Technical Field
[0001] This application relates to the technical field of jigs, and in particular to a universal jig for an air tube. Background Technology
[0002] During the production of a car engine, various components need to be installed and tightened on the engine's air inlet pipe. During installation, a fixture is first used to fix the position of the air inlet pipe before the components are installed.
[0003] However, the specifications of the air inlet pipes connected to different engine models are also different. The fixtures currently used are usually designed according to the specifications of the air inlet pipes. As a result, one type of fixture can only limit the air inlet pipe of one specification. After the specifications of the air inlet pipe to be processed change, different fixtures need to be replaced, which makes the overall processing quite troublesome.
[0004] Therefore, a new technical solution is needed to address the above problems. Utility Model Content
[0005] In order to enable the fixture to clamp and position inflatable tubes of various sizes, this application provides a universal fixture for inflatable tubes.
[0006] This application provides a universal fixture for air inflators, which adopts the following technical solution: A universal fixture for inflatable tubes includes a fixed base, a shifting component disposed on the fixed base, and a clamping component for clamping the inflatable tube. The switching component includes a flip seat rotatably connected to a fixed base and several plug-in pins for limiting the position of the flip seat. The flip seat is provided with multiple support blocks that can support inflation tubes of different specifications. The flip seat is also provided with positioning holes corresponding to different support blocks. The plug-in pins can be inserted into the positioning holes to limit the support block corresponding to the positioning hole to face upward.
[0007] By adopting the above technical solution, the flip seat can be flipped so that different support blocks are set upwards, thereby supporting air tubes of different specifications. When adjusting the flip state of the flip seat, it is only necessary to insert the plug pin into the positioning hole to limit the position of the flip seat, making the adjustment of the flip seat more convenient.
[0008] Optionally: Each of the positioning holes is provided with a bushing, and the insertion pin is inserted into the corresponding bushing.
[0009] By adopting the above technical solution, the insertion pin can abut against the bushing, so that the insertion pin will not directly exert force on the flip seat and cause deformation of the positioning hole. The bushing can also be replaced after wear, thereby improving the service life of the flip seat.
[0010] Optionally, the clamping assembly includes an elbow clamp rotatably connected to a fixed base, a cylinder for driving the elbow clamp to rotate, and a pressure head disposed at one end of the elbow clamp, the lower end of the pressure head abutting against the upper end of the inflation tube.
[0011] By adopting the above technical solution, the cylinder drives the elbow clamp to rotate, so that the pressure head can abut against the top of the inflation tube, thereby limiting the position of the inflation tube.
[0012] Optionally: A first connecting rod is rotatably connected to the fixed base. The rotation point of the first connecting rod and the fixed base is located below the elbow clamp. The end of the first connecting rod away from the fixed base is located above the elbow clamp and rotatably connected to the output shaft of the cylinder. The cylinder body is rotatably connected to the fixed base. A second connecting rod is rotatably connected to the first connecting rod. The rotation point of the second connecting rod and the first connecting rod is located above the elbow clamp. The other end of the second connecting rod is rotatably connected to the elbow clamp. The rotation point of the second connecting rod and the elbow clamp is located on the side of the first connecting rod away from the cylinder.
[0013] By adopting the above technical solution, the force is transmitted through the first connecting rod and the second connecting rod, thereby increasing the torque by levering away from the cylinder, so that the cylinder at the pressure head can exert a greater force, and the inflation tube can be better compressed.
[0014] Optionally, a protective cover is also provided on the fixed base, and the protective cover is located outside the cylinder.
[0015] By adopting the above technical solution, the cylinder is not directly exposed to the outside, thus making it less likely for the cylinder to come into direct contact with the operator during operation, and thus less likely for the operator to be injured by the cylinder.
[0016] Optionally: The elbow clamp is provided with an adjusting component for adjusting the position of the pressure block. The adjusting component includes a threaded rod passing through the elbow clamp, two adjusting blocks sleeved on the threaded rod, and two adjusting nuts threadedly connected to the threaded rod. The pressure block is located at the lower end of the threaded rod. The adjusting blocks abut against the upper and lower end faces of the elbow clamp respectively. The adjusting nuts abut against the side walls of the two adjusting blocks that are far apart from each other. The elbow clamp is provided with an adjusting groove along its length, and the threaded rod can slide along the adjusting groove.
[0017] By adopting the above technical solution, the position of the pressure head can be adjusted after the specifications of the inflation tube change, so that the pressure head can be in contact with the correct position on the inflation tube, and the pressure head can press against inflation tubes of different specifications.
[0018] Optionally, the fixed base is further provided with a positioning component, the positioning component including a positioning seat disposed on the fixed base and a plurality of positioning pins disposed on the positioning seat, the positioning pins passing through the positioning seat and being able to abut against the end of the inflation tube.
[0019] By adopting the above technical solution, the positioning component is used to limit the position of the inflation tube on the support block, so that the support block can abut against the correct position on the inflation tube, making positioning more convenient during the placement of the inflation tube.
[0020] Optionally, the positioning seat is also provided with a detection sensor for detecting the presence or absence of an inflation tube, and the detection end of the detection sensor faces the inflation tube supported by the support block.
[0021] By adopting the above technical solution, after the detection sensor detects that the inflation tube is in place, the cylinder can be automatically controlled to position the inflation tube, eliminating the need for manual control of the cylinder and making the positioning and clamping process of the inflation tube more convenient.
[0022] Optionally, the flipping seat is also provided with a marking area corresponding to the support block.
[0023] By adopting the above technical solution, the specifications and models of the air tubes that the support block can support can be easily understood through the information on the marking area.
[0024] Optionally, the mounting base includes a horizontally arranged mounting plate and a support plate arranged around the outline of the mounting plate and located below the mounting plate, wherein the lower end of the support plate is lower than the lower end surface of the mounting plate.
[0025] By adopting the above technical solution, the lower end of the fixing base is set with an opening, so that sensor cables and the like are placed in the space at the lower end of the fixing base.
[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The flip seat can be flipped so that different support blocks are set upwards, thereby supporting air tubes of different specifications. When adjusting the flip seat's flip state, simply insert the plug pin into the positioning hole to limit the position of the flip seat, making the adjustment of the flip seat more convenient.
[0027] 2. After the specifications of the inflation tube change, the position of the pressure head can be adjusted so that the pressure head can be in the correct position on the inflation tube, so that the pressure head can press against the inflation tube of different specifications.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] This application discloses a universal fixture for inflatable tubes, such as... Figure 1 and Figure 2 As shown, the device includes a mounting base 1, a shifting assembly 2 mounted on the mounting base 1, and a clamping assembly 3 for clamping the inflation tube. The shifting assembly 2 is used to abut the lower end of the inflation tube, and the clamping assembly 3 clamps the inflation tube, thereby mounting components onto the inflation tube. The mounting base 1 includes a horizontally arranged mounting plate 11 and four support plates 12 arranged around the outline of the mounting plate 11. All four support plates 12 are fixed to the lower part of the mounting plate 11 by bolts. The two support plates 12 located on the long side of the mounting plate 11 are sheet metal parts, and the two support plates 12 located on the short side of the mounting plate 11 are aluminum profiles. The lower ends of all four mounting plates 11 are lower than the lower end surface of the mounting plate 11. L-shaped mounting seats 17 are provided on the sidewalls of the two aluminum profile mounting plates 11 that are far apart from each other. The lower end surface of the mounting seat 17 is flush with the lower end surface of the aluminum profile.
[0032] like Figure 3 and Figure 4As shown, the switching assembly 2 includes a flip seat 21 rotatably connected to the mounting plate 11 and several plug-in pins 22 for defining the position of the flip seat 21. Two flip fixing blocks 13 are also fixed to the upper end of the mounting plate 11 by screws. The two flip fixing blocks 13 are arranged along the length of the mounting plate 11 and are located on both sides of the flip seat 21. The two ends of the flip seat 21 are rotatably connected to the flip fixing blocks 11. The end of the flip seat 21 along its length is L-shaped, and the rotation axis of the flip seat 21 is located at the bend of the L-shape. Support blocks 23 of different shapes are respectively provided on the two bent sidewalls of the flip seat 21. In this embodiment, the support blocks 23 are made of polyurethane and can support inflation tubes of different specifications. Plug-in pins 22 pass through a flip fixing block 13 near the edge of the mounting plate 11, and the two plug-in pins 22 are respectively located on both sides of the rotation axis of the flip seat 21. Two positioning holes 211 are provided on the rotating base. The two positioning holes 211 are respectively located on both sides of the bend of the rotating base. A bushing 24 is respectively inserted into the two positioning holes 211. The insertion pin 22 can be inserted into the bushing 24 respectively, so that the support block 23 near the bushing 24 is set upward.
[0033] like Figure 3 As shown, each of the adjacent sidewalls of the flip base 21 is provided with an identification area 25. In this embodiment, the identification area 25 is set as a nameplate, which corresponds to the support base 15. Thus, the specification of the air tube that the support block 23 on the flip base 21 can be determined by the nameplate.
[0034] like Figure 3 and Figure 5As shown, the clamping assembly 3 is located on the side of the flipping fixing block 13 away from the flipping seat 21 where the insertion pin 22 is not provided. The clamping assembly 3 includes an elbow clamp 31 rotatably connected to the fixing seat 1, a cylinder 32 for driving the elbow clamp 31 to rotate, and a pressure head 33 located at one end of the elbow clamp 31. A lifting seat 14 is fixed to the mounting plate 11 by bolts, and a support seat 15 is fixed to the upper end of the lifting seat 14 by bolts. One end of the elbow clamp 31 is rotatably connected to the upper end of the support seat 15. The elbow clamp 31 is a long strip structure formed by bending. One open end of the elbow clamp 31 is respectively located on both sides of the support seat 15 and rotatably connected to the support seat 15. The other end of the elbow clamp 31 is provided with an adjustment assembly 4, and the pressure head 33 is located on the adjustment assembly 4 so that the position can be adjusted along the length direction of the elbow clamp 31. The adjustment assembly 4 includes a threaded rod 41 passing through the adjustment groove 311, two adjustment blocks 42 sleeved on the threaded rod 41, and two adjustment nuts 43 threadedly connected to the threaded rod 41. Two adjusting blocks 42 are respectively disposed on the upper and lower sides of the elbow clamp 31 and abut against the upper and lower sides of the elbow clamp 31. The two ends of the adjusting blocks 42 are also bent upward and abut against the side walls of the elbow clamp 31 away from the adjusting groove 311, so that the adjusting blocks 42 are not prone to rotation relative to the threaded rod 41. Two adjusting nuts 43 are respectively disposed on the side of the two adjusting blocks 42 that are far apart from each other, so that the adjusting blocks 42 are abutted against the elbow clamp 31 by adjusting the nuts 43. The lower end of the threaded rod 41 passes through the pressure head 33 and is threadedly engaged with the pressure head 33. In this embodiment, the pressure head 33 is made of polyurethane.
[0035] Cylinder 32 is located on the side of support base 15 away from shifting assembly 2. The cylinder body of cylinder 32 is rotatably connected to mounting plate 11. The piston rod of cylinder 32 is inclined upward and rotatably connected to a first connecting rod 34. The other end of the first connecting rod 34 is rotatably connected to support base 15, and the rotation axes of the two ends of the first connecting rod 34 are located on the upper and lower sides of elbow clamp 31, respectively. A second connecting rod 35 is also rotatably connected to the first connecting rod 34. The other end of the second connecting rod 35 is rotatably connected to elbow clamp 31. The connection point between the second connecting rod 35 and elbow clamp 31 is located on the side of the first connecting rod 34 near pressure head 33. The connection point between the second connecting rod 35 and the first connecting rod 34 is higher than elbow clamp 31 and lower than the position where the first connecting rod 34 is connected to cylinder 32.
[0036] like Figure 1 As shown, in order to prevent the operator from being injured by the cylinder 32 during operation, a protective cover 16 is also fixed to the mounting plate 11 by bolts. The protective cover 16 covers the cylinder 32 and has an opening on the side of the protective cover 16 near the shifting component 2.
[0037] like Figure 4As shown, the mounting plate 11 is also provided with a positioning assembly 5 for positioning the end of the inflation tube. The positioning assembly 5 includes a positioning seat 51 fixed to the mounting plate 11 by bolts and two positioning pins 52 passing through the positioning seat 51. The two positioning pins 52 are threadedly engaged with the mounting plate 11. The positioning plate can abut against the end of the inflation tube, and the positioning pins 52 can be inserted into the holes on the inflation tube, thereby limiting the position of the inflation tube.
[0038] The positioning plate is also equipped with a detection sensor 53 for detecting the presence or absence of the inflation tube. In this embodiment, a photoelectric sensor is selected. The detection sensor 53 is fixed to the side of the positioning seat 51 away from the switching component 2 by bolts. The detection end of the detection sensor 53 passes through the positioning seat 51 and is positioned towards the inflation tube on the switching component 2. The detection sensor 53 is electrically connected to the solenoid valve of the cylinder 32. When the detection sensor 53 detects the inflation tube, its detection sensor feedback signal is sent to the solenoid valve, thereby controlling the cylinder 32 to work so that the pressure head 33 presses the inflation tube tightly.
[0039] The implementation principle of this embodiment is as follows: the inflation tube is placed on the support block 23, and the inflation tube abuts against the positioning plate and the positioning pin 52 is inserted into the inflation tube. The detection sensor 53 detects the inflation tube. When the cylinder 32 is working, the pressure head 33 presses down to limit the position of the inflation tube. Then, the riser, pressure sensor and temperature sensor are manually installed on the inflation tube. After that, the completion switch is manually triggered to release the cylinder 32. Then the inflation tube is unloaded.
[0040] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
