As shown in fig. 1 to 3, in the aluminum alloy section circular arc groove tapping deviation prevention device, tapping is performed on a section 1 through a tapping component 3, the section 1 is provided with a tapping hole 11 for tapping, a part of the side wall of the tapping hole 11 penetrates through a notch 111 formed along the extending direction of the tapping hole 11, a limiting hole is formed on a tapping deviation prevention device 2, the tapping deviation prevention device 2 can be inserted and fixed to the section 1 along the extending direction of the tapping hole 11 to cover the side wall of the tapping hole 11, the tapping component 3 penetrates through the limiting hole and extends into the tapping hole 11 to perform tapping, and the tapping deviation prevention device 2 can limit the deformation of the tapping hole 11 at the notch 111; the tapping deviation-proof device 2 is matched with the structure of the section bar 1, when the tapping deviation-proof device 2 is inserted into the corresponding section bar 1, the tapping deviation-preventing device 2 is fixed with the section bar 1, the relative movement between the tapping deviation-preventing device 2 and the section bar 1 is prevented, the tapping effect is better, and in the tapping process, when the tapping component 3 expands outwards along the position of the notch 111, the side wall of the tapping hole 11 is driven to deform outwards at the same time, the tapping deviation preventing device 2 can cover the side wall of the tapping hole 11 when being fixed to the section bar 1, so that the deformation of the side wall of the tapped hole 11 is blocked by the deviation preventing device 2, thereby limiting the deformation of the tapped hole 11, and then carry on spacingly through tapping hole 11 to tapping subassembly 3, make tapping subassembly 3 only can remove along the extending direction of tapping hole 11 and carry out the tapping to improve the accuracy of the screw thread that forms after the tapping.
It can be understood, aluminium alloy ex-trusions that point out in this application once only carries out big batch processing through the mould man-hour, and the aluminium alloy ex-trusions structure of processing out is unanimous, therefore, only need prevent inclined to one side device 2 alright through a tapping and prevent inclined to one side processing when carrying out the tapping to the aluminium alloy ex-trusions of same batch processing out, consequently, the structure of the aluminium alloy ex-trusions of processing out is different, corresponding tapping prevents inclined to one side device 2 and also can change, of course, because aluminium alloy ex-trusions are mass production when processing man-hour, consequently to the section bar 1 of different shapes and then process out the mould of mating structure, when improving the stability of tapping, because tapping prevents inclined to one side device 2 and can process the aluminium alloy ex-trusions of same batch, can not cause the tapping to prevent inclined to one side device 2's waste yet.
And the tapping subassembly 3 in this application then can select to be present the screw tap that is used for processing the internal thread, processes out the internal thread with certain moment of torsion with the screw tap screw in the tapping hole 11 that will bore, and the model of screw tap then can be selected according to the size of the internal thread that section bar 1 needs processed simultaneously, and it is no longer repeated here.
In order to enable the tapping deviation-preventing device 2 to limit the deviation of the tapping assembly 3, the hardness of the tapping deviation-preventing device 2 is greater than that of the tapping assembly 3; because tapping subassembly 3 need stretch into 11 departments of tapping hole through the spacing hole in tapping subassembly 3 when the tapping, hardness when making tapping anti-deviation device 2 is greater than tapping subassembly 3's hardness, can enough prevent that tapping subassembly 3 from destroying the structure with spacing hole when the tapping, lead to spacing hole size increase to lose spacing effect, and simultaneously, when tapping subassembly 3 is skew in tapping hole 11, tapping anti-deviation device 2 also can not take place deformation because the extrusion when blockking tapping subassembly 3, thereby guarantee spacing reliability.
When the tapping is prevented partially putting 2 when pegging graft to section bar 1 department, the axis of the spacing hole in the tapping is prevented partially putting 2 and the axis coincidence of tapping hole 11 in section bar 1, can ensure like this that tapping subassembly 3 can not take place the skew when pegging graft to tapping hole 11 through spacing hole, simultaneously when tapping subassembly 3 outwards removes in tapping hole 11, tapping is prevented partially putting 2 not only can prevent 11 deformations of tapping hole through the part with 11 lateral wall contacts of tapping hole, also can carry out the butt with the inner wall in spacing hole when tapping subassembly 3 takes place to remove simultaneously, can carry out spacingly to tapping subassembly 3 through the inner wall in spacing hole, drive 11 deformations in tapping hole after preventing 3 skews of tapping subassembly.
Preferably, the inner wall of the limiting hole and the inner wall of the tapping hole 11 are positioned in the same plane in the state that the tapping deviation preventing device 2 is inserted into the section bar 1; the inner diameter of the limiting hole is equal to that of the tapping hole 11, because the tapping deviation-preventing device 2 is matched with the section bar 1 for production and use, when the tapping deviation-preventing device 2 is inserted into the section bar 1, not only can the accurate installation of the tapping deviation-preventing device 2 and the section bar 1 be realized through the matching of the limiting hole and the tapping hole 11, but also the height of the tapping hole 11 is indirectly prolonged through the limiting hole, when the tapping component 3 is inserted into the tapping hole 11, the tapping component 3 can be abutted against the inner wall of the limiting block, the tapping component 3 can be limited through the contact part of the tapping deviation-preventing device 2 and the side wall of the tapping hole 11, the deformation of the tapping hole 11 is prevented, meanwhile, the tapping component 3 can be limited through the limiting hole, the limiting effect of the tapping component 3 is better, and the hardness of the tapping deviation-preventing device 2 is greater than that of the tapping component 3, therefore, even if the tapping deviation-preventing device 2 is in contact with the tapping component 3, the structural integrity of the tapping deviation preventing device 2 can be ensured; it can be understood that, when tapping the tapping hole 11 by the tapping component 3, the tapping component 3 extends into the tapping hole 11 by passing through the limiting hole, and therefore, the tapping component 3 has a portion located in the limiting hole and a portion located in the tapping hole 11, and therefore, the portion of the tapping component 3 in contact with the limiting hole is different from the portion of the tapping component 3 in contact with the tapping hole 11, and when the tapping component 3 extends into the limiting hole gradually, although the portion of the tapping component 3 in contact with the limiting hole changes gradually, the tapping component 3 taps in the tapping hole 11 at the beginning of the portion passing through the limiting hole all the time, and therefore, the portion of the tapping component 3 located in the limiting hole during tapping is worn due to contact with the inner wall of the limiting hole, and the tapping of the tapping component 3 to the tapping hole 11 is not affected.
As shown in fig. 1, the tapping deviation prevention device 2 includes a limit plate 21 inserted into the profile 1 and a fixing plate 22 connected to the limit plate 21, and the fixing plate 22 can abut against the end face of the profile 1; tapping deviation preventing device 2 is pegging graft to section bar 1 back, realizes the cladding of 11 lateral walls of tapping hole through limiting plate 21, and after the grafting finishes, carries out the butt through the terminal surface of fixed plate 22 with section bar 1, thereby restriction limiting plate 21 continues to stretch into in section bar 1, thereby guarantee limiting plate 21 and 11 terminal surface parallel and level of tapping hole, just can restrict tapping subassembly 3 through limiting plate 21 when tapping subassembly 3 stretches into in the tapping hole 11, prevent that tapping subassembly 3 from driving 11 deformations of tapping hole.
Preferably, the limiting plate 21 is made of high-strength steel since the limiting plate 21 contacts with the side wall of the tapping hole 11, and the hardness of the material of the limiting plate 21 is greater than that of the tapping assembly 3.
The limiting plate 21 and the fixing plate 22 can be designed to be integrally formed, so that the stability of the joint of the limiting plate 21 and the fixing plate 22 is improved; it can be understood that, tapping anti-deviation device 2 passes through limiting plate 21 and the contact of tapping hole 11, and consequently, limiting plate 21 need carry on spacingly to tapping hole 11, prevents that tapping unit 3 from taking place the skew when the tapping, and consequently limiting plate 21's wearing and tearing speed will be faster than fixed plate 22's wearing and tearing speed, consequently, can be with the preferred components of a whole that can function independently design that carries on of limiting plate 21 and fixed plate 22, can change the great limiting plate 21 of degree of wear at any time to realize tapping anti-deviation device 2's cyclic utilization.
The fixing plate 22 is formed with a threaded hole 221, and the tapping deviation prevention device 2 further includes a bolt 23 connected to the limit plate 21 through the threaded hole 221; the threaded connection is a detachable fixed connection, has the advantages of simple structure, reliable connection and convenient assembly and disassembly, and is widely applied to machinery; for convenience of forming the threaded hole 221 in the fixing plate 22, the fixing plate 22 is made of stainless steel, so that the hardness of the fixing plate 22 is smaller than that of the limiting plate 21.
Preferably, the projection of the profile 1 along the extension direction of the tapping hole 11 falls into the fixing plate 22; fixing plate 22 is greater than section bar 1 at radial ascending size, therefore tapping stop device is when pegging graft to section bar 1 department, and section bar 1's terminal surface just can the butt in fixing plate 22 department, can enough carry on spacingly to limiting plate 21 through fixing plate 22, when carrying out the tapping to section bar 1, also can not produce between fixing plate 22 and the section bar 1 and rock simultaneously to prevent that tapping subassembly 3 from taking place the skew, stability when ensureing the tapping.
The section bar 1 is sunken to form a clamping groove 12, the clamping groove 12 is communicated with the tapping hole 11 through a notch 111, and the tapping deviation preventing device 2 is inserted into the clamping groove 12 and is abutted against the inner wall of the clamping groove 12; the clamping groove 12 is formed when the section bar 1 is processed, not only can be inserted by the tapping deviation-preventing device 2, but also can be fixed and decorated when the section bar 1 is used, wherein, because part of the side wall of the tapping hole 11 penetrates through the opening 111, the opening 111 is communicated with the clamping groove 12, namely, the clamping groove 12 is communicated with the tapping hole 11 through the opening 111, when the tapping component 3 taps the tapping hole 11, the side wall of the tapping hole 11 is not provided with a limiting structure, the situation that the tapping component 3 moves outwards can occur, by inserting the tapping deviation-preventing device 2 into the clamping groove 12 and abutting against the inner wall of the clamping groove 12, the part of the tapping deviation-preventing device 2 inserted into the clamping groove 12 is matched with the structure of the clamping groove 12, so that the part of the section bar 1 forming the clamping groove 12 is changed into a solid structure, the overall strength can be improved, and the section bar 1 can not deform when tapping the tapping hole 11, simultaneously, the tapping prevents inclined to one side device 2 and the inner wall butt in joint groove 12, also can prevent that the condition of tapping subassembly 3 outside removal from appearing.
It can be understood that, tapping is prevented partially device 2 when pegging graft to section bar 1 department, even section bar 1 is in the region that forms tapping hole 11, section bar 1 also has the structure in the lateral wall department of tapping hole 11 and protects tapping hole 11, but joint groove 12 does not communicate with tapping hole 11 nevertheless because section bar 1 is the aluminium material promptly, and bulk strength is lower, the condition that produces tapping subassembly 3 and move outward equally easily when the tapping, consequently, prevent partially device 2 and the outer structure of tapping hole 11 lateral wall through the tapping and carry out the butt, can realize the tapping stability of subassembly 3 when the tapping equally.
During the joint groove 12 of pegging graft to 1 department of section bar formation of section bar with the tapping anti-deviation device 2, the structure of limiting plate 21 and the structure phase-match of the joint groove 12 of the sunken formation of section bar 1, the outer wall of limiting plate 21 in the anti-deviation device 2 of tapping promptly and the inner wall butt in joint groove 12, through the structure phase-match that makes limiting plate 21 and the sunken joint groove 12 of forming of section bar 1, the tapping is prevented device 2 partially and just can be carried on spacingly by section bar 1 after pegging graft to section bar 1 through limiting plate 21, thereby realize section bar 1 and tapping and prevent fixing of device 2 partially.
In order to improve the connection stability between the tapping deviation preventing device 2 and the section bar 1 when the tapping deviation preventing device 2 is inserted into the section bar 1, a limiting bulge 24 is arranged at the connection position of the tapping deviation preventing device 2 and the outer wall of the tapping hole 11; the outer wall butt of device 2 through spacing arch 24 and tapping hole 11 is prevented partially in the tapping for form interference fit between the outer wall of device 2 and tapping hole 11 is prevented partially in the tapping, thereby the compactness of being connected between device 2 and the 11 outer walls of tapping hole is prevented partially in the reinforcing tapping, and device 2 is prevented partially in the tapping is better to tapping subassembly 3's spacing effect.
Preferably, the limiting protrusion 24 is a hemispherical protrusion arranged on the tapping deviation prevention device 2, and the limiting protrusion 24 has an arc-shaped surface abutted against the outer wall of the tapping hole 11; when the tapping is prevented partially device 2 and is pegged graft to section bar 1 department, the spacing arch 24 of the tapping is prevented partially device 2 department just can with the outer wall sliding contact of tapping hole 11, through setting up spacing arch 24 to the hemisphere arch, the tapping is prevented partially device 2 and can not produce the sense of blocking when sliding, simultaneously, spacing arch 24 is the arcwall face with the part of 11 outer wall contacts of tapping hole, also can avoid fish tail section bar 1, influences section bar 1 quality.
The tapping deviation prevention device 2 comprises a limiting plate 21 inserted into the section bar 1 and a fixing plate 22 connected to the limiting plate 21, and a limiting protrusion 24 is arranged at the limiting plate 21.
Preferably, the number of the limiting protrusions 24 is two, and the two limiting protrusions 24 are oppositely arranged on two sides of the opening 111; because 11 departments of tapping hole are formed with opening 111 for running through the structure, consequently, opening 111's both sides all have 11 structures of tapping hole, move outward when tapping subassembly 3 is when the tapping to lead to 11 outer walls of tapping hole of opening 111 department both sides all outwards to move, through setting up spacing arch 24 into two, can be better carry on spacingly to tapping subassembly 3, thereby guarantee the accuracy of tapping back screw thread.
Preferably, two spacing protrusions 24 are symmetrically arranged about the notch 111, so that the stress on the outer wall of the tapping hole 11 is more balanced, and the tapping effect is better.
Because the notch 111 of the tapping hole 11 is generated due to the limitation of the process, when the tapping deviation preventing device 2 extends into the section bar 1, the tapping deviation preventing device 2 is provided with a compensating piece extending into the notch 111, the structure of the compensating piece is matched with that of the notch 111, and after the tapping deviation preventing device 2 extends into the section bar 1, the compensating piece correspondingly extends into the notch 111, so that the whole outer wall of the tapping hole 11 is kept complete.
It can be understood that although the compensation piece stretches into the tapping hole 11, the compensation piece does not need to be tapped, in order to avoid the compensation piece from influencing the normal tapping of the tapping component 3, the thickness of the compensation piece is smaller than that of the notch 111, therefore, when the tapping deviation preventing device 2 stretches into the profile 1 and then uses the tapping component 3, the tapping component 3 taps the inner wall of the tapping hole 11, but a gap is formed between the tapping component 3 and the compensation piece, therefore, the tapping component 3 is not in contact with the compensation piece, and therefore, the tapping component 3 is prevented from being in contact with the compensation piece.
When adopting above-mentioned tapping to prevent device 2 partially to section bar 1 when the tapping, at first prevent partially device 2 grafting to section bar 1 department with the tapping, because the limiting plate 21 in the device 2 partially is prevented partially to the tapping matches with the joint groove 12 structure in the section bar 1, consequently, the tapping prevents partially device 2 and has just realized the tapping and prevent partially device 2's fixed after grafting to section bar 1, use tapping subassembly 3 to pass the tapping afterwards and prevent that the spacing hole in the device 2 partially stretches into in the spliced eye, realize tapping 11, and at the tapping in-process, when tapping subassembly 3 outwards removes, just can receive the tapping and prevent blockking of device 2 partially to avoid the screw thread skew, tapping attacks partial bad problem.
The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
