Abstract
The utility model discloses a forklift overhead guard drilling jig which comprises a large-circular-arc shaped right-angle bottom plate. Jig bushes are fastened and mounted on the two right-angle surfaces of the large-circular-arc shaped right-angle bottom plate, wherein the number of the jig bushes is the same as the number of mounting holes on the two right-angle surfaces of a forklift overhead guard; the large circular arc of the right-angle bottom plate is the same as the large circular arc of the forklift overhead guard; the allowance of the center distance of the jig bushes is not more than one third of the allowance of the pitch of holes of the product; the allowance of the verticality of the axes of the jig bushes of the two right-angle surfaces is not more than one second of the allowance of the verticality of the center lines of the holes of the product; and the surface hardness of the jib bushes is HRc55-HRc58. The forklift overhead guard drilling jig can guarantee the technical requirements of the allowance of the pitch of mounting holes of the forklift overhead guard and the verticality of the center lines of holes of the two right-angle surfaces and improves the production efficiency by more than two times.
Description
Technical field
The utility model relates to the clamping tool for machine work field, relates in particular to a kind of fork truck overhead guard drill jig.
Background technology
The fork truck overhead guard is the member that is bent to the great circle arc by square tube, on its two right angle faces, bores a plurality of installing holes of system, pitch-row franchise respectively
± 0.05mm, the center line perpendicularity franchise in hole is 0.1mm on two right angle faces.Prior art is to adopt line, play foreign punching, the method for holing one by one again, and so not only production efficiency is low, and is difficult to guarantee the specification requirement of the center line perpendicularity franchise in hole on pitch-row franchise and two the right angle faces.
Summary of the invention
For addressing the above problem; The utility model provides a kind of fork truck overhead guard drill jig; Utilize this drill jig to bore a plurality of installing holes on system fork truck overhead guard two right angle faces, guaranteeing the perpendicularity franchise requirement of centerline hole on pitch-row franchise and two the right angle faces, and enhance productivity.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of fork truck overhead guard of the utility model drill jig; Comprise great circle arc right angle base plate; The drill bushing that respectively quantity of installing hole equates on fastening installation and the fork truck overhead guard two right angle faces on the described great circle arc right angle base plate two right angle faces, its orthodrome is consistent with fork truck overhead guard orthodrome.
The further improvement of the utility model is: the centre-to-centre spacing franchise between the said drill bushing is not more than 1/3rd of pitch-row franchise on the product; The perpendicularity of drill bushing axis is not more than 1/2nd of centerline hole perpendicularity franchise on the product on the two right angle faces, and the case hardness of drill bushing is HRc55 ~ HRc58.
When boring system fork truck overhead guard two right angle face installing holes,, be that guiding is bored and made each installing hole with the drill bushing as long as after product and drill jig location clamped.
The beneficial effect of the utility model is: can guarantee that installing hole is apart from the pitch-row franchise on the fork truck overhead guard
± 0.05mmWith the perpendicularity franchise of installing hole center line on two right angle faces be the specification requirement of 0.1mm, and enhance productivity more than two times.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is A-A cutaway view.
The specific embodiment
In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is further described below, this embodiment only is used to explain the utility model, does not constitute the qualification of the utility model protection domain.
As depicted in figs. 1 and 2: a kind of fork truck overhead guard drill jig of the utility model comprises great circle arc right angle base plate 1; The drill bushing 2 that respectively quantity of installing hole equates on fastening installation and the fork truck overhead guard two right angle faces on 1 liang of right angle face of described great circle arc right angle base plate, its orthodrome is consistent with fork truck overhead guard orthodrome.The perpendicularity that centre-to-centre spacing franchise between the said drill bushing 2 is not more than drill bushing 2 axis on 1/3rd, the two right angle faces of pitch-row franchise on the product is not more than 1/2nd of centerline hole perpendicularity franchise on the product, and the case hardness of drill bushing 2 is HRc55 ~ HRc58.When boring system fork truck overhead guard two right angle face installing holes, as long as after product and great circle arc right angle base plate 1 location clamped, serve as that the guiding brill is made each installing hole with drill bushing 2.
The utility model can guarantee that installing hole is apart from franchise on the fork truck overhead guard after implementing
± 0.05mmWith the perpendicularity franchise of installing hole center line on two right angle faces be the specification requirement of 0.1mm, and enhance productivity more than two times.
