[0035] At least one tooling detection sensor 14, arranged on the base 11.

[0036] The tooling fixing device of the present utility model realizes efficient and accurate positioning of the tooling through the tooling positioning pins 12 with different shapes, and effectively avoids the situation where the tooling is installed backwards left and right, front and back, etc. Through the locking devices 13 distributed on the side of the base 11 and including a driving cylinder and a locking part, when the tooling is positioned on the base 11, automatic, efficient and accurate locking of the tooling can be realized. After locking, it is not easy to loosen, ensuring the stability of the tooling. Moreover, the locking devices 13 are fixedly installed on the base 11 to avoid loss. In addition, the tooling detection sensor 14 is used to identify parameters such as the model of the tooling, ensure the accuracy of the tooling, and avoid using the wrong tooling. The tooling detection sensor 14 can be a proximity sensor, but is not limited thereto.

[0037] By adopting the tooling fixing device of the present utility model, rapid and accurate tooling changeover can be realized.

[0038] In some embodiments, the plurality of tooling positioning pins 12 include a positioning pin 12a with a circular cross-section and a positioning pin 12b with a rhombic cross-section. Of course, the cross-sectional shape of the tooling positioning pin 12 is not limited to this, and it can also be square, triangular, elliptical, and so on.

[0039] In some embodiments, the plurality of locking devices 13 include a pair of corner locking devices 13a disposed at the diagonals of the base 11, and each corner locking device 13a includes a rotary drive cylinder 131a and a locking head 132a.

[0040] Through a pair of corner locking devices 13a, the diagonals of the tooling are locked to ensure the stability of the tooling. Among them, the rotary drive cylinder 131a is used to drive the locking head 132a to rotate and lift relative to the base 11 to achieve locking and unlocking of the tooling. The rotary drive cylinder 131a can be communicatively connected to a PLC (Programmable Logic Controller) controller, and the locking and unlocking of the corner locking device 13a can be automatically controlled through a PLC program; alternatively, control buttons can be provided on the rotary drive cylinder 131a to control the operation of the rotary drive cylinder 131a.

[0042] Through a pair of edge locking devices 13b, the opposite sides of the tooling are locked to ensure the stability of the tooling. Among them, the telescopic drive cylinder 131b is used to drive the locking block 132b to extend and retract relative to the base 11 to achieve locking and unlocking of the tooling. The telescopic drive cylinder 131b can be communicatively connected to a PLC controller, and the locking and unlocking of the edge locking device 13b can be automatically controlled through a PLC program; alternatively, control buttons can be provided on the telescopic drive cylinder 131b to control the operation of the telescopic drive cylinder 131b.

[0044] In some embodiments, the tooling fixing device further includes: at least one product detection sensor 15, which is arranged on the base 11 and the product detection sensor 15 is higher than the tooling positioning pin 12. The product detection sensor 15 can be used to detect parameters such as the model of the product installed on the tooling to ensure the accuracy of the product. The product detection sensor 15 is higher than the tooling positioning pin 12 so that after the tooling is installed, the product detection sensor 15 can extend out of the tooling, thereby realizing the detection of the product installed on the tooling.

[0045] In some embodiments, the product detection sensor 15 includes a retaining ring 151 arranged on the base 11 and an inductive sensor 152 arranged in the retaining ring 151.

[0051] By cooperating the bushing with the tooling positioning pin 12, efficient and accurate positioning of the target tooling is achieved, and the situation where the target tooling is installed backwards left and right is effectively avoided. By cooperating the locking device 13 with the pad 23, when the target tooling is positioned on the base 11, automatic, efficient, and accurate locking of the target tooling can be achieved. After locking, it is not easy to loosen, ensuring the stability of the target tooling and protecting the main part of the target tooling from being crushed. In addition, the tooling detection sensor 14 can identify parameters such as the model of the target tooling to ensure the accuracy of the target tooling.

[0052] When the target tooling is no longer needed and needs to be changed, loosen the target tooling through the locking device 13, then remove the target tooling and replace it with a new one, and then lock the new tooling through the locking device 13.

The second spacer block 23b cooperates with the edge locking device 13b, and the edge locking device 13b drives the locking block 132b to press the second spacer block 23b through the telescopic drive cylinder 131b to lock the target tooling.

[0054] In some embodiments, at least one product detection sensor 15 is further provided on the base 11, and a through hole 25 cooperating with the product detection sensor 15 is further formed on the bottom plate 21. The through hole 25 allows the product detection sensor 15 to pass through and extend out to identify the product installed on the bottom plate 21.

[0055] In some embodiments, the tooling assembly further includes any one or more of the following components: a pair of handles 26, arranged on the opposite sides of the bottom plate 21, which can be used to grasp and move the target tooling; a plurality of product positioning pins 27, distributed on the bottom plate 21, for positioning during product installation; a camera window 28, penetrating the bottom plate 21 and the base 11, through which the camera installed on the back of the base 11 can extend to collect relevant images of the product installed on the bottom plate 21.

[0056] Among them, the product positioning pin 27 and the bottom plate 21 can be connected in a detachable manner so as to select a product positioning pin 27 with a suitable size and shape according to the product to be positioned. The handle 26 can be adjusted to a suitable height through the heightening column 260.

[0058] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
