Description

Technical Field

[0001] This utility model relates to the technical field of automotive stabilizer bar processing equipment, specifically an automotive stabilizer bar drilling device. Background Technology

[0002] A stabilizer bar, also known as an anti-roll bar or balance bar, is an important safety component in a car's suspension system. Its main function is to reduce body roll when the vehicle is cornering or driving on bumpy roads, thereby improving the vehicle's handling stability and driving safety. Stabilizer bars are usually made of spring steel and are U-shaped or V-shaped, with both ends connected to the suspension system via linkages. When the vehicle rolls, the stabilizer bar generates a torsional moment to resist the tilt of the body, thus maintaining the vehicle's balance.

[0003] In the traditional process of drilling holes in automotive stabilizer bars, it is usually necessary to manually flip the stabilizer bar to complete the drilling work at both ends. This operation method is not only inefficient, but also increases the labor intensity of operators, which is not conducive to large-scale production. In addition, manual flipping requires manually aligning the drilling position, which is quite cumbersome.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a drilling device for automotive stabilizer bars to solve the problems mentioned in the background art.

A horizontal pressure plate is fixed at the end of the top rod away from the housing. Vertically positioned limiting plates slide at both ends of the pressure plate along its length. A groove is opened on the side wall of the limiting plate corresponding to the pressure plate. The pressure plate slides in the groove. A return spring is fixed at the bottom of the end of the pressure plate in the groove. The end of the return spring away from the pressure plate is fixed on the inner wall of the bottom of the groove. The distance between the two top plates is greater than the sum of the cross-sectional diameter of the fixed block and the length of the extension. Two extensions with the same structure are fixed on the outer arc wall of the fixed block. The included angle between the two extensions is an obtuse angle. In the initial state, one extension is set vertically upward, and the other extension is parallel to one of the inclined surfaces at the top of the guide block.

[0010] Furthermore, the top and bottom of the side wall away from the pivot of the housing are provided with horizontally arranged sliding channels one, and the side wall along the length of the housing is provided with vertically arranged sliding channels two. Both sliding channels one and sliding channels two penetrate the side wall of the housing and are connected to the interior of the housing. A pull rod slides in sliding channel two. A fixing frame is fixed to the end of the pull rod near the interior of the housing. Sliding columns are fixed at the four corners of the side wall away from the pivot of the fixing frame. The axis of the sliding columns is perpendicular to the surface of the fixing frame. A guide plate slides at the end of the sliding column away from the fixing frame. An inclined sliding groove is provided on the side wall of the guide plate near the fixing frame. The sliding column slides in the inclined sliding groove. The inclined sliding grooves on the two guide plates located on the same horizontal plane are symmetrically arranged.

[0011] Furthermore, a limiting block is fixed to one end of the guide plate away from the fixed frame. The limiting block slides within the sliding channel. A fixed plate is fixed to one end of the limiting block away from the guide plate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see the appendix Figure 1 To be continued Figure 4 The present invention provides a drilling device for a car stabilizer bar: including a drilling device 10, a support block 1 20 and a support block 23. A fixed frame 21 is slidably mounted on the top of the support block 1 20. A guide block 211 is fixed at the center of the top of the fixed frame 21. A horizontally arranged top plate 22 is fixed on one side wall of the top two ends of the fixed frame 21 that are close to each other. An inclined surface is provided on the top of the guide block 211 at one end close to the two top plates 22 respectively.

[0027] A slider 24 slides vertically on one side wall of support block 23. A horizontal rotating shaft 28 passes through the center of one side wall of support block 23 along the length direction of support block 23. A fixing block 27 is fixed to one end of the outer arc wall of the rotating shaft 28 near support block 1 20. The other end passes through slider 24 and is fixed with rotating plate 25. The end of the rotating shaft 28 near support block 1 20 passes through fixing frame 21 and is fixed with housing 30. A clamping mechanism is provided inside housing 30.

[0028] An extension portion one extending radially is fixed on the outer arc wall of the fixed block 27. A fixed post is fixed on the side wall of the extension portion one away from the fixed block 27, close to the support block 20. The fixed post slides against the inclined surface of the guide block 211. An extension portion two extending radially is fixed on the outer arc wall of the rotating plate 25. A tension spring 26 is installed on the end of the extension portion two away from the rotating plate 25. A vertically arranged extension portion three is connected to the end of the tension spring 26 away from the extension portion two. The extension portion three is fixed to the bottom of the slider 24.

[0029] An electric slide table is embedded in the slider 24. The slider 24 is installed on the electric slide table. A top rod 31 is fixed at the top and bottom of the housing 30. A horizontal pressure plate 12 is fixed at the end of the top rod 31 away from the housing 30. Vertically arranged limiting plates 11 slide at both ends of the pressure plate 12 along its own length direction. A sliding groove is opened on the side wall of the limiting plate 11 corresponding to the pressure plate 12. The pressure plate 12 slides in the sliding groove. A return spring is fixed at the bottom of the end of the pressure plate 12 located in the sliding groove. The end of the return spring away from the pressure plate 12 is fixed on the bottom inner wall of the sliding groove.

[0030] The distance between the two top plates 22 is greater than the sum of the cross-sectional diameter of the fixing block 27 and the length of the extension 1. Two extensions 1 with the same structure are fixed on the outer arc wall of the fixing block 27. The included angle between the two extensions 1 is an obtuse angle. In the initial state, one of the extensions 1 is set vertically upward, and the other extension 1 is parallel to one of the inclined surfaces at the top of the guide block 211.

[0031] The top and bottom of the side wall of the housing 30 away from the rotating shaft 28 are provided with a horizontal sliding channel 1, and the side wall of the housing 30 along its own length is provided with a vertical sliding channel 2. Both the sliding channel 1 and the sliding channel 2 pass through the side wall of the housing 30 and are connected to the interior of the housing 30. A pull rod 37 slides in the sliding channel 2.

[0032] It should be noted that: the length direction of support block 20 is consistent with the length direction of fixed frame 21, the length direction of slider 24 is perpendicular to the length direction of support block 20, and the length direction of slider 24 is parallel to the axis of rotating shaft 28. The vertical cross-section of fixed frame 21 along its own length direction is "door" shaped and the opening is set away from support block 20. Top plate 22 is horizontally fixed to the inner side of the end of fixed frame 21.

[0033] Limiting posts are fixed at both ends of the slider 24 on the side wall away from the fixed block 27, located outside the rotating plate 25 in the horizontal direction. When the extension part 2 is in the horizontal state, the limiting posts abut against the side wall of the extension part 2 at the bottom.

[0034] Support block 1 20 provides support for the fixed frame 21, support block 23 and slider 24 provide support for the flipping mechanism. In the initial state, one of the fixed posts abuts against the inclined surface of the guide block 211, the rotating plate 25 is in a horizontal state and the extension 2 abuts against one of the limiting posts, the length direction of the slider 24 is perpendicular to the length direction of support block 1 20, the rotating plate 25 is located on the side of the slider 24 away from support block 1 20, there are two extensions on the outer arc wall of the fixed block 27, and the length direction of the two extensions 1 is consistent with the radial direction of the fixed block 27, the included angle of the two extensions 1 is an obtuse angle, and the extension 3 is vertically arranged at the bottom of the slider 24.

[0035] When the slider 24 rises, another fixed column will abut against the top plate 22 on the corresponding side. At this time, the top plate 22 is mainly subjected to the force from the vertical direction. Therefore, the fixed frame 21 will not slide relative to the support block 20 due to the push of the fixed column. At this time, the fixed block 27 will rotate around the fixed column that abuts against the top plate 22. At this time, the fixed column drives the fixed block 27 to rotate in the opposite direction. The fixed column on the other side will pass between the two top plates 22.

[0036] The fixed block 27 drives the rotating shaft 28 to rotate, and the rotating shaft 28 drives the rotating plate 25 to rotate. When the rotating plate 25 rotates more than 90 degrees, it overcomes the elastic force of the tension spring 26. The rotating plate 25 will drive the extension part 2 on it to rotate to the other side and abut against the limit post on the other side. At this time, the tension spring 26 is in a stretched state and has a tendency to contract, thus ensuring that it will not reverse. When the slider 24 descends, the fixed post at the bottom will first abut against the inclined surface of the guide block 211, thus forcing the fixed block 27 to slide, thus ensuring that the fixed post that does not abut against the top plate 22 can pass between the two top plates 22 when it rises again.

[0037] When the slider 24 slides vertically, it will also drive the housing 30 and the push rod 31 on it to move. When the slider 24 descends, the limiting plate 11 will first contact the support plane of the worktable, and then the pressure plate 12 will slide relative to the limiting plate 11. When the end of the clamped stabilizing rod abuts against the support plane of the worktable, the pressure plate 12 will be pushed down by the push rod 31 to press down the stabilizing rod, forming further fixation.

[0038] Please see the appendix Figure 1 To be continued Figure 4 The present invention provides a technical solution: a fixed frame is fixed at one end of the pull rod 37 near the inside of the housing 30, and sliding columns 32 are fixed at the four corners of the side wall of the fixed frame away from the rotating shaft 28. The sliding columns 32 are axially perpendicular to the surface of the fixed frame. A guide plate 33 slides on the end of the sliding column 32 away from the fixed frame. An inclined sliding groove is opened on the side wall of the guide plate 33 near the fixed frame. The sliding column 32 slides in the inclined sliding groove. The inclined sliding grooves on the two guide plates 33 located in the same horizontal plane are symmetrically arranged.

[0039] A limiting block is fixed to one end of the guide plate 33 away from the fixed frame. The limiting block slides in the sliding channel. A fixing plate 34 is fixed to one end of the limiting block away from the guide plate 33. A clamping mechanism is provided on the side wall of the two fixing plates 34 located on the same horizontal plane that are close to each other.

[0040] A clamping plate 35 is slidably mounted on one of the fixed plates 34 near the middle of the housing 30 along the width direction of the housing 30, and a clamping plate 36 is fixed on the other fixed plate 34 near the middle of the housing 30 along the width direction of the housing 30.

[0041] A horizontally arranged sliding groove is provided on the fixed plate 34 on which the first clamping plate 35 slides. Two clamping plates 35 slide in the sliding groove. The same reset spring is fixed on the side wall of the two clamping plates 35 that are close to each other. Two clamping plates 36 are fixed on the other fixed plate 34 along the width direction of the housing 30. The ends of the two clamping plates 36 that are away from the corresponding fixed plate 34 are arranged away from each other.

[0042] It should be noted that: when the lever 37 is pulled manually, the fixed frame slides vertically, and the fixed frame moves the sliding column 32. Since the sliding column 32 slides in the inclined groove of the guide plate 33, the guide plates 33 on the same horizontal plane are forced to move closer together. Conversely, the guide plates 33 on the same horizontal plane can be moved further apart.

[0043] Furthermore, the ends of clamp 35 and clamp 36 that are close to each other are both inclined surfaces with complementary inclination angles. When clamp 35 and clamp 36 approach each other, the inclined surface at the end of clamp 35 slides and abuts against the inclined surface at the end of clamp 36. Since the end of clamp 36 that is away from its corresponding fixed plate 34 is extended outward, clamp 35 will be forced to close after contacting it. At this time, the reset spring stores force and then clamps the stabilizer bar. During reset, the reset spring drives the two clamps 35 on the same fixed plate 34 to move away from each other.

[0044] Working principle:

[0045] During operation, the slider 24 slides vertically along the support block 23, which drives the rotating shaft 28 and the housing 30 to move and adjust the drilling depth. The fixing post on the fixing block 27 slides against the inclined surface of the guide block 211, driving the rotating shaft 28 to rotate and realize the flipping of the stabilizer bar. The tension spring 26 on the rotating plate 25 provides the restoring force to ensure that the stabilizer bar is in an accurate position after flipping.

[0046] The clamping mechanism inside the housing 30 pulls the fixed frame through the pull rod 37, causing the sliding column 32 to slide in the inclined groove of the guide plate 33, forcing the guide plate 33 and the fixed plate 34 to move horizontally, so that the clamping plate 1 35 and the clamping plate 2 36 clamp or release the stabilizing rod. The pressure plate 12 moves down with the housing 30 and presses down the stabilizing rod through the limiting plate 11 to prevent the drilling from deviating. After the drilling is completed, the slider 24 rises, the fixed column abuts against the top plate 22, and the fixed block 27 rotates to prepare for the next drilling.
