[0018] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0019] Embodiment:

[0020] Please refer to Figs. 1 to 3 The present embodiment proposes a centering aid for the press head of a press and the workbench, which is mainly used for correcting the position of the tooling 3 on the workbench 2 relative to the press head 1 of the press. The tooling 3 is movably placed on the workbench 2, for example, the tooling and the workbench can be detachably connected by means such as screws. The centering aid mainly comprises a centering pin 4, a laser pen 5 and an intermediate body 6. The centering pin can be made of high-strength and wear-resistant metal material, which can ensure that the accuracy will not be affected by wear during long-term use. The tail of the centering pin 4 is detachably connected to the press head 1, and the installed centering pin 4 assumes an almost vertical posture, and the head end of the centering pin 4 forms a centering point 41 at the center. The intermediate body 6 is usually designed in a cylindrical shape, but it can also be other shapes. The intermediate body 6 plays a role in fixing and assembling the laser pen 5 to the tooling 3, that is, the laser pen 5 is movably embedded in the head end of the intermediate body 6, and the irradiation head end of the laser pen 5 is directed towards the centering pin 4, and the other end of the intermediate body 6 is detachably connected to the tooling 3. After installation, the laser pen 5 needs to ensure that the irradiation direction of its light beam is consistent with the length direction of the centering pin 4 above, that is, parallel. The position of the tooling 3 is adjusted by the corresponding state of the light spot of the laser pen 5 and the centering point 41. Specifically, the position of the tooling 3 on the workbench 2 is adjusted so that the light spot of the laser pen 5 almost coincides with the centering point 41 on the centering pin 4. At this time, it can be indicated that the press head 1 of the press and the tooling 3 have been accurately centered, and subsequent press operation can be performed.

[0021] In the present embodiment, a cross head groove 42 in the shape of a cross is designed at the head end of the centering pin 4 at the center position, and the center of the cross head groove 42 corresponding to the center of the centering pin 4 is defined as the centering point 41. Of course, the cross head groove can also be other shapes, such as triangular shape, circular shape, etc., as long as the center can be determined as the centering point. The cross head groove designed in a special shape can facilitate the staff to quickly identify the center of the centering pin during centering operation, and clearly mark the centering point.

[0022] A circle of outer layer threaded part 43 can be designed on the tail outer wall of the centering pin 4, and the tail of the centering pin 4 is screwed into the press head 1 of the press machine, and the centering pin 4 is movably installed on the press head 1 of the press machine through threaded connection, so that the centering pin of corresponding specification can be replaced according to the model of the press machine, and the installation of the centering pin can be adapted.

[0023] In the embodiment, an installation groove 61 is formed in the middle of the top end of the intermediate body 6, and the installation groove 61 has a certain depth and can be tightly inserted with the laser pen 5, so that the laser pen 5 can be kept in a stationary state after installation, and the irradiation beam of the laser pen 5 can be basically consistent with the length direction of the centering pin 4.

[0024] The laser pen 5 is separated from the bottom end of the installation groove 61 by the partition 51, so that the laser pen 5 cannot be pulled out due to excessive tight connection between the laser pen and the installation groove.

[0025] It should be noted that when the laser pen 5 is slidably inserted into the installation groove 61 of the intermediate body 6, the irradiation head end of the laser pen 5 is exposed outward from the top of the installation groove 61, so that the laser pen can be pulled out from the installation groove through the exposed laser pen head end part.

[0026] In the embodiment, the tooling 3 has a cavity 31, the intermediate body 6 can be tightly inserted into the cavity 31 and kept in a nearly vertical state, so that the intermediate body can be stably assembled, and the intermediate body of corresponding specification can be replaced according to the model of the tooling, so that the installation of the laser pen can be adapted.

[0027] The positioning hole 32 is recessed in the bottom end surface of the cavity 31, and the positioning pin 62 corresponding to the position of the positioning hole 32 is protruded from the bottom of the intermediate body 6, so that the intermediate body 6 can be accurately inserted into the cavity 31 of the tooling 3, and the positioning effect is also achieved to a certain extent.

[0028] The above only describes some embodiments of the present application. Those skilled in the art can make some modifications and improvements without departing from the inventive concept, and these all belong to the protection scope of the present application.
