Description

Technical Field

[0001] This utility model relates to the field of milling machine processing technology, specifically to a milling machine mold clamping mechanism. Background Technology

[0002] A milling machine is a machine tool used to process various shapes such as planes, inclined planes, concave and convex surfaces, and grooves. It is widely used in industries such as machinery manufacturing, mold making, automobile manufacturing, and aerospace. During milling, the device used to fix the mold ensures machining accuracy and safety. Common clamping mechanisms include mechanical clamping, hydraulic clamping, and pneumatic clamping.

[0003] When a milling machine is used to clamp a mold, the clamping position of the mold is generally relatively fixed. Once the mold is clamped, the clamping position cannot be changed. However, the milling machine may overlap with the clamping position. If the clamping position cannot be changed, the clamping position of the mold cannot be machined in order to fix the mold in place.

[0004] Therefore, it is necessary to design a milling machine mold clamping mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping mechanism for milling machine molds, which solves the technical problems mentioned in the background art.

The tops of the two mounting plates are rotatably connected to a first rotating shaft and a second rotating shaft via bearings. The bottom end of one of the first rotating shafts penetrates the interior of the second connecting member, and the bottom end of both the first and second rotating shafts is fixedly sleeved with a synchronous pulley. The two synchronous pulleys are connected together by a toothed groove and a synchronous pulley is also sleeved on them. The first connector has a servo motor fixedly connected to the top of its inner cavity, and the output shaft of the servo motor is fixedly connected to the bottom end of the second rotating shaft in the inner cavity of the second connector. Gears are fixedly sleeved on the outer surfaces of the two first rotating shafts and the two second rotating shafts, and the two gears on the same side mesh with each other. Rotating sleeves are fixedly sleeved on the top ends of the two first rotating shafts and the two second rotating shafts. Multiple springs are fixedly connected to one side of the inner cavity of the rotating sleeves. An adjusting plug is fixedly connected to one end of the multiple second rotating shafts. Multiple positioning holes are opened on the outer surfaces of the adjusting plug and the rotating sleeves. A positioning plug is slidably inserted into the interior of the multiple positioning holes.

[0007] Preferably, the two rotating sleeves on the same side are located directly above the corresponding two gears, the mounting plate is L-shaped, and the four rotating sleeves are respectively rotatably disposed inside the L-shaped openings of the two mounting plates.

[0008] Preferably, the second connector is U-shaped, and the two synchronous pulleys and one synchronous belt are rotatably connected inside the second connector. The first connector is U-shaped, and the servo motor is fixed inside the first connector.

[0009] Preferably, one end of each of the four adjusting blocks is slidably inserted into the interior of the four rotating sleeves, and the other end of each of the four adjusting blocks is provided with an arc-shaped surface.

[0010] Preferably, connecting pieces are fixed to both sides of the first connector, and mounting holes are provided on the outer surfaces of both connecting pieces.

[0011] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0012] This invention uses a servo motor to activate four rotating sleeves, which drive four adjusting blocks to rotate or unfold towards the center of the second connector, thereby clamping the mold. Through the elasticity of multiple springs and the limiting connection of four positioning blocks, the four rotating sleeves can clamp the mold at different positions, preventing the clamping position of the device from affecting the mold's processing.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Please see Figure 1-4This utility model provides a clamping mechanism for milling machine molds, including a first connecting member 1. A second connecting member 2 is fixedly connected to the top of the first connecting member 1, and mounting plates 3 are fixedly connected to both sides of the top of the second connecting member 2. The tops of the two mounting plates 3 are rotatably connected to a first rotating shaft 4 and a second rotating shaft 5 via bearings. The bottom end of one of the first rotating shafts 4 and the bottom end of one of the second rotating shafts 5 penetrate through the interior of the second connecting member 2. A synchronous pulley 12 is fixedly sleeved at the bottom ends of both the first rotating shaft 4 and the second rotating shaft 5, and a synchronous belt is sleeved between the two synchronous pulleys 12 through tooth grooves. 13. A servo motor 14 is fixedly connected to the top of the inner cavity of the first connector 1, and the output shaft of the servo motor 14 is fixedly connected to the bottom end of the second rotating shaft 5 in the inner cavity of the second connector 2. Gears 6 are fixedly sleeved on the outer surfaces of the two first rotating shafts 4 and the two second rotating shafts 5, and the two gears 6 on the same side mesh with each other. Rotating sleeves 7 are fixedly sleeved on the top ends of the two first rotating shafts 4 and the two second rotating shafts 5. Multiple springs 15 are fixedly connected to one side of the inner cavity of the rotating sleeve 7. An adjusting plug 9 is fixedly connected to one end of the multiple second rotating shafts 5. Multiple positioning holes 16 are opened on the outer surfaces of the adjusting plug 9 and the rotating sleeve 7. A positioning block 8 is slidably inserted into the positioning hole 16. When the mold is placed at the top center of the second connecting piece 2, the servo motor 14 is activated, and the rotation of the two synchronous pulleys 12 and the synchronous belt 13 drives the first rotating shaft 4 and the second rotating shaft 5 to rotate. This, in turn, uses the four gears 6 to drive the four rotating sleeves 7 to rotate the four adjusting blocks 9 toward the mold. During the initial clamping, the four adjusting blocks 9 need to be inserted into the deepest possible depth of the four rotating sleeves 7, so that the four rotating sleeves 7 clamp the two clamping points on both sides of the mold closest to the center. The four positioning blocks 8 are then inserted into the connecting points between the four rotating sleeves 7 and the four adjusting blocks 9. The positioning holes 16 are used to clamp and position the mold. When the clamping position needs to be adjusted, the four positioning blocks 8 are pulled out. Then, the four rotating sleeves 7 are rotated outwards respectively. The elastic force of the multiple springs 15 is used to slowly pop the four adjusting blocks 9 outwards from the four rotating sleeves 7. When the four rotating sleeves 7 clamp the mold at different clamping positions on both sides and the multiple positioning holes 16 are connected, the four positioning blocks 8 are inserted to fix the position of the four adjusting blocks 9. This changes the clamping position of the device on the mold. Thus, while clamping the mold, the clamping position can also be adjusted, thereby avoiding the clamping of the device from affecting the milling machine's processing work and improving the applicability of the device.

[0021] To avoid the four gears 6 being exposed on the outside and causing certain safety hazards, two rotating sleeves 7 on the same side are located directly above the corresponding two gears 6. The mounting plate 3 is L-shaped, and the four rotating sleeves 7 are respectively rotatably set inside the L-shaped openings of the two mounting plates 3.

[0022] To facilitate the setting of two synchronous pulleys 12 and one synchronous belt 13, so that the four gears 6 drive the four adjusting blocks 9 to rotate or unfold synchronously toward the center of the second connector 2, the second connector 2 is shaped like a square, and the two synchronous pulleys 12 and one synchronous belt 13 are rotatably connected inside the second connector 2. The first connector 1 is shaped like a square, and the servo motor 14 is fixed inside the first connector 1.

[0023] To facilitate clamping the mold at different positions, one end of each of the four adjusting blocks 9 is slidably inserted into the interior of the four rotating sleeves 7, and the other end of each of the four adjusting blocks 9 is provided with an arc-shaped surface.

[0024] Furthermore, in order to fix the device and thus ensure the stability of the device during operation, connecting pieces 11 are fixedly connected to both sides of the first connecting piece 1, and mounting holes are opened on the outer surface of both connecting pieces 11.

[0025] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0026] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0027] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
