Description

Technical Field

[0001] The utility model relates to the technical field of milling machine processing, in particular to a milling machine fixture. Background Art

[0002] A milling machine is a machine tool that uses a milling cutter to process the surface of a workpiece. When drilling and other milling processes are required on a circular workpiece, the circular workpiece must first be clamped and fixed using a fixture. The fixture currently used on milling machines to clamp and fix the circular workpiece requires screwing to adjust. The screws on the fixtures on both sides can be turned to adjust the distance between the fixtures on both sides, thereby clamping and fixing the circular workpiece.

[0003] However, in this way, the screw needs to be turned repeatedly when clamping and removing the workpiece. The milling speed of the milling machine is fast, and the time for clamping and removing the workpiece is slow, which will delay the efficiency of milling multiple workpieces in sequence.

[0012] As an improvement, one end of the guide rod is provided with a protrusion that cooperates with the movable clamping block, and the protrusion is used to limit the movable clamping block.

[0013] As an improvement, the movable clamp block and the fixed clamp block are both provided with triangular clamp grooves that cooperate with the circular workpiece body.

[0014] (III) Beneficial effects

[0015] The advantage of the utility model over the prior art is that when a circular workpiece body needs to be milled, the circular workpiece body is placed between the fixed clamp block and the movable clamp block, and the grip rod can be rotated to utilize the eccentric rotating rod and the abutment block to push the abutment plate, thereby pushing the movable clamp block, and then the circular workpiece body can be clamped and fixed by the triangular clamp groove, and the movable clamp block can be reset under the action of the reset spring after the grip rod is loosened, which can shorten the time for clamping and removing the circular workpiece body and improve the milling efficiency.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a milling machine fixture includes a circular workpiece body 9 and a mounting plate 1, the mounting plate 1 is provided with mounting holes 2 arranged opposite to each other and cooperating with the milling machine, and also includes a movable clamping block 5 and a vertical plate 3 fixedly arranged on the upper end of the mounting plate 1, one side of the vertical plate 3 is fixedly connected with a fixed clamping block 4, one side of the fixed clamping block 4 is fixedly connected with a relatively arranged guide rod 7, the movable clamping block 5 is provided with relatively arranged through holes 8 respectively cooperating with the guide rods 7 on both sides, a soft pad cooperating with the circular workpiece body 9 is adhered to the mounting plate 1 below the fixed clamping block 4 and the movable clamping block 5 to avoid collision between the circular workpiece body 9 and the mounting plate 1, the movable clamping block 5 and the fixed clamping block 4 are both provided with a triangular clamping groove 6 cooperating with the circular workpiece body 9, which can clamp and fix circular workpiece bodies 9 of different sizes.

[0025] Through the above structure, the circular workpiece body 9 can be clamped and fixed by using the movable clamp block 5 and the fixed clamp block 4. How to save the clamping time? The specific structure is as follows:

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the mounting plate 1 is provided with an eccentric structure for pushing the movable clamping block 5, and the eccentric structure includes a bearing seat 11 fixedly arranged on the upper end of the mounting plate 1, and an eccentric rotating rod 12 is provided on the bearing seat 11, and a stop block 13 is fixedly connected to the eccentric rotating rod 12, and a stop plate 10 cooperating with the stop block 13 is fixedly connected to one side of the movable clamping block 5, and a gripping rod 14 is fixedly connected to the stop block 13, and a non-slip rubber sleeve is sleeved on the gripping rod 14 to facilitate the rotation of the stop block 13, and a limit nut 16 cooperating with the stop block 13 is threadedly connected to the eccentric rotating rod 12 to improve the stability of the stop block 13.

[0027] Through the above structure, the eccentric structure is used to facilitate pushing the movable clamping block 5 to clamp and fix the circular workpiece body 9.

[0028] Embodiment 2

[0029] like Figure 1 and Figure 2 As shown, the fixed clamp block 4 is provided with relatively arranged return springs 15 respectively surrounding the guide rods 7 on both sides, one end of the return spring 15 relative to the fixed clamp block 4 is connected to the movable clamp block 5, and one end of the guide rod 7 is provided with a protrusion that cooperates with the movable clamp block 5, and the protrusion is used to limit the movable clamp block 5.

[0030] Through the above structure, when released, the return spring 15 can drive the movable clamping block 5 to move, and the protrusion on the guide rod 7 can prevent the movable clamping block 5 from being separated from the guide rod 7 when moving.

[0031] When the utility model is implemented, the mounting plate is fixedly mounted on the milling machine by using the mounting hole. When the circular workpiece body needs to be milled, it is placed between the fixed clamping block and the movable clamping block. Then the staff grasps the gripping rod and rotates it. Under the action of the eccentric rotating rod, the block can rotate with the eccentric rotating rod as the axis. During the rotation of the block, the block can contact the plate and push the plate to move, so that the movable clamping block can be pushed to move along the guide rod. At this time, the reset spring is in a compressed state.

[0032] When the triangular clamp groove is close to the surface of the circular workpiece body, the circular workpiece body is clamped and fixed. At this time, the worker holds the grip rod and keeps the grip rod motionless to mill the circular workpiece body. After milling is completed, the grip rod is released, and under the elastic force of the reset spring on the movable clamp block, the circular workpiece body can be removed from between the fixed clamp block and the movable clamp block, and then the next circular workpiece body can be clamped and fixed. This saves time in the process of clamping and removing the circular workpiece body, and can improve the efficiency of milling multiple circular workpiece bodies in sequence.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0035] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
