Description

Technical Field

[0001] This utility model belongs to the field of fixed tooling technology, and in particular relates to a fixed tooling for measuring PCB micro drill bits. Background Technology

[0002] Drill bits with a diameter of 3.175mm or less are called micro drills, hereinafter referred to as micro drills. Currently, manufacturers of carbide micro drills for PCBs use fixed-position shims to measure the cutting diameter of micro drills. The disadvantage of this method is that it cannot accurately locate the cutting edge, causing scrap due to cutting diameter deviations in subsequent manufacturing processes. Moreover, existing fixtures can only fix one micro drill bit at a time, making it impossible to fix multiple micro drill bits simultaneously for measurement. Furthermore, adjusting fixed-position micro drill bits is cumbersome, requiring component replacement, resulting in time-consuming and inefficient component replacement operations. Utility Model Content

[0003] The purpose of this utility model is to provide a fixing fixture for measuring PCB micro drill bits. By sliding a strip slider on a U-shaped slide table, each fixing mechanism is pushed to the measurement position to complete the purpose of measuring multiple drill bits at once. It can also rotate the fixing mechanism to place the required drill bit fixing unit in the measurement position, realizing the requirement of quickly adjusting the fixing of different models of micro drill bits. This solves the problems of existing fixtures that can only measure one micro drill bit at a time, have low measurement efficiency, and are troublesome to adjust and fix different models of micro drill bit components.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a fixture for measuring micro drill bits in PCBs, comprising a U-shaped slide, a strip slider, and a fixing mechanism. Two limiting slide rods are provided on the vertical platforms at both ends of the U-shaped slide. The strip slider is slidably fitted onto the two limiting slide rods. A displacement motor is embedded in one of the vertical platforms of the U-shaped slide 1. A displacement lead screw is connected to the rotating shaft of the displacement motor and spirally passes through the strip slider. Multiple fixing slots are provided at equal intervals on the top of the strip slider. A fixing mechanism is installed in each fixing slot. A rotation drive assembly is correspondingly provided on the outer wall of each fixing slot. A fixing clamping assembly is installed on the side wall at the slot opening of each fixing slot. Multiple drill bit fixing units are provided on the fixing mechanism. The rotation drive assembly is used to rotate each drill bit fixing unit on the fixing mechanism to the position of the fixing clamping assembly.

[0006] The present invention is further configured such that the distance between the two vertical platforms of the U-shaped slide is twice the length of the strip slider.

[0007] The present invention is further configured such that the fixing mechanism includes a turntable, a clamping assembly and a rubber sleeve. Rotating rods are symmetrically arranged on both sides of the turntable. Four clamping platforms are evenly distributed on the circumference sidewall of the turntable. Rubber grooves are provided on the clamping platforms. Rubber sleeves are inserted into the rubber grooves. Two slots are symmetrically arranged on both sides of the turntable at the clamping platform positions. The clamping assembly is installed in the slot.

[0008] The present invention is further configured such that the clamping assembly includes a T-shaped extrusion plate 62, the front end of the T-shaped extrusion plate is provided with an arc-shaped opening, and two return springs are symmetrically provided on the rear side plate of the T-shaped extrusion plate. The return springs are embedded in the turntable and the T-shaped extrusion plate is inserted into the slot so that the arc-shaped opening contacts the rubber sleeve.

[0009] The present invention is further configured such that the fixed clamping assembly includes two oppositely arranged extrusion cylinders, and an extrusion plate is fixed on the telescopic shaft of the extrusion cylinder, the extrusion plate being directly opposite the T-shaped extrusion plate.

[0010] The present invention is further configured such that the rotation drive assembly includes a motor frame and a brake servo motor, the motor frame is fixed on the outer wall of the strip slider, and the brake servo motor is mounted on the motor frame and the motor shaft is connected to the rotating rod.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model uses a fixed-distance displacement bar slider to push each fixed mechanism to the measurement position. By pushing the bar slider, multiple fixed mechanisms are sequentially sent to the measurement position, and multiple PCB micro drill bits are measured at one time, thereby achieving the purpose of measuring multiple PCB micro drill bits at one time and improving efficiency.

[0013] 2. This utility model uses a rotating turntable to move the required drill bit fixing unit to the fixed clamping component position. Different drill bit fixing units can clamp and fix different models of PCB micro drill bits, thereby realizing the adjustment and switching of fixing different models of PCB micro drill bits without replacing the clamping and fixing components, making switching convenient.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6This utility model relates to a fixture for measuring micro drill bits in PCBs, comprising a U-shaped slide 1, a strip slider 4, and a fixing mechanism 6. Two limiting slide rods 3 are provided on the vertical platforms at both ends of the U-shaped slide 1. The strip slider 4 is slidably fitted onto the two limiting slide rods 3. A displacement motor 2 is embedded in one of the vertical platforms of the U-shaped slide 1. A displacement lead screw 21 is connected to the rotating shaft of the displacement motor 2, and the displacement lead screw 21 spirally passes through the strip slider 4. Multiple fixing mounting slots 42 are provided at equal intervals on the top of the strip slider 4. The fixing mechanism 6 is installed within each fixing mounting slot 42. A rotation drive assembly is correspondingly provided on the outer wall of each fixing mounting slot 42. A fixing clamping assembly is installed on the side wall at the slot opening of the fixing mounting slot 42. The fixing mechanism 6 is provided with multiple drill bit fixing units. The rotation drive assembly is used to rotate each drill bit fixing unit on the fixing mechanism 6 to the position of the fixing clamping assembly.

[0026] The fixing mechanism 6 can rotate within the fixing mounting slot 42 to adjust the orientation of different drill bit fixing units and position them within the fixing clamping assembly. When a PCB micro drill bit is inserted into the drill bit fixing unit, the fixing clamping assembly clamps and fixes the PCB micro drill bit. When measurement is required, the strip slider 4 is pushed on the U-shaped slide table 1, causing each fixing mechanism 6 to be pushed to the measurement position for measurement of the PCB micro drill bit on each fixing mechanism 6. After measurement, the entire strip slider 4 is pulled back to its initial position. A new PCB micro drill bit is then replaced and re-fixed.

[0027] The U-shaped slide 1 has a spacing between its two vertical platforms that is twice the length of the strip slider 4. This ensures that the strip slider 4 is fully extended from its initial position.

[0028] The fixing mechanism includes a turntable 61, a clamping assembly, and a rubber sleeve 63. Rotating rods 64 are symmetrically arranged on both sides of the turntable 61. Four clamping platforms 611 are evenly distributed on the circumference of the turntable 61. Each clamping platform 611 is provided with a rubber groove 613, and a rubber sleeve 63 is inserted into the rubber groove 613. Two slots 612 are symmetrically arranged on both sides of the turntable at the position of the clamping platform 611, and the clamping assembly is installed in the slot 612.

[0029] The rubber sleeve 63 is replaceable as needed to accommodate more PCB micro drill bit holder positions. When the PCB micro drill bit holder is inserted into the rubber sleeve 63, it is movable. At this time, the clamping component is activated and the clamping component is fixed to hold the rubber sleeve 63 so as to clamp and fix the PCB micro drill bit in place.

[0030] The clamping assembly includes a T-shaped extrusion plate 62. The front end of the T-shaped extrusion plate 62 is provided with an arc-shaped opening. Two return springs 621 are symmetrically provided on the rear side of the T-shaped extrusion plate 62. The return springs 621 are embedded in the turntable 61 and the T-shaped extrusion plate 62 is inserted into the slot 612 so that the arc-shaped opening contacts the rubber sleeve 63.

[0031] When the T-shaped extrusion plate 62 is pushed into the slot 612, the arc-shaped opening tightly grips the rubber sleeve 63, causing the rubber sleeve 63 to compress and secure the PCB micro drill bit. When the compression is released, the clamping assembly is released, and the return spring 621 pushes the T-shaped extrusion plate 62 back, releasing the clamp. This allows the PCB micro drill bit to be removed by a robotic arm or manually.

[0032] The fixed clamping assembly includes two opposing extrusion cylinders 5, and an extrusion plate is fixed on the telescopic shaft of the extrusion cylinder 5, with the extrusion plate facing the T-shaped extrusion plate 62.

[0033] Two extrusion cylinders 5 start simultaneously, pushing the extrusion plate 62 out and extruding it.

[0034] The rotation drive assembly includes a motor frame 41 and a brake servo motor 411. The motor frame 41 is fixed on the outer wall of the strip slider 4, and the brake servo motor 411 is mounted on the motor frame 41 and the motor shaft is connected to the rotating rod 64.

[0035] The brake servo motor 411 can rotate 90° each time, causing the rotating rod 64 to rotate 90° and the turntable 61 to rotate 90°, thus switching the drill bit fixing unit to change the rubber sleeve 63. Different rubber sleeves 63 can fit different models of PCB micro drill bits. If the four rubber sleeves 63 cannot meet the needs of the PCB micro drill bits, the rubber sleeves 63 can be replaced to adapt and hold the PCB micro drill bits.
