Description

Technical Field

[0001] This utility model relates to the field of lathe fixture technology, specifically a fixture structure for a lathe. Background Technology

[0002] A lathe is a machine tool that uses a cutting tool, which performs feed motion, to cut a workpiece that performs rotary motion. The machining principle of a lathe is to mount the cutting tool and the workpiece on the lathe, and the relative motion between the cutting tool and the workpiece, i.e., the cutting motion, is generated by the lathe's transmission and speed change system to cut out parts that meet the requirements. Lathes have a wide machining range, mainly machining rotating surfaces, and can turn outer diameters, turn end faces, cut grooves, drill holes, bore holes, turn tapered surfaces, turn threads, turn shaped surfaces, drill center holes, and perform knurling, etc. Therefore, lathes are now being used more and more widely. A chuck is a mechanical device used on a machine tool to clamp the workpiece.

[0003] For workpieces that require machining at both ends, the workpiece is usually fixed on the chuck first, and one end of the workpiece is machined. After one end of the workpiece is machined, the operator removes the workpiece from the chuck, flips it over, and fixes it back on the chuck using the jaws. The workpiece flipping process is too many, which increases the labor intensity of the operators, is time-consuming and labor-intensive, and affects the processing efficiency of the machine tool.

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide a fixture structure for a lathe, in which a motor drives a threaded rod to rotate, causing the threaded sleeve to perform a threaded feed action along the outside of the threaded rod, thereby changing the height position of the bracket and adjusting the height of the workpiece clamped on the three-jaw chuck. Furthermore, by rotating the motor to drive the three-jaw chuck, multi-angle adjustment processing can be achieved. At the same time, the setting of ball bearings can improve the smoothness of the up and down adjustment process.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] This utility model provides a clamping structure for a lathe. Please refer to [link / reference]. Figure 1-3It includes a connecting frame 100, an adjusting assembly 200, and a connecting assembly 300;

[0028] Please continue reading. Figure 1-3 The connecting frame 100, which serves as the connecting base frame, has a connecting groove 110 inside and a sliding groove 111 communicating with the connecting groove 110 on the outside.

[0029] The connecting frame 100 has a movable groove 120 on the rear side, and two sets of guide rails 121 are symmetrically threaded in the movable groove 120. Connecting seats 130 are symmetrically threaded on the left and right sides of the connecting frame 100. The connecting seats 130 have positioning holes 131, and two sets of sliding grooves 140 are symmetrically opened on the front side of the connecting frame 100.

[0030] Please continue reading. Figure 1-3 The adjustment component 200 is connected to the connecting frame 100 and includes a motor 210 threaded to the top of the connecting frame 100. The output end of the motor 210 is connected to a threaded rod 211. A threaded sleeve 220 is threaded onto the threaded rod 211. A slide block 221 is integrally formed on the outer side of the threaded sleeve 220 and slides slidingly engages with the first slide groove 111 (the slide block slides with the first slide groove, which restricts the rotation direction of the threaded sleeve, so that when the threaded rod rotates, the threaded sleeve performs a threaded feed action along the outer side of the threaded rod, see the threaded feed structure). A bracket 230 is connected to the outer side of the slide block 221. A ball bearing 231 is rotatably connected to the outer side of the bracket 230. The ball bearing 231 is correspondingly set with the second slide groove 140.

[0031] The bottom of the bracket 230 is connected to the rotary motor 240, the output end of the rotary motor 240 extends to the top of the bracket 230, and the output end of the rotary motor 240 is connected to the three-jaw chuck 241 through a connecting bolt;

[0032] action:

[0033] The motor 210 drives the threaded rod 211 to rotate within the connecting groove 110, causing the threaded sleeve 220 to perform threaded feed along the outside of the threaded rod 211. This, in turn, changes the height of the bracket 230, adjusting the height of the workpiece clamped on the three-jaw chuck 241. Furthermore, by rotating the motor 240 to drive the three-jaw chuck 231, multi-angle adjustment processing can be achieved. At the same time, the ball bearings 231 improve the smoothness of the up-and-down adjustment process.

[0034] Please continue reading. Figure 1The movable groove 120 cooperates with the connecting component 300. The connecting component 300 includes a mounting plate 310 connected to the lathe frame. The mounting plate 310 has a guide groove 311 that slides with the guide rail 121. The front side of the mounting plate 310 has a positioning groove 312 that corresponds to the positioning hole 131. The mounting plate 310 has a mounting hole 320 that is adapted to the external positioning bolt. The mounting hole 320 cooperates with the external positioning bolt to fix the position of the mounting plate 310.

[0035] By sliding the guide rail 121 with the guide groove 311, the lateral position of the connecting frame 100 can be adjusted. It can be finely adjusted on a lathe. When it is adjusted to the specified position, the position is fixed by the external connecting bolt engaging with the positioning groove 312 and the positioning hole 131.

[0036] Working principle: When in use, the motor 210 drives the threaded rod 211 to rotate within the connecting groove 110, causing the threaded sleeve 220 to perform threaded feed along the outside of the threaded rod 211. This, in turn, changes the height of the bracket 230, adjusting the height of the workpiece clamped on the three-jaw chuck 241. Furthermore, by rotating the motor 240 and driving the three-jaw chuck 231, multi-angle adjustment processing can be achieved. At the same time, the ball bearings 231 improve the smoothness of the up-and-down adjustment process. In addition, the guide rail 121 slides and engages with the guide groove 311 to adjust the lateral position of the connecting frame 100, allowing for fine-tuning on a lathe and increasing the adaptability of the structure.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
