Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of assembly tooling positioning assistance, and more specifically, to a positioner for assembly tooling. Background Technology

[0002] In the field of mechanical assembly, assembly fixtures are core auxiliary equipment that ensures precise alignment of parts and improves production efficiency. Positioners, as a key component of assembly fixtures, directly determine assembly quality and finished product qualification rate through their positioning accuracy. Whether it's assembling automotive parts, splicing mechanical equipment, or integrating electronic components, all rely on positioners to achieve precise alignment of parts, thus requiring extremely high stability and accuracy. However, traditional assembly fixtures often use handheld positioners for positioning and installation, which suffers from significant drawbacks such as large positioning errors and poor stability, severely restricting assembly efficiency and product quality.

[0003] Handheld positioners rely on operators to manually control the positioning position and angle. During prolonged operation, hand fatigue can easily cause the positioner to shift. Simultaneously, vibrations and airflow interference at the assembly site, or operator misjudgments of the positioning reference, can all lead to positioning errors. For high-precision assembly requirements (such as precision gears and electronic module docking), this can result in misaligned parts, uneven gaps, and even component jamming or functional failure, significantly increasing rework costs.

[0004] Furthermore, handheld positioning devices require single or multiple people to collaborate on positioning and installation operations. When assembling large tooling components, it is difficult to maintain the stability of the positioning device and the alignment rhythm of the parts simultaneously, easily leading to asynchrony between positioning and installation, further expanding the error range. For batch assembly production, the poor consistency of manual positioning results in inconsistent product quality within the same batch, failing to meet standardized production requirements. Therefore, developing a positioning device for assembly tooling that can replace handheld operation and improve positioning accuracy and stability has become an urgent need to solve industry pain points. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a positioner for assembly tooling, which solves the technical problem that traditional assembly tooling often uses handheld positioners for positioning and installation, resulting in large positioning errors and poor stability.

A support bolt is threadedly connected to the side end face of the stabilizing frame. One end of the support bolt is supported on the outer surface of the guide frame.

[0007] As a further technical solution, a drive screw is vertically rotatably connected inside the column. The drive screw is driven to rotate by electricity. The positioner body is horizontally and vertically slidably connected inside the column. One end of the positioner body is connected to the drive screw through a threaded connection.

[0008] As a further technical solution, a reflective block is provided on the side end face of the base frame, and an infrared distance sensor is provided on the bottom of the locator body, with the position of the infrared distance sensor corresponding to the position of the reflective block.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-3 As shown, a positioner for an assembly tooling according to an embodiment of the present disclosure is illustrated, comprising: A rectangular plate 1 and a base frame 2, wherein the rectangular plate 1 is mounted on the base frame 2; A fastening and fixing component 5 is disposed at the bottom of the rectangular plate 1; The locator body 3 and the adjusting positioning component 4 are provided. The locator body 3 is disposed on the rectangular plate 1, and the adjusting positioning component 4 is disposed between the locator body 3 and the rectangular plate 1. The adjustment and positioning assembly 4 includes a guide frame 4-1, which is horizontally fixed to the surface of the rectangular plate 1. A column 4-2 is horizontally slidably connected inside the guide frame 4-1. A stabilizing frame 4-3 is provided on one side of the bottom of the column 4-2. A support bolt 4-4 is threadedly connected to the side end face of the stabilizing frame 4-3. One end of the support bolt 4-4 is supported on the outer surface of the guide frame 4-1. A drive screw 4-5 is vertically rotatably connected inside the column 4-2. The drive screw 4-5 is electrically driven to rotate. The locator body 3 is horizontally and vertically slidably connected inside the column 4-2. One end of the locator body 3 is threadedly connected to the drive screw 4-5. A reflector block 4-6 is provided on the side end face of the base frame 2. An infrared distance sensor 4-7 is provided at the bottom of the locator body 3. The position of the infrared distance sensor 4-7 corresponds to the position of the reflector block 4-6.

[0024] In some examples, in order to achieve precise adjustment of the height and horizontal position of the locator body 3 and meet the different positioning requirements of the assembly tooling, an adjustment positioning component 4 is designed. This component includes a guide frame 4-1 with the rectangular plate 1 horizontally fixed on the surface, which provides a horizontal sliding track for the column 4-2. The bottom of the column 4-2 is embedded in the guide frame 4-1 and can move smoothly along the length of the guide frame 4-1, providing a basis for adjusting the horizontal position of the locator body 3. The stabilizing frame 4-3 on one side of the bottom of the column 4-2 has an L-shaped structure. The support bolt 4-4 in its side end face extends laterally through threaded engagement, with one end supported on the outer surface of the guide frame 4-1. By tightening the support bolt 4-4, the friction with the guide frame 4-1 can be increased, thereby locking the horizontal position of the column 4-2.

[0025] The vertically rotating drive screw 4-5 inside the column 4-2 is connected to the upper and lower ends of the column 4-2 through bearings at both ends to ensure stable rotation of the screw. The drive screw 4-5 is electrically driven (can be equipped with a servo motor). The positioner body 3 is vertically slidably connected in the slide groove inside the column 4-2, and one end of it is engaged with the drive screw 4-5 through a threaded sleeve to form a vertical lifting structure.

[0026] The reflective block 4-6 on the side end face of the base frame 2 corresponds to the position of the infrared distance sensor 4-7 on the bottom of the locator body 3, which can detect the relative distance between the locator body 3 and the base frame 2 in real time and help judge the positioning accuracy.

[0027] During operation, loosen the support bolt 4-4, push the column 4-2 to slide along the guide frame 4-1 to the target horizontal position, and then tighten the support bolt 4-4 to lock the column 4-2; then the electric drive screw 4-5 rotates, and through the threaded transmission, drives the positioner body 3 to rise and fall vertically along the column 4-2 to adjust to the required height; the infrared distance sensor 4-7 emits a signal to the reflector block 4-6, and after receiving the feedback signal, the positioning position can be calibrated to ensure accurate adjustment.

[0028] The horizontal guidance of the guide frame 4-1 ensures smooth movement of the column 4-2, the locking function of the support bolt 4-4 prevents positioning deviation, the electric drive of the drive screw 4-5 enables stepless adjustment of the height of the positioner body 3, and the cooperation of the infrared distance sensor 4-7 and the reflector block 4-6 improves positioning accuracy. This component achieves multi-dimensional positioning of the positioner body 3 through independent adjustment in the horizontal and vertical directions, adapting to the positioning requirements of different assembly tooling and improving assembly flexibility and accuracy.

[0029] like Figures 1-3 As shown in the figure, the fastening and fixing assembly 5 in this embodiment includes a pair of rectangular grooves 5-1. The rectangular grooves 5-1 are formed at both ends of the bottom of the base frame 2. Fastening studs 5-2 are horizontally rotatably connected in the rectangular grooves 5-1. Clamping plates 5-3 are horizontally slidably connected in the rectangular grooves 5-1. An inner frame 5-4 is provided in the rectangular grooves 5-1. The inner frame 5-4 is slidably fitted with the clamping plates 5-3. The fastening studs 5-2 and the clamping plates 5-3 are connected by threaded engagement. The clamping plates 5-3 are at 90° relative to the base frame 2. A screwing block 5-5 is provided at one end of the fastening studs 5-2.

[0030] In some examples, to achieve a stable fixation between the base frame 2 and the equipment and to provide a stable foundation for adjusting the positioning component 4, a clamping and fixing component 5 is designed. This component includes rectangular grooves 5-1 at both ends of the bottom of the base frame 2 extending along the width of the base frame 2. The two ends of the horizontally rotating fastening studs 5-2 in the groove are connected to the side walls of the rectangular groove 5-1 through bearings. The screw block 5-5 at one end of the stud (which can be designed as a hexagon or a structure with a handle) is easy to drive manually or with tools to rotate. The clamping plate 5-3 in the rectangular groove 5-1 is a vertical plate and is slidably connected to the slide rail 6 in the rectangular groove 5-1 through the bottom slider. The clamping plate 5-3 and the inner frame 5-4 fixed in the rectangular groove 5-1 are slidably fitted together. The inner frame 5-4 is a vertical rod structure. The through hole at the side end of the clamping plate 5-3 cooperates with the inner frame 5-4 to restrict the clamping plate 5-3 to move only in the horizontal direction and prevent it from rotating.

[0031] The clamping plate 5-3 and the fastening stud 5-2 are connected by a threaded engagement, and the threads of the fastening stud 5-2 in the rectangular grooves 5-1 at both ends of the base frame 2 are turned in opposite directions. When the screwing block 5-5 is rotated, the clamping plates 5-3 on both sides can move closer or further away simultaneously. The clamping plate 5-3 is at 90° relative to the base frame 2, that is, the clamping plate 5-3 is perpendicular to the bottom surface of the base frame 2. When clamped, it can fit against the mounting surface or edge of the equipment to form a lateral clamping force.

[0032] During operation, place the base frame 2 in the designated position on the equipment, ensuring the equipment's mounting structure is positioned between the two clamping plates 5-3. Rotate the screw block 5-5 to drive the fastening stud 5-2 to rotate. Through threaded transmission, this causes the two clamping plates 5-3 to move synchronously towards the center along the rectangular groove 5-1 until the clamping plates 5-3 are tightly fitted against the equipment's mounting structure. The clamping force then secures the base frame 2 to the equipment. For disassembly, simply rotate the screw block 5-5 in the opposite direction to separate the clamping plates 5-3. The sliding sleeve of the inner frame 5-4 ensures smooth movement of the clamping plates 5-3, preventing misalignment. The reverse thread design of the fastening stud 5-2 allows for synchronous adjustment of the clamping plates 5-3, ensuring uniform clamping force. The convenient operation of the screw block 5-5 requires no complex tools, enabling quick assembly and disassembly of the base frame 2.

[0033] This component provides stable support for the entire positioner through a robust lateral clamp, preventing the base frame 2 from shifting during positioning adjustments and ensuring positioning accuracy and assembly safety.

[0034] For example, such as Figures 1-3 As shown, the base frame 2 and the inner side of the guide frame 4-1 are both provided with slide rails 6, and the slide rails 6 are connected to the bottom of the column 4-2 by threaded connection.

[0035] In some examples, the slide rail 6 on the surface of the base frame 2 and the inner side of the guide frame 4-1 is connected to the bottom of the column 4-2 via a threaded connection, which further improves the stability and accuracy of the horizontal movement of the column 4-2. The slide rail 6 provides a clear movement path for the column 4-2, while the threaded connection enhances the tightness of the connection between the column 4-2 and the slide rail 6, preventing the column 4-2 from shaking or shifting during sliding. At the same time, the threaded connection facilitates the disassembly and maintenance of the column 4-2. When the slide rail 6 or the column 4-2 becomes worn, the parts can be replaced individually, reducing maintenance costs and ensuring the long-term stability of the horizontal adjustment function of the positioning component 4.

[0036] For example, such as Figure 2 As shown, the column 4-2 is vertically connected to the base frame 2, and one end of the support bolt 4-4 is provided with an anti-slip block 7.

[0037] In some examples, the column 4-2 is vertically connected to the base frame 2, ensuring that the column 4-2 always remains vertical. This provides stable support for the vertical lifting and lowering of the positioner body 3 and prevents deviations in the height adjustment of the positioner body 3 due to the tilting of the column 4-2. The anti-slip block 7 at one end of the support bolt 4-4 increases the friction between the support bolt 4-4 and the outer surface of the guide frame 4-1. When the support bolt 4-4 is tightened to lock the position of the column 4-2, the anti-slip block 7 prevents the support bolt 4-4 from slipping, ensuring that the horizontal position of the column 4-2 is firmly locked. This prevents the column 4-2 from shifting due to vibration during the operation of the positioner and ensures positioning accuracy.

[0038] For example, such as Figure 1As shown, the clamping plate 5-3 has a frosted anti-slip structure on both opposite surfaces.

[0039] In some examples, the frosted, anti-slip surface of the clamping plate 5-3 significantly enhances the friction between the clamping plate 5-3 and the equipment mounting structure. When the fixing assembly 5 is tightened to clamp the equipment, the frosted surface fits tightly against the equipment surface, preventing relative slippage between the clamping plate 5-3 and the equipment, further improving the stability of the base frame 2. Simultaneously, the frosted surface also reduces damage to the equipment surface, preventing indentations or scratches caused by rigid clamping, thus protecting the equipment's appearance while ensuring effective fixation.

[0040] In actual use: Place the base frame 2 in the designated position of the assembly fixture, rotate the fastening stud 5-2 in the rectangular slot 5-1, and the clamping plate 5-3 slides along the inner frame 5-4 close to the fixture, with the frosted anti-slip surface adhering to the fixture to complete the fixation. Loosen the support bolt 4-4 on the stabilizing frame 4-3, and push the column 4-2 to slide horizontally along the guide frame 4-1 and slide rail 6. After adjusting to the target lateral position, tighten the support bolt 4-4 and lock it with the anti-slip block 7. The electric drive screw 4-5 in the column 4-2 rotates, driving the positioner body 3 to rise and fall vertically. The infrared distance sensor 4-7 and the reflector block 4-6 work together to calibrate the height, ensuring accurate positioning. After positioning, the positioner body 3 assists in positioning the fixture components, requiring no manual operation throughout the process, achieving stable and accurate assembly positioning.
