Description

Technical Field

[0001] This utility model relates to the field of radial drilling machines, and in particular to an automatic workpiece clamping device for radial drilling machines. Background Technology

[0002] Radial drilling machines are a common type of metalworking machine tool. When using them, in order to ensure that the workpiece does not move or shake during the drilling process, a clamping device is generally required to clamp the workpiece to prevent it from sliding during processing.

[0003] Existing technology uses two electric push rods to drive two clamping plates to approach and clamp the workpiece from the left and right sides. When drilling the workpiece, a large amount of waste chips are generated. The waste chips will fall on the top of the workpiece placement table, making the placement surface uneven. This will affect the stability of subsequent workpiece placement, making it easy for the workpiece to be unstable and causing deviations in drilling, resulting in low drilling accuracy. Utility Model Content

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example 1, referring to Figures 1-4 This is the first embodiment of the present invention. This embodiment provides an automatic workpiece clamping device for a radial drilling machine, which can clamp the workpiece while cleaning the waste on the top of the placement table 12, so that the workpiece can be placed stably on the top of the placement table 12, resulting in a more stable clamping and fixing effect. It includes a clamping component, including an operating table 10. The top of the operating table 10 is provided with the radial drilling machine body 11. The placement table 12 is fixedly connected to the top of the operating table 10. Two support frames 13 are fixedly connected to the top of the operating table 10. Electric push rods 14 are fixedly connected inside the two support frames 13. The placement table 12 is provided with a clamping component 15.

[0023] The clamping assembly 15 includes two clamping plates 151, which are fixedly connected to the output ends of two electric push rods 14. Anti-slip pads 152 are fixedly connected to the inner side of each clamping plate 151, and L-shaped pressure plates 153 are fixedly connected to the bottom of each clamping plate 151. Two air chambers 154 are opened inside the placement platform 12. Four springs 155 are fixedly connected inside the placement platform 12. A push plate 156 is fixedly connected to the end of each spring 155 away from the placement platform 12. A push rod 157 is fixedly connected to the side of the push plate 156 away from the spring 155. A sealing ring 158 is fixedly connected to the outside of the push plate 156. Two air supply pipes 159 are fixedly connected inside the placement platform 12. An air blowing head 1510 is fixedly connected to the end of each air supply pipe 159 away from the air chamber 154. A collection frame 1511 is inserted into the placement platform 12.

[0024] Specifically, the push plate 156 moves inside the air chamber 154 to compress the air. The air is then blown out through the air supply pipe 159 and the air blower 1510. The blown airflow blows and cleans the waste on the top of the placement table 12, making it easier for the workpiece to be placed stably on the top of the placement table 12 and for subsequent clamping and fixing.

[0025] Furthermore, the bottom inner side of the blowing head 1510 is an inclined surface, and the bottom end of the inclined surface is flush with the top of the placement platform 12. The end of the air supply pipe 159 away from the blowing head 1510 is connected to the air chamber 154.

[0026] The outer side of the sealing ring 158 is in contact with the inner wall of the air chamber 154, the push rod 157 is slidably connected inside the placement platform 12, and the L-shaped pressure plate 153 corresponds to the position of the push rod 157.

[0027] In this process, the L-shaped pressure plate 153 presses against the push rod 157, at which point the push rod 157 drives the push plate 156 to move inside the air chamber 154 to compress the air, thereby causing the airflow.

[0028] In use, the two electric push rods 14 are activated synchronously, driving the two clamping plates 151 to move synchronously towards the center. The springs 155 are initially in a stretched state. At this time, the push plate 156, under the action of the two springs 155, drives the push rod 157 to protrude from the placement platform 12 and abut against the L-shaped pressure plate 153. Therefore, when the clamping plates 151 move, they drive the L-shaped pressure plate 153 to squeeze the push rod 157. At this time, the push rod 157 drives the push plate 156 to move inside the air chamber 154. Initially, there is air inside the air chamber 154. The movement of the push plate 156 inside the air chamber 154 compresses the air. The air passes through the air supply pipe 15 9. Air is ejected through the blowing head 1510, causing the airflow to blow away the debris on the top of the placement table 12. The debris falls into the collection frame 1511 through the drop chute, keeping the top of the placement table 12 clean. Then, the workpiece is placed between the two clamping plates 151 on the top of the placement table 12. The two clamping plates 151 clamp the workpiece under the action of the two electric push rods 14. The anti-slip pad 152 is placed between the workpiece and the clamping plates 151 to make the clamping more stable. When the workpiece is wide, the electric push rods 14 can be activated first to move the air to clean the top of the placement table 12. After that, the electric push rods 14 can be activated to clean the top of the placement table 12. After the push rod 14 resets the clamping plate 151, the workpiece is placed on top of the placement table 12, allowing the two clamping plates 151 to clamp once without load. When the workpiece width is small, the workpiece can be placed directly on top of the placement table 12 after cleaning. This allows for cleaning of the top of the placement table 12 while clamping the workpiece, preventing debris from scattering on top of the placement table 12 and affecting the stability of subsequent workpiece placement. Unstable workpiece clamping can lead to drilling deviations and low drilling accuracy. After drilling is completed, the clamping plates 151 are moved away from the workpiece to remove it. 51 drives the L-shaped pressure plate 153 away from the push rod 157, and the spring 155 rebounds, causing the push plate 156 to slowly reset. At this time, air enters the air chamber 154 through the air blowing head 1510 and the air supply pipe 159 until the spring 155 drives the push rod 157 to fully reset and re-abut against the L-shaped pressure plate 153. During this process, the spring 155 drives the push plate 156 to move slowly, so that the air blowing head 1510 draws air more slowly. Even if there are debris on the placement table 12, the bottom inner side of the air blowing head 1510 is inclined and has a large friction, so the debris will not enter the air chamber 154 through the air supply pipe 159.

[0029] Example 2, refer to Figure 1 , Figure 5 This is the second embodiment of the present utility model. Unlike the previous embodiment, this embodiment provides an anti-blowing component for the automatic workpiece clamping device of the radial drilling machine based on the first embodiment. This solves the problem that when the airflow blows the waste chips, they are easily blown onto the operating table 10. It includes an anti-blowing component, including a baffle 20, which is rotatably connected inside the placement table 12.

[0030] The baffle 20 has two latching slots 21 inside, and a damping shaft 22 is rotatably connected inside the baffle 20. A support plate 23 is fixedly connected to the outside of the damping shaft 22. Specifically, the support plate 23 shields the waste debris, preventing excessive blowing of the waste debris by the airflow, thus improving the waste debris collection effect.

[0031] Furthermore, the end of the support plate 23 away from the damping shaft 22 abuts against the inside of the placement groove of the baffle 20, and two fastening grooves 21 are provided on the left and right sides of the support plate 23.

[0032] The placement platform 12 has a drop trough inside, and the drop trough corresponds vertically to the collection frame 1511. The end of the baffle 20 away from the damping shaft 22 is connected to the drop trough.

[0033] When in use, before drilling the workpiece, pull the baffle 20 to rotate it. Then, insert two fingers into the two latches 21 to latch the support plate 23, so that the support plate 23 rotates and there is an angle between it and the baffle 20. Adjust the angle until the end of the support plate 23 away from the damping shaft 22 abuts against the inside of the baffle 20 placement slot on the placement table 12. At this time, the baffle 20 is tilted and the angle is fixed. At the same time, the end of the baffle 20 away from the damping shaft 22 is connected to the drop trough. The drop trough corresponds to the collection frame 1511, so that when the airflow blows the waste chips into the air blowing head 1510 through the drop trough, the waste chips will not fall to the top of the operating table 10 under the blowing of the airflow, so that the waste chip collection effect is better.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
