Description

Technical Field

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

[0002] An automobile 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 automobile 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 automobile suspension tie rod to protect the connecting end of the automobile suspension tie rod through the bushing.

[0003] The bushing is usually annular and made of wear-resistant material, and mainly plays a cushioning role for the automobile suspension tie rod. Since the assembly accuracy requirement between the bushing and the automobile 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 outer peripheral side of the bushing, the spray gun usually needs to go around the bushing for one week, so at present, spray painting is 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 a spray painting device for the outer side of a bushing, which can automatically spray paint the outer peripheral side of the bushing, with high efficiency and stable quality.

[0006] To solve the above problems, the utility model provides a spray painting device for the outer side of a bushing, including:

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

[0008] An outer spray gun arranged on one side of the clamping seat;

[0009] A lifting driving member arranged on the other side of the clamping seat. The lifting driving member is provided with a lifting frame that can move vertically. A rotation motor is arranged on the lifting frame. The output end of the rotation motor is connected with a spray painting clamping claw, and the spray painting clamping claw is located above the clamping seat. The rotation motor is used to drive the spray painting clamping claw to rotate around the vertical axis. The lower part of the spray painting clamping claw is provided with two claw parts that can be opened and closed horizontally, and the claw parts are used to insert into the inner hole of the bushing on the clamping seat.

[0010] Compared with the prior art, in the above solution, a rotation motor is arranged on the lifting frame, and a painting gripper is connected to the output end of the rotation motor. When the clamping seat moves below the painting gripper, the painting gripper moves downward driven by the lifting frame, so that the two claw parts are inserted into the inner hole of the bushing on the clamping seat and then open to realize the clamping of the bushing. Subsequently, the lifting frame drives the painting gripper and the bushing to move upward, and the rotation motor drives the painting gripper and the bushing to rotate. The external paint gun can spray paint on the outer peripheral side of the bushing. The whole process does not require manual participation, which not only effectively improves the painting efficiency, but also has stable painting quality.

[0011] In an improved solution, the lifting driving member includes a linear guide rail and a linear motor both arranged vertically. The lifting frame is slidably connected to the linear guide rail, and the output end of the linear motor acts on the lifting frame to drive the lifting frame to slide along the linear guide rail, so as to ensure the stable and reliable driving effect of the lifting driving member on the lifting frame.

[0012] In an improved solution, the output end of the rotation motor is connected to the upper part of the painting gripper through a vertical transmission shaft, so as to transmit the rotational power of the rotation motor to the painting gripper through the transmission shaft.

[0013] In an improved solution, both the transmission shaft and the painting gripper are two, and a synchronous belt connecting to the two transmission shafts is arranged at the output end of the rotation motor, so that the rotation motor can drive the two painting grippers to rotate around the vertical axis at the same time, that is, the painting operation of two bushings is realized at one time, further improving the efficiency.

[0014] In an improved solution, the opposite sides of the two claw parts are arc-shaped surfaces. The opposite sides of the two claw parts being arc-shaped surfaces can better fit the inner hole of the bushing, realize a more stable clamping effect of the painting gripper on the bushing, and avoid damaging the inner hole of the bushing.

[0015] In an improved solution, the clamping seat is provided with an upward protruding positioning post, and the positioning post is used for inserting into the inner hole of the bushing to ensure that the bushing can maintain a vertically axis state on the clamping seat, so as to facilitate the clamping of the painting gripper.

[0016] In an improved solution, a protective cover is further included at the side position of the painting gripper. An opening for the clamping seat to enter is provided on the side wall of the protective cover, so as to realize the shielding protection during painting through the protective cover.

[0026] The present application will be further described in detail below with reference to the drawings and specific embodiments.

[0027] Please refer to Figures 1 - 3 , an outer spray painting device for a bushing provided by an embodiment of the present utility model includes:

[0028] A clamping seat b1 for placing the bushing vertically;

[0029] An outer spray gun e1 disposed on one side of the clamping seat b1;

[0030] The lifting drive member e2 is arranged on the other side of the clamping seat b1. The lifting drive member e2 is provided with a lifting frame e20 that can move vertically. A self-rotating motor e3 is arranged on the lifting frame e20. The output end of the self-rotating motor e3 is connected to a painting gripper e4, and the painting gripper e4 is located above the clamping seat b1. The self-rotating motor e3 is used to drive the painting gripper e4 to rotate with the vertical axis as the axis. Two claw parts e41 that can open and close horizontally are arranged at the lower part of the painting gripper e4, and the claw parts e41 are used to insert into the inner hole of the bushing on the clamping seat b1.

[0031] In the above solution, by arranging the self-rotating motor e3 on the lifting frame e20 and connecting the painting gripper e4 to the output end of the self-rotating motor e3, when the clamping seat b1 moves below the painting gripper e4, the painting gripper e4 moves downward driven by the lifting frame e20, so that the two claw parts e41 open after being inserted into the inner hole of the bushing on the clamping seat b1, realizing the clamping of the bushing; then the lifting frame e20 drives the painting gripper e4 and the bushing to move upward, and the self-rotating motor e3 drives the painting gripper e4 and the bushing to rotate, and the external paint gun e1 can spray paint on the outer peripheral side of the bushing. The whole process does not require manual participation, which not only effectively improves the painting efficiency, but also the painting quality is stable. In addition, the above "clamping seat b1, for placing the bushing vertically" means that when the bushing is placed on the clamping seat b1, the axis of the bushing is vertical.

[0032] In this embodiment, the lifting drive member e2 includes a linear guide rail e22 and a linear motor e21 both arranged vertically. The lifting frame e20 is slidably connected to the linear guide rail e22, and the output end of the linear motor e21 acts on the lifting frame e20 to drive the lifting frame e20 to slide along the linear guide rail e22, so as to ensure the stable and reliable driving effect of the lifting drive member e2 on the lifting frame e20.

[0033] It should be understood that the lifting drive member e2 can also be other forms in the prior art, such as a vertical cylinder, an oil cylinder, etc., as long as it can drive the lifting frame e20 to move vertically, and the specific form is not limited.

[0034] In this embodiment, the output end of the self-rotating motor e3 is connected to the upper part of the painting gripper e4 through a vertical transmission shaft e31, and the transmission shaft e31 is rotatably connected to the lifting frame e20 through a bearing, so as to transmit the rotational power of the self-rotating motor e3 to the painting gripper e4 through the transmission shaft e31.

[0035] Furthermore, both the transmission shaft e31 and the painting gripper e4 are two. The two transmission shafts e31 are arranged in parallel. A synchronous belt e32 is arranged at the output end of the self-rotating motor e3, and the synchronous belt e32 is respectively wound around the upper ends of the two transmission shafts e31, so that the self-rotating motor e3 can drive the two painting grippers e4 to rotate with the vertical axis as the axis at the same time, that is, realizing the painting operation of two bushings at one time and further improving the efficiency.

[0036] As an optimization of the spray painting gripper e4, the opposite sides of the two claw parts e41 are arc-shaped surfaces. The arc-shaped surfaces on the opposite sides of the two claw parts e41 can better fit the inner hole of the bushing, enabling the spray painting gripper e4 to have a more stable clamping effect on the bushing and avoiding damage to the inner hole of the bushing.

[0037] Such as Figure 3 shown, in this embodiment, the clamping seat b1 is provided with an upwardly protruding positioning post b11. The positioning post b11 is used to be inserted into the inner hole of the bushing to ensure that the bushing can maintain a state with a vertical axis on the clamping seat b1, so as to facilitate the clamping of the spray painting gripper e4.

[0038] In this embodiment, it further includes a protective cover e5 located on the side of the spray painting gripper e4. An opening e51 for the clamping seat b1 to enter is provided on the side wall of the protective cover e5, so as to achieve shielding protection during spray painting through the protective cover e5. Figure 3 There are two positioning posts b11 on the middle clamping seat b1. The left positioning post b11 is installed with a bushing, and the right positioning post b11 is not installed with a bushing.
