Abstract
Description
Technical Field
[0001] This utility model relates to the field of milling cutter coating fixture technology, and in particular to a fixture for spraying milling cutter coating. Background Technology
[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, the cutting teeth sequentially and intermittently remove 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. To avoid damage caused by collisions between the cutter and other devices or between cutters, a coating is usually added to the surface of the cutter to enhance its hardness and wear resistance.
[0003] Chinese patent CN208662303U discloses a fixture for spraying coatings on milling cutters. First, several quartz tubes are placed into slots on a base through through holes in a clamping plate. Then, an adjusting element is placed at the bottom of the quartz tubes. The adjusting element ensures that milling cutters of different lengths are exposed at the same height after being placed in the quartz tubes. The milling cutters are then uniformly sprayed. Although the staggered slots ensure that all milling cutters are sprayed, and the adjusting element allows for batch spraying of milling cutters of different lengths with consistent final spray height, improving spraying efficiency, in actual use, the spraying points are generally fixed, making it difficult to uniformly spray several milling cutters within the slots. This easily leads to uneven coating thickness on both sides of the milling cutters within the slots, making it difficult to guarantee the uniformity and accuracy of the spraying.
[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a fixture for spraying coatings on milling cutters to solve the problems mentioned in the background art.
[0006] The objective of this utility model can be achieved through the following technical solution: a milling cutter coating spraying fixture, comprising a base, a guide rod fixedly connected to the upper surface of the base, a connecting column fixedly connected to the center of the upper surface of the guide rod, a circular piece detachably connected to the connecting column, an installation groove formed on the lower surface of the base, and a positioning mechanism provided on the base.
[0007] The positioning mechanism includes two limiting rods that pass through the mounting slots. The two limiting rods are connected to positioning plates through and fixedly connected. The upper surface of the base and the circular plate is provided with an insertion slot for inserting a milling cutter. The top ends of the two limiting rods are fixedly connected to positioning plates that elastically abut against the surface of the base. The positioning plates are provided with positioning openings near the edge of the insertion slot that abut against the milling cutter.
[0008] Preferably, the upper surface of the base is fixedly connected to two symmetrically arranged guide rods, which pass through the circular piece and are slidably connected to the circular piece in the vertical direction.
[0009] Preferably, the insertion slot is an inverted conical hole, and the bottom edge of the positioning port is chamfered.
[0010] Preferably, a positioning piece is provided on the lower surface of the base, a baffle is fixedly connected to the bottom end of the limiting rod, and a spring is sleeved on the outer contour of the limiting rod, with the two ends of the spring abutting against the bottom of the positioning piece and the baffle, respectively.
[0011] Preferably, a connecting rod is fixedly connected to the lower surface of the connecting post, and the diameter of the connecting post is smaller than the diameter of the circular piece.
[0012] Preferably, a base plate is fixedly connected to the lower surface of the base to facilitate stable placement and support. The lower surface of the base plate has an opening one corresponding to the connecting rod, and the lower surface of the base plate has symmetrical openings two corresponding to the limiting rod to facilitate pressing the baffle plate in the opening two.
[0013] The beneficial effects of this utility model are:
[0014] (1) This utility model uses nuts to fix the position of the disc, thereby making the position of the disc adjustable to adapt to milling cutters of different lengths or specifications, improving the versatility and flexibility of the device, facilitating simultaneous spraying of multiple milling cutters, greatly improving spraying efficiency, and suitable for large-scale production scenarios. The base is placed on a rotating seat to ensure that the milling cutter can be sprayed evenly. The limiting rod passes through the mounting groove and is fixedly connected to the positioning port, and the positioning port on the positioning plate abuts against the milling cutter, ensuring the precise position of the milling cutter during the spraying process, which helps to ensure the uniformity and accuracy of the spraying.
[0015] (2) The positioning plate is kept in contact with the upper surface of the base and the positioning plate is pressed against the outer wall of the milling cutter under the action of the spring, thereby achieving elastic fixation of the milling cutter, enhancing the stability of the milling cutter during the spraying process, and effectively reducing the displacement or fall off of the milling cutter caused by vibration or external force. At the same time, the locking of the milling cutter can be easily released, thus facilitating the loading and unloading of the milling cutter. This design greatly improves the operating efficiency and reduces the time and effort required to replace the milling cutter. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1:
[0025] Please see Figures 1-5 As shown, this embodiment is a clamp for spraying coatings on milling cutters, including a base 1. A guide rod 2 is fixedly connected to the upper surface of the base 1. A connecting post 4 is fixedly connected to the center of the upper surface of the guide rod 2. A circular piece 3 is detachably connected to the connecting post 4. The outer wall of the connecting post 4 near the top is threaded. Nuts are fitted on the outer contours of the upper and lower surfaces of the guide rod 2. The position of the circular piece 3 is fixed by the nuts, thereby realizing the adjustable position of the circular piece 3, which can adapt to milling cutters of different lengths or specifications, improving the versatility and flexibility of the device. An installation groove 11 is provided on the lower surface of the base 1, and a positioning mechanism is provided on the base 1.
[0026] The positioning mechanism includes two limiting rods 12 that pass through the mounting slots 11. The two limiting rods 12 pass through and are fixedly connected to positioning ports 15. The upper surfaces of the base 1 and the circular plate 3 are provided with a ring array of insertion slots 7 for inserting milling cutters, which can facilitate the simultaneous spraying of multiple milling cutters, greatly improving the spraying efficiency and making it suitable for large-scale production scenarios. The base 1 is placed on a rotating seat, which can ensure that the milling cutters can be sprayed evenly. The tops of the two limiting rods 12 are fixedly connected to positioning plates 6 that elastically abut against the surface of the base 1. The positioning plates 6 have positioning ports 15 near the edge of the insertion slots 7 that abut against the milling cutters, ensuring the precise position of the milling cutters during the spraying process and helping to ensure the uniformity and accuracy of the spraying.
[0027] Two symmetrically arranged guide rods 2 are fixedly connected to the upper surface of the base 1. The two guide rods 2 pass through the circular piece 3 and slide vertically connected to the circular piece 3. The two guide rods 2 limit the vertical movement of the circular piece 3 to ensure that the insertion slot 1 7 on the circular piece 3 corresponds to the insertion slot 2 on the base 1.
[0028] The insertion slot 7 is an inverted conical hole, and the bottom edge of the positioning port 15 is chamfered. When the bottom end of the milling cutter is inserted into the insertion slot 7, the inverted conical hole supports the milling cutter and prevents it from falling directly through. The positioning port 15 abuts against the milling cutter and positions the milling cutter through friction and the insertion slot 7, preventing it from easily detaching from the insertion slot 7.
[0029] A positioning piece 6 is provided on the lower surface of the base 1. A baffle 10 is fixedly connected to the bottom end of the limiting rod 12. A spring 13 is sleeved on the outer contour of the limiting rod 12. The two ends of the spring 13 abut against the bottom of the positioning piece 6 and the baffle 10, respectively. By setting the spring 13, the positioning piece 6 can be made to fit against the upper surface of the base 1. Under the action of the spring 13, the positioning piece 6 abuts against the outer wall of the milling cutter to fix the milling cutter. Pushing the limiting rod 12 to separate the positioning piece 6 from the base 1 can lock the milling cutter.
[0030] A connecting rod 14 is fixedly connected to the lower surface of the connecting column 4. The diameter of the connecting column 4 is smaller than the diameter of the circular piece 3. The connecting column 4 is abutted against the bottom of the base 1 by bolts, thereby fixing the base 1 and the circular piece 3.
[0031] Example 2:
[0032] Please see Figures 1-5 As shown, in this embodiment, a milling cutter coating spraying fixture has a base plate 5 fixedly connected to the lower surface of the base 1 for stable placement and support. The lower surface of the base plate 5 has an opening 8 corresponding to the connecting rod 14, which facilitates the disassembly of the circular piece 3 and the base 1 through the opening 8. The lower surface of the base plate 5 has symmetrical openings 9 corresponding to the limiting rod 12, which facilitates pressing the baffle 10 inside the opening 9.
[0033] Combining Embodiments 1 and 2, by setting a positioning mechanism, multiple milling cutters can be sprayed simultaneously, greatly improving spraying efficiency and making it suitable for large-scale production scenarios. The position of the disc 3 is fixed by a nut, thereby making the position of the disc 3 adjustable and adaptable to milling cutters of different lengths or specifications. This improves the versatility and flexibility of the device, ensures the precise position of the milling cutter during the spraying process, and helps to ensure the uniformity and accuracy of the spraying. At the same time, the locking of the milling cutter can be easily released, which facilitates the loading and unloading of the milling cutter. This design greatly improves operating efficiency and reduces the time and effort required to replace the milling cutter.
