Description

Technical Field

[0001] This utility model relates to the field of lathe technology, specifically to a lathe with an automatic locking function on the tailstock. Background Technology

[0002] In the machinery manufacturing industry, CNC lathes are widely used to process disc-shaped or shaft-shaped parts. Shaft-shaped parts are relatively long, requiring the tailstock to hold one end of the workpiece in place while the other end is clamped in a chuck for machining. To adjust the length of the workpiece or repeatedly process parts of a certain length, the tailstock's position on the machine bed guideway needs to be repeatedly adjusted. Currently, the tailstock's movement on the bed guideway is achieved by a special motion device. After the tailstock reaches the set position, it is generally manually locked onto the bed guideway, resulting in high labor intensity, long auxiliary time for part processing, and low production efficiency. The manual locking mechanism makes it difficult to maintain accuracy after each movement and locking, causing many inconveniences in processing and hindering automation.

[0003] Therefore, it is necessary to develop a lathe with an automatic locking function for the tailstock to address the above-mentioned defects. Utility Model Content

[0019] Example Reference Figure 1-3In this embodiment, a lathe with an automatic locking function for the tailstock includes: a bed frame 1, a worktable 2 mounted on the top of the bed frame 1, a main unit housing 6, a tool holder 5, and a base 4 sequentially mounted on the worktable 2, a drive motor and a chuck 7 connected to the main unit housing 6 on the right side, a tool holder 5 fixedly mounted on the tool holder 5, a tailstock 3 corresponding to the chuck 7 mounted on the base 4, a plug-in component 8 slidably mounted on the tailstock 3, and a limit component 9 slidably mounted inside the base 4. The limit component 9 and the plug-in component 8 are detachably connected by a snap-fit ​​structure. This invention achieves automatic locking and separation of the tailstock 3 and the base 4 through the detachable connection of the limit component 9 and the plug-in component 8, solving the problem that existing manual locking structures are difficult to maintain accuracy after each movement and locking, causing many inconveniences in machining and use.

[0020] Specifically, the base 4 has a through hole 301, and the tailstock 3 has a first groove 401 and a second groove 402. The through hole 301 is corresponding to the first groove 401, and the first groove 401 and the second groove 402 are connected.

[0021] It should be explained in detail that the plug-in assembly 8 includes: a first connecting shaft 802 slidably connected to the through hole 301; a first limiting block 803, a second limiting block 804, and a third limiting block 805 are sleeved on the first connecting shaft 802 from top to bottom; the first limiting block 803 and the second limiting block 804 are spaced apart; the first limiting block 803 and the second limiting block 804 are both fixedly connected to the first connecting shaft 802; the third limiting block 805 is slidably connected to the first connecting shaft 802; a first plug 806 is fixedly connected to one end of the first connecting shaft 802 near the third limiting block 805; the first plug 806 is spaced apart from the third limiting block 805; the first plug 806 is engaged with the limiting assembly 9; a fixing block 801 is provided on the through hole 301 to prevent the first connecting shaft 802 from sliding out of the through hole 301; and a third groove is provided on the first plug 806 to accommodate the third limiting block 805.

[0022] It is worth noting that the limiting component 9 includes: a second connecting shaft 902 slidably connected to the second groove 402; an annular fourth limiting block 901 is provided in the second groove 402; the fourth limiting block 901 is slidably sleeved on the second connecting shaft 902; a second plug 904 is fixedly connected to one end of the second connecting shaft 902 near the first connecting shaft 802; the second plug 904 is engaged with the third limiting block 805; and a spring 903 is sleeved on the second connecting shaft 902; one end of the spring 903 abuts against the fourth limiting block 901, and the other end abuts against the necked portion of the second groove 402.

[0023] Preferably, the cross-section of the third limiting block 805 is hexagonal. The diameter of the end of the third limiting block 805 closest to the second limiting block 804 is smaller than the diameter of the second limiting block 804.

[0024] In this invention, by inserting the first plug 806 into the first groove 401 and engaging the third limiting block 805 with the second plug 904, the first connecting shaft 802 can be prevented from sliding out of the first groove 401, thus fixing the tailstock 3 to the base 4. When it is necessary to separate the tailstock 3 from the base 4, the operator presses down on the top of the first connecting shaft 802, causing the third limiting block 805 to move downward. When the second plug 904 is on the top side of the third limiting block 805, the operator pulls the top of the first connecting shaft 802 upward. As the first connecting shaft 802 moves upward, the second plug 904 presses the lower half of the third limiting block 805 into the third groove on the first plug 806. Subsequently, the second plug 904 is pressed into the second groove, and the first plug 806 slides out of the first groove 401, separating the tailstock 3 from the base 4, thus achieving automatic locking and separation of the tailstock 3 and the base 4.

[0025] The working process of the lathe with automatic locking function in this embodiment is as follows: Align the tailstock 3 with the base 4. Insert the first plug 806 into the first groove 401. The third limiting block 805 engages with the second plug 904, which can prevent the first connecting shaft 802 from sliding out of the first groove 401, thus fixing the tailstock 3 on the base 4. When the operator presses down on the top of the first connecting shaft 802, the third limiting block 805 moves downward. When the second plug 904 is on the top side of the third limiting block 805, the operator pulls the top of the first connecting shaft 802 upward. As the first connecting shaft 802 moves upward, the second plug 904 squeezes the lower half of the third limiting block 805 into the third groove on the first plug 806. Then, the second plug 904 is squeezed into the second groove, and the first plug 806 slides out of the first groove 401. The tailstock 3 separates from the base 4, which solves the problem that the existing manual locking structure is difficult to maintain after each movement and locking, causing many inconveniences for processing and use.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
