Description

Technical Field

[0001] The utility model relates to a novel feeding tail clamp for an automatic lathe. Background Art

[0002] Existing automatic lathes use a tail clamp to feed slender rods. The feed base is inserted into the feed tube through a through-hole, and the tail of the raw rod is then riveted to the feed base. During production, the raw rod rotates at high speed along with the lathe spindle. Consequently, the tail clamp also rotates at high speed along with the raw rod. This structure causes the raw material to vibrate violently during operation, and the feed base is prone to wear, resulting in a short service life. Utility Model Content

[0005] Furthermore, the raw material fixing clamp is formed with a pushing groove; the pushing groove is slidingly provided with a pushing piece for abutting the end face of one end of the insertion hole of the raw material rod; when the pushing piece slides along one end of the pushing groove to the other end, the surface in contact with one end of the raw material rod is flush with the end face of the raw material fixing clamp.

[0006] Furthermore, a baffle is provided on the outer periphery of the feed pipe for limiting the sliding distance of the pusher to limit the surface of the pusher in contact with one end of the raw material rod to be flush with the end surface of the raw material fixing clamp.

[0007] Furthermore, the baffle can be detachably mounted in a clamping groove formed on the outer periphery of the feed pipe by means of a clamping connection.

DETAILED DESCRIPTION

[0018] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0019] like Figure 1 As shown, a new type of automatic lathe feed tail clamp 10 of the present application includes: a feed tube 11, and a feed seat 13 is slidably arranged in the feed tube 11. A feed rotating shaft 14 is rotatably arranged in the feed seat 13, and a raw material fixing clamp 15 is installed at one end of the feed rotating shaft 14 for inserting the raw material rod 100. A connecting hole 152 for adapting to the feed rotating shaft 14 is formed at one end of the raw material fixing clamp 15, and a socket for inserting the raw material rod 100 is formed at the other end. During installation, the raw material fixing clamp 15 is directly inserted into the connecting hole 152, and then the raw material rod 100 is inserted into the socket. High-speed bearings 17 are respectively provided at both ends of the interior of the feeding pipe 11, and two high-speed bearings 17 are sequentially passed through one end of the feeding rotating shaft 14. A shaft fastening screw 18 is threadedly installed at one end of the feeding rotating shaft 14, and an interference step 20 is provided at the other end. The shaft fastening screw 18 can limit the relative position of the feeding rotating shaft 14 and one of the two high-speed bearings 17. The shaft fastening screw 18 can limit the relative position of the feeding rotating shaft 14 and the other of the two high-speed bearings 17.

[0020] Specifically, a sleeve 19 is provided between the shaft fastening screw 18 and one of the two high-speed bearings 17. One end of the sleeve 19 contacts one side of the rotating inner ring of the high-speed bearing 17, and the other end contacts the shaft fastening screw 18. The low-order end face 21 of the contact step 20 contacts one side of the rotating inner ring of the other of the two high-speed bearings 17, and a gap is formed between the high-order end face 22 of the contact step 20 and the end face of the feed base 13. In this way, while the high-speed bearing 17 rotatably supports the feed rotary shaft 14, the shaft fastening screw 18, sleeve 19, and contact step 20 can ensure the stability of the rotating structure between the feed rotary shaft 14 and the feed base 13, resulting in low rotational friction, low wear rate, and a long service life for the entire structure.

[0021] Furthermore, the feeding pipe 11 is formed with a sliding groove 111 for guiding the sliding of the feeding seat 13. The sliding groove 111 can push the feeding seat 13 to move along a straight line, thereby achieving stable feeding.

[0022] As a specific embodiment, the upper end of the feeding seat 13 extends out of the slide groove 111, and the part extending out of the slide groove 111 forms a second top hole 131. The external pushing device can push the feeding seat 13 through the second top hole 131 to push out the feeding, thereby realizing automatic pushing.

[0023] As a specific implementation, the length of the feed tube 11 is greater than the length of the raw material, thereby ensuring the safety of the raw material rod 100 during the loading process of the raw material rod 100.

[0024] As a specific implementation, the slide groove 111 is a through groove with both ends open, which makes it easy to disassemble and assemble the feeding seat 13 and the connecting structure on the feeding seat 13.

[0025] As a specific embodiment, the raw material fixing clamp 15 is detachably mounted on one end of the feeding rotating shaft 14 via a set screw 23 , so that different raw material fixing clamps 15 can be easily replaced according to raw material rods 100 of different diameters.

[0026] The above-mentioned new automatic lathe feed tail clamp 10 embeds high-speed bearings 17 at the front and rear ends of the feed base 13, connects the raw material fixing clamp 15 through the feed rotating shaft 14, and connects the raw material bar 100 through the raw material fixing clamp 15. In this way, the raw material fixing clamp 15 can cooperate with the feed rotating shaft 14 to rotate at high speed, avoiding the raw material bar 100 from vibrating violently during high-speed rotation, improving production stability, and such a structure is not prone to friction and vibration, reducing the wear of the feed base 13 and extending its service life. At the same time, the raw material fixing clamp 15 can be replaced as needed, improving the versatility of the structure.

[0027] As a specific embodiment, the stock retaining clamp 15 is formed with a pushing groove 151, which is slidably provided with a pushing piece 16. The pushing piece 16 contacts the end surface of one end of the insertion hole of the stock rod 100, thereby pushing the stock rod 100 out of the stock retaining clamp 15 at the end of the pushing process. As the pushing piece 16 slides from one end of the pushing groove 151 to the other end, the surface of the pushing piece 16 that contacts one end of the stock rod 100 is flush with the end surface of the stock retaining clamp 15. In other words, at the end of the pushing process, when the stock rod 100 is ejected, the pushing piece 16 is flush with the end surface of the stock retaining clamp 15.

[0028] As a specific embodiment, a baffle 12 is provided on the outer periphery of the feed tube 11. The baffle 12 is used to limit the sliding distance of the pusher 16, thereby limiting the contact surface of the pusher 16 with one end of the raw material rod 100 to be flush with the end surface of the raw material fixing clamp 15. The baffle 12 is removably mounted in a snap-fit ​​manner within a slot 112 formed on the outer periphery of the feed tube 11. In this way, when disassembling the feed base 13, the baffle 12 can be removed.

[0029] As a specific embodiment, the upper end of the push piece 16 extends out of the push groove 151 and the chute 111. The portion of the push piece 16 extending out of the push groove 151 and the chute 111 is formed with a first top hole 161, which makes it easy for an external pushing mechanism to move the push piece 16 through the first top hole 161 to eject the raw material bar 100, thereby realizing automatic pushing.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the scope of protection of the present invention.
