Description

Technical Field

[0001] This utility model belongs to the field of milling cutter manufacturing technology, specifically relating to a special fixture for milling cutter manufacturing and processing. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, each cutting tooth sequentially and intermittently removes the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. As a core tool in machining, the design, manufacturing, and application of milling cutters directly affect machining efficiency and accuracy. During production, milling cutters require precision grinding of the cutting edges using a grinding machine, and combined with electrical discharge machining (EDM) to process complex tooth profiles in cemented carbide materials. Therefore, the milling cutter needs to be clamped and fixed in place.

[0003] Current fixtures lack sufficient precision in holding and fixing milling cutters, often resulting in deviations between the clamping position and the intended position. This leads to errors in the cutting edge parameters of the milling cutter during machining, resulting in quality defects in the produced milling cutters. Furthermore, the machining process often generates a large amount of metal shavings, which, if not handled promptly, will accumulate on the fixture and require separate cleaning by personnel, which is quite troublesome.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a special fixture for milling cutter production and processing, which can solve the problems mentioned in the background art.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A special fixture for milling cutter production includes a fixed table. T-shaped grooves are arranged circumferentially on the upper side of the outer wall of the fixed table. A countersunk hole is formed in the middle of the fixed table. A sliding plate is slidably connected inside the T-shaped grooves. A fixing block is fixedly connected to the upper side of the outer wall of the sliding plate, penetrating the T-shaped grooves. A connecting rod is fixedly installed on the outer wall of the fixing block. Clamping blocks are fixedly installed on the outer walls of all the connecting rods near their ends.

[0008] The present invention is further configured such that: sliding rods are fixedly installed in a circumferential arrangement on the lower side of the outer wall of the fixed platform; sliding discs are slidably connected to the side walls of all the sliding rods; a connecting block is fixedly connected to the end of the sliding plate away from the clamping block; and a rotating block is rotatably connected to each of the connecting blocks and the sliding discs.

[0009] The present invention is further configured such that: a connecting plate is fixedly installed at the lower end of the outer wall of all the sliding rods, a screw is rotatably connected between the connecting plate and the lower side of the outer wall of the fixed platform, a threaded sleeve is fixedly installed in the middle of the sliding disk, and the threaded sleeve is threadedly connected to the screw.

[0010] The present invention is further configured such that: a motor frame is fixedly connected to the lower end of the outer wall of the connecting plate, a motor is fixedly installed inside the motor frame, and the output end of the motor passes through the connecting plate and is fixedly connected to the screw.

[0011] The present invention is further configured such that: the side wall of the fixed platform is circumferentially connected with connecting pipes communicating with the countersunk hole, all of the connecting pipes are simultaneously fixedly connected with annular pipes, and the side wall of the annular pipes is fixedly connected with an interface.

[0012] The present invention is further configured such that: mounting plates are fixedly installed circumferentially on the side wall of the fixed platform, and mounting blocks are fixedly installed on each mounting plate, and each mounting block is provided with threaded holes.

[0013] The technical effects achieved by this utility model are as follows:

[0014] 1. This utility model uses a starting motor to drive the screw to rotate. The rotation of the screw causes the sliding plate to slide downwards. Under the action of the rotating block, all the sliding plates will slide towards the axis of the fixed table at the same time, so that all the clamping blocks are close to the axis of the fixed table at the same time. This achieves clamping of the milling cutter to be processed and fixes the milling cutter to be processed at the axis of the fixed table, realizing precise clamping of the milling cutter and improving the accuracy of the milling cutter during processing.

[0015] 2. In use, the device is connected to an external negative pressure pipe through an interface, thereby generating negative pressure in the annular pipe and connecting pipe, and then generating negative pressure in the countersunk hole. This draws the metal debris generated during milling into the external collection device, thus simultaneously collecting and processing the metal debris generated during milling, preventing the metal debris from accumulating on the device, facilitating cleaning during use, and improving the convenience of using the device.

[0022] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-5 As shown, a special fixture for milling cutter production includes a fixed table 100. T-shaped grooves 110 are arranged circumferentially on the upper side of the outer wall of the fixed table 100. A countersunk hole 120 is formed in the middle of the fixed table 100. A sliding plate 200 is slidably connected inside the T-shaped grooves 110. A fixing block 210 that penetrates the T-shaped grooves 110 is fixedly connected to the upper side of the outer wall of the sliding plate 200. A connecting rod 220 is fixedly installed on the outer wall of the fixing block 210. Clamping blocks 230 are fixedly installed near the outer end of the outer wall of all the connecting rods 220. By sliding all the sliding plates 200 closer to each other, all the connecting rods 220 are moved closer to each other, and all the clamping blocks 230 are moved closer to each other, thus clamping the milling cutter.

[0024] Sliding rods 300 are fixedly installed in a circular arrangement on the lower outer wall of the fixed platform 100. All sliding rods 300 are slidably connected to sliding discs 310 on their side walls. A connecting block 320 is fixedly connected to the end of the sliding plate 200 away from the clamping block 230. Each connecting block 320 is rotatably connected to the sliding disc 310 by a rotating block 330. When the sliding disc 310 slides downward, under the action of the rotating block 330, all sliding plates 200 will be driven to slide simultaneously toward the axis of the fixed platform 100.

[0025] All sliding rods 300 have a connecting plate 400 fixedly installed at the lower end of their outer walls. A screw 410 is rotatably connected between the connecting plate 400 and the lower side of the outer wall of the fixed platform 100. A threaded sleeve 311 is fixedly installed in the middle of the sliding plate 310. The threaded sleeve 311 is threadedly connected to the screw 410. The rotation of the screw 410 drives the sliding plate 310 to slide up and down. A motor frame 500 is fixedly connected to the lower end of the outer wall of the connecting plate 400. A motor 510 is fixedly installed inside the motor frame 500. The output end of the motor 510 passes through the connecting plate 400 and is fixedly connected to the screw 410. The screw 410 is rotated by starting the motor 510.

[0026] Mounting plates 700 are fixedly mounted circumferentially on the side wall of the fixed platform 100. Mounting blocks 710 are fixedly mounted on each mounting plate 700. Each mounting block 710 is provided with a threaded hole 720. The device can be installed into the working environment through the threaded hole 720.

[0027] like Figure 1 and Figure 2 As shown, the sidewall of the fixed platform 100 is circumferentially connected with connecting pipes 600 that communicate with the countersunk hole 120. All connecting pipes 600 are also fixedly connected with annular pipes 610. The sidewall of the annular pipes 610 is fixedly connected with interfaces 620, which are used to connect with external negative pressure pipes, thereby generating negative pressure in the annular pipes 610 and connecting pipes 600, and then generating negative pressure in the countersunk hole 120 to collect metal chips generated during milling.

[0028] The working principle of this utility model is as follows: In use, the mounting block 710 and mounting plate 700 are first installed into the working environment through the threaded hole 720 to fix the device. Then, the starting motor 510 drives the screw 410 to rotate. The rotation of the screw 410 drives the sliding disk 310 to slide downward. When the sliding disk 310 slides downward, under the action of the rotating block 330, all the sliding plates 200 will slide simultaneously towards the axis of the fixed table 100. The simultaneous sliding of all the sliding plates 200 will drive all the connecting rods 220 to move closer simultaneously, so that all the clamping blocks 230 will move closer to the axis of the fixed table 100, thus allowing the milling cutter to be processed. The device clamps and fixes the milling cutter to be processed at the axis of the fixed table. At the same time, the device is connected to the external negative pressure pipe through the interface 620, thereby generating negative pressure in the annular pipe 610 and the connecting pipe 600, and then generating negative pressure in the countersunk hole 120 to collect the metal chips generated during the milling process, preventing the metal chips from accumulating on the device. After processing is completed, the motor 510 can be restarted to drive the screw 410 to rotate, causing the sliding plate 310 to slide upward, allowing all the sliding plates 200 to slide simultaneously and drive all the connecting rods 220 to move away at the same time. At this time, all the clamping blocks 230 are disengaged from the milling cutter, and the personnel can remove the milling cutter.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
