Description

Technical Field

[0001] The utility model relates to an in-hole device installation technology, in particular to a valve core assembly unit and a door closer assembly tool. Background Art

[0002] Assembly tooling is an important auxiliary tool for completing the assembly work after product processing. It is an indispensable and important component when designing the assembly process. Suitable assembly tooling can significantly improve the assembly quality of the product, improve assembly efficiency, and reduce manual labor intensity. The utility model is used for assembling in-hole parts. Generally, the assembly of this type of parts requires the positioning of the workpiece, the clamping of the parts to be assembled, and the coordination with the assembly position. Common assembly tooling for inner hole accessories is non-standard and is customized according to the specific situation during assembly. The simple implementation scheme similar to the utility model is generally to install the parts into position by a slender rod with a positioning function, or to clamp the parts by long tweezers.

[0003] For example, the prior art CN202220371926.1 discloses a top plate and side plates arranged on both sides of the top plate, the bottom of the two side plates are both provided with mounting plates, one side of the top plate is provided with a clamping end, one side of the side plate is provided with a clamping pile, an adjustment hole is provided at the top center end of the top plate, a cap for adjusting the opening and closing degree of the pressure valve is rotatably connected to the inside of the adjustment hole, a limiting hole is provided on one side of the bottom of the side plate, a blocking cap for installing the rotating shaft is clamped inside the limiting hole.

[0004] The functions of rapid positioning and accessory rotation cannot be met. For example, using a slender rod can only install the part into a specific position, but cannot keep the part in place in the inner hole and flip it at a specific angle. The same is true for slender tweezers gripping parts for assembly. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art in that the valve core of the door closer is difficult to install, the installation is complicated, and the installation efficiency is affected, and provides a valve core assembly unit and a door closer assembly tool.

[0006] A valve core assembly unit comprises an assembly body, and is characterized in that the assembly body comprises a positioning unit for positioning the valve core and a lever unit for shifting the positioning unit.

[0007] The valve core is positioned by driving the positioning unit through the lever unit, which is simple to operate and easy to install.

[0008] Preferably, the positioning unit includes a positioning sleeve rod, a slider and a clamping claw. The positioning sleeve rod is fixedly connected to the clamping claw, and the slider is located in the cavity of the positioning sleeve rod and connected to the clamping claw. A push rod is provided in the positioning sleeve rod, one end of the push rod is connected to the lever unit, and the other end is connected to the slider. The positioning rod is moved by tossing the lever unit, and the movement of the positioning rod drives the sliding of the slider, and the sliding slider controls the opening and clamping of the clamping claw.

[0009] Preferably, the clamp includes an upper jaw unit and a lower jaw unit, which are provided with a boss positioning hole, a limiting hole, an adjustment hole and a slider groove in sequence. The boss positioning hole is provided with a valve core positioning boss, and the limiting hole is used to limit the upper jaw unit and the lower jaw unit; the adjustment hole is connected to an elastic adjustment unit for adjusting the opening angle of the upper jaw unit and the lower jaw unit, and the slider groove is used to place the end of the slider.

[0010] Preferably, the upper claw unit and the lower claw unit are further provided with a limiting groove near the slider groove, and the limiting groove is connected to the limiting pin.

[0011] Preferably, the slider is concave, and both protrusions of the concave slider are wedge-shaped. By providing the wedge-shaped protrusions, one protrusion can be directly placed in the slider groove of the upper jaw unit, and the other protrusion can be directly placed in the slider groove of the lower jaw unit; thus, the opening angle of the clamping jaws can be adjusted by the slider.

[0012] Preferably, a push rod elastic limiting unit is provided on one end of the push rod close to the toggle unit.

[0013] In order to solve the above technical problems, the utility model further provides a door closer assembly tool, including a tooling table, on which the valve core assembly unit is connected.

[0014] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0015] The utility model adopts the above technical solution, which has the following significant technical effects:

[0016] The utility model toggles a lever unit, which drives a push rod in a positioning sleeve in a positioning unit. The push rod pushes a slider to slide, and the sliding of the slider adjusts the opening angle of the clamping jaws. When the jaws are opened at a large angle, the valve core is placed in the clamping jaws. Since the lever unit automatically resets when not toggled, the push rod pulls back the slider, thereby reducing the opening angle of the clamping jaws and fixing the valve core in the clamping jaws. At the same time, since a boss is provided at the end of the clamping jaws, the two holes of the valve core are exactly connected to the boss, which further facilitates the fixing of the valve core. After the valve core is fixed, the valve core can be rotated to a certain angle by toggling Zheng to facilitate the installation of the door closer.

[0017] The utility model has simple installation operation for the valve core and the door closer and is convenient to install. BRIEF DESCRIPTION OF THE DRAWINGS
