[0002] Since its application in automotive powertrain systems in the late 1980s, the dual-mass flywheel has been widely adopted in Europe, extending from high-end cars to mid-range cars. It is particularly suitable for diesel engines because diesel engines vibrate more than gasoline engines.

[0003] In the machining of dual-mass flywheels, the surface is usually machined. Traditional clamping methods have blind spots, which can cause the flywheel to shift or deform during machining, thus affecting machining accuracy and product quality.

[0004] Based on this, a positioning structure for flywheel machining is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] To address the aforementioned issues, a positioning structure for flywheel machining is provided, which solves the problem of blind spots in flywheel positioning through a positioning mechanism and a clamping mechanism.

The other end of the limiting block is located inside the base, and the moving block is slidably arranged inside the limiting block. A clamping mechanism is provided on the side wall of the moving block.

[0008] Preferably, the clamping mechanism includes a mounting plate and a clamping block, the mounting plate is mounted on the side wall of the movable block, and the clamping block is mounted on the other side wall of the mounting plate.

The limiting ring has threads that cooperate with the lead screws. A button block is provided at the end of the lead screw away from the flywheel body. The end of the lead screw close to the flywheel body is rotatably engaged with the inner wall of the positioning block. A sliding block is provided on the bottom wall of the positioning block. The sliding block is slidably mounted inside the limiting block.

[0010] Preferably, the button block has a handle on its side wall.

[0011] Preferably, the positioning block has a protective layer on the side closest to the flywheel body.

Detailed Implementation

[0021] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-4 A positioning structure for flywheel processing includes a base 101, a support platform 102 above the base 101, a plurality of sliding grooves 103 symmetrically arranged on the support platform 102, a limiting ring 105 on the side wall of the support platform 102, a clamping mechanism 400 for clamping and fixing the positioning hole at the center of the flywheel body 104 at the middle position of the sliding groove 103, a driving mechanism 200 for driving the clamping mechanism 400 to clamp between the base 101 and the support platform 102, and a plurality of positioning mechanisms 300 symmetrically arranged on the limiting ring 105.

[0023] The drive mechanism 200 is used to drive the clamping mechanism 400 to clamp and push the inner wall of the positioning hole at the center of the flywheel body 104, which can avoid the existence of a clamping blind spot. By setting the positioning mechanism 300, the outer wall of the flywheel body 104 can be further limited, which plays a further stabilizing role. Moreover, there are multiple sets of such positioning mechanisms 300. When there is an obstruction, the positioning position can be unlocked and changed to avoid the existence of a clamping blind spot.

[0024] Reference Figures 1-3 The drive mechanism 200 includes a motor 201, a positioning column 202, a rotating block 203, a rotating arm 204, a moving block 205, and a limiting block 206. The motor 201 is installed inside the base 101. The output end of the motor 201 passes through the side wall of the base 101 and connects to the positioning column 202. The positioning column 202 has a rotating block 203 on its outer wall. Several rotating arms 204 are rotatably arranged between the inner walls of the rotating block 203. The other end of the rotating arm 204 is hinged to the side wall of the moving block 205. The bottom wall of the support platform 102 has a limiting block 206 that cooperates with the sliding groove 103. The other end of the limiting block 206 is located inside the base 101. The moving block 205 is slidably arranged inside the limiting block 206. Each side wall of the moving block 205 is provided with a clamping mechanism 400.

[0025] The start motor 201 drives the positioning column 202 and the rotating block 203 to rotate, which in turn drives the rotating arm 204 to rotate. Through their cooperation, the moving block 205 can move back and forth on the limit block 206, achieving the effect of pushing, fixing and unlocking.

[0026] Reference Figures 1-4 The clamping mechanism 400 includes a mounting plate 401 and a clamping block 402. The mounting plate 401 is mounted on the side wall of the moving block 205, and the clamping block 402 is mounted on the other side wall of the mounting plate 401.

[0027] The moving block 205 moves on the limiting block 206, which drives the mounting plate 401 to push the clamping block 402 to perform the work of pushing and clamping the inner wall of the positioning hole of the flywheel body 104. Similarly, when unlocking is required, the mounting plate 401 drives the clamping block 402 to reset so that it can be unlocked.

[0028] Reference Figures 1-2 The positioning mechanism 300 includes a positioning block 301, a lead screw 302, a button block 303, and a sliding block 304. A plurality of lead screws 302 are rotatably mounted on the limiting ring 105. The limiting ring 105 has threads that cooperate with the lead screws 302. The end of the lead screw 302 away from the flywheel body 104 is provided with a button block 303. The end of the lead screw 302 close to the flywheel body 104 is rotatably engaged with the inner wall of the positioning block 301. The bottom wall of the positioning block 301 is provided with a sliding block 304, which is slidably disposed within the limiting block 206.

[0029] Rotating the knob 303 drives the lead screw 302 to rotate. The lead screw 302 cooperates with the limiting ring 105 to move back and forth on the limiting ring 105, thereby driving the sliding block 304 to slide within the limiting block 206. The sliding block 304 drives the positioning block 301 to position the outer wall of the flywheel body 104. This positioning can be changed at any time to avoid the existence of clamping blind spots.

[0030] Reference Figures 1-2 The button block 303 has a handle on its side wall.

[0031] This handle facilitates the rotation of the button block 303.

[0032] Reference Figures 1-4 The positioning block 301 has a protective layer on the side near the flywheel body 104.

[0033] To avoid damage to the flywheel body 104 during the clamping and fixing process of the positioning block 301.

[0034] Reference Figures 1-4 The clamping block 402 has a soft pad on the side near the positioning hole of the flywheel body 104.

[0035] The soft pad is used to reduce the damage and friction caused by the clamping block 402 clamping the flywheel body 104.

[0036] Working principle: The positioning hole on the flywheel body 101 is passed through the positioning post 202. The motor 201 is started, which drives the positioning post 202 and the rotating block 203 to rotate, which in turn drives the rotating arm 204 to rotate. Through their cooperation, the moving block 205 can move back and forth on the limiting block 206. The movement of the moving block 205 on the limiting block 206 drives the mounting plate 401 to push and clamp the clamping block 402 to fix the inner wall of the positioning hole of the flywheel body 104. When unlocking is required, the mounting plate 401 drives the clamping block 402 to reset. To unlock it, the clamping position is the positioning hole at the center of the flywheel 104, eliminating any clamping blind spots during surface processing. Rotating the knob 303 drives the lead screw 302 to rotate, and the lead screw 302 moves back and forth on the limit ring 105 through its cooperation with the limit ring 105. This allows the sliding block 304 to slide within the limit block 206, and the sliding block 304 drives the positioning block 301 to position the outer wall of the flywheel body 104. This positioning allows for easy repositioning, avoiding any clamping blind spots.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
