Description

Technical Field

[0001] The invention belongs to the technical field of adjusting equipment, and in particular relates to an automatic adjusting fixture. Background Art

[0002] During the wire processing, raw materials such as copper and aluminum are generally put into a wire drawing machine for stretching, and then annealed, reamed, and pressed. An insulating layer is wrapped around the outside of the raw material to form a wire, and then a shielding layer is covered on the outside of the insulating layer. When the wire processing is completed, it is generally rolled up using a winding device. The general winding device includes a frame, a winding drum rotatably arranged on the frame, and a motor arranged on the frame to drive the winding drum to rotate. The motor is started, and the motor drives the winding drum to rotate. The wire is wound and rolled around the outside of the winding drum. However, during the winding process, the wire needs to be tensioned to avoid wire entanglement. At present, there is no specific wire tensioning mechanism. At the same time, how to accurately adjust is also a pain point of the current tensioning equipment. Summary of the invention

[0003] Purpose of the invention: The purpose of the present invention is to provide an automatic adjustment fixture to solve the technical problems of wire tensioning and precise tensioning.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: an automatic adjustment fixture, characterized in that: it includes:

[0005] A base; a movable shaft longitudinally extending through the base;

[0006] a first fixing member, the first fixing member sequentially passing through the machine base and the movable shaft;

[0007] A thread passing ring, which is sleeved on the movable shaft and rotates, has a second fixing member installed on both sides of the front and rear of the thread passing ring, and the thread passing ring is sleeved on the movable shaft through a bearing;

[0008] The second fixing member is fixed to the movable shaft by bolts.

[0009] Furthermore: a sliding seat with a protrusion is fixedly installed on the upper surface of the base away from the movable shaft;

[0010] A cover plate, wherein the cover plate has a groove matching the protrusion;

[0011] The third fixing member passes through the protrusion and the groove in sequence for fixing.

[0012] Further: a first fixing block is installed on the side of the cover plate, an adjusting nut is built in the first fixing block, and a second fixing block is installed on the sliding seat;

[0013] A fine-tuning screw rod is connected to the threaded section and the knob section in sequence, and one end of the fine-tuning screw rod away from the threaded section is inserted into the second fixed block through a rotating shaft bearing.

[0014] Furthermore: a spring is provided between the second fixing member and the threading ring.

[0015] Compared with the prior art, the present invention has the following advantages: the position of the wire ring sleeved on the movable shaft is limited by using the second fixing member, and the spring can be compressed or released by using the distance between the second fixing member and the wire ring during the limitation, so as to achieve the function of adjusting the sliding compensation displacement of the wire ring;

[0016] On the other hand, the third fixing part is removed by turning the knob, and the knob section is rotated to allow the threaded section to step to one side along the adjusting nut, thereby allowing the fine-tuning screw to drive the machine base forward or backward for precise adjustment, which has good applicability and promotion.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] In the description of the invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] In one embodiment of the present invention, Figure 1 As shown, an automatic adjustment fixture includes:

[0023] A base 1; a movable shaft 2 longitudinally penetrating the base 1;

[0024] A first fixing member 3, the first fixing member 3 sequentially passes through the base 1 and the movable shaft 2;

[0025] A thread ring 4 is sleeved on the movable shaft 2, and a second fixing member 5 is installed on both sides of the front and rear of the thread ring 4 for rotation. The thread ring 4 is sleeved on the movable shaft 2 through a bearing 7;

[0026] The second fixing member 5 is fixed to the movable shaft 2 by bolts;

[0027] A sliding seat 8 having a protrusion 9 is fixedly mounted on the upper surface of the base 1 away from the movable shaft 2;

[0028] A spring 6 is provided between the second fixing member 5 and the thread ring 4 .

[0029] By adopting the above technical solution, the implementation method of the utility model is as follows: firstly, the movable shaft 2 is inserted into the machine base 1 according to the demand, and the movable shaft 2 is fixed on the machine base 1 by the first fixing member 3;

[0030] After the position of the movable shaft 2 is fixed, a second fixing member 5 is sleeved on the movable shaft 2, and the thread ring 4 is sleeved on the movable shaft 2 to fit with the second fixing member 5, and the second fixing member 5 is fixed by bolts at the adapted position, thereby restricting one side of the thread ring 4, and the thread ring 4 is sleeved on the movable shaft 2 through a bearing;

[0031] The spring 6 is sleeved on the movable shaft 2 and abutted against the other end of the thread ring 4. The spring 6 is squeezed by the second second fixing member 5 to adjust the elastic compensation displacement distance of the thread ring 4. Finally, the second fixing member 5 is fixed at the appropriate position by bolts.

[0032] In another embodiment of the present invention, Figure 1-Figure 3 As shown, an automatic adjustment fixture includes a cover plate 10, wherein the cover plate 10 has a groove 11 matching the protrusion 9;

[0033] A third fixing member 12, the third fixing member 12 sequentially passes through the protrusion 9 and the groove 11 for fixing;

[0034] A first fixing block 13 is installed on the side of the cover plate 10, an adjusting nut 19 is built in the first fixing block 13, and a second fixing block 14 is installed on the sliding seat 8;

[0035] The fine-tuning screw 15 is connected to the threaded section 16 and the knob section 17 in sequence, and one end of the fine-tuning screw 15 away from the threaded section 16 is inserted into the second fixing block 14 through the rotating shaft bearing.

[0036] By adopting the above technical scheme, the implementation method of the utility model is as follows: when in use, the third fixing member 12 can be unscrewed to disengage the cover plate 10 from the protrusion 9, and then the knob section 17 is rotated to make the threaded section 16 step in one direction along the adjusting nut 19. At this time, the rotation direction of the knob section 17 is determined, so that the base 1 is driven to step forward and then retreat to complete the movement through the fine-tuning screw 15. In the above scheme, precise adjustment can be achieved by marking scales on the knob section 17.
