[0002] In the process of processing copper bars inside electrical appliances such as refrigerators and air conditioners, in order to meet different installation requirements, it is inevitable to process some special-shaped copper bars. At present, the copper bars are fixed by using bench vises. However, ordinary bench vises can only clamp and fix copper bars with smooth edges, but when it is necessary to fix copper bars with uneven edges, the fixing effect is poor. Therefore, we propose an adjustable fixing device for processing special-shaped copper bars to solve the above problems. Utility Model Content

The fixed blocks are slidably matched with the base, and limit plates are arranged on both sides of the fixed block, and a cover plate is arranged above the fixed block, and the cover plate is fixedly connected to the limit plate.

[0007] As a preferred technical solution of the utility model, a connecting seat is rotatably mounted on the inner end of the screw rod via a bearing, and the connecting seat is rotatably connected to the extrusion block via a rotating shaft.

[0008] As a preferred technical solution of the utility model, both ends of the extrusion block are provided with beveled surfaces, and the two fixed blocks are provided with inclination angles adapted to the beveled surfaces. The setting of the inclined surfaces and the inclination angles facilitates the movement of the fixed blocks when the extrusion block rotates.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 , an adjustable fixing device for processing special-shaped copper bars, comprising a base 1, a front block 2 and a rear block 3 are respectively arranged at both ends of the base 1, the front block 2 and the rear block 3 are both fixedly connected to the base 1, wherein a rotating knob 4 is rotatably mounted on the side of the rear block 3 away from the front block 2, a threaded hole is arranged in the middle of the rotating knob 4, a screw rod 5 is inserted in the rotating knob 4, the screw rod 5 is threadedly connected to the rotating knob 4, and the screw rod 5 passes through the rear block 3 and slides with the rear block 3;

[0021] The inner end of the screw rod 5 is rotatably mounted with a connecting seat 7 through a bearing, and the connecting seat 7 is rotatably connected to the extrusion block 6 through a rotating shaft. Fixed blocks 8 are provided at both ends of the extrusion block 6. The fixed block 8 is located on the side of the extrusion block 6 away from the rear stopper 3. The fixed block 8 is slidably matched with the base 1, and limit plates 9 are provided on both sides of the fixed block 8. The moving direction of the fixed block 8 is limited by the limit plates 9 so that it can only move forward and backward, and a cover plate 12 is provided above the fixed block 8, and the cover plate 12 is fixedly connected to the limit plate 9.

[0022] Among them, both ends of the extrusion block 6 are provided with beveled surfaces, and the two fixing blocks 8 are provided with inclined angles adapted to the beveled surfaces. The setting of the inclined surfaces and the inclined angles facilitates the movement of the fixing blocks 8 when the extrusion block 6 rotates.

[0023] Furthermore, an adjusting block 10 is inserted at one end of the fixed block 8 away from the extrusion block 6. The outer end of the adjusting block 10 is arranged in an arc shape, which is convenient for contacting with the curved surface at the edge of the copper busbar to improve the fixing effect. The adjusting block 10 is slidably connected to the fixed block 8, and a plurality of adjusting holes 101 are provided on the upper surface of the adjusting block 10. The adjusting holes 101 are arranged linearly, and a pin shaft 11 adapted to the adjusting hole 101 is inserted on the fixed block 8. By changing the pin shaft 11 to be inserted in different adjusting holes 101, the exposed length of the adjusting block 10 can be changed, so as to facilitate the fixation of the copper busbar with a large edge unevenness. The pin shaft 11 passes through the cover plate 12, and a waist groove 13 is provided on the cover plate 12. The pin shaft 11 is inserted in the waist groove 13. The waist groove 13 provides a movable space for the pin shaft 11, so that when the fixed block 8 moves, the pin shaft 11 can move at the same time.

[0024] In this embodiment: when the device is in use, the pin shaft 11 is pulled out, and the exposed length of the adjustment block 10 is adjusted according to the demand, and after the adjustment, the pin shaft 11 is inserted into the adjustment hole 101 again to fix the adjustment block 10;

[0025] By rotating the rotating knob 4, the rotating knob 4 drives the screw rod 5 to move inward, and drives the extrusion block 6 and the fixed block 8 to move. When the adjustment block 10 on one side contacts the edge of the copper bar, the extrusion block 6 rotates, so that the fixed adjustment block 10 on the other side continues to move toward the copper bar until it contacts the edge of the copper bar, thereby fixing the edge of the copper bar by two fixed points, which improves the fixing effect of the special-shaped copper bar compared with the conventional bench vise.
