Description

Technical Field

[0001] This utility model relates to the field of radial drilling machine technology, and in particular to a drilling positioning device for a radial drilling machine. Background Technology

[0002] A radial drilling machine is a type of drilling machine in which the radial arm can rotate and move up and down around the column, and the spindle box usually moves horizontally on the radial arm. The radial drilling machine can be centered by moving the position of the tool axis, which greatly facilitates the machining of holes on workpieces in single-piece and small-batch production.

[0003] In actual production and processing, the requirements for the drilling position of the workpiece are not the same. Some parts need to be machined with oblique holes so that the connecting bolts can be embedded inside the workpiece when they are installed, so as to hide the connecting bolts. Traditional radial drilling machines are not convenient for machining oblique holes on workpieces (such as thick plates), which limits the flexibility of radial drilling machines in drilling. Utility Model Content

[0036] In this embodiment, as Figure 1 and Figure 2 As shown, a drilling positioning device for a radial drilling machine includes a radial drilling machine body 1, with a base 11 at the bottom end of the body 1. The positioning device includes: two slide rails 2, symmetrically distributed on the upper surface of the base 11, with a slide seat 21 slidably connected to the top of each slide rail 2; a deflection plate 3, located between the two slide rails 2, connected to the slide seat 21 via a pin, and equipped with a locking member 31 to constrain the tilt angle of the deflection plate 3; and a workpiece bearing plate 4, slidably connected to the deflection plate 3, equipped with a clamping member 41 to fix the plate-shaped workpiece and the workpiece bearing plate 4. The workpiece bearing plate 4 tilts with the deflection plate 3 to facilitate the radial drilling machine body 1 in machining inclined holes in the plate-shaped workpiece.

[0037] Thus, the workpiece requiring the oblique hole is fixed on the top of the workpiece support plate 4 using the clamping member 41. Then, the deflection plate 3 is rotated between the two slides 21. The deflection plate 3 drives the workpiece support plate 4 and the workpiece to deflect to a preset angle. The tilt angle of the deflection plate 3 is fixed using the locking member 31. The workpiece is adjusted by moving the slides 21 on the top of the two slide rails 2 and moving the workpiece support plate 4 on the outer wall of the deflection plate 3. The drill bit of the radial drilling machine body 1 drills a hole vertically in the workpiece to form an oblique hole in the workpiece.

[0038] Specifically, the radial drilling machine body 1 is a well-known technology in the art and will not be described in detail. The slide rail 2 is designed with two rails. The slide block 21 can move along the slide rail 2. The slide block 21 is machined with a slot that matches the bolt 312. The deflection plate 3 is located between the two slide blocks 21. The workpiece bearing plate 4 is used to install the workpiece.

The locking block 311 and the slide 21 are connected by the bolts 312 to fix the tilt angle of the deflection plate 3.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, threaded holes 42 are evenly distributed on the top surface of the workpiece support plate 4. Threaded pins 42a are internally threaded into the threaded holes 42. Rubber blocks 42b are fixedly connected to the outer periphery of the threaded pins 42a. The rubber blocks 42b are used to support the bottom end of the plate-shaped workpiece.

[0044] Specifically, the threaded hole 42 is designed with multiple threads, and the threaded pin 42a is used to install the rubber block 42b, which is used to support the workpiece.

[0045] In some embodiments, such as Figure 3 As shown, a circular tube clamp 43 is disposed on the lower surface of the workpiece support plate 4, and the two ends of the circular tube clamp 43 are connected to the workpiece support plate 4 by positioning pins 43a.

[0046] Specifically, the round tube clamp 43 is machined with an arc, and there are four round tube clamps 43, which are evenly distributed along the workpiece bearing plate 4. The outer wall of the positioning pin 43a is machined with threads, and each round tube clamp 43 is equipped with a positioning pin 43a at both ends.

[0047] In some embodiments, such as Figure 3 As shown, a V-groove 44 is provided on the lower surface of the workpiece bearing plate 4. The V-groove 44 assists the round tube clamping plate 43 in clamping the round tube-shaped workpiece.

[0048] Specifically, the V-groove 44 is located at the bottom of the workpiece bearing plate 4, and the V-groove 44 assists the round tube clamping plate 43 in clamping the round tube-shaped workpiece.

[0049] In some embodiments, such as Figure 2 As shown, the workpiece support plate 4 is equipped with a plug rod 45, and the workpiece support plate 4 is connected to the deflection plate 3 through the plug rod 45.

[0050] Specifically, the plug rod 45 is used to fix the position of the workpiece bearing plate 4 on the outer wall of the deflection plate 3.

[0052] Specifically, the outer wall of the top pin 211 is threaded, and the top pin 211 is used to fix the position of the slide block 21 on the slide rail 2.

[0053] In some embodiments, such as Figure 5 As shown, both the slide rail 2 and the deflection plate 3 are machined with graduations, which are used to determine the machining position of the workpiece.

[0054] Specifically, by machining scales on slide rail 2 and deflection plate 3, it is easy to determine the machining position of the workpiece.

[0055] In some embodiments, such as Figure 5 As shown, a collection shell 11a is disposed in the base 11, which is used to collect the debris generated by drilling.

[0056] The collection shell 11a is used to collect the debris generated during processing.

[0057] The working principle of this application is illustrated below with a preferred embodiment:

[0058] When it is necessary to machine oblique holes on a sheet metal workpiece, the threaded pin 42a is connected to the threaded hole 42 on the workpiece support plate 4. Then, the rubber block 42b is placed on the workpiece support plate 4 along with the threaded pin 42a. (When installing multiple rubber blocks 42b to support the sheet metal workpiece, the installation position of the rubber blocks 42b needs to be adjusted to avoid the drilling path of the drill bit of the radial drilling machine body 1). Next, the workpiece is placed on the top of the rubber block 42b. Then, the threaded rod 412 is rotated in the threaded cylinder 411. The threaded rod 412 drives the pressure plate 413 to move towards the side closer to the workpiece. The multiple pressure plates 413, in conjunction with the workpiece support plate 4, clamp the workpiece. Then, the workpiece is rotated between the two slides 21. The deflection plate 3 is moved. After the deflection plate 3 tilts the workpiece to the machining angle, the clamping block 311 is fixed to the slide block 21 with bolts 312 to fix the deflection angle of the deflection plate 3. The slide block 21 is moved on the top of the slide rail 2. The two slide blocks 21 drive the deflection plate 3 and the workpiece to move. The position of the slide block 21 on the slide rail 2 is fixed with the top pin 211. Then the workpiece bearing plate 4 is moved on the outer wall of the deflection plate 3. The workpiece bearing plate 4 drives the workpiece to move. The position of the workpiece bearing plate 4 on the deflection plate 3 is fixed with the plug rod 45 to adjust the X-axis and Y-axis of the workpiece, thereby determining the drilling position of the workpiece. At this time, the drill bit of the radial drilling machine body 1 moves vertically downward to process the inclined hole of the workpiece.

[0059] Flip the deflection plate 3 between the slides 21 by 180 degrees, and use bolts 312 to re-fix the clamping block 311 and the slide 21. At this time, the side of the workpiece bearing plate 4 with the V-groove 44 faces upward. Place the pipe in the V-groove 44, and then put the round pipe clamp 43 on the outer circumference of the pipe. Use the positioning pin 43a to connect the round pipe clamp 43 and the workpiece bearing plate 4 to fix the processing position of the pipe. Use the drill bit of the radial drilling machine body 1 to drill holes in the pipe.
