Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a spring chuck clamping mechanism for numerically controlled lathes. Background Art

[0002] A CNC lathe, or digitally controlled lathe, is an automated machine tool that utilizes digital information technology to operate. It controls the movement and processing of the machine tool according to preset program instructions, enabling precision machining of shaft or disc parts. A spring chuck is an efficient and precise clamping tool on a CNC lathe, primarily used to clamp small-diameter workpieces for machining.

[0003] The existing spring chuck device has a poor effect on limiting the chuck body, which easily leads to unstable clamping of the chuck body on the tool body, causing the tool body to fall during use, which is dangerous and reduces the processing efficiency of the device. Therefore, we propose a CNC lathe spring chuck clamping mechanism to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a spring chuck clamping mechanism for a CNC lathe to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A spring chuck clamping mechanism for a CNC lathe includes a connecting seat, a support rod is provided at the bottom of the connecting seat, a chuck body is provided at the bottom of the support rod, a corresponding fixed sleeve is provided on the outside of the chuck body, a sliding cylinder is provided on the outer movable sleeve of the support rod, and limit blocks are fixedly installed on the left and right sides of the inner cavity of the sliding cylinder, and the corresponding sides of the limit blocks extend to the interior of the support rod, and positioning rods are fixedly installed on the left and right sides of the bottom of the sliding cylinder, and the bottom of the positioning rod extends to the interior of the fixed sleeve.

[0007] Preferably, positioning nuts are provided at the four corners of the bottom of the connecting seat. The number of the positioning nuts is four groups and they are distributed in a circular array. A positioning stud is fixedly installed on the top of the positioning nut, and the top thread of the positioning stud passes through the connecting seat.

[0008] Preferably, the left and right sides of the support rod are fixedly provided with limiting grooves adapted to the limiting block, the top of the inner cavity of the limiting groove is fixedly connected to a first spring, and the bottom of the first spring is fixedly connected to the top of the limiting block.

[0009] Preferably, the outer side of the fixing sleeve is fixedly inlaid with an anti-slip pad, and the outer side of the top of the fixing sleeve is fixedly provided with a slot adapted to the positioning rod, and the number of the slots is several and distributed in a ring array.

[0010] Preferably, the bottom of the support rod extends to the inner cavity of the fixing sleeve, the top of the outer side of the support rod contacts the top thread of the inner wall of the fixing sleeve, the bottom of the connecting seat is fixedly connected to the top of the support rod, and the bottom of the support rod is fixedly connected to the top of the chuck body.

[0011] Preferably, a cutter body is provided at the bottom of the chuck body, and the top of the cutter body extends into the interior of the chuck body.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In the utility model, the slide cylinder, the limit block, the limit slot, the first spring, the slot, the positioning rod and the fixing sleeve are used in coordination. By sliding the slide cylinder upward, the slide cylinder drives the limit block and the positioning rod to move upward at the same time. When the limit block moves upward, the first spring is compressed, and then the cutter body is inserted into the interior of the chuck body. Then, the fixing sleeve is rotated forward, and the fixing sleeve moves upward by cooperating with the support rod screwed thereto to fix the cutter body. Then, the slide cylinder is released, and the positioning rod can be reset by the elastic force of the first spring, so that the bottom of the positioning rod extends into the inner cavity of the slot, which can quickly limit the fixing sleeve, thereby avoiding the cutter body from falling during use and improving the working efficiency of the device.

[0014] 2. In the utility model, the connecting base, the positioning nut and the positioning stud cooperate with each other. By connecting the connecting base to the external device, and then rotating the positioning nut forward, the positioning nut drives the positioning stud to rotate, so that the connecting base can be fixed, thereby improving the stability of the device.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3 A spring chuck clamping mechanism for a CNC lathe includes a connecting seat 1, a support rod 2 is provided at the bottom of the connecting seat 1, a chuck body 3 is provided at the bottom of the support rod 2, a corresponding fixed sleeve 5 is provided on the outside of the chuck body 3, and a movable sleeve on the outside of the support rod 2 is provided with a slide 6. The left and right sides of the inner cavity of the slide 6 are fixedly installed with limit blocks 7, and the corresponding sides of the limit blocks 7 extend to the inside of the support rod 2. Positioning rods 12 are fixedly installed on the left and right sides of the bottom of the slide 6, and the bottom of the positioning rod 12 extends to the inside of the fixed sleeve 5.

[0021] In this embodiment, positioning nuts 13 are provided at the four corners of the bottom of the connecting seat 1. The number of positioning nuts 13 is four groups, and they are distributed in a circular array. A positioning stud 14 is fixedly installed on the top of the positioning nut 13. The top thread of the positioning stud 14 passes through the connecting seat 1. The left and right sides of the support rod 2 are fixed with limiting grooves 8 that are compatible with the limiting block 7. The top of the inner cavity of the limiting groove 8 is fixedly connected to the first spring 9, and the bottom of the first spring 9 is fixedly connected to the top of the limiting block 7. Through the cooperation of the limiting block 7 and the limiting groove 8, the slide 6 can be limited, thereby improving the stability of the up and down movement of the slide 6.

[0022] In this embodiment, the outer side of the fixing sleeve 5 is fixedly inlaid with an anti-slip pad 11, and the outer side of the top of the fixing sleeve 5 is fixedly provided with a slot 10 adapted to the positioning rod 12. The number of the slots 10 is several and distributed in a circular array. The bottom of the support rod 2 extends to the inner cavity of the fixing sleeve 5, and the top of the outer side of the support rod 2 is in contact with the top thread of the inner wall of the fixing sleeve 5. The bottom of the connecting seat 1 is fixedly connected to the top of the support rod 2, and the bottom of the support rod 2 is fixedly connected to the top of the chuck body 3.
