Description

Technical Field

[0001] This utility model relates to the field of radiator profile processing technology, specifically to an integrated device for drilling and tapping radiators. Background Technology

[0002] Electronic products (such as computer motherboards and graphics cards) generate heat during use, which can negatively impact product performance. Therefore, heat sinks are necessary to dissipate heat in these electronic products. The heat sinks typically consist of a base and several heat sink fins arranged in an array on the base. Figure 1 As shown, a heat sink 1 is provided, including a base 11 and a plurality of heat dissipation fins 12 arranged on the bottom surface of the base 11, with a cavity 14 formed between adjacent heat dissipation fins 12, and a side extension 13 extending to one side of the side wall of the base 11.

[0003] To facilitate the installation and fixing of the aforementioned radiators, additional holes need to be added to the radiators for fixing or installation. Therefore, drilling and / or tapping are required on the radiator fins, such as drilling and tapping on the top surface of the base. Traditionally, drilling and tapping of radiators involves first drilling with a drilling machine and then transferring the radiator to a tapping machine for tapping, which results in unsatisfactory processing efficiency. Furthermore, the loading and unloading of radiators is still done manually, with low automation, leading to low production efficiency. In addition, when operators place or remove workpieces, their hands must pass under the head of the drilling machine and / or tapping machine, posing a safety hazard if the switch malfunctions or the operation is improper. Summary of the Invention

[0004] The purpose of this utility model is to provide an integrated radiator drilling and tapping device with a high degree of automation, which can combine drilling and tapping processes into one machine and realize automatic loading and unloading, thereby improving production efficiency and solving the problem of low production efficiency of existing radiator drilling and tapping mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An integrated radiator drilling and tapping device is used to automatically load, drill, tap, and unload radiators. It includes a machine base with a turntable rotatably mounted on its top. The turntable has loading, drilling, tapping, and unloading stations arranged at equal intervals along its axis. Each loading, drilling, tapping, and unloading station is equipped with a first fixture for placing the radiator. A loading conveyor belt is located on one side of the loading station, and an unloading conveyor belt is located on the other side of the machine base. A transfer mechanism for moving radiators from the loading conveyor belt to the loading station is located beside the loading conveyor belt. The feeding mechanism includes a drilling station equipped with a drilling mechanism for drilling holes in the radiator, a tapping station equipped with a tapping mechanism for tapping the radiator, and an unloading station equipped with an unloading mechanism for transferring the radiator processed at the unloading station to the unloading conveyor belt. The first fixture includes a fixture body, the top wall of which has a first part-taking groove and a second part-taking groove in a cross shape. The two side walls of the first part-taking groove are respectively provided with a first limiting groove extending to the top wall of the fixture body. One side wall of the first limiting groove has a second limiting groove extending to the top wall of the fixture body.

[0007] Preferably, the unloading mechanism includes a support arm, a hanging plate, a slide, a lateral drive assembly, a vertical drive assembly, and a clamp. The support arm is erected on the outside of the unloading conveyor belt. One end of the hanging plate is vertically connected to the top of the support arm, and the other end extends above the turntable. The slide is movably mounted on the side wall of the hanging plate along its extension direction. The lateral drive assembly is connected to the slide, and the vertical drive assembly is located on the side wall of the slide and is used to drive the clamp to lift and lower.

[0008] Preferably, the transverse drive assembly includes a bearing housing, a screw, a servo motor, and a nut sleeve. The two bearing housings are disposed opposite to each other on the side wall of the mounting plate. The screw is rotatably mounted on the two bearing housings. The servo motor is mounted on one end of the mounting plate. The output shaft of the servo motor is connected to one end of the screw.

[0010] Preferably, the clamp includes a mounting plate, a clamping plate, and a support plate. The mounting plate is fixed on the connecting plate. One end of the clamping plate is perpendicularly connected to one end of the mounting plate. One end of the support plate is perpendicularly connected to the end of the clamping plate away from the mounting plate. The mounting plate and the support plate are arranged vertically opposite each other. The mounting plate, the clamping plate, and the support plate form a clamping groove for holding the radiator.

[0011] Preferably, the clamping plate has a plurality of equally spaced clearance grooves, which extend axially to the end face of the support plate.

[0012] Preferably, the end of the tray away from the clamp is provided with several protrusions to prevent the radiator from falling off the clamp.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the heat sink is loaded through the feeding mechanism, then the heat sink is drilled through the drilling mechanism, then the heat sink is tapped through the tapping mechanism, and finally the heat sink is unloaded through the unloading mechanism.

[0018] Please see Figure 1-6An integrated drilling and tapping device for radiators is disclosed, used for automatically loading, drilling, tapping, and unloading radiators 1. The device includes a machine base 2, with a turntable 3 rotatably mounted on its top. The turntable 3 has loading stations 31, drilling stations 32, tapping stations 33, and unloading stations 34 arranged at equal intervals along its axis of rotation. A loading conveyor belt 4 is located on one side of the loading station 31, and an unloading conveyor belt 5 is located on one side of the unloading station 34. A loading mechanism (not shown) is located beside the loading conveyor belt 4 for transferring the radiators 1 from the loading conveyor belt 4 to the loading station 31.

The unloading station 34 is equipped with an unloading mechanism 8 for transferring the radiators 1 processed at the unloading station 34 to the unloading conveyor belt 5. In this embodiment, the feeding direction of the feeding conveyor belt 4 is perpendicular to the feeding direction of the unloading conveyor belt 5; the turntable 3 is driven to rotate by a rotary motor located below the machine base 2.

[0019] This utility model first loads the radiator 1 through a feeding mechanism, then drills holes in the radiator 1 through a drilling mechanism 6, then taps the radiator 1 through a tapping mechanism 7, and finally unloads the radiator 1 through an unloading mechanism 8. The loading, drilling, tapping and unloading are carried out simultaneously without manual assistance, resulting in a high degree of automation and high production efficiency. The absence of manual operation for picking up and placing parts not only reduces labor costs but also avoids production safety accidents, resulting in low safety hazards.

[0020] Please see Figure 3-4 The loading station 31, drilling station 32, tapping station 33, and unloading station 34 are all equipped with first fixtures 35 for placing radiators 1; the surface of the loading conveyor belt 4 is provided with several second fixtures 41 for placing radiators 1 at equal intervals along its length, and the surface of the unloading conveyor belt 5 is provided with several third fixtures 51 for placing radiators 1 at equal intervals along its length. In this embodiment, the machine base 2 is square, and a first frame and a second frame are respectively provided on both sides of one corner of the machine base 2. The loading conveyor belt 4 is provided on the top of the first frame, and the unloading conveyor belt 5 is provided on the top of the second frame. The loading conveyor belt 4 and the unloading conveyor belt 5 are both wound around their respective frames by conveyor rollers, and the conveyor rollers are driven to rotate by conveying motors respectively provided on the first frame and the second frame, thereby realizing the conveying of radiators 1 by the loading conveyor belt 4 and the unloading conveyor belt 5.

[0021] Please see Figure 2The first fixture 35 includes a fixture body. The top wall of the fixture body has a first part-retrieving groove 351 and a second part-retrieving groove 352 in a cross shape. The two side walls of the first part-retrieving groove 351 are respectively provided with a first limiting groove 353 extending to the top wall of the fixture body. The first limiting groove 353 is used to support and position the base 11 of the heat sink 1. One side wall of the first limiting groove 353 has a second limiting groove 354 extending to the top wall of the fixture body. The second limiting groove 354 is used to support and position the side extension 13 of the heat sink 1. The first part-retrieving groove 351 is provided to facilitate the loading and unloading mechanisms 8 to pick up and place parts. The second part-retrieving groove 352 is provided to facilitate the manual handling of the heat sink 1 and to facilitate product sampling inspection.

[0022] In this embodiment, the structure and function of the second fixture 41 and the third fixture 51 of the fixture body are the same as those of the first fixture 35. They are all for placing and positioning the radiator 1 workpiece, and their structure will not be described in detail here.

[0023] Please see Figure 3 The unloading mechanism 8 includes a support arm 81, a hanging plate 82, a slide block 83, a horizontal drive assembly 84, a vertical drive assembly 85, and a clamp 9. The support arm 81 is erected on the outside of the unloading conveyor belt 5. One end of the hanging plate 82 is vertically connected to the top of the support arm 81, and the other end extends above the turntable 3. The slide block 83 is movably mounted on the side wall of the hanging plate 82 along its extension direction. The horizontal drive assembly 84 is connected to the slide block 83, and the vertical drive assembly 85 is located on the side wall of the slide block 83 and is used to drive the clamp 9 to rise and fall. The side wall of the hanging plate 82 is covered with a guide rail, and the slide block 83 is movably mounted on the guide rail.

[0024] Please refer to Figure 4 The transverse drive assembly 84 includes a bearing housing 841, a screw 842, a servo motor 843, and a nut sleeve (not shown). The two bearing housings 841 are disposed opposite each other on the side wall of the mounting plate 82. The screw 842 is rotatably mounted on the two bearing housings 841. The servo motor 843 is mounted on one end of the mounting plate 82, and its output shaft is connected to one end of the screw 842 to drive the screw 842 to rotate. The nut sleeve is threaded onto the screw 842 and connected to the slide block 83. The vertical drive assembly 85 includes a first cylinder 851 mounted on the side wall of the slide block 83 and a connecting plate 852 connected to one end of the piston rod of the first cylinder 851. The clamp 9 is mounted on the connecting plate 852. The side wall of the mounting plate 82 is provided with a bellows-shaped protective cover that covers the screw 842 and the guide rail.

[0025] Please see Figure 3-4During unloading, the servo motor 843 drives the screw 842 to rotate. The screw 842, through the nut sleeve, drives the slide 83 and the vertical drive component 85 on the slide 83, along with the clamp 9, to move towards the outer edge of the turntable 3 until the clamp 9 holds the radiator 1 on the first fixture 35. Then, the first cylinder 851 drives the clamp 9 and the radiator 1 to rise, so that the radiator 1 is detached from the first fixture 35. Next, the servo motor 843 drives the screw 842 to reverse. The screw 842, through the nut sleeve, drives the slide 83 and the vertical drive component 85 on the slide 83, along with the clamp 9, to move laterally above the unloading conveyor belt 5. Subsequently, the first cylinder 851 drives the clamp 9 and the radiator 1 to descend until the radiator 1 is placed on the third fixture 51 of the unloading conveyor belt 5. The servo motor 843 continues to drive the screw 842 to reverse until the clamp 9 is detached from the radiator 1 on the third fixture 51. Finally, the first cylinder 851 drives the clamp 9 to rise, waiting for the next unloading action.

[0026] During each feeding operation, the feeding conveyor belt 5 is stationary. After the fixture 9 places the radiator 1 on the third fixture 51 at the rightmost end of the feeding conveyor belt 5, the feeding conveyor belt 5 moves forward (as shown in the image). Figure 3 (In the direction of the arrow) move one station so that the next empty third fixture 51 moves to the rightmost end of the unloading conveyor belt 5. By repeating this process, the radiator 1 can be conveyed forward in a cyclical manner.

[0027] Please see Figure 6 The clamp 9 includes a mounting plate 91, a clamping plate 92, and a support plate 93. The mounting plate 91 is fixed to the connecting plate 852. One end of the clamping plate 92 is perpendicularly connected to one end of the mounting plate 91. One end of the support plate 93 is perpendicularly connected to the end of the clamping plate 92 away from the mounting plate 91. The mounting plate 91 and the support plate 93 are arranged vertically opposite each other. The mounting plate 91, clamping plate 92, and support plate 93 form a clamping groove 94 for holding the radiator 1. The clamping plate 92 has several equally spaced clearance grooves 95. The clearance grooves 95 extend axially to the end face of the support plate 93. The clearance grooves 95 are provided so that the support plate 93 can extend into the clearance grooves. Figure 1 The heat sink 1 is placed in the cavity 14 so that the support plate 93 can lift the heat sink 1 upwards so that the clamp 9 can pick up and put down the heat sink 1.

[0028] The mounting plate 91 has at least two screw holes, through which bolts are passed to fix the mounting plate 91 to the connecting plate 852, making installation convenient and facilitating replacement and maintenance. The support plate 93 has several protrusions 96 at the end away from the clamping plate 92 to prevent the radiator 1 from falling off the clamp 9. In this embodiment, the feeding mechanism and the unloading mechanism 8 have the same structure, differing only in their arrangement direction; their specific structures and working principles will not be described in detail here.

[0029] Please see Figure 3 as well as Figure 5Both the drilling mechanism 6 and the tapping mechanism 7 are existing mature technologies. They are driven by the host to rotate the drill bit or tap, and extend and retract during the rotation to drill or tap the radiator 1. Their specific structure and working principle will not be described in detail here.

[0030] Please see Figure 3 The machine tool 2 is equipped with clamping mechanisms 10 at both the drilling station 32 and the tapping station 33. Each clamping mechanism 10 includes a second cylinder 101 mounted on the top surface of the machine tool 2 and a pressure plate 102 connected to the telescopic rod of the second cylinder 101. The pressure plate 102 extends horizontally above the first fixture 35. The pressure plate 102 has limiting holes penetrating its upper and lower surfaces. During drilling or tapping, the second cylinder 101 drives the pressure plate 102 to press the radiator 1 firmly onto the first fixture 35, facilitating the drilling mechanism 6 or the tapping mechanism 7 to pass through the limiting holes for drilling or tapping. In this embodiment, the machine tool 2 is equipped with a cylinder guard to protect the second cylinder 101.
