Description

Technical Field

[0001] The utility model belongs to the technical field of welding brackets, and particularly relates to a welding tool for a wiring harness installation bracket positioned from inside to outside. Background Art

[0002] In the traditional sense, welding is based on the positioning of the steel pipe end face, and the pins are inserted into the bracket and the steel pipe in sequence from the outside to the inside to achieve the positioning between the bracket and the steel pipe. However, when the diameter of the steel pipe hole on the steel pipe is larger than the diameter of the bracket hole on the bracket, this means that after the pin is inserted from the outside to the inside, the steel pipe will swing left and right, and the prescribed coaxiality requirements of the bracket hole and the steel pipe hole cannot be met, and the positioning is invalid. Therefore, the only method to position it is to insert the pin from the inside to the outside. However, if the traditional mandrel that is contoured to the inner diameter of the steel pipe is used to position the steel pipe axially, the pin will block the steel pipe due to the protruding pin fixed on the mandrel, and the steel pipe will not be able to be put in. Utility Model Content

[0003] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a wiring harness installation bracket welding tool positioned from the inside to the outside, so as to solve the problems mentioned in the background technology.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A wiring harness mounting bracket welding tool positioned from the inside to the outside comprises a base plate, a core shaft is mounted on the base plate, at least two groups of pins are mounted on the core shaft, the pins comprise a bracket end and a steel pipe end, the steel pipe end is mounted on the core shaft, the bracket end is mounted on the steel pipe end, the diameter of the bracket end is smaller than the diameter of the steel pipe end, and the distance from the top end of the bracket end to the bottom end of the core shaft is smaller than the inner diameter of the steel pipe.

[0006] As a preferred technical solution, during welding, there is a gap between the bracket end and the inner wall of the bracket hole on the wire harness mounting bracket, and there is a gap between the steel pipe end and the inner wall of the steel pipe hole on the steel pipe.

[0007] As a preferred technical solution, the core shaft includes an inner shaft and an outer shaft, the inner shaft is installed on the bottom plate, the outer shaft is sleeved outside the inner shaft, and adjustment holes are opened on the inner shaft and the outer shaft.

[0008] As a preferred technical solution, the latch also includes an insertion rod installed at one end of the steel pipe close to the core shaft, and the insertion rod is inserted into the adjustment holes of the inner shaft and the outer shaft.

[0009] As a preferred technical solution, the height from the bottom end of the insertion rod to the top end of the bracket end is greater than the diameter of the outer shaft and smaller than the inner diameter of the steel pipe.

[0010] As an optimal technical solution, a support block is installed on the base plate, the core shaft is installed on the base plate through a mounting plate, the mounting plate is slidably connected to the base plate, an adjusting member is installed on the mounting plate, and a blocking member is installed on the base plate. When the adjusting member and the blocking member are engaged, the mounting plate and the base plate are relatively fixed.

[0011] As a preferred technical solution, the adjusting member includes a rack installed on the side wall of the mounting plate, and the blocking member includes a mounting block installed on the base plate, a clamping block is rotatably installed on the mounting block, an elastic member is installed between the bottom end of the clamping block and the base plate, and the elastic member is in a compressed state. When the top end of the clamping block is engaged with the tooth groove of the rack, the deformation of the elastic member is smaller than the deformation when it is not engaged.

[0012] As a preferred technical solution, the top of the support block is V-shaped.

[0013] The advantages of the utility model are: before fixing the steel pipe, the height of the mounting plate is adjusted according to the diameter of the steel pipe, and the relative distance between the inner axis and the outer periphery is adjusted according to the length from the end of the steel pipe to the steel pipe hole. Since the diameter of the steel pipe hole of the steel pipe is larger than the diameter of the bracket hole on the harness mounting bracket, it is impossible to use the traditional method of fixing, that is, inserting the pin into the harness mounting bracket and the steel pipe from the outside to the inside in sequence, because this method will cause the steel pipe to shake left and right after the pin is inserted, and the bracket hole and the steel pipe hole cannot reach the required coaxiality, and the positioning is invalid. Therefore, the method of inserting the pin from the inside to the outside for positioning is adopted, that is, the steel pipe is sleeved on the outer axis of the core shaft, the steel pipe hole is aligned with the pin, the steel pipe end is clamped with the steel pipe hole, the steel pipe is lowered, so that the steel pipe falls on the support block, the support block prevents the steel pipe from deflecting, and then the bracket hole of the harness mounting bracket is sleeved on the bracket end of the pin, and finally the clamping end of the quick clamp is pressed down to fix the harness mounting bracket, and the welding can be done quickly.

[0014] The height of the mounting plate is adjustable, that is, the relative height between the mandrel and the support block can be adjusted, which is suitable for steel pipes of different diameters. The length of the mandrel is adjustable, which is suitable for welding between steel pipes of different lengths and the wiring harness mounting bracket.

[0025] Preferably, the length direction of the latch pin 6 is perpendicular to the length direction of the core shaft 3, and the fixed end of the latch pin 6 faces upward.

[0026] Preferably, the core shaft 3 includes an inner shaft 31 and an outer shaft 32 . The inner shaft 31 is mounted on the mounting plate 4 through a locking member 7 . The outer shaft 32 is sleeved outside the inner shaft 31 . Adjustment holes are provided on both the inner shaft 31 and the outer shaft 32 .

[0027] Preferably, the pin 6 includes an insert rod 61, a bracket end 62 and a steel pipe end 63, the steel pipe end 63 is located between the insert rod 61 and the bracket end 62, the diameter of the bracket end 62 is smaller than the diameter of the steel pipe end 63, the height of the insert rod 6 is larger than the diameter of the outer shaft 32 and smaller than the inner diameter of the steel pipe 8, the bracket end 62 is clamped with the bracket hole 11, the steel pipe end 63 is clamped with the steel pipe hole 10, the insert rod 61 is inserted into the inner shaft 31 and the outer shaft 32, and the steel pipe end 63 is clamped with the adjustment holes on the inner shaft 31 and the outer shaft 32.

[0028] After removing the latch 6, the relative length of the inner shaft 31 and the outer shaft 32 is adjusted. After adjusting to a suitable position, the insertion rod 61 of the latch 6 is inserted into the inner shaft 31 through the adjustment holes on the inner shaft 31 and the outer shaft 32. The steel pipe end 63 is engaged with the adjustment holes on the inner shaft 31 and the outer shaft 32 so that the inner shaft 31 and the outer shaft 32 are relatively fixed. The length-adjustable mandrel 3 is suitable for steel pipes 8 of more lengths. It is worth noting that there is a gap between the end of the steel pipe 8 and the mounting plate 4 to prevent over-positioning between the steel pipe 8 and the latch 6.

[0029] Preferably, the mounting plate 4 is slidably connected to the base plate 1, an adjusting member 12 is installed on the mounting plate 4, and a blocking member 13 is installed on the base plate 1. The height of the core shaft 3 is adjusted by pulling the mounting plate 4. When adjusted to a suitable height, the blocking member 13 blocks the adjusting member 12, so that the mounting plate 4 is fixed. The adjusting member 12 includes a rack 121, which is mounted on the side wall of the mounting plate 4. The blocking member 13 includes a mounting block 133 on the mounting base plate 1. A clamping block 131 is rotatably mounted on the mounting block 133. The clamping block 131 is Z-shaped, and the top end of the clamping block 131 is clamped with the tooth groove of the rack 121. An elastic member 132 is installed between the bottom end of the clamping block 131 and the base plate 1, and the elastic member 132 is in a compressed state. When it is necessary to adjust the height of the mounting plate 4, the bottom end of the clamping block 131 is pressed down to increase the deformation of the elastic member 132, and the top end of the clamping block 131 is lifted and separated from the rack 121.

Under the elastic force of the elastic member 132, the clamping block 131 rotates, and the top end of the clamping block 131 is pressed down to re-engage with the tooth groove of the rack 121 to limit the mounting plate 4.

[0030] Before fixing the steel pipe 8, the height of the mounting plate 4 is adjusted according to the diameter of the steel pipe 8, and the relative distance between the inner shaft 31 and the outer periphery 32 is adjusted according to the length from the end of the steel pipe 8 to the steel pipe hole 11. Since the diameter of the steel pipe hole 10 of the steel pipe 8 is larger than the diameter of the bracket hole 11 on the wire harness mounting bracket 9, it is impossible to use the traditional method of fixing, that is, inserting the pin 6 into the wire harness mounting bracket 9 and the steel pipe 8 from the outside to the inside in sequence. Because this method will cause the steel pipe to shake left and right after the pin 6 is inserted, the bracket hole 11 and the steel pipe hole 10 cannot achieve the required coaxiality, and the positioning is invalid. Therefore, the method of inserting the pin 6 from the inside to the outside for positioning is adopted, that is: the steel pipe 8 is sleeved on the outer shaft 32 of the core shaft 3, the steel pipe hole 10 is aligned with the pin 6, the steel pipe end 63 is clamped with the steel pipe hole 10, and the steel pipe 8 is lowered so that the steel pipe 8 falls on the support block 5. The support block 5 prevents the steel pipe 8 from deviating, and then the bracket hole 11 of the wire harness mounting bracket 9 is sleeved on the bracket end 62 of the pin 6, and finally the clamping end of the quick clamp 2 is pressed down to fix the wire harness mounting bracket 9, and then quick welding can be performed.
