DETAILED DESCRIPTION

[0022] See also Figure 1 The present invention includes a feeding slide 1, a rotating mechanism 2 and a clamping mechanism 3 which are arranged in sequence from bottom to top. Among them, the feeding slide used for reciprocating feeding is provided with a slide mounting plate 1-4 which can reciprocate linearly, and the rotating mechanism is installed on the slide mounting plate. The rotating mechanism is provided with a rotating base 2-2 and a T-shaped rotating table. The rotating base is fixed on the slide mounting plate. The rotating base does not rotate. The T-shaped rotating table can rotate relative to the rotating base to complete a 180° U-turn of the product part, realize one-time loading, and complete the purpose of processing at both ends of the product part. A clamping mechanism for clamping the product part 4 is installed on the T-shaped rotating table. The clamping mechanism is used to clamp the product part for mechanical processing such as stamping.

[0023] See also Figure 1 , Figure 2The feeding slide is provided with a servo motor 1-1, a guide rail 1-5, a slider 1-6, a base 1-7 and a ball screw assembly 1-3. The mounting seat is the basic component of the feeding slide, and the servo motor is the power component of the feeding slide. The servo motor is fixed to one end of the mounting seat through the servo motor mounting plate 1-2. The servo motor drives the active part of the ball screw assembly, and the driven part of the ball screw assembly is connected to the slide mounting plate. The servo motor rotates, drives the ball screw assembly to move, and drives the slide mounting plate to move linearly. In order to ensure the smooth movement of the slide mounting plate, two guide rails are fixed on the mounting seat, and four sliders are fixed on the lower part of the slide mounting plate. Each guide rail and two sliders slide and cooperate.

[0024] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 , the rotating mechanism is the key mechanism for smoothly realizing the 180° U-turn of the product. The rotating mechanism includes a rotating cylinder 2-1, a driving gear 2-3, a driven gear 2-4, two sets of bearing groups 2-7 and a sealing head 2-8. The T-shaped rotating table is composed of a rotating shaft 2-6 located at the bottom and a supporting platform 2-5 located at the top. The rotating cylinder is fixed to the rotating base through a rotating cylinder mounting plate, and the output end of the rotating cylinder is connected to the driving gear, and the driving gear and the driven gear are meshed. The driven gear is installed on the rotating shaft to drive the rotating shaft to rotate. Considering that the output torque of the rotating cylinder is small, the torque of the rotating shaft can be increased by using a gear pair to transmit the torque. Bearing groups are installed at both ends of the rotating shaft, and each set of bearing groups includes a thrust bearing and a radial bearing respectively. The bearing group bears the axial load and radial load generated during the workpiece processing process, which can avoid large loads acting on the rotating cylinder and causing damage to the rotating cylinder. Bearing mounting holes and rotating shaft mounting holes are provided in the rotating base, and the bearing group and the rotating shaft are assembled in the rotating base. The rotating base is provided with a base air inlet 2-2-1 and a base air outlet 2-2-2, the rotating shaft is provided with two axial air passages 2-6-3, the support table is provided with a support table air inlet 2-5-1 and a support table air outlet 2-5-2, the base air inlet and the base air outlet are respectively connected to the support table air inlet and the support table air outlet through the axial air passages to form an air path leading to the clamping cylinder. The sealing head is located at the lower part of the rotating base, the sealing head is connected to the bottom of the rotating shaft, and a sealing gasket is provided between the sealing head and the rotating shaft. Figure 3 , Figure 4As can be seen, two annular ventilation grooves 2-6-1 are provided on the rotating shaft, and each ventilation groove is provided with an air hole 2-6-4 connected to each axial air channel. Three annular sealing grooves 2-6-2 are also provided on the rotating shaft, and sealing grooves are provided on both sides of each ventilation groove. A sealing ring is provided in each sealing groove, and a sealing contact is formed between the sealing ring and the rotating base, and the two annular ventilation grooves are closed by the sealing ring. The air inlet of the rotating mechanism is threaded as follows: compressed air enters an annular ventilation groove from the air inlet of the base, enters an axial air channel through the air hole, and then passes from the air inlet of the support table to the air inlet of the clamping cylinder; the air outlet of the rotating mechanism is threaded as follows: the exhaust hole of the clamping cylinder is connected to the air outlet of the support table, and the air outlet of the support table is connected to another axial air channel, which is connected to the air outlet of the base through another annular ventilation groove and the air hole. The design of the rotating mechanism can realize that when the support table and the clamping mechanism turn around and rotate, the gas pipeline does not rotate, so it will not interfere with the processing and disassembly of the workpiece, and the working reliability is high.

[0025] See also Figure 1 , Figure 6 The tightening mechanism is provided with a clamping cylinder 3-1, a clamping cylinder support 3-2 and a baffle plate 3-4. The clamping cylinder support is fixed to the support platform. The clamping cylinder is fixed to one end of the clamping cylinder support through the clamping cylinder mounting plate 3-3. The baffle plate is fixed to the other end of the clamping cylinder support. The baffle plate corresponds to the piston of the clamping cylinder. When the clamping cylinder piston rod is extended, the product is clamped.

[0026] When the present invention is used, the clamping cylinder clamps the product to be processed, the feeding slide moves, and one end of the product is sent to the processing position for corresponding processing; after one end is processed, the rotating mechanism moves, and the rotating mechanism drives the clamping mechanism to rotate 180 degrees, and the other end of the product is processed. After both ends of the product are processed, the feeding slide returns to the initial position. The above process completes the processing of both ends of the product through one loading, reduces one process, and improves work efficiency.
