[0028] The utility model comprises a manipulator mechanism 4 and a workbench. The manipulator mechanism 4 is equipped with a ventilation pipe grabbing mechanism. On the three workbenches are a semi-finished ventilation pipe end cooling tool 2, a semi-finished ventilation pipe end cutting tool 1 and a ventilation pipe punching tool 5. Figure 1 , the manipulator in the manipulator mechanism 4 is an existing manipulator arm, Figure 1 What is shown in the figure is a demonstration diagram of grabbing the ventilation pipe from the semi-finished ventilation pipe end cutting tool 1 to the ventilation pipe punching tool 5. After the mechanical arm is equipped with the ventilation pipe grabbing mechanism, the cooled ventilation pipe rough blank is first grabbed from the semi-finished ventilation pipe end cooling tool 2 to the semi-finished ventilation pipe end cutting tool 1. After the semi-finished ventilation pipe end cutting tool 1 cuts off the excess parts at both ends, it is grabbed to the ventilation pipe punching tool 5. Through this process, only one person is needed to place the blow-molded ventilation pipe rough blank on the semi-finished ventilation pipe end cooling tool 2. Therefore, the overall processing process only requires one person to place the ventilation pipe rough blank and observe whether there are any errors in the working process. The workbench is three work surfaces for placing the semi-finished ventilation pipe end cooling tool 2, the semi-finished ventilation pipe end cutting tool 1 and the ventilation pipe punching tool 5 of the utility model.

[0029] Semi-finished ventilation pipe end cooling tool 2: Four cooling mechanism guide columns 201 are fixed at the four corners of the cooling mechanism workbench 206, and a cooling mechanism top plate 204 is fixedly installed on the top of the cooling mechanism guide column 201. A cooling mechanism lifting plate 203 is installed on the cooling mechanism guide column 201 through a cooling mechanism guide sleeve 202; a cooling mechanism lifting cylinder body 205 is fixed on the cooling mechanism top plate 204, and a cooling mechanism lifting cylinder piston rod 211 passes through the cooling mechanism top plate 204, and the top is fixedly installed with the cooling mechanism lifting plate 203; corresponding ventilation pipe upper cooling mold 210 and ventilation pipe lower cooling mold 207 are respectively installed on the cooling mechanism lifting plate 203 and the cooling mechanism workbench 206, and the ventilation pipe upper cooling mold 210 and the ventilation pipe lower cooling mold 207 are hollow inside and are connected to the cooling water tank through the water inlet and outlet 209; see Figure 2-Figure 4 There are two sets of upper cooling molds 210 and lower cooling molds 207 for the ventilation duct, which correspond to the two ends of the ventilation duct rough blank (semi-finished ventilation duct) respectively. After the two sets of upper cooling molds 210 and lower cooling molds 207 for the ventilation duct are buckled, the ventilation duct rough blank can be closed and clamped in the groove of the mold. Then, cooling circulating water is introduced into the upper cooling mold 210 and the lower cooling mold 207 for the ventilation duct, and the two ends of the ventilation duct rough blank just taken out are cooled and hardened through the upper cooling mold 210 and the lower cooling mold 207 for the ventilation duct (because the ventilation duct rough blank still contains residual heat when it is just taken out of the blow molding machine and is relatively soft, it is very easy to deform if it is directly cut off, thereby affecting the quality of the finished ventilation duct). First, place the two ends of the ventilation duct rough blank correspondingly on the lower cooling mold 207 of the ventilation duct, and then the cooling mechanism lifting cylinder body 205 starts to work, and its piston rod pushes the cooling mechanism lifting plate 203 to move downward until the upper cooling mold 210 of the ventilation duct is completely consistent with the lower cooling mold 207 of the ventilation duct, and the two ends of the ventilation duct rough blank are completely sealed between the upper cooling mold 210 of the ventilation duct and the lower cooling mold 207 of the ventilation duct. After the two ends of the ventilation duct rough blank are cooled and hardened, the piston rod of the cooling mechanism lifting cylinder body 205 moves the cooling mechanism lifting plate 203 upward. After the upper cooling mold 210 of the ventilation duct and the lower cooling mold 207 of the ventilation duct are completely separated, the ventilation duct grasping mechanism on the robot grasps the ventilation duct rough blank after the cooling and hardening at both ends and sends it to the semi-finished ventilation duct two ends cutting tool 1.

[0030] The semi-finished ventilation pipe both ends cutting tool 1: It is divided into an X-end cutting mechanism 101 and a Y-end cutting mechanism 102, and both the X-end cutting mechanism 101 and the Y-end cutting mechanism 102 are installed on a cutting mechanism workbench 103; because the ventilation pipe is at different angles at both ends in order to match the shape of the vehicle body, in order to match the angle cutting accuracy, the X-end cutting mechanism 101 is a vertical cutter, and the Y-end cutting mechanism 102 is an oblique cutter, see details Figure 5 .

[0031] X-end cutting mechanism 101: X-end cutting mechanism bracket 10105 is fixedly installed on the cutting mechanism workbench 103, and a track limiting hole 10114 is opened on the X-end cutting mechanism bracket 10105. The cylinder body of the X-end cutting mechanism cylinder 10101 is fixed on the X-end cutting mechanism bracket 10105. The front end of the piston rod of the X-end cutting mechanism cylinder 10101 is fixedly installed with a sliding connecting rod 10102, and the sliding connecting rod 10102 passes through the track limiting hole 10114 and is connected to the longitudinal cutter bracket 10103. A slide rail sleeve 10113 is installed on the back of the longitudinal cutter bracket 10103. There is a slide rail 10104 on the X-end cutting mechanism bracket 10105, and the slide rail sleeve 10113 is installed to match the slide rail 10104. An X-end cutter 10112 is installed on the cutter bracket 10103; an X-end cutting mechanism stand 10111 is installed on the cutting mechanism workbench 103 close to the X-end cutter 10112, and an X-end cutting mechanism mounting plate 10106 is installed on the top of the X-end cutting mechanism stand 10111 through an X-end cutting mechanism mounting block 10109, the cylinder body of the X-end cutting mechanism lifting cylinder 10107 is fixedly installed on the X-end cutting mechanism mounting plate 10106, and an X-end cutting mechanism movable clamping frame 10108 is installed on the piston rod end of the X-end cutting mechanism lifting cylinder 10107, and an X-end cutting mechanism fixed clamping frame 10110 is installed on the cutting mechanism workbench 103 corresponding to the X-end cutting mechanism movable clamping frame 10108.

[0032] See Figure 6 and Figure 7 , the X-end of the ventilation pipe rough blank is placed on the matching groove of the X-end cutting mechanism fixed clamping frame 10110, and the X-end cutting mechanism lifting cylinder 10107 works, and its piston rod pushes the X-end cutting mechanism movable clamping frame 10108 to move downward, until the groove of the X-end cutting mechanism movable clamping frame 10108 corresponds to the upper side of the X-end of the ventilation pipe rough blank, and the X-end cutting mechanism movable clamping frame 10108 is docked with the X-end cutting mechanism lifting cylinder 10107, and the X-end of the ventilation pipe rough blank is clamped in the groove between the X-end cutting mechanism movable clamping frame 10108 and the X-end cutting mechanism lifting cylinder 10107, and the clamping part is the retained part of the ventilation pipe rough blank X, and the part to be cut extends between the X-end cutting mechanism bracket 10105 and the X-end cutting mechanism clamping frame (the X-end cutting mechanism movable clamping frame 10108 and the X-end cutting mechanism fixed clamping frame 10110);

[0033] Then the X-end cutting mechanism cylinder 10101 works, and the piston rod of the X-end cutting mechanism cylinder 10101 simultaneously moves the sliding connecting rod 10102, the longitudinal cutter bracket 10103, and the X-end cutter 10112 forward along the slide rail 10104 (the X-end cutter 10112 is close to the inner side of the X-end cutting mechanism clamping frame, and the position is just able to cut off the excess part of the X-end of the ventilation pipe rough blank), and the excess part of the X-end of the ventilation pipe rough blank is cut off.

[0034] Y-end cutting mechanism 102: The bottom end of the Y-end cutting mechanism stand 10207 is fixed on the cutting mechanism workbench 103, and the upper end is installed with a Y-end cutting mechanism mounting plate 10208 through a mounting block, the cylinder body of the Y-end cutting mechanism cylinder 10201 is fixedly installed on the Y-end cutting mechanism mounting plate 10208, and the piston rod end of the Y-end cutting mechanism cylinder 10201 is installed with a Y-end cutting mechanism movable clamping frame 10202, and the Y-end cutting mechanism movable clamping frame 10202 is installed on the cutting mechanism workbench 103. The cutting mechanism is fixed with a clamping frame 10203; a Y-end cutting tool holder 10204 is installed on the cutting mechanism workbench 103 on the side of the Y-end cutting mechanism fixed clamping frame 10203, the upper end of the Y-end cutting tool holder 10204 is a Y-end cutting tool guide sleeve 10206, the Y-end cutting knife 10209 is inserted into the Y-end cutting knife guide sleeve 10206, the rear end of the Y-end cutting knife 10209 is connected to the piston rod of the Y-end cutting knife cylinder 10205, and the cylinder body of the Y-end cutting knife cylinder 10205 is fixed on the cutting mechanism workbench 103 through a bracket.

[0035] See Figure 8 and Fig. 9 , the Y end of the ventilation pipe rough blank is placed in the groove on the fixed clamping frame 10203 of the Y end cutting mechanism, and the Y end cutting mechanism cylinder 10201 works, and its piston rod moves downward with the Y end cutting mechanism movable clamping frame 10202 until it cooperates with the Y end cutting mechanism cylinder 10201 to clamp the Y end of the ventilation pipe rough blank, and at the same time, the excess part of the Y end of the ventilation pipe rough blank is located on the upper side of the Y end cutting mechanism clamping frame (the Y end cutting mechanism movable clamping frame 10202 and the Y end cutting mechanism fixed clamping frame 10203); the Y end cutting knife cylinder 10205 works, and its piston rod pushes the Y end cutting knife 10209 to move forward with the Y end cutting knife guide sleeve 10206 as the guide limit until the excess part of the Y end of the ventilation pipe rough blank is cut off.

[0036] Since the X-end and Y-end of the rough ventilation pipe are cooled and hardened in the semi-finished ventilation pipe end cooling tool 2, the two ends of the ventilation pipe after cutting will not be deformed when the X-end cutting mechanism 101 and the Y-end cutting mechanism 102 are cutting.

[0037] Ventilation pipe punching tool 5: the lower end of the punching mechanism column 505 is fixedly installed on the punching mechanism workbench 506, the punching mechanism upper support plate 503 is installed on the top of the punching mechanism column 505, the punching mechanism cylinder 501 cylinder body is fixedly installed on the punching mechanism upper support plate 503, the punching mechanism cylinder 501 piston rod passes through the punching mechanism upper support plate 503, and is installed with a punching mechanism connecting block 511, the punching mechanism guide plate 510 is fixedly installed under the punching mechanism connecting block 511, and a punching knife 504 is installed in the middle of the punching mechanism guide plate 510; the ventilation pipe waist is pressed against the upper die A punching mechanism guide rod 512 is fixedly installed on 508, and the punching mechanism guide rod 512 passes through the guide hole on the punching mechanism guide plate 510, and a guide rod card 513 is installed on the end, and a punching mechanism reset spring 509 is installed on the punching mechanism guide rod 512 between the ventilation duct waist pressing upper mold 508 and the punching mechanism guide plate 510, and a punching knife perforation 514 is opened on the ventilation duct waist pressing upper mold 508 corresponding to the punching knife 504; a ventilation duct waist pressing lower mold 507 is installed on the punching mechanism workbench 506 at the position corresponding to the ventilation duct waist pressing upper mold 508.

[0038] See Fig.10 The punching mechanism upper support plate 503 and two punching mechanism columns 505 form a gantry. The ventilation pipe to be punched is cut from both ends of the semi-finished ventilation pipe by the ventilation pipe grabbing mechanism. The tooling 1 cuts off the excess parts at both ends and is grabbed, and placed in the groove of the ventilation pipe waist pressing lower die 507. The punching mechanism cylinder 501 works, and the piston rod of the punching mechanism cylinder 501 pushes the punching mechanism connecting block 511, the punching mechanism guide plate 510 and the installation mechanism under the punching mechanism guide plate 510 to move downward synchronously until the groove of the ventilation pipe waist pressing upper die 508 is pressed on the ventilation pipe, and cooperates with the ventilation pipe waist pressing lower die 507 to clamp the position. At this time, the ventilation pipe waist pressing die (ventilation pipe waist pressing upper die 508 and ventilation pipe waist pressing lower die 507) clamps and fixes the ventilation pipe shell, and the ventilation pipe that needs to be punched The position of the hole just corresponds to the position of the punching knife perforating hole 514. At this time, the punching mechanism cylinder 501 continues to work, and the waist of the ventilation pipe presses the upper mold 508 and remains stationary, and the punching mechanism guide plate 510 continues to descend with the punching knife 504 (at this time, the punching mechanism reset spring 509 is compressed, and the punching mechanism guide rod 512 extends along the guide hole of the punching mechanism guide plate 510). The punching knife 504 passes through the punching knife perforation 514 until the ventilation pipe N position is punched into the required hole. The punching mechanism cylinder 501 works in the reverse direction to release the clamping of the ventilation pipe. During the gradual ascent, the waist of the ventilation pipe presses the upper mold 508, the punching mechanism reset spring 509, the punching mechanism guide rod 512, etc. are all restored to the initial position ( Fig.10Position). The groove of the lower mold 507 for pressing the waist of the ventilation pipe matches the lower side of the ventilation pipe shell at the hole position N of the ventilation pipe, and the groove of the upper mold 508 for pressing the waist of the ventilation pipe matches the upper side of the ventilation pipe shell at the hole position N of the ventilation pipe. In this way, the lower mold 507 for pressing the waist of the ventilation pipe and the upper mold 508 for pressing the waist of the ventilation pipe can clamp the ventilation pipe.

The two sets of clamping and grasping mechanisms respectively complete the grasping or releasing of the ventilation pipe through the opening and closing of the left clamping jaw 40107 and the right clamping jaw 40106. The opening and closing of the left clamping jaw 40107 and the right clamping jaw 40106 are completed by the extension and retraction of the piston rods on both sides of the two-way cylinder 40103. The so-called two-way cylinder 40103 has piston rods on both sides. The two piston rods move synchronously, and the left clamping jaw 40107 and the right clamping jaw 40106 are extended and retracted to make coordinated movements.
