Description

Technical Field

[0001] The utility model relates to the technical field of optical sensing detection, in particular to an optical fiber detection device for the straightness of a machine tool guide rail. Background Art

[0002] In modern manufacturing, machine tools are key equipment used to process various precision parts and components. The machining accuracy of machine tools directly affects the quality and performance of the final product. The guide rails of machine tools are an important component that supports and guides the movement of machine tools. Their straightness is crucial to the movement accuracy of machine tools. With the development of the manufacturing industry and the continuous growth of demand, the requirements for machine tool machining accuracy are also increasing. The straightness of machine tool guide rails is one of the key factors affecting machining accuracy. Therefore, accurately measuring and monitoring the straightness of machine tool guide rails has become one of the important tasks in the manufacturing industry.

[0003] Traditional guide rail straightness detection methods usually use high-precision measuring equipment such as laser interferometers, swing-arm measuring instruments, laser rangefinders, and position sensors such as piezoelectric sensors and encoders. These methods need to be performed in a laboratory environment, are cumbersome to operate, and require professional technicians to operate and process data. Although these methods can achieve high-precision guide rail straightness measurement, the equipment is expensive, the operation is complicated, and real-time monitoring cannot be achieved. They cannot meet the needs of modern manufacturing for machine tool guide rail accuracy detection and are very inconvenient.

[0004] Therefore, there is an urgent need to provide a machine tool guide rail straightness optical fiber detection device to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the disadvantages of the prior art and provide a machine tool guide rail straightness optical fiber detection device.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a machine tool guide rail straightness optical fiber detection device, comprising a bottom plate, a mounting block is installed on the top of the bottom plate near one side, an optical module is installed on the top of the mounting block, and a display screen and an operating table are installed on the top of the optical module respectively;

[0007] Two linear guides are fixedly connected to the top of the base plate, a servo motor is installed on the top of the base plate near the linear guides, a lead screw is fixedly connected to the output end of the servo motor, and a support block is fixedly connected to the other end of the two linear guides, and a support hole corresponding to the lead screw is opened inside the support block;

[0008] The outer wall of the screw rod is slidably connected with a slider, the front end and the rear end of the slider are fixedly connected with two telescopic rods, and an adjustment detection mechanism is arranged between every two telescopic rods.

[0009] The utility model is further configured as follows: the optical module is composed of a light source, a lens system, an optical fiber sensor and a data processing unit.

[0010] Through the above technical solution, the light source provides a stable light beam, and the lens system is used to adjust and focus the light beam to ensure that the light can accurately illuminate the designated area. The fiber optic sensor can accurately receive and convert the reflected light signal. The data processing unit is responsible for receiving, processing and analyzing the data transmitted by the fiber optic sensor. By digitalizing and analyzing the data through algorithms, the straightness of the machine tool guide rail can be obtained and relevant evaluation and feedback information can be provided.

[0011] The utility model is further configured as follows: the outer wall of the screw rod is fitted to the inner wall of the support hole.

[0012] Through the above technical solution, the stability of the screw rod in the support hole can be increased by fitting the outer wall of the screw rod with the inner wall of the support hole. This fitting design can effectively reduce the shaking and deviation of the screw rod during movement, thereby improving the stability and accuracy of the entire mechanism.

[0013] The utility model is further configured as follows: the slider is connected to the screw rod in a spiral manner.

[0014] Through the above technical solution, the spiral connection method can effectively convert the rotational motion of the screw rod into the linear motion of the slider, thereby realizing efficient rotation transmission.

[0015] The utility model is further configured as follows: the adjustment detection mechanism includes a connecting block fixedly connected to the other end of the telescopic rod, the other end of the connecting block is fixedly connected to a first fixing block, the front end of the first fixing block is rotatably connected to two first auxiliary wheels, the front end of the first fixing block is fixedly connected to a connecting plate near the top position, an optical reflector is installed on the top of the connecting plate, the bottom of the connecting plate is rotatably connected to a driving wheel, the other end of the connecting plate is fixedly connected to a second fixing block, the inner end of the second fixing block is rotatably connected to two second auxiliary wheels, and two adjustment screws are rotatably connected between the first and second fixing blocks and the connecting plate.

[0016] Through the above technical solution, before performing the detection work, the adjustment detection mechanism is first assembled according to the installation steps, and then the distance between the first fixed block and the second fixed block and the connecting plate is adjusted by turning the adjusting screw, so as to ensure that the auxiliary wheels inside the first fixed block and the second fixed block can fit on the corresponding linear guide rail. When the slider moves, it can drive the adjustment detection mechanism to move. When the straight line angle of the linear guide rail deviates, the light reflected back by the optical reflector will be received by the optical fiber sensor of the optical module and analyzed by the data processing unit, and finally the processing result will be displayed on the display screen.

[0017] The utility model is further configured as follows: the first auxiliary wheel and the second auxiliary wheel are both fitted to the corresponding outer wall of the linear guide rail.

[0018] Through the above technical solution, a good fitting design can ensure stable and consistent contact between the auxiliary wheels and the linear guide rails, thereby improving the accuracy and repeatability of the movement, which is especially important for application scenarios that require high-precision positioning and control.

[0019] The utility model is further configured as follows: the optical fiber sensors correspond one to one with the optical reflectors.

[0020] Through the above technical solution, this one-to-one design can ensure that each detection point has a dedicated sensor for measurement, so that accurate measurement of each position can be achieved, interference and errors between sensors can be avoided, and the accuracy of measurement can be improved.

[0021] The beneficial effects of the utility model are as follows:

[0022] 1. The utility model designs an adjustment detection mechanism. Since the adjustment detection mechanism is assembled and fitted on the outer wall of the target linear guide rail, when the adjustment detection mechanism moves on the target linear guide rail, when the target linear guide rail has a slight deviation, it will be detected. The detection accuracy can be effectively improved by adjusting the detection mechanism.

[0023] 2. The utility model designs a modular adjustment detection mechanism and an adjustment screw. Before performing the detection work, the detection personnel can assemble the adjustment detection mechanism according to the size of the target linear guide rail, so that the adjustment detection mechanism can better fit the outer wall of the target linear guide rail. The adjustment screw can make the adjustment detection mechanism face linear guide rails of different sizes, thereby improving the versatility of the device. BRIEF DESCRIPTION OF THE DRAWINGS
