Description

Technical Field

[0001] This invention relates to the field of tooling and fixture technology, and in particular to a tooling and fixture with a self-cleaning function. Background Technology

[0002] As core auxiliary equipment in industrial fields such as machining, parts assembly, and welding, tooling fixtures are mainly used to position and clamp workpieces during processing or assembly, ensuring that the workpieces maintain a stable posture during operation, guaranteeing machining accuracy, assembly quality, and work efficiency. They are widely used in various industries such as automobile manufacturing, electronics processing, mechanical parts production, and welding, and are an important support for promoting the standardization and efficiency of industrial production. In processing scenarios involving high-temperature operations such as welding and casting, tooling fixtures are in long-term contact with molten droplets generated during workpiece processing. These droplets adhere to the surface of the fixture. If they are not cleaned in time, it will lead to a decrease in the positioning accuracy of the fixture and insufficient clamping stability, which will affect the subsequent workpiece processing quality. At the same time, the residual molten droplets will also increase the wear of the fixture and shorten its service life. Therefore, effectively cleaning the molten droplets on the surface of tooling fixtures is an important link to ensure the normal use of tooling fixtures and maintain production continuity.

[0003] In actual industrial production scenarios, the molten droplet removal process of tooling fixtures faces numerous unresolved issues. Firstly, if the cleaning area lacks reliable fixation, it is prone to displacement, making it difficult to accurately align with the droplet attachment point, resulting in poor cleaning effectiveness. Residual droplets can still negatively impact the fixture's usability. Secondly, without a heating device, the molten droplets adhering to the fixture surface solidify and harden upon cooling, requiring significant manpower and time for cleaning, leading to low efficiency and severely hindering overall production progress. These problems are prevalent in existing technologies.

[0004] For example, patent CN117139951A discloses a tooling fixture with a self-cleaning function. The technical solution of this patent includes: a tooling fixture; a shovel bar located above the tooling fixture, capable of cleaning the surface of the tooling fixture; and a cleaning mechanism located above the tooling fixture, capable of driving the shovel bar to clean the surface of the tooling fixture. However, the cleaning structure of this patent lacks a fixing structure for the cleaning part during molten droplet cleaning, causing the cleaning part to easily shift and the cleaning effect to fail to meet usage requirements. Furthermore, the structure lacks a heating device, making it very labor-intensive to clean solidified molten droplets, increasing the labor intensity of operators, prolonging the cleaning cycle, and affecting the recycling efficiency of the tooling fixture. These problems frequently occur in industries that rely on tooling fixtures, such as welding and casting production, and have become key pain points restricting production efficiency and affecting processing quality.

[0005] Therefore, how to provide a tooling fixture with self-cleaning function is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] One object of the present invention is to provide a tooling fixture with a self-cleaning function.

[0007] According to an embodiment of the present invention, a tooling fixture with a self-cleaning function includes a mounting frame, on which four rotating plates and a double-headed electric cylinder are mounted. The two telescopic ends of the double-headed electric cylinder are respectively connected to a set of rotating components. Each set of rotating components is connected to two rotating plates. Two positioning components are respectively installed between the two rotating components. The positioning components are mounted on the mounting frame. Each rotating plate is respectively equipped with a clamping component and a heater.

[0008] The mounting frame is also equipped with a lifting cylinder, two lifting plates, and two rotating blocks. Two sets of collection components are fixedly installed on the telescopic end of the lifting cylinder. Each set of collection components is connected to a lifting plate. Each set of collection components is connected to a flipping component. Each set of flipping components is connected to a rotating block. The rotating block can limit the movement of the collection components.

[0009] Furthermore, the clamping assembly includes two clamping plates, both of which are mounted on a rotating plate. Each rotating plate is fixedly mounted with a drive shaft, which is slidably mounted on a mounting bracket. A sliding bracket is installed between every two drive shafts, and the sliding bracket is slidably mounted on the mounting bracket.

[0010] Furthermore, the mounting bracket is provided with two fourth mounting slots and two incomplete racks. The drive shaft is slidably mounted on the inner wall of the fourth mounting slot. The rotating component includes a moving gear, which is fixedly mounted on the outer surface of the drive shaft. The moving gear meshes with the incomplete rack. The incomplete rack does not have a tooth profile in the middle position. A moving frame is rotatably mounted on the lower part of the outer surface of the drive shaft. The moving frame is located below the moving gear. The two telescopic ends of the double-headed electric cylinder are fixedly connected to one of the moving frames.

[0011] Furthermore, the drive shaft is provided with positioning holes, and the positioning assembly includes a fixing block, which is fixedly installed on the inner wall of the fourth mounting groove. A positioning shaft is fixedly installed on each side of the fixing block, and the outer surface diameter of the positioning shaft is equal to the inner wall diameter of the positioning hole.

[0012] Furthermore, when the moving gear disengages from the incomplete rack, the positioning shaft and the positioning hole are coaxial.

[0013] Furthermore, the mounting frame is provided with two fifth mounting slots, and two lifting plates are slidably mounted on the inner wall of one of the fifth mounting slots. Two cleaning scrapers are fixedly mounted on the two opposite sides of the two lifting plates. The collection assembly includes a collection enclosure plate, which is fixedly mounted on the side of the lifting plate where the cleaning scraper is mounted. A portion of the blade of the cleaning scraper is located between the collection enclosure plate and the lifting plate. The cleaning scraper is located above the collection enclosure plate. A third mounting block is fixedly mounted on the lower side of the collection enclosure plate. A drive plate is fixedly mounted between the two third mounting blocks. The drive plate is fixedly connected to the telescopic end of the lifting electric cylinder.

[0014] Furthermore, when the telescopic end of the lifting cylinder is extended to its maximum length, the upper surface of the collecting plate coincides with the mounting frame.

[0015] Furthermore, two mounting shafts are rotatably mounted on the side of the mounting frame, and two rotating blocks are respectively fixedly mounted on the outer surfaces of the two mounting shafts. The flipping assembly includes a rotating shaft, and a transmission chain is connected between the rotating shaft and the mounting shaft to form a chain drive. A second connecting rod is fixedly mounted on the outer surface of the rotating shaft, and a first connecting rod is rotatably mounted on the end of the second connecting rod away from the rotating shaft. The end of the first connecting rod away from the second connecting rod is rotatably connected to the collecting enclosure.

[0016] Furthermore, the third mounting block has a positioning groove on its side, and a first locking block is fixedly installed on each of the two opposite sides of the two rotating blocks, and a second locking block is fixedly installed on each of the two opposite sides of the two rotating blocks. The cross-sectional dimensions of the second locking block are equal to the cross-sectional dimensions of the positioning groove.

[0017] Furthermore, when the collecting plate rises to the point where its upper surface is in contact with the mounting frame, the flipping component drives the first locking block to be perpendicular to the surface of the mounting frame. At this time, the upper surface of the rotating block coincides with the upper surface of the mounting frame, and the second locking block extends into the positioning slot. The length of the first locking block is equal to the distance between the lower surface of the rotating plate and the upper surface of the mounting frame.

[0018] The beneficial effects of the present invention are: (1) The present invention controls the rise of the collection plate and the cleaning scraper by the lifting electric cylinder to switch between two working states of the control rotating block. When the extension end of the lifting electric cylinder is retracted to the shortest position, the rotating block is positioned by the first locking block to be welded, thereby assisting the positioning of the welded parts by the plate and preventing the movement of the welded parts from affecting the welding effect. When the extension end of the lifting electric cylinder is extended to the longest position, the rotating block is limited by the second locking block to fix the cleaning scraper and the collection plate, thereby fixing the cleaning scraper to facilitate the cleaning scraper to remove the molten droplets on the surface of the plate and avoid the cleaning scraper shaking during the disassembly process, which would result in an unsatisfactory cleaning result. At the same time, the scraped molten droplets are collected by the collection plate.

[0019] (2) The present invention achieves the switching between two motion states of rotation and translation of the first mounting block by the cooperation of the double-headed electric cylinder and the positioning component. The rotation of the first mounting block enables the welding parts of different sizes to be limited by the sticking plate. The translation of the first mounting block enables the relative movement between the outer surface of the sticking plate and the cleaning scraper to remove the molten droplets. At the same time, the heater heats the molten droplet part, making the scraping easier. Attached Figure Description

[0043] In this embodiment, a lifting cylinder 401 is fixedly installed on the base plate 103, and two lifting plates 405 are slidably installed on the mounting plate 101.

[0045] In this embodiment, the collecting enclosure 407 has threaded holes on its side, and a baffle 408 is installed on the side of the collecting enclosure 407.

At this time, the double-headed electric cylinder 301 continues to drive the moving gear 305 to move. When the moving gear 305 disengages from the incomplete rack 303, the positioning shaft 221 contacts the inner wall of the positioning hole 212.

A first connecting block 505 is rotatably installed at the end of the first connecting rod 506 away from the second connecting rod 507. The first connecting block 505 is fixedly connected to the collecting enclosure plate 407.

[0050] Appendix Figure 5 To the attached Figure 11 .

[0051] In this embodiment, the third mounting block 404 has a positioning groove 403 on its side. A first locking block 503 is fixedly installed on each of the two opposite sides of the two rotating blocks 502, and a second locking block 504 is fixedly installed on each of the two back-to-back sides of the two rotating blocks 502. The cross-sectional dimensions of the second locking block 504 are equal to the cross-sectional dimensions of the positioning groove 403. When the collecting plate 407 rises to its upper surface and is in contact with the mounting plate 101, the flipping assembly causes the first locking block 503 to become perpendicular to the surface of the mounting plate 101. At this time, the upper surface of the rotating block 502 coincides with the upper surface of the mounting plate 101, and the second locking block 504 extends into the positioning groove. The first clamping block 503 is placed inside the groove 403 and fits against the inner wall of the positioning bracket 403. The length of the first clamping block 503 is equal to the distance between the lower end face of the rotating plate 201 and the upper end face of the mounting plate 101. The welding part to be welded is placed between the two first clamping blocks 503. Then the double-headed electric cylinder 301 is started. The double-headed electric cylinder 301 drives the two moving gears 305 to move along the incomplete rack 303 through the moving frame 304, thereby driving the rotating plate 201 to gradually move closer together. The welding part is clamped and limited by the sticking plate 206. At the same time, the first clamping block 503 plays an auxiliary limiting role. During the welding process, some molten droplets will drip onto the sticking plate 206.

[0052] During the upward movement of the collection panel 407, the first connecting rod 506 drives the rotating shaft 510 to rotate, which in turn drives the rotating block 502 to rotate via the transmission chain 508. This causes the second locking block 504 to extend into the positioning slot 403, and the second locking block 504 fixes the cleaning scraper 406, making it easier for the cleaning scraper 406 to remove and clean the molten droplets on the surface of the plate 206. This prevents the cleaning scraper 406 from shaking during the disassembly process, which could lead to unsatisfactory cleaning results.

[0053] Working principle:

[0054] (i) The welding parts to be welded are placed between the two first clamping blocks 503. Then the double-headed electric cylinder 301 is started. The double-headed electric cylinder 301 drives the two moving gears 305 to move along the incomplete rack 303 through the moving frame 304, thereby driving the rotating plate 201 to gradually move closer to each other. The welding parts are clamped and limited by the sticking plate 206. At the same time, the first clamping block 503 plays an auxiliary limiting role. During the welding process, some molten droplets will drip onto the sticking plate 206.

[0055] (ii) After welding, the welded parts are removed from the mounting plate 101. Then, the lifting cylinder 401 is activated. The lifting cylinder 401 drives the lifting plate 405 and the collecting plate 407 to rise via the driving plate 402. When the telescopic end of the lifting cylinder 401 is extended to its maximum length, the collecting plate 407 is in contact with the lower end face of the mounting plate 101. At this time, the double-headed cylinder 301 continues to drive the moving gear 305 to move. When the moving gear 305 disengages from the incomplete rack 303, the positioning shaft 221 contacts the inner wall of the positioning hole 212. Then, the double-headed cylinder 301 drives the transmission shaft 210 to reciprocate along the positioning shaft 221.

[0056] (iii) At the same time as the lifting cylinder 401 is started, the heater 219 is started. The heater 219 heats the molten droplet part on the sticking plate 206. The cleaning scraper 406 scrapes off the molten droplet part on the sticking plate 206. Heating the molten droplet part makes it easier to scrape off the molten droplet part. The scraped-off molten droplet falls between the collecting plate 407 and the lifting plate 405.

[0057] (iv) During the process of collecting the surrounding plate 407 rising, the first connecting rod 506 drives the rotating shaft 510 to rotate, which in turn drives the rotating block 502 to rotate through the transmission chain 508, so that the second locking block 504 extends into the positioning slot 403. The second locking block 504 fixes the cleaning scraper 406, which makes it easier for the cleaning scraper 406 to remove the molten droplets on the surface of the plate 206 and avoids the cleaning scraper 406 from shaking during the disassembly process, which would result in an unsatisfactory cleaning result.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
