Description

Technical Field

[0001] This invention relates to a testing device, specifically to a three-probe rapid measurement device that uses a multi-probe testing module with different types of probes mounted on a base plate to quickly measure product height data. Background Technology

[0002] Currently, most probe measurements are single-probe measurements. When the target detection requirements differ significantly, it is necessary to replace the probe or use two probe modules directly for measurement. In the process of mechanism assembly and measurement, contact measurement is a traditional and commonly used height measurement method. Compared with 3D laser measurement, contact measurement has advantages such as reliable results and less susceptibility to external interference. However, existing contact measurement methods have the following drawbacks in certain situations: When using a single probe module, changing products requires replacing the probe or the probe body simultaneously, an operation usually requiring professional personnel and is cumbersome; when using multiple probe modules, frequent switching between multiple probes and consideration of interference prevention often sacrifices some production time; in current mechanisms using a single motion module to drive two probes, the distance between the two probes is generally large, requiring a long switching time, which is unsuitable for applications with high measurement speed requirements; existing measurement structures mainly use hard blocking, requiring the probe to spend more time eliminating structural vibrations during measurement to reduce errors, thus this structure needs improvement. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a three-probe rapid measurement device that can quickly measure product height data by installing a multi-probe detection module with different types of probes on the base plate.

[0004] The technical solution adopted by this invention to solve its technical problem is: a novel dual-probe detection module, comprising a central control rotating platform, a bracket, a turntable, a first base plate, a second base plate, a third base plate, a first cylinder, a first track, a first plunger buffer, and a first hydraulic buffer. The central control rotating platform, bracket, turntable, first base plate, second base plate, and third base plate are connected sequentially, and the first cylinder, first track, first plunger buffer, and first hydraulic buffer are fixed with screws. On the left side of the turntable, the lower part of cylinder number one is connected to universal joint number one. Universal joint number one connects to left and right sliders number one. Left and right sliders number one are mounted on track number one. Probe number one base plate and probe number one top fixing plate are placed on left and right sliders number one. Probe number one is placed between the probe number one base plate and probe number one top fixing plate. Cylinder number two, left track number two, right track number two, plunger buffer number two, and hydraulic buffer number two are fixed with screws. In the center of the turntable, the lower part of cylinder number two is connected to universal joint number two. Universal joint number two connects to left and right sliders number two. Left slider number two is mounted on left rail number two, and right slider number two is mounted on right rail number two. Probe number two base plate is placed on left and right sliders. Probe number two lower fixing plate and upper fixing plate are placed on probe number two base plate. Probe number two is placed between the lower and upper fixing plates. Cylinder number three, rail number three, The No. 3 plunger buffer and the No. 3 hydraulic buffer are fixed to the right side of the turntable with screws. The lower part of the No. 3 cylinder is connected to the No. 3 universal joint. The No. 3 universal joint is connected to the No. 3 left slider and the No. 3 right slider. The No. 3 left slider and the No. 3 right slider are installed on the No. 3 left slider and the No. 3 right slider. The No. 3 probe base plate is placed on the No. 3 probe base plate. The No. 3 probe lower fixing plate and the No. 3 probe upper fixing plate are placed on the No. 3 probe lower fixing plate and the No. 3 probe upper fixing plate. The No. 3 probe is placed between the No. 3 probe lower fixing plate and the No. 3 probe upper fixing plate.

[0005] The beneficial effects of this invention are as follows: Compared with traditional probe module structures, this invention combines multiple modules into one module, and the distance between each probe is also closer, greatly shortening the switching time when switching probes for testing, thereby effectively improving production efficiency. Unlike the hard contact obstruction of traditional probe modules, this invention uses hydraulic buffers and plunger buffers to perform secondary deceleration on the slider, effectively and quickly eliminating structural vibration, thereby reducing testing time, improving testing accuracy, and also mitigating the structural deformation problem caused by hard contact impact. Each probe module in this invention uses two sets of tracks, making the slider more stable and ensuring the stability of measurement results. A universal joint connection is used between the cylinder and the slider, making the slider movement smoother and more inclusive, reducing tolerance requirements for machined parts, and also reducing assembly difficulty. This invention, while ensuring stable and reliable measurement results, can shorten testing time, thereby improving production efficiency and effectively controlling production costs.

[0017] The operation steps of a three-probe rapid measuring device according to the present invention are as follows:

[0018] The operation of module one is as follows: When using probe one, the left cylinder changes from the retracted state to the extended state. It first contacts the hydraulic buffer and decelerates, then contacts the plunger buffer and finally stops. Measurement then begins. After the measurement data is read, the cylinder changes from the extended state to the retracted state, and the detection ends when it retracts back into place. This structure effectively and quickly eliminates structural vibration through secondary deceleration, thereby reducing detection time and improving detection accuracy. It also alleviates the structural deformation problem caused by prolonged impact. Similarly, the operations of other modules are as follows: When using probe two for detection, the module moves above the target and repeats the operation steps of module one to complete the measurement of module two. Probe three operates on the same steps. In the assembly and measurement process, contact measurement is a traditional and commonly used height measurement method. Compared with 3D laser measurement, this device has advantages such as reliable results and less susceptibility to external interference. Furthermore, this device can integrate multiple probe modules in a smaller space, saving space and cost.

[0019] This invention discloses a novel dual-probe detection module. Each probe module includes a base plate, a cylinder, a slide rail, and a slider. The cylinder and slide rail are fixed to the base plate with screws. A universal joint is connected to the lower part of the cylinder, and the universal joint is connected to the probe base plate. The probe base plate and the slider are fixed with screws, and the slider and slide rail are connected. The probe is fixed to the probe base plate by an upper probe fixing plate and a lower probe fixing plate. A hydraulic buffer and a plunger buffer are fixed to the base plate with screws. The probe modules are fixed to a turntable with six positions, allowing up to six probe modules to be fixed.

[0020] This invention combines multiple modules into a single module, with each probe positioned closer together, significantly reducing switching time and thus improving production efficiency. Unlike traditional probe modules with hard contact obstruction, this invention uses hydraulic and plunger buffers for secondary deceleration of the slider, effectively and quickly eliminating structural vibration, thereby reducing detection time, improving detection accuracy, and mitigating structural deformation caused by hard contact impacts. Each probe module uses two sets of tracks, making the slider more stable and ensuring the stability of measurement results. A universal joint connects the cylinder and slider, making slider movement smoother and more accommodating, reducing tolerance requirements on machined parts, and simplifying assembly. This invention ensures stable and reliable measurement results while shortening detection time, thereby improving production efficiency and effectively controlling production costs. The implementation of this invention has yielded excellent results.
