Description

Technical Field

[0001] The utility model relates to the field of mold processing, in particular to a radial drilling machine for mold processing. Background Art

[0002] Mold processing refers to the processing of forming and blanking tools. When processing molds, radial drilling machines are often used to drill holes. A radial drilling machine is a drilling machine with a rocker arm that can rotate and rise and fall around a column, and usually the spindle box moves horizontally on the rocker arm.

[0003] At present, there is no cleaning mechanism on the column of the existing radial drilling machine. Therefore, during the operation, the engine oil on the column will adsorb dust, iron filings and other impurities on the surface of the column. When the spindle moves, it is easy to bring the impurities into the spindle to form a blockage, causing abnormal noise or even damage, thereby reducing the practicality and service life of the radial drilling machine. At the same time, the existing radial drilling machine does not have a supporting structure installed. Since the arm is installed on the spindle and the contact surface is limited, the vibration generated by the operation of the drilling mechanism or the inertia generated by the movement of the arm can easily cause the arm to vibrate up and down, thereby reducing stability and also reducing the accuracy of mold processing. Summary of the invention

[0004] The main purpose of the utility model is to solve the problem that the above-mentioned existing radial drilling machine for mold processing does not have a cleaning mechanism and a support frame, so it is easy for impurities to enter the main shaft during use to cause abnormal noise and damage, and it is easy to cause the arm to shake during work, thereby reducing the service life and practicality while also reducing the quality and stability of mold processing. A radial drilling machine for mold processing is provided.

[0005] The specific scheme of the utility model is: a radial drilling machine for mold processing, comprising a column and a lifting mechanism, the column is slidably mounted with a main shaft, one end of the main shaft is provided with a large arm, the large arm is provided with a drilling mechanism, both ends of the main shaft are respectively provided with cleaning mechanisms, the cleaning mechanisms include a fixing ring, the fixing ring is provided at both ends of the main shaft, one end of the fixing ring is provided with a fixing groove, a scraping ring is movably connected inside the fixing groove, the end of the scraping ring away from the fixing groove is close to the column, the scraping ring matches the fixing groove, the scraping ring is provided with a notch, the fixing ring is evenly arranged with screw holes, and the screw holes are threadedly connected with bolts.

[0006] According to the above technical solution, the cleaning mechanisms at both ends are driven to move when the main shaft moves, and the scraper ring is in contact with the main shaft surface to scrape and clean the dirty oil and iron filings on the main shaft surface during movement, thereby preventing the main shaft from bringing impurities into the main shaft during movement.

[0007] Furthermore, a support frame is fixed to one end of the fixing ring at the bottom of the main shaft, and the end of the support frame away from the fixing ring is fixedly connected to the boom. The support frame is located below the boom, and a movable hole is provided on the support frame, and the movable hole is coaxial with the lifting mechanism.

[0008] According to the above technical solution, the support frame can effectively assist in supporting the upper arm from the bottom, thereby increasing the contact surface between the upper arm and the main shaft to avoid shaking of the upper arm during movement.

[0009] Furthermore, the angle between the support frame and the main axis is 35°~65°.

[0010] According to the above technical solution, a 35°~65° angle is set between the support frame and the main shaft, so that the support frame supports from the bottom to form a triangular area, which further improves the stability.

[0011] Furthermore, the scraping ring is in a conical shape, and the end of the scraping ring with a larger diameter is movably connected to the fixing ring.

[0012] According to the above technical solution, the convenience of use is improved by the cone shape, and the end with a smaller diameter fits the main shaft for scraping and cleaning.

[0013] Furthermore, the scraper ring is made of rubber.

[0014] According to the above technical solution, the rubber material will not cause damage to the surface of the spindle, and at the same time can achieve a cleaning effect.

[0015] Compared with the prior art, the utility model has the following advantages: the radial drilling machine for mold processing is equipped with a cleaning mechanism, which can clean dust and impurities on the surface of the column during the movement of the main shaft, thereby preventing impurities from entering the main shaft and causing abnormal noise and damage; at the same time, after the cleaning mechanism is used for a long time, its scraper ring can be replaced to further improve the practicality, thereby increasing the service life of the radial drilling machine for mold processing; the radial drilling machine for mold processing is equipped with a support frame, which can effectively support the upper arm from the bottom to form a triangular area, and at the same time also increases the contact surface between the upper arm and the main shaft, reduces the shaking generated when the upper arm moves and the vibration generated during drilling, thereby improving the stability and processing quality of the radial drilling machine for mold processing.

[0022] Embodiment 1

[0023] See also Figure 1-5 The present embodiment is a radial drilling machine for mold processing, which is composed of a column 1 and a lifting mechanism 2. The lifting mechanism 2 is used to adjust the spindle 3 to move up and down on the column 1. The column 1 is used to support the entire spindle 3 and the large arm 4. At the same time, the spindle 3 moves up and down on the column 1 to achieve the effect of adjusting the large arm 4. The large arm 4 is fixed to one end of the spindle 3. The large arm 4 is provided with a drilling mechanism 5. The drilling mechanism 5 can move horizontally on the large arm 4 to achieve the function of the drilling mechanism 5. The drilling mechanism 5 is used to drill holes in the material. A group of cleaning mechanisms are respectively provided at the top and bottom of the spindle 3. The cleaning mechanism is composed of a fixing ring 6, a fixing groove 7, a scraping ring 8, a notch 9, a screw hole 10 and a bolt 11. The two ends of the spindle 3 are welded respectively. A fixing ring 6 is fixed, and the middle part of the fixing ring 6 is hollowed out and can move with the main shaft 3. The fixing ring 6 is used to install a scraper ring 8. A fixing groove 7 is provided on the top of the fixing ring 6, and the fixing groove 7 is movably connected to the scraper ring 8. At the same time, the scraper ring 8 is in close contact with the column 1 at one end away from the fixing groove 7, which is convenient for cleaning the column 1, and the fixing groove 7 is a circular ring that matches the shape of the scraper ring 8, and the scraper ring 8 is not sealed and has a notch 9. The notch 9 is convenient for the installation of the scraper ring 8. The scraper ring 8 can be unfolded to wrap the main shaft 3, and then inserted into the fixing groove 7 for installation. A plurality of screw holes 10 are evenly arranged on the surface of the fixing ring 6, and bolts 11 are threadedly connected to the screw holes 10. The bolts 11 are used to fix the scraper ring 8.

[0024] Furthermore, the scraper ring 8 is conical in shape, and the large end of the scraper ring 8 is installed on the fixing ring 6, and the small end with a smaller diameter is in contact with the column 1, and further, when the conical surface of the scraper ring 8 is an inclined surface, it matches the fixing groove 7 at the same time, so the inner hole of the fixing groove 7 is also an inclined surface.

[0025] Furthermore, the scraper ring 8 is made of rubber material and has elasticity.

[0026] The working principle of this embodiment is as follows: when installing the scraper ring 8, first manually unfold the scraper ring 8 through the notch 9, point the big end of the scraper ring 8 toward the fixed groove 7, and then wrap it on the column 1, and finally insert the big end of the scraper ring 8 into the fixed groove 7 to connect with the fixing ring 6, so that the small end of the scraper ring 8 is in contact with the column 1, and finally connect it with the screw hole 10 through the bolt 11 to achieve the fixing effect. When the main shaft 3 moves up and down on the column 1, the scraper ring 8 at both ends can effectively contact the column 1, thereby scraping off the dust and iron filings adsorbed by the dirty oil on the surface of the column 1, and avoiding dust and iron filings from being brought into the main shaft 3 to form a blockage, causing abnormal noise or even damage to the main shaft 3 when it moves, thereby improving the service life and the smoothness of the movement of the main shaft 3, and when the scraper ring 8 is worn after long-term use, it can be replaced by removing the bolt 11, further improving the practicality and service life of the radial drilling machine for mold processing.

[0027] Embodiment 2

[0028] The structure of this embodiment is basically the same as that of embodiment one, and the following features are added on the basis of embodiment one: a support frame 12 is welded to one end of the fixed ring 6 at the bottom of the main shaft 3, and the support frame 12 is welded to the boom 4 on the end away from the main shaft 3. The support frame 12 is located directly below the boom 4 to play a supporting effect, thereby increasing the contact surface between the boom 4 and the main shaft 3. A movable hole 13 is provided on the support frame 12 and the movable hole 13 is located directly below the lifting mechanism 2 and is coaxial with the lifting mechanism 2, so as to avoid affecting the normal operation of the screw rod when the lifting mechanism 2 is working.

[0029] Furthermore, an angle of 35° to 65° is set between the support frame 12 and the main shaft 3, so that the support frame 12 is supported from the bottom to form a triangular area, which further improves stability.

[0030] The working principle of this embodiment is as follows: when the drilling mechanism 5 generates vibration during drilling or the upper arm 4 generates inertia during movement, since a support frame 12 is provided at the bottom of the upper arm 4, and the angle between the support frame 12 and the main shaft 3 is 35°~65°, a triangular area is formed between the support frame 12 and the upper arm 4, the contact surface between the upper arm 4 and the main shaft 3 can be effectively improved and a supporting effect can be achieved, thereby reducing the shaking of the upper arm 4 during operation, thereby improving the accuracy of drilling and the stability of the movement of the upper arm 4, and improving the production quality of the mold.
