DETAILED DESCRIPTION

[0020] like Figure 1-2 As shown, the utility model provides a mechanical gripper, comprising: a mounting frame 110, four grippers 120 and a rotating connecting member 130, the four grippers 120 are coplanarly arranged on the mounting frame 110, and the clamping center lines of the four grippers 120 are parallel, and the rotating connecting member 130 is used to connect the execution end of the articulated robot 200.

[0021] Compared with the prior art, the mechanical gripper 100 provided by the present invention, when loading and unloading, the two grippers 120 on the same side clamp two bars and move them to the double-station deep hole drilling machine 300, and the other two grippers 120 take away the two workpieces of the double-station deep hole drilling machine 300. Then, under the control of the articulated robot 200, the front two grippers 120 and the rear two grippers 120 exchange positions, and the two bars are placed in the designated stations of the double-station deep hole drilling machine 300 in turn, and then the two workpieces are placed in the designated positions, and the above actions are repeated, thereby completing the loading and unloading of the second station at one time, greatly improving production efficiency.

[0022] In one embodiment, see Figure 2 The overall shape of the mounting frame 110 is a T-shaped structure, and a clamping jaw 120 is fixedly connected to each side of the T-shaped structure, and the bottom end of the T-shaped structure is fixed with two other clamping jaws 120 in parallel. Specifically, two clamping jaws 120 are symmetrically distributed on the left and right, and the other two are adjacent and arranged below, that is, they are divided into two symmetrical groups, and each group is staggered up and down. The two groups exchange positions under the control of the articulated robot 200, and are used to clamp and load materials and remove workpieces respectively. Compared with the general rectangular array and straight line distribution of the four clamping jaws 120, when rotating and changing positions, the overall adjustment angle and rotation cross-section are smaller, so that the position change of the two groups of clamping jaws 120 can be faster and less space is required.

[0023] In one embodiment, see Figure 1The mounting frame 110 includes two parallel plates 111 and a plurality of connecting columns 112 for connecting and supporting the two plates 111. Four clamping jaws 120 and a rotating connecting member 130 are arranged between the two plates 111. Specifically, the plate 111 is made of steel and has a T-shaped shape. The turning point adopts an arc edge transition to enhance the structural strength. The two plates 111 are dispersedly provided with a plurality of positioning holes. The connecting columns 112 are screw sleeves, whose two ends are aligned with the corresponding positioning holes on the two plates 111 and are fastened by screws. The length of the connecting column 112 is the distance between the two plates 111. The four clamping jaws 120 are installed between the two plates 111 and fixed to the two plates 111 by screws. Such an arrangement not only meets the structural strength requirements but also reduces the overall weight. At the same time, the clamping jaws 120 do not protrude laterally, which can reduce the risk of collision.

[0024] In one embodiment, the clamping centerlines of the four clamping jaws 120 are perpendicular to the extended surface of the plate 111. Thus, when the four clamping jaws 120 clamp a bar and a workpiece, the axes of the bar and workpiece are parallel to each other. The four axes are equivalent to the four vertices of an isosceles trapezoid, which facilitates position change to avoid obstacles.

[0025] In one embodiment, the rotating connector 130 includes a connection base 131 and a flange 132 fixed to the connection base 131. The connection base 131 is connected to the top of the mounting frame 110, and the flange 132 is connected to the actuator end of the articulated robot 200. Specifically, the connection base 131 is in the shape of a square column, preferably a hollow column, but can also be a solid column. The connection base 131 is fixed between the two plates 111 by screws or welding and is located on the midline.

[0026] In one embodiment, the clamping jaw 120 is an electric clamping jaw 120 , which has higher stability. Of course, the clamping jaw 120 can also be a pneumatic clamping jaw 120 or an electromagnetic clamping jaw 120 .

[0027] like Figure 3 As shown, the utility model provides a double-station screw sleeve drilling production line, including: a mechanical gripper 100, an articulated robot 200 for controlling the mechanical gripper 100, a double-station deep hole drilling machine 300 and a conveying device for conveying workpieces.

[0028] Specifically, the conveying device conveys the bar material to the front of the double-station deep hole drilling machine 300, and the articulated robot 200 controls the two jaws 120 of the mechanical gripper 100 to clamp the two bar materials from the conveying device. Then, the drilled workpiece is clamped by the other two jaws 120, and the bar material is placed on the work station. Then, the two workpieces are placed on the conveying device and transported to the next link. In this way, the production efficiency is greatly improved.

[0029] In one embodiment, the conveying device includes a loading three-axis truss manipulator 410, a chain conveyor 1 420, a chain conveyor 2 430, and a unloading three-axis truss manipulator 440. Both the loading three-axis truss manipulator 410 and the unloading three-axis truss manipulator 440 are provided with a material rack 460. Specifically, the loading three-axis truss manipulator 410 grabs bar material from the material rack 460 and transfers it to the chain conveyor 1 420, and then transports it to the front of the double-station deep hole drilling machine 300. The drilled workpiece is placed on the chain conveyor 2 430 and transported to the bottom of the unloading three-axis truss manipulator 440. It is then transferred to the material rack 460 by the unloading three-axis truss manipulator 440 for temporary storage.

[0030] In one embodiment, the double-station screw insert drilling production line further includes a sawing machine 500, which is positioned at the end of a conveyor assembly. The conveyor assembly also includes a chain conveyor 3 450, which is used to convey segmented bar stock to the bottom of the loading three-axis truss robot 410. Specifically, the sawing machine 500 divides the long bar stock into small segments of a predetermined length, which are then dropped onto the chain conveyor 3 450. The segments are then transferred via the three-axis truss robot to the material rack 460 or directly to the chain conveyor 1 420, further improving the production efficiency of the production line.

[0031] In one embodiment, two double-station deep hole drilling machines 300 are symmetrically arranged, and the articulated robot 200 is located between the two double-station deep hole drilling machines 300. In this way, the two double-station deep hole drilling machines 300 can cooperate with a group of mechanical grippers 100, the articulated robot 200 and the conveying device, thereby further improving production efficiency.
