Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a new type of drilling and tapping machine. Background Technology

[0002] In traditional processing and production, drilling and tapping are often two separate processes that require two separate machines. This is not only cumbersome to operate, but also prone to misalignment after changing the clamping fixture, resulting in processing quality problems. On the other hand, it also increases the investment cost of the equipment.

[0003] Existing processing procedures sometimes use the same equipment, performing drilling and tapping operations by changing the drill bit and tapping tap respectively. This method involves many steps, is labor-intensive, and has low processing efficiency, hindering mechanization and assembly line production. Furthermore, the conventional use of ordinary bench vises for clamping results in low processing precision, compromising product quality. Additionally, the large-batch production of products generates significant amounts of waste, further impacting production efficiency. Summary of the Invention

[0019] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0020] like Figures 1 to 4 The diagram shown is a structural schematic of the novel drilling and tapping machine provided by this utility model. The novel drilling and tapping machine includes a frame 10, a rotating mechanism 20 mounted on the frame 10, multiple product clamps 30 mounted on the rotating mechanism 20, two processing devices 40 mounted on both sides of the rotating mechanism 20, and a chip removal mechanism 50 mounted within the frame 10. It is conceivable that the novel drilling and tapping machine also includes other functional modules such as loading and unloading mechanisms, electrical control cabinets, etc., which are technologies well known to those skilled in the art and will not be described in detail here.

[0021] The frame 10 includes a fixed frame 11, a plurality of side plates 12 disposed between the fixed frame 11, and a workbench 13 disposed on the fixed frame 11, and includes a plurality of other components, including but not limited to cable trays, digital displays and locks, which are all common technologies used in industrial production equipment, and therefore will not be described in detail here.

[0022] The fixed frame 11 can be a frame structure constructed using aluminum profiles and fasteners. The bottom is equipped with casters for easy movement of the frame 10 and support legs for position fixation, providing support and stability to the main body. The side panels 12 are multiple door panels mounted on the fixed frame 11, equipped with hinges, handles, and locks to enclose the interior of the frame 10, facilitating wiring or placement of other precision instruments. The workbench 13 is located on the fixed frame 11 and is a plane parallel to the ground, used to house the rotating mechanism 20 and the processing device 40.

[0023] The rotating mechanism 20 includes a drive device 21 disposed within the frame 10, and a turntable 22 disposed on the drive device 21.

[0024] The drive device 21 is a cam divider used to realize the rotation of the rotating mechanism 20 in the circumferential direction. It is a widely used component in automated machinery, such as automatic tool changers in machining centers, which require converting continuous operation into stepping motions. This is well-known to those skilled in the art, and therefore only briefly described here. The drive device 21 is mounted on the worktable 13 and can be fixed in position by fasteners or a fixed frame to support the turntable 22 and maintain its rotational stability.

[0025] The turntable 22 is a circular platform, spaced apart and parallel to the worktable 13. Its center is located on the drive end of the drive device 21 as the rotation center. The platform can rotate along the circumference and is used to set multiple sets of product fixtures 30.

[0026] Multiple product clamps 30 are fixed to the edge of the rotating mechanism 20 by fasteners and are arranged in a circular array. In this embodiment, four product clamps 30 are provided, spaced apart from each other and arranged in a 90° rotational symmetry.

[0027] Each of the product fixtures 30 includes a vertical plate 31, a clamping cylinder 32 disposed on the vertical plate 31, and a contour fixing seat 33 disposed in the downward pressing direction of the clamping cylinder 32.

[0028] The upright plate 31 is a rectangular plate fixedly mounted on the turntable 32, with its surface perpendicular to the turntable 32, for mounting the clamping cylinder 32.

[0029] The main body of the clamping cylinder 32 is fixed on the upright plate 31, and the driving end extends toward the contour fixing seat 33 and a pressure block is provided at the end of the driving end. Preferably, the driving direction of the clamping cylinder 32 is vertically downward, so as to apply a vertical pressure to the product placed in the contour fixing seat 33, thereby ensuring that the product placed in the contour fixing seat 33 will not be displaced due to external force when drilling and tapping operations are performed.

[0030] The contouring fixing seat 33 is fixed to the edge of the turntable 32 by fasteners and is located directly below the clamping cylinder 32, so that different models of the contouring fixing seat 33 can be replaced according to different products. The contouring fixing seat 33 is provided with two limiting grooves 331. The shape of the groove 331 is consistent with the shape of the product, so that the product can be precisely inserted into the limiting groove 331 and limited.

[0031] The two processing devices 40 are arranged on both sides of the turntable 32, and each includes a support column 41 arranged on the worktable 13, a displacement mechanism 42 arranged on the support column 41, and a power head 43 arranged on the displacement mechanism 42.

[0032] The support column 41 is fixed to the worktable 13 by fasteners and is located on one side of the turntable 32 to support the displacement mechanism 42 and the power head 43.

[0033] The displacement mechanism 42 is a feeding device that moves towards the turntable 32 through the driving action of a motor. Alternatively, it can be a servo motor or cylinder or other driving device with the driving direction towards the turntable 32. No specific restrictions are made here.

[0034] The power head 43 is mounted on the drive end of the displacement mechanism 42 and faces the turntable 32. The power head 33 is a motor-driven rotary head, which can be a drill bit for grinding, a milling head for cutting, or a wire wheel for grinding; the type and specifications can be changed according to the actual process. In this embodiment, two different rotary heads are provided in the two processing devices 40. One power head 43 has two drill bits for drilling, and the other power head 43 has two taps for tapping.

[0035] The chip removal mechanism 50 includes two chip removal ports 51 opened on the workbench 13, a chip baffle plate 52 arranged around the fixed frame 11, a chip removal groove 53 arranged between the workbench 13 and the chip baffle plate 52, a waste chip collection hopper 54 arranged in the fixed frame 11, a waste chip collection port 55 opened on the side plate 12, and a waste chip collection box 56 arranged on one side of the frame 10.

[0036] The chip discharge port 51 is an opening formed on the worktable 13, located directly below the processing point where the power head 43 contacts the product placed on the contour fixing seat 33, so that the chips generated during processing can fall into the waste chip collection hopper 54.

[0037] The chip baffle 52 is disposed on the top of the fixed frame 11 and surrounds the top surface. It is a plane perpendicular to the workbench 13 and can be a sheet metal plate, in order to prevent debris falling on the workbench 13 from falling from the edge of the workbench to the ground where the equipment is located.

[0038] The chip removal groove 53 is located at the edge of the workbench 13. One side wall of the chip removal groove 53 is the chip baffle 52, and the other side wall is the side edge of the workbench 13. The bottom of the groove is the fixed frame 11, and the side of the workbench 13 is connected to the interior of the fixed frame 11. So when the chips fly and fall on the workbench 13, the user can blow the chips with a device such as a hair dryer, so that the chips hit the chip baffle 52 and bounce into the chip removal groove 53, and fall into the waste chip collection hopper 54 from the gap at the bottom of the groove.

[0039] The waste collection hopper 54 is disposed inside the fixed frame 11 and located directly below the workbench 13, and is a funnel-shaped structure. The opening of the waste collection hopper 54 abuts against the side plate 12, so that both the chip discharge port 51 and the chip discharge groove 53 are within the collection range of the waste collection hopper 54.

[0040] The waste collection port 55 is located on one of the side plates 12 and is connected to the bottom of the waste collection hopper 54 through an inclined material flow channel 57. The waste collection port 55 is located at a height lower than the bottom of the waste collection hopper 54 to facilitate the discharge and collection of waste.

[0041] The waste collection box 56 is disposed on one side of the waste collection port 55 and located below the outlet of the material flow channel 57, for collecting waste discharged from the material flow channel 57.

[0042] In use, the turntable 22 rotates, moving an empty product fixture 30 to the loading station. The loading mechanism places two products into the contour fixing seat 33, and then the clamping cylinder 32 presses down to fix the product position. The turntable 22 rotates to the drilling point opposite the power head 43 with the drilling bit. The displacement mechanism 42 pushes the power head 43 closer to the product to perform the drilling operation, and the generated debris falls into the chip discharge port 51. After the drilling operation is completed, the turntable 22 rotates again to the tapping point opposite the power head 43 with the tapping tap. The displacement mechanism 42 pushes the power head 43 closer to the product to perform the tapping operation, and the generated debris falls into the chip discharge port 51. After the tapping operation is completed, the turntable 22 rotates again to the unloading station, where the unloading mechanism unloads the product.

[0043] Compared with existing technologies, the novel drilling and tapping machine provided by this utility model, through the setting of the rotating mechanism 20 and product fixture 30, adopts a rotary table processing method, allows for customizable parameter settings, high repeatability, high cycle time, and can effectively replace manual labor. Furthermore, by setting the processing device 40, a dedicated drilling and tapping system, multiple processes can be operated simultaneously, resulting in high work efficiency, effectively realizing streamlined production, and simplifying operation, thus reducing labor costs. Simultaneously, by setting the chip removal mechanism 50, fallen and splashed chips are quickly collected simultaneously without the need for manual shutdown for cleaning, improving production efficiency and reducing labor costs.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
