Description

Technical Field

[0001] This utility model belongs to the field of automotive parts assembly technology, and specifically relates to an automotive pipe bending assembly fixture. Background Technology

[0002] Automotive pipe bending assembly is an important part of the automobile manufacturing process. It involves correctly installing metal or plastic pipes of various shapes and sizes into the corresponding positions on the vehicle. These pipes are used to transport liquids (such as coolant and brake fluid), gases (such as fuel vapor and air), or as structural support components. Automotive pipe bending assembly fixtures are required to clamp and fix the automotive pipes to be assembled.

[0003] Existing automotive pipe bending assembly fixtures work by placing the automotive pipes to be clamped in a suitable position, then driving the clamping module with a motor to bring the movable jaws or pressure plates close to the pipes. The electronic control module then activates, causing the clamped pipes to move towards each other for assembly. However, in actual use, because the bending direction of the pipes varies at different locations, manual adjustment of the pipe placement and clamping positions is required to meet different assembly needs. In mass production of automotive pipes, frequent manual adjustment of the clamping positions on both sides places a significant workload for the machining personnel. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an automotive bending pipe assembly fixture, which can quickly and stably adjust the clamping state of the automotive bending pipes to be assembled on both sides during the assembly of automotive bending pipes, reducing the workload of personnel and facilitating use.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an automotive pipe bending assembly fixture, including a tooling table, an assembly seat on the upper surface of the tooling table, symmetrically distributed guide rails on the upper surface of the assembly seat, sliding seats slidably mounted on the guide rails, a clamping seat rotatably mounted in the middle of the sliding seat via a rotating shaft, a placement groove on the upper surface of the clamping seat, gears fixedly mounted on the outer arc surface of the rotating shaft, symmetrically distributed slide rails inside the sliding seat, sliders slidably mounted on the outer side of the slide rails, a rack plate on the side of the slider near the gear, and the rack plate meshing with adjacent gears respectively; an mounting frame on the upper surface of the clamping seat, a sliding plate slidably mounted on the lower side of the mounting frame, a clamping block on the lower surface of the sliding plate, an electric push rod II on the upper end of the mounting frame, the telescopic ends of the electric push rod II being connected and fixed to adjacent sliding plates respectively; symmetrically distributed supports on the upper surface of the tooling table, an electric push rod I on each support, the telescopic ends of the electric push rod I being connected and fixed to adjacent sliding seats respectively.

[0006] As a further improvement of this utility model, each of the sliding seats is provided with symmetrically distributed electric push rods three, and the telescopic ends of the electric push rods three are respectively connected and fixed to the adjacent sliders; a control board is provided on the front side of the assembly seat, and electric push rods one, two and three are all electrically connected to the control board.

[0007] As a further improvement of this utility model, the front side of the tooling table is provided with a sliding door that is staggered front and back, and each sliding door is provided with a handle on the front side. The lower surface of the tooling table is provided with evenly distributed support legs.

[0008] As a further improvement of this utility model, the interior of the placement groove is provided with evenly distributed rubber columns by glue, and the lower surface of the pressing block is fixed with a rubber plate by glue.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the operation of the electric push rod 2 is controlled by the control panel, so that the telescopic end of the electric push rod 2 drives the slide plate to move vertically downward, thereby driving the clamping block to press down and quickly and stably clamp and fix the automotive bend pipe that needs to be assembled.

[0011] Secondly, the control panel regulates the operation of the three electric push rods, which drive the gears to rotate through the meshing relationship between the rack plate and the gears, thereby causing the gears on the left and right sides to rotate. This causes the gears to drive the clamping seat to rotate through the rotating shaft, so that the positions of the bent tubes on the left and right sides correspond.

[0012] Third, the control panel regulates the operation of the electric push rod, causing the telescopic end of the electric push rod to extend, so that the clamping seats on the left and right sides move closer together, driving the bent tubes on the left and right sides to move closer together to achieve the assembly of the automotive bent tube.

[0013] Fourth, the combination of rubber pillars and rubber plates can buffer the outside of the bend, thereby effectively preventing damage to the outside of the bend from rigid contact during clamping. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 4 As shown, the fixture includes a tooling table 101. An assembly base 104 is provided on the upper surface of the tooling table 101. Symmetrically distributed guide rails 105 are provided on the upper surface of the assembly base 104. Sliding seats 106 are slidably mounted on each guide rail 105. A clamping seat 108 is rotatably mounted in the middle of each sliding seat 106 via a rotating shaft 201. Placement grooves 109 are provided on the upper surface of each clamping seat 108. Gears 205 are fixedly fitted onto the outer arc surface of the rotating shaft 201. Symmetrically distributed slide rails 202 are provided inside the sliding seat 106, and sliders are slidably mounted on the outer sides of each slide rail 202. 203, each slider 203 is provided with a rack plate 204 on the side near the gear 205, and the rack plate 204 is meshed with the adjacent gear 205 respectively; the upper surface of the tooling table 101 is provided with symmetrically distributed supports, each support is provided with an electric push rod 107, and the telescopic end of the electric push rod 107 is connected and fixed to the adjacent sliding seat 106 respectively; the front side of the tooling table 101 is provided with a sliding door 103 that is staggered front and back, and the front side of the sliding door 103 is provided with a handle; the lower surface of the tooling table 101 is provided with evenly distributed support feet 102.

[0022] like Figure 2 , 4 As shown, the upper surface of the clamping seat 108 is provided with a mounting bracket 111, and a sliding plate 112 is slidably provided on the lower side of the mounting bracket 111. A pressing block 113 is provided on the lower surface of the sliding plate 112. An electric push rod 114 is provided on the upper end of the mounting bracket 111. The telescopic end of the electric push rod 114 is connected and fixed to the adjacent sliding plate 112 respectively.

[0023] like Figure 2 , 3 As shown, each of the sliding seats 106 has a symmetrically distributed electric push rod 206 on its rear side, and the telescopic ends of the electric push rod 206 are respectively connected and fixed to the adjacent slider 203.

[0024] like Figure 1 , 4 As shown, a control board 301 is provided on the front side of the mounting base 104, and electric push rod 107, electric push rod 214 and electric push rod 3206 are all electrically connected to the control board 301.

[0025] When assembling automotive bends, the automotive bends to be assembled are placed into the placement slots 109 on the left and right sides respectively. Then, the control board 301 controls the operation of the electric push rod 114, so that the telescopic end of the electric push rod 114 drives the slide plate 112 to move vertically downward, thereby driving the clamping block 113 to press down and quickly and stably clamp and fix the automotive bends to be assembled.

[0026] The control panel 301 controls the operation of the electric push rods 206, causing the telescopic ends of the electric push rods 206 near the vertical center of the tooling table 101 to extend and the telescopic ends of the electric push rods 206 away from the vertical center of the tooling table 101 to retract. This causes the rack plate 204 near the vertical center of the tooling table 101 to move forward and the rack plate 204 away from the vertical center of the tooling table 101 to move backward. During the movement of the rack plate 204, the meshing relationship between the rack plate 204 and the gear 205 causes the gear 205 to rotate, which in turn causes the gears 205 on both sides to rotate. The gears 205 then drive the clamping seat 108 to rotate through the rotating shaft 201, so that the bending tubes on the left and right sides are in the same position.

[0027] The control panel 301 regulates the operation of the electric push rod 107, causing the telescopic end of the electric push rod 107 to extend, causing the clamping seats 108 on the left and right sides to move closer together, thereby driving the bent tubes on the left and right sides to move closer together to achieve the assembly of the automotive bent tube.

[0028] According to another embodiment of the present invention, such as Figure 2 , 3 As shown, the interior of the placement groove 109 is provided with evenly distributed rubber pillars 110, and the lower surface of the clamping block 113 is bonded and fixed with a rubber plate. During use, the cooperation of the rubber pillars 110 and the rubber plate can buffer the outside of the bend, thereby effectively preventing damage to the outside of the bend from rigid contact during clamping.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
