Description

Technical Field

[0001] The invention belongs to the technical field of dial processing, in particular to a dial cutting device for producing pressure gauges. Background Art

[0002] Pressure gauges play an indispensable role in many areas of industrial production, scientific research experiments and daily life. They are used to measure and display various pressure values. They are key instruments to ensure the normal operation of equipment, production safety and scientific research. The dial is one of the important components on the pressure gauge. During the production and processing of the dial, it will be cut into a suitable size for use through a cutting device.

[0003] In the prior art, the dial is cut by pressing the cutting knife downwards with an upper hydraulic rod, and only a limited number of dials can be cut at a time. In large-scale production scenarios, the cutting action needs to be repeated frequently, which consumes a lot of time and manpower costs. After the cutting is completed, the cutting knife inevitably produces burrs on the edge of the dial when cutting the material, and the dial needs to be transferred to a special deburring equipment for secondary processing. This not only increases the processing steps, but also involves the transportation and positioning of the dial between different equipment. The entire process is cumbersome and complicated, which greatly prolongs the processing cycle of the dial and reduces production efficiency.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The present invention is designed with a cutting and grinding mechanism, which is equipped with multiple sets of cutting knives and multiple sets of external gear discs, and can cut multiple dial bodies at a time. Compared with the traditional method of cutting a small number of dials at a time, the cutting efficiency is effectively improved, and the deburring component is integrated into the mechanism. After cutting, the edge of the dial body can be subjected to multiple deburring treatments by the deburring knife and the grinding column, which reduces the process of transferring the dial to a special deburring device, shortens the processing time, and improves the overall processing efficiency. At the same time, the distance between the cutting knives and the grinding column and the dial body can be adjusted according to the different sizes of the dial body, which is convenient for deburring the outer wall of the dial body.

[0023] (2) The present invention combines the designed L-shaped plate, sandpaper, movable frame, moving plate, circular frame, inclined plate, L-shaped frame, upper spring, nut seat, connecting column, second bidirectional screw and reduction motor. The sandpaper is fixed on the inner wall of the connecting belt and can fit the outer wall of the dial body. When the rotating component drives the dial body to rotate, the burrs on the edge of the dial body are effectively ground, thereby improving the deburring effect. Through the cooperation of the second bidirectional screw and the nut seat, the sandpaper can be driven to open or shrink, and can contact and adapt to dial bodies of different sizes, thereby enhancing versatility. Moreover, when the sandpaper moves downward and approaches the cut dial body, it contacts the inclined plate through the connecting column and can move the sandpaper toward the dial body through the inclined surface on the inclined plate, thereby increasing the fit between the sandpaper and the dial body, thereby increasing the deburring effect of the sandpaper on the outside of the dial body.

[0024] (3) The present invention uses a designed limit piece to clamp and limit the first bidirectional screw during use, thereby preventing the first bidirectional screw from being affected by vibration and accidentally rotating during the deburring process, causing the deburring knife and the grinding column to move, and affecting the deburring effect on the edge of the outer wall of the dial body.

[0048] Example 2

[0049] Based on Example 1, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4The rotating assembly includes a chassis 200 and multiple sets of outer gear discs 203 rotatably arranged on the mounting frame 100. Multiple sets of rotating tubes 207 are rotatably arranged on the top of the chassis 200. When the outer gear discs 203 rotate, the rotating tubes 207 and the chassis 200 below are driven to rotate and be in a connected state. The negative pressure port and the negative pressure support platform 210 are provided with negative pressure by the negative pressure machine in the negative pressure device. The outer gear disc 203 is fixed to the top of the rotating tube 207. A lower bearing 206 is provided between the bottom of the chassis 200 and the mounting frame 100.

[0050] A negative pressure support platform 210 is fixedly provided on the top of the outer gear disc 203, and the dial body 102 is located on the top of the negative pressure support platform 210. An air guide slip ring 211 is provided on the outside of the rotating tube 207. The air guide slip ring 211 consists of a rotating end and a stationary end. The rotating end is connected to the rotating tube 207, and the stationary end is connected to the interior of the chassis 200 through a connecting pipe. A connecting pipe is fixedly provided between the air guide slip ring 211 and the interior of the chassis 200. Multiple groups of negative pressure ports are provided on the outer gear disc 203, and a dust removal device 202 is fixedly provided at the bottom of the chassis 200. A negative pressure machine is installed inside the dust removal device 202. When the negative pressure machine is turned on, negative pressure can be generated on the top of the negative pressure support platform 210 and the multiple groups of negative pressure ports, which can adsorb and limit the dial body 102 and the excess parts after cutting. Dust generated during cutting and grinding will be sucked into the dust removal device 202 by the negative pressure port for purification.

[0051] A first electric push rod 209 is fixedly provided at the bottom of the chassis 200 , a driving motor 208 is fixedly provided at the working end of the first electric push rod 209 , a driving gear 201 is fixedly provided at the working end of the driving motor 208 , and the driving gear 201 can mesh with the outer gear disc 203 .

[0052] The present invention is designed with a cutting and grinding mechanism, which is equipped with multiple groups of cutting knives 204 and multiple groups of outer toothed discs 203, and can cut multiple dial bodies 102 at a time. Compared with the traditional method of cutting a small number of pieces at a time, the cutting efficiency is effectively improved, and the deburring component is integrated into the mechanism. After cutting, the edge of the dial body 102 can be subjected to multiple deburring treatments by the deburring knife 216 and the grinding column 217, which reduces the process of transferring the dial to a special deburring device, shortens the processing time, and improves the overall processing efficiency. At the same time, the spacing between the cutting knives 204 and the grinding column 217 and the dial body 102 can be adjusted according to the different sizes of the dial body 102, which is convenient for deburring the outer wall of the dial body 102.

[0053] In summary, during use, the dial body 102 to be cut is placed on the multiple sets of negative pressure support platforms 210. At this time, the negative pressure generated by the grooves on the negative pressure support platforms 210 adsorbs and limits it, and then the chassis 200 is driven to rotate by an external driving device. When it rotates to the bottom of the multiple sets of cutting shears 204, it stops rotating. Then, the upper frame 205 and the multiple sets of cutting shears 204 and the deburring blades 216, grinding column 217 and other structures below are driven to descend by the upper hydraulic rod 101. Then, the deburring blades 216 and grinding column 217 are lowered to the bottom of the dial body 102. The bottom of the cutting shears 204 contacts the upper surface of the dial body 102. Then, the first electric push rod 209 is turned on, and the working end drives the drive motor 208 and the upper The driving gear 201 moves to the left, and then the driving gear 201 approaches the corresponding outer toothed disc 203. At this time, the driving motor 208 is turned on and rotated slowly, driving the driving gear 201 to rotate a distance and then stop. At this time, the teeth on the outside of the driving gear 201 correspond to the tooth grooves on the outside of the outer toothed disc 203. Then, the first electric push rod 209 is used to push it to the left, and then the driving gear 201 is meshed with the outer toothed disc 203. Then, the driving motor 208 is turned on to drive the corresponding outer toothed disc 203 to rotate. Through this outer toothed disc 203, the remaining three groups of outer toothed discs 203 are driven to rotate. Then, the upper hydraulic rod 101 drives the multiple groups of cutting shears 204 to descend and start cutting the rotating dial body 102.

[0054] When the outer toothed disc 203 stops rotating after cutting, the excess part outside the dial body 102 falls through the multiple groups of negative pressure ports on the outer toothed disc 203 and under the action of gravity and is adsorbed and limited by the negative pressure ports, and then the upper hydraulic rod 101 drives the cutting knife 204, the deburring knife 216 and the grinding column 217 to move upward, and then the bottom of the cutting knife 204 is separated from the dial body 102, and the first bidirectional screw rod 212 on the rightmost side of the upper frame 205 is rotated. The first bidirectional screw rod 212 on the rightmost side indirectly drives the other multiple groups of first bidirectional screw rods 212 to rotate through the connecting rod 213. At this time, the two groups of nut blocks outside the first bidirectional screw rod 212 move in opposite directions, driving the external side frame 219 to move in opposite directions. The deburring blade 216 and the two sets of grinding cylinders 217 are moved in the same direction, and then the two sets of grinding cylinders 217 contact the outer wall of the dial body 102. At this time, since the deburring blade 216 continues to move toward the dial body 102, the grinding cylinders 217 and the ends of the rotating bar 220 are squeezed and rotated in the direction away from the grinding cylinders 217, driving the connecting spring 221 on the rotating bar 220 to start stretching until the deburring blade 216 contacts the outer wall of the dial body 102. At this time, the driving motor 208 is turned on to make the multiple sets of outer toothed discs 203 and the dial body 102 on the outer toothed disc 203 rotate accordingly. At this time, the deburring blade 216 and the two sets of grinding cylinders 217 can be used to deburr the outer wall of the dial body 102.

[0055] After the deburring is completed, the first bidirectional screw rod 212 is rotated in the opposite direction, and the two sets of nut blocks on the first bidirectional screw rod 212 move in the opposite direction, driving the deburring knife 216 and the two sets of grinding cylinders 217 to move away from the dial body 102 to their original positions. Subsequently, the cutting knife 204, the deburring knife 216 and the grinding cylinder 217 are driven to rise to their original positions by the upper hydraulic rod 101. Finally, the chassis 200 is opened again, driving the outer toothed disc 203 and the deburred dial body 102 to rotate to a front position close to the chassis 200. At this time, the deburred dial body 102 is forcibly taken out of the negative pressure support platform 210, and then other uncut dial bodies 102 are placed. During this period, the dial bodies 102 on the multiple sets of outer toothed discs 203 arranged in parallel on another set of chassis 200 rotate to under the multiple sets of cutting knives 204. This is repeated to complete the cutting and deburring of the dial body 102.

[0056] Example 3

[0057] Based on Example 2, please refer to Figure 1 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13 The deburring assembly includes a circular frame 405 and multiple groups of movable frames 403 slidably arranged inside the circular frame 405. The movement of the two groups of movable frames 403 in opposite directions can drive the opening of the sandpaper 402 to increase or decrease. A limiting motor 413 is fixed on the circular frame 405, and the bottom working end of the limiting motor 413 can extend to the surface of the second bidirectional screw rod 411, which can limit the second bidirectional screw rod 411 during use to prevent the reduction motor 412 from accidentally rotating and causing the position of the sandpaper 402 to move, affecting the deburring situation. A connecting belt is fixed between the ends of the two groups of movable frames 403, and the inner wall of the connecting belt is fixed with sandpaper 402, which is used to grind the burrs on the outer wall of the dial body 102;

[0058] Multiple sets of second bidirectional screw rods 411 are rotatably mounted on the circular frame 405. A connecting column 410 is fixedly mounted between two sets of second bidirectional screw rods 411. Nut seats 409 are disposed on the exterior of the second bidirectional screw rods 411. The two sets of nut seats 409 move toward or away from each other to drive the corresponding two sets of movable frames 403 to move. The nut seats 409 are fixed to the movable frames 403.

[0059] A reduction motor 412 is fixedly provided on one side of the circular frame 405 for driving the second bidirectional screw rod 411 to rotate, and a working end of the reduction motor 412 extends to the end of the second bidirectional screw rod 411 .

[0060] Two sets of hydraulic cylinders 400 are fixedly installed on the top of the circular frame 405. The bottom working ends of the hydraulic cylinders 400 are fixed to the top of the circular frame 405, and the hydraulic cylinders 400 are fixed to the movable plate 404. Two sets of L-shaped frames 407 are fixedly installed on the front of the upper frame 205. The bottom of the L-shaped frames 407 is fixedly installed with an inclined plate 406 for driving the sandpaper 402 towards or away from the cutting knife 204;

[0061] An L-shaped plate 401 is fixedly provided on the top of the upper frame 205, and a movable plate 404 is slidingly provided inside the L-shaped plate 401. The movable plate 404 can slide inside the L-shaped plate 401. An upper spring 408 is fixedly provided between one end of the movable plate 404 and the L-shaped plate 401, and the hydraulic cylinder 400 is fixed on the movable plate 404.

[0062] The present invention combines the designed L-shaped plate 401, sandpaper 402, movable frame 403, movable plate 404, circular frame 405, inclined plate 406, L-shaped frame 407, upper spring 408, nut seat 409, connecting column 410, second bidirectional screw rod 411 and reduction motor 412. The sandpaper 402 is fixed to the inner wall of the connecting belt and can fit the outer wall of the dial body 102. When the rotating assembly drives the dial body 102 to rotate, the burrs on the edge of the dial body 102 are effectively ground to improve the deburring effect. The cooperation between the screw rod 411 and the nut seat 409 can drive the sandpaper 402 to expand or contract, and can contact and adapt to dial bodies 102 of different sizes, thereby enhancing versatility. Moreover, when the sandpaper 402 moves downward and approaches the cut dial body 102, it contacts the inclined plate 406 through the connecting column 410 and the inclined surface of the inclined plate 406 can move the sandpaper 402 toward the dial body 102, thereby increasing the fit between the sandpaper 402 and the dial body 102, thereby increasing the deburring effect of the sandpaper 402 on the outside of the dial body 102.

[0063] In summary, after the dial body 102 on the multiple sets of outer toothed discs 203 rotates to below the multiple sets of cutting blades 204, the upper frame 205 is driven to descend by the upper hydraulic rod 101 until the bottom of the cutting blade 204 contacts the upper surface of the dial body 102, and then the multiple sets of outer toothed discs 203 rotate to drive the dial body 102 to rotate. At this time, the cutting blade 204 is cut by the upper hydraulic rod 101 as it continues to move downward. After cutting is completed, it moves up to a certain height and stops according to the above-mentioned reverse principle. Then, the hydraulic cylinder 400 drives the lower circular frame 405 to descend, driving the sandpaper 402 to move along with it. When the sandpaper 402 is about to approach the outer wall of the dial body 102, the circular frame 405 descends and brings the connecting column 410 down with it. During the descending process, it contacts the inclined surface on the inclined plate 406, and then the connecting column 410 drives The circular sandpaper 402 and the like move closer to the dial body 102, and then a part of the inner wall of the sandpaper 402 contacts the outer wall of the dial body 102, and then the second bidirectional screw rod 411 is driven to rotate by the reduction motor 412, and then the remaining multiple sets of second bidirectional screw rods 411 are indirectly driven to rotate through the connecting column 410. At this time, the two sets of nut seats 409 on the second bidirectional screw rod 411 move in opposite directions, driving the two sets of movable frames 403 to move. At this time, the sandpaper 402 and the connecting belt are opened to make them in a taut state, and then the outer toothed disk 203 is turned on to rotate and drive the dial body 102 to rotate, so that the outer wall of the dial body 102 is polished and deburred by the sandpaper 402. When the deburring is completed, the upper frame 205, the circular frame 405, etc. can be moved to their original positions according to the above-mentioned reverse principle.

[0064] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
