Description

Technical Field

[0001] This utility model relates to the field of laser interferometer equipment technology, and in particular to a laser interferometer housing structure that is easy to install. Background Technology

[0002] As a high-precision measuring instrument, the laser interferometer is widely used in machine tool calibration, precision component inspection, and other fields. The ease of its installation and positioning directly affects the measurement efficiency. The installation structure of the traditional laser interferometer housing has obvious defects: most of them use bolt fixing or a single magnetic attraction method. Bolt fixing requires repeated tool loading and unloading, which is cumbersome. Although the single magnetic attraction structure can be installed quickly, the strong magnetic attraction can easily cause the equipment to tilt or be bumped during disassembly. Especially in precision measurement scenarios, this may affect the accuracy of the instrument or cause damage to the components.

[0003] Furthermore, the magnetic surfaces of existing magnetically attached housings are mostly perfectly circular, requiring significant external force for detachment and being difficult to control in direction. This can easily cause the instrument to drift in one direction, increasing operational complexity. Therefore, there is an urgent need to design a laser interferometer housing structure that allows for both rapid magnetic attachment and convenient, stable detachment to meet the demands of efficient and precise measurements.

[0004] Therefore, the existing laser interferometer equipment technology field needs further improvement. Utility Model Content

[0005] The purpose of this invention is to provide a laser interferometer housing structure that is easy to install. This structure enables the laser interferometer to be quickly magnetically installed and smoothly detached, and is convenient to operate and reliably positioned.

[0006] To achieve the above objectives, the present invention adopts the following solution:

[0007] A laser interferometer housing structure that is easy to install includes a laser interferometer assembly. The laser interferometer assembly has two rotating components symmetrically arranged front and rear. Each rotating component has a circular part, and one side of each circular part has a flat magnetic suction surface. The laser interferometer assembly has a rotating shaft assembly. A reverse transmission rod worm gear assembly that can control the two circular parts to rotate in opposite directions is provided between the rotating shaft assembly and the two circular parts.

[0008] Furthermore, the rotating assembly includes a slot disposed at the bottom of the laser interferometer assembly, a rotating seat disposed in the slot, and a rotating shaft rotatably disposed in the rotating seat.

[0009] Furthermore, the rotating shaft assembly includes a rotating shaft seat disposed at the bottom of the laser interferometer assembly, and a rotating shaft body is rotatably mounted in the rotating shaft seat, the rotating shaft body covering the two circular parts.

[0010] Furthermore, the reverse transmission worm gear assembly includes a forward-rotating worm and a reverse-rotating worm respectively disposed in the front half and rear half of the rotating shaft. The outer walls of the two circular parts are respectively provided with a forward worm wheel and a reverse worm wheel. The forward-rotating worm and the forward worm wheel mesh for transmission, and the reverse-rotating worm and the reverse worm wheel mesh for transmission.

[0011] Furthermore, the reverse transmission rod worm gear assembly is provided with a control handle for controlling the movement of the reverse transmission rod worm gear assembly.

[0012] Furthermore, the circular component consists of, from the inside out, a neodymium iron boron magnetic core layer, a nanocrystalline alloy transition layer, and an amorphous alloy coating layer.

[0013] In summary, the advantages of this utility model over the prior art are:

[0014] This invention addresses the shortcomings of existing laser interferometer equipment technology. Through its structural design, it offers the following advantages: rapid installation and smooth disassembly. The flat magnetic surface of the circular component enables rapid magnetic installation of the laser interferometer. The reverse transmission rod worm gear assembly controls the two circular components to rotate in opposite directions, causing the flat magnetic surface to evenly detach from the attracted surface and lift upwards, avoiding unidirectional offset of the equipment. The disassembly process is smooth and controllable, solving the problem of difficult disassembly of traditional magnetic structures. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model provides an easy-to-install laser interferometer housing structure, including a laser interferometer assembly 1. The laser interferometer assembly 1 has two symmetrically arranged rotating components 2. Each rotating component 2 has a circular part 3, and one side of each circular part 3 has a flat-cut magnetic suction surface 4. A rotating shaft assembly 5 is provided on the laser interferometer assembly 1. A reverse transmission rod worm gear assembly 6, capable of controlling the two circular parts 3 to rotate in opposite directions, is provided between the rotating shaft assembly 5 and the two circular parts 3. The laser interferometer assembly 1 serves as the main body, with the two symmetrically arranged rotating components 2 supporting the rotation of the circular parts 3. The circular parts 3 achieve magnetic attraction and fixation to the object being attracted through the flat-cut magnetic suction surface 4. The rotating shaft assembly 5 provides a rotational basis for the reverse transmission rod worm gear assembly 6, which controls the two circular parts 3 to rotate in opposite directions, allowing the flat-cut magnetic suction surface 4 to smoothly detach from the attracted surface, thus achieving convenient installation and disassembly.

[0022] The rotating component 2 of this utility model includes a slot 201 disposed at the bottom of the laser interferometer component 1. A rotating seat 202 is disposed in the slot 201, and a rotating shaft 203 is rotatably disposed in the rotating seat 202. The slot 201 of the rotating component 2 provides installation space for the rotating parts. The rotating seat 202 is fixed in the slot 201, and the rotating shaft 203 rotates in the rotating seat 202, providing rotational support for the circular part 3 and the reverse transmission rod worm gear assembly 6, ensuring smooth rotation.

[0023] The rotating shaft assembly 5 of this utility model includes a rotating shaft seat 501 disposed at the bottom of the laser interferometer assembly 1. A rotating shaft body 502 is rotatably mounted inside the rotating shaft seat 501, and the rotating shaft body 502 covers the two circular parts 3. The rotating shaft seat 501 of the rotating shaft assembly 5 is fixed to the bottom of the laser interferometer assembly 1, and the rotating shaft body 502 rotates inside the rotating shaft seat 501 and covers the two circular parts 3, providing stable rotational support for the reverse transmission rod worm gear assembly 6 and ensuring the coaxiality and stability of the transmission structure.

[0024] The reverse transmission rod worm gear assembly 6 of this utility model includes a forward-rotating worm gear 601 and a reverse-rotating worm gear 602 respectively disposed in the front half and rear half of the rotating shaft 203.

The forward-rotating worm gear 601 and the forward worm wheel 603 mesh for transmission, and the reverse-rotating worm gear 602 and the reverse worm wheel 604 mesh for transmission. When the rotating shaft 203 rotates, the two circular parts 3 will rotate in opposite directions, aiming to make the flat magnetic attraction surface 4 on the circular parts 3... To better detach from the attracted surface and lift it upwards, and to prevent the laser interferometer assembly 1 from moving in one direction, the flat-cut magnetic attraction surface 4 detaches from the attracted surface better when it rotates, thus completing the detachment process more effectively. The forward-rotating worm 601 of the reverse transmission rod worm assembly 6 meshes with the forward worm wheel 603, and the reverse-rotating worm 602 meshes with the reverse worm wheel 604. When the rotating shaft 203 rotates, the two circular parts 3 are driven to rotate in opposite directions by the worms with opposite threads, so that the flat-cut magnetic attraction surface 4 detaches from the attracted surface evenly and lifts upwards, avoiding unidirectional deviation of the instrument and achieving smooth detachment.

[0025] The reverse transmission rod worm gear assembly 6 of this utility model is provided with a control handle 100 for controlling the movement of the reverse transmission rod worm gear assembly 6; the control handle 100 is connected to the rotating shaft 203 of the reverse transmission rod worm gear assembly 6, and the rotating shaft 203 is driven to rotate by manually rotating the handle, thereby controlling the reverse transmission rod worm gear assembly 6 to drive the circular part 3 to rotate in the opposite direction, so as to realize convenient control of the opening and closing state of the magnetic suction surface.

[0026] The circular component 2 of this invention consists of, from the inside out, a neodymium iron boron magnetic core layer, a nanocrystalline alloy transition layer, and an amorphous alloy coating layer.
