The determination of the position of the door frame clamping groove 331 of the spring body 3 takes into account the inner contour space of the coating line on-site coating hanger and the corridor space of the coating line cab operation; and the internal volume and the paint discharge area of the cab, and calculating the complete entering and discharging of pretreatment cleaning solution, electrophoretic primer and the like in the cab in the takt time of the movement of the coating chain, wherein the minimum clearance between the door 4 and the door frame 5 is required to be opened and maintained; and then confirming the relative position relation between the door 4 and the doorframe 5 in the movement process by using the DMU movement checking function of the modeling software, thereby accurately determining the position of the doorframe clamping groove 331 on the spring body 3.
In order to ensure the clamping groove with a special shape and a flexible arc-shaped structure, the spring body 3 is designed to adopt the DMU motion checking function of modeling software, and is cut on a spring plate by a linear cutting means in manufacturing and processing, so that the process door lock after heat treatment can achieve the characteristics of good elasticity, good clamping position of the clamping groove, light operation and use and the like. Specifically, the guide shape of the spring body 3 confirms the movement locus of the door 4 using the DMU movement check function of the modeling software, and the shape and size of the guided sliding curved surface section 332 are designed according to the movement locus of the door 4. In order to facilitate the taking, the positioning, the clamping and the fixing of the door lock on the cab in the coating process and to fix the door 4 and the side wall doorframe 5 at a certain angle, the spring body 3 is made of an elastic material; in order to ensure the shape requirements of the door frame clamping groove 331 and the sliding curved surface section 332 with special shapes on the spring body 3, the spring body 3 is cut on the silicon-manganese spring steel plate by adopting a linear cutting means. The spring body 3 is preferably made of 60Si2Mn elastic material.
The door lock is integrally quenched with the hardness of 60HRC and the medium temperature tempering hardness of 42HRC, and the quenching is carried out according to the heat treatment requirement of the steel plate spring for the automobile so as to ensure the elasticity and rigidity of the door lock. The step positioning pin 1 is made of steel with certain hardness after heat treatment and is firmly welded with the spring body 3, so that the positioning accuracy of the step positioning pin and the supporting edge of the vehicle door 4 is ensured; after the spring body 3 is subjected to heat treatment, the door lock can achieve the characteristics of good elasticity, good bayonet clamping, light operation and use and the like by the coating process.

The door 4 is closed, the other end of the spring body 3 of the door lock in the coating process is provided with a guiding sliding curved surface section 332, the sliding curved surface section and the door frame 5 enter the door frame clamping groove 331 of the spring body 3 in a sliding mode, the door 4 is clamped and fixed, and the door frame 5 and the door 4 are enabled to keep a certain opening angle. The door 4 and the door frame 5 keep a gap of about 25 mm-35 mm, which is convenient for water filling, paint feeding, water draining, paint discharging and the like during the vehicle body coating pretreatment, electrophoresis and the like. When the door 4 needs to be opened by coating the coating glue and spraying the paint inside the cab, the opening handle 333 at the tail end of the spring body 3 is pulled to separate the door frame clamping groove 331 of the spring body 3 from the door frame 5, so that the door 4 can be opened.
In consideration of the convenience of field worker operation and the quality requirements of ensuring no covering point of paint spraying of a cab and the like, the door lock of the coating process is positioned and clamped in a clamping type fixing mode by using the characteristic shapes of parts of a cab door 4 and a door frame 5, no covering is carried out on finish paint, and the paint appearance of the cab is not influenced at all. When the automobile cab is opened, the rear part of the spring body 3 can be pulled, and parts of the cab cannot be touched. Particularly, when the door 4 is opened, the glue is coated, the paint is sprayed, and the door is closed after the paint is sprayed, the operation advantages are obvious, and the possibility that an operator touches an internal paint wet film is avoided.

The shape and the size of the process door lock of the cab door 4 are fully considered by the positioning mode and the size of the coating process door lock. The step positioning pin 1, the spring body positioning surface 313 of the spring body 3 and the lower part of the supporting clamping plate 2 are all corresponding to the edge of the lock hole 41 of the cab door 4, and any paint spraying surface cannot be shielded; when the step positioning pin 1 is positioned and clamped, the stress direction is parallel to the metal plate surface, and as shown by an arrow at the step positioning pin 1 in fig. 9, the metal plate is not subjected to distortion and deformation; similarly, the stress direction is also all in the parallel direction of panel beating face when spring body locating surface 313 rear portion and support cardboard 2 lower part chucking, as shown in the arrow that supports cardboard 2 department in fig. 9, all can not cause the panel beating to receive, distortion. The bending shape and size of the spring body 3, and the shape and size of the step positioning pin 1 and the support clamping plate 2 are tightly combined with the lock hole 41 of the vehicle door 4.
Compared with the existing technical door lock, the coating technical door lock fully combines the profile and the size characteristics of cab products, utilizes the elastic characteristic of materials and the self-limiting of component clamping grooves, and has the characteristics of simple structure, convenient manual operation, difficult damage and no need of excessive maintenance; almost no paint spraying covering exists, and all the working procedures of priming paint, finish paint and gluing are completed by one door lock; in addition, the door lock for the coating process can be used for driving cabs of various vehicle types.
The above-described embodiments of the present invention only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
