Description

Technical Field

[0001] The utility model relates to the technical field of lathe clamps, in particular to a lathe clamp with an anti-drop function. Background Art

[0002] A bed fixture refers to a fixture used on a lathe to process the inner and outer rotating surfaces and end faces of the workpiece. Most lathe fixtures are installed on the spindle, and a few are installed on the saddle or bed. Lathe fixtures are divided into centering type (spindle type), collet type, chuck type, angle iron type and faceplate type according to the different workpiece positioning methods.

[0003] However, the clamping blocks of existing lathe clamps will wear out when used for a long time, which reduces the clamping effect of the lathe clamp on the object and affects the fixation of the object, which may cause the object to fall. For this reason, we provide a lathe clamp with an anti-fall function. Utility Model Content

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a lathe clamp with an anti-drop function, including a lathe clamp 1, a clamp block 2 is slidably connected to the top of the lathe clamp 1, and a fixed component 3 and a movable component 4 are arranged on the top of the clamp block 2. When the fixed rod 43 slides, the sliding block 42 will be pulled to slide inside the fixed block 41, thereby driving the clamping rod 45 and the sliding rod 46 to slide toward a position close to the sliding block 44. When the sliding block 44 slides, the clamping block 48 will be driven to slide in the sliding position of the sliding rod 46, and the movable component 4 includes: a fixed block 41, a sliding block 42, a fixed rod 43, a sliding block 44, a clamping rod 45, a sliding rod 46, a fixed spring 47, a clamping block 48, a fixed plate 49, a movable rod 410, and a pressing block 411.

[0023] The fixing block 41 is fixedly mounted on the top of the clamping block 2, and a sliding block 42 is slidably connected inside the fixing block 41. A fixing rod 43 is hinged on the surface of the sliding block 42, and a sliding block 44 is hinged at the bottom of the fixing rod 43. The sliding block 44 is slidably connected to the top of the clamping block 2. A clamping rod 45 is fixedly mounted on the top of the sliding block 42, and a sliding rod 46 is slidably connected inside the clamping rod 45. A fixing spring 47 is fixedly mounted on the surface of the sliding rod 46, and the fixing spring 47 is fixedly mounted on the outer side of the clamping rod 45. A clamping block 48 is hinged on the top of the sliding rod 46. A fixing plate 49 is fixedly mounted on the top of the clamping block 2, and a movable rod 410 is slidably connected inside the fixing plate 49. The movable rod 410 is fixedly mounted on the surface of the sliding block 44, and a pressing block 411 is fixedly mounted on the surface of the movable rod 410, so as to clamp the object to prevent the object from falling due to the wear of the clamping block 2, thereby improving the protection of the object and the clamping stability when the lathe fixture 1 is in use.

[0024] The fixing assembly 3 includes: an insertion rod 31, the insertion rod 31 is fixedly installed on the inner side of the pressing block 411, a limiting rod 32 is hinged on the surface of the insertion rod 31, one end of a torsion spring 33 is fixedly installed on the inner side of the limiting rod 32, and the other end of the torsion spring 33 is fixedly installed on the surface of the insertion rod 31. When the pressing block 411 moves, it will also drive the insertion rod 31 to slide toward the direction close to the fixing plate 49. When the insertion rod 31 slides, it will penetrate the fixing plate 49. When the insertion rod 31 penetrates the fixing plate 49, the fixing plate 49 will resist the limiting rod 32 on the surface of the insertion rod 31. After the insertion rod 31 penetrates the fixing plate 49, the limiting rod 32 It will reset under the action of the torsion spring 33, and thus be clamped on the outside of the fixed plate 49 for limiting, thereby enhancing the practicality and stability of the lathe fixture 1. There are three groups of clamping blocks 48, and the heights of the three groups of clamping blocks 48 are not uniform, so objects of different heights can be clamped. Holes 491 are provided on the surface of the fixed plate 49, and the insertion rod 31 can be used to penetrate the fixed plate 49 for restriction. A groove 4100 is provided on the surface of the fixed block 41, which can drive the sliding block 42 to slide inside the fixed block 41. The slide groove 20 on the top of the clamping block 2 can drive the slider 44 to slide on the top of the clamping block 2.

[0025] When the lathe clamp 1 is in use, the object can be clamped by sliding the clamp block 2 on the top of the lathe clamp 1. When the clamp block 2 is worn out after long-term use, the pressing block 411 can be manually pressed to drive the movable rod 410 to slide inside the fixed plate 49 toward the center point of the clamp block 2. When the movable rod 410 slides, it will drive the slider 44 to slide. When the slider 44 slides, it will drive the fixed rod 43 to slide toward one end close to the slider 44. When the fixed rod 43 slides, it will pull the sliding block 42 to slide inside the fixed block 41, thereby driving the clamping rod 45 and the sliding rod 46 to slide toward the direction close to the slider 44. When the slider 44 slides, it will drive the clamping block 48 to slide in the same sliding direction as the sliding rod 46, thereby clamping the object, preventing the wear of the clamp block 2 from causing the object to fall, thereby improving the protection of the object and the clamping stability when the lathe clamp 1 is in use.

[0026] When the pressing block 411 moves, it will also drive the insertion rod 31 to slide toward a position close to the fixed plate 49. When the insertion rod 31 slides, it will penetrate the fixed plate 49. When the insertion rod 31 penetrates the fixed plate 49, the fixed plate 49 will contact the limiting rod 32 on the surface of the insertion rod 31. After the insertion rod 31 penetrates the fixed plate 49, the limiting rod 32 will be reset under the action of the torsion spring 33, thereby being clamped on the outer side of the fixed plate 49 for limiting, thereby enhancing the practicality and stability of the lathe clamp 1.
