Description

Technical Field

[0001] This utility model relates to the field of isolation cover technology, specifically a dustproof isolation cover device for metal processing. Background Technology

[0002] Metal processing, as a core link in manufacturing, encompasses diverse processes such as turning, milling, grinding, and welding, and widely serves high-end fields such as automotive parts, aerospace, and mold manufacturing. In these processes, the intense interaction between high-speed rotating cutting tools and metal workpieces generates a large amount of heterogeneous dust. This dust is not only an inevitable byproduct of the production process but has also become a key bottleneck restricting the industry's development.

[0003] Application number CN202122822682.2 discloses a dustproof device for a diamond grinding apparatus, relating to the field of diamond grinding equipment. It includes a grinding disc and a clamping device disposed outside the grinding disc for holding diamonds. It also includes a dust cover, which is a plate-shaped dust cover positioned above the grinding disc. The outer edge of the dust cover has a bent portion extending to one side, and the dust cover has a through-groove for the clamping device to pass through and move. The cover isolates the grinding dust from the outside environment, while the through-groove provides space for the clamping device to move, thus preventing dust from scattering off the worktable without obstructing the movement of the clamping device.

[0004] When grinding diamond workpieces of different sizes and shapes, the size and movement trajectory of the clamping device will change, and the fixed-specification slot may not be suitable. To adapt to workpieces of multiple specifications, dust covers with slots of different sizes need to be replaced, which not only increases the cost of equipment replacement, but also requires frequent shutdowns for replacement, reducing production efficiency. It cannot meet the processing needs of multiple varieties and small batches in mass production, and its applicable scenarios are obviously limited. Utility Model Content

[0005] The purpose of this utility model is to provide a dustproof isolation cover device for metal processing, which solves the problem of limited applicability and difficulty in adapting to workpieces of various specifications.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a dustproof isolation cover device for metal processing, comprising a dustproof cover body and a clamping assembly. The clamping assembly is installed on the bottom inner wall of the dustproof cover body. The dustproof cover body includes an arc-shaped base, with a mounting groove and a positioning ring frame in the middle of the arc-shaped base. A sliding groove is provided at the center of the arc-shaped base and communicates with the mounting groove. A metal sleeve is provided inside the positioning ring frame and is slidably connected to the inner wall of the sliding groove. Fixing blocks are provided on the inner walls of the arc-shaped base on both sides of the metal sleeve. Tension springs are fixedly connected between the metal sleeve and the two fixing blocks. A rubber ring is fitted inside the metal sleeve. A fixing plate is provided on one inner wall of the arc-shaped base and is vertically threaded with an adjustable screw. The adjustable screw is located in the middle of the two fixing blocks, and one end of the adjustable screw extends to the bottom side of the metal sleeve and is fixedly connected.

[0007] The purpose of this setup is that, before metal processing, the metal workpiece to be processed is placed in the mounting groove in the middle of the arc-shaped base, passing through the center of the positioning ring frame, so that one side of the workpiece is close to the inner wall of the rubber ring. At this time, the rubber ring is fixedly fitted inside the metal sleeve, and the bottom of the metal sleeve is slidably connected to the sliding groove of the arc-shaped base. The fixing blocks on both sides of the inner wall of the arc-shaped base are connected to the metal sleeve through tension springs to provide a restoring force for subsequent adjustments. The operator rotates the adjustable screw, which vertically penetrates the fixing plate on one side of the inner wall of the arc-shaped base. Because it is threaded with the fixing plate, it is pushed horizontally toward the metal sleeve when rotated. Since one end of the adjustable screw is fixed to the bottom of the metal sleeve, the linear movement of the screw directly drives the metal sleeve to slide along the slide groove toward the workpiece, and the tension spring is stretched synchronously to generate a reverse tension. As the metal sleeve continues to approach the workpiece, the rubber ring inside first contacts the workpiece surface on the side facing the workpiece. As the adjustable screw continues to rotate, the thrust applied by the metal sleeve is concentrated on that side of the rubber ring, causing elastic deformation on one side of the rubber ring. The deformed part is tightly attached to the outer wall of the workpiece, while the other side remains fixed due to the restriction of the inner wall of the metal sleeve, forming a "one-sided compression clamping" fixing effect. When the clamping force generated by the deformation of the rubber sleeve is sufficient to fix the workpiece, stop rotating the adjustable screw. At this time, the reverse tension of the tension spring and the pushing force of the adjustable screw are balanced, the metal sleeve is locked in the groove, and the deformation state of the rubber sleeve on one side is stable. This not only avoids the metal sleeve from directly contacting the workpiece and causing scratches, but also precisely adapts to the shape of the workpiece through unilateral extrusion, preventing the workpiece from sliding laterally during processing. Finally, the workpiece is positioned and clamped on the arc-shaped base, laying the foundation for the processing tool to be inserted.

[0008] Furthermore, the dust cover body includes a dust cover and a top frame, the bottom end of the dust cover is fixedly connected to the top edge of the arc-shaped base, and the top end of the dust cover is fixedly connected to the bottom edge of the top frame. The purpose of this setup is that, during device assembly, the bottom of the dust cover is first welded and fixed to the top edge of the arc-shaped base, and then the bottom edge of the top frame is bolted to the top of the dust cover, so that the main body of the dust cover forms a closed dustproof space of "arc-shaped base + dust cover + top frame".

[0009] Furthermore, the dust cover has a machining groove on its side wall.

[0010] The purpose of this design is that during the use of this device, when metal processing is performed, processing tools such as milling cutters, grinding wheels, and welding guns need to extend into the dust cover body through the processing groove and directly act on the workpiece that is clamped and fixed on the arc-shaped base.

[0011] Furthermore, the top frame has ventilation openings around the mounting frame, and the ventilation openings at the top of the top frame are covered with ventilation filter screens.

[0012] The purpose of this design is to draw the hot air generated during processing upwards through the vents while simultaneously drawing in filtered cool air through the ventilation filter cover, thereby cooling the dustproof space and preventing the workpiece from deforming due to high temperatures and affecting processing accuracy.

[0013] Furthermore, a cooling fan is installed at the middle mounting bracket of the top frame, and the fan blades of the cooling fan correspond to the lower part of the top frame.

[0014] The purpose of this design is to activate the cooling fan on the central mounting frame of the top frame during the processing of the device. The fan blades are directed towards the dustproof space below the top frame, and the fan speeds up the internal airflow when it rotates.

[0015] Furthermore, the cooling fan is positioned directly above the positioning ring.

[0016] The purpose of this design is that, during the use of the device, since the cooling fan is installed directly above the positioning ring frame, the fan airflow can act vertically on the workpiece clamping area, quickly removing the heat generated during processing, preventing the rubber ring from aging due to high temperature, and preventing the workpiece from thermally deforming and affecting the clamping stability.

[0017] This utility model has the following beneficial effects: (1) By setting up a tension spring, a rubber ring and a metal sleeve, the adjustable screw is rotated and the thrust applied by the metal sleeve causes the rubber ring to undergo elastic deformation on one side. The reverse tension of the tension spring and the thrust of the adjustable screw are balanced with each other. The deformed part is tightly attached to the outer wall of the workpiece, while the other side is fixed due to the restriction of the inner wall of the metal sleeve, thus forming a "single-sided squeezing and clamping" fixing effect.

[0018] (2) By setting up a cooling fan and a filter screen, the hot air generated during processing is drawn upward from the ventilation opening, while the filtered cold air is drawn in from the ventilation filter screen, thus achieving cooling in the dustproof space. The fan airflow can act vertically on the workpiece clamping area, quickly removing the heat generated during processing, avoiding the rubber ring from aging due to high temperature, and preventing the workpiece from thermally deforming and affecting the clamping stability.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4As shown, this utility model is a dustproof isolation cover device for metal processing, including a dustproof cover body 1 and a clamping assembly 2. The clamping assembly 2 is installed on the bottom inner wall of the dustproof cover body 1. The dustproof cover body 1 includes an arc-shaped base 101. The arc-shaped base 101 has a mounting groove in the middle and a positioning ring frame 107. The arc-shaped base 101 has a sliding groove 108 at its center, which communicates with the mounting groove. The positioning ring frame 107 has a metal sleeve 203 inside, which is slidably connected to the inner wall of the sliding groove 108. The arc-shaped base 101 has fixing blocks 204 on the inner walls of both sides of the metal sleeve 203. Tension springs 205 are fixedly connected between the metal sleeve 203 and the fixing blocks 204 on both sides. A rubber ring 201 is fitted inside the metal sleeve 203. A fixing plate 109 is provided on one inner wall of the arc-shaped base 101 and an adjustable screw 202 is vertically threaded to it. The adjustable screw 202 is located in the middle of the fixing blocks 204 on both sides. One end of the adjustable screw 202 extends to the bottom side of the metal sleeve 203 and is fixedly connected.

[0024] The purpose of this setup is that, before metal processing operations, the metal workpiece to be processed is placed in the mounting groove in the middle of the arc-shaped base 101, passing through the center of the positioning ring frame 107, so that one side of the workpiece is close to the inner wall of the rubber ring 201. At this time, the rubber ring 201 is fixedly fitted inside the metal sleeve 203, and the bottom of the metal sleeve 203 is slidably connected to the sliding groove 108 of the arc-shaped base 101. The fixing blocks 204 on both sides of the inner wall of the arc-shaped base 101 are connected to the metal sleeve 203 through the tension spring 205, providing a restoring force for subsequent adjustments. The operator rotates the adjustable screw 202, which vertically penetrates the fixing plate 109 on one side of the inner wall of the arc-shaped base 101. Because it is threadedly matched with the fixing plate 109, it is pushed horizontally toward the metal sleeve 203 when rotated. Since one end of the adjustable screw 201 is fixed to the bottom side of the metal sleeve 203, the linear movement of the screw directly drives the metal sleeve 203 to slide along the slide groove 108 toward the workpiece, and the tension spring 205 is stretched synchronously to generate a reverse tension force. As the metal sleeve 203 continues to approach the workpiece, the rubber ring 201 inside it first contacts the workpiece surface on the side facing the workpiece. As the adjustable screw 202 continues to rotate, the thrust applied by the metal sleeve 203 is concentrated on that side of the rubber ring 201, causing the rubber ring 201 to undergo elastic deformation on one side. The deformed part is tightly attached to the outer wall of the workpiece, while the other side remains fixed due to the restriction of the inner wall of the metal sleeve 203, forming a "single-sided compression clamping" fixing effect. When the clamping force generated by the deformation of the rubber sleeve 201 is sufficient to fix the workpiece, the adjustable screw 202 is stopped from rotating. At this time, the reverse tension of the tension spring 205 and the pushing force of the adjustable screw 202 are balanced. The metal sleeve 203 is locked in position within the slide groove 108. The deformation state of the rubber sleeve 201 on one side is stable, which not only avoids the metal sleeve 203 from directly contacting the workpiece and causing scratches, but also precisely adapts to the shape of the workpiece through unilateral extrusion, preventing the workpiece from sliding laterally during processing. Finally, the workpiece is positioned and clamped on the arc-shaped base 101, laying the foundation for the processing tool to extend into the workpiece.

[0025] The dust cover body 1 includes a dust cover 102 and a top frame 103. The bottom end of the dust cover 102 is fixedly connected to the top edge of the arc-shaped base 101, and the top end of the dust cover 102 is fixedly connected to the bottom edge of the top frame 103. The purpose of this arrangement is that, during device assembly, the bottom end of the dust cover 102 is first welded and fixed to the top edge of the arc-shaped base 101, and then the bottom edge of the top frame 103 is bolted to the top of the dust cover 102, so that the dust cover body 1 forms a closed dustproof space of "arc-shaped base + dust cover + top frame".

[0026] The dust cover 102 has a machining groove 104 on its side wall.

[0027] The purpose of this design is that during the use of the device, when metal processing is performed, processing tools such as milling cutters, grinding wheels, and welding guns need to extend into the dust cover body 1 through the processing groove 104 and directly act on the workpiece that is clamped and fixed on the arc-shaped base 101.

[0028] The top frame 103 has ventilation openings around the mounting frame, and the ventilation openings at the top of the top frame 103 are covered with ventilation filter screens 105.

[0029] The purpose of this setup is to draw the hot air generated during processing upwards through the vents while simultaneously drawing in filtered cool air through the ventilation filter cover 105, thereby cooling the dustproof space and preventing the workpiece from deforming due to high temperatures and affecting processing accuracy.

[0030] A cooling fan 106 is installed at the middle mounting bracket of the top frame 103, and the blades of the cooling fan 106 correspond to the lower part of the top frame 103.

[0031] The purpose of this arrangement is that during the use of the device, the cooling fan 106 of the mounting bracket in the middle of the top frame 103 is activated during the processing. The fan blades are directed towards the dustproof space below the top frame 103, and the internal airflow is accelerated when the fan rotates.

[0032] The cooling fan 106 is located directly above the positioning ring 107.

[0033] The purpose of this arrangement is that, during the use of the device, since the cooling fan 106 is installed directly above the positioning ring frame 107, the fan airflow can act vertically on the workpiece clamping area, quickly removing the heat generated during processing, preventing the rubber ring 201 from aging due to high temperature, and preventing the workpiece from thermally deforming and affecting the clamping stability.

[0034] Before using the dustproof isolation cover device for metal processing, the assembly should be completed first: the dust cover 102 is fixed at both ends to the arc-shaped base 101 and the top frame 103 respectively, the ventilation opening of the top frame 103 is equipped with a ventilation filter screen 105, the middle is equipped with a cooling fan 106 and aligned with the positioning ring frame 107, the fixing plate 109 is fixed on one side of the arc-shaped base 101, the adjustable screw 202 passes through the fixing plate 109 and connects to the metal sleeve 203, the metal sleeve 203 is fitted with the rubber ring 201 and then enters the slide groove 108, and the tension springs 205 and the fixing blocks 204 are connected on both sides; When the operation starts, the operator puts the workpiece through the positioning ring frame 107 into the installation groove, so that one side of the workpiece is close to the rubber ring 201. The operator rotates the adjustable screw 202, which drives the metal sleeve 203 to slide along the slide groove 108 toward the workpiece. The tension spring 205 is stretched and the metal sleeve 203 continues to advance, squeezing the side of the rubber ring 201 facing the workpiece, causing it to undergo elastic deformation and tightly adhere to the outer wall of the workpiece, forming a unilateral clamping force. After the clamping is stable, the operator stops rotating the screw. Next, the cooling fan 106 is turned on. After the outside air is filtered by the ventilation filter screen 105, it enters the dust cover body 1. The hot air inside is extracted to maintain a suitable processing temperature. The operator holds the processing tools and extends them into the processing groove 104 of the dust cover 102 to perform milling, grinding and other processing on the workpiece. The dust is sealed in the dustproof space. After processing, the adjustable screw 202 is rotated in the opposite direction, the tension spring 205 pulls the metal sleeve 203 to reset, the rubber ring 201 deforms and separates from the workpiece, and the operator takes out the workpiece from the positioning ring frame 107. If continuous operation is required, the process of "workpiece loading → screw pushing sleeve → squeezing rubber ring deformation clamping → fan starting → processing → reset and take out" is repeated to take into account the fixation accuracy, dust prevention and cooling, and ensure processing efficiency.
