Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a modular fixture for processing motorcycle switches. Background Technology

[0002] As a core component controlling the motorcycle's electrical system, the motorcycle switch typically comprises multiple parts, including a housing, contacts, and terminals. Its manufacturing process involves several key steps, such as blank forming, milling, drilling, surface treatment, and assembly. Drilling is a crucial step in ensuring the accuracy of subsequent assembly and the reliability of electrical connections. It requires machining multiple mounting holes and wiring holes of different diameters and depths at specific locations on the housing. This process usually necessitates the use of specialized fixtures to stably hold the workpiece, ensuring machining accuracy and a high product yield.

[0003] Currently, the motorcycle switch manufacturing industry generally uses traditional integrated fixtures with fixed clamping surface dimensions. However, with the diversification of motorcycle models and the increasing number of switch product specifications, this fixed clamping method and angle make it difficult to achieve comprehensive clamping according to different housing structures. This leads to uneven local stress on the workpiece during drilling, which can cause housing deformation or hole displacement, affecting product quality. Furthermore, poor versatility makes it difficult to adapt to small-batch, multi-variety production modes, failing to meet the requirements of modern manufacturing for equipment flexibility and economy. Utility Model Content

[0004] This utility model addresses the shortcomings of the prior art by providing a modular clamp for processing motorcycle switches that allows for easy replacement of the clamp type, thereby improving the versatility of the clamp and ensuring the clamping effect.

[0005] A modular fixture for processing motorcycle switches includes: a frame; a drilling machine fixedly connected to the frame for drilling holes in the housing; the fixture further includes: movable plates slidably connected to both sides of the frame, with a driving component at the rear of the frame connected to the two movable plates to control the movable plates to move closer or further apart; mounting seats fixedly connected to the two movable plates respectively; a contact panel fixedly connected to the mounting seats using an assembly structure, which is designed with different replacement bodies to adapt to the specific structure of the housing; a connecting block fixedly connected to the contact panel, with a corresponding groove on the mounting seat that matches the connecting block, the upper part of the groove passing through the mounting seat; and a magnetic block fixedly connected within the groove of the mounting seat, specifically disposed at the contact surface with the connecting block, and magnetically connected to the connecting block.

[0006] Optionally, the clamp further includes: a first rack and a second rack slidably connected within the mounting base, the two being arranged in parallel with their teeth facing opposite directions; a gear rotatably connected within the mounting base, which simultaneously meshes with the first rack and the second rack; an operating plate slidably connected to the outer surface of the mounting base, the bottom of which is fixedly connected to the second rack; a guide rod fixedly connected within the mounting base; and a top rod slidably connected to the guide rod, which is located at the bottom of the mounting base's sliding groove and fixedly connected to the first rack.

[0007] Optionally, the upper surface of the control panel is provided with friction texture to increase the contact friction between the operator's hand and the control panel when pressing.

[0008] Optionally, the clamp further includes a return spring fixedly connected between the operating plate and the mounting base.

[0009] Optionally, a guide surface is provided at the upper port of the slide groove on the mounting base, which is in the shape of an outwardly expanding horn.

[0010] Optionally, the clamp further includes a spacer fixedly connected to the contact surface between the contact panel and the housing, which has deformable characteristics.

[0011] Compared with existing technologies, this utility model has the following advantages: Through its replaceable contact panel design, this utility model allows for the selection of appropriate adaptable structures based on the specific shape and size of the housing. This ensures uniform force distribution across all parts of the housing during clamping, effectively preventing deformation and hole misalignment, and guaranteeing product quality.

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example: A modular fixture for machining motorcycle switches, such as... Figure 1 and Figure 2 As shown, it includes: a frame 1, which provides a stable working platform for this fixture; a drilling machine 2 fixedly mounted on the frame 1 for drilling the housing; movable plates 3 slidably mounted on both sides of the frame 1, with a double-headed cylinder at the rear of the frame 1 as the driving component, the two rod ends of which are respectively connected to the two movable plates 3, and the movable plates 3 are precisely controlled to move closer or further apart by controlling the extension and retraction of the rod ends of the double-headed cylinder; mounting bases 4 fixedly mounted on the two movable plates 3 respectively; and a contact panel 5 fixedly mounted on the mounting base 4 with an assembly structure, which is designed to adapt to the housing. Different replacements for the specific structure; the connecting block 6, which is fixedly installed on the contact panel 5, has a T-shaped cross-section. The mounting base 4 has a corresponding groove that matches the connecting block 6, and the upper part of the groove passes through the mounting base 4. During installation, the connecting block 6 of the contact panel 5 is aligned and inserted into the groove of the mounting base 4. The assembly and fixation of the contact panel 5 are achieved through the sliding cooperation between the connecting block 6 and the mounting base 4; the magnetic block 7, which is fixedly installed in the groove of the mounting base 4, is specifically set at the contact surface with the connecting block 6. It is magnetically connected to the connecting block 6 to achieve stable installation of the contact panel 5.

[0020] When drilling holes in a motorcycle shell, firstly, select a suitable contact panel 5 based on the shell's model and structure, and install it on the mounting base 4. Next, start the drive unit, and by manipulating the moving plates 3 on both sides to move closer together, the moving plates 3 drive the mounting base 4 and the contact panel 5 to move synchronously until the two contact panels 5 stably clamp the shell. At this point, operate the drilling machine 2 to drill holes in the shell. When it is necessary to clamp shells of different models or batches, simply remove the current contact panel 5 and replace it with a contact panel 5 suitable for the new shell, and repeat the above operation to complete the clamping and drilling of the new shell.

[0021] This fixture features a replaceable contact panel 5 design, allowing for the selection of appropriate adaptation structures based on the specific shape and size of the housing. This ensures uniform force distribution across all parts of the housing during clamping, effectively preventing deformation and hole misalignment, and guaranteeing product quality. Furthermore, using this fixture eliminates the need to replace the entire drilling device; simply replacing the contact panel 5 as needed enables efficient processing of different housings. This not only improves the fixture's versatility but also reduces production costs, meeting the demands of modern manufacturing for equipment flexibility and economy.

[0022] like Figures 1-4 As shown, it also includes: a first rack 8 and a second rack 10 slidably installed in the mounting base 4, which are arranged in parallel and have their teeth facing opposite directions; a gear 9 rotatably installed in the mounting base 4, which meshes with the first rack 8 and the second rack 10 at the same time to form a synchronous reverse transmission structure; an operating plate 11 slidably installed on the outer surface of the mounting base 4, the bottom of which is fixedly connected to the second rack 10; a guide rod 13 fixedly installed in the mounting base 4; and a top rod 12 slidably installed on the guide rod 13, which is located at the bottom of the sliding groove of the mounting base 4 and fixedly connected to the first rack 8.

[0023] When the contact panel 5 needs to be replaced, the operator presses down on the operating plate 11 on the outside of the mounting base 4. Through the reverse transmission between the first rack 8, the second rack 10 and the gear 9, the push rod 12 is moved upward. As the push rod 12 continues to support the connecting block 6 upward, the connecting block 6 gradually overcomes the attraction force of the magnetic block 7 under the action of the push force and slides upward along the slide groove until the connecting block 6 is completely separated from the top of the slide groove, thus completing the disassembly operation.

[0024] This fixture uses the push rod 12 to smoothly push the connecting blocks 6, while the auxiliary contact panel 5 smoothly and steadily detaches from the mounting base 4. The entire disassembly process is easy and convenient, greatly shortening the replacement time of the contact panel 5 and further enhancing the operational flexibility of this fixture.

[0025] like Figure 1 , Figure 2 and Figure 5As shown, the upper surface of the control panel 11 is provided with friction texture 14 to increase the contact friction between the operator's hand and the control panel 11 when pressing, to avoid slippage and ensure more stable and reliable operation of the control panel 11; the upper end of the slide groove on the mounting base 4 is provided with a guide surface 16, which is in the shape of an outwardly expanding horn mouth. By enlarging the initial mating surface between the connecting block 6 and the slide groove, the insertion direction of the connecting block 6 is precisely guided to assist the connecting block 6 in smoothly sliding into the slide groove, greatly reducing the installation difficulty of the contact panel 5 and improving operating efficiency; it also includes: a return spring 15 fixedly installed between the control panel 11 and the mounting base 4, used to automatically return the control panel 11 after the contact panel 5 is removed by pressing the control panel 11. The plate 11 is pushed upward to the initial position, preparing for the next installation or removal of the contact panel 5. No manual adjustment is required, which improves the ease of operation of this fixture by saving the reset step after operation. The spacer 17, which is fixedly installed on the contact surface between the contact panel 5 and the housing, has deformable characteristics. The spacer 17 adapts to the contact panel 5 when clamping the housing, so as to buffer the rigid clamping force of the contact panel 5 on the housing and avoid the housing from being indented or slightly deformed due to excessive local stress. In addition, the deformed spacer 17 will form a tighter fit with the surface of the housing, thereby increasing the friction between the contact panel 5 and the housing, further improving the clamping stability of the housing and ensuring drilling accuracy.

[0026] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
