Description

Technical Field

[0001] This utility model relates to the technical field of drilling machine pressing equipment, and in particular to a pressing fixture for unloading a handwheel-type radial drilling machine. Background Technology

[0002] A radial drilling machine is a branch of drilling machines, named for its horizontal arm which can rotate around the column. It is mainly used for drilling, reaming, boring, countersinking, and tapping on workpieces, including those made of graphite.

[0003] Before machining a workpiece with a radial drilling machine, the workpiece needs to be clamped. However, since different graphite materials may have different heights, and the graphite material to be clamped may also have uneven clamping surfaces, conventional clamping fixtures are difficult to effectively fix the workpiece. Utility Model Content

[0004] This application provides a handwheel-type radial drilling tool for material feeding, which can flexibly adjust the clamping height of the clamping arm and is suitable for clamping and fixing workpieces of different heights and sizes. At the same time, it can also automatically adjust the clamping direction of the universal clamping block to make it as close to the workpiece as possible, resulting in better clamping effect.

[0005] This application provides a handwheel-type radial drilling machine blanking clamping fixture, including a clamping frame, a clamping arm, and a universal clamping block. The clamping frame is fixed to the drilling machine bed, and a handwheel is installed at the top of the clamping frame. A lead screw extending vertically along the central axis is provided in the clamping frame, and the lead screw is connected to the center of the handwheel. One end of the clamping arm is threadedly engaged with the lead screw via a lead screw slider, so that when the handwheel is rotated, the clamping arm can be moved up and down by the lead screw slider based on the threaded engagement. The other end of the clamping arm is vertically connected to a connecting column, and the bottom end of the connecting column is provided with a universal ball head. The top of the universal clamping block is provided with a cavity that mates with the universal ball head, so that the universal clamping block can rotate on the universal ball head to change the clamping direction.

[0006] In one possible implementation, the connecting post has a threaded portion at a position near the middle of the extending direction, and the clamping arm has a threaded hole that mates with the threaded portion.

[0007] In one possible implementation, the universal pressure block includes a connecting shaft and a pressure plate vertically connected to the bottom of the connecting shaft, wherein the cavity is located at the top of the connecting shaft, and wherein the pressure plate protrudes from the outer ring of the connecting shaft in the radial direction of the connecting shaft.

[0008] In one possible implementation, the bottom of the pressure frame is connected to a mounting plate, and fastening bolts are installed on the mounting plate for fixing the mounting plate to the bed of the drilling machine.

[0009] In one possible implementation, the clamping arm is hinged to the lead screw slider, allowing the clamping arm to swing vertically relative to the lead screw slider. The clamping arm has a vertically extending limiting channel, within which a clamping screw is provided. The clamping screw includes an end and a stud, wherein the end engages with a T-hole on the top of the drilling machine bed to fix the clamping screw to the drilling machine bed. The stud has external threads, penetrates the limiting channel, and a clamping nut is screwed above the clamping arm to press down on the clamping arm.

[0010] In one possible implementation, the limiting channel is a waist-shaped channel that extends along the length of the clamping arm.

[0011] In one possible implementation, the top of the pressure frame is provided with a T-shaped channel, and the lead screw is provided with a T-shaped protrusion that cooperates with the T-shaped channel, the T-shaped protrusion protruding radially from the lead screw.

[0012] Beneficial effects: Compared with the prior art, the handwheel-type radial drilling blanking clamping fixture provided in this application drives the lead screw to rotate in a directional manner by rotating the handwheel. Based on the threaded engagement between the lead screw and the lead screw slider, the clamping arm and the universal clamping block move up and down. It is suitable for clamping workpieces of different heights and sizes and has a wide range of applications. In addition, the clamping arm and the universal clamping block are movably engaged through the universal ball joint on the connecting column. During the clamping process, the clamping direction of the universal clamping block can be automatically changed based on the shape of the clamping surface of the workpiece, so that the universal clamping block can make fuller contact with the workpiece and the clamping effect is better.

[0013] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0019] Those skilled in the art should understand that, in the disclosure of this specification, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0020] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0021] refer to Figures 1 to 4 This application provides a handwheel-type radial drilling machine blanking clamping fixture, including a clamping frame 10, a clamping arm 20, and a universal clamping block 30. The clamping frame 10 is fixed to the drilling machine bed 40, and a handwheel 11 is mounted on the top of the clamping frame 10. A lead screw 12 extending vertically is provided at the central axis of the clamping frame 10, and the lead screw 12 is connected to the center of the handwheel 11. Thus, rotating the handwheel 11 can drive the lead screw 12 to rotate in a specific direction. One end of the clamping arm 20 is connected to the lead screw via a lead screw slider 21. The 12 threaded engagement allows the screw slider 21 to drive the clamping arm 20 up and down based on the threaded engagement when the handwheel 11 is rotated. The other end of the clamping arm 20 is vertically connected to a connecting post 22, and the bottom end of the connecting post 22 is provided with a universal ball head 23. The top of the universal pressure block 30 is provided with a cavity 301 that mates with the universal ball head 23, so that when clamping the workpiece, the universal pressure block 30 can rotate on the universal ball head 23 and automatically change the clamping direction, thereby generating a larger contact area with the workpiece.

[0022] The handwheel-type radial drilling tooling provided in this application can adjust the clamping height of the clamping arm 20 and the universal clamping block 30 by rotating the handwheel 11 based on the height of the workpiece to be processed. This allows the tooling to clamp workpieces of different heights and sizes (such as graphite materials) on the drilling machine bed 40, making it widely applicable. In addition, based on the cooperation between the universal ball head 23 and the cavity 301, even if the clamping surface of the workpiece is uneven, the universal clamping block 30 will automatically find the clamping direction when clamping the workpiece, so that the universal clamping block 30 can make fuller contact with the workpiece and achieve better clamping effect.

[0023] In one embodiment, the connecting column 22 is provided with a threaded portion 221 at a position near the middle of the extending direction, and the clamping arm 20 is provided with a threaded hole 201 that mates with the threaded portion 221. Thus, the pressing height of the universal pressure block 30 can be adjusted by rotating the connecting column 22 based on the mating of the threaded portion 221 and the threaded hole 201. The adjustment stroke depends on the length of the threaded portion 221. This adds a fine-tuning function to the adjustment of the pressing height of the universal pressure block 30 by rotating the handwheel 11, making it more convenient to use.

[0024] In one embodiment, the universal pressure block 30 includes a connecting shaft 31 and a pressure plate 32 vertically connected to the bottom of the connecting shaft 31, wherein the cavity 301 is located at the top of the connecting shaft 31, and wherein the pressure plate 32 protrudes from the outer ring of the connecting shaft 31 in the radial direction of the connecting shaft 31 to provide a larger pressure area, thereby improving the pressure stability of the tooling.

[0025] In one embodiment, the bottom of the pressure frame 10 is connected to a mounting plate 13, and fastening bolts 14 are installed on the mounting plate 13 to fix the mounting plate 13 to the bed 40 of the drilling machine.

[0026] Although the workpiece can be clamped by moving the clamping arm 20 up and down through the lead screw slider 21 in a direct connection, this can easily create a reverse force that damages the threaded fit between the lead screw slider 21 and the lead screw 12, thereby affecting the service life of the tooling. Preferably, the clamping arm 20 is hinged to the lead screw slider 21, allowing the clamping arm 20 to swing vertically relative to the lead screw slider 21. The clamping arm 20 has a vertically extending limiting channel 202, and a clamping screw 24 is provided within the limiting channel 202. The clamping screw 24 includes an end 241 and a stud 242. The end 241 engages with a T-hole 401 on the top of the drilling machine bed 40 to fix the clamping screw 24 to the drilling machine bed 40. The stud 242 has external threads and penetrates the limiting channel 202. A clamping nut 243 is screwed above the clamping arm 20 to press down on it. During installation, the end 241 is first inserted into the drilling machine bed 40 through the T-hole 401, with the stud 242 extending vertically upwards and directly facing the limiting channel 202. Then, the handwheel 11 is rotated to slowly drive the clamping arm 20 downwards, allowing the stud 242 to pass through the limiting channel 202. Subsequently, the clamping nut 243 is screwed in above the stud 242. During use, the handwheel 11 is first rotated to move the universal clamping block 30 into position. At this time, the universal clamping block 30 is only close to but not clamping the workpiece. Then, the clamping nut 243 is rotated to make the universal clamping block 30 tightly adhere to the top of the workpiece and clamp it. During the clamping process, the clamping arm 20 will have a certain degree of sway around the rotating shaft 211 at the connecting end of the lead screw slider 21. This will offset most of the reaction force at the rotating shaft 211, thereby extending the service life of the tooling.

[0027] More preferably, the limiting channel 202 is an oblong channel, and the limiting channel 202 extends along the length direction of the clamping arm 20. In addition, the length direction of the clamping arm 20 is the same as the extension direction of the guide hole on the drilling machine bed 40. This guide hole is the vertical part of the aforementioned T-shaped hole 401. Thus, the clamping arm 20 can be pressed and locked at different points along the extension direction of the oblong channel 202, and can be flexibly adjusted according to the clamping needs.

[0028] In one embodiment, the top of the pressure frame 10 is provided with a T-shaped channel 101, and the lead screw 12 is provided with a T-shaped protrusion 121 that cooperates with the T-shaped channel 101. The T-shaped protrusion 121 protrudes radially from the lead screw 12, thereby restricting the lead screw 12 to a fixed height position based on the cooperation between the T-shaped protrusion 121 and the T-shaped channel 101, so that the lead screw 12 can only rotate in the vertical direction and cannot move up and down.

[0029] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
