Description

Technical Field

[0001] The present invention relates to a spinning forming device for a workpiece surface groove processing device, which is mainly used for spinning forming processing of the surface grooves of a workpiece during rotation. Background Art

[0002] Existing workpieces, such as pulley wheels, etc., often need to be processed with grooves on the surface of the workpiece blank through corresponding workpiece surface groove processing devices. Existing workpiece surface groove processing devices generally include a workpiece rotation driving device for rotationally driving a blank workpiece, and a spinning forming device for spinning and processing grooves on the surface of the workpiece.

[0003] The existing spinning forming device for a workpiece surface groove processing device mainly includes a fixed seat driven by a corresponding moving driving mechanism, and a spinning mechanism installed on the fixed seat. The spinning mechanism generally includes a spinning wheel, and the spinning wheel is rotationally installed on the fixed seat through a corresponding connecting member. During the processing, the fixed seat and the spinning wheel are driven in place by the moving driving mechanism, so that the spinning wheel contacts the surface of the workpiece, thereby performing surface groove processing on the surface of the workpiece during rotation. During the process of the spinning wheel performing spinning processing on the surface of the workpiece, a certain degree of temperature rise is likely to occur. Since the amount of temperature rise is relatively small compared to the temperature rise of other machining processes, therefore, some spinning forming devices do not directly provide a cooling system, resulting in a small amount of deformation of the spinning wheel after the temperature rise, thus affecting the processing accuracy; while for some spinning forming processes with relatively high processing accuracy requirements, a direct spraying method of coolant is used to cool the contact position between the spinning wheel and the workpiece, which consumes a large amount of coolant. In addition, a coolant recovery and recycling system needs to be provided, resulting in relatively high processing costs.

[0004] Therefore, the research objective of the present invention is to design a spinning forming device for a workpiece surface groove processing device that can achieve uniform cooling and temperature reduction treatment of the spinning wheel on the premise of low-cost investment, thereby effectively maintaining the spinning processing accuracy of the spinning wheel for the workpiece. Summary of the Invention

[0006] The technical solution of the present invention is as follows:

A corresponding fan is fixedly installed on the upper part of the coolant container, and the driving shaft of the fan is drivingly connected to the connecting shaft;

[0012] The cooling atomized liquid ejection mechanism includes a plurality of arc-shaped blade plates rotatably arranged in the installation groove on the inner side of the partition plate; when the spinning wheel rotates, the plurality of arc-shaped blade plates rotate to eject the cooling atomized liquid in the installation groove to cool the spinning wheel.

The rotating wheels are rotatably installed on the connecting piece through corresponding fixed shafts; the driving shaft of the fan is drivingly connected to the fixed shaft through a belt drive mode, and the fixed shaft is drivingly connected to the connecting shaft through a belt drive mode.

[0014] During the rotation of the spinning wheel, the connecting shaft drives the fixed shaft and the driving shaft to rotate respectively, so as to drive the fan to rotate to inject the atomized coolant into the installation groove along the conduit, and at the same time drive the arc-shaped blade plates to rotate, so as to eject the cooling atomized liquid in the installation groove to cool the spinning wheel.

[0015] A group of sealing plates located on the upper and lower sides of the guide hole are fixedly connected to the inner side of the partition plate according to height. Corresponding magnets are fixedly connected to both sides of the sealing plate. The rotating wheel is rotatably installed on the fixed shaft through a corresponding one-way bearing. Along the rotatable direction of the one-way bearing, magnetic metal pieces corresponding to the magnets are fixedly connected to the front side of the outer end of the arc-shaped blade plate, and the end spacing between two or more adjacent arc-shaped blade plates is equal to the spacing between the two magnets.

[0016] When the spinning wheel stops rotating, under the action of the magnetic attraction force between the magnetic metal part and the magnet, the magnetic metal part that is close to and faces the magnet is adsorbed and connected to the magnet, so that the arc-shaped blade plate and the sealing plate cooperate to form a closure for the guide hole on the partition plate.

[0017] The belt transmission ratio between the connecting shaft and the fixed shaft, and the transmission ratio between the fixed shaft and the driving shaft of the fan are both greater than 2.

[0021] The ultrasonic atomization sheet is connected to an external power supply through a corresponding electric controller.

[0022] Advantages of the present invention:

[0023] 1) The top of the connecting part of the present invention is horizontally arranged, so that the coolant container of the coolant atomization mechanism can be fixedly installed on the top of the connecting part; by adding a cooling atomized liquid circulation mechanism, during the rotation of the spinning wheel, the atomized coolant can be synchronously blown into the installation groove inside the partition plate; and then by adding a cooling atomized liquid pushing mechanism, during the rotation of the spinning wheel, the atomized coolant can be continuously pushed out of the guide hole of the partition plate, so that it directly and evenly adheres to the spinning wheel during rotation, thereby realizing uniform cooling of the spinning wheel, realizing uniform cooling and temperature reduction treatment of the spinning wheel on the premise of low-cost investment, and effectively maintaining the spinning processing accuracy of the spinning wheel for workpieces.

[0024] 2) Several arc-shaped blade plates of the present invention are respectively fixedly connected to the corresponding rotating wheels at equal intervals. The rotating wheels are rotationally installed on the connecting member through the corresponding fixed shafts; the driving shaft of the fan is drivingly connected to the fixed shaft by a belt drive method, and the fixed shaft is drivingly connected to the connecting shaft by a belt drive method. The driving power source of several arc-shaped blade plates and the fan directly uses the spinning wheel itself, so that during the rotation of the spinning wheel, that is, during the processing of the spinning wheel, the atomized coolant can be synchronously output to cool the spinning wheel. It can not only reduce the consumption of the coolant and the energy consumption required for driving the arc-shaped blade plates and the fan, but also prevent the continuous output of the coolant to the non-rotating spinning wheel, so as to prevent the overall temperature of the spinning wheel from being uneven, thereby ensuring the practical effect of the present invention.

[0025] 3) A group of sealing plates are fixedly connected to the inner side of the partition of the present invention according to height. Magnets are respectively fixedly connected to both sides of the sealing plates. The rotating wheels are rotationally installed on the fixed shafts through the corresponding one-way bearings. Along the rotatable direction of the one-way bearings, magnetic metal parts corresponding to the magnets are respectively fixedly connected to the front side surfaces of the outer ends of the arc-shaped blade plates. The end spacing between two or more adjacent arc-shaped blade plates is equal to the spacing between the two magnets. When the spinning wheel stops rotating, under the action of the magnetic attraction between the magnetic metal parts and the magnets, the magnetic metal parts close to and facing the magnets are adsorbed and connected to the magnets, so that the arc-shaped blade plates and the sealing plates cooperate to form a seal for the guide holes on the partition. To further ensure that when the spinning wheel is not rotating, the atomized coolant is not output, thereby further ensuring the overall temperature uniformity of the spinning wheel and further ensuring the practical effect of the present invention.

[0026] 4) The belt drive ratio between the connecting shaft and the fixed shaft of the present invention, and the drive ratio between the fixed shaft and the driving shaft of the fan are both greater than 2, so as to gradually increase the rotational speeds of the arc-shaped blade plates and the fan, thereby effectively maintaining the rotational speeds of the arc-shaped blade plates and the fan at a relatively high level, so as to further ensure the practical effect of the present invention.

[0038] The cooling atomized liquid ejection mechanism 305 includes a plurality of arc-shaped blade plates 3051 rotatably arranged in the installation groove 3011 inside the partition plate 4.

Through the addition of the cooling atomized liquid circulation mechanism 304, during the rotation of the spinning wheel 302, the atomized coolant is synchronously blown into the installation groove 3011 inside the partition plate 4.

The end spacing between three adjacent arc-shaped blade plates 3051 is equal to the spacing between two of the magnets 7.

[0044] When the spinning wheel 302 stops rotating, under the action of the magnetic attraction force between the magnetic metal part 9 and the magnet 7, the magnetic metal part 9 close to and facing the magnet 7 is adsorbed and connected to the magnet 7, so that the arc-shaped blade plate 3051 and the sealing plate 6 cooperate to form a closure for the guide holes on the partition plate 4. To further ensure that when the spinning wheel is not rotating, the atomized coolant is not output, thereby further ensuring the overall temperature uniformity of the spinning wheel, and further ensuring the practical effect of the present invention.

[0045] The belt transmission ratio between the connecting shaft 3021 and the fixed shaft 3053, and the transmission ratio between the fixed shaft 3053 and the drive shaft 5 of the fan 3042 are both greater than 2. To gradually increase the rotation speeds of the arc-shaped blade plate 3051 and the fan 3042, so as to effectively maintain the rotation speeds of the arc-shaped blade plate 3051 and the fan 3042 at a relatively high level, and further ensure the practical effect of the present invention.
