Description

Technical Field

[0001] The utility model relates to the technical field of drill bit processing, in particular to an infrared light spot mechanism of drill bit processing detection equipment. Background Art

[0002] After the drill bit is processed, it is necessary to detect the processing quality of the drill bit, such as detecting the roundness of the drill bit. The utility model patent with publication number CN207171660U discloses a technical solution for detecting the roundness of the drill bit by measuring the infrared imaging spot. It can accurately detect the roundness of the drill bit through multi-point measurement, but it still has some shortcomings:

[0003] Its infrared light spot mechanism relies on the expansion and contraction of a laterally arranged spring to achieve the positioning of the drill bit. However, the sizes of drill bits actually detected vary. Since the infrared diode is arranged vertically, the drill bit may push the infrared diode downward when it is advanced from top to bottom, that is, the laterally arranged spring produces an inclined deformation. At this time, multiple infrared diodes are not on the same horizontal circumference. In this case, there is a certain error in the measured roundness. Utility Model Content

[0004] In order to solve the deficiencies in the prior art, the utility model provides an infrared light spot mechanism of a drill bit processing and detection device. The infrared light spot mechanism of the drill bit processing and detection device is provided with a rotatable contact head, so that when the drill bit initially contacts the contact head, it can apply pressure to the telescopic column through the rotatable contact head, so that the telescopic column moves in a straight line under the limit of the bottom cylinder. The contact head rotates itself to fit the drill bit during the position change process. Each contact head can always keep in the same horizontal circumference to fit the drill bit, thereby ensuring the accuracy of the measurement result and being more adaptable to drill bits of different sizes.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides an infrared light spot mechanism of a drill bit processing detection device, comprising a positioning ring, wherein a plurality of positioners are arranged around the inner wall of the positioning ring;

[0007] The positioner comprises a bottom tube, a telescopic column is inserted into the bottom tube, a spring is arranged between the bottom of the telescopic column and the inner cavity of the bottom tube, and one end of the telescopic column away from the bottom tube is rotatably connected to a contact head;

[0008] An infrared diode is arranged at one end of the contact head.

[0009] In the infrared light spot mechanism of the drill processing and detection equipment of the utility model, the telescopic column is in the highest position due to the elastic force of the spring in a natural state. At this time, the space for multiple positioners to close is small. When drill bits of different sizes enter, they first contact the contact head. Since the contact head is rotatable, the downward force applied by the drill bit will drive the contact head to fit the surface of the drill bit and the component force can press the telescopic column to retract. Since the telescopic column and the bottom cylinder are both rigid, the directions of extension and retraction of each positioner are consistent, which ensures the stability of the movement direction and position of each contact head. In this case, the light emitted by the infrared diode on the contact head which is close to the drill bit and on the same horizontal circumference can reflect the accurate roundness of the drill bit after detection.

[0010] The infrared light spot mechanism of the drill bit processing and detection equipment of the utility model is provided with a rotatable contact head, so that when the drill bit initially contacts the contact head, pressure can be applied to the telescopic column through the rotatable contact head, so that the telescopic column moves in a straight line under the limit of the bottom cylinder, and the contact head rotates automatically in the process of position change to fit the drill bit, and each contact head can always keep in the same horizontal circumference to fit the drill bit, thereby ensuring the accuracy of the measurement result and being more adaptable to drill bits of different sizes.

[0011] In a further technical solution, a torsion spring is provided at the hinge between the contact head and the telescopic column.

[0012] The setting of the torsion spring enables the angle of the contact head to be controlled in a natural state, that is, it can maintain an inclined posture in a natural state, so that its angle can be adjusted smoothly when it contacts the drill bit.

[0013] In a further technical solution, the base tube and the telescopic column are both arranged to be inclined relative to the vertical direction, and the inclination direction is that the top thereof is inclined toward the central axis of the positioning ring.

[0014] The bottom cylinder and the telescopic column are both inclined so that when the contact head is subjected to vertical pressure, its component force can naturally drive the telescopic column to retract, and the movement process is smoother.

[0015] In a further technical solution, a mounting seat is provided on the inner ring surface of the positioning ring, and the mounting seat has an inclined surface inclined upward toward the center axis of the positioning ring, and the positioner is arranged on the inclined surface.

[0016] The setting of the mounting seat facilitates the installation and positioning of the positioner, and the angles are uniform.

[0017] The beneficial effects are:

[0018] 1. The infrared light spot mechanism of the drill bit processing and detection equipment of the utility model is provided with a rotatable contact head, so that when the drill bit initially contacts the contact head, it can apply pressure to the telescopic column through the rotatable contact head, so that the telescopic column moves in a straight line under the limit of the bottom cylinder. The contact head rotates automatically in the process of position change to fit the drill bit. Each contact head can always keep in the same horizontal circumference to fit the drill bit, thereby ensuring the accuracy of the measurement result and being more adaptable to drill bits of different sizes.

[0019] 2. The setting of the torsion spring enables the angle of the contact head to be controlled in the natural state, that is, it can maintain an inclined posture in the natural state, so that its angle can be adjusted smoothly when it contacts the drill bit.

[0020] 3. The bottom cylinder and telescopic column are both tilted so that when the contact head is subjected to vertical pressure, its force component can naturally drive the telescopic column to retract, making the movement process smoother.

[0021] 4. The setting of the mounting seat facilitates the installation and positioning of the positioner, and the angle is unified. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example:

[0028] An infrared light spot mechanism of a drill bit processing detection device, such as Figure 1 As shown, it includes a positioning ring 10, and a plurality of positioners 30 are arranged around the inner wall of the positioning ring 10. Figure 1 For the convenience of demonstration, two locators 30 are shown;

[0029] like Figure 3As shown, the positioner 30 includes a bottom cylinder 31, a telescopic column 32 is inserted into the bottom cylinder 31, a spring is arranged between the bottom of the telescopic column 32 and the inner cavity of the bottom cylinder 31, and one end of the telescopic column 32 away from the bottom cylinder 31 is rotatably connected to a contact head 33;

[0030] An infrared diode 34 is disposed at one end of the contact head 33 .

[0031] In the infrared light spot mechanism of the drill processing detection device of the utility model, the telescopic column 32 is at the highest position due to the elastic force of the spring in the natural state. At this time, the space where the multiple positioners 30 are closed is small. When drills of different sizes enter, they first contact the contact head 33. Since the contact head 33 is rotatable, the downward force applied by the drill will drive the contact head 33 to fit the surface of the drill and the component force can press the telescopic column 32 to retract. Figure 2 As shown, since the telescopic column 32 and the bottom cylinder 31 are both rigid, the directions of extension and retraction of each positioner 30 are consistent, which ensures the stability of the movement direction and position of each contact head 33. In this case, the light emitted by the infrared diode 34 on the contact head 33 which is close to the drill bit and on the same horizontal circumference can reflect the accurate roundness of the drill bit after detection.

[0032] It is understandable that the principle of detecting drill bit roundness by measuring infrared imaging spot is a prior art. This embodiment is aimed at improving the positioning structure of the infrared diode 34, and other structures of the detection principle are not described in detail here.

[0033] The infrared light spot mechanism of the drill bit processing and detection equipment of the present invention is provided with a rotatable contact head 33, so that when the drill bit initially contacts the contact head 33, pressure can be applied to the telescopic column 32 through the rotatable contact head 33, so that the telescopic column 32 moves in a straight line under the limit of the bottom cylinder 31, and the contact head 33 rotates itself to fit the drill bit during the position change process, and each contact head 33 can always keep in the same horizontal circumference to fit the drill bit, thereby ensuring the accuracy of the measurement result and being more adaptable to drill bits of different sizes.

[0034] In another embodiment, a torsion spring is provided at the hinge between the contact head 33 and the telescopic column 32 .

[0035] The provision of the torsion spring enables the angle of the contact head 33 to be controlled in a natural state, that is, it can maintain an inclined posture in a natural state, so that its angle can be adjusted smoothly when in contact with the drill bit.

[0036] In another embodiment, if Figure 1 As shown, the bottom cylinder 31 and the telescopic column 32 are both arranged to be inclined relative to the vertical direction, and the inclined direction is that the top thereof is inclined toward the central axis of the positioning ring 10 .

[0037] The bottom cylinder 31 and the telescopic column 32 are both arranged obliquely, so that when the contact head 33 is subjected to vertical pressure, its component force can naturally drive the telescopic column 32 to retract, and the movement process is more stable.

[0038] In another embodiment, if Figure 1 As shown, a mounting seat 20 is provided on the inner ring surface of the positioning ring 10. The mounting seat 20 has an inclined surface inclined upward toward the center axis of the positioning ring 10. The locator 30 is arranged on the inclined surface.

[0039] The installation of the mounting seat 20 facilitates the installation and positioning of the positioner 30, and the angles thereof are uniform.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
