Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of threaded buffer blocks, and in particular to a threaded buffer block knob device. Background Technology
[0002] Cars inevitably experience various opening and closing collisions due to various reasons, such as the opening and closing of car doors. Using car bumper blocks to cushion these collisions is an effective way to improve the user experience. Currently, the production process of threaded bumper blocks requires screwing plastic bolts into plastic sleeves, after which buffer rubber heads are added. Currently, this is mostly done manually, requiring the screws to be screwed into relatively long threads, resulting in high labor intensity and inconsistent thread depths. Summary of the Invention
[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a threaded buffer block knob device.
[0004] This utility model provides a threaded buffer block knob device, including a frame 1, on which a bracket 2 and a positioning component 8 are provided. The top of the positioning component 8 is provided with a positioning groove 8.1. A lifting plate 5 driven by a lifting cylinder 3 is slidably mounted on the bracket 2. A servo motor 6 is provided facing downwards on the lifting plate 5. A knob head 7 located above the positioning groove 8.1 and used for turning the plastic bolt is connected to the output shaft of the servo motor 6. A clamping cylinder 9 for clamping the plastic sleeve is provided on the side wall of the positioning component 8.
[0005] Furthermore, the bracket 2 is provided with slide rails 4 vertically and symmetrically arranged, and a slider is slidably mounted on the slide rails 4, and the lifting plate 5 is installed on the slider.
[0006] Furthermore, a hexagonal groove is provided at the center of the bottom of the knob head 7.
[0007] Furthermore, the upper end of the positioning member 8 is symmetrically provided with notches on the left and right sides, which communicate with the positioning groove 8.1 and allow the gripper of the gripper cylinder 9 to pass through.
[0008] Furthermore, it also includes a limiting component 10, which includes a sensing ring 10.1 disposed on the knob head 7, and a displacement sensor 10.2 that contacts and senses the sensing ring 10.1 is vertically disposed on the side wall of the positioning member 8.
[0009] Furthermore, it also includes a buffer assembly 11, which includes a fixed block 11.1 installed on the side wall of the lifting plate 5, and the bracket 2 is provided with a hydraulic buffer 11.2 for buffering the fixed block 11.1 and a limiting bolt 11.3 for limiting the fixed block 11.
[0010] Furthermore, a photoelectric sensor 12 is provided on the upper part of the frame 1.
[0011] The advantages of this invention are as follows: a gripper cylinder clamps the plastic sleeve, a lifting cylinder drives a servo motor to lower the knob head, thereby allowing the knob head to turn the plastic bolt, reducing manual labor intensity and improving efficiency; the plastic sleeve is placed into the positioning groove, thus positioning the plastic sleeve; the lifting cylinder drives the lifting plate and its components to descend, and the knob head, which descends with the lifting plate, contacts the plastic bolt, and the servo motor drives the knob head to rotate to turn the plastic bolt, thus turning the plastic bolt into the plastic sleeve; the hexagonal groove corresponds to the hexagonal head of the plastic bolt, and the knob head turns the plastic bolt through the hexagonal groove; the sensing ring, which descends with the knob head, contacts the displacement sensor, and the displacement sensor transmits a signal to the control system, which stops the lifting cylinder from descending, thus limiting the descent position of the knob head; the hydraulic buffer buffers the vertically moving fixed block, and the limit bolt provides protective limitation for the vertically moving fixed block.

Detailed Implementation
[0013] The present invention will now be described in detail with reference to the accompanying drawings.
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0015] See Figures 1 to 6This utility model provides a threaded buffer block knob device, which includes a frame 1, a bracket 2 and a positioning component 8 on the frame 1. The top of the positioning component 8 is provided with a positioning groove 8.1, and a plastic sleeve is placed into the positioning groove to position the plastic sleeve. A lifting plate 5 driven by a lifting cylinder 3 is slidably mounted on the bracket 2. A slide rail 4 is vertically and symmetrically arranged on the bracket 2. A slider is slidably mounted on the slide rail 4. The lifting plate 5 is installed on the slider. A servo motor 6 is arranged downward on the lifting plate 5. A knob head 7 located above the positioning groove 8.1 and used to turn the plastic bolt is connected to the output shaft of the servo motor 6. The knob head is made of polyurethane and has a certain buffer. A gripper cylinder 9 for clamping the plastic sleeve is provided on the side wall of the positioning component 8. The worker inserts the plastic bolt into the plastic sleeve and pre-tightens the thread slightly. Then, the plastic sleeve is positioned in the positioning groove. The gripper of the clamping cylinder clamps the plastic sleeve. Next, the lifting cylinder drives the lifting plate and its components to descend. As the lifting plate descends, the knob head contacts the plastic bolt. The servo motor drives the knob head to rotate and turn the plastic bolt (the knob head rotates while descending), thus automatically turning the plastic bolt into the plastic sleeve. The descent stroke of the lifting cylinder is controllable, and the plastic sleeve remains stationary, thereby ensuring a uniform thread depth of the knob. Then, the servo motor stops, and the lifting cylinder drives the lifting plate and its components to rise and reset. After the gripper cylinder releases the plastic sleeve, the worker removes the assembled plastic sleeve.
[0016] See Figure 4 The center of the bottom of the knob head 7 has a hexagonal groove. The hexagonal groove corresponds to the hexagonal head of the plastic bolt. The knob head rotates the plastic bolt through the hexagonal groove. The knob head is made of polyurethane and has a certain buffer. When the knob head descends, if the hexagonal groove does not engage with the hexagonal head of the plastic bolt, the knob head will provide a buffer until the rotating hexagonal groove engages with the hexagonal head of the plastic bolt.
[0017] The upper end of the positioning component 8 has symmetrical notches on the left and right sides that communicate with the positioning groove 8.1 and allow the gripper of the gripper cylinder 9 to pass through.
[0018] It also includes a limiting component 10, which includes a sensing ring 10.1 disposed on the knob head 7, and a displacement sensor 10.2 disposed vertically on the side wall of the positioning member 8, which contacts and senses the sensing ring 10.1. When the knob head descends to the correct position, the sensing ring descending with the knob head contacts the displacement sensor, and the displacement sensor transmits a signal to the control system. The control system then stops the lifting cylinder from descending, thereby limiting the descent position of the knob head.
[0019] It also includes a buffer assembly 11, which includes a fixed block 11.1 installed on the side wall of the lifting plate 5. The bracket 2 is provided with a hydraulic buffer 11.2 for buffering the fixed block 11.1 and a limiting bolt 11.3 for limiting the fixed block 11. The hydraulic buffer and the limiting bolt are diagonally distributed from left to right. The fixed block is located between the hydraulic buffer and the limiting bolt. The hydraulic buffer buffers the fixed block that moves up and down, and the limiting bolt provides protective limitation for the fixed block that moves up and down.
[0020] A photoelectric sensor 12 is installed on the top of the frame 1. The photoelectric sensor can sense the buffer block placed in the positioning slot, and transmit the signal to the control system. The control system controls the operation of the lifting cylinder, servo motor, and gripper cylinder.
[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
