Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a vertical machining center fixture for machining motor shafts. Background Technology

[0002] An electric vehicle is a car that uses electricity as its sole or primary power source. It is powered by an onboard rechargeable energy storage system, which drives an electric motor to move the vehicle. The motor shaft is one of the core components of the electric motor. As the hub for the conversion of mechanical energy into electrical / kinetic energy, it plays a crucial role in transmitting power and motion and is the "heart" of the electric vehicle's drive system.

[0003] During the production process, motor shafts typically require the drilling of center holes or coolant channels at the shaft end or inside. This necessitates the use of vertical fixtures to clamp the motor shaft. However, existing fixture technologies for motor shaft machining often involve cumbersome procedures to clamp and fix the motor shaft, and it is difficult to achieve efficient alternating operation of the clamping mechanism during machining. This results in a complex clamping and fixing process during motor shaft machining, making it difficult to effectively improve machining efficiency.

[0004] Therefore, a vertical machining center fixture is needed for machining motor shafts to solve the problem of cumbersome clamping and fixing process of motor shafts during hole machining in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a vertical machining center fixture for machining motor shafts, so as to solve the problem of cumbersome clamping and fixing process of motor shafts during hole machining in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vertical machining center fixture for machining motor shafts, comprising a vertical plate, two sets of clamping mechanisms provided on the vertical plate, and a positioning component provided on the vertical plate; Each clamping mechanism includes a V-block bolted to one end of the vertical plate, a clamping cylinder bolted to one end of the vertical plate and close to the V-block, and a pressure plate rotatably mounted on the output end of the clamping cylinder and cooperating with the V-block.

[0007] It should be noted in the solution that the positioning component includes a base plate installed on the bottom surface of the upright plate and two top points installed on the top surface of the base plate by bolts and corresponding one-to-one with the two V-blocks.

[0008] It is worth noting that each of the two V-blocks has an L-shaped plate bolted to one side, and the L-shaped plate has a movable elastic pin.

[0009] Furthermore, it should be noted that two parallel right-angled seats are bolted to the other end of the upright plate and the top surface of the base plate.

[0010] In a preferred embodiment, each of the V-blocks and the corresponding pressure plate clamps the motor shaft body, and the tips of the two top points are inserted into the center hole at the bottom of the corresponding motor shaft body.

[0011] In a preferred embodiment, both pressure plates are rotatably connected to the bodies of the corresponding clamping cylinders via connecting rods, and the outer surfaces of both elastic pins are in contact with the outer surfaces of the corresponding motor shaft bodies.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The motor shaft is positioned in the center hole by a set tip, and the motor shaft is prevented from tilting by a set elastic pin. The clamping cylinder drives the pressure plate to rotate, so that the pressure plate and V-block clamp the motor shaft. The operation is simple and effectively avoids the cumbersome clamping and fixing process of the motor shaft during hole machining. Attached Figure Description

[0015] 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.

[0016] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a vertical plate 1, two sets of clamping mechanisms 2 are provided on the vertical plate 1, and a positioning component 3 is provided on the vertical plate 1; Each clamping mechanism 2 includes a V-block 21 bolted to one end of the vertical plate 1, a clamping cylinder 22 bolted to one end of the vertical plate 1 and close to the V-block 21, and a pressure plate 23 rotatably mounted on the output end of the clamping cylinder 22 and cooperating with the V-block 21.

[0017] Specifically, after positioning the motor shaft to be processed inside the V-block 21, the clamping cylinder 22 is activated to push the pressure plate 23 to rotate, so that the pressure plate 23 cooperates with the V-block 21 to clamp the positioned motor shaft, thereby realizing the clamping operation.

[0018] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the positioning component 3 includes a base plate 31 installed on the bottom surface of the upright plate 1 and two tips 32 that are bolted to the top surface of the base plate 31 and correspond one-to-one with the two V-blocks 21.

[0019] Specifically, when the motor shaft is placed inside the V-block 21, the tip of the center 32 is inserted into the center hole at the bottom of the motor shaft, and the motor shaft is positioned through the center hole.

[0020] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that each of the two V-shaped blocks 21 has an L-shaped plate bolted to one side, and the L-shaped plate has a movable elastic pin 4.

[0021] Specifically, before clamping the motor shaft, the elastic pin 4 is pulled away from the V-block 21 and rotated to fix it, so that the V-block 21 is not affected by the elastic pin 4. After the motor shaft is positioned inside the V-block 21, the elastic pin 4 is reset so that the elastic pin 4 blocks the motor shaft and prevents the motor shaft from tipping over.

[0022] Further as Figure 3 As shown, it is worth noting that two parallel right-angled seats 5 are bolted between the other end of the upright plate 1 and the top surface of the base plate 31.

[0023] Specifically, the two right-angled seats 5 set between the upright plate 1 and the base plate 31 enhance the stability of the connection between the upright plate 1 and the base plate 31.

[0024] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that each V-shaped block 21 and the corresponding pressure plate 23 clamps the motor shaft body 6, and the tips of the two top points 32 are inserted into the center hole at the bottom of the corresponding motor shaft body 6.

[0025] Specifically, the motor shaft body 6 is positioned by inserting the tip of the tip 32 into the center hole of the motor shaft body 6 and using the center hole positioning method.

[0026] Further as Figure 1 and Figure 2 As shown, it is worth noting that both pressure plates 23 are rotatably connected to the body of the corresponding clamping cylinder 22 via connecting rods, and the outer surfaces of both elastic pins 4 are in contact with the outer surfaces of the corresponding motor shaft body 6.

[0027] Specifically, when the clamping cylinder 22 pushes the pressure plate 23 to rotate, the pressure plate 23, together with the V-block 21, clamps the motor shaft body 6. Through the set elastic pin 4, after the motor shaft body 6 is positioned, the elastic pin 4 can prevent the motor shaft body 6 from tipping over.

[0028] In summary: When using this fixture, first install the upright plate 1 onto the external processing equipment. Pull the elastic pin 4 away from the V-block 21 and rotate it downwards to fix it. Then, place the motor shaft to be processed into the V-block 21, so that the center hole at the bottom of the motor shaft is inserted into the corresponding center 32. After initially positioning the motor shaft, reset the elastic pin 4 so that the outer surface of the elastic pin 4 contacts the outer surface of the motor shaft, limiting the motor shaft and preventing it from tipping over on the V-block 21. Then, open the clamp. The clamping cylinder 22 pushes the pressure plate 23 to rotate, so that the pressure plate 23 clamps the motor shaft placed in the V-block 21, thereby clamping and fixing the motor shaft that needs to be processed. Then, the top of the motor shaft is machined by external processing equipment. During the processing, another set of clamping mechanisms 2 simultaneously performs the clamping operation on the motor shaft, so that the two sets of clamping mechanisms 2 work alternately, improving the processing efficiency of the motor shaft. The operation is simple and effectively avoids the cumbersome clamping and fixing process of the motor shaft during the hole processing.
