Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of drill shank grinding tooling technology, and more specifically, to drill shank grinding tooling. Background Technology

[0002] In the field of machining, various types of drill rods are often used for hole machining of parts. In the production and processing of drill rods, in order to ensure the cutting performance and service life of the drill bit, a grinding device is needed to grind the drill shank.

[0003] Currently, traditional drill shank grinding is mostly done manually by hand. During the grinding process, it is necessary to ensure that the drill shank axis is parallel to the grinding wheel surface, which is difficult to maintain manually by hand. This can easily lead to uneven wear on the drill shank surface, and excessive grinding in certain areas can reduce the material strength, affecting grinding efficiency and grinding quality. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a drill shank grinding fixture, which solves the technical problems of low efficiency and poor grinding quality of manual hand-held grinding in the prior art.

[0005] According to one aspect, at least one embodiment of this disclosure provides a drill shank grinding fixture, comprising: a base, a baffle, a mounting seat, a grinding mechanism, a slide rail, a slide groove, a guide rod, a threaded screw, a sliding seat, a connecting plate, a reducer, a support wheel, a motor, an adjusting vertical plate assembly, and a scale. The front and rear ends of the base are fixedly connected to baffles. A mounting seat is fixedly connected to the center of the upper end of the base. A motor support is provided at the lower end of the grinding mechanism. The grinding mechanism is fixedly mounted on the upper end of the mounting seat via the motor support. A slide rail is fixedly connected to the upper end of the mounting seat in front of the grinding mechanism. The slide rail has a sliding groove. The slide rail frame has two symmetrically arranged guide rods inside, with a threaded screw between the two guide rods. Both ends of the threaded screw are movably connected to the slide rail frame. A rotating rod is provided at one end of the threaded screw that extends out of the slide rail frame. A sliding seat is slidably connected inside the slide rail frame. A sliding block is provided at the lower end of the sliding seat. The sliding block is helically connected to the threaded screw and is also slidably connected to the two guide rods. A connecting plate is fixedly connected to the upper end of the sliding seat. A reducer is fixedly installed at the upper end of the connecting plate. A motor is installed at the rear end of the reducer, and a support wheel is installed at the front end of the reducer.

[0006] For example, in at least one embodiment of the present disclosure, the support wheel installed at the front end of the reducer and the midpoint of the grinding wheel at the front end of the grinding mechanism are on the same horizontal line.

[0007] For example, at least one embodiment of the drill shank grinding fixture provided in this disclosure further includes: an adjusting vertical plate assembly is provided at the front end of the connecting plate, the adjusting vertical plate assembly includes a connecting frame, a nut, a movable slide, a U-shaped sliding plate, a threaded rod and a pointer, a nut is fixedly connected to the plate body at the left end of the connecting frame, a threaded rod is screwed into the nut, the right end of the threaded rod is movably connected to the movable slide, and a pointer is fixedly connected to the front end of the horizontal plate of the connecting frame, the pointer being flush with the rightmost vertex of the support wheel.

[0008] For example, in at least one embodiment of the present disclosure, a drill shank grinding fixture is provided, wherein the horizontal plate of the connecting frame is symmetrically provided with strip grooves, and the lower end of the movable slide is fixedly connected with a U-shaped sliding plate, and the two ends of the U-shaped sliding plate are respectively slidably disposed in the two strip grooves provided on the connecting frame.

[0009] For example, in at least one embodiment of the present disclosure, a drill shank grinding fixture is provided, wherein the horizontal plate of the connecting frame is symmetrically provided with strip grooves, and the lower end of the movable slide is fixedly connected with a U-shaped sliding plate, and the two ends of the U-shaped sliding plate are respectively slidably disposed in the two strip grooves provided on the connecting frame; For example, in at least one embodiment of the present disclosure, a drill shank grinding fixture is provided with a cylindrical protrusion at the left end of the movable slide, a fixing plate is fixedly connected to the right end of the movable slide, and a vertical plate is fixedly connected to the upper end of the fixing plate.

[0010] For example, in at least one embodiment of the present disclosure, a drill shank grinding fixture is provided with a limit block at the right end of the threaded rod. The limit block is movably connected to a cylindrical protrusion at the left end of the movable slide. The vertical plate on the movable slide is located between the grinding wheel and the support wheel at the front end of the grinding mechanism.

[0011] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, a support wheel is provided on one side of the grinding mechanism. The support wheel can support and fix the drill shank, replacing the traditional manual hand-held grinding. A threaded screw drives a sliding block to move a sliding seat, thereby adjusting the distance between the support wheel and the grinding wheel to accommodate drill shanks of different diameters. Under the transmission of a reducer, a motor drives the support wheel to rotate, achieving self-rotation grinding and uniform grinding of the drill shank surface. During the grinding process, it is ensured that the drill shank axis is parallel to the grinding wheel surface, improving the grinding efficiency and quality of the drill shank. The setting of pointers and scales facilitates precise adjustment of the distance between the support wheel and the grinding wheel, improving grinding accuracy and reducing grinding errors.

[0018] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0019] like Figures 1-6As shown, a drill shank grinding fixture according to an embodiment of this disclosure is illustrated, including a base 1, a baffle 2, a mounting base 3, a grinding mechanism 4, a slide rail 5, a slide groove 6, a guide rod 7, a threaded screw 8, a sliding seat 9, a connecting plate 10, a reducer 11, a support wheel 12, a motor 13, an adjusting vertical plate assembly 14, and a scale 15. The front and rear ends of the base 1 are fixedly connected to the baffle 2. The mounting base 3 is fixedly connected to the center of the upper end of the base 1. A motor support 401 is provided at the lower end of the grinding mechanism 4. The grinding mechanism 4 is fixedly mounted on the upper end of the mounting base 3 via the motor support 401. A slide rail 5 is fixedly connected to the upper end of the mounting base 3 in front of the grinding mechanism 4. The slide rail 5 has an opening... The slide rail frame 5 is provided with a slide groove 6. Two guide rods 7 are symmetrically arranged inside the slide rail frame 5. A threaded screw 8 is provided between the two guide rods 7. Both ends of the threaded screw 8 are movably connected to the slide rail frame 5. A rotating rod is provided at one end of the threaded screw 8 that extends out of the slide rail frame 5. A sliding seat 9 is slidably connected in the slide groove 6 of the slide rail frame 5. A sliding block 901 is provided at the lower end of the sliding seat 9. The sliding block 901 is helically connected to the threaded screw 8 and is also slidably connected to the two guide rods 7. A connecting plate 10 is fixedly connected to the upper end of the sliding seat 9. A reducer 11 is fixedly installed at the upper end of the connecting plate 10. A motor 13 is installed at the rear end of the reducer 11 and a support wheel 12 is installed at the front end of the reducer 11.

[0020] In this embodiment, by rotating the threaded screw 8, the sliding block 901 can move horizontally in the left and right directions along the guide rod 7. The movement of the sliding block 901 drives the sliding seat 9, which is fixedly connected to it, to slide synchronously in the slide groove 6, thereby driving the support wheel 12, which is fixedly installed on the sliding seat 9, to move. This adjusts the distance between the support wheel 12 and the grinding wheel of the grinding mechanism 4, thereby achieving the effect of supporting drill shanks of different diameters.

[0021] Under the transmission connection of reducer 11, the support wheel 12 and motor 13 can be driven to rotate by the rotation of the output shaft of motor 13. The rotation of support wheel 12 causes drill shank to rotate, thereby achieving the support effect on drill shank while realizing self-rotation grinding, so that the surface of drill shank is evenly ground and the grinding quality is guaranteed.

[0022] The support wheel 12 installed at the front end of the reducer 11 is on the same horizontal line as the midpoint of the grinding wheel at the front end of the grinding mechanism 4.

[0023] By aligning the support wheel 12 with the midpoint of the grinding wheel in the grinding mechanism 4 on the same horizontal line, the drill shank axis is kept parallel to the grinding wheel surface during the support grinding process, eliminating the need for manual hand-held operation and helping to ensure the grinding effect.

[0024] like Figures 5-6As shown, it illustrates a drill shank grinding fixture in one embodiment of the present disclosure, which further includes: an adjusting vertical plate assembly 14 disposed at the front end of the connecting plate 10, the adjusting vertical plate assembly 14 including a connecting frame 1401, a nut 1402, a movable slide 1403, a U-shaped sliding plate 1404, a threaded rod 1405 and a pointer 1406, the nut 1402 is fixedly connected to the plate body at the left end of the connecting frame 1401, the threaded rod 1405 is screwed inside the nut 1402, the right end of the threaded rod 1405 is movably connected to the movable slide 1403, and the pointer 1406 is fixedly connected to the front end of the horizontal plate of the connecting frame 1401, the pointer 1406 being flush with the rightmost vertex of the support wheel 12.

[0025] In this embodiment, since the pointer 1406 is fixedly connected to the connecting frame 1401, and the connecting frame 1401 is fixedly connected to the connecting plate 10, the pointer 1406 can move synchronously with the movement of the sliding seat 9. The pointer 1406 is aligned with the rightmost vertex of the support wheel 12, and the zero mark of the scale 15 is aligned with the leftmost vertex of the grinding wheel of the grinding mechanism 4. Therefore, by reading the scale pointed to by the pointer 1406, the distance between the support wheel 12 and the grinding wheel can be determined, which facilitates the precise adjustment of the distance between the support wheel 12 and the grinding wheel according to the diameter of the drill shank.

[0026] The horizontal plate of the connecting frame 1401 is symmetrically provided with strip grooves. The lower end of the movable slide 1403 is fixedly connected to a U-shaped slide plate 1404. The two ends of the U-shaped slide plate 1404 are respectively slidably arranged in the two strip grooves provided on the connecting frame 1401.

[0027] A cylindrical protrusion is provided on the left end of the movable slide 1403, and a fixed plate 14031 is fixedly connected to the right end of the movable slide 1403. A vertical plate 14032 is fixedly connected to the upper end of the fixed plate 14031.

[0028] The bent portions at both ends of the aforementioned U-shaped slide plate 1404 pass through the strip grooves opened on the connecting frame 1401 and are fixedly connected to the bottom of the movable slide block 1403, so that the movable slide block 1403 can slide horizontally along the cross plate of the connecting frame 1401. The position of the upright plate 14032 is adjusted by the movement of the movable slide block 1403, so that the upright plate 14032 is set in the area between the support wheel 12 and the grinding wheel, which serves to limit and support the grinding of the drill shank and prevent it from falling.

[0029] A limit block 14051 is provided at the right end of the threaded rod 1405. The limit block 14051 is movably connected to the cylindrical protrusion at the left end of the movable slide 1403. The vertical plate 14032 on the movable slide 1403 is located between the front grinding wheel and the support wheel 12 of the grinding mechanism 4.

[0030] Since the limiting block 14051 at the right end of the threaded rod 1405 is movably installed in the cylindrical protrusion at the left end of the movable slide 1403, by rotating the threaded rod 1405, the threaded rod 1405 can be screwed into or out of the nut 1402, thereby pushing and pulling the movable slide 1403. This allows the movable slide 1403 to move horizontally along the cross plate of the connecting frame 1401, thereby adjusting the setting position of the upright plate 14032 to adapt to the limiting use of drill shanks of different diameters.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
