Description

Technical Field

[0001] This utility model relates to the field of bracket manufacturing technology, specifically to a bracket feeding device. Background Technology

[0002] In automotive component manufacturing, small brackets are critical components used to support, connect, or mount other parts. Small brackets typically consist of a robust frame, which may be rectangular, square, or other shapes suited to installation requirements. This frame provides the necessary structural strength and support for the entire bracket. The bottom of the bracket may be sleeve-shaped, meaning the base forms a cylindrical or similar hollow structure. This design allows the bracket to fit directly onto a column or other fixed point, providing a tighter and more stable connection.

[0003] Traditional loading devices typically use a single clamping cylinder to complete the loading and unloading process. While this design is simple and low-cost, it may lead to inefficiency and increased equipment load in certain situations. A single clamping cylinder can only handle one workpiece at a time. If the speed of the production line needs to be increased, the cycle time of the entire system is limited by the speed of this single action. Frequent start-stop operations will lead to accelerated wear of the pneumatic system and mechanical structure, increasing maintenance costs and downtime. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for a support, comprising a rotating table and a vertical frame installed on a feeding platform, wherein multiple workstation ends are installed on the table surface of the rotating table, and two sets of adjusting components are installed on the vertical frame, wherein a rotating plate is rotatably connected to the bottom of the adjusting components, and two sets of clamping cylinders are installed at the bottom of the rotating plate.

[0005] The adjustment assembly includes two sets of lifting ends mounted on the upright frame, and a lifting platform slidably connected to the corresponding lifting ends. A rotating assembly that drives the rotating plate to rotate is mounted on the lifting platform.

[0006] Furthermore, the lifting end is a downward-pushing cylinder installed on the top of the upright, and the piston rod of the downward-pushing cylinder is fixed to the lifting platform.

[0007] Furthermore, the lifting platform is L-shaped, and two reinforcing plates are fixed on the lifting platform.

[0008] Furthermore, the rotating assembly includes a rotating rod rotatably connected to the lifting platform, and a drive unit installed to drive the rotating rod to rotate, wherein the top of the rotating plate is fixed to the bottom of the corresponding rotating rod.

[0009] Furthermore, the drive unit includes a side-push cylinder mounted on the lifting platform and a rack slidably connected thereto. The piston rod of the side-push cylinder is fixed to the rack, and a gear that meshes with the rack is fixed to the outer side of the rotating rod.

[0010] Furthermore, a positioning block is fixed on the outer side of the rotating rod above the gear, and connecting rods are fixed on the top of the positioning block and the side wall of the lifting platform. A tension spring is installed between the two connecting rods.

[0011] Furthermore, the workstation end includes a support plate fixed on the rotating table surface, a protruding column fixed on one side of the support plate, and a rotating shaft rotatably connected to both sides of the protruding column. A clamping block is fixed on the outside of the rotating shaft, and a tension spring is installed between the clamping block and the protruding column.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The feeding device of this bracket can move the lifting platform up and down by adjusting the lifting end of the component. At the same time, the rotating plate moves accordingly. One set of clamping cylinders at the bottom of the two rotating plates clamps and fixes the external bracket, while the other set clamps the bracket at the workstation end. Then, by rotating the component, the position of the two clamping cylinders at the bottom of each set can be adjusted by the rotating plate. The corresponding bracket is then loaded and unloaded by moving the lifting end down. At the same time, it can also complete the preparation work for the loading and unloading operation of the next set. Therefore, it can effectively improve the feeding efficiency and reduce the load on the device. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-3 The feeding device for a bracket in this embodiment includes a rotating table 1 and a vertical frame 3 installed on the feeding platform. Four sets of workstation ends 2 are installed on the table surface of the rotating table 1. Two sets of adjustment components are installed on the vertical frame 3. A rotating plate 7 is fixed to the rotating end of the adjustment component. A pair of clamping cylinders 8 are fixed to the bottom of the rotating plate 7.

[0020] In the above structure, the left adjustment component drives the rotating plate to move down, and the left clamping cylinder clamps and fixes the bracket at the loading point, moving it to the upper part of the corresponding workstation. At this time, the right clamping cylinder returns to the loading point. When the left clamping cylinder completes the placement of the bracket, the other clamping cylinder clamps the bracket again to complete the loading operation. At the same time, the right adjustment component will also drive the two clamping cylinders to move the bracket off the workstation according to the same principle. Therefore, the loading and unloading speed can be effectively improved, thereby improving the processing efficiency and reducing the load on the device. The rotating table can drive the workstation to move below the designated process to complete the processing operation.

[0021] The adjustment assembly consists of a lifting end and a rotating assembly 5. The lifting end includes two downward-pushing cylinders 4 fixed to the top of the upright 3 and an L-shaped lifting platform 6 slidably connected to the front. The piston rods of the downward-pushing cylinders 4 are fixedly connected to the corresponding lifting platforms 6. The rotating assembly 5 is mounted on the lifting platform 6, and the rotating plate 7 is fixed to the rotating end of the rotating assembly 5. During the loading and unloading process, the downward-pushing cylinders push the corresponding lifting platforms downward. The lifting platforms, through the rotating assembly, drive the rotating plate to move downward, thus driving the corresponding two clamping cylinders to lift and lower. This, in conjunction with the corresponding clamping cylinders, completes the material loading and unloading operations. Furthermore, the rotating assembly drives the corresponding rotating plate to rotate, adjusting the position of the corresponding clamping cylinders. Combined with the downward-pushing cylinders, this completes the loading and unloading operations of the support frame.

[0022] Furthermore, two reinforcing plates are fixed between the platform surface and the side wall of the lifting platform 6. These reinforcing plates ensure the stability of the lifting platform.

[0023] Additionally, the rotating assembly includes a side-push cylinder 503 mounted on the lifting platform 6, a rack 504 slidably connected to it, and a rotating rod 505 rotatably connected to and fixed to the corresponding rotating plate 7. The piston rod of the side-push cylinder 503 is fixed to the corresponding rack 504, and a gear 506 meshing with the rack 504 is fixed to the outer side of the rotating rod 505. The operation of the side-push cylinder drives the rack to reciprocate, thereby enabling the rotating rod to rotate through the engagement of the rack and gear, thus rotating the rotating plate and adjusting the position of the clamping cylinder.

[0024] To further explain, a positioning block 507 is fixed to the outer side of the rotating rod 505, located above the gear 506. Connecting rods 508 are fixed to the top of the positioning block 507 and the side wall of the lifting platform 6. A tension spring 509 is fixed between the two connecting rods 508. When the rotating rod rotates, it rotates together with the positioning block. Simultaneously, the tension spring 509 stretches between the two connecting rods, providing a buffering effect. During reset, the tension reduces the load on the side-push cylinder. In the event of a sudden power outage, the rebound of the tension spring 509, in conjunction with the connecting rod on the positioning block, pulls the rotating rod to rotate. Therefore, the gear also drives the rack to reset, simultaneously restoring the two clamping cylinders to their original positions and completing the position correction.

[0025] like Figure 2 As shown in the diagram, the workstation end 2 includes a support plate 201 fixed on the rotating table 1. A protruding post 204 is fixed to the front of the support plate 201, and rotating shafts 202 are rotatably connected to both sides of the protruding post 204. Clamping blocks 203 are fixed to the outer side of the rotating shafts 202. One end of the clamping block 203 at the head end of the protruding post 204 forms a slope. Tension springs 205 are fixed between the opposite sides of the two clamping blocks 203 and the protruding post 204. When the clamping cylinder clamps the bracket onto the protruding post, during the downward movement, because the opposite ends of the clamping blocks form a slope, the two clamping blocks can be moved back to back by pressing down, while the tension springs 205 are stretched until the bracket is fitted onto the head end of the protruding post. Then, under the elastic force of the tension springs 205, the clamping blocks can be driven to clamp and fix the bracket, preventing it from shifting or being thrown out when the rotating table rotates to the bottom of the process, thus improving the stability of the bracket when the rotating table rotates.

[0026] The working principle of the above embodiments is as follows:

[0027] First, the rotating table continuously rotates, thereby adjusting the orientation of the workstation. The left-side push cylinder moves the lifting platform downward, and the left-side clamping cylinder clamps the external bracket. Simultaneously, the right-side clamping cylinder can fit the clamped bracket onto the protruding post. During the fitting process, the clamping block is squeezed, pushing the clamping block to open and close to a certain angle. At the same time, the tension spring is stretched. After the bracket is placed, the tension spring can drive the clamping block to clamp and fix the bracket, improving the stability during rotation. When the push cylinder resets, the side push cylinder drives the gear to rotate through the rack and pinion, which in turn drives the rotating rod to rotate. Therefore, the rotating plate follows the rotation, thereby driving the two sets of clamping cylinders to adjust their orientation, completing the lowering and picking operations again. At the same time, the right-side clamping cylinder works on the same principle as the loading principle to complete the unloading operation. In summary, this can improve the efficiency of loading and unloading, reduce the load on the equipment, and reduce the number of maintenance operations.
