Abstract
The utility model relates to a plate spring tensioning tooling; two ends of a bottom plate are connected with a movable baffle plate by a tensioning bolt, and a boss is arranged on the movable baffle plate, bosses are arranged at the two ends of the bottom plate, and the tensioning bolt penetrates through the bosses. Another boss is also arranged in the middle of the bottom plate and a pin hole for assembly is arranged on the boss, a groove is arranged on the bottom plate, and the groove is used for being matched with the boss on the movable baffle plate. In the plate spring tensioning tooling, external force of the tooling is used for tensioning a plate spring for assembly, and the tooling has a supporting function for the assembly of the plate spring, so as to prevent deformation caused by dead weight; in order to prevent a single plate spring from being dislocated in the assembly of the plate spring, six phi33 mounting holes matched with locating pins 9 are processed into articulating holes in the assembly of the plate spring, the articulating holes are located by the locating pins and are integrated with the tooling through threads, so as to carry out machining after the presetting tension force is achieved, so that the error caused by inconsistent deformation of materials can be avoided and the assembling precision is improved.
Description
Technical field
The utility model relates to leaf spring machined field, particularly a kind of leaf spring tensioning frock.
Background technology
The leaf spring assembling of the leaf spring hydraulic vibration device in the conticaster is as Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and shown in Figure 8, one group of leaf spring assembling is made up of two veneer springs, and it is negative common difference that the centre-to-centre spacing between dowel hole requires, it is plus tolerance that centre-to-centre spacing between the alignment pin of framework upper mounting plate spring assembling requires the hole, so just makes the leaf spring assembling be in tensioning state.For the processing of leaf spring assembling, domestic manufacturing company takes following processing step to meet design requirement more: blank is cold-reduced sheet and thickness of slab requirement overgauge, and along steel plate rolling direction blanking, processing is changeed in the straight back of smoothing behind the blanking; Add man-hour, leaf spring clamps the processing profile in groups, carries out mark, after the pairing boring, assembles, and after connecting with bolt, runs coordinate and join brill, hinge pin hole on boring machine.Because the cutting force in lifting, deadweight and the processing etc. can make the leaf spring distortion, and there is not a secondary correcting process, the illusion that causes the leaf spring group pitch-row negative common difference that processes, thereby can't satisfy the tensioning requirement of design, will cause each the leaf spring group unbalance stress in the vibrating device like this and influence the function and the life-span of vibrating device.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of leaf spring tensioning frock, can reduce mismachining tolerance, particularly because the error that the difference of material self elastic modelling quantity causes.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of leaf spring tensioning frock, and the base plate two ends are connected with sideboard by tensioning bolt, and described sideboard is provided with boss.
Described base plate two ends are provided with boss, and tensioning bolt passes from boss.
Described base plate middle part also is provided with a boss, and boss is provided with the pin-and-hole that is used to assemble.
Also be provided with on the described base plate and be used for the bond structure groove or the boss that cooperate with sideboard.
The bottom of described base plate and at least one side are provided with the datum level that is used to locate.
Also be provided with the pin-and-hole that is used to assemble on the described sideboard.
Also be provided with on the described sideboard and be used for the bond structure boss or the groove that cooperate with base plate.
The above-mentioned frock of a kind of application is carried out the leaf spring method for processing, may further comprise the steps:
1) with leaf spring tensioning frock leveling and localization step on lathe;
2) with the step of leaf spring by alignment pin connection base plate and sideboard;
3) screw the step of tensioning bolt with the moment of designing requirement;
4) by the step of designing requirement with machine tooling pin-and-hole to be processed;
On leaf spring, process the pin-and-hole that adheres to specification by above step.
Described lathe is a numerical control borer.
Even if the on all four material of appearance and size, leaf spring for example, because the difference of microstructure, under the effect of same tensile force, its elastic deformation amount of each material also is different, and the hole that processes under the no tensile force is though size is in the margin of tolerance, but the back is installed because the difference of deflection, will unbalance stress occurs and influence the function of vibrating device and the problem in life-span.
A kind of leaf spring tensioning frock that the utility model provides, assemble the tensioning apparatus and the corresponding processing method of pin hole processing for the key components and parts leaf spring that is used for conticaster visual plant leaf spring hydraulic vibration device, utilize frock external force to come the assembling of tensioning leaf spring, also assembling plays supporting role to frock to leaf spring simultaneously, prevented its distortion that produces because of deadweight, for making the pretty good position of monolithic leaf spring in the leaf spring assembling, to be treated to articulation hole on 6 φ 33 and the installing hole technology that alignment pin 9 cooperates in the leaf spring assembling, be connected as a single entity with the alignment pin location and by screw thread and frock, and after reaching predetermined tensile force, carry out machined again, avoid material because of being out of shape the inconsistent error that occurs, improved assembly precision.Guaranteed the real negative common difference of the straight and pin-and-hole pitch-row of every leaf spring in the leaf spring assembling so effectively, reached the theoretical requirement of design, guaranteed that every group of leaf spring assembles stressed unanimity in the vibrating device, oscillating curve adheres to specification during the vibrating device test run, all around beat is all within tolerance, receive expected effect, improved the service life of product.
