Description

Technical Field

[0001] This application relates to the field of CNC machine tools, and in particular to a feeding mechanism for CNC machine tools. Background Technology

[0002] The common rail fuel system, commonly known as the high-pressure common rail direct injection system, is an advanced fuel injection technology widely used in modern diesel engines. The processing of the common rail fuel system involves purchasing blanks of the corresponding shape and machining various hole structures and thread structures on the blanks. The blanks are cylindrical and have evenly distributed protrusions on their top edges.

[0003] When processing the blank, it is necessary to drill a hole in the center of the blank. When drilling the blank, a clamping device is generally used to clamp the blank, and then a drilling device is used to drill from one end of the blank to the other end. Then the blank with the hole is removed from the clamping device, and a new blank is placed on top for drilling.

[0004] In order to improve the efficiency of drilling the blanks, multiple drilling devices are installed on the drilling table to drill the blanks. When placing the blanks, the workers place the blanks one by one at the drilling position and then start drilling. The workers place the blanks one by one before starting to drill, which results in low efficiency when loading the blanks. Utility Model Content

[0005] The purpose of this application is to solve the problem mentioned in the background art that when placing blanks, workers have to place the blanks one by one into the drilling position before starting to drill, which leads to low efficiency in feeding. This application provides a feeding mechanism for CNC machine tools.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A feeding mechanism for a CNC machine tool includes a drilling platform, an electric slide rail fixed on the drilling platform, a clamping block slidably connected to the electric slide rail, a plurality of clamping heads (first type) fixed on the clamping block, a plurality of clamping heads (second type) corresponding to the clamping heads (first type) fixed on the drilling platform, a drilling device provided on the side of the clamping block away from the clamping heads (first type), the drilling device being mounted on the drilling platform, a support platform provided between the clamping heads (first type) and the clamping heads (second type), the support platform being fixedly connected to the drilling platform, a feeding mechanism provided on the support platform, and a sensing mechanism provided on one side of the support platform.

[0008] By adopting the above technical solution, several blanks corresponding to the number of clamping heads are placed on the feeding mechanism of the support platform. Then, the feeding mechanism moves several blanks between clamping heads one and clamping heads two. The clamping block moves on the electric slide rail, causing the clamping block to move clamping heads one closer to clamping heads two, so that clamping heads one and clamping heads two clamp the two ends of the blanks. Then, the cutting head of the drilling device passes through the clamping block and clamping heads one, allowing the drilling device to drill holes in the blanks. This facilitates the feeding and unloading of blanks when drilling with the drilling device, and improves the efficiency of feeding and unloading.

[0009] Furthermore, the feeding mechanism includes a feeding platform mounted on a support platform, a plurality of feeding support frames fixed on the feeding platform, a lifting component mounted on the feeding platform, and a translation component mounted on the support platform.

[0010] By adopting the above technical solution, the lifting and translation components are used to move the feeding platform. When the feeding platform moves several feeding support frames, the feeding support frames move the blanks, thus facilitating the simultaneous feeding and unloading of several blanks, improving the efficiency of blank punching, feeding, and unloading.

[0011] Furthermore, the lifting assembly includes a lifting seat fixed to the bottom of the feeding platform, a lifting inclined block is provided at the bottom of the lifting seat, the lifting seat abuts against the inclined surface of the lifting inclined block, and two symmetrical lifting slide rails are fixed at the bottom of the lifting seat, and the lifting seat is slidably connected to the lifting inclined block by means of the lifting slide rails.

[0012] By adopting the above technical solution, the lifting seat slides on the inclined surface of the lifting block under the restriction of the lifting slide rail, thereby making it convenient for the lifting seat to drive the feeding platform to lift.

[0013] Furthermore, a lifting motor is fixed on the lifting inclined block, a lifting threaded rod is fixed at the output end of the lifting motor, a lifting slider is threadedly connected to the lifting threaded rod, the lifting slider is slidably connected to the lifting inclined block, and the lifting slider is fixedly connected to the lifting seat.

[0014] By adopting the above technical solution, the lifting screw rod drives the lifting slider to move along the inclined surface of the lifting block, thereby facilitating the movement of the lifting seat on the lifting block.

[0015] Furthermore, the translation component includes a translation slide rail fixed to the support platform, a translation motor fixed to one end of the translation slide rail, a translation threaded rod fixed to the output end of the translation motor, a translation slider threadedly connected to the translation threaded rod, the translation slider being slidably connected to the translation slide rail, and the translation slider being fixedly connected to the lifting inclined block.

[0016] By adopting the above technical solution, the translation threaded rod drives the translation slider, and when the translation slider moves on the translation slide rail, it drives the lifting inclined block, thereby making it easy for the feeding platform to move on the support platform.

[0017] Furthermore, identification tapes are affixed to several of the aforementioned feeding support frames.

[0018] By adopting the above technical solution, identification tapes are affixed to several feeding support frames. The identification tapes are divided into blue and red, and are distributed alternately, which makes it convenient for workers to place them and reduces the possibility of workers placing them incorrectly.

[0019] Furthermore, the sensing mechanism includes a support rod fixed to one side of the support platform, a sensing support frame fixed on the support rod, and a plurality of sensing heads fixed on the sensing support frame. The sensing heads pass through the sensing support frame, and the plurality of sensing heads correspond to the feeding support frame.

[0020] By adopting the above technical solution, the sensor head on the induction support frame can identify whether a blank is placed. When an un-drilled blank is placed on the feeding support frame, the sensor head will issue a reminder, thereby further reducing the possibility of workers placing the blank incorrectly.

[0021] Furthermore, a limit frame is fixed on one side of the drilling platform, and the limit frame is located above the support platform.

[0022] By adopting the above technical solution, the height of the feeding platform is lower than that of the limit frame, so that the feeding platform will not collide with clamping head one and clamping head two when it moves.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, by making the feeding support frame fixed on the feeding platform twice the size of the combination of clamping head one and clamping head two, when it is necessary to feed the blank between several clamping heads one and two, firstly, several blanks corresponding to the number of support heads one and two are placed on the feeding support frame. When placing them, there is an empty feeding support frame between two adjacent blanks. The feeding support frame has arcs at both ends to allow the blanks to be placed stably on the feeding support frame. Then, the translation motor drives the translation threaded rod, which drives the translation slider to slide on the translation slide rail, allowing the lifting inclined block to move the lifting seat and the feeding platform. Then, the lifting motor drives the lifting threaded rod, which drives the lifting slider to move the lifting seat on the inclined surface of the lifting inclined block. Then, the lifting seat drives the feeding platform to rise, so that the blanks on the feeding support frame are aligned with the corresponding clamping heads one and two. Then the clamping heads... The first and second clamping heads punch holes in the blanks. While punching the blanks, the feeding platform resets, and the worker places unpunished blanks on top. An empty feeding support frame remains between adjacent blanks. When the feeding platform moves back between the first and second clamping heads, the lifting and translation motors adjust the platform's position so that the empty feeding support frame faces the punched blank. The empty feeding support frame receives the punched blank. Then, the lifting and translation motors adjust the platform's position again, sending unpunished blanks between the first and second clamping heads for punching. The feeding platform then resets with the punched blanks, and the worker removes the punched blanks and places new blanks for punching. This process allows for convenient feeding and unloading of multiple blanks simultaneously, improving the efficiency of punching, feeding, and unloading.

[0025] 2. In this application, when an un-drilled blank is placed on the feeding support frame, a sensor head on the support frame identifies whether a blank has been placed. When an un-drilled blank is placed on the feeding support frame, the sensor head issues a reminder. The sensor head is a laser sensor head. When the worker places the blank incorrectly, the sensor head issues a corresponding reminder. At the same time, the sensor head can be used to determine whether the blank is placed correctly. Then, when feeding the blank between clamping head one and clamping head two, the height of the feeding platform must be lower than the limit frame, so that the feeding platform will not hit clamping head one and clamping head two when it moves, thereby further reducing the possibility of incorrect placement of the blank on the feeding support frame.

[0031] The following is in conjunction with the appendix Figure 1 —3 provides further detailed description of this application.

[0032] This application discloses a feeding mechanism for CNC machine tools.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A feeding mechanism for a CNC machine tool includes a drilling platform 1, an electric slide rail 2 fixed on the drilling platform 1, a clamping block 3 slidably connected to the electric slide rail 2, a plurality of clamping heads 4 fixed on the clamping block 3, a plurality of clamping heads 5 corresponding to the clamping heads 4 fixed on the drilling platform 1, a drilling device 6 provided on the side of the clamping block 3 away from the clamping heads 4, the drilling device 6 being mounted on the drilling platform 1, a support platform 9 provided between the clamping heads 4 and the clamping heads 5, the support platform 9 being fixedly connected to the drilling platform 1, a feeding mechanism 7 provided on the support platform 9, and a sensing mechanism 8 provided on one side of the support platform 9.

[0034] When drilling holes in cylindrical blanks, firstly, with the assistance of the sensing mechanism 8, several blanks corresponding to the number of clamping heads 4 are placed on the feeding mechanism 7 on the support platform 9. Then, the feeding mechanism 7 moves several blanks between clamping heads 4 and clamping heads 5. Next, the clamping block 3 moves on the electric slide rail 2, causing the clamping head 4 to move closer to the clamping head 5, so that the clamping heads 4 and 5 clamp both ends of the blank. Then, the cutting head of the drilling device 6 passes through the clamping block 3 and clamping head 4, allowing the drilling device 6 to drill holes in the blank. At the same time, the feeding mechanism 7 resets, and the worker places the blank. When the next blank is placed, the feeding mechanism 7 sends the blank between the clamping head 4 and the clamping head 5. The blank that has been drilled first falls onto the feeding mechanism 7. Then the feeding mechanism 7 clamps the unprocessed blank facing the clamping head 4 and the clamping head 5, and then continues drilling. The feeding mechanism 7 then sends out the blank with the hole. Then the worker takes off the blank with the hole and puts in a new blank. By using the feeding mechanism 7 to transfer several blanks at once for drilling when drilling blanks, the feeding and unloading of blanks is facilitated when drilling with the drilling device 6, thus improving the efficiency of feeding and unloading.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The feeding mechanism 7 includes a feeding platform 71 set on the support platform 9, a plurality of feeding support frames 72 fixed on the feeding platform 71, a lifting component 73 set on the feeding platform 71, and a translation component 74 set on the support platform 9.

[0036] In addition, the lifting assembly 73 includes a lifting seat 731 fixed to the bottom of the feeding platform 71. A lifting inclined block 732 is provided at the bottom of the lifting seat 731. The inclined surfaces of the lifting seat 731 and the lifting inclined block 732 abut against each other. Two symmetrical lifting slide rails 733 are fixed at the bottom of the lifting seat 731. The lifting seat is slidably connected to the lifting inclined block 732 by means of the lifting slide rails 733.

[0037] Furthermore, a lifting motor 734 is fixed on the lifting inclined block 732, and a lifting threaded rod 735 is fixed on the output end of the lifting motor 734. A lifting slider 736 is threadedly connected to the lifting threaded rod 735. The lifting slider 736 is slidably connected to the lifting inclined block 732, and the lifting slider 736 is fixedly connected to the lifting seat 731.

[0038] Furthermore, the translation component 74 includes a translation slide rail 741 fixed on the support platform 9. One end of the translation slide rail 741 is fixed with a translation motor 743. The output end of the translation motor 743 is fixed with a translation threaded rod 744. A translation slider 742 is threadedly connected to the translation threaded rod 744. The translation slider 742 is slidably connected to the translation slide rail 741. The translation slider 742 is fixedly connected to the lifting inclined block 732.

[0039] The feeding support frame 72, fixed on the feeding platform 71, is twice the size of the combination of clamping head 4 and clamping head 5. When it is necessary to feed the blank between several clamping heads 4 and 5, several blanks corresponding to the number of support heads 1 and 2 are first placed on the feeding support frame 72. When placing them, there is an empty feeding support frame 72 between two adjacent blanks. The feeding support frame 72 has arcs at both ends to stably place the blanks on it. Then, the translation motor 743 drives the translation threaded rod 74. 4. The translation threaded rod 744 drives the translation slider 742 to slide on the translation rail 741, causing the lifting inclined block 732 to move the lifting seat 731 and the feeding platform 71. Then, the lifting motor 734 drives the lifting threaded rod 735, causing the lifting slider 736 to drive the lifting seat 731 to slide on the inclined surface of the lifting inclined block 732. Then, the lifting seat 731 drives the feeding platform 71 to rise, so that the blank on the feeding support frame 72 is aligned with the corresponding clamping head 4 and clamping head 5. Then, the clamping head 4 and clamping head 5 press the blank. When drilling holes in the blank, the feeding platform 71 resets, and then the worker places the un-drilled blank back on, with an empty feeding support 72 still separating adjacent blanks. When the feeding platform 71 moves again between clamping heads 4 and 5, the position of the feeding platform 71 is adjusted using the lifting motor 734 and the translation motor 743, so that the empty feeding support 72 faces the blank that has been drilled. The empty feeding support 72 receives the drilled blank, and then the lifting motor 734 and translation motor 743 are used again to adjust the position of the feeding platform 71. Motor 743 adjusts the position of feeding platform 71, allowing un-drilled blanks to be sent between clamping head 4 and clamping head 5 for drilling. Then, feeding platform 71 returns to its original position with the drilled blanks. The worker removes the drilled blanks and places new blanks on top for drilling. By moving and lifting feeding platform 71 on support platform 9, and using feeding support frame 72 on feeding platform 71 to feed and unload blanks, it is possible to feed and unload several blanks together, improving the efficiency of blank drilling, feeding, and unloading.

[0040] Reference Figure 1 , Figure 2 and Figure 3Each of the feeding support frames 72 has an identification tape 75 affixed to it. The identification tapes 75 are divided into blue and red, and are distributed alternately. When feeding, the un-drilled blank is placed on the feeding support frame 72 with the red identification tape 75, and when unloading, the blank with the holes is placed on the blue identification tape 75. By affixing different identification tapes 75 to the feeding support frames 72, the purpose of the feeding support frames 72 can be distinguished, which makes it easier for workers to place them and reduces the possibility of workers placing them incorrectly.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The sensing mechanism 8 includes a support rod 81 fixed to one side of the support platform 9. A sensing support frame 82 is fixed on the support rod 81. Several sensing heads 83 are fixed on the sensing support frame 82. The sensing heads 83 pass through the sensing support frame 82. The several sensing heads 83 correspond to the feeding support frame 72.

[0042] In addition, a limit frame 84 is fixed on one side of the drilling platform 1, and the limit frame 84 is located above the support platform 9.

[0043] When an un-drilled blank is placed on the feeding support frame 72, the sensor head 83 on the sensor support frame 82 identifies whether a blank has been placed. When an un-drilled blank is placed on the feeding support frame 72, the sensor head 83 issues a reminder. The sensor head 83 is a laser sensor head 83. When the worker places the blank incorrectly, the sensor head 83 issues a corresponding reminder. At the same time, the sensor head 83 can be used to know whether the blank is placed correctly. Then, when feeding the blank between the clamping head 4 and the clamping head 5, the height of the feeding platform 71 must be lower than the limit frame 84 so that the feeding platform 71 will not hit the clamping head 4 and the clamping head 5 when it moves. By using the sensor head 83 on the sensor support frame 82 to identify the blank on the feeding support frame 72, the possibility of incorrect placement of the blank on the feeding support frame 72 can be further reduced.

[0044] Working principle: When drilling holes in a cylindrical blank, first align the sensor head 83 on the induction support frame 82 with the feeding support frame 72. Then, according to the markings 75 on the feeding support frame 72, place several blanks corresponding to the number of support heads one and two onto the feeding support frame 72. When placing the blanks, leave an empty feeding support frame 72 between adjacent blanks. The feeding support frame 72 has rounded ends to ensure the blanks are stably placed on it. Simultaneously, the sensor head 83 identifies the blank material on the feeding support frame 72 to determine if the blank material is misplaced. Then, the translation motor 743 drives the translation threaded rod 744, which in turn drives the translation slider 742 to slide on the translation rail 741. This causes the lifting inclined block 732 to move the lifting seat 731 and the feeding platform 71. Then, the lifting motor 734 drives the lifting threaded rod 735, which in turn drives the lifting slider 736 to move the lifting seat 731 on the inclined surface of the lifting inclined block 732. The lowering seat 731 raises the feeding platform 71, aligning the blanks on the feeding support frame 72 with the corresponding clamping heads 4 and 5. The clamping heads 4 and 5 then drill holes in the blanks. While drilling, the feeding platform 71 resets, and the worker places un-drilled blanks on top, maintaining an empty feeding support frame 72 between adjacent blanks. When the feeding platform 71 moves again between the clamping heads 4 and 5, the lifting motor 734 and... The translation motor 743 adjusts the position of the feeding platform 71 so that the empty feeding support frame 72 faces the blank that has been opened. The empty feeding support frame 72 receives the blank that has been opened. Then, the lifting motor 734 and the translation motor 743 are used again to adjust the position of the feeding platform 71 so that the blank that has not been punched is sent between the clamping head 4 and the clamping head 5 for punching. Then the feeding platform 71 returns to its original position with the punched blank. The worker removes the blank with the opened hole and then puts on a new blank to prepare for punching.
