Description

Technical Field

[0001] The present invention relates to the technical field of gear processing, and in particular to a gear hobbing processing system. Background Art

[0002] Gear hobbing belongs to the generating method. With the vertical feed of the hob, the required involute tooth profile can be hobbed on the workpiece.

[0003] For a workpiece with a center hole, when performing gear hobbing, one end of the workpiece is first placed on the main shaft, and then the other end of the workpiece is tightened using another rotating shaft. At this time, the main shaft can drive the workpiece and the rotating shaft to rotate simultaneously, and then the hob processes the workpiece. The above clamping method requires the workpiece to be installed manually or by an industrial robot arm. During manual installation, the workpiece position needs to be aligned and adjusted, which is time-consuming and affects processing efficiency. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a gear hobbing processing system, which can realize automatic loading and unloading of workpieces through a pushing mechanism and a lifting mechanism, thereby saving labor costs and improving processing efficiency.

[0005] The technical solutions adopted in the present invention are as follows:

[0006] A gear hobbing system includes a conveying mechanism, a lifting mechanism that rises and falls along the Z-axis, a pushing mechanism that moves along the X-axis, and a clamping mechanism that rotates around the X-axis.

[0007] A plurality of workpieces are placed on the conveying mechanism, and the lifting mechanism is arranged below the conveying mechanism. The lifting mechanism lifts the workpieces on the conveying mechanism to between the pushing mechanism and the clamping mechanism, or places the processed workpieces on the conveying mechanism;

[0008] The pushing mechanism can drive the workpiece on the lifting mechanism to enter or leave the clamping mechanism, and the clamping mechanism applies a radial clamping force to the workpiece;

[0009] A spindle is rotatably mounted on the movable end of the pushing mechanism, and the center line of the spindle is parallel to the X-axis direction. When the clamping mechanism clamps the workpiece, the spindle passes through the workpiece and presses the workpiece against the clamping mechanism.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The jacking mechanism lifts the workpiece on the conveying mechanism to between the pushing mechanism and the clamping mechanism, and then the pushing mechanism pushes the workpiece against the clamping mechanism for clamping. The pushing mechanism applies axial clamping force to the workpiece, and the clamping mechanism applies radial clamping force to the workpiece. During processing, the workpiece is less likely to slip and the processing accuracy is higher. After processing is completed, the pushing mechanism drives the workpiece out of the clamping mechanism and moves it to the jacking mechanism. The jacking mechanism places the processed workpiece on the conveying mechanism to realize automatic loading and unloading, save labor costs and improve processing efficiency.

[0012] As a preferred embodiment of the present invention, the movable end of the jacking mechanism is fixedly connected to an arc-shaped plate, the arc-shaped plate is used to support the workpiece, and both sides of the arc-shaped plate are fixedly connected to first limit plates, and the two first limit plates are used to prevent the workpiece from moving along the X-axis direction;

[0013] A tension sleeve and a pressure ring are fixedly connected to the outer periphery of the spindle. When the clamping mechanism clamps the workpiece, the tension sleeve is located on the inner wall of the workpiece, and the pressure ring presses the workpiece against the clamping mechanism.

[0014] Beneficial effect: by arranging the arc plate and the first limiting plate, the workpiece is limited when jacking or lowering the workpiece, so as to prevent the workpiece from detaching from the arc plate during the movement; when the workpiece is jacked between the pushing mechanism and the clamping mechanism, the pushing mechanism drives the mandrel to move, the mandrel passes through the workpiece, and the tensioning sleeve is squeezed into the inner wall of the workpiece. Due to the obstruction of the first limiting plate, the workpiece will not move during the squeezing process. When the clamping ring contacts one end of the workpiece, the tensioning sleeve is completely located in the workpiece, the arc plate descends, the workpiece detaches from the arc plate, and the pushing mechanism continues to drive the mandrel and the workpiece toward the clamping mechanism. The cam is moved in a reverse direction until the clamping ring presses the workpiece against the clamping mechanism, generating an axial clamping force on the workpiece. After the processing is completed, the pushing mechanism moves in the reverse direction, driving the spindle and the workpiece to separate from the clamping mechanism until the workpiece is above the arc plate. The lifting mechanism drives the arc plate to move upward until the arc plate contacts the side wall of the workpiece. At this time, the workpiece is blocked by the first limit plate, and the pushing mechanism continues to move in the reverse direction to pull the spindle out of the workpiece. By arranging a tensioning sleeve, the workpiece is not easily separated from the pushing assembly during movement, and the tensioning sleeve generates a radial clamping force on the workpiece from the inside to the outside, which has a better clamping effect on the workpiece.

[0015] As a preferred embodiment of the present invention, the clamping mechanism includes a rotating seat fixedly connected to the main shaft, an insertion hole is provided in the middle of the rotating seat along the X-axis direction, and a plurality of clamping members are provided around the insertion hole.

[0016] One end of the mandrel has the same radius as the insertion hole and extends out of the workpiece. After one end of the mandrel enters the insertion hole, the clamping member moves toward the workpiece until the workpiece is clamped.

[0017] Beneficial effects: The workpiece is clamped radially by multiple clamping parts arranged circumferentially, and the clamping effect is better. The insertion hole is provided to guide the spindle, making the operation of the pushing mechanism more stable and more precise.

[0018] As a preferred embodiment of the present invention, the rotating seat is provided with a plurality of vertical grooves and a plurality of transverse grooves circumferentially around the insertion hole, one end of each of the transverse grooves is communicated with the middle of the corresponding vertical groove, the other end of each of the transverse grooves is located on the contact surface between the rotating seat and the workpiece, and one end of each of the vertical grooves is communicated with the insertion hole;

[0019] Each of the clamping members includes a first oblique block, a vertical rod, a cross rod, a clamping block and a spring, the vertical rod being slidably installed in the vertical slot, one end of the vertical rod extending into the insertion hole and fixedly connected to the first oblique block, the other end of the vertical rod being fixedly connected to the spring, the spring being vertically arranged in the vertical slot, one end of the cross rod being fixedly connected to the vertical rod and vertically slidably installed in the cross slot, the other end of the cross rod extending out of the cross slot and fixedly connected to the clamping block;

[0020] One end of the spindle extending out of the workpiece is fixedly connected to a plurality of second inclined blocks. When the spindle enters the insertion hole, the inclined surface of the second inclined block presses against the inclined surface of the first inclined block, forcing the first inclined block, vertical rod, horizontal rod, and clamping block to move toward the workpiece until the clamping block clamps the workpiece.

[0021] Beneficial effect: By setting the second bevel block and the first bevel block, after the core shaft enters the insertion hole, the clamping block automatically clamps the workpiece to achieve automatic clamping. There is no need to set up an additional control system to control the clamping piece for clamping, which saves costs. Moreover, since the first bevel block is pressed against the second bevel block, the core shaft and the rotating seat are not easy to slip when they rotate coaxially.

[0022] As a preferred embodiment of the present invention, both sides of the first oblique block are fixedly connected with second limiting plates. When the second oblique block leans against the first oblique block, both sides of the second oblique block are in contact with the two second limiting plates respectively.

[0023] Beneficial effect: By setting the second limiting plate, the second inclined block and the corresponding first inclined block rotate synchronously, and during the rotation process, the clamping state of the clamping block is maintained.

[0024] As a preferred embodiment of the present invention, the conveying mechanism includes two obliquely parallel frames, the two ends of the workpiece roll downward along the two frames respectively, and the two frames are fixedly connected to third limit plates, and the two third limit plates are in contact with both sides of the workpiece;

[0025] The arc plate is located between the two frames, and a blocking plate is provided between the arc plate and the lifting mechanism. When the lifting mechanism drives the blocking plate and the arc plate to move upward, the arc plate pushes the workpiece away from the conveying frame, and the blocking plate blocks the workpiece above the conveying frame.

[0026] Beneficial effect: the workpiece is placed from the highest point of the frame and rolls downward along the frame until it is blocked by the workpiece below or the blocking plate. The lifting mechanism drives the arc plate, the blocking plate and the processed workpiece to move downward until the processed workpiece contacts the frame and loses the blocking of the arc plate. The processed workpiece rolls out downward along the frame, and the workpiece above rolls down following the processed workpiece. When it rolls to above the arc plate, the lifting mechanism drives the arc plate and the blocking plate to rise again, lifts the workpiece, and lifts it between the pushing mechanism and the clamping mechanism. At this time, the blocking plate blocks the remaining unprocessed workpieces again; through the above structure, automatic feeding is realized, and there is no need to set up an additional conveyor belt for transportation, which saves equipment costs. When the arc plate contacts the workpiece, when the workpiece is misaligned with the arc part, within a certain range, the workpiece will automatically roll to the center of the arc plate, realizing automatic calibration and high processing accuracy.

DETAILED DESCRIPTION

[0035] Typical embodiments that embody the features and advantages of the present invention are described in detail in the following description. It should be understood that the present invention is capable of various variations in different embodiments without departing from the scope of the present invention, and that the descriptions and illustrations are intended to be illustrative rather than limiting.

[0036] In the description of this application, the terms "first", "second", etc. are only used to facilitate the description of this application and simplify the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as a limitation on this application.

[0037] See also Figure 1 and Figure 2 As shown, this embodiment discloses a gear hobbing processing system, including a conveying mechanism 1, a lifting mechanism 2 that rises and falls along the Z-axis direction, a pushing mechanism 3 that moves along the X-axis direction, and a clamping mechanism 4 that rotates around the X-axis direction; a plurality of workpieces 5 are placed on the conveying mechanism 1, and the lifting mechanism 2 is arranged below the conveying mechanism 1. The lifting mechanism 2 lifts the workpiece 5 on the conveying mechanism 1 between the pushing mechanism 3 and the clamping mechanism 4, or places the processed workpiece 5 on the conveying mechanism 1; the pushing mechanism 3 can drive the workpiece 5 on the lifting mechanism 2 to enter or exit the clamping mechanism 4, and the clamping mechanism 4 applies a radial clamping force to the workpiece 5.

[0038] In this embodiment, the X-axis direction is the centerline direction of the workpiece 5 during machining, and the Z-axis direction is located on a vertical plane and is perpendicular to the X-axis direction.

[0039] Among them, see Figure 2The conveying mechanism 1 includes two obliquely parallel frames 11, and the two ends of the workpiece 5 roll downward along the two frames 11 respectively. The two frames 11 are fixedly connected with a third limit plate 12, and the two third limit plates 12 are in contact with both sides of the workpiece 5; the jacking mechanism 2 adopts a hydraulic cylinder, and the piston rod of the jacking mechanism 2 is fixedly connected with a blocking plate 21, and the upper end of the blocking plate 21 is fixedly connected with an arc plate 22, and the arc plate 22 is used to support the workpiece 5 and is located between the two frames 11. Both sides of the arc plate 22 are fixedly connected with a first limit plate 23, and the two first limit plates 23 are used to prevent the workpiece 5 from moving along the X-axis direction.

[0040] In this embodiment, the workpiece 5 is placed from the highest point of the frame 11 and rolls downward along the frame 11 until it is blocked by the workpiece 5 below or the blocking plate 21. The lifting mechanism 2 drives the arc plate 22, the blocking plate 21 and the processed workpiece 5 to move downward until the processed workpiece 5 contacts the frame 11 and loses the obstruction of the arc plate 22. The processed workpiece 5 rolls downward along the frame 11, and the upper workpiece 5 follows the processed workpiece 5 and rolls downward. When it rolls to above the arc plate 22, the lifting mechanism 2 drives the arc plate 22 and the blocking plate 21 to rise again, lift the workpiece 5, and lift it between the pushing mechanism 3 and the clamping mechanism 4. The blocking plate 21 again blocks the remaining unprocessed workpieces 5 to realize automatic loading and unloading.

[0041] In other embodiments, the conveying mechanism 1 may adopt two parallel conveyor belts, and the lifting mechanism 2 may adopt a pneumatic cylinder or an electric cylinder.

[0042] Among them, see Figure 3 、 Figure 4 and Figure 5 The pushing mechanism 3 adopts a hydraulic cylinder, and the piston rod of the pushing mechanism 3 is rotatably installed with a spindle 31. The center line of the spindle 31 is parallel to the X-axis direction. When the clamping mechanism 4 clamps the workpiece 5, the spindle 31 passes through the workpiece 5 and presses the workpiece 5 against the clamping mechanism 4; the outer periphery of the spindle 31 is fixedly connected with a tightening sleeve 32 and a clamping ring 33. The tightening sleeve 32 adopts an elastic sleeve, and the outer diameter of the tightening sleeve 32 is larger than the inner diameter of the workpiece 5. When the clamping mechanism 4 clamps the workpiece 5, the tightening sleeve 32 is located on the inner wall of the workpiece 5, and the clamping ring 33 presses the workpiece 5 against the clamping mechanism 4.

[0043] In this embodiment, when the workpiece 5 is lifted between the pushing mechanism 3 and the clamping mechanism 4, the pushing mechanism 3 drives the spindle 31 to move, the spindle 31 passes through the workpiece 5, and the tensioning sleeve 32 is squeezed into the inner wall of the workpiece 5. Due to the obstruction of the first limit plate 23, the workpiece 5 does not move during the squeezing process. When the clamping ring 33 contacts one end of the workpiece 5, the tensioning sleeve 32 is completely located in the workpiece 5, the arc plate 22 descends, and the workpiece 5 is separated from the arc plate 22. The pushing mechanism 3 continues to drive the spindle 31 and the workpiece 5 toward the clamping mechanism 4 until the clamping ring 33 presses the workpiece 5 against the clamping mechanism 4. The workpiece 5 generates an axial clamping force; after the processing is completed, the pushing mechanism 3 moves in the reverse direction, driving the spindle 31 and the workpiece 5 to separate from the clamping mechanism 4 until the workpiece 5 is located above the arc plate 22, and the lifting mechanism 2 drives the arc plate 22 to move upward until the arc plate 22 contacts the side wall of the workpiece 5. At this time, the workpiece 5 is blocked by the first limit plate 23, and the pushing mechanism 3 continues to move in the reverse direction to pull the spindle 31 out of the workpiece 5; by providing a tensioning sleeve 32, the workpiece 5 is not easy to separate from the pushing component during the movement, and the tensioning sleeve 32 generates a radial clamping force on the workpiece 5 from the inside to the outside, which has a better clamping effect on the workpiece 5.

[0044] In other embodiments, the pushing mechanism 3 may be a pneumatic cylinder or an electric cylinder.

[0045] Among them, see Figure 3 and Figure 7 The clamping mechanism 4 includes a rotating seat 41 fixedly connected to the main shaft, an insertion hole 411 is provided in the middle of the rotating seat 41 along the X-axis direction, and a plurality of clamping members are arranged around the insertion hole 411 on the rotating seat 41; a plurality of vertical grooves 412 and a plurality of transverse grooves 413 are opened around the insertion hole 411 on the rotating seat 41, one end of each of the transverse grooves 413 is respectively communicated with the middle of the corresponding vertical groove 412, and the other end of each of the transverse grooves 413 is located on the contact surface between the rotating seat 41 and the workpiece 5, and one end of each of the vertical grooves 412 is communicated with the insertion hole 411;

[0046] See Figure 6 , each of the clamping members includes a first oblique block 42, a vertical rod 43, a cross rod 44, a clamping block 45 and a spring 46, the vertical rod 43 is slidably installed in the vertical slot 412, one end of the vertical rod 43 extends into the insertion hole 411 and is fixedly connected to the first oblique block 42, the other end of the vertical rod 43 is fixedly connected to the spring 46, the spring 46 is vertically arranged in the vertical slot 412, one end of the cross rod 44 is fixedly connected to the vertical rod 43, and is vertically slidably installed in the cross slot 413, the other end of the cross rod 44 extends out of the cross slot 413 and is fixedly connected to the clamping block 45;

[0047] See Figure 4 and Figure 5The end of the spindle 31 extending out of the workpiece 5 is fixedly connected to a plurality of second inclined blocks 34. In the initial state, the upper end surface of the cross bar 44 contacts the top surface of the cross groove 413. When the spindle 31 enters the insertion hole 411, the inclined surface of the second inclined block 34 rests on the inclined surface of the first inclined block 42, forcing the first inclined block 42, the vertical rod 43, the cross bar 44, and the clamping block 45 to move toward the workpiece 5. The lower end surface of the cross bar 44 contacts the bottom surface of the cross groove 413. At this time, the clamping block 45 clamps the workpiece 5, realizing automatic clamping.

[0048] Among them, the two sides of the first inclined block 42 are fixedly connected with the second limit plates 47. When the second inclined block 34 is pressed against the first inclined block 42, the two sides of the second inclined block 34 are respectively in contact with the two second limit plates 47, so that the second inclined block 34 rotates synchronously with the corresponding first inclined block 42, and during the rotation process, the clamping state of the clamping block 45 is maintained.

[0049] The usage and principle of this embodiment are as follows:

[0050] The workpiece 5 is placed from the highest point of the frame 11, and the workpiece 5 rolls downward along the frame 11 until it is blocked by the workpiece 5 below or the blocking plate 21. The lifting mechanism 2 drives the curved plate 22 and the blocking plate 21 to move downward until the workpiece 5 is no longer blocked. When it rolls above the curved plate 22, the lifting mechanism 2 drives the curved plate 22 and the blocking plate 21 to rise again. The two first limiting plates 23 limit the two sides of the workpiece 5, lift the workpiece 5, and lift it between the pushing mechanism 3 and the clamping mechanism 4.

[0051] The pushing mechanism 3 drives the mandrel 31 to move, and the tensioning sleeve 32 is squeezed into the inner wall of the workpiece 5. Due to the obstruction of the first limit plate 23, the workpiece 5 does not move during the squeezing process. When the clamping ring 33 contacts one end of the workpiece 5, the tensioning sleeve 32 is completely located in the workpiece 5, and the lifting mechanism 2 drives the curved plate 22 to descend, and the workpiece 5 is separated from the curved plate 22.

[0052] The pushing mechanism 3 continues to drive the spindle 31 and the workpiece 5 toward the clamping mechanism 4. When the spindle 31 enters the insertion hole 411, the inclined surface of the second inclined block 34 presses against the inclined surface of the first inclined block 42. The second inclined block 34 contacts the second limiting plate 47, forcing the first inclined block 42, the vertical rod 43, the horizontal rod 44, and the clamping block 45 to move toward the center of the workpiece 5. The spring 46 is stretched until the clamping block 45 clamps the workpiece 5.

[0053] The clamping mechanism 4 has a good clamping effect on the workpiece 5 by utilizing the axial clamping force applied by the clamping ring 33 to the workpiece 5, the radial pressing force from the inside to the outside of the workpiece 5 by the expansion sleeve 32, and the radial pressing force from the outside to the inside of the workpiece 5 by the clamping block. By providing the second limit plate 47, the second inclined block 34 and the corresponding first inclined block 42 rotate synchronously. During the rotation process, the clamping state of the clamping block 45 is maintained, thereby ensuring the processing accuracy.

[0054] The main shaft drives the rotating shaft, the spindle 31 and the workpiece 5 to rotate coaxially to perform gear hobbing;

[0055] After the processing is completed, the pushing mechanism 3 drives the spindle 31 and the processed workpiece 5 to move in the opposite direction. The spring 46 causes the clamping block 45 to separate from the processed workpiece 5 due to its elasticity. When the processed workpiece 5 is above the curved plate 22, the lifting mechanism 2 drives the curved plate 22 to move upward until the curved plate 22 contacts the side wall of the processed workpiece 5. At this time, the processed workpiece 5 is blocked by the first limit plate 23, and the pushing mechanism 3 continues to move in the opposite direction to pull the spindle 31 out of the processed workpiece 5.

[0056] The lifting mechanism 2 drives the arc plate 22, the blocking plate 21 and the processed workpiece 5 to move downward until the processed workpiece 5 contacts the frame 11 and loses the obstruction of the arc plate 22. The processed workpiece 5 rolls down along the frame 11, and the workpiece 5 above follows the processed workpiece 5 and rolls down. When it rolls above the arc plate 22, the lifting mechanism 2 drives the arc plate 22 and the blocking plate 21 to rise again, lift the workpiece 5, and lift it between the pushing mechanism 3 and the clamping mechanism 4. At this time, the blocking plate 21 again blocks the remaining unprocessed workpieces 5.

[0057] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
