Description

Technical Field

[0001] This utility model belongs to the field of slider guidance for bending machines, specifically a slider guidance adjustable bidirectional guide wheel mechanism. Background Technology

[0002] Electric servo bending machines are highly versatile and suitable for a variety of applications, including precision sheet metal bending, small household appliances, and computer and equipment housings. They are specifically designed for bending metal materials and are ideal for precision sheet metal parts and machined components.

[0003] A search of CN210907496U discloses an upper slider lifting mechanism for a bending machine, comprising two parallel and spaced bending vertical plates, a bending horizontal plate arranged between the two bending vertical plates, an upper slider arranged at one end of the two bending vertical plates, a lifting drive mechanism driven by the upper slider, and two guide modules arranged inside the upper slider; each guide module is arranged at one end of the inner side of the upper slider, and the upper slider is slidably connected to the two bending vertical plates via the two guide modules. In practical applications, this technology suffers from multi-directional off-center displacement of the bending machine slider during bending motion, which can easily cause the second guide vertical plate to float up. This results in stiff slider movement during high-speed operation, leading to abnormal noise from the ball screw and a shortened lifespan. Utility Model Content

[0004] The technical problem to be solved by this utility model is that when the slider of the bending machine is bending, it will be found to be displaced in multiple directions, which will easily cause the second guide plate to float up, resulting in stiff slider movement during high-speed operation, abnormal noise of the ball screw and shortened life.

[0005] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this utility model, which adopts the following technical solution:

[0006] A slider-guided adjustable bidirectional guide wheel mechanism includes:

[0007] Wear-resistant guide plate one, wear-resistant guide plate one is provided with two sets, left and right. Wear-resistant guide plate one is adjustable and installed on the rear side of the slider. The adjustment direction is perpendicular to the rear wall of the slider. The arrangement direction of wear-resistant guide plate one is parallel to the movement direction of the slider.

[0008] Wear-resistant guide plate two, which is provided in two sets, left and right. Wear-resistant guide plate two is installed on the inner wall of the wall panel. The arrangement direction of wear-resistant guide plate two is parallel to the movement direction of the slider.

[0009] Guide wheel assembly one, which is installed on the wall panel and attached to the wear-resistant guide plate one;

[0010] Guide wheel assembly two is installed behind the slider and attached to wear-resistant guide plate two.

[0011] In a preferred embodiment, the wear-resistant guide plate has a mounting hole on its rear side facing forward. A connecting bolt is installed in the mounting hole to connect the slider. An adjusting block is fitted on the outside of the connecting bolt located in the mounting hole. Threaded holes are opened on both sides of the wear-resistant guide plate, and adjusting screws are installed in the threaded holes. The adjusting screws are used to adjust the adjusting block away from the slider.

[0012] In a preferred embodiment, both sides of the adjusting block are provided with pressure-bearing inclined surfaces, which gradually approach the axis of the connecting bolt along the direction close to the slider.

[0013] In a preferred embodiment, both guide wheel group one and guide wheel group two are provided in two sets and are symmetrically distributed from left to right;

[0014] The guide wheel assembly has two rollers distributed on the left and right sides, and the outer circumference of the rollers rolls on the left and right sides of the wear-resistant guide plate.

[0015] The guide wheel assembly has two rollers distributed in the front and back, with the outer circumference of the rollers rolling on the front and back sides of the wear-resistant guide plate.

[0016] In a preferred embodiment, both the top and bottom of the first and second wear-resistant guide plates are provided with sloping surfaces, which are used to install the corresponding guide wheel assemblies.

[0017] In a preferred embodiment, both the first guide wheel assembly and the second guide wheel assembly include a mounting base, and the mounting base is provided with mounting holes;

[0018] The roller includes a wheel body located inside the mounting base, an eccentric bearing installed inside the wheel body, a fixed shaft installed inside the eccentric bearing, a limit washer fitted on one end of the fixed shaft and passing through the corresponding mounting base, and an external thread provided on the outer side of the passing end, the limit washer being located inside the mounting base, and a locking nut matching the external thread for pressing the limit washer against the outer wall of the mounting base.

[0019] In a preferred embodiment, a one-way ratchet is provided between the limiting gasket and the opposite sidewall of the mounting base;

[0020] One end of the fixed shaft is provided with a limiting end located inside the wheel body, and along the direction away from the limiting end, there are socket section, adapter section and external thread section with progressively decreasing size.

[0021] The socket section is inserted into the eccentric bearing, and the cross-section of the fitting section is square and slides axially with the limiting washer without relative rotation.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This utility model achieves vertical movement by clamping wear-resistant guide plates with two sets of rollers (front and rear, left and right). Adjustment blocks are installed in the left and right wear-resistant guide plates to adjust their running direction, ensuring that the wear-resistant guide plates are parallel to the ball screw. The adjustment blocks have an upward slope, which increases the axial locking force when adjusting the screw, preventing the guide plate from floating and causing unevenness on the guide surface. This significantly improves the rigidity of the linear guide, reduces deformation and vibration, and ensures the guide remains stable under external forces. The slider's movement is smoother, and the linear guide wheels greatly reduce the coefficient of friction, thus reducing the resistance received by the ball screw. This allows the slider to move at high speed without damaging the ball screw, improving the slider's working efficiency.

[0024] 2. This utility model achieves roller adjustment by setting the roller with an eccentric adjustable method, and using a locking nut and external thread to press the limiting washer onto the side wall of the mounting base, thereby facilitating installation and making the holding force controllable and adjustable.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Example 1: A slider-guided adjustable bidirectional guide wheel mechanism, comprising:

[0036] Wear-resistant guide plate 10, which is provided in two sets, left and right. Wear-resistant guide plate 10 is adjustable and installed on the rear side of the slider. The adjustment direction is perpendicular to the rear wall of the slider. The arrangement direction of wear-resistant guide plate 10 is parallel to the movement direction of the slider.

[0037] Wear-resistant guide plate 20, there are two sets of wear-resistant guide plates 20, one on the left and one on the right. Wear-resistant guide plates 20 are installed on the inner wall of wall plate 60. The arrangement direction of wear-resistant guide plates 20 is parallel to the direction of slider movement.

[0038] Guide wheel assembly 30 is installed on wall panel 60 and attached to wear-resistant guide plate 10.

[0039] Guide wheel assembly 20 is installed behind slider 50 and attached to wear-resistant guide plate 20.

[0040] When eccentric loading occurs, in traditional structures, the wear-resistant guide plate is fixed to the slider 50, and the distance between them cannot be adjusted. This causes the wear-resistant guide plate and the slider 50 to move together, resulting in clamping between the wear-resistant guide plate and one side pad, increasing the resistance of the other side pad, and making the movement of the slider 50 stiff. Since machining and assembly errors are unavoidable in actual implementation, it is necessary to adjust the parallelism between the wear-resistant guide plate and the ball screw. The solution in this embodiment adjusts the distance between the wear-resistant guide plate 10 and the slider 50, ensuring that the movement direction of the wear-resistant guide plate 10 is always parallel to the vertical movement of the ball screw. This reduces the moving resistance of the slider 50, preventing damage to the ball screw during high-speed movement of the slider, thus improving the working efficiency of the slider.

[0041] Example 2, based on the above examples, makes the following improvements:

[0042] The wear-resistant guide plate 10 has a mounting hole on its rear side facing forward. A connecting bolt 14 is installed in the mounting hole to connect the slider 50. An adjusting block 11 is fitted on the outside of the connecting bolt 14 located in the mounting hole. Threaded holes are provided on both sides of the wear-resistant guide plate 10, and adjusting screws 12 are installed in the threaded holes. The adjusting screws 12 are used to adjust the adjusting block 11 to the side away from the slider 50. Pressure-bearing inclined surfaces 13 are provided on both sides of the adjusting block 11, and the pressure-bearing inclined surfaces 13 gradually approach the axis of the connecting bolt 14 along the direction closer to the slider 50.

[0043] By adjusting the screw 12, the pressure-bearing inclined surfaces 13 on both sides of the adjusting block 11 can be squeezed, so that the wear-resistant guide plate 10 is always in a vertical (parallel lead screw) state during operation, thereby making the movement of the slider 50 smoother.

[0044] Example 2, based on the above examples, makes the following improvements:

[0045] The guide wheel assembly 30 and the guide wheel assembly 40 are each provided in two sets and are symmetrically distributed from left to right.

[0046] The guide wheel assembly 30 is equipped with two rollers distributed on the left and right sides, and the outer circumference of the rollers is rolled on the left and right sides of the wear-resistant guide plate 10.

[0047] The guide wheel assembly 40 is equipped with two rollers distributed in the front and rear, and the outer circumference of the rollers is rolled on the front and rear sides of the wear-resistant guide plate 20.

[0048] To facilitate the installation of the guide wheel assembly, the top and bottom of the wear-resistant guide plate 10 and the wear-resistant guide plate 20 are provided with sloping surfaces, which are used to install the corresponding guide wheel assembly.

[0049] To facilitate roller installation and controllable and adjustable clamping force on the wear-resistant guide plate:

[0050] Therefore, both the first guide wheel assembly 30 and the second guide wheel assembly 40 include a mounting base 70, and the mounting base 70 is provided with mounting holes;

[0051] The roller includes a wheel body 71 located inside the mounting base 70. An eccentric bearing 72 is installed inside the wheel body 71. A fixed shaft 73 is installed inside the eccentric bearing 72. A limiting washer 75 is fitted on one end of the fixed shaft 73 and passes through the corresponding mounting base 70. An external thread 74 is provided on the outer side of the end that passes through. The limiting washer 75 is located inside the mounting base 70. A locking nut 76 is matched on the external thread 74 to press the limiting washer 75 against the outer wall of the mounting base 70.

[0052] A one-way ratchet is provided between the limiting gasket 75 and the opposite sidewalls of the mounting base 70;

[0053] One end of the fixed shaft 73 is provided with a limiting end 731 located inside the wheel body 71, and along the direction away from the limiting end 731, there are socket section 732, adapter section 733 and external thread section with progressively decreasing size.

[0054] The socket section 732 is inserted into the eccentric bearing 72, and the adapter section 733 has a square cross-section and slides axially with the limiting washer 75 without relative rotation.

[0055] The roller is installed in the inner ring of the eccentric bearing 72 by socket section 732, and the limiting washer 75 is fitted in the adapter section 733. The locking nut 76 locks the limiting washer 75 to the side wall of the mounting base 70, thereby completing the roller installation and the controllability and adjustment of the clamping force of the wear-resistant guide plate.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
