Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, and in particular to a three-way positioning tooling for automotive steering systems. Background Technology

[0002] Steering gear positioning fixtures are used to fix steering gears to ensure the smooth conduct of steering gear testing. However, existing steering gear fixtures cannot position steering gears of different models, and they also suffer from high costs and poor positioning effects.

[0003] To address the aforementioned technical issues, a patent document with publication number (CN217728533U) discloses a three-way positioning fixture for automotive steering systems. This fixture includes a base plate, guide slides, guide sliders, positioning sliders, and positioning posts. The upper surface of the base plate has at least two guide slides, all horizontally positioned along the width of the base plate. Guide grooves are formed along the length of the base plate. Guide sliders, each with a corresponding guide groove, are positioned on the guide slides and have corresponding guide sliders. Each guide slide has at least one positioning slider on its upper surface, which can slide along the width of the base plate. The top wall of each positioning slider has a receiving groove, within which a positioning post, adapted to its structure, is nested. The top wall of each positioning post has a positioning screw hole, and a positioning bolt is threaded into each positioning screw hole. This invention is applicable to positioning automotive steering systems with different structures.

[0004] However, in the aforementioned existing technologies, adjusting the positioning fixture requires turning multiple bolts separately, which is very time-consuming and labor-intensive, resulting in low efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a three-way positioning fixture for automotive steering gear, which aims to solve the technical problem in the prior art that when adjusting the positioning fixture, it is necessary to tighten multiple bolts separately, which is very time-consuming and labor-intensive, resulting in low efficiency.

[0006] To achieve the above objectives, this utility model employs a three-way positioning fixture for an automotive steering gear, comprising a base plate and a positioning mechanism. The positioning mechanism includes two mounting plates, a bidirectional threaded rod, two movable plates, two sets of fixing components, and a movable component. Each set of fixing components includes a T-block, a sliding plate, two round rods, two fixing blocks, and a mounting piece. The two mounting plates are fixedly connected to the upper surface of the base plate. The bidirectional threaded rods pass through the two movable plates and are threadedly engaged with them. Both ends of the bidirectional threaded rods are rotatably connected to the two mounting plates. The movable component is disposed on the upper surface of the base plate. The two sets of fixing components are disposed on the upper ends of the two movable plates. One end of the T-block is fixedly connected to the corresponding movable plate, and the other end of the T-block is slidably connected to the sliding plate. Both fixing blocks are disposed on the upper surface of the sliding plate. One end of each of the two round rods is fixedly connected to the movable component, and the other ends of the two round rods pass through the two fixing blocks. The mounting piece is disposed on the upper surface of the sliding plate.

[0007] The movable component includes two upright plates, a lead screw, a support block, and a support plate. The two upright plates are fixedly connected to the upper surface of the base plate. The lead screw passes through the support block and is threadedly engaged with the support block. The two ends of the lead screw are rotatably connected to the two upright plates respectively. The support plate is fixedly connected to the upper end of the support block.

[0008] The mounting components include a lifting plate, a pin, a nut, and a lifting element. The lifting element is disposed on the upper surface of the slide plate, the lifting plate is disposed above the lifting element, the pin is fixedly connected to the upper surface of the lifting plate, and the nut is threadedly connected to the pin.

[0009] The lifting component includes a base and a first threaded rod. The base is fixedly connected to the slide plate and is located on the upper surface of the slide plate. One end of the first threaded rod is fixedly connected to the lifting plate, and the other end of the first threaded rod is inserted into the interior of the base and threadedly engaged with the base.

[0010] The three-way positioning fixture for the automotive steering gear also includes two sliders and a guide rod. The two sliders are fixedly connected to the two movable plates respectively. The guide rod passes through the two sliders and is slidably connected to the two sliders respectively. The two ends of the guide rod are fixedly connected to the two mounting plates respectively.

[0011] This utility model discloses a three-way positioning fixture for an automotive steering gear. A bidirectional threaded rod passes through two movable plates and is threadedly engaged with each plate. The other end of a T-block is slidably connected to a sliding plate. One end of each of two round rods is fixedly connected to a movable assembly, and the other ends of each rod pass through two fixed blocks. In practical use, starting a first motor causes the bidirectional threaded rod to rotate, resulting in relative movement of the two movable plates. Each movable plate then moves its corresponding T-block, which in turn moves the sliding plate left and right. The sliding plate then moves the two fixed blocks in their respective positions. The circular rod slides on the slide plate, while the sliding plate drives the fixing component to move left and right, thereby adjusting the distance between the two sets of fixing components. Then, the moving component drives multiple circular rods to move back and forth, and the multiple circular rods drive the corresponding fixing blocks to move back and forth. The fixing blocks drive the sliding plate to slide on the T-block, and the sliding plate drives the fixing component to move back and forth, thereby adjusting the front and rear position of the fixing component. Finally, the car steering gear is installed on the two sets of fixing components. This method can effectively solve the problem in the prior art that when adjusting the positioning fixture, it is necessary to tighten multiple bolts separately, which is very time-consuming and labor-intensive, resulting in low efficiency.

[0021] In this specific embodiment, both mounting plates 102 are fixedly connected to the upper surface of the base plate 101. The bidirectional threaded rod 103 passes through both movable plates 104 and is threadedly engaged with each of the two movable plates 104. Both ends of the bidirectional threaded rod 103 are rotatably connected to the two mounting plates 102. The movable assembly is disposed on the upper surface of the base plate 101. Two sets of fixing assemblies are respectively disposed on the upper ends of the two movable plates 104. One end of the T-shaped block 105 is fixedly connected to the corresponding movable plate 104, and the other end of the T-shaped block 105 is slidably connected to the slide plate 106.

The mounting component is disposed on the upper surface of the slide plate 106. In actual use, the device is activated. The first motor 120 drives the bidirectional threaded rod 103 to rotate, causing the two movable plates 104 to move relative to each other. The two movable plates 104 respectively drive the corresponding T-shaped blocks 105 to move. The T-shaped blocks 105 drive the sliding plate 106 to move left and right. The sliding plate 106 drives the two fixed blocks 108 to slide on the corresponding round rods 107. At the same time, the sliding plate 106 drives the fixed components to move left and right, thereby adjusting the distance between the two sets of fixed components. Then, the movable components drive multiple round rods 107 to move back and forth. The multiple round rods 107 drive the corresponding fixed blocks 108 to move back and forth. The fixed blocks 108 drive the sliding plate 106 to slide on the T-shaped blocks 105. The sliding plate 106 drives the fixed components to move back and forth, thereby adjusting the front and rear position of the fixed components. Finally, the car steering gear is installed on the two sets of fixed components.

In actual use, the lifting component drives the lifting plate 113 to move up and down, the lifting plate 113 drives the pin 114 to move up and down, and then the pin 114 is inserted into the mounting hole on the car steering gear, and then the nut 115 is tightened to fix the car steering gear to the pin 114.

[0024] Meanwhile, the base 116 is fixedly connected to the slide plate 106 and is located on the upper surface of the slide plate 106. One end of the first threaded rod 117 is fixedly connected to the lifting plate 113, and the other end of the first threaded rod 117 is inserted into the interior of the base 116 and threadedly engaged with the base 116. In actual use, rotating the lifting plate 113 causes the first threaded rod 117 to rotate, thereby moving the first threaded rod 117 up or down.

[0025] In addition, the two sliders 118 are fixedly connected to the two movable plates 104 respectively, and the guide rods 119 pass through the two sliders 118 respectively and are slidably connected to the two sliders 118 respectively. The two ends of the guide rods 119 are fixedly connected to the two mounting plates 102 respectively. In actual use, the movement of the two movable plates 104 drives the two sliders 118 to rotate on the corresponding guide rods 119, thereby guiding the two movable plates 104.

[0026] In the specific use of the three-way positioning fixture for an automotive steering gear according to this embodiment, the first motor 120 is started. The output end of the first motor 120 drives the bidirectional threaded rod 103 to rotate, causing the two moving plates 104 to move relative to each other.

The support block 111 drives the support plate 112 to move back and forth. The support plate 112 drives multiple rods to move back and forth. The circular rod 107 moves back and forth, and the multiple circular rods 107 drive the corresponding fixed block 108 to move back and forth. The fixed block 108 drives the sliding plate 106 to slide on the T-shaped block 105. The sliding plate 106 drives the base 116 to move back and forth, thereby adjusting the front and back position of the pin 114. By rotating the lifting plate 113, the lifting plate 113 drives the first threaded rod 117 to rotate, causing the first threaded rod 117 to move up and down, thereby adjusting the height of the pin 114. Finally, the two pins 114 are respectively passed through the mounting holes on the car steering gear, and the two nuts 115 are tightened respectively, thereby completing the positioning of the car steering gear.
