Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary tools, and in particular to a centering device. Background Technology

[0002] The current centering equipment consists of five parts: a centering output module, motion guide rails, a centering motion module, an equipment structure module, and a power system. The centering structure is located on both sides of the centering wheel, with two guide rails on each side guiding the movement of the centering module. A belt drive or bearings combined with a crank control the centering distance. The equipment structure module is pre-associated with a centering reference point. Driven by the power system, the centering rod (or pulley system) moves the centering module along the guide rails to achieve centering.

[0003] Currently, existing technologies have the following shortcomings:

[0004] 1. The centering module's movement direction must be controlled by a guide rail to prevent the centering module from swaying and causing centering errors; the guide rail direction and the centering direction must be consistent in order to control the module's movement. Therefore, this type of device is easily limited by space (generally more than 1000mm).

[0005] 2. Crank and belt drive methods are difficult to obtain a large power arm. Therefore, pneumatic or electric power is required, equipped with a dedicated air circuit or battery. Usually, lifting tools are also needed in the application scenario to reduce the difficulty of moving the equipment. It cannot be operated by a single person, and it is even more difficult to achieve manual centering.

[0006] 3. Due to the influence of the guide rail arrangement, it is difficult to achieve centering activities in a narrow area.

[0007] Therefore, there is an urgent need for a centering device that can achieve centering activities in a narrow area and can be operated by a single person. Utility Model Content

[0008] In view of this, the present invention provides a centering device that can realize centering activities in a narrow area and can be operated by a single person.

[0025] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0026] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0027] This utility model discloses a centering device.

[0028] Reference Figures 1-2 A centering device includes a control element, a main rod 1, and a centering mechanism. The centering mechanism includes multiple rocker arm assemblies, each with a functional rod rotatably mounted on the main rod. The end of each functional rod has a positioning part that abuts against the component to be centered. The control element can be manipulated to rotate the functional rods, causing the corresponding positioning parts to move closer to each other and abut against the component to be centered to complete centering, or to move away from each other and separate from the component to be centered. This device uses the control element to drive the functional rods to rotate, enabling the positioning parts to complete the centering activity of the component to be centered, thus achieving centering activities in narrow areas and allowing for single-person operation.

[0029] In this embodiment, the operating element is slidably mounted on the main rod 1 along the axial direction. Each functional rod includes a rocker arm and a centering rod. The rocker arm is rotatably mounted on the operating element, and the centering rod is rotatably mounted on the main rod 1. One end of the centering rod is rotatably connected to the corresponding rocker arm, and the other end extends outward through the rotating part of the centering rod and the main rod 1 and connects to the positioning part. By rotating the rocker arm, the centering rod is driven to rotate inward so that the positioning part can complete the centering movement of the part to be centered, or rotate outward so that adjacent positioning parts are separated from each other and from the part to be centered. Centering movement in a narrow area can be achieved, and it can be operated by a single person.

[0030] The centering rod 5 is provided with a rotating part 9, a rotating part 10, a bending part 11, and a positioning part in sequence along the axial direction of the main rod 1. The rotating part 9 is used to rotatably connect with the rocker arm 4. The rotating part 10 is rotatably fitted on the main rod 1. The positioning part is used to contact the part to be centered. During the sliding process of the operating member along the axial direction, the rocker arm 4 is driven to rotate, which drives the centering rod 5 to rotate, so that the positioning parts of the rocker arm assembly 1 and the rocker arm assembly 2 move closer to each other and contact the part to be centered to complete the centering, or move away from each other and separate from the part to be centered. This device realizes the longitudinal transmission of the operating member and the lateral centering movement of the positioning part through the rocker arm assembly 1 and the rocker arm assembly 2, realizes the centering movement in a narrow area, and can be operated by a single person.

[0031] Specifically, the joystick assembly includes joystick assembly one and joystick assembly two. Joystick assembly one includes joystick one 2 and centering rod one 4 rotatably configured on joystick one 2. Joystick assembly two includes joystick two 3 and centering rod two 5 rotatably configured on joystick two 3. Joystick one 2 and joystick two 3 are respectively rotatably configured on the control element.

[0032] In this embodiment, as the operator drives the control member to slide along the axial direction of the main rod 1 away from the positioning part, the rocker arm 1 2 and rocker arm 2 3 rotate to drive the bent parts of the corresponding centering rod 1 4 and centering rod 2 5 to move closer to each other, so that the two positioning parts move closer to each other to complete the centering; similarly, as the operator drives the control member to slide along the axial direction of the main rod 1 towards the positioning part, the two positioning parts move away from each other and separate from the part to be centered.

[0033] In this embodiment, the control element includes a sliding rod 8, and a gripping part 7 is provided on the main rod 1. The sliding rod 8 is coaxially and slidably disposed between the connecting part 12 and the gripping part 7 of the main rod 1. The sliding rod 8 slides along the axial direction of the main rod 1, transmitting the axial sliding motion of the main rod 1 to the corresponding rocker arm 2 and rocker arm 3, realizing the centering movement of the corresponding positioning part. This not only achieves precise centering of the positioning part, but also greatly improves the convenience and efficiency of operation. The lateral movement of the positioning part can be realized through simple longitudinal sliding, thereby meeting various centering requirements. Furthermore, a bracket is provided on the sliding rod 8, and the rocker arm 2 and rocker arm 3 are rotatably disposed on the bracket, improving the stability of the rocker arm installation.

[0034] In this embodiment, at least one rocker arm 4 is provided, and rocker arm 2 and rocker arm 3 are symmetrically arranged on the operating member along the axial direction of the main rod 1. One or more rocker arms may be provided; in this embodiment, only one rocker arm 4 is provided.

[0035] In this embodiment, a connecting part 12 is provided on the main rod 1, and a rotating part 10 is rotatably fitted onto the connecting part 12.

[0036] In this embodiment, the cross-section of the centering rod is approximately L-shaped. The straight-line distance between the rotating part 9 and the main rod 1 is greater than the straight-line distance between the bending part 11 and the main rod 1. The centering rod 5 allows the positioning part to extend into a narrow area. The bending part 11 changes the direction of power transmission, enabling centering activities in a narrow area. This allows the positioning part to perform precise centering operations within a limited space.

[0037] The positioning section is equipped with a positioning element 6, which is used to position the part to be aligned. The positioning element 6 can be adapted to the shape of the part to be aligned, such as by using a positioning pin or a positioning table, to make positioning more accurate and convenient, and to achieve alignment of the workpiece position and profile. The positioning element 6 can be fixedly set on the positioning section or detachably set on the positioning section, such as by threaded connection, to realize the multi-functionality of the alignment device. By assembling different positioning elements 6, the alignment requirements of different parts can be met, thus improving applicability.

[0038] This utility model is applicable to activities requiring short-distance centering, such as centering assembly, centering measurement, and centering calibration. It is a device that requires external positioning and can achieve centering control.

[0039] This article uses the centering assembly of a car's rear door sill as an example:

[0040] In traditional assembly schemes for the rear door sill, the rear door sill and the rear door latch cannot be adjusted relative to each other. Since the position of the rear door latch is related to the rear door posture, after adjusting the latch position in conjunction with the rear door, the latch will not be centered relative to the rear door latch hole, making it impossible to adjust the sill and compromising the appearance quality.

[0041] The centering device of this utility model allows for the design of an adjustable rear door sill in the vehicle width direction. The sill's posture is adjusted to ensure the rear door latch is centered. After the latch is adjusted, the rear door sill guard plate is installed, and then the latch positioning device is used to pull down the handle to complete the centering. The centering process is as follows: First step: Grasp the sliding rod 8 with your right hand, hook your thumb onto the grip, and engage the positioning part with the rear door latch; Second step: Visually inspect the device for verticality; Third step: Press down on the handle to complete the centering.

[0042] This centering device is lightweight, occupies little space, and is easy and quick to operate, allowing for single-person, one-handed operation.

[0043] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. The above descriptions are only preferred embodiments of this utility model. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this utility model, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without modification, should all be considered within the protection scope of this utility model.
