[0001] This utility model relates to a workpiece chuck, specifically a lathe mouth-type workpiece chuck, belonging to the field of lathe equipment technology. Background Technology

[0002] A lathe is a machine tool primarily used to machine rotating workpieces using a cutting tool. It is the most important type of metal cutting machine tool, and is the most numerous and prevalent type in general machine manufacturing plants; it is also known as the "mother machine." Drills, reamers, taps, dies, and knurling tools can also be used on lathes for various machining operations. The function of a lathe is to cut rotating surfaces of various sizes and shapes, as well as helical surfaces.

[0003] However, existing lathes typically use claw-shaped chucks to clamp workpieces, which usually requires manual operation by the user to ensure a secure clamping. When machining a large number of workpieces, this requires repeated operation by the user, affecting production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a lathe mouth-type workpiece chuck to solve the above problems. By setting a clamping block divided into four parts on the inner side of the mounting sleeve, a cylindrical workpiece is clamped. When the clamping block is pushed to slide inside the mounting sleeve, the clamping block can be opened and tightened, which effectively improves the efficiency of fixing and removing the workpiece.

[0008] Preferably, the push rod has four positioning grooves arranged in a ring at equal intervals on its side, and the end of the positioning post has a hemispherical structure, with the spherical end of the positioning post abutting against the push rod through the positioning groove.

[0009] Preferably, the end of the mounting sleeve is provided with a receiving groove, and the side of the push rod is fixedly connected with an abutment block, which abuts against the end of the mounting sleeve.

[0010] Preferably, the adjustment structure includes a disassembly block, the side of the clamping block is provided with the disassembly block, and the inner side of the disassembly block has an arc surface structure.

Two positioning posts 207 are slidably connected to the inner side of the limiting block 203. The two positioning posts 207 are arranged opposite to each other on both sides of the push rod 201. A third spring 208 is fixedly connected between the positioning posts 207 and the limiting block 203. Four positioning grooves 209 are equidistantly arranged in a ring on the side of the push rod 201. The end of the positioning post 207 has a hemispherical structure. The spherical end of the positioning post 207 abuts against the push rod 201 through the positioning groove 209. The mounting sleeve 1 has a receiving groove 211 at its end, and the push rod 201 has a contact block 210 fixedly connected to its side. The contact block 210 abuts against the end of the mounting sleeve 1. In order to facilitate the placement of the workpiece while keeping the clamping block 202 in an open state, the receiving groove 211 is provided at the end of the mounting sleeve 1. When the contact block 210 rotates with the push rod 201 to the point where it is misaligned with the receiving groove 211, the push rod 201 cannot push inward. At this time, the clamping block 202 can be kept in an open state. At the same time, in order to facilitate the positioning of the rotation of the push rod 201, a positioning groove 209 is provided on the side of the push rod 201. Combined with the abutting effect of the positioning post 207, the rotation angle of the push rod 201 can be fixed and maintained.

[0024] As a technical optimization of this utility model, the adjustment structure 3 includes a disassembly block 301. The disassembly block 301 is provided on the side of the clamping block 202. The inner side of the disassembly block 301 has an arc-shaped structure. A fixing block 303 is fixedly connected to the side of the disassembly block 301. A fixing groove 302 is opened on the inner side of the clamping block 202. The fixing block 303 is slidably connected to the clamping block 202 through the fixing groove 302. A locking block 304 is fixedly connected to the inner side of the clamping block 202 through the fixing groove 302. The locking block 304 is slidably connected to the side of the fixing block 303. A pushing block 305 is slidably connected to the end of the clamping block 202 through the fixing groove 302. A fourth spring 306 is fixedly connected between the pushing block 305 and the clamping block 202. The end of the pushing block 305 abuts against the end of the fixing block 303. The end of the clamping block 202 has a beveled structure. To facilitate clamping and fixing rod-shaped parts of different specifications, a replaceable disassembly block 301 is provided on the inner side of the clamping block 202. By replacing the disassembly block 301 with different inner diameters, workpieces of different thicknesses can be fixed effectively. When disassembling and assembling the disassembly block 301, the user first needs to ensure that the clamping block 202 is in the open state, and then slide the disassembly block 301 outward. At this time, the fixing block 303 on the side of the disassembly block 301 will slide to the other side of the fixing groove 302 and push the pushing block 305 back. After the fixing block 303 disengages from the locking block 304, the disassembly block 301 can be removed directly. Since the side of the pushing block 305 has a beveled structure, the user can quickly install a new disassembly block 301. The pushing block 305 applies a pushing force to the fixing block 303 to prevent the disassembly block 301 from falling off.

[0025] In use, this invention firstly has four clamping blocks 202 forming a conical structure located inside the mounting sleeve 1. The inner side of the tail end of each clamping block 202 is a conical surface. Simultaneously, the inner side of each clamping block 202 is restricted by the end of a limiting block 203. A second spring 206 is installed in the annular groove 205 on the outer side of each clamping block 202, causing the clamping block 202 to have a rotational tendency around its contact point with the limiting block 203. When the limiting block 203 slides inside the mounting sleeve 1, the unrestricted clamping block 202 will rotate, causing the four clamping blocks 202 to rotate. 02 is in the open state. At this time, the user can directly place the rod-shaped component to be clamped and fixed in the middle of the clamping block 202, and then return the limiting block 203 to its original position. The side of the clamping block 202 then slides back to the inside of the mounting sleeve 1, causing the clamping block 202 to tighten and thus complete the clamping and fixing of the rod-shaped component. This method is convenient to operate and has high installation efficiency. To facilitate the placement of the workpiece while keeping the clamping block 202 in the open state, a receiving groove 211 is provided at the end of the mounting sleeve 1. When the abutment block 210 rotates with the push rod 201 to a position where it is misaligned with the receiving groove 211, the push rod... Since 201 cannot be pushed inward, clamping block 202 remains in the open state. To facilitate positioning the rotation of push rod 201, a positioning groove 209 is provided on the side of push rod 201. Combined with the abutting effect of positioning post 207, the rotation angle of push rod 201 can be fixed and maintained. To facilitate clamping and fixing rod-shaped parts of different specifications, a replaceable disassembly block 301 is provided inside clamping block 202. By replacing disassembly blocks 301 with different inner diameters, workpieces of different thicknesses can be effectively fixed. When disassembling and assembling block 301, the user first needs to ensure that the clamping block 202 is in the open state, and then slide the disassembly and assembly block 301 outward. At this time, the fixing block 303 on the side of the disassembly and assembly block 301 will slide to the other side of the fixing groove 302 and push the pushing block 305 to retract. After the fixing block 303 disengages from the locking block 304, the disassembly and assembly block 301 can be removed directly. Since the side of the pushing block 305 is a sloping structure, the user can quickly install a new disassembly and assembly block 301. The pushing block 305 applies a pushing force to the fixing block 303 to prevent the disassembly and assembly block 301 from falling off.
