[0027] In the related art, operators use a variety of pallets to accommodate workpieces of different sizes. The multiple pallets not only increase the demand for production space, but also increase the operating burden of operators, resulting in low production efficiency.
[0028] In order to solve the technical problem, the utility model proposes a workpiece limiting tool, a conveying tray and a production line.
[0029] See also Figure 1 In one embodiment of the utility model, the workpiece limiting tooling includes a base plate 100 and a plurality of limiting components 200, a limiting area is formed on the base plate 100; a plurality of limiting components 200 are arranged at intervals; the limiting components 200 include a mounting portion and a telescopic portion, the mounting portion is mounted in the limiting area, the telescopic portion is vertically telescopically mounted on the mounting portion, and the telescopic portion can be telescoped between an initial position away from the mounting portion and a compressed position that receives the workpiece and is pressed by the workpiece to be close to the mounting portion; at least one limiting component 200 is arranged against the periphery of the workpiece. Specifically, when the workpiece is not placed on the base plate 100, the telescopic part is often in a telescopic state away from the mounting part, that is, in the initial position. When the workpiece needs to be placed on the base plate 100, the workpiece first contacts the telescopic part, and the workpiece presses the telescopic part under the action of gravity, so that the telescopic part is compressed from the initial position toward the mounting part to the compressed position. Since at least one of the multiple limit assemblies 200 is against the periphery of the workpiece, after the workpiece presses some of the multiple limit assemblies 200 from the initial position to the compressed position, at least one limit assembly 200 located at the periphery of the workpiece is still in the initial position, so as to limit the workpiece within the limiting area of the base plate 100, thereby ensuring the stability of the workpiece when placed on the base plate 100. Since the telescopic parts in each limit assembly 200 can be telescoped vertically between the initial position and the compressed position, it can adapt to the limiting requirements of workpieces of various sizes.
[0030] More specifically, the limiting area of the base plate 100 provides a basic operating space for positioning and placing the workpiece; each limiting assembly 200 includes at least one mounting portion and at least one telescopic portion, the mounting portion is fixed to the limiting area of the base plate 100, and the telescopic portion is telescopically mounted on the mounting portion in a vertical direction. When the workpiece is placed on the limiting assembly 200, the telescopic portion can automatically and adaptively adjust from an initial position (away from the mounting portion) to a compressed position (close to the mounting portion), so that the workpiece limiting tooling can automatically adjust the limiting position according to the size and shape of the workpiece. When placing the workpiece, the workpiece first contacts the telescopic portion, and under the action of gravity, the workpiece presses the telescopic portion to the compressed position, reducing the need for manual adjustment and achieving the same pallet being able to automatically adapt to the use requirements of workpieces of various sizes and shapes.
[0031] As an optional implementation of the present embodiment, the base plate 100 has a thickness, and a plurality of mounting holes are formed on the base plate 100 along the thickness direction thereof. The number of the mounting holes is consistent with the number of the limiting components 200 and are arranged one-to-one. The mounting portion of the limiting component 200 is installed at the bottom of the base plate 100, and the telescopic portion of the limiting component 200 extends into the mounting hole and is exposed from the top of the mounting hole to the top of the base plate 100.
[0032] In the technical solution provided by the utility model, a plurality of limit assemblies 200 are arranged at intervals on the bottom plate 100, and a telescopic part of the limit assemblies 200 that is vertically telescopically installed on the mounting part is used to carry the workpiece. When the workpiece is placed, the workpiece first contacts the telescopic part, and under the action of gravity, the workpiece presses the telescopic part to a compressed position, thereby reducing the need for manual adjustment and achieving the automatic adaptation of the same pallet to meet the use requirements of workpieces of various sizes and shapes. This not only reduces the space requirements of the production site, but also reduces manual intervention, reduces the operating burden of operators, and significantly improves production efficiency. The workpiece limit fixture is adaptable and versatile, and there is no need to modify existing equipment. The workpiece limit fixture only needs to be assembled on the existing production line, thereby saving production costs.
[0033] There are many ways to implement the structure of the limit assembly 200. Figure 2In an embodiment of the utility model, the limit assembly 200 includes a limit plate 210, a guide column 220, an elastic member 230 and a mounting seat 240, the mounting seat 240 forms a mounting portion, and the limit plate 210 forms a telescopic portion; the guide column 220 extends vertically and is mounted on the mounting seat 240, the limit plate 210 is vertically slidably connected to the mounting seat 240 through the guide column 220, the elastic member 230 is sleeved on the guide column 220, and the elastic member 230 is arranged between the limit plate 210 and the mounting seat 240. The limit plate 210 is slidably connected to the mounting seat 240 along the vertical direction through the guide column 220, and the elastic member 230 is sleeved on the guide column 220, so that the limit plate 210 can move flexibly under different pressures, for example: when the limit plate 210 is pressed by the workpiece, the limit plate 210 moves downward in the direction close to the mounting seat 240 and compresses the elastic member 230, or, when the workpiece is removed from the limit plate 210, the elastic member 230 is reset under the elastic action to drive the limit plate 210 to move upward in the direction away from the mounting seat 240 to the initial position, thereby ensuring that workpieces of various sizes can be limited and fixed in the limiting area of the base plate 100; the elastic member 230 (such as a spring) increases the adaptability of the workpiece limiting tooling, and the telescopic portion, i.e., the limit plate 210, can automatically return to its initial position from the compressed position when not subjected to the pressure of the workpiece, providing space for placing new workpieces, allowing fast and continuous workpiece replacement, and further improving production efficiency.
[0034] Specifically, in the embodiment of the utility model, the limit plate 210 is formed with a vertical through hole 211, one end of the guide column 220 is inserted into the vertical through hole 211, and the other end of the guide column 220 is vertically slidably connected to the mounting seat 240. Through the cooperation of the vertical through hole 211 and the guide column 220, the limit plate 210 can achieve stable vertical movement on the mounting seat 240, ensuring the limiting stability of the workpiece when placed on the workpiece limiting fixture, and can also improve the positioning accuracy of the workpiece on the production line using the workpiece limiting fixture. In addition, the simple and effective assembly structure formed by the vertical through hole 211 and the guide column 220 reduces the friction and wear between the various components of the workpiece limiting fixture, improves the service life and reliability of the workpiece limiting fixture, and at the same time, it is convenient for the maintenance and maintenance of the workpiece limiting fixture, reducing the later operating costs. By connecting the limit plate 210 and the mounting seat 240 through the guide column 220, the stability and safety of the workpiece during transportation and handling are ensured, the misalignment or falling of the workpiece is effectively prevented, and the risk of accidents and losses on the production line are reduced.
[0035] As an optional implementation of this embodiment, when the limit plate 210 is in the compression position, the length of the guide column 220 extending into the vertical through hole 211 is less than the axial length of the vertical through hole 211, that is, the height of the vertical through hole 211. In other words, when the limit plate 210 is in the compression position, the length of the guide column 220 extending into the vertical through hole 211 is less than the thickness of the limit plate 210.
[0036] More specifically, in an embodiment of the utility model, the mounting seat 240 includes a mounting plate 241 and a sleeve 242, the sleeve 242 extends vertically and passes through the mounting plate 241, the mounting plate 241 is installed in the limiting area, the sleeve 242 is sleeved on one end of the guide column 220 away from the limiting plate 210, and the elastic member 230 is arranged between the sleeve 242 and the limiting plate 210. The sleeve 242 extends vertically and is inserted into the mounting plate 241, and the guide column 220 is slidably connected to the sleeve 242 vertically, so that the limit plate 210 can move up and down smoothly along the guide column 220, so that when the telescopic part is subjected to the pressure of the workpiece, it can stably and smoothly slide to the compression position, and the guide column 220 guides the limit plate 210, reducing the mechanical resistance and wear of the limit plate 210 during movement, and extending the service life of the workpiece limit fixture; the combination of the sleeve 242 and the guide column 220 not only provides a stable implementation basis for the movement of the limit plate 210, but also ensures the stability of the workpiece when the limit plate 210 is in the compression position, and ensures that the workpiece can also remain stable during transportation or handling, thereby reducing the risk of damage or dislocation of the workpiece. In addition, the simplified structural design (the combination of the sleeve 242 and the guide column 220) is easy to assemble and maintain, reducing the maintenance difficulties caused by the complex structure, and at the same time improving the overall reliability and durability of the workpiece limit fixture.
[0037] In the embodiment of the utility model, there are multiple mounting seats 240, and multiple mounting seats 240 are arranged at intervals; there are multiple guide posts 220, and the number of guide posts 220 is consistent with the number of mounting seats 240 and is arranged one-to-one; there are multiple elastic members 230, and the number of multiple elastic members 230 is consistent with the number of guide posts 220 and is arranged one-to-one; there are multiple vertical through holes 211, and the number of vertical through holes 211 is consistent with the number of guide posts 220 and is arranged one-to-one. The arrangement of multiple mounting seats 240, guide posts 220 and elastic members 230 ensures that the workpiece can be evenly supported and fixed on the bottom plate 100. Through evenly distributed support points, the workpiece can be stably placed in the limit area, avoiding instability or damage of the workpiece due to uneven support. Since the number of mounting seats 240, guide posts 220 and elastic members 230 is consistent and arranged one by one, the workpiece limiting fixture can bear the weight and pressure of the workpiece more evenly, improve the stability and reliability of the workpiece limiting fixture, and ensure that the transfer of the workpiece can continue to operate stably during the production process. In addition, the arrangement of multiple mounting seats 240, multiple guide posts 220 and multiple elastic members 230 enables the workpiece limiting fixture to adapt to workpieces of different sizes and shapes, enhances the adaptability and flexibility of the workpiece limiting fixture, enables it to cope with a variety of production needs, and improves the efficiency and diversity of the production line. Moreover, even if one of the limiting components 200 fails, the other limiting components 200 can still continue to work normally, reducing the impact of single-point failures on the entire production line and improving the reliability and stability of the production line.
[0038] In the embodiment of the utility model, in order to adapt to the thickness or contour of the workpiece, a vertical slot with a notch 110 facing upward is formed on the bottom plate 100 at a position corresponding to the limiting area, and a plurality of limiting components 200 are arranged at intervals along the periphery of the notch 110. The notch 110 is used to make way for the protruding part of the workpiece.
[0039] Specifically, the plurality of stopper assemblies 200 extend horizontally and along the length direction of the slot 110, so that each stopper assemblies 200 can contact the workpiece more comprehensively, ensuring that the workpiece can maintain a stable position during the entire assembly process, which helps to improve the quality and efficiency of the workpiece assembly process.
[0040] In the embodiment of the utility model, the bottom plate 100 is formed with a flange 120 along its periphery, the flange 120 extends vertically, and the flange 120 forms a limiting area. The flange 120 not only increases the rigidity of the bottom plate 100, but also forms a natural boundary through its vertical extension, which provides additional support and protection for the workpiece placed on the bottom plate 100, ensures the stability of the workpiece during transportation and handling, and reduces the risk of damage to the workpiece due to vibration or impact.
