Description

Technical Field

[0001] This utility model relates to the field of mechanical structure and tooling design technology, and in particular to a semi-automatic insertion and removal eccentricity adaptive correction tooling for a shaft. Background Technology

[0002] In the quality verification process before product shipment, repeated insertion and removal stability accuracy testing is a crucial task. Currently, some products employ manual insertion and removal verification. Manual insertion and removal verification offers flexibility, allowing operators to observe and adjust the process in real time based on actual conditions. When slight misalignment or angular deviations occur between the product and tooling, operators can use their experience to make corrections, ensuring smooth insertion and removal operations and thus verifying the product's stability accuracy. This verification method, to a certain extent, meets the basic verification requirements before product shipment, providing a degree of assurance for product quality.

[0003] However, new problems have arisen when using robotic arms or linear guide motors for automated testing. Due to the presence of installation and processing errors in the mechanical platform, the product is prone to eccentricity and misalignment with the tooling during horizontal insertion and removal movements. At the same time, improving processing and installation accuracy is difficult and costly in practice. Utility Model Content

[0004] The purpose of this utility model is to provide a semi-automatic insertion and removal eccentricity adaptive correction fixture for insert shafts, which aims to solve new problems that have arisen in the existing technology when using robotic arms or linear guide motors for automated testing. Due to the existence of mechanical platform installation and processing errors, eccentricity deviation between the product and the fixture is very likely to occur during the horizontal insertion and removal movement of the product. At the same time, improving processing accuracy and installation accuracy faces great difficulties in actual operation and is too costly.

[0005] To achieve the above objectives, this utility model employs a semi-automatic insertion and removal eccentricity adaptive correction fixture for a shaft, comprising a shaft verification tube, a fixed bracket, and a fixed base plate. A fixed plate is mounted on the fixed bracket, and a limit seat is mounted on the fixed bracket. A lead screw is rotatably mounted on the limit seat via a stepper motor. A shaft threaded sleeve is threaded onto the lead screw, and a fixing component is mounted on the shaft threaded sleeve. The shaft verification tube is fixedly connected to the fixed bracket and located at one end of the fixed bracket. The fixed bracket is fixedly connected to the fixed base plate and located on the fixed base plate.

[0006] The lead screw is connected to the output end of the stepper motor via a coupling.

[0007] The threaded sleeve of the insert shaft is provided with a sliding seat below it, and the limiting seat is provided with a sliding guide rail, and the sliding seat is slidably disposed on the sliding guide rail.

[0008] The fixing component is a fixing cover, and the two ends of the fixing cover are fixed to the threaded sleeve of the insertion shaft by screws.

[0009] An RCC compensator is provided between the insertion shaft verification tube and the fixed bracket. The end of the insertion shaft verification tube away from the RCC compensator has a tube opening adapted to the insertion shaft product, and the tube opening has a tapered chamfer.

[0010] This utility model discloses a semi-automatic insertion and extraction eccentricity adaptive correction fixture for insert shafts. The design utilizes a stepper motor to drive a lead screw to rotate, thereby causing the insert shaft threaded sleeve to move linearly along the lead screw, achieving precise reciprocating insertion and extraction of the insert shaft product. The cooperation between the sliding seat and the sliding guide rail ensures the stability of the insert shaft threaded sleeve's movement. The fixing cover is tightly fixed to the insert shaft threaded sleeve with screws, locking the insert shaft product. Specifically, the RCC compensator installed between the insert shaft verification tube and the fixed bracket can adaptively compensate for eccentricity offset between the product and the fixture. Combined with the tapered chamfer design of the insert shaft verification tube opening, it effectively guides the insert shaft product in an eccentric state to insert smoothly, avoiding problems such as jamming, severe friction, and product deformation caused by eccentricity. Thus, high-precision insertion and extraction verification is achieved at low cost. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1 to 5 This utility model provides a semi-automatic insertion and removal eccentricity adaptive correction fixture for a shaft, including a shaft verification tube 1, a fixed bracket 2, and a fixed base plate 3. A fixed plate 4 is provided on the fixed bracket 2, and a limit seat 5 is provided on the fixed bracket 2. A lead screw 7 is rotatably provided on the limit seat 5 via a stepper motor 6. A shaft threaded sleeve 8 is threaded on the lead screw 7, and a fixing component is provided on the shaft threaded sleeve 8. The shaft verification tube 1 is fixedly connected to the fixed bracket 2 and is located at one end of the fixed bracket 2. The fixed bracket 2 is fixedly connected to the fixed base plate 3 and is located on the fixed base plate 3.

[0020] In this embodiment, the insertion shaft verification tube 1, the fixed bracket 2, and the fixed base plate 3 constitute the basic framework of the tooling, providing a stable support structure for the entire insertion and removal verification process. The fixed plate 4 and the limiting seat 5 set on the fixed bracket 2, together with the lead screw 7 driven by the stepper motor 6, realize the precise linear movement of the insertion shaft product, effectively solving the problem of eccentric offset caused by mechanical platform installation and processing errors. At the same time, the fixed base plate 3 ensures the stability of the overall structure, making the verification process more reliable.

[0021] Furthermore, the lead screw 7 is connected to the output end of the stepper motor 6 via a coupling 9.

[0022] In this embodiment, the coupling 9 can effectively transmit motor torque while reducing the impact of assembly errors or minor offsets during operation on transmission accuracy, thus ensuring the accuracy and consistency of the insert shaft product during reciprocating insertion and extraction.

[0023] Furthermore, a sliding seat 10 is provided below the threaded sleeve 8, and a sliding guide rail 11 is provided on the limiting seat 5, with the sliding seat 10 slidably disposed on the sliding guide rail 11.

[0024] In this embodiment, this design not only enhances the smoothness of the movement of the threaded sleeve 8 and reduces motion deviation caused by friction or vibration, but also improves the durability and service life of the entire tooling, ensuring stability and reliability during long-term verification.

[0025] Furthermore, the fixing member is a fixing cover 12, and the two ends of the fixing cover 12 are fixed to the threaded sleeve 8 of the insert shaft by screws.

[0026] In this embodiment, this structure simplifies the installation and disassembly process of the insert shaft product and improves operational efficiency.

[0027] Furthermore, an RCC compensator 13 is provided between the insertion shaft verification tube 1 and the fixed bracket 2. The end of the insertion shaft verification tube 1 away from the RCC compensator 13 has a tube opening 14 adapted to the insertion shaft product, and the tube opening 14 has a tapered chamfer.

[0028] In this embodiment, the RCC compensator 13 is a 9116 series. The 9116 series compensation device includes an anodized aluminum top plate and bottom plate, a hardened steel overload pin, and shear columns; the 000 and 100 series use 3 shear columns; the 200 series uses 3 or 6 shear columns; the 400 series uses 6 or 12 shear columns. The locking function includes a cylinder, a load-bearing plate, a locking screw, and a locking screw bushing. The locking detection function also requires a sensor mounting hole and a proximity sensor with a cable. The 9116 series 000, 100, 200, and 400 size compensation devices have two options for matching assembly robots; the device can be installed using the threaded holes on the robot side mounting plate (top plate) or bolted from the robot side mounting plate (top plate) to the robot or assembly machine; tools The side mounting plates (base plates) are installed in two similar ways. All devices have two locating pins on both the robot-side mounting plate (top plate) and the tool-side mounting plate (base plate), and compliance compensation is limited by three overload protection pins. When the device reaches maximum compensation, the overload protection pins bear the load to prevent damage to the shear column. The RCC compensator 13 is designed to provide compliance compensation in translation, tilt, axial and torsional directions. Its projected (remote) compliance center: the compliance center (C-of-C) is a point in space where a single contact force will cause the compensator to translate without any rotation, and torque will produce rotation without any translation. When the insertion contact point approaches C-of-C, the axis of the inserted component will be aligned with the fixed axis during assembly. And all components of the RCC compensator 13 are contained within the outer diameter of the entire device.

[0029] In this embodiment, the RCC compensator 13 can adaptively compensate for the eccentricity between the product and the tooling, ensuring that the insert shaft product can be smoothly inserted into the verification tube. At the same time, the tapered chamfer design of the tube opening 14 of the insert shaft verification tube 1 further guides the insert shaft product in an eccentric state to be smoothly inserted, avoiding problems such as jamming, severe friction and product deformation caused by eccentricity, significantly improving the success rate and efficiency of the verification process and reducing the verification cost.

[0030] In this invention, the fixed base plate 3 is securely installed on the workbench, providing a stable foundation for the entire fixture. Then, the insertion shaft verification tube 1 is vertically suspended above the fixed base plate 3 via the fixed bracket 2, ensuring that the RCC compensator 13 is correctly installed between them to achieve eccentric adaptive compensation. Next, the insertion shaft product to be verified is placed inside the fixed cover 12 on the insertion shaft threaded sleeve 8, and the fixed cover 12 is tightly fixed to the insertion shaft threaded sleeve 8 using screws to ensure the insertion shaft product remains stable. Afterwards, the stepper motor 6 is controlled to rotate, via the... The coupling 9 drives the lead screw 7 to rotate, which in turn drives the insert shaft threaded sleeve 8 to move linearly along the sliding guide rail 11, causing the insert shaft product to be inserted and removed towards the insert shaft verification tube 1. During the insertion and removal process, if eccentricity occurs due to installation or processing errors, the RCC compensator 13 will automatically adjust the position of the insert shaft verification tube 1, and with the tapered chamfer design of its tube opening 14, guide the eccentric insert shaft product to be smoothly inserted, avoiding jamming or damage. Finally, when the number of insertions and removals reaches the preset value, the motor stops running, the verified insert shaft product is taken out, and one verification process is completed.

[0031] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
