Description

Technical Field

[0001] This utility model relates to the field of ion nitriding furnace technology, specifically to a safety positioning and guiding device for an ion nitriding furnace cover. Background Technology

[0002] In the ion nitriding process, the installation of the furnace lid and furnace base is a crucial step. As an important piece of equipment for nitriding metal surfaces, the ion nitriding furnace lid needs to be accurately and stably installed on the furnace base to ensure the formation of a suitable sealed space and process environment inside the furnace, thereby guaranteeing the quality and effectiveness of the nitriding treatment.

[0003] In traditional furnace cover installation, operators rely primarily on experience and visual inspection to adjust the cover's position, making it difficult to ensure precise concentricity between the cover and the furnace base. This leads to frequent cover misalignment during installation, resulting in uneven sealing between the cover and the base, affecting the gas environment inside the furnace, reducing the quality of the nitriding process, and potentially causing it to fail. Each cover installation requires significant time for repeated adjustments and calibrations. Operators must constantly move the cover up and down, observe its position, and manually fine-tune it, which not only increases labor intensity but also significantly extends equipment downtime and reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a safety positioning and guiding device for an ion nitriding furnace cover, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety positioning and guiding device for an ion nitriding furnace cover, comprising a furnace base, and further comprising: A furnace cover is installed on the upper part of the furnace base, and a base is installed on the outside of the furnace base. A positioning component for supporting and positioning the furnace cover is installed on the base. An adjustment component mounted on a base to adjust the positioning assembly to the appropriate position of the furnace cover.

[0006] Preferably, the positioning component includes three sets of vertical rods rotatably mounted on the base in annular shape, with support rods fixedly mounted on the vertical rods, and several sets of rollers rotatably mounted on the support rods. Limit grooves are provided on all three sets of vertical rods.

[0007] Preferably, the adjustment assembly includes two sets of symmetrically mounted fixing seats fixedly installed on the base, a hydraulic rod fixedly installed on the top of the fixing seat, and a conical ring fixedly installed on the top of the piston rod of the hydraulic rod.

[0008] Preferably, three sets of limiting rods are fixedly installed on the conical ring.

[0009] Preferably, the base is made of metal material, with an opening on one side, and mounting seats are welded to both sides of the opening.

[0010] Preferably, a reinforcing rod is welded to the vertical rod, and the other end of the reinforcing rod is welded to the support rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the adjusting component uses a hydraulic rod to push the conical ring up and down. When the conical ring moves upward, it can simultaneously retract the three vertical rods. The positioning component uses the three synchronously retracting vertical rods and the rollers on the support rods to move the furnace cover to a position concentric with the base and furnace seat. The rollers limit the furnace cover, making it move vertically downward, effectively preventing the furnace cover from shifting during installation and ensuring installation accuracy. The limiting rod installed on the conical ring and the limiting groove on the vertical rod cooperate with each other. When the conical ring moves upward and drives the vertical rods to retract, they are positioned, making the vertical rod retraction process more stable and preventing the vertical rods from shifting left and right, further ensuring the positioning effect of the furnace cover.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4As shown, an ion nitriding furnace cover safety positioning and guiding device includes a furnace base 1, and further includes: a furnace cover 2 installed on the upper part of the furnace base 1, a base 3 installed on the outer side of the furnace base 1, a positioning component 4 for supporting and positioning the furnace cover 2 installed on the base 3; and an adjustment component 5 installed on the base 3 to adjust the positioning component 4 to a suitable position of the furnace cover 2; both the positioning component 4 and the adjustment component 5 are installed on the outer side of the furnace base 1 through the base 3, and the base 3 is detachably installed on the outer side of the furnace base 1 and can be removed when not in use.

[0016] When installing the furnace cover 2, the positioning component 4 and the adjusting component 5 are fixed to the furnace base 1 via the base 3. Then, the furnace cover 2 is lifted by the hoisting equipment and the lifting ring on the top of the furnace cover 2, so that the furnace cover 2 moves towards the furnace base 1. After the furnace cover 2 moves to the upper part of the furnace base 1, the furnace cover 2 is lowered. When the furnace cover 2 moves to a certain height and enters the range of the positioning component 4, the position of the positioning component 4 is adjusted by the adjusting component 5 to position the furnace cover 2 so that it is installed vertically downward on the furnace base 1, so as to avoid the furnace cover 2 from shifting during the installation process and affecting the installation effect.

[0017] Based on the above implementation plan, and referring to Figure 3 The positioning component 4 includes three sets of vertical rods 41 that are rotatably mounted on the base 3 in annular shape. Support rods 42 are fixedly mounted on the vertical rods 41, and several sets of rollers 43 are rotatably mounted on the support rods 42. Limiting grooves 7 are provided on each of the three sets of vertical rods 41. Reinforcing rods 9 are welded to the vertical rods 41, and the other end of the reinforcing rods 9 is welded to the support rods 42. The three vertical rods 41 are rotatably mounted on the base 3 through a rotating shaft. The support rods 42 are welded to the inner side of the vertical rods 41, and the rollers 43 are rotatably mounted inside them.

[0018] After the furnace cover 2 moves down and enters the range of the three vertical rods 41, the three vertical rods 41 retract inward synchronously, moving the rollers 43 on the support rods 42 to contact the furnace cover 2. Since the three vertical rods 41 move synchronously, the furnace cover 2 will be moved to a position concentric with the base 3 and the furnace seat 1. The rollers 43 limit the furnace cover 2, so that the furnace cover 2 moves vertically downward without any deviation.

[0019] Based on the above implementation scheme, the adjustment component 5 includes two sets of symmetrically installed fixed seats 51 fixedly installed on the base 3. A hydraulic rod 52 is fixedly installed on the top of the fixed seat 51, and a conical ring 53 is fixedly installed on the top of the piston rod of the hydraulic rod 52. The two fixed seats 51 are symmetrically welded to both sides of the base 3, and a hydraulic rod 52 is fixedly installed on the top of each fixed seat 51. The small opening of the conical ring 53 faces downward.

[0020] When the adjustment component 5 is working, the hydraulic rod 52 is activated, and the hydraulic rod 52 pushes the conical ring 53 up and down. When the conical ring 53 moves up, it simultaneously retracts the three vertical rods 41 to position the furnace cover 2.

[0021] Based on the above implementation scheme, three sets of limiting rods 6 are fixedly installed on the conical ring 53; the positions of the limiting rods 6 and the positions of the limiting grooves 7 on the vertical rod 41 correspond to each other, and the limiting rods 6 slide inside the limiting grooves 7.

[0022] When the conical ring 53 moves upward, it drives the limiting rod 6 to slide in the limiting groove 7. The limiting rod 6 and the limiting groove 7 are used to position the conical ring 53 and the vertical rod 41, making the vertical rod 41 more stable when it is retracted, and preventing the vertical rod 41 from shifting to the left or right and affecting the positioning effect of the furnace cover 2.

[0023] Based on the above implementation scheme, the base 3 is made of metal material, with an opening on one side, and mounting seats 8 are welded on both sides of the opening. The base 3 made of metal material has a certain degree of elasticity, and the opening can be pried open and snapped onto the outside of the furnace base 1. Fastening bolts are installed inside the mounting seats 8.

[0024] When installing the base 3, open the opening and snap it onto the outside of the furnace base 1. Then, install the bolts inside the mounting base 8 and tighten the mounting base 8 with the bolts to snap the base 3 onto the furnace base 1.

[0025] It should be noted that the hydraulic rod 52 in this solution is electrically connected to the control terminal via a wire. The control terminal can be set as a PLC programmable logic controller to control the above-mentioned electrical equipment to work. The above should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can adopt conventional choices in the field. This technical solution will not be further elaborated in detail.
