[0010] The beneficial effects of this utility model are as follows: In this utility model, an automatic torque gun and a robotic arm are installed via a torque gun and a robotic arm fixing plate. The automatic torque gun is connected to the screwdriver bit. When the robotic arm operates automatically, it drives the torque gun and the screwdriver bit together. When the screwdriver bit tightens the bolt, it passes through the gun sleeve. Due to the clearance fit between the gun sleeve and the screwdriver bit, after the screwdriver bit retracts to its highest point during the downward pressing process, the rounded corner at the bottom of the gun sleeve makes clearance fit with the bolt head, ensuring that the bolt and the screwdriver bit are always in a concentric state during the operation of the robotic arm. This improves the positioning accuracy of the bolt and the screwdriver bit and reduces the probability of bolt failure. This utility model is applicable to the positioning of Torx bolts and Torx screwdriver bits, as well as the positioning of corresponding bolts and screwdriver bits such as external hexagonal bolts and external hexagonal bolt bits.

[0011] Preferably, the mounting plate with the holster is locked to the positioning plate, which makes the structure easy to disassemble and facilitates the replacement of holsters of different sizes, so that the holster can be matched with the size of the bolt to be tightened.

[0012] Preferably, the mounting plate is connected by two bolts to make the holster more stable.

[0013] Preferably, a knob is provided on the locking bolt to facilitate manual removal of the mounting plate, making the replacement of the holster more convenient and quick.

[0014] Preferably, the torque gun and the robot arm mounting plate adopt an L-shaped structure, the automatic torque gun can be installed on a horizontal plate, and the robot arm can be installed on a vertical plate. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 4 As shown, an embodiment of the present invention provides a tooling for improving the accuracy of automatic bolt locking and cap insertion. It includes a horizontally positioned positioning plate 2 and a gun sleeve 1 fixed on the top of the positioning plate 2. The gun sleeve 1 adopts a cylindrical structure with openings at the top and bottom. The positioning plate 2 has a bit insertion hole that communicates with the inside of the gun sleeve 1 and is concentrically arranged. The bit insertion hole allows the bit 5 to be inserted downward into the gun sleeve 1, and the bit 5 and the gun sleeve 1 are in clearance fit. The inner side of the lower end face of the gun sleeve 1 is provided with a rounded corner 1.1 that is in clearance fit with the bolt head of the bolt to be tightened. A torque gun and a robot arm fixing plate 4 are fixedly connected to the top surface of the positioning plate 2.

[0022] A mounting plate 6 is fixedly connected to the top of the holster 1. The mounting plate 6 has holes concentric with the holster 1 and with the same inner diameter. The mounting plate 6 is fixedly connected to the positioning plate 2 by locking bolts. There are two locking bolts, which are symmetrically arranged on both sides of the bit insertion hole. Each locking bolt is equipped with a locking knob 3.

[0023] The torque gun and robot arm mounting plate 4 is an L-shaped mounting plate used to mount the torque gun and robot arm. The L-shaped mounting plate includes a vertical plate and a horizontal plate that are vertically fixed together. The vertical plate is perpendicular to the positioning plate, and the horizontal plate is parallel to the positioning plate. The upper surface of the positioning plate 2 is provided with a mounting groove 7, which is used for the vertical plate of the L-shaped mounting plate to be inserted into. The vertical plate is fixedly connected to the positioning plate 2 by connecting bolts.

[0024] In use, the automatic torque gun (not shown in the attached diagram) is mounted on the horizontal plate of the torque gun and the robotic arm fixing block 4, and the robotic arm (not shown in the attached diagram) is mounted on the vertical plate of the torque gun and the robotic arm fixing block 4. The automatic torque gun is connected to the bit 5. When the robotic arm operates automatically, it drives the torque gun and the bit together. When tightening the bolt, the bit passes through the gun sleeve 1, which has a clearance fit with the bit. During the downward pressing process, after the bit retracts to its highest point, the rounded corner at the bottom of the gun sleeve 1 has a clearance fit with the bolt head, ensuring that the bolt and bit are always in a concentric state during the operation of the robotic arm. This improves the positioning accuracy of the bolt and bit and reduces the probability of bolt failure. This utility model is applicable to the positioning of Torx bolts and Torx bits, as well as the positioning of corresponding bolts and bits such as external hexagonal bolts and external hexagonal bits.

[0025] The mounting plate with the holster is threadedly fixed to the positioning plate using a locking bolt with a knob. The mounting plate and positioning plate are easy to disassemble, making it convenient to remove the holster when tightening bolts of different sizes and replace it with a holster that is compatible with different bolt sizes.

[0026] While embodiments of the present invention have been described in detail above, the invention is not limited to the embodiments described above. The scope of the invention as defined by the appended claims includes all equivalent substitutions and variations.
