The pressing mechanism 2 includes a pressing head 21 correspondingly disposed above the guide column 122 and movably disposed in the up-down direction relative to the seat body 11. The downward movement of the pressing head 21 can cause the guide column 122 to move downward and the elastic member 121 to be compressed. Then, the pressing head 21 moves upward, and the guide column 122 will be reset upward under the action of the elastic member 121.

[0035] Combination Figure 6-7 As shown, when the pressing device 10 is used to press and assemble the product 20, the first component 201, the second component 202, the third component 203 and the fourth component 204 of the product 20 are first sleeved on the periphery of the guide pillar 122 in sequence, so that the guide pillar 122 limits the positions of the first component 201, the second component 202, the third component 203 and the fourth component 204; then the pressing head 21 moves downward to press and assemble the first component 201, the second component 202, the third component 203 and the fourth component 204 together, and during this process, the guide pillar 122 also moves downward accordingly; after the pressing is completed, the pressing head 21 moves upward, and the guide pillar 122 is reset upward under the action of the elastic member 121. The upper end of the guide pillar 122 can be conical or hemispherical, so that the first component 201, the second component 202, the third component 203 and the fourth component 204 can be sleeved on its periphery.

[0036] In the product 20 assembled by the above-mentioned pressing device 10, the first component 201, the second component 202 and the fourth component 204 are plastic components, and the third component 203 is a spring. It is understandable that the structure of the product that can be pressed by the pressing device 10 provided in this embodiment is not limited to this, and can also be other structures. In this embodiment, the elastic member 121 is a helical compression spring, and its outer diameter is substantially the same as the inner diameter of the guide column 122. In other embodiments, the elastic member 121 can also be other parts that can be elastically retracted, which is not limited here.

[0037] Specifically, the seat body 11 includes a seat body 111, a pillar 112 disposed in the seat body 111 and extending in the up-down direction, a guide pillar 122 sleeved on the periphery of the pillar 112, and the upper and lower ends of the elastic member 121 respectively abut against the guide pillar 122 and the pillar 112, and the pillar 112 guides the guide pillar 122 to limit the movement of the guide pillar 122 in the up-down direction. The guide pillar 122 is specifically located above the pillar 112, and a blind hole is opened from its lower end surface to be hollow.

[0038] An inner hole 13 is provided in the seat body 111, and the inner hole 13 extends in the up-down direction and at least passes through the upper end surface of the seat body 111, so that the guide column 122 can extend out of the seat body 111 from the upper end surface of the seat body 111.

[0039] The inner hole 13 further includes a third hole section 133 located above the second hole section 132. The diameter of the third hole section 133 is larger than the diameter of the second hole section 132. The third hole section 133 can accommodate a certain component (for example, Figure 7 The first component 201 of the product 20 is formed so that the pressing device 10 can press and assemble the product 20.

[0040] The seat body 111 also includes a limiting groove 14 formed on its upper end surface near the third hole section 133. The limiting groove 14 is used to position a certain component (for example, Figure 7 The first component 201 of the product 20 is limited to prevent the component from rotating during pressing.

[0041] In this embodiment, the fixture seat 1 includes a plurality of floating components 12, and the pressing mechanism 2 includes a support 22 erected on one side of the fixture seat 1, a transfer plate 23 movably connected to the support 22 in the up-down direction, a plurality of press heads 21 connected to the transfer plate 23, and a driving member 24 connecting the support 22 and the transfer plate 23 to drive the transfer plate 23 to move up and down relative to the support 22. The plurality of press heads 21 and the guide posts 122 of the plurality of floating components 12 are arranged one by one in the up-down direction. The driving member 24 drives the transfer plate 23 to move downward, so that the plurality of press heads 21 can move downward together, so that the pressing device 10 can complete the assembly of a plurality of products 20 at one time. The number of floating components 12 and press heads 21 is determined according to the actual production requirements. In this embodiment, a fixture seat 1 is specifically provided with 12 floating components 12, and correspondingly, 12 press heads 21 are also provided, so that the pressing device 10 can complete the assembly of 12 products 20 at one time.

[0042] The inner hole 13 penetrates to the lower end surface of the seat body 111. The seat body 11 also includes a fixing plate 15 disposed below and connected to the plurality of pillars 112. The fixing plate 15 is connected to the seat body 111, so that the plurality of pillars 112 can be fixed in the seat body 111.

The fixing plate 15 can be embedded in the seat body 111 and arranged flush with the lower end surface of the seat body 111.

[0043] Specifically, the pressing device 10 further includes a slide rail 25 connected to the support 22 and extending in the up-down direction, a slider 26 slidably connected to the slide rail 25 in the up-down direction, a slide plate 27 connected to the slider 26, the slide plate 27 can move up and down with the slider 26, and the transfer plate 23 is connected to the slide plate 27 and can move up and down with the slide plate 27. The slide rail 25 and the slider 26 can be standard parts on the market, so that the up-down movement of the transfer plate 23 is smooth and stable.

[0044] The support 22 includes two supporting plates 221 arranged opposite to each other, a first connecting plate 222 and a second connecting plate 223 connecting the two supporting plates 221 , wherein the second connecting plate 223 is located above the first connecting plate 222 , the slide rail 25 is connected to the first connecting plate 222 , and the driving member 24 is connected to the second connecting plate 223 .

[0045] Furthermore, the driving member 24 is a toggle clamp, which is a common standard part on the market, and includes a wrench portion that can be turned by an operator. The operator can manually drive the transfer plate 23 to move up and down by turning the wrench portion, and the toggle clamp can amplify the operator's power through a lever effect, so that the operator can press and assemble multiple products 20. Compared with the solution of using a cylinder or a linear motor, the use of a toggle clamp as the driving member 24 does not require the use of any electrical components, thereby simplifying the structure of the pressing device 10.

[0046] The pressing mechanism 2 further includes a protective cover 28 which is arranged on the periphery of the transfer plate 23 . The protective cover 28 can prevent the operator from being crushed by the transfer plate 23 as a movable part during operation, thereby improving the safety of the pressing device 10 .

[0047] The pressing device 10 also includes a base plate 3, and the pressing mechanism 2 and the jig seat 1 are both arranged on the base plate 3. The jig seat 1 and the base plate 3 can be separated. When the pressing device 10 is in use, the operator can first separate the jig seat 1 from the base plate 3 so that the various components of the product 20 can be sleeved on the periphery of the guide column 122. After the various components of the product 20 are sleeved, the jig seat 1 is placed on the base plate 3; the pressing device 10 also includes a limit block 31 arranged on the base plate 3, and the limit block 31 is used to limit the position of the jig seat 1. Each time the operator places the jig seat 1 on the base plate 3, the limit block 31 can be used to limit the jig seat 1 to a preset position.

[0048] The support 22 is located at one side of the jig seat 1 in the width direction, and the limit block 31 includes a first limit block 311 and a second limit block 312 respectively located at both sides of the length direction of the jig seat 1, and a third limit block 313 located at one side of the width direction of the jig seat 1. The first limit block 311, the second limit block 312 and the third limit block 313 can jointly limit the jig seat 1 to a preset position. The first limit block 311 and the second limit block 312 are provided with inclined surfaces for guiding on both side surfaces close to each other, so that the jig seat 1 can enter the preset position defined by the limit block 31.

[0049] Furthermore, considering that it takes a long time for the operator to put the various components of the product 20 on the periphery of the guide column 122, while it takes a short time for the pressure head 21 to press down, the pressing device 10 includes a plurality of jig seats 1. In actual production, the plurality of jig seats 1 can be used by a plurality of operators at the same time, so that the various components of the product 20 can be put on the periphery of the guide columns 122 of a plurality of jig seats 1 at the same time. In this way, when the pressing device 10 is used to produce the product 20, the manpower layout is more reasonable.

[0050] In summary, the pressing device 10 proposed by the present invention has the following advantages:

[0051] 1. The structure is simple, the operation is convenient, and the various components of the product 20 can be pressed together quickly and accurately.
