Description

Technical Field

[0001] The utility model relates to the technical field of lathes, in particular to a fixing device for lathe processing. Background Art

[0002] In existing technology, fixtures for lathe machining are commonly used to secure the product during machining to ensure precision and stability. These fixtures typically include fixtures, chucks, and other tools. Their primary functions are as follows: They secure the product to prevent movement during machining, thereby ensuring machining accuracy; They also provide stable support, ensuring a smoother machining process and reducing vibration and errors.

[0003] Prior art fixtures for lathe machining suffer from numerous significant drawbacks. First, they are severely lacking in versatility. Typically, these fixtures can only accommodate products of specific shapes, significantly limiting production flexibility. For example, different fixtures, such as cubes and cylinders, require replacement for products to be machined. This means that during actual production, whenever the product shape changes, a significant amount of time and manpower must be spent replacing the fixtures, increasing operational complexity and reducing production efficiency. Frequent fixture replacements can also lead to operational errors and affect machining accuracy. Furthermore, different fixtures require additional storage space, increasing costs for the company. Furthermore, the lathe may need to be re-debugged and recalibrated during fixture replacement, further increasing production time and technical complexity. If production is urgent, this frequent fixture replacement can place significant pressure on the company and may even impact on the timely delivery of orders. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0023] Reference Figure 1-4 , a fixing device for lathe processing includes a base 1, on which a product 3 to be processed is placed through a support base 2, a transmission cavity 14, a rotation slot 16 and an equipment slot 21 are provided on the base 1, and an adjustment motor 15 and a rotating motor 22 are respectively provided in the transmission cavity 14 and the equipment slot 21, a screw 17 extending into the transmission cavity 14 is rotatably provided in the rotation slot 16, the screw 17 is connected to the adjustment motor 15 through a transmission mechanism, an adjusting rod 18 is threadedly sleeved on the screw 17, and a rotating frame 6 is rotatably provided on the adjusting rod 18, a double-sided gear ring 4 is rotatably provided on the base 1, the rotating frame 6 is connected to the double-sided gear ring 4 through a meshing mechanism, and the double-sided gear ring 4 is connected to the rotating motor 22 through a rotating mechanism, a mounting block 9 is provided on the rotating frame 6, and a T-shaped plug 10 is slidably penetrated through the mounting block 9 through an elastic mechanism, a limiting slot 12 is provided on the base 1, and a first fixing plate 7 and a second fixing plate 8 are installed on the rotating frame 6.

[0024] The transmission mechanism includes a driving gear 19 mounted on the output shaft of the adjustment motor 15, and a transmission gear 20 mounted on the screw 17, which meshes with the driving gear 19. Both the driving gear 19 and the transmission gear 20 are bevel gears that transmit power from the adjustment motor 15. After the adjustment motor 15 is activated, the four screws 17 rotate synchronously. The four screws 17 are oriented according to their rotational direction to ensure that the four rotating frames 6 move simultaneously, either converging or spreading.

[0025] The meshing mechanism includes a rotating ring gear 13 mounted on the turret 6, meshing with the double-sided ring gear 4. The central portion of the rotating ring gear 13 is vacant for the adjustment rod 18 to connect to the turret 6. The rotating ring gear 13 is designed so that rotation of the double-sided ring gear 4 drives the rotating ring gear 13, which in turn drives the turret 6. The bottom wall of the rotating ring gear 13 slides in contact with the upper end surface of the base 1, limiting the adjustment rod 18 from rotating with the screw 17.

[0026] The rotating mechanism includes an adjusting gear 5 mounted on the output shaft of the rotating motor 22, and the adjusting gear 5 is meshed with the double-sided ring gear 4. Once the rotating motor 22 is started, the adjusting gear 5 can be driven to rotate, and once the adjusting gear 5 is rotated, the double-sided ring gear 4 can be driven to rotate.

[0027] The elastic mechanism includes a spring 11 sleeved around the outside of the T-shaped rod 10. The ends of the spring 11 are elastically connected to the outer wall of the head of the T-shaped rod 10 and the outer wall of the mounting block 9, respectively. The elastic potential energy provided by the spring 11 enables the T-shaped rod 10 to be dragged, ensuring that its tail is located within the retaining groove 12. In this state, the rotating frame 6 cannot rotate. Each rotating frame 6 corresponds to two retaining grooves 12.

[0028] The first fixing plate 7 is a rectangular block, and the second fixing plate 8 is an arc-shaped block. The surfaces of the first fixing plate 7 and the second fixing plate 8 that contact the product 3 to be processed are both provided with rubber pads to prevent the outer wall of the product 3 from being damaged.

[0029] When the utility model is used, Figure 1 In the state shown, the product 3 to be processed is in the shape of a cube, and the rectangular block-shaped first fixed plate 7 faces the product 3 to be processed. At this time, the adjustment motor 15 is started. After the adjustment motor 15 is started, it drives the driving gear 19 to rotate, and the driving gear 19 rotates to drive the transmission gear 20 to rotate. The rotation of the transmission gear 20 can drive the screw 17 to rotate. When the screw 17 rotates, the adjusting rod 18 moves. When the adjusting rod 18 moves, it drives the rotating frame 6 to move. The rotating frame 6 drives the first fixed plate 7 and the second fixed plate 8 to move. Finally, the first fixed plate 7 contacts and fixes the product 3 to be processed.

[0030] After the product 3 to be processed is transformed into a cylindrical shape, the four rotating frames 6 are first moved and spread apart, and the rotating ring gear 13 is engaged with the double-sided ring gear 4, and then the T-shaped rod 10 is dragged to move and the tail is disengaged from the limit slot 12, and then the adjustment motor 15 is started, and the adjustment motor 15 drives the adjustment gear 5 to rotate, and the adjustment gear 5 drives the double-sided ring gear 4 to rotate. The rotation of the double-sided ring gear 4 can drive the rotating ring gear 13 to rotate, thereby driving the rotating frame 6 to rotate. After the four rotating frames 6 rotate 180 degrees, the second fixed plate 8 is directed to the middle. At this time, the T-shaped rod 10 is released, and it drops and resets under the action of the spring 11, and the tail enters another limit slot 12. The rotating frame 6 will not rotate. At this time, the four second fixed plates 8 move closer to clamp and fix the cylindrical product 3 to be processed.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
