Description

Technical Field

[0001] This utility model relates to the technical field of feeding mechanisms, specifically an automatic feeding mechanism for a grease nipple drilling machine. Background Technology

[0002] Grease fittings are commonly used lubrication components in mechanical equipment. In the current technology, the drilling of grease fittings is usually done manually, that is, the operator places the grease fittings one by one at the processing station, the drilling equipment completes the drilling, and then the fittings are manually removed. This processing method has the following drawbacks:

[0003] 1. Manual feeding and drilling cannot be carried out in parallel, resulting in the equipment being idle while waiting for feeding, with a long processing cycle, making it difficult to meet the needs of mass production;

[0004] 2. When manually placing the grease fitting, positional deviations are prone to occur, causing the drilling position to shift and affecting the product qualification rate;

[0005] 3. Some drilling machines require additional clamps to hold the grease fittings in place, which increases the operational complexity and reduces production efficiency.

[0006] 4. Loading and unloading operations are all carried out in the drilling area, which can easily lead to production accidents due to operational errors. Utility Model Content

[0007] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide an automatic feeding mechanism that can accelerate production efficiency, ensure drilling accuracy, and improve production safety.

[0008] The technical solution adopted by this utility model to achieve the above objectives is: an automatic feeding mechanism for a grease nipple drilling machine, including a frame, a linear motion module, and a material tray. The material tray is provided with multiple sets. The linear motion module is provided on the frame. The linear motion module includes a linear motion table. Multiple sets of positioning columns are fixedly connected to the linear motion table.

[0009] The top surface of the material tray is provided with multiple sets of material holes, and the bottom surface of the material tray is provided with positioning holes that cooperate with the positioning pins. The positioning pins are inserted into the positioning holes, and the outer wall of the positioning pins abuts against the inner wall of the positioning holes.

[0010] In the above technical solution, the linear motion module further includes a guide column, a lead screw, and a drive motor. The guide column is fixedly connected to the frame, and the linear motion stage is slidably connected to the guide column. A lead screw seat is fixedly connected to the linear motion stage, and the lead screw is threadedly connected to the lead screw seat. The drive motor is fixedly connected to the frame, and the drive motor is poweredly connected to the lead screw.

[0011] In the above technical solution, the linear motion stage is provided with an upper push port corresponding to the material tray, and the frame is provided with a material pushing component corresponding to the upper push port.

[0012] In the above technical solution, the pushing component includes an electric telescopic cylinder, a sliding column, and a pushing plate. The sliding column is slidably connected to the frame, and the pushing plate is fixedly connected to the top of the sliding column. The electric telescopic cylinder is fixedly connected to the frame, and the piston end of the electric telescopic cylinder is fixedly connected to the pushing plate.

[0013] In the above technical solution, the feed hole includes a cylindrical hole and a prismatic hole located on the upper part of the cylindrical hole, and the screwing table of the grease nipple is fitted into the prismatic hole.

[0014] In the above technical solution, handles are fixedly connected to both sides of the corresponding material tray.

[0015] In the above technical solution, the material holes are arranged in a rectangular array on the material tray.

[0016] The beneficial effects of this utility model are as follows: Grease fittings to be drilled can be placed one by one into the holes of a material tray. The tray is then placed on a linear motion table and positioned using positioning pins and holes. A drive motor rotates the lead screw, causing the linear motion table to move the tray to the drilling position. A three-axis drilling machine can then drill the grease fittings on the tray sequentially. During drilling, the operator can place grease fittings on another set of trays. After drilling is complete, the linear motion module moves the tray out of the drilling position. The operator can then remove the drilled tray and place a new tray on the linear motion table. This structure eliminates human-machine waiting time by allowing for parallel tray pre-loading and processing, thus accelerating production efficiency. Furthermore, the material holes position the grease fittings, eliminating the need for additional fixtures. The positioning pins and holes position the tray, reducing subsequent drilling operations and ensuring precise drilling accuracy. Additionally, separating the loading / unloading area from the drilling area prevents operators from entering hazardous areas of machining, improving production safety. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figures 1-5 An automatic feeding mechanism for a grease nipple drilling machine includes a frame 100, a linear motion module, and a material tray 200. The material tray 200 is provided with multiple sets. First, the frame 100 is provided with a linear motion module. In this embodiment, the linear motion module includes a linear motion table 301, a guide column 302, a lead screw 303, and a drive motor 304. That is, the guide column 302 is fixedly connected to the frame 100, and the linear motion table 301 is slidably connected to the guide column 302. The lead screw seat is fixedly connected to the linear motion table 301, and the lead screw 303 is threadedly connected to the lead screw seat. The drive motor 304 is fixedly connected to the frame 100 and is poweredly connected to the lead screw 303. When the drive motor 304 drives the lead screw 303 to rotate, the linear motion table 301 can perform linear motion on the guide column 302. Of course, any structure that can make the linear motion table 301 perform linear motion can be used, except for the above structure.

[0025] Furthermore, the aforementioned linear motion table 301 is also fixedly connected to multiple sets of positioning columns 305, specifically four sets of positioning columns 305, which are located at the four corners of the linear motion table 301.

[0026] Furthermore, each of the aforementioned material trays 200 has multiple sets of material holes 201 arranged in a rectangular array on its top surface. This rectangular array arrangement facilitates subsequent drilling operations by the three-axis drilling machine. In this embodiment, the material hole 201 includes a cylindrical hole 2011 and a prismatic hole 2012 located above the cylindrical hole 2011. The material hole 201 is used to place the grease nipple 500, and the screwing table of the grease nipple 500 can be fitted into the prismatic hole 2012. In this way, the grease nipple 500 can be positioned and the grease can be greased. When the nozzle 500 is used for drilling, it can prevent the grease nozzle 500 from rotating. In addition, a positioning hole 202 is provided on the bottom surface of the material tray 200 in conjunction with the positioning pin 305. The positioning pin 305 is inserted into the positioning hole 202, and the outer wall of the positioning pin 305 abuts against the inner wall of the positioning hole 202. In this way, the material tray 200 can be positioned. The operation is simple, and because the outer wall of the positioning pin 305 abuts against the inner wall of the positioning hole 202, the material tray 200 can be prevented from shaking, ensuring the accuracy of subsequent drilling.

[0027] Furthermore, handles 203 are fixedly connected to both sides of the material tray 200 to facilitate the removal of the material tray 200;

[0028] Furthermore, the linear motion table 301 is provided with an upper push port 3011 corresponding to the material tray 200, and the frame 100 is provided with a pushing component corresponding to the upper push port 3011. The pushing component is used to push the material tray 200 down from the positioning post 305 so that the operator can remove the material tray 200. In this embodiment, the pushing component includes an electric telescopic cylinder 401, a sliding post 402 and a pushing plate 403. The sliding post 402 is slidably connected to the frame 100, and the top end of the sliding post 402 is fixedly connected to the pushing plate 403. The electric telescopic cylinder 401 is fixedly connected to the frame 100, and the piston end of the electric telescopic cylinder 401 is fixedly connected to the pushing plate 403. In this way, the electric telescopic cylinder 401 can drive the pushing plate 403 to rise, and the pushing plate 403 can push the material tray 200 out of the positioning post 305.

[0029] In summary, this embodiment discloses an automatic feeding mechanism for a grease nipple 500 drilling machine, which is mainly used for feeding grease nipple 500 during drilling. Specifically, the operator can place the grease nipple 500 to be drilled one by one into the material hole 201 of the material tray 200, and then place the material tray 200 on the linear motion table 301. The material tray 200 is positioned by the positioning pin 305 and the positioning hole 202. Then, the drive motor 304 drives the lead screw 303 to rotate, so that the linear motion table 301 drives the material tray 200 to the drilling position. The three-axis drilling machine can then drill the grease nipple 500 on the material tray 200 in sequence.

[0030] During the drilling process, the workers can place the grease nipple 500 on another set of material trays 200;

[0031] After drilling is completed, the linear motion module can drive the material tray 200 to move out of the drilling position. Then, the electric telescopic cylinder 401 drives the pusher plate 403 to push the material tray 200 off the positioning post 305, and the workers can easily remove the material tray 200 after drilling.

[0032] Finally, the staff placed the new material tray 200 on the linear motion table 301.
