Description

Technical Field

[0001] The utility model relates to the technical field of wire screw sleeve processing, in particular to a cutting device for forming a tailless wire screw sleeve. Background Art

[0002] A wire thread insert is a tool used to repair and strengthen threads. Typically made of stainless steel or alloy steel, it features a helical structure. When a threaded hole is damaged or loose, it can be installed into the original thread to restore its original specifications and strength. It is particularly suitable for softer or more delicate materials. Installing a wire thread insert improves thread durability and load-bearing capacity, making it a valuable repair and reinforcement tool in a wide range of applications, including machinery manufacturing, the automotive industry, and aerospace.

[0003] The Chinese patent publication number CN216938163U discloses a wire screw tail wire cutting device. The device can drive the top plate to move by shortening the electric telescopic rod, and the top plate can drive the electromagnet to move. The electromagnet sucks the workpiece and moves the workpiece back to the workpiece conveyor. The wire screw tail wire cutting device has a simple structure and is easy to operate. It can continuously process the workpiece, making the processing speed faster.

[0004] The above patent uses a top plate to push one end of the workpiece into the outside of the positioning and cutting seat to achieve clamping and positioning of the workpiece. However, since the wire screw sleeve is similar to a spring and has a certain elasticity, if the extrusion force at both ends is small, the fixing effect is poor, and it is easy to shift during the cutting process, thereby affecting the product quality. If the extrusion force is large, although it can enhance the fixing effect, it will cause the gap of the wire screw sleeve to shrink to a very small or even completely closed, thereby increasing the risk of accidentally cutting adjacent wires during the cutting operation, resulting in unqualified products. Utility Model Content

[0005] The utility model aims to provide a cutting device for forming a tailless wire screw sleeve, so as to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the technical solution of the present utility model is as follows.

[0007] A cutting device for forming a tailless wire screw insert comprises a base plate, a workpiece conveyor mounted on the upper surface of the base plate, a first vertical plate mounted on one side of the upper surface of the base plate, a first electric push rod mounted on the outer surface of the first vertical plate, a push rod disposed at the end of the telescopic end of the first electric push rod, and an electromagnet mounted on the end of the push rod. A second vertical plate is mounted on the other side of the upper surface of the base plate, a positioning rod mounted on the outer surface of the second vertical plate, a plurality of arc-shaped plates arranged in a coaxial array on the outer surface of the positioning rod, and an external support mechanism capable of driving the multiple arc-shaped plates to support the outside is disposed within the positioning rod. A mounting top plate is mounted on the top of the second vertical plate, a second electric push rod mounted on the top of the mounting top plate, and a cutter is disposed at the end of the telescopic end of the second electric push rod.

[0008] It can be seen that when the wire screw sleeve is pushed onto the outer surface of the positioning rod, the multiple arc plates can be driven to be pushed outward at the same time through the external support mechanism, so that the wire screw sleeve can be clamped and fixed from the inside, which not only has a good fixing effect, but also can avoid displacement during the cutting process, and will not cause compression of the wire screw sleeve, thereby avoiding the risk of accidentally cutting adjacent wires during the cutting operation and improving product quality.

[0009] Furthermore, the external support mechanism includes a guide rod connected to the lower surface of the arc plate, the end of the guide rod passes through the interior of the positioning rod and is installed with a wedge plate, the outer surface of the second vertical plate is installed with a U-shaped plate, the outer surface of the U-shaped plate is installed with a third electric push rod, and the end of the telescopic end of the third electric push rod is provided with a tapered rod, and the end of the tapered rod is provided in the positioning rod.

[0010] When the third electric push rod is started, its telescopic end drives the tapered rod to be inserted deep into the positioning rod and squeezes the multiple wedge plates, so that the multiple arc plates can be pressed against the inner side of the wire screw sleeve for fixation through the connecting action of the guide rod.

[0011] Furthermore, a spring is sleeved on the outer surface of the guide rod, and two ends of the spring are respectively in contact with the inner wall of the positioning rod and the wedge plate.

[0012] When the wedge-shaped plate drives the arc plate to press against the inner side of the wire screw sleeve, the wedge-shaped plate will compress the spring. When the third electric push rod drives the tapered rod to be pulled out, the squeezing of the tapered rod on the wedge plate disappears. At this time, the compressed spring releases its elastic force, thereby driving the arc plate to reset and canceling the fixation of the wire screw sleeve, making it easier to remove it from the positioning rod.

[0013] Furthermore, there are multiple push rods, positioning rods, tapered rods and cutters. A first mounting plate is installed at the end of the telescopic end of the first electric push rod, and multiple push rods are equidistantly installed on the outer surface of the first mounting plate. A second mounting plate is installed at the end of the telescopic end of the third electric push rod, and multiple tapered rods are equidistantly installed on the outer surface of the second mounting plate. A third mounting plate is installed at the end of the telescopic end of the second electric push rod, and multiple cutters are equidistantly arranged on the outer surface of the third mounting plate.

[0014] The number of the push rod, positioning rod, tapered rod and cutter can be 3, 4, 5, etc., so that multiple wire screw inserts can be cut at the same time, greatly improving production efficiency.

[0015] Furthermore, a mounting sleeve is installed at the end of the cutter, a bump is installed on the outer surface of the third mounting plate, and the mounting sleeve and the bump are connected by bolts.

[0016] Since the cutter is a consumable part, it can be quickly replaced through bolt connection, which reduces downtime and improves production efficiency.

[0017] Furthermore, limiting rods are installed on both sides of the outer surface of the first mounting plate, and limiting sleeves are installed on both sides of the outer surface of the first vertical plate, and the limiting sleeves are arranged on the outer surfaces of the limiting rods.

[0018] By setting the limiting rod and the limiting sleeve, the limiting effect of the first mounting plate can be improved, so that it can drive the push rod to accurately push the wire screw sleeve from the inside of the workpiece positioning groove on the workpiece conveying part to the outside of the positioning rod.

DETAILED DESCRIPTION

[0027] The present invention is described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-7 As shown, a cutting device for forming a tailless wire screw insert includes a base plate 100, a workpiece conveyor 101 mounted on the upper surface of the base plate 100, a first vertical plate 102 mounted on one side of the upper surface of the base plate 100, a first electric push rod 103 mounted on the outer surface of the first vertical plate 102, a push rod 104 disposed at the end of the telescopic end of the first electric push rod 103, and an electromagnet 105 mounted on the end of the push rod 104. A second vertical plate 106 is mounted on the other side of the upper surface of the base plate 100, a positioning rod 107 mounted on the outer surface of the second vertical plate 106, a plurality of arc-shaped plates 108 arranged in a coaxial array on the outer surface of the positioning rod 107, and an external support mechanism 200 disposed within the positioning rod 107 that can drive the plurality of arc-shaped plates 108 to support the outer surface. A mounting top plate 109 is mounted on the top of the second vertical plate 106, a second electric push rod 110 mounted on the top of the mounting top plate 109, and a cutter 111 disposed at the end of the telescopic end of the second electric push rod 110.

[0029] During use, the first electric push rod 103 drives the push rod 104 to push the wire screw sleeve inside the workpiece positioning groove on the workpiece conveying member 101 to the outside of the positioning rod 107, and then drives multiple arc plates 108 to be simultaneously opened outward through the external support mechanism 200 and clamps the wire screw sleeve from the inside. Not only is the fixing effect good, it can also avoid displacement during the cutting process and will not cause compression of the wire screw sleeve, thereby avoiding the risk of accidentally cutting adjacent steel wires during the cutting operation and improving product quality. After cutting, the wire screw sleeve is moved back to the workpiece conveying member 101 by the electromagnet 105.

[0030] Specifically, the external support mechanism 200 includes a guide rod 201 connected to the lower surface of the arc plate 108, the end of the guide rod 201 passes through the interior of the positioning rod 107 and is installed with a wedge plate 202, the outer surface of the second vertical plate 106 is installed with a U-shaped plate 203, the outer surface of the U-shaped plate 203 is installed with a third electric push rod 204, and the end of the telescopic end of the third electric push rod 204 is provided with a tapered rod 205, and the end of the tapered rod 205 is set in the positioning rod 107. When the third electric push rod 204 is started, its telescopic end drives the tapered rod 205 to insert into the deep of the positioning rod 107 and squeezes multiple wedge plates 202. Therefore, the connection action of the guide rod 201 can drive multiple arc plates 108 to be pressed against the inner side of the wire screw sleeve for fixation.

[0031] Specifically, a spring 300 is sleeved on the outer surface of the guide rod 201, and the two ends of the spring 300 are respectively in contact with the inner wall of the positioning rod 107 and the wedge plate 202. When the wedge plate 202 drives the arc plate 108 to press against the inner side of the wire screw sleeve, the wedge plate 202 will compress the spring 300. When the third electric push rod 204 drives the tapered rod 205 to be pulled out, the squeezing of the tapered rod 205 on the wedge plate 202 disappears. At this time, the compressed spring 300 releases its elastic force, thereby driving the arc plate 108 to reset and cancel the fixation of the wire screw sleeve, making it easier to remove it from the positioning rod 107.

[0032] Specifically, the number of the push rod 104, the positioning rod 107, the tapered rod 205 and the cutter 111 is multiple, the end of the telescopic end of the first electric push rod 103 is installed with a first mounting plate 400, and multiple push rods 104 are equidistantly installed on the outer surface of the first mounting plate 400, the end of the telescopic end of the third electric push rod 204 is installed with a second mounting plate 401, and multiple tapered rods 205 are equidistantly installed on the outer surface of the second mounting plate 401, the end of the telescopic end of the second electric push rod 110 is installed with a third mounting plate 402, and multiple cutters 111 are equidistantly arranged on the outer surface of the third mounting plate 402, the number of the push rod 104, the positioning rod 107, the tapered rod 205 and the cutter 111 can be 3, 4, 5, etc., so that multiple wire screw sleeves can be cut at the same time, greatly improving production efficiency.

[0033] Specifically, a mounting sleeve 500 is installed at the end of the cutter 111, and a protrusion 501 is installed on the outer surface of the third mounting plate 402. The mounting sleeve 500 and the protrusion 501 are connected by bolts. Since the cutter 111 is a consumable part, it can be quickly replaced by bolt connection, which reduces production downtime and improves production efficiency.

[0034] Specifically, limiting rods 600 are installed on both sides of the outer surface of the first mounting plate 400, and limiting sleeves 601 are installed on both sides of the outer surface of the first vertical plate 102. The limiting sleeves 601 are set on the outer surface of the limiting rod 600. Through the setting of the limiting rod 600 and the limiting sleeve 601, the limiting effect of the first mounting plate 400 can be improved, so that it can drive the push rod 104 to accurately push the wire screw sleeve from the inside of the workpiece positioning groove on the workpiece conveying part 101 to the outside of the positioning rod 107.

For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and have the same performance or use, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
