Description

Technical Field

[0001] This utility model relates to the field of slide rail testing, and in particular to a sliding performance testing device for aluminum slide rails. Background Technology

[0002] Drawer slides, also known as slide rails or slide tracks, are hardware connection components fixed to the cabinet body of furniture, allowing drawers or cabinet panels to move in and out. Drawer slides are suitable for connecting drawers in wooden and steel furniture such as cabinets, furniture, filing cabinets, and bathroom cabinets. During the manufacturing process of drawer slides, sliding tests are conducted on the produced slides to ensure their smooth operation.

[0003] A search revealed Chinese patent "A Mechanical Slide Rail Body Testing Platform" (authorization announcement number CN220322689U). This utility model discloses a mechanical slide rail body testing platform, belonging to the technical field of slide rail body testing devices. It includes a testing platform with support legs installed on its bottom outer wall. The platform has a sliding groove and a fixing component, comprising a first motor, a bidirectional screw, and a fixing block. The first motor is screwed to the side wall of the testing platform. This utility model, by setting the fixing component, can clamp and fix the slide rail body, preventing it from shaking or misaligning during testing, thus affecting the testing accuracy. The second motor drives a rotating rod, which in turn moves a sliding plate back and forth, ultimately causing a slider to move back and forth on the slide rail body. This improves operational convenience and the uniformity of the slider's movement speed on the slide rail body, ensuring the accuracy of the measurement results.

[0004] The above-mentioned testing device can perform uniform speed testing on the slide rail body by sliding the sliding plate back and forth on the slide rail body. However, the following problems exist in the actual test: During the test, since the slide rails have different shapes and have grooves and dead corners, if there are impurities or dust particles in the slide rail, it will easily affect the smoothness of the test and cause inaccurate test results.

[0005] Therefore, an aluminum slide rail sliding performance testing device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an aluminum slide rail sliding performance testing device to solve the above problems, thereby improving the problem that the overall function of the testing device is relatively simple and cannot avoid the problem that dust particles affect the accuracy of the sliding performance test data.

[0008] A detection component is disposed below the drive end of the drive device and located on the surface of the slide rail body;

[0009] The detection component includes a connecting shell located below the drive end of the drive device. Inside the connecting shell and on the side near the slide rail body, there is a detection shell. A force sensor is installed in the detection shell. The force sensor detects contact with the surface of the slide rail body. The detection shell has air holes for dust removal from the slide rail body. A scale is installed in the middle of the connecting shell.

[0010] Preferably, the detection assembly further includes a pulley disposed in the connecting shell. A shaft is fixedly connected to the middle of the pulley, and both ends of the shaft are threaded. A cylinder is disposed on the outer side of the connecting shell.

The air pipe of the cylinder passes through the connecting shell and communicates with the detection shell. Through the pulley, shaft, cylinder, and piston plate, when the drive device moves the connecting shell left and right back and forth on the surface of the slide rail body for detection, the pulley can drive the shaft to rotate and cause the piston plate to move left and right back and forth on the surface of the shaft and in the cylinder, performing suction and exhaust movements in the cylinder to inject air into the detection shell and blow the gas through the air hole to the groove and dead corner of the slide rail body, which can blow away dust and impurity particles and prevent them from affecting the sliding detection operation.

[0011] Preferably, a through hole is provided in the middle of the connecting shell, and a bearing seat is slidably connected in the through hole. The bearing seat is disposed on the surface of the shaft, and a spring is fixedly connected to the upper part of the bearing seat. The upper end of the spring is fixedly connected to the inner wall of the through hole. Through the through hole, the bearing seat and the spring, the position compensation of the shaft can be performed when the pulley rolls to the bending position of the slide rail body.

[0012] Preferably, the inner wall of the through hole is provided with a sliding groove, and a slider is slidably connected in the sliding groove. The side of the slider near the bearing seat is fixedly connected to the bearing seat. By using the sliding groove and the slider, the bearing seat can be vertically limited.

[0013] Preferably, a movable plate is vertically slidably connected in the connecting shell above the pulley. The lower part of the movable plate fits the curvature of the pulley, and a scale is fixedly connected to the upper part of the movable plate. The upper end of the scale extends to the outside of the connecting shell. Through the movable plate and the scale, the scale ring can be raised according to the height of the pulley, so that it can be inspected by personnel and reworked if the slide rail body is irregular.

[0014] Preferably, the scale is fitted with a scale ring on its surface, a telescopic rod is fixedly connected to one side of the scale ring, a one-way valve is provided on the lower part of the surface of the telescopic rod, and the lower end of the telescopic rod is fixedly connected to the connecting shell.

[0016] The beneficial effects of this utility model are:

[0017] By setting up pulleys, shafts, cylinders, and piston plates in the detection assembly, when the drive device moves the connecting shell back and forth on the surface of the slide rail body for detection, the pulleys can drive the shaft to rotate and the piston plate can move back and forth on the surface of the shaft and in the cylinder body, performing air intake and exhaust movements in the cylinder body to inject air into the detection shell and blow the air through the air holes to the grooves and dead corners of the slide rail body, which can blow away dust and impurity particles and prevent them from affecting the sliding detection operation of the force sensor.

[0018] When the pulley rolls on the surface of the slide rail body, if it encounters an uneven or bent part of the slide rail body surface, the scale can be raised by the movable plate, and the height of the scale ring can be increased, so that subsequent personnel can check and rework the slide rail body. At the same time, it can also achieve the effect of flatness detection of the slide rail body, improving the overall practicality and functionality of the detection equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In practical implementation: such as Figure 1-6 As shown, an aluminum slide rail sliding performance testing device includes: a platform 1 and a drive device 2 disposed above it, and a slide rail body 3 to be tested is disposed on the platform 1.

[0028] Detection component 4 is located below the drive end of the drive device 2 and on the surface of the slide rail body 3;

[0029] Aluminum slide rails are widely used in various industrial and everyday products, such as mechanical transmission systems, furniture, automation equipment, and electronic equipment. Aluminum is chosen as the material for slide rails because of its advantages such as being lightweight, corrosion-resistant, and easy to process. In order to ensure the performance and reliability of aluminum slide rails, sliding performance testing is essential.

[0030] like Figure 2 , Figure 4 and Figure 6As shown, the detection assembly 4 includes a connecting shell 401 located below the drive end of the drive device 2. A detection shell 405 is located inside the connecting shell 401 and near the slide rail body 3. The detection shell 405 has an air hole 406 for dust removal from the slide rail body 3. A scale 414 is located in the middle of the connecting shell 401. A force sensor 419 is located in the detection shell 405, and the force sensor 419 contacts the surface of the slide rail body 3. The detection assembly 4 also includes a pulley 407 located in the connecting shell 401. A shaft 408 is fixedly connected to the middle of the pulley 407. Both ends of the shaft 408 are threaded. A cylinder 415 is located on the outside of the connecting shell 401. One end of the shaft 408 passes through the cylinder 415 and is threaded to a piston. The surfaces of plate 416 and shaft 408 are movably connected to cylinder 415 via bearings. Cylinder 415 is fitted to the outer surface of connecting shell 401. An air pipe is connected to the air outlet of cylinder 415. The air pipe of cylinder 415 passes through connecting shell 401 and connects to detection shell 405. A through hole 404 is provided in the middle of connecting shell 401. A bearing seat 409 is slidably connected in the through hole 404. The bearing seat 409 is provided on the surface of shaft 408. A spring 410 is fixedly connected to the upper part of bearing seat 409. The upper end of spring 410 is fixedly connected to the inner wall of through hole 404. A sliding groove 403 is provided in the inner wall of through hole 404. A slider 411 is slidably connected in the sliding groove 403. The side of slider 411 near bearing seat 409 is fixedly connected to bearing seat 409.

[0031] In practical use, the drive end of the drive device 2 first drives the force sensor 419 in the connecting housing 401 to move back and forth on the surface of the slide rail body 3 to perform sliding detection. When the connecting housing 401 moves, the pulley 407 will roll above the slide rail body 3. At this time, the shaft 408 in the pulley 407 will rotate with it. The piston plate 416 on the surface of the shaft 408 will move back and forth in the cylinder 415 along with the thread at the end of the shaft 408. When the piston plate 416 moves towards the pulley 407, the cylinder... The cylinder 415 is under negative pressure and is drawn into the cylinder 415 through the valve port. When the piston plate 416 moves away from the pulley 407, the gas in the cylinder 415 will be squeezed out into the detection shell 405 through the air pipe. Then the detection shell 405 can blow the gas into the groove of the slide rail body 3 through the air hole 406 to achieve the effect of blowing away dust. This can effectively prevent the detection shell 405 from being obstructed by particles or impurities when the connecting shell 401 drives the detection shell 405 to perform sliding tests on the surface of the slide rail body 3, thus affecting the overall test operation.

[0032] It should be noted that the drive device 2 consists of a housing, a motor, a threaded rod, a threaded sleeve, and a moving plate. The housing is set on the platform 1, the motor is located on the side of the housing, the threaded rod is located in the housing and one end of it is fixed to the output end of the motor, the threaded sleeve is threadedly connected to the surface of the threaded rod, and the moving plate is fixed to the surface of the threaded sleeve and one end of it is fixed to the top of the connecting shell 401. When performing the sliding test, the motor is first turned on, and the output end of the motor, through the threaded rod and the threaded sleeve, causes the moving plate to drive the connecting shell 401 to move back and forth. At this time, the force sensor 419 in the connecting shell 401 will displace on the surface of the slide rail body 3 and calculate the friction force, and perform the sliding test.

[0033] When force sensor 419 tests the friction between slider 411 and slide rail, it usually calculates the friction indirectly by measuring the force required for the detection shell 405 to move on the slide rail. Force sensor 419 is installed between detection shell 405 and slide rail body 3 to test the reaction force generated when detection shell 405 moves along slide rail body 3. The reaction force caused by friction is captured by force sensor 419, and the friction can be calculated. Based on the calculated data, it can be determined whether the overall sliding performance of slide rail body 3 is qualified.

[0034] Threads are provided on both ends of the shaft 408. The threads are the threads of a reciprocating lead screw, so the piston plate 416 can move back and forth when the shaft 408 rotates.

[0035] like Figure 4 and Figure 5 As shown, a movable plate 413 is vertically slidably connected to the connecting shell 401 above the pulley 407. The lower part of the movable plate 413 fits the curvature of the pulley 407. A scale 414 is fixedly connected to the upper part of the movable plate 413. The upper end of the scale 414 extends to the outside of the connecting shell 401. A scale ring 418 is fitted on the surface of the scale 414. A telescopic rod 417 is fixedly connected to one side of the scale ring 418. A one-way valve is provided on the lower part of the surface of the telescopic rod 417. The lower end of the telescopic rod 417 is fixedly connected to the connecting shell 401. A limit groove 402 is opened in the connecting shell 401. A limit block 412 is slidably connected in the limit groove 402. The side of the limit block 412 near the movable plate 413 is fixedly connected to the movable plate 413.

[0036] Because aluminum is lightweight, it is prone to deformation or bending, which can easily affect the movement path during sliding tests. When the pulley 407 rolls left and right above the slide rail body 3, if the slide rail body 3 is bent, the pulley 407 will be lifted up, and the movable plate 413 will lift the scale 414. At this time, the scale 414 will use friction to drive the scale ring 418 to rise, which makes it convenient for staff to check after the test and rework irregular slide rail bodies 3, achieving the effect of a single testing device to perform multiple testing operations.

[0037] When the scale ring 418 rises, the telescopic rod 417 extends accordingly. At this time, the one-way valve on the surface of the telescopic rod 417 will open and draw in external air. Since the one-way valve can only draw in air, when the telescopic rod 417 is extended to a certain height and stops extending, the telescopic rod 417 will be locked by the air pressure inside, so that the scale ring 418 is kept at the highest value of the rise. In this way, when the scale 414 falls, the scale ring 418 will not be pulled down and reset.

[0038] It should be noted that before the overall inspection, the staff needs to observe and record the position of the scale ring 418 on the scale 414. In this way, after the sliding performance test of the slide rail body 3, it is only necessary to compare the height of the scale ring 418 after the test with the original position of the scale ring 418 to find out whether the slide rail body 3 has a bending or deformation phenomenon.

[0039] Working principle: In actual use, the drive end of the drive device 2 first drives the force sensor 419 in the connecting shell 401 to move back and forth on the surface of the slide rail body 3 to perform sliding detection. When the connecting shell 401 moves, the pulley 407 will roll above the slide rail body 3. At this time, the shaft 408 in the pulley 407 will rotate with it. The piston plate 416 on the surface of the shaft 408 will move back and forth in the cylinder 415 along with the thread at the end of the shaft 408. When the piston plate 416 moves towards the pulley 407, the cylinder 415 is in a negative pressure state and air is drawn into the cylinder 415 through the valve port. When the piston plate 416 moves away from the pulley 407, the gas in the cylinder 415 will be squeezed out through the air pipe into the detection shell 405. Then the detection shell 405 can be opened through the air hole. 406 blows gas into the groove of the slide rail body 3 to achieve the effect of blowing away dust. When the pulley 407 rolls left and right above the slide rail body 3, if the slide rail body 3 is bent, the pulley 407 will be lifted up, and the movable plate 413 will lift the scale 414. At this time, the scale 414 will use friction to drive the scale ring 418 to rise. When the scale ring 418 rises, the telescopic rod 417 will stretch along with it. At this time, the one-way valve on the surface of the telescopic rod 417 will open and draw in external gas. Since the one-way valve can only draw in air by itself, when the telescopic rod 417 is stretched to a certain height and stops stretching, the telescopic rod 417 will be locked by its internal air pressure, so that the scale ring 418 is kept at the highest value of the lift, which can be convenient for the staff to check after the inspection.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
