Abstract
The utility model discloses a hand pin positioning mechanism with cylinders. The hand pin positioning mechanism comprises a support frame; a guide sleeve is horizontally disposed on the support frame; a guide shaft capable of sliding back and forth horizontally along the guide sleeve penetrates the guide sleeve; clamping cylinders above the guide sleeve are mounted above the support frame; the extension end of the guide shaft is connected with a pin holder; a positioning shaft slidably connected to the support frame is further mounted at the rear of the pin holder; collision blocks are correspondingly mounted at the rear of the positioning shaft at the front ends of piston rods of the clamping cylinders; at least one positioning pin is mounted on the pin holder; a drive handle driving the pin holder to move forward for positioning is further mounted on the support frame. The hand pin positioning mechanism is simple and compact in structure and very practical and allows small metal sheets to be positioned and supported, vehicle body detection precision is increased, and cost is lowered.
Description
Technical field
The utility model relates to a kind of hand push pin retention mechanisms with cylinder.
Background technology
Ge great automobile factory is in the detection station of automobile body-in-white welding line car load welding region and relevant assembly, the following three kinds of structures of main employing position: use simple alignment pin supporting construction 1., the shortcoming of this structure is: cannot guarantee the spacing of bodywork height direction, can cause measurement result inaccurate; 2. use the structure of alignment pin location, the support of mo(u)ld bottom half piece, pressure arm and mo(u)ld top half piece hand-operated clamping, the shortcoming of this structure is: the position that Metal Sheets for Body-manufacturing is complicated, clamping section bit space is narrow and small is realized and clamped difficulty, or after clamping, cannot open, and complex structure, cost is high; 3. use the structure of alignment pin location, the support of mo(u)ld bottom half piece, pressure arm and mo(u)ld top half piece pneumatic pinch, the shortcoming of the shortcoming of this structure and above-mentioned the 2nd kind of structure is similar, position complicated at Metal Sheets for Body-manufacturing, that clamping section bit space is narrow and small is realized and is clamped difficulty, or cannot open after clamping, and complex structure, cost is high.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure and location and clamps accurately the hand push pin retention mechanisms with cylinder.
For solving the problems of the technologies described above, the hand push pin retention mechanisms with cylinder providing comprises bracing frame, its design feature is: horizontally disposed fairlead is housed on bracing frame, fairlead is coated with the axis of guide sliding along its level front and back, the clamping cylinder that is positioned at fairlead top is also housed on bracing frame, on the external part of the axis of guide, be connected with key seat, the locating shaft being slidably connected on bracing frame is also equipped with at the rear portion of key seat, the piston rod front end of clamping cylinder and the rear portion correspondence of locating shaft are equipped with collision block, key seat is equipped with at least one alignment pin, the driving handle that drives key seat to move ahead and position is also housed on bracing frame.
Hinged seat is equipped with in the bottom of bracing frame, is hinged with the connecting rod of stretching on hinged seat, and connecting rod is provided with the slotted hole of vertical setting, is connected with the drive rod being installed in described slotted hole on described key seat, and the bottom of described driving handle is connected on connecting rod.
On support frame as described above, with the rear portion correspondence of the axis of guide, guide-localization piece is housed.
Adopt after said structure, order about key seat drive alignment pin to position by driving handle, alignment pin, after small-sized metal plate part is navigated on large-scale sheet metal component, carries out accurate positioning compression by clamping cylinder to sheet metal component.This structure has been avoided the common position that the support clamp mechanism with alignment pin is complicated at Metal Sheets for Body-manufacturing, clamping section bit space is narrow and small to realize and has been clamped difficulty, or situation about cannot open after clamping, simultaneously this structure can arrange a plurality of alignment pins, guarantees the spacing of bodywork height, width, length direction.Thereby the utility model is simple in structure, compact, very practical, can realize the positioning supports to little metal plate part, improve vehicle body accuracy of detection, reduced cost.The displacement that realizes accurately alignment pin that arranges to collision block and guide-localization piece, thus clamped condition and open mode guaranteed.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is the structural representation of a kind of most preferred embodiment of the utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the perspective view of Fig. 1.
The specific embodiment
The hand push pin retention mechanisms with cylinder as shown in Figure 1 to Figure 3, for convenience of describing, take Fig. 1 left and right is on paper fore-and-aft direction, direction perpendicular to paper is left and right directions, this hand push pin retention mechanisms with cylinder comprises bracing frame 1, horizontally disposed fairlead 2 is housed on bracing frame 1, fairlead 2 is coated with the axis of guide 3 sliding along its level front and back, the clamping cylinder 4 that is positioned at fairlead 2 tops is also housed on bracing frame 1, on the external part of the axis of guide 3, be connected with key seat 5, the locating shaft 9 being slidably connected on bracing frame 1 is also equipped with at the rear portion of key seat 5, key seat 5 is equipped with at least one alignment pin 6, alignment pin 6 can be designed to the structure shown in figure, the ejector pin structure that is three-dimensional localization also can be set, its concrete structure designs as required, the driving handle 7 that drives key seat 5 to move ahead and position is also housed on bracing frame 1, specifically, hinged seat 10 is equipped with in the bottom of bracing frame 1, on hinged seat 10, be hinged with the connecting rod 11 of stretching, connecting rod 11 is provided with the slotted hole of vertical setting, on described key seat 5, be connected with the drive rod 12 being installed in described slotted hole, the bottom of described driving handle 7 is connected on connecting rod 11, in the present embodiment, the link position of driving handle 7 and connecting rod 11 is positioned at the below of drive rod 12, hinged seat 10 is positioned at the below of driving handle 7.When driving handle 7 drives key seats to move forward, alignment pin is positioned at little sheet metal component on large sheet metal component, then the driving by clamping cylinder 4 clamps it can to realize the clamping work of locating.
As shown in Figures 2 and 3, the piston rod front end of clamping cylinder 4 and the rear portion correspondence of locating shaft 9 are equipped with collision block 8, on support frame as described above 1, with the rear portion correspondence of the axis of guide 3, guide-localization piece 13 are housed.
