DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] See also Figure 1-Figure 3 As shown, the embodiment of the present invention includes: A simple clamping device for screw connection comprises a screw rod 3 motor assembly, a jaw assembly and a limit assembly.

[0014] The screw rod 3 motor assembly is horizontally arranged, and includes a motor base 1, a coupling 2, a screw rod 3, a mounting platform 4 and a support base 5.

[0015] An installation platform 4 is provided between the motor base 1 and the support base 5, the coupling 2 is provided in the motor base 1, one end of the screw rod 3 is connected to the coupling 2, and the other end is connected to the support base 5, and the motor is provided to drive the coupling 2 to drive the screw rod 3 to rotate.

[0016] The jaw assembly includes a movable jaw 6 , a fixed jaw 7 , a movable quick-change jaw 8 , a fixed quick-change jaw 9 and a quick-change chuck insert 10 .

[0017] The fixed jaw 7 is fixed on the mounting platform 4 on one side of the support seat 5, and the movable jaw 6 is slidably set on the base of the fixed jaw 7 and the bottom is correspondingly connected to the screw nut on the screw 3. The movable jaw 6 is driven close to or away from the fixed jaw 7 by the screw nut to ensure smooth and accurate opening and closing of the jaws.

[0018] The movable quick-change clamp 8 is bonded to the top of the mounting side of the movable jaw 6, and the fixed quick-change clamp 9 is bonded to the top of the mounting side of the fixed jaw 7. The movable quick-change clamp 8 or the fixed quick-change clamp 9 is also provided with a plurality of quick-change chuck inserts 10 at intervals on the connection side. The movable quick-change clamp 8 and the fixed quick-change clamp 9 are made of polyurethane. The quick-change chuck insert 10 is provided in a hollow cylindrical structure for fast positioning and guiding of the screw 17. The movable quick-change clamp 8, the fixed quick-change clamp 9 and the quick-change chuck insert 10 can be made according to different specifications of the screw 17, and can be easily replaced after being worn.

[0019] The limiting assembly is arranged on the side of the jaw assembly and is used to limit the front side of the inner guide rail 18 of the jaw, and includes an air pump 11, a telescopic cylinder 12, a guide plate 13, a slide rod 14, an acrylic plate 15, a connecting plate 16 and a pin 17.

[0020] The air pump 11 is arranged on the front side of the fixed jaw 7, and the telescopic cylinder 12 is fixed on the top of the air pump 11 obliquely upward and parallel to the front side of the fixed jaw 7. The air pump 11 is used to supply air to the telescopic cylinder 12, and the telescopic cylinder 12 is used to provide a driving force for the movement of the limiting structure.

[0021] The guide plate 13 is parallel to the front side of the fixed jaw 7 and is fixed to the fixed jaw 7 by a locking piece 18. The guide plate 13 is provided with a 7-shaped guide groove 19 on the installation side of the fixed jaw 7. The driving end of the telescopic cylinder 12 is correspondingly connected to the slide rod 14 slidably set in the guide groove 19. The driving end of the telescopic cylinder 12 is also connected to a connecting plate 16 parallel to the front side of the fixed jaw 7. The connecting plate 16 is fixed with an acrylic plate 15 on one side of the fixed jaw 7 by a pin 17. The acrylic plate 15 moves to the required limit position on the front side of the jaw under the drive of the telescopic cylinder 12.

[0022] Before work, the jaws are opened a certain distance (slightly larger than the width of the guide rail 21 and the mounting plate 22), and the guide rail 21 is placed into the jaws from the rear side of the device. At this time, the telescopic cylinder 12 in the limit assembly is located at the leftmost high position to ensure that the acrylic plate 15 limits the movement of the guide rail 21 in the front and rear directions. The mounting plate 22 is placed above the guide rail 21 from the rear side, and the holes are aligned. When the mounting plate 22 and the guide rail 21 are placed, the motor drives the movable jaw 6 to move close to the fixed jaw 7. When it moves to an appropriate distance (slightly larger than the screw nut size of the screw 20), the screw 20 is placed in the quick-change chuck insert 10, and the motor continues to drive the movable jaw 6 to continue to reduce the distance between it and the fixed jaw 7 until the screw 20 is clamped. At this time, the screw 20 is tightened manually. After the screw 20 is tightened and installed, the telescopic cylinder 12 moves backward and downward along the slide track to remove the limit baffle assembly. After the movable jaw 6 and the fixed jaw 7 are separated, the connected guide rail 21 and mounting plate 22 are taken out from the side, and this reciprocating process is repeated.

[0023] To sum up, the simple clamping device for screw connection pointed out in the present invention ensures that the screw connection installation between the plate and the guide rail is more reliable, greatly improves the work efficiency of screw installation and the accuracy of installation positioning, and has a reasonable structural design, is suitable for the installation of screw holes of different specifications, has reliable clamping, is easy to install and maintain, and is convenient to use.
