Description

Technical Field

[0001] The utility model belongs to the technical field of assembly tooling, and in particular relates to a pin-key auxiliary installation tool. Background Art

[0002] Pins and keys are commonly used connectors in the assembly of mechanical products. Generally, pins and pin holes, and keys and keyways, have an interference fit. Assembly methods include pressing, hammering, and hot / cold assembly. Whether pressing or hammering, the pin / key and pin hole / keyway must remain perpendicular. Misalignment can damage either the pin / key or the pin hole / keyway (the damage depends on the hardness of the materials used; softer materials are more prone to burring or deformation), impacting service life and even compromising assembly precision.

[0003] In addition, when the pin key is large and needs to be struck with a copper rod or aluminum rod, the operator will swing his arm due to the heavy weight of the tool itself. If the operator is not skilled, it is difficult to accurately control the landing point. The operator will either strike the workpiece to be installed directly, or the fingers holding the copper rod or aluminum rod will hit the pin key and get injured. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a pin key auxiliary installation tool, which is used to solve the technical problems in the existing pin key assembly process, such as the difficulty in ensuring the assembly effect by using the pressing or knocking assembly method, and the difficulty in accurately controlling the landing point of the knocking rod during the knocking assembly.

[0005] The technical solution of the utility model to solve the above technical problems is as follows: a pin key auxiliary installation tool, comprising:

[0006] A C-shaped bracket, wherein the upper end of the C-shaped bracket is provided with a screw sleeve, and the lower end of the C-shaped bracket is provided with a fixing seat;

[0007] a screw, the screw being screwed into the sleeve;

[0008] A handle connected to the head end of the screw;

[0009] A pressing block connected to the tail end of the screw;

[0010] The fixing seat is Y-shaped, and the orthographic projection of the pressing block falls within the opening of the Y-shape.

[0011] The utility model utilizes the up and down movement of a rotating screw to convert the rotational force into a pressing force, which can not only output the pressing force steadily, but also utilize the bottom surface of the pressing block to contact the top surface of the pin / key, so that the pin / key can remain in a vertical state and can be accurately embedded in the pin hole or keyway.

[0012] Furthermore: the top surface of the fixing base is provided with an anti-slip pad, and the bottom surface of the fixing base is provided with a magnetic base.

[0013] The beneficial effect of adopting this step is that the workpiece to be mounted can be placed above or below the fixed seat.

[0014] Furthermore: a through hole is opened in the arc section of the C-shaped bracket.

[0015] The beneficial effect of adopting this step is that the through hole is used to hold the C-shaped bracket.

[0016] Furthermore: the edge of the through hole is also wrapped with a rubber sleeve.

[0017] The beneficial effect of adopting this step: the rubber sleeve has an anti-slip effect.

[0018] Furthermore: protruding upper ear plates are provided on both sides of the screw sleeve, and protruding lower ear plates are provided on both sides of the fixing seat, and the positions of the upper ear plates and the lower ear plates correspond to each other;

[0019] A reinforcing connecting rod is provided between the upper ear plate and the lower ear plate.

[0020] The beneficial effect of adopting this step is that the overall structural strength of the C-shaped bracket can be enhanced by strengthening the combination of the connecting rod, the upper ear plate and the lower ear plate.

[0021] Furthermore: the top surfaces of the upper ear plate and the lower ear plate are provided with reinforcing ribs.

[0022] The beneficial effect of adopting this step is that the reinforcing ribs can enhance the structural strength of the upper ear plate and the lower ear plate.

[0023] Furthermore: a limiting ring is provided in the opening of the fixing seat, and the limiting ring is aligned with the pressing block;

[0024] An elastic inner gear ring is provided in the limiting ring.

[0025] The beneficial effect of adopting this step is: the pin can be embedded in the elastic inner gear ring, and then the limit ring is placed on the workpiece to be installed, and the pin is aligned with the pin hole, so that the pin does not need to be supported by hand.

[0026] The beneficial effects of the utility model are:

[0027] 1. This application can use a screw to drive the pressing block to move downward to press the pin / key to achieve an interference fit; first, the pressing block can output downward force steadily by rotating the screw, and secondly, the pressing block contacts the pin / key to keep the pin / key in a vertical state;

[0028] 2. This application can ensure the assembly effect of the pin / key and there is no safety hazard;

[0029] 3. The fixing seat of the present application can also adapt to workpieces of different thicknesses. Thin workpieces can be placed directly on top of the fixing seat, and thick workpieces can be placed under the fixing seat, and the two are kept connected by the magnetic seat.
