Description

Technical Field

[0001] This utility model belongs to the field of axle keyway milling technology, specifically relating to an axle keyway milling device. Background Technology

[0002] A keyway milling device for axles is a type of equipment used to machine keyways on axles. It typically consists of a frame, a milling cutter drive mechanism, a clamping mechanism, and a drive control mechanism. In practical applications, the clamping mechanism clamps the axle to be machined, and the drive control mechanism drives the milling cutter to rotate, thereby performing keyway milling on the axle.

[0003] Because axles have a large length, and the keyway machining location is usually at both ends of the axle, most existing axle keyway milling devices only clamp and fix the axle on one side of the keyway machining location during the machining process. However, due to the large length and weight of the axle, clamping and fixing only one side of the axle has poor stability, making the axle prone to shaking during keyway milling. This results in poor machining stability and accuracy of the axle keyway milling device.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a device for milling keyways on axles.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a device for milling keyways on axles, which can improve the stability and machining accuracy of keyway milling on axles.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides a keyway milling device for axles, comprising: a frame, a worktable, a double-sided clamping assembly, and an auxiliary support assembly.

[0008] A worktable is slidably mounted on the frame.

[0009] The double-sided clamping assembly is fixedly mounted on the top of the worktable.

[0014] In one or more embodiments of this utility model, an anti-slip pad is fixedly attached to the underside of the clamping arc plate. This ensures the anti-slip performance of the clamping arc plate and also reduces damage to the outer surface of the axle during clamping. A drive handle is fixedly connected to the end of the drive threaded rod away from the clamping arc plate. By controlling the rotation of the drive handle, the drive threaded rod is rotated, thereby facilitating the synchronous lifting and lowering movement of the clamping arc plate under the action of the internal and external threads.

[0015] In one or more embodiments of this utility model, a pair of receiving grooves are provided on the adjacent sides of the pair of base supports. The receiving grooves are used to receive and guide the limiting guide rods. Each pair of receiving grooves contains a limiting guide rod.

[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] like Figures 1 to 4 As shown, a keyway milling device for axles in one embodiment of the present invention includes: a frame 1, a worktable 101, a double-sided clamping assembly 2, and an auxiliary support assembly 3.

[0030] like Figure 1 As shown, a worktable 101 is slidably mounted on the frame 1. The worktable 101 assembles and fixes the double-sided clamping assembly 2.

[0031] like Figures 2 to 4 As shown, the double-sided clamping assembly 2 is fixedly mounted above the worktable 101. The double-sided clamping assembly 2 includes a pair of fixed supports 201, both of which are fixedly mounted above the worktable 101. The base support 202 is supported and fixed by the pair of fixed supports 201.

[0032] like Figure 4 As shown, both sides of the bottom of a pair of fixed supports 201 are integrally formed with fixed ear plates 206, and the fixed ear plates 206 are fixedly connected to the worktable 101 by assembly bolts 207. The fixed ear plates 206 are assembled and fixed by the assembly bolts 207, so that the fixed supports 201 can be fixedly assembled on the top of the worktable 101.

[0033] like Figures 2 to 3 As shown, a base support 202 is fixedly connected above each of the pair of fixed supports 201. The base supports 202 can support and limit the bottom of the axle to be processed.

[0034] like Figures 3 to 4 As shown, a top support 203 is fixedly mounted above each pair of base supports 202. The top support 203 supports and limits the top of the axle to be processed. At the same time, the top support 203 performs assembly limiting and sliding guidance control for the drive threaded rod 204.

[0035] It is worth noting that different diameter base supports 202, top supports 203, and auxiliary support components 303 can be selected according to different diameter axles.

[0036] like Figure 3 As shown, both sides of the pair of base supports 202 are integrally formed with base support fixing plates 208, and both sides of the pair of top supports 203 close to the base supports 202 are integrally formed with top support fixing plates 209. Fixing through holes are provided on both the base support fixing plates 208 and the top support fixing plates 209. The base support fixing plates 208 and the top support fixing plates 209 are assembled and fixed through these fixing through holes, thereby facilitating the connection and fixation of the base supports 202 and the top supports 203.

[0037] like Figure 3 As shown, multiple sets of connecting bolts 210 are fixedly connected between the bottom support fixing plate 208 and the top support fixing plate 209. The bottom support fixing plate 208 and the top support fixing plate 209 are connected and fixed by the multiple sets of connecting bolts 210.

[0038] like Figure 4 As shown, anti-slip pads 211 are fixedly attached to the top of each pair of base supports 202. The anti-slip pads 211 improve the anti-slip performance of the base supports 202. Simultaneously, the anti-slip pads 211 allow the base supports 202 to provide flexible support to the outer surface of the axle, reducing friction between the base supports 202 and the outer surface of the axle, thus minimizing damage to the axle's outer surface.

[0039] like Figure 3 As shown, the top support 203 is internally threaded with a drive threaded rod 204. The drive threaded rod 204 provides support, limits, and movement control for the clamping arc plate 205. One end of the drive threaded rod 204, located inside the bottom support 202, is rotatably connected to the clamping arc plate 205. By controlling the movement of the clamping arc plate 205 in conjunction with the fixed support 201, the axle to be processed can be clamped and fixed.

[0040] like Figure 3As shown, an anti-slip pad 212 is fixedly attached to the lower part of the clamping arc plate 205. This ensures the anti-slip performance of the clamping arc plate 205 and also reduces the damage to the outer surface of the axle caused by the clamping arc plate 205 during the clamping and fixing process.

[0041] like Figure 3 As shown, a drive handle 213 is fixedly connected to the end of the drive threaded rod 204 away from the clamping arc plate 205. By controlling the rotation of the drive handle 213, the drive threaded rod 204 is rotated, thereby facilitating the synchronous lifting and lowering movement of the clamping arc plate 205 under the action of the internal and external threads.

[0042] Specifically, a pair of storage grooves are provided on the adjacent sides of the pair of base supports 202. The storage grooves are used to store and guide the limiting guide rod 214.

[0043] like Figure 4 As shown, a pair of storage grooves each have a slidably fitted limit guide rod 214. The pair of limit guide rods 214 connect and limit the pair of base supports 202, ensuring consistent support and limiting of the axle by the pair of base supports 202. Furthermore, by adjusting the length of the pair of limit guide rods 214 extending out of the storage grooves, the pair of base supports 202 can adapt to the requirements of machining keyways of different lengths.

[0044] like Figure 4 As shown, the auxiliary support assembly 3 is fixedly mounted on one side of the frame 1. The auxiliary support assembly 3 includes a retractable base rod 301, which is fixedly mounted on one side of the frame 1. The retractable base rod 301 serves to support, limit, and guide the sliding movement of the retractable support rod 302.

[0045] like Figures 3 to 4 As shown, a support base plate 304 is fixedly connected to the bottom of the retractable base rod 301. The retractable base rod 301 is supported and fixed by the support base plate 304. Several fastening bolts 305 are fixedly connected between the support base plate 304 and the frame 1. The support base plate 304 and the frame 1 are connected and fixed by several fastening bolts 305.

[0046] like Figures 3 to 4 As shown, a reinforcing rib 306 is fixedly connected between the supporting base plate 304 and the retractable base rod 301, and the reinforcing rib 306 is fixedly connected to the side wall of the retractable base rod 301. The reinforcing rib 306 provides an auxiliary connection between the supporting base plate 304 and the retractable base rod 301, thereby improving the strength of the assembly connection of the retractable base rod 301.

[0047] like Figure 2As shown, a retractable support rod 302 is slidably mounted inside the retractable base rod 301. The retractable support rod 302 supports and fixes the auxiliary support member 303. Simultaneously, the height of the auxiliary support member 303 can be adjusted by raising and lowering the retractable support rod 302. The auxiliary support member 303 is fixedly connected to one end of the retractable support rod 302 outside the retractable base rod 301. The auxiliary support member 303 provides auxiliary support for the long axle, reducing the likelihood of the axle swaying or shifting due to its own weight.

[0048] like Figure 2 As shown, a fixing screw 307 is threaded onto one side of the retractable base rod 301. One end of the fixing screw 307, located inside the retractable base rod 301, contacts the outer surface of the retractable support rod 302. The retractable support rod 302 is locked and positioned by pressing the outer surface of the retractable support rod 302 with the fixing screw 307.

[0049] like Figure 4 As shown, an auxiliary anti-slip pad 308 is fixedly attached to the upper side of the auxiliary support 303, and the auxiliary support 303 is at the same horizontal height as the pair of retractable support rods 302. This ensures the stability of the auxiliary support 303 in supporting the axle.

[0050] It is worth noting that the anti-slip base pad 211, the anti-detachment clamping pad 212, and the auxiliary anti-slip pad 308 can all be made of rubber, which has the advantages of good anti-slip performance and low cost of use.

[0051] In practical use, the spacing between a pair of fixed supports 201 can be adjusted by controlling the retraction or expansion of the limit guide rod 214 according to the size of the keyway to be processed. When milling the axle, the axle to be processed is inserted between a pair of bottom supports 202 and top supports 203. Subsequently, the drive threaded rod 204 can be rotated by rotating the drive handle 213. The clamping arc plate 205 can move up and down synchronously with the lifting and lowering movement of the drive threaded rod 204. The clamping arc plate 205 and the bottom support 202 can clamp and fix the two sides of the keyway to be processed on the axle.

[0052] In addition, the axle to be machined can be supported and limited by the cooperation of the retractable base rod 301, the retractable support rod 302, the auxiliary support component 303 and the support base plate 304. By supporting the axle to be machined at multiple points, the stability and accuracy of the subsequent milling of the axle are ensured.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
