Description

Technical Field

[0001] The invention belongs to the technical field of pipe processing tooling, and particularly relates to a pipe bending processing tooling for fitness equipment. Background Art

[0002] The bent pipes of fitness equipment are tubular components processed by bending technology in fitness equipment and are widely used in various fitness equipment. Different shapes and angle designs of the bent pipes of fitness equipment are to meet various specific exercise requirements. For example, the arm bent pipe of an elliptical machine is designed according to the trajectory of the natural swing of the arm and the comfortable holding posture during human movement, which can keep the user balanced and comfortable during exercise and increase the smoothness of exercise. The bent pipe also plays a role in connecting and supporting in fitness equipment, which can enhance the overall stability and structural strength of the equipment. For example, the support bent pipe of a squat rack, through reasonable bending shape and structural design, firmly connects each part of the squat rack together, so that the squat rack can still maintain stability when bearing the weight of the human body and the barbell, ensuring the safety of the user.

[0003] The existing bent pipes need to be combined by welding after being bent by a pipe bender. However, due to the relatively variable bending shapes, it is difficult for traditional jigs to clamp the bent pipes, while the specially customized jigs have high costs and narrow application ranges, and can only fix the bent pipes, which is not convenient for workers to perform welding operations. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a pipe bending processing tooling for fitness equipment.

[0005] The technical solution adopted to solve the above technical problem is: a pipe bending processing tooling for fitness equipment, including a bottom plate, a driving mechanism is fixedly connected to the upper surface of the bottom plate, a pair of first connecting rods are rotatably connected to one end of the upper surface of the bottom plate, a tooling table is rotatably connected to the end of the first connecting rod away from the bottom plate, a plurality of fixed bases are fixedly connected to the tooling table, and a fixture mechanism is arranged in the fixed base;

[0006] The fixture mechanism includes a connecting sleeve, a fixture table is fixedly connected to the connecting sleeve, an inclined rack is slidably connected in the fixture table, an inclined gear is movably connected in the fixture table, the inclined gear and the inclined rack are meshed and matched with each other, a rotating rod is fixedly connected to the upper surface of the inclined gear, a first sliding groove and a second sliding groove are formed in the rotating rod, a second bolt is threadedly connected through the fixture table, and the second bolt is slidably matched with the first sliding groove and the second sliding groove.

[0007] Through the above technical solution, by using the second bolt on the fixture mechanism, the second bolt drives the adjustable support plate to move up and down, so as to adapt to bent pipes with different diameters. By using the helical gear and the helical rack, the rotating pressure bar can be pressed down after rotation. The rotating pressure bar cooperates with the adjustable support plate to clamp the bent pipe. When the rotating pressure bar is released, it can move up first and then rotate, so as to avoid interference with the bent pipe.

[0008] Further, a positioning pin is fixedly connected to one end of the connecting sleeve close to the fixture table. An inclined groove is opened in the connecting sleeve. One end of the helical rack is rotatably connected to a second lead screw. The end of the second lead screw far from the helical rack is fixedly connected with an internal hexagonal interface. The second lead screw penetrates and is threadedly connected to the fixture table. Second grooves are opened on both sides of the helical rack. A pair of limiting convex blocks are fixedly connected in the fixture table. The internal hexagonal interface and the second grooves are slidably matched with each other.

[0009] Through the above technical solution, the second lead screw drives the helical rack to move along the limiting convex blocks. At this time, since the second bolt slides in the second chute, the rotating rod can only rotate, so that the helical rack drives the helical gear to rotate, and the helical gear drives the rotating rod to rotate.

[0010] Further, the lower end of the first chute is communicated with the second chute. The upper end of the rotating rod is fixedly connected with a rotating pressure bar. An anti-slip rubber pad is fixedly connected to the lower surface of the end of the rotating pressure bar far from the rotating rod. A pair of first bolts penetrate and are threadedly connected to the fixture table.

[0011] Through the above technical solution, the rotating rod drives the rotating pressure bar to rotate, so that the rotating pressure bar drives the anti-slip rubber pad to move above the bent pipe. Then the second bolt enters the first chute, so that the rotating rod can only move up and down and cannot rotate. At this time, the helical rack pushes the helical gear to move down through the helical teeth, so that the helical gear drives the rotating pressure bar to move down through the rotating rod, and the rotating pressure bar cooperates with the adjustable support plate to clamp the bent pipe.

[0012] Further, a limiting ring is fixedly connected to the upper ends of the pair of first bolts. An adjustable support plate is arranged on the upper surface of the fixture table. Second through holes are opened at both ends of the adjustable support plate. Limiting grooves are opened on the inner wall of the second through holes. The limiting grooves and the limiting rings are slidably matched with each other. The first bolts penetrate the second through holes.

[0013] Through the above technical solution, by rotating the first bolt with a hexagon wrench, the first bolt drives the adjustable support plate to move up and down through the cooperation of the limiting ring and the limiting groove, so as to adapt to bent pipes with different diameters.

[0014] Further, the tooling table includes a housing rotatably connected to a first connecting rod. A hydraulic rod penetrates and is fixedly connected to the housing. The output end of the hydraulic rod is fixedly connected with a connecting frame.

[0015] Through the above technical solution, the hydraulic rod drives the connecting frame to move, and the connecting frame drives the third connecting rod to move, so that the fixture mechanism can be locked on the fixed base.

[0016] Further, the fixed base includes a fixed sleeve fixedly connected to the outer shell. A third connecting rod is slidably connected through the fixed sleeve. The third connecting rod is fixedly connected to the connecting frame. A conical expansion head is fixedly connected to one end of the third connecting rod away from the connecting frame. A first groove is formed at one end of the conical expansion head away from the third connecting rod. The positioning pin is slidably connected through the first groove.

[0017] Through the above technical solution, the positioning pin is inserted into the first groove for positioning, and the angle of the fixture mechanism is adjusted. Then the connecting sleeve is inserted into the fixed sleeve. Subsequently, the hydraulic rod drives the connecting frame to move, and the connecting frame drives the third connecting rod to move. The conical expansion head on the third connecting rod squeezes and expands the second connecting rod outwards, so that the wedge block on the second connecting rod squeezes and hooks the inclined groove, and the fixture mechanism is fixed in the fixed base.

[0018] Further, a first through hole is formed at the bottom of the fixed sleeve. A second connecting rod is connected through the first through hole. Fixed shafts are fixedly connected to both sides of the second connecting rod. A wedge block is fixedly connected to one end of the second connecting rod close to the conical expansion head. A rocker is fixedly connected to one end of the second connecting rod away from the wedge block. The wedge block and the inclined groove are engaged with each other. A convex ring is fixedly connected to one end of the third connecting rod away from the conical expansion head.

[0019] Through the above technical solution, when the fixture mechanism needs to be disassembled, only need to push the connecting frame to move through the hydraulic rod. The connecting frame drives the third connecting rod to move. The convex ring on the third connecting rod cooperates with the rocker to drive the second connecting rod to rotate along the fixed shaft, so that the wedge block disengages from the inclined groove, and thus the fixture mechanism can be taken out.

[0020] Further, the driving mechanism includes a fixed frame fixedly connected to the upper surface of the bottom plate. A driving motor is fixedly connected to the fixed frame. A driving roller is fixedly connected to the output end of the driving motor. A pair of belts are sleeved on the driving roller. A pair of first lead screws are rotatably connected to the upper surface of the bottom plate. A driven roller is sleeved inside each end of the pair of belts away from the driving roller. The driven roller is fixedly connected to the first lead screw. A pair of slide rails are fixedly connected to the upper surface of the bottom plate. A moving frame is slidably connected to each of the pair of slide rails. The moving frame is rotatably connected to the tooling table. The first lead screw penetrates and is threadedly connected to the moving frame.

[0021] Through the above technical solution, the driving motor drives the driving roller, the driving roller drives the driven roller to rotate through the belt, the driven roller drives the first lead screw to rotate, the first lead screw drives the moving frame to move, and the moving frame drives one end of the tooling table to move. Since the first connecting rod is connected to the tooling table, the tooling table can be arbitrarily converted between horizontal and vertical under the drive of the moving frame 28, greatly improving the processing convenience.

[0022] The beneficial effects of the present invention are as follows: (1) By setting a driving mechanism on the bottom plate of the present invention, the driving motor drives the first lead screw to rotate, and the first lead screw drives the moving frame to move along the slide rail, so that the tooling table can be converted between vertical and horizontal under the limitation of the first connecting rod, so that the tooling table can drive the bent pipe to move to a predetermined angle, thus facilitating the welding process of the bent pipe; (2) By setting a plurality of fixed bases on the tooling table of the present invention, through the cooperation of the fixed bases and the fixture mechanism, the fixture mechanism can be set at different positions on the tooling table according to needs, making the fixture mechanism more suitable for bent pipes at different angles, thereby improving the clamping stability; (3) By using the second bolt on the fixture mechanism of the present invention, the second bolt drives the adjustable support plate to move up and down, so as to adapt to bent pipes of different diameters. By using the helical gear and the helical rack, the rotating pressure rod can be pressed down after rotation, and the rotating pressure rod and the adjustable support plate cooperate to clamp the bent pipe. When the rotating pressure rod is released, it can first move up and then rotate, thus avoiding interference with the bent pipe. Brief Description of the Drawings

Detailed implementation manners

[0036] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] As Figures 1 - 12 shown, a pipe bending processing tooling for fitness equipment in this embodiment, a pipe bending processing tooling for fitness equipment, includes a bottom plate 1. One end of the upper surface of the bottom plate 1 is rotatably connected with a pair of first connecting rods 3. A fixture mechanism 6 is arranged in a fixed base 5. By arranging a plurality of fixed bases 5 on the tooling table 4 and through the cooperation of the fixed base 5 and the fixture mechanism 6, the fixture mechanism 6 can be arranged at different positions on the tooling table 4 according to requirements, so that the fixture mechanism 6 is more suitable for pipes at different angles, thereby improving the clamping stability.

[0038] The fixture mechanism 6 includes a connecting sleeve 61. A fixture table 62 is fixedly connected to the connecting sleeve 61. An inclined rack 67 is slidably connected inside the fixture table 62. An inclined gear 69 is movably connected inside the fixture table 62. The inclined gear 69 and the inclined rack 67 are meshed and matched with each other. A rotating rod 610 is fixedly connected to the upper surface of the inclined gear 69. A first chute 611 and a second chute 612 are formed in the rotating rod 610. A second bolt 621 is threadedly connected through the fixture table 62. The second bolt 621 is slidably matched with the first chute 611 and the second chute 612. By driving the internal hexagonal interface 65 to rotate with a hexagonal wrench, the second screw rod 66 is driven to rotate by the internal hexagonal interface 65. The second screw rod 66 drives the inclined rack 67 to move along the limiting lug 615. At this time, since the second bolt 621 slides in the second chute 612, the rotating rod 610 can only rotate. Thus, the inclined rack 67 drives the inclined gear 69 to rotate. The inclined gear 69 drives the rotating pressure rod 613 to rotate through the rotating rod 610, so that the rotating pressure rod 613 drives the anti-slip rubber pad 614 to move above the bent pipe. Then, the second bolt 621 enters the first chute 611, making the rotating rod 610 can only move up and down and cannot rotate. At this time, the inclined rack 67 pushes the inclined gear 69 to move downward through the helical teeth. Thus, the inclined gear 69 drives the rotating pressure rod 613 to move downward through the rotating rod 610, so that the rotating pressure rod 613 cooperates with the adjustable support plate 616 to clamp the bent pipe. Since the rotating pressure rod 613 is only above the adjustable support plate 616 when clamping the bent pipe, when the rotating pressure rod 613 does not clamp the bent pipe, it will not interfere with the bent pipe. Thus, the flexibility of the bent pipe processing is greatly improved.

[0039] A positioning pin 63 is fixedly connected to one end of the connecting sleeve 61 close to the fixture table 62. An inclined slot 64 is formed in the connecting sleeve 61. One end of the inclined rack 67 is rotatably connected to a second screw rod 66. The end of the second screw rod 66 away from the inclined rack 67 is fixedly connected to an internal hexagonal interface 65. The second screw rod 66 is threadedly connected through the fixture table 62. Second grooves 68 are formed on both sides of the inclined rack 67. A pair of limiting lugs 615 are fixedly connected inside the fixture table 62. The internal hexagonal interface 65 and the second grooves 68 are slidably matched. The positioning pin 63 is inserted into the first groove 59 for positioning, and the angle of the fixture mechanism 6 is adjusted. The connecting sleeve 61 is inserted into the fixed sleeve 51. [[ID=…]]

[0040] The lower end of the first chute 611 is communicated with the second chute 612. A rotating pressure rod 613 is fixedly connected to the upper end of the rotating rod 610. An anti-slip rubber pad 614 is fixedly connected to the lower surface of the end of the rotating pressure rod 613 away from the rotating rod 610. A pair of first bolts 619 are threadedly connected through the fixture table 62. The rotating pressure rod 613 drives the anti-slip rubber pad 614 to move downward to cooperate with the adjustable support plate 616 to clamp the bent pipe.

[0041] The upper ends of a pair of first bolts 619 are fixedly connected with a limit ring 620. An adjustable support plate 616 is arranged on the upper surface of the fixture table 62. Second through holes 617 are formed at both ends of the adjustable support plate 616. Limit grooves 618 are formed on the inner walls of the second through holes 617. The limit grooves 618 and the limit ring 620 are slidably matched with each other. The first bolt 619 passes through the second through hole 617. The first bolt 619 drives the adjustable support plate 616 to move up and down through the cooperation of the limit ring 620 and the limit groove 618, so as to adapt to bent pipes with different diameters. Then, the bent pipe is placed on the adjustable support plate 616.

[0042] As Figure 2 shown, a driving mechanism 2 is fixedly connected to the upper surface of the bottom plate 1. The driving mechanism 2 includes a fixing frame 21 fixedly connected to the upper surface of the bottom plate 1. A driving motor 22 is fixedly connected to the fixing frame 21. The output end of the driving motor 22 is fixedly connected with a driving roller 23. A pair of belts 25 are sleeved on the driving roller 23. A pair of first lead screws 26 are rotatably connected to the upper surface of the bottom plate 1. Driven rollers 27 are sleeved inside the ends of the pair of belts 25 away from the driving roller 23. The driven rollers 27 are fixedly connected with the first lead screws 26. A pair of slide rails 24 are fixedly connected to the upper surface of the bottom plate 1. A moving frame 28 is slidably connected to each of the pair of slide rails 24. The moving frame 28 is rotatably connected to the tooling table 4. The first lead screw 26 passes through and is threadedly connected to the moving frame 28. The driving motor 22 drives the driving roller 23. The driving roller 23 drives the driven roller 27 to rotate through the belt 25. The driven roller 27 drives the first lead screw 26 to rotate. The first lead screw 26 drives the moving frame 28 to move. The moving frame 28 drives one end of the tooling table 4 to move. Since the first connecting rod 3 is connected to the tooling table 4, the tooling table 4 can be arbitrarily switched between horizontal and vertical directions under the drive of the moving frame 28, greatly improving the processing convenience.

[0043] As Figure 4 and Figure 5 shown, one end of the first connecting rod 3 away from the bottom plate 1 is rotatably connected to a tooling table 4. The tooling table 4 includes a housing 41 rotatably connected to the first connecting rod 3. A hydraulic rod 42 is fixedly connected through the housing 41. The output end of the hydraulic rod 42 is fixedly connected with a connecting frame 43. The hydraulic rod 42 drives the connecting frame 43 to move. The connecting frame 43 drives the third connecting rod 57 to move, so as to control the locking and unlocking of the fixture mechanism 6.

[0044] As Figures 6 - 8As shown, several fixed bases 5 are fixedly connected to the tooling table 4. The fixed base 5 includes a fixed sleeve 51 fixedly connected to the outer shell 41. A third connecting rod 57 is slidably connected through the fixed sleeve 51. The third connecting rod 57 is fixedly connected to the connecting frame 43. One end of the third connecting rod 57 away from the connecting frame 43 is fixedly connected to a conical expansion head 58. A first groove 59 is formed at one end of the conical expansion head 58 away from the third connecting rod 57. A positioning pin 63 is slidably connected through the first groove 59. The connecting frame 43 drives the third connecting rod 57 to move. The conical expansion head 58 on the third connecting rod 57 squeezes and expands the second connecting rod 53 outward, so that the wedge block 55 on the second connecting rod 53 squeezes and hooks the inclined groove 64, and the fixture mechanism 6 is fixed in the fixed base 5.

[0045] A first through hole 52 is formed at the bottom of the fixed sleeve 51. A second connecting rod 53 is connected through the first through hole 52. Fixed shafts 54 are fixedly connected to both sides of the second connecting rod 53. One end of the second connecting rod 53 close to the conical expansion head 58 is fixedly connected to a wedge block 55. One end of the second connecting rod 53 away from the wedge block 55 is fixedly connected to a rocker 56. The wedge block 55 and the inclined groove 64 are engaged with each other. A convex ring 510 is fixedly connected to one end of the third connecting rod 57 away from the conical expansion head 58. The hydraulic rod 42 is used to drive the connecting frame 43 to move. The connecting frame 43 drives the third connecting rod 57 to move. The convex ring 510 on the third connecting rod 57 cooperates with the rocker 56 to drive the second connecting rod 53 to rotate along the fixed shaft 54, so that the wedge block 55 is disengaged from the inclined groove 64, and thus the fixture mechanism 6 can be taken out.

[0046] The working principle of this embodiment is as follows. The worker places several fixture mechanisms 6 in the fixed base 5 according to the predetermined bent pipe shape, inserts the positioning pin 63 into the first groove 59 for positioning, and adjusts the angle of the fixture mechanism 6. The connecting sleeve 61 is inserted into the fixed sleeve 51. Subsequently, the hydraulic rod 42 drives the connecting frame 43 to move. The connecting frame 43 drives the third connecting rod 57 to move. The conical expansion head 58 on the third connecting rod 57 squeezes and expands the second connecting rod 53 outward, so that the wedge block 55 on the second connecting rod 53 squeezes and hooks the inclined groove 64, and the fixture mechanism 6 is fixed in the fixed base 5.

[0047] After that, turn the first bolt 619 with a hexagonal wrench. The first bolt 619 drives the adjustable support plate 616 to move up and down through the cooperation of the limit ring 620 and the limit groove 618, so as to adapt to bent pipes with different diameters. Then, place the bent pipe on the adjustable support plate 616, drive the internal hexagonal interface 65 to rotate with the hexagonal wrench, the internal hexagonal interface 65 drives the second lead screw 66 to rotate, and the second lead screw 66 drives the inclined rack 67 to move along the limit projection 615. At this time, since the second bolt 621 slides in the second chute 612, the rotating rod 610 can only rotate, so that the inclined rack 67 drives the helical gear 69 to rotate. The helical gear 69 drives the rotating pressure rod 613 to rotate through the rotating rod 610, so that the rotating pressure rod 613 drives the anti-slip rubber pad 614 to move above the bent pipe. After that, the second bolt 621 enters the first chute 611, so that the rotating rod 610 can only move up and down and cannot rotate. At this time, the inclined rack 67 pushes the helical gear 69 to move down through the helical teeth, so that the helical gear 69 drives the rotating pressure rod 613 to move down through the rotating rod 610, and the rotating pressure rod 613 cooperates with the adjustable support plate 616 to clamp the bent pipe. Since the rotating pressure rod 613 is only above the adjustable support plate 616 when clamping the bent pipe, when the rotating pressure rod 613 does not clamp the bent pipe, it will not interfere with the bent pipe, thus greatly improving the flexibility of bent pipe processing.

[0048] When it is necessary to process other angles of the bent pipe, the driving motor 22 can be started. The driving motor 22 drives the driving roller 23, the driving roller 23 drives the driven roller 27 to rotate through the belt 25, the driven roller 27 drives the first lead screw 26 to rotate, the first lead screw 26 drives the moving frame 28 to move, and the moving frame 28 drives one end of the tooling table 4 to move. Since the tooling table 4 is connected with the first connecting rod 3, the tooling table 4 can be arbitrarily switched between horizontal and vertical under the drive of the moving frame 28, greatly improving the processing convenience.

[0049] When it is necessary to disassemble the fixture mechanism 6, only need to push the connecting frame 43 to move through the hydraulic rod 42. The connecting frame 43 drives the third connecting rod 57 to move. The convex ring 510 on the third connecting rod 57 cooperates with the rocker 56 to drive the second connecting rod 53 to rotate along the fixed shaft 54, so that the wedge block 55 disengages from the inclined groove 64, and thus the fixture mechanism 6 can be taken out.

[0050] The above is only a preferred embodiment of the present invention and is not used to limit the protection scope of the present invention.
