Description

Technical Field

[0001] This utility model relates to the field of radial drilling machines, and more specifically, to a foot-operated workpiece table lifting mechanism for radial drilling machines. Background Technology

[0002] In the machining process, radial drilling machines are a commonly used piece of equipment, and the lifting operation of their workpiece table plays a crucial role in the smooth loading or positioning of the workpiece to be processed.

[0003] Existing radial drilling machines typically have a lifting and adjusting mechanism for the workpiece table, but most of these are manually operated. While convenient, this lacks the ability to be operated by foot, hindering the operator's ability to free their hands. Furthermore, the handwheels of the lifting and adjusting mechanism are usually located at the bottom or side of the workpiece table, close to the bottom of the drilling arm and drill bit, increasing the risk of the operator's head hitting these parts during adjustment. Therefore, we propose a foot-operated workpiece table lifting mechanism for radial drilling machines to address these problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a foot-operated workpiece table lifting mechanism for a radial drilling machine. This mechanism, through the installation of a rotating wheel, allows the operator to adjust the workpiece table lifting process simply by stepping on the foot pedal of the rotating wheel, eliminating the need for hand operation and freeing up the operator's hands. Furthermore, the rotating wheel, driven by a steering gear one, a steering gear two, and a telescopic transmission shaft, is mounted on one side of the radial drilling machine base, far from the bottom of the radial drilling machine's arm, the drill bit mounting position, and the workpiece table. This significantly reduces the risk of the operator's head hitting the radial drilling machine's arm or drill bit mounting position during adjustment, improving safety during use.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A foot-operated workpiece table lifting mechanism for a radial drilling machine includes a radial drilling base. A mounting groove is provided on one side of the radial drilling base, and a shear-type lifting platform is installed inside the mounting groove. The shear-type lifting platform includes a platform section, two movable fork arm ends, and a base frame section. A workpiece table is fixedly mounted on the top of the platform section by bolts. The two movable fork arm ends are rotatably connected by a rotating shaft, and each of the two movable fork arm ends has a gear mounting opening inside. A gear is fixedly mounted on the outside of the rotating shaft located inside the gear mounting opening, and a rack meshes with the bottom of each of the two gears. The bottoms of the two racks are fixedly mounted at corresponding positions on the base frame section.

[0009] A slide base is fixedly installed on one side of the outer wall of the radial drill base. The slide base has a stroke groove inside, which extends through the mounting groove. A slide plate is slidably connected to the slide base. One end of the rotating shaft passes through the stroke groove to the outside of the slide plate. A worm gear is fixedly installed at one end of the rotating shaft. A worm is engaged at the top of the worm gear. Both ends of the worm are rotatably connected to bearing seats. The two bearing seats are fixedly installed on the slide plate.

[0010] Furthermore, a telescopic drive shaft is provided on one side of the slide base. One end of the telescopic drive shaft is connected to one end of the worm gear via a coupling. A steering gear is fixedly installed on one side of the radial drilling base. The output shaft on one side of the steering gear is connected to the other end of the telescopic drive shaft via a coupling.

[0011] Furthermore, a column is fixedly welded to one side of the top of the radial drilling base, and a second steering gear is fixedly installed on the top of the column. A connecting shaft is provided between the first steering gear and the second steering gear. The two ends of the connecting shaft are respectively connected to the input shaft at the top of the first steering gear and the output shaft at the bottom of the second steering gear through couplings. A wheel is fixedly installed on the input shaft on one side of the second steering gear, and several pedals are fixedly welded to the wheel at equal intervals.

[0012] Furthermore, the width of the workpiece stage is equal to the width of the inner wall of the mounting groove, and the length of the workpiece stage is less than the length of the mounting groove.

[0013] Furthermore, the width of the stroke groove is greater than the diameter of the outer wall of the shaft, and the length of the stroke groove is greater than the length of the two racks.

[0014] Furthermore, a cylindrical ruler is fixedly installed on the base of the radial drill by bolts, and an indicator rod is fixedly installed on one side of the workpiece table corresponding to the position of the ruler, with the end of the indicator rod in contact with the outer surface of the ruler.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this solution, the rotating wheel is set so that when adjusting the workpiece table, the adjustment process can be achieved by the operator stepping on the foot pedal on the rotating wheel. The operator does not need to operate with his hands, which frees up the operator's hands. At the same time, the rotating wheel is installed on one side of the radial drilling base through the drive connection of steering gear one, steering gear two and telescopic transmission shaft, which is far away from the bottom of the radial drilling machine's arm, the drill bit installation position and the workpiece table. This greatly reduces the risk of the operator's head hitting the radial drilling machine's arm or the drill bit installation position when adjusting, and improves the safety during use.

[0018] (2) In this scheme, foot operation can better coordinate with the body's natural movements. For example, when standing, the operation is carried out by the strength of the legs, which is more in line with the ergonomic principle. In contrast, manual operation may require workers to bend over or reach out frequently, which can easily cause fatigue. Foot operation can allow workers to maintain a more comfortable working posture, reduce fatigue, and thus maintain high efficiency during long working hours. Attached Figure Description

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example 1:

[0028] Please see Figures 1-5 A foot-operated workpiece table lifting mechanism for a radial drilling machine includes a radial drilling base 1. A mounting groove 101 is provided on one side of the radial drilling base 1. A shear-type lifting platform 2 is provided inside the mounting groove 101. The shear-type lifting platform 2 includes a platform part 201, two movable fork arm ends 202, and a base frame part 203. A workpiece table 3 is fixedly installed on the top of the platform part 201 by bolts. The two movable fork arm ends 202 are rotatably connected by a rotating shaft 4. A gear mounting opening 2021 is provided inside the two movable fork arm ends 202. A gear 5 is fixedly installed on the outside of the rotating shaft 4 inside the gear mounting opening 2021. A rack 6 meshes with the bottom of each gear 5. The bottom of each rack 6 is fixedly installed at a corresponding position on the base frame part 203.

[0029] A sliding base 7 is fixedly installed on one side of the outer wall of the radial drill base 1. The sliding base 7 has a stroke groove 701 inside, and the stroke groove 701 passes through the mounting groove 101. A sliding plate 8 is slidably connected on the sliding base 7. One end of the rotating shaft 4 passes through the stroke groove 701 to the outside of the sliding plate 8. A worm gear 9 is fixedly installed at one end of the rotating shaft 4. A worm 10 is meshed at the top of the worm gear 9. Both ends of the worm 10 are rotatably connected to bearing seats 11. The two bearing seats 11 are fixedly installed on the sliding plate 8.

[0030] A telescopic drive shaft 12 is provided on one side of the slide base 7. One end of the telescopic drive shaft 12 is connected to one end of the worm gear 10 through a coupling. A steering gear 13 is fixedly installed on one side of the radial drilling base 1. The output shaft on one side of the steering gear 13 is connected to the other end of the telescopic drive shaft 12 through a coupling.

[0031] A column 14 is fixedly welded to one side of the top of the radial drilling base 1. A second steering gear 15 is fixedly installed on the top of the column 14. A connecting shaft 16 is provided between the first steering gear 13 and the second steering gear 15. The two ends of the connecting shaft 16 are connected to the input shaft at the top of the first steering gear 13 and the output shaft at the bottom of the second steering gear 15 respectively through couplings. A rotating wheel 17 is fixedly installed on the input shaft on one side of the second steering gear 15, and several pedal rods 1701 are fixedly welded at equal intervals on the rotating wheel 17.

[0032] The working principle of the foot-operated workpiece lifting mechanism of this type of radial drill is as follows:

[0033] When the height of the workpiece platform 3 needs to be adjusted, first step on the pedal 1701 on the rotating wheel 17 to force the rotating wheel 17 to rotate. Then, through the connection of the input and output shafts of the steering gear 2 15, the connecting shaft 16 is driven to rotate. Then, through the connection of the input and output shafts of the steering gear 13, the telescopic transmission shaft 12 is driven to rotate, which in turn drives the worm gear 10 to rotate. At this time, the worm wheel 9 is driven to rotate. During the rotation of the worm wheel 9, the rotating shaft 4 is driven to rotate, which drives the two gears 5 fixedly installed on the rotating shaft 4 to rotate synchronously. This realizes the process of synchronous movement of the two gears 5 on the two racks 6 respectively. At this time, the process of raising or lowering the shear lifting platform 2 can be further realized (the specific structure and working principle of the shear lifting platform are known and publicly disclosed technologies, so they will not be described in detail here).

[0034] During the rising or falling process of the shear lifting platform 2, the rotating shaft 4 will also move forward or backward along with the two gears 5 and the ends of the two movable forks 202. At this time, the opening of the stroke groove 701 provides clearance space for the movement of the rotating shaft 4, and the slide plate 8 provides an installation position for the end of the rotating shaft 4, so that it can rotate on its own or drive the worm gear 9 and worm 10 to move synchronously. Through the connection structure of the telescopic transmission shaft 12, it does not hinder the normal output of the driving force, nor does it interfere with the movement of the worm 10.

[0035] Example 2:

[0036] In view of the above embodiment 1, further description is provided, see reference. Figure 3 and Figure 4The width of the workpiece table 3 is equal to the width of the inner wall of the mounting groove 101, and the length of the workpiece table 3 is less than the length of the mounting groove 101. This allows the workpiece table 3 to be directly stored inside the mounting groove 101 when it is placed at its lowest position, thus reducing the height of the workpiece table 3 when loading.

[0037] The width of the stroke groove 701 is greater than the outer diameter of the shaft 4, and the length of the stroke groove 701 is greater than the length of the two racks 6. This provides clearance for the movement of the shaft 4. The length of the stroke groove 701 is longer than the length of the racks 6, which facilitates the forward or backward movement of the two gears 5 and avoids interference.

[0038] The indicator rod 19 is installed on the workpiece table 3, so that the workpiece table 3 can be raised and lowered by moving the indicator rod 19. The height of the workpiece table 3 can be easily and promptly understood by the scale at the corresponding contact position of the indicator rod 19 with the scale, and the height of the workpiece table 3 can be precisely controlled by adjusting the height of the workpiece table 3.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
