Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It should be understood that the description herein of specific embodiments is for purposes of illustration and explanation only and is not intended to limit the invention.
The boring jig for the standard knot of the tower crane according to the utility model is described below with reference to the attached drawings.
As shown in fig. 1 to 3, in an embodiment of the present invention, a boring jig for a standard knot of a tower crane is provided, wherein the boring jig for the standard knot of the tower crane comprises a base frame and a connecting table 20, the base frame comprises a mounting plate 11 and a bottom plate 12 which are arranged in parallel at an interval, and a processing space 13 for boring a male joint 42 is formed between the mounting plate 11 and the bottom plate 12; the connecting table 20 is fixedly installed on the mounting plate 11, a positioning sinking groove 21 for positioning the female connector 43 is formed in the connecting table 20, a positioning hole 22 penetrating through the mounting plate 11 to communicate with the machining space 13 is formed in the bottom of the positioning sinking groove 21, and the positioning hole 22 is suitable for positioning and inserting the male connector 42.
The utility model discloses a connected mode that is used for boring jig of tower machine standard festival and tower machine standard festival divide into two kinds figure 5 and figure 6, is used for processing male joint 42 and female joint 43 on the tower machine standard festival respectively.
As shown in fig. 5, the connecting tables 20 are arranged in a one-to-one correspondence with the main chords 41 on the standard knot of the tower crane, when the male connectors 42 on the main chords 41 are bored, the male connectors 42 on the standard knot of the tower crane need to be inserted into the connecting tables 20 on the mounting plate 11 in a one-to-one correspondence manner, specifically, the male connectors 42 need to penetrate through the positioning holes 22 on the connecting tables 20 and make the parts to be machined extend into the machining space 13, and then, the boring cutters can perform boring machining on the male connectors 42 in the machining space 13. Wherein, because the locating hole 22 is to the location effect of a plurality of male connectors 42 on the standard festival, make male connector 42 can not receive the influence of processing vibrations when the bore hole to this guarantees male connector 42 and main chord 41's stability, has avoided tower machine standard festival's overall structure's deformation.
As shown in fig. 6, a female joint 43 is arranged at one end of the same main chord 41, which is far from the male joint 42, when the female joint 43 on the main chord 41 is bored, the female joints 43 on the tower crane standard sections need to be inserted into the connecting table 20 on the mounting plate 11 in a one-to-one correspondence manner, unlike the male joint 42, the female joints 43 do not need to pass through the positioning holes 22 on the connecting table 20, and only need to be inserted into the positioning sunken grooves 21 in a one-to-one correspondence manner, and at this time, the part of the female joint 43, which needs to be bored, is exposed outside the base frame, so that the boring can be directly performed. Wherein, because the positioning sinking groove 21 is to the location effect of a plurality of female joint 43 on the standard festival, make female joint 43 can not receive the influence of processing vibrations when the bore hole to this guarantees the stability of female joint 43 and main chord 41, has avoided tower machine standard festival's overall structure's deformation.
The utility model discloses a boring jig for tower machine standard festival can be applicable to the bore hole processing of male joint 42 and female joint 43 on the tower machine standard festival, male joint 42 and female joint 43 all can carry out quick accurate position timing and fix through the connection platform 20 on same mounting panel 11, application scope is extensive, and fine stopping the influence of processing vibrations of male joint 42 and female joint 43 when the bore hole to tower machine standard festival, the overall structure's of tower machine standard festival stability has been improved, prevent to produce and warp, fine control the unfitness of butt joint that produces when follow-up male joint 42 and female joint 43 dock, product quality has been guaranteed, reduce the repair cost because of the great production of unfitness of butt joint.
The misalignment is actually the coaxiality of the outer circles of the male joint 42 and the female joint 43 after butt joint, as shown in fig. 4, after the boring process of the male joint 42 and the female joint 43 is completed, the male joint 42 and the female joint 43 can be in butt joint, and the male joint hole 421 on the male joint 42 is matched with the female joint hole 431 on the female joint 43. In the above description, the boring of the male connector 42 refers to the boring of the male connector hole 421 on the male connector 42 by the boring tool; the boring of the female connector 43 means that the female connector hole 431 is formed in the female connector 43 by a boring tool.
The embodiment of the utility model provides an in, because the rectangle structure that general tower machine standard festival encloses for four main chord 41, so will the utility model provides a mounting panel 11 and bottom plate 12 set up to interval parallel arrangement's rectangle flat board, and four bights of rectangular shape's bed frame all are equipped with connection platform 20, and four main chord 41 one-to-ones on connection platform 20 and the tower machine standard festival of four bights are connected.
