Abstract
The utility model discloses a positioning compressing mechanism of a car welding-loading clamp, which comprises a positioning pin which is connected with a mould board, wherein the positioning pin is provided with a through groove which passes through the axis, and a press block seat with an inner hole, two press blocks making scissor-shaped movement and a press block collecting a extending mechanism are arranged below the positioning pin, and the press block seat inner hole and the through groove of the positioning pin are provided with the space which are free for the two press blocks to pass through. By adopting the structure, the positioning compressing mechanism of the car welding-loading clamp has small occupied space; moreover, when the sheet metal component which is required to be compressed stays in a closed structure, a better compression effect can be played, thereby preventing the deformation of the sheet metal component caused by the force transfer compression, and can improve the welding precision of the white car body.
Description
Technical field
The utility model relates to automobile welding and assembling clamp, relates in particular to the location hold-down mechanism of automobile welding and assembling clamp.
Background technology
Automobile welding and assembling clamp need position and compress sheet metal component, automobile welding and assembling clamp comprises template, the alignment pin that band supports, back-up block, compact heap and briquetting connecting plate, the alignment pin that band supports is fixed on the template, the smooth outer surface sealing of alignment pin, the side of alignment pin has compact heap, alignment pin separates with compact heap, this structure occupation space is bigger, can't be used under the smaller situation of space requirement, particularly the surface of the sheet metal component that will compress is in the structure of sealing, as automobile longitudinal girder, then only with by compressing the part on its top, transmission by power reaches the purpose that compresses lower piece, but automobile metal plate work generally all belongs to sheet member, and rigidity is bad, and is yielding, thisly can cause the distortion of sheet metal component, cause welding precision to reduce by the mode of power transmission.
The utility model content
Technical problem to be solved in the utility model is: the location hold-down mechanism that a kind of automobile welding and assembling clamp is provided, the location hold-down mechanism of this kind automobile welding and assembling clamp not only takes up room little, and can avoid the sheet metal component distortion, can improve the welding precision of automobile body-in-white.
Solve this technical problem, the technical solution of the utility model is: a kind of location hold-down mechanism of automobile welding and assembling clamp, comprise the alignment pin that is connected with template, described alignment pin is provided with the through slot by axis, alignment pin below is provided with briquetting seat with endoporus, cut two briquettings of shape motion and briquetting draws in and stretches part, and described briquetting seat endoporus and alignment pin through slot have described two freely through spaces of briquetting.
Described briquetting draws in and stretches part and comprise that the piston rod of pneumatic cylinder, pneumatic cylinder top and piston rod upper vertical are in the bearing pin of piston rod axis, described bearing pin passes the extension, bottom of two briquettings, and the bearing pin top of described briquetting seat endoporus is provided with the fastener that draws two briquettings in.
The location hold-down mechanism of the utility model automobile welding and assembling clamp adopts such structure, it is little to take up room, and be in when the sheet metal component that will compress in the structure of sealing and can also well play pressuring action, avoided compressing the sheet metal component distortion that causes, can improve the welding precision of automobile body-in-white by the power transmission.

In Fig. 1, Fig. 2, Fig. 3,1, the angle seat; 2, template; 3, first briquetting; 4, second briquetting; 5, regulation piece; 6, sheet metal component A; 7, regulation piece; 8, sheet metal component B; 9, alignment pin; 10, briquetting seat; 11, briquetting draws in and stretches part; 12, bearing pin; 13, pneumatic cylinder; 14, connecting rod; 15, pad.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, automobile welding and assembling clamp comprises angle seat 1, template 2 regulation pieces 5,7 and the location hold-down mechanism, the location hold-down mechanism comprises alignment pin 9, first briquetting 3, second briquetting 4, briquetting seat 10 and briquetting draw in and stretch part 11, alignment pin 9 is connected with template, alignment pin 9 has the through slot by axis, briquetting seat 10 is positioned at alignment pin 9 belows, place pad 7 between alignment pin and the briquetting seat 10, briquetting seat 10 has endoporus, have first briquetting 3 and second briquetting, 4 freely through spaces in the briquetting seat endoporus, first briquetting 3 and second briquetting 4 stretch out the through slot of alignment pin 9 under impaction state, first briquetting 3 and second briquetting 4 can be cut the shape motion.Briquetting draw in to stretch part 11 and comprises that the connecting rod 14 of pneumatic cylinder 13, pneumatic cylinder 13 tops and connecting rod 14 upper vertical are in the bearing pin 12 of connecting rod axis, described bearing pin 12 passes the extension, bottom of first briquetting 3 and second briquetting 4, and bearing pin 12 tops of briquetting seat endoporus have the fastener that draws briquetting in.
When sheet metal component A6 and sheet metal component B8 are placed on the automobile welding and assembling clamp, sheet metal component A6 and sheet metal component B8 sealing, sheet metal component B8 is by alignment pin 9 location, first briquetting 3 and second briquetting 4 stretch out alignment pin 9, when the piston rod of pneumatic cylinder moves downward, drive first briquetting 3 and second briquetting 4 moves downward, sheet metal component B8 pushing down tightly; After welding finishes, the piston rod of pneumatic cylinder moves upward, and it is pushing away first briquetting 3 and second briquetting 4 moves upward, and first briquetting 3 and second briquetting 4 are cut the shape motion and inwardly closed up, first briquetting 3 and second briquetting 4 fall back in the alignment pin 9, so that sheet metal component takes out.The location hold-down mechanism of the utility model automobile welding and assembling clamp adopts such structure, it is little to take up room, and be in when the sheet metal component that will compress in the structure of sealing and can also well play pressuring action, avoided compressing the sheet metal component distortion that causes, can improve the welding precision of automobile body-in-white by the power transmission.
