The present application is described in detail below with reference to the figures and alternative embodiments.

As shown in fig. 1, as an embodiment of the present application, a press-fitting apparatus for a key is disclosed, the key including a key assembly 1200 and a decoration 1300, the press-fitting apparatus including a base plate 100, a positioning block 200 mounted on the base plate 100, a side pressing member 300 mounted on the base plate 100, a fixing member 400 disposed opposite to the base plate 100, and a pressing block 500 having one end connected to the fixing member 400.

The positioning block 200 is used for placing a key assembly 1200 to be pressed and the positioning block 200 of the decorating part 1300; the side pressing assembly 300 transversely presses the key assembly 1200 and the decoration 1300 which are placed on the positioning block 200; the fixing member 400 is movable toward the bottom plate 100; the pressing block 500 is opposite to the position, used for placing the key assembly 1200 to be pressed, on the positioning block 200; the key assembly 1200 and the decoration 1300, which are placed on the positioning block 200, are vertically pre-pressed, and the key assembly 1200 and the decoration 1300 are press-fitted to each other.

After being stressed, the fixing assembly 400 moves towards the direction close to the bottom plate 100 and drives the pressing block 500 to be vertically pre-pressed, the key assembly 1200 and the decorating part 1300 are pressed and mounted mutually, and the side pressing assembly 300 carries out transverse pressing and mounting on the key assembly 1200 and the decorating part 1300.

At present, the automobile key assembly process on the production line adopts a manual press-fitting mode, and wastes time and labor. Meanwhile, the buckles are not easy to press and mount, time and labor are consumed during batch reworking and operation, and the next procedure is influenced.

The applicant combines the above problems, and analyzes the key assembling process, so that the press-fitting device for the key is invented, only the key assembly 1200 and the decorating part 1300 need to be placed into the positioning block 200, the fixing component 400 moves towards the direction close to the bottom plate 100 after being stressed, the pressing block 500 is driven to vertically pre-press, the key assembly 1200 and the decorating part 1300 are mutually press-fitted, the side pressure component 300 carries out transverse press-fitting on the key assembly 1200 and the decorating part 1300, and therefore the press-fitting is in place, the assembled key can be taken out, time and labor are saved, high stability and high efficiency are achieved, and meanwhile, the yield of part assembling is increased.

The side pressure assembly 300 may have the following specific structure: the side pressure assembly 300 comprises a fixed block 310 and a sliding block 320; the fixing block 310 is fixed on the base plate 100 and is located at the right side of the positioning block 200; the sliding block 320 is disposed on the fixing block 310 and can slide in a direction away from and close to the positioning block 200; the slider 320 is slid to laterally press-fit the key assembly 1200 and the garnish 1300. The right side of the positioning block 200 is illustrated here as the right side of fig. 1.

The press-fitting device further comprises a wedge 600, one end of the wedge 600 is fixed on the fixing component 400, and the other end of the wedge is provided with an inclined surface; correspondingly, an inclined surface which is inclined with the inclined surface of the wedge 600 is arranged at one end of the sliding block 320 far away from the positioning block 200. After the fixing assembly 400 is stressed, the fixing assembly moves towards the direction close to the bottom plate 100 and drives the wedge 600 to move downwards, the wedge 600 is matched with the inclined surface of the wedge 600 through the inclined surface of the wedge 600, the sliding block 320 is pushed to move towards the direction close to the positioning block 200, and the key assembly 1200 and the decoration 1300 are pressed and mounted transversely. The fixing assembly 400 can drive the wedge 600 to move downwards while moving downwards to drive the pressing block 500, so that the sliding block 320 is displaced, and two purposes are achieved at one time; meanwhile, the sliding block 320 and the pressing block 500 synchronously act on the key assembly 1200 and the decorating part 1300, so that the press-fitting stability is ensured, and the press-fitting efficiency is improved.

The fixing assembly 400 specifically includes a cover plate 410, a pressure plate 420, and a fixing plate 430; the pressing plate 420 is disposed between the cover plate 410 and the fixing plate 430, the cover plate 410 is located on one side of the pressing plate 420 far away from the positioning block 200, the fixing plate 430 is located on one side of the pressing plate 420 close to the positioning block 200, the pressing plate 420 is fixed on the cover plate 410, and the fixing plate 430 is fixed on the pressing plate 420. The top of the cover plate 410 is further provided with a mold handle 900 for an assembler to push the fixing assembly 400, and the press-fitting device is manually driven. Of course, a power system can be designed correspondingly, and the press-fitting device can be driven to work by a motor and the like.

As shown in fig. 2 and 3, an end of the pressing block 500 away from the fixing element 400 is arc-shaped and is consistent with the surface shapes of the key assembly 1200 and the decoration 1300, so that the pressing block 500 can pre-press and press-fit the key assembly 1200 and the decoration 1300 better. Of course, the shape of the end of the pressing block 500 away from the fixing element 400 can also be adjusted and matched according to the surface shapes of the key assembly 1200 and the decoration 1300.

Specifically, the height of one end of the pressing block 500 away from the fixing element 400, which is close to the fixing block 310, is smaller than the height of one end of the pressing block 500, which is away from the fixing element 310, so that after the pressing block 500 presses the key assembly 1200 and the decoration 1300, one sides of the key assembly 1200 and the decoration 1300, which are close to the fixing block 310, are exposed and not covered by the pressing block 500, and the sliding block 320 is convenient to press the key assembly 1200 and the decoration 1300 at the positions. Of course, the slider 320 may press the key assembly 1200 and the garnish 1300 in other ways or at other locations.

As shown in fig. 4, a guide plate 700 is disposed on the bottom plate 100, a guide plate groove 210 is disposed at the bottom of the positioning block 200, the guide plate 700 is fitted in the guide plate groove 210 of the positioning block 200, and a handle 220 for pushing and pulling is disposed on the positioning block 200; the positioning block 200 is slidable on the guide plate 700 by a push-pull handle 220, and is offset from the pressing block 500. An assembler can pull the positioning block 200 away from the working area corresponding to the pressing block 500, then place the key assembly 1200 and the decoration 1300 on the positioning block 200, and then push the positioning block 200 into the working area corresponding to the pressing block 500 to perform press-fitting operation, thereby ensuring the safety of the assembler.

Specifically, the cross-sectional shape of the guide plate 700 is a T-shape, and correspondingly, the shape of the guide plate groove 210 is matched with the shape of the guide plate 700. The fit between the guide plate 700 and the guide plate groove 210 prevents the positioning block 200 from falling off.

Correspondingly, as shown in fig. 5, the press-fitting device further includes a limiting column 1000 for limiting the positioning block 200, and the limiting column 1000 is fixedly installed on the bottom plate 100 and is located at the opposite side of the handle 220. The limiting column 1000 can limit the positioning block 200, and prevent the positioning block 200 from being pushed over the head when being pushed back to the working area corresponding to the pressing block 500.

As shown in fig. 6, a first accommodating cavity 421 is formed in the pressing plate 420, and one end of the pressing block 500 passes through the fixing plate 430 and is clamped in the first accommodating cavity 421, and can vertically move in the first accommodating cavity 421; one end of the pressing block 500 close to the cover plate 410 is provided with a second accommodating cavity 510 with an opening, a spring 800 is arranged in the second accommodating cavity 510, one end of the spring 800 in the second accommodating cavity 510 abuts against the bottom of the second accommodating cavity 510, and the other end of the spring abuts against the cover plate 410 and is always in a compressed state. The spring 800 in the second accommodating cavity 510 can enable the pressing block 500 to have a pre-pressing function, and specifically, before the pressing block is in contact with the key assembly 1200 and the decoration 1300, one end of the pressing block 500 in the second accommodating cavity 510 is pressed against the lowest position in the second accommodating cavity 510 under the elastic force of the spring 800; when contacting the key assembly 1200 and the decoration 1300, the pressing piece 500 is pressed, and an end of the pressing piece 500 in the second accommodation chamber 510 is moved upward accordingly, and compresses the spring 800 until reaching the highest position in the second accommodation chamber 510. In this process, the elastic force generated by the spring 800 acts against the pressing block 500, so that the pressing block 500 can pre-press the key assembly 1200 and the decoration 1300, thereby realizing the initial positioning and press-fitting, and facilitating the final press-fitting of the pressing block 500 and the side pressure assembly 300.

Specifically, the pressing block 500 is clamped in the first accommodating cavity 421, and protrusions 520 are disposed on two sides of an end portion of the pressing block 500 close to one end of the cover plate 410, and the protrusions 520 are clamped with the fixing plate 430, so that the pressing block 500 is ensured to be vertically movable in the first accommodating cavity 421 and not to be separated from the first accommodating cavity 421.

As shown in fig. 7, the fixing block 310 is provided with a sliding groove 311, and the slider 320 is inserted into the sliding groove 311 and can slide in the sliding groove 311 in a direction away from and close to the positioning block 200. A third accommodating cavity 312 extending along the sliding direction of the slider 320 is arranged in the sliding groove 311, and a spring 800 is arranged in the second accommodating cavity 510; the slider 320 is provided with a column 321 extending towards the bottom plate 100, and the main body is inserted into the third accommodating cavity 312; the spring 800 in the third receiving cavity 312 is disposed between one end of the third receiving cavity 312 near the positioning block 200 and the cylinder 321. When the slider 320 is pushed by the wedge 600 to move in a direction approaching the positioning block 200, the cylinder 321 compresses the spring 800 in the third accommodating cavity 312, and after the wedge 600 is separated from the slider 320, the compressed spring 800 in the third accommodating cavity 312 expands and pushes the slider 320 to return through the cylinder 321. Such an arrangement may enable automatic resetting of the movement of the slider 320 entirely by mechanical means. In combination with the above scheme, the following advantages are achieved: an assembler only needs to push the fixing assembly 400 to complete all press fitting actions of the press fitting device, including pre-pressing, press fitting of the press block 500, resetting of the press block 500, press fitting of the slide block 320 and resetting of the slide block 320, so that multiple purposes are achieved, and the press fitting efficiency is high.

Specifically, one end of the third accommodating cavity 312 close to the positioning block 200 is open; the press-fitting device further comprises a stopper 1100, wherein the stopper 1100 is fixed on one side of the fixing block 310 close to the positioning block 200 and seals the opening of the third accommodating cavity 312; after the spring 800 in the third receiving cavity 312 is compressed, one end of the spring abuts against the stopper 1100, and the other end of the spring abuts against the post 321. The stopper 1100 may be fixed to the fixing block 310 by a screw, so that the spring 800 in the third receiving cavity 312 may be replaced conveniently.
