Description

Technical Field

[0001] The present invention relates to the processing field of automotive door lock assemblies, and particularly to a drilling processing device for automotive door lock assemblies. Background Art

[0002] An automotive door lock assembly is a device used to lock and unlock automotive doors, mainly composed of a door lock actuator, an electronic control unit, a door lock mechanism, etc. The door lock mechanism includes components such as a door lock pin, a lock tongue fixing member, a lock catch, etc. The lock tongue fixing member usually refers to a component used to fix and control the lock tongue, which is an indispensable part of the door lock mechanism and has high durability and reliability. The common lock tongue fixing member is octagonal in shape, with a middle round hole for installing and fixing the lock tongue. There are also two screw mounting holes (as shown in Figure 9 ) on both sides of the middle round hole of the lock tongue fixing member. The screw mounting holes can cooperate with screws to fix the lock tongue fixing member, and the screw mounting holes are usually formed by drilling.

[0003] However, the following problems still exist in the current drilling process of the screw mounting holes of the lock tongue fixing member:

[0004] (1) Since the lock tongue fixing member is small and thin, it is difficult to firmly position and clamp it. The lock tongue fixing member is prone to offset during drilling, which affects the quality and accuracy of drilling. At the same time, it is difficult for the lock tongue fixing member to maintain an accurate position and direction during the drilling process, resulting in poor consistency of the drilling position and size.

[0005] (2) Usually, the lock tongue fixing members are loaded, drilled, and unloaded one by one. This method not only takes time and effort and has low efficiency, but also is difficult to ensure the accuracy and consistency of the drilling positions and qualities on different lock tongue fixing members.

[0006] Therefore, in order to solve the problems existing in the drilling process of the lock tongue fixing member, the present invention provides a drilling processing device for automotive door lock assemblies. Summary of the Invention

Detailed implementation manner

[0035] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manner of the present invention will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation manner disclosed below.

[0036] Please refer to Figure 1 , a drilling processing device for an automobile door lock assembly, including a processing table 1, and a fixing unit 11 is arranged at the upper end of the processing table 1.

[0037] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, the fixing unit 11 includes a front side plate 111 slidably mounted on the upper end of the processing table 1 in the front-back direction. A rear side plate 112 is provided at the rear of the front side plate 111 and slidably penetrates through the processing table 1 in the up-down direction. Isosceles trapezoidal blocks 113 arranged evenly in the left-right direction are installed on both sides of the front side plate 111 and the rear side plate 112 that are close to each other. The isosceles trapezoidal blocks 113 located at the rear also slidably penetrate through the processing table 1 in the up-down direction and their height is higher than that of the isosceles trapezoidal blocks 113 at the front. A downward pulling assembly is provided at the lower end of the processing table 1 for pulling the rear side plate 112 and the rear isosceles trapezoidal block 113 to move downward synchronously. Rectangular grooves 114 arranged evenly in the left-right direction are opened at the rear end of the front side plate 111. A pressing plate 115 is slidably mounted in the rectangular grooves 114 in the up-down direction. A pull rod is mounted on the upper end of the pressing plate 115 and slidably penetrates through the front side plate 111. An adjusting spring 117 sleeved on the outside of the pull rod is connected between the groove wall of the rectangular groove 114 and the pressing plate 115. The upper ends of the pull rods arranged evenly in the left-right direction are jointly mounted with a pull plate 118.

[0038] Please refer to Figure 4 and Figure 5 , T-shaped sliding plates 120 are installed at the horizontal sections at the rear ends of the isosceles trapezoidal blocks 113 located at the front. Groove plates 121 slidably connected to the corresponding T-shaped sliding plates 120 are installed at the horizontal sections at the front ends of the isosceles trapezoidal blocks 113 located at the rear. T-shaped frames 122 are installed at the upper ends of the T-shaped sliding plates 120. Moving plates 123 are slidably mounted in the up-down direction on both sides of the leftmost and rightmost T-shaped frames 122 that are close to each other. Symmetrically arranged moving plates 123 are slidably mounted on the remaining T-shaped frames 122. Pressing plates 124 are installed at the lower ends of the moving plates 123. Connecting springs 125 located on the front and rear sides of the moving plates 123 are connected between the pressing plates 124 and the horizontal sections of the T-shaped frames 122.

[0039] Please refer to Figures 1 - 5 and Figure 9 , during specific operation: First, a plurality of tongue fixing parts 2 to be drilled need to be evenly placed on the upper end of the processing table 1 from left to right. The inclined sections of the isosceles trapezoidal plates can be adapted to the inclined sections of the octagonal tongue fixing parts 2. During this process, the pull plate 118 can be pulled upward. The pull plate 118 drives the pressing plate 115 to move upward along the rectangular groove 114 through the pull rod. At this time, the adjusting spring 117 is in a compressed state under the cooperation of the rectangular groove 114 and the pressing plate 115. After the tongue fixing part 2 fits against the rear end of the front side plate 111, the pull plate 118 can be released. At this time, the pull rod pushes the pressing plate 115 to slide downward along the rectangular groove 114 under the action of the adjusting spring 117 and finally presses against the upper front side of the tongue fixing part 2, applying a pressure to the upper end of the tongue fixing part 2 by using the pressing plate 115, which not only ensures the close fit between the tongue fixing part 2 and the front side plate 111, but also ensures the stability of the tongue fixing part 2 during subsequent movement and drilling processes, effectively preventing the movement of the tongue fixing part 2 from affecting the smooth progress of the drilling operation.

[0040] After the tongue lock fixing member 2 fits against the front side plate 111 and the front side isosceles trapezoidal clamping plate, the left and right ends of the tongue lock fixing member 2 are respectively in contact with the T-shaped sliding plates 120 on its left and right sides. The T-shaped sliding plates 120 can be used to separate adjacent tongue lock fixing members 2, preventing adjacent tongue lock fixing members 2 from interfering with each other during the drilling process and affecting the drilling quality and drilling accuracy of the tongue lock fixing members 2. With the cooperation of the isosceles trapezoidal clamping block 113 and the T-shaped sliding plates 120, the inclined section, the front end, and the left and right ends of the front side of the tongue lock fixing member 2 are all limited. In addition, the tongue lock fixing member 2 can also be pushed forward from the back to contact the front side plate 111. During this process, the left and right ends of the tongue lock fixing member 2 are respectively in contact with the rear ends of the corresponding pressing plates 124. As the tongue lock fixing member 2 moves, the pressing plate 124 pushes the moving plate 123 to move upward along the T-shaped frame 122 by compressing the connecting spring 125 until the tongue lock fixing member 2 contacts the front side plate 111. Under the action of the connecting spring 125 and the moving plate 123, the pressing plate 124 just presses on the upper end of the tongue lock fixing member 2 at this time. Pressing plates 124 are arranged on both the left and right sides of each tongue lock fixing member 2. The pressing plates 124 on both the left and right sides can be used to assist the abutting plate 115 to press the upper end of the tongue lock fixing member 2 in multiple directions, further improving the stability when fixing the tongue lock fixing member 2.

[0041] Please refer to Figure 1 and Figure 3 Figure 3

[0042] After the pressing plate 124 and the abutting plate 115 press the lock tongue fixing member 2, the rotating shaft 133 is driven to rotate clockwise by the second motor 134. The rotating shaft 133 drives the gears 132 on the left and right sides to rotate synchronously. As the gears 132 rotate, the rack 131 moves backward along the strip groove through the slide bar. Through the sliding fit between the slide bar and the strip groove, the smoothness of the front side plate 111, the isosceles trapezoidal block 113, the T-shaped slide plate 120, and the lock tongue fixing member 2 during the movement can be further improved, so as to ensure that the lock tongue fixing member 2 smoothly reaches the drilling position. The front side plate 111 drives the isosceles trapezoidal block 113 and the T-shaped slide plate 120 to move backward along the processing table 1 synchronously with the racks 131 on the left and right sides. The lock tongue fixing member 2 moves backward synchronously due to being limited. Until the rear end of the lock tongue fixing member 2 abuts against the front end of the rear side plate 112, the inclined section at the rear of the lock tongue fixing member 2 abuts against the inclined section of the rear isosceles trapezoidal block 113. At this time, the lock tongue fixing member 2 is just located at the appropriate drilling position. Under the interaction of the front side plate 111, the rear side plate 112, and the isosceles trapezoidal blocks 113 on the front and rear sides, all the lock tongue fixing members 2 are firmly limited in the circumferential direction and up and down.

[0043] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 7 ,The fixing unit 11 further includes positioning columns 135 that are evenly arranged left and right and are slidably connected to the processing table 1 up and down. The positioning columns 135 are located between the front side plate 111 and the rear side plate 112. Square grooves 136 are opened at the upper ends of the positioning columns 135. Slide columns 137 are installed at the lower ends of the outer ring surfaces of the positioning columns 135. A rotating sleeve 138 that is rotatably installed at the lower end of the processing table 1 is sleeved outside the positioning columns 135. A spiral through groove 139 that is slidably connected to the slide column 137 is opened on the rotating sleeve 138. A driving component is provided at the lower end of the rotating sleeve 138 for driving its rotation.

[0044] Please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 ,The driving component includes a transmission belt pulley 140 installed at the lower end of the rotating sleeve 138. The transmission belt pulleys 140 are connected by a belt in a transmission manner. A U-shaped frame 141 with a horizontal section rotatably connected to the lower end of the transmission belt pulley 140 is installed at the lower end of the processing table 1. The lower end of the transmission belt pulley 140 in the middle is connected to the output shaft of the first motor 142 that rotates through the horizontal section of the U-shaped frame 141. The first motor 142 is installed at the lower end of the horizontal section of the U-shaped frame 141.

[0045] Please refer to Figure 3 、 Figure 6 and Figure 7, the drop-down component includes rotating rings 143 respectively sleeved outside the leftmost and rightmost rotating sleeves 138 and fixedly connected to the corresponding sliding columns 137. The rotating rings 143 are rotatably installed at the upper end of the moving ring plate 144. The moving ring plate 144 is slidably sleeved outside the rotating sleeve 138 up and down. A connecting frame 145 is jointly installed at the lower end of the rear side plate 112 and the isosceles trapezoidal block 113 at the rear. The connecting frame 145 is installed between the upper rear sides of the left and right moving ring plates 144.

[0046] After the lock tongue fixing member 2 is completely positioned, the motor 142 can drive the middle belt pulley 140 to rotate. The middle belt pulley 140 drives the other belt pulleys 140 to rotate synchronously through the belt. The corresponding rotating sleeve 138 rotates synchronously with the belt pulley 140. During this process, the positioning post 135 moves upward along the rotating sleeve 138 and the processing table 1 through the cooperation between the sliding column 137 and the spiral through groove 139. At the same time, the rotating ring 143 moves upward and rotates along the outer ring surface of the rotating sleeve 138 synchronously with the corresponding sliding column 137. The moving ring plate 144 drives the positioning post 135 to move upward along the rotating sleeve 138 synchronously with the rotating ring 143. The rear side plate 112 and the isosceles trapezoidal block 113 at the rear move upward synchronously with the left and right moving ring plates 144 through the connecting frame 145 until the positioning post 135 passes through the middle circular hole of the corresponding lock tongue fixing member 2. Through the cooperation between the positioning post 135 and the middle circular hole of the lock tongue fixing member 2, the drilling position of the lock tongue fixing member 2 can be further positioned, so as to ensure the accuracy of the drilling position and the forming quality of the drilling. The T-shaped slide plate 120 can limit the upward moving chute plate 121. The chute plate 121 can assist the T-shaped slide plate 120 to better limit the left and right ends of the lock tongue fixing member 2. At the same time, the cooperation between the T-shaped slide plate 120 and the chute plate 121 can realize mutual locking and fixation, so as to improve the stable reliability of the front side plate 111, the rear side plate 112 and the front and rear isosceles trapezoidal blocks 113 clamping and fixing the lock tongue fixing member 2. The rear side plate 112 and the isosceles trapezoidal block 113 at the rear always keep the contact limit on the lock tongue fixing member 2. The upper end of the positioning post 135 is flush with the processing table 1 in the initial state, which will not affect the movement of the lock tongue fixing member 2, and the upper end surfaces of the rear side plate 112 and the isosceles trapezoidal block 113 at the rear are located above the upper end surface of the processing table 1.

[0047] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 8, both left and right ends of the processing table 1 are equipped with cylinders 151. The upper ends of the pushing ends of the left and right cylinders 151 are jointly equipped with a mounting plate 152. The lower end of the mounting plate 152 is provided with an automatic drill 153. The lower end of the automatic drill 153 is provided with symmetrically arranged drills on the left and right. Circular through holes that are symmetrically arranged on the left and right and are used for the drills to drill holes are opened at corresponding positions on the processing table 1 between adjacent T-shaped sliding plates 120. An existing driving source can drive the automatic drill 153 to move left and right along the mounting plate 152 (the driving source is not shown in the figure). A circular sleeve 154 that is slidably matched with the positioning column 135 is installed in the middle of the lower end of the automatic drill 153. A square block 155 that is slidably matched with the square groove 136 is installed at the lower end of the top wall of the circular sleeve 154. A spring telescopic rod 156 is installed at the lower end of the rear side of the automatic drill 153. The lower end of the spring telescopic rod 156 is installed with an auxiliary plate 157.

[0048] After the fixing and positioning of the lock tongue fixing member 2 are completed, an existing driving source can be used to drive the automatic drill 153 and the drill to move from left to right along the mounting plate 152. Moreover, the positions of the left and right drills have been adjusted in advance according to the required positions of the left and right screw mounting holes on the lock tongue fixing member 2. When the automatic drill 153 reaches above the leftmost lock tongue fixing member 2 and the left and right drills are respectively opposite to the corresponding circular through holes, the mounting plate 152, the automatic drill 153 and the drill can be pushed downward integrally by the cylinders 151 on both sides. During the downward movement of the automatic drill 153 and the drill, the circular sleeve 154 gradually slides and sleeves outside the positioning column 135, and the square block 155 gradually slidably cooperates with the square groove 136 opened at the upper end of the positioning column 135. By using the cooperation between the circular sleeve 154, the positioning column 135, the square block 155 and the square groove 136, the automatic drill 153 during downward drilling can be supported and guided, ensuring that the drill of the automatic drill 153 always remains stable during the drilling process, thereby improving the drilling efficiency and ensuring the quality and accuracy of the drilling.

[0049] In addition, the spring telescopic rod 156 drives the auxiliary plate 157 to move downward synchronously with the automatic drilling machine 153. Before the drill bit drills the tongue fixing part 2, the auxiliary plate 157 first contacts the upper end of the rear side of the tongue fixing part 2. As the automatic drilling machine 153 continues to move downward, the spring telescopic rod 156 is gradually compressed and presses against the upper end of the rear side of the tongue fixing part 2 through the auxiliary plate 157. After the drill bit reaches the drilling position, the drill bits on the left and right sides are controlled by the automatic drilling machine 153 to drill screw mounting holes in the upper end of the tongue fixing part 2 at the same time. During this process, the auxiliary plate 157 always applies a pressing force to the upper end of the rear side of the tongue fixing part 2. Through the cooperation between the auxiliary plate 157, the pressing plate 115 and the pressing plate 124, the tongue fixing part 2 during the drilling process can be further fixed in multiple directions downward, effectively preventing the tongue fixing part 2 from deflecting up and down during the drilling process, resulting in the deviation of the drilling position, and at the same time avoiding the deformation of the tongue fixing part 2 due to the impact force of the drill bit, thereby improving the forming quality of the screw mounting hole. After the screw mounting hole on the leftmost tongue fixing part 2 is formed, the installation plate 152 and the automatic drilling machine 153 can be pushed upward away from the positioning column 135 by the air cylinders 151 on the left and right sides. Then, the automatic drilling machine 153 can be driven to move to the right again by the existing driving source, and so on, until the automatic drilling machine 153 controls the drilling to complete the drilling of all the tongue fixing parts 2.

[0050] After all the drilling is completed, the installation plate 152, the automatic drilling machine 153 and the drill bit are reset. Subsequently, the middle transmission belt pulley 140 can be driven by the first motor 142 to rotate in the reverse direction, and the remaining transmission belt pulleys 140 rotate synchronously through the belt. Under the cooperation of the rotating sleeve 138, the spiral through groove 139 and the sliding column 137, the positioning column 135 moves downward along the processing table 1 and the rotating sleeve 138 to reset away from the processing table 1. The rotating ring 143 drives the moving ring plate 144 to move downward along the rotating sleeve 138 synchronously. At the same time, the moving ring plates 144 on the left and right sides drive the rear side plate 112, the rear isosceles trapezoidal clamping block 113 and the chute plate 121 to move downward along the processing table 1 synchronously through the connecting frame 145 until the positioning column 135, the rear side plate 112, the rear isosceles trapezoidal clamping block 113 and the chute plate 121 are reset to be all away from the processing table 1. At this time, the rear side plate 112 and the rear isosceles trapezoidal clamping block 113 do not interfere with the movement of the subsequent tongue fixing parts 2.

[0051] Finally, the front side plate 111 and the drilled tongue fixing part 2 can be pushed backward together. After the tongue fixing part 2 is separated from the processing table 1, it falls into the existing collection area under the action of gravity for unified collection (the collection area is not shown in the figure), and the drilled tongue fixing part 2 can be obtained (such as Figure 9As shown in the figure, by using the method of positioning and clamping multiple lock tongue fixing parts 2 at one time, drilling holes in sequence, and unified blanking, not only can the number of operations and time be reduced, the production efficiency be improved, but also the drilling processing accuracy and consistency of each lock tongue fixing part 2 can be guaranteed, thereby improving its quality.

[0052] Please refer to Figure 3 , Figure 6 and Figure 8 , fixed rods are installed at both the front and rear ends of the automatic drilling machine 153. A support column 158 is installed at the lower end of the fixed rod. A cylindrical groove is opened at the lower end of the support column 158. A limit column 161 is slidably installed up and down in the cylindrical groove. A ball is rotatably installed at the lower end of the limit column 161. A telescopic spring 162 is connected between the upper end of the limit column 161 and the inner wall of the top of the cylindrical groove. Horizontal plates 163 are symmetrically arranged in the front and rear on the processing table 1. The front side plate 111 and the rear side plate 112 are located between the front and rear horizontal plates 163. The horizontal plates 163 penetrate through the processing table 1 up and down and are fixedly connected to the moving ring plates 144 on the left and right sides. A horizontal groove 164 is opened at the upper end of the horizontal plate 163. Hemispherical grooves 165 are evenly arranged left and right at the upper end of the bottom wall of the horizontal groove 164.

[0053] During the process of the automatic drilling machine 153 moving along the mounting plate 152, the fixed rod drives the support column 158 to move synchronously. The support column 158 drives the limit column 161 and the ball at its lower end to move along the horizontal groove 164 through the telescopic spring 162. The movement of the automatic drilling machine 153 can be guided through the cooperation between the support column 158, the limit column 161 and the horizontal groove 164. During the up and down movement of the mounting plate 152 and the automatic drilling machine 153, the limit column 161 can always contact the horizontal groove 164 through the ball under the action of the telescopic spring 162. However, in the initial state, the automatic drilling machine 153 drives the support column 158 and the limit column 161 to be located at positions far from the upper end of the processing table 1, and the limit column 161 does not interfere with the feeding, clamping and fixing of the lock tongue fixing part 2.

[0054] When the automatic drill 153 drives the left and right drills to move to directly above the corresponding circular through-hole, the ball at the lower end of the limit post 161 just snaps into the corresponding hemispherical groove 165 on the bottom wall of the transverse groove 164. When the automatic drill 153 continues to move to the next drilling position, the ball is pulled and separated from the hemispherical groove 165. During the separation, the limit post 161 compresses the telescopic spring 162 and moves upward along the cylindrical groove. The cooperation between the ball and the hemispherical groove 165 can limit the movement of the automatic drill 153, thereby ensuring that the drill can accurately drill the lock tongue fixing part 2, improving the accuracy and consistency of the positions and forming qualities of the screw mounting holes on different lock tongue fixing parts 2. In addition, during the process of the positioning post 135 and the rear side plate 112 moving up and down along the processing table 1, the transverse plates 163 on the front and rear sides also move up and down along the processing table 1 with the moving ring plate 144, so as to ensure that the transverse plates 163 on the front and rear sides will not affect the loading, unloading, clamping and fixing of the lock tongue fixing part 2.
