Numerical control lathe positioning clamp

Abstract

The utility model relates to the technical field of numerical control lathe clamps, in particular to a numerical control lathe positioning clamp which comprises a base, a movable groove is formed in the base, and a moving mechanism is arranged in the movable groove. The device is usually used for clamping shaft type columnar objects, so that the objects need to be firmly fixed when being machined, the objects needing to be machined are placed between the fixing plates, meanwhile, the handle is rotated to enable the second threaded rod in transmission connection with the handle to rotate, and due to the fact that the threads at the two ends of the second threaded rod are arranged oppositely, the objects can be machined more stably. The second threaded rod rotates to drive the two ends of the second threaded rod to move in the opposite direction through the threaded blocks movably connected with the second threaded rod through the threaded holes, and therefore the fixing plates fixedly connected with the two ends of the second threaded rod are driven to move to fix an object needing to be machined; and unnecessary cost loss caused by deviation due to infirm clamping during machining of the device is avoided, so that the clamping effect of the device is improved, and the stability of the device is enhanced.

[0013] 1. A positioning fixture for a CNC lathe. This device is often used to clamp shaft-like columnar objects. Therefore, when processing such objects, they need to be firmly fixed. The objects to be processed are placed between the fixed plates, and the handle is turned at the same time to rotate the second threaded rod connected to it. Because the threads at both ends of the second threaded rod are arranged in opposite directions, the rotation of the second threaded rod drives the threaded blocks at both ends of the second threaded rod to move in opposite directions through the threaded holes, thereby driving the fixed plates fixedly connected at both ends to move and fix the objects to be processed. This setting is firmly fixed, so that the device will not cause deviation due to loose clamping during processing, resulting in unnecessary cost losses, thereby improving the clamping effect of the device and enhancing the stability of the device.

[0014] 2. This CNC lathe positioning fixture can rotate the first threaded rod connected to it by turning the handle when the object to be fixed is too long or too short. Since the threads at both ends of the first threaded rod are arranged in opposite directions, the rotation of the first threaded rod drives the movable blocks at both ends of the rod to move in opposite directions through threaded holes, so that the device can be adjusted according to the length of the object to be clamped, thereby enhancing the applicability of the device. The device is simple and labor-saving to operate, which is convenient for operators to operate, thereby improving the work efficiency of operators. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In this embodiment, preferably, the fixing mechanism includes a thread groove 8, a second threaded rod 9 and a thread block 10. A thread groove 8 is opened on one side of the interior of the mounting seat 3. The second threaded rod 9 is movably arranged inside the thread groove 8 through a rotating shaft. The threads at both ends of the second threaded rod 9 are arranged oppositely. The outer sides of both ends of the second threaded rod 9 are movably arranged with thread blocks 10 through threaded holes. The two ends of the thread block 10 pass through the thread groove 8 on the outer side of the mounting seat 3.

[0027] Through the above solution, the device is fixed more firmly, thereby enhancing the stability of the device;

[0028] In this embodiment, preferably, the limiting mechanism includes a slide groove 11, a slide rod 12 and a slider 13.

The objects to be processed are placed between the fixed plates 4, and the handle 15 is turned at the same time to rotate the second threaded rod 9 connected to it for transmission to rotate. Because the threads at both ends of the second threaded rod 9 are arranged in opposite directions, the rotation of the second threaded rod 9 drives the threaded blocks 10 movably connected to it at both ends through the threaded holes to move in opposite directions, thereby driving the fixed plates 4 fixedly connected at both ends to move and fix the objects to be processed. This setting is firmly fixed, so that the device will not cause deviation due to loose clamping during processing, causing unnecessary cost losses, thereby improving the clamping effect of the device and enhancing the stability of the device.

Since the threads at both ends of the first threaded rod 5 are arranged in opposite directions, the rotation of the first threaded rod 5 drives the movable blocks 6 at both ends of the first threaded rod 5 to move in opposite directions, so that the device can be adjusted according to the length of the object to be clamped, thereby enhancing the applicability of the device. The device is simple and labor-saving to operate, and is convenient for operators to operate, thereby improving the work efficiency of operators.
