Description

Technical Field

[0001] The present invention relates to the technical field of fixture production equipment, and specifically relates to a fixture processing device for automobile stamping parts. Background Art

[0002] Automobile stamping parts are metal stamping parts that make up automobile components. Among automobile stamping parts, some directly become automobile components after stamping, and some need to go through processes such as welding, machining, or painting after stamping before becoming automobile components. Among automobile stamping parts, the most processed ones are stamping pipe fittings. The stability of pipe fitting clamping is crucial for pipe fitting processing. Most of the clamping blocks used for pipe fitting clamping are matched with the outer shape of the pipe fitting. The clamping blocks are provided with semi-circular concave surfaces with the same radius as the pipe fitting. After the clamping blocks are formed, their surfaces need to be polished to ensure that there are no burrs on the surfaces and prevent the burrs from scratching the pipe fittings.

[0003] Currently, when grinding and polishing the clamping blocks of automobile pipe fittings, most are manually polished using grinding tools. The efficiency of manual grinding is low, and when workers work in the grinding environment for a long time, it is easy to inhale the debris during grinding into the body, causing harm to the bodies of the grinding workers. Summary of the Invention

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a fixture processing device for automobile stamping parts, including a U-shaped frame. A U-shaped plate is fixedly installed on the U-shaped frame. A top frame is fixedly installed at the top of the U-shaped frame. A conical hollow cylinder is fixedly installed through the bottom of the U-shaped frame. It further includes: A protection mechanism, the protection mechanism includes a water pump, a limiting component, the water pump is used for limiting the limiting component, and a protection component, the water pump is used for protecting the protection component; The limiting component includes a hydraulic cylinder fixedly installed through the top frame. The output end of the hydraulic cylinder is fixedly installed with a hollow plate. A plurality of arc-shaped hollow blocks are fixedly installed at the bottom of the hollow plate.

A circular hollow box is fixedly installed on the conical hollow cylinder, and the water suction pipe communicates with the circular hollow box.

[0006] Start the hydraulic cylinder. The hydraulic cylinder drives the hollow plate to descend, and the hollow plate drives a number of arc-shaped hollow blocks to descend synchronously and contact the arc-shaped clamping blocks.

[0007] Furthermore, a hollow shaft is rotatably installed at the bottom of the C-shaped plate.

[0008] Start the driving motor. The driving motor drives the hollow shaft to rotate. The hollow shaft drives a number of stirring blades to rotate. The stirring blades drive the water in the conical hollow cylinder to rotate. Under the action of centrifugal force, since the density of the particles is greater than that of water, the impurity particles will move away from the hollow shaft. The particles will quickly leave along the inclined surface of the conical hollow cylinder and precipitate, leaving the clean water above the impurities.

[0009] Furthermore, a number of water inlet holes are opened on the outer wall of the hollow shaft, and a number of water outlet holes are opened on the hollow shaft. A number of the water outlet holes are distributed in the circular hollow box, and a number of the water inlet holes are distributed in the conical hollow cylinder.

[0010] When in use, start the water pump. The water pump sucks water into the circular hollow box through the water suction pipe. The circular hollow box sucks water from the conical hollow cylinder through the water outlet holes and the water inlet holes on the hollow shaft, and the water flows into the hollow plate from the water outlet pipe.

[0011] Furthermore, two water inlet boxes are fixedly installed at the bottom of the C-shaped plate. Both of the two water inlet boxes communicate with the C-shaped plate. Two water inlet pipes are respectively fixedly installed at the bottoms of the two water inlet boxes. The bottoms of the two water inlet pipes communicate with the conical hollow cylinder.

[0012] The water will carry the impurity particles and flow into the water inlet box, and then enter the conical hollow cylinder again along the water inlet box and the water inlet pipe.

[0013] Furthermore, a number of limiting mechanisms are arranged in the C-shaped frame. The limiting mechanism includes two strip-shaped grooves opened on the inner wall of the C-shaped frame. Limiting springs are respectively fixedly installed on the right inner walls of the two strip-shaped grooves. A rectangular plate is fixedly installed at the left ends of the two limiting springs. The rectangular plate is slidably connected to the two strip-shaped grooves.

[0014] When the movable plate rises, the limiting spring will push the rectangular plate to reset under the action of elastic force, laying a foundation for the next step of the movable plate to fit with the limiting groove.

[0015] Further, the limiting mechanism further includes a movable plate hinged to the bottom of the hollow plate. A limiting groove is formed at the top of the rectangular plate, and the rectangular plate is adapted to the limiting groove.

[0016] During the descent of the hollow plate, the movable plate will be driven to descend. During the descent of the movable plate, it will enter the limiting groove. As the hollow plate continues to descend.

A telescopic spring is sleeved on the T-shaped rectangular rod. An arc-shaped plate one is slidably sleeved on the T-shaped rectangular rod. The bottom end of the telescopic spring is fixedly connected to the C-shaped plate, and the top end of the telescopic spring is fixedly connected to the arc-shaped plate one.

[0018] The movable plate will tilt towards the direction close to the arc-shaped clamping block under the action of the inclined surface of the limiting groove. The movable plate will be stuck in the limiting groove and push the rectangular plate to move towards the direction close to the arc-shaped clamping block.

[0019] Further, the limiting mechanism further includes two cylinders fixedly installed on the left side of the arc-shaped plate one. An arc-shaped plate two is arranged on the left side of the arc-shaped clamping block. Two C-shaped rods are fixedly installed on the left side of the arc-shaped plate two. The ends of the two C-shaped rods respectively extend into the two cylinders and are respectively slidably connected to the two cylinders. Abrasive cloths are respectively arranged on the mutually close surfaces of the arc-shaped plate two and the arc-shaped plate one.

[0020] The arc-shaped plate two will contact the arc-shaped clamping block and clamp the arc-shaped clamping block through the arc-shaped plate one, so as to ensure the full contact between the abrasive cloth and the arc-shaped clamping block and improve the fineness of grinding.

[0021] Further, grinding mechanisms are respectively arranged on several of the rectangular plates. The grinding mechanism includes two L-shaped round rods fixedly installed at the bottom of the rectangular plate. Both of the two L-shaped round rods slidably penetrate through the arc-shaped plate two. A T-shaped support plate is fixedly installed on the arc-shaped plate two. A rectangular sliding rod is fixedly installed in the T-shaped support plate. A special-shaped plate is slidably sleeved on the rectangular sliding rod. The end of the special-shaped plate passes through the C-shaped frame and extends below the C-shaped plate.

[0022] Under the action of the inclined surface of the special-shaped plate, the special-shaped plate will rise. The special-shaped plate will drive the rectangular sliding rod to rise. The rectangular sliding rod will drive the T-shaped support plate to rise. The T-shaped support plate will drive the arc-shaped plate two to rise.

[0023] Further, two transmission rods are rotatably installed at the bottom of the C-shaped plate. The bottom ends of the two transmission rods extend outside the C-shaped frame and are rotatably connected to the C-shaped frame. Transmission wheels are fixedly sleeved on the hollow shaft and the two transmission rods respectively. A transmission belt is sleeved on several of the transmission wheels. Discs are fixedly sleeved on the hollow shaft and the two transmission rods respectively. Contact plates are fixedly installed on several of the discs.

[0024] During the rotation of the hollow shaft, it will drive the transmission wheels and the transmission belt to rotate.

The transmission rods and the hollow shaft will drive several discs to rotate. The discs will drive the contact plates to rotate. During the rotation of the contact plates, they will come into contact with the special-shaped plate.

[0025] The present invention has the following beneficial effects: (1) For the fixture processing device for automobile stamping parts of the present invention, when in use, start the water pump. The water pump sucks water into the circular hollow box through the suction pipe. The circular hollow box sucks water from the conical hollow cylinder through the water outlet holes and the water inlet holes on the hollow shaft. The water flows into the hollow plate from the water outlet pipe, and then the water enters into several arc-shaped hollow blocks. The water entering the arc-shaped hollow blocks will be discharged from the arc-shaped grooves. The water will slowly flow down along the arc-shaped clamping blocks. During the grinding process, the water can effectively avoid the generation of smoke and dust, prevent harmful particles in the smoke and dust from being inhaled by the human body and affecting physical health. When the water flows through the arc-shaped clamping blocks and the sand cloth, it can prevent the arc-shaped clamping blocks and the sand cloth from being burned out due to high temperature generated by too fast grinding speed, ensuring the safe and stable progress of the grinding work. The water flowing through the arc-shaped clamping blocks flows back into the C-shaped plate. The water will carry impurity particles and flow into the water inlet box, and then enter the conical hollow cylinder again along the water inlet box and the water inlet pipe. Start the driving motor. The driving motor drives the hollow shaft to rotate. The hollow shaft drives several stirring blades to rotate. The stirring blades drive the water in the conical hollow cylinder to rotate. Under the action of the centrifugal force, since the density of the particles is greater than that of the water, the impurity particles will move away from the hollow shaft. The particles will quickly leave along the inclined surface of the conical hollow cylinder and precipitate, leaving the clean water above the impurities, ensuring that the water is clean during the water pumping process by the water pump and ensuring the effective recycling of the water. (2) For a fixture processing device for automotive stamping parts according to the present invention, when the hydraulic cylinder is started, the hollow plate is driven by the hydraulic cylinder to descend. The hollow plate drives a number of arc-shaped hollow blocks to descend synchronously and contact the arc-shaped clamping blocks. At this time, the arc-shaped cushion blocks and the arc-shaped hollow blocks clamp the arc-shaped clamping blocks. During the descent of the hollow plate, the movable plate will be driven to descend. During the descent of the movable plate, it will enter the limit groove. As the hollow plate continues to descend, the movable plate will tilt towards the direction close to the arc-shaped clamping block under the action of the inclined surface of the limit groove. The movable plate will be stuck in the limit groove and push the rectangular plate to move towards the direction close to the arc-shaped clamping block. At this time, the limit spring undergoes compressive deformation. When the movable plate rises, the limit spring will push the rectangular plate to reset under the action of the elastic force, laying the foundation for the next fit between the movable plate and the limit groove. The movement of the rectangular plate will drive the L-shaped round rod to move, and the L-shaped round rod will drive the second arc-shaped plate to move. The second arc-shaped plate will contact the arc-shaped clamping block and clamp the arc-shaped clamping block through the first arc-shaped plate, thereby ensuring full contact between the sandpaper and the arc-shaped clamping block and improving the fineness of grinding. (3) For a fixture processing device for automotive stamping parts according to the present invention, during the movement of the second arc-shaped plate, the U-shaped rod will be driven to move synchronously. The U-shaped rod will slide into the cylinder. Under the limiting action of the U-shaped rod and the cylinder, the first arc-shaped plate and the second arc-shaped plate will be in a stable state and will not slide. When the second arc-shaped plate moves, the special-shaped plate will slide on the rectangular sliding rod, thereby ensuring the stability of the special-shaped plate during grinding. During the rotation of the hollow shaft, the transmission wheel and the transmission belt will be driven to rotate. Under the action of the transmission wheel and the transmission belt, two transmission rods will be driven to rotate synchronously. The transmission rods and the hollow shaft will drive a number of discs to rotate. The discs will drive the contact plate to rotate. During the rotation of the contact plate, it will contact the special-shaped plate. Under the action of the inclined surface of the special-shaped plate, the special-shaped plate will rise. The special-shaped plate will drive the rectangular sliding rod to rise, and the rectangular sliding rod will drive the T-shaped support plate to rise. The T-shaped support plate will drive the second arc-shaped plate to rise. Under the action of the U-shaped rod and the cylinder, the second arc-shaped plate will drive the first arc-shaped plate to rise synchronously. The sandpaper on the first arc-shaped plate and the second arc-shaped plate will grind the arc-shaped clamping block. After the contact plate leaves the special-shaped plate, the second arc-shaped plate and the first arc-shaped plate will descend. During the continuous reciprocating movement, the sandpaper will continuously and comprehensively grind the arc-shaped clamping block, thereby improving the grinding efficiency.

[0026] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] As Figure 8 As shown, grinding mechanisms 7 are respectively arranged on several rectangular plates 604. The grinding mechanism 7 includes two L-shaped round rods 701 fixedly installed at the bottom of the rectangular plate 604. The two L-shaped round rods 701 both slidably penetrate through the arc-shaped plate two 612. A T-shaped support plate 702 is fixedly installed on the arc-shaped plate two 612.

During the rotation, the contact plates 709 will come into contact with the special-shaped plate 704.

[0050] During use, start the water pump 505. The water pump 505 sucks water into the circular hollow box 508 through the suction pipe 507. The circular hollow box 508 sucks water from the conical hollow cylinder 4 through the water outlet hole 513 and the water outlet hole 513 through the water inlet hole 512 on the hollow shaft 509. The water flows from the water outlet pipe 506 into the hollow plate 502, and then enters several arc-shaped hollow blocks 503. The water entering the arc-shaped hollow blocks 503 will be discharged from the arc-shaped groove 504. The water will slowly flow down along the arc-shaped clamping block 607. During the grinding process, the water can effectively avoid the generation of dust and prevent harmful particles in the dust from being inhaled by the human body and affecting physical health. When the water flows through the arc-shaped clamping block 607 and the sandcloth 614, it can prevent the arc-shaped clamping block 607 and the sandcloth 614 from being burned out due to the high temperature generated by the too fast grinding speed, ensuring the safe and stable progress of the grinding work.

Start the driving motor 510. The driving motor 510 drives the hollow shaft 509 to rotate. The hollow shaft 509 will drive several stirring blades 511 to rotate. The stirring blades 511 will drive the water in the conical hollow cylinder 4 to rotate. Under the action of centrifugal force, since the density of the particles is greater than that of the water, the impurity particles will move away from the hollow shaft 509. The particles will quickly leave and precipitate along the inclined surface of the conical hollow cylinder 4, leaving the clean water above the impurities, ensuring that the water is clean during the pumping process of the water pump 505 and ensuring the effective recycling of the water; Start the hydraulic cylinder 501. The hydraulic cylinder 501 drives the hollow plate 502 to descend. The hollow plate 502 drives several arc-shaped hollow blocks 503 to descend synchronously and contact the arc-shaped clamping block 607. At this time, the arc-shaped cushion block 606 and the arc-shaped hollow block 503 clamp the arc-shaped clamping block 607. During the descent of the hollow plate 502, it will drive the movable plate 601 to descend. The movable plate 601 will enter the limit groove 605 during the descent. As the hollow plate 502 continues to descend, the movable plate 601 will tilt towards the arc-shaped clamping block 607 under the action of the inclined surface of the limit groove 605. The movable plate 601 will be stuck in the limit groove 605 and push the rectangular plate 604 to move towards the arc-shaped clamping block 607. At this time, the limit spring 603 undergoes a compressive deformation. When the movable plate 601 rises, the limit spring 603 will push the rectangular plate 604 to reset under the action of the elastic force, laying the foundation for the next fit between the movable plate 601 and the limit groove 605. The movement of the rectangular plate 604 will drive the L-shaped round rod 701 to move. The L-shaped round rod 701 will drive the second arc-shaped plate 612 to move. The second arc-shaped plate 612 will contact the arc-shaped clamping block 607 and clamp the arc-shaped clamping block 607 through the first arc-shaped plate 610, thereby ensuring the full contact between the sandcloth 614 and the arc-shaped clamping block 607 and improving the fineness of grinding; During the movement of the second arc-shaped plate 612, it will drive the C-shaped rod 613 to move synchronously. The C-shaped rod 613 will slide into the cylinder 611. Under the limiting action of the C-shaped rod 613 and the cylinder 611, the first arc-shaped plate 610 and the second arc-shaped plate 612 will be in a stable state and will not slide. When the second arc-shaped plate 612 moves, the special-shaped plate 704 will slide on the rectangular slide rod 703, thus ensuring the stability of the special-shaped plate 704 during grinding. During the rotation of the hollow shaft 509, it will drive the transmission wheel 706 and the transmission belt 707 to rotate. Under the action of the transmission wheel 706 and the transmission belt 707, two transmission rods 705 will be driven to rotate synchronously. The transmission rods 705 and the hollow shaft 509 will drive a number of discs 708 to rotate. The discs 708 will drive the contact plate 709 to rotate. During the rotation of the contact plate 709, it will contact the special-shaped plate 704. Under the action of the inclined surface of the special-shaped plate 704, the special-shaped plate 704 will rise. The special-shaped plate 704 will drive the rectangular slide rod 703 to rise. The rectangular slide rod 703 will drive the T-shaped support plate 702 to rise. The T-shaped support plate 702 will drive the second arc-shaped plate 612 to rise. The second arc-shaped plate 612 will drive the first arc-shaped plate 610 to rise synchronously under the action of the C-shaped rod 613 and the cylinder 611. The abrasive cloth 614 on the first arc-shaped plate 610 and the second arc-shaped plate 612 will grind the arc-shaped clamping block 607. After the contact plate 709 leaves the special-shaped plate 704, the second arc-shaped plate 612 and the first arc-shaped plate 610 will descend. During the continuous reciprocating movement, the abrasive cloth 614 will continuously and comprehensively grind the arc-shaped clamping block 607, thereby improving the grinding efficiency.
