Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, in a fixing device for fixing a plastic part 50 and a metal part 51 in a lamp fitting, the plastic part 50 and the metal part 51 both have abutting surfaces for abutting, attaching and fixing with each other, a convex column 501 is formed on the abutting surface of the plastic part 50, and a through hole for the convex column 501 to be inserted in a matching manner is formed on the abutting surface of the metal part 51; the fixing device comprises a support frame, a positioning unit arranged on the support frame and used for positioning the bottom of the plastic part 50, and a hot melting unit arranged on the support frame and positioned above the positioning unit, wherein the plastic part 50 is positioned in the positioning unit, the metal part 51 is positioned above the plastic part 50, and when the convex column 501 is inserted into the through hole, the hot melting unit can support the upper end part of the convex column 501 to perform hot melting and deform the upper part of the convex column 501. The convex column 501 is hot melted and pressed, so that the upper part of the convex column 501 is heated and deformed, and the convex column 501 deformed at the upper part forms riveting fastening force on the metal piece 51, thereby fixing the metal piece 51 on the plastic piece 50.
Specifically, the support frame includes a support cabinet 10, a first support plate 11 provided on the support cabinet 10, a second support plate 12 located above the first support plate 11, and a support column 13 connected and supported between the first support plate 11 and the second support plate 12. The support assembly 32 is slidably disposed on the support column 13.
Further, the positioning unit includes a positioning plate 20 and a bottom plate 21 fixedly supported at the bottom of the positioning plate 20, a guide rail 22 is disposed on the support frame, a slider 23 is disposed on the guide rail 22 in a sliding manner, and a second driver (not shown in the figure, the bottom plate 21 is fixedly connected with the slider 23 and slides relative to the guide rail 22 through the slider 23) drives the bottom plate 21 to move on the guide rail 22 through the slider 23, and the positioning plate 20 at least has a feeding station for feeding and a hot melting station for receiving hot melting by the convex column 501. The positioning plate 20 is formed with a positioning cavity for positioning the bottom of the plastic part 50. Two groups of positioning cavities are arranged. Two sets of location chambeies then can make when carrying out hot melt work, once only install fixedly to two sets of products, provide the productivity, provide production and work efficiency.
Further, the fuse unit includes a fuse head 30 (formed by a copper rod), a heating plate 31 for heating the fuse head 30, a supporting member 32 for supporting the heating plate 31, and a first driver 33 for driving the supporting member 32 to move up and down to drive the fuse head 30 to move up and down. The thermal fusion heads 30 have two sets, and each set has two thermal fusion heads 30. Every two hot melting heads 30 respectively correspond to two convex columns 501 in one group of positioning cavities, when the hot melting heads are pressed, one group of hot melting heads 30 are pressed against the convex columns 501 in one group of positioning cavities, and the other group of hot melting heads 30 are pressed against the convex columns 501 in the other group of positioning cavities.
In this example, the fixing device also comprises cooling means for cooling the upper deformed stud 501. Hot melt head 30 supports and presses projection 501, make projection 501 be heated after the deformation, to stablizing metalwork 51 on plastic part 50, this moment because the position that projection 501 warp is in the molten condition, namely, hot melt head 30 can not break away from the contact with projection 501 upper portion at once after pressing the deformation with projection 501, otherwise can probably lead to projection 501 to warp the position and be peeled off, lead to the fixed failure of hot melt, produce the defective products, consequently, need cool off projection 501 through cooling body, make projection 501 cool off and stereotype, then can upwards keep away from at hot melt head 30, so just stopped the damage of hot melt face, the qualification rate of product has been improved. The cooling mechanism comprises an air pressure regulating valve 40, an air inlet pipe (not shown in the figure) connected to the air pressure regulating valve 40 and used for communicating the air inlet pipe with an external air generating device, and an air blowing pipe (not shown in the figure) communicated with the air pressure regulating valve 40, wherein the air blowing end of the air blowing pipe extends to a position close to the convex column 501 from the air pressure regulating valve 40. The blowing pipe blows cold air to the convex column 501 and the hot melting head 30 which are deformed by hot melting and abut against the head of the convex column 501, so that the convex column 501 and the head of the hot melting head 30 are rapidly cooled until the convex column 501 is solidified, and then the driver drives the hot melting head 30 to be separated from the convex column 501 upwards, thereby completing hot melting riveting.
To sum up, the utility model discloses a fixing device of plastic part and metalwork in the fixed lamps and lanterns accessory through set up the through-hole on forming projection, metalwork on the plastic part, after in plastic part and metalwork butt joint and projection insert the through-hole, the hot melt unit supports the projection and presses the hot melt, makes the projection deformation to with metalwork fixed mounting on the plastic part, the utility model discloses a fixing device structural design is compact reasonable, and the cost of manufacture is low, can effectively fix the plastic part to make the metalwork can be stable firm install to the plastic part on, when the device used, operation personnel's working strength was low.
