Description

Deep hole bores crooked detection device of drill bit

Technical Field

The utility model relates to a crooked technical field that detects of drilling tool drill bit provides a crooked detection device of deep hole drill bit very much.

Background

Generally, a deep hole drill is adopted for processing medium-deep holes, the long diameter of the deep hole drill is large, and the drill is likely to bend after being polished for several times. The bent drill bit is easy to have the problems of cutter breakage, over-tolerance of aperture, over-tolerance of hole position degree and the like in the drilling process, so that the bent drill bit needs to be selected and cannot be continuously used for production.

The original detection method is to clamp the deep hole drill on the cutter handle and detect the drill bit by using optics. Because the clamping of the deep hole drill on the tool holder and the clamping of the tool holder on the tool setting gauge can inevitably generate errors, the bending state of the deep hole drill is easy to generate misjudgment under the influence of twice clamping errors.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a crooked detection device of deep hole brill drill bit.

The utility model discloses a realize like this, provide a crooked detection device of deep hole brill drill bit, including base, at least one V type slider and instrumentation, the base upper end is V type groove, and V type slider slides and matches in V type groove, and the stalk portion of deep hole brill drill bit is placed on V type slider, and instrumentation sets up the place ahead at the base.

Preferably, the bottom end of the V-shaped groove above the base is a sliding groove, the lower part of the V-shaped sliding block is a long sliding block, and the long sliding block is matched in the sliding groove at the bottom of the V-shaped groove.

More preferably, the number of the V-shaped sliders is 2.

Further preferably, still include the operation panel, the operation panel is a flat board, the base is fixed in the operation panel top, instrumentation passes through the setting of magnetic gauge stand on the operation panel, sets up the universal rod on the magnetic gauge stand, and instrumentation is cliied to the other end of universal rod.

Further preferably, the detection instrument is a dial indicator.

Compared with the prior art, the utility model has the advantages of:

the drill bit is detected by taking the drill bit handle part as a reference, so that the detection error can be reduced, and the detection efficiency is improved.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and embodiments:

FIG. 1 is a schematic structural view of the drill bit detection process of the present invention;

FIG. 2 is a schematic diagram showing the positional relationship between the base and the V-shaped slider.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, the utility model provides a crooked detection device of deep hole brill drill bit, including base 1, at least one V type slider 2 and instrumentation 3, the base 1 upper end is V type groove, and 2 sliding matches of V type slider are in V type groove, and the stalk portion of deep hole brill drill bit is placed on V type slider 2, and instrumentation 3 sets up the place ahead at base 1.

During detection, one end of a drill handle of the drill 6 is placed on the V-shaped sliding block 2, the position of a front-end drill bit to be detected is adjusted, the position of the drill handle is pressed by one hand (or the drill handle can be pressed by one or more pressing blocks), the detection instrument 3 is matched with a target detection position, the drill handle is rotated by the other hand, the drill bit rotates along with the drill handle, the reading of the detection instrument 3 is checked, and then the position of the drill handle is moved or the position of the V-shaped sliding block 2 is moved so as to detect the bending degree of the drill bit at different positions.

Referring to fig. 2, in order to limit the position of the V-shaped slider 2 during the sliding process, as an improvement of the technical solution, the bottom end of the V-shaped groove above the base 1 is a sliding groove, the lower portion of the V-shaped slider 2 is a long slider, and the long slider is matched in the sliding groove at the bottom of the V-shaped groove.

Preferably, the number of the V-shaped sliders 2 is 2. During measurement, one hand presses the drill handle on the slide block, and the other hand rotates the drill handle between the 2V-shaped slide blocks 2.

In order to conveniently set the detection instrument 3, as an improvement of the technical scheme, the detection instrument further comprises an operation table 4, the operation table 4 is a flat plate, the base 1 is fixed above the operation table 4, the detection instrument 3 is arranged on the operation table 4 through a magnetic meter seat 5, a universal rod is arranged on the magnetic meter seat 5, and the detection instrument 3 is clamped by the other end of the universal rod.

Preferably, for the convenience of detection, the detection instrument 3 is a dial indicator. When in detection, the jumps of the dial indicator are all less than 0.02mm, and the dial indicator is qualified.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
