Description

Technical Field

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 and Figure 3As shown, a watch case internal rotating loading and unloading cyclic clamping processing fixture includes a base 1, a fixing component 2 and a material tray gripping component 5 are arranged on the base 1, a first clamping mechanism 3 is arranged on both sides of the fixing component 2, and a second clamping mechanism 4 is arranged above the fixing component 2. The fixing component 2 includes a fixing platform 27, and a fixing area 22 composed of a fixed bearing edge 23 and a movable clamping edge 24 is arranged above the fixing platform 27. The first clamping mechanism 3 is provided with a rotating gripper 38, and the second clamping mechanism 4 is provided with a first gripper 48 and a second gripper 46. The material tray gripping component 5 includes a material tray gripping mechanism 52, a third cylinder 59 for driving the material tray gripping mechanism 52 to move left and right, and a fifth cylinder 53 for driving the material tray gripping mechanism 52 to move up and down. A loading bin material tray support plate 51 and a receiving bin material tray support plate 54 are arranged below the material tray gripping mechanism 52. The loading bin material tray support plate 51 is used to place... The fixture includes an interchangeable loading / unloading box 7, which has a loading tray area 71 and a receiving tray area 72. The base 1 serves as the basic support structure for the entire fixture, providing a stable mounting platform for other components such as the fixing component 2 and the tray gripping component 5. This ensures that each component maintains a relatively fixed position during operation, enabling the entire fixture to operate stably and withstand various forces and vibrations generated during processing. The fixed table 27 is the core load-bearing part of the fixing component 2, providing stable support for the fixing area 22 and ensuring that the watch case has a stable reference platform during processing. The fixed support edge 23 provides a fixed support surface for the watch case, determining the initial position of the watch case during processing. The movable clamping edge 24, driven by the first gripping finger cylinder 25, can move towards the fixed support edge 23 to clamp and fix the watch case, preventing it from moving or shaking during processing and ensuring processing accuracy. The pressure block 21 is fixed next to the fixing area 22 to further enhance the fixing effect on the watch case, preventing the watch case from tilting or shifting due to force during processing, and ensuring the stability of processing. The base block 28 is set in the middle of the fixing area 22 and may be used to assist in positioning the watch case or to provide specific support or reference points for certain processing steps, which helps to improve the accuracy and consistency of processing. The rotating downward pressure cylinder 26 is installed under the fixing table 27 and can apply downward pressure or perform rotation operation on the watch case as needed during processing to meet the needs of different processing techniques, such as when the watch case needs to be rotated or when additional pressure is needed to ensure processing quality. The transverse slide rail 31 provides a horizontal movement track for the transverse slide table 32. The first cylinder 33 drives the transverse slide table 32 to move horizontally on the transverse slide rail 31, so that the flipping gripper 38 can be adjusted in the horizontal direction to accurately grip and place the watch case. The longitudinal slide rail 34 provides a vertical track for the longitudinal slide table 35. The second cylinder 36 drives the longitudinal slide table 35 to move vertically on the longitudinal slide rail 34, allowing the flipping gripper 38 to adjust its height in the vertical direction to accommodate the gripping and placement needs of watch cases of different heights. The first clamping swing cylinder 37 can drive the flipping gripper 38 to swing, realizing the flipping operation of the watch case.During the watch case machining process, when different surfaces of the watch case need to be machined, the flipping jaw 38 can flip the watch case to a suitable angle, facilitating machining by the second clamping mechanism 4 or other machining equipment, thus improving machining flexibility and efficiency. The first jaw 48 and the second jaw 46 are used to clamp and fix the watch case during machining, cooperating with the first clamping mechanism 3 to ensure the stability and accuracy of the watch case during machining. The first jaw 48 and the second jaw 46 can be designed and adjusted according to the shape of the watch case and machining requirements to better adapt to the machining of different types of watch cases. The air intake mechanism 41 is used to provide specific gases (such as cooling gases, chip blowing gases, etc.) to the watch case machining area to ensure the smooth progress of the machining process and prevent the watch case from overheating or chip accumulation from affecting the machining quality; the air intake mechanism connection and separation device 42 is used to control the on / off and connection of the gas, flexibly controlling the gas supply according to machining needs. The second clamping swing cylinder 44 can drive the connected components above to swing. The tool holder 43 may be used to install machining tools to realize the machining operation of the watch case. The second gripping finger cylinder 47 and the third gripping finger cylinder 45 are connected to the first gripper 48 and the second gripper 46 respectively. Through the drive of the cylinder, the gripper can accurately clamp and release the watch case. At the same time, the swing function of the second clamping swing cylinder 44 can adjust the position of the machining tool or gripper to meet the needs of different machining processes. The tray gripping mechanism 52 is the core component for gripping and placing the tray. Through specific mechanical structures (such as clamps, suction cups, etc.), it realizes the gripping and releasing operations of the loading tray and the receiving tray to complete the loading and unloading tasks of the watch case. The third cylinder 59 drives the tray gripping mechanism 52 to move left and right in the horizontal direction, so that the tray gripping mechanism 52 can accurately reach the position of the loading bin and the receiving bin to grip the loading tray or place the machined watch case into the receiving tray. The fifth cylinder 53 drives the material tray gripping mechanism 52 to move up and down in the vertical direction, adjusting the height of the material tray gripping mechanism 52 so as to smoothly grip and place material trays of different heights, adapting to the interchangeable trial loading and unloading boxes 7 of different specifications; the loading bin material tray support plate 51 and the receiving bin material tray support are used to support the loading bin and the receiving bin respectively, providing a stable placement platform for the material trays, ensuring that the material trays will not shake or tilt during the loading and unloading process, and ensuring the accuracy and stability of loading and unloading; the interchangeable trial loading and unloading boxes 7 can be easily replaced, improving production efficiency; the loading bin area 71 is used to place the watch cases to be processed, and the receiving bin area 72 is used to collect the processed watch cases, realizing the centralized storage and orderly loading and unloading of watch cases, which facilitates production management and quality control.

[0022] like Figure 2As shown, a pressure block 21 is fixed next to the fixed area 22, a base block 28 is set in the middle of the fixed area 22, a first gripping finger cylinder 25 for driving the movable clamping edge 24 is set below the fixed area 22, and a rotating pressing cylinder 26 is installed under the fixed table 27. When the watch case is placed in the fixed area 22 for processing, the fixed bearing edge 23 and the movable clamping edge 24 alone cannot completely ensure the stability of the watch case. The pressure block 21 applies additional pressure to the watch case from the side or top, pressing the watch case tightly in the fixed area 22, preventing the watch case from tilting, shifting or shaking due to cutting forces, vibrations and other factors during processing, thereby ensuring the accuracy and quality of processing; the base block 28 can serve as an auxiliary positioning reference for the watch case in the fixed area 22. During the case placement process, specific parts of the case can contact the base block 28. The position and shape of the base block 28 determine the precise position of the case within the fixed area 22, ensuring consistent positional accuracy each time the case is placed, thus improving the repeatability and stability of the processing. The first gripping finger cylinder 25 is the power source for the movable clamping edge 24. Through the extension and retraction of the cylinder, the movable clamping edge 24 can be driven to move towards or away from the fixed bearing edge 23, achieving automatic clamping and release of the case. This automated operation improves production efficiency, reduces manual intervention, and lowers labor intensity. During the case processing, the rotating downward pressure cylinder 26 can apply downward pressure, further pressing the case into the fixed area 22, enhancing the case's fixation effect. Especially when performing processing operations requiring higher pressure, the rotating downward pressure cylinder 26 can provide sufficient pressure to ensure smooth processing.

[0023] like Figure 3As shown, the first clamping mechanism 3 also includes a transverse slide rail 31 mounted on the base 1. A transverse slide table 32 and a first cylinder 33 for driving the transverse slide table 32 are mounted on the transverse slide rail 31. A longitudinal slide rail 34 is mounted on the transverse slide table 32. A longitudinal slide table 35 and a second cylinder 36 for driving the longitudinal slide table 35 are mounted on the longitudinal slide rail 34. A first clamping swing cylinder 37 is mounted above the longitudinal slide table 35 and is fixedly connected to the flipping gripper 38. The transverse slide rail 31 provides a stable horizontal movement track for the transverse slide table 32, ensuring that the transverse slide table 32 can move smoothly along a predetermined straight direction. The first cylinder 33, as a power source, precisely drives the transverse slide table 32 to move on the transverse slide rail 31 through its telescopic movement, thereby driving the entire longitudinal movement assembly and the flipping gripper 38 to adjust their positions in the horizontal direction. This precise horizontal positioning capability allows the flipping gripper 38 to accurately reach the gripping and placement position of the watch case, adapting to the processing needs of watch cases in different positions and improving the accuracy and efficiency of loading and unloading. During the production process, the placement position of the watch case may vary due to factors such as production process and equipment layout. The combined design of the transverse slide rail 31 and the transverse slide table 32 allows the first clamping mechanism 3 to flexibly respond to these changes. By adjusting the position of the transverse slide table 32, the flipping gripper 38 can cover a large horizontal working area, meeting the gripping and placement requirements under different workpiece layouts and enhancing the versatility and adaptability of the fixture. The longitudinal slide rail 34 is mounted on the transverse slide table 32, providing a vertical movement track for the longitudinal slide table 35. The second cylinder 36 drives the longitudinal slide table 35 to move vertically up and down on the longitudinal slide rail 34, thereby driving the first clamping swing cylinder 37 and the flipping gripper 38 to adjust their height in the vertical direction. This vertical movement function allows the flipping gripper 38 to adapt to the gripping and placement of watch cases at different heights. Whether gripping a watch case from a higher loading bin or placing a finished watch case into a lower receiving bin, it can accurately complete the action, ensuring the smooth progress of the loading and unloading process. During the watch case processing, different processing steps may have different requirements for the height of the watch case. The design of the longitudinal slide rail 34 and the longitudinal slide table 35 allows the flipping gripper 38 to be precisely adjusted in the vertical direction according to specific processing requirements, accurately placing the watch case at the specified height position of the processing equipment, ensuring the accuracy and quality of processing. The first clamping swing cylinder 37 is fixedly connected to the flipping gripper 38, and it can drive the flipping gripper 38 to swing at a certain angle. During the watch case processing, when different surfaces of the watch case need to be processed, the first clamping swing cylinder 37 can control the flipping jaw 38 to flip the watch case to a suitable angle so that the surface to be processed faces the processing equipment. This eliminates the need for manual flipping of the watch case, greatly improving the flexibility and efficiency of the processing. The flipping jaw 38 is the component that directly contacts the watch case. It uses a specific mechanical structure (such as a clamp, suction cup, etc.) to perform the gripping and releasing operations on the watch case.In terms of design, the flip-over jaws 38 are optimized according to the shape, size, and material of the watch case to ensure a firm grip during handling, preventing the case from falling during movement or flipping. When releasing the case, they accurately and smoothly place it in the designated position, ensuring stability and accuracy during loading and unloading. To prevent damage to the case during handling and flipping, the surface of the flip-over jaws 38 is typically wrapped with a soft, wear-resistant material or designed with a special cushioning structure. This reduces friction and collision between the jaws and the watch case, preventing scratches or damage to the case surface and ensuring the quality of the watch case's processing.

[0024] like Figure 4As shown, the second clamping mechanism 4 also includes an air intake mechanism 41 and an air intake mechanism connection / disconnection device 42. The air intake mechanism connection / disconnection device 42 is connected to the second clamping swing cylinder 44. A knife handle 43 is provided above the second clamping swing cylinder 44, and a second gripping finger cylinder 47 is connected below the second clamping swing cylinder 44. The second gripping finger cylinder 47 is connected to the first gripper 48, and a third gripping finger cylinder 45 is connected to one side of the second clamping swing cylinder 44. The third gripping finger cylinder 45 is connected to the second gripper 46. The air intake mechanism 41 is the power source of the entire second clamping mechanism 4. It provides compressed air to pneumatic components such as cylinders, enabling the piston of the cylinder to perform reciprocating linear motion, thereby providing power support for various actions of the clamping mechanism. By controlling the on / off state and air intake volume of the air intake mechanism 41, the action sequence, speed, and force of each cylinder in the second clamping mechanism 4 can be precisely controlled. Adjusting the air intake volume changes the clamping and releasing speeds of the second gripping finger cylinder 47 and the third gripping finger cylinder 45, ensuring that the watch case is not damaged by excessive impact during gripping and placement. The air intake mechanism connection and separation device 42 enables quick connection and separation between the air intake mechanism and the second clamping swing cylinder 44. When it is necessary to replace the clamping mechanism or perform maintenance, this device can be used to easily disconnect the air intake mechanism from the cylinder, improving the maintainability and flexibility of the equipment. In the connected state, the air intake mechanism connection and separation device 42 ensures the airtightness between the air intake mechanism and the second clamping swing cylinder 44, preventing compressed air leakage and ensuring that the cylinder can work normally. Poor airtightness will lead to insufficient cylinder pressure, affecting the action accuracy and stability of the clamping mechanism. The second clamping swing cylinder 44 can drive the upper handle 43 and the lower second gripping finger cylinder 47 to swing at a certain angle. During the watch case machining process, when different surfaces of the watch case need to be machined, the second clamping swing cylinder 44 can swing the watch case to a suitable angle, so that the surface to be machined faces the machining equipment, eliminating the need for manual flipping of the watch case and improving the flexibility and efficiency of the machining process. The second clamping swing cylinder 44 works in conjunction with the air intake mechanism 41, the second gripping finger cylinder 47, and other components to complete complex actions such as gripping, flipping, and placing the watch case. For example, when gripping the watch case, the second gripping finger cylinder 47 first clamps the watch case, and then the second clamping swing cylinder 44 swings at a certain angle to move the watch case to the designated position for machining. The tool holder 43 is installed above the second clamping swing cylinder 44. It acts as a connecting bridge between the cylinder and the machining tool, and can transmit the swinging motion of the cylinder to the tool or positioning component. At the same time, the tool holder 43 achieves precise positioning with the tool or positioning component through a precise structural design, ensuring the positional accuracy of the tool or positioning component during the swinging process, thereby improving the machining accuracy of the watch case.

[0025] like Figure 5 and Figure 6As shown, a third slide rail 516 is provided above the material tray gripping mechanism 52, and a third cylinder 59 for driving the material tray gripping mechanism 52 to move left and right and a fourth cylinder 58 for driving the material tray gripping mechanism 52 to move back and forth are also provided below the material tray gripping mechanism 52. A drag chain 510 is provided below the third cylinder 59. The third slide rail 516 provides a stable motion track for the material tray gripping mechanism 52, ensuring that the material tray gripping mechanism 52 can move accurately along a predetermined straight line during movement, reducing deviation and shaking. The length and bending radius of the drag chain 510 can limit the range of motion of the material tray gripping mechanism 52, preventing damage to the air pipes and cables due to excessive extension or bending during movement.

[0026] like Figure 5 As shown, a feeding hopper tray support frame 55 is provided around the feeding hopper tray support plate 51. A material box positioning and locking mechanism 56 is provided on the feeding hopper tray support frame 55, and a material box left and right movement proximity sensor 57 is provided on the side wall of the feeding hopper tray support frame 55. The feeding hopper tray support frame 55 provides a stable frame structure for the tray support plate, ensuring that the tray support plate can bear the weight of the tray and the material it contains, and remain stable during equipment operation. It will not tilt, shake, or deform due to the weight of the tray or equipment vibration, thereby ensuring the accurate position and stable placement of the tray in the feeding hopper. The support frame defines the boundary of the feeding hopper, confining the tray within a specific space, preventing the tray from sliding out of the feeding hopper during movement or feeding, avoiding equipment failure or production accidents caused by abnormal tray position, and also facilitating the management and maintenance of the feeding hopper. In automated production, the material box needs to be accurately placed in the designated position of the feeding hopper to ensure that subsequent gripping and feeding operations can be carried out smoothly. The material bin positioning and locking mechanism 56, through specific mechanical structures (such as positioning pins and positioning blocks) and locking devices (such as cylinder-driven locking clamps), can precisely fix the material bin in a predetermined position, ensuring that the positional accuracy of the material bin meets production requirements and preventing material failure or damage due to material bin position deviation. During equipment operation, the material bin will be subjected to external forces such as vibration and impact, resulting in movement or shaking. The material bin positioning and locking mechanism 56 can firmly lock the material bin in the feeding bin, preventing it from shifting during equipment operation and ensuring that the tray is always in the correct position, guaranteeing the stability and reliability of feeding. The tray left and right movement proximity sensor 57 can detect the left and right movement position of the tray in the feeding bin in real time and feed the detected signal back to the control system. Based on these signals, the control system can accurately grasp the movement status and position information of the tray, thereby achieving precise control of the tray movement and ensuring that the tray can accurately move to the designated feeding position.

[0027] like Figure 5 and Figure 7As shown, upper and lower limit cylinders 511 for the picking bin and 514 for the receiving bin are respectively installed on both sides below the material tray support frame 55 of the feeding hopper. Upper and lower limit cylinders 512 for the picking bin and 513 for the receiving bin are installed below the material tray support plate 51 of the feeding hopper. The main function of the upper and lower limit cylinders 511 and 514 is to limit the vertical movement range of the picking and receiving bins. By setting reasonable limit positions, it can be ensured that the picking and receiving bins do not exceed the predetermined safety range during rising or falling, thereby preventing equipment damage or workpiece falling due to overshoot. This precise positioning function is crucial for ensuring the stability and reliability of the feeding process; the presence of the limit cylinders also protects other related equipment from impacts and vibrations caused by excessive movement of the picking or receiving bins. This helps extend the service life of the equipment, reduce the frequency of maintenance and parts replacement, and thus reduce production costs.

[0028] The two cylinders, 512 (up and down cylinder for the picking bin) and 513 (up and down cylinder for the receiving bin), are the power sources for the lifting and lowering movements of the picking and receiving bins. By controlling the extension and retraction of these cylinders, the picking and receiving bins can be driven to rise or fall vertically, thereby achieving automatic picking and unloading of workpieces. This automated operation not only improves production efficiency but also reduces the labor intensity of workers.

[0029] like Figure 5 and Figure 6 As shown, the upper and lower limit cylinders 511 of the feeding bin are equipped with a material tray mechanism movable sleeve 518 on both sides. A material tray mechanism descent proximity sensor 517 is located on one side of the upper and lower limit cylinders 511 of the feeding bin, and a material tray mechanism ascending proximity sensor 515 is located on one side of the upper and lower limit cylinders 514 of the receiving bin. The movable sleeves 518 of the material tray mechanism provide a stable support structure for the vertical movement of the material tray within the feeding bin, ensuring that the material tray can move accurately along a predetermined path, reducing offset and swaying, and ensuring the stability and straightness of the material tray's vertical movement. The material tray mechanism descent proximity sensor 517 located on one side of the upper and lower limit cylinders 511 of the feeding bin can detect material movement in real time. The position of the tray mechanism during descent: When the tray descends to a preset limit position, the sensor immediately sends a signal to ensure that the tray will not collide with the bottom of the receiving hopper or other components due to excessive descent, thus protecting the equipment and the tray from damage. The tray mechanism rising proximity sensor 515, located on one side of the upper and lower limit cylinders 514 of the receiving hopper, functions similarly to the descending proximity sensor of the receiving hopper. The rising proximity sensor of the receiving hopper is used to detect the position of the tray mechanism in real time during the rising process. When the tray rises to a preset limit position, the sensor sends a signal to ensure that the tray will not collide with the top of the receiving hopper or other components due to excessive descent, thus ensuring the safety of the equipment and the tray.

[0030] like Figure 5As shown, a partition plate 6 is provided between the fixed component 2 and the tray gripping component 5. During equipment operation, the fixed component 2 and the tray gripping component 5 each have independent movement trajectories and ranges of motion. The partition plate 6 separates these two components, preventing collisions or interference during movement, ensuring that each component operates normally in a predetermined manner, and reducing equipment malfunctions and damage caused by component collisions. By setting the partition plate 6, the space where the fixed component 2 and the tray gripping component 5 are located can be divided into different functional areas, making the equipment structure clearer and easier for operators to understand and operate the equipment. At the same time, it also facilitates equipment maintenance and management, making it easier for maintenance personnel to quickly locate and repair faulty components.

[0031] Furthermore, all types of cylinders in this solution are commercially available parts.

[0032] Working principle: The tray gripping assembly 5, through the third cylinder 59 and the up-and-down moving cylinder, drives the tray gripping mechanism 52 to grip the tray containing the watch case from the tray area 71 of the interchangeable loading and unloading box; after gripping, the tray is moved to the designated position, where the first clamping mechanism 3 or the second clamping mechanism 4 removes the watch case; the removed watch case is placed in the fixing area 22 of the fixing assembly 2, where the movable clamping edge 24, driven by the first gripping finger cylinder 25, cooperates with the fixed bearing edge 23 to clamp the watch case, while the rotating pressing cylinder 26 drives the relevant structure to further fix the watch case, and the pressure block 21 and the base block 28 assist in positioning to ensure the stability of the watch case during processing; after the watch case has completed part of the processing in the fixing area 22, the flipping gripper 38 of the first clamping mechanism 3 moves to the watch case under the drive of the transverse slide 32 (driven by the first cylinder 33) and the longitudinal slide 35 (driven by the second cylinder 36), and grips the watch case. The first clamping swing cylinder 37 drives the flipping jaw 38 to flip the watch case so that the other side of the watch case can be processed; the first jaw 48 and the second jaw 46 of the second clamping mechanism 4 can work together to assist in transferring or adjusting the position of the watch case during processing. The second clamping swing cylinder 44 can drive the jaw to swing to adapt to different processing requirements. The air intake mechanism 41 and the contact separation device provide power support for the relevant pneumatic components. After the watch case is processed, it is taken out from the fixed area 22 by the second clamping mechanism 4 or the first clamping mechanism 3. The material tray gripping mechanism 52 moves the empty receiving tray from the receiving tray area 72 of the interchangeable loading and unloading box to the designated position. The finished watch case is placed in the receiving tray. Then the material tray gripping mechanism 52 sends the receiving tray full of finished products to the receiving tray area 72. The above loading, positioning, processing, flipping and unloading processes are repeated continuously to realize the cyclic operation of watch case processing. The isolation plate 6 serves to separate the fixing component 2 and the tray gripping component 5 to avoid mutual interference; each sensor (such as the tray left and right movement proximity sensor 57, etc.) is used to detect the position of the components to ensure precise coordination of each step.

[0033] In summary, this watch case internal rotating loading and unloading cyclic clamping processing fixture, through the cooperation of the material tray gripping component 5 and the interchangeable loading and unloading bins, can automatically complete the cyclic process of loading, processing, and collecting materials, reducing manual intervention; the material tray gripping mechanism 52 can automatically move and grip the material tray, and with the limit and sensing devices of the loading and unloading bins, it ensures accurate and efficient loading and unloading; the fixing component 2, through the fixed bearing edge 23, movable clamping edge 24, pressure block 21, base block 28 and other structures, combined with the first gripping finger cylinder 25 and the rotating pressing cylinder 26, can firmly fix the watch case and prevent displacement during processing; the rotating jaw 38 of the first clamping mechanism 3 can realize the rotation of the watch case, and the double jaw of the second clamping mechanism 4, in conjunction with the swing cylinder, can meet the processing requirements of different angles and improve processing flexibility; each mechanism is driven by slide rails and cylinders to ensure the accuracy of movement and clamping and reduce positioning errors; the material tray left and right movement proximity sensor 57, the material tray mechanism lifting proximity sensor and other devices can monitor the position in real time to ensure coordinated action.
