Description

Technical Field

[0001] The invention relates to the field of vehicle lamps, and in particular to a manual quick positioning clamping mechanism for a lamp base with high precision. Background Art

[0002] The light intensity, light distribution performance, photoelectric performance, etc. of the headlights are very important test items in the national mandatory standards. These test items are of great significance to driving safety. Therefore, the headlights need to be strictly tested before leaving the factory, that is, the automobile lamps are connected to the test equipment through the wiring harness, and then the test equipment completes the function test. The traditional way is to manually connect the body wiring harness to the lamps, and then connect the lamps to the test equipment for testing. The lamps need to be fixed before testing to ensure the accuracy of the test. This test method has certain defects:

[0003] 1. The lamp is an injection molded part, and the base is easily deformed. The previous positioning structure of profiles and support blocks is used to fix the lamp. The lamp is easy to shake in the fixture, which cannot meet the high positioning requirements of the parts, resulting in a decrease in detection accuracy and an increase in detection difficulty.

[0004] Second, the traditional positioning method requires continuous plugging and unplugging of the harness, which makes operation difficult and seriously affects the work efficiency. Moreover, when the harness is plugged and unplugged frequently, it will affect the contact accuracy and cause circuit instability, thus affecting the detection results.

[0005] 3. If the traditional clamping mechanism has a large clamping force, it will damage the headlights and cause waste. Summary of the invention

[0006] The object of the present invention is to provide a high-precision manual quick positioning clamping mechanism for a lamp base to solve the problems in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solutions:

A telescopic part is provided at one end of the guide column close to the pushing block, and when the telescopic part is extended, the clamping block can be driven to extend out of the guide column. A clamping block is provided at a position on the side wall of the guide column corresponding to the telescopic part, and the guide column can clamp the cylindrical hole on the lamp when the clamping block is extended.

[0014] Preferably, the clamping mechanism includes a clamping cylinder, a connecting block, a long slot, a wiring harness plug, a connecting column, a second slide rail, and a first stroke sensor. A clamping cylinder is provided on one side of the clamping column, and the clamping cylinder is used to drive the connecting column to move the connecting column in the direction of the clamping column. The clamping cylinder and the clamping column are connected by a connecting block, and the connecting block is fixedly arranged on the clamping column. A plurality of long slots are opened in the connecting block, and a wiring harness plug is arranged in the long slot. When the lamp is clamped in place, one end of the wiring harness plug located in the long slot contacts with the electronic components in the lamp, and one end of the wiring harness plug exposed in the long slot is connected with the circuit of the corresponding detection equipment to realize automatic plugging of the wiring harness. Then, the lamp can be tested for light intensity, light distribution performance, photoelectric performance, etc. A connecting column is provided on the side of the clamping cylinder away from the clamping column, and the output end of the clamping cylinder is fixedly connected to the connecting column and can be driven to move by the clamping cylinder.

The material of the lamp's assembly screws is steel, and the accuracy of its cylindrical hole is higher than that of the injection molded part and it does not deform. Therefore, the cylindrical hole on the lamp can be selected as the clamping position, avoiding the situation that the injection molded part is easy to deform and cannot be clamped in place.

A clamping handle is provided at a position of the clamping column away from the supporting column. After the lamp is clamped, it needs to be adjusted in the vertical direction. The handle is held by hand to drive the clamping column to slide up and down, so as to adjust the vertical position of the lamp. A No. 2 stroke sensor is provided at the position corresponding to the upper end of the supporting column and the clamping column.

A No. 3 travel sensor is provided on the upper end of the lower clamping column, and the No. 3 travel sensor is used to detect whether the lower part of the lamp has moved into place.

[0017] Preferably, an elbow clamp is provided at the middle of the support column and on the back side corresponding to the No. 3 stroke sensor. When the lamp is fixed in place both horizontally and vertically, the elbow clamp is used to make the final fixation of the lamp to further prevent the lamp from shaking during detection and affecting the detection results.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, since the screws of the lamp are made of steel, the precision of the cylindrical hole is higher than that of the injection molded part and it does not deform. Therefore, the method of clamping the lamp by the guide column and the cylindrical hole butting against each other can protect the lamp from damage and avoid the instability of clamping caused by deformation of the lamp.

[0020] 2. In the present invention, the lamp is clamped by a guide column and a cylindrical hole, and a rebound latch and a linear guide are used to quickly position the lamp. This high-precision fast positioning clamping mechanism is easy to operate and has high positioning accuracy, avoiding the use of traditional manual wiring harness plugging and unplugging methods, greatly reducing the detection accuracy and work intensity of this station. Due to the high positioning accuracy of the lamp, the detection accuracy of the CCD camera at this station is also greatly improved;

[0021] 3. In the present invention, the automatic plugging of the wire harness is realized while clamping, thus avoiding the traditional manual plugging and unplugging method, reducing the uncertainty of manual operation, and avoiding large errors in the detection results caused by loose wire harnesses;

[0022] 4. In the present invention, after the transport mechanism transports the lamp to the right place, the automatic clamping mechanism automatically clamps the lamp, and the automatic hole alignment mechanism can automatically locate the cylindrical hole on the lamp through micro-motion. After locating the hole, the clamping mechanism can initially fix the lamp, and there is no need to manually locate the clamping position, thus saving detection time.

[0043] The working principle of the present invention is as follows: first, the lamp is placed in the transport clamp 29 of the transport mechanism 25, and the front and rear slide rails 30 drive the transport clamp 29 to move forward and backward, driving the lamp to be located between the clamping mechanism 26 and the automatic clamping mechanism 28, so that the cylindrical hole on the lamp corresponds to the automatic clamping mechanism 28, and then the left and right slide rails 31 drive the transport clamp 29 to slightly move in the direction of the automatic clamping mechanism 28, driving the lamp and the automatic hole alignment mechanism 32 to cooperate with each other, so that the guide column 5 is inserted into the cylindrical hole on the lamp, and then the clamping mechanism 33 is operated to fix the cylindrical hole and the guide column 6 circumferentially, and the clamping mechanism 26 moves in the direction of the automatic clamping mechanism 28, so that the cylindrical hole on the lamp and the guide column 6 are axially fixed, and then the adjustment mechanism 27 drives the clamping column to adjust up and down, driving the lamp to move to a suitable position, and after the adjustment is completed, the lower end of the lamp enters 18 of the lower end clamping column 17, so that the lamp is clamped and the detection begins;

[0044] The operating principle of the automatic hole alignment mechanism 32 is as follows: when the guide column 6 and the cylindrical hole on the lamp cannot completely correspond, the left and right slide rails 31 drive the lamp and the automatic hole alignment mechanism 32 to interfere with each other, the front arm 34 or the rear arm 35 is pressed by an external force, the torsion spring 37 is deformed by the pressure, the lower end of the rear arm 35 slides in the slide groove 36, the angle between the front arm 34 and the rear arm 35 increases, and the front end of the guide column 6 is driven to slide into the cylindrical hole;

[0045] The operating principle of the clamping mechanism 33 is as follows: the motor 38 drives the rotating column 39 to rotate, drives the screw rod 40 to rotate, and a spiral motion occurs between the screw rod 40 and the ejection block 41, pushing the ejection block 41 in the direction of the telescopic member 42. The position of the center end of the telescopic member 42 is fixed by the fixing rod 44. The inclined surface of the ejection block 41 interferes with the telescopic member 42, driving the telescopic member 42 to stretch. The telescopic member 42 drives the clamping block 43 to move toward the outside of the guide column 6 until the clamping block 43 and the inner wall of the cylindrical hole are relatively fixed, so that the cylindrical hole and the guide column 6 are circumferentially fixed.
