[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-9 A fully automatic electric wellhead includes a wellhead plate 1 with a wellhead formed in the middle, and four adjusting plates 2 arranged in a square pattern along the edge of the wellhead plate 1. (See also...) Figure 3 Each of the adjusting plates 2 has a first guide bar 3 and a second guide bar 4 perpendicular to each other at one corner. The first guide bar 3 extends along one side of the corner of the adjusting plate 2, and the second guide bar 4 extends along the other side of the corner of the adjusting plate 2. The first guide bar 3 of each adjusting plate 2 is slidably connected to the second guide bar 4 of the adjacent adjusting plate 2. Please refer to [link / reference]. Figure 1 as well as Figure 6 The wellhead plate 1 is provided with a driving device 5 connected to each adjusting plate 2. Each driving device 5 drives the corresponding adjusting plate 2 away from or closer to the wellhead of the wellhead plate 1 to adjust the size of the clamping area formed by the four adjusting plates 2.

[0028] By having adjusting plates 2 at the edge of the wellhead plate 1, adjacent adjusting plates 2 are slidably engaged by a first guide bar 3 and a second guide bar 4. Each adjusting plate 2 is driven by a driving device 5 to move towards or away from the center of the wellhead plate 1, thereby automatically adjusting the size of the clamping area. This allows the four adjusting plates 2 to clamp products such as sheets of different profiles, thus distributing and reducing production costs. In this process, the size of the clamping area can be adjusted by a single adjusting plate 2 pushing adjacent adjusting plates 2, or by the four adjusting plates 2 working together. The clamping area can be formed at any position within the wellhead plate 1, offering flexible adjustment and a wide adjustment range.

[0029] Please see Figure 2 In this embodiment, the wellhead edge of the wellhead plate 1 forms a frame 11, and the adjusting plate 2 is movably disposed at the top of the frame 11.

[0030] Please see Figures 4-5 Both the first guide bar 3 and the second guide bar 4 are L-shaped and interlocked. The lower part of the second guide bar 4 extends towards the first guide bar 3 to form a base support 41. The top surface of the base support 41 has a sliding groove 42. The upper part of the first guide bar 3 extends towards the second guide bar 4 to form a top buckle 31. The bottom surface of the top buckle 31 is provided with a slide rail 32 that slides in conjunction with the sliding groove 42. Through the sliding engagement between the slide rail 32 and the sliding groove 42, the relative sliding between the first guide bar 3 and the second guide bar 4 is achieved, thereby adjusting the size of the clamping area of ​​the adjusting plate 2. Furthermore, the slide rail 32 is restricted by the side wall of the sliding groove 42, making it difficult for the slide rail 32 to disengage from the sliding groove 42, thus preventing the first guide bar 3 and the second guide bar 4 from derailing.

[0031] Please see Figure 6 as well as Figure 8 The drive device 5 includes a base plate 51, a servo motor 52, a lead screw drive shaft 53, a ball screw 54, a nut sleeve 55, and a guide assembly 56. The base plate 51 is fixed to the top surface of the wellhead plate 1. The servo motor 52 is horizontally mounted on the top surface of the base plate 51. The lead screw drive shaft 53 is rotatably mounted on the top surface of the base plate 51 via bearings. There are two ball screws 54, which are arranged parallel to each other on the top surface of the base plate 51 and perpendicular to the lead screw drive shaft 53. One end of one ball screw 54 is connected to the output shaft of the servo motor 52 and the lead screw drive shaft 53 respectively through a worm gear transmission structure. The other end of the lead screw drive shaft 53 is connected to the other ball screw 54 through a worm gear transmission structure. The nut sleeve 55 is connected to the ball screw 54 through threads and is connected to the adjusting plate 2 through the guide assembly 56.

[0032] Please see Figure 8The guide assembly 56 includes guide rails 561, sliders 562, connecting plates 563, push shafts 564, and guide wheels 565. Two guide rails 561 are arranged parallel to each other on the top surface of the base plate 51. Sliders 562 are movably mounted on each of the two guide rails 561. Two sliders 562 are connected to each end of the connecting plate 563. Push shafts 564 are upright mounted on the top surfaces of the two sliders 562. (Please refer to...) Figure 9 The bottom surface of the adjusting plate 2 is provided with a limiting groove 2 that extends in the same direction as the length of the connecting plate 563. The top end of the push shaft 564 extends into the limiting groove 2 and the guide wheel 565 is rotatably provided at its extended end. The outer circumferential wheel surface of the guide wheel 565 abuts against the side wall of the limiting groove 2.

[0033] Please see Figure 7 In this embodiment, the top surface of the wellhead plate 1 is provided with a cover 7 that covers the outer periphery of the drive device 5; the top surface of the cover 7 is provided with an elongated hole 71 for the push shaft 564 to pass through.

[0034] When adjusting the clamping area between the adjusting plates 2, the servo motor 52 drives the lead screw drive shaft 53 and the ball screw 54 to rotate. Under the action of the ball screw 54, the nut sleeves 55 on the two ball screws 54 move axially along the ball screw 54, thereby driving the connecting plate 563, slider 562, push shaft 564 and guide wheel 565 to move axially along the ball screw 54 or guide rail 561, so that the push shaft 564 and guide wheel 565 push the adjusting plate 2 to move towards the center of the wellhead plate 1 or away from the center of the wellhead plate 1, thereby realizing the adjustment of the size of the clamping area between the four adjusting plates 2. In this process, since the first guide bar 3 of each adjusting plate 2 is slidably connected to the second guide bar 4 of the adjacent adjusting plate 2, the adjacent adjusting plate 2 will also move in the same direction. At this time, the limiting groove 2 of the adjacent adjusting plate 2 cooperates with the guide wheel 565 to guide the movement of the adjusting plate 2.

[0035] Please see Figures 5-6 Each of the adjusting plates 2 is provided with a pressing mechanism 6 near the edge of the wellhead plate 1. The pressing mechanism 6 includes a support 61, a pressure plate 62, and a swing arm cylinder 63. Several supports 61 are spaced apart along the axial direction of the first guide bar 3. One end of the pressure plate 62 is hinged to one end of the support 61. A fixed plate 64 is hinged to the end of each support 61 away from the pressure plate 62. The swing arm cylinder 63 is mounted on the fixed plate 64, and one end of the piston rod of the swing arm cylinder 63 is hinged to the side of the pressure plate 62. In this embodiment, a protective cover 65 is connected to the fixed plate 64, covering the top and both sides of the swing arm cylinder 63. When the sheet is placed on the four first guide bars 3, several swing arm cylinders 63 drive the pressure plate 62 to swing around the hinge point between it and the support 61 until the pressure plate 62 presses the sheet firmly onto the first guide bar 3, preventing the sheet from loosening or shifting during processing.

[0036] Please see Figure 1 as well as Figure 5 The top surface of the wellhead plate 1 is provided with a plurality of lifting components 8 for lifting the adjusting plate 2. The lifting components 8 include a lifting cylinder 81, a ball seat 82 and a ball 83. The lifting cylinder 81 is installed on the top surface of the wellhead plate 1. One end of the piston rod of the lifting cylinder 81 extends upward relative to the wellhead plate 1. The ball seat 82 is connected to one end of the piston rod of the lifting cylinder 81. A ball socket is opened on the top surface of the ball seat 82. The ball 83 is rotatably installed in the ball socket and supported on the bottom surface of the adjusting plate 2.

[0037] When the drive device 5 drives the adjusting plate 2 to move towards the center of the wellhead plate 1 or away from the center of the wellhead plate 1 and outward, the adjusting plate 2 is first lifted upward by the lifting cylinder 81 to separate the adjusting plate 2 from the wellhead plate 1 vertically, so as to reduce the friction between them and make it easier for the drive device 5 to drive the adjusting plate 2 forward or backward.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
