Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a flattening processing device for machined parts. Background Technology

[0002] According to the patent document with publication number CN 222471843 U, the height of the T-shaped adjusting plate is adjusted according to the thickness and size of the machined part, and then the clamping position of the clamping block is adjusted. During adjustment, the adjusting cylinder is activated, which pulls the T-shaped adjusting plate downward until the top of the T-shaped adjusting plate is lower than the upper surface of the machined part. Then, according to the size of the machined part, the position of the clamping block is adjusted so that the clamping block can clamp the workpiece at an appropriate position. The clamping cylinder is activated, which pushes the clamping plate inward, thereby clamping and fixing the machined part. Next, grinding and leveling are performed. The lifting cylinder and the dual-axis motor are activated. The lifting cylinder pushes the lifting plate downward along the guide column. The lifting plate drives the dual-axis motor to move downward, so that the grinding wheel begins to contact the upper surface of the workpiece. The dual-axis motor drives the gear and the grinding wheel to rotate, and the grinding wheel rotates to grind the machined part.

[0003] The patent document states that when clamping a workpiece, it can only clamp and fix regular workpieces. However, when flattening the end face of some irregularly shaped workpieces, the existing clamping structure obviously cannot clamp and fix them quickly and stably. Utility Model Content

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1-9 As shown, a leveling processing device for machined parts includes a leveling mechanism 3 and a fixing mechanism 1, which is provided with four clamping mechanisms 2.

[0032] In this embodiment: the fixing mechanism 1 includes a base 11, which has a communicating cavity 18 and two liquid storage cavities 17 inside. The two liquid storage cavities 17 are located on both sides of the communicating cavity 18 and are interconnected. The base 11 has multiple piston holes 15 communicating with the communicating cavity 18. Each piston hole 15 has a support column 14 extending out of the base 11 slidably connected to it. A sliding plate 12 is slidably connected to the top of the communicating cavity 18. The top of the sliding plate 12 has through holes corresponding to the multiple piston holes 15. The front side of the base 11 is provided with a driving assembly for moving the sliding plate 12 back and forth. Four guide grooves 16 are provided at the diagonal position of the top of the base 11. The end of the support column 14 extending out of the base 11 has a ball head. The end of the support column 14 located in the piston hole 15 has a piston ring. The top two sides of the seat 11 are provided with slots for adding liquid into the liquid storage chamber 17. The irregular workpiece to be processed is placed on the upper end of multiple support columns 14. The ball head at the upper end of the support column 14 supports the irregular surface of the workpiece. The weight of the workpiece pushes the multiple support columns 14 into the corresponding piston holes 15. Then, the multiple support columns 14 will retract into the piston holes 15 to varying degrees. After the irregular workpiece is placed with the processed surface facing upward and stable, the sliding plate 12 slides forward and drives its through hole to be misaligned with the corresponding piston hole 15, thereby sealing the liquid in the piston hole 15. At this time, it can be ensured that the liquid in the multiple piston holes 15 does not flow with each other, and the multiple support columns 14 can support the irregular workpiece in this state.

[0033] In this embodiment: the clamping mechanism 2 includes a lead screw 25, a clamping frame 22 is threadedly connected to the outer side of the lead screw 25, a lifting seat 23 is slidably connected to one side of the clamping frame 22, a push spring 24 is fixedly fixed to the bottom of the lifting seat 23, a clamping motor 21 is fixedly installed at the input end of the lead screw 25, a groove is opened on the side of the clamping frame 22 near the workpiece for the lifting seat 23 to slide up and down, and the lower end of the push spring 24 is fixedly connected to the bottom of the groove, the lead screw 25 is rotatably connected in the guide groove 16 of the base 11, clamping... The frame 22 is slidably connected to the guide slide 16. The rotating part of the clamping motor 21 drives the lead screw 25 to rotate, so that the clamping frame 22 on the outside of the lead screw 25 drives the lifting seat 23 to move closer to the irregular workpiece. At the same time, the lifting seat 23 can be pressed down to move it down along the clamping frame 22, so as to prevent the upper end of the lifting seat 23 from exceeding the surface of the workpiece that needs to be leveled. Then, the four clamping frames 22 drive the corresponding lifting seats 23 to clamp and fix the side of the irregular workpiece, so as to prevent shaking during the leveling process.

[0034] In this embodiment: the driving component includes an electromagnetic block 13, which is fixed to the front side of the base 11. A magnetic block corresponding to the electromagnetic block 13 is fixed to one end of the sliding plate 12 that extends out of the base 11. When the electromagnetic block 13 is energized, it repels the magnetic block on the front side of the sliding plate 12, thereby causing the magnetic block to drive the sliding plate 12 to move forward. When the electromagnetic block 13 is de-energized, the magnetic block attracts the electromagnetic block 13, causing the sliding plate 12 to move backward, so that the through hole on the sliding plate 12 corresponds to the piston hole 15, thereby allowing multiple piston holes 15 to connect with the connecting cavity 18, and then quickly bringing multiple support columns 14 to the same horizontal plane.

[0035] In this embodiment: the leveling mechanism 3 includes two horizontal frames 31 arranged front and rear. The lower ends of the two horizontal frames 31 are fixed to the front and rear sides of the base 11 respectively. A movable seat 32 is slidably connected to the top of the horizontal frame 31. An adjusting seat 33 is slidably connected to the top of the movable seat 32. The sliding directions of the adjusting seat 33 and the movable seat 32 are perpendicular to each other. A leveling motor 34 is fixedly installed on the top of the adjusting seat 33. A leveling grinding wheel 35 is fixed at the output end of the leveling motor 34 and is located below the adjusting seat 33. The movable seat 32 drives the adjusting seat 33 to move along the top of the horizontal frame 31 to both sides. The adjusting seat 33 drives the leveling motor 34 and the leveling grinding wheel 35 to move back and forth to both sides. Then the leveling motor 34 drives the leveling grinding wheel 35 to rotate to perform leveling and grinding processing on the workpiece.

[0036] Working principle: In use, the irregular workpiece to be processed is first placed on the upper end of multiple support columns 14, and the ball head at the upper end of the support column 14 abuts against the bottom of the irregular surface of the workpiece. The weight of the workpiece is used to press the multiple support columns 14 downward into the corresponding piston holes 15. During this process, as the support column 14 moves downward, the liquid on its lower side will flow into the connecting cavity 18 through the through hole of the sliding plate 12, and the liquid in the connecting cavity 18 will also continuously flow into the liquid storage cavity 17.

[0037] After the irregular workpiece is placed with the machined surface facing up and stable, the electromagnetic block 13 is energized to repel the magnetic block on the front side of the sliding plate 12. The magnetic block drives the sliding plate 12 to move forward. At this time, the through hole on the sliding plate 12 is misaligned with the corresponding piston hole 15, thereby blocking the liquid in the piston hole 15 and preventing the liquid in the multiple piston holes 15 from not flowing together. This ensures that the multiple support columns 14 support the irregular workpiece in this state.

[0038] At the same time, the clamping motors 21 at the four diagonal positions of the base 11 start simultaneously. The rotating part of the clamping motor 21 drives the lead screw 25 to rotate, so that the clamping frame 22 on the outside of the lead screw 25 drives the lifting seat 23 to move closer to the irregular workpiece. At the same time, the lifting seat 23 can be pressed down to move it down along the clamping frame 22, so as to prevent the upper end of the lifting seat 23 from exceeding the surface of the workpiece that needs to be leveled. Then, the four clamping frames 22 drive the corresponding lifting seats 23 to clamp and fix the side of the irregular workpiece, so as to prevent shaking during the leveling process. During this process, the elastic force of the push spring 24 is small, and it can only lift the lifting seat 23 upward, so it is not enough to push the irregular workpiece upward.

[0039] Then, the movable seat 32 drives the adjusting seat 33 to move along the top of the horizontal frame 31 to both sides. The adjusting seat 33 drives the leveling motor 34 and the leveling grinding wheel 35 to move back and forth to both sides. Then, the leveling motor 34 drives the leveling grinding wheel 35 to rotate to perform leveling and grinding on the workpiece.

[0040] After the irregular workpiece is flattened, the lead screw 25 rotates in the opposite direction to drive the clamping frame 22 and the lifting seat 23 to move away from the workpiece, thereby detaching from the clamping of the irregular workpiece and removing the irregular workpiece from the multiple support columns 14. Then, the electromagnetic block 13 is de-energized, and the magnetic attraction between the magnetic block and the electromagnetic block 13 causes the sliding plate 12 to move backward, so that the through hole on the sliding plate 12 corresponds to the piston hole 15, thereby allowing multiple piston holes 15 to connect with the connecting cavity 18, and then quickly bringing multiple support columns 14 to the same horizontal plane.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
