DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1-5 As shown, the utility model can solve the problems of low working efficiency and easy damage to products of existing matching riveting tools, and provides the following technical solutions: a synchronous water pipe riveting tool for automobile thermal management system accessories, comprising a base plate 1, a mounting seat 7 is arranged in the middle of the upper side of the base plate 1, a product support plate 8 is installed on the upper end of the mounting seat 7, a plurality of vertically slidable positioning support columns 14 are vertically arranged in the mounting seat 7, the position of the positioning support column 14 corresponds to the position of the water pipe head B to be installed, and an elastic member 15 is arranged at the lower end of the positioning support column 14, the positioning support column 14 can position and support the water pipe head B, and drop when the water pipe head B is under pressure, so as to accurately assemble the water pipe head B to the corresponding position on the product A;

[0024] It also includes an upper plate 2, a pressing plate 3 is connected to the lower side of the upper plate 2, a guide rod 13 is vertically passed through the position of the pressing plate 3 corresponding to the positioning support column 14, a nitrogen spring 4 is installed between the upper end of the guide rod 13 and the upper plate 2, a riveting head 6 is installed at the lower end of the guide rod 13, the nitrogen spring 4 has a certain buffering capacity, and can effectively prevent the product from being deformed by excessive instantaneous pressure when the upper plate 2 is pressed down.

[0025] Specifically, when riveting, first place product A on the product support plate 8, limit the position through the positioning support column 14, and then place the water pipe head B on the step at the top of the positioning support column 14. At this time, product A and water pipe head B are not in contact, leaving a gap; multiple handles 18 are installed on the side of the bottom plate 1 to facilitate the movement of the entire tooling.

[0026] Next is the operation of the equipment. The upper plate 2 is connected to the press, and the press drives the upper plate 2 to press down. The riveting head 6 contacts the water pipe head and begins to generate force. The water pipe head B is squeezed downward and the force increases. At this time, the nitrogen spring 4 intervenes and takes effect. The nitrogen spring has a certain buffering capacity and can effectively prevent the instantaneous excessive pressure from deforming the product. The upper plate 2 and the pressing plate 3 continue to move downward under the action of the press. The water pipe head B is positioned and steadily pressed into the hole on the product A through the positioning support column 14, and the elastic member 15 is compressed.

[0027] After pressing down into place and maintaining the pressure for a period of time, the upper plate 2 is lifted up, the elastic member 15 is released, the positioning support column 14 is lifted up, and the riveted product A is lifted up to facilitate the removal of the product.

[0028] In this embodiment, the upper plate 2 and the pressure plate 3 are connected by connecting rods 5 arranged at both ends of the pressure plate 3, so that enough space can be left between the upper plate 2 and the pressure plate 3 to install the nitrogen spring 4, and the length of the connecting rod 5 corresponds to the length of the nitrogen spring 4.

[0029] In order to limit the position of the guide rod 13, a limiting plate 16 is provided at the upper end of the pressure plate 3. The upper end of the guide rod 13 passes through the limiting plate 16 and is installed with a limiting gasket 17. The lower end of the nitrogen spring 4 abuts against the limiting gasket 17. The limiting gasket 17 can prevent the guide rod 13 from detaching from the pressure plate 3, thereby playing a limiting role.

[0030] In order to limit the downward stroke of the upper plate 2, lower supports 9 are installed at both ends of the mounting seat 7, and upper supports 10 corresponding to the lower supports 9 are arranged at both ends of the lower side of the pressing plate 3. When the lower supports 9 and the upper supports 10 are against each other, the upper plate 2 cannot be pressed down, which plays the role of stroke limit. At the same time, a guide column 11 and a guide hole are arranged between the lower supports 9 and the upper supports 10 to guide the downward pressing action of the upper plate 2.

[0031] In order to ensure the stability of the positioning support column 14 and the guide rod 13 during axial movement, the outer sides of the positioning support column 14 and the guide rod 13 are sleeved with linear bearings 12 to ensure that the positioning support column 14 and the guide rod 13 can move axially smoothly without deviation.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
