[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] A copper piece parallel positioning jig comprises a movable frame 1 and a tubular copper piece 2, wherein a groove is provided on the top of the movable frame 1, and bearing plates 3 are fixedly connected to both sides of the inner wall of the groove, and the top of the bearing plate 3 is a curved surface for providing support for the tubular copper piece 2 from below, and two clamping plates 4 that can move toward each other are provided at both ends of the tubular copper piece 2 and between the two bearing plates 3, and the two clamping plates 4 are arranged in parallel for clamping the tubular copper piece 2 from both ends.

[0027] The inner wall of the tubular copper part 2 is provided with a positioning groove 201, and a positioning pressure plate 5 is arranged in the positioning groove 201. Both ends of the positioning pressure plate 5 pass through the tubular copper part 2 and extend to the outside of the tubular copper part 2. A positioning slot 6 is provided on the top of the clamping plate 4, and the positioning slot 6 and the positioning pressure plate 5 are adapted to each other.

[0028] like Figure 2 and Figure 3The tubular copper piece 2 with a positioning groove 201 on the inner wall is a prior art. When it is sleeved on the outside of another pipe, it can be engaged with the protrusion on the surface of the other pipe to prevent the tubular copper piece 2 and the other pipe from rotating relative to each other when they are sleeved. The tubular copper piece 2 is supported by two supporting plates 3 so that the tubular copper piece 2 will not fall into the groove of the movable frame 1, and the positioning pressure plate 5 is inserted into the inside of the positioning slot 6.

[0029] The positioning platen 5 is provided with fixing holes 7 in a linear array, and the positioning platen 5 is provided with fixing bolts 8, which pass through the fixing holes 7 and are threadedly connected to the clamping plate 4, so as to fix the positioning platen 5 and the clamping plate 4 together.

[0030] like Figure 2 , Figure 3 and Figure 4 A threaded hole is provided on the inner wall of the positioning slot 6 of the clamping plate 4, so that the fixing bolt 8 can be connected with the threaded hole, so that the fixing bolt 8 passes through the fixing hole 7 and is threadedly connected with the clamping plate 4, fixing the clamping plate 4 and the positioning pressure plate 5 together to prevent the positioning pressure plate 5 from moving up and down or horizontally.

[0031] Two limiting protrusions 9 are fixedly connected in the groove of the movable frame 1, a limiting cylinder 10 is arranged between the two limiting protrusions 9, and a forward screw 11 and a reverse screw 12 are fixedly connected to the two ends of the limiting cylinder 10 respectively. The forward screw 11 and the reverse screw 12 respectively penetrate the two limiting protrusions 9 and extend to the outside of the limiting protrusions 9.

[0032] like Figure 2 and Figure 4 The limiting cylinder 10 is located between the two limiting protrusions 9, which can prevent the limiting cylinder 10 from moving horizontally. At the same time, the forward screw 11 and the reverse screw 12 are fixedly connected to the limiting cylinder 10, so that the forward screw 11 and the reverse screw 12 will not move horizontally, and the forward screw 11, the reverse screw 12 and the limiting cylinder 10 can rotate together.

[0033] The forward screw rod 11 and the reverse screw rod 12 are both threadedly connected with a movable block 13 , and the top of the movable block 13 is fixedly connected to the clamping plate 4 to drive the two clamping plates 4 to move toward each other.

[0034] like Figure 2 and Figure 4 The thread directions of the forward screw 11 and the reverse screw 12 are opposite, so that when the forward screw 11 and the reverse screw 12 rotate in the same direction, the two movable blocks 13 can move closer to or farther away from each other, and the movable blocks 13 drive the two clamping plates 4 to move closer to or farther away from each other.

[0035] The ends of the forward screw rod 11 and the reverse screw rod 12 that are away from each other are fixedly connected to a control handle 14 , and the control handle 14 is provided with anti-slip grooves.

[0036] like Figure 2 and Figure 4 , by manually turning the control handle 14 with anti-slip grooves.

[0037] A fixed plate 15 is provided at the bottom of the movable frame 1, and a sliding guide component 16 is fixedly connected to the top of the fixed plate 15. A sliding guide groove 17 is opened on the movable frame 1, and the sliding guide groove 17 is slidably connected to the sliding guide component 16. Limiting protrusions 18 are fixedly connected to the top of the sliding guide component 16 and at both ends of the movable frame 1.

[0038] like Figure 1 , Figure 4 and Figure 5 The position of the movable frame 1 can be adjusted by the sliding connection between the sliding guide component 16 and the sliding guide groove 17, and the limiting protrusion 18 can limit the maximum distance of the movable frame 1.

[0039] The working principle of a copper part parallel positioning fixture provided by the utility model is as follows:

[0040] By manually rotating the control handle 14 in different directions, the forward screw 11, the reverse screw 12 and the limiting cylinder 10 can be driven to rotate in different directions together, so that the two clamping plates 4 are moved closer to or away from each other. When the two clamping plates 4 are moved closer to each other, the tubular copper piece 2 is clamped from both sides. At this time, the positioning plate 5 is inserted into the positioning groove 201 to position the tubular copper piece 2.

[0041] On the contrary, the positioning pressing plate 5 is removed from the tubular copper member 2, and then the control handle 14 is turned so that the two clamping plates 4 are away from each other, and then the tubular copper member 2 can be removed.

[0042] Compared with the related art, the copper part parallel positioning fixture provided by the utility model has the following beneficial effects:

[0043] The utility model clamps the tubular copper piece 2 from both ends by two parallel clamping plates 4, and then inserts the positioning pressure plate 5 into the positioning groove 201 of the tubular copper piece 2, and the positioning pressure plate 5 is inserted into the positioning groove 6 of the clamping plate 4, so that the positioning pressure plate 5 will not rotate. When the positioning pressure plate 5 positions the tubular copper piece 2, the tubular copper piece 2 will not rotate relative to the positioning pressure plate 5, thereby realizing rapid positioning of the tubular copper piece 2 and avoiding the tubular workpiece 2 from rotating, which would cause an error in the required processing position when processing the tubular workpiece.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
