Description

Technical Field

[0001] The utility model relates to the technical field of spray painting processing equipment, and particularly relates to an inner side processing device for a bushing. Background Art

[0002] An automotive suspension tie rod is one of the main components of an automobile, and its quality and reliability will directly affect the driving experience of the automobile. As a moving part, the automotive suspension tie rod is prone to wear during long-term friction. When the wear of the connecting end of the tie rod reaches a certain degree, it must be replaced. Therefore, in the prior art, a bushing with better wear resistance is often equipped at the connecting end of the automotive suspension tie rod to protect the connecting end of the automotive suspension tie rod through the bushing.

[0003] The bushing is usually annular and made of wear-resistant material, mainly acting as a gasket for the automotive suspension tie rod. Since the assembly accuracy requirement between the bushing and the automotive suspension tie rod is relatively high, the bushing needs to go through multiple processes such as inspection, oiling, and spray painting after being produced.

[0004] When spray painting the inner peripheral side of the bushing, the working head of the spray gun needs to be inserted into the inner hole of the bushing. Therefore, spray painting is currently mostly carried out manually. However, the quality stability of manual spray painting cannot be guaranteed, and the efficiency is relatively low. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an inner side processing device for a bushing that can automatically spray paint the inner peripheral side of the bushing, with high efficiency and stable quality.

[0006] To solve the above problems, the utility model provides an inner side processing device for a bushing, including:

[0007] A clamping seat for placing the bushing vertically;

[0008] A first lifting driving member, which is arranged adjacent to the clamping seat. The first lifting driving member is provided with a lifting frame that can move vertically. An operating member is arranged on the lifting frame and the operating member is located above the clamping seat. The operating member is provided with a downward operating head for extending into the inner hole of the bushing on the clamping seat;

[0009] A second lifting driving member, which is arranged adjacent to the clamping seat. The second lifting driving member is provided with an inner spray pressing frame that can move vertically. The inner spray pressing frame is located above the clamping seat and is used to press against the bushing on the clamping seat under the drive of the second lifting driving member.

[0010] In the above solution, the inner spray pressure frame is first driven to lift and lower by the second lifting drive. After the inner spray pressure frame descends and presses against the bushing of the clamping seat, the bushing is effectively fixed relative to the clamping seat. Subsequently, the first lifting drive drives the working member to descend so that the working head of the working member extends into the inner hole of the bushing, and then the corresponding processing operation can be realized. The specific type of the working member can be changed according to needs. For example, in this solution, the working member is a paint spray gun, and the working head is a nozzle with a 360° spray range. Compared with the prior art where painting is carried out manually, the above solution does not require manual participation throughout the process, not only effectively improving the painting efficiency, but also ensuring stable painting quality.

[0011] In an improved solution, the inner spray pressure frame is a plate-like structure extending horizontally. The inner spray pressure frame is provided with a through hole vertically for the working head of the working member to pass through, thus avoiding the interference problem between the inner spray pressure frame and the working head of the working member.

[0012] In an improved solution, the first lifting drive includes a first linear guide rail and a first linear motor arranged vertically. The lifting frame is slidably connected to the first linear guide rail, and the output end of the first linear motor acts on the lifting frame to drive the lifting frame to slide along the first linear guide rail, thereby ensuring the stable and reliable driving effect of the first lifting drive on the lifting frame.

[0013] In an improved solution, the second lifting drive includes a second linear guide rail and a second linear motor arranged vertically. The inner spray pressure frame is slidably connected to the second linear guide rail, and the output end of the second linear motor acts on the lifting frame to drive the lifting frame to slide along the second linear guide rail, thereby ensuring the stable and reliable driving effect of the second lifting drive on the inner spray pressure frame.

[0014] In an improved solution, the first lifting drive and the second lifting drive are respectively located on both sides of the clamping seat, so that the layout is more reasonable.

[0015] In an improved solution, the clamping seat includes a positioning post, a shelf, a bottom plate, a guide post and a spring. The shelf is fixedly arranged and suspended below. The shelf is provided with a guide hole and a positioning hole that both penetrate vertically. The middle part of the guide post is slidably inserted into the guide hole, and the middle part of the positioning post is slidably inserted into the positioning hole. The upper ends of the guide post and the positioning post both extend above the shelf. The upper end of the positioning post is used for inserting into the inner hole of the bushing. A limiting part is arranged at the upper end of the guide post. The spring is located above the shelf and sleeved on the guide post. The upper end of the spring abuts against the limiting part of the guide post and the lower end abuts against the shelf. The lower ends of the guide post and the positioning post both extend below the shelf, and the lower ends of the guide post and the positioning post are connected by the bottom plate. The positioning post is used to keep the bushing in a vertically axis state. In the initial state, the spring applies an upward thrust to the guide post, so that the upper ends of the guide post and the positioning post both remain above the shelf. When a downward pressure is applied to the guide post, the guide post descends and drives the positioning post to descend through the bottom plate, so that the upper end of the positioning post can be disengaged downward from the corresponding inner hole of the bushing, facilitating the operation of the working head of the working piece on the inner hole of the bushing.

[0016] In an improved solution, it further includes a third lifting drive member arranged adjacent to the clamping seat. The third lifting drive member is provided with an adjustable lifting frame that can move vertically. The adjustable lifting frame is located above the guide post of the clamping seat and is used to press against the guide post when driven by the third lifting drive member. Thus, when the third lifting drive member drives the adjustable lifting frame to press down on the guide post, the guide post and the positioning post move downward synchronously, and the upper end of the positioning post can automatically disengage downward from the corresponding inner hole of the bushing.

[0017] In an improved solution, the third lifting drive member is a fixedly arranged cylinder with the cylinder rod facing upward, and the adjustable lifting frame is connected to the cylinder rod of the third lifting drive member, thus ensuring stable and reliable driving of the adjustable lifting frame by the third lifting drive member.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figures 1 - 4 , a bushing inner side processing device provided by an embodiment of the present utility model includes:

[0030] A clamping seat b1 for placing the bushing vertically;

[0031] The first lifting drive member f1 is disposed adjacent to the clamping seat b1. The first lifting drive member f1 is provided with a lifting frame f10 that can move vertically. A working member f2 is provided on the lifting frame f10, and the working member f2 is located above the clamping seat b1. The working member f2 is provided with a working head that extends downward and is used to extend into the inner hole of the bushing on the clamping seat b1;

The inner spraying and pressing frame f4 is located above the clamping seat b1 and is used to press against the bushing on the clamping seat b1 under the drive of the second lifting drive member f3.

[0033] In the above solution, first, the second lifting drive member f3 drives the inner spraying and pressing frame f4 to lift and lower. When the inner spraying and pressing frame f4 descends and presses against the bushing of the clamping seat b1, the bushing is effectively fixed relative to the clamping seat b1. Subsequently, the first lifting drive member f1 drives the working member f2 to descend so that the working head of the working member f2 extends into the inner hole of the bushing, and then the processing operation can be carried out; the specific type of the working member f2 can be changed according to needs. For example, in this embodiment, the working member f2 is a paint spray gun, and the working head is a nozzle with a 360° spraying range, so that the inner hole of the bushing can be automatically painted without manual participation, which not only effectively improves the painting efficiency, but also the painting quality is stable.

[0034] In this embodiment, the inner spraying and pressing frame f4 is a plate-like structure extending horizontally. The inner spraying and pressing frame f4 is provided with a through hole vertically for the working head of the working member f2 to pass through, so as to avoid the interference problem between the inner spraying and pressing frame f4 and the working head of the working member f2.

[0035] In this embodiment, the first lifting drive member f1 includes a first linear guide rail f11 and a first linear motor f12 arranged vertically. The lifting frame f10 is slidably connected to the first linear guide rail f11. The output end of the first linear motor f12 acts on the lifting frame f10 to drive the lifting frame f10 to slide along the first linear guide rail f11, so as to ensure that the driving effect of the first lifting drive member f1 on the lifting frame f10 is stable and reliable.

[0036] In this embodiment, the second lifting drive member f3 includes a second linear guide rail f31 and a second linear motor f32 arranged vertically. The inner spraying and pressing frame f4 is slidably connected to the second linear guide rail f31. The output end of the second linear motor f32 acts on the lifting frame f10 to drive the lifting frame f10 to slide along the second linear guide rail f31, so as to ensure that the driving effect of the second lifting drive member f3 on the inner spraying and pressing frame f4 is stable and reliable.

[0037] In this embodiment, the first lifting drive member f1 and the second lifting drive member f3 are respectively located on both sides of the clamping seat b1, so that the layout is more reasonable.

[0038] AsFigure 3 and Figure 4 as shown ( Figure 3 and Figure 4 there are two positioning posts b11. The left positioning post b11 is equipped with a bushing, and the right positioning post b11 is not equipped with a bushing). In this embodiment, the clamp seat b1 includes a positioning post b11, a shelf b12, a bottom plate b13, a guide post b14, and a spring b15. The shelf b12 is fixedly arranged and suspended below. The shelf b12 is provided with a guide hole b122 and a positioning hole b121 that both penetrate vertically. The middle part of the guide post b14 is slidably inserted into the guide hole b122, and the middle part of the positioning post b11 is slidably inserted into the positioning hole b121. The upper ends of the guide post b14 and the positioning post b11 both extend above the shelf b12. The upper end of the positioning post b11 is used to be inserted into the inner hole of the bushing. The upper end of the guide post b14 is provided with a limiting portion b141. The spring b15 is located above the shelf b12 and sleeved on the guide post b14. The upper end of the spring b15 abuts against the limiting portion b141 of the guide post b14 and the lower end abuts against the shelf b12. The lower ends of the guide post b14 and the positioning post b11 both extend below the shelf b12, and the lower ends of the guide post b14 and the positioning post b11 are connected by the bottom plate b13. The upper end of the positioning post b11 is used to keep the bushing in a state where the axis is vertical. In the initial state, the spring b15 applies an upward thrust to the guide post b14, so that the upper ends of the guide post b14 and the positioning post b11 both remain above the shelf b12; when a downward pressure is applied to the guide post b14, the guide post b14 descends and drives the positioning post b11 to descend through the bottom plate b13, so that the upper end of the positioning post b11 can be automatically withdrawn downward from the corresponding inner hole of the bushing, facilitating the operation of the working head of the workpiece f2 on the inner hole of the bushing.

[0039] In this embodiment, it further includes a third lifting drive member f5 arranged adjacent to the clamp seat b1. The third lifting drive member f5 is provided with an adjustable lifting frame f6 that can move vertically. The adjustable lifting frame f6 is located above the guide post b14 of the clamp seat b1 and is used to press against the guide post b14 under the drive of the third lifting drive member f5. Thus, when the third lifting drive member f5 drives the adjustable lifting frame to press down on the guide post b14, the guide post b14 and the positioning post b11 move downward synchronously, and the upper end of the positioning post b11 can automatically withdraw downward from the corresponding inner hole of the bushing.

[0040] In this embodiment, the third lifting drive member f5 is a fixedly arranged cylinder and the cylinder rod of the cylinder is arranged upward. The adjustable lifting frame f6 is connected to the cylinder rod of the third lifting drive member f5, thereby ensuring the stable and reliable drive of the third lifting drive member f5 on the adjustable lifting frame f6.
