Description

Technical Field

[0001] This utility model belongs to the field of hinge calibration technology, specifically relating to a hinge laser calibration device. Background Technology

[0002] In fields such as machinery manufacturing, aerospace, automotive, and robotics, the installation accuracy of rotating pairs such as hinges and shafts is crucial. Whether the mounting holes of the hinge are coaxial and whether the base plane matches the theoretical angle directly affects the smoothness, accuracy, and lifespan of the equipment.

[0003] Problems with existing technology: Currently, the calibration of hinges is usually carried out using equipment such as coordinate measuring machines and large laser trackers. Although these devices are highly accurate, they are expensive, have high environmental requirements, are complex to operate, and are inefficient. They are difficult to deploy quickly during hinge installation, thus affecting the installation efficiency of hinges. Utility Model Content

[0004] The purpose of this invention is to provide a hinge laser calibration device that can coaxially position the mounting hole of the hinge through the linkage of the fixing mechanism, the ranging component and the calibration mechanism, thereby achieving simple structure, convenient operation, low cost and fast, high-precision calibration.

[0005] The specific technical solution adopted by this utility model is as follows: A hinged laser calibration device includes a frame, on the inner side of which a side plate is fixedly mounted; A fixing mechanism is slidably installed on one side of the side plate. The fixing mechanism is used to drive the side plate and the laser calibration mechanism to be fixedly installed with the installation equipment. The laser calibration mechanism includes a servo motor fixedly mounted on one side of the side plate. The servo motor drives the lead screw to move the mounting frame linearly, causing the mounting frame to move the laser beam reflector axially. A ranging component is fixedly mounted on the bottom of the mounting frame, and the mounting frame is used to move the ranging component toward the fixed mechanism.

[0006] The side panels are provided in two sets and are arranged in a mirror image on both sides of the inside of the frame. The two sets of side panels are fixedly connected by a sliding rod, and the mounting bracket is slidably installed with the sliding rod.

[0007] A controller is fixedly installed on the top of the mounting frame, and a ranging component fixedly installed at the bottom of the mounting frame is electrically connected to the controller. Laser beam reflectors are fixedly installed at both ends of the mounting frame, and the laser beam reflectors are electrically connected to the controller.

[0008] The ranging component consists of two laser rangefinders arranged in a mirror image and fixedly installed inside the ranging component. The two laser rangefinders are correspondingly set with the fixing mechanism.

[0009] The fixing mechanism includes an adjusting screw rotatably mounted on one side of the side plate. The adjusting screw is used to drive the fixing plate and the connecting rod to move linearly, so that the connecting rod drives the sliding frame to slide horizontally inside the support rod.

[0010] The fixing mechanism is provided in two sets and is arranged in a mirror image on both sides of the side plate. The fixing plate is T-shaped. The fixing mechanism is used to drive the laser calibration mechanism to be fixedly installed with the installation equipment.

[0011] The connecting rod is fixedly connected between the fixed plate and the sliding frame, and the connecting rod is slidably installed with the side plate.

[0012] The technical effects achieved by this utility model are as follows: This invention utilizes a servo motor fixedly mounted on one side of a side plate. The start of the servo motor drives a lead screw to rotate between the two side plates. The rotation of the lead screw enables the mounting frame to move the laser beam reflector in a linear motion. Simultaneously, the linear motion of the mounting frame also drives the ranging component to move synchronously. By adjusting the distance between the ranging component and the fixing mechanism, the laser emitted by the laser beam reflector can be centered and calibrated. It can also be flexibly adjusted and is convenient for the installation of different types of hinge seats.

[0013] This utility model features an adjusting screw mounted on one side of a side plate, with a fixing plate installed on the external thread of the adjusting screw. Therefore, the fixing plate can move linearly when the adjusting screw is rotated. Since there are two sets of fixing mechanisms, the laser calibration equipment can be flexibly fixed on the mounting surface of the hinge seat through the two sets of fixing mechanisms, thereby achieving flexible and convenient laser calibration.

Detailed Implementation

[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figure 1-4 As shown, a hinged laser calibration device includes a frame 1, and a side plate 2 is fixedly installed on the inner side of the frame 1. A fixing mechanism 4 is slidably installed on one side of the side plate 2. The fixing mechanism 4 is used to drive the side plate 2 and the laser calibration mechanism 3 to be fixedly installed with the installation equipment. The laser calibration mechanism 3 includes a servo motor 31 fixedly installed on one side of the side plate 2. The servo motor 31 is used to drive the lead screw 32 to drive the mounting frame 33 to move linearly, so that the mounting frame 33 drives the laser beam reflector 34 to move axially. A ranging component 35 is fixedly installed at the bottom of the mounting frame 33. The mounting frame 33 is used to drive the ranging component 35 to move toward the fixed mechanism 4.

[0018] See attached document Figure 1 and Figure 2 In this embodiment, two sets of side plates 2 are provided and are arranged in a mirror image on both sides of the inside of the frame 1. The two sets of side plates 2 are fixedly connected by a sliding rod, and the mounting bracket 33 is slidably installed with the sliding rod.

[0019] In the above embodiment, the mounting bracket 33 is internally threaded with a lead screw 32. Therefore, when the servo motor 31 is started, the lead screw 32 can drive the mounting bracket 33 to move axially in the diameter of the two sets of side plates 2, thereby causing the mounting bracket 33 to drive the laser beam reflector 34 to adjust synchronously in the axial direction.

[0020] Furthermore, a controller is fixedly installed on the top of the mounting bracket 33, and a ranging component 35 fixedly installed at the bottom of the mounting bracket 33 is electrically connected to the controller. Laser beam reflectors 34 are fixedly installed at both ends of the mounting bracket 33, and the laser beam reflectors 34 are electrically connected to the controller.

[0021] Furthermore, the ranging component 35 consists of two laser rangefinders arranged in a mirror image and fixedly installed inside the ranging component 35. The two laser rangefinders are also correspondingly set with the fixing mechanism 4. Therefore, during the linear movement of the ranging component 35 driven by the mounting bracket 33, the laser emitted by the laser beam reflector 34 can be adjusted to the center position of the mounting equipment by changing the distance between the laser rangefinder and the fixing mechanism 4, thereby facilitating the installation and fixing of the hinge.

[0022] It should be noted that a display screen is also installed on the surface of the controller, which can directly display the distance values ​​between the two sets of laser rangefinders and the two sets of fixed mechanisms 4. This makes it convenient for the operator to control the forward and reverse rotation and speed of the servo motor 31, thereby adjusting the offset value of the laser beam emitted by the laser beam reflector 34, and further facilitating the installation, calibration and use of the hinge.

[0023] See attached document Figure 1 , Figure 3 and Figure 4 In this embodiment, the fixing mechanism 4 includes an adjusting screw 42 rotatably mounted on one side of the side plate 2. The adjusting screw 42 is used to drive the fixing plate 41 and the connecting rod 43 to move linearly, so that the connecting rod 43 drives the sliding frame 44 to slide horizontally inside the support rod 5.

[0024] In the above embodiment, the fixing mechanism 4 is provided in two sets and is arranged in a mirror image on both sides of the side plate 2. Therefore, the axial position of the fixing plate 41 can be adjusted by rotating the adjusting screw 42. At the same time, the two sets of T-shaped fixing plates 41 can be clamped and fixed with the side of the installation equipment, thereby fixing the laser calibration equipment to one side of the mounting hinge position.

[0025] Specifically, after the fixing mechanism 4 is fixed to the installation equipment, the laser calibration mechanism 3 can be driven by the fixing mechanism 4 to be fixed and installed synchronously with the installation equipment.

[0026] More specifically, since the connecting rod 43 is fixedly connected between the fixed plate 41 and the sliding frame 44, and the connecting rod 43 is slidably installed with the side plate 2, the fixed plate 41 can be flexibly adjusted by adjusting the linkage between the screw 42 and the connecting rod 43, thereby making the laser calibration equipment suitable for installation and use on installation equipment of different sizes.

[0027] The working principle of this utility model is as follows: by rotating the adjusting screw 42, the fixing mechanism 4 is fixed on the surface of the equipment, and the controller starts the two sets of laser rangefinders of the ranging component 35. The two laser rangefinders measure a value with the two sets of fixing plates 41 respectively, and the value is displayed on the display screen of the controller. After the difference between the two ranging values ​​is calculated by the correction system built into the controller, the controller controls the servo motor 31 to start according to the set program and drive the lead screw 32 to rotate. The lead screw 32 drives the laser beam reflector 34 to move axially to adjust to the set position through the mounting bracket 33. At this time, the laser beam reflector 34 can be turned on to emit a laser beam, thereby realizing the laser calibration when the hinge is installed.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
