Description

Technical Field

[0001] This utility model relates to the field of machining auxiliary devices, specifically a metal trunnion mounting auxiliary tooling. Background Technology

[0002] Both ferrous and non-ferrous metallurgical enterprises generate large quantities of high-temperature molten slag. Most enterprises use slag bags, also known as slag pots, to contain and process this slag. Metal trunnions are typically attached to both sides of the slag bag, bearing the weight of the entire bag and being one of its most frequently used components. Because the slag bag needs frequent movement and tilting during the metallurgical process, the strength and durability of the trunnions are crucial. They must be able to withstand the total weight of the slag bag and its internal slag, ensuring no deformation or damage occurs during operation. Currently, the metal trunnions for slag bags are usually installed first on trunnion seats, which are then welded to the sides of the bag. However, the installation process currently involves manually using hoisting machinery to transport the trunnions to the seats, aligning them with the pre-drilled holes, and hammering them into the seats for fixation – a very labor-intensive process. Therefore, there is a need to develop a labor-saving auxiliary tooling for installing metal trunnions onto trunnion seats. Utility Model Content

[0003] To address the above technical problems, this utility model provides a metal trunnion installation auxiliary tooling that can save manpower and facilitate the installation of metal trunnions on trunnion seats, thereby solving the problem of time-consuming and labor-intensive installation of metal trunnions.

[0004] To solve the above-mentioned technical problems, the present invention provides a metal trunnion installation auxiliary tooling, comprising a base, a heater fixedly connected to the bottom of the base, and a through hole corresponding to the position of the heater on the top of the base. A bidirectional screw is rotatably connected to one side of the base, and a slide rod is fixedly connected to the other side. One end of the bidirectional screw passes through the base and is fixedly connected to the output shaft of a motor. Limiting plates are symmetrically threaded on both sides of the bidirectional screw. The limiting plates are slidably connected to the slide rod. A strip groove is formed on the upper part of the limiting plates through the top of the base. A bracket is fixedly connected to the top of the base, and a hydraulic cylinder is fixedly connected to the upper end of the bracket. The output end of the hydraulic cylinder passes downward through the bracket.

[0005] Furthermore, an installation plate is fixedly connected to the inner side of the limiting plate, a slider is connected to the installation plate through a guide assembly, a telescopic rod is fixedly connected to the inner side of the slider, and an arc-shaped clamp is fixedly connected to the output end of the telescopic rod.

[0006] Furthermore, the guiding assembly includes a guide sleeve and a guide rod. The guide sleeve is fixedly connected to the upper end of the mounting plate, and the guide rod is fixedly connected to the lower end of the slider. The lower end of the guide rod is slidably connected to the guide sleeve. A spring is sleeved on the outside of the guide sleeve and the guide rod. The lower end of the spring is fixedly connected to the mounting plate, and the upper end is fixedly connected to the slider.

[0007] Furthermore, a groove is provided on the upper part of the limiting plate, and one end of the slider is slidably connected to the groove.

[0008] Furthermore, a pressure plate is fixedly connected to the output end of the hydraulic cylinder.

[0009] Furthermore, the heater is a gas stove, and a gas pipe extending through the base to the outside of the gas stove is connected to one side of the gas stove.

[0010] Furthermore, the base has several ventilation holes on its side.

[0011] This utility model has the following advantages compared with the prior art:

[0012] 1. This utility model, by setting a bidirectional screw and slide bar in the base and matching it with a limiting plate, can achieve limiting clamping of the trunnion seat, which is convenient for fixing the trunnion assembly; by setting a heater in the base, the trunnion seat can be heated, making full use of thermal expansion to increase its diameter, which is convenient for installing the metal trunnion on the trunnion seat; by setting a hydraulic cylinder and a pressure plate, the metal trunnion can be pressed down, which is convenient for the metal trunnion to be embedded into the trunnion seat, saving manpower and improving work efficiency.

[0013] 2. By setting a telescopic rod and an arc-shaped clamping plate, this utility model can easily achieve the clamping and fixing of the metal trunnion. At the same time, the setting of the slider and guide assembly can facilitate the synchronous downward movement of the telescopic rod and the arc-shaped clamping plate during the metal trunnion insertion process, ensuring the stability of the metal trunnion insertion process and improving the installation quality of the metal trunnion.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1 , 2 A metal trunnion installation auxiliary tooling shown in Figure 3 includes a base 1, which is a hollow structure. A heater 2 is fixedly connected to the bottom of the base 1 by bolts, and a through hole is opened at the top corresponding to the position of the heater 2. A bidirectional screw 3 is rotatably connected to one side of the base 1 by a bearing, and a slide rod 5 is fixedly connected to the other side. The bidirectional screw 3 has symmetrical threads in opposite directions on both sides from the middle position. One end of the bidirectional screw 3 passes through the base 1 and is fixedly connected to the output shaft of a motor 4 fixed to the outside of the base 1 by a motor seat and bolts. Limiting plates 6 are symmetrically threaded on both sides of the bidirectional screw 3. The other side of the limiting plate 6 is slidably connected to the slide rod 5. The upper part of the limiting plate 6 passes through the top of the base 1 and has a strip groove that is slidably connected to it. A bracket 7 is fixedly connected to the top of the base 1. A hydraulic cylinder 8 is fixedly connected to the upper end of the bracket 7 by a connecting frame and bolts. The output end of the hydraulic cylinder 8 is set downward through the bracket 7.

[0020] It should be noted that in this embodiment, when installing the metal trunnion, the trunnion seat 15 is placed on the upper surface of the base 1, and its center position is on the same vertical line as the through hole of the base 1 and the center point of the heater 2; the trunnion seat has a hole diameter smaller than that on the base 1.

[0021] To facilitate clamping of the metal trunnion and avoid manual support by workers, while ensuring that the arc-shaped clamping plate 14 moves downwards during installation, a mounting plate 10 is fixedly connected to the inner side of the limiting plate 6. A guide assembly 11 is fixedly connected to the mounting plate 10, and a slider 12 is connected to the upper end of the guide assembly 11. A telescopic rod 13 is fixedly connected to the inner side of the slider 12, and the arc-shaped clamping plate 14 is fixedly connected to the output end of the telescopic rod 13. It should be noted that in this embodiment, two telescopic rods 13 are fixedly connected to the inner side of each slider 12, and one arc-shaped clamping plate 14 is fixedly connected to the output end of the two telescopic rods 13. For ease of use and to simplify the structure, the telescopic rod 13 is an electric telescopic rod, but it can also be a hydraulic or pneumatic telescopic rod.

[0022] To facilitate the vertical downward installation of the metal trunnion and prevent it from shifting during installation, the guide assembly 11 includes a guide sleeve 1101 and a guide rod 1102. The guide sleeve 1101 is fixedly connected to the upper end of the mounting plate 10, and the guide rod 1102 is fixedly connected to the lower end of the slider 12. The lower end of the guide rod 1102 is slidably connected to the guide sleeve 1101. A spring 1103 is sleeved on the outside of the guide sleeve 1101 and the guide rod 1102. The lower end of the spring 1103 is fixedly connected to the mounting plate 10, and the upper end is fixedly connected to the slider 12.

[0023] To further improve the stability of the arc-shaped clamping plate 14 during downward movement, a sliding groove is provided on the upper part of the limiting plate 6, and the outer side of the slider 12 is slidably connected to the sliding groove.

[0024] To increase the contact area with the upper end of the metal trunnion, the output end of the hydraulic cylinder 8 is fixedly connected to a pressure plate 9 by bolts.

[0025] To ensure good heating effect, thermal expansion is fully utilized to increase the diameter of the trunnion seat 15, so that the metal trunnion can be installed on the trunnion seat 15 with less effort. The heater 2 is a gas stove, and a gas pipe 16 is connected to one side of the gas stove, which extends through the base 1 to its outer side. The gas pipe 16 is connected to the gas storage bottle.

[0026] To facilitate ventilation and air intake for combustion, several ventilation holes 17 are provided on the side of the base 1.

[0027] It should be noted that in this embodiment, an anti-slip protective layer is fixedly connected to the inner side of the arc-shaped clamp 14. The anti-slip protective layer is made of rubber. At the same time, the device is equipped with a pressure supply component that matches the hydraulic cylinder 8. The gas stove is an existing device, and its specific structure will not be described in detail in this article.

[0028] The working process of this embodiment is as follows:

[0029] When installing the metal trunnion, first place the trunnion seat 15 in the middle of the upper surface of the base 1, control the motor 4 to rotate, the motor 4 drives the bidirectional screw 3 to rotate, and then drives the limiting plate 6 to move relative to it. At the same time, the limiting plate 6 slides on the slide rod 5. After the limiting plate 6 clamps and limits the trunnion seat 15, the motor 4 is turned off. Start the heater 2 to heat the trunnion seat 15. Then, use the transfer device to place the metal trunnion on the trunnion seat 15, adjust the position of the metal trunnion so that it is aligned with the hole opened on the trunnion seat 15, then control the extension rod 13 to extend, so that the arc-shaped clamping plate 14 clamps and fixes the metal trunnion. Start the hydraulic cylinder 8 to extend. The length of the platen 9 allows it to contact the upper surface of the metal trunnion and press down continuously, causing the lower end of the trunnion to be inserted into the hole of the trunnion seat 15. When the trunnion is inserted, the slider 12 slides downward within the limiting plate 6, while the guide rod 1102 is inserted downward into the guide sleeve 1101, thereby driving the arc-shaped clamping plate 14 to move downward steadily with the metal trunnion. After the metal trunnion is inserted into the trunnion seat 15, the control motor 4 rotates in the opposite direction to make the limiting plate 6 leave the trunnion seat 15, and at the same time, the arc-shaped clamping plate 14 leaves the metal trunnion. Under the action of the spring 1103, the slider 12 drives the telescopic rod 13 and the arc-shaped clamping plate 14 to return to their original positions. The trunnion seat 15 with the metal trunnion installed can then be transferred using a transfer device.
