Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a gauge with switchable reference blocks. Background Technology

[0002] The reference blocks on the fixture are designed based on theoretical part data. However, during the development process, the actual part may not be consistent with the theoretical data. The part may be twisted or have other surface changes. At this time, the position of the part surface change will come into contact with a reference block, which will cause other reference blocks to be off-center. It is impossible to clearly determine whether the off-center position of a certain reference block is due to the part being actually off-center or due to the part being deformed and the part surface interfering with the reference block. If the reference blocks are pressed tightly, the part will deform, and the measured data will be distorted with a large error, affecting the judgment of the part size. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1 and Figure 2 , Figure 1 A perspective view of the gauge with switchable reference blocks provided in an embodiment of this utility model. Figure 2 An exploded view of the gauge with switchable reference blocks provided in an embodiment of this utility model.

[0037] This utility model discloses a gauge with a switchable reference block, which includes a support base 1, a connecting rod 2, an adjustment mechanism 4, and a locking mechanism 5.

[0038] The support base 1 can be made of a material with certain strength, not easily deformed and not easily corroded, such as aluminum alloy or stainless steel. The support base 1 is provided with an assembly hole. The cross-section of the assembly hole includes, but is not limited to, a circle or a polygon. The first end of the connecting rod 2 is reciprocally moved in the assembly hole. The second end of the connecting rod 2 extends out of the assembly hole and is detachably connected to the reference block 3. The adjusting mechanism 4 is connected to the connecting rod 2 to adjust the length of the second end of the connecting rod 2 extending out of the assembly hole. The locking mechanism 5 is used to lock the connecting rod 2 relative to the support base 1.

[0039] The support base 1 can be equipped with a set of connecting rods 2, adjusting mechanism 4 and locking mechanism 5, or multiple sets of connecting rods 2, adjusting mechanism 4 and locking mechanism 5. When multiple sets of connecting rods 2, adjusting mechanism 4 and locking mechanism 5 are provided on the support base 1, the relative positions of each set of connecting rods 2, adjusting mechanism 4 and locking mechanism 5 are designed according to the shape and structure of the part being inspected.

[0040] The support base 1 can be an integral structure, on which one or more structures for mounting the connecting rod 2, the adjusting mechanism 4 and the locking mechanism 5 are provided.

[0041] Of course, the support base 1 can also adopt a modular structure, that is, it is composed of multiple identical or different components. When inspecting parts, different numbers or different structures of support base 1 can be selected for assembly to adapt to the parts to be inspected.

[0042] Compared with the prior art, the reference block 3 of the switchable reference block inspection fixture provided in this application embodiment is detachably connected to the connecting rod 2, and the connecting rod 2 is also detachably mounted on the support base 1. In this way, when the reference block 3 and the connecting rod 2 are worn, replacement parts can be quickly replaced, reducing the overall replacement cost. At the same time, the position of the reference block 3 can be adjusted and locked at any time through the adjustment mechanism 4. The height of the reference block 3 can be adjusted according to the changes of the parts, and the actual deviation data can be obtained accordingly. Data can also be measured after the product is pressed and when it is not pressed, thereby quickly detecting the true state of the parts, reducing the error caused by repeated product assembly, and providing data support for the formulation of subsequent rectification plans.

[0043] like Figures 1 to 3 As shown, in one embodiment of this application, the connecting rod 2 includes an assembly rod portion 201, an mounting rod portion 202, and an intermediate connecting portion 203.

The axial dimension of the intermediate connecting portion 203 is smaller than the axial dimension of the two side assembly rod portions 201 and the mounting rod portions 202. The assembly rod portion 201, as the first end of the connecting rod 2, is reciprocally disposed within the assembly hole. The mounting rod portion 202 is connected to the assembly rod portion 201. The end of the mounting rod portion 202 away from the assembly rod portion 201 is detachably connected to the reference block 3. The mounting rod portion 202 is connected to the assembly rod portion 201 through the intermediate connecting portion 203. The surface of the intermediate connecting portion 203 facing the mounting rod portion 202 is a detection surface 2a.

[0044] For further optimization of the above technical solution, please refer to [link / reference]. Figures 1 to 3In one embodiment of this application, the assembly rod 201 is provided with a length scale mark 2b. In application, when the extension amount of the connecting rod 2 is adjusted by the adjustment mechanism 4, the extension amount of the connecting rod 2 in that state can be directly obtained from the length scale mark 2b. Thus, the actual deviation data can be obtained directly from the reading on the length scale mark 2b during measurement.

[0045] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the adjusting mechanism 4 includes an elastic element 401 and an adjusting bolt 402.

The adjusting bolt 402 is threadedly engaged with the connecting rod 2. The adjusting bolt 402 can move helically relative to the connecting rod 2 to adjust the preload of the elastic element 401.

[0046] Preferably, such as Figure 1 As shown, the elastic element 401 is a compression spring, which is sleeved on the outside of the adjusting bolt 402.

[0048] like Figure 1 , Figure 2 and Figure 4 As shown, the first support block 101 is provided with a first through hole 1a, and the second support block 102 is provided with a second through hole 1b. The second through hole 1b is a stepped hole. The large ends of the first through hole 1a and the second through hole 1b are connected to form an assembly hole. That is, the diameters of the large ends of the first through hole 1a and the second through hole 1b are the same and larger than the diameter of the small end of the second through hole 1b. The small end of the second through hole 1b forms an installation hole for the adjusting bolt 402 to extend into the assembly hole.

[0049] like Figure 1 and Figure 2As shown, in one embodiment of this application, the locking mechanism 5 includes a guide sleeve 501 and a locking bolt 502.

The support base 1 is provided with a locking threaded hole 1c communicating with the assembly hole. The locking bolt 502 passes through the locking threaded hole 1c on the support base 1 and is pressed against the guide sleeve 501. The locking bolt 502 is used to press the guide sleeve 501, and the locking bolt 502 can force the guide sleeve 501 to deform to clamp the connecting rod 2.

[0050] To further optimize the above technical solution, in one embodiment of this application, the guide sleeve 501 and the first end of the connecting rod 2 are anti-rotationally engaged, that is, the cross-section of the guide sleeve 501 and the connecting rod 2 is a non-circular cross-section. The cross-section of the guide sleeve 501 and the connecting rod 2 includes, but is not limited to, polygonal, waist-shaped, elliptical or irregular shapes. In the illustrated embodiment, the cross-section of the guide sleeve 501 and the connecting rod 2 is a closed shape formed by an arc curve and a straight line.

[0051] like Figure 2 As shown, in one embodiment of this application, the reference block 3 and the connecting rod 2 are connected by a fastening bolt 6. The second end face of the connecting rod 2 is provided with a fastening threaded hole 2c.
