Abstract
Description
Technical Field
[0001] This utility model relates to the field of pneumatic clamping, and in particular to a pneumatic clamping device for processing oil pans. Background Technology
[0002] As a critical component of automotive engines or transmissions, the oil pan, after being integrally formed (such as by stamping, die casting, or injection molding), often has burrs, flash, or sharp edges. These defects not only affect the product's appearance but can also cause poor sealing, safety hazards, or even cuts to operators during subsequent assembly or actual use. Therefore, meticulous cleaning of these edges (deburring) is an indispensable part of the production process. For oil pans with large curvature variations and complex shapes, these fixing points are difficult to effectively fit the entire edge to be deburred. When the curvature of the oil pan does not match the fixture design, it may result in insecure clamping, wobbling, or even failure to clamp. When the production line needs to switch between different models of oil pans, traditional pneumatic fixtures require manual mold changes, clamping position adjustments, or replacement of the entire fixture. Long-term repetitive alignment operations can easily lead to employee fatigue, increase operational errors, and consequently affect the quality and efficiency of deburring. Utility Model Content
[0003] The purpose of this utility model is to solve the problem of unreliable clamping and shaking caused by the poor applicability of current pneumatic clamping, which requires changing the mold, adjusting the clamping position or replacing the entire fixture. Therefore, a pneumatic clamping device for oil pan processing is proposed.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a support frame, the support frame includes two mounting seats arranged vertically, the distance between the two mounting seats is adjustable, the bottom mounting seat is rotatably connected to an upper support mechanism, and the top mounting seat is rotatably connected to a lower pressing mechanism. Both the upper support mechanism and the lower pressing mechanism include rod seats, and multiple support rods are vertically slidably mounted on the rod seats. The bottom of the upper support mechanism is fixedly equipped with a driver for driving the extension and retraction of the support rod, and a compression plate for fixing the support rod is slidably mounted on the rod seat.
[0005] As a further description of the above technical solution: the mounting base is rotatably connected to a turntable, the upper support mechanism and the lower pressing mechanism are fixed on the turntable, horizontal tubes are fixed on both sides of the mounting base, a horizontal rod is slidably inserted in the horizontal tube, and a locking bolt that abuts against the horizontal rod is threaded on the horizontal tube. The upper and lower horizontal rods are connected by a cylinder.
[0006] As a further description of the above technical solution: the rod seat is vertically provided with multiple rod holes one, the extrusion plate is vertically provided with multiple rod holes two corresponding to the rod holes one, and the support rod is adapted to the rod holes one and the rod holes two; The rod holder is fixed with multiple cylinders for pushing the extrusion plate.
[0007] As a further description of the above technical solution: the rod seat and the turntable are connected by multiple cylinders.
[0008] As a further description of the above technical solution: the driver includes an air disc and an air nozzle, the air disc being fixed below the bottom rod seat.
[0009] As a further description of the above technical solution: the support end of the support rod is fixed with a rubber head, and the surface of the support rod is covered with a rubber sleeve.
[0010] As a further description of the above technical solution: the rod seat has a plate opening in the transverse direction that is adapted to the extrusion plate.
[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This application utilizes multiple support rods to regionally compress the oil pan, ensuring a uniform distribution of clamping force and preventing localized deformation or vibration of the workpiece. Combined with the adjustable height and width of the support frame, and the multi-stage spacing adjustment of cylinder one and cylinder two, the device can quickly and effectively compress oil pans of various sizes, shapes, and curvatures. This completely solves the pain points of poor applicability and frequent replacement required by traditional fixtures. The rotating connection between the upper support mechanism and the lower pressing mechanism and the mounting base allows the compressed oil pan to rotate with the turntable. This greatly facilitates 360° processing of the oil pan edge without dead angles using deburring and other processing tools, eliminating the need for secondary clamping and improving processing flexibility and efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0015] like Figure 1 - Figure 8 As shown, this utility model provides a pneumatic clamping device for processing oil pans, including a support frame 10. The support frame 10 includes two mounting seats 11 arranged vertically, with an adjustable distance between the two mounting seats 11. The bottom mounting seat 11 is rotatably connected to an upper support mechanism 20, and the top mounting seat 11 is rotatably connected to a lower pressing mechanism 30. Both the upper support mechanism 20 and the lower pressing mechanism 30 include rod seats 21, with multiple support rods 25 slidably mounted vertically on the rod seats 21. A driver 40 for driving the extension and retraction of the support rods 25 is fixedly installed at the bottom of the upper support mechanism 20. The driver 40 supports the multiple support rods 25 on the upper support mechanism 20, so that the bottom support rods 25 adapt to the shape of the bottom wall of the oil pan. The support rod 25 above the shell conforms to the shape of the top of the oil pan by abutting against its upper surface. Finally, the support rod 25 is fixed to the rod seat 21 by a pressing plate 22 that slides on the rod seat 21. Finally, the oil pan is pressed between the upper and lower support rods 25 by adjusting the height of the two mounting seats 11. The oil pan is pressed in a regional manner by the vertical sliding of multiple support rods 25 and rod seat 21 and by the combined action of multiple support rods 25, so that the whole can adapt to oil pans of different sizes and shapes. At the same time, the pressed oil pan is rotatably connected to the mounting seat 11 through the upper support mechanism 20 and the lower pressing mechanism 30 to facilitate the rotation and processing of the oil pan.
[0016] like Figure 3 , Figure 4As shown, a turntable 12 is rotatably connected to the mounting base 11. A shaft 121 is coaxially fixed to the turntable 12. The shaft 121 is rotatably connected to the mounting base 11 via a bearing. The upper support mechanism 20 and the lower pressing mechanism 30 are fixed on the turntable 12. Horizontal tubes 13 are fixed on both sides of the mounting base 11. A horizontal rod 14 is slidably inserted into the horizontal tube 13. Locking bolts 131 that abut against the horizontal rod 14 are threaded onto the horizontal tube 13. The upper and lower horizontal rods 14 are connected by cylinders 15. The distance between the two cylinders 15 can be adjusted by sliding the horizontal rod 14 within the horizontal tube 13, thereby adjusting the width of the support frame 10 for oil pans of different lengths. This prevents the cylinders 15 from interfering with the rotation of the oil pan. The cylinder body of cylinder 15 is vertically fixed to the bottom horizontal rod 14, and the piston rod is vertically fixed to the top horizontal rod 14. The extension and retraction of cylinder 15 drives the lifting and lowering of the lower pressing mechanism 30.
[0017] like Figure 5 , Figure 7 As shown, the rod base 21 has multiple rod holes 211 vertically, and the extrusion plate 22 has multiple rod holes 221 corresponding to the rod holes 211 vertically. The support rod 25 is adapted to the rod holes 211 and the rod holes 221. Multiple cylinders 24 are fixed on the rod base 21 to push the extrusion plate 22. The cylinders 24 extend and retract in a direction perpendicular to the support rod 25. The extrusion plate 22 slides horizontally on the rod base 21 and inserts the support rod 25 into the corresponding rod hole 211 and rod hole 221. The piston rod of the cylinder 24 extends and pushes the extrusion plate 22. At this time, under the extrusion action of the inner wall of the rod hole 221, the support rod 25 is fixed on the rod base 21.
[0018] like Figure 3 , Figure 5 As shown, the rod seat 21 and the turntable 12 are connected by multiple vertically arranged cylinders 23. The rod seat 21 is initially adjusted by cylinder 15, and then adjusted again by cylinder 23.
[0019] like Figure 1 , Figure 8 As shown, the actuator 40 includes an air plate 41 and an air nozzle 42. The air plate 41 is fixed below the bottom rod seat 21 and communicates with the rod hole 211 of the bottom rod seat 21. The air nozzle 42 is a quick-connect male connector. The air nozzle 42 is connected to the female connector of the quick-connect connector of the air pump so that the air pump can pressurize the air plate 41 and cause the bottom support rod 25 to rise under the action of air pressure and fit against the bottom of the oil pan.
[0020] like Figure 1 , Figure 7As shown, a rubber head 26 is fixed to the support end of the support rod 25. The rubber head 26 buffers the support surface to avoid squeezing damage to the oil pan. A rubber sleeve 251 is provided on the surface of the support rod 25 to improve the squeezing reliability of the squeezing plate 22 on the support rod 25 when the squeezing plate 22 squeezes the support rod 25.
[0021] like Figure 5 , Figure 6 As shown, the rod seat 21 has a horizontally opened plate opening 212 that is adapted to the extrusion plate 22, so as to slide and position the extrusion plate 22 through the plate opening 212.
[0022] Working principle: The air nozzle 42 is connected to an external air pump, which pressurizes the air plate 41. Under the action of air pressure, the multiple support rods 25 at the bottom will rise synchronously. When the oil pan is placed on top of them, these support rods 25 will move up independently until they contact the bottom wall of the oil pan. They will adaptively abut and support the oil pan according to the complex curvature of the bottom wall. The support rods 25 above the oil pan abut against the top wall of the oil pan through their upper surface, adaptively conforming to the shape of the top of the oil pan. Combined with the extension and retraction of the cylinder 15, the entire pressing mechanism 30 can be driven to descend, so that the multiple support rods 25 at the top press down on the oil pan. After the oil pan is adaptively abutted and pressed into place by the upper and lower sets of support rods 25, multiple cylinders 24 are fixed on each rod seat 21. These cylinders 24 extend and retract in a direction perpendicular to the support rods 25. A pressing plate 22 is also horizontally slidably mounted on the rod seat 21. The pressing plate 22 has rod holes 221 corresponding to the support rods 25. The support rods 25 pass through rod holes 211 and 221. At this time, the piston rod of the cylinder 24 extends, pushing the pressing plate 22 to slide horizontally. Under the pressing action of the inner wall of the rod hole 221, the pressing plate 22 applies lateral pressure to the support rods 25 passing through it, thereby firmly fixing multiple support rods 25 to the rod seat 21.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
