Referring to fig. 1 to 4, the present invention discloses a caulking jig including a base 100, a pressing rod 300, a hinge rod 500, a handle 600, a pressing head 410, and an elastic buffer member 700.

The base 100 can stack the part 200 to be bonded, the rear portion of the pressing rod 300 is hinged to the base 100 through the first hinge shaft 310, one end of the hinge rod 500 is hinged to the base 100 through the second hinge shaft 510, the front portion of the handle 600 is hinged to the other end of the hinge rod 500 and the rear portion of the pressing rod 300 through the third hinge shaft 610 and the fourth hinge shaft 620, the pressing head 410 is movably connected to the front portion of the pressing rod 300 through the pressing column 400, when the handle 600 rotates relative to the base 100, the pressing column 400 can rotate, the pressing head 410 can be driven to press the part 200 to be bonded, and the elastic buffer member 700 penetrates through the pressing column 400 and is located between the pressing rod 300 and the pressing head 410.

It can be understood that, in use, the part 200 to be bonded is stacked on the base 100, the pressing rod 300 can be in the glue pressing state by pulling the handle 600, and the pressing head 410 in the glue pressing state can be pressed on the part 200 to be bonded; after the glue between the parts 200 to be bonded is fully cured, the handle 600 is pulled in a reverse direction to open the pressing rod 300, and the pressing head 410 in the open state is far away from the parts 200 to be bonded. The glue pressing clamp can press and loosen the part 200 to be bonded only by pulling the handle 600, is simple and convenient to operate, and can effectively improve the glue pressing efficiency; because the handle 600 is pressed down to the right position and then the pressing force of the part 200 to be bonded is consistent, the pressing force can be kept consistent. In addition, the elastic buffer member 700 inserted into the compression leg 400 can buffer the pressure head 410 and the compression bar 300 when the pressure head 410 is pressed down onto the part 200 to be bonded, so as to prevent the surface of the part 200 to be bonded from being damaged by the excessive pressure of the pressure head 410.

Specifically, referring to fig. 1, when the rear portion of the handle 600 is pressed downward, the handle 600 may rotate the hinge lever 500 through the third hinge shaft 610 such that the other end of the hinge lever 500 rotates downward about the second hinge shaft 510, and at the same time, the handle 600 may push the pressing lever 300 forward through the fourth hinge shaft 620 such that the front portion of the pressing lever 300 rotates downward about the first hinge shaft 310 until the pressing head 410 presses against the surface of the part 200 to be bonded.

It should be noted that, when the pressing head 410 presses against the surface of the part 200 to be bonded, the base 100 can abut against the middle portion of the handle 600 to prevent the front end of the pressing rod 300 from tilting upward, and if the front end of the pressing rod 300 in the pressing state tilts upward, the pressing effect is affected. Specifically, when the handle 600 is pressed down, the handle 600 drives the other end of the hinge rod 500 to rotate downwards around the second hinge shaft 510 through the third hinge shaft 610, and the third hinge shaft 610 is located below the fourth hinge shaft 620, so that when the front end of the pressing rod 300 in the glue pressing state tilts upwards, the pressing rod 300 can drive the front end of the handle 600 to rotate upwards through the fourth hinge shaft 620, but because the middle part of the handle 600 at this time is already propped against by the base 100, the front end of the handle 600 cannot rotate upwards, and therefore the structure can prevent the front end of the pressing rod 300 from tilting upwards.

In addition, referring to fig. 2, after the glue between the parts 200 to be bonded is cured, the handle 600 may drive the other end of the hinge lever 500 to rotate upward through the third hinge shaft 610 by lifting up the rear portion of the handle 600, and at the same time, the handle 600 pulls the pressing lever 300 backward through the fourth hinge shaft 620 to rotate the front portion of the pressing lever 300 upward, so that the pressing head 410 is away from the parts 200 to be bonded.

It should be noted that the pressing head 410 may be made of elastic material such as rubber, so as to prevent scratching the surface of the part 200 to be bonded.

Referring to fig. 4, in some embodiments of the present invention, a positioning groove 110 for receiving a part 200 to be bonded is provided on a base 100. The positioning groove 110 can support and position the part 200 to be bonded, so as to prevent the part 200 to be bonded from moving in the glue pressing process. The positioning groove 110 can fix the relative position between the parts 200 to be bonded and the pressing column 400, so as to ensure that the pressed positions of the groups of parts 200 to be bonded are consistent.

Referring to fig. 4, in some embodiments of the present invention, a pad 800 is further included, the pad 800 is disposed in the positioning groove 110, and the pad 800 can support the part 200 to be bonded. When the distance between the pressing head 410 and the base 100 is fixed in the pressing state, if the thickness of the part 200 to be bonded is different, the lower surface of the pressing head 410 in the pressing state can be completely attached to the part 200 to be bonded by adding the cushion blocks 800 with different thicknesses to the bottom of the positioning groove 110.

Referring to fig. 3, in some embodiments of the present invention, the edge of the positioning groove 110 is provided with a handle 120 for grasping the part 200 to be bonded, the handle 120 may be an inclined groove, the groove needs to be communicated with the positioning groove 110, and the groove needs to be inclined downward from an end far away from the positioning groove 110 to an end near the positioning groove 110.

Referring to fig. 1 and 2, in some embodiments of the present invention, the elastic buffer 700 is a compression spring, and the compression spring in the glue pressing state is in a compressed state, and the compression spring can counteract the excessive acting force between the pressing head 410 and the part 200 to be bonded, so as to prevent the part 200 to be bonded from being damaged, and the compression spring is restored to its original state after the pressing head 410 is lifted. Further, the pressing head 410 can be close to or far from the pressing rod 300, specifically, the pressing rod 400 is fixedly connected with the pressing rod 300, and the pressing head 410 can slide relative to the pressing rod 400; alternatively, the compression column 400 is fixedly connected with the compression head 410, and the compression column 400 can slide relative to the compression rod 300.

Referring to fig. 1 and 4, in some embodiments of the present invention, when the pressing head 410 presses down the parts to be bonded 200, the pressing column 400 is in a vertical state, so that the force direction of the parts to be bonded 200 is a vertical direction, which is beneficial to compressing the parts to be bonded 200, and can prevent the parts to be bonded 200 from being dislocated.

In some embodiments of the utility model, the lower end of the compression leg 400 is hinged to the ram 410. When the pressing column 400 cannot be vertical in the glue pressing state due to limited space, the pressing head 410 is hinged to the pressing column 400, so that the pressing head 410 can be always attached to the surface of the part 200 to be bonded in the glue pressing state, and the part 200 to be bonded can be prevented from being dislocated.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
