Adjustable brush disc assembly of cleaning machine for copper crucible of vacuum self-consuming furnace

Abstract

The utility model discloses an adjustable brush disc assembly of a cleaning machine for a copper crucible of a vacuum self-consuming furnace, which belongs to the technical field of industrial cleaning and realizes synchronous movement of a pressing block by arranging a driving mechanism and a tensioning mechanism on a circular brush disc. Specifically, the driving mechanism drives the lead screw nuts at the two ends to linearly move in the same direction or opposite directions through rotation of the two-way lead screw. The movement is transmitted to the corresponding pressing blocks through the lead screw nuts, so that the pressing blocks conduct linear movement in the same direction or opposite directions. The movement of the pressing blocks further drives the curved connecting rods, so that the connecting plates rotate, and then the other two curved connecting rods and the corresponding pressing blocks are driven to move synchronously. In this way, the two-way lead screw can drive the four pressing blocks to be synchronously close to or away from the center of the round brush disc, and tensioning motion is achieved; due to the fact that the steel wires used for cleaning are arranged on the pressing blocks, the diameter of the brush disc assembly can be adjusted according to needs, the cleaning efficiency is improved, and the cost and the workload are reduced.

Description

Technical Field

[0001] The utility model belongs to industrial cleaning technology, and in particular relates to an adjustable brush plate component of a cleaning machine for a vacuum consumable furnace copper crucible. Background Art

[0002] In the field of metal smelting, copper crucibles are mainly used for high-temperature processes such as melting and refining of metals. After each smelting, copper crucibles may accumulate stains and residues, which may interfere with subsequent experiments and process flows. Therefore, after each smelting, the copper crucible needs to be cleaned to ensure that it does not have a negative impact on subsequent use.

[0003] Since industrial copper crucibles are large in size and manual cleaning takes a long time, mechanical tools are needed for cleaning. The patent document with announcement number CN217289687U discloses a device suitable for automatic cleaning of crucibles, which includes a main frame, a cleaning spindle, a motor, a brush disc and an electrical control system; wherein the electrical control system controls the rotation of the cleaning spindle to drive the brush disc up and down to clean the crucible, and after the cleaning is completed, the crucible is blown and dried to complete the cleaning of the crucible. The size of the brush disc can be adjusted at any time according to the size of the crucible to be cleaned, reducing the intensity of manual labor. However, the brush disc design has certain limitations, because their diameter is fixed, which means that when facing copper crucibles of different specifications, brush discs of different specifications need to be replaced to adapt. Not only does it increase the factory's inventory cost, because it is necessary to reserve brush discs of various specifications, but it also increases the workload of cleaning personnel and reduces the efficiency of cleaning work.

[0004] In summary, existing fixed-specification brushing tools have the problems of high cost, heavy workload and low efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an adjustable brush plate assembly for a vacuum consumable furnace copper crucible cleaning machine in view of the above-mentioned deficiencies in the prior art, which has a novel and reasonable design, a simple structure, strong practicability and is easy to promote and use.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] An adjustable brush plate assembly of a cleaning machine for a copper crucible of a vacuum consumable furnace comprises a circular brush plate, a mounting sleeve, a driving mechanism and a pressing block for fixing a steel wire;

[0008] The mounting sleeve is fixed at the center of the front face of the circular brush disc, and the four pressing blocks are symmetrically arranged on the front face of the circular brush disc. The pressing blocks are connected to the circular brush disc through a sliding structure to enable the pressing blocks to slide radially along the circular brush disc.

[0009] The driving mechanism is fixed on the back of the circular brush disc, and the driving mechanism drives the pressing block to move synchronously through the tensioning mechanism;

[0010] The driving mechanism includes a bidirectional lead screw and a lead screw nut. Both ends of the bidirectional lead screw are arranged on the circular brush disc through a lead screw mounting seat. Both ends of the bidirectional lead screw are respectively processed with left-handed and right-handed threads, and each thread is connected with a lead screw nut. The lead screw nut passes through the circular brush disc and is fixedly connected to a clamping block at a corresponding position.

[0011] The tensioning mechanism includes a connecting plate with a square structure and four curved connecting rods. The connecting plate can be rotatably connected to the mounting sleeve. The four corners of the connecting plate are rotatably connected to one end of the curved connecting rod, and the other end of the curved connecting rod is connected to the clamping block.

[0012] Furthermore, the sliding structure includes a guide rail with a female dovetail groove structure and a slider with a male dovetail groove structure, the guide rail is fixedly connected to the circular brush disc, and the slider is fixedly connected to the pressing block.

[0013] Furthermore, a limiting protrusion is provided on the connecting plate, and a limiting ring is provided on the mounting sleeve to limit the rotation range of the connecting plate relative to the mounting sleeve.

[0014] Furthermore, the clamping block includes a connecting plate, a clamping groove, a cover plate and a clamping bolt; the clamping groove is fixed on the connecting plate, and the cover plate is connected with the clamping groove to form a steel wire fixing groove, and the steel wire fixing groove is used to fix the steel wire;

[0015] A pressing plate is provided below the cover plate, and a bolt hole is provided on the cover plate. The clamping bolt passes through the bolt hole to press the pressing plate, so as to adjust the height of the steel wire fixing groove;

[0016] The width of the pressing plate is equal to the width of the pressing groove.

[0017] Furthermore, two connecting plates are provided, each of which has a first connecting hole at its four corners and correspondingly includes four cylindrical pins, which pass through the connecting hole of one connecting plate, the pin hole and the connecting hole of another connecting plate to achieve a rotatable connection between the connecting plate and the curved connecting rod.

[0018] Furthermore, a plurality of weight-reducing holes are provided on the circular brush disc.

[0019] Furthermore, a support column is arranged on the back of the circular brush disc.

[0020] Furthermore, two handles are detachably connected to the front of the circular brush plate.

[0021] Compared with the prior art, the utility model has the following advantages:

[0022] The utility model patent designs an adjustable brush plate assembly for a cleaning machine for copper crucibles in a vacuum consumable furnace. By setting a driving mechanism and a tensioning mechanism on the circular brush plate, the synchronous movement of the clamping block is realized. Specifically, the driving mechanism drives the screw nuts at both ends to perform linear motion in opposite or opposite directions through the rotation of the bidirectional screw. This motion is transmitted to the corresponding clamping block through the screw nut, causing it to perform linear motion in opposite or opposite directions. The movement of the clamping block further drives the curved connecting rod to rotate the connecting plate, thereby driving the other two curved connecting rods and the corresponding clamping block to perform synchronous motion. In this way, the bidirectional screw can drive the four clamping blocks to synchronously approach or move away from the center of the circular brush plate to achieve tensioning motion. Since the clamping block is equipped with a steel wire for cleaning, this design allows the diameter of the brush plate assembly to be adjusted as needed to adapt to the cleaning of steel crucibles of different models. This adjustable diameter design solves the problems of high cost, heavy workload and low cleaning efficiency of traditional fixed-specification brush plate tools, and improves the flexibility and efficiency of cleaning work.

[0037] Embodiment of the adjustable brush plate assembly of the vacuum consumable furnace copper crucible cleaning machine:

[0038] like Figure 1-Figure 4 As shown, the adjustable brush disc assembly of the vacuum consumable furnace copper crucible cleaning machine realizes the synchronous movement of the clamping block 4 by arranging a driving mechanism 3 and a tensioning mechanism 5 on the circular brush disc 1. Specifically, the brush disc assembly includes a circular brush disc 1, a mounting sleeve 2, a driving mechanism 3 and a clamping block 4 for fixing a steel wire. The mounting sleeve 2 is used to connect with an existing drive shaft, and the circular brush disc 1 is driven by the drive shaft to rotate and telescopically move, so as to realize the function of cleaning the copper crucible.

[0039] In order to ensure the uniformity and efficiency of cleaning, Figure 2 As shown, the mounting sleeve 2 is fixed at the center of the front face of the circular brush disc 1, and the four pressing blocks 4 are symmetrically arranged on the front face of the circular brush disc 1. The pressing blocks 4 are connected to the circular brush disc 1 through a sliding structure 6 to enable the pressing blocks 4 to slide radially along the circular brush disc 1. The movement of the pressing blocks 4 is limited by the sliding structure 6.

[0040] The sliding structure 6 includes a guide rail 61 with a female dovetail groove structure and a slider 62 with a male dovetail groove structure. The guide rail 61 is fixedly connected to the circular brush disc 1, and the slider 62 is fixedly connected to the clamping block 4. Due to its shape characteristics, the dovetail groove structure can provide precise positioning and guidance, ensuring that the clamping block 4 slides stably along a predetermined path and reducing offset and error. Since the guide rail 61 is fixedly connected to the brush disc and the slider 62 is fixedly connected to the clamping block 4, the synchronous movement of the clamping block 4 and the brush disc can be achieved, ensuring that the clamping block 4 moves evenly along the radial direction of the brush disc.

[0041] like Figure 3As shown, the driving mechanism 3 is fixed on the back of the circular brush disc 1, and the driving mechanism 3 drives the clamping block 4 to move synchronously through the tensioning mechanism 5. Specifically, the driving mechanism 3 includes a bidirectional lead screw 31 and a lead screw nut 32. The two ends of the bidirectional lead screw 31 are arranged on the circular brush disc 1 through a lead screw mounting seat 33. The two ends of the bidirectional lead screw 31 are respectively processed with left-handed and right-handed threads, and each thread is connected with a lead screw nut 32; the lead screw nut 32 passes through the circular brush disc 1 and is fixedly connected to the clamping block 4 at the corresponding position. The tensioning mechanism 5 includes a connecting plate 51 with a square structure and four curved connecting rods 52. The connecting plate 51 is rotatably connected to the mounting sleeve 2. The four corners of the connecting plate 51 are rotatably connected to one end of the curved connecting rod 52, and the other end of the curved connecting rod 52 is connected to the clamping block 4. The principle of the tensioning movement is: the rotation of the bidirectional lead screw 31 drives the lead screw nuts 32 at both ends to perform linear motion in opposite or opposite directions, and the lead screw nuts 32 drive the corresponding clamping blocks 4 to perform linear motion in opposite or opposite directions, the clamping blocks 4 drive the corresponding curved connecting rods 52 to move, the curved connecting rods 52 drive the connecting plate 51 to rotate, the connecting plate 51 drives the other two curved connecting rods 52 to move, and the curved connecting rods 52 drive the other two clamping blocks 4 to move, thereby realizing the tensioning movement of the two-way lead screw 31 driving the four clamping blocks 4 to synchronously approach or move away from the center of the circular brush plate 1.

[0042] In order to prevent the connecting plate 51 from rotating excessively and causing the slider 62 to deviate from the track, a limiting protrusion 53 is provided on the connecting plate 51, and a limiting ring 54 is provided on the above-mentioned mounting sleeve 2 to limit the rotation range of the connecting plate 51 relative to the mounting sleeve 2. By limiting the rotation range, the effect of limiting the adjustable range of the diameter is achieved, and the pressing block 4 is prevented from shrinking excessively, so that the steel wire on it shrinks into the circular brush disc 1, affecting the cleaning effect. Furthermore, two limiting rings 54 can be set, and the rotation range can be adjusted by controlling the setting distance of the two limiting rings 54, so that different rotation ranges can be limited according to actual needs.

[0043] In order to ensure the effect of pressing the steel wire. The pressing block 4 includes a connecting plate 41, a pressing groove 42, a cover plate 43 and a pressing bolt 45; the pressing groove 42 is fixed on the connecting plate 41, and the cover plate 43 is connected with the pressing groove 42 to form a steel wire fixing groove, and the steel wire fixing groove is used to fix the steel wire. A pressing plate 44 is provided below the cover plate 43, and a bolt hole is opened on the cover plate 43. The pressing bolt 45 passes through the bolt hole to press the pressing plate 44 to adjust the height of the steel wire fixing groove. The steel wire is made of stainless steel. The bolt hole on the cover plate 43 allows the pressing bolt 45 to pass through and press the pressing plate 44. This design allows the height of the steel wire fixing groove to be adjusted to accommodate different amounts of steel wire fixation.

[0044] In order to ensure tightness of the pressing, the width of the pressing plate 44 is equal to the width of the pressing groove 42 .

[0045] In order to enhance the stability of the tensioning mechanism 5, two connecting plates 51 are provided, and each of the four corners of the connecting plates 51 is provided with a first connecting hole, and correspondingly includes four cylindrical pins 55, which pass through the connecting hole of one connecting plate 51, the pin hole and the connecting hole of another connecting plate 51 to achieve a rotatable connection between the connecting plate 51 and the curved connecting rod 52. First, the rotatable connection between the connecting plate 51 and the curved connecting rod 52 is achieved through the cylindrical pins 55, which improves the flexibility of the structure. The design of the two connecting plates 51 enhances the stability of the overall structure.

[0046] Since the brush disc assembly is made of stainless steel and the circular brush disc 1 has a certain thickness, in order to reduce the weight of the brush disc assembly, a plurality of weight-reducing holes 7 are provided on the circular brush disc 1 .

[0047] In order to protect the driving mechanism 3 on the back of the circular brush disc 1, a supporting column 8 is provided on the back of the circular brush disc 1; this also facilitates the transportation and storage of the brush disc assembly.

[0048] In order to facilitate the movement of the brush disc assembly, two handles 9 are detachably connected to the front of the circular brush disc 1. The handles 9 are assembled during installation and removed during use.

[0049] The diameter of the brush plate assembly of this solution can be adjusted as needed to adapt to the cleaning of different types of steel crucibles. This adjustable diameter design solves the problems of high cost, heavy workload and low cleaning efficiency of traditional fixed-specification brush plate tools, and improves the flexibility and efficiency of cleaning work.

[0050] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
