Description

Technical Field

[0001] The utility model relates to the technical field of drill bit tooling, in particular to a caliper drill bit tooling. Background Art

[0002] Diameter gauges are widely used in various industries such as wires and cables, enameled wires, metal wires, PVC pipes, and medical devices. Laser diameter gauges are instruments that use lasers to measure the diameter of workpieces or materials. They are now widely used in industrial production. They include a transmitting end and a receiving end. The transmitting end and the receiving end of the prior art are integral, and the distance between the two is fixed. When measuring parts such as drill bits, there is no corresponding tooling to assist in fixing and rotating them. Ordinary tooling cannot stably fix and rotate them, and deviations are prone to occur.

[0003] A new type of caliper drill bit fixture is disclosed in Chinese patent CN201520412644.1. The knobs A, B, C and D of the new caliper drill bit fixture can be adjusted respectively to adapt to drill bits of different sizes and models. The drill bits are long and short, and the diameters are large and small. The various drill bits are matched by adjusting the knobs to ensure the accuracy of measurement. However, during the measurement process, the new caliper drill bit fixture pushes the rotating drill bit to feed through the caliper to complete the measurement, which affects the stability of the caliper rotation and is likely to affect the measurement accuracy. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a caliper drill bit tooling to effectively solve the deficiencies of the prior art.

[0005] The objective of the utility model is achieved through the following technical scheme: a caliper drill bit tooling, comprising a base plate, a fixed frame fixedly connected to one side of the top of the base plate, a motor fixedly connected to the inside of the fixed frame, an assembly frame fixedly connected to the output end of the motor, a first slide rail fixedly connected to one side of the top of the base plate, a laser caliper gauge slidably connected to the inner side of the first slide rail, a second slide rail fixedly connected to the middle of the top of the base plate, and a support seat provided on the top of the second slide rail.

[0006] Optionally, the assembly frame is located inside the fixed frame, the assembly frame is rotatably connected to the fixed frame, the assembly groove inside the assembly frame has a stepped cross-section, and the diameter inside the assembly frame increases sequentially from inside to outside.

[0007] The above technical solution is adopted: by setting a motor-driven assembly frame inside the fixed frame, the assembly end of the drill bit is inserted into the assembly frame, and the internal stepped grooves can adapt to the assembly ends of drill bits with different diameters, thereby completing the assembly and fixation of drill bits with different diameters, and the motor drives the assembly frame and the drill bit to rotate, so that the diameter gauge measures the diameter of the rotating drill bit.

[0008] Optionally, a plurality of friction rings are fixedly connected to the interior of the assembly frame, and the friction rings are all arranged on the inner side of the steps inside the assembly frame. The friction rings are made of rubber sponge, and the cross-sectional shape of the friction rings is a triangle.

[0009] The above technical solution is adopted: by setting a friction ring at the internal step of the assembly frame, when the drill bit is installed in a groove of corresponding diameter, pressing inward can cooperate with the friction ring, so that the friction ring clamps the assembly end of the drill bit inward to further strengthen the assembly, thereby improving the stability of the assembly between the drill bit and the assembly frame.

[0010] Optionally, the first slide rail and the second slide rail are both electric slide rails, and the vertical distance from the support seat to the assembly frame is always unequal to the vertical distance from the laser diameter gauge to the assembly frame.

[0011] The above technical solution is adopted: by setting the first slide rail and the second slide rail as electric slide rails, so that they can control the sliding of the laser diameter gauge and the support seat, and limit the distances between the two and the assembly frame to always be unequal. When the support seat is located between the laser diameter gauge and affects the detection of the diameter gauge, the support seat can automatically slide and adjust the position to avoid the situation where the support seat affects the detection of the laser diameter gauge.

[0012] Optionally, a sliding plate is slidably connected to the top of the second slide rail, an electric push rod is fixedly connected to the top of the sliding plate, an output end of the electric push rod is fixedly connected to the bottom of the support seat, and a telescopic stroke of the electric push rod is greater than half of the maximum inner diameter of the assembly frame.

[0013] The above technical solution is adopted: by arranging an electric push rod between the sliding plate and the support seat, the height of the support seat can be adjusted. When the drill bit is assembled and fixed with the assembly frame, the height of the support seat is adjusted so that it supports one end of the drill bit from the bottom, thereby improving the stability of the drill bit during rotation, thereby improving the accuracy of the side diameter of the drill bit during rotation.

[0014] Optionally, the top of the support seat is V-shaped, and the friction coefficient between the support seat and the drill bit being tested is less than 0.5.

[0015] By adopting the above technical solution, a V-shaped support seat is provided, which can support the drill bit and limit its position at the same time, and limiting the friction coefficient can reduce the wear of the support seat during the rotation of the drill bit.

[0016] The utility model has the following advantages:

[0017] 1. The caliper drill bit tooling provides a motor-driven assembly frame inside a fixed frame, and inserts the assembly end of the drill bit into the assembly frame. The internal stepped slots can adapt to the assembly ends of drill bits with different diameters, thereby completing the assembly and fixation of drill bits with different diameters. The motor drives the assembly frame and the drill bit to rotate, so that the caliper measures the diameter of the rotating drill bit. A friction ring is provided at the internal step of the assembly frame, and when the drill bit is installed in a groove of a corresponding diameter, inward pressing can cooperate with the friction ring, so that the friction ring clamps the assembly end of the drill bit inward to further reinforce the assembly, thereby improving the stability of the assembly of the drill bit and the assembly frame.

[0018] 2. The diameter gauge drill bit tooling, by setting the first slide rail and the second slide rail as electric slide rails, can control the sliding of the laser diameter gauge and the support seat, and limit the distances between the two and the assembly frame to always be unequal. When the support seat is located between the laser diameter gauge and affects the detection of the diameter gauge, the support seat can automatically slide and adjust the position to avoid the situation where the support seat affects the detection of the laser diameter gauge.

[0019] 3. The diameter gauge drill bit tooling can adjust the height of the support seat by arranging an electric push rod between the sliding plate and the support seat. After the drill bit is assembled and fixed with the assembly frame, the height of the support seat is adjusted to support one end of the drill bit from the bottom, thereby improving the stability of the drill bit during rotation, thereby improving the accuracy of the side diameter of the drill bit during rotation. By arranging a V-shaped support seat, the drill bit can be supported and limited at the same time, and limiting the friction coefficient can reduce the wear of the support seat during the rotation of the drill bit.

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figures 1 to 6 As shown, a caliper drill bit tooling includes a base plate 1, a fixed frame 2 is fixedly connected to one side of the top of the base plate 1, a motor 3 is fixedly connected inside the fixed frame 2, an assembly frame 4 is fixedly connected to the output end of the motor 3, a first slide rail 5 is fixedly connected to one side of the top of the base plate 1, a laser caliper 6 is slidably connected to the inner side of the first slide rail 5, a second slide rail 7 is fixedly connected to the middle of the top of the base plate 1, and a support seat 8 is arranged on the top of the second slide rail 7.

[0029] Embodiment 1: The assembly frame 4 is located inside the fixed frame 2, and the assembly frame 4 is rotatably connected to the fixed frame 2. The cross-section of the assembly groove inside the assembly frame 4 is stepped, and the diameter inside the assembly frame 4 increases from the inside to the outside. By setting an assembly frame 4 driven by a motor 3 inside the fixed frame 2, the assembly end of the drill bit is inserted into the assembly frame 4, and the internal stepped grooves can adapt to the assembly ends of drill bits of different diameters, thereby completing the assembly and fixation of drill bits of different diameters. The motor 3 drives the assembly frame 4 and the drill bit to rotate, so that the diameter gauge measures the diameter of the rotating drill bit.

[0030] Embodiment 2: A plurality of friction rings 9 are fixedly connected to the inside of the assembly frame 4. The friction rings 9 are all arranged on the inner side of the internal steps of the assembly frame 4. The friction rings 9 are made of rubber sponge and have a triangular cross-sectional shape. By arranging the friction rings 9 at the internal steps of the assembly frame 4 and then inserting the drill bit into a groove of a corresponding diameter, pressing inwards can cooperate with the friction rings 9, so that the friction rings 9 clamp the assembly end of the drill bit inwards to further reinforce the assembly, thereby improving the stability of the assembly between the drill bit and the assembly frame 4.

[0031] Embodiment 3: The first slide rail 5 and the second slide rail 7 are both electric slide rails, and the vertical distance from the support seat 8 to the assembly frame 4 is always unequal to the vertical distance from the laser diameter gauge 6 to the assembly frame 4. By setting the first slide rail 5 and the second slide rail 7 as electric slide rails, it is possible to control the sliding of the laser diameter gauge 6 and the support seat 8, and limit the distances from the two to the assembly frame 4 to always be unequal. Then, when the support seat 8 is located between the laser diameter gauge 6 and affects the detection of the diameter gauge, the support seat 8 can automatically slide to adjust its position to avoid the situation where the support seat 8 affects the detection of the laser diameter gauge 6.

[0032] Embodiment 4: The top of the second slide rail 7 is slidably connected to a sliding plate 10, and the top of the sliding plate 10 is fixedly connected to an electric push rod 11, and the output end of the electric push rod 11 is fixedly connected to the bottom of the support seat 8, and the telescopic stroke of the electric push rod 11 is greater than half of the maximum inner diameter of the assembly frame 4. By arranging the electric push rod 11 between the sliding plate 10 and the support seat 8, the height of the support seat 8 can be adjusted. When the drill bit is assembled and fixed to the assembly frame 4, the height of the support seat 8 is adjusted to support one end of the drill bit from the bottom, thereby improving the stability of the drill bit during rotation, thereby improving the accuracy of the side diameter of the drill bit during rotation.

[0033] Embodiment 5: The top of the support seat 8 is V-shaped, and the friction coefficient between the support seat 8 and the drill bit being tested is less than 0.5. By setting a V-shaped support seat 8, the drill bit can be supported and limited at the same time. Limiting the friction coefficient can reduce the wear of the support seat 8 during the rotation of the drill bit.

[0034] The working principle of the utility model is as follows:

[0035] S1, an assembly frame 4 driven by a motor 3 is arranged inside the fixed frame 2, and the assembly end of the drill bit is inserted into the assembly frame 4. The stepped groove inside can adapt to the assembly ends of drill bits with different diameters, so as to complete the assembly and fixation of drill bits with different diameters, and the assembly frame 4 and the drill bit are driven by the motor 3 to rotate, so that the diameter gauge measures the diameter of the rotating drill bit;

[0036] S2. An electric push rod 11 is arranged between the sliding plate 10 and the support seat 8 so that the height of the support seat 8 can be adjusted. After the drill bit is assembled and fixed with the assembly frame 4, the height of the support seat 8 is adjusted so that it supports one end of the drill bit from the bottom, thereby improving the stability of the drill bit during rotation, thereby improving the accuracy of the side diameter of the drill bit during rotation.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. The caliper drill bit tooling is provided with an assembly frame 4 driven by a motor 3 inside a fixed frame 2, and the assembly end of the drill bit is inserted into the assembly frame 4. The internal stepped grooves can adapt to the assembly ends of drill bits with different diameters, so as to complete the assembly and fixation of drill bits with different diameters. The motor 3 drives the assembly frame 4 and the drill bit to rotate, so that the caliper measures the diameter of the rotating drill bit. A friction ring 9 is provided at the internal step of the assembly frame 4, and when the drill bit is installed in a groove of a corresponding diameter, it can be pressed inward to cooperate with the friction ring 9, so that the friction ring 9 clamps the assembly end of the drill bit inward to further reinforce the assembly, thereby improving the stability of the assembly of the drill bit and the assembly frame 4.

[0039] 2. The caliper drill bit tooling, by setting the first slide rail 5 and the second slide rail 7 as electric slide rails, can control the sliding of the laser diameter gauge 6 and the support seat 8, and limit the distances between the two and the assembly frame 4 to always be unequal. When the support seat 8 is located between the laser diameter gauge 6 and affects the detection of the diameter gauge, the support seat 8 can automatically slide and adjust its position to avoid the situation where the support seat 8 affects the detection of the laser diameter gauge 6.

[0040] 3. The caliper drill bit tooling, by setting an electric push rod 11 between the sliding plate 10 and the support seat 8, enables the height of the support seat 8 to be adjusted. When the drill bit is assembled and fixed with the assembly frame 4, the height of the support seat 8 is adjusted so that it supports one end of the drill bit from the bottom, thereby improving the stability of the drill bit during rotation, thereby improving the accuracy of the side diameter of the drill bit during rotation. By setting a V-shaped support seat 8, the drill bit can be supported and limited at the same time, and limiting the friction coefficient can reduce the wear of the support seat 8 during the rotation of the drill bit.
