Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and in particular to a simple structure machine tool for horizontal long-stroke honing. Background Technology

[0002] Horizontal honing lathe is a precision machining process, belonging to the honing process. It is mainly used for finishing and precision machining of the inner surface of hole-type parts, thereby improving the dimensional accuracy, shape accuracy and surface finish of the holes.

[0003] Because horizontal honing lathes are expensive to purchase, most factories modify existing lathes to perform honing when needed. This is mainly achieved by adding a honing head to the lathe's feed box, enabling the lathe to perform honing operations. When honing a workpiece, the operator simply aligns the honing head with the workpiece's inner hole.

[0004] However, most methods for modifying lathes on the market involve working on the lathe body itself. The honing head can only move within the travel range of the lathe body, resulting in a short travel distance. This makes it unsuitable for honing the inner holes of long and deep sleeve-type parts, leaving room for improvement. Utility Model Content

[0006] This utility model provides a simple structure machine tool for horizontal long-stroke honing, which adopts the following technical solution: A horizontal long-stroke honing machine tool with a simple structure includes a clamping lathe, a honing head, and a drive device for driving the honing head to move horizontally. It also includes a honing lathe for extending the clamping lathe and a honing connecting rod for extending the honing head. The honing lathe is connected to the clamping lathe. The honing connecting rod connects the honing head and the drive device. The drive device is horizontally slidably mounted on the honing lathe.

[0007] By adopting the above technical solution, a honing lathe is connected and set on the basis of the original clamping lathe, and a honing connecting rod with increased distance is installed on the honing head. The honing connecting rod is connected to the drive device, and the honing connecting rod is moved by the drive device, thereby increasing the honing stroke length of the lathe.

[0008] Optionally, the honing head includes a honing head housing, an oilstone circumferentially disposed in the honing head housing and radially retractable, and a top extension assembly telescopically installed inside the honing head housing and driving the oilstone to telescopically extend and retract; the top extension assembly passes through the honing connecting rod.

[0009] By adopting the above technical solution, the honing head has a honing head shell, an oilstone is placed on the honing head shell, and the oilstone is extended by the extension component, so as to facilitate the honing head to enter the inner hole and then process the inner hole. At the same time, the honing head can adapt to the processing of workpieces with different inner diameters.

[0010] Optionally, a universal joint for reducing the torque of the honing connecting rod is provided between the honing head housing and the honing connecting rod; the top extension assembly passes through the universal joint.

[0011] By adopting the above technical solution, a universal joint is set between the honing head housing and the honing connecting rod, and the top extension assembly passes through the universal joint. This reduces the torque on the honing connecting rod when the honing head is machining the inner hole, thereby improving the service life of the honing connecting rod.

[0012] Optionally, the driving device includes a drive plate slidably mounted on the top of the honing lathe, a lifting cylinder for driving the lifting assembly to lift the honing stone, and a motor assembly for driving the drive plate to move; both the lifting cylinder and the motor assembly are mounted on the drive plate.

[0013] By adopting the above technical solution, a drive plate is set on the honing lathe, a top extension cylinder is set on the drive plate, and a motor assembly is set on the drive plate. By setting the top extension cylinder and the motor assembly on the drive plate, the motor assembly can drive the drive plate and lift the honing stone by the top extension cylinder. In this way, the honing head can be moved by using the motor assembly and the top extension cylinder to lift the honing stone, thereby improving the honing efficiency.

[0014] Optionally, the motor assembly includes a geared motor mounted on the drive plate, a gear set connected to the geared motor, and a sprocket connected to the gear set; a chain is laid flat on the honing lathe, and the sprocket cooperates with the chain.

[0015] By adopting the above technical solution, the rotation of the geared motor drives the gear set to rotate, the gear set drives the sprocket to rotate, and the chain below cooperates to drive the drive plate to move, thereby improving the movement stability of the drive plate and making the honing more stable.

[0016] Optionally, the honing lathe is provided with a cantilever bracket on the side near the clamping lathe for supporting the honing connecting rod during the movement of the drive device; a wear-resistant copper sleeve is provided between the cantilever bracket and the honing connecting rod.

[0017] By adopting the above technical solution, an extension bracket is set between the honing lathe and the clamping lathe. The honing connecting rod is supported by the extension bracket, which improves the stability of the honing head and the honing connecting rod during movement. Furthermore, a wear-resistant copper sleeve is set between the honing connecting rod and the extension bracket, allowing the honing connecting rod to slide on the wear-resistant copper sleeve, thereby reducing the wear of the honing connecting rod.

[0018] Optionally, a connecting assembly is provided between the clamping lathe and the honing lathe.

[0021] By adopting the above technical solution, when using an oilstone to process the inner hole, the contact area between the top extension surface and the contact surface on the oilstone is reduced when the top extension component moves laterally. The top extension surface and the contact surface slide relative to each other, and the oilstone can perform radial expansion and contraction, so that the diameter of the honing head can change, which can better adapt to the processing of parts with different inner diameters.

[0022] Optionally, the honing lathe is provided with a limiting block to limit the travel of the drive plate.

[0023] By adopting the above technical solution, a limit block is set on one side of the honing lathe. When the drive plate moves, the limit block restricts the movement of the drive plate, thereby limiting the movement distance of the drive plate during honing.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] This application discloses a simplified horizontal long-stroke honing machine tool.

[0030] refer to Figure 1 A simplified horizontal long-stroke honing machine tool includes a clamping lathe 1, a honing head 2, a honing connecting rod 5, a honing lathe 4, and a drive unit 3. The clamping lathe 1 is used to clamp the workpiece, and the workpiece is rotated via the spindle of the clamping lathe 1. The honing lathe 4 is connected to one side of the clamping lathe 1 and is used to extend the clamping lathe 1. The drive unit 3 is slidably mounted on the honing lathe 4, and the honing head 2 is mounted on the drive unit 3 via the honing connecting rod 5. The drive unit 3 is used to drive the honing head 2 to move horizontally to extend into the inner hole of the workpiece for machining. The honing connecting rod 5 is used to extend the honing head 2.

[0031] When the workpiece needs to be honing, the honing connecting rod 5 is driven by the drive device 3 to approach the clamping lathe 1. As the honing head 2 on the honing connecting rod 5 enters the inner hole of the long and deep sleeve-type part, the workpiece is rotated by the spindle of the clamping lathe 1 to hone the long and deep sleeve-type part.

[0032] refer to Figure 2 A connecting assembly 19 is provided between the honing lathe 4 and the clamping lathe 1. The connecting assembly 19 includes a transition plate 20 connecting the clamping lathe 1 and the honing lathe 4, a support adjustment plate 21 for supporting the honing lathe 4, and an adjustment member 22 installed on the support adjustment plate 21. The transition plate 20 is fixed to the clamping lathe 1 by integral welding or screw connection. The support adjustment plate 21 is located on the side of the transition plate 20 away from the clamping lathe 1, and the support adjustment plate 21 is also located below the honing lathe 4.

[0033] refer to Figure 2 In this embodiment, the adjusting member 22 is a screw. The adjusting member 22 is threaded onto the support adjusting plate 21 and is symmetrically arranged on both sides of the support adjusting plate 21. After passing through the support adjusting plate 21, the adjusting member 22 abuts against the bottom of the honing lathe 4.

[0034] By rotating the adjusting member 22, the adjusting member 22 can lift the honing lathe 4. When the honing lathe 4 and the clamping lathe 1 are at the same height, the transition plate 20 and the honing lathe 4 are bolted together.

[0035] refer to Figure 2 and Figure 3 The drive unit 3 includes a drive plate 10, a motor assembly 12, and a top extension cylinder 11. The drive plate 10 is slidably mounted on the top of the honing lathe 4. The motor assembly 12 is mounted on the drive plate 10 and provides power to drive the drive plate 10 to move. The top extension cylinder 11 is mounted on the top of the drive plate 10 and drives the honing head 2 to process inside the workpiece.

[0036] refer to Figure 3 The motor assembly 12 includes a geared motor 13 for providing power, a gear set 14 for transmitting power, and a sprocket 15 for converting rotation into linear motion. The gear set 14 is connected to the output end of the geared motor 13, and the sprocket 15 is rotatably mounted on the drive plate 10 and meshes with the gear set 14. When the geared motor 13 is running, it drives the sprocket 15 to rotate via the gear set 14.

[0037] A chain 16 is laid flat on the honing lathe 4 and is arranged in a straight line. Both ends of the chain 16 are fixedly connected to the honing lathe 4 so that the chain 16 will not move on the honing lathe 4.

[0038] The sprocket 15 is engaged with the chain 16. When the sprocket 15 rotates, the chain 16 remains stationary, so the sprocket 15 can move along the laying direction of the chain 16, thereby enabling the drive plate 10 to move linearly on the honing lathe 4.

[0039] refer to Figure 4 In order to enable the drive plate 10 to move stably in a straight line along the length of the honing lathe 4, a sliding clamp 26 is provided at the bottom of the drive plate 10, and guide rails 25 are symmetrically arranged on both sides of the top of the honing lathe 4, and the sliding clamp 26 is slidably mounted on the guide rails 25.

[0040] refer to Figure 4 The honing lathe 4 is also fixedly equipped with a limiting block 24 for restricting the movement of the drive plate 10. The limiting block 24 is located at both ends of the movement path of the drive plate 10. When the drive plate 10 moves and contacts the limiting block 24, the limiting block 24 can limit the drive plate 10 so that the drive plate 10 stops moving.

[0041] refer to Figure 4 The drive plate 10 is also provided with a mounting base 31. The extension cylinder 11 is mounted on the drive plate 10 through the mounting base 31, and the push rod of the extension cylinder 11 passes through the mounting base 31. The honing connecting rod 5 is fixedly connected to the mounting base 31.

[0042] refer to Figure 5 The honing head 2 includes a honing head housing 6, honing stones 7, and an extension assembly 8. There are at least two honing stones 7; in this embodiment, there are four honing stones 7, which are circumferentially and evenly mounted on the honing head housing 6. The honing stones 7 pass through the honing head housing 6 and are capable of radial extension and retraction on the honing head housing 6. The bottom of the honing stone 7 has an abutment surface 27, which is inclined.

[0043] refer to Figure 5 The top extension assembly 8 includes a top rod 29, a top pin 30, and a top shaft 28. The top rod 29 passes through the honing connecting rod 5 and is connected to the push rod of the top extension cylinder 11. The top shaft 28 extends and retracts within the honing head 2. The top pin 30 is used to connect the top rod 29 and the top shaft 28. The top shaft 28 is tapered and has an inclined top extension surface 23.

[0044] The contact surface 27 and the top extension surface 23 have the same inclination angle and can cooperate, allowing them to slide relative to each other. When the top extension cylinder 11 drives the top shaft 28 to extend or retract, the contact surface 27 and the top extension surface 23 slide relative to each other, thereby causing the honing stone 7 to extend or retract radially. Furthermore, the smaller the contact area between the contact surface 27 and the top extension surface 23, the greater the distance that the honing stone 7 extends beyond the honing head housing 6, thus making the diameter of the honing head 2 larger.

[0045] refer to Figure 5A universal joint 9 is installed between the honing head 2 and the honing connecting rod 5, and the ejector pin 30 passes through the universal joint 9. When the lathe 1 is rotated, the torque of the honing connecting rod 5 is reduced through the universal joint 9 to ensure the stability of honing.

[0046] Because the honing connecting rod 5 is relatively long, in order to reduce the shaking of the honing head 2 during movement and improve the stability during processing, a cantilever bracket 17 is provided on the top of the honing lathe 4. The top of the cantilever bracket 17 has a support groove 32 for supporting the honing connecting rod 5, and a wear-resistant copper sleeve 18 is installed inside the support groove 32. The honing connecting rod 5 can be supported within the support groove 32 and slide against the wear-resistant copper sleeve 18.

[0047] Combination Figures 1 to 5 The principle of a simple horizontal long-stroke honing machine tool according to an embodiment of this utility model is as follows: When honing is required, the geared motor 13 drives the sprocket 15 to rotate on the chain 16, thereby driving the drive plate 10 to move horizontally, thus extending the honing head 2 into the inner hole of the workpiece. Then, the extension cylinder 11 drives the extension assembly 8 to extend and retract, thereby extending the honing stone 7 axially to the outside of the honing head housing 6 to abut against the inner surface of the workpiece. By rotating the spindle of the clamping lathe 1, the workpiece is driven to rotate, at which time the honing stone 7 can perform honing processing on the workpiece inside the workpiece.

[0048] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
