Description

Technical Field

[0001] This utility model relates to the field of press-fitting fixture technology, and in particular to a metal parts assembly press-fitting fixture. Background Technology

[0002] Metal part assembly press-fit fixtures are key tools used for the processing and assembly of metal parts. They mainly consist of an upper press-fit structure and a bottom clamp. Through clever design, the bottom clamp can be quickly disassembled and replaced, flexibly adapting to different bases, and accurately and efficiently meeting the press-fitting needs of various metal parts with different shapes and sizes.

[0003] In the field of metal parts processing and assembly, press fitting is an extremely common and critical process. With the rapid development of the manufacturing industry and the continuous improvement of product diversification requirements, the types of metal parts are becoming increasingly complex, with significant differences in shape, size and structural characteristics.

[0004] Traditional metal part pressing fixtures typically employ a fixed base design. This single-structure fixture exhibits significant limitations when faced with various metal part pressing tasks. When different metal parts need to be processed, the inflexible base necessitates the redesign and manufacture of entirely new pressing fixtures. This not only leads to a substantial increase in equipment costs but also significantly extends the production cycle, severely impacting production efficiency and the company's market responsiveness. Furthermore, frequent replacement of the entire pressing fixture involves complex installation and debugging processes, which can easily introduce human error, reducing the consistency and reliability of product quality.

[0028] Example

[0029] like Figure 1-4 As shown, this utility model provides a technical solution: the top of the pressing platform 1 has two mounting sliding grooves 2, which provide a precise sliding track for the mounting slider 5 of the clamp base structure, ensuring the stable movement and positioning of the clamp base in the horizontal direction. The outer sides of the two mounting sliding grooves 2 are provided with auxiliary sliding grooves 3. The auxiliary sliding grooves 3 help to further stabilize the mounting slider 5 and provide space for the sliding of the limiting fixing block 6. The outer sides of the two auxiliary sliding grooves 3 and inside the pressing platform 1 are provided with quick-release limiting components, which are cleverly arranged in key positions inside the pressing platform 1 and can effectively act on the clamp base structure. The clamp base structure is located inside the two auxiliary sliding grooves 3 and the mounting sliding grooves 2. The clamp platform 4 of the clamp base structure serves as the base platform for carrying metal parts for pressing operations. The two mounting sliders 5 and the two limiting fixing blocks 6 at the bottom of the clamp platform 4 cooperate with the corresponding mounting sliding grooves 2 and auxiliary sliding grooves 3 to form a stable and quick-release connection system. The two quick-release limiting components can quickly fix and quickly disassemble the clamp base structure, achieving efficient assembly and disassembly functions through specific mechanical structures and interaction forces.

[0030] The mounting slider 5 slides within the mounting sliding groove 2 to ensure the accuracy of the horizontal displacement of the fixture base structure. The limiting fixing block 6 slides within the auxiliary sliding groove 3 and cooperates with the quick-release limiting component. When the fixture base structure is installed in place, the limiting fixing block 6 triggers the quick-release limiting component, achieving fixation under the action of spring force and mechanical structure. When disassembly is required, the spring force is overcome by pulling the rod 76, etc., causing the snap-fit ​​inclined block 72 to disengage from the limiting fixing block 6, thereby achieving quick disassembly.

[0031] The quick-release limiting assembly includes a snap-fit ​​wedge 72, a connecting rod 73, a compression spring 74, a pulling block 75, a pulling rod 76, and a mounting column 71. The mounting column 71 serves as the main frame of the entire quick-release limiting assembly, housing the snap-fit ​​wedge 72. The snap-fit ​​wedge 72 is designed as a block structure with a specific tilt angle, and its tilted surface is used to contact the limiting fixing block 6 to generate snap-fit ​​or disengagement. A connecting rod 73 is provided at the connection point of the snap-fit ​​wedge 72. The connecting rod 73 is a rigid connector that connects the snap-fit ​​wedge 72 and the pulling block 75, enabling their movements to be correlated. A compression spring 74 is sleeved on the connecting rod 73. Based on its elastic deformation characteristics, the compression spring 74 initially provides the snap-fit ​​wedge 72 with an angle towards the mounting column 71. The internal thrust keeps the snap-fit ​​block 72 in a position where it can snap into the limiting and fixing block 6. One end of the compression spring 74 is fixed to the snap-fit ​​block 72, and the other end is fixed to the mounting column 71, ensuring the stable transmission and action of the spring force. A pull block 75 is provided at the connection point of the connecting rod 73 and on the outside of the mounting column 71. The pull block 75 serves as the force point for external operation, making it convenient for the operator to apply external force. A pull rod 76 is provided at the connection point of the pull block 75, which extends to the outside of the pressing platform 1. The operator can drive the pull block 75 to move through the pull rod 76, thereby indirectly controlling the position of the snap-fit ​​block 72. The connecting rod 73 passes through the mounting column 71 and connects with the pull block 75, making the force transmission of the entire mechanical structure smoother and more stable.

[0032] Under normal conditions, the spring force of the compression spring 74 pushes the snap-fit ​​block 72, causing it to protrude a certain distance from the mounting column 71. When the limiting fixing block 6 of the clamp base structure is inserted into the auxiliary sliding groove 3 and contacts the inclined surface of the snap-fit ​​block 72, as the limiting fixing block 6 continues to be inserted, the snap-fit ​​block 72 overcomes the spring force and retracts into the mounting column 71 under the compression of the limiting fixing block 6. When the limiting fixing block 6 has completely passed through the snap-fit ​​block 72, the snap-fit ​​block 72 rebounds under the action of the spring force, locking the limiting fixing block 6 and achieving fixation. When disassembly is required, the pulling rod 76 is pulled, and the snap-fit ​​block 72 is driven to overcome the spring force and retract through the pulling block 75 and the connecting rod 73, so that the limiting fixing block 6 can be smoothly pulled out from the auxiliary sliding groove 3, completing the disassembly.

[0033] The bottom of the clamping platform 4 is provided with two mounting sliders 5. The mounting sliders 5 have a shape and size that match the mounting sliding groove 2. They are usually cuboid in shape and have a smooth surface to reduce sliding friction resistance and ensure smooth sliding within the mounting sliding groove 2. Each mounting slider 5 is equipped with a limiting fixing block 6. The shape of the limiting fixing block 6 is adapted to the auxiliary sliding groove 3, and one side of it has a locking surface that cooperates with the locking inclined block 72. This locking surface can be a plane or a curved surface with a certain curvature to form a stable locking with the locking inclined block 72. The fixture platform 4 is connected to two auxiliary sliding grooves 3 via two mounting sliders 5, and two limiting fixing blocks 6 are inserted and slid within the two auxiliary sliding grooves 3. This dual sliding and snap-fit ​​structure design allows the fixture base structure to be quickly positioned and stably fixed during installation, and can be quickly pulled out after the snap-fit ​​relationship is released during disassembly. The limiting fixing blocks 6 and the snap-fit ​​inclined blocks 72 work together, and their shapes, sizes and relative positions are precisely designed to ensure reliability and efficiency during fixing and disassembly.

[0034] Based on the sliding cooperation between the mounting slider 5 and the mounting sliding groove 2, the limiting fixing block 6 and the auxiliary sliding groove 3, and the snap-fit ​​principle between the limiting fixing block 6 and the snap-fit ​​inclined block 72, the fixture base structure can be quickly assembled and disassembled on the pressing platform 1. During installation, it relies on the sliding guidance of the slider and the groove, combined with snap-fit ​​fixation; during disassembly, it is pulled out by sliding after the snap-fit ​​is released.

[0035] A mounting base 8 is installed on the back side of the pressing platform 1. The mounting base 8 serves as the foundation for the drive motor 9, possessing sufficient strength and stability to withstand the vibration and reaction force generated by the drive motor 9 during operation. The drive motor 9 is located on the top of the mounting base 8. As a power source, the drive motor 9 converts electrical energy into mechanical energy. Its output end is equipped with a lead screw 10, which the drive motor 9 drives to rotate. The bottom of the lead screw 10 is connected to the pressing platform 1 via a bearing. The bearing's function is to reduce the frictional resistance during the rotation of the lead screw 10 and ensure... The lead screw 10 rotates stably in the vertical direction, connecting it to the pressing platform 1. This allows the rotation of the lead screw 10 to drive subsequent components to move vertically. A movable seat 12 is also mounted on the lead screw 10, connected to it via a threaded connection. When the lead screw 10 rotates, according to the threaded transmission principle, the movable seat 12 moves vertically along the lead screw 10. Linear optical shafts 11 are provided on both sides of the movable seat 12, providing precise guidance for its vertical movement and ensuring smooth operation. The linearity and stability of the seat 12 in the vertical direction are ensured to prevent it from shifting or wobbling. Two linear optical axes 11 pass through the movable seat 12, and the top is connected to the fixed seat 8, while the bottom is connected to the pressing platform 1, further enhancing the stability and reliability of the entire structure. A pressing seat 13 is provided on the front of the movable seat 12. The pressing seat 13 serves as an intermediate component connecting the pressing rod 17 and the movable seat 12, transmitting pressure and fixing the pressing rod 17. A quick-release retaining ring 14 is provided at the bottom of the pressing seat 13. The quick-release retaining ring 14 is designed for easy... The press-fit rod 17 can be quickly replaced and adjusted. The quick-release retaining ring 14 has two through holes 15, which can be used to install fasteners or perform other auxiliary operations. The quick-release retaining ring 14 has a quick-fixing component 16 inside. The quick-fixing component 16 can quickly fix the press-fit rod 17 in the quick-release retaining ring 14 or remove it from it. The bottom of the quick-fixing component 16 has a press-fit rod 17. As a component that directly contacts the metal part and applies pressure, the shape, size and material of the press-fit rod 17 are selected and designed according to the press-fit requirements of different metal parts.

[0036] The drive motor 9 drives the lead screw 10 to rotate, and the moving seat 12 moves up and down along the lead screw 10 using thread transmission. The linear optical axis 11 ensures the accuracy of the moving direction of the moving seat 12. The quick-release fixing ring 14 cooperates with the quick-fixing part 16 to realize the quick replacement of the pressing rod 17 to adapt to the pressing requirements of different metal parts.

[0037] In summary, during use, firstly, select a suitable fixture base structure according to the type of metal part to be pressed. Align the mounting slider 5 at the bottom of the fixture platform 4 with the mounting sliding groove 2 of the pressing platform 1, and align the limiting fixing block 6 with the auxiliary sliding groove 3. Then, insert the fixture base structure. During insertion, the limiting fixing block 6 contacts the snap-fit ​​inclined block 72 of the quick-release limiting component, causing the snap-fit ​​inclined block 72 to retract. After the limiting fixing block 6 has completely passed through, the snap-fit ​​inclined block 72 pops out under the action of the compression spring 74 to lock the limiting fixing block 6, completing the quick installation and fixing of the fixture base structure. Next, select a suitable pressing method according to the pressing requirements. The rod 17 is installed at the bottom of the pressing base 13 via the quick-release retaining ring 14 and quick-release fastener 16. The drive motor 9 on the fixed base 8 is started, and the drive motor 9 drives the lead screw 10 to rotate, causing the moving base 12 to move downward along the lead screw 10 under the guidance of the linear optical axis 11. The pressing rod 17 at the bottom of the pressing base 13 moves downward accordingly, performing a pressing operation on the metal parts placed on the fixture platform 4. When it is necessary to change the fixture base structure to adapt to different metal parts, pull the pull rod 76 of the quick-release limit component to retract the locking wedge 72, remove the fixture base structure, and then repeat the above installation steps.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
