Description

Technical Field

[0001] This utility model relates to the field of lathe clamping technology, specifically a double-headed lathe clamping device. Background Technology

[0002] In the machining of shell products using a double-head lathe, problems such as misalignment of the product, high scrap rate, and high tool wear are mainly due to operator negligence or improper operation during loading, positioning, and clamping. The design of the fixture directly affects the product's positioning and clamping. If the fixture design is unreasonable, such as insufficient clamping force or low positioning accuracy, the product is prone to shifting during machining, resulting in misalignment. Currently, manual clamping and adjustment of the clamping position makes it difficult to control the product's clamping position to be at the center of the fixture, easily leading to misalignment, low product quality, high scrap rate, and high tool wear. Therefore, we propose a double-head lathe clamping device to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a clamping device for a double-headed lathe, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a double-headed lathe clamping device, including a slide base, with jaws symmetrically slidably mounted on the top of the slide base about the vertical center line, side plates fixed to both sides of the slide base by bolts, both side plates being rotatably connected to the positive and negative lead screws, a servo motor for driving the positive and negative lead screws to rotate being fixed to one side of the slide base by bolts, and lead screw nuts that mesh with the positive and negative lead screws being fixed to the vertical surfaces at the bottom of both jaws by screws.

[0005] Furthermore, both side plates are perpendicular to the slide base, and two grippers are located between the two side plates.

[0006] Furthermore, the positive and negative lead screws include lead screw A and lead screw B, which are fixedly connected from left to right, with the spiral patterns of lead screw A and lead screw B being opposite.

[0007] Furthermore, the screw nuts of the two grippers engage with screw A and screw B respectively.

[0008] Furthermore, grooves for clamping products are provided on the inner sidewalls of the tips of both grippers.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] The technical solution of this application involves placing the product above two grippers, with a servo motor and forward and reverse lead screws synchronously driving the two grippers to move inward, thereby centering the product and achieving the effect of centering the product position. This improves the accuracy of tool processing and solves the problems of low product quality, high processing scrap rate, and high tool wear. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1, as Figure 1-2 As shown, this utility model provides a technical solution: a double-headed lathe clamping device, including a slide base 5, with cleavers 3 slidably mounted on the top of the slide base 5 about the vertical center line, side plates fixed to both sides of the slide base 5 by bolts, both side plates being rotatably connected to the positive and negative lead screws 4, a servo motor 2 for driving the positive and negative lead screws 4 to rotate being fixed to one side of the slide base 5 by bolts, and lead screw nuts that mesh with the positive and negative lead screws 4 being fixed to the vertical surfaces of the bottom ends of the two cleavers 3 by screws.

[0017] In a specific embodiment of this utility model, a sliding groove is provided on the top of the slide base 5, and a retainer is provided at the bottom of each of the two grippers 3 to engage and slide with the sliding groove. The sliding groove and the retainer are inverted T-shaped. The side plates at both ends of the slide base 5 are rotatably assembled with the positive and negative lead screws 4 by bearings. One end of the positive and negative lead screws 4 extends out of the side plate at one end of the slide base 5, so that the servo motor 2 can be coaxially connected to one end of the positive and negative lead screws 4 through a coupling. The two grippers 3 are respectively engaged with the positive and negative ends of the positive and negative lead screws 4 through lead screw nuts. The servo motor 2 is connected to the controller and the power module. When the servo motor 2 starts, it drives the positive and negative lead screws 4 to move. Since the positive and negative lead screws 4 have two lead screw sections with different helical directions, when the product 1 is placed between the two grippers 3, the two grippers 3 move inward synchronously, thereby centering the product 1 and achieving the effect of centering the product position. This improves the accuracy of tool processing and solves the problems of low product quality, high processing scrap rate, and high tool wear.

[0018] In the preferred technical solution, both side plates are perpendicular to each other with the slide base 5, and the two grippers 3 are located between the two side plates. The positive and negative lead screws 4 include lead screw A and lead screw B fixedly connected from left to right. The spiral patterns of lead screw A and lead screw B are opposite. The positive and negative lead screws 4 can achieve relative or opposite movement of the two grippers 3 by unidirectional drive.

[0019] In the preferred technical solution, the screw nuts of the two grippers 3 are respectively engaged with screw A and screw B. The screw nuts are used to thread with screw A and screw B. When the forward and reverse screws 4 rotate, they drive the two grippers 3 to slide on the slide base 5.

[0020] In the preferred technical solution, the inner sidewalls of the top of the two grippers 3 are provided with grooves for clamping the product 1, so as to stably clamp the product 1.

[0021] In summary, by placing the product above the two grippers 3, the servo motor 2, in conjunction with the forward and reverse lead screws 4, synchronously drives the two grippers 3 to move inward, thereby centering the product 1 and achieving the effect of centering the product position. This improves the accuracy of tool processing and solves the problems of low product quality, high processing scrap rate, and high tool wear.
