Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of screw heat treatment, and particularly relates to a heat treatment device for ball screw machining. BACKGROUND

[0002] The ball screw is the most commonly used transmission element in tooling machinery and precision machinery, and its main function is to convert rotary motion into linear motion or convert torque into axial repeated force, and it has the characteristics of high precision, reversibility and high efficiency. Since it has very small frictional resistance, the ball screw is widely used in various industrial equipment and precision instruments. In the process of ball screw machining, heat treatment operation is required. The current ball screw heat treatment device usually rotates the screw while passing through the electromagnetic heating coil, the electromagnetic heating coil quickly heats the screw, and then the cooling liquid is sprayed on the surface of the screw to cool it.

[0003] In the above-mentioned screw heat treatment step, the diameter of the screw determines the speed of the screw passing through the coil and the speed of the screw rotating. For a smaller diameter screw, the speed of passing through the heating coil is faster, and for a larger diameter screw, in order to ensure that the shaft part is fully heated, the speed of passing through the heating coil is relatively slow. The specification size of the heat treatment equipment in the prior art is mostly fixed. When heat treatment is performed on screws of different diameters, the corresponding type of heat treatment device needs to be selected according to the diameter of the screw. Therefore, the same type of heat treatment device in the prior art can only perform heat treatment operation on a single size of screw, and has low flexibility and narrow application range, which cannot meet more actual use requirements.

[0027] In the following description, a lot of specific details are set forth in order to give a thorough understanding of the present application, but the present application can also be implemented in other ways different from the description, and those skilled in the art can make similar generalizations without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0028] REFERENCE Figures 1-9For the embodiment of the present application, including a heat treatment device for ball screw machining, comprising a base 1 and a conveying unit 2, the conveying unit 2 comprises a fixed part 21 located on the base 1, and the top end of the fixed part 21 is provided with a limiting seat 215, an adjusting part 22 is rotatably connected to the fixed part 21, and the fixed part 21 and the adjusting part 22 are concentric and coaxial, a support part 23 is inserted into the fixed part 21, a planet gear 24 is correspondingly provided on the side of each group of support parts 23, and the planet gear 24 is respectively engaged with the inner wall of the adjusting part 22 and the side of the support part 23, a driven part 25 is vertically inserted into the limiting seat 215, and a driving part 26 is located on one side of the top end of the driven part 25; With reference to Figure 5 , the adjusting part 22 comprises a gear ring 221 rotatably connected to the fixed part 21, and an internal gear 223 is opened on the inner wall of the gear ring 221 and engaged with the planet gear 24, the gear ring 221 can drive the planet gear 24 to rotate synchronously through the internal gear 223 when rotating; With reference to Figure 6 , the support part 23 comprises three groups of extension rods 231 equally divided and inserted into the fixed part 21, and the inner end of each group of extension rods 231 is transversely inserted with a group of feeding drums 6, an engagement rack 232 is opened on the side of the extension rod 231, and the engagement rack 232 is engaged with the planet gear 24, and a limiting sleeve 233 is provided on the side of a group of extension rods 231 in the vertical direction, the planet gear 24 will drive the extension rod 231 to move through the engagement with the engagement rack 232 when rotating, three groups of extension rods 231 move synchronously, and the action of gathering inward or expanding outward can be realized, so as to realize the purpose of adjusting the corresponding range of embrace according to the actual diameter of the screw rod; With reference to Figure 3The driven component 25 includes an extension shaft 251 inserted into the limiting seat 215, and the extension shaft 251 passes through the limiting sleeve 233 downward, a bevel gear one 252 arranged at the end of the extension shaft 251, a gear disc 253 arranged at the top of the bevel gear one 252, and a bevel gear two 254 arranged at the side of the bevel gear one 252, and the bevel gear two 254 is fixedly connected with one end of the feeding drum 6, and the bevel gear one 252 and the bevel gear two 254 are engaged and driven. The driven component 25 is limited by the limiting seat 215 and can move vertically on the limiting seat 215, and the end of the driven component 25 is limited by the limiting sleeve 233 and is always connected with the supporting component 23, so as to move with the supporting component 23. The gear disc 253 is engaged with the driving component 26 and can drive the driven component 25 to rotate as a whole. The rotating driven component 25 drives the feeding drum 6 connected with the bevel gear two 254 to rotate through the engagement of the bevel gear one 252 and the bevel gear two 254, and the rotating feeding drum 6 drives the lead screw to rotate and feed. With reference to Figure 3 The driving component 26 includes a circular truncated cone gear 262, and the circular truncated cone gear 262 is engaged and driven with the gear disc 253, and the inclined edge of the circular truncated cone gear 262 is perpendicular to the gear disc 253. The inclined edge perpendicular to the gear disc 253 ensures that the gear disc 253 is always engaged and connected with the circular truncated cone gear 262 when the gear disc 253 moves vertically. The circular truncated cone gear 262 is thin at the bottom and thick at the top, so the diameter of each part of the circular truncated cone gear 262 decreases from bottom to top. When the gear disc 253 is of a constant size, the rotation amplitude of the gear disc 253 is different when the gear disc 253 is engaged with different parts of the circular truncated cone gear 262. The rotation speed of the gear disc 253 when the gear disc 253 is engaged with the part of the circular truncated cone gear 262 with a larger diameter is obviously greater than the rotation speed when the gear disc 253 is engaged with the part of the circular truncated cone gear 262 with a smaller diameter.

[0029] With reference to Figure 4 The fixed component 21 includes a fixed ring 211 in a circular ring structure, a limiting frame 212 arranged at the side of the fixed ring 211, a gap slot 213 arranged between the fixed ring 211 and the limiting frame 212, the adjusting component 22 installed in the gap slot 213, and a fixed plate 217 fixedly connected below the fixed ring 211 and the limiting frame 212, and the fixed plate 217 is fixedly connected to the base 1. The fixed ring 211 and the limiting frame 212 are fixedly connected to the base 1 through the fixed plate 217, so that the whole working process of the fixed component 21 is to be fixedly connected to the base 1 and kept stationary.

[0030] Further, with reference to Figure 4The fixing component 21 further comprises three sets of slots 214 equidistantly arranged on the fixing ring 211, and three sets of extension rods 231 are correspondingly inserted into the three sets of slots 214, a fixing frame 216 is arranged on the side surface of each set of slots 214, and the planetary gear 24 is rotatably arranged on the fixing frame 216. The three sets of slots 214 limit the moving direction of the three sets of extension rods 231, so that the three sets of extension rods 231 can only move towards or away from the axis of the fixing component 21, and the three sets of fixing frames 216 are used for mounting the planetary gear 24. The planetary gear 24 can freely rotate on the fixing component 21 through the fixing frame 216, and the position of the planetary gear 24 will not change during rotation.

[0031] Further, referring to Figure 5 The adjusting component 22 further comprises a limiting ring 222 arranged on the side surface of the gear ring 221, and the adjusting component 22 is rotatably connected to the fixing component 21 through the limiting ring 222, and an external gear 224 is arranged on the outer wall of the gear ring 221. The limiting ring 222 is limitedly connected to the fixing component 21 through cooperation with the limiting frame 212, so that the adjusting component 22 can rotate in the circumferential direction on the fixing component 21, and the position of the adjusting component 22 will not change in the vertical direction or the horizontal direction during rotation.

[0032] Further, referring to Figure 8 The adjusting component 22 is horizontally arranged below the adjusting component 27, the adjusting component 27 comprises a driving rod 271 arranged below the gear ring 221, one end of the driving rod 271 is rotatably connected to the base 1, and a helical rack 272 is spirally wound on the driving rod 271. The helical rack 272 is in meshing transmission with the external gear 224, and the outer end of the driving rod 271 can be connected to a driving source according to actual use requirements, such as a motor, a rotary air cylinder or a hand wheel disc. When the driving rod 271 drives the helical rack 272 to rotate, the helical rack 272 will drive the adjusting component 22 to rotate through the meshing of its structure and the external gear 224, so that the rotating adjusting component 22 drives the supporting component 23 to adjust the range of the rotating adjusting component 22.

[0033] Further, referring to Figure 3 The driving component 26 further comprises a motor 261 fixedly connected to the base 1, and a circular truncated cone gear 262 is connected to the top end of the motor 261. The motor 261 provides power for the rotation of the motor 261, and then drives the feeding drum 6 corresponding to the driven component 25 to rotate through the meshing of the circular truncated cone gear 262 and the gear disc 253.

[0034] Further, in the process of screw conveying, the three groups of feeding drums 6 keep close contact with the outer wall of the screw, and the screw itself has threads. When one of the groups of feeding drums 6 rotates, the friction between the feeding drum 6 and the screw will become the operation of pushing the screw to feed and convey under the guidance of the threads on the outer wall of the screw. In this process, the screw is synchronously self-rotating. The rotation speed of the feeding drum 6 will directly affect the self-rotation speed and the conveying and feeding speed of the screw. The faster the feeding drum 6 rotates, the faster the self-rotation speed and the conveying and feeding speed of the screw will be.

[0035] Further, referring to Figure 1 , the base 1 includes a support unit 3 arranged on the side of the conveying unit 2, a heating coil 4 arranged on the side of the conveying unit 2, and a quenching component 5 arranged on the side of the heating coil 4. The heating coil 4 and the quenching component 5 are respectively common heating structures and cooling structures in the prior art.

[0036] Further, referring to Figure 1 , the conveying unit 2, the support unit 3, the heating coil 4, and the quenching component 5 are coaxial and arranged in sequence from left to right. The coaxial arrangement of the four can ensure that the screw to be heat-treated is at the same horizontal height.

[0037] Referring to the drawings, the support unit 3 includes a support frame 31 parallel to the conveying unit 2 and three groups of auxiliary rods 32 equally arranged around the support frame 31. The support frame 31 is used to support the other end of the feeding drum 6 in cooperation with the conveying unit 2 to ensure that the screw is at the same horizontal height during conveying.

[0038] Further, referring to Figure 1 , the three groups of auxiliary rods 32 on the support unit 3 correspond to the three groups of extension rods 231 on the support component 23, and the two ends of the feeding drum 6 are respectively connected to the extension rods 231 and the auxiliary rods 32. The auxiliary rods 32 and the extension rods 231 are connected integrally through the feeding drum 6. Therefore, when the extension rods 231 move, the auxiliary rods 32 will be synchronously moved through the feeding drum 6. The mutual cooperation of the two also plays a certain auxiliary supporting role for the feeding drum 6.

[0039] In summary, when the screws of different diameters are subjected to heat treatment, the screws are conveyed into the device through the previous step. According to the actual size of the screw, the adjusting component 22 is driven to rotate by the adjusting component 27. The three groups of planetary gears 24 are driven to rotate by the inner gear 223 on the inside of the adjusting component 22. The rotating planetary gears 24 push the corresponding support components 23 to move through the meshing with the rack 232. At this time, the three groups of support components 23 move synchronously. In combination with Figure 8, if the screw at this time needs to be heat treated is small diameter screw 7, then drive three groups of support components 23 to shrink inward action, three groups of shrink action support components 23 will bring their corresponding feed cylinder 6 from three directions evenly abut on the outer wall of small diameter screw 7, in the process of three groups of support components 23 shrink, the support components 23 in the vertical direction will synchronously drive the driven component 25 to move downward in the vertical direction, the downward moving driven component 25 will make the gear disc 253 at the top thereof move from the smaller diameter part of the circular cone gear 262 to the larger diameter part, at this time the driving component 26 drives the driven component 25 to rotate through the meshing of the circular cone gear 262 and the gear disc 253, since the gear disc 253 is meshed with the larger diameter part of the circular cone gear 262 at this time, the rotation speed of the driven component 25 is faster at this time, the driven component 25 with faster rotation speed will push the feed cylinder 6 to rotate at a faster speed through the meshing of bevel gear one 252 and bevel gear two 254, the feed cylinder 6 rotating at a faster speed will also drive the small diameter screw 7 to rotate at a faster speed and to feed at a faster speed, the conveying unit 2 at this time can realize the rotation feeding operation of the small diameter screw 7; In combination Figure 9 , on the contrary, when the screw to be heat treated is large diameter screw 8, the support components 23 will expand outward according to the diameter of the screw, so that the feed cylinder 6 can fully embrace the outer wall of the large diameter screw 8, at this time the outward expanding support components 23 will drive the driven component 25 to move upward, the upward moving driven component 25 will make the gear disc 253 mesh with the smaller diameter part of the circular cone gear 262, at this time the driving component 26 drives the driven component 25 to rotate through the meshing of the circular cone gear 262 and the gear disc 253, since the gear disc 253 is meshed with the smaller diameter part of the circular cone gear 262 at this time, the rotation speed of the driven component 25 is slower at this time, the driven component 25 with slower rotation speed will push the feed cylinder 6 to rotate at a slower speed through the meshing of bevel gear one 252 and bevel gear two 254, the feed cylinder 6 rotating at a slower speed will also drive the large diameter screw 8 to rotate at a slower speed and to feed at a slower speed, the conveying unit 2 at this time can realize the rotation feeding operation of the large diameter screw 8 at a slower speed, ensuring that the large diameter screw 8 with larger diameter can be fully heated; After adjusting the rotation and feeding speed of the screw according to the diameter of the screw, the conveying unit 2 will convey the screw downward to the heating coil 4 and the quenching component 5 to perform heating, quenching and other operations in sequence; The speed of driving the lead screw to rotate and feeding in the above process is proportional to the actual diameter of the lead screw, the smaller the diameter of the lead screw is, the larger the part of the gear disc 253 meshes with the circular cone gear 262 is, and then the rotating speed and the feeding speed of the lead screw to be fed are faster, on the contrary, the larger the diameter of the lead screw is, the smaller the part of the gear disc 253 meshes with the circular cone gear 262 is, and then the rotating speed and the feeding speed of the lead screw to be fed are slower, and thus it can be known that the present application can adaptively adjust the speed of driving the lead screw to rotate and feeding according to the diameter of the lead screw, so that the present device can realize the function of heat treatment operation on the lead screw with different diameters, and can ensure effective heat treatment operation on the lead screw with different diameters, greatly enhancing the use flexibility of the heat treatment device and meeting more use requirements.

[0040] It should be noted that the above examples are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
