Description

Technical Field

[0001] The utility model relates to the technical field of valve seat processing, in particular to an automatic feeding device for valve seat processing. Background Art

[0002] The valve seat is a component in the valve that directly contacts the fluid and controls the fluid flow. Its processing quality directly affects the sealing performance, durability, and overall performance of the valve. Therefore, valve seat processing occupies an important position in valve manufacturing and maintenance.

[0003] During the valve seat processing, a stepped feeding machine is used. Through the stepped feeding machine, the valve seat is then righted so that the valve seat is placed in an inverted T shape for transmission, and subsequent processing operations are carried out accordingly.

[0004] However, during valve seat processing and production, valve seats of different models and sizes are produced. The traditional stepped feeding machine generally installs an L-shaped clamping plate, and the L-shaped clamping plate is installed and positioned by bolts. When the model of the valve seat changes, the bolts are then rotated to release the limit of the bolts, and then the L-shaped clamping plate is adjusted. The bolts have been over-tightened, and greater force is required to overcome the established tightening force when rotating again. The overall operation is rather troublesome and time-consuming. Moreover, when the valve seat is not placed in an inverted T shape, the L-shaped clamping plate will squeeze the valve seat and drop it into the collection box. When there are fewer valve seats, the valve seat may be damaged when it drops. For this reason, an automatic feeding device for valve seat processing is proposed to solve the above problems. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides an automatic feeding device for valve seat processing, aiming to improve the problem that the operation of rotating bolts to release the L-shaped clamping plate is relatively troublesome in the prior art.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figures 1 - 3, an embodiment provided by the present utility model: an automatic feeding device for valve seat processing, including a base 1. A collection box 2 is fixedly connected to the top end of the base 1. The collection box 2 is used to collect valve seats that are not placed in an inverted T shape for subsequent repositioning operations. A conveying plate 3 is arranged at the top end of the base 1. The conveying plate 3 is driven by a motor to achieve the purpose of transmission. At the same time, correctly placed valve seats can move to the left end, and incorrectly placed valve seats will fall onto the inner wall of the collection box 2 for repositioning. A baffle 4 is fixedly connected to the rear end of the base 1. A disassembly mechanism 5 is arranged on the inner wall of the baffle 4. The disassembly mechanism 5 can achieve the purpose of quick disassembly and adjustment. The disassembly mechanism 5 includes a movable plate 501. The outer wall of the movable plate 501 is slidably connected to the inner wall of the baffle 4, and the two slide to achieve the adjustment purpose. A support block 502 is fixedly connected to the top end of the movable plate 501. The movable plate 501 can play a supporting role for the support block 502. An insertion plate 508 is elastically connected to the inner wall of the support block 502 through a connecting spring 507. The insertion plate 508 passes through and is slidably connected to the inside of the support block 502. The through setting facilitates the movement of the staff. A threaded rod 506 is threadedly connected to the inner wall of the movable plate 501. The setting of the threaded rod 506 can achieve the purpose of precise adjustment. The bottom end of the threaded rod 506 is rotatably connected to a bottom plate 503. The bottom plate 503 plays a connecting role. A guiding column 505 is fixedly connected to the inner wall of the movable plate 501. The guiding column 505 can play a guiding role. A clamping plate 504 is fixedly connected to the front end of the bottom plate 503. The setting of the clamping plate 504 can make the placement position of the valve seat correct. A buffer mechanism 6 is arranged on the inner wall of the collection box 2. The buffer mechanism 6 can play a buffering role for the falling valve seat, reducing the occurrence of damage due to falling.

[0031] Refer to Figures 1 - 3 , one end of the connecting spring 507 is fixedly connected to the outer wall of the insertion plate 508, and the other end of the connecting spring 507 is fixedly connected to the inner wall of the support block 502. The insertion plate 508 is slidably connected to the inner wall of the support block 502. Through the elasticity of the connecting spring 507, the insertion plate 508 has a reset and limiting function. A plurality of insertion holes are opened on the inner wall of the baffle 4. The outer wall of the insertion plate 508 is inserted into the inner wall of the baffle 4. The setting of the plurality of insertion holes facilitates the movement and adjustment of the position of the clamping plate 504. The inner wall of the bottom plate 503 is slidably connected to the outer wall of the guiding column 505. The guiding column 505 can play a guiding role for the bottom plate 503, making it only able to move vertically. Two insertion plates 508 are provided, and both of the two insertion plates 508 are L-shaped. The L-shaped setting facilitates insertion and fixation, and they are arranged staggeredly. The staggered setting can achieve the purpose of saving space.

[0032] Refer to Figure 1 and Figure 4, the buffer mechanism 6 includes a volute spring 602. One end of the volute spring 602 is fixedly connected to the inner wall of the collection box 2, and the other end of the volute spring 602 is fixedly connected to a rotating rod 603. The elastic force of the volute spring 602 enables the rotating rod 603 to have a reset buffering function. A buffer plate 601 is fixedly connected to the front end of the rotating rod 603. A corresponding rubber pad can be provided at the top of the buffer plate 601. A moving seat 7 is slidably connected to the inner wall of the collection box 2. An electric telescopic rod is provided at the bottom of the moving seat 7. The moving seat 7 is driven to move vertically by the electric telescopic rod. This is the prior art and will not be explained in detail here. The outer wall of the rotating rod 603 is rotatably connected to the inner wall of the collection box 2, and the rotation of the two avoids movement interference.

[0033] Working principle: When feeding the valve seat, place multiple groups of valve seats inside the collection box 2, and then start the cylinder at the bottom of the moving seat 7. Then the moving seat 7 moves upward to push the valve seats inside the collection box 2 onto the conveying plate 3. If the valve seat is in an inverted T shape, it can pass through and move to the left end. If it is in a regular T shape, it will fall inside the collection box 2 when it touches the clamping plate 504. And when the valve falls, it will touch the buffer plate 601, causing the buffer plate 601 to rotate. When the buffer plate 601 rotates, it will touch and compress the volute spring 602. Through the elasticity of the volute spring 602, part of the impact force when the valve falls can be reduced, thereby reducing the situation of valve damage due to gravity. When the model of the valve changes, at this time, pinch the two plug-in plates 508 to release the plug-in connection between the two plug-in plates 508 and the inner wall of the baffle 4, and then the movable plate 501 can be moved upward to adapt to valves of different lengths. And the bottom plate 503 can also be driven to move downward by rotating the threaded rod 506, and then the clamping plate 504 moves downward, so as to perform precise adjustment.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
