Description

Technical Field

[0002] Sand core is an essential process for making low-pressure casting new energy water-cooled motors. After the motor casing is made, sand vibrating equipment is needed to make the sand core fall off the inner wall of the motor casing.

[0003] For example, the Chinese utility model patent application number is CN202020471862.3, which discloses a special vibrating sand machine for water-cooled motor casings, which clamps the motor casing on a platform, and then uses an air hammer a to hammer at high frequency to separate the sand core from the inner wall of the motor casing. As for the clamping equipment of the motor casing, such as the Chinese utility model patent application number CN201921878803.1, which discloses a clamp for low-pressure casting motor casings, the clamping mechanism can only achieve a stable clamping effect on the motor casing, and the motor casing cannot be rotated or adjusted in position during the clamping process, so that the air hammer a can only hammer a certain position of the motor casing, and the other positions can only rely on the vibration transmission force to achieve the sand core shedding, so the effect of removing the sand core from the motor casing is poor. Summary of the invention

[0004] In order to make up for the above shortcomings, the present application provides a low-pressure casting motor casing clamping assembly, which can not only achieve the clamping effect, but also assist the motor casing in rotating or adjusting the position, so that the air hammer a can directly hit various positions of the motor casing more comprehensively, thereby making the sand core removal effect of the motor casing better.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0024] See also Figure 1-Figure 5 The present application provides a low-pressure casting motor housing clamping assembly, comprising a rotating clamping member 1 and a motor housing displacement member 2:

[0025] The rotating clamping member 1 includes a U-shaped frame A11 and a clamping portion A12 rotatably mounted on one side of the inner wall thereof, a cylinder 13 is provided on the other side of the inner wall of the U-shaped frame A11, a servo motor A14 is provided at the movable end of the cylinder 13, a clamping portion B15 is provided at the output end of the servo motor A14, and the clamping portion A12 and the clamping portion B15 jointly clamp and fix the motor housing;

[0026] The motor housing displacement member 2 is fixed to the U-shaped frame A11 and is used to drive the motor housing to move laterally.

[0027] In this embodiment, the clamping part A12 is first inserted into one side of the motor casing, and the cylinder 13 is started to insert the clamping part B15 into the other side of the motor casing, so that the clamping part A12 and the clamping part B15 jointly clamp and fix the motor casing, and then the external air hammer a is controlled to vibrate and hit the outer wall of the motor casing. By starting the servo motor A14, the motor casing clamped by the clamping part A12 and the clamping part B15 can be rotated, and the motor casing displacement member 2 can be used to cause the motor casing to produce a lateral displacement, so that the air hammer a can more comprehensively hit all directions of the motor casing, so that the motor sand core cleaning effect is better.

[0028] See also Figure 1-Figure 3 , Figure 5 , the clamping part A12 and the clamping part B15 have the same specifications;

[0029] The clamping part B15 includes a fixing plate 151, and fixing blocks 152 are provided on both sides of the fixing plate 151 close to the motor housing, and locking bolts 154 are connected to the fixing blocks 152. Screw holes 1511 adapted to the locking bolts 154 are equidistantly provided on both sides of the fixing plate 151, and T-shaped clamping blocks 153 for clamping and positioning the motor housing are installed on the fixing blocks 152. Specifically, the motor housing can be clamped and fixed by using the T-shaped clamping blocks 153, and the spacing between the two T-shaped clamping blocks 153 on the fixing block 152 can be adjusted by using the combination of the locking bolts 154 and the screw holes 1511, thereby facilitating the clamping and fixing of motor housings of different sizes.

[0030] See also Figure 5 A rubber pad that is movable and closely attached to the motor housing is adhered to the T-shaped clamping block 153. The design of the rubber pad can protect the motor housing during the clamping and fixing process, reducing the probability of damage to the motor sand core during the vibration and crushing process.

[0031] See also Figure 1-Figure 3 A rotating shaft 16 is also provided on the side of the fixing plate 151 in the clamping part A12 away from the motor housing, and the rotating shaft 16 is rotatably connected to one side of the inner wall of the U-shaped frame A11. A bearing is embedded on one side of the inner wall of the U-shaped frame A11, and one end of the rotating shaft 16 is fixed in the inner ring of the bearing. The matching of the bearing and the rotating shaft 16 facilitates the clamping part A12 to rotate following the drive of the servo motor A14.

[0032] See also Figure 1 , Figure 2 and Figure 4 The motor housing displacement member 2 includes a U-shaped frame B21 and a displacement driving part 22 arranged thereon, and the displacement driving part 22 is connected to the side of the U-shaped frame A11.

[0033] The displacement driving unit 22 includes a servo motor B221 installed on one side of the inner wall of the U-shaped frame B21, the output end of the servo motor B221 is connected to a ball screw pair 222, the outer wall of the ball screw pair 222 is provided with a screw nut 223, a slider 224 is fixedly connected to the outer wall of the screw nut 223, a slide rail 211 adapted to the slider 224 is provided on the inner wall of the U-shaped frame B21, and the screw nut 223 is also fixed to the side of the U-shaped frame A11. Specifically, the servo motor B221 is started to drive the ball screw pair 222 to rotate, and under the cooperation of the slider 224 and the slide rail 211, the screw nut 223 can be displaced along the ball screw pair 222, thereby enabling the U-shaped frame A11 to be displaced laterally, indirectly causing the motor housing to be displaced laterally.

[0034] It should also be noted that the U-shaped frame B21 is located on the side of the U-shaped frame A11, and the inner side of the U-shaped frame B21 faces the side of the U-shaped frame A11. In this way, when the sand core slag falls later, the probability of falling directly onto the slide rail 211 or the ball screw pair 222 is reduced, thereby making the application more stable.

[0035] See also Figure 1 The U-shaped frame B21 is fixedly connected with support frames on both sides. The design of the support frame can make the present application be at a certain distance from the ground, so that the sand core fragments broken by the air hammer a have space to fall.

[0036] When using this application:

[0037] Insert the clamping part A12 into one side of the motor casing first, start the cylinder 13 to insert the clamping part B15 into the other side of the motor casing, so that the clamping part A12 and the clamping part B15 clamp and fix the motor casing together, and then control the external air hammer a to vibrate and hit the outer wall of the motor casing, and by starting the servo motor A14, the motor casing clamped by the clamping part A12 and the clamping part B15 can be rotated, and the servo motor B221 is started to drive the ball screw pair 222 to rotate. With the cooperation of the slider 224 and the slide rail 211, the screw nut 223 can be displaced along the ball screw pair 222, so that the U-shaped frame A11 can be displaced laterally, which indirectly causes the motor casing to be displaced laterally, so that the air hammer a can more comprehensively hit all directions of the motor casing, so that the motor sand core cleaning effect is better.

[0038] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
