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 chuck-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 clamping fixture for unloading workpieces in a claw-type radial drilling machine. It can flexibly adjust the clamping height of the clamping arm, making it suitable for clamping and fixing workpieces of different heights and sizes. At the same time, it can automatically adjust the clamping direction of the universal clamping block to make it as close to the workpiece as possible, resulting in a better clamping effect.

[0005] This application provides a clamping fixture for unloading material in a chuck-type radial drilling machine, including a clamping column, a clamping arm, and a universal clamping block. The clamping column extends vertically and is fixed to the drilling machine bed. The side of the clamping column has evenly spaced teeth along its vertical direction. A movable block is fitted onto the clamping column. One end of the movable block near the teeth is hinged to a movable jaw that meshes with the teeth. The other end of the movable block away from the teeth is connected to the clamping arm via a transition block, so that when the movable jaw is rotated, the clamping arm can be moved up and down based on the meshing relationship via the transition block. The other end of the clamping arm is vertically connected to a connecting column. The bottom end of the connecting column has a universal ball joint. The top of the universal clamping block has a cavity that mates with the universal ball joint, allowing the universal clamping block to rotate on the universal ball joint to change the clamping direction.

[0006] In one possible implementation, the movable claw is hinged to the moving block via a first rotating shaft. The movable claw includes a rotating part sleeved on the first rotating shaft, a locking tooth connected to the inner end of the rotating part and meshing with the teeth, and a rotating handle connected to the outer end of the rotating part. The moving block has a clearance groove for the movable claw to rotate up and down. The moving block is also equipped with a tightening screw to tighten and fix the moving block to the pressure column after it has moved up and down into place.

[0007] In one possible implementation, the movable block is a square sleeve structure, and the tightening screw is located on the surface adjacent to the face of the teeth.

[0008] In one possible implementation, the movable block is connected to an mounting handle above the rotating handle.

[0009] 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.

[0010] 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.

[0011] In one possible implementation, the clamping arm is hinged to the adapter block, allowing the clamping arm to swing vertically relative to the adapter block. The clamping arm has a vertically extending limiting channel, within which a clamping screw is installed. 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 onto the upper part of the clamping arm to press down on the clamping arm.

[0012] In one possible implementation, the limiting channel is a waist-shaped channel that extends along the length of the clamping arm.

[0013] Beneficial effects: Compared with the prior art, the clamping fixture for cutting material in the chuck-type radial drilling machine provided in this application is equipped with a clamping column, a clamping arm, and a universal clamping block. A movable block is sleeved on the clamping column, and a movable chuck is hinged to the movable block and meshes with the teeth on the clamping column. By rotating the movable chuck, the clamping arm and the universal clamping block can be moved up and down based on the meshing relationship. This allows workpieces of different heights to be clamped and fixed on the drilling machine, which has a wide range of applications. In addition, the clamping arm is movably engaged with the universal clamping block through the universal ball joint on the connecting column. During the clamping process, the universal clamping block will automatically change the clamping direction 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.

[0014] These and other objects, features and advantages of this utility model will be fully realized through the following detailed description. Attached Figure Description

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.

[0021] 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.

[0022] 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.

[0023] refer to Figures 1 to 5This application provides a clamping fixture for unloading a chuck-type radial drilling machine, including a clamping column 10, a clamping arm 20, and a universal clamping block 30. The clamping column 10 extends vertically and is fixed to the drilling machine bed 40. The side of the clamping column 10 is evenly provided with teeth 11 along the vertical direction, and a movable block 50 is fitted onto the clamping column 11. The end of the movable block 50 near the teeth 11 is hinged to a movable chuck 51 that meshes with the teeth 11. The end of the movable block 50 away from the teeth 11 is connected via... The adapter block 52 connects to the clamping arm 20 so that when the movable jaw 51 is rotated, the clamping arm 20 can be moved up and down through the adapter block 52 based on the meshing relationship. In addition, the other end of the clamping arm 20 is vertically connected to the connecting post 21, and the bottom end of the connecting post 21 is provided with a universal ball head 22. The top of the universal pressure block 30 is provided with a cavity 301 that mates with the universal ball head 22, so that the universal pressure block 30 can rotate on the universal ball head 22 to change the clamping direction, thereby generating a larger contact area with the workpiece.

[0024] Therefore, the clamping fixture for cutting material in the chuck-type radial drilling machine provided in this application can, on the one hand, drive the clamping arm 20 and the universal clamping block 30 to move up and down based on the meshing relationship by rotating the movable chuck 51, which is suitable for clamping and fixing workpieces of different heights and sizes on the drilling machine and has a wide range of applications; on the other hand, since the bottom end of the connecting column 21 is in movable cooperation with the universal clamping block 30 through the universal ball head 22, even if the clamping surface of the workpiece is not flat, the universal clamping block 30 will be forced to automatically change the clamping direction during the clamping process, so that it can make more full contact with the workpiece and the clamping effect is better.

[0025] In one embodiment, the movable pawl 51 is hinged to the movable block 50 via a first rotating shaft 511. The movable pawl 51 includes a rotating portion 512 sleeved on the first rotating shaft 511, a pawl 513 connected to the inner end of the rotating portion 512 and meshing with the teeth 11, and a rotating handle 514 connected to the outer end of the rotating portion 512. This allows for easier rotation of the movable pawl 51 via the rotating handle 514. Furthermore, the movable block 50 has an opening for the... The movable jaw 51 has a vertically rotating clearance groove 501, which limits the movable jaw 51 from above and below, thereby limiting the vertical rotation stroke of the movable jaw 51 and preventing the jaw tooth 513 from disengaging from the tooth 11. In addition, the movable block 50 is also equipped with a tightening screw (not shown in the figure) to tighten and fix the movable block 50 onto the pressure column 10 after the movable block 50 has moved into position, thereby ensuring that the pressure arm 20 is always kept at the adjusted height position.

[0026] More preferably, the movable block 50 is a square sleeve structure, and correspondingly, the pressure column 10 is a square column. The tightening screw is located on the surface adjacent to the face of the tooth 11, which can improve the stability of the tightening screw in fixing the movable block 50, and avoid the possibility of damaging the tooth 11 by tightening it, or the problem of unreliable tightening.

[0027] In one embodiment, the movable block 50 is connected to an installation handle 53 above the rotating handle 514, thereby facilitating the installation and removal of the movable block 50 on the pressure column 10.

[0028] In one embodiment, the connecting column 21 has a threaded portion 211 at a position near the middle of the extending direction, and the clamping arm 20 has a threaded hole 201 that mates with the threaded portion 211. This allows the clamping height of the universal clamping block 30 to be adjusted by rotating the connecting column 21 based on the mating of the threaded portion 211 and the threaded hole 201. The adjustment stroke depends on the length of the threaded portion 211. This adds a fine-tuning function to the adjustment of the clamping height of the universal clamping block 30 by rotating the movable jaw 51, making it more convenient to use.

[0029] 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, so as to provide a larger pressure area and thereby improve the pressure stability of the tooling.

[0030] Although the workpiece can be clamped by moving the clamping arm 20 up and down through the adapter block 52 in a direct connection manner, this can easily create a reverse force that damages the meshing relationship between the clamping teeth 513 and the teeth 11, thereby affecting the service life of the tooling. In one embodiment, the clamping arm 20 is hinged to the adapter block 52, allowing the clamping arm 20 to swing vertically relative to the adapter block 52. The clamping arm 20 has a vertically extending limiting channel 202, and a clamping screw 23 is provided within the limiting channel 202. The clamping screw 23 includes an end 231 and a stud 232. The end 231 engages with a T-hole 401 on the top of the drilling machine bed 40 to fix the clamping screw 23 to the drilling machine bed 40. The stud 232 has external threads and penetrates the limiting channel 202. A clamping nut 24 is screwed above the clamping arm 20, allowing the clamping arm 20 to be pressed down by the clamping nut 24. During installation, the end 231 is first inserted into the drilling machine bed 40 through the T-hole 401, with the stud 232 extending vertically upwards and directly facing the limiting channel 202. Then, the movable jaw 51 is rotated to slowly drive the clamping arm 20 downwards, allowing the stud 232 to pass through the limiting channel 202. Finally, the clamping nut 24 is screwed in above the stud 232. During use, the movable jaw 51 is first rotated to move the universal clamping block 30 into position. At this point, the universal clamping block 30 is only close to, but not yet clamping, the clamping nut 24 is then rotated to make the universal clamping block 30 tightly adhere to the top of the workpiece and clamp it. During clamping, the clamping arm 20 will wobble slightly around the rotating shaft 521 at the connecting end of the adapter block 52. This wobble will offset most of the reaction force at the rotating shaft 521, thereby extending the service life of the tooling.

[0031] In one embodiment, the limiting channel 202 is a waist-shaped 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 waist-shaped channel 202, and can be flexibly adjusted according to the clamping needs.

[0032] 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.
