Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a bushing flanging stamping equipment. Background Technology

[0002] In the field of mechanical manufacturing, the pressing and flanging of bushings are key processes affecting the connection strength and dimensional accuracy of products. In traditional processes, the pressing, pre-flanging, and precision stamping of bushings are usually completed in multiple independent workstations. This requires manual or semi-automated equipment to perform multiple positioning, transfer, and processing operations on the workpiece. The workpiece needs to be transferred and positioned multiple times between multiple machines, resulting in a lengthy processing flow and difficulty in coordinating the cycle times between different processes, which seriously restricts production efficiency. At the same time, in the traditional pre-flanging process, the control of the initial flanging angle of the bushing depends on manual operation experience, and the 90° bend in the subsequent stamping is prone to cracking or springback due to uneven stamping pressure, resulting in a low yield rate of the final product and high production costs.

[0046] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0047] like Figure 1 As shown, this application proposes a bushing flanging and stamping equipment, which includes a machine base with a feeding module 1, a pre-flanging module 2, a stamping module 3, a blanking module 4, and a transfer module 5 for transferring workpieces between the above modules, arranged sequentially along the processing flow. Through the coordinated actions of the modules, automated feeding and assembly of the lead screw and bushing are achieved, effectively improving work efficiency and assembly accuracy between the lead screw and bushing.

[0048] like Figure 1 As shown, the feeding module 1 includes a workpiece feeding mechanism 11 and a bushing feeding mechanism 12. The workpiece feeding mechanism 11 and the bushing feeding mechanism 12 are respectively arranged on one side of the pre-flanging module 2 to realize the automated feeding of workpieces and bushings.

[0049] like Figure 1-3 As shown, the workpiece loading mechanism 11 includes a feeding component 111 and a transfer execution component 112. The feeding component 111 is used to carry the workpiece, and the transfer execution component 112 is used to separate the workpiece on the feeding component 111.

[0050] like Figure 1-3 As shown, the feeding component 111 includes two sets of guide side plates 1111 arranged in parallel to each other, forming a workpiece conveying channel between them. A support platform 1112 is horizontally arranged on the inner side of the guide side plate 1111. Positioning grooves 1113 are arranged equidistantly along the axial direction on the surface of the support platform 1112 for supporting both ends of the workpiece.

[0051] like Figure 1-3 As shown, the material transfer execution component 112 is disposed between the workpiece conveying channels. It includes a material transfer base plate 1121, a first lifting drive unit 1122, and a first linear guide module 1123. The material transfer base plate 1121 is disposed below the support platform 1112. The first lifting drive unit 1122 is connected to the material transfer base plate 1121 to drive the material transfer base plate 1121 to move vertically. The first linear guide module 1123 is coupled to the first lifting drive unit 1122 and is configured to drive the first lifting drive unit 1122 to translate axially along the conveying channel. The surface of the material transfer base plate 1121 is provided with axially equidistant material transfer slots 1124, the adjacent spacing of which matches the spacing of adjacent positioning grooves 1113. During the lifting process, the material transfers the workpiece away from the support platform 1112.

[0052] Workpieces are manually placed sequentially along the axial direction into the positioning grooves 1113 of the support platform 1112. The first lifting drive unit 1122 drives the transfer plate 1121 to rise, and the transfer bayonet 1124 lifts the workpiece and removes it from the support platform 1112. The first linear guide module 1123 drives the first lifting drive unit 1122 to move axially, moving the workpiece in the set of transfer bayonet 1124 at the axial end to outside the conveying channel for subsequent removal. Then, the first lifting drive unit 1122 drives the transfer plate 1121 to descend below the support platform 1112, and the workpiece continues to fall back into the positioning grooves 1113. The first linear guide module 1123 continues to drive the first lifting drive unit 1122 to retract along the axial direction to its original position, thus repeatedly separating and removing the workpiece at the axial end for easy gripping. Preferably, the translational distance of the first linear guide module 1123 driving the first lifting drive unit 1122 is equal to the distance between two adjacent positioning grooves 1113, so that a single workpiece can be separated each time.

[0053] like Figure 1-4 As shown in this exemplary embodiment, the workpiece feeding mechanism 11 further includes a temporary storage component 113 and a transfer component 114. The temporary storage component 113 is disposed on the horizontal side of the pre-flanging module 2, and the feeding component 111 is disposed on the opposite side of the pre-flanging module 2. The transfer component 114 is used to transfer the workpiece separated by the transfer execution component 112 to the temporary storage component 113. By adjusting the layout of the above components, the space utilization rate is effectively improved and the overall volume of the equipment is reduced.

[0054] like Figure 1-4 As shown, the temporary storage component 113 includes a temporary storage positioning platform 1131 and a second linear guide module 1132. The surface of the temporary storage positioning platform 1131 is provided with a temporary storage groove 1133 that matches the contour of the workpiece. The second linear guide module 1132 is configured to drive the temporary storage positioning platform 1131 to translate between the feeding station and the receiving station. The feeding station is configured to be close to the material distribution end of the transfer execution component 112, and the receiving station is configured to be close to the pre-flanging module 2. The temporary storage positioning platform 1131 receives the workpiece at the feeding station, and the second linear guide module 1132 drives the temporary storage positioning platform 1131 to move laterally to the receiving station, so that the transfer module can transfer the workpiece to the pre-flanging module 2. Preferably, the temporary storage component 113 further includes a second lifting drive unit 1134 connected to the temporary storage positioning stage 1131. The second lifting drive unit 1134 is coupled to the second linear guide rail module 1132. The second linear guide rail module 1132 drives the second lifting drive unit 1134 to move horizontally, and the second lifting drive unit 1134 drives the temporary storage positioning stage 1131 to rise and fall vertically. The receiving height of the temporary storage positioning stage 1131 can be adjusted to ensure accurate receiving and feeding of materials.

[0055] like Figure 1-4As shown, the transfer component 114 includes a first pneumatic gripper 1141 for clamping the workpiece, a third lifting drive unit 1142 for driving the first pneumatic gripper 1141 to move up and down, and a third linear guide module 1143 for driving the third lifting drive unit 1142 to move laterally.

[0056] like Figure 5-7 As shown, the bushing feeding mechanism 12 includes a vibratory plate 121, a straight material channel 122 connected to the discharge end of the vibratory plate 121, a material distribution component 123 connected to the discharge end of the straight material channel 122, and a transfer component 124 that transfers the bushing from the material distribution component 123 to the pre-flanging execution component. The bottom of the straight material channel 122 is connected to a matching straight vibrator.

[0057] like Figure 5-6 As shown, the above-mentioned material distribution component 123 includes a material distribution bracket 1231. The material distribution bracket 1231 has a material distribution groove 1232 with an opening on one side. The material distribution groove 1232 is connected to the straight material channel 122. The material distribution groove 1232 can accommodate a single bushing. A material blocking unit is provided at the opening of the material distribution groove 1232 to block the continuous material supply from the straight material channel 122. An angle adjustment unit is provided at the lower end of the material distribution bracket 1231 to adjust the angle of the separating bushing so that the notch position of the bushing meets the installation requirements.

[0058] like Figure 5-6 As shown, the material blocking unit includes a material blocking rod 1238 and a material blocking drive cylinder 1239 that drives the material blocking rod 1238 to insert into the opening of the material receiving groove 1232. A sensor is provided on one side of the material receiving groove 1232. Once the sensor detects that a bushing has entered the material receiving groove 1232, the material blocking drive cylinder 1239 drives the material blocking rod 1238 to extend to the opening of the material receiving groove 1232, separating the material receiving groove 1232 from the straight material channel 122, and preventing the bushing in the straight material channel 122 from continuing to enter the material receiving groove 1232, thereby realizing the material distribution of a single bushing.

[0059] like Figure 5-6As shown, the angle adjustment unit includes a linkage plate (not shown) and a fourth lifting drive unit 1233 that drives the linkage plate to rise and fall. A first rotary cylinder 1234 and a sensor 1237 are spaced apart on the linkage plate. The output end of the first rotary cylinder 1234 faces upward and is connected to a top material rod 1235. The upper end of the top material rod 1235 passes through the material distribution bracket 1231. A positioning protrusion 1236 is provided at the center of the upper end of the top material rod 1235. The positioning protrusion 1236 can be inserted into the center hole of the bushing. The upper end face of the top material rod 1235 supports the lower end of the bushing. The first rotary cylinder 1234 drives the top material rod 1235 to rotate, which in turn drives the bushing to rotate synchronously. The fourth lifting drive unit 1233 drives the connecting plate to move upward, so that the bushing at the upper end of the top material rod 1235 and the sensor 1237 move upward synchronously until the bushing moves above the material receiving groove 1232, so that the sensor 1237 can detect the bushing. The first rotary cylinder 1234 drives the top material rod 1235 to rotate. When the sensor 1237 detects the bushing notch, the first rotary cylinder 1234 stops rotating.

[0060] like Figure 7 As shown in this exemplary embodiment, the transfer member 124 includes a second pneumatic gripper 1241 for holding the bushing, a fourth linear guide module 1242 for driving the second pneumatic gripper 1241 to move horizontally, and a fifth lifting drive unit 1243 for driving the second pneumatic gripper 1241 to move vertically. The second pneumatic gripper 1241 is used to grip the bushing after angle adjustment and transfer it to the bushing gripping unit of the pre-flanging module 2.

[0061] like Figure 1 , 8 As shown in Figure 10, the pre-flanging module 2 includes a first carrier 21 and a pre-flanging actuator 22. The first carrier 21 is used to position the workpiece to be processed. The pre-flanging actuator 22 is located directly above the first carrier 21 and is configured to press the bushing into the workpiece assembly hole and form an initial flanging at the lower end of the bushing. The stamping module 3 includes a second carrier 31 and a precision stamping mechanism 32. The second carrier 31 is used to receive the pre-flanged workpiece. The precision stamping mechanism 32 is located directly above the second carrier 31 and is configured to apply axial stamping force to the bushing to form a 90° bend in the initial flanging, thus completing the flanging press-fit between the bushing and the workpiece.

[0062] like Figure 9 and 11As shown, both the first carrier 21 and the second carrier 31 include a positioning component 211. The positioning component 211 includes a contoured end baffle 2111 and a reference end baffle 2112 arranged opposite to each other. The center of the contoured end baffle 2111 is provided with a limiting groove 2113 that is adapted to the contour of the end of the workpiece. The bottom of the limiting groove 2113 has a bearing base surface. The bearing base surface is used to support the end face of the workpiece with the assembly hole. The two ends of the workpiece are respectively restricted between the contoured end baffle 2111 and the reference end baffle 2112.

[0063] like Figure 9 As shown, a positioning column 212 is vertically protruding on the bearing base surface of the first carrier 21. The positioning column 212 forms a clearance fit with the workpiece assembly hole. An annular limiting groove 213 is opened in the circumferential direction of the positioning column 212. The bottom of the groove of the positioning column 212 and the annular limiting groove 213 are connected by an arc-shaped transition part. The annular transition part and the annular limiting groove 213 form a radial guiding channel to guide the lower end of the bushing to generate an initial bending angle in the pre-flanging process.

[0064] like Figure 10 As shown, a precision positioning column 311 is vertically protruding on the bearing base surface of the second carrier 31. The precision positioning column 311 forms a clearance fit with the workpiece assembly hole. An annular reference groove 312 is opened in the circumferential direction of the precision positioning column 311. The precision positioning column 311 and the annular reference groove 312 are connected by a 90° vertical transition structure. In the precision stamping process, it abuts against the lower end of the bushing to make it pre-flanged and compacted to form a 90° bend.

[0065] like Figure 8-9 As shown, the pre-flanging actuator 22 includes a first support frame 221, a first mounting plate 222 movably connected to the first support frame 221, and a first lifting cylinder 223 that drives the first mounting plate 222 to rise and fall vertically. A bushing clamping unit is configured on the first mounting plate 222 to drive the bushing to rise and fall synchronously. Preferably, in this embodiment, the bushing clamping unit is configured as a magnetic suction head 224 located on the lower end face of the first mounting plate 222 for magnetically adsorbing the bushing. Specifically, the lower end face of the magnetic suction head 224 has a downwardly protruding boss 2241. The boss 2241 is coaxially arranged with the positioning column 212 of the first carrier 21 to position the center hole of the bushing, thereby precisely limiting the magnetic suction position of the bushing, ensuring accurate pressing position of the bushing, and improving the pressing accuracy of the bushing. The first lifting cylinder 223 drives the first mounting plate 222 to move downward, and the magnetic suction head 224 drives the bushing to press downward into the workpiece assembly hole in sync. The lower end of the bushing moves downward from the gap between the workpiece assembly hole and the positioning column, and realizes the folding action along the arc transition part.

[0066] like Figure 10-11As shown, the precision stamping mechanism 32 includes a second support frame 321, a second mounting plate 322 movably connected to the second support frame 321, and a second lifting cylinder 323 that drives the second mounting plate 322 to rise and fall. A precision stamping head 324 is disposed on the lower end face of the second mounting plate 322 for pressing the bushing downward. The lower end face of the precision stamping head 324 has a clearance hole coaxially arranged with the precision positioning column 311. The second lifting cylinder 323 drives the second mounting plate 322 to move downward, the precision positioning column 311 is inserted into the clearance hole, and the precision stamping head 324 presses the bushing downward, so that the lower end pre-flanged portion of the bushing forms a 90° angle along the vertical transition structure, thereby completing the flanging assembly of the bushing and the workpiece.

[0067] like Figure 12 As shown, the unloading module 4 is equipped with a finished product receiving carrier 41 for receiving the assembled parts that have completed the stamping process. The upper surface of the finished product receiving carrier 41 has a receiving groove 411 that is adapted to the workpiece for placing the workpiece.

[0068] like Figure 12 As shown, in this embodiment, the unloading module 4 has two sets of finished product receiving carriers 41 and an alternating movement mechanism. The finished product receiving carriers 41 are used to receive finished workpieces at the receiving station and transfer the finished workpieces to the unloading station for unloading. The alternating movement mechanism is used to drive the two sets of finished product receiving carriers 41 to move alternately between the receiving station and the unloading station. By using the two sets of finished product receiving carriers 41 to receive and unload in sequence, the work efficiency is effectively improved and the work cycle is accelerated.
