Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a double-sided machining clamping device. Background Technology

[0002] Castings have a long history of application. In ancient times, people used castings to make household utensils. In modern times, castings are mainly used as blanks for machine parts. Some precision castings can also be used directly as machine parts. Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling, it is processed by grinding and other subsequent processing methods to obtain an object with a certain shape, size and performance. After the casting is taken out of the mold, it needs to be processed by subsequent processing, such as grooving and drilling, in order to meet the subsequent use requirements.

[0003] In the grooving and drilling processes of castings, fixtures are needed to clamp them. However, existing fixtures can only clamp one casting at a time. During the processing, a lot of time is spent disassembling and assembling the fixture from the machine tool, resulting in low work efficiency and failing to meet the needs of enterprise development.

[0004] To address the aforementioned problems, this application discloses a double-sided machining clamping device. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model discloses a double-sided processing clamping device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a double-sided processing clamping device, including a stand, a flipping platform, a flipping drive assembly, and two clamping assemblies; The stand is used for mounting with a machine tool, and a circular groove is provided in the middle of the stand. The flipping platform is rotatably mounted inside the circular groove via a shaft. Several anti-rotation components are provided between the flipping platform and the stand to fix the flipping platform after it is flipped. The flipping drive assembly is located on the back of the stand and connected to the flipping platform; The two clamping components are respectively located on both sides of the flipping platform.

[0007] More preferably, the two clamping components have the same structure, and the clamping component includes several pads distributed on the flipping platform and several pressing components corresponding to the several pads disposed on the flipping platform.

[0008] More preferably, the clamping assembly includes a guide post disposed on the flipping platform, a clamping plate inserted into the guide post through a guide hole, a clearance hole disposed on the clamping plate, a screw rod disposed on the stand through the clearance hole, and a nut screwed onto the top of the screw rod above the clamping plate.

[0009] More preferably, the anti-rotation assembly includes several anti-rotation blocks disposed on both sides of the tilting platform and several telescopic drive cylinders disposed on the rear side of the stand, the number of which is the same as the number of anti-rotation blocks on the rear side of the stand. The anti-rotation blocks have slots on the side facing outward, and the piston rods of the telescopic drive cylinders are connected to tongues. When the tilting platform is fixed, the telescopic drive cylinders drive the tongues to be inserted into the slots.

[0010] More preferably, the front side of the stand is provided with a mounting groove, the shaft connected to the flipping platform extends into the interior of the mounting groove, and the flipping drive assembly includes a first bevel tooth mounted on one end of the shaft in the mounting groove, a reduction motor corresponding to the mounting groove and located on the rear side of the stand, and a second bevel tooth mounted in the mounting groove on the output shaft of the reduction motor and meshing with the first bevel tooth.

[0011] A further preferred embodiment is that the bottom of the stand has a horizontal mounting plate, and the horizontal mounting plate has waist-shaped holes on all four sides.

[0012] This utility model achieves the following beneficial effects: The double-sided machining clamping device provided in this application can clamp two castings at a time.

Example

[0018] To address the problems of existing fixtures that can only clamp a single casting at a time, resulting in significant time waste and low work efficiency, this paper references... Figures 1-4 As shown, this application discloses a double-sided processing clamping device, including a stand 10, a flipping platform 20, a flipping drive assembly 30, and two clamping assemblies 40; The stand 10 is used for mounting with the machine tool, and a circular groove 11 is provided in the middle of the stand 10. The flipping platform 20 is rotatably disposed inside the circular groove 11 via the shaft 21. Several anti-rotation components 50 are provided between the flipping platform 20 and the stand 10 for fixing the flipping platform 20 after it is flipped. The flip drive assembly 30 is located on the back of the stand 10 and connected to the flip platform 20; Two clamping components 40 are respectively disposed on both sides of the flipping platform 20; In practice, the operator first loads the two castings to be processed onto the flipping platform 20 using the two clamping components 40. Then, the entire double-sided processing clamping device is hoisted onto the machine tool. After that, the machine tool will process one casting at the processing position. After the processing of this casting is completed, the anti-rotation component 50 stops fixing the flipping platform 20, and the flipping drive component 30 drives the flipping platform 20 to rotate 180° (after the flipping platform 20 changes sides, the anti-rotation component 50 continues to fix the flipping platform 20). Finally, the machine tool will process the next casting at the processing position. After the processing of these two castings is completed, the double-sided clamping device can be removed from the machine tool and lifted away.

[0019] In one specific embodiment, the two clamping components 40 of this application have the same structure. The clamping component 40 includes several pads 41 distributed on the flipping platform 20 and several pressing components 42 corresponding to the several pads 41 set on the flipping platform 20. The pressing component 42 includes a guide post 421 set on the flipping platform 20, a pressing plate 422 inserted into the guide post 421 through a guide hole 4221, a clearance hole 4222 opened on the pressing plate 422, a screw rod passing through the clearance hole 4222 and set on the stand 10, and a nut 424 423 screwed on the top of the screw rod above the pressing plate 422. When clamping the casting, the operator places the casting vertically on the surface of the flipping platform 20. By tightening the nut 424, the pressure plate can be lowered until the product is pressed and the casting can be fixed.

[0020] To facilitate the clamping of castings by operators, auxiliary blocks can be set on the lower sides of the flipping platform 20, and the castings can be placed on the auxiliary blocks during the actual clamping process.

[0021] In one specific embodiment, the anti-rotation component 50 of this application includes several anti-rotation blocks 52 disposed on both sides of the tilting platform 20 and several telescopic drive cylinders 51 disposed on the rear side of the stand 10 and in the same number as the anti-rotation blocks 52 on the rear side of the stand 10. The anti-rotation block 52 has a slot 521 on the side facing outward. The piston rod of the telescopic drive cylinder 51 is connected to a tongue 511. When the tilting platform 20 is fixed, the telescopic drive cylinder 51 drives the tongue 511 to insert into the slot 521. In a specific implementation, when the machine tool finishes processing a casting, the tilting drive component 30 drives the tilting platform 20 to rotate 180°. After the tilting action is completed, the several telescopic drive cylinders 51 can drive the tongue 511 to insert into the slot 521 of the anti-rotation block 52.

[0022] In one specific embodiment, the present application provides a mounting groove 12 on the front side of the stand 10. The shaft 21 connected to the flipping platform 20 extends into the interior of the mounting groove 12. The flipping drive assembly 30 includes a first bevel tooth 31 mounted on one end of the shaft 21 in the mounting groove 12, a reduction motor 32 located on the rear side of the stand 10 corresponding to the mounting groove 12, and a second bevel tooth 33 mounted on the output shaft of the reduction motor 32 in the mounting groove 12 and meshing with the first bevel tooth 31. When the flipping platform 20 is driven to flip, the reduction motor 32 drives the first bevel tooth 31 to rotate, causing the second bevel tooth 33 to rotate. In this way, the shaft 21 will carry the flipping platform 20 to flip, thereby enabling the two clamping assemblies 40 provided on the flipping platform 20 to change sides.

[0023] To facilitate the fixing of the entire clamping device of this application to the machine tool, this application has a horizontal mounting plate 60 at the bottom of the stand 10. The horizontal mounting plate 60 has waist-shaped holes 61 on all four sides. When fixing it to the machine tool, the operator can screw bolts through the waist-shaped holes 61 to fix it to the machine table on the machine tool.
