Description

Technical Field

[0001] The utility model relates to the technical field of electromagnet processing, in particular to a point-locking machine with a protective structure. Background Art

[0002] Electromagnets require varying currents to generate varying forces, allowing the armature to remain in different positions, enabling precise control of valve flow and meeting diverse customer requirements. However, key parameters such as magnetic hysteresis and force hysteresis can affect the electromagnet's practical value.

[0003] When processing the existing electromagnet sleeve, it is generally necessary to use an arc-shaped clamp with a convex point on the outer periphery of the circumference to move and squeeze toward the center, and finally achieve a pressure point operation on the outer surface of the electromagnet sleeve at the center. By pressing the point on its surface, the precise positioning of the electromagnet can be facilitated, and the local strength of the electromagnet can also be enhanced at the pressure point, thereby improving the service life of the electromagnet.

[0004] However, in actual use of the above-mentioned equipment, since the buckling point processing of the electromagnet generally adopts manual loading, and the buckling point process after loading is carried out due to mechanical movement, the electromagnet sleeve may be skewed or offset due to shaking, which in turn leads to a decrease in the buckling point accuracy of the electromagnet sleeve and affects the processing quality of the electromagnet; in view of this, we propose a buckling point machine with a protective structure. Utility Model Content

[0005] The purpose of the present invention is to provide a buckle point machine with a protective structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a buckle point machine with a protective structure, comprising a machine body, a hydraulic cylinder fixedly mounted on the inner wall of the machine body, a disc fixedly mounted on the output end of the hydraulic cylinder, a circular cavity provided on the top inner wall of the machine body, a fixing ring fixedly mounted on the inner wall of the circular cavity, a guide plate fixedly mounted on the arc-shaped inner surface of the fixing ring, a guide groove provided on the inner wall of the guide plate, a pressure block slidably mounted on the upper surface of the disc, a transmission groove with a width matching the width of the guide plate provided on the inner wall of the pressure block, a guide column fixedly mounted on the inner wall of the transmission groove, the guide column being arranged inside the guide groove, a pressing assembly provided inside the pressure block, and the pressing assembly comprising:

[0007] A T-shaped slot is provided on the upper surface of the disc, a T-shaped slider is fixedly mounted on the lower surface of the pressing block, a hinge groove is provided on the upper surface of the disc, an extension rod is hingedly connected to the inner wall of the hinge groove, and a swing rod is movably connected to the top end of the extension rod;

[0008] A straight slot is provided on the inner wall of the swing rod, a round rod is provided inside the straight slot, a rotating rod is passed through and fixedly installed on the inner wall of the top end of the swing rod, the end of the rotating rod is rotatably connected to the abutment plate, and a spiral spring is sleeved on the arc-shaped outer wall of the rotating rod.

[0009] Preferably, the outer diameter of the disc is adapted to the inner diameter of the circular cavity, so that under the drive of the hydraulic cylinder, the disc can only move in the vertical direction along the inner wall of the circular cavity, thereby realizing the lifting of the disc, and a circular hole is opened at the center of the disc to facilitate the insertion of the electromagnet sleeve.

[0010] Preferably, the number of the guide plates is set in multiple groups, and each group of guide plates is provided with two pieces, the two guide plates are symmetrically arranged with the vertical central axis of the pressure block as the symmetry axis, and the multiple groups of guide plates are evenly distributed in a circular array on the arc-shaped inner surface of the fixed ring, the number of the pressure blocks is set in eight groups, and the eight groups of pressure blocks are evenly distributed in a circular array on the upper surface of the disc, so that the eight groups of pressure blocks can form a circular structure when they are close to each other, thereby realizing the extrusion and buckling work on the outer side of the sleeve of the electromagnet.

[0011] Preferably, a square rod is provided on the top of the extension rod, and a square groove adapted to the square rod is provided on the inner wall of the bottom end of the swing rod, so that the extension rod can drive the swing rod to rotate without motion interference.

[0012] Preferably, a protection component is provided inside the abutment plate, and the protection component includes a rotation groove, which is opened on the bottom inner wall of the abutment plate, a baffle is fixedly installed on the top inner wall of the rotation groove, a stopper is fixedly installed on the top outer wall of the swing rod, and a rubber ball is fixedly installed on the lower surface of the abutment plate, and a spiral groove is opened on the spherical surface of the rubber ball.

[0013] Preferably, the rotating rod is rotatably installed inside the rotating groove, and a circular cavity with a diameter larger than the outer diameter of the spiral spring is opened on the inner walls at both ends of the rotating groove. At the same time, the two ends of the spiral spring are fixedly connected to the bottom inner wall of the circular cavity and the arc-shaped outer wall of the rotating rod, so that the rotating rod always has a reverse rotation and reset movement tendency when rotating with the abutment plate.

[0014] Compared with the prior art, the present invention provides a buckle point machine with a protective structure, which has the following beneficial effects:

[0015] 1. The buckle point machine with a protective structure is provided with a tightening component. Through the influence of the round rod on the straight slot and the swing rod, the spiral spring and the rotating rod provided on the top of the swing rod are coordinated, so that the abutment plate contacts the top surface of the electromagnet sleeve first and produces a tightening effect on it, ensuring that it will not tilt or deflect before the buckle point operation, and thus the dangerous situation of collapse and flying will not occur in the subsequent extrusion buckle point process, thereby improving the safety of the equipment during processing.

[0016] 2. The buckle point machine with a protective structure is equipped with a protective component, which cooperates with the baffle and the block. When the abutment plate contacts the top of the electromagnet sleeve, even if it encounters a flying situation during the processing, the maximum outward deflection angle of the abutment plate will be limited, thereby avoiding the situation where the top of the machine body is blocked and empty, posing a threat to the safety of surrounding workers.

[0025] In one embodiment of the present utility model, a T-shaped slot 91 is provided on the upper surface of the disc 3, a T-shaped slider 92 is fixedly installed on the lower surface of the pressure block 8, a hinge groove 93 is provided on the upper surface of the disc 3, an extension rod 94 is hingedly connected to the inner wall of the hinge groove 93, and a swing rod 95 is movably connected to the top of the extension rod 94, a straight slot 96 is provided on the inner wall of the swing rod 95, a round rod 97 is provided inside the straight slot 96, a rotating rod 98 is passed through and fixedly installed on the inner wall of the top end of the swing rod 95, the end of the rotating rod 98 is rotatably connected to the abutment plate 99, and a spiral spring 910 is sleeved on the arc-shaped outer wall of the rotating rod 98.

[0026] Furthermore, ventilation holes are provided on the front and back of the body 1 to facilitate the normal operation of the hydraulic cylinder 2. At the same time, the outer diameter of the disc 3 is adapted to the inner diameter of the circular cavity, so that under the drive of the hydraulic cylinder 2, the disc 3 can only move in the vertical direction along the inner wall of the circular cavity, thereby realizing the lifting of the disc 3, and a circular hole is provided at the center of the disc 3 to facilitate the insertion of the electromagnet sleeve, thereby facilitating the subsequent buckling operation. At the same time, the number of guide plates 5 is provided in multiple groups, and each group of guide plates 5 is provided with two pieces. The two guide plates 5 are symmetrically arranged with the vertical central axis of the pressure block 8 as the symmetry axis, and the multiple groups of guide plates 5 are evenly distributed in a circular array. Arranged on the arc-shaped inner surface of the fixing ring 4, specifically, the number of the pressure blocks 8 is set to eight groups, and the eight groups of pressure blocks 8 are evenly distributed in a circular array on the upper surface of the disc 3, so that the eight groups of pressure blocks 8 can form a circular ring structure when they are close to each other, thereby realizing the extrusion and buckling work on the outer side of the electromagnet sleeve. Specifically, the number of the guide columns 7 is set to two groups, and the two groups of guide columns 7 are both arranged inside the guide groove 6, so that as the disc 3 rises, the guide columns 7 move in the guide groove 6, so that the pressure blocks 8 will move horizontally toward the center of the disc 3 while rising with the disc 3, thereby realizing the buckling point processing of the electromagnet sleeve.

[0027] In addition, the T-shaped slider 92 is adapted to the size of the T-shaped slot 91, thereby limiting the pressing block 8 to only linear motion on the disc 3. At the same time, a rectangular slot with a width adapted to the width of the extension rod 94 is provided on the inner wall of the pressing block 8, and a round rod 97 is provided in the rectangular slot. When the pressing block 8 is affected by the guide plate 5, the guide slot 6 and the guide column 7 and slides along the upper surface of the disc 3 toward the center of the disc 3, the round rod 97 affects the straight slot 96 to prompt the swinging rod 95 to rotate toward the center of the disc 3 with the hinge point of the extension rod 94 and the hinge slot 93 as the rotation center. During the process, since a square rod is provided on the top of the extension rod 94, and a square groove adapted to the square rod is opened on the inner wall of the bottom end of the swing rod 95, the extension rod 94 can drive the swing rod 95 to rotate without motion interference, and before the pressure block 8 contacts the outer surface of the electromagnet sleeve, the abutment plate 99 first contacts the top of the electromagnet sleeve under the elastic force of the spiral spring 910, and produces a downward fitting effect, ensuring that it will not tilt or deflect before the buckling operation, and then there will be a dangerous situation of collapse and flying during the subsequent extrusion buckling process, thereby improving the safety of the equipment during processing.

[0028] In an embodiment of the present utility model, a protective component 10 is provided inside the abutment plate 99, and the protective component 10 includes a rotating groove 101, which is opened on the bottom inner wall of the abutment plate 99, and a baffle 102 is fixedly installed on the top inner wall of the rotating groove 101, and a stopper 103 is fixedly installed on the top outer wall of the swing rod 95. A rubber ball 104 is fixedly installed on the lower surface of the abutment plate 99, and a spiral groove 105 is opened on the spherical surface of the rubber ball 104.

[0029] Specifically, the rotating rod 98 is rotatably installed inside the rotating groove 101, and a circular cavity with a diameter larger than the outer diameter of the spiral spring 910 is opened on the inner walls at both ends of the rotating groove 101. At the same time, the two ends of the spiral spring 910 are fixedly connected to the inner wall of the bottom end of the circular cavity and the arc-shaped outer wall of the rotating rod 98, so that the rotating rod 98 always has a tendency to rotate in the opposite direction to achieve reset when rotating with the abutment plate 99. At the same time, the stopper 103 and the baffle 102 are arranged in the same plane, thereby limiting the maximum outward deflection angle of the abutment plate 99 to avoid possible accidents that may cause it to deflect at a large angle, exposing the gap at the top of the machine body 1. When the abutment plate 99 contacts the top of the electromagnet sleeve, the rubber ball 104 first contacts the electromagnet sleeve, and increases the static friction coefficient between the two through the setting of the spiral groove 105, so as to better ensure the feeding safety of the electromagnet sleeve.

[0030] When the cam 98 is in operation, the guide plate 97 is in operation, and the guide plate 97 is in operation, so that the guide plate 97 is in operation, and the guide plate 97 is in operation. When the cam 98 is in operation, the guide plate 97 is in operation, and the guide plate 97 is in operation, so that the guide plate 97 is in operation, and the guide plate 97 is in operation, so that the guide plate 97 is in operation, and the guide plate 97 is in operation.

[0031] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
