Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to a contour positioning and hoisting device for electrophoretic spare parts frames in a coating workshop. Background Technology

[0002] Currently, the production process for electrophoretic spare parts in the painting workshop is as follows: 1. Welding Hanging: The spare part frame to be electrophoretically coated is hung from the welding skid onto the pre-painting treatment hanger and locked. 2. Pre-treatment Electrophoresis: The pre-treatment and electrophoresis processes are completed. 3. Painting Hanging: The spare part frame is hung from the painting hanger onto the intermediate skid. 4. Lift Transfer: The spare part frame is lowered onto the painting skid via a lift. 5. Drying Process: After the spare part frame is transported to the drying oven and the baking process is completed, the electrophoretically baked parts are removed. 6. Empty Spare Part Frame Return: The empty spare part frame is transferred from the painting hanging area to the intermediate skid, then hung onto the painting hanger and locked. 7. Spare Part Frame Installation: The empty spare part frame is returned to the welding area, ready for the spare part to be installed again.

[0003] The following are the core defects in the current hoisting of electrophoretic spare parts frames in the painting workshop: 1. Structural incompatibility: The spare parts frame cannot be directly matched with the painting hanger and needs to be transferred through the welding mounting area. The existing spare parts frame needs to be installed on the pre-treatment hanger through the welding mounting area, which causes a conflict with the welding vehicle body path (reverse transport). The welding vehicle needs to wait for two workstations, with a single downtime loss of 300 seconds per batch and a downtime loss of 190,000 yuan per year.

[0004] 2. Low positioning accuracy: The fixed opening of the pre-treatment hanger legs cannot accommodate the width difference (±10cm) between the parts frame and the vehicle body. During painting, the intermediate skid transfer requires multiple positioning operations, taking 180 seconds. When the position error exceeds ±2cm, it adds extra downtime and easily causes the risk of electrophoretic solution back-dissolving, with a back-dissolving probability of up to 8%, significantly increasing energy consumption and maintenance costs. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a contour positioning and hoisting device and system for electrophoretic spare parts frames in painting workshops, which can achieve: the spare parts frames can be directly hung on the painting hoist, eliminating the welding transfer link; accurately matching spare parts frames of different widths, and extending compatibility to multiple vehicle models.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: This utility model provides a contour positioning and hoisting device for electrophoretic spare parts frames in a painting workshop, comprising: The painting hoist includes a hoisting frame and a front and rear hoisting feet that are laterally connected to the bottom of the hoisting frame. The rotation angle of the front and rear hoisting feet on the horizontal plane is adjustable. The front positioning hole assembly is located at the head of the spare parts frame base and is used to mate with the front support pin located at the top of the front suspension foot. The rear support assembly is located at the rear of the spare parts frame base and is used to dock with the rear support structure located at the top of the rear suspension foot.

[0007] As a further optimization of this utility model, the front positioning hole assembly includes: First upper baffle; The first lower baffle is located below the first upper baffle and is detachably connected to it; A positioning cylinder is fixed to the bottom of the first lower baffle, and the bottom of the positioning cylinder has a positioning hole that engages with the front support pin.

[0008] As a further optimization of this utility model, the first upper baffle is located on the upper surface of the spare parts frame base, the first lower baffle is located on the lower surface of the spare parts frame base, and the first upper baffle and the first lower baffle are fixed together by connecting bolts; the front support pin is located below the positioning cylinder.

[0009] As a further optimization of this utility model, the diameter of the positioning hole is 20±0.1mm.

[0010] As a further optimization of this utility model, the rear fulcrum component includes: Second upper baffle; The second lower baffle is located below the second upper baffle and is detachably connected to it; A support member is fixed to the bottom of the second lower baffle, and the side wall of the support member has an elongated hole that can be inserted and matched with the rear support structure.

[0011] As a further optimization of this utility model, the rear support structure includes a support leg, a U-shaped bracket, and an F-shaped pin. The support leg is fixed to the top of the rear suspension foot, the base plate of the U-shaped bracket is fixed to the top of the support leg, and through holes are provided on both side plates of the U-shaped bracket. The support member is located between the two side plates, and a limiting baffle is provided on the outside of one side plate of the U-shaped bracket. The F-shaped pin is inserted into the through hole and the elongated hole to form a limiting relationship with the limiting baffle.

[0012] As a further optimization of this utility model, the second upper baffle is located on the upper surface of the spare parts frame base, the second lower baffle is located on the lower surface of the spare parts frame base, and the second upper baffle and the second lower baffle are fixed together by connecting bolts.

[0013] As a further optimization of this utility model, both the front and rear suspension feet are connected to the bottom of the hoisting frame through a multi-mode limiting structure. The multi-mode limiting structure includes a connecting frame, a limiting plate, and a slot. One side of the connecting frame is fixedly connected to the front or rear suspension foot, and the other side is located at the bottom of the hoisting frame and rotatably connected thereto. Multiple slots are provided at intervals along the rotation direction on the outer edge of the top of the connecting frame on the side opposite to the front or rear suspension foot. One end of the limiting plate is rotatably connected to the hoisting frame above the connecting frame, and the other end is inserted into the slot for limiting engagement.

In terms of compatibility, it can adapt to various spare parts frames of different sizes. By changing the rear support module and adjusting the installation position of the front positioning hole module, it can be compatible with multiple vehicle models. In terms of energy consumption and cost control, due to the elimination of intermediate skid transfer and remelting risks, the energy consumption per frame is reduced from 95.04 yuan to 31.68 yuan, which can save 76,000 yuan in costs when the annual production capacity is 1200 frames. In terms of quality stability, the contour positioning design controls the spare parts frame lifting offset within ±1mm, reduces the remelting rate from 8% to 0, and increases the product qualification rate to 99%.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting the present utility model. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. For those skilled in the art, the omission of certain well-known structures and their descriptions in the drawings is understandable. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting the present utility model.

[0025] like Figures 1-6 As shown, this utility model embodiment provides a contour positioning and hoisting device for electrophoretic spare parts frames in a painting workshop, including a painting hoist 1, a front positioning hole assembly 2, and a rear support assembly 3.

[0026] In some embodiments, the painting hanger 1 includes a lifting frame 101, front lifting feet 102, and rear lifting feet 103. Two front lifting feet 102 are symmetrically arranged laterally on both sides of the bottom front end of the lifting frame 101, and two rear lifting feet 103 are symmetrically arranged laterally on both sides of the bottom rear end of the lifting frame 101. The rotation angle of the front lifting feet 102 and rear lifting feet 103 on the horizontal plane is adjustable. This adjustable rotation angle design provides a basis for adapting to spare parts frames and vehicle bodies of different widths, helping to improve the compatibility of the device.

[0027] Specifically, both the front hanger 102 and the rear hanger 103 are connected to the bottom of the lifting frame 101 via a multi-mode limiting structure 5. The multi-mode limiting structure 5 includes a connecting frame 501, a limiting plate 502, and slots. One side of the connecting frame 501 is fixedly connected to either the front hanger 102 or the rear hanger 103, while the other side is located at the bottom of the lifting frame 101 and rotatably connected thereto. Multiple slots are spaced along the rotation direction on the outer top edge of the connecting frame 501 on the side opposite to the front hanger 102 or the rear hanger 103. One end of the limiting plate 502 is rotatably connected to the lifting frame 101 above the connecting frame 501, and the other end is inserted into and limited by the slots. This mechanical limiting allows for adaptive opening adjustment of the hanger feet, accommodating the width differences between the vehicle body and the spare parts frame 6, significantly improving the compatibility of the device.

[0028] Furthermore, the slots include a first slot 503, a second slot 504, and a third slot 505. The second slots 504 are located at both ends of the top outer edge of the connecting frame 501 and are used to adapt to the no-load running state. The first slot 503 and the third slot 505 are located between the two second slots 504. The first slot 503 is used to adapt to the vehicle body positioning, and the third slot 505 is used to adapt to the positioning of the parts frame 6. The design of multiple types of slots enables the device to adapt to different working states, improving the versatility and applicability of the device.

[0029] In some embodiments, the front positioning hole assembly 2 is located at the head of the base of the spare parts frame 6 and is used to engage with the front support pin 104 located on the top of the front hanger 102.

[0030] Specifically, the front positioning hole assembly 2 includes a first upper baffle 201, a first lower baffle 202, and a positioning cylinder 203. The first lower baffle 202 is located below the first upper baffle 201 and is detachably connected to it via several connecting bolts 4. The positioning cylinder 203 is fixed to the bottom of the first lower baffle 202. The bottom of the positioning cylinder 203 has a body-conforming positioning hole 204 (with a diameter of 20±0.1mm, consistent with the body lifting hole) that engages with the front support pin 104. The front support pin 104 passes through the positioning hole 204 and is inserted into the positioning cylinder 203 to achieve a limiting position. The positioning hole 204 is 100% matched with the body lifting support pin, achieving millimeter-level docking accuracy. In practical applications, the first upper baffle 201 is located on the upper surface of the spare parts frame 6 base, and the first lower baffle 202 is located on the lower surface of the spare parts frame 6 base. The first upper baffle 201 and the first lower baffle 202 are fixed together by connecting bolts 4. The front support pin 104 is located below the positioning cylinder 203 and is used to support the positioning cylinder 203 upwards. By loosening the connecting bolts 4, the position of the positioning hole 204 is adjustable, which is suitable for spare parts frames 6 of different widths and Y-axis dimensions of different vehicle models of lifting devices, thus improving positioning accuracy and compatibility.

[0031] In some embodiments, the rear pivot assembly 3 is located at the rear of the base of the spare parts frame 6, and is used to mate with the rear support structure 105 (50mm high, width matching the chassis pivot point ±1mm) located on top of the rear hanger 103. This clarifies the installation position and mating accuracy of the rear pivot assembly, providing support for improving its positioning accuracy.

[0032] Specifically, the rear support assembly 3 includes a second upper baffle 301, a second lower baffle 302, and a support member 303. The second lower baffle 302 is located below the second upper baffle 301 and is detachably connected to it via several connecting bolts 4. The support member 303 is fixed to the bottom of the second lower baffle 302, and its side wall has an elongated hole 304 for insertion into the rear support structure 105. In practical applications, the second upper baffle 301 is located on the upper surface of the spare parts frame 6 base, and the second lower baffle 302 is located on the lower surface of the spare parts frame 6 base. The second upper baffle 301 and the second lower baffle 302 are fixed together by connecting bolts 4. By loosening the connecting bolts 4, the position of the rear support assembly 3 is adjustable to accommodate spare parts frames 6 of different widths and Y-axis dimensions of different vehicle models' lifting devices, further improving the compatibility of the device.

[0033] Specifically, the rear support structure 105 includes a support leg 106, a U-shaped bracket 107, and an F-shaped pin 108. The support leg 106 is fixed to the top of the rear lifting foot 103, and the base plate of the U-shaped bracket is fixed to the top of the support leg 106. Through holes 109 are provided on both side plates of the U-shaped bracket. The support member 303 is located between the two side plates. A limiting baffle 110 is provided on the outside of one side plate of the U-shaped bracket 107. The F-shaped pin 108 is inserted into the through hole 109 and the elongated hole 304 to form a limiting relationship with the limiting baffle 110. During hoisting, the base plate of the U-shaped bracket provides upward support to the rear support assembly 3. This structure ensures the stability of the connection between the rear support assembly and the rear lifting foot, improving the reliability of the hoisting process.

[0034] The above structural design, by accurately simulating the vehicle body lifting structure, allows the spare parts frame 6 to be directly attached to the painting hanger 1, eliminating the need for detachment from the skid and secondary positioning, achieving rapid docking and significantly improving lifting efficiency.

[0035] In some embodiments, a method for hoisting the spare parts frame 6 is also provided, comprising: Pre-installation steps: According to the spare parts type, adjust the installation positions of the front positioning hole group 204 and the rear support assembly 3 on the spare parts frame 6, and fix them with connecting bolts 4; Adaptive docking procedure: Spare part frame 6 is transported to the designated position, and painting hoist 1 is lowered to 10cm below spare part frame 6. By rotating the lifting feet, the front support pin 104 is automatically aligned with the front positioning hole assembly 2, and the rear support structure 105 is aligned with the rear fulcrum assembly 3. The F-pin is then inserted into the rear fulcrum to complete the locking. This method is convenient to operate, shortens the hoisting time, and further improves hoisting efficiency.

[0036] In some embodiments, the present invention also provides a coating production line system, including the contour positioning and hoisting device in any of the above embodiments.
