Description

Technical Field

[0001] The utility model relates to the technical field of milling machine processing, in particular to a chamfering device for milling machine processing of injection molded parts. Background Art

[0002] Chamfering refers to the process of cutting the edges and corners of a workpiece into a certain slope and angle. The purpose is to facilitate the assembly of parts, remove burrs caused by machining or use other special functions. When processing rectangular workpieces, it is necessary to chamfer the twelve sides of the rectangular workpiece. In the past, when processing chamfers on a milling machine, it was necessary to use tooling of different shapes to control the angle in order to process chamfers of corresponding sizes. This method is too cumbersome and affects the processing efficiency of the milling machine. Therefore, there is an urgent need for a chamfering device for milling injection molding parts. Utility Model Content

[0003] 1. Technical Problems to be Solved by the Utility Model

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a chamfering device for injection molding milling machine processing, which has the advantage of realizing variable angle and chamfer size regulation for rectangular workpieces, and solves the problem of low efficiency caused by the need for different working coordination when chamfering workpieces in the past.

[0005] 2. Technical solution

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] A chamfering device for milling injection molded parts, the structure of which includes a milling cutter shaft, a milling cutter, a workbench, and a chamfering device fixed on the workbench. The chamfering device includes a fixed plate, a cylindrical hinged cylinder fixed on one side of the fixed plate, a mounting plate arranged on one side of the fixed plate and having a slide groove on the back of the mounting plate, and a fixing mechanism slidably connected to the inside of the slide groove.

[0008] As an optimization, the fixing mechanism includes a matching block directly connected in the middle and a clamping portion arranged at the raised parts at both ends for fixing the workpiece.

[0009] As an optimization, the clamping part includes a movable groove, a protrusion slidably connected in the movable groove and the protrusion is fixedly connected to the U-shaped plate on one side, and a cylinder is arranged at the lower end of the U-shaped plate.

[0010] As an optimization, the cylinder includes a magnet block slidably connected inside, a threaded column that cooperates with the upper U-shaped plate to compress the magnet block at the lower end to press the workpiece. The magnet block increases the friction force on the workpiece after contacting the metal injection molded part.

[0011] As an optimization, the mounting plate includes a round rod fixed on one side and hinged to the hinge tube to realize the rotation of the mounting plate, and a through hole is opened on the hinge tube, and a top screw cooperates with the thread of the through hole. After the top screw is installed, the round rod is tightened to prevent the mounting plate from rotating.

[0012] As an optimization, an active rod that cooperates with the mating block thread is fixed on the side of the mounting plate facing the slide groove. After the active rod is rotated through manual control, the mating block that cooperates with its thread can move up and down, so that the fixing mechanism connected to the mating block can be movable and adjusted for workpieces of different lengths.

[0013] As an optimization, the length of the magnet block should be greater than the spacing between the protrusion and the movable groove. The length of the magnet block is set so that when workpieces of different thicknesses are installed into the mounting plate, the protrusion fixed to the U-shaped plate can slide in the movable groove, so that the workpiece can be placed between the mounting plate and the magnet block first, and then the threaded column is turned to press the magnet block against the workpiece through the bottom end, thereby allowing the threaded rod to continuously press downward to allow the protrusion to touch the movable groove and then fix the workpiece on the mounting plate.

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the utility model has the following advantages: the utility model is a chamfering device for injection molding milling machine processing, through the mounting plate fixed on the chamfering device on the workbench, because the mounting plate is a rotatable structure and it is tightened by the top screw to the hinge cylinder to fix and limit the rotation of the mounting plate, before the installation of the rectangular workpiece, the position of the fixing mechanism on the mounting plate is preliminarily adjusted by the active rod and the matching block, and then the magnet block at the bottom is pressed to slide in the cylinder by rotating the threaded rod, and after the threaded rod is continuously rotated to press the workpiece, the friction between the magnet block and the workpiece is increased to prevent the workpiece from sliding during chamfering. In summary, the chamfering size of the workpiece is controlled by angle adjustment to improve the efficiency of chamfering. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See also Figure 1-6 A chamfering device for milling injection molded parts, the structure of which includes a milling cutter shaft 1, a milling cutter 3, a workbench 7, and a chamfering device 5 fixed on the workbench 7. The chamfering device 5 includes a fixed plate 10, a cylindrical hinge cylinder 17 fixed to one side of the fixed plate 10, a mounting plate 15 arranged on one side of the fixed plate 10 and a slide groove is opened on the back of the mounting plate 15, and a fixing mechanism 13 slidably connected to the inside of the slide groove.

[0026] In this embodiment, the fixing mechanism 13 includes a matching block 50 directly connected in the middle and clamping portions 55 provided at the raised portions at both ends for fixing the workpiece.

[0027] In this embodiment, the clamping portion 55 includes a movable groove 73 , a protrusion 70 slidably connected in the movable groove 73 and fixedly connected to a U-shaped plate 77 on one side of the protrusion 70 , and a cylinder 90 disposed at the lower end of the U-shaped plate 77 .

[0028] In this embodiment, the cylinder 90 includes a magnet block 79 slidably connected therein, and a threaded column 75 that is threadedly matched with an upper U-shaped plate 77 and uses the lower end to press the magnet block 79 against the workpiece. The magnet block 79 increases the friction force on the workpiece after contacting the metal injection molded part.

[0029] In this embodiment, the mounting plate 15 includes a round rod 301 fixed on one side and hinged to the hinge tube 17 to realize the rotation of the mounting plate 15, and a through hole is provided on the hinge tube 17, and a top screw 33 is threadedly matched with the through hole.

[0030] After the jack screw 33 is installed, the round rod 301 is tightened to prevent the mounting plate 15 from rotating.

[0031] In this embodiment, an active rod 11 threadably engaged with the engaging block 50 is fixed on the side of the mounting plate 15 facing the slide slot.

[0032] After the active rod 11 is rotated by manual control, the matching block 50 that is threadedly matched with the active rod 11 can be moved up and down, so that the fixing mechanism 13 connected to the matching block 50 can be moved to adjust workpieces of different lengths.

[0033] In this embodiment, the length of the magnet block 79 is greater than the distance between the protrusion 70 and the movable groove 73 .

[0034] The length of the magnet block 79 is set so that when workpieces of different thicknesses are installed into the mounting plate 15, the protrusion 70 fixedly connected to the U-shaped plate 77 is allowed to slide in the movable groove 73, so that the workpiece can be placed between the mounting plate 73 and the magnet block 79 first, and then the threaded column 75 is twisted to press the magnet block 79 against the workpiece through the bottom end, thereby allowing the threaded rod 75 to continuously press downward to allow the protrusion 70 to touch the movable groove 73 and fix the workpiece on the mounting plate 73.

[0035] In this embodiment, the rectangular workpiece is located at the opposite sides where the workpiece and the mounting plate 73 are in contact, and the workpiece is aligned with the top of the mounting plate 73 .

[0036] When installing the workpiece: first, the active column 11 is used to rotate and adjust the spacing between the fixing mechanism 13 and the top of the mounting plate 15, and the magnet block 79 on the fixing mechanism 13, when facing workpieces of different thicknesses, allows the protrusion 70 connected and fixed to the U-shaped plate 77 to slide in the movable groove 73, so that the workpiece can be placed between the mounting plate 73 and the magnet block 79 first, and then the threaded column 75 is twisted to press the magnet block 79 against the workpiece through the bottom end, so that the threaded rod 75 that is continuously pressed downward allows the protrusion 70 to touch the movable groove 73 and then fix the workpiece on the mounting plate 73. And because the mounting plate 13 is hinged to the articulated tube 17 through the round rod 301 fixed on one side to achieve rotation, the angle of the workpiece during chamfering is adjusted by rotation to control the chamfering size, and finally the top screw 33 is pushed into the articulated tube 17 to tighten the round rod 10 to prevent the mounting plate 13 from rotating.
