Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to an inclined plane positioning device for CNC milling machine machining. Background Technique

[0002] A CNC milling machine is also called a milling machine controlled by electronic digital signals. A CNC milling machine is an automatic processing device developed on the basis of a general milling machine. The processing technologies of the two are basically the same, and the structures are also somewhat similar. CNC milling machines are divided into two categories: those without a tool magazine and those with a tool magazine. Among them, the CNC milling machine with a tool magazine is also called a machining center. With the development of science and technology and the rise and continuous maturity of world advanced manufacturing technologies, higher requirements are put forward for CNC machining technologies; the application of technologies such as ultra-high-speed cutting and ultra-precision machining has put forward higher performance indicators for the CNC system, servo performance, spindle drive, and machine tool structure of CNC machine tools; with the development of microelectronics and computer technologies, the performance of CNC systems is becoming increasingly perfect, and the application fields of CNC technologies are expanding day by day. A CNC milling machine is a numerically controlled machine tool with very strong processing functions. Currently, the rapidly developed machining centers, flexible manufacturing units, etc. are all generated on the basis of CNC milling machines and CNC boring machines, and both are inseparable from the milling method.

[0003] For the existing CNC milling machine, a device for clamping and positioning the workpiece is required during machining. However, the traditional clamping and positioning clamping plates cannot be disassembled and replaced, and cannot adapt to workpieces of different regular shapes. If the situation where two sets of clamping plates cannot fit occurs, there will be a small contact surface and unstable clamping. Therefore, those skilled in the art provide an inclined plane positioning device for CNC milling machine machining to solve the problems raised in the above background technique. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides an inclined plane positioning device for CNC milling machine machining, which includes an adjusting fixed rod assembly. Two extension plates are sleeved on the upper end of the adjusting fixed rod assembly. The left end of the extension plate is fixedly installed with the same fixing plate, and positioning components are symmetrically arranged up and down on the left end face of the fixing plate;

[0005] The extension plate includes an extension long plate, a sliding long hole, and a connecting block. A sliding long hole is opened in the middle of the upper end of the extension long plate, and the extension long plate is movably sleeved on the adjusting fixed rod assembly through the sliding long hole;

[0006] The positioning component includes a sleeve plate seat, a fixed slot hole, a resisting rod, a fixed slot, a trapezoidal plate, an angle code, and a fixing bolt. Sleeve plate seats are symmetrically arranged up and down on the left end face of the fixing plate. A fixed slot is opened on the right side inside the sleeve plate seat. A slidable trapezoidal plate is arranged in the fixed slot. Fixed slot holes are symmetrically opened on the front and rear end walls of the left end of the fixed slot. A freely slidable resisting rod is arranged in the fixed slot hole, and the right end of the resisting rod corresponds to the inclined surface of the side end of the trapezoidal plate.

[0007] Preferably, a connecting block is fixedly installed at the left end of the extending long plate, and the connecting block fixedly installs the extending long plate on the fixing plate.

[0008] Preferably, the adjusting fixed rod assembly includes a fixed rod seat, a positioning bolt cap, a support ring, a limiting spring, a spring seat, and a reset spring. The upper end of the fixed rod seat passes through the sliding long hole and is correspondingly bolted to the positioning bolt cap, and a support ring is arranged on the sliding long hole of the upper extending long plate.

[0009] Preferably, a limiting spring is fixedly installed on the support ring, and the limiting spring is correspondingly arranged with the positioning bolt cap. By using the limiting pressure deformation of the limiting spring by the positioning bolt cap, the sliding of the fixed rod seat in the sliding long hole is restricted. Spring seats are symmetrically arranged between the upper extending long plate and the lower extending long plate.

[0010] Preferably, a reset spring is fixedly installed between the spring seats. Through the elastic deformation of the reset spring, the interference fit caused by the deformation pressure of the limiting spring is prevented, resulting in subsequent deviation of the positioning and limiting, ensuring the limiting stability of the positioning device and increasing the practicability.

[0011] Preferably, a plurality of angle codes are symmetrically arranged at the upper and lower ends of the sleeve plate seat, and fixing bolts are arranged on the angle codes. The sleeve plate seat is fixed on the fixing plate by tightening with the fixing bolts in cooperation with the angle codes.

[0012] The technical effects and advantages of the present utility model are as follows:

[0013] 1. When the present utility model is in use, by pushing the extending long plate, the sliding long hole corresponds to the fixed rod seat for movement, so that the abutting rod contacts the inclined surface of the workpiece. At this time, according to the contour shape of the inclined surface of the workpiece, the abutting rod will freely slide in the fixed slot hole, so that the inclined surface at the side end of the trapezoidal plate is restricted by the abutting rod, and the trapezoidal plate slides in the fixed slot, and further the abutting rod abuts against the inclined surface of the workpiece, providing a good fixing effect for different-shaped special-shaped parts.

[0014] 2. When the present utility model is in use, rotate the positioning bolt cap. By using the limiting pressure deformation of the limiting spring by the positioning bolt cap, the sliding of the fixed rod seat in the sliding long hole is restricted, and the elastic deformation of the reset spring is used to prevent the interference fit caused by the deformation pressure of the limiting spring, resulting in subsequent deviation of the positioning and limiting, ensuring the limiting stability of the positioning device and increasing the practicability.

[0023] See also Figures 1 to 3 In this embodiment, a bevel positioning device for CNC milling machine processing is provided, including an adjustable fixed rod assembly 2, wherein two sets of extension plates 1 are sleeved on the upper end of the adjustable fixed rod assembly 2, and the same fixed plate 3 is fixedly installed on the left end of the extension plate 1, and the left end surface of the fixed plate 3 is symmetrically provided with positioning assemblies 4 above and below;

[0024] The extension plate 1 comprises an extension long plate 11, a sliding long hole 12 and a connecting block 13. The sliding long hole 12 is provided in the middle of the upper end of the extension long plate 11. The extension long plate 11 is movably sleeved on the adjustment fixed rod assembly 2 through the sliding long hole 12. The left end of the extension long plate 11 is fixedly mounted with a connecting block 13. The connecting block 13 fixes the extension long plate 11 on the fixed plate 3.

[0025] The adjusting fixed rod assembly 2 includes a fixed rod base 21, a positioning bolt cap 22, a support ring 23, a limiting spring 24, a spring seat 25 and a return spring 26. The upper end of the fixed rod base 21 passes through the sliding long hole 12 and is correspondingly bolted to the positioning bolt cap 22. A support ring 23 is arranged on the sliding long hole 12 of the upper extension long plate 11. A limiting spring 24 is fixedly installed on the support ring 23. The limiting spring 24 is correspondingly arranged with the positioning bolt cap 22. By the limiting pressure deformation of the limiting spring 24 by the positioning bolt cap 22, the sliding of the fixed rod base 21 in the sliding long hole 12 is restricted. Spring seats 25 are symmetrically arranged between the upper extension long plate 11 and the lower extension long plate 11. A return spring 26 is fixedly installed between the spring seats 25. Through the elastic deformation of the return spring 26, the interference fit caused by the deformation pressure of the limiting spring 24 is prevented, resulting in subsequent deviation of positioning and limiting;

[0026] The positioning assembly 4 includes a sleeve plate seat 41, a fixed slot hole 42, a resisting rod 43, a fixed slot 44, a trapezoidal plate 45, an angle code 46 and a fixing bolt 47. Sleeve plate seats 41 are symmetrically arranged on the upper and lower sides of the left end face of the fixed plate 3. A plurality of angle codes 46 are symmetrically arranged at the upper and lower ends of the sleeve plate seat 41. A fixing bolt 47 is arranged on the angle code 46. The sleeve plate seat 41 is fixed on the fixed plate 3 by fastening with the fixing bolt 47 and the angle code 46. A fixed slot 44 is opened on the right side inside the sleeve plate seat 41. A slidable trapezoidal plate 45 is arranged in the fixed slot 44. Fixed slot holes 42 are symmetrically opened on the front and rear end walls of the left end of the fixed slot 44. A freely slidable resisting rod 43 is arranged in the fixed slot holes 42. The right end of the resisting rod 43 is correspondingly arranged with the side end inclined surface of the trapezoidal plate 45.

[0027] The working principle of the present utility model is:

[0028] When the present utility model is used, by arranging an inclined surface positioning device at the left and right ends of the milling machine, the extension long plate 11 is pushed, so that the sliding long hole 12 and the fixed rod base 21 are correspondingly movable, thereby enabling the resisting rod 43 to contact the inclined surface of the workpiece. At this time, according to the contour shape of the inclined surface of the workpiece, the resisting rod 43 will freely slide in the fixed slot hole 42, so that the side end inclined surface of the trapezoidal plate 45 is restricted by the resisting rod 43, enabling the trapezoidal plate 45 to slide in the fixed slot 44, and further enabling the resisting rod 43 to be pressed against the inclined surface of the workpiece, providing a good fixing effect for different-shaped special-shaped parts. Then, the positioning bolt cap 22 is rotated. By the limiting pressure deformation of the limiting spring 24 by the positioning bolt cap 22, the sliding of the fixed rod base 21 in the sliding long hole 12 is restricted, and the elastic deformation of the return spring 26 is used to prevent the interference fit caused by the deformation pressure of the limiting spring 24, resulting in subsequent deviation of positioning and limiting, ensuring the limiting stability of the positioning device and increasing the practicability.
