Abstract
Description
Technical Field
[0001] This application relates to the field of machining, and more particularly to a positioning carrier used on a high-precision micrometer. Background Technology
[0002] An outside micrometer, also called a screw micrometer, is often simply referred to as a "micrometer". It is a more precise length measuring instrument than a vernier caliper, with accuracies of 0.01mm, 0.02mm, and 0.05mm. Including the estimated reading of 1 decimal place, it can be read to 3 decimal places (thousandths), hence the name micrometer.
[0003] An outside micrometer consists of a fixed frame, an anvil, a micrometer screw, a fixed sleeve, a micrometer drum, a force measuring device, and a locking device. When measuring the outside diameter of a product, the anvil and micrometer screw rest against the outside of the product to measure its diameter.
[0004] like Figure 8 As shown in the image, the product is a fingerprint recognition button used in a tablet computer. When measuring its outer diameter with a micrometer, the operator needs to squeeze the fingerprint recognition button to the appropriate position before using the micrometer. However, because the fingerprint recognition component has a hollow center and thin side walls, it is difficult to control the squeezing force when measuring by hand, which can lead to product deformation. Furthermore, the measurement position of the product is not easily parallel to the micrometer screw, which will increase the measurement error. In addition, during measurement, it is difficult for the operator to control the force of rotating the micrometer. The micrometer screw may squeeze the product and deform it as it gets closer to the anvil, ultimately resulting in inaccurate product dimensions. Summary of the Invention
[0005] The purpose of this application is to propose a positioning carrier for use on high-precision micrometers, so as to solve the problem that product deformation and measurement inaccuracy occur when using micrometers to measure products in the prior art.
[0006] A positioning carrier for use on a high-precision micrometer includes a clamping fixture, a positioning bracket, and a probe; the clamping fixture can abut against the inside of the product and clamp the product, the positioning bracket can be snapped onto the clamping fixture, and the probe can be snapped onto the positioning bracket.
[0007] The probe includes a first contact and a second contact. One end of the first contact can contact the anvil of the micrometer, and the other end of the first contact can contact the outside of the product. One end of the second contact can contact the micrometer screw of the micrometer, and the other end of the second contact can contact the outside of the product. The first contact can cooperate with the second contact to abut against the outside of the product.
[0008] Its beneficial effects are as follows: This positioning carrier replaces the method of positioning the product by the measuring personnel, reducing the interference of the measuring personnel on the measurement accuracy and preventing product deformation caused by manual intervention; the clamping fixture can abut against the inside of the product and clamp the product, providing effective support for the product from the inside out, preventing the problem of the micrometer screw constantly moving closer to the anvil during measurement and squeezing the product and deforming it; the setting of the probe ensures that the position of the product is always parallel to the micrometer screw, improving the measurement accuracy, and ultimately improving the product yield and enhancing the product's market competitiveness.
[0009] In some embodiments, the clamping fixture includes
[0010] A positioning block, which has a through hole;
[0011] A pull rod that can pass through a through hole and move within the through hole;
[0012] The elastic element is sleeved on the tie rod;
[0013] The clamping block is fixedly connected to the pull rod and located on one side of the positioning block. The clamping block can move towards or away from the positioning block under the action of the pull rod. The clamping block can abut against the inside of the product and clamp the product.
[0014] Its beneficial effects are: the measuring personnel can push the bottom of the pull rod, so that the clamping block moves with the pull rod, and a space that can accommodate the product is formed between the clamping block and the positioning block. After the product is fixed on the clamping block, the measuring personnel stop pushing the pull rod. Under the action of the elastic element, the pull rod returns to its original position, and the pull rod drives the clamping block to return to its original position, and finally the product is fixed on the positioning block by the clamping block.
[0015] In some embodiments, the clamping block is provided with a clamping part, the shape of which can match the inner shape of the product.
[0016] Its beneficial effect is that the clamping part can tightly abut against and support the product from the inside to fix the product and prevent the product from shifting.
[0017] In some embodiments, the positioning bracket has a hollow center and a groove is provided on the inner side of the positioning bracket.
[0018] In some implementations, the positioning block is provided with protrusions that match the groove.
[0019] Its beneficial effects are: the cooperation between the groove and the protrusion facilitates the assembly and disassembly of the positioning bracket and the positioning block.
[0020] In some embodiments, the positioning bracket is further provided with a locking part, and a gap is provided between the locking part and the positioning bracket to accommodate the probe.
[0021] Its beneficial effect is that the gap setting facilitates the disassembly and assembly of the probe.
[0022] In some embodiments, the engaging portion is provided with an inclined surface that can contact the probe, and the inclined surface is used to guide the probe.
[0023] In some implementations, the positioning block is also provided with a boss, on which the product can be placed and held by the clamping block.
[0024] In some implementations, both the first contact and the second contact include
[0025] The contact tip can contact the anvil or micrometer screw of the micrometer;
[0026] The snap-fit terminal connects to the other end of the contact terminal;
[0027] The fixing end is connected to the snap-fit end and can abut against the outside of the product to fix the product in place.
[0028] Its beneficial effects are: the contact end needs to be in direct contact with the anvil or micrometer screw, so sufficient contact strength is required; the snap-fit end facilitates the disassembly of the probe within the gap; and the fixed end will directly contact the outside of the product.

For example, they can refer to a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0043] A positioning carrier for use on a high-precision micrometer includes a clamping fixture 1, a positioning bracket 2, and a probe 3; the clamping fixture 1 can abut against the inside of the product and clamp the product, the positioning bracket 2 can be snapped onto the clamping fixture 1, and the probe 3 can be snapped onto the positioning bracket 2.
[0044] The probe 3 includes a first contact 31 and a second contact 32. One end of the first contact 31 can contact the anvil of the micrometer, and the other end of the first contact 31 can contact the outside of the product.

[0045] When measuring the outer diameter of a product, the product is fixed on the clamping fixture 1. The clamping fixture 1 can fix the product by "internal support". At this time, the measuring personnel then place the micrometer's anvil against the first contact 31. At the same time, the first contact 31 is also against one end of the outer side of the product. The micrometer's micrometer screw is adjusted to move closer to the anvil to contact the second contact 32 until the second contact 32 is against the other end of the outer side of the product. After completing the above steps, the outer diameter of the product is finally measured.

After the product is fixed on the clamping block 14, the measuring personnel stop pushing the pull rod 12. Under the action of the elastic element 13, the pull rod 12 resets, and the pull rod 12 drives the clamping block 14 to reset, and finally the product is fixed on the positioning block 11 by the clamping block 14.
