Detailed Implementation

[0035] To enhance understanding of this utility model, it will be further described in detail below with reference to embodiments and accompanying drawings. This utility model can be implemented in the following ways:

[0036] Reference Figure 1-9An adjustable fixing device for processing motorcycle engine housings includes a fan-shaped base 1 and a positioning mechanism 2, a clamping mechanism 3, an error-proofing mechanism 4, and a control switch 5 that controls the operation of the clamping mechanism 3 and the error-proofing mechanism 4, all detachably mounted on the base 1. The positions of the positioning mechanism 2, the clamping mechanism 3, and the error-proofing mechanism 4 can be finely adjusted according to the shape of the motorcycle engine housing (hereinafter referred to as the housing), making it suitable for processing various models of housings 6, thus having a wide range of applications; and eliminating the need to develop new tooling, saving production costs.

[0037] Specifically, the positioning mechanism 2 includes several horizontal limiting members 21 detachably mounted on the base 1 and several support columns 22 for supporting the mounting post holes of the outer shell 6. Each horizontal limiting member 21 includes a limiting rubber block 211 and a mounting post 212 located at the bottom of the limiting rubber block 211. The limiting rubber block 211 has an irregular limiting surface 213 on the side in contact with the outer shell 6, conforming to the shape of the outer edge of the outer shell 6, allowing it to fit snugly against the outer edge of the outer shell 6. This embodiment provides three horizontal limiting members 21 in different directions, preventing horizontal wobbling of the outer shell 6 during processing, thus ensuring processing accuracy. The limiting rubber block 211 and the mounting post 212 are detachably connected. In this embodiment, the limiting rubber block 211 and the mounting post 212 are detachably connected by a screw. When processing other models of outer shell 6, the corresponding model of the limiting rubber block 211 can be replaced, making the operation simple and quick. The number of support columns 22 is required to ensure that the entire outer shell 6 is supported, preventing the surface of the outer shell 6 from contacting the base 1, thereby preventing the surface of the outer shell 6 from being scratched during the processing.

[0038] To prevent the outer casing 6 from swaying up and down during processing, the clamping mechanism 3 includes several movable clamping components 31 detachably mounted on the base 1 and a clamping drive source 32 that controls the movable clamping components 31 to clamp or release the outer casing 6. Each movable clamping component 31 includes a mounting base 311 and a movable block 312 hinged to the top of the mounting base 311. One side of the movable block 312 is hinged to the clamping drive source 32. The clamping drive source 32 includes a pull rod 321 and a clamping cylinder 322 that controls the raising and lowering of the pull rod 321. The free end of the pull rod 321 is hinged to one side of the movable block 312. During operation, the clamping cylinder 322 pushes the pull rod 321 upward, and the movable block 312, under the action of leverage, presses down to the top of the outer casing 6, cooperating with the support column 22 to clamp the outer casing 6, preventing it from swaying vertically during processing and ensuring processing accuracy. Furthermore, an adjustment seat 33 is provided on the side of the movable clamping assembly 31, and a support rod 331 is movably mounted on the adjustment seat 33. A cylinder for controlling the raising and lowering of the support rod 331 is connected to the bottom of the support rod 331. This design can be used for auxiliary fixation of the outer shell 6 with its top edge protruding outward.

[0039] Since the outer casing 6 generally has at least one through-hole 61 that penetrates the outer casing 6 itself (e.g. Figure 10 As shown, the position of the mounting through hole 61 is different for each model. To prevent incorrect processing of the housing 6 model, the position of the error-prevention mechanism corresponds to the position of the mounting through hole 61 of the corresponding housing 6 model. The error-prevention mechanism 4 includes several error-prevention bases 41 detachably mounted on the base 1, a limiting rod 42 that movably passes through the error-prevention base 41, a limiting pressure block 43 movably sleeved on the limiting rod 42, and an error-prevention drive source 44 that drives the limiting rod 42 to rise and fall. Using the error-prevention drive source 44, the height of the limiting rod 42 can be adjusted to adapt to the position requirements of the mounting through hole of different housing 6 models. The error-prevention drive source 44 is a cylinder. The top of the limiting rod 42 is provided with a limiting cap 421, and the limiting rod 42 is recessed below the limiting cap 421 to form a clearance recess 422 for the limiting pressure block 43 to engage. The limiting pressure block 43 is provided with a notch 431 for easy insertion into the clearance recess 422. The limiting pressure block 43 is a ring with a notch. Before processing, the limiting block 43 needs to be removed, and then the outer shell 6 of the corresponding processing model needs to be placed on the fixing device. Then, the limiting block 43 is inserted into the limiting rod 42 and pressed tightly. This design can also play an auxiliary limiting role.

[0040] To facilitate operation by staff, the control switch 5 includes a control base 51 and a crank switch 52 located on top of the control base 51. By rotating the handle, the operator can control the clamping mechanism 3 to release or clamp the outer casing 6, so as to remove or place the outer casing 6.

[0041] To allow for fine-tuning of the positioning mechanism 2, clamping mechanism 3, and error-proofing mechanism 4, the base 1 is provided with several mounting holes 11 for adjusting the positions of the positioning mechanism 2, clamping mechanism 3, and error-proofing mechanism 4. Since the positioning mechanism 2, clamping mechanism 3, and error-proofing mechanism 4 are all detachable, when processing other models of housing 6, it is only necessary to adjust the positions of the positioning mechanism 2, clamping mechanism 3, and error-proofing mechanism 4, or to disassemble a portion of them.

[0042] In order to ensure that the fixing device can be installed stably on the processing equipment, the bottom of the base 1 is provided with a mounting block 12 for mounting the entire fixing device on the disc milling machine and several pads 13 for supporting the base 1, so that the entire fixing device can be kept in a horizontal state.

[0043] Because the base 1 has a fan-shaped design, it can be evenly distributed around the circumference of the disc milling machine, and its installed state is as follows: Figure 9As shown, this design not only allows for simultaneous processing of multiple operations, but also provides operators with sufficient time to handle the outer casing 6 during the machining process of the disc milling machine. Furthermore, the energy consumption of disc milling machines is significantly lower than that of vertical milling machines, further reducing enterprise production costs. The adjustable fixing device in this embodiment can be used simultaneously for machining three types of outer casing 6. Statistics show that after this fixing device was implemented in production, it reduced the need for one vertical milling machine, increased production efficiency by 15%, reduced employee workload by 20%, improved production quality, and saved 37,000 kWh of electricity annually, making it suitable for widespread application and promotion.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
