The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The specific structure of the positioning device for heliostats of the embodiment of the present invention is described below with reference to fig. 1 to 5.
The positioning device of the heliostat of the embodiment of the invention is used for positioning the bracket 4. As shown in fig. 6, the heliostat includes a main beam 5 and a bracket 4 attached to the main beam 5. In the actual processing process, the main beam 5 and the support 4 can be connected in advance by bolts without being locked, or the main beam 5 and the support are not connected in advance, then move to the positioning device under the transportation of the transportation device, and the support 4 and the main beam 5 are connected by welding through the robot 6 positioned below the fixing column of the positioning device after the accurate positioning of the positioning device. As shown in fig. 1-2, the positioning device includes a fixing frame 1, a positioning mechanism 2 and a tensioning mechanism 3. Mount 1 is configured to support frame 4, positioning mechanism 2 is connected on mount 1, positioning mechanism 2 includes first locating module 21 and second locating module 22, first locating module 21 is established on mount 1, first locating module 21 is configured to fix a position girder 5 along 5 axial directions of girder, second locating module 22 is established on mount 1, second locating module 22 is configured to fix a position girder 5 along 5 radial directions of girder, straining mechanism 3 is a plurality of, the spaced connection of a plurality of straining mechanisms 3 is on mount 1, every straining mechanism 3 all includes slip table module 31 and pull rod module 32, slip table module 31 is established on mount 1 along upper and lower direction slidable, pull rod module 32 is movably established on slip table module 31, the one end of pull rod module 32 cooperates with support 4 with locating support 4.
It can be understood that, in the in-service use process, after placing support 4 and girder 5 on mount 1, first locating module 21 and second locating module 22 can be fixed girder 5 along two axial and radial directions, have avoided welding girder 5 and support 4's in-process girder 5 to take place to rock the phenomenon that makes support 4 appear positioning deviation like this to the radian after heliostat processing has been guaranteed.
In addition, the positioning device of the invention further comprises a plurality of tensioning mechanisms 3 and sliding table modules 31 which are connected to the fixed frame 1, and after the main beam 5 is fixed on the fixed frame 1, the plurality of sliding table modules 31 can be adjusted to enable certain surfaces of the plurality of sliding table modules 31 to be positioned on the same plane, namely the plurality of sliding table modules 31 have the same positioning reference. After the positioning reference is determined, each sliding table module 31 can be driven to a specified position according to actual needs, and then the pull rod module 32 can be used for ejecting the support 4 to complete the positioning of the support 4. It should be noted that, in the invention, before the support 4 is pushed by the pull rod module 32, the plurality of sliding table modules 31 are first located on the same positioning reference, the positioning accuracy of the support 4 can be ensured to be aligned to the greatest extent by adjusting the sliding table modules 31 and the support 4 according to actual needs, and the positioned support 4 can be made to approach to the set radian as much as possible, so that the heliostat with a small error after being processed is ensured, and the light-gathering requirement is well met.
According to the positioning device of the heliostat, provided by the embodiment of the invention, as the first positioning module 21 and the second positioning module 22 for fixing the main beam 5 are arranged, the main beam 5 is prevented from shaking, the positioning precision of the support 4 is ensured, and the processing deviation of the heliostat is reduced. Because tensioning mechanism 3 and slip table module 31 that have locating support 4, and slip table module 31 can be used for confirming the location benchmark, has guaranteed the positioning accuracy of support 4 better to the machining error of heliostat has been reduced.
It should be added here that a heliostat may include a main beam 5 and a plurality of supports 4, and each support 4 may be tensioned by a plurality of tensioning mechanisms 3. For example, in some embodiments, the heliostat includes a main beam 5 and eight supports 4, with 6 positioning points on each support 4. Correspondingly, the positioning device of the heliostat comprises a positioning mechanism 2 and 48 tensioning mechanisms 3.
In some embodiments, as shown in fig. 5, the sliding table module 31 includes a sliding rail 311 and a sliding block 312, the sliding rail 311 is connected to the fixed frame 1, the sliding block 312 is slidably disposed on the sliding rail 311 along the up-down direction, and the pull rod module 32 is connected to the sliding block 312. It can be understood that, according to the foregoing, before the positioning of the bracket 4 is realized, the plurality of sliding table modules 31 need to be located on the same reference plane, and the matching manner of the sliding rails 311 and the sliding blocks 312 is adopted, so that not only can the plurality of sliding blocks 312 be easily located on the same reference plane, but also the sliding blocks 312 are prevented from deviating in the sliding process, and the accuracy of the reference plane is improved.
It should be noted that, in the present invention, the driving mechanism of the slider 312 may be implemented as a motor or an air cylinder, and the driving mechanism of the slider 312 is not specifically limited herein, and the driving mechanism of the slider 312 may be selected according to actual needs. Of course, in other embodiments of the present invention, the sliding table module 31 may also be a screw nut, a crank block 312, or other mechanical structures that output linear motion, and is not limited to the sliding rail 311 and the sliding block 312 mechanism in this embodiment.
In some embodiments, as shown in fig. 5, the pull rod module 32 includes a fixed block 321, an air cylinder 322, and a pull rod assembly 323, where the fixed block 321 is connected to the sliding table module 31, the fixed block 321 defines an accommodating cavity 3211, and an outer sidewall of the accommodating cavity 3211 is provided with a calibration mark 3212, the air cylinder 322 is connected to the fixed block 321, a piston rod of the air cylinder 322 extends into the accommodating cavity 3211, one end of the pull rod assembly 323 is connected to the piston rod, the other end of the pull rod assembly extends out of the accommodating cavity 3211 to be matched with the bracket 4, and the piston rod can drive the pull rod assembly. It can be understood that, because the fixed block 321 is provided with the calibration mark 3212, and the fixed block 321 is connected to the sliding table module 31, the reference positioning of the sliding table module 31 is facilitated, and the positioning reference operation of the sliding table module 31 before the positioning of the bracket 4 is facilitated. In addition, in the practical process, after the positioning reference of the sliding table module 31 is determined and each sliding table module 31 is adjusted according to the actual requirement, the cylinder 322 arranged on the fixed block 321 can drive the pull rod assembly 323 to jack the bracket 4. Therefore, the support 4 can be conveniently jacked up by the pull rod assembly 323, the support 4 can be firmly fixed at a certain position by the pull rod assembly 323, and the machining precision of the heliostat is improved. Of course, it should be noted that in other embodiments of the present invention, the motor structure for driving the lever assembly 323 is not limited to the cylinder of the present embodiment.
In some embodiments, as shown in fig. 5, an end of the pull rod assembly 323 extending out of the accommodating cavity 3211 is provided with a matching pin 3231b, the matching pin 3231b is adapted to match an avoiding hole on the bracket 4, the matching pin 3231b has a releasing position and a top-dead position, in the releasing position, the matching pin 3231b is disposed opposite to the avoiding hole and can penetrate out of the avoiding hole, and in the top-dead position, the matching pin 3231b is disposed offset from the avoiding hole and is stopped against the bracket 4 to stop the bracket 4. It will be appreciated that the cooperating pin 3231b can move from the release position to the top dead center position to dead center the bracket 4 during upward movement of the piston rod of the cylinder 322 driving the lever assembly 323. After the support 4 and the main beam 5 are welded, the piston rod of the cylinder 322 drives the pull rod assembly 323 to move downwards so that the matching pin 3231b can move to the release position from the top dead position, and then the sliding table module 31 drives the whole pull rod assembly 323 to move upwards, so that the matching pin 3231b can penetrate out of the avoiding hole, the positioning of the pressing mechanism on the support 4 is released, the first positioning module 21 and the second positioning module 22 are driven to release the locking on the main beam 5, and therefore the heliostat can be separated from the positioning device, namely the heliostat can move to the next station under the transportation of the transportation device. Therefore, production line and automation of heliostat production are well realized, and heliostat production efficiency is improved.
In some embodiments, as shown in fig. 5, tie rod assembly 323 includes a tie rod 3231, a connecting sleeve 3232, and a ball adjustment lever 3234. One end of a pull rod 3231 extends out of the accommodating cavity 3211, a matching pin 3231b is arranged at one end of the pull rod 3231 extending out of the accommodating cavity 3211, a curved groove 3231a extending along the axial direction of the pull rod 3231 is formed in the circumferential surface of the pull rod 3231, one end of a connecting sleeve 3232 is matched on the pull rod 3231, the other end of the connecting sleeve 3232 is connected with the piston rod through a connecting head 3233, a ball adjusting rod 3234 is connected on the bottom wall of the accommodating cavity 3211, one end of the ball adjusting rod 3234 is matched with a ball, and the ball is matched in the curved groove 3231 a. During the up and down movement of the piston rod driving connection sleeve 3232 and the pull rod 3231, the balls can roll in the curved groove 3231a to rotate in cooperation with the pull rod 3231, and the cooperation pin 3231b rotates between a release position and a dead-stop position.
It can be understood that, in the actual use process, when the sliding table module 31 moves to the designated position, the fitting pin 3231b is located below the avoiding hole, and at this time, the cylinder 322 drives the connecting sleeve 3232 and the pull rod 3231 to move upwards, and during the upward movement of the pull rod 3231, the balls roll in the curved groove 3231a and are connected to the ball adjusting rod 3234 fixed on the bottom wall of the accommodating cavity 3211, so during the rolling of the balls, the ball adjusting rod 3234 drives the pull rod 3231 to rotate, so that the fitting pin 3231b moves from the releasing position to the top dead position to thereby top dead the bracket 4. Therefore, only one air cylinder 322 is needed to realize the rotation movement and the vertical movement of the matching pin 3231b, the structure of the pull rod module 32 is simplified, and the production cost of the tensioning mechanism 3 is reduced.
In some specific embodiments, as shown in fig. 5, the pull rod assembly 323 further includes a guide seat 3235, the guide seat 3235 is connected to the bottom wall of the accommodating cavity 3211 and is sleeved on the pull rod 3231, and the ball adjustment rod 3234 is inserted through the guide seat 3235. It can be understood that, since the guide seat 3235 is sleeved on the pull rod 3231, the ball adjusting rod 3234 is inserted into the guide seat 3235. Therefore, the ball is always in a relatively closed space in the rolling process, so that the phenomenon that the ball slides down is avoided, and the phenomenon that the ball rolls unsmoothly due to the fact that dirt is stained on the surface of the ball is also avoided. It should be additionally noted that, in order to reduce the torsion force applied to the piston rod during the rotation of the drawbar 3231, the drawbar 3231 may be threadedly or otherwise rotatably connected to the connection sleeve 3232.
In some alternative embodiments, the ball-adjusting rod 3234 is connected to the guide seat 3235 by a thread, so that the acting force of the ball-adjusting rod 3234 on the pull rod 3231 can be better ensured, and the ball-adjusting rod 3234 can drive the pull rod 3231 to rotate during the movement of the piston rod of the cylinder 322. Of course, in other embodiments of the invention, the ball adjustment lever 3234 can be connected to the guide housing 3235 by a pin, a snap, or other means.
In some alternative embodiments, the ball adjustment lever 3234 is provided with oil holes and lubrication passages that communicate with the curved groove 3231 a. From this, the user can inject lubricating oil in the crooked type groove 3231a of orientation through the oiling hole to guarantee that the ball can be comparatively smooth and easy slip in crooked type groove 3231a, thereby avoid the dead phenomenon of ball card to take place.
Of course, in other embodiments of the present invention, the pulling rod assembly 323 may include two driving members, one driving member driving the pulling rod 3231 to move up and down, and the other driving member driving the pulling rod 3231 to rotate so that the engaging pin 3231b and the avoiding hole are aligned or staggered.
In some embodiments, as shown in fig. 3, there are two first positioning modules 21, two first positioning modules 21 are spaced apart, each first positioning module 21 includes a driving member 211 and a clamping member 212, the driving member 211 is connected to the fixing frame 1, and the clamping member 212 is connected to the driving member 211. The two clamping members 212 are configured to respectively abut against two axial ends of the main beam 5 to clamp the main beam 5 under the driving of the two driving members 211. Therefore, when the transportation device transports the main beam 5 to the positioning device, the driving part 211 can drive the clamping part 212 to stop against the two axial ends of the main beam 5 to complete clamping of the main beam 5, so that the main beam 5 is prevented from moving along the axial direction, and the positioning accuracy of the support 4 is ensured. It should be noted that, in the embodiment of the present invention, the driving member 211 may be a cylinder, and the clamping member 212 is connected to a piston rod of the cylinder. The drive member 211 may also be a motor driven lead screw nut to which the clamping member 212 is connected. That is, the shape of the driving member 211 can be selected according to actual needs, and the structure of the driving member 211 is not particularly limited.
In some more specific embodiments, the retaining hook 2121 is disposed on the clamping member 212, and the retaining hook 2121 is configured to hook on the positioning block 51 of the main beam 5. Therefore, the clamping action of the clamping piece 212 on the main beam 5 can be better ensured, and the main beam 5 is better prevented from axial movement.
Of course, in other embodiments of the present invention, there may be two clamping members 212, and the driving member 211 can drive the clamping members 212 to stop against the circumferential surface of the main beam 5, so that the two clamping members 212 lock the main beam 5, thereby preventing the main beam 5 from moving axially.
In some embodiments, the second positioning module 22 is plural, and the plural second positioning modules 22 are spaced along the axial direction of the main beam 5. It can be understood that, the second positioning module 22 can better ensure the positioning of the main beam 5 in the radial direction, so as to avoid the radial shaking of the main beam 5.
In some embodiments, as shown in fig. 4, the second positioning module 22 includes a sleeve 221 and a sliding column 222, the sleeve 221 is connected to the fixing frame 1, the sliding column 222 is slidably disposed in the sleeve 221, a positioning protrusion 2221 is disposed on a lower end surface of the sliding column 222, and the positioning protrusion 2221 is matched with the positioning hole 511 on the main beam 5.
