Summary of the Invention

[0005] The purpose of this invention is to provide a grouting sleeve pin welding conveying positioning and fixing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grouting sleeve pin welding conveying positioning and fixing device, comprising a material channel and a welding gun, wherein a support plate is fixedly connected to the bottom of the material channel, and a positioning mechanism is provided on the surface of the support plate.

[0007] The positioning mechanism includes a slide table, a positioning gripper 2 fixedly connected to the inner wall of the slide table, and a positioning gripper 1 slidably connected to the inner wall of the slide table. The inner walls of both the positioning gripper 1 and the positioning gripper 2 are arc-shaped surfaces for fitting the grouting sleeve and positioning the grouting sleeve.

[0008] According to the above technical solution, the bottom of the slide table is slidably connected to the surface of the support plate via a slide rail. The elastic push rod is used to support the positioning grabber and drive the positioning grabber to reset. The inner wall of the positioning grabber is rotatably connected to the guide wheel via a rotating shaft. The guide wheel is supported by the positioning grabber and contacts the outer wall of the grouting sleeve, and rolls along the outer wall of the grouting sleeve by friction. The guide wheel is used to support the grouting sleeve and prevent the positioning grabber from scratching the outer wall of the grouting sleeve. The outer wall of the slide table is fixedly connected to a guide plate, which is used to guide the grouting sleeve during the conveying process.

[0009] According to the above technical solution, the outer wall of the positioning grab is rotatably connected to the guide wheel 2 via a rotating shaft. The guide wheel 2 is supported by the positioning grab and contacts the outer wall of the grouting sleeve, and rolls along the outer wall of the grouting sleeve by friction. The guide wheel 2 is adjusted by contacting the outer wall of the grouting sleeve and by driving the positioning grab to slide on the inner wall of the slide table 1 through the diameter of the grouting sleeve, so that the inner wall of the positioning grab is in contact with the outer wall of the grouting sleeve. An infrared sensor is set at the end of the slide table 1 near the grouting sleeve to sense the position of the grouting sleeve.

[0010] According to the above technical solution, the material channel is driven by a servo motor to drive the transmission wheel to transport the grouting sleeve. A slide is fixedly connected to the outer wall of the material channel, and a cylinder is fixedly connected to the top of the slide. The output end of the cylinder is fixedly connected to the top of the welding gun. The slide is driven by a servo motor to adjust the welding gun along the X-axis, and the cylinder is used to drive the welding gun to adjust along the Z-axis.

[0011] According to the above technical solution, a second cylinder is fixedly connected to the outer wall of the material channel, and a clamping mechanism is provided on the inner wall of the first slide. The clamping mechanism includes the second slide. The outer wall of the second slide is fixedly connected to the output end of the second cylinder. The second cylinder is used to drive the second slide to slide on the inner wall of the first slide. A pressure block is fixedly connected to the outer wall of the second slide near the first positioning gripper. The outer wall of the pressure block slides along the guide groove wall. The pressure block is made of heat-resistant rubber and is used to contact and clamp the outer wall of the grouting sleeve through the support of the second slide.

[0012] According to the above technical solution, a support plate 2 is slidably connected to the inner wall of the slide table 2. The support plate 2 slides up and down along the inner wall of the slide table 2. A sliding groove 2 is opened on the outer wall of the support plate 2. A guide sleeve is slidably connected to the inner wall of the support plate 2. An adjusting block is slidably connected to the inner wall of the guide sleeve. A cylinder 3 is fixedly connected to the outer wall of the support plate 2. The output end of the cylinder 3 passes through the sliding groove 2 and is fixedly connected to the end of the adjusting block near the cylinder 3. The adjusting block is supported by the cylinder 3 and contacts the outer wall of the grouting sleeve pin sleeve to clamp the pin sleeve and adjust the radial position of the grouting sleeve through the pin sleeve.

[0013] According to the above technical solution, a cylinder four is fixedly connected to the inner wall of the slide table two. The output end of the cylinder four is fixedly connected to the outer wall of the guide sleeve. The cylinder four is used to drive the guide sleeve to slide on the inner wall of the support plate two, and to drive the adjusting block to adjust the axial position of the pin sleeve in the grouting sleeve through the guide sleeve.

[0014] According to the above technical solution, the bottom of the second support plate is slidably connected to a support block via a slider. The outer wall of the support block is fixedly connected to the outer wall of the first positioning grabber through the sliding groove. The support block supports and drives the second support plate to be adjusted synchronously through the first positioning grabber. The adjustment block is equipped with an infrared sensor to sense the position of the pin sleeve.

[0015] According to the above technical solution, a baffle is fixedly connected to the outer wall of the slide table one away from the positioning grabber two, and a spring is fixedly connected to the outer wall of the slide table one near the baffle. The other end of the spring is in contact with the transmission wheel set in the material channel. The spring is used to support the slide table one. When the slide table two is driven by the cylinder two to move away from the grouting sleeve, the outer wall of the slide table two contacts the outer wall of the baffle, so that the slide table two is limited by the baffle, and drives the spring of the slide table one to move synchronously with the slide table two. When the slide table two is driven by the cylinder two to move towards the grouting sleeve, the outer wall of the slide table two contacts the stepped surface of the slide table one, supporting the slide table one, so that the slide table one drives the positioning grabber one and the positioning grabber two to clamp the grouting sleeve.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1, please refer to Figures 1-6The present invention provides a technical solution: a grouting sleeve pin welding conveying positioning and fixing device, including a material channel 100 and a welding gun 103, a support plate 105 fixedly connected to the bottom of the material channel 100, and a positioning mechanism 200 provided on the surface of the support plate 105.

[0032] In the operation of the grouting sleeve pin welding conveying positioning and fixing device, the grouting sleeve is cylindrical, and the pin is prone to radial displacement during the conveying process, which affects the welding accuracy of the grouting sleeve and the sealing performance during use. Therefore, a positioning mechanism 200 is set to position and support the grouting sleeve, and adaptively adjusts according to the diameter of the grouting sleeve, increasing the adaptability of the grouting sleeve pin welding conveying positioning and fixing device to welding different models of grouting sleeves. At the same time, the positioning mechanism 200 supports the grouting sleeve during the positioning process, preventing the grouting sleeve from contacting the equipment and causing scratches during the positioning adjustment process, and increasing the stability of the grouting sleeve pin positioning process.

[0033] The positioning mechanism 200 includes a slide table 201, a positioning gripper 206 fixedly connected to the inner wall of the slide table 201, and a positioning gripper 203 slidably connected to the inner wall of the slide table 201. The inner walls of both the positioning gripper 203 and the positioning gripper 206 are arc-shaped surfaces used to fit the grouting sleeve and position it. A sliding groove 204 is formed on the inner wall of the slide table 201. The inner wall of the sliding groove 204 is slidably connected to the outer wall of the positioning gripper 203 via a slider. The sliding groove 204 is used to guide and limit the positioning gripper 203. An elastic push rod 20 is fixedly connected to the top of the slide table 201. 5. The output end of the elastic push rod 205 passes through the top of the slide table 201 and is fixedly connected to the top of the positioning grabber 203. The bottom of the slide table 201 is slidably connected to the surface of the support plate 105 via a slide rail. The elastic push rod 205 is used to support the positioning grabber 203 and drive it to reset. The inner wall of the positioning grabber 206 is rotatably connected to the guide wheel 208 via a rotating shaft. The guide wheel 208 is supported by the positioning grabber 206 and contacts the outer wall of the grouting sleeve, and rolls along the outer wall of the grouting sleeve by friction. The guide wheel 208 is used to support the grouting sleeve and prevent it from rolling. Positioning gripper 206 scratches the outer wall of the grouting sleeve. A guide plate 202 is fixedly connected to the outer wall of slide table 201. The guide plate 202 guides the grouting sleeve during transport. A guide wheel 209 is rotatably connected to the outer wall of positioning gripper 203 via a rotating shaft. The guide wheel 209 contacts the outer wall of the grouting sleeve through the support of positioning gripper 203 and rolls along the outer wall of the grouting sleeve due to friction. The guide wheel 209, by contacting the outer wall of the grouting sleeve and adjusting the diameter of the grouting sleeve, drives positioning gripper 203 to slide on the inner wall of slide table 201 for adjustment. The inner wall of the positioning gripper 203 is in contact with the outer wall of the grouting sleeve. The slide table 201 is equipped with an infrared sensor at one end near the grouting sleeve to sense the position of the grouting sleeve. The material channel 100 conveys the grouting sleeve by a transmission wheel driven by a servo motor. A slide 101 is fixedly connected to the outer wall of the material channel 100. A cylinder 102 is fixedly connected to the top of the slide 101. The output end of the cylinder 102 is fixedly connected to the top of the welding gun 103. The slide 101 is driven by a servo motor to adjust the welding gun 103 on the X-axis. The cylinder 102 is used to drive the welding gun 103 to adjust the Z-axis.

[0034] When the grouting sleeve pin welding conveying and positioning device is put into use, the grouting sleeve with the pin spot welded and positioned is placed on the surface of the material channel 100. The servo motor on the outer wall of the material channel 100 drives the conveying wheel to transport the grouting sleeve to the slide table 201. The infrared sensor on the outer wall of the slide table 201 senses the position of the grouting sleeve. When the grouting sleeve moves to the corresponding welding position, the servo motor on the outer wall of the material channel 100 stops, and the cylinder 104 is activated. The second movable slide table 301 slides towards the grouting sleeve. The first slide table 201, supported by the spring 211, slides towards the grouting sleeve on the surface of the first support plate 105, causing the inner wall of the second positioning grabber 206 to contact the outer wall of the grouting sleeve, thus positioning the grouting sleeve. During the contact between the second positioning grabber 206 and the outer wall of the grouting sleeve, the first guide wheel 208 contacts the outer wall of the grouting sleeve and rolls along the outer wall of the grouting sleeve, preventing the second positioning grabber 206 from scratching the grouting sleeve during the positioning process. After the inner wall of the grouting sleeve contacts the outer wall of the grouting sleeve, the inner wall of the grouting sleeve 206 contacts the outer wall of the grouting sleeve simultaneously. At the same time, the guide wheel 209 contacts the outer wall of the grouting sleeve and rolls along it. The supporting force of the guide wheel 209 on the outer wall of the grouting sleeve causes the grouting sleeve 203 to press against the elastic push rod 205, which slides along the inner wall of the slide table 201 to adjust its position. This allows the grouting sleeve 203 to be adjusted according to its diameter and to engage with the grouting sleeve. After the outer wall of the sleeve is fitted, the position of the pin sleeve is adjusted by the clamping mechanism 300, and the grouting sleeve is axially adjusted. The slide table 201 supports the slide table 201, so that the positioning grabber 206 and the positioning grabber 203 cooperate to clamp the grouting sleeve. Then, the servo motor set on the outer wall of the slide 101 is started to adjust the welding gun 103 in the X-axis. The cylinder 102 is started to drive the welding gun 103 to descend in the Z-axis direction to weld the pin sleeve of the grouting sleeve.

[0035] Example 2, based on Example 1, please refer to... Figures 7-8 The present invention provides a technical solution: a cylinder 104 is fixedly connected to the outer wall of the material channel 100, and a clamping mechanism 300 is provided on the inner wall of the slide table 201.

[0036] In the operation of the grouting sleeve pin welding conveying positioning and fixing device, the grouting sleeve is cylindrical, and the pin is prone to radial displacement during conveying, which affects the welding accuracy of the grouting sleeve and its sealing performance during use. Therefore, a clamping mechanism 300 is set to position the pin and cooperate with the positioning mechanism 200 to radially adjust the position of the grouting sleeve through the pin, preventing radial displacement of the grouting sleeve during clamping, which would affect the welding accuracy of the grouting sleeve and increase the stability of the grouting sleeve welding. At the same time, the clamping mechanism 300 and the positioning mechanism 200 cooperate to clamp the grouting sleeve after positioning, preventing radial displacement of the grouting sleeve due to heat during welding, and increasing the stability of the grouting sleeve welding.

[0037] The clamping mechanism 300 includes a second slide table 301. The outer wall of the second slide table 301 is fixedly connected to the output end of a second cylinder 104. The second cylinder 104 is used to drive the second slide table 301 to slide on the inner wall of the first slide table 201. A pressure block 302 is fixedly connected to the outer wall of the second slide table 301 near the first positioning gripper 203. The outer wall of the pressure block 302 slides along the guide groove 207. The pressure block 302 is made of heat-resistant rubber and is used to contact and clamp the outer wall of the grouting sleeve through the support of the second slide table 301. A second support plate 303 is slidably connected to the inner wall of the second slide table 301. The second support plate 303 slides up and down along the inner wall of the second slide table 301. A second sliding groove 309 is opened on the outer wall of the second support plate 303. A guide sleeve 304 is slidably connected to the inner wall of the support plate 303. An adjusting block 307 is slidably connected to the inner wall of the guide sleeve 304. A cylinder 305 is fixedly connected to the outer wall of the support plate 2 303. The output end of the cylinder 305 passes through the sliding groove 2 309 and is fixedly connected to the end of the adjusting block 307 near the cylinder 305. The adjusting block 307 is supported by the cylinder 305 and contacts the outer wall of the grouting sleeve pin sleeve to clamp the pin sleeve and adjust the radial position of the grouting sleeve through the pin sleeve. A cylinder 4 306 is fixedly connected to the inner wall of the slide plate 2 301. The output end of the cylinder 4 306 is fixedly connected to the outer wall of the guide sleeve 304. The cylinder 4 306 is used to drive the guide sleeve 304 to slide on the inner wall of the support plate 2 303. The guide sleeve 304 drives the adjusting block 307 to adjust the axial position of the pin sleeve in the grouting sleeve. The bottom of the second support plate 303 is slidably connected to the support block 308 via a slider. The outer wall of the support block 308 passes through the sliding groove 204 and is fixedly connected to the outer wall of the positioning grab 203. The support block 308 supports and drives the second support plate 303 to adjust synchronously through the positioning grab 203. The adjusting block 307 is equipped with an infrared sensor to sense the position of the pin sleeve. A baffle 210 is fixedly connected to the outer wall of the slide table 201 away from the positioning grab 206. A spring 211 is fixedly connected to the outer wall of the slide table 201 near the baffle 210. The other end of the spring 211 When the transmission wheel of the material channel 100 is in contact with the spring 211, the spring 211 is used to support the slide table 201. When the slide table 301 is driven by the cylinder 2104 to move away from the grouting sleeve, the outer wall of the slide table 301 contacts the outer wall of the baffle 210, so that the slide table 301 is limited by the baffle 210, which drives the slide table 201 to compress the spring 211 and move synchronously with the slide table 301. When the slide table 301 is driven by the cylinder 2104 to move closer to the grouting sleeve, the outer wall of the slide table 301 contacts the step surface of the slide table 201, supporting the slide table 201, so that the slide table 201 drives the positioning grabber 1 203 and the positioning grabber 206 to clamp the grouting sleeve.

[0038] After the grouting sleeve is positioned by the infrared sensor installed on the outer wall of the slide table 201, the cylinder 104 drives the slide table 301 to move towards the grouting sleeve. This releases the limit on the slide table 201 by the baffle 210, allowing the slide table 201 to slide on the surface of the support plate 105 supported by the spring 211. This, in turn, causes the positioning grabbers 203 and 206 to position the grouting sleeve. Simultaneously, the positioning grabber 203 rolls along the outer wall of the grouting sleeve via the guide wheel 209, moving the positioning grabber 203 on the slide table 201. When the inner wall slides for position adjustment, positioning grabber 203 drives support block 308 to support support plate 203, causing support plate 203 to drive adjusting block 307 for height adjustment via guide sleeve 304, so that adjusting block 307 matches the height position of pin sleeve. After the grouting sleeve is positioned, slide table 201 is supported by spring 211, and slide table 201 does not contact the stepped surface of slide table 201 to support slide table 201. Cylinder 4 306 drives guide sleeve 304 to slide on the inner wall of support plate 203, and adjusting block 307... 07. After the internal infrared sensor locates the pin sleeve and aligns it with the pin sleeve position, cylinder 305 drives adjusting block 307 to slide along the inner wall of guide sleeve 304 towards the pin sleeve, positioning the adjusting block 307. This allows adjusting block 307 to adjust the radial position of the grouting sleeve via the pin sleeve, ensuring the pin sleeve remains vertical during welding. After the radial position of the grouting sleeve is adjusted, cylinder 305 and cylinder 104 work together, with cylinder 104 driving slide 2 301 to continue sliding towards slide 1 201, causing the pressure block... 302 slides along the guide groove 207 towards the grouting sleeve to clamp the grouting sleeve. At the same time, the bottom of the second slide table 301 contacts the step surface of the first slide table 201 to support the first slide table 201. The first slide table 201 clamps the outer wall of the grouting sleeve through the cooperation of the first positioning grabber 203 and the second positioning grabber 206. While the pressure block 302 is clamping the grouting sleeve, the third cylinder 305 retracts while the adjusting block 307 is supporting the pin sleeve, to prevent the grouting sleeve from undergoing radial displacement during clamping, which would affect the welding accuracy of the grouting sleeve.
