Description

Technical Field

[0001] The utility model relates to the technical field of industrial robots, in particular to an industrial robot which is convenient for replacing a clamp head. Background Art

[0002] With the continuous development of science and technology, the number of robots used in industry is increasing, and the scope of application is becoming more and more extensive. Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices for the industrial field. They can automatically perform work and rely on their own power and control capabilities to achieve various functions. A forging robot is an automated device that imitates some human actions and completes functions such as loading and unloading, and transfer between workstations according to pre-set programs, trajectories or other requirements. It is usually a forging manipulator that works at various stages of the forging process. Compared with manual labor, forging robots have high working efficiency and good safety performance, which can effectively reduce production costs and improve product quality. In the prior art, an industrial forging robot that is easy to replace the clamp head is disclosed in the announcement number CN218195230U. When disassembling the clamp head, this device needs to squeeze the multiple groups of card blocks arranged around it to shrink toward the center at the same time. Since the card blocks are located on the inner side of the shell and the inner area of ​​the shell is relatively narrow, this makes it inconvenient for the staff to squeeze the multiple groups of card blocks arranged around it with their palms at the same time.

A fastening bolt 10 is connected, a through hole 11 is provided on the surface of the mounting block 2, a through hole 2 12 is provided on the top of the mounting block 2, and the through hole 2 12 extends downward into the inner cavity of the through hole 11, a telescopic component 13 is provided at the bottom of the inner cavity of the through hole 11, and limit rods 14 are symmetrically fixedly connected to both ends of the telescopic component 13, and a vertical plate 15 is symmetrically fixedly connected to the top of the inner cavity of the through hole 11, a fixing component 16 that cooperates with the fixing groove 7 is slidably provided on the vertical plate 15, and a limit groove 17 that cooperates with the limit rod 14 is provided on one side of the bottom of the fixing component 16.

[0028] Furthermore, the telescopic assembly 13 includes a sliding rod 131 fixedly mounted on the bottom of the inner cavity of the through hole 11, a sleeve 132 is slidably arranged on the top of the sliding rod 131, a mounting plate 133 is fixedly connected to the top of the sleeve 132, a spring 134 is connected between the mounting plate 133 and the bottom of the inner cavity of the through hole 11, a column 135 is fixedly connected to the top of the mounting plate 133, and a top plate 136 is fixedly connected to the top of the column 135. When installing the pliers head assembly 3, first place the mounting block 2 directly below the connecting rod 6, then move the mounting block 2 upward, the connecting rod 6 passes through the through hole 11 and enters the through hole 2 12, and then continue to move the mounting block 2 in the direction of the connecting rod 6, so that the connecting rod 6 squeezes the top plate 136, and the set top plate 136 drives the column 135, the mounting plate 133, and the sleeve 132 to move downward. At this time, the spring 134 is forced to shrink, and the mounting plate 133 moving downward at the same time drives the limit rod 14 to move downward, so that the limit rod 14 disengages from the limit groove 17.

After the limit rod 14 is disengaged from the limit groove 17, the limit rod 14 no longer limits the cross block 162. After losing the constraint of the limit rod 14, the set fixing rod 161 is inserted into the fixing groove 7 on the side wall of the connecting rod 6 under the action of the elastic force of the second spring 163. The mounting block 2 is preliminarily positioned with the help of the fixing rod 161, and then the fastening bolt 10 is connected to the threaded hole 1 5 and the threaded hole 2 9, thereby completing the installation of the clamp head assembly 3; when the clamp head assembly 3 needs to be disassembled, the staff first removes the fastening bolt 10, and then pushes the symmetrically arranged cross block 162 in the opposite direction until the fixed end of the fixing rod 161 is disengaged from the fixing groove 7, so as to release the positioning of the fixing rod 161 on the connecting rod 6, and then moves the mounting block 2 downward until the connecting rod 6 is disengaged from the through hole 2 12.

[0030] The top of the limiting rod 14 is inserted into the limiting groove 17, so that when the limiting rod 14 is forced to move downward, the limiting rod 14 is fixed by the limit of the horizontal block 162. The initial state of the second spring 163 is a stretched state, so that after the limiting rod 14 releases the limit fixation of the horizontal block 162, the second spring 163 drives the fixing rod 161 to separate from the fixing groove 7 under the action of its own elastic force.

[0031] In addition, a pressing groove 18 is provided on the surface of the cross block 162 , and the pressing groove 18 is provided to facilitate the staff to insert their fingers into the pressing groove 18 to push the cross block 162 to move.

At this time, the spring 134 is forced to shrink, and the mounting plate 133 moving downward drives the limit rod 14 to move downward, so that the limit rod 14 is separated from the limit groove 17, so as to release the limit constraint of the limit rod on the cross block 162. After losing the constraint of the limit rod 14, the fixed rod 161 is inserted into the fixed groove 7 on the side wall of the connecting rod 6 under the action of the elastic force of the spring 2 163. With the help of the fixed rod 1 61 performs preliminary positioning of the mounting block 2, and then connects the fastening bolt 10 to the threaded hole 1 5 and the threaded hole 2 9, thereby completing the installation of the pliers head assembly 3; when the pliers head assembly 3 needs to be disassembled, the staff first removes the fastening bolt 10, and then pushes the symmetrically arranged cross block 162 in the opposite direction until the fixed end of the fixing rod 161 is disengaged from the fixing groove 7, thereby releasing the positioning of the fixing rod 161 on the connecting rod 6, and then moves the mounting block 2 downward until the connecting rod 6 is disengaged from the through hole 2 12. When disassembling the pliers head assembly 3, the staff only needs to insert the thumb and index finger into the two groups of pressure grooves 18 respectively and push the symmetrically arranged cross block 162 in the opposite direction. Since the through hole 11 has a larger space and the symmetrically arranged pressure grooves 18 are located on the same side, the operation difficulty of the device is relatively low.
