[0016] A positioning operation method in a high temperature sensor welding process comprises the following steps:

[0017] S1: Positioning and clamping: Place the sensor component to be welded on the top of the second box body, control the motor three to start, drive the connecting shaft two to rotate, drive the connecting shaft one to rotate under the action of the turbine two, drive the positioning plate two to rotate, drive the sleeve shaft one to move upward inside the mounting sleeve, and under the action of the thread, the threaded sleeves on the outer surfaces of the two threaded rods two can move toward each other, drive the moving plate to move toward each other inside the positioning groove, and the two mounting plates and the clamping plate move toward each other at the top of the second box body until the sensor component is clamped between the two clamping plates, completing the stable clamping and positioning of the sensor component;

[0018] S2: Parts pre-welding: The electric telescopic rod is controlled to shrink by touching the switch, driving the movable block to move inside the installation slot, driving the sleeve shaft 2, the pulley 1 and the sanding belt to gradually approach the outer surface of the sensor component, until the sanding belt fits the outer surface of the sensor component, and the sensor component can be driven to rotate on the top surface of the box 2 by the motor 2 through the box 2.

During this period, the sensor component can be cleaned synchronously to obtain a perfect sensor component after welding without the need for subsequent processing;

[0022] S6: Parts welding is completed: The two mounting plates and the clamping plate are driven to rotate in opposite directions by the reverse rotation of motor 3, so that the sensor component loses its clamping, thereby removing the welded sensor component and replacing it with the next sensor component that needs to be welded.

[0023] The present invention provides a positioning tool and an operating method for high temperature sensor welding, and its beneficial effects include:

[0024] 1. By setting up a transmission component and a positioning component, the sensor component to be welded is placed on the top of the second box body, and the motor three is controlled to start, driving the connecting shaft two to rotate. Under the action of the turbine two, the connecting shaft one is driven to rotate, driving the positioning plate two to rotate, and driving the sleeve shaft one to move upward inside the mounting sleeve. Under the action of the thread, the threaded sleeves on the outer surfaces of the two threaded rods two can be driven to move toward each other, driving the moving plate to move toward each other inside the positioning groove, and the two mounting plates and the clamping plate move toward each other at the top of the second box body until the sensor component is clamped between the two clamping plates, completing the stable clamping and positioning of the sensor component, thereby achieving the purpose of being able to stably position and clamp the sensor component.

[0025] 2. By setting up a pre-welding component, the electric telescopic rod is controlled to retract by touching the switch, which drives the movable block to move inside the installation groove, drives the sleeve shaft 2, the pulley 1 and the sanding belt to gradually approach the outer surface of the sensor component, until the sanding belt fits the outer surface of the sensor component, and the sensor component can be driven to rotate on the top surface of the box body 2 under the drive of the motor 2. When the sanding belt contacts the outer surface of the sensor component, the temperature of the sensor component gradually rises, which plays a preheating role, so that the sensor component will not be directly welded when the temperature is too low, thereby achieving the purpose of good preheating and avoiding the problem of bubbles that are prone to appear in the subsequent welding process due to large temperature differences, thereby affecting the welding quality.

[0026] 3. By setting up the oil removal component, when the electric telescopic rod drives the movable block to move toward the direction close to the sensor component, it drives the L-shaped frame, the water distribution frame and the C-shaped frame to synchronously approach the sensor component, and the liquid pusher plate squeezes the capsule, and squeezes the mixed liquid inside the capsule into the inside of the liquid outlet pipe, and sprays it on the surface of the sensor component through the nozzle. The mixed liquid sprayed on the outer surface of the sensor component can effectively remove the oil stains and other attachments on the outer surface of the sensor component, so that the sensor component can be welded in a clean state, thereby further improving the welding effect.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0040] The positioning and clamping mechanism includes a transmission component 11, a top plate 12 and a positioning component 13. The transmission component 11 includes a box body 111, which is fixedly installed on the top surface of the placement plate 10. The top plate 12 is fixedly installed on the top surface of the box body 111. The positioning component 13 includes a box body 131, which is rotatably installed on the top surface of the top plate 12. A pre-welding component 15 and an oil removal component 16 are arranged above the box body 111.

[0041] The interior of the box body 111 is fixedly installed with a motor 2 112 and a motor 3 113. The inner wall of the box body 111 is fixedly installed with a positioning plate 115. The interior of the positioning plate 115 is rotatably sleeved with a rotating shaft 116. The bottom end of the rotating shaft 116 is fixedly connected to a gear 2 117. The output end of the motor 2 112 is fixedly connected to a gear 114. The gear 114 and the gear 2 117 are meshed with each other. The output end of the motor 3 113 is fixedly connected to a connecting shaft 2 1122. The connecting shaft 2 1122 is fixedly connected to the output end of the motor 3 113. A vortex groove 1123 is provided on the outer surface, and two positioning plates 119 are fixedly installed on the inner wall of the box body 111. A connecting shaft 1120 is rotatably installed inside the two positioning plates 119. The outer surfaces of the connecting shaft 1120 are respectively sleeved with turbine 1121 and turbine 2 1124, and the turbine 2 1124 and the connecting shaft 2 1122 are meshed with each other through the vortex groove 1123. The outer surface of the rotating shaft 116 is sleeved with a worm sleeve 118, and the turbine 1121 and the worm sleeve 118 are meshed with each other.

[0042] A positioning shaft 132 is rotatably installed inside the second box body 131, and a turbine three 133 is fixedly sleeved on the outer surface of the positioning shaft 132. The turbine three 133 is meshed with the worm sleeve 118, and threaded rods 134 are fixedly installed on both ends of the positioning shaft 132. A threaded sleeve 135 is threadedly sleeved on the outer surface of the threaded rod 134, and a moving plate 136 is fixedly installed on the top surface of the threaded sleeve 135. A positioning groove 139 is opened inside the second box body 131, and the moving plate 136 is movably clamped in the inside of the positioning groove 139. The top of the moving plate 136 is fixedly connected to a mounting plate 137, and a clamping plate 138 is fixedly installed on one end of the mounting plate 137. The sensor component 14 is clamped between the two clamping plates 138.

[0043] During operation, in the process of welding the sensor component 14, the sensor component 14 to be welded is first placed on the top of the second box body 131, and then the third motor 113 is controlled to start. During the start-up of the third motor 113, the second connecting shaft 1122 can be driven to rotate. Since the second connecting shaft 1122 and the second turbine 1124 are meshed with each other through the vortex groove 1123, when the second connecting shaft 1122 rotates, the first connecting shaft 1120 can be driven to rotate under the action of the second turbine 1124, thereby driving the second positioning plate 119 to rotate. When the second positioning plate 119 rotates, the first sleeve shaft 1162 can be driven to move upward inside the mounting sleeve 1161. During the movement, the worm sleeve 118 and the turbine 1124 are engaged with each other through the vortex groove 1123. The mutual meshing of the three 133 can drive the turbine three 133 to rotate, thereby driving the threaded rod two 134 located on both sides of the positioning shaft 132 to rotate. During the rotation process, due to the threaded sleeve 135 with a thread sleeve on its outer surface, the threaded sleeve 135 on the outer surface of the two threaded rods 134 can be driven to move toward each other under the action of the thread, thereby driving the movable plate 136 to move toward each other inside the positioning groove 139. Therefore, the two mounting plates 137 and the clamping plate 138 can move toward each other at the top of the box body 131 until the sensor component 14 is clamped between the two clamping plates 138, thereby completing the stable clamping and positioning of the sensor component 14, thereby achieving the purpose of being able to stably position and clamp the sensor component 14.

[0044] The rotating shaft 116 includes a mounting sleeve 1161 and a sleeve shaft 1162. The sleeve shaft 1162 is movably inserted in the interior of the mounting sleeve 1161. The gear 2 117 is fixedly installed on the bottom surface of the mounting sleeve 1161. A slot 1163 is provided in the interior of the mounting sleeve 1161. An insert plate 1164 is fixedly installed on the outer surface of the sleeve shaft 1162. The insert plate 1164 is inserted in the interior of the slot 1163. By movably inserting the sleeve shaft 1162 in the interior of the mounting sleeve 1161, the sleeve shaft 1162 can be moved in the interior of the mounting sleeve 1161 during the start-up of the motor 3 113, and the rotating shaft 116 can be driven to rotate under the action of the gear 114 and the gear 2 117 during the rotation of the motor 2 112.

[0045] Among them, after the sensor component 14 is stably clamped, the sleeve shaft 1162 is inserted into the inside of the plug-in hole on the bottom surface of the inner bottom of the box body 131. At this time, by controlling the motor 112 to start, the gear 114 can be driven to rotate. Since the gear 114 and the gear 2 117 are meshed with each other, the rotating shaft 116 can be driven to rotate. After clamping, one end of the sleeve shaft 1162 is inserted into the inside of the plug-in hole, so that the box body 131 can be driven to rotate on the top of the top plate 12, so that the sensor component 14 can be rotationally welded during the welding process.

[0046] The pre-welding assembly 15 includes a side plate 151, the number of which is two. The two side plates 151 are symmetrically mounted on the outer surface of the top plate 12. A mounting groove 152 is provided inside the side plate 151. An electric telescopic rod 153 is installed inside the mounting groove 152. A movable block 154 is movably connected to the inner surface of the mounting groove 152. One end of the electric telescopic rod 153 is fixedly connected to a side surface of the movable block 154. A sleeve shaft 155 is rotatably mounted inside the movable block 154. A pulley 156 is fixedly mounted on the top of the sleeve shaft 155. A sanding belt 157 is sleeved inside the two pulleys 156. An extension plate 159 is fixedly mounted on one side surface of the main frame 1. The inner surface of the extension plate 159 is fixedly mounted on the inner surface of the extension plate 159. A mounting shaft 1510 is rotatably installed on the part, and a pulley 1511 is fixedly installed on the outer surface of the mounting shaft 1510 and the outer surface of the output end of the motor 112, and a transmission belt 1512 is sleeved between the two pulleys 1511. A gear 1513 is fixedly installed on the top of the mounting shaft 1510, and a gear 3 158 is fixedly installed on the bottom end of one sleeve shaft 155. A mounting seat 1514 is fixedly installed on the top surface of the box body 131, and a touch switch 1515 is fixedly installed on one side surface of the mounting seat 1514. A temperature sensor 1516 is fixedly installed on the top surface of the mounting seat 1514, and the temperature sensor 1516, the mounting seat 1514 and the electric telescopic rod 153 are electrically connected.

[0047] During operation, when the two clamping plates 138 clamp the sensor component 14, one of the mounting plates 137 can squeeze the touch switch 1515, that is, it can touch and turn on the touch switch 1515, and then control the electric telescopic rod 153 to retract through the touch switch 1515. During the retraction process, the movable block 154 can be driven to move inside the mounting groove 152. During the movement process, the sleeve shaft 155, the pulley 156 and the sanding belt 157 can be driven to gradually approach the outer surface of the sensor component 14 until the sanding belt 157 fits the outer surface of the sensor component 14. During this period, the motor 157 is moved by the box body 131. Driven by the second 112, the sensor component 14 can be driven to rotate on the top surface of the box body 131. After the sanding belt 157 contacts the outer surface of the sensor component 14, on the one hand, it can perform a good polishing operation on the sensor component 14 to improve the subsequent welding quality. On the other hand, as the sensor component 14 continues to rotate and is always in contact with the mounting plate 137, the temperature of the sensor component 14 can gradually increase, thereby playing a good preheating role, so that the sensor component 14 will not be directly welded when the temperature is too low, thereby avoiding the problem of bubbles that are prone to appear during the subsequent welding process due to the large temperature difference, thereby affecting the welding quality.

[0048] Moreover, as the electric telescopic rod 153 drives the movable block 154 to move continuously, the gear 3 158 at the bottom end of one of the sleeve shafts 155 can be gradually approached to the gear 4 1513. During this period, the speed of the motor 2 112 can be controlled to keep its speed slow, so as to avoid damage to the gear 3 158 and the gear 4 1513 after they come into contact. When the gear 3 158 and the gear 4 1513 are meshed, the speed of the motor 2 112 can be adjusted to speed up, so as to drive the sleeve shaft 2 155 to rotate, so that the sanding belt 157 can move between the two belts. The wheel 156 rotates internally, and the sensor component 14 is also in a rotating state at this time, so the polishing effect and the preheating effect can be greatly improved, so that the temperature of the sensor component 14 can be quickly increased, thereby meeting the welding requirements. Among them, when the temperature of the sensor component 14 reaches the detection temperature of the temperature sensor 1516, the electric telescopic rod 153 can be controlled by the temperature sensor 1516 to drive the sanding belt 157 away from the sensor component 14. After moving away, the welding head 5 can be driven by controlling the moving head 4 to perform welding operations on the sensor component 14.

[0049] The oil removal assembly 16 includes a storage box 161, which is fixedly mounted on one side surface of the box body 111, a rectangular plate 168 is fixedly mounted on one side surface of the top plate 12, and a mounting box 169 is fixedly mounted on the top surface of the rectangular plate 168. The mounting box 169 has an active cavity 1622, a liquid suction cavity 1623 and an exhaust cavity 1624 formed inside. A capsule 1629 and a liquid pusher plate 1630 are installed inside the liquid suction cavity 1623. The liquid pusher plate 169 is provided with a plurality of movable cavities 1622, a liquid suction cavity 1623 and an exhaust cavity 1624. The movable block 154 is connected to the inside of the liquid suction chamber 1623 and is bonded to one side surface of the capsule 1629, so as to drive the capsule 1629 to absorb the cleaning liquid. The top surface of the installation box 169 is fixedly connected with a liquid outlet pipe 1617, and a one-way valve 1618 is fixedly installed on the outer surface of the liquid outlet pipe 1617. An L-shaped frame 1613 is fixedly installed on one side surface of the movable block 154, and a water distribution frame 1614 is fixedly installed on one end of the L-shaped frame 1613. The water rack 1614 is tilted, and the tilting direction is the direction where the sensor component 14 is located. The water distribution rack 1614 is located above the sensor component 14. A plurality of nozzles 1615 are fixedly connected to the surface of one side of the water distribution rack 1614. The other end of the liquid outlet pipe 1617 is fixedly connected to the outer surface of the water distribution rack 1614. A liquid suction pipe 167 is fixedly connected to the surface of one side of the storage box 161. The other end of the liquid suction pipe 167 is fixedly connected to the surface of one side of the installation box 169. A one-way valve 3 1621 is fixedly installed on the outer surface of the liquid suction pipe 167. A pushing shaft 1631 is fixedly connected between the liquid pushing plate 1630 and the air pushing plate 1627. A sleeve 1632 is fixedly installed on the outer surface of the pushing shaft 1631. A vertical plate 1633 is fixedly installed on the top of the sleeve 1632. A C-shaped frame 1612 is fixedly installed on the top of the vertical plate 1633. One end of the C-shaped frame 1612 is fixedly connected to the L-shaped frame 1613.

[0050] During operation, when the electric telescopic rod 153 drives the movable block 154 to move toward the direction close to the sensor component 14, the L-shaped frame 1613, the water distribution frame 1614 and the C-shaped frame 1612 can be driven to synchronously approach the sensor component 14. When the C-shaped frame 1612 moves, the push shaft 1631 can be driven to move in the movable cavity 1622 toward the liquid suction cavity 1623 under the action of the sleeve frame 1632 and the vertical plate 1633, thereby driving the liquid pushing plate 1630 to squeeze the capsule 1629. The mixed liquid inside 1629 is squeezed into the liquid outlet pipe 1617, and finally enters the water distribution rack 1614, and is sprayed on the surface of the sensor component 14 through the nozzle 1615. The mixed liquid sprayed on the outer surface of the sensor component 14 can effectively remove the oil stains and other attachments on the outer surface of the sensor component 14, and the attachments on the outer surface of the sensor component 14 can also be cleaned by polishing with the sanding belt 157, so that the sensor component 14 can be welded in a clean state, thereby further improving the welding effect.

[0051] An air outlet pipe 1610 is fixedly connected to the top surface of the installation box 169, and the other end of the air outlet pipe 1610 is fixedly connected to a side surface of the water distribution rack 1614. An air inlet pipe 1625 is fixedly connected to a side surface of the installation box 169, and a one-way valve 1626 is fixedly installed on the outer surface of the air inlet pipe 1625. An air push plate 1627 is movably connected to the interior of the exhaust chamber 1624.

[0052] During operation, when the driving shaft 1631 moves toward the interior of the liquid suction chamber 1623, it can drive the air pushing plate 1627 to move toward the direction of the capsule 1629, and suck the outside air into the exhaust chamber 1624 through the air inlet pipe 1625. When the sanding belt 157 moves away from the sensor component 14, it can synchronously drive the driving shaft 1631 to move, that is, drive the driving shaft 1631 to move toward the exhaust chamber 1624, and then drive the air pushing plate 1627 to squeeze the air sucked into the exhaust chamber 1624 into the inside of the one-way valve 1611, and finally enter the inside of the water distribution rack 1614, and then spray it toward the sensor component 14 through the nozzle 1615, so as to dry the sensor component 14. In addition, in the process of the driving shaft 1631 moving toward the interior of the exhaust chamber 1624, the mixed liquid inside the storage box 161 can be re-sucked into the inside of the capsule 1629 through the liquid suction pipe 167, so as to facilitate the cleaning of the next sensor component 14.

[0053] A transmission shaft 1619 is rotatably installed inside the storage box 161, one end of the transmission shaft 1619 extends to the outside of the storage box 161 and is fixedly connected to the bottom end of the mounting shaft 1510, the other end of the transmission shaft 1619 is located inside the storage box 161, and a spiral blade 1620 is fixedly installed on the outer surface.

[0054] During operation, when the installation shaft 1510 rotates, it can drive the transmission shaft 1619 to rotate synchronously. During the rotation, it can drive the spiral blade 1620 to rotate, stirring the mixed liquid inside the storage box 161, thereby preventing the mixed liquid inside the storage box 161 from precipitating. The mixed liquid inside the storage box 161 is alcohol and some degreasing detergent.

[0055] Finally, after the welding is completed, the sanding belt 157 can be driven to approach the sensor component 14 by manually controlling the electric telescopic rod 153 again to grind the welded part after welding. In addition, the sensor component 14 can be cleaned synchronously during this period to obtain a perfect sensor component 14 after welding without the need for subsequent processing, thereby greatly improving the welding production rate of the sensor component 14. Then, the motor three 113 is rotated in the opposite direction to drive the two mounting plates 137 and the clamping plate 138 to rotate in opposite directions, so that the sensor component 14 loses its clamping, thereby removing the welded sensor component 14 and replacing it with the next sensor component 14 that needs to be welded.

[0056] A positioning operation method in a high temperature sensor welding process comprises the following steps:

[0057] S1: Positioning and clamping: Place the sensor component 14 to be welded on the top of the second box body 131, control the third motor 113 to start, drive the second connecting shaft 1122 to rotate, drive the first connecting shaft 1120 to rotate under the action of the second turbine 1124, drive the second positioning plate 119 to rotate, drive the first sleeve 1162 to move upward inside the mounting sleeve 1161, and under the action of the thread, the threaded sleeves 135 on the outer surfaces of the two threaded rods 134 can be driven to move toward each other, drive the moving plate 136 to move toward each other inside the positioning groove 139, and the two mounting plates 137 and the clamping plate 138 to move toward each other at the top of the second box body 131 until the sensor component 14 is clamped between the two clamping plates 138, and the stable clamping and positioning of the sensor component 14 is completed;

[0058] S2: Pre-welding of parts: The electric telescopic rod 153 is controlled to shrink by touching the switch 1515, driving the movable block 154 to move inside the mounting groove 152, driving the sleeve shaft 155, the pulley 156 and the sanding belt 157 to gradually approach the outer surface of the sensor component 14, until the sanding belt 157 fits the outer surface of the sensor component 14, and the sensor component 14 can be driven to rotate on the top surface of the box body 131 through the box body 131 driven by the motor 112. When the sanding belt 157 contacts the outer surface of the sensor component 14, the temperature of the sensor component 14 gradually rises, which plays a preheating role, so that the sensor component 14 will not be directly welded when the temperature is too low;

[0059] S3: Parts processing: When the electric telescopic rod 153 drives the movable block 154 to move toward the direction close to the sensor component 14, the L-shaped frame 1613, the water distribution frame 1614 and the C-shaped frame 1612 are driven to synchronously approach the sensor component 14, and the liquid pusher plate 1630 squeezes the capsule 1629, and squeezes the mixed liquid inside the capsule 1629 into the inside of the liquid outlet pipe 1617, and sprays it on the surface of the sensor component 14 through the nozzle 1615. The mixed liquid sprayed on the outer surface of the sensor component 14 can effectively remove the oil stains and other attachments on the outer surface of the sensor component 14, so that the sensor component 14 can be welded in a clean state;

[0060] S4: Parts welding: After the above steps are completed, the welding head 5 is driven by the moving machine head 4 to approach the rotating sensor component 14 to perform welding operation on the sensor component 14;

[0061] S5: Parts reprocessing: After welding is completed, the electric telescopic rod 153 can be manually controlled to drive the sanding belt 157 close to the sensor component 14 to grind the welded part after welding. During this period, the sensor component 14 can be cleaned synchronously to obtain a perfect sensor component 14 after welding without the need for subsequent processing;

[0062] S6: Parts welding is completed: The motor 3 113 rotates in the reverse direction, driving the two mounting plates 137 and the clamping plates 138 to rotate in opposite directions, so that the sensor component 14 loses its clamping, thereby removing the welded sensor component 14 and replacing it with the next sensor component 14 that needs to be welded.

[0063] It should be noted that the touch switch 1515 and the temperature sensor 1516 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
