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] Example: Figures 1-5 As shown, this utility model provides a quenching furnace feeding device, including a trolley frame 1. Two symmetrically arranged cantilever arms 2 are fixedly installed on the upper end of the trolley frame 1. Several movable grippers 3 are slidably connected to each cantilever arm 2. Each movable gripper 3 includes a gripper base 31. Upper pulleys 32 are rotatably connected to the lower surfaces of the front and rear ends of the gripper base 31. A central shaft 33 is rotatably connected to the front and rear ends of the middle part of the gripper base 31. Connecting rods 34 are rotatably connected to the left and right ends of the central shaft 33. A gripper arm 35 is rotatably connected to the end of the connecting rod 34 away from the central shaft 33. The lower end of the gripper arm 35 is slidably connected to the upper surface of the gripper base 31. Symmetrical support legs 4 are fixedly installed on the lower end of the trolley frame 1.

[0020] By adopting the above technical solution, the trolley frame 1 serves as the basic support structure of the entire device, providing a stable connection base for the upper cantilever 2 and the lower support leg 4. The two cantilever 2 at its upper end are symmetrically arranged. This symmetrical structure can ensure the balance and stability of the device during the feeding process. Several movable grippers 3 slidably connected on the cantilever 2 can be flexibly adjusted to adapt to workpieces of different sizes and shapes.

[0021] A heat-resistant plate 311 is fixedly installed on the upper surface of the gripper base 31, and a clamping arm 36 is provided on both sides of the gripper base 31. A lower pulley 37 is rotatably connected to the lower end of both sides of the clamping arm 36, and a threaded wrench 38 is threadedly connected to the side wall of the clamping arm 36.

[0022] By adopting the above technical scheme, the heat-resistant plate 311 fixedly installed on the upper surface of the clamping jaw base 31 can effectively resist the high-temperature environment near the quenching furnace, prevent the clamping jaw base 31 from being deformed or damaged due to high temperature, and ensure the normal work of the whole movable clamping jaw 3. The holding arms 36 arranged on both sides of the clamping jaw base 31 play the role of auxiliary support and stability, and enhance the overall structural strength of the clamping jaw base 31.

[0023] The middle shaft rod 33 is provided with a reset spring 331 around, the top end of the clamping arm 35 is fixedly installed with an elastic sheet 351, the middle part of the elastic sheet 351 is fixedly installed with a clamping spring 352, and the other end of the clamping spring 352 is fixedly connected to the surface of the clamping arm 35.

[0024] By adopting the above technical scheme, the reset spring 331 arranged around the middle shaft rod 33 can provide a reset force for the clamping arm 35 after the clamping arm 35 releases the workpiece, so that the clamping arm 35 quickly returns to the initial position for the next clamping operation.

[0025] The top end of the cantilever 2 is provided with two upper sliding rails 21, and the two sides of the cantilever 2 are provided with lower sliding rails 22.

[0026] The lower sliding wheel 37 is connected with the lower sliding rail 22 in a matched mode, and the upper sliding wheel 32 is connected with the upper sliding rail 21 in a matched mode.

[0027] By adopting the above technical scheme, the lower sliding wheel 37 is connected with the lower sliding rail 22 in a matched mode, and the upper sliding wheel 32 is connected with the upper sliding rail 21 in a matched mode. The double-sliding-rail structure design ensures that the movable clamping jaw 3 can slide smoothly and accurately on the cantilever 2.

[0028] The lower side of the cantilever 2 is fixedly provided with a tray sliding rail 23, the tray sliding rail 23 is slidably connected with a tray wheel 51, and the inner side of the tray wheel 51 is rotatably connected with a tray 5.

[0029] By adopting the above technical scheme, the tray sliding rail 23 fixedly arranged on the lower side of the cantilever 2 provides guidance and support for the movement of the tray 5.

[0030] The lower end of the trolley frame 1 is provided with a track 6, the front end of each supporting leg 4 is fixedly installed with a sweeper 41, the outer surface of the sweeper 41 is attached to the upper surface of the track 6, and the inside of the sweeper 41 is provided with a cleaning brush 411 matched with the track 6.

[0031] By adopting the above technical scheme, the sweeper 41 fixedly installed at the front end of the supporting leg 4 has its outer surface attached to the upper surface of the track 6, so that the large-particle impurities on the track 6 can be cleaned in real time during the movement of the device.

[0032] The inner side of the threaded wrench 38 is fixedly installed with a brake sheet 381, the brake sheet 381 is made of high-temperature-resistant ceramic, and one side in contact with the cantilever 2 is roughened.

[0033] By adopting the technical scheme, the brake piece 381 fixedly arranged on the inner side of the screw wrench 38 is made of high-temperature-resistant ceramic material, can adapt to the high-temperature environment near the quenching furnace, and ensures that the brake piece 381 can still maintain good performance under high-temperature conditions. The side of the brake piece 381 in contact with the cantilever 2 is roughened to increase the friction between the brake piece 381 and the cantilever 2. When the screw wrench 38 rotates, the friction between the brake piece 381 and the cantilever 2 changes, so that the clamping force of the movable clamping jaw 3 can be more accurately adjusted to meet the clamping requirements of different workpieces.

[0034] Working principle: When the utility model is used, the worker first places the workpiece to be quenched on the feeding device. For workpieces with regular shapes and suitable for clamping, the workpiece is fixed by operating the movable clamping jaw 3. The clamping arm 35 of the movable clamping jaw 3 can swing flexibly under the action of the connecting rod mechanism. The lower end of the clamping arm 35 slides on the upper surface of the clamping jaw base 31. At the same time, the upper pulley 32 on the clamping jaw base 31 and the lower pulley 37 on the arm 36 slide on the upper slide rail 21 and the lower slide rail 22 of the cantilever 2 respectively, so that the movable clamping jaw 3 can be accurately moved to the appropriate position and clamp the workpiece. The trolley frame 1 provides support for the entire device, and the support legs 4 at the lower end ensure that the device stands stably. The sweeper 41 at the front end of the support leg 4 sweeps the track 6 during the movement of the device. When the device moves along the track 6, the track 6 provides guidance for the trolley frame 1. For scattered workpieces that are not suitable for clamping, the worker can slide the tray 5 to the appropriate position at the front end. The tray 5 slides on the tray slide rail 23 on the lower side of the cantilever 2 through the tray wheel 51, and the scattered workpieces are placed on the tray 5 for feeding operation. During the feeding process, the worker pushes the trolley frame 1 to move along the track 6 towards the quenching furnace. When the quenching furnace inlet is reached, the workpiece is accurately fed into the quenching furnace for quenching treatment. Through the close cooperation between the various components, efficient and stable quenching furnace feeding operation is realized.

[0035] Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalent technologies, the utility model also intends to include these modifications and variations.
