Description

Technical Field

[0001] The present invention relates to the technical field of machining, and particularly to a processing tooling and a processing method for a roll core. Background Art

[0002] The raw foil machine is an important device for producing products such as lithium battery copper foil. Due to conditions such as special structures, weights, and corrosion environments in industries such as lithium battery copper foil, the core component of the product in the raw foil machine, the cathode roll (i.e., the roll core), is designed as a large-diameter roll workpiece, and the maximum outer diameter dimension of this workpiece is usually about 2.7 meters in diameter.

[0003] Since the roll core workpiece has a large diameter size, a high width, and long shafts at both ends, it is difficult to clamp the workpiece during vertical lathe machining, and the reference of the lower half shaft end cannot be corrected and centered. Therefore, the vertical lathe machining of the roll core has always been a difficult point in machining. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides a new technical solution, that is, a processing tooling dedicated to this type of roll core is provided, and the roll core is positioned and fixed through this processing tooling, thereby facilitating subsequent turning machining.

[0005] Specifically, the detailed technical solution provided by the present invention is as follows:

[0008] A clamping assembly, the threaded shaft end of the roll core is connected to the mounting seat through the clamping assembly; the clamping assembly is coaxially arranged with the mounting seat and is installed in the hollow structure; the clamping assembly is simultaneously configured to be adjustable and movable along the first axis in the hollow structure.

[0009] Further, the clamping assembly includes a positioning body, and the positioning body is configured to be tightly abutted against the threaded shaft end of the roll core to guide the installation of the threaded shaft end of the roll core into the mounting seat.

[0010] Further, the positioning body is composed of a plurality of lobes, and the plurality of lobes are spliced end to end to form a positioning body having a central axis.

[0011] Further, the outer side surface of each lobe has a locking port, and a locking ring is used to cooperate with each locking port to imprison and thus fix the lobe on the outer circular surface of the roll core.

[0012] Further, three lobes are provided.

[0013] Further, the clamping assembly further includes a transition sleeve, which is sleeved on the positioning body; the transition sleeve is connected in the hollow structure of the mounting seat; the transition sleeve is movably connected to the mounting seat, so that the transition sleeve can be adjusted and moved along the first axis.

[0015] Further, the transition sleeve has an inclined inner surface, and the positioning body has an outer surface corresponding to the inner surface; when the inner surface is attached to the outer surface, the positioning body moves relative to the transition sleeve along the first axis to achieve clamping or loosening.

[0016] Further, a lifting eye screw is installed and connected to the threaded shaft end of the roll core. The lifting eye screw passes through a process round bar in the middle, and pressing plates are pressed at both ends of the process round bar to press the roll core tightly on the mounting seat.

[0032] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0033] This embodiment provides a roll core processing tooling, through which the clamping and positioning of roll core type workpieces are realized, and a calibration and centering reference during clamping is provided, so as to ensure the geometric tolerance accuracy of workpiece turning processing.

[0034] Specifically, referring to Figure 1 - Figure 6 , the tooling of this solution includes a mounting seat 10, and the mounting seat 10 has a cylindrical hollow structure; at the same time, the mounting seat 10 has a first axis A; a clamping assembly is installed in the mounting seat 10. Specifically, the threaded shaft end 101 of the roll core 100 is connected to the mounting seat 10 through the clamping assembly; the clamping assembly is coaxially arranged with the mounting seat 10 and is installed in the hollow structure; the clamping assembly is also configured to be adjustable and movable along the first axis A in the hollow structure.

[0035] It can be understood that in order to achieve the clamping and positioning of the roll core, it is realized by setting the clamping assembly and utilizing the connection and cooperation between the clamping assembly and the mounting base 10. At the same time, considering that roll core parts have different specifications, the clamping assembly is designed to be adjustable and movable along the axis (the first axis A) in the mounting base 10. In the specific operation process, the position of the clamping assembly in the mounting base 10 is adjusted according to the actual length of the roll core to ensure that the tooling of this solution can adapt to a variety of roll core workpieces.

[0036] In this solution, the clamping assembly includes a positioning body 20, which is configured to be tightly abutted against the threaded shaft end 101 of the roll core 100. By using the positioning body 20 here, the threaded shaft end 101 of the roll core 100 is guided to be installed into the mounting base 10. Specifically, the positioning body 20 in this solution is composed of multiple lobes, and the multiple lobes are spliced end to end to form a positioning body 20 with a central axis.

[0037] By designing the positioning body 20 as a split lobe structure, the positioning body 20 can be more conveniently installed and fixed with the roll core 100. Compared with the positioning body of an integral structure, this solution has certain advantages in terms of convenience and operability.

[0038] In order to ensure that the multiple lobes can be stably fixed when installed with the roll core 100, in the specific embodiment of this solution, the outer side surface of each lobe has a locking port 21, and a lock ring (not shown) is used to cooperate with each locking port to imprison and thus fix the lobe on the outer cylindrical surface of the roll core 100.

[0039] In this solution, there are three lobes; the three lobes are arranged around the roll core 100 and cooperate with each other to achieve the function of the positioning body 20.

[0040] The clamping assembly further includes a transition sleeve 30, which is sleeved on the positioning body 20; the transition sleeve 30 is connected in the hollow structure of the mounting base 10; the transition sleeve 30 is movably connected to the mounting base 10, so that the transition sleeve 30 can be adjusted and moved along the first axis A.

[0041] The movement between the transition sleeve 30 and the mounting base 10 here is realized in a spiral manner. Specifically, an internal thread is provided on the inner wall of the inner cylinder of the mounting base 10, and an external thread is provided on the outer surface of the transition sleeve 30; the transition sleeve 30 and the mounting base 10 are movably connected in a screwed manner.

[0042] That is, the operator can reasonably adjust the position of the transition sleeve 30 in the mounting base 10 according to the actual length of the roll core 100, which is realized in a spiral rotation manner, simple, convenient and fast.

[0043] Optionally, when the transition sleeve 30 has an inclined inner surface 31 and the positioning body 20 has an outer surface 22 corresponding to the inner surface 31, when the inner surface 31 fits with the outer surface 22, the positioning body 20 moves along the first axis A relative to the transition sleeve 30 to achieve clamping or loosening.

[0044] The positioning body 20 and the transition sleeve 30 are matched in the form of inclined surfaces (the inclined inner surface and the inclined outer surface). During the clamping and positioning process, the cooperation between the inner surface and the outer surface will further clamp the roller core by the positioning body 20, effectively reducing the possibility of the roller core loosening relative to the positioning body 20.

[0045] After the above operations are completed, we also install a connecting lifting eye bolt 40 at the threaded shaft end 101 of the roller core 100, and a process round bar 41 passes through the middle of the lifting eye bolt 40. Press plates (not shown) are installed at both ends of the process round bar 41, which can realize pressing the roller core 100 on the mounting seat 10.

[0046] By using the above tooling to complete the installation and positioning of the roller core workpiece, the geometric tolerance accuracy of the workpiece turning can be effectively guaranteed.

[0047] For the above processing tooling, a processing method for roller core workpieces using the tooling is also provided here, that is, a processing method for a roller core, which is processed using the above-mentioned tooling, and specifically includes the following steps.

[0048] S1. Turn the threaded shaft end 101 of the roller core 100 downward, evenly distribute the three segments on the reference outer circle of the threaded shaft end 101 of the roller core 100 and fix them with a locking ring.

[0049] S2. Fix the mounting seat 10 to the lathe faceplate (not shown), align and fix it with the faceplate based on the outer cylindrical wall of the mounting seat 10, so that the first axis A of the mounting seat 10 is coaxial with the central axis of the faceplate.

[0050] S3. Install the transition sleeve 30 into the hollow structure of the mounting seat 10, and adjust the relative position of the transition sleeve 30 in the mounting seat 10 according to the actual length of the roller core 100.

[0051] S4. Adjust and move the roller core so that the positioning body fixed on the roller core is sleeved into the transition sleeve, and the inner surface of the positioning body fits with the inner surface of the transition sleeve.

[0052] S5. Install a lifting eye bolt 40 at the threaded shaft end of the roller core 100. A process round bar 41 passes through the middle of the lifting eye bolt 40, and press plates are connected to both ends of the process round bar 41, thereby realizing tightening the roller core 100 on the mounting seat 10.

[0053] This technical solution clamps and positions the roll core workpiece through a tooling, provides a calibration and centering reference during clamping, and ensures the geometric tolerance accuracy of the workpiece during turning processing; thereby facilitating the processing of roll core workpieces by operators.
