Description

Technical Field

[0001] The invention relates to the technical field of equipment for manufacturing a power distribution cabinet, and in particular to a drilling and grinding device for a power distribution cabinet which is convenient for disassembly and assembly. Background Art

[0002] Drilling of distribution cabinets mostly refers to punching holes on the back of the distribution cabinet, in order to facilitate the installation of the distribution cabinet. The traditional operation method is that the holes on the back are punched together with the cabinet sheet metal, that is, the installation holes on the back are formed into one piece with the cabinet sheet metal plane using a laser cutting machine or a punching machine. Although it is quick and easy, it is only suitable for installation holes with larger specifications. This is because when the diameter of the installation hole is small, not only the accuracy of laser cutting cannot be guaranteed, but the punch of the smaller-sized punching machine will also often break.

[0003] On the other hand, existing drilling machines, such as drilling machines, can only perform a single drilling operation, and the burrs and flash generated during the drilling process need to be transferred to the next grinding process for operation, which also has the disadvantage of low efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a drilling and grinding device for distribution cabinets which is easy to disassemble and assemble. By utilizing the position limitation formed by the corner clamp seat assembly, in cooperation with the double-position clamp seat assembly and the bottom safety clamp seat assembly, the action of clamping the cabinet downward can be utilized to achieve safe clamping of the cabinet, and the use of the slide frame assembly can be used to achieve rapid disassembly of the cabinet after processing.

[0005] The object of the present invention is achieved through such a technical solution, a drilling and grinding device for a power distribution cabinet that is easy to disassemble and assemble, comprising a base frame, an inner stand component, an angle clamp seat assembly, a double-position clamp seat assembly, a bottom safety clamp seat assembly, a slide frame component and an elastic release component, the double-position clamp seat assembly comprises an inner connecting arm, a middle column and a middle slide seat, the bottom safety clamp seat assembly comprises an outer fixing plate, the slide frame component comprises a main slide, and the elastic release component comprises a push column;

[0006] The inner seat component is fixed to the top of the bottom frame body, and the corners of the square outline formed by the inner seat component at the top of the bottom frame body are all installed with corner clamping seat components;

[0007] The inner lower end of the inner standing seat component is symmetrically rotatably connected with an inner clamp seat, and the top of the bottom frame body is symmetrically rotatably connected with an outer clamp seat, the inner connecting arm is fixed to the outer end of the rotation shaft of the inner clamp seat, the middle column is fixed to one side of the rotation shaft of the outer clamp seat, and the middle column on the same side is slidably connected to the inner connecting arm, the middle sliding seat is symmetrically elastically inserted into the top end of the bottom frame body, and the middle sliding seat on the same side is slidably connected to the middle column, each group of middle sliding seats is also fixedly connected to the bottom of the middle sliding seat, and the top of the bottom frame body is also symmetrically elastically slidably connected to an inclined seat in the direction of the bottom connecting plate, the outer fixed plate is fixedly connected to one side of the inclined seat, the main slide is slidably connected to both sides of the top of the bottom frame body, the outer sides of the two groups of outer fixed plates are commonly fixed with corner fixed plates, and the push column is fixed to the inner top end of the main slide;

[0008] The top of the main slide is equipped with a drilling assembly and a grinding assembly which are transmission-connected. The drilling assembly and the grinding assembly can move toward each other and can drive the grinding assembly to perform grinding when the drilling assembly is drilling.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] The outer contour of the cabinet to be drilled matches the size of the elastic support clip formed by the array corner clamp assembly, and the cabinet can be positioned and placed by utilizing the cooperation between the corners of the cabinet and the corner clamp assembly;

[0011] Under the action of the upward elastic support of the middle sliding seat itself, when there is no external force pushing the middle sliding seat downward, the inner clamping seat and the outer clamping seat can be in a position away from each other and opened under the action of the sliding connection formed between the middle sliding seat and the middle column, and the sliding connection formed between the middle column and the inner connecting arm;

[0012] The inner clamp seat is always located in the inner cavity of the cabinet, and the outer clamp seat is always located outside the cabinet. As the cabinet is inserted between the array corner clamp seat components and moves downward, the center slide seat is pushed downward, so that the inner clamp seat and the outer clamp seat form a rotational movement close to each other, and as the center slide seat moves downward, the bottom connecting plate is driven to move downward. When the back of the inner cavity of the cabinet is in contact with the top of the inner stand component, the bottom connecting plate and the inclined seat form an elastic sliding fit. After the inclined seat extends over the bottom connecting plate, the bottom connecting plate can be clamped. At this time, the inner clamp seat and the outer clamp seat on the same side just cooperate with each other to form a clamping effect on the cavity wall of the cabinet, so that the cabinet can be quickly clamped.

[0013] When clamping the cabinet, the main slide is located at a position that does not interfere with the clamping action. After the cabinet is clamped, the drilling assembly and the grinding assembly can be moved to the drilling position by moving the main slide to perform drilling and grinding work on the back of the cabinet.

[0014] After the drilling and grinding are completed, the main slide is moved to one side to form a space for disassembling the cabinet body, and when the main slide moves to the position of the protruding side of the corner fixing plate, it can just drive the push column and the corner fixing plate to form a sliding cut cooperation, which will drive the outer fixing plate to move, so that the inclined seat is disengaged from the clamping connection with the bottom connecting plate, and under the action of the upward elastic support of the middle slide itself, the middle slide can push the middle column to move upward, and through the sliding cooperation formed by the middle column and the inner connecting arm, the outer clamp seat and the inner clamp seat can be driven to open each other, thereby releasing the clamping of the cabinet body, so that after the drilling and grinding work is completed, as the main slide drives the drilling assembly and the grinding assembly to move to the empty position, the cabinet body can form a passive and fast disassembly work.

[0015] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0016] (1) The present invention installs corner clamping seat assemblies at the corners of the square profile formed with the inner seat member as the center at the top of the bottom frame, so that the inner seat member can form a contact reference with the back of the inner cavity of the cabinet, that is, positioning in the height direction, and the corner clamping seat assemblies can form positioning of the cabinet in the X-axis and Y-axis directions;

[0017] (2) Inner clamping seats and outer clamping seats are screwed in pairs on both sides of the top of the bottom frame. The inner clamping seats are located within the contour of the inner cavity of the cabinet, and the outer clamping seats are located outside the contour of the cabinet. Under the upward elastic support of the middle slide seat, when the cabinet is not clamped, the outer clamping seats and the inner clamping seats are in a relatively outwardly stretched state, which can facilitate the downward movement of the cabinet after the cabinet is clamped between the array corner clamp seat components. At the same time, when the cabinet moves downward to a certain position, it will press against the middle slide seat to push the middle slide seat downward The movement of the middle column can make the middle column rotate downward, and the sliding connection formed by the middle column and the inner connecting arm can drive the outer clamp seat and the inner clamp seat to form a relative clamping action, that is, the downward movement of the cabinet during the clamping process can complete the promotion of the clamping action of the outer clamp seat and the inner clamp seat, so that after the back of the inner cavity of the cabinet body and the top of the inner stand member are in place, the outer clamp seat and the inner clamp seat are just clamped in place, and the inclined seat forms a safe clamping connection with the bottom connecting plate, so that the outer clamp seat and the inner clamp seat can form a safe clamping action;

[0018] (3) The movement of the main slide of the present invention can not only drive the drilling assembly and the grinding assembly to move to the drilling position, but also enable the push column and the protruding side surface of the corner fixing plate to form a sliding fit after the drilling and grinding work is completed. Therefore, when the main slide drives the drilling assembly and the grinding assembly to move to the set empty position, the corner fixing plate is pushed to drive the inclined seat and the bottom connecting plate to disengage the clamping, so that the middle slide is elastically released upward, and the cabinet body that has completed the drilling and grinding work can be automatically ejected, so as to facilitate the purpose of quick disassembly.

The push column 903 is fixed to the inner top end of the main slide 602, and when the main slide 602 is in the working position, it does not contact the side of the corner fixing plate 901. When the main slide 602 moves to the set position, the push column 903 slides and cuts to the protruding side of the corner fixing plate 901, and can release the inclined seat 504 elastically stuck in the top end of the bottom connecting plate 417.

[0043] The top of the main slide 602 is equipped with a drilling assembly 7 and a grinding assembly 8 which are connected by transmission. The drilling assembly 7 and the grinding assembly 8 can move toward each other and can also drive the grinding assembly 8 to perform grinding when the drilling assembly 7 is drilling.

[0044] The top slide rail 701 in the drilling assembly 7 is symmetrically fixed to the top end of the main slide 602, and the bottom end of the top slide 702 is slidably connected to the top slide rail 701;

[0048] A pair of shifting rotary seats 709 are fixedly installed on one side of the top of the main slide 602. A shifting rotary shaft 710 is rotatably connected to each set of shifting rotary seats 709. A shifting toothed belt wheel 711 is inserted and fixed to each set of shifting rotary shaft 710.

[0050] A rotating shaft sleeve 715 is also fixedly installed in the middle of the outer bottom surface of the top slide 702. The rotating shaft of the rotating motor 706 is rotatably inserted in the rotating shaft sleeve 715. The rotating shaft sleeve 715 can improve the accuracy and stability of the rotating shaft of the rotating motor 706.

[0051] The side slide rails 801 in the grinding assembly 8 are fixed in pairs on one side of the upper end of the main slide rail 601, and the side slide seat 802 is slidably connected to the side slide rail 801, and is fixedly connected to the outer side of the lower end of the shifting toothed belt 712 through the side slide connecting seat 803;

[0052] After the shift servo motor 713 is started, the shift toothed belt wheel 711 can be driven to rotate, and the shift toothed belt 712 can be driven to roll, so that the slide seat 714 and the side slide seat 803 can move toward each other, so that after the top slide 702 moves to one side, the side slide seat 802 can move to the other side synchronously;

[0053] The installation position of the side sliding seat 803 relative to the shifting toothed belt 712 and the installation position of the carriage seat 714 relative to the shifting toothed belt 712 can be adjusted, so that the top carriage 702 and the side sliding seat 802 can move toward each other accurately under the drive of the shifting toothed belt 712;

[0054] An outer column rotating seat 804 is fixedly installed on one side of the bottom end of the side sliding seat 802, and an outer rotating cylinder 805 is rotatably connected in the outer column rotating seat 804. The inner rotating plug shaft 806 is slidably inserted in the outer rotating cylinder 805. A top thrust bearing 809 is also fixedly installed on one side of the lower end of the side sliding seat 802. A grinding head 807 and a bottom thrust bearing 808 are fixedly installed on the bottom end of the inner rotating plug shaft 806, and the bottom thrust bearing 808 is located at the upper end of the grinding head 807. A tension spring 810 is sleeved and installed in the inner rotating plug shaft 806, and the top end is fixed to the top thrust bearing 809, and the bottom end is fixed to the bottom thrust bearing 808. A grinding transmission bearing 811 is fixedly installed on the top end of the inner rotating plug shaft 806.

[0055] Under the tension of the tension spring 810, when there is no external force pushing the grinding transmission bearing 811 downward, the grinding head 807 is in the upper limit position, so that after the cabinet 10 is clamped, the grinding head 807 is in a natural position without contact with the cabinet 10;

[0056] The top inner frame of the main slide 602 is fixed with a pair of transmission seats 813, each set of transmission seats 813 is rotatably connected with a transmission toothed belt wheel 814, and a transmission double-sided toothed belt 815 is sleeved and installed between two sets of transmission toothed belt wheels 814;

[0057] The rotating gear sleeve 812 is sleeved and fixed on the outside of the drill chuck 707, and meshes with the outer tooth surface of the transmission double-sided toothed belt 815. In the vertical movement range of the drill chuck 707, the rotating gear sleeve 812 is always in a position meshing with the outer tooth surface of the transmission double-sided toothed belt 815.

The top inner frame of the main slide 602 is also fixed with a pair of frame slides 818. The push frame 817 is slidably connected to the frame slide 818 through the frame slides 819 on both sides of the bottom end. The bottom end of each set of frame slides 819 is fixed with a bottom sleeve 820 to prevent the frame slides 819 and the frame slide 818 from slipping off. The frame slides 819 and the bottom sleeve 820 can be immersed in the inner ring of the transmission double-sided toothed belt 815 without interfering with each other.

[0059] A return spring 821 is also sleeved and installed in each set of frame slide posts 819. The top end of the return spring 821 is fixed to the bottom surface of the push frame 817, and the bottom end is fixed to the top surface of the frame slide seat 818, so that the push frame 817 is in a naturally elastic upward position.

[0060] The slideway 822 is provided in the main body of the pushing frame 817 , the rotating shaft of the rotating motor 706 is inserted in the slideway 822 , and the active thrust bearing 823 is installed and fixed on the outside of the rotating shaft of the rotating motor 706 .

[0061] Here’s how it works:

[0062] The device can realize automatic clamping of the cabinet 10 and rapid disassembly after drilling and grinding work is completed;

[0063] The outer contour of the cabinet 10 to be drilled matches the size of the elastic support clip formed by the array corner clamp assembly 3, and the cabinet 10 can be positioned and placed by utilizing the cooperation between the corners of the cabinet 10 and the corner clamp assembly 3;

[0064] Under the upward elastic support of the middle slide seat 414 itself, when there is no external force pushing the middle slide seat 414 downward, the inner clamp seat 401 and the outer clamp seat 402 are in a position away from each other and open, under the action of the sliding connection formed between the middle slide seat 414 and the middle column 410, and under the action of the sliding connection formed between the middle column 410 and the inner connecting arm 407;

[0065] The inner clamp seat 401 is always located in the inner cavity of the cabinet 10, and the outer clamp seat 402 is always located outside the cabinet 10. As the cabinet 10 is inserted between the array corner clamp seat components 3 and moves downward, the centering slide seat 414 is pushed downward, so that the inner clamp seat 401 and the outer clamp seat 402 form a rotational movement close to each other, and as the center slide seat 414 moves downward, the bottom connecting plate 417 is driven to move downward. When the back of the inner cavity of the cabinet 10 is in place with the top of the inner stand member 2, the bottom connecting plate 417 and the inclined seat 504 can form an elastic sliding fit. After the inclined seat 504 extends over the bottom connecting plate 417, the bottom connecting plate 417 can be clamped. At this time, the inner clamp seat 401 and the outer clamp seat 402 on the same side just cooperate with each other to form a clamping effect on the cavity wall of the cabinet 10, so that the cabinet 10 can be quickly clamped.

[0066] When clamping the cabinet 10, the main slide 602 is located at a position that does not interfere with the clamping action. After the cabinet 10 is clamped, the drilling assembly 7 and the grinding assembly 8 can be moved to the drilling position by moving the main slide 602 to perform drilling and grinding work on the back of the cabinet 10.

[0067] After the drilling and grinding are completed, the main slide 602 is moved to one side to form a disassembly space for the cabinet 10, and when the main slide 602 moves to the position where the corner fixing plate 901 protrudes from the side, it can just drive the push column 903 to form a sliding cut cooperation with the corner fixing plate 901, which will drive the outer fixing plate 506 to move, so that the inclined seat 504 is separated from the clamping connection with the bottom connecting plate 417, and under the action of the upward elastic support of the middle slide 414 itself, the middle slide 414 can push the middle column 410 to move upward, and through the sliding cooperation formed by the middle column 410 and the inner connecting arm 407, the outer clamp seat 402 and the inner clamp seat 401 can be driven to open each other, and the clamping of the cabinet 10 can be released, so that the cabinet 10 can be passively and quickly disassembled after the drilling and grinding work is completed, as the main slide 602 drives the drilling assembly 7 and the grinding assembly 8 to move to the empty position;

[0068] When the rotary motor 706, the drill chuck 707 and the drill bit 708 are in a suspended position without drilling, the active thrust bearing 823 does not contact the top surface of the push frame 817. After the drill bit 708 moves to the drilling height, the active thrust bearing 823 abuts against the top surface of the push frame 817. As the drill bit 708 moves downward, the push frame 817 with natural elasticity upward can be pushed downward, so that the bottom surface of the push frame 817 contacts the grinding transmission bearing 811, and pushes the inner rotating plug shaft 806 and the grinding head 807 to form a downward movement.

[0069] At the same time, the rotating motor 706 drives the drill chuck 707 to rotate, which causes the rotating gear sleeve 812 to form a matching transmission with the transmission double-sided toothed belt 815, driving the continuous rolling of the transmission double-sided toothed belt 815, and the transmission double-sided toothed belt 815 and the passive toothed belt wheel 816 to form a matching transmission, which can drive the rotation of the outer rotating cylinder 805 and the inner rotating plug shaft 806, thereby forming a rotation movement of the grinding head 807 with the drill chuck 707;

[0070] Since the holes on the back of the cabinet 10 are mostly symmetrically distributed, when drilling a hole on one side, the drilling position on the other side can be polished synchronously, so that the drilling and polishing operation can be performed, which can simplify the operation process and save processing time;

[0071] When drilling the symmetrically distributed second hole position, the completed first hole position can be polished synchronously. When polishing the symmetrically distributed second hole position, the drill chuck 707 and the drill bit 708 need to be moved to a position opposite to the polished first hole position.

[0072] The specific structure of the inner seat component 2 and the corner clamp seat assembly 3 is as follows Figure 3 , Figure 4 and Figure 5 As shown, the top plate 202 is fixedly connected to the top of the frame of the bottom frame body 1 through the inner columns 201 at the bottom corners;

[0073] The top plate 202 is made of a soft material, preferably engineering nylon;

[0074] The long side stand 301 and the short side stand 302 are fixed in pairs at the corners of the square outline formed by the inner stand member 2 at the top of the bottom frame 1. The inner side of each set of long side stand 301 and short side stand 302 is commonly fixed with an inner fixed seat 303, and the outer side is commonly fixed with an outer fixed seat 305.

[0075] A supporting angle slide 306 is fixedly installed in the main body of each set of inner fixed seats 303, and the supporting angle sliding sleeve 304 is slidably connected in the supporting angle slide 306 through an angle sliding column 307. An outer sleeve 308 is fixed to the outer end of each set of angle sliding columns 307, and a compression spring 309 is clamped between the outer side surface of the outer sleeve 308 and the inner side surface of the outer fixed seat 305;

[0076] The supporting corner sliding sleeve 304 can form a certain elastic sliding amount, eliminating the problem of unsmooth assembly with the corner clamping seat assembly 3 caused by the manufacturing tolerance of the cabinet 10;

[0077] Furthermore, the top of the inner facade of the supporting corner sliding sleeve 304 is provided with an outwardly inclined chamfer, so that each corner of the cabinet 10 can be more conveniently inserted into the supporting corner sliding sleeve 304 .

[0078] The specific structure of the double-position clamp seat assembly 4 and the bottom safety clamp seat assembly 5 is as follows: Figure 6 , Figure 7 and Figure 8 As shown, an inner rotating sleeve 403 is fixedly installed at the lower end of each group of inner columns 201, and the inner clamp seat 401 is rotatably connected in the inner rotating sleeve 403 through the inner rotating columns 404 on both sides of the bottom end, and the inner connecting arm 407 is fixedly connected to the outer end of the inner rotating column 404;

[0079] An outer rotating sleeve 405 is fixedly installed at the lower end of each group of short side seats 302, and the outer clamping seat 402 is rotatably connected in the outer rotating sleeve 405 through the outer rotating columns 406 on both sides of the bottom end.

The middle sliding seat 414 is slidably connected to the middle sliding sleeve 412 through the middle sliding column 413 at the bottom end. The bottom connecting plate 417 is fixedly connected to the bottom end of the middle sliding column 413.

[0081] A top spring 416 is sleeved and installed in each set of middle sliding columns 413. One side of the top spring 416 is fixed to the bottom end of the middle sliding seat 414, and the other side is fixed to the top end of the middle sliding sleeve 412.

[0082] Under the upward elastic force of the centering slide 414 formed by the top spring 416, when there is no external force pushing the center slide 414 downward, the center slide 414 is naturally in the upward limit position, that is, the outer clamping seat 402 and the inner clamping seat 401 are in the outward limit position, which can form a process of convenient downward insertion into the cabinet 10;

[0083] A clamping seat 418 is fixedly installed on the opposite side of the upper end of the outer clamping seat 402 and the inner clamping seat 401. The clamping seat 418 is made of rubber material and can clamp the side wall of the cabinet 10 while preventing the side wall of the cabinet 10 from being damaged.

[0084] The stand 501 is fixed to the middle of the bottom end of the bottom fixing plate 411. The bottom end body of each set of stand 501 is symmetrically fixed with a card sliding sleeve 502. The inclined seat 504 is slidably connected to the card sliding sleeve 502 through a card sliding column 503 on one side. The outer fixing plate 506 is fixedly connected to one end of the card sliding column 503, and the inclined seat 504 is fixedly connected to the other end of the card sliding column 503.

[0086] Under the action of the elastic supporting force formed by the locking spring 505, the inclined seat 504 can have an elastic force in the direction of the bottom connecting plate 417, and because the top end of the inclined seat 504 is an inclined surface, the inclined seat 504 can be pushed elastically outward during the downward movement of the bottom connecting plate 417, and after the bottom connecting plate 417 moves to the bottom of the inclined seat 504, the inclined seat 504 is elastically pushed out to form a snap connection with the downward position of the bottom connecting plate 417, so that the bottom connecting plate 417 is in a safe lower limit position, that is, the cabinet body 10 is safely clamped between the inner clamp seat 401 and the outer clamp seat 402.

[0087] The specific structure of the carriage member 6 is as follows: Fig. 9 As shown, the main slide rails 601 are laterally fixedly connected in pairs to the two outer upper ends of the base frame body 1, and the two sides of the bottom end of the main slide 602 are slidably connected to the main slide rails 601, which can push the main slide 602 so that the main slide 602 moves along the guide of the main slide rail 601, and a sliding drive mechanism can also be installed between the main slide 602 and the main slide rail 601 so that the main slide 602 automatically moves along the guide of the main slide rail 601.

[0088] The specific structure of the elastic release member 9 is as follows: Fig.16 and Fig.17As shown, the fixed plate slide column 902 is fixedly connected in a row in the top inner frame of the bottom frame body 1, and the corner fixed plate 901 is slidably connected to the fixed plate slide column 902. The sliding connection formed by the corner fixed plate 901 and the fixed plate slide column 902 can improve the stability of the movement of the corner fixed plate 901, so that the pushing effect of the corner fixed plate 901 formed by the pushing column 903 can accurately drive the movement of the outer fixed plate 506, and drive the inclined seat 504 to a position where it is disengaged from the bottom connecting plate 417.
