[0029] like Figures 1 to 3 As shown, according to an embodiment of the utility model, the tooling equipment 100 for assembling and screwing the upper and lower covers of the clock spring mainly includes: a frame 10, a conveying rail 20, a lifting mechanism 30, a screw hole clamping plate 40 and an induction screw gun (not shown) and other components and mechanisms. The conveying rail 20 is configured to convey the upper and lower covers of the clock spring. With the help of the conveying rail 20, the upper and lower covers of the clock spring are conveyed from the previous operating position to an operating position to perform the two-in-one operation of assembling and screwing the upper and lower covers of the clock spring at the operating position; and after completing the two-in-one operation, the upper and lower covers of the clock spring are conveyed from the operating position to the next operating position along the conveying rail 20. Further, the tooling equipment 100 may also include: a tray that can move along the conveying rail 20, wherein the upper and lower covers of the clock spring are placed in the tray to move along the conveying rail 20 (i.e., move into the operating position, and, move out of the operating position).

[0030] According to the embodiments of the present utility model, Figures 1 to 3As shown, the lifting mechanism 30 and the screw hole position card plate 40 are arranged on the frame 10. With the help of the frame 10, the lifting mechanism 30 and the screw hole position card plate 40 are arranged at or near the operating position of the conveying guide rail 20. The lifting mechanism 30 is configured to: when the clock spring upper and lower covers are conveyed to the aforementioned operating position, lift the clock spring upper and lower covers to the target position relative to the conveying guide rail 10 and fix them, so as to perform the assembly operation of the clock spring upper and lower covers and the subsequent screw installation operation. That is, with the help of the lifting mechanism 30, the tray located at the aforementioned operating position and the clock spring upper and lower covers placed in the tray can be raised and lowered relative to the conveying guide rail 20.

[0031] According to the embodiments of the present utility model, Figures 1 to 3 As shown, the screw hole position card plate 40 is configured to cooperate with the lifting mechanism 30 to perform assembly operations and screw installation operations on the upper and lower covers of the clock spring in the operating position. Specifically, the screw hole position card plate 40 is configured to be switchable between a first position and a second position. When switched to the first position, the screw hole position card plate 40 is located above the upper and lower covers of the clock spring in the operating position, so as to cooperate with the lifting mechanism 30 to perform assembly operations and screw installation operations on the upper and lower covers of the clock spring in the operating position; and when switched to the second position, the screw hole position card plate 40 is removed from above the upper and lower covers of the clock spring in the operating position.

[0032] In addition, in the illustrated exemplary embodiment, the tooling equipment 100 further includes: a slide rail disposed on the frame 10. The screw hole position clamping plate 40 is slidably disposed on the slide rail, and can be switched between the first position and the second position in a sliding manner relative to the slide rail. In other embodiments not shown in the drawings, any other suitable manner may be used to achieve the switching of the screw hole position clamping plate 40 between the first position and the second position.

[0033] According to the embodiments of the present utility model, Figures 4 to 5 As shown, specifically, the screw hole position card plate 40 has a screw hole position 41, a pressing pin member 42 and a button 44. The screw hole position 41 is used to achieve accurate positioning of the screw during the screw installation operation. The pressing pin member 42 is used to press against the surface of the upper cover during the upper and lower cover assembly operation to ensure that a certain distance can be maintained between the screw hole position card plate 40 and the upper and lower covers of the spring clock lifted to a specified height by the lifting mechanism 30, so as to prevent the screws from being over-installed during the subsequent screw installation operation. The button 44 is used to start the switching of the screw hole position card plate 40 between the first position and the second position.

[0034] In such Figure 4 and Figure 5In the exemplary embodiment shown, the screw hole card plate 40 has four screw holes 41 (specifically, for example, including 41a, 41b, 41c, and 41d) and four pressing pin members 42 (specifically, for example, including 42a, 42b, 42c, and 42d) evenly arranged in the card plate. Of course, the number and arrangement of the screw holes 41 and the pressing pin members 42 can be designed according to actual needs (such as the specifications and dimensions of the upper and lower covers of the spring clock).

[0035] In addition, according to an exemplary embodiment of the present utility model, Figures 1 to 5 As shown, the screw hole card plate 40 is also formed with a pin 43 (specifically, for example, including 43a and 43b), and another one of the racks 10 is formed with a corresponding socket (not shown). When the screw hole card plate 40 is switched to the first position, the pin 43 is inserted into the socket to maintain the horizontality of the screw hole card plate 40 in the first position. Of course, in other embodiments not shown, the pin can also be formed on the rack 10, and the corresponding socket is formed on the screw hole card plate 40. In addition, in other embodiments not shown, any other suitable method can also be used to maintain the horizontality of the screw hole card plate 40 when it is in the first position.

[0036] In addition, according to an embodiment of the utility model, the induction screw gun is configured to adjust the torque of the induction screw gun according to the model and specification of the upper and lower covers of the spring clock so as to be suitable for different products.

[0037] The utility model provides a two-in-one tooling equipment for clock spring upper and lower covers assembly and screw installation. As the conveying guide rail 20 conveys the clock spring upper and lower covers placed on the pallet to the operating position, the controller of the production line system starts the lifting mechanism 30 to lift the pallet together with the clock spring upper and lower covers on the pallet to a target position with a specified height and fix them. The screw hole position card plate 40 is switched to the first position (when in the first position, the screw hole position 41 in the card plate 40 is aligned with the screw hole position in the clock spring upper and lower covers) to cooperate with the lifting mechanism 30 (for example, the pressing pin member 42 in the card plate 40 abuts against the upper cover surface of the clock spring upper and lower covers to ensure that the clock spring upper and lower covers maintain an appropriate distance from the screw hole position card plate 40) to perform the assembly operation on the clock spring upper and lower covers. After completing the assembly operation, the operator holds the induction screw gun and aligns it with the screw hole 41 on the card 40. The screw gun automatically starts to perform the screw installation operation and accurately drives the screws into the upper and lower covers of the clock spring. In this screw installation operation, the pressing pin member 42 in the card 40 abuts against the upper cover surface of the clock spring upper and lower covers, so that the two maintain an appropriate distance, which can effectively prevent excessive screw installation. Afterwards, under the control of the controller of the production line system, the lifting mechanism 30 descends, so that the clock spring upper and lower covers that have completed the assembly operation and the screw installation operation are transported from the operation position to the next operation position along the conveying guide rail 20, and the next tray is transported into the operation position for the next round of operation.

[0038] Compared with the prior art, the two-in-one tooling equipment for assembling the upper and lower covers of clock springs and installing screws provided by the utility model has at least the following beneficial effects and advantages.

[0039] 1) Improve production efficiency: The two-in-one design reduces the transfer time between workstations, reduces the cycle loss between adjacent workstations, and improves production efficiency.

[0040] 2) Improve product quality: The setting of the screw hole clamp ensures that the screws are accurately driven in, reduces the defective rate, and improves the overall product quality.

[0041] 3) Easy to operate: The design of the pull-out screw hole clamp and the induction screw gun makes the operation easier and faster.

[0042] 4) High flexibility: To meet the screw installation operation requirements of different products, it can be adapted by replacing the screw hole card and adjusting the torque of the screw gun, which has high flexibility.

[0043] Although some embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
