Description

Technical Field

[0001] The utility model relates to the technical field of mechanical guide rail processing, in particular to a testing platform for mechanical guide rail production. Background Art

[0002] A guide rail refers to a device with grooves or ridges made of metal or other materials that can bear, fix, guide moving devices or equipment and reduce their friction. The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix machine parts, special equipment, instruments, etc. Guide rails, also known as slide rails, linear guides, and linear slides, are used in linear reciprocating motion situations. They have a higher rated load than linear bearings and can withstand a certain amount of torque. They can achieve high-precision linear motion under high loads. After production, guide rails usually need to be tested to understand the relevant data of the guide rails. However, traditional guide rail testing devices simply place the guide rails on the test table during the test process, and do not limit and fix the guide rails. As a result, the guide rails are prone to shaking and misalignment during the test, thereby affecting the test accuracy of the guide rails.

[0003] In order to solve the above problems, the utility model patent with authorization announcement number CN220322689U discloses a mechanical guide rail testing platform. The device is equipped with a second motor, which can drive the rotating rod to rotate through the operation of the second motor, and then drive the sliding plate to move back and forth, and finally drive the slider to move back and forth on the guide rail, thereby improving the operational convenience and the uniformity of the slider's moving speed on the guide rail, and ensuring the accuracy of the measurement results.

[0004] However, the device only fixes the linear guide rail from the left and right sides through pressure plates, and the fixing effect is limited. The guide rail may still deviate during testing, which may affect the accuracy of the test and cannot meet the use requirements well. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: See Figures 1 to 4 A test platform for the production of mechanical guide rails includes: a test bench 1, an electronic micrometer 11; a moving mechanism 2, installed on the test bench 1, for driving the slider on the guide rail to move; a clamping mechanism 3, installed on the moving mechanism 2, for fixing the slider to the moving mechanism 2; a fixing mechanism 4, installed on the test bench 1, for fixing the guide rail on the test bench, the fixing mechanism 4 includes a fixing component 1 and a fixing component 2, the fixing component 1 fixes the guide rail from the left and right sides, and the fixing component 2 fixes the guide rail from the front and back sides; in this embodiment, the electronic micrometer 11 is installed on the clamping mechanism 3, and the lower end of the electronic micrometer 11 is in contact with the upper end surface of the guide rail. The electronic micrometer 11 is an existing mature technology.

[0023] The fixing assembly 1 includes a pair of fixing seats 41 installed on the left and right sides of the test bench 1. Each fixing seat 41 is screwed with a fixing handwheel 42. The end of the fixing handwheel 42 passes through the fixing seat 41 and is rotatably mounted with a fixing top plate 44. A fixing guide rod 43 is also slidably inserted on the fixing seat 41, and the fixing guide rod 43 is fixedly connected to the fixing top plate 44.

[0024] The second fixed component includes a fixed slide groove 441 opened on the opposite side of the fixed top plate 44, and a fixed screw 442 is rotatably installed in the fixed slide groove 441. The threads on both sides of the fixed screw 442 have opposite rotation directions. A pair of fixed slides 46 are also threadedly mounted on the fixed screw 442, and each of the fixed slides 46 is installed with a fixed block 47. The fixed slides 46 are slidably installed in the fixed slide groove 441, and a turning handle 45 is also rotatably installed on the front side of the fixed top plate 44. The shaft end of the turning handle 45 is drivingly connected to the end of the fixed screw 442, and a fixed pressure plate 48 is also installed on the fixed top plate 44.

[0025] The working principle of the present invention is as follows: when in use, the guide rail to be tested is placed on the test bench 1, and then the fixed hand wheels 42 on both sides are rotated, and the fixed top plates 44 on both sides are pushed closer to each other through the fixed hand wheels 42, thereby clamping the guide rail. At this time, the fixed pressure plate 48 presses the guide rail, and then the turning handle 45 is rotated, and the turning screw 442 is driven to rotate through the turning handle 46, so that the fixing blocks 47 on the front and rear sides are close to each other, so that the fixing blocks 47 extend into the grooves on the front and rear sides of the guide rail and clamp the guide rail, thereby achieving the fixation of the guide rail. The fixing in multiple directions can improve the fixing effect of the guide rail, effectively prevent the guide rail from deflecting during testing, and better meet the use requirements.

[0026] After the guide rail is fixed, the slider on the guide rail is fixed to the moving mechanism 2 by the clamping mechanism 3. Then, the slider is moved by the moving mechanism 2, and the electronic micrometer 11 moves synchronously to detect the horizontality of the upper end surface of the guide rail.

[0027] As a further solution, the moving mechanism 2 includes a pair of moving seats 21 installed on the test bench 1, and a moving screw 23 is rotatably installed between the moving seats 21. A moving motor 22 is also installed at the end of the moving seat 21. The output end of the moving motor 22 is drive-connected to the shaft end of the moving screw 23. A moving slide 24 is also threadedly mounted on the moving screw 23. The moving screw 23 is a reciprocating screw, which can realize the left and right reciprocating motion of the moving slide 24. In order to improve the stability of the movement of the moving screw 22, a moving slide 25 is also provided on the test bench 1. The moving slide 24 is slidably installed in the moving slide 25, and a mounting plate 241 is also fixed on the front side of the moving slide 24.

[0028] The working principle of the moving mechanism 2 is: when moving, the moving motor 22 is started, and the moving screw 23 is driven to rotate by the moving motor 22, thereby causing the moving slide 24 threadedly mounted on the moving screw 23 to move accordingly.

[0029] As a further solution, the clamping mechanism 3 includes a lifting assembly mounted on a mounting plate 241 and a clamping assembly mounted inside the lifting assembly. The lifting assembly includes a lifting electric push rod 31 mounted on the upper end of the mounting plate 241. The telescopic end of the lifting electric push rod 31 passes through the mounting plate 241 and is fixed with a lifting seat 33. A lifting guide rod 32 is also slidably inserted on the mounting plate 241. The lower end of the lifting guide rod 32 is fixedly connected to the upper end of the lifting seat 33. The lifting seat 33 is U-shaped.

[0030] The clamping assembly includes a clamping handwheel 34 threadedly mounted on the left side of the lifting seat 33, and a clamping plate 36 is rotatably mounted on the end of the clamping handwheel 34. A clamping guide rod 35 is also slidably inserted on the left side of the lifting seat 33, and the end of the clamping guide rod 35 is fixedly connected to the clamping plate 36.

[0031] The working principle of the clamping mechanism 3 is: when the slider on the guide rail needs to be fixed to the moving mechanism 2, the lifting electric push rod 31 extends, pushing the lifting seat 33 downward, and then the lifting seat 33 is sleeved on the slider. Then, the clamping handwheel 34 is rotated, and the clamping plate 36 is pushed by the clamping handwheel 34 to move the slider, and the slider can be clamped in cooperation with the lifting seat 33, thereby completing the fixing work.

[0032] As a further solution, the electronic dial gauge 11 is installed on the right side of the lifting seat 33.
