DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides the following technical solutions:

[0023] Embodiment 1

[0024] See also Figure 1-4 An industrial robot gripper comprises a main body 1, a clamping mechanism 2 is fixedly connected to the right end of the main body 1, and an anti-falling mechanism 3 is fixedly connected to the upper end of the main body 1.

[0025] The clamping mechanism 2 includes a motor 201, which is fixedly connected to the right end of the main body 1. The output shaft of the motor 201 is fixedly connected to a threaded rod 202. The outer wall of the threaded rod 202 is threadedly connected to a threaded block 203. The lower end of the threaded block 203 is fixedly connected to a clamping plate 204. The right end of the clamping plate 204 is provided with a movable groove 205. The front end of the inner wall of the movable groove 205 is fixedly connected to a motor 206. The output shaft of the motor 206 is fixedly connected to a rotating rod 207. The outer wall of the rotating rod 207 is fixedly connected to a gear 208. The front end of the inner wall of the movable groove 205 is connected by a shaft. The bearing is movably connected to a rotating rod 209, a clamping block 210 is fixedly connected to the outer wall of the rotating rod 209, and a half gear 211 is fixedly connected to the outer wall of the rotating rod 209. By using motor 1 201, motor 206, clamping plate 204, gear 1 208, half gear 211, clamping block 210 and other parts in combination, in actual use, objects of different sizes can be clamped in different ways by controlling the switch of motor 1 201 or motor 2 206, without replacing the chuck, it is convenient and quick to use, and the applicability of the device is enhanced, which saves time and effort.

[0026] Furthermore, the threaded rod 202 is movably connected to the right end of the inner wall of the movable groove 205 through a bearing, and the outer wall of the threaded rod 202 is provided with positive and negative threads. By using the threaded rod 202 in combination with the threaded block 203, during use, the outer wall of the threaded rod 202 is provided with positive and negative threads, so when the threaded rod 202 is rotated, the threaded block 203 on the outer wall of the threaded rod 202 can be synchronously closed or separated, thereby facilitating the clamping of the clamping plate 204.

[0027] Furthermore, the rotating rod 1 207 is movably connected to the rear end of the inner wall of the movable groove 205 through a bearing, and the rotating rod 2 209 is movably connected to the rear end of the inner wall of the movable groove 205 through a bearing. By using the rotating rod 1 207 and the rotating rod 2 209 in combination, the rotation generated by the rotating rod 1 207 during use can be transmitted to the rotating rod 2 209 through the engagement of the gear 1 208 and the gear 2.

[0028] Furthermore, the right end of the threaded rod 202 passes through the left end of the inner wall of the main body 1 and is movably connected to the left end of the inner wall of the main body 1 through a bearing. The lower end of the gear 208 is meshed with the upper end of the half gear 211. By using the gear 208 and the half gear 211, the meshing portion of the gear 208 and the half gear 211 is limited during use, so the clamping angle of the clamping block 210 can also be fine-tuned.

[0029] Furthermore, a movable hole 212 is formed on the outer wall of the threaded block 203, and a fixed rod 213 is movably connected to the inner wall of the movable hole 212. The fixed rod 213 is fixedly connected to the left end of the inner wall of the main body 1, and a stopper 214 is fixedly connected to the front end of the inner wall of the movable groove 205. By using the stopper 214, when the position of the stopper 214 blocks the rotation of the half gear 211 during use, the motor 206 is reversed again to complete the reverse meshing of the half gear 211, thereby completing the reciprocating motion. There are two motors 206, and they rotate synchronously but in opposite directions.

[0030] Embodiment 2

[0031] Combination Figure 1-4 On the basis of the first embodiment, the anti-falling mechanism 3 further comprises a connecting rod 301, the connecting rod 301 is fixedly connected to the upper end of the main body 1, the upper end of the connecting rod 301 is fixedly connected to a magnetic block 302, and the outer wall of the main body 1 is provided with a threaded groove. By using the magnetic block 302, the electromagnet 304 and other parts in combination, in the process of clamping the object, the electromagnet 304 can be energized to make it magnetic and attract the magnetic block 302, so as to protect the main body 1 from falling off due to its loose thread.

[0032] Furthermore, the outer wall of the main body 1 is threadedly connected to the connecting tube 303 through a threaded groove, and the upper end of the inner wall of the connecting tube 303 is fixedly connected to the electromagnet 304. By using the connecting tube 303, the main body 1 can be screwed into the connecting tube 303 through threads, and the combination of the magnetic block 302 and the electromagnet 304 can provide an anti-falling protection for the main body 1.

[0033] In actual operation, when the device is used, when it is necessary to clamp some large objects, the motor 1 201 is first started, so that the output shaft of the motor 1 201 rotates and drives the threaded rod 202 to rotate. Under the limit of the fixed rod 213, the two threaded blocks 203 can only move closer or farther away from each other synchronously. At this time, the clamping plate 204 connected by the threaded plate can clamp a larger object. When it is necessary to clamp some smaller objects, the motor 206 can be started to make the two threaded blocks 203 move closer or farther away from each other synchronously. Motor 206 drives rotating rod 1 207 to rotate, and rotating rod 1 207 drives gear 1 208 to rotate, and gear 1 208 is meshed with half gear 211, so gear 1 208 can drive half gear 211 to rotate, thereby making rotating rod 2 209 connected to the inner wall of half gear 211 rotate, so that clamping block 210 can be closed and clamped, and by installing main body 1 on the inner wall of connecting tube 303 and then energizing electromagnet 304, the anti-falling function of main body 1 is completed.
