Description

Technical Field

[0001] The utility model relates to a rod loading manipulator for an extrusion heating furnace. Background Art

[0002] The production process of aluminum alloy profiles involves an important process of heating, softening and extruding metal bars. In this process, the aluminum bars must first be heated and softened before they can be used in the extrusion process. After the aluminum bars are heated, the discharge will have a temperature difference with the heating furnace, cooling the aluminum bars and affecting the quality of the extrusion. Therefore, after the aluminum bars are heated and softened, they must be quickly put into the extrusion machine. The discharge track of the currently used chain-type aluminum ingot heating furnace cannot be directly connected to the feed track of the extrusion equipment, so the two processes usually require manual labor to realize the transmission of aluminum ingots, or use some simple concave roller structures for transmission. These measures are not only labor-intensive, but also prone to production safety accidents. Summary of the invention

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a rod loading manipulator for an extrusion heating furnace.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A rod loading manipulator for an extrusion heating furnace comprises a main frame, a spring adjustment mechanism installed above the main frame, and a clamping mechanism installed below the main frame for clamping and fixing metal rods. A main frame slide rail pair is fixedly installed at a position below the main frame corresponding to the clamping mechanism by screws.

[0006] Furthermore, the spring adjustment mechanism includes a spring adjustment guide rail pair fixedly mounted on the main frame by screws, a limit support seat located at both ends of the spring adjustment guide rail pair and fixedly mounted on the main frame by screws, a fixed rod fixedly mounted on the limit support seat, a connecting seat sleeved on the fixed rod and capable of sliding along the fixed rod, and an adjustment spring sleeved on the fixed rod and located on both sides of the connecting seat;

[0007] Furthermore, the clamping mechanism includes a trapezoidal mounting frame welded and fixed on both sides of the main frame, a driving motor installed on the side of one of the trapezoidal mounting frames, a transmission screw mounted on the trapezoidal mounting frame and connected to the driving motor, a support box installed in the center below the main frame for protecting the transmission screw, and a first chuck and a second chuck located on both sides of the support box and mounted on the transmission screw.

[0008] Preferably, a connecting seat slider is fixed to the lower end of the connecting seat by screws, and the connecting seat slider is movably assembled with the spring adjustment guide slide rail pair, so that the connecting seat can be easily adjusted by sliding left and right under the adjustment of the adjustment spring.

[0009] Preferably, the drive motor is fixed with a motor fixing seat by screws, a drive gear mounted on the output end of the drive motor, and a driven gear meshing with the drive gear and mounted on the transmission screw.

[0010] Preferably, the transmission screw comprises a forward threaded rod body and a reverse threaded rod body connected to the forward threaded rod body.

[0011] Furthermore, a forward threaded rod joint is welded at a portion where the forward threaded rod body is connected to the reverse threaded rod body, and a reverse threaded rod joint is welded at a portion where the reverse threaded rod body is connected to the forward threaded rod body.

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] Embodiment 1

[0027] like Figure 1-2 As shown, a rod loading robot for an extrusion heating furnace includes a main frame 1, a spring adjustment mechanism 2 installed above the main frame 1, and a clamping mechanism 3 installed below the main frame 2 for clamping and fixing a metal rod. A main frame slide rail pair 11 is fixedly installed at a portion below the main frame 1 corresponding to the clamping mechanism 3 by screws.

[0028] The spring adjustment mechanism 2 includes a spring adjustment guide rail pair 21 fixedly installed with the main frame 1 by screws, a limit support seat 22 located at both ends of the spring adjustment guide rail pair 21 and fixedly installed with the main frame 1 by screws, a fixed rod 23 fixedly installed with the limit support seat 22, a connecting seat 24 mounted on the fixed rod 23 and capable of sliding along the fixed rod 23, and an adjustment spring 25 mounted on the fixed rod 23 and located on both sides of the connecting seat 24.

[0029] Specifically, during use, when the position of the metal rod deviates, the clamping mechanism 3 also deviates after clamping the metal rod. At this time, the adjustment spring 25 adjusts the connecting seat 24 so that the clamping mechanism 3 can align with the metal rod placed on the material rack, thereby avoiding production accidents caused by metal rod clamping deviation.

[0030] The clamping mechanism 3 includes a trapezoidal mounting frame 31 welded and fixed on both sides of the main frame 1, a driving motor 32 installed on the side of one of the trapezoidal mounting frames 31, a transmission screw 33 mounted on the trapezoidal mounting frame 31 and connected to the driving motor 32, a support box 34 installed in the central part below the main frame 1 and used to protect the transmission screw 33, and a first chuck 35 and a second chuck 36 located on both sides of the support box 34 and mounted on the transmission screw 33.

[0031] In this solution, the design of the trapezoidal mounting frame 31 provides a solid support that can withstand greater force and heat, and is suitable for the working environment of the rod on the extrusion heating furnace. The use of the transmission screw 33 can achieve fine linear motion control, and cooperate with the drive motor 32 to achieve precise position adjustment of the first chuck 35 and the second chuck 36, thereby achieving precise clamping of the metal rod. In addition, the first chuck 35 and the second chuck 36 on the transmission screw 33 can be adjusted according to the size of the metal rod to ensure the clamping force, thereby achieving reliable clamping of the metal rod.

[0032] A connecting seat slider 241 is fixed to the lower end of the connecting seat 24 by screws. The connecting seat slider 241 is movably assembled with the spring adjustment guide rail pair 21 to facilitate the connecting seat 24 to slide left and right under the adjustment of the adjustment spring 25.

[0033] Specifically, by movably assembling the connecting seat slider 241 and the spring adjustment guide rail pair 21, the connecting seat 24 can slide left and right under the action of the adjustment spring 25. This design provides great flexibility and can accurately adjust the position according to work needs. Although the connecting seat 24 can slide left and right, it is fixed to the spring adjustment guide rail pair 21 by screws, so it remains stable during the movement without shaking or deviation.

[0034] In addition, since the connecting seat 24 can slide on the spring-adjustable guide rail pair 21, it can be fine-tuned according to the actual position of the metal rod to ensure that the clamping mechanism can accurately align the metal rod placed on the material rack. Under the action of the spring, the connecting seat 24 can automatically slide left and right to improve the automation of the operation, reduce human errors, and improve production efficiency and product quality.

[0035] The driving motor 32 is fixed with a motor fixing seat 321 by screws, a driving gear 322 mounted on the output end of the driving motor 32 , and a driven gear 323 meshing with the driving gear 322 and mounted on the transmission screw rod 33 .

[0036] Specifically, the motor fixing base 321 is directly fixed to the driving motor 32 by screws, so that the connection between the motor and the transmission system is tighter and more integrated, saving space and enhancing the compactness of the overall structure. The meshing relationship between the driving gear 322 and the driven gear 323 ensures that the torque is smoothly and continuously transmitted from the motor to the transmission screw 33, thereby providing a stable clamping force.

[0037] The support box 34 is provided with a fixed bearing seat 341 for supporting the transmission screw 33 . A limit sensor 342 is also provided on one side of the support box 34 for sensing the moving distance of the second clamp 36 .

[0038] Specifically, the fixed bearing seat 341 is used to support the transmission screw 33, ensuring the stability and smoothness of the transmission screw during movement. This stable support reduces vibration and noise during transmission and prolongs the service life of the equipment. The setting of the limit sensor 342 enables the system to accurately sense the moving distance of the second clamp 36 (first clamp 35), which is very critical for ensuring the precise positioning of the clamping mechanism, thereby improving the accuracy and repeatability of the operation.

[0039] In addition, the limit sensor 342 can also be used as a safety measure to prevent the first clamp 35 and the second clamp 36 from exceeding a preset working range, thereby avoiding possible mechanical failures or operational accidents.

[0040] The first chuck 35 includes a chuck body 351 , a nut 352 mounted on the chuck body 251 and sleeved on the transmission screw 33 , and a chuck slider 353 welded above the chuck body 251 and assembled with the main frame slide rail pair 11 .

[0041] Specifically, the chuck body 351 provides a solid foundation for the entire chuck, ensuring stability and reliability during the clamping process, and the nut 352 is mounted on the transmission screw 33, so that the chuck body 351 can perform precise linear movement as the transmission screw rotates. This design can achieve precise control of the chuck position, thereby improving the positioning accuracy when clamping the metal rod.

[0042] like Figure 3 As shown, the transmission screw 33 includes a forward threaded rod body 331 and a reverse threaded rod body 332 connected to the forward threaded rod body 331. A forward threaded rod joint 3311 is welded to the portion where the forward threaded rod body 331 and the reverse threaded rod body 332 are connected, and a reverse threaded rod joint 3321 is welded to the portion where the reverse threaded rod body 332 and the forward threaded rod body 331 are connected.

[0043] Specifically, the forward threaded rod joint 3311 and the reverse threaded rod joint 3321 are docked and fixed. Driven by the driving motor 32, the forward threaded rod body 331 and the reverse threaded rod body 332 rotate simultaneously, controlling the first chuck 35 and the second chuck 36 to move closer or farther away, thereby clamping or loosening the metal rod.

[0044] The above-mentioned embodiments of the utility model are not intended to limit the protection scope of the utility model, and the implementation methods of the utility model are not limited to these. All other various forms of modifications, replacements or changes made to the above-mentioned structure of the utility model based on the above-mentioned contents of the utility model, in accordance with the common technical knowledge and customary means in the field, without departing from the above-mentioned basic technical ideas of the utility model, should fall within the protection scope of the utility model.
