Description

Technical Field

[0001] This utility model belongs to the field of probe tooling technology, and more specifically, it relates to a positioning and calibration tooling for a multi-layer composite structure probe. Background Technology

[0002] The positioning and calibration fixture for multi-layer composite probes is used to ensure that the probe is accurately aligned with the target position during testing or processing, thereby improving measurement stability and repeatability.

[0003] When the tooling is used to position the probe, different positioning components need to be replaced because the probe has different operating specifications. However, the commonly used positioning and calibration tooling requires tools to replace the positioning and calibration components, which reduces the convenience of tooling replacement. Utility Model Content

[0004] This disclosure relates to a positioning and calibration fixture for a multi-layer composite structure probe, in order to solve the problem mentioned in the background art that, since probes have different operating specifications, different positioning components need to be replaced in the fixture to perform positioning operations on the probes. However, commonly used positioning and calibration fixtures require tools or other means to replace the positioning and calibration components, which leads to a decrease in the convenience of fixture replacement.

[0005] The positioning and calibration fixture for a multi-layered composite structure probe of this utility model is achieved by the following specific technical means: This utility model provides a positioning and calibration fixture for a multi-layered composite structure probe, comprising: a fixture base, wherein two fixture seats slide symmetrically on the top of the fixture base; a positioning block is installed on one side of the fixture seats; the fixture base further comprises: two limiting joints, which are symmetrically and integrally disposed on the top of the fixture base; a limiting rod, which is fixedly installed between the limiting joints; four fixed base frames, which are symmetrically and fixedly installed at the bottom of the fixture base; and two positioning cylinders, which are symmetrically and fixedly installed inside the fixture base; one end of the piston rod of the positioning cylinder is fixedly connected to the middle of one side of the fixture seat.

[0006] As a preferred embodiment of this utility model, the tooling base further includes: a limiting head, which is fixedly installed in the middle of the top of the tooling base; the limiting head and the limiting rod are slidably connected; an installation groove, which is opened on one side of the tooling base; a positioning block is installed inside the installation groove; and two limiting grooves, which are symmetrically opened on the inner side of the installation groove.

[0007] As a preferred embodiment of this utility model, the tooling base further includes: a fixed shell, which is fixedly installed at the rear end of the tooling base; a fixed slider, which slides inside the fixed shell; and two fixed inserts, which are symmetrically and integrally disposed on one side of the fixed slider.

[0008] As a preferred embodiment of this utility model, the tooling base further includes: a mating block, which is integrally disposed in the middle of one side of the fixed slider; a fixing screw, which rotates on the other side of the fixed slider; and a threaded connection between the fixing screw and the fixed shell.

[0009] As a preferred embodiment of this utility model, a positioning groove is provided on one side of the positioning block; the positioning block also includes: a limiting strip, the number of limiting strips is set to two, the limiting strips are symmetrically and integrally set at the upper and lower ends of the positioning block; the limiting strips match the limiting groove; and a fixing block, the fixing block is fixedly installed at the rear end of the positioning block.

[0010] As a preferred embodiment of this utility model, the positioning block further includes: a reinforcing slot, the number of which is set to two, the reinforcing slots being symmetrically opened on one side of the fixing block at the top and bottom; a fixing slot, the fixing slot being opened in the middle of one side of the fixing block; the fixing slot matching the mating insert; and the reinforcing slot matching the fixing insert.

[0011] Compared with the prior art, the present invention has the following beneficial effects: When clamping and positioning probes of different specifications, the operator only needs to rotate the fixing screw, which will drive the fixing slider to move smoothly along the guide structure through the threaded transmission. This allows the mating block on one side of the fixing slider to exit precisely from the fixing slot and the reinforcing slot simultaneously with the fixing block, thereby quickly releasing the fixing constraint on the positioning block. At this time, the original positioning block can be easily removed and replaced with a positioning block that is compatible with the new probe specifications.

[0012] When installing a new positioning block, simply insert the positioning block's limiting strip smoothly along the precision guide rail of the limiting groove, ensuring that the fixing block accurately abuts against the positioning end face of the fixing shell. Then, rotate the fixing screw in the opposite direction to drive the mating insert and the fixing insert to re-insert into the mating gap between the fixing slot and the reinforcing slot. The interference fit of the insertion structure generates a self-locking effect, which not only enables the quick replacement and reliable fixing of the positioning block, but also effectively suppresses vibration displacement during the testing process. At the same time, the conical surface fit design of the insert and the slot can compensate for machining tolerances and enhance torsional stiffness. The guiding structure of the limiting strip and the limiting groove ensures the centering accuracy during the replacement process. Ultimately, the tooling can adapt to the positioning requirements of probes with different diameters and different coating structures, greatly improving the work efficiency of multi-variety, small-batch testing tasks.

[0021] The fixture base 2 further includes: a limiting head 201, which is fixedly installed in the middle of the top of the fixture base 2; the limiting head 201 is slidably connected to the limiting rod 102; a mounting groove 202, which is opened on one side of the fixture base 2; a positioning block 3 installed inside the mounting groove 202; two limiting grooves 203, which are symmetrically opened inside the mounting groove 202; and a fixing shell 204, which is fixedly installed on the fixture base 2. The rear end includes: a fixed slider 205 that slides inside a fixed housing 204; two fixed inserts 206 that are symmetrically and integrally disposed on one side of the fixed slider 205; a mating insert 207 that is integrally disposed in the middle of one side of the fixed slider 205; and a fixed screw 208 that rotates on the other side of the fixed slider 205. The fixed screw 208 is threadedly connected to the fixed housing 204.

[0022] The positioning block 3 has a positioning groove on one side; the positioning block 3 also includes: a limiting strip 301, the number of which is set to two, the limiting strips 301 are symmetrically and integrally set at the upper and lower ends of the positioning block 3; the limiting strips 301 match the limiting groove 203; a fixing block 302, the fixing block 302 is fixedly installed at the rear end of the positioning block 3; a reinforcing slot 303, the number of which is set to two, the reinforcing slots 303 are symmetrically opened on the upper and lower sides of one side of the fixing block 302; a fixing slot 304, the fixing slot 304 is opened in the middle of one side of the fixing block 302; the fixing slot 304 matches the mating plug 207; the reinforcing slot 303 matches the fixing plug 206.

[0023] The specific usage and function of this embodiment: When the tooling fixes and positions the probe, the probe is placed between the positioning blocks 3, and then the positioning cylinder 104 is activated. The positioning cylinder 104 will drive the tooling seat 2 to slide, and the positioning block 3 on one side of the tooling seat 2 can clamp and position the probe so that the probe can be used in subsequent applications.

[0024] When clamping and positioning probes of different specifications, the fixing screw 208 can be rotated, which will drive the fixing slider 205 to move. The mating block 207 and fixing block 206 on one side of the fixing slider 205 will disengage from the fixing slot 304 and the reinforcing slot 303, respectively.
