Description

Technical Field

[0001] The invention belongs to the technical field of metal component clamps, and in particular relates to a clamp for special-shaped metal components. Background Art

[0002] Metal processing refers to the cutting, forming, welding, forging and other processing of metal materials through mechanical processing, hot processing, cold processing and other methods to manufacture various metal parts or finished products. These processing processes can include milling, turning, drilling, grinding, stamping, bending, welding and other operations. The purpose is to process metal raw materials into parts or products that meet specific purposes according to design requirements and technical specifications. Metal processing occupies an important position in the manufacturing industry and is widely used in automobile manufacturing, aerospace, mechanical equipment, electronic products and other fields. Before processing metal parts, they need to be fixed first, which requires specific fixtures to ensure the stability of clamping, thereby ensuring the effect of subsequent processing.

[0003] Most of the existing clamps for metal components are designed for specific clamping of a certain type of metal component. For example, the design of metal components with circular structures can adjust the clamp according to the different diameters. When clamping some special-shaped metal components, specific clamps are often required to complete the clamping. However, this also leads to a limited scope of use of this type of clamp, and the design and production costs for a variety of metal components will increase. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the prior art and provide a clamp for special-shaped metal components.

[0005] The technical solution adopted to solve the above technical problems is: to provide a fixture for special-shaped metal components, including a supporting base mechanism, the top of the supporting base mechanism is fixedly connected to a workbench limiting mechanism, and the top of the supporting base mechanism is rotatably connected to a rotating gear disk;

[0006] A plurality of rolling steel balls are arranged between the top of the support base mechanism and the rotating gear disc, a vortex groove is provided on the top of the rotating gear disc, and a driving motor assembly and a protective shell are fixedly connected to one side of the support base mechanism;

[0007] The output end of the driving motor assembly is fixedly connected with a driving gear, and the workbench limiting mechanism is slidably connected with a plurality of clamping track mechanisms, and a plurality of the clamping track mechanisms are slidably connected with a clamping mechanism.

[0008] Furthermore, the support base mechanism comprises a device bottom shell, the top of the inner wall of the device bottom shell is fixedly connected to an inner ring plate, and the top of the outer wall of the device bottom shell is fixedly connected to an integral outer shell sleeve.

[0009] Through the above technical solution, the rotation of the rotating toothed disc is completed through the integrated inner ring plate and multiple rolling steel balls, thereby completing the driving of the clamp.

[0010] Furthermore, the workbench limiting mechanism includes a bottom ring plate fixedly connected to the top of the supporting base mechanism, the top of the bottom ring plate is fixedly connected to an integral connecting ring plate, the inner wall of the integral connecting ring plate is fixedly connected to two first arc-shaped limiting rails, and the two first arc-shaped limiting rails are each provided with a first arc-shaped groove, both sides of the inner wall of the integral connecting ring plate are fixedly connected to a center connecting rod, a connecting circular plate is fixedly connected between the two center connecting rods, the bottom of the connecting circular plate is fixedly connected to a limiting circular plate, the outer wall of the connecting circular plate is fixedly connected to two second arc-shaped limiting rails, and the two second arc-shaped limiting rails are each provided with a second arc-shaped groove.

[0011] Through the above technical solution, when installing the clamping rail mechanism, the number of clamping points and the distribution of the clamping points on the workbench limiting mechanism are determined according to the shape of the special-shaped metal component. After the clamping points are determined, multiple clamping rail mechanisms are inserted from both ends of the two first arc-shaped limiting rails and the two second arc-shaped limiting rails, so that the multiple clamping rail mechanisms can slide between the inner wall of the integrally connected ring plate and the outer wall of the connecting circular plate.

[0012] Furthermore, the clamping rail mechanism includes a limiting rail shell slidably connected to the workbench limiting mechanism, and the two ends of the limiting rail shell are respectively fixedly connected with an outer end limiting convex plate and an inner end limiting convex plate, and the tops of the outer end limiting convex plate and the inner end limiting convex plate are both provided with arc-shaped limiting blocks, and the centers of the two arc-shaped limiting blocks are fixedly connected with a first stud, and locking studs are respectively passed through the two sides of the two arc-shaped limiting blocks, and the outer walls of the two first studs are both sleeved with first gaskets, and the two first studs are both spirally connected with a first locking threaded block.

[0013] Through the above technical scheme, after installing multiple clamping rail mechanisms, the first studs on the two arc-shaped limit blocks in the clamping rail mechanism are respectively inserted into the through holes in the center of the outer end limit convex plate and the inner end limit convex plate, and then the locking studs are used to complete the fixation between the two arc-shaped limit blocks and the outer end limit convex plate and the inner end limit convex plate, and the first gaskets are respectively sleeved on the two locking studs and the first locking thread blocks are spirally connected, and the multiple clamping rail mechanisms are moved so that the multiple clamping rail mechanisms all reach the corresponding clamping point positions, and then the first locking thread blocks at both ends are rotated to squeeze the first gasket in a spiral manner, thereby completing the fixing of the entire clamping rail mechanism between the first arc-shaped limit rail and the second arc-shaped limit rail.

[0014] Furthermore, the outer end limiting protrusion and the inner end limiting protrusion are respectively fitted with the inner wall of the integrally connected ring plate and the outer wall of the connecting circular plate, and circular holes and threaded holes corresponding to the first stud and the two locking studs are respectively opened on the outer end limiting protrusion and the inner end limiting protrusion, and the two arc-shaped limiting blocks are respectively clamped between the inner walls of the first arc-shaped groove and the second arc-shaped groove.

[0015] Through the above technical scheme, it is ensured that the limiting track shell can be limited by the outer end limiting convex plate and the inner end limiting convex plate, so that it can stably slide between the first arc-shaped limiting track and the second arc-shaped limiting track. At the same time, the circular hole and the two threaded holes on the outer end limiting convex plate and the inner end limiting convex plate complete the fixation between the outer end limiting convex plate and the inner end limiting convex plate and the locking stud.

[0016] Furthermore, the clamping mechanism includes an adjusting sliding block slidably connected inside the clamping rail mechanism, one side of the adjusting sliding block is fixedly connected to an extension connecting block, the top of the extension connecting block is fixedly connected to a second stud, the outer wall of the second stud is sleeved with a second gasket, the second stud is spirally connected to a second locking thread block, the top of the adjusting sliding block is fixedly connected to a clamping block, the top inner surface of the clamping block is fixedly connected to two return springs, a limiting sliding block is fixedly connected between the bottoms of the two return springs, and the bottom of the limiting sliding block is fixedly connected to an arc-shaped tooth block.

[0017] By means of the above technical scheme, after fixing multiple clamping rail mechanisms, the driving motor assembly is started to drive the driving gear to rotate, thereby driving the rotating toothed disc meshing with it. At this time, the clamping blocks on the multiple clamping rail mechanisms are pushed one by one to slide toward the center of the overall clamp, so that the arc-shaped tooth blocks at the bottom of multiple limit sliding blocks are all meshed with the vortex grooves at the top of the rotating toothed disc. The meshed arc-shaped tooth blocks will continuously drive the arc-shaped tooth blocks and the limit sliding blocks to move under the action of the rotation of the vortex grooves, and move toward the placed metal component under the limit of the limit rail shell and the adjustment sliding block until the clamping block contacts the surface of the metal component. At this time, the overall clamping mechanism cannot move under the limit of the clamping block, and the rotating toothed disc that continues to rotate will squeeze the arc-shaped tooth blocks through the vortex grooves. The arc-shaped tooth block, due to the inclined surface between the vortex groove and the arc-shaped tooth block, will cause the vortex groove to squeeze the arc-shaped tooth block upward along the inclined surface and compress the two return springs at the same time until the arc-shaped tooth block shrinks inside the adjusting sliding block. Under the elastic force of the return spring, the arc-shaped tooth block pops out and engages with the vortex groove of the next circle, and then the arc-shaped tooth block continues to be squeezed upward by the vortex groove. The process is repeated. When the clamping blocks in the multiple clamping mechanisms are completely in contact with the surface of the special-shaped metal component, the drive motor assembly stops rotating. At this time, the position of the clamping mechanism is maintained and the multiple second locking thread blocks are rotated so that the second gasket is squeezed by the spiral, thereby completing the fixation of the overall clamping mechanism to the clamping track mechanism, thereby completing the clamping and fixation of the special-shaped metal component at multiple clamping points.

[0018] Furthermore, the vortex groove and the arc-shaped tooth block are meshed, and the cross-sections of the vortex groove and the arc-shaped tooth block are both triangular structures, and the bottom of the vortex groove is distributed in intervals and penetrates the arc-shaped through holes of the rotating gear disk.

[0019] Through the above technical scheme, it is ensured that the vortex groove can drive the movement of the entire clamping mechanism. At the same time, the triangular structure ensures that after the clamping block fits the surface of the special-shaped metal component, the rotation of the rotating toothed disc will not affect the clamping block that has reached the specified position until all the clamping blocks fit the surface of the metal component.

[0020] The beneficial effects of the present invention are as follows: (1) The present invention can determine the number of clamping points and the distribution of clamping points on the workbench limiting mechanism according to the shape of the special-shaped metal component by designing the workbench limiting mechanism, the clamping track mechanism and the clamping mechanism. After the clamping points are determined, multiple clamping track mechanisms are installed on the workbench limiting mechanism, so that the multiple clamping track mechanisms can slide between the inner wall of the integrally connected ring plate and the outer wall of the connecting circular plate, and can be adjusted at will, so that the multiple clamping track mechanisms reach the specified clamping points, and finally the first locking thread blocks at both ends are used to squeeze the first gasket in a spiral manner, thereby completing the fixing of the overall clamping track mechanism between the first arc-shaped limiting track and the second arc-shaped limiting track. This method can achieve planar clamping for metal components of various structures, greatly improving the scope of use of the clamp; (2 ) The present invention designs a rotating toothed disc, a spiral groove, a clamping track mechanism and a clamping mechanism. The rotation of the rotating toothed disc and the spiral groove drives the arc-shaped tooth block meshing therewith, and then drives the overall clamping mechanism to move until the clamping block contacts the surface of the metal component. At this time, the overall clamping mechanism cannot move due to the limitation of the clamping block, and the rotating toothed disc that continues to rotate will squeeze the arc-shaped tooth block through the spiral groove, and at the same time compress the two return springs until the arc-shaped tooth block shrinks inside the adjusting sliding block. When the clamping blocks in the multiple clamping mechanisms are completely in contact with the surface of the special-shaped metal component, the driving motor assembly stops rotating. At this time, the multiple second locking threaded blocks are rotated to maintain the position of the clamping mechanism, so that the second gasket is squeezed by the spiral, thereby completing the fixation of the overall clamping mechanism to the clamping track mechanism, thereby completing the clamping and fixation of the special-shaped metal component at multiple clamping points.

After determining the clamping points, multiple clamping track mechanisms 9 are placed from both ends of the two first arc-shaped limiting rails 203 and the two second arc-shaped limiting rails 208, so that the multiple clamping track mechanisms 9 can slide between the inner wall of the integrally connected ring plate 202 and the outer wall of the connecting circular plate 206, and the top of the supporting base mechanism 1 is rotatably connected with a rotating gear disc 3.

[0035] like Figure 1-Figure 9 As shown, a plurality of rolling steel balls 4 are arranged between the top of the supporting base mechanism 1 and the rotating gear disc 3, a vortex groove 5 is opened on the top of the rotating gear disc 3, and a driving motor assembly 6 and a protective shell 7 are fixedly connected to one side of the supporting base mechanism 1.

After installing multiple clamping track mechanisms 9, the first studs 905 on the two arc-shaped limit blocks 904 in the clamping track mechanism 9 are respectively inserted into the central through holes of the outer end limit convex plate 902 and the inner end limit convex plate 903, and then the locking studs 906 are used to complete the fixation between the two arc-shaped limit blocks 904 and the outer end limit convex plate 902 and the inner end limit convex plate 903, and the first gaskets 907 and the spirally connected studs 906 are respectively sleeved. The first locking thread block 908 moves the multiple clamping track mechanisms 9 so that the multiple clamping track mechanisms 9 all reach the corresponding clamping point positions, and then rotates the first locking thread blocks 908 at both ends to squeeze the first gasket 907 in a spiral manner, thereby completing the fixing of the entire clamping track mechanism 9 between the first arc-shaped limiting track 203 and the second arc-shaped limiting track 208, and the outer end limiting convex plate 902 and the inner end limiting convex plate 903 are respectively fitted with the inner wall of the integral connecting ring plate 202 and the outer wall of the connecting circular plate 206, and the outer end limiting convex plate 902 and the inner end limiting convex plate 903 are respectively provided with the first stud 9 05 and the circular holes and threaded holes corresponding to the two locking studs 906, the two arc-shaped limit blocks 904 are respectively engaged between the inner walls of the first arc-shaped groove 204 and the second arc-shaped groove 209, ensuring that the limit track shell 901 can be limited by the outer end limit convex plate 902 and the inner end limit convex plate 903, so that it can stably slide between the first arc-shaped limit track 203 and the second arc-shaped limit track 208, and at the same time, the circular holes and two threaded holes on the outer end limit convex plate 902 and the inner end limit convex plate 903 complete the fixation between the outer end limit convex plate 902 and the inner end limit convex plate 903 and the locking studs 906.

[0037] like Figure 1-Figure 11As shown, a plurality of clamping rail mechanisms 9 are slidably connected with clamping mechanisms 10, and the clamping mechanisms 10 include an adjusting sliding block 1001 slidably connected inside the clamping rail mechanism 9, one side of the adjusting sliding block 1001 is fixedly connected with an extension connection block 1002, the top of the extension connection block 1002 is fixedly connected with a second stud 1003, the outer wall of the second stud 1003 is sleeved with a second gasket 1004, the second stud 1003 is spirally connected with a second locking thread block 1005, the top of the adjusting sliding block 1001 is fixedly connected with a clamping block 1006, the top inner surface of the clamping block 1006 is fixedly connected with two return springs 1007, and the bottoms of the two return springs 1007 are fixedly connected between the limited position sliding block 100 8. The bottom of the limit sliding block 1008 is fixedly connected with an arc-shaped tooth block 1009. After fixing multiple clamping track mechanisms 9, start the driving motor assembly 6 to drive the driving gear 8 to rotate, driving the rotating toothed disk 3 engaged therewith. At this time, push the clamping blocks 1006 on the multiple clamping track mechanisms 9 one by one to slide toward the center of the overall fixture, so that the arc-shaped tooth blocks 1009 at the bottom of multiple limit sliding blocks 1008 are all engaged with the vortex grooves 5 at the top of the rotating toothed disk 3. The engaged arc-shaped tooth blocks 1009 will continuously drive the arc-shaped tooth blocks 1009 and the limit sliding block 1008 to move under the action of the rotation of the vortex grooves 5, and move toward the placed metal component under the limit of the limit track shell 901 and the adjustment sliding block 1001 until. After the clamping block 1006 contacts the surface of the metal component, the entire clamping mechanism 10 cannot move under the limitation of the clamping block 1006, and the rotating toothed disk 3 that continues to rotate will squeeze the arc-shaped tooth block 1009 through the spiral groove 5. Due to the inclined surface between the spiral groove 5 and the arc-shaped tooth block 1009, the spiral groove 5 will squeeze the arc-shaped tooth block 1009 upward along the inclined surface, and simultaneously compress the two return springs 1007 until the arc-shaped tooth block 1009 shrinks inside the adjusting sliding block 1001. Under the elastic force of the return spring 1007, the arc-shaped tooth block 1009 pops out and engages with the next circle of spiral groove 5, and then the arc-shaped tooth block 1009 continues to be squeezed upward by the spiral groove 5, and the process is repeated. When the clamping mechanism 10 has multiple After the block 1006 completely fits the surface of the special-shaped metal component, the driving motor assembly 6 stops rotating. At this time, the position of the clamping mechanism 10 is maintained and the multiple second locking thread blocks 1005 are rotated to make it screw-extrude the second gasket 1004, thereby completing the fixation of the entire clamping mechanism 10 on the clamping track mechanism 9, thereby completing the clamping and fixation of the special-shaped metal component at multiple clamping points. The vortex groove 5 and the arc-shaped tooth block 1009 are meshed, and the cross-sections of the vortex groove 5 and the arc-shaped tooth block 1009 are both triangular structures. The arc-shaped through holes that run through the rotating toothed disc 3 are distributed at intervals at the bottom of the vortex groove 5, ensuring that the vortex groove 5 can drive the entire clamping mechanism 10 to move. At the same time, the triangular structure realizes that after the clamping block 1006 fits the surface of the special-shaped metal component,The rotation of the rotating toothed disc 3 will not affect the clamping blocks 1006 that have reached the designated position until all the clamping blocks 1006 are in contact with the surface of the metal component.

[0038] The working principle of this embodiment is as follows. When in use, the number of clamping points and the distribution of the clamping points on the workbench limit mechanism 2 are determined according to the shape of the special-shaped metal component. After the clamping points are determined, multiple clamping track mechanisms 9 are inserted from both ends of the two first arc-shaped limit tracks 203 and the two second arc-shaped limit tracks 208, so that the multiple clamping track mechanisms 9 can slide between the inner wall of the integrally connected ring plate 202 and the outer wall of the connecting circular plate 206. At the same time, the first studs 905 on the two arc-shaped limit blocks 904 in the clamping track mechanism 9 are respectively inserted into the through holes in the center of the outer end limit convex plate 902 and the inner end limit convex plate 903, and then the locking studs 906 are used to complete the two arc-shaped limit blocks 904 and the outer end limit convex plate 902 and the inner end limit The convex plates 903 are fixed thereto, and the first gasket 907 and the first locking threaded block 908 are respectively sleeved on the two locking studs 906. At the same time, during the placement process, the plane outside the toothed disc 3 is rotated to squeeze the arc-shaped toothed block 1009, and then the reset spring 1007 is compressed by the limiting sliding block 1008, so that the arc-shaped toothed block 1009 is contracted inside the adjusting sliding block 1001. At this time, the multiple clamping track mechanisms 9 are moved so that the multiple clamping track mechanisms 9 all reach the corresponding clamping point positions, and then the first locking threaded blocks 908 at both ends are rotated to squeeze the first gasket 907 in a spiral manner, thereby completing the fixing of the entire clamping track mechanism 9 between the first arc-limiting track 203 and the second arc-limiting track 208;

[0039] The special-shaped metal component is placed on the top of the connecting circular plate 206 and placed in a suitable position so that it corresponds to the clamping point formed by the multiple clamping rail mechanisms 9, and the driving motor assembly 6 is started to drive the driving gear 8 to rotate, thereby driving the rotating toothed disk 3 engaged therewith. At this time, the clamping blocks 1006 on the multiple clamping rail mechanisms 9 are pushed one by one to slide toward the center of the overall clamp, so that the arc-shaped tooth blocks 1009 at the bottom of the multiple limiting sliding blocks 1008 are all engaged with the vortex grooves 5 at the top of the rotating toothed disk 3. The meshing arc-shaped tooth blocks 1009 will continuously drive the arc-shaped tooth blocks 1009 and the limiting sliding blocks 1008 to move under the action of the rotation of the vortex grooves 5, and move toward the placed metal component under the limit of the limiting rail shell 901 and the adjusting sliding block 1001, until the clamping block 1006 contacts the surface of the metal component. At this time, the overall clamping mechanism 10 cannot move under the limit of the clamping block 1006, and the rotating toothed disk 3 that continues to rotate will pass The arc-shaped tooth block 1009 is squeezed by the vortex groove 5. Due to the inclined surface between the vortex groove 5 and the arc-shaped tooth block 1009, the vortex groove 5 will squeeze the arc-shaped tooth block 1009 upward along the inclined surface, and simultaneously compress the two return springs 1007, until the arc-shaped tooth block 1009 shrinks inside the adjusting sliding block 1001, and then the arc-shaped tooth block 1009 pops out under the elastic force of the return spring 1007 to complete the meshing with the next circle of the vortex groove 5, and then the arc-shaped tooth block 1009 continues to be squeezed upward by the vortex groove 5, and the process is repeated. When the clamping blocks 1006 in the multiple clamping mechanisms 10 are completely in contact with the surface of the special-shaped metal component, the driving motor assembly 6 stops rotating. At this time, the position of the clamping mechanism 10 is maintained and the multiple second locking thread blocks 1005 are rotated, so that the second gasket 1004 is squeezed by the spiral, thereby completing the fixation of the overall clamping mechanism 10 on the clamping track mechanism 9, thereby completing the clamping and fixation of the special-shaped metal component at multiple clamping points.
