Description

Technical Field

[0001] This application relates to the technical field of electric vehicle parts processing, and in particular to a special turning device for electric vehicle motor side covers. Background Technology

[0002] Electric vehicle parts processing is a crucial part of modern manufacturing. As a key component of the electric vehicle motor, the quality of the motor side cover's processing directly affects the motor's performance and lifespan. Specialized turning equipment is commonly used to process and manufacture motor side covers.

[0003] Currently, in the machining process of electric vehicle motor side covers, traditional turning equipment mostly uses two clamping methods: three-jaw chuck hard clamping or simple end face clamping. Due to the complexity of the electric vehicle motor side cover workpiece structure, and the fact that some specifications of the side cover have thin walls and poor rigidity, the clamping force of traditional clamping mechanisms cannot achieve uniform distribution, and is very likely to be concentrated on a local area of ​​the workpiece, exceeding the reasonable stress range that the workpiece material itself can withstand.

[0004] Under the localized concentration of clamping force, the workpiece will undergo varying degrees of deformation, specifically elastic deformation or plastic deformation. Elastic deformation often occurs in edge cover workpieces with relatively uniform wall thickness and good material toughness, while plastic deformation is common in thinner wall and structurally weaker parts of the workpiece. This deformation is temporarily fixed during the turning process. When the machining operation is completed and the fixture is released, the clamping stress on the workpiece will gradually be released, resulting in springback. Workpiece springback will directly lead to a serious decrease in machining accuracy, causing problems such as elliptical inner holes, warped end faces, and out-of-tolerance dimensional tolerances at the stop.

[0027] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0028] The following describes a special turning device for electric vehicle motor side cover according to an embodiment of this application, with reference to the accompanying drawings.

[0029] like Figure 1-6 As shown in the figure, a special turning device for electric vehicle motor side cover according to an embodiment of this application may include: a machine body 11, a mounting column 12, a clamping block 13, a cutting assembly 14 and a fixing mechanism 3.

[0030] The fixing mechanism 3 is installed on the mounting column 12, one end of which is connected to the inner wall of the machine body 11. Multiple clamping blocks 13 are provided, and the multiple clamping blocks 13 are respectively installed on the mounting column 12. The cutting assembly 14 is installed inside the machine body 11. The fixing mechanism 3 includes a connecting column 31, a rotating block 33, a contact block 34, a fixing column 35, and a fixing block 36.

[0031] The mounting post 12 has a fixing hole 121 at the other end, a connecting post 31 is set in the fixing hole 121, a connecting groove 32 is set inside the connecting post 31, a rotating block 33 is set in the connecting groove 32, a plurality of approach blocks 34 are provided, and the plurality of approach blocks 34 are respectively set on the outer wall of the rotating block 33, the top surface of the plurality of approach blocks 34 is inclined, a plurality of fixing posts 35 are provided, and one end of the plurality of fixing posts 35 abuts against the corresponding approach block 34, and the other end of the fixing posts 35 passes through the connecting groove 32 and is connected to the corresponding fixing block 36.

[0032] It should be noted that the top of the approach block 34 described in this embodiment is an inclined surface. Its main function is to push the fixed column 35 along the direction of the inclined surface during the rotation of the approach block 34, thereby achieving outward movement.

[0033] Specifically, before machining the motor side cover using the lathe body 1, the operators first place the motor side cover on the mounting post 12 and use multiple clamping blocks 13 to initially fix the motor side cover from the outside. Next, the operators use the control component 4 to push the connecting post 31 out of the fixing hole 121 and control the rotating block 33 to rotate. At this time, the approach block 34 rotates along with the rotating block 33, moving the fixing post 35 outwards. This allows the fixing block 36 to press against the inner wall of the motor side cover, and together with the clamping blocks 13, fix the outer wall of the motor side cover, preventing deformation of the side cover caused by unilateral fixing.

[0034] like Figure 1 As shown, in one embodiment of this application, the cutting assembly 14 includes a slide rail 141, a slide block 142, a mounting base 143, and a cutting blade 144.

[0035] The slide rail 141 is installed inside the machine body 11, the slide block 142 is slidably connected to the slide rail 141, the mounting base 143 is slidably connected to the slide rail 141 through the slide block 142, and the cutting blade 144 is installed on the outer wall of the mounting base 143.

[0036] The cutting assembly 14 also includes a cooling assembly 7.

[0037] The cooling component 7 is mounted on the mounting base 143.

[0038] The cooling component 7 includes a diversion pipe 71, a delivery pipe 72, and a spray pipe 73. The diversion pipe 71 is disposed on the outer wall of the mounting base 143, the delivery pipe 72 is connected to the input end of the diversion pipe 71, and multiple spray pipes 73 are disposed on the outer wall of the mounting base 143. The multiple spray pipes 73 are on the same side as the cutting blade 144, and one end of the multiple spray pipes 73 passes through the mounting base 143 and is connected to the output end of the diversion pipe 71.

[0039] Specifically, when using the lathe body 1 to turn the motor side cover, the operator starts the machine body 11 via external equipment and controls the slide 142 to move along the slide rail 141 via the internal drive components of the machine body 11. This moves the mounting base 143 and the cutting tool 144 closer to the motor side cover for turning. During the turning process, the friction between the cutting tool 144 and the motor side cover generates a large amount of heat. To avoid problems such as accelerated wear of the cutting tool 144 and changes in the material properties of the motor side cover due to high temperature, coolant is delivered through the delivery pipe 72 to the distribution pipe 71. The distribution pipe 71 evenly distributes the coolant into each spray pipe 73, and then sprays it out from the outlet of the spray pipe 73, directly acting on the contact area between the cutting tool 144 and the motor side cover. The coolant not only removes a large amount of heat and reduces the temperature of the cutting area, but also acts as a lubricant, reducing the friction between the cutting tool 144 and the motor side cover, thus improving the accuracy and quality of the turning.

[0040] Meanwhile, during the turning process, the control component 4 will precisely control the position of the connecting column 31 and the rotation angle of the rotating block 33 according to the progress and requirements of the turning, so as to ensure that the fixed block 36 always stably abuts against the inner wall of the motor side cover, and together with the clamping block 13 maintains the stable fixation of the motor side cover.

[0041] After the turning is completed, the relevant personnel will reverse the operation through the control component 4 to retract the connecting post 31 into the fixing hole 121. The fixing block 36 will no longer press against the inner wall of the motor side cover, and the clamping block 13 will also release its clamping on the motor side cover. At this time, the turned motor side cover can be easily removed from the mounting post 12.

[0042] like Figure 2 As shown, the cutting assembly 14 also includes a control assembly 2.

[0043] The control component 2 includes a crossbeam 21, a fixed seat 22, a limiting column 23, and a power source 24.

[0044] The crossbeam 21 is installed inside the body 11, the fixed seat 22 is slidably installed inside the crossbeam 21, one end of the limiting post 23 is connected to the fixed seat 22, and the other end of the limiting post 23 passes through the mounting seat 143 and is connected to the slide seat 142. At least one power source 24 is provided, and at least one power source 24 is located at the bottom of the fixed seat 22. The output shaft of the power source 24 is connected to the mounting seat 143.

[0045] It should be noted that the power source 24 described in this embodiment is a locking cylinder, whose main function is to control the mounting base 143 to drive the cutting tool 144 to move to different heights.

[0046] Specifically, when using the main body 1 of the turning machine to turn the motor side cover, the operator will start the power source 24 according to the different turning requirements of the motor side cover. The output shaft of the power source 24 pushes or pulls the mounting seat 143. Since one end of the limiting post 23 is connected to the fixed seat 22 and the other end passes through the mounting seat 143 and is connected to the slide 142, the mounting seat 143 can be adjusted in height along the limiting post 23 under the restriction of the limiting post 23.

[0047] like Figure 4 , Figure 5 and Figure 7 As shown, the fixing mechanism 3 also includes a control component 4 and a limit component 5.

[0048] The control component 4 is mounted on the connecting column 31, and the limiting component 5 is mounted on the outer wall of the connecting column 31.

[0049] The control component 4 includes a control column 42 and a connection component 44.

[0050] The connecting groove 32 has an installation cavity 41, which is connected to the connecting groove 32. One end of the control column 42 is connected to the inner bottom wall of the installation cavity 41, and the other end of the control column 42 is connected to the rotating block 33. The side wall of the installation cavity 41 has multiple connecting holes 43, and the connecting component 44 is disposed in the connecting hole 43.

[0051] The connecting assembly 44 includes a connecting rod 441 and a control ring 442.

[0052] The outer wall of the mounting column 12 is provided with multiple sliding grooves 122, and the multiple sliding grooves 122 are respectively connected to the fixing holes 121. Multiple connecting rods 441 are provided, and one end of the multiple connecting rods 441 is respectively connected to the other end of the control column 42. The other end of the multiple connecting rods 441 passes through the corresponding connecting holes 43 and sliding grooves 122 and is connected to the control ring 442.

[0053] The limiting component 5 includes a limiting block 52.

[0054] The inner wall of the fixing hole 121 is provided with multiple limiting grooves 51, and multiple limiting blocks 52 are provided. The multiple limiting blocks 52 are respectively provided on the outer wall of the connecting column 31, and the multiple limiting blocks 52 are slidably connected to the corresponding limiting grooves 51.

[0055] Specifically, before machining the motor side cover using the lathe body 1, the operator first places the motor side cover on the mounting post 12 and initially fixes it using multiple clamping blocks 13. Then, the operator pushes the connecting post 31 outward using the control ring 442, ensuring that one end of the connecting post 31 contacts the inner wall of the motor side cover. The operator then rotates the control ring 442, causing the connecting rod 441 to rotate within the connecting hole 43. The connecting post 31, however, is restricted within the fixing hole 121 by the limiting block 52 and cannot rotate. Therefore, the connecting rod 441 drives the control post 42 to rotate within the mounting cavity 41, which in turn causes the control post 42 to rotate the rotating block 33. As the rotating block 33 rotates, the approach block 34 rotates accordingly, moving the fixing post 35 outward, causing the fixing block 36 to press against the inner wall of the motor side cover, thus cooperating with the clamping blocks 13 to securely fix the motor side cover.

[0056] like Figure 6 As shown, the control component 4 also includes a positioning component 6.

[0057] The positioning component 6 includes a telescopic rod 61, a latch 62, and a spring 63.

[0058] The control column 42 has multiple mounting slots 421 on its outer wall, multiple telescopic rods 61 are provided, and one end of each telescopic rod 61 is connected to the inner wall of the corresponding mounting slot 421. The other end of each telescopic rod 61 is connected to a latch 62. The surface of the latch 62 has two symmetrical inclined surfaces. Multiple springs 63 are provided, and each spring 63 is sleeved on the outside of the corresponding telescopic rod 61. The two ends of each spring 63 are connected to the inner wall of the corresponding mounting slot 421 and the latch 62, respectively. The inner wall of the mounting cavity 41 has multiple slots 65, and each latch 62 is engaged in the corresponding slot 65. Each slot 65 is composed of two inwardly inclined grooves.

[0059] It should be noted that the top of the latch 62 described in this embodiment has two symmetrical inclined surfaces, and its main function is that when rotating, the inclined surfaces of the latch 62 will contact the edge of the slot 65. Due to the guiding effect of the inclined surfaces, the latch 62 will slide out or slide into the slot 65 relatively smoothly under the action of the telescopic rod 61 and the spring 63.

[0060] Additionally, it should be noted that the slot 65 described in this embodiment also has two symmetrical inclined surfaces. Their main function is to guide the bolt 62 in conjunction with the inclined surface of the bolt 62 during rotation, so that it can slide out or into the slot 65 more smoothly.

[0061] Specifically, when the control ring 442 is rotated, the control column 42 rotates within the mounting cavity 41 under the influence of the connecting rod 441. As the control column 42 rotates, the latch 62 is compressed by the inner wall of the slot 65, causing the telescopic rod 61 to retract and the spring 63 to compress. As the control column 42 continues to rotate, when the latch 62 rotates to the next slot 65, the spring 63 extends due to its elastic restoring force, pushing the telescopic rod 61 and causing the latch 62 to engage in the new slot 65, thus positioning the rotation of the control column 42. This ensures that the fixing block 36 can precisely abut against the inner wall of the motor side cover, providing a stable and reliable fixing effect for the turning process.

[0062] In summary, the electric vehicle motor side cover turning device of this application embodiment allows the operator to control the connecting column to rotate in the mounting cavity through the control component, thereby pushing the fixing block outward and making it contact the inside of the side cover. At the same time, the positioning component fixes the position of the fixing block, so that it will not loosen or be clamped too tightly during the processing, thus preventing the side cover from deforming and effectively avoiding the side cover from springing back.
