Description

Technical Field

[0001] This utility model relates to the field of copper foil production technology, and in particular to a centerless grinding positioning device for FRP tubes. Background Technology

[0002] FRP pipe is a composite material pipe made of fiber-reinforced plastic, mainly composed of resin and fiber. The resin is usually thermosetting polyester, epoxy resin, or phenolic resin, while the fiber is mainly glass fiber, especially "E-glass". This material has advantages such as high strength, corrosion resistance, and light weight, and is widely used in chemical, petroleum, agricultural, and environmental protection industries.

[0003] In copper foil production, FRP tubes are used as core materials for winding copper foil during the production process. The high strength and wear resistance of FRP tubes ensure that they are not easily damaged under high-speed operation and high tension, thus guaranteeing the continuity and stability of production.

[0004] In copper foil production, centerless grinders are typically used to grind FRP tubes. Grinding improves the flatness and smoothness of the FRP tube surface, making it better suited for copper foil winding processes, reducing defect rates, and ensuring product quality stability. Existing centerless grinders (such as the one disclosed in application number 200510109637.5) use a guide wheel that rotates at a slower speed to create a speed difference with the high-speed rotating grinding wheel. This friction drives the FRP tube to rotate and provides sufficient axial thrust to achieve surface grinding and polishing. However, assembly errors or unsuitable guide wheel rotation speeds can cause the FRP tube to bounce on the pallet, affecting processing accuracy. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an FRP tube centerless grinding positioning device to solve the technical problem in the prior art that the FRP tube jumps on the pallet due to assembly errors of the equipment or unsuitable rotation speed of the guide wheel, which affects the processing accuracy.

[0006] To achieve the above technical objectives, the present invention provides an FRP tube centerless grinding positioning device, comprising: Two positioning mechanisms are arranged opposite each other and spaced apart on the same horizontal plane, and are located at both ends of the pipe fitting, including an insert and an abutment that are connected to each other; An adjustment mechanism, which is connected to both of the positioning mechanisms, is used to drive the two positioning mechanisms to move closer to each other or further away from each other, so that the two inserts are slidably inserted into the two ends of the tube in a one-to-one correspondence, and the two abutting members abut against the two end faces of the tube in a one-to-one correspondence. A translation mechanism, connected to the adjustment mechanism, is used to drive the adjustment mechanism to move horizontally reciprocally along the axial direction of the guide wheel or grinding wheel, so that the pipe fitting moves horizontally reciprocally along the axial direction of the guide wheel or grinding wheel.

[0007] Furthermore, the insert includes multiple inserts arranged in a ring array to enclose an insertion interval. The abutment is slidably connected to each insert. The positioning mechanism also includes a driving component connected to the abutment and each insert, used to drive each insert to retract or separate from each other to adjust the diameter of the insertion interval.

[0008] Furthermore, the abutment member has a columnar structure and multiple guide grooves are provided on the abutment member. Each guide groove is distributed in a ring array structure and extends radially along the abutment member. Each guide groove is slidably connected to each insert member in a one-to-one correspondence.

[0009] Furthermore, the driving assembly includes a rotating disk and a first rotating driving member. The rotating disk is rotatably connected to the abutment member and can rotate around its own axis. The rotating disk has multiple arc-shaped grooves, which are distributed in a circular array structure and extend along the rotation direction of the rotating disk. Each arc-shaped groove is slidably connected to each of the insert members. The fixed end of the first rotating driving member is fixedly connected to the abutment member, and the output end of the first rotating driving member is coaxially fixedly connected to the rotating disk for driving the rotating disk to rotate.

[0010] Furthermore, the insert includes a guide block, an insertion rod, and a sliding shaft. The guide block is slidably connected to the guide groove. One end of the insertion rod is fixedly connected to one side of the guide block, and the other end of the insertion rod is used to slide into one end of the tube. One end of the sliding shaft is fixedly connected to the other side of the guide block, and the other end of the sliding shaft is slidably connected to the arc-shaped groove.

[0011] Furthermore, a keyway extending along the length direction is provided on the side wall of the guide groove, and the insert also includes a key block, which is fixedly connected to the guide block and slidably connected to the keyway.

[0012] Furthermore, the adjustment mechanism includes a mounting frame, at least one first guide rod, a drive rod, two connecting rods, and a second rotation drive component. Each of the first guide rods and the drive rod is horizontally arranged and extends axially along the guide wheel or grinding wheel. Both ends of each first guide rod are fixedly connected to the mounting frame. Both ends of the drive rod are rotatably connected to the mounting frame. The drive rod has two sections of threads with opposite directions and equal lengths. Each of the two connecting rods has at least one through hole and one threaded hole at its upper end, and is slidably fitted onto each of the guide rods through the through holes and onto the drive rods through the threaded holes. The two threaded holes and the two threads are screwed together. The lower ends of the two connecting rods are fixedly connected to two abutment members. The fixed end of the second rotation drive component is fixedly connected to the mounting frame, and the output end of the second rotation drive component is coaxially fixedly connected to one end of the drive rod for driving the drive rod to rotate.

[0013] Furthermore, the translation mechanism includes a support beam and a moving drive component. The support beam is horizontally arranged and extends along the axial direction of the guide wheel or grinding wheel. The moving drive component is slidably connected to the support beam and can reciprocate along the length direction of the support beam. The moving drive component is also connected to the adjustment mechanism.

[0014] Furthermore, the FRP pipe centerless grinding positioning device also includes a lifting mechanism, which is connected to the adjusting mechanism and is used to drive the adjusting mechanism to move up and down so that the pipe fitting abuts or separates from the guide wheel and the grinding wheel. The translation mechanism is connected to the lifting mechanism and is used to drive the lifting mechanism to move horizontally back and forth along the axial direction of the guide wheel or the grinding wheel.

[0015] Furthermore, the lifting mechanism includes a mounting base, at least one second guide rod, and a telescopic drive component.

[0016] Compared with the prior art, the beneficial effects of this utility model include: During use, the pipe is placed between the guide wheel and grinding wheel of the centerless grinder, and the pipe abuts against the guide wheel and grinding wheel. By controlling the adjustment mechanism, the adjustment mechanism drives the two positioning mechanisms to move closer to each other, allowing the two inserts to slide into the two ends of the pipe in a one-to-one correspondence. It also allows the two abutting parts to abut against the two end faces of the pipe in a one-to-one correspondence. Thus, the radial positioning of the pipe can be achieved through the two inserts, and the axial positioning of the pipe can be achieved through the cooperation of the two abutting parts. Furthermore, by controlling the translation mechanism, the translation mechanism drives the adjustment mechanism to move horizontally back and forth along the axial direction of the guide wheel or grinding wheel, allowing the pipe to move horizontally back and forth along the axial direction of the guide wheel or grinding wheel. This ensures that the grinding wheel grinds and polishes the pipe at various axial positions. This FRP pipe centerless grinder positioning device can position the pipe radially and axially, preventing the pipe from jumping on the support plate and ensuring processing accuracy.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0019] This utility model provides a centerless grinding positioning device for FRP tubes, the structure of which is as follows: Figure 1 - Figure 2As shown, the device includes two positioning mechanisms 100, an adjusting mechanism 200, and a translation mechanism 300. The two positioning mechanisms 100 are arranged opposite each other and spaced apart on the same horizontal plane, and are located at both ends of the pipe fitting 1. Each positioning mechanism includes an insert 110 and an abutment 120 connected to each other. The adjusting mechanism 200 is connected to both positioning mechanisms 100 and is used to drive the two positioning mechanisms 100 to move closer to each other or further away from each other, so that the two inserts 110 are slidably inserted into both ends of the pipe fitting 1 in a one-to-one correspondence, and the two abutments 120 abut against the two end faces of the pipe fitting 1 in a one-to-one correspondence. The translation mechanism 300 is connected to the adjusting mechanism 200 and is used to drive the adjusting mechanism 200 to move horizontally back and forth along the axial direction of the guide wheel 2 or the grinding wheel 3, so that the pipe fitting 1 moves horizontally back and forth along the axial direction of the guide wheel 2 or the grinding wheel 3.

[0020] In use, the tube 1 is placed between the guide wheel 2 and the grinding wheel 3 of the centerless grinder, and the tube 1 abuts against the guide wheel 2 and the grinding wheel 3. By operating the adjustment mechanism 200, the adjustment mechanism 200 drives the two positioning mechanisms 100 to move closer to each other, so that the two inserts 110 can be slidably inserted into the two ends of the tube 1 one-to-one, and the two abutting members 120 can abut against the two end faces of the tube 1 one-to-one. Thus, the tube 1 can be radially positioned by the two inserts 110, and the two abutting members 120 can abut against the two end faces of the tube 1. The mutual cooperation of the connectors 120 can position the pipe 1 axially. Then, by operating the translation mechanism 300, the adjustment mechanism 200 is driven to move horizontally back and forth along the axis of the guide wheel 2 or the grinding wheel 3. This allows the pipe 1 to move horizontally back and forth along the axis of the guide wheel 2 or the grinding wheel 3, thereby ensuring that the grinding wheel 3 grinds and polishes the pipe 1 at various positions along the axis. This FRP pipe centerless grinding positioning device can position the pipe 1 radially and axially, preventing the pipe 1 from jumping on the support plate and ensuring processing accuracy.

[0021] As a preferred embodiment, please refer to Figure 2 and Figure 3The insert 110 includes multiple inserts arranged in a ring array to form an insertion interval. The abutment 120 is slidably connected to each insert 110. The positioning mechanism 100 also includes a drive assembly 130, which connects the abutment 120 and each insert 110. The drive assembly 130 drives each insert 110 to retract or separate, thereby adjusting the diameter of the insertion interval. Based on the inner diameter of the pre-polished pipe 1, the diameter of the insertion interval is pre-adjusted to match the inner diameter of the pipe 1. By manipulating the drive assembly 130, the inserts 110 can retract or separate, thus adjusting the diameter of the insertion interval. This FRP pipe centerless grinding positioning device can position pipes 1 within a certain diameter range and has strong applicability.

[0022] As a preferred embodiment, please refer to Figure 2 and Figure 3 The abutment member 120 has a columnar structure and multiple guide grooves 121 are provided on the abutment member 120. The guide grooves 121 are distributed in a ring array structure and extend radially along the abutment member 120. Each guide groove 121 is slidably connected to each insert member 110 in a one-to-one correspondence. Thus, the insert members 110 can be guided and limited by the guide grooves 121, so that the insert members 110 can move radially along the abutment member 120, realizing the mutual closing or separation of the insert members 110.

[0023] As a preferred embodiment, please refer to Figure 2 and Figure 3The driving assembly 130 includes a rotating disk 131 and a first rotating driving member 132. The rotating disk 131 is rotatably connected to the abutment member 120 and can rotate around its own axis. The rotating disk 131 has multiple arc-shaped grooves 1311 arranged in a circular array and extending along the rotation direction of the rotating disk 131. Each arc-shaped groove 1311 is slidably connected to each of the inserts 110. The fixed end of the first rotating driving member 132 is fixedly connected to the abutment member 120. The output end is coaxially and fixedly connected to the rotating disk 131 to drive the rotating disk 131 to rotate. When the first rotation drive 132 is activated, the output end of the first rotation drive 132 rotates, which can drive the rotating disk 131 to rotate. Since each of the inserts 110 is restricted by the corresponding guide groove 121 and the arc groove 1311, when the rotating disk 131 rotates in the forward or reverse direction, the inserts 110 can be retracted or separated, thereby adjusting the diameter of the insertion interval and adapting to pipe fittings 1 of different sizes.

[0024] As a preferred embodiment, please refer to Figure 2 and Figure 3 The insert 110 includes a guide block 111, an insertion rod 112, and a sliding shaft 113. The guide block 111 is slidably connected to the guide groove 121. One end of the insertion rod 112 is fixedly connected to one side of the guide block 111, and the other end of the insertion rod 112 is used to slide into one end of the tube 1. One end of the sliding shaft 113 is fixedly connected to the other side of the guide block 111, and the other end of the sliding shaft 113 is slidably connected to the arc-shaped groove 1311. The structure of the insert 110 can ensure the stability of its movement and the high-precision axial positioning of the tube 1.

[0025] As a preferred embodiment, please refer to Figure 2 and Figure 3 The guide groove 121 has a keyway 1211 extending along its length on its side wall. The insert 110 also includes a key block 114, which is fixedly connected to the guide block 111 and slidably connected to the keyway 1211. The guide block 111 can be limited by the cooperation between the keyway 1211 and the key block 114, so that the guide block 111 is slidably restricted within the guide groove 121.

[0026] As a preferred embodiment, please refer to Figure 2 and Figure 3The abutment member 120 has a columnar cavity 122, which is connected to each of the guide grooves 121. The rotating disk 131 is arranged in the cavity 122, and the rotating disk 131 can be contained and limited by the cavity 122.

[0027] As a preferred embodiment, please refer to Figure 2 and Figure 3 The abutment 120 includes a seat body 123 and a seat cover 124. The seat body 123 has a cavity 122, and the seat cover 124 has a plurality of guide grooves 121 to facilitate the disassembly and assembly of the rotating disk 131.

[0028] As a preferred embodiment, please refer to Figure 1 and Figure 2 The adjustment mechanism 200 includes a mounting frame 210, at least one first guide rod 220, a drive rod 230, two connecting rods 240, and a second rotation drive component 250.

Both ends of each first guide rod 220 are fixedly connected to the mounting frame 210, and both ends of the drive rod 230 are rotatably connected to the mounting frame 210. The drive rod 230 has two threads with opposite directions and equal lengths. Each of the two connecting rods 240 has at least one through hole and one threaded hole at its upper end, and is slidably fitted onto each of the guide rods through the through holes and onto the drive rod 230 through the threaded holes. The two screw holes are screwed into the two threads one-to-one. The lower ends of the two connecting rods 240 are fixedly connected to the two abutment members 120 one-to-one. The fixed end of the second rotation drive member 250 is fixedly connected to the mounting bracket 210. The output end of the second rotation drive member 250 is coaxially fixedly connected to one end of the drive rod 230 for driving the drive rod 230 to rotate. When the second rotation drive member 250 is activated, the output end of the second rotation drive member 250 rotates, which can drive the drive rod 230 to rotate. Since the two connecting rods 240 are restricted by the first guide rod 220, when the drive rod 230 rotates in the forward or reverse direction, the two connecting rods 240 can move closer to each other or move further away from each other.

[0029] As a preferred embodiment, please refer to Figure 1The translation mechanism 300 includes a support beam 310 and a moving drive component 320.

The moving drive component 320 is slidably connected to the support beam 310 and can reciprocate along the length direction of the support beam 310. The moving drive component 320 is also connected to the adjustment mechanism 200. When the moving drive component 320 is activated, it can move along the length direction of the support beam 310.

[0030] As a preferred embodiment, please refer to Figure 1 The moving drive component 320 is a linear motor.

[0031] As a preferred embodiment, please refer to Figure 1 The FRP pipe centerless grinding positioning device further includes a lifting mechanism 400, which is connected to the adjusting mechanism 200 and is used to drive the adjusting mechanism 200 to move up and down so that the pipe 1 abuts or separates from the guide wheel 2 and the grinding wheel 3. The translation mechanism 300 is connected to the lifting mechanism 400 and is used to drive the lifting mechanism 400 to move horizontally reciprocally along the axial direction of the guide wheel 2 or the grinding wheel 3. The mutual cooperation of the adjusting mechanism 200, the translation mechanism 300 and the lifting mechanism 400 can realize the self-loading and self-unloading process of the pipe 1 without manual operation, and can realize the automated grinding and polishing of the pipe 1.

[0032] As a preferred embodiment, please refer to Figure 1 The lifting mechanism 400 includes a mounting base 410, at least one second guide rod 420, and a telescopic drive component 430.

The translation mechanism 300 is connected to the mounting base 410. When the telescopic drive component 430 is activated, the output end of the telescopic drive component 430 extends or retracts, which can drive the adjusting mechanism 200 to move up and down, thereby allowing the pipe 1 to be placed between the guide wheel 2 and the grinding wheel 3 or to be moved out from between the guide wheel 2 and the grinding wheel 3.

[0033] As a preferred embodiment, please refer to Figure 1 The lower ends of each of the second guide rods 420 are fixedly connected to the mounting bracket 210, and the output end of the telescopic drive component 430 is fixedly connected to the mounting bracket 210.

[0035] To better understand this utility model, the following is combined with... Figure 1 - Figure 3 The working principle of the technical solution of this utility model will be described in detail below: In use, the diameter of the insertion section is pre-adjusted according to the inner diameter of the pre-ground and polished pipe fitting 1, so that the diameter of the insertion section matches the inner diameter of the pipe fitting 1. The first rotation drive 132 is activated, and the output end of the first rotation drive 132 rotates, which can drive the rotating disk 131 to rotate. Since each insertion piece 110 is restricted by the corresponding guide groove 121 and the arc groove 1311, when the rotating disk 131 rotates forward or backward, the insertion pieces 110 can be retracted or separated, thereby adjusting the diameter of the insertion section. Adaptable to pipe fittings 1 of different sizes, the second rotation drive 250 is activated, and its output end rotates, driving the drive rod 230 to rotate. Because the two connecting rods 240 are restricted by the first guide rod 220, during the forward rotation of the drive rod 230, the two connecting rods 240 can move closer to each other, allowing the two inserts 110 to slide into both ends of the pipe fitting 1 in a one-to-one correspondence. Furthermore, the two abutting members 120 can abut against the two end faces of the pipe fitting 1 in a one-to-one correspondence, thereby enabling radial positioning of the pipe fitting 1 through the two inserts 110. The two abutment members 120 cooperate to position the pipe 1 axially. Then, the telescopic drive 430 is activated, and its output end shortens, driving the adjusting mechanism 200 to move upward. The moving drive 320 is activated, moving along the length of the support beam 310 so that the pipe 1 is directly above the guide wheel 2 and the grinding wheel 3. Next, the telescopic drive 430 is activated, and its output end extends, driving the adjusting mechanism 200 to move downward, allowing the pipe 1 to be placed between the guide wheel 2 and the grinding wheel 3, and the pipe... When component 1 abuts against guide wheel 2 and grinding wheel 3, the coordinated action of adjustment mechanism 200, translation mechanism 300 and lifting mechanism 400 enables the self-loading and self-unloading process of component 1. When the moving drive component 320 is restarted, the moving drive component 320 moves along the length direction of the support beam 310, which allows component 1 to move horizontally back and forth along the axial direction of guide wheel 2 or grinding wheel 3, thereby ensuring that grinding wheel 3 grinds and polishes various positions of component 1 in the axial direction. This FRP pipe centerless grinding positioning device can position component 1 radially and axially, preventing component 1 from jumping on the pallet and ensuring processing accuracy.

[0036] The FRP tube centerless grinding positioning device provided by this utility model has the following beneficial effects: (1) This FRP pipe centerless grinding positioning device can realize the positioning of pipe fittings 1 within a certain diameter range, and has strong applicability; (2) The coordinated action of the adjustment mechanism 200, the translation mechanism 300 and the lifting mechanism 400 can realize the self-loading and self-unloading process of the pipe fitting 1 without manual operation, and can realize the automated grinding and polishing of the pipe fitting 1. (3) This FRP pipe centerless grinding positioning device can position the pipe 1 radially and axially, which can prevent the pipe 1 from jumping on the pallet and ensure processing accuracy.
