Description

Technical Field

[0001] The utility model belongs to the technical field of diamond wire production, and particularly relates to a length measuring device for taking up diamond wire. Background Art

[0002] The length measuring wheel, also known as a length measuring instrument, is mainly used for precise length measurement on continuous coil processing equipment. There are various forms of length measuring wheels on the market, and the measurement principles are also different.

[0003] During the process of taking up diamond wire in production, the length of the produced diamond wire is calculated by the cooperation of the length measuring wheel and the encoder. At present, the length measuring wheel is sleeved on the length measuring wheel shaft through a bearing, and a rubber ring is sleeved on the outer periphery of the length measuring wheel for winding the diamond wire. Since the part of the rubber ring in contact with the diamond wire is scrapped after a certain period of use, if it is used again, wire breakage is likely to occur. If the rubber ring is directly replaced, the cost is high and it causes waste. Therefore, the length measuring wheel usually needs to be axially moved so that the contact position between the wound diamond wire and the wire groove of the rubber ring changes and then work is carried out. However, it is not easy to control the moving distance when the length measuring wheel is axially moved. At present, an interference fit is mostly used for installation between the length measuring wheel and the bearing and between the bearing and the length measuring wheel shaft, resulting in difficult disassembly and assembly of the length measuring wheel. When disassembling, the bearing is easily damaged, increasing the production cost. Summary of the Invention

[0004] In order to solve the problems that when the existing length measuring wheel is installed, it is directly installed through a bearing, and due to the interference fit installation between the length measuring wheel and the bearing and between the bearing and the length measuring wheel shaft, the disassembly and assembly of the length measuring wheel are difficult, the bearing is easily damaged during disassembly, increasing the production cost and the disassembly and assembly are troublesome, the utility model provides a length measuring device for taking up diamond wire. By arranging an installation ring outside the bearing and enabling the length measuring wheel and the installation ring to be fixedly connected through screws, the installation of the length measuring wheel can be realized. When disassembling, only the screws need to be loosened to disassemble the length measuring wheel, and there is no need to disassemble the bearing. The structure is simple and the use is convenient.

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0006] A length measuring device for taking up diamond wire is arranged on a length measuring wheel shaft and includes a bearing, an installation ring, a length measuring wheel and screws. One end of the length measuring wheel shaft is sleeved with a bearing, and an installation ring is fixedly sleeved on the outer periphery of one end of the bearing. Screw holes are axially arranged on the installation ring, and the length measuring wheel is fixedly sleeved on the bearing; a plurality of arc holes and round holes are circumferentially arranged on the length measuring wheel, one end of adjacent arc holes is communicated with the round holes, the rod body of the screw passes through the arc holes and is in threaded connection with the corresponding screw holes, and the diameter of the round holes is larger than the diameter of the head of the screw. When disassembling the length measuring wheel, loosen the screws and rotate the length measuring wheel to align the round holes with the screws, then the length measuring wheel can be removed.

[0007] Preferably, a rubber sleeve is provided on the fixed sleeve on the outer circumference of the meter wheel, and two waist-shaped measuring through holes are opened on the meter wheel with the meter wheel axis as the symmetry center. The measuring through holes are long arc holes, and the arc center is located on the axis of the meter wheel axis. The symmetrical arrangement of the measuring through holes ensures uniform mass distribution of the meter wheel.

[0008] Preferably, the end of the bearing away from the mounting ring is configured to be conical, and the conical angle a is 5°, so as to facilitate alignment and installation of the meter wheel and the bearing.

[0009] Preferably, a mounting groove is provided on the inner side of the rubber sleeve and a wire passing groove is provided on the outer side. The cross-section of the rubber sleeve is H-shaped. The two opposite side walls of the wire passing groove are inclined, and the angle b between the two inclined side walls is 14° to prevent the diamond wire from falling off the wheel.

[0010] Preferably, the spacing between the inner sides of the two side walls of the wire groove is 4 mm.

[0011] Preferably, the thickness of the meter wheel is set to 3 mm.

[0012] Through the above technical solution, the beneficial effects of the utility model are:

[0013] 1. The utility model realizes a fixed connection between the meter wheel and the bearing through a mounting ring arranged on the outer side of the bearing and screws. When the meter wheel needs to be disassembled, it is only necessary to rotate the screws without disassembling the bearing, thereby extending the service life of the bearing.

[0014] 2. The utility model provides interconnected arc holes and round holes, so that when disassembling and assembling the meter wheel, there is no need to unscrew the screws. The meter wheel can be disassembled and assembled by simply rotating the meter wheel. When the head of the screw is opposite to the round hole, the screw head is staggered from the round hole and opposite to the arc hole. Then, the screw is tightened to achieve installation and fixation of the meter wheel.

[0015] 3. The utility model reduces the distance between the two side walls of the wire groove (from the original 14mm to 4mm in the utility model), and then determines the bearing installation position during installation. The wire groove corresponding to the outer rubber ring of the meter wheel that is installed is close to the end of the installation ring that contacts the diamond wire. After a certain period of use (usually a wire-retrieving length of about 4500km), the meter wheel is directly removed and its end face is installed in reverse, so that the diamond wire can be wound again and the original contact position between the diamond wire and the inner wall of the wire groove is avoided, avoiding the problem that it is difficult to grasp the adjustment distance and the adjustment is troublesome when adjusting the position of the meter wheel along the axial direction. At the same time, the thickness of the meter wheel is correspondingly reduced, effectively reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0024] like Figures 1 to 6 As shown, this embodiment provides a metering device for diamond wire take-up, which is arranged on a meter wheel shaft 1. The meter wheel shaft 1 can be connected to an encoder to monitor the take-up length, including a bearing 2, a mounting ring 3, a meter wheel 4 and a screw 5. One end of the meter wheel shaft 1 is sleeved with a bearing 2, and the outer periphery of one end of the bearing 2 is fixedly sleeved with a mounting ring 3, that is, the axial length of the bearing 2 is greater than the mounting ring 3, and the mounting ring 3 is axially arranged with screw holes 6. The meter wheel 4 is fixedly sleeved on the bearing 2, and the thickness of the meter wheel 4 is set to 3mm.

[0025] like Figure 1 As shown, the meter wheel 4 is provided with a plurality of arc holes 7 and circular holes 8 in the circumferential direction, one end of the adjacent arc hole 7 is connected with the circular hole 8, the shaft of the screw 5 passes through the arc hole 7 and is threadedly connected with the corresponding screw hole 6, the diameter of the circular hole 8 is larger than the head diameter of the screw 5, and the distance between the inner side and the outer side of the arc hole 7 is smaller than the head diameter of the screw 5. When installing the meter wheel 4, the plurality of circular holes 8 are respectively sleeved on the outer side of the corresponding screw 5, and the meter wheel 4 is rotated. When the plurality of screws 5 are staggered with the corresponding circular holes 8, the installation and fixation of the meter wheel 4 can be completed by tightening the screws 5. When disassembling the meter wheel 4, the screws 5 are loosened, and the meter wheel 4 is rotated so that the plurality of circular holes 8 correspond to the plurality of screws 5 respectively, and then the meter wheel 4 can be removed.

[0026] A rubber sleeve 9 is fixedly sleeved on the outer periphery of the meter counting wheel 4. The rubber sleeve 9 can be made of POM material. At this time, iron can be correspondingly selected as the material of the meter counting wheel 4. Compared with the currently commonly used rubber or polyurethane rubber sleeve combined with an aluminum alloy meter counting wheel, the product cost is effectively reduced. Two kidney-shaped measuring through holes 10 are formed in the meter counting wheel 4 with the meter counting wheel shaft 1 as the symmetry center. The measuring through holes 10 are long arc holes, and the center of the arc is located on the axis of the meter counting wheel shaft 1. The symmetrically arranged measuring through holes 10 meet the measurement requirements of the meter counter while ensuring the mass uniformity of the meter counting wheel 4 during rotation and ensuring the balance performance of the meter counting wheel 4.

[0027] The end of the bearing 2 away from the mounting ring 3 is tapered, and its tapered angle a is 5°. When installing the meter counting wheel 4, it is convenient for the meter counting wheel 4 and the bearing 2 to be correspondingly sleeved, improving the installation convenience.

[0028] An installation groove 11 is arranged on the inner side of the rubber sleeve 9, and a wire groove 12 is arranged on the outer side. The cross section of the rubber sleeve 9 is in an H shape. The two opposite side walls of the wire groove 12 are both inclined, and the included angle b between the two inclined side walls is 14°. The inner distance between the two side walls of the wire groove 12 is 4 mm. During use, only need to disassemble the meter counting wheel 4 and install it in the reverse direction. After using it twice, the rubber sleeve 9 can be replaced, avoiding the problem that it is not easy to grasp the moving distance and the moving is troublesome when the meter counting wheel 4 moves axially.

[0029] During use, first install the bearing 2 at the end of the meter counting wheel shaft 1, and then install the meter counting wheel 4 casually. At this time, the diamond wire wound around the rubber sleeve 9 is located at one end close to the mounting ring 3 in the wire groove 12. When the wire collection length reaches about 4500 km, disassemble the meter counting wheel 4 and install it with its end face in the reverse direction. Then the original position in the wire groove 12 that contacted the diamond wire is located at one end away from the mounting ring 3, and the rubber sleeve 9 that was originally at one end away from the mounting ring 3 is now at one end close to the mounting ring 3 and contacts the newly wound diamond wire, effectively avoiding problems such as wire breakage caused by the contact between the used rubber sleeve position and the diamond wire again. After using the same rubber sleeve 9 twice, replace the rubber sleeve 9 and then the wire collection and meter counting work can be carried out again.

[0030] The above embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent should be included in the scope of the patent application of the present invention.
