Technical Field

[0001] The present application relates to the field of presses, and in particular to a servo press that is easy to operate. Background Art

[0002] A servo press is a device that presses one component into another, such as a shaft into a balancing block, a shaft into an iron core, a shaft into an impeller, or a shaft into a bearing.

[0003] In the related art, the servo press includes a tooling, which includes a servo drive unit, a pressing unit, a placement platform and a backrest. The backrest is used to limit the first component and place the second component on the placement platform. The servo drive unit drives the pressing unit to move closer to press the first component into the second component.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there are the following defects: it is difficult to press the first component into the second component by only placing the second component on the placement platform. Utility Model Content

[0005] In order to reduce the cost of a servo press that is easy to operate, the present application provides a servo press that is easy to operate.

[0006] The present application provides a conveniently operated servo press adopting the following technical solution:

[0007] A servo press with easy operation includes a frame, a pressing part, a backrest, an elastic part and a positioning part. The pressing part is slidably connected to the frame, and a sliding direction is defined. The sliding direction is the direction in which the pressing part slides. Along the sliding direction, the backrest is located between at least part of the pressing part and the positioning part; the positioning part is slidably connected to the frame along the sliding direction, one end of the elastic part is connected to the positioning part, and the other end of the elastic part is connected to the frame, and the positioning part at least partially passes through the frame.

[0008] By adopting the above technical solution, when in use, the operator only needs to put the second component on the positioning part for positioning. After the first component is pressed into the second component, the elastic part pops the assembled first component and the second component out of the frame, which is convenient for the operator to operate.

[0009] Optionally, the elastic portion includes a driving spring, one end of the driving spring is connected to the frame, and the other end of the driving spring is connected to the positioning portion.

[0010] By adopting the above technical solution, the structure is simple and it is convenient to discharge the assembled first component and the second component.

[0011] Optionally, the servo press includes a mounting portion, which is fixedly connected or limit-connected to the frame, the mounting portion has a mounting groove, the positioning portion is at least partially located in the mounting groove, the mounting portion at least partially passes through the mounting portion, and the elastic portion is located in the mounting groove.

[0012] By adopting the above technical solution, during installation, the elastic part and the positioning part are slid into the installation groove, and then the installation part is fixedly connected or limit-connected to the frame, which is convenient for installation.

[0013] Optionally, the servo press includes a mounting bolt, the tail of which passes through the mounting portion and is threadedly connected to the frame; the servo press includes a positioning column, which extends along the sliding direction, and the mounting portion is sleeved on the positioning column.

[0014] By adopting the above technical solution, when the mounting part needs to be installed on the frame, the operator only needs to slide the mounting part onto the positioning column to facilitate the alignment of the holes on the mounting part and the holes on the frame.

[0015] Optionally, the servo press includes a blocking part and a moving block, the blocking part is located between the mounting groove and the backrest, the positioning part is arranged through the blocking part, the moving block is located in the mounting groove, the moving block is located on the side of the blocking part away from the backrest, the moving block is connected to the positioning part, one end of the elastic part is connected to the frame, and the other end of the elastic part is connected to the moving block.

[0016] By adopting the above technical solution, the blocking part blocks the moving block, the structure is simple, and the positioning part can be maintained in a state of passing through the blocking part, thereby reducing the occurrence of the positioning part falling out of the installation groove.

[0017] Optionally, the mounting portion has a protrusion, which protrudes from the mounting portion in a direction close to the backrest, the protrusion has the mounting groove, the frame portion is exposed to the mounting groove, the blocking portion has a plane, the positioning portion is used to penetrate the second component, and the plane is used to place the second component.

[0018] By adopting the above technical solution, when in use, the plane supports the second component, reducing the contact between the second component and the large plane of the mounting portion. The second component is supported only by the plane, reducing the processing accuracy of the plane and reducing costs.

[0019] Optionally, in a normal state, the positioning portion has a first end, and the first end is located in the second component.

[0020] By adopting the above technical solution, during the contact between the first component and the first end, the first component is first pressed into the second component part and then contacts the first end, thereby reducing the impact of the first component on the first end and reducing the damage to the positioning part.

[0021] Optionally, the positioning portion has a threaded portion, the threaded portion is threadedly connected to the moving block, and the moving block is circumferentially clamped with the mounting groove.

[0022] By adopting the above technical solution and rotating the positioning part, the second components with different thicknesses can be positioned.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The positioning part and the elastic part facilitate the positioning of the second component and the operation;

[0025] 2. Through the mounting part, mounting groove and mounting bolts, the positioning part and the elastic part are conveniently installed on the frame;

[0026] 3. The second component with different thickness can be positioned by the threaded portion. BRIEF DESCRIPTION OF THE DRAWINGS
