Description

Technical Field

[0001] The invention relates to the field of processing of diesel engine parts, in particular to a post-casting processing device for diesel engine parts. Background Art

[0002] Gears are one of the important parts of the diesel engine transmission system. They are used to transmit power and rotation, control the running speed and coordination of different components. The gears of diesel engines are generally cast and formed by iron and its alloy materials. The casting process can meet the requirements for gear strength and wear resistance. After casting, the gears also need to go through deburring, heat treatment, drilling, turning, grinding, polishing and other steps. Drilling is one of the most important processing steps. When the gear has a mounting circular hole for mounting the gear shaft and a prefabricated circular hole that is symmetrical about the mounting circular hole, it is also necessary to drill two left-right symmetrical processing holes on the gear to obtain the final required gear.

[0003] However, there are still the following problems in the process of drilling gears: 1. Before drilling the gear, it is generally necessary to manually adjust the gear to the appropriate drilling position. This method is not only time-consuming and labor-intensive, but also has low overall work efficiency. It is also easily affected by human subjective factors, resulting in poor accuracy of the gear drilling position and difficulty in ensuring the drilling quality.

[0004] 2.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] See also Figure 1 and Fig.11 A diesel engine parts casting post-processing equipment includes a processing round table 1, both sides of the processing round table 1 are equipped with fixed brackets, and the upper end of the processing round table 1 is provided with an inner fixing component 11 and an outer fixing component 12.

[0035] See also Figure 1 , Figure 2 , Figure 3 , Figure 7 and Fig. 9 The internal fixing component 11 includes a placement ring 111 rotatably mounted at the center of the upper end of the processing truncated table 1, a connecting plate 113 is connected to the inner side of the placement ring 111, a motor 112 is mounted at the lower end of the processing truncated table 1, the output shaft of the motor 112 rotates through the processing truncated table 1 and is connected to the center of the lower end of the connecting plate 113, a positioning rod 114 is mounted at the center of the upper end of the connecting plate 113, and a circular through hole 154 which is symmetrical on both sides and used for drilling processing is opened on the processing truncated table 1.

[0036] See also Figure 3 , Figure 7 , Figure 8 and Fig. 9 A pressure plate 115 is provided above the placement ring 111, which slides up and down and penetrates the positioning rod 114. A front-to-back symmetrical pressure column 117 is installed at the lower end of the pressure plate 115. A lever 118 is installed at both the front and rear ends of the pressure plate 115. Two concentric arc plates 119 arranged inside and outside are installed at the upper ends of the front and rear sides of the pressure plate 115. A vertical through groove is provided on the arc plate 119 located on the outer side. Two adjustment rods 120 arranged left and right are installed at the lower ends of the front and rear sides of the pressure plate 115. The length of the adjustment rod 120 is greater than the length of the pressure column 117 and is located on the outer side of the pressure column 117. A socket 153 corresponding to the adjustment rod 120 is provided at the upper end of the placement ring 111. A circumferentially evenly arranged abutment plate 121 is provided on the outside of the adjustment rod 120. The lower end of the abutment plate 121 is inclined in the direction close to the adjustment rod 120, and an adjustment spring 122 evenly arranged up and down is connected between the abutment plate 121 and the outer ring surface of the adjustment rod 120.

[0037] During operation: before drilling the gear, the gear to be drilled needs to be placed on the upper end of the placement ring 111, and the positioning rod 114 is passed through the mounting circular hole in the middle of the gear, but there is a certain gap between the positioning rod 114 and the gear mounting circular hole. At this time, the gear is still in an active state. Since it is difficult to ensure that the placed gear is in the accurate drilling position, the motor 112 can drive the placement ring 111 and the positioning rod 114 to rotate slowly through the connecting plate 113, and the placement ring 111 drives the gear to rotate synchronously until the gear rotates to a suitable drilling position. At this time, the positions to be drilled on the left and right sides of the gear are opposite to the corresponding circular through holes 154 on the processing table 1, but there is still a certain deviation between the two.

[0038] Subsequently, the pressure plate 115 can be placed on the upper end of the gear from top to bottom, and the positioning rod 114 can pass through the pressure plate 115. The subsequent pressure plate 115 can drive the adjustment rod 120 to move downward. The adjustment rod 120 first drives the abutment plate 121 to move downward synchronously through the adjustment spring 122. When moving downward, the abutment plate 121 first contacts the tooth groove of the gear through the inclined section at its lower end. Under the action of the adjustment spring 122, the abutment plate 121 can adaptively maintain a state of contact with the tooth groove of the gear. The gear is squeezed by the abutment plate 121 and can rotate slightly around the positioning rod 114 until the adjustment rod 120 can be smoothly Inserted into the insertion hole 153, the position adjustment of the gear is completed at this time, so that the position of the hole to be drilled on the gear is opposite to the circular through hole 154. By automatically adjusting and correcting the position of the gear, the preparation time before drilling can be greatly reduced, which is beneficial to improving the drilling efficiency. Since the adjustment rod 120 is longer than the pressure column 117, after the position correction of the gear is completed, the front and rear pressure columns 117 are simultaneously inserted into the front and rear prefabricated circular holes of the gear to limit the circumference of the gear, so as to prevent the corrected gear from rotating under the influence of external factors and affecting the smooth progress of subsequent drilling.

[0039] See also Figure 3 and Figure 4 The external fixing assembly 12 includes a fixing ring 123 installed at the upper end of the processing table 1, and a block 124 which is symmetrical and matched with the lever 118 is installed at the upper end of the fixing ring 123. An outer push rod 125 arranged evenly in the circumferential direction is arranged on the inner side of the fixing ring 123. A moving assembly for controlling the outer push rod 125 to synchronously move along the radial direction of the processing table 1 is arranged on the upper end of the processing table 1; the moving assembly includes a rack 126 which slides evenly in the circumferential direction through the fixing ring 123 and is fixedly connected to the corresponding outer push rod 125. One side of the fixing ring 123 radially extending from the rack 126 is meshed with a gear column 127 rotatably connected to the processing table 1. The circumferentially arranged gear column 127 is meshed with an inner gear ring 128 located on the outer side of the rack 126 and rotatably connected to the processing table 1. The lower end of the front gear column 127 is connected to the output shaft of the motor 2 129 which rotates through the processing table 1, and the motor 2 129 is installed at the lower end of the processing table 1.

[0040] During operation: when the pressure plate 115 is placed on the upper end of the gear, the pressure plate 115 can drive the front and rear levers 118 to overlap and cooperate with the corresponding lever blocks 124, so as to improve the relative stability between the pressure plate 115 and the fixing ring 123. After completing the pre-limiting of the upper end and the circumference of the gear, the motor 2 129 can be used to drive the gear column 127 located on the front side to rotate, and the gear column 127 located on the front side drives the other gear columns 127 to rotate synchronously through the inner gear ring 128. While the gear column 127 rotates, it can drive the rack 126 and the outer push rod 125 to move radially along the fixing ring 123 toward the direction where the gear is located until the outer push rod 125 is tightly pressed against the tooth groove of the gear. The outer push rods 125 evenly arranged circumferentially are used to apply a pressing force to the gear at the same time, which can not only improve the fixing efficiency, but also make the gear completely in a circumferentially fixed state, effectively increasing the stability of the gear during drilling processing, and avoiding the gear from shaking during the subsequent drilling process and affecting the processing quality and processing accuracy.

[0041] See also Figure 1-Figure 6 The side of the outer push rod 125 close to the center of the processing truncated table 1 is hinged with an auxiliary push rod 130 symmetrical to the outer push rod 125. The side of the auxiliary push rod 130 close to the outer push rod 125 is hinged with a connecting rod 131 sliding through the side wall of the outer push rod 125 through a pin shaft, and the pin shaft is slidably connected to the auxiliary push rod 130. A push rod 132 is slidably installed inside the outer push rod 125. The end of the push rod 132 away from the rack 126 is equipped with a truncated table section slidably connected to the end of the connecting rod 131. The rack 126 is internally threaded with a threaded column 133 rotatably connected to the corresponding push rod 132. The end of the threaded column 133 away from the push rod 132 is equipped with an adjusting gear 134. One side of the adjusting gear 134 is meshed with The toothed plate 135 is movable through the processing truncated table 1, and is slidably connected to the rack 126 up and down through a connecting frame. A T-shaped push plate 136 located below the processing truncated table 1 is provided at the lower end of the toothed plate 135. A slide groove for the toothed plate 135 to slide radially along the processing truncated table 1 is provided on the horizontal section of the T-shaped push plate 136. The lower end of the vertical section of the circumferentially arranged T-shaped push plate 136 is fixedly connected to the same circular tray 137. A fixed seat is provided below the circular tray 137. The center of the lower end of the circular tray 137 is connected to the pushing end of a cylinder 138 installed at the upper end of the fixed seat. A circumferentially evenly arranged guide telescopic rod 139 is connected between the circular tray 137 and the fixed seat, and a fixed bracket is installed at the upper end of the fixed seat.

[0042] During operation: when the outer push rod 125 enters the tooth groove of the gear but does not touch the tooth groove, the circular tray 137 can be pushed upward by the cylinder 138, and the guide telescopic rod 139 is extended accordingly. The guide telescopic rod 139 can be used to guide and support the circular tray 137 during the movement, and the circular tray 137 drives the circumferentially arranged T-shaped push plates 136 to move upward synchronously, and the T-shaped push plates 136 drive the toothed plate 135 to move upward along the connecting frame, and in the process of the movement of the rack 126, the toothed plate 135 can move synchronously along the slide groove on the T-shaped push plate 136 through the connecting frame, and the toothed plate 135 drives the adjusting gear 134 to rotate when moving upward, and the adjusting gear 134 drives the screw The threaded column 133 rotates synchronously, and the rotation of the threaded column 133 drives the push rod 132 to move in the direction of the gear. During this process, the adjusting gear 134 always keeps in meshing state with the tooth plate 135. As the push rod 132 moves, the push rod 132 pushes the connecting rod 131 to move outward through the truncated cone section, and the connecting rod 131 pushes the auxiliary push rod 130 to rotate around the hinge point between it and the outer push rod 125 until the auxiliary push rod 130 and the outer push rod 125 are synchronously pressed against the tooth groove of the gear. The auxiliary push rod 130 can be used to assist the outer push rod 125 to press and fix the gear tooth groove at multiple points, thereby increasing the pressing force on the gear in the circumferential direction and further improving the stability of the gear.

[0043] See also Figure 1 , Figure 2 , Figure 7 , Fig.10 and Fig.11 A drilling assembly 14 is arranged above the processing truncated table 1, and the drilling assembly 14 includes a movable plate 140. Vertical guide rails 141 are installed on the upper ends of the left and right fixed brackets. A movable plate 140 that slides up and down is connected between the left and right vertical guide rails 141. An electric slider that is fixedly connected to the upper end surface of the movable plate 140 is slidably installed on the vertical guide rail 141. An automatic drilling machine 143 is arranged at the lower end of the movable plate 140. A left-right symmetrical drill bit is arranged at the lower end of the automatic drilling machine 143. A positioning column 144 located between the left and right drill bits and plugged with the upper end of the positioning rod 114 is installed at the lower end of the automatic drilling machine 143. The front and rear ends of the movable plate 140 slide up and down. A spring rod 145 is dynamically installed, a pressure ring 146 is connected between the lower ends of the front and rear spring rods 145, a front and rear symmetrical pressure rod 147 is installed on the outer ring surface of the pressure ring 146, a left and right symmetrical pressure block 152 is arranged below the pressure ring 146, a spring telescopic rod 148 is connected between the pressure block 152 and the pressure ring 146, a funnel-shaped frame 149 is provided on the outside of the automatic drilling machine 143 for upward and downward sliding, a magnet plate 150 is arranged inside the funnel-shaped frame 149, support rods 151 that slide up and down and penetrate the movable plate 140 are installed on the upper ends of the left and right sides and the front and rear sides of the funnel-shaped frame 149, and a blocking plate is installed in a detachable manner after the support rod 151 penetrates the movable plate 140.

[0044] During operation: after the pressing plate 115 is placed on the upper end of the gear, the movable plate 140 can be driven by the electric slider to move downward along the vertical guide rail 141, and the movable plate 140 drives the automatic drilling machine 143 to move downward synchronously. During this process, the spring rod 145 first drives the pressing ring 146 and the pressing rod 147 to move downward until they contact the pressing plate 115. The spring rod 145 subjected to resistance can move upward relative to the movable plate 140 by compressing the spring. At this time, the pressing ring 146 is located in the arc arranged inside and outside. The inner and outer arc plates 119 and the vertical through grooves can be used to guide the pressing ring 146 and the pressing rod 147 during the pressing process. As the movable plate 140 continues to move downward, the pressing ring 146 and the pressing rod 147 can press the pressing plate 115 and the lever 118 respectively, exerting downward pressure on the pressing plate 115 and the lever 118, and firmly fixing the pressing plate 115 on the upper end of the gear, further improving the The stability between the high-pressure plate 115 and the fixing ring 123 increases the stability between the adjusting rod 120 and the socket 153, thereby ensuring the stability of the gear in the up and down directions. Before the pressing plate 115 presses the gear, the pressing plate 115 can drive the adjusting rod 120 to move downward in advance and implement the above-mentioned operation of correcting the gear position. Before the pressing ring 146 contacts the pressing plate 115, the pressing ring 146 can drive the spring telescopic rod 148 and the pressing block 152 to move downward synchronously until they are in direct contact with the upper end surface of the gear, and directly apply downward pressure to the gear through the pressing block 152 to further stabilize the position of the gear. The pressing ring 146 and the pressing block 152 can not only realize the fixation of the internal fixing component 11, but also perform multi-directional pressing and fixing on the upper end of the gear, effectively preventing the gear from shaking up and down during the drilling process, thereby improving the drilling processing quality and processing accuracy. After completing the fixation of the upper end of the gear, the above-mentioned external fixing component 12 can be implemented to perform circumferential fixing of the gear.

[0045] In the process of applying pressure to the upper end of the gear, the automatic drilling machine 143 gradually reaches the upper end of the gear, and the drill bits on both sides reach the appropriate drilling position. After the gear is completely fixed, the automatic drilling machine 143 continues to move downward, and the spring on the spring rod 145 and the spring telescopic rod 148 shrink synchronously. At the same time, the automatic drilling machine 143 can control the left and right drill bits to rotate synchronously and quickly. After the drill bits move to pass through the circular through hole 154, the drilling operation of the left and right processing holes of the gear can be completed at the same time (the gear after the drilling is completed is as follows Fig.11As shown in the figure, during this process, the automatic drilling machine 143 can be plugged and matched with the upper end of the positioning rod 114 through the alignment column 144 at its lower end. Through the cooperation between the alignment column 144 and the positioning rod 114, the stability of the automatic drilling machine 143 when moving down for drilling can be effectively increased, thereby improving the quality and accuracy of the drilling process, and further improving the drilling process efficiency. In addition, during the downward movement of the automatic drilling machine 143, the funnel-shaped frame 149 is synchronously moved downward through the support rod 151. When the drill bit reaches a suitable drilling position, the funnel-shaped frame 149 and the pressure plate 115 The support rod 151 is driven to move upward along the automatic drilling machine 143 due to the friction. During the drilling process, the funnel-shaped frame 149 can cover the drill bit when it is working. At the same time, the debris generated during drilling can be adsorbed and collected by the magnet plate 150 to prevent the debris from splashing around during drilling and affecting the subsequent fixing and drilling of gears. At the same time, the pollution to the working environment is reduced and the time for subsequent separate cleaning of the debris is shortened.
