Technical Field

[0001] The utility model relates to the field of spinning equipment, in particular to a servo core-pulling spinning machine. Background Art

[0002] Air conditioning refrigerant is usually stored in a liquid reservoir, and during the processing of the liquid reservoir, both ends of the liquid reservoir need to be spun on. The current liquid reservoir processing process is: spinning one end of the liquid reservoir close to the filter, installing the filter inside the liquid reservoir, cutting a groove on the outside of the liquid reservoir close to the filter, installing a baffle inside the liquid reservoir, cutting a groove on the outside of the liquid reservoir close to the baffle, and finally spinning one end of the liquid reservoir close to the baffle.

[0003] However, the current processing method has certain defects: ① Since the end close to the baffle is processed last, and foreign matter such as iron filings will be generated when chamfering and flattening the end surface after spinning, and a filter screen and a baffle have been installed in the middle of the liquid reservoir, the foreign matter inside the end close to the baffle cannot be cleaned by blowing; ② The end close to the baffle is used to connect the compressor, and the compressor is more sensitive to foreign matter, making it difficult to clean foreign matter, which increases the probability of damage to the compressor; ③ If the processing order of the two ends of the liquid reservoir in the current process is replaced, then during the spinning process of the end close to the filter screen, the core rod will move axially synchronously with the spinning wheel, so that the core rod will push the filter screen, thereby causing damage to the filter screen. Utility Model Content

[0004] The utility model aims to provide a servo core-pulling spinning machine which makes it easier to clean foreign matter generated during the spinning process of a workpiece and prevents the core rod from damaging parts inside the workpiece.

[0008] Furthermore, a chamfering cutter is provided on the second supporting plate, and the spinning wheel and the chamfering cutter are respectively placed on both sides of the core rod.

[0009] Furthermore, one end of the rotating spindle close to the core rod is provided with a clamping claw for clamping the workpiece.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0019] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0020] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0021] like Figure 1-4 The utility model provides a servo core-pulling spinning machine, including a workbench 1, a rotating spindle 2 arranged on the workbench 1, a mandrel seat 3 arranged on the workbench 1, and a spinning wheel 4 rotatably installed on the workbench 1. The mandrel seat 3 has a mandrel 5 built in it, and the mandrel 5 and the rotating spindle 2 are located on the same axis. The mandrel 5 can move axially relative to the mandrel seat 3, so that when the workpiece 6 rotates with the rotating spindle 2, the end of the mandrel 5 is inserted into the spinning position of the workpiece 6.

[0022] When it is necessary to spin one end of the workpiece close to the filter screen, the workpiece is placed on the rotating main shaft so that the workpiece can rotate with the rotating main shaft. At the same time, the mandrel seat drives the mandrel to move and penetrate into the inside of the position to be spun on the workpiece, and drives the spinning wheel close to the outside of the position to be spun on the workpiece. At this time, the spinning wheel pushes the end of the workpiece inward, and cooperates with the rotating main shaft to drive the workpiece to rotate, so that the workpiece can be spun stably. In the spinning process, the mandrel is axially moved relative to the mandrel seat, so that the mandrel can always be kept in the spinning position, and the situation in which the end of the mandrel pushes the filter screen is avoided.

[0023] Among them, one side of the rotating spindle is connected to the servo motor, and the rotation of the rotating spindle is controlled by the servo motor; the spinning wheel can rotate on its own, and after contacting the workpiece rotating with the rotating spindle, the spinning wheel can rotate along with the workpiece.

[0024] The workpiece 6 processed in this scheme is a liquid reservoir, and its two ends are respectively an A end 61 and a B end 62, wherein the B end 62 is used to connect the compressor, and a filter screen 63 and a baffle 64 are installed inside the liquid reservoir, the filter screen 63 is arranged close to the A end 61, and the baffle 64 is arranged close to the B end 62. Since this scheme adjusts the spinning sequence of the current process, the processing flow of this scheme is as follows:

[0025] Spin the B end 62 → install the baffle 64 inside the liquid reservoir → make a groove on the outside of the liquid reservoir near the baffle → install the filter 63 inside the liquid reservoir → make a groove on the outside of the liquid reservoir near the filter → finally spin the A end 61; (wherein, the initial spinning, installation of the baffle and filter, and groove making steps are performed manually or by other equipment, and are not described in detail in this solution)

[0026] Due to the improved processing flow of the present solution, after the B end 62 of the liquid storage device connected to the compressor is spun, the A end 61 has not yet been spun to the opening, so the B end 62 connected to the compressor can be cleaned of foreign matter by blowing.

[0027] It is worth mentioning that the core rod is pressed against the inner side of the workpiece spinning position, so that the inner hole size of the workpiece spinning position can be ensured by the core rod; at the same time, this solution can also be used in conjunction with an automatic loading rack, which is consistent with the existing loading equipment.

[0028] Preferably, a first track 7 parallel to the axis of the rotating spindle 2 is provided on the workbench 1, a first pallet 8 is movably installed on the first track 7, a second track 9 perpendicular to the axis of the rotating spindle 2 is provided on the first pallet 8, a second pallet 10 is movably installed on the second track 9, and the mandrel seat 3 is installed on the first pallet 8, and the spinning wheel 4 is arranged on the second pallet 10.

[0029] Specifically, the first support plate moves along the first track to drive the core rod and the spinning wheel to move along the axial direction of the rotating spindle, and the second support plate moves along the second track to drive the spinning wheel to move along the radial direction of the rotating spindle, so that the spinning wheel can stably spin the workpiece, and at the same time, it can also ensure the supporting effect of the core rod on the inner hole of the spinning position.

[0030] Among them, the first track and the second track are both controlled by a motor and a screw drive.

[0031] Preferably, the mandrel seat 3 has a built-in driving member 11, and one end of the mandrel 5 is connected to the output end of the driving member 11, so that the driving member 11 drives the mandrel 5 to move axially.

[0032] Specifically, since the mandrel will move synchronously with the spinning wheel, in order to prevent the mandrel from going too deep into the workpiece and causing the mandrel to push and damage the filter screen, the mandrel is controlled to move axially through a driving member so that the relative position between the mandrel and the workpiece can be relatively stable, ensuring that when the spinning wheel moves along the workpiece, the depth of the mandrel inserted into the workpiece can be maintained at the set value.

[0033] In one embodiment of the present scheme, after the mandrel moves to the set position inside the workpiece, the position of the mandrel and the spinning wheel at this time is used as the reference position. When the spinning wheel subsequently moves relative to the reference position, the mandrel performs reverse compensation relative to the reference position, so that the relative position of the mandrel and the workpiece remains unchanged when the spinning wheel moves.

[0034] Among them, the driving part adopts an electric cylinder.

[0035] Preferably, a chamfering cutter 12 is provided on the second support plate 10 , and the spinning wheel 4 and the chamfering cutter 12 are disposed on both sides of the core rod 5 .

[0036] Specifically, after the spinning is completed, the chamfering cutter is moved close to the spinning position of the workpiece through the movement and cooperation of the second support plate, and then the chamfering process is performed by the chamfering cutter. At the same time, since the core rod is located at the inner hole of the workpiece at this time, the core rod can be used to block foreign objects such as iron filings from entering the interior of the workpiece at the processing position.

[0037] Since the spinning wheel and the chamfering cutter are disposed on both sides of the core rod, the two directions in which the second support plate moves correspond to the spinning wheel and the chamfering cutter respectively, so that the two processing steps will not interfere with each other.

[0038] Preferably, the rotating spindle 2 has a clamping claw 13 at one end close to the core rod 5 for clamping the workpiece 6 so as to ensure that the workpiece is sufficiently stable during the spinning process.

[0039] Among them, the structure of the clamp is similar to that of the existing machine tool clamp, and will not be described in detail here.

[0040] Preferably, the end of the mandrel seat 3 has a guide sleeve 14 , and the mandrel 5 can move relative to the guide sleeve 14 .

[0041] Specifically, the axial movement of the core rod is guided and limited by the guide sleeve, thereby improving the dimensional stability of the inner hole at the spinning position of the workpiece.

[0042] Preferably, a bearing 15 is provided inside the guide sleeve 14, and the mandrel 5 is movably installed in the bearing 15 to improve the stability of the movement of the mandrel.

[0043] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
