Description

Technical Field

[0001] This utility model relates to the field of shaft parts processing technology, and in particular to a lathe grinding device. Background Technology

[0002] The traditional machining method for shaft parts involves rough machining on a lathe, followed by semi-finishing with a certain machining allowance, before proceeding to the next step on an external cylindrical grinding machine. Because this process involves multiple steps, each requiring preparation and time, the overall production efficiency is relatively low, leading to longer production cycles and increased costs. Furthermore, in multi-step production lines, a malfunction or need for adjustment in any step can necessitate a lengthy shutdown for repairs or adjustments, impacting production flexibility.

[0003] In view of this, the present invention proposes a lathe grinding device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies. In order to combine the roughing, semi-finishing, and finishing processes on a lathe, improve the processing efficiency of shaft parts, and reduce production costs, a lathe grinding device is proposed. This device adds a shaft external cylindrical grinding machine to the lathe body. Specifically, the tool post and small slide on the lathe slide are removed, and then the sliding assembly and grinding assembly are installed in the original tool post position to achieve the grinding and finishing of shaft workpieces.

[0005] The specific technical solution provided by this utility model is as follows:

[0006] A lathe grinding apparatus, comprising:

[0007] The lathe body has an extendable work platform with longitudinal slide rails on it.

[0008] A chuck, mounted on the lathe body, is used to clamp the workpiece;

[0009] The sliding component is located on the working platform and is connected to the longitudinal slide rail via a slide box. The slide box is equipped with a transverse slide rail that enables lateral sliding.

[0010] The grinding assembly is installed on the upper part of the sliding assembly and connected to the sliding assembly. It can move laterally and longitudinally with the sliding assembly and abut against the workpiece surface on the chuck to grind the workpiece held by the chuck.

[0011] Furthermore, the sliding assembly includes a slide box and a middle slide plate. The slide box is provided with a longitudinal slide groove that corresponds to and matches the longitudinal slide rail. A transverse slide rail is provided on the top of the slide box. The slide box is connected to the middle slide plate through the transverse slide rail. A transverse slide groove that corresponds to and matches the transverse slide rail is provided on the bottom of the middle slide plate.

[0012] Furthermore, the sled box includes a box body and box side panels. The box body is installed on the side wall of the work platform, and the box side panels are connected to the box body and set perpendicular to the work platform. The entire sled box can move longitudinally along the work platform.

[0013] Furthermore, the grinding assembly includes a middle support plate, a bracket, a driver, and a grinding head. The bottom of the middle support plate is connected to the middle slide plate, and a fixed bracket is provided on the upper part of the middle support plate. The driver and the grinding head are connected to the fixed bracket. The end of the driver is rotatably connected to the grinding head, and the driver can drive and control whether the grinding head is running.

[0014] Furthermore, the middle support plate and the middle slide plate are connected by a fastener, and when the fastener is loosened, the middle support plate can rotate within a preset range, thereby adjusting the displacement of the grinding head to achieve inclined surface grinding between the grinding head and the workpiece.

[0015] Furthermore, the middle slide plate is provided with an arc protrusion that facilitates the adjustment of the middle slide plate angle, or the middle slide plate is provided with a groove that facilitates the adjustment of the middle slide plate angle.

[0016] Furthermore, the chuck includes a chuck body and chuck jaws. The chuck body is mounted on the lathe body, and several chuck jaws are provided on the end of the chuck body near the grinding assembly.

[0017] Furthermore, several disc jaws are evenly arranged on the end face of the disc base. The end face of the disc jaws near the workpiece is smooth and in contact with the workpiece, while the end face of the disc jaws far from the workpiece is arranged in a stepped manner.

[0018] Furthermore, the disk base is disc-shaped, and a disk hole for clamping and fixing the workpiece is provided in the middle of the disk base.

[0019] Furthermore, the workpiece is a shaft-type workpiece.

[0020] This utility model provides a lathe grinding device, which has the following beneficial technical effects:

[0021] This invention modifies an existing lathe for roughing and semi-finishing shaft parts. Specifically, the tool post and small slide are removed from the lathe's slide plate, and then the sliding assembly and grinding assembly are installed in the original tool post position to achieve grinding and finishing of shaft workpieces. This allows for the merging of roughing and finishing processes, reducing production costs.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] As attached Figure 1-4 As shown, this utility model discloses a lathe grinding device, comprising:

[0033] The lathe body 1 has an extendable work platform 11, on which a longitudinal slide rail is provided;

[0034] Chuck 2, mounted on lathe body 1, is used to clamp workpiece 5;

[0035] The sliding component 3 is located on the working platform 11 and is connected to the longitudinal slide rail via the slide box 31. The slide box 31 is provided with a transverse slide rail that can achieve lateral sliding.

[0036] The grinding component 4 is installed on the upper part of the sliding component 3 and connected to the sliding component 3. It can move laterally and longitudinally with the sliding component 3 to contact the surface of the workpiece 5 on the chuck 2 and is used to grind the workpiece 5 held by the chuck 2.

[0037] It should be noted that the lathe grinding device in this utility model is a modification of the original lathe for roughing and semi-fine machining of shaft parts. The tool post and small slide plate on the slide plate 32 of the lathe are removed, and then the sliding component 3 and the grinding component 4 are installed in the original tool post position to achieve the grinding and finishing of the workpiece 5. Furthermore, it can combine the roughing and finishing processes to reduce production costs.

[0038] Furthermore, the lathe body 1 is a cuboid structure with a side boss, which is a protruding work platform 11. The work platform 11 can be used to support the sliding assembly 3 and the grinding assembly 4, providing operating space for the grinding process of the workpiece 5.

[0039] A chuck 2 is mounted on the side of the working platform 11 of the lathe body 1 to hold the workpiece 5 to be ground. When the device is running, the sliding component 3 drives the grinding component 4 to move and come into contact with the workpiece 5 to be ground to perform the grinding process.

[0040] As an embodiment of this application, the chuck 2 includes a chuck base 21 and chuck jaws 22. The chuck base 21 is mounted on the lathe body 1, and a plurality of chuck jaws 22 are provided on the end of the chuck base 21 near the grinding assembly 4. (See attached...) Figure 1As shown, the chuck 2 adopts a structure of disc base 21 and multiple disc jaws 22, which makes the clamping of workpiece 5 more secure and reliable, while facilitating quick clamping and replacement of workpiece 5, improving processing efficiency and safety, and is suitable for clamping requirements of workpiece 5 of various specifications.

[0041] Obviously, the chuck 2 is mounted on the side wall of the lathe body 1 by means of a fastener, and the side wall on which it is mounted is close to the end side wall of the grinding assembly 4. Alternatively, the chuck 2 can also be detached by means of a snap-fit ​​setting, a fitting setting, or other detachable methods, and those skilled in the art can choose the design according to actual needs.

[0042] Furthermore, a number of chuck jaws 22 are evenly distributed on the end face of the disc base 21. The end face of the chuck jaws 22 near the workpiece 5 is smooth and abuts against the workpiece 5, while the end face of the chuck jaws 22 far from the workpiece 5 is arranged in a stepped manner. The even distribution of the chuck jaws 22 on the end face of the disc base 21, with the smooth end face near the workpiece 5, helps protect the surface of the workpiece 5 from scratches; the stepped arrangement of the end face far from the workpiece 5 enhances the clamping force and anti-slip performance, making the workpiece 5 more securely clamped and preventing displacement or detachment during processing.

[0043] Optionally, the contact surface between the chuck jaws 22 and the workpiece 5 can be set as a curved surface or a flat surface, which can be determined according to the structure of the workpiece 5 to be ground. When the workpiece 5 to be ground has a cylindrical, conical, or other similar structure, the contact surface between the chuck jaws 22 and the workpiece 5 can be set as a curved surface. When the workpiece 5 to be ground has a cuboid, cube, polyhedron, or other similar structure, the contact surface between the chuck jaws 22 and the workpiece 5 can be set as a flat surface, such as a rectangle, square, or polygon.

[0044] Furthermore, the disk base 21 is disc-shaped, and a disk hole for clamping and fixing the workpiece 5 is provided in the center of the disk base 21. The disc shape of the disk base 21 and the disk hole in the center facilitate the center positioning and clamping of the shaft workpiece 5. The structure is simple and reasonable, the clamping accuracy is high, which helps to achieve the coaxiality machining of the workpiece 5 and improves the overall machining quality.

[0045] As an example of this application, see the attached document. Figure 1 , 2 As shown in Figure 4, the sliding assembly 3 includes a slide box 31 and a middle slide plate 32. The slide box 31 (side bottom wall) is provided with a longitudinal slide groove that corresponds to and matches the longitudinal slide rail. A transverse slide rail is provided on the top of the slide box 31, and the slide box 31 is connected to the middle slide plate 32 through the transverse slide rail. The bottom of the middle slide plate 32 is provided with a transverse slide groove that corresponds to and matches the transverse slide rail. By setting the sliding assembly 3, which includes the slide box 31 and the middle slide plate 32, and adopting a structure in which the longitudinal slide groove matches the longitudinal slide rail and the transverse slide groove matches the transverse slide rail, the sliding assembly 3 runs more smoothly and reliably, ensuring stability during the grinding process, thereby further improving the processing quality and precision.

[0046] As attached Figure 1 As shown, there are two longitudinal sliding grooves on the slide box 31. One groove is located on the side arm of the top surface of the slide box 31, and the other groove is located on the bottom wall of the side plate 312, which matches the longitudinal sliding rails of the working platform 11.

[0047] Furthermore, the slide box 31 includes a box body 311 and a side plate 312. The box body 311 is installed on the side wall of the working platform 11, and the side plate 312 is connected to the box body 311 and is set perpendicular to the working platform 11. The slide box 31 as a whole can move longitudinally along the working platform 11. The slide box 31 has a compact overall structure, is stably installed, and is easy to maintain and adjust, ensuring stable sliding on the longitudinal slide rails and improving the reliability of equipment operation.

[0048] Obviously, the slide box 31 in this application can realize the longitudinal and lateral movement of the grinding assembly 4. The slide box 31 also includes a crank 313 and a connecting rod. The crank 313 is an arm-shaped connecting rod fixed on a shaft, which can rotate around the shaft. The connecting rod can connect the crank 313 and the middle slide plate 32. One end of the connecting rod is connected to the crank 313 through a pin shaft at the center of the crank 313 shaft, and the other end is connected to the middle slide plate 32 through a pin shaft on the slide plate. The length of the connecting rod determines the range of motion of the middle slide plate 32.

[0049] The slide box 31 is also equipped with a coupling, a cam, and a clutch. One end of the coupling is connected to the connecting rod, and the other end is connected to the side plate 312. The connection between the coupling and the connecting rod is equipped with a cam and a clutch. The cam and the matching clutch enable the separate rotation of different connecting rods. The coupling drives the slide box 31 to move the side plate 312 back and forth in a longitudinal feed motion. The connecting rod drives the middle slide plate 32 to move laterally. The driving force (manual drive or motor drive) is applied to the connecting rod through the crank 313. The movement of the connecting rod transmits kinetic energy to the middle slide plate 32 and / or the slide box 31.

[0050] As an example of this application, see the attached document. Figure 1 , 3 As shown, the grinding assembly 4 includes a middle support plate 41, a bracket 42, a driver 43, and a grinding head 44. The bottom of the middle support plate 41 is connected to the middle slide plate 32. The bracket 42 is provided on the upper part of the middle support plate 41. The driver 43 and the grinding head 44 are connected on the bracket 42. The end of the driver 43 is rotatably connected to the grinding head 44, and the driver 43 can drive and control whether the grinding head 44 is running.

[0051] The grinding assembly 4 enables automatic operation control of the grinding head 44, improving the automation level of the grinding operation. The driver 43 can effectively control the start and stop of the grinding head 44, making operation convenient, improving work efficiency and reducing manual labor intensity.

[0052] Furthermore, the middle support plate 41 and the middle slide plate 32 are connected by a fastener, and when the fastener is loosened, the middle support plate 41 can rotate within a preset range, thereby adjusting the displacement of the grinding head 44 to achieve inclined surface grinding between the grinding head 44 and the workpiece 5.

[0053] Optionally, the middle slide plate may be provided with an arc protrusion that facilitates the adjustment of the angle of the middle slide plate 41, or the middle slide plate 32 may be provided with a groove that facilitates the adjustment of the angle of the middle slide plate 41. The arc protrusion or groove helps to make the angle adjustment of the middle slide plate 41 smoother and more stable, improves the adjustment accuracy and operation convenience, thereby enhancing the adaptability of the grinding head 44 at different angles and improving the processing flexibility and quality.

[0054] The middle support plate 41 can be manually rotated by external force to achieve the adjustment effect, or those skilled in the art can also achieve automatic rotation of the middle support plate 41 by setting a matching rotator.

[0055] Furthermore, the shape of the arc protrusion can be selectively designed to facilitate the rotation of the middle support plate 41. For example, when the middle support plate is circular, an arc protrusion or groove with rounded corners can be provided; when the middle support plate is square, an arc protrusion with rounded corners can be provided.

[0056] It should be noted that workpiece 5 in this application is a shaft-type workpiece in machining.

[0057] Compared with the prior art, the above embodiments in this application have the following beneficial technical effects:

[0058] (1) This utility model modifies an existing lathe for roughing and semi-fine machining of shaft parts. The tool post and small slide plate on the slide plate 32 of the lathe are removed, and then the sliding component 3 and the grinding component 4 are installed in the original tool post position to achieve grinding and finishing of shaft workpiece 5. It can realize the merging of roughing and finishing processes, reduce the failure rate of multi-process processing, and reduce production costs.

[0059] (2) By setting the sliding component 3, the longitudinal and transverse feed movements of the grinding component 4 are realized, thereby realizing the grinding of the workpiece 5; when the grinding component 4 is grinding the workpiece 5, the angle of the contact surface between the grinding head 44 of the grinding component 4 and the workpiece 5 is adjusted by adjusting the rotating slide, thereby completing the inclined surface grinding of the workpiece 5.
