Description

Technical Field

[0001] The present application relates to the technical field of automobile handle detection equipment, and in particular to a buffer testing machine for automobile handles. Background Art

[0002] Car handles, also known as car roof handles, are used by passengers to hold on to maintain balance or support their bodies. Figure 1 The car handle includes a hand-held component for grasping and two connecting components for connecting the hand-held component with the car roof. The hand-held component is rotatably connected to the two connecting components, and the two connecting components are fixedly connected to the car roof.

[0003] To facilitate the use of the handle, the connection between the handpiece and the connector has a structure that enables the handpiece to automatically rotate and reset. Usually, the handpiece is stored in the car interior ceiling, and the passenger can rotate the handpiece to take it out and hold it as needed; when the passenger no longer needs to hold the handpiece, release the handpiece, and the handpiece will automatically rotate and reset. In order to prevent the handpiece from rotating and resetting too quickly and colliding with the car ceiling to produce noise, the structure that enables the handpiece to automatically rotate and reset also has a buffering effect, allowing the handpiece to slowly rotate and reset.

[0004] In the process of quality inspection of handles, the buffer speed of handles is also an important indicator. Handles need to maintain their buffer speed within a certain range in multiple tests before they can pass the quality inspection. However, manual operation is still commonly used in the buffer speed test of handles today. Operators are required to manually control the handle to rotate multiple times to collect data on its buffer speed, which has high labor costs and low test efficiency. Summary of the invention

[0005] In order to reduce labor costs and facilitate buffering tests on automobile handles, the present application provides a buffering testing machine for automobile handles.

[0006] The present application provides a buffer testing machine for automobile handles, which adopts the following technical solution:

[0009] A positioning device for fixing the handle, the positioning device is arranged on the mounting seat, the positioning device comprises a positioning member for fixing the connecting member and a first driving member for driving the positioning member to move, the positioning member is located in the mounting groove;

[0010] A driving device for driving the handle to rotate and reset, the driving device is also arranged on the mounting seat, the driving device includes a working component for driving the handpiece to rotate and a second driving component for providing power to the working component, the working component includes a working body, the working body is rotatably connected to the mounting seat, the rotation axis of the working body is parallel to the rotation axis of the handpiece, when the working body and the handpiece are against each other, the rotation of the working body drives the handpiece to rotate, and when the handpiece rotates to the extreme position, the working body is separated from the handpiece;

[0011] A detection device for collecting data, the detection device comprises a detection component for detecting a handle buffer time and a control component for recording and displaying data, the detection component is arranged on a mounting seat.

[0012] By adopting the above technical solution, after the handle is installed on the mounting seat, the positioning device fixes the position of the connecting piece, the driving device drives the hand piece to rotate, and the hand piece automatically rotates and retracts after rotating to the extreme position, and this cycle is repeated. At the same time, the detection device detects the time taken for the hand piece to automatically rotate and retract each time, thereby judging whether the buffer speed of the handle is qualified. There is no need to test the buffer speed of the handle by manpower, and the buffer testing machine has a high degree of automation, which can improve the efficiency of testing the buffer speed of the handle and facilitate buffer testing of automobile handles.

[0013] Optionally, the working component further includes two movable ends, which are respectively located at two ends of the working body, and the movable ends can move along the length direction of the working body.

[0016] By adopting the above technical solution, when the working component rotates and drives the handpiece to rotate, the wear between the abutment part and the handpiece can be reduced, and the impact of the friction between the abutment part and the handpiece can be reduced, so that when the handpiece rotates to the extreme position, the abutment part can be smoothly separated from the handpiece.

[0017] Optionally, it also includes a rotating device for controlling the rotation of the mounting seat, the rotating device includes a support seat and a rotating assembly for driving the mounting seat to rotate, the two ends of the rotating assembly are respectively fixedly connected to the support seat and the mounting seat, and the rotation axis of the mounting seat is parallel to the rotation axis of the working body.

The loading device includes a loading frame for holding the handles to be tested and a support frame for mounting and fixing the loading frame. A plurality of handles are neatly stacked inside the loading frame. An outlet for the handles to leave is provided at one end of the loading frame close to the mounting seat. When the mounting seat is rotated to a horizontal state, the outlet is aligned with the mounting groove in the vertical direction.

[0022] By adopting the above technical solution, the loading of the handle can be facilitated, thereby further improving the automation level of the buffer testing machine, saving the time required for loading the handle, and further accelerating the efficiency of the buffer test on the handle.

[0023] Optionally, the loading frame is slidably connected to the support frame, and the mounting seat rotates to drive the loading frame to slide. When the handle on the mounting seat is detected, there is a distance between the loading frame and the mounting seat; when the mounting seat rotates to a horizontal state, the connecting part of the handle in the loading frame closest to the mounting seat is located in the mounting groove.

[0024] By adopting the above technical solution, the loading of the handle can be further facilitated. The positioning device fixes the connector of the handle in the installation groove to complete the loading of the handle, which further saves the time required for loading the handle.

[0025] Optionally, a material unloading device is further included, which is located below the mounting seat and includes a first material unloading frame for containing handles that fail the test and a second material unloading frame for containing handles that pass the test.

[0026] By adopting the above technical solution, the buffer testing machine can conveniently separate and collect qualified and unqualified handles according to the test results. In a short period of time, the buffer testing machine can still automatically perform buffer tests on several handles without the supervision of operators, thereby making the use of the buffer testing machine more convenient.

[0027] Optionally, the first blanking frame is aligned with the mounting seat in the vertical direction, and the second blanking frame is located on one side of the first blanking frame. After the mounting seat rotates a certain angle, the handle can move along the mounting seat and fall into the second blanking frame.

The working body 511 is located in the clearance groove 34, and the working body 511 is rotationally connected to the mounting seat 3. The rotation connection position of the working body 511 and the mounting seat 3 is located in the middle of the working body 511. The second driving member 52 drives the working body 511 to rotate, and the rotation axis of the working body 511 is parallel to the rotation axis of the handpiece 11 fixedly installed on the mounting seat 3 at this time. In this embodiment, it is preferred that the second driving member 52 is a motor.

[0053] In actual applications, the interior of the mounting base 3 has a space for installing the first driving member 42 and the second driving member 52. After the first driving member 42 and the second driving member 52 are installed, the space is sealed by a cover plate.

When the second driving member 52 drives the working body 511 to rotate, when one abutment member 513 abuts against the handpiece 11 of the handle 1 fixed on the mounting seat 3, the working body 511 rotates to transmit the force through the abutment member 513, thereby driving the handpiece 11 to rotate relative to the connecting member 12; during the rotation of the handpiece 11 relative to the connecting member 12, the abutment member 513 remains against the handpiece 11; when the handpiece 11 rotates to the extreme position under the action of the abutment member 513, the working body 511 continues to rotate to separate the abutment member 513 from the handpiece 11, and the handpiece 11 will automatically rotate and reset; after the handpiece 11 is rotated and reset, another abutment member 513 abuts against the handpiece 11, and then the above steps are repeated.

[0057] Reference Figure 2 and Fig. 9 The rotating device 7 includes a rotating assembly 71 for driving the mounting seat 3 to rotate and a supporting seat 72 for supporting the rotating assembly 71 and the mounting seat 3.

The detection component 61 is installed on the mounting seat 3. The detection component 61 includes two detection elements 611. The two detection elements 611 detect the handpiece 11 when it is not rotated and pulled out and the handpiece 11 rotated and pulled out to the limit state respectively. When one of the detection elements 611 recognizes that the handpiece 11 is rotated to the limit state, the detection component 61 starts to prepare for detection; during the automatic rotation and reset of the handpiece 11, the detection component 61 detects the time required for the handpiece 11 to leave the detection range of the detection element 611 and enter the detection range of another detection element 611, and transmits the detection data to the control component 62, which determines whether the detection is qualified. Each handle 1 needs to be repeatedly detected multiple times. The handle 1 can be identified as a qualified product only when the multiple detection results are within the predetermined range. In this embodiment, the detection element 611 is preferably a photoelectric sensor. Since the photoelectric sensor is a common prior art, it will not be described in detail here.

[0064] The bottom of the control component 62 is fixedly connected to the machine body 2, and the control component 62 is located on one side of the mounting seat 3. The control component 62 can control the opening and closing of the first driving member 42, the second driving member 52, the third driving member 711 and the fourth driving member 712. At the same time, the control component 62 can control the rotation period of the working body 511 and the rotation amplitude of the fourth driving member 712.

[0065] The implementation principle of a buffer testing machine for automobile handles in the embodiment of the present application is as follows:

[0066] When the handle 1 is loaded, the control component 62 controls the third driving member 711 and the fourth driving member 712 to rotate until the mounting seat 3 is in a horizontal state. At this time, the loading frame 81 is closest to the mounting seat 3, and the two connecting members 12 of the handle 1 closest to the discharge port 811 in the loading frame 81 are respectively installed in the two mounting grooves 31 on the mounting seat 3. The control component 62 controls the first driving member 42 to drive the positioning member 41 to clamp and position the connecting portion 121 located in the mounting groove 31. At this time, the loading of the handle 1 is completed;

[0067] During the preliminary preparation of the buffer test of the handle 1, the control assembly 62 controls the third driving member 711 and the fourth driving member 712, and the third driving member 711 drives the fourth driving member 712 to rotate 90° toward the direction close to the second blanking frame 92, and the fourth driving member 712 also rotates a predetermined angle toward the direction close to the second blanking frame 92. At this time, the mounting seat 3 is in an inclined state, and the handle 1 fixed on the mounting seat 3 is the same as the actual state to be used;

[0068] During the buffer test of the handle 1, the control component 62 controls the second driving member 52 to start driving the working component 51 to rotate periodically. During the periodic rotation of the working component 51, the hand-held member 11 is driven to rotate relative to the connecting member 12, and the hand-held member 11 can automatically rotate and reset before being driven to rotate by the working component 51 next time; during the test, the hand-held member 11 needs to rotate and reset multiple times, and the detection component 61 detects the time required for the hand-held member 11 to automatically rotate and reset each time, and transmits the detection data to the control component 62, and the control component 62 compares each detection data with a given range, so as to make a judgment on the result of the current detection;

[0069] When the handle 1 fails to meet the test result once during the buffer test, the control component 62 will control the second driving member 52 to stop, and at the same time control the first driving member 42 to drive the positioning member 41 to loosen the connection portion 121 of the handle 1, and the handle 1 will fall to the first blanking frame 91 under the action of gravity for collection; when the handle 1 passes the test structure each time during the buffer test, the control component 62 will control the third driving member 711 and the fourth driving member 712 to rotate so that the mounting seat 3 rotates to a horizontal state, and when the mounting seat 3 rotates to its inclined lower end above the second blanking frame 92, the control component 62 will control the first driving member 42 to drive the positioning member 41 to loosen the connection portion 121 of the handle 1, and the handle 1 will slide from the mounting seat 3 along the sliding groove 33 under the action of gravity to the second blanking frame 92 for collection;

[0070] When performing the buffer test on the next handle 1, repeat the above steps.

[0071] Among them, according to the different specifications and sizes of handles of different models, the operator needs to rotate the control part to adjust the length of the working component, so that the working component can adapt to handles of different specifications and sizes; at the same time, according to the different position states of handles of different models after installation on the car roof, the operator needs to set the rotation angle of the fourth driving member through the control component, so that the position state of the handle to be buffered after the mounting seat is rotated is as close as possible to the actual application state.

[0072] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
