[0002] The pretreatment of the drill body refers to a series of processing steps performed on the drill body before final processing; these pretreatment steps are intended to create optimal conditions for final processing and ensure that the drill bit can meet the design requirements and standards during the processing. Traditional drill body pretreatment includes surface treatment of the drill bit to improve its surface quality, accuracy and geometry. Surface treatment includes grinding and milling, which can be used to adjust the geometry of the drill bit, such as correcting the angle of the blade, the smoothness of the edge, etc., to ensure that the drill bit can achieve the expected cutting effect.

[0003] When traditional drill bit blank materials are being ground, they are mostly ground manually with a grinding wheel grinder. During this period, the drill bit blank is manually pushed forward by hand so as to contact the grinding wheel to achieve the grinding operation on the drill bit blank. However, this operation method is affected by factors such as the operator's pushing speed and stability. When batch grinding operations are performed, the material pushing distance is not accurate enough, which easily leads to incomplete grinding and poor consistency, affecting the overall structural stability and grinding consistency of the blank material. At the same time, manual pushing of the drill bit blank requires the operator to expend a lot of physical strength and energy, especially in the case of large-scale grinding. Therefore, a blank pretreatment device for drill bit production is proposed to solve the above problems. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example

[0022] Depend on Figure 1-3 A drill bit production embryo body pretreatment device is provided, comprising a drill bit pretreatment platform 1; a lifting assembly 2 is mounted on the drill bit pretreatment platform 1; a drill bit embryo body conveying assembly 3 is carried on the lifting assembly 2;

[0023] The drill bit embryo body 4 is assembled in the drill bit embryo body transmission component 3;

[0024] The lifting assembly 2 includes a guide rod cylinder 21 arranged on the drill bit pre-processing platform 1. The output end of the guide rod cylinder 21 is connected to a connecting seat 22. Two bearing seats 23 are installed on the outside of the connecting seat 22. The upper end surfaces of the two bearing seats 23 jointly support the drill bit blank conveying assembly 3.

[0025] The drill bit blank transmission assembly 3 includes an adjustment seat 31 arranged on the upper end surface of the supporting seat 23. The upper end surface of the adjustment seat 31 is provided with a rectangular groove and a slider seat 33 is slidably arranged therein. The upper end surface of the slider seat 33 carries a supporting plate 34. The upper end surface of the supporting plate 34 is installed with a mounting seat 35 and a blank mounting tube 36. The drill bit blank 4 is movably arranged in the blank mounting tube 36.

[0026] In this embodiment, through the mutual movement and coordination of multiple components in the drill bit blank transmission assembly 3, drill bit blanks 4 of different diameters can be fixed in the blank mounting tube 36. At the same time, driven by the rotation of the small screw 32, the blank mounting tube 36 can drive the drill bit blank 4 to move back and forth linearly along the stroke range of the small screw 32, thereby driving the drill bit blank 4 to move accurately to one side of the grinding wheel grinder body 5, so as to complete the pre-treatment and grinding operation of the drill bit blank 4 using the grinding wheel grinder body 5. Compared with traditional manual hand-held operations, the pre-treatment device of the present application can realize precise linear transmission of the drill bit blank 4 through the drill bit blank transmission assembly 3, ensure accurate positioning and stable transmission when grinding the blank, thereby ensuring the accuracy and consistency of the pre-treatment processing. At the same time, compared with manual operations, the present application can also improve the pre-treatment and grinding efficiency of the drill bit blank 4, and reduce manpower labor.

[0027] Furthermore, in actual use, when the grinding wheel grinder body 5 is grinding the drill bit blank 4, the guide rod cylinder 21 provided can drive the connecting seat 22 and the supporting seat 23 to move upward after being connected to the external air source. At this time, through the installation of the supporting seat 23 and the adjustment seat 31, the drill bit blank 4 can also be ground at different heights, so that drill bit blanks 4 of different sizes can be ground with the grinding wheel grinder body 5. At the same time, through the adjustment of the grinding height, the drill bit end and the drill body of the drill bit blank 4 can also be ground separately, thereby improving the grinding effect and grinding range of the drill bit blank 4.

[0028] Specifically, refer to Figure 2-3 A limit plate 37 is vertically installed on the side of the mounting seat 35, and a limit bolt 38 is threadedly connected to the limit plate 37. The end of the limit bolt 38 moves vertically downward and passes through the embryo mounting tube 36 to abut against the drill embryo 4; a through groove is opened on the upper end surface of the embryo mounting tube 36 for the limit bolt 38 to slide.

[0029] In this embodiment, the limiting plate 37 provided can be used to limit the limiting bolt 38. During use, the user places the drill bit blank 4 to be processed in the blank mounting tube 36, and then rotates the limiting bolt 38 to move the end of the limiting bolt 38 downward until the end of the limiting bolt 38 abuts against the top of the drill bit blank 4. At this time, the drill bit blank 4 is surrounded by the blank mounting tube 36 and the limiting bolt 38 is tightly abutted, so that the drill bit blank 4 can be stably installed in the blank mounting tube 36.

[0030] Furthermore, by pressing down the limiting bolt 38, drill bit blanks 4 of different sizes can be positioned in the blank mounting tube 36, thereby improving the applicability of the pretreatment device of the present application. In a more preferred embodiment, the blank mounting tube 36 is installed on the supporting plate 34 by means of bolt positioning, so that the user can also replace the blank mounting tube 36 to adapt to the installation of larger-sized drill bit blanks 4.

[0031] Specifically, refer to Figure 2-3 A small lead screw 32 is provided for rotation in the adjustment seat 31. The small lead screw 32 passes through the slider seat 33 and is engaged with it. A reciprocating motor 39 is installed on one side of the adjustment seat 31. The output end of the reciprocating motor 39 passes through the adjustment seat 31 and is connected to one end of the small lead screw 32.

[0032] In this embodiment, the adjustment seat 31 is used to limit the small screw 32. During use, the reciprocating motor 39 is used to drive the small screw 32 to rotate. The user can connect the power supply to the reciprocating motor 39. Through the drive of the reciprocating motor 39, the small screw 32 can rotate synchronously with the reciprocating motor 39. When the small screw 32 rotates, it is limited by the adjustment seat 31, so that the slider seat 33 engaged on the small screw 32 can drive the supporting plate 34 to move in a straight line along the travel range of the small screw 32.

[0033] Specifically, refer to Figure 2-3 The upper end surface of the adjustment seat 31 is provided with a blank supporting hoop 310 , and a bolt hole is opened at the bottom of the blank supporting hoop 310 and a bolt member is connected to the internal thread thereof. The blank supporting hoop 310 is detachably provided on the adjustment seat 31 by the bolt member.

[0034] In this embodiment, the provided embryo support hoop 310 can be used to support the drill rod body of the drill bit embryo 4, thereby further improving the stability of the drill bit embryo 4 during grinding. In a preferred embodiment, the provided embryo support hoop 310 can be freely replaced to adapt to the size of the drill bit embryo 4, so as to facilitate stable support of the drill bit embryo 4.

[0035] Specifically, refer to Figure 1The upper end surface of the drill pre-processing platform 1 is equipped with a grinding wheel grinder body 5, and the grinding side of the grinding wheel grinder body 5 is arranged on one side of the drill blank transmission component 3.

[0036] In this embodiment, the grinding wheel grinder body 5 is an existing mature grinding equipment, which can be used to grind the drill bit blank 4, thereby achieving a pre-treatment operation on the drill bit blank 4.

[0037] The utility model is a pre-treatment device for the embryo body used in drill bit production:

[0038] Step 1: In actual use, when the user needs to pre-process the drill bit body 4, the user places it in the body mounting tube 36. Then, the user rotates the limiting bolt 38 to move the end of the limiting bolt 38 downward until the end of the limiting bolt 38 abuts against the top of the drill bit body 4. At this time, the drill bit body 4 is stably installed in the body mounting tube 36 due to the surrounding of the drill bit body 4 by the body mounting tube 36 and the tight abutment of the limiting bolt 38.

[0039] Step 2: After the drill bit blank 4 is loaded, the user can connect the power supply to the reciprocating motor 39. The reciprocating motor 39 drives the small lead screw 32 to rotate synchronously with the reciprocating motor 39. When the small lead screw 32 rotates, it is limited by the adjusting seat 31, so that the slider seat 33 engaged with the small lead screw 32 can drive the supporting plate 34 to move linearly along the travel range of the small lead screw 32. The supporting plate 34 is connected with the mounting seat 35 and the blank mounting tube 36, so that the drill bit blank 4 in the blank mounting tube 36 can move accordingly. The user controls the rotation direction of the small lead screw 32 and gradually moves the drill bit blank 4 until it fits into contact with the grinding wheel grinder body 5. At this time, the pre-treatment grinding operation of the drill bit blank 4 can be achieved through the contact between the grinding wheel grinder body 5 and the drill bit blank 4.

[0040] Step 3: The user connects the guide rod cylinder 21 to an external air source so that the guide rod cylinder 21 can drive the connecting seat 22 and the supporting seat 23 to move upward. At this time, through the installation of the supporting seat 23 and the adjusting seat 31, the drill bit blank 4 can also be ground at different heights, so that drill bit blanks 4 of different sizes can be ground with the grinding wheel grinder body 5. At the same time, through height adjustment, the drill bit end and the drill body of the drill bit blank 4 can also be ground separately.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
