DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0022] Please refer to Figures 1-5 The utility model provides an embodiment: a multifunctional mechanical arm for robot clamping, including mechanical arm body 1, rotating seat 2, clamping structure 3 and replacement structure 4, the top fixed connection rotating seat 2 of mechanical arm body 1, rotating seat 2 swing joint rotating rod 22, clamping structure 3 includes sliding rail 31, the bottom fixed connection sliding rail 31 of rotating rod 22, the middle bottom of sliding rail 31 swing joint threaded rod 33, the front and rear both ends of sliding rail 31 bottom are all fixed connection limiting rod 34, limiting rod 34 sliding connection sliding rod 35, threaded rod 33 screw connection sliding rod 35, sliding rod 35 sliding connection sliding rail 31, replacement structure 4 includes fixed seat 41, the bottom fixed connection fixed seat 41 of sliding rod 35, fixed seat 41 sliding connection sliding block 42, fixed seat 41 and sliding block 42 all sliding connection pin shaft 43, the bottom fixed connection clamping plate 44 of sliding block 42, through the cooperation of rotating seat 2 and clamping structure 3, can hold the article of different sizes, and can be held from multiple angles, through replacement structure 4, different shape clamps can be quickly replaced, so as to hold the article of different shapes, convenient and fast to use.
[0023] Further, the right side fixed connection motor one 21 of rotating seat 2, the drive shaft fixed connection rotating rod 22 of motor one 21, the right side fixed connection motor two 32 of sliding rail 31, the drive shaft fixed connection threaded rod 33 of motor two 32, motor one 21 and motor two 32 are prior art, are widely used in household appliances, industrial equipment, agricultural equipment, military equipment and vehicles, and will not be described in detail in this paper, motor one 21 and motor two 32 are installed through four fixed bolts.
[0024] Further, the threaded rod 33 is a double-threaded rod, and the threads at the left and right ends of the threaded rod 33 are symmetrical to each other. When the motor 32 drives the threaded rod 33 to rotate, the threaded rod 33 drives the two sliding rods 35 to move synchronously towards the middle or the two ends, thereby realizing the left and right movement of the clamping plate 44.
[0025] Further, the rear end of the pin shaft 43 is provided with a pull ring, and the front end of the pin shaft 43 is provided with a pin. By pulling the pull ring of the pin shaft 43, the pin shaft 43 is pulled out, so that the pin shaft 43 no longer fixes the position of the sliding block 42.
[0026] Further, the outer wall of the clamping plate 44 is fixedly connected with a buffer pad 45, which is made of rubber and has a rough surface. The buffer pad 45 can increase the friction between the clamping plate 44 and the object, and the rough surface can increase the contact area between the buffer pad 45 and the object, thereby improving the stability during clamping. In addition, the elasticity of the buffer pad 45 can prevent the clamping plate 44 from pressing the object and causing damage to the surface of the object.
[0027] Further, the motor 21 and the motor 32 are controlled by the control console, and the motor 21 and the motor 32 are powered by an external power source. The external power source provides power to the motor 21 and the motor 32, and the control console sends control signals to realize the functions of starting, stopping, speed adjustment and rotation direction of the motor 21 and the motor 32.
[0028] Working principle:
[0029] In use, the mechanical arm body 1 is a prior art and will not be described in detail herein. When it is necessary to clamp an object, the motor 32 is turned on to drive the threaded rod 33 to rotate, so that the threaded rod 33 drives the sliding rod 35 to move towards the middle, thereby clamping the object by the sliding rod 35. The stability of the sliding rod 35 during movement is improved by the limiting rod 34. The motor 21 is turned on to drive the rotating rod 22 to rotate, and the rotating rod 22 drives the clamping structure 3 to rotate, thereby realizing clamping at different angles. The combination of the rotating seat 2 and the clamping structure 3 can clamp objects of different sizes from multiple angles, which is more convenient and fast to use and easy to operate. When it is necessary to clamp objects of different shapes, the pin is pulled out to no longer fix the position of the pin shaft 43, the pull ring of the pin shaft 43 is pulled to pull out the pin shaft 43, so that the pin shaft 43 no longer fixes the position of the sliding block 42. The clamping plate 44 is pulled out to pull out the sliding block 42 from the fixing seat 41. At this time, different shaped clamps can be replaced. The structure 4 can quickly replace different shaped clamps, thereby clamping objects of different shapes, which is convenient and fast to use.
[0030] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
