Description

Technical Field

[0001] This utility model relates to the field of milling cutter processing technology, and in particular to a fixed fixture for milling cutter quenching processing. Background Technology

[0002] Quenching and tempering are two widely used heat treatment processes in production. These two processes are usually closely linked. Through quenching and tempering, the internal structure of steel is changed, so that the workpiece can obtain good mechanical properties and better exert the potential of material properties. Milling cutters are rotary cutting tools used for milling. In order to improve the hardness and strength of milling cutters, they are often quenched by heating them to a certain temperature.

[0003] Currently, existing quenching devices have certain defects when clamping milling cutters. Traditional devices generally clamp a single milling cutter and quench it sequentially, which makes it difficult to ensure that multiple milling cutters can be clamped quickly at the same time, and thus cannot meet the needs of large-scale production.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a fixed fixture for quenching milling cutters to solve the problems mentioned in the background art.

[0006] The purpose of this utility model can be achieved through the following technical solution: a fixed fixture for quenching milling cutters, including a mounting base, a fixed seat fixedly connected to the upper surface of the mounting base, a heating coil for quenching milling cutters fixedly mounted on the fixed seat, and a fixing mechanism provided on the mounting base;

[0007] The fixing mechanism includes a movable seat that is horizontally slidably connected to the upper surface of the mounting base. The movable seat is slidably connected to a plurality of spaced sleeves through which it is limited, which can satisfy the simultaneous quenching of multiple milling cutters. Two symmetrically arranged connecting bars are fixedly connected to the ends of the sleeves away from the fixed base. The two connecting bars are slidably connected to sliding bars. Clamping plates for holding milling cutters are fixedly connected to the opposite ends of the two sliding bars. Springs that abut against the clamping plates and connecting bars are sleeved on the sliding bars.

[0008] Preferably, a gear is fixedly connected to the outer wall of the sleeve, and a rack is horizontally slidably connected to the movable seat, with the rack meshing with the gear.

[0009] Preferably, the upper surface of the mounting base is provided with a sliding groove, the inner wall of the sliding groove is rotatably connected to a screw, the lower surface of the movable base is fixedly connected to a connecting block, and the screw passes through the connecting block and is screwed to the connecting block.

[0010] Preferably, the upper surface of the mounting base has two symmetrically arranged limiting grooves, and the two limiting grooves are connected to a slider that limits the sliding connection. The slider is fixedly connected to the lower surface of the movable base.

[0011] Preferably, a turntable is rotatably connected to the surface of the movable seat, an eccentric column is fixedly connected to the surface of the turntable, a push rod is movably connected to the eccentric column on the turntable, the surface of the push rod is provided with a movable groove that slides with the eccentric column, and the end of the push rod away from the turntable is fixedly connected to a rack.

[0012] Preferably, a limiting strip is fixedly connected to the surface of the movable seat, and the limiting strip passes through the rack and is slidably connected to the rack in the horizontal direction.

[0013] The beneficial effects of this utility model are:

[0014] (1) By setting multiple spaced sleeves, this utility model can simultaneously perform quenching operations on multiple milling cutters. Compared with the traditional method of quenching a single milling cutter in sequence, it greatly improves production efficiency, shortens the quenching time of a single batch of milling cutters, and meets the needs of large-scale production. Under the action of the spring, the two sliding bars are pushed to separate. When the end of the milling cutter is inserted into the sleeve and moves to the clamping plate, the spring can quickly fix the milling cutter after being released. Without complicated operation steps and additional tools, the installation and fixation of the milling cutter can be completed quickly, further improving the overall production efficiency.

[0015] (2) By moving the rack in the horizontal direction, the sleeve can be rotated, which in turn allows the milling cutter fixed in the sleeve to rotate. When the milling cutter moves into the heating coil, the rotation of the sleeve allows the milling cutter to be heated evenly. Even heating ensures that the microstructure of each part of the milling cutter is consistent, avoiding local overheating or underheating, thus ensuring the quality of quenching and improving the performance indicators such as hardness and wear resistance of the milling cutter.

[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 fixed fixture for quenching milling cutters, including a mounting base 1, a fixed base 4 fixedly connected to the upper surface of the mounting base 1, a heating coil 9 for quenching milling cutters fixedly mounted on the fixed base 4, and a fixing mechanism provided on the mounting base 1.

[0026] The fixing mechanism includes a movable seat 2 that is horizontally slidably connected to the upper surface of the mounting base 1. The movable seat 2 is slidably connected to a plurality of spaced sleeves 3 through which it is limited. The sleeves 3 and the heating coils 9 are horizontally spaced on the movable seat 2 and the fixed base 4, which can meet the requirement of quenching multiple milling cutters at the same time. Two symmetrically arranged connecting strips 17 are fixedly connected to the end of the sleeve 3 away from the fixed base 4. The two connecting strips 17 are slidably connected to a sliding strip 18 through which they are slidably connected. The opposite ends of the two sliding strips 18 are fixedly connected to a clamping piece 20 for holding the milling cutter. A spring 19 is sleeved on the sliding strip 18 that abuts against the clamping piece 20 and the connecting strip 17.

[0027] A gear 14 is fixedly connected to the outer wall of the sleeve 3, and a stop block is fixedly connected to the opposite end of the sliding bar 18 to prevent the sliding bar 18 from easily falling off the connecting bar 17. Under the action of the spring 19, the two sliding bars 18 are pushed to separate, the end of the milling cutter is inserted into the sleeve 3 and moved to the clamping plate 20. Releasing the spring 19 can quickly fix the milling cutter.

[0028] A rack 13 is horizontally slidably connected to the movable seat 2. The rack 13 meshes with the gear 14. When the rack 13 moves in the horizontal direction, it can cause the sleeve 3 to rotate, thereby causing the milling cutter fixed in the sleeve 3 to rotate. When the milling cutter moves into the heating coil 9, the rotation of the sleeve 3 can make the milling cutter heat evenly, which can ensure the quality of quenching.

[0029] The upper surface of the mounting base 1 has a groove 5, and a screw 6 is rotatably connected to the inner wall of the groove 5. The lower surface of the movable base 2 is connected to a connecting block 15. The movable base 2 and the connecting block 15 are connected by a tea block, which facilitates the immersion of the movable base 2 and the connecting block 15 in water or oil for cooling. The screw 6 passes through the connecting block 15 and is screwed to the connecting block 15. A motor is fixedly installed on the outer wall of the mounting base 1 to drive the screw 6 to rotate. The motor drives the screw 6 to rotate, thereby pushing the movable base 2 to move on the mounting base 1, which allows the milling cutter located in the sleeve 3 to move towards the heating coil 9 for quenching treatment.

[0030] Two symmetrically arranged limiting grooves 7 are provided on the upper surface of the mounting base 1. The two limiting grooves 7 pass through and are slidably connected to a slider 8. The slider 8 is fixedly connected to the lower surface of the movable base 2. Through the slider 8 and the limiting grooves 7, the movable base 2 can slide stably on the mounting base 1, ensuring the stability of the movable base 2 when it moves.

[0031] Example 2:

[0032] Please see Figures 1-5 As shown in this embodiment, a fixed fixture for quenching milling cutters has a movable base 2 with a turntable 10 rotatably connected to its surface. An eccentric column is fixedly connected to the surface of the turntable 10. A push rod 12 is movably connected to the eccentric column on the turntable 10. The surface of the push rod 12 has a movable groove 11 that is slidably connected to the eccentric column. The end of the push rod 12 away from the turntable 10 is fixedly connected to a rack 13. A second motor for driving the turntable 10 to rotate is fixedly installed on the movable base 2. When the turntable 10 rotates, the eccentric column slides in the movable groove 11 and reciprocates to push the push rod 12 and the rack 13 to move, thereby enabling the corresponding sleeve 3 to deflect, assisting in quenching and ensuring the quenching effect.

[0033] A limiting strip 16 is fixedly connected to the surface of the movable seat 2. The limiting strip 16 passes through the rack 13 and slides horizontally with the rack 13. The limiting strip 16 limits the horizontal movement of the rack 13 to ensure that the rack 13 moves stably in the horizontal direction.

[0034] Combining Embodiment 1 and Embodiment 2, by setting multiple spaced sleeves 3, multiple milling cutters can be quenched simultaneously. Compared with the traditional method of quenching a single milling cutter sequentially, this greatly improves production efficiency, shortens the quenching time of a single batch of milling cutters, and meets the needs of large-scale production. Under the action of spring 19, the two sliding bars 18 are pushed to separate. When the end of the milling cutter is inserted into the sleeve 3 and moves to the clamping plate 20, the spring 19 can quickly fix the milling cutter after being released. Without complicated operation steps and additional tools, the installation and fixation of the milling cutter can be completed quickly, further improving the overall production efficiency.

[0035] When the rack 13 moves horizontally, it causes the sleeve 3 to rotate, which in turn causes the end mill fixed inside the sleeve 3 to rotate. When the end mill moves into the heating coil 9, the rotation of the sleeve 3 allows the end mill to be heated evenly. Even heating ensures that the microstructure of each part of the end mill is transformed in a consistent manner, avoiding local overheating or underheating, thereby ensuring the quality of quenching and improving the hardness and wear resistance of the end mill.
