Description

Technical Field

[0001] This utility model relates to the field of feeding technology, and in particular to a pipe feeding mechanism for a honing machine. Background Technology

[0002] A horizontal honing machine is a specialized piece of equipment with a "horizontal layout" as its core structure, focusing on the precision honing of the inner holes of parts. It is widely used in high-end manufacturing fields such as automobiles, construction machinery, hydraulics, and aerospace. It is a key piece of equipment for achieving synergistic improvement in the dimensional accuracy, shape accuracy, and surface quality of inner holes, and is especially suitable for machining deep holes and inner holes with large length-to-diameter ratios.

[0003] The entry of the pipeline into the horizontal honing machine is a key link connecting the workpiece and the honing spindle. Its operating status directly affects the processing accuracy and production efficiency. However, due to the low coefficient of friction, aluminum alloy pipelines are prone to slippage during transportation, which can cause momentary interruptions or fluctuations in the feed speed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art and to propose a pipe feeding mechanism for honing machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipe feeding mechanism for a honing machine, comprising a base, a spacing adjustment mechanism fixedly connected to the upper side of the base, and a lower conveying mechanism and an upper conveying mechanism fixedly connected to one side of the spacing adjustment mechanism, which are parallel to each other and have the same structural composition. The lower conveying mechanism and the upper conveying mechanism are connected to a transmission line for transmission. The lower conveying mechanism includes a chain conveyor belt, connecting strips, and rubber blocks. Multiple sets of connecting strip arrays are fixedly connected to the outside of the two chains of the chain conveyor belt. The connecting strips are perpendicular to the two chains. The middle of the rubber block is provided with an arc groove for accommodating the pipe. A set of connecting strips and a set of rubber blocks are fixedly connected by bolts. Multiple sets of rubber blocks are distributed along the track of the chain conveyor belt.

[0006] Preferably, the spacing adjustment mechanism includes a threaded column, a first connecting seat, a second connecting seat, a vertical frame, and a smooth column. The lower conveying mechanism and the upper conveying mechanism are slidably connected to the smooth column, the first connecting seat is fixedly connected to the middle of one side of the upper conveying mechanism, and the second connecting seat is fixedly connected to the middle of one side of the lower conveying mechanism.

[0007] Preferably, the second connecting seat is rotatably connected to the lower part of the outer ring surface of the threaded column, the first connecting seat is threadedly connected to the thread on the outer ring surface of the threaded column, and the first connecting seat and the smooth column are rotatably connected to the vertical frame respectively.

[0008] Preferably, the transmission line includes a geared motor, a first chain and sprocket assembly, a first gear, a second gear, a second chain and sprocket assembly, a tension wheel, and a third chain and sprocket assembly. The third chain and sprocket assembly is driven to the end of the upper conveying mechanism, the second chain and sprocket assembly is driven to the end of the lower conveying mechanism, the tension wheel is driven to the chain of the third chain and sprocket assembly, and the tension wheel is fixedly connected to the outside of the vertical frame.

[0009] Preferably, the other end of the third chain sprocket assembly is connected to the shaft of the second gear, and the other end of the second chain sprocket assembly is connected to the shaft of the first gear. The first gear and the second gear mesh with each other and are both rotatably mounted inside the vertical frame.

[0010] Preferably, the first chain and sprocket assembly is driven to the other end of the shaft of the first gear, and the other end of the first gear is driven to the output shaft of the geared motor, which is fixedly installed inside the base.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, a speed-reducing and torque-increasing power is provided by a geared motor. Through the meshing transmission of the first chain sprocket assembly, the first gear, and the second gear, the second and third chain sprocket assemblies are synchronously driven to rotate, causing the lower conveying mechanism to rotate in opposite directions to the upper conveying mechanism. Because both have the same structure, the power transmission is symmetrical and stable, preventing conveying deviation. Multiple sets of rubber blocks with arc grooves at the conveying end can adapt to the pipe shape and effectively clamp it, cyclically applying horizontal force to ensure continuous and stable pipe movement, meeting the feeding requirements of the honing machine. Simultaneously, the rubber blocks and connecting strips are fixed with bolts for easy disassembly and replacement; the tensioning wheel can also maintain the chain tension of the third chain sprocket assembly during spacing adjustment, preventing power interruption, resulting in strong overall practicality.

[0013] 2. In this invention, by rotating the threaded column and utilizing the rotational connection of the second connecting seat and the threaded connection of the first connecting seat, the rotation can be converted into a vertical moving force for the upper conveying mechanism, causing it to move along the smooth column. This allows for easy adjustment of the distance between the upper and lower conveying mechanisms, adapting to pipes of different diameters and overcoming the limitations of a single distance fit. The smooth column guides the movement of the conveying mechanism, ensuring that the vertical movement of the upper conveying mechanism does not deviate and preventing unstable pipe clamping. The vertical frame provides stable support for the rotation of the threaded column and the movement of the conveying mechanism, enhancing adjustment stability. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 5As shown, this utility model provides a pipe feeding mechanism for a honing machine, including a base 1. A spacing adjustment mechanism 4 is fixedly connected to the upper side of the base 1. A lower conveying mechanism 2 and an upper conveying mechanism 3, which are parallel to each other and have the same structure, are fixedly connected to one side of the spacing adjustment mechanism 4. The lower conveying mechanism 2 and the upper conveying mechanism 3 are connected by a transmission line 5. The lower conveying mechanism 2 includes a chain conveyor belt 21, connecting bars 22 and rubber blocks 23. Multiple sets of connecting bars 22 are arrayed and fixedly connected to the outside of the two chains of the chain conveyor belt 21. The connecting bars 22 are perpendicular to the two chains. The middle of the rubber block 23 is provided with an arc groove to accommodate the pipe. A set of connecting bars 22 and a set of rubber blocks 23 are fixedly connected by bolts. Multiple sets of rubber blocks 23 are distributed along the track of the chain conveyor belt 21. The transmission line 5 includes a geared motor 51, a first chain and sprocket assembly 52, a first gear 53, a second gear 54, a second chain and sprocket assembly 55, a tension wheel 56, and a third chain and sprocket assembly 57. The third chain and sprocket assembly 57 is drivenly connected to the end of the upper conveying mechanism 3, the second chain and sprocket assembly 55 is drivenly connected to the end of the lower conveying mechanism 2, and the tension wheel 56 is drivenly connected to the chain of the third chain and sprocket assembly 57 and is fixedly connected to the outside of the vertical frame 44. The other end of the third chain and sprocket assembly 57 is drivenly connected to the shaft of the second gear 54, and the other end of the second chain and sprocket assembly 55 is drivenly connected to the shaft of the first gear 53. The first gear 53 and the second gear 54 mesh with each other and are both rotatably mounted inside the vertical frame 44. The first chain and sprocket assembly 52 is drivenly connected to the other end of the shaft of the first gear 53, and the other end of the first gear 53 is drivenly connected to the output shaft of the geared motor 51. The geared motor 51 is fixedly mounted inside the base 1.

[0023] The specific settings and functions of this embodiment are described below: The speed-reducing motor 51 provides power for speed reduction and torque increase, which is transmitted to the first gear 53 via the first chain sprocket assembly 52. ​​Then, through the meshing of the first gear 53 and the second gear 54, the second chain sprocket assembly 55 and the third chain sprocket assembly 57 can be driven to operate synchronously, thereby enabling the lower conveying mechanism 2 and the upper conveying mechanism 3 to rotate in opposite directions. Since the two have the same structure, the symmetry and stability of power transmission can be ensured. In the lower conveying mechanism 2, multiple sets of rubber blocks 23 with arc grooves are fixed to the chain conveyor belt 21 by connecting strips 22. The arc grooves can adapt to the shape of the pipe and form an effective clamp. When the upper and lower conveying mechanisms operate in opposite directions, the multiple sets of rubber blocks 23 can cyclically apply horizontal force to the pipe, ensuring that the pipe moves stably between the two and meeting the continuous feeding requirements of the honing machine. At the same time, the rubber blocks 23 are fixed to the connecting strips 22 by bolts, which makes it easy to loosen the bolts periodically to remove and replace the rubber blocks 23, improving the flexibility of the mechanism.

[0024] Example 2: Figure 1 - Figure 4As shown, the spacing adjustment mechanism 4 includes a threaded column 41, a first connecting seat 42, a second connecting seat 43, a vertical frame 44, and a smooth column 45. The lower conveying mechanism 2 and the upper conveying mechanism 3 are slidably connected to the smooth column 45. The first connecting seat 42 is fixedly connected to the middle of one side of the upper conveying mechanism 3, and the second connecting seat 43 is fixedly connected to the middle of one side of the lower conveying mechanism 2. The second connecting seat 43 is rotatably connected to the lower part of the outer ring surface of the threaded column 41. The first connecting seat 42 is threadedly connected to the thread on the outer ring surface of the threaded column 41. The first connecting seat 42 and the smooth column 45 are rotatably connected to the vertical frame 44.

[0025] The overall effect of this embodiment is that by rotating the threaded column 41, and utilizing the rotational connection between the second connecting seat 43 and the threaded column 41, and the threaded connection between the first connecting seat 42 and the threaded column 41, the rotation of the threaded column 41 can be converted into a vertical moving force of the first connecting seat 42. This, in turn, drives the upper conveying mechanism 3 to move vertically along the length direction of the smooth column 45, thereby adjusting the distance between the upper conveying mechanism 3 and the lower conveying mechanism 2. This allows for the adaptation to pipes of different diameters, solving the problem that a single spacing mechanism cannot meet the diverse feeding needs of pipes. The sliding connection between the smooth column 45 and the upper and lower conveying mechanisms guides the movement direction of the upper and lower conveying mechanisms, ensuring... The upper conveying mechanism 3 remains vertical during movement to prevent deviation and instability in pipe clamping. The rotatable connection between the vertical frame 44, the first connecting seat 42, and the smooth column 45 provides stable support for the rotation of the threaded column 41 and the movement of the upper and lower conveying mechanisms, enhancing the structural stability during the spacing adjustment process. At the same time, the cooperation between this spacing adjustment structure and the tension wheel 56 in the subsequent transmission line 5 ensures that the chain of the third chain sprocket assembly 57 is kept taut after the spacing is adjusted, ensuring that the power transmission is not affected by the spacing change. Overall, it achieves the effect of precise spacing adjustment, adaptability to various pipes, and stable and reliable adjustment process.

[0026] The operating method and working principle of this device are as follows: Install the mechanism at the feed position of the horizontal honing machine. By rotating the handle, the threaded column 41 rotates in the second connecting seat 43 and is transmitted in the first connecting seat 42, giving the first connecting seat 42 a downward force. This drives the upper conveying mechanism 3 to move vertically downwards along the length of the smooth column 45, reducing the distance between the upper conveying mechanism 3 and the lower conveying mechanism 2 to accommodate pipes of different diameters. Next, adjust the tension wheel 56 so that the chain in the third chain sprocket assembly 57 is always in a normally taut state. After adjusting to the appropriate distance, start the reduction motor 51. The reduced speed and increased torque of the reduction motor 51 drive the first chain sprocket assembly 52 to rotate. The first chain sprocket assembly 52 drives the first gear 53 to rotate, thereby meshing with the second gear 54. When the first gear 53 rotates, its shaft drives the second chain sprocket assembly 55 to rotate. The power of component 55 is transmitted to the lower conveying mechanism 2. When the second gear 54 rotates, its shaft drives the third chain sprocket assembly 57 to rotate. The power of the third chain sprocket assembly 57 is transmitted to the upper conveying mechanism 3. Since the first gear 53 and the second gear 54 mesh, the lower conveying mechanism 2 and the upper conveying mechanism 3 rotate in opposite directions. The two mechanisms have the same structure. The two chains of the chain conveyor belt 21 in both the lower conveying mechanism 2 and the upper conveying mechanism 3 rotate, driving the multiple sets of connecting strips 22 and multiple sets of rubber blocks 23 to move along the track of the chain. When the arc grooves of one set of rubber blocks 23 in the lower conveying mechanism 2 and the upper conveying mechanism 3 are stuck on both sides of the pipe and are in a nearly vertical state, a horizontal force is applied to the pipe. The multiple sets of rubber blocks 23 repeat this process, so that the pipe moves stably between the lower conveying mechanism 2 and the upper conveying mechanism 3. The rubber blocks 23 can be disassembled and replaced by periodically loosening the screws, which is highly flexible.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
