[0029] Example 1

[0030] Reference Figures 1 to 3 This is the first embodiment of the present invention, which provides a clamping device for processing metal bars, comprising:

[0031] The base 100 has baffles 101 fixedly connected to both sides of its upper surface, and electric guide rails 103 are provided inside the baffles 101.

[0032] The clamping mechanism 200 is used to clamp the workpiece. The clamping mechanism 200 includes a mounting plate 201 and an auxiliary clamping assembly 206. The mounting plate 201 is provided with multiple clamping rings 202 on opposite outer surfaces of the mounting plate 201. An electric push rod 203 is fixedly connected to the outer surface of the clamping ring 202. A clamping block 204 is fixedly connected to the output end of the electric push rod 203. The auxiliary clamping assembly 206 is provided on the outer surface of one of the mounting plates 201.

[0033] Specifically, the electric guide rail 103 is set in two sections, which can easily control the clamping mechanisms 200 on both sides to move closer or further apart, making it easy to adjust according to the length of the bar and to transport the processed bar out.

[0034] In use, the bar is placed inside the clamping mechanism 200 and then the electric push rod 203 is activated to push the clamping block 204 for clamping. Before clamping, the electric guide rail 103 is activated to adjust the distance between the two clamping mechanisms 200 to accommodate different bars. After processing, one side of the clamping mechanism 200 is opened, and then the side holding the bar is transported to one end of the machine using the electric guide rail 103. Then, the auxiliary clamping assembly 206 is activated to push the bar outward until the bar is fed into the next stage.

[0035] Example 2

[0036] Reference Figures 2 to 4 This is the second embodiment of the present invention. Unlike the previous embodiment, mounting screws 104 are provided at all four corners of the upper surface of the base 100. The baffles 101 are symmetrically arranged and are divided into two sections. One side of the outer surface of one baffle 101 has a groove 102, and the rear outer surface of the electric guide rail 103 is fixedly connected to the inside of the groove 102. The other side of the outer surface of one baffle 101 has a track. A horizontal plate is provided at the lower end of the mounting plate 201. One end of the horizontal plate of the mounting plate 201 is slidably connected to the outer surface of the electric guide rail 103, and the other end of the horizontal plate of the mounting plate 201 is slidably connected to the inside of the track. A support plate is provided on one side of the outer surface of the horizontal plate of the mounting plate 201 and is connected to the outer surface of the auxiliary clamping assembly 206.

[0037] Specifically, the cooperation between the track and the electric guide rail 103 can keep the mounting plate 201 stable during movement, and the base 100 can be installed at the processing position of the processing machine by mounting screws 104, which facilitates the setting of the device.

[0038] Furthermore, the outer surface of the mounting plate 201 has a through hole, the clamping ring 202 is installed on one side of the through hole, and the auxiliary clamping assembly 206 is set on the other side of the through hole. Multiple auxiliary rollers 205 are rotatably connected to opposite sides of the clamping block 204. The auxiliary rollers 205 are used to reduce the friction when the bar moves, and the clamping rings 202 on both sides are symmetrically arranged.

[0039] Specifically, the through hole can hold the bar material in place, and the electric push rod 203 can clamp a fixed or smaller type of bar material within the through hole range. The rotation direction of the auxiliary roller 205 is consistent with the running direction of the electric guide rail 103, which can keep the bar material moving in the horizontal direction.

[0040] Furthermore, the auxiliary clamping assembly 206 includes a placement cylinder 2061. One end of the placement cylinder 2061 is fixedly connected to the outer surface of the mounting plate 201 and flush with the through hole. A drive motor 2065 is fixedly connected to the upper surface of the placement cylinder 2061. A lead screw 2066 is fixedly connected to the output end of the drive motor 2065. An upper frame 2067 is threadedly connected to the outer surface of the lead screw 2066. A lower frame 2062 is fixedly connected to the inner bottom wall of the placement cylinder 2061. A miniature conveyor belt 2063 is provided inside both the upper frame 2067 and the lower frame 2062. An adsorption rubber block 2064 is fixedly connected to the outer surface of the miniature conveyor belt 2063. A groove is formed on the upper surface of the adsorption rubber block 2064. Multiple slide rods 2068 are slidably connected inside the upper frame 2067. The two ends of the slide rods 2068 are fixedly connected to the inside of the placement cylinder 2061. Both sides of the mounting plates 201 are provided with placement cylinders 2061 on opposite sides, and one of the placement cylinders 2061 has a tray inside for placing the rods.

[0041] Specifically, both sides are equipped with placement cylinders 2061, but their internal structures are different. This can reduce the occurrence of stagnation caused by different transmission forces on both sides. Moreover, the weight difference between the two sides is not significant, which can maintain balance and facilitate installation and handling. The grooves on the upper surface of the adsorption rubber block 2064 can form a suction cup effect to adsorb the rod and improve friction.

[0042] In use, first, install the device on the machining position of the processor using the mounting screws 104. Then, start the electric guide rail 103 to adjust the clamping mechanisms 200 on both sides to the appropriate position. Next, place the bar inside the clamping ring 202 and start the electric push rod 203 to push the clamping block 204 to clamp the bar. At the same time, the drive motor 2065 drives the lead screw 2066 to rotate, pushing the upper frame 2067 downward to make the adsorption rubber block 2064 clamp the bar. During processing, the machining position can be adjusted by the electric guide rail 103, or the micro conveyor belt 2063 can be started to use the adsorption rubber block. 2064 drives the rod to move. During the movement of the rod, the auxiliary roller 205 ensures smooth operation, while the clamping block 204 stably clamps the rod. After processing, the electric push rod 203 on one side retracts and opens, and then the electric guide rail 103 is activated to transport the side holding the rod to one end of the machine. Then, the micro conveyor belt 2063 is activated, and the adsorption rubber block 2064 drives the rod to move outward until the rod is sent into the next stage or falls into the storage box. Then, the above steps are repeated, which can reduce the disassembly and installation process and facilitate use.

[0043] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
