Description

Technical Field

[0001] This utility model relates to the field of lock pressing equipment technology, and in particular to a door lock pressing equipment with error prevention detection. Background Technology

[0002] In the automobile manufacturing process, door locks are a key component ensuring vehicle safety, and their pressing quality is crucial. Traditional door lock pressing equipment has many problems. On the one hand, there is a lack of effective error-proofing detection mechanisms before pressing. Workers find it difficult to accurately identify whether there are defects or incorrect installation orientations in the door lock components before operation, leading to the discovery of defective products only after pressing. This not only wastes a lot of manpower, material resources, and time, but also seriously affects production efficiency. For example, on some traditional assembly lines, due to the failure to detect minor defects in components in time, door locks may fail to lock or unlock properly after pressing, significantly reducing the safety performance of the entire vehicle and requiring a lot of rework. On the other hand, existing fixing devices have uneven clamping force when fixing door locks, which can easily cause the locks to shift during pressing. Some equipment uses a simple manual clamping method, and it is difficult for workers to uniformly apply force, resulting in the door locks not being firmly fixed and shifting during pressing, affecting pressing accuracy and thus reducing the quality and service life of the door locks. Therefore, it is necessary to design a door lock pressing equipment with error-proofing detection to solve the above problems. Utility Model Content

[0003] The main purpose of this utility model is to provide a door lock pressing device with error prevention detection, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A door lock pressing device with error prevention detection includes a worktable. A fixing device is fixedly connected to the upper right end of the worktable. A limit groove is opened at the front upper end of the worktable. A support plate is fixedly connected to the rear upper end of the worktable. A limit groove is opened at the upper end of the support plate. A pressing device is fixedly connected to the front end of the support plate. A control panel is fixedly connected to the right front end of the worktable. A placement groove is opened at the middle upper end of the worktable. A groove is opened at the upper front end of the worktable.

[0006] Preferably, the pressing device includes a second electric push rod and a first electric push rod. The output end of the second electric push rod passes through the support plate and is connected to a limit block at a certain height. The output end of the first electric push rod passes through the limit block and is fixedly connected to a fixing plate. A fixed outer shell is fixedly connected to the middle of the front end of the fixing plate. A visual inspection device is fixedly connected inside the fixed outer shell. A detection head is fixedly connected to the lower end of the visual inspection device. A pressing block is fixedly connected to the middle of the lower end of the fixing plate. The first electric push rod is fixedly connected to the middle of the upper end of the limit block. The second electric push rod is fixedly connected to the front end of the support plate.

[0007] Preferably, the fixing device includes a drive motor, the output end of which passes through the worktable and is fixedly connected to a positive and negative threaded rod. The left and right outer surfaces of the positive and negative threaded rods are threadedly connected to limit sliding plates. A left clamping block is fixedly connected to the upper end of the left limit sliding plate, and a right clamping block is fixedly connected to the upper end of the right limit sliding plate. Rubber pads are fixedly connected to the opposite surfaces of the left and right clamping blocks. The drive motor is fixedly connected to the upper right end of the worktable.

[0008] Preferably, the limiting block is slidably connected in the limiting groove, and the pressing block is located directly above the placement groove.

[0009] Preferably, the left end of the positive and negative threaded rod is movably connected to the left groove wall of the groove via a bearing, and the structure of the left clamping block is the same as that of the right clamping block and is symmetrically distributed from left to right.

[0010] Preferably, both of the limiting sliding plates are slidably connected within the limiting sliding groove.

[0011] Preferably, the visual inspection device performs error-proofing inspection on the door lock placed in the placement slot through the inspection head, and the inspection head is columnar with the lower end being the inspection end.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, the second electric push rod in the pressing device cooperates with the first electric push rod to achieve an orderly connection between visual inspection and pressing action. The second electric push rod pushes the limiting block to slide down in the limiting groove, which drives the visual inspection equipment to approach the door lock. Using the lower end of the columnar inspection head, it can accurately identify whether there are defects in the door lock parts, whether the installation direction is correct, etc. After the inspection is completed, the first electric push rod pushes the fixing plate down, so that the pressing block performs the pressing operation on the door lock, which greatly reduces the generation of defective products and significantly improves production efficiency.

[0014] 2. In this utility model, by using a drive motor to rotate the positive and negative threaded rods, since the left and right sides of the outer surface of the positive and negative threaded rods are threadedly connected to limit sliding plates, and the limit sliding plates slide in the limit sliding grooves, when the positive and negative threaded rods rotate, the two limit sliding plates can drive the left clamping block and the right clamping block to move synchronously in opposite directions or in opposite directions. The rubber pads on the opposite surfaces of the left and right clamping blocks not only increase the friction with the car door lock, but also prevent damage to the surface of the car door lock during the clamping process. This design ensures uniform clamping force on the car door lock, prevents displacement of the lock during the pressing process, effectively improves the pressing accuracy, and thus improves the quality of the car door lock.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A door lock pressing device with error prevention detection includes a workbench 1, a fixing device 4 fixedly connected to the upper right end of the workbench 1, a limit groove 6 opened at the front upper end of the workbench 1, a support plate 7 fixedly connected to the rear upper end of the workbench 1, a limit groove 9 opened at the upper end of the support plate 7, a pressing device 8 fixedly connected to the front end of the support plate 7, a control panel 3 fixedly connected to the right front end of the workbench 1, a placement groove 5 opened at the middle upper end of the workbench 1, and a groove 2 opened at the upper front end of the workbench 1.

[0025] In this embodiment, the pressing device 8 includes a second electric push rod 83 and a first electric push rod 81. The output end of the second electric push rod 83 passes through the support plate 7 and is connected to the limiting block 82 at a certain height. The output end of the first electric push rod 81 passes through the limiting block 82 and is fixedly connected to a fixing plate 84. A fixing housing frame 85 is fixedly connected to the middle of the front end of the fixing plate 84. A visual inspection device 86 is fixedly connected inside the fixing housing frame 85. A detection head 87 is fixedly connected to the lower end of the visual inspection device 86. A pressing block 88 is fixedly connected to the middle of the lower end of the fixing plate 84. The first electric push rod 81 is fixedly connected to the middle of the upper end of the limiting block 82. The second electric push rod 83 is fixedly connected to the front end of the support plate 7. The limiting block 82 is slidably connected in the limiting groove 9. The pressing block 88 is located directly above the placement groove 5. The visual inspection device 86 performs error-proofing detection on the door lock placed in the placement groove 5 through the detection head 87, and the detection head 87 is columnar with the lower end being the detection end.

[0026] Through the above scheme: when the pressing device 8 is working, the output end of the second electric push rod 83 pushes the limiting block 82 to slide down in the limiting groove 9, which drives the first electric push rod 81 and the fixing plate 84 to move down as a whole, so that the detection head 87 at the lower end of the vision inspection device 86 approaches the door lock placed in the placement groove 5 for error prevention detection. After the detection is completed, the output end of the first electric push rod 81 pushes the fixing plate 84 to move down further, so that the pressing block 88 performs the pressing operation on the door lock. Because the pressing block 88 is located directly above the placement groove 5 and the limiting block 82 slides in the limiting groove 9, the accuracy of the pressing position is ensured. This scheme, through the cooperation of the first electric push rod 81 and the second electric push rod 83, realizes the orderly performance of vision inspection and pressing actions. The lower detection end of the columnar detection head 87 can effectively perform error prevention detection on the door lock, avoid pressing errors, and improve the quality and efficiency of door lock pressing. At the same time, the fixed outer frame 85 protects the vision inspection device 86.

[0027] In this embodiment, the fixing device 4 includes a drive motor 41. The output end of the drive motor 41 passes through the workbench 1 and is fixedly connected to a positive and negative threaded rod 42. The left and right sides of the outer surface of the positive and negative threaded rod 42 are threadedly connected to a limiting sliding plate 43. The upper end of the left limiting sliding plate 43 is fixedly connected to a left clamping block 44, and the upper end of the right limiting sliding plate 43 is fixedly connected to a right clamping block 45. The opposite surfaces of the left clamping block 44 and the right clamping block 45 are fixedly connected to rubber pads 46. The drive motor 41 is fixedly connected to the upper right side of the workbench 1. The left end of the positive and negative threaded rod 42 is movably connected to the left groove wall of the groove 2 through a bearing. The structure of the left clamping block 44 is the same as that of the right clamping block 45 and is symmetrically distributed. Both limiting sliding plates 43 are slidably connected in the limiting groove 6.

[0028] Through the above scheme: When the fixing device 4 is working, the drive motor 41 drives the positive and negative threaded rod 42 to rotate. Since the left and right sides of the outer surface of the positive and negative threaded rod 42 are threadedly connected to the limiting sliding plate 43, and the two limiting sliding plates 43 are slidably connected in the limiting sliding groove 6, the rotation of the positive and negative threaded rod 42 causes the two limiting sliding plates 43 to drive the left clamping block 44 and the right clamping block 45 to move towards or away from each other. The rubber pads 46 on the opposite sides of the left clamping block 44 and the right clamping block 45 are used to clamp or release the door lock. This design The beneficial effect is that by utilizing the structural characteristics of the positive and negative threaded rod 42, the left clamping block 44 and the right clamping block 45 can move synchronously in opposite directions, ensuring uniform clamping force on the door lock. The rubber pad 46 increases the friction with the door lock and avoids damage to the surface of the door lock during clamping. The left end of the positive and negative threaded rod 42 is movably connected to the left groove wall of the groove 2 through a bearing, ensuring the stability of the threaded rod rotation. The overall structure is simple and compact, which can effectively improve the fixing reliability of the door lock during the pressing process.

[0029] It should be noted that this utility model is a door lock pressing device with error prevention detection. When this door lock pressing device with error prevention detection is working, the door lock is first placed in the placement slot 5 of the workbench 1. The drive motor 41 is started via the control panel 3. The drive motor 41 drives the positive and negative threaded rod 42 to rotate. Since the left and right sides of the outer surface of the positive and negative threaded rod 42 are threadedly connected to limit sliding plates 43, and both limit sliding plates 43 are slidably connected in the limit sliding groove 6, the rotation of the positive and negative threaded rod 42 causes the two limit sliding plates 43 to move the left clamping block 44 and the right clamping block 45 towards each other. The rubber pads 46 on the opposite sides of the left clamping block 44 and the right clamping block 45 clamp and fix the door lock. Then, the machine is started... The second electric push rod 83 pushes the limiting block 82 to slide down within the limiting groove 9. Then, the first electric push rod 81 is activated, and its output pushes the fixing plate 84 down, causing the detection head 87 at the lower end of the vision inspection device 86 to perform error-proof detection on the door lock placed in the placement groove 5. After the detection is completed, the first electric push rod 81 continues to push the fixing plate 84 down, causing the pressing block 88 at the lower center of the fixing plate 84 to perform a pressing operation on the door lock. Since the pressing block 88 is located directly above the placement groove 5, the pressing operation is ensured to be accurate. The entire process realizes the door lock from fixing, detection to pressing operation, effectively improving work efficiency and accuracy.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
