Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, and more specifically to a brake hub processing fixture. Background Art

[0002] The brake hub is a key part of the automobile, with a wide variety of products. The precision turning process has high requirements for the fixture. At present, more than three cylinders are used to push the fixture to slide and clamp the brake hub on the workbench. However, there will be certain errors when pushing more than three cylinders. For example, if one cylinder retracts slower than the other cylinders, the clamping points of the fixture will be inconsistent, and the brake hub will deviate from the position of the processing tool head, resulting in cutting errors.

[0003] China Patent Authorization Announcement No.: CN219853256U provides a brake hub processing fixture, which uses a hand wheel to rotate a turntable, and a spiral groove is provided on the surface of the turntable. A slider is engaged and connected through the spiral groove, and the slider is restricted by the mounting groove and cannot rotate. Therefore, the rotating spiral groove will move the slider horizontally, and there are four sliders, so there are four clamping seats and clamping plates. The four clamping plates can be brought together at the same time to clamp and fix the brake hub, thereby achieving the purpose of simultaneous clamping.

[0004] However, in this solution, the threaded groove for sliding the slider is opened at the top of the turntable, which makes it easy for small foreign objects to fall into the threaded groove, thereby affecting the normal sliding of the slider and causing inconvenience in use. In addition, this solution clamps the brake hub by rotating the turntable to bring the four clamps together, but the turntable lacks a limiting structure for limiting the position after rotation, which makes it easy for multiple clamps to loosen during processing, and the fixing effect is not ideal. Therefore, a brake hub processing fixture is proposed to address the above problems. Utility Model Content

The design of the movable block can make the movement of multiple clamping blocks more stable and reduce the possibility of sticking. The setting of the spring and rubber pad allows the user to appropriately adjust the clamping force of the brake hub, thereby improving the practicality of the device. The rotating sleeve can be fixed by a limit rod to provide a limiting effect for multiple clamping blocks, thereby ensuring the stability of the clamping and preventing the brake hub from loosening during the processing.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] Example:

[0033] See also Figure 1-2 A brake hub processing fixture includes a base 1 and a plurality of clamping blocks 3. The top of the base 1 is fixedly connected to a fixed table 2. The fixed table 2 is provided with a plurality of movable holes 5, which are arranged in a cross shape. The bottom of the clamping block 3 is fixedly connected to a movable block 4. The movable block 4 is slidably connected to the movable hole 5. A limiting component 6 is arranged on the lower side of the fixed table 2. The limiting component 6 includes a column 601. The column 601 is fixedly connected between the base 1 and the fixed table 2, and the outer end of the column 601 is slidably connected to a sliding sleeve 602. The outer end of the sliding sleeve 602 is rotatably connected to a plurality of connecting rods 603. The end of the connecting rod 603 away from the sliding sleeve 602 is rotatably connected to the movable block 4.

[0034] The brake hub is a key part of the automobile, with a wide variety of products. The precision turning process has high requirements for the fixture. At present, more than three cylinders are used to push the fixture to slide and clamp the brake hub on the workbench. However, there will be certain errors when pushing more than three cylinders. For example, if one cylinder retracts slower than the other cylinders, the clamping points of the fixture will be inconsistent, and the brake hub will deviate from the position of the processing tool head, resulting in cutting errors.

[0035] In this solution, the user can place the brake hub between multiple clamping blocks 3, and the user pulls the rotating sleeve 605 downward to drive the sliding sleeve 602 to move downward through the rotating sleeve 605. The sliding sleeve 602 pulls multiple connecting rods 603 to move, so that the connecting rods 603 rotate at the outer end of the sliding sleeve 602, thereby driving multiple movable blocks 4 to slide in the movable hole 5, so that the multiple clamping blocks 3 move synchronously in the direction of approaching each other, and then push the brake hub to the center position of the upper end of the fixed platform 2 and clamp it. Such a setting can ensure that the multiple movable blocks 4 move synchronously, so that the clamping force applied to each surface of the brake hub is consistent, which can not only improve the stability of the brake hub, but also accurately position the brake hub. Compared with the comparative case, the design of multiple movable blocks 4 can make the movement of multiple clamping blocks 3 more stable and reduce the possibility of jamming.

[0036] See also Figure 2-3 A spring 604 is sleeved on the outer end of the column 601, and both ends of the spring 604 are fixedly connected to the sliding sleeve 602 and the column 601 respectively. Rubber pads are installed on one end of multiple clamping blocks 3 close to each other. The bottom end of the sliding sleeve 602 is rotatably connected to a rotating sleeve 605, and the rotating sleeve 605 is sleeved on the outer end of the column 601.

[0037] In this solution, the spring 604 is in a contracted state in the initial state. When the user pulls down the sliding sleeve 602 to bring the multiple clamping blocks 3 closer to each other, the spring 604 is continuously stretched. The setting of the rubber pads at the inner ends of the multiple clamping blocks 3 provides a certain buffer space between the clamping blocks 3 and the brake hub, which protects the outer surface of the brake hub. At the same time, when the user pulls down the rotating sleeve 605, the rubber pad will also be squeezed between the clamping block 3 and the brake hub, so that the user can control the clamping degree of the multiple clamping blocks 3 on the brake hub. For some brake hubs with special protective components on the outer surface, the clamping force can be appropriately reduced.

[0038] See also Figure 4 The outer ends of the columns 601 are respectively provided with connecting grooves 607 and a plurality of limiting grooves 608 , the plurality of limiting grooves 608 are arranged at equal intervals, and the limiting grooves 608 are connected to the connecting grooves 607 , the inner end of the rotating sleeve 605 is fixedly connected to the limiting rod 606 , and the connecting grooves 607 and the limiting grooves 608 are matched with the limiting rod 606 .

[0039] The user drives the sliding sleeve 602 to move downward by pulling the rotating sleeve 605. During the downward movement of the rotating sleeve 605, the limiting rod 606 moves in the connecting groove 607. When the user confirms that the brake hub has been clamped and adjusts the clamping force, the rotating sleeve 605 can be rotated to make the limiting rod 606 slide into the corresponding limiting groove 608, thereby fixing the current position of the rotating sleeve 605 and achieving stable clamping of the brake hub.

[0040] Working principle:

[0041] When in use, the user can place the brake hub in the position between the multiple clamping blocks 3, and then pull the rotating sleeve 605 downwards, and the sliding sleeve 602 is driven to move downwards by the rotating sleeve 605, and the sliding sleeve 602 pulls the multiple connecting rods 603 to move, so that the connecting rods 603 rotate at the outer end of the sliding sleeve 602, thereby driving the multiple movable blocks 4 to slide in the movable holes 5, so that the multiple clamping blocks 3 move synchronously in the direction of approaching each other, and then push the brake hub to the center position of the upper end of the fixed platform 2 and clamp it. When the user pulls the rotating sleeve 605 downwards, the spring 604 is continuously stretched, and the limiting rod 606 in the rotating sleeve 605 moves in the connecting groove 607. When the user confirms that the brake hub has been clamped and adjusts the clamping force, the rotating sleeve 605 can be rotated to make the limiting rod 606 slide into the corresponding limiting groove 608, thereby fixing the current position of the rotating sleeve 605 and achieving stable clamping of the brake hub.

[0042] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
