Abstract
Description
Technical Field
[0001] This application relates to the field of gripping equipment technology, and in particular to a precision hardware processing gripping robot. Background Technology
[0002] In the manufacturing and processing of hardware parts, bar stock is a commonly used raw material. Cutting it into appropriate sizes is an essential production process. However, due to its smooth surface, lack of stress points, and long length, existing bar stock is often hoisted and transported using straps. But to maintain the balance of the bar stock, the relative position of the straps needs to be adjusted manually multiple times to ensure that the suspended bar stock remains relatively balanced and does not easily tilt. This results in low efficiency in hoisting and transporting bar stock. Furthermore, the stability of maintaining the balance of the bar stock by adjusting the relative position of the straps is poor. The bar stock is easily affected by external factors during hoisting and transport, which can cause it to become unbalanced and tilt, posing a significant safety hazard.
[0003] Therefore, there is an urgent need for a bar stock gripping robot for hardware processing to solve the defects of existing bar stock handling processes. Summary of the Invention
[0004] This application proposes a precision hardware parts processing gripping robot, which has the advantages of effectively improving the efficiency of bar lifting and handling, being less prone to imbalance and tilting during lifting and handling, and having high safety and reliability. It solves the problem that in order to maintain the balance of bar materials by binding straps, it is necessary to manually adjust the relative position of the binding straps multiple times, which leads to the low efficiency of bar lifting and handling. Furthermore, the stability of maintaining the balance of bar materials by adjusting the relative position of the binding straps is poor, and the bar materials are easily affected by external factors during lifting and handling, which can cause imbalance and tilting.
[0005] To achieve the above objectives, this application adopts the following technical solution: a precision hardware parts processing gripping robot, comprising a support frame fixedly mounted on the middle of the top end of a traveling mechanism, which can then move the support frame to a specific position by moving the traveling mechanism. A set of hydraulic cylinders, connected to a pump station fixedly mounted on the support frame, is pinned to the top of each side of the support frame. A clamping mechanism, pinned to the bottom of one side of the support frame, is provided on the drive shaft of the hydraulic cylinders. Thus, by adjusting the tilt of the two clamping mechanisms, bars of different specifications and sizes can be stably clamped between them, and the walking mechanism can then be used for lifting and transporting. The bar stock includes an outer frame with a semi-circular structure. The middle part of each side of the outer frame is provided with a set of connecting shafts that are pinned to the bottom of the support frame. The top of the inner end of the outer frame is fixedly installed with an ear seat that is pinned to the drive shaft of the hydraulic cylinder assembly. This allows the extension and retraction of the hydraulic cylinder assembly to cause the outer frame to tilt to different degrees. The inner part of the outer frame is movably connected with a locking ring. Under the action of the locking ring, a complete circular component can be formed between the outer frame and the two sets of outer frames to fit the bar stock between them. Then, the bar stock is clamped or released according to the tilt of the outer frame and its locking ring for hoisting and handling operations.
[0006] Furthermore, an inner retaining ring is fixedly installed inside the outer frame by bolts, and the locking ring is movably engaged inside the outer frame by the inner retaining ring. The outer surface of the locking ring is provided with a linkage tooth assembly, and the locking ring engages with the drive motor fixedly installed on the top of the outer frame through the linkage tooth assembly. Thus, when the drive motor is started to rotate forward or reverse, it can drive the locking ring to extend or retract, so that the outer frame can form a complete circular component to fit the bar material into it for hoisting and handling operations.
[0007] Furthermore, a first limiting groove is formed on the outer surface of the inner retaining ring, and a second limiting groove is formed on the inner side of the locking ring to cooperate with the first limiting groove. Thus, with the cooperation of the first limiting groove and the second limiting groove, the inner retaining ring can be stably locked onto the outer frame, and the strength of the movable connection between the inner retaining ring and the outer frame can be effectively enhanced, so that it is not easy to shake during the process of being subjected to force.
[0008] Furthermore, the locking ring is designed as a semi-circular structure, and the included angle between its two ends is greater than 180°, thereby ensuring that the locking ring can completely seal the bottom of the outer frame under the driving action of the drive motor, so as to form a complete circular component.
[0009] Furthermore, the outer frame, the locking ring, and the end face that contacts the bar stock are each provided with a set of rubber pads to effectively reduce frictional damage to the outer surface of the bar stock during the contact process.
[0010] Furthermore, the tilting direction of both sets of clamping mechanisms is set outward relative to the support frame, which can effectively reduce the bearing pressure of the hydraulic cylinder group during the hoisting and handling of bar stock.
[0011] Furthermore, each of the two sets of hydraulic cylinders is equipped with an angle sensor. When lifting and transporting the bar stock, it is necessary to ensure that the deflection angle between the two sets of hydraulic cylinders is the same, so that even if the center of gravity of the bar stock deviates during the lifting and transporting process, it can still maintain a relatively horizontal state.
[0012] The beneficial effects of this invention are as follows:
[0013] This application provides a precision hardware parts processing gripping robot. The clamping mechanism and its structure can utilize the inclination between two sets of outer frames to clamp bar stock of different specifications and sizes and perform hoisting and handling operations. Compared with existing bar stock handling methods, it can effectively improve the efficiency of bar stock hoisting and handling, and is less prone to imbalance and tilting during hoisting and handling, thus having higher safety and reliability.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] like Figure 1 , Figure 2 As shown, a precision hardware parts processing gripper includes a support frame 1 fixedly mounted on a traveling mechanism at the top center. The traveling mechanism moves the support frame 1 to a specific position. A set of hydraulic cylinders 2, connected to a pump station fixedly mounted on the support frame 1, is pinned to the top of each side of the support frame 1. A clamping mechanism 3, pinned to the bottom of one side of the support frame 1, is mounted on the drive shaft of the hydraulic cylinders 2. The clamping mechanism 3 can stably clamp bars 4 of different sizes between the two clamping mechanisms 3 by tilting them, and then perform lifting and handling operations under the movement of the traveling mechanism. Figure 3 As shown, the bar stock 4 includes an outer frame 5 with a semi-circular structure. A set of connecting shafts 7 are respectively provided in the middle of both sides of the outer frame 5 and pinned to the bottom of one side of the support frame 1. An ear seat 6 is fixedly installed on the top of the inner end of the outer frame 5 and pinned to the drive shaft of the hydraulic cylinder group 2. Thus, the extension and retraction of the hydraulic cylinder group 2 can cause the outer frame 5 to tilt to different degrees. A locking ring 10 is movably connected inside the outer frame 5. Under the action of the locking ring 10, a complete circular component can be formed between the outer frame 5 to fit the bar stock 4 between the two sets of outer frames 5. Then, the bar stock 4 is clamped or released according to the tilt of the outer frame 5 and its locking ring 10 for hoisting and handling operations.
[0023] like Figure 3 , Figure 5 As shown, in this technical solution, an inner retaining ring 9 is fixedly installed inside the outer frame 5 by bolts, and the locking ring 10 is movably engaged inside the outer frame 5 by the inner retaining ring 9. The outer surface of the locking ring 10 is provided with a linkage gear set 13, and the locking ring 10 is engaged with the drive motor 8 fixedly installed on the top of the outer frame 5 through the linkage gear set 13. Thus, when the drive motor 8 is started to rotate forward or reverse, it can drive the locking ring 10 to extend or retract, so that the outer frame 5 can form a complete circular component to fit the bar 4 into it for hoisting and handling operations.
[0024] like Figure 4 , Figure 5As shown, in this technical solution, a first limiting groove 11 is provided on the outer surface of the inner retaining ring 9, and a second limiting groove 12 that cooperates with the first limiting groove 11 is provided on the inner side of the locking ring 10. Thus, with the cooperation of the first limiting groove 11 and the second limiting groove 12, the inner retaining ring 9 can be stably locked onto the outer frame 5, and the strength of the movable connection between the inner retaining ring 9 and the outer frame 5 can be effectively enhanced, so that it is not easy to shake during the process of being subjected to force.
[0025] like Figure 3 , Figure 5 As shown, in this technical solution, the locking ring 10 is set as a semi-circular structure, and the included angle between its two ends is greater than 180°, thereby ensuring that the locking ring 10 can completely seal the bottom of the outer frame 5 under the driving action of the drive motor 8, so as to form a complete circular component.
[0026] like Figure 2 , Figure 3 As shown, in this technical solution, the outer frame 5, the locking ring 10 and the end face of the bar 4 that are in contact with each other are provided with a set of rubber pads to effectively reduce the frictional damage to the outer surface of the bar 4 during the contact process.
[0027] like Figure 2 As shown, in this technical solution, the tilting direction of the two sets of clamping mechanisms 3 is set outward relative to the support frame 1, thereby effectively reducing the bearing pressure of the hydraulic cylinder group 2 during the hoisting and handling of the bar material 4.
[0028] In this technical solution, each of the two sets of hydraulic cylinders 2 is equipped with an angle sensor. When lifting and transporting the bar stock 4, it is necessary to ensure that the deflection angle between the two sets of hydraulic cylinders 2 is the same, so that even if the center of gravity of the bar stock 4 is deviated during the lifting and transporting process, it can maintain a relatively horizontal state.
