Description

Technical Field

[0001] This invention relates to the field of fixture processing technology, and more specifically to a clamping device for fixture manufacturing. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection. It is also called a clamp. In a broader sense, any device used to quickly, conveniently and safely install a workpiece in any step of the process can be called a fixture.

[0003] During fixture manufacturing, a clamping device is needed to clamp and fix the clamping rods and clamping blocks.

The existing clamping device has a simple structure and cannot automatically feed the clamping rods and clamping blocks. At the same time, it cannot automatically splice the clamping blocks and clamping rods at any angle. It is necessary to manually adjust the angle between the clamping rods and clamping blocks before clamping and fixing, which makes the operation cumbersome and seriously affects the processing efficiency of the fixture.

[0021] The beneficial effects of this invention are:

[0022] (1) The clamping rods and clamping blocks that make up the fixture are automatically fed into the first mounting ring and the second mounting ring by the loading and unloading mechanism. The clamping and positioning mechanism in the first and second mounting rings is used to accurately clamp and position the clamping rods and clamping blocks. Then, by driving the second mounting ring to rotate, the clamping blocks are driven to rotate horizontally, so that the clamping blocks and clamping rods can be spliced ​​at any angle. After the splicing is completed, the spliced ​​clamping rods and clamping blocks are welded by the welding mechanism. After welding, they are placed on the loading and unloading mechanism for automatic unloading. This realizes the automatic loading of the clamping rods and clamping blocks of the fixture and the splicing and positioning of the loaded clamping rods and clamping blocks at any angle.

[0023] (2) According to the size of the clamping rod and clamping block, rotate the adjusting bolt 15 on the mounting column 14. Then the adjusting bolt 15 drives the clamping block 16 to move and adjust it to a suitable position. After the clamping rod and clamping block are sent into the third mounting ring and the second mounting ring, the drive mechanism drives the transmission ring to rotate. The transmission ring drives the transmission block and the mounting column to move through the transmission groove and the transmission column, so that the four clamping blocks move towards the middle of the mounting ring at the same time, and the clamping rod and clamping block are positioned and clamped to fix them. This makes them accurately fixed in the center position of the third mounting ring, which improves the accuracy of clamping and fixing the clamping rod. After the clamping and positioning are completed, the second transmission mechanism drives the second mounting ring to rotate. The second mounting ring drives the clamping block to rotate at any angle to the required angle. Then the first electric telescopic rod drives the third mounting ring and the clamping rod to move downward, so that the clamping block and the clamping rod are spliced ​​and positioned at any horizontal angle.

[0024] (3) After the clamping rod and clamping block are spliced ​​at any angle, the first mounting ring is driven to rotate by the first catalytic mechanism, thereby driving the spliced ​​clamping rod and clamping block to rotate, so that the spliced ​​joint is parallel to the mounting frame. Then, the spliced ​​contact is welded by the welding mechanism, thereby realizing the automatic welding and fixing of the clamping rod and clamping block at any angle in the vertical direction after positioning and fixing, which greatly improves the applicability of the clamping device to the welding and fixing of the clamping device.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see Figures 1-6 As shown, the present invention is a clamping device for manufacturing a fixture, including a mounting platform 1, a first mounting ring 2 fixedly and rotatably connected to the top of the mounting platform 1, a second mounting ring 3 rotatably connected to the top of the first mounting ring 2, a first electric telescopic rod 4 fixedly connected to the top of the second mounting ring 3, and a third mounting ring 5 fixedly connected to the top of the first electric telescopic rod 4 via a connecting block. Both the second mounting ring 3 and the third mounting ring 5 are provided with clamping and positioning mechanisms for positioning and clamping the fixture components. The outer surface of the first mounting ring 2 is driven by a first transmission mechanism connected to the mounting platform 1, which drives the first mounting ring 2 to rotate. The outer surface of the second mounting ring 3 is driven by a second transmission mechanism connected to the first mounting ring 2, which drives the third mounting ring 5 to rotate. A loading and unloading mechanism is provided below the mounting platform 1 for automatically loading fixture parts. A welding mechanism is provided on the mounting platform 1 for welding and fixing the clamped fixture.

[0036] The loading and unloading mechanism transports the transmission rod component of the clamp into the third mounting ring 5, where it is then clamped and fixed by the clamping and positioning mechanism. The first electric telescopic rod 4 then moves the third mounting ring 5 upwards, causing the clamping rod to move upwards as well. The loading and unloading mechanism then automatically loads the clamping block into the second mounting ring 3, where the clamping and positioning mechanism clamps and fixes the clamping block. Based on the angle between the clamping rod and the clamping block, the second transmission mechanism rotates the second mounting ring 3, causing the clamping block to rotate to the fixed connection angle. Finally, the first electric telescopic rod 4 moves the third mounting ring 5 downwards, bringing the clamping rod and clamping block into contact, thus achieving proper clamping of the clamping rod and clamping block. The clamping blocks are clamped and fixed at any angle. Then, the first transmission mechanism drives the first mounting ring 2 to rotate. The first mounting ring 2 drives the second mounting ring 3, the first electric telescopic rod 4, and the third mounting ring 5 to rotate, thereby driving the clamping rod and clamping block, which are automatically positioned, to rotate to the position of the welding mechanism. Then, they are parallel to the welding mechanism, and the welding mechanism welds and fixes them. After welding, the welded fixture is placed on the loading and unloading mechanism for conveying. This realizes the automatic loading of the clamping rod and clamping block, the automatic positioning and fixing of the clamping rod and clamping block at any angle, and the angle adjustment of the fixed clamping rod and clamping block for welding and fixing. This greatly improves the automation level of fixture production and further improves the welding efficiency of fixtures.

[0037] Example 2

[0038] Based on Example 1, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, the clamping and positioning mechanism includes functional cavities 11 on both the first mounting ring 2 and the third mounting ring 5. A transmission ring 12 is rotatably connected within each functional cavity 11. Multiple transmission blocks 13 are slidably connected within the functional cavity 11. A mounting post 14 is fixedly connected to one side of each transmission block 13. An adjusting bolt 15 is threadedly connected to one side of the mounting post 14. A clamping block 16 is fixedly connected to one end of the adjusting bolt 15. Multiple transmission grooves 17 are formed on the outer surface of the transmission ring 12. A transmission post 18, slidably connected to the transmission groove 17, is fixedly connected to one side of each transmission block 13. A drive mechanism connected to the functional cavity 11 is drively connected to the outer surface of the transmission ring 12. The drive mechanism is used to drive... The drive ring 12 rotates. The drive mechanism includes a drive motor 21 fixedly connected to the functional cavity 11. The drive motor 21 is controlled by a PLC programming program, which can control the forward and reverse rotation and the rotation angle of the drive motor 21. The output end of the drive motor 21 is fixedly connected to a drive shaft 22 via a coupling. A first drive gear 23 is fixedly sleeved on the outer surface of the drive shaft 22. A second drive gear 24, which is fixedly sleeved on the outer surface of the first drive gear 23, is meshed with the drive ring 12. The drive motor 21 drives the drive shaft 22 to rotate, and the drive shaft 22 drives the drive ring 12 to rotate via the first drive gear 23 and the second drive gear 24.

[0039] The first transmission mechanism includes a first motor 41 fixedly connected to the mounting platform 1. The first motor 41 is controlled by a PLC programming program, which can control the first motor 41 to rotate forward and backward and rotate at different angles. The output end of the first motor 41 is fixedly connected to a first rotating shaft 42 through a coupling. A first gear 43 is fixedly sleeved on the outer surface of the first rotating shaft 42. A second gear 44 is meshed with the outer surface of the first gear 43 and is fixedly sleeved on the first mounting ring 2.

[0040] The first motor 41 drives the first rotating shaft 42 to rotate, and the first rotating shaft 42 drives the first mounting ring 2 to rotate through the first gear 43 and the second gear 44.

[0041] The second transmission mechanism includes a second motor 51 fixedly connected to the second mounting ring 3. The second motor 51 is controlled by a PLC programming program, which can control the forward and reverse rotation and rotation angle of the second motor 51. The output end of the second motor 51 is fixedly connected to a second rotating shaft 52 through a coupling. A third gear 53 is fixedly sleeved on the outer surface of the second rotating shaft 52. A fourth gear 54, which is fixedly sleeved on the outer surface of the third gear 53, is fixedly sleeved on the second mounting ring 3.

[0042] The second motor 51 drives the second rotating shaft 52 to rotate, and the second rotating shaft 52 drives the second mounting ring 3 to rotate through the third gear 53 and the fourth gear 54.

[0043] Based on the size of the clamping rod and clamping block, rotate the adjusting bolt 15 on the mounting column 14. The adjusting bolt 15 then moves the clamping block 16 to a suitable position. The first electric telescopic rod 4 moves the third mounting ring 5 downwards. The loading / unloading mechanism then loads the clamping rod into the third mounting ring 5. The drive mechanism then rotates the transmission ring 12, which moves the transmission column 18 via the transmission groove 17. The transmission column 18 moves the transmission block 13, which in turn moves the mounting column 14 and the adjusting bolt 15. The adjusting bolt 15 moves the clamping block 16, causing all four clamping blocks 16 to move towards the center simultaneously, positioning and clamping the clamping rod precisely within the third mounting ring 5. The central position of the clamping block improves the accuracy of clamping and fixing the clamping rod. Then, the loading and unloading mechanism feeds the clamping block into the second mounting ring 3. This causes the four clamping blocks 16 within the second mounting ring 3 to move towards the center, clamping and fixing the clamping block, thus achieving precise positioning and clamping. After clamping, the second transmission mechanism drives the second mounting ring 3 to rotate, causing the clamping block to rotate to a fixed position, achieving precise angular positioning of the clamping block. Then, the first electric telescopic rod 4 drives the third mounting ring 5 to move downwards, causing the clamping rod to move downwards and fit snugly against the clamping block. Finally, the first transmission mechanism drives the first mounting ring 2 to rotate, causing the positioned and fixed fixture to rotate to the welding position for welding and fixing. This achieves automatic feeding of the clamping block and clamping rod on the fixture, precise positioning of the fed clamping block and clamping rod, and precise adjustment of any angle between them, achieving fixation of the clamping block and clamping rod at any angle on the fixture.

[0044] Example 3

[0045] Based on Example 2, please refer to Figure 1 , Figure 2 and Figure 5 As shown, the loading and unloading mechanism includes a belt conveyor 31, a plurality of sliding columns 32 are fixedly connected to the belt conveyor 31, an mounting plate 33 is slidably connected to the sliding columns 32, a support column 34 is fixedly connected to the top of the mounting plate 33, a feeding permanent magnet plate 35 is fixedly connected to the top of the support column 34, two connecting plates 36 are fixedly connected to the mounting platform 1, a second electric telescopic rod 37 is fixedly connected to the connecting plate 36, and an electromagnet push plate 38 is fixedly connected to the top of the second electric telescopic rod 37.

[0046] The clamping block is placed onto the feeding permanent magnet plate 35 on the short support column 34 for adsorption and fixation. Then, the clamping rod is placed onto the feeding permanent magnet plate 35 on the long support column 34 for adsorption and fixation. It is then transported by the belt conveyor 31. When the clamping rod is transported to the bottom of the second mounting ring 3, the second electric telescopic rod 37 drives the electromagnet push plate 38 to move downward. At the same time, the electromagnet push plate 38 is energized to adsorb and fix the mounting plate 33. The mounting plate 33 is made of iron. Then, the mounting plate 33 is moved upward. The mounting plate 33 drives the support column 34 and the feeding permanent magnet plate 35 to move upward, pushing the clamping rod upward. Then, the clamping and positioning mechanism clamps and fixes the clamping rod. Then, the second electric telescopic rod 37 drives the mounting plate 33 to move downward through the electromagnet push plate 38. At this time, the attraction force of the feeding permanent magnet plate 35 on the clamping rod is less than the pulling force of the second electric telescopic rod 37, causing the clamping rod to disengage. The same applies to the feeding of the clamping block, thereby realizing the automatic feeding of the clamping rod and the clamping block.

[0047] The welding mechanism includes a third electric telescopic rod 61 fixedly connected to the mounting platform 1. One end of the third electric telescopic rod 61 is fixedly connected to an adjusting block 62 slidably connected to the mounting platform 1. A fourth electric telescopic rod 63 is fixedly connected to the top of the adjusting block 62. A mounting frame 64 is fixedly connected to the top of the fourth electric telescopic rod 63. A slider 65 is slidably connected inside the mounting frame 64. A welding head 66 is fixedly connected to one side of the slider 65. The slider 65 is connected to a moving mechanism connected to the mounting frame 64. The moving mechanism is used to drive the slider 65 to move. The moving mechanism includes a third motor 67 fixedly connected to the mounting frame 64. The output end of the third motor 67 is fixedly connected to a threaded rod 68 rotatably connected to the mounting frame 64 via a coupling. The threaded rod 68 is threadedly connected to the slider 65.

[0048] After the clamping rod and clamping block are clamped and fixed, the clamping fixture after positioning and fixing is rotated so that the connection seam between the clamping rod and clamping block is parallel to the mounting frame 64. Then, the third electric telescopic rod 61 drives the adjusting block 62 to move, and the fourth electric telescopic rod 63 drives the mounting frame 64 to move, so that the welding head 66 on the mounting frame 64 abuts against the connection seam. Then, the third motor 67 drives the threaded rod 68 to rotate, the threaded rod 68 drives the slider 65 to move, and the slider 65 drives the welding head 66 to move. Then, the welding head 66 welds the connection, thereby realizing the automatic welding and fixing of the clamping rod and clamping block at any angle in the vertical direction after positioning and fixing, which greatly improves the applicability of the welding and fixing of the clamping fixture. When the welding is completed, the clamping and positioning mechanism in the second mounting ring 3 no longer clamps the clamping block. Then, the first electric telescopic rod 4 drives the third mounting ring 5 to move downward, unloading the welded clamping fixture onto the feeding permanent magnet plate 35 for conveying out, realizing the automatic unloading of the welded clamping fixture.

[0049] The working principle of this invention is as follows: The loading and unloading mechanism transports the transmission rod component of the clamp into the third mounting ring 5. Then, the clamping and positioning mechanism within the third mounting ring 5 clamps and fixes it. Next, the first electric telescopic rod 4 drives the third mounting ring 5 upward, causing the clamping rod to move upward. Then, the loading and unloading mechanism automatically loads the clamping block into the second mounting ring 3. The clamping and positioning mechanism within the second mounting ring 3 clamps and fixes the clamping block. Then, based on the connection angle between the clamping rod and the clamping block, the second transmission mechanism drives the second mounting ring 3 to rotate. The second mounting ring 3 drives the clamping block to rotate, causing the clamping block to rotate to the fixed connection angle. Finally, the first electric telescopic rod 4 drives the third mounting ring 5 downward, causing the clamping rod and clamping block to fit together. The clamping rod and clamping block are clamped and fixed at any angle. Then, the first transmission mechanism drives the first mounting ring 2 to rotate. The first mounting ring 2 drives the second mounting ring 3, the first electric telescopic rod 4, and the third mounting ring 5 to rotate, thereby driving the clamping rod and clamping block, which are automatically positioned, to rotate to the position of the welding mechanism. Then, they are parallel to the welding mechanism, and the welding mechanism welds and fixes them. After welding, the welded fixture is placed on the loading and unloading mechanism for conveying. This realizes the automatic loading of the clamping rod and clamping block, the automatic positioning and fixing of the clamping rod and clamping block at any angle, and the angle adjustment of the fixed clamping rod and clamping block for welding and fixing. This greatly improves the automation level of fixture production and further improves the welding efficiency of fixtures.

[0050] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
