Description

Technical Field

[0001] This utility model belongs to the technical field of vertical drilling positioning devices, specifically relating to a drilling depth positioning device for vertical drilling equipment. Background Technology

[0002] With the continuous innovation and development of modern military manufacturing, the precision requirements for parts processing are becoming increasingly stringent. Auxiliary devices for drilling depth positioning have a significant impact on processing accuracy and efficiency. Vertical drilling equipment processing primarily relies on manual operation based on the operator's experience. Specifically, during vertical drilling, after tool setting, the operator must rely on experience and visual perception to control the drill bit feed amount using the vertical scale and pointer graduations on the drill spindle to ensure the processing depth. The depth positioning is achieved by manually controlling the distance the drill bit descends. Traditional processing methods have significant limitations, resulting in low efficiency and difficulty in guaranteeing accuracy. Utility Model Content

[0003] The purpose of this utility model is to provide a drilling depth positioning device for vertical drilling equipment, which reproduces the feed rate 1:1 on the dial of a dial indicator, thereby achieving control over the machining feed rate and has good practicality.

[0004] This utility model is mainly achieved through the following technical solutions: A drilling depth positioning device for a vertical drilling machine includes a frame, a guide column, a mounting column, a first bushing, and a second bushing. The top and bottom ends of the frame are detachably connected to the top and bottom plates of the vertical drilling machine, respectively. A guide column is provided in the middle of the frame, and a mounting column is provided on one side of the frame. A positioning plate is detachably mounted on the mounting column. The first bushing is rotatably mounted on the spindle of the vertical drilling machine, and the second bushing is slidably mounted on the guide column. The first bushing and the second bushing are fixedly connected by a connecting column. A dial indicator is fixedly mounted on one side of the second bushing, located above the positioning plate.

[0005] To better realize this utility model, the second bushing has a snap-fit ​​hole on its side wall, and the first bushing has a plurality of snap-fit ​​grooves on its periphery. The two ends of the connecting post are respectively fixedly connected to the snap-fit ​​hole and the snap-fit ​​groove.

[0006] To better realize this utility model, a support is further provided on one side of the second bushing, and an arc-shaped snap-fit ​​opening groove is provided on the outer side of the support corresponding to the column of the dial indicator.

[0007] To better realize this utility model, a guide column is further provided on the inner side of the frame and fixed by locking screws.

[0008] To better realize this utility model, further, mounting columns are provided on the front and rear sides of the frame, and the mounting columns are connected to the positioning plates through locking bushings. The locking bushings have a U-shaped structure, and a locking hole is provided on one side of the locking bushings, and a connecting support is provided on the other side. The locking bushings are fixedly connected to the positioning plates through the connecting support.

[0009] To better realize this utility model, the frame is further provided with a U-shaped structure and waist-shaped grooves at the upper and lower ends. The waist-shaped grooves at the upper and lower ends of the frame are detachably connected to the top and bottom plates of the vertical drilling equipment by locking screws.

[0010] To better realize this utility model, the vertical drilling equipment is further provided with a frame on both sides.

[0011] The beneficial effects of this utility model are as follows: (1) This utility model realizes that the spindle drives the dial indicator to move longitudinally, and the two produce the same displacement, so that the feed amount is reproduced on the dial of the dial indicator in a 1:1 ratio, thereby realizing the control of the machining feed amount and having good practicality. Secondly, through the setting of several locking grooves on the first bushing, this utility model can flexibly set several positioning devices on the periphery of the vertical drilling equipment to achieve stable and reliable feed amount control.

[0012] (2) This invention can reproduce the drill bit feed rate on a high-precision dial indicator and can achieve drilling depth positioning, which is especially suitable for drilling parts with a drilling depth in the range of 30mm. This invention uses the deviation of the dial indicator to replace the observation of the vertical scale and pointer scale of the drill spindle to measure the feed rate, thus ensuring the requirement of high-precision measurement of the drilling depth of the parts.

[0013] (3) In batch processing, this invention can quickly and accurately determine the depth, significantly reducing the processing time and adjustment time per piece. The machining feed rate of this invention is displayed by a dial indicator. After processing, the depth dimension deviation of the entire batch of parts is within the range of 0.05~0.1mm. However, the deviation in batch processing using the spindle vertical scale and pointer scale is greater than 0.1mm. The processing quality of this invention is stable and reliable. This invention can achieve the processing of parts with other depth ranges by changing dial indicators of different lengths, and has good versatility. Attached Figure Description

[0017] In use, the frame 1 is first placed on the base plate 10 of the vertical drilling equipment 9, and then the top of the frame 1 is locked to the top of the vertical drilling equipment 9. The second bushing 5 is slidable, and the first bushing 4 is connected to the second bushing 5 via the connecting column 6, causing the spindle to drive the first bushing 4 to move longitudinally, thereby moving the first bushing 4. A dial indicator 8 is installed on the first bushing 4. One end of the positioning plate 7 is detachably connected to the mounting column 3, and the other end is located below the dial indicator 8, allowing the dial indicator 8 to lightly touch the positioning plate 7 to calibrate the 0 line. As the vertical drilling equipment 9 operates, the spindle drives the dial indicator 8 to move longitudinally, and both produce the same displacement, replicating the feed rate 1:1 on the dial of the dial indicator 8, achieving precise positioning. This can be used for feed rate control during machining with ordinary vertical drilling equipment 9, and has good practicality.

Figure 5 As shown, the locking bushing 11 has a U-shaped structure, with a locking hole on one side and a connecting support 12 on the other side. The locking bushing 11 is fixedly connected to the positioning piece 7 via the connecting support 12. Specifically, a support is fixedly provided on one side of the second bushing 5, and an arc-shaped snap-fit ​​opening groove is provided on the outer side of the support corresponding to the column of the dial indicator 8.
