Description

Technical Field

[0001] The present invention relates to the field of processing machinery, and more specifically, to a parallel type drilling and milling machine. Background Art

[0002] The milling and drilling machine is one of the main equipment for machining. The method of machining a workpiece with a milling cutter on the milling and drilling machine is called milling. It can be used to machine planes, steps, inclined planes, grooves, formed surfaces, gears, and cutting, etc. In order to improve the drilling and milling efficiency, a parallel type drilling and milling machine was born. At present, due to the variety of profiles to be processed and their different shapes, it is necessary to frequently adjust the position of the drilling and milling cutter and the depth of drilling and milling according to the different profiles during the drilling and milling process. When a common drilling and milling machine is used for drilling and milling, the adjustment is difficult, and at the same time, the frequent adjustment also prolongs the working cycle and increases the cost; Chinese Patent with Publication No. CN101637869B discloses a drilling and milling machine, which realizes the drilling and milling of different profiles by adjusting the angle between the movable mounting plate and the fixed mounting plate installed on the machine head, so as to realize the adjustment of the drilling and milling positions of different profiles; Chinese Patent with Publication No. CN103753218A discloses a table panel drilling and milling machine, which uses a permanent magnet brushless motor and a vertical milling cutter as a mechanical cutting system, and a precision displacement table system that can be controlled in multiple ways, with simple operation, a man-machine interaction system suitable for milling cutter control, and at the same time uses a new type of fixture to ensure the safety of the panel and does not vibrate during processing; The above-mentioned method 1 can fixedly clamp different profiles, and method 2 can improve the clamping stability of the profiles. However, when clamping the profiles, two-sided clamping or four-sided clamping is usually adopted. The stability of two-sided clamping is poor, and when performing four-sided fixation, it needs to be completed in multiple steps, with cumbersome operation, which affects the efficiency of the drilling and milling operation. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a parallel type drilling and milling machine, which can quickly clamp and fix the drilling and milling profiles from four sides, improve the drilling and milling efficiency, and at the same time has stable clamping and ensures the drilling and milling quality.

[0004] To solve the above problems, the present invention adopts the following technical solutions.

[0005] A parallel type drilling and milling machine includes a bed body. A first slide rail is fixedly connected to the rear part of the upper end of the bed body, and a sliding seat is slidably connected to the upper end of the first slide rail. Both sides of the front end of the sliding seat are fixedly connected with lead screws, and a drilling and milling machine is jointly movably connected to the front ends between the two lead screws. A drilling and milling table is fixedly connected to the front part of the upper end of the bed body, and a second slide rail is fixedly connected to the upper end of the drilling and milling table; The upper end of the second slide rail is provided with a fixing mechanism, which can quickly and stably clamp and fix the profile to be processed. The fixing mechanism includes a fixing frame movably connected to the upper end of the second slide rail, and a support table is fixedly connected to the rear end inside the fixing frame.

[0006] Further, a first clamping block is fixedly connected to the rear part of the upper end of the support table, a hydraulic cylinder is fixedly connected to the front end inside the fixing frame, the output end of the hydraulic cylinder is fixedly connected to a second clamping block, a third slide rail is fixedly connected between the front end of the support table and the fixing frame, the second clamping block is slidably connected to the third slide rail, push rods are movably connected to both sides of the lower end of the second clamping block, rotating shafts are movably connected to both sides of the support table inside the fixing frame, third clamping blocks are fixedly connected to both sides of the rotating shaft outside the support table, and force-receiving blocks are fixedly connected to the lower ends of the third clamping blocks.

[0007] Further, an angle is formed between the third clamping block and the force-receiving block, and the inner side of the force-receiving block is an arc surface.

[0008] Further, an adjusting mechanism is provided inside the fixing frame. Sliding grooves are formed on both sides of the front and rear inner walls of the fixing frame at the positions of the support table, and sliders are slidably connected inside the sliding grooves. Both the front and rear ends of the rotating shaft penetrate through the inside of the slider. An extension block is fixedly connected to the front part of the push rod, and the extension block slidably penetrates through the inside of the second clamping block. A fixing pin is movably connected to the front end of the second clamping block, and the fixing pin penetrates into the inside of the second clamping block and presses against the extension block.

[0009] Further, a reinforcement mechanism is provided inside the third clamping block. The reinforcement mechanism includes a movable groove formed inside the third clamping block, and a elastic ring is movably connected inside the movable groove. Reinforcement blocks are movably embedded at both the front and rear ends of the third clamping block, and the reinforcement blocks are fixedly connected to the elastic ring.

[0010] Further, the elastic ring is in an Ω shape, and the elastic force of the elastic ring is greater than the moving resistance of the reinforcement block.

[0011] Further, a cleaning mechanism is provided at the bottom end inside the fixing frame. The cleaning mechanism includes support plates movably connected to both sides of the bottom end inside the fixing frame, hinges are movably connected between the support plates and the side walls of the fixing frame, lifting rods are fixedly connected between the upper ends of the support plates and the force-receiving blocks, and torsion springs are fixedly connected between the rotating shafts and the sliders.

[0012] Further, the elastic force of the torsion spring is greater than the resistance when the rotating shaft rotates.

[0013] Further, the displacement of the sliding seat and the first slide rail, the fixing frame and the second slide rail, and the drilling and milling machine and the lead screw are all controlled by stepping motors.

[0014] Further, a milling cutter is movably connected to the center of the lower end of the drilling and milling machine, and a flushing pipe is movably connected to the right side of the lower end of the drilling and milling machine.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this solution, during the movement of the push rod, it contacts the force-receiving block. Since the surface of the force-receiving block close to the support table is an arc surface, as the push rod continues to displace, the force-receiving block will be pushed to both sides of the support table, causing the third clamping block to form a lever movement using the rotating shaft. Then, the third clamping block clamps the profile from both sides. The entire clamping and fixing step is simple and has a wide range, improving the fixing quality of the profile, and the debris generated by drilling and milling falls inside the fixing frame, facilitating later cleaning.

[0016] (2) In this solution, the distance between the two third clamping blocks is adjusted by sliding the slider inside the chute. Then, the fixing pin is loosened, and the extension block is pushed slightly into the second clamping block. Next, the push rod and the second clamping block are fixed through the fixing pin. At this time, the push rod at the lower end of the second clamping block can contact the force-receiving block earlier due to the increased height. Thus, when fixing, the distance between the third clamping blocks also increases. By increasing the distance between the first clamping block and the second clamping block, profiles with larger sizes can be fixed, improving the applicable range of the fixing mechanism.

[0017] (3) In this solution, the impact force during clamping is buffered by the action of the elastic ring deformation, thereby reducing the damage caused by the third clamping block to the profile. When the third clamping block clamps the profile, the elastic ring is pressed into the movable groove, ensuring that the fixing process is not unstable due to the influence of the elastic ring.

[0018] (4) In this solution, the reinforcement mechanism is used to increase the size of the third clamping block, making the fixing of the profile more stable. After the elastic ring is pressed into the movable groove, the arc-shaped elastic ring is pressed into an approximately flat shape. At this time, the elastic ring unfolds and pushes the reinforcement block to extend outside the third clamping block, causing the extended reinforcement block to fit the surface of the profile. The elastic force of the elastic ring is used to push the reinforcement block to clamp the profile, thereby increasing the fixing area of the profile in combination with the third clamping block, and further improving the stability of the profile fixing.

[0019] (5) In this solution, the third clamping block drives the force-receiving block to approach the support table. At this time, the force-receiving block pulls the support plate using the lifting rod. The support plate rotates through the hinge with the fixing frame, causing the side of the support plate close to the support table to be lifted, thus making the support plate form an inclined surface. As a result, the debris on the support plate slides to both sides of the fixing frame, facilitating the later cleaning of the debris. At the same time, the cleanliness of the middle part of the fixing frame is ensured, and the fixing mechanism is not affected by the debris. Description of the Drawings

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 4, A parallel drill - milling machine, including a machine body 1. First, fix the profile to be processed on the fixing mechanism 10 at the front part above the machine body 1. Then, the fixing mechanism 10 displaces through the second slide rail 9 fixedly connected to the upper end of the drill - milling table 8 at the front part of the upper end of the machine body 1, and the slide block 3 moves on the first slide rail 2 so that the drill - milling machine 5 movably connected to the front end of the slide block 3 moves to directly above the processed profile. Then, the drill - milling machine 5 moves up and down by using the lead screws 4 fixedly connected to both sides of the front end of the slide block 3, and uses the drill - milling cutter 6 movably connected to the middle part of the lower end of the drill - milling machine 5 to perform drill - milling processing on the profile. During processing, the flushing pipe 7 movably connected to the right side of the lower end of the drill - milling machine 5 flushes the processing area to prevent the chips generated during processing from adhering to the surface of the profile and affecting the processing. It should be noted that the movements of the slide block 3 and the drill - milling machine 5 are both driven by stepper motors, and this part is prior art, so it will not be elaborated here; When fixing the profile, first place the profile into the fixing frame 101 movably connected to the upper end of the second slide rail 9, and place the profile on the support table 102 fixedly connected to the rear end inside the fixing frame 101. Then, use the hydraulic cylinder 104 fixedly connected to the front end inside the fixing frame 101 to push the second clamping block 105 fixedly connected to its front end to move backward along the third slide rail 106 between the front end of the support table 102 and the fixing frame 101 until the second clamping block 105 cooperates with the first clamping block 103 fixedly connected to the rear part of the upper end of the support table 102 to clamp the profile. And during the displacement of the second clamping block 105, the push rod 107 movably connected to its bottom moves backward synchronously. During the movement, the push rod 107 contacts the force - receiving block 1010 fixedly connected to the bottom of the third clamping block 109 on both sides of the support table 102. Since the surface of the force - receiving block 1010 close to the support table 102 is an arc surface, as the push rod 107 continues to displace, it will push the force - receiving block 1010 towards both sides of the support table 102, causing the third clamping block 109 to form a lever movement by using the rotating shafts 108 located on both sides of the support table 102 inside the fixing frame 101. Then, the third clamping block 109 clamps the profile from both sides. The entire clamping and fixing step is simple and has a wide range, improving the fixing quality of the profile, and the chips generated by drill - milling fall inside the fixing frame 101, which is convenient for later cleaning.

[0024] As Figure 4 shown in Figure 5 , since there are many types of profiles and their sizes are different, it is necessary to adjust the fixing mechanism 10 to ensure that profiles of different shapes can be fixed; During operation, the spacing between the third clamping blocks 109 and the length of the push rod 107 extending out of the second clamping block 105 can be adjusted by the adjustment mechanism 11. First, the slider 112 slidably connected to the inner groove 111 at the front and rear ends of the fixed frame 101 is used to slide in the groove 111 to adjust the spacing between the two third clamping blocks 109. Then, the fixing pin 114 movably connected to the front end of the second clamping block 105 is loosened to extend the extension block 113 fixedly connected to the front end of the push rod 107 toward the second clamping block. 105 is pushed in slightly, and then the push rod 107 and the second clamping block 105 are fixed by the fixing pin 114. At this time, the push rod 107 at the lower end of the second clamping block 105 can contact the force-bearing block 1010 earlier due to its increased height, so that when fixing, the distance between the third clamping blocks 109 is also increased. By increasing the distance between the first clamping block 103 and the second clamping block 105, larger profiles can be fixed, thereby improving the applicability of the fixing mechanism 10.

[0025] like Figure 4 and Figure 6 As shown, since the fixing mechanism 10 may cause certain damage to the profile due to the impact force when clamping and fixing the profile, it is necessary to perform certain buffering during clamping, and since the volumes of the first clamping block 103, the second clamping block 105 and the third clamping block 109 remain unchanged, when clamping and fixing a larger profile, uneven force may occur, resulting in unstable fixation; Therefore, when the third clamping block 109 moves toward the profile, the Ω-shaped elastic ring 121 movably connected inside it will first contact the surface of the profile. Under the action of the impact force, the elastic ring 121 is squeezed by the profile and the third clamping block 109 and deformed and shrinks to the inside of the movable groove 122 opened on the inner side of the third clamping block 109. The deformation of the elastic ring 121 is used to buffer the impact force of clamping, thereby reducing the damage to the profile caused by the third clamping block 109. When the third clamping block 109 clamps the profile, the elastic ring 121 is pressed into the movable groove 122, so that the fixing process will not be unstable due to the influence of the elastic ring 121.

[0026] In addition, the third clamping block 109 is added in conjunction with the reinforcement mechanism 12, so that the fixation of the profile is more stable. When the elastic ring 121 is pressed into the movable groove 122, the arc-shaped elastic ring 121 is pressed into a plane. At this time, the elastic ring 121 unfolds and pushes the reinforcement block 123 movably connected to the front and rear parts of the third clamping block 109 to extend out of the third clamping block 109, so that the extended reinforcement block 123 fits the surface of the profile, and uses the elastic force of the elastic ring 121 to push the reinforcement block 123 to clamp the profile, thereby increasing the fixing area of ​​the profile in combination with the third clamping block 109, thereby improving the stability of the profile fixation.

[0027] As Figure 3 , Figure 7 and Figure 8 shown, when fixing the profile, the third clamping block 109 drives the rotating shaft 108 to rotate and approach the profile. At this time, the torsion spring 134 fixedly connected between the rotating shaft 108 and the slider 112 contracts and deforms. After the drilling and milling are completed, the fixing of the profile is released, and the cleaning mechanism 13 provided inside the fixing frame 101 can be used to clean the debris inside the fixing frame 101. At this time, the torsion spring 134 resets and drives the third clamping block 109 to rotate back through the rotating shaft 108, so that the third clamping block 109 drives the force receiving block 1010 to approach the support table 102. At this time, the force receiving block 1010 pulls the support plate 131 movably connected to the bottom end inside the fixing frame 101 by the lifting rod 133 fixedly connected to its lower end. The support plate 131 rotates through the hinge 132 movably connected to the fixing frame 101, so that the side of the support plate 131 close to the support table 102 is lifted, so that the support plate 131 forms an inclined surface, and then the debris on the support plate 131 slides to both sides of the fixing frame 101, which is convenient for cleaning the debris later, and at the same time ensures the cleanliness of the middle part of the fixing frame 101, and the fixing mechanism 10 is not affected by the debris.

[0028] Usage method: First, fix the profile to be processed on the fixing mechanism 10, then the fixing mechanism 10 is displaced through the second slide rail 9, and the drilling and milling machine 5 is moved to directly above the processed profile by moving the sliding seat 3 on the first slide rail 2. Then, the drilling and milling machine 5 moves up and down by using the lead screw 4, and the profile is drilled and milled by using the drill bit 6. During the processing, the processing area is flushed by using the flushing pipe 7 to prevent the debris generated during the processing from adhering to the surface of the profile and affecting the processing; When fixing the profile, first place the profile on the support table 102, and then use the hydraulic cylinder 104 to push the second clamping block 105 to move backward along the third slide rail 106 until the second clamping block 105 cooperates with the first clamping block 103 to clamp the profile. And during the displacement of the second clamping block 105, the push rod 107 moves backward synchronously. During the movement, the push rod 107 contacts the force receiving block 1010. Since the surface of the force receiving block 1010 close to the support table 102 is an arc surface, as the push rod 107 continues to displace, the force receiving block 1010 will be pushed to both sides of the support table 102, so that the third clamping block 109 forms a lever movement by using the rotating shaft 108, and then the third clamping block 109 clamps the profile from both sides. The whole clamping and fixing step is simple and has a wide range, improving the fixing quality of the profile, and the debris generated by drilling and milling falls inside the fixing frame 101, which is convenient for later cleaning; The distance between the two third clamping blocks 109 is adjusted by sliding the slider 112 inside the sliding groove 111. Then, the fixing pin 114 is loosened, and the extension block 113 is slightly pushed into the second clamping block 105. Next, the push rod 107 and the second clamping block 105 are fixed through the fixing pin 114. At this time, the push rod 107 at the lower end of the second clamping block 105 can contact the force receiving block 1010 earlier due to the increased height. Therefore, when fixed, the distance between the third clamping blocks 109 is also increased. By increasing the distance between the first clamping block 103 and the second clamping block 105, larger profiles can be fixed, improving the applicable range of the fixing mechanism 10.

[0029] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
