Abstract
Description
Technical Field
[0001] This application relates to the technical field of drilling equipment, and in particular to a mounting structure for a pressure foot cup. Background Technology
[0002] Pressure foot cups, also known as pressure feet, are components used in the PCB drilling process. During the drilling operation on a PCB board, pressure foot cups serve to press the PCB board and position the drilling hole, playing an important role in high-precision drilling operations.
[0003] The pressure foot cup needs to be horizontally fixed on a mounting base during use to improve the stability of drilling operations. Currently, the pressure foot cup is usually horizontally fixed to the mounting base by tightening bolts. This bolting method is cumbersome, makes disassembly and assembly of the pressure foot cup inconvenient, and after repeated tightening, the pressure foot cup is prone to loosening on the mounting base, thus reducing the stability of drilling operations and consequently reducing drilling accuracy. This problem urgently needs to be improved. Utility Model Content
[0004] To facilitate the installation of the pressure foot cup and improve the stability and accuracy of drilling operations, this application provides an installation structure for the pressure foot cup.
[0005] The mounting structure for a pressure foot cup provided in this application adopts the following technical solution:
[0006] A mounting structure for a presser foot cup includes a presser foot cup and a mounting base, and further includes a quick-release mechanism for quickly assembling and disassembling the presser foot cup and the mounting base. The quick-release mechanism includes a positioning component, a snap-fit component, and a control system. The positioning component is disposed between the presser foot cup and the mounting base to connect the presser foot cup to the mounting base in a horizontal state. The snap-fit component is disposed on the positioning component to fix the presser foot cup to the mounting base. The control system is connected to the mounting base to control the opening and closing of the snap-fit component.
[0007] By adopting the above technical solution, the quick-release mechanism enables rapid disassembly and assembly of the pressure foot cup and the mounting base, which helps to improve the disassembly and assembly speed. When the pressure foot cup needs to be installed on the mounting base, the control system first controls the snap-fit component to open so that the positioning component can connect the pressure foot cup to the mounting base in a horizontal state. Then, the control system controls the snap-fit component to close so that the pressure foot cup is fixed on the mounting base. This is convenient and quick, and the snap-fit method of fixing the connection will not cause wear. It is difficult for the pressure foot cup and the mounting base to loosen, which helps to improve the stability and accuracy of drilling operations.
[0008] Preferably, the positioning component includes two positioning posts, which are vertically fixed to both sides of the lower surface of the mounting base. The pressure foot cup has positioning grooves on opposite sides for the positioning posts to be inserted into, and the positions of the two positioning grooves correspond to the positions of the two positioning posts.
[0009] By adopting the above technical solution, the two positioning pins on the lower surface of the mounting base are respectively inserted into the two positioning slots on the pressure foot cup, so as to realize the positioning of the pressure foot cup and the mounting base during the installation process, which is conducive to improving the stability of the subsequent snap-fit process.
[0010] Preferably, the snap-fit assembly includes a plurality of snap-fit beads, the positioning post is hollow, and the side wall of the positioning post is provided with a plurality of through holes for the snap-fit beads to protrude out. The control system is used to control whether the snap-fit beads protrude out of the through holes, and the groove wall of the positioning groove is provided with a corresponding snap-fit groove for the snap-fit beads to snap into.
[0011] By adopting the above technical solution, when the positioning pin is inserted into the positioning groove, the retaining ball protrudes from the through hole and is locked into the groove, so as to realize the snap-locked connection of the pressure foot cup on the mounting base, which has strong stability and is not prone to wear.
[0012] Preferably, the control system includes a pushing component and a driving component. The pushing component is movably disposed inside the positioning post for pushing the retaining bead, and the driving component is connected to the positioning post for driving the pushing component to move vertically up and down.
[0013] By adopting the above technical solution, when it is necessary to insert the positioning post into the positioning groove or remove the pressure foot cup from the mounting base, the drive component drives the pusher to move vertically upward so that the retaining ball enters the positioning post. When it is necessary to lock the pressure foot cup and the mounting base together, the drive component drives the pusher to move vertically downward. The pusher pushes the retaining ball to move so that the retaining ball protrudes through the through hole and is locked into the slot.
[0014] Preferably, the pushing member is configured as a piston column, the bottom of the piston column is configured in the shape of an inverted frustum, and the bottom sidewall of the piston column abuts against the retaining ball.
[0015] By adopting the above technical solution, when the drive assembly drives the piston rod to move vertically downward, the bottom side wall of the piston rod presses against the retaining ball, so that the retaining ball protrudes through the through hole. When the drive assembly drives the piston rod to move vertically upward, the piston rod releases the pressure on the retaining ball, and the retaining ball can enter the entire interior of the positioning rod.
[0016] Preferably, the driving component includes a vacuum suction system and an elastic element, the top of the elastic element being fixedly connected to the top of the internal space of the positioning column, the bottom of the elastic element being fixedly connected to the top of the pushing element, and the vacuum suction system being connected to the internal space of the positioning column.
[0017] By adopting the above technical solution, when the vacuum suction system is started, the pressure inside the positioning column decreases, causing the piston column to move vertically upward. At this time, the elastic element is in a compressed state. When the vacuum suction system is closed, the restoring force of the elastic element pushes the piston column to move vertically downward, thereby driving the piston column.
[0018] Preferably, the vacuum suction system includes a vent pipe and a control switch. The vent pipe is connected to the internal space of the positioning column, and the control switch is disposed on the vent pipe to control the opening and closing of the vent.
[0019] By adopting the above technical solution, the control switch is set on the vent pipe to control the opening and closing of the vent, thereby driving the piston rod.
[0020] Preferably, the upper ends of the two positioning posts are fixedly fitted with limiting collars, and the bottom end faces of the two limiting collars are located on the same horizontal plane.
[0021] By adopting the above technical solution, the limiting collar limits the depth of the positioning post inserted into the positioning groove, so that the pressure foot cup is connected to the positioning post in a horizontal state, which helps to improve the accuracy of the position when the pressure foot cup and the mounting base are fixedly connected.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By setting up positioning components, snap-fit components, and a control system, when it is necessary to install the pressure foot cup on the mounting base, the control system first controls the snap-fit component to open so that the positioning component can connect the pressure foot cup to the mounting base in a horizontal state. Then, the control system controls the snap-fit component to close so that the pressure foot cup is fixed on the mounting base. This is convenient and quick, and the snap-fit method of fixing the connection will not cause wear. It is difficult for the pressure foot cup and the mounting base to loosen, which helps to improve the stability and accuracy of drilling operations.
[0024] 2. By setting positioning posts and positioning slots, the two positioning posts on the lower surface of the mounting base are respectively inserted into the two positioning slots on the pressure foot cup, so as to realize the positioning of the pressure foot cup and the mounting base during the installation process, which helps to improve the stability of the subsequent snap-fit process.
[0025] 3. By setting a retaining bead and a retaining groove, when the positioning pin is inserted into the positioning groove, the retaining bead protrudes from the through hole and is locked into the retaining groove, so as to realize the snap-locked connection of the pressure foot cup on the mounting base, which has strong stability and is not easy to wear.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0034] This application discloses an installation structure for a pressure foot cup, referring to... Figure 1 and Figure 2 The system includes a pressure foot cup 1 and a mounting base 2. The mounting base 2 is used to horizontally support and fix the pressure foot cup 1. The pressure foot cup 1 adopts a commonly used PCB board punching and fixing structure, which will not be described in detail here. The mounting structure of the pressure foot cup 1 also includes a quick-release mechanism 3 for quickly assembling and disassembling the pressure foot cup 1 and the mounting base 2. Specifically, the quick-release mechanism 3 includes a positioning component 31, a snap-fit component 32, and a control system 33. The positioning component 31 is set between the pressure foot cup 1 and the mounting base 2 to connect the pressure foot cup 1 to the mounting base 2 in a horizontal state. The snap-fit component 32 is set on the positioning component 31 to quickly fix the pressure foot cup 1 to the mounting base 2. The control system 33 is connected to the mounting base 2 to control the opening and closing of the snap-fit component 32, so that the assembly and disassembly process of the pressure foot cup 1 and the mounting base 2 is simple and convenient, and the fixed connection method will not cause wear. It is difficult for the pressure foot cup 1 and the mounting base 2 to loosen, which helps to improve the stability and accuracy of drilling operations.
[0035] Reference Figure 2 and Figure 3The positioning component 31 includes two positioning posts 311, which are vertically fixed to both sides of the lower surface of the mounting base 2. Simultaneously, when the pressure foot cup 1 is placed horizontally, positioning grooves 4 are formed on opposite sides for the two positioning posts 311 to be inserted into. The positions of the two positioning grooves 4 correspond to the positions of the two positioning posts 311, thus achieving the positioning operation when the pressure foot cup 1 and the mounting base 2 are connected. Furthermore, a limiting collar 7 is fixedly fitted onto the upper end of each of the two positioning posts 311, and the bottom end faces of the two limiting collars 7 are located on the same horizontal plane to limit the connection position between the pressure foot cup 1 and the mounting base 2, ensuring that the pressure foot cup 1 is in a horizontal state when positioning is completed.
[0036] Reference Figure 2 and Figure 3 The snap-fit assembly 32 includes a plurality of snap-fit beads 321. The positioning post 311 is hollow. The side wall of the positioning post 311 is provided with a plurality of through holes 5 for the snap-fit beads 321 to protrude. In this embodiment, the number of snap-fit beads 321 on each positioning post 311 is set to three. The number of through holes 5 on the side wall of each positioning post 311 is correspondingly set to three. The three through holes 5 are evenly spaced around the side wall of the positioning post 311. The control system 33 is used to control whether the snap-fit beads 321 protrude from the through holes 5. At the same time, the groove wall of the positioning groove 4 is provided with a snap-fit groove 6 for the snap-fit beads 321 to snap into. When positioning operations are required for the pressure foot cup 1 and the mounting base 2, the control system 33 controls the retaining bead 321 not to protrude from the through hole 5, so that the positioning pin 311 can be inserted into the positioning groove 4. After the positioning operation is completed, the position of the retaining bead 321 is aligned with the position of the groove 6, and the control system 33 controls the retaining bead 321 to protrude from the through hole 5, so that the protruding through hole 5 is engaged in the groove 6, making it difficult to separate the pressure foot cup 1 from the mounting base 2.
[0037] Reference Figure 2 and Figure 4 The control system 33 includes a pushing component and a driving assembly 332. The pushing component is movably disposed inside the positioning post 311 to push the retaining bead 321. The driving assembly 332 is connected to the positioning post 311 to drive the pushing component to move vertically up and down. In this embodiment, the pushing component is a piston post 331. The bottom of the piston post 331 is shaped like an inverted frustum, and the bottom sidewall of the piston post 331 abuts against the retaining bead 321. The driving assembly 332 drives the piston post 331 to move vertically upward so that the retaining bead 321 can enter the positioning post 311 to avoid obstructing the positioning operation of the positioning post 311 and the positioning groove 4. The driving assembly 332 drives the piston post 331 to move vertically downward so that the bottom sidewall of the piston post 331 pushes the retaining bead 321. The retaining bead 321 protrudes from the through hole 5 and is engaged in the retaining groove 6 to achieve a locking and fixing.
[0038] Reference Figure 4 and Figure 5The drive assembly 332 includes a vacuum suction system 3321 and an elastic element 3322. The top of the elastic element 3322 is fixedly connected to the top of the internal space of the positioning column 311, and the bottom of the elastic element 3322 is fixedly connected to the top of the piston column 331. The vacuum suction system 3321 is connected to the internal space of the positioning column 311. In this embodiment, the vacuum suction system 3321 includes a vent pipe 33211 and a control switch 33212. The vent pipe 33211 is connected to the internal space of the positioning column 311, and the control switch 33212 is disposed on the vent pipe 33211 to control the opening and closing of the vent. When the operator opens the vent pipe 33211 via control switch 33212, the pressure inside the positioning column 311 decreases, and the piston column 331 moves vertically upward to facilitate the positioning operation of the pressure foot cup 1 and the mounting base 2. At this time, the elastic element 3322 is in a compressed state. When the operator closes the vent pipe 33211 via control switch 33212, the restoring force of the elastic element 3322 pushes the piston column 331 vertically downward, causing the piston column 331 to press the retaining ball 321 out of the through hole 5 and into the retaining groove 6 to achieve a fixed connection between the pressure foot cup 1 and the mounting base 2. In this embodiment, the elastic element 3322 is selected as a spring sheet.
[0039] The implementation principle of the installation structure of the presser cup in this application embodiment is as follows: When it is necessary to install the presser cup 1 on the mounting base 2, the control system 33 first controls the snap-fit component 32 to open so that the positioning component 31 can connect the presser cup 1 to the mounting base 2 in a horizontal state. Then, the control system 33 controls the snap-fit component 32 to close so that the presser cup 1 is fixed on the mounting base 2. This is convenient and quick, and the snap-fit method of fixing the connection will not cause wear. It is difficult for the presser cup 1 and the mounting base 2 to loosen, which helps to improve the stability and accuracy of drilling operations.
[0040] 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.
