In the description created by the present application, unless otherwise specified, "multiple" means two or more.

[0049] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0050] like Figure 1-Figure 7As shown, a preferred embodiment of the present application provides a positioning and clamping mechanism for screw assembly, including a tooling seat 100, a pressing assembly 200 and a positioning assembly 300, wherein a first accommodating groove 110 is opened on one side of the tooling seat 100 for accommodating a workpiece, and the pressing assembly 200 is connected to the tooling seat 100. The pressing assembly 200 includes a pressing block 210, and the pressing block 210 moves in a controlled manner. When the positioning and clamping mechanism is in a working state, the pressing block 210 abuts against the workpiece placed in the first accommodating groove 110, thereby confining the workpiece in the first accommodating groove 110. The positioning assembly 300 includes a positioning seat 310 and a rotating member 320, wherein the positioning seat 310 moves in a controlled manner, and when the positioning and clamping mechanism is in a working state, the positioning seat 310 abuts against the workpiece placed in the first accommodating groove 110 and is aligned with the screw hole on the workpiece, the rotating member 320 is connected to the positioning seat 310, and the rotating member 320 rotates in a controlled manner, one end of the rotating member 320 is constructed to be connectable to the end of the screw, and the end of the rotating member 320 that can be connected to the end of the screw is aligned with the screw hole of the workpiece placed in the first accommodating groove 110 when the positioning and clamping mechanism is in a working state.

[0051] In this embodiment, since a first accommodating groove 110 is opened on the tooling seat 100 for accommodating the workpiece, and the workpiece is stably confined in the first accommodating groove 110 through the controlled movement of the pressure block 210, the problem of unstable positioning and easy displacement of the workpiece in the prior art is effectively solved, thereby ensuring the stability of the workpiece during the assembly process. At the same time, the positioning seat 310 is precisely aligned with the screw hole of the workpiece, avoiding the inaccurate installation position of the screw and time-consuming recalibration problems in the prior art. In addition, the turning member 320 is linked to the positioning seat 310 and can be connected to the end of the screw, thereby achieving consistency in the installation of the screw and avoiding the problems of inconsistent torque applied during manual operation and differentiated installation quality.

[0052] Among them, the tooling seat 100 is the core structural part of this positioning and pressing mechanism, and its main function is to provide stable support and positioning for the workpiece. The first accommodating groove 110 opened on one side of the tooling seat 100 is specially designed to accommodate the workpiece to be processed and position the side of the workpiece to ensure the fixation and accuracy of the workpiece during the assembly process. The workpieces suitable for this tooling seat 100 are specifically shown in the figure. The material of the tooling seat 100 should have good mechanical strength and wear resistance to withstand the pressure and impact that may be generated during the assembly process. The shape of the first accommodating groove 110 should match the shape of the workpiece to ensure that the workpiece can fit tightly and avoid displacement during the pressing process. The processing accuracy of the tooling seat 100 directly affects the assembly quality of the workpiece. Therefore, the tolerance of the tooling seat 100 should be strictly controlled during manufacturing to ensure accurate docking with the positioning assembly 300 (such as the positioning seat 310). The tooling seat 100 should be set on a flat mounting surface to ensure that in the working state, the pressure block 210 is parallel to the abutment plane of the workpiece to ensure that the applied pressure is evenly distributed. The tooling base 100 should also be designed to be stably fixed to the tooling bracket 400 described later to prevent movement or tilting during operation, ensuring the reliability of the assembly process. Through the above design, the tooling base 100 will be able to effectively support the workpiece and work in conjunction with other components to achieve precise screw assembly.

[0053] In some embodiments, as Figure 2 As shown, a second accommodating groove 111 is provided on one inner wall of the first accommodating groove 110 of the tooling seat 100, and the positioning and clamping mechanism also includes a first sensor 500, which is arranged in the second accommodating groove 111. The controller is connected to the first sensor 500, the first cylinder 330 and the second cylinder 340 to receive the signal from the first sensor 500 and control the movement of the first mobile end and the movement of the second mobile end.

[0054] Among them, the first sensor 500 is mainly used to monitor the status of the workpiece in the second receiving groove 111. Its functions include real-time detection of the position of the workpiece and whether it meets the assembly requirements. The first sensor 500 usually adopts a photoelectric or proximity type, which can accurately identify the presence or absence of the workpiece, and transmits the monitoring signal to the controller. It provides necessary feedback information for the assembly process, thereby helping the system to adjust and ensure the accuracy and efficiency of the assembly. The controller is the core processing unit of the positioning and clamping mechanism, responsible for receiving the signal from the first sensor 500 and performing data processing. The controller analyzes the information fed back by the sensor to determine the status of the workpiece. According to the processing results, the controller sends instructions to the first cylinder 330 and the second cylinder 340 to adjust the position of its mobile end to ensure the precise positioning of the workpiece during the assembly process. The controller is also responsible for coordinating the operation of various components in the system to ensure the smoothness of the overall assembly process. The efficiency of the controller directly affects the accuracy and efficiency of the assembly process and is the key to achieving intelligent and automated assembly.

[0055] The pressing assembly 200 is responsible for firmly pressing the workpiece onto the fixture base 100 to ensure that its position does not shift during the assembly process. Its smooth movement and stability must be ensured during design.

[0056] The pressure block 210 is in direct contact with the workpiece and is responsible for applying pressure to fix the workpiece in the fixture 100. The shape of the pressure block 210 should match the contact surface of the workpiece to ensure that the contact area of ​​the workpiece can be fully covered to provide uniform pressing force. The pressure block 210 should be made of high-strength, wear-resistant materials to withstand long-term pressing operations without being easily deformed or damaged. The pressure block 210 should have good pressing stability and be able to ensure that it is parallel to the abutting surface of the workpiece when the positioning and clamping mechanism is in working condition to avoid unnecessary lateral pressure. In some embodiments, the pressure block 210 may need to have a certain degree of adjustability to adapt to the assembly requirements of different workpieces. Therefore, based on the above design, the pressure block 210 can effectively fix the workpiece firmly and ensure the required stability and precision during the screw assembly process.

[0057] In some embodiments, as Figure 3 As shown, the pressing assembly 200 also includes a guide rail 220, a slider 230, a connector 240 and a pressure rod 250, wherein the guide rail 220 is connected to the tooling seat 100, the slider 230 is slidably connected to the guide rail 220, the slider 230 is restricted to move toward or away from the tooling seat 100, and the sliding trajectory of the slider 230 is parallel to the installation plane, the connector 240 is fixedly connected to the slider 230, the pressure rod 250 is rotatably connected to the connector 240, and one end of the pressure rod 250 is connected to the pressure block 210 to drive the pressure block 210 to move, and the rotation plane of the pressure rod 250 is perpendicular to the installation plane.

[0058] The guide rail 220 is connected to the tooling seat 100 to provide guidance for the slider 230 and ensure that the slider 230 moves along the set trajectory. The material of the guide rail 220 should have good wear resistance to withstand the wear caused by repeated operations. The slider 230 is slidably connected to the guide rail 220 and is limited to moving in the direction toward or away from the tooling seat 100. The design of the slider 230 should ensure that its movement trajectory is parallel to the installation plane to ensure that the pressing force of the pressure block 210 is uniform. The connector 240 connects the slider 230 to the pressure rod 250 and is responsible for transmitting motion and force. The structure of the connector 240 should be simple and sturdy to ensure stability during the pressing process. One end of the pressure rod 250 is connected to the pressure block 210, and the pressure rod 250 rotates in a controlled manner, driving the pressure block 210 to move through its rotation. The rotation plane of the pressure rod 250 is perpendicular to the installation plane to ensure that the direction of the pressure applied to the workpiece is correct.

[0059] Positioning assembly 300 is a crucial component of the positioning and clamping mechanism, ensuring accurate positioning and alignment of the workpiece during assembly. This assembly is designed to enable efficient and reliable screw assembly. Specifically, its primary function is to align the workpiece's screw hole with the twisting element 320 during the clamping process, ensuring smooth screw insertion.

[0060] Positioning base 310 is the core component of positioning assembly 300, responsible for contacting the workpiece and providing stable support. Its controlled movement allows for adjustment to different working conditions and align with the screw holes on the workpiece. Positioning base 310 should be constructed of high-strength, wear-resistant materials to ensure structural stability and prevent deformation during extended use.

[0061] Twist 320 is another key component of positioning assembly 300, responsible for transmitting rotational motion to the screw. Twist 320 is connected to positioning base 310 and, in operation, aligns with the screw hole in the workpiece to ensure smooth screw insertion. Twist 320 should possess good rotational flexibility and stability to ensure smooth rotation when pressure is applied, preventing damage or misalignment of the screw. Specifically, twist 320 is embodied as a section with the same structure as a screwdriver head, allowing for proper use with the screw.

[0062] In some embodiments, the positioning seat 310 is provided with a through slot, the extension direction of the through slot is perpendicular to the installation plane described later, and the turning piece 320 is movably connected in the through slot so that the turning piece 320 can move along the extension direction of the through slot, and the end of the turning piece 320 facing the installation plane is configured to be magnetic to absorb the screw so that the end of the screw is connected to the end of the turning piece 320 facing the installation plane to ensure the accurate positioning of the screw end during the assembly process.

[0063] In some embodiments, as Figure 6As shown, the positioning assembly 300 further includes a first cylinder 330, a second cylinder 340, and a mounting base 350. The first cylinder 330 is fixedly connected to the tooling bracket 400, the first cylinder 330 includes a first movable end, and the moving direction of the first movable end is defined as a first direction. The second cylinder 340 is fixedly connected to the first movable end of the first cylinder 330 so that the second cylinder 340 moves synchronously with the first movable end of the first cylinder 330. The second cylinder 340 includes a second movable end, and the moving direction of the second movable end is defined as a second direction. The mounting base 350 is connected to the second movable end of the second cylinder 340, and the positioning base 310 is connected to the mounting base 350 so that the positioning base 310 moves with the second movable end. When the positioning and clamping mechanism is in working state, the second direction and the pressure block 210 are parallel to the abutment surface of the workpiece in the first accommodating groove 110, the first direction and the second direction are perpendicular, the first direction and the pressure block 210 are perpendicular to the abutment surface of the workpiece in the first accommodating groove 110, and both the first direction and the second direction are perpendicular to the moving direction of the slider 230.

[0064] Further, in some embodiments, Figure 1 and Figure 6 As shown, the positioning assembly 300 also includes a micro-motion mechanism 360, and the positioning seat 310 is connected to the second movable end of the second cylinder 340 through the micro-motion mechanism 360. The micro-motion mechanism 360 includes a fixed seat 361, an end seat 362 and a micro-motion seat 363. The fixed seat 361 is connected to the second movable end of the second cylinder 340 to move synchronously with the second movable end. The end seat 362 is installed on the side of the fixed seat 361 away from the second cylinder 340. The micro-motion seat 363 is movably connected to the end seat 362 so that the micro-motion seat 363 deflects relative to the end seat 362. The deflection plane of the micro-motion seat 363 is perpendicular to the installation plane. The micro-motion seat 363 is fixedly connected to the positioning seat 310. The fine-motion seat 363 is configured to abut against the end seat 362 when the positioning and clamping mechanism is in working state, so as to provide a holding force toward the workpiece for the positioning seat 310 through the mounting seat 350, so that one end of the positioning seat 310 facing the workpiece abuts against the side of the workpiece facing the positioning seat 310.

[0065] The micro-motion mechanism 360 is an important component in the positioning and clamping mechanism for finely adjusting the position of the positioning seat 310 relative to the workpiece. Its main function is to provide small and precise movements during the clamping and positioning process. The fixed seat 361 is connected to the second movable end of the second cylinder 340 to ensure that the micro-motion mechanism 360 moves with the second cylinder 340 in the working state. The end seat 362 is set on the side of the fixed seat 361 away from the second cylinder 340 and serves as the support part of the micro-motion mechanism 360. The micro-motion seat 363 is movably connected to the end seat 362 to allow relative deflection. The positioning seat 310 is fixedly connected to the micro-motion seat 363 to ensure that the positioning seat 310 can be fine-tuned under the action of the micro-motion seat 363.

[0066] The deflection plane of the fine-motion seat 363 is perpendicular to the mounting plane, enabling fine-tuning in a vertical direction and providing precise control. In operation, the fine-motion seat 363 abuts the end seat 362, providing a holding force toward the workpiece, thereby ensuring that the positioning seat 310 is precisely aligned with the workpiece. The fine-motion mechanism 360 enables the positioning seat 310 to be quickly positioned within a wide range before fine-tuning, ensuring precise alignment of the screw hole with the rotating member 320 and improving assembly accuracy.

[0067] In some embodiments, as Figure 6 As shown, the positioning assembly 300 also includes a pressure roller, which is rotatably connected to the positioning seat 310. The pressure roller is arranged on the side of the positioning seat 310 facing the installation plane, and when the positioning and clamping mechanism is in a working state, the outer peripheral side of the pressure roller abuts against the workpiece placed in the first accommodating groove 110 to limit the movement of the workpiece relative to the tooling seat 100.

[0068] The pressure roller is a key component in the positioning and clamping mechanism, primarily used to apply appropriate pressure to the workpiece during assembly to limit its movement relative to the workholding 100, ensuring stability and precision during assembly. The pressure roller is rotatably connected to the mounting plate, ensuring flexible rotation during assembly. The outer circumference of the pressure roller is designed to abut the workpiece and is typically made of a wear-resistant and resilient material to withstand prolonged use and reduce wear.

[0069] When the positioning and clamping mechanism is in operation, the outer circumference of the pressure roller abuts against the workpiece placed in the first receiving groove 110, thereby applying pressure to the workpiece and preventing it from moving during assembly. By applying uniform pressure to the workpiece, the pressure roller ensures that the workpiece remains stable during assembly and reduces displacement caused by vibration or external forces. By limiting the relative movement of the workpiece, the pressure roller helps ensure precise alignment of the screw hole and the rotating member 320, thereby improving assembly accuracy. The design of the pressure roller enables it to accommodate workpieces of varying sizes and shapes, increasing the versatility and flexibility of the assembly equipment.

[0070] In some embodiments, as Figure 1As shown, the positioning and clamping mechanism also includes a tooling bracket 400, which includes a mounting plane. The tooling seat 100 is arranged at the mounting plane, and when the positioning and clamping mechanism is in a working state, the contact plane between the pressure block 210 and the workpiece in the first receiving groove 110 is parallel to the mounting plane. The tooling bracket 400 is an important basic structure of the positioning and clamping mechanism, which is mainly used to support the tooling seat 100 and other components to ensure the stability and accuracy of the entire device in a working state. The tooling bracket 400 is usually made of a solid metal material and has sufficient strength and rigidity to withstand the force and vibration generated during operation. The mounting plane is a plane of the tooling bracket 400, which provides reliable support for the tooling seat 100, ensures that the contact plane between the pressure block 210 and the workpiece is parallel, and optimizes the working effect. In some embodiments, the bottom of the tooling bracket 400 is usually equipped with a non-slip foot pad or a fixing device to enhance the contact stability with the ground and prevent displacement during operation.
