Description

Technical Field

[0001] This utility model belongs to the field of workpiece clamping devices, and specifically relates to a workpiece clamping device for a radial drilling machine. Background Technology

[0002] Currently, radial drilling machines are drilling machines in which the radial arm can rotate and move up and down around the column, and the spindle box usually moves horizontally on the radial arm. When machining holes on a vertical drilling machine, the alignment of the tool and the workpiece is achieved by moving the workpiece, which is obviously very inconvenient for some large and heavy workpieces. However, radial drilling machines can use the position of the tool axis to achieve alignment, which brings great convenience to machining holes on large and heavy workpieces in single-piece and small-batch production.

[0003] However, when using existing radial drilling machines, a corresponding clamping device is required in order to clamp the workpiece better. However, the existing clamping device can generally only clamp and position the front and rear ends or left and right ends of the workpiece. When clamping and positioning thinner parts, relying on clamping the outside of the workpiece can easily cause the workpiece to bend and deform.

[0004] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a workpiece clamping device for a radial drilling machine to solve the problem that existing clamping devices can generally only clamp and position the front and rear ends or left and right ends of the workpiece. However, when clamping and positioning thinner parts, relying on clamping the outside of the workpiece can easily cause the workpiece to bend and deform. Utility Model Content

[0005] This utility model proposes a workpiece clamping device for a radial drilling machine, which solves the problem that existing clamping devices can generally only clamp and position the front and rear ends or left and right ends of the workpiece. However, when clamping and positioning thinner parts, relying on clamping the outside of the workpiece can easily cause bending deformation.

[0006] The technical solution of this utility model is implemented as follows: A workpiece clamping device for a radial drilling machine includes: a base plate, which is arranged longitudinally, and there are two base plates arranged in a straight line array. Both base plates have through holes arranged in a straight line array inside, which are guide holes. The guide holes and the base plates together form a guide structure. A screw hole is provided on the top surface of the base plate, and a positioning bolt is screwed into the screw hole. Two cylindrical lower support rods are fixedly connected in a straight line array on the top surface of each base plate. A circular cross-section lower pad is fixedly connected to the top surface of the lower support rod, and a workpiece is placed on the top of the lower pad. A pressure plate is slidably connected to a guide groove via a slider fixedly connected to its outer surface. Two cylindrical upper support rods are fixedly connected in a straight line array on the bottom surface of each pressure plate. A circular cross-section upper pad is fixedly connected to the bottom surface of the upper support rod. The upper support rods and upper pads are located directly above the lower support rods and lower pads. The upper support rods and upper pads together form a pressing and limiting structure for the workpiece.

[0007] In a preferred embodiment, a guide rod is inserted into the guide hole. There are two guide rods, and a cylindrical support is fixedly connected to the bottom end of each guide rod.

[0008] In a preferred embodiment, both the guide rod and the support column have bidirectional through mounting holes on both the upper and lower sides, and the outer circumferential surface of the guide rod also has positioning holes arranged in a linear array.

[0009] In a preferred embodiment, a longitudinally arranged guide is fixedly connected to the top surface of the substrate, and the guide is perpendicular to the substrate.

[0010] In a preferred embodiment, the longitudinal groove in the guide frame is a guide groove, and a longitudinally arranged servo push rod is fixedly connected inside the guide groove.

[0011] In a preferred embodiment, a pressure plate is fixedly connected to the bottom end face of the servo push rod. The pressure plate is arranged longitudinally, and a slider is fixedly connected to the outer side of the pressure plate.

[0012] After using the above technical solution, the beneficial effects of this utility model are:

[0013] 1.

In this utility model, by providing an upper support rod and an upper pad that are fixedly connected to the bottom end face of the pressure plate, and the upper support rod and upper pad that are fixedly connected to the top end face of the substrate, the upper and lower ends of the thin workpiece can be clamped and positioned, thereby making it easier to perform subsequent drilling processing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-6 As shown, a workpiece clamping device for a radial drilling machine includes: a base plate 2, which is arranged longitudinally, and there are two base plates 2 arranged in a straight line array. Both base plates 2 have through holes arranged in a straight line array inside, which are guide holes 201. The guide holes 201 and the base plates 2 together form a guide structure. A screw hole is provided on the top surface of the base plate 2, and a positioning bolt 202 is screwed into the screw hole. Two cylindrical lower support rods 203 are fixedly connected in a straight line array on the top surface of each base plate 2. A circular cross-section structure is fixedly connected to the top surface of the lower support rods 203. The lower pad 204 has a workpiece 307 placed on its top. The pressure plate 303 is slidably connected to the guide groove 301 by a slider 304 fixedly connected to its outer surface. Two cylindrical upper support rods 305 are fixedly connected in a straight line array on the bottom surface of each pressure plate 303. An upper pad 306 with a circular cross-section is fixedly connected to the bottom surface of the upper support rod 305. The upper support rods 305 and the upper pads 306 are located directly above the lower support rods 203 and the lower pad 204. The upper support rods 305 and the upper pads 306 together form a pressing and limiting structure for the workpiece 307.

[0025] The guide rod 1 is inserted into the guide hole 201. There are two guide rods 1, and a cylindrical support column 101 is fixedly connected to the bottom end of both guide rods 1. The guide rod 1 and the support column 101 are provided with bidirectional through mounting holes 102 on both the upper and lower sides. The guide rod 1 is also provided with positioning holes 103 in a straight array on the outer circumference of the guide rod 1.

[0026] Among them, a longitudinally arranged guide frame 3 is fixedly connected to the top surface of the substrate 2. The guide frame 3 is perpendicular to the substrate 2.

[0027] When using a radial drilling machine, the guide rod 1 is placed on the machining table of the radial drilling machine using the support column 101 on its bottom end face, and is fixed by bolts passing through the mounting holes 102 in the support column 101 and the guide rod 1. Then, according to the different specifications of the current workpiece 307, the lateral position of the base plate 2 that is slidably connected to the outside of the guide rod 1 is adjusted. After the lateral position is adjusted, the positioning bolt 202 is fixed and limited by passing through the base plate 2 and the positioning hole 103 in the guide rod 1 in sequence.

[0028] Then, by placing the workpiece 307 on the lower pad 204 located on the top surface of the lower support rod 203, and simultaneously activating the servo push rod 302 installed in the guide groove 301 to push the pressure plate 303 downward, the pressure plate 303 drives the upper support rod 305 and the upper pad 306 to move downward, and performs an automated clamping and positioning operation on the workpiece 307 placed on the lower pad 204, and then the subsequent drilling operation can be carried out.
