The machine also includes a first driving component 3, a second driving component 4, a rotating component 5 and a plurality of clamping jaws 2. Each clamping jaw 2 is movably installed in the chassis 1, and each clamping jaw 2 has a clamping valve in the movable stroke relative to the chassis 1. The clamping station of the valve mouth and the rotating station of the flip valve mouth, specifically, the clamping jaw 2 includes a connecting plate 21, a connecting sleeve 23, a ring 24 and two first sliders 22, the connecting plate 21 is fixedly connected to a corresponding rotating rod 32, the two first sliders 22 are both slidably connected to the connecting plate 21, and the two first sliders 22 are both fixedly connected with a clamping plate 221 with an arc groove; the connecting sleeve 23 is movably mounted on the rotating rod 32; the ring 24 is rotatably connected to the connecting sleeve 23, and the two first sliders 22 are hinged to the ring 24 through two hinged rods 222.

[0028] The first driving assembly 3 is used to drive each clamping jaw 2 to switch between the clamping position and the rotating position. Specifically, the first driving assembly 3 includes a first slide plate 31, a second driving member 42 and a plurality of rotating rods 32, which are vertically slidably connected in the chassis 1; the plurality of rotating rods 32 are rotatably connected to the first slide plate 31; the driving member is used to drive the first slide plate 31 to slide relative to the chassis 1; the second driving assembly 4 is used to drive each clamping jaw 2 to clamp and fix the valve nozzle, specifically, the second driving assembly 4 includes a second slide plate 41 and a second driving member 42, the second slide plate 41 is slidably connected to the first slide plate 31, and the second slide plate 41 is connected to each connecting member. The sleeves 23 are all fixedly connected; the second driving member 42 is used to drive the second slide plate 41 to slide relative to the first slide plate 31; the rotating assembly 5 is used to drive each clamping jaw 2 to rotate relative to the chassis 1, specifically, the rotating assembly 5 includes a fixed plate 52, a third driving member 53 and a plurality of gears 51, each gear 51 is coaxially fixedly connected with each rotating rod 32 in a one-to-one correspondence; the fixed plate 52 is fixedly installed in the chassis 1, and a rack 522 is slidably connected to the fixed plate 52 through the second slider 521, and each gear 51 is intermittently meshed with the rack 522; the third driving member 53 is used to drive the rack 522 to slide relative to the fixed plate 52.

[0029] Working principle: the valve is divided into an upper half and a lower half, the lower half of the valve is fixed in a fixed sleeve, and the conveyor belt 11 grinds the valve (sharpening and grinding of the valve are prior art and will not be described in detail here). The upper half of the valve is processed, and during this process, the lower half of the valve and the end of the lower half will be blocked and cannot be ground. After the processing of the upper half is completed, the conveyor belt 11 conveys the valve to the clamping position facing the clamp 2, and then the first driving member 33 drives the first slide plate 31 to slide relative to the frame. The sliding of the first slide plate 31 will move the clamps 2, so that the clamps 2 move to the clamping position. When the clamps 2 move to the clamping position, the second driving member 42 The second slide plate 41 is driven to slide in the direction close to the first slide plate 31. The sliding of the second slide plate 41 drives the connecting sleeve 23 to slide. The sliding of the connecting sleeve 23 drives the collar 24 to move. Then the collar 24 pulls the two first slide blocks 22 closer to each other through the two hinged rods 222. The two first slide blocks 22 approaching each other will clamp the valve stem with the clamping plate 221. When the two clamping plates 221 complete the clamping and fixing of the valve stem, the first driving member 33 drives the first slide plate 31 to slide until each clamping jaw 2 moves to the rotating position and stops sliding. At this time, each gear 51 on the rotating rod 32 is meshed with the rack 522. Then the third driving member 53 drives the second slide block 521 to slide and then drives the rack 522 to slide. The sliding of the rack 522 The movement will cause each gear 51 to rotate (the rack 522 makes a reciprocating linear motion in the process of rotating the gear 51 multiple times, and the rack 522 can rotate the gear 51 clockwise or counterclockwise). The rotation of the gear 51 drives the rotating rod 32 to rotate relative to the first slide 31, and then the rotating rod 32 drives the connecting plate 21 and the valve to rotate. Here, the valve needs to rotate 180 degrees. After the rotation of the valve is completed, the first driving member 33 drives the first slide 31 to slide again, and the first slide 31 drives the clamping jaw 2 to move to the clamping position again. The valve enters the fixed sleeve again, and the positions of the two ends of the valve relative to the fixed sleeve are interchanged. Then the second driving member 42 drives the second slide 41 to move away from the first slide 31. The first driving member 33 drives the first slide plate 31 to slide again so that the clamping jaws 2 do not hinder the horizontal reverse movement of the valve mouth. The lower half of the valve mouth is above the fixed sleeve, and the previously unprocessed position of the valve mouth is exposed. At this time, the valve mouth can be moved by the conveyor belt 11 and moved to the grinder for processing. There are multiple processes for processing the valve mouth in the chassis 1. If the valve mouth needs to be processed, the above method can be repeated. The support legs under the fixed sleeve are convenient for cleaning the debris produced by the valve mouth processing on the conveyor belt 11.

[0030] Compared with the prior art, the present invention provides an automatic valve processing machine. When a grinder completes grinding the upper half of a valve, the valve is moved to the bottom of the clamping station through the conveyor belt 11. The clamping jaw 2 on the clamping station is moved to the clamping station through the first drive assembly 3 to clamp and fix the valve. Then the clamping jaw 2 is moved to the rotating station through the first drive assembly 3 again. The clamping jaw 2 drives the valve to rotate through the rotating assembly 5. Then the first drive assembly 3 drives the clamping jaw 2 to the clamping station again. The valve is inserted into the fixing member 111 again, and the clamping jaw 2 releases the clamping fixation of the valve.

[0031] During this process, the valve mouth is interchanged with the two ends of the fixing part 111, thereby exposing the part of the valve mouth blocked by the fixing part 111. The transmission belt then drives the valve mouth to move the sharpening knife to complete the overall processing of the valve mouth. At this time, the worker does not need to interchange the positions of the two ends of each valve mouth in turn, so that the device can process the valve mouth more comprehensively and efficiently.

[0032] Among them, the first driving member 33 is a hydraulic cylinder, which includes a cylinder barrel and a piston rod. The cylinder barrel is fixedly connected in the chassis 1, and the piston rod is slidably connected to the cylinder barrel. The end of the piston rod away from the cylinder barrel is fixedly connected to the first slide plate 31. The second driving member 42 is an electric push rod, which includes a shell, a driving motor and a push rod. The shell is fixedly installed on the first slide plate 31, and the push rod is slidably connected to the shell. The end of the push rod away from the shell is fixedly connected to the second slide plate 41. The third driving member 53 is a screw stepper motor, and the screw of the screw stepper motor is threadedly connected to the second slider 521. The piston rod of the hydraulic cylinder pushes the first slide plate 31 so that the first slide plate 31 can slide vertically relative to the chassis 1, the push rod of the electric push rod pushes the second slide plate 41 to slide relative to the first slide plate 31, and the screw of the screw stepper motor enables the second slide plate 521 to slide reciprocatingly relative to the fixed plate 52.

[0033] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
