Description

[Technical field]

[0001] The invention relates to a sliding door opening and closing life testing device. [Background technology]

[0002] There is currently a way to test the life of a shower room sliding door, which uses a traditional tester to apply force to the sliding door through the circular motion of the motor, so that the sliding door can automatically move back and forth, thereby testing the life of the sliding door. Because different sliding doors have different strokes, the existing tester cannot make the sliding door reach the extreme opening and closing positions during the test due to its structural limitations, and cannot perform a full stroke test of the overall structure of the sliding door, resulting in an inability to test the life of the overall structure of the sliding door. The traditional shower room sliding door opening and closing life tester has the following disadvantages: 1) It is impossible to perform a full stroke test of the sliding door; 2) The test force is constant and cannot be set individually; 3) There is no failure alarm, and accurate test data cannot be obtained. [Summary of the invention]

[0003] The technical problem to be solved by the present invention is to provide a sliding door opening and closing life test device capable of performing full stroke testing.

[0004] The object of the present invention is achieved in that:

[0005] A sliding door opening and closing life test device comprises a frame, a slide rail arranged on the frame, a test module slidably arranged on the slide rail and a driving device driving the test module to reciprocate on the slide rail, the test module is provided with a clamping assembly driving the sliding door to move synchronously with the test module, the test module is also provided with a force sensor for detecting whether the sliding door is opened and closed in place and a counter for detecting the number of times the sliding door is opened and closed, the force sensor is electrically connected to the driving device to control the driving device to drive in reverse when the force sensor detects that the sliding door is opened and closed in place so that the test module drives the sliding door to move in reverse.

[0006] The present invention adopts the above-mentioned structure, and the driving device can drive the test module to reciprocate on the slide rail, thereby driving the sliding door to reciprocate between its open extreme position and closed extreme position, thereby realizing the full stroke test of the sliding door, and then testing the life of the overall structure of the sliding door and obtaining accurate test data.

[0007] As described above, a sliding door opening and closing life test device, the test module includes a test support, a slider arranged on the back of the test support and slidably connected to the slide rail, and a slide slidably arranged at the front of the test support, the clamping assembly is arranged on the slide, the force sensor is arranged on one side of the test support, the driving device drives the slider to reciprocate along the slide rail, and the sliding door moves synchronously with the test module under the drive of the clamping assembly. When the force sensor detects that the thrust or pull force reaches a predetermined value, it proves that the sliding door has moved to the extreme position of opening or closing. At this time, the driving device is controlled to drive in reverse so that the test module drives the sliding door to move in the reverse direction, and this reciprocating cycle is repeated.

[0008] As described above, a sliding door opening and closing life test device is provided with a linear guide rail in the front part of the test support, the slide is slidably connected to the linear guide rail, one end of the force sensor is fixedly connected to the test support and the other end is fixedly connected to the side of the slide rail. When the sliding door moves to the extreme position of opening or closing, the sliding door stops moving. At this time, the driving device continues to drive the test support to continue to slide along the slide rail so that the slide can slide with a micro-displacement relative to the linear guide rail, thereby squeezing or stretching the force sensor. When the force sensor detects that the thrust or pull reaches the preset reversing value, the driving device is controlled to drive in reverse so that the test module drives the sliding door to move in the opposite direction, and this cycle is repeated.

[0009] In the sliding door opening and closing life test device as described above, the clamping assembly is a clamping block arranged on both sides of the sliding seat and capable of clamping the sliding door handle on the sliding door, thereby driving the sliding door to move synchronously when the test module slides relative to the slide rail.

[0010] As described above, in a sliding door opening and closing life test device, the driving device is a driving cylinder whose output end is fixedly connected to the test support, and the force sensor is a precision force sensor. When the sliding door has reached the end of its life, it becomes "stuck". At this time, the sliding door stops moving and causes the slide to slide relative to the linear guide rail. At this time, the thrust or pull of the test support on the force sensor increases sharply to a predetermined failure value. At this time, it is determined that the sliding door has reached the end of its life and the test is stopped.

[0011] In a sliding door opening and closing life test device as described above, the test module is also provided with a failure alarm electrically connected to the force sensor. When the thrust or pull detected by the force sensor reaches a predetermined failure value, it controls the drive device to stop working and triggers the failure alarm to issue an alarm reminder, thereby ensuring the accuracy of the test data.

[0012] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings, wherein:

[0013] Figure 1 It is a structural schematic diagram of the present invention;

[0014] Figure 2 It is a schematic diagram of the structure of the test module described in the present invention. [Specific implementation method]

[0015] A sliding door opening and closing life test device comprises a frame 1, a slide rail 2 arranged on the frame 1, a test module 3 slidably arranged on the slide rail 2 and a driving device 4 driving the test module 3 to reciprocate on the slide rail 2, the test module 3 is provided with a clamping assembly 31 driving the sliding door to move synchronously with the test module 3, the test module 3 is also provided with a force sensor 32 for detecting whether the sliding door is opened and closed in place and a counter for detecting the number of opening and closing times of the sliding door (the counter is of conventional design and is not shown in the figure), the force sensor 32 is electrically connected to the driving device 4 to control the driving device 4 to drive in reverse when the force sensor 32 detects that the sliding door is opened and closed in place so that the test module 3 drives the sliding door to move in reverse.

[0016] The test module 3 includes a test support 301, a slider 302 arranged at the back of the test support 301 and slidably connected to the slide rail 2, and a slide 303 slidably arranged at the front of the test support 301, the clamping assembly 31 is arranged on the slide 303, and the force sensor 32 is arranged on one side of the test support 301.

[0017] A linear guide 304 is provided at the front of the test support 301 , and the slide 303 is slidably connected to the linear guide 304 . One end of the force sensor 32 is fixedly connected to the test support 301 (fixedly connected via a connecting seat 305 ) and the other end is fixedly connected to the side of the slide 303 .

[0018] The clamping assembly 31 is a clamping block disposed on both sides of the sliding seat 303 and capable of clamping the sliding door handle 10 on the sliding door.

[0019] The driving device 4 is a driving cylinder whose output end is fixedly connected to the test support 301 or the slider 302. The force sensor 32 is a precision force sensor. The test force is controlled by the precision force sensor, which can adjust the reversing preset value and the failure preset value arbitrarily between 0-300N.

[0020] In order to realize failure alarm, the test module 3 is also provided with a failure alarm 5 electrically connected to the force sensor 32 .

[0021] When the present invention is used, the two clamping blocks of the clamping assembly 31 are clamped into the sliding door handle 10 of the sliding door, the driving device 4 is started, and the cylinder drives the slider 302 to reciprocate on the slide rail 2, thereby driving the test module 3 to reciprocate along the slide rail 2 as a whole. Driven by the clamping assembly 31, the sliding door moves synchronously with the test module 3. When the sliding door moves to the open or closed limit position, the sliding door stops moving. At this time, the driving device 4 continues to drive the slider 302 and the test support 301 to continue to slide along the slide rail 2 so that the slide 303 can slide with a micro-displacement relative to the linear guide rail 304, thereby squeezing or stretching the force sensor 32. When the force sensor 4 detects that the thrust or tension reaches the preset reversing value, it proves that the sliding door has moved to the open or closed limit position. At this time, the driving device 4 is controlled to drive in the reverse direction so that the test module 3 drives the sliding door to move in the reverse direction, and this reciprocating cycle is repeated, thereby realizing the continuous reciprocating movement of the sliding door between its open limit position and its closed limit position, during which the counter real-time counts the number of times the sliding door is opened and closed. When the life of the sliding door is exhausted, it becomes "stuck". At this time, the sliding door stops moving, and the driving device 4 continues to drive the slider 302 and the test support 301 to continue to slide along the slide rail 2 so that the slide 303 can slide slightly relative to the linear guide rail 304, thereby squeezing or stretching the force sensor 32. When the force sensor 4 detects that the thrust or pull force increases sharply to the predetermined failure value, it is determined that the life of the sliding door is exhausted and the driving device 4 is controlled to stop working. At the same time, the failure alarm 5 is controlled to sound an alarm and the counter is controlled to stop counting (corresponding control modules can be set between the force sensor 32 and the driving device 4, between the force sensor 32 and the failure alarm 5, and between the force sensor 32 and the counter for control). At this time, the data on the counter is the life data of the sliding door, thereby realizing the full stroke test of the sliding door, and then testing the life of the overall structure of the sliding door, and obtaining accurate test data.
