Detailed implementation mode

[0034] The following will, in conjunction with the accompanying drawings, elaborate on a preferred embodiment of the present utility model.

[0035] Refer to Figures 1 to 5 , an embodiment of the product fastening device provided by the present utility model is used for the fastening and assembly of Component A1 and Component B2. A protrusion 101 is provided on the outer peripheral wall of Component A1, and Component B2 has a frame 201 adapted to the outer periphery of Component A1, and a hole 202 adapted to the protrusion 101 is provided on the frame 201. Among them, Component B2 is made of a material with deformation and reset ability, such as aluminum alloy. In addition, the structure of Component B2 can be as shown in the attached Figure 1 structure, or it can be a cover with a frame, and both can use this embodiment for fastening and assembly. For the fastening and assembly of the two components, the existing conventional connection method is adopted, that is, snap connection, or the fastening connection as shown in the attached Figure 1 .

[0036] Specifically, the product fastening device includes: a workbench 3, a product placement table 4, an expanding mechanism 5, and a separation and fastening mechanism 6; among them,

[0037] The workbench 3 has a horizontally arranged workbench surface 31; the product placement table 4 is arranged on the workbench surface 31 for placing Component A1;

[0038] The expanding mechanism 5 is arranged on the workbench surface 31 and is arranged at a set position beside the product placement table 4 to expand the frame 201 outward when Component B2 is assembled with Component A1;

[0039] The separation and fastening mechanism 6 is used to drive the component A1 to drive the component B2 to move vertically upward away from the expansion mechanism 5 when the convex portion 101 of the component A1 coincides with the hole 202 of the component B2, so that the convex portion 101 is placed in the hole 202 to achieve snap-fit assembly. That is, during the process of gradually bringing the component B2 into contact with the component A1 vertically downward, the outer frame 201 of the downward-moving component B2 is expanded outward by the expansion mechanism 5, so that the inner wall surface of the outer frame 201 does not rub hard against the convex portion 101 of the component A1, and at the same time, the hole 202 on the component B2 is aligned with the convex portion 101 on the component A1 to reach the pre-assembly state.

[0040] Then, in the pre-assembled state, the separation and fastening mechanism 6 drives the components A and B to move upward simultaneously, so that the outer frame 201 of the component B is separated from the expansion mechanism 5, and the outer frame 201 is reset under the action of the self-resetting ability, so that the hole 202 on it is fastened to the convex portion 101 of the component A1 to achieve automatic snap-fit assembly of the product, and at the same time, it is also convenient for the assembled product to be smoothly separated from the device.

[0041] Furthermore, the expansion mechanism 5 includes a fixed expansion unit 51 and a movable expansion unit 52.

[0042] Among them, the fixed expansion unit 51 includes a plurality of fixed expansion members 511. The plurality of fixed expansion members 511 are arranged at set positions beside two adjacent sides of the product placement table 4 at intervals. The fixed expansion member 511 includes a first base 5111 fixedly connected to the workbench surface 31 and a first expansion portion 5112 provided on the first base 5111. Specifically, in this embodiment, refer to Figure 3 , three fixed expansion members 511 are provided. Two of them are arranged at both ends of a long side of the product placement table 4 at intervals, and the other is arranged in the middle of a short side of the product placement table 4. The three fixed expansion members 511 form a right-angle positioning reference on the workbench surface 31, so that the component A1 placed on the product placement table 4 has a fixed positioning end. Of course, it can be understood that a plurality of fixed expansion members 511 can also be provided according to production requirements to achieve a better expansion effect on the component B2.

[0043] There are two sets of movable expanding units 52, which are respectively arranged on the sides adjacent to the other two adjacent sides of the product placing table 4. Each set of movable expanding units 52 includes at least one movable supporting member 521 and a horizontal driving assembly 53 for driving the movable supporting member 521 to approach or move away from the product placing table 4. The horizontal driving assembly 53 includes a first driving cylinder 531 arranged on the workbench surface 31 in the horizontal direction and a driving plate 532 connected to the piston rod 5311 of the first driving cylinder 531; sliders 533 are arranged on the lower sides of the two ends of the driving plate 532 parallel to its moving direction, and two slide rails 534 adapted to the sliders 533 and arranged parallel to the piston rod 5311 are arranged on the workbench surface 31; the movable supporting member 521 includes a second base 5211 fixedly connected to the driving plate 532 and a second expanding part 5212 arranged on the second base 5211. Specifically, each set of movable expanding units 52 is respectively driven by the corresponding horizontal driving assembly 53 to move the movable supporting member 521 thereon in the horizontal direction, so that the device can be applied to the snap assembly of products of different sizes by replacing the product placing table 4.

[0044] Furthermore, a guiding groove hole 311 is formed on the workbench surface 31 along the stroke path of the driving plate 532, and a limiting plate 5321 slidably matched with the guiding groove hole 311 is connected to the lower end surface of the driving plate 532. Through the arrangement of the limiting plate 5321 and the slide rail 534, the driving plate 532 can move linearly in the horizontal direction, so as to ensure that the movable supporting member 521 arranged on the driving plate 532 also moves in the same straight line; in addition, the two sets of movable expanding units 52 are respectively arranged close to the other two sides of the product placing table 4, so as to fix the outer peripheral wall of the component A1 in cooperation with the fixed expanding unit 51 when the component A1 is placed on the product placing table 4, ensure that the position of the component A1 remains fixed when the component B2 is snapped and assembled downward, and ensure the coincidence of the protruding part 101 of the component A1 and the hole 202 of the component B2.

[0045] Furthermore, the first expanding part 5112 includes a first vertical surface 51121 and a first guiding surface 51122. The first vertical surface 51121 extends vertically upward from the inner side wall surface of the first base 5111, and the first guiding surface 51122 is arranged on the side opposite to the first vertical surface 51121 and is inclined downward and outward from top to bottom;

[0046] The second expanding part 5212 includes a second vertical surface 52121 and a second guiding surface 52122. The second vertical surface 52121 extends vertically upward from the inner side wall surface of the second base 5211, and the second guiding surface 52122 is arranged on the side opposite to the second vertical surface 52121 and is inclined downward and outward from top to bottom. The horizontal distance between the lowermost end of the first guiding surface 51122 and the first vertical surface 51121 is at least equal to the protruding height of the protruding part 101;

[0047] The horizontal distance between the lowermost end of the second guiding surface 52122 and the second vertical surface 52121 is at least equal to the protruding height of the protruding portion 101.

[0048] Specifically, the first expanding portion 5112 and the second expanding portion 5212 provided in this embodiment have the same structure. When the component A1 is positioned on the product placing table 4, the first vertical surface 51121 and the second vertical surface 52121 are in close contact with the outer peripheral wall surface of the component A1. Moreover, the arrangement of the first vertical surface 51121 and the first guiding surface 51122 makes the top of the first expanding portion 5112 approximately linear; the arrangement of the second vertical surface 52121 and the second guiding surface 52122 makes the top of the second expanding portion 5212 approximately linear. Thus, when the fitting clearance between the component A1 and the component B2 is small, the clearance between the inner wall surface of the frame 201 of the component B2 and the outer peripheral wall surface of the component A1 is sufficient to accommodate the approximately linear top portion therein. At the same time, when the hole 202 coincides with the position of the protruding portion 101, the frame 201 will not be overly expanded, enabling the frame 201 to have the ability to recover to its original state.

[0049] Preferably, the fixed support member 511 and the movable support member 521 are correspondingly arranged with the protruding portion 101 on the component A1. In addition, two first expanding portions 5112 are arranged at intervals on the first base 5111, and two second expanding portions 5212 are arranged at intervals on the second base 5211. Moreover, the protruding portion 101 at the corresponding position is exactly located between the two first expanding portions 5112 and the two second expanding portions 5212, that is, the two first expanding portions 5112 and the two second expanding portions 5212 are also exactly located on both sides of the hole 202 corresponding to the frame 201, thereby ensuring the effective expansion of the frame 201 and preventing hard rubbing between the protruding portion 101 and the frame 201.

[0050] Furthermore, a through hole 312 is provided on the work surface 31, and the through hole 312 is located directly below the product placement table 4 and penetrates the support plate 41; the separation and fastening mechanism 6 includes a second driving cylinder 61 provided directly below the through hole 312, and the piston rod 611 of the second driving cylinder 61 vertically passes through the through hole 312 upwards, and is connected to the lower end surface of the positioning carrier 42 through the lifting plate 62. Specifically, guide columns 43 are provided on both sides of the work surface 31 near the through hole 312, and the positioning carrier 42 is slidably connected to the support plate 41 through the guide columns 43, so as to ensure the movement of the positioning carrier 42 in the vertical direction. In addition, when the second driving cylinder 61 drives the positioning carrier 42 to move upward, due to the inclined guide surface of the opening part, when the positioning carrier 42 drives the parts A and B to move upward synchronously, the frame of the part B gradually retracts inward until the part B is reset and fastened to the part A1 when it is separated from the opening mechanism 5, and the fastening assembly of the product is completed. The lifted positioning carrier 42 is also helpful for the operator to remove the finished snap-fit ​​assembled product from the device.

[0051] Furthermore, the device further includes a pneumatic control mechanism 7, which is used to provide a stable air source for the first driving cylinder 531 and the second driving cylinder 61, and to control the actions of the first driving cylinder 531 and the second driving cylinder 61 respectively:

[0052] The pneumatic control mechanism 7 includes a pneumatic switch 71 and a gas pressure stabilizing unit 72. The air pipe and air source not shown in the figure, and the connection between the air pipe and the first driving cylinder 531 and the second driving cylinder 61 are the same as the prior art and will not be repeated here.

[0053] In summary, the product snap-fitting device provided by the utility model, by providing an opening mechanism to open the frame outward, thereby avoiding the problem of scratches and burrs caused by hard contact during product assembly, thereby improving the product assembly quality; by providing a separation snap-fitting mechanism, automatic snap-fitting assembly of the product is achieved, and at the same time, it is convenient to remove the product from the device after assembly, thereby improving the assembly efficiency of the product.
