Description

Technical Field

[0001] The utility model relates to the technical field of valve body assembly production equipment, and more specifically, to a valve body installation and sorting device. Background Art

[0002] The valve stem is an important component of the valve and is used for transmission. It is connected to the actuator or handle at the upper end and directly drives the valve core to move or rotate at the lower end to achieve the opening, closing or regulating function of the valve. During the opening and closing process of the valve, the valve stem is not only a moving part and a stressed part, but also a sealing part. At the same time, it is subjected to the impact and corrosion of the medium and friction with the packing. Therefore, when selecting the valve stem material, it is necessary to ensure that it has sufficient strength, good impact toughness, anti-galling property and corrosion resistance at the specified temperature. The valve stem is a vulnerable part, and attention should also be paid to the machining performance and heat treatment performance of the material when selecting it.

[0003] At present, the conveying equipment used for valve stem production has a relatively simple structure. The valve stem will move or be placed horizontally during the conveying process, affecting the processing effect. In addition, the current conveying equipment is difficult to adapt to the conveying and transmission of valve stems of different specifications and sizes. Moreover, the processing assistance effect for the valve stem is also insufficient. In the existing patent, a conveying device for valve stem production, in the patent with the authorization number CN213975669U, a movable plate is installed at the upper end of the side baffle, and a shunt rod is connected to the side surface of the movable plate to sort the valve stem during the conveying process, prevent the valve stem from being placed horizontally, and facilitate further processing.

[0004] However, in the patent with the authorization number CN213975669U, the valve stem is horizontally conveyed during the processing using conveying rollers. The valve stem is first introduced by the feeding plate and forms a horizontal feeding transmission using the conveying rollers. During this process, a movable plate is installed at the upper end of the side baffle, and a shunt rod is connected to the side surface of the movable plate to sort the valve stem during the conveying process and prevent the valve stem from being placed horizontally. Although the valve stem can be sorted, it is impossible to convey the valve stem one by one in an orderly manner and cannot meet the requirements of the existing pipeline combination installation. Therefore, we propose a valve body installation and sorting device to solve the above existing problems. Content of the Utility Model

[0005] 1. Technical Problems to be Solved

[0006] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a valve body installation and sorting device. It can drive the connecting rod to make a circular motion through the operation of the servo motor. While the connecting shaft rotates in cooperation with the connecting rod, the eccentric shaft rod makes an eccentric motion in cooperation with the turntable seat, so that the connecting frame drives the supporting seat to lift the valve stem workpiece, and then places the valve stem workpiece between the corresponding positioning convex teeth, and cycles in this way. It can sort the valve stem workpieces one by one and convey them in an orderly manner, and can meet the requirements of the existing pipeline valve body combination installation.

[0007] 2. Technical Solution

Positioning convex teeth are integrally formed at the tops of both the first support plate and the second support plate, and a plurality of the positioning convex teeth are arranged at equal intervals;

[0010] A connecting frame is installed between the first support plate and the second support plate. A support seat is fixedly connected to the top end of the connecting frame, and a plurality of the support seats are arranged at equal intervals. A connecting shaft is installed in the middle of the surface of the connecting frame close to the first support plate;

[0011] A servo motor is installed on the outer facade of the first support plate. The power output end of the servo motor penetrates the first support plate, and a connecting rod rotatably connected to the connecting shaft is installed at the power output end of the servo motor;

[0012] A turntable is rotatably connected to the inner facade of the second support plate. An eccentric shaft rod is installed at the edge part of the turntable, and the end of the eccentric shaft rod is rotatably connected to the end part of the connecting frame.

[0013] Further, a positioning groove is arranged between two adjacent positioning convex teeth, and the positioning groove is engaged with the valve stem workpiece.

[0014] Further, an arc-shaped groove is formed at the top of the support seat corresponding to the axial position of the valve stem workpiece.

[0019] 3. Beneficial Effects

[0020] Compared with the prior art, the advantages of the utility model are as follows:

[0021] (1) In this solution, the valve rod workpiece is limited by the positioning convex teeth at the end parts of the first support plate and the second support plate. The servo motor drives the connecting rod to perform circular motion. While the connecting shaft rotates in cooperation with the connecting rod, the eccentric shaft rod moves eccentrically in cooperation with the turntable seat, causing the connecting frame to drive the support seat to lift the valve rod workpiece. Then, the valve rod workpiece is placed between the corresponding positioning convex teeth and circulated in this way, so that the valve rod workpieces can be sorted one by one and conveyed orderly, meeting the requirements of the existing assembly line valve body combination installation.

[0022] (2) In this solution, the rib plate is used to improve the structural strength of the joint between the first support plate and the second support plate and the support frame, which can improve the bearing capacity of the support frame. After the valve rod workpiece is limited by the positioning convex teeth at the end parts of the first support plate and the second support plate, the movable end of the double-acting cylinder extends, making the rubber head abut against the end of the valve rod workpiece, aligning the valve rod workpiece in the middle, which is beneficial to the subsequent assembly between the valve rod workpiece and the valve body.

[0035] It should be noted that when the valve body installation and sorting device is in use, first, the valve stem workpiece 1 is successively guided to the end parts of the first support plate 2 and the second support plate 3, and the valve stem workpiece 1 is limited by the positioning convex teeth 4 at the end parts of the first support plate 2 and the second support plate 3. By the operation of the servo motor 7 to drive the connecting rod 8 to make a circular motion, while the connecting shaft 17 cooperates with the rotation of the connecting rod 8, the eccentric shaft rod 10 makes an eccentric motion in cooperation with the turntable 9, so that the connecting frame 5 drives the support seat 6 to lift the valve stem workpiece 1, and then the valve stem workpiece 1 is placed between the corresponding positioning convex teeth 4, and this cycle is repeated, so that the valve stem workpiece 1 can be sorted one by one and conveyed orderly, which can meet the requirements of the existing pipeline valve body combined installation.

[0036] As Figure 1 shown, a positioning groove is arranged between two adjacent positioning convex teeth 4, and the positioning groove is engaged with the valve stem workpiece 1;

[0037] It should be noted that by using the positioning groove between the positioning convex teeth 4 to limit the valve stem workpiece 1, it is beneficial to convey the valve stem workpiece 1 orderly.
