Abstract
Description
Technical Field
[0001] This application relates to the technical field of induction hardening, and in particular to an adjustable clamping device for induction hardening. Background Technology
[0002] For a long time, induction hardening has required the preparation of a full-circle toothed sample that is consistent with the specifications of the part, such as diameter, module, material and pretreatment state, to ensure that it can represent the part and simulate the part's processing state. After the sample is processed and inspected and qualified, the part is then induction hardened using the same parameters. This method has been used for a long time.
[0003] For small parts, the cost of a full-circle tooth profile sample is relatively low; however, for large gear rings and large-diameter gear shaft parts, more raw materials are required, and subsequent machining is also more inconvenient. The cost of a tooth profile sample that is consistent with the part specifications is very high. Utility Model Content
[0004] In order to save on raw material costs and subsequent machining costs, and to efficiently and accurately position and process induction hardened samples, this application provides an adjustable clamping device for induction hardening.
[0005] The adjustable clamping device for induction hardening provided in this application adopts the following technical solution:
[0006] An adjustable clamping device for induction hardening includes a central fixing block, a telescopic rod, and a clamping part;
[0007] One end of the telescopic rod is connected to the central fixing block, and the other end of the telescopic rod is connected to the clamping part. The telescopic rod is arranged on both sides of the central fixing block, and the axes of the telescopic rods on both sides are collinear.
[0008] The clamping part includes a mounting plate, a first clamping plate and a second clamping plate. The telescopic rod is fixedly connected to the mounting plate of the clamping part. The first clamping plate and the second clamping plate are slidably disposed on the mounting plate. The first clamping plate and the second clamping plate clamp a part sample block between them.
[0009] By adopting the above technical solution, before performing induction hardening on the actual part, the part sample block is clamped between the first and second clamping plates. The material and curvature of the part sample block are the same as those of the actual part. Then, the length of the telescopic rod is adjusted to accommodate toothed samples of different radii, matching the diameter of the actual part. The distance between the first and second clamping plates can be adjusted by sliding, thus facilitating the fixing of toothed samples of different heights, modules, and specifications. In practice, the central fixing block is installed on an existing turntable. By combining the existing turntable and reasonably extending it, adjustable induction hardening can be performed, meeting the induction hardening needs of toothed samples of various sizes and specifications. This reduces raw material and machining costs, improves production efficiency, and enables efficient and accurate positioning and processing of induction hardened part sample blocks.
[0010] The adjustable clamping device for induction hardening of this application is equivalent to the entire gear or gear shaft part during use, but saves most of the raw material cost of the core. It is flexible, lightweight, and adjustable in size, and is suitable for gears and gear shaft parts of various diameters. After the device is assembled, it can simulate the gear or gear shaft for induction hardening in a one-to-one manner, and assist in determining the processing parameters for subsequent induction hardening of the parts.
[0011] Optionally, the clamping part further includes a fixing screw, which passes through the end of the telescopic rod away from the central fixing block and is threadedly connected to the telescopic rod. A sliding groove is provided on the side of the mounting plate, and the first clamping plate and the second clamping plate pass through the sliding groove and are threadedly connected to both ends of the fixing screw, respectively.
[0012] By adopting the above technical solution, when the distance between the first clamping plate and the second clamping plate needs to be adjusted, the fixing screw is rotated and removed from the first clamping plate, the second clamping plate and the telescopic rod. Then, the first clamping plate and the second clamping plate slide in the slide groove, and the specified part sample block is clamped between the first clamping plate and the second clamping plate. This indicates that the distance between the first clamping plate and the second clamping plate is adjusted in place. Then, the fixing screw is screwed in and connected to the first clamping plate, the telescopic rod and the second clamping plate in sequence, so as to realize the adjustment and fixation of the distance between the first clamping plate and the second clamping plate.
[0013] Optionally, both the first clamping plate and the second clamping plate are provided with sliding sections. The part of the first clamping plate and the second clamping plate that passes through the slide groove is the sliding section. The width of the sliding section is less than the width of the rest of the first clamping plate and the second clamping plate, and the width of the sliding section is adapted to the width of the slide groove.
[0014] By adopting the above technical solution, the sliding section can be confined in the sliding groove, thereby improving the stability of the sliding of the first clamping plate and the second clamping plate.
[0015] Optionally, the fixing screw is threaded with two limiting nuts, which are located on both sides of the telescopic rod and between the first clamping plate and the second clamping plate, respectively, and abut against the first clamping plate and the second clamping plate.
[0016] By adopting the above technical solution, the limiting nut can limit the position of the first clamping plate and the second clamping plate, which helps to improve the stability of the position fixation of the first clamping plate and the second clamping plate.
[0017] Optionally, the clamping part further includes a fixing bolt and a fixing nut, wherein the fixing bolt passes through the first clamping plate and the second clamping plate to clamp one end of the part sample block and is threadedly connected to the fixing nut.
[0018] By adopting the above technical solution, the fixing bolt can fix one end of the part held by the first clamping plate and the second clamping plate, thereby improving the stability of the part sample block held by the first clamping plate and the second clamping plate and making the part sample block less likely to fall off.
[0019] Optionally, the telescopic rod includes an adjusting bolt, an adjusting nut, and a first rod body and a second rod body arranged vertically. A first adjusting groove is formed on the top surface of the first rod body, and a second adjusting groove is formed on the top surface of the second rod body. The adjusting bolt passes through both the first adjusting groove and the second adjusting groove and is locked by the adjusting nut.
[0020] By adopting the above technical solution, when the length of the telescopic rod needs to be adjusted, the adjusting nut is loosened to move the first rod and the second rod to the designated position, and then the adjusting nut is tightened again to fix it, so as to realize the extension and shortening of the telescopic rod. The structure is simple and the operation is convenient.
[0021] Optionally, the first rod is connected to the clamping part, the second rod is connected to the central fixing block, the end of the second rod away from the clamping part is the mounting part, the mounting part is arranged in a "T" shape, and the top surface of the central fixing block is provided with a T-shaped groove for the mounting part to be engaged.
[0022] By adopting the above technical solution, the installation part and the T-slot design facilitate the installation and positioning of the telescopic pole.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The adjustable clamping device for induction hardening of this application is equivalent to the entire gear or gear shaft part during use, but saves most of the raw material cost of the core. It is flexible, lightweight, easy to assemble and disassemble, and adjustable in size, and is suitable for gears and gear shaft parts of various diameters. After the device is assembled, it can simulate the gear or gear shaft for induction hardening in a one-to-one ratio, and assist in determining the processing parameters for subsequent induction hardening of the parts.
[0025] 2. After using the adjustable clamping device for induction hardening of this application, it is no longer necessary to prepare a whole circle of blank gears with the same diameter and height as the actual parts and suitable mechanical equipment for processing. It can quickly clamp toothed and non-toothed sample blocks of different diameters and perform rapid and accurate positioning, saving the time cost of finding a separate and temporary matching positioning fixture for each sample block, thus saving time and economic costs.
[0026] 3. Currently, there is no dedicated tooling for induction hardening of sample blocks. Instead, suitable methods are temporarily sought for induction hardening of sample blocks of various specifications. Due to the differences between parts and sample blocks, the efficiency of sample fixing and induction hardening is low and the production cycle is long. The adjustable clamping device for induction hardening proposed in this application can effectively improve efficiency. This device is suitable for induction hardening of toothed and non-toothed sample blocks and parts of various sizes, modules and specifications. It is adjustable in size, highly applicable, and simple in structure, which can significantly reduce the processing and clamping costs of induction hardened sample blocks. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] This application discloses an adjustable clamping device for induction hardening. (Refer to...) Figure 1-2The adjustable clamping device for induction hardening includes a central fixing block 1, a telescopic rod 2, and a clamping part 3. One end of the telescopic rod 2 is connected to the central fixing block 1, and the other end of the telescopic rod 2 is connected to the clamping part 3. The telescopic rod 2 is arranged on both sides of the central fixing block 1 in a radial direction, and the axes of the two telescopic rods 2 are collinear. The clamping part 3 includes a mounting plate 4, a first clamping plate 5, a second clamping plate 6, a fixing screw 7, a fixing bolt 8, and a fixing nut 9. The telescopic rod 2 is fixedly connected to the mounting plate 4 of the clamping part 3. The first clamping plate 5 and the second clamping plate 6 are slidably arranged on the mounting plate 4, and the first clamping plate 5 and the second clamping plate 6 clamp a part sample block 31.
[0034] Before induction hardening of the actual part, the part sample block 31 is clamped between the first clamping plate 5 and the second clamping plate 6. The material and curvature of the part sample block 31 are the same as those of the actual part. Then, the length of the telescopic rod 2 is adjusted to accommodate toothed samples of different radii, matching the diameter of the actual part. The distance between the first clamping plate 5 and the second clamping plate 6 can be adjusted by sliding, thus facilitating the fixing of toothed samples of different heights, modules, and specifications. In practice, the center fixing block 1 is installed on an existing turntable. By combining the existing turntable and reasonably extending it, adjustable induction hardening can be performed to meet the induction hardening needs of toothed samples of various sizes and specifications, reducing raw material and machining costs, and improving production efficiency. It can efficiently and accurately position and process the induction hardened part sample block 31.
[0035] The adjustable clamping device for induction hardening of this application is equivalent to the entire gear or gear shaft part during use, but saves most of the raw material cost of the core. It is flexible, lightweight, and adjustable in size, and is suitable for gears and gear shaft parts of various diameters. After the device is assembled, it can simulate the gear or gear shaft for induction hardening in a one-to-one manner, and assist in determining the processing parameters for subsequent induction hardening of the parts.
[0036] Reference Figure 1-3The telescopic rod 2 includes an adjusting bolt 21, an adjusting nut 22, and a first rod body 23 and a second rod body 24 arranged vertically. A first adjusting groove 231 is formed on the top surface of the first rod body 23, and a second adjusting groove 241 is formed on the top surface of the second rod body 24. The adjusting bolt 21 passes through both the first and second adjusting grooves 231 and 241 and is locked by the adjusting nut 22. When the length of the telescopic rod 2 needs to be adjusted, the adjusting nut 22 is loosened, allowing the first rod body 23 and the second rod body 24 to move relative to each other to the designated position. Then, the adjusting nut 22 is tightened again to fix the rod, thus achieving the extension and shortening of the telescopic rod 2. The structure is simple and the operation is convenient. The end face of the first rod body 23 is fixedly connected to the clamping part 3, and the second rod body 24 is connected to the central fixing block 1. The end of the second rod body 24 away from the clamping part 3 is the mounting part 242, which is T-shaped. The top surface of the central fixing block 1 has a T-groove 11 for the mounting part 242 to engage, facilitating the installation and positioning of the telescopic rod 2.
[0037] Reference Figure 2-4 The fixing screw 7 passes through the end of the telescopic rod 2 away from the central fixing block 1 and is threadedly connected to the telescopic rod 2. A sliding groove 41 is provided on the side of the mounting plate 4. The first clamping plate 5 and the second clamping plate 6 pass through the sliding groove 41 and are threadedly connected to both ends of the fixing screw 7, respectively. When the distance between the first clamping plate 5 and the second clamping plate 6 needs to be adjusted, the fixing screw 7 is rotated and removed from the first clamping plate 5, the second clamping plate 6 and the telescopic rod 2. Then, the first clamping plate 5 and the second clamping plate 6 are slid in the sliding groove 41, and the designated part sample block 31 is clamped between the first clamping plate 5 and the second clamping plate 6. This indicates that the distance between the first clamping plate 5 and the second clamping plate 6 is adjusted to the correct position. Then, the fixing screw 7 is screwed in and threadedly connected to the first clamping plate 5, the telescopic rod 2 and the second clamping plate 6 in sequence, thereby realizing the adjustment and fixation of the distance between the first clamping plate 5 and the second clamping plate 6.
[0038] Reference Figure 2-4 Both the first clamping plate 5 and the second clamping plate 6 are provided with sliding sections 51. The portion of the first clamping plate 5 and the second clamping plate 6 that passes through the sliding groove 41 is the sliding section 51. The width of the sliding section 51 is smaller than the width of the rest of the first clamping plate 5 and the second clamping plate 6, and the width of the sliding section 51 is adapted to the width of the sliding groove 41. The sliding section 51 can be confined within the sliding groove 41, improving the sliding stability of the first clamping plate 5 and the second clamping plate 6. The fixing screw 7 is threaded with two limiting nuts 71. The two limiting nuts 71 are located on both sides of the telescopic rod 2, and the two limiting nuts 71 are located between the first clamping plate 5 and the second clamping plate 6. The two limiting nuts 71 can limit the position of the first clamping plate 5 and the second clamping plate 6, which helps to improve the stability of the fixed position of the first clamping plate 5 and the second clamping plate 6.
[0039] Reference Figure 3 The fixing bolt 8 passes through the first clamping plate 5 and the second clamping plate 6 to clamp one end of the part sample block 31 and is threadedly connected to the fixing nut 9. The fixing bolt 8 can fix one end of the part clamped by the first clamping plate 5 and the second clamping plate 6, thereby improving the stability of the part sample block 31 clamped by the first clamping plate 5 and the second clamping plate 6 and making the part sample block 31 less likely to fall off.
[0040] The implementation principle of the adjustable clamping device for induction hardening in this application embodiment is as follows: First, the central fixing block 1 is installed on the existing turntable. Then, the mounting part 242 of the telescopic rod 2 is inserted into the T-slot 11 to install the telescopic rod 2 and the central fixing block 1. Next, the distance between the first clamping plate 5 and the second clamping plate 6 is adjusted, and the specified part sample block 31 is clamped between the first clamping plate 5 and the second clamping plate 6 and further fixed by the fixing bolt 8. The part sample block 31 is clamped to simulate the actual part. The adjustable device of this application is equivalent to the entire gear or gear shaft part in the process of use, but it saves most of the raw material cost of the core. It is flexible, lightweight, easy to assemble and disassemble, and adjustable in size. It can be used for gears and gear shaft parts of various diameters. Then, it can simulate the actual parts such as gears or gear shafts one-to-one for induction hardening processing, and assist in the determination of the subsequent induction hardening processing parameters of the actual parts.
[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
