[0015] The present invention has the following beneficial effects:

[0016] (1) According to the present invention, when using the device, firstly, the positioning rail on the fixed plate is placed in the anti-corrosion tank, the positioning rail is adjusted so that the welded weld is between the two positioning rails, the screw rod is rotated to make the clamping plate rise, so that the clamping plate is close to the outer wall of the anti-corrosion tank, such a setting is conducive to fixing the positioning rail on the inner wall of the anti-corrosion tank, then the device is placed in the anti-corrosion tank, and the sliding block directly below the extrusion rod in the device shell is placed on the two positioning rails so that the sliding block can slide stably on the top of the positioning rail, thereby facilitating the grinding parts of the device to accurately grind the weld, after the positioning mechanism is installed and fixed, the operating handle on the device shell is pushed so that the working parts of the device can slide stably along the positioning rail, at this time, the extrusion rod can be contracted by pressing the operating handle, and the height of the impact mechanism and the transmission mechanism can be controlled by the contraction of the extrusion rod, thereby facilitating the adjustment of the height of the weld treatment according to the height of the welding slag.

[0017] (2) According to the present invention, after the positioning mechanism is installed, the driving motor is started, and the rotation of the driving motor drives the impact box on the output shaft to rotate. The rotation of the impact box drives the impact heads at the bottom of the sliding rods on the impact box to rotate. When the impact head rotates to the bottom of the impact box and contacts the weld on the inner wall of the anti-corrosion tank, the sliding rod above the impact head will be squeezed into the impact box due to the protrusion of the welded weld. At this time, the impact head collides with the welded weld, so that the welding slag on the weld is separated from the weld, which has the beneficial effect of knocking the welding slag and separating the welding slag. When the impact head directly contacts the welding slag, due to the excessive rotation speed of the impact box, if the impact head directly contacts the welding slag, it may damage the anti-corrosion tank body due to excessive impact force. By setting a buffer spring, when the impact head contacts the welding slag, the impact head will rotate at one end of the sliding rod and stretch the buffer spring, thereby having a friendly effect of buffering the force release, thereby preventing the impact head from damaging the anti-corrosion tank body.

[0018] (3) In the present invention, when the output shaft rotates, the transmission belt is driven to rotate, the rotation of the transmission belt drives the grinding wheel to rotate, the rotation of the grinding wheel drives the grinding ring on the extrusion block at one end of the telescopic rod to rotate, the grinding ring rotates and grinds the raised part of the weld at the bottom, when the raised part encounters the grinding ring on the grinding wheel, the raised part squeezes the extrusion block in the grinding ring to slide inward along the groove, this arrangement is conducive to the grinding ring grinding the raised part inside the grinding wheel, thereby avoiding the grinding ring grinding the anti-corrosion tank body, and improving the safety of the grinding of the device; by setting a reciprocating mechanism, the rotation of the output shaft drives the crank to rotate, and the rotation of the crank drives the pulling rod to The pulling rod will pull the sliding frame at the other end of the pulling column to slide back and forth along the fixed column. This arrangement is conducive to increasing the frequency of contact between the grinding ring on the grinding wheel and the weld, and is conducive to speeding up the grinding rate of the raised part of the weld. On the other hand, the reciprocating motion is conducive to quickly cleaning the welding slag between the grinding ring and the weld, thereby improving the grinding quality of the grinding ring. In addition, by setting a transmission mechanism, when the fixed column reciprocates, in order to avoid the transmission belt from loosening, auxiliary shafts 1 and 2 connected by transmission are set on the transmission belt, which is conducive to the auxiliary shaft 3 to continuously squeeze the transmission belt, so that the transmission belt is always taut, thereby improving the transmission efficiency.

[0019] (4) The present invention sets a cooling mechanism. The impact box rotates to drive the impact heads at the bottom of several sliding rods on the impact box to rotate. When the impact head rotates to the bottom of the impact box and contacts the weld on the inner wall of the anti-corrosion tank, the protrusion of the welded weld will squeeze the sliding rod above the impact head into the impact box. The sliding rod is squeezed and drives the sliding block 2 to squeeze the squeezing spring along the sliding groove 2. The sliding block 2 slides and drives the pushing ring at one end of the linkage rod to squeeze the linkage plate. The linkage plate is squeezed and slides along the output shaft. The linkage plate moves and squeezes the pressure spring on the inflation cylinder, so that the gas inside the inflation cylinder passes through the inside of the grinding wheel and is discharged through the exhaust groove. This arrangement is conducive to accelerating the air flow around the grinding circle on the grinding wheel, so that the air can quickly take away the high temperature generated by the grinding circle. On the one hand, it is conducive to the airflow to take away the welding slag on the surface of the grinding circle, which is conducive to improving the quality of weld grinding. On the other hand, it is conducive to cooling the grinding circle and increasing the service life of the grinding circle.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The positioning mechanism 2 includes a sliding groove 201 provided on the side wall of the fixed plate 14, the inner wall of the sliding groove 201 is slidably connected with a clamping plate 202, the end of the clamping plate 202 close to the fixed plate 14 is rotatably connected with a screw rod 203, the side of the fixed plate 14 close to the equipment housing 1 is fixedly connected with a plurality of positioning slide rails 204, the fixed column 15 is rotatably connected with a plurality of extrusion rods 205, the end of the extrusion rod 205 away from the fixed column 15 is fixedly connected with a sliding block 206, the sliding block 206 is slidably connected with the positioning slide rail 204, the function of this component is to first put the positioning slide rail 204 on the fixed plate 14 into the anti-corrosion tank, adjust the positioning slide rail 204 so that the welded weld is between the two positioning slide rails 204, rotate the screw rod 203 to make the clamping plate 202 rise, so that the clamping The plate 202 is close to the outer wall of the anti-corrosion tank. This arrangement is conducive to fixing the positioning slide rail 204 on the inner wall of the anti-corrosion tank. At this time, the device is placed inside the anti-corrosion tank, and the sliding block 206 just below the extrusion rod 205 in the equipment housing 1 is placed on the two positioning slide rails 204 so that the sliding block 206 can slide stably above the positioning slide rails 204, thereby facilitating the grinding parts of the device to accurately grind the welds. After the positioning mechanism 2 is installed and fixed, the operating handle 11 on the equipment housing 1 is pushed so that the working parts of the device can slide stably along the positioning slide rail 204. At this time, the extrusion rod 205 can be contracted by pressing the operating handle 11.

At this time, the impact head 306 collides with the welded weld, so that the welding slag on the weld is separated from the weld, which has the beneficial effect of knocking the welding slag and separating the welding slag.

This arrangement is conducive to accelerating the air flow around the grinding circle 507 on the grinding wheel 503, so that the air can quickly take away the high temperature generated by the grinding circle 507. On the one hand, it is conducive to the airflow to take away the welding slag on the surface of the grinding circle 507, which is conducive to improving the welding quality of the weld. On the other hand, it cools down the grinding circle 507 and increases the service life of the grinding circle 507.

[0045] A specific application of this embodiment is:

[0046] When using the device, first put the positioning rail 204 on the fixing plate 14 into the anti-corrosion tank, adjust the positioning rail 204 so that the welded weld is between the two positioning rails 204, rotate the screw rod 203 to make the clamping plate 202 rise, so that the clamping plate 202 is close to the outer wall of the anti-corrosion tank. This arrangement is conducive to fixing the positioning rail 204 on the inner wall of the anti-corrosion tank. At this time, put the device into the anti-corrosion tank, and put the sliding block 206 just below the extrusion rod 205 in the device housing 1 on the two positioning rails 204 so that the sliding block 206 It can slide stably on the positioning slide rail 204, so that the grinding parts of the device can grind the weld seam accurately. After the positioning mechanism 2 is installed and fixed, the operating handle 11 on the device housing 1 is pushed so that the working parts of the device can slide stably along the positioning slide rail 204. At this time, the squeezing rod 205 can be contracted by pressing the operating handle 11. The height of the impact mechanism 3 and the transmission mechanism 4 can be controlled by the contraction of the squeezing rod 205, so that the height of the weld seam processing can be adjusted according to the height of the welding slag. After the positioning mechanism 2 is installed, The driving motor 12 is started, and the driving motor 12 rotates to drive the impact box 301 on the output shaft 13 to rotate. The rotation of the impact box 301 drives the impact head 306 at the bottom of the plurality of sliding rods 305 on the impact box 301 to rotate. When the impact head 306 rotates to the bottom of the impact box 301 and contacts the weld on the inner wall of the anti-corrosion tank, the sliding rod 305 above the impact head 306 is squeezed into the impact box 301 due to the protrusion of the welded weld. At this time, the impact head 306 collides with the welded weld, so that the welding slag on the weld is separated from the weld. The gap has the beneficial effect of striking the welding slag and making the welding slag separate. When the impact head 306 directly contacts the welding slag, since the impact box 301 rotates too fast, if the impact head 306 directly contacts the welding slag, the impact force may be too large, thereby damaging the anti-corrosion tank body. By setting the buffer spring 307, when the impact head 306 contacts the welding slag, the impact head 306 will rotate at one end of the sliding rod 305 and stretch the buffer spring 307, thereby playing a friendly effect of buffering the release of force, thereby preventing the impact head 306 from damaging the anti-corrosion tank body;

[0047] In addition, when the output shaft 13 rotates, the transmission belt 401 is driven to rotate, and the rotation of the transmission belt 401 drives the grinding wheel 503 to rotate. The rotation of the grinding wheel 503 drives the grinding ring 507 on the extrusion block 506 at one end of the telescopic rod 504 to rotate. The grinding ring 507 rotates and grinds the raised part of the weld at the bottom. When the raised part encounters the grinding ring 507 on the grinding wheel 503, the raised part squeezes the extrusion block 506 in the grinding ring 507 to slide inward along the groove. This arrangement is conducive to the grinding ring 507 grinding the raised part inside the grinding wheel 503, thereby preventing the grinding ring 507 from grinding the anti-corrosion tank body, thereby improving the safety of the grinding device. The output shaft 13 rotates to drive the crank 601 to rotate, and the rotation of the crank 601 drives the pull rod 602 to move regularly. The pull rod 602 will pull the sliding frame 501 at the other end of the pulling column 603 to slide back and forth along the fixed column 15. This arrangement is conducive to increasing the frequency of contact between the grinding ring 507 on the grinding wheel 503 and the weld. This arrangement is conducive to accelerating the grinding rate of the raised part of the weld. On the other hand, the reciprocating motion is conducive to quickly cleaning the welding slag between the grinding ring 507 and the weld, thereby improving the grinding quality of the grinding ring 507. In addition, by setting the transmission mechanism 4, in order to avoid the loosening of the transmission belt 401 when the fixed column 15 reciprocates, a transmission belt 401 is provided. The auxiliary shaft 1 402 and the auxiliary shaft 2 403 are connected in transmission, which is beneficial for the auxiliary shaft 3 405 to continuously squeeze the transmission belt 401, so that the transmission belt 401 is always taut, thereby improving the transmission efficiency; by setting the cooling mechanism 7, the collision box 301 rotates to drive the collision head 306 at the bottom of the plurality of sliding rods 305 on the collision box 301 to rotate, and when the collision head 306 rotates to the bottom of the collision box 301 and contacts the weld on the inner wall of the anti-corrosion tank, due to the protrusion of the welded weld, the sliding rod 305 above the collision head 306 will be squeezed into the collision box 301, and the sliding rod 305 is squeezed to drive the sliding block 2 303 to squeeze the squeezing spring 304 along the sliding groove 2 302, and the sliding block The sliding of the second 303 drives the pushing ring 702 at one end of the linkage rod 701 to squeeze the linkage plate 703. The linkage plate 703 is squeezed and slides along the output shaft 13. The linkage plate 703 moves and squeezes the pressure spring 707 on the inflation cylinder 705, so that the gas inside the inflation cylinder 705 passes through the inside of the grinding wheel 503 and is discharged through the exhaust groove 708. This arrangement is conducive to accelerating the air flow around the grinding circle 507 on the grinding wheel 503, so that the air can quickly take away the high temperature generated by the grinding circle 507. On the one hand, it is conducive to the airflow to take away the welding slag on the surface of the grinding circle 507, which is conducive to improving the welding quality of the weld. On the other hand, it cools down the grinding circle 507 and increases the service life of the grinding circle 507.
