Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and more specifically, to a fixture for machining automotive swing arms. Background Technology

[0002] In existing technologies, the clamping components in automotive swing arm machining fixtures typically require position adjustment during machining based on the different sizes or shapes of the parts. Current designs often suffer from inconvenient position adjustment of the clamping components.

[0003] First, adjusting the position of the clamping assembly usually requires manual operation, a tedious and time-consuming process. Operators need to constantly adjust various parts of the fixture or use manual tools to loosen and adjust related fasteners to bring the clamping assembly to the required position. This not only reduces work efficiency but also increases the difficulty of manual operation, especially in high-intensity production environments, where operational errors are prone to occur, thus affecting processing accuracy and production cycle.

[0004] Secondly, in existing technologies, the installation and fixing processes before and after adjustment are relatively complex. Since adjusting the clamping assembly typically involves the disassembly and reassembly of multiple fixing parts, operators need to perform multiple operations, such as disassembling clamps, adjusting component positions, and reinstalling fixing parts. This process not only wastes a significant amount of time and effort but also increases the complexity of the operation. Especially when machining automotive control arms of different sizes, frequent adjustments and fixings require higher operational precision and more stringent process requirements.

[0030] Please see Figures 1-5A machining fixture for automotive swing arms includes a base plate 1, a clamping adjustment mechanism, a position fixing mechanism, and a fixing auxiliary mechanism. The clamping adjustment mechanism includes an adjustment frame 2 and a clamping assembly 3. The adjustment frame 2 is symmetrically installed on the top end of the base plate 1. The clamping assembly 3 is installed on the adjustment frame 2 through the position fixing mechanism. The adjustment frame 2 has adjustment holes 4, and multiple sets of adjustment holes 4 are provided. A clamping tube 101 is fixedly installed on the adjustment frame 2. A moving platform 5 is installed on the bottom end of the clamping assembly 3. One end of the clamping rod 102 can pass through different adjustment holes 4 and engage with the clamping tube 101. The position fixing mechanism includes a rotating plate 6 and a longitudinal pressure ring 7. The rotating plate 6 is rotatably installed on the side wall of the clamping tube 101. The longitudinal pressure ring 7 is longitudinally moved and installed on the outer wall of the clamping tube 101. A rotating ball block 8 is installed on one end of the rotating plate 6. A clamping groove 9 is opened on the side wall of the clamping rod 102. The longitudinal pressure ring 7 presses against the rotating plate 6, causing the rotating ball block 8 to extend into the clamping groove 9, so that the clamping rod 102 is relatively fixed with the clamping tube 101.

[0031] In this embodiment, the clamping adjustment mechanism achieves precise positioning and clamping of the car swing arm through the adjustment frame 2 and the clamping assembly 3. The adjustment frame 2 is symmetrically installed on the top of the base plate 1, providing multiple sets of adjustment holes 4 to accommodate swing arms of different sizes. During operation, the appropriate position of the adjustment hole 4 is selected according to the size of the swing arm, and the locking rod 102 is passed through the adjustment hole 4 and initially connected to the locking tube 101 fixed on the adjustment frame 2. The moving platform 5 at the bottom of the clamping assembly 3 can directly contact the swing arm to form a clamping force. Multiple sets of clamping assemblies 3 can simultaneously apply pressure to the swing arm from different directions to ensure the workpiece... The fixed and stable positioning mechanism achieves a firm connection between the locking rod 102 and the locking tube 101 through the rotating plate 6 and the longitudinal pressure ring 7. After the locking rod 102 passes through the adjustment hole 4 and engages with the locking tube 101, the rotating plate 6 rotates so that the rotating ball block 8 at its end extends into the locking groove 9 on the side wall of the locking rod 102. When the longitudinal pressure ring 7 moves downward, it presses against the rotating plate 6 installed in the rotating groove 20 on the side wall of the locking tube 101, so that the rotating ball block 8 is embedded more deeply into the locking groove 9, thereby firmly locking the locking rod 102 and the locking tube 101, ensuring that the position of the clamping assembly 3 is stable and will not move or loosen.

[0032] The fixed auxiliary mechanism includes an outer rotating sleeve 10 and a double-layer clamping ring 11. The outer rotating sleeve 10 is rotatably mounted on the outer wall of the clamping tube 101. The double-layer clamping ring 11 is fixedly mounted on the outer wall of the clamping tube 101. A spiral plate 201 is mounted on the bottom end of the outer rotating sleeve 10. A spiral groove 12 is provided on the longitudinal pressure ring 7. The spiral plate 201 and the spiral groove 12 are slidably connected. The rotation of the spiral plate 201 causes the longitudinal pressure ring 7 to move longitudinally. A clamping ring 13 is installed on the top end of the outer rotating sleeve 10. A bidirectional spring rod 14 is installed on the clamping ring 13. A positioning hole 15 is provided on the double-layer clamping ring 11. The bidirectional spring rod 14 extends into the positioning hole 15 step by step, so that the outer rotating sleeve 10 rotates stably.

[0033] In this embodiment, the fixing auxiliary mechanism provides precise operation control through the outer rotating sleeve 10 and the double-layer clamping ring 11. When the outer rotating sleeve 10 is rotated, the spiral plate 201 at its bottom engages with the spiral groove 12 on the longitudinal pressure ring 7, converting the rotational motion into the longitudinal movement of the longitudinal pressure ring 7. A bidirectional spring rod 14 is installed on the clamping ring 13 at the top of the outer rotating sleeve 10, which can extend into the positioning hole 15 on the double-layer clamping ring 11 step by step to achieve the graded stable rotation of the outer rotating sleeve 10, prevent accidental loosening, and enable the operator to precisely control the pressure of the longitudinal pressure ring 7 on the rotating plate 6, ensuring the reliability and adjustability of the connection.

[0034] Please see Figures 1-5 As a supplementary embodiment of an automotive swing arm processing fixture for the clamping adjustment mechanism, position fixing mechanism, and fixing auxiliary mechanism: A support frame 16 is installed on the top end of the base plate 1, and the automotive swing arm is fixed on the support frame 16. An auxiliary hole 17 is opened on the support frame 16, and an external bolt plate can pass through the auxiliary hole 17 to initially fix the automotive swing arm. Side plates 18 are installed on both sides of the clamping assembly 3. A clamping tube 101 is fixedly installed on the side plate 18. A connecting plate 19 is installed on the side wall of the clamping tube 101, and the connecting plate 19 is fixedly installed on the side plate 18. A rotating groove 20 is opened on the side wall of the clamping tube 101, and a rotating plate 6 is rotatably installed in the rotating groove 20. Multiple sets of clamping assemblies 3 are provided, and one end of the clamping assembly 3 can press against the top end of the support frame 16.

[0035] More specifically, the car swing arm is placed on the support frame 16 on the top of the base plate 1, and initially fixed by a bolt plate through the auxiliary hole 17 on the support frame 16. The appropriate adjustment hole 4 position is selected according to the shape of the swing arm, and multiple sets of clamping components 3 are installed. The clamping rod 102 passes through the adjustment hole 4 and cooperates with the clamping tube 101. The rotating ball block 8 on the rotating plate 6 extends into the clamping groove 9. The outer rotating sleeve 10 is rotated to make the longitudinal pressure ring 7 move down and press against the rotating plate 6, locking the cooperation between the rotating ball block 8 and the clamping groove 9. The end of the clamping component 3 presses against the swing arm to achieve stable clamping of the workpiece and provide stable support for precise machining. After machining is completed, the outer rotating sleeve 10 is rotated in the opposite direction to release the pressure, which is convenient for disassembly and adjustment. The outer rotating sleeve 10 is rotated in the opposite direction to disengage the clamping rod 102 from the clamping tube 101, and the adjustment hole 4 can be reselected for adjustment.

[0036] In summary, when the overall equipment is in use or operation: when the clamping adjustment mechanism is required to operate, the clamping adjustment mechanism achieves precise positioning and clamping of the car swing arm through the adjustment frame 2 and the clamping assembly 3. The adjustment frame 2 is symmetrically installed on the top of the base plate 1, providing multiple sets of adjustment holes 4 to accommodate swing arms of different sizes. During operation, select the appropriate position of the adjustment hole 4 according to the size of the swing arm, and pass the clamping rod 102 through the adjustment hole 4 to make a preliminary connection with the clamping tube 101 fixed on the adjustment frame 2. The moving platform 5 at the bottom of the clamping assembly 3 can directly contact the swing arm to form a clamping force. Multiple sets of clamping assemblies 3 can simultaneously apply pressure to the swing arm from different directions to ensure that the workpiece is fixed and stable.

[0037] When the position fixing mechanism is in operation, the position fixing mechanism achieves a firm connection between the locking rod 102 and the locking tube 101 through the rotating plate 6 and the longitudinal pressure ring 7. After the locking rod 102 passes through the adjustment hole 4 and engages with the locking tube 101, the rotating plate 6 rotates so that the rotating ball block 8 at its end extends into the locking groove 9 on the side wall of the locking rod 102. When the longitudinal pressure ring 7 moves downward, it presses against the rotating plate 6 installed in the rotating groove 20 on the side wall of the locking tube 101, so that the rotating ball block 8 is embedded more deeply into the locking groove 9, thereby firmly locking the locking rod 102 and the locking tube 101, ensuring that the position of the clamping assembly 3 is stable and will not move or loosen.

[0038] When the auxiliary mechanism is required to operate, it provides precise operation control through the outer rotating sleeve 10 and the double-layer clamping ring 11. When the outer rotating sleeve 10 is rotated, the spiral plate 201 at its bottom engages with the spiral groove 12 on the longitudinal pressure ring 7, converting the rotational motion into the longitudinal movement of the longitudinal pressure ring 7. The clamping ring 13 at the top of the outer rotating sleeve 10 is equipped with a bidirectional spring rod 14, which can extend into the positioning hole 15 on the double-layer clamping ring 11 step by step to achieve the graded stable rotation of the outer rotating sleeve 10, prevent accidental loosening, and enable the operator to precisely control the pressure of the longitudinal pressure ring 7 on the rotating plate 6, ensuring the reliability and adjustability of the connection.

[0039] Place the car swing arm on the support frame 16 on the top of the base plate 1. Use a bolt plate to initially fix it through the auxiliary hole 17 on the support frame 16. Select the appropriate position of the adjustment hole 4 according to the shape of the swing arm. Install multiple sets of clamping components 3. The clamping rod 102 passes through the adjustment hole 4 and cooperates with the clamping tube 101. The rotating ball block 8 on the rotating plate 6 extends into the clamping groove 9. Rotate the outer rotating sleeve 10 to make the longitudinal pressure ring 7 move down and press against the rotating plate 6, locking the cooperation between the rotating ball block 8 and the clamping groove 9. The end of the clamping component 3 presses against the swing arm to achieve stable clamping of the workpiece and provide stable support for precise machining. After machining is completed, rotate the outer rotating sleeve 10 in the opposite direction to release the pressure, which is convenient for disassembly and adjustment. Rotate the outer rotating sleeve 10 in the opposite direction to disengage the clamping rod 102 from the clamping tube 101. The adjustment hole 4 can be reselected for adjustment.
