[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0021] like Figures 1 to 2As shown, a product pre-installation mechanism includes a fixing component 1 and a bracket 2. The bracket 2 is connected to the fixing component 1 for sliding up and down through two limiting guide rods 3, and the limiting guide rods 3 are set at an angle to the vertical direction; a number of positioning support columns 4 are distributed on the bracket 2, and a locking member 5 is detachably connected to the positioning support surface of the positioning support column 4; a vertical connecting rod 6 is connected to the bottom of the bracket 2, and the lower end of the connecting rod 6 is in sliding contact with a rotating wheel 7, and the rotating wheel 7 is connected to a driving component 8 that drives it to rotate eccentrically around the horizontal direction.

[0022] Specifically, the fixing assembly 1 includes two fixing blocks 11, and one fixing block 11 is connected to a limiting guide rod 3. The fixing block 11 is installed on the tool body.

[0023] Among them, the bottom surface of the bracket 2 is connected to a T-shaped block 21, and the lower end of the T-shaped block 21 is provided with a socket for inserting the upper end of the connecting rod 6. The side of the T-shaped block 21 is provided with a pin hole 211 connected to the socket, and a limit pin is provided in the pin hole 211 for limiting the connecting rod 6.

[0024] Furthermore, the positioning support column 4 is arranged parallel to the limiting guide rod 3 , and a threaded section is provided at the lower end of the positioning support column 4 , which is screwed into a threaded hole provided on the top surface of the bracket 2 .

[0025] It should be noted that a plurality of threaded holes may be provided on the top surface of the bracket 2. When in use, a corresponding number of positioning support columns 4 may be selected according to product specifications, and the positioning support columns 4 may be screwed into the corresponding threaded holes.

[0026] In order to reduce the weight of the bracket 2, the bracket 2 may be hollowed out.

[0027] In the product pre-installation mechanism, the locking member 5 is preferably a head screw whose lower end is threaded into the positioning support column 4.

[0028] In the product pre-assembly mechanism, the lower end surface of the connecting rod 6 is preferably a hemispherical surface protruding outward, so that the connecting rod 6 and the side surface of the rotating wheel 7 are in point contact to reduce the contact area.

[0029] In the pre-installation mechanism of this product, the driving component 8 includes a driving rod 81 horizontally rotatably arranged on the fixed seat 9, wherein the fixed seat 9 and the fixed component 1 are relatively fixedly arranged on the tooling body; one end of the driving rod 81 is eccentrically connected to the rotating wheel 7, and the other end is coaxially connected to the connecting block 82, and the side of the cover connecting block 82 is connected to two rotating rods 83 set at an angle; limit blocks 84 are respectively provided on both sides of the connecting block 82, and these two limit blocks 84 limit the rotation of the two rotating rods 83.

[0030] During use, the rotating rod 83 is driven to rotate, which can drive the driving rod 81 to rotate, thereby causing the rotating wheel 7 to rotate eccentrically around the horizontal direction.

[0031] Furthermore, the two limit blocks 84 are symmetrically arranged relative to the rotation center axis of the driving rod 81.

[0032] In order to facilitate the operation of the rotating rod 83, a spherical handle 85 can be provided at one end of the rotating rod 83 away from the connecting block 82. Preferably, the angle between the two rotating rods 83 is 90 degrees.

[0033] The present invention provides a product pre-assembly mechanism. When in use, a product is placed on each positioning support column 4 and secured to the corresponding positioning support column 4 via a locking member 5. Driven by a drive assembly 8, a rotating wheel 7 rotates eccentrically about the horizontal direction, causing a connecting rod 6 to move upward. This in turn causes the bracket 2 and the product fixed thereto to move upward along two limiting guide rods 3, thereby precisely moving the product into position for easy assembly. This product pre-assembly mechanism improves product assembly accuracy, reduces assembly difficulty, and facilitates product placement.

[0034] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
