Abstract
The invention discloses a drilling jig for an overhead guard of a forklift truck, which comprises a large circular arc right-angled base plate, wherein drill bushings with the same amount of mounting holes on two right-angled surfaces of the overhead guard of the forklift truck are respectively fastened and mounted on two right-angled surfaces of the large circular arc right-angled base plate; and a large circular arc of the large circular arc right-angled base plate is consistent with that of the overhead guard of the forklift truck. The tolerance of center distance between every two drill bushings is not more than one third of the tolerance of the hole pitch of a product; the verticality of the axes of the drill bushings on the two right-angled surfaces is not more than one second of the tolerance of the verticality of a center line of a hole on the product; and the surface hardness of each drill bushing is HRc55-HRc58. According to the drilling jig disclosed by the invention, the technical requirements of the tolerance of the hole pitch between every two mounting holes on the overhead guard of the forklift truck and the tolerance of the verticality of the center lines of the holes on the two right-angled surfaces can be ensured and the production efficiency is improved by more than three times.
Description
Technical field
The present invention relates to the clamping tool for machine work field, relate 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 present invention 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 present invention realizes through following technical scheme:
A kind of fork truck overhead guard of the present invention 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.
Further improvement of the present invention 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 invention has the beneficial effects as follows: 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 a structural representation of the present invention.
Fig. 2 is A-A cutaway view.
The specific embodiment
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is further described below, this embodiment only is used to explain the present invention, does not constitute the qualification of protection domain of the present invention.
As depicted in figs. 1 and 2: a kind of fork truck overhead guard drill jig of the present invention 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 present invention 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.
Claims (2)
1. fork truck overhead guard drill jig; Comprise great circle arc right angle base plate (1); It is characterized in that: 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 described great circle arc right angle base plate (1) the two right angle face, its orthodrome is consistent with fork truck overhead guard orthodrome.
2. a kind of fork truck overhead guard drill jig according to claim 1; It is characterized in that: the centre-to-centre spacing franchise between the said drill bushing (2) is not more than 1/3rd of pitch-row franchise on the product; The perpendicularity of said drill bushing (2) axis is not more than 1/2nd of centerline hole perpendicularity franchise on the product, and the case hardness of said drill bushing (2) is HRc55 ~ HRc58.
