Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation.It should be noted that at this, the explanation for these way of example understands the present invention for helping, but does not form limitation of the invention.
As shown in Figure 1, Figure 2 and Figure 3, base 1 is installed with 2 back-up blocks 2 and is fixedly connected with block 5 with 2, wherein, back-up block 2 is with to be fixedly connected with block 5 matched combined paired, and the mode adopting foundation bolt to connect is fixedly mounted on base 1, back-up block 2 be fixedly connected with the sliding tray 21 and 51 block 5 being all respectively arranged with and matching with foundation bolt, the object arranging this sliding tray is that hold down gag can adjust as required.Back-up block 2 is hinged with the lower removable of contiguous block 4, be respectively equipped with extension spring 3 to the small sircle hole coordinated being fixedly connected with in the middle part portion on block 5 and contiguous block 4, the two ends of extension spring 3 are caught on respectively and are arranged on and are fixedly connected with block 5 and are flexibly connected on the small sircle hole of block 4 middle part, ensure that extension spring 3 is in original state after installing.Support wheel 7 can adopt duroplasts material to process, also cast iron or steel can be adopted to process, but, by carrying out economic technique analysis to it, as preferred embodiment, the present embodiment adopts the support wheel of duroplasts material processing, because adopting duroplasts to compare other material has low price, be easy to the advantages such as processing, and the support wheel of duroplasts material processing can meet the requirement of silencer processing in the technical requirements such as structure stress.
The outer peripheral face of support wheel 7 is provided with friction sleeve 8, and friction sleeve 8 adopts flexible material, and the present embodiment adopts quality of rubber materials, because rubber is drawn materials conveniently, is easy to processing.The internal diameter of friction sleeve 8 is identical with the external diameter of friction pulley 7, and thickness is more than or equal to 5mm, and width is more than or equal to the width of friction pulley 7.
As depicted in figs. 1 and 2, in the technical scheme of the present embodiment, be arranged on be fixedly connected with block 5, contiguous block 4 and the support wheel 7 on pressure-driven block 10 and friction sleeve 8 all identical.By adjusting the link position of sliding tray and the foundation bolt be fixedly connected with on block 5 and back-up block 2, the tangent line of the rotation rail trace of the support wheel be fixedly connected with on block 5 and contiguous block 4 is adjusted on an axis.For pressure apparatus, after pressure actuated device installation, be movably articulated in the support wheel 7 in pressure-driven fast 10, two couple as shown in Figure 2 need be arranged on and be fixedly connected with between the combination that block 5 and contiguous block 4 form; After friction whirligig installation, also the needing of active friction wheel 17 is arranged on two couple as shown in Figure 2 and is fixedly connected with between the combination that block 5 and contiguous block 4 form.Be positioned at support wheel on pressure-driven block 10 and active friction wheel is installed without the need to symmetrical up and down, as one of the preferred version of the present embodiment, in the present embodiment scheme, the support wheel on pressure-driven block 10 and active friction wheel symmetry are installed, to a certain extent, when preventing because of silencer 9 radial force inequality, have the phenomenon moved axially once in a while.
As Fig. 1 with shown in 2, silencer 9 is placed horizontally on the support wheel be fixedly connected with on block 5 and contiguous block 4, gravitate, the support wheel be fixedly connected with on block 5 and contiguous block 4 relatively rotates, and be fixedly connected with block 5 and increase with the angle assembly that contiguous block 4 is formed, extension spring 3 is stretched, because the reaction force of extension spring 3, the angle being fixedly connected with block 5 and contiguous block 4 keeps fixing under the active force of silencer 9 and extension spring 3, and silencer 9 keeps fixing under the effect of support wheel 7.Because friction sleeve 8 belongs to quality of rubber materials, concerning the outer peripheral face of silencer 9, create good protected effect.Silencer 9 can produce downward displacement under gravity, and this displacement just in time can make silencer 9 press on the active friction wheel 17 of friction whirligig.The stepper motor 16 that the present embodiment adopts can choose the stepper motor of various step angle according to Production requirement, the present embodiment employing step angle is the direct current generator of 1.8 °, stepper motor just can be controlled by its corresponding supporting controller, at present, stepper motor is applied more and more extensive in many industrial circles.Rotated by the output shaft of vacant stepper motor 16, active friction wheel 17 is driven to rotate, active friction wheel is provided with active friction cover 18, active friction cover 18 cover has identical material with 8, because silencer 9 and the active friction on driving wheel 17 overlap the mutual rubbing action of 18, silencer 9 is improved with the coefficient of friction of active friction wheel 17, more be conducive to the rotation of silencer 9, silencer 9 also can carry out reversely rotating around axis with friction pulley, stepper motor turns a step angle that is 1.8 ° at every turn, active friction wheel 17 also can turn a step angle that is 1.8 °, and silencer 9 also can turn a step angle 1.8 °, thus, silencer 9 progressively can complete the circular motion around own axes.
As shown in Figure 2, the welder that the present invention adopts is welding equipment common on market, the bonding machine that the present embodiment is selected is that a set of consolidating to obtain board bonding machine, and the welding gun 11 of bonding machine is installed on the position of the outer peripheral face needs welding being placed in silencer 9 by the top of workbench 14.Silencer, under the effect of support wheel 7 and active friction wheel 17, around own axis, only needs to move axially welding gun, can complete the outer peripheral face 360 ° welding to silencer.
As shown in Figure 1, hold down gag includes extension spring 3, extension spring 3 not only can provide the counteractive support power to silencer, and to a certain extent, can by the decline displacement of adjustment silencer 9, the shown mechanism be made up of fixed support block 5 and contiguous block 4 etc. can meet the welding demand of the silencer of plurality of specifications.As shown in Figure 2, the mechanism be made up of pressure-driven block 10, fixed support block 12 and cylinder 13 etc. not only completes exerting pressure to silencer 9, prevent the outer peripheral face of silencer 9 because cause silencer 9 to rotate not with the contact force of active friction wheel 17, and ensure that silencer 9 does not produce chattering and causes welding to occur quality problems in rotation process.Friction drive device shown in Fig. 2, not only structure is simple, practical and convenient, and maintenance cost is very low, has important practical significance to production and maintenance.
Below by reference to the accompanying drawings the preferred embodiments of the disclosure and embodiment are elaborated, but the present invention is not limited to appeal embodiment and embodiment, in the ken that those skilled in the art possess, can also make a variety of changes without departing from the inventive concept of the premise.
