Description

Technical Field

[0001] This application relates to the field of billboard bracket technology, and in particular to a billboard bracket card block assembly tooling. Background Technology

[0002] In the manufacturing and assembly of billboard brackets, the brackets are usually designed as detachable structures for easy transportation and storage. During transportation, the entire bracket assembly is disassembled into multiple parts to reduce space occupation and facilitate loading; after arriving at the destination, the multiple brackets are reassembled and put into use, thereby effectively improving the flexibility and convenience of billboard bracket installation.

[0003] The brackets are typically plug-in type, with the main body being a hollow aluminum alloy square tube. A plug-in block is inserted and fixed inside one end of the bracket, and the other end of the plug-in block is detachably plugged into another bracket. Because brackets are easily lost after disassembly, or finding a matching bracket during installation is troublesome, existing technology uses an elastic rope, with one end of the rope fixed to a locking block. One end of the elastic rope is fixed inside a bracket by the locking block, thus maintaining a flexible connection between the two matching brackets, facilitating quick connection during assembly.

[0004] In practical use, it has been found that the installation depth of the locking blocks affects the tension of the elastic cord. This not only affects the insertion and removal resistance of the two brackets but also the tension of the elastic cord when the bracket is disassembled, folded, and stored. Therefore, it is necessary to ensure the installation accuracy of the locking blocks to improve the user experience of the bracket product and extend the lifespan of the elastic cord. Utility Model Content

[0005] To ensure the installation accuracy of the card blocks, this application provides an assembly fixture for the card blocks of a billboard bracket, which has the effect of ensuring the installation accuracy of the card blocks and improving the installation efficiency of the card blocks.

[0006] The billboard bracket assembly tooling provided in this application adopts the following technical solution: An assembly fixture for a billboard bracket includes a base, a positioning plate at one end of the base, a length limiting block on one side of the positioning plate, the length limiting block being inserted into the bracket, and a locking block being engaged with the end of the length limiting block. The length limiting block contains an elastic rope for connecting the locking block. A slide table is slidably mounted on the base, and a clamping mechanism for clamping and fixing the bracket is mounted on the slide table. The axial direction of the bracket is parallel to the moving direction of the slide table. A driving mechanism for moving the bracket is mounted on the slide table. The clamping mechanism is located between the positioning plate and the driving mechanism, and the driving mechanism drives the bracket to move towards the positioning plate and abut against it.

[0007] By adopting the above technical solution, the bracket is first clamped and fixed on the slide by the clamping mechanism, and then the drive mechanism is started. The drive mechanism drives the bracket and the slide to slide synchronously. When one end of the bracket is inserted into the length limiting block and the end of the bracket is fully abutted against the positioning plate, the locking block at the end of the length limiting block away from the positioning plate is engaged in the bracket, completing the docking of the locking block and the bracket. The length limiting block can ensure the stretching length of the elastic rope and the depth of the locking block engaged in the bracket, thereby ensuring the installation accuracy of the locking block and improving the installation efficiency of the locking block.

[0008] Optionally, the clamping mechanism includes multiple clamping blocks, all of which are located on a slide. Each clamping block has a U-shaped clamping groove for inserting a bracket. The clamping block is also provided with a clamping mechanism that presses the bracket into the clamping groove.

[0009] By adopting the above technical solution, the bracket is embedded in the clamping groove, and the groove wall of the clamping groove provides radial limiting and fixation for the bracket. Then, the clamping mechanism presses the bracket from above to provide longitudinal limiting and fixation for the bracket. Through the cooperation of the clamping block and the clamping mechanism, the bracket can be fixed on the slide, so that the bracket and the slide can slide synchronously along the length of the base, preventing radial movement of the bracket and improving the insertion accuracy of the bracket and the clamping block.

[0010] Optionally, the clamping mechanism includes a fixed seat disposed on the clamping block, a connecting rod and a control rod rotatably disposed on the fixed seat, and a pressure rod disposed on the connecting rod. The control rod is perpendicular to the axis of the bracket, the pressure rod is perpendicular to the connecting rod, a limit rod is rotatably disposed on the control rod, the limit rod abuts against the connecting rod, and a pressure head is disposed at one end of the pressure rod near the clamping block, the pressure head abuts against the bracket.

[0011] By adopting the above technical solution, first rotate the pressure rod on the connecting rod so that the pressure head on the pressure rod abuts against the surface of the bracket. Then rotate the control rod, which drives the limit rod to abut against the connecting rod, thereby fixing the pressure rod to the connecting rod and forming a locking structure for the pressure rod, thus pressing the bracket tightly onto the clamping block. After the bracket is assembled, rotate the control rod in the opposite direction so that the limit rod separates from the connecting rod. The connecting rod drives the pressure head on the pressure rod away from the bracket, making it easier for the staff to remove the assembled bracket and effectively improving the efficiency of fixing the bracket on the slide.

[0012] Optionally, the pressure rod passes through the connecting rod, and two washers are sleeved on the pressure rod. The two washers are located on both sides of the connecting rod, and the washers abut against the side wall of the connecting rod. A locking element is provided on the side of the washer away from the connecting rod, and the locking element is threadedly connected to the pressure rod.

[0013] By adopting the above technical solution, the gasket is disengaged from the connecting rod side wall by loosening the locking component, then the extension length of the pressure rod and the pressure head is adjusted, and finally the locking component is tightened, so that the gasket is locked between the locking component and the connecting rod side wall, which is beneficial for adapting to brackets with different outer diameters.

[0014] Optionally, the positioning plate has a connecting groove, and the length limiting block has a receiving groove for accommodating the elastic rope. The receiving groove is opened along the length direction of the length limiting block, and the connecting groove is connected to the receiving groove.

[0015] By adopting the above technical solution, the elastic rope is embedded in the length limiting block, and the receiving groove forms a constraint on the elastic rope. The end of the elastic rope away from the locking block passes through the connecting groove and connects to the insert block, so that the elastic rope is kept in a horizontal tension state. At the same time, the limiting effect of the receiving groove can also ensure the stretching length of the elastic rope.

[0016] Optionally, the base is provided with multiple parallel guide rails, the length direction of which is parallel to the axis of the bracket, and the bottom of the slide table is provided with multiple sliders, which slide on the guide rails via the sliders.

[0017] By adopting the above technical solution, when the drive mechanism applies axial thrust to the bracket, the slide table below the bracket drives the slider to slide smoothly along the length direction of the guide rail, which facilitates the accurate insertion of the bracket into the outer wall of the length limiting block and helps to improve the assembly accuracy of the card block and the bracket.

[0018] Optionally, the driving mechanism includes a driving cylinder located on the side of the slide away from the positioning plate, the output shaft of the driving cylinder extending and retracting along the length of the base, and the output shaft of the driving cylinder abutting against the bracket.

[0019] By adopting the above technical solution, the extension force of the output shaft of the drive cylinder is converted into an axial thrust on the bracket, causing the bracket to slide on the guide rail until the bracket abuts against the positioning plate. Then the output shaft of the drive cylinder retracts and waits for the next start. There is no need to manually assemble the clip into the bracket, which effectively improves the assembly efficiency.

[0020] Optionally, the positioning plate is provided with an air circuit switch, which is used to control the start of the drive cylinder.

[0021] By adopting the above technical solution and installing the gas circuit switch in the area of ​​the positioning plate, the operator does not need to travel back and forth between the two ends of the base, making it convenient to observe the assembly status of the bracket and replace the next bracket within the area of ​​the positioning plate, thus making the operation convenient.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. First, the bracket is clamped and fixed on the slide table by the clamping mechanism. Then, the drive mechanism is started, which drives the bracket and the slide table to slide synchronously. When one end of the bracket is inserted into the length limiting block and the end of the bracket is fully abutting the positioning plate, the locking block at the end of the length limiting block away from the positioning plate is engaged in the bracket, completing the docking of the locking block and the bracket. The length limiting block can ensure the stretching length of the elastic rope and the depth of the locking block engaged in the bracket, thereby ensuring the installation accuracy of the locking block and improving the installation efficiency of the locking block. 2. The bracket is embedded in the clamping groove, and the groove wall provides radial limiting and fixation for the bracket. Then, the clamping mechanism presses the bracket from above to provide longitudinal limiting and fixation. Through the cooperation of the clamping block and the clamping mechanism, the bracket can be fixed on the slide, so that the bracket and the slide can slide synchronously along the length of the base, preventing radial movement of the bracket and improving the insertion accuracy of the bracket and the clamping block. 3. First, rotate the pressure rod on the connecting rod so that the pressure head on the pressure rod abuts against the surface of the bracket. Then, rotate the control rod, which drives the limit rod to abut against the connecting rod, thereby fixing the pressure rod onto the connecting rod and forming a locking structure for the pressure rod, thus pressing the bracket tightly onto the clamping block. After the bracket is assembled, rotate the control rod in the opposite direction to separate the limit rod from the connecting rod. The connecting rod then drives the pressure head on the pressure rod away from the bracket, making it easier for workers to remove the assembled bracket and effectively improving the efficiency of fixing the bracket on the slide table.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses an assembly tooling for billboard bracket blocks, referring to... Figure 1 and Figure 2 The system includes a base 1, which is elongated and has a positioning plate 2 fixedly connected to one end of the base 1 by bolts. The positioning plate 2 is L-shaped. A length limiting block 3 is welded and fixed to the side wall of the positioning plate 2. The length limiting block 3 is parallel to the length direction of the base 1. A locking block 23 is locked and fixed to the end of the length limiting block 3 away from the positioning plate 2. An elastic rope 5 is accommodated in the length limiting block 3, and one end of the elastic rope 5 is fixedly connected to the locking block 23. A slide table 6 is slidably provided in the middle of the base 1. The slide table 6 slides along the length direction of the base 1. A clamping mechanism 7 is provided on the slide table 6. The clamping mechanism 7 is used to clamp and fix the bracket 4. A driving mechanism 8 is provided at the end of the base 1 away from the positioning plate 2. The clamping mechanism 7 is located between the positioning plate 2 and the driving mechanism 8. The driving mechanism 8 drives the bracket 4 to move toward the positioning plate 2.

[0027] The drive mechanism 8 drives the bracket 4 to move, and the bracket 4 drives the clamping mechanism 7 and the slide table 6 to slide synchronously on the base 1, so that the length limiting block 3 is inserted into the end of the bracket 4 until the end of the bracket 4 abuts the positioning plate 2, thereby realizing the automatic docking of the bracket 4 and the card block 23. By determining the length of the length limiting block 3, it is easy to control the position of the card block 23 in the bracket 4, thereby ensuring the positional accuracy of the card block 23 installed in the bracket 4 and effectively improving the installation efficiency of the card block 23.

[0028] Reference Figure 1 and Figure 2 A connecting groove 14 is provided above the positioning plate 2, and the connecting groove 14 is opened in the direction of the positioning plate 2 away from the base 1; a receiving groove 15 for accommodating the elastic rope 5 is provided on the top of the length limiting block 3 along the length direction, and the receiving groove 15 is connected to the connecting groove 14; the insert block 24 is positioned by abutting against the side of the positioning plate 2 away from the length positioning block, one end of the elastic rope 5 is fixedly connected to the locking block 23, and the other end passes through the receiving groove 15 and the connecting groove 14 and is fixedly connected to the insert block 24, and the elastic rope 5 is always in a horizontal tension state.

[0029] The elastic rope 5 passes through the receiving groove 15 and the connecting groove 14, which can fix the insert block 24 and the locking block 23, and can also fix the locking block 23 to the end of the length limiting block 3 to achieve the pre-positioning of the locking block 23; the receiving groove 15 forms an axial constraint on the elastic rope 5, reducing the deviation of the elastic rope 5, so that the elastic rope 5 maintains a stable tension.

[0030] Reference Figure 1 and Figure 3The clamping mechanism 7 includes multiple clamping blocks 71. In this embodiment, two clamping blocks 71 are provided, and the two clamping blocks 71 are located at both ends of the slide table 6 respectively. The clamping blocks 71 are fixedly connected to the slide table 6 by bolts. A clamping groove 9 for accommodating the bracket 4 is provided above the clamping block 71. The clamping groove 9 is U-shaped, and the inner wall of the clamping groove 9 abuts against the outer wall of the bracket 4. After the bracket 4 is inserted into the clamping groove 9, the clamping block 71 clamps and fixes the bracket 4. The clamping block 71 is also provided with a pressing mechanism 10 that presses the bracket 4 into the clamping groove 9.

[0031] Reference Figure 1 , Figure 3 and Figure 4 The clamping mechanism 10 includes a fixed base 101, a connecting rod 102, a control rod 103, and a pressure rod 104. The fixed base 101 is fixedly connected to the upper part of the clamping block 71 by bolts. The connecting rod 102 is hinged to the upper part of the fixed base 101, and the control rod 103 is hinged to the lower part of the fixed base 101. The connecting rod 102 passes through the control rod 103. A limit rod 25 is hinged inside the control rod 103, and the connecting rod 102 also passes through the limit rod 25. An arc-shaped notch 19 is opened at the upper end of the fixed base 101, and the lower end of the limit rod 25 abuts against the inner wall of the arc-shaped notch 19. A stop block 20 is integrally formed on the limit rod 25, and the stop block 20 is located above the connecting rod 102. A pressure rod 104 is fixedly connected to the end of the connecting rod 102 away from the fixed base 101. A pressure head 11 is fixed to the end of the pressure rod 104 near the clamping block 71, and the pressure head 11 abuts against the upper surface of the bracket 4.

[0032] First, rotate the connecting rod 102 until the pressure head 11 on the pressure rod 104 abuts against the top of the bracket 4. Then, rotate the control rod 103. The control rod 103 drives the limiting rod 25 to rotate synchronously. The end of the limiting rod 25 rotates and abuts against the inner wall of the arc-shaped notch 19. When the stop block 20 on the limiting rod 25 rotates to abut against the connecting rod 102, and with the clamping action of the clamping block 71, the bracket 4 is fixed in the clamping groove 9. This facilitates the limiting of the bracket 4 from the axial and longitudinal directions, effectively improving the stability of the bracket 4 fixed in the clamping block 71.

[0033] Reference Figure 3 Two washers 12 are fitted on the pressure rod 104. The washers 12 are bent into a U-shape and are located on both sides of the connecting rod 102 and abut against the side wall of the connecting rod 102. Locking members 13 are threaded to both ends of the pressure rod 104. The locking members 13 are located on the side of the washers 12 away from the connecting rod 102. The pressure rod 104 passes through the end of the connecting rod 102 away from the fixed seat 101. By tightening the locking members 13, the two washers 12 can form a clamping force on the connecting rod 102, thereby fixing the pressure rod 104 on the connecting rod 102. At the same time, the extension length of the pressure head 11 can be adjusted to adapt to the bracket 4 with different outer diameters.

[0034] Reference Figure 1 Multiple guide rails 16 are fixedly connected to the base 1 by bolts. In this embodiment, two guide rails 16 are provided. The guide rails 16 are arranged along the length of the base 1 and are located between the positioning plate 2 and the drive mechanism 8. Multiple sliders 17 are fixedly connected to the bottom of the slide table 6 by bolts. The sliders 17 slide on the guide rails 16. When the bracket 4 is clamped and fixed to the clamping block 71, the drive mechanism 8 drives the bracket 4 to move. The bracket 4 drives the slide table 6 to slide on the guide rails 16 through the sliders 17. This helps to limit the lateral displacement of the slide table 6 during the movement and improves the stability of the docking between the bracket 4 and the clamping block 23.

[0035] Reference Figure 1 A support plate 21 is bolted to one end of the base 1 away from the positioning plate 2. The drive structure includes a drive cylinder 81, both ends of which are bolted to the support plate 21. The output shaft of the drive cylinder 81 extends and retracts along the length of the base 1. A movable plate 22 is bolted to the output shaft of the drive cylinder 81. The movable plate 22 is disc-shaped, and the side of the movable plate 22 away from the drive cylinder 81 abuts against the end of the bracket 4. An air circuit switch 18 is bolted to the side wall of the positioning plate 2. The start and stop of the drive cylinder 81 can be controlled by the air circuit switch 18.

[0036] When the air circuit switch 18 is activated, the output shaft of the drive cylinder 81 drives the bracket 4 to move toward the positioning plate 2 via the moving plate 22 until the bracket 4 is inserted into the length limit plate and abuts against the positioning plate 2, so that the locking block 23 is locked in the bracket 4. There is no need to move the bracket 4 manually, which effectively improves the assembly efficiency of the locking block 23 and the bracket 4.

[0037] The implementation principle of the billboard bracket clamp assembly tool disclosed in this application is as follows: The pneumatic switch 18 is activated, driving the cylinder 81 to move the bracket 4. The slide 6 slides synchronously along the guide rail 16 with the bracket 4. The length limiting block 3 is gradually inserted into the end of the bracket 4 until the end of the bracket 4 abuts against the positioning plate 2. At this time, the clamp 23 is clamped into the preset position inside the bracket 4 under the guidance of the length limiting block 3, completing the automatic docking. The length limiting block 3 determines the installation position of the clamp 23 and the stretching length of the elastic rope 5, thereby effectively ensuring the installation accuracy of the clamp 23 and improving the installation efficiency of the clamp 23.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
