Description

Technical Field

[0001] This invention relates to a protective cover testing platform, belonging to the technical field of performance testing equipment for machine tool covers. Background Technology

[0002] Protective covers are devices used to protect the core components of machine tools, and their performance directly affects the accuracy and stability of the machine tool. Currently, most protective covers are directly assembled onto the machine tool without inspection. This leads to the following consequences: 1. They are prone to deformation, jamming, breakage, and detachment during use, directly damaging the machine tool guideways; 2. Poor sealing performance leads to wear on guideways and other components, reduced machining accuracy, and shortened machine tool life; 3. Protective covers are prone to vibration, abnormal noise, or deviation during high-speed operation, directly affecting normal machine tool processing; 4. Poor assembly accuracy of protective covers results in high wear, short service life, frequent maintenance, and reduced production efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a protective cover testing platform that simulates the running trajectory of the protective cover, tests various performance characteristics of the protective cover, improves the quality of the protective cover product, and reduces the production cost of the machine tool.

[0004] To solve the above problems, the specific technical solution of the present invention is as follows: A protective cover testing platform, comprising two fixed rails and two movable guide rails on a base, the two fixed rails being located on the outer side of the base and the movable guide rails being located on the inner side; a linear motor is provided in the two movable guide rails, the slider of the linear motor is connected to a vertically arranged drag body, the length of the drag body corresponds to the width of the base, and the bottom sides of the drag body are respectively slidably engaged with the fixed rails; a clamping device is provided at the end of the base, the clamping device clamps the end face fixed end of the protective cover, and the guide wheel inside the protective cover is guided and engaged with the top or side surface of the two movable guide rails.

[0005] The drag body is provided with several vertical T-slots, and the T-slot sliders set in the T-slots are connected to the end face of the protective cover.

[0006] Several sets of rotating lead screw devices are provided below the moving guide rail along the length of the base; the rotating lead screw device includes a rotating lead screw, a lead screw nut and a servo motor. The rotating lead screw is a left-right rotating lead screw with symmetrical rotation on both sides. A lead screw nut is connected to each rotation direction of the lead screw. The output end of the servo motor is connected to the rotating lead screw. The lead screw nuts on the same side of different sets jointly support a moving guide rail through the support base.

[0007] Two parallel inner guide rails are provided between the two moving guide rails, and the moving platform slides with the inner guide rails; the bottom surface of the moving platform engages with the slider of the linear motor.

[0008] A positioning frame for the detection equipment is provided on the upper surface of the mobile platform; a motion drag chain is provided on one side of one of the fixed guide rails, and a connecting bridge is provided between the motion drag chain and the mobile platform.

[0009] The end of the base is connected to a clamp via a bracket, and the clamp holds the middle of the fixed end face of the protective cover.

[0010] The back of the clamp is equipped with a damping buffer device, the position of which corresponds to the position of the linear motor.

[0011] The end of the movable guide rail is equipped with a side clamp, which clamps both sides of the fixed end face of the protective cover.

[0012] The protective shield testing platform of this application adopts the above structure and has the following advantages: 1. A linear motor is used to drive one side of the protective cover while the other side is fixed to complete the performance test of the protective cover; 2. The towing body is connected to one end of the protective cover and guided by a fixed track to ensure the smooth operation of the towing body; 3. The moving guide rail and the rotating screw device work together to achieve synchronous inward or outward movement along the center, thereby adapting to the width of different models of protective covers, and making the internal guide wheels cooperate with the moving guide rail to guide the movement, thus improving the stability of the protective cover during the movement process. 4. The base and the end of the moving guide rail are equipped with a center clamp and a side clamp, which can effectively position the fixed end of the protective cover. Attached Figure Description

[0016] like Figure 1 and Figure 2 As shown, a protective cover testing platform has the following structure: two fixed rails 3 and two movable guide rails 6 are provided on the base 1. The two fixed rails 3 are located on the outside of the base 1, and the movable guide rails 6 are located on the inside. A linear motor 4 is provided in the two movable guide rails 6. The slider of the linear motor 4 is connected to a vertically arranged drag body 2. The length of the drag body 2 corresponds to the width of the base 1, and the bottom sides of the drag body 2 are respectively slidably engaged with the fixed rails 3. A clamping device 7 is provided at the end of the base 1. The clamping device 7 clamps the end face fixed end of the protective cover, and the guide wheel inside the protective cover is guided and engaged with the top or side of the two movable guide rails 6.

[0017] Since the width of the protective cover varies with different models, the surface of the drag body 2 is provided with several vertical T-slots 2-1. The T-slots in the T-slots 2-1 are connected to the end face of the protective cover, thereby ensuring that the protective cover and the drag body 2 are connected to the corresponding T-slots 2-1, making it more adaptable.

[0018] Several sets of rotating lead screw devices 5 are provided below the movable guide rail 6 along the length of the base; such as Figure 3 As shown, the rotary screw device 5 includes a rotary screw 5-1, a lead screw nut 5-2, and a servo motor 5-3. The rotary screw 5-1 is a left- or right-handed screw with symmetrical rotation on both sides. Each direction of rotation of the screw is connected to the lead screw nut 5-2. The output end of the servo motor 5-3 is connected to the rotary screw 5-1. Different groups of lead screw nuts 5-2 on the same side jointly support a moving guide rail 6. When several groups of servo motors 5-3 are turned on simultaneously and run in the same direction, each rotary screw 5-1 simultaneously drives the moving guide rail 6 to move symmetrically inward or outward. The distance between the two moving guide rails 6 corresponds to the width of the protective cover.

[0019] Two parallel inner guide rails 8 are provided between the two moving guide rails 6, and the moving platform 9 slides with the inner guide rails 8; the bottom surface of the moving platform 9 engages with the slider of the linear motor 4. A detection equipment positioning frame 10 is provided on the upper surface of the moving platform 9; a motion drag chain 11 is provided on one side of one of the fixed guide rails 3, and a connecting bridge 12 is provided between the motion drag chain 11 and the moving platform 9. The weight of the detection equipment on the moving platform 9 is reduced by the inner guide rails 8, reducing the load on the linear motor 4 and ensuring its smooth operation.

[0020] The base 1 is connected to a central clamp 13 via a bracket at its end, which clamps the middle of the fixed end face of the protective cover. The movable guide rail 6 has side clamps 15 at its end, which clamp both sides of the fixed end face of the protective cover, ensuring the stability of the protective cover's end face during operation. A damping buffer device 14 is located on the back of the central clamp 13, and its position corresponds to that of the linear motor 4. This prevents the linear motor 4 from colliding with the central clamp 13 when unloaded.
