Description

Technical Field

[0001] The invention relates to the technical field of metal grinding, and in particular to a grinding device for a high-temperature alloy resistor. Background Art

[0002] High temperature alloy resistor is a resistor that uses alloy material as the resistor body. The resistor body of alloy resistor is usually made of nickel-chromium alloy, manganese-copper alloy and other materials. These alloy materials have the characteristics of high resistivity, small temperature coefficient and good stability.

[0003] Alloy resistance strip is a strip-shaped high-temperature alloy resistor with specific resistance properties. It is usually made of nickel-chromium alloy, manganese-copper alloy, iron-chromium-aluminum alloy, etc. Different alloy components give it different properties. For example, nickel-chromium alloy has high resistivity, good oxidation resistance and corrosion resistance. Through smelting, rolling, drawing and other processes, the alloy material is processed into thin strips to meet the needs of different application scenarios.

[0004] Before forming the high-temperature alloy resistor, the unformed resistor strip needs to be polished. The purpose is to make the surface roughness of the resistor strip strictly meet the established standards, and at the same time polish the surface defects of the resistor strip, such as tiny protrusions and uneven areas, to lay the foundation for subsequent high-quality forming work.

[0005] However, currently most alloy resistors are processed by single-sided grinding. During the grinding process, due to uneven force on one side, the upper or lower side of the resistor strip is prone to produce raised burrs at the connection. These raised burrs will seriously affect the normal use of the subsequent alloy resistors. For example, in electronic circuits, burrs may cause circuit short circuits and cause the entire electronic equipment to malfunction; in high-precision instruments and meters, burrs may interfere with signal transmission and reduce measurement accuracy. If you subsequently try to use a handheld grinding tool to perform a secondary grinding on these raised burrs, it will not only be inefficient but also prone to deviations, thereby reducing the grinding effect of the alloy resistor. Summary of the invention

[0006] The present invention provides a grinding device for a high-temperature alloy resistor, which can solve the problem that in the prior art, alloy resistors are mostly ground on one side, and burrs are easily produced on the upper side or the lower side of the resistor band at the connection due to uneven force on the single side.

[0025] The following is a detailed description of the specific embodiments of the present invention, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0026] As Figures 1 to 5 shown, a grinding device for a superalloy resistor includes a grinding table 1, a feeding mechanism 2, and a grinding mechanism 3. There are two groups of feeding mechanisms 2, which are symmetrically arranged at both ends of the top of the grinding table 1. The grinding mechanism 3 is fixedly arranged on the top of the grinding table 1 and is located between the two groups of feeding mechanisms 2. The grinding mechanism 3 includes a support frame 4, a movable bracket 5, a support plate 6, and a grinding wheel 7. The support frame 4 is fixedly connected to the grinding table 1. The movable bracket 5 is slidably connected to the support frame 4. The support plate 6 is fixedly connected to the movable bracket 5. The grinding wheel 7 is rotatably connected to the movable bracket 5 and is located on one side of the support plate 6. A driving mechanism 8 for driving the grinding wheel 7 to rotate is arranged on the movable bracket 5.

[0027] The two groups of feeding mechanisms 2 symmetrically arranged at both ends of the top of the grinding table 1 are responsible for smoothly guiding the superalloy resistor tape 23 to be ground into the grinding area, ensuring the stable position of the resistor tape 23 during the transmission process, and providing a good foundation for the subsequent grinding operation.

[0028] The movable bracket 5 is slidably connected to the support frame 4. When it is necessary to grind resistor tapes 23 of different specifications or thicknesses, the relative position between the grinding wheel 7 and the resistor tape 23 can be changed by adjusting the position of the movable bracket 5 on the support frame 4 to meet different grinding requirements.

[0029] The driving mechanism 8 is started to drive the grinding wheel 7 to rotate at a high speed. Under the action of the feeding mechanism 2, the resistor tape 23 moves to the position where the grinding wheel 7 is located. The grinding wheel 7 is located on one side of the support plate 6. The support plate 6 plays a role in assisting in supporting the resistor tape 23, making the resistor tape 23 more stable during grinding. The grinding force generated by the high-speed rotation of the grinding wheel 7 acts on the surface of the resistor tape 23 to grind it. Due to the use of the symmetric feeding mechanism 2 and the support plate 6 to support the resistor tape 23, the resistor tape 23 is uniformly stressed during the grinding process, avoiding the situation of uneven single-sided stress.

[0030] By using the symmetric feeding mechanism 2 and the support plate 6 to support the resistor tape 23, the resistor tape 23 is uniformly stressed during grinding, greatly reducing the burr phenomenon caused by uneven single-sided stress, effectively improving the surface quality of the superalloy resistor, and ensuring that no faults such as short circuits and signal interference occur due to burr problems during subsequent use.

[0031] By adjusting the position of the movable support 5 to adapt to the grinding of resistor tapes 23 of different specifications, it has strong versatility and adaptability. Whether it is a thicker resistor tape 23 or a thinner resistor tape 23, this grinding device can complete high-quality grinding work through appropriate adjustment, reducing the cost for enterprises to purchase multiple devices to meet the needs of different products.

[0032] In some specific implementation manners, the grinding mechanism 3 further includes a transmission shaft 9, a transmission sleeve 10, a spring 13 and a limit block 14. The transmission shaft 9 is rotationally and cooperatively connected with the movable support 5. The transmission sleeve 10 is coaxially and fixedly connected with the grinding wheel 7. A vertical slot 11 is formed in the side of the transmission sleeve 10. A transmission block 12 that is slidably cooperated with the vertical slot 11 is fixedly arranged on the side of the transmission shaft 9. The spring 13 is arranged inside the transmission sleeve 10. One end of the spring 13 abuts against the transmission sleeve 10, and the other end of the spring 13 abuts against the transmission shaft 9. The limit block 14 is fixedly arranged at the notch of the vertical slot 11. The driving mechanism 8 includes a driving motor 15. The driving motor 15 is fixedly connected with the movable support 5, and the output end of the driving motor 15 is coaxially and fixedly connected with the transmission shaft 9.

[0033] When the grinding wheel 7 encounters unevenness or large resistance on the surface of the resistor tape 23, the spring 13 plays a buffering role inside the transmission sleeve 10. One end of the spring 13 abuts against the transmission sleeve 10, and the other end abuts against the transmission shaft 9. At this time, the spring 13 is compressed, and the transmission shaft 9 generates a displacement relative to the transmission sleeve 10, avoiding damage to the grinding wheel 7 due to instantaneous excessive impact force. The limit block 14 is fixed at the notch of the vertical slot 11 to prevent the transmission block 12 from disengaging, ensuring stable power transmission.

[0034] The buffering effect of the spring 13 effectively protects the grinding wheel 7, extends its service life, and reduces the equipment maintenance cost and replacement frequency. At the same time, it enables the grinding wheel 7 to adapt to the minute undulations and unevenness on the surface of the resistor tape 23, improving the grinding quality and consistency. The limit block 14 ensures stable and reliable power transmission, guaranteeing the continuous and stable operation of the grinding device.

[0035] In some specific implementation manners, two sets of grinding mechanisms 3 are provided, and the two sets of grinding mechanisms 3 are symmetrically and reversely arranged on the top of the grinding table 1. The upper and lower surfaces of the resistor tape 23 are ground simultaneously. The working processes of the two sets of grinding mechanisms 3 are the same as those of a single grinding mechanism 3. The resistor tape 23 is conveyed by the feeding mechanism 2, the position of the movable support 5 is adjusted, and the driving motor 15 drives the grinding wheel 7 to rotate for grinding. The grinding efficiency is significantly improved, and the time required for single-sided grinding can be shortened by nearly half. At the same time, double-sided simultaneous grinding can better ensure the overall flatness and performance consistency of the resistor tape 23, improving the product quality and meeting the production requirements of higher standards.

[0036] In some specific embodiments, the grinding mechanism 3 further includes an adjusting screw 16 and an adjusting handwheel 17. The adjusting screw 16 is vertically arranged and rotatably connected to the support frame 4, the movable bracket 5 is threadedly connected to the adjusting screw 16, and the adjusting handwheel 17 is coaxially and fixedly connected to the adjusting screw 16. Since the movable bracket 5 is threadedly engaged with the adjusting screw 16, the rotation of the adjusting screw 16 is converted into the linear movement of the movable bracket 5 along the support frame 4, thereby accurately adjusting the position of the movable bracket 5 on the support frame 4 and changing the relative position between the grinding wheel 7 and the resistance strip 23. By visually rotating the adjusting handwheel 17, the position of the movable bracket 5 can be quickly and accurately adjusted to meet the grinding requirements of different specifications of the resistance strip 23, improving the operability and production efficiency of the equipment.

[0037] In some specific embodiments, a dust collection frame 18 is fixedly arranged on the top of the grinding table 1, and both the feeding mechanism 2 and the grinding mechanism 3 are arranged inside the dust collection frame 18. A protective cover 19 is fixedly arranged on the top of the dust collection frame 18. Feed openings and discharge openings are respectively formed at both ends of the protective cover 19, and an observation window 20 is formed on the side of the protective cover 19.

[0038] The dust generated during the grinding process is collected by the dust collection frame 18. The dust collection frame 18 is fixed on the top of the grinding table 1, and both the feeding mechanism 2 and the grinding mechanism 3 are located inside the dust collection frame 18. The protective cover 19 is installed on the top of the dust collection frame 18. The feed openings and discharge openings at both ends thereof are respectively used for the entry and exit of the resistance strip 23, and the observation window 20 on the side facilitates the operator to observe the grinding process. The dust collection frame 18 effectively collects the dust generated during grinding, reduces the pollution of the working environment by dust, and protects the physical health of the operator. The protective cover 19 provides protection for the grinding device to prevent foreign objects from entering, and at the same time, the observation window 20 facilitates the operator to monitor the grinding situation in real time to ensure the smooth progress of the grinding process.

[0039] In some specific embodiments, the feeding mechanism 2 includes a rotating frame 21 and a feeding roller 22. The rotating frame 21 is vertically arranged and fixedly connected to the grinding table 1, and the feeding roller 22 is horizontally arranged and rotatably connected to the rotating frame 21. The rotating frame 21 is vertically fixed on the grinding table 1 to provide support for the feeding roller 22. The feeding roller 22 is horizontally installed on the rotating frame 21 and can rotate freely. During the conveying process of the resistance strip 23, relying on the frictional force between the resistance strip 23 and the feeding roller 22, and under the rolling action of the feeding roller 22, the resistance strip 23 is smoothly conveyed to the grinding area. The feeding mechanism 2 has a simple and stable structure and can reliably convey the resistance strip 23 smoothly into the grinding area, ensuring the stable position of the resistance strip 23 during the transmission process and laying a foundation for subsequent high-quality grinding operations.

[0040] The above discloses only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
