Description

Technical Field

[0001] This utility model relates to the field of copper processing technology, and in particular to a copper processing sleeve grinding device. Background Technology

[0002] Currently in the copper processing industry, the coiler of copper foil rolling mills generally adopts a double-cone clamping method, with a steel sleeve between the two cones, used for winding and unwinding copper strip foil.

[0003] The tapered holes at both ends of the steel sleeve are precisely matched with the double-tapered clamping device. After long-term use, they will deform to a certain extent, which will increase the coaxiality error between the tapered holes at both ends and the outer circle, affecting the plate shape quality of the copper strip foil winding.

[0004] Deformation of the steel sleeve affects the quality of the rolled copper foil, necessitating grinding to ensure the coaxiality of the outer circle and the end conical surface. Existing methods for positioning the steel sleeve primarily rely on internal expansion clamps, which cannot guarantee coaxiality with the end conical surface, impacting grinding quality. For example, patent CN219901729U discloses a guide sleeve grinding fixture, including a base with a mounting disc at its top. Above the mounting disc, multiple clamping blocks are arranged in a circular array at intervals. A sleeve for limiting the clamping blocks is fixedly connected to the top of the mounting disc. A drive component for unfolding the clamping blocks is threaded through the axis of the mounting disc. Positioning is achieved through a set of unfolded internal clamping blocks. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a copper processing sleeve grinding device that ensures the coaxiality requirement between the outer circle of the sleeve and the conical surface.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] The copper processing sleeve grinding device includes a grinding spindle of an external cylindrical grinding machine, and a pair of flange structures for clamping and positioning the steel sleeve. The pair of flange structures includes a fixed flange and a movable flange. The fixed flange is fixed on the grinding spindle, and the movable flange is positioned on the grinding spindle by a locking cap. The tapered surfaces of the fixed flange and the movable flange mate with the tapered surfaces of the corresponding ports of the steel sleeve.

[0008] Further or preferred:

[0009] The taper of the outer circle of the flange is the same as the taper of the conical surface of the steel sleeve port.

[0010] The grinding spindle is equipped with a positioning flange, and the fixing flange is sleeved on the grinding spindle and welded to the positioning flange.

[0011] One end of the grinding spindle is provided with a threaded structure, and the locking cap is detachably mounted on the grinding spindle through the threaded structure.

[0012] The grinding spindle is equipped with support rubber for initial support and positioning of the steel sleeve.

[0013] The supporting rubber interference fit is mounted on the grinding spindle.

[0014] The grinding spindle is provided with a positioning annular groove, and the center of the supporting rubber is provided with an installation hole, with the inner edge of the supporting rubber located in the positioning annular groove.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] The copper processing sleeve grinding device has a reasonable structural design. The spindle and flange are precisely matched to ensure coaxiality accuracy. The taper of the outer circle of the flange is the same as the taper of the conical surface of the steel sleeve end. There are pin holes at both ends of the spindle. After the steel sleeve is fastened, the whole device is hoisted onto the cylindrical grinding machine for grinding, which ensures the coaxiality requirement between the outer circle of the sleeve and the conical surface.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0023] like Figure 1 and Figure 2 As shown, the copper processing sleeve grinding device includes a grinding spindle 1 of an external cylindrical grinding machine and a pair of flange structures for clamping and positioning the steel sleeve 5.

[0024] A pair of flange structures includes a fixed flange 2 and a movable flange 3. The fixed flange is fixed on the grinding spindle, and the movable flange is positioned on the grinding spindle by a locking cap 4. The tapered surfaces of the fixed flange and the movable flange are engaged with the tapered surfaces of the corresponding ports of the steel sleeve.

[0025] This utility model has a reasonable structural design for the copper processing sleeve grinding device. The spindle and flange are precisely matched to ensure coaxiality accuracy. The taper of the outer circle of the flange is the same as the taper of the conical surface of the steel sleeve end. There are pin holes at both ends of the spindle. After the steel sleeve is fastened, the whole device is hoisted onto the cylindrical grinding machine for grinding, which ensures the coaxiality requirement between the outer circle of the sleeve and the conical surface.

[0026] The taper of the outer circle of the flange is the same as the taper of the conical surface of the steel sleeve port; the outer circles of both the fixed flange and the movable flange are conical surfaces. Accurate positioning is achieved by matching the outer conical surface of the fixed flange with the conical surface of one port of the steel sleeve, and then matching the outer conical surface of the movable flange with the conical surface of the other port of the steel sleeve, thereby ensuring the coaxiality of the steel sleeve and the grinding spindle.

[0027] Preferred:

[0028] The grinding spindle is equipped with a positioning flange, and the fixing flange is sleeved on the grinding spindle and welded to the positioning flange, which makes the structure stable and reliable.

[0029] One end of the grinding spindle is provided with a threaded structure, and the locking cap is detachably mounted on the grinding spindle through the threaded structure; installation and disassembly are simple.

[0030] Furthermore, the grinding spindle is equipped with a support rubber 6 for initial support and positioning of the steel sleeve, and the support rubber is interference-fitted onto the grinding spindle; the installation and operation of the steel sleeve is simple.

[0031] The grinding spindle is equipped with a positioning annular groove, and the center of the support rubber is equipped with an installation hole. The inner edge of the support rubber is located in the positioning annular groove, making the support rubber stable and reliable.

[0032] The support rubber is a cylinder with a central hole, and both ends of the support rubber have chamfers on their outer edges to facilitate the positioning of the steel sleeve.

[0033] The taper of the outer diameter of the flange is the same as the taper of the conical surface of the steel sleeve end. One flange is fixed to the spindle, while the other flange is movable. After the steel sleeve is installed, the movable flange is secured with a nut. The precision fit between the spindle and the flange, along with the fit between the flange and the conical surface of the sleeve end, ensures coaxiality accuracy. The spindle has center pin holes at both ends. After securing the steel sleeve, the entire assembly is hoisted onto an external cylindrical grinding machine for grinding, ensuring the coaxiality requirements between the outer diameter of the sleeve and the conical surface.

[0034] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.
