Abstract

The invention relates to a positioning dispensing gun which comprises a dispensing gun pipe, a sliding rail, a positioning rod, a single-row radial ball bearing and a thumb screw, wherein the sliding rail is vertically welded on the dispensing gun pipe; the positioning rod and the dispensing gun pipe are arranged in parallel, the lower end of the positioning rod is sleeved in the sliding rail, and the upper end of the positioning rod is higher than the pipe mouth of the dispensing gun pipe; the single-row radial ball bearing is sleeved on the upper end of the positioning rod; and the thumb screw is arranged at the tail of the positioning rod and screwed for fixing the positioning rod on the sliding rail. The section of the sliding rail is concave, and the lower part of the positioning rod is provided with a concave hole and sleeved in the sliding rail. The outer ring of the single-row radial ball bearing is provided with a groove. The positioning rod slides on the sliding rail for regulating the dispensing position, and the single-row radial ball bearing is used for positioning, thus the positioning dispensing gun can adapt to the dispensing on a position with any width, ensures that a dispensing pen is straight and uniform, avoids the lathe glue leakage problem caused by poor dispensing of the glue, reduces the dispensing time and lowers the labor cost.

Description

A kind of location glue spraying gun

Technical field

The invention belongs to automobile face bonding fitting glue envelope field of tool, be specifically related to a kind of novel location glue spraying gun.

Background technology

In the automobile body-in-white production process, each weldment welds together by assembly unit, some position needs waterproof, just necessary compacted sealing, such as the lap-joint of trailing wheel bulge, need to squeeze a fluid sealant that is about 40 centimetres, because the lap-joint on floor has only 1 centimetre with the floor, back, so require fluid sealant to want straight, and can not exceed 1 centimetre scope.But because present glue rifle is a taper gun barrel, gun barrel is smooth straight, no any positioner on the gun barrel head, the workman holds gun barrel the colloid that flows out is coated in above the part, there is not positioner, will cause plastic squeeze not in place, the glue that squeezes on part is inhomogeneous, not straight or intermittent.The workman is slow at plastic squeeze process medium velocity simultaneously, and the plastic squeeze time increases, and has improved cost of labor.Therefore, but need a kind of plastic squeeze of invention position, adapting to the glue spraying gun that on-the-spot plastic squeeze position is changeable and can locate, thereby address the above problem.

Summary of the invention

The purpose of this invention is to provide a kind of novel location glue spraying gun, can regulate plastic squeeze position and location.

A kind of location glue spraying gun comprises plastic squeeze gun barrel, slide rail, backstay, single-row radial ball bearing and major part screw.Slide rail is vertically welded on the plastic squeeze gun barrel; Backstay and plastic squeeze gun barrel be arranged in parallel, and slide rail is inserted in its lower end, and the upper end exceeds the plastic squeeze gun barrel mouth of pipe; Single-row radial ball bearing is enclosed within the backstay upper end; The major part screw is arranged on the backstay afterbody, screws backstay is fixed on the slide rail.The section of slide rail is a concave shape, and the backstay bottom has the concave shape hole, is inserted in the slide rail.Fluted on the outer ring of single-row radial ball bearing.

The present invention is by sliding backstay on slide rail, adjust the plastic squeeze position, and position by single-row radial ball bearing, can adapt to the plastic squeeze of any width position, guarantee that plastic squeeze is straight evenly, avoid the glue car body that the causes not in place situation of leaking, and reduced the plastic squeeze time, reduced cost of labor.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further specified.

Referring to Fig. 1, the location glue spraying gun comprises plastic squeeze gun barrel 1, slide rail 2, backstay 3, single-row radial ball bearing 4 and major part screw 5.Slide rail 2 is vertically welded on the plastic squeeze gun barrel 1; Backstay 3 be arranged in parallel with plastic squeeze gun barrel 1, and slide rail 2 is inserted in its lower end, and the upper end exceeds plastic squeeze gun barrel 1 mouth of pipe; Single-row radial ball bearing cover 4 is in backstay 3 upper ends; Major part screw 5 is arranged on backstay 3 afterbodys, screws backstay 3 is fixed on the slide rail 2.

Referring to Fig. 2, the section of the slide rail 2 of this location glue spraying gun is a concave shape.

Referring to Fig. 3, backstay 3 bottoms of this location glue spraying gun have concave shape hole 6, are inserted in the slide rail 2.

Referring to Fig. 4, on the outer ring of single-row radial ball bearing 4 of this location glue spraying gun fluted 7.

Referring to Fig. 5, when using this location glue spraying gun, the first width that requires according to plastic squeeze is in the position of slide rail 2 adjusted backstays 3, when being transferred to corresponding tram, tighten major part screw 5, make backstay 3 fixing, make the groove 7 of single-row radial ball bearing 4 ride the edge of part 9 then, the gun barrel mouth alignment element of glue spraying gun is needed the position of plastic squeeze, plastic squeeze and at the uniform velocity mobile glue rifle, a uniform adhesive tape 8 is just squeezed above the part 9.After finishing, plastic squeeze carries out subsequent processing again.
