Description

Technical Field

[0001] The invention relates to a pipe clamping device for a casing machine and belongs to the field of casing machine equipment. Background Art

[0002] Electronic transformers are traditional electronic components. Due to safety regulations and insulation requirements, many products need to be sleeved at the beginning and end of winding. The tube clamping device is the core functional part of the sleeve machine. It uses two upper and lower clamps to clamp the sleeve so that the copper wire can pass through to complete the subsequent winding function. The current tube clamping mechanism on the market basically relies on double cylinders to push and merge. It is very difficult to adjust the center of the merged position to be consistent with the guide needle position of the copper wire. Not only does the part require very high processing skills, but also position offsets often occur during the actual machine adjustment process. The original technology controls the opening and closing of the clamp by opening and closing the upper and lower cylinders, and controls the opening and closing positions by limiting. The accuracy of opening and closing cannot be guaranteed and only three position points can be adjusted. Summary of the invention

[0003] The present invention aims to provide a tube clamping device for a casing machine, which controls the closing of a clamp by controlling the rotation of a center adjustment block controlled by a servo motor, can ensure that the opening and closing of an upper clamp and a lower clamp are synchronized each time, and can be adjusted to any position. Since a machine screw hole for fixing the center adjustment block is provided on the center adjustment block, the machine screw can be locked after adjusting to the center position to ensure that the center position of the clamp does not change. After the two clamps are closed, the center position of the clamp is controlled to be consistent with the positioning center hole by tightly fitting the center adjustment block up and down.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

The opening and closing of the upper clamp and the lower clamp are adjusted by adjusting the position of the center adjustment block. Since a machine screw hole for fixing the center adjustment block is provided on the center adjustment block, the machine screw can be locked after adjusting to the center position to ensure that the center position of the clamp does not change. After the two clamps are closed, the center position of the clamp is controlled to be consistent with the positioning center hole by tightly fitting the center adjustment block up and down. Compared with the original technology of relying on naked eye observation to see whether the center of the guide needle is aligned, the accuracy is greatly improved, it is easy to use and saves time.

[0006] Furthermore, the cross-section of the center adjustment block is set to be fan-shaped, the center adjustment block is fixedly connected to the threaded rod by threaded connection, a threaded rod fixing hole is provided on the side of the center adjustment block, and the machine screw hole is set on the wider side of the center adjustment block.

[0007] Furthermore, a positioning center hole is provided between the upper clamp and the lower clamp.

[0008] Furthermore, an adjustment ring is provided on the outside of the positioning center hole, and the adjustment ring is connected to the mounting ring. The bottom and top of the adjustment ring are fixedly connected with connecting plates, and the connecting plates are provided with connecting threaded holes. The left and right sides of the mounting ring are fixedly connected with connecting blocks.

[0009] Furthermore, the bottom of the base is movably connected to a transverse guide rail via a first sliding block, the top of the base is fixedly connected to a longitudinal guide rail, the top of the longitudinal guide rail is fixedly connected to a servo motor via a motor support, the output end of the servo motor is fixedly connected to a threaded rod, the bottom of the threaded rod is threadedly connected to a center adjustment block, the rightmost end of the transverse guide rail is fixedly connected to a first limit seat, and the base is also slidably connected to a transverse slider, and the closing of the clamp is controlled by the rotation of the central adjustment block controlled by the servo motor, which can ensure that the opening and closing of the upper and lower clamps are synchronized each time and can be adjusted to any position.

[0010] Furthermore, a driving cylinder is provided on one side of the first limiting seat, an output end of the driving cylinder is fixedly connected to a transverse slider, and the transverse slider is driven by the driving cylinder to be slidably connected to the base.

[0011] Furthermore, limit blocks are provided on both sides of the transverse slider, and the limit blocks are used to limit the movement stroke of the transverse slider.

[0012] Furthermore, the top and bottom ends of the longitudinal guide rail are respectively fixedly connected to the second limit seat and the third limit seat, the longitudinal guide rail is slidably connected to the first vertical slider and the second vertical slider, the upper clamp and the lower clamp are respectively fixedly connected to the first vertical slider and the second vertical slider, a guide rod is fixedly connected between the longitudinal guide rail and the base, the upper clamp and the lower clamp are both slidably connected to the guide rod, and the spring is sleeved on the guide rod.

[0013] Furthermore, the spring sleeve is arranged between the upper clamp and the second limit seat, and between the lower clamp and the third limit seat, and can play a buffering role when the first vertical slider and the second vertical slider move.

[0014] Furthermore, a driving cylinder is provided on one side of the first limiting seat, an output end of the driving cylinder is fixedly connected to a transverse slider, and the transverse slider is driven by the driving cylinder to be slidably connected to the base.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The threaded rod connected to the servo motor is rotated in the up and down directions to drive the center adjustment block to rotate, and the two clamps are supported by springs at the top and bottom. The opening and closing of the two clamps are adjusted by adjusting the position of the center adjustment block. Since there is a screw hole for locking the machine rice on the center adjustment block, the machine rice can be locked after adjusting to the center position to ensure that the center position of the clamp will not change. Since the center position of the clamp is locked on the threaded rod, the center position of the clamp can be controlled to be consistent with the center of the guide needle by closing the two clamps and closely fitting the center adjustment block up and down. Compared with the original technology of observing whether the center of the guide needle is aligned with the naked eye, the accuracy is greatly improved and time is saved. The closure of the clamp is controlled by the rotation of the central adjustment block controlled by the servo motor, which can ensure that the opening and closing of the upper and lower clamps are synchronized every time, and can be adjusted to any position. Compared with the original technology, which controls the opening and closing of the clamp by the opening and closing of the upper and lower cylinders, and controls the opening and closing positions by limiting, the accuracy of opening and closing cannot be guaranteed and only three position points can be adjusted. It has good versatility. The original technology needs to replace a new clamp when changing a product, while the present invention can be shared by products of different diameters;

[0017] 2. As for the positioning center hole, the size of the positioning center hole aperture can be adjusted according to products of different diameters to better adapt to the passage of the casing and facilitate the connection between the copper wire and the casing. When the diameter of the product casing is large, the servo motor drives the threaded rod to rotate the wider side of the center adjustment block to between the upper clamp and the lower clamp, and the distance between the upper clamp and the lower clamp is increased. The bolts that fix the adjustment clamp are removed from the connecting threaded holes, so as to expand the aperture adjustment of the positioning center hole to adapt to the casing. When the diameter of the product casing is small, the adjustment clamp is fixedly installed on the mounting ring to facilitate the connection between the casing with a smaller diameter and the copper wire, and to facilitate the positioning adjustment of the fixture.

[0018] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention is further described below in conjunction with specific embodiments, wherein the accompanying drawings are only used for exemplary descriptions and represent only schematic diagrams rather than actual drawings, and should not be understood as limitations on this patent. In order to better illustrate the specific embodiments of the present invention, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted. Based on the specific embodiments of the present invention, all other specific embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figure 1-5As shown, a tube clamping device for a casing machine includes a base 2, a center adjustment block 9, a clamp, a servo motor 6, and a positioning center hole 20. The clamp is composed of an upper clamp 10 and a lower clamp 11. The threaded rod 8 connected to the servo motor 6 is rotated to drive the rotation of the center adjustment block 9. The upper clamp 10 and the lower clamp 11 are supported by springs 7 from top to bottom. The opening and closing of the upper clamp 10 and the lower clamp 11 are adjusted by adjusting the position of the center adjustment block 9. Since a machine screw hole 23 for fixing the center adjustment block 8 is provided on the center adjustment block 9, the machine screw can be locked after adjusting to the center position to ensure that the center position of the clamp will not change. The center position of the clamp is controlled to be consistent with the positioning center hole by closing the two clamps and closely fitting the center adjustment block 9 from top to bottom. Compared with the original technology of observing whether the center of the guide needle is aligned with the naked eye, the accuracy is greatly improved, which is convenient to use and saves time.

[0030] In this embodiment, the cross-section of the center adjustment block 9 is set to be fan-shaped, and the center adjustment block 9 is fixedly connected to the threaded rod 8 by a threaded connection. A threaded rod fixing hole 22 is provided on the side of the center adjustment block 9, and the machine screw hole 23 is set on the wider side of the center adjustment block 9.

[0031] Since the center adjustment block 9 is set as a vertical fan-shaped structure, when the servo motor 6 drives the center adjustment block 9 to rotate clockwise, the distance between the upper clamp 10 and the lower clamp 11 is gradually increased, so that the larger diameter sleeve can be positioned, and the center position of the center adjustment block 9 is installed at the center position between the upper clamp 10 and the lower clamp 11. When in use, the center of the guide needle is ensured to be at the center position of the positioning center hole 20. In this case, since the opening and closing of the upper clamp 10 and the lower clamp 11 are synchronized each time and can be adjusted to any position, the center position of the clamp is ensured not to change, which is convenient for the sleeve connection between the sleeve and the copper wire.

[0032] In this embodiment, a positioning center hole 20 is provided between the upper clamp 10 and the lower clamp 11 .

[0033] After the fixture has completed the center positioning of the sleeve and the guide pin, it can effectively ensure that the sleeve and the copper wire can correctly enter the positioning center hole 20, so that the next station of processing can be quickly carried out.

[0034] In this embodiment, the bottom of the base 2 is movably connected to a transverse guide rail 1 through a first sliding block 3, the top of the base 2 is fixedly connected to a longitudinal guide rail 4, the top of the longitudinal guide rail 4 is fixedly connected to a servo motor 6 through a motor support 5, the output end of the servo motor 6 is fixedly connected to a threaded rod 8, the bottom of the threaded rod 8 is threadedly connected to a center adjustment block 9, the rightmost end of the transverse guide rail 1 is fixedly connected to a first limit seat 18, and the base 2 is also slidably connected to a transverse slider 16. The rotation of the center adjustment block 9 is controlled by the servo motor 6 to control the closing of the clamp, which can ensure that the opening and closing of the upper clamp 10 and the lower clamp 11 are synchronized each time and can be adjusted to any position.

[0035] In this embodiment, a driving cylinder 17 is provided on one side of the first limiting seat 18 , and an output end of the driving cylinder 17 is fixedly connected to a transverse slider 16 , and the transverse slider 16 is driven by the driving cylinder 17 to be slidably connected to the base 2 .

[0036] The transverse slider 16 is used to transport the raw materials required for the next processing station. The transverse slider 16 is driven by the driving cylinder 17 to transport the raw materials, and the movement stroke of the transverse slider 16 is limited by the limit block.

[0037] In this embodiment, limit blocks are provided on both sides of the transverse slider 16 , and the limit blocks are used to limit the movement stroke of the transverse slider 16 .

[0038] In this embodiment, the top and bottom ends of the longitudinal guide rail 4 are respectively fixedly connected with the second limit seat 15 and the third limit seat 21, the longitudinal guide rail 4 is slidably connected with the first vertical slider 12 and the second vertical slider 14, the upper clamp 10 and the lower clamp 11 are respectively fixedly connected to the first vertical slider 12 and the second vertical slider 14, a guide rod 19 is fixedly connected between the longitudinal guide rail 4 and the base 2, the upper clamp 10 and the lower clamp 11 are both slidably connected to the guide rod 19, and the spring 7 is sleeved on the guide rod 19.

[0039] In this embodiment, the spring 7 is sleeved between the upper clamp 10 and the second limit seat 15 and between the lower clamp 11 and the third limit seat 21 , and can play a buffering role when the first vertical slider 12 and the second vertical slider 14 move.

[0040] The upper clamp 10 and the lower clamp 11 are driven to move by the first vertical slider 12 and the second vertical slider 14 respectively. During the movement of the first vertical slider 12 and the second vertical slider 14 along the guide rod 19, the spring 7 plays a buffering role on the one hand, and on the other hand, can play a good corrective role when the upper clamp 10 and the lower clamp 11 are reset. The clamping of the sleeve can be automatically reset, which is more convenient to use.

[0041] In this embodiment, a driving cylinder 17 is provided on one side of the first limiting seat 18 , and an output end of the driving cylinder 17 is fixedly connected to a transverse slider 16 , and the transverse slider 16 is driven by the driving cylinder 17 to be slidably connected to the base 2 .

[0042] By adopting the above technical solution: the center position of the clamp can be controlled to be consistent with the center of the guide needle by closing the two clamps and closely fitting the center adjustment block 9 up and down, so that the sleeve and the copper wire can enter the positioning center hole 20 for processing at the next workstation. Compared with the original technology of relying on naked eye observation to check whether the center of the guide needle is aligned, the accuracy is greatly improved and time is saved.

[0044] like Figure 1-6 As shown, a tube clamping device for a casing machine includes a base 2, a center adjustment block 9, a clamp, a servo motor 6, and a positioning center hole 20. The clamp is composed of an upper clamp 10 and a lower clamp 11. The threaded rod 8 connected to the servo motor 6 is rotated to drive the rotation of the center adjustment block 9. The upper clamp 10 and the lower clamp 11 are supported by springs 7 from top to bottom. The opening and closing of the upper clamp 10 and the lower clamp 11 are adjusted by adjusting the position of the center adjustment block 9. Since a machine screw hole 23 for fixing the center adjustment block 8 is provided on the center adjustment block 9, the machine screw can be locked after adjusting to the center position to ensure that the center position of the clamp will not change. The center position of the clamp is controlled to be consistent with the positioning center hole by closing the two clamps and closely fitting the center adjustment block 9 from top to bottom. Compared with the original technology of observing whether the center of the guide needle is aligned with the naked eye, the accuracy is greatly improved, which is convenient to use and saves time.

[0045] In this embodiment, the cross-section of the center adjustment block 9 is set to be fan-shaped, and the center adjustment block 9 is fixedly connected to the threaded rod 8 by a threaded connection. A threaded rod fixing hole 22 is provided on the side of the center adjustment block 9, and the machine screw hole 23 is set on the wider side of the center adjustment block 9.

[0046] In this embodiment, a positioning center hole 20 is provided between the upper clamp 10 and the lower clamp 11 .

[0047] In this embodiment, an adjustment snap ring 25 is provided on the outer side of the positioning center hole 20, and the adjustment snap ring 25 is connected to the mounting ring 24. The bottom and top of the adjustment snap ring 25 are fixedly connected with connecting plates 27, and the connecting plate 27 is provided with a connecting threaded hole 13. The mounting ring 24 is fixedly connected with a clamping block 26 on both the left and right sides.

[0048] Among them, the clamping block 26 is used to fix the mounting ring 24 to the longitudinal guide rail 4, a connecting threaded hole 13 is opened on the connecting piece 27 on the adjusting clamp 25, and a threaded hole matching the connecting threaded hole 13 is provided at the corresponding position on the mounting ring 24. The connecting threaded hole 13 is connected to the mounting ring 24 by bolts. The adjusting clamp 25 can be set to multiple different thicknesses according to actual production needs. When adjusting the distance between the upper clamp 10 and the lower clamp 11, different adjusting clamps 25 can be selected for replacement according to actual needs, so as to facilitate the positioning of the center hole 20 to guide the sleeve.

[0049] In this embodiment, the bottom of the base 2 is movably connected to a transverse guide rail 1 through a first sliding block 3, the top of the base 2 is fixedly connected to a longitudinal guide rail 4, the top of the longitudinal guide rail 4 is fixedly connected to a servo motor 6 through a motor support 5, the output end of the servo motor 6 is fixedly connected to a threaded rod 8, the bottom of the threaded rod 8 is threadedly connected to a center adjustment block 9, the rightmost end of the transverse guide rail 1 is fixedly connected to a first limit seat 18, and the base 2 is also slidably connected to a transverse slider 16. The rotation of the center adjustment block 9 is controlled by the servo motor 6 to control the closing of the clamp, which can ensure that the opening and closing of the upper clamp 10 and the lower clamp 11 are synchronized each time and can be adjusted to any position.

[0050] The servo motor 6 drives the center adjustment block 9 to rotate forward and reverse. The vertically arranged fan-shaped block will adjust the distance between the upper clamp 10 and the lower clamp 11 during the rotation, thereby making the adjustment range of the clamp larger. Under the action of the spring 7, the upper clamp 10 and the lower clamp 11 can be automatically reset, which is more convenient to use.

[0051] In this embodiment, a driving cylinder 17 is provided on one side of the first limiting seat 18 , and an output end of the driving cylinder 17 is fixedly connected to a transverse slider 16 , and the transverse slider 16 is driven by the driving cylinder 17 to be slidably connected to the base 2 .

[0052] In this embodiment, limit blocks are provided on both sides of the transverse slider 16 , and the limit blocks are used to limit the movement stroke of the transverse slider 16 .

[0053] In this embodiment, the top and bottom ends of the longitudinal guide rail 4 are respectively fixedly connected with the second limit seat 15 and the third limit seat 21, the longitudinal guide rail 4 is slidably connected with the first vertical slider 12 and the second vertical slider 14, the upper clamp 10 and the lower clamp 11 are respectively fixedly connected to the first vertical slider 12 and the second vertical slider 14, a guide rod 19 is fixedly connected between the longitudinal guide rail 4 and the base 2, the upper clamp 10 and the lower clamp 11 are both slidably connected to the guide rod 19, and the spring 7 is sleeved on the guide rod 19.

[0054] The upper clamp 10 and the lower clamp 11 are driven to move by the first vertical slider 12 and the second vertical slider 14 respectively. During the movement of the first vertical slider 12 and the second vertical slider 14 along the guide rod 19, the spring 7 plays a buffering role on the one hand, and on the other hand, can play a good corrective role when the upper clamp 10 and the lower clamp 11 are reset. The clamping of the sleeve can be automatically reset, which is more convenient to use.

[0055] In this embodiment, the spring 7 is sleeved between the upper clamp 10 and the second limit seat 15 and between the lower clamp 11 and the third limit seat 21 , and can play a buffering role when the first vertical slider 12 and the second vertical slider 14 move.

[0057] By adopting the above technical solution: controlling the rotation of the center adjustment block 9 through the servo motor 6 to control the closing of the clamp, it can ensure that the opening and closing of the upper clamp 10 and the lower clamp 11 are synchronized every time, and can be adjusted to any position without the need to observe with the naked eye or adjust manually. When adjusting the distance between the upper clamp 10 and the lower clamp 11, different adjustment clamps 25 can be selected for replacement according to actual needs, which is convenient for positioning the center hole 20 to guide the sleeve, and the clamp is more versatile.

[0058] It should be noted that the present invention is a tube clamping device for a casing machine. When in use, the rotation of the center adjustment block 9 is controlled by the servo motor 6 to control the closing of the clamp, which can ensure that the opening and closing of the upper clamp 10 and the lower clamp 11 are synchronized each time and can be adjusted to any position. Since a machine screw hole 23 for fixing the center adjustment block 8 is provided on the center adjustment block 9, the machine screw can be locked after adjusting to the center position to ensure that the center position of the clamp does not change. After the two clamps are closed, the center adjustment block 9 is tightly fitted up and down to control the center position of the clamp to be consistent with the positioning center hole. Compared with the original technology of observing whether the center of the guide needle is aligned with the naked eye, the accuracy is greatly improved, it is easy to use, saves time, and can improve processing efficiency. When adjusting the distance between the upper clamp 10 and the lower clamp 11, different adjustment clamps 25 can be selected for replacement according to actual needs, which is convenient for positioning the center hole 20 to guide the casing. It has good versatility and can be shared by products of different diameters.

[0059] Compared with the prior art, the present invention has the following beneficial effects:

[0060] 1. The threaded rod 8 connected to the servo motor 6 is rotated in the up and down directions to drive the center adjustment block 9 to rotate, and the two clamps are supported by springs 7 at the top and bottom. The opening and closing of the two clamps are adjusted by adjusting the position of the center adjustment block 9. Since there is a screw hole for locking the machine rice on the center adjustment block 9, the machine rice can be locked after adjusting to the center position to ensure that the center position of the clamp will not change. Since the center position of the clamp is locked on the threaded rod 8, the center position of the clamp can be controlled to be consistent with the center of the guide needle by closing the two clamps and closely fitting the center adjustment block 9 up and down. Compared with the original technology that relies on naked eye observation, Checking whether the center of the guide needle is aligned greatly improves the accuracy and saves time. The servo motor 6 controls the rotation of the central adjustment block 9 to control the closing of the clamp, which can ensure that the opening and closing of the upper and lower clamps are synchronized every time, and can be adjusted to any position. Compared with the original technology, the opening and closing of the clamp is controlled by the opening and closing of the upper and lower cylinders, and the opening position and the closing position are controlled by the limit. The accuracy of opening and closing cannot be guaranteed and only three position points can be adjusted. It has good versatility. The original technology needs to replace a new clamp when changing a product, while the present invention can be shared by products of different diameters;

[0061] 2. As for the positioning center hole 20, the size of the positioning center hole diameter can be adjusted according to products of different diameters to better adapt to the passage of the sleeve and facilitate the connection between the copper wire and the sleeve. When the diameter of the product sleeve is large, the servo motor 6 drives the threaded rod 8 to rotate the wider side of the center adjustment block 9 to between the upper clamp 10 and the lower clamp 11, and the distance between the upper clamp 10 and the lower clamp 11 is increased. The bolts for fixing the adjustment clamp 25 are removed from the connecting threaded hole 13, thereby adjusting the aperture of the positioning center hole 20 to expand and adapt to the sleeve. When the diameter of the product sleeve is small, the adjustment clamp 25 is fixedly installed on the mounting ring 24 to facilitate the connection between the sleeve with a smaller diameter and the copper wire, and to facilitate the positioning and adjustment of the fixture.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrating the principles of the present invention.
