Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to a positioning device for processing aluminum parts for motorcycle sleeves. Background Technology

[0002] Aluminum sleeve parts are an indispensable and important component of motorcycles, mainly used in suspension systems, shock absorbers, and other critical parts. They not only need sufficient strength and durability to withstand impacts under various road conditions, but their machining precision directly affects engine performance and lifespan. Traditional methods for machining and positioning motorcycle aluminum sleeve parts often employ three-jaw chucks or specialized fixtures.

[0003] When using a three-jaw chuck for machining and positioning, employees usually need to clamp the parts themselves. This is highly susceptible to human error, making it difficult to ensure the coaxiality and perpendicularity of the workpiece during clamping. Auxiliary tools are usually required for verification, which is time-consuming and results in low positioning accuracy. Traditional special fixtures are typically complex in structure, requiring employees to consult work manuals and rely on experience for clamping. This involves tightening many clamping screws, making the operation cumbersome and inefficient. Therefore, this application proposes a positioning device for machining aluminum parts for motorcycle sleeves. Summary of the Invention

[0004] The purpose of this utility model is to address the problems in the background technology where three-jaw chucks are difficult to guarantee the coaxiality and perpendicularity of workpieces during clamping, usually requiring auxiliary tools for verification, which is time-consuming, has low positioning accuracy, and traditional special fixtures are cumbersome to operate and have low efficiency. The present invention proposes a positioning device for machining aluminum parts for motorcycle sleeves.

[0005] The technical solution of this utility model: A positioning device for processing aluminum sleeve parts for motorcycles, including a base, and further comprising:

[0006] A V-shaped positioning block is fixedly installed on the base. A first support block and a second support block are fixedly installed on one side of the V-shaped positioning block on the base. A first top pin is connected to the first support block. A top cap is provided on the second support block. A positioning cylinder is installed on the side of the base close to the second support block. A second top pin is provided on one side of the positioning cylinder.

[0007] A pneumatic swing mechanism, wherein two pneumatic swing mechanisms are provided and mounted on the base for positioning the workpiece.

[0008] Optionally, the pneumatic rocking mechanism includes a connecting seat fixedly mounted on the base, a support column connected to the connecting seat, and a pneumatic rocking rod mounted on the support column.

[0009] Optionally, the pneumatic rocker arm is connected to the support column via a rotating pin and a positioning buckle.

[0010] Optionally, a pressure head is provided on one side of the pneumatic rocker arm, the pressure head is configured to be screwed onto the pneumatic rocker arm with a self-threaded structure, and a locking nut is installed on the pressure head.

[0011] Optionally, the top cap is threaded and screwed onto the second support block.

[0012] Optionally, the second top pin is screwed onto the base via a bottom thread.

[0013] Optionally, the support column and the connecting seat are fixedly connected by screws.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This invention enables rapid clamping of workpieces by setting up a pneumatic swing mechanism and pneumatic control, thereby improving production efficiency. It is also simple and convenient to operate, reducing the labor intensity of operators and the daily tool usage time.

[0016] Furthermore, by setting up V-shaped positioning blocks and positioning cylinders, it can be applied to the processing of different models of sleeve aluminum parts, enhancing its versatility. The positioning method combining V-shaped positioning blocks and positioning cylinders improves the clamping accuracy and reduces the adverse effects of dimensional deviations caused by manual clamping by employees.

[0017] This invention improves upon existing tooling by designing a pneumatic positioning device for machining aluminum parts for motorcycle sleeves. Employees only need to press the start button to directly process the workpiece (eliminating the time required for manual clamping), thereby improving positioning accuracy and clamping efficiency.

[0029] Example

[0030] like Figure 1 and Figure 2 As shown, the present invention proposes a positioning device for machining aluminum parts for motorcycle sleeves, including a base 1 and a V-shaped positioning block 2 fixedly installed on the base 1. A first support block 3 and a second support block 5 are fixedly installed on one side of the V-shaped positioning block 2 on the base 1. A first top pin 4 is connected to the first support block 3, and a top cap 6 is provided on the second support block 5. The top cap 6 has its own thread and is screwed onto the second support block 5, which facilitates the disassembly and installation of the top cap 6 in the later stage.

[0031] In addition, a positioning cylinder 7 is installed on the side of the base 1 close to the second support block 5. A second top pin 8 is provided on one side of the positioning cylinder 7. The second top pin 8 is screwed onto the base 1 by the bottom thread. The positioning cylinder 7 is detachably connected to the base 1, such as by bolt connection, which facilitates the replacement of positioning cylinders of different specifications. It is suitable for processing different models of sleeve aluminum parts, which enhances versatility. The sleeve aluminum parts can be initially fixed on the base 1 by the first top pin 4, the second top pin 8, the positioning cylinder 7, the top cap 6 and the V-shaped positioning block 2. The V-shaped groove of the V-shaped positioning block 2 can naturally guide the center position of the workpiece, which can ensure that the workpiece is always in the correct position in the fixture. This self-centering function reduces the need for additional alignment devices, improves clamping speed and accuracy, and the device adopts a combination of a V-shaped positioning block 2 and a positioning cylinder 7 to ensure the coaxiality and perpendicularity of the sleeve aluminum parts and avoid repeated positioning. The base 1 is also equipped with equipment cylinders and other devices. The cylinder is existing technology and will not be described in detail here.

[0032] like Figures 2-4 As shown, the device also includes a pneumatic swing mechanism. There are two pneumatic swing mechanisms installed on the base 1 for positioning the workpiece. The pneumatic swing mechanism includes a connecting seat 9 fixedly installed on the base 1. A support column 10 is connected to the connecting seat 9. The support column 10 and the connecting seat 9 are fixedly connected by screws. The connecting seat 9 and the base 1 are also fixedly connected by screws, which makes it easier to replace and operate. A pneumatic swing rod 11 is installed on the support column 10.

[0033] Furthermore, the pneumatic rocker arm 11 is connected to the support column 10 via a rotating pin 13 and a positioning buckle 12. For the workpiece leg cantilever structure, an adjustable pin positioning structure is added. To address the issue of dimensional deformation in different batches, the height of the pin can be adjusted to hold the workpiece leg in place, making operation more convenient. The positioning buckle 12 is located at both ends of the rotating pin 13 and is used for positioning the pneumatic rocker arm 11 and the support column 10. The structure is simple and easier to replace.

[0034] Furthermore, a pressure head 15 is provided on one side of the pneumatic rocker arm 11. The pressure head 15 is designed to be screwed onto the pneumatic rocker arm 11 with a self-threaded structure. An additional thread is added to the top of the pressure head 15, and a locking nut 14 is installed on the pressure head 15. Because the pressure head 15 is screwed onto the pneumatic rocker arm 11 with its own thread, the addition of the locking nut 14 can prevent the pressure head 15 from loosening during long-term operation.

[0035] The working principle of this embodiment is as follows: The shot-blasted product workpiece is placed on the base 1, so that the first top pin 4 and the second top pin 8 in the workpiece abut against the lower end of the workpiece. At this time, a section of the head of the workpiece is locked and positioned in the V-groove of the V-shaped positioning block 2. With the positioning of the top cap 6 and the positioning cylinder 7, the workpiece is initially fixed on the base 1. Then, the employee presses the button, and the pneumatic rocker arm 11 is driven by the cylinder to move down and press down, so that the pressure head 15 clamps the workpiece, ensuring that the workpiece will not move during the processing. After the processing is completed, the cylinder and the pneumatic rocker arm 11 return to the initial position, and the workpiece is removed. This solves the problem of the employee having to tighten the tooling screws before each clamping, thus improving processing efficiency.

[0036] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
