Description

Technical Field

[0001] This utility model relates to the technical field of drilling positioning devices, and in particular to a drilling positioning device for machining the mirror body of a die-casting part. Background Technology

[0002] Die-cast lens bodies refer to the lens bodies of optical instruments manufactured through the die-casting process (used to fix lens groups, adjust focal length, and connect the frame structure of the instrument body). During the processing of die-cast lens bodies, drilling operations are required using a horizontal machining center. Drilling is one of the common processing methods of horizontal machining centers. Drilling is a basic method of hole processing. After the lens body is clamped and positioned by the positioning device of the horizontal machining center, drilling operations can be performed by a high-speed rotating tool.

[0003] The positioning devices used in the drilling of existing die-cast mirror bodies do not have the function of limiting the clamping force. Die-cast mirror bodies are generally frame structures. If a large clamping and positioning force is applied, the mirror body may twist or deform. If the clamping and positioning force is small, the mirror body is prone to displacement during the processing, resulting in deviations in the drilling position. The devices are not flexible or stable and are not very practical. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please refer to Figures 1 to 6 Example 1:

[0029] This utility model proposes a drilling positioning device for machining the mirror body of a die-casting part, including: a mounting component 1 and a positioning component; the mounting component 1 includes a mounting base 101, a fixed block 102, a drive motor 103 and a drive rod 104, the fixed block 102 is fixedly mounted on the top of the mounting base 101, and the drive motor 103 is fixedly mounted on the side of the mounting base 101, the drive rod 104 is rotatably connected to the inside of the mounting base 101, and one end of the drive rod 104 is connected to the rotating shaft of the drive motor 103; the positioning component consists of a moving mechanism 2 and an adjusting mechanism 3.

[0030] The moving mechanism 2 includes a moving block 201, a positioning block 202, a transmission block 203, and a positioning disk 204. The moving block 201 is inserted into the interior of the mounting base 101, and the positioning block 202 is rotatably connected to the interior of the moving block 201. The transmission block 203 is inserted into the interior of the positioning block 202, and the positioning disk 204 is inserted into the interior of the positioning block 202. The adjusting mechanism 3 includes an adjusting screw 301 and a retainer 302. The adjusting screw 301 is rotatably connected to the interior of the moving block 201, and the retainer 302 is inserted into the interior of the moving block 201. The adjusting screw 301 is screwed to the top of the retainer 302 via a threaded rod.

[0031] The mounting base 101 has a threaded positioning rod 1011 inside, which passes through the interior of the moving block 201. The threaded positioning rod 1011 and the external thread of the positioning block 202 are engaged. During use, the die-cast mirror body can be positioned during drilling by the clamping action of the fixed block 102 and the moving block 201. Positioning is quick and convenient. After the die-cast mirror body is placed between the fixed block 102 and the moving block 201, the drive motor 103 is controlled to rotate forward (with the rotation direction of the positioning block 202 when the moving block 201 moves toward the fixed block 102 as the positive direction). The drive motor 103 can drive the drive rod 104 to rotate forward. The middle section of the drive rod 104 has a regular polygonal cross-section, and the transmission block 203 has a synchronous groove 2032 inside. The part of the regular polygonal rod of the drive rod 104 is inserted into the synchronous groove 2032, and the rod body of the drive rod 104 passes through the moving block 201. Inside the moving block 201, positioning block 202, and positioning disk 204, the drive rod 104 can drive the transmission block 203 to rotate through the synchronous groove 2032 when rotating forward. Under the action of the torsion top spring 2042, when the transmission block 203 rotates, the inclined sides of the two sets of transmission gear rings 2031 can abut against each other and rub against each other, thereby driving the positioning block 202 to rotate forward synchronously. When the positioning block 202 rotates forward, it can drive the moving block 201 to move closer to the fixed block 102 through the threaded engagement with the threaded positioning rod 1011, thereby realizing the clamping operation of the mirror body. When it is necessary to release the mirror body, it is only necessary to control the shaft of the drive motor 103 to reverse. At this time, the transmission block 203 will reverse synchronously. Under the snapping action between the straight sides of the two sets of transmission gear rings 2031, the positioning block 202 can reverse synchronously, thereby causing the moving block 201 to move away from the fixed block 102, realizing the operation of releasing the mirror body. It is convenient and flexible to use.

[0032] The positioning disk 204 has a torsion spring 2042 on its side, with both ends of the torsion spring 2042 abutting against the side of the positioning disk 204 and the side of the transmission block 203, respectively. Both the transmission block 203 and the positioning block 202 have transmission gear rings 2031 on their opposing sides, and the cross-sectional shape of a single tooth of the transmission gear ring 2031 is a right-angled triangle. Under the action of the torsion spring 2042, the transmission gear rings 2031 of the transmission block 203 and the positioning block 202 are interlocked. During use, the positioning assembly has the function of limiting the maximum clamping force. When the clamping force is less than the maximum clamping force, the torsion spring 2042 can stably maintain the two sets of transmission gear rings 2031 between their hypotenuses. The opposing friction transmission action means that the positioning block 202 and the transmission block 203 will rotate synchronously. When the clamping force is greater than the maximum clamping force, the increase in clamping resistance makes the torsion top spring 2042 unable to maintain the opposing friction transmission action between the inclined sides of the two sets of transmission gear rings 2031. After that, even if the transmission block 203 continues to rotate in the forward direction, the inclined sides of the gear teeth of the two sets of transmission gear rings 2031 can squeeze each other, causing the transmission block 203 to move away from the positioning block 202 and compress the torsion top spring 2042. As a result, the transmission block 203 can no longer transmit the positioning block 202. The transmission block 203 will rotate on its own, avoiding excessive movement of the moving block 201 and damage to the mirror body, thus ensuring stable use.

[0033] The positioning disk 204 has a retaining block 2041 on its outer side, and the block body of the retaining block 2041 passes through the interior of the positioning block 202. The block body of the retaining block 2041 passing through the interior of the positioning block 202 is rotatably connected to the interior of the retainer 302. In use, the maximum clamping force value of the positioning component can be freely adjusted. When the adjusting screw 301 is rotated, the adjusting screw 301 can drive the retainer 302 to move through the screw thread. When the retainer 302 moves, it can drive the positioning disk 204 to move inside the positioning block 202 through the retaining block 2041 to change the use position. The change of the use position of the positioning disk 204 changes the clamping resistance required to trigger the limit function, that is, the maximum clamping limit force. The adjustment is convenient and flexible, and the use is stable.

[0034] The working principle of this embodiment is as follows: Based on the material and specifications of the die-cast mirror body, the maximum clamping force of the positioning component is adjusted. When the adjusting screw 301 is rotated, the adjusting screw 301 can drive the retainer 302 to move through the screw thread. When the retainer 302 moves, it can drive the positioning disk 204 to move inside the positioning block 202 through the retaining block 2041, changing its usage position. The change in the usage position of the positioning disk 204 changes the clamping resistance required to trigger the limiting function, i.e., the maximum clamping limiting force. Under the clamping action of the fixed block 102 and the moving block 201, the die-cast mirror body can be positioned during drilling. Quickly and easily, after placing the die-cast mirror body between the fixed block 102 and the moving block 201, control the drive motor 103 to rotate clockwise (taking the rotation direction of the positioning block 202 when the moving block 201 moves towards the fixed block 102 as the positive direction). The drive motor 103 can drive the drive rod 104 to rotate clockwise. When the drive rod 104 rotates clockwise, it can drive the transmission block 203 to rotate through the synchronous groove 2032. Under the action of the torsion top spring 2042, when the transmission block 203 rotates, the inclined sides of the two sets of transmission gear rings 2031 can abut against each other and rub against each other, thereby driving the positioning block 202 to rotate synchronously clockwise. When the positioning block 202 rotates clockwise, it can pass through the thread of the threaded positioning rod 1011. The moving block 201 moves closer to the fixed block 102, thus clamping the lens body. When it is necessary to release the lens body, simply reverse the rotation of the drive motor 103. At this time, the transmission block 203 will also reverse synchronously. Under the interlocking action between the straight edges of the two sets of transmission gear rings 2031, the positioning block 202 can also reverse synchronously, causing the moving block 201 to move away from the fixed block 102, thus releasing the lens body. The positioning component has the function of limiting the maximum clamping force. When the clamping force is less than the maximum clamping force, the torsion spring 2042 can stably maintain the contact friction between the inclined edges of the two sets of transmission gear rings 2031. The transmission action means that the positioning block 202 and the transmission block 203 will rotate synchronously. When the clamping force is greater than the maximum clamping force, the increase in clamping resistance makes the torsion spring 2042 unable to maintain the anti-friction transmission action between the inclined sides of the two sets of transmission gear rings 2031. After that, even if the transmission block 203 continues to rotate in the forward direction, the inclined sides of the gear teeth of the two sets of transmission gear rings 2031 can squeeze each other, causing the transmission block 203 to move away from the positioning block 202 and compress the torsion spring 2042. As a result, the transmission block 203 can no longer transmit the positioning block 202, and the transmission block 203 will rotate on its own to avoid excessive movement of the moving block 201 and damage to the mirror body.
