Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of clamp control for welding connection of aviation pipeline conduit and pipeline parts, and particularly relates to a positioning and detecting device for conduit welding clamp unit and a positioning method thereof. BACKGROUND

[0002] After the conduit is processed and shaped, the sections of the conduit and the end head need to be combined and connected together. In most cases, welding connection is adopted. Especially in the case that the end head is provided with a flange plate and the pipeline has branches, the relative positions between the conduits and between the conduit and the pipeline part need to be positioned. At this time, a welding special clamp tool for a certain type of conduit is often designed according to the conduit, and the function of the tool is to combine and fix the parts of the pipeline conduit according to the shape and position of the conduit, and then stably weld the conduit section by section. The welding tool effectively positions the position and direction of the conduit, and meets the consistency requirement. The welding tool for the conduit is generally composed of a clamp body, a positioner, a conduit clamp, a conduit bracket and the like, and the structure of each unit component is shown in Figure 1 .

[0003] The special clamp for conduit welding is often delivered in the form of a unit scattered part, and the unit scattered parts need to be positioned and combined and welded into a unit component. Whether the positioning between the unit scattered parts is accurate and reliable needs to be detected and controlled by a special tool. After the unit scattered parts are combined and welded, the clamp body is assembled into a whole clamp through the positioning part and the connecting part. Whether the manufacturing precision of the conduit welding clamp affects the overall forming quality of the conduit welding, and therefore the quality control of the conduit welding clamp is not only the precision problem of the clamp itself, but also the reliable guarantee of the quality of the conduit welding. The device is a control device for the space positioning and welding of the unit of the conduit welding clamp and the detection of key parameters such as the inclination angle of the unit after welding, the height of the center hole to the bottom plate and the like. The structure of the unit combination is shown in Figure 2 . SUMMARY

[0004] In order to solve the problems of difficult positioning of the unit of the conduit welding clamp, position and size precision and the like, the application provides a device for positioning and detecting the unit of the conduit welding clamp. The data deviation of the inclination angle of the shaft sleeve of each unit of the clamp, the height position of the center hole, the length of the support rod and the position of the bottom plate is detected and controlled at one time, and the problems can be quickly found and solved. The device can be used as the precision control basis for the positioning and welding of the unit combination, and can also be used for data compliance detection after the unit welding.

[0005] The technical solution of the application is a device for positioning and detecting the unit of the conduit welding clamp, which comprises a fixing mechanism, a positioning and detecting mechanism and an adjusting mechanism.

[0006] The fixing mechanism comprises a base, a base body, and a base upper block. The base is a support, protection and fixing platform of the whole device. The base body is arranged on the base and fixedly connected. The base upper block is arranged on the base body and fixedly connected. The thick base guarantees the rigidity and strength of the whole device.

[0007] The positioning detection mechanism is connected with the fixing mechanism. The positioning detection mechanism comprises a sliding groove, a sliding ruler, a positioning mechanism, and a rotating disc. The positioning mechanism comprises a positioning shaft pin, a positioning pin two, a positioning shaft sleeve, a locking nut, and a positioning pad block. The adjusting mechanism comprises an adjusting rod and a V-shaped block.

[0008] The base body and the sliding groove cooperate to form a moving pair. The base body is designed with double cross-shaped notches for placing the sliding groove and matching the outer dimensions of the sliding groove, so that the sliding groove can slide forward and backward and be fixed left and right. The base body is symmetrically designed with internal threaded holes on the front and rear sides for installing the adjusting rods. The rod part of the adjusting rod is designed with external threads. The two threaded rotating parts are used to adjust the position of the sliding groove in the base body. The position of the sliding groove relative to the base body is limited and does not need to be adjusted. One adjusting rod is rotated to push, and the other adjusting rod is rotated to loosen, so as to fix the position of the sliding groove in the base body after adjusting the position of the sliding groove in the base body. The sliding ruler and the sliding groove cooperate to form a moving pair. The sliding groove is designed with a sliding groove. The sliding ruler is arranged in the groove of the sliding groove and slides in the groove of the sliding groove through the sliding fitting surface. The sliding ruler is provided with a straight line scale mark for recording the offset distance of the sliding ruler. Of course, a tool with a length measuring function such as a caliper can also be used to measure the displacement distance of the sliding ruler end through the reference surface of the sliding groove and the sliding ruler.

[0009] The sliding ruler is provided with a positioning plate at one end close to the rotating disc. The positioning plate is provided with a circular hole at the same position as the unit bottom plate. The positioning pin is passed through the positioning plate and the circular hole of the sliding ruler to connect the unit bottom plate. The V-shaped block is freely slidably arranged in the groove of the sliding groove close to the rotating disc. The length and quantity of the V-shaped block can be adjusted according to the length and position of the support rod. The V-shaped surface of the V-shaped block is used to position the unit support rod. The U-shaped groove designed on the rotating disc is used to clamp the positioning shaft pin and the positioning shaft sleeve. The positioning shaft pin and the positioning shaft sleeve are combined to clamp the two end faces of the unit shaft sleeve, and the locking nut is threadedly connected with the positioning shaft pin to lock the two ends of the unit shaft sleeve. The positioning pin is sequentially passed through the center hole of the pipe clamp unit shaft sleeve, the positioning shaft pin, and the through hole on the positioning pad block to limit the rotational freedom of the unit shaft sleeve in the axial direction, so as to finally position and fix the unit shaft sleeve.

[0010] The boss on the rotating disc and the counterbore on the base body form a rotating pair, which can rotate in the counterbore of the base body. The rotating disc is provided with a division line mark, which can directly show the angle of rotation. Of course, an angle ruler or other tools with angle measuring function can also be used to measure the angle of rotation through the measuring surface formed by the base body and the rotating disc.

[0011] The upper block of the base is fixedly connected to the base body and serves as a fixed reference to cooperate with the turntable to complete measurement and detection of the rotation angle. After the rotation angle of the turntable is determined, the upper block is locked by a pressing plate screw, a pressing plate and a locking plate.

[0012] The device can be used to measure and determine the key parameters such as the rotation angle of the turntable and the displacement of the slide ruler, and then to position, clamp and weld the unit assembly after welding.

[0013] Further, the base body and the base are fixedly connected by a screw C.

[0014] Further, the upper block of the base and the base body are fixedly connected by a cylindrical pin and a screw B.

[0015] Further, the slide ruler and the slide groove are connected and locked by a slide ruler pressing strip and a screw A at the end away from the turntable.

[0016] Further, the length and number of the V-shaped blocks can be determined according to the length and position of the support rod of the catheter clamp unit.

[0017] Further, the length of the base is greater than the length of the slide ruler, which can effectively protect the slide ruler from being scratched or damaged during transportation and movement.

[0018] On the other hand, a positioning method using the above-mentioned device for positioning and detecting the catheter welding clamp unit is also provided, which includes the following steps: the combination of the positioning shaft pin and the positioning shaft sleeve clamps the two end faces of the catheter clamp unit shaft sleeve into the U-shaped groove and is positioned by the positioning pin II, thereby realizing the planar positioning control of the unit shaft sleeve, and the center hole of the unit is positioned by inserting the positioning pin into the center hole of the turntable; according to the required angle of the clamp unit shaft sleeve and the support rod to be welded, the turntable is rotated to the required angle, and then the upper block of the base is locked by the pressing plate and the pressing plate screw, thereby realizing the pitch and roll angle positioning detection of the unit shaft sleeve; the adjusting rods on both sides of the base body are rotated to the required position of the unit support rod and the unit bottom plate, and then the adjusting rods are pushed and locked; the slide ruler is moved to the required height of the unit support rod and the unit bottom plate, and then the slide ruler pressing strip and the screw A are connected and locked, thereby realizing the length positioning of the unit support rod, and the V-shaped surface of the V-shaped block positions the unit support rod; finally, the cooperation of the catheter welding clamp unit in the device is used to realize the stable positioning of the unit.

[0019] The unit shaft sleeve plane is positioned and controlled in the two semicircular grooves of the provided rotary disc; the unit center hole position is aligned with the center hole positioning pin inserted into the rotary disc; the unit support rod height and the height of the center hole to the unit bottom plate are determined by the extension amount of the slide ruler; the unit support rod and the unit shaft sleeve are welded on both sides of the long and short, which are positioned by the bottom plate plane of the slide ruler, the position of the unit bottom plate is determined by the positioning plate aligned with the slide ruler, and adjusted left and right by the provided adjusting rod, the unit support rod is positioned by the V-shaped block surface, and the offset amount is determined by the extension amount of the slide ruler; the unit shaft sleeve pitch angle is adjusted by adjusting the rotary disc, and the angle can be detected.

[0020] After positioning, on the one hand, each unit is positioned and welded in combination according to the angle, height and plane requirements by using the matching relationship of the welding fixture units, and the conformity is detected after welding. On the other hand, the welded positioning units can be assembled on the plate body according to their respective positions by using positioning members such as pins and connecting members such as screws, so as to ensure that the fixture meets the requirements of positioning and inspection.

[0021] The beneficial effects of the present application are as follows:

[0022] The device not only realizes the precision control of the fixture units before welding, but also increases the quality control of the fixture units after welding. The closed-loop control before and after realizes the accurate control of the welded fixture units, and can be widely used for positioning and welding of the catheter welding fixture unit combination and conformity detection control after the unit assembly is welded. The innovative design not only solves the problem of positioning of the welding fixture, but also provides a solution for detection of the fixture combined unit. BRIEF DESCRIPTION OF DRAWINGS

The positioning mechanism comprises a positioning shaft pin 34, a positioning pin-two 35, a positioning shaft sleeve 36, a locking nut 37 and a positioning pad 38. The positioning shaft pin 34 passes through the catheter clamp unit shaft sleeve 14, the positioning shaft sleeve 36 and the locking nut 37 in sequence. The positioning shaft pin 34 and the positioning shaft sleeve 36 are combined to clamp the two end faces of the catheter clamp unit shaft sleeve 14. The positioning shaft pin 34 and the positioning shaft sleeve 36 are disposed in the U-shaped groove 331 and connected with the external thread 342 of the positioning shaft pin 34 through the locking nut 37 to lock the two ends of the catheter clamp unit shaft sleeve 14.

One of the adjusting rods 41 is rotated to push, and the other adjusting rod 41 is rotated to loosen, so as to move and fix the position of the adjusting sliding groove 31 in the base body 22. The V-shaped blocks 42 are placed in the notches of the sliding grooves 31 close to the rotating disc 33 and are freely slid to the required positions. The V-shaped surfaces 421 are used for positioning the support rods 12 of the catheter clamp unit.

[0049] The base upper block 23 is designed with a zero position scale line aligned with the center of the rotating disc 33. The base upper block 23 serves as a fixed reference to complete the measurement and detection of the rotating angle of the rotating disc. After the rotating angle of the rotating disc 33 is determined, the pressing plate screw 43 is used to connect and lock the base upper block 23 through the inner threaded hole five 441 on the pressing plate 44.

The length of the base 21 is greater than the length of the sliding ruler 32, which can effectively protect the sliding ruler 32 from being scratched and damaged during transportation and movement.

[0050] The positioning shaft pin 34 and the positioning shaft sleeve 36 are combined to clamp the two end faces of the catheter clamp unit shaft sleeve 14 in the U-shaped groove 331 and are positioned through the positioning pin two 35, so as to realize the plane positioning control of the unit shaft sleeve 14. The center hole 15 of the unit shaft sleeve is aligned with the center hole two 333 of the rotating disc 33 and is inserted into the positioning pin two 35 for positioning. According to the required unit shaft sleeve pitch angle a of the clamp unit shaft sleeve 14 to be welded and the unit support rod 12, the rotating disc 33 is rotated to the required angle, and the pressing plate 44 and the pressing plate screw 43 are used to connect and lock the base upper block 23, so as to realize the positioning and detection of the unit shaft sleeve pitch angle a. The adjusting rods 41 on both sides of the base body 22 are rotated to the required position of the unit support rod 12 and the unit bottom plate 11, and then the adjusting rods 41 are used to push and lock. The sliding ruler 32 is moved to the required center hole of the unit support rod 12 and the unit bottom plate 11 to the height h of the unit bottom plate, and then the sliding ruler pressing strip 45 and the screw A 46 are used to connect and lock, so as to realize the length positioning of the unit support rod 12.
