Description

TECHNICAL FIELD

[0001] The present application relates to the field of surface processing equipment, in particular to a large-diameter cylindrical workpiece split clamping driving device, and further relates to a large-diameter cylindrical workpiece spraying equipment. BACKGROUND

[0002] Workpiece surface processing generally refers to mechanical processing such as turning, grinding or polishing on the outer surface of the workpiece, or surface treatment processing such as painting, oxidation or heat treatment on the outer surface of the workpiece. When processing the surface of the workpiece, the workpiece is usually clamped on the processing equipment, the processing surface of the workpiece is exposed, and the workpiece is driven to rotate so as to process different parts of the outer surface of the workpiece.

[0003] Workpiece surface processing is usually performed in a specific area, especially when the workpiece is surface treated. For example, when the workpiece is painted, it needs to be done in a paint room. At this time, the workpiece needs to be transported to the paint room first, and then clamped on the rotating spindle, and the workpiece is driven to rotate, and the paint spraying head moves to different positions on the workpiece surface to perform the painting operation. For workpieces with small mass, a conveying mechanism such as a conveyor belt can be used to convey the workpiece. When the workpiece is conveyed to the painting station, the workpiece is lifted to a position opposite the rotating spindle, and the workpiece is clamped on the rotating spindle. For workpieces with large mass, it is not possible to convey and automatically clamp them by using a conveying mechanism.

[0004] Currently, when processing the surface of a large-diameter cylindrical workpiece, a forklift, a crane or other transfer equipment is usually used to transfer the workpiece to the processing station, and then the large-diameter cylindrical workpiece is lifted to a position corresponding to the rotating spindle, and the large-diameter cylindrical workpiece is manually clamped. The clamping time is long, and the clamping work is performed at the processing station. When the processing station has a small environment space, lacks large transfer equipment or it is difficult for large transfer equipment to enter, it is difficult to clamp the workpiece. Long-time workpiece clamping operation in a harsh environment such as a paint room can also adversely affect the health of the operator. SUMMARY

[0042] In the present specification, the terms "first", "second" are only used for the purpose of description and can not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated, therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features.

[0043] One embodiment of the large-diameter cylindrical workpiece split clamping driving device of the present application, as shown in Figure 1 The clamping transfer trolley 1 and the rotary driving table 2 are independent of each other.

[0044] The clamping transfer trolley 1 includes a transfer trolley body 11, a first inner support seat 12 and a second inner support seat 13. The transfer trolley body 11 is provided in a long strip shape as a whole, and the length and width of the transfer trolley body 11 are determined according to the length and diameter of the cylindrical workpiece to be transferred, usually according to the maximum length and maximum diameter of the cylindrical workpiece to be transferred. Walking wheels are provided below the transfer trolley body 11, so that the transfer trolley body 11 can be conveniently moved on the ground, facilitating the transfer of the large-diameter cylindrical workpiece by the transfer trolley body 11.

[0045] The first inner support seat 12 and the second inner support seat 13 are both provided on the transfer trolley body 11 and are oppositely arranged on the transfer trolley body 11. The first inner support seat 12 and the second inner support seat 13 can be respectively supported in the inner holes at the two ends of the large-diameter cylindrical workpiece, clamping the large-diameter cylindrical workpiece between the first inner support seat 12 and the second inner support seat 13, so that the outer side surface of the large-diameter cylindrical workpiece is completely exposed, and at the same time the large-diameter cylindrical workpiece can rotate on the first inner support seat 12 and the second inner support seat 13, so that the entire outer side surface of the large-diameter cylindrical workpiece can be processed without obstruction, such as painting.

[0046] The clamping of the large-diameter cylindrical workpiece can be carried out at a position away from the machining station, so that the clamping process is away from the harmful working environment of the machining station, reducing the residence time of the operator in the harmful environment. In addition, the clamping operation can be carried out in a place with better lifting equipment, facilitating the lifting and clamping of large-diameter cylindrical workpieces with large quality.

[0047] A rotary driving member 121 is provided on the first inner support seat 12, which is coaxially arranged with the large-diameter cylindrical workpiece, and the large-diameter cylindrical workpiece can be driven to rotate on the first inner support seat 12 and the second inner support seat 13 by the rotary driving member 121.

[0048] The rotating driving table 2 is fixedly arranged on the bottom surface, and is usually fixedly arranged at a machining station, such as inside a paint room. The rotating driving table 2 is provided with a rotating driving mechanism 21 and a separable driving head 22, wherein the separable driving head 22 is in transmission connection with the rotating driving mechanism 21, such as being connected through a transmission belt, and when the rotating driving mechanism 21 works, the separable driving head 22 can be driven to rotate.

[0049] By moving the clamping transfer trolley 1 to the direction close to the rotating driving table 2, the rotating driving part 121 on the first inner support seat 12 can be close to the separable driving head 22 on the rotating driving table 2. When the clamping transfer trolley 1 moves to the set position on one side of the rotating driving table 2, the driving connection is formed between the separable driving head 22 and the rotating driving part 121. At this time, the rotating driving part 121 can be driven to rotate by the rotation of the separable driving head 22, and the large-diameter cylindrical workpiece clamped on the clamping transfer trolley 1 is driven to rotate. At the same time, the machining head on the machining station moves to machine the outer peripheral surface of the large-diameter cylindrical workpiece. For example, the paint spraying head approaches the outer surface of the cylindrical workpiece and slowly moves along the axial direction of the cylindrical workpiece to perform the paint spraying operation on the outer peripheral surface of the cylindrical workpiece.

[0050] After the machining is completed, the separable driving head 22 stops rotating and separates from the rotating driving part 121. At this time, the clamping transfer trolley 1 moves to transfer the large-diameter cylindrical workpiece to the next process, and after the large-diameter cylindrical workpiece is removed from the clamping transfer trolley 1, the machining in the subsequent process is performed.

[0051] In some embodiments of the large-diameter cylindrical workpiece separable clamping and driving device, as shown in Figures 1 to 3 One end of the rotating driving part 121 is provided with a cylindrical matching hole, and the separable driving head 22 includes a driving plate 221, a sliding support block 222 and a support block driving structure. The driving plate 221 is a circular plate, and the driving plate 221 is in driving connection with the rotating driving mechanism 21, and when the rotating driving mechanism 21 works, the driving plate 221 can be driven to rotate.

[0052] The sliding support block 222 is provided in plurality, and is usually provided in three. The periphery of the driving plate 221 is uniformly provided with the same number of radial sliding grooves, and the sliding support block 222 is installed on the driving plate 221 through the radial sliding grooves and can slide along the radial sliding grooves on the driving plate 221. The diameter of the driving plate 221 is smaller than the diameter of the cylindrical matching hole, and when the sliding support block 222 slides to the outer periphery of the driving plate 221, the outer side edges of the sliding support block 222 protrude from the circumferential surface of the driving plate 221, so that the diameter of the circumscribed circle formed by the outer side surfaces of the plurality of sliding support blocks 222 is greater than the diameter of the cylindrical matching hole.

[0053] The support block driving structure can use various structures capable of pushing the plurality of sliding support blocks 222 to slide synchronously on the driving plate 221. When the clamping transfer trolley 1 moves to the side of the rotary driving table 2, the detachable driving head 22 is inserted into the cylindrical matching hole on the rotary driving member 121, the support block driving structure drives the plurality of sliding support blocks 222 to slide to the radial outside of the driving plate 221, so that the outer side surface of the plurality of sliding support blocks 222 abuts against the inner wall of the cylindrical matching hole, and the two are connected through static friction to form a driving connection, so that the rotary driving member 121 rotates synchronously with the detachable driving head 22. The control support block driving structure drives the plurality of sliding support blocks 222 to slide to the center of the driving plate 221, and the sliding support blocks 222 are separated from the inner wall of the cylindrical matching hole, so that pushing the clamping transfer trolley 1 moves can make the clamping transfer trolley 1 leave the rotary driving table 2, and transfer the large-diameter cylindrical workpiece away from the machining station.

[0054] In a preferred embodiment of the large-diameter cylindrical workpiece detachable clamping driving device of the present application, as shown in Figures 2 to 4 The rotary driving table 2 further comprises a rotary support frame 23, and is fixed to the ground through the rotary support frame 23. The center of the driving plate 221 is provided with a driving plate rotating shaft 223 perpendicular to the driving plate 221, the driving plate rotating shaft 223 is installed on the top of the rotary support frame 23 through a bearing, and a driving plate pulley is fixedly arranged at the other end of the driving plate rotating shaft 223. The rotary driving mechanism 21 uses a motor, the rotary driving mechanism 21 is fixed on the rotary support frame 23, a motor pulley is fixedly arranged on the output shaft of the rotary driving mechanism 21, and the motor pulley and the driving plate pulley are connected through a transmission belt. When the rotary driving mechanism 21 works, the driving plate 221 can be driven to rotate through the transmission belt.

[0055] The support block driving structure comprises a support block driver 224, a support block shift fork 225, a moving sliding ring 226 and a sliding support rod 227. The support block driver 224 can use various driving devices capable of generating linear pushing action, such as electric push rod, air cylinder, hydraulic cylinder, etc., and an air cylinder is used in the embodiment.

[0056] The support block driver 224 is fixed on the rotating support frame 23, the moving sliding ring 226 is sleeved on the driving plate rotating shaft 223 adjacent to the driving plate 221, and a fork sliding groove is arranged on the outer circumferential surface of the moving sliding ring 226. The middle part of the fork handle of the support block fork 225 is hinged on the rotating support frame 23, and the fork head of the support block fork 225 is clamped in the fork sliding groove. Specifically, the fork head of the support block fork 225 can be directly clamped in the fork sliding groove, or a clamping sliding block can be arranged on the inner side of the fork head of the support block fork 225, and the clamping sliding block is clamped in the fork sliding groove. The end of the fork handle of the support block fork 225 is hinged with the output shaft of the support block driver 224, the end of the fork handle of the support block fork 225 is pushed by the output shaft of the support block driver 224, and the moving sliding ring 226 is pushed to move axially on the driving plate rotating shaft 223 by the lever action of the support block fork 225.

[0057] The hinged protrusion is arranged on one end of the moving sliding ring 226 adjacent to the driving plate 221 and opposite to the radial sliding groove on the driving plate 221, and the hinged groove is arranged on the inner side of the sliding support block 222. One end of the sliding support rod 227 is hinged with the hinged protrusion on the moving sliding ring 226, and the other end is hinged in the hinged groove on the sliding support block 222. When the moving sliding ring 226 moves towards the driving plate 221, the sliding support blocks 222 connected by the plurality of sliding support rods 227 are simultaneously moved in the circumferential direction of the driving plate 221 by the plurality of sliding support rods 227; and when the moving sliding ring 226 moves away from the driving plate 221, the sliding support blocks 222 connected by the plurality of sliding support rods 227 are simultaneously moved in the direction of the center of the driving plate 221 by the plurality of sliding support rods 227.

[0058] In some embodiments of the large-diameter cylindrical workpiece split clamping driving device of the present application, as shown in Figure 2 and Figure 3 The rotating mounting seat 24 is further arranged at the bottom of the rotating driving table 2, and the rotating mounting seat 24 comprises a mounting seat bottom plate 241, a moving mounting plate 242 and a mounting plate moving cylinder 243.

[0059] The mounting seat bottom plate 241 is fixedly installed on the ground, and the moving sliding rail parallel to the driving plate rotating shaft 223 is arranged on the mounting seat bottom plate 241. The moving mounting plate 242 is installed on the moving sliding rail through a sliding block and can slide on the mounting seat bottom plate 241 in a direction parallel to the driving plate rotating shaft 223. The cylinder body of the mounting plate moving cylinder 243 is hinged with the mounting seat bottom plate 241, the piston rod is hinged with the moving mounting plate 242, and the hinge shafts at both ends of the mounting plate moving cylinder 243 are perpendicular to each other.

[0060] Both the rotary drive mechanism 21 and the separable drive head 22 are mounted on the movable mounting plate 242, typically via a rotary support frame 23. When the mounting plate moving cylinder 243 is activated, it can push the rotary support frame 23 and the separable drive head 22 mounted on the rotary support frame 23 to move axially, causing the separable drive head 22 to insert into or disengage from the cylindrical mating hole on the rotary drive component 121.

[0061] In a preferred embodiment of the large-diameter cylindrical workpiece separable clamping drive device of this application, such as Figure 2 and Figure 3 As shown, the rotating mounting base 24 is also provided with a height adjustment plate 244. The height adjustment plate 244 is installed on the movable mounting plate 242 by a height adjustment structure such as a height adjustment screw or a height adjustment cylinder, and the installation height of the height adjustment plate 244 on the movable mounting plate 242 can be adjusted by the height adjustment structure.

[0062] A waist-shaped mounting hole perpendicular to the drive plate shaft 223 is provided at the bottom of the rotating support frame 23. The rotating support frame 23 is fixed to the height adjustment plate 244 through the waist-shaped mounting hole, and the lateral position of the rotating support frame 23 on the height adjustment plate 244 can be adjusted. By adjusting the height of the height adjustment plate 244 and the lateral position of the rotating support frame 23, when the clamping and transfer carriage 1 moves to the set position, the axis of rotation of the separable drive head 22 coincides with the axis of rotation of the rotating drive component 121, ensuring that the separable drive head 22 and the rotating drive component 121 can be smoothly connected and rotate coaxially.

[0063] In some embodiments of the large-diameter cylindrical workpiece separable clamping drive device of this application, such as Figure 1 As shown, the first inner support base 12 includes a first mounting base 122 and an inner support clamp 14.

The end of the rotation shaft passes through the first mounting base 122 and is fixedly connected to the rotation drive member 121.

[0064] The second inner support 13 includes a second mounting base 131 and an inner support clamp 14. Mounting rails parallel to the rotation axis of the inner support clamp 14 are provided on both sides of the transfer vehicle body 11. The bottom of the second mounting base 131 is mounted on the mounting rails and can slide along the mounting rails on the transfer vehicle body 11. The height of the second mounting base 131 is the same as the height of the first mounting base 122. The rotation axis of the inner support clamp 14 is fixed to the top of the second mounting base 131 by bearings, and its rotation axis is coaxial with the rotation axis of the inner support clamp 14 on the first mounting base 122.

[0065] When the second mounting seat 131 moves on the transfer trolley body 11, the axial distance between the inner support clamp 14 on the second mounting seat 131 and the inner support clamp 14 on the first mounting seat 122 can be changed, facilitating the clamping and dismounting operation of the large-diameter cylindrical workpiece on the clamping transfer trolley 1, and enabling the clamping of large-diameter cylindrical workpieces of different lengths on the clamping transfer trolley 1, thereby improving the applicability of the large-diameter cylindrical workpiece split clamping driving device. A slide rail protective cover can also be arranged above the mounting seat slide rail to prevent machining chips or paint droplets generated during machining of the workpiece from adhering to the mounting seat slide rail, thereby affecting the smooth sliding of the second mounting seat 131.

[0066] In a preferred embodiment of the large-diameter cylindrical workpiece split clamping driving device, as shown in Figures 5 to 7 The inner support clamp 14 includes a clamp positioning plate 141, a clamp driving disc 142, radial slide bars 143, support blocks 144, and slide bar driving wheels 145. The clamp positioning plate 141 is installed on the top of the first mounting seat 122 or the second mounting seat 131 through a rotating shaft, so that the clamp positioning plate 141 can rotate on the first mounting seat 122 or the second mounting seat 131 to form a positioning reference surface for the end surface of the large-diameter cylindrical workpiece.

[0067] The clamp driving disc 142 is installed on the inner side of the clamp positioning plate 141, that is, the side close to the large-diameter cylindrical workpiece, and the diameter of the clamp driving disc 142 is smaller than that of the clamp positioning plate 141. The clamp driving disc 142 can rotate on the clamp positioning plate 141, and the rotating shaft is the same as that of the clamp positioning plate 141. A plurality of involute-shaped sliding grooves are arranged on the clamp driving disc 142, the distance between different parts of the involute-shaped sliding groove and the center of the clamp driving disc 142 gradually increases from one end to the other end, and the plurality of involute-shaped sliding grooves are symmetrically arranged with respect to the center of the clamp driving disc 142.

[0068] A plurality of radial slide bars 143 are arranged, and the number of radial slide bars 143 is the same as that of the involute-shaped sliding grooves. The plurality of radial slide bars 143 are uniformly installed on the clamp positioning plate 141 through sliding structures such as slide rails or sliding grooves, and can slide on the clamp positioning plate 141 along the rotating diameter direction of the clamp positioning plate 141. A connecting sliding block is fixedly arranged on one side of each radial slide bar 143 facing the clamp driving disc 142, and the connecting sliding block is slidingly installed in the involute-shaped sliding groove. When the clamp driving disc 142 rotates on the clamp positioning plate 141, the distance between the connecting sliding block and the center of the clamp positioning plate 141 changes with the sliding of the connecting sliding block in the involute-shaped sliding groove, thereby pushing the plurality of radial slide bars 143 to move radially on the clamp positioning plate 141 synchronously.

[0069] The support blocks 144 are provided in multiple numbers, and the multiple support blocks 144 are fixed on the multiple radial slides 143 in several groups respectively, one support block 144 in each group is fixed on each radial slide 143, and the support blocks 144 in each group are arranged in a circle with the center of the jig positioning plate 141 as the center on the multiple radial slides 143, and the support blocks 144 in multiple groups are arranged to form multiple concentric circles on the radial slides 143. A plurality of groups of support block mounting holes are provided on the radial slides 143, and each group of support block mounting holes forms a concentric circle. One group of support blocks 144 can be installed in different groups of support block mounting holes to form concentric circles of different radii. Different groups of support blocks 144 have different widths, and generally, the width of the support blocks 144 on the smaller diameter circle is smaller, and the width of the support blocks 144 on the larger diameter concentric circle is larger.

[0070] Generally, the distance difference between the two ends of the involute-shaped sliding groove and the center is small, such as 50 mm in a specific embodiment, and if only the rotation of the jig driving disc 142 is relied on to change the diameter of the cylindrical workpiece that can be clamped by the support blocks 144, only workpieces with a diameter difference of 100 mm can be clamped. By providing three groups of support blocks 144, eight groups of support block mounting holes are provided on each radial slide 143, and the distance between each group of support block mounting holes is 50 mm, so that the moving range of the support blocks 144 can be up to 400 mm, which is convenient for clamping large-diameter cylindrical workpieces with a hole diameter of 300-1000 mm.

[0071] The slide driving wheel 145 is provided on the outer side of the jig positioning plate 141, that is, the side away from the large-diameter cylindrical workpiece, and the rotating shaft of the slide driving wheel 145 is rotatably connected to the jig positioning plate 141. A driving wheel gear is provided at the end of the rotating shaft of the slide driving wheel 145, and a driving tooth is provided on the outer periphery of the jig driving disc 142. The driving wheel gear is engaged with the driving tooth on the jig driving disc 142, and rotating the slide driving wheel 145 can drive the jig driving disc 142 to rotate, thereby driving the multiple radial slides 143 to move synchronously on the jig positioning plate 141.

[0072] A slide locking device 146 is further provided in the peripheral region of the slide driving wheel 145, and the slide locking device 146 is threadedly connected with the slide driving wheel 145. A rotating handle is further provided at the end of the slide locking device 146, and the rotating handle can be conveniently rotated to rotate the slide locking device 146, so that the threaded shaft of the slide locking device 146 moves in the direction of the jig positioning plate 141 and abuts against the jig positioning plate 141 to lock the rotating position of the slide driving wheel 145 on the jig positioning plate 141, and finally lock the position of the support blocks 144 on the jig positioning plate 141, so that the large-diameter cylindrical workpiece is stably clamped on the inner support jig 14.

[0073] In some embodiments of the large-diameter cylindrical workpiece separable clamping drive device of this application, such as Figure 8 and Figure 9 As shown, a mounting base locking device 132 is also provided on the second mounting base 131. A simple mounting base locking device 132 is a handwheel with a screw. The screw of the handwheel passes through the bottom of the second mounting base 131 and is threadedly connected to a threaded sleeve fixed below the second mounting base 131. Rotating the handwheel causes the screw on the handwheel to move downward, with its end abutting against the transfer carriage body 11, locking the position of the second mounting base 131 on the transfer carriage body 11. Rotating the handwheel in the opposite direction causes the screw on the handwheel to move upward, away from the transfer carriage body 11, allowing the second mounting base 131 to move freely on the transfer carriage body 11. Of course, the mounting base locking device 132 can also use other existing locking devices.

[0074] As a specific embodiment of the large-diameter cylindrical workpiece separable clamping drive device of this application, such as Figure 8 and Figure 9 As described above, multiple casters 111 are provided under the transfer vehicle body 11, which support the transfer vehicle body 11 on the ground, allowing the transfer vehicle body 11 to move freely and easily on the ground.

[0075] Multiple lifting support legs 112 are also provided below the transport vehicle body 11. Various existing commercial products can be used for the lifting support legs 112. The lifting support legs 112 are equipped with an extension pedal and a retractable pedal. When the extension pedal is pressed, the lifting support leg 112 extends and supports the ground, causing the casters 111 to leave the ground. The transport vehicle body 11 is supported on the ground by the lifting support legs 112 and remains in the same position on the ground. When the retractable pedal is pressed, the lifting support leg 112 retracts and leaves the ground, causing the casters 111 to support the ground. The transport vehicle body 11 can move easily on the ground by means of the casters 111.
