Problems solved by technology

When welding in this way, on the one hand, the stability of freehand fixation is poor, and the alignment accuracy is also very low, which greatly reduces the welding quality; for thin sheet welding, welding bumps, cracks, arc craters, etc. will occur in the actual welding process Defects need to be polished to ensure that the surface of the interior parts is flat and smooth. This requires the use of special welding equipment and grinding equipment in the production process, which increases production costs and also has the risk of wearing interior parts. Product pass rate
On the other hand, if it is fixed by hand, there is a danger of the operator being scalded by the solder during the welding process, and the safety factor is low

Embodiment 1

[0025] Such as Figure 1-3 As shown, the interior trim fixing device includes a pallet 1 and two interior trim brackets 2. Each interior trim bracket 2 corresponds to two pressing devices 3, and the pressing devices 3 are respectively arranged on both sides of the interior trim bracket 2.

[0026] The pressing device 3 includes a base 31, a pressing head 32 and a handle 33. The base 31 is detachably arranged on the pallet 1 by the first bolt 41. The pressing head 32 includes a connecting rod 34, a pressing block 35 and an adapter rod 36. One end of the connecting rod 34 is rotatably mounted on the base 31 via the first pin 51, and a pressing block 35 is mounted on the other end. The connecting rod 34 is provided with a bar-shaped through hole 37. A step 361 is provided on the adapter rod 36. One end of the adapter rod 36 passes through the bar-shaped through hole 37, and the end is provided with a thread. The step 361 abuts against the lower surface of the connecting rod 34...

Embodiment 2

[0031] The difference between this embodiment and the first embodiment lies in the structure of the pressing device 3. Such as figure 2 As shown, the pressing device 3 includes a base 31, a pressing head 32 and a handle 33. The base 31 is detachably arranged on the pallet 1 by the first bolt 41. The pressing head 32 includes a connecting rod 34, a pressing block 35 and an adapter rod 36. One end of the connecting rod 34 is rotatably connected with the handle 33 through the fifth pin shaft 52. A pressing block 35 is installed at the other end. The connecting rod 34 is provided with a bar-shaped through hole 37. A step 361 is provided on the adapter rod 36. One end of the adapter rod 36 passes through the bar-shaped through hole 37, and the end is provided with a thread. The step 361 abuts against the lower surface of the connecting rod 34. A nut 38 is installed at the end of the adapter rod 36. The nut 38 abuts on the upper surface of the connecting rod 34. The connecti...

Abstract

The invention provides an inner decoration piece fixing device which is characterized by comprising a support plate and at least two abutting pressing devices. Each abutting pressing device comprises a base, a press head and a handle, one end of the press head is installed on the base in a rotating mode, and the handle is connected with the press head and is installed on the base in a rotating mode. The handles can drive the press heads to rotate in the identical direction or in the reverse direction to enable the other ends of the press heads to press inner decoration pieces in an abutting mode. The support plate is provided for the inner decoration pieces to be welded, the inner decoration pieces are fixed through the abutting pressing devices and are accurately aligned, welding accuracy and inner decoration piece stability are improved, welding shortcomings in the traditional welding process are overcome, the welding quality is greatly improved, the inner decoration piece welding safety coefficients are improved, and the danger that an operator is scalded by welding materials is removed.

Description

Technical field [0001] The invention relates to a fixing device for interior trim parts, in particular to a fixing device for interior trim parts used for manual welding process. Background technique [0002] Various functional structures, such as connecting structures, need to be provided on the back of the interior trim parts. Usually, the back of the interior trim is provided with raised pillars. Before use, various structures on the back of the interior trim parts need to be spot welded. The traditional spot welding process of interior parts simply places the interior parts to be welded on the workbench, and welds them by fixing them with their bare hands. When welding in this way, on the one hand, the stability of freehand fixing is poor, and the alignment accuracy is also very low, which greatly reduces the welding quality; for sheet welding, welds, cracks, craters, etc. will occur in the actual welding process. Defects, the welding bead needs to be polished to ensure th...
