Description

Technical Field

[0001] This utility model belongs to the field of automotive splash pad processing technology, and specifically relates to a punching tool for splash pad processing. Background Technology

[0002] A splash guard is a protective accessory for automobiles, typically made of materials such as rubber and plastic. It possesses a certain degree of flexibility and durability. It is mainly installed behind the tires and on specific parts of the underside of the vehicle. Its primary function is to effectively prevent mud, water, sand, and other debris splashed up by the tires from directly hitting the sides, bottom, and other parts of the vehicle when driving on muddy roads, flooded surfaces, or gravel areas, keeping the vehicle clean. At the same time, splash guards can also reduce the impact and wear of these debris on the paint surface, lowering the risk of corrosion caused by long-term erosion from mud, water, sand, etc., and extending the vehicle's lifespan to some extent. In addition, splash guards are relatively easy to install and can be customized according to different vehicle models, providing car owners with a practical and economical option for vehicle protection.

[0003] Currently, in the processing of automotive splash guards, it is usually necessary to drill holes in the top of the pad. However, existing pad drilling equipment has certain defects in application. For example, Chinese patent with announcement number "CN216152539U" discloses an automotive sound insulation pad punching device. The punching device adopts a first slide rail and a second slide rail, which solves the problems of existing automotive sound insulation pad punching devices requiring the sound insulation pad to be moved to change the punching position during use, and the different drilling depths of different sound insulation pads making the operation of the device cumbersome and time-consuming, resulting in low operator efficiency.

[0004] While the aforementioned device possesses certain drilling capabilities in practical applications, it lacks a stable and effective positioning structure during drilling. This results in the inability to achieve stable positioning and transmission when drilling pad materials. For example, in the processing of automotive splash guards, the lack of such a positioning structure prevents flexible adjustment of left and right displacement, thus hindering free drilling at any position on the splash guard. Consequently, manual adjustments are often required during production, significantly reducing production efficiency and increasing labor costs. Furthermore, this situation prevents the device from achieving continuous and uninterrupted production, severely impacting overall production progress and efficiency. Overall, the device exhibits certain defects and shortcomings during use, urgently requiring improvement and refinement to meet the demands of efficient and precise production. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a punching fixture for processing splash pads, so as to solve the problem that the existing equipment cannot flexibly adjust the lateral position of the splash pad during processing, resulting in poor processing adaptability and inconvenience for continuous and uninterrupted production.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A punching fixture for processing splash-proof pads includes a mounting frame. The inner ends of the mounting frame are rotatably connected to conveying guide rollers at equal intervals. A lifting mechanism is fixedly installed in the middle of the outer side of the mounting frame. A transverse movement mechanism is fixedly installed in the inner side of the lifting mechanism.

[0008] The lifting mechanism includes a vertical rail, which is fixedly installed on the middle of both sides of the mounting frame. A first motor is fixedly installed at the bottom of the vertical rail. A lead screw is fixedly installed through the output end of the first motor through the vertical rail. A slider is threadedly connected to the outer surface of the lead screw. A slider is slidably connected to the inner side of the other vertical rail.

A gear is fixedly installed through the side connecting arm at the output end of the second motor. The rack is fixedly installed on one side of the horizontal rail, and the rack and gear are meshed together.

[0011] As a preferred technical solution, the drilling mechanism includes an electric push rod, which is fixedly installed on the top of the mounting base. The bottom output end of the electric push rod passes through the mounting base and the movable block and is fixedly installed with a connecting rod. The bottom of the connecting rod is fixedly installed with a fixed base. The bottom of the fixed base is fixedly installed with a third motor. The output end of the third motor is fixedly installed with a drilling bit.

[0012] As a preferred technical solution, the inner cross-sectional shape of both the slider and the vertical rail is set to a convex shape, and wear-resistant pads are fixedly connected to the outer surface of the slider and the inner wall of the vertical rail.

[0013] As a preferred technical solution, the driving mechanism includes a crossbar, which is fixedly installed at the bottom of the connecting arm. Both ends of the inner side of the crossbar are rotatably connected to a driving roller, and both ends of the outer side of one crossbar are fixedly installed with a fourth motor.

[0015] In summary, the present invention has the following main advantages:

[0016] First, this device is equipped with a lifting mechanism. During use, the first motor can be started to drive the lead screw to rotate, causing the slider to slide within the vertical rail. This, in turn, drives the horizontal movement mechanism, drilling mechanism, and drive mechanism to move up and down, allowing the drive roller to fit against the splash pad. The fourth motor is then started to drive the roller to rotate, causing the splash pad to move laterally between the drive roller and the conveying guide roller. This allows for drilling and adjustment of the splash pad's position. After drilling, the finished splash pad can be discharged, and unfinished pads can be filled in for further processing, enabling continuous and uninterrupted production. This improves the device's adaptability and allows for flexible adjustment of the splash pad's position for drilling, making it suitable for drilling needs in different locations.

[0017] Third, this device is equipped with a drilling mechanism and a transverse movement mechanism, which allows the device to drive the gear to rotate by starting the second motor during use. Because the gear meshes with the rack, the movable block slides in the transverse rail to adjust the transverse position of the electric push rod. With the help of the drive roller, it can drill holes in any position of the splash pad in both the transverse and longitudinal directions. The height of the third motor can be changed by using the electric push rod to adjust the height of the drilling bit. Starting the third motor realizes automated drilling, which improves drilling efficiency and quality. The device has strong overall processing adaptability, is convenient and efficient to use, and is worth promoting. Attached Figure Description

Detailed Implementation

[0023] Example

[0024] refer to Figures 1 to 4 The punching fixture for processing splash pads in this embodiment includes a mounting frame 1. The inner two ends of the mounting frame 1 are rotatably connected with conveying guide rollers 2 at equal intervals. A lifting mechanism 3 is fixedly installed in the middle of the outer side of the mounting frame 1. A transverse movement mechanism 4 is fixedly installed in the inner side of the lifting mechanism 3. A drilling mechanism 5 is fixedly installed in the inner side of the transverse movement mechanism 4. A drive mechanism 6 is fixedly installed on both sides of the bottom of the transverse movement mechanism 4.

[0025] The lifting mechanism 3 includes a vertical rail 31, which is fixedly installed on the middle of both sides of the mounting frame 1. A first motor 32 is fixedly installed at the bottom of the vertical rail 31. A lead screw 33 is fixedly installed through the output end of the first motor 32 through the vertical rail 31. A slider 34 is threadedly connected to the outer surface of the lead screw 33. A slider 34 is slidably connected to the inner side of the other vertical rail 31. The inner side of the slider 34 is fixedly connected to the transverse movement mechanism 4. The conveying guide roller 2 on the inner side of the mounting frame 1 can realize the stable conveying of the splash pad. The vertical rail 31 in the lifting mechanism 3 provides support for various components. To ensure a stable installation position, the first motor 32 drives the lead screw 33 to rotate, causing the slider 34 to slide up and down within the vertical rail 31. This, in turn, causes the transverse mechanism 4, drilling mechanism 5, and drive mechanism 6 to move up and down, allowing for flexible position adjustments to adapt to the processing requirements of splash guards of different sizes. This design enables the drive roller 62 of the drive mechanism 6 to precisely fit the outer surface of the splash guard, improving processing stability and accuracy. At the same time, the overall structure is compact, and the various mechanisms work together to achieve efficient and continuous splash guard punching, thus improving production efficiency.

[0026] refer to Figure 4The transverse mechanism 4 includes a connecting arm 41, which is fixedly installed on the inner side of the slider 34. A horizontal rail 42 is fixedly installed on the upper inner side of the connecting arm 41. A power assembly 43 is slidably connected to the inner side of the horizontal rail 42. A drilling mechanism 5 is installed on the power assembly 43. A drive mechanism 6 is fixedly installed on the bottom of the connecting arm 41. The power assembly 43 includes a movable block 431 and a rack 432. The movable block 431 is slidably connected to the inner side of the horizontal rail 42. A mounting base 433 is fixedly installed on the top of the movable block 431. The drilling mechanism 5 is connected to the mounting base 433. A side connecting arm 434 is fixedly installed on the outer side of the mounting base 433. A second motor 435 is fixedly installed on the outer side of the side connecting arm 434. A gear 436 is fixedly installed through the output end of the second motor 435 through the side connecting arm 434. The rack 432 is fixedly installed on the horizontal rail 434. On one side of 2, rack 432 and gear 436 are meshed and connected. Connecting arm 41 connects slider 34 to horizontal rail 42 to ensure structural stability. Horizontal rail 42 provides a moving track for power component 43. Movable block 431 slides flexibly and smoothly within horizontal rail 42. Mounting seat 433 facilitates the installation and connection of drilling mechanism 5, making position adjustment of drilling mechanism 5 more convenient. Second motor 435 on side connecting arm 434 drives gear 436 to rotate. Since gear 436 is meshed with rack 432, it can accurately drive movable block 431 to slide within horizontal rail 42, thereby driving drilling mechanism 5 to move laterally. This design can flexibly adjust the lateral position of drilling mechanism 5 according to the processing requirements of splash pad, realizing precise drilling processing at any position on the top of splash pad, improving processing adaptability and efficiency.

[0027] refer to Figures 1-4The drilling mechanism 5 includes an electric push rod 51, which is fixedly installed on the top of the mounting base 433. A connecting rod 52 is fixedly installed at the bottom output end of the electric push rod 51, passing through the mounting base 433 and the movable block 431. A fixed base 53 is fixedly installed at the bottom of the connecting rod 52, and a third motor 54 is fixedly installed at the bottom of the fixed base 53. A drilling bit 55 is fixedly installed at the output end of the third motor 54. The inner cross-sectional shape of the slider 34 and the vertical rail 31 is both convex. Wear-resistant pads are fixedly connected to the outer surface of the slider 34 and the inner wall of the vertical rail 31. The drive mechanism 6 includes a crossbar 61, which is fixedly installed at the bottom of the connecting arm 41. Drive rollers 62 are rotatably connected to both ends of the inner side of the crossbar 61. A fourth motor 63 is fixedly installed at both ends of the outer side of one crossbar 61. The output end of the fourth motor 63 is fixedly connected to one end of the drive roller 62. Support legs 7 are fixedly installed at the four corners of the bottom of the mounting frame 1. A bearing base frame 8 is fixedly installed at the bottom of the support legs 7. In the drilling mechanism 5, the electric push rod 51 can push the fixed seat 53 at the bottom of the connecting rod 52 and the third motor 54 to move up and down, thereby adjusting the height of the drilling bit 55. The third motor 54 drives the drilling bit 55 to realize automated drilling, which improves drilling efficiency and quality. The convex cross-section design of the slider 34 and the vertical rail 31 and the setting of wear-resistant pads ensure the stability and wear resistance of the lifting process. The crossbar 61 of the drive mechanism 6 is connected to the rotatable drive roller 62. The fourth motor 63 provides power to the drive roller 62, which can drive the splash pad to move laterally between the conveying guide roller 2 and the drive roller 62, so as to flexibly adjust the position of the splash pad for drilling. The support legs 7 and the bearing base frame 8 at the bottom of the mounting frame 1 provide stable support for the entire device.

[0028] Operating principle and advantages: By setting up the lifting mechanism 3, during actual use, the device can drive the lead screw 33 to rotate by starting the first motor 32. As the lead screw 33 rotates, it can drive the slider 34 to slide on the inner side of the vertical rail 31. During the up-and-down sliding of the slider 34 on the inner side of the vertical rail 31, it can simultaneously drive the horizontal movement mechanism 4, the drilling mechanism 5, and the drive mechanism 6 to move up and down. At this time, it can cause the drive roller 62 of the drive mechanism 6 to come into contact with the outer surface of the splash pad, so that the splash pad is located between the inner side of the conveyor belt roller and the drive roller 62. When the drive roller 62 at the bottom of the crossbar 61 contacts the outer surface of the conveyor guide roller 2, the fourth motor 63 can be started to drive the drive roller 62 to rotate. After the drive roller 62 rotates, The device can drive the splash pad to move laterally between the drive roller 62 and the conveying guide roller 2. During this process, drilling can be performed by the drilling mechanism 5. By adjusting the rotation direction of the fourth motor 63, the tightness and lateral position of the splash pad at the bottom of the drive roller 62 can be adjusted very flexibly. After the drilling is completed, the drilled splash pad can be discharged by the drive of the transmission guide roller and the drive roller 62. Unprocessed splash pads can be filled between the drive roller 62 and the conveying guide roller 2 from one side for further processing. It can be seen that this equipment can achieve continuous and uninterrupted processing, and at the same time, the position of the splash pad can be flexibly adjusted to facilitate drilling at different positions on the splash pad, which greatly improves the overall adaptability of the device.

[0029] By setting up the drilling mechanism 5 and the transverse movement mechanism 4, if the longitudinal position of the drilling mechanism 5 needs to be adjusted during use, the second motor 435 can be started. The second motor 435 can drive the gear 436 to rotate. Since the gear 436 and the rack 432 are meshed, the movable block 431 can be driven to slide inside the transverse rail 42. By sliding the movable block 431, the transverse position of the electric push rod 51 can be adjusted. At this time, in conjunction with the adjustment of the anti-splash pad by the drive roller 62, the function of horizontal and vertical drilling can be realized at any position on the top of the anti-splash pad. The overall processing performance is stronger. In addition, during the drilling process, the electric push rod 51 pushes the third motor 54 on the bottom fixed seat 53 of the connecting rod 52 to move up and down, thereby changing the drilling height of the drill bit 55. At this time, starting the third motor 54 can realize automated drilling, which can further improve the overall drilling efficiency and quality of the equipment. The overall application of this equipment is more convenient and efficient, and it is indeed worth promoting and applying.
