It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model discloses a specific implementation of an automatic screw driving device with an electric gun automatic torque calibration function, see Figure 1 to Figure 2 The automatic screw driving device includes a frame 1, a contoured jig 2, an electric gun calibration mechanism 3 and a screw fastening mechanism 4.

[0023] In this embodiment, the top surface of the frame 1 is provided with a mounting frame 10 and a profiling jig 2, and the profiling jig 2 is located in the mounting frame 10. Specifically, the mounting frame 10 includes a left side plate 11, a right side plate 12, a back plate 13 and a top plate 14, the back plate 13, the left side plate 11 and the right side plate 12 are all vertically fixedly mounted on the top surface of the frame 1, the left side plate 11 and the right side plate 12 are respectively located on the left and right sides of the back plate 13, and the top plate 14 is covered on the top of the left side plate 11, the right side plate 12 and the back plate 13, so that an operation window is formed on the front side of the mounting frame 10, and workers can put the products to be processed into the profiling jig 2 through the operation window.

[0024] In order to improve the safety of the screw driving equipment, a safety grating 15 is also fixedly installed on the top surface of the frame 1. The safety grating 15 is enclosed at the edge of the top surface of the frame 1. Specifically, the area enclosed by the safety grating 15 is located at the front side of the left side plate 11, the front side of the right side plate 12 and the lower side of the top plate 14. Specifically, there are three groups of safety gratings 15, the grating safety level is level four, and a double-circuit safety connection is adopted. The first group is placed on the front side of the left side plate 11, the second group is placed on the front side of the right side plate 12, and the third group is placed between the first group and the second group. The three groups of safety gratings 15 are arranged in a U shape to prevent human hands from breaking into the working area during the operation of the equipment to cause safety hazards.

[0025] In this embodiment, the profiling jig 2 is slidably mounted on the top surface of the frame 1. Specifically, a slide plate 21 fixed to the profiling jig 2 is provided at the bottom of the profiling jig 2, and a pair of slide rails 22 fixedly mounted on the frame 1 and slidingly matched with the slide plate 21 are provided below the slide plate 21. It can be understood that a slider slidingly matched with the slide rail 22 is provided below the slide plate 21, and the slider is fixedly connected to the slide plate 21. A rotatable screw rod 23 is provided between the two pairs of slide rails 22, and a servo motor 24 is also provided between the two pairs of slide rails 22. The output shaft of the servo motor 24 is fixedly connected to the screw rod 23 and can drive the screw rod 23 to rotate. A sleeve slidingly matched with the screw rod 23 is provided on the outer peripheral side of the screw rod 23, and the sleeve is fixedly connected to the slide plate 21. When the screw rod 23 rotates, the sleeve can reciprocate along its axial direction on the screw rod 23. During operation, the servo motor 24 drives the screw rod 23 to rotate, and the screw rod 23 drives the sleeve to slide along its axial direction. Since the sleeve is fixed to the slide plate 21, the sleeve drives the slide plate 21 to slide along the axial direction of the screw rod 23, that is, the sleeve drives the slider on the slide plate 21 to move back and forth along the slide rail 22.

[0026] In order to improve applicability and convenience, the top surface of the frame 1 is also provided with a quick aviation plug located on the side of the electric gun calibration mechanism 3. The quick aviation plug is also a quick aviation plug or a quick aviation socket. The quick aviation plug can be fixed on the slide plate 21 so that the screw driving equipment supports the quick mold change function to meet the rapid switching production of different products. The contoured jig 2 of different specifications customized according to the product structure can be quickly assembled and disassembled on the slide plate 21. The quick aviation plug facilitates the electrical connection of the jig. The mold change time of the whole set of jigs can be controlled within three minutes, meeting the requirements of frequent mold changes in the lean production process of the automotive industry.

[0027] As a further improvement, the electric gun calibration mechanism 3 is fixedly mounted on the top surface of the frame 1, or the electric gun calibration mechanism 3 can be fixedly mounted on the slide plate 21, as long as it is located on the side of the profiling mold 2 and does not hinder the normal operation of the profiling mold 2. Figure 2The electric gun calibration mechanism 3 includes a fixed seat 31, a torque calibrator 32 and a pressure plate 33. The fixed seat 31 is provided with a slot, the torque calibrator 32 is placed in the slot, and the working end of the torque calibrator 32 extends upward from the slot. The pressure plate 33 is fixedly installed on the top surface of the fixed seat 31, and the middle part of the pressure plate 33 is located above the torque calibrator 32. It can be understood that part of the pressure plate 33 spans the upper side of the notch of the slot, that is, part of the pressure plate 33 blocks the notch of the slot, so that the torque calibrator 32 can be quickly disassembled and assembled by removing the pressure plate 33, which is convenient for replacement or maintenance.

[0028] It should be noted that see Figure 1 As shown, the screw fastening mechanism 4 is slidably mounted in the mounting frame 10, and the screw fastening mechanism 4 includes an electric gun body 41 and a sliding assembly that drives the electric gun body 41 to slide. The sliding assembly is a conventional moving mechanism, and its power source can be electric or pneumatic, as long as it can drive the electric gun body 41 to reciprocate in the vertical, lateral and longitudinal directions.

[0029] Furthermore, in order to improve the convenience of the screw driving device, a main switch assembly 51 is provided on the left side or right side of the frame 1, and a start switch assembly 52 is provided on the front face of the frame 1. The main switch assembly 51 uses a switch with a lockout function to meet the safety requirements during the equipment maintenance process. In addition, a display panel 6 is fixedly installed on the left side panel 11 or the right side panel 12 to facilitate the adjustment of various parameters and the observation of the working status of the screw driving device.

[0030] The working process of the screw driving device of this embodiment is as follows: the operator places the product to be processed in the profiling jig 2, and the operator presses the start switch assembly 52, and the device starts to operate. At this time, the slide 21 of the device moves under the drive of the servo motor 24 and the screw rod 23, and at the same time, the electric gun body 41 of the screw fastening mechanism 4 automatically performs the screw fastening operation on the product according to the preset running track. When the fastening is completed, the slide 21 returns to its original position, the device stops running, and the operator takes the processed product out of the profiling jig 2, and the entire processing process is completed.

[0031] When the electric gun torque is calibrated, the operator operates the display panel 6 to enter the calibration procedure. At this time, the electric gun body 41 of the screw fastening mechanism 4 moves to the top of the electric gun calibration mechanism 3 and docks with the torque calibrator 32 to automatically perform torque calibration. The calibration results can be displayed on the display panel 6. After the calibration is completed, the electric gun body 41 returns to its original position, and the device stops running and enters the standby mode.

[0032] Compared with the prior art, by building an electric gun calibration mechanism 3 into the automatic screw driving equipment, the torque calibration process can be performed on the electric gun body 41 of the screw fastening mechanism 4 without disassembling the electric gun body 41, saving adjustment time, reducing the labor intensity of workers, and solving the problem of inconvenient calibration in the past. The operation is simple, and the calibration is convenient and fast, which greatly facilitates the daily calibration and inspection process, while reducing additional manual operations and the waste of equipment downtime caused by inspection, thereby improving production efficiency.

[0033] Finally, it should be noted that the automatic screw driving device with automatic torque calibration function of an electric gun disclosed in the embodiment of the utility model only discloses a preferred embodiment of the utility model, which is only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
