[0016] The technical solution in the embodiments of the present application is as follows to solve the above technical problem:
[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in combination with the drawings of the specification and specific embodiments.
[0018] A linear guide rail detection device, as shown in Figs. 1, 2, 3 and 4, comprises a T-shaped support plate 1, a U-shaped clamping plate 2 for supporting the linear guide rail, a moving device 3 for driving the U-shaped clamping plate 2 to move, and a positioning mechanism 4 for fixing the linear guide rail. The moving device 3 is arranged on the top plate of the T-shaped support plate 1. The moving end of the moving device 3 is provided with two groups of symmetrically arranged U-shaped clamping plates 2. The moving device 3 at the moving end works to drive the two groups of U-shaped clamping plates 2 to simultaneously slide close to each other or simultaneously slide away from each other. The top end of the U-shaped clamping plate 2 is provided with a plurality of groups of positioning mechanisms 4 arranged in a straight line array. The bottom plate of the T-shaped support plate 1 is vertically provided with a scale line 11.
[0019] The positioning mechanism 4 comprises a first threaded handle 41, a positioning plate 42 for abutting against the linear guide rail, and a first threaded rod 43 screwed to the top end of the U-shaped clamping plate 2. The first threaded handle 41 is arranged at the top end of the first threaded rod 43. The positioning plate 42 is arranged at the bottom end of the first threaded rod 43.
[0020] The moving device 3 comprises a moving block 31, a second threaded rod 32 for driving the moving block 31 to move, a bearing seat 33 arranged at both ends of the second threaded rod 32, and dovetail slide rails 34 for limiting the sliding of the moving block 31. The top plate of the T-shaped support plate 1 is provided with two groups of symmetrically arranged dovetail slide rails 34. The second threaded rod 32 is screwed with two groups of symmetrically arranged moving blocks 31. The two groups of moving blocks 31 are slidingly connected to the two groups of dovetail slide rails 34. The two groups of bearing seats 33 are arranged on the top plate of the T-shaped support plate 1.
[0021] The positioning mechanism 4 further comprises a rubber pad 44. The rubber pad 44 is arranged on the positioning plate 42.
[0022] In the linear guide rail detection device of the embodiment, one end of the second threaded rod 32 is provided with a second threaded handle 321. The second threaded rod 32 is screwed with two groups of symmetrically arranged moving blocks 31. The two groups of moving blocks 31 are slidingly connected to two groups of dovetail slide rails 34. The two groups of bearing seats 33 are arranged on the top plate of the T-shaped support plate 1.
[0023] The U-shaped clamping plate 2 is provided with a plurality of groups of linear array arranged damping pads 21 on one side for supporting the linear guide rail.
[0024] The device body is a T-shaped support plate 1, the top plate of which is installed with a moving device 3, and the surface of the bottom plate is provided with vertical scale lines 11 for quickly positioning and measuring the position deviation of the linear guide rail. The moving device 3 includes two symmetrical dovetail slide rails 34, a double-head reverse threaded second threaded rod 32 and two groups of moving blocks 31. The second threaded rod 32 is fixed on the top plate of the T-shaped support plate through bearing seats 33 at both ends, and the two symmetrical moving blocks 31 are in sliding connection with the dovetail slide rails 34 and are driven to move synchronously close to or away from each other by rotating the second threaded handle 321, so as to realize the symmetrical adjustment of the two groups of U-shaped clamping plates 2. The U-shaped clamping plates 2 are fixed on the moving blocks 31, and a plurality of groups of linearly arranged damping pads 21 are arranged on the inner side surfaces of the U-shaped clamping plates 2 for buffering the clamping force and protecting the surface of the guide rail. A plurality of positioning mechanisms 4 are installed at the top end of each U-shaped clamping plate 2, including a first threaded rod 43, a first threaded handle 41 and a positioning plate 42 at the bottom. A rubber pad 44 is bonded below the positioning plate 42, and the pressure of each positioning point can be individually adjusted by rotating the handle, so as to adapt to the local uneven area of the guide rail.
[0025] When the linear guide rail is fixed and detected: the two groups of U-shaped clamping plates 2 are synchronously moved to adapt to the length of the linear guide rail by rotating the second threaded handle 321, then the linear guide rail is placed between the two groups of adjusted U-shaped clamping plates 2, then a plurality of positioning mechanisms 4 are selected for local fine adjustment, the rubber pad 44 is in flexible contact with the top surface of the guide rail to avoid scratching, at this time the linear guide rail can be effectively and stably fixed. The installation deviation of the guide rail is quickly read through the scale lines 11 of the bottom plate of the T-shaped support plate, and the precision measurement of straightness, parallelism and the like is completed in combination with the detection instrument.
[0026] Due to the adoption of the T-shaped support plate 1, the U-shaped clamping plate 2, the moving device 3 and the positioning mechanism 4, the symmetrical U-shaped clamping plate 2 can be driven by the double-end reverse threaded rod, which can adapt to different lengths of linear guide rails and break through the size limitation of traditional fixed clamps. Multiple independent positioning mechanisms 4 support local fine adjustment, which can compensate for local size differences or deformation of the guide rail and improve clamping stability. The rubber pad 44 at the bottom of the positioning plate 42 and the damping pad 21 of the U-shaped clamping plate 2 form double buffering, which avoids direct contact between the threaded rod and the surface of the guide rail, prevents scratches or indentations, and ensures the quality of later processing. The scale line 11 on the bottom plate of the T-shaped support plate 1 cooperates with the symmetrical clamping structure to quickly locate the center line of the guide rail and intuitively read the installation deviation, reducing the manual calibration time. The dovetail slide rail 34 cooperates with the moving block 31 to ensure the straightness of the clamping plate movement and avoid skewing errors. The second threaded handle 321 is integrated on the outside of the moving device 3, and the width adjustment can be completed with one hand; the first threaded handle 41 adopts anti-slip design, which is convenient for quick screwing and positioning. The dovetail slide rail 34 and the T-shaped support plate 1 are designed in an integrated manner to enhance the anti-twisting ability and ensure that the device does not deform during detection, which is suitable for high-precision detection scenarios. The device solves the problems of poor adaptability, easy damage to the guide rail and complicated operation of traditional detection devices, and is especially suitable for efficient detection of multi-batch and large-size span linear guide rails.
