Description

Technical Field

[0001] The invention relates to the field of automobile bolt preparation equipment, and in particular to cold heading equipment for automobile bolt processing. Background Art

[0002] A bolt is a type of fastener consisting of a head and a screw (a cylinder with external threads). It needs to be used in conjunction with a nut to fasten two parts with through holes. This type of connection is called a bolt connection.

[0003] Generally, the external threads on the screw are processed after the bolt body is prepared, so the processing quality of the bolt body directly affects the cost and product quality.

[0004] Due to the problem of oil mist, the existing bolt cold heading processing equipment all adopts a closed structure and cooperates with a robot to load and unload materials to achieve safe and reliable production. The processing shape in some cold heading processes is poorly grasped, and manual observation can only be made from one side, which is not conducive to the recording of the production process and repair and maintenance work.

[0005] For example, patent number CN: 208628369 U discloses a cold heading equipment for automobile bolt processing, which uses a monitoring camera to monitor the cold heading die inside the equipment. Through the image, the technicians can know the processing situation in more detail, and the image clarity of the monitoring camera is guaranteed by wiping the components. However, since the monitoring camera lens is attached with oil stains, the image clarity of the monitoring camera cannot be guaranteed by wiping only without spraying cleaning fluid. On the contrary, the more the lens is wiped, the more turbid the lens surface becomes and the lower the image clarity becomes. Summary of the invention

[0006] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art.

[0007] Provided is a cold heading device for automobile bolt processing, which can observe the processing process from multiple perspectives, assist in reducing the difficulty of repair and maintenance, and has low maintenance difficulty of the observation equipment.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cold heading equipment for automobile bolt processing, comprising a main body, a cold heading die and a manipulator are arranged in the main body, the manipulator cooperates with the cold heading die to transfer the processed workpiece, a monitoring camera is also arranged in the main body, a protective cover shell is arranged outside the monitoring camera, the protective cover shell is formed by sealing and splicing a front end plate, a rear end plate, a left side plate, a right side plate, a top plate and a bottom plate, a lens hole is opened on the front end plate, a lens is connected in the lens hole, a bracket is arranged at the front end of the lens, a rotating cylinder is arranged on the top plate, a cylinder is connected to the rotating cylinder, a pull rod is connected to the cylinder rod of the cylinder, a protective cover is arranged at the end of the pull rod away from the cylinder rod, and the pull rod is connected to the protective cover through a linkage assembly.

[0009] By adopting the above technical scheme, the cold heading die includes a shaping station, a head preforming station, a rod bundling station and a forming station which are arranged in sequence. The cold heading die is monitored by a monitoring camera. Through the image information, the technicians can perceive the processing conditions in more detail, thereby making more accurate judgments and improving the efficiency of maintenance and repair. When the equipment is running, the cylinder rod of the cylinder extends the linkage pull rod, and the pull rod lowers the protective cover through the linkage assembly. The protective cover is abutted against the bracket, thereby preventing the lens from oil mist. When there is too much oil mist on the protective cover, making it difficult to observe the image, the cylinder is retracted, the pull rod returns to its position, and at the same time, the rotating cylinder drives the cylinder and the protective cover to rotate 180°, and the protective cover is turned to the observation window or protective plate close to the main body. After the protective plate or observation window is replaced, the rotating cylinder returns to its position, and the cylinder brings out the protective cover through the pull rod and the linkage assembly to re-abut on the lens. Not only is the replacement convenient and quick, but it also improves the graphic forming accuracy of the monitoring camera and improves the stability of the technician's judgment.

[0010] The above-mentioned cold heading equipment for automobile bolt processing can be further configured as follows: the linkage assembly includes a 7-shaped linkage block connected to the pull rod, the rotary cylinder is provided with a relatively established support bracket above the bracket, one end of the linkage block is rotatably connected to the support bracket, and the other end is fixedly connected to the pull rod, the protective cover includes a protective glass and a plastic protective cover mounted outside the protective glass, and the other end of the linkage block relatively connected to the pull rod is detachably connected to the protective cover.

[0011] By adopting the above technical solution, one end of the linkage block is movably connected to the pull rod, and the other end is movably connected to the support bracket. When the cylinder pushes the pull rod to move, the linkage block moves circumferentially along the connection with the support bracket under the action of the pull rod. Due to the presence of the support bracket, when the linkage block moves to abut against the support bracket, the protective cover abuts against the bracket. Since the protective cover of the protective cover is detachably connected to the linkage block, it is more convenient to replace the protective cover.

[0012] The above-mentioned cold heading equipment for automobile bolt processing can be further configured as follows: the other end of the linkage block relative to the connecting rod is a U-shaped protective cover connecting end, the protective cover connecting end is provided with relatively set connecting protrusions, and the two ends of the protective cover are provided with connecting grooves adapted to the connecting protrusions, and the protective cover is connected to the connecting protrusion through the connecting grooves.

[0013] By adopting the above technical solution, through the design of the connecting protrusion and the connecting groove, when the protective cover needs to be replaced, the protective cover connecting end of the plastic linkage block is pulled outward to disengage the connecting protrusion from the connecting groove, thereby replacing the protective cover.

[0014] The above-mentioned cold heading equipment for automobile bolt processing can be further configured as follows: a connecting through hole is provided on the supporting bracket, and a second connecting through hole adapted to the connecting through hole is provided at the connecting through hole of the linkage block, and the linkage block and the supporting bracket are connected by rotating shafts respectively penetrated through the connecting through hole and the second connecting through hole.

[0015] By adopting the above technical solution, the connection and assembly are more convenient. After assembly, retaining springs are respectively arranged between the two ends of the rotating shaft and the supporting bracket to prevent the rotating shaft from falling out.

[0016] The above-mentioned cold heading equipment for automobile bolt processing may be further configured as follows: a light source is also provided on the bracket.

[0017] The above-mentioned cold heading equipment for automobile bolt processing may be further configured as follows: the light source is an LED lamp.

[0018] The above technical solution is adopted to set a light source. Since the internal environment of the device is relatively dark, the clarity of the shooting is improved by setting a light source.

[0019] The beneficial effects of the present invention are as follows: the protective cover is easy to replace, so that the shooting picture of the monitoring camera is clearer, and the judgment accuracy of the technicians is improved.
