[0024] As shown in Figure 1 and Figure 2 An automobile brake caliper with a stabilizing support structure and a quick positioning structure, characterized in that: comprising a caliper blank 1 and a positioning frock 2;

[0025] As shown in Figure 3 The caliper blank 1 is provided with a main positioning point 11, a positioning groove 12 and a guide surface 13;The positioning frock 2 comprises a bottom plate 21 and a positioning clamp, and the positioning clamp is fixedly connected to the bottom plate 21;Wherein, the main positioning point 11, the positioning groove 12 and the guide surface 13 are one-time formed with the blank. It can be pressure casting.

[0026] As shown in Figure 4As shown, the bottom plate 21 is provided with a center positioning column 22, a first positioning column 23 and a second positioning column 24, and the caliper blank 1 is installed on the positioning tool 2, and the main positioning point 11, the positioning groove 12 and the guide surface 13 correspond to the center positioning column 22, the second positioning column 24 and the first positioning column 23 respectively.

[0027] The main function of the main positioning point 11 is to control the axial movement of the blank, ensuring that it does not move unnecessarily along the axis during assembly. It provides a preliminary alignment reference point, allowing the blank to quickly and accurately interface with the corresponding parts on the tool. The main positioning point can be a precisely machined hole or recess, which cooperates with the center positioning column 22 on the tool. When the caliper blank 1 is placed on the positioning tool 2, the center positioning column 22 can be a tapered positioning pin that automatically inserts into the main positioning hole, achieving precise axial positioning. This design not only improves positioning accuracy, but also allows the blank to easily slide into place, reducing assembly difficulty.

[0028] The positioning groove 12 is used to limit the radial movement of the blank, ensuring that its lateral position is fixed and preventing rotation or deviation from the center. It provides a clear path for the blank, helping it slide into the tool in the correct direction and simplifying the assembly process. The positioning groove 12 can be a groove machined along the edge of the blank, designed in shape and size to match the second positioning column 24 on the tool. When the caliper blank 1 is placed on the tool, the positioning groove 12 comes into contact with the second positioning column 24 and slides, guiding the caliper blank 1 to the final position. This not only ensures the correct positioning of the blank, but also reduces the need for manual adjustment.

[0029] The guide surface 13 is used to fine-tune the height of the blank, ensuring that its vertical position is correct and avoiding excessive height or low height. Through the guide surface 13, the front and rear pitch angle of the caliper blank 1 can be controlled, keeping it in a horizontal state and preventing tilting. The guide surface 13 is designed as a slope or a specially shaped surface, which cooperates with the first positioning column 23 on the tool. When the caliper blank 1 is installed, the guide surface 13 comes into contact with the first positioning column 23, and as the blank gradually presses down, the guide surface 13 automatically adjusts the height and flatness of the blank until it reaches the optimal assembly state. In addition, the guide surface can also help distribute pressure and reduce local stress concentration, protecting the blank from damage.

[0030] The positioning fixture includes a cylinder hole positioning assembly 25 and a hook claw positioning assembly 27. The cylinder hole positioning assembly 25 includes a cylinder hole pressing plate pad 251 and a cylinder hole positioning screw 253. The cylinder hole pressing plate pad 251 is arranged on the bottom plate 21, and the cylinder hole pressing plate pad 251 and a cylinder hole pressing plate 252 are sleeved on the cylinder hole positioning screw 253. One end of the cylinder hole pressing plate 252 is fixedly connected to the cylinder hole pressing plate pad 251, and the cylinder hole positioning screw 253 is threadedly connected with an upper adjusting nut 255 and a lower adjusting nut 254 respectively. The cylinder hole pressing plate 252 is in sliding connection with the cylinder hole positioning screw 253.

[0031] By adjusting the upper adjusting nut 255 and the lower adjusting nut 254, the degree of downward pressure of the cylinder hole pressing plate 252 can be controlled, ensuring accurate positioning of the brake caliper blank 1 during installation and reducing the impact of assembly errors. The cylinder hole pressing plate pad 251 provides a stable support point, allowing the cylinder hole pressing plate 252 to stably exert pressure thereon, thereby ensuring the reliability of cylinder hole positioning. This is crucial for the performance of the braking system, as any looseness or instability can lead to a decrease in braking effectiveness. Due to the threaded connection between the cylinder hole positioning screw 253 and the upper and lower adjusting nuts 255, 254, different models or sizes of brake calipers can be adjusted flexibly, improving the versatility and adaptability of the tooling. If it is necessary to replace or adjust the position of the cylinder hole pressing plate 252, the corresponding adjusting nut can be loosened, which simplifies the maintenance process and reduces maintenance costs.

[0032] The hook claw positioning assembly 27 includes a hook claw positioning support block 271 and a clamping screw 272. The hook claw positioning support block 271 is fixedly connected to the bottom plate 21, and the clamping screw 272 is threadedly connected to the hook claw positioning support block 271. A fixing nut is threadedly connected to the clamping screw 272.

[0033] The hook claw positioning support block 271 provides a stable support platform for the hook claw positioning assembly 27. By using the clamping screw 272 and the fixing nut in combination with the cylinder hole positioning assembly 25, the caliper blank 1 can be securely fixed on the positioning tool 2, preventing loosening or displacement and ensuring the stability of subsequent processing.

[0034] The threaded connection between the clamping screw 272 and the fixing nut allows for fine adjustment of the positioning position of the hook claw positioning assembly 27. This enables quick adaptation and precise positioning even when switching between different models or sizes of brake calipers.

[0035] The clamping screw 272 and the fixing nut are simple and intuitive to operate. Assembly personnel can complete installation or disassembly by manually tightening or loosening, without the need for complex tools or equipment.

[0036] The number of the claw positioning assemblies 27 is 2. Two claw positioning assemblies 27 can more evenly share the pressure and stress from the caliper blank 1, preventing deformation or damage caused by excessive force on a single point.

[0037] As shown in Figure 5 The positioning fixture further includes a claw pressing plate assembly 26, which includes a pressing plate support column 261, a pressing plate 262, and an adjusting screw 264. The pressing plate 262 is arranged on the pressing plate support column 261, and the adjusting screw 264 is fixed at one end to the bottom plate 21 and connected at the other end to the pressing plate 262. A pressing plate fixing nut 263 is threadedly connected to the adjusting screw 264. The pressing plate support column 261 can be a screw that cooperates with a matching nut to fix the pressing plate 262. The advantage of the pressing plate support column 261 being a screw is that the overall height of the pressing plate 262 can be adjusted.

[0038] The main function of the claw pressing plate assembly 26 is to firmly fix the brake caliper blank 1 on the positioning tool 2. By applying pressure through the pressing plate 262, it ensures that the blank does not move or shake during the entire machining and assembly process. The pressing plate 262 has two extensions that correspond to the claw gaps of the caliper blank 1.

[0039] Through the cooperation of the adjusting screw 264 and the pressing plate fixing nut 263, the pressing plate 262 can be firmly pressed on the blank, ensuring that it does not shift during the entire assembly process. This enhances the stability of the blank on the tool, which is particularly important for components that require high-precision positioning.

[0040] Different assembly tasks may require different pressure or clamping force. By adjusting the position of the pressing plate 262 on the adjusting screw 264, the pressure applied by the pressing plate 262 can be flexibly adjusted to meet various assembly requirements.

[0041] The design of the claw pressing plate assembly 26 allows the blank to be quickly and accurately placed in position and fixed through simple tightening operations, greatly simplifying the assembly process and reducing the time for manual intervention.

[0042] The caliper blank 1 is made of ductile iron 500-7. Ductile iron 500-7 is a high-strength cast iron material with high tensile strength, yield strength, and hardness, capable of withstanding large stresses without deformation or fracture. This is particularly important for components in the braking system that require high reliability. Compared to ordinary cast iron, ductile iron 500-7 has better toughness and is less likely to break under impact load, improving safety and durability.

[0043] Place the caliper blank 1 on the positioning tool 2 so that the main positioning point 11 coincides with the conical center positioning column 22. At this time, the center positioning column 22 will be inserted into the main positioning point 11, achieving preliminary axial positioning.

[0044] Radial positioning: Continue to slide the caliper blank 1 along the guide surface 13 until the positioning slot 12 comes into contact with the second positioning post 24, ensuring that the caliper blank 1 is fixed in lateral position, preventing rotation or deviation from the center.

[0045] Height adjustment: Through the cooperation of the guide surface 13 and the first positioning post 23, the height of the blank is fine-tuned to control its front and back pitch angle, keeping it in a horizontal state to avoid tilting.

[0046] One end of the caliper blank 1 is a cylinder hole, and the other end is a hook claw.

[0047] Cylinder hole positioning: Use the cylinder hole positioning assembly 25 to control the degree of downward pressure of the cylinder hole pressing plate 252 by adjusting the upper adjusting nut 255 and the lower adjusting nut 254, ensuring accurate positioning of the brake caliper blank 1.

[0048] Hook claw positioning: Use two hook claw positioning assemblies 27 to firmly fix the caliper blank 1 on the positioning tool 2 by means of clamping screws 272 and fixing nuts, preventing loosening or displacement.

[0049] Hook claw pressing plate fixation: By means of the hook claw pressing plate assembly 26, the pressing plate 262 is set on the pressing plate support column 261, further reinforcing the caliper blank 1 to ensure that it does not move or shake during the entire processing process.

[0050] After the above fixation is completed, the necessary processing procedures such as drilling, milling, etc. can be started. Since the blank has been accurately positioned, the processing precision is guaranteed. After processing is completed, subsequent assembly procedures such as installation of piston, brake pad, etc. can be carried out. All these steps can be carried out in the stable state of the blank, reducing the error caused by the movement of the blank.

[0051] When all processing and assembly procedures are completed, loosen all the fixing nuts and screws, and carefully remove the caliper blank 1 from the positioning tool 2. Finally, the finished product is strictly quality inspected to ensure that every detail meets the design requirements and technical standards.

[0052] The caliper blank itself has positioning structure, eliminating the need for secondary processing, simplifying the production process and shortening the production cycle.

[0053] Improve production efficiency: The preset positioning holes and slots make the assembly process more efficient, reducing the time for manual adjustment and improving production efficiency.

[0054] Improve product quality: The accurate design of the positioning structure ensures the accurate relative position between the parts, improving the overall quality and reliability of the product.

[0055] Cost reduction: reduces secondary processing procedures, reduces production cost.

[0056] The three positioning points provide a stable triangular support structure, making the blank more stable during assembly and less likely to shift or tilt. This stability is crucial for high-precision machining and assembly. Three-point positioning can more evenly distribute pressure and stress from the blank, preventing localized excessive force that can cause deformation or damage, thereby protecting the quality of the blank.

[0057] The utility model is described above by way of example, but the utility model is not limited to the above specific embodiments, any modification or modification based on the utility model belongs to the range of the utility model claimed.
