Description

Technical Field

[0001] This utility model relates to the field of machining fixtures, specifically a heavy-duty truck gear inserting internal gear fixture. Background Technology

[0002] In the heavy-duty truck manufacturing industry, gears, as the core component of the transmission system, directly affect the performance and reliability of heavy-duty trucks due to their machining accuracy and quality. Among them, internal gears, due to their special structure, place particularly stringent requirements on the fixtures during machining.

[0003] Currently, most gear clamps on the market are designed for ordinary gears and have shortcomings when clamping internal gears in heavy-duty trucks. Traditional clamps mostly use mechanical clamping methods, such as bolt tightening and chuck clamping. These methods require multiple manual adjustments and tightenings during operation, which is not only cumbersome and inefficient, but also makes it difficult to ensure a uniform distribution of clamping force, easily causing gear deformation during processing and affecting machining accuracy. Especially when dealing with internal gears of different sizes, different specifications of clamps or complex adjustments are required, increasing production costs and production cycle.

[0004] Therefore, a new type of internal gear clamp for heavy-duty trucks is needed. Summary of the Invention

[0005] This utility model provides a gear insert clamp for heavy-duty trucks, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heavy-duty truck gear inserter, comprising a magnetic structure and a clamping arm, wherein the clamping arm is fixedly connected to the top outer side of the magnetic structure, the magnetic structure comprising an iron block, and an opening at the bottom of the iron block, wherein an electromagnet is fixed within the opening, wherein: The iron block has a hexagonal frustum structure that is narrower at the top and wider at the bottom. The clamping arm includes an iron support plate, which is provided in three sets. The top and bottom of the iron block are composed of three sets of wide sides and three sets of narrow sides. Therefore, the side of the iron block is divided into a wide face and a narrow face. The three sets of iron support plates correspond to the three sets of wide faces on the side of the iron block.

[0007] Preferably, a first support rod is fixedly connected to the bottom end of the iron block. The first support rod is provided in three sets and is arranged in a ring at equal intervals at the bottom end of the iron block. A counterweight base is fixedly connected to the bottom end of the three sets of the first support rod.

[0008] Preferably, a protective plate is fixedly connected to the end of the iron support plate away from the iron block. The inner and outer sides of the protective plate are both arc-shaped. A counterweight is integrally formed and fixed to the bottom end of the protective plate. The counterweight is designed to bulge outward. The inner walls of the three sets of protective plates are fitted and fixed to the edge of the insert teeth.

[0009] Preferably, the bottom ends of the three sets of iron support plates are rotatably connected to a fixed ring via a rotating shaft. The bottom end of the fixed ring is fixedly connected to a second support rod. The second support rod is provided in three sets and is arranged in a ring at equal intervals at the bottom end of the fixed ring. The bottom ends of the three sets of second support rods are integrally formed and fixed to the top of the counterweight base.

[0010] Preferably, a limiting ring is fitted on the outer wall of the clamping arm. The limiting ring includes a metal ring with openings at both ends. There are three sets of metal rings. A rubber slider is slidably connected between two adjacent sets of metal rings through the openings. The three sets of metal rings correspond to the three sets of guard plates. The outer wall of the guard plate fits against the inner wall of the metal ring. The limiting ring limits the outer side of the clamping arm.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model uses an electromagnet to generate magnetic attraction to an iron support plate, combined with a hexagonal iron block and a counterweight base, to effectively avoid shaking during the clamping process, improve clamping stability, and ensure processing accuracy.

[0012] 2.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figure 1-3 As shown, a heavy truck gear inserter includes a magnetic structure 1 and a clamping arm 2. The clamping arm 2 is fixedly connected to the top outer side of the magnetic structure 1. The magnetic structure 1 includes an iron block 14. The bottom end of the iron block 14 has a set of openings, and an electromagnet 13 is fixed in the openings.

[0018] The iron block 14 has a hexagonal frustum structure that is narrow at the top and wide at the bottom. The clamping arm 2 includes an iron support plate 21, which is provided in three sets. The top and bottom of the iron block 14 are composed of three sets of wide sides and three sets of narrow sides. Therefore, the side of the iron block 14 is divided into a wide surface and a narrow surface. The three sets of iron support plates 21 correspond to the three sets of wide surfaces on the side of the iron block 14.

[0019] It should be noted that when the electromagnet 13 is energized, the electromagnet 13 drives the iron block 14 to generate magnetism, attracting the three sets of iron support plates 21. At this time, the insert teeth placed on the surface of the clamping arm 2 can be clamped and fixed.

[0020] In one embodiment of this utility model, such as Figures 1-3 As shown, the bottom end of the iron block 14 is fixedly connected to a first support rod 12. The first support rod 12 is provided in three sets and is arranged in a ring at equal intervals at the bottom end of the iron block 14. The bottom ends of the three sets of first support rods 12 are fixedly connected to a counterweight base 11.

[0021] Specifically, the counterweight base 11 lowers the overall center of gravity, and the first support rod 12 can limit and fix the iron block 14 and the electromagnet 13, so as to prevent the electromagnet 13 from shaking when the iron block 14 is attracted to the iron support plate 21 after being energized, thus enhancing the overall stability.

[0022] In one embodiment of this utility model, such as Figures 1-3 As shown, a guard plate 22 is fixedly connected to the end of the iron support plate 21 away from the iron block 14. The inner and outer sides of the guard plate 22 are both arc-shaped. A counterweight block 23 is integrally formed and fixed at the bottom of the guard plate 22. The counterweight block 23 is designed to protrude outward. The inner walls of the three sets of guard plates 22 are fitted and fixed to the edge of the insert teeth.

[0023] Specifically, the arc-shaped guard plate 22 can fit tightly against the edge of the insert tooth placed therein. If the guard plate 22 is square, it cannot fit well against the edge of the insert tooth when clamping and fixing.

[0024] In one embodiment of this utility model, such as Figures 1-3 As shown, the bottom ends of the three sets of iron support plates 21 are all rotatably connected to fixed rings 24 via rotating shafts. The bottom ends of the fixed rings 24 are fixedly connected to second support rods 15. The second support rods 15 are provided in three sets and are arranged in a ring at equal intervals at the bottom ends of the fixed rings 24. The bottom ends of the three sets of second support rods 15 are integrally formed and fixed to the top of the counterweight base 11.

[0025] Specifically, during use, after the electromagnet 13 is energized, the iron block 14 attracts the three sets of iron support plates 21 toward the center. Under the action of the rotating shaft, the three sets of iron support plates 21 rotate toward the iron block 14. At this time, the insert teeth are placed in the center of the clamping arm 2, and the three sets of guard plates 22 are simultaneously rotated and lifted, which can clamp and fix the edge of the insert teeth. After being energized, under the action of magnetic force, the iron support plates 21 always rotate toward the iron block 14, so they can cooperate with insert teeth of different sizes. If the diameter of the insert teeth is larger, the angle at which the guard plates 22 are lifted is smaller, so as to fit and fix with the edge of the insert teeth. If the diameter of the insert teeth is smaller, the angle at which the guard plates 22 are lifted is larger. When the iron support plates 21 are completely attracted to the wide side of the iron block 14, the lifting angle of the guard plates 22 is the largest. The design of attracting the iron support plates 21 by using the wide side of the iron block 14 can increase the area of ​​attraction between the iron support plates 21 and the iron block 14, thereby increasing the attraction force.

[0026] In one embodiment of this utility model, such as Figures 1-3 As shown, a limiting ring 3 is fitted on the outer wall of the clamping arm 2. The limiting ring 3 includes a metal ring 31, with openings at both ends of the metal ring 31. There are three sets of metal rings 31. A set of rubber sliders 32 is slidably connected between two adjacent sets of metal rings 31 through the openings. The three sets of metal rings 31 correspond to the three sets of guard plates 22. The outer wall of the guard plate 22 fits against the inner wall of the metal ring 31. The limiting ring 3 plays a limiting role on the outer side of the clamping arm 2.

[0027] Specifically, after the electromagnet 13 is de-energized, the iron block 14 loses its magnetic attraction to the iron support plate 21. The iron support plate 21 and the guard plate 22 rotate outward under the action of the counterweight 23. After rotating to a certain angle, the metal ring 31 can support the guard plate 22, preventing the guard plate 22 from rotating excessively. This prevents the iron support plate 21 from being unable to attract the iron block 14 when the electromagnet 13 is energized next time, as the distance between the iron support plate 21 and the iron block 14 is too far. The rubber slider 32 plays a certain buffering role, preventing the guard plate 22 from colliding and being damaged when it comes into contact with the metal ring 31. At the same time, since the counterweight 23 is designed to bulge outward, it can always be ensured that the counterweight 23 is below the metal ring 31. Even when the counterweight 23 is lifted upward while the fixed insert teeth are inserted, the limiting ring 3 will not disengage from the clamping arm 2.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working Principle: When in use, energizing the electromagnet 13 generates a magnetic field, which in turn magnetizes the iron block 14. Since the iron support plate 21 is made of iron, it is attracted to the magnetic iron block 14. Under the action of the rotating shaft, the three sets of iron support plates 21 rotate toward the iron block 14. At this time, the insert teeth are placed in the center of the clamping arm 2. As the iron support plates 21 rotate, the three sets of guard plates 22 are simultaneously rotated and lifted. Because the inner wall of the guard plate 22 fits against the edge of the insert teeth, and under the action of magnetic force, the iron support plate 21 always rotates toward the iron block 14, it can cooperate with insert teeth of different sizes. If the diameter of the insert teeth is large, the angle at which the guard plate 22 is lifted is smaller, so as to fit and fix it against the edge of the insert teeth; if the diameter of the insert teeth is small, the angle at which the guard plate 22 is lifted is larger. When the iron support plate 21 is completely adsorbed onto the surface of the iron block 14, the lifting angle of the guard plate 22 is at its maximum, thereby achieving a clamping and fixing of the edge of the insert teeth.

[0030] When the electromagnet 13 is de-energized, the iron block 14 loses its magnetic attraction to the iron support plate 21. At this time, the iron support plate 21 and the guard plate 22 rotate outward under the action of the counterweight 23. After rotating to a certain angle, the metal ring 31 can support the guard plate 22, preventing the guard plate 22 from rotating excessively. This is to prevent the iron support plate 21 from being unable to attract the iron block 14 due to the distance when the electromagnet 13 is energized next time. The rubber slider 32 plays a certain buffering role, preventing the guard plate 22 from colliding and being damaged when it comes into contact with the metal ring 31. At the same time, because the counterweight 23 is designed to bulge outward, it can always be ensured that the counterweight 23 is below the metal ring 31. Even when the counterweight 23 is lifted upward while the fixed inner teeth are inserted, the limiting ring 3 will not disengage from the clamping arm 2.
