Description

Technical Field

[0001] The utility model relates to the technical field of piston processing devices, in particular to a crank slider support mechanism. Background Art

[0002] The piston is a reciprocating part in the cylinder block of a car engine. During the manufacturing process of the piston, the bottom of the piston is placed on the top of the tray, and then the tray is lifted and lowered by an auxiliary support mechanism to facilitate the processing of the piston.

[0003] The utility model patent with patent application publication number CN 220372734 U discloses a crank slider support mechanism, which has better stability without shaking and is convenient for piston processing. It includes a base, the upper end of the base is connected to a positioning plate through a pillar, the bottom of the tray is inserted into the positioning plate and movably connected, and a supporting plate that cooperates with each other is provided at the bottom position of the base corresponding to the bottom of the tray. The supporting plate is movably connected through a guide rod fixedly connected to the base, and the upper end of the base and the lower end of the supporting plate are respectively provided with a relative upper positioning block and a lower positioning block, and a wedge-shaped sliding block that slides and cooperates is provided between the upper positioning block and the lower positioning block. A hydraulic cylinder is provided on the side of the base, and the piston rod of the hydraulic cylinder is connected to the side of the sliding block through a connecting rod mechanism. The sliding block is pushed by the hydraulic cylinder to be inserted between the upper positioning block and the lower positioning block, and the supporting plate is driven to move up.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when manufacturing the piston, a crank slider support mechanism is required to drive the pallet to move up and down to perform production operations. However, the device can only drive the pallet to move upward. When the sliding wedge slides out, the pallet and the upper positioning block can only be driven downward by the pallet's own gravity. During the descent process, the friction between the support plate and the guide rod will cause the pallet to not descend in time or shake, resulting in quality problems in the piston processing, affecting the quality of the piston and reducing production efficiency.

[0005] Therefore, it is necessary to invent a crank slider support mechanism to solve the above problems. Utility Model Content

[0027] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged in addition without departing from the technical concept of the present disclosure.

[0030] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.

[0031] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0032] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would subsequently be positioned "over" the other components or features. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0033] The terms used here are for the purpose of describing specific embodiments, and are not intended to be restrictive. As used here, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, parts, assemblies and / or their groups, but it is not excluded that there are or add one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups. It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or the values ​​provided that will be recognized by those of ordinary skill in the art.

[0037] Figure 3 1 is a side view of the overall structure of a crank slider support mechanism according to an embodiment of the present disclosure.

[0038] like Figure 2-3As shown, the operating table assembly 1 described in the present disclosure includes an operating table body 11, a support rod 12, a top plate 13, a mounting seat 14, a tray 15, a side plate 16 and a limit plate 17, wherein the support rod 12 is fixedly connected to the top of the operating table body 11, the top plate 13 is fixedly connected to the top of the support rod 12, the mounting seat 14 is fixedly connected to the top of the support plate 23, the tray 15 is fixedly installed above the mounting base, the side plate 16 is fixedly connected to the outside of the operating table body 11, and the limit plate 17 is fixedly connected to the top of the operating table body 11.

[0039] Figure 4 It is a schematic diagram of the crank mechanism structure of a crank slider support mechanism according to an embodiment of the present disclosure.

[0040] like Figure 3-4 As shown, in a preferred embodiment, the crank mechanism 3 includes a first rotating rod 31, a connecting plate 32, a second rotating rod 33, a supporting wedge 34, a sliding groove 35, a rotating plate 36, a hydraulic cylinder 37 and a mounting plate 38, wherein one end of the first rotating rod 31 is rotatably connected to the side plate 16 by a pin and is located above the side plate 16, the connecting plate 32 is rotatably connected to the other end of the first rotating rod 31 by a pin and is located above the first rotating rod 31, one end of the second rotating rod 33 is rotatably connected to the connecting plate 32 by a pin and is located below the connecting plate 32, the supporting wedge 34 is rotatably connected to the second rotating rod 33 by a pin and is located on the outside of the second rotating rod 33, the sliding groove 35 is opened on the lower surface of the first rotating rod 31, the rotating rod is rotatably connected to the first rotating rod 31 by a pin and is located inside the sliding groove 35, the hydraulic cylinder 37 is fixedly connected below the rotating plate 36, and the mounting plate 38 is fixedly connected below the hydraulic cylinder 37 and is fixedly connected to the operating table body 11.

[0041] Therefore, the operator first opens the hydraulic cylinder 37, and the hydraulic cylinder 37 contracts downward to drive the rotating plate 36 to slide in the sliding groove 35. While the rotating plate 36 slides, it drives the first rotating rod 31 to rotate downward. The first rotating rod 31 rotates downward to drive the second rotating rod 33 to rotate downward. The second rotating rod 33 rotates downward to drive the supporting wedge block 34 to slide forward under the limit of the limit plate 17. Similarly, the hydraulic cylinder 37 is extended and retracted upward to drive the supporting wedge block 34 to slide backward.

[0042] Figure 5 It is a schematic diagram of a positioning block assembly of a crank slider support mechanism according to an embodiment of the present disclosure.

[0043] Figure 6 is a side view of a positioning block assembly of a crank slider support mechanism according to one embodiment of the present disclosure.

[0044] like Figure 3-6As shown, in the present disclosure, the supporting mechanism 2 includes a fixed plate 21, a slide bar 22, a supporting plate 23, a lower trapezoidal block 24, an upper trapezoidal block 25, a mounting groove 26, a first magnetic block 27, a spring 28 and a second magnetic block 29, wherein the fixed plate 21 is fixedly connected to the top of the operating table body 11, the slide bar 22 is fixedly connected to the top of the fixed plate 21, the supporting plate 23 is slidably sleeved on the outside of the slide bar 22, the lower trapezoidal block 24 is fixedly connected to the top of the fixed block, the upper trapezoidal block 25 is fixedly connected to the bottom of the supporting plate 23, the mounting groove 26 is opened on the upper surface of one end of the lower trapezoidal block 24, the first magnetic block 27 is fixedly connected to the surface of one end of the lower trapezoidal block 24 and is located on the outside of the mounting groove 26, one end of the spring 28 is fixedly connected to the lower trapezoidal block 24 and is located inside the mounting groove 26, the other end of the spring 28 is fixedly connected to the bottom of the upper trapezoidal block 25, and the second magnetic block 29 is fixedly connected to the bottom of one end of the upper trapezoidal block 25.

[0045] Therefore, when the operator needs the tray 15 to move upward for operation, the operator moves the supporting wedge block 34 forward to drive the upper trapezoidal block 25 to move upward, while stretching the spring 28 and separating the first magnetic block 27 and the second magnetic block 29. The upper trapezoidal block 25 moves upward to drive the supporting plate 23 to slide upward on the slide bar 22, and the supporting plate 23 drives the mounting seat 14 and the tray 15 to move upward. At this time, the operator can perform piston processing operations. When the operator needs the tray 15 to move downward for operation, the operator opens the crank mechanism 3 to make the supporting wedge block 34 move backward. When the supporting wedge block 34 moves backward, the upper trapezoidal block 25 loses support. At this time, under the reset action of the spring 28 and the adsorption action of the first magnetic block 27 and the second magnetic block 29, the upper trapezoidal block 25 can move downward quickly and smoothly while driving the supporting plate 23 to slide downward. The supporting plate 23 slides downward to drive the mounting seat 14 and the tray 15 to move downward, and the operator can continue to perform piston processing operations.
