Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a combined fixing fixture for automotive chassis components. Background Technology
[0002] The car chassis is an important component of a car, mainly composed of a clutch, transmission, universal joint, final drive, differential, and half shafts. The clutch allows the engine power to smoothly engage or disengage from the transmission. The transmission changes the gear ratio to achieve functions such as speed change and output torque variation. The universal joint can transmit power between shafts with changing axes. The final drive reduces speed and increases torque. The differential adjusts the speed difference between the left and right tires. The half shafts connect the differential to the drive wheels and transmit torque.
[0003] When processing automotive chassis components, modular fixing fixtures for automotive chassis components are used to quickly and accurately position and reliably clamp various chassis components. This provides tooling equipment to meet different production needs. The quick changeover and efficient clamping and positioning methods greatly reduce workpiece clamping time and production preparation time, improve production cycle time, and enable the production line to operate more efficiently.
[0004] In existing technologies, the position of a component in a fixture is determined by contacting a positioning element with a positioning reference surface on the chassis component. During machining and assembly, the fixture is connected to the machine tool table and other equipment via a base platform to ensure that the component is in the correct position for machining and assembly operations. However, the adjustment range of specifications is small and the function is limited, making it difficult to meet the needs of special-specification components and various machining operations. To address this, a fixture structure with a large stroke and multiple degrees of freedom adjustment is needed. For example, a telescopic and rotatable positioning and clamping device can be used to achieve precise position adjustment through motor and hydraulic drive to adapt to chassis components of different sizes and shapes. However, the overall rigidity of the fixture is insufficient, especially when fixing large and heavy chassis components, which is prone to deformation and cannot guarantee the positional accuracy of the chassis during machining. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a combined fixing fixture for automobile chassis components, which aims to improve the problem in the prior art that deformation is easily caused when fixing large and heavy chassis components, and the positional accuracy of the frame cannot be guaranteed during the processing.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a combined fixing fixture for automobile chassis components, including a base, a worktable fixedly connected to the center of the top wall of the base, multiple bases fixedly connected at equal intervals to the top of the worktable, a processing table fixedly connected to the top of the base, a fixing seat installed on the rear side of the processing table, a hydraulic rod installed on the inner side of the fixing seat, a fixing block fixedly connected to the rear top of the processing table, an installation block fixedly connected to the front end of the hydraulic rod, a rotating shaft 1 rotatably connected to the left and right sides of the outer wall of the installation block, a clamping block rotatably connected to the outer wall of the rotating shaft 1, a rubber block installed on the inner side of the clamping block, a rotating shaft 3 rotatably connected to the inner side of the clamping block, a connecting block installed on the front side of the fixing block, a rotating shaft 2 rotatably connected to the left and right sides of the connecting block, a connecting rod rotatably connected to the outer wall of the rotating shaft 2, the end of the connecting rod rotatably connected to the outer wall of the rotating shaft 3, and a shock-absorbing mechanism installed at each of the four corners of the bottom of the processing table, the shock-absorbing mechanism being used to reduce the vibration impact generated by the equipment.
[0007] As a further description of the above technical solution:
[0008] The shock absorption mechanism includes a mounting plate one, which is installed at the four corners of the bottom of the processing table. Multiple damping rods are equidistantly installed on the middle of the bottom wall of the mounting plate one. Springs are installed on the outer wall of the damping rods. A mounting plate two is installed at the end of the damping rods. A connecting plate one is equidistantly installed on the outer bottom of the mounting plate one. A connecting plate two is rotatably connected to the end of the connecting plate one. A connecting plate three is rotatably connected to the end of the connecting plate two. The connecting plate three is connected to the mounting plate two.
[0009] As a further description of the above technical solution:
[0010] An electrical wire is installed on the right side of the outer wall of the workbench, and a controller is installed at the end of the electrical wire.
[0011] As a further description of the above technical solution:
[0012] A hinge is installed on the right side of the outer wall of the workbench, and a door panel is installed on the upper middle part of the front side of the outer wall of the hinge.
[0013] As a further description of the above technical solution:
[0014] Two handles are installed on the left and right ends of the front side of the outer wall of the door panel.
[0015] As a further description of the above technical solution:
[0016] Anti-slip sleeves are fixedly connected to the rear side of each of the handles.
[0017] As a further description of the above technical solution:
[0018] The base is fixedly connected to four corners at the top.
[0019] As a further description of the above technical solution:
[0020] A hydraulic chamber is fixedly connected to the top of the fixed column.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the hydraulic rod extends and retracts to move the mounting block, and the movement of the mounting block causes the clamping block to rotate on the outer wall of the rotating shaft. When the hydraulic rod retracts, it pulls the mounting block backward, and the mounting block drives the rotating shaft to move backward, causing the clamping block to open. When the hydraulic rod extends, it pushes the mounting block to clamp the clamping block. The back-and-forth extension and retraction of the hydraulic rod enables the clamping block to perform clamping and opening actions. In this way, the clamping block can clamp the mold and hold and fix the mold. In this way, the mold can remain stable during processing and will not be displaced, ensuring the positional accuracy of the frame during processing.
[0023] 2. In this utility model, the vibration of the processing table transmits the force to the mounting plate one. The mounting plate one shakes and compresses the damping rod, which in turn compresses the spring. When the spring is subjected to vibration, it undergoes elastic deformation, absorbing and buffering the vibration energy. This allows the damping rod to adapt to the weight of the processing table and the vibration frequency during vibration, further improving the vibration resistance of the processing table. It can effectively isolate the vibration generated during chassis processing and avoid loosening, wear, or even damage of parts due to long-term vibration. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a combined fixing fixture for automobile chassis components, including a base 1, a worktable 3 fixedly connected to the center of the top wall of the base 1, a plurality of bases 13 fixedly connected at equal intervals to the top of the worktable 3, a processing table 12 fixedly connected to the top of the bases 13, a fixing seat 14 installed on the rear side of the processing table 12, a hydraulic rod 15 installed on the inner side of the fixing seat 14, a fixing block 22 fixedly connected to the rear top of the processing table 12, and an mounting block 16 fixedly connected to the front end of the hydraulic rod 15. Rotating shaft 17 is rotatably connected to both the left and right sides of the outer wall of 6. A clamping block 24 is rotatably connected to the outer wall of rotating shaft 17. A rubber block 20 is installed on the inner side of clamping block 24. Rotating shaft 23 is rotatably connected to the inner side of clamping block 24. A connecting block 21 is installed on the front side of fixing block 22. Rotating shaft 18 is rotatably connected to both the left and right sides of connecting block 21. A connecting rod 19 is rotatably connected to the outer wall of rotating shaft 18. The end of connecting rod 19 is rotatably connected to the outer wall of rotating shaft 23. Hydraulic rod 15 drives the movement of mounting block 16 through its telescopic motion. When the hydraulic rod 15 extends, it pushes the mounting block 16 along a specific path, thereby causing the clamping block 24 to rotate on the outer wall of the rotating shaft 17. When the hydraulic rod 15 retracts, it pulls the mounting block 16 backward, causing the rotating shaft 17 to retract, thus opening the clamping block 24. Conversely, when the hydraulic rod 15 extends again, it pushes the mounting block 16 forward, and the clamping block 24 clamps accordingly. The reciprocating extension and retraction motion of the hydraulic rod 15 enables the clamping block 24 to perform clamping and opening actions. Through this mechanism, the clamping block 24 can accurately clamp... The mold is taken out and effectively clamped and fixed, so the mold can remain stable during the processing operation, avoiding unnecessary displacement and ensuring the positional accuracy of the frame during the processing. The four corners of the bottom of the processing table 12 are equipped with shock absorption mechanisms 2 to reduce the impact of vibration generated by the equipment. The outer right side of the workbench 3 is equipped with a wire 9, and the end of the wire 9 is equipped with a controller 8. The outer right side of the workbench 3 is equipped with a hinge 4, and the upper front part of the outer wall of the hinge 4 is equipped with a door panel 5.
[0033] Specifically, the hydraulic rod 15 extends and retracts, causing the mounting block 16 to move. The movement of the mounting block 16 causes the clamping block 24 to rotate on the outer wall of the rotating shaft 17. When the hydraulic rod 15 retracts, it pulls the mounting block 16 backward. The mounting block 16 then causes the rotating shaft 17 to move backward, causing the clamping block 24 to open. When the hydraulic rod 15 extends, it pushes the mounting block 16 to clamp the clamping block 24. The back-and-forth extension and retraction of the hydraulic rod 15 enables the clamping block 24 to perform clamping and opening actions. In this way, the clamping block 24 can clamp the mold and hold and fix the mold. In this way, the mold can remain stable during processing and will not be displaced, ensuring the positional accuracy of the frame during processing.
[0034] Reference Figure 2 , Figure 3 and Figure 4The vibration damping mechanism 2 includes a mounting plate 201, which is installed at the four corners of the bottom of the processing table 12. Multiple damping rods 205 are equidistantly installed on the middle of the bottom wall of the mounting plate 201. Springs 204 are installed on the outer wall of each damping rod 205. A mounting plate 206 is installed at the end of each damping rod 205. A connecting plate 202 is equidistantly installed on the outer bottom of the mounting plate 201. A connecting plate 203 is rotatably connected to the end of the connecting plate 202. A connecting plate 207 is rotatably connected to the end of the connecting plate 203. The connecting plate 207 is connected to the mounting plate 206. During operation of the processing table 12, the vibrations generated are transmitted to the mounting plate 201 through the structure, causing the vibrations to... When plate 201 shakes, this shaking action acts on damping rod 205, causing it to be compressed. After being compressed, damping rod 205 further compresses spring 204. Spring 204 undergoes elastic deformation under the influence of vibration. This deformation can absorb and buffer vibration energy. Through this mechanism, damping rod 205 can adapt to the weight and vibration frequency of processing table 12, thereby improving the vibration resistance of processing table 12. This design effectively isolates the vibration generated during chassis processing, preventing loosening, wear, or even damage of parts due to long-term vibration, ensuring the stable operation of processing equipment and processing quality. Two handles 6 are installed on the left and right ends of the front side of the outer wall of door panel 5, and anti-slip sleeves 7 are fixedly connected to the rear side of multiple handles 6.
[0035] Specifically, the vibration of the processing table 12 transmits the force to the mounting plate 201. The mounting plate 201 shakes and compresses the damping rod 205. The damping rod 205 then compresses the spring 204. When the spring 204 is subjected to vibration, it undergoes elastic deformation, absorbing and buffering the vibration energy. This allows the damping rod 205 to adapt to the weight of the processing table 12 and the vibration frequency during vibration, further improving the vibration resistance of the processing table 12. It can effectively isolate the vibration generated during chassis processing and prevent parts from loosening, wearing, or even being damaged due to long-term vibration.
[0036] Reference Figure 1 , Figure 2 and Figure 3 A fixed column 10 is fixedly connected to each of the four corners at the top of the base 1, and a hydraulic chamber 11 is fixedly connected to the top of the fixed column 10.
[0037] Specifically, the fixed column 10 is used to support the hydraulic chamber 11. The hydraulic chamber 11 is generally made of metal material and has a certain strength and sealing performance. The hydraulic pump in the hydraulic chamber 11 draws hydraulic oil from the oil tank, pressurizes it and delivers it to various parts of the hydraulic system to accommodate the various components of the hydraulic system and prevent hydraulic oil leakage.
[0038] Working principle: The hydraulic rod 15 drives the mounting block 16 to move through its telescopic movement. When the hydraulic rod 15 extends, it pushes the mounting block 16 to move along a specific path. The movement of the mounting block 16 causes the clamping block 24 to rotate on the outer wall of the rotating shaft 17. As the hydraulic rod 15 retracts, it pulls the mounting block 16 backward, causing the rotating shaft 17 to move backward, resulting in the clamping block 24 opening. Conversely, when the hydraulic rod 15 extends again, it pushes the mounting block 16 forward, causing the clamping block 24 to clamp. This reciprocating telescopic movement of the hydraulic rod 15 enables the clamping block 24 to perform clamping and opening actions. In this way, the clamping block 24 can accurately clamp the mold and effectively hold and fix it. As a result, the mold can remain stable during processing and will not undergo unnecessary displacement, thus ensuring the positional accuracy of the frame during processing.
[0039] The vibration generated by the machining table 12 during operation is transmitted to the mounting plate 201 through the structure. The mounting plate 201 will shake under the action of vibration. This shaking will compress the damping rod 205. After being compressed, the damping rod 205 will further compress the spring 204. The spring 204 will undergo elastic deformation under the action of vibration. This deformation can absorb and buffer the vibration energy. In this way, the damping rod 205 can adapt to the weight of the machining table 12 and the vibration frequency during vibration, thereby further improving the vibration resistance of the machining table 12. This design can effectively isolate the vibration generated during chassis machining, avoid component loosening, wear or even damage caused by long-term vibration, and ensure the stability of the machining equipment and the machining quality.
