Description
Technical field
The present invention relates to cycle frame, especially a kind of four connecting rod vehicle frame manufacture methods.
Background technology
For performance and the comfort level that improves bicycle, the cycle frame design is constantly weeded out the old and bring forth the new, and by former fixed type vehicle frame, has the vehicle frame of shock-absorbing finally, nowadays occurs the vehicle frame of four connecting rods especially.Because the vehicle frame of four connecting rods can make back vent have shock-absorbing, in conjunction with the Shock absorber of front fork, makes the front and back wheel of bicycle that incabloc function be arranged, thereby improves performance and the comfort level of bicycle greatly.Though the cycle frame of four connecting rods has good effect, but at present still relatively more rare on the market, reason is than higher because of the technological requirement of producing four connecting rod vehicle frames, vehicle frame is difficult to reach proofread and correct and is difficult to reach requirement, thereby tend to be difficult to assembling between the feasible vehicle frame of producing and each parts, thereby reduce production efficiency.
Summary of the invention
Technical matters to be solved by this invention provides a kind of four connecting rod vehicle frame manufacture methods, can effectively reduce the problem of the assembling difficulty of bringing after the vehicle frame moulding, thereby enhance productivity.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of four connecting rod vehicle frame manufacture methods, described vehicle frame comprises pipe, following pipe, middle pipe, a pipe, back vent and five-way, described back vent comprises Seat stay and Chain stay, the described pipe of going up is provided with the pipe bearing, pipe bearing during pipe is provided with in described, being provided with leg-of-mutton attaching parts articulates with described pipe bearing, middle pipe bearing and the Seat stay gone up respectively, the described pipe bearing that goes up is connected with described attaching parts by bumper, one end of bumper and last pipe bearing articulate, and the other end and attaching parts articulate; Pipe is gone up and is provided with the back vent bearing in the top of five-way in described, and an end of described Chain stay is articulated on the described back vent bearing, the other end of Chain stay and the pivot joint of Seat stay; The manufacture method step of vehicle frame is as follows:
(1) will go up on request pipe, down pipe, middle pipe, head are managed and the preceding triangle of five-way formation vehicle frame spot-welded together;
(2) draw vehicle frame figure with the vehicle frame same ratio at paper, vehicle frame is placed on the vehicle frame figure compares, check everywhere position and angle, head pipe parallelism, whether upper and lower pipe camber is consistent with drawing;
(3) except the welding bead of five-way junction, the welding bead of other each junctions all needs to weld with downhand welding;
(3) correction that the preceding triangle of vehicle frame is carried out; Centering is managed, is gone up the center height of pipe and a pipe and proofreaies and correct; With the parallelism of the correct pipe of middle wire gauge, and the place-centric line of last pipe and middle pipe welding bearing is done check;
(4) will go up the pipe bearing and spot weld on the pipe, on middle pipe bearing spot weld upper intermediate tube;
(5) will get dot and be welded on the preceding triangle of proofreading and correct good vehicle frame, put the measurement that attached position needs length and position of getting that welds;
(6) welding of bearing; Before the welding of some postwelding, need proofread and correct and check at the squareness in the center of bearing and hole, can weld after qualified;
(7) to last pipe bearing, middle pipe bearing with get the attached downhand welding of carrying out;
(8) all parts of preceding trigonometric sum of welding being finished vehicle frame need be proofreaied and correct once again;
(9) vehicle frame is heat-treated;
(10) preceding triangle and the back vent of vehicle frame are assembled.
As improvement, Seat stay needs to weld before assembling, and its concrete steps are as follows:
1) with the left and right fork leg of Seat stay, the ditch pawl, joint and bridge tube are spot-welded together;
2) need to proofread and correct earlier once before each parts point postwelding welding of Seat stay, prevent the variation of a postwelding;
3) utilize two of fixed mould locking Seat stay to collude pawl, make that the concentricity, squareness and the pawl that collude the pawl assembly opening are wide can not to deform, each parts to Seat stay carry out downhand welding then.
As improvement, after Seat stay has welded, need be to wide correction of line of centers, disc brake and pawl of Seat stay, concrete steps are:
1) Seat stay is fixed on the fork fixed mould;
Whether 2) use fork center check mould inspection center line meets the requirements;
3) with the planeness between two holes of disc brake Correction Die correction disc brake;
4) with the wide Correction Die of pawl with the wide size that is corrected to drawing regulation of pawl.
As improvement, Chain stay needs to weld before assembling, and its concrete steps are as follows:
1) with left and right fork leg, connecting strap and tap points solder together,
2) need to proofread and correct earlier once before the welding of Chain stay point postwelding, prevent the variation of a postwelding; Respectively width, concentricity and the squareness of the line of centers of Chain stay, furcula parallelism, nipple orifice are proofreaied and correct.
As improvement, described Shock absorber comprises sleeve and is located at the interior spring of described sleeve that described sleeve two ends are provided with mounting ear.
The beneficial effect that the present invention compared with prior art brings is:
The present invention proofreaies and correct each parts respectively before each parts of assembling vehicle frame, guarantees that its all angles, size, camber etc. meet the requirements, and just can accurately install when assembling like this, enhances productivity.
