Description

Technical Field

[0001] The invention relates to the field of processing of automobile door lock components, in particular to a drilling processing device for automobile door lock components. Background Art

[0002] The car door lock assembly is a device used to lock and unlock the car door. It is mainly composed of a door lock actuator, an electronic control unit, and a door lock mechanism. The door lock mechanism includes a door lock pin, a lock tongue fixing, a lock catch, and other components. The lock tongue fixing usually refers to a component used to fix and control the lock tongue. It is an indispensable part of the door lock mechanism and has high durability and reliability. The common lock tongue fixing is octagonal in shape, with a middle circular hole in the middle for installing and fixing the lock tongue. The lock tongue fixing is also provided with two screw mounting holes on both sides of the middle circular hole (such as Fig. 9 As shown), the screw mounting hole can be used with a screw to fix the lock tongue fixing member, and the screw mounting hole is usually formed by drilling.

[0003] However, there are still the following problems in the process of drilling the screw mounting holes for the bolt fixing parts: (1) Since the lock tongue fixing is small and thin, it is difficult to position and clamp it firmly. The lock tongue fixing is prone to displacement during drilling, which affects the quality and accuracy of the drilling. At the same time, it is difficult for the lock tongue fixing to maintain an accurate position and direction during the drilling process, resulting in poor consistency in the drilling position and size.

[0035] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The fixing unit 11 includes a front side plate 111 which is slidably mounted on the upper end of the processing table 1. A rear side plate 112 which slides up and down and penetrates the processing table 1 is arranged on the rear side of the front side plate 111. The side close to the front side plate 111 and the rear side plate 112 is equipped with isosceles trapezoidal blocks 113 which are evenly arranged on the left and right. The isosceles trapezoidal blocks 113 on the rear side also slide up and down and penetrate the processing table 1. The height of the isosceles trapezoidal blocks 113 on the rear side is higher than that of the isosceles trapezoidal blocks 113 on the front side. The lower end of the processing table 1 is provided with a The rear side plate 112 is movable and moves downward synchronously with the rear isosceles trapezoidal block 113. The rear end of the front side plate 111 is provided with rectangular grooves 114 which are evenly arranged on the left and right. A support plate 115 is installed inside the rectangular groove 114 for sliding up and down. A pull rod sliding through the front side plate 111 is installed on the upper end of the support plate 115. An adjustment spring 117 mounted on the outside of the pull rod is connected between the groove wall of the rectangular groove 114 and the support plate 115. A pull plate 118 is installed on the upper ends of the pull rods which are evenly arranged on the left and right.

[0036] See also Figure 4 and Figure 5 The rear end horizontal sections of the isosceles trapezoidal blocks 113 on the front side are all installed with T-shaped slide plates 120, and the front end horizontal sections of the isosceles trapezoidal blocks 113 on the rear side are all installed with slide groove plates 121 slidably connected to the corresponding T-shaped slide plates 120, and a T-shaped frame 122 is installed on the upper end of the T-shaped slide plate 120. The sides close to the leftmost and rightmost T-shaped frames 122 are both slidably installed with moving plates 123, and the remaining T-shaped frames 122 are all slidably installed with left-right symmetrical moving plates 123, and a pressing plate 124 is installed at the lower end of the moving plate 123, and connecting springs 125 located on the front and rear sides of the moving plate 123 are connected between the pressing plate 124 and the horizontal section of the T-shaped frame 122.

[0037] See also Figure 1-5 and Fig. 9 , when working specifically: first, multiple bolt fixings 2 to be drilled need to be evenly placed from left to right on the upper end of the processing table 1, and the inclined section of the isosceles trapezoidal card plate can be adapted to the inclined section of the octagonal bolt fixing 2. During this process, the pull plate 118 can be pulled upward, and the pull plate 118 drives the abutment plate 115 to move upward along the rectangular groove 114 through the pull rod. At this time, the adjustment spring 117 is in a compressed state under the cooperation of the rectangular groove 114 and the abutment plate 115, and the bolt fixing 2 is attached to the front side plate. After the rear end of 111 is reached, the pull plate 118 can be loosened. At this time, the pull rod pushes the push plate 115 to slide downward along the rectangular groove 114 under the action of the adjusting spring 117 and finally presses against the upper end of the front side of the lock tongue fixing member 2. The push plate 115 is used to apply a pressure to the upper end of the lock tongue fixing member 2, which not only ensures that the lock tongue fixing member 2 is tightly fitted with the front side plate 111, but also ensures the stability of the lock tongue fixing member 2 in the subsequent movement process and the drilling process, effectively preventing the lock tongue fixing member 2 from moving and affecting the smooth progress of the drilling operation.

[0038] After the lock tongue fixing part 2 is fitted with the front side plate 111 and the front isosceles trapezoidal card plate, the left and right ends of the lock tongue fixing part 2 are respectively fitted with the T-shaped slide plates 120 on its left and right sides. The T-shaped slide plates 120 can be used to separate adjacent lock tongue fixing parts 2 to avoid mutual interference between adjacent lock tongue fixing parts 2 during the drilling process and affect the drilling quality and drilling accuracy of the lock tongue fixing part 2. With the cooperation of the isosceles trapezoidal card block 113 and the T-shaped slide plate 120, the inclined section, front end and left and right ends of the front side of the lock tongue fixing part 2 are limited. In addition, the lock tongue fixing part 2 can also be pushed from back to front until it contacts the front side plate 111. In this process, the lock tongue The left and right ends of the fixing member 2 respectively conflict with the rear ends of the corresponding pressure plates 124. As the lock tongue fixing member 2 moves, the pressure plate 124 pushes the movable plate 123 to move upward along the T-shaped frame 122 by compressing the connecting spring 125 until the lock tongue fixing member 2 conflicts with the front side plate 111. Under the action of the connecting spring 125 and the movable plate 123, the pressure plate 124 at this time is just pressed on the upper end of the lock tongue fixing member 2. Each lock tongue fixing member 2 is provided with a pressure plate 124 on both sides. The pressure plates 124 on the left and right sides can assist the pressure plate 115 to perform multi-directional pressure on the upper end of the lock tongue fixing member 2, thereby further improving the stability when fixing the lock tongue fixing member 2.

[0039] See also Figure 1 and Figure 3 The left and right ends of the front side plate 111 are both equipped with racks 131, and a slide bar is installed at the lower end of the rack 131. A bar groove that is symmetrical on the left and right and slidably connected to the corresponding slide bar is opened on the upper end of the processing table 1. A gear 132 is meshed on the upper end of the rack 131. A vertical plate that is symmetrical on the left and right is installed on the upper end of the processing table 1. A rotating shaft 133 fixedly connected to the gear 132 is rotatably installed between the left and right vertical plates. The right end of the rotating shaft 133 passes through the vertical plate on the right and is connected to the output shaft of the second motor 134. The second motor 134 is fixedly connected to the right vertical plate.

[0040] After the pressing plate 124 and the abutting plate 115 press the bolt fixing part 2, the motor 134 drives the rotating shaft 133 to rotate clockwise, and 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. The sliding cooperation between the slide bar and the strip groove can further improve the stability of the front side plate 111, the isosceles trapezoidal block 113, the T-shaped slide plate 120 and the bolt fixing part 2 during the movement, thereby ensuring that the bolt fixing part 2 reaches the drilling position smoothly; the front side plate 111 drives the isosceles trapezoidal block 113, the T-shaped slide plate 120 and the bolt fixing part 2 to rotate clockwise. The trapezoidal block 113 and the T-shaped slide plate 120 move backward along the processing table 1 synchronously with the racks 131 on the left and right sides, and the lock tongue fixing member 2 moves backward synchronously due to the limitation, until the rear end of the lock tongue fixing member 2 conflicts with the front end of the rear side plate 112, and the inclined section on the rear side of the lock tongue fixing member 2 conflicts with the inclined section of the rear isosceles trapezoidal block 113. At this time, the lock tongue fixing member 2 is just located at a suitable 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.

[0041] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The fixing unit 11 also includes positioning columns 135 that are evenly arranged on the 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. A square groove 136 is provided at the upper end of the positioning columns 135. A sliding column 137 is installed at the lower end of the outer ring surface of the positioning columns 135. The outer part of the positioning columns 135 is sleeved with a rotating sleeve 138 rotatably installed at the lower end of the processing table 1. The rotating sleeve 138 is provided with a spiral groove 139 slidably connected to the sliding column 137. A driving component for driving the rotating sleeve 138 to rotate is provided at the lower end of the rotating sleeve 138.

[0042] See also Figure 1 , Figure 2 , Figure 6 and Figure 7 The driving assembly includes a transmission pulley 140 installed at the lower end of a rotating sleeve 138, and the transmission pulleys 140 are connected to each other through a belt transmission. A horizontal section of a C-shaped frame 141 is installed at the lower end of the processing table 1, and the lower end of the transmission pulley 140 is rotatably connected to the lower end of the transmission pulley 140. The lower end of the transmission pulley 140 located in the middle is connected to the output shaft of a motor 142 that rotates through the horizontal section of the C-shaped frame 141, and the motor 142 is installed at the lower end of the horizontal section of the C-shaped frame 141.

[0043] See also Figure 3 , Figure 6 and Figure 7The pull-down assembly includes a rotating ring 143 that is respectively sleeved on the outside of the leftmost and rightmost rotating sleeves 138 and fixedly connected to the corresponding sliding column 137. The rotating ring 143 is rotatably installed on the upper end of the movable ring plate 144. The movable ring plate 144 is slidably sleeved on the outside of the rotating sleeve 138 up and down. The rear side plate 112 and the lower end of the isosceles trapezoidal block 113 located on the rear side are jointly installed with a connecting frame 145, and the connecting frame 145 is installed between the rear upper ends of the left and right movable ring plates 144.

[0044] After the lock tongue fixing part 2 is completely positioned, the transmission pulley 140 in the middle can be driven to rotate by the motor 142, and the middle transmission pulley 140 drives the other transmission pulleys 140 to rotate synchronously through the belt, and the corresponding rotating sleeve 138 rotates synchronously with the transmission pulley 140. In this process, the positioning column 135 moves upward along the rotating sleeve 138 and the processing table 1 through the cooperation between the sliding column 137 and the spiral groove 139. At the same time, the rotating ring 143 moves up and rotates along the outer ring surface of the rotating sleeve 138 synchronously with the corresponding sliding column 137, and the moving ring plate 144 drives the positioning column 135 to move upward along the rotating sleeve 138 synchronously with the rotating ring 143, and the rear side plate 112 and the rear isosceles trapezoidal block 113 move upward synchronously with the left and right moving ring plates 144 through the connecting frame 145 until the positioning column 135 is positioned. The positioning column 135 passes through the middle circular hole of the corresponding lock tongue fixing piece 2. The drilling position of the lock tongue fixing piece 2 can be further positioned by the cooperation between the positioning column 135 and the middle circular hole of the lock tongue fixing piece 2, thereby ensuring the accuracy of the drilling position and the molding quality of the drilling hole. The T-shaped slide plate 120 can be used to limit the slide plate 121 during the upward movement process. The slide plate 121 can assist the T-shaped slide plate 120 to better limit the left and right ends of the lock tongue fixing piece 2. At the same time, the cooperation between the T-shaped slide plate 120 and the slide plate 121 can achieve mutual locking and fixation, thereby improving the stability and reliability of the front side plate 111, the rear side plate 112 and the front and rear isosceles trapezoidal blocks 113 in clamping and fixing the lock tongue fixing piece 2. The rear side plate 112 and the rear isosceles trapezoidal block 113 always maintain the resistance limit to the lock tongue fixing piece 2. In the initial state, the upper end of the positioning column 135 is flush with the processing table 1 and 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 rear isosceles trapezoidal block 113 are located above the upper end surface of the processing table 1 .

[0045] See also Figure 1 , Figure 2 , Figure 3 and Figure 8, cylinders 151 are installed at both ends of the processing table 1, and a mounting plate 152 is installed on the upper ends of the pushing ends of the left and right cylinders 151. An automatic drilling machine 153 is arranged at the lower end of the mounting plate 152, and a left-right symmetrical drill bit is arranged at the lower end of the automatic drilling machine 153. The positions between the adjacent T-shaped slide plates 120 on the processing table 1 are provided with left-right symmetrical circular through holes for drilling holes by the drill bit. The automatic drilling machine 153 can be driven to move left and right along the mounting plate 152 by an existing driving source (the driving source is not shown in the figure), and a circular sleeve 154 that slides with the positioning column 135 is installed in the middle of the lower end of the automatic drilling machine 153, and a square block 155 that slides 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 drilling machine 153, and an auxiliary plate 157 is installed at the lower end of the spring telescopic rod 156.

[0046] After the fixing and positioning of the bolt fixing member 2 is completed, the automatic drill 153 and the drill bit can be driven by the existing driving source to move from left to right along the mounting plate 152, and the positions of the left and right drill bits have been adjusted in advance according to the required positions of the left and right screw mounting holes on the bolt fixing member 2. When the automatic drill 153 reaches the top of the leftmost bolt fixing member 2 and the left and right drill bits are respectively opposite to the corresponding circular through holes, the mounting plate 152, the automatic drill 153 and the drill bit can be pushed downward as a whole by the cylinders 151 on the left and right sides. As the drill bit moves downward, the circular sleeve 154 gradually slides and is mounted on the outside of the positioning column 135, and the square block 155 gradually slides and cooperates with the square groove 136 opened at the upper end of the positioning column 135. By utilizing the cooperation between the circular sleeve 154, the positioning column 135, the square block 155 and the square groove 136, the automatic drilling rig 153 can be supported and guided when drilling downward, ensuring that the drill bit of the automatic drilling rig 153 always remains stable during the drilling process, thereby improving the drilling efficiency and ensuring the quality and accuracy of the drilling.

[0047] 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 lock tongue fixing member 2, the auxiliary plate 157 first contacts the upper end of the rear side of the lock tongue fixing member 2. As the automatic drilling machine 153 continues to move downward, the spring telescopic rod 156 is gradually compressed and pressed against the upper end of the rear side of the lock tongue fixing member 2 through the auxiliary plate 157. After the drill bit reaches the drilling position, the automatic drilling machine 153 controls the drill bits on the left and right sides to simultaneously drill screw installation holes on the upper end of the lock tongue fixing member 2. During the drilling process, the auxiliary plate 157 always applies a resisting force to the upper end of the rear side of the lock tongue fixing member 2. Through the cooperation between the auxiliary plate 157, the resisting plate 115 and the pressing plate 124, the lock tongue fixing member 2 can be further pressed down and fixed in multiple directions during the drilling process, effectively preventing the lock tongue fixing member 2 from moving up and down during the drilling process, which causes the drilling position to shift. At the same time, it can prevent the lock tongue fixing member 2 from being deformed by 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 lock tongue fixing member 2 is formed, the cylinders 151 on the left and right sides can push the mounting plate 152 and the automatic drilling machine 153 to move up away from the positioning column 135, and then the automatic drilling machine 153 can be driven to move 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 lock tongue fixing members 2.

[0048] After all the holes are drilled, the mounting plate 152, the automatic drilling machine 153 and the drill bit are reset, and then the middle transmission pulley 140 can be driven by the motor 142 to rotate in the opposite direction, and the other transmission pulleys 140 are synchronously rotated through the belts. Under the cooperation of the rotating sleeve 138, the spiral groove 139 and the sliding column 137, the positioning column 135 moves down along the processing table 1 and the rotating sleeve 138 to reset away from the processing table 1, and the rotating ring 143 drives the moving ring plate 144 to rotate along the rotating sleeve 138 moves downward synchronously, and at the same time, the movable ring plates 144 on the left and right sides drive the rear side plates 112, the rear isosceles trapezoidal block 113 and the slide plate 121 to move downward synchronously along the processing table 1 through the connecting frame 145, until the positioning column 135, the rear side plate 112, the rear isosceles trapezoidal block 113 and the slide plate 121 are reset to be away from the processing table 1. At this time, the rear side plate 112 and the rear isosceles trapezoidal block 113 do not interfere with the subsequent movement of the lock tongue fixing member 2.

[0049] Finally, the front side plate 111 and the bolt fixing member 2 after drilling can be pushed backward together, and the bolt fixing member 2 will fall to the existing collection area under the action of gravity after leaving the processing table 1 for unified collection (the collection area is not shown in the figure), so that the bolt fixing member 2 after drilling (such as Fig. 9As shown), the method of positioning and clamping multiple lock tongue fixing parts 2 at one time, drilling holes in sequence and cutting materials uniformly can not only reduce the number of operations and time, improve production efficiency, but also ensure the drilling accuracy and consistency of each lock tongue fixing part 2, thereby improving its quality.

[0050] See also Figure 3 , Figure 6 and Figure 8 The front and rear ends of the automatic drilling machine 153 are both equipped with fixing rods, and the lower end of the fixing rod is equipped with a supporting column 158. The lower end of the supporting column 158 is provided with a cylindrical groove, and a limiting column 161 is slidably installed in the cylindrical groove, and a ball is rotatably installed at the lower end of the limiting column 161. A telescopic spring 162 is connected between the upper end of the limiting column 161 and the inner wall of the top of the cylindrical groove. A front-to-back symmetrical transverse plate 163 is provided on the processing table 1, and the front side plate 111 and the rear side plate 112 are located between the front and rear transverse plates 163. After the transverse plate 163 slides up and down and penetrates the processing table 1, it is fixedly connected to the movable ring plates 144 on the left and right sides. A transverse groove 164 is provided on the upper end of the transverse plate 163, and a hemispherical groove 165 evenly arranged on the left and right is provided on the upper end of the bottom wall of the transverse groove 164.

[0051] During the movement of the automatic drilling machine 153 along the mounting plate 152, the fixing rod drives the support column 158 to move synchronously therewith, and the support column 158 drives the limit column 161 and the ball at its lower end to move along the transverse groove 164 through the telescopic spring 162. The movement of the automatic drilling machine 153 can be guided by the cooperation among the support column 158, the limit column 161 and the transverse groove 164. During the movement of the mounting plate 152 and the automatic drilling machine 153 up and down, the limit column 161 can always contact the transverse 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 through the fixing rod to be located away from the upper end of the processing table 1, and the limit column 161 will not interfere with the loading and unloading and clamping of the lock tongue fixing member 2.

[0052] When the automatic drilling machine 153 drives the left and right drill bits to move to the position directly above the corresponding circular through hole, the ball at the lower end of the limiting column 161 is just stuck in the corresponding hemispherical groove 165 on the bottom wall of the transverse groove 164. When the automatic drilling machine 153 continues to move to the next drilling position, the ball is pulled and separated from the hemispherical groove 165. During the separation, the limiting column 161 compresses the telescopic spring 162 and moves upward along the cylindrical groove. The cooperation between the ball and the hemispherical groove 165 can control the position of the automatic drilling machine 153. The movement is limited to ensure that the drill bit can accurately drill holes in the lock tongue fixing member 2, thereby improving the accuracy and consistency of the screw mounting hole positions and molding quality on different lock tongue fixing members 2. In addition, in the process of the positioning column 135 and the rear side plate 112 moving up and down along the processing table 1, the front and rear side transverse plates 163 also move up and down along the processing table 1 with the moving ring plate 144, thereby ensuring that the front and rear side transverse plates 163 will not affect the loading and unloading and clamping of the lock tongue fixing member 2.
