Technical Field

[0001] The present invention relates to the technical field of machinery for simple assembly of metal parts and injection-molded parts. Specifically, it relates to a device for riveting metal parts in injection-molded parts. Background Art

[0002] Metal parts are usually required to be installed in the positioning holes of injection-molded parts to enhance the strength for connecting / installing with other parts at this place. In the prior art, riveting is usually adopted, that is, the metal parts are directly pressed into the positioning holes of the injection-molded parts by external force.

[0003] Currently, some factories use manual riveting. When riveting, workers need to manually place the metal parts into the positioning holes and then perform riveting; there are also factories that use fully automatic equipment for full-automatic riveting on the production line by the automated equipment. When using manual riveting, the repetitive labor of workers is large and the production efficiency is low; the equipment for fully automatic riveting is expensive, and for parts that are not mass-produced, it is not worth customizing a set of fully automatic riveting equipment for them.

[0010] Further, the feeding mechanism further includes: a feeding plate and a disc sieve. The feeding channel is opened on the feeding plate, and the feeding channel communicates with the discharge port of the disc sieve.

[0011] Furthermore, the number of the feeding channels is 2.

[0012] Furthermore, the riveting mechanism includes a cylinder capable of reciprocating in the Y direction for riveting.

[0013] Furthermore, a discharging block is also installed on the placing platform. The placing platform can move linearly in the X direction to reach the third node and drive the discharging block to move in the Y direction to eject the injection molded part.

[0014] Furthermore, a waist-shaped hole is formed in the discharging block, a cylindrical pin is installed in the waist-shaped hole, and guiding inclined blocks are arranged at both ends of the cylindrical pin.

Detailed implementation manners

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Generally, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0029] Refer to Figure 2 As shown, the present invention provides a device for riveting a metal part in an injection molded part, including: a feeding mechanism for the metal part 1, a storage platform 3 for placing the injection molded part 2, and a riveting mechanism. The feeding mechanism includes: a feeding rod 41 and a blanking block 42. A material pushing groove 411 is formed on the feeding rod 41, a blanking groove 421 is formed on the blanking block 42, and a blanking hole 422 is formed at the bottom of the blanking groove 421. The feeding rod 41 is installed in the blanking groove 421, and the material pushing groove 411 communicates with a feeding channel 431. The material pushing groove 411 and the blanking hole 422 are staggered in the Z direction;

[0030] Further, the storage platform 3 can move linearly along the X direction to reach the first node, align the positioning hole 21 of the injection molded part 2 with the blanking hole 422, and at the same time drive the feeding rod 41 to move along the Z direction to connect the feeding groove 411 with the blanking hole 422. The number of feeding channels 431 is 2. The storage platform 3 can also move linearly along the X direction to reach the second node and align the positioning hole 21 with the riveting mechanism.

[0031] Referring to Figure 1 , Figure 3 and Figure 4 As shown, the feeding mechanism further includes: a feeding plate 43 and a disk sieve 44. The feeding channel 431 is opened on the feeding plate 43, and the feeding channel 431 communicates with the discharge port of the disk sieve 44. The disk sieve 44 neatly and continuously feeds the metal parts 1 into the feeding channel 431.

[0032] A slider 412 is installed on the feeding rod 41, and the slider 412 is embedded in the chute on the storage platform 3. The chute includes a straight groove portion 31 along the X direction and an inclined groove portion 32 in the XZ plane.

[0033] A positioning block 33 is also installed on the storage platform 3. During actual use, the injection molded part 2 is manually placed on the storage platform 3 through the positioning block 33. It should be noted that at this time, the feeding channel 431 is connected to the feeding groove 411, and the slider 412 is in the straight groove portion 31.

[0034] The storage platform 3 moves in the X direction, and at the same time the slider 412 moves along the straight groove portion 31 and slowly enters the inclined groove portion 32, thereby driving the feeding rod 41 to move along the Z direction. When the storage platform 3 moves to the first node, the positioning hole 21 is aligned with the blanking hole 422, the feeding groove 411 is connected to the blanking hole 422, and the metal part 1 in the feeding groove 411 is fed into the blanking hole 422 by the feeding rod 41, and the metal part 1 falls into the positioning hole 21 under its own gravity, completing the automatic feeding of the metal part 1.

[0035] It is easy to understand that in this embodiment, the storage platform 3 can be sleeved on a lead screw and externally connected to a servo motor to control the movement and stop of the storage platform 3 in the X direction. This technology is well-known common sense in this field and will not be elaborated here.

[0036] Referring to Figure 5 As shown, the riveting mechanism in the present invention includes: a cylinder 5 capable of reciprocating along the Y direction for riveting. After the feeding work is completed, the storage platform 3 moves in the reverse direction to the second node, and the slider 412 enters the straight groove portion 31 from the inclined groove portion 32, reconnecting the feeding groove 411 with the feeding channel 431. The positioning hole 21 is aligned with the cylinder 5, and the cylinder 5 is started to rivet the metal part 1 into the positioning hole 21.

[0037] Reference Figure 6 As shown, a discharge block 6 is further installed on the storage platform 3. An elongated hole 61 is formed in the discharge block 6, and a cylindrical pin 62 is installed in the elongated hole 61. Guide inclined blocks 63 are provided at both ends of the cylindrical pin 62. The storage platform 3 moves linearly in the X direction to reach the third node, driving the cylindrical pin 62 to contact the guide inclined block 63. The cylindrical pin 62 moves from the bottom end to the top end of the elongated hole 61, thereby driving the discharge block 6 to move in the Y direction to eject the injection molded part 2, preventing the injection molded part 2 from generating negative pressure with the storage platform 3 during riveting at the second node, and facilitating the manual removal of the injection molded part 2.

[0038] It is easy to understand that after the discharge block ejects, the storage platform 3 needs to move a fixed distance in the direction close to the second node, and the discharge block 6 resets under its own gravity.

[0039] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
