The application embodiments, provides a kind of curvature measuring device, can be used for detecting curved surface backboard, curved surface frame, The various curved-surface structures such as curved surface membrane material, can be used for detecting entire curved die group and other any can form curved form The component of state, be applicable in detection field will not enumerate herein, be illustrated so that curved surface backboard is part to be measured as an example below.

As shown in Figure 1 and Figure 2, the curvature measuring device of the application embodiment includes mounting base 1, and mounting base 1 is for fixing Positioning beam 2 and part to be measured 3 are oppositely arranged positioning beam 2 and part to be measured 3 in a first direction.Through-hole 21 is provided in positioning beam 2, Linear measure longimetry bar 4 can be through setting in through-hole 21, and can move in through-hole 21 along first direction.Linear measure longimetry bar 4 Including first end and second end, first end with 3 concave surface of part to be measured for contacting；Scale is additionally provided on linear measure longimetry bar 4.

When detecting curvature using the detection device, positioning beam 2 and part to be measured 3 are installed in mounting base 1, positioning beam is made 2 and part to be measured 3 be oppositely arranged in a first direction, then by linear measure longimetry bar 4 through be arranged in through-hole 21, along first direction move Dynamic linear measure longimetry bar 4, contacts the first end of linear measure longimetry bar 4 and the concave surface of part 3 to be measured, by reading on linear measure longimetry bar 4 The available contact point of reading action, and then calculate the curvature of the position.

The curvature measuring structure is simple, is easily installed, convenient reading and test result is accurate, can also be set as needed The quantity of test point and position, convenient for obtaining more comprehensively accurate result.

The curvature measuring device of the application embodiment is described in detail below:

In one embodiment, as shown in figure 3, positioning beam 2 and part to be measured 3 can be installed on two peaces being oppositely arranged It fills on seat 1, each mounting base 1 is ladder-like, including the first supporting surface 11 and the second supporting surface 12, and the first supporting surface 11 is higher than the Two supporting surfaces 12, two the first supporting surfaces 11 are located at same level, for installing positioning beam 2, two the second supporting surfaces 12 In same level, for installing part 3 to be measured, first direction is vertical direction, and part 3 to be measured can be located at immediately below positioning beam 2, Positioning beam 2 is direct rod shape, and part 3 to be measured is concave upright.Linear measure longimetry bar 4, which slidably extends through, to be arranged in through-hole 21, first end Positioned at 2 lower section of positioning beam, second end is located at 2 top of positioning beam, can slide up and down along the vertical direction.

In addition to ladder-like, mounting base 1 or other shapes, as long as can be by positioning beam 2 and part to be measured as shown in Figure 3 3 are oppositely arranged up and down in the vertical direction, and the application does not limit its specific structure.Meanwhile first end can also indicate position One end above positioning beam 2, second end indicate the one end for being located at 2 lower section of positioning beam；Similarly, the first supporting surface 11 and second The definition in support face 12 also can be interchanged.

Positioning beam 2 should be bent, for positioning to linear measure longimetry bar 4 so that all in a first direction Linear measure longimetry bar 4 all measured on same benchmark, guarantee result it is reliable.Positioning beam 2 is perpendicular to the flat of first direction Shape in face can be direct rod shape as shown in Figure 1, be also possible to curve-like or other shapes.Positioning beam 2 can be with installation First supporting surface 11 of seat 1 is installed by way of bolt connection as shown in the figure, and the application does not carry out special limit to this It is fixed.The material of positioning beam 2 can be metal, avoid gravity from influencing to generate deformation, while considering device portability, preferentially select aluminium Or magnesium alloy, with alleviator weight.

It will be appreciated by persons skilled in the art that the through-hole 21 in positioning beam 2 plays effect of contraction to linear measure longimetry bar 4, It move it can only along first direction, therefore, the axis of through-hole 21 should also extend in a first direction.

Part 3 to be measured can with the second supporting surface 12 of mounting base 1 can by positioning match part 123 as shown in Figure 3 into Row installation, the structure of positioning match part 123 can be arranged according to the case where part 3 to be measured.For example, for be provided with location hole to Part 3, such as curved surface backboard are surveyed, positioning match part 123 can be column-shaped projection as shown in Figure 4, and column-shaped projection is inserted into part 3 to be measured Location hole, realize location and installation.Positioning match part 123 may be between other structures, with part 3 to be measured in clamping, grafting Deng other mating connection modes, will not enumerate herein.Further, in order to enable mounting base 1 be suitable for it is a variety of not Isostructural part to be measured 3 is checked that the positioning match part 123 in mounting base 1 can be set to dismountable connection type, with Convenient for replacing as needed, for example, bolt as shown in the figure connection.

It as shown in figure 5, linear measure longimetry bar 4 is whole in long strip, can be arranged in through-hole 21, and run through entire through-hole 21, so that first end can be contacted with part 3 to be measured.In order to keep testing result more accurate, the song of first end Yu part 3 to be measured can be made Face contact face reduces as far as possible, so as to obtain more accurate curved surface radian situation of change.Specifically, linear measure longimetry bar 4 First end diameter be less than second end diameter, such as first end can be taper as shown in the figure, to realize point contact.It is long Scale value on degree measuring rod 4 can be gradually increased by first end to second end, it is possible thereby to convenient for calculating；It is of course also possible to It is gradually increased by second end to first end.

It should be noted that all should ensure that linear measure longimetry bar 4 has regardless of the distance between contact point and positioning beam 2 There is enough length, second end will not fall off from positioning beam 2, so that linear measure longimetry bar 4 is stablized and measure.

It will be appreciated by persons skilled in the art that through-hole 21 and linear measure longimetry bar 4 can be in clearance fit.It grows in order to prevent Degree measuring rod 4 in the horizontal direction inclination angle it is excessive cause action measurement inaccuracy, the gap of through-hole 21 and linear measure longimetry bar 4 It can not be excessive.In other embodiments, linear measure longimetry bar 4 can also artificially control the movement realized on vertical direction, for example, Mutually matched screw thread can be set in linear measure longimetry bar 4 and through-hole 21, realizes Bit andits control by screw thread rotation.

When using detection device detection as shown in Figure 1, positioning beam 2 and part to be measured 3 are installed, linear measure longimetry bar 4 is worn Into through-hole 21, linear measure longimetry bar 4 is vertically lowered under the effect of gravity, until stopping when first end touches 3 concave surface of part to be measured, this When can be read out action, and then calculate curvature.When reading, the scale of 2 upper surface director's degree measuring rod 4 of positioning beam can be read Value, can also read the scale value of upper surface director's degree measuring rod 4, be modified by calculating.In other cases, such as Fruit part 3 to be measured is raised, and linear measure longimetry bar 4 can move up together therewith, is reinstalled without removing completely.

In one embodiment, as shown in Figure 1, the quantity of positioning beam 2 is multiple, the number of through-hole 21 in each positioning beam 2 It is also multiple for measuring, and the quantity and through-hole 21 of linear measure longimetry bar 4 are consistent, and can be disposed through each through-hole 21 correspondingly It is interior.The linear measure longimetry bar 4 of multiple settings at different locations can detect the curvature of the different parts of part 3 to be measured, into And the curvature of available entire test surfaces.Positioning beam 2 and the number of through-hole 21 specifically can sizes according to part 3 to be measured, inspection Accuracy requirement is surveyed to be configured.

Further, each positioning beam 2 can equidistantly be arranged in parallel, and multiple through-holes 21 in each positioning beam 2 are along positioning beam 2 Length direction is spacedly distributed, and all linear measure longimetry bars 4 can be made to be distributed more uniform, so that contact point is more equal It is even, convenient for the curvature of acquisition 3 different parts of part to be measured more evenly.

The harder part to be measured 3 of corresponding material can be with shape when its opposite both sides is fixed between two mounting bases 1 At relatively stable curve form, convenient for accurate detection.And the to be measured part 3 relatively soft for flexible membrane material etc., it is fixed on two When between mounting base 1, since material excessively softness is easily deformed, especially at middle part, concave surface is easy to heave, and can not be formed more Regular stable curved-surface shape causes curvature measuring result inaccurate.In order to guarantee that the curvature measuring device of the application can be quasi- The curvature of relatively soft part to be measured 3 is really detected, in each positioning beam 2 in the present embodiment, the weight of each linear measure longimetry bar 4 It is gradually reduced from 2 middle position of positioning beam to two sides, intermediate linear measure longimetry bar 4 is heavier as a result, in 3 concave surface of contact measured part When heaving, can have certain gravity to the position, by this heave position push, so that entire membrane material is formed regular stabilization Curved-surface shape so that testing result is more accurate.And the membrane material at edge is since apart from mounting base 1, relatively closely, curved surface is not easy Deformation, so without pushing part 3 to be measured by linear measure longimetry bar 4.

It should be noted that linear measure longimetry bar 4 weight need meet part 3 to be measured can accurately be measured and The curved-surface shape of part 3 to be measured can be destroyed.Therefore, it can be realized by controlling its material or size.

In one embodiment, the demand may be implemented by controlling the size of each linear measure longimetry bar 4.Each support The linear measure longimetry bar 4 being located among positioning beam 2 can be made heavier, the linear measure longimetry bar 4 of two sides can make each length compared on beam The diameter of measuring rod 4 is gradually reduced from 2 middle position of positioning beam to two sides, and the length of each linear measure longimetry bar 4 can also be made by fixed Position 2 middle position of beam is gradually reduced (such as Fig. 2) to two sides, both modes can realize the control to weight.Multiple length Measuring rod 4 cooperates, and the curved surface of part 3 to be measured is made not deform.

In one embodiment, as shown in figure 5, stopper section 41, and backstop can be set in the second end of linear measure longimetry bar 4 Portion 41 is located at 2 top of positioning beam, and the maximum gauge of stopper section 41 is greater than the aperture of corresponding through-hole 21, for preventing linear measure longimetry Bar 4 is fallen down from support rod.Linear measure longimetry bar 4 can be always positioned in positioning beam 2 as a result, when carrying out installation detection, be not necessarily to It is inserted into linear measure longimetry bar 4 in through-hole 21 one by one again.Stopper section 41 can be round protrusion as shown in the figure, be also possible to other Shape.The application does not carry out particular determination to this.

In one embodiment, curvature measuring device can also include level meter (not shown).Level meter can be with It is arranged in mounting base 1, such as the first supporting surface 11 and the second supporting surface 12, guarantees the levelness of supporting surface, so that positioning beam 2 Or 3 edge of part to be measured keeps horizontal.Level meter can also be arranged in positioning beam 2, guarantee the levelness of positioning beam 2, it is ensured that long It is accurate to spend the action that measuring rod 4 is surveyed.
