Description

Technical Field

[0001] This utility model relates to the field of measuring mechanism technology, and in particular to a collision-resistant flexible measuring mechanism. Background Technology

[0002] During the production process, sampling inspections are carried out on the workpieces to promptly scrap any defective workpieces. Therefore, targeted inspection devices are often required during the production process.

[0003] In the prior art, during the automatic measurement process, the device is directly driven by a cylinder, resulting in rigid contact between the device and the part being measured. If the measured hole is under-machined or the hole diameter is too small, the probe will collide with the part being measured, causing damage to the probe. Utility Model Content

[0004] The purpose of this invention is to solve the problem of rigid contact between the device and the part being measured in the prior art, and to propose a collision-resistant flexible measuring mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A collision avoidance flexible measurement mechanism, the collision avoidance flexible measurement mechanism comprising:

[0007] A worktable for sliding-mounted probes;

[0008] A drive cylinder mounted on the workbench;

[0009] A buffer is disposed between the drive cylinder and the probe, through which the drive cylinder flexibly drives the probe horizontally.

[0010] Preferably, the workbench is provided with a slide rail for slidingly mounting the probe.

[0011] Preferably, a bracket is fixedly connected to the workbench, and an abutment head is fixedly installed on the bracket.

[0012] Preferably, the end of the contact head near the probe is wrapped with a layer of rubber.

[0013] Preferably, the buffer includes:

[0014] Connecting plates are installed at both ends of the probe;

[0015] Guide slide rods mounted on the connecting plate;

[0016] A sliding block is slidably mounted on the guide slide rod, and the output end of the drive cylinder is fixedly connected to the sliding block;

[0017] A spring connecting the sliding block and the connecting plate away from the drive cylinder.

[0018] Preferably, the sliding block has a movable through hole for sliding the guide rod.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This invention features a buffer between the output end of the drive cylinder and the probe. By pushing the spring forward and then driving the probe to measure, the probe will only compress the spring when it encounters a hole that is under-machined or has a small diameter, thus preventing the probe from being subjected to a hard impact. This helps to extend the service life of the probe. Furthermore, a stop is provided at the initial position of the probe's return. The stop supports and limits the probe, which helps to ensure the stability of the probe when it returns to the initial position. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figures 1-3A collision-resistant flexible measuring mechanism includes a probe 1, a worktable 2, a slide rail 5, a drive cylinder 3, a buffer 4, a bracket 6, and a contact head 7, with each component arranged as follows:

[0034] The worktable 2 is used to slide the probe 1. The worktable 2 is equipped with a slide rail 5 for sliding the probe 1. The slide rail 5 has an I-shaped longitudinal section and guides and limits the worktable 2, which helps to ensure the singleness of the movement trajectory of the probe 1 and thus improves the stability of the probe 1 during movement. The drive cylinder 3 is installed on the worktable 2, and the buffer 4 is set between the drive cylinder 3 and the probe 1. The drive cylinder 3 flexibly drives the probe 1 horizontally through the buffer 4.

[0035] A further implementation method is that the buffer 4 includes:

[0036] Connecting plates 401 are set at both ends of probe 1. Guide slide rods 402 are installed on connecting plates 401. Sliding blocks 403 are slidably installed on guide slide rods 402. The output end of drive cylinder 3 is fixedly connected to sliding block 403. Sliding block 403 has a movable through hole for sliding guide slide rod 402. The movable through hole provides space for horizontal movement of sliding block 403 on guide slide rod 402 and restricts the movement trajectory of sliding block 403, making the movement trajectory of sliding block 403 singular. And by being fixedly connected to the output end of drive cylinder 3, sliding block 403 will not be affected by gravity, friction and inertia during movement and will not rotate on guide slide rod 402. At the same time, through the connection of drive cylinder 3, sliding block 403 has active extension and retraction.

[0037] Spring 404 is connected between sliding block 403 and connecting plate 401 away from drive cylinder 3. Utilizing the elastic force of spring 404, when the elastic force generated by spring 404 under force is greater than the frictional force between slide rail 5 and probe 1, spring 404 pushes probe 1 forward to perform measurement work. This means that probe 1 is not directly driven by drive cylinder 3, but is pushed forward by spring 404. When probe 1 comes into contact with defective parts, probe 1 cannot continue to move forward. However, since probe 1 is driven by spring 404, the elasticity of spring 404 compensates for the distance probe 1 should have moved forward, thereby avoiding hard impact on probe 1 and helping to extend the service life of probe 1.

[0038] A support 6 is fixedly connected to the workbench 2, and a contact head 7 is fixedly installed on the support 6. The end of the contact head 7 near the probe 1 is wrapped with a layer of rubber. The molecular chains of the rubber can be cross-linked. When the cross-linked rubber is deformed by external force, it has the ability to quickly recover and has good physical and mechanical properties and chemical stability. This provides safety protection when the probe 1 returns to the initial position, helps to avoid the probe 1 from colliding with the support 6 when returning to the initial position, and provides a support point when the probe 1 returns to the initial position, making the movement of the probe 1 more stable.

[0039] The functional principle of this utility model can be explained through the following operation methods:

[0040] Start the drive cylinder 3. The drive cylinder 3 drives the sliding block 403 to move horizontally on the guide slide rod 402, compressing the spring 404. Utilize the elastic force of the spring 404. Since the probe 1 connected to the end of the spring 404 away from the sliding block 403 is movable, the connecting plate 401 pushes the probe 1 forward to perform measurement under the elastic force of the spring 404.

[0041] Start the drive cylinder 3. The drive cylinder 3 drives the sliding block 403 to move horizontally on the guide slide rod 402. The sliding block 403 drives the connecting plate 401 to move backward through the spring 404. The connecting plate 401 drives the probe 1 to return to the initial position and moves against the probe 1 that has returned to the initial position through the contact head 7.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
