The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, in the description of the present invention, "plurality" means two or more, unless otherwise expressly and specifically defined.

[0036] See Figure 1-4 , a machine tool for roller assembly provided in an embodiment of the present application, comprising: a frame 1, a roller shaft pushing assembly 2, and a steel pipe fixing assembly 3,

[0037] The frame 1 is provided with a V-shaped groove 11 for placing the roller shaft, and the V-shaped groove 11 extends along the X direction. The steel pipe fixing assembly 3 and the roller shaft pushing assembly 2 are respectively connected to the two ends of the frame 1 along the X direction;

[0038] The roller shaft pushing assembly 2 includes: a push block 21 and a first driving mechanism 22. The push block 21 is slidably connected to the V-shaped groove 11 of the frame 1. The first driving mechanism 22 is transmission-connected to the frame 1 and the push block 21. The first driving mechanism 22 is used to drive the push block 21 to move relative to the frame 1 along the V-shaped groove 11, so as to push the roller shaft located in the V-shaped groove 11 to move toward the steel pipe fixing assembly 3.

[0039] The steel pipe fixing assembly 3 includes: a second driving mechanism 31 and two groups of sliding assemblies 32. The two groups of sliding assemblies 32 are arranged on the frame 1 at intervals along the X direction. The sliding assembly 32 includes: a slide 321, a clamping mechanism 322, a lifting mechanism 323 and a steel pipe support frame 324. The slide 321 is slidably arranged on the frame 1. The second driving mechanism 31 is transmission-connected to the frame 1 and each of the slides 321, and is used to drive the two slides 321 to move toward or away from each other along the X direction. The clamping mechanism 322 and the lifting mechanism 323 are arranged on the slide 321 at intervals along the Y direction. The steel pipe support frame 324 is provided at the power output end of the lifting mechanism 323. The lifting mechanism 323 is used to drive the steel pipe support frame 324 to move along the Z direction. A fixing position for fixing the steel pipe is formed between the two clamping mechanisms 322.

[0040] In this embodiment, during actual operation, the two ends of the steel pipe are placed correspondingly on two steel pipe support frames 324 by a manipulator or other equipment, and the steel pipe support frames 324 are driven to move along the Z direction by the lifting mechanism 323, and the axis of the steel pipe is adjusted to be on the same horizontal line as the axis of the roller shaft in the V-shaped groove 11. Then, the two slides 321 are driven to move toward or away from each other along the X direction by the second driving mechanism 31, so that the two clamping mechanisms 322 provided on the slides 321 are correspondingly abutted against the two ends of the steel pipe, ensuring that the steel pipe does not shift during the assembly process. The roller shafts are placed correspondingly in the V-shaped groove 11 by a manipulator or other equipment, and the push block 21 is driven by the first driving mechanism 22 to push the roller shafts along the V-shaped groove 11 until the assembly of the roller shafts and the steel pipe is completed. By using this device, the roller assembly can be automated, which is more efficient and more accurate than manual assembly. In addition, by setting the V-shaped groove to widen the diameter of the roller shaft that can be placed, the device can be applied to roller shafts of multiple specifications, and when the push block pushes the roller shaft to move along the V-shaped groove, it can ensure that the axis of the roller shaft does not shift; a lifting mechanism is set to adjust the steel pipe support frame along the Z direction to adjust the axis position of the steel pipe placed thereon, and a clamping mechanism that can move along the X direction is set to fix steel pipes of different lengths, which facilitates the precise assembly of the roller shaft and the steel pipe, so that the device can be applied to the assembly of rollers of multiple specifications.

[0041] See Figure 6In addition, in some embodiments, the top of the steel pipe support frame 324 has a "V"-shaped support groove 3241. The present application preferably sets the cross-sectional shape of the V-shaped groove 11 to be V-shaped, and sets a "V"-shaped support groove 3241 on the top of the steel pipe support frame 324. On the one hand, this is to prevent the roller shaft and steel pipe from deviating during movement; on the other hand, the "V"-shaped cross-section helps widen the diameter of the steel pipe and roller shaft that can be placed, thereby accommodating the assembly of steel pipes and roller shafts of various specifications.

[0042] It is worth noting that in order to prevent multiple roller shafts from piling up in the V-groove 11 and affecting the shaft threading effect, the present application provides a beam switch (not shown in the drawings) at the connection between the V-groove 11 and the steel pipe fixing assembly 3. The beam switch consists of a transmitter and a receiver, and the transmitter and the receiver are respectively installed on both sides of the V-groove 11 along the Y direction. The beam switch is specifically based on the principle of light beam blocking detection to detect whether there is a roller shaft in the V-groove 11. The beam switch used in this application is a prior art and will not be described here.

[0043] See Figure 5 In some embodiments, the first drive mechanism 22 includes: a first motor 221, a gear 222, and a rack 223. The first motor 221 is provided on the push block 21, the gear 222 is provided at the output end of the first motor 221, the rack 223 is fixedly provided on the frame 1 along the X direction, and the rack 223 extends along the X direction. The gear 222 and the rack 223 are meshed and driven. The first motor 221 is used to drive the gear 222 to move along the rack 223 relative to the frame 1, thereby driving the push block 21 to move along the V-shaped groove 11 relative to the frame 1. In this embodiment, the first motor 221 drives the gear 222 to rotate, and the gear 222 meshes and drives the rack 223, thereby driving the gear 222 to move along the rack 223, causing the slider to move along the V-shaped groove 11, thereby driving the roller shaft in the groove to move. The design of the gear 222 and the rack 223 makes the transmission structure simple and effective, and convenient for subsequent maintenance.

[0044] See Figure 2In some embodiments, the clamping mechanism 322 includes a push plate 3221 and a first cylinder 3222. The first cylinder 3222 and the lifting mechanism 323 are spaced apart on the slide 321 along the Y direction. The push plates 3221 are located at the output end of the first cylinder 3222 and are used to drive the push plates 3221 to move along the X direction. The two push plates 3221 are each provided with an abutment position on their facing sides, and the two abutment positions define the fixed position. The second driving mechanism 31 drives the two slides 321 to move synchronously, so that the steel pipe support frames 324 provided on the slides 321 move closer to or further away from each other to accommodate the placement of steel pipes of different lengths. The first cylinder 3222 is then activated to drive the push plates 3221 to move along the X direction, so that the push plates 3221 abut against the end faces of the steel pipes, thereby securing the ends of the steel pipes and preventing them from moving during assembly, which would affect the assembly effect.

[0045] In some embodiments, the second driving mechanism 31 includes: a second motor 311 and a screw rod 312. The second motor 311 is arranged on the frame 1, and the screw rod 312 is arranged at the output end of the second motor 311. Two threaded segments are sequentially provided on the screw rod 312 along the X direction, and the thread rotation directions of the two threaded segments are opposite. The two slides 321 are respectively rotatably connected to one of the threaded segments.

[0046] In this embodiment, starting the second motor 311 can drive the screw 312 connected to its output end to rotate. Since the two threaded segments provided on the screw 312 have opposite thread rotation directions, the slides 321 connected to the two threaded segments can be synchronized and moved in opposite directions. This arrangement, on the one hand, can accurately control the relative spacing between the two slides 321. When the length of the steel pipe changes, the two slides 321 can adjust their positions synchronously. The push plate 3221 always clamps the steel pipe symmetrically from both ends, avoiding position deviation caused by unilateral drive, which may cause the steel pipe to fall off or loosen. On the other hand, there is no need to configure a motor for each of the two slides 321, which reduces the number of motors, control circuits and corresponding synchronous control programs. Complex synchronous reverse motion is achieved with a minimum of drive components, reducing the size and manufacturing cost of the equipment.

[0047] See Figure 3 In some embodiments, the screw rod 312 includes a first rod 3121 and a second rod 3122 connected in sequence along the X-direction. The first rod 3121 is disposed at the output end of the second motor 311, and the two threaded segments are disposed on the first rod 3121 and the second rod 3122, respectively. The two slides 321 are driven by independent rods. Compared to a design where a single rod drives two components, each rod bears less load, reducing the risk of bending and deformation and extending its service life.

[0048] See Figure 7 In some embodiments, the machine tool for assembling rollers further includes: a sensor 4, which is provided on the slide 321 away from the V-groove 11 and is used to detect whether a roller shaft abuts against the abutment position of the slide 321 away from the V-groove 11. Specifically, during the assembly of the rollers, after one end of the roller shaft passes through the steel pipe, the end face of the roller shaft abuts against the abutment position of the slide 321 away from the V-groove 11, and the sensor 4 immediately sounds an alarm, indicating that the assembly of the roller shaft and the steel pipe is complete. The assembled roller is then removed using a manipulator and the assembly of the next roller can begin. The provision of the sensor 4 can ensure the assembly accuracy of the roller shaft and the steel pipe.

[0049] See Figure 4 In order to facilitate loading, in some embodiments, the machine tool for roller assembly further includes: a roller shaft loading assembly 5,

[0050] The roller shaft feeding assembly 5 includes: a frame 51, a feeding platform 52, a third driving mechanism 53, a lifting mechanism 54 and a fourth driving mechanism. The frame 51 is fixed to one side of the frame 1 along the Y direction, and the feeding platform 52 and the lifting mechanism 54 are sequentially arranged on the frame 51 along the Y direction. The lifting mechanism 54 is closer to the frame 1 than the feeding platform 52, and the top surface of the lifting mechanism 54 is connected to the V-shaped groove 11. The third driving mechanism 53 is connected to the frame 51 and the feeding platform 52 for driving the feeding platform 52 to move along the Z direction so that the roller shaft located in the feeding platform 52 moves toward the lifting mechanism 54. The fourth driving mechanism is connected to the frame 51 and the lifting mechanism 54 for driving the lifting mechanism 54 to move along the Z direction so that the roller shaft located on the lifting mechanism 54 moves toward the V-shaped groove 11.

[0051] In this embodiment, when in use, a plurality of roller shafts are placed on the loading platform 52 at one time by a manipulator, and the third drive mechanism 53 is started to drive the loading platform 52 to move along the Y direction until its top surface is flush with the lifting mechanism 54, so that the roller shafts on the loading platform 52 move to the lifting mechanism 54, and then the fourth drive mechanism is started to drive the lifting mechanism 54 to move along the Y direction until its top surface is flush with the top surface of the V-shaped groove 11, so that the roller shafts on the lifting mechanism 54 move into the V-shaped groove 11, completing the loading work. It is worth noting that in order to increase the loading speed, the top surfaces of the loading platform 52 and the lifting mechanism 54 in this application are gradually tilted downward from the side away from the frame 1 to the side close to the frame 1 to speed up the movement speed of the roller shafts.

[0052] See Figure 8In order to ensure that only one roller shaft is transported into the V-shaped groove 11 at a time, in some embodiments, the lifting mechanism 54 includes: a first lifting plate 541, a second lifting plate 542 and a third lifting plate 543, the first lifting plate 541, the second lifting plate 542 and the third lifting plate 543 are sequentially arranged on the frame 51 along the Y direction, the third lifting plate 543 is closer to the frame 1 than the first lifting plate 541, and the top surface of the third lifting plate 543 is in contact with the V-shaped groove 11, the fourth driving mechanism transmission The frame 51 is connected with the first lifting plate 541, the second lifting plate 542, and the third lifting plate 543, and is used to drive the first lifting plate 541, the second lifting plate 542, and the third lifting plate 543 to move along the Z direction, wherein the first lifting plate 541 and the third lifting plate 543 move synchronously and in the opposite direction of movement of the second lifting plate 542, so that the roller shaft located on the first lifting plate 541 moves to the second lifting plate 542, the third lifting plate 543, and the V-groove 11 in sequence.

[0053] In this embodiment, the fourth driving mechanism drives the first lifting plate 541 and the third lifting plate 543 to move synchronously, and drives the second lifting plate 542 to move in the opposite direction of the above-mentioned two lifting plates. The height difference of the three lifting plates is combined with the rolling characteristics of the roller shaft to form a "step-by-step blocking and release" mechanism. The gravity of the roller shaft itself is used to ensure that only the frontmost roller shaft can pass through the three lifting plates and enter the V-groove 11, and the remaining roller shafts are blocked by the rear lifting plate. Specifically, the first step: when the first roller shaft at the front end rolls to the position of the first lifting plate 541, the second lifting plate 542 remains in a low position (parallel to the loading platform 52), and the first and third lifting plates 543 are synchronously raised to a high position (higher than 1 / 2 of the diameter of the roller shaft), so that the first shaft rolls onto the second lifting plate 542; the second step: the first and third lifting plates 543 are synchronously lowered to a low position (parallel to the loading platform 52), and the second lifting plate 542 is raised to a high position (higher than 1 / 2 of the diameter of the roller shaft), so that the first shaft rolls onto the third lifting plate 543, and the second shaft rolls onto the first lifting plate 541 at the same time; the third step: the first and third lifting plates 543 are synchronously raised to a high position (higher than 1 / 2 of the diameter of the roller shaft), and the second lifting plate 542 is lowered to a low position (parallel to the loading platform 52), so that the first shaft rolls into the V-groove 11, and the second shaft rolls onto the second lifting plate 542. By repeating the above steps, only one roller shaft can be conveyed into the V-shaped groove 11 each time.

[0054] In some embodiments, the roller shaft loading assembly 5 further includes a baffle 55, which is disposed at one end of the loading platform 52 along the X direction and is used to block the roller shaft placed on the loading platform 52 to prevent it from falling. During the loading process, the baffle 55 can prevent the roller shaft from lateral deviation, ensuring that it moves along the predetermined path.

[0055] In summary, the machine tool for roller assembly provided in this embodiment can be applied to the assembly of steel pipes and roller shafts of different specifications, and can ensure assembly accuracy, improve assembly efficiency, fully automate operation, and have high safety.
