Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool technology, and in particular relates to a flatness detection device for linear guide rail production in CNC machine tools. Background Technology

[0002] Linear guides, also known as linear guides, are used to support and guide moving parts, enabling them to reciprocate linearly in a given direction. The design and manufacture of these guides aim to ensure that moving parts can operate in a low-friction, high-stability environment, thereby improving the efficiency and precision of the entire mechanical system. However, the straightness and flatness of linear guides have an extremely important impact on both the precision of mechanical manufacturing and installation, as well as on extending the service life of machines.

[0003] However, in the existing linear guide inspection process, the linear guide usually has multiple planes that need to be inspected, and the existing devices are not convenient to adjust according to the shape of the linear guide, resulting in low inspection efficiency and unreliable inspection accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a flatness testing device for linear guide rail production in CNC machine tools. By setting up a testing mechanism and adjusting it in multiple directions, the testing head can be positioned on different planes of the guide rail to perform multi-directional testing, which greatly improves the testing efficiency and effect. This solves the problem that in the existing linear guide rail testing process, the linear guide rail usually has multiple planes that need to be tested, and the existing devices are not convenient to adjust according to the shape of the linear guide rail, resulting in low testing efficiency and inability to guarantee testing accuracy.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a flatness detection device for linear guide rail production in CNC machine tools, including a support platform and a detection guide rail, wherein a detection mechanism is provided on the support platform;

[0007] The testing mechanism includes two fixed seats slidably connected to the top surface of the support platform. Each fixed seat has a slide rail fixedly connected to its top surface. Each slide rail has a slider slidably connected to its outer wall. Each slider has an electric push rod fixedly connected to its top surface. Each electric push rod has a fixed ring fixedly connected to its output end. Each fixed ring has an electric push rod 2 fixedly connected to its inner wall. Each electric push rod 2 has an adjusting rod fixedly connected to its output end. Each adjusting rod has a retaining ring slidably connected to its outer wall. Each retaining ring has a dial indicator fixedly connected to its outer wall. Each retaining ring has a threaded rod threaded onto its upper thread, extending into the retaining ring and contacting the adjusting rod.

[0008] Each of the two fixed seats is provided with a cleaning mechanism on one side that is close to each other. The cleaning mechanism includes a connecting plate that is fixedly connected to the two sliders on the side that is close to each other.

[0009] Furthermore, a second fixed base is fixedly connected to the top surface of the support platform, a detection guide rail is placed on the second fixed base, and a bolt is threadedly connected between the detection guide rail and the second fixed base. Both dial indicators are equipped with detection heads, and both detection heads are in contact with the detection guide rail.

[0010] Furthermore, four fixing plates are fixedly connected to the top surface of the support platform, and a bidirectional threaded rod is rotatably connected between two corresponding fixing plates. A sliding rod is fixedly connected between the other two fixing plates, and a handle is fixedly connected to the outer wall of the bidirectional threaded rod.

[0011] Furthermore, the two fixed seats are threaded onto the outer wall of the bidirectional threaded rod, and the two fixed seats are symmetrically arranged on the top of the support platform with the detection guide rail as the central axis. The slide rod passes through the two fixed seats, and the two fixed seats and the slide rod are slidably connected.

[0012] Furthermore, racks are fixedly connected to the sides of the two fixed seats that are close to each other, and rotating rods pass through the two connecting plates, with the two connecting plates rotatably connected to the two rotating rods respectively.

[0013] Furthermore, soft brushes are fixedly connected to the outer walls of both rotating rods, gears are fixedly connected to the outer walls of both rotating rods, the two gears mesh with the two racks respectively, the two soft brushes are in contact with the detection guide rails, and the two dial indicators are located to the right of the two soft brushes respectively.

[0014] This utility model has the following beneficial effects:

[0015] 1. With a detection mechanism, after adjusting the angle of the dial indicator using the sliding retaining ring, the knob on the threaded rod can be rotated to screw the threaded rod into the retaining ring and into contact with the adjusting rod, thus fixing the dial indicator to the outer wall of the adjusting rod. Electric push rod one and electric push rod two work together to further fine-tune the height and position of the dial indicator. With the assistance of the sliding rod, when the handle is turned to rotate the bidirectional threaded rod, the two fixed seats on the bidirectional threaded rod move closer or further apart along the sliding rod, causing the detection heads on the two dial indicators to contact the front and rear sides of the detection guide rail respectively. At this time, the two sliders can be manually pulled to slide on the guide rail, thus allowing the surface flatness of the detection guide rail of the two dial indicators to be detected. Through multi-directional adjustment, the detection heads can be positioned on different planes of the detection guide rail for multi-directional detection, greatly improving the detection efficiency and effect.

[0016] 2. By setting up a cleaning mechanism, before testing the test guide rail, the distance between the two fixed seats can be adjusted according to the contact surface between the soft brush and the test guide rail. This allows the test guide rail to be cleaned by adhering to its surface. During the manual dragging of the slider to move the test guide rail, the connecting plate will move synchronously. The two racks and gears mesh, causing the rotating rod and soft brush on the connecting plate to rotate during the movement. This allows the rotating soft brush to clean the surface of the test guide rail in advance, preventing dust particles from remaining on the surface of the test guide rail and causing inaccurate test results.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] Please see Figure 1-5 As shown, this utility model is a flatness detection device for linear guide rail production in CNC machine tools, including a support platform 1 and a detection guide rail 4, and a detection mechanism 2 is provided on the support platform 1;

[0028] The testing mechanism 2 includes two fixed seats 21 slidably connected to the top surface of the support platform 1. Each fixed seat 21 has a slide rail 22 fixedly connected to its top surface. Each slide rail 22 has a slider 23 slidably connected to its outer wall. Each slider 23 has an electric push rod 24 fixedly connected to its top surface. Each electric push rod 24 has a fixed ring 25 fixedly connected to its output end.

Each retaining ring 28 has a threaded rod 29 threadedly connected to its upper thread. The threaded rod 29 extends into the retaining ring 28 and contacts the adjusting rod 27. A fixed seat 296 is fixedly connected to the top surface of the support platform 1. A testing guide rail 4 is placed on the fixed seat 296. The testing guide rail 4 and the fixed seat 296 are threaded together. The support platform 1 is connected by bolts 41. Each of the two dial indicators 291 is equipped with a test head 2911, which is in contact with the test guide rail 4. Four fixing plates 292 are fixedly connected to the top surface of the support platform 1. A bidirectional threaded rod 293 is rotatably connected between two corresponding fixing plates 292. A slide rod 295 is fixedly connected between the other two fixing plates 292. A handle 294 is fixedly connected to the outer wall of the bidirectional threaded rod 293. Two fixing seats 21 are threaded onto the outer wall of the bidirectional threaded rod 293. The two fixing seats 21 are symmetrically arranged on the top of the support platform 1 with the test guide rail 4 as the central axis. The slide rod 295 passes through the two fixing seats 21. The two fixing seats 21 and the slide rod 295 are slidably connected. By setting up the test mechanism 2, the test head 2911 can be located on different planes of the test guide rail 4 to perform multi-directional test on the test guide rail 4, which greatly improves the efficiency and effect of the test.

[0029] Cleaning mechanisms 3 are provided on the adjacent sides of the two fixed seats 21. Each cleaning mechanism 3 includes a connecting plate 31 fixedly connected to the adjacent sides of the two sliders 23. A rack 32 is fixedly connected to the adjacent sides of the two fixed seats 21. A rotating rod 33 passes through each of the two connecting plates 31, and the two connecting plates 31 are rotatably connected to the two rotating rods 33 respectively. Soft brushes 35 are fixedly connected to the outer walls of the two rotating rods 33, and gears 34 are fixedly connected to the outer walls of the two rotating rods 33 respectively. The two gears 34 mesh with the two racks 32 respectively. The two soft brushes 35 are connected to the detection guide... The rails 4 are in contact with each other, and the two dial indicators 291 are located on the right side of the two soft brushes 35 respectively. By setting the cleaning mechanism 3, the slider 23 is manually dragged to move during the detection of the test rail 4, which will drive the connecting plate 31 to move synchronously. The two racks 32 mesh with the gears 34, so that the rotating rod 33 and the soft brushes 35 on the connecting plate 31 rotate during the movement. This allows the rotating soft brushes 35 to clean the surface of the test rail 4 in advance, so as to avoid the inaccurate test results caused by dust particles remaining on the surface of the test rail 4 during the test.

[0030] One specific application of this embodiment is as follows: The dial indicator 291 is a length measuring instrument that converts general linear displacement linear motion into pointer rotational motion through gears or levers, and then reads the value on the dial. The dial indicator 291 is a widely used indicating measuring tool in precision measurement. It belongs to the category of comparative measuring tools and can only measure relative values, not absolute values. It is mainly used to check the shape and position errors of workpieces (such as roundness, flatness, perpendicularity, circular runout, etc.) and is also often used for the precision alignment of workpieces.

[0031] With the detection mechanism 2 in place and multiple bolts 41 working together, the detection guide rail 4 can be fixed to the top surface of the fixed base 296. The electric push rod 24 can drive the fixed ring 25 to move up or down, and the electric push rod 26 can drive the adjusting rod 27 and the dial indicator 291 on the adjusting rod 27 to move telescopically. After the sliding retaining ring 28 adjusts the angle of the dial indicator 291, the knob on the threaded rod 29 can be rotated to screw the threaded rod 29 into the retaining ring 28 and into contact with the adjusting rod 27, thereby fixing the dial indicator 291 to the outer wall of the adjusting rod 27. The electric push rod 24 and the electric push rod 26 work together to further finely adjust the height and position of the dial indicator 291. After adjustment, with the cooperation of the slide bar 295, when the rotating handle 294 drives the bidirectional threaded rod 293 to rotate, it will drive the two fixed seats 21 on the bidirectional threaded rod 293 to move closer or further apart along the slide bar 295, so that the detection heads 2911 on the two dial indicators 291 contact the front and rear sides of the detection guide rail 4 respectively. At this time, the two sliders 23 can be manually pulled to slide on the slide rail 22, so that the surface flatness of the detection guide rail 4 of the two dial indicators 291 can be detected. Through multi-directional adjustment, the detection heads 2911 can be located on different planes of the detection guide rail 4 to perform multi-directional detection of the detection guide rail 4, which greatly improves the detection efficiency and detection effect.

[0032] By setting up the cleaning mechanism 3, before testing the test guide rail 4, the distance between the two fixed seats 21 can be adjusted according to the contact surface between the soft brush 35 and the test guide rail 4, so that the test guide rail 4 can be cleaned by adhering to its surface. During the process of manually dragging the slider 23 to move the test guide rail 4, the connecting plate 31 will move synchronously. The two racks 32 and the gear 34 mesh, so that the rotating rod 33 and the soft brush 35 on the connecting plate 31 rotate during the movement. This allows the rotating soft brush 35 to clean the surface of the test guide rail 4 in advance, avoiding inaccurate test results due to dust particles remaining on the surface of the test guide rail 4 during the test.
