Description

Technical Field

[0001] The invention relates to the technical field of drill bit processing, in particular to drill bit shape finishing processing equipment. Background Art

[0002] A drill bit is a cutting tool used in drills and excavation machines to create circular holes. The basic principle of a drill bit is to rotate while cutting the workpiece, and then remove the cuttings through the drill flute. Common drill bits include twist drills, spade drills, center drills, deep hole drills, and trepan drills. During the production process, the drill bit undergoes trimming and shaping to achieve a more refined finish and maximize its performance.

[0003] During the production process of existing drill bits, cutting produces burrs, bumps, and other defects, resulting in insufficient surface smoothness. These bits are typically polished and trimmed, requiring a corresponding profile trimming device. Patent number CN215617152U discloses a drill bit profile trimming and shaping device comprising a base box, a hood fixed to the top of the base box, a housing fixed to one inner wall of the hood, a first threaded rod rotatably connected to the inner wall of the housing, a first threaded block threadedly connected to the outer wall of the first threaded rod, a connecting rod hinged to the top of the first threaded block, a swing arm hinged to the upper end of the inner wall of the hood, and a clamping mechanism fixed to the end of the swing arm. This device adjusts the angle of the drill bit so that its grooves match those of the grinding disc, facilitating adaptation to grooves of different sizes.

[0004] After analyzing the above equipment, we can find that its main function is to accurately position the drill bit and then grind different types of grooves on it. Although it can play a certain finishing role, there are still the following problems during the operation:

[0005] First, due to the special trajectory of the flutes, when grinding and correcting the drill bit shape, it is necessary to constantly adjust the operating angle of the drill bit or the grinding structure. This process is difficult to operate and needs to be done continuously, which affects the overall dressing speed of the drill bit.

[0006] Furthermore, it is inconvenient to grind and trim multiple drill bits at the same time. When faced with large-scale drill bit production, the equipment is not efficient enough and cannot be applied;

[0007] Finally, during the operation of the entire equipment, there is a lack of effective connection between the various power transmissions for the collection and treatment of impurities and the adjustment of the grinding and finishing speed, making it impossible to fully convert and utilize the power;

[0008] Therefore, in view of the above-mentioned problems, the present technical solution proposes a drill bit shape finishing processing equipment. Summary of the Invention

[0009] The purpose of the present invention is to provide a drill bit profile finishing and processing equipment to solve the problems raised in the above background technology.

[0010] To achieve the above-mentioned object, the present invention provides the following technical solutions: a drill bit profile finishing and processing device, comprising a finishing and processing table, forming a drill bit grinding and finishing base;

[0011] The grinding and trimming area is arranged on one side of the top of the trimming processing table. There are multiple groups of clamping assemblies for positioning and driving the rotation of the two ends of the drill bit arranged in parallel inside the grinding and trimming area. The drill end of the drill bit is against one end of the clamping assembly, and the drill rod end is inserted and fixed in the other end of the clamping assembly, so as to keep the groove of the drill bit fully exposed and fully accept the rotation grinding and trimming processing. A standard trajectory guide ball is swingably set just above the middle clamping assembly, and the drill bit below the standard trajectory guide ball is set to the standard type after trimming. A grinding and trimming knife is swingably set just above the clamping assemblies on both sides, and the drill bit below the grinding and trimming knife is set to the type to be trimmed. Grinding pressure blocks are installed on the top of the grinding and trimming knife and the standard trajectory guide ball, and one side of the grinding pressure block is connected to a balancing swing assembly through a trimming swing rod. The balancing swing assembly cooperates with the grinding pressure block to drive the grinding and trimming knife to perform fast moving grinding and trimming on the drill bit to be trimmed under the guidance limit of the standard trajectory guide ball;

[0012] The mobile feeding mechanism is connected to both sides of the balancing swing assembly and is used to drive the balancing swing assembly to move along the length direction of the drill bit, thereby driving the grinding and trimming knife to grind the drill bit grooves;

[0013] One end of the clamping assembly away from the balancing swing assembly is commonly connected to a rotary drive assembly, one side of the rotary drive assembly is connected to a speed regulating transmission assembly, and the driving end of the speed regulating transmission assembly is connected to a mobile feed mechanism. The mobile feed mechanism drives the speed regulating transmission assembly to rotate while controlling the grinding and trimming knife and the standard trajectory guide ball to move along the drill bit. At the same time, the speed regulating function of the speed regulating transmission assembly is utilized to control the rotary drive assembly to drive the clamping assembly to rotate at a desired speed, thereby controlling the drill bit to rotate, and cooperating with the movement of the grinding and trimming knife and the standard trajectory guide ball to grind the surface grooves thereof.

[0014] The self-priming impurity collection mechanism is installed inside the finishing table on the lower side of the grinding and finishing area. The driving end of the self-priming collection mechanism is rotatably connected to the rotary drive assembly. That is, while controlling the rotation of the drill bit, the self-priming impurity collection mechanism is synchronously driven to operate, automatically absorbing and collecting the debris and impurities generated by grinding on the drill bit;

[0015] Among them, before processing, a standard drill bit after trimming is pre-selected and installed in the grinding and trimming area below the standard trajectory guide ball through the clamping assembly, and then the drill bits to be trimmed are distributed and installed under the grinding and trimming knives on both sides of the standard trajectory guide ball. Then, under the swing of the balancing swing assembly, the bottom end of the standard trajectory guide ball contacts the corresponding drill bit. At this time, the mobile feed mechanism runs, driving the standard trajectory guide ball and the grinding and trimming knife to move. At the same time, according to the grinding speed of the drill bit, the speed regulation transmission assembly is used to control the rotation drive assembly to drive the drill bit to rotate at an appropriate speed. Then, under the guidance of the standard trajectory guide ball, the grinding and trimming knife performs standardized mobile grinding on the drill bit groove on its lower side, and under the action of the self-priming impurity collection mechanism, the impurities generated by grinding are automatically collected, thereby realizing the function of standard automatic grinding and trimming of large quantities of drill bits, and at the same time, in conjunction with the transmission of each structure connection, the kinetic energy is maximized to achieve an energy-saving and efficient operation mode.

[0016] Compared with the prior art, the beneficial effects of the present invention are: by adopting standard trajectory guide balls and standard drill bit movement trajectory guidance, then setting multiple groups of drill bits to be trimmed and cooperating with grinding and trimming knives, and then controlling the drill bits to roll, thereby achieving simultaneous feed-moving precise grinding and trimming of multiple drill bits, fully improving the scope of application of the equipment;

[0017] The drill bit is squeezed and positioned by the clamping assembly so that its grooves are fully exposed, and combined with its rotation, the surface can be covered and polished;

[0018] The main drive motor is used to drive the standard trajectory guide ball and the grinding and dressing knife to move. Then, under the action of the speed control transmission component and the rotary drive component, multiple drill bits are synchronously driven to operate at adjustable speeds. In addition, under the connection of the helical gear II, helical gear I, transmission rod and other structures, multiple suction fans are driven to rotate at the same time, thereby accelerating the collection of impurities during drill bit dressing and realizing the full conversion and utilization of kinetic energy. In addition, the system has strong adjustability and has the advantages of energy saving and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] See also Figures 1-4 , a drill bit shape finishing processing equipment, including a finishing processing table 10, forming a drill bit grinding and finishing base;

[0034] The grinding and trimming area 14 is set on one side of the top of the trimming table 10. There are multiple sets of clamping assemblies for positioning and rotating the two ends of the drill bit in parallel inside the grinding and trimming area 14. The drill end of the drill bit is against one end of the clamping assembly, and the drill rod end is plugged and fixed in the other end of the clamping assembly, so as to keep the groove of the drill bit fully exposed and fully accept the rotary grinding and trimming processing. A standard track guide ball 17 is swingably set just above the middle clamping assembly, and the drill bit below the standard track guide ball 17 is set to the trimmed Standard type, a grinding and trimming knife 16 is swingably set just above the clamping components on both sides, and the drill bit below the grinding and trimming knife 16 is set to the type to be trimmed. The grinding and trimming knife 16 and the top of the standard trajectory guide ball 17 are both installed with a grinding pressure block 18. One side of the grinding pressure block 18 is connected to a balancing swing component through a trimming swing rod 27. The balancing swing component cooperates with the grinding pressure block 18 to drive the grinding and trimming knife 16 to perform fast moving grinding and trimming on the drill bit to be trimmed under the guidance and restriction of the standard trajectory guide ball 17;

[0035] The mobile feeding mechanism is connected to both sides of the balancing swing assembly and is used to drive the balancing swing assembly to move along the length direction of the drill bit, driving the grinding and trimming knife 16 to grind the drill bit grooves;

[0036] One end of the clamping assembly away from the balancing swing assembly is commonly connected to a rotary drive assembly, one side of the rotary drive assembly is connected to a speed regulating transmission assembly, and the driving end of the speed regulating transmission assembly is connected to the mobile feed mechanism. The mobile feed mechanism drives the speed regulating transmission assembly to rotate while controlling the grinding and trimming knife 16 and the standard trajectory guide ball 17 to move along the drill bit. At the same time, the speed regulating function of the speed regulating transmission assembly is used to control the rotary drive assembly to drive the clamping assembly to rotate at a required speed, thereby controlling the drill bit to rotate, and cooperating with the movement of the grinding and trimming knife 16 and the standard trajectory guide ball 17 to grind the surface grooves thereof.

[0037] A self-priming impurity collection mechanism is provided inside the finishing table 10 below the grinding and finishing area 14. The driving end of the self-priming collection mechanism is rotatably connected to the rotary drive assembly. That is, while controlling the rotation of the drill bit, the self-priming impurity collection mechanism is synchronously driven to operate, automatically absorbing and collecting debris and impurities generated by grinding on the drill bit.

[0038] Among them, before processing, a standard drill bit after trimming is pre-selected and installed in the grinding and trimming area 14 below the standard trajectory guide ball 17 through the clamping assembly, and then the drill bits to be trimmed are distributed and installed under the grinding and trimming knives 16 on both sides of the standard trajectory guide ball 17. Then, under the swing of the balancing swing assembly, the bottom end of the standard trajectory guide ball 17 contacts the corresponding drill bit. At this time, the mobile feed mechanism runs, driving the standard trajectory guide ball 17 and the grinding and trimming knife 16 to move. At the same time, according to the grinding speed of the drill bit, the speed regulating transmission assembly is used to control the rotation drive assembly to drive the drill bit to rotate at an appropriate speed. Then, under the guidance of the standard trajectory guide ball 17, the grinding and trimming knife 16 performs standardized mobile grinding on the drill bit groove on its lower side, and under the action of the self-priming impurity collection mechanism, the impurities generated by grinding are automatically collected, thereby realizing the function of standard automatic grinding and trimming of large quantities of drill bits, and at the same time, in conjunction with the connection transmission of each structure, the kinetic energy is maximized to achieve an energy-saving and efficient operation mode.

[0039] In the embodiment of the present invention, a drill bit holder 15 is fixedly mounted on the finishing table 10 on one side of the grinding and finishing area 14. A baffle is fixedly mounted between the drill bit holder 15 and the two sets of columns 11 on the corresponding side. The space between the baffle and the drill bit holder 15 is the area corresponding to the grinding and finishing area 14.

[0040] Under normal conditions, the gravity of one end of the balancing swing assembly close to the grinding pressure block 18 is greater than that of the other end, that is, the standard trajectory guide ball 17 and the grinding and trimming knife 16 are kept falling, and the standard trajectory guide ball 17 and the grinding and trimming knife 16 are controlled to always be in contact with the drill bit. Then, the grinding and trimming knife 16 grinds and trims the defective drill bit grooves on the lower side according to the movement of the standard trajectory guide ball 17 along the drill bit.

[0041] At the same time, the grinding and trimming knife 16, the standard trajectory guide ball 17 and the grinding pressure block 18 at the top thereof are detachably connected. That is, according to the type of drill bit to be trimmed and the degree of trimming, the grinding pressure block 18 of appropriate weight is selected to ensure that it cooperates with the balanced swing assembly to fully contact and grind the drill bit;

[0042] A rectangular impurity collection trough 19 is provided in the dressing table 10 at the corresponding grinding and finishing area 14 of the self-priming impurity collection mechanism, which runs through the top and bottom. A trough bottom plate 20 is plug-in installed at the bottom of the impurity collection trough 19, and a V-shaped impurity collection filter 28 is installed inside the top. The self-priming impurity collection mechanism is placed inside the trough bottom plate 20, and its adsorption output end is distributed toward one side of the V-shaped impurity collection filter 28. The debris and impurities falling from the drill bit are absorbed by gravity through the V-shaped impurity collection filter 28 and stored in the trough bottom plate 20. At the same time, in order to facilitate the control of the installation and disassembly between the trough bottom plate 20 and the impurity collection trough 19, a plurality of legs are evenly installed at the four corners of the bottom of the dressing table 10;

[0043] Among them, the trough bottom plate 20 and the impurity collecting trough 19 can adopt a variety of detachable connection methods, such as snap connection, plug connection, sliding connection, etc., and the specific method depends on the actual situation;

[0044] The bottom end of the standard trajectory guide ball 17 is set to a smooth structure, which allows it to move along the standard drill bit groove while making full contact without causing wear to it, and then guides the grinding knife structure at the bottom end of the grinding and trimming knife 16 to perform standardized grinding on the drill bit groove to be trimmed.

[0045] In one embodiment of the present invention, the mobile feed mechanism includes four columns 11 fixedly mounted at the four corners of the top of the trimming table 10. A moving assembly and a supporting assembly are respectively arranged between two columns 11 distributed along the length direction of the drill bit. A balancing swing assembly is rotatably arranged between the moving assembly and the supporting assembly to stably control the balancing swing assembly to drive the grinding and trimming blade 16 and the standard trajectory guide ball 17 to move along the drill bit.

The other end of the lead screw 21 passes through the column 11 and is connected to the speed control transmission assembly. That is, when the main drive motor 12 is started, the lead screw 21 is driven to rotate, thereby driving the nut 22 to move back and forth along the lead screw 21.

[0047] Specifically, the support assembly includes a support slide rod 23 rotatably arranged between the two groups of columns 11, a support slider 24 is slidably connected to the support slide rod 23, and the balance swing assembly is arranged between the support slider 24 and the nut 22, that is, it moves synchronously with the nut 22.

A mounting tube 26 is fixedly sleeved on the middle part of the swing spindle 25. The side of the mounting tube 26 facing the grinding and trimming blade 16 and the standard trajectory guide ball 17 is fixedly connected to the trimming swing rod 27 via a fixing ring. At the same time, a balancing block 58 is detachably mounted on the side of the middle fixing ring relative to the trimming swing rod 27 via a straight rod. That is, the gravity distribution between the balancing block 58 on one side and the grinding pressure block 18 on the other side is utilized to maintain the swinging arrangement between the grinding and trimming blade 16, the standard trajectory guide ball 17 and the drill bit.

Then, the locking nut 31 is rotated to gradually apply radial pressure to the external thread 30 at the segmented position, thereby tightening the drill bit at the drill rod.

[0051] It should be noted that when the external thread 30 is in the initial state, it is in an open expansion structure, which facilitates the insertion of the drill bit and drill rod into the internal structure, and then the locking nut 31 is used to radially shrink and fix it;

The end of the screw rod 33 on the other side is connected to the rotary drive assembly through a connecting rod. By rotating the screw barrel 32, the depth of the screw rods 33 at both ends is adjusted, thereby controlling the butt plate 34 to tighten and contact the drill end of the drill bit and fix it. Then, under the drive of the rotary drive assembly, the fixed drill bit is controlled to rotate. By fixing the two ends of the drill bit with the butt plate 34 and the external thread 30, the drill bit groove can be kept fully exposed to accept the grinding and shaping of the upper grinding and trimming knife 16.

A gear rod is fixedly installed at the center of the super-large speed regulating gear 38, large speed regulating gear 39, medium speed regulating gear 40, and small speed regulating gear 41. The gear rod is rotated away from the side of the dressing table 10 and is provided with a radially distributed rotary positioning sleeve rod 42.

The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control. Before processing, a standard drill bit after trimming is pre-selected, and the two ends of the drill bit are positioned by the external thread 30 and the abutment plate 34. At the same time, the grooves of the drill bit are fully exposed, and then the drill bits to be trimmed are distributed and installed under the grinding and trimming knives 16 on both sides of the standard trajectory guide ball 17, and then the main drive motor 12 is started to start the screw 21 to rotate, driving the installation cylinder 26 along the direction of the drill bit.
