Novel double-probe detection module

Abstract

The invention relates to a novel double-probe detection module, which can quickly measure height data of a product, and can shorten the detection time while ensuring that a measurement result is stable and reliable. According to the invention, two common modules are combined into one module, and the distance between the left probe and the right probe is closer, so that the switching time is greatly shortened when the probes are switched for detection, and the production efficiency is improved. Different from hard contact blocking of a traditional probe, the sliding block is subjected to secondary speed reduction through the oil pressure buffer and the plunger buffer, structural vibration is effectively and rapidly eliminated, and therefore the detection time is shortened, the detection precision is improved, and meanwhile the problem of structural deformation caused by hard contact impact is solved. The left slide block and the right slide block use two groups of guide rails, so that the slide blocks are more stable, and the stability of a measurement result is ensured. The air cylinder and the sliding block are connected through the universal joint, so that the sliding block moves more smoothly, inclusiveness is higher, the tolerance requirement for a machined part is lowered, and meanwhile the assembling difficulty is lowered.

Description

Technical Field

[0001] The present invention relates to a novel dual-probe detection module, and more specifically to a novel dual-probe detection module which can realize rapid measurement of product height data, shorten detection time while ensuring stable and reliable measurement results, thereby improving production efficiency and effectively controlling production costs. Background Art

[0002] At present, most probe measurements are single-probe measurements. When the target detection requirements are quite different, it is necessary to replace the probe or probe, or directly use two probe modules 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 the advantages of reliable results and not easily affected by external interference. However, the existing contact measurement method has the following defects and shortcomings in certain specific occasions: when using a single probe module for measurement, it is necessary to replace the probe or the probe body at the same time when changing the product. This operation usually requires professionals to operate and is cumbersome; when using two probe modules for measurement, due to the need to frequently switch between two sets of probes and the need to consider the need to prevent interference, part of the production time is usually sacrificed; the current mechanism using a motion module to drive two probes, the distance between the two probes is generally far, and the time required for switching is long, which is not suitable for occasions with high measurement speed requirements; the probe of the existing measurement structure is a probe of a blocking buffer structure, which is mainly hard blocking. During measurement, the probe needs a longer time to eliminate structural vibration, thereby reducing errors, so the structure needs to be improved. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a new dual-probe detection module that can quickly measure product height data, shorten the detection time while ensuring stable and reliable measurement results, thereby improving production efficiency and effectively controlling production costs.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a new type of double-probe detection module, including a base plate, a left cylinder, a left slide rail, a left lower block, a right cylinder, a right slide rail, and a right lower block. The left cylinder, the left slide rail, and the left lower block are fixed to the left side of the base plate with screws, and the right cylinder, the right slide rail, and the right lower block are fixed to the right side of the base plate with screws. The lower part of the left cylinder is connected to the left universal joint, and the left universal joint is connected to the left slider. The left slider is installed on the left slide rail, and the left slider is provided with a left lower probe fixing block and an upper left probe fixing block, a left probe is arranged between the lower left probe fixing block and the upper left probe fixing block, an upper left block is installed on the top of the left slider, the upper left block is connected to the left hydraulic buffer, the lower part of the right cylinder is connected to the right universal joint, the right universal joint is connected to the right slider, the right slider is installed on the right slide rail, a lower right probe fixing block and an upper right probe fixing block are arranged on the right slider, a right probe is arranged between the lower right probe fixing block and the upper right probe fixing block, an upper right block is installed on the top of the right slider, and the upper right block is connected to the right hydraulic buffer.

[0005] The beneficial effect of the present invention is that, compared with the traditional probe module structure, the present invention has the following effects: the present invention combines the usual two modules into one module, and at the same time, the distance between the left and right probes is also closer, which greatly shortens the switching time when switching probe detection, thereby effectively improving production efficiency. The present invention is different from the hard contact blocking of traditional probes. The present invention uses a hydraulic buffer and a plunger buffer to perform secondary deceleration on the slider, which effectively and quickly eliminates structural vibration, thereby reducing the detection time and improving the detection accuracy. At the same time, it also alleviates the problem of structural deformation caused by hard contact impact. The left and right sliders of the present invention use two sets of guide rails, and the sliders are more stable, ensuring the stability of the measurement results. A universal joint is used between the cylinder and the slider to make the slider movement smoother and more inclusive, reduce the tolerance requirements for the workpiece, and also reduce the difficulty of assembly.

[0014] A novel double-probe detection module for implementing the present invention comprises a base plate (1), a left cylinder (2), a left slide rail (3), a left lower block (21), a right cylinder (11), a right slide rail (12), and a right lower block (22). The left cylinder (2), the left slide rail (3), and the left lower block (21) are fixed to the left side of the base plate (1) by screws, and the right cylinder (11), the right slide rail (12), and the right lower block (22) are fixed to the right side of the base plate (1) by screws. The lower part of the left cylinder (2) is connected to the left universal joint (4), and the left universal joint (4) is connected to the left slider (7). The left slider (7) is installed on the left slide rail (3), and a left lower probe fixing block (8) and a left upper probe fixing block (9) are arranged on the left slider (7). A left probe (10) is arranged between the probe fixing block (8) and the upper left probe fixing block (9); an upper left block (5) is installed on the top of the left slider (7); the upper left block (5) is connected to the left oil pressure buffer (6); the lower part of the right cylinder (11) is connected to the right universal joint (13); the right universal joint (13) is connected to the right slider (16); the right slider (16) is installed on the right slide rail (12); a lower right probe fixing block (17) and an upper right probe fixing block (18) are arranged on the right slider (16); a right probe (19) is arranged between the lower right probe fixing block (17) and the upper right probe fixing block (18); an upper right block (14) is installed on the top of the right slider (16); the upper right block (14) is connected to the right oil pressure buffer (15).

[0015] A novel double-probe detection module of the present invention is implemented, wherein a plunger buffer (20) is respectively arranged on a lower left block (21) and a lower right block (22). A lower left probe fixing block (8) and an upper left probe fixing block (9) can clamp a left probe (10), and a lower right probe fixing block (17) and an upper right probe fixing block (18) can clamp a right probe (19).

[0016] The novel dual-probe detection module of the present invention is implemented in the following steps:

[0017] The left module moves as follows: when the left probe is used, the left cylinder changes from a retracted state to an extended state, the upper left block fixed on the left slider first contacts the left hydraulic buffer and decelerates, then contacts the plunger buffer and finally stops, and then starts measuring. After the measurement data is read, the left cylinder changes from an extended state to a retracted state, and the test ends after it is retracted into place. This structure can effectively and quickly eliminate structural vibration through secondary deceleration, thereby reducing detection time and improving detection accuracy, while also alleviating the problem of structural deformation caused by long-term impact.

[0018] Similarly, the right module moves as follows: when the right probe is used for detection, the module moves to the top of the target and repeats the above-mentioned left module action steps to complete the measurement of the right module action.

[0019] A new type of dual-probe detection module of the present invention is implemented. During the assembly and measurement of the mechanism, contact measurement is a traditional and commonly used height measurement method. Compared with 3D laser measurement, this device has the advantages of reliable results and not being easily affected by external interference. The present invention is implemented with good results.
