Description

Technical Field

[0001] This utility model belongs to the field of carburizing cylindrical roller machining technology, and in particular relates to a support device for carburizing cylindrical roller machining. Background Technology

[0002] As a core component of precision mechanical parts such as bearings, carburized cylindrical rollers directly affect the service life and operating accuracy of bearings due to their surface hardness, wear resistance, and core toughness. During the carburizing process, the rollers need to maintain a stable posture in a high-temperature carburizing atmosphere to ensure that the carburized layer on the outer surface is uniform and reaches the required depth. Therefore, the performance of the support device is one of the key factors that determine the processing quality.

[0003] Existing carburizing cylindrical rollers are mostly used in low-speed, heavy-duty machinery. During processing, they are simply supported and then processed. The carburizing cylindrical rollers are placed only by the grooves or lifting structures of the support device, and the rollers cannot maintain a fixed posture. Under the impact of high-temperature airflow and mechanical transmission vibration in the carburizing furnace, they are prone to rolling and displacement, resulting in poor processing stability and seriously affecting production efficiency. Therefore, a support device for processing carburizing cylindrical rollers is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a support device for processing carburized cylindrical rollers. By setting up a clamping mechanism, specifically by starting two motors to drive a turntable to rotate, and by having a sliding rod slide along a wedge-shaped groove, the rotation of the turntable causes the sliding rod to move along a sliding track, driving several clamping rods and clamping plates to move closer together, thereby clamping the surface of the carburized cylindrical roller and stably fixing it in a preset position. This ensures the stability of the processing, the uniformity of the carburized layer, and improves product quality. It solves the problem that existing carburized cylindrical rollers are mostly used in low-speed, heavy-duty machinery, and during processing, they are only supported and then processed. The rollers are placed solely by the grooves or lifting structures of the support device, and cannot maintain a fixed posture. Under the impact of high-temperature airflow and mechanical vibration in the carburizing furnace, the rollers are prone to rolling and shifting, resulting in poor processing stability and seriously affecting production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a support device for machining carburized cylindrical rollers, comprising a base, with support legs installed at each of the four corners of the base bottom, and a carburized cylindrical roller disposed on the top of the base, and further comprising: A clamping mechanism is disposed on the top of the base and is used to clamp carburized cylindrical rollers; An adjustment mechanism is provided at the bottom of the clamping mechanism, and the adjustment mechanism is used to adjust the clamping mechanism; Furthermore, the clamping mechanism includes a clamping assembly disposed on the top of the base. The clamping assembly is used to fix the carburized cylindrical roller. The clamping assembly includes two fixing plates, each of which has several sliding grooves. The several sliding grooves on the fixing plates provide precise sliding guidance for the slide rod, enabling the slide rod to move stably along a preset trajectory, thereby driving the clamping rod and the clamping plate to complete the clamping action of the carburized cylindrical roller.

[0006] Furthermore, the clamping mechanism includes support components, each of which is mounted on two fixed plates and is used to support the clamping components.

[0007] Furthermore, each of the several sliding grooves is slidably connected with a sliding rod, and each of the several sliding rods is equipped with a clamping rod on one side that is close to each other. Each of the several clamping rods is equipped with a clamping plate on its outer surface. Among them, several of the sliding grooves are wedge-shaped, and several of the sliding rods are arranged in groups of six, with a total of two groups.

[0008] Furthermore, the support assembly has two protective shells, which are respectively located on the side of the two fixed plates that are far apart from each other. Motor brackets are installed on the side of the two protective shells that are far apart from each other, and motors are installed inside the two motor brackets. The internal connection configurations of the two protective shells are identical.

[0009] Furthermore, the output ends of both motors are fixedly connected to turntables via couplings, and several sliding rails are installed on the side of the two turntables that are close to each other.

[0010] Furthermore, the adjustment mechanism includes a placement block disposed between two fixed plates, with rollers rotatably connected inside the placement block, and two sliding guide rails mounted on the top of the base; The two sliding guide rails are trapezoidal in shape, and the bottom of each of the two fixed plates is provided with a trapezoidal groove. Both fixed plates slide with the sliding guide rails through the trapezoidal grooves. The sliding guide rails are trapezoidal in shape and installed on the top of the base. They cooperate with the trapezoidal grooves on the bottom of the fixed plates to provide high-precision guidance and stable support for the sliding of the fixed plates. The trapezoidal structure has good anti-overturning performance and can effectively limit the lateral displacement of the fixed plates during the sliding process, ensuring that the two fixed plates always remain parallel when they are close to or far from each other.

[0011] Furthermore, two hollow sleeves are installed on both the left and right sides of the placement block. Each of the four hollow sleeves contains a spring, and a sliding rod is installed on the side of each spring that is furthest from the others. The spring is located inside the hollow sleeve, with one end connected to the sleeve and the other end connected to the sliding rod. When the fixing plate is pulled apart, the sliding rod stretches the spring, generating elastic potential energy due to deformation. After the fixing plate is released, the elastic potential energy of the spring is converted into driving force, pulling the sliding rod and the fixing plate closer together until the fixing plate abuts against both ends of the carburized cylindrical roller. Through the elastic action of the spring, it can automatically adapt to carburized cylindrical rollers of different lengths and provide a continuous and appropriate abutting force to the fixing plate, avoiding damage to the roller due to excessive abutting force or instability due to insufficient abutting force. The parts connected inside the four hollow sleeves are all the same. The four hollow sleeves are arranged in pairs, and the two pairs of hollow sleeves are symmetrically arranged with the placement block as the center.

[0012] This utility model has the following beneficial effects: This utility model, by setting up a clamping mechanism, specifically by starting two motors to drive the turntable to rotate, causes the slide rod to slide along the wedge-shaped groove. The rotation of the turntable causes the slide rod to move on the sliding track, driving several clamping rods and clamping plates to move closer to each other, thereby clamping the surface of the carburized cylindrical roller and fixing it stably in the preset position, ensuring the stability of the processing, ensuring the uniformity of the carburized layer, and improving the quality of the product.

[0013] This invention features an adjustment mechanism. Specifically, based on the length of the carburized cylindrical roller, the operator first pulls two fixed plates, causing them to move away from each other along a trapezoidal sliding guide. At this time, the fixed plates drive the sliding rod two to slide within the hollow sleeve, stretching the spring. Then, the roller is placed into the placement block, and the fixed plates are released. Under the action of the spring force, the two fixed plates automatically approach and press against both ends of the roller, thus quickly adapting to rollers of different specifications, reducing manual adjustment time, and improving the versatility of the device.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] 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 scope of protection of the present utility model.

[0019] Please see Figures 1-5 As shown, this utility model is a support device for processing carburized cylindrical rollers, including a base 1, with support legs 111 installed at each of the four corners of the bottom of the base 1, and a carburized cylindrical roller 112 provided on the top of the base 1, and also including: Clamping mechanism 2 is located on the top of base 1 and is used to clamp carburized cylindrical roller 112; Adjustment mechanism 3 is located at the bottom of clamping mechanism 2 and is used to adjust clamping mechanism 2; The clamping mechanism 2 includes a clamping assembly 21, which is disposed on the top of the base 1. The clamping assembly 21 is used to fix the carburized cylindrical roller 112. The clamping assembly 21 includes two fixing plates 211, and each fixing plate 211 has a plurality of sliding grooves 212.

[0020] The clamping mechanism 2 includes a support component 22, which is mounted on two fixed plates 211. The support component 22 is used to support the clamping component 21.

[0021] Each of the several sliding grooves 212 has a sliding rod 213 slidably connected inside. Each of the several sliding rods 213 has a clamping rod 214 installed on the side of each other that is close to each other. Each of the several clamping rods 214 has a clamping plate 215 installed on its outer surface. The several sliding grooves 212 are wedge-shaped. The several sliding rods 213 are in groups of six, and there are two groups in total.

[0022] The support assembly 22 has two protective shells 221, which are respectively located on the opposite sides of the two fixed plates 211. Motor brackets 222 are installed on the opposite sides of both protective shells 221, and motors 223 are installed inside each motor bracket 222. The internal connections of the two protective shells 221 are identical. Specifically, starting the two motors 223 drives the turntable 224 to rotate. As the slide rod 213 slides along the wedge-shaped groove 212, the rotation of the turntable 224 causes the slide rod 213 to move on the sliding track 225, driving several clamping rods 214 and clamping plates 215 to move closer together, thereby clamping the surface of the carburized cylindrical roller 112 and stabilizing it in the preset position. This ensures the stability of the processing, the uniformity of the carburized layer, and improves the quality of the product.

[0023] The output ends of the two motors 223 are fixedly connected to turntables 224 via couplings, and several sliding rails 225 are installed on the side of the two turntables 224 that are close to each other.

[0024] The adjustment mechanism 3 includes a placement block 311 disposed between two fixed plates 211. A roller 312 is rotatably connected inside the placement block 311. Two sliding guide rails 313 are installed on the top of the base 1. The two sliding guide rails 313 are trapezoidal. The bottom of the two fixed plates 211 is provided with trapezoidal grooves. The two fixed plates 211 slide with the sliding guide rails 313 through the trapezoidal grooves.

[0025] Two hollow sleeves 315 are installed on the left and right sides of the placement block 311. Each of the four hollow sleeves 315 contains a spring 316. A sliding rod 314 is installed on the side of each spring 316 that is furthest from the other. The parts connected inside the four hollow sleeves 315 are identical. The four hollow sleeves 315 are arranged in pairs, with two pairs of hollow sleeves 315 symmetrically positioned around the placement block 311. Specifically, based on the length of the carburized cylindrical roller 112, the operator first pulls the two fixed plates 211, causing them to move away from each other along the trapezoidal sliding guide rail 313. At this time, the fixed plates 211 drive the sliding rod 314 to slide within the hollow sleeve 315, stretching the spring 316. Then, the roller is placed into the placement block 311, and the fixed plates 211 are released. Under the elastic force of the spring 316, the two fixed plates 211 automatically move closer together and press against both ends of the roller, thus quickly adapting to rollers of different specifications, reducing manual adjustment time, and improving the versatility of the device.

[0026] A specific application of this embodiment is as follows: In use, the operator first determines the length of the carburized cylindrical roller 112. Once the length of the carburized cylindrical roller 112 is determined, the two fixed plates 211 are first pulled apart, causing them to move away from each other. At this time, the two fixed plates 211 will slide on the two sliding guide rails 313. The sliding guide rails 313 are trapezoidal, providing stable support for the fixed plates 211 and ensuring that the two fixed plates 211 can slide smoothly on the base 1. Since the two springs 316 are fixedly connected to the slide rod 314, Furthermore, the two sliding rods 314 are fixedly connected to the fixed plate 211, and simultaneously slidably connected to the hollow sleeve 315. Therefore, when the two fixed plates 211 move away from each other, they will cause the sliding rods 314 to slide. At this time, when the two sliding rods 314 move away from each other, they will stretch the spring 316. Then, the worker can hold the carburized cylindrical roller 112 and place it on the placement block 311. At this time, the worker can release the two fixed plates 211. Under the elastic action of the spring 316, the two fixed plates 211 will move closer to each other until they touch... The carburized cylindrical rollers 112 are abutted at both ends, reducing the time required for manual adjustment of different specifications of carburized cylindrical rollers 112. After adapting to different specifications of carburized cylindrical rollers 112, the user can then start two motors 223 to drive the turntable 224 to rotate. Since the slide rod 213 slides through the sliding rail 225, and the groove 212 is wedge-shaped, when the turntable 224 rotates, the sliding rail 225 will rotate accordingly. At this time, the slide rod 213 will slide on the sliding rail 225 under the action of the wedge shape of the groove. The motor 223... As the rotation continues, several clamping rods 214 will be driven to move closer to each other, which in turn will cause several clamping plates 215 to move closer to each other. At this time, under the movement of the clamping rods 214, the clamping plates 215 will clamp and fix the surface of the carburized cylindrical roller 112. Through stable clamping, the roller can be fixed in the preset position to prevent it from shaking or shifting, thereby improving product quality. When the carburized cylindrical roller 112 is fixed, the user can push the carburized cylindrical roller 112 by hand. At this time, the carburized cylindrical roller 112 will rotate through the roller 312 inside the placement block 311 for processing.
