Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, specifically to a valve iron buckle compression port mechanism. Background Technology

[0002] During the assembly of the valve iron, the cylinder needs to be processed by pressing and compressing the opening. Common processing devices include hydraulic ones. However, these devices have drawbacks such as large size and low processing efficiency, and need to be improved. Summary of the Invention

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution: This application discloses a valve iron buckle compression port mechanism, including a servo lifting mechanism, a fixture seat, a slider, and a push block. The servo lifting mechanism has a fixture seat at the top of the housing, and a placement hole for inserting a workpiece is provided in the middle of the top surface of the fixture seat. Slider blocks are elastically and slidably connected at intervals along the circumferential direction on the wall of the placement hole. The end of the lead screw in the servo lifting mechanism extends into the placement hole to support the workpiece at the placement hole. A top cylinder is provided on the nut seat that cooperates with the lead screw, and the top cylinder slides longitudinally with the upper housing cavity wall of the servo lifting mechanism. A push block is provided on the top cylinder, and the end of the push block is inclined to cooperate with the corresponding slider. The nut seat in the servo lifting mechanism moves upward and pushes the slider horizontally. Multiple sliders move the workpiece at the placement hole centripetally.

[0004] In use, when the valve iron is inserted into the mounting hole, the valve iron at the mounting hole is supported by the end of the lead screw in the servo lifting mechanism. The servo lifting mechanism starts to move the top cylinder upward, and simultaneously moves the push block upward. Under the cooperation of the inclined plane, the slider moves horizontally. Multiple sliders move centripetally to clamp the valve iron at the mounting hole. The required configuration can be pre-formed at the end of the slider. At the same time as clamping, the valve iron is deformed by clamping and compressing. Of course, corresponding clamping blocks can also be fixed on the slider to perform the clamping and compressing operation on the valve iron. This device uses a servo lifting mechanism in conjunction with push blocks to perform the clamping and compressing operation on the valve iron, which has higher assembly efficiency and smaller size.

[0005] Furthermore, the slider includes a horizontal part and a vertical part connected to each other. The horizontal part is elastically slidably connected to the wall of the mounting hole in the horizontal direction. The vertical part is located in the mounting hole and forms an inclined surface with the push block, which defines the configuration of the slider and facilitates docking and installation with the fixture seat and forming a cooperation with the push block.

[0006] Furthermore, a first inclined surface is provided on the outward side of the longitudinal part, and a second inclined surface is provided on the inward side of the first end of the push block. The first inclined surface and the second inclined surface are in contact, and the push block moves upward in coordination with the second inclined surface, causing the slider to move horizontally.

[0007] Furthermore, the horizontal part is T-shaped and an elastic element is provided between its horizontal end and the corresponding fixture seat to form an elastic connection. The configuration of the horizontal part is designed to facilitate the formation of an elastic connection and mating structure with the fixture seat.

[0008] Furthermore, in the servo lifting mechanism, a guide hole is provided longitudinally on the upper shell wall, and a guide rod is provided radially on the top cylinder, with the guide rod extending into the guide hole. The top cylinder restricts circumferential rotation through the cooperation between the guide rod and the guide hole, thereby forming a sliding fit with the shell in the longitudinal direction.

[0009] Furthermore, it also includes a support plate, through which the housing of the servo lifting mechanism passes through a hole formed on the support plate and is fixed to the support plate, thereby facilitating docking and fixing with other mechanisms.

[0010] Furthermore, it also includes a clamping block, which is set on the top surface of the slider. When the multiple sliders move inward, the clamping block clamps the workpiece in the middle. The configuration of the clamping block can be designed according to the requirements. When the slider moves inward, the clamping block completes the clamping deformation of the valve iron. The clamping block can be replaced as needed, making it convenient to use.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a servo lifting mechanism for lifting and uses an inclined plane to make the slider move horizontally, which efficiently completes the crimping deformation and shrinking requirements of the valve iron, resulting in a smaller size and easier use.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1 like Figures 1-4 As shown, the valve iron buckle compression mechanism in this example includes a servo lifting mechanism 1, a fixture seat 2, a slider 3, and a pusher 7. The fixture seat 2 is fixed to the top of the housing of the servo lifting mechanism 1. The fixture seat is disc-shaped, and a through hole is formed longitudinally in the center of the top surface of the fixture seat 2, which is the placement hole 21 for inserting the valve iron workpiece. Slide grooves are formed at intervals along the circumferential direction on the wall of the placement hole 21. The slider 3 is elastically slidably connected to the slide grooves. The number of sliders can be selected according to requirements, such as three, six, eight, nine, etc. Figure 2 As shown, in this example, eight sliders 3 are evenly distributed at intervals on the top surface of the fixture seat 2, and the valve iron is pressed at multiple points to better deform the corresponding part of the valve iron to form a constricted configuration.

[0016] For servo lifting mechanisms, such as the common lead screw type, they can be purchased directly from the market, and will not be elaborated further. In this example, the end of the lead screw 13 in the servo lifting mechanism 1 extends into the mounting hole 21. When the valve iron 5 workpiece is placed into the mounting hole 21, the head end of the lead screw 13 supports the valve iron workpiece. This design helps to simplify the structure.

[0017] In the servo lifting mechanism 1, a top cylinder 8 is fixed on the nut seat 12 that mates with the lead screw 13. The top cylinder, or cylindrical structure, is fitted onto and fixed to the nut seat 12. When the nut seat 12 moves longitudinally, the top cylinder 8 moves synchronously. In this example, the top cylinder 8 and the cavity wall of the upper housing 11 in the servo lifting mechanism 1 slide longitudinally. If the peripheral wall of the top cylinder is multi-faceted, such as rectangular or hexagonal, the corresponding cavity wall of the housing matches the peripheral wall of the top cylinder to fit snugly, thereby restricting the circumferential rotation of the top cylinder. Of course, it is preferable to use... Figure 4 As shown in the configuration, a guide rod 10 is radially fixed at the periphery of the top cylinder 8. A guide hole is formed longitudinally at the corresponding cavity wall of the shell, with the guide rod extending into the guide hole to restrict the circumferential rotation of the top cylinder. When the lead screw rotates, the top cylinder moves longitudinally. The top cylinder can be integrally formed or assembled from two separate parts, either vertically or horizontally, depending on the requirements.

[0018] At the top surface of the first end of the top cylinder 8, push blocks 7 are evenly fixed circumferentially. Each push block 7 corresponds one-to-one with a slider, and the end of the push block 7 engages with the corresponding slider via an inclined surface. Specifically, the slider 3 includes a connected horizontal portion 32 and a longitudinal portion 33. The horizontal portion is the part extending horizontally, and the longitudinal portion is the part extending longitudinally. Figure 3 As shown, the longitudinal part 33 is located at the bottom surface of the horizontal part 32, and the two can be integrally formed or assembled separately.

[0019] The horizontal part 32 and the wall of the mounting hole 21 are elastically slidably connected horizontally upwards, such as... Figure 2 As shown, the horizontal part 32 is T-shaped and an elastic element 9 is placed between its horizontal end and the corresponding fixture seat 2 to form an elastic connection. Commonly, a spring is used as the elastic element to cause the slider to return to its original position.

[0020] The longitudinal part 33 is located in the mounting hole 21 and forms an inclined surface with the push block 7. For example, an inclined surface 31 is formed on the outward side of the longitudinal part 33, and an inclined surface 2 is formed on the inward side of the first end of the push block 7. The inclined surface 1 and the inclined surface 2 are in contact. When in use, if the push block moves upward, with the cooperation of the inclined surface 1 and the inclined surface 2, the upward-moving push block pushes the slider to move horizontally, and then the multiple sliders move centripetally to clamp the valve iron in the middle.

[0021] In use, the end configuration of the slider can be directly designed, and the slider directly forms a clamping action when moving centripetally. Preferably, as follows... Figure 1 , Figure 4 As shown, a clamping block is added. The clamping block is fixed to the top surface of the slider by bolts, etc. The configuration of the clamping block can be pre-formed according to different processing requirements. When the multiple sliders move in the center, the clamping block clamps the valve iron workpiece in the middle. The clamping block can be replaced at any time, which is convenient for operation.

[0022] To facilitate the docking and fixing of this mechanism with other mechanisms, a support plate can be added. In the servo lifting mechanism 1, the housing 11 passes through the hole formed on the support plate 6 and the housing 11 is fixed to the support plate 6. During installation, the support plate can be fixed to other external mechanisms.

[0023] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
