Abstract

This invention discloses a deflection compensation device for easy fixation of a worktable, comprising a base, a worktable plate horizontally arranged above the base, and a bottom plate fixedly connected below. The base has a compensation adjustment groove along its entire length, a deflection compensation mechanism disposed within the compensation adjustment groove, and a balance locking mechanism evenly distributed on both sides of the compensation adjustment groove and mounted on the base. The balance locking mechanism maintains the relative positions of the base, worktable plate, and vertical insert plate. During the bending process of a workpiece placed on the worktable plate, this invention compensates for the downward deflection of the worktable plate through the deflection compensation mechanism. Under the action of the balance locking mechanisms on both sides of the compensation groove, the horizontality of the worktable plate is ensured, increasing the bending support strength of the worktable plate. This solves the problem of poor compensation effect along the entire length of the workpiece in the prior art, ensuring bending processing accuracy.

Description

Technical Field

[0001] This invention relates to the field of bending processing equipment technology, and more specifically to a deflection compensation device that facilitates the fixing of a worktable. Background Technology

[0002] When a bending machine is loaded, its structure causes the slider to undergo a small, parabolic elastic deformation, resulting in a inconsistent bending angle along the entire length of the workpiece. Furthermore, the bending length of the sheet metal significantly impacts the bending accuracy; longer sheets require greater bending loads, leading to increased machine tilt and slider deformation, making it even more difficult to ensure precision.

[0003] In the prior art, such as the patent "Four-piece Cooperative Wedge Deflection Compensation Device for Bending Machine" with publication number CN101773960A, the application uses four cooperative wedges interacting from top to bottom to compensate for local wear of the die, thereby improving the quality and production efficiency of sheet metal bending. However, when the workpiece is bent along its entire length, the four cooperative wedges require high precision. Locking the wedges for compensation adjustment is inconvenient, and the frequent adjustment of the cooperative wedges causes wear due to the squeezing motion, affecting the compensation accuracy of the worktable. Summary of the Invention

[0004] The purpose of this invention is to provide a deflection compensation device that facilitates fixing the worktable, thereby solving the problem of poor compensation effect along the entire length of bent workpieces in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A deflection compensation device for easy fixation of a worktable, comprising:

[0007] The base and the worktable are provided. The worktable is horizontally arranged above the base and the bottom plate is fixedly connected below it. The base is provided with a compensation adjustment groove along its entire length.

[0008] A deflection compensation mechanism is disposed within the compensation adjustment groove. The deflection compensation mechanism includes a vertical insert plate fixedly connected to the bottom wall of the base. Vertical sliding grooves are symmetrically provided on the inner walls on both sides of the compensation adjustment groove. The vertical sliding grooves are evenly distributed along the entire length of the base, and the vertical insert plate is slidably connected within the vertical sliding groove. The vertical insert plate is engaged with a drive wheel, and the drive wheel is sleeved on a drive shaft. The drive shaft is rotatably mounted on the base.

[0009] A balance locking mechanism is evenly distributed on both sides of the compensation adjustment groove, and the balance locking mechanism is installed on the base, and the relative positions of the base, the worktable and the vertical insert plate are fixed by the balance locking mechanism.

[0019] (2) The controller can automatically compensate for the overall deflection of the bending machine by rotating the locking motor based on the downward movement of the vertical insert plate.

[0029] Please see Figure 1-4As shown, the present invention is a deflection compensation device for facilitating the fixing of a workbench, comprising a base 1, a workbench 2, a deflection compensation mechanism, and a balance locking mechanism. The workbench 2 is horizontally arranged above the base 1, and a base plate 100 is fixedly connected below it. The base 1 has a compensation adjustment groove along its entire length. The deflection compensation mechanism is arranged in the compensation adjustment groove. The vertical insert plate 3 included in the deflection compensation mechanism is fixedly connected to the bottom wall of the base 1. Vertical sliding grooves 4 are symmetrically opened on the inner walls of both sides of the compensation adjustment groove. The vertical sliding grooves 4 are evenly distributed along the entire length of the base 1, and the vertical insert plate 3 is slidably connected in the vertical sliding grooves 4. The vertical insert plate 3 is engaged with and drives a drive wheel 6. The drive wheel 6 is sleeved on a drive shaft 5. The drive shaft 5 is rotatably mounted on the base 1. The balance locking mechanism is evenly distributed on both sides of the compensation adjustment groove and is mounted on the base 1. The balance locking mechanism keeps the relative positions of the base 1, the workbench 2, and the vertical insert plate 3 fixed.

[0030] During the bending process of a workpiece placed on the workbench 2, the workbench 2 is subjected to elastic compression during bending, which causes changes in the deflection of the bending section. This application addresses this issue by setting a deflection compensation mechanism between the workbench 2 and the base 1. The drive shaft 5 drives the drive wheel 6 to rotate, and the angular displacement of the drive wheel 6 changes, causing the vertical insert 3, which is meshed and connected to the drive wheel 6, to adjust its vertical displacement. This satisfies the deflection compensation requirements of the workbench 2. Furthermore, the balance locking mechanism set on both sides of the adjustment compensation groove ensures the levelness of the workbench 2 and increases the bending support strength of the workbench 2. This solves the problem of poor compensation effect along the entire length of the workpiece in the prior art and ensures the bending processing accuracy.

[0031] In this specific embodiment, laser rangefinders 7 are inserted and installed at both ends of the base 1. The laser rangefinders 7 are positioned directly below the vertical insert plate 3. The laser rangefinders 7 are used to monitor the downward movement of the vertical insert plate 3 in real time, so that the obtained downward movement of the worktable 2 deflection is sent to the controller, thereby facilitating the automatic compensation of the downward movement through the deflection compensation mechanism operated by the controller, and realizing the fine adjustment of the compensation value.

[0032] Furthermore, the deflection compensation mechanism also includes a self-locking motor 14. The output end of the self-locking motor 14 is fixedly connected to one end of the drive shaft 5, and an encoder is installed on the self-locking motor 14. The self-locking motor 14 can lock the drive shaft 5 to prevent it from rotating freely along the axial direction. During the deflection compensation adjustment process, the encoder is used to detect the angular displacement of the drive shaft 5, thereby obtaining the rotational angular displacement adjustment of the drive wheel 6 to meet the adjustment of the upward movement of the vertical insert 3. The self-locking motor 14 and the encoder can be connected to the bending machine controller through a line so that the CNC bending machine controller can accurately realize the automatic compensation of the overall deflection of the bending machine by rotating the self-locking motor 14 according to the detected downward movement of the vertical insert 3.

[0033] Furthermore, the vertical insert plate 3 has several teeth 30 evenly distributed on its surface, and the drive wheel 6 has several teeth 60 on its circumferential sidewall. The teeth 30 and teeth 60 are meshed and connected, and both teeth 30 and teeth 60 are made of high-strength alloy steel. During the deflection compensation adjustment process, teeth 30 and teeth 60 mesh and are connected to ensure stable adjustment of the upward movement of the vertical insert plate 3. The vertical insert plate 3 and the drive wheel 6 can be manufactured in a standardized manner to meet the needs of fine-tuning compensation. In addition, the teeth 30 and teeth 60 made of high-strength alloy steel have wear resistance and extend their service life.

[0034] In this specific embodiment, the balance locking mechanism includes a balance guide tube 8 embedded in the base 1. The top end of the balance guide tube 8 is threadedly connected to a T-shaped screw 10. A locking plate 11 is slidably sleeved on the balance guide tube 8. The locking plate 11 is vertically connected to the side wall of the vertical insert plate 3. The worktable plate 2 is clamped and fixed by the screw 10 and the locking plate 11. The worktable plate 2 is horizontally set above the base 1. During installation, it is easy to connect to the balance guide tube 8 by the screw 10. The screw 10 and the locking plate 11 clamp and position the worktable plate 2. When there is a downward displacement due to the bending process of the worktable plate 2, it is easy to drive the vertical insert plate 3 to compensate for the upward displacement through the deflection compensation structure, so that the locking plate 11 can balance and support the worktable plate 2 and ensure the stability of the bending process of the worktable plate 2.

[0035] Furthermore, the outer wall of the balance guide tube 8 is tapped with threads, and a locking block 12 is threadedly connected to the threaded wall of the balance guide tube 8. The locking block 12 supports and abuts against the locking plate 11. During the initial installation of the worktable 2, it is convenient to rotate along the balance guide tube 8 by means of the locking block 12, thereby strengthening the supporting effect of the locking plate 11 on the worktable 2. When the worktable 2 causes a downward displacement due to deflection, the deflection compensation mechanism generates a continuous upward driving force on the vertical insert plate 3 and the worktable 2 to meet the requirements of deflection fine adjustment compensation. The operator periodically rotates the locking block 12 upward to adjust the support of the locking plate 11, ensuring that the screw 10, the locking plate 11 and the locking block 12 are clamped and fixed to the worktable 2, which can avoid the expansion of the deflection adjustment compensation amount.

[0036] Furthermore, the worktable 2 is provided with a guide hole 9 that is connected to the balance guide tube 8. The top end of the balance guide tube 8 is restricted within the guide hole 9, which can ensure that the worktable 2 is balanced in the width direction and can enhance the stability of the vertical deflection compensation of the worktable 2.

[0037] In this specific embodiment, the bottom wall of the worktable 2 is provided with an integrally structured insert 13. The width of the insert 13 is set to be consistent with the width of the compensation adjustment groove. The worktable 2 and the compensation adjustment groove on the base 1 are suspended structures. During the bending process, the worktable 2 is prone to deformation due to compression in the position of the suspended structure. By restricting it within the compensation adjustment groove by the insert 13, the support strength of the worktable 2 in the position of the suspended structure can be strengthened to achieve a better compensation effect.

[0038] The working principle of this invention is as follows: When the worktable 2 experiences a downward displacement due to deflection during bending of the workpiece, a laser rangefinder 7 is used to monitor the downward displacement of the vertical insert 3 in real time. This allows the obtained downward displacement of the worktable 2 to be sent to the controller, which then operates the deflection compensation mechanism to automatically compensate for the downward displacement, achieving fine-tuning of the compensation value. The controller can accurately achieve automatic compensation of the overall deflection of the bending machine by rotating the locking motor 14 based on the detected downward displacement of the vertical insert 3. During the deflection compensation adjustment process, an encoder is used to detect the angular displacement of the drive shaft 5, thereby obtaining the rotational angular displacement adjustment of the drive wheel 6 to meet the upward displacement adjustment of the vertical insert 3, achieving a better compensation effect. After each workpiece bending is completed, the operator periodically rotates the locking block 12 upward to support the locking plate 11, ensuring that the worktable 2 is clamped and fixed between the screw 10, the locking plate 11, and the locking block 12, thus preventing the expansion of the deflection adjustment compensation amount.

[0039] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
