Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a painting device for mechanical processing. Background Technology

[0002] In the field of modern machining, painting plays a crucial role as a key step in improving workpiece surface quality, enhancing protective performance, and giving it an aesthetically pleasing appearance. With the rapid development of the manufacturing industry, more stringent requirements have been placed on the quality and production efficiency of machined products, making the performance and automation level of painting equipment a focus of industry attention.

[0003] However, existing technologies, such as Chinese Publication No. CN213914436U, disclose a painting device for machining, which relates to the field of machining equipment technology. This painting device for machining includes a support platform, a painting frame fixedly connected to one side of the support platform, a fixing plate fixedly connected to the top of the painting frame, a cylinder fixedly connected to one side of the fixing plate, movable blocks fixedly connected to both sides of the top of the painting frame, one side of the cylinder fixedly connected to the movable block, an electric slide rail fixedly connected between the movable blocks, a control box provided on one side of the electric slide rail, and the movable box slidably connected to the outside of the electric slide rail.

[0004] This invention enables automated painting of mechanical parts, eliminating the need for manual spraying with a handheld spray gun. It achieves omnidirectional painting without requiring users to repeatedly adjust the workpiece angle, effectively improving painting efficiency and quality, and significantly enhancing the practicality of painting equipment for machining. However, in practice, it has been found that this device requires frequent manual flipping of the workpiece, which not only consumes significant labor costs but also greatly reduces production efficiency. Operators need to constantly monitor the painting progress and flip the workpiece as needed. This process is not only monotonous and tedious but also prone to operator fatigue, increasing the probability of errors. Furthermore, manual operation makes it difficult to ensure that the timing and angle of each flip are completely consistent, resulting in differences in the amount and uniformity of paint applied to different surfaces of the workpiece, severely affecting the stability of the painting quality. In addition, frequent manual contact with the workpiece may cause secondary contamination or damage to the already painted surface. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology that require frequent manual flipping, resulting in low efficiency, unstable quality, and easy contamination and damage to the workpiece.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a painting device for machining, comprising: a mounting platform; a collection box installed in a slot at the upper end of the mounting platform; mounting frames installed on the left and right sides of the slot on the mounting platform; a clamping assembly installed between a set of mounting frames; a flipping assembly installed on fixed arms on the left and right sides of the clamping assembly, which allows the workpiece to flip along its central axis; a fixed frame located above the mounting platform, with a movable slot extending through its upper center; and a spraying assembly located in the movable slot, with a spraying auxiliary assembly around its periphery and an adjustment assembly at its bottom, which allows the spraying assembly to move along the axial direction.

[0007] The technical advantages of the above-mentioned further solution are as follows: the device recovers paint through the collection box of the mounting platform, the clamping component on the mounting frame fixes the workpiece, the flipping component enables the workpiece to flip along the central axis, the spraying component in the movable slot of the fixed frame can move axially in conjunction with the adjustment component, and the spraying auxiliary component enhances the effect, which can efficiently complete the all-round and uniform spraying of the workpiece, and is both practical and environmentally friendly.

[0008] In a preferred embodiment, the clamping assembly includes: two clamping blocks, which are mounted opposite each other on the side of a set of mounting brackets, with a placement groove in their middle; multiple screws, one end of which passes through the upper end of the clamping blocks and extends into the placement groove; an abutment block connected to the lower end of the screw; and a handwheel connected to the upper end of the screw.

[0009] The technical advantage of the above-mentioned further solution is that the workpiece is supported by two opposing clamping blocks and a central placement groove. Rotating the handwheel drives multiple sets of screws to move downwards, causing the abutment blocks to tightly press against the workpiece, achieving stable clamping. The structure is simple and easy to operate, and it can adapt to workpieces of different sizes, providing reliable support for the stable fixation and flipping of the workpiece during subsequent painting processes.

[0010] In a preferred embodiment, the flipping assembly includes: a gear disposed on one side of the fixed arm; a connecting shaft disposed on one side of the gear, with its other end passing through the fixed arm and fixedly connected to the clamping block; a rack disposed below the gear and engaging with the gear; and a hydraulic shaft disposed at the end of the rack, with its output end fixedly connected to the rack via a telescopic rod, allowing the rack to move along the axial direction of the telescopic rod, thereby meshing and driving the gear to rotate around the axial direction of the connecting shaft.

[0011] The technical effect of adopting the above-mentioned further solution is that the hydraulic shaft drives the telescopic rod to move the rack, the rack meshes with the gear to rotate, and the gear drives the clamping block and the workpiece to rotate around the axis through the connecting shaft.

[0012] In a preferred embodiment, the spraying assembly includes: a paint storage tank, disposed above the fixed frame; a delivery pipe, disposed below the paint storage tank and communicating with the paint storage tank; a spraying frame, connected to the other end of the delivery pipe, with multiple spray nozzles fixedly connected to its upper end; and a pressure regulating valve, disposed in the middle of the delivery pipe.

[0013] The technical advantages of adopting the above-mentioned further solution are as follows: paint is stored in a paint storage tank, and then transported to the spraying frame via a delivery pipe, with multiple spray nozzles simultaneously spraying paint. The pressure regulating valve in the middle of the delivery pipe can precisely control the paint pressure, ensuring a stable and uniform spraying volume.

[0014] In a preferred embodiment, the adjusting assembly includes: a connecting block symmetrically connected to the bottom of the paint storage tank; a fixing seat disposed on the front and rear sides of the paint storage tank, with two transmission screws symmetrically arranged between the two fixing seats; a first pulley disposed at one end of the transmission screw, with a second pulley disposed on one side of the first pulley, and the two being connected by a transmission belt; and a drive motor disposed on one side of the first pulley, with its output end connected to the first pulley via a shaft; wherein the first pulley and the second pulley are respectively connected to the ends of the two transmission screws.

[0015] The technical effect of adopting the above-mentioned further solution is that the first pulley is driven by the drive motor, and the second pulley is linked by the transmission belt, so that the two transmission screws rotate synchronously, driving the connecting block, paint storage box and spraying frame to move along the screw axis.

[0016] In a preferred embodiment, the spraying auxiliary component includes: a suction hood disposed on the left and right sides of the spraying frame; and a suction wheel disposed on the suction hood.

[0017] The technical advantages of adopting the above-mentioned further solution are: by using the suction hoods on both sides of the spray booth in conjunction with the suction wheels, paint mist and odors generated during the painting process can be promptly removed. This effectively reduces paint mist diffusion pollution, improves the working environment, and prevents excess paint from adhering and affecting the painting quality of the workpiece.

[0018] In a preferred embodiment, the spraying auxiliary component further includes: a heating cover disposed on the front and rear sides of the spraying frame; and an electric heating tube disposed in the heating cover.

[0019] The technical effect of adopting the above-mentioned further solution is that the heating tube generates heat during the painting process, which heats the sprayed area of ​​the workpiece through the heating cover, accelerates the drying and curing of the paint, and reduces paint surface defects.

[0020] In a preferred embodiment, the bottom of the fixing frame is provided with a fixing column, and a caster wheel is fixedly connected to the bottom of the fixing frame. A movable column is movably provided on the outside of the fixing column and the movable column. A through hole is provided through the fixed column and the movable column, and a limit bolt is movably provided in the through hole.

[0021] The technical advantages of adopting the above-mentioned further solution are: the fixed column is equipped with casters to facilitate the movement of the device, the external movable column can adjust the height of the fixed frame, and the through holes of the fixed column and the movable column are locked and fixed by limit bolts.

[0022] In one preferred embodiment, the left and right sides of the rack are connected to limit blocks, which cooperate with the limit guide rails provided on the mounting frame.

[0023] The technical advantage of adopting the above-mentioned further solution is that the limiting blocks on both sides of the rack cooperate with the limiting guide rails of the mounting bracket to guide and limit the rack when it is driven to move by the hydraulic shaft. This effectively prevents the rack from deviating and disengaging from the gear, ensuring transmission stability and guaranteeing accurate and reliable power transmission of the tilting assembly.

[0024] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0025] 1. This utility model automates the workpiece flipping process using a flipping component, effectively solving the inefficiency problem caused by frequent manual flipping in existing technologies. Existing technologies require manual workpiece flipping after machine shutdown, interrupting the painting process and necessitating workpiece repositioning, significantly increasing processing time. In this device, a hydraulic shaft drives a telescopic rod to move a rack and pinion. Through gear and connecting shaft transmission, the clamping block and workpiece can be directly and precisely flipped along the central axis. The entire process requires no manual intervention, and the flipping angle can be precisely controlled by the hydraulic shaft stroke. Simultaneously, the limiting blocks on both sides of the rack and pinion cooperate with the limiting guide rails on the mounting frame to ensure a smooth and stable flipping process, avoiding uneven paint film thickness caused by uneven force or positioning deviations during manual flipping, and significantly improving the stability of the painting quality.

[0026] 2. This utility model achieves a completely non-contact processing of the workpiece from clamping to coating completion through the synergistic action of the clamping and flipping components. The clamping component, through mechanical fixing with screws and abutment blocks, can firmly clamp the workpiece without damaging its surface; the automated transmission structure of the flipping component replaces manual contact, avoiding the risk of contamination. Furthermore, the coating component, in conjunction with the adjusting component, achieves uniform spraying along the axial direction. Combined with the auxiliary functions of the suction hood and heating hood, it further reduces paint film defects caused by improper manual operation, improving operational safety while ensuring workpiece surface quality.

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.

[0035] Example 1:

[0036] Please see Figure 1-4 This utility model provides a technical solution: a painting device for machining, including a mounting platform 1, a collection box 2 installed in the upper slot of the mounting platform 1, and mounting brackets 3 installed on the left and right sides of the slot.

[0037] A clamping assembly 4 is provided between a set of mounting brackets 3. The clamping assembly 4 includes two clamping blocks 401 installed opposite each other. A placement groove 405 is provided in the middle of the clamping block 401. One end of multiple screws 402 passes through the upper end of the clamping block 401 and extends to the placement groove 405. The lower end of the screws 402 is connected to the abutment block 404, and the upper end is connected to the handwheel 403.

[0038] A flipping assembly 5 is installed on the fixed arms 8 on both sides of the clamping block 401. The flipping assembly 5 includes a gear 501, a connecting shaft 502, a rack 503, and a hydraulic shaft 504. One end of the connecting shaft 502 is connected to the gear 501, and the other end passes through the fixed arm 8 and is fixed to the clamping block 401. The rack 503 cooperates with the gear 501. The hydraulic shaft 504 drives the rack 503 to move through the telescopic rod 505 to achieve workpiece flipping.

[0039] The upper movable groove 9 of the fixed frame 21 above the mounting platform 1 is equipped with a spraying component 6, and the bottom adjustment component 7 of the spraying component 6 can drive it to move along the axis.

[0040] Example 2:

[0041] like Figures 1-5 As shown, based on Embodiment 1, in this painting device for machining, the clamping assembly 4 between the mounting brackets 3 on the mounting platform 1 fixes the workpiece through the screw 402, handwheel 403 and abutment block 404.

[0042] The flipping component 5 on the two fixed arms 8 of the clamping component 4 allows the workpiece to flip along the central axis. The limit blocks 19 on the left and right sides of the rack 503 cooperate with the limit guide rails 18 on the mounting frame 3 to ensure stable movement.

[0043] The spraying assembly 6 is installed in the movable slot 9 of the fixed frame 21 above the mounting platform 1. The spraying assembly 6 includes a paint storage tank 601, a delivery pipe 602, a spraying frame 604, a pressure regulating valve 603, and a spraying nozzle 605.

[0044] The delivery pipe 602 connects the paint storage tank 601 and the spray frame 604. The spray frame 604 is provided with spraying auxiliary components around its periphery, including suction hoods 10 and suction wheels 11 arranged on the left, right, front and back, as well as heating hoods 12 and electric heating tubes 13.

[0045] The adjustment component 7 at the bottom of the spraying component 6 includes a connecting block 701, a transmission screw 702, a fixed base 703, a first pulley 704, a second pulley 705, a transmission belt 706, and a drive motor 707, which can drive the spraying component 6 to move along the axial direction.

[0046] Example 3:

[0047] like Figures 1-5As shown, based on embodiment 2, the clamping assembly 4 between the mounting brackets 3 uses a handwheel 403 to rotate the screw 402, so that the abutment block 404 presses the workpiece.

[0048] The hydraulic shaft 504 of the two-sided flipping assembly 5 drives the rack 503 to rotate the gear 501, thereby achieving workpiece flipping.

[0049] The bottom of the fixed frame 21 is provided with a fixed column 14, the bottom of the fixed column 14 is connected to a universal wheel 17, and a movable column 15 is movably sleeved on the outside. The through holes 20 on the fixed column 14 and the movable column 15 are adjusted by the limit bolts 16 to adjust the height of the fixed frame 21.

[0050] The spraying assembly 6 moves along the axis by adjusting the transmission screw 702 and the drive motor 707 of the assembly 7 to ensure uniform spraying.

[0051] Working Principle: This equipment is a painting device for machining. During use, the workpiece to be painted is first placed in the placement slot 405 of the clamping assembly 4. The handwheel 403 at the upper end of the clamping block 401 is rotated, causing the screw 402 to move downwards, gradually bringing the lower abutment block 404 closer to the workpiece surface until the workpiece is securely clamped in the placement slot 405, ensuring that the workpiece will not shift during subsequent operations. Simultaneously, check that the collection box 2 in the slot at the upper end of the mounting table 1 is properly installed to collect any paint dripping during the painting process.

[0052] Next, adjust the height of the fixed frame 21. According to the size and specifications of the workpiece, loosen the limiting bolts 16 in the through holes 20 on the fixed column 14 and the movable column 15, move the fixed frame 21 up and down to a suitable height, and then tighten the limiting bolts 16 to complete the fixation. If it is necessary to move the device, the universal wheels 17 at the bottom of the fixed column 14 can be used to push the device to the designated working position.

[0053] Next, parameter settings are performed before spraying. An appropriate amount of paint is added to the paint storage tank 601, and the connection of the delivery pipe 602 is checked for tightness. A suitable spraying pressure is set by adjusting the pressure regulating valve 603. According to the spraying requirements, the drive motor 707 of the adjusting component 7 is started. The motor drives the transmission screw 702 to rotate via the first pulley 704, the second pulley 705, and the transmission belt 706, causing the spraying component 6 to move along the movable groove 9 to the initial spraying position.

[0054] During the actual spraying process, the spraying assembly 6 is activated, and the paint is sprayed out from the spray nozzle 605 of the spray frame 604 through the delivery pipe 602. Simultaneously, the spraying auxiliary assembly is activated, and the suction hoods 10 and suction wheels 11 on both sides begin to work, promptly removing the exhaust gases generated during spraying. If faster paint drying is required, the electric heating tubes 13 inside the front and rear heating hoods 12 can be activated. During the spraying process, the spraying assembly 6 is continuously driven to move along the axial direction by the adjusting assembly 7, achieving uniform spraying of the workpiece surface.

[0055] When it is necessary to paint the other side of the workpiece, the hydraulic shaft 504 of the flipping assembly 5 is activated. Its output end pushes the rack 503 along the limiting guide rail 18 via the telescopic rod 505. The rack 503 meshes with the drive gear 501 and rotates around the connecting shaft 502, causing the clamping block 401 and the workpiece to flip along the central axis to the required angle. The limiting blocks 19 on both sides of the rack 503 ensure smooth and precise movement. After flipping, the above painting steps are repeated to paint the other side of the workpiece.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
