Description

Technical Field

[0001] This utility model relates to a feeding mechanism, and more particularly to a sheet metal feeding mechanism for machine tool processing. Background Technology

[0002] In the process of machining sheet metal, the sheet metal is often manually moved onto the machine tool table for fixing. This method not only increases the workload of the workers, but also reduces the efficiency of sheet metal processing. Using a sheet metal feeding mechanism can reduce the workload of the operators.

[0003] For example, a feeding device for machine tool sheet metal processing, disclosed in Chinese Patent Publication No. CN218840937U, includes a base. Handles are fixedly connected to the right side of the base near the front and rear sides. This utility model, by setting up a feeding mechanism, through the cooperation of components such as a feeding servo motor, straight rod, sprocket, chain, movable block, movable frame, limit block, connecting rod, connecting plate, horizontal plate and push plate, enables the push plate to move to the left under the action of the first slide groove and the first slider, pushing the sheet metal body to move to the left under the action of several rollers. This eliminates the need for manual handling to the machine tool, reducing the workload of the workers. By setting up an adjustment mechanism, through the cooperation of components such as threaded rod, threaded tube, adjustment servo motor, worm, worm wheel and transmission belt, the load-bearing plate can move upward under the limit of several limit telescopic rods, making it suitable for machine tools of different heights and improving the application range of the device.

[0004] Some problems were found when using the existing feeding device for machine tool sheet processing. The device uses up-and-down adjustment and then pushes the sheet onto the machine tool processing table. Although it can reduce the use of manpower, it can only complete the feeding operation of one sheet at a time. After that, it is necessary to manually transfer the sheet back to the device, resulting in low feeding efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a sheet metal feeding mechanism for machine tool processing, so as to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal feeding mechanism for machine tool processing, comprising a movable base and a sheet metal to be processed, wherein the sheet metal to be processed is stacked on the movable base, a feeding frame is provided above the movable base, two sets of limiting uprights are symmetrically fixed to both sides of the movable base via support legs, a support beam is fixed to one of the limiting uprights, a height adjustment motor is fixed to the support beam, a high-strength lead screw is fixed to the output end of the height adjustment motor, two sets of limiting connecting ears are symmetrically fixed to both sides of the feeding frame, the limiting connecting ears are slidably engaged with clearance grooves, an internal threaded sleeve is fixed to one side of the feeding frame, the internal threaded sleeve is threadedly engaged with the high-strength lead screw, and a push frame is slidably connected above the feeding frame.

[0007] Preferably, omnidirectional wheels are fixedly installed on the bottom of the movable base near the four corner edges, a displacement handle is fixedly connected to the rear of the movable base, and a clearance groove is provided on the top of the movable base.

[0008] Preferably, the feeding rack includes two vertical plates and two horizontal plates. The two ends of the two horizontal plates are respectively fixed to the vertical plates. An installation groove is provided in the horizontal plate, and a roller is rotatably installed in the installation groove.

[0009] Preferably, a limiting groove is provided in the vertical plate, and limiting sliders are symmetrically fixed to the bottom of the push frame, with the limiting sliders slidingly engaging with the limiting groove.

[0010] Preferably, a threaded rod is rotatably installed in the limiting slide groove on one side, and a push motor is fixedly connected to the rear of the limiting slide groove on the other side, with the output end of the push motor fixedly connected to the threaded rod.

[0011] Preferably, a threaded through hole is provided in one side of the limiting slider, and the threaded through hole is threadedly engaged with the threaded rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By cooperating with the feeding rack and the pushing rack, the top layer of the stacked material plates to be processed can be transported to the machine tool processing table. Compared with the existing device, the stacked material plates to be processed can be transported to the machine tool one by one without having to move the material plates back and forth, thus improving the feeding efficiency.

[0014] 2. After pushing the material plate to be processed onto the feeding rack, start the height adjustment motor again to move the feeding rack upward. Moving the feeding rack upward can move the material plate to be processed to the same height as the machine tool processing table. Then, the material plate to be processed can be pushed onto the machining table, so that the device can adapt to machining and feeding operations at different heights. Attached Figure Description

[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] Please see Figure 1-4 This utility model provides a technical solution: a plate feeding mechanism for machine tool processing, including a movable base 1 and a plate to be processed 9. The plate to be processed 9 is stacked on the movable base 1. A feeding frame 3 is provided above the movable base 1. Two sets of limiting rods 104 are symmetrically fixed to both sides of the movable base 1 through support legs. A support beam 105 is fixed to one of the limiting rods 104. A height adjustment motor 2 is fixed to the support beam 105. A high-strength lead screw 201 is fixed to the output end of the height adjustment motor 2. Two sets of limiting connecting ears 307 are symmetrically fixed to both sides of the feeding frame 3. The limiting connecting ears 307 are slidably engaged with the clearance groove 103. An internal threaded sleeve 308 is fixed to one side of the feeding frame 3. The internal threaded sleeve 308 is threadedly engaged with the high-strength lead screw 201. A push frame 4 is slidably connected above the feeding frame 3.

[0022] In this embodiment, multiple workpieces 9 are neatly stacked on the movable base 1, and the device is moved to one side of the machine tool. Then, the height adjustment motor 2 is activated to rotate the high-strength lead screw 201. The high-strength lead screw 201 engages with the internal threaded sleeve 308, and the rotation of the high-strength lead screw 201, through the internal threaded sleeve 308, moves the feeding frame 3, adjusting its height so that the top of the feeding frame 3 is slightly lower than the bottom of the top workpiece 9 and higher than the bottom of the second workpiece 9. The pusher frame 4 is slidably mounted on the feeding frame 3, with its front aligned with the workpiece 9. Moving the pusher frame 4 forward can push the top workpiece 9... The workpiece plate 9 moves forward, pushing the workpiece plate 9 to be processed onto the feeding rack 3. The lower workpiece plate 9 is held in place by the feeding rack 3 to prevent it from being displaced by the upper workpiece plate 9. After the upper workpiece plate 9 is moved above the feeding rack 3, the height adjustment motor 2 is started to move the feeding rack 3 upward, making the workpiece plate 9 level with the machine tool processing table. Then, the pusher 4 continues to move forward, pushing the workpiece plate 9 to the processing bed, thus realizing the feeding operation of the workpiece plate 9. The above operation is then repeated to transport the stacked workpiece plates 9 to the machine tool one by one without having to move the workpiece plates 9 back and forth, thus improving the feeding efficiency.

[0023] In order to achieve the purpose of lifting the material plate 9 to be processed, the device adopts the following technical solution: universal wheels 101 are fixedly installed at the four corners of the bottom of the movable base 1, displacement handles 102 are fixedly connected to the back of the movable base 1, and clearance grooves 103 are opened on the top of the movable base 1. The feeding rack 3 includes two vertical plates 301 and two horizontal plates 302. The two ends of the two horizontal plates 302 are fixedly connected to the vertical plates 301 respectively. The horizontal plates 302 have mounting grooves, and rollers 303 are rotatably installed in the mounting grooves.

[0024] The casters 101 allow the device to move freely on the ground, facilitating adjustments to its position or the movement of the workpiece 9. The displacement handle 102 allows operators to grip and push the device. The clearance groove 103 works in conjunction with the feeding rack 3. When feeding the bottom workpiece 9, the feeding rack 3 engages with the clearance groove 103, allowing the workpiece 9 to be smoothly pushed onto the feeding rack 3. The horizontal plate 302 is positioned horizontally in front of the movable base 1. After pushing the workpiece 9 onto the horizontal plate 302, it can be lifted to the same height as the machine tool. The rollers 303 are rotatably installed inside the horizontal plate 302, facilitating the movement of the workpiece 9 on the horizontal plate 302.

[0025] To achieve the purpose of controlling the movement of the push frame 4, the device adopts the following technical solution: a limiting groove 304 is opened in the vertical plate 301, and a limiting slider 401 is symmetrically fixed to the bottom of the push frame 4. The limiting slider 401 slides in cooperation with the limiting groove 304. A threaded rod 305 is rotatably installed in the limiting groove 304 on one side. A push motor 306 is fixedly connected to the back of the limiting groove 304 on one side. The output end of the push motor 306 is fixedly connected to the threaded rod 305. A threaded through hole 402 is opened in the limiting slider 401 on one side. The threaded through hole 402 is threaded in cooperation with the threaded rod 305.

[0026] By starting the push motor 306, the threaded rod 305 can be rotated. The threaded rod 305 is threadedly engaged with the threaded through hole 402. The rotation of the threaded rod 305 can drive the threaded through hole 402 to move. The movement of the limit slider 401 can drive the push frame 4 to move. The push frame 4 can be used to push the material plate 9 to be processed forward.

[0027] The working principle and usage process of this utility model are as follows: Multiple workpieces 9 are neatly stacked on the movable base 1. The device is moved to the side of the machine tool. Then, the height adjustment motor 2 is started to drive the feeding frame 3 to move, so that the top of the feeding frame 3 is slightly lower than the bottom of the top workpiece 9 and higher than the bottom of the second workpiece 9. The push motor 306 is started to drive the push frame 4 to move forward. The push frame 4 can push the workpiece 9 onto the horizontal plate 302, so that the two horizontal plates 302 are located at the center of the workpiece 9. At this time, the height adjustment motor 2 can be started again to drive the feeding frame 3 to move upward. The push frame 3 can move the workpiece 9 to the same height as the machine tool processing table. The push motor 306 is started again to drive the push frame 4 to move forward. At this time, the push frame 4 can push the workpiece 9 onto the machine tool processing table, completing the loading operation of the workpiece 9 without manual handling.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
