Description

Technical Field

[0001] The invention relates to a workpiece surface groove processing device, which can stably drive the workpiece to rotate, and can perform high-precision surface groove spinning processing on the workpiece in the rotating process. Background Art

[0002] Existing workpieces, such as pulleys, often need to be grooved on the surface of the workpiece blank by corresponding workpiece surface groove processing equipment. The existing workpiece surface groove processing equipment generally includes a workpiece rotation driving device for rotating the blank workpiece and a spinning forming device for spinning the groove on the surface of the workpiece.

[0003] At present, the workpiece rotation drive device used in workpiece surface groove processing equipment mostly includes a rotating base rotatably mounted on the bottom side of the frame, and a lifting seat that can be lifted and lowered on the upper side of the frame. The lifting seat is driven downward by a lifting cylinder to rotatably clamp the rough workpiece between the lifting seat and the rotating base, and then the rotating base and the lifting seat are driven to rotate by a corresponding driving mechanism. Since the middle part of the rough workpiece is mostly provided with a mounting hole, during the longitudinal clamping process, if the clamping force is low, the rough workpiece will easily be positionally offset during the spinning process; if the clamping force is high, it is easy to cause mechanical damage to the upper and lower ends of the rough workpiece.

[0004] The spinning wheel of the existing spin forming device for workpiece surface groove processing equipment is prone to a certain degree of temperature rise during the spinning process. Since the temperature rise is relatively small compared with the temperature rise of other machining, some spin forming devices do not directly set up a cooling system, which causes the spinning wheel to easily form a small amount of deformation after heating, thereby affecting the processing accuracy; while some spin forming devices use a direct spraying method of coolant to cool the contact position between the spinning wheel and the workpiece, which consumes a large amount of coolant. In addition, a coolant recovery circulation system needs to be set up. Therefore, the overall processing cost is relatively high.

[0005] Therefore, the purpose of the present invention is to design a workpiece surface groove processing equipment that can not only fix the upper and lower ends of the workpiece, but also form a complete round tube support surface at the mounting hole of the workpiece, so as to effectively ensure the overall clamping effect of the workpiece and reduce the deformation of the workpiece mounting hole caused by the spinning process; and can achieve uniform cooling and temperature reduction treatment of the spinning wheel under the premise of low cost investment, so as to effectively maintain the spinning processing accuracy of the spinning wheel on the workpiece.

[0011] A coolant adding port is arranged on the top of the coolant container, a corresponding sealing cover is detachably mounted on the coolant adding port, and a condensate discharge hole is arranged on the bottom side of the connecting piece.

[0012] The mobile driving mechanism includes a workbench and a mobile seat installed on the workbench in a transversely movable manner. The fixed seats can be installed on the mobile seat in a lifting manner respectively. The mobile seat is driven by a horizontal cylinder fixedly installed on the workbench, and the fixed seat is driven by a lifting cylinder fixedly installed on the mobile seat.

[0013] The two sides of the arc-shaped push-blocking plate are respectively provided with corresponding abutting inclined surfaces inclined inwardly, and the two sides of the arc-shaped tightening plate are respectively provided with tightening inclined surfaces adapted to the abutting inclined surfaces.

[0014] The arc-shaped push plate, the arc-shaped top clamping plate, and the bottom of the push shaft respectively extend to the lower side of the bottom end portion of the fixed cylinder body, and a plurality of fixed blocks located on the inner side of the arc-shaped top clamping plate are arranged at intervals on the rotating base, and corresponding swing rods are respectively swingably mounted on the fixed blocks. When the lifting seat moves down into position to fix the workpiece between the lifting seat and the rotating base, the bottom end portion of the fixed cylinder body presses down on the inner end portion of the swing rod, so that the outer end portion of the swing rod is fixedly pressed against the bottom side of the inner side wall of the arc-shaped top clamping plate, and the outer end portion of the swing rod is respectively fixedly connected with an arc rod member abutting against the lower side of the arc-shaped top clamping plate.

[0015] The top ends of the arc-shaped push plate and the arc-shaped top clamping plate are respectively in an inverted L-shape and fixedly connected outwardly with corresponding buffer pressure plates, and the buffer pressure plates are made of rubber material; the middle part of the lifting seat is integrally formed with a mounting truncated table for connecting the fixed cylinder body, and the outer edge of the mounting truncated table is located on the outer side of the fixed cylinder body. The lifting seat is pressed downward on the upper side of the buffer pressure plate, so that the buffer pressure plate is fixed between the lifting seat and the top end of the workpiece in an extruded state, and the outer edge of the mounting truncated table forms a travel limit for the inner side of the buffer pressure plate after extrusion and deformation.

[0016] A circle of corresponding guide protrusions is arranged inwardly on the bottom side of the fixed cylinder, and the push shaft can be movably inserted in the guide protrusions, and the upper side of the push shaft is arranged at a distance from the fixed cylinder; the middle part of the rotating base is integrally formed with a push round table for pushing the push shaft upward, and the fixed blocks are respectively arranged on the rotating base outside the push round table.

[0017] Advantages of the present invention: 1) The present invention is provided with a covering inner hole limit assembly. Under the drive of the inverted T-shaped grooves of different inclination angles of the limit drive mechanism, the arc-shaped push plate and the arc-shaped top clamping plate can be pushed outward at the same time, and the moving speed of the arc-shaped top clamping plate is greater than that of the arc-shaped push plate, so that when the lifting seat moves down to the position to clamp the workpiece between the lifting seat and the rotating base, the arc-shaped push plate and the arc-shaped top clamping plate are pushed outward to the position synchronously, so that the arc-shaped push plate and the arc-shaped top clamping plate form a complete round tube support surface at the installation hole of the workpiece. It can not only fix the upper and lower ends of the workpiece, but also form a complete round tube support surface at the installation hole of the workpiece, thereby effectively ensuring the overall clamping effect of the workpiece, and reducing the deformation of the workpiece installation hole caused by the spinning process.

[0018] 2) The two sides of the arc-shaped push-block plate of the present invention are respectively inclined inwardly to be provided with corresponding abutting inclined surfaces, and the two sides of the arc-shaped top clamping plate are respectively provided with top clamping inclined surfaces adapted to the abutting inclined surfaces. When the arc-shaped push-block plate and the arc-shaped top clamping plate cooperate to form a completed round tube support surface inside the mounting hole of the workpiece, part of the force on the arc-shaped push-block plate can be evenly and obliquely transferred to the arc-shaped top clamping plate, thereby improving the force dispersion effect during the spinning process and improving the structural stability between the arc-shaped push-block plate and the arc-shaped top clamping plate during the force process.

[0019] 3) Since the push-block shaft needs to be provided with inverted T-shaped grooves with different inclination angles to drive the slide bar installed on the arc-shaped push-block plate and the arc-shaped top tightening plate, the connecting rod and the slide bar cannot be provided at the bottom of the arc-shaped push-block plate and the arc-shaped top tightening plate due to the travel limit between the components, resulting in the lack of necessary support at the bottom of the circular tube support surface formed by the arc-shaped push-block plate and the arc-shaped top tightening plate. To this end, the present invention further provides a plurality of fixed blocks located on the inner side of the arc-shaped top tightening plate at intervals on the rotating base, and corresponding swing rods are swingably installed on the fixed blocks. When the lifting seat descends to the position to fix and clamp the workpiece between the lifting seat and the rotating base, the bottom end of the fixed cylinder forms a downward pressure on the inner end of the swing rod, so that the outer end of the swing rod is fixed and tightened to the bottom side of the inner wall of the arc-shaped top tightening plate, thereby effectively forming a reinforced support for the bottom side of each arc-shaped top tightening plate; in addition, part of the force on the arc-shaped push-block plate can be evenly and dispersedly transferred to the arc-shaped top tightening plate in an oblique direction. Thereby, it can be effectively ensured that a more stable support is formed on the bottom of the circular tube supporting surface formed by the arc-shaped push plate and the arc-shaped top tightening plate.

[0020] 4) The top ends of the arc-shaped push plate and the arc-shaped top clamping plate of the present invention are respectively in an inverted L-shape and fixedly connected outwardly with corresponding buffer pressure plates, and the middle part of the lifting seat is integrally formed with a mounting truncated table downwardly provided for connecting to the fixed cylinder, and the outer edge of the mounting truncated table is located on the outer side of the fixed cylinder. When the lifting seat is pressed against the upper side of the buffer pressure plate when it moves downward, the outer edge of the mounting truncated table forms a travel limit for the inner side of the buffer pressure plate after the compression deformation, so as to ensure that the buffer pressure plate can be fixed between the lifting seat and the top end of the workpiece in a more stably extruded state, so as to help improve the clamping effect of the workpiece.

[0021] 5) The coolant container of the coolant atomization mechanism of the present invention is fixedly installed on the top of the connecting piece, and by adding a duct and a fan, the atomized coolant is synchronously blown into the mounting groove on the inner side of the partition during the rotation of the spinning wheel; and then by adding a plurality of arc-shaped blade plates, the atomized coolant is continuously pushed out of the guide hole of the partition during the rotation of the spinning wheel, so that it is directly and evenly attached to the spinning wheel during the rotation, thereby achieving uniform cooling of the spinning wheel, so as to achieve uniform cooling and temperature reduction treatment of the spinning wheel at a low cost, thereby effectively maintaining the spinning processing accuracy of the spinning wheel on the workpiece.

[0022] 6) The several arc-shaped blade plates of the present invention are respectively fixed to the corresponding rotating wheels at equal intervals, and the rotating wheels are rotatably installed on the connecting parts through the corresponding fixed shafts; the driving shaft of the fan is connected to the fixed shaft through a belt drive, and the fixed shaft is connected to the connecting shaft through a belt drive. The driving power source of the several arc-shaped blade plates and the fan directly adopts 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 is synchronously output to cool the spinning wheel. It can reduce the consumption of coolant and the energy consumption required for driving the arc-shaped blade plates and the fan; and it can prevent the coolant from being continuously output to the spinning wheel that is not rotating, so as to prevent the spinning wheel from being deformed due to uneven temperature as a whole, thereby ensuring the practical effect of the present invention.

[0023] 7) A group of sealing plates are fixedly connected to the inner side of the partition of the present invention according to the height, and corresponding magnets are fixedly connected to the two sides of the sealing plates respectively. The rotating wheel is rotatably installed on the fixed shaft through the corresponding one-way bearings. Along the rotatable direction of the one-way bearings, magnetic metal parts corresponding to the magnets are fixedly connected to the front side surfaces of the outer ends of the arc-shaped blade plates respectively, and the distance between the ends of two or more adjacent arc-shaped blade plates is equal to the distance between the two magnets. When the spinning wheel stops rotating, under the action of the magnetic attraction of 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 closure on the guide holes on the partition. This is 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.

The outer sides of the connecting pieces 3022 are respectively provided with corresponding mounting grooves inclined downwardly. The spinning wheels 3021 are rotatably mounted to the outer sides of the mounting grooves through corresponding connecting shafts 3023. The atomizing cooling mechanism 303 is used to generate atomizing cooling liquid and transport the atomizing cooling liquid to the surface of the spinning wheel 3021 during the rotating process.

[0035] The present invention is additionally provided with a covering inner hole limit assembly 202, which can simultaneously form an outward push drive for the arc-shaped push plate 2022 and the arc-shaped top clamping plate 2023 under the drive of the inverted T-shaped groove 2033 of the push shaft 2031 of the limit drive mechanism 203, and the moving speed of the arc-shaped top clamping plate 2023 is greater than that of the arc-shaped push plate 2022, so that when the lifting seat 2012 moves down into position to clamp the workpiece 22 between the lifting seat 2012 and the rotating base 2011, the arc-shaped push plate 2022 and the arc-shaped top clamping plate 2023 are simultaneously pushed outward into position, so that the arc-shaped push plate 2022 and the arc-shaped top clamping plate 2023 form a complete circular tube support surface at the mounting hole of the workpiece 22. It can not only fix the upper and lower ends of the workpiece 22, but also form a complete round tube support surface at the mounting hole of the workpiece 22, thereby effectively ensuring the overall clamping effect of the workpiece 22 and reducing the deformation of the mounting hole of the workpiece 22 caused by the spinning process.

[0036] The atomizing cooling mechanism 303 comprises a cooling liquid container 3031, the cooling liquid container 3031 is fixedly mounted on the top of the connecting piece 3022, an ultrasonic atomizing sheet 3032 for processing the cooling liquid into atomized liquid is fixedly mounted on the inner bottom side of the cooling liquid container 3031, a corresponding partition 4 is fixedly connected to the mounting groove on the inner side of the spinning wheel 3021, a corresponding guide hole 401 is arranged in the middle of the partition 4, and corresponding closing plates 402 are fixedly connected to the two sides of the mounting groove on the inner side of the partition 4; a corresponding guide hole 401 is installed through the top of the connecting piece 3022 Tube 5, the bottom of the conduit 5 is connected to the mounting groove on the inner side of the partition 4, the top of the conduit 5 extends to the upper side of the coolant container 3031, a corresponding fan 6 is fixedly installed on the upper part of the coolant container 3031, and the driving shaft 601 of the fan 6 is transmission-connected to the connecting shaft 3023; a plurality of arc-shaped blade plates 7 are rotatably arranged in the mounting groove on the inner side of the partition 4; when the spinning wheel 3021 rotates, a plurality of the arc-shaped blade plates 7 rotate to push out the cooling atomized liquid in the mounting groove to cool the spinning wheel 3021 during the rotation process.

[0037] The coolant container 3031 of the coolant atomization mechanism 303 of the present invention is fixedly installed on the top of the connecting piece 3022. By adding a duct 5 and a fan 6, the atomized coolant is synchronously blown into the mounting groove on the inner side of the partition 4 during the rotation of the spinning wheel 3021. Then, by adding a plurality of arc-shaped blade plates 7, the atomized coolant is continuously pushed out of the guide hole 401 of the partition 4 during the rotation of the spinning wheel 3021, so that it is directly and evenly attached to the spinning wheel 3021 during the rotation, thereby achieving uniform cooling of the spinning wheel 3021, so as to achieve uniform cooling and temperature reduction treatment of the spinning wheel 3021 at a low cost, thereby effectively maintaining the spinning processing accuracy of the spinning wheel 3021 on the workpiece 22.

The fixed blocks 20 are respectively swingably mounted with corresponding swing rods 21. When the lifting seat 2012 moves down into position to fix and clamp the workpiece 22 between the lifting seat 2012 and the rotating base 2011, the bottom end of the fixed cylinder 2021 presses down on the inner end of the swing rod 21, so that the outer end of the swing rod 21 is fixedly clamped to the bottom side of the inner side wall of the arc-shaped clamping plate 2023, and the outer ends of the swing rods 21 are respectively fixedly connected to arc-shaped rod members 23 abutting against the lower side of the arc-shaped clamping plate 2023.

[0045] Since an inverted T-shaped groove 2033 with different inclination angles needs to be set on the push and stop shaft 2031 to drive the sliding rod 2025 installed on the arc-shaped push and stop plate 2022 and the arc-shaped top clamping plate 2023, due to the travel limitation between the components, the connecting rod 2024 and the sliding rod 2025 cannot be set at the bottom of the arc-shaped push and stop plate 2022 and the arc-shaped top clamping plate 2023, resulting in a lack of necessary support at the bottom of the circular tube support surface formed by the arc-shaped push and stop plate 2022 and the arc-shaped top clamping plate 2023. To this end, the present invention further provides a plurality of fixed blocks 20 located inside the arc-shaped top plate 2023 at intervals on the rotating base 2011, and corresponding swing rods 21 are swingably mounted on the fixed blocks 20. When the lifting base 2012 moves down to the position to fix and clamp the workpiece 22 between the lifting base 2012 and the rotating base 2011, the bottom end of the fixed cylinder 2021 presses down on the inner end of the swing rod 21, so that the outer end of the swing rod 21 is fixedly pressed against the bottom side of the inner wall of the arc-shaped top plate 2023, thereby effectively forming a reinforced support for the bottom side of each arc-shaped top plate 2023; in addition, part of the force of the arc-shaped push plate 2022 can be evenly and dispersedly transferred to the arc-shaped top plate 2023. Thus, it can be effectively ensured that a more stable support is formed on the bottom of the circular tube support surface formed by the arc-shaped push plate 2022 and the arc-shaped top plate 2023.

[0046] The top ends of the arc-shaped push-block plate 2022 and the arc-shaped top plate 2023 are respectively in an inverted L shape and fixedly connected to the corresponding buffer pressing plate 24, which is made of rubber material; the middle part of the lifting seat 2012 is integrally formed with a mounting truncated platform 25 for connecting the fixed cylinder 2021 downwardly, and the outer edge of the mounting truncated platform 25 is located on the outer side of the fixed cylinder 2021, and the lifting seat 2012 is pressed downward on the upper side of the buffer pressing plate 24, so that the buffer pressing plate 24 is fixed between the lifting seat 2012 and the top end of the workpiece 22 in an extruded state, and the outer edge of the mounting truncated platform 25 forms a travel limit on the inner side of the buffer pressing plate 24 after extrusion deformation. This ensures that the buffer pressing plate can be fixed between the lifting seat 2012 and the top end of the workpiece 22 in an extruded state more stably, so as to assist in improving the clamping effect of the workpiece 22.

[0047] A circle of corresponding guide protrusions 26 are arranged inwardly on the bottom side of the fixed cylinder 2021, and the push-blocking shaft 2031 can be movably inserted in the guide protrusion 26, and the upper side of the push-blocking shaft 2031 is arranged at a distance from the fixed cylinder 2021; the middle part of the rotating base 2011 is integrally formed with a push-blocking circular table 27 for blocking the push-blocking shaft 2031, and the fixed blocks 20 are respectively arranged on the rotating base 2011 outside the push-blocking circular table 27.

[0048] A pressure sensor is installed in the hydraulic system of the clamping cylinder 2013 in this embodiment, which can directly measure the pressure change inside the clamping cylinder 2013, so that the pushing thrust of the clamping cylinder 2013 can be controlled within a set range value, and then the tightening effect of the arc-shaped push plate 2022 and the arc-shaped tightening plate 2023 can be controlled. Slight assembly errors between components can be accommodated by the deformation of the buffer pressure plate 24.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
