Description

Technical Field

[0001] This utility model relates to the field of CNC slider machining technology, specifically a CNC slider machining clamping fixture. Background Technology

[0002] CNC slider machining is a common and important machining process in the field of mechanical processing. The following details its aspects: Machining process flow and drawing analysis: First, carefully study the slider's design drawings to clarify its dimensional accuracy requirements (such as the length, width, thickness of each part, and related geometric tolerances), surface roughness requirements, material properties, and other key information. For example, for sliders used in high-precision molds, dimensional tolerances may be controlled within ±0.01mm, and surface roughness requirements may reach Ra0.8μm or even higher. Blank preparation: Select appropriate blank materials and forms based on the slider's size, shape, and batch size. Common blanks include forgings, castings, or directly selecting suitable profiles (such as rectangular steel blocks). For example, for sliders bearing large loads, forged blanks may be used to ensure dense internal structure and good mechanical properties.

[0003] Patent publication number "CN217143203U" discloses a utility model applicable to the field of clamping fixture technology, particularly relating to a CNC slider machining clamping fixture, comprising a worktable, a support base, a pneumatic telescopic rod, a mounting plate, and a clamp. The support base is connected to the surface of the worktable, the pneumatic telescopic rod is mounted on the support base, the mounting plate is disposed at one end of the pneumatic telescopic rod, and the clamp is mounted on the surface of the mounting plate. The CNC slider machining clamping fixture further includes: a debris cleaning structure disposed on the mounting plate for cleaning debris from the side of the slider before the clamp limits its position; and a debris collection structure disposed on the worktable for collecting debris from the worktable surface. This utility model, by providing a debris cleaning structure, can conveniently clean debris from the side of the slider before the clamp limits its position, thereby preventing debris from affecting the clamp's limiting effect on the slider, and thus improving the practicality of the fixture.

[0004] In the aforementioned patent, the existing fixture does not have a good centering function. In actual use, the CNC slider is prone to displacement when clamping, which affects the clamping effect. Furthermore, the clamping cannot be adjusted according to the size of the CNC slider, so a smaller CNC slider will affect the machining effect.

[0005] To address these issues, this invention provides a CNC slider machining clamping fixture. Utility Model Content

[0031] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1 to 4 This application provides a CNC slider machining clamping fixture, including a worktable 1. A clamping assembly 2 is fixedly installed on the top of the worktable 1, and an auxiliary assembly 3 is fixedly installed on the top of the clamping assembly 2. A centering assembly 4 is fixedly installed on the bottom of the worktable 1. The centering assembly 4 includes an electric push rod 41 and a lifting plate 42. The electric push rod 41 is fixedly installed on the bottom of the worktable 1. The lifting plate 42 is fixedly connected to the output end of the electric push rod 41. A U-shaped frame 43 is fixedly installed on the top of the lifting plate 42. A connecting rod 44 is hinged to the inner side wall of the U-shaped frame 43. A second U-shaped frame 45 is hinged to the top of the connecting rod 44. A centering plate 46 is fixedly installed on the top of the second U-shaped frame 45. A stabilizing groove 47 is provided at the bottom of the worktable 1. The centering plate 46 and the stabilizing groove 47 are slidably engaged.

[0033] In this embodiment, the electric push rod 41 is then turned on, which drives the lifting plate 42 to move upward. The lifting plate 42 then drives the connecting rod 44 to move, so that the connecting rod 44 can drive the centering plate 46 to slide inside the stabilizing groove 47. This also allows the centering plate 46 to center the CNC slider, so that it can be located in the center position and the clamping of it will be more stable.

[0034] Reference Figures 1 to 4 In one aspect of this embodiment, the clamping assembly 2 includes a clamping plate 21 and a fixing plate 22. The clamping plate 21 is fixedly installed on the top of the workbench 1, and the fixing plate 22 is fixedly installed on the top of the workbench 1. A threaded rod 23 is threadedly connected to one side of the fixing plate 22, and a clamping plate 24 is connected to one end of the threaded rod 23 via a bearing. The clamping assembly 2 also includes a stabilizing rod 25, which is fixedly installed on one side of the clamping plate 24 and slidably connected to the fixing plate 22. The clamping assembly 2 also includes a crank handle 26, which is fixedly connected to one end of the threaded rod 23. The auxiliary assembly 3 includes... The clamping plate 31 and the positioning rod 32 are respectively set on the top of the clamping plate 21 and the clamping plate 24. The positioning rod 32 is fixedly installed on the top of the clamping plate 21 and the clamping plate 24. The top of the clamping plate 31 is provided with a positioning groove 33, which is engaged with the positioning rod 32. The auxiliary component 3 also includes a screw 34, which is threaded to the top of the clamping plate 31. The top of the clamping plate 21 and the clamping plate 24 are respectively provided with screw holes 35, which are engaged with the screw holes 35. The auxiliary component 3 also includes a knob 36, which is fixedly connected to the top of the screw 34.

[0035] In this embodiment, the positioning groove 33 and the positioning rod 32 are first snapped together. Then, rotating the screw hole 35 can drive the screw rod 34 to be screwed together with the screw hole 35 to fix the clamping plate 31. After that, the smaller CNC slider can be placed on the top of the clamping plate 31 for auxiliary clamping, so that the small CNC slider also has a good clamping effect. Then, rotating the handle 26 can drive the threaded rod 23 to move on one side of the fixed plate 22 using the thread, so that the threaded rod 23 can drive the clamping plate 24 to cooperate with the clamping plate 21 to clamp the CNC slider. The clamping is simple and stable.

[0036] Working principle: First, the positioning groove 33 and the positioning rod 32 are snapped together. Then, rotating the screw hole 35 can drive the screw rod 34 to be screwed together with the screw hole 35 to fix the clamping plate 31. Then, the smaller CNC slider can be placed on the top of the clamping plate 31 for auxiliary clamping, so that the small CNC slider also has a good clamping effect. Then, turning the crank handle 26 can drive the threaded rod 23 to move on one side of the fixed plate 22 using the thread. This allows the threaded rod 23 to drive the clamping plate 24 to cooperate with the clamping plate 21 to clamp the CNC slider. The clamping is simple and stable.

[0037] Then, turning on the electric push rod 41 can drive the lifting plate 42 to move upward. The lifting plate 42 will then drive the connecting rod 44 to move, so that the connecting rod 44 can drive the centering plate 46 to slide inside the stabilizing groove 47. This also allows the centering plate 46 to center the CNC slider, so that it can be located in the center position and the clamping will be more stable.
