Description

Technical Field

[0001] This utility model relates to processing equipment, and in particular to a feeding and conveying device and a drilling and cutting machine. Background Technology

[0002] A heatsink is a device specifically designed to dissipate heat from heat-generating electronic components in electrical appliances. They are typically made of materials such as aluminum alloy, brass, or bronze, and come in various forms, including plate-shaped, sheet-shaped, and multi-sheet-shaped. For example, in computers, the central processing unit (CPU) requires a large heatsink to maintain stable operation; similarly, in televisions, critical components such as power transistors, horizontal output transistors, and power amplifier transistors in the amplifier also require heatsinks to maintain normal operation and extend their lifespan.

[0003] Existing heat sink transport mechanisms typically use conveyor belts. Since the ends of the numerous sheet-like structures on the heat sink are in direct contact with the conveyor belt, friction between the conveyor belt and the heat sink is likely to occur during transport, causing wear and tear on either the conveyor belt or the heat sink, which is detrimental to transport.

[0058] Reference Figures 1-7 The basic embodiment of the first aspect of this utility model provides a three-sided integrated drilling and tapping cutting device, comprising:

[0059] 100 racks;

[0060] The transport track 200 extends from the frame 100 in the left and right directions, and the transport track 200 is provided with a reference surface;

[0061] The first clamping mechanism 300 includes a first clamping component 310 and a second clamping component 320 on both sides of the transport track 200. The first clamping component 310 can be close to the transport track 200 and fixed on the reference surface, or the first clamping component 310 can be far away from the transport track 200. The second clamping component 320 can be close to or far away from the transport track 200.

[0062] Translation mechanism 400 is mounted on frame 100 and is used to drive first clamping mechanism 300 to move along transport track 200;

[0063] The processing mechanism includes a first processing component 510, a second processing component 520 and a third processing component 530. The first processing component 510 and the second processing component 520 are respectively disposed on both sides of the transport track 200, and the third processing component 530 is disposed above the transport track 200.

[0064] The cutting mechanism 600 is located at the exit of the transport track 200.

[0065] According to embodiments of this utility model, by such a configuration, at least the following effects can be achieved:

[0066] An uncut elongated workpiece is placed on the transport track 200, and the first clamping assembly 310 and the second clamping assembly 320 clamp both sides of the workpiece respectively, achieving a stable fixation of the workpiece on the first clamping mechanism 300. With the aid of the translation mechanism 400, the first clamping mechanism 300 can move as a whole along the transport track 200. During this process, the first, second, and third processing components 530 equipped on the processing architecture can simultaneously perform drilling operations on three sides of the workpiece, significantly improving work efficiency. The cutting mechanism 600, located at the end of the transport track 200, is responsible for dividing the elongated workpiece into individual workpieces. This design allows drilling and cutting operations to be performed simultaneously, thereby greatly improving production efficiency. The end face of the first clamping component 310 can approach the transport track 200 and move to the reference surface, which serves as a positioning reference to ensure that one side of the workpiece is accurately aligned with the reference surface after clamping. Subsequently, the second clamping component 320 moves toward the workpiece and works together with the first clamping component 310 to form a fixing force, so that the workpiece is firmly fixed on the transport track 200. This placement method based on the reference surface can ensure the positional accuracy of drilling on three sides, thereby improving the processing quality and ensuring the consistency and reliability of the product.

[0067] It is understandable that the reference surface is not an actual object, but a positioning reference based on the workpiece. During workpiece machining, one of the surfaces is the reference surface, and the reference is the zero point. As long as the position parameters of each hole relative to the reference surface are written into the controller, the machining mechanism can process the workpiece. During the machining of workpieces of different sizes, one surface is located on the reference surface, and the opposite surface is abutted by the second clamping component 320.

[0068] In some embodiments, the moving distance of the first clamping component 310 is less than the moving distance of the second clamping component 320.

[0069] In this configuration, the first clamping component 310 serves as a reference clamp with a small moving distance and high moving accuracy. After the first clamping component 310 moves, there is a small distance between the first clamping component 310 and the workpiece, which can prevent the first clamping component 310 from scratching the workpiece during translation. The second clamping component 320 has a larger moving distance, which can adapt to workpieces of different sizes. Large workpieces move a smaller distance, while small workpieces move a larger distance.

[0070] The first clamping mechanism 300 is located in the processing position. The processing process will generate a large amount of processing waste. If the length of the first clamping component 310 in the front-to-back direction is larger, it will be easier to accumulate processing waste. The first clamping component 310 is set with a smaller movement distance, which can reduce the overall length of the first clamping component 310 and reduce the accumulation of processing waste.

[0071] In some embodiments, the first clamping component 310 includes:

[0072] First support 311;

[0073] The first gripper 312 is slidably disposed on the first support 311 in the front-back direction, and the first gripper 312 is provided with a first inclined surface 3121;

[0074] A drive block 313 is disposed on the first gripper 312. The drive block 313 is provided with a second inclined surface 3131. The first inclined surface 3121 and the second inclined surface 3131 are in contact and can slide relative to each other.

[0075] The first cylinder 314 is located on the first bracket 311. The first cylinder can drive the drive block 313 to move in the up and down direction, thereby causing the drive block 313 to drive the first gripper 312 to move in the direction of approaching or moving away from the transport track 200.

[0076] In this configuration, the first cylinder 314 causes the drive block 313 to move vertically. Due to the mutual sliding of the inclined planes, the drive block 313 enables the first gripper 312 to move horizontally. The inclined planes convert the horizontal force into a vertical force. When the two grippers interact, the pressure of the second gripping assembly on the first gripper 312 is directed towards the first gripper 312. However, due to the inclined planes, only a portion of the downward force acts on the first cylinder, while the remaining force is distributed in other directions. Therefore, the force of the first cylinder 314 is greater than that of the second cylinder 323. The rigidity of the first gripping assembly 310 is stronger than that of the second gripping assembly 320, and the end face of the first gripping assembly 310 will not deviate from the reference plane, resulting in high workpiece positioning accuracy. The first cylinder 314 is not located in the direction of movement of the first gripper 312, making the overall length of the first gripper 312 smaller in the front-rear direction, resulting in a more compact overall structure, which is beneficial for arranging the machining mechanism.

[0077] In some embodiments, the drive block 313 is provided with a wedge block 3132 on the side near the second inclined surface 3131. The wedge block 3132 extends along the tangential direction of the second inclined surface 3131. The first gripper 312 is provided with a wedge groove that cooperates with the wedge block 3132. The wedge block 3132 can slide in the wedge groove.

[0078] In this configuration, the wedge block 3132 allows the first inclined surface 3121 and the second inclined surface 3131 to remain in contact. When the second inclined surface 3131 moves up and down, it can also move left and right.

[0079] It should be noted that a wedge shape is similar to an inverted triangle, meaning it is a shape that is pointed at the bottom and thicker at the top. A wedge is an irregular cross-section shape of wood or stone; generally, this cross-section should have sharp corners, like a wedge. The wedge block 3132 can be placed on either side of the inclined plane or on the inclined surface of the plane. The wedge block 3132 can also be a fan-shaped block or a polygonal block, as long as it can create a relative force between the driving block 313 and the first gripper 312.

[0080] In some embodiments, the first clamping assembly 310 further includes a first guide rail 315 extending in the front-rear direction, the first guide rail 315 being disposed on the first bracket 311, and the first gripper 312 being able to slide along the first guide rail 315.

[0081] In this configuration, the guide rail ensures that the moving parts achieve precise linear displacement in a given direction, guaranteeing the accuracy and stability of the motion; the design of the guide rail reduces friction between moving parts, making the motion lighter and smoother.

[0082] In some embodiments, the first inclined plane 3121 has an inclination angle greater than 60 degrees with the horizontal plane.

[0083] In this configuration, when the inclination angle of the inclined plane is 45 degrees, the distance the drive block 313 moves up and down is equal to the distance the first gripper 312 moves left and right when the first inclined plane 3121 and the second inclined plane 3131 slide relative to each other. When the inclination angle of the inclined plane is greater than 45 degrees, the distance the drive block 313 moves up and down is greater than the distance the first gripper 312 moves left and right when the first inclined plane 3121 and the second inclined plane 3131 slide relative to each other. Setting the inclination angle to be greater than 60 degrees can, firstly, shorten the width of the first gripper 312 in the front-back direction, and secondly, control the smaller movement length of the first gripper 312 by the larger movement length of the drive block 313, which is beneficial to improving the movement accuracy of the drive block 313. When the first clamping component 310 and the second clamping component 320 interact, the larger the inclination angle, the smaller the force acting on the first clamping component 310, and the greater the rigidity of the first clamping component 310.

[0084] It is understandable that the horizontal plane is the plane containing the front-back and left-right directions.

[0085] In some embodiments, the second clamping component 320 includes:

[0086] Second support 321;

[0087] The second gripper 322 is slidably disposed on the second bracket 321 in the front-back direction;

[0088] The second cylinder 323 drives the second gripper 322 to move in a direction that is closer to or further away from the transport track 200.

[0089] In this configuration, the second gripper 322 is driven by the second cylinder 323 to clamp the workpiece, causing the first clamping assembly 310 and the second clamping assembly 320 to interact.

[0090] In some embodiments, the second clamping assembly 320 further includes a second guide rail 324 extending in the front-rear direction, the second guide rail 324 being disposed on the second bracket 321, and the second gripper 322 being able to slide along the second guide rail 324.

[0091] In this configuration, the guide rail ensures that the moving parts achieve precise linear displacement in a given direction, guaranteeing the accuracy and stability of the motion; the design of the guide rail reduces friction between moving parts, making the motion lighter and smoother.

[0092] In some embodiments, a locking component 700 is also included, the locking component 700 comprising:

[0093] A locking lever is provided in the first clamping assembly 310;

[0094] The third cylinder is used to drive the locking lever to move in a direction close to or away from the transport track 200, so that the locking lever presses against the front or rear of the workpiece.

[0095] In this configuration, after the first clamping assembly 310 and the second clamping assembly 320 interact to clamp the workpiece, the fastening assembly drives the locking rod to move through the third cylinder, so that the locking rod abuts against the workpiece, increasing the force in the direction of the first clamping assembly 310 and increasing the stability of the first clamping assembly 310.

[0096] In some embodiments, a crimping mechanism 800 is further included, the crimping mechanism comprising:

[0097] Pressure bar 810 is installed on frame 100;

[0098] The fourth cylinder 820 is used to drive the pressure rod 810 to move in the up and down direction, so that the pressure rod 810 presses against the top of the workpiece.

[0099] In this configuration, after the first clamping mechanism 300 clamps the workpiece and moves it to the corresponding position, the pressure rod 810 presses the workpiece from top to bottom, so that the workpiece can maintain a stable position. Then, the processing mechanism and the cutting mechanism 600 process the workpiece to prevent the workpiece position from deviating due to vibration during processing, which would lead to processing errors.

[0100] In some embodiments, at least two crimping mechanisms 800 are provided, and the crimping mechanisms 800 are respectively provided at the entrance and exit of the transport track 200.

[0101] With this setup, multiple pressure points are added, which is beneficial for workpiece fastening. The workpiece processing position is mainly located in the middle of the transport track 200. The pressing mechanism 800 presses the two ends of the workpiece, which can ensure the stability of the workpiece position in the middle and achieve high processing accuracy.

[0102] In some embodiments, the translation mechanism 400 includes a linear motor or a cylinder.

[0103] In some embodiments, a feeding track 910 is also included, with the inlet of the feeding track 910 located at the outlet of the transport track 200, and the cutting mechanism 600 located between the feeding track 910 and the transport track 200.

[0104] In this configuration, the feeding track 910 is located at the end of the transport track 200. The workpieces after drilling and cutting are placed on the feeding track 910 and can be transported one by one along the feeding track 910 after completion.

[0105] It should be noted that a conveyor belt may be provided on the feeding track 910 for transporting workpieces, or when the workpiece is pushed by the translation mechanism 400, the side of the long strip workpiece near the exit of the transport track 200 pushes the workpiece so that the workpieces are transported one by one.

[0106] In some embodiments, a second clamping mechanism 920 is also included, which is located at the entrance of the feeding track 910.

[0107] In this configuration, the clamping component and the second clamping component 320 are positioned between the cutting mechanism 600 and the clamping component 600. During cutting, the clamping mechanism and the second clamping component 320 can secure the workpiece located on both sides of the cutting mechanism 600, making the cutting process more stable and improving cutting efficiency.

[0108] In some embodiments, the first processing component 510 includes:

[0109] The first drilling machine is located in front of the transport track 200. The first drilling machine is used to move in the back-and-forth direction and drill holes in the workpiece.

[0110] The first tapping machine is located in front of the transport track 200. The first tapping machine is used to move in the back-and-forth direction and tap the workpiece.

[0111] The first driving component is used to drive the first drilling machine and the first tapping machine to move in the vertical direction;

[0112] The second driving component is used to drive the first drilling machine and the first tapping machine to move in the left and right directions.

[0113] The second processing unit includes:

[0114] The second drilling machine is located behind the transport track 200. The second drilling machine is used to move in the front-back direction and drill holes in the workpiece.

[0115] The second tapping machine is located behind the transport track 200. The second tapping machine is used to move in the front-back direction and tap the workpiece.

[0116] The third driving component is used to drive the second drilling machine and the second tapping machine to move in the vertical direction;

[0117] The fourth driving component is used to drive the second drilling machine and the second tapping machine to move in the front-back direction.

[0118] In some embodiments, the third processing component 530 includes:

[0119] The third drilling machine is located above the transport track 200. The third drilling machine is used to move in the vertical direction and drill holes in the workpiece.

[0120] The fifth driving component is used to drive the third drilling machine to move in the left and right directions;

[0121] The sixth drilling machine is used to drive the third drilling machine to move in the forward and backward direction.
