[0048] The conveyor belt 1 7 and the conveyor belt 2 8 are both extended to the lower side of the middle turntable 4. The outer side of the middle turntable 4 is provided with three groups of square openings 403.

[0049] The visual inspection mechanism 5 includes an image acquisition component 501 and a driving wheel 502.

[0051] The valve cover body 6 is transported to the end of the conveyor belt 1 7 by the conveyor belt 1 7, and the conveyor belt 1 7 and the conveyor belt 2 8 are extended to the lower side of the middle turntable 4, and the middle turntable 4 rotates the square opening 403 to dock with the conveyor belt 1 7, so that the valve cover body 6 is directly transported to the square opening 403; then the feeding part 1 drives the clamping claw assembly to descend to clamp the valve cover body 6 and bring it up, and then the middle turntable 4 rotates the limiting hole 401 to the lower side of the valve cover body 6, and the clamping claw assembly releases the valve cover body 6 to make it fall into the limiting hole 401, and a pair of baffles 402 merge with each other to support the valve cover body 6; then the middle turntable 4 drives the valve cover body 6 to move to the lower side of the image extraction component 501, and since the driving wheel 502 extends to the annular groove outside the middle turntable 4, and the annular groove is communicated with the limiting hole 401, the valve cover body 6 part in the limiting hole 401 extends into the annular groove, so that the driving wheel 502 and the valve The valve cover body 6 contacts, specifically, the hole position of the valve cover body 6 is detected by the image extraction component 501, and then the driving wheel 502 drives the valve cover body 6 to rotate through friction, and adjusts the hole position to the corresponding position of tapping; then the turntable 4 drives the valve cover body 6 to move to the lower side of a plurality of taps 201, and the plurality of taps 201 perform tapping processing on the through holes of the valve cover body 6; then the turntable 4 drives the valve cover body 6 to move to the upper side of the conveyor belt 2 8, and a pair of baffles 402 unfold each other, so that the valve cover body 6 falls onto the conveyor belt 2 8, and the automatic tapping production of the valve cover body 6 can be completed. Three groups of workstations are provided, so that the loading, hole position adjustment, tapping and unloading processes are carried out simultaneously, which greatly improves the processing efficiency, and the clamping jaw assembly only needs to move up and down to realize the automatic loading of the valve cover body 6, and no additional driving components and control programs are required for horizontal displacement drive, saving costs.

[0052] The clamping jaw assembly includes a pair of concave wheels 101, the wheel surface of the concave wheels 101 is adapted to the upper end portion of the valve cover body 6, the center of the concave wheels 101 is fixedly connected to a rotating rod, and the two ends of the rotating rod are rotatably connected to a pair of moving plates 102, a pair of fixed plates 103 are arranged on both sides of the pair of concave wheels 101, and a plurality of guide rods 104 are fixedly connected between the pair of fixed plates 103, and the guide rods 104 penetrate the moving plate 102 and slide with it, and a spring member is arranged between the fixed plate 103 and the moving plate 102;

[0053] An annular groove 105 is provided on one side of the concave wheel 101, and an arc-shaped clamping piece 106 is arranged in the annular groove 105. The annular groove 105 is adapted to the arc-shaped clamping piece 106. A spring telescopic rod 1 is arranged between the arc-shaped clamping piece 106 and the movable plate 102. The arc-shaped clamping piece 106 limits the one-way rotation of the concave wheel 101.

[0054] Preferably, a spring member is provided to drive the pair of concave wheels 101 to generate a force offset toward the center. When the valve cover body 6 needs to be clamped, the pair of fixing plates 103 are driven to descend, thereby driving the pair of concave wheels 101 to descend. The surface of the concave wheels 101 is arranged to be compatible with the upper end portion of the valve cover body 6, so that the pair of concave wheels 101 are clamped on the upper end portion of the valve cover body 6 and roll downward along it, and are mutually clamped by the annular clamping groove 105 and the arc clamping member 106, so that the concave wheels 101 can only rotate in one direction, that is, when the concave wheels 101 descend, they can be clamped and fitted on the upper end of the valve cover body 6 and roll downward, and when the concave wheels 101 rise, they cannot roll upward. At this time, the concave wheels 101 cannot rotate, and the concave wheels 101 can rotate by the annular clamping groove 105 and the arc clamping member 106. The clamping of the valve cover body 6 drives the valve cover body 6 to rise synchronously, so that it can be grabbed and lifted for loading. Specifically, the annular groove 105 is adapted to the arc clamp 106, and the two can be stuck in one direction. When the annular groove 105 rotates along the arc surface of the arc clamp 106, the arc clamp 106 is pushed along the arc surface by the annular groove 105, so that it is continuously moved out of the groove, and the two can rotate relative to each other. On the contrary, when the annular groove 105 rotates against the arc surface of the arc clamp 106, the arc clamp 106 is stuck in the annular groove 105, and the two cannot rotate relative to each other, so that the concave wheel 101 can roll downward, but cannot rotate upward, thereby driving the valve cover body 6 to rise synchronously;

[0055] When the clamped valve cover body 6 needs to be released, a pair of movable plates 102 are spread apart to drive a pair of concave wheels 101 to separate from each other, so that the valve cover body 6 loses its restriction and descends into the limiting hole 401 under the action of gravity to complete the unloading.

[0056] The upper end of the fixed plate 103 is fixedly connected to a support plate 107, and guide columns 108 are opened on four sides of the support plate 107. The upper end of the guide column 108 is fixedly connected to a top plate 109, and a cylinder 110 is provided at the upper end of the top plate 109. The cylinder 110 is used to drive the support plate 107 to rise and fall.

[0057] Preferably, the support plate 107 is driven to rise and fall by the cylinder 110, thereby driving a pair of fixed plates 103 and the concave wheel 101 to rise and fall, so that the loading work can be realized, and a plurality of guide columns 108 are provided for guidance.

[0058] A plurality of spring telescopic rods 111 are provided at the lower sides of both ends of the support plate 107, and an extension bar 112 is provided at the lower end of the spring telescopic rod 111. The upper end of the extension bar 112 is fixedly connected to a limit block 113, and inclined surfaces are provided on both sides of the upper end of the limit block 113. A rotating column 114 is rotatably connected to the outer side of the movable plate 102, and the rotating column 114 corresponds to the inclined surface. The upper end surface of the extension bar 112 is flush with the lower end surface of the fixed plate 103.

[0059] A magnet block is arranged inside the fixed plate 103, and the movable plate 102 is arranged to be a magnetic metal;

[0060] The lower end of the guide column 108 is provided with an inclined surface, which corresponds to the rotating column 114 .

[0061] Preferably, a spring telescopic rod 111 is provided so that the extension bar 112 is located at the lower end of the fixed plate 103 (eg Figure 6 As shown in the figure), when it is necessary to clamp the valve cover body 6 on the conveyor belt 7, the support plate 107 descends, so that the pair of concave wheels 101 clamp the upper end of the valve cover body 6, and at this time, the lower end surface of the fixing plate 103 and the disc of the valve cover body 6 maintain a distance of an extension bar 112, that is, the state of the spring telescopic rod 2 111 at this time is in an uncompressed state, and then the valve cover body 6 can be raised, and then the turntable 4 rotates, so that the limiting hole 401 moves to the lower side of the valve cover body 6, and then when the valve cover body 6 needs to be released, the support plate 107 descends, and the valve cover body 6 is placed in the limiting hole 401. At this time, the valve cover body 6 cannot continue to descend, and the support plate 107 continues to descend, so that the pair of extension bars 112 first contact with the valve cover body 6 and remain motionless. At this time, the spring telescopic rod 2 111 is compressed, and the fixing plate 103 is relatively extended relative to the bar 112. When the support plate 107 is lifted up and the support plate 107 is lifted up, the support plate 107 is lifted up and ...

[0062] The tapping assembly 2 also includes a support frame 202, a plurality of guide telescopic rods 203 are arranged at the lower end of the support frame 202, a lifting seat 204 is arranged at the lower end of the guide telescopic rods 203, a lifting plate 205 is fixedly connected to one side of the lifting seat 204, the lifting plate 205 is slidably matched with the vertical rod of the support frame 202, a motor part is fixedly connected to the upper end of the support frame 202, a threaded rod 206 is driven at the lower end of the motor part, the threaded rod 206 passes through the lifting plate 205 and is threadedly connected thereto, a chuck part is arranged at the upper end of the tap 201, and the upper end of the chuck part is rotatably connected to the lifting seat 204.

[0063] Preferably, the threaded rod 206 is driven to rotate by a motor, driving the lifting plate 205 to lift and lower under the guidance of a number of guide telescopic rods 203, and the lifting plate 205 drives the lifting seat 204 to move, thereby driving a number of chuck members and taps 201 to move, and tapping is performed on a number of through holes of the valve cover body 6 simultaneously. Since a number of taps 201 are tapped simultaneously, no additional clamping assembly is required to clamp the valve cover body 6, and the stability of the valve cover body 6 during tapping can be maintained, saving manufacturing costs.

[0064] The upper end of the chuck is fixedly connected with gear 1 207, the outer side of gear 1 207 is meshedly connected with an inner gear ring 208, the upper end of the inner gear ring 208 is fixedly connected with a gear ring 209, the inner side of the gear ring 209 is rotatably connected to the lifting seat 204, one side of the gear ring 209 is meshedly connected with gear 2 210, and the inner side of gear 210 is provided with a driving shaft 211.

[0065] Preferably, when it is necessary to drive several taps 201 to rotate synchronously, the drive shaft 211 drives the gear 2 210 to rotate, and the gear ring 209 and the inner gear ring 208 are driven to rotate through the meshing connection. The inner gear ring 208 is meshed with several gears 1 207 at the same time, thereby driving the several taps 201 to rotate.

[0067] Preferably, since the tap 201 needs to rotate at a constant speed and also descend at a constant speed during tapping, when tapping is completed, the tap 201 needs to rotate in the opposite direction and ascend in order to reverse and ascend and reset along the tapped thread. Therefore, the gear 210 needs to move synchronously with the lifting plate 205 so that the gear 210 and the gear ring 209 can always be kept meshed with each other. Therefore, a rotating ring 214 is provided, and the rotating ring 214 connects the lifting plate 205 and the gear 210, so that the lifting plate 205 synchronously drives the gear 210 to move with the gear ring 209 to maintain normal meshing connection, and a keyway is provided on the inner side of the drive shaft 211, and the gear 210 transmits torque to it through a straight key, so that the gear 210 can slide along the drive shaft 211 without affecting the rotation of the gear 210 driven by the drive shaft 211, thereby realizing the rotation and descent of the tap 201 for tapping;

[0068] Preferably, a belt transmission mechanism is provided so that when the threaded rod 206 rotates, the drive shaft 211 is synchronously driven to rotate, so that the threaded rod 206 drives the tap 201 to descend while also driving it to rotate, so that the rotation speed of the tap 201 is the same as that of the threaded rod 206, and the tap 201 is further guaranteed to descend at a uniform speed, and the two have good synchronization. After the tapping is completed, the threaded rod 206 is reversed, so that the tap 201 can be raised and reset, and rotate in the opposite direction, which is highly practical and does not require additional drive components or control programs to control and drive the tap 201. Only the threaded rod 206 needs to be driven to rotate to achieve the tapping and resetting of the tap 201, thereby saving costs.

[0069] A plurality of adapting cavities 404 are provided inside the turntable 4, and the baffles 402 move in the adapting cavities 404. A connecting rod 405 is fixedly connected to one side of a pair of baffles 402, and a hinge plate 406 is fixedly connected to one side of the connecting rod 405. The two hinge plates 406 are staggered up and down, and the center of the hinge plate 406 is rotatably connected to a hinge rod 407.

[0070] Preferably, two hinge plates 406 are staggered up and down and hingedly connected to the hinge rod 407 at the same time, so that a pair of connecting rods 405 and hinge plates 406 rotate relative to each other with the hinge rod 407 as the center, thereby driving a pair of baffles 402 to move relative to each other. When the pair of baffles 402 are combined, the baffles 402 extend to the inner side of the limiting hole 401 to support and limit the valve cover body 6. When the pair of baffles 402 are unfolded, the baffles 402 retract into the adaptation cavity 404, release the support and limit of the valve cover body 6, so that it falls from the limiting hole 401 to the conveyor belt 2 8 to complete the unloading.

[0071] It should be noted that the adaptable cavity 404 is only shown as a schematic diagram in the drawings of the specification, and its shape is not fixed as long as it does not hinder the movement of the baffle 402.

[0072] A torsion spring is arranged between the hinge plate 406 and the hinge rod 407, and the middle side of the turntable 4 is penetrated by and rotatably connected with the center column 301, and the turntable 4 rotates relative to the center column 301, and an annular groove 302 is opened on the inner side of the upper end of the turntable 4, and a slide groove 3 is opened on the inner side of the upper end of the turntable 4, and the slide groove 3 extends to the annular groove 302, and the lower end of the slide groove 3 is communicated with the adaptation cavity 404, and a trapezoidal wedge block 304 is slidably matched in the slide groove 3, and a spring telescopic rod three 305 is arranged between the trapezoidal wedge block 304 and the slide groove 3, and the hinge rod 407 is fixedly connected to the trapezoidal wedge block 304, and a protrusion 303 is fixedly connected to the end of the upper end of the center column 301 close to the conveyor belt two 8, and the protrusion 303 corresponds to the inclined surface of the trapezoidal wedge block 304, and a pair of baffle rods 306 are fixedly connected in the adaptation cavity 404, and the baffle rod 306 is in contact with the connecting rod 405.

[0073] Preferably, when it is necessary to drive a pair of connecting rods 405 to rotate relative to each other, a trapezoidal wedge block 304 is provided. Specifically, when the trapezoidal wedge block 304 moves along the slide groove 3, the hinge rod 407 is driven to move, and the hinge rod 407 drives the two hinge plates 406 to move linearly and horizontally, and the connecting rod 405 contacts and is limited by the stop rod 306, thereby driving a pair of baffles 402 to expand to both sides, and the limit on the valve cover body 6 can be released;

[0074] Preferably, an annular groove 302 is provided on the inner side of the middle rotating disk 4, which is connected to the slide groove 3, so that the trapezoidal wedge block 304 extends into the annular groove 302 in the initial state (such as Fig.11 As shown in the figure), when the middle turntable 4 rotates relative to the center column 301, the middle turntable 4 drives the processed valve cover body 6 to move toward the conveyor belt 2 8. A protrusion 303 is provided in the direction of the conveyor belt 2 8. When the inclined surface of the trapezoidal wedge block 304 contacts the protrusion 303, the protrusion 303 limits the movement of the trapezoidal wedge block 304. The trapezoidal wedge block 304 can drive a pair of baffles 402 to unfold, so that the valve cover body 6 falls onto the conveyor belt 2 8, completing automatic unloading. After the unloading is completed, the baffle 402 is reset by the torsion spring member to prepare for subsequent processing. The degree of automation is high, and no additional drive component is required. The unloading can be realized synchronously by rotating the middle turntable 4 to drive the valve cover body 6 to move, which is highly practical.
