[0032] 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.

[0033] Referring to Figures 3, 4, and 5, one embodiment of this utility model provides a multifunctional fixture for automated assembly lines, comprising a base 1 and multiple telescopic clamping blocks 4. The top of the base 1 has multiple positioning holes 3, serving as the basic support structure for the fixture. The positioning holes 3 on the top provide sliding connection positions for the positioning rods 5 at the bottom of the telescopic clamping blocks 4. Each telescopic clamping block 4 has two fixedly connected positioning rods 5 at its bottom, and these positioning rods 5 are slidably connected to their corresponding positioning holes 3. The telescopic clamping blocks 4 achieve initial positioning through the cooperation of the bottom positioning rods 5 with the positioning holes 3, for use in... The clamping components are secured by two pre-drilled slots 6 on the outer walls of multiple positioning rods 5. A locking block 7 is slidably connected to the inner wall of each slot 6. The locking block 7 slides within the slot 6 and engages with a fixing sleeve 9 to fix the positioning rod 5, thereby fixing the position of the telescopic clamping block 4. A spring 8 is fixedly connected to each adjacent side of the locking blocks 7, providing elastic restoring force so that the blocks 7 can pop out of the slot 6 when not subjected to external pressure. Each adjacent end of the spring 8 is fixedly connected to a positioning rod 5. A fixing sleeve 9 is slidably connected to the outer wall of each positioning rod 5. The fixing sleeve 9 slides on the positioning rod 5. In conjunction with the locking block 7, the positioning rod 5 is locked and unlocked, thereby fixing or releasing the telescopic clamp 4. The outer walls of the multiple fixing sleeves 9 are provided with a sliding groove (10) for cooperating with the locking block 7. When the locking block 7 is engaged in the sliding groove (10), the movement of the positioning rod 5 relative to the fixing sleeve 9 is restricted, thereby fixing the telescopic clamp 4. The inner walls of the multiple sliding grooves (10) are slidably connected with push rods 11. When the position of the telescopic clamp 4 needs to be adjusted, the push rods 11 are used to press the locking block 7 to disengage it from the sliding groove (10), thereby releasing the restriction on the positioning rod 5. The top front side of the base 1 is fixed. A fixed rod 12 is fixedly connected to the base 1, which is used to install the positioning device 13 and provide a stable installation position for the positioning device 13. The positioning device 13 is fixedly connected to the rear side of the outer wall of the fixed rod 12, which is used to scan the size of the parts and provide data support for controlling the extension length of the telescopic clamping block 4, so as to achieve precise clamping of parts of different sizes. Air pipes 14 are fixedly connected to the opposite sides of the multiple telescopic clamping blocks 4, which are used to connect to an external air source to provide power to the telescopic clamping blocks 4 so that they can realize telescopic movement. An adjustment mechanism 2 is provided at the bottom of the base 1, which is used to adjust the height of the base 1.

[0034] Specifically, the base 1 serves as the basic support structure of the fixture. Multiple positioning holes 3 are opened at the top to provide sliding connection positions for the positioning rods 5 at the bottom of the telescopic clamping blocks 4. This allows the spacing of the telescopic clamping blocks 4 to be adjusted according to the size of the parts. The telescopic clamping blocks 4 achieve initial positioning by cooperating with the positioning rods 5 and positioning holes 3 at the bottom, and are used to clamp the parts. The reserved groove 6 on the outer wall of the positioning rod 5 is slidably connected to the locking block 7. Under the action of the spring 8, the locking block 7 can move in the reserved groove 6. One end of the spring 8 is connected to the locking block 7, and the other end is fixed to the positioning rod 5, providing a reset elastic force for the locking block 7. The fixing sleeve 9 is slidably connected to the outer wall of the positioning rod 5. The sliding groove 1 (10) on its outer wall is slidably connected to the push rod 11. When the fixing sleeve 9 slides upward, it contacts the locking block 7 and squeezes it into the reserved groove 6. Align 0 with the card block 7, the card block 7 pops out and snaps into the slide groove 1 (10), and pushes out the push rod 11, thereby fixing the positioning rod 5, so that the telescopic clamp 4 is stable on the base 1. The fixing rod 12 is fixed on the front side of the top of the base 1 to provide an installation position for the positioning instrument 13. The positioning instrument 13 is installed on the rear side of the outer wall of the fixing rod 12 to scan the size of the part and assist in controlling the extension length of the telescopic clamp 4. The air pipe 14 is connected to the side away from the telescopic clamp 4 to connect the external pipe and provide power to the telescopic clamp 4. The adjustment mechanism 2 is set at the bottom of the base 1 and adjusts the height of the base 1 through its own structure so that the fixture can be adapted to assembly lines of different heights. All components are closely matched to achieve fast and stable clamping of parts of different sizes and adjustment of fixture height, meeting the diverse needs of automated assembly lines.

[0035] Referring to Figures 1, 2, and 6, the adjustment mechanism 2 includes multiple bolts 201, which are key components for connecting and adjusting the height, providing support and power transmission for the height adjustment of the base 1. The tops of the multiple bolts 201 are fixedly connected to the bottom of the base 1 around the perimeter. Hollow sleeves 202 are slidably connected to the bottom of the outer wall of the multiple bolts 201, providing a sliding track for the bolts 201, limiting their movement direction, and ensuring the stability of the height adjustment. The bottom ends of the multiple hollow sleeves 202 are fixedly connected to the same base 203, providing a stable support foundation for the entire adjustment mechanism 2, ensuring the stability of the structure during the adjustment process. The inner walls of the multiple hollow sleeves 202 are provided with sliding grooves 204 on the left and right sides. The bottom sides of the outer walls of the multiple bolts 201 are fixedly connected with sliders 205. The multiple sliders 205 are slidably connected to the corresponding sliding grooves 204, limiting the movement trajectory of the bolts 201. The tops of the multiple hollow sleeves 202 are rotatably connected with rotating sleeves 206, and the multiple rotating sleeves 206 are threadedly connected to the corresponding bolts 201.

[0036] Specifically, multiple bolts 201 are fixed at the top around the bottom of the base 1, providing support and participating in height adjustment. The bottom of the outer wall of bolt 201 is slidably connected to the hollow sleeve 202. The bottom end of the hollow sleeve 202 is connected to the same base 203, which stabilizes the entire adjustment structure. The sliding grooves (204) on the left and right sides of the inner wall of the hollow sleeve 202 are slidably connected to the sliders 205 fixed on the left and right sides of the bottom of the outer wall of bolt 201, restricting bolt 201 to move only up and down and preventing it from rotating. The top of the hollow sleeve 202 is rotatably connected to the rotating sleeve 206. The rotating sleeve 206 is threadedly connected to the bolt 201. When the rotating sleeve 206 is rotated, based on the principle of thread transmission, the rotation of the rotating sleeve 206 is converted into an axial force on the bolt 201. Due to the restriction of the slider 205 and the second slide groove (204), the bolt 201 can only move up and down under the action of axial force. Multiple bolts 201 move synchronously, thereby realizing the adjustment of the height of the base 1, so that the fixture can be adapted to automated assembly lines of different heights.

[0037] Referring to Figures 1, 2, and 3, positioning openings 15 are provided around the top of the base 203. Bolts 16 are threadedly connected to the inner walls of the multiple positioning openings 15. The threaded connection between the positioning openings 15 and the bolts 16 allows the base 203 to be securely installed in the designated position. Rubber rings 17 are fixedly connected to the top of the multiple fixing sleeves 9. The tops of the multiple rubber rings 17 are in contact with the bottom of the base 1, increasing friction and securing the connection between the fixing sleeves 9 and the base 1. Limiting grooves 18 are provided around the inner walls of the multiple positioning holes 3. Two limiting strips 19 are fixedly connected to the outer walls of the multiple positioning rods 5. The multiple limiting strips 19 are slidably connected to the corresponding limiting grooves 18. The limiting grooves 18 and the limiting strips 19 on the outer walls of the positioning rods 5 are slidably connected, restricting the movement direction of the positioning rods 5, making the installation of the telescopic clamp 4 more stable and ensuring the reliability of the fixture.

[0038] Specifically, the positioning holes 15 around the top of the base 203 are threadedly connected to the bolts 16, which can securely install the base 203 in the designated position. The rubber ring 17 on the top of the fixing sleeve 9 fits against the bottom of the base 1 to increase friction and secure the connection between the fixing sleeve 9 and the base 1. The limiting groove 18 on the inner wall of the positioning hole 3 is slidably connected to the limiting strip 19 on the outer wall of the positioning rod 5 to limit the movement direction of the positioning rod 5, making the installation of the telescopic clamp 4 more stable and ensuring the reliability of the fixture.

[0039] Referring to Figures 1, 2, and 7, a vertical pole 20 is fixedly connected to the top left side of the base 1 to support the lighting lamp 21. The lighting lamp 21 is fixedly connected to the top of the vertical pole 20 to illuminate the working area, making it convenient for operators to observe the assembly status of parts on the automated assembly line. Soft pads 22 are fixedly connected to adjacent sides of multiple telescopic clamping blocks 4 to prevent damage to the surface of parts when clamping them. Multiple anti-slip strips 23 are provided on adjacent sides of multiple soft pads 22 to increase the friction with the parts and make the clamping more stable. Washers 24 are fixedly connected to the inner walls of multiple positioning ports 15 to increase the friction between the bolts 16 and the positioning ports 15 and prevent the bolts 16 from loosening. The bottom ends of multiple bolts 16 all penetrate the washers 24.

[0040] Specifically, the upright 20 provides support for the lighting lamp 21, which is located at the top of the upright 20 and can illuminate the working area, making it convenient for operators to observe the assembly status of parts on the automated assembly line, thus improving the accuracy and efficiency of operation. The soft pad 22 can prevent the clamping block from damaging the surface of the parts when clamping them. The multiple anti-slip strips 23 on the soft pad 22 increase the friction with the parts, making the clamping more stable and preventing the parts from slipping during assembly. The gasket 24 fixed to the inner wall of the positioning port 15 can increase the friction between the bolt 16 and the positioning port 15, preventing the bolt 16 from loosening. The bottom end of the bolt 16 passes through the gasket 24, realizing a firm connection between the base 203 and other structures, ensuring the overall stability of the fixture.

[0041] Working principle: When positioning parts is required, firstly, based on the size of the parts, insert the two positioning rods 5 at the bottom of the multiple telescopic clamping blocks 4 into the appropriate positions in the multiple positioning holes 3 at the top of the base 1. This initial step lays the foundation for subsequent fixing and adjustment. Then, the fixing sleeve 9 is placed on the positioning rod 5 from the bottom of the reserved groove 6 and slides upward. During the sliding process, the fixing sleeve 9 contacts the locking block 7 and applies pressure to it, causing the locking block 7 to be squeezed and slide into the reserved groove 6, while simultaneously squeezing the spring 8. When the fixing sleeve 9 continues to move upward until the slide groove 10 is aligned with the locking block 7, since the locking block 7 is no longer under the pressure of the fixing sleeve 9, under the elastic force of the spring 8, the locking block 7 slides outward and locks into the slide groove 10. At this time, the locking block 7 pushes the push rod 11 outward from the slide groove 10. This series of actions allows the fixing sleeve 9 to restrict the positioning rod 5, thereby positioning the telescopic clamping blocks. 4. Securely fixed on base 1. Then, connect the pipe to the outside and air pipe 14. Then place the parts between multiple telescopic clamping blocks 4. At this time, the positioning instrument 13 scans the size of the parts and controls the corresponding telescopic clamping block 4 to extend to an appropriate length according to the scanning result, so as to achieve fast and stable clamping of the parts. When it is necessary to move the position of the telescopic clamping block 4, simply press the push rod 11 into the slide groove 10. The push rod 11 squeezes the card block 7, thereby releasing the restriction on the positioning rod 5. At this time, the fixing sleeve 9 can be quickly removed, so that the telescopic clamping block 4 can be readjusted to prepare for positioning and clamping the next part of different size. This greatly simplifies the operation steps when clamping parts of different sizes, avoids the tedious process of turning multiple screws to adjust the position of the clamp in the traditional way, saves a lot of time, and significantly improves the working efficiency of the automated assembly line.

[0042] Furthermore, the tops of multiple bolts 201 are fixedly connected to the bottom of the base 1 around the perimeter, providing support and height adjustment for the base 1. The bottom of its outer wall is slidably connected to the hollow sleeve 202. The bottom ends of multiple hollow sleeves 202 are connected to the same base 203. The base 203 plays the role of stabilizing and supporting the entire adjustment mechanism 2. When the height of the base 1 needs to be adjusted, the operator rotates the rotating sleeve 206. Due to the characteristics of the threaded connection, the rotation of the rotating sleeve 206 will be converted into an axial force on the bolts 201. Because of the sliding restriction between the slider 205 and the sliding groove 2 (204), the bolts 201 cannot rotate and can only move up and down under the action of this axial force. Multiple bolts 201 move up and down synchronously, thereby realizing the adjustment of the height of the base 1, so that the base 1 can adapt to assembly lines of different heights and meet the diverse production needs of automated assembly lines.
