Technical Field
[0001] The present application relates to the field of parts processing, and in particular to a rapid positioning device for double-floating composite parts. Background Art
[0002] Cars are a common means of transportation. A car is composed of many parts and has many processing steps. At the same time, the molding molds and processing molds involved are also various. After the molding molds are produced, some molds may need to be adjusted. Generally, a clamping and positioning device is required to fix the parts and then adjust the parts.
[0003] The existing clamping and positioning device generally has two clamping and positioning blocks. The part to be fixed is placed between the two clamping and positioning blocks, and then the two clamping and positioning blocks clamp the sides of the part to complete the positioning of the part, and then the part is processed.
[0004] When clamping parts, the existing clamping and positioning blocks usually directly contact the side of the part for clamping. When the part is placed on the workbench, it relies entirely on the part's own gravity to contact the workbench. When the clamping and positioning blocks clamp the part, the part may be supported by the clamping and positioning blocks, resulting in the part being unable to contact or be parallel to the workbench, and the part may be offset during processing. Utility Model Content

The present application provides a double-lift composite part rapid positioning device.
[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

Then, when it is necessary to change the processing angle of the part during processing, the rotation mechanism can be used to drive the processing table to rotate, so that the part can remain flush with the processing table, reducing the possibility that the part will not contact the processing table when being positioned.

[0013] Furthermore, two symmetrical synchronization rods are fixed on the threaded ring, and the two synchronization rods are fixedly connected to corresponding sliding rods.
[0014] By adopting the above technical solution, when the threaded ring moves, the threaded ring drives the two synchronization rods at the same time, and the synchronization rods drive the sliding rods to move, thereby conveniently driving the two extrusion bevel blocks on the positioning block to move simultaneously.
[0015] Furthermore, two symmetrical support bars are fixed on the inclined surface of the extrusion oblique block, and a plurality of lower pressing rollers are rotatably connected between the two support bars.
[0016] By adopting the above technical solution, when the inclined surface on the extrusion bevel block contacts the part, the lower pressure roller on the extrusion bevel block contacts the part, thereby reducing the possibility of wear between the contact bevel block and the part.
[0017] Furthermore, a rubber layer is fixed on the surface of the plurality of lower pressing rollers.

[0020] By adopting the above technical solution, the fixing rod is pulled to disengage the fixing rod from the fixing hole on the second rotating table, and then the processing table is directly rotated to allow the processing table to drive the second rotating table to rotate on the first rotating table, thereby making it easy to adjust the angle of the processing table and the parts on the processing table.
[0021] Furthermore, a fixing spring is provided between the fixing rod and the fixing block, and both ends of the fixing spring are fixedly connected to the fixing rod and the fixing block.

[0032] The following is combined with Figure 1 —4 Provide further details of this application.
[0033] The embodiment of the present application discloses a rapid positioning device for dual-floating composite parts.
[0034] Reference Figure 1 、 Figure 2 and Figure 3A double-floating composite part rapid positioning device includes a processing table 1, a support seat 2 is provided at the bottom of the processing table 1, a rotating mechanism 7 is provided between the processing table 1 and the support seat 2, two symmetrical positioning blocks 3 are provided on the processing table 1, and the positioning blocks 3 are L-shaped, one of the positioning blocks 3 is fixedly connected to the processing table 1, and a threaded block 5 is fixed on the other positioning block 3, and the threaded block 5 is slidably connected to the processing table 1, and a positioning threaded rod 4 is rotatably connected to the processing table 1, and the positioning threaded rod 4 passes through the threaded block 5 and is threadedly connected to the threaded block 5, and an extrusion adjustment mechanism 6 is provided on both positioning blocks 3.
[0035] When using the positioning device, first place the part to be positioned between the two positioning blocks 3, then rotate the positioning threaded rod 4, and let the threaded block 5 drive the positioning block 3 to move, and then the two positioning blocks 3 clamp the part to position the part, and then use the extrusion adjustment mechanism 6 to further extrude and fix the part, so that the part moves toward the processing table 1, so that the part contacts the processing table 1, and the position where the part contacts the processing table 1 remains stable. Then, during the processing process, when it is necessary to change the processing angle of the part, the rotation mechanism 7 can be used to drive the processing table 1 to rotate, so that the angle of the part on the processing table 1 changes. After the part is clamped and positioned by the two positioning blocks 3, the extrusion adjustment mechanism 6 is used to further push the clamped part so that the part contacts the processing table 1 tightly, so that the part can remain flush with the processing table 1, reducing the possibility that the part does not contact the processing table 1 when being positioned.
[0036] Reference Figure 1 、 Figure 2 and Figure 3 The extrusion adjustment mechanism 6 includes two extrusion oblique blocks 61 arranged on the positioning block 3, the inclined surface of the extrusion oblique block 61 faces the processing table 1, a sliding rod 63 is fixed on the extrusion oblique block 61, a sliding groove 62 is provided on the positioning block 3, the sliding rod 63 is located in the sliding groove 62 and is slidably connected to the positioning block 3, and a pressing component 64 is provided between the two sliding rods 63.
[0037] In addition, the downward pressing component 64 includes a downward pressing motor 641 arranged on the positioning block 3, a support block 642 is fixed on the downward pressing motor 641, the support block 642 is fixedly connected to the positioning block 3, a downward pressing threaded rod 643 is fixed to the output end of the downward pressing motor 641, and a threaded ring 644 is threadedly connected to the downward pressing threaded rod 643.
[0038] In addition, two symmetrical synchronization rods 645 are fixed on the threaded ring 644 , and the two synchronization rods 645 are fixedly connected to the corresponding sliding rods 63 .
[0039] Furthermore, two symmetrical support bars 65 are fixed on the inclined surface of the extrusion oblique block 61 , and a plurality of lower pressing rollers 66 are rotatably connected between the two support bars 65 .
[0040] After the two positioning blocks 3 clamp the part, the pressing motor 641 drives the pressing threaded rod 643 to rotate, and the threaded ring 644 on the pressing threaded rod 643 approaches the positioning block 3, and then the threaded ring 644 drives the synchronous rod 645, and the synchronous rod 645 drives the sliding rod 63, and the sliding rod 63 drives the extruding bevel 61, and the extruding bevel 61 moves toward the part, and then the inclined surface on the extruding bevel 61 hits the part, and the extruding bevel 61 squeezes the part, so that the part is squeezed toward the processing table 1, so that the part is tightly against the processing table 1. When the inclined surface on the extruding bevel 61 hits the part, the lower pressing roller 66 on the extruding bevel 61 hits the part, and when the extruding bevel 61 moves, the part slides on the extruding bevel 61, and by squeezing the extruding bevel 61 toward the part, the part is squeezed toward the processing table 1, so that after the part is positioned, the part is made to hit the processing table 1, reducing the possibility of part deviation, and further improving the stability of the clamped part.
[0041] Reference Figure 2 and Figure 3 A rubber layer is fixed on the surface of the plurality of lower pressing rollers 66. The lower pressing rollers 66 on the extrusion ramp 61 contact the parts. When the lower pressing rollers 66 rotate, the rubber layer on the lower pressing rollers 66 contacts the parts. By fixing a layer of rubber on the surface of the lower pressing rollers 66, the possibility of wear between the lower pressing rollers 66 and the parts during the extrusion process can be further reduced.
[0042] Reference Figure 1 、 Figure 2 and Figure 4 The rotating mechanism 7 includes a rotating table 71 fixed on the support base 2, and the rotating table 71 is rotatably connected to the rotating table 2 72. The rotating table 2 72 is fixedly connected to the processing table 1. A fixed block 73 is fixed on the rotating table 71, and a fixed rod 74 is slidably connected to the fixed block 73. A number of evenly distributed fixing holes 75 are opened on the side of the rotating table 2 72, and the fixing rods 74 correspond to the fixing holes 75.
[0043] In addition, a fixing spring 76 is provided between the fixing rod 74 and the fixing block 73 , and both ends of the fixing spring 76 are fixedly connected to the fixing rod 74 and the fixing block 73 .
[0044] When the angle of the positioned part needs to be adjusted, the fixing rod 74 is pulled to disengage the fixing rod 74 from the fixing hole 75 on the rotating table 2 72, and then the processing table 1 is directly rotated to allow the processing table 1 to drive the rotating table 2 72 to rotate on the rotating table 1 71. When the processing table 1 is rotated to the appropriate position, the fixing rod 74 is released, and the fixing rod 74 is inserted into the new fixing hole 75 on the rotating table 2 72 under the action of the fixing spring 76, so that the rotating table 1 71 and the rotating table 2 72 cannot rotate. By utilizing the rotating table 2 72 to support the processing table 1 to rotate on the rotating table 1 71, the angle of the processing table 1 and the parts on the processing table 1 can be easily adjusted.
[0045] Working principle: When using the positioning device, first place the part to be positioned between the two positioning blocks 3, then rotate the positioning threaded rod 4, and let the threaded block 5 drive the positioning block 3 to move, and then the two positioning blocks 3 clamp the part to position the part. After the two positioning blocks 3 clamp the part, the downward pressure motor 641 drives the downward pressure threaded rod 643 to rotate, and the threaded ring 644 approaches the positioning block 3 on the downward pressure threaded rod 643, and then the threaded ring 644 drives the synchronization rod 645, and the synchronization rod 645 drives the sliding rod 63, and the sliding rod 63 drives the extrusion bevel block 61, and the extrusion bevel block 61 moves toward the direction of the part, and then the inclined surface on the extrusion bevel block 61 contacts at zero. When the angle of the positioned part needs to be adjusted, the fixing rod 74 is pulled to disengage the fixing rod 74 from the fixing hole 75 on the second rotating table 72, and then the processing table 1 is directly rotated to allow the processing table 1 to drive the second rotating table 72 to rotate on the first rotating table 71. When the processing table 1 is rotated to the appropriate position, the fixing rod 74 is released, and the fixing rod 74 is inserted into the new fixing hole 75 on the second rotating table 72 under the action of the fixing spring 76, so that the first rotating table 71 and the second rotating table 72 cannot rotate, thereby completing the adjustment of the processing table 1 and the angle of the parts on the processing table 1.
