Description

Technical Field

[0001] This invention relates to the field of automotive parts oiling technology, specifically to an automotive door lock parts oiling device. Background Technology

[0002] Car door locks typically consist of a lock housing and a bolt. The bolt extends and retracts within the lock housing. There are various types of door locks, most of which have complex structures and require numerous assembly steps. Due to the frequent movement of the bolt, the internal parts of the door lock will wear down due to frequent opening and closing actions. Therefore, it is necessary to apply lubricating oil to the door lock before assembly to make the opening and closing smoother, thereby reducing wear during normal use and extending the service life of the door lock.

[0003] Chinese invention patent CN119368365A discloses an oiling device for automotive door lock components, including an oiling frame and a door lock component body. One side of the oiling frame is recessed to form a container cavity for placing the door lock component body. An oiling assembly is located above the container cavity, used to maintain a distance between the door lock component body and the lock body within the container cavity. The oiling assembly includes a support frame fixed within the container cavity, a support crossbar mounted on one side of the support frame, and two symmetrically sliding guide rails on the side of the support crossbar away from the support frame, used to limit the door lock component body. This invention, through the oiling assembly, enables the door lock component body to be hollow within the container cavity, allowing for sufficient lubrication of the entire surface of the door lock component body. This increases the speed of oiling the door lock component body, improving the production efficiency and quality of the device.

[0004] However, the above-mentioned patent still has the following shortcomings in actual use: the patent clamps the main body of the door lock accessory by using a coating stabilizer, so that the main body of the door lock accessory is suspended in the container cavity. However, the part of the coating stabilizer that contacts the main body of the door lock accessory still cannot be coated, resulting in missed coating. Moreover, the main body of the door lock accessory needs to be loaded and unloaded from the coating stabilizer one by one by workers, which affects the coating efficiency of the main body of the door lock accessory.

[0019] Secondly, the third electric push rod of the present invention drives the abutment block to move forward, and the telescopic plate can also move forward. The telescopic plate acts as a carrier to support the main body of the door lock accessory. When the telescopic plate moves backward, the telescopic plate cannot move backward synchronously because the locking rod is inserted into the insertion slot. The angle adjustment motor drives the telescopic plate to rotate, which allows the main body of the door lock accessory to be unloaded, thereby realizing automatic unloading operation.

[0034] An oiling device for automotive door lock parts includes a door lock part body 1, a vibratory feeder (not shown) for conveying the door lock part body 1, and a processing frame 2. The bottom of the processing frame 2 is provided with a holding bracket 21, the top of the holding bracket 21 is provided with a collection box 22, the middle of the processing frame 2 is provided with a support plate 23, the top of the support plate 23 is provided with a guiding mechanism 3 for sequentially guiding multiple door lock part bodies 1, a first oiling mechanism 4 for oiling the four sides of the door lock part body 1, and a feeding mechanism 5 for assisting the unloading of the oiled door lock part body 1 into the collection box 22. The inner top wall of the processing frame 2 is provided with a suspension 24, the suspension 24 is provided with a second oiling mechanism 6 for oiling the head and tail ends of the door lock part body 1, and a positioning mechanism 7 for positioning the door lock part body 1. The vibratory feeder is located on the side of the processing frame 2, and the discharge end of the vibratory feeder is connected to the head end of the guiding mechanism 3.

[0035] This invention enables the sequential arrangement and conveying of the main body 1 of the door lock component through a vibratory feeder. The guide mechanism 3 transfers and guides the main body 1 of the door lock component conveyed by the vibratory feeder. The positioning mechanism 7 and the first oiling mechanism 4 work together to uniformly spray oil onto the top, bottom, left, and right sides of the main body 1 of the door lock component. The positioning mechanism 7, the unloading mechanism 5, and the second oiling mechanism 6 work together to uniformly spray oil onto the head and tail of the main body 1 of the door lock component. The unloading mechanism 5 automatically unloads the oiled main body 1 of the door lock component into the collection box 22, thereby realizing the automatic oiling operation of the main body 1 of the door lock component, improving the efficiency and quality of the spraying.

[0036] When using this device, the main body 1 of the door lock accessory is first fed into the vibratory feeder. Then, the vibratory feeder can vibrate and convey the main body 1 of the door lock accessory in sequence. After that, the main body 1 of the door lock accessory can enter the guiding mechanism 3 from the discharge end of the vibratory feeder in sequence.

[0037] The material guiding mechanism 3 includes a first support column 31, a U-shaped material guiding frame 32, and a top cover 33. Two symmetrically arranged mounting seats 34 are provided on both sides of the U-shaped material guiding frame 32. Each mounting seat 34 has mounting holes. The bottom of the top cover 33 has an embedded block 35 and four screws 36. Nuts 361 are screwed onto each screw 36. A mounting bracket 37 is provided at the top of the tail end of the top cover 33. A first electric push rod 371 is provided at the top of the mounting bracket 37. An L-shaped baffle 372 is provided at the output end of the first electric push rod 371. The top of the tail end of the cover 33 is provided with a first sliding groove 331 that cooperates with the L-shaped baffle 372. The first support column 31 is set on the top of the support plate 23. The U-shaped guide frame 32 is inclinedly set on the top of the first support column 31. The inner block 35 is slidably set in the U-shaped guide frame 32. A guide channel 38 is formed between the U-shaped guide frame 32 and the inner block 35 for the door lock accessory body 1 to slide down. The screw 36 is located in the mounting hole. The head end of the guide channel 38 is connected to the discharge end of the vibratory feeder.

[0038] The material guiding mechanism 3 also includes a guide hopper 39. The top of the guide hopper 39 is provided with a connecting block 391. The connecting block 391 is fixedly connected to the outer wall of the processing frame 2. The material guiding channel 38 and the vibratory feeder are connected through the guide hopper 39.

[0039] The main body 1 of the door lock accessory first enters the guide hopper 39, which guides the main body 1 in the center so that it can smoothly enter the guide channel 38. Since the U-shaped guide frame 32 is inclined, the main body 1 of the door lock accessory can slide down by its own gravity after entering the guide channel 38. The main bodies 1 of the door lock accessory that enter the guide channel 38 can be arranged in sequence. After the main body 1 of the door lock accessory at the front extends out of the guide channel 38, the first electric push rod 371 drives the L-shaped baffle 372 to move down. The L-shaped baffle 372 blocks the other main bodies 1 of the door lock accessory in the guide channel 38.

[0040] By sequentially adjusting the rotating nut 361, the position of the entire top cover 33 can be changed. The top cover 33 can drive the inner insert 35 to move synchronously, thereby changing the cross-sectional area of ​​the material guide channel 38. Thus, the size of the material guide channel 38 can be adjusted. The top cover 33 is also easy to install and remove, which facilitates maintenance.

[0041] The positioning mechanism 7 and the second oiling mechanism 6 work together to spray oil onto the front end of the door lock accessory body 1 located at the foremost point.

[0043] The sixth electric push rod 71 can drive the bidirectional electric push rod 72 to move downward. The two clamping claws 74 on the bidirectional electric push rod 72 can contact the head end of the door lock accessory body 1 located at the foremost point. Then, the bidirectional electric push rod 72 drives the two clamping claws 74 to move in the opposite direction. After that, the door lock accessory body 1 can enter between the two clamping claws 74. The bidirectional electric push rod 72 drives the two clamping claws 74 to clamp and fix the middle part of the door lock accessory body 1. Then, the fifth electric push rod 61 drives the horizontal frame 62 to move downward. After the second oiling head 66 is aligned with the door lock accessory body 1, the translation screw slide 63 drives the second motor 64 to translate left and right. The second motor 64 drives the mounting platform 65 to translate left and right. The mounting platform 65 drives the second oiling head 66 to move synchronously. The head end of the door lock accessory body 1 located at the foremost point can be evenly sprayed with oil.

[0044] After the oil spraying operation is completed on the head end of the door lock accessory body 1, the fifth electric push rod 61 drives the transverse frame 62 to return to the initial position. Then the unloading mechanism 5 works. The unloading mechanism 5 includes a second electric push rod 51, a bending plate 52, an angle adjustment motor 53, a return frame 54, a telescopic plate 55, an abutment block 56, a locking component 57 for locking the telescopic plate 55, and an auxiliary component 58 for guiding the oiled door lock accessory body 1 into the collection box 22. A connecting plate 531 is provided on the output end of the angle adjustment motor 53. A third electric push rod 541 is provided on the top of the return frame 54. An internal groove 551 is opened at the tail end of the telescopic plate 55. Multiple first springs 552 are connected in the internal groove 551. A cover 542 is provided at the tail end of the return frame 54. A blocking block is provided at the bottom of the head end of the telescopic plate 55. 553, the abutment block 56 has a second sliding groove 561 that slides with the telescopic plate 55. The bottom of the groove at the head end of the second sliding groove 561 has a moving groove 562 for the blocking block 553 to move. The second electric push rod 51 is vertically set at the bottom of the support plate 23. The bottom of the bending plate 52 is fixedly connected to the output end of the second electric push rod 51. The angle adjustment motor 53 is connected to one side wall of the bending plate 52. The return frame 54 is set at an angle. The cover 542 is fixedly connected to the connecting plate 531. The telescopic plate 55 is slidably set in the return frame 54. One end of the first spring 552 is fixedly connected to the cover 542. The output end of the third electric push rod 541 is fixedly connected to the back of the abutment block 56. The locking component 57 is set on the outer wall of the return frame 54. The auxiliary component 58 is set on the top of the support plate 23.

[0045] The locking assembly 57 includes an L-shaped synchronizing rod 571, a second spring 572, and a telescopic seat 573. One end of the L-shaped synchronizing rod 571 is provided with a first wedge surface 5711. A locking rod 5731 is slidably provided inside the telescopic seat 573. A force-bearing block 574 is provided at the tail end of the locking rod 5731. A second wedge surface 5741 that cooperates with the first wedge surface 5711 is provided at one end of the force-bearing block 574.

The guide pipe 582 is inclined on the second support column 581, and the discharge end of the guide pipe 582 is located directly above the collection box 22.

[0047] The second electric push rod 51 drives the bending plate 52 to move upward. The bending plate 52 drives the angle adjustment motor 53 and the return frame 54 to move upward. After the abutment block 56 is aligned with the door lock accessory body 1 at the front end, the third electric push rod 541 drives the abutment block 56 to move forward. Since a step is formed between the second slide groove 561 and the moving groove 562, this step can drive the blocking block 553 to move forward synchronously when the abutment block 56 moves forward. The blocking block 553 can drive the telescopic plate 55 to move forward synchronously. The telescopic plate 55 gradually extends out of the return frame 54, and all the first springs 552 in the built-in groove 551 become stretched. The tail end of the telescopic plate 55 The insertion slot 554 gradually approaches the locking rod 5731. After the locking rod 5731 aligns with the insertion slot 554, the elastic force of the second spring 572 pulls the force block 574 towards the side wall of the U-shaped frame 54. The force block 574 drives the locking rod 5731 to move synchronously. After the locking rod 5731 is inserted into the insertion slot 554, the abutment block 56 also abuts against the head end of the door lock accessory body 1 located at the foremost end. At the same time, the bidirectional electric push rod 72 drives the two clamping claws 74 away from the door lock accessory body 1. Most of the door lock accessory body 1 is still located in the guide channel 38. Then the first oiling mechanism 4 starts to work.

[0048] The first oiling mechanism 4 includes a third support column 41, a U-shaped bracket 42, and a top block 43. The top of the U-shaped bracket 42 has two symmetrically arranged annular discs 44, with a rotating ring 45 rotatably positioned between the two discs 44. A first oiling head 451 is mounted on the rotating ring 45, and a driven gear 452 is mounted on the outer wall of the rotating ring 45. A first motor 421 is mounted on the side wall of the U-shaped bracket 42, and a driving gear 422 is mounted on the output end of the first motor 421. The driving gear 422 meshes with the driven gear 452. The bottom of the frame 42 is provided with a T-shaped slider 423, and the top block 43 is provided with a third sliding groove 431 that slides with the T-shaped slider 423. The third sliding groove 431 is provided with a fourth electric push rod 432. The output end of the fourth electric push rod 432 is fixedly connected to the T-shaped slider 423. The third support column 41 is provided on the top of the support plate 23. The top block 43 is inclined on the top of the third support column 41 and is parallel to the U-shaped guide frame 32. The discharge end of the guide channel 38 is located on the side of the rotating ring 45.

[0049] The fourth electric push rod 432 drives the T-shaped slider 423 to move forward in the third slide groove 431. The T-shaped slider 423 drives the U-shaped bracket 42, the ring disk 44, and the rotating ring 45 to move synchronously. The rotating ring 45 drives the first oiling head 451 to move synchronously, thereby adjusting the position of the first oiling head 451 so that it is aligned with the head end of the door lock accessory body 1. Then, the first motor 421 drives the drive gear 422 to rotate, the drive gear 422 drives the driven gear 452 to rotate, and the driven gear 452 drives the rotating ring 45 to rotate synchronously. After the rotating ring 45 rotates 360 degrees, the first motor 421 stops working, and the first oiling head 451 can... After a uniform spraying of oil is performed around the head of the door lock component body 1, the fourth electric push rod 432 drives the T-shaped slider 423 to move backward a certain distance, so that the first oiling head 451 is aligned with the next section of the door lock component body 1. Then, the first motor 421 drives the drive gear 422 to rotate in the opposite direction, and the rotating ring 45 drives the first oiling head 451 to rotate 360 ​​degrees in the opposite direction. The first oiling head 451 performs a uniform spraying of oil around the next section of the door lock component body 1. This cycle continues until the first oiling head 451 has completed a uniform spraying of oil on the part of the door lock component body 1 located at the discharge end of the guide channel 38. Then, the third electric push rod 541 drives... The abutment block 56 moves backward a certain distance. Since the telescopic plate 55 is locked by the locking rod 5731, the telescopic plate 55 does not move backward synchronously with the abutment block 56. The main body 1 of the door lock accessory extends out of the guide channel 38. The telescopic plate 55 provides support for the main body 1 of the door lock accessory. The first motor 421 drives the rotating ring 45 to rotate 360 ​​degrees. The first oiling head 451 performs a uniform oil spraying operation on the part extending out of the guide channel 38. Then, the third electric push rod 541 drives the abutment block 56 to move backward a certain distance. This cycle continues until the main body 1 of the door lock accessory is completely moved to the top of the telescopic plate 55. The main body 1 of the door lock accessory is also uniformly oiled around its perimeter. After the operation, the third electric push rod 541 continues to drive the abutment block 56 to move backward, and the main body 1 of the door lock accessory moves backward on the top of the telescopic plate 55, so that the main body 1 of the door lock accessory is away from the guide channel 38. Then the fifth electric push rod 61 drives the transverse frame 62 to move down. At the same time, the second motor 64 drives the mounting table 65 to rotate 180 degrees, and the second oiling head 66 also rotates 180 degrees with the mounting table 65. The oil outlet end of the second oiling head 66 faces the tail end of the main body 1 of the door lock accessory. Then the translation screw slide 63 drives the mounting table 65 to move left and right. The mounting table 65 drives the second oiling head 66 to move synchronously, and the tail end of the main body 1 of the door lock accessory can also be evenly sprayed with oil.

[0050] After the spraying is completed, the fifth electric push rod 61 drives the transverse frame 62 to return to the initial position, the angle adjustment motor 53 drives the connecting plate 531 to rotate, the connecting plate 531 drives the return frame 54 and the telescopic plate 55 to rotate synchronously, and the door lock accessory body 1 then slides down and falls onto the protruding receiving part 583 by its own gravity. After that, the door lock accessory body 1 enters the guide pipe 582, and the guide pipe 582 guides the door lock accessory body 1 into the collection box 22 for collection.

[0051] Furthermore, an external plate 221 is provided on the outer wall of the collection box 22, and an inclined rubber buffer plate 222 is connected to the external plate 221. The rubber buffer plate 222 is located directly below the discharge end of the guide pipe 582.

[0052] The rubber buffer plate 222 can cushion the door lock accessory body 1 that enters the collection box 22, preventing damage caused by excessive downward movement.

[0053] After the door lock accessory body 1 at the foremost end completes the oil spraying operation, the third electric push rod 541 drives the abutment block 56 to continue moving backward. The first wedge surface 5711 on the L-shaped synchronous rod 571 gradually abuts against the second wedge surface 5741 on the force block 574. Through the cooperation of the first wedge surface 5711 and the second wedge surface 5741, the force block 574 moves outward. The force block 574 drives the locking rod 5731 to move outward. The locking rod 5731 disengages from the insertion slot 554, and the telescopic plate 55 loses its lock. The elastic force of all the first springs 552 drives the telescopic plate 55 to retract into the return frame 54. Of course, a rubber buffer layer can be provided on the return frame 54 and the blocking block 553 to provide buffer. Then, the first electric push rod 371 drives the L-shaped baffle 372 to move up and down, so that the next one can gradually extend out of the guide channel 38. By using the above method, the door lock accessory body 1 can realize automatic feeding, automatic oil spraying and automatic unloading operations.

[0054] Of course, the support plate 23 also has multiple through holes for oil leakage. The bottom of the support plate 23 is equipped with an oil tank for collecting oil. Both the oil tank and the oil drum for storing oil are equipped with oil pumps. The oil pumps are connected to the first oiling head 451 or the second oiling head 66 through pipes.
