Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, specifically a drilling machine with an anti-deviation structure. Background Technology

[0002] Agricultural product processing equipment refers to mechanical devices used to process, refine, and enhance the added value of agricultural products. These devices are widely used in grains, fruits and vegetables, meat, and aquatic products. They can perform functions such as cleaning, sorting, peeling, cutting, drying, crushing, juicing, and packaging. During the manufacturing process, a drilling machine is used to drill holes in the parts of the agricultural product processing equipment; these holes are typically used for installing connectors.

[0003] However, when existing drilling machines for machining equipment drill parts, due to the relatively long drill rods of some drilling machines, the drill rods are prone to lateral swaying during the descent and rotation process, causing deviation during drilling and reducing the working quality of the drilling machine. Therefore, it is necessary to improve the existing drilling machines for machining equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a drilling machine with an anti-deviation structure to solve the problem mentioned in the background art that the drill rod of the drilling machine used for machining of mechanical equipment on the market is prone to lateral swaying during the downward rotation process, which causes deviation during drilling and reduces the working quality of the drilling machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling machine with an anti-deviation structure, comprising a base and a support. A body is mounted on one end of the base, and an electric push rod is connected to the top of the body. A transmission mechanism is installed in the built-in groove of the base. The support is connected to both ends of the transmission mechanism. A limit frame is connected to one end of the support. An anti-deviation mechanism is provided on the inner side of the limit frame. The anti-deviation mechanism includes a first limit ring, a docking block, a positioning groove, a second limit ring, and a ball bearing. The inner side of the limit frame is provided with a first limit ring and a second limit ring. Positioning blocks are fixed at both ends of the first limit ring, and positioning grooves are opened at both ends of the second limit ring.

[0006] Preferably, both the first and second limiting rings are fixedly connected to a docking block on the side near the limiting frame, and the inner surfaces of the first and second limiting rings are movably fitted with annularly distributed balls, and the inner surface of the limiting frame is provided with a docking groove.

[0007] Preferably, a worktable assembly is mounted on the surface of the base near the bracket, a guide rod is fixed on the upper surface of the machine body near the electric push rod, a support plate is connected to the top of the electric push rod, and the support plate and the guide rod are slidably sleeved together.

[0008] Preferably, a second motor is installed at the end of the support plate away from the guide rod, and a drill rod is connected below the second motor via a coupling. The drill rod is located inside the first and second limiting rings.

[0009] Preferably, the transmission mechanism includes a connecting rod, a transmission plate, a first motor, a slide rod, and a slider. The first motor is installed in the built-in slot of the base by bolts, and the top of the first motor is connected to the transmission plate by a coupling.

[0010] Preferably, a slide rod is fixed in the built-in groove near the bottom of the transmission plate of the base, and a slider is slidably sleeved on the outer side of the slide rod. The middle part of the slider is connected to both ends of the transmission plate by a connecting rod through a movable shaft.

[0011] Preferably, the upper part of the slider is connected to the bracket, and a sliding groove is formed on the surface of the base near the bracket, and the sliding groove and the bracket are slidably connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. An anti-deviation mechanism is provided. By fitting the first and second limit rings onto the outside of the drill rod, the first limit ring drives the positioning block to insert into the positioning groove of the second limit ring. During the downward rotation of the drill rod, the ball bearings reduce the friction between the first and second limit rings and the drill rod. This does not affect the rotation and descent of the drill rod, but it can limit the lateral sway of the drill rod and prevent deviation, thus improving the working quality of the drilling machine.

[0014] 2. Equipped with a transmission mechanism and support, when it is necessary to disassemble the No. 1 and No. 2 limit rings, the No. 1 motor is started, causing the transmission plate to rotate clockwise. The two ends of the transmission plate push the connecting rod, and one end of the connecting rod pushes the slider away from each other on the outside of the sliding rod. At the same time, the two ends of the connecting rod rotate on the surface of the transmission plate and the slider. The slider then drives the support to slide in the slide groove. The support drives the limit frame to move away from each other, and then pulls the No. 1 and No. 2 limit rings outward, causing the No. 1 and No. 2 limit rings to drive the docking block to disengage from the docking groove. The No. 1 and No. 2 limit rings can be quickly disassembled and replaced, improving the convenience of the drilling machine. Attached Figure Description

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 This utility model provides a technical solution: a drilling machine with an anti-offset structure, including a base 1 and a support 8. A body 2 is installed at one end of the base 1, and an electric push rod 3 is connected to the top of the body 2. A transmission mechanism 6 is installed in the built-in groove of the base 1. The support 8 is connected to both ends of the transmission mechanism 6. A worktable assembly 12 is installed on the surface of the base 1 near the support 8. A guide rod 5 is fixed on the upper surface of the body 2 near the electric push rod 3. A support plate 4 is connected to the top of the electric push rod 3. The support plate 4 and the guide rod 5 are slidably sleeved. A second motor 7 is installed at the end of the support plate 4 away from the guide rod 5. A drill rod 11 is connected to the bottom of the second motor 7 through a coupling.

[0024] Please see Figures 1-6One end of the bracket 8 is connected to a limiting frame 10. The inner side of the limiting frame 10 is provided with an anti-deviation mechanism 9. The anti-deviation mechanism 9 includes a first limiting ring 901, a docking block 902, a positioning groove 903, a second limiting ring 904, and a ball bearing 905. The inner side of the limiting frame 10 is provided with a first limiting ring 901 and a second limiting ring 904. Positioning blocks 14 are fixed to both ends of the first limiting ring 901, and both ends of the second limiting ring 904 are open. A positioning groove 903 is provided. The first limiting ring 901 and the second limiting ring 904 are both fixedly connected to the docking block 902 on the side near the limiting frame 10. The inner surfaces of the first limiting ring 901 and the second limiting ring 904 are movably installed with annularly distributed balls 905. The drill rod 11 is located inside the first limiting ring 901 and the second limiting ring 904. The first limiting ring 901 and the second limiting ring 904 are both sleeved with the limiting frame 10.

[0025] In practical implementation, when existing drilling machines used for machining equipment drill parts, the drill rod 11 of some drilling machines is relatively long. During the downward rotation of the drill rod 11, it is prone to lateral swaying, which causes deviation during drilling and reduces the working quality of the drilling machine. This can be addressed by fitting a first limiting ring 901 and a second limiting ring 904 onto the outside of the drill rod 11. The first limiting ring 901 drives the positioning block 14 to insert into the positioning groove 903 of the second limiting ring 904. During the downward rotation of the drill rod 11, the ball bearing 905 reduces the friction between the first limiting ring 901, the second limiting ring 904 and the drill rod 11. This does not affect the rotation and descent of the drill rod 11, but it can limit the lateral swaying of the drill rod 11 and prevent deviation, thereby improving the working quality of the machining drilling machine.

[0026] Please see Figures 1-3 and Figure 6 The inner surface of the limiting frame 10 is provided with a docking groove 15. The transmission mechanism 6 includes a connecting rod 601, a transmission plate 602, a first motor 603, a sliding rod 604, and a slider 605. The first motor 603 is installed in the built-in groove of the base 1 by bolts. The top of the first motor 603 is connected to the transmission plate 602 by a coupling. The sliding rod 604 is fixed in the built-in groove of the base 1 near the transmission plate 602. The slider 605 is slidably sleeved on the outer side of the sliding rod 604. The middle part of the slider 605 is connected to both ends of the transmission plate 602 by a connecting rod 601 through a movable shaft. The top of the slider 605 is connected to the bracket 8. The surface of the base 1 near the bracket 8 is provided with a sliding groove 13, and the sliding groove 13 is slidably connected to the bracket 8. The cross-sectional shape of the docking block 902 and the docking groove 15 is polygonal. The shape of the limiting frame 10 is semi-circular.

[0027] In practice, after the first limiting ring 901 and the second limiting ring 904 have been limiting the drill rod 11 for a long time, they will wear out and need to be replaced. The first motor 603 can be started directly, which will drive the transmission plate 602 to rotate clockwise. The two ends of the transmission plate 602 push the connecting rod 601, and one end of the connecting rod 601 pushes the slider 605 to slide away from each other on the outside of the slider 604. At the same time, the two ends of the connecting rod 601 rotate on the surface of the transmission plate 602 and the slider 605. The slider 605 then drives the bracket 8 to slide in the groove 13. The bracket 8 drives the limiting frame 10 to move away from each other, and then pulls the first limiting ring 901 and the second limiting ring 904 outward, so that the first limiting ring 901 and the second limiting ring 904 drive the docking block 902 to disengage from the docking groove 15. The first limiting ring 901 and the second limiting ring 904 can be quickly disassembled and replaced, which improves the convenience of the drilling machine.

[0028] Working principle: When using this drilling machine with anti-offset structure, the anti-offset mechanism 9 is first installed on the outside of the drill rod 11 through the bracket 8 and the limit frame 10. Then, the drill rod 11 is positioned by the first limit ring 901 and the second limit ring 904 to prevent the drill rod 11 from swaying laterally and offsetting. The electric push rod 3 retracts and drives the support plate 4 to descend. At the same time, the support plate 4 slides downward outside the guide rod 5. Simultaneously, the second motor 7 drives the drill rod 11 to rotate and drill the equipment parts on the worktable assembly 12. When it is necessary to disassemble the first limit ring 901 and the second limit ring 904, they can be quickly disassembled and replaced through the transmission mechanism 6, which improves the convenience and working efficiency of the drilling machine. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
