Description

Technical Field

[0001] This utility model relates to the field of chassis processing technology, and in particular to a bending auxiliary device for chassis processing. Background Technology

[0002] In the field of chassis manufacturing, bending of metal sheets is one of the key forming processes. Traditional bending equipment often relies on manual positioning or fixed clamps for clamping, which is difficult to adapt to the need for rapid changeover of sheets of different sizes. This results in long adjustment times, low positioning accuracy, and high operational intensity. Furthermore, problems such as inaccurate bending angles and uneven springback can easily occur due to loose clamping or positioning deviations, affecting product consistency and processing efficiency. In addition, existing devices lack adaptive adjustment of sheet width and automatic clamping functions, making it difficult to meet the urgent needs of modern production for high-precision, high-efficiency, and automated processing. Therefore, we propose a bending auxiliary device for chassis processing. Utility Model Content

[0003] The main objective of this invention is to provide a bending auxiliary device for chassis processing, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A bending auxiliary device for chassis processing includes a base plate. An L-shaped support frame is integrally formed on the upper rear part of the base plate. A first electric telescopic rod is fixedly installed on the top of the L-shaped support frame. The output end of the first electric telescopic rod passes through the top of the L-shaped support frame and is fixedly connected to an L-shaped bending pressure block. A support platform is fixedly installed on the upper end of the base plate. A support mechanism is provided on the upper end of the support platform, and the support mechanism is located in front of the L-shaped bending pressure block.

[0006] The supporting mechanism includes a supporting platform, which is fixedly installed on the upper end of a support platform. Adjusting components are slidably connected to both the left and right sides of the supporting platform, and the two adjusting components are symmetrically distributed. A driving component is provided inside the supporting platform, and the two sides of the driving component are fixedly connected to the two adjusting components respectively.

[0007] Preferably, the adjustment assembly includes an L-shaped adjustment plate, with four connecting rods fixedly connected to the side of the L-shaped adjustment plate near the support platform. All four connecting rods are slidably connected to the support platform, and two positioning members are symmetrically connected to the top of the L-shaped adjustment plate.

[0008] By adopting the above technical solution: by using an L-shaped adjusting plate combined with a sliding connection of multiple connecting rods, the adjusting component can slide stably on the support platform while maintaining structural rigidity and guiding accuracy; the two positioning parts set on the top of the L-shaped adjusting plate are used to press and limit the two ends of the plate to prevent it from shifting or tilting during bending, thereby improving the overall processing stability and finished product quality.

[0009] Preferably, the upper surface of the lower part of the support platform is flush with the upper surface of the support platform.

[0010] By adopting the above technical solution, it is ensured that the board has a continuous and flat support surface when placed on the support platform, avoiding problems such as board deformation or inaccurate positioning due to height difference. At the same time, it is also conducive to the smooth sliding of the adjustment components, reducing frictional resistance, and improving adjustment accuracy and operational stability.

[0011] Preferably, the positioning component includes a fixing block, which is fixedly connected to the top of the L-shaped adjusting plate. A second electric telescopic rod is fixedly connected to the upper end of the fixing block, and the output end of the second electric telescopic rod passes through the fixing block and is fixedly connected to the positioning plate.

[0012] By adopting the above technical solution, the positioning plate is driven to move up and down using the No. 2 electric telescopic rod, which realizes the automatic clamping and release of the end of the plate, improving clamping efficiency and safety. At the same time, since the positioning component is directly integrated into the adjustment component, it can move synchronously with it, further enhancing the device's adaptability to plates of different sizes.

[0013] Preferably, the support platform has a transmission groove in the middle, and two sliding grooves communicating with the inside of the transmission groove are provided in the middle of the support platform, and the two sliding grooves are symmetrically distributed on the upper and lower sides of the transmission groove.

[0014] By adopting the above technical solution, a reasonable spatial layout and guiding path are provided for the drive components. The transmission groove is used to install the forward and reverse motors and drive gears, while the symmetrically arranged slide grooves provide a stable sliding track for the transmission body, ensuring that the adjustment components are subjected to uniform force and run smoothly during movement, thereby improving the rigidity and transmission accuracy of the overall mechanism.

[0015] Preferably, the drive assembly includes a forward and reverse motor and a transmission body. The forward and reverse motor is fixedly installed in the transmission groove, and a drive gear is fixedly connected to the output end of the forward and reverse motor. There are two transmission bodies, which are respectively fixedly connected to two L-shaped adjustment plates. The two transmission bodies are slidably connected in two sliding grooves and are connected to the drive gear for transmission.

[0016] By adopting the above technical solution, the drive gear is rotated by the forward and reverse motors and meshes with the transmission racks on the two transmission bodies to realize the synchronous reverse movement of the two adjustment components, thereby completing the automatic adjustment of the spacing. The whole process does not require manual intervention, has a fast response speed and high control precision, and greatly improves the automation level and ease of use of the equipment.

[0017] Preferably, the transmission body includes a slide bar, which is slidably connected in a slide groove and has one end fixedly connected to an L-shaped adjusting plate. A transmission rack is fixedly connected to the end of the slide bar near the drive gear, and the transmission rack meshes with the drive gear.

[0018] By adopting the above technical solution, the guiding function is achieved through the cooperation of the slide bar and the slide groove, and the power transmission is achieved through the meshing of the transmission rack and the drive gear. This ensures the stability and synchronization of the adjustment component during the movement process. The transmission method has a compact structure and high transmission efficiency, and is suitable for industrial production scenarios with frequent adjustments, and has good application prospects.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By setting a sliding adjustable component on the support platform and combining it with positioning components to clamp and fix the sheet metal, the stability and positioning accuracy during the bending process are significantly improved. Specifically, the two L-shaped adjusting plates can move synchronously in opposite directions according to the actual width of the sheet metal to be processed, thereby automatically adjusting to the appropriate spacing position. Then, the positioning plate is driven down by the No. 2 electric telescopic rod to firmly fix the sheet metal above the support platform. This automated and precise clamping method effectively prevents forming deviations caused by sheet metal displacement or vibration during the bending process, ensuring the dimensional consistency and appearance quality of the product. It is especially suitable for the needs of large-volume, high-precision chassis sheet metal processing.

[0021] 2. The drive assembly adopts a transmission structure combining forward and reverse motors, drive gears, and transmission racks, achieving efficient and stable drive control for the two adjustment components. The forward and reverse motors drive the drive gears to rotate, which in turn drives the transmission racks on both sides to move synchronously in opposite directions, enabling the two adjustment components to quickly and accurately complete the spacing adjustment. This transmission method is not only compact and runs smoothly, but also has a fast response speed and high control precision, avoiding the errors and time-consuming problems caused by traditional manual adjustment. At the same time, the guiding cooperation between the slide bar and the slide groove further enhances the rigidity and stability of the entire adjustment mechanism, ensuring that there is no deviation or jamming during the transmission process. This significantly improves the ease of operation, repeatability, and overall automation level of the equipment, making it suitable for the dual requirements of efficiency and precision in modern intelligent manufacturing.

[0030] Please see Figure 1-4 This utility model provides a technical solution:

[0031] A bending auxiliary device for chassis processing includes a base plate 1. An L-shaped support frame 2 is integrally formed on the upper rear part of the base plate 1. A first electric telescopic rod 5 is fixedly installed on the top of the L-shaped support frame 2. The output end of the first electric telescopic rod 5 passes through the top of the L-shaped support frame 2 and is fixedly connected to an L-shaped bending pressure block 6. A support platform 3 is fixedly installed on the upper end of the base plate 1. A support mechanism 4 is provided on the upper end of the support platform 3, and the support mechanism 4 is located in front of the L-shaped bending pressure block 6.

[0032] In this embodiment, the supporting mechanism 4 includes a supporting platform 41, which is fixedly installed on the upper end of the support platform 3. Adjusting components 42 are slidably connected to both the left and right sides of the supporting platform 41, and the two adjusting components 42 are symmetrically distributed. A driving component 43 is provided inside the supporting platform 41, and both sides of the driving component 43 are fixedly connected to the two adjusting components 42 respectively. The adjusting component 42 includes an L-shaped adjusting plate 421, and four connecting rods 422 are fixedly connected to the side of the L-shaped adjusting plate 421 near the supporting platform 41. All connecting rods 422 are slidably connected to the support platform 41. Two positioning parts 423 are symmetrically connected to the top of the L-shaped adjusting plate 421. The upper end face of the lower part of the support platform 41 is flush with the upper end face of the support platform 41. The positioning part 423 includes a fixing block 4231, which is fixedly connected to the top of the L-shaped adjusting plate 421. A second electric telescopic rod 4232 is fixedly connected to the upper end of the fixing block 4231. The output end of the second electric telescopic rod 4232 passes through the fixing block 4231 and is fixedly connected to the positioning plate 4233.

[0033] With the above scheme: after the positions of the two adjustment components 42 are adjusted, the metal sheet to be bent is placed on the support platform 41, with both ends of it located at the top of the lower part of the two L-shaped adjustment plates 421. At this time, the second electric telescopic rod 4232 is activated, and its output end pushes the positioning plate 4233 downward, so that the positioning plate 4233 presses the two ends of the sheet, ensuring that the sheet will not be displaced or shifted during the subsequent bending process, thereby improving the processing accuracy.

[0034] In this embodiment, a transmission groove 412 is formed in the center of the support platform 41, and two sliding grooves 411 communicating with the interior of the transmission groove 412 are formed in the center of the support platform 41. The two sliding grooves 411 are symmetrically distributed on the upper and lower sides of the transmission groove 412. The drive assembly 43 includes a forward and reverse motor 431 and a transmission body 433. The forward and reverse motor 431 is fixedly installed in the transmission groove 412, and a drive gear 432 is fixedly connected to the output end of the forward and reverse motor 431. The transmission body 433 is provided with two... Each of the two transmission bodies 433 is fixedly connected to two L-shaped adjusting plates 421 respectively, and is slidably connected to two slide grooves 411 and is connected to the drive gear 432. The transmission body 433 includes a slide bar 4331, which is slidably connected to the slide groove 411 and fixedly connected to the L-shaped adjusting plate 421 at one end. A transmission rack 4332 is fixedly connected to the end of the slide bar 4331 near the drive gear 432, and the transmission rack 4332 is meshed with the drive gear 432.

[0035] The above scheme is as follows: the distance between the two adjustment components 42 is adjusted by the drive component 43. After the forward and reverse motor 431 is started, it drives the drive gear 432 to rotate. The drive gear 432 meshes with the two transmission racks 4332, thereby driving the two slide bars 4331 to make linear movements in opposite directions in the slide groove 411, which in turn drives the two L-shaped adjustment plates 421 to move synchronously in opposite directions, thereby realizing the automatic adjustment of the distance between the two adjustment components 42.

[0036] It should be noted that this utility model is a bending auxiliary device for chassis processing. Before bending, the distance between the two adjusting components 42 is adjusted according to the width of the sheet metal to be processed by the drive component 43. After the forward and reverse motor 431 is started, it drives the drive gear 432 to rotate. The drive gear 432 meshes with the two transmission racks 4332, thereby driving the two slide bars 4331 to move in opposite directions in the slide groove 411, which in turn drives the two L-shaped adjusting plates 421 to move synchronously in opposite directions, realizing the automatic adjustment of the distance between the two adjusting components 42. After the positions of the two adjusting components 42 are adjusted, the metal sheet to be bent is placed on the support platform 41, with its two ends located at the top of the lower part of the two L-shaped adjusting plates 421. At this time, the second electric telescopic rod 4232 is started, and its output... The first end pushes the positioning plate 4233 downward, pressing the two ends of the plate together to ensure that the plate will not shift or deviate during subsequent bending, thereby improving processing accuracy. After the plate is fixed, the first electric telescopic rod 5 is activated, and its output end drives the L-shaped bending block 6 downward. The L-shaped bending block 6 contacts the plate on the support platform 3 and applies pressure, causing the plate to undergo plastic deformation at the set position, completing the bending operation. Since the plate has been precisely positioned and clamped, the bending angle and size are more accurate, reducing the need for manual intervention and repeated adjustments. After bending, the first electric telescopic rod 5 is reset, and the L-shaped bending block 6 rises and detaches from the plate. At the same time, the second electric telescopic rod 4232 drives the positioning plate 4233 to rise and release the plate. Then, the finished product can be taken out or a new plate to be processed can be placed in, and the above process can be repeated.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
