Description

Technical Field

[0001] This application relates to the field of mechanical assembly technology, and in particular to a linkage assembly device. Background Technology

[0002] A drain cleaner, commonly known as a "drain cleaning machine" or "pipe cleaner," is a tool used to remove debris clogging pipes. Drain cleaners typically feature a linkage assembly, see [reference needed]. Figure 1 and Figure 2 The connecting rod assembly 1 includes a connecting rod conduit 11, a plastic sleeve 12 connected to one end of the connecting rod conduit 11, a connecting rod shaft 13 disposed within the plastic sleeve 12, and a spring pin 14. The plastic sleeve 12 has an installation through hole 121 for arranging the connecting rod shaft 13 and a first through hole 122 is formed on the inner wall of the installation through hole 121. The connecting rod conduit 11 has a second through hole 111 corresponding to the first through hole 122, and the connecting rod shaft 13 has a third through hole 131 corresponding to the first through hole 122.

[0003] When assembling the connecting rod assembly 1, the operator first fits the connecting rod tube 11 onto the plastic sleeve 12, aligns the second through hole 111 with the first through hole 122, then places the connecting rod shaft 13 into the mounting through hole 121 of the plastic sleeve 12, and aligns the third through hole 131 with the first through hole 122. At this time, the three through holes are coaxial. Finally, the spring pin 14 is inserted into the three through holes to fix the connecting rod tube 11, the plastic sleeve 12, and the connecting rod shaft 13.

[0004] During assembly, the connecting rod tube 11 and connecting rod shaft 13 are prone to relative rotation with the plastic sleeve 12, causing the second through hole 111 and the third through hole 131 to misalign with the first through hole, making it impossible to effectively insert the spring pin 14. At this time, the operator needs to precisely adjust the angle of the connecting rod tube 11 and the connecting rod shaft 13 to insert the spring pin 14 and complete the assembly. However, this operation not only increases the labor intensity but also reduces the assembly efficiency. Utility Model Content

[0005] In order to reduce the labor intensity of operators assembling the linkage assembly of the pipe cleaner and improve the assembly efficiency, this application provides a linkage assembly device.

[0006] The connecting rod assembly device provided in this application adopts the following technical solution: A connecting rod assembly device includes a positioning mechanism for positioning the connecting rod assembly, a feeding mechanism for feeding a spring pin, and a pushing mechanism for pushing the spring pin. The positioning mechanism includes a first support seat for arranging the connecting rod pipe, a positioning block disposed on the first support seat for arranging the plastic sleeve, a second support seat for arranging the connecting rod shaft, a first positioning component for positioning the connecting rod pipe and the plastic sleeve, a second positioning component for positioning the connecting rod shaft, and a first driving member disposed on the second positioning component for pushing the connecting rod shaft to move horizontally.

[0007] By adopting the above technical solution, the connecting rod tube, plastic sleeve, and connecting rod shaft of the connecting rod assembly can be respectively arranged on the first support seat, positioning block, and second support seat of the positioning mechanism. Simultaneously, the first positioning component positions the connecting rod tube and plastic sleeve, and the second positioning component positions the connecting rod shaft. Then, driven by the first driving component, the connecting rod shaft is pushed into the mounting through hole of the plastic sleeve, aligning the third through hole of the connecting rod shaft with the first through hole of the plastic sleeve. Finally, the pushing mechanism pushes the spring pin to insert and fix the connecting rod tube, plastic sleeve, and connecting rod shaft. This avoids relative rotation between the connecting rod tube and connecting rod shaft and the plastic sleeve, preventing misalignment of the through holes, thereby helping to reduce manual labor intensity and improve assembly efficiency.

[0008] Optionally, the first positioning component includes a first positioning cylinder disposed on the first support base and a first positioning pin connected to the output end of the first positioning cylinder, and the first support base has a first positioning through hole through which the first positioning pin passes; the second positioning component includes a second positioning cylinder disposed on the second support base and a second positioning pin connected to the output end of the second positioning cylinder, and the second support base has a second positioning through hole through which the second positioning pin passes.

[0009] By adopting the above technical solution, the specific structures of the first positioning component and the second positioning component are disclosed. The first positioning pin of the first positioning component can move under the drive of the first positioning cylinder and insert into the first through hole and the second through hole, so that the operator can accurately place the connecting rod pipe with the plastic sleeve on the first support seat. The second positioning pin of the second positioning component can move under the drive of the second positioning cylinder and insert into the third through hole, so that the operator can accurately place the connecting rod shaft on the second support seat, which helps the subsequent assembly operation to proceed smoothly.

[0010] Optionally, the positioning block has a first positioning groove for arranging the end of the plastic sleeve, and an abutment post is provided on the first positioning groove to engage with the plastic sleeve.

[0011] By adopting the above technical solution, the positioning block has a first positioning groove and an abutment post that engages with the plastic sleeve in the first positioning groove, which helps to better position the plastic sleeve and prevent the plastic sleeve from rotating during assembly.

[0012] Optionally, the second support base has a second positioning groove for arranging the connecting rod shaft and a clearance groove communicating with the second positioning groove.

[0013] By adopting the above technical solution, the second support seat is provided with a clearance groove that connects to the second positioning groove, which makes it convenient for the operator to arrange the connecting rod shaft on the second support seat.

[0014] Optionally, the feeding mechanism includes a feeding platform, a hopper seat installed on the feeding platform, a feeding hopper disposed on the hopper seat, a feeding plate located below the feeding hopper, and a second driving member for driving the feeding plate to move horizontally. The feeding platform has a feeding through hole for the feeding plate to pass through, the feeding hopper has a feeding through hole for a single spring pin to pass through sequentially, and the feeding plate has a receiving through hole corresponding to the feeding through hole and for a single spring pin to be arranged.

[0015] By adopting the above technical solution, the specific structure of the feeding mechanism is disclosed. The feeding mechanism includes a feeding platform, a hopper seat, a feeding hopper, a feeding plate, and a second driving component. The spring pin can sequentially move downward along the feeding through hole of the feeding hopper and enter the receiving through hole of the feeding plate. Then, the second driving component pushes the feeding plate to move horizontally, so that the spring pin reaches the feeding position.

[0016] Optionally, the pushing mechanism includes a punch seat located on the loading platform and a third driving component for driving the punch seat to rise and fall. The punch seat is provided with a clamping rod for pushing the spring pin, and the loading platform has a pushing through hole in the inner wall of the feeding through hole for the clamping rod to pass through.

[0017] By adopting the above technical solution, the specific structure of the pushing mechanism is disclosed. The pushing mechanism includes a punch seat and a third driving component that drives the punch seat to rise and fall. The clamping rod of the punch seat can pass through the pushing through hole of the loading table, which can smoothly push the spring pin delivered to the loading mechanism, thereby realizing the installation of the spring pin and helping to improve assembly efficiency.

[0018] Optionally, the clamping rod includes a first column, a second column located below the first column, a third column located below the second column, a first pedestal connecting the first column and the second column, and a second pedestal connecting the second column and the third column. The loading platform has a first arrangement groove for the first pedestal to abut against and a second arrangement groove for the second pedestal to abut against. The outer diameter of the first column is larger than the outer diameter of the second column, and the outer diameter of the second column is larger than the outer diameter of the third column.

[0019] By adopting the above technical solution, the first and second pillars of the clamping rod abut against the first and second arrangement slots of the loading platform, respectively. At the same time, the outer diameter of the first pillar is larger than the outer diameter of the second pillar, and the outer diameter of the second pillar is larger than the outer diameter of the third pillar. This can limit the descent position of the clamping rod, ensure that the clamping rod accurately inserts the spring pin into the through hole of the connecting rod assembly, and also help reduce the probability of deviation or shaking during the pushing process.

[0020] Optionally, the feeding mechanism further includes a fixed frame, a guide rail disposed on the fixed frame, a guide slider disposed on the loading platform and cooperating with the guide rail, and a fourth driving component for driving the loading platform to rise and fall.

[0021] By adopting the above technical solution, the fixed frame, guide rail, guide slider and fourth drive component of the feeding mechanism work together to enable the loading platform to rise and fall smoothly. After the operator arranges the connecting rod pipe, plastic sleeve and connecting rod shaft, the loading platform descends and approaches the connecting rod pipe under the drive of the fourth drive component, which facilitates the accurate pushing of the spring pin into the through hole of the connecting rod assembly, and helps to improve the spring pin pushing accuracy and assembly stability.

[0022] In summary, this application includes at least one of the following beneficial technical effects: A connecting rod assembly device includes a positioning mechanism, a feeding mechanism, and a pushing mechanism. The positioning mechanism includes a first support base, a positioning block, a second support base, a first positioning component, a second positioning component, and a first driving component. The first positioning component can position the connecting rod tube and the plastic sleeve, and the second positioning component can position the connecting rod shaft. This helps to reduce manual labor intensity and improve assembly efficiency. By setting a first positioning pin in the first positioning component and a second positioning pin in the second positioning component, the operator can accurately place the connecting rod pipe with the plastic sleeve onto the first support seat and accurately place the connecting rod shaft onto the second support seat.

[0023] By providing a first positioning groove on the positioning block and setting an abutment post on the first positioning groove that engages with the plastic sleeve, the positioning block can better position the plastic sleeve and prevent the plastic sleeve from rotating during assembly, thus affecting the assembly of the spring pin.

The first positioning pin 352 can rise and fall under the drive of the first positioning cylinder 351. The first positioning pin 352 can be simultaneously inserted into the first through hole 122 of the plastic sleeve 12 and the second through hole 111 of the connecting rod tube 11, thereby completing the positioning of the plastic sleeve 12 and the connecting rod tube 11. The second positioning component 36 includes a second positioning cylinder 361 disposed on a second support base 33 and a second positioning pin 362 connected to the output end of the second positioning cylinder 361. The second support base 33 has a second positioning through hole 333 through which the second positioning pin 362 passes. The second positioning pin 362 can be raised and lowered under the drive of the second positioning cylinder 361. The second positioning pin 362 can be inserted into the third through hole 131 of the connecting rod shaft 13 to complete the positioning of the connecting rod shaft 13.

[0036] Reference Figure 5The positioning block 32 has a first positioning groove 321 for the end of the plastic sleeve 12 to be arranged, and an abutment post 322 for inserting and engaging with the plastic sleeve 12 is provided on the first positioning groove 321, which can effectively prevent the plastic sleeve 12 from rotating during assembly. The second support base 33 has a second positioning groove 331 for the connecting rod shaft 13 to be arranged, and a clearance groove 332 communicating with the second positioning groove 331, which makes it convenient for the operator to arrange the connecting rod shaft 13 on the second support base 33.

[0037] Reference Figure 6 The feeding mechanism 4 includes a fixed frame 41 mounted on a fixed base plate 22, a fourth driving member 42 mounted on the fixed base plate 22, a connecting plate 43 connected to the output end of the fourth driving member 42, a third driving member 44 mounted on a mounting top plate 23, and a punch seat 45 connected to the output end of the third driving member 44. The punch seat 45 is provided with a clamping rod 451 that passes vertically through the connecting plate 43. In this embodiment, both the third driving member 44 and the fourth driving member 42 are cylinders. The third driving member 44 can drive the punch seat 45 to rise and fall, and the fourth driving member 42 can drive the connecting plate 43 to rise and fall.

[0038] Reference Figure 1 and Figure 6 The feeding mechanism 5 includes a feeding platform 51 fixedly connected to the bottom of the connecting plate 43, a hopper seat 52 installed on the side wall of the feeding platform 51, a feeding hopper 53 disposed on the hopper seat 52, a feeding plate 54 located below the feeding hopper 53, and a second driving member 55 for driving the feeding plate 54 to move horizontally. The pushing assembly also includes a guide rail 46 disposed on the fixed frame 41, a guide slider 47 disposed on the feeding platform 51 and cooperating with the guide rail 46, and a fourth driving member 42 capable of driving the connecting plate 43 to drive the feeding platform 51 to rise and fall stably, so that the feeding platform 51 is close to the connecting rod pipe 11 for subsequent assembly.

[0039] Reference Figure 7 The loading platform 51 has a feeding through hole 511 through which the feeding plate 54 passes. The inner wall of the feeding through hole 511 has a pushing through hole 512 through which the clamping rod 451 passes. The loading bin 53 has a loading through hole 531 through which a single spring pin passes sequentially. The feeding plate 54 has a receiving through hole 541 corresponding to the loading through hole 531 and for arranging a single spring pin. In this embodiment, the loading bin 53 is made of transparent plastic, allowing the operator to observe the remaining spring pins in the loading bin 53 and replenish them promptly when necessary. In this embodiment, the second driving component 55 is a cylinder. When a spring pin is arranged in the receiving through hole 541 of the feeding plate 54, the second driving component 55 pushes the feeding plate 54 to move, causing the receiving through hole 541 to coaxially connect with the pushing through hole 512. At this time, the spring pin is located directly below the clamping rod 451.

[0040] Reference Figure 7 The clamping rod 451 includes a first column 4511, a second column 4512 located below the first column 4511, a third column 4513 located below the second column 4512, a first support 4514 connecting the first column 4511 and the second column 4512, and a second support 4515 connecting the second column 4512 and the third column 4513. The loading table 51 has a first arrangement groove 513 for the first support 4514 to abut against and a second arrangement groove 514 for the second support 4515 to abut against. The outer diameter of the first column 4511 is larger than the outer diameter of the second column 4512, and the outer diameter of the second column 4512 is larger than the outer diameter of the third column 4513. When the first post 4514 of the clamping rod 451 abuts against the first arrangement groove 513, the second post 4515 abuts against the second arrangement groove 514. At this time, the spring pin is pressed into the connecting rod pipe 11, plastic sleeve 12 and connecting rod shaft 13 by the clamping rod 451, thus completing the assembly of the connecting rod assembly 1.

[0041] The implementation principle of a connecting rod assembly device according to an embodiment of this application is as follows: The operator arranges the pre-assembled connecting rod pipe 11 and plastic sleeve 12 on the first support base 31 and positioning block 32, and arranges the connecting rod shaft 13 on the second support base 33. At this time, the first positioning pin 352 of the first positioning component 35 is inserted into the first through hole 122 of the plastic sleeve 12 and the second through hole 111 of the connecting rod pipe 11, and the second positioning pin 362 of the second positioning component 36 is inserted into the third through hole 131 of the connecting rod shaft 13. Then, the second positioning cylinder 361 drives the second positioning pin 362 to descend, and the first driving component 34 pushes the connecting rod shaft 13 into the mounting through hole 121 of the plastic sleeve 12. At this time, the third through hole 131 of the connecting rod shaft 13 is aligned with the first through hole 122 of the plastic sleeve 12. Then, the clamping rod 451 of the pushing mechanism 4 presses the spring pin into the connecting rod pipe 11, the plastic sleeve 12 and the connecting rod shaft 13, fixing the connecting rod pipe 11, the plastic sleeve 12 and the connecting rod shaft 13, thereby completing the assembly of the connecting rod assembly 1, which effectively reduces the labor intensity of the operators and improves the assembly efficiency.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
