In addition, in the context, it should also be understood that when referring to an element connected to another element "on" or "under", it can not only be directly connected to another element "on" or "under", but also indirectly connected to another element "on" or "under" through an intermediate element.

[0048] With the development of science and technology, the use range of the drilling machine is more and more widely. In the production process of the circuit board, the drilling machine is used to process the circuit board. However, the pressure foot on the existing drilling machine often needs to be replaced regularly by manual operation. The manual replacement of the pressure foot not only costs more time, but also has certain operation risk. If the pressure foot is not replaced in time, the quality of the circuit board will be adversely affected, and even the circuit board will be scrapped.

[0049] In view of this, the embodiment of the present application provides a pressure foot replacement assembly for solving the problem that the pressure foot of the drilling machine cannot be automatically replaced.

[0050] As shown in Figure 1 The embodiment of the present application provides a pressure foot replacement assembly applied to a drilling machine. The drilling machine includes a main shaft (not shown in the figure), and the main shaft is provided with a pressure foot 4. The pressure foot replacement assembly includes a main body part 1, and the main body part 1 is provided with a first accommodating cavity 2 and a second accommodating cavity 3. Specifically, according to the actual situation of the drilling machine, a plurality of first accommodating cavities and second accommodating cavities can be arranged on the drilling machine. The first accommodating cavity 2 is provided with a limiting part 21, and the limiting part 21 is located on the side wall of at least one side of the first accommodating cavity 2. The limiting part 21 has a preset distance with the bottom wall of the first accommodating cavity 2. One side of the first accommodating cavity 2 along the length direction X is provided with an opening. When the main shaft moves away from the opening along the first accommodating cavity 2, the limiting part 21 contacts with the pressure foot 4 of the main shaft, so as to disassemble the pressure foot 4. The second accommodating cavity 3 is used to store the unused pressure foot 4. When the main shaft moves to the second accommodating cavity 3, the pressure foot 4 stored in the second accommodating cavity 3 can cooperate with the main shaft.

[0051] The main shaft of the drilling machine is provided with a chip suction cover (not shown in the figure), and the pressure foot 4 is installed on the chip suction cover. The main shaft can move together with the chip suction cover. The drilling machine is provided with a pressure foot replacement assembly. The pressure foot 4 assembly includes a main body 1, and the main body 1 is provided with a first accommodating cavity 2 and a second accommodating cavity 3. The first accommodating cavity 2 can be connected with the second accommodating cavity 3 or can be independently arranged. The first accommodating cavity 2 is provided with a limiting portion 21. The limiting portion 21 is located on the side wall of at least one side of the first accommodating cavity 2. The limiting portion 21 and the bottom wall of the first accommodating cavity 2 have a predetermined distance, so that the pressure foot 4 can pass between the limiting portion 21 and the bottom wall of the first accommodating cavity 2, thereby enabling the pressure foot 4 to move along the first accommodating cavity 2. Specifically, the limiting portion 21 and the first accommodating cavity 2 can form a T-shaped groove structure. The pressure foot 4 can cooperate with the T-shaped groove and can move along the T-shaped groove. The first accommodating cavity 2 is provided with an opening. The pressure foot 4 can enter the first accommodating cavity 2 through the opening. As the main shaft moves away from the opening, the limiting portion 21 can contact the pressure foot 4. When the limiting portion 21 contacts the pressure foot 4, the limiting portion 21 limits the pressure foot. When the main shaft moves along the height direction Z, the pressure foot 4 can be separated from the main shaft due to the action of the limiting portion 21, thereby completing the disassembly of the pressure foot 4. The pressure foot 4 separated from the main shaft can be stored in the first accommodating cavity 2. After the main shaft is separated from the pressure foot 4, the main shaft continues to move to the second accommodating cavity 3. The second accommodating cavity 3 stores unused pressure feet 4. The main shaft can cooperate with the unused pressure feet 4, so that the pressure feet 4 are installed on the main shaft, thereby completing the replacement of the pressure feet 4. By arranging the pressure foot replacement assembly on the drilling machine, the labor demand is reduced, and the accuracy and efficiency of replacing the pressure foot 4 are improved, which is conducive to improving the degree of automation. At the same time, using the pressure foot replacement assembly is also conducive to improving the frequency of replacing the pressure foot 4 on the main shaft, reducing the possibility of excessive wear of the pressure foot 4, thereby reducing the possibility of poor drilling and chip removal when the drilling machine processes the circuit board, and also reducing the failure rate of the drilling machine, which is conducive to improving the processing efficiency and production quality of the circuit board.

[0052] As Figure 2 shown, in a possible implementation, the limiting portion 21 is arranged on the side wall of each side of the first accommodating cavity 2.

[0053] The first accommodating cavity 2 is provided with the limiting portion 21, and the limiting portion 21 can be arranged on the side wall of each side of the first accommodating cavity 2. By arranging two limiting portions 21, the disassembly of the pressure foot 4 on the main shaft is facilitated, the efficiency of disassembling the pressure foot 4 is improved, and the disassembly process is more stable, thereby reducing the possibility of the pressure foot 4 falling off from the first accommodating cavity 2.

[0054] In a possible implementation, the limiting part 21 is provided with a guide surface 211, which can be in contact with the pressure foot 4, for disengaging the pressure foot 4 from the main shaft.

[0055] Specifically, as shown in Figure 2 the height of at least part of the limiting part 21 gradually decreases in the direction away from the opening, that is, a T-shaped groove slope is formed on the T-shaped groove structure formed by the limiting part 21 and the first accommodating cavity 2, the T-shaped groove slope can cooperate with the pressure foot 4, the limiting part 21 is provided with a guide surface 211, which is arranged on the T-shaped groove slope, and the guide surface 211 can cooperate with the pressure foot 4 to disengage the pressure foot 4 from the main shaft during movement of the main shaft in the direction away from the opening. By arranging the pressure foot 4 and the guide surface 211, the cooperation between the limiting part 21 and the pressure foot 4 is facilitated, thereby facilitating the disassembly of the pressure foot 4 from the main shaft.

[0056] As shown in Figure 3 In a possible implementation, the second accommodating cavity 3 further includes a moving piece 31, which can move along the second accommodating cavity 3 to push the pressure foot 4 to a preset position.

[0057] The second accommodating cavity 3 stores unused pressure feet 4, and the second accommodating cavity is further provided with a moving piece 31, which can move along the second accommodating cavity 3 and can push the pressure foot 4 in the second accommodating cavity 3 to move, so that the pressure foot 4 reaches a preset position to facilitate cooperation with the main shaft. By arranging the moving piece 31, the movement of the pressure foot 4 along the second accommodating cavity 3 is facilitated, thereby facilitating the cooperation of the main shaft with the pressure foot 4 and realizing the installation process of the pressure foot 4.

[0058] In a possible implementation, the second accommodating cavity 3 includes a guide rod 32 and an elastic piece 33, the guide rod 32 extends along the length direction X of the second accommodating cavity 3, and the elastic piece 33 is installed on the guide rod 32, and the elastic piece 33 is used to drive the moving piece 31 to move along the guide rod 32.

[0059] The second accommodating cavity 3 further comprises a guide rod 32 and an elastic member 33, which can be a spring. The guide rod 32 extends along the length direction X of the second accommodating cavity, and the elastic member 33 can be sleeved with the guide rod 32 and can move along the guide rod 32 under the action of the elastic force. The elastic member 33 is connected with the moving piece 31, so as to drive the moving piece 31 to move. One end of the moving piece 31 is connected with the elastic member 33, and the other end is connected with the pressure foot 4. When the elastic member 33 drives the moving piece 31 to move along the guide rod 32, the pressure foot 4 can also move with the moving piece 31. When the second accommodating cavity 3 is filled with unused pressure feet 4, the elastic member 33 is in a compressed state. With the pressure foot 4 away from the moving piece 31 being taken away by the main shaft, the elastic member 33 gradually pushes the pressure foot 4 close to the moving piece 31 to the side away from the moving piece 31 under the action of the restoring force, so that the pressure foot 4 reaches the preset position and cooperates with the main shaft. By arranging the guide rod 32 and the elastic member 33, the pressure foot 4 can be pushed to move along the second accommodating part, so that the pressure foot 4 can be automatically replenished, thereby facilitating the cooperation between the pressure foot 4 and the main shaft, and further facilitating the installation process of the pressure foot 4 and improving the installation efficiency.

[0060] As shown in Figure 4 In a possible implementation, the second accommodating cavity 3 comprises a first cavity 34 and a second cavity 35, the first cavity 34 is in communication with the second cavity 35, the width of the first cavity 34 is greater than that of the second cavity 35, the first cavity 34 is used for storing unused pressure feet 4, and the guide rod 32 is located in the second cavity 35.

[0061] The second accommodating cavity 3 is provided with the first cavity 34 and the second cavity 35, the first cavity 34 is connected with the second cavity 35, wherein the width of the first cavity 34 is greater than that of the second cavity 35, the space related to the whole can be understood as a T-shaped groove body, the first cavity 34 is used for storing unused pressure feet 4, and the second cavity 35 is used for accommodating the guide rod 32. By arranging the first cavity 34 and the second cavity 35, the possibility of contact between the pressure foot 4 and the guide rod 32 is reduced, which is conducive to the elastic member 33 pushing the moving piece 31 to move along the guide rod 32, thereby facilitating the moving piece 31 driving the pressure foot 4 to move.

[0062] As shown in Figure 5 In a possible implementation, the second accommodating cavity 3 comprises a positioning member 36, the positioning member 36 is installed on the bottom wall of the first cavity 34, and the positioning member 36 can move relative to the second accommodating cavity 3 along the height direction Z of the main body part 1.

[0063] The second accommodating cavity 3 is provided with a positioning member 36, which is installed on the bottom wall of the first cavity 34. The positioning member 36 can be a spring plunger, which can move relative to the second accommodating cavity 3 along the height direction Z of the main body 1 under the action of the elasticity. The positioning member 36 limits the pressure foot 4 in the second accommodating cavity 3, reduces the possibility of the pressure foot 4 falling from the second accommodating cavity 3, keeps the pressure foot 4 at a preset position, and is beneficial to the cooperation of the pressure foot 4 with the main shaft. When the pressure foot 4 is installed on the main shaft, the pressure foot 4 moves away from the second accommodating cavity 3 with the main shaft. At this time, the positioning member 36 is compressed under the pressure of the pressure foot 4, so that the pressure foot 4 smoothly leaves the second accommodating cavity 3. When the positioning member 36 loses the pressure, it returns to the original length. At this time, at least part of the positioning member 36 is located in the second accommodating cavity 3, thereby limiting the pressure foot 4 in the second accommodating cavity 3. By arranging the positioning member 36, the possibility of the pressure foot 4 falling from the second accommodating cavity 3 is reduced, and the pressure foot 4 is limited, so that the pressure foot 4 is kept at a preset position, thereby facilitating the cooperation with the main shaft and completing the installation process of the pressure foot 4.

[0064] In a possible implementation, the pressure foot replacement assembly includes a first detection part 5, which is used to detect whether the pressure foot 4 reaches a preset position. The first detection part 5 is installed on one side of the second accommodating cavity 3 along the length direction X of the main body 1, and is located on the side of the positioning member 36 close to the moving part 31.

[0065] The pressure foot replacement assembly is also provided with a first detection part 5, which is used to detect whether the pressure foot 4 reaches a preset position. The first detection part 5 can be arranged on the side wall outside the second accommodating cavity 3, and is located on the side of the positioning member 36 close to the moving part 31 along the length direction X of the main body 1. When the first detection part 5 detects that there is a pressure foot 4 at the preset position, the main shaft can move to the preset position, and then the installation process of the pressure foot 4 is performed. If the first detection part 5 does not detect the pressure foot 4, an alarm can be given to remind the staff, thereby reducing the failure rate of the pressure foot replacement assembly. By arranging the first detection part 5, the installation process of the pressure foot 4 is facilitated, thereby improving the installation efficiency of the pressure foot 4.

[0066] In a possible implementation, the pressure foot replacement assembly includes a second detection part (not shown in the figure), which is used to detect whether the main shaft is installed with the pressure foot 4.

[0067] The pressure foot replacement assembly also includes a second detection unit. This second detection unit is used to detect whether the spindle is equipped with pressure foot 4 and to check whether pressure foot 4 is installed correctly. Simultaneously, the second detection unit has an alarm function; if a problem occurs during the removal or installation of pressure foot 4, the second detection unit can promptly sound an alarm to alert personnel, thereby facilitating the replacement of pressure foot 4.

[0068] This application also provides a drilling machine that includes a pressure foot replacement assembly as described above.

[0069] The pressure foot 4 on the chip suction hood of the drilling machine needs to be replaced after a period of use. The drilling machine is equipped with an automatic pressure foot 4 replacement device. During the pressure foot 4 replacement process, the drilling machine spindle first moves to the position of the opening of the first receiving cavity 2, and then moves along the first receiving cavity 2 away from the opening. During the movement, the pressure foot 4 on the spindle enters the first receiving cavity 2 and cooperates with the limiting part 21 of the first receiving cavity 2. Under the action of the guide surface 211, the pressure foot 4 will disengage from the spindle and be temporarily stored in the first receiving cavity 2. After being disengaged from the pressure foot 4, the spindle continues to move to the position of the second detection part. The second detection part will detect whether the pressure foot 4 on the spindle has been removed. If the spindle passes the detection, it will move to the position of the second receiving part, which has a preset position where the spindle can install the pressure foot 4. The second receiving cavity contains unused pressure feet 4. The first detection unit 5 detects a preset position to determine if a pressure foot 4 is present. When the first detection unit 5 detects a pressure foot 4, the spindle begins to press down towards the pressure foot 4. The pressure foot 4 engages with the spindle, and through the downward pressure of the spindle, the pressure foot 4 is installed on the spindle. After the pressure foot 4 is installed, the spindle moves to the position of the second detection unit. At this time, the second detection unit checks whether the pressure foot 4 is installed correctly. If the pressure foot 4 is installed correctly, the replacement of the pressure foot 4 on the chip suction cover of the spindle is completed. If the pressure foot 4 is not installed correctly, the second detection unit will sound an alarm to alert the operator. Simultaneously, when the pressure foot 4 at the preset position is removed by the spindle, the next pressure foot 4 is pushed to the preset position by the elastic member 33 and the moving member 31. The second receiving cavity 3 is provided with a positioning member 36, which limits the pressure foot 4, keeping it in the preset position for easy replacement of the next pressure foot 4. By installing a pressure foot replacement component on the drilling machine, the accuracy and efficiency of pressure foot 4 replacement are improved, and the frequency of pressure foot 4 replacement is increased. This reduces the possibility of drilling machine failure due to untimely pressure foot 4 replacement, and is beneficial to improving the working efficiency of the drilling machine.

[0070] like Figure 6As shown, in one possible implementation, the drill press comprises a main shaft, a pressure foot 4, the pressure foot 4 is provided with a matching part 41, the matching part 41 is used to match with the limiting part 21 of the pressure foot replacement assembly.

[0071] The pressure foot 4 is provided with the matching part 41, the matching part 41 is located on both sides of the pressure foot 4, specifically, the pressure foot 4 can be matched with the limiting part 21 through the matching part 41, so as to disassemble the pressure foot 4 on the main shaft. At the same time, the pressure foot 4 can also be matched with the second containing cavity 3 through the matching part 41, so as to facilitate the installation of the unused pressure foot 4 on the main shaft, thereby reducing the labor demand and improving the degree of automation. It is beneficial to improve the frequency of replacing the pressure foot 4 on the main shaft, and reduce the possibility of excessive wear of the pressure foot 4.

[0072] The application provides a pressure foot replacement assembly and a drill press, wherein the pressure foot replacement assembly is applied to the drill press, the drill press comprises a main shaft, the main shaft is provided with a pressure foot 4, the pressure foot replacement assembly comprises a main body part 1, the main body part 1 is provided with a first containing cavity 2 and a second containing cavity 3, the first containing cavity 2 is provided with a limiting part 21, the limiting part 21 is located on the side wall of at least one side of the first containing cavity 2, and there is a preset distance between the limiting part 21 and the bottom wall of the first containing cavity 2. When the main shaft moves in the direction away from the opening along the first containing cavity 2, the limiting part 21 contacts the pressure foot 4 of the main shaft, which is used to disassemble the pressure foot 4, and the second containing cavity 3 is used to store the unused pressure foot 4. When the main shaft moves to the second containing cavity 3, the pressure foot 4 stored in the second containing cavity 3 can be matched with the main shaft.

[0073] In the above embodiment, by setting the pressure foot replacement assembly on the drill press, the labor demand is reduced, not only the accuracy and efficiency of replacing the pressure foot 4 are improved, but also the degree of automation is improved. At the same time, using the pressure foot replacement assembly is beneficial to improve the frequency of replacing the pressure foot 4 on the main shaft, and reduce the possibility of excessive wear of the pressure foot 4, thereby reducing the possibility of poor drilling and chip removal when the drill press processes the circuit board. And reduce the failure rate of the drill press, which is beneficial to improve the processing efficiency and production quality of the circuit board.
