal c, d.
Above-mentioned embodiment only is to functional descriptions of the present utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; various distortion and improvement that those skilled in the art make the technical solution of the utility model all drop within the protection domain of the present utility model.
