Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile processing, in particular to integrated aluminum profile positioning drilling and tapping equipment based on automatic drill bit replacement. Background Art

[0002] Aluminum profiles are widely used in construction, transportation, electronics, mechanical equipment and other fields due to their advantages such as light weight, corrosion resistance and good thermal conductivity.

[0003] In order to facilitate the subsequent installation of aluminum profiles, drilling and tapping are generally performed at the corresponding positions of the aluminum profiles after they are formed. A drilling and tapping machine is required for this purpose. Due to the different hole diameters of drilling and tapping, most existing drilling and tapping machines are equipped with multiple sets of corresponding drill bits and tapping heads to facilitate convenient switching when needed.

[0004] These drill bits and tapping heads of predetermined specifications are generally inserted on a loading plate, and the stepper motor drives the loading plate to move to achieve the switching of the cutting head and the tapping head. However, the step angle of the stepper motor is generally between 3% and 5%. When the number of drill bits and tapping heads of different specifications is large, the diameter of the loading plate will also increase. At this time, the error caused by the stepper motor driving the loading plate to rotate will also be greater, resulting in an increase in the misalignment between the rotating seat of the drilling and tapping machine and the drill bits and tapping heads, thereby affecting the combination of the two. In severe cases, the rotating seat or the loading plate is damaged, affecting subsequent use. Summary of the invention

[0005] The purpose of the present invention is to provide an integrated device for positioning, drilling and tapping of aluminum profiles based on automatic drill bit replacement, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0011] A driving assembly is connected to the loading disk and the locking assembly. When the first driving member and the second driving member move toward each other, the driving assembly can release the circumferential locking of the loading disk by the locking assembly and drive the loading disk to rotate by a predetermined angle.

When the double-headed cylinder is actuated, it can drive the two groups of clamping members to move closer to or away from each other.

[0014] As a further solution of the present invention: a supporting portion is fixed to the base along its length direction, and an inclined portion is provided on the clamping member. When the two groups of the clamping members move toward each other, the inclined portion can abut against the edge of the aluminum profile placed on the supporting portion.

[0016] The locking assembly comprises a positioning plate coaxially fixedly connected to the rotating shaft of the loading plate, and the positioning plate is provided with a locking groove matching the loading position;

[0017] The locking assembly also includes a connecting frame connected to the second driving member, the connecting frame is rotatably connected to the rotating shaft of the loading disk, and an energy storage structure is also provided on the connecting frame. A locking shaft is rotatably mounted on the energy storage structure, and the locking shaft cooperates with the locking groove to enable the loading disk to be circumferentially locked.

[0018] As a further solution of the present invention: the energy storage structure includes a guide member fixedly mounted on the connecting frame, a connecting member is slidably mounted on the guide member, the connecting member is rotatably connected to the locking shaft, and the connecting member is connected to the driving assembly;

[0019] A transverse shaft slidably connected to the connecting member is also provided in the guide member, and a first cylindrical spring is sleeved on the transverse shaft. One end of the first cylindrical spring is connected to the side wall of the guide member, and the other end is connected to the connecting member.

[0020] As a further solution of the present invention: a plurality of groups of positioning grooves are circumferentially and equidistantly arranged on the side wall of the upper end of the drilling tool, and an upwardly expanding spiral inclined surface is formed at the opening of the positioning groove, and two groups of the spiral inclined surfaces located between two adjacent groups of the positioning grooves intersect;

[0021] The interior of the rotating seat is a hollow structure, and a plurality of groups of convex shafts are arranged on the inner wall of the rotating seat. The convex shafts are adapted to the positioning grooves, and the spiral inclined surface can guide the convex shafts to enter the positioning grooves.

[0022] As a further solution of the present invention: the driving assembly comprises a bracket fixedly mounted on the connecting frame, a transverse frame is slidably mounted on the bracket, and the transverse frame is connected to the bracket via a second cylindrical spring;

[0023] The driving assembly also includes a pushing structure for driving the locking shaft to move away from the locking groove and a one-way connection structure for driving the rotating shaft of the loading disk to rotate. After the pushing structure separates the locking shaft from the locking groove, the one-way connection structure is activated.

[0024] As a further solution of the present invention: the pushing structure includes a follower fixedly connected to the transverse frame, a deflection member is rotatably mounted on one end of the follower, and the follower and the deflection member are connected via an elastic sheet;

[0025] The follower and the deflector are adapted to the abutment shaft rotating on the connecting member;

[0026] The pushing structure further comprises an abutment sleeve arranged between the deflection member and the follower, wherein the abutment sleeve can make the deflection member deflect unidirectionally relative to the follower.

[0027] As a further solution of the present invention: the abutment kit includes an abutment surface formed on the follower and a right-angle abutment portion provided on the deflection member, and the right-angle abutment portion is adapted to the abutment surface.

[0028] As a further solution of the present invention: the one-way connection structure includes a ratchet wheel coaxially fixedly connected to the rotating shaft of the loading plate and a ratchet plate connected to the transverse frame.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] By setting the clamping assembly, on the one hand, it is possible to avoid the presence of a virtual position between the aluminum profile and the supporting part after clamping, which causes the aluminum profile to move downward when the drill acts on the aluminum profile, resulting in deviation in the drilling and tapping position during drilling and tapping. On the other hand, the aluminum profile is not completely straight after forming, and the above-mentioned setting can keep the aluminum profile straight during drilling and tapping, thereby ensuring that the coaxiality of the corresponding hole position can be higher during the installation process, which is convenient for subsequent installation operations.

[0031] The locking assembly is provided to achieve circumferential locking of the loading plate, so that when the loading plate moves to the bottom of the rotating seat, one set of drilling tools can be kept in a coaxial state with the rotating seat, and then when the rotating seat moves down to combine with the drilling tools, the two can be combined smoothly, avoiding the failure of the combination of the two due to non-coaxiality and causing damage to the structure of the rotating seat or the loading plate;

[0032] By setting up the driving assembly, when the first driving member and the second driving member move toward each other, the deflection member can first abut against the abutment shaft to release the circumferential locking of the loading disc, and after the loading disc rotates a small angle, the locking shaft can roll and fit with the circumferential side wall of the positioning disc, so that when the loading disc moves a predetermined angle, the locking shaft can be immediately inserted into the corresponding locking groove to achieve circumferential locking of the loading disc again, thereby preventing the positioning disc from continuing to rotate after rotating to a predetermined angle due to inertia, resulting in the inability to lock the positioning disc and the loading disc, and the locking position is incorrect, thereby improving the stability of drilling tool switching and the accuracy of the position after switching.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0046] See also Figures 1 to 10 In an embodiment of the present invention, an integrated device for positioning, drilling and tapping of aluminum profiles based on automatic drill bit replacement includes: a base 1, a first driving member 7 and a second driving member 8, a locking assembly, and a driving assembly;

[0047] The base 1 is provided with a clamping assembly for fixing the aluminum profile, and the clamping assembly includes two groups of slide grooves 101 symmetrically arranged on the base 1, two groups of sliding connection parts 2 are slidably installed in the slide grooves 101, and the sliding connection parts 2 are provided with clamping members 5;

[0048] The clamping assembly also includes a double-headed cylinder 4 fixedly mounted on the base 1, and two groups of traction rods 3 are rotatably mounted on the action end of the double-headed cylinder 4, and one end of the traction rod 3 away from the double-headed cylinder 4 is rotatably connected to the sliding connection part 2, and when the double-headed cylinder 4 is actuated, it can drive the two groups of the clamping members 5 to move closer to or away from each other;

[0049] When in use, by controlling the movement of the double-headed cylinder 4, the traction rod 3 connected thereto can be driven to move, and the two groups of sliding connection parts 2 arranged in the same group of slide grooves 101 can be driven to move closer to or away from each other, so that the two groups of clamping parts 5 can move closer to or away from each other, thereby clamping and positioning the aluminum profile, improving the position stability of the aluminum profile during the drilling and tapping process, and ensuring the accuracy of drilling and tapping.

[0050] The base 1 is fixed with a supporting portion 6 along its length direction, and the clamping member 5 is provided with an inclined portion 501 . When the two groups of clamping members 5 move toward each other, the inclined portion 501 can abut against the edge of the aluminum profile placed on the supporting portion 6 .

[0051] In the initial state, the aluminum profile is placed on the supporting part 6. At this time, the position where the aluminum profile is not in contact with the supporting part 6 is in a suspended state, so that when the drill 12 acts on the aluminum profile and penetrates the aluminum profile, it will not directly act on the base 1, thereby preventing damage to the structure of the base 1 or damage to the structure of the drill 12 itself.

[0052] Furthermore, when the aluminum profile is placed on the supporting portion 6 and the two groups of clamps 5 move toward each other, the inclined portion 501 on the clamps 5 can act on the edge of the aluminum profile, so that the aluminum profile is pressurized and fits with the supporting portion 6. On the one hand, this can avoid the existence of a virtual position between the aluminum profile and the supporting portion 6 after clamping, which causes the aluminum profile to move downward when the drill 12 acts on the aluminum profile, resulting in deviations in the drilling and tapping positions during drilling and tapping. On the other hand, the aluminum profile is not completely straight after being formed, and the above-mentioned setting can keep the aluminum profile straight during drilling and tapping, thereby ensuring that the coaxiality of the corresponding hole positions can be higher during the installation process, which is convenient for subsequent installation operations.

[0053] See also Figure 1 , Fig. 9 , a first driving member 7 and a second driving member 8 are arranged on the base 1 and can move along the length direction of the base 1, the first driving member 7 is connected to a third driving member 9, in detail, the third driving member 9 can move along the vertical direction of the space on the first driving member 7, a loading disk 11 is rotatably mounted on the second driving member 8, a plurality of groups of loading positions 1101 are equidistantly arranged on the loading disk 11, a drilling tool 12 can be placed on the loading position 1101, wherein the specifications of the drilling tool 12 are sequentially changed according to the circumferential direction of the loading disk 11, so that when the loading disk 11 performs a rotation action, the drilling tool 12 of the corresponding specifications can be sequentially made coaxial with the rotating seat 10;

[0054] The locking assembly is connected to the loading plate 11, and the locking assembly can lock the loading plate 11 circumferentially, so that when the loading plate 11 moves to the lower part of the third driving member 9, the drilling tool 12 arranged on the loading plate 11 can be coaxial with the rotating seat 10 arranged at the lower part of the third driving member 9;

[0055] It is worth noting that the third driving member 9 has a built-in electromagnetic attraction device or a negative pressure adsorption device (neither of which is shown in the figure), so that after the third driving member 9 drives the rotating seat 10 to move downward and abut against the drill tool 12 coaxially, the electromagnetic attraction device or the negative pressure adsorption device can attract or adsorb the drill tool 12, so that when the third driving member 9 moves upward, it can drive the corresponding drill tool 12 to rise and perform drilling or tapping actions.

[0056] The locking assembly comprises a positioning plate 19 coaxially fixedly connected to the rotating shaft of the loading plate 11, and the positioning plate 19 is provided with a locking groove 1901 matching the loading position 1101;

[0057] The locking assembly also includes a connecting frame 13 connected to the second driving member 8, and the connecting frame 13 is rotatably connected to the rotating shaft of the loading disk 11. The connecting frame 13 is also provided with an energy storage structure, and a locking shaft 18 is rotatably mounted on the energy storage structure. The locking shaft 18 cooperates with the locking groove 1901 to enable the loading disk 11 to be circumferentially locked.

[0058] In the initial state, the energy storage structure has a tendency to drive the locking shaft 18 to move toward the rotating shaft of the loading disk 11, so that the locking shaft 18 has a force driven to move toward the rotating shaft of the loading disk 11. Driven by this force, the locking shaft 18 can abut against the end of the locking groove 1901. At the same time, in this state, the locking shaft 18 and the locking groove 1901 are coplanar along their longitudinal axes and the rotating shaft of the loading disk 11, so that when the locking shaft 18 abuts against the locking groove 1901, the positioning disk 19 can be locked, thereby achieving circumferential locking of the loading disk 11, so that when the loading disk 11 moves to the bottom of the rotating seat 10, it can ensure that one group of drilling tools 12 and the rotating seat 10 remain in a coaxial state, and then when the rotating seat 10 moves down to combine with the drilling tools 12, the two can be combined smoothly, avoiding the failure of the combination of the two due to their non-coaxiality and causing damage to the structure of the rotating seat 10 or the loading disk 11.

[0059] The energy storage structure includes a guide member 14 fixedly mounted on the connecting frame 13, a connecting member 17 is slidably mounted on the guide member 14, the connecting member 17 is rotatably connected to the locking shaft 18, and the connecting member 17 is connected to the driving assembly;

[0060] The guide member 14 is further provided with a transverse shaft 15 slidably connected to the connecting member 17 . The transverse shaft 15 is sleeved with a first cylindrical spring 16 . One end of the first cylindrical spring 16 is connected to the side wall of the guide member 14 , and the other end is connected to the connecting member 17 .

[0061] In the initial state, the first cylindrical spring 16 is in a compressed state. At this time, the first cylindrical spring 16 has a force to drive the connecting member 17 to move toward the rotating shaft of the loading disk 11 to ensure the combination stability of the locking shaft 18 and the locking groove 1901, and to ensure that the rotating seat 10 can be smoothly combined with the drilling tool 12 when moving downward.

[0062] Furthermore, when the driving assembly is in action, it can act on the connecting member 17 to move the connecting member 17 away from the rotating shaft of the loading disk 11. At this time, the locking shaft 18 can be separated from the locking groove 1901, thereby releasing the circumferential locking state of the loading disk 11, and after the loading disk 11 rotates by a predetermined angle, the locking shaft 18 can be combined with another locking groove 1901, and the circumferential locking of the loading disk 11 is achieved again, that is, after the loading disk 11 rotates by an angle to change the position of the corresponding drilling tool 12, the locking shaft 18 can be combined with the corresponding locking groove 1901, and the circumferential locking of the loading disk 11 is achieved again, thereby improving the positioning accuracy of the loading disk 11.

[0063] See also Figure 6-7 , a plurality of groups of positioning grooves 1201 are circumferentially and equidistantly arranged on the side wall of the upper end of the drilling tool 12, and an upwardly expanding spiral inclined surface 1202 is formed at the opening of the positioning groove 1201, and two groups of the spiral inclined surfaces 1202 located between two adjacent groups of the positioning grooves 1201 intersect;

[0064] The interior of the rotating seat 10 is a hollow structure, and a plurality of groups of convex shafts 1001 are arranged on the inner wall of the rotating seat 10 . The convex shafts 1001 are adapted to the positioning grooves 1201 , and the spiral inclined surface 1202 can guide the convex shafts 1001 to enter the positioning grooves 1201 .

[0065] After the position of the corresponding drilling tool 12 is switched, when the loading plate 11 moves toward the rotating seat 10, the corresponding drilling tool 12 can be ensured to be coaxial with the rotating seat 10 when moving to the end of the stroke. At this time, the third driving member 9 can drive the rotating seat 10 to move downward until the rotating seat 10 can fit with the drilling tool 12, and in the fitting process, the spiral inclined surface 1202 can cooperate with the cam 1001 to guide the cam 1001 to enter the positioning groove 1201, so that the cooperation between the spiral inclined surface 1202 and the cam 1001 has a certain anti-fool effect, ensuring that the cam 1001 can smoothly enter the positioning groove 1201, and when the cam 1001 enters the positioning groove 1201, axial locking is achieved between the rotating seat 10 and the drilling tool 12, thereby ensuring that when the rotating seat 10 rotates, the drilling tool 12 and the rotating seat 10 can be driven to rotate synchronously through the cooperation between the cam 1001 and the positioning groove 1201, thereby improving the consistency of their movements and the drilling and tapping effects.

[0066] See also Figure 2 , Figure 5 , Figure 8 to Figure 10 The driving assembly is connected to the loading tray 11 and the locking assembly. When the first driving member 7 and the second driving member 8 move toward each other, the driving assembly can release the circumferential locking of the loading tray 11 by the locking assembly and drive the loading tray 11 to rotate by a predetermined angle;

[0067] The driving assembly includes a bracket 27 fixedly mounted on the connecting frame 13, a transverse frame 26 is slidably mounted on the bracket 27, the transverse frame 26 and the bracket 27 are connected via a second cylindrical spring 28, and a roller 29 is rotatably mounted on the end of the transverse frame 26, and the roller 29 is adapted to the abutment plate 30 provided on the third driving member 9;

[0068] The driving assembly also includes a pushing structure for driving the locking shaft 18 to move away from the locking groove 1901 and a one-way connection structure for driving the rotating shaft of the loading disk 11 to rotate. After the pushing structure separates the locking shaft 18 from the locking groove 1901, the one-way connection structure is activated.

[0069] In the initial state, the second cylindrical spring 28 is in a natural state. At this time, the pushing structure and the one-way connection structure are both in an uncoupled state, and in this state, the loading plate 11 can maintain a stable circumferential locking state. When the drilling tool 12 needs to be switched, the second driving member 8 and the first driving member 7 are controlled to move close to each other, so that when the roller 29 abuts against the abutment plate 30, the transverse frame 26 will move relative to the bracket 27. At this time, the second cylindrical spring 28 can be stretched, and the pushing structure and the one-way connection structure can be combined in sequence, so that the locking shaft 18 can first be separated from the locking groove 1901 and release the circumferential locking of the loading plate 11, and then the loading plate 11 rotates a certain angle to switch the corresponding drilling tool 12 to the corresponding position, and finally the locking shaft 18 is combined with another locking groove 1901 again, and the loading plate 11 is locked again, so that the corresponding drilling tool 12 can be switched before being coaxial with the rotating seat 10, as follows:

[0070] The pushing structure includes a follower 22 fixedly connected to the transverse frame 26, a deflection member 21 is rotatably mounted on one end of the follower 22, and the follower 22 and the deflection member 21 are connected via an elastic sheet 23;

[0071] The follower 22 and the deflector 21 are adapted to the abutment shaft 20 rotating on the connecting member 17;

[0072] The pushing structure also includes an abutment kit arranged between the deflection member 21 and the follower 22, and the abutment kit can make the deflection member 21 unidirectionally deflect relative to the follower 22. The abutment kit includes an abutment surface 2201 formed on the follower 22 and a right-angle abutment portion 2101 arranged on the deflection member 21, and the right-angle abutment portion 2101 is adapted to the abutment surface 2201.

[0073] The one-way connection structure includes a ratchet wheel 24 coaxially fixedly connected to the rotating shaft of the loading plate 11 and a ratchet plate 25 connected to the transverse frame 26 .

[0074] In the initial state, the deflection member 21 and the abutment shaft 20 are in a separated state, and the ratchet plate 25 and the ratchet wheel 24 are also in a separated state. At this time, the locking shaft 18 is placed in the locking groove 1901. When the transverse frame 26 moves relative to the bracket 27, the abutment shaft 20 will first abut against the deflection member 21. At this time, the abutment surface 2201 and the right-angle abutment portion 2101 are in an abutment state, so that the deflection member 21 cannot deflect. With the movement of the transverse frame 26, the abutment shaft 20 can move toward the follower 22 along the length direction of the deflection member 21, so that the locking shaft 18 is separated from the locking groove 1901. Then, when the ratchet plate 25 and the ratchet wheel 24 are combined, the loading plate 1 1 can be deflected, and after deflecting a small angle, the abutment shaft 20 moves to the end of the follower 22 away from the deflection member 21, and is separated from the follower 22. At this time, under the action of the first cylindrical spring 16, the locking shaft 18 is reset to roll with the circumferential side wall of the positioning disk 19, and as the ratchet plate 25 continues to move and the positioning disk 19 is rotated, after another locking groove 1901 is aligned with the locking shaft 18, the locking shaft 18 can be immediately inserted into the locking groove 1901, thereby preventing the positioning disk 19 from continuing to rotate after rotating to a predetermined angle due to inertia, resulting in the inability to lock the positioning disk 19 and the loading disk 11, and causing the locking position to be incorrect.

[0075] When the loading plate 11 moves until the locking shaft 18 enters into another locking groove 1901, the position between the first driving member 7 and the second driving member 8 is constant. At this time, the third driving member 9 moves downward to allow the rotating seat 10 to be combined with the drilling tool 12. During this process, the roller 29 can roll on the abutment plate 30.

[0076] When the first driving member 7 and the second driving member 8 move away from each other, the second cylindrical spring 28 will release its elastic potential energy to reset the transverse frame 26. At this time, the ratchet plate 25 will not drive the ratchet wheel 24 to rotate. At the same time, when the abutment shaft 20 abuts against the deflection member 21, the deflection member 21 can be driven to rotate relative to the follower 22. After the abutment shaft 20 and the deflection member 21 are separated, the deflection member 21 can be reset under the action of the elastic sheet 23, so that the above steps can be repeated the next time the first driving member 7 and the second driving member 8 move closer to each other.

[0077] Through the above arrangement, when the first driving member 7 and the second driving member 8 move toward each other, the deflection member 21 can first abut against the abutment shaft 20, thereby releasing the circumferential locking of the loading disk 11, and after the loading disk 11 rotates a small angle, the locking shaft 18 can roll and fit with the circumferential side wall of the positioning disk 19, so that when the loading disk 11 moves a predetermined angle, the locking shaft 18 can be immediately inserted into the corresponding locking groove 1901 to achieve circumferential locking of the loading disk 11 again, thereby preventing the positioning disk 19 from continuing to rotate after rotating to a predetermined angle due to inertia, resulting in the inability to lock the positioning disk 19 and the loading disk 11, resulting in incorrect locking position, thereby improving the stability of the drilling tool 12 switching and the accuracy of the position after switching.

[0078] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0079] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
